Rainbow Ant Colony (Part 1)

Rainbow Ant Colony (Part 1)


Hi, this is Jordan and in this video I’ll be
showing you my Iridomyrmex bicknelli colony, which is a really common species here in Australia. You can find
them just about anywhere. This colony has around 150 to 200 workers and it’s just over a year old. Similar
to my Pheidole colony, they’ve actually grown
quite a lot last few months. You can see the Queen here sitting on a pile of her eggs. I apologize for the image quality. This
colony is a little difficult to to film because it’s hard
to get light into certain parts of the nest. As you can see
there’s heaps of pupae, larvae and lots of eggs. I expect them to slow down in
development soon because we’re approaching winter here in
Australia so it’s starting to get quite cold. I have decided to start heating my colonies. here you can see I’ve set up a heating mat which sits underneath the nest and I only have a small portion of the nest actually touching the
mat, what this does is create a temperature gradient throughout the
nest. This allows the colony to position themselves in
optimal temperature conditions. Which is really good way to promote their activity and growth.
It’s also interesting to see which areas they
allocate for certain purposes. I usually find the pupae gets
placed in the warmer chambers and the Queen, larvae and eggs into the cooler
chambers. So here’s the outworld I’ve got set up for them. It’s about the same size as the nest and I’m thinking of introducing a larger one soon, just to give the ants more room to explore. This colony consumes
quite a lot of food usually I feed them at least once every
day. For a source of protein I usually feed
them meal worms and crickets and
occasionally bits of chicken and ham. They love to have a variety of different foods to
choose from. I notice if I give them say mealworms for a week straight, they’ll pay less and less attention to them and as
soon as I give them something they haven’t had in a while they’ll just swarm on
that new source of food. For sugary food sources I give them pieces of fruit and honey and
they really love honey and will
consume every last drop that I give before they even touch the fruit. So
that’s all the footage I have for now, thanks for watching and I hope you got something out of this.

Ants vs. Axolotl

Ants vs. Axolotl


Last week, we built the Blood Towers, the
beastly ant territories of the Dracula Ants. Check out those fruit flies, circling like
crows outside the towers, but next door to these ant newcomers, lays another kingdom
of old, of the O.G. Ant Trinity, that has long been established
in the Antiverse. It’s an ant kingdom we, the AC Family, call
the Hacienda Del Dorado, home to the Golden Empire, a mighty supercolony of yellow crazy
ants. But there has been a great change in the Hacienda
Del Dorado since we last visited these territories, that has tipped the balance within the kingdom. Have a look at this. If you’re new here, this is what the feeding
grounds used to look like! Today the crowds of Golden Empire ants have
been reduced to only a few seen rummaging through the debris. But what had happened to the once glorious
Golden Empire? Well, AC Family, what you’re seeing here,
is a great transition that all the inhabitants of the Hacienda Del Dorado are undergoing,
as a result of a single kingdom-shaking event. The disappearance of an emperor, and the entrance
of a dragon. Ladies and gentlemen, welcome to the AntsCanada
Ant Channel! Please SUBSCRIBE to my channel and hit the
bell icon. Welcome to the AC Family! Enjoy! Alright, AC Family, I know some of you who
have been following the channel for awhile, may be die-hard Golden Empire loyalists or
fans of Emperor Sapphire, but if you are, don’t panic. I’ll explain everything that has happened
in detail, so keep on watching until the end. But for you newcomers, who may be wondering
what is going on, let me catch you up to speed! This waterfall and pool called the Golden
Springs were installed for population control, as the less nimble ants would be swept and
swallowed up by its falls, and living within its waters, was the Golden Empire’s resident
Kraken, a blue crayfish that we all watched grow up here. We had named it Emperor Sapphire, an awesome
and sensitive beast, whose main purpose was to feed on decaying ant bodies which fell
into the Golden Springs, thereby keeping these waters consistently crystal clear. But now he’s gone. Here’s what happened. Months passed and Emperor Sapphire began to
grow bigger and bigger slowly outgrowing the Golden Springs. So, I’m sad to announce, that it was no longer
fair nor healthy to restrict our blue crayfish to the limiting waters of the Golden Springs,
and after his latest shed, I had to rehome him, leaving the Golden Springs completely
evacuated. His royal absence, however eventually lead
to a build up of algae within the Golden Springs, since there was now noone to take care of
cleaning duties, and the water grew foul as more and more dead ant bodies collected untouched. But now you may be wondering how this lead
to the staggering population decline in the Golden Empire. Now you may be thinking the ants drank this
foul water and died off in masses, but actually, although the absence of the Sapphire Emperor
was indeed the cause of the disappearance in ants, it’s not what you’re thinking. In fact, the Golden Empire has not been dying
out. They’re still here in the Hacienda Del Dorado,
and I’m about to show you where they’ve all been hiding. It’s night, and a gift is about to fall from
the skies. It’s the Golden Empire’s feeding time! At the arrival of the chopped up roaches,
a group of ants come boiling out from within their deepest of catacombs, to feast on the
food offerings that fall from the skies every night. Have a look! Message spreads fast by way of pheromones
that food has arrived at the surface, springing more and more ants into action to help with
processing the food. More squadrons of ants appear on the scene
to carry these massive pieces of fresh roach meat. Look at them cooperating and carrying the
roach pieces from all sides, as they pull and plan their operations of food transport. And now suddenly the feeding grounds are as
populated as we’re used to seeing them. But AC Family, here’s where they’ve been hiding
all this time. Within the soils of the terrarium there is
a damp layer. I’ve been purposely drying out the lands for
a reason I’ll get into in a bit, but it has caused the ants of the Golden Empire to retreat
deep into this layer of moist soil. AC Family, check out all those amazing chambers
and tunnelwork, and all the ants pouring out from their openings! We’ll be seeing some special guest appearances
later on in the video at this particular cross section of the nest, so hang tight for that
in a little bit. Meanwhile, as for this roach, they’ll be working
on fitting it into the nest, then disappear again deeper into the moist soil layer. So let’s shut the lights and allow these ants
to deal with their food in peace. Now I’m sure many of you may be glad to know
the Golden Empire is OK and healthy as usual. But why then have I attempted to dry out the
lands to keep the ants deeper underground, and what is the connection to the absence
of our Sapphire Emperor? Well, now that the Golden Springs were empty,
and kind of festering, I had some major renovation plans in mind, in order to make these waters
great again, and set the stage for the reception of our Sapphire Emperor’s replacement. That’s right. We needed a new cleaner beast for the Golden
Springs. So, I needed the ants to stay out of my way
as much as possible while this project was in operation, but boy AC Family, did I have
some epic plans for these Golden Springs! A new beast was coming to the Antiverse, AC
Family, and it was unlike anything I’ve ever kept before. The next evening, when the ants were sparse
and retreated out of the way, I went straight to work as quickly as possible, so to not
alarm the ants before they came boiling out to defend their kingdom from the giant divine
hands descending from the skies. Though these ants don’t sting, they are quick
to swarm and can spray formic acid into bites they inflict which cause irritation and lots
of escaped ants using my body as a bridge! I disconnected the filter, and began to scoop
away at the soil. All this substrate needed to go. The beast that would be moving in here would
need more room than the Golden Springs was currently offering! Next, I needed to replace the substrate with
a layer of black sand. I chose the sand so that our new beast would
show up nicely against it! And AC Family, after several hours of work
and renovations… Behold! I’m pleased to present to you the new Hacienda
Del Dorado. Now before I get to the newly restored and
improved Golden Springs, let me show you the awesome changes I made to the lands. The new territories look absolutely gorgeous! I couldn’t look away! It was calming to the eyes. Don’t you guys think? I’ve planted groupings of arrowhead plants,
Syngonium podophyllum, and a cute smaller species which may or may not be creeping wire
vine, Muehlenbeckia axillaris. I find these plants accent our creeping fig
ficus at the back there quite nicely. Another quick thing I wanted to show you guys
were these newcomers! These ferns, which I actually didn’t plant,
sprouted out of nowhere growing epiphytically without soil with our bromeliads. Pretty neat that they sort of planted themselves
and it’s beyond me how they got there! And speaking of making grand appearances on
the scene, guess who else has made a grand comeback to once again frequent the feeding
grounds! They’re back! So check this out, AC Family, now that the
new plants have been installed, and with it new moist soils added, as well as more water
to help the new plants root properly, the lands were no longer dried out as before,
and so the Golden Empire has returned in their great numbers above ground. And let me tell you, working around their
feeding grounds planting the plants was no easy venture! The Golden Empire came pouring out of their
nest, covering my arms, biting and spraying me with formic acid. I’ve never had to work around them like this
for such a long time and for the first time felt and experienced their wrath. Impressive defense line, I must say! But the thing that impressed me the most during
this whole relandscaping operation was just how many ants emerged on the scene! Have a look at this! Masses of ants scrambling about in hi-jinx,
as the colony was made aware of my giant hands ripping and planting around their home. Ants were relocating brood in a panic, I mean,
wouldn’t you? But look who else I caught making moves. A queen! This was one of the 8 royal queens to the
Golden Empire’s supercolony! It was awesome to see her again, and then
out of nowhere a second queen! Totally amazing! It was great seeing our monarchs, even if
it was in this current state of emergency. And so the Golden Empire was now back to normal,
and no longer in estivation brought about by the great drought I had caused, but now
that the colony was back to frequenting all areas of the Hacienda Del Dorado, it was time
to add the finishing touch to the Golden Springs, or should I say, it was time to add the finishing
beast to the Golden Springs. The waterfalls were ready and working, with
waters cascading down its purifying planted surface. Though I had done an 80% water change, some
of the biofilm and sediment from the old substrate had settled on top of our new sand substrate,
which was okay because this valuable gunk contained the necessary bacteria needed to
neutralize the poisonous waste which would be generated by the beast that would be moving
into these waters. I could also see pieces of dead ant remains
in the mix. It was definitely important that these waters
stay as clean as possible, because the Golden Springs happen to be the Golden Empire’s primary
water source. It’s pretty ironic to think that the Golden
Springs happens to give these ants life, bring some of them death, and now, brings them a
new pet dragon, that they have no idea is about to enter these waters. And so AC Family, it is with joy and excitement
that I am pleased to present to you, the Hacienda Del Dorado’s new resident water beast! Behold! Our brand new White Aquadragon, a.k.a. an
axolotl, scientifically known as Ambystoma mexicanum. Now if this is your first time seeing an axolotl,
I’m sure you may think its appearance is as strange as its name, but let me assure you
these creatures are incredible! Although they are commonly known as Mexican
walking fish, these creatures are not actually fish at all. They’re amphibians, closely related to tiger
salamanders. They were originally found living in lakes
in Mexico but sadly are now listed as endangered in the wild due to urbanization, water pollution,
and introduction of invasive predators in their natural habitats in Mexico. Luckily, today they are widely bred within
the captive pet trade, and this makes our aquadragon extra special. Check out those external gills though, and
all the blood vessels extending to the surface to absorb oxygen and expel carbon dioxide. They are basically the inverted version of
our lungs! Super neat, right? This poor axolotl seems to be sustaining an
injury on its tail which it must have gotten from a tank mate biting it. Now these animals are carnivorous, consuming
small prey such as worms, insects, and small fish in the wild, so I had to test and see
if it had a taste for yellow crazy ants, so I placed in a dead ant and it took a quick
swipe but hilariously missed. Oh well, let’s hope it gets better at aiming. As you can see these guys are amazing swimmers
and are 100% aquatic animals, and this white aquadragon of ours appeared eager to move
into his bigger home. I also couldn’t wait to add our white aquadragon
to the Golden Springs, but before that, I first needed to drip acclimate the beast so
that it would gradually adjust to its new future waters. And soon, the beast was ready for its official
release. Here we go AC Family, are you ready? It is time to release our new white aquadragon
into the Golden Springs for the purpose of feeding on drowned members of the Golden Empire. Here we go! 1 – 2 – 3. I placed the axolotl in, and it instantly
hid sitting frozen behind some driftwood. It began to regain its bearings for a bit. I watched wide-eyed as it sat there truly
like a dragon waiting beneath the waters. I truly hoped it would do a good job at consuming
the dead drowned ants. It was so weird to see it living here, because
prior to this, I have always been used to looking in and seeing our Sapphire Emperor. It sat silently for a long while staring at
the new strange world above the water. And then it decided to move, an ant came to
check out the huge white shape it could see below the waters, but the beast was ready
to check out its new home. It swam around the corner and cautiously began
to explore the Golden Springs floor. I am sure it could smell all the dead ants
at its feet but it seemed to not care much for them at the moment. I am sure it could also see all the ants crawling
around the other side of the glass, but again not too interested in them either. It moved to check out the filter, which it
could probably feel was making strange mechanical vibrations. And then what it did next kind of touched
my heart. It was staring out at the vast world of the
Hacienda Del Dorado outside the waters. It suddenly occurred to me that this was probably
the very first time, our axolotl had ever seen plants, soil, wood, and even ants. It stood still staring for a long time at
the beauty beyond. OMG! Were these creatures smart? Then suddenly it began to move, probably hoping
to explore the rest of the Hacienda Del Dorado. Ugh my heart. It eventually turned around and began to continue
mapping the edges of its watery domain. Now it’s said that the minimum requirement
for an axolotl is 10 gallons and the Golden Springs, now with most of its substrate removed
was about 10 gallons, more wide than tall, but I surely began to feel guilty keeping
it within the said minimum required space. What do you guys think? Anyway, it continued to look around at the
world beyond the Golden Spring’s pool. For now, I was going to let it settle in to
its new home where it would take up the task of feeding on drowned members of the Golden
Empire. I watched our white aquadragon for one last
moment as it retreated towards the back to retire for sleep. The next morning, I came to visit the Hacienda
Del Dorado, and could see our white aquadragon from a mile away against that dark substrate,
and strangely, I believe it also saw me coming. It turned to face me as soon as I walked through
the door! Ugh my heart! Why was I feeling guilty for keeping it the
Golden Springs? I felt like it needed something bigger. Well, the good thing was the axolotl seemed
a lot more settled in now, and also appeared to be less stressed and a nicer colour. Also the water had cleared up quite nicely,
the black sands now visible, with all that biofilm from the night before probably settled
in our filter and crevices within the waterscape to do its job at neutralizing our axolotl’s
waste. Now get this, AC Family, another great thing
I noticed was its tail had healed nicely overnight! This is actually one of the most amazing features
about axolotls. They’re super healers! Surprisingly axolotls don’t heal by scarring,
but are capable of regenerating entire lost appendages in a period of months, and, in
certain cases, more vital structures like parts of their brains. Isn’t that amazing?! They can also readily accept transplants from
other individuals, including eyes and parts of the brain, restoring these alien organs
to full functionality. It’s pretty mind-blowing if you think about
it! Now as I watched the axolotl pace around its
living space, I wondered if it was perhaps hungry. It was hard to tell if it was eating ants
or if simply didn’t have a taste for them. There were no more dead ant bodies along the
floor, so could that mean it could have eaten them overnight? But just in case our white aquadragon was
hungry, I decided to give it a house warming gift anyway, as is our AC tradition. Here I had some thawed, frozen bloodworms,
an apparent axolotl favourite. I dropped some into the Golden Springs, and
the blood worms fell straight to the bottom. I instantly knew the axolotl could smell them
as suddenly bam! Some must have floated towards her and she
sucked them up into her mouth. It began to feed happily on the bloodworms,
and when it was done, it moved over to continue ant watching. Speaking of which, the Golden Empire was back
with business as usual. Check them out! They were as busy as ever reconstructing tunnels
and ant hills within the new rich soils, and by the way, do you recognize where this new
soil came from? Ten points if you can tell where in the comments. Now with all the ants now back to frequenting
the Golden Springs, back to traveling their usual trails around the waters, to collect
a drink and distribute the waters within their bodies to all members of the colony, there
was now an added pressure for our white aquadragon to fulfill its task as water cleaner, as effectively
as our former Sapphire Emperor had during his term in the Golden Springs. Which brings me now to me dilemma, AC Family! Here’s where I need your help. What should we do? Do you think this axolotl was a good choice
for our Golden Springs? Although the axolotl does seem happy, a part
of me is starting to doubt this choice for a water beast, because even if the Golden
Springs are the alleged minimum required space, I still get the sense this area is too small,
plus I have yet to actually see if it is eating the dead ants. To be fair, it’s only been a few days and
I plan on keeping a good eye on our white aquadragon here, feeding it bloodworms daily,
but I’d love to know what you guys think? Should we rehome this axolotl and replace
it with perhaps another crayfish? If you do think we should give this axolotl
a chance in the Golden Springs, what should we name it? Let me know your thoughts in the comments
section, AC Family. As always you determine the fate of the inhabitants
of the Golden Empire, and ultimately, the Antiverse. I love these ants and want what’s best for
them, including clean drinking water free of the poisons generated by any drowned bodies. The lives of the Golden Empire and this new
axolotl lay in your hands. Like a massive ant colony ourselves, I believe
collectively we’ll be able to make the right choice. It’s ant love forever! Alright AC Family, did you enjoy this week’s

What Is an Inner Ear Infection? | Ear Problems

What Is an Inner Ear Infection? | Ear Problems


Ear infections can involve any of the three
anatomical parts of the ear. The outer ear, the middle ear, or the inner
ear. Inner ear infections are almost always viral. It is very unusual to have a bacterial infection
of your inner ear. Viral inner ear infections can effect either
the organ of hearing or the organ of balance. When the organ of hearing is affected, the
infection will usually present as a sudden hearing loss. It will not present with pain. In addition to hearing loss, it may cause
a ringing noise in the ear, which we call tinnitus, or a sense of fullness or distortion. Viral infections of the organ of balance present
as imbalance or vertigo. Vertigo is the false sensation of motion,
such as the room spinning or the floor rocking. Occasionally viral infections of the inner
ear will effect both the organ of hearing and the organ of balance and the individual
might present with hearing loss, tinnitus or ringing in their ear, and dizziness, all
at the same time. The treatment for viral infections of the
inner ear is usually oral steroids such as Prednisone, if there are no contraindications. In other words, if you don’t have a disease
which might be made worse by the Prednisone. Inner ear infections are generally viral,
and they can effect either the organ of hearing, or the organ of balance, or both. If they effect the organ of hearing, they
will cause hearing loss, and if they effect the organ of balance, they will cause dizziness.

Asepsis and Infection Control Unit 5 Nursing Fundamentals F18

Asepsis and Infection Control Unit 5 Nursing Fundamentals F18


Hello and welcome to the unit 5 lecture on asepsis and infection control. Your Competency for this is to provide nursing care with for patients with infection. Your learning objectives are here. Again, Please familiarize yourselves with them in preparation for class and in preparation for the exam. So there’s many agents and organisms that cause infection. Bacteria and viruses are probably the most common. Unfortunately, multi drug-resistant organisms, or superbugs, are becoming more common. These superbugs are particularly concerning because they’re resistant to certain antibiotics. This really limits treatment options for patients. Treatment becomes even more limited if the patient is or develops an allergy to antibiotics that would normally work. Infection requires each one of the six genes to be present. So we break any link in the chain of infection to stop infection. And what’s the most important? Hand-washing! Hand-washing is the most important way we can stop the spread of infection and break that chain. Healthcare associated infections, also known as nosocomial infections, are infections that happen to patients receiving medical care. They can happen as a result of antibiotic use. These are called multi drug-resistant infections and they happen as bacteria mutate and become resistant to antibiotics. They can also happen as a result of devices used in healthcare such as central lines and Foley catheters. Nosocomial infections are a real problem for patients who are probably already compromised and this adds to their healthcare needs. Reimbursement for complications of HAI’s may be denied and this leaves hospitals without revenue. Additionally these increase costs, the length of stay, and patient mortality rates. Hand hygiene is the most important thing you can do to stop the spread of infection. So when should you wash your hands?always? Always, it seems! At the beginning and end of your shift, before and after contact with the patient, between contacts with different patients, before and after contact with wounds, dressings, specimens or bedclothes, before performing any invasive procedure, before administering medications, after contact with any patient secretion or excretion, after body fluid exposure, after contact with the patient’s environment, before and after you use the bathroom, after sneezing coughing or blowing your nose, and especially after removing your gloves. When in doubt wash even if you had gloves on. Gloves don’t eliminate the need for hand hygiene because gloves might have microscopic tears or holes that we can’t see and this actually allows bacteria onto our hands. Hand sanitizer is an acceptable alternative, but not with c-diff. It doesn’t kill the spores. So remember soap and water is a must for c-diff! Also keep your fingernails short and avoid nail polish. Personal protective equipment or PPE is used when we need extra protection based on how the illness or diseases spread. So for example, influenza is spread by droplets so we need a mask when caring for these patients. And that’s to protect us from catching their influenza. Standard or universal precautions are used with every patient. They include basic precautions like hand washing and wearing gloves. The Centers for Disease Control recommends treating every patient as though they’re infectious. There’s no way to tell that a patient might be infected with hepatitis or HIV until they’re in their later stages. So anytime there’s a risk of getting blood or body fluids splash on you, please wear a protective personal equipment and make it appropriate- so like goggles, mask, and a gown if you’re thinking there’s gonna be a splash. And then remove contaminated items as soon as possible and of course wash your hands! Isolation precautions are special precautions used in conjunction with universal precautions for patients with certain communicable diseases like MRSA and TB. Contact precautions include wearing gloves and a gown when entering the patient’s room and this is for diseases like MRSA. Anytime of patients on isolation precautions they should have their own dedicated equipment like a blood pressure cuff or stethoscope that gets left in the room, and this is to minimize the risk of spreading the disease to other patients. Modified contact percussions are the same as contact but the only difference is they require the use of soap and water instead of hand sanitizer, and like I mentioned this is for c-diff. Droplet precautions require the use of gloves and a surgical mask and it’s indicated for diseases like disseminated shingles and influenza. Airborne precautions require a negative pressure room and the use of a special respirator mask as well as a gown and gloves and this is indicated for TB and some others as well. Reverse isolation on the other hand is used in high-risk situations to prevent infection in people whose body defenses are known to be compromised. This is to prevent the patient from us so they don’t get sick. So if we are caring for patients in isolation, we need to realize how this affects the patient and the patient’s feelings about themselves, so patients might feel dirty or like we don’t want to be around them. So we need to be very careful to use therapeutic communication techniques when we interact with patients in isolation. And it’s important to maintain regular contact with isolated patients. They’re really at risk for neglect and failure to rescue type situations. So in one study in 2003 It was found actually that compared with controls patients isolated for infection control precautions experience more preventable adverse events, expressed greater dissatisfaction with their treatment and have less documented care. This supports that idea that they’re at risk for failure to rescue and neglect and You know their emotional well-being might suffer as a result. Why? Why does this happen to them? Well it takes extra time out of an already busy day to put for nurses to put gown and gloves on and so they may be less likely to go in there resulting in the patient getting less care that they need. We need to make sure that we’re making time for our isolated patients because we don’t want to be negligent of their care or their healthcare needs. So what’s our normal resistance? Well the big one is intact skin. This is a first line of defense against infection. Normal skin flora protect us against harmful bacteria. Leukocytes, which are your white blood cells and the inflammatory response is the second line of defense against infection. The inflammatory response is a nonspecific response to tissue injury. So what happens as blood vessels dilate it lets the white blood cells get to the area and attack and ingest the bacteria. So this leads to redness which is your erythema, warmth, edema, pain and functional impairment from edema & pain. At this stage the tissue is inflamed, but it’s not infected. So then what might happen is a collection of dead leukocytes, digested bacteria, dead tissue cells and plasma may result in pus formation. Fever increases cell metabolism and interrupts viral replication and slows down bacterial growth and this increases leukocyte mobility and action. So that is why often times when people have infection especially a systemic infection they get a fever. So sometimes normal resistance from infection doesn’t work and this could be due to a compromised host and this could be anything from a break in the skin and mucous membranes to invasive devices, stasis of body fluids, inadequate nutrition stress and hyperglycemia, or immune system dysfunctions like AIDS or cancer. So stasis of body fluids like when patients are sedated and paralyzed and have a breathing tube in place, can result from decreased coughing and sneezing, because we’re taking these protection mechanisms away and then they don’t clear their respiratory secretions. So this can lead to pneumonia. Malnutrition decreases the body’s ability to make antibodies and white blood cells and this makes it hard to fight infection and increases metabolic needs, and stress causes cortisol release which suppresses immune system response and increases serum glucose. And this is ideal for bacterial growth And that is why good glycemic control is imperative for hospitalized patients. People with diabetes or just the elevated blood sugars from a stress response in general makes wound healing slow and can lead to infection. Immune system dysfunction also can cause problems. So like we said with cancers, leukemia increases the production of leukocytes. But they’re immature and they can’t fight infection. And then AIDS also causes poorer immunity. And finally drug therapies such as chemo or steroids or inappropriate about it Antibiotic use excuse me, also contribute to poor infection resistance. So let’s talk for a little bit here about the infectious process. So acute infection is a short duration like pneumonia, whereas chronic infection can last quite a while and this example would be like c diff infections which can be devastating the patient’s because they linger on for years and some people never get rid of them. Local infection is localized to a single body area and then systemic infection is infection that is spread to other areas or organs in the body. Bacteremia is infection that spreads through the bloodstream. Sirs, this is systemic inflammatory response syndrome. This is a critical thing for nurses to recognize as the signs of sirs because treatment for sirs early before it gets on to sepsis saves lives. Catching infection and treating it at this point has a greater chance of success than waiting for full-blown sepsis, which actually can have up to a 60 percent mortality rate! It’s important to realize that temperature can be high or low and white blood cells can be high or low with sirs. Low temperatures or low white blood cells is actually a bad sign because it means the patient has used up all their defenses and their body has less ability to fight off the infection. Then if it progresses to sepsis, this is a severe systemic inflammatory response to infection. Sepsis can progress to septic shock which is shown by low blood pressure hypotension and organ failure. Mortality rate like I said is up to 60% and this usually results from organ failure related to little micro clots clogging the vascular beds of the organs. So take a few minutes here and pause and just think about some signs and symptoms of infection that you might see in your patients and then list them in your notes. So if we’re going to take this through the nursing process we realize that the first step in the nursing process is always assessment. We’re looking for normal pattern identification. Ask the normal measures taken by the patient to stay well. We want to look at risk identification and ask about exposure to illness from other family members, general health, smoking, alcohol, drug use, sexual practices, recent travel to foreign countries, chronic health conditions, any chemo, radiation immunosuppressant drugs that they might be taking. During the physical assessment perform a general inspection. We want to check vitals. Listen to lung sounds, bowel sounds, palpate lymph nodes. Remember that early recognition of sirs by a physical assessment is key to improving mortality rates. Diagnostics and lab procedures include a CBC. That’s a complete blood count. We want to look at the white blood cells and if it’s increased it’s called leukocytosis. Neutrophils will increase until they can’t be produced quick enough and then we get immature granulocyte releasing which are bands and this is where They get the term shift to the left. Remember that white blood cells can be elevated or decreased with infection. The UA/UC shows bladder infections, blood cultures check for bacteria in the blood and other Diagnostics That might be ordered are x-rays, CT scans, sputum culture, wound culture, fluid, stool or throat cultures as well. So after we assess we cluster or group the data and we form a nursing diagnosis. These are some possible nursing diagnosis for infection. Then we set the outcome and plan our nursing interventions. Here are some potential patient goals, you know for your patient they would need to be modified to your specific patient and then make them smart as well. So then we implement and again, that’s our action phase. And this is implementation of our nursing interventions. These can focus on health promotion like personal hygiene, protection of the skin and mucous membranes, rest and relaxation, nutrition and hydration, or immunization programs. Interventions could also focus on altered functions such as comfort measures, ambulating and positioning. Respiratory interventions, fever management, neutropenic precautions, antimicrobial therapy or prevention of infection spread are some other things we can focus on. And finally, we evaluate the interventions and whether or not the goals were met if they’re not met revise the plan of care. We want to look at the goals and interventions and fix them as we need to. This concludes our lecture on infection. Thank you for watching. And please be sure to watch the other lectures as well before class. Thanks and have a great day

All right.
There’s an old man, he’s got a safe, and he’s gone for a week. Let’s just work with that. – That’s good.
– Okay. – When’s he leaving?
– I don’t know. Great. Should we fix the cable? (BELL DINGS)HAN KI Who is i1′?Bayside here for your cable. HANK: My cable’s out. Yes, sir, I’m here to fix it. HANK: You need to fix it. -(GATE BUZZING)

I’d love to check it out. I bet you would. What’s that? Cable line comes in
through the living room. Perfect. You know my business better than me. I doubt that, you know? Okay, I think I know
what we’re dealing with here. I’ll be right back. How’s it looking? It works. Eh! Good job, son. You had a power surge. – It probably was just a power surge.
– Hmm. And don’t let anyone tell you
that you have nothing to offer. Because menial labor has its place. And you clearly know your trade. Oh sir, this is really too generous.
Thank you. I’ll let you get back to
your Hoarders marathon. Hoarders? I’m watching the Giants.
I got 50K on it. A little bet makes it a lot more fun,
don’t you think? (CHUCKLES) I wouldn’t know, sir. Well, you should be fine now,

a thousand cameras in this city, right? He checked in about 10:03. Let’s pull images from every camera
within five blocks of the station starting at 9:30, see if we can trace him back to a car,
and get a plate number. I’m on it. If we can teach him how to use the suit, then he can teach me how to

Time Lapse: Ants Carrying Fish Pellets Into the Nest

Time Lapse: Ants Carrying Fish Pellets Into the Nest


[Intro] Greetings, A.C. Family. We’ve got a special video for this week. And boy is it satisfying… Well, if you’re an ant-lover like me, that is. Because we received such a great response to our previous video, several months back, of our black crazy ants, the Dark Nights, drinking drops of honey, I wanted to do a similar video this week. A lot of you guy have commented saying watching the ants just doing their thing is super relaxing. So this week, something a little different: Our Golden Empire simply carrying fish food from a container to their nest. I know it’s odd, but this video will relax you and put you in an ‘ants trance’ as I also talk about the Golden Empire, their society, their behaviors and more. So keep on watching until the end. A.C. Family, let’s sit back and watch our Golden Empire and what the Koreans call a “mukbang” in this ant watching episode of the AntsCanada Ant Channel. ♪♪ Please subscribe to my channel and hit the bell icon. [whisper] Welcome to the AC family. [whisper] Bon appetit. Let’s start by laying down our small container of fish food right here, into the Hacienda Del Dorado. It isn’t long before a couple workers discover our food and inform the rest of the colony that they’ve discovered the goods. And so starts the hypnotic process of food collection. Let’s watch They say keeping tropical fish tanks Can lower people’s blood pressure and stress in my opinion and personal experience and watching has a similar relaxation effect We receive so many comments in our hidden videos every week which are very much like this video about how these time lapse and seemingly Monotonous activities of the Ants are Relaxing even proving therapeutic for some of our viewers dealing with anxiety ADD hypertension and other physical conditions If you’re like me, you could watch the ants do this for hours and hours and not get bored But I’ve time lapse this video. So you could watch the complete process in a shorter amount of time This is their normal speed But let’s get back to the timeline shall [we] I? Found that the Golden Empire our yellow crazy ants are quite easy to feed and they accept a wide range of different foods It’s no wonder this species [has] been so successful at invading most tropical parts of the world Dello Crazy ants are known as pan tropical meaning they can be found in all areas with a tropical [climate] We don’t exactly know for sure where this species originated But scientists suspect that they originated in West Africa and have migrated across seas to all other tropical areas Via human activities like Transport of Plants and goods they hitched rides on our boats and Cargo and the colonies were able to conquer countries and out-Compete and displays other ends There truly an empire that has succeeded as far as invasive and scope The species recently gained a lot of popularity due to a feature in a wildlife Documentary Which popularized yellow crazy ants as killers of native crabs on Christmas Island? Part of the reason for their success is not only due [to] their vivacious and ravenous nature But also due to the fact that they accept multiple Queens and colonies can fuse together creating huge Super colonies In fact the Golden Empire here is actually the result of three yellow crazy and colonies combined if you’re new [to] the channel Feel free to check out our yellow crazy ant playlist to watch how this colony our Golden Empire came to be Look at how the ants carry each individual piece Keep in mind those are heavy It would be comparable to us lifting boulders carrying it up over and down a vertical surface Then onto the nest the ants are super quick and effective I Just love watching the ants do this. It’s kind of like watching an hourglass, but Cooler It’s just amazing to think that the ants can carry out operations Like this in such a short amount of time and with the simplest of communication Ac family have any of you guys taking the time to watch ants work? What was it like? For me relaxation via observation of the ants working maybe one of the practical benefits of and keeping it Seems like the ants are carrying the food into a certain chamber underneath this driftwood as the ants carry the food back They lay down a pheromone trail all the way back into the nest To show ants leaving the nest exactly where to find the food this trail keeps on getting Reinforced as more and more ants return to the nest with food while also adding to that pheromonal trail the thicker that trail becomes The more eager the ants join in on the campaign and head out to bring back the fish food Want to hear something interesting Ac family so the ants themselves don’t have the ability to chew up this completely dry fish food These adult ants simply don’t have the chewing mouthparts Adult ants are able to consume mashes [and] liquids much easier than these super dry items like this fish food So I expect what these ends of the Golden empire are going to do is either one They’ll store the food in a very moist chamber of their nest until the fish food softens so they can eat it easier or two they feed it to their larvae the babies who actually do have the chewing mouth parts to eat Solid Foods and Then please from the chewed up pre processed foods that the larvae Regurgitate isn’t that neat this latter method. Which we know ants do means the babies eat first and then the adults Quite a different feeding system that seems to work for the [ends] Almost done now the entire process took just about half an hour to complete For those of you who would like to get into an keeping and there are bit squeamish about keeping live feeder insects like crickets mealworms Or roaches in your home if you can get your hands to feed from a high quality fish food like this You’re said your aunt’s will be able to get all the protein from the fish and other seafood ingredients in the fish food Okay, Ac family so you can truly [enjoy] this relaxing and watching experience I’m just going to leave you alone now for just a few minutes So you can watch the ants and get lost in an ant trance. I’ll be back in about three minutes. Enjoy and The final Crumbs are collected and the fish food supply is done So what happens now is the ants that come to the container and find out that there’s actually no food like the pheromone trail promised Simply return back to the nest but don’t leave a pheromone trail This causes the original pheromonal trail to weaken over time so less and less ants end up coming to the container in search of food And there you have So what do you say is that relaxing? Let me know if you like these kinds of videos or if you have any suggestions of other time lapses you guys would like to see Tell me in the comment section. Thanks for joining us for another week, Ac family. It’s [ant] love forever Okay, Ac family Ac in our colony Here’s your hidden video of this video non time next Honestly in my opinion the non time lapsed version is actually much more satisfying than this video It’s just longer and now it’s time for the Ac question of the week Last week we asked explain how any two living things plants or animals? benefit each other in the Hacienda Del Dorado congratulations to Jaden Seven six five four three two one clash of clans who correctly answered the aphids give the [ant] honey boo in exchange for protection Congratulations Jaden You just won a free Ac test to portal from our shop For this week’s a key question of the week we asked What does depend tropical mean leave your answer in the comments section and you could win a free ebook handbook from our shop Hope you can subscribe to the channel and give this video a [thumbs] up if you liked it Leave me a comment as I read through as many of them as I can and remember we upload a new Video every Saturday at eight a.m.. Eastern standard time Why? If it’s aunt love forever

On Safari: Ant Lions Of Death

On Safari: Ant Lions Of Death


let’s take a few minutes out of our hike today to learn about antlions you guys ever heard of antlions they probably have another name but that’s the only name I know of them or know for them what they are are little insects that burrow down into sand and they create like a like a funnel shape cavity that when ants come along the surface and they fall into this funnel they can’t get out because they try to curl up the sides and crawl up the sides and keep slipping down and slipping down kind of like that thing on dune for you old people and eventually the lens that comes up and grab them with these big pincers and pulls them under the sand and eats them it goes for ants now there are all kinds of other insects including like caterpillars and stuff but I just saw a few so I thought I’d share that with you because I knew we had not done in antlion video yet because I’ve been wanting to this is an ant line right here see this that’s his house and they’re right in the bottom of that is a little landline if you take a stick and make it just make a little vibration and stuff you’ll see him come up and try to grab the stick thinking that’s an ant maybe let’s even play like your ant trying to get out first something I’m shaking like crazy I’ve been hiking for hours alright that didn’t work so well that’s an inline nest – a longhouse or trap I guess we could call it that’s an antlion trap now the reason we’re doing this today because there’s one over here that’s the biggest one I’ve ever seen in my life I mean these things are all over the place even back home I’ve never seen a trout this big uh yeah Oh dad you’re selling it look at Johnny trap and antis fell and see if it gets out see it’s really hard from you doubt well it wasn’t hard for him we get out I’ll try that again he do I see a little red bug down in there – hmm he might already have been fed let’s catch an ant and bring them to another one I won’t do that you will get a different one come here nobody here’s a little one right here maybe he’s hungry else it may not have the ant anymore I don’t know there you go buddy that Marius watch it might be too big an ant for that nest he’s pretty big in me but he’s having a hard time getting out I guess the smaller ant probably wouldn’t get out he’s too big I guess I hope those aren’t chiggers right there are they I think they are there’s a goodness right there that’s right another ant that’s a man anybody all right try me up mister I’ll try them again there we go those answer too big I guess it needs a little tiny ones anyway you get an idea what they’re all about let’s go ahead and dig this one out so you can see what they look like yeah that’s great big ones I’ve never seen the nest that big I’m kind of interested in it another angular in the fall and they must be must get lost ants around here set all right let’s take em up thank you those might be chigger those little red bugs hope not because I’ve gotta have them all over me the best way to dig these up I found you have to kind of pull sand away from the center just like that now these things will make another nest pretty quick so they’re hard to see because they’re kind of weird-looking sand-colored then go back down under they can dig into the sand pretty easy what we’re going to do is we’re going to keep we know that’s the center so that’s where he’s at we’re going to dig this down a little bit I’m going a little stick you want to do some close-up work here you ready all right as ever a little weird bug I figured he’s probably got planning to eat here other areas right there look at him seeing gone down don’t wait for them to move you look just like the sand get not areas you see the pinchers on hopefully you can see him right here yeah see sudden Barry himself let me see if we catch them in our hand so he’d get a better idea what they look like that’s a good view of an antlion you see he’s a nice that one you see on his head he has little pinchers and that’s what he pulls the ants and other insects down into the nest he devours them underground that’s pretty neat all right we’ll put them back here make them a nice little spot to have another nest watch won’t take it long to get on the ground like you scared scared go the corner pound nothing he’s hiding we’re gonna just cover them up and go here you go buddy there if we come back here tomorrow we might in the morning but you’ll have a nice nest right here go ahead and circle it we’ll come back tomorrow maybe and look and see if he’s got 100 already I hope that was entertaining or at least educational I’ve been wanting to show you guys the antlions for a while because I think you’re kind of cool little creatures the only problem is is I’m really worried about this little reckless think of the cheaters hope not really cover wouldn’t if they are all right back to our hike [Music] [Music]

Invasion of the Yellow Crazy Ants!

Invasion of the Yellow Crazy Ants!


Earth’s ecosystems have always been changing,
with species mixing and mingling thanks to migrations, freak events, and slow creeping
expansions. But since we humans arrived on the scene, we’ve put things into fast-forward,
moving plants, animals, and other organisms around the globe — whether intentionally
or not. Once in a while, one of these transplants
might have an evolutionary quirk — like deadly poison, a lack of predators, or a voracious
appetite — that unexpectedly helps it dominate its new territory. Earthworms, for example,
were introduced into North America by European settlers and have been inching across the continent
ever since – tilling soil and improving crop yields as they go. But if a newcomer starts to harm us or a part
of the environment we care about, we’ll call it an “invasive species.” Technically-speaking,
humans aren’t “invasive,” because we don’t usually consider ourselves an ecological threat
to… ourselves. But other species certainly are. One way they
get our attention is by costing us money. A lot of money. The US spends billions of
dollars fighting invasive weeds like the pretty but pesky yellow rocket flower that chokes
fields and creeps onto golf courses and lawns. Other invaders wreak so much havoc on fragile
ecosystems that we can’t help but notice even if billions aren’t at stake. For example,
the yellow crazy ant – a likely native of Southeast Asia – has been eating many beloved
and endangered Australian creatures since its arrival several decades ago. These little
ants feast on nearly anything and everything in their path – insects, amphibians, birds,
small mammals, even the famous red crabs on Australia’s Christmas Island, which used to
keep the island’s undergrowth in check; without them, the ecosystem has veered into chaos. But noticing invasive species is easy – dealing
with them is the real challenge. When we brought rabbits to New Zealand for
food and fur, they escaped and bred like…well…rabbits, overrunning the country. So we introduced
ferrets to control the rabbits; but they too spread like wildfire, generally ignoring the
rabbits while gobbling up rare species like the now nearly-extinct kakapo. New Zealand
is still overrun by both furry fiends, and this is just one of many well-meaning attempts
at biological control that have ended in disaster. The best way to fight an invasion is to first
arm ourselves with knowledge: Instead of trying to kill Australia’s yellow crazy ants by just
spraying insecticide everywhere, we’ve learned that the best approach is a year-long multi-step
assault that specifically targets ant-riddled areas at the times when the egg-laying queens
are mature and susceptible to our treatments. Then we spread two kinds of bait for the workers
to bring back to the nest – one kills, and the other sterilizes the queens. Neither poison
is perfect, but executed together, they can knock out a whopping 99 percent of the population. But with many invasives, even 99% isn’t enough,
because it doesn’t remove whatever advantage gave the invaders an edge in the first place.
So unless we honest-to-goodness get rid of every reproductively active individual, eventually
they’ll return as vigorously as before, keeping us constantly on our toes. We really just need to stop moving potential
troublemakers around in the first place, leaving bunnies where they belong and making sure
ants and earthworms don’t stow away in ships, cars, or excavators. But in a modern, globalized
world, this is easier said than done. For those species that we do accidentally (or
intentionally) let loose only to see them spread wildly out of control, our best hope
is to learn as much as we can about their habits and their biology – only then do we
have a chance of keeping their harmful “ant”-ics at bay.

Spray foam insulation nightmare: What can happen if it’s not installed correctly (CBC Marketplace)

Spray foam insulation nightmare: What can happen if it’s not installed correctly (CBC Marketplace)


(♪♪)>>Tom: This week on “Marketplace”.>>I’m afraid for the children and, you know, what they’ve been exposed to.>>Tom: Insulation nightmares.>>I think we’ve got what we need for the lab.>>Tom: It’s a popular energy saver.>>When It’s installed properly, it’s really — it’s a bullet proof product.>>It’s gotta come out, the foam’s gotta come out.>>Tom: That could put you out of house and home …>>You’re playing kind of a game of Russian Roulette with this.>>Tom: And transform your life into a renovation horror story. (♪♪)>>Tom: It’s a scorching June day. We’re driving into the Caledon Hills, north of Toronto, and into a nightmare. The house of their dreams, now haunted. The owners living in a camper steps from the front door. This is a refuge for Robert and Sonia Franceschini and their two kids. I guess it won’t be a long tour.>>No probably not. So this is where we’ve been living.>>Tom: Wow, yeah.>>This is the trailer. The kitchenette area.>>Tom: Right. So you’ve got two young children. Are they asking lots of questions about why are we in here?>>We try not to talk too much in front of them so they don’t get worried or frightened.>>Tom: What could be so frightening? Wow, big house. Nice. It’s just 14 years old he says. 3000 square feet. Mortgage free. But right now, he couldn’t sell it if he tried. The reason? There’s something in the air. Ok the bedroom. Oh yeah, I can smell that.>>Oh, yeah.>>Tom: Geez.>>It’s pretty bad.>>Tom: Pretty strong, yeah. foul. Like bad fish smell.>>The hotter it gets the more, the more it smells.>>Tom: Right.>>The more it smells.>>Tom: And if you stay in here long, what happens?>>Well, you’ll see within the first five minutes you’ll probably start getting a headache.>>Tom: Actually I’m getting a headache now, honest to God. I’m feeling something here. Yeah, it’s quite, uh, it’s insidious. It’s not just the bad smell that’s made their home unliveable.>>Well I started feeling like excruciating pain, joint pain, in the knees and I had swelling in my legs and my feet. And, uh, I just looked at Robert and I said, Robert, I think I need to go to the hospital.>>Tom: They feel as if their house is attacking them. The trouble started this spring they say. Just days after their attic was treated with spray foam insulation. Did you call the company and explain you were having problems? What did they do?>>I brought them up to the bedroom where the main problem was and they said they really couldn’t smell anything. And I was flabbergasted.>>Tom: So what did you think when the company said we don’t smell anything?>>Well, I knew exactly where this was gonna go. And this is why were still here two months later.>>Tom: You heard right. On our visit, they’d been out of their home for two months. When she has to go inside, Sonia wears a mask.>>We thought we were doing something to improve our home and instead they basically destroyed my home. They ruined it. We can’t live in it anymore.>Tom: Not the kind of testimonial the spray foam industry wants to hear. Over the past decade, it’s become the hottest trend in Canadian home insulation. The industry is growing by 30% every year. Why the boom? High heating costs, government tax credits.>>They introduced spray foam which I absolutely love.>>Tom: And those home reno shows. (♪♪)>>Tom: The spray foamer those stars rely on?>>Sorry I can’t remember all the shows, there’s so many.>>Tom: Alex Schuts, who started his own business while in high school.>>I’ve been doing it 22 years. I live and breathe insulation. It’s good for the environment because we save on burning of fossil fuels. It doesn’t let drafts through. when It’s installed properly It’s really a bullet proof product, right.>>Tom: Hmm, when it’s installed properly?>>It’s not simple, and you don’t just pick up the gun and start spraying.>>Tom: Nope, it’s more like a science project right in your home. The sprayer is mixing two sets of serious chemicals he’s specially trained to handle. The conditions have to be just right. And the foam has to be sprayed in thin layers, so it can cure allowing the chemicals to stabilize. It’s sophisticated stuff that promises an energy efficient home. And Alex Schuts says it works that way almost every time.>>There’s a lot of foam being sprayed, there’s a lot of happy customers.>>Tom: In fact, the Franceschini’s were happy when they had a family property spray foamed this past spring. But after their attic job at home, Sonia says not only did she feel ill, she says her daughter broke out in rashes.>>I’m afraid for the children and, you know, what they’ve been exposed to and, um, you know, is there going to be any long term effects to what they’ve been exposed to and it’s just really upsetting. (♪♪)>>Tom: Fear, stress, uncertainty for two months. Time to find out if this foam has taken possession of their home. We call in Frank Haverkate. Frank, how are you doing.>>Hi Tom, how are you, nice to see you.>>Tom: He’s a certified indoor air quality specialist. He’s trying to figure out what chemicals might be floating around.>>Let’s take a reading in the bedroom where we smell odours.>>Tom: He pulls out his computerized air detector. And the small tins gather air samples for later.>>All these samples are going to be here for 48 hours.>>Tom: Then we enter the belly of the beast. If an attic can be a belly.>>So we just want to get a cutaway of the inside of the core closest to the bottom.>>Tom: Frank also wants to test a foam sample.>>I’m not wearing any nitral gloves or any gloves because I don’t want the chemicals from the nitral affecting the sample that I’m cutting.>>Tom: Could this be what’s giving off bad fumes?>>I don’t know if you want to take a sniff of that but it has a pretty good odour to it.>>Tom: Mmm, it’s that fishy odour again, right? Same smell from the bedroom. we’re right above the bedroom, right here.>>I think we’ve got what we need for the lab.>>Tom: Excellent.>>Great. Let’s get out of this sauna.>>Tom: I agree with you. There is no graceful way to do this. Foam samples in hand, Frank heads out, and offers a few last minute instructions to the family.>>Stay out of the bedroom. just leave everything the way it is I’ll be back in a couple of days to pick it up.>>Tom: The Franceschini’s may feel alone in this horror show.>>We all felt burning like ammonia.>>Tom: Turns out they’re not.>>We live with a nightmare still.>>Tom: Tales from the deep south. Reveal more foam invasions.>>You’re playing kind of a game of russian roulette with this. (♪♪) (♪♪)>>Tom: we’re investigating a renovation horror story, and our journey into the dark side of spray foam has taken us south to the sunshine state.>>Tonight action 9 exposes a growing threat to local home owners.>>Tom: Where we heard more reports of foam invasions.>>My heart just started racing and racing, and I was hyperventilating and I fell to the ground.>>Tom: I’m in Kissimi, Florida, an Orlando suburb. on the way to meet Joan and Mike Roth. Driven from their house by spray foam three years ago. So your trailer was over here?>>Yes, it was over on thisre? side. That was a nightmare. that’s how we list everything that happened to us, just the overall category, we call it a nightmare.>>We all felt burning like ammonia, it was an awful experience.>>This just gives you a sense of how deep this is.>>Tom: Their home video is now the Rothi’s personal horror flick. It started when they spray foamed the attic. They wanted to cut their energy costs. It was the cost of their health and home that blindsided them.>>We say before the foam and after the foam. I mean, It’s changed our lives.>>Tom: First the installer and manufacturer claimed there were no problems. Then tried some repairs. nothing worked.>>So I actually got on the phone and called remediation companies,companies that take out asbestos, and that type of thing, deal with mould problems; none of them had a protocol for spray foam. Nobody was going to touch it.>>Tom: What the Roths were learning is that North American spray foam industry has no official guidelines for taking out a bad job.>>So we said we’re going to have to pull the sheeting off the roof, pull the whole thing off, and have someone mechanically go in and scrape every piece of wood and every piece of drywall and take it and throw it away.>>Tom: And how did that go?>>What was it, 16 days?>>Sixteen days it took.>>Finally they got 90-some per cent of it out.>>Tom: Safely locked away in the garage, Mike is keeping some relics from their ordeal. Looks like candy.>>It does not smell like candy.>>Tom: Oh, yeah, yeah, sort of a fishy smell. There are other reminders that are far more upsetting. Their son Julian has suffered from asthma and joint pain ever since, reacts to the chlorine in the pool. But the Roths say he was fine until the morning the spraying started, when he was sleeping.>>This is Julian’s bedroom. this is where they sprayed first. I’m still upset when I think about that crucial time when he was in the room when they were spraying right over his bedroom. Makes me sick. Makes me sick to think about.>>Tom: In fact, the whole family was inside that day.>>They didn’t say anything about leaving the house and here they are spraying these chemicals up there and we’re still in the house.>>Tom: Health issues. Smelly foam. Living in a trailer. The Roth’s story is eerily similar to our Canadian case. As spray foam’s popularity has spread, so have more troubling stories.>>You’re playing kind of a game of Russian roulette with this.>>Tom: Bernie Bloom is a kind of foam buster.>>It doesn’t matter if you did it right twenty times in a row, the twenty first home might be different.>>Tom: People such as Bernie are in demand across the U.s. they’re expert advisors for a number of class action lawsuits currently underway. a leading indoor air scientist for 40 years, he’s involved with dozens of bad spray foam issues, six of them here in Florida.>>We have more and more houses being sprayed. I expect there’s going to be more, not fewer, problems.>>Tom: The man who helped design ventilation systems for the international space station believes spray foam is a formula for trouble.>>The foam itself is manufactured in the house, not in a factory. If you spray it too thick and it gets too hot, then the reactions that happen are not what was designed in the factory or in the laboratory. You got a runaway reaction.>>Tom: So that fishy smell? Bernie says it means the chemicals in the foam weren’t mixed right and didn’t stabilize.>>When it works, it does fine. When it doesn’t work, and if you’re in the house, you can become chemically sensitized which is a dreadful condition.>>Tom: Bernie’s not a doctor. but experience tells him that’s what happened to the Roths. Why would they be there or why wouldn’t they be told to leave?>>If you tell somebody, um, we’re going to spray the stuff, It’s great stuff, but we want you not to be in the house for a day or two. which is conventional industry Internal guidance, some people are going to ask, why? Is there something wrong? Is it toxic?>>Tom: The day their attic was sprayed in Caledon, the Franceschinis weren’t worried about the foam because they say, they didn’t know about staying out of the house.>>Most of the time we were out here while they were spraying. If we needed something we’d run in the house and get it. When the salesman was here he may have mentioned it, but I don’t recall. But out of all pamphlets, paperwork I got, or all my quotes, nothing in there that says I should have stayed out of the house, cause that would have stuck in my head.>>Tom: And here’s their job quote. Nothing about staying out of the house. Nothing in the company brochures either. Meantime, It’s been more than three months since they’ve had a family meal in their dining room or kitchen.>>What took you so long?>>Oh, please.>>Tom: Can it really be that bad in the house so long after the job was done? (♪♪)>>Tom: Oh, yeah. It’s still there. There’s still that fishy smell.>>It’s still off gassing.>>Tom: Yeah, you can still smell it.>>We’ll turn that fan on, ventilate the whole house, open up all the windows, shut it down and it’s right back.>>Tom: Remember — we tested the bad air in the master bedroom and the foam above it. Now Frank Haverkate is back with some unsettling results. The air samples reveal a laundry list of chemicals.>>In a nutshell you’ve got some Toluene issues, you’ve got MEK issues.>>Tom: Some of those things can be linked to cancer.>>Ethylbenzene.>>Tom: Frank believes the spray foam job’s to blame but can’t conclusively prove it. Now for the foam results.>>One of the surprising things is we found formaldehyde. Now, it’s –>>Tom: Formaldehyde?. We’re surprised. The manufacturer of the Franceschini’s foam says their insulation doesn’t contain formaldehyde or similar compounds.>>Again, they’re low levels but, uh, it really shouldn’t be there.>>Tom: Frank thinks It’s the installation job gone wrong, creating new, dangerous chemicals. What do you think about what you’re hearing.>>Needless to say It’s scary.>>Tom: You scared?>>Yes, very much so.>>Tom: So what’s your advice to them?>>You’re gonna have to get the product removed.>>Tom: Desperate times, desperate measures.>>Well, you can only stay in a trailer for so long.>>Tom: you’re about to see one extreme makeover. (♪♪) (♪♪) (♪♪)>>Tom: The Franchini’s are tired of trailer living.>>Go into our room, go. (♪♪)>>Tom: Tired of being spooked by the spray foam in their attic.>>I’m still in disbelief. I can’t believe that somebody would do this to a family and not want to take ownership for what they did.>>I need to get back into my house.>>Tom: And they’re tired of searching for answers. The foam manufacturer had the air and the foam tested and said its product wasn’t causing problems. Then, an independent group determined a section of foam was too thick and emitting chemicals. The manufacturer eventually agreed. the family has heard enough.>>It’s gotta come out, the foam’s gotta come out. (♪♪)>>It’s gotta come right out. Yep.>>Tom: Removing bad foam is what Alex Schuts is up to today.>>Mainly on this side. This side too. It’s the middle section that’s the worst.>>Tom: The stuff his man sprayed isn’t making anyone sick and it doesn’t stink but It’s cracking and peeling.>>Never seen it this thick. This is the worst I’ve ever. seen, Tom. It’s terrible.>>Tom: Yes. TV’s most famous foam sprayer doesn’t always get it right and the industry agrees not every job is perfect.>>I hate the fact that it’s happening, but we’re here, we’re here to fix it. And it doesn’t cost the customer any money.>>Tom: How common is it for installers to have to take out foam?>>It’s rare. It’s happening more now than probably in the past because there’s a lot more newer contractors out there.>>Tom: In your view, then, if an installer gets it wrong, are they obliged to fix it do you think?>>Damn right. Yeah, yeah. If you’re not doing what you’re supposed to be doing, fix it.>>Tom: So we’re hitting the road to Huntsville, Ontario, to talk to the company that spray foamed the Franceschini’s attic. A family business called Thermoseal Insulation. Richard Clement is the owner. So what do we have here?>>So this is the chemical, the two chemicals go together. If It’s not sprayed correctly it certainly could be a problem.>>Tom: he’s been in the business for decades. He figures the company’s done about 15,000 spray foam jobs, and says it’s their first case like this.>>I was in the bedroom, like the master bedroom upstairs.>>Yes.>>Tom: That’s where I got that smell. Did your folks go up there when they first visited the house?>>When they went there and couldn’t, they couldn’t detect it — I should qualify that,ct that they did smell, but it’s the smell they are accustomed to with a fresh application of polyurethane foam. They didn’t detect a fishy smell as the homeowner did.>>Tom: Richard says consultants told him only about 1% of the foam was bad.>>Tom: So why didn’t your company take out that foam?>>We offered to take out that foam. The homeowner decided that he wanted to have the entire attic area, 13 or 1400 square feet removed and that, in our opinion, and every other professional’s opinion was — unrealistic and unwarranted.>>Tom: Given that um, the wife got sick, days after it happened, can you understand why they’d probably want to get rid of it, get it out of their house?>>We’re sorry that the folks got sick but we don’t feel that it’s necessarily anything to do with the foam.>>Tom: He also disagrees with the family’s claim they weren’t warned about staying out of the house. There are guidelines that say in a residence the family shouldn’t be in the house for 24 hours.>>He was told that. he was told that by three different people from our company.>>Tom: Is there a reason it’s not on like the quote or the contract or anything like that written down?>>Since that incident we have put it in writing.>>Tom: Here’s Thermoseal’s new contract. By signing, the homeowner acknowledges: I have been informed of the health hazards and. I am not to occupy my residence for a period of one day (24 hours) after spray foam is installed. Spray foam is popular but Clements suggests it’s not always the best insulation choice.>>Tom: You try to talk people out of it.>>Yes, we do. So maybe people are using it too much in their houses?>>in some of the places we’re working it’s become the standard and there are, I think there are better applications out there.>>Tom: So if you’re thinking of Insulating, learn the risks, and benefits, of all kinds of insulation. If you pick spray foam, make sure the installer is certified and experienced. Get a guarantee of foam removal in writing, in case things go wrong. And stay away for at least a day. (♪♪)>>Tom: As for the Franceschinis, the disturbing tale of the house in the Caledon Hills has reached the end of the road. Are they still in the trailer? They got some relief? Problem solved? Trying to find out.>>Well, a you can come in and have a look. As far as you can see, if you look up there, the whole roof was removed.>>Tom: they’ve actually blown the lid off their home>>The only way to remove the foam for safety reasons was to Remove the whole roof.>>Tom: This renovation horror story ends with a domestic decapitation. Did they take it off in one piece?>>Yeah, the ceiling is still underneath. Well, we can see from the front. (♪♪)>>Tom: It’s almost like a skeleton in a way, right? Its finally stopped haunting you.>>Thank God that it’s outta my house and we don’t have to breath any of this anymore.>>Tom: After this long nightmare and its dramatic end Robert Franceschni is waking up to a new realization. He has to think about insulation again.>>And I have to be honest with you, I haven’t gotten to That stage yet on what to do. I guess it would be really stupid to try and re-spray foam. So… (♪♪)

Sunflower Star Imperiled by Sea Star Wasting Epidemic

Sunflower Star Imperiled by Sea Star Wasting Epidemic


[Narrator] There’s an epidemic
in the ocean. Since 2013, a viral disease has been
turning sea stars in the Northeast Pacific into melted piles of goo. Of the 20 or so
species of sea stars affected by the virus, one of the hardest hit were sunflower stars.
Until now, we haven’t known just how bad the decline was. But new research
has begun to reveal the longer term continental scale impact of the
epidemic on certain species. Scientists in the US are now suggesting
we formally list the once common sunflower star as an endangered species. Trained citizen science divers from
California to Alaska counted sunflower stars on over 11,000 dives,
while scientific divers from the Hakai Institute carried out more detailed
surveys on the BC Central Coast. When they looked at all the data,
scientists noticed something in common where they saw outbreaks of the
virus—anomalously warm water. We still don’t know how these warm
water anomalies and the virus interact. But researchers say these warmer than
normal water temperatures were related to dramatic sea star declines. While divers
can patrol waters near the surface, we didn’t know whether sunflower sea stars
might have found refuge at deeper depths. But thousands of NOAA bottom trawl
surveys have revealed that when it comes to sunflower stars, the
disease didn’t stay in the shallows. For example, data from Washington State
shows a crash in populations in both shallow nearshore and deep offshore
environments after the epidemic began in 2013. Data from other areas on the coast
are similar. With population declines of as much as 80 to 100% in areas across the
3,000 kilometers from Alaska to California. Sea stars may appear to be the passive
bottom dwellers of the deep blue, but they are actually pivotal predators
in this ecosystem. The loss of sunflower stars is already
showing massive repercussions on ocean food webs and kelp forest
habitats up and down the coast. One thing is for sure, scientists and
recreational divers alike will be checking to see when, or if,
the sea stars recover.
