Future Apple and Samsung phones may be waterproof.
Following on from this story about a new spray to keep your mobile phone water proof, it seems another company may be going straight to the source, and lining up deals with Apple and Samsung to coat all new phones in a water proof coating.
The company HzO has come up with a competing product called WaterBlock, which it claims “protects your devices on a molecular scale, so you can breathe easy”.
According to a report on PocketLint:

The company is hoping to sign big deals with all leading manufacturers. A spokesman for the company told Pocket-lint that it is in the process of signing up a major smartphone partner and a headphones maker in the very near future.
The plan for headphones is that they wouldn’t be damaged by sweat when running or water when swimming.
“We showed the Samsung Chairman the technology with a Samsung Galaxy S that we had coated with HZO and he couldn’t believe his eyes,” a representative of the company told us. “Samsung is really excited by the tech.”
The company has told us that they are also talking to Apple as well, hoping to be able to let Apple make the iPhone 5 waterproof.
“We expect HZO to be in next season’s phones,” HZO told Pocket-lint rather confidently.


Seems that NeverWet, which I also wrote about recently, will have some competition.
Good. The more, the better!

The Tangential: Things To Do With Your Drugs Other Than Use Them

thetangential:

Want to quit using drugs but not sure what to do with all those drugs? Here are some ideas:

• Use them as inspiration for a collection of “single experience fragrances,” a la the early days of Demeter cologne. They haven’t released “Weed Jar” or “Ground Adderall,” last time I checked.

Why do infants and young children have more ear problems than adults? The eustachian tube, which connects the nasopharynx to the middle ear, is proportionately shorter, wider, and more horizontal in infants than in older children or adults.
During sucking, yawning, and other movements, the tube opens for milliseconds, allowing free passage of air between the nasopharynx and the middle ear. This predisposes young children to development of otitis media or middle ear infections.

ER in upcountry

It is more of OT medical services, mostly non-emergency cases.

There is indeed some more-or-less emergency like acute MI.

At this time, I’ve got a lot of chance to do traumatic wound stitching. — There are alcoholics and accident victims with wounds like head injury…

Calculating sample size in community research

I haven’t read this topic thoroughly yet, but I have been guided to use sample size calculation by Krejcie and Morgan’s work.

In short, I am working in a village of about 300 people, so I need to collect at least 169 samples.

In short,

100 — sample 80

400 — sample 198

1 400 — sample 302

10 000 — sample 384


WHEN TO DITCH YOUR DOCTOR

Blood Transfusion Dose
The magic number to remember is 4. 
4ml/kg of packed red blood cells will give you an increase of about 1g/L of haemoglobin. 
For example a 9 kg child with an HB of 5g/L will need 180ml of red cells to reach an HB of 10. (9kg X 4ml X 5g/L = 180ml)
PS - You can use this formula for adults too.
