Practical and reliable TEWL, evaporation and permeability measurements. The VapoMeter is the only fully portable instrument available for the measurement of TEWL (transepidermal water loss) values and evaporation rates. TEWL is a well known indicator of the skin's barrier function. The VapoMeter is battery-operated and portable. This offers great freedom of movement and the possibility of measuring difficult areas.
How to Cook Beef Tripe. Beef tripe is a type of food derived from the lining of one of a cow's four stomach chambers. Tripe (which can come from many other animals, but usually hoofed farm animals) is eaten all over the world as an important ingredient in many local cuisines.
Beef Tripe tastes great when cooked properly and mixed with the right ingredients. This Easy Callos Recipe is a good example, aside from Kare-kare. I like this recipe because it is straightforward and makes use of ingredients that we can easily find in the supermarket. I started out by cleaning the beef tripe.
