Giardia intestinalis (aka: Giardia duodenalis, Giardia lamblia) is a common, microscopic (intestinal) parasite that commonly affects humans, dogs, and cats. Common signs and symptoms of Giardia infection (in both humans and pets) are diarrhea, gas, abdominal discomfort, nausea, and vomiting.
Thermal conductivity 1 Thermal conductivity In physics, thermal conductivity, is the, property of a material's ability to conduct heat. It appears primarily inFourier's Law for heat conduction.hermal conductivity 2. Definitions The reciprocal of thermal conductivity is thermal resistivity, usually measured in kelvin-meters per watt (KÂ·mÂ·W â1).When dealing with a known amount of material, its thermal conductance and the reciprocal property, thermalresistance, can be described.
Glass is far inferior to paper, plastic and Styrofoam in terms of insulation. Thermal conductivity in terms of BTU/(feet - hour - degrees F) is 1.82 for glass, 0.09 for paper, 0.06 for Styrofoam. The conductivity of plastics varies depending on the materials: for polypropylene and polycarbonate, the thermal conductivity values are 0.69 and 0.35, respectively.
