1. The experiments of Madsen and Watabiki on the effect of temperature on the phagocytosis of bacteria are discussed and a new analysis of their curves is given, showing that the rate of phagocytosis is very nearly a logarithmic function of the temperature from 0 degrees to 35 degrees C.; i.e., Q(10) is constant over that range and is equal to 2.0. 2. New experiments are reported on the effect ...

number of bacteria ingested at the close of the experlment(instead of the maximum number of bacteria present, which, one is led to infer, was larger than A even at the higher temperatures) and x equal, as usual, to the number of bacteria ingested in time, T. Considering their method of analysis it is not surprising that they found it impossible to calculate the temperature coefficient of phago•...

Watershed modeling has become an important tool for researchers. Modeling nitrate transport within drainage networks requires quantifying the denitrification within the sediments in canals and streams. In a previous study, several of the authors developed an equation using a term called a mass transfer coefficient to mathematically describe sediment denitrification. This equation takes into acc...

polymer-graphite powder composite behaves as a low-conductive material which can be used as an automatic fuse for adhesive connector in electrical circuits. the conductivity of this composite, below its transition temperature, tt, depends on concentration of carbon powder, slowly decreases as the temperature increases. meanwhile, the electrical resistivity of this material in transition tempera...
