Calorimetric determination of thermodynamic quantities for chemical reactions in the system CO2?NaOH?H2O from 225 to 325°C

AbstractThe phase equilibrium CO2(g)=CO2(aq) and the aqueous reactions CO32–+H+=HCO3–, HCO3–+H+=CO2(aq)+H2O, and Na++CO32–=NaCO3– were studied from 225 to 325°C using a flow calorimetric technique.

Soil surface CO2 flux in a Minnesota peatland

AbstractSoil surface CO2 flux was measured in hollow and hummock microhabitats in a peatland in north central Minnesota from June to October in 1991. We used a closed infrared gas exchange system to measure soil CO2 flux. The rates of CO2 evolution from hummocks (9.8 ? 3.

Effects of bupropion on core body temperature of mice

AbstractThe effects of bupropion on core body temperature of intact or reserpinized mice were studied. Intraperitoneal (IP) administration of bupropion to mice induced a dose-dependent hypothermia.

Local variation in diapause characteristics of Tetranychus urticae Koch (Acarina: Tetranychidae)

SummaryDiapause characteristics of nine local populations of Tetranychus urticae Koch (Acarina: Tetranychidae) occurring on rose in central Japan were investigated. The percentage of females that entered diapause at 18° C and 9L: 15D photoperiod ranged between 0 and 77%.

Effect of high root temperature on Bradyrhizobium-peanut symbiosis

AbstractThree strains of Bradyrhizobium, 280A, 2209A and 32H1, that nodulated peanuts (Arachis hypogaea L.), were tested for their ability to grow and survive at elevated temperatures of up to 42°C in laboratory culture.

The study of diffusion processes in the thermodesorption results

AbstractA consecutive model of surface reaction, consisting of two steps (desorption and diffusion) was applied. It was concluded that diffusion modifies the temperature programmed desorption spectra, although the single peak curves appear.

Body temperature and metabolic rate during natural hypothermia in endotherms

AbstractDuring daily torpor and hibernation metabolic rate is reduced to a fraction of the euthermic metabolic rate. This reduction is commonly explained by temperature effects on biochemical reactions, as described by Q10 effects or Arrhenius plots.
