Thermoregulatory behavior and diel activity of yearling winter flounder, Pseudopleuronectes americanus (Walbaum)

SynopsisSixteen yearling winter flounder, tested individually for 3-day periods in electronic shuttleboxes, voluntarily occupied an 8–27°C range of temperature, with a modal final thermal preferendum of 18.5°C (mean 18.7°C, median 19°C, midpoint 17.

Heat capacity of fcc calcium

AbstractThe lattice entropy derived from the measured heat capacity at intermediate and high temperatures is analyzed to yield a weakly temperature dependent entropy Debye temperature. An unusual temperature dependence of this quantity may be a sign of error in the heat capacity data.

Compressibilities of cyclohexane and toluene mixtures at various temperatures

AbstractThe isothermal compressibilities T for cyclohexane+toluene mixtures at 25, 35, 45 and 60°C have been determined by direct piezometric measurement. By combining our results with supplementary literature data, we have calculated the isentropic compressibility S.

A soil lysimeter system with water table and temperature control

SummaryA soil lysimeter system especially built for Histosoils, has been in operation since 1974. The individual cell has preset levels of water table and simulated temperature gradients. The system has functioned satisfactory in studies on plant-soil relationships.

Influence of temperature and relative humidity on survival and fecundity ofPauridia peregrina, a parasite of mealybugs and its interactions withPlanococcus citri

AbstractSome biological aspects of the encyrtid parasitePauridia peregrina Timberlake were studied. Non-ovipositing ♀♀ lived longer than ovipositing ♀♀. Parasite survival was strongly affected by relative humidity. Females survived best at 21.5? and 92% r.h.

Ionization constants of aqueous ammonia from 25 to 250°C and to 2000 bar

AbstractThe ionization constant of ammonia has been determined by conductivity measurements and found to vary from 1.77×10–5 at 25°C to 1.3×10–6mol-kg–1 at 250°C.

Correlation of blood temperature fluctuations with blood pressure waves

SummaryConstant blood temperature in the pulmonary artery is assumed when the thermal dilution method is used for cardiac output determination. In some cases, however, slow temperature fluctuations (2–6 cycles per min.) occur in arterial and venous blood and interfere in the measurement.

Effect of mulches on bacterial populations and enzyme activity in soil and vegetable yields

SummaryMulches in five combinations of clear plastic, black plastic, and undecomposed leaves covered by or on top of black or clear plastic film to modify soil temperature, were used to study the enzyme activity of the soil and numbers of bacteria able to produce degradative enzymes.
