Murine typhus rickettsiae injected intraperitoneally in mice of the dba strain caused a uniformly fatal rickettsial peritonitis if the animals were kept at a room temperature ranging from 65–73°F. or from 70–80°F. With an environmental temperature range of 85–98°F., a mortality of less than 25 per cent was observed. By utilizing different strains of mice and controlling the environmental temperature, conditions may be created under which murine typhus will have any desired degree of mortality. Such conditions have obvious advantages for the evaluation of therapeutic measures in typhus infection.

The purpose of this study was to investigate the effects of environmental temperature conditions and running duration on the mechanical property changes of shoes having ethylene vinyl acetate (EVA) midsoles. Midsole temperature changes were obtained for a series of 40-min runs (2 subjects, 7 runs) under various seasonal environmental temperature conditions (winter 5–15 °C, summer 45–55 °C) for a normal shoe (35 durometers, Shore A). Midsole temperatures increased an average of 8 °C during the initial 15–20 min of running and were followed by relatively constant temperatures. Subsequently, the mechanical properties of soft (25 durometers), moderate (35 durometers), and firm (41 durometers) midsole shoes were evaluated using an impact tester over similar temperature ranges. With increasing temperature, peak deceleration and energy absorption decreased, and the times to peak deceleration and peak deformation increased. The results suggest that ordinary running shoes with moderate midsole hardness probably provide inadequate cushioning in cold environments and inadequate rearfoot control in hot environments.

Moisture handling property of fabric has been regarded as a major factor in the comfort performance of clothing in normal use. Especially in different environmental temperature conditions, fabric’s moisture comfort property has different manifestation. In this paper, a series of experiments and analyses were performed on studying the dynamic moisture transferring procedure and evaluating moisture comfort property of fabric under different environmental temperature conditions. By Textile-Microclimate Measuring Instrument, five different fiber fabrics’ dynamic experiments were performed in different environmental temperature conditions. By measuring the real time changes of relative humidity in inner and outer surfaces of test fabrics, fabrics’ dynamic comprehensive index was obtained to characterize fabrics’ dynamic moisture comfort property under different temperature conditions. Finally, grey system theory was introduced to establish models that could describe the relationship between the static parameters and the dynamic comprehensive index. The grey interrelationship analysis was performed firstly to find out the static parameters that have high degree of association with dynamic comprehensive index. And then the grey mathematics modeling method was performed to establish models predicting the dynamic comprehensive index using static parameters. In three different temperature conditions, three different prediction models were built and high predictive precision was obtained.

The shrinkage temperature (Ts) in 0'9% saline of the collagen of a number of marine and terrestrial gastropods living in a wide range of temperature conditions has been examined and found to correlate with the environmental temperature of the source, i.e. the higher this environmental temperature the higher is Ts.

Moisture handling property of clothes using fiber is an important factor determininig clothes comfort property. In this paper, the moisture comfort property of fine denier polypropylene fiber fabric in different environmental temperature conditions was studied. By Textile-Microclimate Measuring Instrument, five kinds of test fabrics' dynamic experiments were performed in four different environmental temperature conditions. And fabrics' dynamic comprehensive index was obtained to characterize fabrics' dynamic moisture comfort property. Then, grey system theory was introduced to establish models that could describe the relationship between the static parameters and the dynamic comprehensive index. Results show that the dynamic moisture comfort property of fine denier polypropylene fiber fabric is the best. And fabrics with lower thickness, lower weight, and higher vertical wicking height will be more moisture-comfortable.
