Determining the temperature dependence of soil respiration is needed to test predictive models such as Arrhenius-like functions and macro-molecular rate theory (MMRT). We tested a method for rapid measurement of respiration using a temperature gradient block, cooled at one end (similar to 2 degrees...
Surface soil-heat fluxes were determined for 6 days in a field of Avondale loam using the null-alignment method, the combination method, and four variations of the temperature gradient method with thermal conductivities computed from the... BA Kimball,RD Jackson,FS Nakayama,... - 《Soil Science...
In the second method, there is a temperature gradient on the bar that makes it impossible to use the data obtained directly by the strain gauges to describe the mechanical properties of rock, but the SHPB device with simple structure is retained. 3.1. Variation of bar parameters with ...
Their study documented the establishment of a negative temperature gradient in the crop, with air temperature being coldest in the upper canopy. While the thermocouples used in their study had a reported accuracy of 0.05 °C, the variable spacing limited the resolution of vertical temperature ...
Thinking about the thermal gradient from shell to center of egg, it would make sense that cooking an egg starting in cold water would result in a more uniform doneness. The delta between the center and outer temperatures will be smaller, meaning that the outer portion won’t be as overcooke...
Soils from diverse management systems were exposed to the same experimental condition (temperature gradient, moisture), which allowed us to compare relative response of diverse management practices to potential warming. Increasing crop diversity by including pea in crop rotation appears to reduce SOC ...
RDA, a widely used constrained gradient analysis technique, is an effective way to tackle this issue79,80. In this study, we used RDA to explore the contributions of seasonal temperatures to the variations in modern PFT score data before reconstructions. Several critical parameters were calculated,...

The circles filled with different colors represent PBs with a gradient of distinct thermostabilities. The circle with a dotted line represents the nucleolus. The most thermostable PB persists in all temperatures, whereas the less thermostable ones form only in lower temperatures. As a result, ...
