Temperature accuracy and temperature gradients in solution-state NMR spectrometers.

In solution-state NMR spectrometers, there is a systematic deviation between the temperature of the sample and the temperature reported by the spectrometer. In addition, temperature gradients are often present in the sample. The size of both the temperature deviations and the temperature gradients depends on several factors, including the temperature, the flow rate of the heating/cooling gas, a...

Temperature gradients in the rabbit eye.

Measurements of the temperature of the various parts of the rabbit eye under both local and general Nembutal anesthesia were made ivith the thermistor as the temperature-measuring device at a room temperature of 22 to 24° C, and a relative humidity of 33 to 53 per cent. The equipment and its calibration are described in detail. The existence of a temperature difference of 6° C. (corrected for t...

Relationship of base temperature to development of winter wheat

Development of wheat (Triticum spp.) is primary driven by temperature, but is also affected by other factors such as vernalization and photoperiod. Crop growth and development are often described in terms of calendar days. However, determining the development in terms of thermal time or physiological time is more accurate because it is an accumulation of the caloric energy needed for the o...

Sludge (de)flocculation Dynamics in Secondary Clarifiers

During the biological treatment of wastewater the waste is biodegraded by micro-organisms. This is one of the principal goals. A probably even more crucial unit process is the clarification. Indeed, clarifying the “purified” water is necessary to remove the particulate fraction in which the micro-organisms reside. According to Wanner (1994) the washout of sludge contributes to 50 to 80% of the ...
