The metabolic and temperature response to mild cold were investigated in summer and winter in a moderate oceanic climate. Subjects were 10 women and 10 men, aged 19-36 years and BMI 17-32 kg/m2. Metabolic rate (MR) and body temperatures were measured continuously in a climate chamber with an ambient temperature of 22 degrees C for 1 h and subsequently 3 h of 15 degrees C. The average metabolic ...

The shape of the air flow in the interior is heavily influenced by the air distribution system and the way air enters and exits. By numerically simulating flow by computational fluid dynamics, one can determine the flow pattern and temperature distribution and, with the help of the results, provide an optimal design of the air conditioning system. In this study, a chamber was first constructed ...

With the principle of the time expansion chamber and the additional measurement of the position of the avalanche along the circumference of the anode wire it is possible to reconstruct the spatial distribution of the primary ionization in space. A position resolution for minimum ionizing tracks of a 5 30 urn is expected. First tests and concepts for vertex detectors are presented.

Research exploring greenhouse environment control over the last 50 years has led to significant advancements in understanding effects of environmental factors on plant growth and productivity. This article provides a comprehensive review research conducted years, including methodology, results, implications for future agriculture.
