Forest harvesting can increase solar radiation in the riparian zone as well as wind speed and exposure to air advected from clearings, typically causing increases in summertime air, soil, and stream temperatures and decreases in relative humidity. Stream temperature increases following forest harvesting are primarily controlled by changes in insolation but also depend on stream hydrology and ch...
Recent impetus has been given to research concerning the relationship between biological systems and the microclimate. However, extensive and detailed microclimatological measurements have been made only for limited situations. It would be of great value if quantitative relationships could be obtained between the highly variable microclimate and the relatively homogeneous macroclimate. There ar...
Species are commonly segregated along gradients of microclimate and vegetation. I explore the question of whether segregation is the result of microhabitat partitioning (biotic effects) or choice of differing microclimates (abiotic effects). I explored this question for four ground-nesting bird species that are segregated along a microclimate and vegetation gradient in Arizona. Birds shifted po...
This study investigates the influence of microclimate factors on uniformity silk thickness and explores application a mechatronic system for optimal control maintenance. As environmental conditions vary daily seasonal basis, managing temperature relative humidity becomes crucial consistent cocoon production. The review delves into significant role in growth development silkworms, highlighting p...
The growth of the leading countries’economies leads to rapid development megacities and changes in urban areas. Currently, more modern high-rise civil buildings are being built, resulting an increasing density areas activity transport infrastructure. This causes major structure development, which a change aeration microclimatic conditions Solar radiation plays active role shaping microclimate s...
We examined the feasibility of providing ambient air during exercise and conditioned (cooled) air during rest on reducing physiological strain and optimizing tolerance time. Six male soldiers attempted 250-min exposures in hot/dry and hot/wet environments. Subjects wore chemical protective clothing over the combat vehicle crewman uniform and an air-cooled vest. They alternated between 50 min of...
BACKGROUND A microclimate monitoring study was conducted in 2008 aimed at assessing the conservation risks affecting the valuable wall paintings decorating Ariadne's House (Pompeii, Italy). It was found that thermohygrometric conditions were very unfavorable for the conservation of frescoes. As a result, it was decided to implement corrective measures, and the transparent polycarbonate sheets c...
The surface pH of rat distal colonic mucosa and human rectal mucosa was measured in vitro using first a small pH electrode with a flattened tip. In buffer with pH 7.56 the mean rat colonic surface pH was 6.72. Lowering the buffer pH in steps resulted in a small fall in surface pH, the values being buffer pH 7.06 surface pH 6.64, buffer pH 6.58 surface pH 6.61 and finally buffer pH 6.09 surface ...
The use of greenhouses with controlled microclimate according to the plants needs is an important way to increase the production of fruits and vegetables and has recently become one of the hottest topics in precision agriculture. In order to know and to control the greenhouse microclimate, smart sensing nodes with wireless communication capabilities are recommended. As one of the promissory pro...
In the last decades, several studies have revealed how critical the urban heat island (UHI) effect can be in cities located in cold climates, such as the Canadian one. Meanwhile, many researchers have looked at the impact of the city design over the urban microclimate, and have raised concerns about the development of too dense cities. Under the effect of the “Places to Growth” plan, the city o...
