arctic tundra and hot deserts (Pace‚ 1997). The hairy cap moss species‚ or Polytrichum commune‚ is one of the more than 15‚000 species of moss present in nature. Hairy cap moss is a medium sized moss that is prevalent in areas that have high levels of humidity. The purpose of this research project was to investigate the differences in microbial diversity between lichen on bare rocks and hairy cap mosses in the annual community. Based on background information‚ a hypothesis was formed that lichen on bare

DIFFERENT STORAGE TECHNIQUES FOR FRUITS AND VEGETABLE Food spoilage: Every change in food that causes it to lose its desired quality and eventually become inedible is called food spoilage or rotting. Factors affecting storage life The natural limits to the post-harvest life of all types of fresh produce are severely affected by other biological and environmental conditions: Temperature: An increase in temperature causes an increase in the rate of natural breakdown of all produce as food reserves

Rural Khmer house Despite indoor and outdoor temperatures of 36°C and up to 80% relative humidity the old rural Khmer houses are very comfortable‚ both at ground level and on the upper floor. In spite of the absence of electric or mechanical air conditioning‚ a draught-free environment appears to be attained simply by means of natural ventilation. Typically‚ rural Khmer houses are rectangular two-storey buildings‚ varying in size from four by six metres to about six by ten metres. The basic

Homeostasis is a mechanism that allows organisms to maintain stable internal conditions (Reece 2014). The capability to perform homeostasis is essential for the survival of all organisms. Homeostatic mechanisms include a range of responses that regulate internal imbalances‚ including body temperature. A vital component of homeostasis is known as thermoregulation‚ the process of maintaining temperatures within a normal range (Reece 2014). When ambient temperatures change‚ animals must control their

3.1 Metabolic Load: The metabolic activities inside human body constantly create heat and humidity (i.e. perspiration). This heat passes through the body tissues and is finally released to the cabin air. This amount is considered as a heat gain by the cabin air and is called the metabolic load. The metabolic load can be calculated by Qmet = Σ MADU Passengers Where M is the passenger’s metabolic heat production rate. (It is assumed from ISO 8996 based on various criteria for driver: M = 85 W/m2

It is of utmost importance that the atmosphere in which the roots grow is maintained at 100% relative humidity to prevent dehydration. A drawback to current aeroponic systems is maintaining root health in the event of pump malfunction or loss of power. Without the spray of nutrient enriched water‚ root systems will not remain healthy for long. They
