Air conditioning plays a significant role to maintain cool atmosphere in warm conditions, However, the power consumed by machine is higher. The commercial prevailing cooling systems are required operate ventilation and buildings turn consumes more power. These apart from consuming electricity it also adds CO 2 emissions our environment. energy consumption can be decreased assistance of effectiv...

This paper presents a comprehensive refinement of system modeling and optimization study of air-cooled direct expansion (DX) refrigeration systems for commercial buildings to address the energy saving problem. An actual DX rooftop package of a commercial building in the hot and dry climate condition is used for experimentation and data collection. Both inputs and outputs are known and measured ...

Tulip is one of the most important bulbous genera in world’s floriculture. It known that cold exposure bulbs before planting required to break bulb dormancy and promote plant’s flowering. Preparation procedures performed by breeders differ duration thermal level, choice procedure depends on genotype’s sensitivity temperature; however, little about metabolic responses underlying different behavi...

Recent research on seeds of bio-diesel plants like Jatropha curcas, constituting 40-50% bio-crude oil indicates its potential as one of the most promising alternatives to conventional sources of energy. Also, limited studies on utilization of de-oiled cake have revealed that Jatropha bio-waste has good potential to be used as organic fertilizers produced via aerobic and anaerobic treatment. How...

The aim of this paper was to test the use of dual microbial inoculation with mycorrhizal and saprotrophic fungi in onion cultivation to enhance yield while maintaining or improving the nutritional quality of onion bulbs. Treatments were two-factorial: (1) arbuscular mycorrhizal fungi (AMF): the mix corresponding to fungal part of commercial product Symbivit (Glomus etunicatum, G. microaggregatu...

experiments were conducted at the horticulture research farm of horticulture department, bangabandhu sheikh mujibur rahman agricultural university (bsmrau), salna, gazipur during december, 2007 to may, 2009 to investigate the effect of bulb cutting and potting media on propagation of hippeastrum. the bulb cutting significantly influenced all the parameters except days required to first leaf eme...
