Plastic materials are commonly used for storing food stuffs and medicines. Chemical substances used in the manufacture of plastic goods are found to migrate in the food stuffs used. The migration of UV absorbents and oxidisable matter was found to be more when used for longer periods.

Entomopathogenic fungi are promising pest-control agents but their industrial applicability is limited by their thermosusceptibility. With an aim to increase the thermotolerance of Isaria fumosorosea SFP-198, moisture absorbents were added to dried conidial powder, and the relationship between its water potential and thermotolerance was investigated. Mycotized rice grains were dried at 10℃, 20℃...

abstract water deficit and consecutive droughts have lead to drought stress in most parts of the world recently. we need prepare a good program to use better available water. different material can be used to increase water use efficiency. super absorbent is one of the materials used around the world. these materials absorb water in the soil so that reserved water is usable by plant in the time...

Carbon capture technologies have been recognized as a potential alternative to alleviate global warming. and storage (CCS) is preferred over carbon conversion utilization (CCU) due its lower operating costs higher CO2 reduction capability. Nevertheless, has the be more economical if value-added products are produced. This highlights importance of assessing routes alternatives in management. rev...

According to questionnaire studies, speech is the most annoying sound source in open-plan offices [1]. The most distracting speech comes from the nearest workstations. Therefore, speech privacy between workstations should be as high as possible, that is, the speech transmission index, STI, should be low. This presupposes that the speech is properly attenuated, e.g. using absorbents, screens, an...

Abstract A thermodynamic model is developed for a forward osmosis (FO) absorption heat pump capable of purifying graywater and providing year-round space conditioning with low-temperature as the primary energy input. The applied to 16 potential absorbents, six are selected parametric studies on desorber temperature, absorber condenser sink temperature determine effects ratio (defined total usef...
