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...

BACKGROUND Tracheostomy site infection can cause numerous problems. Absorbent foam dressing may be able to prevent proliferation of infectious microorganisms by absorbing the tracheostomy stoma exudate. This study aimed to compare the efficacy of absorbent foam with gauze dressing for prevention of tracheostomy site infection. MATERIALS AND METHODS In this double-blind randomized clinical tri...

to investigate the effects of drought stress and different combinations of animal manure with super absorbent polymer on yield and yield components of corn, a split plots design was conducted based on a randomized complete block design with 3 replications in fars agricultural research center in 2007. irrigation treatments were assigned as the main factor in three levels: 70, 105 and 140 mm evap...

Background & Aims of the Study:  Soil and water pollution to heavy metals is a serious threat for environment and human health. Finding an effective way for refining water from these metals is very important. The aim of this study was modifying electrospun polymeric nano fibers and studying its efficiency for copper ion omission in water solutions. Materials & Method...

Acoustic radiation through a system of double-walled shells, lined with porous foams, and stiffened by annular plates simultaneously is studied. Based on modeling, the foams as absorbent fluid property, acoustic characteristics structure are presented for various sandwich construction means vibro-acoustic finite element method automatic matching layer technology. It noted that equipping enhance...

The authors present a case of unusual rise in inspired carbon dioxide due to misplaced absorbent canister.

In a second experiment, a microstrip patch antenna was attached directly to a thermalite block (440 x 215 x 100 mm) and the dipole-like radiation panems measured in an anechoic chamber. The results given in Figs. 20 and h show the effect of placing radar absorbent material (RAM) on the block ends to absorb the surface wave contribution. With no absorbent material the surface waves result in som...

The lithium bromide chillers supplied from solar collectors are used to provide proper environmental conditions into industrial and civil buildings. To maintain the appropriate values for the temperature into the chiller's boiler, a control unit is introduced to avoid crystallization of the absorbent. The liquid flow process of the absorbent within the pipes of the chiller is a non-linear proce...
