Measurements of DSC, NMR and high-frequency spectroscopy have been done on PEO-H2O and PEO-H2O-HQ mixed systems. DSC measurements show that water molecules contained in PEO are divided roughly into two species: freezable water and non-freezable water. By 1H-NMR measurements, PEO and H2O protons show an absorption peak around 3.6 ppm and 4.5 ppm, respectively. All the PEO-H2O samples containing ...

The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘S...

an investigation on the thermal performance of the soil as geothermal heat energy storage medium has been conducted. the thermal characteristics of the soil storage and the heat transfer from a heat exchanger in the soil, surrounding and bottom surface will be discussed. this investigation forms a contribution to a project to realize such storage to be charged from a solar heating system. this ...

for investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the research field of islamic azad university, jiroft, iran in 2013-2014. the main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of crop ...

Jejunostomy losses of Na+ and water during enteral nutrition after massive intestinal resection may be severe. We have attempted to analyse this practical problem by using an in vivo perfusion technique in healthy volunteers to study Na+, water and nutrient absorption from a short (25 cm) segment of jejunum during perfusion of an isotonic solution of the elemental diet Vivonex. Further solution...

This paper presents the results of a Forest Products Laboratory study regarding the effects of resin content, particle size, and molding pressure upon specific gravity, strength, and water absorption of hardboard products made of wood waste treated with powdered phenolic resin. Modulus of rupture in bending was found to vary approximately as the cube of specific gravity, whereas water absorptio...

In order to clearly understand the intrinsic microwave absorption properties of carbon nanomaterials, we proposed an efficient strategy to synthesize high purity metal-free carbon nanotubes (CNTs) over water-soluble K2CO3 particles through chemical vapor decomposition and water-washing process. The comparison results indicated the leftover catalyst caused negative effects in intrinsic microwave...

dry beans are rich sources of dietary fiber and phytochemicals such as flavonoids and phenolics that exhibit good functional properties. in current study line, cooking and soaking time effects were investigated on water absorption, splitting and texture properties of different iranian red kidney beans to determine the best lines and the best soaking time for industrial use. d81083 line showed t...
