The water-insoluble fraction, obtained after successive treatment of an insoluble fraction of a buffer-homogenate of Zea mays L. hybrid B73 x Mo 17 shoots with 3 molar LiCl and hot water, was treated with alpha-amylase to remove starch. This fraction has been subjected to sugar composition analysis and the major glycosidic linkages were determined. The results suggest that the water-insoluble f...

A model is presented of a polymer electrolyte fuel cell including slow transient effects of liquid water accumulation and evaporation in gas diffusion electrodes GDEs and gas channels. The model is reduced dimensionally, coupling a one-dimensional 1D model of gas and coolant channel flow to 1D models of transport through the membrane electrode assembly MEA and bipolar plates. An asymptotic redu...

The present study was designed to evaluate the short-term effects of intravenous administration of furosemide on key functions in the kidney cortex and the outer and inner medulla of rats by using magnetic resonance imaging (MRI). Renal tissue water content, renal tissue oxygenation (in relation to the magnetic resonance spin-spin relaxation rate), the apparent diffusion coefficient (ADC) of wa...

background: the dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...

Fresh water is a vital natural resource. Earth observation time-series are well suited to monitor corresponding surface dynamics. The DLR-DFD Global WaterPack (GWP) provides daily information on globally distributed inland based MODIS (Moderate Resolution Imaging Spectroradiometer) images at 250 m spatial resolution. Operating this spatiotemporal level comes with the drawback of moderate resolu...

population growth as well as global fresh water shortage problem have necessitated the use of unconventional water resources in agricultural sector, as the largest consumer of fresh water, especially in arid and semi-arid regions. in this study, the effect of four irrigation methods on yield, uptake of water and important nutrients, and the salt accumulation in soil was investigated using a com...

OBJECTIVE In the present work, the effects of different fractions of Coriandrum sativum (C. sativum), on pentylenetetrazole (PTZ)-induced seizures and brain tissues oxidative damage were investigated in rats. MATERIALS AND METHODS The rats were divided into the following groups: (1) vehicle, (2) PTZ (90 mg/kg), (3) water fraction (WF) of C. sativum (25 and 100 mg/kg), (4) n-butanol fraction (...

Interactions of ionic liquids (ILs) with water are of great interest for many potential IL applications. 1-Ethyl-3-methylimidazolium (emim) acetate, in particular, has shown interesting interactions with water including hydrogen bonding and even chemical exchange. Previous studies have shown the unusual behavior of emim acetate when in the presence of 0.43 mole fraction of water, and a combinat...

Although the production of proteolytic enzymes by different strains of Aspergillus oryzae has been investigated in submerged culture (5, 15), in static liquid culture (3, 11), and on solid substratum (8-10), there appear to be few reports pertaining to the comparative evaluation of these different methods on the elaboration of proteinases by specific strains of A. oryzae. K. Mogi (13) compared ...
