Gels of low molecular weight gelators (LMWGs) are self-assembled, thermoreversible, viscoelastic materials which can also be rendered sensitive to light, pH or chemical substances by simple chemical modifications. In addition, the ability of some of these LMWGs to gelate water (hydrogelators) makes these gels interesting, new materials for drug delivery applications. In this paper, for the firs...

The traditional coffee with the greatest taste is called arabica. One of ingredients made from beans and used for air freshener oil. Soxhlet extraction method, a separation technique that often to separate one or more compounds solid liquid by adding solvent, processes making This research has been done before, but comparison different types solvents inclusion differences in time not done. purp...

bezhi (or beji) is a special sweet and fried cookie which is produced traditionally in west region of iran. in this study, the effect of different temperature levels (150, 165 and 180°c) and frying time (1 to 8 min) on physicochemical properties of bezhi was investigated. the obtained results showed that increasing frying time up to the first 3 minutes causes a significant increase in sample vo...

We examine factors controlling the photochemical oxidation of SO2 in tropospheric aerosols using a gas-aqueous photochemical model. Over a range of liquid water contents (3x10 -4g H20 m -3 to 9 g H20 m -3) and pH values (0 to 8), we find that H202(aq) and O3(aq) provide the major sinks for SO2 in the aqueous phase when pH is held constant at below 5 and larger than 6, respectively. OH(aq) may b...

Cytochrome c (Cytc) in airfree, aqueous media (pH ~7.4; 37°C) can emit e(-)(aq) when exited in single state by monochromatic UV light (λ=254 nm). The obtained Qi(e(-)(aq)) at lower Cytc concentrations is higher compared to the amount obtained at higher substrate concentrations because at >10(-8) mol l(-1) Cytc 'associates' (unstable complexes) are formed, which consume a part of the ejected e(-...

The purpose of the present paper is to present some simplifying modifications of Pfltiger’s method (1) for the estimation of glycogen, that render it available for small amounts of tissue. The suggested modifications involve (a) shortening of the time necessary to hydrolyze the tissue with strong alkali, (b) facilitation of the separation of the glycogen by precipitating it in the presence of c...

OBJECTIVE To determine factors associated with good responses to speech therapy combined with transcranial direct current stimulation (tDCS) in aphasic patients after stroke. METHOD The language function was evaluated using Korean version of Western aphasia battery (K-WAB) before and after speech therapy with tDCS in 37 stroke patients. Patients received speech therapy for 30 minutes over 2 t...

Physicochemical properties of surimi and kamaboko obtained of solubility in acid, alkaline and conventional methods were compared. The results indicated that the highest protein recovery was related to solubility in acid, alkaline and conventional methods, respectively. The highest removal of lipid and myoglobin was observed by solubility in alkali. Excretion of total pigment and sulfhydryl gro...
