Water-insoluble polyelectrolyte complexes of cellulose acetate sulphate in the form sodium salt (Na-CAS) and aminoglycoside antibiotic (AB) kanamycin (KAN) were obtained by mixing components aqueous solutions. The composition was determined accordance with medium pH order. increase Na?CAS cellobiose units per mole AB has been shown to correlate decrease value. complex formation studied Fourier ...

In order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(Triticum aestivum L.), an experiment was carried out at the Experimental Farm of Shiraz University. Results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

The immune bodies of antipneumococcus serum are completely precipitated by 38 to 42 per cent. saturation with ammonium sulphate. They are incompletely precipitated by (a) ammonium sulphate in less than 38 per cent. saturation, (b) saturation with sodium chloride, (c) dilution and saturation with carbon dioxide, (d) removal of crystalloids by dialysis. The immune bodies of antipneumococcus serum...

The flowability of spray-dried laundry detergent is important for manufacturing process performance and reliability, product quality; it strongly dependent on formulation. In this work, a detailed study four model formulations provides fundamental understanding the role particle composition, micro-structure, powder flow behaviour. All powders studied contained sodium salt linear alkylbenzene su...

The durability of consolidated highly porous limestones was tested after salt and freeze–thaw cycles. Three limestone lithotypes that were commonly used in construction the Central-European region during previous centuries selected for tests. Specimens Miocene with four different types ethyl silica-based consolidants (KSE 100, KSE 300, 300 E, HV). After consolidation, samples exposed to freeze ...

We investigated the role of insulin in salt-sensitive hypertension in Dahl salt-sensitive and salt-resistant rats. The rats were kept in metabolic cages, and sodium intake and urinary sodium excretion were measured. In salt-sensitive rats receiving a 0.3% NaCl diet, sodium retention was significantly greater at weeks 1 and 2 in rats that received an insulin infusion than in those receiving a sa...

The relationship between the binding of sodium n-dodecyl sulphate and protons to histone H1 has been investigated by equilibrium dialysis and titrimetry. The data cover the pH range 3.2-10 and surfactant concentrations up to 3.0×10-3 mol dm-3. A theoretical approach based on the binding potential concept of Wyman is presented and has been used to make estima...

The present study was concerned with the selection of suitable surfactant for the production of alpha amylase by Bacillus subtilis GCBM-25 in 250 ml shake flask containing 50 ml of fermentation medium. Different surfactants (laundry soap, detergent powder, sulphonic acid, acyle benzene sulphonic acid, liquid soap, Tween 80, sodium silicate, bath soap, sodium tripolyphosphate, sodium lauryl ethe...
