the effect of levels of nitrogen on growth and nitrogen uptake patterns and grain protein quality of grain sorghum was investigated by two experiments which were conducted at pakdasht-tehran in 2003. in a completely randomized design with three replications, grain sorghum (sorghum bicolor (l.) moench) hybrid h-726 was grown under greenhouse conditions using water culture technique. the first ex...

The blood preservative introduced by Loutit and Mollison (1) consisting essentially of a sodium citrate-dextrose mixture of relatively low pH, has proved superior to previously employed preserving fluids. The original formula and many subsequent modifications have a rather high volume. This produces considerable dilution of the plasma proteins. The purpose of this study, begun in June 1944, was...

Solution culture experiments were carried out to study the kinetics at cotyledon stage (11-day-old) and the effect of different NO3/NH4 on NO3 and NH4 uptake at seedling stage (31-day-old) with two cultivars of sugar beet, including Tianyan7 and Tianyan8. NO3 uptake by sugar beet seedlings at cotyledon stage (11-day-old) reached equilibration after 2 hours of adaptation, and NH4 uptake reached ...

In situ gelling systems based on temperature-dependent phase transition containing pheniramine and phenylephrine were developed using combination of Poloxamers, different cellulose polymers (HPMC) and xanthan gum. The formulations were tested for in vitro gelation, appearance, pH, drug content, in vitro drug release, mucoadhesive strength, preservative effi cacy and stability. In vitro release ...

Effects of 1% or 0.5% chitosan (CHI), 10% or 5% aqueous extract of ginger, onion and garlic (GOG) and their composite solutions (1% CHI+10% GOG, 0.5% CHI+5% GOG) on quality and shelf life of stewed-pork were evaluated. Microbiological (total bacterial count), chemical (pH, total volatile basic nitrogen (TVB-N), peroxide value (POV), 2-thiobarbituric acid (TBA)) and sensory characteristics were ...

Microbial growth did not occur when cucumbers were preserved without a thermal process by storage in solutions containing acetic acid, sodium benzoate, and calcium chloride to maintain tissue firmness. The concentrations of acetic acid and sodium benzoate required to ensure preservation were low enough so that stored cucumbers could be converted to the finished product without the need to wash ...

DESCRIPTION Tuberculin Purified Protein Derivative (Mantoux) TUBERSOL for intradermal (Mantoux) tuberculin testing is available in a stabilized solution bio-equivalent to 5 U.S. units (TU) PPD-S per test dose (0.1 mL). TUBERSOL is prepared by Aventis Pasteur Limited from a large Master Batch, Connaught Tuberculin (CT68) and is a cell-free purified protein fraction obtained from a human strain o...

5 genetically distinct subtypes of muscarinic acetylcholine receptors have been cloned from human and rat tissues [l, 2 , 31 and these have been dubbed ml, m2, m3, m4 and m5. Each individual subtype has been expressed in animal cells and their pharmacology determined (4). It appears that the pharmacological subtypes Ml, M2 and M3 correspond to the cloned subtypes ml, m2 and m3. However, m4 and ...

alstroemeria flower is one of the most important cut flowers in the world. some materials can increase longevity of cut flowers. the aim of this research was evaluating the effect of some chemical solutions on postharvest alstroemeria (cv. stratus) cut flowers. this experiment was conducted with two factors of sucrose at four concentrations, 0, 5, 10 and 15 g/l and salicylic acid (sa) at four c...

In this research we experimented with a new and rapid way of analyzing wood. Near Infrared (NIR) spectroscopy together with multivariate analysis is becoming a widely used technique in the field of forest products especially for property determination and is already firmly established in the pulp and paper industry. This method is ideal for the chemical analysis of wood, and therefore preservat...
