introduction the demand for food and agricultural products are increasing in a line of population increasing in the world (alexandratos, 2003). it is possible to increase the quality and quantity of agricultural products via extending the farms and producing more products (astaaraei and koocheki, 1995). environmental problems caused by synthetic fertilizers and the high levels of producing and ...

in order to study the effects of integrated application of bio- and chemical fertilizers and application method of biofertilizer on the yield and yield components of maize (zea mays l.), an experiment was conducted in 2008 in shushtar in a factorial arrangement with completely randomized block design with three replicates. treatments were integrated application of biological and chemical fertil...

the aim of the present study was to assess the bio-trickling filter startup for the treatment ofwastewater produced by pegah dairy company at psychrophilic condition. the startup time of a bio-tricklingfilter is directly proportional to the concentration of microbial population. abio-trickling column with a height of150 cm was packed with lava rocks with the liquid recirculated through the pack...

The durability of reinforced concrete strongly depends on the environment in which it is located; any case, and reinforcing bars contains are constantly subject to slow deterioration processes. protection structures is, therefore, essential increase their service life, reducing costs for repair maintenance. commercial widely used coatings mainly based petroleum derivatives (i.e., resins, solven...

Peptide mapping, a key analysis used in the characterization of bio-therapeutic proteins, results in complex chromatograms that are generally difficult to study. The enzymatic treatments applied to the proteins are reproducible, but minor changes in protein structure can result in very slight changes in the quantities of protein fragments. Thus, overlaying the chromatograms in a side-by-side or...

Health technology The use of routine antenatal anti-D prophylaxis in the prevention of haemolytic disease in the newborn was examined. Two different target populations were considered, all pregnant women who were rhesus (RhD)-negative and women who were RhD-negative primigravidae only. The two different prophylactic treatments considered were Bio Products Laboratory (BPL) anti-D immunoglobulin(...

In a 42-d experiment, 576 one-day-old Vencobb 308 broiler chicks were used to investigate the effects of lecithin extract (0.5 g/kg), choline chloride 60% (1 g/kg) and Bio choline (1 g/kg) in diets of moderate and high energy in a 4 × 2 factorial arrangement on performance and certain physiological traits in broiler chickens. The inclusion of Bio choline and lecithin extract in the diet signifi...
