short growing season in cold regions is an important factor in not achieving a maximum root yield in sugar beet crop. in an investigation on possible ways to limit the effect of short season culture on the crop, six harvest dates and three sugar beet varieties were considered. the experiment was conducted as a factorial with randomized complete block design in three replications, from 1996-1998...

to study the stability and adaptability of grain yield and genotype ‎‏×‏‎ environment interaction, ‎‎19 promising triticale lines/varieties were evaluated in moghan, mashhad and zabol experimental ‎stations during 2001 to 2003 cropping seasons. the experimental design in all the locations and ‎years was completely randomized block design with three replications. combined analysis of ‎variance c...

the selection of high yielding varieties with good stability‏ ‏is an important objective in rice breeding ‎programs. the grain yield of eight rice lines with a check (nemat) were compared‎‏ ‏on six locations of gilan ‎and mazandaran provinces during two years, using rcbd with four replications. combined analysis of ‎variance showed that the effect of variety and year ‎‏×‏‎ location ‎‏×‏‎ variet...

Abstract UV photolysis and UV based advanced oxidation processes (AOPs) are gaining more and more attention for drinking water treatment. Quantum yield (f) and molar absorption coefficient (ε) are the two critical parameters measuring the effectiveness of photolysis of a compound. The product of the two was proposed as a fundamental measure of a constituent’s amenability to transformation by ph...

Eleven strains of an undescribed species of Clavispora fermented D-xylose directly to ethanol under aerobic conditions. Strain UWO(PS)83-877-1 was grown in a medium containing 2% D-xylose and 0.5% yeast extract, and the following results were obtained: ethanol yield coefficient (ethanol/D-xylose), 0.29 g g (57.4% of theoretical); cell yield coefficient (dry biomass/D-xylose), 0.25 g g; maximum ...

This paper presents an application of a method for multicriteria decision making, namely InterCriteria Analysis (ICrA). The ICrA method gives possibility to compare some criteria or estimated by them objects. There we have applied this method to create а structural identification of а mathematical model of a whey fermentation process. The process is for production of unicellular protein by whey...

response surface models predict crop yield based on crop density and this is an important tool for evaluation competition at different density and hence selection of optimum density based on yield. in order to study intra and inter specific competition in intercropping bean (phaseolus vulgaris) and sesame (sesamum indicum), an experiment was conducted at the agricultural research station, ferdo...

The paper investigates the static and dynamic behavior of a continuous flow bioreactor for the aerobic biodegradation of municipal and industrial waste. The unstructured kinetic model for the bioreactor accounts for oxygen limitation in the bioreactor model while the growth rate is described by the biomass-dependent Contois model. This kinetic model is known to explain the aerobic biodegradatio...

Influence of pulsed electric field (PEF) simultaneous to pressure treatment on moisture expression from fine-cut cellular raw material has been investigated. Dependencies of specific conductivity σ, liquid yield Y , instantaneous flow rate v and qualitative juice characteristics at different modes of PEF treatment are discussed. Three main consolidation phases were observed in a case of mechani...
