The present study is focussed on chromium removal by indigenous chromium-resistant microorganisms isolated from soil and sludge samples of an industrial site. optimal bioremediation conditions, namely temperature, hexavalent (Cr(VI)) initial concentration, pH time were determined using a full factorial design at two levels. results showed that the 54 bacterial strains, S10C1 identified as Bacil...

vegetation studies measuring the accuracy of the results is important. the purpose of this study is to compare shape and distribution plots on different levels for species richness measurements.thiscomparison was in three design whittaker, stohlgern and a new design (ariz) in ariz, sanandaj.designed proposition (ariz) obtainedon base changes in the size and distribution plotin design stohlgern ...

physiological effect of six levels of water stress (0, -0.1, -.03, -0.6, -0.9 and -1.2 mp) was studied on seed germination and plumule as well as radicule growth length in three species namely: agropyron elongatum, agropyron desertourm and secale montanum. polyethylene glycol (peg) was used to provide appropriate water potentials. a total of 100 seeds in four replications (petri dishes) were so...

This paper focuses on Optimal Experimental Design to train a Projection Pursuit Regression (PPR) model used for fault detection. A novel experimental design method, referred to as Gaussian Probability Design, is proposed and compared with the conventional Factorial Design. The Gaussian Probability Design automatically searches for the sparseness of the data, and adds pairs of training data on b...

Due to the fact that it breaks down into acrylamide over time, polyacrylamide is one of most important sources in soil. As a strategy for bioremediation, breakdown by action microbes has seen gradual but consistent increase attention all world. A previously isolated molybdenum-reducing bacterium with amide-degrading capability was further identified on significant parameters contributing optimi...

in order to investigation of morphological traits, yield and its components in three cultivars of grain sorghum (kimia, sepideh, payam) and two promising lines (m5, m2) under four density (240000, 205000, 170000 and 135000 plant/m2), experiment was conducted as factorial design based on randomized complete block design with three replications in birjand agricultural research station, during 200...
