1.531211SMJ8 Jeewanu, the autopoeitic eukaryote, was prepared under oxygenic conditions and the effect of addition of different concentrations of formaldehyde in the PEM on the degree of Mo the proton release during exposure to sunlight was investigated. It was observed that on exposure to sunlight, the colourless form Mo 6+ is changed to blue coloured Mo minutes of exposure. The intensity o ph...
Methods: In this quasi experimental and interventional study a sample of 20 MS patients (mean age: 36.75 years) with Expanded Disability Status Scale scores (EDSS) 1.0 to 4.0 were randomly assigned to a ‘pharmacologic treatment’ (Ph) group and a combination group of ‘pharmacologic treatment& treadmill training’ (PhTT). All these individuals used the drugs of choice ‘Rebif’ and ‘Avonex’. The int...
to estimate the prevalence of subacute ruminal acidosis (sara) in dairy cows, a total of 196 ruminalfluid samples were drawn by rumenocentesis from 10 dairy herds of khorasan razavi province, northeast ofiran. two groups of 12 cows, early lactation and mid-lactation cows were sampled in each dairy herd andruminal ph was determined immediately using a portable ph-meter. a total of 54 cows (27.6%...
In suspensions of colloidal particles different types of interactions are in a subtle interplay. In this report we are interested in sub-micro meter sized Al2O3 particles which are suspended in water. Their interactions can be adjusted by tuning the pH-value and the salt concentration. In this manner different microscopic structures can be obtained. Industrial processes for the production of ce...
in islamic civilization, rhetoric is the product of a great attempt to find out the secrets of quranic language; nevertheless, the achievements of such studies have been mechanically applied to persian which, compared to arabic, has a different linguistic system and literary conventions. this approach has brought about problems in defining literary terms, internal rhythm being one of them. this...

با توجه به جمعیت کثیر شتر در ایران، به خصوص در منطقه سیستان و بلوچستان و همچنین خشک سالی های اخیر در این منطقه و کمبود علوفه مناسب برای پرورش سایر دام ها، شتر به عنوان یک حیوان مناسب با شرایط اقلیمی این منطقه است. همچنین شیر شتر حاوی همه مواد مغذی در شیر گاو است. در این مطالعه به بررسی ماندگاری و خواص فیزیکوشیمیایی شیر خام شتران منطقه سیستان طی نگه داری در 4 درجه سانتی گراد پرداخته شد. نمونه...

 Aquaponics is a cultivation method that combines aquaculture and hydroponics which can produce two products, namely plants fish at time on relatively narrow land. The important thing in implementing aquaponics to maintain water quality so it remains the standard of products. Automatic control make easier for cultivators more efficiently. Therefore we need an aquaponic system focuses para...
