Forty eight 8-month-old male goats were divided into three groups. In each group, eight goats were feedrestricted for 45, 60 or 75 days, and eight goats served as the control. Restricted groups were fed with a maintenance ration, and the control goats were fed with a ration supporting 50 g of daily weight gain. At the end of restriction period, the restricted goats were offered the same ration ...
Batch and continuous systems are of multivariable in nature. A multivariable system is one in which one input not only affects its own outputs but also one or more other outputs in the plant. Multivariable processes are difficult to control due to the presence of the interactions. Increase in complexity and interactions between inputs and outputs yield degraded process behavior. Such processes ...
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
100 patients with beta-thalassemia trait, comprised of 55 men and 45 women, participated in a study to measure serum lipoproteins. the results were compared with the data obtained from 100 control subjects of the same age and sex. a significantly lower level of mean serum total cholesterol and ldl cholesterol, and a much higher level of hdl cholesterol were obtained in beta-thalassemia trait as...
Background: It seems that green tea and exercise training may have benefits for improving body composition and blood lipids. However, there are limited documents in the menopause population. Therefore, the aim of this study was to evaluate effects of green tea consumption and aerobic- resistance training on lipid profile and body composition in overweight and obese postmenopausal women. Materia...
The determination of time-varying profiles through dynamic optimization is an exclusive characteristic of optimal control problems; however, these types of problems become more challenging when variability and uncertainty in any parameter is included. In biodiesel production, there are inherent uncertainties arising due to variation in initial composition, operating parameters, and mechanical e...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
The purpose of this study was to survey the impact of collaborative learning on development of students’ composition and writing skills and its comparison with classic method. Statistical population was students in 7th grade in Saveh in 2011-2012 academic year from whom 140 students (70 males and 70 females) were selected as the sample by cluster sampling. The required data were provided throug...
this study was evaluated to study the effects of vitamin c and the bacteria bacillus subtilis, b.lichniformis on growth and carcass composition of litopenaus vannamei. three treatments were applied, treatment fed with probiotics (4×1010 cfu/kg food), treatment with vitamin c (140 mg/kg food) and the control group. three replicates were used for each treatment. shrimps were kept in nine 300-lite...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
