To date, most genetic progress for quantitative traits in livestock has been made by selection on phenotype or on estimates of breeding values (EBV) derived from phenotype, without knowledge of the number of genes that affect the trait or the effects of each gene. In this quantitative genetic approach to genetic improvement, the genetic architecture of traits of interest has essentially been tr...
background and objectives: patient satisfaction is a key feature of quality improvement in modern health care systems. the focus of patient satisfaction studies has been on inpatient satisfaction measurement. as such, valid and reliable instruments for assessment of outpatient satisfaction are lacking in the field. this study aimed to develop and validate a brief scale to facilitate assessing o...
در این تحقیق غلظت محلول سیلیکات سدیم در بهسازی سیلت غیر خمیری با روش تزریق الکتروکینتیک بررسی شده است. محلولهای سیلیکات از طریق یک مخزن درکنار الکترود آند به درون خاک تزریق شده اند. تزریق سیلیکات سدیم مقاومت خاک را بسته به غلظت محلول، در مجاورت الکترود آند بین 5 تا 8 برابر افزایش داده است. تزریق 5 و10 درصد از این محلول مقاومت خاک را در کل طول نمونه به مقدار قابل توجه افزایش می دهد. اگرچه محلول ...

introduction : it is clear that if the discharge process takes less time and the patient leaves the hospital bed earlier, the length of hospitalization, and consequently, the waiting time for admission decreases. therefore, the method of use of treatment facilities is somewhat improved. the hospital discharge process, from when the discharge authorization is issued until the patient leaves the ...
a bearingless induction machine has combined characteristics of induction motor and magnetic bearings. therefore, the advantages are small size and low-cost. in the magnetic suspension of the bearingless motors, suspension forces are generated based on the feedback signals of displacement sensors detecting the movement of the rotor shaft. the suspension forces are generated taking an advantage ...
