در این پژوهش از روش آماری سطح پاسخ جهت بهینه سازی شرایط فرآیند هیدرولیز پروتئین روده و معده ی گوسفند با استفاده از آنزیم آلکالاز (2.4l)، استفاده شد. فاکتورهای مورد بررسی در این تحقیق دما، زمان و نسبت آنزیم به سوبسترا بودند که برای رسیدن به بیشترین میزان درجه هیدرولیز و بازیافت نیتروژن این متغییرها در محدوده ی دمای 52-43 درجه سانتیگراد، زمان 190-65 دقیقه و مقدار آنزیم 95-50 (anson unit/kg protei...
AIM To investigate the influence of socioeconomic factors, mental health service availability, and prevalence of mental disorders on regional differences in the suicide rate in Slovenia. METHODS The effects of different socioeconomic factors, mental health service availability, and mental disorders factors on suicide rates from 2000-2009 were analyzed using a general linear mixed model (GLMM)...
this study examined the effect of urbanization on agricultural production in abia state. specifically, it categorized the land tenancy status of the farmers, analyzed the effect of urbanization on agricultural productivity and identified the constraints to agricultural productivity. multistage random sampling technique was used to select the respondents. primary data collected using structured ...
Flight and Maintenance Planning (FMP) addresses the question of which available aircraft should fly and for how long, and which grounded aircraft should perform maintenance operations, in a group of aircraft that comprise a unit. The objective is to achieve maximum availability of the unit over the planning horizon. The availability of a unit is expressed in terms of the total number of aircraf...
This paper investigates the availability characteristics and the reliability of a three-dissimilar-unit repairable system with two diierent repair facilities. Under some practical assumptions, we obtain the explicit expressions of the state probabilities of the system, and then the explicit expressions of the following performance measures of the system: (1) the pointwise and steady-state avail...
background: in the recent years nanostructured materials have been the focus of researches due to their wide-spread possibilities to provide new shapes and structures for some materials. microemulsions can provide uniform nano-sized droplets for templating. microemulsions are isotropic, thermodynamically-stable systems of oil, water and surfactant with a 20-200 nm droplet size. they can be prep...
BACKGROUND Intensive care unit (ICU) beds, a scarce resource, may require prioritization of admissions when demand exceeds supply. We evaluated the effect of ICU bed availability on processes and outcomes of care for hospitalized patients with sudden clinical deterioration. METHODS We identified consecutive hospitalized adults in Calgary, Alberta, Canada, with sudden clinical deterioration tr...
Reuse of teaching resources is recognized to be essential for cost-effective development and maintenance of on-line teaching environments. We offer a novel approach to the reuse and sharing of on-line teaching unit designs, based on serving unit templates in a distributed environment. The approach suggested will increase the level of reuse, simplify and speed up material creation by non-technic...
