As reverse osmosis (RO) desalination capacity increases worldwide, the need to reduce its specific energy consumption becomes more urgent. In addition to the incremental changes attainable with improved components such as membranes and pumps, more significant reduction of energy consumption can be achieved through time-varying RO processes including semi-batch processes such as closed-circuit r...

یکی از دلایل اصلی بروز خطا در ساخت بند موصولی سوی زبان آموزان فارسی که مشغول یادگیری آلمانی هستند، استفاده ضمیر برای عنوان می شود با هسته به لحاظ جنس دستوری و شمار مطابقه دارد. مقابل، تنها حرف ربط «که» بهره برد ارتباط نحوی یا معنایی ندارد. دیگر، راهبردهایی هر دو مورد قرار گیرند نیز کاملا متفاوت اند. بر اساس فرضیه پژوهش حاضر، نظر رسد بیشترین خطاها بخش رخ دهند: یک سو، انتخاب نادرست روبرو هستیم. ع...

until now, there have been various studies concerning bottle-fed and breast-fed children. prevalence of allergic manifestations like eczema and asthma among bottle-fed children is much higher than healthy controls. in this study, we found that respiratory infection for breast-fed children was 3.1%, whereas in bottle-fed children it was 25.1%for gut disorders, 9.2% in breast-fed vs.13.1 % for bo...

Before making a comparison of grass-fed vs. grainfed beef it is necessary to first define these two beef types. An animal is considered grass-fed, according to the USDA Grass Fed Marketing Claim Standards, when grass and forage are the “feed source consumed for the lifetime of the ruminant animal, with the exception of milk consumed prior to weaning. Animals cannot be fed grain or grain by-prod...

introduction: this study aimed to assess the incidence of breastfeeding-associated hypernatremia and related risk factors among hospitalized hyperbilirubinemic neonates. methods: this prospective study was conducted at nemazee hospital affiliated to shiraz university of medical sciences during one year to determine the association between hypernatremia (serum sodium concentration of >150 meq/l)...

Optimal productivity of S. cerevisiae cultures can be achieved through the regulation of the ethanol concentration at a low value. In this study, a robust control strategy is developed, which requires very little knowledge about the process, i.e. only one yield coefficient and the on-line measurement of the ethanol concentration. A Youla parametrization is selected in order to reject asymptotic...

A process comprising two-step fed-batch cultivation has been investigated for the production of ectoines using the halophilic bacterium Halomonas boliviensis DSM 15516(T). The first cultivation was performed under optimal conditions for cell growth and resulted in cell mass concentration of about 41 g l(-1) after 24 h of cultivation. During the second cultivation at higher salt concentration, a...

The present study was designed for the production and optimization of the C12-C14 sophorolipid, using the yeast Candida bombicola ATCC-22214. The fermentation was carried under fed-batch culture conditions i.e., maintaining 15% coconut oil and 10% glucose as hydrophobic and hydrophilic carbon sources, respectively. A maximum yield 54.0 g/L (in 234 h) was achieved. A significant antimicrobial ac...
