We consider solutions uf to the one-dimensional Robin problem with heat source f∈L1[−π,π] and parameter α>0. For given m, M, s, 0≤m<s<M, we identify sources f0, such that uf0 maximizes temperature gap max[−π,π]⁡uf−min[−π,π]⁡uf over all f m≤f≤M ‖f‖L1=2πs. In particular, this answers a question raised by J. Langford P. McDonald in [5]. also sources, which maximize/minimize at point x0∈[−π,π] same...

BACKGROUND Peritoneal infection and poor ultrafiltration continue to be the major causes of treatment failure in CAPD. The combined effects of peritonitis and the continuous exposure to dialysis fluid remain the most likely candidates affecting the peritoneum in the long term. The purpose of this study was to observe the effects of peritonitis and dialysis on longitudinal peritoneal function. ...

Background Hydrolysates are complex media supplements composed of many as well as different types of compounds. Within Frieslandcampina Domo’s Quality by Design project, detailed information of these compounds (annotation and quantification) has been generated. This was achieved for soy protein hydrolysates (Proyield Soy SE50MAF-UF) using metabolomics biochemical profiling. Biochemical profilin...

Background Earlier it was believed that uterine fluid (uf) or secretions are not relevant after the embryo implantation in humans. However, recent reports suggest that uterine secretions continue to play important role till the first trimester of human pregnancy. Evidences also suggest that uf mirrors endometrial functions or dysfunctions. Considering the relevance of uf in endometrial function...

پروفیل دما طی مرحله نمک پاشی، به دلیل اثر آن بر فعالیت میکروبی و آنزیمی نقش مهمی را در کیفیت پنیر بازی می کنند. در این تحقیق یک مدل سه بعدی برای توصیف انتقال حرارت در پنیر فراپالایش شده با استفاده از حل عددی قانون دوم فوریه با روش تفاضل محدود (مبنا شمای صریح) به عنوان تابعی از عوامل درونی (دما و ترکیب شیمیایی پنیر در هر نقطه در داخل پنیر) و عوامل بیرونی (دما، رطوبت نسبی و سرعت حرکت هوای محیط نگ...
