رآکتور مینیاتوری چشمه نوترونی یک تحقیقاتی از نوع مخزن-استخری است که در آن اورانیم با غنای بالا به‌عنوان سوخت، آب سبک خنک‌کننده و برلیوم بازتابنده استفاده ‌شده است. هنگام بهره­برداری دمای سیال افزایش می­یابد باعث ایجاد فیدبک منفی می‌شود. بر اثر تزریق راکتیویته عین حال یکی مزایای این خصلت ایمنی ذاتی است، اضافی دسترس کاهش‌یافته زمان عملکرد کاهش می‌یابد؛ بنابراین محدودیت­های اصلی MNSR کوتاه (حدود 5...

– We study the dynamics of a single polymer subject to thermal fluctuations in a linear shear flow. The polymer is modeled as a finitely extendable nonlinear elastic (FENE) dumbbell. Both orientation and elongation dynamics are investigated numerically as a function of the shear strength, by means of a new efficient integration algorithm. The results are in agreement with recent experiments. In...

Araştırmanın genel amacı; ilköğretim 4. ve 5. sınıf Fen Bilimleri dersinde araştırmaya dayalı öğrenme yaklaşımı modellerinden rehberli keşfetme modeli ile geleneksel öğretim yaklaşımına göre işlenen dersin, görme yetersizliği olan öğrencilerin fen dersine ilişkin tutumları arasında anlamlı bir farklılık olup olmadığının belirlenmesidir. Araştırmada deneysel araştırma desenlerinden çok denekli d...

Abstract The multiscale modeling of complex fluids under small and large amplitude oscillatory shear flow using non-linear kinetic transient network models is presented. kinetics microstates analogous to chemical kinetics, which defines the physical macromolecule interaction in a Newtonian fluid, concentration variable maximum length extension for each microstate. effect important parameters li...

The use of biological fluids such as saliva and cervical mucus as diagnostics for measurements of health status is becoming increasingly popular in the fields of biology and medecine, particularly given the non-invasiveness and ease of obtaining such fluids [39, 78]. In general, these biological fluids are polymeric, and as a result tend to be viscoelastic. However, as a result of protease and ...
