In this paper, heat transfer of a multi-tube exchanger filled with RT82, fins, and nanoparticles is investigated using numerical modeling. There are four fluid (HTF) tubes embedded in shell that contains PCM. The PCM under simultaneous charging discharging (SCD) conditions caused by pumping two hot fluids (HHTF) cold (CHTF). arrangement these HHTFs CHTFs, as geometrical factors, compared each o...

The excessive amounts of parathyroid hormone in secondary hyperparathyroidism (SHPTH) is suggested to interfere with normal erythropoiesis. In SHPTH, during chronic renal failure, due to the impairment of erythropoietin synthesis, this effect is more pronounced. In the present study the role of secondary hyperparathyroidism in the severity of anemia was evaluated in hemodialysis patients (n=36;...

This paper presents the formulation, validation, and application of a spectral/hp algorithm for numerical solution of the Navier–Stokes and heat/scalar transport equations in arbitrarily moving complex geometries. The new spectral element algorithm is based on the arbitrary Lagrangian Eulerian formulation and utilizes modal expansion of Jacobi polynomials in mixed triangular and quadrilateral e...

Madde kullanımı ve bağımlılığı, birçok ülkede olduğu gibi Türkiye’de de özellikle gençler arasında hızla artmaktadır. Zira Afganistan’da üretilip İran’a gönderilen maddelerin çoğu, Türkiye’nin içinde yer aldığı “Balkan Rotası” üzerinden Avrupa’ya Avrupa’da üretilen sentetik opioidler Türkiye Ortadoğu ülkelerine sevk edilmektedir. bu transferin gerçekleştiği illerin başında ise İran’dan gelen uy...

Bu çalışmada gelişmekte olan ülkelerde Covid-19 pandemisi süresince uygulanan sosyal koruma önlemleri üzerine bir analiz gerçekleştirilmiştir. Gelişmekte pandemi benzeri krizde kapsamlı sağlayan politi-kaların ne olduğu sorusuna yanıt aranmıştır. İlk olarak, Uluslararası Çalışma Örgütü’nün (ILO) işsizlik yardımı verileri ve Dünya Bankası’nın (WB) ülkelerin güvenlik önlemlerine ilişkin Dayanıklı...

There is strong evidence to indicate that proteins of the synaptobrevin family play a key role in exocytosis. Synaptobrevin 1 and 2 are expressed at high concentration in brain where they are localized on synaptic vesicles. Cellubrevin, a very similar protein, has a widespread tissue distribution and in fibroblasts is localized on endosome-derived, transferin receptor-positive vesicles. Since b...

The complexes of chromium(III) ion formed by salicylic acid, SA(H(2)L), and its derivatives (H(2)L): 5-nitrosalicylic acid (5-NSA), 5-sulphosalicylic acid (5-SSA) were investigated by means of potentiometry and spectroscopy, at 25 degrees C and in ionic strength of 0.1 M KNO(3) and 0.1 M KCl, respectively. Over the acidic pH range, the coordination of Cr(III) ion to SA and its derivatives in 1 ...

It was shown that ointments containing silver compounds delay wound healing and increase the risk of hypertrophic scarring in burned patients. The aim of the study was to establish the influence of AgNO3 on cell viability and apoptosis of keratinocytes and fibroblasts in vitro. Foreskin was used to establish primary human keratinocyte and fibroblasts cell cultures. Keratynocytes grew in DMEM/Ha...

According to the classification of placental types among animals, the transfer of iron through the placenta can occur via: absorption connected to transferin through the outer surface of the trophoblast in direct contact with circulating maternal blood; absorption of the erythrocytes by the chorionic epithelium in direct contact with accumulation of blood extravased from haemotophagous areas; a...
