Enhanced Recovery After Surgery (ERAS) in Gynecologic Surgery: A Systematic Review

Enhanced recovery after surgery (ERAS) protocol aims to accelerate early recovery and improves postoperative patient outcomes. This protocol, which includes components such as reduction and prevention of postoperative complications, early mobilization, multimodal management of nausea and vomiting, positively affects surgical processes when used in patients undergoing gynaecological surgery. The aim of the present study was to use recent and relevant literature for examining the use of ERAS protocols in patients undergoing gynaecological surgery. Therefore, a systematic review was conducted to ...Daha fazlası

The Effect of Nutriton and Lifestyle on Age-related Macular Degeneration

Age-related macular degeneraton is an eye disease that is one of the biggest causes of blindness worldwide. Age-related macular degeneration is a complex and multifactorial disease. Although there are many risk factors both environmental and genetic such as ethnicity, age, genetics, family history, and oxidativestress, the most effective and modifiable risk factor in preventing age-related macular degeneration is smoking. In addition, the fact that nutrition is a potentially modifiable risk factor suggeststhat it may reduce the risk of age-related macular degeneration. In many epidemiological ...Daha fazlası

Biochemical Relationship Between Glucose-6-Phosphate Dehydrogenase Deficiency and COVID-19 And Effects Of Glutathione Supplements

ABSTRACT Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme in the pentose phosphate pathway involved in the production of the reduced form of nicotinamide adenine dinucleotide phosphate (NADPH). One of the most common inherited enzyme abnormalities is G6PD deficiency. G6PD enzyme deficiency facilitates human coronavirus infection due to glutathione (GSH) depletion. Depletion of glutathione due to blockage of the pentose phosphate pathway can hardly preserve the oxidative and anti-oxidative balance. GSH protects the body from the harmful effects of oxidative damage from excess reactive oxy ...Daha fazlası

Musculoskeletal Problems in Wheelchair Users: A Review Study

Mobility is the basic need for functionality in human life. Physically disabled people often require mobility aids and wheelchairs are the most commonly preferred assistive mobility devices for enhancing independent functional mobility. Today, powered and manual wheelchair technology is available. Manual wheelchair propulsion necessitates more repetitive loading, but because the human body is not designed for such movement, musculoskeletal and functional issues such as pain and joint limitation may arise among manual wheelchair users. They require more support from their spine, arm, elbow, and ...Daha fazlası

Simulation of three-dimensional slender droplet motion with adaptive mesh refinement Uyarlanabilir ağ yapısı ile üç boyutlu ince damla hareketi simülasyonu

Özdoğan, Mert

ABSTRACTWhile droplet moves over surfaces, various structures are observed cusp and corner formation, pearling, pinning/depinning, to name a few. We develop a finite element method (FEM) based solver to analyze three-dimensional motion of slender droplets over several substrates. To get accurate results within a feasible computation time, an adaptive mesh refinement (AMR) based on non-conformal, balanced and preload quadtree mesh structure is embedded within our quadratic FEM solver to focus our computational power on specific regions like contact lines. We validate our solver with the power-l ...Daha fazlası

Exhaust thermal energy recuperation in small gas turbine and turbojet engines Küçük gaz türbini ve turbojet motorlarında egzoz termal enerji geri kazanımı

Hakyemez Çatiner, Deniz

ÖZETHer geçen gün artan hava kirliliği ile önem kazanan karbondioksit emisyonunun azaltılmasına yönelik çalışmalar her alanda devam etmektedir. Elektrik üretimi, taşımacılık gibi hava kirliliğinin büyük kısmını oluşturan alanlarda gaz türbini kullanımı yaygındır. Gelişime açık bu motorlar ile verimi arttırmak ve yakıt tasarrufu sağlamak amacıyla çalışılan yöntemlerden biri olan reküperatör tasarımı bu tezin konusudur. Yer ve hava olmak üzere iki farklı mikro gas türbin motoru için borulu ısı değiştirici basınç kaybı ve sıcaklık artışı dikkate alınarak modellenmiştir. Hava tipi motorlarda alan ...Daha fazlası

Investigation of Manufacturing and Characterization of Radar Absorbing Hybrid Structures

Mohamed Yousef Ali Issa

Significant development of radar systems after World War II has led to studying the interaction between electromagnetic waves at radar frequencies and different materials. One perspective of these studies is to ascertain ways of decreasing reflected waves. However, the applications have not been limited only to defense applications but also to different fields where human beings are exposed to electromagnetic waves to avoid potential health effects due to exposure to electromagnetic waves. Since the discovery of radar systems, many studies have focused on electromagnetic radiation and absorbin ...Daha fazlası

Investigation of Optimal Solution Type and Volume for Inflation of Foley Catheter Balloon in Indwelling Urethral Catheterization

AYŞE AKBIYIK

Objective: In this study investigates the effect of the type and volume of solution used in inflation of the foley catheter balloon on the development of urine leakage around the catheter during indwelling urethral catheterization. Material and Method: This randomized controlled experimental study was conducted with 128 patients hospitalized in the intensive care unit and carried out between 2015 and 2019. In each study group, different types and volumes of the solution including 10 mL 0.9% sodium chloride, 15 mL 0.9% sodium chloride, 10 mL sterile distilled water, and 15 mL sterile distilled ...Daha fazlası
