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

The design, manufacturing and applications of a novel led-based phototherapy device Yeni Bir LED tabanlı fototerapi cihazının tasarımı, üretimi ve uygulamaları

Yaşar, Büşra

ABSTRACTJaundice is a very common disease in infants. It is caused by an increase in the level of bilirubin in the blood. Its incidence in newborns is around 60-70. When jaundice becomes pathological, it can cause much damage to the body: brain damage, vision loss, lung and kidney dysfunction, and even death. With the increase of bilirubin and its accumulation in the organs, irreversible damage occurs. There are different methods such as exchange transfusion, medication, and phototherapy to remove bilirubin from the environment. Blue light with a wavelength of 430-490 nm is required for light ...Daha fazlası

A Systematic Review on Intragastric Balloons and TransPyloric Shuttle in Obesity Treatment

Endoscopic bariatric procedures in the treatment of obesity have become widespread in recent years. In this systematic review, it was aimed to assess the role of intragastric balloons and transpyloric shuttle in the treatment of obesity. A comprehensive search was conducted using the search terms “Intragastric Balloon” and “TransPyloric Shuttle” in PubMed, Cochrane Library and Web of Science databases from 1st of December to 25th of December in 2020. Twenty-seven clinical studies (24 studies on intragastric balloons and 3 studies on transpyloric shuttle) were assessed. It is clear that both me ...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

ABSTRACTOsteomyelitis is a disease in which the process of bone destruction and loss is caused by microorganisms. Osteomyelitis has an increasing incidence rate that could cause chronic and acute infections. Bone infection has caused recurrent and permanent damage in 40 of the patients. 2-5 of infections caused by medical devices used in orthopedic surgical operations are osteomyelitis. More than half of osteomyelitis cases are caused by gram-positive bacteria such as Staphylococcus aureus and Staphylococcus epidermidis.

A comparison of the performances of conventional and low salinity water alternating gas injection for displacement of oil Petrolün geleneksel su gaz değişimli ötelenmesi ile az tuzlu su gaz değişimli ötelenmesi yöntemlerinin başarımlarının karşılaştırılması

Bucyanayandi, Emmanuel

ABSTRACTThe oil and natural gas reside in microscopic pores of subsurface rock layers called a reservoir rock. Besides there always at least two phases exist in oil and gas reservoirs. Therefore, the flow and displacement of oil into the production wells are influenced significantly by capillary forces. Due to the capillary and surface forces, the recovery of oil always remains at low percentages usually between 20 to 40. In order to increase the recovery factor several secondary and enhanced oil recovery techniques have been developed and implemented. The two secondary recovery methods namely ...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

The effect of local heating on the weld line formation in plastic ınjection molding of acrylonitrile butadiene styrene and glass fiber reinforced polypropylene Akrilonitril bütadien stiren ve cam elyaf takviyeli polipropilenin plastik enjeksiyon kalıplamasında lokal ısıtmanın birleşme izi oluşumuna etkisi

Güler, Muhsin Deniz

ABSTRACTIn this study, the effect of local heating on the weld line formation in a plastic injection mold was studied by using acrylonitrile butadiene styrene (ABS) and polypropylene 20 glass fiber (PP GF20) plastic material. An aluminum 6000 insert was fitted into the injection mold to set temperatures for local heating. The three parameters with three levels were selected for injection molding process parameters as insert temperature, mold temperature, and melt temperature and to produce mechanical tests specimens with weld lines and non-weld lines.
