When the traditional fuel reserves are limited and the environmental factors of these fuels are taken into consideration, the importance of renewable energy sources is increasing day by day. Especially, obtaining electricity from solar energy has become popula…

Here we discussed the electrical performance of Photovoltaic (PV) panels of natural dust accumulation by wind, bird droppings etc., over time which is of great importance especially for the areas where the rain density are high [1, 2]. In this study, the eff…

Superhydrophobic surfaces and materials received great attention of scientists and engineers due to their unwetting, self cleaning and antimicrobial properties. Hydrophobic surfaces are defined as having sessile water drop contact angle greater than 90°, while…

Günümüzde, enerji ihtiyacının karşılanmasında fosil yakıtların kullanımı sınırlı kaynakları ve çevresel etkileri nedeniyle sürdürülemez hale gelmiştir. Bu durum, temiz, çevreci ve sürdürülebilir alternatiflerin, özellikle güneş, rüzgâr ve biyokütle gibi yenile…

Pyrite is a mineral which has very low economic value although it is very common in the world. When the pyrite is concentrated together with the precious minerals, it produces a decrease in the grade and an increase in the smelting costs of the precious minera…

Yaşadığımız her ortamda gürültü, yankı ve çift ses vardır. Bu tip durumların yaşandığı en çok ortamların kapalı ortamlar olduğu ve kapalı ortamlarda ise topluluk alanlarının yoğunlukla bulunduğu ortamlarda sezilmiştir. İnsanların geniş topluluk olarak sergilen…

Today, rapid population growth and the development of technology have brought about the problem of waste. In order to solve this problem, it is first necessary to reduce the waste generation at the source. This can be achieved by raising awareness of the consu…

A universally applicable “optimal photobioreactor” design has yet to be established, as the success of such systems varies depending on the algal species used, environmental conditions, and intended applications. Meanwhile, the accelerating pace of climate cha…

Solar photovoltaic (PV) systems are widely adopted for sustainable energy production; however, physical defects such as glass breakage significantly reduce panel efficiency and system output. In this study, a real-world case analysis was conducted on a 1003 kW…

Artificial lighting is an important part of global electricity consumption. At office buildings, the energy consumed by artificial lighting can reach up to 40% of total energy consumption. This work is being done to find solutions to such problems with energy …

Teknolojinin hızla gelişmesiyle birlikte insanların konforlu yaşama olan ilgisi ve buna bağlı olarak da enerji tüketimi artmıştır. Enerji kullanımındaki artış dünya üzerinde enerji sorununa neden olmuş böylece enerji ihtiyacını karşılamak için farklı enerji ka…

Yapılan bu çalışmada, Ankara ili merkezinde bulunan bir kampüsün bazı binaların elektrik ihtiyacının fotovoltaik sistemlerle karşılanılmasının istenmesi durumunda tasarlanacak sistemden üretilebilecek enerji miktarının ve sistemin performans oranın simülasyon …

Sleep disorders such as insomnia, sleep bruxism, narcolepsy, and sleep-disordered breathing have different sleep quality parameters such as cyclic alternating pattern phases and A subtype phases. This study aims to analyze and predict the A phase subtypes from…

Introduction. Environmental pollution is a global ecological problem for today. Georgia is no exception. Among the many other contaminants, the environment here poses a serious threat to military wastes left by the former soviet Army, including toxic substan…

High patient satisfaction has become an area that is gaining importance with each passing day in terms of health institutions in today's world and in which satisfaction researches are conducted accordingly. Patient satisfaction is directly proportionate to the…

The high consumption of surfactants throughout the world (more than 15 million tons/year), together with their toxicity and negative effect on the self-purification capability of surface waters, make these synthetic organic compounds one of the main environmen…

In the United States, banking desert status is classified annually from that same year’s branch data, producing a contemporaneous snapshot of current access rather than a forecast of which communities are likely to change status next. This study tests whether …

Microalgae are recognized as environmentally sustainable and biologically renewable resources for the production of high-value products such as biomass, biofuels, dietary supplements, and pharmaceuticals. However, their large-scale cultivation is highly sensit…

2014-2017 dönemini kapsayan bu çalışmanın amacı İBBS düzey 2 kapsamında yer alan 26 bölgede mesleki eğitim kurslarının istihdam oranları üzerindeki etkisini analiz etmektir. Çalışmada GMM tahmincisine dayalı dinamik panel veri analizi kullanılmıştır. Modelde b…

This paper explores the possibilities of architectural design to benefit human condition, which encompasses physical environment of a safe life during the climate change era and predicted disasters. The first part deals with the problem of natural hazards and …
