Yeşil bina sertifika sistemleri, sürdürülebilir binaları tanımlamak ve belli kriterlere göre sınıflandırmak için en geçerli yöntemdir. Şu an ülkemizde bulunan yeşil bina sayısı günden güne artmakta ve ulusal bir sertifika sistemimiz olmadığından dünyada en ç…
Bu çalışmada trafo merkezi ve yüksek gerilim hatları etrafında halkın maruz kaldığı manyetik alan seviyelerinin belirlenmesi amacıyla Konya’da manyetik akı yoğunluğu değerleri ölçülmüştür. Ölçümler yüksek gerilim hattı ve trafo merkezine farklı uzaklıklarda …
Childhood is a sensitive period in which human life is shaped and the environment in which the child interacts is of great importance. Since the child has a constantly evolving and changing structure, its furniture needs to be changed in terms of both functi…
Bir işletmenin katma değer yaratan faaliyetlerinin yaklaşık yarısı, araştırma, yenilik, verimlilik, istihdam yaratma, ithalat ve ihracat gibi kavramlarda anahtar rol oynamaktadır. Dolayısıyla İşletmelerin küresel rekabette varlığını sürdürebilmesi, endüstris…
In this study, the development of the compressive strength obtained by heat-activation of the mortar produced with Fclass fly ash and sodium meta-silicate was investigated. In the study, mortar samples were produced using F class fly ash, standard Rilem sand a…
Education is important for us to our life and our future. Education is versatile so the relationship with social capital hac become inevitable. Lack of social capital is a big problem for employment like education.the development of social capital for edutaion…
In this paper, a different approach for the optimal active power flow solution in multi-terminal HVDC systems to minimize total active power generation cost is proposed. System constraints for all of the control and state variables of both AC and DC systems ar…
In the ceramic sanitaryware sector two different slips are used for different products. These slips are VC (vitreous china) and fine fire clay (FFC). Large-sized products must have low firing deformation, like washbasin, shower tray etc. are produced from FFC …
The dams built for the purposes of electricity generation, domestic and irrigation water supply, flood control, etc., make a great contribution to the region and country's economy. For all these purposes, dam construction is very difficult and costly. In addit…
This study aimed to develop natural dyes for wood material that are harmless to humans and the environment. For this purpose, a tea stain and polyurethane single- and double-component water based varnish were applied by brush on the wood surfaces of pine (Pinu…
Phthalocyanines (Pcs) have many uses in advanced technology. In recent years, the applications of MPc complexes have expanded to fields such as photodynamic therapy (PDT) photodetectors, photoconductive agents in photocopiers, and electrocatalysts, but these c…
Selection of floor insulation and flooring material is important in terms of providing electricity and safety of persons in electrical networks and electrical utility vehicle. The goal of a safe ground is to ensure the safety of people and the electrical syste…
Mining environments have faced with serious fatalities related to works, workplaces and workers as a consequence of their accident-prone processes. Underground mining stands in the first place in terms of being a hazardous industry worldwide. Due to risks invo…
Until the last four decades, number of teachers have been insufficient in public schools of Turkey. Nowadays, there is still an overall imbalance between supply and demand for teachers, because teacher supply is in surplus. It is associated with engaging short…
This study is related with numerical modeling of a Francis turbine draft tube. In order to reveal this relationship, a real Francis turbine model test results are used as inputs of the computational fluid dynamics (CFD) study. Firstly, the flow in divergent ch…
Plasticity index is one of the most important parameters affecting the behavior of fine-grained soils under monotonic and dynamic loads. Besides, various correlations between plasticity index and strength properties of fine grained soils can be obtained depend…
The sun's rays, which are our source of life, give us pleasure to enjoy in the winter and spring, but in the summer, the steep and scorching rays disturb us all. For this reason, it is observed that on average, 52% of the cooling load needed in the calculation…
Stress is a condition was effect whole body. The present study was carried out to investigate stress and its effect on oxygen saturation in peri-exam period. There were 91 students out of which 83 participated (19.2±1.0 year old) in the study.The oxygen satura…
In this study, the experimental application of polymer electrolyte membrane fuel cell (PEM-FC) with dc-dc boost converter is realized for compact design of electric vehicle (eV). The PEM-FC is an electro-chemical device which combines hydrogen with oxygen to p…
