Cellular phones are playing an important role in technological devices in today’s world. People start to use cellular phones at early ages. Even kids have their own cellular phones as a precaution for their security. However, researches evaluating long term …
ZnO nanopowders were synthesized via microwave assisted hydrothermal method at different precursor solution molarities. For this, the aqueous solutions of zinc aceatate dihydrate and sodium hydroxide were prepared at different molarity as precursor materials…
In many engineering applications such as aerospace, automotive and telecommunications, icing leads to mechanical and socio-economic problems such as efficiency reduction, decreased power transmission, security threat, material damage and energy waste. Theref…
İnşaat sektöründe, kurumsal sosyal sorumluluk (KSS / CSR-Corporate Social Responsibility) konusu giderek önem kazanmaktadır. Farklı ülkelerde farklı sektörlere de odaklanan KSS kavramı inşaat sektöründe genel olarak sürdürülebilirlik ekseninde ele alınmaktad…
In this work, the effects of bis (2-methoxy-4-allylphenyl) oxalate (I) on levitation (Fz) and lateral forces (Fx) of bulk MgB2 superconductor has been investigated and reported for the first time. All samples were prepared from magnesium powder (Mg, 99.8 %),…
In this talk, we work on a model of the prey-predator system to see the effect of system components on species distribution for both temporal and spatial structure. In some cases, changing environmental conditions results in extinction or leads the survival …
Multi-seeded YBCO superconductors (cylindrical size) 32 mm in diameter were fabricated by top-seeded melt growth (TSMG). Melt-processing was performed using a precursor containing 75 wt % of Y123 and 25 wt % of Y211 with 0.5 wt % of CeO2. Trapped magnetic fi…
In this study, natural colored (dark gray) wool and white angora fibers were firstly hand-spun and then hand knitted fabrics were produced from these yarns. Then, mass per unit area, air permeability and the hand of the fabrics were compared statistically. I…
İnsanlar arasındaki bilgi alışverişinin temeli olan iletişim yazıyla kalıcılık kazanmıştır. Yazı tarih öncesi dönemlerden günümüze içinde bulunulan dönemi aktarmak için bir köprü görevi üstlenmiştir. İlk yazının bulunuşundan günümüze pek çok aşamadan geçerek…
Canlılar koşma, yürüme ve emekleme gibi temel hareketlerini gerçekleştirmek için Merkezi Desen Üreteçleri olarak isimlendirilen ritmik desenler üreten sinir hücreleri topluluğuna sahiptir. Merkezi Desen Üreteçleri, canlıların bu temel hareketlerine ek olarak…
İçinde bulunduğumuz yüzyılda insan/çevre sağlığı çok büyük önem kazanmıştır. Bu hedefler kapsamında çok çeşitli (bitkisel, hayvansal, atıksal maddeler vb)’den yeni ahşap koruyucu çalışmaları devam edegelmektedir. Çay atıklarından (ISO 1574/ TS 1563) esasları…
Leadership is to orient and promote individuals for a specific purpose. Transformational leadership is the one who initiates change that makes employees believe in innovation and change. The transformation of the transformative leader in the formation of inn…
Forest workers generally work under severe conditions. Wood work; far from social spaces, weather conditions and rugged terrain. There is also no room for errors that are connected to a plan. Accident risk is high in forest workers. Accident risk must be hig…
Hydroxyapatite/polymer composites are promising materials for drug delivery applications. Studies focusing on the development of such composites are available in recent years, as using these materials as a carrier allows us to overcome the side affects of to…
Sanayi devriminden sonra ilk adı "Refah sekreterliği" olan personel yönetimi günümüzde bazı işletmelerde personel yönetimi, bazı işletmelerde ise insan kaynakları yönetimi adı altında faaliyetlerine devam etmektedir. Diğer işletmelerde olduğu gibi, konaklama…
Renewable energy can be produced by using kinetic energy of the flowing water such as rivers, ocean currents and tidal flows. The kinetic energy can be transformed to the power by hydrokinetic turbines. There are many different designs of hydrokinetic turbin…
In the 20th Century the technological developments also caused the change in the building systems as in every area of life. The plate systems, the shell systems, the space-cage systems, structure systems, the pneumatic systems and the cabled systems defined as…
In industrial robots, projected torque is increasing depending on the extending reach length and payload. This requires selection of powerful engines particularly on the second axis. Since arm's rigidity becomes more important as the expected positioning preci…
The concrete, which is an important building material, has a wide range of uses through its economic advantages and many other advantages. Economics, easy obtainable, long life, easy curing and workability are some of the advantages. Concrete is the most used …
