The noble gas plasmas have significant importance due to their high ionization energies requiring high temperature plasma investigation of neutral atom interactions through an analytical calculation of the second virial coefficient (SVC) with preferably Mors…
About 90% of world trade in transportation of goods is conducted via maritime transportation. An important operation area of maritime cargo transportation is ports. It is necessary to keep these ports secure where information and communication technologies a…
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 this study, hybrid composite structures were manufactured by vacuum assisted resin transfer molding method using three different woven fabrics (jute, E-glass and carbon) as the reinforcing material and polyester resin as the matrix material. All composite…
In the last century, there has been an ever-increasing demand for novel materials namely known as composites. Biological fibers are reinforcement materials of composite structures owing to their economic and ecological advantages. Among these fibers, plant f…
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 …
Oscillation theory for the solutions of Sturm-Liouville problems is one of the traditional trends in the qualitative theory of difierential equations. Its main goal is to establish su–cient conditions for the existence of oscillating solutions, to investigate…
It is well-known that the Sturm-Liouville type boundary value problems appears in solving many important problems in physics. For example, some problems of theory of elasticity in a half-strip ,the problems of theory of vibrations of an elastic cylinder redu…
A novel continues plasma reactor with rotating electrodes was designed and constructed to investigate methane decomposition to hydrogen and solid carbon. This new reactor structure causes stable operation. Hydrogen is main part of gaseous products which cont…
Complexity in the behavior of asphalt binders are further escalated with geopolymer (fly ash and the alkali liquid) modification thus, making it difficult to predict the performance of the binder accurately. This study employs artificial neural network model…
Boundary-value problems with eigenparameter dependent boundary conditions is one of the most extensively developing fields in pure and applied mathematics. First, we cite the works of Walter and Fulton, both of which have extensively bibliographies, a discus…
People has learned and has been developing agriculture for years. The surrounding land has become the best way to use as a result of years of observations. Over the centuries, cities have grown significantly and observable changes in land usage come up with …
Gelişim ve öğrenmenin hızlı olduğu, kişilik gelişiminin temellerinin atıldığı, temel beceri ve alışkanlıkların kazanıldığı okul öncesi dönemde çocuğa mahremiyet eğitiminin verilmesi önemlidir. Sağlıklı cinsel kimlik gelişiminde odak noktasını oluşturan mahre…
Amaç: Bu araştırma, kronik böbrek yetmezliği tanısı almış ve diyalize giren hastaların günlük yaşam aktivitelerinin değerlendirilmesi ve evde bakım gereksinimlerinin belirlenmesi amacıyla yapılmıştır. Materyal ve Metot: Kesitsel nitelikte yapılan araştırman…
Diyabet, bireyin ve ailesinin yaşamını çeşitli boyutları ile etkileyen, zorunlu yaşam tarzı değişikliklerini gerektiren, komplikasyonları nedeni ile yaşam kalitesini azaltan kronik bir hastalıktır. Tüm kronik hastalıklarda olduğu gibi sık görülen, tedavisi s…
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…
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…
Grape pomace, which is the byproduct of wine industry, consists the skin and seeds and occurs in a huge amounts. These waste products generally leads environmental pollution problems. The use of by-products of the wine processing industry as a source of functi…
Nowadays, rapid developments in the field of information technology and the use of the internet are becoming widespread depending on the living conditions we are in. The young population has become an important part of the lives of university students in parti…
