Nanoteknolojik çalışmalar bazı literatürlerde MÖ 2000 yıllara kadar dayandığı bildirilmiştir. Mısır uygarlığında ilk nano ürünler (mürekkep üretiminde) yalın düzeyde de olsa göze çarpmaktadır. Özellikle teknolojisinin gelişmesine paralel olarak günümüz bilim d…

Çalışmamızda Samsung PLCC4 LED ve elektronik bileşenlerinin jonksiyon sıcaklığı üzerinde via etkisi hesaplamalı akışkanlar mekaniği analizleri ile araştırılmıştır. Analizlerde FloEFD 17.4 hesaplamalı akışkanlar dinamiği ticari programı kullanılmıştır. Elektron…

Kanat uçağın kaldırma kuvveti üreten bileşenidir. Kanat uçağın mevcut ağırlığından dolayı meydana gelen yer çekimi kuvvetini, ürettiği kaldırma kuvveti ile yener ve uçağın havada kalmasını sağlar. Kanat sahip olduğu aerodinamik profiller sayesinde kaldırma kuv…

The photocatalytic degredation has received a great deal of attention due to its new technology for environmental pollution. Among photocatalytic semiconductors, titanium dioxide is known as a photocatalyst for the removal of environmental contaminants. In thi…

Forest functions traditionally included wood production, protection and forest recreation. The twofold role of forests as both sources and sinks of greenhouse gases makes their influence on the climate extremely significant. This fact has led to climate chan…

Yenilenebilir enerji kaynaklarından güneş enerjisiyle elektrik üretimi için yaygın olarak fotovoltaik (PV) modül kullanılmaktadır. Her sistem gibi bu sistemlerin de verimli olması istenir. Bir PV modülün elektriksel verimini düşürebilen pek çok faktör bulunm…

Solar energy from renewable energy sources can be used for different purposes. The most common areas of use are electricity generation and preparation of hot water. While photovoltaic (PV) modules are used for direct electricity production, commercial vacuum…

In this study, the effect of using a mixture of butanol and diesel fuel in a small diesel engine on engine performance and exhaust emissions is modeled. A comparison has been made with artificial neural networks, which is an up-to-date method, and multiple l…

This study was conducted at the Experimental area of Cukurova University in 2017 as a double crop. The objective of this study was to determinate the effect of Bacteria inoculation (Bradyrhizobium japonicum) prepared in different methods on yield and some ag…

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…

Palladium-catalyzed Suzuki Miyaura cross coupling reactions (SM Coupling) are made using organoboronic acid and halides. 9-(4-anthracene-9-yl-phenyl)-9H-carbazole (III) was synthesized by using Ullman and Suzuki coupling reactions. Structural analysis of the…

The metal ions accelerate drug action and efficiency of therapeutic compounds [1]. Metal complexes may inhibit the protein synthesis because of interference in the cellular respiration. Cancer is leading cause of fatality in recent years and remained as a ch…

Gelişen teknoloji ve artan nüfusun etkisiyle enerji tüketimi giderek artmaktadır ve bu durum tüm dünyada olduğu gibi ülkemizde de önemli bir problem olarak karşımıza çıkmaktadır. Fosil enerji kaynakları gün geçtikçe azalmaktadır ve bu nedenle araştırmacılar …

Cherry trees do not reproduce from seed. Desirable cultivars are grafted onto rootstocks which is generally clonally propagated. Many cherry rootstocks have been released around the world and a wide range of cherry rootstocks is available for growers. The cu…

Radyo ve Televizyon Üst Kurulu’nun derlediği verilere göre 2017 yılında Türk insanı, günlük 5 saat 30 dakika televizyon izleyerek dünyada birincidir. Türkiye’de ürünlerin tanıtımı ve marka bağlılığı yaratmanın en kolay ve hızlı yollarından biri, televizyon p…

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…

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…

Optimal operation of the power systems is very important. In this paper, a new approach for both the economic active power flow and active power loss minimization in multi-terminal HVDC systems is proposed. In the proposed optimization approach, system constra…

Optimal reactive power flow and economic power dispatch is very important in power systems. Optimal reactive power flow provides minimum active power loss and economic power dispatch provides minimum active power generation cost in power systems. This study pr…

The reuse of wastewater reduces both the consumption of freshwater resources and minimizes the environmental impact of discharged wastewater. Biological treatment technologies have been utilized in wastewater reclamation for over a century. Membrane Bioreactor…
