The developments in internal combustion spark ignition (gasoline) engine technologies are in line with emission standards. The conversion systems which enable the use of LPG fuel in spark ignition (gasoline) engines renew themselves according to the developmen…

Gaz türbini motorları, yakıcılar, ısıtma ve soğutma sistemleri gibi birçok mühendislik uygulamasında geriye dönük adım akışı nedeniyle ayrılma ve yeniden birleşme bölgeleri meydana gelmektedir. Bu bölgelerin kontrolü, ısı ve kütle transferi miktarını artırmak …

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…

Demokrasi denilince akla gelen ilk unsur, halkın yönetime doğrudan ya da dolaylı olarak katılabildiği bir toplumsal düzendir. Bu açıdan yerleşim merkezlerinde kamusal hizmetleri gerçekleştirmek üzere yönetici ve üyeleri yerel halk tarafından seçilerek örgütlen…

This study was compiled from the results of various researches performed on using diethyl ether as a fuel or fuel additive in diesel engines. Three different techniques are used the reduction of the harmful exhaust emissions of diesel engines. The first tech…

In the present study, a model drug, with its low permeable and low aqueous soluble properties, was selected to produce microparticles using an anti-solvent precipitation technique with two different drugs: polymer (0.5, 1.0, w/v %) ratios. The characterization…

Anti-thyroid drugs are relatively simple molecules known as thionamides, which contain a sulfhydryl group and a thiourea moiety within a heterocyclic structure [1]. Methimazole (1-methyl-2-mercaptoimidazole) is widely used drug in medicine for treatment of hyp…

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…

The column materials in the form of monodisperse and porous particles were synthesized with regard to test their column performances in Ion Exchange Chromatography (IEC) mode. Particles in the form of poly(glycidil methacrylate-coethyleneglycol dimethacrylate)…

Open-finance platforms can combine models from different vendors while still concentrating capital in the same trade. Shared data, objectives, and representations make decision diversity the relevant object, rather than diversity of model names. We call loadin…

With the help of ability to imitate the biological nervous system, Spiking Neural Networks (SNNs) architectures have become popular recently. In order to benefit at the maximum level from the low power consumption, event-based structure and parallelization fea…

Schiff bases (known as imine or azomethine) exhibit interest as materials for wide spectrum applications, particularly as corrosion inhibitors, a metal ion complexing agents, in biological systems and  thermo-stable materials. Schiff bases are an important cla…

Elektronik kartlarda meydana gelen yüksek ısı üretimi, kart üzerindeki bileşenlerin çalışma performansını ve kullanım ömrünü etkileyen önemli bir parametredir. Bu nedenle cihazların mekanik tasarımları yapılırken soğutmayı sağlamaya yönelik çalışmalar yapılmal…

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…

Faz değişimli malzemeler, kristal yapıları sıcaklığa bağlı olarak değişen, kristal ve amorf fazlarında elektriksel ve optik özelliklerinde büyük farklılıklar gösteren malzemelerdir. Günümüzde, başta Flash ve DRAM hafıza teknolojilerine alternatif olarak görüle…

The hot-injection is one of the most used chemical synthesis methods to be able to produce nano- and/or micron sized particles in a liquid medium. Synthesis of nanoparticles of group II-VI semiconductors such as ZnO, ZnSe, CdSe and IV and V metals such as Pb…

In recent years, nanofluids, the dispersion of nanoparticles with sizes less than 100 nm in base fluids, have been attracted the interest of many researchers due to their capability of enhancing thermophysical properties. In this review paper, experimental s…
