In the present study, the volatile compounds of essential oil of Lavandula stoechas L. (Lavender) was analysed by gas chromatography-mass spectrometry (GC-MS) using the Nist and Willey libraries. It was determined that the main components of L. stoechas were l…

The term structural optimization is commonly used for the optimization of engineering structures, such as building, automobile, or airplane structures for improved strength, stiffness properties, fatigue life and reduced weight or cost. Main purpose of this st…

Tüm dünyada evsel ve endüstriyel üretim işlemlerine bağlı olarak atık maddeler üretilmektedir. Atık maddelerin miktarı her geçen gün artmaktadır. Ayrıca atık maddelerin depo edileceği alanlar azalmakta ve tekrar kullanım alanları sınırlıdır. Atık maddeler çeşi…

Diesel engines have been preferable engines for heavy, medium and light duty vehicle applications due to their superior performance and fuel economy. However, concerns with their emissions, which are highly toxic air pollutants, put some limitations to their w…

In this article, the influence of the use of three different bricks on the building heat performance is compared for use on wall surfaces as a building construction element. At the beginning of the analysis, the thermal analysis of the building was carried out…

As the world is running out of fossil fuels and the environment is being seriously damaged by the combustion residuals of the internal combustion engines, the world countries have begun to search alternative ways for mobility. Lightweight electric vehicles w…

Microalgae are recognized as environmentally sustainable and biologically renewable resources for the production of high-value products such as biomass, biofuels, dietary supplements, and pharmaceuticals. However, their large-scale cultivation is highly sensit…

Kemik dokularındaki küçük hasarların bir kısmı rejenerasyon sayesinde kendiliğinden iyileşebilmesine rağmen büyük ölçekli hasarlarda bu durum zorlaşmaktadır. Kemiğin kendini yenilemede yetersiz kaldığı durumlarda farklı tedavi yöntemleri uygulanmaktadır. Otogr…

In this study, chicken and ground beef samples purchased from supermarkets and butchers in Samsun Province were analyzed for presence of Pseudomonas (P.) aeruginosa. In this case, classical culture technique were applied with molecular techniques. Isolation wa…

A total of 70 fish samples were randomly purchased from different butchers and supermarkets brands in Samsun Province, Turkey in 2018, and analysed for present of Pseudomonas (P.) aeruginosa. For that purpose, P.  aeruginosa isolation was carried out in conven…

Farklı prognostik biomarkerların prediktif önemi çeşitli kanser tiplerinde çalışılmıştır. Çalışmamızın amacı metastatik pankreas kanserli hastalarda tedavi öncesi CA19-9 değerlerinin risk derecesini ve prognostik önemini belirleyerek sağkalım ile ilişkisini or…

Nanotechnology is the science of controlling materials at the atomic and molecular levels. With the use of nanomaterials for diagnostic and therapeutic purposes, the field of molecular nanotechnology has emerged, enabling nanoelectronic biosensors and individu…

Akut Lenfoblastik Lösemi (ALL) genellikle 2-5 yaş arasındaki çocuklarda görülen, kemik iliğindeki beyaz kan hücrelerinin hızlı artışından ve şekilsel bozukluklarından kaynaklanan bir kanser türüdür. Tespit edilip tedavi sürecinin başlatılmadığı takdirde ölümle…

Using a lens to concentrate sunlight and focus it on smaller sized solar cells increases the system’s output power and in the same time decreases the cost by replacing much of the expensive semiconductor photovoltaic cells with the cheaper optics. But the conc…

The cell temperature of a photovoltaic (PV) module increases with increasing irradiation rate, and this increment adversely affects the output power or the electrical efficiency of the PV module. Therefore, in the present study, a series of experiments are p…

Plants encounter a variety of environmental stress factors that affect plant growth, fruit yield and quality. Stress factors cause physiological dysfunctions, ion imbalance, depression in photosynthesis, leading to growth reduction and decrease in fruit qual…

A theoretical design assessment performed here to evaluate the idea of utilizing wave energy in the Red sea to power electric-cargo ships, in the route between Port Sudan and Jeddah Islamic port. The calculated mean wave power in 2018 was (1.4 MW), five wave p…

Pyrite is a mineral which has very low economic value although it is very common in the world. When the pyrite is concentrated together with the precious minerals, it produces a decrease in the grade and an increase in the smelting costs of the precious minera…

Bu çalışmanın hedefi, silis kumu (SK) ve Termik Santralinden elde edilen uçucu kül (UK) kullanılarak geopolimer harç üretmektir. Bu çalışmada uçucu külü aktive etmek için çimento yerine, aktivatör (Na2SiO3 ve NaOH) ve uçucu kül (UK) birleştirilip bağlayıcı mad…

Dünya genelinde elektrik enerjisi tüketimi refah seviyesinin yükselmesi, nüfus artışı gibi faktörlere bağlı olarak sürekli artış göstermektedir. Enerji üretiminin büyük çoğunluğunu oluşturan fosil kaynaklı yakıtlar, atmosfere zarar veren sera gazlarının artı…
