Meeting the increasing energy need from fossil fuels such as coal, oil and natural gas caused the rapid depletion of natural resources. In a world where the need for energy is constantly increasing and resources are getting scarce, it is necessary to ensure the sustainability of energy. Clinker production is a process which require high amount of energy in manufacturing industry. The fact that energy is mostly obtained from coal, which is a non-renewable fuel, puts the future of the sustainability of cement production at risk. Alternative fuel usage plays the most important role in achieving m ...Daha fazlası
Determining water level changes in lakes is significant for sustainable water supply planning, flood control, water resource management, and economic development with ecosystem sustainability. Trend analysis is a commonly used tool for detecting changes in hydrologic time series of quantities such as lake level, precipitation and temperature. Trend analysis of meteorological variables is very important for assessing the long-term changes in lake levels. This study examines long-term changes in the lakes in the Central Anatolia region of Turkey. Kızören and Timraş sinkhole lakes and Lakes Tuz a ...Daha fazlası

Bu çalışmada, iki linkli düzlemsel bir robot manipülatörün bozucu etki altında yörünge kontrolü yapılmıştır. ADAMS yazılımı vasıtasıyla manipülatörün sanal bir prototipi oluşturulmuştur. Ayrıca, sistem için gerekli olan kontrolcü tasarımı MATLAB/Simulink ortamında gerçekleştirilmiştir. Sistemin simülasyonu ise MATLAB ve ADAMS yazılımlarının eş zamanlı olarak çalıştırılması ile gerçekleştirilmiştir. Robot manipülatör iki giriş ve dört çıkışa sahiptir. Girişler, her iki eklemin tahriki için gerekli olan motor torkları, çıkışlar ise her iki eklemin açıları ve uç elemanın konumunun x-y bileşenleri ...Daha fazlası

Trend analyses of meteorological variables play an important role in assessing the long-term changes in water levels for sustainable management of shallow lakes that are extremely vulnerable to climatic variations. Lake Mogan and Lake Eymir are shallow lakes offering aesthetic, recreational, and ecological resources. Trend analyses of monthly water levels and meteorological variables affecting lake levels were done by the Mann-Kendall (MK), Modified Mann-Kendall (MMK), Sen Trend (ST), and Linear trend (LT) methods. Trend analyses of monthly lake levels for both lakes revealed an increasing tre ...Daha fazlası
The purpose of this study was to investigate the effects of zinc and melatonin administration on interleukin-6, lipid peroxidation parameters, and element metabolism in DMBA-induced breast cancer in female rats. A total of 42 recently weaned Wistar rats were divided into 5 groups as follows: control (group 1),DMBA control (group 2),DMBA + zinc (group 3), DMBA + melatonin (group 4), and DMBA + melatonin and zinc (group 5). Malondialdehyde (MDA) and glutathione (GSH) levels in breast tissue and blood samples were determined via spectrophotometric methods. In addition, iron, magnesium, zinc, and ...Daha fazlası
Mass housing played an important role in changing the face of the cities. The Municipality Law No.5393 which gave the right to municipalities to build mass housing were factors that have accelerated the mass housing production. The main goal of local administrations is to build houses in the most rapid and economic way for group of people with low income. However, such production has posed problems in terms of quantity and quality. This research has been conducted to measure the satisfaction levels of users from mass housing projects which are implemented under the leadership of the municipali ...Daha fazlası
In this study, parametric optimization and sensitivity analysis of performance parameters were performed for the Organic Rankine Cycle (ORC) system at 120 °C heat source temperature. R1234ze, which is called the new-generation fluid, was used in the ORC design. Performance parameters have been selected considering Energy, Exergy, Economy (Turbine performance) and Environmental (Thermodynamic sustainability indices) factors. Six performance indices used in the orthogonal design with Taguchi-ANOVA. These are; thermal efficiency, turbine power, exergy efficiency, total irreversibility, Volume Flo ...Daha fazlası
One of the key challenges for nuclear physics today is to understand from frst principles the efective interaction between hadrons with diferent quark content. First successes have been achieved using techniques that solve the dynamics of quarks and gluons on discrete space-time lattices1,2 . Experimentally, the dynamics of the strong interaction have been studied by scattering hadrons of each other. Such scattering experiments are difcult or impossible for unstable hadrons3–6 and so high-quality measurements exist only for hadrons containing up and down quarks7 . Here we demonstrate that meas ...Daha fazlası
This study investigated the moderating effect of the self-regulation skills of children on their temperamental traits and on the mother’s parenting behaviour. The random sampling method was used to obtain the study’s participants: 253 children attending pre-school and their mothers. Research data was collected using the ‘The child behaviour list short form’ ‘Alabama Parenting Questionnaire’ ‘Self-regulation assessment’. The results reveal that diligent control and self-regulation skills directly influence positive parental behaviour and that the relationship between diligent control and positi ...Daha fazlası

During erosion tests of glass fibre/epoxy nanocomposites, an incubation period emerged because of the embedding of abrasive particles into the target material. In this study, the effect of this period on solid particle erosion behaviour was investigated for glass fibre/epoxy composites with the addition of nanoclay. The surface erosion characteristics of the composites were obtained by solid particle erosion tests using angular alumina particles with a size on the order of 400 μm as the erodent. The tests were conducted using impact velocities of ~23 or ~34 m/s and impingement angles of 30°, 6 ...Daha fazlası
Bu kitapta verilmek istenen ana fikir: önce kendimiz olmaktır. İnancımızla, örf-âdet ve ahlakımızla şahsiyetli olmak, daha sonra dünyaya açık olmaktır. Yani öğrenmeye, gelişmeye ve inkişaf etmeye teşne olabilmektir. Sabitemiz olmak kaydıyla dünyaya açık olmak gerekir. Savrulmadan, istikamet üzere mesafe almayı hedef seçerek ilerlemek bizim inancımızın temelidir. Doğru dil, doğru tarih ve doğru inanç şiarımız olmalıdır.

Particulate matter (PM), classified according to aerodynamic diameter, is one of the harmful pollutants causing health damaging effects. It is considered as cancerogenic by the World Health Organization (WHO) because of the substances found in the chemical composition of PM. In this study, short-term prediction of PM2.5 pollution at 1, 2 and 3 hours was modelled using deep learning methods. Three deep learning algorithms and the combination thereof were evaluated: Long-short term memory units (LSTM), recurrent neural networks (RNN) and gated recurrent unit (GRU).
