TiO2 films have been deposited by sol gel spin coating technique onto glass and p-Si substrates. TiO2 films were prepared using two different sols. The physical properties of the TiO2 films were examined based on two different parameters. In the first study,…
In this work, the effects of bis (2-methoxy-4-allylphenyl) oxalate (I) on levitation (Fz) and lateral forces (Fx) of bulk MgB2 superconductor has been investigated and reported for the first time. All samples were prepared from magnesium powder (Mg, 99.8 %),…
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…
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…
Erosion is among the leading factors threatening our sources of soil and water. The use of soil susceptibility indices to determine erosion and risk situations has an important place especially in erosion studies. The susceptibility of soil to erosion is the…
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…
Developing technology in the manufacturing industry and the requirement of high precision parts reveals micro machining. It is possible to produce workpieces both at high speed and with high precision by means of micro-mechanical machining.The finite element m…
In the history of economic thought, different hypotheses have been formed which reveal the interaction between public expenditure and national income. These hypotheses can be decomposed according to their economic and political content. Political content hypot…
Many communication protocols are being used and standardized for the Internet of Things (IOT) infrastructure. At the forefront of the features expected from the protocols used is the efficient operation of a limited bandwidth and low bandwidth electronic devic…
In order to evaluate different modeling techniques for Unglazed Transpired Collectors (UTC), not only mathematical modeling method for UTC based on heat transfer expressions to estimate the various heat transfer coefficients for the UTC components and empirica…
To investigate how foreign trade deficits and budget deficits of Turkey navigated pre and post customs union (CU) with European Union. In the study, for the budget deficits (BD), General Directorate of Budget and Fiscal Control (BUMKO) and also for the foreign…
The particulate matters in ambient air were sampled in Denizli, Turkey in winter and spring using Bergerhoff Method. The average dry deposition fluxes were calculated as 152.1 ± 30.7 mg m-2 day-1 and 333.9 ± 214.2 mg m-2 day-1 in spring and winter, respectivel…
The quality control process for determining fabric faults causes high cost and time loss when performed with human eyes. Adding a real-time system to the fabric production mechanisms is very difficult to detect mistakes. In this study, 5 MP Raspberry Pi camera…
Maxwell denkleminin AV formülasyonu esas alınarak, zamana bağlı bir akım altında süperiletken telin elektromanyetik özelliklerini çözmek için yeni bir sayısal model geliştirilmiştir. Farklı akım genlikleri için alternatif akım (AA) kayıpları hesaplanmış ve iki…
In the world, constructions are mostly reinforced concrete framed structures with infill walls. Different reinforcement studies have been carried out on these existing structures in order to ensure the safety of life and property without heavy damage because o…
Structural health monitoring is an interdisciplinary field that enables early detection of undesirable situations such as damage or defects that occur in the structure or its components thanks to its ability to self-diagnosis. It is possible to use safer engin…
In recent years, significant improvements have been made in face transplants as well as organ transplants operations. It is also important to improve the adaptation process and quality of life of the patient after the transplant as well as the successful compl…
Elektrik sistemlerinin arızasız ve güvenli bir şekilde çalışabilmesi, akım ve gerilim gibi devre büyüklüklerin 50 Hz frekansta ve sinüsoidal formda olmasına bağlıdır. Bununla birlikte bir çok nedenlerden dolayı bu temel büyüklükler sinüsoidal özelliklerini k…
Milli Eğitim Bakanlığı tarafından en son 2017 yılında belirlenen öğretmen genel yeterlikleri, öğretmenlerin üniversite öğrenimleri süresince aldıkları eğitimle birebir ilişkili olmalıdır. Ayrıca branş bazlı olarak bakıldığında her branşın kendine ait yeterli…
