In this study, the impregnation of Lareks wood with borax and nanotechnological varnish at various vacuum / diffusion times according to ASTM 1413-76 standards and the changes on technological properties were investigated. Pressure resistance properties were d…

Many structures, machinery, equipment, heritages, also socio-cultural systems may be subjected to the unfavourable impact caused by various disaster risks, such as flooding, heavy snow, earthquakes, landslides, hurricanes etc. For prevention and reduction of d…

Son yıllarda bilgi güvenliğini sağlamada biyometrik doğrulama sistemlerinin kullanımı yaygınlaşmış ve farklı biyometrikler ortaya atılmıştır. Çalışmamızda dokunmatik ekran üzerinde yapılan hareketlerden kaydırma hareketine bağlı olarak kişilerin ayırt edilmesi…

A serial hybrid optical amplifier composing of two amplification stages of erbium-doped fiber (EDF) amplifier covered C-band window and Raman fiber amplifier (RFA) covered L band window demonstrated. In this paper, the optimizations were done to obtain the opt…

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…

Bu çalışmada, DIN 1.2738 çeliği CVD kaplı karbür kesici takımlarla kuru kesme şartlarında tornalama deneylerine tabi tutulmuştur. Kesme parametreleri; üç farklı kesme hızı (150, 200, 250 m/dak), üç farklı ilerleme hızı (0,1, 0,15, 0,20 mm/dev) ve sabit kesme…

In the analysis of the flood routing problem, it is necessary to determine the change of the flood wave moving through the channel according to time and location, and in this context, nonlinear 3-parameter Muskingum model (NL-MUSK) is widely used. The parame…

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 %),…

A novel continues plasma reactor with rotating electrodes was designed and constructed to investigate methane decomposition to hydrogen and solid carbon. This new reactor structure causes stable operation. Hydrogen is main part of gaseous products which cont…

Complexity in the behavior of asphalt binders are further escalated with geopolymer (fly ash and the alkali liquid) modification thus, making it difficult to predict the performance of the binder accurately. This study employs artificial neural network model…

The dimensions of discrimination in Turkey was not discussed much. Furthermore, the policy made with it is not paid attention. The ideological tools and mass media also can be responsible for this issue. The emergence of discrimination should be a matter of …
