terms and conditions of current drinking water quality standards, including reducing the maximum arsenic concentration from 50 μgl-1 to 10 μgl-1 and predicted stricter standards in future, reveals the necessity for development of new technologies. this study aimed to prepare and evaluate a new nanocomposite membrane using graphene oxide (go) thin layer to remove arsenic (v) from water. to fabri...

In the current work, graphene oxide (GO) samples were prepared at room temperature from graphite flakes using a modified Hummer's method to produce metal-free electrocatalysts. The effect of the duration of the oxidation process on the structural, chemical and physical characteristics of the GO samples was evaluated using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), ...

Teknolojinin gelişimine paralel olarak konum bulma sistemleri çok önem kazanmıştır. Konum dış mekân ve iç diye temel iki sınıf altında toplanmıştır. Dış genellikle GPS sinyallerini aldığı için ortamda verimli bir şekilde çalışmamaktadır. İç gelişimini sürdürmektedir üzerine birçok çalışma yapılmaktadır. Bu çalışmada, mekan sistemi oluşturabilmek elektronik kart tasarımları gerçekleştirilmiştir....

D promising reforms following the civil rights movement of the 1960s and continuing through the 1970s, the progress of black men since the early 1980s has been relatively stagnant. The black-white gaps in high school graduation, earnings, and unemployment have improved little over the past 30 years. On some indicators, black men are doing steadily worse: faced with poor employment prospects, le...
