Boron carbides are industrially well recognized for their low-density high-hardness properties and they are widely used for fabricating abrasives and shielding materials. However, the major weakness experienced in boron carbide is that it loses its mechanical strength after being impacted with a shock beyond its Hugoniot Elastic Limit (~17GPa). The...

Binlerce yıldır süregelen Türk Tarihi içinde deve son yüzyıla kadar çok önemli bir yer tutmuştur. Develer tarihte ulaşım, yük, binek, savaş, gıda ve spor amacı ile insanlığa hizmet etmiştir.. Ancak 20. Yüzyılda başlayan endüstrileşme ve modernleşme süreci içinde deve önemini kaybetmiş ve günümüzde sadece bir spor ve turizm malzemesi derecesine inmi...

This study deals to synthesize LiBH4 by means of mechano-chemical reaction, in which LiBO2 and MgH2 were utilized. In order to obtain 90% LiBH4 purity, optimum reaction conditions were analyzed at different values of reactant ratio and duration. In addition, commercial LiBH4 was hydrolyzed with CoI2 supported on activated carbon (AC). In order to f...

In this study, it is aimed that to reduce environmental effects of CO2 (as a greenhouse gas), to achieve absorption of CO2 in boron solutions and to yield a mixture product with boron compounds and the NaHCO3 which is raw material input especially in glass industry. In the laboratory scale experiments using autoclave, with different pressure, solid...

Aim of this paper is to summarize historical process of dog fighting which happens almost all over the World. The history of dog fighting reaches to ancient Roman and Chinese civilizations. Historians showed that large-scale human migration, development of trade, and gifts between royal courts of valuable fighting dogs facilitated the spread of fig...
