Nanomaterials including carbon nanotubes (CNTs) are employed in industrial applications such as supercapacito...

Biomaterials are engineering materials partially or completely derived and processed from biomass. It is believed that studies performed about formation and use of biomaterials will take place among materials of the future and expected to provide a major contribution to designs to be created. In our study, for preparation of bio basis films; first...

The agricultural machinery industry is a high health risk occupation. Companies should implement occupational health and safety management rules and regulations. These companies face a rapidly booming agricultural machinery sector and need the help of occupational health and safety management to achieve business goals. Being aware of the influentia...

The ability to supply energy in rural areas and in agricultural plants with renewable energy technologies, especially wind energy, is advantageous in terms of a sustainable environment and the increasing cost of energy. Today, wind turbines are used actively in many areas, some of which are for commercial purposes. Small-scale wind turbines that pr...

The experiments of this study were conducted in Deǧirmenalti{dotless} Campus of Nami{dotless}k Kemal University in Tekirdaǧ, a province in northwestern Turkey between 2005-2008. An anemograph system which can measure wind speed and wind direction at 2 m and 10 m heights was used in this study. The recorded data was transferred to computer environme...

The important effect of yoghurt on people's health caused increasing of many technological works and researches not only in our country but also all over the world. The environment in which yoghurt kept, may cause many sort of germs and contamination paths by the effects of some factors which are fairly similar to its own structure. These factors c...

The effects of chemical structure of the resin, reinforcement types, material thickness, and post-cure treatment on the mechanical properties of composite material were examined in this study. Composite materials were produced by combining chopped, woven, and felt glass fibers with thermoset plastic-based matrixes. Orthophtalic polyester (polives 7...
