<p>Diesel engines cause major pollutants such as hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx). These emissions affect environmental systems lead to global warming climatic change effects. also humans health problems like lung cancer, breathing problems, headaches, etc. Hence, some necessary action has be taken minimise these pollutants. There are several steps ava...

Thanks to the Kroll process, metallic zirconium can be produced by means of a fairly complicated reduction process. In actual fact, the ore is found as a by-product when mining titanium and tin ore. Since 2003, the price of zirconium has more than doubled. This is the result of increasing demand and also the fact that a considerable amount of energy is needed to release zirconium from its chemi...

In this study, the initial temperature of (?) to (? + ?) phase transformation ?-quenched N36 zirconium alloy was determined using differential scanning calorimetry (DSC) and metallographic techniques. Diagnosis analysis difference between two techniques were also conducted. It found that transition temperature, obtained by techniques, lies in a range 710–715 °C. This value is lower than recorde...

Biofilms forming on the surface of biomaterials can cause intractable implant-related infections. Bacterial adherence and early biofilm formation are influenced by the type of biomaterial used and the physical characteristics of implant surface. In this in vitro research, we evaluated the ability of Staphylococcus epidermidis, the main pathogen in implant-related infections, to form biofilms on...
