Utilizing oil extracted from waste engine oil and waste plastics, by pyrolysis, as a filel for internal combustion engines has been demonstrated to be one of the best available waste management methods. separate blends of fuel from waste engine oil and waste plastic oil was prepared by mixing with diesel and experimental investigation is conducted to study engine performance, combustion and exhaust emissions. It is observed that carbon monoxide （CO） emission increases by 50% for 50% waste plastic oil （50WpO：50D） and by 58% for 50% waste engine oil （50WEO：50D） at full load as compared to diesel. Unburnt hydrocarbon （HC） emission increases by 16% for 50WpO：50D and by 32% for 50WEO：50D as compared to diesel at maximum load. smoke is fotmd to decrease at all loading conditions for 50WpO：50D operation, but it is comparatively higher for 50WEO：50D operation. 50WpO：50D operation shows higher brake thermal efficiency for all loads as compared to 50WEO：50D and diesel fuel operation. Exhaust gas temperature is higher at all loads tbr 50WpO：50D and 50WEO：50D as compared to diesel fuel operation.

We report here for the first time the composition and mineralogical studies on a new meteorite, which fell in Dhayala ki Chappar （24°58°n, 73° 48°27°E） 5 km nW of nathdwara in south Rajasthan, India, on Dec. 25th, 2012. Mineralogical and compositional studies were carried out on a representative piece of the nathdwara meteorite sample. The mineralogical composition of the meteorite has been found to be olivine （42 45 vol.%）, feldspar （10-15 vol.%）, orthopyroxene （23-25 vol.%）, troilite （6 8 vol.%）, and titanium bearing minerals （6-8 vol.%）. Our investigations show that the nathdwara meteorite belongs to H6 group of ordinary chondrites.

The laser-induced relativistic shock waves are described. The shock waves can be created directly by a high irradiance laser or indirectly by a laser acceleration of a foil that collides with a second static foil. A special case of interest is the creation of laser-induced fusion where the created alpha particles create a detonation wave. A novel application is suggested with the shock wave or the detonation wave to ignite a pre-compressed target. In particular, the deuterium–tritium fusion is considered. It is suggested that the collision of two laser accelerated foils might serve as a novel relativistic accelerator for bulk material collisions.
