Physicochemical properties of a mineral-based gasoline engine oil have been monitored at 0, 500, 1000, 2000, 3500, 6000, 8500, and 11500 kilometer of operation. Tracing has been performed by inductively coupled plasma and some other techniques. At each series of measurements, the concentrations of twenty four elements as well as physical properties such as: viscosity at 40 and 100°C; viscosity ...

Meghalaya is a state of the north eastern region which is recognized as a treasure of many valuable minerals. Mining operations were left to the local miners to take up coal mining as cottage industries since most of the coal deposits are small and isolated and were not amenable for scientific mining to be conducted in the organized sector. The study of soil physical properties has been done be...

Physical properties of fruits and vegetables are the subject of many researches because of its importance in designing of agricultural machinery. Banana fruit is one of important fruit. In this study some physical properties of banana fruit (Cavendish variety) were determined. Properties which were measured included weight of whole fruit peel and pulp weight, dimensions, surface area and projec...

utilization of the new compatibilizers to improve matrix/filler interface adhesion and also, nanoparticles to improve the properties of wpc products have always been of interest to researchers. in this study, the effect of oxidized polypropylene in solution phase as a comptibilizer and nanoclay particles on the physical and mechanical properties of wood fiber reinforced polypropylene composite ...

This paper presents a survey on soil Pb concentration around Sepahanshahr town located in vicinity of Isfahan. Due to the lack of regulation and environmental education and awareness, Sepahanshahr is now a rapid growing residential area suffering from the considerable consequences of poorly regulated mining activities operating in its vicinity. The aim of this study is to explore the spatial st...
