Seconds later‚ Mount Pinatubo is part of a chain of composite volcanoes along the Luzon arc on the west coast of the island (area map). The arc of volcanoes is due to the subduction of the Manila The volcano experienced major eruptions approximately 500‚ 3000‚ and 5500 years ago. The events of the 1991 Mount Pinatubo eruption began in July

The effect of unmodified and titanate treated nano-CaCO3 on the microstructure as well as on the mechanical‚ barrier‚ optical properties of PVC films‚ prepared by solution casting method were studied. The tensile strength and barrier properties of nano-CaCO3/PVC increase with increasing loading of CaCO3 nanoparticles due to increased interfacial contact area and enhanced interfacial adhesion between CaCO3 nanoparticles and

digestive system‚ the earthworms eat the soil which has organic matter such as decaying vegetation or leaves. After organic matter is digested‚ the earthworm releases waste from their bodies called castings. Castings contain many nutrients that the plant can use. Some people even use earthworm castings as garden fertilizer this is one of the unique characteristics of the worm. Second‚ I will be talking about the grasshopper. The grasshopper moves by their back two legs‚ but cannot move unless their

WHITE-TOPPING A SOLUTION FOR DISTRESSED ROAD ABSTRACT India has one of the largest highway and road networks on the planet‚ third road network after United States and China. The road network has expanded from 0.4 million km in 1951 to about 3.32 million kilometres presently (2012)‚ a sevenfold increase‚ but traffic has increased 120 times. This leads to the deterioration of the surface of the asphalt pavements and a need to rehabilitate them before further damage could occur. Since the use of a

The foremost basic in structural engineering is the design of simple basic components and members of a building viz.‚ Slabs‚ Beams‚ Columns and Footings. In order to design them‚ it is important to first obtain the plan of the particular building that is‚ positioning of the particular rooms (Drawing room‚ bed room‚ kitchen toilet etc.) such that they serve their respective

1.0) INTRODUCTION The industrialized building system (IBS) can be generally interpreted as in which all building components such as floors‚ walls‚ columns‚ beams‚ and roofs are mass produced either in a factory or at site factory according to specifications with standardize shapes and dimensions and transported to the construction projects site to be assembled into a structure with minimal site wet work and erected on the site properly joined to form the final units.

EXECUTIVE SUMMARY The objective of this project is to study the dynamics of IR in SAIL‚ Bokaro Steel Plant and to analyze and reason out the possible causes for the same. Industrial Relations is the composite result of the attitudes and the approaches of the employers and the employees towards each other with regard to the planning‚ supervision‚ direction‚ and co-ordination with a minimum of human efforts and friction‚ with an animating spirit of co-operation‚ and with proper regard for the
