This study reviews the use of agricultural and agro-processing industry wastes as metal adsorbents from wastewater. Modified materials displayed better adsorption capacity and capability of some was comparable with that of commercial activated carbons and synthetic resins. Agricultural wastes are low-cost adsorbents and can be viable alternatives to activated carbon for treatment of metal-conta...

1 Overview Electricity generation from coal, natural gas, oil and nuclear sources involves the use of large volumes of process water. Two significant water-related issues confront the energy industry. The first involves biofouling of process surfaces and other power plant structures, leading to reduced energy efficiency and increased operational costs. A second challenge involves the accumulati...

In the aerospace industry, a significant effort is being made to replace metal components with more structurally efficient composite components to reduce mass, weight, and improve the reliability of aerospace fluid systems. Osprey Technologies and Convergence Engineering Corporation have teamed to develop various composite highpressure lines and fittings for composite-to-metal transition hardwa...

Metal coating, metal materials are of two or more layers. The coating metals are widely used in industry. These sheets or saving performance and cost effective solution or both the user. Performance coating metals according to usage in structural applications, settings thermal expansion of the thermo-mechanical control (thermostat), electrical, magnetic, corrosion resistant, flowering and decor...

ABSTRACT: In this paper we brie y describe the interaction of high power laser beam with metal material and its application in the engineering industry. We involve the mathematical model using the nite element method to solve the corresponding partial di erential equation of heat transfer numerically. For application in a laser industry we present results of some examples of heat eld distribution.

This article intends to evaluate the lung function and capacity to exercise and correlate both of them in metal industry workers.
