Adsorption Study using Water Hyacinth as an Adsorbent
Abstract: Heavy metals are widely used in numerous industries such as paints and pigments, glass production, mining operation, electroplating, battery manufacturing and textile industries. The significant losses of heavy metals occur during the manufacturing processes and these lost heavy metals are discharged in the effluent. As they move from one ecological trophic level to another, metallic species start damaging the ecosystem. They also become difficult to track as they move up …

Ethylene in Post-harvest Quality Management of Horticultural Crops: A Review
Abstract: Ethylene is a naturally occurring plant hormone that is produced by many fruits and vegetables. It initiates the ripening process when internal concentrations increase to 0.1 to 1.0 ppm. Externally applied ethylene can also initiate the ripening process in climacteric fruits. Ethylene is flammable at a concentration of 3.1–32% in air. The minimum flammable concentration of 3.1% or 31,000 ppm is about 200 times the concentration suggested for tomato ripening. …

Gear-Related Stress Analysis and Comparison Between the Fem and Agma Standards
Abstract: In many different devices, gears enable the efficient transfer of motion and torque. They are an essential component of modern mechanical power transmission systems. It has been demonstrated that bending and surface contact stresses at the gear tooth are the primary causes of gear failure, despite their widespread use. Too much stress can lead to tooth wear, pitting, or breakage, which can ultimately reduce the operating life and reliability of …

Aluminum and its Alloys to Recover from Corrosive Weather
Abstract: Corrosion is defined as deterioration of material, usually metal, because of reaction with its environment and which requires presence of an anode, a cathode, an electrolyte and an electrical circuit. Aluminum and its alloys are reactive to weather of exposure, e.g. ambient, acid and alkalis. Solid to pigments are prevented from corrosion by using inhibitors. Organic inhibitors are ever praised due to non-toxic performances. Basic processes are surface adsorption to …
