This work analyzes how gases emitted during the manufacture of clinker vary in a cement plant using two types fuel: petroleum coke and unusable tires (UTs). study is based on case real time data more than 40 process variables. Gases are analyzed from points production process: sintering kiln, where main focus emissions to atmosphere by chimney, preheater. The variation CO NOx depending oxygen f...

high volume of waste tires, problems associated with their disposal, aesthetic problems, and the expansion and innovation of reuse of used tire products is being addressed aggressively. Chipped or shredded tires are being used for a wide variety of products, including playground covers, doormats, roadbed, fill, shoes, and aggregate substitute in septic system drainfields. This Analysis of Tire ...

The objective of this study was to compare the rolling resistance of four common manual wheelchair tires (two pneumatic and two airless solid) and the solid tires used on a commercially available force- and moment-sensing wheel. Coast-down tests were performed with a wheelchair positioned on a two-drum dynamometer. Within each of three load conditions, tire type had a significant effect on roll...

Gross domestic product (GDP) is the current dollar value of all final goods and services that are produced within a country within a given period of time. “Goods” are physical things that we consume (like a shirt) while “services” are intangible things that we consume but which are not necessarily physical (like education). “Final” means that intermediate goods are excluded from the calculation...

In the decade since used tires were identified as the mode of introduction of Aedes albopictus to the United States, similar infestations have been reported from 10 other countries in the Americas and 2 in Europe. Millions of used tires are still being traded throughout the world and although a few governments have implemented inspection procedures to prevent further introductions, these are un...

Present study investigates the ability of using damaged tires in field structural engineering. The proposed reinforcement material this represents an innovative approach to reuse strips extracted from used increase ultimate flexural capacity thin members, include timber beams and steel plates, satisfying clean environment economic considerations by consuming waste materials field. Results showe...

The efficacy of alpha-cypermethrin (Cyperthor) and lambda-cyhalothrin (Demand) to prevent mosquito larval colonization of water-containing receptacles was investigated using 2 differing applications in disused car tires in Darwin, Australia. Insecticide treatments were applied uniformly to the inside surfaces of 2 categories of tires: 1) dry tires that were partially filled with water 24 h afte...

The efficacy of maximum label rates of bifenthrin applications to dry tires to prevent Aedes mosquito breeding was investigated by field colonization and bioassay trials in shaded and unshaded locations. Aedes notoscriptus and Culex quinquefasciatus larvae were the most abundant species present in the field colonization trial. Colonization and survival of Ae. notoscriptus larvae to the late ins...

A sweep net with a flexible plastic frame was compared to a dipper for sampling efficacy for Aedes aegypti larvae in different-sized tires. When known numbers of mosquito larvae were introduced into tires, from 2 to 6.8 times more larvae were recovered by sweeping than by dipping. Sediment in the tires significantly reduced the recovery of larvae by both methods. Sampling efficacy was affected ...
