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 ...

OBJECTIVE To evaluate the monthly frequency of larvae and pupae of Aedes albopictus, Aedes aegypti and other mosquitoe species in tires, and the influence of environmental factors on that. METHODS The immature stages of mosquitoes were collected monthly from four tires in the municipality of Nova Iguaçu, Brazil, from November 1997 to October 1998. The following variables were measured: rainfa...

In 1985, the scrap tire industry was created when Minnesota became the first state to develop specific legislation and regulations for scrap tires. Up to that time, many scrap tires, like most solid and household wastes, went into the l1)unicipal dump. Those tires not placed in the dump went into stock piles, some of which still exist today. Prior to 1985, few, ifany scrap tires were processed....

This paper discusses the recognition of raised alphanumeric markings on rubber tires for their classification. The main subject of this paper is the finding, separating, and recognizing the characters raised on rubber tires, which is different from the recognition of printed characters. The complter simulation result shows that the proposed system can be successfully applied to the industrial a...

Solid waste management is one of the major environmental concern in the United States. Over 5 billion tons of non-hazardous solid waste materials are generated in US each year. Out of which more than 273 million scrap tires (approximately 3.6 million tons) are generated each year. In addition to this, about 3 billion tires are stockpiled. Several studies have been carried out to reuse scrap tir...

Walking ability is essential for the elderly/the disabled’s self-supported daily life. Currently the development of various robotic aids or devices for helping the elderly’s walking has attracted many researcher’s attentions. Guidecane ((Ulrich & Borenstein, 2001)), PAM-AID ((Lacey & Dawson-Howe, 1998)), Care-O-bot ((Graf et al., 2004)), PAMM ((S. Dubowsky, 2000)), and etc, are developed for in...
