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....

Objective: The objective of this study was to develop the load-carrying capacity models tractor tires on rigid surface for both, radial and bias tires. Material Methods: In order functions, two tire constructional variables (section width overall diameter), inflation pressure, forward speed model were considered. developed in literature soil surfaces built some limited data as a result this, pr...

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...

Compared with pneumatic tires, non-pneumatic tires have incomparable performance, in terms of load bearing and safety. In this paper, the static characteristics pure longitudinal slip tire are studied by combining experiments simulations. The test results show that radial stiffness original structure is nonlinear, sliding seriously inconsistent, brakes very sensitive, driving slightly soft. A s...

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...

This study presents the results of research related to agriculture tire deformation under variable vertical load and inflation pressure. The objects were two tires same size different internal structures. Three levels pressure five used. loaded with each was scanned using 3D scanner—the effect this operation a three-dimensional image part (near place contact surface). next step creation horizon...
