The Taxpayer Relief Act of 1997 (TRA97) significantly changed the tax treatment of housing capital gains in the United States. Before 1997, homeowners were subject to capital gains taxation when they sold their houses unless they purchased replacement homes of equal or greater value.

Sustained malaria control is underway using a combination of vector control, prompt diagnosis and treatment of malaria cases. Progress is excellent, but for long-term control, low-cost, sustainable tools that supplement existing control programs are needed. Conventional vector control tools such as indoor residual spraying and house screening are highly effective, but difficult to deliver in ru...

Analysis of field data collected over several years in three poultry housing systems (narrow caged-layer houses, high-rise caged-layer houses, and broiler-breeder layer houses) indicated that the baited jug-trap was a reliable method of sampling house flies, Musca domestica L.; sticky ribbons provided additional information on two other fly species. Relative frequency of house fly capture indic...

Weekly releases ofMuscidifurax raptorellusKogan and Legner and Spalangia cameroni Perkins were made for 12 wk after house cleanouts in Florida pullet houses in either spring/summer (MayÐAugust) or fall (SeptemberÐDecember). Releases were made by weekly placement of 62,500 and 85,000 pupae parasitized by M. raptorellus and S. cameroni, respectively, which produced an average of 79,049 and 32,841...

Introduction The development of a sustainable, profitable, and competitive egg-production system is becoming a challenging issue facing the laying-hen industry. The excretion and volatilization of nitrogen and the emission of volatile organic compounds of dietary origin are responsible for a large part of the environmental issues that have risen from the intensive poultry production. Especially...

American Cutaneous Leishmaniasis, ACL, is a zoonotic disease with a large richness of co-occurring vector species in transmission foci. Here, we describe changes in patterns of phlebotomine sand fly (Diptera: Psychodidae: Phlebotominae) species composition at the village of Trinidad de Las Minas, Capira, Panamá, a hyperendemic focus of ACL transmission, subjected to a vector control interventio...

Existing homes for senior population may not be safe because many injuries occur due to poor accessibility and design compatibility. Thus, Universal Design (UD) becomes more relevant, especially if it incorporates the principles of sustainability. Yet, adopting houses of this type requires detailed evaluation of their costs and benefits in a simple and efficient manner. The Building Information...

The invasion of a secondary forest within the city of Rio de Janeiro by Aedes aegypti and Ae. albopictus was evaluated from July 1997 to June 1998 through collections of immature stages in ovitraps set at 1 m, 10 m, 100 m, 500 m, and 1,000 m into the forest from houses on the periphery. Both mosquito species were much more abundant close to houses (1-10 m). Aedes aegypti was not collected beyon...
