The sensitivity and specificity of PCR, serology (ELISA) and lymphoproliferative response to Leishmania antigen for the detection of Leishmania infantum infection were evaluated in a cohort of 126 dogs exposed to natural infection in Brazil. For PCR, Leishmania DNA from bone-marrow was amplified with both minicircle and ribosomal primers. The infection(More)
The failure of control programs for visceral leishmaniasis (VL) that depend on elimination of infected dogs suggests that other reservoir hosts may participate in the transmission cycle. To determine whether persons infected with Leishmania chagasi can infect the vector sand fly, laboratory-reared Lutzomyia longipalpis were allowed to feed on Brazilian(More)
Five different fractions of the biodegradable municipal solid waste (BMSW) were evaluated as potential animal feedstuffs. For each source of waste (meat waste (MW), fish waste (FW), fruit and vegetables waste (FVW), restaurant waste (RW), household waste (HW)), samples were obtained from small shops (butchers, fishmongers, fruit and vegetable shops),(More)
Fruit-vegetable and fish wastes were evaluated as potential feedstuffs for growing-finishing pigs. Wastes were collected from shops in the city of Salamanca (Spain) and their nutritional composition, mineral content and digestibility were determined. The dry matter of the wastes under study was relatively low (12% for fruit-vegetable waste and 26% for fish(More)
BACKGROUND Studies for nine years in southern Spain on the olive moth, Prays oleae Bern., have tested the possibility of altering oviposition behaviour on newly formed olive fruits by means of a single ethylene application. RESULTS A single spraying of ethylene on the olive trees at the beginning of fruiting significantly decreased the olive moth egg(More)
A description is offered of microbiological characterization of the biodegradable fractions present in food wastes so that those fractions can be transformed in such a way that they will fulfil the specifications involved in their use as raw materials in other production areas. In this way the wastes can be converted into sub-products, hence minimizing the(More)
The design and implementation of static analyses that disambiguate pointers has been a focus of research since the early days of compiler construction. One of the challenges that arise in this context is the analysis of languages that support pointer arithmetics, such as C, C++ and assembly dialects. This paper contributes to solve this challenge. We start(More)
UML templates allow the specification of generic model elements that can be reproduced in domain models by means of the Bind relationship. Binding to a template encompasses the substitution of that template's parameters by compatible domain elements. The requirement of compatibility, however, is checked over by UML in a very permissive way. As a(More)
