Deltamethrin and Permethrin in the liver and heart of Wistar rats submitted to ...
Santos,Mônica A. T; Rodrigues,Marili V. N; Áreas,Miguel A; Reyes,Felix G. RFor 28 days male Wistar rats were submitted to oral exposure with 1/10 of the LD50 value of permethrin (PMT) or deltamethrin (DMT). The aim of this study was to determine the residues of PMT and DMT in the liver and heart of the rats at the end of the exposure period, as well as to evaluate the effect of ingesting pectin and cellulose via the diet. The analytes were extracted with acetonitrile and the extracts ...
On the multi-mode, multi-skill resource constrained project scheduling problem ...
Santos, Mónica A.; Tereso, Anabela PereiraThis paper is concerned with an extension of the Resource-Constrained Project Scheduling Problem (RCPSP) which belongs to the class of the optimization scheduling problems with multi-level (or multi-mode) activities. We developed a practical tool, useful to represent multi-mode projects, and to find a solution for the problem on hand – select the best mode for each resource in each activity in order to minimize...
On the multi-mode, multi-skill resource constrained project scheduling problem ...
Santos, Mónica A.; Tereso, Anabela PereiraWe consider an extension of the Resource-Constrained Project Scheduling Problem (RCPSP) to multi-level (or multi-mode) activities. Each activity must be allocated exactly one unit of each required resource and the resource unit may be used at any of its specified levels. The processing time of an activity is given by the maximum of the durations that would result from a specific allocation of resources. The obj...

Santos, Mónica A.; Tereso, Anabela PereiraIn this paper we describe an extension of the Resource-Constrained Project Scheduling Problem (RCPSP). A literature review is presented to place our research in its proper context. The problem presented here belongs to the class of the optimization scheduling problems with multi-level (or multi-mode) activities. This means that the activities can be scheduled at different modes, each mode using a different reso...
Esterqueiras: avaliação físico-química e microbiológica do dejeto suíno armazenado
Santos,Mônica A. A. dos; Schmidt,Verônica; Bitencourt,Vanessa C.; Maroso,Michele T. D.Este trabalho avaliou a eficácia do armazenamento de dejetos de suínos por 120 dias, em três esterqueiras de propriedades suinícolas localizadas na bacia do lajeado Suruvi, município de Concórdia, região oeste de Santa Catarina. Os parâmetros analisados foram: decomposição do material carbonáceo, transformação de compostos nitrogenados, adsorção do fósforo e viabilidade de microrganismos patogênicos. Os resulta...
