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...
Diet of mid-Atlantic Sowerby’s beaked whales Mesoplodon bidens
Pereira, José N.; Neves, Verónica C.; Clarke, D. C.; Prieto, Rui; Silva, Mónica A.; Cascão, Irma; Oliveira, Cláudia I.; Cruz, Maria J.Copyright © 2011 Elsevier Ltd. All rights reserved. ; The first mid-Atlantic diet of Mesoplodon beaked whales is presented, from ten Sowerby's Mesoplodon bidens stranded in the Azores region between 2002 and 2009. This doubles the worldwide number of stomachs sampled, and reveals new feeding habits for this species. The mean number of prey items per stomach was 85±89 (range: 12–238), with fish accounting for 9...
First report of Angiostrongylus cantonensis (Nematoda: Metastrongylidae) in Ach...
Maldonado Júnior,Arnaldo; Simões,Raquel O; Oliveira,Ana Paula M; Motta,Esther M; Fernandez,Mônica A; Pereira,Zilene M; Monteiro,Simone SThe rat lungworm Angiostrongylus cantonensis is a worldwide-distributed zoonotic nematode that can cause human eosinophilic meningoencephalitis. Here, for the first time, we report the isolation of A. cantonensis from Achatina fulica from two Brazilian states: Rio de Janeiro (specifically the municipalities of Barra do Piraí, situated at the Paraiba River Valley region and São Gonçalo, situated at the edge of G...
Significant anti-inflammatory properties of a copper(II) fenoprofenate complex ...
Agotegaray,Mariela A.; Boeris,Mónica A.; Quinzani,Oscar V.The synthesis, physicochemical characterization, anti-inflammatory properties and catecholase mimetic activity of the dinuclear complex of copper(II) with the non-steroidal anti-inflammatory drug Fenoprofen [2-(3-phenoxyphenyl)propionic acid] with formula [Cu2(fen)4(dmf)2] (fen = fenoprofenate anion, dmf = N,N-dimethylformamide) have been investigated. Results of spectroscopic analysis (FTIR and EPR) as well as...
On the multi-mode, multi-skill resource constrained project scheduling problem ...
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...
Designing a shipboard line transect survey to estimate cetacean abundance off t...
Faustino, Cláudia E. S.; Silva, Mónica A.; Marques, Tiago A.; Thomas, LenManagement schemes dedicated to the conservation of wildlife populations rely on the effective monitoring of population size, and this may require the accurate and precise estimation of this parameter. Line transect distance sampling can be an effective approach for estimating abundance. Little information is available regarding cetacean abundance in the Azores. This paper had two aims: 1) to design a line tran...
Role of the medulla oblongata in normal and high arterial blood pressure regula...
Cravo,Sergio L.; Campos,Ruy R.; Colombari,Eduardo; Sato,Mônica A.; Bergamaschi,Cássia M.; Pedrino,Gustavo R.; Ferreira-Neto,Marcos L.; Lopes,Oswaldo U.Several forms of experimental evidence gathered in the last 37 years have unequivocally established that the medulla oblongata harbors the main neural circuits responsible for generating the vasomotor tone and regulating arterial blood pressure. Our current understanding of this circuitry derives mainly from the studies of Pedro Guertzenstein, a former student who became Professor of Physiology at UNIFESP later...
Historic and recent occurrences of pinnipeds in the Archipelago of the Azores
Silva, Mónica A.; Brito, Cristina; Santos, Sara V.; Barreiros, João P.Copyright © 2009 by Walter de Gruyter GmbH. ; The Archipelago of the Azores (Portugal) is located between 37º and 41ºN and 25º and 31ºW and crosses the Mid-Atlantic Ridge. It is the most isolated archipelago in the Atlantic, situated 1600 km west of mainland Portugal and 3500 km from the eastern coast of the United States of America. At present, the only population of seals occurring in the Portuguese territor...
