Algoritmo urza para el análisis de sensibilidad en problemas de programación lineal

Este artículo menciona que el algoritmo pretende llenar un hueco existente en los análisis de sensibilidad de la Programación Lineal. Estos análisis abarcan tradicionalmente a todos los coeficientes del sistema excepto a los coeficientes técnicos de las variables de la BASE, debido a la dificultad de calcular la inversa de ésta cuando se ha introducido un parámetro en uno de sus elementos.

Genetic improvement and utilisation of indigenous tilapia in southern Africa: final technical report, December 1st 1998 to June 31st, 2002

Mozambique tilapia (Oreochromis mossambicus) is an indigenous tilapia species in southern Africa, until now the majority of genetic research has been carried out on Asian species of tilapia but this project aims to look at this African species. Those most suited to further development in aquaculture in southern Africa have now been identified. The genetic characterisation of strains has been completed. This information has aided the choice of strains for use in small scale aquaculture and for genetically male tilapia (GMT) production. They will form the basis of future strategies for further genetic improvement, and management of genetic diversity of Mozambique tilapia. The information will also contribute towards responsible management and development of genetic resources, particularly with regard to indigenous species of tilapia. Good progress has been made with the adaptation and implementation of producing the supermale fish required to produce all male offspring, resulting in faster growing populations of tilapia. The presence of the project and its associated activity has been a catalyst for a surge in interest in tilapia culture throughout southern Africa. [PDF contains 183 pages]

Comunicação, educação e democracia no legislativo brasileiro

Esta publicação tem como objetivo ampliar o debate sobre a atuação do Legislativo no contexto social. As reflexões apresentadas pelos autores mostram como a disseminação de informações sobre o processo legislativo, seja pelas próprias instituições políticas, seja pelos atores sociais interessados em seus resultados, é essencial para o fortalecimento do sistema político representativo e, consequentemente, da própria democracia.

BECPELAG: Ein internationaler Workshop über biologische Schadstoffeffekte in pelagischen Ökosystemen

Im Februar 2001 begann unter der Schirmherrschaft des Internationalen Rates für Meeresforschung (ICES) und der Ozeanographie Kommission der UNESCO (IOC) der internationale Workshop Biological Effects of Contaminants in Pelagic Ecosystems, BECPELAG mit folgenden Zielen: • Untersuchungen über das Auftreten biologischer Effekte von Umweltschadstoffen auf Meeresorganismen in der Freiwasserzone (Pelagial) der Nordsee • Überprüfung von Methoden zur Erkennung von biologischen Schadstoffeffekten in pelagischen Organismen auf ihre Eignung für zukünftige Überwachungsprogramme

Fishermen cooperatives in the Green Revolution Programme

The aim of this study was to examine areas in which fishermen cooperatives can become involved and then suggest operational guidelines in order to increase fishermen income and also to make the Green Revolution Programme a success through increased production of fish. The paper enumerated different areas in which fishermen cooperatives can participate. These include: thrift and credits, thrift and savings, consumers and building cooperative societies. It is the belief of the author that the expansion of fishermen cooperatives into the areas mentioned in this paper can enable members to process and market their products more economically, buy supplies and equipment in large quantities and obtain lower cost credit

Length-weight relationship and the diets of Clarias lazera (Cuvier and Valenciennes), family Clariidae (Osteichthyes: Siluriformes) in Zaria, Nigeria

The length-weight relationship and the diets of Clarias lazera were investigated between July 1981 and June 1982. About 450 specimens were examined. The standard lengths of the fish ranged from 8.5 cm to 42.2 cm. Significant differences were found between the standard lengths of the males and females with the latter slightly shorter. Somatic weights varied between 10 g to 502 g. Length-weight regression analysis gave a "b" value of 3.02 for both males and females combined; thus indicating an isometric growth. Analysis of the food in the stomachs showed that the fish is an omnivore although, it fed more on insects and fish than other food items
