Fish, a natural resource, has received great attention from all over the world. since it provides a cheap protein, employment and income to the millions of people for centuries. So fishermen, industrialist and multinationals are trying to exploit the marine resources to their maximum benefit by using modern craft, advance fishing equipments and efficient gear. Fishery resources in the open system particularly in oceans, were considered to be unlimited. However, recent developments in the innovation of efficient craft and gear using well tested material fitted with modern equipments that have greatly enhanced the mobility of craft, agility of gear and the ability of equipments to locate fishery resources have proved otherwise. Hence as the exploitation increases with more effort entering the fishery, the catch per unit of fishing effort starts to decline due to the limitness of the resources. The heavy fishing pressure in the recent past led to commercial extinction of a number of stocks such as. the North Sea herring, California sardine, Japanese Sardine and Peruvian anchovy (FAO. 1968: Gulland, 1974). In India, seer fish from Palk-Bay declined due to uncontrolled fishing (Devaraj 1983).

With the stabilization of world finfish catches in general, and the depletion of a number of fish stocks that used to support industrial-scale fisheries, increasing attention is now being paid, to the so-called unconventional marine resources, which include many species of cephalopods. One of such important cephalopod resource is the tropical Indo-Pacific pelagic oceanic squid Sthenoteuthis oualaniensis. It is the most abundant large sized squid in the Indo- Pacific region with an estimated biomass of 8-11 metric tons. However, its distribution, biology, life cycle and nutrient value in the south west coast of India are still poorly known. So any new information of this species in the waters off the south west coast of India has important scientific significance for effective and rational utilization of this Oceanic fishery resources, especially during the time of depletion of shallow water resources. In view of that this study investigated different aspects of the Sthenoteuthis oualaniensis, such as morphometry, growth, mortality, maturation, spawning, food, feeding and biochemical composition in the south west coast of India to understand its possible prospective importance for commercial fishing and management of its fishery

Este trabajo de grado es el producto de un fascinante recorrido intelectual que nos llevó del análisis del caso particular del trabajo de un médico empírico neogranadino, a la comprensión de un complejo universo social y político que tuvo gran influencia en el desarrollo del mundo médico de finales del siglo XVIII. Se trata de un ejercicio microhistórico que da cuenta de algunos aspectos claves de la medicina de este periodo a partir del análisis detallado y la descripción densa de los contenidos del libro Casos felices y auténticos de medicina(1830) de Domingo Rota (1752-18??)

La historia de la Independencia no cesa de escribirse. Su escritura se inició en el momento mismo de los acontecimientos. El Diario Político de Santafé de Bogotá, creado apenas unos días después del 20 de julio de 1810, se ocupó, casi exclusivamente, de contar y, por supuesto, de justificar el levantamiento de los criollos y la creación de la nueva Junta de Gobierno. Y aún más importante, en el temprano año 1825, el político e intelectual José Manuel Restrepo dio a conocer su Historia de la Revolución de Colombia, obra ambiciosa y sorprendente sobre el curso de los aconteceres que habían fracturado el imperio español y dado origen a las nuevas repúblicas. Obviamente, hoy la historia de la Independencia es algo mucho más complejo que un minucioso relato de las confrontaciones militares entre patriotas y realistas.
