Responses of Some Cowpea Varieties to Two Striga Stains in Nigeria

The research was conducted in a greenhouse at the Internatinal Institute of Tropical Agriculture (IITA) to investigate the response of eighteen (18) cowpea varieties to two (2) Striga gesnerioides strain from Samaru of Kaduna Stete and Mingibir in Kano state Guinea and Sudan savannah of Northen Nigeria respectively. A total of 0.5g of the  available S. gesnerioides seed from each location was infested in eighteen pots. The dormancy was broken followed by planting of the Cowpea variety. It was observed that the angiospermic parasite response to some Cowpea varieties while some of the Striga was not sensitive to the root exudates. Samarium strains posses high number of Striga emergence but produce high yield. Compared to that of Mingibir. No any response in B301 in both the Samaru’s and Mingibir’s strains

COPEPODS IN AYIRAMTHENGU MANGROVE; KOLLAM

Mangrove ecosystems are considered to be the most productive and complex wetlands. Ayiramthengu is situated about 6 km west of Oachira town on the bank of the Kayamkulam estuary, its an important part of this estuary. Present study is aimed to analyse the copepod diversity and water quality parameters in this region. Because copepods are one of the important group in zooplankton , they are important food for fishes and its relation with water quality parameters is very important. Copepods were collected monthly using plankton net (60µ). During the whole study period (september 15 to august16) total 15 species of copepods are en counted belong in 3 order .6 species of cyclopoida,7 species calanoida and 2 species of Herpacticoida .Standard procedure are adopted for determination of physico-chemical parameters of water viz: , salinity, Temperature, DO, BOD, pH, are found thatinfluence the copepod diversity

STATUS OF PESTICIDE CONTAMINATION IN KAYAMKULAM ESTUARY WITH SPECIAL REFERENCE TO FISHES

World wide application of pesticide has drastically increased during the last two decades resulting with the changes in farming practices and enormously increasing intensive agriculture. This wide application of pesticides has resulted in the presence of their residues in various environmental matrices. It’s environmental tenacious, hoarding and their impacts in the ecosystem was incompetently perceive. These chemicals will finally enters into the aquatic system. Their lower persistent and soluble nature of many pesticide will impart their major portion to fishes, so the aim of the present study was the assessment of residues in water and fishes of the aquatic system it will throw back the present status of accumulation pesticides in the ecosystem. Result of the analysis showed that the fishes from the various study locations are fit for domestic consumptions, as the samples studied did not indicate any adverse or extremely high pesticide content that may affect the health of those consuming the fishes

A multilateral design methodology for development contexts : a framework for the Dharavi potters

Thesis (M.Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 2002.Page 83 blank.Includes bibliographical references (p. 80-82).The migration from rural areas to urban environments, and the continuous growth of the current population has caused an increasing shortage of low-in come urban housing in developing countries. In addition, the high cost of available housing has driven many in the lower income groups into squatter settlements in and along the periphery of urban developments. These squatter settlements are often the result of ineffectual and dysfunctional social and economic policy, compromised structures of governance, corrupt land markets, lack of equitable and humane regulation, and improper and inefficient finance scenarios. While poverty has many dimensions, urban poverty often has a broader meaning of cumulative deprivation, characterized by: squalid living conditions; risks to life and health from poor sanitation, air pollution, crime and violence, traffic accidents, and natural disasters; and the breakdown of traditional family and community safety nets. Rapid population increases within urban areas, crumbling infrastructure, growing inequalities between rich and poor, and insufficient urban services point to the need for a reevaluation of current models of urban development. Through an investigation of a multi-disciplinary approach to development, this project will identify the difficulties and potentials within the context of development in order to augment current design, planning, financing, and construction knowledge towards the creation of viable and sustainable architecture. The Khumbar Wada potters' community in Dharavi, Mumbai will be utilized to illustrate the potential for multi lateral approaches to go beyond the rhetoric that has compromised the discussion of architecture and its relationship to development work. The design will address development strategies and construction processes that express local conditions within the urban, architectural, and tectonic scales. Through the investigation and implementation of architectural infrastructure, the design will alleviate environmental, economic, and political constraints while accommodating local values. A potters' workshop will serve to illustrate the potential of a multi lateral design methodology. This thesis aims to suggest a framework for decision-making that can be used across various sectors and at multiple scales and the physical implementation of infrastructure that allows for the creation of more humane environments.by Amina S.
