Gene selection is an important issue in analyzing multiclass micro array data. Those genes which help sample classification are selected from the original set of genes and the redundant gene expression data are eliminated. In this paper the important genes are selected by updating the weights & by minimizing the error. The minimizations of errors are done by Hopfield network consisting of four perceptron model or modules. A dataset was taken as input and is multiplied by some random weights to get the output. This process continues in an iterative way until the error is minimized. Based on these minimal errors, the best gene expression from the dataset is selected.

With the outbreak of industrial revolution the trend in large scale production for domestic as well as foreign market has set in. Developed countries can invest huge money in design and R&D to develop their products, but due to trade liberalization the competition becomes stiffer and under developed countries are facing lot of problems to meet the standards for global markets.- Study on Arsenic Mobility through Groundwater Irrigation in a Part of Chakdah Block, Nadia District, West Bengal

Like the revolution of the earth round the sun, the God-gifted natural freshwater resource is supposed to be used by the human beings for drinking as well as irrigation purpose. This vital resource makes up 60 percent of the human body. But groundwater has been losing its potability not only due to various anthropogenic activities but also its huge development in irrigation sector. In recent-past, Arsenic (As) exposure in human beings from groundwater has been reported and millions of people have been suffering from arsenicosis both in many parts of developing and developed countries.
India is a land of agriculture including West Bengal. Agriculture is the main occupation of the villagers in West Bengal and large source of economy. However the cultivation is mostly seasonal and generally depends on grace of nature. The high As groundwater is an important issue in rural Bengal, where due to insufficient rainwater in pre-monsoon season, the local farmers are being compelled to execute by withdrawing groundwater by installing irrigation wells. Hence large-scale groundwater development for irrigation purposes has been practiced to aid in the summer crops production in West Bengal.
The present study involves the monitoring of As mobilization through irrigation groundwater in a selected area-of-interest in Chakdah block of Nadia district, West Bengal. Chemical quality parameters of groundwater have been determined through testing of collected groundwater samples during pre-monsoon season. It has been found that the As concentration of the maximum irrigation wells are relatively high exceeding the WHO's recommended safe limit (i.e. 10μg/L of As), indicating the possible chances of As migration through crops and food chain.
Surface driven fresh organic matter may have some important role in mobilizing As in groundwater. In this context, the role of iron mineralogy and anoxic environment in the shallow aquifer zone are also important factors. Therefore, groundwater irrigation beneficiary communities in this area should aware about mobility of As in groundwater for their agri-food security.

Information foundations are the most important and valuable feature in the field of information science which are mainly dedicated to several information activities ranging from collection, selection, organisation, processing, management, and dissemination of information to several clients and users directly or indirectly. Information science and documentation are main aim for information foundations of all types. Information foundations such as information centre, data centre, use so many electronic products which release many harmful chemicals and products which are against environment and human being. Hence possibilities of using alternative technologies may reduce such problem in many ways as far as better and sophisticated environment is concerned. This paper talks about information foundations, including its types and features and ways to integrate computing and allied technologies to promote such services.Keywords
