The radiation damage of proton beam on tissues and cells has attracted attention and the unique radiobiological effects make proton radiation a useful tool for the investigation of radiation damage mechanisms. Potential use of protons and other charged particles for cancer treatment offer several advantages over low LET radiation cancer therapy. In the present study the effect of different doses of gamma and proton beams from the Folded Tandem Ion Accelerator (FOTIA) on human tumor adeno carcinoma (HT 29) cells has been analysed using MTT (Thiazolyl Blue Tetrazolium Bromide) assay. The cell proliferation of HT 29 cells after irradiation has been anlysed using MTT assay after a post irradiation incubation of 72 hrs. The results of these investigations are presented and discussed in the paper.
There are four forms of capital which contributes to the success of any activity. They are financial capital, natural capital, physical capital and human capital. But apart from these four forms of capital, there is one more invisible form of capital that also contributes to the success of the activity/programme i.e. Social capital.

There are several causative factors of perpetuation of poverty including economic, social, psychological, political, structural, cultural, environmental and physical. Among these the psychological factors particularly behavioral paradigm focus on social psychological reasons influencing the penetration and perpetuation of poverty. As regards the livelihood models of the poor most of them are not sustainable due to the influence of the behavioral structures and patterns of the poor making them circle around the whirlpool of impoverishment. The subaltern culture force them to stick on to such delimiting behaviours whether it is fatalism, idleness, addiction habits, debts, extravagancy, lack of saving, having no future financial plan and a host of others. It is a conceptual paper to analyse the behavioral implications in the perpetuation of poverty and consequently failure in sustainability of livelihood means. Educational illiteracy, growing unemployment, geographical and climatic hit backs add to the menace. The paper calls for studies on prevailing structures and the need for social work intervention in terms of public participation towards social enterprises and social innovations to tackle the unsustainable nature of livelihood models of the poor. Extracts of interview with community leaders are added to support the theoretical framework. Social work methods, particularly community organization must focus upon this area to find suitable remedy.
