Water Pumps

Solar (photovoltaic) powered water pumps could be a real instrument for the alleviation of water related deaths and illnesses in developing countries through the provision of clean water. However, despite the benefits that access to sustainable potable water supplies can bring, solar powered water pumps have a long way to go before they even begin to meet the needs of those who could use them. This paper addresses some of the complex, inter-related social and technical issues that have prevented solar powered water pumping from reaching its full potential and shows how future efforts should be directed in order to respond to these issues.

Alternative Solutions

Water is a major component of the environment, covering 70% of the earth's total surface area. Yet, the demand for potable water in most locations remains high. Alternative solutions have been put in place coupled with the energy crisis for power sources to the existing hydro and thermal plant to ensure constant pumping of water. This paper presents a feasible solution in the quest to make potable water more available in deprived areas - design of a wind-powered system to drive water pumps. Unlike other existing models, this design is unique because it works without an electric motor or a generator thereby making it nonelectrical but solely mechanical powered. This design has a height of 10m above the ground and per mathematical calculations can produce 291 W power to drive pumps. The maximum torque in the system was found to be 24.69 Nm.

Traditional Approaches

E-governance is a paradigm shift over the traditional approaches in Public Administration which means rendering of government services and information to the public by using electronic means. In the past decades, service quality and responsiveness of the government towards the citizens were least important but with the approach of E-Government the government activities are now well dealt. This paper withdraws experiences from various studies from different countries and projects facing similar challenges which need to be consigned for the successful implementation of e-governance projects. Developing countries like India face poverty and illiteracy as a major obstacle in any form of development which makes it difficult for its government to provide e-services to its people conveniently and fast. It also suggests few suggestions to cope up with the challenges faced while implementing e-projects in India.

Daily Water

Clean water to poor communities who live in crowded municipal area is stillexpensive and a luxury. This condition is evidenced by the number of people whouse ground water for their daily water, because water taps still seems expensivefor them. Diarrheal disease is still relatively high for Indonesia, where nearly 16thousand people suffer from diarrhea due to poor sanitation. To help the poor inthe city, there are several alternative technologies that can be applied to publicaccess to clean water and adequate low-cost, including ground water treatmenttechnology with a filter system equipped with an ultraviolet sterilizer, or ozonegenerators, or using ultrafiltration, if possible can also use the reverse osmosismembrane that for fresh water. Arsinum is the best alternative should be chosenfor fulfilled potable water in slump area.Keywords : Sanitation, water treatment technology, portable water, low-cost, slump area

Overseas Development

This book, hereinafter referred to as the Guide, has been developed for those social analysts (e.g., anthropologists, sociologists, and human geographers) who have had little or no practical experience in applying their knowledge as development practitioners. In the past, development projects would be analysed from a narrow financial and economic perspective. But with the evolution of thinking on development, this narrow financial and economic aspect has now been broadened to include the impact on society as the very meaning of development has now come to symbolise social change. Thus, development is not restricted only to plans and figures; the human environment in its entirety is now considered for analysis while designing and implementing development projects.

Special Relevance

In the past two decades developing countries have invested an increasing proportion of their resources in new industries and the infrastructure needed to support them. Many of the new industries have been light, simple and con¬sumer-oriented. But a significant number of LDC's, mostly the larger or richer ones, have established heavy, more complex capital-goods industries. Both sectors of industry have been largely domestic-oriented, although there are some LDC's which have succeeded in sharply increasing their industrial exports, mostly of light and simple products. The absence of export success may, in itself, cast a doubt on the effici¬ency and competitiveness of the new industries. The question has been raised in several quarters whether, in fact, the resources spent on industrialization have been well spent or whether the LDC's could have achieved more growth—in domestic product or export earnings—by a different design of industrialization or by more emphasis on other sectors. These questions are of special relevance for the newly-established capital-goods industries, because:

The Relationship

Over the past decade, bilateral relations between China and Russia have attracted the attention of the whole world. As neighbors and rapidly developing countries, China and Russia are becoming increasingly important in the international arena. The strategic partnership and interaction between China and Russia occupy a significant place in the politics of both countries. Cooperation is developing dynamically in various fields, primarily in politics. After 2012, a change of government took place in China and Russia, which brought new changes to international relations. Studying the involvement of the media in this process can clarify their impact on international relations, in particular, their role in the relationship between China and Russia.

Significant Attention

For the past few decades, the mechanisms of immune responses to cancer have been exploited extensively and significant attention has been given into utilizing the therapeutic potential of the immune system. Cancer immunotherapy has been established as a promising innovative treatment for many forms of cancer. Immunotherapy has gained its prominence through various strategies, including cancer vaccines, monoclonal antibodies (mAbs), adoptive T cell cancer therapy, and immune checkpoint therapy. However, the full potential of cancer immunotherapy is yet to be attained. Recent studies have identified the use of bioinformatics tools as a viable option to help transform the treatment paradigm of several tumors by providing a therapeutically efficient method of cataloging, predicting and selecting immunotherapeutic targets, which are known bottlenecks in the application of immunotherapy. Herein, we gave an insightful overview of the types of immunotherapy techniques used currently, their mechanisms of action, and discussed some bioinformatics tools and databases applied in the immunotherapy of cancer. This review also provides some future perspectives in the use of bioinformatics tools for immunotherapy.
