Creep studies on oriented thermoplastics

The enhancement of many of the mechanical properties of thermoplastics which may be achieved by orienting the molecules has been known for some time. It has been exploited in the production of textile fibres end oriented films. Molecular orientation also occurs during processes such as extrusion, moulding or forming. Here, unless carefully controlled, it may well cause a deterioration in the properties of the finished article. In view of this a systematic study on the anisotropy of the mechanical properties of thermoplastics, resulting from molecular orientation, is being carried out at present in these laboratories … [cont.]

An apparatus for the measurement of tensile creep and contraction ratios in small non-rigid specimens

An apparatus is described for precise measurement of creep properties in specimens with gauge lengths down to 1.2 cm. An extensometer has been developed which is supported independently of the specimen and exerts a load on the specimen of less than 5 grams. It can thus be used with small non-rigid specimens. The extensometer will detect strains down to 2 x 10-6. The stability is excellent. An adaptation of the system which allows simultaneous measurement of tensile strain and lateral strain during creep is also described. The apparatus was designed for the measurement of anisotropy of creep properties in oriented thermoplastics and reference to such measurements is given. It is however entirely suitable for general application to small specimens

Running a Production Grid Site at the London e-Science Centre

This paper describes how the London e-Science Centre cluster MARS, a production 400+ Opteron CPU cluster, was integrated into the production Large Hadron Collider Compute Grid. It describes the practical issues that we encountered when deploying and maintaining this system, and details the techniques that were applied to resolve them. Finally, we provide a set of recommendations based on our experiences for grid software development in general that we believe would make the technology more accessible. © 2006 IEEE

Exploring ethnic inequalities in health: Evidence from the Health Survey for England, 1998-2011

Issues of social justice and social and spatial inequalities in health have long been researched, yet there is a relative paucity of research on ethnic inequalities in health. Given the increasing ethnic diversity of England's population and the persistence of unjust differences in health this research is timely. We used annual data from the Health Survey for England between 1998 and 2011, combined into a time-series dataset, to examine the influence of socioeconomic and spatial factors on ethnic variations in health and to explore whether inequalities have changed over time. Our analysis reveals that ethnic differences in health are largely rooted in socioeconomic or spatial difference, although variations by health outcome are observed. This work builds on existing literature which looks to socioeconomic and spatial difference for explanations of ethnic inequalities in health, rather than any supposed inherent underlying risk of poor health for minority ethnic groups

Radical political unionism reassessed

Defections from European social-democratic parties and a resurgence of union militancy have prompted some to diagnose a new left-wing trade unionism across Europe. This comment on the article by Connolly and Darlington scrutinizes trends in France and Germany but primarily analyses recent developments in Britain. While there are some instances of disaffiliation from the Labour Party, support for electoral alternatives, growth in political militancy and emphasis on new forms of internationalism, these have been limited. There is insufficient evidence to suggest that we are witnessing the making of a new radical collectivism

Poverty dynamics and livelihood challenges among small-scale fishing communities on lake Kariba - Zimbabwe

Magister Philosophiae - MPhilPoverty dynamics and livelihood challenges among small-scale fishing communities on Lake Kariba (Zimbabwe) The aim of this study was to assess poverty among small-scale fishing communities on Lake Kariba (Zimbabwe) as well to as identify livelihood challenges that confront them. Two fishing communities were used as case studies and were uniquely selected from among the many fishing camps/villages dotted along the Zimbabwean shoreline of Lake Kariba. Depending on gear type, fishing activities on Lake Kariba target both the smaller-sized Kapenta species and larger species such as the bream and the tiger. Fishing activities are a major livelihood source for fishers in the two case studies upon which they obtain food and derive income to address other family needs. Mutual linkages and exchanges also exist between fishing camps/villages and communal areas where land-based activities such as cropping and livestock rearing are carried out. Before fieldwork, there was a pre-conceived notion that members of fishing communities on Lake Kariba were very poor. Although the fishers expressed desires for a better life than they were experiencing, they did not consider themselves poor. Instead, they rated their economic position as well off compared to some of their urban counterparts. However, on further interrogation, the study revealed that the fishers were facing a set of vulnerabilities that is commonly associated with the fishing profession. These vulnerabilities had substantial impacts on the livelihood system of these fishers. Using vulnerability ladders, a picture was painted depicting the severity of these vulnerabilities. It emerged that fishers were more vulnerable to existing state institutions that are designed to manage access to and the use of natural resources in the country. There are several reasons to suggest why this is the case which include, (i) the high cost of accessing the fishery, (ii) the stern measures in place that restrict access to and use of the fishery, and (iii) the punitive measures imposed for contravening rules of access and use of the fishery. Although restricting access is in line with the principle of long run sustainability of the fishery, it may threaten the development of the fishing industry and impact negatively on livelihoods of communities involved. Unlike fisheries elsewhere in the world, Lake Kariba is not viewed as a vehicle for reducing poverty and achieving food security. On the contrary, government places emphasis on preserving and enhancing the natural environment both aquatic and non-aquatic with a view to sustaining tourism. Under such a paradigm, fishing is viewed as a threat to the natural environment and requires strict management. Heavy fines are therefore imposed on users that violate the rules of access. Many of the fishers have had their properties attached after failing to raise the necessary amounts to cover the fines. By shifting away from the promotion of fisheries, government has accelerated the decline of the small-scale fishing industry on Lake Kariba, through narrowing the fishers action space and creating an environment conducive for corruption. The decline has subsequently shrunk the livelihoods base of local communities as well as many others who are associated with the fishing industry. While the sustainability of the fishery is paramount, government needs to reconsider its strategy on governing and managing fisheries on Lake Kariba. Given enough support, small-scale fisheries on Lake Kariba have the potential to contribute significantly to the country’s Gross Domestic Product. Small-scale fisheries have also proved their resilience in the wake of the severe economic crisis that Zimbabwe experienced between 2007 and 2009. During this period, there were widespread shortages of basic food items in the country and the demand for fish and fish products rose drastically. The fishers reported that there was an increase in the demand for fish during the crisis period to the extent that they could not supply enough to satisfy the market. This supports the observation by the United Nations (2010) that fisheries, in particular small-scale, can play an important role in the economy in terms of livelihoods, poverty reduction and food security. Fishing activities are also the perfect complement to other land-based livelihood activities for communities that live in close proximity to large water bodies
