Control of E. coli and Salmonella in growing-finishing pigs through the use of potassium diformate (KDF) – European case studies

Control of pathogenic bacteria has a high priority in European pork production. They can be a significant cause of zoonotic diseases and cause major economic losses in the pork production chain, through reduced productivity, increased veterinary and hygiene control costs. Preventing the spread of E. coli and Salmonella to the consumer requires special control measures during slaughter and processing. The extra cost of these controls is increasingly being transferred back to the producer in the form of financial penalties or the loss of the market for contaminated pigs. Improving gut health has been shown to be effective against intestinal pathogens, a strategy that has only really been made possible through the removal of antibiotic growth promoters in feed. Creating and maintaining a healthy intestinal environment has become essential to productivity and food safety programmes alike

On a Coccidium (\u3ci\u3eKlossiella muris\u3c/i\u3e, gen. et spec. nov.) Parasitic in the Renal Epithelium of the Mouse

In 1889, Smith published a preliminary description of a polysporous coccidium found in the epithelium of the convoluted tubules of the mouse\u27s kidney. Several stages of the parasite were seen but the scantiness of the material left many gaps in the life-cycle. During investigations recently made to determine the mode of transmission of the Sarcosporidium of the mouse, Smith found a considerable number of gray mice, caught in the animal room connected with this laboratory, whose kidneys were abundantly invaded by this coccidium. This favorable opportunity of examining more thoroughly into the life-history of this sporozoon was utilized, and, as a result, we are able to add materially to the knowledge of this cell parasite. In the following pages some details given in the first paper will be repeated to avoid obscurity in the descriptions as well as to aid those to whom the first paper is inaccessible. Thus far we have found only adult mice infected. The invaded kidneys are a trifle enlarged and the surface is faintly uneven. The most characteristic feature is a very delicate mottling of the whole surface with minute, barely visible, grayish specks. This appearance of the kidneys may be considered almost diagnostic of the presence of the parasite

Urban wind power and the private sector : community benefits, social acceptance and public engagement

Given the ambitious government targets for renewable energy generation in the UK, there has been a push by government and industry towards various types and scales of Renewable Energy Technologies (RETs). This paper explores the implications of commercial urban wind projects for local communities, drawing on a case study of proposals by ASDA to construct wind turbines in two semi-urban locations in the UK. The paper argues that community responses to the proposals were complex and varied and could not adequately be encapsulated by 'nimby' (not in my back yard) assignations. It concludes that while ASDA followed a process of consulting local people, this process highlighted the problems of the 'business as usual' approach to public engagement employed by ASDA, and assumptions made about public acceptance of RETs

The Nonlinear Debye-Onsager Relaxation Effect in Weakly Ionized Plasmas

A weakly ionized plasma under the influence of a strong electric field is considered. Supposing a local Maxwellian distribution for the electron momenta the plasma is described by hydrodynamic equations for the pair distribution functions. These equations are solved and the relaxation field is calculated for an arbitrary field strength. It is found that the relaxation effect becomes lower with increasing strength of the electrical field.Comment: 4 pages, 1 figur

Trio-One: Layering Uncertainty and Lineage on a Conventional DBMS

Trio is a new kind of database system that supports data, uncertainty, and lineage in a fully integrated manner. The first Trio prototype, dubbed Trio-One, is built on top of a conventional DBMS using data and query translation techniques together with a small number of stored procedures. This paper describes Trio-One's translation scheme and system architecture, showing how it efficiently and easily supports the Trio data model and query language
