Al 88, Si 12 (wt%), eutectic alloy
This sample is a casting alloy of eutectic composition. From the melt a eutectic is formed between aluminium solid solution and virtually pure silicon. Slow solidification produces a very coarse microstructure. The eutectic comprises large plates of silicon in the aluminium matrix. This microstructure displays poor ductility due to the brittleness of large silicon plates. The microstructure is normally refined through either rapid solidification, which lets the silicon phase assume a fibrous for

Delivering Sustainable Development Activity 2: National Strategies
Since 1992 there has seen a significant number of national level initiatives on sustainable development. There has also been a considerable attempt to identify and reflect on those elements within national strategies which represent 'good practice'. Whilst national conditions, circumstances and priorities may be vary sharply, there is growing consensus that a set of key principles represent the foundation upon which to build specific national sustainable agendas.

The remote experiment position in actual taxonomy
Taxonomy is a classification effort for establishment of learning/teaching operational objectives. There are some famous taxonomies, Bloom’s being the most quoted. In spite of the fact that some researchers have tried to explain the position of elearning in already known taxonomies, this subject was not too much in the general attention. In the paper the authors intend to go deeply and to analyze the position of the new methodology-remote experiment-in the actual taxonomies. In addition they ha

Distributing the downturn
The International Labour Organisation has forecast a rise in unemployment by 20 million world-wide, by the end of 2009. The Organisation for Economic Co-operation and Development (OECD) has forecast a loss of up to 10 million jobs within the OECD group of countries, and up to 25 million jobs world-wide between 2008 and 2010. However, would a strategy of cutting wages as opposed to cutting jobs in the face of this recession create the conditions for economic recovery? Dr Paul Kattuman believes it

Structural analysis of the evolution of steroid specificity in the mineralocorticoid and glucocortic
Background The glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) evolved from a common ancestor. Still not completely understood is how specificity for glucocorticoids (e.g. cortisol) and mineralocorticoids (e.g. aldosterone) evolved in these receptors. Results Our analysis of several vertebrate GRs and MRs in the context of 3D structures of human GR and MR indicates that with the exception of skate GR, a cartilaginous fish, there is a deletion in all GRs, at the position corresp

Wiggle -- Predicting Functionally Flexible Regions from Primary Sequence
The Wiggle series are support vector machine-based predictors that identify regions of functional flexibility using only protein sequence information. Functionally flexible regions are defined as regions that can adopt different conformational states and are assumed to be necessary for bioactivity. Many advances have been made in understanding the relationship between protein sequence and structure. This work contributes to those efforts by making strides to understand the relationship between p

"No Other Work Available for Me and My People": A Comanche Indian Migrant Farmworker Testifies befor
In the early 20th century, large-scale commercial agriculture displaced family farms, tenant farmers, and sharecroppers. Hand labor, however, remained more cost effective for harvesting certain fruits and vegetables. Farmworkers under this new system were hired only for seasonal work and had to travel frequently. The migratory experience left these workers--primarily Mexicans, Mexican Americans, African Americans, Puerto Ricans, and Filipinos÷permanent outsiders and vulnerable to exploitation,
