Chemotaxis of Arbacia punctulata spermatozoa to resact, a peptide from the egg jelly layer

Resact, a peptide of known sequence isolated from the jelly layer of Arbacia punctulata eggs, is a potent chemoattractant for A. punctulata spermatozoa. The chemotactic response is concentration dependent, is abolished by pretreatment of the spermatozoa with resact, and shows an absolute requirement for millimolar external calcium. A. punctulata spermatozoa do not respond to speract, a peptide isolated from the jelly layer of Strongylocentrotus purpuratus eggs. This is the first report of animal sperm chemotaxis in response to a defined egg-derived molecule

The swiss army knife of job submission tools: grid-control

Grid-control is a lightweight and highly portable open source submission tool that supports virtually all workflows in high energy physics (HEP). Since 2007 it has been used by a sizeable number of HEP analyses to process tasks that sometimes consist of up 100k jobs. grid-control is built around a powerful plugin and configuration system, that allows users to easily specify all aspects of the desired workflow. Job submission to a wide range of local or remote batch systems or grid middleware is supported. Tasks can be conveniently specified through the parameter space that will be processed, which can consist of any number of variables and data sources with complex dependencies on each other. Dataset information is processed through a configurable pipeline of dataset filters, partition plugins and partition filters. The partition plugins can take the number of files, size of the work units, metadata or combinations thereof into account. All changes to the input datasets or variables are propagated through the processing pipeline and can transparently trigger adjustments to the parameter space and the job submission. While the core functionality is completely experiment independent, integration with the CMS computing environment is provided by a small set of plugins.Comment: 8 pages, 7 figures, Proceedings for the 22nd International Conference on Computing in High Energy and Nuclear Physic

International Perspectives on Parenting Support - Non-English Language Sources

This study was commissioned by the DCSF, and began in October 2007. The project aimed to extend existing knowledge of ‘what works’ in parenting support beyond the English language international evidence that was comprehensively reviewed in an earlier study for DCSF (What Works in Parenting Support, Moran, Ghate and van der Merwe 2004). While the previous study focused on English language literature, the focus of this study was to examine parenting support in a selection of non-English language countries. Five countries were selected from an initial list of 12 (originally chosen from a longer list of 22). Their selection was based on the relevance to UK policy and practice, potential translatability to a UK context and indications of promising practice
