Twin trawling for shrimp with dummy doors

Twin trawling; a new concept in shrimp trawling is described in this paper. It essentially involves towing of two trawls of equal size connected in sequence at the inner head and foot rope legs and using a pair of outer otter boards and central neutral door or dummy door with triple bridles and single tow warp. A comparative study with conventional stern trawling using a standard 13.7 m four seam shrimp trawl and two 6 8 m standard four seam trawls as twin-rig has shown considerable reduction in the utilization of power (20 %) with better efficiency in shrimp fishing.

Hybrid ventilation by revolving doors

The transfers of air driven by a revolving door connecting two rooms of initially different temperatures are investigated. The results of small-scale laboratory modelling show that a critical revolution rate exists for which transfers are maximal for a given combination of door geometry, revolution rate and temperature contrast. This critical revolution rate divides two possible transfer regimes for revolving doors. Potential implications of our findings to revolving door operation, to heat losses across the doorway and to ventilation driven by the door are discussed.

Opening doors as well as banging on tables. An assessment of UNISON/employer partnerships on learning in the UK public sector.

The academic debate on partnerships has so far mainly focused on whether there are mutual gains for both unions and employers and whether they support or undermine branch organisation. This debate is here assessed in relation to learning partnerships, which are considered to be a distinctive form of partnership and represent a process of institution-building.

OPEN DOORS AND OPEN MINDS: WHAT FACULTY AUTHORS CAN DO TO ENSURE OPEN ACCESS TO THEIR WORK THROUGH THEIR INSTITUTION

The Internet has brought unparalleled opportunities for expanding availability of research by bringing down economic and physical barriers to sharing. The digitally networked environment promises to democratize access, carry knowledge beyond traditional research niches, accelerate discovery, encourage new and interdisciplinary approaches to ever more complex research challenges, and enable new computational research strategies. However, despite these opportunities for increasing access to knowledge, the prices of scholarly journals have risen sharply over the past two decades, often forcing libraries to cancel subscriptions. Today even the wealthiest institutions cannot afford to sustain all of the journals needed by their faculties and students. To take advantage of the opportunities created by the Internet and to further their mission of creating, preserving, and disseminating knowledge, many academic institutions are taking steps to capture the benefits of more open research sharing. Colleges and universities have built digital repositories to preserve and distribute faculty scholarly articles and other research outputs. Many individual authors have taken steps to retain the rights they need, under copyright law, to allow their work to be made freely available on the Internet and in their institutionâ s repository. And, faculties at some institutions have adopted resolutions endorsing more open access to scholarly articles. Most recently, on February 12, 2008, the Faculty of Arts and Sciences (FAS) at Harvard University took a landmark step. The faculty voted to adopt a policy requiring that faculty authors send an electronic copy of their scholarly articles to the universityâ s digital repository and that faculty authors automatically grant copyright permission to the university to archive and to distribute these articles unless a faculty member has waived the policy for a particular article. Essentially, the faculty voted to make open access to the results of their published journal articles the default policy for the Faculty of Arts and Sciences of Harvard University. As of March 2008, a proposal is also under consideration in the University of California system by which faculty authors would commit routinely to grant copyright permission to the university to make copies of the facultyâ s scholarly work openly accessible over the Internet. Inspired by the example set by the Harvard faculty, this White Paper is addressed to the faculty and administrators of academic institutions who support equitable access to scholarly research and knowledge, and who believe that the institution can play an important role as steward of the scholarly literature produced by its faculty. This paper discusses both the motivation and the process for establishing a binding institutional policy that automatically grants a copyright license from each faculty member to permit deposit of his or her peer-reviewed scholarly articles in institutional repositories, from which the works become available for others to read and cite.

Making doors open: caring for families of children with severe cerebral palsy

Cerebral palsy is a relatively rare condition affecting approximately 2-2.5 children in every 1,000 (Parkes et al 2001). It is a leading cause of physical disability in childhood and is often associated with severe motor and other impairments (Table 1). Improved survival of small and premature babies who are particularly at risk of developing the condition raises concerns about increasing numbers of children with cerebral palsy possibly with more severe forms. In the UK, information about the number and needs of children with CP is not collected routinely. The most reliable sources of information on CP in the UK comes from five dedicated case registers which have monitored live births in their respective geographically defined areas since the 1960s and 1970s. These registers have formed a collaborative network called the United Kingdom Collaboration of Cerebral Palsy Registers (or UKCP) and are listed in Table 2. All five registers are currently funded and all are active in surveillance activities and research.
