A new concept of Phase Change Materials (PCM) device has recently been developed to improve the thermal control of spacecraft. Two Phase Change Material candidates have been selected after extensive testing of a set of available materials. Special attention has been paid to the hysteresis and ageing. In the design of the container, the thermal expansion of the PCM is a critical parameter that has been taken into consideration by two competing technologies. These designs have been tested: a prototype of PCM heat storage device has been effectively manufactured and tested under vacuum environment. 1D and 2D mathematical models have been developed. Conclusions are drawn to promote the use of PCM Heat Storage device in various space missions. [less ▲]

The arginine vasopressin (AVP) gene is expressed in certain cancers such as breast cancer, where it is believed to act as an autocrine growth factor. However, little is known about the regulation of the AVP protein precursor (proAVP) or AVP-mediated signaling in breast cancer and this study was undertaken to address some of the basic issues. The cultured cell lines examined (Mcf7, Skbr3, BT474, ZR75, Mcf10a) and human breast cancer tissue extract were found to express proAVP mRNA. Western analysis revealed multiple forms of proAVP protein were present in cell lysates, corresponding to those detected in human hypothalamus extracts. Monoclonal antibodies directed against different regions of proAVP bound to intact live Mcf7 and Skbr3 cells. Dexamethasone increased the amount of proAVP-associated glycopeptide (VAG) secreted by Skbr3 cells and a combination of dexamethasone, IBMX and 8br-cAMP increased cellular levels of VAG. Exogenous AVP (1, 10, and 100 nM) elevated phospho-ERK1/2 levels, and increased cell proliferation was observed in the presence of 10 nM AVP. Concurrent treatment with the V1a receptor antagonist SR49059 reduced the effects of AVP on proliferation in Mcf7 cells, and abolished it in Skbr3 cells. Results here show that proAVP components are found at the surface of Skbr3 and Mcf7 cells and are also secreted from these cells. In addition, they show that AVP promotes cancer cell growth, apparently through a V1-type receptor-mediated pathway and subsequent ERK1/2 activation. Thus, strategies for targeting proAVP should be examined for their effectiveness in diagnosing and treating breast cancer. [less ▲]

BACKGROUND: International comparisons of health care systems have shown a relationship at the macro level between a well-structured primary health care plan and lower total health care costs. The objective of this study was to assess whether provider continuity with a family physician is related to lower health care costs using the individual patient as the unit of analysis. METHODS: We undertook a study of a stratified sample of patients (age, sex, region, insurance company) for which 2 cohorts were constructed based on the patients' utilization pattern of family medicine (provider continuity or not). Patient utilization patterns were observed for 2 years. The setting was the Belgian health care system. The participants were 4,134 members of the 2 largest health insurance companies in 2 regions (Aalst and Liege). The main outcome measures were the total health care costs of patients with and without provider continuity with a family physician, controlling for variables known to influence health care utilization (need factors, predisposing factors, enabling factors). RESULTS: Bivariate analyses showed that patients who were visiting the same family physician had a lower total cost for medical care. A multivariate linear regression showed that provider continuity with a family physician was one of the most important explanatory variables related to the total health care cost. CONCLUSIONS: Provider continuity with a family physician is related to lower total health care costs. This finding brings evidence to the debate on the importance of structured primary health care (with high continuity for family practice) for a cost-effective health policy. [less ▲]

This article presents a new stability prediction tool. The method is based on the dynamic behaviour of both milling tool and workpiece, computed using finite element method. Dynamic behaviour is expressed under the form of transfer functions and used to predict stability lobes at each tool position. The unconditionally stable depth of cut is then stored and displayed on a graphic representation of the machined surface under the form of colour axis, named stability map. An application of the method on a Renault cylinder block is presented as an illustration. (C) 2006 Elsevier Ltd. All rights reserved. [less ▲]

Long-term care (LTC hereafter) concerns people who depend on help to carry out daily activities. It is mainly delivered informally by families and to a lesser extent formally by professional care assistants and nursing homes. Most EU governments are also involved in some way in the provision or financing of LTC services. Right now, the future of LTC provision appears to be gloomy, for demographic, societal and financial reasons. This TSE Note studies the strengths and weaknesses of three institutions providing LTC services - namely the family, the State and the private insurance market - and provides policy recommendations based on the view that governments should take the leadership towards a comprehensive approach of the dependency problem, while relying as much as possible on the family and the market.

The authors report their experience with operative treatment of 18 proximal fifth metatarsal stress fracture in 17 soccer players. Percutaneous intramedullary fixation with a 4.5 mm malleolar screw was used in 11 patients (group 1) and open intramedullary screw fixation associated with autologous cancellous bone grafting in 7 other (group 2). The average follow-up was 3.1 years. Clinical and radiographic union was obtained in all cases. The average return to full sports practice was 12 weeks. Refracture occurred in three players in the first group at 4.5, 5.2 and 6.0 months after return to full sport activity. They underwent reoperation with screw exchange, curettage of the fracture site and autologous cancellous bone grafting. No case of refracture was reported in the second group. On the basis of this series, intramedullary screw fixation associated with autologous cancellous bone grafting seems to be a reasonable primary treatment in high level soccer players. [less ▲]
