Experimental investigation of phase equilibria in the ZrCu-Al system at 500º C

Weight is of a fundamental importance in the performance of aircraft. Finding new materials for the structural elements of an aircraft that are lighter while giving the performance needed is crucial. Al alloys are commonly utilized materials because of their relatively low density and good mechanical properties. This is why the Zr-Cu-Al ternary system has been chosen in this study. There is no agreement on the shape of the isothermal phase diagram of this system. This study has the goal of adding some light on this matter, by finding yet another result that can help us understand better this system. In this study the isothermal section of the Zr-Cu-Al system at 500 ºC is experimentally determined

The economic costs of alcohol misuse in Portugal

Aim: This study estimates the total economic burden of alcohol misuse in Portugal. Specifically, it reports estimates of morbidity and co-morbidity treatment costs and assesses the value of lost productivity related to alcohol misuse, for the year 1995. Methods and Sources: The study examines health care costs focusing on the nine most frequent diseases associated with alcohol misuse. The societal perspective was adopted and the prevalence-based Cost-of-Illness studies used to evaluate annual costs. The study is based on data obtained from different appropriate sources. Medical records from 88 public short-stay hospitals, provided by the Financing Management Institute in the Portuguese Ministry of Health. Hospital discharges, death causes and consultations obtained from Health Statistics and Mortality Statistics, published by the National Statistical Institute. And data on crime and motor vehicle crashes reported in the Sixth United Nations Survey on Crime Trends (UNICRI) and in the General State Account, published by the Ministry of Finance. Results : Approximately 19 878 discharges from alcohol misuse, representing 2.3% of total discharges, were estimated to occur in public short-stay hospitals. In public and private psychiatric hospitals 2 613 alcoholic discharges were estimated (18% of total mental health discharges in that year). The annual costs of health care services amounted to €33 million. Of this, 63% was due to inpatient care and 24% to ambulatory care. The criminal justice system and prison administration were estimated to cost €19 million whilst property damages due to motor vehicle crashes amounted to €57 million. Indirect costs were estimated to be €325 million. Of this, €76 million was due to the human cost of premature mortality. Conclusions : It is concluded that, in 1995, alcohol misuse imposed a burden of €434 million on the Portuguese economy, representing 0.6 % of Gross Domestic Product and a per capita cost estimate of €52. In examining the share of each component in total costs, both criminal justice and hospital care systems appear to have similar burdens, imposed by alcohol misuse. However, the greatest burden arises from losses in productivity resulting from illness and premature death.Fundação para a Ciência e a Tecnologia (FCT

Recomendações para a geração de composições de máximo valor a partir de imagens AVHRR/NOAA.

As imagens de satélite são uma fonte importante de informações sobre a superfície terrestre, pois sua visão sinóptica, temporal e multiespectral auxilia no entendimento dos processos que ocorrem nos ecossistemas terrestres. Ao longo dos anos, as pesquisas envolvendo o sensoriamento remoto na agricultura têm explorado a alta frequência de revisita de alguns sensores orbitais, como o Advanced Very High Resolution Radiometer (AVHRR), o Moderate Resolution Imaging Spectroradiometer (Modis) e o Vegetation, que fornecem imagens multiespectrais diárias da superfície terrestre, a partir das quais podem ser derivados produtos como índices de vegetação, temperatura de superfície, albedo de superfície, entre outros.bitstream/item/55904/1/ComTec107.pd

The Transit Light Curve project. XIV. Confirmation of Anomalous Radii for the Exoplanets TrES-4b, HAT-P-3b, and WASP-12b

We present transit photometry of three exoplanets, TrES-4b, HAT-P-3b, and WASP-12b, allowing for refined estimates of the systems' parameters. TrES-4b and WASP-12b were confirmed to be "bloated" planets, with radii of 1.706 +/- 0.056 R_Jup and 1.736 +/- 0.092 R_Jup, respectively. These planets are too large to be explained with standard models of gas giant planets. In contrast, HAT-P-3b has a radius of 0.827 +/- 0.055 R_Jup, smaller than a pure hydrogen-helium planet and indicative of a highly metal-enriched composition. Analyses of the transit timings revealed no significant departures from strict periodicity. For TrES-4, our relatively recent observations allow for improvement in the orbital ephemerides, which is useful for planning future observations.Comment: AJ, in press [11 pages]; corrected error in distance to WASP-1
