Environmental policies in an international mixed duopoly

The purpose of this paper is to study the effects of environmental and trade policies in an international mixed duopoly serving two markets. We suppose that the firm in the home country is a welfare-maximizing public firm, while the firm in the foreign country is its own profit-maximizing private firm. We find that the environmental tax can be a strategic instrument for the home government to distribute production from the foreign private firm to the home public firm. An additional effect of the home environmental tax is the reduction of the foreign private firm's output for local consumption, thereby expanding the foreign market for the home public firm.

Protection of interconnected wind turbines against lightning effects: overvoltages and electromagnetic transientes study

This paper is concerned with direct or indirect lightning strokes on wind turbines, studying overvoltages and electromagnetic transients. As wind power generation undergoes rapid growth, lightning damages involving wind turbines have come to be regarded with more attention. With the aim of providing further insights into the lightning protection of wind turbines, describing the transient behavior in an accurate way, the restructured version (RV) of the electromagnetic transients program (EMTP) is used in this paper. A new case study is presented with two interconnected wind turbines, considering a direct lightning stroke to the blade or considering that lightning strikes the soil near a tower. Comprehensive computer simulations with EMTP-RV are presented and conclusions are duly drawn.

Acute Hepatitis B in a patient previously positive for antibody to surface antigen (anti-HBs) determined by radioimmunoassay: case report and review of the literature

The determination of anti-HBs as a screening test before vaccination has been advisable in order to encounter immune individuals that don't need to receive vaccine protection. A case-report is presented and three other cases are reviewed from the literature. Anti-HBs was positive in these health-care personnels that developped typical acute B hepatitis. Different subtyping involving the d/y determinants were found in the first case, but false-positive anti-HBs even with high titres, determined by RIA, were found in the other cases. Concomitant determination of anti-HBc or absence of screening tests seem to be more reasonable policies until a low-cost and risk-free vaccine is produced.

Protection of athymic (Nu/Nu) BALB/c mice against Plasmodium berghei by splenocytes from normal (Nu/ +) BALB/c mice

Athymic BALB/c (Nu/Nu) mice died at 7-13 days after inoculation (DAI) of Plasmodium berghei NK65, whereas their heterozygous (Nu/+) littermates died at 7-8 DAI. Nude (Nu/Nu) mice, reconstituted with 2 x 10(7) splenocytes from uninfected heterozygous (Nu/+) littermates at 20 days before parasite inoculation (DBI), died about 2 days earlier than control nude mice; nude mice reconstituted at 10 or 2 DBI lived 2 to 4 days longer than control nudes; and nude mice reconstituted 2 DAI lived even longer and some survived. These findings indicate that P. berghei NK65 induces at least two T-cell dependent immune phenomena, one suppressive and the other stimulatory. Reconstitution of nude mice with T-cells from BALB/c (Nu/+) mice appeared to reduce or bypass suppressive T-cell activities which allowed the formation of a protective immune response by some of the nude mice.

Programas de intervenção municipal orientados para a promoção do envelhecimento activo

RESUMO: O novo cenário demográfico origina mudanças na estrutura etária, nas relações familiares e de trabalho, nas exigências de cuidados de saúde e de protecção social. Estas constituem fortes desafios a enfrentar pelas políticas públicas, exigindo a preparação dos organismos responsáveis. O “envelhecimento activo” começa a ter lugar como paradigma de intervenção, representando já um marco político mundial, na medida em que pode contrariar ou inverter as tendências nefastas das novas transformações. A investigação incidiu numa reflexão em torno das políticas que procuram responder à intensificação e diversidade dos problemas inerentes ao envelhecimento populacional. Envolvemo-nos numa tarefa de análise detalhada de programas municipais em três concelhos da Região Interior de Portugal, segundo a perspectiva e os determinantes do “envelhecimento activo”. Embora não exista uma solução única e definitiva, se nos detivermos no conceito como estratégia global, conclui-se o dever de considerar diversos determinantes numa perspectiva integrada e individualizada, que percorra todo o curso de vida. Os programas devem procurar enfatizar estilos de vida saudáveis com vista num alcance da maior qualidade de vida possível e ter em conta as situações sócio-económicas, mas sem se afastarem do dever de reforçar a componente reparadora e inclusiva da velhice.-----------ABSTRACT: The new demographic scenario creates changes in the age structure, in the family and work relations, in healthcare and social protection demands. All these changes create a great challenge to public policies, demanding the preparation of the responsible organizations. The “active ageing” starts to be seen as the intervention model, which represents a milestone in global policies as it can counteract or reverse the negative trends of these demographic changes. This research focused on the policies that seek to respond to the intensity and diversity of the population aging problems in Portugal. It was produced a detailed analysis of three local programs following the mainstreaming of “active ageing” in interior country. Although there is no unique and definitive solution, if we take the concept as a global strategy, then we can conclude the obligation to consider several determinants in an integrated and individualized perspective, which covers the entire course of life. These programs should emphasize healthy lifestyles aiming the highest quality of life possible taking into account the socioeconomic situations, without disregarding the duty of reinforce the repairing and inclusive component of ageing.

Protection of C57BL/10 mice by vaccination with association of purified proteins from Leishmania (Leishmania) amazonensis

In the past few years, induction of protective immunity to cutaneous leishmaniasis has been attempted by many researchers using a variety of antigenic preparations, such as living promastigotes or promastigote extracts, partially purified, or defined proteins. In this study, eleven proteins from Leishmania (Leishmania) amazonensis (LLa) with estimated molecular mass ranging from 97 to 13.5kDa were isolated by polyacrylamide gel electrophoresis and electro-elution. The proteins were associated as vaccine in different preparations with gp63 and BCG (Bacilli Calmette-Guérin). The antigenicity of these vaccines was measured by their ability to induce the production of IFN-g by lymphocyte from subjects vaccinated with Leishvacinâ . The immunogenicity was evaluated in vaccinated mice. C57BL/10 mice were vaccinated with three doses of each vaccine consisting of 30 mg of each protein at 15 days interval. One hundred mg of live BCG was only used in the first dose. Seven days after the last dose, they received a first challenge infection with 105 infective promastigotes and four months later, a second challenge was done. Two months after the second challenge, 42.86% of protection was obtained in the group of mice vaccinated with association of proteins of gp63+46+22kDa, gp63+13.5+25+42kDa, gp63+46+42kDa, gp63+66kDa, and gp63+97kDa; 57.14% of protection was demonstrated with gp63+46+97+13.5kDa, gp63+46+97kDa, gp63+46+33kDa, and 71.43% protection for gp63 plus all proteins. The vaccine of gp63+46+40kDa that did not protect the mice, despite the good specific stimulation of lymphocytes (LSI = 7.60) and 10.77UI/ml of IFN-g production. When crude extract of L. (L.) amazonensis was used with BCG a 57.14% of protection was found after the first challenge and 28.57% after the second, the same result was observed for gp63. The data obtained with the vaccines can suggest that the future vaccine probably have to contain, except the 40kDa, a cocktail of proteins that would protect mice against cutaneous leishmaniasis.

Salud y Seguridad del Trabajo en Portugal : apuntes diversos

RESUMO - El autor aborda algunos aspectos relativos a la Salud y Seguridad del Trabajo (SST) en Portugal llamando la atención para, esencialmente, intentar sostener la tesis de que, desde mediados de la década de los 90, se observaron importantes avances en la mejoría de las condiciones del trabajo en la perspectiva de la SST, aunque se mantuvieron algunos problemas en la práctica concreta de las normativas legales. Incluso con estas mejoras, las tasas de frecuencia de accidentes de trabajo y de enfermedades profesionales en Portugal todavía se mantienen muy elevadas necesitando, por tanto, estrategias más “agresivas” para concienciar la sociedad portuguesa en torno a las políticas públicas de SST efectivamente promotoras de prevención de riesgos profesionales y de la promoción de la salud de quien trabaja. Es por tanto indispensable que la protección de la salud y de la seguridad de los trabajadores en los puestos de trabajo sea encarada como un conjunto de actividades de indiscutible utilidad para todos los representantes del mundo del trabajo e que la agenda política pase a valorizar, aún más, la promoción de espacios de trabajo saludables y seguros, con la consecuente valorización de las variables individuales en la estrategia nacional de salud y seguridad.--------------------------ABSTRACT – In the present work, the author analyzes several aspects of Occupational Health and Safety (OHS) in Portugal. He provides evidence sustaining the assumption of an important progress, since the mid-nineties, in the improvement of the working conditions from an OHS perspective. Nevertheless, several problems still remain in the practical application of legal regulations. In addition, despite of these improvements, the frequency rates of working accidents and occupational diseases remain very high. Hence, more “aggressive” strategies are required to increase the awareness of the Portuguese society relative to the OHS public policies, whose effectiveness has been demonstrated either in terms of occupational risks prevention and workers health promotion. The protection of workers’ health and safety at the workplace must then be assumed as an activity of indisputable utility by all stakeholders. The political agenda must thus promote even more the promotion of healthy and safe workplaces. As a consequence, there would be also a higher development of individual aspects, and not only environmental data, in the national strategy of occ
