The interaction of private intergenerational transfers types

The rapid ageing of the population, particularly in the developed world, accentuates the importance of both the family and of private intergenerational transfers, whether this be due to the longer periods of coexistence resulting from longer life expectancy or the threat posed to the very sustainability of the welfare state. While the magnitude of intergenerational transfers is well documented, and the motives ...

Notice on a methodology for characterizing emissions of ultrafine particles/nan...

Bearing in mind the potential adverse health effects of ultrafine particles, it is of paramount importance to perform effective monitoring of nanosized particles in several microenvironments, which may include ambient air, indoor air, and also occupational environments. In fact, effective and accurate monitoring is the first step to obtaining a set of data that could be used further on to perform subsequent eva...

Análise das implicações para a saúde humana do uso das nanotecnologias

As nanotecnologias representam um importante potencial para a promoção da qualidade de vida e da competitividade industrial na Europa. Um material com nanodimensões tem uma relação superfície/volume que vai alterar as suas propriedades físicas, químicas, ópticas e magnéticas do material e fazer com que este reaja de maneira diferente e de uma forma desconhecida com os organismos e o ambiente. As nanopartículas ...

Monitorization of alveolar deposited surface area of nanoparticles and ultrafin...

Nanotechnology is an important emerging industry with a projected annual market of around one trillion dollars by 2015. It involves the control of atoms and molecules to create new materials with a variety of useful functions. Although there are advantages on the utilization of these nano-scale materials, questions related with its impact over the environment and human health must be addressed too, so that pote...

Determination of airborne nanoparticles from welding operations

The aim of this study is to assess the levels of airborne ultrafine particles emitted in welding processes (tungsten inert gas [TIG], metal active gas [MAG] of carbon steel, and friction stir welding [FSW] of aluminum) in terms of deposited area in pulmonary alveolar tract using a nanoparticle surface area monitor (NSAM) analyzer. The obtained results showed the dependence of process parameters on emitted ultra...

Lighting conditions at an operating room in a Portuguese maternity

Lighting is one of the most important factors in human interaction with the environment. Poor lighting may increase the risk of accidents and could also cause a variety of symptoms including: rapid fatigue, headaches, eyestrain, tired eyes, dry eyes, ocular surface symptoms (watery and irritated eyes), decreased concentration and stress. Specific disorders: degeneration of the sharpness of vision (blurred and d...

The characteristics and regional distribution of older workers in Portugal

Population ageing is a common trend in most developed countries with many important economic, social and political consequences. In Portugal, this trend has been particularly strong. The ageing index was 34% in 1970, it is about 129% in 2011, according to the provisory results of the last Census and most recent demographic projections, is expected to be over 240% in 2030. One of the main issues associated with ...

Informação ao paciente com câncer: o olhar do oncologista

OBJETIVO: Identificar o que os médicos-oncologistas informam aos seus pacientes, verificar o que levam em consideração no processo de informar, e averiguar a quem fornecem a informação. MÉTODOS: Os sujeitos da pesquisa foram oncologistas, recrutados dentre aqueles inscritos na Sociedade Brasileira de Oncologia Clínica (SBOC). Foi enviado para a sociedade, via correio, todo o material a ser encaminhado aos oncol...

Grandparents and women's participation in the labor market

The conciliation of work and family life is a challenge to most women. In some countries, although not in southern Europe, women make significant use of part-time schedules as a way of balancing work and family life. Informal care, typically care by grandparents, is an alternative. It is cheap, trustworthy, and possibly compatible with non-standard labor schedules. In this paper we investigate how childcare by ...
