The paper deals with the development of a tool used for the life cycle assessment of residential buildings located in three different European towns: Brussels (Belgium), Coimbra (Portugal) and Luleå (Sweden). The basic tool focuses on the structure and the materials of the buildings and permits the evaluation of the Embodied energy, Embodied carbon and yearly energy consumption. For that purpose, a different set of original data is taken into account for each location, in which the monthly temperatures, energy mix, heating and cooling systems are defined. The energy consumption, being for heating space or water, for cooling or for lighting is transformed into CO2 emissions to deduce the Operational carbon as well. The influence of the energy mix can therefore be assessed in the basic tool. As a matter of fact, the heating and cooling systems habitually used in the three countries are also of great importance. The District Heating system, is, for instance, incorporated in the basic tool. The presence of solar water heater or photovoltaic panels is also strongly influencing the operational carbon. After a short literature review on building LCA and the description of the basic tool, the software Pleiades+Comfie combined with Equer is used to achieve the complete LCA for one building using two different load bearing frames. The results of the calculations for Brussels climate are verified against these software results. The dependence of the results to parameters such as climate, energy mix and habits is then discussed in the companion paper. [less ▲]

The paper presents the comparative results of the life-cycle assessment (LCA) of one residential building with two constructive systems in Brussels and one steel frame house located in three different European towns: Brussels (Belgium), Coimbra (Portugal) and Luleå (Sweden). In a recent study, a modular building was studied in Coimbra and Luleå. It was shown that in terms of CO2 emissions, the Use Stage was the most harmful stage during the building life-cycle for Coimbra climate. Contrarily, in Luleå, it was the Product Stage, despite energy consumption being higher than Coimbra, due to the way electricity and heat are generated. In the present study, two structural systems are first compared for the Belgian house: steel frame and traditional masonry. A different life-cycle scenario is taken into account for the steel frame house for the three different locations, in which the monthly temperatures, energy mix, heating and cooling systems are defined. The LCA is carried out using the basic tool described in the companion paper. It is worth recalling that the results obtained with the basic tool were verified against Pleiades+Comfie and Equer software, enabling to carry out a complete LCA, for Brussels. Our results confirm that for all the three climates, the Use Stage (Operational energy) is the most harmful period during the building life-cycle and that the energy mix of the country strongly influences the equivalent CO2 emissions related to the Use Stage (Operational carbon) and may entirely reverse the conclusions about the life-cycle carbon footprint of the building.

This paper presents a comparative study showing the environmental profile of structural members used in the construction domain. The functional unit is a column that is realistic in terms of dimensions and load bearing capacity, made of steel or high strength steel sections, steel and concrete (composite), reinforced concrete, solid wood and glue-laminated wood. The design of the columns is made following the Eurocodes. Several environmental impacts are assessed, such as the global warming potential and energy consumption while also focusing on the acidification potential. The results are presented in the forms of bar charts for each considered column. For steel and concrete, depending on the source of information, the inven-tory can vary substantially e.g. the CO and CH4 emissions. Several sources of information are provided and used to perform a brief sensitivity analysis. The influence of the recycling of steel taking into account the IISI methodology will also be discussed.

In this paper we introduce a linear bequest motive into a standard life-cycle model, both allowing for credit and annuity market imperfections. First, we characterize the consumption and wealth processes.We find that consumption is non-increasing in the linear bequest parameter for the simplest certainty case, but that the same is not true for life-span uncertainty. Second, we study the issue of annuity valuation. For a sufficiently strong bequest motive, the true value of an annuity is equal to the actuarial value. This invalidates a previous claim that, for imperfect annuity markets, it is close to the simple financial value. [less ▲]

Several factors, including fruit and vegetables intakes, have been shown to significantly influence the plasma concentrations of the two antioxidants vitamin C and β-carotene. Deficiency levels of 6 mg/L (34.2 μM) for vitamin C and of 0.22 mg/L (0.4 μM) for β-carotene have been suggested below which cardiovascular risk might be increased. The present study performed on 897 presumably healthy subjects aged 40–60 years aimed to examine how modifiable lifestyle factors may be related to vitamin C and/or β-carotene deficiency. Gender, smoking, lack of regular physical activity and of daily fruit consumption (≥2/day), and social status (in particular, unemployment) were found to be significant risk factors for vitamin C deficiency. For β-carotene deficiency, the same factors were identified except social status; moreover, overweight and OC use in women were also found to have a deleterious effect. For non exposed subjects, the probability of developing vitamin C deficiency was 4% in men and 2.4% in women. This probability increased to 66.3% for men and to 44.3% for women (and even to 50.4% under OC use), when all risk factors were present. For β-carotene deficiency, the corresponding probabilities were equal to 29.7% in men and 13.7% in women (no risk factor present), and to 86.1% for men and 69.9% (91.6% for OC use) for women (all factors present), respectively [less ▲]

OBJECTIVE: To evaluate the association between lifestyle and dietary factors and serum concentrations of androgens in middle-aged healthy men. METHODS: We conducted a cross-sectional analysis of the association of lifestyle factors with circulating concentrations of androstenedione (A-dione), 3-alpha-androstanediol glucuronide (A-diol-g), testosterone (T), SHBG (sex hormone-binding globulin), and free testosterone (FT) among 636 men in the European Prospective Investigation into Cancer and Nutrition. RESULTS: Compared with the youngest age group (40-49 years), the oldest (70-79 years) had a higher mean concentration of SHBG (by 44%) and lower mean concentrations of A-diol-g (by 29%) FT (19%). Men in the highest BMI group (> or =29.83 kg/m(2)) had a higher mean A-diol-g concentration (by 38%) and lower mean concentration of T (by 20%) SHBG (29%) compared with the lowest (<24.16 kg/m(2)). Current smokers had higher mean concentrations of T (by 13%), SHBG (14%), and A-dione (15%) compared with never smokers. Physical activity and dietary factors were not associated with androgen concentrations, although men in the highest fifth of alcohol intake had higher mean concentrations of A-dione (by 9%), FT (11%) compared with the lowest. CONCLUSION: Our results suggest that age, body weight, smoking, and alcohol intake are associated with circulating androgen concentrations in men. [less ▲]

OBJECTIVES: To estimate the lifetime absolute risks of hip and other osteoporotic fracture in Belgian women aged 60 years and to examine the effect of changes in baseline population fracture risk and changes in life expectancy. MATERIALS AND METHODS: Estimates were performed using a Markov microsimulation model and were based on the incidence of first fracture as well as life expectancy. Baseline scenario included projected mortality rates and increasing fracture incidence by 1% per year. Alternative scenarios were performed on age, life expectancy and trends in fracture incidence. Lifetime fracture risk for osteoporotic population (T-score <or= -2.5) was also estimated. RESULTS: In the baseline scenario, lifetime absolute risks of hip fracture and of any major osteoporotic fracture (hip, clinical vertebral or wrist) were respectively 24.8% and 44.3%. Alternative scenarios showed that when assuming no change of age-specific fracture rates over time, these lifetime risks were 18.3% and 35.2%, while these values were 20.0% and 38.3% assuming no future mortality reductions. For osteoporotic women, these values were respectively 34.5% and 51.5%. CONCLUSION: We conclude that absolute lifetime fracture risks are substantial and that trends in fracture incidence and changes in life expectancy have a marked impact on absolute lifetime fracture risks.

A relativistic Hartree-Fock approach including core-polarization effects, on the one hand, and a purely relativistic multiconfiguration Dirac-Fock method, on the other hand, have been used for the calculations. The accuracy of the present set of results has been assessed through comparisons with radiative lifetime measurements obtained by beam-foil spectroscopy. A good agreement between theory and experiment is observed for most of the levels. A new set of transition probabilities is proposed for 169 transitions of Xe VII and 45 transitions of Xe VIII.

Their accuracy has been evaluated through comparisons with lifetimeme asurements for 11 levels performed using beams of Xeþ ions produced by a 2 MVV an de Graaff accelerator.

The beam-foil source can produce spectra of almost every ion and allows easy measurement of atomic lifetimes of excited levels. Beam-foil spectra have some unique characteristics that made them valuable tool for the term analysis of highly charged ions. As an example, we will describe the work undertaken at Liège on Ne IV and Ne V. Beam-foil is still the only general method for measuring the lifetime of atomic levels in highly charged ions. However, the accuracy of the classical beam-foil method is limited by the non-selective broadband excitation in the foil that populates almost all excitation levels up to very high energy and corrupts by cascading phenomena the normal single-exponential decay curves. We will describe some techniques that have been invented to obviate this infamous “cascading effect”, especially the beam-foil-laser spectroscopy method recently developed in our laboratory. We will present an overview of the beam-foil spectroscopy research performed at the University of Liège together with other recent trends in the field of fast-beam spectroscopy. [less ▲]
