Effects of reusing coir-based substrates with municipal compost and biochar on ...

This research aimed to evaluate the influence of reusing as growing media, five blends of coir, with municipal organic compost, biochar, perlite and pine bark on growth and phytochemical accumulation in lettuce. The tested growing media blends were coir (new) and four reused mixtures: coir: biochar: perlite, coir: compost: perlite, coir: biochar: pine bark, and coir: compost: pine bark. All mixtures had already...

Occupational exposure to metals and PAHs: combining literature-based exposure a...

The environment within industrial settings is commonly characterized by the existence of a complex mixture of chemicals from different raw materials and transformation processes. Occupational co-exposure to chromium (Cr), Nickel (Ni), and Polycyclic Aromatic Hydrocarbons (PAHs) may occur in diverse workplaces, such as aeronautic and waste management, (e.g incineration) sectors. Such co-exposure raises concern i...

Glycans as Key Checkpoints of T Cell Activity and Function

The immune system is highly controlled and fine-tuned by glycosylation, through the addition of a diversity of carbohydrates structures (glycans) to virtually all immune cell receptors. Despite a relative backlog in understanding the importance of glycans in the immune system, due to its inherent complexity, remarkable findings have been highlighting the essential contributions of glycosylation in the regulatio...

Metabolic control of T cell immune response through glycans in inflammatory bow...

Mucosal T lymphocytes from patients with ulcerative colitis (UC) were previously shown to display a deficiency in branched N-glycosylation associated with disease severity. However, whether this glycosylation pathway shapes the course of the T cell response constituting a targeted-specific mechanism in UC remains largely unknown. In this study, we demonstrated that metabolic supplementation of ex vivo mucosal T...

Revisiting crude and standardized mortality ratios : which ones to assess healt...

Background: Standardized Mortality Ratios-SMR are often used to assess performance of health systems. Age adjusted SMR are rates one would expect to observe in the study population if it had the same age distribution as the standard year itself. SRM are thus artificial data, appropriate to compare groups (countries, for example) or time trends, isolating this analysis from age effects and its variability over t...

Assessing the performance of the FAO Aquacrop model to estimate maize yields an...

tSeveral maize field experiments, including deficit and full irrigation, were performed in Ribatejo region,Portugal and were used to assess water stress impacts on yields using the AquaCrop model. The modelwas assessed after its parameterization using field observations relative to leaf area index (LAI), cropevapotranspiration, soil water content, biomass and final yield data and also using default parameters. ...

Recent improvements in the Broadband seismic networks in Portugal

Portugal, in spite of the significant earthquake region, (e.g.: Borges et al., 2001) has been operating a limited number of broadband digital seismic instruments. The older BB seismic station in a systematic and continuous operation on the country is MTE, belonging to GEOFON and locally supported by IM, which is working since 1997. To efficiently carry out the task of develop the Broadband Portuguese seismic ne...

Relatório do Grupo de Trabalho de Estatísticas da Saúde

O Grupo de Trabalho de Estatísticas de Saúde - GTES foi criado no âmbito do Conselho Superior de Estatística (Secção Permanente de Estatísticas Sociais), com o objetivo de identificar e redefinir o conteúdo do sistema de informação das estatísticas oficiais de saúde nos domínios “estado de saúde e seus determinantes”, “cuidados de saúde”, e “causas de morte”. Para atingir esse objetivo o Grupo, em primeiro luga...

Influence of soil water content and atmospheric conditions on leaf water potent...

Abstract In this study, the influence of soil and atmosphere conditions on noon and basal leaf water potential of vines ‘‘Touriga Nacional’’ in the Da˜o region submitted to different irrigation treatments is analysed. Both indicators showed to be dependent on environmental conditions at the time of measurement. Leaf water potential at noon of fully watered plants was linearly related with atmospheric conditions...
