Comparative studies on energy efficiency and GHG emissions between conventional...

Nowadays, traditional farming based on achieving high yields using high inputs, shifts gradu-ally towards maximum possible crop yield using minimal inputs in an optimized way or to-wards organic farming. This is usually accomplishing by low yield of high quality products without using conventional agrochemicals (i.e. fertilizers, pesticides). In general, this last ap-proach leads to lower energy consumption per...

Ganglioneuroma da Supra-renal – relato de caso clínico

INTRODUÇÃO Os ganglioneuromas da supra-renal são tumores raros, benignos, bem diferenciados e têm origem na crista neural. A maioria dos doentes com ganglioneuroma da supra-renal são assintomáticos, e grande parte destes tumores são não secretores. Geralmente, são encontrados acidentalmente em exames de imagem abdominal por outro motivo. CASO CLÍNICO Sexo feminino, 53 anos, com antecedentes de hipert...

Ganglioneuroma of the Adrenal Gland - a case report

Introduction: The adrenal ganglioneuroma are rare, benign and well differentiated tumors that arise from neural crest tissue. Most patients with adrenal ganglioneuroma are asymptomatic, and most of these are non-secreting tumors. They are usually found incidentally on abdominal imaging study for another reason. Case: A 53-year-old female, with a history of hypertension diagnosed at age 30, dyslipidaemia, depr...

Abordagem de Adenocarcinoma do Seio Maxilar a Propósito de um Caso Clínico

Estudo Prospectivo Referente aos Principais Factores de Risco de Patologia Card...

Introdução: é actualmente consensualmente reconhecido que a aterosclerose tem a sua origem na idade pediátrica ainda que as expressões clínicas da doença cardio-cérebro-vascular se manifestem apenas na idade adulta. Entre os seus principais factores de risco apontam-se entre outros, a obesidade, a hipertensão e um perfil lipídico sérico adverso. Tais factores de risco evidenciam uma notória estabilidade relativ...

Energia, ambiente, economia e olival no Alentejo. Estudo preliminar

Prevê-se que o consumo de energia na agricultura irá aumentar significativamente nos próximos anos com a intensificação dos sistemas de produção. As melhorias na eficiência energética dos sistemas de produção estão relacionadas com a redução do uso de energia para um determinado serviço ou nível de actividade, ou a um aumento de produtividade para a mesma energia consumida. Os sistemas de produção agrícola estã...

Influence of availability of shade on testicular characteristics of Santa Ines ...

The purpose of this study was to evaluate the effects of availability of artificial shading on testicular and seminal characteristics of Santa Ines crossbred rams. Twelve 8 month old rams at 38.1 ± 5.2 kg average weight, were used in a total random design with two treatments: areas with and without available artificial shading (black polyethylene mesh screen for a 50% reduction of solar radiation). The scrotal ...

Agriculture and energy efficiency in portuguese agriculture and trade-offs with...

This paper aims to present and discuss an economic and environmental analysis based on case studies for selected Portuguese agriculture production systems which show potentials and constraints of energy efficiency measures in agriculture with respect to the specific environment of Portugal. Results are the Portuguese part of one work package of AGREE (AGRiculture and Energy Efficiency) an European project. It i...

Otoczenie zewnetrzne efektywnosci energetycznej w rolnictwie – studium przypadk...

Until recently energy efficiency in agriculture has received little attention. Nevertheless, energy consumption in agriculture is considerable, especially when indirect energy use is taken into account. AGREE has the objective of showing the potential of short term energy efficiency gains and the promise of a long term potential. Environmental effects of savings on direct and indirect energy use in agriculture ...

Dzialania energooszczedne w rolnictwie (Energy saving measures in agriculture)

The reduction of energy inputs in agricultural production is a process of practical implementation of a set of energy saving (ES) measures associated with a given type of production, farm infrastructure and managerial or organizational activities. In six national reports from Finland, Germany, Greece, the Netherlands, Poland and Portugal for 13 subsectors of agriculture, 481 ES measures in total were identified...
