Generate disaggregated soil allocation data using a Minimum Cross Entropy Model
Montado ecosystem in the Alentejo Region, south of Portugal, has enormous agro-ecological and economics heterogeneities. A definition of homogeneous sub-units among this heterogeneous ecosystem was made, but for them is disposal only partial statistical information about soil allocation agro-forestry activities. The paper proposal is to recover the unknown soil allocation at each homogeneous sub-unit, disaggregating a complete data set for the Montado ecosystem area using incomplete information at sub-units level. The methodological framework is based on a Generalized Maximum Entropy approach, which is developed in thee steps concerning the specification of a r order Markov process, the estimates of aggregate transition probabilities and the disaggregation data to recover the unknown soil allocation at each homogeneous sub-units. The results quality is evaluated using the predicted absolute deviation (PAD) and the "Disagegation Information Gain" (DIG) and shows very acceptable estimation errors
COPD and cardiovascular disease
COPD is one of the major public health problems in people aged 40 years or above. It is currently the 4th leading cause of death in the world and projected to be the 3rd leading cause of death by 2020. COPD and cardiac comorbidities are frequently associated. They share common risk factors, pathophysiological processes, signs and symptoms, and act synergistically as negative prognostic factors. Cardiac disease includes a broad spectrum of entities with distinct pathophysiology, treatment and prognosis. From an epidemiological point of view, patients with COPD are particularly vulnerable to cardiac disease. Indeed, mortality due to cardiac disease in patients with moderate COPD is higher than mortality related to respiratory failure. Guidelines reinforce that the control of comorbidities in COPD has a clear benefit over the potential risk associated with the majority of the drugs utilized. On the other hand, the true survival benefits of aggressive treatment of cardiac disease and COPD in patients with both conditions have still not been clarified. Given their relevance in terms of prevalence and prognosis, we will focus in this paper on the management of COPD patients with ischemic coronary disease, heart failure and dysrhythmia.Novartis Portugal

Multi-objective water allocation in the Alqueva Region
Alqueva dam in the Alentejo Region was developed to solve water scarcity in
the South ofPortugal and to ensure pennanent availability ofwater for household
and industrial consumption, irrigation, production of electric energy, ecological
and environrnental purposes. Competition among some ofthese multiple
water uses requires an integrated management framework. This paper uses
Interactive Decision Maps (IDM) technique to explore and achieve efficient
and equitable water allocation combinations taking into account those multipIe
goals and principIes of good water govemance. Results show that multiple
water uses do constrain full economic impact for agriculture and suggest that
integrated management frameworks and policies are needed at regional territoriallevel
to reach a compromise between competing economic, social and
environrnental goals and achieve project global development benefits
Resistência a inseticidas em populações de Tibraca limbativentris.
O objetivo desse trabalho foi determinar a curva de dose-resposta para verificar a suscetibilidade do percevejo do colmo Tibraca limbativentris provenientes dos estados de Goiás e Pará aos inseticidas lambda-cialotrina e endosulfan
Curva de dose-resposta a inseticidas para o percevejo dos grãos Oebalus poecilus (Hemiptera: Pentatomidae).
Esse trabalho objetivou determinar a curva de dose resposta para a população padrão de suscetibilidade de O. poecilus aos inseticidas endosulfan e lambda-cialotrina, para posterior estudo de detecção em outras populações desta espécie nas principais regiões produtoras de arroz
Mammal traits and soil biogeochemistry: Functional diversity relates to composition of soil organic matter
Mammal diversity affects carbon concentration in Amazonian soils. It is known that some species traits determine carbon accumulation in organisms (e.g., size and longevity), and are also related to feeding strategies, thus linking species traits to the type of organic remains that are incorporated into the soil. Trait diversity in mammal assemblages – that is, its functional diversity – may therefore constitute another mechanism linking biodiversity to soil organic matter (SOM) accumulation. To address this hypothesis, we analyzed across 83 mammal assemblages in the Amazon biome (Guyana), the elemental (by ED‐XRF and CNH analysis) and molecular (FTIR‐ATR) composition of SOM of topsoils (401 samples) and trait diversity (functional richness, evenness, and divergence) for each mammal assemblage. Lower mammal functional richness but higher functional divergence were related to higher content of carbonyl and aliphatic SOM, potentially affecting SOM recalcitrance. Our results might allow the design of biodiversity management plans that consider the effect of mammal traits on carbon sequestration and accumulation in soils.Xunta de Galicia | Ref.

Aspectos fitossanitários em olival na Beira Interior Norte e na Beira Interior Sul
Comunicação oral apresentada no 6.º Encontro Nacional de Protecção Integrada que decorreu em Castelo Branco, na Escola Superior Agrária do Instituto Politécnico de Castelo Branco, no âmbito do painel sobre o OlivalPara uma análise dos problemas fitossanitários do olival na Beira Interior foram realizados observações e
estimativas do risco, em 2002, em quatro olivais na Beira Interior Norte e outros quatro na Beira Interior Sul.
Os olivais da Beira Interior Norte ficam localizados nos concelhos de Seia, Pinhel, Guarda e Figueira de
Castelo Rodrigo e os da Beira Interior Sul nos concelhos de Penamacor, Fundão, Proença-a-Nova e Vila Velha
de Ródão. Os inimigos mais importantes e para que foram feitas estimativas do risco foram: gafa, olho de
pavão, mosca-da-azeitona, traça-da-oliveira e cochonilha-negra.
Em todos os olivais foram encontrados todos os inimigos avaliados, mas com pouca expressão para o olho de
pavão nos olivais da cultivar Galega. Os dados da estimativa do risco são apresentados, assim como o número
das intervenções químicas que foram necessárias realizar. São discutidas e comparadas as intervenções
realizadas
