«Los Albuquerque Coelho, siglos XVI-XVII. Prácticas sociales y retórica nobiliária»

Este estudo parte da hipótese de que os serviços militares, a linhagem e a cultura católica se mantiveram como os referentes centrais do ethos nobiliario em Portugal e em Espanha no século XVII, com pouca diferenças relativamente ao conjunto de valores elaborado pelo próprio grupo desde a época medieval. O estudo de caso incide sobre a família dos Albuquerque Coelho desde o século XVI até finais do XVII, acompanhando o seu multifacetado processo de ascensão social, onde pontuam a sua implantação no Brasil (Pernambuco) e as opções políticas por eles tomadas na sequência do 1º de Dezembro de 1640

Influência da gestão do habitat na distribuição e abundância do coelho-bravo no Sítio Natura 2000 Monchique

O coelho-bravo, devido à sua importância ecológica e económica, tem sido alvo de diversos planos de gestão e vários esforços têm sido empreendidos no sentido de contrariar o decréscimo das suas populações. Este estudo foi realizado em três zonas de caça do Sítio Monchique e o principal objectivo é determinar se as medidas de gestão implementadas influenciam a distribuição e abundância da espécie na área de estudo. A abundância relativa foi interpolada com o método "Inverso do Peso da Distância" {IDW), e as relações entre presença de coelho e os descritores ambientais foram analisadas através de Modelos Lineares Generalizados (GLM). Os resultados da modelação estatística mostraram que as medidas de melhoria de habitat parecem ter sido determinantes para um aumento da área de distribuição do coelho-bravo nos locais intervencionados. São propostas novas medidas de gestão, cujo objectivo será promover a continuação do aumento da ocorrência e abundância da espécie neste local. /ABSTRACT: The wild rabbit, due to its ecological and economical role, has been the target of several management plans and considerable efforts have been made to enhance its populations. This study was held in three game estates located inside Monchique Natura 2000. Site and aims to determine if the habitat management actions implemented in the study area influence rabbit distribution and abundance. The relative abundance was interpolated to all study area with lnverse Distance Weight method {IDW} and the relationships between rabbit presence and the environmental descriptors were evaluated with Generalized Linear Models (GLM). The results of the statistical modelling showed that the management actions seem to have contributed significantly to an enhancement on the rabbit occurrence in the studied game estates. Several new management actions are proposed with the aim to continue to increase rabbit occurrence and abundance in this site.

Resposta do Olival Intensivo e Super-Intensivo a Dois Regimes de Rega: Parâmetros Fisiológicos, Produção e Qualidade

O olival de regadio tem tido grande expansão nos últimos anos no Alentejo, sendo a administração da rega mais adequada às necessidades hídricas um dos fatores determinantes da sua boa gestão. No presente trabalho, avaliou-se a resposta de duas variedades de Olea europaea, Cobrançosa e Arbequina, em regime intensivo e super- intensivo, respetivamente, a duas dotações de rega, a normalmente utilizada pelo agricultor (RA) e outra experimental, com dotações acima (RA+) ou abaixo (RA−) das praticados em RA. Mediram-se os principais parâmetros hídricos das plantas e o teor em clorofilas, e registou-se a assinatura espectral em folhas adultas e jovens, ao meio- dia solar, em três épocas do ano, primavera, final do verão e inverno de 2011. Em Outubro foi feita a colheita, tendo-se quantificado a produção em termos de produção total e teor de óleo na matéria seca, e a qualidade do azeite em termos de acidez e oxidação. Face aos resultados, conclui-se que no olival intensivo de Cobrançosa, na rega experimental (RA+), acima da praticada pelo agricultor, não se verificou diferenças significativas na produção total nem no teor de óleo na matéria seca. Não se verificaram também diferenças significativas entre as regas nos parâmetros hídricos avaliados. Quanto ao olival super-intensivo de Arbequina, a rega experimental (RA−), deficitária relativamente à do agricultor (RA), acarretou menor produção, associada a menor teor relativo de água nas folhas, potenciais hídricos mais negativos e menor condutância estomática no final do verão e inverno, mantendo-se no entanto o teor de óleo nos frutos. O teor em clorofilas e alguns índices de vegetação foram influenciados pelo regime de rega apenas em algumas das datas. Nos dois olivais, as regas experimentais não influenciaram a qualidade do azeite, tendo-se obtido azeites extra virgem com propriedades semelhantes aos das modalidades RA. O estudo prossegue em 2012.

Pesquisa de Campylobacter fetus em amostras prepuciais de touros da região do Alentejo

A bactéria Campylobacter fetus divide-se em duas subespécies C. fetus fetus (Cff) e C. fetus venerealis (Cfv). Cfv é o agente patogénico responsável pela campilobacteriose genital bovina (CGB), uma doença que provoca infertilidade em vacas. Cff pode provocar abortos esporádicos, mas não provoca CGB. Neste trabalho procedeu-se à pesquisa de C. fetus por imunofluorescência direta (IFD) em 117 amostras prepuciais, recolhidas por raspagem, de touros pertencentes a 25 explorações na região do Alentejo. A prevalência real de CGB na amostra, considerando a sensibilidade e especificidade do teste, foi de 52,89% de animais e 80% de explorações. Foi também realizada uma comparação entre dois testes de diagnóstico de CGB, a IFD e o isolamento bacteriológico. O isolamento bacteriológico foi difícil de executar e a presença de bactérias contaminantes foi bastante problemática, levando a resultados falso-negativos. A sua correlação com a IFD foi muito baixa, tendo esta revelado ser muito mais sensível; #### Abstract Search for Campylobacter fetus in preputial samples of bulls from Alentejo region The bacteria Campylobacter fetus comprises two subspecies, C. fetus fetus (Cff) and C. fetus venerealis (Cfv). Cfv is the pathogen responsible for bovine genital campylobacteriosis (BGC), a disease that causes infertility in cows. Cff may lead to sporadic miscarriages, but does not cause BGC. In this work we searched for C. fetus by direct immunofluorescence (DIF) in 117 preputial samples, collected by scraping, from bulls from Alentejo region. The actual prevalence of BGC, considering the sensitivity and specificity of the test was 52.89% of animals and 80 % of farms. It was also performed a comparison between two BGC diagnostic tests, bacterial isolation and DIF. The bacterial isolation was difficult to perform and the presence of bacterial contaminants was very problematic, leading to false-negative results. The presence of bacterial contaminants in bacterial isolation was problematic, leading to false-negative results. Its correlation with DIF was quite low, and DIF proved to be much more sensitive.

SHORT-TERM EFFECTS OF SALINITY ON SOME PHYSIOLOGICAL PARAMETERS OF YOUNG OLIVE TREES OF ARBEQUINA, COBRANÇOSA AND GALEGA VARIETIES

SHORT-TERM EFFECTS OF SALINITY ON SOME PHYSIOLOGICAL PARAMETERS OF YOUNG OLIVE TREES OF ARBEQUINA, COBRANÇOSA AND GALEGA VARIETIES Ana Elisa Rato1,4, Renato Coelho1, Margarida Vaz1, Teresa Carola2, Dália Barbosa2, Nádia Silva1, José dos Santos2, Lourenço Machado2, João Godinho2, Luzia Ruas2, Margarida Barradas2, Hernani Pereira2, Sara Porfírio4 1 ICAAM, Universidade de Évora, Apartado 94, 7002-554 Évora, Portugal 2 Master students, Universidade de Évora, Apartado 94, 7002-554 Évora, Portugal 3 Ph.D. student, Universidade de Évora, Apartado 94, 7002-554 Évora, Portugal 4 aerato@uevora.pt Due to the desertification in some regions, the interest in plant’s tolerance to salinity has been increasing, as this response is determining for plant survival in stress conditions. This work reports the investigation of tolerance to salt in two year-old olive trees (Olea europaea L.) of three varieties, Arbequina, Cobrançosa and Galega vulgar. Plants were grown in 10 L plastic pots containing approximately 9 Kg of a sandy granitic soil, on a greenhouse. For 3 months (from the beginning of February to the end of April 2012), they were subjected to three levels of salinity in the irrigation water, 0 mM, 80 mM and 200 mM NaCl (6 plants per salinity level in a total of 18 plants of each variety),. Stomatal conductance (gs) and relative leaf chlorophyll content were assessed on each plant in February, March and April. Mid-day leaf water potential () and soil salinity were measured at the end of the experiment (April). On average, concerning all treatments and dates of determination, stomatal conductance of Arbequina and Galega vulgar was quite similar, around 40 mmol m-2 s-1, but Cobrançosa had a value of gs 36% higher, almost 50% higher (61 mmol m-2 s-1) when compared with the controls (0 mM salt) of the other two varieties. In percentage of controls, there was little difference in gs between varieties and between salinities during February and March. In contrast, in April, after about 90 days of exposure to salt, there was a clear decrease in gs with salt irrigation, proportional to salt concentration. Compared with controls, plants irrigated with 200 mM salt showed around 80% (Arbequina) or 85% (Cobrançosa and Galega vulgar) decrease in gs. Chlorophyll content of leaves showed less than 5% difference between varieties on the average of all treatments and dates of determination. During the course of this experiment, the salinity levels used did not show any relevant effect on chlorophyll content. Overall, at the end of the experimental period (April), leaf water potential () at midday was significantly higher in Cobrançosa (-1,4 MPa) than in Galega vulgar (-1,7 MPa) or Arbequina (-1,8 MPa), and salt decreased  of control plants (-1,25 MPa) by an average 30% (with 80 mM) and 65% (with 200 mM). At the end of the experiment, salinity in the soil irrigated with 0 mM, 80 mM or 200 mM NaCl was, on average of all varieties, 0,2 mS, 1,0 mS or 2,0 mS, respectively. Soil salinity was quite similar in Arbequina and Galega vulgar but about 35% lower in the pots of Cobrançosa, on average of all salt-irrigation levels. Plants of Cobrançosa had higher stomatal conductance, however they showed higher water potential and lower salinity in the soil. These apparently contradictory results seem to suggest that Cobrançosa responds to salt differently from the other two varieties. This issue needs further investigation.

Salinity-induced effects on transpiration rate, stomatal conductance and leaf area of three olive (Olea europaea L.) varieties

Transpiration of two year-old olive trees of three different varieties, Arbequina, Cobrançosa and Galega (18 trees per variety), irrigated with three levels of salt (0, 80 or 200 mM NaCl) for about 90 days, was measured by a gravimetric method. To determine leaf area, each tree was photographed from the side against a white background and the total area of each projected image was determined with ImageJ software. To calibrate these area determinations, one tree of each variety was subsequently stripped of all its leaves and its total leaf area was accurately measured. A correlation was then obtained between the area on the photograph of this particular tree and the total area of the detached leaves of the same tree. Using the leaf area determined by this procedure, transpiration rates of the trees could be calculated. Knowing leaf and air temperatures and RH, it was possible to determine the difference in molar fraction of water between the leaf and the air. Using this and the values of the transpiration rate, stomatal conductance could be calculated (gs calc) and compared with the conductance measured on the same trees with a porometer (gs). Actual leaf area of a plant was 1,40 (Arbequina), 1,42 (Cobrançosa) or 1,24 (Galega) times the area measured with ImageJ on the photograph of the same plant. Leaf area of the trees, on average of all salt irrigations, was significantly higher on Arbequina (0,187 m2) then on the other two varieties (0,138 m2 or 0,148 m2, for Cobrançosa or Galega, respectively), but did not differ significantly in percentage of controls (0 salt). On average of all three varieties, leaf area was also higher on plants irrigated without salt (0,181 m2) than on plants exposed to 80 or 200 mM NaCl (0,152 m2 or 0,140 m2, respectively), which did not differ between them. The same significant difference was observed when leaf area was expressed as percentage of controls. Transpiration rate was significantly higher on Cobrançosa (1,17 mmol m-2 s-1), on average of all treatments, but there were no significant differences between Arbequina (1,08 mmol m-2 s-1) and Galega (0,82 mmol m-2 s-1). In percentage of controls, there were no significant differences between varieties. Salt reduced significantly the transpiration rate in all varieties, both the actual and percentual values, to about 50% or 30% of controls when exposed to 80 mM or 200 mM NaCl, respectively. Stomatal conductance (gs), assessed by porometry, was significantly higher in control plants, mainly in Cobrançosa (102 mmol m-2 s-1), then in Arbequina (77 mmol m-2 s-1) and the lower values were found in Galega (51 mmol m-2 s-1). Salt reduced gs, on average of the three varieties to 30% or 10% of controls on exposure to 80 mM or 200 mM NaCl, respectively. Calculated (gs calc) and measured (gs) values of stomatal conductance showed a close relation between them (0,967, R2 = 0,837) which indicates this non-destructive method to determine whole-plant leaf area to be reasonably accurate.

On lattices from combinatorial game theory modularity and a representation theorem: Finite case

We show that a self-generated set of combinatorial games, S, may not be hereditarily closed but, strong self-generation and hereditary closure are equivalent in the universe of short games. In [13], the question “Is there a set which will give an on-distributive but modular lattice?” appears. A useful necessary condition for the existence of a finite non-distributive modular L(S) is proved. We show the existence of S such that L(S) is modular and not distributive, exhibiting the first known example. More, we prove a Representation Theorem with Games that allows the generation of all finite lattices in game context. Finally, a computational tool for drawing lattices of games is presented.

Estudo preliminar sobre a ação antimicrobiana de óleos essenciais sobre agentes etiológicos de mastite em ovelhas

The control of mastitis is currently reliant on antibiotic utilization. Nevertheless antibiotics overuse and use without criteria leads to the development of resistant strains with negative consequences both in animal and public health. Essential oils (EOs) are classified as GRAS (generally recognized as safe), are provided with antimicrobial properties and no resistance has been reported after use. The aim of this study was to evaluate the antimicrobial activity of EOs of aromatic herbs, growing wild in Alentejo region and widely used in Mediterranean food, against microorganisms isolated from ovine mastitic milk.

It also discusses the inclusion as the only way to achieve a more equitable society that promotes respect of citizenship and quality of life for all. A focus on training as an agent of change in the form of being, thinking, feeling and acting and the relentless pursuit by the development of a university fairer and more humane, seems to be the way to achieve the desideratum of an inclusive university.

Estratégia empresarial: contribuição para a análise estratégica das cooperativas vitivinícolas do Alentejo

O presente estudo tem como objetivos analisar a estratégia competitiva das adegas cooperativas do Alentejo, através da análise das ações que têm sido por elas desenvolvidas, propor linhas adicionais de ação estratégica e perspectivar as suas possibilidades de sucesso. A inovação e a flexibilidade das adegas cooperativas para se adaptarem ao crescente dinamismo dos contextos empresariais, conduziu a uma gestão mais profissional e a encarar a estratégia como necessária para uma maior competitividade. Nesse sentido, a cooperação entre as adegas cooperativas é vista como um meio de aumentar a competitividade no mercado internacional. A investigação permitiu constatar que o sector vitivinícola a nível mundial esta na fase de maturidade, com excesso de capacidade produtiva, procura global decrescente e queda de pregos, apresenta, no entanto, alterações significativas nos hábitos de consumo. As adegas cooperativas utilizam estratégias de diferenciação, apostam em produtos de qualidade e com elevados índices de notoriedade entre os consumidores. As principais diferenças competitivas entre elas estão relacionadas com a dimensão e a relação entre esta e a capacidade de recursos para investir ao nível do Marketing-Mix por forma a construir vantagens competitivas duradouras através da notoriedade dos seus vinhos. Para além disso, verifica-se também nas adegas de maior dimensão uma gestão estratégica mais orientada para a competitividade sustentável e maior visão estratégica. O método utilizado (estudo de caso comparativo, de natureza exploratória e, essencialmente qualitativo) não permite uma generalização extensiva dos seus resultados para além das cooperativas estudadas. Os resultados devem ser entendidos, de forma ponderada, no seu contexto específico e para os casos em concreto, pois, cada organização tem características únicas que influenciam o funcionamento da gestão. ABSTRACT - The present study has has been to analyse the competitive strategy of the Alentejo cooperative cellars, through the analysis of the shares that have been developed for the cooperative cellars, propose additional lines of strategic action and preview their possibility of success. The innovation and the flexibility of the cooperative cellars to the dynamic growth of the business contexts, accelerated shattering process of the enterprise contexts, lead to a more professional management and to face the strategy as necessary for a bigger competitiveness. In this direction, the cooperation between the cooperative cellars is seen as a way to increase the competitiveness in the international market. The inquiry allowed to evidence a world industry in maturity phase, with excess of productive capacity, presents a decreasing demand, alteration of the consumption habits and fall of the prices. The cooperative cellars use differentiation strategies, bet in products of quality and with raised indices of notoriety between the consumers. The main competitive differences between them are related with the dimension and the relation between this and the capacity of resources to invest to the level of Marketing-Mix for form to construct lasting competitive advantages through the notoriety of its wines. For moreover, a strategic management more guided for the sustainable competitiveness is also verified in the cellars of bigger dimension and bigger strategic vision. Due to the applied method (comparative case study, in searching manner and, essencialy qualitative) it cannot be purposed an extensive generalization of the results to another non-studied population. The results must be understood in a balanced way, in their Enterprise Strategy: Contribution for the Strategic Analysis of the Alentejo Wines Cooperatives specific context, and for real cases, since each company has its own features that influences the management work.

Response to salinity in young olive trees of three Iberian varieties

Soil salinization is a problem in the Mediterranean region. This paper reports a research on the response to salt in two year-old olive trees (Olea europaea L.) of three Iberian varieties: Arbequina, Cobrançosa and Galega Vulgar. Plants were grown in plastic pots containing approximately 9 Kg of a sandy granitic soil, on a greenhouse at the University of Évora since February 2010. The experiment went from February to April 2012. As a rule, plants were watered every other day alternating salt solution (0 mM, 80 mM or 200 mM NaCl) or tap water. After three months irrigation with the different NaCl solutions, soil electric conductivity and soil water content were significantly higher on salt-irrigated pots. Salt also decreased significantly stomatal conductance (gs) and mid-day leaf water potential (), Cobrançosa having in general higher gs and but lower SLA than the two other varieties. Chlorophyll content of leaves was not affected by salt after this three months exposure to NaCl but was significantly higher on Arbequina and lower on Cobrançosa. In general, hyperspectral reflectance indexes did not show significant correlations with salt irrigation, except for the Photochemical Reflectance Index (PRI) which was clearly lower on plants of all three varieties irrigated with salt. Interestingly, Cobrançosa showed frequently vegetation indexes different from the other two varieties.

Influence of Soil and Irrigation Management on the Quality of Seedless Crimson Table Grapes

The market for table grapes is moving into mass production of specialty seed-less grapes in covered areas, aiming at obtaining premium prices with early or late production of high quality products. Production of quality seedless grapes is not straightforward since it is requires the correct combination of various independent characteristics, such as color, sugars, size and quantity at the right moment for successful harvesting and marketing. The present study was carried out at the two largest Portuguese producers located in Alentejo, and has the objective of studying the effect of irrigation management strategies and two different soils on the various relevant parameters for successful production and marketing. The management strategies were the application of ten day stress at the end of the cycle, in order to promote early maturing of the grapes. Three different timings of the stress were applied. Soil moisture, sap flow, bark thickness, as well as leaf water potential, stomatal conductance and chlorophyll content were measured regularly during the production season. The results indicate that the roots explore a rather large soil volume and the plants can successfully withstand reasonable periods of drought without significant changes to the plant physiology. Additionally late rains can mask the effect of any farmer applied drought and invalidate any farmer induced stress to the plants. Water-logged soils tend to cause early onset of maturity, but cause the ripening stage to extend over a longer period of time, and thus, in effect result in a delay in the harvest date. Topography also has some effect on the ripening, since hot air tends to accumulate under the plastic at the higher areas of the field. This work is funded by PRODER, 4.1, within the scope of project MORECRIMSON

Turismo desportivo no concelho de Évora

Na divulgação de qualquer destino turístico é necessário ter em conta diversos fatores. Esta dissertação teve como principal objetivo analisar a procura e a oferta ao nível do turismo desportivo no concelho de Évora. Foi estudado o turismo desportivo no município de Évora, que é um dos maiores destinos turísticos da região Alentejo. Aplicando questionários de maneira a saber qual a opinião dos turistas relativamente a atividades desportivas praticadas neste destino. Foram ainda realizadas duas entrevistas a responsáveis da Câmara Municipal de Évora e ao Diretor de uma empresa de Animação Turística. A falta de estratégia no sector é evidenciada pelo facto dos visitantes não apresentarem como motivação primária a prática de atividades desportivas. Sendo o Turismo e o Desporto sectores económicos de grande importância em termos globais e locais, verificou-se que no concelho de Évora o Turismo Desportivo pode ser um grande agente de desenvolvimento em diversas áreas; Abstract: Sports Tourism in Évora Municipality The disclosure of any tourist destination should be taken into account several factors. This work aimed to analise the demand and supply in terms of sports tourism in Évora municipality.
