Poder político, território e crise ambiental na Colômbia

Political power, territory and environmental crisis in Colombia. We describe some forms of operation of the political power of the Colombian State and their impacts on the territory. The analysis uses some results of a doctoral research that sought to understand the institutional and regulatory foundations and the water management practices in two metropolitan areas of South America, Cali in Colombia, and Campinas in Brazil. The theoretical framework, primarily based on critical thought, starts by making an approach to the concept of power and then links it with the concepts of territory and governance. We present empirical evidence on how the political power of the Colombian State operates on the environmental institutional structure. We concluded that the authoritarian interference of the executive power has generated crisis on the institutional framework and facilitated the advancement of the neo-liberal capitalist model.

Brucella ovis: InvasãO, tráfego, fatores de virulência e resposta imune

Brucellosis remains an economic problem in animals and public health. Worldwide ovine brucellosis caused by Brucella ovis is considered a major cause of infertility in sheep. The factors responsible for persistence of the agent are not known, as well as the mechanisms involved in immune defense and possibly the persistence of the agent. Brucella spp. induces moderate inflammatory response. The nature of the intracellular agent stimulates immune response of the type 1 helper T lymphocytes. Studies of the pathogenesis of ovine brucellosis are scarce. Recent developments have shown that the inflammatory response induced by moderate brucelas represent probably the result of an attempt to escape the immune response and suppression of host immune response. Were reviewed by the mechanisms described by brucelas and Brucella ovis for penetration into the host, escape of the immune response and the immune response generated by the infection.

A anatomia e o ensino de anatomia no Brasil: a escola boveriana

There is little scholarly research on the history, teaching and research of human anatomy in Brazil. A broader vision of the progress of anatomy under different circumstances in the country is virtually non-existent, leaving researchers keen to study the subject insecure. This is compounded by the fact that the data available are not always reliable. This text retraces the development of the discipline of anatomy and its research and education in Brazil in general and São Paulo state in particular, which can largely be reduced to the action of the self-proclaimed Boverian school of anatomy, founded by Italian physician Alfonso Bovero at the same time as the Medical Faculty of the University of São Paulo.

Questionário Atitudes de Segurança: adaptação transcultural do Safety Attitudes Questionnaire - Short Form 2006 para o Brasil

O objetivo deste estudo foi realizar a adaptação transcultural do Safety Attitudes Questionnaire - Short Form 2006 para o Brasil. O instrumento foi aplicado em seis hospitais de três Regiões do Brasil. Foi realizada a validade de conteúdo, face e de construto. A análise da confiabilidade do instrumento foi realizada por meio da análise da consistência interna dos itens por meio do alfa de Cronbach. A amostra do estudo foi composta por 1.301 profissionais das enfermarias clínicas e cirúrgicas de seis hospitais. A análise confirmatória mostrou que o ajuste do modelo final dos 41 itens foi considerado satisfatório. Aversão do instrumento em Português apresentou alfa de 0,89. As correlações item/total entre os domínios foram consideradas de moderada a forte, com exceção do domínio percepção do estresse. Conclui-se, portanto, que a versão do instrumento adaptada para o Português é considerada válida e confiável nesta amostra.

Cross-cultural adaptation of the Safety Attitudes Questionnaire - Short Form 2006 for Brazil

The objective of this study was to perform a cross-cultural adaptation of the Safety Attitudes Questionnaire - Short Form 2006 for Brazil. The instrument was applied in six hospitals in three regions of Brazil. Content, face, and construct validity was performed. Analysis of the instrument's reliability was performed by verifying the items' internal consistency through Cronbach's alpha. The sample was composed of 1301 professionals working in clinical and surgical wards of six hospitals. Confirmatory analysis showed that the model including 41 items was satisfactory. The Portuguese version presented an alpha of 0.89. The item-total correlations among the domains were moderate to strong, except for the domain Stress Recognition. We concluded that the instrument's version adapted to Portuguese and applied in our sample is valid and reliable.

Combinatorial and Robust Optimisation Models and Algorithms for Railway Applications

This thesis deals with an investigation of combinatorial and robust optimisation models to solve railway problems. Railway applications represent a challenging area for operations research. In fact, most problems in this context can be modelled as combinatorial optimisation problems, in which the number of feasible solutions is finite. Yet, despite the astonishing success in the field of combinatorial optimisation, the current state of algorithmic research faces severe difficulties with highly-complex and data-intensive applications such as those dealing with optimisation issues in large-scale transportation networks. One of the main issues concerns imperfect information. The idea of Robust Optimisation, as a way to represent and handle mathematically systems with not precisely known data, dates back to 1970s. Unfortunately, none of those techniques proved to be successfully applicable in one of the most complex and largest in scale (transportation) settings: that of railway systems. Railway optimisation deals with planning and scheduling problems over several time horizons. Disturbances are inevitable and severely affect the planning process. Here we focus on two compelling aspects of planning: robust planning and online (real-time) planning.

Aufbau des Crystal-Ball-Detektorsystems und Untersuchung der Helizitätsasymmetrie in gamma p p pi 0 pi 0

Seit Frühjahr 2004 wird der Crystal Ball-Detektor am Photonenstrahl des Mainzer Mikrotrons für Koinzidenzexperimente zur Untersuchung der Struktur der Nukleonen genutzt. Aufbau und Inbetriebnahme des Kalorimeters, insbesondere der neuen Detektorelektronik, bilden einen Schwerpunkt dieser Arbeit. Komponenten wurden neu konstruiert oder auf ihre Verwendbarkeit geprüft und nögenfalls modifiziert. Nach erfolgreichem Abschluss der Aufbauphase wurden Experimente zur Produktion von $pi$- und $eta$-Mesonen am Proton mit mehr als 2500 Stunden Strahlbetrieb durchgeführt. Den zweiten Schwerpunkt der Dissertation bildet die erstmalige Messung der Helizitätsasymmetrie I$^odot$ in der Photoproduktion zweier neutraler Pionen. Zum Verstädnis des Anregungsspektrums der Nukleonen müssen Experimente mit polarisierten Photonen und/oder polarisierten Targets durchgeführt werden. Da Modelle trotz unterschiedlicher Annahmen unpolarisiert gemessene Größen vergleichbar gut reproduzieren, ist die Bestimmung der auf Modellunterschiede empfindlichen Polarisationsobservablen unumgäglich. Im Gegensatz zur Einpionproduktion tritt in der Zweipionproduktion eine Einfachpolarisationsobservable auf, die mit zirkular polarisierten Photonen am unpolarisierten Proton gemessen werden kann. Diese wurde in der Reaktion $gamma$ p $rightarrow$ p $pi^0$ $pi^0$ und in $gamma$ p $rightarrow$ p $pi^+$ $pi^-$ energie- und winkelabhägig bestimmt. Die Ergebnisse weichen stark von den Modellvorhersagen ab.
