An exact master equation for the system-reservoir dynamics under the strong coupling regime and non-Markovian dynamics

In this paper we present a method to derive an exact master equation for a bosonic system coupled to a set of other bosonic systems, which plays the role of the reservoir, under the strong coupling regime, i.e., without resorting to either the rotating-wave or secular approximations. Working with phase-space distribution functions, we verify that the dynamics are separated in the evolution of its center, which follows classical mechanics, and its shape, which becomes distorted. This is the generalization of a result by Glauber, who stated that coherent states remain coherent under certain circumstances, specifically when the rotating-wave approximation and a zero-temperature reservoir are used. We show that the counter-rotating terms generate fluctuations that distort the vacuum state, much the same as thermal fluctuations.Finally, we discuss conditions for non-Markovian dynamics

Quanto vale o Pantanal? A valoração ambiental aplicada ao bioma Pantanal.

As informações contidas nesta publicação buscam assegurar a efetividade de políticas que garantam a sustentabilidade do bioma e ao mesmo tempo assegurem que a tomada de decisões em projetos para seu desenvolvimento, sejam coerentes e racionais. Neste sentido, é necessário que os múltiplos usos e valores dessas áreas úmidas sejam reconhecidos e considerados, mais particularmente o seu valor econômico, já que as decisões de planejamento de uso da terra tradicionalmente se baseiam em considerações econômicas. Os autores mostram que as estimativas desses valores devem estar baseadas em técnicas adequadas, pois os métodos tradicionais não conseguem determinar os benefícios de muitas funções ambientais ou os custos de sua perda. Também reportam que por meio de tais técnicas, conhecidas como métodos de valoração ambiental, é possível determinar o valor monetário dos bens e serviços ambientais em relação a outros bens e serviços da economia, e dessa forma, refletir seus valores sociais e não meramente seus valores de mercado. Este trabalho explica de forma simples os fundamentos da valoração econômica ambiental e seu papel na tomada de decisões sobre os usos do Pantanal e leva o leitor a pensar na valoração econômica de ecossistemas como mais um elemento a ser considerado quando se tomam decisões de uso de áreas úmidas.bitstream/CPAP-2010/57310/1/DOC105.pd

Rentabilidade da pecuária tradicional do Pantanal para fazendas com e sem pastagens cultivadas.

Dados primários sobre a pecuária pantaneira foram obtidos de questionários enviados via correio a pecuaristas do Pantanal, seguindo convenções metodológicas. O questionário foi elaborado de modo a obter informações que permitissem descrever e caracterizar de forma geral a pecuária pantaneira, identificar diferenças entre sistemas de produção e, particularmente, para permitir investigar a rentabilidade das fazendas considerando dois níveis tecnológicos: com e sem pastagens cultivadas. Primary data on Pantanal livestock were obtained from questionnaires sent by mail to ranchers in the Pantanal. The questionnaire was prepared in order to obtain information enabling to describe and characterize in a general way the Pantanal livestock, identifying differences between production systems and particularly to allow to investigate the profitability of farms considering two technological levels: with and without cultivated pastures

Ornithological bibliography of the Azores

Only scientific publications up to 1980 are included in this bibliography. Other old narrations containing information on Azorean ornithology are being assembled for future publication. Certain unpublished works will also be dealt with. The part for consultation has been arranged in three sections. The first presents a numbered list of papers and books in chronological order up to 1980. Last minute alterations obliged us to eliminate some items and to use «bis» for repeated numbers in some cases. The second section consists of the list of papers under their authors in alphabetical order. Finally, the third section consists of an index of the scientific names of the species cited. The index contains three types of entries: - The names of the genera, in capital letters, followed by the specific and subspecific names, which lead to their numbers in the chronological list. The latter are accompanied by the relevant page numbers, in brackets. - The names of the species, in small letters in bold-faced type, lead to the names of the genera. - The names of the subspecies, in normal small letters, lead to the genera and species. Example: Fringilla coelebs moreletti entered under FRINGILLA, coelebs and moreletti, with the bibliographical references only under the complete name. Papers of Nºs. 17, 41, 72, 74, 76 have not been consulted by us; all other works are available in our library

Digital PCR methods improve detection sensitivity and measurement precision of low abundance mtDNA deletions

Mitochondrial DNA (mtDNA) mutations are a common cause of primary mitochondrial disorders, and have also been implicated in a broad collection of conditions, including aging, neurodegeneration, and cancer. Prevalent among these pathogenic variants are mtDNA deletions, which show a strong bias for the loss of sequence in the major arc between, but not including, the heavy and light strand origins of replication. Because individual mtDNA deletions can accumulate focally, occur with multiple mixed breakpoints, and in the presence of normal mtDNA sequences, methods that detect broad-spectrum mutations with enhanced sensitivity and limited costs have both research and clinical applications. In this study, we evaluated semi-quantitative and digital PCR-based methods of mtDNA deletion detection using double-stranded reference templates or biological samples. Our aim was to describe key experimental assay parameters that will enable the analysis of low levels or small differences in mtDNA deletion load during disease progression, with limited false-positive detection. We determined that the digital PCR method significantly improved mtDNA deletion detection sensitivity through absolute quantitation, improved precision and reduced assay standard error

On the uses and functions of 'strategic partnership' in international politics: Implications for agency, policy and theory

de Moraes y Blanco LF. On the uses and functions of 'strategic partnership' in international politics: Implications for agency, policy and theory. Bielefeld: Universitätsbibliothek Bielefeld; 2015.In the last decades the usage of ‘strategic partnership’ as a conceptual framework for cooperative relationships between international political actors has been increasing. However, there is a lack of understanding both in the academia and within the policy-making community regarding the meaning of this expression. This thesis discusses the nature and uses of concept of ‘strategic partnership’ in international politics. Based on ontological, epistemological and methodological assumptions from the Philosophy of Language, Pragmatics, Social Constructivism, the English School of International Relations and Positioning Theory, I present a pluralist theoretical framework to assess the uses of ‘strategic partnership’ in international politics not as a descriptive concept based on fixed properties but as a fluid political concept. I analyze the uses made of ‘strategic partnership’ in the context of the relations between the EU and the BRIC countries (Brazil, Russia, India and China) and draw important conclusions for understanding not only the EU’s strategic partnerships but also the uses of ‘strategic partnership’ in the language of international politics. I demonstrate that ‘strategic partnership’ is turning into a foreign policy concept with three functions. Firstly, it is a label of demarcation and hierarchization of partners. Secondly, it is a normative instrument through which the EU attempts to advance and implement its ‘structural foreign policy’, associated with values like ‘democracy’ and ‘human rights’ and the norm of ‘effective multilateralism’. Thirdly, ‘strategic partnership’ is a constitutive ‘speech act’ used to constitute and reconstitute the rules of engagement between international political actors in terms of shared goals, internal hierarchy of the relationship, and references to particular sets of values and notions of rivalry and friendship. Finally, the thesis assesses the implications of a language-based approach to ‘strategic partnership’ for agency, policy and theory
