Pirólise de borras oleosas de petroleo utilizando nanomateriais

The oily sludge is a complex mix of hydrocarbons, organic impurities, inorganic and water. One of the major problems currently found in petroleum industry is management (packaging, storage, transport and fate) of waste. The nanomaterials (catalysts) mesoporous and microporous are considered promising for refining and adsorbents process for environment protection. The aim of this work was to study the oily sludge from primary processing (raw and treated) and vacuum residue, with application of thermal analyses technique (pyrolysis), thermal and catalytic pyrolysis with nanomaterials, aiming at production petroleum derived. The sludge and vacuum residue were analyzed using a soxhlet extraction system, elemental analysis, thin layer chromatography, thermogravimetry and pyrolysis coupled in gas chromatography/mass spectrometry (Py GC MS). The catalysts AlMCM-41, AlSBA-15.1 e AlSBA-15.2 were synthesized with molar ratio silicon aluminum of 50 (Si/Al = 50), using tetraethylorthosilicante as source of silicon and pseudobuhemita (AlOOH) as source of aluminum. The analyzes of the catalysts indicate that materials showed hexagonal structure and surface area (783,6 m2/g for AlMCM-41, 600 m2/g for AlSBA-15.1, 377 m2/g for AlSBA-15.2). The extracted oily sludge showed a range 65 to 95% for organic components (oil), 5 to 35% for inorganic components (salts and oxides) and compositions different of derivatives. The AlSBA-15 catalysts showed better performance in analyzes for production petroleum derived, 20% increase in production of kerosene and light gas oil. The energy potential of sludge was high and it can be used as fuel in other cargo processed in refinery

Highly Sensitive Neurotransmitters Analysis at Platinum-Ultramicroelectrodes Arrays

An easy way to determine norepinephrine (NE) in biological fluid using a platinum ultramicroelectrode array (Pt-UMEAs) is described. Issues related to UME electrode surface treatment and characterizations are also addressed. At optimized experimental conditions the dynamic concentration range was 1.0 to 10.0 mu mol?L-1 with a detection limit of 40.5 nmol?L-1. The repeatability of current responses for injections of 5 mu mol?L-1 NE was evaluated to be 4.0?% (n=10). This approach obtained excellent sensitivity, a reliable calibration profile and stable electrochemical response for norepinephrine detection. The content of NE in urine samples without any preconcentration, purification, or pretreatment step, was successfully analyzed by the standard addition method using the Pt-UMEAs.

Depressive symptoms in first episode schizophrenia spectrum disorder

Depressive symptoms in 'non-affective' first episode schizophrenia spectrum disorders (FES) are common, but poorly understood, resulting in a range of conceptual and clinical management issues. This study had three aims: (i) to determine the prevalence of moderate to severe depressive symptoms (defined as a Clinical Global Impressions Scale-Bipolar Disorder (CGI-BP depression) score >3) in a large representative sample of FES patients; (ii) to compare the clinical and functional characteristics of FES patients with and without these depressive symptoms at service entry; and (iii) to compare the characteristics of FES patients with and without persistent depressive symptoms.

To research living beings one has to participate in life.' Viktor von Weizsäcker's legacy

Viktor von Weizsäcker has been a German medical doctor and philosopher, well known throughout Europe, but hardly received in the Anglo-American culture. He focusses on the crucial epistemological question how one can conduct research on living beings. The article’s title represents a key quote of his opus magnum “Der Gestaltkreis”, which works out a theory of the unity of perception and motion. According to Viktor von Weizsäcker, one cannot separate the two, meaning that we locate ourselves in a fundamental union with the living world, which has lasting influence on our capacity of perception. This idea does not seem too different from Ian Barbour’s idea about critical realism, exploring a “consciousness of ourselves as arising out of rapport, interconnection and participation in processes reaching beyond ourselves.” Both authors, Viktor von Weizsäcker and Ian Barbour, still have lasting influence on the dialog between religion and science, each in their respective cultures – a further reason to compare their core ideas, after presenting Viktor von Weizsäcker’s life and thought. Finally, the theological impact of von Weizsäcker’s thought will be assessed. Following his philosophy, it becomes clear that the miracle of creation is the condition of the possibility of any perception.

The dicode workbench: A flexible framework for the integration of information and web services

Aiming to address requirements concerning integration of services in the context of ?big data?, this paper presents an innovative approach that (i) ensures a flexible, adaptable and scalable information and computation infrastructure, and (ii) exploits the competences of stakeholders and information workers to meaningfully confront information management issues such as information characterization, classification and interpretation, thus incorporating the underlying collective intelligence. Our approach pays much attention to the issues of usability and ease-of-use, not requiring any particular programming expertise from the end users. We report on a series of technical issues concerning the desired flexibility of the proposed integration framework and we provide related recommendations to developers of such solutions. Evaluation results are also discussed.

O serviço de disponibilização de e-books pelas bibliotecas universitárias: análise do ponto de vista da gestão de operações de serviços.

As bibliotecas universitárias brasileiras procuram oferecer o acesso de livros eletrônicos (e-books) aos usuários, contudo, o uso de e-books está aquém do esperado em bibliotecas, esta situação nos leva ao problema de pesquisa: haveria problemas na produção do serviço de disponibilização de e-books na biblioteca universitária que afetem o uso de e-books nas bibliotecas? Que tipos de problemas podem estar relacionados? Esta pesquisa tem como objetivo analisar a gestão de e-books em bibliotecas universitárias, com o propósito de compreender melhor o uso de e-books na biblioteca e detectar possíveis problemas na produção do serviço. A partir de um estudo de caso de uma rede de bibliotecas de uma universidade pública brasileira e de revisão de literatura, constatou-se que há quatro principais tipos de problemas na gestão de e-books: comerciais, institucionais, organizacionais e conceituais, os quais estão diretamente relacionados com o baixo uso de e-books nas bibliotecas universitárias. A base teórica em gestão de serviços permitiu identificar a relação entre a necessidade de revisão do conceito de serviço de biblioteca acadêmica em conjunto com a solução de questões pontuais de gestão, avançando no entendimento do problema.

Turkey and the Kurdish problem; new approaches in the face of the Middle East crises. Point of View No. 30, February 2013

From the Introduction. For almost a hundred years (since World War I and the disintegration of the Ottoman Empire) stability – or rather, the permanent threat to stability – has been a key challenge for the Middle East. One of the central elements of this threat has been the so-called Kurdish problem, that is, the issues that continually arise between the states of the region and the Kurdish minority living in the area, as well as the tensions among the individual states caused by a range of issues related to local Kurds. The country most affected by the Kurdish problem is Turkey.

The British journal of psychology.

The British Journal of Psychology publishes articles which make major contributions across the range of psychology, particularly where the work has the following characteristics: articles or groups of articles dealing with topics which are of interest to researchers from more than one specialism or section of psychology, or which address topics or issues at the interface between different specialisms or sections of psychology; articles or groups of articles which take different or contrasting methodological or theoretical approaches to a single topic; articles or groups of articles dealing with novel areas, theories or methodologies; integrative reviews, particularly where the review offers new analysis (e.g. meta-analysis), new theory or new implications for practice; articles or groups of articles dealing with the history of psychology; interdisciplinary work, where the contribution from, or to, psychological theory or practice is clear.

Pacific damsel bug: Friend of foe?

Determining the diet of insects present in cotton should be among the first steps in any applied research program. Omnivorous species are particularly important as they have the potential to suppress pest populations through prey feeding, but also to cause economic damage to the crop through plant feeding.
