Assédio moral na administração pública e a responsabilidade civil do estado

The social and economic changes of the last decades have enhanced the dehumanization of labor relations and the deterioration of the work environment, by the adoption of management models that foster competitiveness and maximum productivity, making it susceptible to the practice of workplace bullying. Also called mobbing, bullying can occur through actions, omissions, gestures, words, writings, always with the intention of attacking the self-esteem of the victim and destroy it psychologically. In the public sector, where relations based on hierarchy prevail, and where the functional stability makes it difficult to punish the aggressor, bullying reaches more serious connotations, with severe consequences to the victim. The Federal Constitution of 1988, by inserting the Human Dignity as a fundamental principle of the Republic, the ruler of the entire legal system, sought the enforcement of fundamental rights, through the protection of honor and image of the individual, and ensuring reparation for moral and material damage resulting from its violation. Therefore, easy to conclude that the practice of moral violence violates fundamental rights of individuals, notably the employee's personality rights. This paper therefore seeked to analyze the phenomenon of bullying in the workplace, with emphasis on the harassment practiced in the public sector as well as the possibility of state liability for harassment committed by its agents. From a theoretical and descriptive methodology, this work intended to study the constitutional, infra and international rules that protect workers against this practice, emphasizing on the fundamental rights violated. With this research, it was found that doctrine and jurisprudence converge to the possibility of state objective liability for damage caused by its agents harassers, not forgetting the possibility of regressive action against the responsible agent, as well as its criminal and administrative accountability.

A nicotina atua como fator deletério na reparação da parede abdominal

Objetivo: Avaliar o efeito da nicotina na cicatrização da camada musculoaponeurótica da parede abdominal. Métodos: Estudo experimental em que foram usados 16 ratos da raça Wistar pesando em média 210±8g, separados aleatoriamente em 2 grupos de 8. Nos animais do grupo A foi implantado disco de nicotina (Nicotinel Ò) na dose de 5mg/Kg de peso/dia no subcutâneo da região dorsal, trocado a cada dois dias, a partir do 5º dia antes da operação em que foi feita laparotomia mediana de 5 cm, até o 10o dia de observação. No grupo B (controle) foram usados discos de celulose com o mesmo diâmetro. Tubo de silicone multiperfurado foi implantado no subcutâneo a 1cm da lesão da parede abdominal. A camada musculoaponeurótica e a pele foram suturadas com fio de nylon 5-0. No 10º dia pós-operatório foi colhido 1ml de líquido seroso do tubo de silicone por punção percutânea para dosagem de pO2 e os animais receberam dose letal de anestésico. Foi ressecado um segmento da camada musculoaponeurótica com 2cm de largura para tensiometria, em seguida processado e corado em HE e tricrômico de Masson para análise quantitativa dos dados histopatológicos em sistema digitalizado. A análise estatística foi feita pelo ANOVA e teste Newman-Keuls, com significância 0,05. Resultados: No grupo A a pO2 do líquido tecidual atingiu o valor 17,75±3,4 mmHg e no grupo B (controle) a pO2 = 40,75±6,4 mmHg (p<0,01). A resistência à tensão apresentou o valor de 728,5±161,75gf no grupo A e 1241,6±232gf no grupo de controle (p<0,01), coincidindo com os achados da pO2. A densidade média dos elementos histopatológicos estudados foi de 105±17,1 nos animais do grupo A e 146,2±8,8 no grupo B (p<0,01). Conclusão: após avaliação da pO2 tecidual, tensiometria e histopatologia, concluiu-se que a nicotina por via subcutânea exerce efeito deletério sobre a cicatrização de lesões da parede abdominal de ratos

Redução de danos e o saber-fazer de profissionais de um CAPS ad em Natal-RN

The present study had as a main objective to analyze how the professionals at a CAPS ad unit in Natal-RN conceive the knowledge-practice process with regard to the Harm Reduction Policy (HRP) towards alcohol and other drugs. For the accomplishment of this proposal, it was intended: 1) Verifying the possibilities and limits of the HRP implementation at a CAPS ad unit in Natal-RN; 2) Relating the professionals knowledge at a CAPS ad unit in Natal in regard to the Harm Reduction Policy; 3) Enumerating the HRP programmatic actions at the institution. The research had exploratory, descriptive and qualitative approach aspects, guided by the concepts of biopower and self care proposed by Michel Foucault. Data collection occurred in June and July 2011, in which the focal group technique was used. After that, collect field material was analyzed through the content analysis method proposed by Minayo. The results showed some conceptual and practical approach between the harm reduction strategy and the knowledge-practice of the professionals at this CAPS ad unit. The discursive models about drug usage, especially the moral-legal model, still have a significant role in the daily lives of these professionals, being amplified by some demands of their jobs or even through the instituted discourse. The individuals recognize the need for less prohibited practices and more socializing ones, identifying them with the Harm Reduction (HR) logic, when there is a coherent and well-founded understanding about HR among the professionals. Distorted and reductionist views about HR as considering the simple instrumental function of this strategy (distribution of basic supplies) among the professionals, represent one of the main barriers for its implementation. There are few programmatic activities that are related to the RD strategy at this CAPS ad unit which makes a more effective appropriation by the working team difficult to reach. The working processes and the postures adopted by this CAP ad unit professionals have been showing that many of their practices and conceptions were modified to the detriment of new necessities emerged from the demands. Consequently, the self care notion is revealed which brings the need for the valorization of these care agents roles, that is, their collective and individual contribution.

Avaliação por pig de perfilagem de danos superfciais nos materiais das paredes de dutos de petróleo

The modern technology of materials and structural integrity of pipelines requests the use of inspection tools named inspection pigs to detect, localize and measure the length, width and depth dimensions of the thickness losses of walls of buried and underwater pipelines in service. These tools run them internally, performing and recording measurements, with performance that varies according to the pig s technology. It has been developed recently an instrumented pig technology, called feller pig. This work aims to indicate factors that influence the feller pig technology performance in the detection and in the accuracy of measurement of the length, width and depth dimensions of the thickness losses on the internal surface of an oil pipeline wall under normal conditions of oil pipe inspection with pig. In this work, is made a collection of factors and an analyses of the technology based on the available literature, as well as an experiment to observe the technology and the factors operating. In the experiment, a feeler pig is used in a pipeline built in carbon steel and in operation that flows petroleum, in witch are observed areas with internal thickness losses occurred naturally. Some of these areas and their dimensions taken by automated ultra-sound scanner are compared with the ones indicated by the feller pig. Based on the data collection, on the analysis and on the experiment, the influence of factors object of this research is discussed. It is concluded that, among these, there are factors related to pipe fabrication tolerances, to wear of pig components, to internal adhesive wear of pipeline, to other pipeline damages and to technology characteristics. Finally, actions are suggested to know better, improve and define the applicability of this technology

Propagação de danos em sistemas cooperativos: propriedades termodinâmicas

High-precision calculations of the correlation functions and order parameters were performed in order to investigate the critical properties of several two-dimensional ferro- magnetic systems: (i) the q-state Potts model; (ii) the Ashkin-Teller isotropic model; (iii) the spin-1 Ising model. We deduced exact relations connecting specific damages (the difference between two microscopic configurations of a model) and the above mentioned thermodynamic quanti- ties which permit its numerical calculation, by computer simulation and using any ergodic dynamics. The results obtained (critical temperature and exponents) reproduced all the known values, with an agreement up to several significant figures; of particular relevance were the estimates along the Baxter critical line (Ashkin-Teller model) where the exponents have a continuous variation. We also showed that this approach is less sensitive to the finite-size effects than the standard Monte-Carlo method. This analysis shows that the present approach produces equal or more accurate results, as compared to the usual Monte Carlo simulation, and can be useful to investigate these models in circumstances for which their behavior is not yet fully understood

Propagação de danos no modelo de ising em redes de bravais e em fractais

In this work we have studied, by Monte Carlo computer simulation, several properties that characterize the damage spreading in the Ising model, defined in Bravais lattices (the square and the triangular lattices) and in the Sierpinski Gasket. First, we investigated the antiferromagnetic model in the triangular lattice with uniform magnetic field, by Glauber dynamics; The chaotic-frozen critical frontier that we obtained coincides , within error bars, with the paramegnetic-ferromagnetic frontier of the static transition. Using heat-bath dynamics, we have studied the ferromagnetic model in the Sierpinski Gasket: We have shown that there are two times that characterize the relaxation of the damage: One of them satisfy the generalized scaling theory proposed by Henley (critical exponent z~A/T for low temperatures). On the other hand, the other time does not obey any of the known scaling theories. Finally, we have used methods of time series analysis to study in Glauber dynamics, the damage in the ferromagnetic Ising model on a square lattice. We have obtained a Hurst exponent with value 0.5 in high temperatures and that grows to 1, close to the temperature TD, that separates the chaotic and the frozen phases

Propagação de danos: importância da atualização dinâmica, efeitos da diluição e propriedades termodinâmicas

Neste trabalho investigamos aspectos da propagação de danos em sistemas cooperativos, descritos por modelos de variáveis discretas (spins), mutuamente interagentes, distribuídas nos sítios de uma rede regular. Os seguintes casos foram examinados: (i) A influência do tipo de atualização (paralela ou sequencial) das configurações microscópicas, durante o processo de simulação computacional de Monte Carlo, no modelo de Ising em uma rede triangular. Observamos que a atualização sequencial produz uma transição de fase dinâmica (Caótica- Congelada) a uma temperatura TD ≈TC (Temperatura de Curie), para acoplamentos ferromagnéticos (TC=3.6409J/Kb) e antiferromagnéticos (TC=0). A atualização paralela, que neste caso é incapaz de diferenciar os dois tipos de acoplamentos, leva a uma transição em TD ≠TC; (ii) Um estudo do modelo de Ising na rede quadrada, com diluição temperada de sítios, mostrou que a técnica de propagação de danos é um eficiente método para o cálculo da fronteira crítica e da dimensão fractal do aglomerado percolante, já que os resultados obtidos (apesar de um esforço computacional relativamente modesto), são comparáveis àqueles resultantes da aplicação de outros métodos analíticos e/ou computacionais de alto empenho; (iii) Finalmente, apresentamos resultados analíticos que mostram como certas combinações especiais de danos podem ser utilizadas para o cálculo de grandezas termodinâmicas (parâmetros de ordem, funções de correlação e susceptibilidades) do modelo Nα x Nβ, o qual contém como casos particulares alguns dos modelos mais estudados em Mecânica Estatística (Ising, Potts, Ashkin Teller e Cúbico)

Associação entre polimorfismos em enzimas de reparo de DNA e ocorrência de meningite bacteriana.

Despite advances in vaccine development and therapy, bacterial meningitis (BM) remains a major cause of death and long-term neurological disabilities. As part of the host inflammatory response to the invading pathogen, factors such as reactive oxygen species are generated, which may damage DNA and trigger the overactivation of DNA repair mechanisms. It is conceivable that the individual susceptibility and outcome of BM may be in part determined by non synonymous polymorphisms that may alter the function of crucial BER DNA repair enzymes as PARP-1, OGG-1 and APE-1. These enzymes, in addition to their important DNA repair function, also perform role of inflammatory regulators. In this work was investigated the non synonymous SNPs APE-1 Asn148Glu, OGG-1 Ser326Cys,PARP-1 Val762Ala, PARP-1 Pro882Leu and PARP-1 Cys908Tyr in patients with bacterial meningitis (BM), chronic meningitis (CM), aseptic meningitis (AM) and not infected (controls). As results we found increased frequency of variant alleles of PARP-1 Val762Ala (P = 0.005) and APE-1 Asn148Glu (P=0.018) in BM patients, APE-1 Asn148Glu in AM patients (P = 0.012) and decrease in the frequency of the variant allele OGG-1 Ser326Cys in patients with CM (P = 0.013), regarding the allelic frequencies in the controls. A major incidence of individuals heterozygous and/ or polymorphic homozygous in BM for PARP-1 Val762Ala (P= 0.0399, OD 4.2, 95% IC 1.213 -14.545) and PARP-1 Val762Ala/ APE-1 Asn148Glu (P = 0.0238, OD 11.111, 95% IC 1.274 - 96.914) was observed related to what was expected in a not infected population. It was also observed a major incidence of combined SNPs in the BM patients compared with the control group (P=0.0281), giving evidences that SNPs can cause some susceptibility to the disease. This combined effect of SNPs seems to regulate the principal cytokines and other factors related to BM inflammatory response and point the importance of DNA repair not only to repair activity when DNA is damaged, but to others essential functions to human organism balance.

A redução de danos no atendimento especializado em álcool e outras drogas

The harm reduction HR is the official policy of Ministry of Public Health to deal with problem derived from alcohol consumption and other drugs AD. The HR refers to policies and support programs whose purpose is to reduce the risks related to the use of AD, without necessarily decrease individual consumption. This research aim was to analyze the HR conceptions and practices at two specialized institutions for AD users: 1) Psychosocial Care Center Alcohol and Drugs III (CAPSad III); 2) Therapeutic Community Fazenda da Esperança (FE) Dom Bosco. This is a qualitative research that used the following methodological tools: semi-structured interview with 21 professionals; socio demographic file and rounds of conversation with 63 participants users; participant observation and field journal. The interviews with professionals have characterized HR as a less complex and cheap treatment. At FE the HR proposal does not make part of their actions, being considered ―against the human being dignity‖. At CAPSad III is understood as an ―inevitable‖ guideline to service, once users do not remain abstinent. The users understand RD as an improvement in healthy conditions, social relations and work that occurs with the decreasing consumption of AD. They use the HR when they avoid situations that facilitate AD consumption, share relapse prevention strategies and, exclusively at CAPSad III, decrease psychotropic consumption. Stands out as an analyzer the HR comprehension as a less efficient treatment that opposes to the objective of both institutions, which is abstinence. The HR is not operationalize in daily routine by professionals and users as a healthy promotion strategy, however, the users are more affected to HR and produce strategies to face the difficulties arising from the AD consumption

Análise experimental de danos em pistões de motor à gasolina operando com adição de gás hidróxi

The addition of hydrogen gas as an alternative fuel source has been widely used, as well reported in scientific literature. Today, several experiments are underway for the use of hydrogen generators (electrolysers) demand for motor vehicles. In all these products their ads manufacturers claim that this provides a reduction of fuel consumption, reduces the emission levels of toxic gas by the discharge and improves engine life. This research analyzes the physical structure of engine components using electrolysis on demand. To this end, a stationary system was fitted with a power generator of electricity, drum roller and adapted two electrolyzers: a dry cell and wet cell other. In steps observation were consumption analyzes in four work load ranges and observing the piston engine, which has been cut and analyzed by Optical Microscopy (OM), Scanning Electron Microscopy and Dispersive Energy (SEM-EDS), X – Ray Diffraction (XRD) and Confocal Microscopy, the stationary system in each step. The results showed a considerable reduction in fuel consumption and a high corrosion in the original factory piston constituted of aluminum-silicon alloy. As corrosion barrier was made a plasma nitriding in the piston head, which proved resistant to attack by hydrogen, although it has presented evidence also, of having been attacked. It is concluded that the automotive electrolysers can be a good choice in terms of consumption and reducing toxic gas emissions, but the material of the combustion chambers of vehicles must be prepared for this purpose.
