The Republic of Serbia stands for the prohibitionist model of regulating prostitution. According to Article 16 paragraph 1 of the Law on Public Order and Peace of the Republic of Serbia, a person who deals with prostitution will be subject to the fine for a misdemeanor. Apart from the fact that prostitution is misdemeanor against public order and peace persons who are dealing with the prostitution, who are mostly women, will be exposed to the condemnation of society. Condemnation of the society is connected with stigmatization, marginalization and discrimination of women in prostitution.<br />Unproportionally large number of women dealing with the prostitution comparing to the number of men was determinative to establish the Ph.D. thesis on the theoretical concept of gender, the primary analytical category in feminist researches, accepting the fundamental concept that &ldquo;gender regimes are not simply the relationship between men and women, but are the system of power, expectations, roles, behaviors, attitudes, discourse and presentation, visualization and hierarchization of gender difference&rdquo; (Blagojevic Hughson 2013, 34). The gender approach, which on one hand, &ldquo;is limiting individual abilities and freedoms&rdquo; (ibid), is on the other hand opening the path of women towards prostitution, while the society most often wrongly sees prostitution as a woman&rsquo;s &ldquo;choice&rdquo;. In accordance with this, we analyze prostitution as a woman&rsquo;s profession taking into consideration that gender pattern shaped by patriarchal ideology in Serbia, in certain unfavorable life circumstances hasinvisible but powerful pressure on a woman to enter into prostitution.<br />The basic goal of the research is to, taking into consideration the accepted prohibitionist approach in regulating prostitution, analyze the legal and social status of women in prostitution.<br />Apart from the current legal and social status of women in prostitution in Serbia, based on the historical-legal method we have analyzed the status of women in prostitution in Serbia in the time period from before the First World War up today.<br />In order to critically review all the aspects of the current prohibitionist model in Serbia, the thesis analyzes in addition to the prohibitionist, also the reglementary, abolitionist and neo-abolitionist model. Two countries were selected,which accepted one of the stated models and we analyzed the impact of the selected model on the status of women in prostitution.<br />The legislation of the Federal Republic of Germany and the Kingdom of the Netherlands was chosen for the analysis in order to assess how the reglementary model influences the status of women in prostitution. The legislation of the Italian Republic and Kingdom of Spain was selected from the countries that implemented the abolitionist model. In order to have insight into a relatively new, a neo-abolitionist model of regulating prostitution we chose to analyze the legislation of the Kingdom of Sweden and the Kingdom of Norway. The legislation of the Republic of Croatia and Montenegro were selected, which like the Republic of Serbia, accept the prohibitionist model.<br />Since in this PhD thesis we strive to present the full picture of legal status of women in prostitution in the Republic of Serbia, we conducted empirical research and the results of this research enabled us to have insight into the practice of authorities in charge for processing the cases of prostitution and to have more clear picture about the social status of women in prostitution in the Republic of Serbia.<br />Based on the results of conducted research, we came to the conclusion that it is necessary to change the legal status of women in prostitution. This change is possible only by abandoning the existing prohibitionist approach in regulating prostitution that negatively affects all the aspects of women&rsquo;s lives in prostitution.<br />In accordance with the results of the research, in the Ph.D. thesis we gave recommendations for improvement of the legal and social status of women in the prostitution in the Republic of Serbia.</p> / null

Today, it is natural to reuse third-party services to compose new services. This process of composition can occur in two styles, called orchestration and choreography. A choreography represents a collaboration between services which know their partners in the composition, to achieve the service s desired functionality. On the other hand, an orchestration have a central process (the orchestrator) that coordinates all application operations. Our work is placed in this latter context, by proposing an abstract model for running service orchestrations. For this purpose, a graph reduction machine will be defined for the implementation of service orchestrations specified in a variant of the PEWS composition language.

The starting materials were used for deposition of tantalum oxide powder and aluminium. These two materials were mixed and ground into high-energy mill, then immersed in the torch for the production of alumina coating infused with particles of tantalum with nano and micrometric size. The spraying equipment used is a plasma torch arc not transferred, which operating in the range of 250 A and 80 V, was able to produce enough heat to ignite aluminothermic between Ta2O5 and aluminum. Upon reaching the plasma jet, the mixing powders react with the heat of the blaze, which provides sufficient energy for melting aluminum particles. This energy is transferred through mechanisms of self-propagating to the oxide, beginning a reduction reaction, which then hits on the surface of the substrate and forms a coating on which a composite is formed by a junction metal - ceramic (Ta +Al2O3). The phases and quantification of each were obtained respectively by X-ray diffraction and the Rietveld method. Morphology by scanning electron microscopy and chemical analysis by energy dispersive spectroscopy EDS. It was also performed measurements of the substrate roughness, Vickers microhardness measurements in sprays and determination of the electron temperature of the plasma jet by optical emission spectroscopy EEO. The results confirmed the expectation generated around the end product of spraying the mixture Ta2O5 + Al, both in the formation of nano-sized particles and in their final form. The electron excitation temperature was consistent with the purpose of work, in addition, the thermodynamic temperature was efficient for the reduction process of Ta2O5. The electron excitation temperature showed values of 3000, 4500 and 8000 K for flows10, 20 and 30 l / min respectively, these values were taken at the nozzle exit of the plasma jet. The thermodynamic temperature around 1200 ? C, was effective in the reduction process of Ta2O5 / Substratos met?licos de a?o inox 416 foram revestidos por aspers?o t?rmica em tocha de plasma.

The flame temperature was characterized by optical emission spectroscopy, through Boltzmann-plot-method. The torch has been used like igniter in the aluminothermic reduction of the mixture tantalum oxide and aluminum, seeking to obtain metallic tantalum. In heating of the reagents only one particle will be considered to study interactions between plasma-particle, seeking to determinate its fusion and residence time. The early powders were characterized by laser granulometry, scanning electron microscopy (SEM) and X-ray diffraction analysis. The final product of this reaction was characterized by SEM and X-ray diffraction. Crystallite size was calculated by the Scherrer equation and microdeformation was determined using Willamsom-Hall graph. With Rietveld method was possible to quantify the percentile in weight of the products obtained in the aluminothermic reaction. Semi-quantitative chemical analysis (EDS) confirmed the presence of metallic tantalum and Al2O3 as products of the reduction.

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. / O presente estudo teve como objetivo geral analisar como os profissionais de um CAPS ad do munic?pio de Natal-RN concebem o saber-fazer no que se refere ? Pol?tica de Redu??o de Danos (PRD) em ?lcool e outras drogas. Para o seu alcance, pretendeu-se: 1) Verificar as possibilidades e limites da implementa??o da PRD em um CAPS ad do munic?pio de Natal-RN; 2) Relacionar o conhecimento dos profissionais de um CAPS ad de Natal quanto ? Pol?tica de Redu??o de Danos; 3) Enumerar as a??es program?ticas ? PRD na referida institui??o. A pesquisa configurou-se como explorat?ria, descritiva e de abordagem qualitativa, norteada pelos conceitos de biopoder e do cuidado de si, propostos por Michel Foucault. A coleta dos dados foi realizada entre os meses de junho e julho de 2011, empregando-se a t?cnica do grupo focal. Em seguida, o material recolhido em campo foi analisado, utilizando-se como m?todo a an?lise de conte?do de Minayo. Os resultados evidenciaram uma aproxima??o conceitual e pr?tica entre a estrat?gia da redu??o de danos e o saber-fazer dos profissionais do CAPS ad. Os modelos discursivos acerca do uso de drogas, com destaque para o modelo jur?dico-moral, ainda possuem espa?o significativo no cotidiano desses profissionais sendo amplificado pela natureza de algumas demandas que chegam at? esses ou pelo pr?prio discurso institu?do. Os sujeitos reconhecem a necessidade de pr?ticas menos proibitivas e mais socializadoras, identificando-as com a l?gica da Redu??o de Danos (RD), quando ? sendo percept?vel uma compreens?o coerente e fundamentada pela maioria dos profissionais acerca da RD. Vis?es distorcidas e reducionistas acerca da RD pelos profissionais, como considerar apenas a fun??o instrumentalizadora dessa estrat?gia (distribui??o de insumos), configuram-se como uma das maiores barreiras a sua implementa??o. H? um n?mero reduzido de atividades program?ticas no interior desse CAPS ad, que guardam rela??o com a estrat?gia da RD, o que dificulta uma apropria??o mais efetiva por parte da equipe de trabalho. Os processos de trabalho e as posturas adotadas pelos profissionais do CAPS ad nos ?ltimos tempos demonstram que muitas de suas pr?ticas e concep??es foram modificadas em detrimento das novas necessidades que as demandas atendidas lhes trouxeram. Por consequ?ncia, a no??o do cuidado de si descortina-se, fazendo-se necess?ria a valoriza??o do papel desempenhado por esses agentes do cuidado, ou seja, a sua contribui??o individual e coletiva.

During these processes, particles are retained due to mechanisms like size exclusion (straining), adsorption, sedimentation and diffusion. In this thesis, a mathematical model is proposed and analytical solutions are obtained. The obtained analytic solutions for the proposed model, which takes pore and particle size distributions into account, were applied to predict the particle retention, pore blocking and permeability reduction during dead-end microfiltration in membranes. Various scenarios, considering different particle and pore size distributions were studied. The obtained results showed that pore blocking and permeability reduction are highly influenced by the initial pore and particle size distributions. This feature was observed even when different initial pore and particle size distributions with the same average pore size and injected particle size were considered. Finally, a mathematical model for predicting equivalent permeability in porous media during particle retention (and pore blocking) is proposed and the obtained solutions were applied to study permeability decline in different scenarios / A modelagem do transporte de suspens?es em meios porosos ? essencial para o entendimento de diversos processos de interesse industrial e cient?fico.

Neste trabalho, um modelo matem?tico para o mecanismo de exclus?o pelo tamanho foi proposto e solu??es anal?ticas foram encontradas. As solu??es anal?ticas para o modelo proposto, que incorpora as distribui??es de tamanho de poros e de part?culas, foram utilizadas para prever a reten??o de part?culas, o bloqueio de poros e a redu??o de permeabilidade durante a microfiltra??o direta (dead-end microfiltration) em membranas. Foram analisados diversos cen?rios, considerando diferentes distribui??es de tamanho de poros e de part?culas. Os resultados obtidos mostraram que o processo de bloqueio de poros e redu??o de permeabilidade ? fortemente influenciado pelas distribui??es iniciais de tamanho de poros e de part?culas. Esta caracter?stica foi observada mesmo quando diferentes distribui??es iniciais de tamanho de poros e de part?culas com um mesmo tamanho m?dio de part?culas e de poros foi considerado. Finalmente, um modelo matem?tico para a previs?o da permeabilidade equivalente em meios porosos durante a reten??o de part?culas (e bloqueio de poros) foi proposto e as solu??es obtidas foram aplicadas para o estudo do decl?nio da permeabilidade em diferentes cen?rios / 2020-01-01

This study will look for, also based in an economical analysis, the juridical legitimity of choosing natural gas as the new protagonist of national economic growth (as a substitute of petroleum) and the necessary boost that must be done by law, based on an economic policy focused strictly for that fact, as a modifying agent of this reality. This study, therefore, will always be turned to a constitutional aspect, respecting the principles of economic order and the goal of reducing regional inequalities, which must influence the making off of a developing plan. At the end, it will try to demonstrate the juridical viability of such undertaking, tuned in jus-economical criteria. Another goal is related to the analysis of the natural gas industry, due the regulation of its transport has a major importance for national energetic integration, not only because this activity be characterized as a net industry, still under control of a natural monopoly, but also because the competitive or cooperative profile that should be priorized at the beginning of the economic planning for this activity (such as investment policies and its own rules that will submit private agents) / Em um pa?s de dimens?es continentais como o Brasil, tem-se como um dos principais desafios para o seu crescimento econ?mico a quest?o log?stica relativa ? capacidade de suprimento de demanda energ?tica. Vive-se atualmente a era da defesa do meio ambiente e, neste novo contexto de prioriza??es, passa-se pela busca da substitui??o da matriz energ?tica, seja pela necessidade decorrente dos altos custos do petr?leo no plano internacional (e da finitude das reservas), como tamb?m pelo grave desgaste ecol?gico por ele gerado. Essa tentativa de substitui??o precisa de solu??es focadas na realidade nacional, num plano estrat?gico de desenvolvimento a longo prazo e na an?lise da viabilidade jur?dico-econ?mica da sua realiza??o. Buscar-se-?, neste estudo, sem descurar de uma an?lise econ?mica de fundo, verificar a legitimidade jur?dica da op??o pelo g?s natural como novo protagonista do desenvolvimento nacional (em substitui??o ao petr?leo) e a necess?ria indu??o a ser exercida pelo direito, via uma pol?tica econ?mica voltada estritamente para tal fato, como agente modificador dessa realidade. O estudo, portanto, estar? voltado sempre no plano constitucional, subordinado aos princ?pios da ordem Econ?mica e da busca pela redu??o das desigualdades regionais, que devem permear a elabora??o do plano de desenvolvimento. Procurar-se-? demonstrar, ao final, a viabilidade jur?dica do empreendimento, sintonizada em crit?rios jus-econ?micos, e tamb?m que, na ind?stria do g?s natural, a regula??o do seu setor de transporte exerce import?ncia crucial para a integra??o energ?tica nacional, n?o apenas por se tratar tal atividade de uma ind?stria de rede, ainda sujeita ao monop?lio natural de uma ?nica empresa, mas tamb?m pelo perfil competitivo ou cooperativo a ser priorizado quando se for desenvolver o planejamento econ?mico do setor (tanto a pol?tica de investimentos, quanto ?s pr?prias regras que submeter?o os agentes econ?micos privados)

This deep change in the legal regime of oil sector brought the possibility of entrance to small and medium size producers in this industry, especially through the production activities developed in mature and marginal fields of oil, which are located mainly in northeast region of Brazil. Considering that the intervention of state over the economy finds its guidelines and limits in Federal Constitution disposals, the present work investigated in which way states regulation, mainly through taxation rules, has obeyed the constitutional regime in force, and specially, the reduction of regional inequalities principle. By mean, firstly, of an analysis of central concepts (mature fields, marginal fields, small and medium size producers) we observed that the imprecision over the conceptual aspect has constituted an obstacle to a specific states&#8223; regulation, directed to this newborn class of producers, whose growth has been pursuit by the state. That is verified in the case of concession procedures, and also, concerning the taxation system applied to small and medium size producers. Examining the main constitutional principles related to this universe which are the legality, equality, privileged treatment to small enterprises, contributive capacity, and reduction of regional inequalities we conclude that it is legally possible, a truly specific regulation, including a special taxation regime, to the small and medium size producers whose activities are concentrate over mature-marginal fields, aiming the concretization of the Brazilian state main goals / No contexto de desestatiza??o que permeou a economia brasileira na d?cada de 1990, surgiu a Emenda Constitucional 9/95, que deu contornos mais flex?veis ao monop?lio da Uni?o sobre o petr?leo. Tal modifica??o no regime jur?dico do setor petrol?fero trouxe a possibilidade de inser??o de pequenos e m?dios produtores, sobretudo no ?mbito da produ??o em campos maduros e marginais de petr?leo, os quais se situam majoritariamente na regi?o Nordeste. Considerando que a interven??o do Estado sobre o dom?nio econ?mico encontra diretrizes e limites postos pela Constitui??o Federal, o presente trabalho investiga de que forma a atividade regulat?ria do Estado, principalmente por interm?dio de normas tribut?rias, tem se conformado ao regime constitucional vigente e, em especial, ao princ?pio da redu??o das desigualdades regionais. Por meio, primeiramente, da an?lise dos conceitos centrais envolvidos (campos maduros, campos marginais, pequenos e m?dios produtores) observou-se que a imprecis?o que circunda o aspecto conceitual tem constitu?do entrave a uma regula??o estatal espec?fica para esta nascente classe de produtores, cujo est?mulo tem sido propugnado pelo Estado em diversos ?mbitos normativos. Tal se verifica tanto no caso dos procedimentos de concess?o quanto no tratamento tribut?rio que vem sendo conferido aos pequenos e m?dios produtores do setor. Por meio do exame dos principais princ?pios constitucionais pertinentes ao tema da legalidade, da igualdade, do tratamento favorecido a empresas de pequeno porte, capacidade contributiva e redu??o das desigualdades regionais , constata-se que ? juridicamente poss?vel uma regula??o verdadeiramente diferenciada, incluindo-se um regime tribut?rio espec?fico, para a atividade dos pequenos e m?dios produtores sobre os campos maduro-marginais, com o fito de concretizar os fins prec?puos do Estado brasileiro

In addition to analyzing these parameters is also made a study of the mutual coupling between the elements of the array. To accomplish this study, were designed a microstrip antenna array with two patch elements, fed by a network feed. Another change made in the array was the use of the truncated ground plane, with the objective of increasing the bandwidth and miniaturize the elements of the array. In order to study the behavior of frequency selective surfaces applied in antenna arrays, three different layouts were proposed. The first layout uses the FSS as a superstrate (above the array). The second layout uses the FSS as reflector element (below the array). The third layout is placed between two FSS. Numerical and experimental results for each of the proposed configurations are presented in order to validate the research / Este trabalho tem como objetivo apresentar como a aplica??o de superf?cies seletivas em frequ?ncia (FSS) em arranjos de antenas planares se torna uma alternativa interessante para se obter caracter?sticas de radia??o desejadas, a partir de altera??es em par?metros de radia??o dos arranjos, tais como largura de banda, ganho e diretividade. Al?m de analisar esses par?metros, tamb?m ? feito o estudo do acoplamento m?tuo entre os elementos do arranjo. Para realizar tal estudo, foi projetado um arranjo de antenas de microfita, com dois elementos do tipo patch, alimentado por uma rede de alimenta??o. Outra modifica??o feita no arranjo foi a utiliza??o do plano de terra truncado, com o objetivo de aumentar a largura de banda e miniaturizar os elementos do arranjo. Para poder estudar o comportamento das superf?cies seletivas em frequ?ncia aplicadas em arranjos de antenas, foram propostos tr?s layouts diferentes. O primeiro layout consiste em utilizar a FSS como superstrato (acima do arranjo). O segundo consiste em utilizar a FSS como elemento refletor (abaixo do arranjo). O terceiro layout consiste em colocar o arranjo entre duas camadas de FSS, tanto em cima quanto abaixo. Resultados num?ricos e experimentais para cada uma das configura??es propostas s?o apresentados

The experimental procedure was carried out in a bench scale flotation unit. The influences on the pre-treatment conditions (coagulant dosage and flocculation time) and flotation parameters (superficial application rate and recirculation rate) were evaluated considering the efficiency of the process. The efficiency was evaluated by determining the turbidity of the untreated and treated water samples. The results obtained showed that turbidity reduction can be obtained very efficiently by using DAF and the latter coagulant in low turbidity water. Using aluminum sulphate in pH?s 5.0 and 6.0 better efficiencies were obtained with low concentrations (15 mg/L), achieving values of 92% of turbidity reduction. In the case of use of Moringa oleifera better efficiencies of reduction of turbidity were reported when using a concentration of 50 mg/L in all range of pH?s, achieving 86% of reduction. The zeta potential was also determined, in an attempt to aid comprehension of the coagulation mechanisms involved. The coagulation mechanisms with Moringa oleifera seeds were shown to be adsorption and charge neutralization, as well as adsorption and bridging. Concerning aluminum sulphate, the predominant mechanisms are adsorption and charge neutralization and enmeshment in a precipitate. The results indicate that for low turbidity water, Moringa oleifera seeds could potentially be a viable substitute for aluminum sulphate / O presente trabalho tem como objetivo investigar o processo da flota??o por ar dissolvido sob press?o - FAD para clarifica??o de ?guas com baixa turbidez utilizando sulfato de alum?nio e sementes de Moringa oleifera como coagulantes. O procedimento experimental foi realizado em uma unidade de flota??o em escala de bancada. Foram avaliadas as influ?ncias das condi??es do pr?-tratamento (dosagem de coagulante e tempo de flocula??o) e par?metros de processo da flota??o (taxa de aplica??o superficial e taxa de recircula??o) na efici?ncia do processo. A efici?ncia foi avaliada pela determina??o de turbidez nas amostras de ?gua bruta e tratada. Os resultados obtidos mostraram que elevadas efici?ncias de redu??o da turbidez podem ser conseguidas com o uso da FAD em ?guas com baixa turbidez utilizando estes coagulantes. Para o sulfato de alum?nio, nos pHs 5,0 e 6,0 as melhores efici?ncias foram alcan?adas com baixas dosagens (15 mg/L), alcan?ando valores de at? 92% de redu??o. Para a Moringa oleifera, as melhores efici?ncias de redu??o de turbidez foram ? dosagem aproximada de 50 mg/L para todos os pHs, alcan?ando valores de 86% de redu??o. Determinou-se tamb?m o potencial zeta, com o objetivo de auxiliar na compreens?o dos mecanismos envolvidos na coagula??o. Os mecanismos de coagula??o com sementes de Moringa oleifera indicam ser adsor??o e neutraliza??o de cargas e adsor??o e forma??o de pontes. No que diz respeito ao sulfato de alum?nio os mecanismos predominantes s?o adsor??o e neutraliza??o de cargas e varredura. Os resultados indicam que para ?guas de baixa turbidez, as sementes de Moringa oleifera podem ser um substituto potencialmente vi?vel em rela??o ao sulfato de alum?nio
