PUC Campinas / Conselho Nacional de Pesquisa e Desenvolvimento Cient?fico e Tecnol?gico - CNPq / The transition to motherhood is characterized by physical, psychological and social changes, for which the emotional intensity is exacerbated when experienced within the context of exposure to numerous vulnerabilities. The refugee experience denotes the transition to motherhood with all its radicalism, in so far as the pregnancy and motherhood experienced in a foreign country results in numerous disruptions, such as the loss of familial and social support, in addition to being unable to attribute meaning to one?s maternal practices/rituals which will be culturally accepted in the new country. Given this scenario, the objective of this research project was to obtain an understanding of the emotional experience of refugee women throughout their transition to motherhood, by means of the psychoanalytical services provided to two Nigerian women who had just arrived in Brasil and were residing in a social housing institution. The results of this study are presented as psychoanalytical narratives which aims to transport the reader to the experiences lived during the therapeutic sessions. Therapeutic sessions discussed the patients? conditions resulting from escaping Nigeria due to threats posed by the terrorist group Boko Haram; their previous history in their country of origin, including: language, tribal origin and familiar models; the difficulties they encountered experiencing childbirth in a new culture, when the cultural universe of the patients and the Western technological system collide; the challenges of caring for a baby in a culture different from theirs, a culture whose expectations compromise maintaining one?s own maternal rituals and practices, as those practices are interpreted with discrimination and prejudice. The psychoanalytic narratives conclude with the presentation and questioning of the reception offered by the institutional shelter, as well as the clinical services offered in this context of maternity of refugee women. The question of adequate professional qualifications for the care of refugee mothers was discussed in order to assist them with establishing a sufficiently positive mother-infant bond, as well as the task of recovering the ties with the mothers? cultures of origin, which must accompany any professional work in a cross-cultural field. Despite the experience of being a refugee exacerbating maternal challenges, due to the disorganization, confusion and helplessness the situation provokes, it was also possible to observe that motherhood in and of itself can be an experience that rescues women from unthinkable agony and rescues the human character from the experiences they lived through. / A transi??o para a maternidade ? caracterizada por mudan?as f?sicas, psicol?gicas e sociais cuja intensidade afetiva se acentua quando vivida em um contexto em que m?ltiplas vulnerabilidades se sobrep?em. A experi?ncia de ref?gio marca a transi??o para a maternidade com toda a sua radicalidade, na medida em que a gravidez e a maternidade vividas em outro pa?s d? origem a in?meras rupturas, como a perda de suporte familiar e social, al?m da impossibilidade de atribuir um sentido para as suas pr?ticas maternas que seja culturalmente aceito no pa?s de acolhida. Diante desse cen?rio, a presente pesquisa teve como objetivo compreender a experi?ncia emocional de mulheres refugiadas ao longo da transi??o para a maternidade, por meio do atendimento psicanal?tico a duas mulheres nigerianas que tinham acabado de chegar ao nosso pa?s e estavam abrigadas em uma institui??o de alojamento social. Os resultados desta pesquisa s?o apresentados sob a forma de narrativas psicanal?ticas que visam a transportar o leitor para a situa??o vivida nos encontros terap?uticos.

As narrativas psicanal?ticas se encerram com a apresenta??o e questionamento sobre o acolhimento oferecido pela institui??o de abrigamento, bem como sobre o manejo cl?nico proposto nesse contexto da maternidade de mulheres refugiadas. Foram discutidas a quest?o da capacita??o profissional adequada para o cuidado ? m?e refugiada tendo em vista o estabelecimento de uma rela??o m?e-beb? suficientemente boa, al?m da tarefa de resgate dos la?os com a cultura de origem da m?e que deve acompanhar todo trabalho profissional em campo transcultural. Embora a experi?ncia de ref?gio acentue o sofrimento materno, em fun??o da desorganiza??o e desamparo que provoca, tamb?m foi poss?vel observar que a pr?pria maternidade pode se constituir como experi?ncia que resgata a mulher das agonias impens?veis e recupere o car?ter humano das experi?ncias vividas. / La transici?n a la maternidad es caracterizada por cambios f?sicos, psicol?gicos y sociales cuya intensidad afectiva se acent?a cuando se vive en un contexto em el que m?ltiples vulnerabilidades se sobreponen.

Tomando en cuenta este escenario, la presente investigaci?n tuvo como objetivo comprender la experiencia emocional de las mujeres refugiadas durante la transici?n a la maternidad, a trav?s del atendimiento psicoanal?tico de dos mujeres nigerianas que acababan de llegar a nuestro pa?s y se encontraban abrigadas en una instituci?n de ayuda social.

Kaposi's sarcoma-associated herpesvirus (KSHV) expresses numerous intronless mRNAs that are unable to access splicing-dependent cellular mRNA nuclear export pathways. To circumvent this problem, KSHV encodes the open reading frame 57 (ORF57) protein, which orchestrates the formation of an export-competent virus ribonucleoprotein particle comprising the nuclear export complex hTREX, but not the exon-junction complex (EJC). Interestingly, EJCs stimulate mRNA translation, which raises the intriguing question of how intronless KSHV transcripts are efficiently translated. Herein, we show that ORF57 associates with components of the 48S pre-initiation complex and co-sediments with the 40S ribosomal subunits. Strikingly, we observed a direct interaction between ORF57 and PYM, a cellular protein that enhances translation by recruiting the 48S pre-initiation complex to newly exported mRNAs, through an interaction with the EJC. Moreover, detailed biochemical analysis suggests that ORF57 recruits PYM to intronless KSHV mRNA and PYM then facilitates the association of ORF57 and the cellular translation machinery. We, therefore, propose a model whereby ORF57 interacts directly with PYM to enhance translation of intronless KSHV transcripts.

Pseudomonas aeruginosa is a common and important pathogen in people with cystic fibrosis (CF). Recently epidemic strains of P. aeruginosa associated with increased morbidity, have been identified. The method of transmission is not clear, but there is evidence of a potential airborne route. The aim of this study was to determine whether different strains of P. aeruginosa isolated from people with CF were able to survive within artificially generated aerosols in an aerobiological chamber. Viable P. aeruginosa could still be detected up to 45min after halting generation of the aerosols. All of the strains of P. aeruginosa expressing a non-mucoid phenotype isolated from people with CF had a reduced ability to survive within aerosols compared to an environmental strain. Expression of a mucoid phenotype by the strains of P. aeruginosa isolated from people with CF promoted survival in the aerosol model compared to strains expressing a non-mucoid phenotype.

River mouths are very active coastal regions. Continuous sediment supply by the river and the movement by wave action cause the shoreline to change in time and space. Modeling of shoreline changes is an essential step before the design of any coastal engineering project. This research aimed to develop a system of numerical models to present the shoreline changes around a river mouth. The system of numerical models has three components: 1) modeling of nearshore wave characteristics, 2) modeling of longshore sand transport rates using the results of the first component, 3) modeling of shoreline changes using the estimated sand transport rates. Thus, firstly, deep water wave characteristics including the annual wave rose affecting Manavgat River mouth have been obtained from the database of NATO TU-WAVES Project. Then REF/DIF1 and SWAN nearshore wave models have been used to find out nearshore wave conditions. Since the results obtained from REF/DIF1 wave model have been found to be more reasonable compared to SWAN&rsquo / s output, REF/DIF1 wave model has been used in preparing a time series nearshore reference wave file with three hours time interval. This reference file has been used to run GENESIS. Last step of the numerical shoreline change modelling of Manavgat River mouth was the calibration procedure in which the &ldquo / transport parameters&rdquo / k1 and k2 have been determined. As there is lack of measurements of shoreline positions that can be used in calibrating shoreline change model, k1 and k2 has been approximately found to be k1=0.516 and k2=0.9 by using an empirical sediment transport formula. As a future study, it is recommended that when the protection structure controlling the river mouth is finished, the measurements of shoreline position behind the structure should be used in verification of shoreline change model in order to get more accurate results.

Dentre essas fontes, a energia e?lica vem tomando grande destaque. Torna-se importante promover a busca pelo aprimoramento das tecnologias envolvidas nas topologias de aerogeradores, buscando alternativas que aumentem o rendimento obtido, apesar da irregularidade da velocidade do vento. Este trabalho apresenta um novo sistema para controle de velocidade, aqui aplicado em aerogeradores, o Regulador Eletromagn?tico de Frequ?ncia (REF). Um dos dispositivos mais utilizados em algumas topologias s?o as caixas de engrenagens mec?nicas que, al?m de uma vida ?til curta, representam frequentemente, fontes de ru?do e defeitos. O REF dispensa essas caixas de transmiss?o, representando um avan?o tecnol?gico, utilizando para isso uma m?quina de indu??o adaptada, na qual o estator passa a ser m?vel, solid?rio ao eixo da turbina. Na topologia utilizada neste trabalho, o REF tamb?m permite dispensar o uso de conversores eletr?nicos para estabelecer o acoplamento entre o gerador e a rede el?trica, raz?o pela qual tamb?m proporciona a possibilidade de obten??o de gera??o em corrente alternada, com tens?o e frequ?ncia constantes, onde n?o exista a rede el?trica. Respons?vel pelo controle da velocidade mec?nica do gerador, o REF pode ser ?til em outros sistemas de transmiss?o onde o controle de velocidade mec?nica de sa?da seja o objetivo. Al?m disso, por operar atrav?s da combina??o de duas entradas, uma mec?nica e outra el?trica, o REF multiplica as possibilidades de aplica??es por ser apto ao acoplamento sin?rgico entre energias de matrizes diferentes, e, por tais motivos, possibilita que as diversas fontes de energia envolvidas sejam desacopladas da rede, sendo o gerador s?ncrono o respons?vel pela conex?o do sistema com a rede el?trica, simplificando as estrat?gias de controle quanto ? pot?ncia injetada na mesma. Resultados de simula??o e experimentais s?o apresentados no decorrer do trabalho, voltados a um aerogerador, validando a proposta em rela??o a efici?ncia no controle de velocidade do sistema para diferentes condi??es de vento. / The constant necessity for new sources of renewable energy is increasingly promoting the increase of investments in this area. Among other sources, the wind power has been becoming prominent. It is important to promote the search for the improvement of the technologies involved in the topologies of the wind turbines, seeking for alternatives which enhance the gotten performance, despite the irregularity of the wind speed. This study presents a new system for speed control, in this case applied to the wind turbines - the Electromagnetic Frequency Regulator (EFR). One of the most used devices in some topologies is the mechanical gearboxes which, along with a short service life, often represent sources of noise and defects. The EFR does not need these transmission boxes, representing a technological advancement, using for that an adapted induction machine, in which the stator becomes mobile, supportive to the axis of the turbine. In the topology used in this study, the EFR also allows us to leave out the usage of the eletronic converters to establish the coupling between the generator and the electrical grid. It also the reason why it provides the possibility of obtaining the generation in alternating current, with constant voltage and frequency, where there is no electrical grid. Responsable for the mechanical speed control of the generator, the EFR can be useful in other transmission systems in which the mechanical speed control output is the objective. In addition, the EFR operates through the combination of two inputs, a mechanical and other electrical. It multiplies the possibilities of application because it is able to synergistic coupling between different arrays of energy, and, for such reasons, it enables the various sources of energy involved to be uncoupled from the network, being the synchronous generator responsible for the system connection with the electrical grid, simplifying the control strategies on the power injected in it. Experimental and simulation results are presented through this study, about a wind turbine, validating the proposal related to the efficience in the speed control of the system for different wind conditions.

Master's thesis deals with use of electronic instrument transformers (sensors) in the protection system in medium-voltage substation. Substation consists of 2 incoming feeders, 2 outgoing feeders for motors, 2 outgoing feeders for power transformers, measuring, bus coupler and bus riser feeder. Incoming feeders are connected to distribution system E.ON by cable lines which were proposed. Protected machines (power transformers and motors with rated power) are connected to switchgear panels of UniGear ZS1 type by cable lines too. Proposed protection system is based on the short-circuit conditions, standard CSN 33 3051 recommendations as well as theoretical backgrounds acquired from technical papers and other publicated literature according to the bibliography. For selected protection functions are defined their parameters. Control, monitoring and protection functions provides REF 542plus relay. Consequently, secondary tests which are part of the commissioning, are given in the practical part of thesis. Secondary tests were performed by relay test system FREJA 300 by Megger. Results of tests are displayed in tripping characteristics.

Two distinct features of a limited liability company are separate legal existence and consequently limited liability. Those features are also expressed in the principle of limited liability whereby risks are capped by the invested capital. The liability cannot be extended to personal assets. An exception to this principle is made if there has been fraud or other serious wrongdoings. The Swedish Companies Act (2005:551) contains several action-based rules aimed at the company's representatives. Moreover, business companies have freedom of contract based on mutual agreement and free choice. The Swedish Tax Agency, on the other hand, is not operating by the free market rules. Tax liabilities are thus another exception from the principle. Chapter 59 of the Swedish Tax Procedures Act (2011:1244) stipulates that a representative of a company may be liable to pay the amount of tax together with the company, if this person intentionally or through gross negligence fails to pay tax at the right time and in the right way. This separate framework for taxes has been an object of criticism throughout the years, mostly directed at the aspects of legal security and predictability as well as low probability of success in court proceedings against the claims pursued by the state. The Confederation of Swedish Enterprise is driving those issues by lobbying for a revision of the tax liability of representatives. However, the confederation's biased role together with relatively recent development by Supreme Administrative Court ruling warrants an in-depth study of the current regulations. This thesis will investigate and analyze Chapter 59, Section 12-13 and 15 of the Swedish Tax Procedures Act (2011:1244) in administrative courts' application after precedent HFD 2018 ref. 4. This is done by explaining the regulatory framework behind tax liability of representatives, the obligation of a court to follow the law of a superior court, explaining the circumstances in the precedent and lastly by conducting an investigative study of a selection of judgments rendered between years 2018 and 2019. The conclusion shows that current regulations require a balanced view of the situation that proceeded the omission of tax payments when deciding upon personal liability through gross negligence. This was confirmed by Supreme Administrative Court in HFD 2018 ref. 4. Most courts' judgments show an awareness of this fact by either referring to the precedent directly or by describing options available to each representative. Although the liability is not strict, all the studied judgments ended in favor of The Swedish Tax Agency. The precedent is mostly followed by courts, but because of its unusual circumstances, it has limited impact on the outcome of judgments on tax liability. / Utredningen om det skatterättsliga företrädaransvaret (Fi 2019:07)
