This paper tries to define the concept of Export Finance and establish if the Export Financing is cost-effective way to raise capital and how is it organized in the Russian Federation. In order to do so, several methods have been used: the related literature has been studied, numerical analysis of economic-efficience of export financing has been prepared based on the real example and three interviews with experts in Export Finance have been conducted. The findings suggests that Export Financing is an attractive way of financing in a current economic environment and there is no credible alternative to it on the Russian market. Moreover, the analysis show that despite of the number of advantages, that Export Financing have, there are still some gaps in Export Financing, but in general, Export Finance area is developing and becoming more and more popular among russian importers and exporters

The aims of this research project were to identify and classify the binder-filler interfaces formed in carbon electrodes and to determine the effects of the interfacial quality on important electrode properties. The effects of raw materials and some fabrication process variables on interfacial characteristics and quality of laboratory produced test electrodes were also studied, and the development of binder-filler interfaces during the carbonisation process followed. Electrode quality was assessed by measurement of density, electrical resistivity and tensile strength. Pore structural data were also obtained by using a computerised image analysis system allied to an optical microscope. Interface quality data were obtained by examining etched surfaces in a scanning electron microscope and classifying the binder-filler interface observed into one of five categories. The category depending on the extent of contact between the binder and filler. Accordingly, test electrodes were produced from combinations of four filler carbons, comprising three grades of calcined petroleum coke and an electro-calcined anthracite, and four coal-tar binder pitches which varied in the type and quantity of insoluble matter content. Examination of these test electrodes showed that the nature of the filler carbon used had a dominant influence on the quality of the interface formed, as assessed by this technique. A combination of one filler carbon and one binder pitch was used to study the effects of some fabrication process variables. These were pitch content and, mixing time and temperature. Of these process variables, pitch content and mixing temperature were found to have the major effects on the binder-filler interface and electrode quality. Investigation of the development of the binder-filler interfaces during the carbonisation process showed three distinct zones of interface development and transformation. These zones were associated with three temperature dependent mechanisms; thermal stress relaxation between 200-350 degrees C, volatile gas evolution from coal-tar pitch decompositionb etween3 50-600 degrees C and stresses induced by thermal contraction of the binder phase between 600-1000 degrees C.

Inhibition of angiotensin converting enzyme (ACE) has been identified as a therapeutic target for controlling high blood pressure because the octapeptide angiotensin II, which has vasoconstrictor activity, have minimized their activity in blood vessels. Compounds found in the bark of cashew nuts were separated and identified, and their potential for ACE inhibition was studied. It was observed that the anacardic acids possess this activity, being the 3-anacardic acid inhibitor best among the largest phenolic compounds extracted from the bark of cashews. In silico studies are currently performed to predict the bioavailability and the ability to penetrate the central nervous system (CNS) of a drug. We attempted to conduct this study to verify these properties in anacardic acids, as well as compare with other ACE inhibitors. It was observed that the anacardic acids infringe only one of the five rules of Lipinski, and as the rule states that at least three of these requirements must be satisfied, it is concluded that the anacardic acids exhibit good oral bioavailability and CNS penetration. Thus, the search for a cashew that provides a greater mass of LCC per extraction well as a greater amount of anacardic acid per kilogram of LCC becomes important. From this, it was found among five crops of dwarf cashew (CCP-76, CCP- 09, Embrapa-110, Embrapa-119 and Embrapa-109) which could offer a LCC with greater amount of anacardic acids. The cashew labeled CCP-76 gave a higher amount of LCC to about 30 grams per 50 grams of chestnut bark used for extraction and obtained a concentration of 185 grams per kilogram of anacardic acids LCC to be the best extraction of alkylphenols, among studied. In parallel to these studies, we sought to investigate differences existing compounds in Jatropha mollissima grown in different regions, and it was found that the stress of Ceará hinterlands increases the synthesis of substances for their survival. Thus, these plants can be used in preventive medicine, however, further study should be conducted. / A hipertensão arterial é uma doença que afeta milhões de pessoas em todo o mundo e dentre seus principais fatores causadores destacam-se uma dieta pouco saudável, falta de exercícios físicos e obesidade. A inibição da enzima conversora da angiotensina (ECA) foi identificada como um alvo terapêutico para controlar a pressão arterial elevada, pois o octapeptídeo angiotensina II, que possui atividade vasoconstritora, terá sua atividade minimizada nos vasos sanguíneos. Compostos encontrados na casca da castanha de caju foram separados e identificados e seu potencial de inibição da ECA foi estudado. Observou-se que os ácidos anacárdicos possuem essa atividade, sendo o ácido 3-anacárdico o maior inibidor entre os compostos fenólicos extraídos da casca da castanha de caju. Estudos in silico são realizados atualmente para predizer a biodisponibilidade oral e a capacidade de penetração no sistema nervoso central (SNC) de uma droga. Buscou-se realizar este estudo para verificar essas propriedades nos ácidos anacárdico, assim como também, comparar com outros inibidores da ECA. Observou-se que os ácidos anacárdicos violam somente uma das cinco regras de Lipinski, e como a regra estabelece que pelo menos três destes requisitos devam ser satisfeitos, conclui-se que os ácidos anacárdicos apresentam uma boa biodisponibilidade oral e penetração no SNC. Desse modo, a busca por uma espécie de clone que forneça uma maior massa de LCC por extração assim como uma maior quantidade de ácidos anacárdicos por quilograma de LCC se torna importante. A partir disso, verificou-se entre cinco cultivos de cajueiros anões (CCP-76, CCP-09, Embrapa-110, Embrapa-119 e Embrapa-109) o que poderia oferecer um LCC com maior quantidade de ácidos anacárdicos. O cajueiro identificado como CCP-76 forneceu uma maior quantidade de LCC com cerca de 30 gramas para cada 50 gramas de casca de castanha utilizada para extração e se obteve uma concentração de 185 gramas de ácidos anacárdico por quilograma de LCC, sendo o melhor para extração dos alquilfenóis, entre os estudados. Em paralelo a esses estudos, procurou-se verificar a diferença de compostos existentes na raiz de Jatropha mollissima cultivada em regiões diferentes e verificou-se que o estresse do sertão cearense aumenta a síntese de substâncias para a sua sobrevivência, sendo a raiz a região da planta escolhida por ser rica em metabolitos secundários. Assim, essas plantas podem ser utilizadas na medicina preventiva, porém, estudos mais profundos devem ser realizados.

Conduzimos a investigação com base em duas grandes questões: 1) Como este adolescente, duplamente excluído, por abandono e deficiência, interpretou sua situação de vida e como suas percepções foram incorporadas; 2) e sobre sua história de vida e expectativa de vida adulta, as quais foram: trabalho, profissionalização, relacionamentos afetivos e sexualidade. Tivemos, como objetivo geral, resgatar a história de vida de um adolescente, acolhido em uma unidade de abrigo institucional e, como objetivos específicos, resgatar a sua história de vida do ponto de vista de suas narrativas: sobre a sua escolarização, modalidade de ensino e trajetória e analisar sua percepção sobre o seu processo de escolarização. Trata-se de uma pesquisa qualitativa tendo por base o método História de Vida. Para a coleta de dados, utilizamos entrevista aberta, contendo temas que possibilitaram conhecer a trajetória de vida do adolescente em estudo. A narrativa do sujeito permitiu construir quatro temas: 1 – História de família: marcas das saudades; 2 – História do abrigo: marcas da exclusão; 3 – História da escolaridade: inclusão, afinal? 4 – História de perspectiva de futuro e transição para a vida adulta. Perspectivas inclusivas? O estudo revelou que o adolescente, como qualquer outro de sua idade, possui sonhos e perspectivas de futuro, os quais, mediante sua história de vida e a realidade em que se encontra no abrigo institucional, provavelmente, terá dificuldades de concretizar. Conforme Sávio (nome fictício), sua escolarização é complexa e não consegue acompanhar o processo de ensino e aprendizagem dos demais alunos do ensino regular. O Estatuto da Criança e do Adolescente prevê uma legislação eficiente que proporciona viabilidade de uma práxis transformadora de inserção social e de superação da exclusão social. No entanto, nos deparamos com esta pesquisa, que sugere à unidade de acolhimento necessidade de mudanças reais em seus paradigmas e (re) significações de seu espaço institucional para que crianças e adolescentes acolhidos possam exercer seus direitos de retornarem ao convívio familiar e suas institucionalizações não se tornem naturais e perenes. Para os que não puderem ser (re) inseridos na família, o abrigo necessita ser espaço de real (re) construção de vidas. Desta forma, a instituição abrigo, em sua maioria, carece re (ver) seus paradigmas e re (significar) seus espaços institucionais no sentido de fazer valer o direito às Crianças e adolescentes de terem direitos. / This doctoral thesis proposes to analyze the life history of an adolescent with intellectual disability residing in an institutional shelter unit. We conducted this research based on two major questions: 1) How this adolescent, doubly excluded by neglect and disability, interpreted his life situation and how his perceptions were incorporated; 2) and about his life history and adult life expectation, which were: work, professionalization, affective relationships and sexuality. We had, as general objective, to rescue the life history of an adolescent, welcomed in an institutional shelter and, as specific objectives, to rescue his life history from the point of view of his narrative: birth and childhood development; to collect data about his schooling: educational mode and trajectory, and analyze his perception about the schooling process. This is a qualitative research based on the Life History. For data collection, we used an open interview containing themes that enabled us to know the life trajectory of the adolescent under study. The subject's narrative allowed us to construct four themes: 1 – Family history: marks of homesickness; 2 – History of the shelter: marks of exclusion; 3 – History of schooling: inclusion, after all? 4 – History of future perspective and transition to adult life. Inclusive perspectives? This study revealed that the adolescent, like any other of his age, has dreams and future prospects, which, through his life history and reality in the institutional shelter, he must have difficulties to materialize. According to Sávio (fictitious name), his schooling is complex and he can’t follow the teaching and learning process of other regular students. The Child and Adolescent Statute foresees an efficient legislation that allows the viability of a transforming praxis of social insertion and overcoming social exclusion. However, we were faced with this research, which suggests to the shelter unit the need for real changes in its paradigms and (re) significances of its institutional space so that the sheltered children and adolescents can exercise their rights to return to family life and their institutionalization does not become natural and perennial. For those who can’t be (re) inserted into the family, the shelter needs to be a space of real (re) construction of lives. Thus, the shelter institution, mostly, lacks re (seeing) its paradigms and re (signify) its institutional spaces in order to assert the right of children and adolescents to have rights.

Passive radar is a technology for detection of targets using echoes of existing radio transmitter, such as FM-radio. Since only receivers are needed for operation, a passive radar system has the possibility of being implemented using low-cost hardware. Using lower cost implementations to cover blind-spots of other, more sophisticated systems, could be a viable solution for full radar coverage. To achieve this, an understanding of the effects such low-cost systems have on the performance of a radar is needed.  A prominent problem for passive radar is that the interference caused by the direct signal from the transmitter used and reflections from uninteresting terrain, called clutter, can drown out the echoes from targets. This thesis compares the direct signal interference (DSI) suppression algorithms: ECA, ECA-S, ECA-B, NLMS and FBNLMS when run on data from a low-cost receiver called KerberosSDR. It is found that the low ADC resolution of 8 bits is a limiting factor for KerberosSDR. Random noise in the receiver can also limit the performance. None of the tested algorithms are any more or less affected by the ADC resolution or the noise. The first difference appears when comparing the execution times, where FBNLMS is 10–20 times faster than the other algorithms. However, the slower rate of convergence for FBNLMS and NLMS causes them to lose performance in environments where the DSI and clutter are considerably stronger than the target echoes. The algorithms FBNLMS and NLMS also lose performance due to their inability to model frequency shifted echoes as unwanted. The main disadvantages of ECA, ECA-B and ECA-S are their long execution time. It is concluded that FBNLMS would be the best candidate in most cases for low-cost hardware, as it allows execution on slower hardware and the main disadvantages not being too prominent in the use case of covering blind-spots of other systems.

Sedan industrialismens start har människan påverkat klimatbalansen genom förbränning av fossila bränslen. Rökgasemissionerna förorsakade av internationell sjöfart kan inte tillskrivas någon särskild nations ansvar på grund av dess globala och komplicerade verksamhet. FN:s sjöfartsorgan IMO har således åtagit sig ansvaret att minska sjöfartens miljöpåverkan. Införandet av nya miljömål har resulterat i strängare globala och nationella regler som tvingar sjöfartsnäringen till omfattande anpassningar under kort tid. Som lösning för att uppfylla kommande krav gällande rökgasemissioner har flertalet alternativa bränslen diskuterats. Drift på metanol medför låga rökgasemissioner och anses därav ha potential till att bli ett hållbart bränsle inom sjöfarten. Studiens syfte har varit att undersöka vad rederier, maskintillverkare och klassningssällskap anser om metanol som ett alternativt bränsle. Inledningsvis genomfördes en litteraturstudiedel som sedan låg till grund under utformandet av intervjufrågorna. Resultatet visar att metanol anses ha stor potential i jämförelse med andra alternativa bränsle. Då metanol kan produceras från överskottsenergi och transport kan ske med befintlig infrastruktur betraktas det både miljövänligt och ekonomiskt försvarbart. Likväl medför det kraftigt varierande metanolpriset att rederier hämmas att satsa på utvecklingen som krävs för att realisera metanoldrift av fartyg. / Since the start of industrialization humans have affected the climate balance by burning fossil fuels. Exhaust gas emissions caused by the international shipping cannot be attributed to any particular nation because of its global and complex business. The International Maritime Organisation has therefore undertaken the responsibility to reduce the environmental impact of shipping. The introduction of new environmental goals has resulted in stricter global and national regulations that force the shipping industry to make significant adjustments in a short period of time. As a solution to meet future requirements for exhaust gas emissions several alternative fuels have been discussed. Operating vessels on methanol results in low exhaust gas emissions and is therefore considered to have the potential to become a sustainable fuel for the shipping industry. The aim of this study was to investigate what shipping companies, machine manufacturers and classification societies considers about methanol as an alternative fuel. Initially, a literature study was implemented which formed the basis of the interview questions. The result shows that methanol is considered to have great potential compared with other alternative fuels. Since methanol can be produced from excess energy and transportation can be done with existing infrastructure methanol is considered both environmentally friendly and economically viable. Nevertheless, the highly fluctuating methanol price can causes shipping companies to hesitate in the financing of developments that is necessary for the realization of methanol operation on board vessels.

Esta tese estuda atitudes e comportamentos dos alunos de Publicidade e Propaganda da ECA/USP quanto ao seu relacionamento com o curso. Através de pesquisas qualitativas procurou verificar as expectativas e as motivações de vestibulandos e ingressantes no tocante ao aprendizado acadêmico e à carreira, e com a realização de pesquisas quantitativas buscou medir o grau de satisfação com o curso e a escola, bem como as principais razões de satisfação / insatisfação. Verificado que muito da insatisfação e da decepção dos alunos origina-se de uma imagem estereotipada da carreira e do pouco conhecimento do curso, o autor procurou mostrar que é possível minorar estes sentimentos dos alunos e motivá-los às atividades acadêmicas usando os próprios instrumentos que a escola se propõe a ensinar, ou seja, as técnicas de comunicação persuasiva. / This thesis study all attitudes and behaviour from Advertising students of ECA/USP related to their course. By qualitative researches the author tried to verify the expectation and motivation that concern all beginners and students who are starting their academic life and their careers. By quantitative researches he tried also measure the degree of satisfaction from new students related to their course and school. Moreover he found the real purposes of satisfaction and dissatisfaction of these students analysed. The degree of dissatisfaction and deception that showed all students analysed became from the stereotype career and unknown description that they are from their course. The author tried to show that is possible to minimize these feelings and motivate all students towards academic activities by tools who are originally teaching at school as persuasive communication techniques.

Este estudo tem como objetivo central identificar e problematizar os impactos e dilemas do ECA junto à Justiça do Trabalho TRT 12, durante a década de 1990, na cidade de Florianópolis, tendo em vista ser esse o período de implementação do Estatuto. A partir da análise de um corpus documental de 300 ações processuais trabalhistas, obtidas no Arquivo do Serviço de Digitalização e Guarda, buscamos perceber como e se os operadores/as do Direito do Trabalho remetiam-se ao ECA na formulação dos documentos que compunham os autos do Judiciário Trabalhista. Nessas ações, dentre as quais, 299 foram aJuizadas por trabalhadores e trabalhadoras com idade inferior a dezoito anos e uma pelo Ministério Público do Trabalho, nos foi possível verificar como se constituíam as relações de trabalho entre empregadores/as de diferentes setores e empregados/as infantojuvenis, em uma Florianópolis que passava por profundas transformações urbanas com um quadro de aumento demográfico resultante de um significativo processo migratório. A década de 1990, no Brasil, foi marcada por uma aplicação de políticas neoliberais, que teve como consequência o aumento das taxas de trabalho informal, de dessalariamento e de desemprego, provocando uma situação socioeconômica de maior vulnerabilidade, sobretudo, no que tange às famílias pobres. Como decorrência dessa situação, acentuaram-se as taxas de trabalho infantil ilegal e juvenil ilegal e/ou irregular em todo o país, e em especial na cidade de Florianópolis, onde nos foi possível mapear o lugar ocupado pelos contingentes infantojuvenis protagonistas desta história. Os dilemas do ECA quanto ao trabalho infantojuvenil estão relacionados à necessidade que famílias empobrecidas têm de se utilizarem dessa mão de obra para a própria subsistência. Os impactos relativos a esse Estatuto na sociedade brasileira são muitos, como é o caso da Ação Civil Pública, que contando com a atuação conjunta do Ministério Público do Trabalho, da Delegacia Regional do Trabalho, do Conselho Tutelar da Criança e do Adolescente de Florianópolis e do TRT 12 levou à erradicação das atividades de jornaleiro/a e encartadores de jornais, formas de trabalho infantojuvenil que perduraram por muitas décadas na cidade de Florianópolis. Verificamos, por fim, que para a erradicação do trabalho infantil e para a regularização do trabalho juvenil faz-se necessária a efetivação de um conjunto de políticas públicas voltadas à melhoria de renda dessas famílias, para que não dependam dessa força de trabalho, assim como dos demais direitos, educação, saúde, cultura, lazer e etc., reconhecidos à infância e à adolescência. / The present thesis has as its goal to identify and discuss the impacts and dilemmas raised by the Brazilian Child and Adolescent Rights Act (ECA) in the sphere of action of the Labor Courts (TRT 12) in the city of Florianopolis (Brazil), during the 1990s, in which context that legislation was introduced. From the analysis of 300 labor lawsuits located in the official Digital Archives of that institution, I seek to understand the means by which the labor law operators made use of and referred to the ECA in order to formulate the documents that based the judiciary processes. In the set of those lawsuits, 299 were filed by workers of under eighteen years old and one by the Labor Public Ministry. By the analysis of the documents is possible to identify how were formed working relationships between employers and young workers in different economic sectors of a town that was passing by deep urban transformations linked to the migration process and the population growth. The 1990s in Brazil was marked by the introduction of neoliberal policies, which led to an increase in informal employment rates, cheap labor and unemployment, causing a social and economic situation of greater vulnerability, especially among poor families. As a result of it occurred the increasing of illegal or irregular child and juvenile labor rates in Florianopolis. This study shows the place occupied by those young workers protagonists of this narrative in the recent social and economic processes of that city. The dilemmas that have been raised since the introduction of ECA are related to the needs ofpoor families, which depend on children and youngslabor fortheir livelihood. There are many impacts of ECA in the Brazilian society, such as the Public Civil Action, which involves joint efforts of the Ministry of Labor, the Regional Labor Office, the Council of Guardianship of Children and Adolescent and the Labor Court (TRT 12), which led to the eradication of the paperboys activities, a form of work that lasted for many decades in Florianopolis. Finally, this thesis demonstrates thatthe eradicationof child labor andthe regularizationof youth work should be a part of a broad set ofpublic policies aimed atimproving the incomeof poor families,so that they do notdepend onthislabor force, as well as children and adolescents must be recognized as holders of rights in terms of education, health, culture, recreation and so on.
