Relatório de estágio curricular no Ministério Público na Comarca de Setúbal

This report represents four months of study on activities in the public prosecution service at the Local Instance of Setúbal judiciary district, started in September 2014 and completed of the same year. This report was prepared considering all the teachings of criminal law courses and criminal procedural law, doctrine, jurisprudence and all the practical experience experienced with prosecutors. In this context, their traineeship provided contact with different procedural stages: the investigation stage that allowed to understand better the progress of the processing of summary proceedings; the expedient distribution of urgent cases; the investigation stage, as regards the procedural impulse assistant and the accused; and the trial stage. This last phase allowed contact with different types of crimes especially road crimes and the crime of domestic violence. The analysis carried out the summary proceedings in the Public Ministry service would acquire relevant information to explain the incidence of road crimes. Topics will be addressed that were found on stage during the various procedural stages, as the implementation of new judicial map. The relationship between the prosecution and the Criminal Police Bodies was also an issue to be addressed. The work also raises awareness of the issue of archives in order to find out the position of assistant.

Engineering bio-based polymers using alternative solvents and processes

The work presented in this thesis explores novel routes for the processing of bio-based polymers, developing a sustainable approach based on the use of alternative solvents such as supercritical carbon dioxide (scCO2), ionic liquids (ILs) and deep eutectic solvents (DES). The feasibility to produce polymeric foams via supercritical fluid (SCF) foaming, combined with these solvents was assessed, in order to replace conventional foaming techniques that use toxic and harmful solvents. A polymer processing methodology is presented, based on SCF foaming and using scCO2 as a foaming agent. The SCF foaming of different starch based polymeric blends was performed, namely starch/poly(lactic acid) (SPLA) and starch/poly(ε-caprolactone) (SPCL). The foaming process is based on the fact that CO2 molecules can dissolve in the polymer, changing their mechanical properties and after suitable depressurization, are able to create a foamed (porous) material. In these polymer blends, CO2 presents limited solubility and in order to enhance the foaming effect, two different imidazolium based ILs (IBILs) were combined with this process, by doping the blends with IL. The use of ILs proved useful and improved the foaming effect in these starch-based polymer blends. Infrared spectroscopy (FTIR-ATR) proved the existence of interactions between the polymer blend SPLA and ILs, which in turn diminish the forces that hold the polymeric structure. This is directly related with the ability of ILs to dissolve more CO2. This is also clear from the sorption experiments results, where the obtained apparent sorption coefficients in presence of IL are higher compared to the ones of the blend SPLA without IL. The doping of SPCL with ILs was also performed. The foaming of the blend was achieved and resulted in porous materials with conductivity values close to the ones of pure ILs. This can open doors to applications as self-supported conductive materials. A different type of solvents were also used in the previously presented processing method. If different applications of the bio-based polymers are envisaged, replacing ILs must be considered, especially due to the poor sustainability of some ILs and the fact that there is not a well-established toxicity profile. In this work natural DES – NADES – were the solvents of choice. They present some advantages relatively to ILs since they are easy to produce, cheaper, biodegradable and often biocompatible, mainly due to the fact that they are composed of primary metabolites such as sugars, carboxylic acids and amino-acids. NADES were prepared and their physicochemical properties were assessed, namely the thermal behavior, conductivity, density, viscosity and polarity. With this study, it became clear that these properties can vary with the composition of NADES, as well as with their initial water content. The use of NADES in the SCF foaming of SPCL, acting as foaming agent, was also performed and proved successful. The SPCL structure obtained after SCF foaming presented enhanced characteristics (such as porosity) when compared with the ones obtained using ILs as foaming enhancers. DES constituted by therapeutic compounds (THEDES) were also prepared. The combination of choline chloride-mandelic acid, and menthol-ibuprofen, resulted in THEDES with thermal behavior very distinct from the one of their components. The foaming of SPCL with THEDES was successful, and the impregnation of THEDES in SPCL matrices via SCF foaming was successful, and a controlled release system was obtained in the case of menthol-ibuprofen THEDES.

Marketing plan for online aqctivity of Rota Vicentina boosting direct website sales

The nature tourism experienced a great expansion of its market with the appearance of different lifestyles. In this Work Project a study regarding the website direct sales of Rota Vicentina was developed. Its website shows the idea of being solely an information structure and not a purchase one, leading to a current absence of online sales. Hence, it is suggested the modification of its business model, using different instruments and channels. Some digital marketing recommendations were developed in order to boost website sales, such as a platform for online reviews, remarketing campaigns and social media activity.

Social venture move

This study has the purpose of presenting the path of a social microcredit start-up in Mozambique. Its members had just gotten out of college and decided to put in practice what they had learnt. Even though the whole foundation of the project was developed in Mozambique, the team has extended its experience to other countries: São Tomé and Timor. However, the focus of this study will be solely in the Ilha de Mozambique’s project and the difficulties that it is facing right now, in order to try to find answers that would allow the project entrepreneurs to overcome what is keeping them from having a more successful return rate. The main issue of the project and the worse and unexpected default rate is within the fishing sector. This is peculiar, since the mission is in an island where there are plenty of fish and shellfish. By addressing this problem, and presenting the whole structure of the venture, it is its goal to understand better ways to deal with the difficulties. Its format will be as a case study and it will present as well the macroeconomics of Mozambique to justify the choice of the place, align with the team itself, and why it is possible to have a successful project with as many contacts and sponsors as this one does.

Avaliação da implementação da fase III da zona de emissões reduzidas de Lisboa

Os efeitos de uma qualidade do ar reduzida são sentidos principalmente em centros urbanos, como Lisboa, onde persistem situações de concentrações elevadas de dióxido de azoto (NO2) e matéria particulada (PM10), originadas pelo tráfego automóvel. Para diminuir a concentração desses poluentes foi implementada uma Zona de Emissões Reduzidas (ZER) em Lisboa, que entrou na fase III em janeiro de 2015. Avaliou-se a evolução da qualidade do ar nos últimos cinco anos em Lisboa, nomeadamente as excedências aos valores limite legais de curto prazo para NO2 e PM10, bem como a influência da meteorologia na sua ocorrência. A qualidade do ar, em geral, melhorou, registando-se a maioria das excedências no outono e inverno, em dias úteis e final da tarde e início da manhã, períodos coincidentes com a maior intensidade de tráfego rodoviário. A altura da base da inversão térmica e a velocidade do vento são mais reduzidas em dias com excedências, o que indicia um papel relevante da meteorologia. A avaliação do impacte da fase II da ZER nas excedências aos valores limite revelou que o número de excedências e a duração dos episódios de poluição diminuíram, mas mais significativamente em estações fora da ZER. Analisou-se a influência da fase III da ZER na composição da frota automóvel e nas emissões associadas de NOX e PM na Avenida da Liberdade, com base nos dados obtidos antes (2014) e depois (2015) da fase III. Verificou-se uma melhoria na frota em toda a cidade, mais acentuada na zona 2 que na zona 1. Concluiu-se que o impacte da fase III foi reduzido, principalmente na zona 1, possivelmente relacionado com a escassa fiscalização. Caso o número de veículos se tivesse mantido igual entre 2014 e 2015, teria sido possível uma redução de 23% nas emissões de NOX e de 8% nas de PM.

Modelo preditivo de insolvência no setor farmacêutico : aplicação à farmácia comunitária portuguesa

O setor farmacêutico apresenta um elevado grau de complexidade, dada a regulamentação a que está sujeito. Atualmente, um dos principais problemas deste setor prende-se com o acentuado aumento (142,6% entre dezembro de 2012 e julho de 2014) do número de farmácias insolventes, sendo impacto da crise económica e consequentes medidas regulamentares aplicadas com o Memorando de Entendimento da Troika. Dada a importância que as farmácias têm na dispensa do medicamento assim como o papel do farmacêutico no aconselhamento diário aos utentes, a redução do número de farmácias levanta problemas no acesso ao medicamento por parte da população. Assim, é necessário dotar as farmácias de ferramentas que lhes permitam gerir o seu negócio, criando bases sólidas de forma a terem uma maior capacidade de reagir em tempos de crise. Desta forma, o objetivo principal do trabalho é fornecer às farmácias uma dessas ferramentas, através da criação de um modelo preditivo de insolvência que permita estimar uma probabilidade de uma farmácia entrar em insolvência. Para o efeito, desenvolveu-se um modelo teórico, com base na revisão de literatura científica e na análise do setor farmacêutico em Portugal, que foi depois testado recorrendo a métodos de estimação com recurso ao modelo logit através do método da Máxima Verosimilhança. O modelo empírico foi estimado com dados de uma amostra de 97 farmácias, selecionadas a partir de uma base de dados da ANF. Esta amostra é composta por todas as farmácias insolventes e por uma seleção aleatória de farmácias solventes, para as quais foi possível utilizar informação proveniente do IES, mantendo a total confidencialidade, nomeadamente dados relativos às dimensões consideradas no modelo teórico: Autonomia Financeira, Endividamento, Gestão de Inventários, Gestão de Funcionários, Liquidez, Prazo Médio de Pagamentos do Estado, Prazo Médio Pagamentos a Fornecedores, Rendibilidade, Solvabilidade, Tesouraria, Dimensão e Localização. As dimensões referidas foram selecionadas após uma análise extensiva da bibliografia sobre esta temática. Estas dimensões foram incluídas na estimação através de variáveis proxy (com exceção da Tesouraria), para as quais foi também levada a cabo uma análise de sensibilidade. Depois de validados os pressupostos da estimação e de uma análise crítica sobre os resultados, foi possível selecionar um modelo em que mais de 90% das observações foram classificadas corretamente. O modelo preditivo selecionado inclui as variáveis proxy das dimensões: Autonomia Financeira, Prazo Médio Pagamentos a Fornecedores, Endividamento, Rendibilidade, Dimensão e Localização. Em testes posteriores, validou-se a capacidade preditiva do modelo com recurso a uma amostra de teste.
