Seguimiento serológico de infección por Trypanosoma cruzi en individuos estudiados de 50 municipios del Estado de Jalisco, México de 1987 a 1994

La Universidad de Guadalajara decidió realizar en 1987 un estudio seroepidemiológico para conocer la prevalencia de la infección por Trypanosoma cruzi en los 124 municipios del Estado de Jalisco, México, en el cual se obtuvieron tasas de 21,6 por 100 habitantes. De diciembre de 1993 a junio de 1994 se realizó un seguimiento de algunos de esos individuos, estudiándose sólo 2669 de ellos, de 50 municipios de áreas rurales del estado. Las causas de no encuesta de los faltantes fueron diversas, estando entre las más importantes la emigración (27,6) y la renuencia (14,8). Encontramos a 476 positivos (17,8%) y 2193 negativos (82,2%). Este segundo estudio nos permitió detectar 80 infectados nuevos (2,9%) lo que representa una tasa de incidencia de 30 por 1000 habitantes. Sin embargo, encontramos una seroconversión en los individuos estudiados, ya que de 1007 individuos que estaban positivos en 1987, 943 de ellos continúan así, mientras, que 64 individuos se negativizaron (2,3%), no siendo esto imputable a fallas de laboratorio, la prevalencia de positividad detectada en ambos estudios fue casi idéntica 18,1 y 17,8 % respectivamente, por lo que nosotros pensamos que las condiciones en que viven los individuos de las localidades rurales del Estado de Jalisco favorecen a que las infecciones continúen.

Prevalência de triatomíneos (Hemíptera: Reduviidae: Triatominae) infectados por Trypanosoma cruzi: sazonalidade e distribuição na região Ciénega do Estado de Jalisco, México

As características físico-geográficas da região Ciénega, Jalisco, México a tornam propícia para transmissão do Trypanosoma cruzi, causador da doença de Chagas. Este trabalho caracteriza a prevalência de triatomíneos infectados pelo parasita, sua sazonalidade e distribuição nesta região. Foram analisados 328 triatomíneos no período de janeiro de 2005 a junho de 2007 procedentes de 13 municípios da região, sendo abril, maio e junho os meses de maior captura. Dos triatomíneos analisados, 57,3% foram positivos para Trypanosoma cruzi, correspondendo 15,4% para a área urbana e 84,6% para a área rural. A espécie mais freqüente foi Triatoma longipennis e a mais parasitada foi Triatoma barberi com índice de infecção de 83,3% quando comparada a Triatoma longipennis (67,5%) (p<0,05). A infecção natural dos vetores capturados pode indicar alta exposição das pessoas ao Trypanosoma cruzi. O achado recente do Triatoma dimidiata positivo nesta região, sugere a adaptação de novas espécies às condições ecológicas destas populações.

O contrato de Project Finance

Currently, Angola portrays a notorious economic growth and due to recent innovative legislations, it has become the major investment attracting pole, especially in Sub-Saharan Africa, having, thus, an extraordinary potentiality for a rapid and sustainable development, likely to place her in outstanding positions in the world economic ranking. Yet, such economic growth entails demanding levels of intensive investment in infrastructure, what has been reported of the Angolan Government to be unable to respond to, save if recurring to very high index of external debt, poisoning, in this way, the future budgeting of the country. Due to these infrastructure investment shortages, the cost of production remains highly onerous and the cost of life extremely unaffordable. On this account, the current study disserts about the contract of Project Finance; an alternative finance resource given as a viable solution for the private financing of infrastructure, aiming to demonstrate that such contractual figure, likewise the experience of several emerging economies and others, is a contract bid framework to take into account in today’s world. It refers to a financing technique – through which the Government may satisfy a common need (for example, the construction of a public domain or public servicing), without having to pay neither offer any collateral – based on a complex legal-financial engineering, arranged throughout a coalition of typical and atypical agreements, whereby it is mandatory to look back at the basic concepts of corporate law. More than just a simple financial study, the dissertation at stake analyses the nature and legal framework of Project Finance, which is a legally atypical and innominate contract, concluding that there is a relevant need for regulating and devoting a special legal regime in the Angolan jurisdiction for this promising legal form in the contemporary corporate finance world.

La recherche que nous avons mené à bien avait pour but, dans un premier temps de comprendre la notion de contrat, ses caractéristiques, fonctions et les garanties qui en peuvent être fournies. Nous invoquerons le contenu du contrat, c'est à dire, les effets de celui-ci en essayant de montrer les droits et obligations auxquels les parties seront liées. Bien qu'étant un contrat assez requérant dans la pratique bancaire, celui-ci n'a pas encore attiré l'attention du législateur de façon à établir un régime qui pourrait lui être appliqué au lieu de s'appuyer sur d'autres contrats lui étant similaires. Nous proposons l'analyse de la cessation du contrat, en se concentrant sur les moyens de la dissolution, survenue suite à la conclusion de l'accord comme la plainte, l'abrogation, l'expiration et la résolution du contrat, en laissant de côté la dissolution du contrat pour des raisons survenues avant la conclusion du contrat, comme la nullité et l'annulation.

O incumprimento do contrato de crédito ao consumo pelo consumidor

Consumer relations, established between the Consumer and the Creditor, which carry a consequent inequality of contractual positioning between the parties, have been pushing the legislator to adopt more rigid regulations with regard to lending for the purchase of goods or services of consum issues. In this sense, the Decree-Law 359/91 was approved, meanwhile repealed by the Decree-Law 133/2009, which regulates the consumer credit agreement’s regime in the portuguese legal system. Through this contract, the financier makes available to the consumer a certain amount of money, which the consumer must repay, plus the respective remuneration (interest) and other charges, according to a refund plan agreed by the parties. The consumer will be in delay if he breaches this stipulation. In case of default, the creditor, notwithstanding, can choose to wait for the performance by the debtor, promote the loss of benefit of the term or the termination of the contract. From the outset it would seem that, in one way or another, the financier, by imposing a forced shortening of the contract duration initially agreed, will lose the right to remuneration for the provision of capital agreed, but not verified. Nevertheless, unlike presently, the previous regime allowed the parties to rule otherwise, being permitted to agree to the payment of interest of outstanding installments. On the other hand, in the consumer credit contract the principle of freedom of contractual provision of the parties is strongly mitigated by the special legislation, which prevents the waiver of rights by the consumer, and by the regime of general contractual terms, which restricts the freedom of the financier to stipulate the contractual content freely and the freedom of the consumer to negotiate. For all these reasons, associated with the growing need of credit resource to satisfy their needs of consumption, it is confirm the relevance of legislative intervention on consumers protection in the context of hiring credit.

Gestão eficiente da energia eléctrica no edifício da Biblioteca da FCT e negociação de um novo contrato em mercado liberalizado

Nos últimos anos, a energia eléctrica tem vindo a conquistar, um lugar cada vez mais importante na sociedade, sendo nos nossos dias um bem essencial para o funcionamento normal das residências, empresas, indústrias e cidades. O problema que a presente dissertação analisa é transversal a inúmeros edifícios, que consomem diariamente uma grande quantidade de energia eléctrica, na ordem dos 900 kWh diários, ou mesmo superior. Desta forma, considera-se o consumo de eletricidade, e potenciais ineficiências no seu uso, num edifício universitário, nomeadamente a biblioteca da Faculdade de Ciências e Tecnologia (FCT) da Universidade Nova de Lisboa (UNL). Em termos mais específicos, pretende-se definir um consumo de energia mais eficiente, deslocando consumos de uns períodos horários para outros, onde as tarifas sejam mais económicas, aplicando medidas de participação ativa dos consumidores (PAC). Além disso, pretende-se simular a negociação de um novo contrato bilateral, entre um retalhista e um agente “gestor” da biblioteca da FCT, para obter um contrato melhorado, do ponto de vista do consumidor. Os principais objetivos desta dissertação são, deste modo, os seguintes: (i) estudar a contratação bilateral de energia em mercados liberalizados, com principal ênfase para a implementação de estratégias de negociação que possibilitem uma participação ativa dos consumidores, (ii) estudar a biblioteca da FCT e propor medidas de eficiência energética, e (iii) simular a negociação de um novo contrato bilateral, recorrendo ao simulador multi-agente MAN-REM. De forma sucinta, os resultados obtidos, permitem concluir que o consumo energético da biblioteca da FCT pode ser melhorado, e com base nos volumes de energia deduzidos, é possível negociar um novo contrato, mais favorável à FCT.

Kixikila - um contrato de financiamento informal

The purpose of the present work is to analyse and provide kixikila legal framework under Angolan law. Kixikila, despite being a legally atypical agreement, is a socially typical contract, governed essentially by the practices and customs in Angola and concluded throughout the country. With the above purpose in mind, this thesis is structured in five chapters: the first one aims at better understanding its features and, therefore, it describes the kixikila in accordance with oral research, direct observation and the contributions of scholars that have examined this matter. The second chapter aims at qualifying the kixikila as a legal transaction. For this purpose, we have analysed its requirements, formation stages, content and form, characteristics, rights and obligations of the parties, effects and compliance. We have also covered the reasons that explain why this type of agreement shall be legally protected in line with the protection conferred upon other legal agreements, taking into account its economic and social function. The third chapter covers the vicissitudes which may occur during the term of the kixikila agreement, as well as the enforcement mechanisms in face of breach and its termination. The fourth chapter aims at qualifying this agreement by comparing its most relevant characteristics with those of typical agreements, with a view to determining its legal nature based upon the similarity with other contractual types. This chapter further makes a comparative synthesis between the contracts in analysis. The fifth chapter analyses the legal nature and legal framework applicable to kixikila taking into account mixed-purpose contracts and sui generis contracts. We conclude that practices and customs in Angola take precedence as regards kixikila. Lastly, we attach additional information, such as excerpts of interviews with some individuals intervening in kixikila, the functional structure of kixikila and examples of kixikila, as well as demonstrative lists of countries where this type of agreement takes place and the obligations arising therefrom.
