Developing Optical Character Recoginition for Ethiopic Scripts

The Amharic language is the Official language of over 70 million people mainly in Ethiopia. An extensive literature survey and the government report reveal no single Amharic character recognition is found in the country. The Amharic script has 33 basic characters each with seven orders giving 310 distinct characters, including numbers and punctuation symbols. The characters are visually similar; there is a typeface, but no capitalization. Beside this there is no any standard font to use the language in the computer but they use different fonts developed by different stakeholders without keeping a standard on their own way and interest and this create a problem of incompatibility between different fonts and documents.This project is to investigate the reason why Amharic optical character recognition is not addressed by local and international researchers and developers and finally to develop Amharic optical character recognition uses the features and facilities of Microsoft windows Vista or 7 using Unicode standard.

The Pollination Biology and Mating System of a Peripheral Population of Witheringia solanacea (Solanaceae)

Pollinator visitation rates over the life of a flower are determined by pollinator abundance and floral longevity. If flowers are not visited frequently enough, pollen limitation may occur, favoring the evolution of self-compatibility (SC). In plant species with varying SC levels, central populations often are self-incompatible (SI) and peripheral populations are SC. Witheringia solanacea (Solanaceae) is a species that follows this trend with the exception of one population in the Monteverde Cloud Forest Reserve, which is peripheral yet SI. I investigated this population using multiple techniques including floral bagging, pollinator observations, microsatellite analysis, and floral longevity manipulations. My results confirmed the self-incompatibility of the Monteverde population and indicated low but perhaps adequate rates of pollinator visitation per flower per hour. I found reduced genetic diversity at Monteverde and gene flow occurring unidirectionally from San Luis (a central population) to Monteverde. In the greenhouse, there was more of an effect of male than female function on floral longevity, but the largest differences were environmental. Flowers stayed open substantially longer when cool, cloudy weather was simulated and shorter when conditions were hot and sunny. The results indicate that the Monteverde population of W. solanacea is SI because 1) it is unable to maximize its fitness due to gene flow from San Luis and its relatively recent colonization of the area and 2) pollen limitation may not be severe because of supplemental pollinator availability from other Witheringia species in the area and increased floral longevities due to cool and cloudy conditions.

A Pollen Chase Experiment; Examining Varying Levels of Embryonic Inbreeding Depression

A pollen chase experiment was performed upon three Costa Rican populations of Witheringia solanacea to examine the breakdown of genetically enforced self incompatibility (SI) and the extent of embryonic inbreeding depression. Self-pollen was applied in the bud, with outcross pollen applied one day later, and outcross pollinations at both intervals as a control. A variety of responses were found among the populations. BOHS readily accepted self pollen and suffered from very low inbreeding depression. Monteverde and Las Cruces both have lower fruit set with self-pollination precedence indicating that bud pollinations can overcome the self-incompatibility response and that embryonic death due to inbreeding depression causes fruit failure. The treatment:control fruit set is higher for the Las Cruces plants indicating stronger SI response Self-precedence seeds from the Las Cruces plants are likely to be outcrossed. Self-precedence seeds from Monteverde are likely selfed.

Gestão de transferência de inovações tecnológicas para empresas do setor produtivo: complexidade no relacionamento entre organizações de culturas diferentes

The motivation of this study is based on the expectation of understanding, at least in part, the reason why the brazilian academic production ¿ which is among the largest if compared to the developing countries, has not been translated in a useful way into concrete technology transference for the production sector. The supposition that different cultures and subcultures, in terms of values, behavior, practices among organizations and groups of selected actors involved in that process,- which is the central problem of this study, and peculiar to the technology context, has elected that relationship process the object of this research this study theoretical fundaments rely on culture and technology to analyze the subcultures which manifest themselves through the typified groups of researchers, in the public organizations, small scale employers, acting on technology based companies in the private sector (ebts) and mediators. Who also act in the process the preliminary step was the case study. Several qualitative methods an procedures were used. And the investigation has advanced toward interacting interviews, at the end added by the focal group method. The conclusions reject the existence of incompatibility among the subject groups points of view, however, points out some divergent values, the presence of mutual stereotypes and also confirms the supposition that the research platform is strongly influenced by the financial factor. Although, the study reveals that the presence of common objectives which lay behind the cited divergences make possible to present a core of practical suggestions to implement the studied relationships for the benefit of the production sector as well. The peculiarities perceived while dealing with that singular context suggest futures research to clarify possible new and obscure areas in that complex relationships.

Islamic law and international law: the terms of a relationship

The relationship between Islamic Law and other legal systems (basically western type domestic legal orders and international law) is often thought of in terms of compatibility or incompatibility. Concerning certain subject matters of choice, the compatibility of Islamic (legal) principles with the values embedded in legal systems that are regarded as characteristic of the Modern Age is tested by sets of questions: is democracy possible in Islam? Does Islam recognize human rights and are those rights equivalent to a more universal conception? Does Islam recognize or condone more extreme acts of violence and does it justify violence differently? Etc. Such questions and many more presuppose the existence of an ensemble of rules or principles which, as any other set of rules and principles, purport to regulate social behavior. This ensemble is generically referred to as Islamic Law. However, one set of questions is usually left unanswered: is Islamic Law a legal system? If it is a legal system, what are its specific characteristics? How does it work? Where does it apply? It is this paper`s argument that the relationship between Islamic Law and domestic and international law can only be understood if looked upon as a relationship between distinct legal systems or legal orders.

Audiência única e a duração razoável do processo nos juizados especiais cíveis

Esta dissertação pretende demonstrar que os Juizados Especiais Cíveis Estaduais, regulados pela Lei n° 9.099/95, orientados pelos princípios da oralidade, simplicidade, informalidade, economia processual e celeridade, que foram criados em decorrência da necessidade de viabilizar um maior acesso à justiça, principalmente da população mais carente, com redução de custos e simplificação de procedimentos que possibilitassem os julgamentos dentro de um prazo razoável, na realidade da práxis forense, estão sendo desvirtuado dos seus objetivos. Neste sentido, o estudo apresenta números comprovando que os Juizados Especiais cumpriram seu desiderato de proporcionar o acesso ao judiciário, mas que passaram a padecer do mesmo problema da justiça comum: a morosidade na entrega da prestação jurisdicional. Além da incompatibilidade de estrutura com a atual demanda que obviamente vai ensejar lentidão nos Juizados, o estudo apresenta como motivo para esse quadro a conduta dos juizes, responsáveis pela administração do processo, que reproduzem nos Juizados o fomlalismo e a burocracia inerente ao processo civil comum, ao instituir, em evidente descompasso com a lei e seus princípios, um procedimento com duas audiências, sendo uma para conciliação e outra, nos casos em que não é obtido acordo, para instrução e julgamento, em dias distintos, aumentando o tempo de duração dos processos. O estudo conclui que a utilização de audiência única, além de ser uma detenninação legal e estar em sintonia com seus princípios, proporciona celeridade nos julgamentos. diminuindo o custo e o tempo de espera dos litigantes, obstáculos do acesso à justiça que a Lei n° 9.099/95 procurou remover.

Moedas sociais digitais: estudo de caso de duas experiências em bancos comunitários

Este trabalho parte de duas experiências de implantação de moedas sociais digitais pelo poder público para responder se a introdução de uma tecnologia de pagamentos digital, em conjunto com moedas sociais, pode modificar conceitos básicos de comunidade e sociedade ou se é a tecnologia que precisa se adaptar a estes conceitos. Com os casos representando polos opostos na teoria de Tönnies em termos de comunidade/sociedade, têm-se como hipótese que a introdução da tecnologia em moedas sociais precisa estar em linha com conceitos básicos de comunidade, solidariedade, pertencimento, entre outros, de acordo com o frame de cada experiência. Como resultado, há poucas evidências que possam ser tidas neste momento como definitivas. Resta especular que o uso da tecnologia de pagamentos digitais como forma de ganho de escala do modelo de economia solidária em sociedades do tipo gemeinschaft encontra falta de elementos facilitadores que incentivem sua implementação e uso, sendo que, novamente, indaga-se que as tecnologias disponíveis de moedas sociais digitais parecem ser pouco congruentes com o próprio conceito de comunidade que faz parte do cerne da economia solidária e de sociedades locais do tipo gemeinschaft, podendo haver maior proximidade com sociedades do tipo gesellschaft. Em adição a isto, especula-se que (1) mesmo havendo êxito na implantação de moedas sociais digitais em comunidades do tipo gemeinschaft, que isto somente se confirmará mediante a criação de um modelo inovador de tecnologia de pagamentos que leve em conta o capital social dessas localidades; (2) as tecnologias hoje existentes para confecção de uma moeda social digital tendem a um ganho de escala que pode mostrar alguma incompatibilidade com pequenas comunidades onde o senso solidário é maior que o individual; (3) forçar a adoção de moedas sociais digitais em pequenas comunidades do tipo gemeinschaft pode eventualmente levar a um maior grau de individualização e à contratualização das relações interpessoais, dado que hoje muitas das relações nestas comunidades contêm alto grau de pessoalidade e informalidade; (4) havendo uma implementação de moedas sociais digitais de cima para baixo, este modelo tende a ser mais propício para experiências liberais focadas nos indivíduos do que para experiências comunitárias focadas no desenvolvimento do modelo pela própria comunidade. Como contribuição teórica, o estudo tenta mostrar o potencial do uso da teoria de Tönnies com o conceito de frames de Goffman.

Estudo da sinterização de eletrólito sólido de céria dopada com gadolínia

Fuel cells are electrochemical devices that convert chemical energy in electrical energy by a reaction directly. The solid oxide fuel cell (SOFC) works in temperature between 900ºC up to 1000ºC, Nowadays the most material for ceramic electrolytes is yttria stabilized zirconium. However, the high operation temperature can produce problems as instability and incompatibility of materials, thermal degradation and high cost of the surround materials. These problems can be reduced with the development of intermediate temperature solid oxide fuel cell (IT-SOFC) that works at temperature range of 600ºC to 800ºC. Ceria doped gadolinium is one of the most promising materials for electrolytes IT-SOFC due high ionic conductivity and good compatibility with electrodes. The inhibition of grain growth has been investigated during the sintering to improve properties of electrolytes. Two-step sintering (TSS) is an interesting technical to inhibit this grain growth and consist at submit the sample at two stages of temperature. The first one stage aims to achieve the critical density in the initiating the sintering process, then the sample is submitted at the second stage where the temperature sufficient to continue the sintering without accelerate grain growth until to reach total densification. The goal of this work is to produce electrolytes of ceria doped gadolinium by two-step sintering. In this context were produced samples from micrometric and nanometric powders by two routes of two-step sintering. The samples were obtained with elevate relative density, higher than 90% using low energy that some works at the same area. The average grain size are at the range 0,37 μm up to 0,51 μm. The overall ionic conductivity is 1,8x10-2 S.cm and the activation energy is 0,76 eV. Results shown that is possible to obtain ceria-doped gadolinium samples by two-step sintering technique using modified routes with characteristics and properties necessary to apply as electrolytes of solid oxide fuel cell

Estudo de pré-formulação para dose fixa combinada dos tuberculostáticos rifampicina, isoniazida, pirazinamida e etambutol (4 em 1)

According to the global framework regarding new cases of tuberculosis, Brazil appears at the 18th place. Thus, the Ministry of Health has defined this disease as a priority in the governmental policies. As a consequence, studies concerning treatment and prevention have increased. Fixed-dose combination formulations (FDC) are recognized as beneficial and are recommended by WHO, but they present instability and loss on rifampicin bioavailability. The main purpose of this work was to carry out a pre-formulation study with the schedule 1 tuberculosis treatment drugs: rifampicin, isoniazid, pyrazinamide and ethambutol and pharmaceutical excipients (lactose, cellulose, magnesium stearate and talc), in order to develop an FDC product (150 mg of rifampicin + 75 mg of isoniazid + 400 mg of pyrazinamide + 250 mg of ethambutol). The studies consisted of the determination of particle size and distribution (Ferret s diameter) and shape through optical microscopy, as well as rheological and technological properties (bulk and tapped densities, Hausner Factor, Carr s Index, repose angle and flux rate) and interactions among drugs and drug excipient through thermal analysis (DSC, DTA, TG and your derivate). The results showed that, except isoniazid, the other drugs presented poor rheological properties, determined by the physical characteristics of the particles: small size and rod like particles shape for rifampicin; rectangular shape for pyrazinamide and ethambutol, beyond its low density. The 4 drug mixture also not presented flowability, particularly that one containing drug quantity indicated for the formulation of FDC products. In this mixture, isoniazid, that has the best flowability, was added in a lower concentration. The addition of microcrystalline cellulose, magnesium stearate and talc to the drug mixtures improved flowability properties. In DSC analysis probable interactions among drugs were found, supporting the hypothesis of ethambutol and pyrazinamide catalysis of the rifampicin-isoniazid reaction resulting in 3- formylrifamycin isonicotinyl hydrazone (HYD) as a degradation product. In the mixtures containing lactose Supertab® DSC curves evidenced incompatibility among drugs and excipient. In the DSC curves of mixtures containing cellulose MC101®, magnesium stearate and talc, no alterations were observed comparing to the drug profiles. The TG/DTG of the binary and ternary mixtures curves showed different thermogravimetrics profiles relating that observed to the drug isolated, with the thermal decomposition early supporting the evidences of incompatibilities showed in the DSC and DTA curves

Sistema de gerência de informação de processos industriais via Web

The structure of Industrial Automation bases on a hierarchical pyramid, where restricted information islands are created. Those information islands are characterized by systems where hardware and software used are proprietors. In other words, they are supplied for just a manufacturer, doing with that customer is entailed to that supplier. That solution causes great damages to companies. Once the connection and integration with other equipments, that are not of own supplier, it is very complicated. Several times it is impossible of being accomplished, because of high cost of solution or for technical incompatibility. This work consists to specify and to implement the visualization module via Web of GERINF. GERINF is a FINEP/CTPetro project that has the objective of developing a software for information management in industrial processes. GERINF is divided in three modules: visualization via Web, compress and storage and communication module. Are presented results of the utilization of a proposed system to information management of a Natural Gas collected Unit of Guamar´e on the PETROBRAS UN-RNCE.

Análise da bacia hidrográfica do Rio Punaú-Rio Grande do Norte utilizando ferramentas de geoprocessamento

Provide data and information on watershed becomes important since the knowledge of their physical characteristics, land use, etcetera, allows for better planning and sustainable use of economically, socially and environmentally in this area. The investigation of the physical environment has been commonly given with the use of geoprocessing, which has proved a very efficient tool. Within this context, this research aims at analyzing the river basin Punaú (located in the cities of Touros, Rio do Fogo and Pureza, state of Rio Grande do Norte) in several aspects, using geoprocessing as a tool of work, to provide information about the entire watershed. Specifically, this study aimed to update pre-existing maps, such as geological, geomorphological and land use, generating map of environmental vulnerability, under the aspect of erosion susceptibility of the area, generating map of legal incompatibility, identifying areas that are already being employed in breach of environmental legislation; propose solutions to the occupation of the river basin Punaú, focused on environmental planning. The methodology was based on the use of geoprocessing tools for data analysis and to make maps of legal incompatibility and environmental vulnerability. For the first map was taken into account the environmental legislation regarding the protection of watersheds. For the vulnerability analysis, the generated map was the result of crossing the maps of geology, geomorphology, soils and land use, having been assigned weights to different attributes of thematic maps, generating a map of environmental vulnerability in relation to susceptibility to erosion. The analysis results indicate that agriculture is the most significant activity in the basin, in total occupied area, which confers a high degree of environmental vulnerability in most of the basin, and some agricultural areas eventually develop in a manner inconsistent with Brazilian environmental legislation. It is proposed to consider deploying a measure of revitalization of the watershed in more critical areas and conservation through mitigation measures on the causes of environmental degradation, such as protection of water sources, protection and restoration of riparian vegetation, protection of permanent preservation areas, containment of erosion processes in general, and others listed or not in specific laws, and even the establishment of a committee of basins in the area
