No município de São José do Rio Preto (SP), o abastecimento de água tem sido realizado por meio da captação do rio Preto e afluentes e por poços existentes tanto no Sistema Aqüífero Bauru como no Botucatu/Pirambóia (Aqüífero Guarani). A água subterrânea responde por 70% do abastecimento local, sendo o Aqüífero Bauru o mais requisitado em virtude das boas condições que este apresenta como reservatório de água e também pela facilidade construtiva e operacional do poço tubular. A super explotação do aqüífero em questão se mostra cada vez mais acentuada, exigindo mais controle para sua exploração. O objetivo desta pesquisa foi avaliar alguns dos principais parâmetros hidráulicos, caracterizar o comportamento do fluxo subterrâneo e suas propriedades, propor condições necessárias para a construção de poços tubulares para captação de água subterrânea no Aqüífero Bauru, enfatizando a proteção sanitária, e, dessa forma, sugerir medidas adequadas para o gerenciamento dos recursos hídricos, como também para o auxílio ao Plano Diretor do município. Na análise conjunta dos parâmetros, importantes observações foram feitas a respeito da vulnerabilidade à contaminação do Aqüífero, servindo esta pesquisa não somente como uma referência para a análise de alguns parâmetros hidrogeológicos na área de estudo, mas também como apoio às medidas preventivas a serem praticadas por empreendimentos que podem, de forma direta ou indireta, estar interferindo na qualidade da água subterrânea do município de São José do Rio Preto (SP) / The population growth that has taken place in recent years has been the main reason for the increasing demand for water for public supply in the northwestern region of the state of São Paulo, Brazil. In the municipality of São José do Rio Preto, the water supply has drawn from the catchment of the Preto river and its tributaries, as well as from wells in the Bauru Aquifer and in the Botucatu/Pirambóia Aquifer (Guarani Aquifer). Ground water accounts for 70 percent of the local supply, with the Bauru Aquifer being the most resorted to due to its great capability as a water reservoir and the favorable conditions for building and operating a tube well. This aquifer has been increasingly over-exploited, and this situation requires tighter controls of its exploration. This study aimed at evaluating some key hydraulic parameters, describing the behavior of the underground flow and its properties, setting forth the required conditions for the construction of a tube well to catch underground water from the Bauru Aquifer with an emphasis on sanitary protection, and, therefore, suggesting appropriate measures for water resource management, as well as for supporting the municipality s Plano Diretor (Master Plan). The overall analysis of the parameters includes important observations on the aquifer s vulnerability to contamination. In this sense, this paper not only constitutes a reference work for the analysis of certain hydrogeological parameters in this field of study, but also supports preventive measures to be implemented by any agents that might be affecting, directly or indirectly, the quality of the underground water in the municipality of São José do Rio Preto.

The clown loach Chromobotia macracanthus, is a well known species in ornamental fish circuits although the knowledge about it in its wild environment today is limited. The outtake of 50 million juveniles every year may drive the population into a collapse and it might be necessary to breed clown loaches in captivity to lower the pressure in wild stocks. This has not yet been accomplished without hormone treatment. The aim of the present study is to find out if it is possible for C. macracanthus to prepare for spawning in captivity without the use of hormones. The study was set up according to documentation about the wild conditions simulating the migration prior to spawning from greater rivers and swamps to smaller streams upriver. Although the experiment did not result in spawning it is believed that egg production took place according to criteria for identifying sexually mature fish ready to spawn. If so it would have resulted in the fish retaining or reabsorbing the eggs since they were not laid. A surprising result which tells us it would not be unusual with egg production in C. macracanthus in aquariums around the world.

Orientador: Anderson Deo / Resumo: Este trabalho pretende discutir a implementação do trabalho decente e os Conselhos de Salários no Uruguai de 2005 a 2010. A hipótese principal consiste na incompatibilidade estrutural entre acumulação e equidade. Perguntamos se é possível superar a injustiça social, a desigualdade e implementar o trabalho decente por meio da negociação coletiva, aos moldes da OIT (1998). A abordagem teórica recai sobre as obras de Karl Marx e aos representantes da Teoria Marxista da Dependência. Theotônio dos Santos, Ruy Mauro Marini e Vivián Trías nos anos 1970 no intuito de explicarem o significado do caráter do desenvolvimento desigual e combinado e a superexploração do trabalho dos países latino-americanos abordaram os processos de extração de mais-valia em direção aos países desenvolvidos. Quando a Frente Ampla chegou à presidência da república no Uruguai criaram planos e programas de combate a fome e a extrema pobreza, reinseriram a política de Conselhos de Salários e implementaram o trabalho decente através do aumento salarial e proteção social aos trabalhadores. A resposta encontrada pelos investidores internacionais foi a inserção de novas tecnologias, a manutenção da existência de um exército industrial de reserva e a precarização laboral. / Abstract: This work aims to discuss the implementation of decent work and the Uruguayan Wage Councils from 2005 to 2010. The main hypothesis is the structural incompatibility between accumulation and equity. We ask whether it is possible to overcome social injustice and inequality and implement decent work through collective bargaining, along the lines of the ILO (1998). The theoretical approach is based on the works of Karl Marx and the representatives of the Marxist Theory of Dependence. Theotonio dos Santos, Ruy Mauro Marini and Vivián Trías in the 1970s to explain the meaning of the character of unequal and combined development and the overexploitation of labour in Latin American countries addressed the processes of extracting surplus value towards developed countries. When the Broad Front came to the presidency of the Republic in Uruguay, they created plans and programs to combat hunger and extreme poverty, reinserted the policy of Wage Councils and implemented decent work through wage increases and social protection for workers. The response found by international investors was the insertion of new technologies, the maintenance of the existence of an industrial reserve army and the precariousness of labor. / Résumé: Ce travail s’ occupe de discuter la mise em place du travail décent et les Conseils de Salaires au Uruguai de 2005 jusqu’à 2010.

MSCAGR ( Plant Production) / Many high valued tree species of medicinal significance in the Limpopo Province, South Africa exhibit seed dormancy, and also contain aromatic oils which inhibit rooting of their stem cuttings. These plant species are under pressure due to human over-exploitation. The main objective of this study was to investigate effects of rooting hormones on the rooting ability that will help in domesticating some of the selected high valued medicinal plants, Elaeodendron transvaalense (bushveld saffron), Brackenridgea zanguebarica (yellow peeling plane), and Warburgia salutaris (pepper-bark tree). Stem cuttings of these plant species were prepared and treated with various concentrations (500, 1000 and 2000 ppm) of IBA, IAA and NAA in different growth media (Natural soil, farm soil and hygromix) at a nursery house. 180 experimental units were sown and arranged in Randomized Complete Block Design (RCBD), each treatment replicated five times and then monitored for a period of three months. Data were only obtained from Brackenridgea zanguebarica as other species dried up two weeks after sprouting. The two variables measured from the experiments were sprouted stems and number of leaves. The data obtained were subjected to analysis of variance and least significant difference (LSD) at 5% probability level was used to compare treatment using STATISTICA software analysis package. The hormone, hormone concentration, growth media and their interactions had effect on sprouted stems and number of leaves produced on Brackenridgea zanguebarica cuttings, with no record of rooting ability. IBA (500 ppm and 1000 ppm) and control (without rooting hormone) showed high significant results with natural soil and farm soil in terms of leaf production compared to the hygromix, which is significantly lower from others. IBA at the various concentrations (500, 1000 and 2000 ppm) and the control gave the highest percentage sprouted stem on both natural soil and farm soil as compared with other hormones at the same / NRF

Conservation criminology as a derivative of environmental criminology is considered in this dissertation through a strategic/empirical investigation of the illegal exploitation of a cross-section of certain, essentially fiscally attractive marine resources, as a form of environmental crime in the Western Cape province. Through primarily qualitative and quantitative interviewing techniques, augmented by the application of a survey questionnaire, significant and pragmatic insight was obtained from knowledgeable functionaries. The study elucidates the purview and dynamics of the marine crime phenomenon by focussing specifically on issues such as modus operandi, crime scenes, causation, operational efficacy, and social/biological repercussions. Deficient policing capacity and concomitant lack of deterrence, compounded by institutional limitations, emerge as fundamental proclivities impeding proficient marine resource conservation. It is envisaged that this study will broaden the frontiers of marine crime knowledge, contributing not only to the implementation of effective mitigation programmes but also to enriching the criminological discipline as a whole. / Criminology / M.A. (Criminology)
