O estudo prévio de impacto de vizinhança e sua exigibilidade para o exercício do direito de construir quando da criação do condomínio edilício à luz da Constituição

O presente estudo objetiva sublinhar o estudo prévio de impacto de vizinhança como instrumento de política urbana apto a conformar a autonomia privada do incorporador imobiliário no exercício do direito de construir o condomínio edilício a legalidade constitucional. O que justifica o debate é a necessidade de harmonizar,numa sociedade de risco, a liberdade de construir o condomínio edilício à proteção e não degradação do meio ambiente urbano, gerenciando os riscos e planejando a utilização e fruição dos recursos ambientais, apresentando um instrumento de política urbana que alie a livre iniciativa do incorporador imobiliário e a preservação ambiental urbana como meta. Nestes termos segue o problema do presente estudo:qual é o instrumento de política urbana que pode conformar a autonomia privada do incorporador imobiliário no exercício do direito de construir o condomínio edilício à legalidade constitucional?Para responder esta indagação buscou-se: escorçar o histórico dos aspectos jurídicos e econômicos na produção do condomínio edilício; relacionar o princípio do numerus clausus e da tipicidade nos direitos reais para distinguir o condomínio edilício como tipo de direito real; identificar o espaço para fixação do conteúdo do condomínio edilício pelo incorporador imobiliário na viabilização, instituição e constituição; sublinhar a legalidade constitucional como um método hermenêutico; identificar as premissas metodológicas da legalidade constitucional; identificar os valores constitucionais que irradiam no exercício do direito de construir o condomínio edilício na cidade; distinguir a noção contemporânea de vizinhança; sublinhar a disciplina jurídica do estudo prévio de impacto de vizinhança; e identificar os conteúdos dos fatores de investigação do estudo prévio de impacto de vizinhança, relacionando-os com a construção do condomínio edilício. A pesquisa teve um enfoque quali-quantitativo no tratamento dos dados levantados em censos e relatórios de pesquisa, segundo amostras estratificadas e de acessibilidade do universo pesquisado, com a utilização do método de procedimento descritivo, tendo como delineamento as bibliografias e documentos concernentes ao tema. Os resultados revelaram que a construção do condomínio edilício pode causar impactos na vizinhança; que o estudo prévio de impacto de vizinhança é o instrumento de política urbana necessário para conformar a autonomia privada do incorporador imobiliário, no exercício do direito de construir o condomínio edilício, a legalidade constitucional; que para exigi-lo depende de regulamentação legal municipal; e que é baixa esta regulamentação dentre os Municípios brasileiros.

Memória e Representações Sociais de Práticas Religiosas de Matriz Africana

Esta dissertação de mestrado realizou um estudo sobre a identificação de memórias e representações sociais das práticas religiosas de matriz africana na população negra do bairro Dom Bosco situado no município de Juiz de Fora - MG. Foram entrevistados 60 sujeitos, de ambos os sexos, que se auto identificavam como negros, pardos, mulatos e outras denominações que caracterizam a ascendência negra. Através dos dados levantados na pesquisa concluímos que as representações sociais que esta população possui, são de que as práticas de matriz africana são demoníacas, feitiçarias para o mal e ações que causam prejuízo para as pessoas. As lembranças se mesclam com esquecimento, e as representações e memórias dos sujeitos da pesquisa estão associados com as práticas de sincretismo religioso existentes no Brasil. Os entrevistados não possuem lembrança dos líderes religiosos negros e nem dos locais de memória do bairro. Os participantes da pesquisa não se associam com estas práticas religiosas e têm em relação a elas uma visão de distanciamento e desinteresse. Constatamos que isto ocorre devido à dificuldade de aceitação pela sociedade em geral que as desvaloriza e discrimina, sempre atribuindo negatividade a elas e aos praticantes. Estas práticas são estereotipadas, folclorizadas e menosprezadas socialmente. O que faz com que a população afrodescendente não queira ser identificada com as tradições históricas, culturais e religiosos dos seus ancestrais

Mineração de dados para previsão de eventos extremos de precipitação

No presente trabalho foram desenvolvidos modelos de classificação aplicados à mineração de dados climáticos para a previsão de eventos extremos de precipitação com uma hora de antecedência. Mais especificamente, foram utilizados dados observacionais registrados pela estação meteorológica de superfície localizada no Instituto Politécnico da Universidade do Estado do Rio de Janeiro em Nova Friburgo RJ, durante o período de 2008 a 2012. A partir desses dados foi aplicado o processo de Descoberta de Conhecimento em Banco de Dados (KDD Knowledge Discovery in Databases), composto das etapas de preparação, mineração e pós processamento dos dados. Com base no uso de algoritmos de Redes Neurais Artificiais e Árvores de Decisão para a extração de padrões que indicassem um acúmulo de precipitação maior que 10 mm na hora posterior à medição das variáveis climáticas, pôde-se notar que a utilização da observação meteorológica de micro escala para previsões de curto prazo é suscetível a altas taxas de alarmes falsos (falsos positivos). Para contornar este problema, foram utilizados dados históricos de previsões realizadas pelo Modelo Eta com resolução de 15 km, disponibilizados pelo Centro de Previsão de Tempo e Estudos Climáticos do Instituto Nacional de Pesquisas Espaciais CPTEC/INPE. De posse desses dados, foi possível calcular os índices de instabilidade relacionados à formação de situação convectiva severa na região de Nova Friburgo e então armazená-los de maneira estruturada em um banco de dados, realizando a união entre os registros de micro e meso escala. Os resultados demonstraram que a união entre as bases de dados foi de extrema importância para a redução dos índices de falsos positivos, sendo essa uma importante contribuição aos estudos meteorológicos realizados em estações meteorológicas de superfície. Por fim, o modelo com maior precisão foi utilizado para o desenvolvimento de um sistema de alertas em tempo real, que verifica, para a região estudada, a possibilidade de chuva maior que 10 mm na próxima hora.

Trends and long-term variability of ocean properties at Ocean Station P in the northeast Pacific Ocean [abstract]

Twenty-seven years (1956-1983) of oceanographic data collected at Ocean Station P (50°N/145°W), as well as supplementary data obtained in its neighborhood, have been examined for trends and interannual variability in the northeast Pacific Ocean. There is evidence that the water is warming and freshening and that the isopycnal surfaces are deepening. Trends in oxyty are mostly not significant. The most common periods for the interannual variability appear to be 2 1/2 and 6-7 years. The vertical movement of water accounts for one half of the changes in temperature and salinity and 30% of those in oxyty. Other factors, such as a shift of water masses, may also be important.

北方农牧交错区土地利用（管理）方式对土壤氮素转化的影响

土壤氮素矿化是陆地生态系统氮素转化的重要组成部分。不同的土地利用（管理）方式会改变土壤氮素转化过程，影响土壤肥力的保持，进而可能造成土壤内氮素渗漏流失。为系统了解内蒙古农牧交错区土壤氮素转化的特点，本实验采用原位培养顶盖埋管法进行野外培养，每间隔一个月定期取样，于2004年7月-2006年10月在植物所恢复生态学实验站进行了两个试验，1：选择农牧交错区四种有代表性的土地类型（围封样地：FS，放牧样地：GS，弃耕地：AF，和农田：CF），比较土地利用方式之间氮素矿化的异同;2：在施肥样地通过不同施肥处理(F0: 1g N m-2, F1: 1g N m-2, F2: 2g N m-2, F3: 4g N m-2, F4: 8g N m-2, F5: 16g N m-2, F6: 32g N m-2, F7: 64g N m-2) 的土壤氮素转化动态，确定过度放牧的典型草原围封禁牧后，植被恢复过程中最适宜的施肥量。主要结论如下： 1. 与试验初期相比，整个非生长季围封样地、弃耕地和农田的铵态氮和无机氮含量逐渐降低，培养结束时铵态氮含量分别减少了67.04％，77.31％和70.54％，而放牧地的含量增加1.63％。围封样地、放牧地、弃耕地和农田的硝态氮含量分别增加了61.61%，376.43%，199.75%和133.16%。非生长季四种土地类型的土壤氮素转化速率主要受温度影响。围封样地、放牧地、弃耕地和农田非生长季矿化速率均值分别为-0.016，0.0429，-0.0051和-0.0030 μg g-1 d-1。硝化速率均值变幅为-0.43-0.17 μg g-1d-1。 2. 与没有冷冻而融化的土壤相比，冻融显著影响土壤无机氮含量的变化。只有在较低的土壤温度条件下冷冻以后，融化才会促进土壤氮素矿化。不同的冷冻时间长度下融化均会促进土壤硝化速率。土壤温度、土壤含水量变化是影响氮素转化速率的重要因子。 3. 四种土地类型的年日均矿化速率为放牧样地>农田>弃耕地>围封样地，分别为0.25，0.11，0.10，0.06μg g-1d-1，其年平均速率分别为11.65，5.50，5.00和2.46g m-2 y-1，而年日平均硝化速率分别为0.27，0.095，0.097和0.05μg g-1d-1。其中生长季日均矿化速率和日均硝化速率均为其年日均速率的两倍。因此，生长季形成的矿化氮是全年的93％，而形成的硝态氮占全年的86％。四种土地类型年均矿化氮的累积量平均为615.04 kg ha-1，而硝化作用的累积量变幅为230.44-1218.86 kg ha-1。四种土地类型的矿化速率和硝化速率的季节动态变化与气候因子的变化一致。 4. 不同施肥处理对典型草原土壤氮素转化均有显著影响。与对照相比，少量施肥（F1，F2）土壤铵态氮，硝态氮和无机氮含量分别减少20.57％，11.18％和17.18％。当施肥量大于F4（8g N m-2）时，随施肥量增加土壤铵态氮，硝态氮和无机氮含量增加18％-1191％。除F5（16g N m-2）外，与对照相比，随施肥量增加，土壤矿化速率增加了5-21倍。4 g N m-2 (F3)左右是典型草原生态系统比较合适的施肥量。 5. 氨气挥发速率的季节动态特征与气象因子的变化一致，其速率变幅为17.65 - 1228.39µg m-2 d-1，其中7月挥发量占全年的37％。与对照相比，少量施肥氨气挥发速率降低了1-2％，施肥量大于F3 (4g N m-2)，速率增加了1-4倍。实验期间总的流失量变幅为23.76-84.91mg m-2，而且通过氨气挥发流失量低于土壤全氮的3%。氨气挥发不是典型草原过量氮素流失的主要方式。 6. 氮素限制的典型草原，植被恢复过程中外源氮素添加阈值为：4 g N m-2 (F3)。与对照相比，短期施肥（3年）不会显著影响根系碳储量和土壤碳氮储量。施肥处理的土壤硝态氮和无机氮含量显著增加，说明施肥显著刺激硝化作用。典型草原60%植物根系主要分布在地下0-10cm，这里的碳储量占地下储量（0-50cm）的63%以上。随土壤深度增加，土壤全氮，全碳，无机氮储量降低。而铵态氮储量和可利用的无机氮含量随土壤深度增加，说明植物根系主要吸收利用上层可利用氮素，而且下层氮素矿化速率降低。

Shelf-life of rotary and solar tunnel dried SIS products under different packaging and storage conditions

A study was conducted on the shelf-life of rotary and solar tunnel dried SIS products under different packaging and storage conditions. Organoleptically dried products were found in good condition after a storage period of 60 days in ambient and chilled conditions. The moisture content, TVB-N value and bacterial load slightly increased during 60 days of storage in ambient and chilled conditions. The changes in moisture content and bacterial load were faster in ambient temperature than in chilled storage condition whereas changes in TVB-N value was higher in chilled condition than in ambient temperature. The initial moisture content was in the range of 13.71% to 22.84%. After 60 days of storage in ambient and chilled condition the moisture content of dried products was in the range of 15.09% to 25.11% and 14.49% to 25.01%, respectively. The initial TVB-N value was in the range of 10.64 to 17.52 mg/100g and after 60 days of storage in ambient and chilled condition, TVB-N value was in the range of 29.00 to 34.82 mg/100g and 31.41 to 39.11 mg/100g, respectively. The initial bacterial load was in the range of 1.91x10 super(8) to 2.84x10 super(8) and after 60 days of storage in ambient and chilled condition, the bacterial load was in the range of 6.2x10 super(8) to 1.8x10 super(9) and 5.75x10 super(7) to 5.05x10 super(8) CFU/g, respectively. The results of the present study indicated that it is necessary to store high quality dried products in sealed packed in chilled condition to ensure good quality up to a certain period of time.

An evaluation of a new product data model

Engineering companies face many challenges today such as increased competition, higher expectations from consumers and decreasing product lifecycle times. This means that product development times must be reduced to meet these challenges. Concurrent engineering, reuse of engineering knowledge and the use of advanced methods and tools are among the ways of reducing product development times. Concurrent engineering is crucial in making sure that the products are designed with all issues considered simultaneously. The reuse of engineering knowledge allows existing solutions to be reused. It can also help to avoid the mistakes made in previous designs. Computer-based tools are used to store information, automate tasks, distribute work, perform simulation and so forth. This research concerns the evaluation of tools that can be used to support the design process. These tools are evaluated in terms of the capture of information generated during the design process. This information is vital to allow the reuse of knowledge. Present CAD systems store only information on the final definition of the product such as geometry, materials and manufacturing processes. Product Data Management (PDM) systems can manage all this CAD information along with other product related information. The research includes the evaluation of two PDM systems, Windchill and Metaphase, using the design of a single-handed water tap as a case study. The two PDMs were then compared to PROSUS/DDM. PROSUS is the Process-Based Support System proposed by [Blessing 94] using the same case study. The Design Data Model is the product data model that includes PROSUS. The results look promising. PROSUS/DDM is able to capture most design information and structure and present it logically. The design process and product information is related and stored within the DDM structure. The PDMs can capture most design information, but information from early stages of design is stored only as unstructured documentation. Some problems were found with PROSUS/DDM. A proposal is made that may make it possible to resolve these problems, but this will require further research.

Identification and measurement of fatty acids, amino acids in roe of tuna fish (Thunnus tonggol) and its TVB and peroxide value during cold storage

The first aim of this research was to identify fatty acids, amino acids composition of Thunnus tonggol roe and their changes during cold storage (-18'C). The second aim was to determine the changes of moisture, protein, fat and ash contents of the roe during one year cold storage (-18'C). 60 samples of longtail tuna (Thunnus tonggol) ovaries were randomly collected form Bandar-e-Abbas landings. The samples were frozen at-30'C and kept in cold store at -18'C for one year. According to a time table, the samples were examined for identification of fatty acids, amino acids, moisture, protein, fat, ash, peroxide and T.V.N. and their changes were evaluated during this time. The results showed that 26 fatty acids were identified. The unsaturated fatty acids (UFA) and saturated fatty acids (SFA) were 62.33 and 37.6%, respectively, in fresh roe. So that, DHA (C22:6) and oleic acid (C18:1) had high amounts (24.79 and 21.88%) among the UFA and palmitic acid (C16:0) was the most content (22.75%) among the SFA. The PUFA/SFA was 0.91. Also, 17 amino acids were identified that essential amino acids (EAA) and nonessential amino acids (NE) were 10478 and 7562 mg/100g, respectively, and E/NE was 1.38. Among the EAA and NE, lysine (2110mg/100g) and aspartic acid (1924 mg/100g) were the most contents. Also, results showed that moisture, ash, protein and fat contents were 72.74, 1.8, 19.88 and 4.53%, respectively, in fresh roe. The effects of freezing and cold storage on the roes showed that UFA and SFA contents have reached to 49.83 and 48.07%, respectively, at the end of cold storage. It indicated that these compounds change to each other during frozen storage. Also, n-3 and n-6 series of fatty acids were 32.75 and 1.61% in fresh roe. But their contents decreased to 22.96 and 1.25% at the end of period. Among the fatty acids, 22:6 and C16:0 had the most changes. The changes of fatty acids were significantly at 95% level except for C15:1, C18:3(n-3) and C20:4(n-6). All of the amino acids decreased in frozen storage and their changes were significantly (P<0.05). EAA was 7818 mg/100g and E/NE was 1.27 at the end of storage period. Among the amino acids, leucine and lysine had the most changes. Moisture, ash, protein and fat contents were 70.13, 1.82, 19.4 and 6.51%, respectively, at the end of storage period. The peroxide value and T.V.N. increased during storage. So that, their contents have reached to 5.86 mg/kg and 26.37 mg/100 g, respectively, at the end of frozen storage. The best shelf life of Thunnus tonggol roe was 6 or 7 months, because of lipid oxidation and increasing of peroxide.

Economic value of the milkfish industry

A brief description is given of the milkfish (Chanos chanos) farming industry in the Philippines. Over the past 20 years, the relative importance of milkfish has declined with the expansion of tilapia, tiger shrimp and seaweed farming. In 1975, some 141,461 mt of milkfish made up 10% of the total fish production, whereas in 1995, the total milkfish harvest of 150,858 mt made up only 5.5% of the total fish production. Milkfish are harvested and marketed mostly fresh or chilled, whole or deboned, but some are canned or smoked. The domestic markets, mainly in Metro Manila, absorb most of the production. Milkfish is also absorbed in different product forms: dried, canned, smoked, or marinated. An export market for quick-frozen deboned milkfish fillets has begun to develop and fish processing companies are responding fast. The milkfish farming industry has important linkages with the various sectors that supply the inputs, and those that transport, store, market or process the harvest. For intensive milkfish farming to be both profitable and sustainable, more value-added products must be developed and marketed.

Compression techniques applied to multiple speech recognition systems

Speech recognition systems typically contain many Gaussian distributions, and hence a large number of parameters. This makes them both slow to decode speech, and large to store. Techniques have been proposed to decrease the number of parameters. One approach is to share parameters between multiple Gaussians, thus reducing the total number of parameters and allowing for shared likelihood calculation. Gaussian tying and subspace clustering are two related techniques which take this approach to system compression. These techniques can decrease the number of parameters with no noticeable drop in performance for single systems. However, multiple acoustic models are often used in real speech recognition systems. This paper considers the application of Gaussian tying and subspace compression to multiple systems. Results show that two speech recognition systems can be modelled using the same number of Gaussians as just one system, with little effect on individual system performance. Copyright © 2009 ISCA.
