Resumo: A produção de leite de cabra no Brasil destaca-se no Nordeste, onde as condições de criação e os programas governamentais favorecem a produção. A qualidade higiênico-sanitária do leite de cabra, além de ser uma característica indispensável ao produto, exigida pela legislação Brasileira, contribui para diminuição nas perdas econômicas decorrentes da mastite e para a manutenção dos produtores na atividade. O Kit Embrapa de Ordenha Manual® para caprinos leiteiros é um conjunto de utensílios e práticas indispensáveis para a obtenção higiênica do leite de cabra, o qual apresenta-se como uma alternativa viável aos agricultores familiares devido à sua facilidade na utilização e baixo custo de aquisição. O Kit foi implantado e validado em 41 propriedades familiares, localizadas nos estados do Rio Grande do Norte, Paraíba e Ceará. Procedeu-se a coleta de leite de cabra 3 dias antes e 3 dias após a utilização do Kit, para a realização da Contagem Total de Bactérias (CTB). Observou-se uma redução média de 72% da CTB no leite produzido, e, 95% das propriedades adequaram-se à CTB exigida pela legislação Brasileira. [Effect of the use of the Milking Manual® EMBRAPA Kit for dairy goats total count in milk bacteria]. Abstract: The goat milk production in Brazil stands out in the Northeast, where the breeding conditions and government programs favor the production. The sanitary hygienic quality of goat milk as well as being an indispensable feature to the product, required by Brazilian law, contributes to decrease in economic losses resulting from mastitis and to the maintenance of the producers in the activity. The Embrapa manual milking kit® for dairy goats is an essential set of tools and practices for obtaining hygienic goat milk, which presents itself as a viable alternative to farmers due to its ease of use and low cost. The Kit has been deployed and validated in 41 family farms in the states of Rio Grande do Norte, Paraíba and Ceará. The goat milking practice was carried out both three days before and three days after using the kit for the realization of Total Bacteria Count (CTB). There was an average reduction of 72 % CTB on the milk, and 95 % of the properties have adapted to the CTB required by Brazilian law.

Among the industries, those that produce ceramic porcelain for use in construction industry and oil, during the exploration and production period, play an important role in the production of waste. Much research has been carried out both by academia and the productive sector, sometimes reintroducing them in the same production line that generated them, sometimes in areas unrelated to their generation, as in the production of concrete and mortar for the construction, for example, but each one in an isolated way. In this research, the aim is to study the combined incorporation of the waste drill cuttings of oil well and the residue of the polishing of porcelain, generated in the final stage of finishing of this product in a clay matrix, for the production of red pottery, specifically bricks, ceramic blocks and tiles. The clay comes from the municipality of São Gonçalo, RN, the drilling waste is from the Natal basin, in Rio Grande do Norte, and the residue of the polishing proceeds from a ceramic porcelain of the State of Paraíba. For this purpose, we used a mixture of a plastic clay with a non-plastic, in a ratio of 50% each, settling formulations with the addition of these two residues in this clay matrix. In the formulations, both residues were incorporated with a minimum percentage of 2.5% and maximum of 12.5%, varying from 2.5% each, in each formulation, which the sum of the waste be no more than 15%. It should be noted that the residue of the polishing of ceramic porcelain is a IIa class (not inert). The materials were characterized by XRF, XRD, TG, DTA, laser granulometry and the plasticity index. The technological properties of water absorption, apparent porosity, linear shrinkage of burning, flexural tensile strength and bulk density were evaluated after the sintering of the pieces to 850 °C, 950 °C and 1050 °C, with a burning time of 3 hr, 3 hr and 30 minutes, and 3 hr and 50 minutes, respectively, with a heating rate of 10 °C/minute, for all formulations and landing of 30 minutes. To better understand the influence of each residue and temperature on the evaluated properties, we used the factorial planning and its surfaces of response for the interpretation of the results. It was found that the temperature has no statistical significance at a 95% of reliability level in flexural tensile strength and that it decreases the water absorption and the porosity, but increases the shrinkage and the bulk density. The results showed the feasibility of the desired incorporation, but adjusting the temperature to each product and formulation, and that the temperatures of 850 °C and 950 °C were the one that responded to the largest number of formulations

The State of Paraíba is one of the most dynamic states of Brazil, strategically located in the northeast, is notable for the excellent potential for integration of different transportation modes forming the states of Rio Grande do Norte, Pernambuco and Alagoas. The dynamic that occurs with port activity causes changes in the space where it is installed. And the elements of this space are always more than suffering direct or indirect influences as the flow in the port is expanded. Therefore, this region became subject to the accidental spillage of oil, because it presents a heavy traffic of ships of various sizes that can run aground or collide with oil causing accidental events. The study of geomorphological and sedimentological compositions of seafloor becomes important as more is known about the relationships between these parameters and associated fauna, and can identify their preferred habitats. The database background, acoustically collected along the proposed study area, is a wealth of information, which were duly examined, cataloged and made available. Such information can serve as an important tool, providing a geomorphological survey of the sedimentary area studied, and come to subsidize, in a flexible, future decision making. With the study area Port of Cabedelo, Paraíba - Brazil, this research aimed to evaluate the influence of the tidal surface and background in modeling the seabed, including the acquisition of information about the location of submerged rocky bodies and the depth of these bodies may turn out to be natural traps for the trapping of oil in case of leaks, and obtain the relationship between types of bed and the hydrodynamic conditions present in the region. In this context, for this study were collected bathymetric data (depth) and physical oceanographic (height of water column, water temperature, intensity and direction of currents, waves and turbidity), meteorological (rainfall, air temperature, humidity, winds and barometric pressure) of the access channel to the Port of Cabedelo / PB and its basin evolution (where the cruise ships dock), and includes tools of remote sensing (Landsat 7 ETM +, 2001), so that images and the results are integrated into Geographic Information Systems and used in the elaboration of measures aimed at environmental protection areas under the influence of this scale facilities, serving as a grant to prepare a contingency plan in case of oil spills in the region. The main findings highlight the techniques of using hydroacoustic data acquisition together bathymetric surveys of high and low frequency. From there, five were prepared in bathymetric pattern of Directorate of Hydrography and Navigation - DHN, with the depth in meters, on a scale of 1:2500 (Channel and Basin Evolution of Access to Port of Cabedelo), where there is a large extent possible beachrocks that hinder the movement of vessels in the port area, which can cause collisions, running aground and leaking oil. From the scatter diagram of the vectors of currents, it can be seen as the tidal stream and undergoes a channeling effect caused by the bidirectional effect of the tide (ebb and flood) in the basin of the Port of Cabedelo evolution in NW-direction SE and the highest speed of the currents occurs at low tide. The characterization weather for the period from 28/02 to 04/07/2010 values was within the expected average for the region of study. The multidisciplinary integration of products (digital maps and remote sensing images), proved to be efficient for the characterization of underwater geomorphological study area, reaching the aim to discriminate and enhance submerged structures, previously not visible in the images

The present research deals with the modernization process of the Cidade da Parahyba2, between 1850 and 1924, and its relation with the cotton economy, which represented the main source of wealth accumulation for both the private and the public sectors throughout the First Republic. This study on urban history was developed by focusing on the understanding of the city s spatial formation, and despite its emphasis on the economic aspects involved, other factors that also contribute to the development of the social life were not put aside. The modernization process of the Cidade da Parahyba was also analyzed during the period established for the study according to a chronological and thematic approach that established comparisons with the financial situation of the State, whenever this was necessary, with special attention to the contribution of the cotton economy to the State´s revenues. It was possible to detect a lack of financial help and loans from the federal and municipal administrations for finishing several public works already underway in the capital, since the federal funds allocated to the State of Parahyba do Norte were rather employed in emergency works against droughts and in agricultural development. One can then conclude that the financial resources required for the urban interventions were withdrawn from the State s treasury itself, resources that were collected mainly from activities such as cotton exportation and cotton trading. Another factor shows the interdependence between the urban remodeling and the cotton economy: during the years marked by great droughts or by hard plagues on the cotton plantations, cotton production decreased, as well as the State s finances. The first measures taken by the State s administrators were to halt all projects of urban remodeling in progress in the Cidade da Parahyba, which was, clearly, the most privileged city by the State s presidents during the period analyzed. 2 The city of João Pessoa was named Cidade da Parahyba, a designation that remained until September 1930, when it received its present-day name in order to pay homage to the president of the State, João Pessoa Cavalcanti de Albuquerque, murdered in the city of Recife in August of that same year. At that time, the State of Paraíba was known as Parahyba do Norte. Since this work is limited to a period of time comprised within the First Republic, the names employed respect the terms used in those days

Este trabalho investigou o processo criativo do espetáculo Ethnotron-Ghetto Experiment, do Coletivo paraibano Tribo Éthnos, fundado na década de 1990 e ainda em atividade. A estratégia metodológica se dá através de estudos descritivos, valendo-se da teoria e prática de diversas linguagens artísticas presentes na obra apontada: artes visuais, performance, literatura e histórias em quadrinho; em ações realizadas pelo Coletivo ao longo dos anos, objetivando descrever e analisar o processo de criação do referido espetáculo de dança, através da minuciosa coleta de dados por meio de entrevistas abertas e semiestruturadas, e da pesquisa e captação de materiais audiovisuais. A Tribo Éthnos destaca-se na cena local na cidade de João Pessoa, e estadual, na Paraíba, visto que, nesse longo percurso de existência, além da preocupação em fundir muitas formas artísticas, bem como os artistas da Paraíba, aglutina pessoas que fazem arte em outros países e faz das danças urbanas algo instigante. A Tribo ainda preocupa-se com a troca de saberes através de palestras, oficinas, cursos e intercâmbios. A dissertação investiga o processo de criação dos artistas e, especificamente, dos dançarinos, utilizando-se principalmente do conceito de work in progress, proposto por Renato Cohen, e aplicado ao espetáculo estudado. Apresentam-se descrições dos movimentos coreográficos, do espetáculo de dança paraibano Ethnotron-Ghetto Experiment, de Dança de Rua da Era Funky, especificamente, com estilos como popping, waving, animation, strobing, floatine/ slidini, tiokine, trebing, breaking, waving, sliding, entre outros, visto serem estes parte integrante do processo de criação. Tais estilos remetem ao ilusionismo ou ao mimetismo, sugerindo, em seus movimentos truques, câmeras lentas, flutuações com os pés, entre outros. Segundo Valmir Vaz, o Coletivo, através do espetáculo, busca a integração dos corpos, procura uma libertação individual e sugere uma sensação de querer voar nas coreografias/cenas. Abordam-se os aspectos do processo criativo: o espaço cênico, o trabalho corporal, a sonoplastia e a roupa/indumentária. Trabalha-se o conceito do corpo virtual de José Gil no aspecto do corpo cênico

Caatinga is an important laboratory for studies about arthropods adaptations and aclimatations because its precipitation is highly variable in time. We studied the effects of time variability over the composition of Arthropods in a caatinga area. The study was carried out at a preservation area on Almas Farm, São José dos Cordeiros, Paraíba. Samples were collected in two 100 m long parallel transects, separated for a 30 m distance, in a dense tree dominated caatinga area, between August 2007 and July 2008. Samples were collected in each transect every 10 m. Ten soil samples were taken from each transect, both at 0-5 cm (A) and 5-10 cm (B) depth, resulting in 40 samples each month. The Berlese funnel method was used for fauna extraction. We registered 26 orders and the arthropods density in the soil ranged from 3237 to 22774 individuals.m-2 from January 2007 to March 2008, respectively. There was no difference between layers A and B regarding orders abundance and richness. The groups recorded include groups with few records or that had no records in the Caatinga region yet as Pauropoda, Psocoptera, Thysanoptera, Protura and Araneae. Acari was the most abundant group, with 66,7% of the total number of individuals. Soil Arthropods presented a positive correlation with soil moisture, vegetal cover, precipitation and real evapotranspiration. Increases in fauna richness and abundance were registered in February, a month after the beginning of the rainy season. A periodic rain events in arid and semiarid ecosystems triggers physiological responses in edafic organisms, like arthropods. Edafic arthropods respond to time variability in the Caatinga biome. This fauna variation has to be considered in studies of this ecosystem, because the variation of Arthropods composition in soil can affect the dynamics of the food web through time

Este estudo consistiu na análise estatística de dados de fluxos de metano durante a safra de 2004/2005 de cultivo de arroz sob regime de inundação contínua, em sistema de transplantio, com uso de fertilizante nitrogenado, na Estação Experimental da APTA/Pólo Regional de Desenvolvimento Tecnológico dos Agronegócios do Vale do Paraíba, em Pindamonhangaba/SP. Nove variáveis ambientais foram monitoradas ao longo desta safra. O principal objetivo do trabalho foi empregar Análise de Componentes Principais aos dados, visando encontrar combinações das variáveis que possam melhor explicar a influência de variáveis ambientais sobre os fluxos de metano, em comparação à análise de variáveis de forma isolada. A Análise de Componentes Principais identifica um pequeno número de combinações lineares (componentes principais) das variáveis que tenham máxima variância. Realizando esta análise através do software estatístico SAS (2002), foram obtidas nove componentes, sendo que a primeira poderia representar a variação de fluxos de metano em até 66%, enquanto as duas primeiras componentes juntas o representariam em até 85%..

The collection and conservation of the Cucurbita genus in Brazil happened in so dispersed institutions, an assessment of the storage conditions and the genetic diversity is needed, making it possible to identify new priorities for the genus. This work constitutes diagnosis of geographical distribution, storage conditions in situ and ex situ and on genetic diversity of the Cucurbita genus in Brazil. Research was done in herbariums, databases, literature and in situ (expeditions to rural areas and (markets) to map the areas of occurrence of the species. During these expeditions, questionnaires were applied to obtain information about the property and genus Cucurbita. Questionnaires were sent to 173 Brazilian institutions regarding the preservation conditions ex situ. A genetic variability of the Cucurbita genus was found in traditional Brazilian agriculture. Collections must be prioritized in the northern and southern regions (all states); the southeastern region, all states, except Minas Gerais; central-west, in Mato Grosso do Sul and Mato Grosso; the northeastern region, the states of Alagoas, Maranhão, Paraíba, Pernambuco, Piauí and Sergipe. Currently 5.545 entries are being conserved in the Germplasm banks, however, C. pepo, C. ficifolia, C. argyrosperma and wild species are poorly represented. The characterization level of conserved entries is low in the ex situcollections. Participative research projects must be financed as a way to stimulate the farmers to continue planting their local varieties. A coleta e conservação do gênero Cucurbita no Brasil aconteceu de forma dispersa pelas instituições, sendo necessário um diagnóstico sobre as condições de conservação e sobre a diversidade genética, tornando possível identificar novas prioridades para o gênero. Este trabalho realizou diagnóstico sobre distribuição geográfica, condições de conservação in situ e ex situ e sobre diversidade genética do gênro Cucurbita no Brasil. Para mapear as áreas de ocorrência das espécies, foram realizados levantamentos de informações em herbários, banco de dados, literatura e levantamentos in situ (expedições para áreas rurais, feiras livres e CEASAs). Nessas expedições foram aplicados questionários, buscando informações sobre a propriedade e o gênero Cucurbita. Em relação as condições de conservação ex situ, foram enviados questionários para 173 instituições brasileiras. Foi constatado que existe variabilidade genética do gênero Cucurbita na agricultura tradicional brasileira. Devem ser priorizadas coletas nas regiões Norte e Sul (todos os estados); região Sudeste, todos os estados, exceto Minas Gerais; região Centro-Oeste, no Mato Grosso do Sul e Mato Grosso; região Nordeste, os estados de Alagoas, Maranhão, Paraíba, Pernambuco, Piauí e Sergipe. Atualmente estão sendo conservados nos Bancos de Germoplasma 5.545 acessos, no entanto C. pepo, C ficifolia, C. argyrosperma e espécies silvestres estão pouco representadas. É baixa a taxa de caracterização dos acessos conservados nas coleções ex situ. Devem ser financiados projetos de pesquisa participativa como uma forma de estimular e dar condições aos agricultores de continuarem cultivado suas variedades locais.
