Estudaram-se o efeito de diferentes tipos de embalagens e a ação do dióxido de enxofre (SO2) na conservação pós-colheita de uvas finas de mesa var. Crimson Seedless e Itália. Os frutos, colhidos em propriedade agrícola situada no município de Boa Vista-RR (Lat. 2º 50' 06 N e Long. 60º 40' 28 W), apresentavam, no momento da colheita, sólidos solúveis (SS) médios de 16,50 e 14,80°Brix, para as variedades Crimson Seedless e Itália, respectivamente. Antes da confecção dos tratamentos, os cachos foram higienizados em solução de hipoclorito de sódio (NaOCl) a 100 mg.L-1, previamente acidificada, por dez minutos. Utilizaram-se, para a atmosfera modificada passiva, sacolas de polietileno de baixa densidade (PEBD), sem perfuração, com 0,010; 0,015 e 0,020mm de espessura,e acondicionadas em embalagens secundárias de papelão (4kg) e de madeira (7,5kg). Para a geração do SO2, foram utilizados papéis Kraft de liberação rápida, com 3 e 8g de metabissulfito de sódio (Na2S2O5). Após a confecção dos tratamentos, os frutos foram armazenados em câmara frigorífica a 4 ± 1°C e 95 ± 3% de umidade relativa (U.R.). As avaliações foram realizadas no momento da colheita e, 7; 21; 35; 42 e 56 dias de armazenamento refrigerado, quanto à porcentagem de perda de massa fresca, taxa de desgrana e de bagas deterioradas, qualidade do engaço e teor de SS dos frutos. Após oito semanas, foi realizado teste de preferência para as duas variedades. Verificou-se, em ambas as variedades, que as uvas submetidas à ação do gerador de SO2 , contendo 3g de metabissulfito de sódio e acondicionamento em embalagens de PEBD de 0,020mm de espessura, independentemente do tipo de embalagem secundária, apresentaram a menor perda de massa fresca, menor taxa de desgrana e de bagas deterioradas, e melhor qualidade do engaço. Os resultados da análise sensorial concordaram com os resultados das análises físico-químicas. Não foram detectadas diferenças nos teores de SS entre os tratamentos, em ambas as variedades.

O estudo objetivou o estabelecimento de um método efetivo e satisfatório do controle do dano de frio em limas-ácidas. Os frutos colhidos no município de Boa Vista-RR, 140 e 150 dias após a floração, apresentaram valores médios de 7,9 e 8,2 ºBrix; 6,3 e 6,0 mL de ácido cítrico.100mL de polpa-1 e pH de 2,8 e 3,0, respectivamente, nas duas colheitas. Após cada colheita, os frutos foram levados ao laboratório de Fitotecnia/UFRR, onde foram selecionados, limpos e submetidos aos tratamentos: T1 - controle; T2, T3 e T4 - condicionamento a 35ºC, por 6, 12 e 24 horas, respectivamente; T5 - aquecimento intermitente a 20ºC, por 8 horas, após 5 e 10 dias a 1ºC; T6 - aquecimento intermitente a 20ºC, por 8 horas, após 10 e 20 dias a 1ºC; T7 - ethephon a 1.500 mg.L-1; T8 - ethephon a 3.000 mg.L-1. Os tratamentos T9 ao T16, diferenciaram-se dos tratamentos T1 a T8, apenas, na data da colheita (10 dias após a primeira). O experimento foi avaliado a cada 15 dias, durante 75 dias, a 1 ± 0,5 ºC e 92 ± 5 % de UR, quanto ao dano de frio, aspecto visual, perda de massa fresca, sólidos solúveis (SS), acidez titulável (AT), SS/AT (ratio - RT), clorofila total e ácido ascórbico. O atraso na colheita não proporcionou efeito significativo algum. Todos os tratamentos, à exceção do controle e do aquecimento intermitente aos 10 e 20 dias, foram eficientes no controle do dano de frio. No entanto, o tratamento químico e o condicionamento térmico aceleraram precocemente o metabolismo dos frutos, principalmente no que concerne à perda de massa fresca e ao aspecto visual. O maior teor de clorofila total e de ácido ascórbico, bem como o melhor aspecto visual, a não-incidência de podridões e a menor perda de massa fresca foram detectadas nos frutos submetidos ao aquecimento intermitente aos 5 e 10 dias. Os SS, AT e RT estavam dentro dos padrões de qualidade e não variaram estatisticamente entre os tratamentos.

Besides being considered the greatest pests of fruit growing, fruit flies constitute a large obstacle to the growth of the exportation of fresh fruit. Knowledge of the structure of fruit fly communities is of great importance to the bioecological studies of these insects, but there is a lack of information about the faunistic composition of fruit flies in Brazil. The objective of this work was to analysis the composition of the species of Anastrepha, in eleven mango orchards of the fruit growing complex Gaviao River, Bahia, Brazil. These studies were done in 2004 and 2005, in Anage, Caraibas and Belo Campo town, 23 McPhail traps, which collected 798 female fruit flies from the genus Anastrepha. The structure of these communities was evaluated in each orchard by means of faunistic indexes frequency, constancy, dominance, diversity and similarity. The number of species varied from four to eight in each orchard; and the following species was recorded: Anastrepha fraterculus (Wiedemann), Anastrepha obliqua (Macquart), Anastrepha dissimilis Stone, Anastrepha amita Zucchi, Anastrepha distincta Greene, Anastrepha pickeli Lima. Anastrepha sororcula Zucchi and Anastrepha zenildae Zucchi. The most frequent and dominant species were A. fraterculus and A. obliqua. The indexes of diversity varied from 1.01 to 1.62. In general, the similarity between orchards was high (above 55.0%). We observed the formation of groups, one constituted by Frutvale, Carlan, Santa Clara and Panorama orchards; another composed of Cofet, Campo Gaviao and Ouro Verde and a third group formed by Boa Vista orchard. Barra da Onca and Arruda are distinguished from other orchards.

A short time after the creation of the first Geology courses in Brazil (in 1957 with the pioneers in the University of São Paulo and in the Federal Universities of Ouro Preto, Pernambuco and Rio Grande do Sul, and then in the following year in the Federal Universities of Bahia and Rio de Janeiro), there arose other initiatives that spread almost twenty Geology courses throughout Brazil. In addition to expanding the Geology teaching in the South, Southeast and Northeast regions, these initiatives succeeded in allowing access to geological education for the population in the North and Central-west of Brazil. In the 1960s, the courses in the Federal University of Para in Belém (1964), University of Brasilia (1965) and São Paulo State University in Rio Claro (1969) were implanted. In the following decade, the courses in the Federal Rural University of Rio de Janeiro in Seropédica (1970), the Federal University of Ceará in Fortaleza (1970), the University of Rio dos Sinos in São Leopoldo (1973), the Federal University of Paraná in Curitiba (1973), the Federal University of Minas Gerais in Belo Horizonte (1973), the Federal University of Amazonas in Manaus (1976), the Federal University of Mato Grosso in Cuiabá (1976), the Federal University of Rio Grande do Norte in Natal (1976), and the State University of Rio de Janeiro in Rio de Janeiro (1977) were all created. At the close of the twentieth century, the course was implanted in the State University of Campinas (1998). Now, at the beginning of the twenty-first century, new Geology courses are being implanted, accentuating the movement inland of Geology teaching in Brazil. The Federal University of Pará began a new course in its campus in Marabá in the south-east of Pará and the Federal University of Bahia implanted a new course in its campus in Barreiras in the west of Bahia. Finally, the Federal Universities of Sergipe, Espírito Santo and Roraima commenced Geology courses in Aracaju, Alegre and Boa Vista, respectively. This chapter will present the synthesis of the Geology courses which, over the last decades of the twentieth century, contributed to the expansion of Geology teaching in the country, taking it to every region and giving opportunities to a large number of Brazilian citizens to realize their dreams and tread the paths of their professional vocation.

Given the intense expansion of the industries in Brazil and the discovery of hydrocarbons in the pre-salt layer of the Santos and Campos Basin, there is a need to expand the distribution of oil and gas network in the country. The present work aims to present the development of susceptibility map by two distinct methods of two events (debris flows and full wave), applied to the establishment of pipelines on Ribeirão da Prata Basin. The research area covers two municipalities: São João da Boa Vista and Águas da Prata, in total 145 km2. In the paper was used the methodology proposed by Zaine (2011) for the physiographic subdivision method, which uses geological maps, geomorphological maps, digital terrain models and aerial photographs, used to extract the main elements of the physical environment, as rivers, lines, ridges, tops forms and valley forms and historical processes. Thus, the basin was divided into 11 physiographic zones, considering the following elements: thickness of soil, rock type, geomorphology, amplitude, ridges orientation, erosion occurences and mass movements. Were subsequently performed location maps of dams, that had as main purpose to localize major dams in the study area along with their area and perimeter of the reservoir, and land use map that subdivided the area in woody vegetation, permanent culture, temporary culture and urban area. Along with the preparation of the auxiliar maps was conducted a field campaign with three days and approximately 2 points per km2, which aimed to better understand the physical environment and check the main peculiarities of the study area. Criteria have been established for susceptibility maps physiographic subdivision and land use, and a survey of criteria weights used in each map for both processes under study. For the preparation of susceptibility maps were adopted two different methods, which treat the weighted average and the multiplicand. The weighted average method it is...

The current concern with environmental issues by the scientific community, governmental and civil society also brings out the need to recover, preserve and conserve the environment. With this understanding, this work was prepared, which had as one of the main objectives of the historical process of land use and occupancy of the Pontal, since the nineteenth century to the present day. From this, the changes were evident in the types of land use, which rose from native forest to plant crops (permanent and temporary crops) and later as pasture. Through this process of occupation, exploitation of forests and replacement even three, Reserves being brought from the Far West Paulista, through the state government of Sao Paulo, they were almost decimated. Such areas decreed by law to be preserved and conserved, with the rampant occupations, were suffocated by the fakes and illegal occupation of land tenure contracts, leaving the region currently only a few forest fragments and protected areas of State Park Morro do Diabo, PRNP Boa Vista and Ecological Station Black Lion Tamarin. Furthermore, the article emphasizes the main legislation being developed by federal and state levels aimed at protecting natural resources and the effectiveness they had with the passage of time, demonstrating that the conservation of the environment, has several contributions in the law, however, and they are so vast that hinder its application.
