A cidade de Ilha Solteira está propondo o projeto Conquista da Água, visando ao desenvolvimento sustentável do Município, a partir do turismo, da cultura e da ciência e tecnologia. Para atingir esse objetivo, os planejadores do meio físico-ambiental necessitam de dados que possam auxiliá-los na seleção dos melhores locais onde serão instalados as avenidas, o aeroporto e os demais espaços que comporão esse projeto. A elaboração do mapa de uso e cobertura do solo da área de interesse do projeto constitui um dos temas necessários ao banco de dados a ser utilizado pelos planejadores. Neste trabalho, é apresentado o estado de degradação dessa área, o que auxiliará na definição das estratégias de conservação ambiental.

Com o objetivo de se verificar a viabilidade econômica da cultura do melão, na região de Ilha Solteira, ano agrícola 1991/92, procedeu-se a uma análise econômica para estudar o comportamento de dois cultivares de melão Eldorado 300 e Valenciano Amarelo CAC, variando a adubação de cobertura, ou seja, utilizando-se 3 doses de N e de K2O: 2,5; 5,0 e 10,0 g/planta. O experimento foi irrigado através de um sistema de gotejamento, sendo que o investimento inicial para aquisição do material de irrigação para uma área de 1 ha, foi da ordem de US$ 11.500,00. Apesar do alto valor do investimento inicial, a cultura se mostrou altamente rentável. Com os resultados obtidos, verificou-se que todos os tratamentos apresentaram rentabilidade positiva, sendo que a maior receita líquida encontrada foi de US$ 4.048,00 do resultado econômico, gerado pela diferença entre a receita bruta e o custo total, recebe influência direta dos níveis de produtividade e do preço alcançado pelo produto.

Em fruticultura, existe hoje uma grande tendência de aumento da densidade de cultivo, procurando com isso uma maior produção por área. Pretendeu-se, neste trabalho, desenvolvido em Ilha Solteira-SP, estimar e analisar comparativamente o custo de produção e a lucratividade de bananeira-'Nanicão Jangada', sob duas densidades de cultivo: 1666 plantas (3,0mx2,0m) e 2500 plantas (2,0mx2,0m). Para o cálculo do custo, utilizou-se a estrutura do custo total de produção (CTP). Considerando os dois ciclos produtivos do bananal, o espaçamento de plantio mais adensado (com maior número de plantas por área) apresentou resultados econômicos mais satisfatórios que os obtidos para o cultivo menos adensado. A cultivar 'Nanicão Jangada' é uma alternativa de cultivo viável para a região de Ilha Solteira-SP.

The study carried out in the environment of Maracajaú reef an São Roque channel, had as main objective to analyze the characteristics of sediments active locally expressed in the grains, through collections of sediments in the field, technical processing and data analyzes of sediments. Data processing were made on three main aspects: biotic composition, concentration of calcium carbonate and particle size of the sediment. Differences between the sediments of the reefs and channel were observed. It was emphasized the contribution of algae limestone in the production of carbonate, with some influence of foraminifera near the coast. The particle size distribution presented significant results for the understanding of locally sedimentary deposits. The results showed an environment of carbonate, with predominance of algae limestone, associated to unconsolidated sediments with gross granularity, besides the presence of rhodoliths in all samples.The fragmentation of biotic components and the prevalence of elliptical rhodoliths with little or no branch, indicate an environment of high energy hydrodynamics. This work is a further contribution to the understanding of sedimentology active locally in reef environments, in particular the of Maracajaú reef, by virtue of their complex ecosystem composed of a diversity of wild fauna and flora that still little studied in Brazil comparing to accelerated growth of teeth extractions and usufructs of natural resources causing often irreversible impacts to the environment

The seismic reflection is used on a large scale in oil exploration. In case of marine acquisition the presence of high impedance contrast at the interfaces water/air generates multiple reflections events. Such multiple events can mask primary events; thus from the interpretational viewpoint it is necessary to mitigate the multiples. In this manuscript we compare two methods of multiple attenuation: the predictive multichannel deconvolution (DPM) and the F-K filtering (FKF). DPM is based in the periodicity of the multiples while FKF is based in multiples and primaries splitting in F-K domain. DPM and FKF were applied in common-offset and CDP gathers, respectively. DPM is quite sensible to the correct identification of the period and size of the filter while FKF is quite sensible to an adequate choice of the velocity in order to split multiples and primaries events in the F-K domain. DPM is a method that is designed to act over a specific event. So, when the parameters are well selected, DPM is very efficient in removing the specified multiple. Then DPM can be optimized by applying it several times, each time with a different parameterization. A deficiency of DPM occurs when a multiple is superposed to a primary event: in this situation, DPM can attenuate also the primary event. On the other hand, FKF presents almost the same performance to all multiples that are localized in the same sector of the F-K domain. The two methods can be combined in order to take advantage of their associated potentials. In this situation, DPM is firstly applied, with a focus in the sea bed multiples. Then FKF is applied in order to attenuate the remaining multiples

Tourism is an activity that uses the spatial objects and also produces and because it creates an economic activity areas for leisure. So for this to occur itdoes need a space reorganized, with infrastructure to receive visitors. And in the process of construction / reconstruction of tourist destination the state comes as a precursor, creating public policies that tourism can develop. Thus, this paper examines the transformation process by which the spaces are aiming to become tourist, and what changes occur in socio-spatial dynamic of the city in which this activity is inserted. The spatial area of study refers to the Alto de Santa Rita, Santa Cruz and the Isla de Santana Tourist Complex in Caicó both in Rio Grande do Norte. The reconstruction of the Island de Santana did not occur randomly, in order that the spatial changes were performed to meet the demand for which Caicó had to perform his greatest social and religious event, the Feast of Santana, which occurs since its colonization in year 1748 and also the Carnival these two events being considered as a strong tourist attraction of the city. And the Santa Rita High was built in order to enter the city of Santa Cruz in the script of religious tourism of the state through the devotion of the patron. The Dissertation isstructured in five parts, the first refers to the introduction of the work, while the second examines how tourism wound to the Rio Grande do Norte and internalizesthe third part deals with the spaces for tourism in these cities, the the fourthidentifies as the symbolism of these spaces influence the transformation and the latter reveals how these spaces affect the socio-economic structure of cities across the events

The growth of body proportions of Sardinella brasiliensis was not homogeneous in the study area, between Macaé (RJ) and Santa Catarina Island (SC); the growth rates (K) of the von Bertalanffy growth curve were greater than growth rates for another áreas. In this area the biomass estimates for pelagic fish is poor, and near Cabo Frio occurs an upwelling zone. These facts permit the sardines to attain large lengths in this area. Between Rio de Janeiro and Florianópolis the growth rates were lower than in the northern part and Paranaguá Bay. on the other hand the biomass estimates for pelagic fish in Rio de Janeiro-Florianópolis region was very high, and in this zone the population density is high and the growth rates are small. Paranaguá Bay is a particular region because of its geographical and oceanographic conditons; this is a shelter region with different features and the sardines living there attain small length. In this area the growth rates are intermediary among growth rates for fishes from Macaé-Cabo Frio and Rio de Janeiro-Florianópolis regions. Therefore, the growth rates for sardines in southeast Brazilian proves to be dependent of the population density, food and oceanographic conditions.

The aim of this work was to study the mite community associated to Genipa americana L., a native species used as urban tree in Ilha Solteira, São Paulo. For this, six plants of this species were sampled from January to December 2007 and 17 species belonging to 13 families were registered. Among these species, nine are predaceous, six are phytophagous, and two present unknown feeding habits. Predaceous Phytoseiidae presented the highest number of individuals (480) and species (3). Euseius citrifolius (Phytoseiidae) and Brevipalpus phoenicis (Tenuipalpidae) are the most frequent species. G. americana has potential as a reservoir of predatory mites, but its use in agroecosystems needs to be evaluated in further studies. Attention should be given to the fact that this is a host plant of B. phoenicis, an important pest species of mite.

O experimento foi conduzido em um solo Latossolo Vermelho Escuro álico, textura média, na Fazenda Experimental da UNESP - Campus de Ilha Solteira, SP. O trabalho teve como objetivo estudar o comportamento, da Galactia striata(Jacq.) Urb., quanto ao aspecto do valor nutritivo, em duas épocas de semeadura (28/09/79 e 25/03/80) e épocas de coleta (de 28 em 28 dias após emergência das plantas). O delineamento experimental foi em blocos casualizados com parcelas subdivididas, considerando as épocas de semeadura, as parcelas,e as épocas de coleta , as subparcelas. A aplicação de calcário se processou 30 dias antes de cada época de semeadura e a adubação fundamental na semeadura consistiu na aplicação de 20 kg/ha de nitrogênio na forma de sulfato de amônio(21% N), 120 kg de P2O5 na forma de cloreto de potássio (49,8% K). As semeaduras foram realizadas em linhas espaçadas de 0,30 m, com dez linhas de 5 m por subparcela, a uma profundidade de 2,5 cm, sendo deixada após o desbaste 10-15 plantas por metro linear. No material coletado separaram-se as folhas de hastes e efetuou-se a análise de digestibilidade in vitro da matéria seca. Conclui-se que: em função do decréscimo da digestibilidade in vitro da matéria seca por ser lento com o desenvolvimento vegetativo, a época de corte da Galactia striata pode ser determinada em função da produção de matéria seca. A Galactia striata é capaz de prover forragem de alto valor nutritivo, tanto no período de verão corno no de inverno.
