Procedimentos de Pesquisa em Geografia do Comércio e do Consumo e novas possibilidades de mapeamento. Análises a partir de Londrina (PR), Presidente Prudente (SP) e Ribeirão Preto (SP)

We aim to contribute to studies on the restructuring of the city with a focus on consumption. In the context where cities become the main place of action of man, a deep set of transformations has occurred. We are interested in understanding the redefinition of the logical production and appropriation of urban spaces for consumption of materials and services. For the analysis of delimitation of those commercial and service areas was made to compare the reality observed on the ground and indirectly through data acquisition and mapping obtained from the National Address List for Statistical Purposes, with the boundaries established by zoning and / or by municipal director plans of the cities studied, together with the classification of commercial establishments and in accordance with the standards of the National Classification of Economic Activities Services. We believe the importance of analyzing the process of concentration and dispersion of stores and / or services of Londrina (PR), Presidente Prudente (SP) and Ribeirão Preto (SP)...

Índices climáticos e infestação predial por larvas de Aedes aegypti (Linnaeus, 1762) e Aedes albopictus (Skuse, 1894) em Araçatuba-sp Brasil

Aedes is synanthropic; associated with climatic conditions and urban environment. This study performed a retrospective evaluation of the climatic indices and the A. aeypti and A. albopictus infestation larvae rates (IP), registered from the month of October, 2005 to 2009, in the Araçatuba city, São Paulo State. There was no variation in the average temperature in the period (26.3°C). The rain falls were high in 2005 (133.5 mm3 ) fell in 2006, 2007 and 2008 (55.0 mm3 , 78.5 mm3 and 79.0 mm3 , respectively) and increased in 2009 (104.0 mm3 ). The infestation IP was 1.10, 1.39, 0.36, 0.28 and 3.30, respectively in 2005, 2006, 2007, 2008 and 2009, none of them were A. albopictus larvae. There was no association between IP and temperature, but there was significant difference (P <0.001) between the IP of 2009, with the IP of 2007 and 2008. This study it was concluded that among the environmental factors just rain influenced the rate of larvae, "infestation", committed only by A. aegypti.

Análise sazonal e espacial da precipitação pluvial na bacia hidrográfica do rio Ivaí, Paraná

Climate variability and therefore the rainfall is often cited today, in times to speak of "global change", "global warming", "anthropogenic disasters," among other terms related to climate issues, which may cause floods and disasters that affect entire regions. In this sense, the seasonal rainfall and its extremes in the basin of Ivaí river, which has a drainage area of approximately 36 000 km2, covering a length of 680 km, located in the State of Paraná between coordinates 22 º 54'S 25 ° 44'S and 55 44'W to 52 º 42'W, were analyzed. Influence of rainfall for the man occupation is undeniably important, not less important is the role that this issue poses to the climate abiotic and biotic environment, because the dynamic relations between the fauna and flora is directly related to the availability of water in system (in this case, rain). The methodological procedures used during the research focused on statistical analysis of rainfall series daily, monthly and yearly, provided by the Superintendence of Water Resources Development and Environmental Protection Agency - SUDERHSA, an agency linked to the government of Parana. The analysis period chosen was from 1975 to 2005, with 38 stations for data collection, distributed evenly across the search area. The standard rainfall in the basin is explained mainly by convective processes in the summer (wet season) and front system causing more homogeneous rainfall over the basin (dry season). What is well marked is the occurrence of maximum rainfall in the years 1983 and 1997 (El Niño) and minimal in the years 1977, 1985 and 1988 (La Niña). Finally, although the study area have undergone a significant change in your landscape for over thirty years, this study indicates no significant interference in rainfall.

Classificação climática de Thornthwaite e sua aplicabilidade agroclimatológica nos diferentes regimes de precipitação em Pernambuco

Knowing the annual climatic conditions is of great importance for appropriate planning in agriculture. However, the systems of climatic classification are not widely used in agricultural studies because of the wide range of scales in which they are used. A series with data from 20 years of observations from 45 climatological stations in all over the state of Pernambuco was used. The probability density function of the incomplete gamma distribution was used to evaluate the occurrence of dry, regular and rainy years. The monthly climatic water balance was estimated using the Thornthwaite and Mather method (1955), and based on those findings, the climatic classifications were performed using the Thornthwaite (1948) and Thornthwaite and Mather (1955) for each site. The method of Kriging interpolation was used for the spatialization of the results. The study classifications were very sensitive to the local reliefs, to the amount of rainfall, and to the temperatures of the regions resulting in a wide number of climatic types. The climatic classification system of Thornthwaite and Mather (1955) allowed efficient classification of climates and a clearer summary of the information provided. In so doing, it demonstrated its capability to determine agro climatic zones.

Orange opals from Buriti dos Montes, Piauí: solid inclusions as genetic guides

As opalas laranjas de Buriti dos Montes (Piauí, nordeste do Brasil) têm propriedades gemológicas que favorecem seu uso como jóias; essas características incluem as cores, transparência, dureza e estabilidade relativamente elevadas. O exótico conteúdo de inclusões sólidas proporciona maior beleza às opalas da região. Essas opalas foram originadas por processos hidrotermais e são encontradas, principalmente, em vênulas e veios nos arenitos do Grupo Serra Grande, seccionados por soleiras e diques de diabásio da Formação Sardinha. Inclusões sólidas, tais como bolhas, agregados botrioidais, dendritos e nódulos, entre outras, consistem, principalmente, de caulinita, hematita/goethita e quartzo e influenciam a composição química das opalas. O zoneamento intenso dos cristais de quartzo e os elevados valores de Ba e Fe sugerem que os depósitos de opala foram formados em ambiente hidrotermal. Os diques de diabásio teriam sido responsáveis pelo aquecimento dos fluidos hidrotermais. Os arenitos, ricos em soluções aquosas, também teriam contribuído com a sílica disponível para a saturação dessas soluções e as fraturas permitiram a migração e aprisionamento dos fluidos hidrotermais, resultando nos veios mineralizados.

Identificação e caracterização de ambientes homogêneos de eventos de seca/umidade com base em simulações climáticas regionais

O objetivo deste trabalho foi identificar e caracterizar ambientes homogêneos com base na ocorrência de eventos de seca/umidade na Região Centro-Norte do Brasil, compreendendo os Estados de Rondônia, Mato Grosso, Goiás e Tocantins. Para esse fim, utilizou-se o índice quantitativo de seca denominado Anomalia de Umidade de Palmer (Z-index). Os dados climáticos de entrada utilizados por esse índice para quantificar os eventos de seca/umidade foram simulados pelo modelo regional climático RegCM3 ("Regional ClimateModel - version3"), para o período de 1975 a 1989. Por meio de análise de agrupamento foram identificados 13 ambientes homogêneos. Esses ambientes homogêneos foram caracterizados por meio da probabilidade de ocorrência de eventos de seca/umidade, densidade relativa destes eventos, variabilidade da precipitação pluvial anual e a probabilidade de ocorrência de seca na época das águas (outubro a maio). No Estado do Mato Grosso observou-se o maior número de ambientes homogêneos e na Região Sudoeste desse Estado, o ambiente 11, obteve a maior probabilidade de ocorrência de eventos extremamente seco, 9%. O ambiente 10, localizado no extremo leste de Goiás, teve a menor mediana para a precipitação pluvial anual. O evento climático com maior probabilidade de ocorrência na região de estudo é o próximo ao normal ou normalidade de umidade.

Survey of hearing disorders in an urban population in Rondonia, Northern Brazil

OBJECTIVE: To identify the prevalence of hearing loss for the population in the urban area. METHODS: A cross-sectional household survey based on the World Health Organization Ear and Hearing Disorders Survey Protocol was conducted in 298 households in the urban area of Monte Negro, Rondonia, Northern Brazil, from 2005 to 2007. Ear examinations, behavioral audiometry and pure tone audiometry were conducted on 577 individuals. RESULTS: The results showed that 3.8% (95%CI 2.17;5.45) of population were classifi ed in the disabling hearing impairment category. The prevalence of moderate hearing impairment was 3.4%; severe impairment was 0.4%; and profound hearing impairment was not found. CONCLUSIONS: The impairing hearing loss prevalence found in this study is within of the international prevalence for this level of hearing loss and smaller than observed in a previous study in the South region of Brazil.
