Georeferenced database generation with the purpose of hydrologic molding in reservoirs of the hydrographic basin of Jaguaribe river in the state of Ceará, Brazil

The edafoclimatic conditions of the Brazilian semiarid region favor the water loss by surface runoff. The state of Ceará, almost completely covered by semiarid, has developed public policies for the construction of dams in order to attend the varied water demand. Several hydrological models were developed to support decisive processes in the complex management of reservoirs. This study aimed to establish a methodology for obtaining a georeferenced database suitable for use as input data in hydrological modeling in the semiarid of Ceará. It was used images of Landsat satellite and SRTM Mission, and soil maps of the state of Ceará. The Landsat images allowed the determination of the land cover and the SRTM Mission images, the automatic delineation of hydrographic basins. The soil type was obtained through the soil map. The database was obtained for Jaguaribe River hydrographic basin, in the state of Ceará, and is applicable to hydrological modeling based on the Curve Number method for estimating the surface runoff.

Technical and economic indicators of the yellow passion fruit tree irrigated with underground water supply

The research aimed to quantify technical and economic indicators of yellow passion fruit tree irrigated with fractions of irrigation with underground source of water, to generate information that helps farmers in decision making on the implementation of investment in irrigated fruit growing (yellow passion fruit). For this purpose, we used the passion fruit crop irrigated with Microjet type irrigation system, with conducting system in simple espaliers. The treatments consisted of five hours of application of the depth of water required by the crop with irrigation frequency of two days. The results showed that the highest yield (16660kg ha-1) was obtained with the fractionation of irrigation twice a day (50% to 7h and 50% to 21h30), which provided an increase in productivity of 54%, demonstrating the financial viability and being highly profitable to the interest rate of 2% per year, with low sensitivity of financial risk to real interest rates above the prevailing market.

Sympaattisempaa, arvokkaampaa ja uniikimpaa: Kasettien julkaisutoiminta 2000–2010-luvun suomalaisessa underground-kulttuurissa

Tutkimuksen aiheena oli C-kasettien julkaisutoiminta 2000- ja 2010-luvun suomalaisessa underground-kulttuurissa. Tutkimuksen tavoitteena oli selvittää millaisena välineenä ja musiikkiformaattina kasettien julkaisijat kokevat kasetin. Lisäksi tarkasteltiin mitä kasettien julkaiseminen ja siihen liittyvät kokemukset kertovat tämän hetken suomalaisesta underground-kulttuurista. Tutkimuksessa haastateltiin neljää kasetteja julkaissutta henkilöä. Haastatteluista yksi oli parihaastattelu ja kaksi muuta olivat yksilöhaastatteluja. Metodologia oli hermeneuttis-fenomenologinen kenttätyö, jota laajennettiin Gilles Deleuzen ja Felix Guattarin muotoilemilla nomadismin ja rihmaston käsitteillä. Yksi työn päätavoitteista oli tutkia miten mannermainen filosofia sopisi yhteen empiiristen menetelmien kanssa. Tarkoituksena oli selvittää millaista tietoa mannermainen filosofia yhdessä kenttätyön ja etnografian kanssa antaisivat suomalaisesta underground-kulttuurista 2000- ja 2010-luvuilla. Tutkimuksessa selvisi, että underground-kasettien julkaisutoiminta 2000- ja 2010- luvuilla on ollut varsin vilkasta ja uusia kasetteja julkaistaan edelleen. Suurin osa kaseteista leviää underground-kulttuurin sisällä, joten ne eivät välttämättä päädy levykauppojen hyllyille. Kasettien julkaisemiseen löytyi monia syitä. Tärkeimmät näistä olivat taloudelliset tekijät ja eräänlainen eettinen nomadismi, joka tarkoittaa vallitsevien käytänteiden ulkopuolella toimimista. Kasettien julkaiseminen on halpaa ja tästä syystä se on mahdollista pienilläkin resursseilla. Kasettien julkaiseminen on myös väylä julkaista musiikkia ilman levy-yhtiöiden panostusta. Käytännössä mitä tahansa musiikkia voidaan julkaista kasettina. Kasettien painosmäärät liikkuvat korkeintaan muutamissa sadoissa nimikettä kohden. Tutkimusaiheena kasettien julkaisu osoittautui hyväksi alustaksi testata kenttätyön ja etnografian toimivuutta filosofisten teorioiden kanssa. Tutkimuksen edetessä osoittautui, että heideggeriläinen hermeneuttinen fenomenologia sekä Deleuzen ja Guattarin filosofia oli mahdollista saada toimimaan saman tutkimuksen sisällä. Niiden tarjoamat erilaiset ratkaisumallit eivät olleet toisiaan poissulkevia.

Analyzing hydraulic head of fluid flow in underground porous medium

Hydraulic head is distributed through a medium with porous aspect. The analysis of hydraulic head from one point to another is used by the Richard's equation. This equation is equivalent to the groundwater ow equation that predicts the volumetric water contents. COMSOL 3.5 is used for computation applying Richard's equation. A rectangle of 100 meters of length and 10 meters of large (depth) with 0,1 m/s fl ux of inlet as source of our fl uid is simulated. The domain have Richards' equation model in two dimension (2D). Hydraulic head increases proportional with moisture content.

Planktic Cyanobacteria from upper Tietê basin reservoirs, SP, Brazil

Considering the great ecological and sanitary importance of the cyanobacteria and the need of detailed information about these organisms in Brazilian water bodies, the present study aims at contributing towards the knowledge of the cyanobacterial flora of five reservoirs belonging to the upper Tietê Basin, São Paulo: Billings, Guarapiranga, Jundiaí, Pirapora, Ponte Nova and Taiaçupeba. In the past several years, these reservoirs have been submitted to severe environmental deterioration and have repeatedly presented cyanobacterial blooms, including those of toxic species. The samples were collected between 1997 and 2003 either with plankton net (20 µm mesh) or van Dorn's bottle, and preserved with lugol solution or formaldehyde. Some species were isolated and maintained in culture. Forty-eight species of cyanobacteria were identified, with predominance of the order Chroococcales (58%), followed by the orders Oscillatoriales (21%) and Nostocales (21%). Among the 48 studied species, 17 (35%) were considered potentially toxic. The occurrence and biodiversity of the cyanobacteria in each reservoir depend on the environmental conditions. Among the five water bodies, Billings Reservoir presented the most adequate situation for the development of a greater number of species (34), probably due to its high pH values (around 8). Pirapora Reservoir on the other hand, with highest conductivity (445.0 µS cm-1) and lowest Secchi depth values (0.2 m), presented the lowest cyanobacterial biodiversity (14 species).

Cyanobacterial occurrence and detection of microcystin by planar chromatography in surface water of Billings and Guarapiranga Reservoirs, SP, Brazil

Billings and Guarapiranga Reservoirs were deeply affected by environmental disturbances, which more evident consequence are the cyanobacterial blooms. Microcystins are the most common cyanotoxin in freshwaters and more than 70 types are known. Different methods for microcystins analysis in water can be used, among which ELISA and HPLC are the most frequently employed. However, less sophisticated and more economic methods can also be used. This is the case of planar chromatography (thin-layer chromatography) method previously used in cyanotoxins purification but gradually replaced by others. Posterior optimization of the microcystin chromatography conditions and because of its simplicity, rapidity, efficiency and low cost, this method is again considered an option for the analysis of microcystins and nodularins. Considering the importance of Billings and Guarapiranga Reservoirs for drinking water supplies and the few scientific data about cyanobacteria and cyanotoxins in these water bodies, the aims of this work are to analyze the biodiversity of cyanobacteria in the Billings and Guarapiranga Reservoirs and the detection of dissolved microcystins in the water. It was possible to identify 17 species of cyanobacteria, 9 of them being potentially toxic. In Billings Reservoir Microcystis aeruginosa (Kützing) Kützing and Cylindrospermopsis raciborskii (Woloszynska) Seenayya & Subba Raju are the most common species, while in Guarapiranga Reservoir only M. aeruginosa was considered as a common species. Microcystins were detected in all Billings Reservoir samples and in only one sample from Guarapiranga Reservoir.

Floristic surveys of aquatic macrophytes in reservoirs in the Agreste zone of Pernambuco State, Brazil

We surveyed the aquatic macrophytes in reservoirs in Camocim de São Félix in the Agreste zone of Pernambuco State, Brazil. Plants were collected on a bimonthly schedule from November/2008 to May/2009 in four reservoirs, and 33 taxa distributed among 23 families were encountered. The family Cyperaceae had the greatest number of species, followed by Lemnaceae. The predominant biologic form was emergent (33.3%) reflecting the extensive shorelines around the reservoirs analyzed.

Chromosome damage in underground coal miners: detection by conventional cytogenetic techniques and by submitting lymphocytes of unexposed individuals to plasma from at-risk groups

Chromosome abnormalities and the mitotic index in lymphocyte cultures and micronuclei in buccal mucosa cells were investigated in a sample of underground mineral coal miners from Southern Brazil. A decreased mitotic index, an excess of micronuclei and a higher frequency of chromosome abnormalities (fragments, polyploidy and overall chromosome alterations) were observed in the miners when compared to age-paired normal controls from the same area. An alternative assay for clastogenesis in occupational exposition was tested by submitting lymphocytes from non-exposed individuals to a pool of plasmas from the exposed population. This assay proved to be very convenient, as the lymphocytes obtained from the same individuals can be used as target as well as control cells. Also, it yielded a larger number of metaphases and of successful cultures than with common lymphocyte cultures from miners. A significantly higher frequency of chromatid gaps, fragments and overall alterations were observed when lymphocytes from control subjects were exposed to miner plasma pools. Control plasma pools did not significantly induce any type of chromosome alterations in the cultures of normal subjects, thus indicating that the results are not due to the effect of the addition of plasma pools per se.

A salvação pelo Rock: sobre a "cena underground" dos jovens evangélicos no Brasil

O rápido crescimento do "rebanho" evangélico, nas últimas décadas no Brasil, deve muito à surpreendente avidez com que grupos e indivíduos que participaram desse processo se apropriaram de tudo aquilo que, produzido para finalidades mundanas, mostrava-se evangelisticamente sedutor. Busca-se discutir neste artigo os problemas identitários que surgem nesse processo, atentando, especificamente, para a utilização da música "rock" por jovens evangélicos. Como conseguem instalar neste meio tal estilo musical, antes tão inaceitável às instituições representantes dessa modalidade de cristianismo? Como lidam identitariamente com práticas e atitudes que acompanham a cultura "rock and roll", como o sexo desregrado, consumo de drogas, rebeldia e, por vezes, alguma simpatia pelo satanismo? Que compósito identitário resulta desse inusitado encontro entre universos culturais aparentemente tão inconciliáveis?

'What ever happened to breakdancing?' : transnational b-boy/b-girl networks, underground video magazines and imagined affinities

In 1997, Paul Gilroy was able to write: "I have been asking myself, whatever happened to breakdancing" (21), a form of vernacular dance associated with urban youth that emerged in the 1970s. However, in the last decade, breakdancing has experienced a massive renaissance in movies (You Got Served), commercials ("Gotta Have My Pops!") and documentaries (the acclaimed Freshest Kids). In this thesis, 1 explore the historical development of global b-boy/bgirl culture through a qualitative study involving dancers and their modes of communication. Widespread circulation of breakdancing images peaked in the mid-1980s, and subsequently b-boy/b-girl culture largely disappeared from the mediated landscape. The dance did not reemerge into the mainstream of North American popular culture until the late 1990s. 1 argue that the development of major transnational networks between b-boys and b-girls during the 1990s was a key factor in the return of 'b-boying/b-girling' (known formerly as breakdancing). Street dancers toured, traveled and competed internationally throughout this decade. They also began to create 'underground' video documentaries and travel video 'magazines.' These video artefacts circulated extensively around the globe through alternative distribution channels (including the backpacks of traveling dancers). 1 argue that underground video artefacts helped to produce 'imagined affinities' between dancers in various nations. Imagined affinities are identifications expressed by a cultural producer who shares an embodied activity with other practitioners through either mediated texts or travels through new places. These 'imagined affinities' helped to sustain b-boy/b-girl culture by generating visual/audio representations of popularity for the dance movement across geographical regions.
