Uso de SIG para identificar conflito do uso do solo na fazenda experimental da Embrapa Uva e Vinho em Bento Gonçalves, RS, Brasil: influência na rede de drenagens referentes as nascentes dos afluentes da bacia hidrográfica do rio Taquari-Antas.

The experimental farm of Embrapa Grape and Wine in Bento Gonçalves, state of Rio Grande do Sul, Brazil is part of the Taquari-Antas watershed is included in the Biosphere Reserve of the Atlantic. In this place develops activities occupying an area of ninety-four hectares. 67.34% of this area is covered by native forest and secondary vegetation, which were established as Legal Reserve Area (ARL) and Permanent Preservation Area (APP). The establishment of the drainage framework generated from the high-resolution digital elevation model (DEM), and native forest, were drawn APP (for permanent preservation areas) and legal reserve of rural property. The land cover conflict in the area of this farm regards to buildings near the areas of preservation are being framed in accordance with a proposal for preservation and restoration with native species. Through software SPRING 5.0.1, it was possible to carry by construction of georeferencing maps through crossing vectors for the land use conflicts analysis, the limits and the related drainage framework with APPs and RL with the identification of the springs. These data had been produced from high resolution aerialphoto image analysis, DEM generated from the aerial restitution and it is part of the data base image of the Laboratory of Remote Sensing and Geoprocessing - Embrapa Grape and Wine

Sustainable Viticulture: geotechnology for characterization of land use and identification of permanent preservation areas in the Serra Gaúcha, Brazil.

The Serra Gaúcha wine region is important for production of grapes and wines in Brazil and it is looking for recognition by geographical indications (GI) for wines. Environmental preservation is an important requirement to set a GI. In the research project developed by Brazilian Agricultural Research Corporation, one objective was to identify permanent preservation areas (PPA) in accordance with the Brazilian Forest Code and Environmental Laws. The geotechnologies were applied to identify the vineyards into PPA from high resolution aerial photographs to generate digital elevation model (DEM) and land use survey. The vineyards areas were obtained from the register of vineyards. From the intersection of vineyards and PPA, were identified the percentage of vineyards belonging to the GI located in the PPA. This work was identifying vineyards located in PPA areas within the Vale dos Vinhedos, Monte Belo and Pinto Bandeira GI. The studies were developed in the GIS laboratory of Embrapa Grape and Wine. First, were prepared the slope and distances maps and was elaborated the map of PPA, areas with slopes exceeding 47% and drainage, as well as the map of vineyards obtained by vectorization upon the aerial image. The map of conflict areas was generated by crossing the PPA and vineyards maps, showing vineyards deployed in conservation areas. The conflict area was characterized mostly by few vineyards deployed across drainage and the three GI areas showed a good preservation for the cultivation of the vine and the conflict areas must be converted in reclamation areas

Seascape connectivity of European anchovy in the Central Mediterranean Sea revealed by weighted Lagrangian backtracking and bio-energetic modelling

Ecological connectivity is one of the most important processes that shape marine populations and ecosystems, determining their distribution, persistence, and productivity. Here we use the synergy of Lagrangian back-trajectories, otolith-derived ages of larvae, and satellite-based chlorophyll-a to identify spawning areas of European anchovy from ichthyoplanktonic data, collected in the Strait of Sicily (Central Mediterranean Sea), i.e., the crucial channel in between the European and African continents. We obtain new evidence of ecosystem connectivity between North Africa and recruitment regions off the southern European coasts. We assess this result by using bio-energetic modeling, which predicts species-specific responses to environmental changes by producing quantitative information on functional traits. Our work gives support to a collaborative and harmonized use of Geographical Sub-Areas, currently identified by the General Fisheries Commission for the Mediterranean. It also confirms the need to incorporate climate and environmental variability effects into future marine resources management plans, strategies, and directives

Gender influence on professional satisfaction and gender issue perception among young oncologists. A survey of the Young Oncologists Working Group of the Italian Association of Medical Oncology (AIOM)

Background The professional gender gap is increasingly recognised in oncology. We explored gender issues perception and gender influence on professional satisfaction/gratification among young Italian oncologists. Methods Italian oncologists aged ≤40 years and members of the Italian Association of Medical Oncology were invited to participate in an online survey addressing workload/burnout, satisfaction in professional abilities and relations, relevant factors for professional gratification, and gender barriers. ‡ 2 test for general association or ‡ 2 test for trend was used to analyse the data. Results 201 young oncologists participated in the survey: 67% female, 71% aged 30-40 years, 41% still in training and 82% without children. Women and men were equally poorly satisfied by the relations with people occupying superior hierarchical positions. There was heterogeneity between women and men in current (p=0.011) and expected future (p=0.007) satisfaction in professional abilities: women were more satisfied by current empathy and relations with colleagues and were more confident in their future managerial and team leader skills. The most important elements for professional gratification indicated by all participants were, in general, work-life balance (36%) and intellectual stimulation/research (32%); specifically for women, work-life balance (48%) and intellectual stimulation/research (20%); and specifically for men, career (29%) and social prestige/recognition (26%). Heterogeneity within the same gender emerged. For example, the elements indicated by men as the most important were intellectual stimulation/research (39%) and work-life balance (21%) in general, versus social prestige/recognition (24%) and career (24%), respectively, specifically for men (p<0.0001). More women versus men perceived gender issue as an actual problem (60% vs 38%, p=0.03); men underestimated gender barriers to women's career (p=0.011). Conclusions Satisfaction in professional abilities varied by gender. Work-life balance is important for both women and men. Stereotypes about gender issues may be present. Gender issue is an actual problem for young oncologists, mostly perceived by women

A chromogenic chemosensor based on a complex of Di–Hydroxymethyl–Di–2–(Pyrrolyl)Methane and 7,7,8,8–Tetracyanoquinodimethane for the detection of captopril

Di–hydroxymethyl–di–2–(pyrrolyl)methane (DMPM) and 7,7,8,8–tetracyanoquinodimethane (TCNQ) were dissolved in acetonitrile to form a π–π charge–transfer complex, which exhibits a deep blue color. This complex is decomposed with the addition of captopril. It was possible to observe a change from the vivid blue color to pale orange–yellow, which is related to the formation of a new n–π complex between TCNQ and captopril. The formation kinetics of the complex between DMPM and TCNQ in acetonitrile was studied, it being concluded that the interaction between the two compounds is a photochemical process. Spectrophotometric titrations of TCNQ with DMPM were carried out and the results demonstrated that, in acetonitrile, the complex formed comprises one molecule of TCNQ for two of DMPM while in an acetonitrile:water mixture (9:1; v/v) a change to a 1:1 stoichiometry was observed.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Estruturação de banco de dados de imagens de satélite CBERS 2B das regiões vitícolas do Brasil, enfatizando o Vale do São Francisco, Região Nordeste.

The current paper present the remote sensing and geoprocessing application importance to obtain considerable datum related with brazilian grape production areas, specifying São Francisco River Valley, because this area is the principal tropical grape producer in Brazil, presenting, according IBGE 2002 estimation, close to 10% of total brazilian production, and is localizated between Casa Nova city, in Bahia state, and Santa Maria da Boa Vista and Lagoa Grande cities, in Pernambuco state. It was used CBERS-2B images, in his cameras CCD and HRC, acquired for free through a register in INPE?s website. The acquired images was processed with ENVI?s 4.2 help, objectiving to extract datum who are able to do a geographic characterization in the areas that was choosed, in this specific case, the grape culture expansion in São Francisco River Valley, who will be observed over the compare between the land use and cover maps generates by ENVI 4.2 and composed in SCARTA 4.3.3, and IBGE 2002 statistics. There is an idea to do an georeferencing orbital images data base, with all brazilian producers grape areas, and uses this information to heal some difficulties, and to contribute to follow the grape areas development and expansion, applying the agriculturand precision concept

M2-Branes and Fano 3-folds

A class of supersymmetric gauge theories arising from M2-branes probing Calabi-Yau 4-folds which are cones over smooth toric Fano 3-folds is investigated. For each model, the toric data of the mesonic moduli space is derived using the forward algorithm. The generators of the mesonic moduli space are determined using Hilbert series. The spectrum of scaling dimensions for chiral operators is computed.Comment: 128 pages, 39 figures, 42 table
