Classificação climática para os municípios de botucatu e são manuel, sp

Abstract: 1 RESUMO A classificacao climatica procura definir os limites geograficos dos diferentes tipos de clima que ocorrem em todo mundo, sendo considerado um estudo basico para areas afins. Este trabalho teve como objetivo classificar climaticamente os municipios Botucatu (Fazenda Experimental do Lageado) e de Sao Manuel (Fazenda Experimental de Sao Manuel) ambas da Faculdade de Ciencias Agronomicas – UNESP, Campus de Botucatu, SP. Para tanto, utilizou-se das metodologias de Koppen e de Thornthwaite em dados normais de temperatura do ar e precipitacao pluviometrica no periodo de 36 anos (1971 a2006). Os municipios de Botucatu e de Sao Manuel tiveram a mesma classificacao climatica pelo metodo de Koppen, como sendo Cfa , clima temperado quente (mesotermico) umido, e a temperatura media do mes mais quente e superior a 22 oC. Pela classificacao de Thornthwaite houve uma pequena diferenca em funcao do indice de umidade, caracterizando como B 2 rB’ 3 a’ (clima umido com pequena deficiencia hidrica - abril, julho e agosto, mesotermico, com evapotranspiracao potencial anual de 945,15 mm e concentracao da evapotranspiracao potencial no verao igual a 33%) o municipio de Botucatu, e como B 1 rB’ 3 a’ (clima umido com pequena deficiencia hidrica - abril, julho e agosto, mesotermico, com evapotranspiracao potencial anual de994,21 mm e concentracao da evapotranspiracao potencial no verao igual a 33%) o municipio de Sao Manuel. UNITERMOS: temperatura do ar, precipitacao, evapotranspiracao, metodo de Koppen, metodo de Thornthwaite. CUNHA, A. R.; MARTINS, D. CLIMATIC CLASSIFICATION FOR THE DISTRICTS OF BOTUCATU AND SAO MANUEL, SP 2 ABSTRACT Climatic classification defines the geographical limits of different climate types all over the world, and it is considered essential to study similar areas. This work updates the climatic classification of the municipal districts of Botucatu and of Sao Manuel, State of Sao Paulo, where the experimental farms of the Schools of Agronomical Sciences - UNESP, Campus of Botucatu, State of Sao Paulo, are located. Koppen’s and Thornthwaite’s methods were used for the air temperature and precipitation data in a 36-year period (from 1971 to 2006). For both municipal districts of Botucatu and Sao Manuel, the climate was characterized as being Cfa, hot climate with rains in the summer and drought in the winter, and the average temperature in the hottest month is above 22 oC. According to Thornthwaite’s classification, there was a small difference due to the humidity index, characterized as B 2 rB' 3 a' (humid climate with small hydro deficiency - April, July and August, with annual potential evapotranspiration of 945.15 mm and concentration of the potential evapotranspiration in the summer of 33%) in the district of Botucatu, and as B 1 rB' 3 a' (humid climate with small hidric deficiency - April, July and August, with annual potential evapotranspiration of994.21 mm and concentration of the potential evapotranspiration in the summer of 33%)in the district of Sao Manuel. KEY WORDS: air temperature, precipitation, evapotranspiration, Koppen method, Thornthwaite method.

Anurans as prey: an exploratory analysis and size relationships between predators and their prey

Abstract: The vertebrate predators of post-metamorphic anurans were quantified and the predator–prey relationship was investigated by analysing the relative size of invertebrate predators and anurans. More than 100 vertebrate predators were identified (in more than 200 reports) and classified as opportunistic, convenience, temporary specialized and specialized predators. Invertebrate predators were classified as solitary non-venomous, venomous and social foragers according to 333 reviewed reports. Each of these categories of invertebrate predators was compared with the relative size of the anurans, showing an increase in the relative size of the prey when predators used special predatory tactics. The number of species and the number of families of anurans that were preyed upon did not vary with the size of the predator, suggesting that prey selection was not arbitrary and that energetic constraints must be involved in this choice. The relatively low predation pressure upon brachycephalids was related to the presence of some defensive strategies of its species. This compounding review can be used as the foundation for future advances in vertebrate predator–prey interactions.

Search for dark matter and large extra dimensions in monojet events in pp collisions at √s = 7 TeV

Abstract: A search has been made for events containing an energetic jet and an imbalance in transverse momentum using a data sample of pp collisions at a center-of-mass energy of 7 TeV. This signature is common to both dark matter and extra dimensions models. The data were collected by the CMS detector at the LHC and correspond to an integrated luminosity of 5.0 inverse femtobarns. The number of observed events is consistent with the standard model expectation. Constraints on the dark matter-nucleon scattering cross sections are determined for both spin-independent and spin-dependent interaction models. For the spin-independent model, these are the most constraining limits for a dark matter particle with mass below 3.5 GeV, a region unexplored by direct detection experiments. For the spin-dependent model, these are the most stringent constraints over the 0.1-200 GeV mass range. The constraints on the Arkani-Hamed, Dimopoulos, and Dvali model parameter MD determined as a function of the number of extra dimensions are also an improvement over the previous results.

Measurement of the inclusive W and Z production cross sections in pp collisions at √s = 7 TeV with the CMS experiment

Abstract: A measurement of inclusive W and Z production cross sections in pp collisions at sqrt(s)=7 TeV is presented. The electron and muon decay channels are analyzed in a data sample collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 36 inverse picobarns. The measured inclusive cross sections are sigma(pp-> WX) B(W-> l nu) = 10.30 +/- 0.02 (stat.) +/- 0.10 (syst.) +/- 0.10 (th.) +/- 0.41 (lumi.) nb and sigma(pp -> ZX) B(Z-> l^+l^-) = 0.974 +/- 0.007 (stat.) +/- 0.007 (syst.) +/- 0.018 (th.) +/- 0.039 (lumi.) nb, limited to the dilepton invariant mass range 60 to 120 GeV. The luminosity-independent cross section ratios are [sigma(pp->WX) B(W-> l nu)]/[sigma(pp-> ZX) B(Z->l^+l^-)] = 10.54 +/- 0.07 (stat.) +/- 0.08 (syst.) +/- 0.16 (th.) and [sigma(pp->W^+X) B(W^+ -> l^+nu)] / [sigma(pp->W^- X) B(W^- -> l^- nu)] = 1.421 +/- 0.006 (stat.) +/- 0.014 (syst.) +/- 0.029 (th.). The measured values agree with next-to-next-to-leading order QCD cross section calculations based on recent parton distribution functions.

Search for the standard model Higgs boson decaying into two photons in pp collisions at s=7TeV

Abstract: A search for a Higgs boson decaying into two photons is described. The analysis is performed using a dataset recorded by the CMS experiment at the LHC from pp collisions at a centre-of-mass energy of 7 TeV, which corresponds to an integrated luminosity of 4.8 inverse femtobarns. Limits are set on the cross section of the standard model Higgs boson decaying to two photons. The expected exclusion limit at 95% confidence level is between 1.4 and 2.4 times the standard model cross section in the mass range between 110 and 150 GeV. The analysis of the data excludes, at 95% confidence level, the standard model Higgs boson decaying into two photons in the mass range 128 to 132 GeV. The largest excess of events above the expected standard model background is observed for a Higgs boson mass hypothesis of 124 GeV with a local significance of 3.1 sigma. The global significance of observing an excess with a local significance greater than 3.1 sigma anywhere in the search range 110-150 GeV is estimated to be 1.8 sigma. More data are required to ascertain the origin of this excess.
