Episode of Low Level Jets in the north and northeast coast of state of Para: a case study of 2002 april 21st to 22nd

Neste estudo descreve-se as características da estrutura vertical de um episódio de Jatos de Baixos Níveis (JBN) ocorrido no litoral do Pará, utilizando-se para tal, dados das radiossondagens de Ajuruteua, Município de Bragança coletados durante o experimento DESMATA (Impacto do Desmatamento Junto ao Litoral Atlântico da Amazônia) realizado no período de 08 a 22 de abril de 2002. Dentre os casos detectados no período chuvoso, selecionou-se um que se manteve por 12 horas com velocidade média de 15m/s e que estava direcionado de Nordeste para Leste, no ponto de máxima velocidade. Os resultados observacionais indicaram que, este JBN localizado no litoral Paraense foi resultado da ação combinada de dois fatores: (1) oscilação inercial e (2) baroclinia superficial. Estes dois fatores combinados sustentaram este JBN com intensidades entre 10 e 13m/s durante o dia e entre 14 e 16m/s durante a noite, localizado a uma altitude média de 800m acima da superfície.

Peanut mechanized digging regarding to plant population and soil water level

The largest losses in mechanical harvesting of peanuts occur during the stage of digging, and its assessment is still incipient in Brazil. Therefore, the aim of this study was to evaluate the quantitative losses and the performance of the tractor-digger-inverter, according to soil water content and plant populations. The experiment was conducted in a completely randomized block design with a factorial scheme 2 x 3, in which the treatments consisted of two soil, water content (19.3 and 24.8%) and three populations of plants (86,111, 127,603 and 141,144 plants ha-1), with four replications. The quantitative digging losses and the set mechanized performance were evaluated. The largest amount of visible and total losses was found in the population of 141.144 plants ha-1 for the 19.3% soil water content. The harvested material flow and the tractor-digger-inverter performance were not influenced by soil water content and plant population. The water content in the pods was higher in 24.8% soil water content only for the population of 86,111 plants ha-1; the yield was higher in the populations of 141.144 and 127.603 plants ha-1, in the 19.3 e 24.8% soil water content, respectively.

Measurement of the ZZ production cross section and search for anomalous couplings in 2l2l' final states in pp collisions at root s=7 TeV

A measurement is presented of the ZZ production cross section in the ZZ -> 2l2l' decay mode with l = e, mu and l' = e, mu, tau in proton-proton collisions at root s = 7 TeV with the CMS experiment at the LHC. Results are based on data corresponding to an integrated luminosity of 5.0 fb(-1). The measured cross section sigma(pp -> ZZ) = 6.24(-080)(+0.86) (stat.)(-0.32)(+0.41) (syst.) +/- 0.14 (lumi.) pb is consistent with the standard model predictions. The following limits on ZZZ and ZZ-gamma anomalous trilinear gauge couplings are set at 95% confidence level: -0.011 < f(4)(Z) < 0.012, -0.012 < f(5)(Z) < 0.012, -0.013 < f(4)(gamma) < 0.015, and -0.014 < f(5)(gamma) < 0.014.
