AVALIAÇÃO DO EFEITO FUNGITÓXICO DE ÓLEOS ESSENCIAIS E HIDROLATOS EM DIFERENTES CONCENTRAÇÕES EM Colletotrichum gloeosporioides, AGENTE CAUSAL DA ANTRACNOSE DO MARACUJAZEIRO AZEDO (Passiflora edulis Sims) IN VITRO
O experimento foi instalado no Laboratório de Produção Vegetal do Campus Araquari.Após o isolamento do patógeno de folhas sintomáticas de maracujazeiro-azedo,obteve-se os hidrolatos e óleos essenciais de melaleuca, pitanga, citronela, limãocravo,losna e boldo, utilizando-se o método de hidrodestilação. A determinação dasconcentrações teve como base o quantitativo dos produtos destilados. Adotou-se umdelineamento experimental inteiramente casualizado, num fatorial 6x5 (plantas xconcentrações), em triplicata. A avaliação do crescimento micelial do Colletotrichumgloeosporioides nos tratamentos prosseguiu por 15 dias. Concluiu-se que os óleosessenciais de citronela e limão-cravo a partir de 5,0% inibiram o crescimento do fungo
FERTILIZANTE DE LIBERAÇÃO LENTA NA PRODUÇÃO DE MUDAS DE GALLESIA INTEGRIFOLIA (SPRENG.) HARMS
Este estudo objetivou comparar os efeitos de diferentes doses de fertilizante de deliberação lenta (FLL) no crescimento de mudas de Gallesia integrifolia, no município de Rio do Sul, SC. As sementes foram semeadas em tubetes de 180 cm³ utilizando como substrato-base uma mistura à base de casca de pinus, composto orgânico peneirado e vermiculita. O delineamento experimental foi inteiramente casualizado com seis tratamentos em quatro repetições, tendo 40 plantas como unidade experimental. As doses do FLL foram: T1 - 0 kg/m³, T2 - 2 kg/m³, T3 - 4 kg/m³, T4 - 6 kg/m³, T5 - 8 kg/m³ e T6 - 10 kg/m³. Ao final de 227 dias, foram avaliadas a altura (cm), diâmetro do colo (mm), biomassa fresca da parte aérea, biomassa seca da parte aérea e biomassa seca da raiz (g), biomassa seca total, relação altura e diâmetro e índice de Dickson. Mudas de Gallesia intergrifolia responderam positivamente ao uso do fertilizante de liberação lenta, apresentando melhores resultados de crescimento e padrões de qualidade sob doses entre 5,48 e 7,40 kg/m3.Palavras-chave: Fertilização de mudas.

Search for Supersymmetry with Gauge-Mediated Breaking in Diphoton Events with Missing Transverse Energy at CDF II
accepted to Phys. Rev. LettWe present the results of a search for supersymmetry with gauge-mediated breaking and \NONE\to\gamma\Gravitino in the +missing transverse energy final state. In 2.60.2 \invfb of collisions at 1.96 TeV recorded by the CDF II detector we observe no candidate events, consistent with a standard model background expectation of 1.40.4 events. We set limits on the cross section at the 95% C.L. and place the world's best limit of 149\gevc on the \none mass at $We present the results of a search for supersymmetry with gauge-mediated breaking and χ˜10→γG˜ in the γγ+missing transverse energy final state.

Measurements of branching fraction ratios and CP asymmetries in B+/- ->D_CP K+/- decays in hadron collisions
We reconstruct B+/- -> D K+/- decays in a data sample collected by the CDF II detector at the Tevatron collider corresponding to 1 fb-1 of integrated luminosity. We select decay modes where the D meson decays to either K- pi+ (flavor eigenstate) or K- K+, pi- pi+ (CP-even eigenstates), and measure the direct CP asymmetry A_CP+ = 0.39 +/- 0.17(stat) +/- 0.04(syst), and the double ratio of CP-even to flavor eigenstate branching fractions R_CP+ = 1.30 +/- 0.24(stat) +/- 0.12(syst). These measurements will improve the determination of the CKM angle gamma. They are performed here for the first time using data from hadron collisions.We reconstruct B±→DK± decays in a data sample collected by the CDF II detector at the Tevatron collider corresponding to 1 fb-1 of integrated luminosity.

Inclusive Search for Standard Model Higgs Boson Production in the WW Decay Channel using the CDF II Detector
We present a search for standard model (SM) Higgs boson production using ppbar collision data at sqrt(s) = 1.96 TeV, collected with the CDF II detector and corresponding to an integrated luminosity of 4.8 fb-1. We search for Higgs bosons produced in all processes with a significant production rate and decaying to two W bosons. We find no evidence for SM Higgs boson production and place upper limits at the 95% confidence level on the SM production cross section (sigma(H)) for values of the Higgs boson mass (m_H) in the range from 110 to 200 GeV. These limits are the most stringent for m_H > 130 GeV and are 1.29 above the predicted value of sigma(H) for mH = 165 GeV.We present a search for standard model (SM) Higgs boson production using pp̅ collision data at √s=1.96 TeV, collected with the CDF II detector and corresponding to an integrated luminosity of 4.8 fb-1.
