Avaliação de tratamentos alternativos para controle de diarreia em bezerros leiteiros.
O trabalho foi realizado no CPPSul, com objetivo de comparar o potencial do uso do complexo homeopático (Arsenicum, Podophyllum, China, Nux Vomica e Carbo vegetalis) ou do mineral (clinoptilolita) na prevenção de diarreia em bezerros lactentes.Editora técnica Claudia Cristina Gulias Gomes
Avaliação dos atributos quÃmicos de Latossolos em áreas de ocorrência da soja louca II na região oeste do Pará.
Anomalias em plantas relacionadas a solo são diretamente ligadas aos nÃveis crÃticos e tóxicos dos atributos fÃsico, quÃmico ou biológicos de solo, logo, a fertilidade do solo é um dos fatores de predisposição das plantas aos patógenos. A soja louca-II é uma anomalia que causa cerda 40% perdas em lavouras e sem causa definida. Objetivo do foi avaliar os teores e variância dos atributos quÃmicos de solos em áreas de com ocorrência da Soja Louca II. Realizaram-se 120 amostras a 20 cm de profundidas em áreas com e sem a ocorrência da anomalia em propriedades nos municÃpios de Santarém, Belterra e Mojui dos Campos na região oeste do Pará. Os Atributos quÃmicos Ph, P, K, Na, Ca, Mg, Al, Fe, Cu, Zn, Mn e CTC e Teor de Argila natural foram submetidos a análise descritiva e análise de variâncias no programa Biostat versão 5.3. Não foram encontras diferenças significativas entre os atributos nos tratamentos, sendo consideradas estatisticamente semelhantes as áreas com e sem ocorrência da Soja Louca II, porem com terrores de micronutriente em nÃveis tóxicos na maior parte das amostras em ambos os tratamentos
Assessment of the virulence of the Burkholderia mallei Strain BAC 86/19 in BALB/c Mice.
ABSTRACT - Burkholderia mallei is an aerobic, Gram-negative, non-motile bacillus. As an obligate mammalian pathogen, it primarily affects solipeds. Although rarely transmitted to humans, the disease it causes, glanders, is classified as a zoonosis. The bacterium was officially eradicated in Brazil in 1969; however, it reemerged after three decades. This study aims to assess the virulence of a specific B. mallei strain, isolated in Brazil, in BALB/c mice through intranasal infection. The strain, B. mallei BAC 86/19, was obtained from the tracheal secretion of a young mare displaying positive serology but no clinical signs of glanders. Post-mortem examinations revealed macroscopic lesions consistent with the disease, however. In mice, the LD50 was determined to be approximately 1.59 × 105 colony-forming units (CFU)/animal. Mice exposed to either 0.1 × LD50 or 1 × LD50 displayed transient weight loss, which resolved after three or five days, respectively. B. mallei persisted within the liver and lung for five days post-infection and in the spleen for seven days. These findings underscore the detectable virulence of the Brazilian B. mallei BAC 86/19 strain in mice, which are relatively resilient hosts. This research points to the importance of the continued investigation of the virulence mechanisms and potential countermeasures associated with B. mallei infections, including their Brazilian isolates
Observation of two new baryon resonances
Two structures are observed close to the kinematic threshold in the mass spectrum in a sample of proton-proton collision data, corresponding
to an integrated luminosity of 3.0 fb recorded by the LHCb experiment.
In the quark model, two baryonic resonances with quark content are
expected in this mass region: the spin-parity and
states, denoted and .
Interpreting the structures as these resonances, we measure the mass
differences and the width of the heavier state to be
MeV,
MeV,
MeV, where the first and second
uncertainties are statistical and systematic, respectively. The width of the
lighter state is consistent with zero, and we place an upper limit of
MeV at 95% confidence level. Relative
production rates of these states are also reported.Comment: 17 pages, 2 figure
Measurement of the lifetime
Using a data set corresponding to an integrated luminosity of ,
collected by the LHCb experiment in collisions at centre-of-mass energies
of 7 and 8 TeV, the effective lifetime in the
decay mode, , is measured to be ps. Assuming
conservation, corresponds to the lifetime of the light
mass eigenstate. This is the first measurement of the effective
lifetime in this decay mode.Comment: All figures and tables, along with any supplementary material and

Observation of an Excited Bc+ State
Using pp collision data corresponding to an integrated luminosity of 8.5 fb-1 recorded by the LHCb experiment at center-of-mass energies of s=7, 8, and 13 TeV, the observation of an excited Bc+ state in the Bc+π+π- invariant-mass spectrum is reported. The observed peak has a mass of 6841.2±0.6(stat)±0.1(syst)±0.8(Bc+) MeV/c2, where the last uncertainty is due to the limited knowledge of the Bc+ mass. It is consistent with expectations of the Bc∗(2S31)+ state reconstructed without the low-energy photon from the Bc∗(1S31)+→Bc+γ decay following Bc∗(2S31)+→Bc∗(1S31)+π+π-. A second state is seen with a global (local) statistical significance of 2.2σ (3.2σ) and a mass of 6872.1±1.3(stat)±0.1(syst)±0.8(Bc+) MeV/c2, and is consistent with the Bc(2S10)+ state. These mass measurements are the most precise to date
