Abstract: Despite the absence of current official reports showing the number of cattle infected by rabies, it is estimated that nearly 30,000 bovines are lost each year in Brazil. In order to minimize the important economic losses, control of the disease is achieved by eliminating bat colonies and by herd vaccination. In this study, we compare the antibody response in cattle elicited by vaccination with an attenuated ERA vaccine (AEvac) and an inactivated-adjuvanted PV (IPVvac) vaccine. The antibody titers were appraised by cell-culture neutralization test and ELISA, and the percentage of seropositivity was ascertained for a period of 180 days. IPVvac elicited complete seropositivity rates from day 30 to day 150, and even on day 180, 87% of the sera showed virus-neutralizing antibody titers (VNA) higher than 0.5IU/ml. There were no significant differences between the VNA titers and seropositivity rates obtained with IPVvac in the two methods tested. AEvac, however, elicited significantly lower titers than those observed in the group receiving inactivated vaccine. In addition, the profiles of antirabies IgG antibodies, evaluated by ELISA, and VNA, appraised by cell-culture neutralization test, were slightly different, when both vaccines were compared.

Spatial Modeling of Soil Lime Requirements with Uncertainty Assessment Using Geostatistical Sequential Indicator Simulation  [PDF]
Jussara de Oliveira Ortiz, Carlos Alberto Felgueiras, Eduardo Celso Gerbi Camargo, Camilo Daleles Rennó, Manoel Jimenez Ortiz
Open Journal of Soil Science (OJSS) , 2017, DOI: 10.4236/ojss.2017.77011
Abstract: This work presents and analyses a geostatistical methodology for spatial modelling of Soil Lime Requirements (SLR) considering punctual samples of Cation Exchange Capacity (CEC) and Base Saturation (BS) soil properties. Geostatistical Sequential Indicator Simulation is used to draw realizations from the joint uncertainty distributions of the CEC and the BS input variables. The joint distributions are accomplished applying the Principal Component Analyses (PCA) approach. The Monte Carlo method for handling error propagations is used to obtain realization values of the SLR model which are considered to compute and store statistics from the output uncertainty model. From these statistics, it is obtained predictions and uncertainty maps that represent the spatial variation of the output variable and the propagated uncertainty respectively. Therefore, the prediction map of the output model is qualified with uncertainty information that should be used on decision making activities related to the planning and management of environmental phenomena. The proposed methodology for SLR modelling presented in this article is illustrated using CEC and BS input sample sets obtained in a farm located in Ponta Grossa city, Paraná state, Brazil.

Movimento , 2001,
Abstract: Nowadays, the prevalence of sleep disturbances in our environment is high. Insomnia is a very frequent complaint in the physician's offices, because of its important and close connection with other diseases, such as depression, anxiety, stress, affection problems, among others. The sleep disturbances have been more and more studied, as its repercussions affect not only the subject himself but all who surround him, by alterating his vitality, humor, performance and sociability. The goal of this work is to clarify and to update some aspects of function and auxiliar treatment of this disturbance by means of physical exercise, mainly evidencing the improvement of the quality of life of people who have this disturbance. This way, it's conclusive that physical exercise nowadays, is, without any doubt, part of the treatment of this disturbance, mainly evidencing relaxation, the effective improvement of the people involved in any oriented regular practice and the physiologic adaptations occurred coping with physical exercise, in a supposed better quality of life.
