Toxoplasmosis is one of the most common zoonoses worldwide. The seroprevalence for T. gondii in human population from Brazil might range from 40 to 80%. The aim of this paper was to study the seroprevalence of T. gondii infection in children from age one to 15 living in a low socioeconomic community, named community of Jardim São Remo in the year of 2002. The community is located in the West ar...

We investigate whether corporations are following the “best disclosure practices” when presenting business reports on their Web sites. As a benchmark, we use the recommendations made by the Jenkins Committee (1994) to improve corporate reporting practices, to evaluate reports presented on corporate Web sites for their value, relevance, and quality of information. We compute a disclosure score u...

We have studied neural networks as models for time series forecasting, and our research compares the Box-Jenkins method against the neural network method for long and short term memory series. Our work was inspired by previously published works that yielded inconsistent results about comparative performance. We have since experimented with 16 time series of di ering complexity using neural netw...

introduction: glycemia and blood glucose levels are under the effect of hb a1c and therefore they could be considered as a valid index for the follow-up and control of diabetes .there are different and controversial reports on the effects of iron deficiency anemia on hb a1c. effects of ida in non diabetic patients are also unknown. the aim of the study was the comparison of hb a1c levels in hea...

The group method of data handling technique (GMDH) and Box-Jenkins methods are two wellknown time series forecasting of mathematical modeling. In this paper, we introduce a hybrid modeling which combines the GMDH method with the Box-Jenkins method to model time series data. The Box-Jenkins method was used to determine the useful input variables of GMDH method and then the GMDH method which work...

Solution and cell studies were performed to ascertain why individuals with hemoglobin (Hb) SC have disease whereas those with Hb AS do not. The polymerization of deoxygenated mixtures containing sickle cell Hb (Hb S; alpha 2 beta 2(6)Glu leads to Val) and Hb C (alpha 2 beta 2(6)Glu leads to Lys) was investigated by measurements of delay times and solubilities. In mixtures containing more than 4...
