Abstract:Geostatistics is the main technique used to efficiently determine spatial variability. The objective of this study was to evaluate the applicability of the principles of geostatistics in the use of semivariograms elaborated through parametric monitoring and the assumption automatically made by software in the map preparation of soil chemical attributes. Available phosphorus (P), potassium (K+), calcium (Ca2+), magnesium (Mg2+), base saturation (V%), sulfur (SO42-), and pH were compared from the soil chemical a… Show more
In order to meet the needs of the analysis and application of regression equation in clinical medicine of tonsil infection, this paper focuses on the semiparametric regression model method, cross-validation method, empirical method, and multiple regression equation analysis of atypical data using regression equation. The general method of analyzing this kind of data is given, and the parameter estimation and hypothesis testing of the model are systematically studied. The experimental results showed that among the 90 paraffin-embedded tissue specimens of chronic tonsillitis and adenoid hypertrophy in this study, 26 out of 49 male children were EBERs positive, accounting for 53.06% of male children (26/49 cases). 28 of the 41 female children were positive, accounting for 68.29 of the female children (28/41 cases). There were 14 cases in infant group, 20 cases in preschool age group, 25 cases in school-age group, and 31 cases in adolescence group; the EBERs-positive rate was 42.86% (6/14 cases) in early childhood and 55.00% in early school-age (11/20 cases), and the EBERs-positive rate was 60.00% in school-age group (15/20 cases) and 70.97% in adolescent group. The results showed that the latent infection rate of adenoid hypertrophy EBV in children with chronic tonsillitis showed no significant difference between genders. It is proved that the regression equation method can meet the needs of clinical analysis and application of tonsil infection.

A colheita é uma das principais etapas no ciclo produtivo, principalmente por poder influenciar na diminuição da produtividade do talhão, caso as regulagens da colhedora não estejam adequadas. Assim, esse trabalho visa avaliar as perdas qualitativas e quantitativas de colhedoras com trilha de fluxo radial e axial na cultura da soja, em função da variação da umidade do grão. Foram avaliadas duas colhedoras com dois diferentes sistemas de trilhas: uma axial; e outra radial. As umidades dos grãos colhidos se encontravam em duas situações: dentro da umidade recomendada; e não recomendada. Foram avaliadas as perdas quantitativas na pré-colheita, na plataforma segadora, na separação e limpeza e as perdas qualitativas pelo índice de danos mecânicos e pureza dos grãos. A perda quantitativa de grãos de soja pelo mecanismo de separação e limpeza é influenciada pelo sistema de trilha, sendo menor pelo uso da colhedora com trilha axial, independente do teor de umidade do grão de soja. Esse mesmo sistema de trilha também proporciona maior índice de pureza. A colhedora dotada com sistema de trilha radial proporciona maiores danos mecânicos aos grãos colhidos, sendo maiores quanto menor a umidade do grão de soja.
