Introduction: The current Brazilian legislation states that health services must be performed by the Specialized Service of Safety Engineering and Labor Medicine (SESMT). Objective: To analyze the dental and medical reasons for absenteeism, checking the interference of factors such as age, gender and position of the worker, and most of the reasons that led the employee to miss work. Material and methods: The research appears as a descriptive study with a quantitative approach. The dental and medical certificates and statements of attendance were analyzed, duly approved, lodged in a acrylic industry in the city of Araçatuba-SP, from January to July 2011. Results: Of the total number of certificates (n = 1841), only 103 (5.6%) were for dental reasons. Predominance of the age group of 20-29 years, males and with non-administrative function. The reasons most dental and medical certificates stated that led the workers to miss working days were "inclusive and impacted teeth" and "diarrhea and gastroenteritis of presumed infectious origin", respectively. As to factors related to absenteeism, there was a severity index of 2.83, 1.33 frequency and average duration of absences of 2.12. Conclusions: It is concluded that dental reasons had little weight on total absences due to illness that caused the temporary leave of the worker for a shorter period. The age and function variables influence the occurrence of work absenteeism.

Objetivou-se com este trabalho avaliar os efeitos de uma dieta de alto nível de energia e proteína combinada com a aplicação de bST no perfil de expressão dos genes da leptina e de seu receptor Ob-Rb no parênquima mamário de novilhas leiteiras. Foram utilizadas amostras de parênquima mamário de 32 novilhas holandesas distribuídas aleatoriamente em quatro tratamentos (n=8): dieta com alto ou baixo teor de energia e proteína combinada ou não com a aplicação de bST. O delineamento utilizado foi em blocos casualizados com arranjo de tratamentos em esquema fatorial 2 × 2. A extração do RNA total das amostras de tecido foi feita e o nível de expressão gênica foi analisado por qRT-PCR utilizando-se o gene da glicuronidase β como controle, pelo método 2-ΔΔCt. Animais que receberam a dieta com alto conteúdo de energia e proteína apresentaram maior expressão de mRNA de leptina, com aumento de 56%, e menor expressão de mRNA do receptor Ob-Rb, com redução de 18%. Por outro lado, a aplicação de bST resultou em diminuição da expressão do mRNA de leptina e do receptor Ob-Rb em 74% e 23%, respectivamente. Não houve interação entre dieta e aplicação de bST. O aumento na expressão de leptina pode explicar, ao menos em parte, os efeitos negativos da dieta de alta energia e proteína, oferecida no período pré-púbere, sobre a produção de leite de novilhas leiteiras.

A correlated two-body basis function is used to describe the three-dimensional bosonic clusters interacting via two-body van der Waals potential. We calculate the ground state and the zero orbital angular momentum excited states for Rb-N clusters with up to N = 40. We solve the many-particle Schrodinger equation by potential harmonics expansion method, which keeps all possible two-body correlations in the calculation and determines the lowest effective many-body potential. We study energetics and structural properties for such diffuse clusters both at dimer and tuned scattering length. The motivation of the present study is to investigate the possibility of formation of N-body clusters interacting through the van der Waals interaction. We also compare the system with the well studied He, Ne, and Ar clusters. We also calculate correlation properties and observe the generalised Tjon line for large cluster. We test the validity of the shape-independent potential in the calculation of the ground state energy of such diffuse cluster. These are the first such calculations reported for Rb clusters.
