PHYSICAL ACTIVITY PATTERNS OF ADOLESCENTS WITH LONG TERM ILLNESSES OR DISABILITIES IN FINNISH GENERAL EDUCATION
2014
Physical activity (PA) of adolescents with long term illnesses or disabilities (LTID) in general education is examined to provide evidence of PA levels from specific population groups. This study describes the PA levels of adolescents with LTID based on recommendations of daily 60mins of moderate-to-vigorous PA (MVPA) and vigorous leisure time PA (VPA) of at least two times a week for at least one hour per week. Finnish data from the Health Behaviour in School-aged Children (HBSC) study was pooled from 2002 and 2010 surveys. 1126 respondents (14.6%) self-reported as having a LTID and details of main categories of LTID were used to examine PA behaviours. Overall, 15.6% of adolescents with LT…
Nutrition, public health politics and dietary tools
2020
Abstract In order to ensure a good status of health through the diet, it is necessary to follow nutritional objectives that have been established according to the nutritional policies of each country. However, nutritional objectives will differ according to the specific population group and it would be necessary to have tools to estimate the nutritional status, anthropometrics, biochemical parameters, clinical examination, and dietary assessment being the main tools that are used. Dietary assessment tools are related to an appraisal of food and nutrient consumption as well as the dietary pattern of particular groups of people during a special period. Therefore this chapter aims to discuss t…
Age estimation using the radiographic visibility of the periodontal ligament in lower third molars in a Portuguese population.
2014
Objectives: The mineralization of third molars has been used repeatedly as a method of forensic age estimation. However, this procedure is of little use beyond age 18, especially to determinate if an individual is older than 21 years of age; thus, the development of new approaches is essential. The visibility of the periodontal ligament has been suggested for this purpose. The aim of this work was to determine the usefulness of this methodology in a Portuguese population. Study Design: Periodontal ligament visibility was assessed in the lower third molars, using a sample of 487 orthopantomograms, 228 of which belonging to females and 259 to males, from a Portuguese population aged 17 to 31 …
Study of Morphology of Reactive Dissolution Interface Using Fractal Geometry

J. Pharm. Sci. ISI Document Delivery No.: VF662 Times Cited: 7 Cited Reference Count: 15 Tromelin, A Gnanou, JC Andres, C Pourcelot, Y Chaillot, B; International audience; The determination of reactive fractal dimension was carried out using two forms of the Noyes-Whitney equation, -dQ/dt = K(Q/Q(0))(DR/3) and -d Q/dt = K' R(DR-3) using the Richardson plot on the basis of previous data obtained by dissolution of an orthoboric acid powder. The correlation of the results provided by the two ways of calculation allows proposal of the hypothesis that dissolution begins on a specific population of reactive sites and probably promotes the formation of microporous volumes or cracks.
