Objective: To evaluate the intraexaminer reproducibility of static anthropometric measurements of undergraduate dental students as well as the characteristics and regulating measurements of the dental stools used by them. Methods: Forty volunteers and 6 types of dental stools were evaluated. For the anthropometric measurements the employed equipments were: an adapted office chair, aflexible measuring tape with two adapted rods, a metallic device with a 90 degree central angle, string, a 35 x 24 cm rectangular wooden board, isolating tape and crepe tape. In order to standardize the position of the adapted office chair and the volunteers' feet, the floor was marked with the isolating and crepe tapes. A string was attached to the waist of each volunteer to mark the area corresponding to the kidney region making it possible to measure the seat-renal region area. The examined anthropometric measurements were height, trunkcephalic heigh, sacral-popliteal distance (OK?), hip width, popliteal height and the seat-renal region height. The evaluated characteristics of the dental stools relative to the seat were depth, horizontal width and minimum/maximum height. The back of the dental stool was evaluated as for the minimum/ maximum height adjustment. The anthropometric and dental stool measurements were obtained by a single examiner at two moments with a 1-week interval between the evaluations. Intra-class correlation coefficient (ρ) was used to estimate the intraexaminer reproducibility. Results: Excellent reproducibility was observed for all anthropometric measurements obtained (ρ=0.99) as well as for all dental stools evaluated (ρ=0.99). Conclusion: The method used to obtain the anthropometric and dental stools measurements was reproducible and can be used reliably.

An enhanced genetic algorithm (EGA) is applied to solve the long-term transmission expansion planning (LTTEP) problem. The following characteristics of the proposed EGA to solve the static and multistage LTTEP problem are presented, (1) generation of an initial population using fast, efficient heuristic algorithms, (2) better implementation of the local improvement phase and (3) efficient solution of linear programming problems (LPs). Critical comparative analysis is made between the proposed genetic algorithm and traditional genetic algorithms. Results using some known systems show that the proposed EGA presented higher efficiency in solving the static and multistage LTTEP problem, solving a smaller number of linear programming problems to find the optimal solutions and thus finding a better solution to the multistage LTTEP problem.

We study consistently the pion's static observables and the elastic and γ* γ → π0 transition form factors within a light-front model. Consistency requires that all calculations are performed within a given model with the same and single adjusted length or mass-scale parameter of the associated pion bound-state wave function. Our results agree well with all extent data including recent Belle data on the γ* γ → π0 form factor at large q2, yet the BaBar data on this transition form factor resists a sensible comparison. We relax the initial constraint on the bound-state wave function and show the BaBar data can partially be accommodated. This, however, comes at the cost of a hard elastic form factor not in agreement with experiment. Moreover, the pion charge radius is about 40 % smaller than its experimentally determined value. It is argued that a decreasing charge radius produces an ever harder form factor with a bound-state amplitude difficultly reconcilable with soft QCD. We also discuss why vector dominance type models for the photon-quark vertex, based on analyticity and crossing symmetry, are unlikely to reproduce the litigious transition form factor data. © 2013 Springer-Verlag Wien.

La edición número 99 de la revista Notas de Población destaca por la variedad de temas que se presentan en los seis artículos incluidos. En ellos se abordan cuestiones de relevancia para la investigación sociodemográfica en América Latina y el Caribe, que van desde las tendencias familiares y la edad en la primera unión y el primer hijo, hasta la migración de retorno, pasando por la información sobre las personas con discapacidad, los asentamientos precarios y las percepciones ambientales en áreas metropolitanas, entre otros.

O texto da Lei 9.795/99, que institui a educação ambiental e estabelece a Política Nacional de Educação Ambiental é uma resposta do Estado brasileiro aos anseios das comunidades tradicionais, que dependem diretamente dos recursos naturais, tais como indígenas, ribeirinhos e quilombolas. Este trabalho teve como objetivo central a identificação nessa Lei de interesses outros, que não só permeiam o texto como são mesmo predominantes. Para tanto, foi necessário analisar o texto da Lei como o ambiente propício para o conflito de interesses, aqui identificados como ideológicos e como esses interesses se manifestam na forma discursiva. A Lei foi estudada na particularidade de cada artigo a fim de detectar, em cada um, as escolhas linguísticas, a situação concreta de enunciação configurada e o discurso ideológico predominante. Houve preferência por formas nominais, aquelas com maior carga semântico-conceitual, inclusive em formas derivadas de processos verbais. Houve muita variedade na configuração da situação enunciativa, com predomínio do caráter imperativo, como em determinações e atribuições. No plano ideológico, propriamente dito, predominou o discurso conservador, vinculado ideologicamente aos interesses da classe dominante. Outro discurso bastante sentido no texto foi o reformista, próprio dos grupos mediadores dos conflitos entre dominantes e dominados. Uma vez que a Lei atende pouco ou nada aos interesses daqueles mais a aguardavam, conclui-se que a classe dominante consegue absorver as demandas sociais, mas transformando-as para seu próprio benefício. E visto que, por seus interesses serem postos na forma de lei, adquirem caráter universal e, como tal, é imposto para todos, como se fossem de todos, embora representem, de fato, apenas os interesses de alguns.
