Development and evaluation of a hypermedia system that integrates basic concepts of mechanics, biomechanics and human anatomy
Flavia Rezende,Marco Antonio Cavalcanti Garcia,Cláudio dos Santos Dias Cola
Investiga??es em Ensino de Ciências , 2006,
Abstract: This work describes the modeling of a hypermedia learning system (called “Biomec”) that integrates physical, biomechanical and anatomical concepts involved in the human motion and a study carried out with undergraduate students who interacted with the system. The instructional design of the “Biomec” hypermedia system was developed on the basis of a theoretical framework which articulates the Cognitive Flexibility Theory and the interdisciplinary approach to knowledge. The system was evaluated based on its use by students of Biomechanics I and Kinesiology in a Pre Service Teachers Training Course of Physical Education aiming to discuss the following questions: (i) what is its impact on the students’ attitude related to Physics? (ii) in what extent does the hypertextual approach to the content favor the interdisciplinary conception of human motion? (iii) in what extent do the students’ navigation profiles adapt to conceptual needs of the different disciplines of the course? The students answered instruments that assessed affective and cognitive aspects before and after the interaction with the system, and had their navigation registered and analyzed. The set of data obtained allowed to conclude that the “Biomec” system is a relevant instructional material, capable of positively influence the students’ attitude related to Physics, to favor the interdisciplinary approach of human motion and to attend the students enrolled in Biomechanics I better than the students enrolled in Kinesiology.

Jornal Brasileiro de Pneumologia , 2011, DOI: 10.1590/S1806-37132011000200011
Abstract: objective: to analyze the cytological findings of ct-guided percutaneous fine-needle aspiration biopsies of the lung, to demonstrate the diagnostic feasibility of the method in the investigation of pulmonary lesions, and to determine the complications of the procedure, evaluating its safety. methods: a retrospective analysis of 89 patients with various types of pulmonary lesions who underwent 97 procedures over a period of five years. the patients were divided into groups regarding the indication for the procedure: suspicion of primary lung cancer (stages iiib or iv); suspicion of lung cancer (stages i, ii, or iiia) and clinical contraindications for surgery; suspicion of pulmonary metastasis from other organs; and pulmonary lesions with benign radiological aspect. all of the procedures were performed with 25-gauge needles and were guided by spiral ct. the final diagnosis was confirmed by surgical biopsy and clinical/oncological follow-up. for the analysis of complications, the total number of procedures was considered. results: the main indication for the procedure was suspicion of advanced-stage primary lung cancer. the accuracy of the method for malignant lesions was 91.5%. the lesion was confirmed as cancer in 73% of the patients. the major complication was pneumothorax (27.8%), which required chest tube drainage in 12.4% of the procedures. conclusions: the principal indication for ct-guided fine-needle biopsy was suspicion of primary lung cancer in patients who were not surgical candidates. the procedure has high diagnostic feasibility for malignant pulmonary diseases. the most prevalent complication was pneumothorax. however, in most cases, chest tube drainage was unnecessary. no deaths were related to the procedure.

Abstract: in order to study the epidemiology of salmonella enteritidis outbreaks and determine the source of contamination so that a recurrence can be avoided, detailed characterization is necessary. thus, the purpose of this study was to verify whether rep-pcr was able to discriminate among salmonella enteritidis isolates. phage typing, detection of virulence genes and antimicrobial resistance testing were also associated to rep-pcr results. one hundred and two s. enteritidis isolates from broiler carcasses, food, human, pigs, poultry-related samples, and nine isolates from other countries were genotypically typed by rep-pcr, eric-pcr and box-pcr, collectively called rep-pcr. phage typing, detection of virulence genes and antimicrobial resistance testing were also performed. only three fingerprinting profiles were obtained with each rep-pcr method, with the majority of isolates belonging to the same profile. no relationship was observed between genotypic profile and year, place of isolation or source of infection. however, the less frequent rep-pcr profiles showed single antimicrobial resistance patterns. although few strains isolated from swine were analyzed, different antimicrobial resistance patterns were observed. furthermore, phage type 4 was not found in swine isolates. rep-pcr showed a lower discriminatory power as compared with antimicrobial resistance and phage typing, but the combination of genotypic and phenotypic methods was more discriminatory than any method alone, resulting in 48 different types.

Abstract: the objective of this work was to evaluate the effect of stocking density and water salinity levels on lophiosilurus alexandri (pacam?) larvae rearing fed with artemia sp. nauplii. three stocking densities were used: 20, 40 and 60 larvae l-1 (d20, d40 and d60, respectively). for each density, three different levels of salinity were tested: freshwater (s0), 2? (s2) and 4? (s4), in a completely randomized design, in a 3x3 factorial scheme, with three replications. the growth, survival, mortality, cannibalism, production and nonionized ammonia levels were evaluated. the nonionized ammonia levels were higher at d40 and d60. at 10 days of feeding, the weight was affected negatively in d40 and d60 associated to higher water salinity (s4). the higher survival was verified in d20s2 treatment, while smaller values were found in s4, regardless of the density used. small mortality rate and no cannibalism were observed. the juvenile final production was also influenced by the evaluated variables. larvae of l. alexandri can be reared, during the first ten days of exogenous feeding, in freshwater or slightly saline water (2?) with higher juvenile production at density d60.

Revista de Economia Política , 2009, DOI: 10.1590/S0101-31572009000300012
Abstract: this article aims to offer three contributions to the debate on the recent performance of the brazilian economy. first, it presents approximate quarterly figures for the brazilian private investment beginning in 1995. second, it presents estimates of the brazilian "investment function" which are robust to the presence of structural breaks. third, it discusses the sensitivity of private investment to increases in the gross aggregate tax rate. estimates based on national accounting data prior to march 2007 seem to indicate that an increase of 1% of gdp in the tax rate is associated with a reduction of 1% in private investment.

Abstract: O objetivo deste trabalho foi avaliar a tolerancia de larvas de pacam Lophiosilurus alexandri ao teste agudo de salinidade da água em diferentes idades. Os testes foram realizados em larvas recém-eclodidas, com oito e 12 dias pós-eclos o. As larvas foramaclimatadas às condi es experimentais por 24h, sendo estocadas em 18 tanques plásticos de 1 L na densidade de 15 larvas L-1. Após esse período, as larvas foram transferidas para as salinidades: água doce, 2, 4, 6, 8 e 10 g de sal L-1 e observadas durante 96h. Larvas recémeclodidas apresentaram mortalidade total em 6, 8 e 10 g de sal L-1 e 100% de sobrevivência para água doce, 2 e 4 g de sal L-1; porém, com redu o dos valores de peso e comprimento mediante as duas salinidades. Larvas com oito dias pós-eclos o apresentaram CL(I)50-96h de 8,9 g de sal L-1. Para o peso, verificou-se redu o gradativa a partir da salinidade de 2 g de sal L-1, mas sem diferen as para o comprimento das larvas entre os tratamentos. Para as larvas com 12 dias pós-eclos o, n o se registraram diferen as no comprimento e peso e a sobrevivência foi menor a 8 e 10 g de sal L-1. Larvas com oito e 12 dias pós-eclos o tiveram altera es no comportamento natatório em salinidades superiores a 6 g de sal L-1. Larvas de pacam apresentaram maior tolerancia às diferentes salinidades da água com o desenvolvimento ontogenético. The aim of this study was to analyze the salinity tolerance of “pacam ” Lophiosilurus alexandri larvae at different ages. The test was conducted in post-hatching-larvae and larvae with 8 and 12 daysold post-hatching. Larvae were acclimatized to experimental conditions for 24h, kept in 18 plastic tanks with 1 L at a density of 15 larvae L-1. After this period, larvae were subjected tothe salinities: freshwater, 2, 4, 6, 8 and 10 g salt L-1, and observed over a period of 96h. Posthatching larvae exhibited complete mortality in 6, 8 and 10 g salt L-1. Survival was 100% infreshwater, 2 and 4 g salt L-1 – although with the decrease in weight and length values to the salinities of 2 and 4 g salt L-1. The CL(I)50-96h of larvae 8 days old post-hatching was 8.9 g saltL-1. The weight was diminished with the increase in salinity, but no difference was registered in length between the different treatments. Larvae 12 days old post-hatching did not show differences in length and weight. The survival was lower in 8 and 10 g of salt L-1.Larvae 8 and 12 days old post-hatching changed their swimming activity behavior to saline water up to 6 g of salt L-1. “Pacam ” larvae showed higher tolerance to the different salinitieswith larval dev

Via Litterae , 2010,
Abstract: Through the investigations of the Discourse semantics, Martin and White (2005) argue that, in some discursive areas, as the academic, particular conventions of composition has a major influence the evaluative styles used by writers. Thus, this study aims to produce an insightful examination of the linguistic choices that show the evaluation and the identity construction of the reviewer in same reviews of the linguistics academic field. These patterns have more or less rigid, responsible for the standardization of scientific texts. To discuss these choices, we can see how the valuation system, confirms and also cooperates also the establishment of discursive practices and social relations through regular discursive-linguistic mechanisms in a genre whose use is highly required in the academy. These mechanisms show continuously the way it is constructed, diluted or stated the position of the text producer, beyond expose the commitment that this producer/reviewer has with what manifests in the review.

Abstract: O presente artigo faz parte de uma tradi o recente de pesquisas que investigam a avalia o como recurso interpessoal no discurso em contextos dos mais variados. Assim, objetiva uma análise sobre a avalia o e a constru o identitária do resenhista em resenhas acadêmicas da área de Linguística a partir da categoria de engajamento articulada por Martin e White (2005). Nesse sentido, o que se sobreleva e investiga, por meio da identifica o e interpreta o, s o os recursos linguísticos pelos quais o resenhista adota uma postura no sentido de valorizar ou n o posi es que est o sendo referenciadas no texto. O que se observa é o predomínio do endosso e como a avaliatividade nesse gênero pode ser resultado de uma rela o cinética de uma estrutura ainda maior em que est o contextualizadas as diversas ciências sociais em geral.
