Literatura e emigração : olhares cruzados (Nita Clímaco, Assis Esperança, Olga Gonçalves e Amândio Sousa Dantas) : estudo comparatista para utilização desta temática no ensino secundário

O principal objetivo deste trabalho é apresentar uma análise da temática da emigração nas obras de quatro autores que se mantêm afastados dos programas curriculares: António Assis Esperança, com Fronteiras, Nita Clímaco, com A salto, Olga Gonçalves, com Este verão o emigrante là-bas e Amândio Sousa Dantas com Poesia da emigração. Numa primeira parte são definidas as noções de Literatura, História, Ficção e Contexto histórico e explicitadas as relações existentes entre conceitos. A segunda parte aborda a Imagologia enquanto teoria satélite da disciplina de Literatura Comparada. Neste âmbito, apresenta brevemente as várias tendências comparatistas e detém-se nas noções de ficcionalidade, teoria da receção e intertextualidade. Define e estabelece distinções entre Tema e Motivo, e por fim propõe uma abordagem comparativa dos temas: “Representações do Feminino” e “Imagem do Estrangeiro”. Na terceira parte, recorrendo à metodologia comparatista foi realizada uma análise transversal dos motivos: “Retrato de um país – Portugal nas décadas de 1960 - 1980”, “A Emigração”, “ A Viagem – o Salto”, “O choque cultural e linguístico” e “ A Saudade”. Todas as abordagens dos temas e dos motivos iniciam com uma apresentação teórica, resultado das leituras feitas ao longo da investigação. Por fim, o último capítulo expõe algumas propostas para o tratamento das obras e da temática nas aulas de Português no ensino secundário, para um trabalho interdisciplinar com História e um Projeto de Turma envolvendo as restantes disciplinas.

Serie de Documentos. Facultad de Jurisprudencia N° 74. Perspectivas de la responsabilidad estatal por el daño ambiental en Colombia: dificultades para su exigibilidad y efectividad desde la jurisprudencia del Consejo de Estado

El presente artículo aborda el tema de la responsabilidad del Estado por el daño ambiental y las limitaciones del sistema tradicional de responsabilidad jurídica adoptado por el Consejo de Estado para su exigibilidad y reparación efectiva. En especial, afronta las dificultades que se presentan para establecer la prueba del daño y el nexo de causalidad para su imputación al Estado, así como la conveniencia de mitigar esa exigencia en consideración a las connotaciones propias y especiales de esta clase de menoscabos. Propone igualmente que en todos los casos en que se verifique la existencia de un daño ambiental se adopten en la jurisprudencia del Consejo de Estado las medidas tendientes a rehabilitar el medio ambiente afectado, cuando ello fuere posible, o proceder a su compensación o indemnización plena.

Effects Of Programmed Physical Activity On Body Composition In Post-pubertal Schoolchildren.

To assess body composition modifications in post-pubertal schoolchildren after practice of a physical activity program during one school year. The sample consisted of 386 students aged between 15 and 17 years and divided into two groups: the study group (SG) comprised 195 students and the control group (CG), 191. The SG was submitted to a physical activity program and the CG attended conventional physical education classes. Body composition was assessed using body mass index (BMI), percentage of body fat (%BF), fat mass (FM), and lean mass (LM). A positive effect of the physical activity program on body composition in the SG (p<0.001) was observed, as well as on the interaction time x group in all the variables analyzed in both genders. A reduction in %BF (mean of differences = -5.58%) and waist circumference (-2.33cm), as well as an increase in LM (+2.05kg) were observed in the SG for both genders, whereas the opposite was observed in the CG. The practice of programmed physical activity promotes significant reduction of body fat in post-pubertal schoolchildren.

Biogenic Silver Nanoparticles Associated With Silver Chloride Nanoparticles (ag@agcl) Produced By Laccase From Trametes Versicolor.

In the present study, semi-purified laccase from Trametes versicolor was applied for the synthesis of silver nanoparticles, and the properties of the produced nanoparticles were characterized. All of the analyses of the spectra indicated silver nanoparticle formation. A complete characterization of the silver nanoparticles showed that a complex of silver nanoparticles and silver ions was produced, with the majority of the particles having a Ag(2+) chemical structure. A hypothetical mechanistic scheme was proposed, suggesting that the main pathway that was used was the interaction of silver ions with the T1 site of laccase, producing silver nanoparticles with the concomitant inactivation of laccase activity and posterior complexing with silver ions.

Dental caries and related factors in Brazilian children from fluoridated and non-fluoridated areas

PURPOSE: To compare the caries prevalence, saliva buffering capacity (SBC), oral hygiene (OH), dietary habits, family income (FI) and frequency of visits to a dental office (Do) between Brazilian children living in areas with and without fluoridated public water supply. METHODS: Forty-six 5-7-year-old preschoolers were selected in Itatiba, SP, Brazil; 19 were from a fluoridated area, and 27 were from a non-fluoridated area. The caries index was determined according to the World Health Organization criteria, and the SBC was assessed by titration with hydrochloric acid. The FI, frequency of OH and visits to Do were estimated by questionnaire. The dietary habits were assessed with a diet chart. The differences between the groups were analyzed with Mann-Whitney-U tests (α=0.05). RESULTS: Children from the non-fluoridated area showed significantly higher dmft/DMFT than those from the fluoridated area, but they showed significantly lower SBC, OH frequency and FI. No significant differences were observed between the areas for dietary habits and visits to Do. CONCLUSION: Children from fluoridated areas showed higher salivary buffering capacity, family income and oral hygiene frequency as well as lower caries prevalence, supporting the beneficial effect of fluoride in the tap water for caries prevention.

Analysis of the stimulated whole saliva in overweight and obese school children

OBJECTIVE: To determine if some stimulated whole saliva parameters are influenced by an increase of Body Mass Index. METHODS: Controlled cross-sectional study involving 90 school children of both genders between 7 and 10 years of age, from Bragança Paulista - SP. Three groups were formed: overweight, obese and control. Body Mass Index and diet intake by the Food Register method were evaluated. The salivary pH, flow rate, buffer capacity, protein, phosphate, calcium, fluoride, total and free sialic acid, and peroxidase activity were determined. RESULTS: The overweight and obese groups showed greater energy and lipid intake (P< 0.001) than the control group. There was no difference in the saliva flow rate between groups, however only the control group showed a mean value considered normal. In the overweight and obese groups a decrease in both the concentration of phosphate (P< 0.001) and peroxidase activity (P<0.001) was observed. In the obese group an increase in the concentrations of free sialic acid (P= 0.004) and protein (P= 0.003) occurred. CONCLUSION: Overweight and obese children show alterations in the concentrations of phosphate, free sialic acid and proteins, and in the peroxidase activity that are favorable conditions for dental caries.

Antibiosis and dark-pigments secretion by the phytopathogenic and environmental fungal species after interaction in vitro with a Bacillus subtilis isolate

In this work, different reactions in vitro between an environmental bacterial isolate and fungal species were related. The Gram-positive bacteria had terminal and subterminal endospores, presented metabolic characteristics of mesophilic and acidophilic growth, halotolerance, positive to nitrate reduction and enzyme production, as caseinase and catalase. The analysis of partial sequences containing 400 to 700 bases of the 16S ribosomal RNA gene showed identity with the genus Bacillus. However, its identity as B. subtilis was confirmed after analyses of the rpoB, gyrA, and 16S rRNA near-full-length sequences. Strong inhibitory activity of environmental microorganisms, such as Penicillium sp, Aspergillus flavus, A. niger, and phytopathogens, such as Colletotrichum sp, Alternaria alternata, Fusarium solani and F. oxysporum f.sp vasinfectum, was shown on co-cultures with B. subtilis strain, particularly on Sabouraud dextrose agar (SDA) and DNase media. Red and red-ochre color pigments, probably phaeomelanins, were secreted by A. alternata and A. niger respectively after seven days of co-culture.
