Abstract: this work aimed to estimate genetic parameters related to the fruits production in a chilli pepper diallel (capsicum baccatum var. pendulum). five chilli pepper genitors were evaluated (uenf 1616, uenf 1624, uenf 1629, uenf 1639 and uenf 1732) and its respective hybrids f1, from a complete diallel without reciprocals. the experiment was carried out in a greenhouse covered with plastic film located in area from the consortium uenf/pesagro-rio, campos dos goytacazes, rj, from july/2009 to december/2009, in a randomized block design with three repetitions and nine plants by plot. the following agronomic traits were evaluated: canopy diameter (cd); plant height (ph); days for fruiting (df); number of fruits by plant (nfp); fruit average-weight (faw); fruit dry mass (fdm); dry matter (dm); fruit length (fl); fruit diameter (fd); fruit wall thickness (pt); total soluble solids (tss); and yield per plant (prod). only the faw, fdm and prod had absence of significance concerning the three tests of sufficiency for the additive dominant model, indicating that there is homogeneity among the variances and co-variances and, consequently, lack of epistasis in the control of character. for the faw and fdm traits, the additive genetic effects were the most important ones. nevertheless, in the prod the dominance effect was the most important. it was verified a partial dominance for faw and fdm, and an over-dominance for prod. the genitors uenf 1616 and uenf 1629 were the ones which had larger concentrations of favorable alleles for the three characteristics under study.

Abstract: Este artigo apresenta dados coletados em nossa pesquisa de doutorado. Temos por objetivo refletir sobre o quadro referente à forma o dos professores que ministram a disciplina de física no Ensino Médio. Analisamos dados do Mec/Inep sobre a forma o dos professores que ministram a disciplina de física no Brasil e do Censo Escolar da Educa o Básica. Constatamos que os professores que ministram a disciplina de física no Ensino Médio s o, na maioria, licenciados em matemática; e, levando em considera o autores que discutem a forma o de professores, analisamos as ementas das disciplinas de física, bem como sua carga horária e os conteúdos ministrados em 27 cursos de licenciatura em matemática de institui es de Ensino Superior. Concluímos que os dados s o preocupantes, pois, além de serem poucos os professores com forma o específica na área de física, os demais docentes que ministram esta disciplina n o têm forma o adequada para atuar nessa área do conhecimento. This article presents collected data from our doctoral research; we aim to reflect on the scenario for the training of teachers who teach the discipline of Physics in high school. We analyzed data from Mec/Inep on the training of teachers who teach the discipline of Physics in Brazil and in the Basic Education School Census. We noted that teachers who teach the discipline of Physics in high school have mostly majored in Math and, taking this into consideration the authors discuss the teachers' training. We noted the menus of the disciplines of Physics, as well as its workload and the subjects taught in 27 undergraduate programs in Mathematics from higher education institutions. We concluded that the data are worrying because, besides there being only a few teachers with specific training in Physics, the other teachers who teach this subject do not have adequate training to teach in this area of knowledge.

Abstract: the factors that make difficult the normalization of tsh in hypothyroidism need special attention because some patients on thyroxine replacement do not maintain a normal tsh. we report a 50 year-old woman with autoimmune hypothyroidism of difficult compensation, associated with anemia, hypocalcemia with a previous episode of tetany, hypomagnesemia, psychologic alterations and important weight loss. after compensation of the hypothyroidism with doses of l-thyroxine as high as 325μg/day, the hypothesis of a malabsorptive syndrome was raised. celiac disease was confirmed by elevated serum antigliadin antibody. a gluten-free diet was instituted which improved the symptoms associated with malabsorption and reduced the l-thyroxine requirement to 125μg/day. because several studies have shown an association of both diseases, a routine screening for celiac disease has been widely proposed in patients with autoimmune thyroid disease.

Abstract: Despite the well-documented health benefi ts of physical activity, many college students are not physically active on a regular basis. However, the university setting provides students with skills and knowledge about healthy lifestyles, especially in physical education and sport classes. The purpose of this study was (a) to provide descriptive data about stages of behavior change and habitual physical activity levels in representative sample of physical education and sports college students; and (b)to investigate the congruence between stage of behavior change and self-reported habitual physical activity levels in the college sample. A sample of 590 college students (270 girls and 320 boys) aged 18-35 years old were included in the study. Stages of behavior change for physical activity adoption was assessed with an algorithm based on transtheoretical model. The short version of the International Physical Activity Questionnaire was used to assess the habitual physical activity. The results showed that grade level and period may play a signifi cant impact in habitual physical activity among college students of both gender. Stages of behavior change and habitual physical activity level were signifi cantly related to some socio-demographic variables, such as gender, age, economic status, habitation, time of work, overweight and tobacco use. The magnitude of sensitivity, specifi city and efficiency showed that the congruence between stage of behavior change and self-reported habitual physical activity levels is fragile, especially in girls. In conclusion, the fi ndings of study represent a fi rst step in better understanding the socio-demographic factors associated with the adoption of a regularly active lifestyle among physical education and sport college students. The results reveals that the stages of behavior change algorithm used in the study not is appropriate for to identify the levels of habitual physical activity and need to be further investigated in the college population. RESUMO A despeito dos benefícios da atividade física para a saúde serem bem documentados, muitos estudantes universitários n o s o regularmente ativos. No entanto, o ambiente universitário proporciona aos acadêmicos habilidades e conhecimentos quanto à ado o de um estilo de vida saudável, especialmente àqueles dos cursos de educa o física e de esporte. Os objetivos do estudo foram (a) apresentar informa es descritivas quanto aos estágios de mudan a de comportamento e aos níveis relatados de prática habitual de atividade física em amostra representativa de acadêmicos dos cursos

Abstract:

One of the methods to determine the tolerance of plants to water stress is the observation of germination of seeds under stress induced in laboratory conditions. Thus, the aim was to evaluate the response of four common bean cultivars to water deficit simulated under laboratory conditions. Two common landrace genotypes acquired from farmers (FORT 07 and FORT 08) and two commercial cultivars, IAPAR 81 and Serrano were evaluated. The different levels of water deficit were induced with mannitol solution. The experimental design was completely randomized and a factorial scheme 5 × 4 (osmotic potential x genotypes), with four replications. The characteristics: primary root protrusion, seed vigor, normal and abnormal seedling, seedling and root length, fresh and dry weight of seedling and root were evaluated. By reducing the osmotic potential seedling vigor bean was more affected than the primary root protrusion. Regardless of cultivar, there was a significant and progressive reduction in the normal seedlings percentage from potential -0.3 MPa. The IAPAR 81 and FORT 07 cultivars showed higher tolerance to water deficit compared to other cultivars.

International Journal of High Dilution Research , 2011,
Abstract: Introduction: Culex is an insect of the family Culicidae. It occurs in tropical and subtropical regions. It is known as the domestic mosquito. Their larvae develop in stagnant and dirty water, with plenty of organic matter. Some species of the insect such as Culex quinquefasciatus transmit the worms (helminths) called Wuchereria bancrofti filariasis or Elephantiasis. Aims: Thus, the objective of this work was to evaluate the effect of isotherapic of Culex on the biological cycle of this insect. Material and Method: The experiment was conducted at the Laboratory of Plant Physiology and Homeopathy at the State University of Maringa in the period from March 26 to December 31, 2007. Fifteen larvae of Culex sp. the same stage of development (Stage I) were used in the experiment with Isopathy of Culex sp. Was added 200 microliters of the dilutions of isotherapic 3, 6, 9, 12, 18, 24 and 30cH in each flask containing 30 mL of water and 15 larvae of Culex sp. The control consisted of 30 mL of water and 200 mL of 5% alcohol. The flasks were covered by tissue "toule"-type to prevent the dispersal of adult insects. The dilutions were produced according to the Brazilian Homeopathic Pharmacopoeia (1987) [1]. Were determined: average number of larvae, pupae and mosquitoes during the cycle of the insect. Results and Discussion: The presence of Culex isotherapic in the growth solution presented complex responses. Some dilution caused positive responses (3, 6, 9, 12 and 18cH) in the average number of larvae (Figure 1). Dilution 18cH apparently caused a protective effect, and somehow minimized the negative influence of the environment, or protect the larvae from unfavorable abiotic conditions. Dilutions 6, 18 and 24 cH, instead, caused adverse effect on larval and pupa survival, but positive when we consider the objective of this work. There is an interesting phenomenon when evaluating the biological responses in living according to the dilution used. The alternation of rises and falls in the physiological variables as a function of dilution were observed by several authors [2-5]. It behavior is not explained by science, but it is believed to be related to the rhythmic nature movement [6,7] and also with the law of similarity occurring between dilution and the organism that receives it. Thus, the physiological function of the dilutions in the same drug are often cyclical and not linear. Conclusion: The results of this experiment suggest that some dilution may be used in studies to control the mosquito Culex sp.
