Avaliou-se a resistência de genótipos de tomateiro selvagens [Lycopersicon pennellii (LA 716), L. hirsutum var. glabratum (PI 126449, PI 134417), L. hirsutum (PI 127826, PI 127827), L. peruvianum (CGO 6707), L. peruvianum var. dentatum (WYR 2020, LA 111), L. peruvianum var. glandulosum (LA 1113-1, LA 1113-2)] e comerciais [(L. esculentum) Gem Pride, Santa Clara, e híbridos Bruna VFN, Carmem, Fortaleza, Débora Plus VFN] ao ácaro rajado (Tetranychus urticae). O número médio de ovos, fases imaturas (larvas, protoninfas e deutoninfas) e adultos por folíolo foi contado; o índice de preferência para oviposição (IPO) foi calculado. O delineamento experimental foi blocos ao acaso, com 6 repetições. Os genótipos LA 716, PI 126449, PI 134417, PI 127827, PI 127826 e Gem Pride apresentaram não-preferência para oviposição do ácaro rajado, sendo deterrentes quanto à classificação do IPO, enquanto os genótipos LA 111, WYR 2020, LA 1113-2 e LA1113-1 foram os mais preferidos para a oviposição e foram considerados como estimulantes pelo IPO.

Introduction: Open access publishing is becoming increasingly popular within the biomedical sciences. SciELO, the Scientific Electronic Library Online, is a digital library covering a selected collection of Brazilian scientific journals many of which provide open access to full-text articles. This library includes a number of dental journals some of which may include reports of clinical trials in English, Portuguese and/or Spanish. Thus, SciELO could play an important role as a source of evidence for dental healthcare interventions especially if it yields a sizeable number of high quality reports. Objective: The aim of this study was to identify reports of clinical trials by handsearching of dental journals that are accessible through SciELO, and to assess the overall quality of these reports. Material and methods: Electronic versions of six Brazilian dental Journals indexed in SciELO were handsearched at www.scielo.br in September 2008. Reports of clinical trials were identified and classified as controlled clinical trials (CCTs - prospective, experimental studies comparing 2 or more healthcare interventions in human beings) or randomized controlled trials (RCTs - a random allocation method is clearly reported), according to Cochrane eligibility criteria. Criteria to assess methodological quality included: method of randomization, concealment of treatment allocation, blinded outcome assessment, handling of withdrawals and losses and whether an intention-to-treat analysis had been carried out. Results: The search retrieved 33 CCTs and 43 RCTs. A majority of the reports provided no description of either the method of randomization (75.3%) or concealment of the allocation sequence (84.2%). Participants and outcome assessors were reported as blinded in only 31.2% of the reports. Withdrawals and losses were only clearly described in 6.5% of the reports and none mentioned an intention-to-treat analysis or any similar procedure. Conclusions: The results of this study indicate that a substantial number of reports of trials and systematic reviews are available in the dental journals listed in SciELO, and that these could provide valuable evidence for clinical decision making. However, it is clear that the quality of a number of these reports is of some concern and that improvement in the conduct and reporting of these trials could be achieved if authors adhered to internationally accepted guidelines, e. g. the CONSORT statement.

The effect of dietary vitamin (VS) and mineral (MS) mix withdrawal between 42 and 49 d of age on broiler chicken performance was evaluated. The diets were formulated based on corn and soybean meal, and the experiments were conducted in floor pens using wood shavings as litter. Trial I evaluated withdrawal of VS and MS mix at 42, 45, and 49 d. The results of this trial showed that VS and MS mix withdrawal at 42 d of age did not impair feed intake (FI) or weight gain (WG), but feed conversion (FC) was improved (P = 0.043) when both mixes were maintained in the diets until 49 d of age. Trial 2 assessed the withdrawal of VS or MS mix at 42 d of age. FI and WG were not affected by withdrawal, but FC was poorer (P = 0.035) for the broilers fed the diet without VS. The relative liver weight was reduced by VS or MS mix withdrawal (P = 0.014 and P = 0.001, respectively). Carcass, breast, and leg yields were not affected by VS or MS mix withdrawals in either trial. The findings of the study suggested that VS mix withdrawal during the final period of broiler chicken growth was more deleterious than the withdrawal of MS mix, because it affected FC ratio. VS or MS withdrawal during this period did not affect carcass yield.

O acompanhamento do desenvolvimento de bebês implica na consideração de fatores de risco para os mesmos e na utilização de instrumentos que possibilitem a identificação de defasagens, comportamentais, visando à elaboração de intervenções pontuais junto a pais e outros cuidadores. O presente estudo prendendeu descrever variáveis distais e proximais do desenvolvimento de uma amostra de bebês, a partir de suas características peculiares, bem como das dos seus familiares e avaliar o repertório comportamental dos bebês, correlacionando-o com variáveis de risco como prematuridade, baixo peso ao nascer e filhos de mães adolescentes, comparando-o com bebês sem condição de risco identificada. Pretendeu, também, identificar comportamentos típicos nas áres do desenvolvimento avaliadas pelo inventário portage operacionalizado, mês a mês, durante o primeiro ano de vida, utilizando os critérios de estabilização, normalização e aparecimento destes comportamentos entre os meninos e meninas. Participaram do estudo 217 bebês que foram avaliados no decorrer do primeiro ano de vida, sendo que 33% eram prematuros, 28% filhos de mães adolescentes, 11% com baixo peso nascidos a termo, 3% sindrômicos ou filhos de mães portadoras de HIV+ e 25% do Grupo Controle, sem condições de risco identificado no nascimento. Os dados foram coletados a partir da entrevista inicial e da avaliação mensal do inventário. Os dados foram coletados a partir da entrevista inicial e da aplicação mensal do inventário portage operacionalizado (IPO), em um Centro de Psicologia Aplicada de uma universidade pública. Os desempenhos dos bebês no IPO e as condições de risco identificadas foram submetidas ao tratamento por meio do Statistic Package Social for Science (SPSS, versão 12.0). para a identificação de comportamentos típicos utilizaram-se os critérios de Estabilização...

This paper aims to present a study on the development of the real state market in Brazil. The analysis starts from the historical perspective, since the establishment of bases in that market until today's perspective, initial public offering of real state companies. In addition to this analysis, is also intended to discuss the several forms of financing real estate currently available in the Brazilian real estate market. Finally, and perhaps the most important part, analyze the IPO of 15 companies in the industry, held in 2007, notably through comparative graphical analysis, noting the factors that influence stock returns of these companies

This research project aims to determine the main way that the inclusion of topics of history and philosophy of science education activities aimed at high school, influence the process of teaching and learning of chemistry. The subject of research will be a teacher, undergraduate student in chemistry and public school students that the teaching units developed will be applied. The literature presents a large of research indicating the need to include these topics in education and present the results of large withdrawals of original sources of the development of scientific knowledge. Despite of the large number of these works are not very common reports of application of the results of these studies on activities of the classroom, which reinforces the importance of this study
