The objective of this study is to identify and quantify the floristic composition of the weed community in the rice crop waterlogged in the municipality of Arari-MA. The botanical material was obtained in three areas by randomly a hollow rectangle of 0.50 m × 0.30 m by forty five times in each plot. The aerial parts of weeds were harvested, identified, counted and oven dried with forced air ventilation at 333.15 K to 343.15 K. These data were used to determine the phytosociological parameters and the Shannon-Wiener diversity index was also calculated. A total of 6607 plants were collected, being 4115 (62.28%) in the vegetative phase and 2492 (37.72%) in the reproductive phase. The monocotyledonous group obtained the largest number of plants, 2882 in the vegetative phase and 1535 in the reproductive phase. The Cyperaceae family recorded nine species and four genera and the Poaceae, seven and four species in the vegetative and reproductive phases, respectively. The species of higher IVI in the vegetative phase was E. sellowiana in the area A1 with 82.86%, and in the reproductive F. dichotoma with IVI of 90.49% in the area A3. The individuals density and species richness were higher in the vegetative phase of the culture and the monocotyledonous group predominated with the Cyperaceae and Poaceae families, and the weed diversity among the areas was low.

The objective of this work was to verify the responses in agronomic and physiological characters of lettuce seedlings when submitted to different doses of humic acids and the presence or absence of inoculation of the bacterium Azospirillum brasilense. The experiment was carried out at the Protected Cultivation Station and Biological Control Teacher Mário César Lopes, belonging to the Experimental Stations Nucleus of the State University of the West of Paraná. The experimental design was a randomized block design, in a 5 × 2 factorial scheme, with four repetitions, totaling 40 plots. The first factor consisted of five solutions containing humic acid (100%, 75%, 50%, 25% and 0%) and the second factor was the presence or absence of the diazotrophic bacterium Azospirillum brasilense obtained by commercial product. Germination tests were carried out in addition to the determination of agronomic characters such as the number of fully expanded leaves, plant height, stem diameter, main root length, shoot dry mass, root dry mass, total dry mass, and Dickson quality index. The association of diazotrophic bacteria and humic acids did not influence the emergency rate, mean emergence time, mean speed of emergency, emergence speed index, plant height, and root length of lettuce seedlings. The dilutions of humic acids, regardless of inoculation with bacteria diazotrophic favored the development of the number of leaves, stem diameter and Dickson quality index. Inoculation of lettuce seeds with diazotrophic bacteria associated with the addition of humic acids, favored the development of the dry mass of root and total dry matter.

Preliminary Tests of a Kerma-Area Product (KAP) Meter to Be Used as a Monitor Chamber in a Conventional Diagnostic X Ray System

引用

Journal of Modern Physics 2015年第4期6卷 483-489页

作者： Eduardo Correa Regina Medeiros Maria da penha Potiens Vitor Vivolo Nathalia costa Camila Murata Cristina Kikuti Instituto de Pesquisas Energéticas e Nucleares (IPEN-CNEN) Universityof Sao Paulo (USP) Sao Paulo Brazil Federal University of Sao Paulo (UNIFESP) Sao Paulo Brazil

This study presents the results of the preliminary tests performed using a kerma-area product (KAP) meter in order to verify its usefulness as a monitor chamber in a clinical X ray system, which will be used in ionization chambers’ quality control program. The tests performed were repeatability, surface measurement uniformity, linearity with tube current, measurement variation changing the distance and field size, KAP chamber radiation attenuation, and energy dependence. The KAP meter has presented a good repeatability (a maximum variation of 0.4%);its surface has a homogeneous response (a maximum variation of 1.0% among the different irradiated regions);the response is linear with the tube current and the variation of the PKA along the distance is less than 3.43%. On the other hand, the results obtained for chamber attenuation and energy dependence show that some corrections must be applied when the measurements are made. The results have shown a good performance of the KAP meter, confirming that it is possible to use this instrument as a monitor chamber. However, it is important to highlight that some correction factors for energy dependence and chamber radiation attenuation must be considered.

Introduction: Dermatomyositis (DM) and antisynthetase syndrome (ASS) show a high frequency of metabolic syndrome, which can be preceded by endothelial dysfunction and arterial stiffness. To date, only one study has evaluated these vessel parameters in DM, and no study of ASS exists. Therefore, the aim of the study was to assess the structural and functional arterial of arterial vessels in DM and ASS. Methods: This cross-sectional study enrolled 21 adult female patients (14 DM and 7 ASS) who were age-, gender- and ethnicity-matched to 12 healthy individuals. Patients using lipid lowering agents or prednisone at doses ≥ 0.25 mg/kg/day, and patients with uncontrolled systemic arterial hypertension, diabetes mellitus, cardiac insufficiency, and disease activity were excluded. Arterial stiffness was evaluated using carotid-femoral pulse wave velocity (PWV), and endothelial function was evaluated using dependent flow-mediated dilatation (FMD) of the brachial artery. Results: The mean age of patients with DM or ASS were 45.4 ± 8.6 and 44.0 ± 6.1 years, respectively (P = 1.000), and patients were predominantly of white ethnicity. Six DM patients and three ASS patients had systemic arterial hypertension, whereas 9 DM patients and six ASS patients had dyslipidemia. Endothelial baseline diameter, hyperemia diameter and FMD values were similar among the three groups (P > 0.05). Moreover, the median FMD values were also similar between the patients with DM and patients with ASS [8.3% (4.5% - 10.9%) vs. 6.0% (−1.8% - 8.2%);P = 0.585]. The PWV values were comparable among the three groups (P = 0.253). In addition, no difference was observed between patients with DM and patients with ASS (7.4 ± 0.8 m/s vs. 7.4 ± 0.9 m/s;P = 1.000). Conclusions: Despite the high prevalence of dyslipidemia and systemic arterial hypertension, our female patients with stable DM and ASS had FMD and PWV values comparable to those of the control group.

Journal of Biosciences and Medicines 2017年第11期5卷 6-12页

作者： Sebastiao Celio Horta Coelho Filho Thiago Sande Miguel Nayrton Kalys Cruz dos Anjos Mateus de Oliveira Reis bruna Sande Miguel Vinicius Sande Miguel Aline Gabriela Santos costa Lilian costa Brito Bruno Fonseca dos Santos Veronica Clemente Villar Martini Daniel Almeida da costa The Medical School at the Center of Higher Education of Valenca ValencaBrazil Unigranrio Medical School Rio de JaneiroBrazil

Introduction: The involvement of undergraduate student at the beginning of their training in activities based on Primary Health Care (PHC), provides preventive and health promoting actions, and ensures the evaluation of the vulnerability of communities and people. Objectives: To analyze the opinion of students and teachers of two medicine higher education institutions on the relevance of Primary Health Care in this course. METHODS: Students and teachers should be effectively enrolled in order for the study to be conducted, being chosen in a random manner and without interferences on the part of the researchers so that the work was as reliable as possible. A cross-sectional study was conducted with interviews structured in questionnaires about what they thought about PHC. To some students and teachers of the medical course of Valen?a and Grande Rio University (UNIGRANRIO). Before receiving the questionnaire, all interviewed signed a Free and Informed Consent Term, which included the objectives and methodology of the work. Results: 310 students and 51 teachers participated in the study, where 91.43% of the students and 100% of the teachers affirmed that primary care plays a fundamental role in medical education. 94.86% of students and 97.91% of teachers, claimed that the discipline allows a greater contact between undergraduates and community. When questioned about the encouragement that teachers give to students to pursue a career in PHC, 57.87% of the students and 70.83% of the professors said they lacked in such a stimulus. Conclusion: PHC is still very neglected by governmental policies, educational institutions and by the own teachers, that often, turn they attention only to tertiary medicine and, as a consequence, a discouragement of this area occur. Therefore, a higher PHC value is necessary, allowing a more humane look at the patient, valuing their feelings, anguishes and their pathological framework.
