Abstract: The abscisic acid (ABA) is related to the formation of certain polyphenols, such as anthocyanin, improving the nutritional and commercial quality of the red grapes. In this study, we verified whether the exogenous application of?S-ABA favors the accumulation of anthocyanin, the total phenolic compounds and the antioxidant activity of the?‘Rubi’?grape. The experiment was performed during the cycle 2014/2015 with the?‘Rubi’?vine (Vitis viniferaL.) grafted in the rootstock 420-A. The experimental design was composed of randomized blocks, with four treatments and six blocks, in a total of 24 experimental parcels, constituted of one plant each. We used the?S-ABA isomer in different concentrations and times of application, 400 mg·L-1S-ABA in the beginning of the ripening (BR); 400 mg·L-1?at BR + 200 mg·L-1?at 25 days after first application (DAFA); 400 mg·L-1at BR + 400 mg·L-1at 25 DAFA; besides the control (0 mg·L-1). After 40 days of the first application, the samples were harvested and

Abstract: The Conservation Units (CU) were created to protect natural environments from growing degradation and to impede the expansion of urbanization and agricultural crops. The Serra da Canastra National Park, established to protect the headwaters of the S?o Francisco River and other places of scenic and ecological interest, is extensively visited due to its many tourist attractions, such as waterfalls, fauna and flora. An analysis of the park’s geography is needed to assess the risk involved in and its suitability for public use due to its territorial extension and environmental complexities. Thus, this study aimed to investigate the background of issues of interest to CU management. Additionally, we used high-resolution RapidEye imagery, altimetry and database of park infrastructure to build geospatial database and estimate classes of suitability for and risk in public use through GIS tools. The resulting cartographic data can support the planning of policies concerning the landscape and park’s territorial management.

Psico , 2011,
Abstract: Os motivos para uso de álcool s o variáveis importantes que ajudam a compreender o consumo de bebidas alcoólicas. Motivos para usar álcool podem ser representados através de uma estrutura de quatro dimens es inter-relacionadas: social, realce, coping e conformidade. O objetivo desta revis o de literatura é apresentar o conceito de motivos para uso de álcool, distinguindo-o de expectativas sobre o uso e enfatizando seu duplo papel como preditores e mediadores em estudos sobre o uso de álcool. Modelos fatoriais empíricos representativos do construto e algumas dificuldades na avalia o s o também debatidas. Ao final, ressalta-se a utilidade potencial da avalia o de motivos para uso de álcool em situa es de interven o clínica com alcoolistas e a necessidade de constru o e adapta o de instrumentos de avalia o no país.
Calculus in physics classes at UFRGS: an exploratory study
Maria Cecilia Pereira Santarosa,Marco Antonio Moreira
Investiga??es em Ensino de Ciências , 2011,
Abstract: This study is part f a larger one whose general objective is to investigate and to develop a new strategy for teaching Differential and Integral Calculus I, specifically for physics majors, through a possible integration with the teaching of General and Experimental Physics I. With the specific objective of identifying physics problem-situations that may help in making sense of the mathematical concepts used in Calculus I, and languages and notations that might be used in the teaching of Calculus to favor physics learning, it was investigates, through an ethnographic study, the may mathematics is transposed to classes of General and Experimental Physics I, in classes of physics courses at the Federal University of Rio Grande do Sul (UFRGS). Some findings of this study confirmed those reported in the literature regarding the teaching and learning process in introductory college physics courses. These findings will subsidize the preparation of potentially meaningful instructional materials that will be used in a second stage of the research designed to investigate the learning of declarative and procedural knowledge in basic college physics under an approach that integrates problem-situation in physics and calculus mathematical concepts.

Rationale: In a previously published trial on spinal acute non-traumatic pain, peripheral neuro- regenerative combination of UTP, CMP and hydroxocobalamin presented unexpected analgesicproperties. Objective: To corroborate analgesiceffects of UTP, CMP and hydroxocobalamin combination in a self-paired evolutionary model. Methods: Mean VAS scores from pretreatment, V2 (5th treatment day) and V3 (10th treatment day) were plotted and statistically analyzed (ANOVA) for differences. PFQ scores from pretreatment, V2, and V3 were analyzed using the chisquare test. Results: The difference between V3 and pretreatment mean VAS scores was statistically significant (p < 0.0001). The improvement in PFQ scores throughout the study was found to be statistically significant (p < 0.0001). Conclusion: The combination of UTP, CMP and hydroxocobalamin seems to have analgesic properties in mediumterm use. The complex peripheral neu-roregenerative pharmacodynamics of this combination provides a plausible basis for this finding. Further randomized studies are needed to explore this combination for the indication of neuropathic pain due to spinal structure involvement.

Abstract: Objective: To analyze the Patient Functionality Questionnaire (PFQ) scores of the patients treated with either Diclofenac + B vitamins (Group DB) or Diclofenac monotherapy (Group D) in order to better understand the impact of the combination of diclofenac with vitamins B1, B6, and B12 on quality of life. Research Design/Methods: We performed a post-hoc analysis of tabulated data generated during the DOLOR study (Diclofenac plus B vitamins versus diclofenac monotherapy in lumbago: the DOLOR study), using the software GraphPad Prism 5 for Windows, v5.04. The absolute number or percentage of “True”/“False” respondents for each questionnaire item at each study visit, together with the absolute number and percentage of subjects with no change, improvement, or worsening of each PFQ item at each study visit, within and between treatment groups were arranged on contingency tables and analyzed with the Chi-squared or Fisher’s Exact test. Results: At pretreatment there were no statistically significant differences between treatment groups (p > 0.05 for all items). At Visit 2 in both treatment groups, there were statistically significant improvements in individual question responses in each of the 12 items of the questionnaire (p < 0.05 for all items). At Visit 2, comparing the distribution of patients in each treatment group with “improvement”, “no change”, or “worsening”, there was a statistically significant superiority among subjects of group DB in response to items 1, 6, 8, and 10. At Visit 3, both groups had statistically significant (p < 0.001) improvements in each individual item of the PFQ in relation to pretreatment values. The distribution of subjects in each treatment group presenting with “improvement”, “no change”, or “worsening” at Visit 3 varied significantly in favor of group DB in the responses to item 4. At Visit 4, the subjects remaining in treatment in both groups showed statistically significant improvement in PFQ responses in relation to pretreatment values (p < 0.05). The distribution of subjects in each treatment group presenting with “improvement” or “no change” at Visit 4 varied significantly in favor of group D in the responses to items 5, 8, and 12. Conclusion: Improvement in overall PFQ scores was observed in both treatment groups, though the specific items of the questionnaire of the subjects in group DB at Visit 2 showed greater improvement in areas related to sleep quality, mobility, ability to wash and dry, ability to walk distances, and posture comfort. These results serve to corroborate the

Abstract: the objective of this work was to study dm, ndf, cp and ipnd ruminal kinectics of irrigated tanzaniagrass (panicum maximum jacq.). simulated grazed samples were collected on three periods of the year (spring, summer and fall), under three post grazed stubbles intensities (low, medium and high). three rumen cannulated animals were assigned to a 3 x 3 latin square design to determine the in situ degradability until 96 hours of incubation. ndf, cp and ipnd were determined by nirs in the residue remaining in the bags. forage quality was the highest in the summer. the low post grazed stubble treatment showed the highest increase in degradability of all fractions from spring (74.96%) to summer (81.41%). the soluble protein fraction showed values up to 40% of the rdp, which ranged from 62 to 76% cp. ndf c fraction was underestimated by cncps. data of this research suggest that the %lignin/%ndf should be multiplied by a factor from 2.91 to 3.35. cncps overestimated the ipnd c fraction (12.11 to 17.08%), as compared to the wet lab analysis value, as regarded to be the n-adf fraction (6.48 to 10.7%). cp and ipnd degradability decreased, as the cp and ipnd contents increased.
