Planejamento estratégico em São Paulo: projeto de revitalização central Nova Luz

O presente trabalho analisa criticamente o Projeto de “Requalificação Urbana Nova Luz”, localizado no bairro de Santa Ifigênia em São Paulo, iniciado no ano de 2005 e atualmente em curso. A área abrangida pelo projeto tem aproximadamente 362 mil metros quadrados, é circunscrita pelas ruas Mauá, Av. Cásper Líbero, Av. Ipiranga, Av. São João e Av. Duque de Caxias. Na abordagem inicial colocada pelo projeto emerge o Planejamento Estratégico com um programa cultural e principal motivador de retorno financeiro aos setores imobiliários e de requalificação urbana. Neste cenário, políticas de revitalização são associadas a programas de promoção cultural de museus e monumentos arquitetônicos, recriando uma nova imagem da cidade. Em diversas literaturas a respeito dos programas de revitalização em áreas centrais, é apontado com freqüência - como resultado desses processos - o surgimento do fenômeno de gentrificação, que implica numa substituição dos antigos moradores dessas áreas por outros com maior poder aquisitivo. Essa dinâmica de produção de um espaço revitalizado é geralmente amparada por flexibilizações de Leis e Instrumentos Urbanísticos, bem como financiamentos de agências multilaterais que fixam parâmetros e exigências para liberação dos recursos

Comparação da aptidão física em idosos submetidos a diferentes intervenções de exercício físico

Introduction: The elderly population has increased, and the aging process is responsible for physical and metabolic changes in the body. For the elderly remain independent, with a better quality of life, preventing and treating diseases responsible for this increased of mortality should remain physically active. Objective: To investigate the influence of two types of exercise intervention on physical fitness and physical activity levels in older practitioners of Rio Claro-SP. Method: The study included 18 older adults with mean age 65.8 years (± 2.88) divided into two groups, Program in Physical Exercises Health Unit (PEFUS, n = 9) and Adapted Volleyball (n = 9). Classes of PEFUS were held twice a week lasting 60 min with strength, aerobic endurance, agility, coordination and balance exercises. Classes of Volleyball Adapted were performed 2 times per week lasting 120 minutes, divided into volleyball fundamental exercises and game. For evaluation of physical skills (strength, agility, coordination and flexibility), was performed the AAHPERD test battery. All participants were assessed at the baseline and after 3 months of interventions. The statistical analysis used was the repeated measures ANOVA, through the SPSS version 17.0 and significance level p <0.05. Result: After the interventions there was an increase of leisure time from 362.2 ± 214.9 min / week and 16.7 ± 28.3 min / week to 541.7 ± 137.2 and 44.4 ± 44.8 min / week to Adapted Volleyball and PEFUS, respectively. The variable coordination showed significant improvements after the interventions, decreasing from 12.1 ± 0.7 to 10.8 ± 0.5 sec for Volleyball Adapted and from 14.8 ± 0.9 to 12.1 ± 0, 9 sec for PEFUS (p <0.05). For the variable strength it was observed a group-moment interaction (p <0.05). Conclusion: The interventions showed positive results... (Complete abstract click electronic access below)

As vogais postônicas do século XIII: um olhar sobre a escrita da época

This work aims to obtain a phonological description of unstressed word-final vowels of Medieval Portuguese (MP). The corpus of this research is comprised of Alfonso X’s Cantigas de Santa Maria, composed on the second half of the 13th century. This work maps all the graphemes that represent, in the corpus considered, the unstressed word-final vowels. From the analyses of writing and rhymes in Alfonso X’s Cantigas de Santa Maria, it was possible obtain some important information about the realization of the unstressed wordfinal vowels in MP.

Subepithelial connective tissue graft: a case report

Introduction and objective: Marginal tissue recession represents a common condition in Periodontology. Miller's Classes I and II recessions, in which the etiological factors are well diagnosed and eliminated, show great predictability of total coverage when the technique of subepithelial connective tissue graft is used. This technique success has been mainly attributed to the double blood supply for graft's nutrition, originating from the connective tissue of both the periosteum and flap. Case report and conclusion: The authors reported a clinical case in which a Miller's Class I recession was treated by the surgical technique of subepithelial connective tissue graft, obtaining total coverage, eliminating the aesthetic deficiency and the dentin hypersensitivity complained by patient.

Dimensões das furcas de primeiros pré-molares superiores e sua relação com curetas periodontais

The aim of this in vitro study was to comparatively evaluate the mesio and distal furcation entrance measurements of first maxillary premolar. The measurements were compared with different curette blades. A caliper was used by an examinator to acquire the measurements of root trunk (TR); 1 mm (D1) and 2 mm (D2) both below the furcation entrance. For this study Gracey, Mini Gracey, Padua Lima (PL) and Goldman Fox 4 curettes (Millenium) were selected. Measurements of DT - total distance of the active blade length, DI - width of the active blade, DM - width of the medium part of the active blade were obtained for the curettes. The measurements were obtained in both the coronary face and in the lateral face. The data TR, D1 and D2 presented normal distribution and were statistically analyzed by paired t-test. Statistically significant differences were found in the mesial root trunk region (TR) of both premolars. The mean of the measurements was greater than the distal. Mean and standard deviation were obtained, and both Gracey and Mini Gracey showed mean measurements compatible with the closer furcation entrance (D1 - 1 mm). Goldman Fox 4 showed adaptation only in the mesial face, and Padua Lima showed no access to any of the faces. Thereby it is concluded that the access of the furcation is narrow (D1). The mesial face of the root trunk (TR) showed mean measurement greater than distal face. Gracey and Mini Gracey curettes demonstrated to be compatible for both faces, mesial and distal of the first maxillary premolars studied.

A escola na condição de não lugar

This article portrays the changes that schools and education have been undergoing since the Middle Ages to the contemporary era. Its main focus points at the subjective issues that underlie the school as educational space necessary for the maintenance of society. It ends by showing that the school currently is losing its historical, relational and identity function (essential issues to structure a society) and is becoming a non place (concept of Marc Augé), into an institution without apparent social function, held only as a still a consumable and profitable commodity.

Fatty acid profile and meat quality of young bulls fed ground soybean or ground cottonseed and vitamin E

The objective of this study was to evaluate the fatty acid profile and qualitative characteristics of meat from feedlot young bulls fed ground soybean or ground cottonseed, with or without supplementation of vitamin E. A total of 40 Red Norte young bulls, with an initial average age of 20 months, and an initial average BW of 339 +/- 15 kg, were allotted in a completely randomized design using a 2 x 2 factorial arrangement, with two oilseeds, and daily supplementation or not of 2500 IU of vitamin E. The experimental period was for 84 days, which was preceded by an adaptation period of 28 days. The treatments were ground soybean (SB), ground soybean plus vitamin E (SBE), ground cottonseed (CS) and ground cottonseed plus vitamin E (CSE). The percentage of cottonseed and soybean in the diets (dry matter basis) was 24% and 20%, respectively. Diets were isonitrogenous (13% CP) and presented similar amount of ether extract (6.5%). The animals were slaughtered at average live weight of 464 +/- 15 kg, and samples were taken from the longissimus dorsi muscle for the measurement of fatty acid concentration and the evaluation of lipid oxidation and color of the beef. Before fatty acid extraction, muscle tissue and subcutaneous fat of the longissimus dorsi were separated to analyze fatty acid profile in both tissues. Supplementation of vitamin E did not affect fatty acid concentration, lipid oxidation and color (P > 0.05). Subcutaneous fat from animals fed CS diet had greater C12: 0, C16: 0 and C18: 0 contents (P < 0.03). In addition, CS diets reduced the C18: 1 and C18: 2 cis-9, trans-11 contents in subcutaneous fat (P < 0.05). The muscle from animals fed CS tended to higher C16: 0 and C18: 0 contents (P < 0.11), and decreased C18: 1, C18: 2 cis-9, trans-11 and C18: 3 contents (P < 0.05) compared with SB. The Delta(9)-desaturase index was greater in muscle from animals fed SB (P < 0.01). At 42 days of age, meat from cattle fed SB had a greater lipid oxidation rate (P < 0.05). Meat from animals fed SB diets had less lightness and redness indices than meat from animals fed CS diets after 14 days of age. In conclusion, the addition of ground cottonseed in the finishing diets did increase the saturated fatty acid content of the longissimus dorsi. However, animals fed cottonseed exhibited greater lightness and redness of beef. In this study, the addition of vitamin E did not affect qualitative characteristics of meat.

Efeito da aplicação de biocarvão, cama de frango e formulado NPK no estado nutricional de laranjeira em Terra Mulata

Growing in orange on Terra Mulata has been submitted nutrient limitation requiring correction in agricultural areas. The application of biochar associated with another source of nutrients can be a viable alternative to increase the efficiency of fertilizers and reduce losses in the areas. The objective of this study was to evaluate the effect of biochar, poultry litter and NPK in the nutritional status of orange trees grown in an Oxisol with anthropogenic A horizon (Terra Mulata). The study was conducted in a rural property landfall in Manacapuru (AM) in a randomized block design with eight treatments using biochar, poultry litter and NPK (4-14-8) applied in isolation and associates. To review two samples were taken at different periods of sheets to determine the nutritional status. Fertilizers applied did not increase the efficiency in the availability of contents of N, P, Fe and Zn, being the latter below the range of suitable content. As for the K, compost chicken manure and their combinations increased their availability, and the highest levels of Mg were found in the control treatment.
