PREPARATION AND CHARACTERIZATION OF A COMPOSITE OBTAINED THROUGH Ti (IV) AND PHOSPHORIC ACID

This paper describes the preparation and complementary characterization of a composite formed from the activation of titanium isopropoxide by phosphoric acid and deionized water (TiP). Techniques such as, X-ray diffraction (XRD), Raman, electronic (UV-vis) and Scanning electron microscopies (SEM) were used for characterization of this new composite formed. In the X-ray diffractogram of TIP was observed four intense peaks. A strong absorption was observed in the region 362-445 nm. The scanning electron microscopy of TiP, shows that the prepared material consists mostly of a cluster of spherical particles with diameters ranging from 2.35 to 2.60 mu m.

Indícios de subjetividade na fala de uma criança psicótica: um olhar para as hesitações

This study, performed under a linguistic-discoursive prism, aimed to: (1) describe the moments in which occurred hesitations in the utterances of a psychotic child diagnosed with Language Disorder; and (2) determine the extent to which these moments (also) can indicate aspects of a subjectivity trying to emerge in this child. Data were extracted from a speech therapy session with a ten year old female child. Concerning the fi rst goal, from a total of 362 utterances produced by the child, only 74 (20%) had hesitation traces, while 288 (80%) did not. Concerning the second goal, the utterances with hesitation traces occurred in situations of: topic development, especially in the form of complementarity; introduction of new topic; return to the previous topic; refuses to the topic; enunciative incompleteness. The high percentage of utterances without hesitation traces (80%) is explained because they are highly predictable from the context, mostly in situations of ritualized adjacent pairs, oftentimes in situations of immediate specularity. The reduced percentage of utterances with hesitation traces are explained precisely by the fact that, unlike those without traces, in these ones, signs of a subjectivity that tries to emerge and show itself in the discourse production are detected. With the development of this study, we tried to emphasize the view at the hesitations as marks of subjectivity – in other words, evidences of confl icting relationships between the subject and the others that constitute the utter. The concern was also about bringing to the fi eld of Speech Pathology discoursive linguistic refl ections based on data extracted from symptomatic contexts of language.

A new tuning fork with different vibration frequencies as an aid to bronchopulmonary hygiene physiotherapy

Background: The main function of the mucociliary system is the removal of particles or substances that are potentially harmful to the respiratory tract. The tuning fork therapeutic for the purpose of bronchial hygiene has still not been described in the literature. The optimal vibration frequency to mobilize secretions is widely debated and varies between 3 and 25 Hz. It is expected that a tuning fork is able to generate vibrations in the thorax, facilitating bronchial hygiene. The aim of the present study is to develop tuning forks with different frequencies, for use in bronchopulmonary hygiene therapy. Methods: The first tuning fork was made with a fixed frequency of 25 Hz and it was recorded in the Brazilian institution of patent registration. This device generated a frequency of 25 Hz and had a weight of 521 g, with dimensions of 600 mm in total length. The device is characterized by a bottom end containing a transducer with a diameter of 62 mm and a thickness of 5/16 mm (8''), a rod removable 148 mm, fork length of 362 mm and an extension at the upper end of sinuous shape bilaterally.The tuning forks must be applied at an angle of 90° directly on the chest wall of the patient after pulmonary auscultation for location of secretions. The tuning fork is activated by squeezing the tips of the extensions together and releasing them in a sudden movement. Results: This study shows the result of the development of others three tuning forks of different dimensions to generate different frequencies. Each equipment reaches a fixed frequency preset of 12, 15 and 20 Hz measured by digital oscilloscope. Conclusions: The tuning fork models developed in this study generated different frequencies proposed by the scientific literature as effective in the mobilization of pulmonary secretions.

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)
