Professores de educação física e suas consequências na unidade escolar

This article aims to show the interdependence between teaching practice and the construction of body hexis of Physical Education teachers and its consequences at schools. It can be observed by the social workers that teach it in a elementary school in the city of Araraquara- -SP. It was established, as basic assumption of this issue, that the social construction of body hexis of Physical Education teachers is a process in constant evolution, because it is the result of the life story with interventions from the social context in which the learner lives. The hexis is the dimension that allows the internalization of the consequences of social practices, and also its body exteriorization, through the way of speaking, gesturing, looking, walking, head posture, faces, ways of sitting, to handle instruments, more and more associated with the voice sound of social workers. Children are particularly attentive, in all societies, to these gestures and postures in which they express themselves in their eyes, anything that features an adult. Finally, it understands the importance of the body hexis in the learning process specifically in school physical education. This practice will incite important behavioral changes in their residence within the school and possibly in a higher education.

Implantes curtos em região posterior da mandíbula

The rehabilitation of edentulous areas with osseointegrated dental implants is a well-documented, predictable procedure in the literature, with high success rates. However, the lack of bone at the recipient bed or proximity to anatomic structures limits the rehabilitation procedure especially at the posterior mandible. Thus, short implants are an alternative treatment for such cases of severe bone resorption. The purpose of this study was to review the success rate of short implants, especially those based in the posterior mandible and to show a clinical case. A literature review was made on electronic databases PubMed and Bireme with articles published between the years 2005 to 2012, using the keywords "short dental implants". It was concluded that the success rates of short implants are similar to those presented by conventional implants but still related to their geometry and surface treatment. Also, short implants can be considered as a viable alternative for the rehabilitation of severely resorbed jaws. However, many authors consider that more research is necessary when a short implant is compared to a long dental implant.

Early correction of malocclusion using planas direct tracks

The correction of functional posterior crossbite through Planas Direct Tracks has many characteristics that can become advantages. The aim of this study was to present a clinical case showing how to use this procedure for early correction with resources available through public health services. The patient, a 4-year-old girl, arrived to receive treatment due to a functional unilateral crossbite. When the mandible was moved to the centric position, it was observed that the teeth had occlusal trauma. An occlusal adjustment was performed. The adjustment was not sufficient to promote functional equilibrium; thus, Planas Direct Tracks were made, resulting in functional equilibrium and correction of the malocclusion. As shown in the case report, the Planas Direct Tracks were effective for the correction of the posterior crossbite. If malocclusion is considered a public health problem, implementation of low-cost and easy-to-execute techniques is needed.

Reconstruction of maxillary ridge atrophy caused by dentoalveolar trauma, using autogenous block bone graft harvested from chin: a case report

Background Dentoalveolar trauma, especially when involving front teeth, negatively affect the patient’s life; in particular, tooth avulsion is a complex injury that affects multiple tissues, and no treatment option offers stable long-term outcomes. The aim of this study was to report a case of reconstruction of atrophic anterior alveolar ridge after tooth loss, performed with autograft harvested from the chin, and subsequent prosthetic rehabilitation with the use of an osseointegrated implant. Case report A 23-years-old Caucasian girl, presented an atrophic alveolar bone in the area of tooth 11, as a result of tooth resorption 10 years after a tooth reimplantation procedure. Reconstruction was performed with autogenous bone harvested from the chin. After 6-months healing period to allow autograft incorporation, a dental implant was inserted. After further 6- months, a screw-retained implant supported metal-ceramic prosthesis was fabricated. Results The prosthetic rehabilitation was successful, and after a follow-up period of 5 years, the achieved result was stable.Conclusion It can be concluded that the autogenous bone graft harvested from the chin, is a safe and effective option for alveolar ridge defects reconstruction, allowing a subsequent placement of a dental implant supporting a prosthetic restoration.

New analytical procedure based on a cellulose bag and ionic exchanger with p-aminobenzoic acid groups for differentiation of labile and inert metal species in aquatic systems

A new procedure was developed for the in situ characterization of the lability of metal species in aquatic systems by using a system equipped with a diffusion membrane and cellulose organomodified with p-aminobenzoic acid groups (DM-Cell-PAB). To this end, the DM-Cell-PAB system was prepared by adding cellulose organomodified with p-aminobenzoic acid groups (Cell-PAB) to pre-purified cellulose bags. After the DM-Cell-PAB system was sealed, it was examined in the laboratory to evaluate the influence of complexation time, mass of exchanger, pH, metal ions (Cu, Cd, Fe, Mn, and Ni), and concentration of organic matter on the relative lability of metal species. It was found that the pH and kinetics strongly influence the process of metal complexation by the DM-Cell-PAB system. At all pH levels, Cd, Mn, and Ni showed lower complexation with Cell-PAB resin than Cu and Fe metals. Note that relative lability of metals complexed to aquatic humic substances (AHS) in the presence of Cell-PAB resin showed the following order: Cu congruent to Fe >> Ni > Mn=Cd. The results presented here also indicate that increasing the AHS concentration decreases the lability of metal species by shifting the equilibrium to AHS-metal complexes. Our results indicate that the system under study offers an interesting alternative that can be applied to in situ experiments for differentiation of labile and inert metal species in aquatic systems.

A COMBINATION OF METHOTRIMEPRAZINE, MIDAZOLAM AND GUAIPHENESIN, WITH AND WITHOUT KETAMINE, IN AN ANESTHETIC PROCEDURE FOR HORSES

A combination of 0.5 mg/kg of methotrimeprazine, 0.1 mg/kg of midazolam and 100 mg/kg of a 10 per cent guaiphenesin solution was investigated for the induction of recumbency in 15 horses; the addition of 1.6 mg/kg of ketamine was also evaluated in 15 horses and anaesthesia was maintained with halothane in oxygen. The horses became recumbent quickly and smoothly and they recovered quietly, with little ataxia. Tachycardia occurred after induction, but no other changes from pre-operative values were observed until halothane in oxygen had been given, when hypothermia, hypotension, bradypnoea, hyperoxaemia, respiratory acidosis and decreased respiratory minute volume developed. Horses given ketamine in addition to methotrimeprazine, midazolam and guaiphenesin were easier to intubate and recovered more quickly than horses receiving only methotrimeprazine, midazolam and guaiphenesin.

Environmental education and the health risk question: how do we educate the educators working with this theme?

Our society is presently seeing a trend of continuous increase of risk with severe consequences, especially those linked to environmental aspects. It has obligated us to reflect on this production and its effects, either positive or negative, and, after a long reflection, to think about the adopted model of civilization and the possibilities of changing such a model. The educational institution is among the social departments responsible for this revision process, since it represents one possibility to promote a more critical vision from society, providing it with tools needed for a more responsible action. However, schools are dominated by a traditional work, which does not allow for enough and proper attention to these relevant and current questions, and which involve a critical analysis of the conceptions and values established by our civilization, resulting in the present patterns of science-technology-society relations and their influence on the environment and health. Several research works have indicated a diversity of barriers that obstruct this necessary change. Since formal education plays an important role in the education of society for this theme, in this paper the possibilities and difficulty dealing with this problem are discussed, focusing on the question of teacher education, based on investigations related to teacher education programs for environmental education. The data collected show the urgency for introducing this theme in teacher training programs, taking into account the fact that educators have their own conceptions, values and attitudes that should be considered in these programs.

Interaction of mercury(II) with humic substances from the Rio Negro (Amazonas State, Brazil) by means of an ion exchange procedure

The aquatic humic substances (HS) investigated in this study with respect to their binding capability towards mercury(II) were isolated from the river Rio Negro, Amazonas State - Brazil, by means of the adsorbent XAD 8. Labile/inert fractions of inorganic Hg(II) complexes formed with these HS were characterized using an ion-exchange batch and column technique, respectively, based on Chelite S. This collector exhibits high Hg(II) distribution coefficients, Kd, up to the order of 104 decreasing, however, in the case of small Hg(II)/HS ratios (< 0.1 μg Hg(II) / mg HS). The influence of different complexation parameters (ratio of Hg(II)/HS, pH, contact time, complexing time) relevant for Hg(II) binding in aquatic environments was assessed. The Hg(II) lability in dissolved HS is mainly influenced by the mass ratio of Hg(II)/HS and the ageing of Hg(II)-HS species formed. This is particularly obvious in the case of low Hg(II) loading of HS where slow transformation processes of freshly formed Hg(II)-HS species significantly decrease their lability, leading to incomplete recoveries (< 20%) of the total Hg(II) bound to HS.

A simplified procedure for determination of clofentezine residues in fruits by liquid chromatography with UV detection

A rapid and sensitive method is described for the determination of clofentezine residues in apple, papaya, mango and orange. The procedure is based on the extraction of the sample with a hexane:ethyl acetate mixture (1:1, v/v) and liquid chromatographic analysis using UV detection. Mean recoveries from 4 replicates of fortified fruit samples ranged from 81% to 96%, with coefficients of variation from 8.9% to 12.5%. The detection and quantification limits of the method were of 0.05 and 0.1 mg kg-1, respectively.

An alternative procedure to decrease the dimension of the frequency dependent modal transformation matrices: Application in three-phase transmission lines with a vertical symmetry plane

The objective of this paper is to show an alternative representation in time domain of a non-transposed three-phase transmission line decomposed in its exact modes by using two transformation matrices. The first matrix is Clarke's matrix that is real, frequency independent, easily represented in computational transient programs (EMTP) and separates the line into Quasi-modes α, β and zero. After that, Quasi-modes α and zero are decomposed into their exact modes by using a modal transformation matrix whose elements can be synthesized in time domain through standard curve-fitting techniques. The main advantage of this alternative representation is to reduce the processing time because a frequency dependent modal transformation matrix of a three-phase line has nine elements to be represented in time domain while a modal transformation matrix of a two-phase line has only four elements. This paper shows modal decomposition process and eigenvectors of a non-transposed three-phase line with a vertical symmetry plane whose nominal voltage is 440 kV and line length is 500 km. © 2006 IEEE.
