A oficina terapêutica como intercessão em problemáticas de sujeitos constituídos por foraclusão

O presente estudo é uma reflexão crítica sobre um estágio realizado para pensar o dispositivo Oficina na Atenção Psicossocial (CAPS), levantando, a partir da teoria psicanalítica lacaniana, questões que permitiram desenvolver um trabalho sobre o laço social de Lacan para refletir a posição de estagiários e usuários dentro da oficina e problematizar a melhor maneira de trabalhar quando tratamos de sujeitos constituídos pela foraclusão. A forma de trabalhar o sofrimento mental também é discutida a partir da clínica ampliada, que coloca a doença entre parênteses para enxergar o sujeito. A criação de uma oficina, destinada a sujeitos constituídos pela foraclusão, trabalha com a hipótese de reestruturação psíquica através da criação artística. Funcionaria como delírio para a saída do desmoronamento foraclusivo e na diminuição do gozoOutro. Considera-se a dimensão da enunciação, sempre atenta ao surgimento de significantes, com o objetivo de dar maior suporte aos usuários da instituição. O Dispositivo Oficina seria o lugar onde se realizaria esta importante forma de subjetivação.

Structural organization in leaf blade and sheath of elephant-grass cultivars (Pennisetum purpureum Schum. - POACEAE).

Elephant-grass is known as a great feed to dairy and beef cattle at tropical regions. Its agricultural aspects have been very observed. However, its botanical, mainly anatomical characteristics, are few studied. The objective of this work was to investigate the anatomical changes occurred in leaves (leaf blades and sheaths) of three elephant-grass cultivars (Pennisetum purpureum Schum. cultivar Roxo, EMPASC 307 Testo and EMPASC 309 Areia) at three stages of physiological maturity (4, 8 and 16 weeks after sprouting). In general, the three cultivars presented similar anatomy. A unique feature, the presence of aerenchyma was found in the leaf sheath of all three cultivars, at the second harvest (a weeks).

Stem anatomy of Pennisetum purpureum schum. (Poaceae) cultivars

Elephant-grass is known like a great feed to dairy and beef cattle al tropical regions. Its agricultural aspects have been very observed. However, its botanical, mainly anatomical characteristics are few studied. The objective of this work was to investigate the anatomical changes occurred in stems of three elephant-grass cultivars (ROXO, EMPASC 307 TESTO and EMPASC 309 AREIA) at three stages of plant development (4, 8 and 16 weeks after sprouting). The anatomical features were similar among cultivars. When stems were young (4 weeks), a disorganization of vascular bundles were detected. However, at 8 weeks stage the were organized as a definitive form. Was observed a magnified of lignification as the stems age, mainly caused by the increased of bundles sheaths that surrounds all vascular bundles.

Surface modification of Ti dental implants by Nd: YVO4 laser irradiation

Surface modifications have been applied in endosteal bone devices in order to improve the osseointegration through direct contact between neoformed bone and the implant without an intervening soft tissue layer. Surface characteristics of titanium implants have been modified by addictive methods, such as metallic titanium, titanium oxide and hydroxyapatite powder plasma spray, as well as by subtractive methods, such as acid etching, acid etching associated with sandblasting by either AlO2 or TiO2, and recently by laser ablation. Surface modification for dental and medical implants can be obtained by using laser irradiation technique where its parameters like repetition rate, pulse energy, scanning speed and fluency must be taken into accounting to the appropriate surface topography. Surfaces of commercially pure Ti (cpTi) were modified by laser Nd:YVO4 in nine different parameters configurations, all under normal atmosphere. The samples were characterized by SEM and XRD refined by Rietveld method. The crystalline phases alpha Ti, beta Ti, Ti6O, Ti3O and TiO were formed by the melting and fast cooling processes during irradiation. The resulting phases on the irradiated surface were correlated with the laser beam parameters: the aim of the present work was to control titanium oxides formations in order to improve implants osseointegration by using a laser irradiation technique which is of great importance to biomaterial devices due to being a clean and reproducible process.

Inequalities in access to education and healthcare

The burden of disease is borne by those who suffer as patients but also by society at large, including health service providers. That burden is felt most severely in parts of the world where there is no infrastructure, or foreseeable prospects of any, to change the status quo without external support. Poverty, disease and inequality pervade all the activities of daily living in low-income regions and are inextricably linked. External interventions may not be the most appropriate way to impact on this positively in all circumstances, but targeted programmes to build social capital, within and by countries, are more likely to be sustainable. By these means, basic oral healthcare, underpinned by the primary healthcare approach, can be delivered to more equitably address needs and demands. Education is fundamental to building knowledge-based economies but is often lacking in such regions even at primary and secondary level. Provision of private education at tertiary level may also introduce its own inequities. Access to distance learning and community-based practice opens opportunities and is more likely to encourage graduates to work in similar areas. Recruitment of faculty from minority groups provides role models for students from similar backgrounds but all faculty staff must be involved in supporting and mentoring students from marginalized groups to ensure their retention. The developed world has to act responsibly in two crucial areas: first, not to exacerbate the shortage of skilled educators and healthcare workers in emerging economies by recruiting their staff; second, they must offer educational opportunities at an economic rate. Governments need to lead on developing initiatives to attract, support and retain a competent workforce.

Faunal analysis of the species Anastrepha in the fruit growing complex Gaviao River, Bahia, Brazil

Besides being considered the greatest pests of fruit growing, fruit flies constitute a large obstacle to the growth of the exportation of fresh fruit. Knowledge of the structure of fruit fly communities is of great importance to the bioecological studies of these insects, but there is a lack of information about the faunistic composition of fruit flies in Brazil. The objective of this work was to analysis the composition of the species of Anastrepha, in eleven mango orchards of the fruit growing complex Gaviao River, Bahia, Brazil. These studies were done in 2004 and 2005, in Anage, Caraibas and Belo Campo town, 23 McPhail traps, which collected 798 female fruit flies from the genus Anastrepha. The structure of these communities was evaluated in each orchard by means of faunistic indexes frequency, constancy, dominance, diversity and similarity. The number of species varied from four to eight in each orchard; and the following species was recorded: Anastrepha fraterculus (Wiedemann), Anastrepha obliqua (Macquart), Anastrepha dissimilis Stone, Anastrepha amita Zucchi, Anastrepha distincta Greene, Anastrepha pickeli Lima. Anastrepha sororcula Zucchi and Anastrepha zenildae Zucchi. The most frequent and dominant species were A. fraterculus and A. obliqua. The indexes of diversity varied from 1.01 to 1.62. In general, the similarity between orchards was high (above 55.0%). We observed the formation of groups, one constituted by Frutvale, Carlan, Santa Clara and Panorama orchards; another composed of Cofet, Campo Gaviao and Ouro Verde and a third group formed by Boa Vista orchard. Barra da Onca and Arruda are distinguished from other orchards.

Bayesian and multivariate methods applied to favorability quantification in recôncavo Basin and Ribeira Belt, Brazil

A methodology to define favorable areas in petroleum and mineral exploration is applied, which consists in weighting the exploratory variables, in order to characterize their importance as exploration guides. The exploration data are spatially integrated in the selected area to establish the association between variables and deposits, and the relationships among distribution, topology, and indicator pattern of all variables. Two methods of statistical analysis were compared. The first one is the Weights of Evidence Modeling, a conditional probability approach (Agterberg, 1989a), and the second one is the Principal Components Analysis (Pan, 1993). In the conditional method, the favorability estimation is based on the probability of deposit and variable joint occurrence, with the weights being defined as natural logarithms of likelihood ratios. In the multivariate analysis, the cells which contain deposits are selected as control cells and the weights are determined by eigendecomposition, being represented by the coefficients of the eigenvector related to the system's largest eigenvalue. The two techniques of weighting and complementary procedures were tested on two case studies: 1. Recôncavo Basin, Northeast Brazil (for Petroleum) and 2. Itaiacoca Formation of Ribeira Belt, Southeast Brazil (for Pb-Zn Mississippi Valley Type deposits). The applied methodology proved to be easy to use and of great assistance to predict the favorability in large areas, particularly in the initial phase of exploration programs. © 1998 International Association for Mathematical Geology.

Padrão de sensibilidade de cepas de Enterobacter spp isoladas na região de Presidente Prudente - SP

Enterobacter spp. are considered important causing agents of infection, specially in hospitalized individuals. The natural resistance of these microorganisms and the great facility to develop resistance to new antimicrobial agents make this genus an important object of study. In this work, 176 strains isolated from various clinical samples were used from hospitalized patients (University Hospital Domingos Leonardo Cerávolo) and from clinic patients (Clinical Laboratory from Unoeste), both situated in Presidente Prudente - SP. E. cloacae (78.9%), E. aerogenes (7.9%) and E. (pantoea) agglomerans (3.9%) were the ones more frequently isolated. Eleven antimicrobial agents were tested by the disk diffusion method and around 90% of the strains presented resistance to the cephalotin, ampicillin and cefaclor. Strains of E. (pantoea) agglomerans presented wide profile of sensibility However one strain of E. cloacae presented resistance to all the antimicrobial agents. The antimicrobial agents with greater inhibitory activity were imipenem and cefepime, for this reason these antimicrobial agents could be the treatment of choice in emergencial therapeutic. This emergencial therapy can be applied with relative security, whereas the data obtained in this study show homogeneity in the profile of sensibility to these antimicrobial agents, independent of the infection site and from the isolated species. The ESBL enzyme could not be detected in no one of the strains by the double diffusion test.
