Deficiência, cinema, imaginário e forma o docente
Maria Inês Naujorks,Daniela Corte Real,Alana Claudia Mohr
Revista Educa??o Especial , 2011, DOI: 10.5902/1984686x4361
Abstract: Neste artigo, pretendemos articular as rela es entre cinema, imaginário, deficiência e forma o docente, refletindo acerca das possibilidades de interven o/forma o pedagógica na perspectiva da educa o inclusiva. Entendendo o cinema como arte, comunica o, divers o e dispositivo transmissor de cultura, apostamos na potência deste artefato midiático como mediador das rela es que envolvem os diferentes sujeitos da educa o especial nas múltiplas instancias que submergem às rela es de ensino/aprendizagem. Achamos significativo retomar a ideia de cinema como recurso pedagógico potencializador da for a comunicativa e expressiva da linguagem audiovisual. Para tanto, é preciso pensar o cinema como dispositivo transmissor de cultura, o que exige, no campo educacional, o domínio de certo saber sobre arte que, por sua vez, movimenta os processo de forma o docente através da media o estética. A valoriza o do saber do cinema (REIS, 2005) se alia a esta outra configura o do que ousamos chamar de nova gramática da educa o especial na perspectiva inclusiva, que amplia os espa os de forma o, extrapola os limites das salas de aula e ressignifica os processos de leitura e de constru o de conhecimento docente. Palavras-chave: Deficiência; Cinema; Imaginário; Forma o docente.

Abstract: the purpose of this study was to determine, through the shear bond strength of in vitro tests, that the type of glass-ionomer cements (conventional or hybrid) and dentin depth (superficial or deep) are factors that may influence the adhesion of these materials to the dentin structure. specimens of two conventional glass-ionomer cements (vidrion r? - ss white and chelon fil?- espe) and a hybrid-glass ionomer cement (vitremer? - 3m) were separated in groups and prepared for the shear bond strength test. the results submitted to statistical analysis were (all values are in mpa): group i - vidrion r - superficial dentin 1.97 (± 0.56); deep dentin 3.15 (± 1.51); group ii - chelon fil - superficial dentin 2.43 (± 1.43); deep dentin 3.21 (± 0.89); and group iii - vitremer - superficial dentin 7.04 (± 2.04); deep dentin 10.30 (± 1.99). there were significant differences between dentin depth and type of materials

Abstract: Hydrological models to evaluate the impacts of climate change in the water resources sector require spatially correlated daily precipitation scenarios as model inputs. This paper presents a practical procedure for developing such precipitation scenarios using multisite stochastic weather models or generators conditional on large-scale daily circulation patterns, based on GCM-simulated future mean sea level pressure (MSLP) fields. The procedure is demonstrated on the basis of HadCM3 and HadAM3H simulations with an example for two river basins in the Iberian Peninsula. Changes in daily precipitation scenarios for the region generated by stochastic models are consistent with large-scale precipitation scenarios from direct GCM outputs; however, more localised characteristics have to be found from downscaled precipitation scenarios rather than from direct GCM outputs. This may imply that possible changes in downscaled precipitation reflect the underlying physics in GCMs, so that downscaled daily precipitation scenarios may be more suitable for impact models than the coarse GCM outputs.

Abstract: The purpose of this study was to determine, through the shear bond strength of in vitro tests, that the type of glass-ionomer cements (conventional or hybrid) and dentin depth (superficial or deep) are factors that may influence the adhesion of these materials to the dentin structure. Specimens of two conventional glass-ionomer cements (Vidrion Rregistered - SS White and Chelon Filregistered- Espe) and a hybrid-glass ionomer cement (Vitremerregistered - 3M) were separated in groups and prepared for the shear bond strength test. The results submitted to statistical analysis were (all values are in MPa): Group I - Vidrion R - superficial dentin 1.97 (± 0.56); deep dentin 3.15 (± 1.51); Group II - Chelon Fil - superficial dentin 2.43 (± 1.43); deep dentin 3.21 (± 0.89); and Group III - Vitremer - superficial dentin 7.04 (± 2.04); deep dentin 10.30 (± 1.99).

Abstract: THE IMPACT OF THE NORTH ATLANTIC OSCILLATION ON THE EUROPEAN CLIMATE AND RIVER FLOW OF THREE MAJOR IBERIAN RIVERS – The North Atlantic Oscillation (NAO) is the most dominant mode of atmospheric circulation variability over the entire Northern Hemisphere (NH) and has recently been shown to be related to climate over large regions of the NH, in particular, over the European and North American continents. Here, a multivariable analysis of the influence ofthe NAO on the climate of the North Atlantic and European sectors is presented using the 40 year (1958-97) reanalysis data set from National Centres for Environmental Prediction. Using high and low NAO index composites, anomaly fields of climate variables are then interpreted based on physical mechanisms associated with the anomalous mean flow (characterised by the surface wind field) and theanomalous eddy activity (characterised by the surface vorticity and the 500hPa storm track fields). It is shown that NAO-related temperature patterns are mainly controlled by the advection of heat by the anomalous mean flow. However, asymmetries between minimum and maximum temperatures, and more significantly, between positive and negative phases of NAO imply the importance of a different mechanism, namely the modulation of short wave and long wave radiation by cloud cover variations associated with the NAO. Furthermore, NAO influence over two different precipitation-related variables, namely, precipitation rate and precipitable water display different patterns. Precipitable water is shown to be strongly related to the corresponding anomaly fields of temperature while precipitation rate appears to be controlled by the surface vorticity field and associated strength of the tropospheric synoptic activity. Finally, we have assessed the impact of the NAO on winter river flow regimes for several different Portuguese rivers, including the three main international Iberian rivers, the Douro (north), the Tagus (centre) and the Guadiana (south). Results show that the large inter-annual variability of flow of these three rivers is largely modulated by the NAO. Such modulation, associated with the recent positive trend of the NAO index, might implicate a significant decrease of the available flow. This reduction can representan important hazard for the Portuguese economy due to its negative impact in agricultural yield and hydroelectric power production.

Abstract: Monoxenous trypanossomatids protozoa are not believed to cause in vivo infection in verte- brate hosts throughout their life cycle. However, there are reports mentioning some cases of HIV- positive patients who have presented opportunistic infections caused by these protozoa. Recently, we have demonstrated the in vitro infection of mouse dermal fibroblasts by these protozoa. The aim of the present work is to investigate the possibility of Crithidia deanei, a endosymbiont-bearing monoxenous trypanossomatid, infect BALB/c mice under or not Dexamethasone treatment. To attend it, distinct gro- ups of adult BALB/c mice were immunosuppressed with 50 mg/kg of Dexamethasone. This immunosuppressor was administered 24 hours before infection and daily, for 15 days after C. deanei inoculation. Control groups: C. deanei–inoculated animals but non-immuno- suppressed and non-inoculated animals but immunosuppressed were also used. Light Microscopy analysis revealed an infection process characterized by the presence of the trypanossomatid inside dermal cells in the groups studied. The experimental inoculation resulted in a non-lethal infection characterized by the presence of the trypanossomatid inside dermal cells in the normal BALB/c mice, but notably, in the C. deanei–inoculated immunosuppressed group. These preliminary results lead to the following conclusions: 1) C. deanei is able to infect normal BALB/c mice; 2) the immunosupressed mice seemed to be more susceptible to the C. deanei infection compared to the control group. Besides C. deanei in dexamethasone-immunosuppressed mice provides a useful model for studies of monoxenous trypanosomatids ‘in vivo’ infection, resembling that one presumably occurring in imunodeficient individuals with AIDS.
Kinetics and mechanism of hydrolysis of benzimidazolylcarbamates
Norberto, F. P.;Santos, S. P.;Iley, J.;Silva, D. B.;Corte Real, M.;
Journal of the Brazilian Chemical Society , 2007, DOI: 10.1590/S0103-50532007000100019
Abstract: synthesis of new 2-aminobenzimidazole-1-carbamates was accomplished by carbamoylation of 2-aminobenzimidazole using different substituted phenyl chloroformates. the aqueous hydrolysis of the new compounds was examined in the ph range 1-13 at 25 oc. the evaluated kinetic parameters led to the conclusion that up to ph 4 reaction proceeds by a bimolecular attack of water to the n-protonated substrate. this is the first time this behavior is described for carbamates, and can be ascribed to the higher basicity of the benzimidazolyl moiety when compared with the carbonyl oxygen. for higher values of ph, the results are consistent with a bac2 mechanism with nucleophilic catalysis, but while between ph 4 and ph 7 water acts as the nucleophile, for ph> 7 the hydroxide ion is the acting species.
Immunogold labeling and cerium cytochemistry of the enzyme ecto-5'-nucleotidase in promastigote forms of Leishmania species
Corte-Real, Suzana;Porrozzi, Renato;Meirelles, Maria de Nazareth Leal de;
Memórias do Instituto Oswaldo Cruz , 1993, DOI: 10.1590/S0074-02761993000300009
Abstract: we have applied both enzyme cytochemistry and immunological labeling techniques to characterize the enzyme 5'-nucleotidase (5'-nase), at the ultrastructural level, in promastigote forms of four leishmania species: leishmania amazonensis, leishmania mexicana, leishmania donovani and leishmania chagasi. the cerium phosphate staining was localized at the surface of the cell body, the flagellum and the flagellar pocket membranes of all the parasites studied. the immunogold labelling technique confirmed these results. in this report we localized 5'-nase in l. chagasi and l. amazonensis which have been implicated respectively in visceral and cutaneous forms of leishmaniasis. in addition, we confirmed the localization of this phosphomonoesterase in the other two species studied. the superior quality of the images, obtained with both methodologies, confirms that these parasites possess mechanisms capable of hydrolyzing nucleotide monophosphates, and that the expression of 5'-nase is associated with the outer surface of the plasma membrane.
