O difícil caminho da reforma: A polícia e os limites do processo de reforma pós-redemocratização

A transition of Brazil from a juridico-political system of exception to a democracy was accompanied by several legal and institutional reform processes, aimed at the gradual elimination of so-called authoritarian rubble and the implementation of instruments of the democratic system, based on recognized citizenship and justice. However, to this day the extent and effects of those reforms can be questioned, especially in light of the increased public demand for justice and citizenship. The article The Difficult Path to Reform: The Police and Limits of the Post-Redemocratization Reform Process shows that the route to reform, above all in the sphere of police agencies, is a tortuous one, with an extensive agenda of problems and solutions, demanding research on the part of academics in order to form an understanding of the resistance to change and to new paradigms that define the public security agenda.

Desempenho e digestibilidade de componentes nutritivos de dietas contendo subprodutos de leaginosas na alimentação de cordeiros

The aim of this work was evaluate introduction of byproducts of oleaginous in lambs feeding. Diets were composed for 30% of Tifton hay and 70% of concentrate based on corn grain, soybean meal, soybean cake, sunflower cake and peanut cake, limestone and mineral mixture, as dites: FS - control with soybean meal, TS - soybean cake as part of the concentrate, TG sunflower cake as part of the concentrate and TA - peanut cake as part of the concentrate. For performance evaluating 24 Santa Ines lambs with initial age and weight of 70 days and 19 +/- 2 kg, according to a completely randomized design. For digestive evaluate, weight Santa Ines sheep with initial age and weight of 70 days and 16 +/- 1.2 kg, adapted to the use of bag, for collect feces. Animals were distributed in a replicated 4 x 4 Latin Square and means were compared by Tukey's test with 5% significance level. By the performance trial, duration of confinement, weight gain, fed conversion and the dry matter intake were not affected (P>0,05), with averages of 54.29 days, 259 g/day, 4.29 kg of DM/kg and 1.32 kg/day, respectively. There were no difference P>0,05) for intake DM, OM, CP, CT and CE among diets, digestibility trial with averages of 76.23; 74.47; 76.44; 41.12; 73.00 and 93.00%, respectively. There were no differences for digestibility DM, OM, CP, ADF, CT and NCF. The partial substitution of the soybean meal for byproducts of oleaginous was a good proteic alternative in the feeding of lambs.

Alveolar ridge and maxillary sinus augmentation using rhBMP-2: a systematic review

Purpose: The aim of this systematic review was to evaluate clinical and safety data for recombinant human bone morpho-genetic protein-2 (rhBMP-2) in an absorbable collagen sponge (ACS) carrier when used for alveolar ridge/maxillary sinusaugmentation in humans.Materials and Methods: Clinical studies/case ser ies published 1980 through June 2012 using rhBMP-2/ACS were searched.Studies meeting the following criteria were considered eligible for inclusion: >10 subjects at baseline and maxillary sinus oralveolar ridge augmentation not concomitant with implant placement.Results: Seven of 69 publications were eligible for review. rhBMP-2/ACS yielded clinically meaningful bone formationfor maxillary sinus augmentation that would allow placement of regular dental implants without consistent differencesbetween rhBMP-2 concentrations. Never theless, the statistical analysis showed that sinus augmentation following autog-enous bone graft was significantly greater (mean bone height: 1.6 mm, 95% CI: 0.5–2.7 mm) than for rhBMP-2/ACS(rhBMP-2 at 1.5 mg/mL). In extraction sockets, rhBMP-2/ACS maintained alveolar ridge height while enhancing alve olarridge width. Safety reports did not represent concerns for the proposed indications.Conclusions: rhBMP-2/ACS appears a promising alternative to autogenous bone grafts for alveolar ridge/maxillary sinusaugmentation; dose and carrier optimization may expand its efficacy, use, and clinical application.

Measuring Aeolian Saltation: A Comparison of Sensors

SHERMAN, D.J.; LI, B.; FERRELL E.J.; ELLIS, J.T.; COX, W.D.; MAIA, L.P., and SOUSA, P.H.G.O., 2011. Measuring Aeolian Saltation: A Comparison of Sensors. In: Roberts, T.M., Rosati, J.D., and Wang, P. (eds.), Proceedings, Symposium to Honor Dr. Nicholas C. Kraus, Journal of Coastal Research, Special Issue, No. 59, pp. 280-290. West Palm Beach (Florida), ISSN 0749-0208. We report the results of field experiments designed to compare four types of aeolian saltation sensors: the Safire; the Wenglor (R) Particle Counter; the Miniphone; and the Buzzer Disc. Sets of sensors were deployed in tight spatial arrays and sampled at rates as fast as 20 kHz. In two of the three trials, the data from the sensors are compared to data obtained from sand traps. The Miniphone and the Buzzer Disc, based on microphone and piezoelectric technologies, respectively, produced grain impact counts comparable to those derived from the trap data. The Satire and the Wenglor (R) Particle Counter produce count rates that were an order of magnitude too slow. Satires undercount because of their large momentum threshold and because its signal is saturated at relatively slow transport rates. We conclude that the Miniphone and the Buzzer Disc are appropriate for deployment as grain counters because their small size allows them to be installed in closely-spaced sets.

Oestrogen receptor beta in adenoid cystic carcinoma of salivary glands

Aims: This study aimed to describe the expression of oestrogen receptor (ER)alpha, ER beta and aromatase in salivary gland adenoid cystic carcinoma (ACC). Methods and results: ER alpha, ER beta and aromatase expression was analysed by immunohistochemistry in tissue microarray blocks from 38 cases of ACC and seven normal salivary glands. The intracellular localization and amount of total protein expression were investigated by immunofluorescence and western blotting in an ACC cell line. Western blotting analysis showed overexpression of ER alpha, ER beta and aromatase in the ACC cell line; however, with immunofluorescence, only ER beta was shown to be expressed in the nucleus. Immunohistochemistry revealed positive nuclear expression of ER beta, positive cytoplasmic expression of aromatase and a lack of ER alpha expression as compared with normal salivary glands. Conclusions: The nuclear expression of ER beta indicates that oestrogen may be active in ACC and possibly able to mediate E2-targeted gene transcription. This study strongly suggests that ER beta may be involved in tumour progression, playing a role in tumour development, and thus corroborating the indication for ER antagonists in the clinical control of ACC. This study opens a new perspective on the potential use of anti-oestrogens and aromatase inhibitors as therapeutic agents against ACC.

Magnetic Ionic Liquids Produced by the Dispersion of Magnetic Nanoparticles in 1-n-Butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (BMI.NTf2)

This paper reports on the advancement of magnetic ionic liquids (MILs) as stable dispersions of surface-modified gamma-Fe2O3, Fe3O4, and CoFe2O4 magnetic nanoparticles (MNPs) in a hydrophobic ionic liquid, 1-n-butyl 3-methylimidazolium bis(trifluoromethanesulfonyl)imide (BMI.NTf2). The MNPs were obtained via coprecipitation and were characterized using powder X-ray diffraction, transmission electron microscopy, Raman spectroscopy and Fourier transform near-infrared (FT-NIR) spectroscopy, and magnetic measurements. The surface-modified MNPs (SM-MNPs) were obtained via the silanization of the MNPs with the aid of 1-butyl-3[3-(trimethoxysilyl)propyl]imidazolium chloride (BMSPI.Cl). The SM-MNPs were characterized by Raman spectroscopy and Fourier trail: form infrared attenuated total reflectance (FTIR-ATR) spectroscopy and by magnetic measurements. The FTIR-ATR spectra of the SM-MNPs exhibited characteristic absorptions of the imidazolium and those of the Fe-O-Si-C moieties, confirming the presence of BMSPI.Cl on the MNP surface. Thermogravimetric analysis (TGA) showed that the SM-MNPs were modified by at least one BMSPI.Cl monolayer. The MILs were characterized using Raman spectroscopy, differential scanning calorimetry (DSC), and magnetic measurements. The Raman and DSC results indicated an interaction between the SM-MNPs and the IL. This interaction promotes the formation of a supramolecular structure close to the MNP surface that mimics the IL structure and is responsible for the stability of the MIL. Magnetic measurements of the MILs indicated no hysteresis. Superparamagnetic behavior and a saturation magnetization of similar to 22 emu/g could be inferred from the magnetic measurements of a sample containing 50% w/w gamma-Fe2O3 SM-MNP/BMI-NTf2.

Serological survey on Ehrlichia sp. among dogs in the central region of Rio Grande do Sul

A serological survey on Ehrlichia canis was conducted among dogs in the central area of the state of Rio Grande do Sul, where the tick Rhipicephalus sanguineus is a common parasite of dogs. Out of a total of 316 dogs attended at the veterinary teaching hospital in the municipality of Santa Maria, only 14 (4.43%) reacted positively to E. canis antigens in the indirect immunofluorescence assay, with the following endpoint titers: 80 (three dogs), 160 (five), 320 (four), 640 (one) and 1280 (one). Like in previous studies in other regions of the state of Rio Grande do Sul, only a very small portion of the dogs in Santa Maria presented antibodies reactive to E. canis, even though canine infestations due to R. sanguineus are very common in this study region. These results contrast with other regions of Brazil, where E. canis is endemic among canine populations, with seropositivity values generally higher than 30%. Genetic differences among the R. sanguineus populations in South America might be implicated in these contrasting results.

O BÔNUS PROFESSOR

Esta dissertação de mestrado fundamenta-se na pesquisa qualitativa e tem como objetivo a análise da ideologia do Bônus Mérito, instituído para os servidores públicos do Estado de São Paulo no início da década de 2000. Limitamos nossa análise à docência do ensino fundamental. As transformações econômicas, ocorridas a partir da década de 1980 nos países altamente industrializados, passam a exigir a melhoria do ensino dos países emergentes. Em conseqüência, a educação volta a ser revalorizada e a ter papel de destaque para os investimentos externos, através das agências e órgãos internacionais tais como: Bird, Unesco, Banco Mundial, PNUD. A ideologia do Bônus Mérito é um exemplo típico de transferência para o âmbito educacional de modelos de gestão das empresas privadas. Esta ideologia afeta a atividade docente, cujo desempenho é, doravante medido através de pontos, divisão de trabalho, impessoalidade, requalificação profissional etc. Efetivamente, em meio à globalização da economia e ao contexto político neoliberal, o governo do Estado de São Paulo optou, no período analisado, por seguir as determinações das grandes potências econômicas. O repasse de recursos financeiros recebidos pelo Estado para a efetivação das mudanças educacionais (diminuição da evasão, universalização das matrículas, aumento do número de alunos com aprovação) esteve condicionado às exigências das referidas agências e órgãos internacionais. Como é demonstrado neste trabalho, essa política relega a segundo plano o docente e sua prática de ensino. A explicitação do fundamento da ideologia do bônus no interior da escola pública visa demonstrar, em primeiro lugar, que o Bônus Mérito é um aparente benefício ao docente; e, em segundo lugar, que sua implantação não é outra coisa que o domínio econômico sobre o projeto educacional.
