Published: October 2018

Introduction. Power parameters of the “rolling − equalchannel angular pressing” (ECA) combined process are studied. The work objective is to determine forces of rolling and pressing in the deformation by the combined method.Materials and Methods. The die strength calculation and the experiment on deformation of AISI 6063 aluminum samples were carried out. During the experiment, the force values were recorded using a strain-gauge station.Research Results. The strength analysis results show that this die design is suitable for creating an experimental stand of the “rolling − ECA-pressing” combined process, since the calculated safety margin is sufficient to implement the pressing under extreme conditions. The rolling forces at all stages of the deformation exceed the corresponding pressing forces, which is a necessary condition for the combined process. Discussion and Conclusions. The obtained results can be used in the design of experimental stands that implement the investigated combined process. Herewith, the given strain-gauge method for studying strength characteristics is suitable for the case of calibrated rolls.

"Minha história não é minha história. Ela é a história de uma geração" - A trajetória de uma militante dos movimentos sociais
Authors: Silva Vivian Da Veiga 
Published: October 2018

Apesar da abertura do campo historiográfico para novas temáticas e novas abordagens, construir uma história das mulheres ainda é um desafio e emerge como um campo marcado por silêncios e lacunas. Nesse sentido, podemos compreender a história oral como uma estratégia para acessar a memória de agentes históricos silenciados e negligenciados. O presente artigo tem como objetivo resgatar elementos referentes à importantes movimentos sociais ocorridos no Brasil a partir da década de 1960, utilizando como fio condutor os relatos de militância de Ana Maria Gomes, socióloga, docente da Universidade Federal de Mato Grosso do Sul, integrante do denominado Grupo de Osasco e de movimentos de resistência à ditadura militar e reconhecida pela sua expressiva atuação no movimento de mulheres.História das mulheres; movimentos sociais; militância

Published: October 2018

Copper, and its, alloys and composites (being the matrix), are broadly used in the electronic as well as bearing materials due to the excellent thermal and electrical conductivities it has.
In this study, powder metallurgy technique was used for the production of copper graphite composite with three volume perc ent of graphite. Processing parameters selected is (900) °C sintering temperature and (90) minutes holding time for samples that were heated in an inert atmosphere (argon gas). Wear test results showed a pronounced improvement in wear resistance as the percent of graphite increased which acts as solid lubricant (where wear rate was decreased by about 88% as compared with pure Cu). Microhardness and compressive strength increased (about 8% and 16%, for each of them) and reached to the maximum values at 1% graphite percentage as compared with pure Cu, then it decreased after that critical graphite concentration. Microstructure test indicated that the dark region in the copper matrix was increased as the percent of graphite increased and the reinforcement particles were homogeneously distributed which means that the powder metallurgy technique is suitable for such task.

There was a statistically positive correlation between waist circumference, body mass index and random blood sugar . Therefore, waist circumference, non-invasive techniques has a good correlation with BMI and therefore abdominal obesity is a predictor of diabetes.Int. J. Appl. Sci. Biotechnol. Vol 6(3): 274-278
Territorial Expanded Cinema in the Neo-liberal City: Curating Multiscreen Environments in Yonge-Dundas Square and Quartier des spectacles
Authors: Melzer Zach 
Published: October 2018

L’auteur s’intéresse au Yonge-Dundas Square de Toronto et au Quartier des spectacles de Montréal à titre d’exemples contemporains de cinéma élargi — ce qu’il appelle le cinéma élargi territorial. Redéveloppés par des partenariats public-privé et assujettis à leurs pouvoirs réglementaires, les deux créatures municipales qui gèrent ces espaces ont codifié des environnements multimédia et multi-écrans inspirés du néolibéralisme. Alors que le conseil d’administration du Yonge-Dundas Square s’est donné pour mission de mettre en lumière la dimension commerciale de la ville, le partenarial du Quartier des spectacles s’est employé à promouvoir un urbanisme axé sur la célébration « de la culture et des arts ». Ces différences dans les mandats se manifestent non seulement dans le contenu affiché, mais également dans l’organisation des écrans et des espaces, ainsi que dans la sorte des technologies employées. Contrairement aux discours nationaliste et internationaliste qui charpentent le cinéma élargi dans d’autres contextes, le cinéma élargi territorial se caractérise par la privatisation des espaces urbains.

La presse régionale en Tunisie: une presse de territoire marginalisée
Authors: Smati Nozha 
Published: October 2018

La presse régionale privée en Tunisie, rencontre aujourd'hui des contraintes financières, humaines et techniques qui handicapent son évolution et nuisent à sa visibilité dans l'espace médiatique tunisien. Ces contraintes menacent sa régularité, voire son existence, et influencent par conséquent ses contenus.
En comparaison avec des éléments relatifs à la réussite de l'expérience de la presse régionale française il s'avère que la presse régionale tunisienne est marginalisée et
demeure à la recherche d'une identité. Contrairement à
l'expérience française qui a pu se situer comme presse
de territoire et a réussi à fidéliser son lectorat, la presse régionale en Tunisie peine à se positionner comme une presse de proximité crédible et indépendante et à jouer le rôle d'animateur de l'espace public régional.
Autophagy Involved in Antiviral Activity of Sodium Tanshinone IIA Sulfonate against Porcine Reproductive and Respiratory Syndrome virus Infection in vitro

Published: October 2018

Background In previous research, we have demonstrated that sodium tanshinone IIA sulfonate (STS) has anti-porcine reproductive and respiratory syndrome virus (PRRSV) activity, but whether autophagy is involved in this process is still unknown. In this study, the autophagy effect of STS against PRRSV infection was investigated in vitro. Methods Quantitative real-time PCR (qRT-PCR) and western blot was used to evaluate the inhibition ability of STS on the mRNA expression levels on cell autophagy genes, that is Beclin1, ATG5 and ATG7. Simultaneously, the effect of STS on N protein/gene expression was assessed by indirect immuno-fluorescence assay (IFA), qRT-PCR and western blot. Results The results indicated that STS inhibits autophagy induced by PRRSV. In addition, STS effectively suppresses PRRSV's N protein replication and N gene expression in Marc-145 cells infected with PRRSV in a time-dependent manner. Conclusions Our results suggest that STS exhibits anti-PRRSV activity in vitro by suppressing autophagy-related genes, which may provide a theoretical basis for further pharmacological agent development regarding PRRSV infection.

Published: October 2018

Objective.Forced vital capacity (FVC) and DLCO are used for screening of systemic sclerosis–associated interstitial lung disease (SSc-ILD). The study purpose was to determine the sensitivity, specificity, and negative predictive value (NPV) (proportion of true negative screening tests) of FVC and DLCO thresholds for SSc-ILD on chest high-resolution computed tomography (HRCT) scans.Methods.Patients fulfilling American College of Rheumatology 2013 SSc criteria with a chest HRCT scan and pulmonary function tests (PFT) were studied. A thoracic radiologist quantified radiographic ILD. Optimal FVC and DLCO % predicted thresholds for ILD were identified using receiver-operating characteristic curves. The FVC and DLCO combinations with greatest sensitivity and specificity were also determined. Subanalysis was performed in patients with positive Scl-70 autoantibodies.Results.The study included 265 patients. Of 188 (71%) with radiographic ILD, 59 (31%) had “normal” FVC (≥ 80% predicted), and 65 out of 151 (43%) had “normal” DLCO (≥ 60% predicted). FVC < 80% (sensitivity 0.69, specificity 0.73), and DLCO < 62% (sensitivity 0.60, specificity 0.70) were optimal thresholds for radiographic SSc-ILD. All FVC and DLCO threshold combinations evaluated had NPV < 0.70. The NPV for radiographic ILD for FVC < 80% was lower in patients with positive Scl-70 autoantibody (NPV = 0.05) compared to negative Scl-70 autoantibody (NPV = 0.57).Conclusion.Radiographic ILD is prevalent in SSc despite “normal” PFT. No % predicted FVC or DLCO threshold combinations yielded high NPV for SSc-ILD screening. “Normal” FVC and DLCO in patients with SSc, especially those with positive Scl-70 autoantibodies, should not obviate consideration of HRCT for ILD evaluation.

Objective.We sought to identify predictors of mortality and cardiopulmonary hospitalizations in patients at risk for pulmonary hypertension (PH) and enrolled in PHAROS, a prospective cohort study to investigate the natural history of PH in systemic sclerosis (SSc).Methods.The at-risk population for PH was defined by the following entry criteria: echocardiogram systolic pulmonary arterial pressure > 40 mmHg, or DLCO < 55% predicted or ratio of % forced vital capacity/%DLCO > 1.6, measured by pulmonary function testing. Baseline clinical measures were evaluated as predictors of hospitalization and death between 2005 and 2014. Cox proportional hazards models were censored at date of PH onset or latest study visit and adjusted for age, sex, race, and disease duration.Results.Of the 236 at-risk subjects who were followed for a median of 4 years (range 0.4–8.5 yrs), 35 developed PH after entering PHAROS (reclassified as PH group). In the at-risk group, higher mortality was strongly associated with male sex, low %DLCO, exercise oxygen desaturation, anemia, abnormal dyspnea scores, and baseline pericardial effusion. Risks for cardiopulmonary hospitalization were associated with increased dyspnea and pericardial effusions, although PH patients with DLCO < 50% had the highest risk of cardiopulmonary hospitalizations.Conclusion.Risk factors for poor outcome in patients with SSc who are at risk for PH were similar to others with SSc-PH and SSc-pulmonary arterial hypertension, including male sex, DLCO < 50%, exercise oxygen desaturation, and pericardial effusions. This group should undergo right heart catheterization and receive appropriate intervention if PH is confirmed.
