title: Temporal trend of leprosy in a region of high endemicity in the Brazilian Northeast

description: ABSTRACT Objective: to analyze the temporal trend and epidemiological patterns of leprosy indicators in Sobral, a municipality countryside of the state of Ceará, from 2001 to 2016. Method: a time series study based on data from the Department of Informatics of the Unified Health System. The time trend analysis was performed using the join point regression model. Results: There were 2,220 new cases of leprosy in Sobral from 2001 to 2016. Of these, 158 (7.2%) in children younger than 15 years of age, the proportion of new male cases was 52.8% (1,162), cases with grade 2 were 7.0% (156), and proportion of cases diagnosed by contact examination 5.7% (126). Final considerations: leprosy remains hyperendemic in adults and children, demonstrating the character of neglected disease. Analysis of the temporal trend allowed to verify that the instability in the detection coefficients, reflect operational problems in the organization of the services

title: Phylogeography of msp4 genotypes of Anaplasma marginale in beef cattle from the Brazilian Pantanal

description: Abstract The msp4 gene of A. marginale is unicodon, stable and mostly homogeneous, being considered as a useful marker for phylogeographic characterization of this bacterium. The objective of this work was to analyze the phylogeography of A. marginale based on the msp4 gene in beef cattle from the Brazilian Pantanal, compared to those found in other regions worldwide. The blood samples investigated were collected from 400 animals (200 cows and 200 calves) reared in five extensive breeding farms in this region. The results indicated that of the evaluated samples, 56.75% (227/400) were positive for A. marginale based on the msp1β gene by quantitatitve PCR (qPCR), while 8.37% (19/227) were positive for the msp4 gene in the conventional PCR. In the Network distance analysis, 14 sequences from the Brazilian Pantanal were grouped into a single group with those from Thailand, India, Spain, Colombia, Parana (Brazil), Mexico, Portugal, Argentina, China, Venezuela, Australia, Italy and Minas Gerais (Brazil). Among 68 sequences from Brazil and the world, 15 genotypes were present while genotype number one (#1) was the most distributed worldwide. Both Splitstree and network analyses showed that the A. marginale msp4 sequences detected in beef cattle from the Brazilian Pantanal showed low polymorphism, with the formation of one genogroup phylogenetically related to those found in ruminants from South and Central America, Europe, and Asia.

title: Simulation and Design of a Bandpass Filter Based on Substrate Integrated E-Plane Waveguide

description: Abstract This paper presents a bandpass filter based on a substrate integrated E-plane waveguide (SIEW) structure for wireless applications, at X-band. The SIEW geometry allows the development of new horizontally polarized filter topologies, unlike filter structures based on substrate integrated waveguide (SIW), which present vertical polarization (perpendicular to the ground plane). The simulation of the proposed SIEW filter is carried out using Ansoft HFSS software. To evaluate the performance of the proposed structure, the frequency behaviors of the scattering parameters are obtained for a horizontally polarized excitation. In the simulation, analyses are performed for the lossless and lossy (dielectric and metallic) cases, in order to compare the obtained results. The SIEW filter is fabricated and measured using a vector network analyzer (VNA). Measurement results are in agreement with simulation ones, validating the proposed filter design and topology. The fabricated prototype resonates at 10.54 GHz, with a bandwidth of 1.20 GHz, defined for a -3 dB transmission coefficient reference level. The SIEW filter structure is easy to design and manufacture and can be used in wireless communications systems that require components with ease integration into other planar structures.

title: Production and characterization of metallic Cu-Sn alloy coatings in electrolytic bath containing glycine: preliminary exp

description: ABSTRACT The problems related to corrosion are frequent and may occur in many areas, such as the chemical, petrochemical, naval, civil construction and automobile industries, among other productive sectors. Therefore, corrosion prevention methods should be employed to avoid loss of materials and the use of metallic coatings has served well for this purpose. The production of metallic coatings allows a modification on the substrate surface leading to the formation of a functional material that presents the desired properties and characteristics, in this case, corrosion resistance. However, these coatings are generally produced using toxic cyanide-based baths, which increases the cost of the process due to further treatment of the generated wastes. The present work proposes an initial study aiming at producing of Cu-Sn alloy coatings, with anticorrosive properties, originated from a less aggressive electrolytic bath, presenting different copper and tin ionic concentrations. The coatings were electrodeposited on carbon steel substrate using an acidic electrolyte containing CuCl2, SnCl2 and glycine. These coatings were further characterized by scanning electron microscopy (SEM), X-ray spectroscopy energy dispersive (EDS), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. The results of EIS showed that the films produced with higher copper contents presented an increase in the values of the charge transfer resistance (Rct). However, the polarization experiments showed that these films did not act as protective coatings. The morphological analysis evidenced the formation of porous coatings, which may explain their poor electrochemical behavior.

title: Spatial analysis on tuberculosis and the network of primary health care

description: ABSTRACT Objective: to analyze the spatial distribution of new cases of tuberculosis compared to the location of the Primary Healthcare Units that performed the compulsory notification. Method: ecological study conducted in Belém, Pará, with 5,294 new cases of tuberculosis notified to Sistema de Informação de Agravos de Notificação for the period from 2010 to 2014. The cases were georeferenced using the software applications ArcGis 10.2 and TerraView 4.2.2. The techniques of Kernel density and global Moran geostatistics were used. Results: the incidence of tuberculosis cases did not vary significantly between the years studied, however there was a variation in incidence between neighborhoods. Health units that exhibited higher number of notifications can suffer great influence of migration from nearby neighborhoods. Conclusion: the spatial dynamics of tuberculosis associated with health services allows to know the areas with increased risk of tuberculosis and the density of notifications of health units.

title: Anthelmintic effect of Cymbopogon citratus essential oil and its nanoemulsion on sheep gastrointestinal nematodes

description: Abstract The anthelmintic resistance stimulated the search for strategies for controlling gastrointestinal nematodes, including the use of free essential oils or its nanoemulsion. This study evaluated the anthelmintic efficacy of Cymbopogon citratus essential oil (CcEO) and C. citratus essential oil nanoemulsion (CcEOn). Pysicochemical analyses were performed. The in vitro effect was determined using the egg hatch test (EHT) on Haemonchus contortus and in vivo effect was evaluated in sheep infected with gastrointestinal nematodes. The animals were treated with CcEO (500 mg/kg) or CcEOn (450 mg/kg) for the fecal egg count (FEC) and the determination of worm burden. The main component of CcEO was citral. The CcEO content in the nanoemulsion was 20% (v/v), and the mean particle size was 248 nm. In EHT, CcEO and CcEOn (1.25 mg/mL) inhibited larval hatching by 98.4 and 97.1%, respectively. Three animals treated with CcEO died whereas in the group treated with CcEOn one animal died. The FEC and total worm burden of the treated groups did not differ from the negative control (p&gt;0.05). The CcEOn showed efficacy only on H. contortus (p&lt;0.05). In conclusion, nanoencapsulation reduced toxicity and increased efficacy on H. contortus.

title: Ultrasound Evaluation of the Cervix to Predict Failed Labor Induction

description: Abstract Objective Labor induction does not always result in vaginal delivery, and can expose both the mother and the fetus to the risks inherent to the induction procedure or a possible cesarean section. Transvaginal sonography (TVS) of the cervix is a useful tool to predict prematurity; in the present study, this tool was used to evaluate postterm induction. Methods We evaluated the ultrasound characteristics of the cervix (cervical length, cervical funneling, internal os dilation, the presence or absence of the cervical gland area [CGA], and the morphological changes of the cervix as a result of applying fundal pressure) before the onset of labor induction among women with postterm pregnancy to identify the possible predictors of failed labor induction. The Bishop score (BS) was used for comparison purposes. Three groups were evaluated: successful versus unsuccessful induction; vaginal delivery versus cesarean delivery (excluding cases of acute fetal distress [AFD]); and vaginal delivery versus cesarean delivery (including cases of AFD). A fourth group including only the primiparous women from the three previous groups was also evaluated. Results Based on the studied characteristics and combinations of variables, a cervical length ≥ 3.0 cm and a BS ≤ 2 were the best predictors of induction failure. Conclusion Although TVS is useful for screening for induction failure, this tool should not be used as an indication for cesarean section.

title: ARTICLE - OPEN-AIR SCHOOL OF SÃO PAULO ESCOLA DE APLICAÇÃO AO AR LIVRE DE SÃO PAULO

description: ABSTRACT: The paper discusses the history of the Open-Air School of São Paulo, a preschool institution created in 1939 inside the Água Branca Park in the city of São Paulo, Brazil. Its classes were carried out with portables blackboards and school desks. International, national and local knowledge about open-air institutions that were in circulation in São Paulo in previous years was appropriated for its creation. The school was promoted as a model institution, being used as field of application and internships for students from the Higher School of Physical Education and the Normal School Caetano de Campos. In 1952 the school was transferred to a special building, which ensured the realization of open-air classes. The sources used in this research are newspaper articles from São Paulo’s press, decrees, laws, draft legislation, official reports, books, monographs and journals of education and physical education.

title: ARTICLE - GEORGES HÉBERT AND WOMEN’S PHYSICAL EDUCATION IN BRAZIL

description: ABSTRACT: In the book Muscle et beauté plastique (1909), dedicated to young French women, Georges Hébert established the concepts of health, beauty and strength oriented to women’s emancipation by means of his Natural Method. This book was read in Brazil by authors from the field of physical education such as Rangel Sobrinho (1930) and Lotte Kretzschmar (1932), who proposed national methods for “women’s physical education”. This article analyzes the principles of women’s education in Hébert’s work and discusses its reception in Brazil in the 1930s. The sources used comprise Rangel Sobrinho’s and Kretzschmar’s books, Brazilian publications of the period and Hébert’s book Muscle et beauté plastique. We were able to determine that this French work was innovative regarding women’s education for proposing physical and moral emancipation, opposing the wearing of corsets and high heels and advocating equal exercise for men and women. However, the Brazilian works presented limitations regarding women’s training, since the idea of equality was proposed but not actually applied to the training program.

title: ARTICLE - FROM THE GYMNASTICS CENTRAL INSTITUTE (GCI) IN STOCKHOLM TO BRAZIL: CULTIVATION AND SPREADING OF AN EDUCATION OF THE BODY

description: ABSTRACT: This paper presents the results of a research on the Stockholm Gymnastics Central Institute and how the Swedish Gymnastics method was disseminated and cultivated. It shows how the GCI, with its training policies and strategies of action, collaborated to disseminate gymnastics in several countries. It focuses on Brazil, mainly on the different ways by which the method gained visibility: in the pedagogical thinking, in school textbooks and in the presence of Fritjof Detthow, a professor who graduated from the Institute in São Paulo. The study shows that the lingian gymnastics that arrived in Brazil must be taken as a cultural object, as a practice that does not remain pure and that, in its circulation, carries a transformative dimension. The gymnastics that Detthow brought to Brazil has deep relations with the one learned in the Institute, although it became different when in contact with a new cultural and political scenario.
