Authors: Maciel Geraldo de Freitas , Toniati André Luis , Ferreira Fabiana de Oliveira
Published: October 2018

RESUMO Neste artigo foi proposto um modelo matemático simplificado para inferir sobre a capacidade erosiva de um escoamento lamoso em regime laminar com presença de roll waves (efeito pulsante) na superfície livre. Na perspectiva de aplicação de resultados no contexto de desastres naturais (corridas de lama), foi determinada a evolução da velocidade média e da tensão de cisalhamento no fundo do canal. O modelo proposto é baseado nas equações de águas rasas e na reologia de Herschel-Bulkley, como representativa das lamas. A validação e a aplicação do modelo foram feitas a partir de dados experimentais de roll waves geradas em canal no laboratório confrontados com resultados de simulações numéricas. Os resultados obtidos mostram um incremento na capacidade erosiva, na presença de roll waves, da ordem de 12% em relação ao escoamento base, valor este em concordância com os 10% apontados por Ng e Mei (1994) para uma reologia mais simplificada.

ABSTRACT The release of wastewater and the shrimp feed cost are the main challenges faced by the shrimp farming industry. An alternative solution to both problems is biofloc production in a unit external to the farm, in an activated sludge system for effluent treatment. The treatment system’s influent was composed of the shrimp farm wastewater supplemented with urea and sugarcane molasses. The results show that the average removal of chemical oxygen demand was 71% and the average biofloc production in the reactor was approximately 1.5g.L-1. Adding molasses to the influent contributed to the increase in the quantity and diversity of existing microorganisms that are beneficial to cultured shrimp. The mass balance of nitrogen compounds confirmed that nitrification occurred in the system. Therefore, the use of the activated sludge system is a viable and environmentally suitable alternative to produce bioflocs and shrimp farming effluent treatment.

ABSTRACT Objective: To identify the factors associated with family risk of children with special health care needs. Methods: Bicentric study, with a cross-sectional design and a quantitative approach, with family caregivers of children with special health care needs. Instruments were applied to obtain a sociodemographic characterization, and identify and classify the family risk. For analysis between variables, Mann-Whitney and Fisher’s exact tests were used and the Spearman’s correlation coefficient was calculated. Results: One hundred and eighteen caregivers participated in the study. The average family risk score was 3.53 (±3.76), with a median of 3.0, and minimum and maximum values of 0 and 16, respectively, with no significant difference between the two studied Brazilian municipalities. In municipality 1, the number of siblings presented a positive correlation with the average family risk score (0.011, p<0.05). Level of education and marital status of the caregiver showed a significant association with the result (0.038 and 0.002, respectively). The social classification variable presented a negative correlation with the outcome in municipalities 1 (0.003, p<0.01) and 2 (0.006, p<0.01). Conclusion: To classify the family risk and recognize associated factors can be taken as a basis for fair home care to children with special health care needs.

Published: October 2018

Abstract This work was conducted to evaluate the hardening phenomenon of pastes formulated with Portland cements blended with limestone filler (CPIIF), ground blast furnace slag (CPIIE) or pozzolan (CPIIZ). Vicat test, isothermal conduction calorimetry and oscillatory rheometry were the methods used to monitor this transition. The results of Vicat test indicates the faster setting time of pozzolan cement, but no information before this time was obtained. Using isothermal calorimetry was possible to monitor the related changes to the chemical reactions since the first contact with water, and using rheometry, the rate and force of cement particles agglomeration. The main purpose of this work was not extensively explain the results of these three methods, but show that they are complementary to better explain the transition from fluid-to-solid behavior in function of different kind of mineral addition.
Numerical and experimental assessment of a typical brazilian footbridge
Authors: DOZ G. N. , BRITO J. L. V. , BRASILIANO A.
Published: October 2018

Abstract For the range of medium spans, around 30 to 40m, composite footbridges are getting popular in Brazil. This kind of structure consists on longitudinal steel truss beams providing support for a concrete deck usually made of precast elements. Typical examples of these structures may be found in many cities in Brazil, especially in Brasilia where a large number of highways demanded a significant set of footbridges. Due to the amount of this kind of composite footbridges in Brazil, studies concerning their mechanical behavior are required in order to ensure pedestrian’s safety. For this end, in this paper, a typical Brazilian composite footbridge located in Brasilia is analyzed by means of experimental tests and computational modeling. The focus is the determination of natural frequencies and mode shapes. Strategies to correctly obtain the vertical modes are also discussed since vertical vibration is the main vibration problem expected for the tested footbridge. The obtained results showed that structural balance between stiffness and mass leads to natural frequencies out of the critical frequency range excited by pedestrians in normal use, although the idea was not to measure how these parameters, mass or stiffness, could influence the model. Moreover, Finite Element models were evaluated comparing complexity versus accuracy to predict modal parameters.
Experimental study on the interference intensity produced by the presence of neighboring buildings in the wind action in a tall building
Authors: VIEIRA G. S. , BRITO J. L. V. DE , LOREDO-SOUZA A. M.
Published: October 2018

Abstract The average strain on a building due to the action of the wind, can be significantly altered when considering the presence of one or more neighboring buildings. Such changes can be considered through the use of coefficients that take into account the distance that the neighboring building is from the building being studied. The present work was developed in order to verify the values currently adopted by the Brazilian standard that regulates the wind action in buildings. With the use of a wind tunnel, several tests were carried out in a standardized building considering the presence of other buildings with similar dimensions close to it. The distances between the buildings, the quantity and the layout of the neighboring buildings were taken into consideration. It was possible to conclude that, in general, the presence of the neighboring buildings produced an increase on the strain. Interference, in many situations, increased strain above the rates suggested by the current Brazilian wind action standard.
Analysis of the effects of soil-structure interaction in reinforced concrete wall buildings on shallow foundation
Authors: SANTOS M. G. C. , CORRÊA M. R. S.
Published: October 2018

Abstract This paper presents a study of the effects caused by soil-structure interaction in reinforced concrete wall building on shallow foundation. It was verified the influence of displacements of supports on the redistribution of internal forces in the structural walls and in the redistribution of loads on the foundation. The superstructure was represented by shell finite elements and the soil-structure interaction was evaluated by iterative methods that consider the stiffness of the building, the soil heterogeneity and the group effect of foundation elements. An alternative model that considers the soil-structure interaction is adopted and the concrete walls are simulated by bar elements. The results indicate that the soil-structure interaction produces significant changes of the stress flow, with larger influences on the lower walls, as well as a tendency of settlements standardization and load migration to supports with smaller settlements.

Abstract Steel fibers in reinforced concrete increase the performance of slab-column connection once they increase ductility and energy absorption capacity of the concrete. The use of fibers in flat slabs may increase strength and change the mode of failure. The objective of this work is to present an experimental evaluation of punching shear strength of reinforced concrete flat slab with steel fibers and punching shear reinforcement. Eight square slabs, size 1800 mm by 1800 mm by 130mm, were loaded until failure by punching shear around the column. The models were divided in two groups, depending on the type of the concrete used (with or without steel fibers). The steel fiber volume used in the slabs of second group was of 0.9%. Each group was composed of four slabs: one without shear reinforcement and three with shear reinforcement (studs) distributed radially around the column. The use of steel fibers increased the ultimate strength of all flat slabs. In one of the slabs, the association of steel fibers with shear reinforcement changed the failure surface from outside to inside the punching shear reinforcement region.

Published: October 2018

Abstract Pervious concrete may be used for stormwater management since it allows the water to pass through its interconnected macropores into stormwater systems or soils below. However, there is a need for additional standards related to pervious concrete prior to its widespread use, and there are many aspects related to mix design for desired properties, compaction methods, and test procedures that are not yet completely understood. These variables may significantly affect the functional and mechanical performance of the material. In this paper, mix designs and test specimen preparation techniques were evaluated. The IBRACON method for mixture design was used to obtain the mixture proportions and the calculated density for the desired porosity of 25%. In addition, two different types of specimens (cast or cored) and compaction methods (roller or Proctor hammer compacted) were performed. The density of each specimen was controlled to obtain the same calculated density. Several tests were conducted to compare the following variables: density, porosity, surface infiltration rate, permeability and compressive strength. Additionally, the effects of mortar capping versus neoprene-rubber caps on compressive strength measurements of pervious concrete were evaluated. The experimental results showed that cast specimens have more consistent results than cores. The design method studied with strict control of density was efficient to obtain the desired porosity mainly for cast specimens. The roller leads to a more compacted top surface resulting in a decrease in the infiltration rate and permeability of the cores. The mortar capping method is more consistent than the other.
¡Madres negras tenían que ser! Maternidad, emancipación y trabajo en tiempos de cambios y transformaciones (Buenos Aires, 1800-1830)
Authors: Guzmán Florencia
Published: October 2018

Resumen: Durante las primeras décadas del siglo XIX, una combinación de mutaciones y transformaciones trajo derivaciones en la vida de los varones y las mujeres afrodescendientes de manera diferenciada. En este artículo me propongo considerar el desenvolvimiento de las mujeres madres negras y el modo en el que se verificó la relación con dos procesos novedosos y significativos de este periodo. Hago referencia a la gradual abolición de la esclavitud y a la transición del trabajo esclavizado al trabajo libre. Con esta finalidad he distinguido dos núcleos de análisis principales, que refieren tanto a la Ley de Libertad de Vientres, por un lado, como a las amas de leche negras y el servicio de amamantar, por el otro. Este trazado me da la posibilidad de explorar la manera en que se entretejen las maternidades, esclavitudes y emancipaciones de las mujeres negras en el ámbito urbano de la ciudad de Buenos Aires, como también sobre el modo en que se vincula y entremezcla lo femenino/ género con lo racial.
Representaciones sobre el acceso legítimo a bienes agro-ganaderos: tensión y judicialización en época de concentración. Zona centro-sur de Chile, 1824-1875
Authors: Brangier Víctor , Timmermann Freddy
Published: October 2018

Resumen: El artículo aborda las representaciones sobre el acceso legítimo a bienes agro-ganaderos, que evidenciaron actores sociales medios y medio bajo en una zona rural de Chile entre 1824 y 1875. Entonces, la zona centro sur experimentó la expansión de la gran hacienda triguera y la consiguiente indisponibilidad social de la tierra, del ganado y de sus derivados. El estudio aspira a visualizar el contenido y la tensión de este campo representacional y el papel que jugó la “proximidad” entre los sujetos, en esta coyuntura económica crítica. Desde la rama culturalista de la historia de la justicia, se analizan expedientes judiciales por hurto y robo de este tipo de recursos. Como resultado, se evidenciaron nociones compartidas y tensadas en torno al acceso legítimo a bienes agro-ganaderos, primando valores como la necesidad y la costumbre, al igual o más que conceptos como la eficiencia económica o la inviolabilidad de la propiedad.

Neste artigo, descortinarei de forma mais detalhada a relação bilateral entre Brasil e Estados Unidos ao longo daquele ano, bem como demonstrarei como a posição da Política Externa Independente do governo Goulart em relação a Cuba ao longo do ano foi a causa principal do afastamento entre os países e a razão da política de desestabilização patrocinada pelos estadunidenses. Para tanto, nossos interlocutores serão a documentação oficial produzida pelo Ministério das Relações Exteriores do Brasil, os pronunciamentos do presidente brasileiro, a grande imprensa, as cartas trocadas entre os presidentes Goulart e Kennedy e os documentos produzidos pelo governo dos Estados Unidos.
Names and Social Contracts: Late Gaelic Ireland and Celtic Studies
Authors: O’Neill Eoin
Published: October 2018

Abstract: Sixteenth century Gaelic Ireland is not normally associated with Celtic Studies. The aim of this paper is to show that not only can it be included, but it can also produce many useful insights for Celtic Studies. Using as an illustration a minor skirmish which occurred during the Nine Years War in Ireland, this paper will show how what at first may seem straightforward questions can be problematised, while also shedding a light on identity in sixteenth-century Ireland. Finally, the question of Gaelic contractualism is examined. This concept was quite widespread in Europe during the Renaissance and the later Medieval period, and in the works of sixteenth-century Spanish writers, notably Vitoria and Suárez, it gained a sophistication and radicalism not found in Hobbes or Locke. In Gaelic contractualism, the contract was not something rhetorical, or established in a distant past, rather it was dynamic, and allowed for a change of allegiance.

Aim.To analyze influence of perioperative intra-arterial selective chemotherapy on terms of recurrent ductal adenocarcinoma of pancreatic head after pancreaticoduodenectomy.

Material and methods. 111 patients underwent combined treatment. Surgical stage included conventional pylorussparing pancreaticoduodenectomy in all groups. The main group consisted of 52 patients who received combined treatment: neoadjuvant chemoembolization with gemcitabine (400 mg/m2) and oxaliplatin (50 mg/m2), surgical treatment and 6 courses of regional chemotherapy – infusion of gemcitabine (800 mg/m2) and oxaliplatin (45 mg/m2) into celiac trunk in adjuvant mode. The control group was presented by 59 patients who underwent perioperative regional chemotherapy (neoadjuvant chemoembolization and adjuvant infusion of gemcitabine (800 mg/m2). Progression-free survival (PFS) and terms of recurrence were analyzed in all groups. In case of progression and recurrence we applied regional chemotherapy alone. Systemic chemotherapy was not used in the study.

Results.Annual PFS in the main and the control groups was 80%. Three-year PFS in the main group was 37%, in the control group – 14% (p < 0.01). Five-year PFS was 11% in the main group and absent in the control group. Median survival was 26 months in the main group and 22.6 months in the control group. Overall annual, 2-year and 5-year survival in main group was 80%, 57% and 15%, respectively.

Conclusion.Regional intra-arterial chemotherapy decreases incidence of recurrences and improves PFS after surgical treatment of pancreatic head adenocarcinoma.Further multi-center studies are necessary to assess the effectiveness of regional chemotherapy.

Aim. To evaluate an effectiveness of non-invasive stimulation of gastrointestinal peristaltic activity in complex correction of motor-evacuation disorders and intra-abdominal hypertension in patients with severe acute pancreatitis.

Material and methods. There were 85 patients with severe acute pancreatitis. Patients were divided into two groups: group 1 (n = 43) – percutaneous resonance stimulation; group 2 (n = 42) – routine treatment of acute pancreatitis with intraperitoneal hypertension syndrome and dynamic intestinal obstruction according to normative documents. Intra-abdominal pressure was measured in 1, 3, 5, 7 days after disease onset. Abdominal perfusion pressure and filtration gradient were additionally calculated. Moreover, outcomes were assessed after 1, 3, 5, and 7 days according to visual-analogue scale.

Results. There were faster regression of intraperitoneal hypertension followed by normalization of abdominal pressure after 7 days in group 1 compared with group 2 (p ≤ 0.05). Data of visual-analogue scale confirmed patients’ good tolerability of resonance stimulation including absent local discomfort during electrodes deployment and better state of health compared with group 2 (p ≤ 0.05). Infectious complications rate was 20.9% in group 1, 38.1% – in group 2. Sepsis developed in 3 (7%) patients of group 1 and in 7 (16.6%) patients of group 2. Overall mortality was 7% and 14.3% in both groups, respectively.

Сonclusion. Percutaneous resonance stimulation is able to improve outcomes in patients with severe acute pancreatitis.
Temporary endobiliary stenting of distal strictures of the common bile duct due to chronic pancreatitis
Authors: Okhotnikov O. I. , Yakovleva M. V. , Grigoriev S. N.
Published: October 2018

Aim.To determine the possibility, necessity and safety of self-expanding covered endobiliary stents in benign biliary strictures caused by chronic pancreatitis.Material and methods.Nine patients with painless chronic pancreatitis complicated by obstructive jaundice syndrome were enrolled. Minimally invasive treatment included stage-by-stage percutaneous transhepatic cholangiostomy by pigtail 8Fr drain followed by its transformation to temporary transpapillary external-internal drainage. Then we performed antegrade endobiliary stenting of stricture with self-expanding metal stent 9 mm. There were no symptoms of acute pancreatitis. External-internal drainage in within bile duct lumen has been kept for 2–4 weeks to control position and patency of the stent.

Results.Technical success of antegrade deployment of self-expanding covered stent into transpapillary position was achieved in all patients. The time of complete opening of the stent was 2 days. Ultrasonic control every 2 months was applied since stent has been installed. All 9 stents were successfully and uneventfully extracted endoscopically after 6–12 months. There were no cases of recurrent mechanical jaundice. Mean disease-free follow-up was 22.8 months.

Conclusion.Covered stent opening followed by stricture dilation up to 8-10 mm within distal common bile duct confidently eliminates biliary hypertension. Stenting of this area is followed by formation of stable periductal carcass within 6–9 months which is preserved even after endoscopic extraction of the stent. Minimally invasive management of biliary hypertension using covered self-expanding metal stent in transpapillary position may be an alternative to traditional surgery in selected patients with chronic pancreatitis and mechanical jaundice as predominant clinical syndrome.

Aim. To analyze complications of percutaneous transhepatic cholangiostomy depending on biliary obstruction level and drainage type.

Material and methods. Percutaneous transhepatic biliary drainage was carried out in 974 patients with mechanical jaundice of different genesis. External drainage was predominantly performed for distal obstruction, external-internal suprapapillary – for proximal obstruction. Strictures of biliodigestive anastomosis were managed using percutaneous balloon dilatation and long-term external-internal drainage.

Results. Overall morbility was 19.1%. Significant relationship between morbidity and obstruction level, drainage type and tubes quantity was detected. Drainage tube dislocation was the most common drainage-related complication both in proximal and distal obstruction. External-internal transpapillary drainage was followed by suppurative cholangitis and acute pancreatitis in 81.5% of cases. External-internal suprapapillary drainage was accompanied by acute cholangitis in 17.1% of patients and was determined by disconnection of subsegmental ducts that required additional drainage tubes placement. In most cases, complications were corrected by minimally invasive surgery and nonsurgical treatment. Overall mortality was 1.3% (0.3% in cases of distal obstruction and 1.8% in cases of proximal obstruction).

Conclusion. Percutaneous transhepatic biliary drainage is a routine non-traumatic method of biliary decompression that may be successfully used irrespective to obstruction level and cause of jaundice. External-internal suprapapillary drainage is preferable for proximal biliary obstruction while external-internal transpapillary drainage should be avoided.

Published: October 2018

INTRODUÇÃO: A taxa de doações de órgãos e tecidos vem crescendo durante os anos. Porém, a não efetivação das doações ainda é alta, sendo o principal fator a recusa familiar. OBJETIVO: Descrever os motivos de recusa familiar para doação de órgãos e tecidos. MÉTODOS: Estudo quantitativo, descritivo, retrospectivo, transversal e exploratório, realizado com 350 prontuários de pacientes potenciais doadores de órgãos nos hospitais de Petrolina-PE, entre os anos de 2013 a 2017. Para coleta de dados utilizou-se um formulário de pesquisa elaborado pelas autoras. Os dados foram tabulados e armazenados no programa Excel for Windows/2013, compondo o banco de dados da pesquisa. Projeto aprovado pelo Comitê de Ética em Pesquisa da Universidade do Estado da Bahia sob nº 65496017.3.0000.0057. RESULTADOS: Foram analisados 350 prontuários de potenciais doadores os quais a entrevista familiar foi realizada. Para este estudo, foram utilizados apenas os prontuários em que houve a recusa familiar para a doação dos órgãos e tecidos, totalizando 147. As causas mais frequentes foram: corpo íntegro (36,0%), desconfiança do processo de doação (32,6%), doador contrário em vida (16,3%), revolta com atendimento da equipe hospitalar (4,7%), demora do processo de doação (2,7%), motivos religiosos e não compreensão da morte encefálica (1,3%). CONCLUSÃO: Percebe-se que os fatores de recusa remetem à falta de informação e divulgação sobre o processo de doação, sendo necessário que campanhas educativas sejam realizadas com o objetivo de esclarecer a população sobre esta temática, visando diminuir as negativas devido à recusa familiar.

Published: October 2018

The article presents the results of the study of the University professor’s readiness to work with students with disabilities. The readiness of the University professors to work in the system of inclusive education considered by the authors as a complex integrative professional and personal formation. It consists of three interrelated components: cognitive, affective and behavioral. Behavioral is one of the conditions for the success of teaching students with disabilities in high school. In other words, the effective professional activity of a University professor is facilitated by the knowledge of the students’ personality and their health features, positive attitude, acceptance and experience of interaction with them. In the framework of the study, 119 university professors of Russia, Belarus and Poland surveyed. The results allowed to determine the degree of readiness of University professors to work with students with disabilities and, as a result, demonstrated the need for developmental correction of each of the three components of this readiness.
Understanding of Emotional States in Persons with Pedophilia / Pedophilic Disorder
Authors: Demidova L.Y. , Dvoryanchikov N.V.
Published: October 2018

This article highlights the problem of emotional perception in pedophilia (ICD-10) / pedophilia disorder (ICD-11). In present paper, emotional perception is considered as abilities of recognizing and identifying a wide range of mental states like emotions, affects, moods, feelings. The assumption about relations of alexithymia and disturbances in the recognition of emotions, perspective taking, empathy with pedophilia and regulatory mechanisms of activity verified empirically. Two groups of persons accused of sexual crimes are compared: 44 people with pedophilia, 32 people without the disorder; also 95 persons who haven't been accused were examined for the control group; as well intra-group comparison of pedophilic persons with egosyntonic and egodystonic attitude toward sexual drive was made. Contradictions of earlier studies are resolved in the result: it is shown that in pedophilia the ability of understanding emotional states remains normal at first sight (in comparison with the deficits found in the accused without pedophilia). However, the group with pedophilia is characterized by extremely high level of alexithymia and based on this the consistently conclusion is made about disturbances of emotional regulation in egosyntonic form of this disorder.

Published: October 2018

The aim of present research was to investigate the performance of visual perceptual tasks with varying the degree of uncertainty and levels of regulation prescribed by vague, verbal and non-verbal instructions. The modified Witkin test and Wechsler Adult Intelligence Scale, a revised form (WAIS-R) were used. 36 anankastic personality disorder patients (mean age-31,9±9,8 years), 38 schizophrenic patients (pseudoneurotic type, mean age 30,8±8,7 years) and 100 healthy controls (mean age 27,5±8,5 years) were enrolled to the study. It was established that the effectiveness of the performance of visual perceptive tasks in conditions of vague instruction did not differ among the subjects of all three groups. The introduction of additional verbal instruction increased the performance of healthy subjects and patients with anankastic personality disorder, in contrast to patients with schizophrenia. In conditions of nonverbal instruction, the effectiveness of performing was reduced in clinical and control groups, but the parameters of healthy subjects were significantly higher (р≤0,05). It was found in schizophrenia an increase in the number and strength of the correlation between the indices of the performance of visual perceptual tasks and the non-verbal parameters of Wechsler Adult Intelligence Scale.

Published: October 2018

This paper describes the upgrade of Atlas tracking radar system transmitter at Alcantara Launch Center (CLA), Maranhão, Brazil. The original transmitter installed in the 1980’s was equipped with a conventional hard-tube pulse modulator to excite a 1MW C-band magnetron. In order to extend overall system lifetime, improve reliability and introduce new monitoring and command functions the original tubetype modulator and control system was substituted by a modular line-type solid-state modulator and a digital control system.

Published: October 2018

Este artigo relata os resultados de uma parceria de sucesso entre Universidade e Empresa que conduziu ao desenvolvimento de um novo produto industrial. O principal estímulo para esta parceria foi a total carência de estudos científicos no segmento de energizadores de cerca elétrica, comprovada através de uma ampla revisão bibliográfica, que vinha obrigando os fabricantes a desenvolver seus produtos através de métodos empíricos os quais implicavam na implementação de diversos protótipos intermediários resultando em longo tempo de projeto e, conseqüentemente, em elevado custo. Para superar estas dificuldades, foi desenvolvido, no escopo desta parceria, um completo estudo que permite a análise e a síntese deste tipo de equipamento, culminando na qualificação de recursos humanos e no desenvolvimento de tecnologia própria. Este trabalho está fundamentado nas teorias de eletrônica de potência, linhas de transmissão, aterramento e compatibilidade eletromagnética e atende às normas internacionais de segurança elétrica (IEC).

Published: October 2018

Uma nova topologia para reatores eletrônicos para Lâmpadas de Vapor de Sódio de Alta Pressão (HPS) com Alto Fator de Potência (HPF) será apresentada neste trabalho. Sem a necessidade de usar um estágio de Correção de Fator de Potência (PFC), um conversor direto de freqüência, CA-CA, é capaz de obter HPF e suprir corrente em alta freqüência para a lâmpada. Devido a esta característica a corrente na saída apresenta-se modulada na freqüência da tensão de entrada; esta característica é apresentada e discutida. Em seguida, diferentes topologias, interruptores bidirecionais e estratégias de modulação para o conversor CA-CA são apresentados. Finalmente, resultados experimentais de um protótipo para uma lâmpada HPS de 250W serão analisados.

Published: October 2018

Este artigo apresenta uma metodologia de simulação com o programa MATLAB/Simulink aplicada a projetos de reatores eletrônicos dimerizáveis que alimentam lâmpadas fluorescentes. No trabalho são descritas as etapas para o emprego do simulador e as possibilidades de simulação, assim como as vantagens e desvantagens de utilizar esta ferramenta para projeto. A metodologia é ilustrada através de uma abordagem hierárquica para simulação de um reator eletrônico dimerizável realimentado através da corrente da lâmpada fluorescente. Inicialmente, conforme a metodologia proposta, utiliza-se na simulação um modelo simplificado do reator, enquanto que na etapa seguinte é empregado um modelo mais detalhado. Um protótipo foi implementado para avaliar a metodologia apresentada através da comparação dos resultados experimentais e de simulação.
Magnetically-coupled Current Sensor Using An Integrated Coil And A Cmos Split-drain Transistor
Authors: Castaldo Fernando C. , Dos Reis Filho Carlos A.
Published: October 2018

An integrated current sensing circuit intended for Smart-Power and embedded applications featuring galvanic isolation is implemented. It is based on magnetic detection using the CMOS compatible Split- Drain transistor (MAGFET) that provides a very linear output current versus magnetic field. The current to be sensed flows through an integrated coil placed atop the split-drain transistor and produces a relatively strong magnetic coupling enough to cause a detectable transistor unbalance current. An integrated sensor built in 0.35ìm CMOS technology presented an output conversion factor of 1500nA/A and a minimum detectable magnetic field around 1ìT within 1Hz bandwidth in thermal range for 100ìA transistor bias current.
Posterior Interosseous Neuropathy in the Distal Radial Tunnel in a Contrabassoon Musician
Authors: Jepsen Jørgen R
Published: October 2018

OBJECTIVE: Bassoonists seem to have a high recorded prevalence of performance-related upper limb symptoms. Yet, the background for their symptoms has not been established. This study aimed to diagnose and treat the pathology that caused severe upper limb symptoms in a bassoon/contrabassoon
musician in order to allow him to continue his professional career in a symphony orchestra. METHODS: A detailed neurological bedside examination was undertaken and targeted physiotherapy offered. RESULTS: The physical examination demonstrated weakness, atrophy, and nerve trunk soreness, indicating
an affliction of the posterior interosseous nerve (radial tunnel syndrome) or its muscular branches. The risk factors during bassoon playing are comparable to those reported from industrial exposures. The patient was able to resume playing after treatment by nerve mobilisation.

Published: October 2018

OBJECTIVE: Reducing work-related health hazards at the different theatre workplaces is one aspect of preventive options in professional dance. This also applies to hazards on the highly variable theatrical stage areas. However, detailed information on these stages and their risks is
not available. The aim of this study was to analyze and evaluate work-related traumatic injuries in the stage area. METHODS: The basis for the evaluation was accident reports, from the German National Statutory Insurance, of work-related traumatic injuries occurring on stage in professional
dancers (n=790: 407 males, 383 females) over a 17-year period (1995-2011). RESULTS: Most (79.4%) of the accidents on stage occurred during an ongoing performance (frequency: 10.1/100 performances), with only 19.7% occurring during rehearsals on stage (p<0.001). Due to the sustained injury,
30.2% of the dancers sustained a time-loss injury. Most (57.7%) of the injured dancers were older than 25 years. Of the accidents, 59.3% were initiated by a definably extrinsic cause, with 40.7% caused by intrinsic factors (p<0.001). Injuries were most commonly caused by the “partner”
(21.7%) or “floor” (21.0%). The lower extremity was the most commonly affected body region (63.6%) (p<0.001). CONCLUSION: Stage performances seem to carry an increased injury risk compared to rehearsals. The “risk” of on-stage work is spread across various factors
that seem to be stage-specific. There is a need for further qualitative and quantitative research to be able to classify the stage as workplace more precisely.
Prevalence, Risk Factors, and Effects of Performance-Related Medical Disorders (PRMD) among Tertiary-trained Jazz Pianists in Australia and the United States
Authors: Wood Graham C
Published: October 2018

This study explores performance-related medical disorders (PRMD) among a sample of tertiary-trained jazz pianists. Participants included both Australian and US pianists (n=214), including current and former tertiary students, professional pianists, and teachers. This mixed methods (quantitative
and qualitative) exploratory and descriptive study used survey and case studies to provide baseline data for further research. Students reported a past and present period prevalence of 63% for pain and 41% for PRMD (injury attributed to practice or performance) with the forearm being the body
part most affected, usually by fatigue. Diagnosis and treatment were reported as often unsatisfactory mainly due to lack of knowledge of PRMD by teachers and by professional health providers, and also to limited access to specialist PRMD services where these exist. Although teacher knowledge
of PRMD is quite low, students still seek advice primarily from their teachers. The current study highlights a need to address the issue of PRMD among jazz pianists and their teachers more strategically, both in its prevention and in diagnosis and treatment.

Published: October 2018

OBJECTIVE: To assess the prevalence and intensity of musculoskeletal pain and to estimate probability of developing playing-related musculoskeletal disorders, depending on risk factors, including gender, years of playing the musical instrument, frequency of practice (number of days
per week), average daily practice time, and habitual physical activity level, in young instrumentalists. METHODS: A total of 225 instrumentalists aged 10–18 years, including 107 string-players, 64 keyboardists, and 54 wind-players, were investigated. The Nordic Musculoskeletal Questionnaire
(NMQ) together with a numerical visual-analogue pain intensity scale (VAS) was used to assess the participants’ musculoskeletal pain. RESULTS: The young instrumentalists most often complained of pain located in the neck (60.4%), wrists (44.4%), and upper (41.7%) and lower back (38.2%)
areas. Girls complained of musculoskeletal pain significantly more often than the boys. A probability of the pain symptoms was increased with each consecutive year of practice (OR 1.135; 95%CI 1.021–1.261). CONCLUSIONS: Musculoskeletal pain in various body parts had already commenced
at a young age in our sample of music students, and there was a gender difference (girls were more often affected). Results of our study suggest that an early prophylaxis of playing-related musculoskeletal disorders is needed among young musicians playing the various instruments.
Knee Injury Patterns in Young Irish Dancers

Published: October 2018

OBJECTIVE: To characterize knee injury patterns in Irish dancers. METHODS: A retrospective chart review was performed for Irish dancers under age 19 who presented with knee injuries to the sports medicine or orthopedic clinic from January 1, 2000 to December 31, 2010. Data were collected
on all knee injuries partially or directly related to Irish dance. Injury was defined as dance-related pain or damage to the structures in the knee that resulted in evaluation in the clinic. Survey data were collected to determine the number of different schools/studios represented by the
dancers in the study. RESULTS: Sixty-seven Irish dancers with 86 knee injuries were evaluated. Half (50.7%) of these patients received more than one diagnosis during these visits. Overuse injuries accounted for 90.7% of knee injuries. Time to presentation ranged from less than 1 week to over
1 year. There was a significant difference in time to presentation, with traumatic injuries being evaluated sooner than overuse injuries. The most common diagnoses, accounting for 53.5% of injuries, were patellar tracking disorders, including patellofemoral syndrome, hypermobile patella, and
patellar subluxation. CONCLUSION: In Irish dance overuse injuries represent the great majority of knee injuries, and patellofemoral tracking disorders are the most common diagnosis. For many dancers, there is often a delay of weeks to months between the onset of symptoms and evaluation in
clinic. Prevention programs could potentially eliminate a large portion of knee pain experienced by young Irish dancers.
