Published: April 2015

Os programas de melhoramento devem ser dinâmicos e contínuos, de modo a disponibilizarem sempre novos cultivares de cafeeiros, com fatores de resistência complexos, que se constituam em eficientes barreiras para as novas raças fisiológicas do fungo H. vastatrix. Por essa razão, objetivou-se, com este trabalho, avaliar o comportamento agronômico, a resistência à ferrugem e a ocorrência de cercosporiose em progênies, provenientes do cruzamento dos grupos de cultivares Catuaí e Icatu, em dois ambientes de Minas Gerais. Os experimentos foram implantados nas Fazendas Experimentais da EPAMIG, em São Sebastião do Paraíso e Três Pontas - MG. O delineamento experimental adotado foi o látice quadrado 6 x 6, com 3 repetições. Nos dois ambientes, foram realizadas avaliações de produtividade, vigor vegetativo, percentagem de grãos com peneira 17 acima e reação à ferrugem e à cercosporiose, nos anos agrícolas 2009/2010 e 2010/2011. O desempenho das progênies avaliadas, para produtividade, em Três Pontas, foi superior quando comparado ao de São Sebastião do Paraíso. A progênie H 6-47-10 Cova 3 destacou-se entre as mais promissoras, sugerindo boas possibilidades de progresso genético na seleção.

O objetivo deste trabalho foi verificar o desempenho de clones elite de batata, em relação a caracteres agronômicos e de qualidade industrial. Os experimentos foram realizados em Pelotas, RS, Canoinhas, SC, e Londrina, PR. Foi avaliado um conjunto de clones elite, pertencentes ao Programa de Melhoramento Genético de Batata, da Embrapa. O delineamento experimental foi o de blocos casualizados, com três repetições para Pelotas e Londrina e quatro para Canoinhas. Foram avaliados os caracteres massa total de tubérculos, massa comercial de tubérculos, número de tubérculos comerciais, percentagem de massa de tubérculos comerciais, massa média de tubérculos comerciais, peso específico, cor de fritura e ciclo vegetativo. A partir dos dados obtidos foram realizadas as análises de variância para cada local e teste de agrupamento de médias para cada caráter. Para identificação de clones apropriados ao mercado 'in natura', em que é fundamental o elevado potencial produtivo e precocidade, os clones mais promissores foram F80-03-06 e CL02-05, quando comparados à cultivar testemunha Ágata. Para o processamento industrial, em que o peso específico, a cor de fritura e o rendimento de tubérculo são caracteres importantes, destacou-se o clone F81-01-06, que apesar de não apresentar os maiores rendimentos totais, apresentou tubérculos grandes, ciclo vegetativo intermediário e boa aptidão para fritura, quando comparando-se ao cultivar testemunha Asterix.

Fruteiras como Eugenia involucrata ainda continuam inexploradas, necessitando-se de informações técnicas que incentivem o agricultor a utilizá-las. O método de propagação por sementes é o normalmente adotado; porém, elas devem ser imediatamente semeadas, pois corre-se o risco de perda de sua viabilidade com o armazenamento. O objetivo deste trabalho foi avaliar o hidrocondicionamento e as técnicas de conservação (vácuo e biofilme), durante armazenamento, aos cinco e aos 30 dias, de sementes de cerejeira-do-mato. O trabalho foi realizado na Universidade Tecnológica Federal do Paraná - Câmpus Dois Vizinhos. O delineamento experimental foi em blocos ao acaso, em fatorial 2 × 4 × 2 (pré-hidrocondicionamento x técnica de armazenamento x tempo de armazenamento), com quatro repetições, de 50 sementes por unidade experimental. As sementes extraídas foram separadas em dois lotes, sendo um submetido ao pré-hidrocondicionamento, em água destilada, durante 24 horas, e, outro, não. Sementes hidrocondicionadas, ou não, foram submetidas a quatro técnicas de armazenamento, sendo, estas, a embalagem plástica a vácuo, o revestimento com biofilme de fécula de mandioca (3% m/v), a embalagem plástica a vácuo + biofilme de fécula de mandioca e sem tratamento (controle). Posteriormente, as sementes foram mantidas em câmara fria, em temperatura de 5 ºC e UR 85%, durante cinco e 30 dias. Aos 110 dias após a semeadura, avaliou-se a percentagem de germinação, o índice de velocidade de emergência e a massa da matéria seca total das plântulas. Para o armazenamento das sementes de cerejeira-do-mato, devem-se utilizar técnicas a vácuo, isoladamente, ou com revestimento de biofilme.

Objective The aims of this study were to evaluate the reliability of three range of motion tests (Straight Leg Raise, Modified Thomas, and Duncan-Ely) using photographic measurements in children with spastic diplegic cerebral palsy (SD) and with typical development (TD). Methods A cross-sectional test-retest design was applied to compare muscle-tendon unit shortening tests between groups. Results The tests showed reliability that ranged from good to excellent (ICC > 0.8), except for the Thomas Test for the bi-articular hip flexor muscle-tendon unit of the TD group (ICC = 0.7). Differences between groups were found in all tests (p < 0.05), except when the range of motion of the bi-articular hip flexor muscles was assessed using the Thomas test (p > 0.05). Conclusion Children with SD presents a smaller range of motion than the TD group. However, the Thomas Test for the bi-articular hip flexor muscles was unable to determine differences between children with spastic diplegic cerebral palsy from that with typical development.

Introduction Cryotherapy is often used for rehabilitation of injured athletes. Objective To compare the effectiveness of ice pack (IP) and cold water immersion (CWI) on lowering the ankle skin surface temperature in athletes. Materials and methods Thirteen athletes (seven women and six men), age 19.53 (± 2.9) years. IP and CWI were applied on the anterior talofibular ligament (ATFL) of the dominant leg for 30 minutes. The skin surface temperature was measured with an infrared digital thermometer prior to the application and during cryotherapy (10, 15, 20, 25 and 30 minutes) and up to two hours of rewarming. During rewarming, the athletes remained at rest and the temperature was measured every 1 minute until 10 minutes, every 5 minutes for up to an hour and every 15 minutes until 2 hours. Results The two types of cold application were effective in lowering the skin surface temperature after the 30-minute procedure. Significant differences were observed among the following temperatures: pre-application (IP = 29.8 ± 2.4 °C and CWI = 27.5 ± 3 °C – P < 0.05); after 30 minutes (IP = 5 ± 2.4 °C and CWI = 7.8 ± 3 °C – P < 0.01). For rewarming, after 25 minutes (IP = 20.8 ± 3.3 °C and CWI = 18.2 ± 2.7 °C – P < 0.04); after 45 minutes (IP = 24.5 ± 2.3 °C and IP = 22.1 ± 3.5 °C – P < 0.05); after 75 minutes (IP = 26.4 ± 2.2 °C and CWI = 24 ± 2.7 °C – P < 0.02). Conclusion After the 30-minute application, both IP and CWI produced the appropriate temperature; however the application of CWI produced the lowest temperature during rewarming.

Introduction In the Family Health Strategy (FHS), the treatment of Diabetes Mellitus (DM) includes education and lifestyle change strategies. Physiotherapists have a key role in this health setting. Objectives To implement actions of evaluation and guidelines for patients with type 2 DM who attend a Family Health Strategy (FHS), regarding diabetic foot and the practice of regular physical exercise in the control and prevention of the complications of Diabetes Mellitus. Methods 17 individuals from an FHS were evaluated, with the following procedures: clinical and anthropometric parameters, inspection, a questionnaire on diabetic neuropathy, tests of vibratory and tactile sensitivity, muscle function, range of motion, functional analysis, questions about exercise practice and guidance regarding controlling blood glucose and foot care. Results Deformities, dry skin, calluses, dehydration, ulceration, cracking and brittle nails were found. Peripheral neuropathy was not observed; tactile sensitivity was altered in the heel region and the vibratory sense was absent in 5% of individuals. A decrease in functionality of ankle movements was verified. Of the participants, 76% were sedentary, 24% knew about the benefits of practicing regular exercise, 25% had undergone a medical evaluation prior to performing physical exercise and, of these, 25% were supervised by a qualified professional. Discussion The implementation of physiotherapy actions in diabetics from an FHS was important for highlighting the presence of risk factors for diabetic complications. Conclusions Individuals attending the FHS need more information and programs for the prevention of diabetic complications.

Published: April 2015

Introduction Spinal cord injury (SCI) results in motor, sensory and autonomic dysfunction. The symptoms observed in patients with spinal cord injury will depend on the area affected by the injury. Nursing care is essential for better patient outcomes. Objective The aim of this study was to characterize patients with spinal cord injury treated at a state referral rehabilitation center for SCI. Methods We performed a quantitative cross-sectional descriptive study of 109 patients between the years 2000 and 2009. Results We found a predominance of spinal cord injury in men aged up to 30 years (48.5%). The main causes of spinal cord injuries were traffic accidents. The thoracic region was the most frequently affected site (39.7%), followed by the cervical region (25.6%). Most of the study subjects had been rated as ASIA A, according to the American Spinal Cord Injury Association scale. Discussion These findings corroborate previous studies observing that traffic accidents are the leading causes of spinal cord injury and that people affected by it usually do not seek proper care. Receiving early intervention services and counseling is essential for a better outcome and for achieving an improvement in the quality of life of these patients. Conclusion Despite the increasing incidence of spinal cord injuries nowadays, there is still a lack of data on the subject. The greatest limitation of this study is the incompleteness of medical records, which hindered the access to information.

Published: April 2015

Introduction Studies recommend a participation by preterm children (PT) in Early Intervention Programs (EIP), as the coordination dysfunctions appear to occur more frequently in premature school children. Objectives Describe the global motor coordination (MC) in PT children that participate in an EIP; verify the difference in MC between the sexes and correlate the coordination results of PT children and those with gestation age (GA) and the birth weight (BW); and compare the results of MC between PT children and full-term children (FT). Materials and methods 57 children (5-6 years old) – 20 PT that participate in EIP, and 37 FT. For the analysis of MC, it was used the Körperkoordination für Kinder (KTK) – Test of Body Coordination for Children. To the comparisons, it was used independent-samples T-test and the Mann-Whitney test (α = 0.05), and the Pearson correlation to verify the influence of GA and BW in the coordinated results. Results 80% of the PT children presented normal MC; the girls demonstrated a better performance on the tasks balance beam and lateral jumps and with regard to the MC corresponding to the sum of the gross scores on the tasks; the GA and BW did not influence MC; and, there was no difference between MC in PT and FT children. Conclusion The PT children presented, in their majority, satisfactory levels of MC, and the girls presented better results. In addition, the GA and BW did not interfere in the MC results. Lastly, there was no difference in the coordination performance between PT and FT children.

Published: April 2015

Introduction The urinary incontinence (UI) is a common pathology among women. In the gestation period, it is even more predominant, affecting between 20% and 67%. Objective To evaluate the relation between modes of delivery and parity on the occurrence of urinary incontinence during pregnancy. Methodology 80 pregnant and postpartum women, treated at the Hospital da Mulher, in Campo Grande, MS, Brazil, were selected during September and October 2011, following the inclusion and exclusion criteria of the research. The evaluation protocol consisted of a questionnaire on the clinical history of the patients, gynecological complications, urogynecologic and obstetric information. Results For independent samples, the comparison between the main values observed for the UI was given by the Mann-Whitney test and correlations between urinary incontinence and other variables were given by the Spearman's rank correlation coefficient. The studied group consisted of 40 (50%) primiparous and 40 (50%) multiparous women. The correlation between the following variables was not significant: parity and UI (r = 0.04, p = 0.7); parity and SUI (r = -0.81, p = 0.5); and parity and urge incontinence (r = 0.14, p = 0.19). In addition, the correlation obtained between vaginal delivery and the presence of urinary incontinence in primiparous (r = 0.08, p = 0.61) and in multiparous (r = -0.05, p = 0.76) was also not significant. The same occurs when cesarean delivery is correlated to urinary incontinence in primiparous (r = -0.08, p = 0.61) and multiparous women (r = -0.10, p = 0.5). Conclusion Parity and mode of delivery were not significantly associated with the occurrence of urinary incontinence during pregnancy.

Published: April 2015

Introduction University extension can be a vehicle for social change and aid in the education of university students; however, it is important to study how it is inserted in university programs so that educational actions and policies can be planned more adequately. Objectives To study the insertion of extension activities in undergraduate physical therapy curricula in Brazilian federal universities. Method Documentary research conducted by accessing files available on the Internet. Data were analyzed quantitatively in the form of numbers and percentages. We examined documents from 22 of the 29 federal universities that offered physical therapy programs. Results University extension takes the form of complementary academic activities together with other options such as participating in conferences, specific training courses and working as a teaching assistant. Undergraduate physical therapy courses have a 4,000h to 4,925h course load, of which 0.72% to 8.9% are dedicated to extension activities. Conclusion The data indicate that the insertion of extension activities in undergraduate physical therapy programs offered by Brazilian federal universities needs to be reassessed according to recommended policies and guidelines.

Published: April 2015

Introduction Transcranial direct current stimulation (tDCS) has been used to modify cortical excitability and promote motor learning. Objective To systematically review published data to investigate the effects of transcranial direct current stimulation on motor learning in healthy individuals. Methods Randomized or quasi-randomized studies that evaluated the tDCS effects on motor learning were included and the risk of bias was examined by Cochrane Collaboration’s tool. The following electronic databases were used: PubMed, Scopus, Web of Science, LILACS, CINAHL with no language restriction. Results It was found 160 studies; after reading the title and abstract, 17 of those were selected, but just 4 were included. All studies involved healthy, right-handed adults. All studies assessed motor learning by the Jebsen Taylor Test or by the Serial Finger Tapping Task (SFTT). Almost all studies were randomized and all were blinding for participants. Some studies presented differences at SFTT protocol. Conclusion The result is insufficient to draw conclusions if tDCS influences the motor learning. Furthermore, there was significant heterogeneity of the stimulation parameters used. Further researches are needed to investigate the parameters that are more important for motor learning improvement and measure whether the effects are long-lasting or limited in time.

Published: April 2015

O uso de solventes específicos para extração de proteínas determina o tipo de reação química que ocorre entre os componentes proteicos, principalmente quando estes foram submetidos a tratamentos térmicos como a extrusão termoplástica, uma tecnologia de alta versatilidade, baixo custo, alta produtividade e que não gera efluentes. No entanto, é necessário o uso de concentrações adequadas dos solventes para maximizar a extração das proteínas. Neste trabalho foi avaliada a solubilização de proteínas de análogo de carne a base de isolado proteico de soja e glúten vital, submetidos ao processo de extrusão termoplástica a baixa (23%) e alta (60%) umidade. Os solventes utilizados foram: tampão fosfato (pH 7,5) de 10, 20, 40, 60, 80 e 100mM, dodecil sulfato de sódio de 1, 2, 3, 4 e 5%, β-mercaptoetanol de 1, 2, 3 e 4%, Triton X-100 de 1, 2, 3 e 4% e ureia de 6, 7, 8, 9 e 10M. Todos os reagentes foram dissolvidos ou solubilizados em tampão fosfato 40mM (pH 7,5). Os resultados mostraram que as maiores extrações proteicas foram obtidas com o uso de 40mM de tampão fosfato, 2% de dodecil sulfato de sódio, 2% de β-mercaptoetanol, 3% de Triton X-100 e 7M de ureia

Published: April 2015

OBJETÍVO: El artículo analiza los marcos interpretativos de 82 niños/as (10-12 años) y de 10 madres/1 padre, sobre obesidad y sobrepeso, en dos colegios de Valencia (España). MÉTODOS: Se trata del estudio piloto de un proyecto de investigación cualitativa. Con los niños se usaron cuestionarios de respuesta abierta y elaboración de obras de teatro y cuentos, mientras que con los padres se realizaron grupos de discusión. Se tuvieron en cuenta aspectos como: diferencias de género, atributos negativos y formas de discriminación. En el caso de los padres, se propuso la cuestión de las causas y posibles soluciones del problema en relación a las existentes. RESULTADOS: Entre los niños/as emergieron términos negativos asociados al sobrepeso, presentando una mayor focalización corporal en el abdomen los niños y una notable importancia de la estética las niñas, unida a una percepción más amplia de los efectos del sobrepeso en la sociabilidad. Entre los padres, la preocupación tuvo una preponderancia en los efectos psicológicos del sobrepeso en sus hijos por encima de las consecuencias para la salud (solo en casos graves de obesidad). CONCLUSIÓN: La percepción de los padres sobre las posibles soluciones mostró la clara influencia de los discursos nutricionales, resultado de campañas de concienciación, así como el escaso conocimiento de otras posibles formas de intervención con mayor énfasis social o participativo.

Published: April 2015

OBJECTIVE: Estimate the intake of phenolic compounds by the Brazilian population. METHODS: To estimate the average per capita food consumption, micro data from the National Dietary Survey and from the Household Budget Survey from 2008 to 2009 was analyzed. The phenolic content in food was estimated from the base of Phenol-Explorer. It was chosen according to compatibility and variety of food items and usual method of preparation. RESULTS: The Brazilian population consumed, on average, 460.15 mg/day of total phenolic compounds, derived mainly from beverages (48.9%), especially coffee and legumes (19.5%). Since this analysis of classes of phenolics it was possible to observe an intake of 314 mg/day of phenolic acids, 138.92 mg/day of flavonoids and 7.16 mg/ day of other kinds of phenolics. Regarding the variables studied this present study shows that those men who live in the countryside and in the northeastern region of the country had a higher consumption of phenolic compounds. Besides, consumption was higher by adults and the elderly, the medium income classes, the population with incomplete and complete primary education and those with adequate nutrition and also overweight status. CONCLUSION: The intake of phenolic compounds can be considered low, especially where consumption of fruit and vegetables is insufficient. We can conclude that coffee and black beans were the best contributors to phenolic intake.

Published: April 2015

The aim of this study was to evaluate the combining ability of popcorn lines and hybrids with favorable traits for baby corn production, using lines extracted from the major genotypes of the Brazilian germplasm. From nine popcorn lines, derived from the genotypes Zélia, CMS 42, CMS 43, UEM M2, Zaeli and IAC 112, 36 single-cross hybrids were obtained without reciprocals. In partial diallel crosses, 25 single-cross hybrids were obtained, derived from crosses of five lines of the Zaeli (group I) with five lines from IAC 112 (group II). We recommend using lines derived from Zaeli and CMS 42 in hybrid breeding programs for higher ear yields. The lines P9.5.1 and P9.5.5 (group I) and P8.3 and P8.5 (group II) can be recommended for recombination within each group and for the formation of two synthetic populations for recurrent selection, in order to increase ear yield.

Published: April 2015

The aim of this study was to identify the phases of water absorption during germination of Carica papaya seeds and evaluate the influence of alternating temperature and accelerated aging on mobilization of reserves during germination. Weight gain was evaluated, obtaining the imbibition curve. Phase I of germination comprises the period from zero to five hours; phase II, from five to 120 hours; and phase III begins after 144 hours. Seeds were subjected to the germination test under temperatures of 25 ºC and of 20-30 ºC (16/8 h), and before and after accelerated aging (43 °C / 72 h). During the germination test, at initial time, after 4, 10, 120, and 240 hours of soaking, we determined the levels of soluble sugars, starch, lipids, and total proteins. Greater germination was observed under alternating temperature. Under this condition, there is reduction of carbohydrates, lipids, and proteins in phase I, and fluctuations in lipid levels, and an increase in protein levels during phases II and III. Mobilization of lipids in papaya seeds is not influenced by accelerated aging, but the seeds subjected to aging have lower protein content in phase III.

Published: April 2015

PURPOSE: To translate the Munich Music Questionnaire (MUMU) to Brazilian Portuguese, to adapt it culturally, and to describe the results obtained among adult users of cochlear implant (CI). METHODS: We translated the questionnaire to Brazilian Portuguese, reviewed the grammatical and idiomatic equivalences (back-translation), and adapted it from a linguistic and cultural perspective. The resulting version of this process was applied among adult CI users through direct interviews. RESULTS: The Brazilian Portuguese version of MUMU was applied to 19 adult CI users with postlingual hearing loss, who had been users of the device for at least one year. The answers to the questionnaire were analyzed by distribution of frequency and percentage of occurrence in each question. The results showed a decrease in the frequency of CI users that listen to music, comparing the period before hearing loss and after the CI. Regarding the role that music played in the life of each participant, the responses did not score change, so the music remained being an important factor in the life of the evaluated subjects, even after the CI. CONCLUSION: The subjective evaluation tool MUMU was translated and culturally adapted to the population studied. In Brazilian Portuguese, it was called Questionário de Música de Munique. The study showed its applicability in the daily monitoring of CI users, thus providing a profile of the activities related to music in everyday life.

Published: April 2015

PURPOSE: To investigate the behavioral and social competency profiles of individuals who stutter and to compare them with persons who do not stutter, according to their parents; to correlate the behavioral and the social competence performances with the severity of stuttering. METHODS: Sixty-four participants, aged 6 to 18 years, of both genders, were divided into two groups: the study group (SG), composed of 32 individuals with persistent developmental stuttering, and the control group (CG), composed of 32 fluent individuals. The procedures used were fluency assessment, stuttering severity instrument, and the Child Behavior Checklist inventory. RESULTS: In the behavioral profile of the SG, the mean of the total score and that of the internalizing problems were classified as clinical. The comparison between the groups showed differences in the behavioral profile concerning the total score, and in the internalizing and externalizing problems; and in the social profile, concerning the total score and activity scale. There were no statistically significant differences in the scales among the mild, moderate, and severe stuttering. CONCLUSION: According to the information provided by parents, children who stutter showed peculiar behavior and social competence, with a higher tendency to manifest alterations in this area, in comparison to those who do not stutter. Fear, nervousness/tension, guilt, anxiety, perfectionism, and worry were the most frequent alterations in relation to the behavior, whereas damages in the social field and in the habitual communication situations characterized the social competence of persons who stutter.

Authors: Chacon Lourenço , Villega Cristyane de Camargo Sampaio
Published: April 2015

PURPOSE: (1) To verify the existence (or not) of hesitation marks in the beginning of utterances in children's discourse; and (2) to determine to what extent the presence/absence of these marks could be explained by retrievable facts in the production conditions of their discourses. METHODS: Interview situations with four children aged 5-6 years attending Kindergarten level II in a public preschool at the time of the data collection were analyzed. The interviews were recorded on audio and video, inside a soundproof booth, with high fidelity equipment. Afterwards, the recordings were transcribed by six transcribers that were specially trained for this task. Transcription rules that prioritized the analyses of hesitations were used. For the analysis of retrievable facts in the production conditions of children's discourse, the dialogic pair question-answer was adopted. RESULTS: A correlation between presence/absence of hesitation in the beginning of utterances in children and type of question (open/closed) made by the collocutor was observed. When the question was closed ended, the utterances were preferably initiated without hesitation marks, and when the question was open ended, the utterances were preferably initiated with hesitation marks. CONCLUSION: The presence/absence of hesitation marks in the beginning of utterances in children was found to be dependent on the production conditions of their discourses.

Published: April 2015

PURPOSE: To investigate the association between home environment resources and the school performance of children from a public school in Belo Horizonte, Brazil, enrolled in the fourth year of the second cycle of Elementary School. METHODS: This is a cross-sectional descriptive study in which 48 children aged between 8 and 12 years old participated. It included 28 boys, 20 girls, and their respective guardians. The children were evaluated in hearing and school performance regarding reading, writing, and arithmetic. In the home environment, the resources that promote proximal processes, activities that indicate stability in family life, parent's practices that promote a family-school connection, the resources that may contribute to the development of academic learning, the child's health, the presence of altered communication, family literacy, and socioeconomic data were assessed. RESULTS: There is a relationship between the home environment resources and the academic performance in reading and writing (for all categories of the Home Environment Resources Scale, HERS). The statistical relationship between performances in arithmetics was found in two of HERS' categories: home environment resources and family-school connection. CONCLUSION: The home environment influenced the learning development of the assessed children.

Published: April 2015

PURPOSE: To investigate the process of fatigue in orbicularis oris muscles by analyzing the median frequency of electromyographic signal and the referred fatigue time, according to the breathing mode and the facial pattern. METHODS: The participants were 70 children, aged 6 to 12 years, who matched the established criteria. To be classified as 36 nasal-breathing and 34 mouth-breathing children, they underwent speech-language, otorhinolaryngologic, and cephalometric evaluation. For the electromyographic assessment, the children had to sustain lip dumbbells weighing 40, 60, and 100 g and a lip exerciser, until the feeling of fatigue. Median frequency was analyzed in 5, 10, 15, and 20 seconds of activity. The referred time of the feeling of fatigue was also recorded. Data were analyzed through the analysis of variance - repeated measures (post hoc Tukey's test), Kruskal-Wallis test, and Mann-Whitney U-test. RESULTS: A significant decrease in the median frequency from 5 seconds of activity was observed, independently from the comparison between the groups. On comparison, the muscles did not show significant decrease. The reported time for the feeling of fatigue was shorter for mouth-breathing individuals. This feeling occurred after the significant decrease in the median frequency. CONCLUSION: There were signals that indicated myoelectric fatigue for the orbicularis oris muscles, in both groups analyzed, from the first 5 seconds of activity. Myoelectric fatigue in the orbicularis oris muscles preceded the reported feeling of fatigue in all groups. The account for fatigue time was influenced by only the breathing pattern, occurring more precociously in mouth-breathing children.

PURPOSE: To analyze the self-reported outcomes after hearing aid fitting among individuals in the northern region of Minas Gerais and associated factors. METHODS: A cross-sectional and analytical study with a random sample of adults and elderly attending the public health care service was conducted in the northern region of Minas Gerais (86 municipalities), Brazil. Study's participants answered International Outcome Inventory for Hearing Aids (IOI-HA) questionnaires. Data were analyzed descriptively and analytically with Poisson regression analysis. RESULTS: We interviewed 272 adults and 112 individuals reported not using their hearing aids regularly. The mean of IOI-HA global score was lower than expected. The individual's relationship with their hearing aid (Factor 1) was worse than the individual's relationship with their environment (Factor 2). Lower global scores were statistically associated with no work. CONCLUSIONS: The observed scores for the study's population are lower than those recorded in other studies. The results suggest that there are limitations in the fitting and follow-up of individuals who received hearing aids.
Rapid naming, phonological memory and reading fluency in Brazilian bilingual students
Authors: Fleury Fernanda Oppenheimer , Avila Clara Regina Brandão de
Published: April 2015

PURPOSE: To characterize the performance of Brazilian students exposed to two languages in reading fluency, phonological memory, and rapid naming, according to grade level, and to investigate correlations between these variables. METHODS: Sixty students took part in this study (50% female), enrolled in the third to the fifth grades of two elementary schools of the city of São Paulo. They constituted two groups - bilingual group: 30 Brazilian children whose mother tongue and language spoken at home was Brazilian Portuguese and who were daily exposed to English at school for a period not shorter than three years; monolingual group: 30 students, from a monolingual Brazilian elementary school, who were paired by gender, age, and grade level with the bilingual students. Foreign children, children with complaint or indication of speech and language disorder, or who had been retained were excluded. A rapid automatized naming, pseudoword repetition, and oral reading tests were administered. The bilingual children were assessed in both languages and their performances were compared among themselves and with the monolingual group, which was only assessed in Brazilian Portuguese. RESULTS: The bilingual group showed better performance in English, rapid naming, and pseudoword repetition tasks, whereas Brazilian Portuguese, in reading fluency. A higher number of correlations were found in Brazilian Portuguese. CONCLUSION: The results suggest that the acquisition of a second language may positively influence the abilities of rapid naming, reading rate, and accuracy. Brazilian bilingual students performed better in tasks of phonological memory in English and Brazilian Portuguese performed better in reading fluency. Different correlation patterns were found between the rapid naming, accuracy, and reading rate, in the bilingual group analysis, in both languages.

Published: April 2015

Este trabalho apresenta o problema de equilíbrio espacial de preços para produtos sazonais num ambiente de competição perfeita sujeito a estoque regulador sem banda de preços. O problema é formulado como um modelo de programação não linear. A solução é obtida com o uso de um algoritmo de projeções, o qual é aplicado a um caso numérico ilustrativo. Os resultados são discutidos e, para fins de comparação, são confrontados com o caso em que não existe o estoque regulador.
O Séminaire de Jacques Derrida por quatro caminhos
Authors: Michaud Ginette
Published: April 2015

Quais são as dificuldades de um trabalho de edição dos Seminários de um filósofo como Jacques Derrida? Quais são os riscos com os quais é necessário se defrontar? Na busca de responder a questões como essas, tratando especificamente da publicação dos dois volumes do Séminaire La bête et le souverain, o presente ensaio desenvolve uma reflexão percuciente acerca do arquivo, do luto, da herança e, ainda, sobre a improvisação, a figura do leitor, a partir do modo como se colocam na obra de Derrida. Durante quarenta anos de ensino, o filósofo nos legou uma "obra de pensamento" que pode, agora, ser confrontada, senão transformada, deslocada pelas publicações dos seus Seminários.
A besta e o soberano: três notas para Derrida
Authors: Bennington Geoffrey
Published: April 2015

Partindo do entrelaçamento original entre os conceitos de soberania e bestialidade elaborado por Jacques Derrida nos seminários de A besta e o soberano, este ensaio investiga as formas pelas quais tal entrelaçamento é pensado por três filósofos que se debruçaram sobre o tema. Em Aristóteles, está em questão a tensão no conceito de homem ideal, aquele que, por ser ideal, não é naturalmente político - politikon zoon- e, portanto, como um deus ou uma besta, fica acima ou abaixo da polis. Sendo superior, é ele quem fará a justiça e as leis, não podendo, consequentemente, fazer parte de um estado. Em Bataille, trata-se de avaliar o modo como o filósofo elabora a associação entre a soberania e a morte, numa lógica de autoperversão ou autoimunidade que fará aflorar a inumanidade do soberano, fazendo com que a soberania seja um constante pôr-se à morte do soberano. Em Heidegger, é possível notar como o filósofo, a partir da leitura de Antígona, propõe e pensa a violência original do conceito de soberania na figura do hupsipolis apolis, isto é, daquele que, por honrar e obedecer as leis do estado, quebrará essas leis e será banido da polis, demonstrando a inseparabilidade entre os conceitos de soberania e bestialidade.

O sujeito diante da aceleração e da ilimitação contemporânea
Authors: Haroche Claudine
Published: April 2015

A ampliação dos fluxos tecnológicos, com sua velocidade e crescente aceleração, tem acompanhado e até mesmo provocado a emergência de um mundo líquido e doravante globalizado, em que real e virtual, profundamente imbricados, tendem a ser desprovidos de limites. A construção do sujeito na modernidade bem como as condições da vida psíquica e social foram assim profundamente perturbadas. As condições contemporâneas são dominadas por fluxos sensoriais e informacionais contínuos que, estimulando e até mesmo impondo a instantaneidade e a imediatidade, embaraçam a possibilidade de temporização e de reflexão ao longo do tempo. Esses fluxos provocam efeitos sobre as maneiras de ser, de viver, de pensar, os modos de representação de si e do outro e ainda sobre as maneiras de sentir e de perceber: ao exercer uma pressão contínua sobre os indivíduos, provocam a perda de critérios estáveis e o princípio de limites tangíveis ou pelo menos perceptíveis no espaço e no tempo. Os fluxos contínuos levam o indivíduo a formas de propriedade de si ilimitadas, ao mesmo tempo em que induzem um estreitamento do espaço interior: induzem uma insegurança psíquica e social profunda e, além disso, formas de angústia inéditas.
Role of distributed storage in a 100% renewable UK network
Authors: Alexander Marcus Joseph , James Patrick
Published: April 2015

This study considers generation and demand challenges of a 100% renewable UK electricity grid and poses the question whether this can be addressed through the use of distributed energy storage. To explore this issue, hourly demand and electricity generation profiles for a year have been constructed for a variety of renewable sources and demand scenarios. Alongside baseline projections, further scenarios have been produced that include extensive uptake of electric heat pumps for domestic heating and hot water, as well as moderate uptake of electric vehicles. It is proposed that these technologies are used on a local scale to help integrate the additional renewable electricity generated within a predetermined zone of the electricity network. Analysis has been carried out to determine the pinch points in the UK network where renewable electricity generation is greater than local electricity demand. From this, consideration has been given to understanding the real impact distributed energy storage in the form of heat pumps and electric vehicles can have in helping balance a 100% renewable UK electricity grid. Initial results have found that, depending on the demand scenario and location on the network, there is the potential to accommodate up to 50% of the excess electricity generated.
Reassessing the financial and social costs of public transport
Authors: Li Xucheng , Preston John
Published: April 2015

Increasing urbanisation around the world has raised the passenger demand for public transport. Many public transport technologies are available to meet this demand. This paper develops a spreadsheet cost model that simulates public transport modes operated on a 12-km route and incorporates a new public transport mode, the straddle bus. Previous research has assumed that demand is exogenous (externally fixed). This work investigates the impact of endogenous demand, which varies with service level characteristics. Elasticities for passenger waiting time and in-vehicle time are used to assess actual passenger reactions to the attractiveness for different public transport technologies at different levels of demand. The result of this work shows the lowest average social and operator cost public transport technologies for different ranges of demand. Based on the default values used in the spreadsheet model, smaller size vehicles (e.g. personal rapid transit and minibus) dominate the low passenger demand range due to their short waiting times. Single-decker and double-decker buses appear to be the best option for a demand of around 3000–60 000 passengers per day (ppd), followed by the straddle bus (from around 60 000 to 100 000 ppd). The great capacity but high capital costs of underground make it the most cost-effective technology when other technologies are experiencing high congestion, with demand levels higher than 100 000 ppd.
A search for relict ribonucleotide and amino acid sequences that played a key role in the development of the ribosome and modern protein diversity
Authors: Skoblikov N.E. , Zimin А.А.
Published: April 2015

The study presents the results of analysis of protein sequence database for prokaryotic microorganisms, which revealed a conservative peptide sequence element of 11 amino acid
residues in 20 loci of 16 functionally and phylogenetically differing conservative proteins from representatives of various taxa. This amino acid motif IKAVRELGLER is presumably
one of the Last Universal Peptide Ancestors (LUPAs). A fragment of ribosomal RNA (part of the A-site including stems H92, H90 and H93 of the peptidyl transferase center, PTC)
translated from one of the potential reading frames is likely to be a source of genetic information for this sequence. We define this m/rRNA fragment with a function of a template
for LUPA synthesis as the Last Universal RiboNucleic Ancestor (LURNA). We assume that LURNA and the peptides translated from its sequence were a source of the modern diversity of peptides.
