Incidental finding of a Sertoli-Leydig cell tumor in a postmenopausal woman with complex endometrial hyperplasia
Authors: Kim Yeejeong , Lee In Ok , Chung Jae Eun
Published: September 2018

Sertoli-Leydig cell tumors (SLCTs) arise from the non-germ cell component of the ovary and typically present in young women with evidence of hyperandrogenism such as precocious puberty, amenorrhea, hirsutism and virilization. It is very rare accounting for less than 0.2% of all ovarian tumors, and because of the rarity, no standardized treatment approach has reached a consensus. The prognosis is generally good with complete reversion of symptoms after surgery, although some cases have been reported to be malignant. Recently the need for DICER1 mutations testing in paediatric patients has been emphasized for the surveillance of possible synchronous tumors and affected family members. Authors present here a case of Sertoli-Leydig cell tumor incidentally found while performing a hysterectomy with bilateral salpingo-oophorectomy in a postmenopausal woman with endometrial hyperplasia that caused intractable vaginal bleeding.

Published: September 2018

Rectus sheath hematoma (RSH) is a rare but potentially life threatening complication of caesarean delivery. The nonspecific nature of entity, lower incidence of disorder and acute presentation may posses’ difficulty in timely recognizing this. Present patient presented as acute abdominal pain 38 hours post caesarean section. This is an attempt to increase the awareness of this rare but potentially grave condition, as timely diagnosis and fast intervention saved present patient.
Torsion of dermoid cyst in a perimenopausal woman: a case report
Authors: Radhika Kondareddy , Singh Sonam , M. Munikrishna
Published: September 2018

Mature cystic teratoma comprise 20-30% of all ovarian tumours. They are mostly seen in patients between 20 and 40 years of age and are mostly asymptomatic. Incidence of malignancy is high in perimenopausal and postmenopausal group. Here, authors report a case of torsion of dermoid cyst presenting unusually in a 45-year-old perimenopausal woman with acute abdomen. A 45-year-old perimenopausal woman presented with lower abdominal pain of 8 hours duration and 3-4 episodes of vomiting. Abdominal examination revealed a regular, firm to cystic, tender abdomino-pelvic mass corresponding to the size of 28 weeks gravid uterus by palpation. Abdominal ultrasonography revealed the presence of right ovarian cyst measuring 12.9x12.8x10.1 cm. Total abdominal hysterectomy with bilateral salpingo oopherectomy was done. Histopathological examination confirmed mature cystic teratoma. Although mature cystic teratoma is rare after 40 years age, especially in perimenopausal women and are usually malignant in that age group, it can have an unusual age presentation at 45 years with benign nature as in present case.
Neonatal pertusis with classical whoop: an unusual scenario
Authors: Joshi Payas , Bhatia Sumit , Kishore Jay , Jhaz Chetnanand
Published: September 2018

Pertusis affects all the age groups but is most severe in neonates and early infancy and may even cause mortality. Clinical presentation of neonatal pertusis is varied and thus knowing the spectrum of clinical presentation is vital for early diagnosis. Unlike older children, most of the times neonatal pertusis has an atypical presentation and classical presentation is very rare. Here we present such a rare case of neonatal pertusis who presented with classical symptoms of pertusis.
A clinical study to determine the effects of adenoidectomy in cases of secretory otitis media in school going children
Authors: Rama Sridhar M.
Published: September 2018

Background: Secretory otitis media (SOM) is common otological symptom in children. If left untreated it leads to hearing and speech impairment. Surgical management is effective in serious cases. The present study was done with the objective to assess the effect of adenoidectomy by pure tone and impedance audiometry in cases of SOM with hypertrophied adenoids.

Methods: This study comprised 50 cases, who were aged 5-12 years and diagnosed as SOM with adenoid hypertrophy. It was carried out for a period one and half years from December 2015 to July 2017 at Mamata Medical College and Research Hospital, Khammam, Telangana. After detailed history and clinical examination, investigations such as pure tone audiogram, impedance audiometry, X-ray nasopharynx and diagnostic nasal endoscopy were carried out to confirm the diagnosis. All patients were posted for adenoidectomy and when indication was present tonsillectomy was also done. They were followed up at 1st, 3rd and 6th month for pure tone audiometry and impedance was done at 6th month of surgery.

Results: In this study, maximum number (60%) of cases belonged to 5-7 years age group, with slight male preponderance (56%). On pure tone audiometry 68% had 16-25 dB and 32% had 26-40 dB hearing loss and average being 24.95 dB. On impedance only 14% had peak preoperatively. Postoperatively, no peak/peak conversion was seen in 33% of cases and mean A-B gap improvement at 1st, 3rd and 6th month was 13 dB, 13.2 dB and 12.7 dB respectively (p value is 0.0001,<5%) when compared to preoperative findings.

Conclusion: Adenoidectomy is effective in the management of middle ear infection in children having hypertrophied adenoids.
The missing grains in Madura foot: imaging to the rescue
Authors: V. P. K. Gopinath , C. M. Ali Rishad , P. M. Farisa
Published: September 2018

Mycetoma or Madura foot is a chronic localized granulomatous infection caused by varied species of fungi or actinomycetes clinically diagnosed by active discharging sinuses containing ‘grains’. In atypical presentations or patients unwilling for invasive investigations, imaging essentially plays a key role in diagnosis and helps to differentiate actinomycetoma from eumycetoma. Here we present such an atypical case of unilateral foot swelling without sinuses–cryptic mycetoma. This 69 year old male from Kerala had a swelling over the left foot following trauma initially painless. An x-ray taken showed normal underlying bones with mild soft tissue swelling. To evaluate further USG was taken which showed fine hyperechoiec foci settled at the bottom of cavities highly suggestive of mycetoma. For confirmation USG guided biopsy was taken but was inconclusive. As patient was not willing for repeat biopsy, we advised non invasive MRI that revealed classical ‘Dot In Circle’ sign specific for mycetoma. The distinction that makes the case stand out is its absence of classical picture of discharging sinuses and the fact that imaging rather than histopathology helped confirm the diagnosis in mycetoma.
Transformasi Paradigma Teologi Teosentris Menuju Antroposentris:Telaah atas Pemikiran Hasan Hanafi
Authors: Gufron M.
Published: September 2018

Hassan Hanafi is one of the contemporary Islamic scholars who gives considerable attention to classical Islamic theology (kalam Islam). For him Islamic theology, such as the Ash’ari’s Kalam, cannot be proven scientifically also philosophically. Classical Islamic theology practically cannot be used as a view that can motivate the increasing of concrete actions in human life. This is caused by the compilation of classical Islamic theology tends not to be based on the pure awareness and the values of human actions. So that this creates a split between the theoretical faith into the practical faith of ummah. In turn, this conditions create the multiple moral attitudes or secretism of personality that makes Islamic society worse in poverty, oppression, backwardness and ignorance. For this problems, Hassan Hanafi offered a reconstruction that is to change a more grounded theological paradigm; that is from theocentric (God is the central of everything) to be anthropocentric (humanbeing is the central of everything). If the first paradigm sees world affairs as a matter of God, then the second paradigm sees world affairs as human affairs.
Muhammad Shalih as-Samarani dalam Kacamata Masyarakat Muslim Milenial
Authors: Misbah Aflahal
Published: September 2018

Muhammad Salih As-Samarani was one of the Nusantara's intellectual figures of the past which was associated with the term 'Islam Nusantara'. This figure, in some of 'Islam Nusantara' literatures, is considered as one of the representative figures to explore and discover the foundation of 'Islam Nusantara'. His actions and thoughts in the 19th century in Java, which were able to connect Mecca and Pesantren and Pesantren and society, were indeed not negligible in the effort to build 'Islam Nusantara' argument. Recognition of the As-Samarani figure, in fact, is not only a field of scientific study for scholars, but also for ordinary people who are also increasingly keen to introduce As-Samarani in public. In this paper, as a preliminary study, the author tries to focus on seeing how As-Samarani is represented in public by ordinary people through YouTube. Almost all of the videos on Youtube which try to re-display As-Samarani figure appeared after the 'Islam Nusantara' become the 33rd NU Congress in Jombang. As-Samarani's figure on Youtube shows that along with the affirmation of the term 'Islam Nusantara', the As-Samarani figure is even more interesting for ordinary people, especially in media of his magical power contexts (such as turning stones into gold, meeting Imam Ghazali, his goats are able to defeat tigers), not his actions and thoughts, or more specifically perhaps his writings.
Effects of Congruency on Bereitschaftspotential While Performing a Bimanual Motor Task
Authors: McGowan Meghan , Hémond-Hill Camille , Nakazawa Justine
Published: September 2018

The bereitschaftspotential (BP)—also known as the readiness potential—is a measure of brain activity that precedes voluntary movement by approximately one second in the supplementary motor area and the contralateral primary motor cortex. Motor task reaction time for bimanual task performance is affected by both the individual and the environment; however, it is unclear whether motor task reaction time (as measured via the BP) is significantly affected by congruency. A congruent motor task is an ipsilateral stimulus (e.g., a stimulus on the right is responded to by the right hand), and an incongruent task is a contralateral stimulus (e.g., a stimulus on the right is responded to by the left hand). Congruency is re-emerging as an important topic in motor learning as it may require different levels of cortical processing. The purpose of this study was to examine the effect of congruency on the BP. Participants were asked to complete the computer task, Keyboard Hero, where they pressed keys with both their left and right hands in response to discrete congruent and incongruent stimuli. A MUSE™  apparatus recorded brain activity 1000 ms prior to, and 1000 ms after each stimulus. Results from every participant for the incongruent and congruent trials were averaged and compared using a grand average waveform. Means of accuracy (how often participants pressed the key correctly) and BP for each condition were averaged and compared using a 95% Confidence Interval (CI). Across congruent and incongruent conditions, a non-significant difference (p > 0.05 ) was found in BP (p > 0.59 ), accuracy (p > 0.64 ), and BP within −200  ms to 200 ms (p > 0.31 ). BP and mean accuracy scores were not significantly different between congruent and incongruent conditions, which may be due to only minute differences in brain activity or due to the study’s design. Further research should analyze individual variations of the present study, such as stimulus location, differences in the responding limb, correctness of responses, and the sensory modality being tested
GAZETA DE NOTÍCIAS: JORNAL FOMENTADOR DA CULTURA E DA LITERATURA PORTUGUESA NO RIO DE JANEIRO

Published: September 2018

No início do século XX, a cidade do Rio de Janeiro era uma importante afluente da colônia portuguesa no Brasil. Esta desempenhava um papel de destaque, estando presente, de forma ativa, nas principais decisões da cidade, por meio de suas atividades sociais, artísticas, políticas. Para atender a esse público, os periódicos da cidade contavam com a participação de literatos e jornalistas portugueses. Dentre esses jornais, destaca-se a Gazeta de Notícias (1875-1942). O jornal contava com uma intensa participação de autores portugueses e proporcionava seções que abordavam especificamente assuntos lusitanos. Em vista disso, objetivamos comentar a presença de seções e textos sobre Portugal nas páginas da Gazeta de Notícias, durante os anos de 1901 a 1905, com destaque para as crônicas de D. João da Câmara, que se constituem como fomentadora da cultura e valores portugueses no jornal.
NARRATIVAS JORNALÍSTICO-LITERÁRIAS E VISIBILIDADE
Authors: Werneck Ladeira Réche Daniela
Published: September 2018

O objetivo deste artigo é analisar como os testemunhos das vítimas do genocídio em Ruanda e na Guerra de Albergues, na África do Sul, no pré-fim do apartheid, as ajudaram a escapar da dupla invisibilidade a que foram submetidas: porque a história africana tem sido negligenciada pelo Ocidente e porque tornaram-se fantasmas em suas próprias vidas, uma vez que atravessados por um passado de dor extrema. Para isso, são discutidos dois livros escritos por jornalistas: Gostaríamos de informá-lo que amanhã seremos mortos com nossas famílias: Histórias de Ruanda, de Philip Gourevitch, e O clube do bangue-bangue: Instantâneos de uma guerra oculta, de Greg Marinovich e João Silva. Embora elas tenham sido construídas a partir do testemunho indireto, no qual as vivências da violência são mediadas pela voz dos narradores, sustenta-se que essas vítimas foram reconhecidas nos relatos ora analisados como sujeitos. Suas vozes, silenciadas pelo trauma e pelo relato oficial, foram ouvidas pelos jornalistas, tornando possível a sobrevivência e permanência na história.

Authors: Barbieri Mickael Braga
Published: September 2018

Este artigo busca compreender as repercussões da morte do crítico literário e personalidade brasileira Antonio Candido sob o ponto de vista de um acontecimento. Foram selecionadas para a análise as notícias sobre o falecimento publicadas por cinco meios de comunicação através do Facebook, sendo dois jornais, duas revistas e um portal de notícias, bem como comentários dos usuários da rede social que se manifestaram sobre a figura de Antonio Candido. A metodologia utilizada baseou-se na individuação do acontecimento em três processos: descrição, narração e configuração de um fundo pragmático. Foi possível notar os diferentes enquadramentos que cada veículo de comunicação acionou para falar da morte do crítico e sua trajetória, fenômeno presente também nos comentários que parecem retratar a intolerância e a polarização sintomática do atual momento político pelo qual passa o Brasil

O CHEIRO DO RALO E AS COMPLICAÇÕES DA FORMA ROMANESCA NO HORIZONTE DA INDÚSTRIA CULTURAL
Authors: Parecis de Oliveira Marília Corrêa
Published: September 2018

O presente artigo discutirá algumas concepções teóricas sobre a forma romanesca e irá relacioná-las com a análise do romance O cheiro do ralo (2002), de Lourenço Mutarelli. Pretende-se questionar a noção de gênero problemático atribuída ao romance por Lukács (2000), entendendo que, conforme Fehér (1972), o romance não seria problemático, mas ambivalente. Objetivamos mostrar, ainda, como a obra analisada não comporta apenas as complicações propostas pelos teóricos sobre a forma do romance, mas abarca, também, as complexidades do contexto inescapável da indústria cultural.
SOBRE PINTURA E POESIA

Published: September 2018

O objetivo deste texto é discutir a relação – sempre atual e norteadora de novos debates – entre pintura e poesia, Ut pictura poesis, desde o seu surgimento, na Antiguidade, até nossos dias. Para isso, nos valeremos de diversas leituras acerca desta relação: Du Bos (2005), Delacroix (2005), Lessing (2005), Oliveira (1987), Hansen (2006), etc., que analisam as diferenças e igualdades entre as várias formas de expressão e produção das respectivas artes como forma de compreender a condição artística de cada uma. Com isso, veremos que esta relação tão antiga e profícua, no decorrer do tempo, sofreu profundas e constantes transformações. Ao ponto, que podemos constatar que, hoje, a relação pintura e poesia converteu-se na relação entre poesia e imagem, configurando, dessa maneira, o processo de transformação e evolução da tradição Ut pictura poesis. Tal perspectiva nos permite vislumbrar o processo que possibilita que formas artísticas do passado continuem atuantes no presente, sendo o exemplo mais notável disso a relação entre barroco e modernidade, estudada e analisada por Hatherly (1995).

cardiovascular effects of oral appliances in obstructive sleep apnea
Authors: Agaltsov M. V.
Published: September 2018

Oral  appliances  (ОА)  are  one  of  the  leading  methods  of  effective  treatment  of  sleep-related  breathing disorders. Obstructive sleep apnea (OSA) is a widespread disturbance in the general population. It is closely associated with many cardiovascular diseases (hypertension, cardiac arrhythmias, chronic heart failure, ischemic heart disease). Timely detection and treatment of OSA is an important task in the process of reducing the number of cardiac complications. Modern devices for the treatment of OSA are custom-made devices which allow to change the position of the mandible and its extension providing personalized treatment of snoring and sleep apnea. Changing the degree of the mandible extension, the ОА retains the upper respiratory tract in open position and indirectly stimulates the muscles, determining their tone. The effectiveness of the ОА is evaluated by the complete elimination of all respiratory events (snoring, upper airway resistance syndrome, OSA and hypopnea), as well as the influence on the sleep structure and the wakefulness functioning (excessive daytime sleepiness). The effects of ОА on cardiovascular diseases are of great importance, as they showed a decrease in both systolic and diastolic blood pressure, as well as a positive effect on the impaired endothelial function. Among all the treatment options, ОА take the leading positions, only slightly inferior in effectiveness to noninvasive ventilation, so called CPAP therapy. Regarding the long-term adherence to therapy (which is especially important in the cardiovascular prevention) оral appliances exceed CPAP therapy. Thus, the OA therapy is one of the leading therapeutic directions in modern sleep medicine for obstructive sleep-related breathing disorders.
Рredictors and markers of experimental vasorenal hypertension onset in the model “2 kidneys, 1 clamp”
Authors: Kuzmenko N. V. , Tsyrlin V. A. , Pliss M. G.
Published: September 2018

The aimof the study was to analyze the influence of the baseline systolic blood pressure (SBP), the length of beat-to-beat interval (RR) and the components of the heart rate variability (HRV) spectrum on the development of vasorenal hypertension in the model “2 kidneys, 1 clamp” in Wistar rats. Also we investigated the relationship between anxiety and parameters of hemodynamics in intact animals using the “open field” test and the correlations between SBP level, RR duration and the components of the HRV spectrum in both intact animals and animals with renal artery ischemia.Design and methods. We recorded hemodynamic parameters on the tail of awake rats. In the HRV analysis, a low-frequency component (LF), a high-frequency component (HF) and a sympathetic-vagal balance (LF/HF) were calculated.Results. In normotensive rats the normal high SBP is accompanied by tachycardia and increased anxiety in “open field” test. The baseline values of SBP, RR interval and HRV spectrum components do not influence the development of unilateral vasorenal hypertension. In the development of unilateral vasorenal hypertension, weakened parasympathetic effects on cardiac function were observed, as evidenced by a decrease in the RR interval duration and HF component of the HRV spectrum in animals with developed hypertension, as well as an increase in the LF/HF component of HRV in clamped rats.Сonclusions. Individual increased anxiety of normotensive animals does not affect the development of vasorenal hypertension in the model “2 kidneys, 1 clamp”.
Selling Product or Selling Gender: Toy Advertisements and Child Gender Identity
Authors: Andreu Lauren , 2015 Class of
Published: September 2018

Significant research has been conducted on how well children understand advertisements and the effect advertisements and television have on a child. However, there is not a large amount of research on the relationship between toy advertisements and children’s choices for play and gender identity. This paper will attempt to bring together multiple aspects of research that touch on all of these points to better grasp a full understanding of the topic. The research found that young children identify certain toys as gendered, but that they and their parents are open-minded about playing with many toys specifically marketed to the opposite gender. It was also found children could not provide a true understanding of what an advertisement’s purpose is until they were nine years old.
Evaluation of Health on a Budget: A Health Promotion Program for Women Experiencing Homelessness
Authors: Hackett Autumn , 2016 Class of
Published: September 2018

In 2015, the researcher created "Health on a Budget," a five-session health promotion class to empower homeless women to live heathier lives on a budget. After enhancing the curriculum using the theory of planned behavior (Ajzen, 1991), the researcher reintroduced the program in 2016 and evaluated its effectiveness.

The researcher worked with stakeholders to identify key topics: health literacy in nutrition, portion control, cooking, exercise, and oral and foot hygiene. The researcher created objectives, lesson plans, and evaluation surveys that aligned with the theory of planned behavior. At the conclusion of each session, participants completed a survey that determined the completion of the objectives. Ten women residing at the Center for Transforming Lives shelter in Fort Worth participated in "Health on a Budget" in 2016. As a whole, the participants met all of the knowledge objectives, 80% of the attitude objectives, 80% of the behavioral intention objectives, 40% of perceived behavioral control objectives, and 20% of subjective norm objectives. Overall, the program had the greatest effect on the participants’ knowledge, attitudes, and intentions to perform healthy behaviors. The program was well-received by the participants, and the shelter stakeholders were very pleased with the program development and outcomes. Although the participants met most of the objectives, it is unclear if the women will take the knowledge they have and use it to change their day-to-day behaviors because of the complexity of their environment and circumstances. Changing shelter policies to improve the food environment and the nutritional content of the food would be more effective in promoting the health behaviors of residents in the short term. In the long term, the provision of stable housing would allow women to begin improving their physical, mental, and emotional health through programs like "Health on a Budget."
Reporting Sexual Assault: Review of the Literature Regarding the Decision to Report Sexual Assault

Published: September 2018

This review of the literature investigates the many reasons why a person may choose not to report sexual assault. The pain, trauma, worthlessness, and other extreme emotions that stem from sexual assault are contributing factors in an individual’s choice to report; there are many reasons why a person would choose not to report. From my time spent at The Women’s Center of Tarrant County, I have seen survivors make this difficult decision over and over—some choosing to report, some not. The results of the literature review give new insight to the reporting process our clients may decide to participate in.

Stillness in Four Movements
Authors: Henderson Alden , 2017 Class of
Published: September 2018

Stillness in Four Movements, a dance performance culminating from a year-long research process, investigates conceptions of stillness as movement in a manner similar to the ways John Cage explored silence in music, or the ways Mark Rothko explored the concept of nothingness in visual art. Total stillness is, of course, impossible. Our hearts are always beating, cells are decomposing, and atoms are moving. Nonetheless, this project asks how dance can productively engage with the concept of stillness as choreographic material. Stillness explores the difficulty of engaging with the notion of stillness through choreographic material in four sections that address questions of stillness in choreography.
Long-term survival of uveal melanoma patients after enucleation, depending on molecular genetic aberrations

Published: September 2018

Rationale: In the recent years molecular genetic prognostic factors are becoming very important for predicting the course of uveal melanoma (UM). In clinical practice, molecular genetic methods are used to identify patients with a high risk of metastases.

Aim: To determine the survival of UM patients after enucleation, depending on molecular genetic aberrations.

Materials and methods: Thirty (30) patients with UM aged from 23 to 83 years were examined and treated. In all cases, enucleation was performed. The removed eyes underwent morphological and molecular genetic and cytogenetic analysis (loss of heterozygocity on chromosomes 1, 3 and 8, methylation of the RASSF1A gene, mutations in GNAQ/11 genes, polymorphism of the ABCB1 gene). The median follow-up was 61 months.

Results: The cumulative 3-year survival of the UM patients was 77.8 ± 8.0%, and the 5-year survival 63.0 ± 9.0%. The mean survival time was 52.8 ± 3.9 months. The patients with chromosome 3 monosomy showed significantly lower 5-year survival rates than the patients with partial monosomy and without loss of heterozygocity in chromosome 3 (log-rank test, χ2 = 14.111, p = 0.001). The loss of heterozygocity on chromosomes 1 and 8, the methylation of the RASSF1A gene, the mutations in GNAQ/11 genes, and the polymorphism of the ABCB1 gene were not associated with poorer vital prognosis.

Conclusion: Molecular genetic aberrations play an important role in predicting the course of the tumor process and determining the risk of hematogenous metastasizing in UM patients. The significant role of chromosome 3 monosomy has been proved. Due to the relatively small cohort (30 patients) and the time factor (analysis of 5-year survival), the role of other molecular genetic changes has not been confirmed, which requires an assessment of not only genetic, but also clinical, echographic and morphological prognostic factors.
A importância do educador musical e sua influência na educação infantil
Authors: De Moraes Ana Beatriz Vitoriano , Da Rosa Kalita , Santos Richard Isaac Nunes , De Lima Ailen Rose Balog
Published: September 2018

O presente trabalho pretende refletir sobre a importância e o papel do educador musical na educação infantil. Em linhas gerais, este estudo, através de uma pesquisa bibliográfica descritiva, busca analisar como é introduzida a educação musical, principalmente na educação infantil. Vemos hoje que a educação musical não escapa de conviver e de se defrontar com constantes situações problemáticas que são peculiares ao atual momento. Diferentes práticas espalhadas pelo país são propostas com a intenção de amenizar as necessidades pedagógicas musicais decorrentes da diversidade de concepções, de conhecimento e de mundo. Muitas vezes, o ensino de música nas escolas está diluído em práticas metodológicas diversas, decorrentes da falta de fundamentação teórica consistente ou da formação inadequada do educador musical. A educação musical é um fundamento importante para a construção de uma proposta de ensino que auxilie o indivíduo na compreensão de crenças e valores, na forma de percepção de mundo e do que ele define como importante. Ao final, baseando-se no Referencial Curricular Nacional para a Educação Infantil (RCNEI), de 1998, falaremos da atuação do professor na educação infantil, da importância e da responsabilidade de cumprir os objetivos estabelecidos para as aulas de música. A pesquisa deste tema está diretamente relacionada ao contexto vivenciado pelos realizadores deste artigo, que trabalham com musicalização infantil através do Programa Institucional de Bolsas de Iniciação à Docência (PIBID).

A formação do “autor”, seguindo as ideias da escritora Eni Orlandi, é fomentada por inúmeras características nas quais o ambiente escolar pode atuar, de diferentes formas e frentes, na construção do sujeito. Essas posições podem ser observadas nos escritos de profissionais de Jornalismo que assinam opinião em jornais. Além de contextualizar, de forma panorâmica, o conceito de autoria, este artigo analisa textos de dois articulistas, Mirian Leitão e Reinaldo Azevedo, na tentativa de exemplificar as argumentações teóricas exploradas.

Published: September 2018

Amonium klorida merupakan zat aktif dalam obat batuk hitam yang berfungsi sebagai pengencer dahak. Penentuan kadar amonium klorida dalam sediaan obat menjadi sangat penting untuk uji kualitas produk agar obat memiliki khasiat dan keamanan yang dapat diterima pasien. Berdasarkan Farmakope V penentuan amonium klorida dapat dilakukan dengan metode argentometri. Analisis kadar amonium dalam obat batuk hitam secara argentometri belum tersedia data validasinya. Oleh karena itu perlu dilakukan validasi. Parameter validasi yang dijadikan acuan adalah akurasi, presisi, linearitas, batas deteksi dan nilai estimasi ketidakpastian pengukuran. Berdasarkan hasil yang diperoleh dalam penelitian parameter uji validasi untuk akurasi, ripitabilitas (%RSD), presisi antara (%RSD), linearitas (R2) dan estimasi ketidakpastian pengukuran secara berurutan yaitu sebesar 99,97-104,85%; 0,50-3,40%; 6,58%; 0,9985 dan 1,42 mg/5mL sehingga dapat disimpulkan bahwa metode penentuan amonium klorida dalam obat batuk hitam menggunakan metode titrasi argentometri belum cukup bukti untuk dinyatakan valid karena presisi atau keterulangan belum memenuhi syarat keberterimaan.
Unsupervised Metric Learning Using Low Dimensional Embedding
Authors: Jain Parag
Published: September 2018

Unsupervised metric learning has been generally studied as a byproduct of dimensionality reduction or manifold learning techniques. Manifold learning techniques like Diusion maps, Laplacian eigenmaps has a special property that embedded space is Euclidean. Although laplacian eigenmaps can provide us with some (dis)similarity information it does not provide with a metric which can further be used on out-of-sample data. On other hand supervised metric learning technique like ITML which can learn a metric needs labeled data for learning. In this work propose methods for incremental unsupervised metric learning. In rst approach Laplacian eigenmaps is used along with Information Theoretic Metric Learning(ITML) to form an unsupervised metric learning method. We rst project data into a low dimensional manifold using Laplacian eigenmaps, in embedded space we use euclidean distance to get an idea of similarity between points. If euclidean distance between points in embedded space is below a threshold t1 value we consider them as similar points and if it is greater than a certain threshold t2 we consider them as dissimilar points. Using this we collect a batch of similar and dissimilar points which are then used as a constraints for ITML algorithm and learn a metric. To prove this concept we have tested our approach on various UCI machine learning datasets. In second approach we propose Incremental Diusion Maps by updating SVD in a batch-wise manner.
Unavailable Time Aware Scheduling of Hybrid Task on Heterogeneous Distributed System

Published: September 2018

The resource allocation for tasks in heterogeneous distributed system is a well known NP-hard problem. For the sake of making the makespan is minimized, it is hard to distribute the tasks to proper processors. The problem is even more complex and challenging when the processors have unavailable time and the tasks type are various. This paper investigates a resource allocation problem for hybrid tasks comprising both divisible and bag-of-tasks(BoT) in heterogeneous distributed system when the processors has unavailable time. First, the mathematical model, which minimizes the makespan of the hybrid tasks when the processors have unavailable time, is established. Second, we propose a scheduling algorithm referred to as bag-of-tasks allocate-pull and divisible task allocation (BoTAPDTA) algorithm for handling hybrid tasks on heterogeneous distributed systems. In addition, to solving the optimization model efficiently, a generic algorithm(GA) is proposed. For the sake of reducing the search space and solving the optimization model effectively, a two step scheduling algorithm(TSGA), which first allocate bag-of-tasks(BoT) using generic algorithm and then assign divisible task to processors like BoTAPDTA, is designed. Finally, numerical simulation experiments are conducted, and experimental results indicate the effectiveness of the proposed model and algorithm.

Authors: Cichowicz Ewa , Rollnik-Sadowska Ewa
Published: September 2018

Referring to the concept of inclusive growth, the authors analyse the transition economies of the Central and Eastern European countries, which are the current EU members (Bulgaria, Croatia, the Czech Republic, Estonia, Latvia, Lithuania, Hungary, Poland, Romania, Slovakia and Slovenia). That region was selected as the CEE countries characterized by comparable historic and economic background but now they seem to reach diversified stages of development. The objective of the study is to identify the level of inclusive growth among the CEE countries, taking into account indicators assigned to its seven pillars. The thesis is that the CEE countries represent socio and economic heterogeneity as well as different levels of sustainable development. The research methods involved the application of the principal components analysis and the multivariate analysis. For literature review, the bibliometric analysis was conducted with the visualization prepared by the VOSviewer software. The main findings suggest that Estonia, Slovenia and the Czech Republic seem to be the ones with the highest inclusive growth. On the other hand, Bulgaria and Romania represent the lowest level of inclusive growth indicators.

Field and numerical investigations at Happisburgh, East coast of England, UK, sought to characterize beach thickness and determine geologic framework controls on coastal change. After a major failure of coastal protection infrastructure, removal of about 1 km of coastal defense along the otherwise protected cliffed coastline of Happisburgh triggered a period of rapid erosion over 20 years of ca. 140 m. Previous sensitivity studies suggested that that beach thickness plays a major role in coastal recession. These studies were limited, however, by a lack of beach volume data. In this study, we have integrated the insights gained from our understanding of the Quaternary geology of the area, a novel non-intrusive passive seismic survey method, and a 3D novel representation of the subsurface source and transportable material into a coastal modelling environment to explore the role of beach thickness on the back wearing and down wearing of the cliffs and consolidated platform, respectively. Results show that beach thickness is non-homogeneous along the study site: we estimate that the contribution to nearshore sediment budget via platform down wearing is of a similar order of magnitude as sediment lost from the beach and therefore non-negligible. We have provided a range of evidence to support the idea that the Happisburgh beach is a relatively thin layer perched on a sediment rich platform of sand and gravel. This conceptualization differs from previous publications, which assumes that the platform was mostly till and fine material. This has direct implication on the regional sediment management of along this coastline. The present study contributes to our understanding of a poorly known aspect of coastal sediment budgeting and outlines a quantitative approach that allows for simple integration of geological understanding for coastline evolution assessments worldwide.
Organogenesis: A New Theme to Study Genetic Expression in Adult Liver Regeneration After Partial Hepatectomy
Authors: Witwit Haydar
Published: September 2018

Researchers in different disciplines studied liver’s genetic expression of organogenesis in embryogenesis; however, organogenesis has not been studied as an independent and a complementary process during adult liver regeneration. This paper reviewed studies and extracted information related to organogenesis in adult liver regeneration because of organogenesis’ important role in cancer and tissue regeneration.
Economic Consequences of Cooling Water Insufficiency in the Thermal Power Sector under Climate Change Scenarios

Published: September 2018

Abstract: Currently, thermal power is the largest source of power in the world. Although the impacts of climate change on cooling water sufficiency in thermal power plants have been extensively assessed globally and regionally, their economic consequences have seldom been evaluated. In this study, the Asia-Pacific Integrated Model Computable General Equilibrium model (AIM/CGE) was used to evaluate the economic consequences of projected future cooling water insufficiency on a global basis, which was simulated using the H08 global hydrological model. This approach enabled us to investigate how the physical impacts of climate change on thermal power generation influence economic activities in regions and industrial sectors. To account for the uncertainty of climate change projections, five global climate models and two representative concentration pathways (RCPs 2.6 and 8.5) were used. The ensemble-mean results showed that the global gross domestic product (GDP) loss in 2070–2095 due to cooling water insufficiency in the thermal power sector was −0.21% (−0.12%) in RCP8.5 (RCP2.6). Among the five regions, the largest GDP loss of −0.57% (−0.27%) was observed in the Middle East and Africa. Medium-scale losses of −0.18% (−0.12%) and −0.14% (−0.12%) were found in OECD90 (the member countries of the Organization for Economic Co-operation and Development as of 1990) and Eastern Europe and the Former Soviet Union, respectively. The smallest losses of −0.05% (−0.06%) and −0.09% (−0.08%) were found in Latin America and Asia, respectively. The economic impact of cooling water insufficiency was non-negligible and should be considered as one of the threats induced by climate change.

Determination of time-weighted average (TWA) concentrations of volatile organic compounds (VOCs) in air using solid-phase microextraction (SPME) is advantageous over other sampling techniques, but is often characterized by insufficient accuracies, particularly at longer sampling times. Experimental investigation of this issue and disclosing the origin of the problem is problematic and often not practically feasible due to high uncertainties. This research is aimed at developing the model of TWA extraction process and optimization of TWA air sampling by SPME using finite element analysis software (COMSOL Multiphysics). It was established that sampling by porous SPME coatings with high affinity to analytes is affected by slow diffusion of analytes inside the coating, an increase of analytes concentrations in the air near the fiber tip due to equilibration, and eventual lower sampling rate. The increase of a fiber retraction depth (Z) resulted in better recoveries. Sampling of studied VOCs using 23-ga Car/PDMS assembly at maximum possible Z (40 mm) was proven to provide more accurate results. Alternative sampling configuration based on 78.5 x 0.75 mm i.d. SPME liner was proven to provide similar accuracy at improved detection limits. Its modification with the decreased internal diameter from the sampling side should provide even better recoveries. The developed model offers new insight into optimization of air and gas sampling using SPME.
Dual Quantum Mechanics and Its Electromagnetic Analog
Authors: Arbab Arbab
Published: September 2018

An eigenvalue equation representing symmetric (dual) quantum equation is introduced. The particle is described by two scalar wavefunctions, and two vector wavefunctions. The eigenfunction is found to satisfy the quantum Telegraph equation keeping the form of the particle fixed but decaying its amplitude. An analogy with Maxwellian equations is presented. Massive electromagnetic field will satisfy a quantum Telegraph equation instead of a pure wave equation. This equation resembles the motion of the electromagnetic field in a conducting medium. With a particular setting of the scalar and vector wavefunctions, the dual quantum equations are found to yield the quantized Maxwell's equations. The total energy of the particle is related to the phase velocity ($v_p$) of the wave representing it by $E=p\,|v_p|$, where $p$ is the matter wave momentum. A particular solution which describes the process under which the particle undergoes a creation and annihilation is derived. The force acting on the moving particle is expressed in a dual Lorentz-like form. If the particle moves like a fluid, a dissipative (drag) quantum force will arise.

Published: September 2018

Recent research has revealed surprisingly important connections between animals’ microbiome and social behaviour. Social interactions can affect the composition and function of the microbiome; conversely, the microbiome affects social communication by influencing the hosts’ central nervous system and peripheral chemical communication. These discoveries set the stage for novel research venues focusing on the evolution and physiology of animal social behaviour in relation to microbial transmission strategies. Here, we discuss the emerging roles of teleost fish model candidates and their key potential for advancing research fields linked to sociality and microbial regulation. We argue that fish models, such as the zebrafish, sticklebacks, guppies and cleaner-client dyads, will provide valuable insights into the roles of microbiome in shaping social behaviour and vice versa, while also being of direct relevance to the food and ornamental fish trades.
Control of a DC-DC Buck Converter through Contraction Techniques

Published: September 2018

Reliable and robust control of power converters is a key issue in the performance of numerous technological devices. In this paper we show a design technique for the control of a DC-DC buck converter with a switching technique that guarantees not only good performance but also global stability. We show that making use of the contraction theorem in the Jordan canonical form of the buck converter, it is possible to find a switching surface that guarantees stability but it is incapable of rejecting load perturbations. To overcome this, we expand the system to include the dynamics of the voltage error and we demonstrate that the same design procedure is not only able to stabilize the system to the desired operation point but also to reject load, input voltage and reference voltage perturbations.
Medium-Range Probabilistic Forecasts of Wind Power Generation and Ramps in Japan Based on a Hybrid Ensemble
Authors: Ohba Masamichi , Kadokura Shinji , Nohara Daisuke
Published: September 2018

 This study shows the application of self-organizing maps (SOMs) to probabilistic forecasts of wind power generation and ramps in Japan. SOMs are applied to atmospheric variables obtained from atmospheric reanalysis over the region, thus deriving classified weather patterns (WPs). Probabilistic relationships are established between the synoptic-scale atmospheric variables over East Japan and the generation of regionally integrated wind power in East Japan. Medium-range probabilistic wind power predictions are derived by SOM, as analog ensembles based on the WPs of the multi-center ensemble forecasts. As this analog approach handles stochastic uncertainties effectively, probabilistic wind power forecasts are rapidly generated from a very large number of forecast ensembles. The use of a multi-model ensemble provides better results than a one-forecast model. The hybrid ensemble forecasts further improve the probabilistic predictability skill of wind power generation, as compared with non-hybrid methods. It is expected that long-term wind forecasts will provide better guidance to transmission grid operators. The advantage of this method is that it can include an interpretative analysis of meteorological factors for variations in renewable energy.
