Published: February 2021

Abstract
Large data centre provides the important facilities like storage, computation, communication, etc. Therefore, we must be very careful while designing the infrastructure and networking of the data centre as these factors decides the expenses on implementation and maintenance of the infrastructure. The data servers are connected with Top of Rack (ToR) switches, which are further connected to aggregated/core switches. This paper discusses the blocking performance of the switches used at various levels of optical data networks. However it must be noted that in data centres traffic is not blocked and but it is temporarily stored but if it can’t stored a negative acknowledgement is sent back and packet re-transmission is done. Blocking performance is done to judge the re-transmission of packets. Blocking performance is obtained using mathematical model as well as using Monte Carlo Simulations.

Comparison of heat transfer in natural and forced circulation under rolling motion
Authors: Wang C. , Shi E. , Sun L. , Chen W. 
Published: February 2021

Abstract
A comparative analysis of heat transfer characteristic in pulsating flow induced by rolling motion under natural circulation and forced circulation condition was performed. Variation of local and average heat transfer characteristics with rolling motion were also investigated. The results show that the natural circulation time-averaged heat transfer characteristic is enhanced by rolling motion. However, the variation of time-averaged heat transfer characteristic of forced circulation is not significant. In addition, the relationship between the relative pulsation amplitude of Reynolds number and Nusselt number does not present predominant difference in natural and forced circulation conditions.

On certain Diophantine equations concerning the area of right triangles
Authors: Zhang Yong , Gao Dan 
Published: February 2021

Abstract
Using the theory of elliptic curve, we show that all right triangles, such that the sum of the area and the square of the sum of legs is a square, are given by an infinite set. Similarly, we get all right triangles such that the sum of the area and the square of the semi-perimeter is a square. Using the theory of Pell’s equation, we prove that there are infinitely many non-primitive right triangles such that the sum of the area and the hypotenuse (or the smaller leg) is a square, and an infinity of primitive right triangles such that the sum of the area and the smaller leg (or the perimeter, the semi-perimeter, the larger leg) is a square.

Recovery of heather (Calluna vulgaris) flowering in northern Finland
Authors: Manninen Outi , Peltola Rainer 
Published: February 2021

Abstract
Heather is a slow-growing evergreen shrub, commonly found in moorlands and heaths of high nature conservation value. Heather-dominated areas are used as livestock pasture, and the flowers of heather are harvested also for the natural product industry. Classical studies have focused on the recovery of shoot biomass of heather, while the recovery of flowering after grazing or harvesting has received less attention. In this study, we examined the recovery of heather flowering in one harvesting experiment and two observational areas in northern Finland. The flowers of heather were collected manually by clipping the flowering shoots or stripping the flowers from the shoots or by machine harvesting. We counted the number of short shoots (SS), nonflowering long shoots (NFLS), and flowering long shoots (FLS) after harvesting. We also measured the length of FLS and counted the flowers they produced. Heathers started to recover by producing new short shoots, while the recovery of flowering was slow, and only in one out of the three areas, flowering recovered totally during our study. Our results suggest that the recovery was dependent on the age of heather or individual site characteristics rather than on the harvesting method. Because flowering is one of the most important stages of successful reproduction, which affects the long-term existence of heather-dominated ecosystems, the results of our study can contribute to new guidelines for management practices in heathlands. However, longer-term experiments on the rate of flowering recovery are needed especially if rotational cutting is favored as a management practice in heathlands in the future.
From image to text to speech: the effects of speech prosody on information sequencing in audio description
Authors: Hirvonen Maija , Wiklund Mari 
Published: February 2021

Abstract
Given the extensive body of research in audio description – the verbal-vocal description of visual or audiovisual content for visually impaired audiences – it is striking how little attention has been paid thus far to the spoken dimension of audio description and its para-linguistic, prosodic aspects. This article complements the previous research into how audio description speech is received by the partially sighted audiences by analyzing how it is performed vocally. We study the audio description of pictorial art, and one aspect of prosody is examined in detail: pitch, and the segmentation of information in relation to it. We analyze this relation in a corpus of audio described pictorial art in Finnish by combining phonetic measurements of the pitch with discourse analysis of the information segmentation. Previous studies have already shown that a sentence-initial high pitch acts as a discourse-structuring device in interpreting. Our study shows that the same applies to audio description. In addition, our study suggests that there is a relationship between the scale in the rise of pitch and the scale of the topical transition. That is, when the topical transition is clear, the rise of pitch level between the beginnings of two consecutive spoken sentences is large. Analogically, when the topical transition is small, the change of the sentence-initial pitch level is also rather small.
Actividade Antioxidante en Carne de Tenreiros Alimentados con Bagazo de Uva
Authors: Rubio Laura , Lamas Juan Pablo , García-Jares Carmen , Lores Marta 
Published: February 2021

Os subprodutos de elaboración do viño conteñen valiosos compostos bioactivos, entre os que destacan os polifenois. Os efectos beneficiosos destes compostos atribúense, entre outras, á súa actividade antioxidante. Por esta razón, estúdase o efecto potencial dunha dieta enriquecida en polifenois nas características da carne de tenreiros alimentados con bagazo de uva como complemento ou suplemento na súa alimentación. Proponse unha extracción rápida de seis polifenois individuais de carne crúa de tenreiro, previamente identificados e seleccionados como marcadores no bagazo. O procedemento baséase na extracción simultánea automatizada mediante líquidos presurizados (PLE) seguida de cromatografía líquida de alta eficacia con detección UV-Vis cun sistema de díodos (HPLC-DAD) para a identificación dos polifenois e a análise cuantitativo. Nos extractos obtidos determínanse o índice de polifenois totais (IPT) e a actividade antioxidante (AA). Debido á complexidade da mostra, os resultados máis sobresaíntes deste traballo son os relacionados coa avaliación da actividade antioxidante dos extractos. Tras a correspondente análise estatística do conxunto de datos obtidos, pode observarse que resulta mellor incluír unha combinación de bagazo na dieta dos animais dada a mellora observada nos índices antioxidantes medidos, e en consecuencia, tamén nas propiedades da carne e na súa conservación.
ДИСИДЕНТСЬКА ДІЯЛЬНІСТЬ ОПАНАСА ЗАЛИВАХИ (1960–1970 ті рр.)
Authors: Паска Богдан 
Published: February 2021

Предметом статті є основні віхи, напрями і етапи участі художника Опанаса Івановича Заливахи в українському національному русі 1960–1970-х рр. Основу джерельної бази дослідження становлять документи Галузевого державного архіву Служби безпеки України (ГДА СБУ) у м. Київ, матеріали самвидаву, спогади самого О. Заливахи та його сучасників. Методологічною основою дослідження є концепція Я. Секо про співіснування в українському русі спротиву 1950–80‑х рр. двох парадигм – національно-визвольної (підпільні організації) та націоналізаційної (легальна діяльність інтелігенції із середовища “шістдесятників”). Автор статті приходить до висновку, що художник О. Заливаха з початку 1960‑х до першої половини 1970‑х був активним учасником середовища шіст­десятницького правозахисту в рамках націоналізаційної парадигми українського національного руху. У першій половині 1960‑х рр. основними формами його дисидентської діяльності були поширення сам­видаву і тамвидаву, критика політики радянської влади у національному питанні, виготовлення україн­ської національної символіки. Арешт та судова розправа над О. Заливахою не змогли зупинити його дисидентської діяльності та не змінили опозиційних щодо офіційної політики радянського режиму переконань. У мордовських колоніях художник брав участь в українських культурних заходах, налаго­джував канали передачі документів і матеріалів із колонії на волю, написав заяву протесту на адресу Голови Верховного Суду УРСР. Після виходу на волю найбільш помітною дисидентською акцією ху­дожника була його участь у кампанії захисту засудженого історика В. Мороза. В подальшому О. Зали­ваха, незважаючи на те, що був взятий КДБ у розробку як об’єкт справи “Блок”, під тиском режиму практично повністю припинив активність у руслі руху спротиву радянському режиму.

“EX PAGANIS CHRISTIANOS ESSE PATRAVIT”: КОГО ВІДПРАВИВСЯ ХРИСТИЯНІЗУВАТИ НІТРАНСЬКИЙ ЄПИСКОП ВІХІНГ?
Authors: Кардаш Остап 
Published: February 2021

Стаття присвячена проблемі визначення географічних меж місіонерської діяльності нітран­сь­кого єпископа Віхінга після його висвячення у Римі папою Іоаном VIII у 880 р. Шляхом перехресного ана­лізу агіографічних текстів, епістолярних джерел та інших наративів кінця ІХ – першої половини Х ст., а також окремих археологічних пам’яток автор намагається реконструювати харатер церковно-по­літичних взаємин держави великоморавського князя Святоплука останньої чверті ІХ ст. із сусідніми gentes і визначити, ким був згаданий у листі баварського єпископату до папи Іоана ІХ “neophita gens”, до котрого, з волі Святоплука та папи Іоана VIII, відправився з місією нововисвячений єпископ Віхінг. Не­зва­жаючи на те, що населення новозавойованих чи інкорпорованих великоморавським князем територій не завжди було язичницьким чи неофітським, експансійна політика Святоплука зазначеного періоду пе­ре­важно супроводжувалася християнізаційними, або ж євангелізаційними місіями духівницт­ва з мо­рав­сь­кого архієпископства Мефодія та його суфраганів, одним з яких і був нітранський єпископ Віхінг. Автор приходить до висновку, що місія останнього у перші роки після отримання єпископського сану у Римі у 880 р. скеровувалася на землі Потисся, завойованого Святоплуком близько 881/882 р. і цілком вписувалася у контекст експансійної політики правителя Великої Моравії.

Time to First Onset of Chest Binding–Related Symptoms in Transgender Youth
Authors: Peitzmeier Sarah M. , Silberholz John , Gardner Ivy H. , Weinand Jamie , Acevedo Kimberlynn 
Published: February 2021

BACKGROUND AND OBJECTIVES:Most transgender individuals assigned female at birth use chest binding (ie, wearing a tight garment to flatten chest tissue for the purpose of gender expression), often beginning in adolescence, to explore their gender identity. Although binding is often critical for mental health, negative physical side effects, ranging from chronic pain to rib fractures, are common. Time to first onset of symptoms is unknown.METHODS:A community-engaged, online, cross-sectional survey (“The Binding Health Project”) enrolled 1800 assigned female at birth or intersex individuals who had ever used chest binding. Lifetime prevalence of 27 pain, musculoskeletal, neurologic, gastrointestinal, generalized, respiratory, and skin or soft tissue symptoms related to binding was assessed. Nonparametric likelihood estimation methods were used to estimate survival curves.RESULTS:More than one-half (56%) of participants had begun binding by age 21, and 30% had begun by age 18. In 18 of 27 symptoms, the majority of people who go on to experience the event will do so within the first binding-year, but several skin-related and rare but serious outcomes (eg, rib fracture) took longer to occur. Pain presents rapidly but continues to rise in intensity over time, peaking at &gt;5 years of binding.CONCLUSIONS:Although many symptoms emerge quickly, others can take years to develop. Individuals and their clinicians can use this information to make informed decisions on how to structure binding practices and top surgery timing while meeting goals related to gender expression and mental health. Access to puberty blockers may delay initiation of binding, preventing binding-related symptoms in youth.
Industrial Hip Hop against the Hip Hop Industry
Authors: Kim Pil Ho , Lee Wonseok 
Published: February 2021

Since its humble beginnings about three decades ago, South Korea’s national hip hop scene (gukhip) has grown to a formidable industry that runs the gamut from cutting-edge underground artists to mainstream K-pop idol rappers. In recent years, the cable TV audition programme Show Me the Money (SMTM) has become the gukhip industry’s ultimate gatekeeper as many aspiring hip hop artists increasingly depend on making it on the show to advance their careers. In this article, we focus on XXX, an underground hip hop duo who bucks this commercial trend of gukhip in both sound and message. Their noise-filled beats and shifting grooves echo the avant garde aesthetics and confrontational attitudes of industrial music, and their words are harshly critical of the money-driven gukhip culture as represented by SMTM. We provide a musicological analysis of XXX’s own version of industrial hip hop and examine what makes their “outsider” status sustainable vis-à-vis the gukhip industry.
INCLUSÃO PELO TRABALHO FORMAL NO CONTEXTO DA SAÚDE MENTAL NO MUNICÍPIO DE PORTO ALEGRE/RS PELA PERSPECTIVA DA TERAPIA OCUPACIONAL
Authors: Reinheimer Rafaela Peixoto , Da Silva Clemildo Anacleto 
Published: February 2021

RESUMO O presente estudo teve como objetivo conhecer e investigar o processo de inclusão de pessoas com transtorno mental grave no mercado de trabalho formal no município de Porto Alegre/RS. Para tanto, foram realizadas entrevistas semiestruturadas individuais com cinco terapeutas ocupacionais que trabalham ou que já trabalharam com a inclusão de pessoas com diagnóstico de transtorno mental grave e persistente no mercado de trabalho formal na cidade de Porto Alegre/RS. As entrevistas foram analisadas conforme a técnica de análise de conteúdo proposta por Bardin. Os resultados alcançados revelam que o processo de inclusão é complexo e exige a participação e o comprometimento de todos. Diferentes empresas estão contratando este público que tem ocupado variados postos de trabalho e demonstrado bons resultados, progredindo e adquirindo estabilidade nos seus locais de trabalho. Como pontos positivos para esse processo, destaca-se os apoios e suportes disponibilizados pelas empresas e pelos terapeutas ocupacionais que tornam possível a inclusão. Algumas das dificuldades elencadas dizem respeito à presença de barreiras atitudinais, metodológicas, responsabilização da família e à existência de empresas pouco comprometidas com a inclusão. Podemos perceber a efetividade das práticas e processos de inclusão das pessoas com transtorno mental grave no mercado de trabalho formal, entretanto, é preciso que estas práticas tenham continuidade e que novas experiências despontem.
