ANALYSIS OF THE INFLUENCE OF AIR TEMPERATURE ON CHANGES IN GIBBS ENERGY IN THE FORMATION OF NITROGEN OXIDES IN SMOKE GASES OF BOILER PLANTS
Authors: BALANDINA Olga A. , PURUNG Svetlana M. , PASHCHENKO Dmitry I.
Published: May 2020

The article discusses the mechanisms of the occurrence of nitrogen oxides in the gas emissions of boiler plants. Using thermodynamic calculations, the probability and direction of the process of the formation of nitrogen oxides in the temperature range from 25 to 2000° C were determined. The geometric thermodynamics methods show changes in the Gibbs energy of reactions of the formation of nitrogen oxides from temperature, and determine the conditions for achieving their chemical equilibrium. An analysis of the results showed that the standard changes in the free energies (Gibbs energies) of the reactions of the formation of nitrogen oxides during the combustion of gas fuels are mostly negative
INFLUENCE OF GAP SEALS OBLITERATION OF PLUNGER COUPLES ON THE WORK OF ELECTRICITY SYSTEM DRIVES
Authors: KRESTIN Evgeny A. , SEREBRYAKOV Grigoriy V.
Published: May 2020

The influence of obliteration of slott ed gaps of plunger couples at the stage of design and calculation of drive systems for aggregates of electric power systems is considered. Obliteration is considered as a harmful phenomenon, on the basis of this, it is necessary to search for methods and means that contribute to the stabilization of flow. Such a problem arises whenever it is necessary to obtain small and stable over time fluid flow rates. Since obliteration is always accompanied by an increase in the forces required to move the mating parts relative to each other, for example, a plunger in a sleeve, ignoring this phenomenon can lead to underestimated costs of leakage of the working fluid. These efforts are all the more, the more active is the obliteration process. The analysis of experimental studies for various types of liquids with different gaps and pulsations of the pressure drop at the ends of the gap. The obliteration process, caused by the adsorption of liquid molecules, was approximated by an exponential function that allows you to determine the maximum possible thickness of the boundary layer of liquid formed on the channel wall.

Published: May 2020

The study of full-scale samples of bent reinforced concrete beams using tensioned ropes in a synthetic shell filled with grease is considered in the article. The purpose of the research is to test reinforced concrete beams using post-tensioned ropes to assess the load-bearing capacity and stiffness. Experimental results of studies on bent samples with rope tension and without ropes are presented. The study on full-scale samples revealed a number of features of the work of bent beams with post-tensioned ropes. The use of a post-tensioned rope without coupling with concrete allows for a more evenly distributed development of normal cracks and reduces the width of the crack opening. Pre-tension cable reinforcement increases the load carrying capacity of the area of the transverse bend.
RESEARCH OF HEAT DISPOSAL EFFICIENCY IN RECUPERATIVE HEAT EXCHANGERS OF AUTONOMOUS VENTILATION UNITS
Authors: KOSTUGANOV Arman B.
Published: May 2020

Full-scale tests of recuperative heat exchangers of autonomous ventilation units of a new design were carried out in order to determine the efficiency of heat recovery in them. As a result of the tests, it was found that the efficiency of heat recovery in such recuperative heat exchangers varies from 40 to 70 %, depending on the initial parameters of the supply and exhaust air. It was also found that in order to achieve the same heat recovery effect, it is advisable to use the construction of heat exchangers with corrugated mesh than the construction with corrugated plates because the first construction with a comparable heat recovery effect provides up to one and a half times lower aerodynamic drag. During the tests was also made an approbation of a new protection scheme for recuperative heat exchangers against freezing.

Is the End of Television Coming to an End?
Authors: Bourdon Jérôme
Published: May 2020

This article analyses the discourses of the end of television in relation to its status as a bad object. It traces the early, transnational, massive negative treatments of television. It suggests four explanations for this: sociological (television as a popular medium), economical (disappointing investment), metapsychological (frustrating experience), technological (insincere dispositif). It suggests that discourses of the end are coming to an end, because television is becoming a kind of archive, increasingly considered nostalgically, while its ‘quality series’ are achieving canonical aesthetic status. Finally, it suggests that discourses of the ends are organized into systems of interdependent ‘good’ and ‘bad’ media.
A comparative study of the effect of induction of labour with vaginal misoprostol versus prostaglandin E2 gel on the incidence of pathological cardiotocography tracing
Authors: Kumari Archana , Chauhan Nikita , Vidyarthi Anubha
Published: May 2020

Background: The objective of the present study was to compare the two most commonly used agents for induction of labor-vaginal misoprostol and intracervical dinoprostone gel in terms of the incidence of cardiotocography (CTG) abnormalities and its correlation with fetal distress and fetomaternal outcome.Methods: This is prospective case-control study conducted in department of obstetrics and gynecology, RIMS, Ranchi over a period of 15 months. 112 women requiring induction were randomly assigned to two groups of 56 each, Group M received vaginal misoprostol and Group D received intracervical dinoprostone E2 gel. 56 women with spontaneous labor served as control group. Groups were compared in terms of the incidence of suspicious or pathological CTG tracings, fetal distress, induction to vaginal delivery time, vaginal delivery rates, dose requirements, rate of emergency cesarean.Results: Misoprostol was associated with shorter induction to delivery time (9.54 hours) than dinoprostone gel (13.54 hours), higher vaginal delivery rates (80.35% versus 62.5%), higher delivery rates (73.9%) with single dose itself unlike Group D, where 47.22% required more than one dose. Incidence of suspicious CTG was higher in group M (15.68%) versus 10.25% in Group D. Incidence of pathological CTG was also highest in Group M (7.8%) followed by Group D (2.56%) and Group C (7.8%). Dinoprostone gel lead to failed induction in 25% women, and hence higher caesarean rates.Conclusions: While misoprostol is a better agent for induction when compared with dinoprostone E2 gel in terms of induction-delivery time, higher vaginal delivery rates, less dose requirement, it is associated with greater incidence of non-reassuring/pathological CTG. There was justified improvement in perinatal outcome due to preparedness beforehand with use of CTG.
Incidence of central venous and Foley’s catheter related bacteraemia, organisms responsible and antibiotic sensitivity pattern: in cardio-thoracic intensive theraputic unit following elective surgery, in a tertiary care hospital of Kolkata, India
Authors: Datta Swarnendu , Chakrabarty Ushnish , Chakrabarty Priyanka , Mukherjee Plaban
Published: May 2020

Background: Mortality from bacteraemia related to indwelling Central Venous Pressure (CVP) lines could be as high as 12 - 25% and that due to indwelling urinary catheters about 5%, in critically ill patients. Hence, initiation of early and aggressive antibiotic therapy, often even before the culture- sensitivity reports are available is necessary. Objectives of the study was to find out the incidence of bacteraemia  related to indwelling CVP catheters &/or Foley’s catheters in post operative patients in Cardio-thoracic  Intensive Theraputic Unit (ITU) and to understand the antibiotic sensitivity patterns against the organisms causing such bacteraemiaMethods: 48 hours after their insertion, CVP catheter tips, Foley’s catheter tips and Peripheral blood samples were collected for cultures in 50 patients who underwent elective cardiothoracic surgery, over a period of one year and results were interpreted.Results: Incidence of bacteraemia associated with indwelling CVP catheters was 8% and was caused by both - Gram positive (Staphylococcus aureus, Enterococcus faecium) and Gram negative (Acinetobacter baumanii, Pseudomonas aeruginosa) organisms. Foley’s catheter was not related to such blood stream infection.  Vancomycin and Linezolid were effective against the Gram positive organisms; while Piperacillin- Tazobactam, Meropenem, Polymyxin B and Colistin were effective against the Gram negative organisms.Conclusions: Indwelling CVP catheters were associated with blood stream infection in 4 post operative patients in our ITU. An idea about the organisms responsible, as well as their antibiogram may help in early initiation of antibiotics empirically before culture-sensitivity reports are available.

Authors: Yassin Maged M , Al-Najjar Mohammed S ,   Faculty of Medicine, Islamic University of Gaza, Gaza Strip, Palestine.,   Faculty of Science, Islamic University of Gaza, Gaza Strip, Palestine.
Published: May 2020

Toxicity studies of methamidophos on the physiological aspects of mammalian organs are limited in the literature. This study aimed to assess hepatic and renal functions in response to a sublethal dose of methamidophos in male domestic rabbits. A daily dose of 1/10 LD50 methamidophos was given orally to rabbits for 6 weeks. Control animals were given distilled water. Blood samples were collected and analyzed weekly. Serum glucose and bilirubin were increased upon methamidophos intake versus control, with the significant change commenced from the second and fifth weeks, respectively. In general, alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transferase, and alkaline phosphatase showed significant elevation throughout the whole experiment. Conversely, cholinesterase was significantly inhibited all over the experimental intervals studied. Serum urea and creatinine showed a significant increase whereas total protein, albumin, and globulin exhibited a significant decrease during the last five weeks of the experiment. Hypocalcemia and hyperphosphatemia were also observed in methamidophostreated rabbits. Methamidophos exposure at a sublethal dose had a potential toxic effect on liver and kidney functions as indicated by significant alterations in their biomarkers. Such findings can then be extrapolated to human beings to assess the potential hazards in human populations due to methamidophos exposure.

Published: May 2020

Bu çalışmanın amacı, alan yazında kimlik olgusunun gelişimi ve buna dair kuramların kimlik olgusundaki rolünü incelemektir. Erikson’un psikososyal kimlik kuramında, bireylerin biyolojik-bireysel-sosyal yönlerindeki değişkenlerin onların ego kimliği oluşturmalarında son derece önemli olduğu vurgulanmaktadır. Erikson’dan sonra gelen ve onun fikirlerinden etkilenen kuramcıların ise kimliği çalışırken daha çok kimliğin bir yönünü merkeze aldıkları görülmüştür. Gelişim psikolojisi literatüründe daha çok kimlik oluşumunda bireysel-içsel faktör merkezli kuramlar ortaya konulmuştur. Son 30 yıllık zaman diliminde ise anlatı kuramcılarının kimlik oluşumunu ve gelişimini çalışarak Erikson’un kuramını bütüncül bir şekilde ele aldıkları görülmektedir. Anlatı kimlik formunda bireyler geçmişlerindeki deneyimlerden yola çıkarak bir hikaye formu oluşturmakta ve oluşturdukları bu hikaye formuna göre yaşayıp bir kimlik var etmektedirler. Bireyler anlatılar aracılığıyla kimliklerine dair tüm değişkenleri hikayeleştirerek anlattıklarından dolayı kimlik oluşumlarındaki tüm değişkenlerin ilişkisini ifade etme şansı bulmaktadırlar. Anlatı kuramcıları kimlik oluşumunda; öz hikayelerin, kuşaklararası hikayelerin, ana anlatıların, tarihsel ve sosyal olayların kimliği şekillendirdiğini ortaya koymaya çalışmıştır.

Authors: Hamaoka Kodai , Watanabe Kota , Kamiya Tomoaki , Teramoto Atsushi , Yamashita Toshihiko
Published: May 2020

Case:

Nontraumatic chronic subcutaneous rupture of the extensor digitorum longus (EDL) tendon is rare. A 66-year-old man, recreational runner, suddenly injured his EDL tendon while walking. We surgically reconstructed the ruptured EDL tendon with a free palmaris longus tendon graft. During the surgery, an osteophyte was found to have penetrated the ankle joint capsule and was considered the cause of the tendon rupture. Active toe extension was restored, and the patient completed a 10-km race at 2 months postoperatively.

Conclusion:

EDL tendon reconstruction using a free palmaris longus tendon graft is an effective surgical option for athletes.

Authors: Lalchandani Gopal R. , Chan Alvin , Nagao Masato , Immerman Igor
Published: May 2020

Case:

A 63-year-old woman with a history of a malunited distal radius fracture presented with left hand pain and inability to flex her thumb, index, and middle fingers. Anterior interosseous neuropathy was suggested because of abnormal electromyography findings. However, magnetic resonance imaging later revealed flexor tendon ruptures. A distal radius corrective osteotomy with autograft and volar fixation was performed with tendon transfers and carpal tunnel release.

Conclusions:

Attritional flexor tendon rupture after a nonoperatively managed distal radius fracture is rare but remains an important differential diagnosis in patients with signs and symptoms of anterior interosseous nerve paralysis.

Published: May 2020

Over the past decade, our increased understanding of the interactions between the immune
system and cancer cells has led to paradigm shifts in the clinical management of solid and hematologic
malignancies. The incorporation of immune-targeted strategies into the treatment landscape
of acute myeloid leukemia (AML), however, has been challenging. While this is in part due to
the inability of the immune system to mount an effective tumor-specific immunogenic response
against the heterogeneous nature of AML, the decreased immunogenicity of AML cells also represents
a major obstacle in the effort to design effective immunotherapeutic strategies. In fact, AML
cells have been shown to employ sophisticated escape mechanisms to evade elimination, such as direct
immunosuppression of natural killer cells and decreased surface receptor expression leading to
impaired recognition by the immune system. Yet, cellular and humoral immune reactions against
tumor-associated antigens (TAA) of acute leukemia cells have been reported and the success of allogeneic
stem cell transplantation and monoclonal antibodies in the treatment of AML clearly provides
proof that an immunotherapeutic approach is feasible in the management of this disease. This review
discusses the recent progress and persisting challenges in cellular immunotherapy for patients with
AML.
Representações sociais de praticantes de religião de matriz africana sobre a laicidade
Authors: Freire Phablo , Gonzaga Murilo Amador
Published: May 2020

O trabalho objetiva discutir como as representações sociais dos indivíduos praticantes de religiões de matriz africana sobre os três pressupostos da laicidade afetam sua constituição identitária. A pesquisa qualitativa empírica descritiva de natureza interdisciplinar utilizou para coleta de dados entrevistas semiestruturadas e análise de conteúdo com suporte do software Iramuteq. Para controle dos dados e conclusões auferidas adotou-se o método de triangulação pelo cruzamento de três eixos, sendo eles: 1. as teorias do constitucionalismo-legislação simbólica, das identidades e representações sociais, 2. o arcabouço jurídico-normativo que disciplina a laicidade e, 3. as representações sociais dos sujeitos acerca do fenômeno. Concluiu-se que as representações sociais apontam para um quadro de violação dos três pressupostos da laicidade, qualificando-a como prescrição jurídica esvaída de normatividade e portanto simbólica, nas modalidades legislação-confirmação de valores, legislação-formula de compromisso dilatório e legislação-álibi. Oferecendo óbice a concretização das expectativas normativas de igualdade nas interações sociais atravessadas pelo elemento religioso e determinando a elaboração identitária dos indivíduos e grupos sociais.
O Supremo Tribunal Federal pretende assumir poderes de um típico órgão de política tributária?
Authors: Seabra de Godoi Marciano , Freitas Júnior Efigênio
Published: May 2020

O artigo tem por problema/objeto de pesquisa a possível determinação do Supremo Tribunal Federal (STF) de exercitar – por vias indiretas – papéis típicos de um órgão de política tributária. A metodologia do artigo consiste na análise de um precedente recente do STF (RE 723.651) acerca da constitucionalidade da incidência do imposto sobre produtos industrializados sobre operações de importação de equipamentos para uso próprio por pessoas que não desempenham atividades industriais (tais como indivíduos, hospitais etc.). Analisam-se as posições, observações e fundamentações dos votos dos ministros que participaram do julgamento, de modo a verificar se o tribunal fixou seu precedente jurisprudencial de modo juridicamente coerente e se tem consciência de que pode estar avançando indevidamente sobre um campo de atuação estranho a suas atribuições e habilidades institucionais (ativismo judicial). O resultado do estudo apontou que, pelo menos no caso do julgamento analisado, o STF se mostra consciente dos riscos de sua atuação avançar sobre competências de outros poderes e tem uma compreensão equivocada sobre o que é o minimalismo judicial; insistindo numa aplicação errônea deste conceito, a Corte tende a agir como um órgão formulador de política tributária.
Критические моменты послеоперационного периода, постдекомпрессионная дисфункция печени в хирургии неопухолевой обтурационной желтухи
Authors: Savoliuk S.I.
Published: May 2020

Актуальность. Современные теории патогенеза пост­декомпрессионных дисфункций печени (ПДДП) пытаются акцентировать внимание на отдельной патофизиологической стороне сложного процесса и механизма инициации. Однако только комплексный подход позволяет объективно определять механизмы развития дисфункций печени в послеоперационном периоде. Цель исследования: определение особенностей и закономерностей влияния традиционных и малоинвазивных методов билиарной декомпрессии на функциональное состояние печени относительно ПДДП у больных с обтурационной желтухой неопухолевой этиологии (ОЖНОЭ). Материалы и методы. Проанализированы результаты хирургического лечения 510 больных с неопухолевой обтурационной желтухой. Результаты. Ранжирование больных по способу и методам билиарной декомпрессии дало возможность определить влияние метода хирургического лечения на степень печеночной дисфункции в послеоперационном периоде путем регистрации динамики ее прогностических предикторов, что позволило оценить степень послеоперационной безопасности традиционных и малоинвазивных методов наружной и внутренней билиарной декомпрессии относительно прогрессирования постдекомпрессионной дисфункции печени. Выводы. Разработка подходов к дифференцированному выбору хирургической тактики и методов ее реализации с позиции степени послеоперационной безопасности методов хирургической интервенции и постдекомпрессионного усугубления имеющейся печеночной дисфункции привело к перераспределению структуры выполненных оперативных вмешательств у больных ОЖНОЭ в пользу малоинвазивной коррекции, создание обоснованных протоколов периоперационного сопровождения способствовало уменьшению послеоперационных осложнений на 10,26 % (с 16,87 до 6,61 %), ПДДП — на 9,19 % (с 10,84 до 1,65 %) и летального исхода — на 6,4 % (с 7,23 до 0,83 %).
Особенности обмена глюкозы у школьников с бронхиальной астмой, получающих базисную противовоспалительную терапию ингаляционными глюкокортикостероидами
Authors: Buryniuk-Glovyak K.P. , Koloskova О.К.
Published: May 2020

Актуальность. Ингаляционным глюкокортикостероидным препаратам принадлежит ведущая роль в профилактическом лечении бронхиальной астмы (БА) на этапе достижения и в дальнейшем — для поддержания контроля над клиническими симптомами заболевания. Несмотря на достаточную безопасность, данная группа лекарственных средств также не лишена побочных эффектов, причем особую остроту этот вопрос приобретает при длительных курсах высокодозного лечения у детей дошкольного и школьного возраста. Цель работы: изучить особенности обмена глюкозы у детей, больных бронхиальной астмой, на фоне использования ингаляционных глюкокортикостероидов для оптимизации лечебно-профилактических мероприятий и менеджмента заболевания. Материалы и методы. Для достижения цели исследования методом случайной выборки проведено определение уровня гликемии натощак 74 госпитализированным по поводу обострения БА детям школьного возраста. Исходя из полученных результатов, детей распределяли на две клинические группы сравнения в зависимости от уровня гликемии, который или превышал значение 5,5 ммоль/л (37 детей), или не достигал 5,5 ммоль/л (37 детей). Результаты. Наличие признаков нарушения физического развития со склонностью к избыточной массе тела у детей обеих клинических групп сравнения могло способствовать нарушению толерантности к глюкозе. У детей I группы среднее содержание глюкозы в крови через 2 часа после приема пищи составило 6,43 ± 0,28 ммоль/л (минимально — 4,8 ммоль/л, максимально — 9,5 ммоль/л). В группе сравнения эти результаты составили 5,49 ± 0,11 ммоль/л (4,4–7,7 ммоль/л) (P < 0,05), что свидетельствовало о наличии нарушения толерантности к глюкозе преимущественно среди представителей І клинической группы. Следует отметить, что в I группе вдвое большей оказалась часть больных, у которых через 2 часа после приема пищи уровень гликемии не возвратился к нормальным значениям (86,67 % детей), а в группе сравнения — в 40 % случаев (P < 0,01). Выводы. Гипергликемия натощак у больных бронхиальной астмой школьников ассоциирует с увеличением относительно нормы массы тела у каждого четвертого пациента, что вдвое больше, чем у детей с нормогликемией, а также у этих больных через 2 часа в 86,67 % случаев не происходит нормализации уровня глюкозы
Основные и плейотропные эффекты витамина D у пациентов с сахарным диабетом 1-го и 2-го типа
Authors: Pankiv I.V.
Published: May 2020

Витамин D, будучи исходно биологически неактивным, превращается в организме в активную форму, взаимодействующую с ядерными рецепторами многих тканей и органов. Вследствие этого сего­дня витамин D признан D-гормоном, хотя, следуя исторической традиции, его продолжают называть витамином. Основная роль витамина D сводится к регуляции кальциевого гомеостаза, что во многом связано с влиянием на кишечную абсорбцию ионов кальция и ремоделированием (формированием и резорбцией) костей. Однако в последние десятилетия было выявлено еще по крайней мере 5 областей физиологии, в которых витамин D уверенно проявляет свои функции: врожденный иммунитет; адаптивный иммунитет; секреция инсулина β-клетками и другие аспекты поддержания гомеостаза глюкозы; работа сердца и регуляция артериального давления; развитие мозга и плода. Наша статья посвящена третьей из перечисленных областей — применению витамина D для профилактики и лечения сахарного диабета 1-го и 2-го типа (СД1 и СД2). В экспериментальных исследованиях было продемонстрировано, что витамин D важен для адекватной секреции инсулина и нормализации уровня глюкозы в плазме крови. В клинических работах была установлена взаимосвязь между низким уровнем витамина D в сыворотке крови и риском развития обоих типов сахарного диабета. Показана эффективность витамина D в профилактике и лечении сахарного диабета. Важное значение имеет тот факт, что витамин D проявляет дополнительные плейотропные эффекты, выявленные у пациентов с СД2: нормализует артериальное давление, липиды крови, индекс массы тела, борется с хроническим воспалением, препятствует развитию ретинопатии и диабетической периферической нейропатии. Назначение витамина в больших дозах (2000–4000 МЕ/день или больше) приводит к развитию желаемого эффекта в краткосрочных режимах терапии (3–6 месяцев). Если врач имеет дело с СД1, должны использоваться такие же большие дозы витамина.
A Review of the High-speed Permanent Magnet Rotor Stress Analysis used for Automotive Air-handling Machines
Authors: Mallin Levi Ryan , Barrans Simon Mark
Published: May 2020

Machines incorporating high-speed electrical machines (HSEM) are becoming increasingly common place in applications including air handling, energy storage and medical devices. They are of increasing interest within the automotive field for air handling applications. HSEM’s use surface-mounted permanent magnet (PM) rotors, manufactured from rare earth metals. However, these PM’s have low tensile strength and are susceptible to failure under the centrifugal load produced at high speed rotation. Retaining sleeves which are an interference fit around the magnets, provide compression and hence resistance to tensile stress. The ability to predict the stresses within the rotor assembly is essential for robust design. This review paper examines existing analytical calculations and finite element analysis (FEA) models. The analytical approaches include both plane stress and plane strain models and the limitations of these are discussed. For relatively long rotors, a generalised plane strain approach is suitable, however it is seldom used. In addition, this latter approach has not been extended to assemblies where the magnets are assembled onto a carrier or shaft. Optimisation of rotors has been addressed in a relatively small number of papers. However, further work is required in this area to ensure that the optimised rotors can be manufactured.
Analysis of Hydrate Formation Temperature and Water Dew Point of Processed Crude Oil and Gas using Unism Simulator
Authors: Amadi Azubuike Hope , Okafor Chukwuebuka E.
Published: May 2020

Flow assurance has been a topic of concern since the start of crude oil and gas production and transportation. The formation of Hydrates is an important issue likely to cause clogs in pipelines during production and transportation of oil and gas. Therefore, production and transportation of such fluids are simulated using software’s like Unism to know the possibility of hydrate occurrence so they can be avoided. This work is based on the simulation of processed well effluents from Rose Field to analyze the hydrate formation temperature and water dew point at different points of the process facility. At the crude oil line the hydrate formation temperature was -69.9565 C, while the water dew point was not defined because it’s a liquid phase. At the gas line the hydrate formation temperature was 4 C at 1803psia and water dew point was -42.7 C. These values are parameters necessary for hydrate formation prediction, hence, they were analyzed and recommendations made to manage effective flow assurance.

Published: May 2020

Head and neck cancers (HNC) are indicated when cells grow abnormally.  The disturbing rate of morbidity and mortality of patients with HNC due to late presentation is on the increase especially in Africa (developing countries). There is need to diagnose head and neck cancer early if patients present so that prompt referral could be facilitated.  The collected data consists of 1473 instances with 18 features. The dataset was divided into training and test data.  Two supervised learning algorithms were deployed for the study namely: Decision Tree (C4.5) and k-Nearest Neighbors (KNN). It showed that Decision Tree outperformed with accuracy of 91.40% while KNN had accuracy of 88.24%. Hence, machine learning algorithm like Decision Tree can be used for diagnosis of HNC in healthcare organisations.

Published: May 2020

Brain Tumor is a dangerous disease. The chance of the death is more in case of the brain tumor. The method of detection and classification of brain tumor is by human intervention with use of medical resonant brain images. MR Images may contain noise or blur caused by MRI operator performance which can lead to difficult in classification. We can apply effective segmentation techniques to partition the image and apply the classification technique. Support Vector machine is the best classification tool we identified as part of this work.  The use Support Vector Machine show great potential in this field. SVM is a binary Classifier based on supervised learning which gives better result than other classifiers. SVM classifies between two classes by constructing hyper plane in high-dimensional feature space which can be used for classification.
Towards Sustainable Composite Building Material: Integrating Lime with Slag for reduced mortar Thermal Conductivity
Authors: Olaniyan Sule Adeniyi
Published: May 2020

Lime Based Mortar became very popular due to its outstanding features of flexibility, permeability and low carbon emissions. However, lime’s characteristic delayed setting, late hardening time, low mechanical strength, among others, overshadowed significance of its outstanding features, thereby putting its overall use into decline, particularly, with the 19th century Portland Cement discovery. This study therefore aims at reviving lime usage through a sustainable lime composite, by integrating an industrial by-product, Ground Granulated Blast Furnace Slag (slag) with lime, in form of lime-slag mortar, with a view to reducing the mortar thermal conductivity. The methodology involved mortars with the same Binder/Aggregate (B/A) mix ratio (1:3) using five separate volumetric compositions of ‘slag-lime’ binders (i.e. 1:1, 1:2, 1:3, 2:1 and 3:1). Physical properties of the mortars involving their Water/Binder (W/B) ratios, Air Contents and Bulk Densities were recorded. Comparative evaluations of the compositions in hardened state, involving thermal conductivities were carried out at specific intervals through a twelve-month curing period. These were partly monitored through assessments of the composites’ microstructural behaviours over a six-month period. Results of the investigation show that addition of slag to mortars facilitate slightly larger pores with increased porosities. However, these effects are minimal (i.e. from 23.42% to 25.37% porosity) when slag content is at equal volumetric content with lime. A general reduction (not in a linear trend) in the thermal conductivities of the mortar with increasing slag content was observed, cumulating in 25% decrease in the composites having thrice volumetric content of slag, relative to lime. Composite’s reduced thermal conductivity would be of utmost importance in construction especially, where material’s limited thermal conductivity property is of utmost importance.

Paparan alergen pada saluran napas secara berulang memicu terjadinya reaksi asma alergi. Asma alergi diinduksi oleh degranulasi sel mast yang melepaskan mediator proinflamasi seperti histamin, leukotrien, dan prostaglandin yang memicu terjadinya inflamasi bronkus yang ditandai dengan peningkatan eosinofil bronkus. Peningkatan eosinofil bronkus dapat ditekan oleh asam kafeat dan flavonoid. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak patikan kebo terhadap hitung eosinofil bronkus pada tikus Wistar model asma alergi. Subyek penelitian berupa 25 ekor tikus Wistar jantan dengan berat badan ± 200 g dan berumur 6 minggu, dibagi dalam 5 kelompok yaitu: Kontrol (K), Asma alergi (A), ekstrak patikan kebo 10 (P1), 15 (P2), 20 mg/tikus/hari (P3). Hitung eosinofil bronkus postes diukur setelah 28 hari perlakuan. Hitung eosinofil bronkus dianalisis dengan SPSS versi 23.0 menggunakan uji One Way ANOVA dan dilanjutkan uji post hoc multiple comparison Tukey. Tingkat kemaknaan digunakan p<0,05. Hitung eosinofil bronkus tikus P1, P2, dan P3 lebih rendah secara bermakna dibanding tikus Asma Alergi (p<0.05).

Abstratos e realistas
Authors: Giorgi Artur de Vargas
Published: May 2020

Este ensaio retoma a diferenciação entre as colonizações espanhola e portuguesa, proposta por Sérgio Buarque de Holanda em Raízes do Brasil, para pensar as matrizes respectivamente abstratas e realistas que orientariam a produção de imagens de próceres da independência de nações latino-americanas. A leitura contrastiva de diferentes retratos permite uma análise nuançada desses véus, abstrações e representações, que afinal encobririam o vazio de nossas fundações sociais como um trompe l’oeil.
Recriações à venda? Sophie Taeuber-Arp e o caso da terceira Bienal de São Paulo
Authors: Mari Marcelo
Published: May 2020

Depois de receber prêmio de aquisição na I Bienal de São Paulo, Sophie Taeuber-Arp ganhou grande exposição em sua homenagem na III Bienal, de 1955. Para isso, a Embaixada Suíça organizou, conjuntamente com Jean Arp, a exposição das obras dessa artista, que morrera prematuramente, mas que tinha deixado contribuição seminal para a arte de tendência construtiva. O fato é que a sala especial de Taeuber-Arp na Bienal foi e ainda é a exposição mais completa de suas obras. Na sala expositiva da artista havia, além de pinturas, fotografias, maquete e relevos. Aquilo que não poderia ser trazido foi copiado em fotografia ou mesmo em pintura. Não havendo material explicativo sobre a origem de cada obra, de que se tratava de fotografia ou até mesmo réplica de trabalhos desaparecidos, ou inacessíveis, o público que visitava a Bienal poderia ser confundido pela impressão de que tudo ali fora realmente produzido pela artista suíça, o que não era verdade.
Atlântica Moderna: a natureza feita de crochê e vidro
Authors: Solfa Marilia , Machado Vanessa Rosa
Published: May 2020

A produção da artista Ana Maria Tavares é lembrada pelo diálogo crítico que estabelece com a construção do espaço contemporâneo, especialmente com a arquitetura e o design. Se nas décadas de 1990 e 2000 suas propostas colocavam em questão a configuração dos espaços de trânsito e consumo e suas bem arquitetadas “armadilhas”, a última década marca uma redefinição em sua trajetória. Através da análise da exposição Atlântica Moderna: Purus e Negros, realizada em 2014 no Museu da Vale em Vitória-ES, investigamos o significado da incorporação de peças feitas em crochê em sua produção. Tomando como referência importante a obra da arquiteta Lina Bo Bardi, e em especial seu encontro com o “pré-artesanato” nordestino, Tavares atribui novas camadas à visão política e antropológica que a arquiteta tinha frente ao popular nos anos 1960, incorporando questões que envolvem as relações entre arquitetura, paisagem e natureza.

Authors: Salomão Myriam
Published: May 2020

Pretendemos identificar, analisar e estabelecer possíveis relações do uso de textos da historiografia da arte sobre a tradição clássica presentes e citados direta ou indiretamente no livro Padre Jesuíno de Monte Carmelo (1945), de autoria de Mário de Andrade, textos estes que possivelmente foram utilizados para a construção dos argumentos na biografia e análises das obras do padre pintor. Nesse estudo identificamos as citações a artistas do Renascimento e Barroco e como elas foram utilizadas na construção do texto biográfico.Concomitantemente, destacamos trechos que remetem à presença de linhas teóricas da história e estética da arte. A partir da identificação das citações, verificamos a quais obras ou autores elas pertenciam e se estas integram o acervo de livros remanescentes da biblioteca particular de Mário de Andrade, atualmente pertencente ao Instituto de Estudo Brasileiros na Universidade de São Paulo.
Spectrophotometric determination of sulphite and thiamin hydrochloride using proton transfer reaction-application to water sample and pharmaceutical formation
Authors: A. Abed Al-Hadi Bassima
Published: May 2020

In this research, an easy, acurate and rapid spectrophotometric method for determination of sulphite and thiamine hydrochloride is described. This method used proton transfer reaction between sulphite ion with alizarine at (pH 6.73) to develop red colour adduct that bears maximum absorption at 524 nm. This method was developed to determination of thiamine hydrochloride by bleaching the red colour (alizarine-sulphite product) at the optimum conditions established for the determination of sulphite. Beer’s law is obeyed in the concentration range (10-1000) μg/25ml (0.4-40) of sulphite and 10-1500, μg/25ml (0.4-60) for thiamine hydrochloride at the selected wavelength, the molar absorbtivity 2.6×104 l.mol-1.cm-1 for SO32- and 3.37×104 l.mol-1.cm-1 for thiamine hydrochloride, Sandell's index for sensitivity 0.00307 μg .cm-2 for sulphite  and 0.0100 μg .cm-2  for B1, the precision (RSD) of the method is ±0.23- ± 0.51% sulphite and ±0.15- ±0.25 thiamine hydrochloride. Good recoveries of sulphite and thiamine hydrochloride from water samples and pharmaceutical formation are achieved using the proposed method.

Authors: Ajmi Abd1 Mohammed , Hamdi Razeg1 Khalid , M.S Al-haddad2 Raad
Published: May 2020

In this study,the nanoparticles of zinc oxide were readily prepared  through Hydrothermal process by using zinc nitrate hexahydrate, and Sodium hydroxide as aprecursors. The surface topology, and crystalline structure of prepared ZnO nanoparticles were studied. X-ray diffraction (XRD) revealed that the prepared ZnO nano particles is highly crystalline, having (wurtzite) crystal structure.  The optical analysis by UV–vis showed that these ZnO nano particles have considerable blue shift in the optical band gap energy (Eg = 4.9eV), and this may be to the  quantum confinement effect of nano particles. The FT-IR results shows the  existence of OH, COO, H2O groups the characteristic vibrational modes of Zn–O were identified. and AFM analysis showed that the diameters of the ZnO particles is in ananometer range of (70-74)nm.
