Numerical Simulation of Laminar and Turbulent Methane/Air Flames Based on a DRG-Derived Skeletal Mechanism
Authors: Minuzzi F.C. , Yu Ch. , Maas U.
Published: August 2020

Simulation of turbulent flames using detailed chemical mechanisms is still a challenge in numerical combustion due to the large number of species and the stiffness of the system of governing equations. In this sense, strategies to reduce the size of the detailed model are necessary and one of such models is the well-known directed relation graph (DRG) method. In the present work, a DRG-derived skeletal mechanism developed using only one application for methane/ air simulations is presented and validated for auto-ignition times, laminar flame speed and counterflow flames. The skeletal mechanism is tested for varying the equivalence ratio (ϕ = 0.4, to 3) and pressure (p = 1 to 150 atm). The temperature spans the range from T = 1000 K to T = 2000 K. The relative error, compared with the detailed mechanism, of our proposed model for ignition delay times and flame speed are less than 10% for most of the parameters. The skeletal mechanism is also used to simulate the piloted turbulent jet Sandia Flame D. Results show that this skeletal mechanism can reproduce the main features of laminar and turbulent methane/air flames.
Digital Modeling Accuracy of Direct Metal Laser Sintering Process
Authors: Dmitriyev T. , Manakov S.
Published: August 2020

Products obtained by metal additive manufacturing have exceptional strength properties that can be compared with forged parts, and in some cases, even surpass them. Also, the cost and time of parts manufacture are reduced by two or even three times. Because of this, today’s leading corporations in the field of aerospace industry introducing this technology to its production. To avoid loss of funds and time, the processes of additive manufacturing should be predictable. Simufact Additive is specialized software for additive manufacturing process simulation is dedicated to solving critical issues with metal 3D printing, including significantly reducing distortion; minimize residual stress to avoid failures; optimize the build-up orientation and the support structures. It also enables us to compare simulated parts with the printed sample or measure it as a reference. In other words, the simulated deformations can be estimated concerning the reference geometry. The current work aims to study the deformation of the sample during the Direct Metal Laser Sintering (DMLS) process made from Maraging Steel MS1. Simufact Additive software was used to simulate the printing process. The main idea is to compare the results of the simulation and the real model. EOS M290 metal 3D printer was used to make a test specimen.

Authors: Fekri Masoomeh , Jahed Khaniki Gholamreza , Pirhadi Mohaddeseh , Abbassi Mahdieh
Published: August 2020

Heated meat products are emulsion which have various nutrition materials such as meat as an animal protein and soya as a plant protein. The nutritional value of meat proteins is very high than soya protein but the meat is more expensive than soya which the producers substitute the meat with soya. This study was assessed the soy protein and the total protein contents in some heated meat products collected from food stores in Tehran, Iran. Twenty samples of heated meat products with 40%, 55% and 70% of meat were randomly collected from food stores. The heated meat products samples were transferred to the food analysis lab. The total protein was determined by the macro Kjeldahl method after sample preparation and homogenization. Also, the soy protein content in samples was measured by using the enzyme-linked immunosorbent assay (ELISA) method. Results showed that 4 samples of heated meat products had less total protein content than the standard limit and 16 samples were in accordance with Iranian national standard. Soy protein content in 3 from 8 samples of heated meat products with 40% meat was higher than the standard limit and the others placed in the standard limit (approximate with 4% soy protein). Also, Soy protein content in 6 from 8 samples of heated meat products with 55% meat was higher than the standard limit and only 2 samples were in accordance with the standard limit. All samples of heated meat products with 70% meat set in a standard limit. It was concluded that some heated meat products do not correspond with the Iranian national standard range. The food quality control lab requires doing attention and sensation for correct formulation according to national standard measures.

Evaluation of the entrustable professional activities (EPAs) of the population health promoter domain by North Dakota pharmacists
Authors: Scott David M. , Kelsch Michael E. , Zhang Anqing , Friesner Daniel L.
Published: August 2020

Objective.  Entrustable Professional Activities (EPAs) are a list of professional tasks (with associated competency ratings) that pharmacy educational organizations support, and accreditation organizations require, for assessment by colleges and schools of pharmacy. This manuscript assesses the perceived frequency of performing EPAs in the population health promoter (PHP) domain among pharmacists practicing in North Dakota.

Methods.  This survey assessed the self-reported EPA activities (inclusive of the PHP domain) of registered pharmacists living and practicing in North Dakota. There were 990 pharmacists surveyed, and 457 (46.1%) of pharmacists responded.

Results. Within the PHP domain, pharmacists reported performing “Minimize adverse drug events and medication errors” most frequently (mean=3.4, SD=2.0), followed by “Ensure that patients have been immunized against vaccine-preventable diseases” (mean=2.3, SD 2.3), “Maximize the appropriate use of medications in a population” (mean=2.2, SD 2.3), and “Identify patients at risk for prevalent diseases in a population” (mean=1.3, SD=1.9). In these Core EPAs PHP domains, the clinical pharmacists reported the highest level, followed by pharmacy managers and staff pharmacists.

Conclusion. Pharmacists in North Dakota reported that EPAs in the PHP domain are practiced regularly. Thus, EPAs in the PHP domain have potential as a means to assess outcomes in pharmacy education and practice.

Рефлексивность частного письма как разновидности эго-текстов
Authors: Куварова Елена
Published: August 2020

К числу актуальных проблем современной лингвистики принадлежит выяснение дифференциальных признаков эго-текстов (дневников, писем, мемуаров и т. п.) и изучение языковых средств объективации в этих текстах своего «Я». Целью данной работы было выяснить, как проявляется в текстах частных писем рефлексивность – один из существенных признаков эго-текстов. Материалом исследования стали опубликованные в разных изданиях письма русской интеллигенции ХІХ–ХХ вв. Показано, что рефлексивность является одной из основных категорий, присущих текстам частных писем, наряду с диалогичностью, с которой она соотносится по принципу взаимодополнения на оси коммуникации «адресант – адресат». Исследованный эпистолярий фиксирует разные типы рефлексии: личностную, коммуникативную, интеллектуальную, кооперативную, языковую. Рефлексивность проявляется в эпистолярном тексте такими языковыми средствами, как использование личных и притяжательных местоимений первого лица, местоимений себя, свой; включение в текст письма высказываний, реализующих речевой жанр самопрезентация; широкое употребление эмотивной лексики; воспроизведение средствами синтаксической стилистики некоторых свойств внутренней речи.
К проблеме лексикографической параметризации терминологии исторической лексикологии восточнославянских языков
Authors: Пятаева Наталия
Published: August 2020

За триста лет изучения и лексикографической параметризации лексической системы восточнославянских языков сформировался корпус отраслевой терминологии исторической лексикологии и смежных с ней дисциплин (синхронной лексикологии, семасиологии, этимологии, диалектологии, исторической фонетики и грамматики близкородственных языков), который до настоящего времени не нашёл отражения в терминологическом словаре.

Статья знакомит со сформированным корпусом терминов (1307 единиц) исторической лексикологии и намечает пути отражения его в отраслевом терминологическом словаре алфавитно-гнездового типа, составление которого основано на использовании системы лингвистических методов и методик: методики сплошной выборки терминов и терминологических обозначений из лингвистических словарей, справочников, энциклопедий и научной литературы; методики формирования корпуса отраслевой терминологии исторической лексикологии восточнославянских языков; метода семантического анализа содержания термина и тематического анализа терминологического корпуса; методики разработки терминологических дефиниций.

Словарь будет состоять из двух частей: первая – словарь алфавитно-гнездового типа, вторая – тематический список терминов, объединённых перекрёстными ссылками. Корпус терминов распределяется на 10 тематических групп: теория исторической лексикологии, славянские языки, история восточнославянских языков, этимология, лексикология, семасиология, словообразование, морфология, диалектология, лексикография.

Словарная статья первой части будет включать зоны: 1) заглавное слово или терминологическое сочетание с постановкой ударения и вариантными (синонимичными) терминами, если таковые имеются; 2) необходимые грамматические и//или функциональные пометы; 3) краткая этимология термина; 4) дериваты, имеющие отношение к терминологии исторической лексикологии, с описанием их семантики; 5) дефиниция (со ссылкой на ранее изданный словарь, если она разработана не автором данного словаря); 6) языковые иллюстрации, демонстрирующие явление, поименованное данным термином; 7) ссылка на вторую часть словаря, т.е. указание на тематическую группу, к которой относится термин. В качестве образцов в статье приведены две экспериментальные словарные статьи «Ахрония//панхрония» и «Корень (слова)».

O paradigma Cidade Jardim e o planejamento metropolitano em Londres (1898 - 1944)
Authors: Carmo Julio Cesar Botega do
Published: August 2020

As formas de planejamento metropolitano de maneira recorrente se inserem na esfera das utopias. Das primeiras experiências, como o paradigma cidade-jardim às condicionantes que se apresentam hoje, tem sido alvo de diversas pesquisas e análises. Contudo, do ponto de vista historiográfico, método utilizado nesta pesquisa, a circulação de algumas ideias e conceitos não foi tão explorada, entre eles o que convencionamos denominar planejamento metropolitano. Assim, o metropolitano tem sido estudado sob seus aspectos econômicos, sociais, demográficos, ambientais, entre outros, entretanto, como a ideia de planejamento nesta escala circulou e foi incorporado aos estudos e legislação, permanece um caso a ser aprofundado. Neste texto o objetivo é relacionar dito recorte de planejamento, sua origem e relação com à cidade jardim, se atendo ao caso britânico.

Authors: Carretta Diniz Pedro Henrique , Oliveira de Almeida Caliane Christie
Published: August 2020

Este artigo se insere na temática da publicidade e do patrimônio histórico, tendo como foco a cidade de Passo Fundo/RS, Brasil. Objetivou-se identificar e mapear as edificações com referência ao Art Déco na cidade, bem como analisar o impacto dos anúncios publicitários neste patrimônio moderno. Para tanto, foi preciso realizar estudos bibliográficos relacionados às temáticas da publicidade, do Art Déco e do processo de formação e transformação de Passo Fundo, com o intuito de entender a importância da mencionada linguagem arquitetônica no contexto da cidade e expor o poder de descaracterização que a falta de normatização publicitária exerce nas edificações de valor histórico. Também foram realizados levantamentos in loco dos exemplares Déco identificados, bem como levantamentos documentais de leis municipais relacionadas ao patrimônio e ao controle publicitário em vigor no Brasil. Grande parte das edificações identificadas estão em ruim ou péssimo estado de conservação e possuem anúncios excessivamente grandes e despadronizados, comprometendo a percepção do léxico arquitetônico e, consequentemente, seu valor histórico e cultural.
Qualitative modelling of accompaniment’s postures in training spatio-temporal analysis
Authors: Radid Mohamed , Lotfi Said , Akoul Mustapha
Published: August 2020

This is a qualitative study that aims at exploring textual data in a coherent set of journal articles on the theme of educational and training support. This textual study allowed us to identify four different postures in all our analyses. Firstly, the time allocated to accompaniment: moving from permanent to periodicals. In the second place, it is about the space where the exchanges between the person being accompanied and the accompanier take place: from proximity to distance in exchanges. On the theoretical level, the aim of this article is to propose a qualitative model through four postures of accompaniment in training and education. On a practical level, it also aims at clarifying the specificities of these four postures, the typical tools of their exercises, the expected effects and the conditions of their application and, finally, the limits of their adoption in different contexts. The relevance of this work is the prescription of a progressive approach on a set of characteristics specific to each of the four postures observed. This progressive continuum obeys an evolutionary dynamic going from the most caring posture for the person being supported to the most empowering for him.
Keywords: Accompaniment, distance, space-time, modelling, postures, proximity

Published: August 2020

En este estudio se propuso evaluar una estrategia utilizando Partial Least Squares (PLS) como herramienta quimiométrica para establecer la robustez del proceso de degradación fotosensibilizada de Bisfenol A (BPA) en efluentes simulados. En esta la etapa del trabajo de investigación, se llevó a cabo la validación de la metodología que permitió la cuantificación de BPA mezclado con el fotosensibilizador Eosin Y (EOS) en solución acuosa. Utilizando la espectrofotometría como técnica de seguimiento, fue posible establecer el número óptimo de factores y el rango de longitud de onda, y determinar que es posible asegurar la cuantificación de BPA mediante PLS al demostrar la formación de complejos entre BPA y EOS. Los resultados de RMSE fueron 0,004237 a 284 nm y 0,009167 a 524 nm, lo que demuestra una buena solidez en el análisis. A continuación, se realizaron pruebas preliminares sobre el efecto de la luz directa utilizando una lámpara de mercurio como fuente de irradiación. En el caso del BPA se determinó que se alcanza el 100% de degradación a los 100 minutos. El fotosensibilizador se fotodegradó a los 50 minutos de exposición a la luz directa. La mezcla de los dos compuestos en el análisis preliminar podría demostrar un efecto de pantalla por parte del fotosensibilizador.
PENSAR A/NA EXISTÊNCIA: PARADOXO E ONTOLOGIA
Authors: Drawin Carlos Roberto
Published: August 2020

O meu texto toma como referência central o pensamento de Sören Kierkegaard, mas não tem a pretensão de oferecer um estudo erudito ou espe­cializado do filósofo. Possui antes um perfil ensaístico, embora procure evitar tanto a mera digressão, quanto a abordagem de uma sucessão arbitrária de te­mas. A leitura de Kierkegaard não é em si mesma o meu objetivo, embora ela ocupe uma boa parte da exposição. Na verdade, ela parte de um determinado horizonte conceptual que poderia ser resumido na ideia do esquecimento das raízes existenciais do pensar. Assim, o texto está dividido em quatro partes. Na primeira é delineada a problemática filosófica tomada como ponto de partida. Na segunda e na terceira partes focalizei alguns aspectos dos escritos de Kierkegaard, sobretudo do período de 1843 a 1846, com a intenção de mostrar a fecundidade de seu modo paradoxal de fazer filosofia. A ênfase recaiu na leitura do primeiro capítulo de “O conceito de angústia”. Na última parte tratei de alguns aspectos da ressonância kierkegaardiana em Karl Jaspers e Martin Heidegger. No entanto, este último autor esteve presente desde o início na demarcação deste estudo.
KANT E HOBBES: COERÊNCIA E INCOERÊNCIA OBRIGACIONAL EM FACE DE UM ESTADO TIRÂNICO OU INJUSTO
Authors: Dutra Delamar José Volpato
Published: August 2020

O texto apresenta o conceito de obrigação em Hobbes e em Kant. Argumenta-se que Kant não foi capaz de manter a coerência de seu conceito de obrigação quando tratou da sua aplicação ao caso extremo do jus necessitatis, pois teve que distinguir entre punibilidade e culpabilidade. Hobbes, por seu turno, pôde manter a coerência de seu conceito de obrigação mesmo para este caso.
NOTAS SOBRE A FILOSOFIA DE BYUNG-CHUL HAN: A EXPERIÊNCIA ESTÉTICA NA ERA DIGITAL
Authors: Pozzer da Silveira Sara Juliana
Published: August 2020

Este artigo tem como objetivo discutir alguns temas centrais da filosofia de Byung-Chul Han. O trânsito por várias obras, todas complexas e importantes, não pretende esgotar nenhum assunto, mas ajudar a entender nossa vida na era digital. Assim, inicialmente, abordaremos as principais diferenças estabelecidas por Han entre a nova sociedade digital e a sociedade disciplinar do século pas­sado. As mudanças dizem respeito ao próprio caráter/natureza do pensamento e da percepção do mundo causadas por um modo de vida onde os processos operacionais das máquinas digitais se tornam paradigmáticos. Mostraremos em seguida como Han, ao propor um novo modelo de pensamento em oposição ao pensamento operacional, revaloriza as ações rituais como práticas simbólicas, bem como insiste numa revisão do pensamento de Hegel, especialmente das noções de totalidade e alteridade. Para a compreensão do narcisismo da era digital, re­corremos à reflexão estética do autor, porque a experiência estética na era digital está ameaçada, devido, entre outros elementos, à incapacidade do indivíduo de se abandonar ao outro. Nesse ponto, a reflexão é realizada principalmente em relação às estéticas de Kant e Adorno.

Published: August 2020

UEDVT still remains an underdiagnosed entity due to a significant percentage of patients who remain asymptomatic. The etiology of UEDVT is overwhelmingly attributed to secondary causes including but not limited to central venous access devices and malignancy. Treatment modalities include anticoagulation, catheter directed thrombolysis, percutaneous mechanical thrombectomy or a multimodality approach along with the management of underlying etiology. We describe a case of a female with breast cancer, who came with left UEDVT and CVC malfunction and was successfully treated using the ClotTriever system to maintain continuous intravenous access.

Finally, we provide future direction to negate these false claims linked with 5G.
Heat Stability of Proteins and Its Exploitation for Purification of Heat-Stable Proteins
Authors: Ahmad Muhammad , Tahir Aisha , Salman Anjum Rana
Published: August 2020

Proteins possess complex three-dimensional structures, and these structures are stable only within specific ranges of temperature which mostly correspond to the temperature ranges of the host organisms. However, few exceptional proteins, called heat-stable proteins, are stable at temperatures that are substantially higher than those tolerated by the host organisms themselves. Most of the heat-stable proteins possess heat stability to perform their functions at high temperatures, but some of them are intrinsically heat-stable due to their structure. Heat-stable proteins are usually divided into three or four groups depending upon the intricacies of their structures and thermal behaviors. Their peculiar property, i.e. heat-stability, makes them very valuable in applications such as polymerase chain reaction, industrial processes requiring high temperature, and protein engineering. Heat-stability also makes it feasible to purify such proteins, from the rest of the heat-labile proteins, using a simple heat-treatment method. Moreover, heat treatment can be used as a combined cell-lysis and protein purification step which, as compared to conventional methods, can result in a higher yield of heat-stable proteins. Furthermore, some special heat-stable proteins, i.e. intrinsically disordered proteins (which include the proteins involved in important neurodegenerative diseases), need heat-treatment step, in some cases, as the only way for their successful purification and study. Hence, this paper provides a first-ever comprehensive review of all major aspects of heat-stable proteins, i.e., their structure, evolution, classification, significance, and heat-treatment mediated purification.

Despite the 12-lead electrocardiogram (ECG) being the gold standard in evaluating clinical presentations of arrythmias of various kinds, several notable limitations, namely in accuracy and localization, have recently garnered concern with respect to administering appropriate therapeutic measures. The following text puts these limitations under the spotlight, highlighting the difficulty and challenging nature of standard ECG analysis and therapeutic measures, while simultaneously showing a novel body surface electrocardiographic mapping system that utilizes 3D spatial imaging and pinpoint localization algorithms in order to compensate for the shortcomings of the standard ECG, thereby providing higher precision data collection. We provide a brief overview of the novel device in a selection of arrhythmic demographics, along with its validity and reliability, while illustrating the benefits and positive outcomes of its utility.

Today, transit control systems go beyond simple controllers located at the intersections of our streets, involving large companies in the field, which with the implementation and use of sophisticated equipment encompass endless new and advanced technologies that manage to give control to the massive automotive park, thus ensuring fluidity and road safety. Many of these systems are used in the big world capitals, which is why the model used in Santiago, Chile is a system applied and brought directly by the SIEMENS Company of England (specifically the system used in the City of London). It is capable of transmitting the different control signals in a similar and digital way from the different interconnected devices in and out of the road infrastructure.

This paper aims to describe a passive approach to reduce the energy demand for an existing building and can be made through an improvement of the design of the thermal envelope. The essential article goal is to simulate thermal construction responses in dependence on changing different materials of the construction of the building and also with less energy usage to design a more effective cooling system. In this approach, we simulate the building with different materials: three local materials (compressed earth, lateritic, and raw material) and one modern (Hollow cement) used in Burkina Faso and an energy analysis of the building has been carried out. The numerical optimization of the building design has been performed dynamically for these four materials using the COMSOL multiphysics simulation tool. The model treated is determining the internal temperature and cooling demand concerning a tertiary building in Burkina Faso like a classroom, which is located in a hot and dry climate to improve the indoor quality of the classroom knowing the importance of the thermal comfort in the room for socio-economic performance efficiency and well-being. The analysis result of these four materials shows that energy can be saved if we use local materials instead of the modern one because around 4KW of energy can be saving with local materials. The use of local materials in the building design can be an option for reducing the heat transfer into the room and at the same time the energy consumption.

Published: August 2020

Salah satu langkah dalam algoritma transportasi fuzzy untuk penyelesaian masalah transportasi fuzzy yang mempunyai ranking biaya fuzzy sama yaitu memilih secara bebas biaya fuzzy yang mempunyai ranking sama untuk dijadikan sel basis. Padahal pemilihan secara bebas tersebut dapat berpengaruh terhadap solusi, iterasi, dan nilai optimal fuzzy yang dihasilkan. Oleh karena itu, pada artikel ini diperkenalkan suatu modifikasi algoritma transportasi fuzzy dengan menggunakan new function ranking yang diperoleh dari kombinasi antara metode perankingan bilangan fuzzy yaitu ranking function dan metode pembobotan yaitu simple additive weighting. Selanjutnya dilakukan simulasi numerik menggunakan modifikasi algoritma transportasi fuzzy dan hasilnya dibandingkan dengan algoritma yang sudah ada. Dari studi kasus diperoleh bahwa modifikasi algoritma transportasi fuzzy menghasilkan perankingan yang lebih baik, solusi dan nilai optimal fuzzy yang berbeda, serta iterasi yang lebih cepat dari algoritma transportasi yang sudah ada.
