This paper presents new results of computational experiments on the implementation of Overfire Air (OFA) technologies using an example of a combustion chamber of the BKZ-75 boiler of the Shakhtinskaya power plant (Shakhtinsk, Kazakhstan) burning high-ash Karaganda coal. The effect of mass air flow through special nozzles located above the burner level on the flow aerodynamics, temperature fields, concentration fields of carbon monoxide CO and nitrogen NO over the entire volume of the combustion chamber was studied. The studied characteristics were compared for various percentages of supplying additional air through OFA injectors: OFA is 0% (basic version), 10% and 18 %. It was shown that the installation of OFA injectors leads to a change in the field of the total velocity vector, temperature, and concentrations of carbon oxides and nitrogen. An increase in the percentage of air supplied through OFA injectors to 18% leads to a decrease in the concentrations of carbon monoxide CO by about 36% and nitrogen oxide NO by 25% compared with the base case. The obtained results will optimize the process of burning pulverized fuel in the combustion chamber of the BKZ-75 boiler, increase the efficiency of fuel burnout, reduce harmful emissions and introduce OFAtechnology at other coal-burning thermal power plants.

Authors: Ižvolt Libor , Dobeš Peter , Mečár Martin
Published: July 2020

Extruded polystyrene (XPS) and its excellent thermal insulation properties have been known for over 60 years. Due to its thermal, mechanical, but also deformation properties, XPS has a universal application, not only in the construction industry. This paper presents the results of the first series of experimental measurements of the deformation resistance of the sub-ballast layers with a built-in XPS thermal insulation layer and the sub-ballast layers with a standard structure (crushed aggregate sub-ballast layer). The aim of the first series of experimental measurements was to determine the impact of placing the XPS layer at the subgrade surface level (deformation resistance of subgrade surface E0 = approx. 10MPa or 30MPa) on the deformation resistance of the sub-ballast layers and then to determine the necessary thickness of the sub-ballast layer in relation to the required deformation resistance at the sub-ballast upper surface. Experimental measurements carried out so far show that the application of XPS boards in the sub-ballast layers has almost no or minimal effect on its deformation resistance. Since XPS boards have significantly better thermal technical properties compared to crushed aggregate, considerable savings of this material can be achieved in areas with unfavorable climatic conditions (high values of air frost index).

A concepção da clínica cada vez mais próxima da realidade considerando para tal as variáveis que podem interferir no processo e que não estejam necessariamente no escopo deste tem sido cada vez mais discutido. A metodologia de roda de conversa como forma de empoderamento e capacitação de familiares tem sido descrita como uma estratégia eficaz nessa perspectiva. Objetivo: compreender como a utilização da estratégia da roda de conversa como forma de intervenção junto às famílias de crianças com diagnóstico de alteração de linguagem auxilia no processo de desenvolvimento comunicativo destes indivíduos. O formato de intervenção sem padronização prévia possibilitou que as famílias pudessem elaborar suas dúvidas e angustias, assim como seus anseios e em muitos casos a troca de informações e conhecimento se deu na base dos grupos e não necessariamente com a intervenção do profissional. Método: participaram vinte e dois pais e ou cuidadores de crianças com diagnóstico de alteração de linguagem divididos em dois grupos: Gagueira Desenvolvimental Persistente (GDP) e Transtorno do Espectro Autista (TEA) em atendimento fonoaudiológico. Resultados: pode-se constatar que os sentimentos e relações quanto o impacto da comunicação são comuns a ambos os grupos. Conclui-se que, em ambos os grupos, os relatos perpassam.

Educação como prática democrática versus monitoramento da qualidade da educação em Minas Gerais / Education as a democratic practice versus monitoring the quality of education in Minas Gerais
Authors: Araújo Abelardo Bento
Published: July 2020

O artigo é um recorte de uma tese de doutorado em que se analisou a política de monitoramento da qualidade da educação em Minas Gerais, tendo como referência a discussão da natureza do trabalho educativo no âmbito da economia política aplicada à educação. De forma diferente da tese, em que se analisam todos os dados em conjunto, neste texto discute-se uma questão específica emergente nas falas dos sujeitos: a relação entre as avaliações externas e a educação entendida como prática que necessita ser democrática. A partir de uma pesquisa qualitativa em que se utilizaram entrevistas de quinze profissionais da educação, demonstra-se que, apesar de os profissionais considerarem a avaliação externa necessária e importante, trechos de suas falas revelam imposições da política e destacam falhas que podem ser associadas à negação da condição de sujeitos daqueles que realizam o processo educativo na escola, dos alunos e até da comunidade externa.

Tem como objetivo analisar a lírica feminina e a construção do seu imaginário poético, pondo em evidência a temática erótica, numa perspectiva teórico-metodológica-interpretativa, visando sua inserção em sala de aula. Para tanto, selecionamos a poesia erótica de três poetisas cearenses: Regine Limaverde, Aila Sampaio e Hermínia Lima, que nos oferece um material poético rico em imagens. Nosso estudo está em consonância com Bosi (1998) Candido (2006) e Pinheiro (2018), ao colocar a poesia numa prática de leitura; com Octavio Paz (1994, 2012), sobre a eroticidade poética e com Bachelard (1988), que tece as ferramentas necessárias para a compreensão do imaginário poético. A poesia é bendita porque traduz nossa humanidade, sem disfarce, e nos adverte para o sentido da vida, pela escrita de muitas mulheres.
Weaving Together a Global Civilization that Nurtures Justice and Peace: A Vision for Muslim Educators at Indonesia’s UIN Institutions
Authors: Beck Martha C.
Published: July 2020

This paper links the religious pluralism of Pancasila, Indonesia’s political ideology, with numerous ancient and contemporary worldviews, including Erwin Lazlo’s Systems View of the World, the “Functionalism” of Paul Davies and Richard Feynman, both theoretical physicists, and Aristotle. It gives extensive descriptions of Aristotle’s virtues: self-control, courage, even-temperedness, wise ambition, appropriate pride, a sense of humor, self-knowledge, sociability, justice, moderation in wealth, good judgment about what sorts of laws will weave people together in positive ways, including how to distribute social goods, how to punish law-breakers, and how to apply laws to specific cases within a context of the integration of nature and culture.  It then explains how Confucius, Buddha, Muhammad and Jesus either exercised those virtues throughout their lives or held those with power accountable for using power to promote human well-being. It explains Aristotle’s model for childhood education as a process of habituation from childhood on that integrates the moral and intellectual virtues throughout life. The paper makes suggestions for how to use the stories of these great spiritual leaders to structure a comprehensive system of integrated education. The paper explains how this model is compatible with the United Nations’ Capabilities model for development. Using this model of integrated education, members of all the world’s religions and humanists of all types can work together toward world peace.
Why Muslims should Maintain their Dignity in Worldly Life: A Critical Consideration on Said Nursi’s Insight on the Meaning of “Theology of Hope” as Reflected in His Damascus Sermon
Authors: Saleh Fauzan
Published: July 2020

“At one time Muslim culture led the world in knowledge and prosperity. Now, in most respect, it lags far behind. What are the factors that led to its rise and subsequent fall?” (Perkins, 2003). Muslims fell under the Western domination for many centuries. As a result, they have lost their authority to administer their own matters independently. Whereas Muslims believe that they should attain worldly contentment and after life happiness altogether, in reality, they gain only a modest attainment to improve their prosperity and accordingly lose their political as well as cultural dignity. They have been overshadowed by the West in many aspects of political and cultural affairs. But what made the West prosperous and triumphant over Muslim nations in general? To some extent, as one might believe, it is because they have adopted “prosperity theology.” While the term itself is controversial among Christian theologians, the issue has roused a profound awareness among Western people about the importance of personal empowerment, proposing that it is God’s will for humans to live prosperously. What did Nursi say about the necessity of cultivating prosperous life in Islam and what did he say about the demand to maintain dignity in this worldly life? This article tries to examine Nursi’s idea on the necessity of gaining worldly prosperity for advancing Muslim civilization as well as of maintaining their dignity by examining his insights on the “theology of hope” as reflected in his “Damascus Sermon” and other works compiled in his voluminous Risalei Nur.
Fostering World Peace Through ‘Cultures of Meaning’: A Case Study of Shaykh Hamdi Ben Aissa and the Sanad Collective
Authors: Edaibat Omar
Published: July 2020

When considering the question of world peace, many of the political and intellectual responses of our age continue to operate within a well-defined prism that privileges secular, diplomatic, political, and economic solutions that have failed to adequately diagnose the root causes of this persistent global challenge. Further still, religion is frequently regarded as an exclusionary and divisive force, or worse still as an obstacle, that is to be channeled and contained. This paper seeks to address this imbalance. Part I seeks to provide a wider critique of the contemporary status quo and to proffer a diagnosis of the underlying root causes of our current global crises. In doing so, I build upon existing critical academic scholarship, with a special focus on Rajani Kanth’s forceful critique of ‘Euro-modernism’ and Steven D. Smith’s ‘cage’ of secular discourse. Here, I argue that the central malaise of our age relates to the shrinking landscapes of ‘meaning’ in our expanding global monoculture, a challenge that the paradigm of traditional religion is well suited to address.  Part II, seeks to bolster this point further through an illustrative example of one such local communal solution in practice working from within the rich resources of Islamic spiritual tradition in my case study of Shaykh Hamdi Ben Aissa and his dynamic community, the Sanad Collective, in Eastern Canada.
Placement of Entries, Phono-morphological Information and Emotive Idioms in Al-`Inarah Al-Tahzibiyyah Kamoes Arab-Melajoe
Authors: Imamuddin Basuni
Published: July 2020

In Indonesia there are two kinds of bilingual Arabic-Malay dictionaries and 26 Arabic-Indonesian dictionaries (1925-2018), but all refer to the Dictionary of Al-`Inārah Al-Thżībiyyah Kamoes Arab Melajoe by H. Moehammad Fadloellah and B.Th. Brondgeest (1925). Based on research (Imamuddin, 2017), the placement of entries and subentries is often not consistent. Therefore, there is an urgency to research and revise the dictionary which is the "parent" of the 28 dictionaries. It is expected that the 28 dictionaries can be updated so that inaccuracies can be avoided. To propose research and revisions to the "parent" work, the factors analyzed are entries and subentries. Phonological information is given to readers so that they know the changes that occur in a word. Al-`Inārah provides this information. Morphological information also provides an explanation of the origin of words in Arabic. Therefore, the analysis will be accompanied by the book entitled Syaza Al-Urf fi Fan Al-Sharf (1980). Idiomatic structure is also presented by the author so that the reader knows that certain verbs must also be accompanied by certain prepositions.

Vulgarly Called The Throat-Distemper: New Jersey’s Two-Century Struggle Against Diphtheria
Authors: Moss Sandra W.
Published: July 2020

In 1740, minister and physician Jonathan Dickinson of Elizabethtown, New Jersey, published “Observations on that Terrible Disease Vulgarly Called the Throat-Distemper,” a short treatise on the diagnosis and treatment of epidemic diphtheria for the benefit of physicians in Boston. Dickinson’s pamphlet was a landmark in American colonial medical literature. It was New Jersey’s first—and last—important original contribution to the medical literature on diphtheria. For the next two centuries, New Jersey, with no medical colleges or prestigious teaching hospitals of its own, would import the medical knowledge and innovations necessary to control and finally eradicate the disease that cruelly killed thousands of New Jersey children in the two centuries following Dickinson’s report. This article examines the processes by which New Jersey practitioners and public health officers imported, processed, disseminated, and applied the lessons of the germ theory and immunology in their two-century quest to banish one of the great scourges of childhood.
From Garden State to Gun Control State: New Jersey’s 1966 Firearms Law and the NRA’s Rise as a Political Lobby
Authors: Rasmussen Chris
Published: July 2020

In 1966, the New Jersey legislature passed An Act Concerning Firearms and Other Dangerous Weapons, which imposed significant regulations on gun buyers and dealers. Two years later, members of Congress frequently cited the Garden State’s tough gun control law as a model for the Gun Control Act of 1968. Although New Jersey’s 1966 firearms law has received little attention from scholars, the battle over gun control in New Jersey marked a significant turning point in the nationwide debate between supporters and opponents of gun control and exposed political fissures that endure today. The National Rifle Association (NRA) mobilized its membership to pressure New Jersey legislators to reject gun control. In its effort to oppose gun control in New Jersey, the NRA honed its arguments that gun control infringed upon citizens’ Second Amendment right “to keep and bear arms,” contended that gun laws would not reduce crime, and charged that keeping records of gun sales would ultimately lead to confiscation of firearms. The NRA’s fight against gun control in Trenton revealed the organization’s enormous influence and signaled its emergence as one of the most effective political interest groups in the United States.

Metafora ciemnej nocy w dziełach Johna Henry’ego Newmana
Authors: Lisowska Natasza
Published: July 2020

The metaphor of dark night has been deeply rooted by John Henry Newman in the Bible, as evidenced in his sermons. In addition, it results from the inspiration of works of the Fathers of the Church, including St. Gregory of Nazianzus, whose poetry he valued, as well as it was taken over from Anglican theologians, Lancelot Andrewes, Bishop Winchester and Thomas Sherlock, Bishop of London. Apparently, this metaphor resounded in The Pillar of the Cloud, and other works confi rm the interpretation that the dark night depicts whole life of man as a pilgrim. Faith helps him to lean on God who leads him home. Certain similarities with this metaphor also occur in the poetry of Luis Rosales, a 20th-century Spanish poet. The dark night is also the season that fell after original sin, making the world unfriendly to man; henceforth he is subject to ignorance, sin and death. However, a believer can see some positive signs that night, which indicate the truth that the world is moving to the end of its path.
A new nine-node element for analysing plates with varying thickness using basic displacement functions
Authors: Tayyebi K. , Haghighi A. M. , Attarnejad R.
Published: July 2020

The capability of the Finite Element Method in producing accurate and efficient results largely depends on the shape functions adopted to frame the displacement field inside the element. In this paper, a new nine-node Lagrangian element was developed to analyse thin plates with varying cross-sections using the shape functions obtained for non-prismatic straight beams with minimum number of elements. The formulated shape functions, which represent vertical displacements and rotations throughout elements, are rooted from a purely mechanical functions called Basic Displacement Functions (BDFs). These functions are obtained by implementing the force method in Euler–Bernoulli beam theory, which ensures that equilibrium equation is satisfied in all interior points of elements. To verify the competency of the proposed element, solutions for the static analysis of isotropic rectangular plates under various loading conditions, together with free vibration analysis of plates with linear thickness variation were obtained and compared with the previous literature. Results showed that the proposed nine-node Lagrangian element was computationally more cost-effective compared to other competing methods when small number of elements is employed.

Authors: Hegde Ananda , Sharma Sathyashankara , Shankar M. C Gowri
Published: July 2020

When the ductile iron which is also known as Spheroidal Graphite (SG) iron, is subjected to austempering heat treatment, the material is known as austempered ductile iron (ADI). This material has good mechanical properties and has various applications in different fields. This revolutionary material with its excellent combination of strength, ductility, toughness and wear resistance has the potential to replace some of the commonly used conventional materials such as steel, aluminium and other light weight alloys as it offers production advantage as well. One of the problems encountered during manufacturing is machining of ADI parts owing to its high hardness and wear resistance. Many researchers over a period of time have reported the machinability aspects of the ADI. This paper presents a review on the developments made on the machinability aspects of ADI along with other mechanical properties.
Characterization of cohesive model and bridging laws in mode I and II fracture in nano composite laminates
Authors: Ghabezi P. , Farahani M.
Published: July 2020

The cohesive model and traction-separation curves have brought a considerable possibility for researchers and fracture engineers to assess and simulate failure in composite laminates. Reliable determination of the traction–separation laws is very pivotal to the success of this approach in finite element methods. The objective of this paper is assessment of nanoparticles effect on bridging laws, cohesive mechanism and traction-separation parameters of nanocomposites mode I and II fracture. To do this analyzing of the experimental data from double cantilever beam, and end notched flexure tests including construction of the R-curves (energy release rate versus crack length), reconstruction of these curves in terms of the pre-crack tip opening and sliding displacement, and calculation of the corresponding bridging and traction-separation laws through the J-integral approach were carried out. For the calculation of the energy release rate in Mode I, three corresponding data reduction schemes namely Corrected Beam Theory, Experimental Compliance Method and Modified Compliance Calibration are utilized, while Compliance Calibration Method, Corrected Beam Theory and Compliance-Based Beam and II fracture are applied for that of mode II. The main concern of this research is introduction of critical parameters of two modified models to simulate mode I and II fracture. Adding 0.43 wt% nanoparticles to composite DCB samples leads to increase of 116%, 68% and 70% in GI,0 calculated by CBT, ECM and MCC respectively, and a 72% increase in GI,ss is measured by CBT, while this value for ECM and MCC is 110% and 48%. Adding 0.2 wt% nanoparticles to the composite samples results in 86% (50 MPa) increase in critical stress in mode II fracture calculated by method CBBM. This method presented the lowest value for critical displacement, fluctuated between 0.08-.11 mm in mode II.
Gravimetric, electrochemical and surface study on the good’s buffer ionic liquid as corrosion inhibitor for carbon steel in acidic medium
Authors: Nanthini R. , Mutalib M. I. , Kurnia K. A.
Published: July 2020

This corrosion study assessed the inhibition performance of carbon steel in 1 M of hydrochloric acid (HCl) using Good’s buffer ionic liquids (GBIL) namely 1-Butyl-3-methylimidazolium 2-(N-Morpholino) propane, [BMIM][MOPS] using electrochemical impedance, potentiodynamic polarization, and weight loss (gravimetric) measurements. GBIL are synthesized by the combination of Good's buffer as anion and various organic bases as the cation. The gravimetric measurements exhibit higher reduction in weight for carbon steel exposed to the acidic environment in the absence of corrosion inhibitor (CI) as compared to carbon steel immersed in the presence of inhibitor molecule. Potentiodynamic polarization study indicates that the synthesized inhibitor acted as a mixed type inhibitor. The inhibition efficiency increases with increase in the concentration of [BMIM][MOPS]. Corrosion protection efficiency ranging from 88% to 90% was featured at 800 ppm of CI in the HCl medium. The adsorption of [BMIM][MOPS] on the carbon steel surface was described by the Langmuir's adsorption isotherm. The scanning electron micrographs inspected the morphology of the carbon steel surface exposed to the solution without and with the presence of inhibitor. The result showed that compound effectively suppressed corrosion by the appearance of an improved surface structure of carbon steel with increasing concentration of [BMIM][MOPS].

Published: July 2020

Vibration-based monitoring and diagnosis provide an excellent and reliable monitoring strategies for maintaining and sustaining a million dollars of industrial assets. The signal processing method is one of the key elements in gearbox fault diagnosis for extracting most useful information from raw vibration signals. Variational mode decomposition (VMD) is one of the recent signal processing methods that helps to solve many limitations in traditional signal processing method. However, pre-determine the input parameters especially the mode number become a challenging task for using this method. Then, this study aims to propose an iterative approach for selecting the mode number for the VMD method by using the normalized mean value (NMV) plot. The NMV value is calculates based on the ratio of a summation of VMD modes and the input signals. The result shows that the proposed iterative VMD approach can select an accurate mode number for the VMD method. Then, the vibration signals decomposed into different VMD modes and used for gearbox fault diagnosis. Statistical features have been extracted from the selected VMD modes and pass into extreme learning machine (ELM) for fault classification. Iterative VMD-ELM provide significance improvement of about 20% higher accuracy in classification result as compared with EMD-ELM. Hence, this research study offers a new mean for gearbox diagnosis strategy.

Authors: Nayak Avijit , Nayak R. K.
Published: July 2020

This paper focuses on establishing the limiting value of input heat flux for thermoelectric generators (TEG) under different environmental and operating conditions. The current study investigates the limiting input heat flux for TEG’s with allowable hot side temperature of 150.A fin block with 8 fin configuration and fin length of 60 mm is chosen as heat sink configuration for TEG. Computational Fluid Dynamics (CFD) model is developed and analyzed in this work after validation with published experimental results. CFD model consists of 4 TEGs encapsulated within a target block and a finned block, placed within a low speed wind tunnel. Forced laminar air flow in the wind tunnel up to 14 m/s simulates the outdoor wind conditions. Concentrated solar flux is applied to the face of the target block. Effect of ambient air temperature, fin material is studied. Angle of Attack (AOA) and wind direction which arises due to the 2 axis tacking of sun by Fresnel lens concentrator has also been studied and it is observed that maximum heat flux reaches 24,850 W/m2 for the TEG at 14 m/s wind speed, 24,000 W/m2 for 30Angle of Attack (AOA) under 5 m/s wind velocity. It is also observed that maximum heat flux varies by 147.77% with a change in wind velocity from 0 to 5 m/s, while the change is 11.43% when the change from 5 to 14 m/s.

Published: July 2020

Transverse rumble strips (TRS) are commonly used as traffic calming measure in the vicinity of premises. So far research have been extensively concentrated on the effect of vehicle type and speed on the noise produced by TRS, and very little research focused on the effect of vehicle weight.  Do these vehicles produce extremely higher sound level parallel to their heavier weight? This is important as in reality, traffic flow consist of light, medium and heavy vehicles, which are also important sources of noise. This study investigated the effect of vehicle weight, such as gross vehicle weight (GVW) when transited on TRS, particularly with emphasis on impulsivity content. The objectives of this research were to: (1) determine the effect of GVW on noise generation when a vehicle transits on TRS and (2) assess the effect of GVW on the impulsivity of noise. Data from vehicles with weight between 800 kg - 8000 kg were collected based on previous research where these vehicles were tested on speed values of 30km/h and 50km/h. It was found that when the vehicles transited on TRS, the generated noise was strongly related with the vehicle weights (R2=0.71) higher than those normal road surface (R2=0.49). However, the changes of noise were not well represented by direct relation. It was found that TRS can increase and decrease the sound pressure level, depending on GVW, but on average, TRS can increase the sound pressure level by 1 dBA. Despite that, TRS was found to have an impulsive characteristic within the tested speed range. This finding can facilitate the authority to evaluate the environmental noise produced by TRS.

Critical lifetime of HDPE pipes through damage and reliability models
Authors: Majid F. , Elghorba M.
Published: July 2020

Damage models are not directly applicable on high-density polyethylene (HDPE) pipes. In this paper, static and strain-unified theory damage models are adapted to fit the HDPE case by substituting the dynamic tests’ endurance limits by preloading simulation through notch and stiffness evaluation. Then, tensile and burst tests are following up to evaluate the specimens’ residual life. Compared to virgin specimens, the rupture limit of old HDPE pipes’ specimens had dropped significantly and their elongation decreased from 275 mm to about 26 mm. The degradation of the seven categories of specimens are different. Indeed, the degradation is too noticeable, disappearance of the plastic phase, for the categories 6 and 7, which are in the bottom of the pipe. Then, a reduced plastic phase on the lateral categories 4 and 5 showing an important impact of degradations. Finally, a larger plastic phase for the categories 1 and 2 taken from the top of the pipe, showing a medium impact of degradation. Thus, the use of the stiffness factor, reflecting the variability of degradation of the different categories of specimens, and the thickness reduction as life fractions for both aged and neat HDPE specimens was possible. The developed strains damage model compared to static burst pressures’ one confirmed the damage stages and the critical life fraction of HDPE pipes. By comparing these models, the drastic change of HDPE pipes’ behavior, from a ductile to a brittle one, have been proved. These findings allowed us to find out the critical life fraction of neat and old HDPE pipes, which has been confirmed by comparing the burst pressure curves of a notched and an old pipe. The presented approach is cost effective allowing a deep analysis of HDPE pipes failure and damage quantification through simply made models based on static tensile and burst test instead of tedious and very costly dynamic ones.

The stress distribution of cruciform shape welded joints is analyzed by finite element codes ABAQUS. Welded joints with various weld shapes and sizes are investigated to estimate the fatigue life of different joints. The fatigue behavior is evaluated under constant amplitude loading (R=0.1). The aim of this work is fatigue behavior evaluation of fillet welded cruciform joint for different weld geometry. The weld geometry are considered: concave, convex and flat weld shape of different weld sizes.  The stress intensity factor (SIF) of a TI 6AL4V, is calculated by using Extended finite element method (XFEM) in ABAQUS software. Simulations of fatigue life for different weld shapes at different stresses are analyzed and crack initiations are identified the number of severe fatigue life cycles which are obtained are very close to the theoretical values. In present study the importance of XEFM method is recognized to predict the crack growth rate for convex specimen which is subjected maximum fatigue stress.

Published: July 2020

In the present study, the thermal behavior of pure Al6061 and fly ash reinforced Al6061 with varying particulate sizes were investigated for the first time. Metal matrix syntactic foams of ceramic fly ash (4 – 16 wt. %) embedded in aluminum (Al6061) matrix have been fabricated by using stir casting technique with different fly ash particulate sizes of size below 50µm and 53µm-100µm, respectively. The microstructural characteristics were studied by using scanning electron microscopy (SEM). It has been observed that there is a uniform distribution of lower particulate size fly ash as compared to higher particulate size in the aluminium matrix respectively. For all the cases, the accumulation of fly ash in Al6061 decreases the thermal conductivity and increases the specific heat carrying capacity of a hybrid composite. Increase in weight percentage of fly ash in Al6061 decreases thermal conductivity and thermal diffusivity respectively.

Due to its high energy concentration, hydrokinetic energy from tidal and rivers flow provides great expectation. One of the effective ways to meet the energy production target is to reduce the installation and maintenance effort arranging turbines in such configuration, known as hydrokinetic turbine array. The performance of array configuration is affected by turbine position and rotational direction. This research provides a comprehensive analysis of the effect of turbine rotational direction and position on the array performance. The experimental study and URANS simulation were carried out to gain deeper information. This previous study proposed 3 side-by-side configurations, i.e. Co-rotating” (Co), “counter-rotating-in” (CtI) and “counter-rotating-out” (CtO) and the current study proposed 2 multi-row configurations, i.e. 3T-A and 3T-B. The comprehensive information is provided. Both experimental and numerical study confirmed that the velocity superposition in the interaction zone gives the constructive effect on turbine performance. All site-by-site configurations is able to enhance farm effectiveness. Co configuration is recommended to install in the resource having unpredictable flow direction. However, the CtI is for canal or river since it has better performance. The study for multi-row configuration shows that the downstream turbine has performance decrement due to the bad effect of the upstream turbine wake.
Regulation of Gliogenesis bylin-32/Atoh1 inCaenorhabditis elegans
Authors: Zhang Albert , Noma Kentaro , Yan Dong
Published: July 2020

The regulation of gliogenesis is a fundamental process for nervous system development, as the appropriate glial number and identity is required for a functional nervous system. To investigate the molecular mechanisms involved in gliogenesis, we used C. elegans as a model and identified the function of the proneural gene lin-32/Atoh1 in gliogenesis. We found that lin-32 functions during embryonic development to negatively regulate the number of AMsh glia. The ectopic AMsh cells at least partially arise from cells originally fated to become CEPsh glia, suggesting that lin-32 is involved in the specification of specific glial subtypes. Moreover, we show that lin-32 acts in parallel with cnd-1/ NeuroD1 and ngn-1/ Neurog1 in negatively regulating an AMsh glia fate. Furthermore, expression of murine Atoh1 fully rescues lin-32 mutant phenotypes, suggesting lin-32/Atoh1 may have a conserved role in glial specification.

My Confession of Prince P. A. Vyazemsky
Authors: Lutsevich Lyudmila
Published: July 2020

My Confession (1829) of P. A. Vyazemsky, one of the most important historical, literary and autobiographical documents of the 19th century, has never been the subject of independent study. Its focus of attention is the period of the Prince’s civil service in Warsaw, which predetermined not only the formation of his ideas of liberalism and constitutionalism, but also the collapse of his career as a civil servant in 1821. The article makes an attempt to identify the main formal-meaningful constants of My Confession. As a result of the study, the immediate motif and reasons for the prince's resort to confession, his addressee, the main goal and discursive practices are identified. The author of the article states that My Confession does not contain religious connotations; its main content is the consistent presentation of events, facts, thoughts, feelings (in the form in which they appear in the mind of the Prince almost a decade later), as well as the exposure of the libels of ill-wishers and the restoration of a good name. It is noted that the general autobiographical confessional strategy of Vyazemsky determines both the author’s repentance of the political “errors” of liberal youth and the exposition / propaganda of liberal views due to active auto-citation; at the same time, the fundamental attitude towards veracity is combined with the so-called “Political correctness” (allowing conscious silence about certain events, facts, persons in order to avoid knowingly lying).
Khivinka by Sergey Durylin: the Poetics of Narration
Authors: Korshunova Evgeniya A.
Published: July 2020

The article analyzes the previously unexplored story of Sergey Durylin Khivinka (the story of a Cossack woman) (1924), written by the author in Chelyabinsk exile. The story is written in a narrative manner inherent in literature of the 1920s. Durylin, who is least oriented towards the Soviet everyday life, who is invisibly and silently arguing with the literary majority, creates an artistic image of a woman of the 19th century descending from common people, a Cossack woman, who was captured by the Khivins, based on historical facts recorded by N. K. Bukharin. The article takes into account the literary sources the author built his work on: A Journey Beyond the Three Seas by Afanasiy Nikitin and The Enchanted Wanderer by N. S. Leskov. The clearly expressed Easter archetype of “A Journey” of the story of Durylin outlines the vector of an axiological path of the heroes — the pilgrimage toward Easter, marked with their return to home. Using the poetics of a tale, the writer draws focus primarily toward a narrative manner of N. S. Leskov with its usual confessional character. On the basis of memoirs, it is stated in the article that the writer’s wife, Irina Alekseevna Komisarova-Durylina, to whom this story is dedicated, became the prototype of Khivinka.
The Idiom “Twice Two is Four” in Russian Literature of the 20th Century
Authors: Shaulov Sergey S.
Published: July 2020

The idiom “twice two is four” along with its variations is seen in the article as a marker of the situation of an “underground man”. In literature of the twentieth century the “underground” in its ethical and philosophical aspects has expanded its meaning, becoming the context of a utopian and antiutopian thought, absorbing the tragic experience of Russian culture after Dostoevsky. Of course, the widespread locution “as sure as twice two is four” does not always point at this variety of meanings, but it can be reached only in combination with the psychological type of the “underground man”. Thus, the image of Stalin in the novel “the First Circle” by Alexander Solzhenitsyn is considered as a variation of the “underground” consciousness. The problems of philosophical, history related to the evolution of this type of consciousness and actualized in this novel, remain important for modern literature. Another version of this philosophical collision is given in Victor Pelevin’s anti-utopian novel “S.N.U.F.F.”. In both of these cases, the situation of the underground person becomes a picture of a psychological and historical catastrophe. The negative development of the analyzed arithmetic formula in Russian literature of the 20th century encourages to look for another pole of tradition outside the “main” cultural domains. One of the variants of a moral escape from the trap of the “underground consciousness” can be found in the poetry of Alexander Bashlachev. The mythopoetical plot of the song “Verka, Nadka, Lyubka” is an exceptional variant of the development of the “underground man” topic. A starting point of the plot is just the formula “twice two is four”. The genre shift from lyricism to allegorical epic gives the poet an opportunity to reconstruct the Easter ideal of Russian culture, even if in a tragic and provocative form, close to the tradition of Russian foolishness for Christ.
