Performance enhancement of normal contact ratio gearing system through correction factor
Authors: Ravivarman R. , Palaniradja K. , Prabhu Sekar R.
Published: July 2020

As lined, higher transmission ratio drives system will have uneven stresses in the root region of the pinion and wheel. To enrich this agility of uneven stresses in normal-contact ratio (NCR) gearing system, an enhanced system is desirable to be industrialized. To attain this objective, it is proposed to put on the idea of modifying the correction factor in such a manner that the bending strength of the gearing system is improved. In this work, the correction factor is modified in such a way that the stress in the root region is equalized between the pinion and wheel. This equalization of stresses is carried out by providing a correction factor in three circumstances: in pinion; wheel and both the pinion and the wheel. Henceforth performances of this S+, S0 and S- drives are evaluated in finite element analysis (FEA) and compared for balanced root stresses in parallel shaft spur gearing systems. It is seen that the outcomes gained from the modified drive have enhanced performance than the standard drive.

Published: July 2020

This article presents the simulation analysis on the effectiveness of impact reduction control based magneto-rheological elastomer isolator device (MREID). The MREID is one of the impact isolator devices that produce controllable stiffness by controlling the input current supply to the device coil. In order to control the input current for MREID, a hybrid control structure combining the skyhook and active force control strategy (HYSAFC) is proposed. Firstly, the characteristics of MREID in squeeze mode are investigated systematically in order to establish the relationship between the supply input current to the subsequent force and impact energy within the MREID. The proposed control strategy is used for force tracking control in determining the amount of input current to be applied to the MREID. The desired input current is determined by a current generator that is developed using inverse ANFIS technique which will regulate the current amount based on the desired force and impact energy. The effectiveness of the actively controlled MREID is evaluated using MATLAB simulations by comparing the performance of the MREID controlled by skyhook control against a passive damper. It is shows that the proposed controller recorded better response compared to skyhook controller, thus improving the stability and the effectiveness in controlling the MRE isolator device.

CNC milling strategy of EVA foam with varying hardness to provide a high degree of surface roughness of orthotic shoe insoles is presented in this work. Machining parameters (tool path strategy, spindle speed, feed rate, and step over) in addition to hardness material and wide tolerance insoles were optimized using a hybrid approach of Taguchi-Response Surface Methodology (TM-RSM). The aim of this research was to develop mathematical models and determine the optimum machining parameters which could be applied for the CNC milling of EVA foam as the insoles. Experiments were performed on a CNC milling machine with a standard milling cutter and run under dry coolants. The effects of the six parameters on the average values of surface roughness were initially analyzed by an S/N ratio of TM. Optimal conditions were established from the TM and then used to determine the optimum values in RSM modeling. The final results indicate the significant improvement of percentages (0.24% and 4.13%) in the surface roughness of the insoles obtained with TM-RSM as compared to the TM analysis. It is envisaged the present study would add to the understanding of production for orthotic shoe insoles through CNC milling.
Mixed convection jet impingement cooling of a moving plate
Authors: Saeid N. H. , Busahmin B. S. , Khalid A. A.
Published: July 2020

The mixed convection heat transfer details of a jet impinging targeted a moving heated plate are studied numerically under steady laminar flow conditions. The governing parameters for the present problem are: Reynolds number (Re), Grashof number (Gr), the velocity of the heated plate (U), jet width and distance from the heated plate. The results are presented to show the fluid and heat flow structure at different conditions with fixed width of the jet and fixed distance from the heated plate and different other parameters. It is observed that the bouyancy effects are more obvious at low values of Reynolds number and plate velocity and the forced convection is dominating at high values of Re and U.  At low values of the plate velocity (U/V < 0.5 with Re = 200 and Gr = 1×104) it is observed that the heat transfer is reduced due to the opposing effects of the jet flow and the flow induced by the plate on one side of the plate. However the increase of the plate velocity more than (U/V > 0.5 with Re = 200 and Gr = 1×104) the heat transfer is increased due to the combined effect of the jet flow and the stronger flow induced by the movement of the heated plate.

Published: July 2020

Latent heat storage has shown a great potential in many engineering applications. The utilization of latent heat storage has been extended from small scales to large scales of thermal engineering applications. In food industry, latent heat has been applied in food storage. Another potential application of latent heat storage is to maintain hot beverages at a reasonable drinking temperature for longer periods. In the present work, a numerical calculation was performed to investigate the impact of utilizing encapsulated phase change material PCM on the temperature of hot beverage. The PCM was encapsulated in rings inside the cup. The results showed that the encapsulated PCM reduced the coffee temperature to an acceptable temperature in shorter time. In addition, the PCM maintained the hot beverage temperature at an acceptable drinking temperature for rational time.
Identification of a novel lncRNA (G3R1) regulated by GLIS3 in pancreatic β-cells
Authors: Scoville David W , Gruzdev Artiom , Jetten Anton M
Published: July 2020

Recent advances in high throughput RNA sequencing have revealed that, in addition to messenger RNAs (mRNAs), long non-coding RNAs (lncRNAs) play an important role in the regulation of many cell functions and of organ development. While a number of lncRNAs have been identified in pancreatic islets, their function remains largely undetermined. Here, we identify a novel long ncRNA regulated by the transcription factor GLIS3, which we refer to as GLIS3 regulated 1 (G3R1). This lncRNA was identified for its significant loss of expression in GLIS3 knockout mouse pancreatic islets. G3R1 appears to be specifically expressed in mouse pancreatic β-cells and in a β-cell line (βTC-6). ChIP-seq analysis indicated that GLIS3 and other islet-enriched transcription factors bind near the G3R1 gene, suggesting they directly regulate G3R1 transcription. Similarly, an apparent human homolog of G3R1 displays a similar expression pattern, with additional expression seen in human brain. In order to determine the function of G3R1 in mouse pancreatic β-cells, we utilized CRISPR to develop a knockout mouse where ~80% of G3R1 sequence is deleted. Phenotypic analysis of these mice did not reveal any impairment in β-cell function or glucose regulation, indicating the complexity underlying the study of lncRNA function.
Adiponectin is secreted via caveolin 1-dependent mechanisms in white adipocytes

Published: July 2020

Here we have investigated the role of the protein caveolin 1 (Cav1) and caveolae in the secretion of the white adipocyte hormone adiponectin. Using mouse primary subcutaneous adipocytes genetically depleted of Cav1, we show that the adiponectin secretion, stimulated either adrenergically or by insulin, is abrogated while basal (unstimulated) release of adiponectin is elevated. Adiponectin secretion is similarly affected in wildtype mouse and human adipocytes where the caveolae structure was chemically disrupted. The altered ex vivo secretion in adipocytes isolated from Cav1 null mice is accompanied by lowered serum levels of the high-molecular weight (HMW) form of adiponectin, whereas the total concentration of adiponectin is unaltered. Interestingly, levels of HMW adiponectin are maintained in adipose tissue from Cav1-depleted mice, signifying that a secretory defect is present. The gene expression of key regulatory proteins known to be involved in cAMP/adrenergically triggered adiponectin exocytosis (the beta-3-adrenergic receptor and exchange protein directly activated by cAMP) remains intact in Cav1 null adipocytes. Microscopy and fractionation studies indicate that adiponectin vesicles do not co-localise with Cav1 but that some vesicles are associated with a specific fraction of caveolae. Our studies propose that Cav1 has an important role in secretion of HMW adiponectin, even though adiponectin-containing vesicles are not obviously associated with this protein. We suggest that Cav1, and/or the caveolae domain, is essential for the organisation of signalling pathways involved in the regulation of HMW adiponectin exocytosis, a function that is disrupted in Cav1/caveolae-depleted adipocytes.
Integrins and OPN localize to adhesion complexes during placentation in sheep
Authors: Seo Heewon , Frank James W , Burghardt Robert C , Bazer Fuller W , Johnson Greg A
Published: July 2020

Integrins and OPN are potential mediators of blastocyst attachment to the endometrium to initiate implantation. The goals were to examine the temporal/spatial pattern of expression of integrins at the endometrial–placental interface of sheep encompassing Days 9 through 80 of gestation and determine if OPN co-localizes with integrins. Results show the following: (1) αv, α4, β1, β3 and β5 integrins at the apical surface of endometrial luminal epithelium (LE) from Days 11 through 16 of pregnancy that indicate a role for these integrins during implantation; (2) large, intermittent aggregates of αv, α4, α5, β1 and β5 integrins at the endometrial–placental interface from Days 20 through 55, suggesting adaptation to a localized tissue remodeling stage of placentation; and (3) integrin adhesion complexes (IACs) containing αv, α4, α5, β1 and β5 integrins precisely distribute at the apical surfaces of apposed endometrial LE and chorion along expanses of the interplacentomal endometrial–placental interface between Days 60 and 80 of gestation, suggesting engagement of these integrins with the ECM to stabilize adhesion between endometrial LE and chorion in response to the increasing mechanical stress on this interface by the increasing size of the fetus and volumes of fetal fluids. An advancement is the clear co-localization of OPN and integrins at the endometrial–placental interface throughout gestation in sheep. The comprehensive nature of these results provide evidence that integrins potentially interact with OPN to play key roles in the mechanisms required for implantation and placentation throughout pregnancy in sheep and have implications concerning implantation and placentation in other species.

“Investigation of Talent” in the Debate of Nikolay Dobrolyubov with Fedor Dostoevsky
Authors: Viktorovich Vladimir A.
Published: July 2020

The article analyzes the interpretation of F. M. Dostoevsky’s novel Humiliated and Insulted, proposed by N. A. Dobrolyubov in his essay Downtrodden people (1861). The interpretation of the images of Ivan Petrovich, Prince Valkovsky (an unknown source of his philosophy of egoism, La Rochefoucauld’s Maxims, is introduced into scientific circulation), Nelly is of particular importance, as well as the question posed by the critic about the main character of the novel. The mutual understanding  between the author and the critic comes to an end when their axiologically opposed contexts of understanding come into force. The novel of forgiveness / unforgiveness is interpreted by the critic as the novel of downtroddenness / protest. Having discovered the energy of moral and social nonconformism in Dostoevsky’s novel, Dobrolyubov redirected it from the “native” moral and social channel to his own, social and moral, one. The essay of the critic who created his own version of the novel and writer’s previous works, thereby contributed to the aesthetic and ideological self-determination of Dostoevsky.
Prototype of a Biogas Anaerobic Digester from the Hostel Mess Kitchen Wastes
Authors: Shivam Modi  , Pooja Mahajan
Published: July 2020

Biogas is a non-exhaustible of energy which can be formed from anaerobic fermentation of different types of biodegradable waste such as food waste, plant waste, animal waste sewage and other organic waste. The typical composition of Biogas includes CH4 (50–70%) which is responsible for maximum energy content along with CO2 (25–50%) that can be collected, stored and supplied. Biogas acts as a multipurpose and an eco- friendly sustainable resource of energy which can be utilized for cooking, electricity generation, lightning, heating etc. Biodegradable waste specifically produced in large amounts as a kitchen waste. In modern society, the solid waste per capita has been consistently increasing as of increase in population and change in socio-economic-cultural habits. The biogas production through the kitchen waste thereof provides a solution of disposal of solid waste. The bio gas production through anaerobic degradation pathways can be controlled and enhanced with the help of certain microorganisms and advancements of new technologies. In this research work, an attempt is being made to produce the biogas from kitchen and food waste collected from hostel mess of Chitkara University, Punjab and a novel method of production of microorganism has been also proposed for fast degradation of waste. Under this project, a survey for the estimation of daily production of organic waste from hostel mess has also been done for fifteen day.

BACKGROUND AND OBJECTIVES:

Long-term outcomes of urinary tract infection (UTI) in childhood are not well known. Pregnancy may reveal latent renal damage caused by a UTI because of stress on the kidneys.

METHODS:

Our cohort included adult women with an ultrasonography taken because of a childhood UTI in 1981–1991 (N = 1175). Nine women with a severe congenital kidney malformation or urinary tract obstruction were excluded. Altogether, 260 mothers with a childhood UTI and 500 population-based control mothers without a childhood UTI matched for age, and delivery dates were compared. Our primary end point was the proportion of women with essential or gestational hypertension, preeclampsia, proteinuria, or pyelonephritis during the first pregnancy.

RESULTS:

The pregnancy outcomes of the women with a UTI in childhood did not differ from those of the controls because 105 of 260 (40%) patients met the primary end point compared with 204 of 500 (41%) controls (relative risk [RR] 0.99; 95% confidence interval [CI] 0.82 to 1.2; P = .91). Similarly, there were no significant differences between the 2 groups in essential hypertension (RR 1.0; 95% CI 0.65 to 1.6; P = .92), gestational hypertension (RR 0.93; 95% CI 0.74 to 1.2; P = .54), preeclampsia (RR 1.5; 95% CI 0.91 to 2.5; P = .11), proteinuria (RR 1.2; 95% CI 0.81 to 1.8; P = .36) or pyelonephritis (2 controls and none of the patients; P = .55) during the first pregnancy.

CONCLUSIONS:

Childhood UTIs did not increase the risk of pregnancy-related complications in this controlled population-based study. Thus, UTIs in childhood without severe urinary tract abnormalities appear to have a minimal effect on kidney health in early adulthood.
Hazard of petrochemical pollution of ponds of the “Olexandria” arboretum (Bila Tserkva)
Authors: Bricks Andriy L. , Gavryliuk Ruslan B. , Negoda Yuriy O.
Published: July 2020

Groundwater pollution in the territory of Bila Tserkva aircraft repair plant developed in a latent form for decades, in a similar fashion to the territory of any object of the supply of petroleum products. In the early 90s of the last century, the first signs of this pollution were detected in places of natural drainage of the groundwater flow directed to the ponds cascade of the Western Hollow. It should be noted that this cascade of ponds located on the border of the arboretum protects the rest of the park by absorbing pollutants that migrate from the plant territory. More than 10 years of research of the contaminated area with the goal of designing remediation measures began and continued after that. This project was not implemented in full because of a lack of funds. Based on a comparative analysis of the results of ecological and hydrogeological studies of the past years and a modern survey of the western part of the arboretum “Olexandria” and the adjacent territory of the former aircraft repair plant, it was established that pollution of the pond “Poterchata” continues to this day. Over the past 12 years, the scheme of pollutants incoming into ponds has changed. At first, the main stream of oil pollutants directed to the upper reaches of the beam was considered as very dangerous. Nowadays, perhaps due to the remediation measures taken, this flow seems to be exhausted. However, there were signs of discharge of a polluted underground stream in the lower reaches of the pond “Poterchata”. In the soil samples from wells drilled near the water edge, the oil content is 600-900 mg/kg, and in places of water sampling from ponds, the content of dissolved hydrocarbons varies from 2 to 3 mg/dm3, that is, 60 times higher than the standard for fish farms ponds. It is assumed that LNAPL and contaminated groundwater move towards the cascade of ponds of the Western Hollow not in a continuous stream, but in the form of narrow tongues in places of increased conductivity, which are consistent with the lateral shallow gullies crossing the slope of hollow. It is possible that over time, oil pollution will reach the lower “Rusalka” pond. However, one cannot exclude the assumption of natural attenuation processes, the significance of which increased after the closure of the plant and a decrease in the volume of LNAPL because of its extraction from the subsoil. In order to confirm or refute the assumptions made and decide on the need to protect the ponds of the arboretum it has been planned to equip the observation points in places where we should expect influent of pollutants.

Published: July 2020

The article is devoted to the petrogeochemical features of Neogene collision volcanism in the central part of the Lesser Caucasus within Azerbaijan. The main goal of the study is to determine the thermodynamic conditions for the formation of Neogene volcanism in the central part of the Lesser Caucasus using the available petrogeochemical material. Using factor analysis, as well as the “IGPET”, “MINPET”, “Petrolog-3” programs, material balance calculations were performed that simulate the phenocryst fractionation process, the crystallization temperature, pressure, and figurative nature of the rock-forming minerals of the formation rocks were calculated. It was determined that at the early and middle stages of crystallization of the rocks of the andesite-dacite-rhyolite formation, the fractionation of amphibole played an important role in the formation of subsequent differentiates. Based on computer simulation, it was revealed that rocks of the andesite-dacite-rhyolite formation were formed by fractional crystallization of the initial high-alumina basaltic magma of high alkalinity in the intermediate magma foci. The calculations of the balance of the substance, simulating the process of fractionation of phenocrysts, as well as magnetite, confirmed the possibility of obtaining rock compositions from andesites to rhyolites as a result of this process. In this case, the process of crystallization differentiation was accompanied by processes of contamination, hybridism and mixing. Based on the geochemical features of rare and rare-earth elements, changes in their ratios, the nature of the mantle source and the type of fractionation process are determined. It was revealed that the enrichment of formation rocks by light rare earths, as well as by many incoherent elements, is associated with the evolution of enriched mantle material. Under high water pressure, as a result of the fractionation of olivine and pyroxene, high-alumina basalts are formed from primary high-magnesian magma, which can be considered parental magma. It was established that, in contrast to the elevated Transcaucasian zone in the more lowered East Caucasus, under conditions of increased fluid pressure and reduced temperature, the melt underwent fractional crystallization in the intermediate centers, being enriched with alkaline, large-ion lithophilic elements, light REEs, etc. This is evidenced by the presence of large crystals of feldspars, the contamination of these minerals by numerous crystals of biotite, magnetite, several generations of these minerals, zonality, as well as the presence of related “water” inclusions, such as hornblendites, hornblende gabbro, etc. The physicochemical conditions for the formation of Neogene volcanic rocks of the Lesser Caucasus are determined.
Dynamics and geographical structure of inbound tourism in political transit countries: case of Ukraine
Authors: Lozynskyy Roman M. , Kushniruk Halina V.
Published: July 2020

Ukraine is an important component of the world market for inbound tourism. From the beginning of the twentieth century in some years it was included in the list of the world leading tourist countries in terms of international tourist arrivals. To study modern trends in the development of inbound tourism in Ukraine, during the period of independence, the concept of tourist transit, developed by D. Hill, is applied. It is а part of the wider concept of political and economic transit, well known in the social sciences. The indicators of dynamics of tourist arrivals, incomes from incoming tourism and its geographical structure analyzed in the article indicate incompleteness of tourist transit in Ukraine. Tourist arrivals in Ukraine are more vulnerable to economic and political crises compared with developed countries. Incomes from foreign tourism are an order of magnitude lower. The share of several neighboring countries – Moldova, Belarus, Russia, Poland, Romania, and Hungary – in the geographical structure of the inbound tourists is too high. Accordingly, the index of geographical concentration of inbound tourism is considerably higher than the optimal one; that is the market of inbound tourism in Ukraine is not sufficiently diversified. The development of tourism is negatively affected by the unsettled military conflict in the eastern part of the country. Some indicators of the development of inbound tourism, in particular, its excessive dependence on Russia by 2014, too high share in the structure of arrivals of tourists from countries that were a part of the former USSR, bring Ukraine closer to post-colonial countries. For the sustainable development of inbound tourism in Ukraine, it is necessary to continue the democratic reforms in order to complete the political transit, to overcome finally the consequences of the domination of the communist authoritarian regime. Also, important tasks are the settlement of the political conflict in the East, the improvement of the tourism policy and the improvement of branding of the national tourism product, the creation of competitive niche tourism products, as well as the improvement of the quality of tourist services. If these tasks are not fulfilled, foreign tourism in Ukraine will enter the stage of stagnation.

Ethiopia's Lalibäla and the fall of Jerusalem 1187
Authors: Van Donzel Emeri
Published: July 2020

Although there is no conclusive proof that the fall of Jerusalem in 1187 was not the main reason for hewing the churches at Lalibäla out of the rocks, there seem to be enough indications that the incentive for the enterprise is to be looked for in the internal politics in Ethiopia at the turn of the XIIIth century. The fact that the relations with the most important Muslim power of the time were rather friendly, in any case not hostile, may corroborate this view.ATTENTION: Due to copy-right no online publication is provided.
L'Epistola 70 di Cipriano di Cartagine in versione etiopica
Authors: Bausi Alessandro
Published: July 2020

Ethiopic literary tradition numbers hagiographical and magical texts centred on the legendary figure of St. Cyprian the magician, but no Ethiopic version of St. Cyprian’s (bishop of Carthage, † 258 A.D.) works has so far been registered in the current literature. This contribution is devoted to the edition, translation, and philological analysis of the only authentically cyprianic text preserved in Ethiopic: Epistula 70. This «synodal epistle» (254 or 255 A.D.) originates from 3rd century baptismal controversies: Cyprian maintains that it is necessary that all who come from heresy must receive full baptism. Besides the Latin original text, Epistula 70 is preserved in a Greek translation (inserted in Zonara’s and Balsamon’s canonical collections), but no oriental version exists, except for the Ethiopic one. Epistula 70 is preserved in 5 mss. of the Ethiopic Sēnodos: EMML 1843, ff. 58rb–60rb; EMML 2430, ff. 42rc–43rb; BN Zotenberg 121 [Éth. 95], ff. 78va–79va; BAV, Borgiano etiopico 2, ff. 173rb–174vb; Uppsala, University library, O Etiop. 39, ff. 121ra–122rc; the 5 mss. can be classified according to a clear stemma codicum and all of them have been used in the present edition. J.M. Wansleben identified Epistula 70 in 1671, but his discovery has remained neglected till now. Concerning the Vorlage of the Ethiopic translation, there are some clues to a direct dependence on a Greek version, which could be older than that preserved in the byzantine canonical collections.
Madamato and Colonial Concubinage in Ethiopia: A Comparative Perspective
Authors: Trento Giovanna
Published: July 2020

Colonial concubinage in Ethiopia during the Italian occupation (1936–1941) has not been deeply studied yet. This article explores the peculiarities of the so-called madamato – that was banned under Fascism in 1937 but developed despite the racist legislation – by firstly comparing its practices in Ethiopia with that which took place from the late Nineteenth century in Eritrea. Indeed, on the Eritrean case a small body of significant literature already exists. In addition, by relying on both written and oral sources, this article highlights the relevance of local agency, the influence of “traditional” customs and religion, and the role played by Ethiopian women in the impact of and the shape taken by colonial concubinage in Ethiopia. It also points out some continuity between the colonial and post-colonial periods (in terms of social behaviors) and the complex roles played in local societies by Ethiopian-Italians and Eritrean-Italians (including the offspring of relationships based on concubinage). Furthermore, this article highlights that gender relations in the region during Italian rule were also affected by the fact that Italian colonialism in the Horn of Africa influenced to some extent the construction of Italian national identity and self-representation.

Traditional Medicine and Magic According to Some Ethiopian Manuscripts from European Collections
Authors: Burtea Bogdan
Published: July 2020

The present paper is dealing exclusively with medico-magical texts and traditions from a Christian Ethiopian environment. The handbooks and collections of various traditional healers in Ethiopia have played a significant role in the chain of transmission of medical and magical knowledge. This paper will focus on the structure and composition strategy exemplified by four Ethiopian manuscripts (MS Or. 11390 from the British Library, MS Éthiopien 402, 402 and 648 from the Bibliothèque nationale Paris). The analysis shows how the specialist knowledge was transmitted, preserved and reused. Moreover, it sheds some light on the protagonists of this transfer.

100 Jahre Amharisch-Unterricht in Hamburg
Authors: Gerhardt Ludwig
Published: July 2020

The article offers a spirited account of the 100-year-old history of teaching Amharic at the Universität Hamburg. It presents significant turning points in the fortunes of Amharic as a foreign language first taught in the Kolonialinstitut and then at the university, and portrays the people who shaped them, in particular the lectors of Amharic from Ethiopia. The account draws on archival documents interwoven with personal memories.

Elementi romani nella tradizione letterari aksumita
Authors: Lusini Gianfrancesco
Published: July 2020

The presence of literary works of Roman origin or milieu inside the Christian Aksumite tradition allows us to reconstruct the image of the Empire circulating among the Christians of Aksum. An antagonism between Church and State and a mistrust of any form of political and social organization were the basic concepts that works like the “Shepherd” of Hermas and the “Antichrist” of Hyppolitus transmitted to Ethiopian Christianity, particularly its monastic centres. In contrast to this tendency, a literary trend dating back to the ancient core of the “Kebra nagaśt” supported the aspirations of the Aksumite leadership by promoting an image of the Christian Ethiopian king as a hero in the end of the days in keeping with millenarian expectations.
Blau aus der Waschküche: Wege einer Farbe nach Äthiopien
Authors: Marx Annegret
Published: July 2020

In traditional Ethiopian paintings a shining blue is observed. An analysis of four objects from the Museum Haus Völker und Kulturen in St. Augustin shows that they were painted with laundry blue. This substance is of varying composition, and has contained synthetic ultramarine since 1830. Laundry blue was of daily use and carried by travellers and missionaries. It was widely used by painters because of its shining colour and good technical properties. In this article the most likely paths by which synthetic ultramarine could have reached Ethiopia are described. This can be shown to have taken place several decades before 1900, the date that has been hitherto assumed to mark the introduction of synthetic colours. The German Zander was probably the first painter in Ethiopia to decorate a church (Därasge Maryam) with synthetic ultramarine in 1852.

Our reaction to anger also tends to befar more aggressive than usual

Published: July 2020

The important goal in dentistry is to provide best dental care to the patients. Day by day, science is undergoing great revolutions that are leading the humanity towards a new era of dentistry. Nanotechnology is introduced in conventional GIC and resin-modified GIC to improve the mechanical properties of GIC. The development and implementation of composite dental restorative materials rely on a comprehensive understanding of each component of the composite and consideration of methods for changing each component. The need to improve shrinkage properties and wear resistance is obvious for dental composites and a vast number of attempts have been made to accomplish these aims. Based on recent clinical information, it appears that major successes have been achieved in reaching the goal.
UPAYA PENYELESAIAN SENGKETA PADA SEKTOR BISNIS PARIWISATA DI TENGAH PANDEMI COVID 19
Authors: Nasrudin N
Published: July 2020

Tourism is one of the new style industries, which is able to provide rapid economic growth in terms of employment opportunities, income, standard of living and in activating other production sectors in tourist-receiving countries. While business is an activity to make a profit. In running a business, sometimes there are disputes between business actors and other business actors. Sometimes disputes that occur are due to a party defaulting and the other party feels disadvantaged. Broadly speaking, in Indonesia there are two pathways to resolve disputes namely litigation and non-litigation. The Litigation Path is a settlement effort made in the Court, while the non-litigation path is the settlement effort that is carried out outside the court. This study uses a type of library research, then this study uses a normative qualitative approach. The results of this study conclude that business disputes can occur at any time without exception when the outbreak of Covid 19. For example, the tourism business sector whose turnover has now declined dramatically because there are government regulations that require at home and not traveling. The decline in the turnover of the tourism business sector has made companies negligent, such as not paying full salaries to employees and being late in paying taxes. Such events can lead to disputes between companies and individuals. One of the efforts taken in resolving this dispute was mediation, while the mediation used was electronic mediation considering that the Covid 19 pandemic is not yet over.
El árbol que apalabra el mundo: Acercamiento a la poética de Julio César Goyes
Authors: Pineda Mozo Miyer Fernando
Published: July 2020

Julio César Goyes, uno de los poetas fundadores del grupo Si Mañana Despierto, es el árbol que apalabra el mundo; para hacerlo se sumerge en el río de la muerte a través del mito y sus misterios. Su imagen poética devora, semilla el silencio en el lector que habita su obra. El escenario conceptual que respalda este análisis, proviene de parámetros ofrecidos por la hermenéutica de Ricoeur, en lo concerniente a la mediación textual que posibilita procesos de comprensión y de autocomprensión, resuelta a través de lo simbólico; además, se aborda su noción de cuasi-texto: posibilidad de pensar la acción humana como textualidad a interpretar. La importancia de este tipo de reflexiones, radica en la necesaria lectura de los aportes de un grupo literario, cuya génesis es una raíz crítica-creativa desprendida de la tradición poética de MITO.
EL FRAGMENTO Y LA COMPLEJIDAD MUSEOGRÁFICA O cuando la tradición se disfrazó de modernidad
Authors: Zúñiga Muñoz Manuel Antonio
Published: July 2020

La muestra es un producto de apropiación de la investigación doctoral de Ramírez Botero en la cual, tras estudiar la obra de la pintora cartagenera Cecilia Porras, logró poner en contexto la historia para explicar en qué radicó su aporte al arte moderno de Colombia. Para ello, estudió la génesis del actual Museo de Arte Moderno de Cartagena y de la Escuela Superior de Bellas Artes, así como el concepto de “arte moderno” en el periodo hito de 1957-1959. De estudios convencionales donde prevalecen los artistas, Ramírez Botero pasó a uno donde se entretejen más aspectos.

Local inflammatory response to suture material in surgical practice: experimental data
Authors: Akentyeva T. N. , Shishkova D. K. , Burago A. Yu. , Kudryavtseva Yu. A.
Published: July 2020

Objective: to study the effect of various types of suture materials, potentially suitable for cardiovascular surgery, on experimental surgical outcomes. Materials and methods. Polypropylene sutures (Prolene 6/0), titanium nickelide (TiNi) sutures (6/0) and absorbable polydioxanone sutures (Monoplus 6/0) were used in the study. Male Wistar rats were used for in vivo studies. The effect of suture materials on abdominal adhesions was studied. In vivo calcification process was examined, and response of blood components in contact with suture materials was also assessed in vitro. Results. There is a negative inflammatory response to suture materials. The severity of this response depended on the type of material used. Polypropylene sutures demonstrated the most severe inflammatory response provoking massive adhesion formation. In addition, large calcium deposits were found both in the suture area and in the thickness of the biomaterial, stitched with prolene and implanted subcutaneously in the rats. Titanium nickelide sutures showed high hemocompatibility and biocompatibility. The Monoplus sutures caused minimal inflammatory response and provoked calcification of the biomaterial to a lesser degree. Conclusion. The suture material could have significant effects on surgical outcomes and could cause postoperative complications.
Status Ontológico da Teoria do Discurso (TD) em Laclau e Mouffe: Diálogos, Perspectivas Teóricas e Conceitos Básicos
Authors: Marques Marcelo de Souza
Published: July 2020

RESUMO Cada vez mais a Teoria do Discurso (TD) em Laclau e Mouffe tem sido problematizada e mobilizada, enquanto ferramenta teórica, epistemológica e metodológica, em diferentes campos do conhecimento, evidenciando seu caráter interdisciplinar. Contudo, algumas discussões teórico-filosóficas presentes nesta teoria ainda carecem de mais esclarecimentos, pois nem sempre são expostas por Laclau e Mouffe de forma mais desenvolvida. Diante disso, o objetivo deste artigo é retomar alguns elementos centrais que, ao ajudarem a delinear o status ontológico do pensamento laclau-mouffeniano, auxiliam na “localização” da teoria de forma mais ampla, permitindo ao público mais geral acessar algumas de suas principais bases de fundamentação. Com isso, espero contribuir para uma melhor compreensão da TD e de seus conceitos elementares.
