Published: June 2020

The aim of the study was to test the possibility of using carcass measurements and joint tissue composition to predict the half-carcass tissue composition of lambs more accurately. With this purpose in mind, 6 different carcass joints (neck, flank, shoulder, ribs, hind limb, and tail) from 42 Kıvırcık male lambs were dissected. In addition, various carcass characteristics were recorded. When carcass characteristics and measurements were used alone in the prediction equations, accuracy (between 37%–68%) was similar to the equations that included only joint dissections (36%–75%). However, when joint dissection and various carcass traits were combined, half-carcass tissue composition was predicted more accurately (65%–90%) than in measures using either joint dissection or various carcass traits alone. Flank was the most successful predictive joint for prediction of muscle weight, when combined with some carcass traits, while the equation built with hind limb and various carcass traits was most successful for predicting total fat weight. Carcass traits yielded accuracy that was similar to joint dissection results, especially for muscle and total fat weights. Therefore, for these parameters, carcass traits are preferred as this measure is cost-effective, noninvasive, and practical. However, for greater accuracy, joint dissection and various carcass characteristics and measurements should be combined
La grande peur de l’an 2020

Le printemps 2020, marqué par la diffusion en Europe (après l’Asie de l’Est) de la pandémie de Covid-19, constituera, à n’en pas douter, une rupture dans l’organisation et le fonctionnement de nos sociétés, dans de multiples domaines. La France, à peine sortie du confinement au moment où se préparait ce numéro d’été de la revue Futuribles , paiera aussi son tribut à cette pandémie et aux conséquences qui l’ont suivie. Le sujet de la crise du Covid-19 et de ses impacts n’est pas près d’être épuisé, et il intégrera progressivement le contexte général d’analyse de nombreux champs d’études. Il nous est cependant apparu important, en ce début d’été 2020, d’ouvrir un forum, dans nos colonnes, à divers experts pour en évoquer, encore « à chaud », certains aspects, d’ordre économique, social, sanitaire, alimentaire, écologique… C’est Nicolas Berg qui ouvre ce dossier « Covid-19 : causes, impacts et stratégies » par une analyse critique vis-à-vis de la longue imprévoyance de la communauté internationale face au risque pandémique et des réponses apportées qu’il juge, comme d’autres observateurs, trop indiscriminées et souvent disproportionnées. Il souligne les conséquences lourdes et durables de cette épidémie, « un tsunami économique, social et démocratique » qui risque de faire plus de dégâts que ceux que l’on a cherché à éviter, y compris en termes de morbidité et de mortalité. Il plaide pour le retour rapide à une évaluation plus mesurée et régulièrement ajustée du risque, et recommande de tirer rapidement tous les enseignements d’une gestion de crise gouvernée comme jamais par l’émotion.

Un rêve derrière un nuage. Lire le chinois dans le Paris du XIX e siècle
Authors: Fabre Clément
Published: June 2020

Depuis le xvi e siècle, l’étrangeté et la difficulté de la langue chinoise fascinent les missionnaires jésuites comme les savants européens, et cette fascination trouve encore un écho au xx e siècle dans celle qu’un Roland Barthes ou un Henri Michaux vouent à l’idiome du Céleste Empire. Dans cette histoire séculaire, toutefois, le xix e siècle occupe une place à part, où les sinologues parisiens, alors même qu’ils parviennent à maîtriser la langue chinoise mieux que quiconque en Europe jusqu’alors, s’efforcent de distinguer son déchiffrement des lectures ordinaires. Reléguer la langue chinoise hors du registre commun de la lecture permet en effet à la sinologie naissante d’affirmer son monopole sur cette langue en définissant les modalités de son déchiffrement légitime. Qu’a-t-on le droit de lire dans la langue chinoise ? Avec quels outils doit-on aborder un manuscrit chinois ? Comment doit-on le lire, et quelles émotions sa lecture est-elle censée procurer ? Le déchiffrement de la langue chinoise fait ainsi l’objet d’une exceptionnelle théorisation. Ce qui n’empêche pas pour autant des acteurs non sinologues, tels les amateurs d’art et les poètes, de s’obstiner à lire différemment la langue chinoise, et à y lire autre chose – que ce soit la valeur d’un vase chinois ou le secret d’un effet poétique. Le cas de la langue chinoise dans le Paris du xix e siècle permet ainsi d’aborder deux questions largement négligées par l’histoire de la lecture : l’acte de lecture varie-t-il au gré des langues lues ? Et que lit-on dans un texte, hormis son sens ?
Apprentissage de l’aide au sevrage tabagique dans les formations médicales au Liban
Authors: El Kahi Hala , Haddad Fady , Hlais Sani
Published: June 2020

Introduction : Le tabagisme est responsable d’une lourde morbi-mortalité. Cependant, une optimisation de sa prise en charge contribue à la réduction des pathologies qui en découlent. Objectif  : L’objectif de cette étude était de développer, organiser et évaluer une formation basée sur l’approche par compétences (APC) auprès des résidents au Liban leur permettant de savoir agir devant un patient fumeur. Méthodes : La formation a été planifiée en débutant par la détermination des tâches à accomplir et des compétences visées. Une étude descriptive transversale auprès de 16 résidents a relevé leurs besoins éducatifs permettant ainsi la formulation des objectifs pédagogiques. Le moyen d’apprentissage choisi était l’atelier. Une analyse pré/postintervention a permis d’évaluer les progrès. Résultats : L’analyse des besoins a montré un niveau de maîtrise insuffisant dans l’approche du patient fumeur ainsi que l’existence d’obstacles (score « Connaissances générales » : 7,1/10 ; « Pratiques » : 6,5/10 ; « Compétences » : 3,8/10 ; « Obstacles » : 5,6/10). L’analyse pré/postintervention a montré une amélioration significative de tous les scores ainsi qu’une diminution significative des obstacles (score « Connaissances générales » : 9,4/10 ; « Pratiques » : 9,2/10 ; « Compétences » : 8,3/10 ; « Obstacles » : 2,1/10). L’évaluation de l’atelier était nettement favorable. Conclusion : Un atelier basé sur l’APC est efficace en termes d’acquisition des compétences professionnelles nécessaires à l’optimisation de l’aide au sevrage tabagique chez les résidents. Il devrait à ce titre être intégré dans le cursus médical et délivré à tout médecin, a fortiori dans un pays présentant un taux de tabagisme des plus élevés et des politiques antitabac presque inexistantes.
Représentations des acteurs de la mise en œuvre du projet régional de santé dans deux régions
Authors: Bréchat Pierre-Henri , Jourdain Alain
Published: June 2020

Contexte : En France, le projet régional de santé (PRS) constitue la référence des politiques de santé sur les territoires. Il est élaboré en trois grandes étapes : préparation, diagnostic et priorités. Différents acteurs institutionnels y participent : gestionnaires, administrateurs, animateurs de la démocratie et acteurs du terrain médico-social et des soins de première ligne. Comment ces acteurs ont-ils investi les trois étapes de la préparation du PRS ? Objectif : L’objectif de cet article est d’analyser la mise en œuvre du PRS dans deux régions et la représentation que s’en font les acteurs. Méthode : L’analyse de la mise en œuvre du PRS a porté sur la définition du processus de réalisation, le diagnostic, l’identification des problèmes jusqu’à l’élaboration des priorités et des objectifs en prenant en compte les ressources et l’évaluation. Cette analyse a été réalisée dans deux régions de taille moyenne en France entre 2011 et 2015. Résultats : La formulation des problèmes dans les PRS reste assez générale. Les priorités et les objectifs sont peu justifiés. Les ressources et l’évaluation sont peu prises en compte. Nous attribuons ces faiblesses à la difficulté de croiser les représentations administrative, gestionnaire ou démocratique des acteurs du PRS avec les pratiques de soins dans les territoires. Conclusions : Une méthode et un processus intégrant les deux représentations de l’action publique devraient être précisés dans un document établi avant d’engager officiellement la démarche de planification. Une harmonisation de la méthodologie et des termes est nécessaire ainsi que le développement de formations et de recherches.
CT diagnosis of appendiceal intussusception in a middle-aged female
Authors: Miller Jacob L. , Shukla Savya , Baigorri Brian , Tejero Hilda
Published: June 2020

Appendiceal intussusception is rare with an estimated incidence of 0.01%. Although it is infrequently encountered, the few documented cases of this entity have shown it may mimic or indicate an underlying neoplasm when evaluated with colonoscopy. With the abundant use of multi-detector CT and increased utility of CT colonography, awareness of the radiologic findings of this condition has become increasingly important. Appendiceal intussusception, while potentially pathologic in its own right, may mimic or even coexist with other pathologies, both malignant and benign. We present a case of adult appendiceal intussusception without a "lead point" that was successfully diagnosed by CT imaging.
Núcleos litorales informales en la provincia de Santa Cruz de Tenerife (Canarias), Génesis y evolución
Authors: Martín Fernández Carlos S. , Martín Martín Víctor O. , Jerez Darias Luis M.
Published: June 2020

El resultado de la normativa sobre costas en aplicación del mandato constitucional de protección de los bienes de dominio público marítimo terrestre no sólo no ha evitado la degradación del litoral, sino que en los años de mayor intensidad aplicativa ha generado una notable conflictividad social. Un problema que, en el caso de Canarias, por ser territorio insular, pre­senta unas específicas características. En el presente artículo utilizando preferentemente fuentes hemerográficas y entrevistas a vecinos afectados, analizamos la naturaleza del conflicto acaecido en buena parte del litoral canario y constatamos la ausencia en la gestión de un real conocimiento sobre la naturaleza de la ocupación histórica de algunos de sus tramos, así como la alta res­ponsabilidad, presente y pasada, de la administración en el desarrollo de los enclaves litorales, hoy en día en amenaza de derribo.
Puertos y turismo de cruceros en islas del Atlántico medio septentrional (Caribe y Macaronesia)
Authors: González Morales Alejandro , Ramón Ojeda Antonio A.
Published: June 2020

El presente trabajo realiza una aproximación al turismo de cruceros en el Atlántico Medio Septentrional. Se estudian las características de los puertos, rutas y destinos del Caribe y la Macaronesia, estableciendo un análisis comparado e individual de cada ámbito. Se analiza el número de cruceros, su frecuencia, estacionalidad y duración, las principales rutas, los recursos más visitados y también las características de los puertos, de los que se elabora una propuesta tipológica. Se han observado algunas similitudes entre ambos espacios, pero sobre todo existen diferencias, tanto cuantitativas, como cualitativas. Asistimos a una transformación del modelo de turismo de cruceros que es resultado del crecimiento de este segmento, lo que está dando lugar a nuevas formas de utilización del territorio y sus recursos. Los puertos se transforman con rapidez debido a las inversiones en in­fraestructuras, pero su localización es cada vez menos determinante en el diseño de las rutas.
El protocolo “network” aplicado al estudio de los destinos turísticos: el caso de Gijón (España)
Authors: De la Ballina Ballina Francisco Javier
Published: June 2020

La definición del concepto de destino es un asunto muy complejo, dada la necesidad de consenso entre distintos tipos de académicos y de profesionales, pero muy necesaria para poder establecer un marco adecuado de conocimiento orientado a la planificación y a la gestión del turismo. La mayoría de las nuevas propuestas giran en torno a la perspectiva de Red (Network), con intra e interrelaciones entre agentes, atracciones y servicios turísticos, e incluso destinos. El factor experiencia de “segunda generación”, apoyado en el fenómeno de la co-creación, es actualmente considerado el leit motiv para el turista. De acuerdo a tal concepto son los turistas quienes, con las elecciones de recursos y servicios, y con sus movimientos en los territorios, definen realmente un destino como tal, y en sus diferentes facetas. Este trabajo recurre al uso del conocido juego del SmartMax para ofrecer un protocolo empírico de conocimiento, cuantitativo y cualitativo, de un destino turístico. Apoyándose en datos sobre la movilidad de los turistas, y mediante técnicas de análisis multivariable, se consigue identificar los diferentes perfiles de un espacio geográfico como destino turístico, así como el peso relativo de cada uno de ellos: destino único, sede central, destino de circuito y destino de excursionismo. De esta forma se construye una metodología útil para el conocimiento empírico de los destinos turís­ticos, de forma general, e incluso para su aplicación en otros ámbitos del marketing geográfico, en particular.

Authors: Alanbar Maha , Alfarraj Amal , Alghieth Manal
Published: June 2020

In the present era, due to technological advances, the problem of energy consumption has become one of the most important problems for its environmental and economic impact. Educational buildings are one of the highest energy consuming institutions. Therefore, one has to direct the individual and society to reach the ideal usage of energy. One of the possible methods to do that is to prediction energy consumption. This study proposes an energy consumption prediction model using deep learning algorithm. To evaluate its performance, College of Computer (CoC) at Qassim University was selected to analyze the elements in the college that affect high energy consumption and data were collected from the Saudi Electricity Company of daily for 13 years. This research applied Long short term memory (LSTM) technique for medium-term prediction of energy consumption. The performance of the proposed model has been measured by evaluation metrics and achieved low Root mean square error (RMSE) which means higher accuracy of the model compared to relative studies. Consequently, this research provides a recommendation for educational organizations to reach optimal energy consumption.
Finding a Parked Car Location in a Multi-Storey Building without GPS Service
Authors: Fathy Heba , Elbasiony Reda , Faheem Mohamed Talaat
Published: June 2020

This paper introduces a new approach named ‘Find My Parked Car’ to provide the user with the return way for his parked car location in the indoor garage of a multi-storey building where GPS is denied using the acquisition data obtained from the inertial sensors on smart devices such as smartphones. We build up a system that employs Pedestrian Dead-Reckoning Technique (PDR) to track the user inside the building. This approach harness the environment landmarks for floors separation and the PDR paths’ landmarks to enhance them by applying the Kalman Filter. Then we prunes the paths to remove the redundant parts of paths. Finally, we display the paths that guide the user back to his car via an android application. The feature of our approach is to help users returning back to parked car location based only on the available ubiquitous sensors in the new smartphones without any need to have any map or any additional infrastructure support.

Published: June 2020

Now, people all over the world use messengers to communicate with their families and employees at work, schedule meetings, congratulate on holidays, and conduct banking operations using bots built into messengers. However, it is challenging to improve such architectures, as a result of which WhatsApp still does not have Chabot’s, whereas their competitors from Telegram already have them built-in. The essence of this project is to create a messenger that has an optimal ratio of functionality and code processing speed, as well as the ability to improve the architecture without high resource costs quickly. The basic version has features such as registration, logging in with your account, checking whether the user is online, messaging, and hash encoding for secure messaging over the Internet. The result showed a high potential for improving the application architecture in any part of the code within the acceptable level of influence on its other functions, as well as a more stable operation of the application itself in comparison with applications built based on Android or JavaScript. However, it was not possible to achieve a higher code processing speed in comparison with other Android or web applications. A method is designed and implemented to enhance the speed of code processing. The results produced by this proposed method and design has shown enhancement in the speed of code processing for messengers. Compared with other Android or with other web applications messaging systems.

Si l’un des buts de l’histoire de l’art est de mieux comprendre le sens originel des œuvres étudiées, la méthodologie historique est alors une absolue nécessité pour identifier et interpréter les objets produits avant la colonisation. Cet essai s’intéresse aux sculptures en ivoire des XVIIe et XVIIIe siècles, identifiées comme « luso-africaines ». Aussi bien la provenance géographique que l’origine culturelle ou « ethnique » des artistes présumés ont été identifiées de façon erronée. Les mentions géographiques associées à la côte de Haute-Guinée au XVIe siècle ne correspondent pas aux régions actuelles. De même, le terme employé pour identifier la culture des artistes, « Sapes », ne renvoie à aucun groupe social contemporain employant cette appellation.

Published: June 2020

Dispersion is one of the fate processes of oil spill. This research has been carried out on the numerical simulation of the dispersion of crude oil using the model obtained from the work of Hamam (1987). The model was solved with the explicit, implicit and Crank-Nicolson methods of solution of partial differentiation equations with the aid of MATLAB, and the concentration of the crude oil dispersed in water was obtained. The results obtained revealed that the three methods could be used to study the process because the profiles given by all of them were very similar. Also discovered from the investigations carried out was that the concentration of crude oil was decreasing with time for a particular spatial point while, for a particular time, it was increasing along the length of the water body. It was also discovered that experiments would be very necessary in order for the validation of the results obtained from the simulations.

Published: June 2020

Renewable energy sources, such as photovoltaic, fuel cell and wind energy are becoming a sustainable alternative to non-renewable sources like fossil fuel. However, to integrate these energies into the grid, power electronic converters plays major role due to their power conditioning capability, reliability and effectiveness. In this paper, design, modeling and analysis of a DC-DC boost converter with robust controlling technique, fuzzy sliding mode controlling strategy has been developed and a brief comparison has been performed with a sliding mode controller and a clasical PID controller which employed both current and a voltage control loop. The system is designed to achieve a fast dynamic response, zero steady-state error, and satisfactory stability. To realize that a detailed mathematical derivation of sliding mode fuzzy logic controller and a linearized small signal model of the power electronic converter around its DC steady state operating point is performed. Finally, in order to evaluate the designed system, a software simulation based on MATLAB/ Simulink environment is developed and results of the simulation shows the effectiveness of the proposed techniques.

Published: June 2020

The worlds growing population demands more food and creates more waste. Economically viable and environmentally friendly would be to use sewage sludge for agricultural production. There are several limitations for this use – heavy metal content, pathogenic microorganisms, helminths etc.. The different methods of treatment of sewage sludge helps to overcome this problem. The aim of the study is to find the effects of treated sewage sludge on the growth of maize and changes in soil biological activity. Experiments were carried out with dry sewage sludge preparation (SSP) in the such combinations 1) SSP, 2) SSP+PK, 3) SSP+NPK. Controls- loamy soil without additional fertilizer, soil mixed with mineral fertilizer (Kristalon 18:18:18). Maize (Zea mays var. saccharata ‘Elan F1’) was grown. Experiments were arranged in 1L vegetation containers placed in open area with additional watering. Plant growth parameters and soil enzymatic activity was detected. The SSP alone and in combination with potassium and phosphorus fertilizers does not provide the maize with the mineral nutrients in appropriate value, therefore, the combination of SSP with nitrogen containing fertilizers significantly improves plant growth and promotes development. The use of SSP increases the microbiological activity of the soil. This can have a beneficial long-term effect on the mineral nutrition of plants.

Published: June 2020

The most common cinnamoyl anilines are avenanthramides, which are natural antioxidants found in oats. This is a rather uncommon and not well-investigated group of antioxidants. This paper deals with 2-arylidenemalonic acid dianilides – cinnamoyl anilines which are decorated with an additional arylaminocarbonyl moiety at α-position of double bond. The DPPH scavenging activity of the title compounds is slightly lower in comparison to the corresponding cinnamoyl anilines. On the other hand, the title dianilides are more active than cinnamic acid anilides containing an additional carboxylic group in the α-position of double bond.

The histomorphometry of the rabbit bone tissue from the lower jaw was done. Authors hypothesized that local enhancement with biphasic calcium phosphate ceramic materials in the femur trochanter major area increase the trabecular bone volume outside the implantation zone in vivo. Twenty-two California female rabbits were included in this study and were divided into four groups. Four healthy rabbits composed a control group (A group), while other eighteen underwent ovariectomy. Bone defects were created in femur trochanter major region. Sham surgery group (B group) consisted of four female rabbits with osteoporosis and bone defect, but no biomaterials were implanted. In C group (seven rabbits) created defects were filled with granules of biphasic calcium phosphate ceramic (hydroxyapatite (HAP) and tricalcium phosphate (TCP) 30/70); in D group (seven rabbits) defects were filled with the same granules (HAP/TCP 30/70) together with strontium (5% by mass). Twenty-two bone samples were taken from lower jaw premolar region. Trabecular bone area was measured using Image Pro Plus 7 program, where three equal fields (0.975 mm2) of view were at random chosen in all bone samples. Results have shown that the trabecular bone area in A group was 0.201 mm2 (0.176-0.233), which is statistically significantly higher (p <0.0001) than in B group 0.127 mm2 (0.118 – 0.149), C group 0.136 mm2 (0.108 – 0.166) and D group 0.135 mm2 (0.126 – 0.164), respectively. Statistically significant differences between B, C and D groups were not found (p > 0.05).

Published: June 2020

In order to provide good adhesion for natural nail coatings and to avoid loss of adhesion between the substrate and the coating, the mechanical properties of the coating should be close to those of the substrate. Three different mono-functional monomers (HPMA, THFA, THFMA) and one bi-functional monomer (EGDMA) have been added to decrease the viscosity of un-polymerized composition. Optimal monomer concentration was found evaluating monomer concentration effect on viscosity. Polymerized coatings were tested with monomer concentrations of 30% and 40%. The tensile strength properties of the polymerized coatings were determined 24 hours after polymerization. Polymerization T and conversion rate of unsaturated links were also studied to find the best monomer for natural nail coatings.

Authors: Lu Cun , Gu Zheng Jian , Yan Yuan
Published: June 2020

Lithium ion battery is a key component of energy storage system. Accurate and scientific prediction of its Remaining Useful Life (RUL) is an important factor to check the operation of energy storage system is whether reliable. ARIMA is an effective time series prediction processing method, which can be used to calculate battery RUL and its confidence interval. And the more predicted samples, the higher the prediction accuracy. Compared with the empirical model and support vector machine algorithm, the analysis results show that the support vector machine is over-fitting. For two sets of the experimental data, the absolute predictive error of ARIMA algorithm is approximately 1.2%, that of linear model is approximately 1.4%, and that of Verhulst model is approximately 7.5%, which verifies the accuracy of ARIMA time series model in predicting the RUL in long interval.

By changing parameters, results of simulation were obtained, in turn described the effect of uniformity and concentration of AlN. The study mainly focuses on the research of flow velocities of nitrogen and argon gas, the distance from the substrate to the inner tube mouth, the substrate front-back angular height difference, the inner tube diameter, and the substrate thickness. It is discovered through the research: above parameters play a very important role in the crystal growth of AlN film, and there are optimal parameter values. The structure of growth chamber is designed and optimized according to the simulation result. By using the simulation software, experimental costs can be greatly saved, which provides a theoretical basis for the optimal growth process of high quality AlN film, and has a certain guiding role for the actual growth process.

The development of materials for core components which can serve in high temperature corrosive environments for a long service time is crucial to realize high efficiency and high-burnup operation of advanced nuclear reactors. Alumina forming austenitic (AFA) alloy is a kind of promising materials with improved corrosion resistance as well as strength at elevated temperature. The progress on the composition design and characterization of AFA alloys are reviewed in this work for evaluation their potential applications in advanced nuclear reactors. AFA alloys without the addition of carbon have been fabricated. Microstructures were observed by SEM and TEM. Mechanical properties were measured at room temperature and high temperature.

Authors: Socrates Kalai , Gopalakrishna B. V.
Published: June 2020

Development of Micro, Small and Medium Enterprise (MSME) sector is the most apt means of encashing the demographic dividend of India in promoting economic growth, employment generation and inclusive growth. In this endeavour, the Indian government periodically brings out appropriate support measures in the form of policies and programmes. Though many studies have been undertaken by various stakeholders in the past on myriad issues such as credit, marketing, skill development, sickness, export, technology infusion related to MSME sector, the appropriateness and objectives of policies and schemes has not been addressed. This paper attempts to examine the utility of schemes from an enterprise life cycle perspective and to identify any impending interventions needed at any particular stage of an enterprise lifecycle model. It argues that available support measures are insufficient to address the needs of exit stages and also suggests further interventions required for the holistic development of this sector.
Transition Times. Supporting the Child and Adolescent’s Transitions in Pediatric Condition
Authors: Ped S.I.P.
Published: June 2020

Preface: When it comes to transitions, we usually think of important progressions, momentous historical events, peoples’ unforgettable memories, or significant changes in the individual’s life. More rarely, we refer to the feature of simplicity. The Second International Congress of the Italian Society of Pediatric Psychology, in order to focus on and open a debate about the evolutionary transitions in pediatric conditions, emphasised simplicity as essentiality, repeatability, reproducibility and comprehensibility of these progressions [...].
The importance of monitoring vergence eye movements for solutions using virtual technologies
Authors: Piszczek Marek , Pomianek Mateusz , Maciejewski Marcin , Jodłowski Leon , Krukowski Piotr
Published: June 2020

Eyesight monitoring systems are of particular interest to virtual technology research teams and concern mainly three key aspects: physiological, technical and functional. The first one is to solve the so-called conflict of vergence and accommodation. In contrast to typical gaming applications, e.g. vision therapy requires the ability to smoothly transfer attention between the points of near and far. The technical aspect is primarily the search for new measurement methods, which is particularly important in the case of mobile goggles with limited computing capabilities of the processor. The last aspect concerns the possibility of creating effective HMI (Human Machine Interface) solutions. Full Text: PDF ReferencesJ. D.

Authors: Gawlikowski Maciej , Kurtyka Przemysław , Zalewski Jerzy , Zarwańska-Doffek Magda , Kapis Artur
Published: June 2020

In order to avoid blood clotting, in the second generation of rotary blood pumps the impeller is suspended without mechanical bearing, using balance of magnetic and hydrodynamic forces. Reaching single tens of microns gap between pump housing and impeller is crucial for level of blood traumatization by the pump. In this paper we would like to present the method of physical measurement of this gap on a running pump with the use of commercial fiber-optic proximity sensor on the example of Polish rotary blood pump ReligaHeart ROT. We also discussed technical requirements of the construction of laboratory stand. Full Text: PDF ReferencesS.

Replenishing the Odyssey: Margaret Atwood’s and John Barth’s Postmodern Epics
Authors: Aćamović Bojana
Published: June 2020

The paper focuses on Margaret Atwood’s novel The Penelopiad and John Barth’s short stories “Menelaiad” and “Anonymiad,” comparing the approaches of the two authors in their postmodernist retellings of Homer’s Odyssey. Both Atwood and Barth base their narratives on minor episodes from this epic, with its less prominent or unnamed characters assuming the roles of the narrators. Using different postmodernist techniques, the authors experiment with the form and content of the narration, combine different genres, and demythologize the situations and characters. In their re-evaluations and reinterpretations of the Odyssey, they create works which epitomize Barth’s notion of postmodernist fiction as a literature of replenishment. The comparative analysis presented in this paper aims to highlight the ways in which Atwood and Barth challenge the old and add new perspectives on Homer’s epic, at the same time confirming its relevance in the postmodern context.
Preludes and Fugues op. 82 by Nikolai Kapustin
Authors: Daugulis Ēvalds
Published: June 2020

The early 20th century witnessed growing interest in the Baroque polyphony genres: prelude and fugue in jazz. Preludes and fugues op. 82 (1997) by the Russian composer Nikolai Kapustin are particularly interesting. The way he integrates the expression of classical music and the specificity of jazz music is very original.

Slovenska muzikologija: Kratek prelet po zgodovini
Authors: Udovič Boštjan
Published: June 2020

Slovenska muzikologija Matjaža Barba, četudi obljublja le kratek prelet, je bistveno več kot le to. Je očrt tega, kar se je s slovensko muzikologijo v zadnjih 800 letih dogajalo, hkrati pa je tudi izjemen vir podatkov in zanimivih dejstev, ki so bila do sedaj malo poznana. Avtor že v predgovoru napiše, da se njegova razprava ne osredotoča na muzikologijo z vidika točke nič (tj. njeno umestitvijo med sedem muz Filozofske fakultete), ampak da želi preučiti njene izvire. Začne v 14. stoletju, pri cistercijanih, v Stični, centru sveta za nastajajoči osnutek slovenskega naroda.
