The relevance of context in musicological interpretation. Hermeneutical applications on certain Romanian writings and works
Authors: Vasiliu Laura-Otilia
Published: May 2022

We have been perceiving ever more acutely for the past two decades a major change in the vision and musicological style in the Romanian language: language analysis and historiographic research have slid onto a secondary plane, while the commentary of the work, of its interpretation and the characterisation of the style, determined by the social, political, biographical, artistic factors, by the means of expression of the time focus researchers’ interest increasingly. The history of contemporary musicology recognises the moment of change of the thinking paradigm in the 1980s writings belonging to Joseph Kerman: the article How we got into Analysis, and How to Get Out and the volume Contemplating Music. The author criticises the formalism and positivism which define musicology, identified with musical analysis, reveals its ideological nature, as the relation between analysis and organicity is the leading ideology. The American musicologist pleads for a more cultural form of musical criticism, supported by the exposure of the context and of the sources of the work objectified. According to Kerman, musicology had become more discoursively-critical and less positivist (so-called scientific), being more preoccupated with interpretation than with information on the writing details and historical data; it had reconquered its interdisciplinary valences and envelopped all musical genres. Analysing the effects of this direction on the Romanian musicological discourse, we do two case studies: 1. the recent collective work Noi istorii ale muzicii românești [New histories of Romanian types of music], coordinated by Valentina Sandu-Dediu and Nicolae Gheorghiță in the direction of emphasising and/or cancelling the effects of (nationalistic, socialist-realist) ideology on the value judgement of the anthologised musical and creative phenomena; 2. the musical comedy Amorul doctor [Dr. Love] by Pascal Bentoiu, regarded from the perspective of the relation between the artistic value and the cultural trajectory broken by the obscurity of Romanian society in the first half of the 1960 decade.
Schubert’s “Tenth”: an Interpretation Between Construction and Restitution
Authors: Mogoşan Iulia
Published: May 2022

In Franz Schubert’s creation the fragment takes on various forms of manifestation, ranging from the fragmentary reception of an already constituted piece to the fragmentary notation, in the form of a sketch, of a work that has not yet been completed. A special place belongs to the Tenth Symphony in D major, D 936A, by Schubert, left unfinished; we received it as a sketch, in a convolute, together with two other unfinished symphonies in the same key: D 615 and D 708A. The present study aims to expose three artistic interpretations of these sketches, materialized in completed musical works, with a distinct approach. The intention of the British composer and conductor Brian Newbould was to finish the symphony in the way that Schubert himself would have done, anchoring the musical ideas from the sketches in the composer’s style. Peter Gülke approached the sketches through the eyes of the researcher and the analyst, with the intention of obtaining their most accurate and authentic reproduction, emphasizing the materialization of some of Schubert’s possible intentions. Finally, Luciano Berio manages in Rendering to musically render the sketches per se, imagining a musical fresco where the concrete musical ideas, written by Schubert, are deliberately mixed with the provisional character of the manuscript.
Speech melodiesand “pinning down” the present in essays by Leoš Janáček and Milan Kundera
Authors: Dumitriu Leonard
Published: May 2022

I ask myself the question: can those who compose music be called interpreters? Not of their own work but of the sonorities they imagine while writing. When composers take over (note on staves or record with technical means) sonorities from the environment, which they then use in their works, are they or not interpreters, in the sense of translating what they hear? Should we only mention Vivaldi and Haydn or, closer to us, Messiaen and Stockhausen, composers of all times have used, translated, interpreted the sounds of nature in their works. That is what the Czech Leoš Janáček does also, only that, by registering ambiental sonorities, he has a further goal, unlike the others: pinning down the present time. This idea is revolutionary in music, so it has drawn many researchers’ attention. A privilege of music, interpretation wears in literature the coat of exegesis. A great contemporary thinker, Milan Kundera is the author of the essayTestaments betrayed, in which he compares literature with music, having as references, among other writers, Hemingway and Kafka, which he joins with the great composers Stravinsky and Janáček. Fascinated by his fellow citizen’s musical-ontological concept, he dedicates the fifth part of the study to him, entitledÁ la recherche du présent perdu. The study presents the way in which Janáček pins down the past in an own essay,Smetanova dcera(Smetana’s daughter), where he uses his renownednápěvky mluvy(speech melodies). The result is amazing: through the daughter’s voice, one seems to hear the father, the great Bedřich Smetana’s voice in a fragment of life resurrected after time has passed. Kundera asks questions and formulates answers, interpreting, translating Janáček’s concept. This work does not interpret, but brings to the knowledge of the interested musicians aspects which, although belonging to renowned Czech intellectuals, enrich and embellish the spirituality of the world.
Nikolai Myaskovsky – 140th birth anniversary. Rediscovering the composer in the present times
Authors: Balan Mihaela-Georgiana
Published: May 2022

On the occasion of the 140th anniversary of composer Nikolai Myaskovsky’s birth, in the spring of 2021, in the city of Ekaterinburg there took place the Myaskovsky Dialogues festival dedicated entirely to the Russian composer, being one of the few musical events with a musical programme based on his works. Known as the “father” of the Soviet symphony, Nikolai Myaskovsky was one of the pillars of resistance in Russian music culture in the first half of the 20th century, managing to maintain a stylistic balance between traditional genres, harmonic language with innovative tendencies, ideas promoted within the new political system and a neutral way of integrating communist ideals musically. Although his contemporaries perceived him with respect and consideration, N. Myaskovsky was discredited after the tensions and political events of 1948, entering a shadow zone during the Cold War, until the fall of the Iron Curtain. Therefore, it was only in the last three decades that he was rediscovered in the music world, due to the interest given to his works by well-known conductors such as E. Svetlanov, V. Gergiev, V. Petrenko, V. Jurowski. In this paper, our aim is to accomplish a historical perspective on N. Myaskovsky’s rediscovery and his approach in concert programs, records, reviews, chronicles, articles, musicological studies, papers and volumes from the 1970s to the present.
Ștefan Angi – the encyclopaedic musicologist
Authors: Iaţeşen Loredana
Published: May 2022

On 2 October 2021 we celebrate one year since the distinguished Hungarian aesthetician, philosopher, musicologist and professor Ștefan Angi from Cluj-Napoca passed away, an opportunity to meditate on this encyclopaedic researcher’s outstanding scientific work. If we go through the studies published in specialised journals (Lucrări de muzicologie [Musicology Papers], Muzica [Music] Journal) or books Muzică și estetică [Music and aesthetics] (1975), Muzicalitatea esteticului [The musicality of aesthetics] (2001), Modele al frumosului musical [Models of musical beauty] (2003), Prelegeri de estetică muzicală [Lectures on musical aesthetics] (2004 – two volumes and four tomes), De la valoare la semnificație [From value to meaning] (2005), Fotografii la minut din atelierele compozitorilor clujeni [Instant photographs from composers’ workshops in Cluj-Napoca] (2008), Site de in.

Eseuri [Trifles. Essays] (2018), we observe that his lordship fundamentally contributed to various fields of music research: aesthetics, stylistics, rhetoric, musicology. Starting from the published confessions of those who knew him (Cristina Șuteu, Gânduri, Cuvinte, Fapte. Dialog cu Ștefan Angi [Thoughts, Words, Acts. Dialogue with Ștefan Angi], interview in Actualitatea Muzicală [Music news], 2016; Pavel Pușcaș, Ștefan Angi - Hominaticum Magistri – portrait in Muzica [Music] Journal, 2021), we will attempt to comment on some of the volumes of studies or according to the genre of the monograph, in order to emphasize particular features of the musicological writings of researcher Ștefan Angi.
Innovative Aspects of the Modern Concerto (extravagant compositional models of the 20th century)
Authors: Coroiu Petruta Maria
Published: May 2022

The instrumental concerto remains one of the most appreciated genres – both by the general public and by virtuoso interpreters – all throughout its existence, including the 20th century. The century of acute modernity saw a re-evaluation of all the musical forms and genres, resulting in novel challenges, solved in unexpected ways by the great composers of the time. This paper aims to provide a summary of the evolution of the concerto in the music of the 20th century, highlighting certain elements of originality, extravagant compositions which go beyond the principles of musical creation.
Manuscript 105 from the “Dumitru Stăniloae” Ecumenical Library of the Metropolitan Church of Moldova and Bucovina in Iasi - an exemplary document of adapting chants to Romanian in Moldova
Authors: Dănilă Irina Zamfira
Published: May 2022

Ms 105 from the “Dumitru Stăniloae” Ecumenical Library is an extensive Chrysantean Anthologhion, consisting of 236 leaves, written in Romanian with Cyrillic characters by copyist Hariton Vasiliu from Horaita Monastery (Neamt County), between 1857-1879. The chant content is specific to the musical collection this codex belongs to, namely the service of Vespers, Matins, and the Divine Liturgy, freely organized in the manuscript; for this reason, the typical ritual order could not be observed. The musical sources of Ms. 105 are exclusively repertoire collections in the Romanian language, mainly the psaltic prints circulated during that period (about 50% of the total). Their composers are initiators of the implementation of the Chrysantine reform in the Romanian Principalities: Macarie the Hieromonk, Anton Pann, Nectarie Frimu, Dimitrie Suceveanu – they were all important personalities who, through their works, contributed significantly to the replacement of church chanting in Greek with chanting in the “mother tongue” (i.e. Romanian). The other set of chants in Ms. 105 (50% of the total) are, however, from local manuscript sources and are mainly composed by unknown musicians.
Sacred Music in Igor Stravinsky’s work. Symphony of Psalms
Authors: Farcaş Viviana
Published: May 2022

Researching the music of the Russian composer Igor Stravinsky, devoutness is not the first attribute that I have offered it. He has remained in collective memory rather as a music revolutionary, not at all a pious spirit, bent towards divinity. The modernism of his works, the tendencies that he was the first to impose but especially the scandal that chaperoned him ever since the 1913 premiere of the ballet The Rite of Spring, all these have imposed him as a “rebel” of music in the early 20th century. The composer nevertheless claimed that his music was not modern but traditional. The order and discipline which constituted the pillars of his compositions go hand in hand with his claim, the return to tradition and his love for the ancient leading audiences towards the discovery of his mystical, religious side. A far too little explored direction in that period laden with marked social and cultural events was the composition of religious music. Too few of Stravinsky’s opera were inspired from sources of this nature – this is exactly why the discovery of and finding their meanings is important. One of the representative opera of this compositional direction is represented by Symphony of Psalms, considered to be a masterpiece placed in Stravinsky’s neoclassical compositional period. The work wanted to be a return to Christian values through a musical language adapted to the times, the music being led in the spirit of the Gregorian chant, simply, to which a text in the Latin language was added. The lines of the psalms chosen in order to be capitalised on underline his predilection for the complexity of religious feelings, departing from humble imploration to glorification. Thus, although this work firstly reflects a personal religious experience, at the same time it suggests the unbounded expression of constancy in faith of a community, which seems to participate in a collective prayer.
Improvised musical performance as conversational language in jazz
Authors: Campău Elisabeta Firtescu
Published: May 2022

Musical interpretation, in the form of the act of spontaneous composition, defined jazz throughout its stylistic evolution. Unlike other serious music, jazz has crystallised mainly due to the creative act of musical interpretation and less to the process of written musical construction. Within this cerebral musical genre, the act of performing took over as the fundamental role in the artistic communication between jazz musicians and audience but it especially took the form of an interrelation in the collective musical interpretation. The act of musical improvisation, in terms of jazz, is controlled by certain stylistic parameters, associated with form, phrasing and timbre, constantly relating to the harmonic, rhythmic and melodic planes. The standardisation of these parameters transformed jazz into a conversational musical language, which allows constant and organised communication between musicians through the phenomenon ofinterplay(the interaction of performers during the collective interpretive act). The principles ofinterplayare also integrated in the solo interpretation, especially in the case of pianists, who always improvise referring to the context and the relationship created between the accompaniment and the melodic plane. At the same time, just like verbal communication, mastering the jazz language involves reaching the level of free speech, with a spontaneous and contextual expression. This freedom of artistic expression involves the assimilation of the jazz language, creating a personal vocabulary and its use as a means of constructing authentic (spontaneously created) and eloquent musical discourses. Jazz language cannot be assimilated only through individual study, as is possible in the serious music of European tradition. The study and improvement of jazz musicians constantly depends on artistic socialisation and musical conversation. Jazz is a musical genre in continuous transformation, due to the fact that it is definitely more of an act of interpretation than of a compositional one. Jazz imposed musical interpretation as having the same contribution of creation with the compositional act, in terms of stylistic definition and crystallisation of an elaborated musical current or genre.
Study of subjective and objective quality assessment of infrared compressed images
Authors: Zelmati Omar , Bondžulić Boban , Pavlović Boban , Tot Ivan , Merrouche Saad
Published: May 2022

Given the lack of accessible infrared compressed images’ benchmarks annotated by human subjects, this work presents a new database with the aim of studying both subjective and objective image quality assessment (IQA) on compressed long wavelength infrared (LWIR) images. The database contains 20 reference (pristine) images and 200 distorted (degraded) images obtained by application of the most known compression algorithms used in multimedia and communication fields, namely: JPEG and JPEG-2000. Each compressed image is evaluated by 31 subjects having different levels of experience in LWIR images. Mean opinion scores (MOS) and natural scene statistics (NSS) of pristine and compressed images are elaborated to study the performance of the database. Five analyses are conducted on collected images and subjective scores, namely: analysis by compression type, analysis by file size, analysis by reference image, analysis by quality level and analysis by subject. Moreover, a wide set of objective IQA metrics is applied on the images and the obtained scores are compared with the collected subjective scores. Results show that objective IQA measures correlate with human subjective results with a degree of agreement up to 95 %, so this benchmark is promising to improve existing and develop new IQA measures for compressed LWIR images. Thanks to a real-world surveillance original images based on which we analyze how image compression and quality level affect the quality of compressed images, this database is primarily suitable for (military and civilian) surveillance applications. The database is accessible via the link: https://github.com/azedomar/compressed-LWIR-images-IQA-database. As a follow-up to this work, an extension of the database is underway to study other types of distortion in addition to compression.
Smart DTC algorithm with automatic torque ripple adjustment
Authors: Rosić Marko , Koprivica Branko , Bjekić Miroslav
Published: May 2022

The paper presents a direct torque control method with possibilities of automatic algorithm modification in terms of torque ripple reduction. The algorithm is based on the conventional switching table with an arbitrary number of discretized voltage levels allowing higher space-voltage resolution and consequently lower torque ripple. The number of available voltage levels can be easily changed and subsequently torque ripple reduced without the need to modify the conventional switching table. Appropriate algorithm modifications leading to torque ripple reduction are automatized, making this kind of control method simple, effective, and suitable for upcoming smart drives in the rapidly growing industry 4.0. Selective back electromotive force compensation can also be part of automatization with the aim to improve the drive dynamics. Experimental validation presented in the paper confirms improvements in torque ripple reduction retaining the simple and time-effective control structure of the induction machine DTC drive.
Decentralized controlled charging and vehicle-to-grid solution for voltage regulation in low voltage distribution systems
Authors: Zdraveski Vasko , Angelov Jordanco , Krstevski Petar , Mateska Aleksandra Krkoleva , Vuletic Jovica , Todorovski Mirko
Published: May 2022

This paper offers affordable controlled charging and a vehicle-to-grid solution that uses a non-smart power meter. Additional communication infrastructure in the low-voltage distribution network is not needed. Ladder logic control is developed to be easily implemented by any commercial programmable logic controller. The voltage values measured by the power meter and electric vehicle battery state of charge are the decision variables. A validity check based on the Monte Carlo method is conducted to test the effectiveness of the proposed solution. Electric vehicle charging requirements are simulated based on travel surveys. The results demonstrate the effectiveness of the proposed solution. The voltage level is kept within acceptable limits according to the power quality standard EN50160. One may argue that there is a mismatch between the rate of penetration of electric vehicles and the level of smart grid implementation, especially in developing countries with higher rates of wealth inequality. Therefore, the methodology presented in this paper can be seen as an affordable mid-way solution that will help distribution system operators in developing countries prepare for higher penetration levels of EVs.
Multi-UAV integrated HetNet for maximum coverage in disaster management
Authors: Khan Amina , Gupta Sumeet , Gupta Sachin Kumar
Published: May 2022

This article presents a practical method for the 3D placement of a group of HetNet of unmanned aerial vehicles (UAV)-mounted base station (mBS) to offer maximum wireless connectivity and coverage for terrestrial users in a particular region. There are two ways to solve this issue. First, the ideal flying height for each UAV is determined based on the transmit power of the UAV, which offers the maximum ground coverage radius. Depending on their ideal flying altitudes and transmitting power, UAVs are divided into several categories. Given a collection of UAVs, the proposed approach identifies an optimum subset of the available UAVs and places them optimally in 3D to offer maximum coverage of the network for a particular area on the terrestrial ground while using the least amount of power. The results of the simulations show that the suggested approach is effective, and they also give important visions about the behavior of the HetNet supported UAVmBS cell subnetworks.
Probabilistic three-phase power flow in a distribution system applying the pseudo-inverse and cumulant method
Authors: Bogovič Jerneja , Pantoš Miloš
Published: May 2022

A new, analytical approach using the cumulant method is proposed for the three-phase probabilistic power-flow (PPF) analysis. The approach to forming the sensitivity matrix is based on quantifying the pseudo-inverse instead of the inverse jacobian matrix, since it is commonly singular in a distribution power network. The results are compared with those obtained using the point-estimate method (PEM) and the Monte Carlo (MC) method, which is a commonly used reference method for the PPF analysis in a distribution power network.
Spectral and energy efficiency trade-off in massive MIMO systems using multi-objective bat algorithm
Authors: Gül Burak Kürşat , Taşpınar Necmi
Published: May 2022

The rise in the usage of wireless communication increases the cellular communication by the same rate. With the continuation of this situation, the density in data traffic has the potential to cause problems in the near future. Coping with spectral efficiency-energy efficiency trade-off using massive MIMO systems is considered to be a reasonable solution to this problem. In this paper, cellular communication simulations were performed in cases with different number of users, number of antennas and transmission power of massive MIMO systems and then non-dominated solutions are determined. Multi-objective bat algorithm has been used to make this process much shorter. At last stage, performance of this algorithm is compared with various intelligent optimization algorithms and with ideal non-dominated solutions. When the algorithms are compared with each other, it is seen that multi-objective bat algorithm has the best performance among them.
Observability, controllability and stability of a nonlinear RLC circuit in form of a Duffing oscillator by means of theoretical mechanical approach
Authors: Civelek Cem
Published: May 2022

In this research article, observability, controllability and stability of a nonlinear RLC circuit with a nonlinear capacitor is investigated as a Duffing oscillator beginning with the dissipative equations of generalized motion using Lagrange-dissipative model ({L, D} -model briefly). The force related to the potential energy, equilibria, and their well known stability properties are given using state space approach. Prerequisite that the condition for a Legendre transform is fulfilled, for the same system, also Hamiltonian of the system is found. Using Hamiltonian and dissipation function, dissipative canonical equations are obtained. These equations are written in state space form. Then the equality to the same results obtained using the dissipative equations of generalized motion related equilibria and their stability was shown. Thus a Lyapunov function as residual energy function (REF) is justified in terms of stability of the overall system. As last step, different electrical and mechanical (physical) realization possibilities are discussed.

Published: May 2022

In this study, an interferometric fiber optic gyroscope (I-FOG) model exploiting the double-pass backward (DPB) erbium-doped superfluorescent fiber source (SFS) with both thin-film filter (TFF) and fiber bragg grating (FBG) reflectors has been constructed and the effects of temperature variations on mean wavelength and detectable minimum rotation rate (DMRR) have been theoretically analyzed. the simulations corresponding with the relations between these parameters for temperature variations in the range of −60 °C to + 90 °C, have been performed using Matlab 2021b. DMRR variations have been found as 6.01 ppm/K and 3.83 ppm/K for the system with TFF, whilst they are 15.31 ppm/K and 1.58 ppm/K for the system with FBG.
Investigation of field free region formed by dual Halbach array for focused magnetic hyperthermia
Authors: Küçükdermenci Serhat
Published: May 2022

One of the challenges with magnetic fluid hyperthermia (MFH) is the limited control of magnetic nanoparticle (MNP) oscillations. To overcome this problem new approaches such as localization of MNP oscillations are being explored. In this study, we investigated the manipulation of field free region form by dual Halbach array displacements. We used finite element method simulation to examine gradient patterns in the workspace. Then, we created an experiment platform and took point probe measurements. As a result of the research, it was found that the field free region form can be manipulated by parametric distance changes of dual Halbach array. According to the findings, the field free region can expand and its shape can change from a point-like form to an ellipse-like surface by varying the distance between the arrays. The mapping of dual Halbach array generated gradient patterns for focused MFH was investigated for the first time in this study.
Geological and palaeogeographical peculiarities of the Adamów Graben area, central Poland
Authors: Widera Marek , Dzieduszyńska Danuta , Petera-Zganiacz Joanna
Published: May 2022

From a geological and palaeogeographical point of view, the area of the Adamów Graben in the vicinity of Turek ranks amongst the best known in central Poland, with several opencast mines located here where lignite was exploited for 57 years. These large-surface exposures provide a good opportunity for detailed geological studies of strata of Late Cretaceous to Holocene age. However, the present research focuses mainly on those deposits, forms and structures that have been most thoroughly examined and are best exposed. These are Cretaceous marls and gaizes, Paleogene ‘blue clays’ and the ‘Koźmin Gravels’, Neogene sandstones, as well as the Quaternary glacial ‘Lake Koźmin’, involutions and ‘Koźmin Las’. Some of these, e.g., the ‘Koźmin Gravels’ and ‘Koźmin Las’, are not known from other Polish territories. Furthermore, results obtained by the authors over a period of nearly 30 years also include data on palaeogeographical changes across some Cenozoic intervals, especially during the early Oligocene and late Weichselian.
Bank filtration for climate resilience: potentiality of a new site along the Ismailia Canal in Egypt
Authors: Ghodeif Kamal , Wahaab Rifaat A. , Grischek Thomas , Afifi Hana , Wahsh Neveen
Published: May 2022

Bank filtration (BF) is a nature-based solution that can provide safe drinking water at a low cost, in being a green technology that benefits from natural ecosystem services and saves energy as well. The objective of the present paper is to evaluate the potentiality of a new site for bank filtration along a surface water source that experiences periods of both high and low flow. This site is located along the Ismailia Canal in the eastern Nile Delta fringe of Egypt. The present evaluation is based on exploratory drilling, installation of monitoring infrastructure and monitoring of both water level and water quality parameters for one year. The site has favourable hydrogeological conditions; the mean hydraulic conductivity of aquifer materials (sand and gravel) is 18.98 m/day. Moreover, there is a hydraulic connection between canal and aquifer; under steady conditions, the canal feeds the aquifer. Using different tracers, such as Cl, EC, Sr and SO4, the average bank filtration share is in excess of 95%. BF has reduced the particulates (turbidity) by 96%, total coliform by 99 % and total organic carbon (TOC) expressed as ultra-violet absorbance at 254 wavelengths (UVA254) by 44%. In addition, BF reduces concentrations of disinfection by-products due to its ability to remove organic matter. The potential degradation of TOC in the canal bed sediments may cause the release of iron (Fe) and manganese (Mn) to the bank filtrate water; this process is exaggerated during low-flow periods. Compared to conventional water treatment, BF is a cost-effective green technology, because no chemicals are used and no waste products are generated.
Textural characteristics, mode of transportation and depositional environment of the Stormberg Group in the Eastern Cape, South Africa: evidence from grain size and lithofacies analyses
Authors: Chima Priscilla , Baiyegunhi Christopher
Published: May 2022

The Stormberg Group comprises the Molteno, Elliot and Clarens formations and is one of four stratigraphical groups that make up the Karoo Supergroup in South Africa. The group is the highest unit in the Karoo Basin, representing the final phase of preserved sedimentation. The major problem with the Stromberg Group is that the mode of transport, hydrodynamic energy conditions and depositional environment are still poorly understood. For the present paper, grain size and lithofacies studies on selected sandstones from the Molteno, Elliot and Clarens formations were performed so as to elucidate their textural characteristics, depositional processes, sedimentation mechanisms and hydrodynamic energy conditions and to discriminate different depositional environments. The statistical parameters of grain size distribution (mean grain size, standard deviation, skewness and kurtosis) show that the sandstones are predominantly unimodal, fine grained, moderately well sorted, mesokurtic and near symmetrical. The bivariate diagrams of the aforementioned statistical parameters demonstrate that river and aeolian dune had the greatest impact on the depositional environments. Likewise, the C-M pattern (Passega diagram) shows that the sandstones were mostly deposited through tractive current process. Furthermore, the C-M diagram reveals the prevalence of rolling, suspension and graded suspension modes of sediment transportation. Seventeen sedimentary lithofacies were identified and grouped into seven lithofacies associations. These lithofacies associations indicate braided channel, overbank and swamp deposits for the Molteno Formation, alluvial fan/floodplain and playa deposits for the Elliot Formation and aeolian deposits for the Clarens Formation.
On Angular Measures in Axiomatic Euclidean Planar Geometry
Authors: Grötschel Martin , Hanche-Olsen Harald , Holden Helge , Krystek Michael P.
Published: May 2022

We address the issue of angular measure, which is a contested issue for the International System of Units (SI). We provide a mathematically rigorous and axiomatic presentation of angular measure that leads to the traditional way of measuring a plane angle subtended by a circular arc as the length of the arc divided by the radius of the arc, a scalar quantity. We distinguish between the angular magnitude, defined in terms of congruence classes of angles, and the (numerical) angular measure that can be assigned to each congruence class in such a way that, e.g., the right angle has the numerical value

π
2

{\pi \over 2}

. We argue that angles are intrinsically different from lengths, as there are angles of special significance (such as the right angle, or the straight angle), while there is no distinguished length in Euclidean geometry. This is further underlined by the observation that, while units such as the metre and kilogram have been refined over time due to advances in metrology, no such refinement of the radian is conceivable. It is a mathematically defined unit, set in stone for eternity. We conclude that angular measures are numbers, and the current definition in SI should remain unaltered.

Published: May 2022

The paper presents the comparison of uncertainty measurement estimations of the energy performances of gas stoves. The Guide to the Expression of Uncertainty in Measurement (GUM) framework and two Monte Carlo Simulation (MCM) approaches: ordinary and adaptive MCM were applied for the energy performance uncertainty: thermal energy and efficiency measurement uncertainties. The validation of the two MCMs is performed by comparing the MCM estimations to the GUM estimations for the thermal energy and efficiency measurement results. A test method designed in Indonesia National Standard SNI 7368:2011 was employed for the thermal energy and efficiency determinations. The results of the GUM and two MCM methods are in good agreement for the estimation of the thermal energy value. Significant differences of the uncertainty estimations for the thermal energy and efficiency results are observed for both GUM and MCM methods. Both the ordinary and adaptive MCM estimations give larger coverage interval compared to the GUM method. The adaptive MCM can give similar estimations with a much lower number of iterations compared to the ordinary MCM. From the estimation difference between the GUM and MCM methods, suggestions are needed for the improvement in measurement models for thermal energy and efficiency of the standard.

Published: May 2022

This paper presents an error analysis of the estimation of energy meter correction factor (CF) using a remote non-invasive technique. A method of the CF estimation based on the comparison of synchronously detected power steps in power consumption profiles of meter under test and reference meter is elaborated. The dependence of meter CF estimation uncertainty upon the magnitude of power steps, the number of power steps per observation interval, and the number of meters under test monitored by one reference meter is approximated. The synthesized consumer active power profiles are used to obtain training data points that are fit by these approximating equations.

Currently, Romania lacks a tradition of trade schools. This is due to the lack of awareness on the importance of this educational structure. Such multiple trades have been learned by simple observation from one individual to another. The importance of security measures has been taken for granted if not ignored. The number of traumas produced in wood processing has decreased rapidly due to the appearance of wood processing robots, the human factor being reduced only to their programming. The cases that arrive in the emergency departments are in a major percentage from the rural area, where the wood processing is done in the household without an adequate training and without going through a learning process. Hand injuries represent a great part of the Emergency Department presentations, and because of their fundamental functional use in daily life, repair of such lesions should be done with utmost care. Wounds of the hand typically have different degrees of severity depending on the mechanism of injury. Hand trauma probably represents the most frequent pathology of a plastic surgery ER and it should be handled with utmost care because of the fundamental function in the daily routine. The present article presents the therapeutic conduct of a complex case, multiple wounds with bone exposure, digital nerve sectioning and destruction of the flexor system of several fingers.

Published: May 2022

Complex regional pain syndrome is a clinical syndrome characterized by chronic, severe, neuropathic pain, which is associated with sensory, trophic, and autonomic disorders and decreased range of motion of the affected joint. Symptoms begin at a variable interval, at least 6 weeks after a traumatic event or after surgery. The evolution of symptoms is unpredictable, as they can range from complete and self-limiting resolution to significant chronic pain with decreasing limb function and quality of life. Depending on the absence or presence of a well-identified neural lesion, types I and II of CRPS can be observed. Because it is a relatively rare condition, it can be overlooked due to the limited experience that doctors have with this one.

A 61-year-old male patient presented with severe pain 9/10 on the Visual Analogue Scale (VAS) and a significant decrease in mobility after suffering a traumatic fracture with a left tibial plateau fracture 4 months before, which required orthopedic treatment with a plate and screws, and a left ankle sprain. Previously, the patient presented to several emergency services where he received anti-inflammatory and analgesic treatment with gradual aggravation of pain and impaired mobility of the left lower limb, walking being possible only on two axillary crutches. The patient received treatment that combined drug therapy with medical rehabilitation exercises and physical therapy agents, with a favorable evolution. At the time of discharge, the pain was 5/10 on the VAS scale and the patient could move with a single Canadian crutch.

Neoplasms are the second leading cause of death worldwide. The increase in diagnostic possibilities and development of new treatments has led to an increase in life expectancy among cancer patients.

The proximal region of the femur is a favorite site for bone metastases, these lesions being accompanied by increased mortality and morbidity.

The methods of treatment for metastatic bone disease can be surgical or non-surgical.

Bone metastases and pathological bone fractures in the proximal femur are most commonly located in the intertrochanteric or subtrochanteric region. Patients with bone metastases at this level most often require osteosynthesis with a centromedullary nail, but also plates and screws or dynamic hip screw can be used.

Bone metastases located in the femoral neck or femoral head can be treated surgically by hemiarthroplasty (HA) or total hip arthroplasty (THA). Both HA and THA have been shown to be successful surgeries in patients with bone metastases.

In patients with multiple bone metastases located in the head or neck of the femur and trochanteric region, but with increased life expectancy, resection and reconstruction using endoprostheses is a viable solution.

Given the complexity of oncological pathologies, the therapeutic decision in the case of a patient with secondary bone determinations must be established by a multidisciplinary team comprising the oncologist, orthopedic surgeon, pathologist, anesthetist, and radiotherapist.

Surgical treatment of symptomatic bone metastases that cause pain and functional impotence with limited patient mobility increases survival and quality of life regardless of the type of surgery and the implant chosen.

Coronavirus disease (COVID-19) is a pandemic-level health disaster with more than 220 million verified cases and more than 4.6 million confirmed fatalities globally as of September 2021. Since its initial detection in 2019, the virus has spread rapidly around the world. In many parts of the world, the present status of health systems has resulted in a decline in elective procedures.

Physician shortages have been clearly reported in nations that have previously been infected with the virus. Experienced and young physicians were similarly recruited to work on the front lines in medical wards and intensive care units outside of their specializations. As a result, hospitals have made significant modifications to their care systems, such as updating general wards to include ICU capabilities, postponing, and canceling elective procedures, and rethinking the duties of healthcare personnel.

Residents and fellows in training in orthopedic surgery have not been immune to these developments. As a result of many hospitals discontinuing elective procedures, orthopedic case volume has decreased significantly. Numerous educational activities must be implemented to provide workers with the knowledge and skills essential to protect themselves and their families from infection and to care for COVID-19 patients.
Involuntary Unemployment Under Ongoing Nominal Wage Rate Decline in Overlapping Generations Model
Authors: Tanaka Yasuhito
Published: May 2022

We analyze involuntary unemployment based on consumers’ utility maximization and firms’ profit maximization behavior with ongoing nominal wage rate decline. We consider a three-periods overlapping generations (OLG) model with a childhood period as well as younger and older periods under monopolistic competition with increasing, decreasing or constant returns to scale technology. When there exists involuntary unemploymnet, the nominal wage rate may decline. We examine the existenbce of involuntary unemployment in that model with ongoing mominal wage rate decline (or deflation). Even if the nominal wage rate declines, we have a steady state with involuntary unemployment and constant output and employment. We need budget deficit or budget surplus to maintain the steady state depending on whether real balance effect is positive or negative. Also we examine the possibility to achieve full-employment by fiscal policy.
Capitalization of Human Skills and Competencies – An Exploratory Model

The paper aims to synthesize the lessons learned from the analysis of the ISO 9001 quality management system standard. The objective is twofold: first, to understand the role of human capital in the conduct and success of an innovation project within a company, and secondly, to explain the simultaneous effect of this dynamic on the emergence of innovative behaviors. An exploratory study is established with the personnel of the first ISO certified company in Algeria and the proposed hypotheses are tested by the partial least squares structural equation modeling (PLS-sem) method. Analysis of the results show that by acting on certain mechanisms, these standards can be assimilated to a catalog of data that can be utilized to encourage and promote the construction and development of skills and competencies. The findings allow us to better understand the nature of the relationship that may exist between skills management and the quality approach.

Published: May 2022

Within the context that the adoption of International Financial Reporting Standards (IFRS) can be linked to institutional isomorphism, the purpose of the study was to determine how successful IFRS-adopted African countries are to convert governance and economic factors into foreign direct investment (FDI) and foreign portfolio investment (FPI). Data envelopment analysis (DEA) was used to develop two models to calculate the technical efficiency (TE) for 16 African countries that adopted IFRS (2014-2019). The first model considered how multiple economic factors as input variables are converted into FDI and FPI, while similarly, the second model considered governance factors as input variables.

The extant ethnomedicines of the Eastern Ghats of south India were inventoried. The ethnobotanical survey conducted during the months of June to August 2018 in the six different hills of Eastern Ghats divulged a total of 54 (76%) medicinal plants belonging to 34 families being currently used by the herbal practitioners. The comprehensive details on the vernacular name, binomial, family, and plant part(s) used, and type of drug preparation of the ethnomedicines used for the various disease(s) are tabulated. The plant family Fabaceae (with five ethnomedicines) followed by Euphorbiaceae and Solanaceae (four each) were the dominant contributor in the Eastern Ghats. Interestingly, the same families were found contributing in similar pattern (nine and four each) in the literature pertaining to the Eastern Ghats, indicating their heritage and significance. Further, the ethnobotanical survey revealed that the leaves (25%) and paste form (46%) are the predominant plant part and drug type used respectively in the hills. The analysis also revealed the prevalent use of single drug (70%) and their overall depletion (24%) underlining the urgency to conserve them.
Inflorescence appearance timing and production rate traits in wild Zoysiagrass (Zoysia spp)

Zoysiagrass (Zoysia spp.) has excellent turf quality and can be applied to various uses for personal space to public sports areas or commercial landscapes. However, it has disadvantages such as slow growth rate, cold hardiness, low seed yield, and hard to establish from seeds, which cannot be improved with agricultural practices. Therefore, breeding a new cultivar as a hybrid could be an efficient strategy to improve the Zoysiagrass cultivar. In fact, hybrid zoysiagrass shows mixed traits of both parents in morphology and heterosis in growth. However, inflorescence appearance and its rate are known to make a hybrid. Thus, the variety of inflorescence appearance timing and production rate were investigated among 549 genetic resources. As a result, only 5.38% of the variety among survived zoysiagrass after transplanting showed more than 30% inflorescence appearance within the given period. During that, some varieties showed a reduction of total inflorescence. Hence, we report the diversity of inflorescence appearance timing and production rate that could be useful for breeders and researchers breeding new Zoysiagrass cultivars.
