The Fruitless Branch and the Eternal Security of the Believer
Authors: Badu Anthony Yaw , Kuwornu-Adjaottor Jonathan E.T.
Published: February 2022

The quest for the identification of the fruitless branch has been an enduring theological battleground between the Calvinists and the Arminians who argue as to whether or not the removal of the fruitless branch indicates the loss of eternal salvation. Using a qualitative approach, this study sought to examine the various interpretations on the eternal security of the believer with a focus on three phrases in the passage namely; ἐν ἐμοὶ, (in me) and airō (cut off) and μείνατε ἐν ἐμοί (abide in me). Findings show that the analogy of the vine is a critique to the belief of once saved, forever saved because of the use of “in me” and the “cutting off” of the fruitless branch which cannot happen without a prior linkage to the stem of the vine. Since the fruitless branch can only represent one of the various views, it is recommended that fruitfulness should be the key to one’s walk with the Lord to
avoid eternal separation.

Authors: Nkuna Vusimuzi Goodman
Published: February 2022

This paper presents a critical review of the book titled An African Background to the Old Testament written by Rev. Dr. Isaac Boaheng. The purpose of this review is to assess how this book has achieved its objective of enhancing African readers’ contextual reading of the Old Testament(OT). From my perspective as a graduate student in Practical Theology, I am of the opinion that the book has achieved this purpose. Therefore, this review serves to sustain this assertion. The review starts by presenting the book’s overview commencing
from the Foreword and ending with Chapter 7. I then conclude the review with a brief evaluation of the extent to which the book has achieved its stated and implied goal(s) followed by some recommendations.
THE RESULTS OF RESEARCH PNEUMATIC ELECTROMAGNETIC PULSATOR COMBINED WITH COLLECTOR
Authors: Yatsunskyi Petro
Published: February 2022

This article demonstrates the results of experimental research one of the pulsators. Its main difference from others is a pneumatic electromagnetic pulsator in combination with a collector. Therefore, this article describes in detail the process of studying the pulsator. The planned experiment was carried out on by Factorial experiments with multiple factors. The influence of factors (the ripple frequency n, the milk ejection q and the ratio between strokes t/T) on the vacuum pressure in the inter wall chamber of teat cups was studied. The regression equation of the dependence response criterion on factors is modeled. This dependence is demonstrated graphically. Also there is a contour graph which is for more detailed information.
Challenging the Disk Instability Model. I. The Case of YZ LMi
Authors: Baptista Raymundo , Schlindwein Wagner
Published: February 2022

Observations of YZ LMi show enhanced emission along the stream trajectory beyond impact at the disk rim during outbursts as well as when the quiescent disk is large. We investigated whether these features can be explained in terms of either gas stream overflow or penetration within the frameworks of the disk instability model (DIM) and the mass-transfer instability model (MTIM) of outbursting disks. Gas stream overflow is not possible because the vertical scale height of the stream is significantly lower than that of the outer disk and because there is no combination of parameters which enables stream overflow on a larger disk while preventing it on a smaller disk. Stream penetration requires the gas stream to be denser than the outer disk regions. This requirement cannot be met by a low-viscosity DIM disk because its density is significantly larger than that of the gas stream over the whole range of mass-transfer rates where the thermal-viscous instability occurs. On the other hand, the high-viscosity MTIM disk has much lower densities which decrease with increasing radius, easily allowing for gas stream penetration during outbursts (when mass-transfer rate and stream density increase) as well as in large quiescent disks. The observed features are not consistent with DIM, but can be plausibly explained by MTIM. These results suggest that the outbursts of YZ LMi are the response of a high-viscosity disk to bursts of enhanced mass-transfer rate. In this case, the outburst decline timescale of (2–3) days implies a viscosity parameter in the range α = 3–4.
An Atomic Spectral Survey of WASP-76b: Resolving Chemical Gradients and Asymmetries

Published: February 2022

Ultrahot Jupiters are gas giants that orbit so close to their host star that they are tidally locked, causing a permanent hot dayside and a cooler nightside. Signatures of their nonuniform atmospheres can be observed with high-resolution transit transmission spectroscopy by resolving time-dependent velocity shifts as the planet rotates and varying areas of the evening and morning terminator are probed. These asymmetric shifts were seen for the first time in iron absorption in WASP-76b. Here, we search for other atoms/ions in the planets transmission spectrum and study the asymmetries in their signals. We detect Li i, Na i, Mg i, Ca ii, V i, Cr i, Mn i, Fe i, Ni i, and Sr ii, and tentatively detect H i, K i, and Co i, of which V, Cr, Ni, Sr ii, and Co have not been reported before. We notably do not detect Ti or Al, even though these species should be readily observable, and hypothesize this could be due to condensation or cold trapping. We find that the observed signal asymmetries in the detected species can be explained in different ways. We find a relation between the expected condensation or ionization temperatures and the strength of the observed asymmetry, which could indicate rain-out or recombination on the nightside. However, we also find a dependence on the signal broadening, which could imply a two-zoned atmospheric model, in which the lower atmosphere is dominated by a day-to-night wind, while the upper atmosphere is dominated by a vertical wind or outflow. These observations provide a new level of modeling constraint and will aid our understanding of atmospheric dynamics in highly irradiated planets.
Warping Away Gravitational Instabilities in Protoplanetary Discs
Authors: Rowther Sahl , Nealon Rebecca , Meru Farzana
Published: February 2022

We perform three-dimensional smoothed-particle hydrodynamics simulations of warped, non-coplanar gravitationally unstable discs to show that as the warp propagates through the self-gravitating disk, it heats up the disk rendering it gravitationally stable, thus losing their spiral structure and appearing completely axisymmetric. In their youth, protoplanetary discs are expected to be massive and self-gravitating, which results in nonaxisymmetric spiral structures. However recent observations of young protoplanetary discs with the Atacama Large Millimeter/submillimeter Array have revealed that discs with large-scale spiral structure are rarely observed in the midplane. Instead, axisymmetric discs, with some also having ring and gap structures, are more commonly observed. Our work invloving warps, non-coplanar disk structures that are expected to commonly occur in young discs, potentially resolves this discrepancy between observations and theoretical predictions. We demonstrate that they are able to suppress the large-scale spiral structure of self-gravitating protoplanetary discs.

Published: February 2022

In the coming decade, a new generation of massively multiplexed spectroscopic surveys, such as the Prime Focus Spectrograph Galaxy Evolution Survey (PFS), Wide Area Vista Extragalactic Survey-Deep (WAVES), and Multi-Object Optical and Near-infrared Spectrograph (MOONS) for the Very Large Telescope, will probe galaxies in the distant universe in vastly greater numbers than was previously possible. In this work, we generate mock catalogs for each of these three planned surveys to help quantify and optimize their scientific output. To assign photometry into the UniverseMachine empirical model, we develop the Calibrating Light: Illuminating Mocks By Empirical Relations procedure using Ultra Deep Survey with the Visible and Infrared Survey Telescope for Astronomy (UltraVISTA) photometry. Using the published empirical selection functions for each aforementioned survey, we quantify the mass completeness of each survey. We compare different targeting strategies by varying the area and targeting completeness, and quantify how these survey parameters affect the uncertainty of the two-point correlation function. We demonstrate that the PFS and MOONS measurements will be primarily dominated by cosmic variance, not shot noise, motivating the need for increasingly large survey areas. On the other hand, the WAVES survey, which covers a much larger area, will strike a good balance between cosmic variance and shot noise. For a fixed number of targets, a 5% increased survey area (and ∼5% decreased completeness) would decrease the uncertainty of the correlation function at intermediate scales by 0.15%, 1.2%, and 1.1% for our WAVES, PFS, and MOONS samples, respectively. Meanwhile, for a fixed survey area, 5% increased targeting completeness improves the same constraints by 0.7%, 0.25%, and 0.1%. All of the utilities used to construct our mock catalogs and many of the catalogs themselves are publicly available.
Simulations of Stochastic Long-term Variability in Leptonic Models for External-Compton and Synchrotron Self-Compton Dominated Blazars
Authors: Thiersen Hannes , Zacharias Michael , Böttcher Markus
Published: February 2022

In this work we investigate the nature of multiwavelength variability of blazars from a purely numerical approach. We use a time-dependent one-zone leptonic blazar emission model to simulate multiwavelength variability by introducing stochastic parameter variations in the emission region. These stochastic parameter variations are generated by Monte Carlo methods and have a characteristic power-law index of α = −2 in their power spectral densities. We include representative blazar test cases for a flat spectrum radio quasar and a high-synchrotron peaked BL Lacertae object for which the high-energy component of the spectral energy distribution is dominated by external-Compton and synchrotron self-Compton emission, respectively. The simulated variability is analyzed in order to characterize the distinctions between the two blazar cases and the physical parameters driving the variability. We show that the variability’s power spectrum is closely related to underlying stochastic parameter variations for both cases. Distinct differences between the different progenitor variations are present in the multiwavelength cross-correlation functions.
A Matched Survey for the Enigmatic Low Radio Frequency Transient ILT J225347+862146
Authors: Huang 黃 Yuping 宇平 , Anderson Marin M. , Hallinan Gregg , W. Lazio T. Joseph , Price Danny C. , Sharma Yashvi
Published: February 2022

Discovered in 2011 with LOFAR, the 15 Jy low-frequency radio transient ILT J225347+862146 heralds a potentially prolific population of radio transients at <100 MHz. However, subsequent transient searches in similar parameter space yielded no detections. We test the hypothesis that these surveys at comparable sensitivity have missed the population due to mismatched survey parameters. In particular, the LOFAR survey used only 195 kHz of bandwidth at 60 MHz, while other surveys were at higher frequencies or had wider bandwidth. Using 137 hr of all-sky images from the Owens Valley Radio Observatory Long Wavelength Array, we conduct a narrowband transient search at ∼10 Jy sensitivity with timescales from 10 minutes to 1 day and a bandwidth of 722 kHz at 60 MHz. To model the remaining survey selection effects, we introduce a flexible Bayesian approach for inferring transient rates. We do not detect any transient and find compelling evidence that our nondetection is inconsistent with the detection of ILT J225347+862146. Under the assumption that the transient is astrophysical, we propose two hypotheses that may explain our nondetection. First, the transient population associated with ILT J225347+862146 may have a low all-sky density and display strong temporal clustering. Second, ILT J225347+862146 may be an extreme instance of the fluence distribution, of which we revise the surface density estimate at 15 Jy to 1.1 × 10−7 deg−2 with a 95% credible interval of (3.5 × 10−12, 3.4 × 10−7) deg−2. Finally, we find a previously identified object coincident with ILT J225347+862146 to be an M dwarf at 420 pc.
Spectral Properties of the Soft X-Ray Transient MAXI J0637−430 Using AstroSat
Authors: Thomas Neal Titus , Gudennavar Shivappa B. , Misra Ranjeev , Bubbly S. G.
Published: February 2022

Soft X-ray transients are systems that are detected when they go into an outburst, wherein their X-ray luminosity increases by several orders of magnitude. These outbursts are markers of the poorly understood change in the spectral state of these systems from the low/hard state to the high/soft state. We report the spectral properties of one such soft X-ray transient: MAXI J0637−430, with data from the SXT and LAXPC instruments on board the AstroSat mission. The source was observed for a total of ∼60 ks in two observations on 2019 November 8 and 21 soon after its discovery. Flux-resolved spectral analysis of the source indicates the presence of a multicolor blackbody component arising from the accretion disk and a thermal Comptonization component. The stable low temperature (∼0.55 keV) of the blackbody component points to a cool accretion disk with an inner disk radius of the order of a few hundred kilometers. In addition, we report the presence of a relativistically broadened Gaussian line at 6.4 keV. The disk-dominated flux and photon power-law index of ⪆2 and a constant inner disk radius indicate the source to be in the soft state. From the study we conclude that MAXI J0637−430 is a strong candidate for a black hole X-ray binary.
A New Iron Emission Template for Active Galactic Nuclei. I. Optical Template for the Hβ Region*
Authors: Park 박 Daeseong 대성 , Barth Aaron J. , Ho Luis C. , Laor Ari
Published: February 2022

We present a new empirical template for iron emission in active galactic nuclei (AGNs) covering the 4000–5600 Å range. The new template is based on a spectrum of the narrow-line Seyfert 1 galaxy Mrk 493 obtained with the Hubble Space Telescope. In comparison with the canonical iron template object I Zw 1, Mrk 493 has narrower broad-line widths, lower reddening, and a less extreme Eddington ratio, making it a superior choice for template construction. We carried out a multicomponent spectral decomposition to produce a template incorporating all the permitted and forbidden lines of Fe ii identified in the Mrk 493 spectrum over this wavelength range, as well as lines from Ti ii, Ni ii, and Cr ii. We tested the template by fitting it to AGN spectra spanning a broad range of iron emission properties, and we present a detailed comparison with fits using other widely used monolithic and multicomponent iron emission templates. The new template generally provides the best fit (lowest χ
2) compared to other widely used monolithic empirical templates. In addition, the new template yields more accurate spectral measurements including a significantly better match of the derived Balmer line profiles (Hβ, Hγ, Hδ), in contrast with results obtained using the other templates. Our comparison tests show that the choice of iron template can introduce a systematic bias in measurements of the Hβ line width, which consequently impacts single-epoch black hole mass estimates by ∼0.1 dex on average and possibly up to ∼0.3–0.5 dex individually.
The Mid-UV Spectrum of Irradiated NaCl at Europa-like Conditions
Authors: Brown Michael E. , Denman William T. P. , Trumbo Samantha K.
Published: February 2022

Recent observations from the Hubble Space Telescope show a mid-UV absorption feature localized to leading-hemisphere chaos regions on Europa. The same regions were previously found to have a visible absorption at 450 nm that was attributed to the presence of irradiated NaCl. The lack of any additional diagnostic absorptions for NaCl in the visible spectrum of these terrains made confirmation of this identification difficult. Here we use laboratory experiments to show that NaCl irradiated at Europa’s surface temperatures develops an absorption at ∼220 nm, consistent with the new detection in Europa’s mid-UV spectrum, strongly supporting the NaCl identification. Irradiated NaCl in leading-hemisphere chaos terrain would suggest that sodium and chlorine are important components of Europa’s subsurface ocean.
Understanding and Addressing Moral Distress
Authors: Epstein Elizabeth , Delgado Sarah
Published: February 2022

Moral distress occurs when one knows the ethically correct action to take but feels powerless to take that action. Research on moral distress among nurses has identified that the sources of moral distress are many and varied and that the experience of moral distress leads some nurses to leave their jobs, or the profession altogether. This article considers both moral distress and moral residue, a consequence of unresolved moral distress. First, we will explain the phenomenon of moral distress by providing an historical overview, identifying common sources, and describing strategies for recognizing moral distress. Next we will address moral residue and the crescendo effect associated with moral residue. We will conclude by considering ways to address moral distress and the benefits of a moral distress consult service.
Moral Courage and the Nurse Leader
Authors: Edmonson Cole
Published: February 2022

Today’s nurse leaders practice in very complex environments. This complexity leads to value conflicts and creates the potential for moral distress. Jameton’s sentinel work framed the concept of moral distress as arising when one knows the morally right thing to do, but cannot do so because of organizational constraints. In this article the author reviews sources of moral distress among nurse leaders, discusses the nurse leader’s responsibility for demonstrating and supporting moral courage, identifies threats to moral courage among nurse leaders, offers strategies to promote moral courage, and makes recommendations for the continuing development of moral courage.
For a Fistful of Barley: More on the Remuneration of Scribes and State Taxation in the Neo-Babylonian Eanna Temple
Authors: Jursa Michael , Levavi Yuval
Published: February 2022

Cet article retrace l’évolution de l’institution de l’ upnu dans le temple d’Eanna du IX e au VI e  siècle avant notre ère. À l’origine, il s’agissait d’une taxe prélevée par le scribe du temple sur les transactions et les dépenses internes du temple. Le paiement de l’ upnu a été converti en un impôt payable à la couronne au plus tard sous Nabonide, mais peut-être déjà un peu plus tôt, sous Nabuchodonosor. Cette évolution est un autre aspect du long processus par lequel Eanna a été placé sous un contrôle royal de plus en plus étroit au VI e  siècle.
La variation traitée et modélisée pour une langue standardisée : le métadiscours registral dans les manuels de FLE
Authors: Axampanopoulos Panagiotis
Published: February 2022

Dans cet article, il est question du traitement de la variation dans les matériaux didactiques et, en particulier, dans les manuels de français langue étrangère (FLE) édités en France, qui circulent largement sur l’échelle internationale et offrent un support essentiel pour l’enseignement et la diffusion du français en dehors de l’Hexagone. En partant du fait, couramment observé dans les manuels, que la variation y est majoritairement traitée en termes de registres de langue, on s’intéresse aux aspects et aux effets de ce métadiscours à propos de la langue et de sa variation, créateur de ces découpages sociolinguistiques. En raison de son mode de structuration spécifique, la langue étant à la fois son objet et le moyen essentiel de son actualisation, ce métadiscours est analysé ici dans ses variantes et sa visée à l’aide de la notion de réflexivité, telle qu’elle est élaborée récemment dans le domaine de l’anthropologie linguistique. L’étude des opérations réflexives – linguistiques et, plus largement, sémiotiques – en jeu dans le processus socialement différenciateur des usages du français dans six manuels, retenus pour exemplifier les grandes tendances de ce métadiscours, nous permettra : d’une part, de mettre en évidence le mode de construction privilégié du savoir sociolinguistique en contexte didactique et, d’autre part, d’en souligner les effets, liés à la reproduction d’un français standardisé en vue de son enseignement et sa diffusion internationale.
Les fragilités urbaines dans les métropoles. Discours et représentations habitantes à partir du Baromètre des Quartiers
Authors: Duarte Paulette
Published: February 2022

Les processus de métropolisation en cours et à venir invitent à (re)questionner les espaces urbains dans leur fonctionnement et leur dynamisme. Les espaces métropolitains, souvent présentés comme des espaces dynamiques, valorisés, sont-ils des espaces homogènes et cohérents ? Les métropoles ne sont-elles pas plutôt des espaces contrastés, dans lesquels des « fragilités » urbaines sont également possibles ? Pour définir ces fragilités urbaines, l’auteure se saisit du matériau discursif développé par le Baromètre des Quartiers à Grenoble, et analyse les représentations sociales d’habitants à l’égard d’espaces de vie urbains. Les représentations habitantes, via l’analyse des discours, nous apprennent que les espaces urbains sont considérés comme « fragiles » parce qu’ils pourraient s’altérer, que leur « fragilité » a pour caractéristique d’être multidimensionnelle, pluri-scalaire et relative, et que la (dé)-fragilisation des espaces métropolitains est un processus instable.

La patrimonialisation des langues (minorées) : une voie (obligatoire) vers le marché ?
Authors: Colonna Romain
Published: February 2022

La langue est apparue dans le contexte de la mondialisation comme un élément central, porteur d’une identité territoriale à préserver et/ou à promouvoir, susceptible de devenir ainsi l’élément de l’expression revendicative identitaire et un puissant marqueur territorial. Parallèlement, les langues minorées semblent avoir trouvé un débouché à travers un processus complexe et protéiforme de patrimonialisation . Celui-ci opère une redistribution axiologique dont le processus de marchandisation d’usages linguistiques peut profiter afin d’optimiser la visée commerciale. Nous tentons tout d’abord dans cet article de mieux comprendre l’association désormais permanente, au moins dans le discours politique, entre « langues minorées » et « patrimoine ». Le champ sémantique et celui des représentations peuvent être bornés à la fois par une forme de folklorisation et/ou muséification des objets visés par la patrimonialisation et par une valorisation et visibilité assurées pour le territoire. Dans ce contexte, la langue, tel un label, une « langue-drapeau » pour reprendre l’expression de Jean Laponce, est susceptible d’apparaître davantage comme gage d’identité et de valeurs liées à l’authenticité, à l’historicité et à l’émotion plutôt que comme un instrument de communication. Partant de ce principe et dans le contexte patrimonial, nous chercherons à mieux comprendre la mobilisation d’usages en langue corse à travers l’observation de plates-formes de vente en ligne de produits agroalimentaire, cosmétiques ou de spiritueux. Dans le cadre d’une part d’un processus de patrimonialisation et d’autre part d’opérations de marchandisation, nous poserons donc la question de la (re)fonctionnalisation des usages linguistiques en contexte minoré.
Ce que la théorie des champs nous dit de l’administration européenne (I). Un retour réflexif sur le champ de l’eurocratie

Published: February 2022

Cet article a pour but de clarifier ce que le concept de champ, et plus particulièrement de « champ bureaucratique », apporte à la compréhension des institutions et des politiques européennes, et de l’exemplifier à partir d’un ensemble de tendances qui traversent l’administration européenne. Que signifie exactement ce concept ? En quoi diffère-t-il ou se rapproche-t-il d’autres théories ? Et surtout, qu’apporte-t-il à la compréhension de l’Union européenne (UE), tant du point de vue de ses processus concrets, que de la structure sociale qui donne forme et sens au réseau indissociablement humain et organisationnel que représente l’administration européenne ? Pour le comprendre, l’article revient sur le concept de champ de l’eurocratie et montre en quoi ce dernier constitue une grille de lecture pour traiter des transformations de l’administration sur le moyen terme des 25 dernières années puis depuis la conjoncture ouverte avec les élections européennes de 2015.

Published: February 2022

Osteoarthritis of the thumb carpometacarpal (CMC) joint is the most common type of arthritis of the hand. The goal of the study was to evaluate clinical results and radiographic changes after arthroscopic partial trapeziectomy combined with ligament shrinkage and K-wire fixation to treat thumb CMC joint arthritis. From February 2013 to March 2014, 24 patients with thumb CMC joint arthritis received this arthroscopic procedure. We investigated the preoperative and postoperative Modified Mayo Wrist Score (MMWS); Disabilities of the Arm, Shoulder and Hand (DASH) score; radiographic changes; and associated complications. Sixteen patients completed 5 years of functional score and radiographic follow-up. Comparison of preoperative and postoperative MMWS and DASH scores showed significant improvement after the arthroscopic procedure. Pre-operative and postoperative evaluation of radiographic changes showed significant differences in the CMC joint distance, scaphoid-metacarpal distance, trapezium-metacarpal distance, and metacarpal prominence distance. This arthroscopic procedure is an effective and less invasive method for the treatment of CMC joint arthritis. This procedure can improve clinical function, preserve the mechanical height of the trapezium, and increase CMC joint space. We report our surgical technique and some pitfalls that required attention during the arthroscopic procedure. [

Mother Tongue Teacher Education in Sweden
Authors: Ringblom Natalia , Mattsson Olga
Published: February 2022

This chapter looks at the development of a course for mother tongue teachers in Sweden and discusses the methodology of teaching a course that allows participants acquire a deeper knowledge about the challenges of mother tongue instruction and engages them in collaborative learning. The course focused on developing knowledge, skills, and attitudes to prepare the participants for working professionally as mother-tongue teachers of Russian and to be involved in the development of the subject. The main purpose was to bring together relevant knowledge from research, provide necessary cultural competence, and create an atmosphere for open reflection. The ambition was that the course participants would understand that the way they teach and the choices they make should be aligned with previous research. The results suggest that the participants had very different perspectives on their role as a teacher as a result of their cultural background. This role became much clearer with the help of reflection with colleagues.
DEMATEL Analysis of Medication Non-Adherence Behavior of Patients
Authors: Saha Saibal Kumar , Adhikary Anindita , Jha Ajeya , Mehta Vijay K.
Published: February 2022

Physicians are directly responsible for the treatment of patients. They affect patient behaviour and beliefs. Their point of view with respect to medication adherence behaviour of patients is crucial for getting insights into the cause-and-effect relationship of factors of medication non-adherence. This paper tries to find the cause-and-effect relationship of seven factors based on the physician perspective. With the help of paired comparison method, the expert beliefs of 30 physicians were captured using a structured questionnaire. DEMATEL analysis was done to find the cause-and-effect relationship between different factors. 'Belief that medication adherence is not important' emerged as the most important factor for medication non-adherence. If patients' beliefs can be modified through intervention, their behaviour may be altered, improving medication adherence rates.
Uncertainty From Sampling
Authors: Tsimillis Kyriacos C. , Michael Sappho
Published: February 2022

ISO/IEC 17025:2017 and ISO 15189:2012 specify the requirements for the competence of laboratories. The former refers to laboratories in general, whose activities include testing, calibration and sampling followed by testing or calibration while the latter refers to medical laboratories. Despite the differences between the two standards reflecting the specific needs each of them is addressing, the development of these two documents has, until now, followed similar paths. In this presentation the requirements of ISO/IEC 17025 referring to sampling and the uncertainty arising from it are presented underlining what testing laboratories need to consider. In addition, a comparison with the requirements of ISO 15189 with regard to sampling and measurement uncertainty is made. Based on this, the question whether an approach on uncertainty from sampling similar to the one introduced by the new ISO/IEC 17025 can be included in the revision of ISO 15189, currently under way, is addressed.

The paper presents the design approach of a low power stretchable wearable epidermal electronic device as part of an advanced athlete performance management framework to perform multi-parametric, multi-modal measurements of vital physiological parameters through the skin and via sweat analysis. It can be used to seamlessly monitor athletes, to prevent serious health complications and injuries during training, sudden death and complications related to overtraining. The proposed framework allows real-time physiological monitoring, tracking, prediction and quantification of athletic performance and estimation of recovery time after an injury, an illness or the overtraining syndrome. It is based on low-cost and clean room-based fabrication techniques and interconnects and readout electronics based on commercially available off-the-shelf components and application-specific integrated circuits. A data analytics platform incorporates real-time monitoring to identify the susceptibility to sudden death, health complications or injury, for the athlete, executing a personalized prediction model

Research of Ferronickel Manufacturing Process by Selective Reduction of Poor Iron-Chromium-Nickel Ores
Authors: Bigeev Vachit A. , Potapova Marina V. , Makarova Irina V.
Published: February 2022

In metallurgy production nickel is an important alloying element used in the production of stainless, heat-resistant, acid-resistant grades of steel. For the development of ferronickel production in the Russian Federation, it is proposed to involve in processing complex poor iron-chromium-nickel ores of the Khalilovskoye deposit, which are not used at the present time. In the frame of this work the dependences of the elements reduction degrees of iron-chromium-nickel ore on the iron extraction degree were studied. These dependencies are necessary for the choice of the composition and development of ferronickel production technology. Burned ore raw materials were subjected to a selective carbothermal reduction in the laboratory electric arc furnace. In the obtained ferroalloy the nickel content decreased from 65 to 3%, phosphorus - from 0.68 to 0.38%, sulfur - from 0.19 to 0.10% with an increase in the reducing agent consumption. With the reduction of 1% iron, the recovery of nickel was only 50%, with 5% - 65–75%, with 20% - 95%. The content of iron oxides in the partially reduced melt with an increase in coke consumption decreased from 61 to 53%, and nickel oxide - from 0.192 to 0.010%. The analysis of the dependences allows us to make a conclusion that it is inappropriate to recover less than 5% of iron due to the low degree of nickel recovery (less than 70%). The rational degree of iron reduction from ore raw materials is 5-10%, which corresponds to the nickel content in the ferroalloy 10-20%, phosphorus - 0.3-0.5%, sulfur - 0.08-0.09%. Obviously, the resulting crude ferronickel needs refining, first of all dephosphorization.

Improving the quality and reliability of machines is a necessary condition for the development of mechanical engineering. Most often, the main reason for the failure of machines is the wear of working parts. The reliability of the machines is ensured primarily by achieving high-quality materials of the working parts with the required level of mechanical properties.The short service life of parts reduces the economic efficiency of many machines and industrial equipment and results in irretrievable metal losses.Under conditions of wear that are not associated with large impact loads, white wear-resistant cast irons, which wear resistance is 5-10 times greater than structural steels, have shown themselves well.Grinding and the main processes of non-ferrous and ferrous metal ore-dressing, as well as coal, mining and chemical raw materials are associated with the need to process large volumes of ore slurry (pulps). For the implementation of complex dressing technological schemes at modern factories and the removal of refuse materials, centrifugal sand and soil pumps are widely used, the service life of which is limited. Impellers, bends, and sealing elements are the first to break down, resulting in significant repair costs and reduced productivity due to forced downtime [1-3].To replace worn out parts, it is necessary to remove the pumps from the operation, or install redundant pumps for the main technological stages, which takes up to 20-25 % of the productive time. If we take into account the fact that due to the wear of these parts, the pumps have lower productivity, then the total losses on a national scale are enormous.The low durability of the cast working parts of the pumps is related to the fact that the properties of used alloys do not always correspond to the operating conditions. But even parts made of the same cast iron composition and working under the same conditions have a different service life. This is due to the fact that changes in the concentrations of alloying elements within the grade composition strongly affect their properties [4-6].

Authors: Lezhnev Sergey N. , Naizabekov Abdrakhman B. , Panin Evgeniy
Published: February 2022

Recycling of waste, both ferrous and non-ferrous metals is a useful process for the economy of any country. In this paper, a new technology for recycling bar scrap of ferrous metals by rolling on radial-shear rolling mills was proposed to obtain a marketable product in the form of bars with an ultrafine-grained gradient structure. Studies have shown that the deformation of the rod of scrap pieces of rebar from steel 18G2S mill of radial-shear rolling can significantly dispersed structure with obtaining the gradient ultrafine-grained structure, and this in turn leads to an increase of the mechanical characteristics of this steel grade. Thus, the tensile strength of steel grade 18G2S deformed at the radial-shear rolling mill was 620 MPa (at the initial value of 365 MPa).

Published: February 2022

The paper reveals the hybrid structure strength studies results, which consists of composite and metal parts. The object of the study was an experimental transmission shaft of an aircraft high-lift system. It consisted of a composite tube and metal flanges. New high-strength composites, modern metal powders and additive technology were used for its manufacture. This is the feature that differ the shaft from the typical metal structures used at present. The shaft strength investigation included static tests and calculations. During the tests, the maximum torque and the corresponding shaft twist angle were determined. Based on the computational analysis results, the critical stresses and reserve factors of its structural elements were calculated. The assessment of the effectiveness of the new technologies application for joining structural elements using discrete pins was carried out.
The Impact of Ferro-and Superparamagnetic Nickel Particles on the Magnetism of YBCO Superconducting Ceramics
Authors: Volosatova V.S. , Kuz'mina A.S. , Kuz'min Mikhail P.
Published: February 2022

The article examines the effect of nickel nanoparticles on the magnetic properties of the YBCO superconductor. The ceramics were obtained by solid-phase synthesis using yttrium oxide, copper (II) oxide, and barium carbonate with the addition of carbon nanotubes "Taunite" of different concentrations (0, 20, 50, 70, 100 mg). Magnetic studies have demonstrated that ferromagnetism and superparamagnetism are both observed in the samples, which can be explained by the presence of nickel particles. The dependences of the magnetization in the applied magnetic field of the sample without the addition of the carbon nanotubes "Taunite" have a paramagnetic course, and their slope monotonically increased with decreasing temperature. The coercive force of the samples and the value of the magnetic moment has been determined to increase upon the decrease in temperature. The high homogeneity of the heterostructures has been demonstrated in the graphs of FC/ZFC explained by the uneven distribution of nickel nanoparticles, which do not integrate into the crystal lattice and, due to the long-range order of interaction, do not make a strong contribution to the magnetization.

Published: February 2022

The use of social media has increased in the recent era compared to the past. Social media is the collection of tools and, online spaces available for communication among individuals and groups. Easy access and accessible communication facilities, flexible languages, and ability to create free accounts are the main reasons for the popularityof Facebook (FB) among nationsworldwide, including Sri Lankans. The library of the Buddhist and Pali University (BPU) of Sri Lanka wants to introduce online user groups to communicate and sharelibrary-related information through FB.Currently, Wi-Fi facilities are used to communicate with academic staff and higher-level administrative staff. Hence the problem affected was that the behaviour of the non-academic middle-level staff in an online environment is not understood. The primary objective of the study is to understand the behavior of the university non-academic middle-level staff in an online environment before introducing an online communication system for them. In addition, it is necessary to be aware of 'why and how' FB is used by the staff. The survey method was used to collect data using a questionnaire from the selected sample using a mixed method. An applied research type wasadhered to conduct the study. Findings revealed that the primary purpose of the use of FB by BPUmiddle-level staff was to look forward 'for news'. The behavioral study proved that there are efficient users of FB and they are capable of sharing, delivering, liking, commenting, criticizing, and uploading the posts.However, they are not proficient in creating many exciting posts.The main problem that seems to affect them is 'unknown friend requests.' It was found that there is a significant association between gender and purpose, and gender and postingauthentic personnel information. It was recommended to create online 'library user groups' for communication purposes and to hold IT training sessions for middle-level staff to improve their knowledge and skills in IT usage for library related activities.

Interstitial macrophages (IMs) are key regulators of allergic inflammation. We previously showed that the absence of semaphorin 3E (Sema3E) exacerbates asthma features in both acute and chronic asthma models. However, it has not been studied whether Sema3E, via its receptor plexinD1, regulates IM function in allergic asthma. Therefore, we investigated the role of plexinD1 deficiency on IMs in allergic asthma. We found that the absence of plexinD1 in IMs increased airway hyperresponsiveness, airway leukocyte numbers, allergen-specific IgE, goblet cell hyperplasia, and Th2/Th17 cytokine response in the house dust mite (HDM)–induced allergic asthma model. Muc5ac, Muc5b, and α-SMA genes were increased in mice with Plxnd1-deficient IMs compared with wild-type mice. Furthermore, plexinD1-deficient bone marrow–derived macrophages displayed reduced IL-10 mRNA expression, at both the baseline and following HDM challenge, compared with their wild-type counterpart mice. Our data suggest that Sema3E/plexinD1 signaling in IMs is a critical pathway that modulates airway inflammation, airway resistance, and tissue remodeling in the HDM murine model of allergic asthma. Reduced IL-10 expression by plexinD1-deficient macrophages may account for these enhanced allergic asthma features.
