‘Un método’ para proceder: Ángel González y la poesía de Ángeles Mora
Authors: Keefe Ugalde Sharon
Published: March 2021

Este estudio analiza el efecto catalítico de la poesía de Ángel González (Oviedo, 1925-2008) en la obra poética de Ángeles Mora (Rute, Córdoba, 1952). Una declaración de la poeta, una preferencia por determinados procedimientos discursivos, y un poema-homenaje confirman el impacto de González en el arte poético de Mora. El estudio deja en claro que, si el poeta de la Generación de 50 estimuló la creatividad temprana de Mora, ella supo transformar esa inspiración en la construcción de una voz propia, una voz centrada en la subjetividad femenina.
Notas de rodaje. Diálogos visuales entre las poéticas de Olvido García Valdés y Pier Paolo Pasolini
Authors: Calabrese Giuliana
Published: March 2021

Las poéticas de Olvido García Valdés y de Pier Paolo Pasolini comparten rasgos comunes que derivan sobre todo de la elaboración de elementos visuales de la realidad: a partir de la inmersión del sujeto en entornos rurales o artísticos, los poemarios La religión de mi tiempo del italiano y Del ojo al hueso, que la poeta asturiana compone justo después de haber traducido al español el libro de Pasolini, presentan una poética visual común que permite adentrarse en un camino metafísico cuya única meta trascendente es la dimensión de soledad animal e histórica.

Abstrak

Toleransi dalam praktik beragama di Indonesia merupakan komponen penting dalam mewujudkan masyarakat yang damai. Namun era modern ini masih banyak kasus praktik keagamaan yang menyalahgunakan makna toleransi demi kepentingan organisasinya. Kegiatan dakwah yang selalu menerapkan prinsip toleran sanggup menarik minat mad’u terhadap Islam, sementara kegiatan intoleran yang dilakukan ormas semakian mengucilkan aktivitas dakwah dari perhatian masyarakat. Sudah tentu term toleransi dakwah bagi ragam ormas Islam di Indonesia sangat beragam. Bagi GP Ansor Ngantru, toleransi dakwah adalah cara pandang kelompok untuk tidak saling menyalahkan terhadap kelompok lain yang berbeda dalam memahami fiqih atau mahzab. Sedangkan intoleran dalam dakwah merupakan tindakan anarkis dengan mengekspresikan sifat kebencian dalam perbedaan. Baginya, ormas Islam di Indonesia harus menanamkan prinsip toleran dalam dakwah dan meninggalkan segala perbuatan yang mengarah pada radikalisme dan kesengsaraan serta kerugian umat.

Micromechanical properties and functional activity of granulocytes when simulating exogenous loading with ATP in vitro
Authors: Skorkina M. Yu. , Shevchenko T. S. , Zhernakova N. I.
Published: March 2021

The micromechanical properties of leukocytes make a certain contribution to the blood flow velocity in the microcirculatory bed, while the micromechanical properties themselves change under the influence of a complex network of purinergic signals.

The aim of the work was to study the micromechanical properties and functional activity of granulocytes in normal conditions and in patients with acute lymphoblastic leukemia when simulating exogenous loading with ATP in vitro.

Materials and methods. Leukocytes were isolated from the blood of patients with acute lymphoblastic leukemia and healthy people. Each sample was divided into a test sample and a control sample. In the test samples, the loading with ATP in vitro was simulated. Leukocytes of the control samples were incubated in the culture medium without the addition of ATP. Young’s modulus and adhesion force were measured using an atomic force microscope in the force spectroscopy mode. The cell surface potential was measured in an atomic force microscope in the Kelvin mode. To assess the functional activity of granulocytes, hypoosmotic tests in vitro and determination of migration activity were used.

Results. In tests with exogenous ATP, both in samples from healthy people and from patients with acute lymphoblastic leukemia, a decrease in the rigidity and potential of the plasma membrane surface, an increase in the adhesive properties of leukocytes and migration activity were found. At the same time, the responses of granulocytes to the osmotic loading were different: for example, in the group of healthy people, the loading with ATP caused cell contraction and a decrease in the use of the membrane reserve by the cell in a hypotonic environment, and in patients with acute lymphoblastic leukemia, it caused an increase in the volume and more intensive use of the membrane reserve in volume regulation.

Conclusion. The revealed effects indicate the leading role of the ATP molecule in the signal transduction mechanisms between blood cells in the microvasculature. The increase in the adhesive properties of the cell surface of granulocytes revealed in the study, in parallel with the increase in their migration activity under the influence of the ATP molecule, can contribute to the development of inflammation in the vessel wall.

Published: March 2021

Introduction.The study was devoted to assessing the effectiveness of laser therapy in the treatment of spondylogenic radiculoischemias. Low-intensity laser therapy and vaporization technology were used.

Aim – to improve treatment and outcomes in patients with compression of the spinal roots in herniated intervertebral discs using various methods of laser therapy.

Materials and methods. In two groups, the results of treatment of 225 patients with clinical manifestations of spondylogenic lumbosacral radiculoischemias were analyzed using laser therapy techniques. In 115 cases (group 1), laser treatment was performed using the method of puncture polychannel laser disk decompression. In 110 patients (group 2), low-intensity percutaneous laser therapy was used. The dynamics of the clinical and neurological manifestations of the disease was recorded: the time of pain syndrome reduction, the dynamics of motor and sensory disorders of the corresponding root, changes in parameters according to the Roland-Morris and Oswestry Disability questionnaire.

Results. In both groups, an improvement in clinical and neurological manifestations was obtained: the intensity of pain syndrome according to VAS decreased in more than 70 % of the observed individuals. A significant improvement in the parameters of vital activity was revealed according to scales with a long-lasting effect (more than 12 months) with an improvement in the blood supply to the spinal roots.

Conclusion. Laser radiation has significant clinical effectiveness; the important parameters are the wavelength and rate of the radiation. Structural-modifying action and improvement of microcirculation (of arterial and venous bed) are achieved. Evaluation of the effectiveness of polychannel laser puncture decompression is advisable using scales and questionnaires. Low-intensity percutaneous laser therapy and monochannel interstitial laser therapy provide a targeted antiedemic and neuroprotective effect with the possibility of dosing and control. The treatment is highly effective and improves the prognosis of the disease.
Book Review: Smart City Citizenship
Authors: Calzada Igor
Published: March 2021

Against the backdrop of the current hyperconnected and highly virialised post-COVID-19 societies, we, ‘pandemic citizens’, wherever we are located now, have already become tiny chips inside an algorithmic giant system that nobody really understands. Furthermore, over the last decade, the increasing propagation of sensors and data collections machines and data collections machines in the so-called Smart Cities by both the public and the private sector has created democratic challenges around AI, surveillance capitalism, and protecting citizens’ digital rights to privacy and ownership. Consequently, the demise of democracy is clearly already one of the biggest policy challenges of our time, and the undermining of citizens’ digital rights is part of this issue, particularly when many ‘pandemic citizens’ will likely be unemployed during the COVID-19 crisis. Amidst the AI-driven algorithmic disruption and surveillance capitalism, this book review sheds light on the way citizens take control of the Smart City, and not viceversa, by revolving around the new book entitled Smart City Citizenship recently published by Elsevier. The book review introduces nine key ideas including how to (1) deconstruct, (2) unplug, (3) decipher, (4) democratise, (5) replicate, (6) devolve, (7) commonise, (8) protect, and (9) reset Smart City Citizenship.

Published: March 2021

Nurse as a profession and caregiver who composed the large portion of healthcare service workers is required to have high expertise in carrying out nursing practice, the speed at work, and high work volume. With these important roles, the income earned by nurses is still in the low category as a healthcare provider that makes nurses feel dissatisfied in their work. The purpose of this study was to describe the workload of nurses, level of work satisfaction and to find out the relationship between the workloads in nursing and the job satisfaction in one private hospital in the west region of Indonesia. This study used a quantitative method with a cross-sectional approach. Data were collected using a questionnaire of nursing workload and nursing job satisfaction on 126 nurses in one private hospital in the west region of Indonesia with a total sampling technique. Univariate and bivariate were conducted to analyze the collected data. This study found that there were 55% of nurses with high workload and 52% of nurses with job dissatisfaction. There was a relationship between workloads to nursing job satisfaction (p-value 0.001). This research recommend the hospitals to re-evaluate nurses job satisfaction, give reward and set excellent and evident career path in nursing.
Los himnos Esna II, 17 y 31: interpretación teológica e integración en el programa decorativo de la fachada ptolemaica del templo de Esna
Authors:   Universidade de Lisboa (Portugal), Fernández Pichel Abraham I.
Published: March 2021

The publications dedicated to the inscriptions on the Ptolemaic façade of the temple of Esna in recent decades have enabled us to advance our knowledge of the complex theologies of this Egyptian sanctuary from the Greco-Roman period. The present paper analyses the configuration in the hymns of the soubassements of the façade (Esna II, 17 and 31) of a complex diptych devoted to the main deities of the region of Esna (Khnum-Ra and Neith, on the one hand, and Shu and Tefnut, on the other) and to the creation of the world and existence. The thematic analogies found with the texts and images that decorate the Ptolemaic façade fully justify their integration into the decorative programme of this area of the temple
Ofrendas en el Inframundo: el Libro de las Doce Cavernas en el Osireion de Abidos
Authors:   Universidad de La Laguna(España), Méndez-Rodríguez Daniel M.
Published: March 2021

The Book of the Twelve Caverns consists of a litany of deities who inhabited these mythical regions of the Beyond. The versatility of its cosmographic nature enabled its use and adaptation to different contexts. It was used in certain liturgical ceremonies in temples and also in a funerary sphere related to the burial equipment of certain deceased individuals in order to help them in their journey through the caverns of the Duat. The version of the composition inscribed in the south chamber of the Osireion in Abydos is, beyond any doubt, the most completed copy hitherto preserved. It can be dated to the reign of Merenptah (c. 1213-1203 BC). The aim of this paper is to present the main features of this example of the book. Its specific features will be highlighted, as well as its textual and iconographic adaptation to the cultic sphere. The absence of differentiation in some aspects to the funerary versions of the book will also be underlined. The composition will be analysed in the architectonical context of the chamber and, at a more general level, in the iconographic programme of the Osirian underground complex. Finally, the relationship with some other sources throughout the history of the book’s transmission will be detailed
Apelaciones, deseos y mensajes para la eternidad. El llamado a los vivos en las estelas abideanas del Reino Medio
Authors: Rosell Pablo M.
Published: March 2021

The appeal to the living refers to some inscriptions left by the deceased on their graves and funerary monuments allowing any visitor to read and recite them in order to perpetuate their name, their memory and guarantee the symbolic provision of offerings. The appeal to the living has been known since the end of the Old Kingdom and can be found throughout the Pharaonic history. In this paper, we will analyse the appeals to the living found in a large number of votive stelae from Abydos. These stelae were set up in Abydos as part of the feasts of the Osiris Mysteries. Based on their analysis, this paper attempts to reveal some questions about these appeals to the living such as: Who was the addressee? What were their intentions? What kind of demands did they use to request? What kind of reward would be offered to the visitors who recite their claims? And how these appeals are registered within the context of the annual pilgrimages for the celebrations of the Osiris Mysteries in Abydos?
Parámetros de clasificación zoológica comparados: la familia Anatidae en egipcio y sumerio
Authors:   Universidad de Valladolid (España), Vives Cuesta Alfonso
Published: March 2021

This study aims to lay the foundations for a further research project in which, through a comparative methodology, a zootechnical compendium of graphic representations linked to semantic content characteristic of the birds in the two main pre-Aristotelian classification traditions of Antiquity, Egypt and Mesopotamia, is carried out in order to establish their points of contact, affinities, possible affiliations and constitutive divergences. Focusing—for space reasons—on some significant species of the Anatidae family, we try to achieve a dual objective: to make a brief description of its possible animal behaviour from iconographic and literary sources, and, in addition, to describe the lexical-graphematic functioning of the determining signs or generic classifiers this class of birds are depicted with in both spellings. This latter aspect will be addressed from a comparative perspective that allows us to shape a kind of basic mental scheme that accounts for the functional and symbolic role that these birds possessed at the core of the symbolic world representation revealed by both spellings. Furthermore, it could help us to understand more accurately the anthropological nucleus that underlies them. The authors of this contribution start from the theoretical principle— already confirmed by recent theoretical studies—that the contrasting study of semantic classifiers can provide valuable information on the categorization and hierarchy of classes of world features represented by the speakers of these languages, particularly as they are underlying cognitive principles and rules that iconically reflect a rather coherent conceptual and spatial microcosm.

Experimental studies of the influence of unit Reynolds number on the laminar-turbulent transition in a supersonic boundary layer of a swept wing with a subsonic leading edge at Mach number 2 are performed. The experiments were performed on a model of a swept wing with a swept angle of the leading edge of 72 degrees and with a 3% profile with a variable chord length in span. The hot-wire measurements showed that a laminar-turbulent transition in a supersonic boundary layer of a swept wing with a subsonic leading edge occurs earlier (~25-30%) than on a model with a supersonic leading edge with the same oncoming flow parameters. It is shown that a change unit Reynolds number insignificant influence the laminar-turbulent transition in the boundary layer of a swept wing with a subsonic leading edge.

This paper presents the results of studying the features of the development of weak shock waves generated by a twodimensional roughness on the wall of the working part of a supersonic wind tunnel in a free flow at a Mach number of 2.5. The measurements were performed with a constant resistance thermoanemometer. It is shown that a twodimensional sticker induces weak shock waves into the free flow. They cause distortion of the average flow, the shape of which corresponds to the N-wave. High-intensity pulsations were recorded in the region of passage of a pair of weak shock waves. With an increase in the unit Reynolds number, the level of distortions of the average flow remains practically constant, but an increase in nonstationary disturbances is observed. It was found that the greatest increase in pulsations caused by Mach waves is observed in the area of the maximum gradient of the average flow. It is found that an increase in the number ReLleads to an expansion of the frequency range of unstable disturbances generated by a pair of weak shock waves.

A Method for Controlling Arrival Time to Prevent Late Arrival by Manipulating Vehicle Timetable Information
Authors: Futami Kyosuke , Terada Tsutomu , Tsukamoto Masahiko
Published: March 2021

Although it is socially and ethically important not to be late for a specified arrival time, late arrivals sometimes happen to people using public transportation. Although many methods aim to smooth a user's movement by providing useful information, there are few approaches to prevent late arrivals due to psychological factors. In this research, to make a user's arrival time earlier and thus prevent late arrival, we propose a method that manipulates time allowance by presenting information based on a psychological and cognitive tendency. We apply this method to a vehicle timetable system for the purpose of preventing public transit users from arriving after a target vehicle's departure time. Our proposed timetable system manipulates the time intervals between a user's target vehicle and other vehicles by introducing fictional elements such as hidden vehicles and inserted fictional vehicles. This method uses the relationship between the time allowance and the departure time interval, and it can make a user desire and accept arriving at a station earlier. We implemented a prototype system and conducted four experiments. The evaluation results confirmed that our proposed method is effective for changing a user's time allowance and actual arrival time.
Information Diffusion Enhanced by Multi-Task Peer Prediction
Authors: Ito Kensuke , Ohsawa Shohei , Tanaka Hideyuki
Published: March 2021

Our study aims to strengthen truthfulness of the two-path mechanism: an information diffusion algorithm to find an influential node in non-cooperative directed acyclic graphs (DAGs). This subject is important because the two-path mechanism ensures only weak truthfulness (i.e., nodes are indifferent between reporting true or false out-edges), which restricts node selection accuracy. To enhance the mechanism, we employed an additional reward layer based on a multi-task peer prediction, where an informative equilibrium provides strictly higher rewards than any other equilibrium in virtually all cases (strong truthfulness). Rewards, which are derived from a comparison of each report, encourage a node to report true out-edges without affecting its own probability of being selected by the original two-path mechanism. We have also experimentally confirmed that our proposed {\em strongly truthful two-path mechanism} can sufficiently elicit true out-edges from each node.
A Parallelizing Method for Generation of Voronoi Diagram Using Contact Zone
Authors: Okahana Yuuhi , Gotoh Yusuke
Published: March 2021

Due to the recent popularization of the Geographic Information System (GIS), spatial network environments that can display the changes of spatial axes on mobile devices are receiving great attention. In spatial network environments, since a query object that seeks location information selects several candidate target objects based on the search conditions, we often use a k-nearest neighbor (kNN) search, which seeks several target objects near the query object. However, since a kNN search needs to find the kNN by calculating the distance from the query to all the objects, the computational complexity might become too large based on the number of objects. To reduce this computation time in a kNN search, many researchers have proposed a search method that divides regions using a Voronoi diagram. However, since conventional methods generate Voronoi diagrams for objects in order, the processing time for generating Voronoi diagrams might become too large when the number of objects is increased. In this paper, we propose a generation method of the Voronoi diagram by parallelizing the generation of Voronoi regions using a contact zone. Our proposed method can reduce the processing time of generating the Voronoi diagram by generating Voronoi regions in parallel based on the number of targets. Our evaluation confirmed that the processing time under the proposed method was reduced about 15.9\% more than conventional methods that are not parallelized.
Partial Annotation Scheme for Active Learning on Named Entity Recognition Tasks
Authors: Kobayashi Koga , Wakabayashi Kei
Published: March 2021

Active learning is a promising approach to alleviate the expensive annotation cost for making training data on named entity recognition (NER) tasks. However, since existing active learning methods on NER tasks implicitly assume the full annotation scheme of which the unit of an annotation request is the whole sentence, the efficiency of the data instance selection is limited. In this paper, we propose a new active learning method based on a partial annotation scheme, which selects a part of the sentences to be annotated and asks human annotators to label a specific part of the target sentences. In the experiment, we show that the partial annotation scheme can quickly train the proposed point-wise prediction model compared to the existing active learning methods on NER tasks.
Return probability and self-similarity of the Riesz walk
Authors: Hanaoka Ryota , Konno Norio
Published: March 2021

The quantum walk is a counterpart of the random walk. The 2-state quantum walk in one dimension can be determined by a measure on the unit circle in the complex plane. As for the singular continuous measure, results on the corresponding quantum walk are limited. In this situation, we focus on a quantum walk, called the Riesz walk, given by the Riesz measure which is one of the famous singular continuous measures. The present paper is devoted to the return probability of the Riesz walk. Furthermore, we present some conjectures on the self-similarity of the walk.

Published: March 2021

The decarboxylation of Δ9-tetrahydrocannabinolic acid (THCA) plays pivotal role in the potency of medical cannabis and its extracts. However, the literature data point out substantial variations in the process reaction rate and conversion efficacy due to variability of the temperature, heat transfer efficacy, raw material attributes, consequently resulting in incomplete decarboxylation, cannabinoid content decrease due to decomposition, evaporation, and possible side reactions. Our present work aims to draw attention to mid-infrared (MIR) spectroscopy for in-situ monitoring and decipher the THCA decarboxylation reaction in the solid state. The initial TG/DTG curves of THCA, for a first time outlined the solid-solid decarboxylation dynamics, defined the endpoint of the process and the temperature of the maximal conversion rate, which aided in the design of the further IR experiments. Temperature controlled IR spectroscopy experiments were performed on both THCA standard and cannabis flower by providing detailed band assignment and conducting spectra-structure correlations, based on the concept of functional groups vibrations. Moreover, a multivariate statistical analysis was employed to depict the spectral regions of utmost importance for the THCA→THC interconversion process. The principal component analysis model was reduced to two PCs, where PC1 explained 94.76% and 98.21% of the total spectral variations in the THCA standard and in the plant sample, respectively. The PC1 plot score of the THCA standard, as a function of the temperature, neatly complemented to the TG/DTG curve and enabled determination of rate constants for the decarboxylation reaction undertaken on several temperatures. Consequently, a progress in elucidation of kinetic models of THCA decarboxylation, fitting experimental data for both, solid state standard substance and a plant flower, was achieved. The results open the horizon to promote an appropriate process analytical technology (PAT) in the outgrowing medical cannabis industry.

Low Density Interior in Supercooled Aqueous Nanodroplets Expels Ions to the Subsurface
Authors: Malek Shahrazad Moh'd , Saika-Voivod Ivan , Consta Styliani
Published: March 2021

The location of a single and multiple ions in aqueous droplets plays a key role in chemical reactivity of atmospheric and man-made aerosols. We report direct computational evidence that in supercooled aqueous nanodroplets a lower density core of tetrahedrally coordinated water molecules expels the sodium ions to a higher density and more disordered subsurface. In contrast, at ambient temperature the single Na+ density is higher in the core region and has a broad maximum at the droplet's center of mass. We analyse the expulsion of a single ion in terms of a general reference electrostatic model that we have developed. The energy of the system in the analytical model is expressed as the sum of electrostatic and surface energy of a fluctuating droplet. The model predicts that the energy associated with the distance of the ion from the droplet's center of mass is quadratic in this distance. We name thiseffect "electrostatic confinement". The predictions of the model are consistent with the simulations fndings for a single Na+ ion at ambient conditions. Our results assist in understanding the mechanisms of charging of macromolecules in spray-based ionization methods used in native mass spectrometry and the physical chemistry of atmospheric aerosols.
A Concise Synthesis of a Methyl Ester 2-Resorcinarene: A Chair-Conformation Macrocycle
Authors: Reynolds Michael R. , Pick Fraser S. , Hayward John , Trant John F.
Published: March 2021

Anions are important hydrogen bond acceptors in a range of biological, chemical, environmental and medical molecular recognition processes. These interactions have been exploited for the design and synthesis of ditopic resorcinarenes as the hydrogen bond strength can be tuned through the modification of the substituent at the 2-position. However, many potentially useful compounds, especially those incorporating electron-withdrawing functionalities, have not been prepared due to the challenge of their synthesis: their incorporation slows resorcinarene formation that is accessed by electrophic aromatic substitution. As part of our broader campaign to employ resorcinarenes as selective recognition elements, we need access to these specialized materials, and in this article we report a straightforward synthetic pathway for obtaining a 2-(carboxymethyl)-resorcinarene, and resorcinarene esters in general. We discuss the unusual conformation it adopts, and propose that this arises from the electron-withdrawing nature of the ester substituents that renders them better hydrogen bond acceptors than the phenols, ensuring that each of those acts as a donor only. DFT calculations show that this conformation arises as a consequence of the unusual configurational isomerism of this compound and interruption of the archetypal hydrogen bonding by the ester functionality.
Revisiting the Electronic Structure of Cobalt-Porphyrin Nitrene and Carbene Radicals with NEVPT2-CASSCF Calculations: Doublet versus Quartet Ground States
Authors: van Leest Nicolaas P. , de Bruin Bas
Published: March 2021

Cobalt-porphyrin complexes are established catalysts for carbene and nitrene radical group transfer reactions. The key carbene, mono- and bis-nitrene radical complexes coordinated to [Co(TPP)] (TPP = tetraphenylporphyrin) have previously been investigat-ed with a variety of experimental techniques and supporting (single-reference) DFT calculations that indicated doublet (S = ½) ground states for all three species. In this contribution we revisit their electronic structures with multireference NEVPT2-CASSCF calculations to investigate possible multireference contributions to the ground state wavefunctions. The carbene ([CoIII(TPP)(•CHCO2Et)]) and mono-nitrene ([CoIII(TPP)(•NNs)]) radical complexes were confirmed to have uncomplicated doublet ground states, although a higher carbene or nitrene radical character and a lower Co‒C/N bond order was found in the NEVPT2-CASSCF calculations. Supported by EPR analysis and spin counting, paramagnetic molar susceptibility determination and NEVPT2-CASSCF calculations, we report that the cobalt-porphyrin bis-nitrene complex ([CoIII(TPP•)(•NNs)2]) has a quartet (S = 3/2) spin ground state, with a thermally assessable multireference & multideterminant ‘broken-symmetry’ doublet spin excited state. A spin flip on the porphyrin-centered unpaired electron allows for interconversion between the quartet and broken-symmetry doublet spin states, with an approximate 10- and 200-fold higher Boltzmann population of the quartet at room tempera-ture or 10 K, respectively.

Authors: Abdulmaged Enas A , Abdul Lateef Thair
Published: March 2021

Background:Temporomandibular joint (TMJ) problems refer to a group of heterogeneous pain and dysfunction conditions involving the mastication, reducing life quality of the patients. Arthrocentesis is a simple and less invasive surgical method for the treatment of inflammatory-degenerative disease than other conservative procedures and better than arthroscope. This clinical study aimed at evaluating the benefit of arthrocentesis with injection of hyaluronic acid in the management of inflammatory-degenerative disease of the TMJ. Material and methods: Eighty consecutive patients were enrolled in this study with pain symptoms of TMJ, insufficient masticatory efficiency during function and limitation of mouth opening; they were assessed with clinical examination and approved with computed tomography scan. Arthrocentesis was done by inserting 18 gauge needles in the upper joint compartment, lavage by normal saline solution and at the end of the procedure 1ml of hyaluronic acid (HA) was injected. Intensity of the TMJ pain and masticatory efficiency was analyzed by visual analog scale (VAS), maximum mouth opening (MMO) was assessed by a ruler. All the assessed parameters were measured before the procedure then 1 and 4 months later. Results: During 5 months follow-up, comparison of the obtained results showed reduction in pain at chewing and rest 87.5%, improvement in mouth opening 100% and significant improvement in masticatory efficiency 87.5% of patients. Conclusion: The procedure of arthrocentesis with Sodium Hyaluronate injection, used in patients who suffered from inflammatory-degenerative disease (IDD), showed therapeutic benefits, simplicity, safety, patient satisfaction, lack of significant side effects and complications.

The self-esteem, self-image, and subsequently self-worth of young consumers all around the globe, are determined by unsustainable consumption habits. This is equally true for Muslim youth who are as vulnerable to the pressure of building their self-image as consumers. This has led to adverse effects on the ecosystem and therefore, goes against the United Nation’s sustainable development goals (Goal no. 6,7,11-15). This paper argues that by changing the criterion to gauge and establish their self-image, self-esteem, and self-worth, we can influence the degree of sustainability of the consumption patterns of young Muslim individuals. This would subsequently undo the undue pressure on the ecosystem and reduce the damage. This paper explores how the prevalent criteria of determining self-esteem and self-worth are rooted in unsustainable consumerism, trapping the planet’s ecosystem in an ever-expanding vicious cycle of production, consumption, and waste. The paper recommends the Islamic alternative of determining one’s self-worth, which then buttresses one’s self-confidence and self-esteem. The Islamic concept of self, unlike its modern counterpart, is not dependent on extrinsic factors, such as products and services acquired and consumed by an individual, but on intrinsic factors lying within each individual. Taqw `a (God-consciousness and mindfulness leading to virtuosity), qan¯a‘at (contentment with what you already have), tawakkul (trust in the grace of Allah), tashakkur (gratitude), and zuhd (frugality) are key concepts and behavioral tools to bring the required transformation to the consumption patterns of Muslims, especially youth. The paper proposes ways to promote the cultivation of an Islamically informed self that derives its worth from virtuosity. This alternative Islamic self-image is to be propagated through education (both at the religious institutions and conventional universities) and Islamic entrepreneurship.

The Dark Triad in the Workplace Research is an underinvestigated avenue of research. This conceptual study proposes the supervisors’ dark triad personality as an antecedent to their abusive supervision. The study suggests that the supervisor’s abusive behavior would trigger burnout and counterproductive work behaviors among the employees that are caused by negative personality traits i.e. dark triad. The study further proposes that Islamic Work Ethics may play a critical role to cope up with these negative workplace behaviors due to its nature of a buffering agent. Finally, the study concludes with important implications of Islamic Work Ethics towards new avenues of research in Dark Triad personality and its hazardous effects in the workplace.

This research article presents the main results of zoning of the Kemerovo Oblast based on the level of technogenic load and environmental factor. Based on the analysis of a huge amount of statistical material, information data obtained from government reports, regional reports, strategies for socio-economic development, scientific publications, synthesized multispectral shooting (multispectral images), an assessment was made and relationships were established between the negative impact on the environment and its impact on people's lives of the region with different levels of technogenic load. The relationship between the ecological capacity and the negative impact on the environment is also considered, depending on the volume of coal production in the territory of Kuzbass (the Kuznetsk Basin). The raw material region was ranked according to the area of disturbed lands using synthesized multispectral analysis of space images. As a result of the comprehensive analysis, it was revealed that all municipalities with a high anthropogenic load are characterized by a decrease in environmental indicators of the sustainability of the development of the territory and an increase in negative consequences of both a medico-demographic and socio-economic nature. Analysis of the dynamics of coal mining and emissions of pollutants into the atmosphere showed a proportional relationship between an increase in coal production and an increase in indicators for cancer. It was also revealed that the overall level of diseases in the territories of intensive technogenesis is almost 2 times higher than in areas with a low level of technogenesis. Another tendency was found in urban districts with a high technogenic load – the average annual quantitative growth of negative medical and demographic indicators is proportional to the growth of coal production. Based on this, the author considered various ways to reduce the level of anthropogenic impact on the environment of the Kemerovo Oblast and gave general recommendations for improving the ecological situation in this region. The visualized result of this scientific work is the schematic maps, which reflect the ecological zoning of the region's territory according to the level of anthropogenic load.
