Detectability of the Yarkovsky Effect in the Main Belt
Authors: Hung Denise , Tholen David J. , Farnocchia Davide , Spoto Federica
Published: November 2023

We attempt to detect a signal of Yarkovsky-related acceleration in the orbits of 134 main belt asteroids (MBAs) we observed with the University of Hawai’i 88 inch telescope, supplemented with observations publicly available from the Minor Planet Center and Gaia Data Release 3. We estimated the expected Yarkovsky acceleration values based on parameters derived through thermophysical modeling, but we were not able to find any reliable detections of Yarkovsky in our sample. Through tests with synthetic observations, however, we estimated the minimum observational arc length needed to detect the Yarkovsky effect for all of our sample MBAs, which in nearly every case exceeded the current arc length of the existing observations. We find that the Yarkovsky effect could be detectable within a couple of decades of discovery for a 100 m MBA assuming 0.″1 astrometric accuracy, which is at the size range detectable by the upcoming Vera Rubin Observatory Legacy Survey of Space and Time.
Dynamical Interactions and Mass Loss within the Uranian System
Authors: Kane Stephen R. , Li Zhexing
Published: November 2023

The origin and evolution of planetary rings and moons remains an active area of study, particularly as they relate to the impact history and volatile inventory of the outer solar system. The Uranian system contains a complex system of rings that are coplanar with the highly inclined planetary equator relative to the orbital plane. Uranus also harbors five primary regular moons that play an important role in the distribution of material that surrounds the planet. Here we present the results of a dynamical simulation suite for the Uranian system, intended to explore the interaction between the five primary regular moons and particles within the system. We identify regions of extreme mass loss within 40 planetary radii of Uranus, including eccentricity excitation of particle orbits at resonance locations that can promote moonlet formation within the rings. We calculate a total dynamical particle mass-loss rate of 35% within 0.5 × 106yr and 40% mass loss within 107yr. We discuss the implications for postimpact material, including dynamical truncation of stable ring locations and/or locations of moon formation promoted by dynamical excitation of ring material.

Published: November 2023

A taxonomic revision of Mayodendron Kurz (Bignoniaceae) in Thailand is presented. One species, Mayodendron igneum (Kurz) Kurz, is enumerated with updated morphological description, morphological differences with the related species and illustrations, together with notes on distributions, a distribution map, habitats and ecology, phenology, conservation assessments, etymology, vernacular names, uses and specimens examined. The specimen Brandis 1357 at HBG [HBG522936] is lectotypified here for M. igneum. This species has a conservation status of Least Concern (LC). The leaflet laminas and wood anatomy and pollen morphology of this species are also reported in this study. M. igneum has bifacial leaflets, cyclocytic stomata, prismatic crystals in parenchyma around the vascular tissue and epidermal cells on both leaflet surfaces and its wood has diffuse-porous, biseriate, sometimes uniseriate, triseriate, tetraseriate heterocellular rays or uniseriate homocellular rays, with the procumbent cells up to 30 cells long. M. igneum has prolate-spheroidal or subprolate pollen shapes, small to medium sized, 19–25 µm in polar axis, 18–23 µm in equatorial axis, heterobrocate exine sculpturing. The pollen aperture patterns are classified as 4 types: typical tricolpate, 3-syncolpate with oblique colpi, 4-syncolpate and 6-pantocolpate.
A forgotten collector: Archdeacon Smythe and his collection of British watercolours in New Zealand
Authors: Sippel Annika
Published: November 2023

Francis Henry Dumville Smythe (1873–1966), a humble clergyman from England, spent a lifetime amassing his private collection of British watercolours. During the 1950s, he decided to gift the bulk of them to two art institutions in New Zealand – Dunedin Public Art Gallery and the National Art Gallery in Wellington. They were welcomed with open arms and celebrated as “the finest collection of water colour pictures in the Southern Hemisphere.” However, they soon fell out of favour as shifting aesthetic tastes and calls for a new national identity dominated the art scene in New Zealand during the latter half of the twentieth century. This paper will examine Smythe’s collecting habits and tastes in art, as well as the formation, gifting and reception of the collection in Wellington and Dunedin. It is based on two chapters from the author’s PhD thesis “A Matter of Taste: The Fate of the Archdeacon Smythe Collection of British Watercolours in New Zealand” (2021).

Abstract

A recent molecular phylogeny of the agamid genusPseudotrapelus, distributed in the rocky areas of North Africa and the Arabian Peninsula, revealed the presence of a genetically distinct lineage around the city of Riyadh in central Saudi Arabia. With the inclusion of additional specimens, we were able to describe this lineage as a new species,P. tuwaiqensissp. nov., confined to the Tuwaiq Escarpment, thus endemic to central Saudi Arabia. Our results of morphological examinations and molecular analyses, using three mitochondrial (COI, 16S, ND4-tRNAs) and two nuclear (c-mos, MC1R) gene fragments, show the new species is genetically differentiated and phylogenetically close toP. sinaitusandP. chlodnickii.
Le mutisme de l’enfant comme un écho narratif lointain de la dialectique entre l’être et l’existence
Authors: Golse Bernard
Published: November 2023

L’auteur rappelle tout d’abord la distinction entre le sentiment d’être et le sentiment d’exister, avant de situer l’avènement du langage entre acquisitions et apprentissages. La crise des deux ans et demi marque le passage entre le temps des acquisitions et celui des apprentissages, et il apparaît finalement que le langage s’acquiert plus qu’il ne s’apprend stricto sensu. Après quoi, l’article s’achève sur la question du mutisme de l’enfant, qui peut parfois être considéré comme une narrativité différée des difficultés qui avaient marqué chez le tout-petit son passage de l’être à l’existence, soit son processus d’accès à l’intersubjectivité.

Authors: Zarate-Perez Eliseo , Grados Juan , Rubiños Santiago , Grados-Espinoza Herbert , Astocondor-Villar Jacob
Published: November 2023

Solar energy is one of the most important renewable energy sources due to its wide availability and applicability. One way to use this resource is by building-integrated photovoltaics (BIPV). Therefore, it is essential to develop a scientific map of BIPV systems and a comprehensive review of the scientific literature that identifies future research directions. For that reason, the bibliometric research methodology enables the quantification and evaluation of the performance, quality and influence of the generated maps and their elements. In this regard, an analysis of the scientific production related to BIPV, indexed from 2001 to 2022, was carried out using the Scopus database. This was done using a scientific mapping approach via the SciMAT tool to analyze the co-occurrence of terms through clustering techniques. The BIPV was integrated with the themes of buildings, investments, numerical models, office buildings, photovoltaic modules, roofs, solar cells and zero-energy buildings. As photovoltaic technology progresses, the production of flexible PV elements is increasing in lieu of silicon substrate-based PV elements, and this is of current scientific interest. The evaluations of BIPVs in various climatic contexts are encouraging in warm and sunny climates. BIPVs demonstrated high-energy generation, while in temperate climates, BIPV windows exhibited a reduction in heating and cooling loads, indicating notable efficiency. Despite significant benefits, BIPVs face challenges such as upfront costs, integration complexities and durability concerns. Therefore, silicon solar cells are considered a cross-cutting theme within the BIPV research field. It is highlighted that this study provides a comprehensive scientific mapping and critical review of the literature in the field of BIPV systems. This bibliometric analysis not only quantifies the performance and quality of the generated maps but also identifies key thematic areas that have evolved.

A Review of Joint Applications of IoT and Deep Learning
Authors: Tang Wenhao , Wang Jiaji
Published: November 2023

In recent years, graph convolutional networks (GCNs) have been widely used in image classification tasks. The combination of GCNs and the Internet of Things (IoT) has led to the development of some branches of the latter. This paper explores cases where convolutional neural networks and GCNs are combined with IoT to achieve better results. This paper also focuses on discussing the semi-supervised classification task of GCNs. The innovative approach explored for innovative GCNs dealing with semi-supervised classification tasks lies in optimizing the GCN topology and using graph convolutional operations in the topological space for better training of the model.
Une année à la Cour Suprême des États-Unis (2022-2023) : après le séisme, les répliques ?
Authors: Morri Johann
Published: November 2023

Après une année 2021-2002 marquée par le choc du revirement sur le droit à l'avortement, l’année 2022-2023 n’a pas été une simple année de transition pour la Cour suprême des États-Unis. Poursuivant sur sa lancée, la Cour a rendu des décisions importantes qui s’inscrivent dans la philosophie judiciaire conservatrice de sa « super majorité » : elle a ainsi porté un coup d'arrêt à l'affirmative action à l'université et affaibli la législation anti-discrimination en admettant le refus de certaines entreprises de fournir des services pour des mariages entre personnes de même sexe. Mais ce tableau mérite d’être nuancé car la Cour a aussi rendu, sur des sujets importants comme le droit électoral ou l'équilibre entre propriété intellectuelle et liberté d'expression, des décisions qui montrent que sa majorité conservatrice ne constitue pas toujours un bloc homogène de sorte que les clivages au sein de la Cour ne correspondent pas systématiquement à sa division idéologique.
Securing End User Computing Environments Using Blockchain
Authors: Gupta Chabi
Published: November 2023

COVID-19's phenomenal effect has expedited the adoption of digital technologies over several years, indicating that several of these breakthroughs are here to stay. Several enabling technologies are currently being implemented as major solutions for improving and responding to the pandemic's numerous issues, with blockchain being one of the preferred solution options. Blockchain can be used to re-structure processes, resulting in most effective operational and business models (e.g., democratising quality cancer detection with advanced artificial intelligence based radiomics technologies). The authors posit here that while there is a lot of anticipation about using blockchain to improve business capabilities, the lessons learned from the many pilots and proofs of concept so far should be considered. The necessity for a structured, formal decision-making process, based on good business logic and an awareness of the problem's process lifecycle, is however critical. Blockchain is a means to an end, not an end in and of itself.

Authors: Martins Braga Ascensão Maria , Vieira Paulo Alexandre
Published: November 2023

One of the most important concerns of companies is engagement with stakeholders. One of the main ways of engaging is using gamification. To create engagement is the principal aim of a gamification system. In this work, and from literature, the authors survey how it has gamified the relationship between companies and stakeholders. The aim is to gather data to create a dataset for training an artificial neural network model. Among the artificial intelligence (AI) models, this kind of model has been the one that has been shown to increase human analytical capacity and is responsible for the emergence of generative AI. The final aim of this work is to create a generative AI that enables the design gamification system to create engagement between stakeholders and companies in the more diverse areas. This AI will be used as a service in a platform as a service (PaaS), where companies can get the best way to engage the stakeholders.

A Cross-sectional Study to Correlate the Levels of High Sensitivity C-Reactive Protein and Size of Infarct in Ischemic Stroke
Authors: Mohan Gurinder , Kaur Harsimran , Narang Nisha
Published: November 2023

Background:

Inflammation plays a major role in the pathophysiology of acute cerebrovascular accidents and nowadays, a newer and more sensitive method to test for lower circulating levels of C-reactive protein (CRP), highly sensitive CRP (hsCRP), is being used in apparently healthy individuals for risk assessment. Previous studies show that CRP strongly correlates with stroke severity and independently predicts mortality and recurrence in patients with acute ischemic stroke. The aim of this study was to evaluate the relationship between inflammatory marker-hsCRP and stroke severity by means of volumetric measurement of infarct size.

Methods:

In this cross-sectional study, 60 patients with acute ischemic stroke were included who were diagnosed using the National Institute of Health Stroke Scale (NIHSS) and magnetic resonance imaging (MRI) scans. Serum levels of hsCRP were measured. Lesion volumes (in ml) were calculated by multiplying slice thickness (4–5 mm) by the total lesion area and divided into quartiles. The relationship between hsCRP levels and diffusion-weighted imaging infarct volume quartiles was examined.

Results:

Ischemic stroke was predominantly seen in the male population (n = 36, 60%) and the sixth decade of life. The mean NIHSS score of the study population was 10.68 ± 1.068. The mean (± standard deviation [SD]) level of serum hsCRP was 6.69 ± 7.072 mg/L. The mean (± SD) stroke volume was 8.64 ± 14.21 ml. The correlation between hsCRP and the size of infarct on three-dimensional MRI brain scan was statistically highly significant (P < 0.001, r = 0.667).

Conclusions:

Higher hsCRP levels were associated with larger infarct volumes in acute ischemic stroke suggesting that elevated hsCRP levels, may serve as a helpful serologic marker in the evaluation of the severity of acute ischemic stroke.

On the detailed structure of quantum control landscape for fast single qubit phase-shift gate generation
Authors: Volkov Boris Olegovich , Pechen Alexander Nikolaevich
Published: November 2023

In this work, we study the detailed structure of quantum control landscape for the problem of single-qubit phase shift gate generation on the fast time scale. In previous works, the absence of traps for this problem was proved on various time scales. A special critical point which was known to exist in quantum control landscapes was shown to be either a saddle or a global extremum, depending on the parameters of the control system. However, in case of a saddle,
the numbers of negative and positive eigenvalues of the Hessian at this point and their magnitudes have not been studied. At the same time, these numbers and magnitudes determine the relative ease or difficulty for practical optimization in a vicinity of the critical point. In this work, we compute the numbers of negative and positive eigenvalues of the Hessian at this saddle point and, moreover, give estimates on magnitude of these eigenvalues. We also significantly simplify our previous proof of the theorem about this saddle point of the Hessian
(Theorem 3 in [22]).
Mechanisms of action of natural products on type 2 diabetes

Published: November 2023

The complication of diabetes, which is known as diabetic foot ulcer (DFU), is a significant concern due to its association with high rates of disability and mortality. It not only severely affects patients’ quality of life, but also imposes a substantial burden on the healthcare system. In spite of efforts made in clinical practice, treating DFU remains a challenging task. While mesenchymal stem cell (MSC) therapy has been extensively studied in treating DFU, the current efficacy of DFU healing using this method is still inadequate. However, in recent years, several MSCs-based drug delivery systems have emerged, which have shown to increase the efficacy of MSC therapy, especially in treating DFU. This review summarized the application of diverse MSCs-based drug delivery systems in treating DFU and suggested potential prospects for the future research.
Professionalisation of Andragogical Staff Through a University Study Programme in the Republic of Croatia
Authors: Tomac Lucija , Zovko Anita
Published: November 2023

Despite a rich tradition of institutional adult education and relatively continuous development of andragogical theory and practice, the Republic of Croatia has only adopted strategic and legal frameworks that have created the conditions for the professionalisation of adult education staff in the last twenty years. This paper aims to present the andragogical thought, legislative framework, and andragogy study programme in Croatia. The need for the university education of andragogues stems from research results that indicate many employers prefer highly educated staff in this field. To respond to current needs, the Faculty of Humanities and Social Sciences in Rijeka is going to implement a University Part-Time Graduate Study in Andragogy programme designed in accordance with ten years of positive experience in adult education in the Republic of Croatia, modern achievements in andragogical theory and practice, and based on the Croatian Qualification Frame.
Razvoj izobraževanja odraslih in andragogike na Slovenskem
Authors: Govekar Okoliš Monika
Published: November 2023

The paper deals with adult education in Slovenia in individual periods from the end of the 18th to the 21st century. The research method is historical analysis. The purpose of the qualitative research is to show how the institutional and mass education of adults developed in individual periods, how society influenced adult education, and the development of andragogical ideas and andragogy. The most important institutions, their purpose, the mass education of adults, and individuals who introduced new andragogical ideas and efforts to develop andragogy are presented. We found that the development of adult education was different over time, depending on the development of society, economy, and politics. Andragogical ideas were in evidence at the end of the 18th and in the 19th century. The theory of adult education originated at the beginning of the 20th century. A new scientific discipline, andragogy, developed in the second half of the 20th century from social needs for new knowledge, experts and from research into the practice of adult education. The first study programme in andragogy was established at the Faculty of Arts of the University of Ljubljana.
Questioning Assumptions About Developing an Andragogy Study Program in Bosnia and Herzegovina
Authors: Isanović Hadžiomerović Amina
Published: November 2023

This paper analyses how the key actors involved (university professors, policy makers, and practitioners) perceive the need for launching an andragogy study program in Bosnia and Herzegovina (BiH). Drawing on the social field concept, the central argument posits that the perceptions of the three groups are shaped by their respective positions and interests concerning adult learning and education (ALE). The research methodology includes an analysis of university curricula and qualitative surveys based on the model of the problem-centred interview (PCI). The results show inter-group differences and intra-group congruence. University professors support the idea of launching an independent andragogy study program but have different visions of the implementation model. Policy makers and practitioners show less awareness of the need for such a program and for different reasons. The practitioners’ opinion is that the relevant competencies can be obtained through non-formal or work-based learning, while policy makers cite lower interest in studying social sciences.

A New Converter Topology with PV/Battery Hybrid System with Energy Management Control Strategy
Authors: Kavali Sanjay Bhargav and D Ravi Kishore
Published: November 2023

This Paper aimed at developing a standard procedure for the design of large-scale institutional grid-connected solar PV
systems using the roofs of buildings and car parks. Grid-connect PV systems with battery back-up (sometimes referred to
as uninterrupted power supply or hybrid solar PV systems) are becoming increasingly popular. Grid-connected systems
do not need batteries which reduces considerably initial capital costs and energy costs. For a comparable load, grid -tied
systems use smaller PV arrays than stand-alone systems. In order to address this issue, a two-stage stand-alone scheme
consisting of a novel transformer coupled dual-input converter llowed by a conventional full-bridge inverter is proposed.
The proposed converter can realize maximum power point tracking and battery charge control while maintaining the
proper voltage level at the load terminal. A suitable control strategy for the proposed converter devised for manipulating
the converter to realize the first two aforementioned objectives, while the third objective is achieved by employing a
conventional proportional integral (PI) controller to control the output voltage of the five level inverter through sinusoidal
pulse width modulation
PQ Theory Based Power Quality Improvement in Distribution Level with D-STATCOM
Authors: Bellapukonda Sravani, B Kavyasanthoshi and D Ravi Kishore
Published: November 2023

The Transient response of the distribution static compensator (DSTATCOM) is very important while
compensating rapidly varying unbalanced and nonlinear loads. Any change in the load affects the dc link
voltage directly. The sudden removal of load would result in an increase in the dc link voltage above the
reference value where as a sudden increase in the load would reduce the dc link voltage below its reference
value. The proper operation of DSTATCOM requires variation of the DC link voltage within the prescribed
limits. Conventionally, a proportional-integral (PI) controller is used to maintain the dc-link voltage to the
reference value. It uses the deviation of the capacitor voltage from its reference value as its input. However,
the transient response of the conventional PI dc-link voltage controller is slow. In this paper, a fast acting
dc-link voltage controller based on the energy of the dc-link capacitor is proposed and proposed shunt
controller method by using PQ-Theory. Mathematical equations are given to compute the gains of the
conventional controller based on the fast-acting dc-link controllers to achieve similar fast transient response.
The detailed simulation studies are carried out to validate the proposed controller..
SYNTHESIS, CHARACTERIZATION AND XRD ANALYSIS OF COPPER (II) AND IRON (II) COMPLEXES OF BENZOIC ACID HYDRAZIDE.
Authors: Odih C. , Amadi O. K. , Ngwu C. M. , Ubani L. O. C.
Published: November 2023

Schiff bases are an important class of organic compounds, which play an important role in medicinal and pharmaceutical applications. Metal complexes formed by the reactions of keto forms of Benzoic acid hydrazide (BAH) with Cu(II) and Fe(II) sulphate ions were prepared and characterized by X-ray Diffraction analysis (XRD), Fourier Transform Infrared (FTIR) and electronic absorption spectra studies. The results showed that the hydrazides reacted with the metal salts in 1:2 molar ratio in all the complexes and acts as neutral bidentate ligands. The X-ray diffraction (XRD) pattern of the metal complexes provides a detailed comparative account of the behavior of the metal complexes of hydrazide ligand metal complexes. The pattern of BAH complexes shows the main characteristics peak and broad shoulder. In view of the relative half value width (FWHM), it may be concluded that the BAH-Cu is partially crystalline and while the BAH-Fe shows an amorphous nature. The broad characteristic peak indicates the amorphous nature of the polymers. The solubility test on the ligands and its metal (II) complexes revealed their solubility in ethanol and dimethylsulphoxide (DMSO). The infrared spectra of the hydrazide showed that ?(C=O), the carbonyl stretching mode, the coupling between the in-plane bending ?(N-H) and ?(C-N) and the stretching frequency for the amino group ?(NH2) all experienced shifts to lower wave numbers in the complexes suggesting the coordination of the moieties to the metal ions. The electronic absorption spectra of Cu(II) complexes showed absorption band located at 36,496 cm-1 showing a tetrahedral geometry while Fe(II) BAH and BAH ligand show absorption band at a shoulder around 16051 cm-1 with 4A2 ? 4T1 (P) respectively consistent with a four coordinate tetrahedral geometry.

Published: November 2023

La programación de horarios se clasifica como un problema combinatorio para el que existen múltiples alternativas de solución incluyendo entre ellas la programación entera. Sin embargo, el modelado de reglas operativas y el tamaño de problemas reales hace que su uso no sea común comparado con otras técnicas. El presente artículo propone un modelo de programación entera (IP), que aborda el problema de programación de horarios conformado por variables asociadas con franjas horarias, asignatura y docente asignado. También se incluyen parámetros como número de franjas horarias mínimas y máximas a impartir por el docente, tiempo de franja horaria, disponibilidad de docente, salones disponibles y costo estimado de insatisfacción generado por el horario asignado. En el modelo se integran siete restricciones duras y diecisiete blandas que proporcionan mayor calidad a la solución final de horarios. Se valida el modelo IP con una función objetivo global, en el que se reportan experimentos y resultados obtenidos en instancias reales de la Universidad de la Salle (ULS). El nuevo enfoque de solución ofrece mejoras en los horarios finales, así como la interacción con los usuarios durante su construcción. Finalmente, en las conclusiones del trabajo se discute el diseño y desarrollo de un sistema que brinda soporte a las decisiones, referenciando sugerencias para futuros desarrollos.
Teletrabajo y clima ético. El efecto mediador de la autonomía laboral y del compromiso organizacional
Authors: Santiago Torner Carlos
Published: November 2023

Este estudio examina la asociación entre teletrabajo y clima ético considerando la intervención de la autonomía laboral y del compromiso organizacional. La muestra incluye  448 empleados pertenecientes al sector eléctrico colombiano. Los datos se recopilan mediante una encuesta online y se analizan a través de un esquema de mediación múltiple. Los resultados revelan que el teletrabajo y sus beneficios se relacionan con los climas éticos benevolente y de principios, pero no con el egoísta. De hecho, el teletrabajo emerge desde lo individual pero su flexibilidad busca acercar a las personas y apoyar el trabajo de equipo. Asimismo, un entorno virtual confiere al empleado la capacidad de trabajar de una forma autónoma lo que se asocia con una mayor productividad e igualdad de género junto con un menor conflicto trabajo-familia. La autonomía, se traduce en satisfacción laboral lo que limita las intenciones de rotación y las ausencias no justificadas. Por otro lado, las decisiones autónomas se relacionan con los diferentes climas éticos, a excepción del egoísta, pues la esencia de la autogestión busca respetar las normas y reglamentos que un clima egoísta tiende a infringir. Finalmente, el teletrabajo al influir positivamente en los intereses personales activa el compromiso afectivo y normativo, por igual, pero incide en menor medida sobre el compromiso de continuidad. El compromiso organizacional se relaciona positivamente con el clima ético al igual que con sus tres dimensiones: egoísta, benevolente y de principios. No obstante, el clima egoísta no repercute en las escalas afectiva y normativa del compromiso.
ROYAL IMAGERY OF KING MILUTIN IN HISTORICAL CONTEXT REVISITED
Authors: Cvetković Branislav
Published: November 2023

This paper revisits portraits of Stefan Uroš II Milutin as prince, ruler, and holy king exploring historical contexts and intended meanings within various conceptual and spatial settings. These official examples of his royal likeness come into different forms with the King shown either in prayer or frontally positioned, holding royal insignia or representation of a church, and in symbolic exchanges with saintly figures or contemporaries. Immediate political context influenced such variables of portrayals, which is why such images comprise wealthy but not fully appreciated sources that elucidate complex events from the volatile history of the medieval Balkans.
PLAŠTANICA KRALjA MILUTINA: MOTIV VASKRSENjA U ERI DINASTIJE PALEOLOGA
Authors: Beuk Bojana , Beuk Sergej
Published: November 2023

This study is dedicated to researching the significance of the Epitaphios of King Milutin as a kind of cultural and historical heritage, whose stylistic and artistic value places this artifact among the representatives of the main development of Serbian art in the 14th century. The Epitaphios of King Milutin, as a museum derivative of Serbian medieval applied art, symbolizes the canvas with which Joseph of Arimathea embalmed the body of the Savior during the funeral of Jesus Christ. The purpose of the Epitaphios is to point to the very beginning of the Christian religion, centered on the concept of Resurrection. Therefore, the empty Epitaphios in the New Testament is not only the absence of the body but also a hint of new life, implying corporality in a new and unrepeatable anthropological framework. With a specific way of making and stylistic composition, this object of sacral origin represents the embodiment of the cultural and artistic climate of the Palaeologan dynasty. One of the basic methods applied in this paper is a comparative analysis of the motifs of the Resurrection embodied in the stylistic and artistic production of Epitaphios in Serbian medieval art, as well as a review of the significance and origin of this subject. Therefore, it is provided insight into the dual development path of the Epitaphios - on the one hand, its spiritual significance with its allegorical knowledge, and on the other hand, as a material artifact of cultural-artistic and historical value.
