Full textAbstract:
Introduction: The paper considers the case of the Holy Shroud Exposition (1931) during a period of austerity, investigating accounting practices and the budget negotiation process. Aim of the work: The study seeks to illustrate the power structure underpinning budgetary negotiation processes related to the Holy Shroud Exposition. Methodological approach: The paper is based upon primary sources, considering internal accounting correspondence of the Savoy Ministry and other archival sources that have been interpreted in the light of the literature on the principal-agent theory used as framing paradigm. Main findings: The research identifies the role of accounting in managing/influencing social organisational-interactions, under specific historical conditions. In particular, the work shows the hierarchical structure of the Savoy Royal House (hereafter HSE), and verify the presence of opportunistic behaviours in the negotiation process realated to the authorisation of extraordinary expenses for the Holy Shroud Exposition. Originality: The paper permits to show the power of accounting to shape human interactions in the specific context represented by the climate of austerity, typical of interwar periods, that becomes a crucial antecedent of opportunistic behaviours.

Full textAbstract:
The fourth Ecumenical Council of Chalcedon (451 AD) sanctions, for the Holy Church very important conclusions regarding the nature of Christ. The above results do not contrast, but rather open to a natural formation of the Shroud body image. This occurs because it was affirmed in Chalcedon that Jesus Christ, the Nazarene, has two natures, one human and one divine, “inconfusedly, unchangeably, indivisibly, inseparably”, which coexist in one person (hypostasis). Consequently, the monophysitism of Eutiche and of the Egyptian, Syrian and Armenian Churches, was rejected. Now, the Resurrection of the Nazarene is a Transcendental event that, according to those like us who support the natural formation of the Shroud body image, acted only on the corpse leaving the burial linen in the Immanent, under the dominion of the natural sciences. So, the Miracle of the Resurrection shows the divine nature of Christ, while the Shroud body image formation, the human one.

Full textAbstract:
'Truth and the transunto' investigates the use of a hand-painted copy of the Holy Shroud which found its way to Bologna in the late sixteenth century. Used by the archbishop of Bologna, Alfonso Paleotti (1531-1610), this copy was the source of observations of the body of Christ, in the manner of an autopsy and is presented in Paleotti's book Esplicatione del Lenzuolo [...]. Early modern copies of the Holy Shroud are not however accurate copies, but present seemingly simplified replicas of the original. This article explores how such information, and indeed, level of trust, can come from these copies, which, to the modern eye, seem fallible. Previous studies have excused the strange appearance of these Shroud copies by considering them solely devotional instruments yet as the article shows, Paleotti's use of such an object shows that the copies might be better understood in the context of early modern natural historical studies and illustrations. The article draws on scholarship which discusses the emerging interest for visual evidence in early scientific practice and shows how certain types of images and image-making practices were able to evoke the idea of presence and clarify the indecipherable. Demonstrating that Paleotti's copy of the Holy Shroud was not just a religious tool, but also an epistemic image, this article shows how Paleotti's use of the term 'transunto' could be used as a valuable tool in gaining a more nuanced understanding of the concept 'copy' in Early Modern Europe.

The Cycle of services of Novgorod Cathedral of the Holy Wisdom included sing-ing services (ᾀσματική ἀκολουθία) after the practice of the Hagia Sophia in Constantinople. Its description is known since the 13th century from the Novgorod liturgical manuscripts. Since the end of 15th century the double- sided proskynesis icons has been an important inte-gral part of singing service in Novgorod Cathedral. The unique complex of the images of the Saviour, Mother of God, saints, and the Bible scenes was created at this time. The complicated organization composition of the Novgorod series allowed to lay one icon in the church naos at festive day or to carry out all icons with images of saints to square near Cathedral during the rites of the New Year on September 1 and on Sunday of the Last Judgement. The icons replaced one another during the Holy Week. The Shroud with the embroidery image of dead Christ was carried out from altar and put on a table in the middle of naos at Holy Saturday. The icon Resurrection (Descent into Hell) replaced the Shroud at early morning of Resurrection Sunday. It was a real “mystery of images”.

After a critical revision of the main results obtained on the hematic material of the Holy Shroud in Turin, this paper presents various news of both a macroscopic and microscopic nature. At a macroscopic level, news regarding the directions and position of blood and the probable presence of pulmonary fluid are discussed. Also, the bloodstains on the left arm are examined to try to distinguish different kinds of hematic fluid. At a microscopic level, three different types of blood are evidenced. Hypotheses have been formulated to distinguish pre-mortem and post-mortem blood and to distinguish erythrocytes on the basis of their different sizes. The presence of fibrin, earthy material, creatinine typical of a tortured person, and the stacking of erythrocytes is also discussed along with their Beta-activity and fluorescence. Finally, the physical conditions relating to Jesus are discussed from a medical point of view which could explain all the news of the hematic material taken from the HST and are consistent with the tortures of Jesus Christ described in the Holy Bible.

AbstractIntroductionMass-gathering events require varying types and amounts of medical resources to deal with patient presentations as well as careful planning for environmental health management. The Holy Shroud Exhibition was hosted in Torino, Italy, between April and May 2010. The venue was a unique mass-gathering event which lasted several weeks. It was held in a limited area in the center of the city and it was attended by a large and heterogeneous population. A dedicated Health Care Service was created for the event.MethodsThis study is a retrospective analysis of clinical presentations of patients who were managed by the Medical Services during the event. The main study outcomes included Patient Presentation Rate (PPR), type of injuries and illnesses, and the Transport to Hospital Rate (TTHR).ResultsThe PPR and TTHR were both low (0.27 and 0.039 respectively). The majority of patients presented with low severity codes and no sudden cardiac death (SCD) or cardiac arrest occurred. Cardiac and trauma emergencies were most frequent categories of presentation. A number of pediatric patients (19.37%) were treated by the event Medical Service. Approximately two million persons participated in the 40-day event.ConclusionThe experience for this 40-day event supported having an on-site, organized, dedicated Medical Service that decreased overcrowding of the local Emergency Medical System and hospitals. It is recommended that, for such events, there be recruitment of emergency physicians with experience in mass-gathering events, recruitment of pediatricians, and training for professionals during the planning process.BortolinM, UllaM, BonoA, FerreriE, TomatisM, SgambetterraS.

This paper does not discuss the authenticity or antiquity of the Holy Shroud. It addresses the problem of its historical appearance in the 1350s and its antecedents, if any, before that date. It is suggested that the object owed its creation (if a replica) or its transmission into Europe (if genuinely a relic) to the efforts of members of the Franciscan order. It speculates particularly on the role of Spirituals of that order aligned with Fra Angelo Clareno and his associates. The conclusions do not assert but suggest the thesis, and advance it as a line of inquiry meriting further pursuit.

<p><strong>Abstract.</strong> The digital acquisition of Cultural Heritage is a complex process, highly depending on the nature of the object as well as the purpose of its detection. Even if there are different survey techniques and sensors that allow the generation of realistic 3D models, defined by a good metric quality and a detail consistent with the geometric characteristics of the object, an interesting goal could be to develop a unified treatment of the methodologies. The Chapel of the Holy Shroud, with its intricate articulation, becomes the benchmark to test an integrated protocol between a terrestrial laser scanner (TLS) and a wearable mobile laser system (WMLS) based on a SLAM approach. In order to quantify the accuracy and precision of the latter solution, several forms of comparison are proposed. For the case study the ZEB-REVO, produced and marketed by GeoSLAM, is tested. Computations of cloud-to-cloud (C2C) absolute distances, comparisons of slices and extractions of planar features are performed, using stationary laser scanner (Faro Focus<sup>S</sup> S350) as a reference. Finally, the obtained results are reported, allowing us to assert that the quality of the WMLS measurements is compatible with the data provided by the manufacturer, thus making the instrumentation suitable for certain specific applications.</p>

Full textAbstract:
The Corinthian capital variant Guarini especially designed for the major order of the Chapel of the Holy Shroud in Turin serves as an example of the architect's concern with projecting meaning through architectural form. Employing construction documents from the Archivio di Stato in Turin, this study reconstructs the production history of the famous gilt-bronze "Passion capitals" of the chapel rotunda. The analysis contextualizes this unusual design, showing how Guarini responded inventively to the religious and political needs of the commission to provide an appropriately ornamented ambience for promoting the veneration of one of the central Passion relics of Christendom. Private devotional practices, Savoyard dynastic aspirations, and a moralized floral exotic all played significant roles in the creation of the new capital type as part of the larger program of the chapel. The view of Guarini that emerges from this investigation proves more tied to the prevalent expectations of seicento religiosity, patronage, and architectural culture than has often been allowed.

Full textAbstract:
Passionist religiosity was gradually established from the 12th and 13th centuries onwards, encouraged by the Franciscan ideals of imitation, meditation, and devotion to Christ, with St. Francis becoming the very image of sorrowful humanity as he received the stigmata of Christ. The medieval cult of the Passion, reiterated in the Council of Trent, continued into the Modern Age, and is preserved today in manifestations of spirituality and popular devotion, experienced through artistic images of the Passion of Christ, as well as the veneration of relics of Vera Cruz, the shroud, among others. The liturgy and devotion have used and still use these images in religious solemnities, of which the Holy Week ceremonies stand out, as well as in theatrical performances in which the image serves as a vehicle mediating between two worlds, the earthly and the celestial, following the itineraries of the Stations of the Cross which, from the 15th century onwards, allow us to relive the final stages of Christ’s earthly life in the Holy Land.

In addition, the author compares the facts of the appearance of the canonical image of Jesus Christ on icons, mosaics and frescoes, the Holy Shroud, and coins of ancient states. The author justifies the dating of the events of the New Testament to the beginning of the XI century on the basis of established facts, and not the generally accepted canons of faith.

Full textAbstract:
This article seeks to highlight the relevance of Marie-José Mondzain's trailblazing writings on Byzantine image theory and its modern legacy, with particular reference to Image, icône, économie (Image, Icon, Economy, 1996) and Homo spectator (2007), to the revived debate about belief in cinema. Like André Bazin's and Christian Metz's classical accounts of this subject, Xavier Giannoli's film L'Apparition (The Apparition; 2018) grants a privileged role to a holy shroud and other visual fetishes; it also deals, like Mondzain, with their relations to invisible authority. I argue that Mondzain's writings and Giannoli's film enrich our appreciation of cinema's affinity with belief by staging complementary critiques of the empowerment of institutions by images.

Full textAbstract:
In modern practices of Russian Orthodoxy, the feast of the Virgin Mary Dormition is solemnized with great splendor. During these celebrations in large and small religious centers, a liturgical image, in the Russian Orthodox Church called “The Theotokos Holy Shroud”, becomes the central temple image. This article, for the first time, makes an attempt to track down a continuity in the Dormition Shroud images creation — from royal craftwork rooms of medieval Russia to modern workshops. Learning on previous masterpieces, present-day apprentices contribute to preservation and development of the unique traditions of national culture. The article introduces into scientific circulation a number of rare artifacts that become a subject of research for the first time. The study provides facts refuting the nowadays-widespread opinions that, in the alleged absence of material evidence (preserved monuments) of an earlier time, the period in which these images originated dates back to the late 19th century. This determines the relevance of the study. The author comes to the conclusion that, however brief and undescriptive the data recorded in documentary sources are, they make it clear that these relics already existed in the late Middle Ages, though questions of authorship and artistic value of the works still remain to be answered. This analysis becomes possible through studying the Synodal era images discovered in vestiaries of churches in the Moscow region, as well as those reported in some historical descriptions. Modern masters recreate works of high artistic level, applying a combination of the ancient heritage and the modern variety of materials and innovative technologies. The data presented in the article contribute to further studying of the issues embracing emergence and spread of the liturgical images of the Theotokos Shroud in the practices of Russian Orthodoxy. It is also important to trace back the historical background of those selected artifacts first mentioned in this paper.

Religions have always played a significant role in the formation of the statehood and development of such powerful states as the Byzantine Empire, the Holy Roman Empire, the Kievan Rus, or the Empire of Charlemagne. Peculiarities of the national culture are dictated by its faith. This is due to the fact that folk traditions, mentality, political structure, peculiarities of the historical trajectory of each nation including the religious development, have a tremendous influence on the religious aspects of nations and states. Religious attitudes, religious morality, practice of ceremonies, and church institutions deeply penetrate into everyday lives of people and countries in particular, largely determine their local originality as well as national and cultural identity. In general, the influence of religious-confessional factors is felt at all levels of organization of society’s life. The diversity of its manifestations is unlimited, and basically, it is not the impact on the life, but the life itself. This thesis should always be remembered either when illuminating the tourist resources of the country or the conditions of organization of the tourism business. The article is referred to the religious tourism in Italy – the country on the territory of which Christianity (Holy Roman Empire) arose. The article concideres such religious objects of Rome as Vatican, the Basilica of St. Peter, the area around the Capitol, religious practices of the city of Loreto called the Holy House, as well as the worship of sacred Turin Shroud.

Full textAbstract:
Guillaume Du Fay composed his Missa Se la face ay pale, based on his ballade of the same name, during his final sojourn at the Court of Savoy in Chambééry from 1452 to 1458. It has been suggested that the piece celebrated the consummation of the wedding of Amadeus of Savoy and Yolande de France in 1452, but the basis for assigning it to this occasion ——that a song about a man whose "face is pale" for "reason of love" might refer to a bridegroom——is weak. A fresh look at this seminal composition points to a different rationale, one stemming from examination of the affective theology of the fifteenth century that influenced art in all its forms. Late medieval Passion treatises, dialogues, sermons, lives of Christ, along with related paintings often depict Christ as the man with the pale face. In his final hours on the Cross, Christ's physical aspect is described as "pale" or "pallid." The "reason" for his disfigurement is his "great love" for mankind. In sacred dialogues between Christ and the female soul ("anima"), the Man of Sorrows conveys his love and encourages her to "see" or "behold" his wounds and study his "bitter" passion. The language of Du Fay's ballade is strikingly similar: "If the face is pale / The cause is love, / That is the main cause; / And so bitter to me / Is love, that in the sea / Would I like to see myself." What prompted Du Fay to use this song in his Missa Se la face ay pale? This article proposes that an important Christological relic, the Holy Shroud, acquired by Du Fay's patron Duke Louis of Savoy in 1453 (and not moved from Chambééry to its present location in Turin until 1578), lies at the heart of the work, and that the composer incorporated theological symbols in the Mass to associate it with this sacred remnant. Recognition of early Christ-Masses such as the Missa Se la face ay pale helps to redefine the word "devotional" and illuminates the beginnings of Mass composition with secular tunes and of emotional expression in sacred music.

Introduction. The meaning of the Holy Saturday is a transition from Passion week to the Easter, from the greatest grief to jubilation, from death to life. It focuses different ontological extremities in a single point: death of the Immortal and resurrection of mortal body. This engenders maximal concentration of liturgical events, exceptional saturation of the services, revealing ample hymnographic material, diversity of stylistics, ways of incarnating of different senses, approaches to the events happening. One of the most interesting chants of the Passion Cycle is “Ne riday Mene, Mati” (“Do not mourn Me, Mother”), with its wonderful poetics, profound images and lapidary structure. Vividness and theological deepness of this chant provide inexhaustible material for research. Theoretical Background. In modern theological literature “Ne riday Mene, Mati” is mention in the context of special traits of the Holy Saturday services (I. Karabinova (1910), A. Kashkin (2010), M. Krasovitskaya (2014), G. Shimanskiy (2002) etc. It was characterised in more details in the researches on the Byzantine singers, among them the most important are works by archbishop Filaret (Gumilevskiy) and nun Ignatia (Puzik). Describing the personality and works of St. Kosma Mayumski, archbishop Filaret notes concentration of his style. Nun Ignatia studies images of this author’s works, their foundation in creed, links with dogmas of the Church; stresses features of poetics as well as dissects canons for Epiphany and Christmas. She pays special attention to the canons dedicated to Holy Mother, and she mentions “Ne riday Mene, Mati” as one of the most touching work by St. Kosma. Unfortunately, detailed analysis doesn’t follow this statement, that makes given paper relevant. Objective of this article is to study location of chant “Ne riday Mene, Mati” in service, specifics of its content, influence on later hymnography and iconography. Methods. Given that this research addresses theology, corresponding terminological system has been used, including special concepts as well as Church Slavonic words and expressions. Results. “Ne riday Mene, Mati” is an irmos of the ninth chant of the canon sung at the morning service on the Holy Saturday and devoted to suffering and death of Jesus Christ, interpreted as a culmination of the salvation of humanity. It has a distinctive feature of personal appeal of the Son to the Mother, answering her grief and closing a dialogical form in a spacetime of the whole service and Passion week, defining specifics of the poetics of its services. Several levels of content can be defined in a chant: 1) personal, describing relations between the Mother and the Son; 2) soteriological, revealing Lord’s plan of the salvation of humanity; 3) dogmatic, presenting dogmas of Christ and Holy Mother; 4) celebratory, establishing praise of the Mother of God. The structure of the irmos is defined by a triad thesis – antithesis – synthesis. Thesis is imperative expression (addressing “Ne riday Mene, Mati”), antithesis is justification of this reaction (“zrjashhi vo grobe, Ego zhe rodila esi Syna”). Not only does the synthesis resolve appearing contradiction, but also transfers the relations between the Son and the Mother into sphere of God-man relations. In this context the initial imperative can be understood as a demand for silence and tranquillity of soul, for absolute concentration in the situation of the contact with Godly essence. The same demand is situated in one of the crucial moments of liturgy of the Holy Saturday, in the time of The Great Entrance: “Da molchit vsjakaja plot chelovecha”. For the second time “Ne riday Mene, Mati” is sung in the final part of Eucharistic canon of the liturgy. In this context it brings out completely different facet, reincarnation of the God in a human through Resurrection. Thus, due to changes of context and place in the service, “Ne riday Mene, Mati” undergoes modulation of meaning. For the third and last time, “Ne riday…” appears in the Eastern Midnight office, that is a threshold between the Holy Saturday and The Easter, accompanying appearance of the shroud with the image of Jesus Christ. Thus, “Ne riday…” ends all the Passion cycle of the service. The profoundness of the images and dogmas as well as structure exceptionality of “Ne riday Mene, Mati” is reflected in later hymnography. Irmoses of the canons sung on Eves of Epiphany and Christmas are constituted in a way, similar to irmoses of the Holy Saturday. They preserve images, poetic devices, genre traits (irmos of the canon), glas (voice), usage of acrostic, thesis – antithesis – synthesis principle of composition. Besides for hymnography, “Ne riday Mene, Mati” influenced iconography of the stated image. All the most vital aspects of it have found their incarnation in iconography: Birth from the Virgin (iconography “Eleusa”), Crucifixion (the Cross, pierced rib), death and burial (crossed hands, closed eyes of Christ, stone tomb), Resurrection, appeal to the Mother (leaning of the Saviour’s head) as a sign of a dialogue; and every aspect from the abovementioned is a separate edge of multidimensional meaning of the Holy Saturday. Conclusions. Through analysis specifics of content and composition of “Ne riday Mene, Mati” is revealed. Dialogue is defined as a crucial principle, causing peculiar poetics of this chant and all the services of the Holy Saturday. Role of silence as one of the factors of the reception of the content is stated. Logical principle of structure thesis – antithesis – synthesis is brought out. Connections are drawn between this chant and its “podobnas” in texts of Menaion and Octoechos. Perspective of the further research lies in studying of dialogue in service of the Holy Saturday on micro- and macrolevels. Specifics of influence of chants on the iconography seems to be worthy of attention.

Flow over bluff bodies produces vortex shedding in their wake regions, leading to structural failure from the flow-induced forces. In this study, a passive flow control method was explored to suppress the vortex shedding from a circular cylinder that causes many problems in engineering applications. Perforated shrouds were used to control the vortex shedding of a circular cylinder at Reynolds number, Re = 200. The shrouds were of non-uniform and uniform holes with 67% porosity. The spacing gap ratio between the shroud and the cylinder was set at 1.2, 1.5, 2, and 2.2. The analysis was conducted using ANSYS Fluent using a viscous laminar model. The outcomes of the simulation of the base case were validated with existing studies. The drag coefficient, Cd, lift coefficient, Cl and the Strouhal number, St, as well as vorticity contours, velocity contours, and pressure contours were examined. Vortex shedding behind the shrouded cylinders was observed to be suppressed and delayed farther downstream with increasing gap ratio. The effect was significant for spacing ratio greater than 2.0. The effect of hole types: uniform and non-uniform holes, was also effective at these spacing ratios for the chosen Reynolds number of 200. Specifically, a spacing ratio of 1.2 enhanced further the vortex intensity and should be avoided.

Full textAbstract:
The flow field was measured near the inlet and the outlet of an axial flow inducer with shrouded and unshrouded configurations combined with a centrifugal pump. Investigations were conducted using a five-hole probe for several flow rates. The shroud induces a counterrotating flow at the inlet and a blockage effect at the outlet in the region of the tip and for all flow rates. The radial distribution of losses keeps the same shape in both configurations, however, the loss level is higher with the shroud, giving a lower efficiency for the combined inducer-impeller configuration. Effects of shrouded inducer on part load instability are not clear and deserve more research, which is in progress.

Saint Canute the King’s Eagle Cloth in Odense CathedralA new interpretation The eagle silk cloth in Odense Cathedral (Fig. 1) is believed to have been part of the contents of the shrine of Saint Canute (King Canute the Holy); it was perhaps a cape used as a shroud. Today it measures 110 by 133 cm, but originally it was larger, at least 130 by 195 cm. The purple fabric with its blue-black eagle pattern and decoration is generally regarded as a “pannus imperialis ad aquilas magnas” – a term known from medieval texts. The style of its decorative motifs dates it to the 11th or 12th century. Otto von Falke regarded the Odense cloth and related fabrics as the products of the Byzantine state workshop. Agnes Geijer, on the other hand, assumed that the Odense specimen was made by Islamic weavers in Southern Italy or Sicily and that it had formed part of the gifts which Canute’s widow, who had later married Duke Roger of Apulia, sent to the saint’s shrine.Underneath the eagle pattern on the cloth there seems to be an inscription (Fig. 2). Although only a few of the letters are legible the classical philologist Carsten Høeg considered them to be based on Greek letter-forms. It is in fact possible to distinguish at least five, and in addition, there are some possible ligatures of two or three letters (Fig. 3). A comparison between these vestiges and well-known Byzantine textile inscriptions leads to the impression that the last word could have been DESPOTOU, and that several of the preceding signs may be part of the word PHILOCHRISTOU. If so, we have an official dating, and even the name of the emperor in question. Among the rulers in the 11th and the 12th centuries, only five had a name short enough to fit into this context, and if we are right in distinguishing an alpha or a lambda in the beginning, this would exclude all but Alexios. Consequently, we will venture to make a hypothetic reconstruction with this name based on the existing remains (Fig. 4).The style of the fabric makes it most unlikely that anyone else but Alexios I (1081-1118) could come into question. It was he, who – probably in 1103 – received Saint Canute’s brother, King Eric the Good (Erik Ejegod), who died that very same year in Cyprus on his way to the Holy Land. In Eiriksdrapa, the memorial poem written in honour of this king by the contemporary Icelandic bard, Markus Skeggjason, it is explicitly stated that among other rich gifts, Eric was presented with an imperial garment: “allvalds skruði”, i.e. “the emperor’s shroud”.One of the present authors has drawn attention to the possibility that the bluish dark colour of the eagles indicates that the fabric was intended for a “sebastokrator,” a brother or son of the emperor or someone else very close to him. The colours, the eagles, and the size of the cloth would actually be appropriate for the type of garment called a “paludamentum”, a purple officer’s cloak worn by the emperor and other highly prominent persons (Figs. 5-6). Some of the leaders of the First Crusade were honoured by being elevated to the status of adopted sons of the emperor, and Krijnie Ciggaar has wondered whether the same could have happened to Eric. If this was the case, then it seems that it was Eric’s imperial silk cloth that was transferred to Odense as a tribute to his more distinguished brother, the martyr saint.Recently, it has been stated that the red colour of the Odense cloth is not genuine purple. However, the loss of most of Anatolia and Lebanon made it difficult for Byzantine workers to obtain the right colour components. Genuine murex-purple was in fact used in Constantinople until the thirteenth century, but this top-quality purple was reserved for the emperor alone. This explains why an inferior dye quality was used for the Odense cloth, which was made for a person with the rank of a sebastokrator.P.J.

Full textAbstract:
In the churches of St. Dimitrije in Dobrotin near Lipljan and St. Nicholas in Kosovska Kamenica, there are iconostases whose icons were painted by the painter Hajji Kostadin Krstev from Veles in 1862. He worked on the territory of the Diocese of Raška and Prizren in the first half of the seventh decade of the 19th century, when he painted the church of the Devič monastery, created the iconostasis in the church of the Holy Archangel Gabriel in Veliko Ropotovo near Gnjilane, the iconostasis and wall painting in Dobrotin, as well as all icons, apart from those of the Great feasts, for the iconostasis in the church of Saint Nicholas in Kosovska Kamenica. Also, with the painter Ignjat from Veles, who helped him in painting of the church in Dobrotin, he created painted decoration for the throne of the miracle-working icon of Peć. The iconostases in Dobrotin and Kosovska Kamenica, as well as the one in Veliko Ropotovo, are modest three-zone wooden constructions. They were made according to the Balkan cultural model and zographic pictorial poetics, and they differ slightly from each other in terms of dimensions and the number of icons. Both iconostases have modest or no relief decoration. The iconostasis in the church of St. Demetrius in Dobrotin has only two throne icons and high parapets under them, the imperial doors that are not even painted, and north and south doors that are painted. Above the throne icons there are two rows of icons, arbitrarily arranged, with figures of saints and representations of Great feasts. At the very top of the iconostasis, there is a monumental cross with the crucifixion of Christ. On several icons in the higher zones, there were inscriptions, but only the one on the icon of the Shroud of the Holy Virgin is preserved and states that it was a gift from Milovan Rašić. The names of other donors are not legible. The iconostasis represents a unique whole with the wall painting. The iconostasis in the church of St. Nicholas in Kosovska Kamenica has a somewhat different appearance, but it was made and painted according to the same pictorial and dogmatic principles. It has five throne icons, the imperial and northern doors. In the second zone, there is a row of icons with the figures of the apostles, and above them a row of icons of the Great feasts, which are the work of Vasilije Djinoski. At the top, there is a painted Crucifixion of the Christ, set on the relief dragons. This paper presents in detail the iconography of all the icons, which were simultaneously compared to each other, as well as to the icons painted a year earlier in Veliko Ropotovo.

Full textAbstract:
A low turbulence Reynolds number k-ε model has been used in conjunction with an elliptic flow calculation procedure to obtain finite-difference solutions for radial outflow in the cavity formed between two plane corotating disks and an outer peripheral shroud. Air enters the cavity axially through a central hole in one of the disks and is assumed to leave via a uniform sink layer adjacent to the shroud. The main emphasis of the paper is the extension of the solution procedure to cover high rotational speeds, with rotational Reynolds numbers up to 107. As a necessary prerequisite to this exercise, the turbulence model is validated by its good predictive accuracy of existing experimental data up to a maximum rotational Reynolds number of 1.1 × 106.

Full textAbstract:
Flow visualization and heat transfer measurements have been made in the cavity between two corotating discs. The discs were 762 mm in diameter and could be rotated up to 2000 rpm. Air, at flow rates up to 0.1 kg/s, entered the cavity through either a central hole 76 mm in diameter or a porous inner shroud 380 mm in diameter; in both cases, the air left via holes in an outer shroud attached to the periphery of the discs. Flow visualization confirmed that Ekman-layer flow could occur: A source region, Ekman layers, sink layers, and interior core were observed. A simple theoretical model provided estimates of the size of the source region that were in satisfactory agreement with the observations. At sufficiently high rotational speeds, where Ekman layers form over much of the surface of each disc, measured Nusselt numbers were in reasonable agreement with values computed from the momentum-and energy-integral equations.

Full textAbstract:
This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 201127, “An Experimental Investigation of Highly Deviated Shroud-Type Downhole Separators,” by Jorge Lopez, Eduardo Pereyra, SPE, and Cem Sarica, SPE, The University of Tulsa, prepared for the 2020 SPE Virtual Artificial Lift Conference and Exhibition—Americas, 10–12 November. The paper has not been peer reviewed. An experimental study of a shroud-type downhole separator for a pumped horizontal or deviated well is presented in this study. The separator is located at high deviation angles (i.e., 45° to 80° from vertical). The effects of the upstream gas and liquid flow rates are evaluated in the performance of the downhole separator. The findings complement previous studies on shroud-type downhole separators and demonstrate the operational capability of downhole separators under a range of conditions. Introduction Even though free gas and gas interference at the pump intake is a well-known problem, a limited understanding exists of the mechanisms that result in free gas in the pump. The lack of knowledge may lead to installation of ineffective downhole separator pump assemblies that, in some cases, may be detrimental to pumping-system performance. Among downhole-separator types, gravity-driven separators take advantage of the density difference between the gas and liquid to achieve separation. The shroud-type separator is an uncomplicated yet robust design and the most well-known and applied in the field. Current horizontal wells present challenging operational problems to down-hole separators and artificial-lift systems. The correct design of the downhole separator must consider proper handling of new challenges. A limited number of studies exist on the current challenges of downhole separators. A few of these studies considered the flow upstream of the separator as a variable, a limited amount studied deviated cases, and none focused on high deviation angles. Experimental Setup The complete paper details the experimental facility and instrumentation. The Tulsa University Horizontal Wells Artificial Lift Projects’ low-pressure outdoor downhole separator facility was used in this study. Four gas and eight liquid flow rates were used in the experimental matrix. The deviations tested were from 45° to 80°. Some of the tests at higher liquid flow rates were not completed because, as the deviation increases, the higher liquid flow rate causes the casing to overflow, making completion of these experiments impossible. The considered gas and liquid flow rates allow the analysis of gas/liquid ratios varying from 5 to 1,800 scf/bbl. Experimental Results The authors found that separation efficiency depends strongly on the liquid flow rate and deviation angle. At 45° and 60°, the separator seemed to perform efficiently for all tested conditions. At higher liquid flow rates, the separation efficiency showed a slight decrease, but, because of facility limitations, not enough evidence existed to confirm the tendency. Therefore, an additional two tests at 45° were performed to validate this trend. The tested conditions were 1,360 B/D with 7 Mscf/D and 11.28 Mscf/D. The two additional tests at 45° confirmed that efficiency decreases as liquid production increases. The authors observed two regions of operations of the separator for vertical cases and different deviation angles (the highest deviation tested was 45°). For their conditions, the separator performed in a high-efficiency region (efficiency between 80 and 100%) for low liquid flow rates. As the liquid production increased, the separator efficiency decreased. The authors denote this area of operation as a disrupted-efficiency region. The authors did not observe the separator to fail at 45° despite testing the separator at higher liquid flow rates.

Full textAbstract:
The flow pattern is vital for the metallurgical performance of continuous casting tundishes. The purpose of this study was to design and optimize the flow characteristics inside a four-strand tundish. Numerical simulations and water model experiments were validated and utilized to investigate the flow behavior. The effect of different flow rates in the original tundish was evaluated; two modified retaining walls and a new ladle shroud were designed for optimization. The molten steel inside the original tundish tends to be more active as the flow rate increases from 3.8 L/min to 6.2 L/min, which results in a reduction in dead volume from 36.47% to 17.59% and better consistency between different outlets. The dead volume and outlet consistency inside the tundish are improved significantly when the modified walls are applied. The proper design of the diversion hole further enhances the plug volume from 6.39% to 13.44% of the tundish by forming an upstream circular flow in the casting zone. In addition, the new trumpet ladle shroud demonstrates an advantage in increasing the response time from 152.5 s to 167.5 s and alleviating the turbulence in the pouring zone, which is beneficial for clean steel production.

Abstract The personal library of Jacques Derrida, acquired by Princeton University in 2015, includes a richly annotated copy of George Eliot’s The Lifted Veil. Derrida’s marginal markings reveal preoccupations shared between Eliot’s narrator, Latimer, and the persona of his 2001 book Veils, specifically the allure of the unknown, the city of Prague as a volatile setting, certain versions of the veil they hold in common (in particular veil as shroud), and the inclination they share toward deconstructing binary oppositions (in particular life and death). Such connections justify the continued interest in Eliot by deconstructionists in this century, as well as K. M. Newton’s description of George Eliot as “proto-Derridean.”

Full textAbstract:
This paper reports on the re-engineering of standard five-strand tundish designs into a five-strand asymmetric tundish, which resulted in a non-uniform rate and bias for each strand. We sought to improve the casting conditions by optimizing the liquid steel flow-field in the tundish. Both a water modelling experiment and a numerical simulation were performed to analyze the flow-field according to various diversion hole diameters and injection angles. The results showed that the average residence time decreased as the diameter of the diversion holes increased. As the injection angle was increased, the average residence time initially decreased and then increased. The liquid steel from the ladle shroud rapidly extended to the #2 and #3 strands in the original tundish, which reduced the likelihood of inclusion collision and coalescence.

Full textAbstract:
Numerical simulations of a canned motor pump at partial load condition have been conducted for studying the strong rotor–stator interaction. SST [Formula: see text] turbulence model with wall function was adopted for solving three-dimensional (3D) unsteady Reynolds-averaged Naiver–Stokes (URANS) equations. The inner flow field for four typical rotor positions, where the head changes significantly, was explored. It has been shown that when blade approached tongue region, the radial velocity decreased where the pressure at suction side was bigger than pressure side. As a result, a negative work was exerted on the fluid which led to minimum work done by the impeller. At this condition, maximum work was resulted in due to the upstream blade. The fluid from balance hole affected the main flow near hub region which caused a vortex near channel pressure side. Due to impeller channel rotation through tongue, the vortex was enlarged which contributed separation flow at impeller inlet region. The separated flow caused pressure reduction in the channel. Static pressure at impeller outlet near shroud side was always greater than at near hub side which resulted in negative radial velocity at impeller outlet near shroud side. Due to the blade accession to the tongue, the static pressure at impeller channel increased meanwhile the area characterized by negative radial velocity enlarged.

Full textAbstract:
This paper addresses the use of 5-hole probes in the testing of industrial centrifugal compressors. The 5-hole probes utilized for this work are of the conical-tip type and were used in a non-nulling configuration (i.e., the probes do not need to be rotated or moved in any way during the tests). These 5-hole probes proved to be fairly robust, making them practical for a nonlaboratory setting such as an industrial multistage compressor test stand. A discussion of 5-hole probes and how they function is provided, including an overview of the mathematical formulations and calibrations required to translate the pressure data gathered from the 5 holes into static and total pressures, velocities and flow angles. A method to transform these variables from a probe-based coordinate system to a machine-based coordinate system is also presented and schematics of this process are provided to aid the reader’s understanding. The testing performed on a prototype multistage centrifugal compressor using 5-hole probes is also discussed, showing that the probes provided valuable insight into the flowfield exiting the impellers and at the return bend. The hub-to-shroud velocity profile exiting an impeller was found to be more skewed than expected and was contributing to poor performance in the downstream stationary components. The measured flowfield from one of the tests is also compared against 3-D CFD results and comments are offered regarding the agreement between the analytical and measured results. Advantages and disadvantages of 5-hole probes as compared to more conventional instrumentation are presented. Finally, conclusions are drawn regarding the value of 5-hole probe data in the development and/or troubleshooting of high performance turbomachinery and in the validation/calibration of design and analysis tools.

Full textAbstract:
This article focuses on the impeller construction, non contact driving method and performance of a newly developed shaftless floating pump with centrifugal impeller. The drive principle of the floating impeller pump used the magnet induction method similar to the levitation theory of the linear motor. In order to reduce the axial thrust by the pressure different between shroud and disk side, the balance hole and the aileron blade were installed in the floating impeller. Considering the above effect, floating of an impeller in a pump was realized. Moreover, the performance curves of a developed pump are in agreement with a general centrifugal pump, and the dimensionless characteristic curve also agrees under the different rotational speed due to no mechanical friction of the rotational part. Therefore, utility of a non contacting magnetic-drive style pump with the floating impeller was made clear.

Filipinos consider Holy Week as the holiest of days of Lent and Easter. During this time, the country is shrouded with centuries-old rituals and practices that persist in contemporary times. Using the framework of gender performativity, this study examines three forms of pamamanata (devotion): pagsasanto (taking care of a religious image), penitensya (penance), and salubong (Easter procession). The aim is to identify pamamanata practices that align with the feminine, masculine, gay, and those bordering between masculine and feminine tropes. The study maximized data from the author’s fieldwork and ethnographic materials written by academics. This study found that the three pamamanata traditions are gendered practices and that these are affected by the agencies of the family, community, and religion.

Abstract Plots were located at the Colorado State University Bay Farm in Fort Collins in an established planting of honeysuckle bushes, 2-3 ft high. Individual plots consisted of single shrubs, and plot design involved a randomized complete block with 5 replications. Prior to treatment, 3 aphid-infested terminals on each shrub were marked and all aphids were counted. Subsequent aphid counts involved the same terminals. Insecticide applications were made 18 May to infested shrubs that already showed leaf-curling injury. Orthene 75 S was sprayed to run-off Dimethoate 400 and Metasystox-R 2 were applied as soil injections using a Kioritz soil injector applying 1.25 fl oz/injection hole. Injections were made at a rate of 1 hole per half-inch of diameter at soil level, a total of 3-4 insertions/shrub, depending on size. Dimethoate 400 was applied as a 1:3 dilution with water; Metasystox-R 2 was applied as a 1:1 dilution.

The yaupon psyllid, Gyropsylla ilecis (Ashmead), is a native insect of the family Psyllidae, order Hemiptera (Figure 1). The insect is inconspicuous during most of the year, but the leaf galls it produces in spring are more easily observed. Nymphs feed on the new growth of yaupon holly, Ilex vomitoria, causing leaves to deform into a protective gall. The yaupon holly, native to the southeastern United States, is used as an ornamental tree or shrub and has also been used for centuries to produce a caffeinated, tea-like beverage. The yaupon psyllid is considered a minor aesthetic pest due to the unsightly presence of galls and some stunting of twigs. However, yaupon holly is rarely severely damaged by this insect.

Full textAbstract:
Many funeral guidelines and regulations were imposed during the COVID-19 restriction movement to control the risk of Corona spreading, such as maintaining social distance and indoor and outdoor safe gatherings. Due to the high risk of contagion, some religious rites were avoided, like the gathering of many comforters, taking the farewell look at the deceased, and almost cancelling the decrees of religious burial and grief, which are spiritual remedies for those who lost their loved ones. Since both Judaism and Islam forbid cremation, the burial rites should be strictly monitored, and the decision to hold a modified mourning tribute for the deceased must be taken cautiously and in cooperation with the competent medical authority. But how does the new funeral regulation coincide with religious values? And how could Jewish and Islamic traditions about washing the infected deceased’s body, burial shroud, coffin, cemetery, initial mourning period, and other customs be preventive healthcare instructions? This article is attempting to answer these questions in light of Biblical and Quranic teachings.

AbstractBackground:An in-house self-held respiration monitoring device (SHRMD) was developed for providing deep inspiration breath hold (DIBH) radiotherapy. The use of SHRMD is evaluated in terms of reproducibility, stability and heart dose reduction.Methods and materials:Sixteen patients receiving radiotherapy of left breast cancer were planned for treatment with both a free breathing (FB) scan and a DIBH scan. Both FB and DIBH plans were generated for comparison of the heart, left anterior descending (LAD) artery and lung dose. All patients received their treatments with DIBH using SHRMD. Megavoltage cine images were acquired during treatments for evaluating the reproducibility and stability of treatment position using SHRMD.Results:Compared with FB plans, the maximum dose to the heart by DIBH technique with SHRMD was reduced by 29·9 ± 15·6%; and the maximum dose of the LAD artery was reduced by 41·6 ± 18·3%. The inter-fractional overall mean error was 0·01 cm and the intra-fractional overall mean error was 0·04 cm.Conclusion:This study demonstrated the potential benefits of using the SHRMD for DIBH to reduce the heart and LAD dose. The patients were able to perform stable and reproducible DIBHs.

Full textAbstract:
Balancing holes in single-suction centrifugal pumps are generally applied to attenuate the axial thrust caused by a pressure difference between the front side of a shroud and the rear side of a hub of an impeller. The magnetic drive pump, the subject of this study, has a leak-free airtight structure and an integrated structure of the impeller and inner magnet. To prevent the performance degradation of the magnetic drive caused by heat during operation, complex cooling flow paths connected to balancing holes have been designed so that a sufficient amount of coolant would flow around the magnetic drive. Due to this spatial characteristic, when balancing holes are applied to a magnetic drive pump, the balancing hole flow path becomes very long compared to that of balancing holes applied to conventional pumps. When the balancing hole flow path is long, the flow path loss increases, which in turn increases the adverse effect of balancing holes on the pump performance. Therefore, the design of highly efficient balancing holes to which a sufficient amount of coolant can be supplied is critical in a magnetic drive pump. To this end, two types of balancing holes were investigated in this study. First, balancing holes are drilled in the impeller that rotates during operation. Second, balancing holes are drilled in the inner shaft installed to maintain the centre of rotation of the impeller during pump operation. The results confirmed the flow characteristics of the two types of balancing holes and verified the effect of each balancing hole on the pump performance. Finally, this study found that drilling balancing holes in the shaft were appropriate for the magnetic drive pump, and this type can maintain relatively high efficiency and supply a sufficient amount of coolant to maintain the efficiency of the magnetic drive.
