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

Among the ten celebrations of the Mass of St Basil in the Orthodox Church during the year are the conclusions to the three Vesper services immediately before the three major feasts of Christmas, Epiphany and Easter. Two of these Vesper services – those for Christmas Eve and the Eve of Epiphany – are of particular musical interest since they contain psalms with troparia or antiphons, for both of which the entire music can be transcribed from thirteenth-century manuscripts, so that these two services can be celebrated with what are, almost certainly, the oldest known complete examples of Byzanti

Six months ago, these were hypothetical questions reserved for academics, for sacramental and liturgical theologians. In March, these became the questions of every Catholic who could no longer inhabit the pews of their church.

Sirri marriage is a growing phenomenon in society. The apparently large number of sirri marriages is due to widespread reporting by mass media, printed and electronic. As a part of religious teachings, marriage is a holy institution to humanize mankind. The purpose of marriage cannot be achieved if there is an effort to subvert its core values. One of the things which may reduce the essence of marriage is sirri marriage, as it is not recorded by the Office of Religious Affair and thus does not carry the same legal force as official marriages.

As the cities, destinations, and tourism become smarter every day, religious tourism must get its share from emerging technological benefits. Every year, millions visit various holy places. A significant amount of data can be collected from millions of pilgrims. If this data are analyzed accurately, destination management and experience enhancement can be performed much easier than today. The aim of this study is to discuss the motivation of religious tourists, and how to implement smart destination principles in religious sites.

Abstract:
This chapter analyses what happens once regeneration moves beyond the early consultation stage. In stark contrast to the official regeneration rationale – creating better places – residents experience physical, social, symbolic and psychosocial degeneration. Physical degeneration entails managed decline – worse maintenance, repairs and cleaning services, while about-to-be demolished estates miss out on Decent Homes Programme funding (Chapter 2). Social degeneration occurs as familiar neighbours leave and are replaced by a shifting gallery of squatters, temporary tenants and property guardians. Estates consequently become more socially anomic places as local social capital declines and anti-social behaviour increases. The half-empty estates, pock-marked by boarded-up properties, suffer symbolic degeneration as they perversely become attractive locations for mass media urban dystopian programmes and films, heightening territorial stigmatisation. Psychosocial degeneration occurs as the remaining residents suffer from enormous psychological strain – including the noise and dust stresses of living on a building site, the depressive loss of familiar faces, and anxiety regarding displacement. The endless nature of degeneration/regeneration propels residents into a limbo-land of lives put on hold. These degeneration strands close the ontological gap between the ‘sink estate’ place myth and residents’ lived experiences. As this gap closes, the stage is set for residents’ displacement (Chapter 10).

Abstract:
Much ink has already been spilt on the unprecedented terrorist attack in Paris on November 13, 2015 in an atmosphere of endless despair. Many characterize it as the “new 9-11”. Nevertheless, they tend to defy the significant fact that that attack was launched by an acknowledged organization, Al-Qaeda, acting as a frontispiece of the Afghan state. In the present case study, the current threat is of a much larger extent and ambit, gradually conquering the globe. What one needs to conceive is that ISIS enjoys no single and specific nationality- on the contrary, it operates as an amorphous mass, a totality achieved as a result of illegal forms of collaboration and interstate crime in countless regions of the world, though serving a common purpose: the violation of security, democracy and freedom of expression. The ultimate goal of the organization is the breakdown of democratic regimes and the emergence of the Caliphate as a global superpower that will handle telecommunications, (inter) governmental, (inter) state security systems, and so on. One thing is for sure: Islam serves as the pretext for these modern bloody crusades. No religion that respects itself preaches and initiates a “holy war”; a war that is being constantly heretically interpreted- to say the least. Global co-operations frequently alter, as the international components are defined by ephemeral alliances, perhaps with classic conflicting interests, such as the US-Russia common goal opponent against ISIS. Parallel to that, other fronts hover vis-à-vis the question of military intervention of France and USA-UK in the disputed area of Raqqa, the struggle between Turkey and Russia around the management of natural resources not only on their behalf, but also in terms of ISIS, the implementation of geopolitical strategies over the area along with the future of millions of Syrians, who were accounted for either as refugees in neighboring countries, such as Lebanon, or Internally Displaced Peoples (IDPs). The recent EU-Turkey Ankara Summit on refugees ignited hot debate over the way in which the Schengen area should be further fostered via the creation of the so-called “refugee hot-spots” within the Turkish territory.

Abstract:
Development of liturgical space in Franciscan churches between 13thand 18th centuries The aim of this writing is to show changes which took place in sacral space of Fran-ciscan temples. At first Friars Minor Conventual were occupying small, abandoned churches. There they found their space for prayer. However, the first generation of Marcin Drąg OFMConv98 the followers of St. Francis did not possess their own sacral area. Instead, they were only its users.Letters of the order’s founder are clearly defining sensitivity connected with cult which all members of the order should possess. Therefore emerges a need of sacral space’s arrangement just in the first decades of the order. Thanks to papal privileges and a demand for ceremonial celebration of liturgy, Franciscan churches are equipped with choirs, lecterns and all paraments needed. This fact is affirmed by Ordinationes(the Franciscan liturgical statutes).The 1260 Narbonne constitutions defined a plan for sacral space of Franciscan churches. It was based on order’s spirituality. The crucified Saviour is put in the middle of this plan. His sacrifice is being re-lived in the mystery of the Holly Mass. Virgin Mary and Saint John the Apostle are participating in this sacrifice as represent-atives of the Church, while Saint Francis and Saint Anthony are representing people redempted with Christ’s blood. By following Jesus, they have received a prize of His eternal companion in heavenly glory.Simultaneously with arrangement of God’s service in conventual churches, friars are becoming more open to fraternity, which determine later arrangements in space of Franciscan churches. Many churches has become places of relics worship and important shrines, with Assisi and Padua among others. Spirituality of the Order and devotion of people have led to creation of side chapels and altars which were spon-sored by benefactors, who received Holly Masses, celebrated for them, and pastoral care in exchange.The 1632 constitutions of Pope Urban the 8th together with order’s etiquette from 1759 are re-affirming the original message of Franciscan temples. It is based on mys-teries of salvation which are represented by the crucified Jesus Christ, the Immaculate Conception of Virgin Mary and Franciscan Saints who with their lives example have shown a way to glory. The idea of Franciscan devotion is represented in dedicated altars and ceremonial processions.In modern age, churches of Friars Minor Conventual were constantly influenced by changes of Renaissance (15th century) and Baroque (from 18th century), which composition was totally different from Gothic. However, despite some architectural changes, the Franciscan idea of devotion, which was included in the plan of churches, has remained the same.The analysis of sacral space in Franciscan churches which has been conducted in this article heads to a conclusion of constant development of Franciscan churches interiors. The changes which took place during 13th and 18th centuries were dictated by evolution of order’s spirituality and needs of believers.

Abstract:
The chapter deals with the role of the Virgin Mary in the nation- state building process in Serbia. The beginning of the process of religious revival in Serbia coincided with the beginning of the social, economic and political crisis in the former Socialistic Federative Republic of Yugoslavia, which took place at the beginning of the 1990s. There was an urgent need to find new collective identity, since the earlier had been reduced to rubble. At the individual level, this process primarily implied increased participation in rites within the life cycle of an individual (baptism, wedding, and funeral), followed by popularisation of the practice of celebrating family's patron saint days and, only in the end and on the smallest scale, by an increase in the number of believers taking an active part in regular church services. On the collective level, the traditional closeness of the Serbian Orthodox Church and Serb people and the state was the basic paradigm of such restructuring. The attempt to establish continuity with the tradition of the medieval Serb state, which implied active participation of the Church in both social and political matters, as well as the grafting of this relationship in the secular state and civil society in Serbia at the end of the second millennium, turned out to be a multi-tiered issue (Jevtić 1997). At mass celebrations, as well as at revolutionary street protest rallies (which were plentiful in the capital during the last dozen years or so) and at celebrations of the town's patron saint days and various festivities, the image of the ‘Bogorodica’ [Gr. ‘Theotokos’, i.e. The Mother of God]; appears. Leading the processional walks of the towns, it emerges as a symbol which manages to mobilise the nation with its fullness and multi-layered meaning. The main thesis of the chapter is to explain the historical roots of her cult and her embeddedness in the national history and identity in Serbia. The cult of the ‘Bogorodica’ has always had greater importance on the macro than on the micro level. This is corroborated by the fact that a relatively small number of families celebrated some of the ‘Bogorodica’ holidays as their Patron St Day, while a large number of monasteries and churches, as well as village Patron St Days were dedicated to one of them (Grujić 1985: 436). On the other hand, some authors believe that, with the acceptance of Christianity, it was the cult of the ‘Bogorodica’ which was the most developed among the Serb population, because her main and most widely recognisable epithet Baba, connected to giving birth, was directly associated with the powerful female pagan divinities such as the Great Mother, Grandmother etc. (Petrović 2001: 55; Čajkanović 1994a: 339). In the folk perception, the ‘Presveta Bogorodica’ [The Most Holy Mother of God] is unambiguously connected to the phenomenon and process of birth-giving and, that is why, barren women most frequently addressed the ‘Bogorodica’ for assistance. The observance of the image of the ‘Bogorodica’ was specifically connected with the so-called miracle icons, that is, her paintings linked to some miraculous event, either locally or generally. This was most frequently related to the icons which were famous for discharging myrrh, as well as icons which would ‘cry’ in certain situations, as well as those that changed the place of residence in a miraculous manner. The use of icons in wars, either those of conquest or defensive, appears to be a widely spread practice in the Orthodox world. It was noted that Serb noblemen carried standards with images of various saints to wars, and that the cities were frequently placed under the protection of certain icons. The author shows how, travelling through towns and battlefields, throughout the decades and centuries, the ‘Bogorodica’ appeared through its holy image at the end of the second millennium as the protectress, advocate, Pointer of the Way and foster mother of those who were, possibly more than ever, in need of miracles and waymarks.

Abstract:
Abstract LCOE reduction in FOWTs is heading to larger wind turbines in order to increase power production and capacity. NREL and DTU have recently developed a 15MW reference wind turbine, which can be used to validate the platform concepts for the next generation of wind turbines. Increasing the power of wind turbines leads to larger platforms due to the need to withstand the increase of the weight of the Nacelle Rotor Assembly, as well as the increase of the wind forces and pitching moment. Moreover, the larger the turbines and platforms the larger surge/sway and yaw unbalanced forces, which

Abstract:
Hole-pattern annular gas seals have been proven to be very effective in reducing leakage flow between high and low pressure sections in turbomachinery. This type of seal has two distinct flow regions: an annular jet-flow region between the rotor and stator, and cylindrical indentions in the stator that serve as cavities where flow recirculation occurs. As the working fluid enters the cavities and recirculates, its kinetic energy is reduced, resulting in a reduction of leakage flow rate through the seal. The geometry of the cylindrical cavities has a significant effect on the overall performanc

Abstract:
The demand of further increased bypass ratio of aero engines will lead to low pressure turbines with larger diameters which rotate at lower speed. Therefore, it is necessary to guide the flow leaving the high pressure turbine to the low pressure turbine at larger diameters minimising the losses and providing an adequate flow at the LP-turbine inlet. Due to costs and weight this intermediate turbine duct has to be as short as possible. This would lead to an aggressive (high diffusion) s-shaped duct geometry. It is possible to shorten the duct simply by reducing the length but the risk of separa

Abstract:
The experimental data which will be presented in this paper are the results of the comparison between different methods for evaluating damaged surfaces by cavitation erosion. The different methods are partly working in the initial stage of cavitation erosion and partly at developed cavitation erosion, where mass loss occurs. The used test rig consists basically of a rotating disc with a diameter of 500 mm on which four holes are located. Each hole generates a cavitation zone while the disc is rotating. The test objects are material specimens made of copper. Copper was used as test material in

Abstract:
An important goal in the development of turbine bladings is to increase the efficiency in order to achieve an optimized use of energy resources. For that purpose a detailed understanding of flow phenomena is required. This paper presents an experimental investigation of the impact of varying blade loadings on the flow field and leakage flow. The investigations were conducted on a 2-stage axial turbine at the Institute of Steam- and Gas Turbines, RWTH Aachen University. The flow field for different blade loadings has been determined at the inlet and outlet as well as between the two stages. Con

Abstract:
Vegetation inventory and mapping is a process to document the composition, distribution and abundance of vegetation types across the landscape. The National Park Service’s (NPS) Inventory and Monitoring (I&M) program has determined vegetation inventory and mapping to be an important resource for parks; it is one of 12 baseline inventories of natural resources to be completed for all 270 national parks within the NPS I&M program. The Mojave Desert Network Inventory & Monitoring (MOJN I&M) began its process of vegetation inventory in 2009 for four park units as follows: Lake Mead
