Monitoring Acid-Stimulation Treatments With Slickline Distributed-Temperature Sensing
Authors: Carpenter Chris
Published: May 2016

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 173640, “Monitoring Acid-Stimulation Treatments in Naturally Fractured Reservoirs With Slickline Distributed-Temperature Sensing,” by Stephen Grayson, SPE, Yosmar Gonzalez, Kevin England, SPE, Ryan Bidyk, and S. Farrell Pitts, SPE, Schlumberger, prepared for the 2015 SPE Coiled Tubing and Well Intervention Conference and Exhibition, The Woodlands, Texas, USA, 24–25 March. The paper has not been peer reviewed.

Mechanical-diversion techniques can ensure acid injection into the various intervals of naturally fractured reservoirs. With these methods, surface pressure can be monitored to assess fluid-placement effectiveness for each zone treated, but uncertainty of the friction pressure in the pipe while pumping can result in an incorrect interpretation of fluid entry. A new technique using fiber-optic distributed-temperature-sensing (DTS) measurements offers a solution when bullheading by providing an indication of where the acid has been injected into the fractured reservoir.

Introduction

The variability of fracture density and aperture along with fluid conductivity poses challenges to the goal of achieving uniformity of acid distribution to all fractures in a well. The optimum technique would allow effective treatment of all fractures, be operationally efficient, and facilitate the determination of treatment effectiveness in real time.

Diversion of the treatment fluid helps ensure that the entire interval is stimulated effectively on the basis of design objectives. When diversion is not considered, there is a significant reduction in the ensurance of complete zonal coverage. In the past, the rule of thumb has been to recommend diversion when attempting matrix stimulation of more than 20 ft of zone.

Diverters can be separated into two broad categories, mechanical and chemical.

Mechanical diversion is the category that comprises devices such as staged completion systems, bridge plugs and packers, straddle packers, balls and baffles, and sliding sleeves.

Chemical diversion relies on the ability to perform an action to reduce fluid injection into these zones taking most of the early-time injection fluid and to redistribute the injection to other regions of the formation that also need to be stimulated.

Mechanical diversion is the most certain option for ensuring that the treatment fluid is pumped into the intended zone. This is achieved by positive isolation within the wellbore and the requirement of hydraulic zonal isolation on the outside of the pipe for cased-and-cemented wells. A straddle packer that can be set and unset multiple times or opposing swab cups are very effective when run on coiled tubing. They can also be run on jointed pipe with a workover rig, but there are significant additional complexity and safety considerations with this option. Ball sealers have been used for many years and can be effective under certain conditions.
Development of Drillpipe-Riser-Intervention Systems Offshore West Africa
Authors: Carpenter Chris
Published: May 2016

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 170308, “Drillpipe-Riser-Intervention-System Successful Experience in Offshore West Africa,” by Henri de Fonvielle and Laurent Bordet, Vallourec Drilling Products; William Campbell and Nenad Susak, Total; and Mitra Marajh, FMC Kongsberg International, prepared for the 2014 SPE Deepwater Drilling and Completions Conference, Galveston, Texas, USA, 10–11 September. The paper has not been peer reviewed.

This paper details the technical and economic challenges in west Africa that have led to the design of drillpipe-riser-intervention-system (DPRIS) solutions. Depending upon the field requirements, two different types of drillpipe-riser systems using a proprietary double-shoulder connection have been used by operators. A first solution was developed in 1999 featuring a seal ring close to the external shoulder. Subsequently, a new solution featuring a gas-tight metal-to-metal seal on the pin nose was developed.

Introduction

Well-completion and -intervention operations in offshore environments are growing in complexity because of increasing water depths and working- pressure requirements. These environmental factors are having a major effect on tubebody minimum-tensile-load capacity and gas-tight-connection requirements. As early as 1996, an operator accelerated the development of a new type of completion and intervention system when it discovered the Roncador field in 1800 m of water offshore Brazil. A dedicated project team was created to develop the DPRIS. The operator had already identified its need for a mobile early-production riser for use with a floating production unit performing extended flow testing of production wells. The new DPRIS could be used for subsea tubing-hanger and production-tree installations and as an early-production riser.

DPRIS use has greatly expanded; more than 50 systems currently operate in deepwater offshore regions. The first use of the system in west Africa occurred in 1999 on the Girassol project. A second-generation drillpipe riser has since been designed featuring new connection designs and hydrogen-sulfide-resistant materials and has been subject to evaluation, testing, and field performance.
Field Pilots Show Effectiveness of Foams in Low-Porosity Naturally Fractured Reservoir
Authors: Wilson Adam
Published: May 2016

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper IPTC 17950, “Foams Prove Effectiveness for Gas-Injection Conformance and Sweep-Efficiency Improvement in a Low-Porosity Fractured Reservoir—Field Pilots,” by A. Ocampo, SPE, A. Restrepo, N. Rendon, J. Coronado, J. Correa, D. Ramirez, M. Torres, and R. Sanabria, Equion Energia, and S. Lopera, National University of Colombia, prepared for the 2014 International Petroleum Technology Conference, Kuala Lumpur, 10–12 December. The paper has not been peer reviewed.

Foams have proved to be efficient at temporarily blocking high-conductivity layers and improving gas-injection conformance and sweep efficiency in predominantly matrix reservoir systems, at least in laboratory and field pilot tests. However, their successful use in naturally fractured reservoirs has yet to be fully demonstrated. This paper presents the evaluation process and the successful results for two foam-enhanced-oil-recovery (EOR) field pilots.

Introduction

The Recetor area corresponds to the northern extension of the larger Cupiagua field, which is 115 km northeast of BogotÁ in the foothills of the Eastern Mountain chain in Colombia. The main reservoir is the Mirador formation, a quartzarenite with matrix porosities between 3 and 9% and permeabilities in the range of 0.01 to 10 md, located below 13,000-ft true vertical depth subsea.

In the Recetor area, the fracture corridors are confirmed to play an important role both in well productivity/ injectivity and in interwell connectivity and gas channeling between gas injectors and oil producers. This is confirmed by the high connectivity between most of the wells and the observed levels of gas recycling, which could not be explained by the low matrix permeabilities. Current condensate recovery factor is approximately 34%, and steep evolution of gas production has been observed in the wells influenced by the two main gas injectors (LR YR-7 and LR YZ-11) during the last 2 years, with gas/ oil ratios (GORs) ranging from 40,000 to 100,000 scf/STB.

The foam-EOR pilot projects in the Mirador formation of the Recetor area were aimed at controlling, or at least mitigating, the high levels of gas recycling between the main gas injectors and their respective oil producers. They were engineered to improve both the vertical conformance of the gas at the injector wells and the sweep efficiency deep into the reservoir, by use of limited slugs of liquid foaming solutions followed by gas injection.
A Coffin Dispersed: Case-study of 21st Dynasty Coffin Fragments (Timişoara 1142–1146, Budapest 51.325)
Authors: Anđelković Branislav , Teeter Emily
Published: May 2016

Study of the iconography and texts on sections of a 21st Dynasty coffin in the collection of the Museum of Banat in Timişoara, Romania, shows that the vignettes as well as the texts are unusual for such coffins. A notable feature is that the deceased is nowhere shown on the fragments, and bands of text (that on other coffins end with the name of the deceased) fill the entire area leaving no room to add the personal name.The lack of a name, the corrupt texts, unusual iconography, and the lack of varnish may reflect the lack of resources of the coffin’s owner. A fragment in Budapest (51.325) is shown to join the Timişoara coffin sections. The dismantling/sawing of an object to make it more portable and saleable reflects an established practice of late 1800s and early 1900s Egyptian antiquities market.
"Eschatological" debate on the future of anthropology. Concept of crisis of anthropology in proceedings “The End of Anthropology”
Authors: Ignjatović Suzana
Published: May 2016

The paper deals with the current concept of “anthropology in crisis”, based on the collection ofpapers “The End of Anthropology”, dedicated to this particular issue. The positions presented in this book are used as a starting point for further discussion about the crisis discourse in anthropology. The paper critically examines the identified sources of crisis (interdisciplinarity, professionalization, etc) but also refers to other aspects of crisis that should be further discussed (relativism, applied anthropology, political aspects of anthropology).
The Myth of Huitzilopochtli: Diachronic and Structural Interpretation
Authors: Seke Igor
Published: May 2016

The paper investigates the myth about the birth of Huicilopochtli, the deity considered by the Spanish conquistadors to be the supreme god of the Aztecs. Aztec myths are even today usually interpreted diachronically, strictly following the sequence of events. Structural analysis, on the other hand, in attempting to uncover the message a myth holds, doesn’t deem the sequence of events in the story important, but rather, studies the interrelation of chains of essential units of myth – mythemes. These two kinds of analysis provide two different interpretations of the same myth: while formal analysis gives a cosmological interpretation, structural analysis points to the powerful social contradictions which this myth tries to reconcile.
Postmodernist marketing
Authors: Radenković-Šošić Biljana
Published: May 2016

The traits of postmodernist communication with consumers are based on the transmission of postmodernist concepts in the area of marketing and communication with consumers. The paper offers an overview of the basic semiological points of interpretation of commercial messages, especially the semiotic square pioneered by Jean-Marie Floch, as well as offering an analysis of commercial messages according to the most prominent traits of postmodernist marketing: creating the effect of hyperreality, fragmentary communication, and displacement of reality, bringing opposites together and accepting difference. The results of the analysis confirm the hypothesized high level of congruence of certain postmodernist traits of marketing with messages which emphasize the ludist and utopian values of products.
Creating context: Ethnography and local concept „both a man and a woman“ in the Roma community in Skopje
Authors: Crvenkovska-Risteska Ines
Published: May 2016

The research in this text focuses on creating a research context, which reflects the notion of sexuality of individuals born as male and feeling as „women“ or „as both male and female“ in the Roma community in Skopje. The ethnographic „field“ is created nontraditionally and reflects the characteristics of the local sex/gender „both male and female“ concept, which leads to the systemic characteristics in the local economies where sexuality acquires an economic form.
Serious games: Theory in anthropology since the 1980s
Authors: Bošković Aleksandar
Published: May 2016

The paper presents a critical overview of recent theories in anthropology, particularly following Ortner’s groundbreaking 1984 summary, as well as debates opened up by the Writing Culture symposium and the book that followed (Clifford and Marcus 1986).  Beginning with Ortner’s theory of practice, the author presents basic elements of several theoretical currents that influenced anthropology’s development in the last few decades, with particular emphasis on the use of the concept of culture. Post-1980s years provided for increased visibility of other anthropologies, outside of traditional “centers” of anthropological knowledge (i.e. Anglo-American, French and German anthropologies).Some representatives of these traditions, together with certain modifications of structuralism, aided by representatives of the “deconstructionˮ movement (especially in France), additionally influenced the self-questioning in contemporary anthropology, leading gradually to what is sometimes referred to the “ontological turnˮ in contemporary anthropology, exemplified by the Brazilian anthropologist Eduardo Viveiros de Castro. Representatives of this “turn” also see themselves as successors of the theory of practice. The author points to some serious implications of this “turnˮ – including pushing anthropology into the realm of pseudo-science, and making it completely irrelevant for understanding and interpretation of the contemporary world.
Vuk’s Parliament as an element of intangible cultural heritage in tourism offer of Serbia
Authors: Bjeljac Željko , Terzić Aleksandra
Published: May 2016

During the process of choosing the first group of intangible cultural heritage assets as a part of national database of National committee and Center for intangible cultural heritage, in 2012 to national register as an element of intangible cultural heritage entered the cultural event “Vuk’s parliament” (Tršić). Even though, at the first sight, the question of why one cultural event is considered to be the part of intangible heritage could be made, it can be said that Vuk’s parliament is among the oldest cultural events in Serbia, and that it has its own cultural, linguistic, folkloristic, and touristic significance. This paper places the focus on touristic significance, based on the fact that this event is visited by several dozen thousand visitors from Serbia and abroad. The main goal of this research is to determinate how this event as intangible cultural heritage of Serbia could in fact become representative tourist attraction.
Of Kimchi, Caribou - and Canadian Multiculturalism? An exploratory study
Authors: G Hallsworth Alan , Wong Alfred , Choi Eunyoung [Christina]
Published: May 2016

In this paper we argue that food – a basic life-necessity – should not be overlooked as a dimension of life-satisfaction. We use secondary sources and also empirical research to illustrate emergent dimensions of this topic: primarily in British Columbia, Canada. Other recent research suggests that, among immigrant populations, life satisfaction in a multicultural society such as Canada is not just about getting a job. As people migrate, they move into a new environment that may, or may not, supply familiar necessities. The additional perspective here is that off-reservation access to appropriate food by First Nations is also considered.
The Serbian family in the late Middle ages
Authors: Mišić Siniša
Published: May 2016

Marriage in Serbia in the middle ages was conducted only between persons belonging to the same social class. It was arranged and the woman would bring a dowry which would be controlled by the husband as long as the marriage lasted. Male children would inherit their father. Daughters played a significant role in connecting families through marriage. A man, unlike a woman would not bear any consequences in case of adultery. The consequence of this was a large number of extramarital children.

In the Serbian state in the middle ages the family, or the “home” (kuća as it is named in sources), was the basic unit of society. The family could be nuclear or cooperative. Through the analysis of diplomatic data, as well as the first Turkish books – defters, one can see that one quarter of the population lived in nuclear families. More than half of the families which lived in cooperative arrangements were made up of small cooperatives numbering no more than two or three members. Almost all cooperative families were made up of father-son or brotherly cooperatives. The type of cooperative was largely influenced by the length of life or the capability of giving birth. The source material shows a small number of large cooperatives.

Nuclear families and cooperative families are present in both the nobility and the small folk (dependents). There is no difference in the family structure with regard to social status. Nuclear families are omnipresent, and the characteristics of cooperative families are the same in nobility, serfs, sokalniks (a class a little above the serfs, who were most often servants, with certain privileges), priests, repairmen or fishermen. The difference is seen only within the Vlach population where in the cooperative there are more sons in law than in other populations. This is the result of an attempt of an agrarian population to move toward the status of herdsmen which was more favorable for them.
A new life on the small screen and around it: The beginnings of television in socialist Yugoslavia (1955-1970)
Authors: Erdei Ildiko
Published: May 2016

Ever since television became institutionalized in socialist Yugoslavia in the late 1950’s, it was closely associated with the idea of a “new life” in socialist society. As a new technology, as a modern object in the socialist household, and as a medium which enabled the transmission of desirable content for creating socialist citizens and shaping models of socialist “culturality” and entertainment, television represents a prime terrain for studying the transformations of culture and society in the latter half of the 20th century in Yugoslavia, as well as in the rest of Europe and the world. The paper is mostly based a number of key sources, memoirs, which speak of the history of television in Yugoslavia from the point of view of creators and a wider circle of experts who were involved in it. In this paper I will attempt to shed some light on the dynamics of the process of introducing television into Yugoslavian society, the perplexities, confusions and tensions which this new technology – simultaneously the product and the mediator of modernity – brought with it. Special attention is given to the relationship between television as technology and television as a medium of mass communication, which permanently marked the beginnings of television in Yugoslavia with the tension between “tech” and “programming”, as well as to the role of television in everyday life.
From feeling to naming: A sensitive approach to managerial newspeak through bullying at work
Authors: Vandevelde-Rougale Agnès
Published: May 2016

By accessing language, an individual is granted the means to represent experiences and to share meaning. However, ill-being resulting from workplace bullying makes it hard for the subject to put his/her experience into words. I explored this uneasiness through qualitative research conducted through an interdisciplinary approach. My fieldwork led me to raise questions about the influence of modern managerial discourse on the individual and his/her relation to language. After conducting in-depth interviews with individuals confronted with bullying at work and crossing their narratives with information from organisational websites, I suggest that modern managerial discourse hinders the expression of emotions and thereby the understanding of subjective experiences (both the informants’ understanding of their own subjective experience and the understanding of their experiences by others). I argue that this process is rooted in an internalization of managerial discourse, which weakens the subject as it diminishes his/her enunciative autonomy and limits his/her ability to make sense of his/her emotional experiences. This article considers these findings. Through excerpts from organisational communications, the first part calls on the heuristic dimension of knowing via the senses to question the subjective influence of managerial discourse. The narrative of an experience of workplace bullying then allows for display of the ambivalence of managerial discourse. It appears to be a tool both enabling and hindering subjective expression, as it allows sharing of facts at the expense of sharing emotions. Considering my argument that the internalization of managerial discourse by the subject turns this discourse into “managerial newspeak”, the third and concluding part of the article addresses the issue of sharing understanding of psychosocial processes in scientific work.
The description and symbolic value of the unicorn in French literature of the 12th and 13th centuries
Authors: Panić Marija
Published: May 2016

The paper considers naturalist and symbolic traits attributed to the unicorn in French 12th and 13th century literature. The corpus encompasses the bestiaries comprised by Philippe de Thaon, Gervaise, Guillaume de Normandy, Pierre de Beauvais, Richard de Fournival and pseudo-Pierre de Beauveis, which belong to the tradition of the Physiologoi, as well as other encyclopedic and other works which contain the bookish zoological and geographic knowledge of the middle ages: Mappemonde by Pierre de Beauvais, The letter of presbyter John, and the Mappemonde by Gossouin de Metz. In this corpus where the description of the animals comes mainly from the same written sources (from antiquity and late antiquity and the Bible), we consider how this nonexistent animal is described and to what extent a symbolic interpretation is present.
Objects or Narratives. Archaeological Displays in Serbia: The Age of Artefacts
Authors: Cvjetićanin Tatjana
Published: May 2016

There are over 60 museums and collections in Serbia today holding archaeological material and archaeological displays, offering an ever-present, public image of the results of the development of archaeological discipline in our country, its theoretical framework, and above all, present the official interpretation of the past. In spite of the fact that displays and exhibitions represent the most visible museum forum and the basic medium of museums, presenting official representations of the past, constructing memories, forming values and attitudes, these are rarely the object of consideration from the theoretically informed perspective. The aim here is to consider the characteristics of the archaeological displays and thematic exhibitions in Serbia, and especially of the National Museum in Belgrade after the World War II, since this institution is still the paradigm of museum archaeology in the country. The questions are raised whether the changes in the archaeological theory, and especially in museology, have induced the changes in the custodians' practice; whether the deeply rooted dominant archaeological concepts have been transformed; finally, and perhaps more importantly, whether the mission of museums has changed. The interpretive context is still completely based upon the culture-historical approach and the idea of continuity, and the past is presented by rarities and utmost achievements, mainly estheticized. Museums and museum archaeology have travelled along the road from research institutions, whose expertise is not challenged, temples of knowledge and sanctuaries of the past in which the national idea slowly enters the focus, to the marginalized cultural institutions trying to become relevant to the community.
Inscriptions on the Interior of the 30th Dynasty Coffin of Nefer-renepet from Akhmim
Authors: Anđelković Branislav , P. Elias Jonathan
Published: May 2016

The anthropoid wooden coffin with plinth (L. 183.5 cm), datable to the mid-4th century B.C. (30th Dynasty), names Nefer-renepet, a dancer of Min from Akhmim. This object represents one of the artistically and technically superior coffins produced by late Egyptian coffin workshops. It was formerly part of the Amherst collection, and was purchased by Ernest Brummer at a Sotheby, Wilkinson & Hodge auction in London in 1921, then donated the same year to the National Museum in Belgrade. The interior of the lid is distinguished by a remarkable ‘gliding Nut motif with upward streaming hair’ (an extremely important iconographic element) while the interior of the trough is dominated by a line drawing of Imentet wearing a diagonally-veined maat-feather on her head. The interior decoration includes inscriptions written on the side facets. Written hastily in whitish-yellow line on a rough ground of thick black pigment (in contrast to the fine outer decoration of the coffin) these barely legible Stundenwachen texts, are nonetheless significant, and are to be identified as abbreviated texts derived from the Book of Day and Book of Night. They are a manifestation of Late Period magical symbolism stemming from New Kingdom funerary compositions. Their presence on the coffin, however hurried, was intended to ease Nefer-renepet’s passage through the netherworld. Since 1992 the coffin of Nefer-renepet is kept in the Archaeological Collection of the Faculty of Philosophy, University of Belgrade.
Skeuomorphism, Boundary Objects and Socialization of the Chalcolithic Metallurgy in the Southern Levant
Authors: Gošić Milena
Published: May 2016

Metalworking emerged in the southern Levant as a new ritual practice during the late phase of the Ghassulian culture, ca. 4300–3900 BC. Ghassulian metalworkers cast objects in both pure and alloyed copper. All the artifacts produced during this time span were ritual. The aim of the present paper is to discuss the socialization process of the Ghassulian metallurgy and its copper objects, by using the concepts of skeuomorphism and boundary objects. Ghassulian copper artifacts can be divided into two groups. The first group consists of artifacts, such as maceheads, chisels and axes, which were produced in stone before the Ghassulian metallurgy appeared. The second group consists of artifacts produced only in metal, including scepters, standards, “crowns” and horns, which were decorated by motifs found on various other early and late Ghassulian ritual artifacts. The artifacts of the first group are skeuomorphic objects, the morphology of which was widely recognized in early and late Ghassulian contexts. These were boundary objects, belonging both to the realm of the new social world of metallurgy and the preexisting world of Ghassulian ritual behavior. Their purpose was to introduce metallurgy to people, both in the Beer Sheva settlements and in other parts of the southern Levant, who did not practice it, as a technology firmly rooted in the Ghassulian tradition. The second group consists of more innovative objects that demonstrated the transformational potential of metallurgy and the superior control metalworkers had over the material world.
Conceptions of sex in movies about the post-apocalypse
Authors: Banić Grubišić Ana
Published: May 2016

The paper deals with ways of representing sexual relations in movies about the post-apocalypse. Different forms of sexual relations which occur in a post-apocalyptic setting are considered with regard to two types of communities/societies which emerge after the end of the world. These movies indicate how much the idea of an instinctual, natural, biological sexuality is widespread in popular imagination – in the post-apocaypse sex is represented as a motivational force on par with hunger.
Anthropological reading of science fiction
Authors: Gavrilović Ljiljana , Kovačević Ivan
Published: May 2016

The paper gives an overview of the prevalence of the analysis of science fiction literature and science fiction in other segments of popular culture in Serbian anthropology. This overview is preceded by a consideration of science fiction as a genre while keeping in mind the fluidity of the genre and the interweaving of subgenres as well as the transformations which science fiction is undergoing in certain media (books, films, TV shows and video games). In Serbian anthropology research on science fiction is more prevalent than the study of other phenomena, as the number of anthropologists whose work is represented in the paper is fairly large compared to the size of the anthropological community as a whole. The causes for this can primarily be found in a collective focus on questions such as: who are we and who the others are, what the basis of creating and building identity is or what the role of context in recognition of species is. Anthropology gives answers to these questions through the interpretation, explanation and understanding of the world around us, while science fiction does it through the literary considerations of these same questions.
How to Deal With Economic Depression: Experimental and Theoretical Lessons from the Great Depression
Authors: Radonjić Ognjen
Published: May 2016

The purpose of this paper is to explain not only why the Euro Area debt crisis does not subside, but also, why it deepens. We believe that the experience of the Great Depression can help economic theorists and officials to look at the problem from a different perspective since it is apparent that the economic orthodoxy and economic policies supported by its conventional wisdom do not provide desired results. Roosevelt's fiscal activism and Keynes' revolutionary theory deliver an answer to the question of why is, in crisis periods,  vigorous reaction of economic authorities needed and why the free market is not able by itself to find way out of the fog, which, as time passes, becomes more and more dense.
The hijab as a phenomenon of constructing and contesting identity: The example of contemporary Novi Pazar
Authors: Đurović Miloš
Published: May 2016

This paper represents a consideration and an analysis of the relationship between the hijab as an article of clothing and the female body which can be understood as a field of social relations and struggles. The covered body of Muslim women and the meanings it carries can be understood and represented through a number of aspects. The paper explains the phenomenon of the hijab as a place of constructing and contesting identity using the example of contemporary Novi Pazar. The issue of the ban on wearing the hijab, as well as other coverings worn by Muslim women – the niqab and the burka, has for years been a burning issue in many (officially) secular democratic societies. Even though this issue has not been as prevalent in the Republic of Serbia as it has been in many Western European countries, I think that an anthropological analysis of the use of the hijab in Novi Pazar – which had since the 1990s become a visible and significant element of the Sandžak cultural milieu – has both theoretical and social significance. Through the analysis of embodiment and bodily practices of young Muslim women who wear a hijab, and the consideration of the female experience and the personal relationship of the women themselves to the body, “covering” and their identities, we are given an insight into a more personal and more intimate, but also a more open and versatile perspective.
Portraits from the second half of the 18th century in Croatia
Authors: Simončić Katarina Nina
Published: May 2016

This paper will attempt to analyze the clothing from the rococo period and underline fashion as an important segment in the reconstruction of a specific style era.  Based on conserved portraits from the second half of the 18th century, as well as rare artifacts of clothing from the period found in Croatia, a description of primarily women’s types of clothing, accessories and the terms used to describe them will be given. Influences had, primarily through cultural and trade routes, come from the fashion capital of the period – France, and fashion innovations and the intensity of their changes were under the influence of the personal style first of Madame de Pompadour and afterwards Marie Antoinette. Croatia, which had at the time been part of the Habsburg monarchy and under the Republic of Venice, tended toward French influences in fashion, which represents a considerable move from the prior influence of Italian and German style.
Jogging Therapy for Hikikomori Social Withdrawal and Increased Cerebral Hemodynamics: A Case Report
Authors: Nishida Masaki , Kikuchi Senichiro , Fukuda Kazuhito , Kato Satoshi
Published: May 2016

Severe social withdrawal, called hikikomori, has drawn increased public attention. However, an optimal
clinical approach and strategy of treatment has not been well established. Here, we report a case of hikikomori for which an exercise intervention
using jogging therapy was effective, showing cerebral hemodynamic improvement. The patient was a 20 year old Japanese male who was hospitalized in order
to evaluate and treat severe social withdrawal. Although depressive and anxiety symptoms partially subsided with sertraline alone, social withdrawal persisted due to a lack of self confidence. With his consent, we implemented exercise therapy with 30 minutes of jogging three times a week for three months. We did not change the pharmacotherapy, and his social withdrawal remarkably improved with continuous jogging exercise. Using near infrared spectroscopy to evaluate hemodynamic alteration, bilateral temporal hemodynamics considerably increased after the three-month jogging therapy. Regarding exercise therapy for mental illness, numerous studies have reported the effectiveness of exercise therapy for major depression. This case implied, however, that the applicability of exercise therapy is not limited to major depressive disorder. Jogging therapy may contribute to reinforcing self confidence associated with “resilience” in conjunction with neurophysiological modulation of neural networks.

Risk Factors for Primary Open Angle Glaucoma (POAG) Progression: A Study Ruled in Torino
Authors: Actis A.G. , Versino E. , Brogliatti B. , Rolle T.
Published: May 2016

Purpose:

Aim of this retrospective, observational study is to describe features of a population sample, affected by primary open angle glaucoma (POAG) in order to evaluate damage progression on the basis of the emerged individual risk factors.

Methods:

We included 190 caucasian patients (377 eyes), evaluating relationship between individual risk factors (explicative variables) and MD (Mean Deviation) of standard automated perimetry. We also considered the dependent variable NFI (Neural Fiber Index) of GDx scanning laser polarimetry. Progression has been evaluated through a statistic General Linear Model on four follow up steps (mean follow up 79 months).

Results:

Factors reaching statistical significance, determining a worsening of the MD variable, are: age (P<0.0001), intraocular pressure (IOP) at follow up (P< 0.0001), female gender (P<0.0001), hypertension (P< 0.0001) and familiarity (P= 0.0006).

Factors reaching statistical significance, determining a worsening of the NFI variable, are only IOP at follow up (P= 0.0159) and depression (P= 0.0104).

Conclusion:

Results of this study confirm and enforce data coming from most recent studies: IOP remains the main risk factor for glaucoma assess and progression; age and familiarity are great risk factors as underlined in the last decades; female sex can be an important risk factors as emerged only in the last years; arterial hypertension should always be evaluated in timing of our clinic follow up.
A Numerical Model for Pre-Monitoring Design of Historical Colonnade Courtyards: The Case Study of Chiaramonte Palace in Palermo
Authors: Bilello Cristiano , Greco Emilio , Greco Martina , Madonia Nazareno , Pirrotta Antonina , Sorce Antonio
Published: May 2016

This paper proposes a numerical model that can be used for theoretical and experimental dynamic characterization of historical colonnade courtyards. Such an architectural element appears often in buildings of historical heritage and, especially under seismic excitation, it represents the most vulnerable structural part. Therefore, it is very important to have reliable as well as simple models available for vulnerability analysis, to evaluate different reinforcing systems if needed, or to plan dynamic characterization tests or monitoring campaigns, as in the present case. Chiaramonte Palace, a wonderful example of the historical heritage of Palermo, is investigated as case study. Firstly, a review of the restoration and structural consolidation works made over the years is presented, as fundamental step towards the knowledge of any existing structural system. Then the acquired information are used to propose a simplified finite element model that properly accounts for the interaction with the surrounding part of the building, and that can be easily calibrated on the basis of estimated or measured vibration periods.
Solutions for the Design and Increasing of Efficiency of Viscous Dampers
Authors: Alotta G. , Cavaleri L. , Paola M. Di , Ferrotto M.F.
Published: May 2016

In last decades many strategies for seismic vulnerability mitigation of structures have been studied and experimented; in particular energy dissipation by external devices assumes a great importance for the relative simplicity and efficacy. Among all possible approaches the use of fluid viscous dampers are very interesting, because of their velocity-dependent behaviour and relatively low costs. Application on buildings requires a specific study under seismic excitation and a particular attention on structural details. Nevertheless seismic codes give only general information and in most case the design of a such protection systems results difficult; this problem is relevant also in Italy where last seismic code (NTC 2008) on one hand has increased the performance level to be attributed to buildings, especially public and strategic, on the other hand does not give a guide for the design of external dissipation devices as fluid viscous dampers or others. In this study, after a general description of fluid viscous dampers and the criteria of applying on buildings, a simplified procedure for the design of these devices is discussed also by means an application.

Ancient columns, made with a variety of materials such as marble, granite, stone or masonry are an important part of the European cultural heritage. In particular columns of ancient temples in Greece and Sicily which support only the architrave are characterized by small axial load values. This feature together with the slenderness typical of these structural members clearly highlights as the evaluation of the rocking behaviour is a key aspect of their safety assessment and maintenance. It has to be noted that the rocking response of rectangular cross-sectional columns modelled as monolithic rigid elements, has been widely investigated since the first theoretical study carried out by Housner (1963). However, the assumption of monolithic member, although being widely used and accepted for practical engineering applications, is not valid for more complex systems such as multi-block columns made of stacked stone blocks, with or without mortar beds. In these cases, in fact, a correct analysis of the system should consider rocking and sliding phenomena between the individual blocks of the structure. Due to the high non-linearity of the problem, the evaluation of the dynamic behaviour of multi-block columns has been mostly studied in the literature using a numerical approach such as the Discrete Element Method (DEM). This paper presents an introductory study about a proposed analytical-numerical approach for analysing the rocking behaviour of multi-block columns subjected to a sine-pulse type ground motion. Based on the approach proposed by Spanoset al.(2001) for a system made of two rigid blocks, the Eulero-Lagrange method to obtain the motion equations of the system is discussed and numerical applications are performed with case studies reported in the literature and with a real acceleration record. The rocking response of single block and multi-block columns is compared and considerations are made about the overturning conditions and on the effect of forcing function’s frequency.

The microstructures of dissimilar metal welds between 9Cr-1Mo (Modified) (P91) and austenitic stainless steel (AISI 304) with Ni-based alloy interlayers (Inconel 625, Inconel 600 and Inconel 800H) are reported. These interlayers were deposited by the friction surfacing method one over the other on P91 alloy, which was finally friction welded to AISI 304. In this paper, the results of microstructural evolution in the friction surfaced coated interlayers (Inconel 625, 600, 800H) are reported. For comparative purposes, the microstructures of consumable rods (Inconel 625, 600, 800H) and dissimilar metal base metals (P91 and AISI 304) were also reported. Friction surfaced coatings exhibited dynamic recrystallization. In friction surfaced coatings, the carbide particles were found to be finer and distributed uniformly throughout the matrix, compared to their rod counterparts.
Seeking Dhasa; Finding Lhasa: Liminality and Narrative in the Tibetan Refugee Capital of Dharamsala
Authors: Siganporia Harmony
Published: May 2016

This article explores the role of narrative and narrativity in stabilising identity in an exile setting, read here as a way to avert what Bjørn Thomassen calls the ‘danger’ inherent to liminality. It does this by analysing the shape and visualscape of the little Himalayan town of Dharamsala, which serves as the secular and religious ‘capital’ of Tibetan exile. It attempts to decode the narratives which allow ‘Dhasa’, as Dharamsala is colloquially known, to cohere and correspond to its metonymically aspirational other – Lhasa, the capital of old Tibet. There can be read in this act of assonant naming the beginnings of a narrative geared towards generating nostalgia for a lost homeland, alluding to the possibility of its reclamation and restitution in exile. This article explores how this narrative is evidence of the fact that it is in indeterminacy; in liminality in other words, that the ‘structuration’ that Thomassen proposes, becomes possible at all. Even as it alludes to the impossibility of transplanting cultures whole, the article also examines closely the Foucauldian notion of ‘trace residue’ inherent to ruptures in prior epistemes, treating this idea as central to creating new-‘old’ orientations for this refugee community in exile. Following Thomassen and Szakolczai, liminality is here treated as a concept applicable to time as well as place; individuals as well as communities, and social ‘events’ or changes of immense magnitude. It is this notion of liminality that the article proposes has to be a central concept in any exploration of exile groups which have to live in the spaces between the shorn identity markers of the past – rooted as these must be in a lost homeland – and the present, where they must be iterated or man-ufactured anew.
On the Edge of Existence: Malian Migrants in the Maghreb
Authors: Richter Line
Published: May 2016

Based on ethnographic fieldwork among Malian migrants and migration brokers in Mali, Algeria, Morocco, and France, this article investigates life in exile on the edge of Europe. Zooming in on the experiences of interlocutors in Morocco and Algeria, the article will explore the experiential dimensions of living in an extended liminality. Anthropologically, life in so-called places of transit, such as the Maghreb countries, has often been dealt with through the lens of liminality. In this article my aim is to build on the insights from such endeavors, and re-orient the focus by illuminating what this specific type of permanent liminality entails. I posit that a more suitable term to call this is ‘limbo’. This, I argue, consists of three main features. First, the motivation for leaving Mali is for most migrants embedded in the lack of opportunities for social mobility: the Malian youth who end up leaving, are in Honwana’s words, stuck in ‘waithood’ at home, in what many argue is a liminal social position. Second, social and political structures are not absent in the Maghreb, rather they are quite discernable and can be seen as continuations and mimicking of existing structures. Third, experiences of dramatic ruptures with humanity and morality are key characteristics of life on the edge of Europe.
Temporally Adrift and Permanently Liminal: Relations, Distalgia and a U.S. University as Site of Transition and Frontier
Authors: Karioris Frank G.
Published: May 2016

This article seeks to explore temporal reconceptualizations and forms of nostalgia that first-year university men are experiencing and creating. It will explore the ways that time can be conceived of in relation to the present and a future that is not-yet-existent. The article takes as its starting point ethnographic fieldwork in the 21st century at a private, Catholic university in the U.S. and, in particular, men in an all-male residence hall. In focusing on this hall, it means to locate and localize the thinking in the context of the 21st century as well as within the U.S., including neoliberalism as a social and economic method of relating. Through the exploration of these men’s envisioning of themselves as their future selves and the way they review the self that is now, this article makes a claim that they are – through both their actions, ways of relating, and the societal positioning – multiply liminal. Further, it will explore the way that through this temporal representation they are endowing themselves as permanently liminal both currently and in the future. The article situates these men amidst the university as an institution, as well as seeking to elucidate the importance of this temporal creation as a building of forms of transition and frontier.
Improved Direct Linear Transformation for Parameter Decoupling in Camera Calibration
Authors: Zhao Zhenqing , Ye Dong , Zhang Xin , Chen Gang , Zhang Bin
Published: May 2016

For camera calibration based on direct linear transformation (DLT), the camera’s intrinsic and extrinsic parameters are simultaneously calibrated, which may cause coupling errors in the parameters and affect the calibration parameter accuracy. In this paper, we propose an improved direct linear transformation (IDLT) algorithm for calibration parameter decoupling. This algorithm uses a linear relationship of calibration parameter errors and obtains calibration parameters by moving a three-dimensional template. Simulation experiments were conducted to compare the calibration accuracy of DLT and IDLT algorithms with image noise and distortion. The results show that the IDLT algorithm calibration parameters achieve higher accuracy because the algorithm removes the coupling errors.
