Casing design considerations for horizontal wells
No full textHorizontal Drilling is now a well established technique with growing popularity for exploiting a number of reservoirs which would otherwise be noncommercial. However, a horizontal well requires a substantial engineering work compared to conventional directional drilling. Significant advances in drilling technology have made it possible to drill horizontally in almost any situation by using very specialized tools. But some inherent weaknesses to this technique still exist, like casing design. Most of the reported horizontal wells are completed with open hole or slotted linear. This type of completion is simple and inexpensive, but may not furnish enough support to the walls of the well to allow for long well life. This paper discusses casing design considerations for horizontal wells. It addresses the type and nature of loads applied on casing strings set in horizontal wells; examples of these loads are torque and drag, formation subsidence, effect of perforations, and bending loads. A design method for casing string under loads that prevail in horizontal wells is also included. The proposed design method shows that the horizontal section needs high collapse resistance pipe or thick-wall pipe to avoid casing failure due to non-conventional loads that prevails in horizontal wells
Resurrecting Silent Histories : A Journey through the Historical Novels of Kurdish Author Jan Dost
No full textThis article explores the historical novels of Kurdish author Jan Dost, highlighting theirrole in resurrecting and preserving the silent histories of the Kurdish people. By examining Dost’sworks through the lens of Georg Lukács’s theory of the historical novel, the article delves into howDost’s narratives blend fiction with historical events to cultivate national consciousness and reconstructKurdish identity. The study discusses the evolution of the historical novel as a genre and itssignificance in Kurdish literature, emphasizing Dost’s unique contributions. It argues that the nationalistthemes and character portrayals in Dost’s novels serve as a literary mechanism to reclaim Kurdishhistory, foster collective memory, and inspire cultural resilience. This analysis aims to understandthe reasons behind the success and literary impact of Dost’s works in the broader context ofKurdish and Middle Eastern literature

A Detailed Cutaneous Manifestations Evaluation in Patients with Polycystic Ovary Syndrome
No full textBackground and Aim: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women of reproductive age. The hypothalamus-pituitary-ovary axis dysregulates in PCOS, ultimately leading to hyperandrogenisms. Consequently, it is associated with hirsutism, dyslipidemia, obesity, infertility, menstrual disturbance, and insulin resistance. To our knowledge, there is no detailed investigation of these manifestations. That is why, this study aimed to evaluate manifestations of hyperandrogenism, hirsutism in particular.
Methods: This study was performed on 39 women with an initial diagnosis of polycystic ovary syndrome. Rotterdam criteria including Oligo- or anovulation, hyperandrogenism clinical and/or biochemical signs, and ultrasound appearance of polycystic ovaries used as diagnostic criteria. Hirsutism scoring was carried out according to Freeman-Gallwey’s definition of hirsutism. The patients were analyzed for other skin problems including male pattern baldness, acanthosis nigricans, and acne as well as demographic features.
Results: Hirsutism was observed in the majority of our patients (91%) ranging from mild to severe. Concerning the distribution of hirsutism on various parts of the body, severe hirsutism was observed more on the groin, abdominal area, and chin respectively. Male pattern baldness, acanthosis nigricans, and acne, and dysregulated menstruation were reported in these patients.
Conclusion: This investigation found that skin manifestations, especially hirsutism, are highly frequent in patients with PCOS.

Adapting authoritarianism: institutions and co-optation in Egypt and Syria
No full textThis PhD thesis compares Egypt and Syria’s authoritarian political systems. While the tendency in social science political research treats Egypt and Syria as similarly authoritarian, this research emphasizes differences between the two systems with special reference to institutions and co-optation. Rather than reducibly understanding Egypt and Syria as sharing similar histories, institutional arrangements, or ascribing to the oft-repeated convention that “Syria is Egypt but 10 years behind,” this thesis focuses on how events and individual histories shaped each states current institutional strengthens and weaknesses. Specifically, it explains the how varying institutional politicization or de-politicization affects each state’s capabilities for co-opting elite and non-elite individuals.
Beginning with a theoretical framework that considers the limited utility of democratization and transition theoretical approaches, the work underscores the persistence and durability of authoritarianism. Chapter two details the politicized institutional divergence between Egypt and Syria that began in the 1970s. Chapter three and four examines how institutional politicization or de-politicization affects elite and non-elite individual co-optation in Egypt and Syria. Chapter five discusses the study’s general conclusions and theoretical implications.
This thesis’s argument is that Egypt and Syria co-opt elites and non-elites differently because of the varying degrees of institutional politicization in each governance system. Rather than view one country as more politically developed than the other, this work argues that Syria’s political institutions are more politicized than their Egyptian counterparts. Syria’s political arena is, thus, described as politicized-patrimonialism. Syria’s politicized-patrimonial arena produces uneven co-optation of elites and non-elites as they are diffused through competing institutions. Conversely, the Egyptian political arena remains highly personalized as weak institutions and individuals are manipulated and molded according to the president’s ruling clique. This is referred to as personalized-patrimonialism. As a consequence, Egypt’s political establishment demonstrates more flexibility in ad hoc altering and adapting its arena depending on the emergence of crises.
This study’s theoretical implications suggest that, contrary to modernization and democratization theory’s adage that institutions lead to a political development, politicized institutions within a patrimonial order actually hinder regime adaptation because consensus is harder to achieve and maintain. It is within this context that Egypt’s de-politicized institutional framework advantages its top political elite. In this reading of Egyptian and Syrian politics, Egypt’s personalized political arena is more adaptable than Syria’s. These conclusions do not indicate that political reform is a process underway in either state
The Last Kingdom: a Historical and Philological Study of the Netflix Series
No full textopenThis paper considers the resources behind the adaptation of “The Saxon Stories”, written by Sir Bernard Cornwell, into a Netflix TV series. The purpose of the paper is to analyse historical data and compare them to the imaginary world of the books, using a medievalist approach. At the heart of the research lie the figure of the main character, Uhtred of Bebbanburg, and the sources behind his creation. The thesis goes on examining his belonging to the archetypal hero.
The methodology then switches to a philological study of the texts, thus investigating the accuracy of the Old English words and expressions used by the author, and identifying the documents written in Old English that he may have read and used in his writing process.
The paper concludes by explaining the implications related to the creation of a modern product loaded with historical and cultural references to the Germanic world, as well as indicating possible directions for future studies within Germanic philology
Medieval language contact: an analysis of the interaction between Old Norse and Old English in "Vikings"
No full textopenThe Vikings have inspired numerous multimedia readaptations, but since they did not use writing, information about their language is scarce. Therefore, the first aim of this work will be to analyse the historical sources from which the TV series Vikings takes its inspiration, focusing on the ways in which the Viking and Old English civilizations interacted in linguistic terms. Subsequently the different arguments in this regard will be proposed, analysed and commented on, as some argue for the creation of a pidgin and creole, others argue for mutual understanding, while some others for the presence of interpreters. In conclusion there will be a focus on the theory that the author of the series decided to represent and the motivations that led him to choose it
Borges and Old English: analysis of the poem on the exploits of Beowulf, Solomon and Saturn and Battle of Maldon.
No full textreservedIl seguente elaborato ha come scopo quello di analizzare la figura del poeta argentino Jorge Luis Borges, molto conosciuto per le sue opere di genere fantastico in lingua spagnola, in relazione al suo interessamento verso la letteratura germanica. In particolare si focalizzerà sull’antico inglese, passione nata grazie alla sua curiosità verso la cultura del padre. Si parlerà della sua malattia congenita, la cecità, che lo porta a riflettere alle sue origini e a comporre saggi sull’inglese antico. Successivamente vengono illustrati alcuni dei poemi in antico inglese che ha reinterpretato in modo personale, sono i seguenti: Le gesta di Beowulf, Solomon and Saturn e la Battaglia di Moldan. L’ obbiettivo è quindi quello di mettere a confronto queste opere della letteratura germanica con l’interpretazione che ne dà Borges e di dare un quadro generale del contesto storico e della relazione tra l’autore e il mondo germanico.The aim of the following paper is to analyse the figure of the Argentine poet Jorge Luis Borges, who is well
known for his works in the Spanish-language fantasy genre, in relation to his interest in Germanic literature.
In particular, he will focus on Old English, a passion born out of his curiosity for his father's culture. His
congenital illness, blindness, which led him to reflect on his origins and compose essays on Old English, will
be discussed. Next, some of the Old English poems that he reinterpreted in his own personal way are
illustrated, they are as follows: The Exploits of Beowulf, Solomon and Saturn and the Battle of Moldan. The
aim is thus to compare these works of Germanic literature with Borges' interpretation of them and to give
an overview of the historical context and the relationship between the author and the Germanic world
Assessment of solid/liquid equilibria in the (U, Zr)O2+y system
No full textSolid/liquid equilibria in the system UO2eZrO2 are revisited in this work by laser heating coupled with
fast optical thermometry. Phase transition points newly measured under inert gas are in fair agreement
with the early measurements performed by Wisnyi et al., in 1957, the only study available in the literature
on the whole pseudo-binary system. In addition, a minimum melting point is identified here for
compositions near (U0.6Zr0.4)O2þy, around 2800 K. The solidus line is rather flat on a broad range of
compositions around the minimum. It increases for compositions closer to the pure end members, up to
the melting point of pure UO2 (3130 K) on one side and pure ZrO2 (2970 K) on the other. Solid state phase
transitions (cubic-tetragonal-monoclinic) have also been observed in the ZrO2-rich compositions X-ray
diffraction. Investigations under 0.3 MPa air (0.063 MPa O2) revealed a significant decrease in the melting
points down to 2500 Ke2600 K for increasing uranium content (x(UO2)> 0.2). This was found to be
related to further oxidation of uranium dioxide, confirmed by X-ray absorption spectroscopy. For
example, a typical oxidised corium composition U0.6Zr0.4O2.13 was observed to solidify at a temperature
as low as 2493 K.
The current results are important for assessing the thermal stability of the system fuel e cladding in an
oxide based nuclear reactor, and for simulating the system behaviour during a hypothetical severe
accident
