Experimental investigation into the effects of voids on the response of buried flexible pipes subjected to incrementally increasing cyclic loading

Aljaberi, Mohammad, Elshesheny, A., mohamed, mostafa, Mostafa, Mohamed, Sheehan, Therese 07 August 2024 (has links)
Yes / In this study, large-scale fully instrumented laboratory tests were conducted to investigate the behaviour of buried flexible high-density polyethylene (HDPE) pipes, in sand beds with and without voids subjected to incrementally increasing cyclic loading. Voids with a predetermined size were created at one side of the springlines of the pipes, which were buried at variable depths, H, of 1.5, 2.0 and 2.5 times the diameter of the pipe, D. Results showed that increasing the pipe burial depth, H/D, contributed to decreasing the settlement of the footing, deformation of the pipe crown and invert, lateral displacement of the spring-line, and the stress and strain generated along the pipe crown and invert. Void presence led to a significant increase in the footing settlement, which ranged from 3 % up to 18 %, according to H/D. Furthermore, void presence led to a sharp increase in the crown, invert, and spring-line settlements, which ranged from 34 % to 52 %, 10 %–12.5 %, and 13 %–38 %, respectively. Increasing pipe burial depth was found to be highly effective in protecting buried pipes, minimising inevitable consequences of the presence of voids. However, this was combined with an increase in the pressure at the pipe spring-line that led to a positive horizontal support at the pipe’s spring-lines resulting in reducing pipe deformation.

Religiösa föremål : En jämförande studie av vikingatida gravar från Östergötland / Religious objects : A comparative study of Viking Age burials from Östergötland

Gustafsson, Hide January 2024 (has links)
Studien handlar om vikingatida kvinnogravar från Aska, Hagebyhöga och Kvarnbacken, Vadstena. Syftet med studien är att tolka variationen av religiösa föremål i båda gravarna. Gravarnas konstruktion, innehåll och religiösa föremål jämförs i syfte att analysera om det finns likheter och skillnader, tillsammans med en teoretisk utgångspunkt i rituell praktik och genusperspektiv. Endast en grav från vardera undersökta kontexter i Aska, Hagebyhöga och Kvarnbacken, Vadstena analyseras eftersom deras religiösa föremål är mer jämförbara i denna studie. Tidigare forskning och tolkningar tillämpas för ett bredare perspektiv i variationen av religiösa föremål. Jämförelser visar likheter i gravskick och föremål som exempelvis uppsättning pärlor. Skillnader är bland annat Frejasmycket och järnstaven från graven i Aska, Hagebyhöga. I Kvarnbacken, Vadstena är krucifixet särskiljande. Variation i religiösa föremål kan tolkas som en typ av förändring i rituell praktik i Kvarnbacken, Vadstena. Religiösa föremål i Aska, Hagebyhöga tolkas ha en generationsbunden betydelse men eftersom de begravs kan det tolkas som ett avslut på äldre traditioner för kommande generationer. / This thesis concern Viking Age burials from Aska, Hagebyhöga and Kvarnbacken, Vadstena. The goal of this thesis is to interpret the variety of religious objects in the graves. The formation of the grave, its content and the religious objects is compared based on the idea of ritual practice and gender perspective. The comparison is made to analyse differences and similarities which will be interpreted. The material consist of one Viking Age female burial from each place, based on the amount of religious objects and the contemporary dating of the graves. Previous research is applied to create a wider interpretive perspective on the variety of religious objects. Comparisons show, for example, that both graves contain a collection of beads. Distinctions is, for example, the Freja pendant and the iron rod in the burial from Aska, Hagebyhöga and the crucifix from Kvarnbacken, Vadstena. The variety of religious objects can be interpreted as a form of change in ritual practice from Kvarnbacken, Vadstena. The religious objects from Aska, Hagebyhöga can be interpreted as bounded by family traditions, which could indicate an end of older traditions, based on the fact that these objects is buried.

Ring Out Your Dead : Distribution, form, and function of iron amulets in the late Iron Age grave fields of Lovö

Mattsson McGinnis, Meghan January 2016 (has links)
The purpose of this study is to analyze the distribution, forms, and function(s) of iron amulets deposited in the late Iron Age gravefields of Lovö, with the goal of ascertaining how (and so far as possible why) these objects were utilized in rituals carried out during and after burials. Particular emphasis is given to re-interpreting the largest group of iron amulets, the iron amulet rings, in a more relational and practice-focused way than has heretofore been attempted. By framing burial analyses, questions of typology, and evidence of ritualized actions in comparison with what is known of other cult sites in Mälardalen specifically– and theorized about the cognitive landscape(s) of late Iron Age Scandinavia generally– a picture of iron amulets as inscribed objects made to act as catalytic, protective, and mediating agents is brought to light.

The settlers in the Central Hill Country of Palestine during iron age I (ca1200-1000 BCE) : where did they come from and why did they move?

Russell, Irina 11 1900 (has links)
This dissertation deals with the religious practices of the settlers in the central highlands of Palestine, during the pre-monarchic period (ca 1200-1000 BCE; the so-called ‘period of the Judges’), as revealed by archaeology (cultic artifacts and sites, as well as burial customs and practices). The religious practices of the settlers have been shown to reflect continuity with, and were practically indistinguishable from, those of the Late Bronze Canaanite cult, suggesting that the majority of the settlers were originally Canaanites, most probably from the coastal city-states (ie, the religious practices have been used as an ‘ethnic marker’). It has also been proposed that one of the motivating factors for the migration of people from the coastal region to the central highlands was a fairly dramatic climatic shift, one which resulted in the area becoming increasingly and significantly drier from the late 13th century BCE until about 900 BCE. / Thesis (M.A. (Biblical Archaelogy))

Buried narratives : representations of pregnancy and burial in South African farm novels

Anthony, Loren Estelle 11 1900 (has links)
This dissertation examines the way in which South African colonial texts may be read for the historical signs they inadvertently reveal. The history of land acquisition in South Africa may be read through the representation of burial and illegitimate pregnancy in South African farm novels. Both burial and illegitimate pregnancy are read as signifiers of illegitimacy in the texts, surfacing, by indirection, the question of the illegitimacy of land acquisition in South Africa. The South African farm novel offers a representational form which seeks (or fails) to mediate the question of land ownership and the relationship between colon and indigene. In the four texts under discussion, Olive Schreiner's The Story of an African Farm, Florence Ethel Mills Young's The Bywonner[sic], Pauline Smith's The Beadle and Daphne Rooke's Mittee, the representation of burial and illegitimate pregnancy is problematic and marked by narrative displacements and discursive breakdowns. KEY TERMS burial, colonial discourse, farm novel, illegitimacy, illegitimate pregnancy, land, postcolonial theory, representation / English / M.A. (English)

Life and death : a study of the wills and testaments of men and women in London and Bury St. Edmunds in the late fourteenth and early fifteenth centuries

Wood, Robert January 2014 (has links)
The aim of this thesis is to investigate the lives of men and women living in London and Bury St. Edmunds in the late fourteenth - early fifteenth centuries. Sources studied include the administrative and legal records of the City of London and of the Abbot and Convent of St. Edmund's abbey; legislation and court records of royal government and the wills and testaments of Londoners and Bury St. Edmunds' inhabitants. Considerable research on a wide range of topics on London, but far less work on Bury St. Edmunds, has already been undertaken; however, this thesis is the first systematic comparative study of these two towns. The introduction discusses the historiography and purpose of the thesis; the methodology used, and the shortcomings of using medieval wills and the probate process. Chapter One discusses the testamentary jurisdiction in both towns; who was involved in the will making process, and the role that clerics played as both executors and scribes and how the church courts operated. Chapter Two focuses on testators' preparations for the afterlife, their choices concerning burial location, funeral arrangements and the provisions made for prayers for their souls. Chapter Three examines in detail their pious and charitable bequests and investigates what ‘good works' testators chose to support apart from ‘forgotten tithes'. The family and household relationships, including servants and apprentices, are examined in Chapter Four, exploring the differences in bequests made depending on the testators' marital status, together with evidence for close friendships and social networks. Chapter Five discusses the ownership and types of books referred to in wills and the inter-relationship between the donors and the recipients. Testators' literacy and the provision for education are also investigated.

The role of inland waters in the carbon cycle at high latitudes

Lundin, Erik January 2014 (has links)
Understanding the drivers of climate change requires knowledge about the global carbon (C) cycle. Although inland waters play an important role in the C cycle by emitting and burying C, streams and lakes are in general overlooked in bottom-up approached C budgets. In this thesis I estimated emissions of carbon dioxide (CO2) and methane (CH4) from all lakes and streams in a 15 km2 subarctic catchment in northern Sweden, and put it in relation to the total catchment C exchange. I show that high-latitude aquatic systems in general and streams in particular are hotspots for C emission to the atmosphere. Annually, the aquatic systems surveyed in this study emitted about 10.8 ± 4.9 g C m-2 yr-1 (ca. 98 % as CO2) which is more than double the amount of the C laterally exported from the catchment. Although the streams only covered about 4% of the total aquatic area they emitted ca. 95% of the total aquatic C emission. For lake emissions, the ice break-ups were the most important annual events, counting for ca. 45% of the emissions. Overall, streams dominated the aquatic CO2 emission in the catchment while lakes dominated CH4 emission, 96 % and 62 % of the totals, respectively. When summing terrestrial and aquatic C fluxes together it showed that the aquatic emissions alone account for approximately two thirds of the total annual catchment C loss. The consequence of not including inland waters in bottom-up derived C budgets is therefore a risk of overestimating the sink capacity of the subarctic landscape. However, aquatic systems can also act as C sinks, by accumulating C in sediment and thereby storing C over geological time frames. Sediment C burial rates were estimated in six lakes from a chronology based on 210Pb dating of multiple sediment cores. The burial rate ranged between 5 - 25 g C m-2 yr-1, which is of the same magnitude as lake C emissions. I show that the emission:burial ratio is about ten times higher in boreal compared to in subarctic-arctic lakes. These results indicate that the balance between lakes C emission and burial is both directly and indirectly dependent on climate. This process will likely result in a future increase of C emissions from high-latitude lakes, while the C burial capacity of these same lakes sediments weaken.

Étude de l’orientation cardinale sud dans les sépultures mayas de la Période Classique

Lessard, Sandrine 12 1900 (has links)
Ce mémoire porte sur l’étude de l’orientation des sépultures mayas de la Période Classique (250 - 900/1000 de notre ère). Il s’agit d’une recherche visant à comprendre le choix d’une orientation sud des défunts dans la vallée du Belize et ses environs. L’intérêt porté à cette région vient du fait que l’orientation sud des défunts est un phénomène que l’on retrouve rarement sur le territoire maya, sauf à cet endroit. Alors que la présence de la cardinalité en lien avec la cosmovision maya est attestée dans l’architecture, le plan des sites, la forme et la fonction des divinités, dans l’agriculture, etc., il est plutôt rare qu’elle soit analysée dans les études du traitement funéraire. Ainsi, le but de cette recherche est de saisir l’ampleur de la pratique de l’orientation sud des défunts sur le territoire maya, de comprendre son origine et sa ou ses possible(s) signification(s). Les données des sépultures de la Période Classique de cinq sites de la vallée du Belize (Baking Pot, Barton Ramie, Blackman Eddy, Cahal Pech et Xunantunich), de quatre sites du Plateau Vaca (Minanha, Pacbitun, Mountain Cow et Caracol) et de trois sites situés à l’ouest (Holmul) et au nord (San José et Altun Ha) de ces deux régions sont compilées. Les résultats révèlent que le coeur de cette pratique se trouve dans la vallée du Belize, bien qu’une orientation sud des défunts ait été retrouvée partout. Cette pratique semble apparaitre à la fin de la Période Préclassique et les analyses ne révèlent pas de lien entre l’orientation sud et certaines variables (âge, sexe, position du défunt). Finalement, on arrive à la conclusion qu’il est possible que cette orientation sud des défunts soit en lien avec le passage des défunts dans l’inframonde et que cela forme un choix culturel local en lien avec le statut et l’identité du défunt. / This thesis focuses on the study of the orientation of Classic Maya burials (AD 250 - 900/1000). The research is directed towards the understanding of the presence of the south orientation of burials in the Belize Valley and its surroundings. While the presence of the cardinality of the Mayan worldview is established as reflected in the architecture, settlement patterns, form and function of divine agents, agriculture, etc., it is rarely analyzed in funerary treatment studies. Thus, the aim of this research is to understand the extent of the practice of the south orientation of the deceased on the Mayan territory, to understand its origin, and its possible signification(s). Data from the Classic burials of five Belize Valley sites (Baking Pot, Barton Ramie, Blackman Eddy, Cahal Pech, and Xunantunich), four Vaca Plateau sites (Minanha, Pacbitun, Mountain Cow, and Caracol), and three sites located west (Holmul) and north (San José and Altun Ha) of the two previous regions have been compiled. The results reveal that the heart of this practice lies in the Belize Valley, although a south orientation of the deceased was found everywhere. This practice seems to appear at the end of the Preclassic Period and analysis revealed no link between south orientation and certain variables (age, sex, position of the deceased). Finally, it was found that it is possible that south orientation of the deceased is connected with the passage of the deceased in the underworld, and that it is a local choice in connection with the status and the identity of the deceased.

Etruscan rock-cut tombs and 3D modeling

Votroubeková, Tatiana January 2015 (has links)
This thesis examines Etruscan rock-cut tombs that are characteristic for inland southern Etruria and are dated from second quarter of the 6th century BC to the end of 3rd and beginning of the 2nd century BC. Thesis is focused on the architecture of the tombs, their typology, decoration, iconography and their architectural evolution. Main sites in Archaic period are necropoleis in San Giuliano, Blera, Tuscania and for Hellenistic period necropoleis in Norchia, Sovana and Castel d'Asso. Second part of thesis examines the potential of 3D recording, analysis, virtual reconstruction and virtual anastylosis for the study of the tomb façades through the case studies of the "Tomb of the Siren" from necropolis of Sovana and the "Doric Tombs" from necropolis of Norchia. Keywords Etruscans, Etruscan, rock-cut, rupestral, façade, necropolis, 3D modeling, multi-image photogrammetry, virtual reconstruction, virtual anastylosis

Přechodové rituály jako téma v učebnicích dějepisu / Rites of passage as a theme in the history textbooks

Geyerová, Simona January 2015 (has links)
The intention of the Diploma thesis Rites of passage as a theme in the history textbooks is analyze the history textbooks of upper primary school in terms of rites of passage. This practical part is preceded by general introduction to the issue of rituals and rites of passage. The following is a discussion of selected rites of passage, which are weddings and funerals. Selected rites of passage determine the direction which is going analysis itself textbooks. In general I am interested in themes of weddings, funerals and all other facts that are associated with the issue in analyzing textbooks. Then I find out, how and what extent selected rites of passage are presented to pupils. So that pupils gain the most information from the particular way in view of the rites of passage, I deal also possibilities to enrich a certain representation of ritual. The conclusion summarizes the main reasons for the changes of rites of passage that appear in the history books for upper primary school. KEYWORDS ritual, rite of passage, textbook, funeral, grave, burial ground, wedding, wedding ceremony
