Characterization and Joining of an Historical Ferrous Tie-Rod

A ferrous tie rod, which was retrieved from a 17^th century masonry building, has been examined. The chemical composition and the microstructure of the tie-rod are consistent with the technology of the time.

The tie-rod was successfully welded to modern steel profiles, by means of gas metal arc welding, in order to verify if this method could be applied for restoration works. Threading tests were also successfully performed, for the same purpose.

Both the original tie-rod, and the welded specimens were thoroughly characterized with both metallurgical and mechanical methods; moreover, full-scale tensile tests were performed on both welded and threaded samples.     

How much did a Swedish Schoolhouse Cost to Build? Rewriting the history of 19th-century rural schoolhouses

How much did the 19^th-century rural schoolhouse cost to build? On the basis of a study of schoolhouse building in the Sundsvall region in the period 1842–1900, this article shows how the cost of school buildings increased over time, both overall and by schoolhouse, largely because of the marginalization of cheaper and simpler redevelopment projects, as well as the construction of a number of more expensive schoolhouses. Through the use of extensive source material, preserved from the building of 66 schoolhouses, a more detailed analysis of these developments has demonstrated differences in price levels between purchased schoolhouses, redevelopments of existing buildings and new building projects, and buildings intended for different types of schools. Insights are also given into labour and material costs. In addition to establishing basic facts about a main feature of the expanding system of mass education, this study thus makes a reinterpretation of the 19^th-century rural schoolhouse which emphasizes new patterns of development and fundamental distinctions, presenting schoolhouses as a social and economic issue, rather than an architectural or pedagogical concern. Instead of being described as rather simple buildings, in comparison with the major buildings in the cities, schoolhouses thus appear as a major item of expenditure for local government.     

BUILDING AN IDENTITY: ARISTOCRATIC LANDSCAPE AND CONSPICUOUS CONSUMPTION AT THE 16TH‐CENTURY BISHOP'S PALACE IN ODENSE

In the 16^th century, establishing and maintaining one's status and position in society was an important social factor and motivator. This article examines to what extent such efforts can be deduced from archaeological material. The subject is the 16^th‐century bishop's palace in Odense, Denmark. This case study has been encouraged by the unprecedented large‐scale archaeological excavations that have taken place in the Odense city centre in recent years. The new archaeological data allows for a contextual analysis in which the finds and structures are considered as evidence for negotiated identity expressed through materiality. The main conclusion is that a unique socioeconomic identity is expressed in the building structure, while evidence from the portable objects is more ambiguous.     

VIEH,LAUB UND VERSAMMLUNGSPLATZ: SOZIALE ORGANISATION IN DER BRONZEZEIT,BEISPIEL BRUNDE/EGELUND

In 2009, a site containing multiple so‐called cooking pits with fire‐cracked stones was excavated at Egelund near Rise, four kilometers northwest of Aabenraa, southern Denmark (Site Id HAM 4791 Egelund III) (Note/Anmk. 1). The excavation has led to a larger research project focusing on the material remains from the Bronze Age within a 30 km radius of the site (Fig. 1). The ancient community of Rise is characterised by a wide range of material evidence that has been excavated and well documented during the last twenty years. It was therefore considered as relevant to carry out a comprehensive study of the entire archaeological collection from this area and to include as many different sources as possible (Note/Anmk. 2). The article presents an integrative approach that combines different find categories from dwelling remains to pottery production in an attempt to provide a proper interpretive background for the distribution of cooking pits in the Rise micro‐region. One of the most significant results is the demonstration of continuous use of a gathering place attested at Egelund during a period of 1000 years, from the 15^th to 5^th century BC. Different communities combined their resources and effectuated such projects as the building of barrows or dwellings.     

Rare Types of Trephination from Hungary Shed New Light on Possible Cross‐cultural Connections in the Carpathian Basin

Symbolic or incomplete trephinations are very common in Hungary in 9^th–11^thcentury AD skeletal series connected to early Hungarians, although they also occur in the preceding Avar Age (6^th–9^th c. AD) material. During the compilation of a database of regional cranial modification data, the authors found rare almond‐shaped symbolic trephinations in both periods, while these had formerly only been reported in Early Hungarian series. In this study, the new almond‐shaped lesions are described along with other symbolic trephinations of 14 newly found skulls from the 8^th–11^thcenturies AD in the Southern Great Plain of Hungary. The authors review the research of the phenomenon. The new findings may strengthen the theory of direct and very close cultural connections of these two ethnic groups, adding a new aspect to the debate over the origin and relationship of Late Avar (late 7^th–early 9^th c. AD) and Early Hungarian (9^th–11^th c. AD) populations. Copyright © 2013 John Wiley & Sons, Ltd.     

Application of Shape Memory Alloys in Historical Constructions

A device prototype, based on the superelastic properties of Shape Memory Alloys (SMAs), is proposed to enhance the thermal and seismic behavior of steel tie-rods. First, the thermal behavior of steel tie-rods with and without SMAs is presented based on the results of extensive experimental tests in thermal room. Next, the seismic performances of the proposed SMA system are discussed based on the results of a series of shaking table tests on a 1:4-scale timber roof truss model. In this article, the functioning principles of the proposed SMA-based device prototype are illustrated and the main aspects related to its implementation in practice are discussed in detail. Finally, a recent example of application of the proposed technology to a historic single-aisle church, realized in the 13th century in Brindisi (southern Italy), and equipped with inadequate and deteriorated steel tied rods, is shown.     

The Excavations at Tel 'Eton (2006–2009): A Preliminary Report

Abstract

Tel 'Eton, commonly identified with biblical 'Eglon, is a large site in the trough valley in the southeastern Shephelah. Since the summer of 2006, Bar-Ilan University has been carrying out a large-scale exploration project at the site and its surroundings. The excavations were preceded by a detailed mapping of the site, which was subsequently divided into 39 sub-units. This was followed by survey and shovel tests in each of those units, and by full-scale excavations in four excavation areas. It appears that the site was first settled in the Early Bronze Age, and again in the Middle Bronze Age to the late Iron Age (8^th century BCE). Following a settlement gap in the 7^th–5^th centuries BCE, the site was resettled for a short period in the late Persian or early Hellenistic period. Among the major finds is a thick Assyrian destruction layer (8^th century BCE), which sealed many houses with their content, including many pottery vessels, metal artifacts, and botanical material (some still within the vessels), and many additional finds. The present article summarizes the results of the explorations of the site in 2006–2009.     

Neonatal Mortality,Young Calf Slaughter and Milk Production during the Early Neolithic of North Western Mediterranean

The North‐Western Mediterranean witnessed a rapid expansion of farmers and their livestock during the Early Neolithic period. Depending on the region, cattle played a more or less important role in these communities; however how these animals were exploited for their milk is not clear. Here we investigate calf mortality to determine indirectly whether cattle dairying was practised by Early Neolithic stock herders. Age‐at‐death (AtD) frequencies for calves from two sites: Trasano (Italy, Impressa culture: 7–6^th millennium BC) and La Draga (Spain, Cardial culture: 6^th millennium BC) were estimated from dental eruption and development stages, and measurements of un‐fused post‐cranial material. Adult age classes are well represented in the dental AtD frequencies and were interpreted as the result of the slaughter of prime beef and retired lactating females. For calves aged less than 12 months, there was no statistical difference in the AtD frequencies based on dental and post‐cranial material indicating that the data is a good representation of the mortality patterns of calves, either natural or deliberate. At both sites there was a strong mortality peak at 3–6 months in all AtD profiles. At La Draga, this peak was clearly differentiated from a peak at 0–1 month, which can be interpreted neonatal mortality possible a consequence of the birthing season coinciding with the end of winter during more humid climatic conditions that at present. The deliberate slaughter peak around 3–6 months is discussed, and we propose that stock herders controlled the mortality of infant classes, possibly in response to variable external environment pressures while maintaining animal productivity.

THE MEDIEVAL URBAN CHURCHYARD AS A MEETING PLACE: A CASE STUDY OF FUNCTION AND ORGANISATION OF THE CHURCHYARD OF ST. CLEMENS IN COPENHAGEN

The article presents the results of a study based on activity analysis of a medieval churchyard of St. Clemens in the urban setting of Copenhagen. The churchyard was in function from the 11^th to 16^th century revealing changes in layout and burial rites over time. A glimpse of the symbolic life of the medieval Copenhageners is also exposed and analysed. Moreover, the study of the churchyard reveals activities of a more secular nature and presents some of the activities that must have been part of everyday life in the medieval town. Thus, the churchyard has not only been an arena for meetings between the living and the dead but also a location for experiencing the urban life burgeoning outside the churchyard. For comparison, a recently discovered contemporaneous churchyard at Rådhuspladsen is also discussed.     

Soils and Earthen Building Materials Used for the Buddhist Temple Complex

This article presents a comprehensive study of the local soils and historic earthen building materials used in Nako temple complex in Western Himalayas. On-site and laboratory investigations followed a holistic approach to characterize materials and identify historic manufacturing formulas. The interdisciplinary and novel methodology used for analysis of the earthen building materials combine geological, chemical, mineralogical, geotechnical, and mechanical approach. The results presented in this article enable a better understanding of material culture and advance the study of damage and decay processes found in the temple buildings. In addition, a suitable conservation and preservation strategy is presented.     

Free and Happy Bonds: Loving v. Virginia's Nineteenth-Century Precedent on Marriage and the Pursuit of Happiness

Loving v. Virginia declares that marriage contributes to the pursuit of happiness. It supports this claim by citing 19^th century precedent, precedent which itself drew upon a longstanding view of marriage and happiness's pursuit. This article examines that view in state and federal opinions from the decades surrounding 14^th Amendment ratification. The courts saw marriage as fulfilling the human need for community, thereby aiding in the private happiness of those marrying and the public happiness of the political society. Marriage supported private happiness by forming a bond that provided for physical, material, and emotional needs. Courts sought to aid these goals while also protecting spouses' rights. Marriage supported public happiness through creating and educating future citizens as well as cultivating virtuous habits among those married—goals which the courts also sought to protect. The article concludes by discussing the continuity and discontinuity between these 19^th century cases, Loving, and Obergefell.     

Memories of an Imperial City: Race,Gender, and Birmingham,Alabama

September 15, 2013, marked the 50^th anniversary of the 16^th Street Baptist Church bombing in Birmingham, Alabama, USA. The bombing remains one of the most infamous events in the history of white supremacist violence in the United States. While conventional accounts of the event and its aftermath often consider the legal restructuring of the US state following the passage of subsequent Civil Rights legislation, little has been written about the transnational significance of Birmingham in shaping the character of US power abroad. This article argues that memorialisation and cultural architecture of Birmingham represent a significant crucible forging a particular style of liberal empire. Tracing a cultural genealogy of Birmingham through the writings of former Secretary of State and National Security Advisor Condoleezza Rice and famed scholar-activist Angela Davis, I demonstrate how Birmingham, as a site of historic black struggle, has been remembered alongside the place-making of empire.     

Visualisierungen in der deutschen Geographie des 19. Jahrhunderts. Die Beispiele Robert Schlagintweit und Hans Meyer

Visualization in 19^th‐century German geography: Robert Schlagintweit and Hans Meyer as examples. – Visual representations of nature formed an essential part of 19^th‐century earth sciences. In particular, colonial photography – as a visual source, and as an instrument of the construction of national identities – serves essential research interests of current history and social sciences. The present paper is a case study on the role and function of photography in German geography of the 19^th and early 20^th centuries. It focuses on the work of the Munich geographer Robert Schlagintweit (1833–1885) and the Leipzig colonial geographer Hans Meyer (1858–1929); the early history of photography in India and the function of images in the geographical exploration of overseas territories are discussed. Although there is nearly half a century between the work of R. Schlagintweit and H. Meyer, their photography shows remarkable parallels. The ideas of both on the practice of visualization are rooted in pedagogic and didactic concepts as well as in popular science. For both geographers photography was essentially a technical help, which often needed graphic revisions. And they both preferred photography to depict people and buildings (compared, for instance, to landscapes). Concerning the more comprehensive question of how far their photography transmitted a specific German ‘image of abroad’, it is indicated that such a specific image should have its essential roots in a peculiar visual culture of German earth sciences in the first half of the 19^th century. Thus the paper offers a starting point for further studies discussing the change from a ‘Biedermeier image’ of foreign cultures to a more ‘colonial’ one in 19^th‐century German geography.     

Landscape Archaeology in a Dry-Stream Valley near Tell es-Sâfì/Gath (Israel): Agricultural Terraces and the Origin of Fill Deposits

Abstract

As part of the long-term archaeological project being conducted at Tell e-Sâfi/Gath in the semi-arid foothills of the Judean Mountains, a first order dry stream channel located in a valley east of the main site was surveyed and soil pits excavated in selected locations. A ditch, 10 m in length, was dug perpendicular to one of the agricultural terraces, showing that the small valley is filled with soil to a depth of more than 3 m above bedrock. The fill dates mainly to the Byzantine period (ca. 4^th-7^th cent. CE), according to the ceramic sherds. Three check-dam walls and related terraces were found across the width of the valley. Surprisingly, the base of the check-dam does not go deeper than 50 em into the uppermost part of the fill, well above bedrock or gravel layers, while covering only the upper part of the terrace step. Thus we use the term “floating terrace wall” or “floating check-dams”. Each of the terrace walls is about 0.5 m high and 50 m long. The valley is bound by two slopes: (1) a northeast facing slope characterized by Nari outcrops (a hard calcrete crust in the upper part of the chalk bedrock) and soil pockets, and (2) a southwest facing slope without Nari. The source of most valley fill material is apparently from the slope without Nari. The valley shows comparatively little accumulation during the Iron Age and very much accumulation during the Byzantine period. The main cause seems to be human-made earth movement and terrace building during the Byzantine period, rather than passive erosion and accumulation as a result of general environmental pressure by human activity.     

Charcoal in alluvium of mountain streams in the Bieszczady Mountains (Polish Carpathians) as a carrier of information on the local palaeoenvironment

Fragments of charcoal are present in floodplain alluvium of the San and Strwi?? rivers in the Polish part of the Bieszczady Mountains, Polish East Carpathians. They occur as single clasts or in lenses in the basal part of fine-grained alluvium, together with unburnt wood debris, or in the middle part of the vertical sequence of the floodplain alluvium. 14 samples of charcoal from the upper courses of the San (ca. 50 km) and the Strwi?? (ca. 10 km) were dated with radiocarbon. The obtained dates fall mainly in the 15^th through 19^th century interval; only one sample is markedly older (9^th–10^th century). Taxonomic composition of the charcoal source wood was also studied and compared with that of coeval forests. Correlation of the charcoal age with the history of economic development of the studied region indicates that charcoal is of anthropogenic origin: older charcoal from intense slash-and-burn deforestation, while younger charcoal was produced by local industries.     

Isotopic Evidence for Diet Among Historic Bedouin of Khirbat al‐Mudayna,Jordan

Interpreting the behaviours of nomadic groups from the archaeological record is particularly challenging owing to the ephemeral remains produced by their lifestyle. As such, human burials – even from isolated contexts – provide a wealth of information about these transient groups. Stable carbon and nitrogen isotope analysis of a series of human skeletal remains (n = 22) from isolated burials were utilized to reconstruct the diet of historic (ca. 13^th–19^th century CE) Bedouin from the Khirbat al‐Mudayna vicinity in modern‐day Jordan. Carbon isotope values ranging from −17.7 to −12.5‰ point to variable dietary contributions from both C₃‐ and C₄‐based foods, while corresponding faunal δ¹³C ratios ( = −19.0 ± 1.7‰, 1σ) exhibit depletion in ¹³C characteristic of a predominantly C₃ diet. While mean human δ¹⁵N values ( = 12.7 ± 1.9‰, 1σ) may suggest that the majority of protein consumed by these nomads came from animal and not plant sources, elevated δ¹⁵N ratios in some fauna may be indicative of ¹⁵N‐enriched soils as reported in some arid desert environments. Considerable variability in both δ¹³C and δ¹⁵N values also points to differences in individual life histories and subsistence economies over time. Despite a lack of temporal cohesion, these data illustrate the information that can be gleaned from the isolated interments of nomadic or semi‐nomadic individuals.

Chemical analysis of white porcelains from the Ding Kiln site, Hebei Province, China

The Ding kilns were some of the most famous early kilns of medieval China, producing huge quantities of white and cream-white porcelains of outstanding technical and aesthetic quality. Since 1949 they have been excavated three times, in 1965, in 1987, and in 2009 respectively. In this latest study 69 white porcelain sherds from assured contexts and from the 2009 excavations were analyzed using laser ablation techniques (ICP-AES). The samples date from Five Dynasties, Northern Song and Jin Dynasties respectively (early 10^th to early 13^th C CE). The results show that Ding wares of different times show different characteristics that can be demonstrated through chemical composition. During the early phase of production the Ding ware bodies consisted largely of high firing kaolinitic clays with predominantly calcareous materials as fluxes. After the early Northern Song Dynasty, some calcareous material was replaced by a more potassic material. The compositions of the glazes show a parallel evolution to the bodies. However, because the glazes are very low in titania it seems unlikely that the main clay ingredients of the bodies could have been used in the glaze recipes. For much of the kiln site’s history the glazes appear to have been made mainly from the same siliceous flux-rich materials that had been blended with the main body-clays used to make the Ding ware porcelains, plus some extra calcareous material. The P₂O₅ contents of the glazes suggest that wood ash may have been one source of CaO in the glaze recipes.     

A Large‐Scale Palaeopathological Study of Hip Fractures from Post‐Medieval Urban England

Hip fractures have high incidence rates in many current groups and are associated with high morbidity, mortality, and considerable expenditure. Although hip fractures associated with significant traumatic events can occur at any age, many hip fractures occur in older adults. To date, few hip fractures have been reported from archaeological skeletal material, and a number of hypotheses have been suggested for this. This research presents a comprehensive assessment of hip fractures in archaeological bone; 1597 adult (18+ years) skeletons from eight urban post‐medieval sites from England dating from the 18^th and 19^th centuries were recorded, and contemporary medical texts reviewed. This adult sample included 834 males and 652 females as well as 11 persons of undetermined sex. Ways of classifying and describing fractures in the clinical literature were reviewed and a methodology applicable to paleopathology determined. Of this sample, 15 (0.94%) had fractures in the femoral neck or intertrochanteric area: nine males, four females, and two individuals of undetermined sex. The numbers of fractures in males were interesting and most likely represent examples of accidental trauma as well as osteoporosis‐related fractures, the latter receiving growing awareness in recent clinical literature. Overall there was an age‐related trend with more individuals aged 50+ years with fractures than in other age categories. Underlying osteoporosis was potentially a complicating factor in five individuals and was likely associated with a vitamin D deficiency osteomalacia and a metastatic neoplastic condition in a further two cases. Fractures occurring close to the time of death and healed fractures were observed, indicating that the risk of mortality following this trauma was not consistent across this 18^th and 19^th century sample. Skeletal and historical evidence presented in this study indicate that the impact of hip fracture injuries varied, with survival likely linked to the fracture type.

On the Fourteenth Amendment: A Textual Analysis

Abstract

The most significant and lasting results of the Civil War were the 13^th Amendment, abolishing slavery in the US, and the 14^th Amendment, protecting certain privileges, immunities, and rights of citizens and persons in the US. The meaning of the 123^th amendment has been, for the most part clear and uncontroversial. The same cannot be said for the 14^th Amendment. The language of the 14^th is much more complex than that of the 13^th and the interpretation of the meaning of the Amendment has been very controversial since the very first Supreme Court cast attempting to construe it. My article attempts to show that despite that history of controversy and uncertainty of meaning the 14^th amendment is a model of clear constitutional draftsmanship and translucence of meaning.
