Efficiency of House-Walls Construction Using Building Ruins

The stage of reconstruction of houses collapsed and damaged by the quake could amount to hundreds of thousands of homes and had to be rebuilt at almost the same time. This will result in a large need for building materials, thus affecting the price of building materials, as well as the demand of builders / construction workers. A major earthquake, such as the one that occurred in Yogyakarta, on May 27, 2006, has resulted in hundreds of thousands of homes severely damaged and collapsed, resulting in a large number of ruins of building materials in the form of masonry walls. The existence of waste material collapses, is a huge potential when reused as a building material through appropriate recycling technology, which can answer two problems at once that meet the needs of building materials and on the other hand can clean up the waste collapse of the building. The construction of walls from wall-crumbling powder (recycled material) is more efficient and effective than conventional wall-making systems when used for mass construction (more than 20 homes) at the same time.

New Evidence of Post-Destruction Reuse in the Main Building of the Palace of Nestor at Pylos

In the past three decades, an Iron Age date for reoccupation of areas surrounding the Palace of Nestor on the Epano Englianos Ridge has become well attested, but the extent and nature of this reoccupation has remained unclear. My reexamination of the Main Building stratigraphy using data recorded in the excavation notebooks has helped define the extent of reoccupation by providing evidence for two phases of temporary reuse. The first phase of reuse, which dates between the final destruction and the early 10th century B.C.E., occurred inside small areas of the Main Building that had not yet collapsed. The second phase occurred on top of and around the Main Building ruins and has a terminus post quem of the early 10th century B.C.E. My reanalysis confirms a more complex site history than originally recognized and bears tremendous implications for looting and other disturbances to the remains.

On the Ability of Geophysical Methods to Image Medieval Turf Buildings in Iceland

AbstractStructures in Iceland were traditionally built of turf, earth and, to a lesser extent, stone. As turf was the primary construction material, the contrast in geophysical parameters between building ruins and surrounding soil is expected to be low. To investigate the extent to which the remains of turf buildings can be detected by geophysical measurements, we applied several geophysical techniques to a known turf ruin in southwestern Iceland. The methods used were magnetics, ground‐penetrating radar (GPR), electromagnetic induction (EMI), electrical resistivity tomography (ERT) and seismic Rayleigh‐wave resonance mapping (RRM). Magnetics identified an accumulation of stones inside and beside the ruin. The in‐phase component of the EMI measurements, which can be related to magnetic susceptibility, showed the same pattern. A very precise image of the stones lining the inside of the former turf walls was generated by GPR. In contrast, EMI conductivity and ERT imaged the actual turf in the walls. Turf walls have lower electrical conductivity compared with the surrounding soil, probably as a result of different porosities. The mapping of Rayleigh wave resonance clearly revealed the outline of the ruin, as indicated by weaker amplitudes compared with the surrounding soil. Overall the results indicate that geophysical methods can be used for subsurface mapping of Icelandic turf structures and that the combined application of the methods maximizes this potential.

Geophysical exploration of castle remains in Barwałd Górny (near Kalwaria Zebrzydowska, Poland) using electrical resistivity tomography (ERT) with assistance of depth of investigation index (DOI) method

Abstract In March of 2014 at ruins of the 14th century castle, situated at the top of Mount Żar in Małopolska region, Poland, geophysical surveys were performed. Surveys were planned to investigate remains of the castle that could remain in the ground. Electrical Resistivity Tomography method was used there. In the paper 4 sections have been presented. During interpretation, as the supporting method, maps of Depth-of-Investigation (DOI) index have been used. Results of the surveys can point out potential remains of the castle walls and ruins of buildings that were situated in the stronghold

The Political Economy of Urban Ruins: Redeveloping Shanghai

AbstractThis essay analyzes the political economy of the urban ruins captured in Greg Girard's photo album Phantom Shanghai. Rather than being marginal, irrelevant or merely objects for nostalgia, the ruins of buildings produced by real estate speculation offer crucial insights into the workings of the urban political economy and reflect wider trends of urban governance. Examining how building ruins come about in the first place and how they are represented in visual media can help us better understand the processes of urbanization and place making, and the central role of destruction in contemporary Chinese urbanism. This essay illustrates this point by analyzing the economic function, political legitimation and cultural significance of demolitions and ruins in urban China.

The features of the earthquake damage patterns of ancient city ruins in the Negev desert, Israel

During the last decades the ruins of Roman-Byzantine cities in the Negev desert of Israel have been the subject of intensive archeoseismic studies. A set of earthquake damage patterns was determined and several large scale earthquakes were identified as having occurred during the 2nd to 7th centuries AD. The ruins of buildings of the small village of Halssa provided a recent study of earthquake damage patterns that evolved quite recently—during the last 110 years.

Autoregressive Modeling of Mobile Radio Propagation Channel in Building Ruins

This paper addresses an autoregressive (AR) spectral estimation technique adapted for modeling of radio propagation channel in collapsed buildings and urban ruins in the frequency domain. Two mobile communication bands, 900 and 1800 MHz, were investigated. Measured channel frequency responses (CFRs) were firstly modeled by an overestimated AR model. In order to reduce this initial model order, the original CFRs were filtered and decimated. The model order was then optimized using the criteria of the signal-to-noise ratio and the maximum excess delay. According to the different debris structures, antenna polarization and RFs, the final model order was from 3 up to 35. The normalized root mean square error of modeled CFRs was between 0.22-0.38 on average. In order to generate a channel simulator, the statistical distribution functions of the simulator parameters, such as the number, arrival time, and complex amplitude of multipath components, were computed from the AR estimated channel impulse responses. Each of these distributions corresponds to the frequency band, antenna polarization, and ruin structure as well.

Geometric Methods of the 1500s for Laying Out the Ionic Volute

Volutes, a distinguishing feature of the Ionic order, are the double curls in the form of spirals on either side of the Ionic capital. In the Renaissance, the Ionic volute was the object of study for architects who were concerned with the development of the new theories of architectural forms. In addition to studies of its proportions, research focused on the search for a sure and elegant method for laying out the volute. The point of departure for the elaborate theories were the ruins of buildings from the classical era and the treatise by Vitruvius. Authors Denise Andrey and Mirko Galli compare and contrast three methods by Sebastiano Serlio, Giuseppe Salviati and by Philandrier for laying out the Ionic volute.

Identifying the site of Raknarr's tomb in the Barthar Saga

The Barthar Saga mentions a Viking tomb on an island in Northern Canada which is connected to the mainland by a reef. Pamiok Island is an island in Northern Canada that is connected to the mainland by a reef, and ruins of buildings and tombs have been found there that have been attributed to the Vikings. It is suggested that Pamiok Island should be accepted as the site of the tomb mentioned in the Barthar Saga until a better candidate is put forth. Key Words: Vikings, Baffin Island, Pamiok Island, Helluland, Barthar Saga, King Ragnarr In the Barthar Saga the tomb of King Raknarr is located on an island in Northern Canada which is connected to the mainland by a long reef that is periodically inundated by the tide. Pamiok Island off the coast of Northern Quebec is just such an island. Pamiok Island is connected to the mainland by a long reef that is periodically inundated by the tide, and, furthermore, graves have been found on the island which have been attributed to the Vikings. Could Pamiok Island be the site of King Raknarr's tomb in the saga? My affirmative answer to this question is based on a combination of two fields of study: literature and archaeology. This cross-disciplinary approach is standard scholarly practice and should be familiar to all students of literature. The two fields of literature and archaeology have both benefited over the years from combined study. It was a knowledge of the legends of the Trojan war, which at the time were thought to be mere myths, that lead Heinrich Schliemann to make his historic discoveries of the ruins of ancient Troy. In England scholars have long been involved in identifying the real sites of places that are mentioned in the legends of King Arthur. Now Glastonbury Tor is recognized as the real basis for many of the Arthurian legends. Many scholars have read the sagas of Lief Erikson's discovery of North America and have tried to identify the real sites that Lief visited. The entire east coast of North America has been subject to the speculations of scholars who, in general, tend to locate the real Vinland in the area of Massachusetts or Newfoundland. Finally, Helge Ingstad's excavations in Newfoundland in the 1960s proved that there was a factual basis to the Norse legends about North America. Thus, identifying the real sites of places mentioned in literature and legend is standard scholarly practice. This approach has also been used with regard to the Barthar Saga. Scholars have attempted to identify the real sites mentioned in the Barthar Saga. The Jon Skaptason/Phillip Pulsiano English language translation of the Barthar Saga contains a map of Snaefellsness in Iceland. Readers of the saga will notice that the first part of the saga is carefully based on real places in Iceland which you can still visit today. Skaptason and Pulsiano did not include a map for the latter portions of the saga, however, which are set in Helluland, because there is no agreement among scholars as to just where exactly Helluland is. Nonetheless, scholars universally agree that Helluland was a real part of the coast of North America. Some scholars argue that it was as far south as Newfoundland. Most scholars think that Helluland was Baffin Island. Still, there is no debate over the fact that the Helluland mentioned in the Barthar Saga was a real place and that it was part of North America. Interestingly enough, one writer, Farley Mowat, has located Helluland on the peninsula of Northern Labrador/Quebec which is adjacent to the Ungava Peninsula where Pamiok Island is located. Mowat bases his identification of Helluland as the peninsula of Northern Labrador/Quebec on two factors. First, Mowat believes that the placed mentioned in the sagas as Greenland's obyggdir is Baffin Island and that therefore Helluland must lie farther to the south. I concur with Mowat, but most scholars do not. Second, Mowat's identification of Helluland with the Northern Labrador/Quebec is based on his reading of the Sigurd Stefansson map of 1570. …

Debris from an Athenian lamp workshop of the Roman period

In 1969 the Fitzwilliam Museum, Cambridge, purchased fifty-five fragments of relief disci from Athenian terracotta lamps of the 3rd and 4th centuries AD. They comprise thirty discus types, and the presence of at least one waster may suggest that they are discards from a kiln site. Recent excavations in the Kerameikos have provided some parallels for the material, especially from the Roman kilns which were built in the ruins of Building Y, to the east of the Sacred Gate.
