Abstract:
During the Imperial Roman period, thousands of theatres were built. The theatres have three principal elements: the scene building (actor position), the orchestra and the cavea (spectator seating). The theatres were built without a roof, so they were open-air spaces. The theatres were abandoned afterward the barbarian invasions, and during the Middle Ages, homes were built inside the cavea. The theatres were rediscovered during the Renaissance period. Today, ancient theatres are the center of cultural events and are used for various kinds of shows. This work discussed the acoustics of the Roman theatre of Benevento, which was built during the Imperial Age. The theatre was destroyed after the barbaric invasion and it was rebuilt in the first half of the 1900s. The theatre was opened in 1957, and today it is the center of social and cultural activities. Acoustic measurements were carried out according to ISO 3382 standard, placing an omnidirectional sound source on the scene building and in the orchestra, with the measurement microphones along three directions in the cavea. The acoustic characteristics in various seating areas of the cavea were evaluated. Therefore, it possible to understand in which sectors of the theatre the acoustic characteristics are optimal for different types of theatrical performances.

Abstract:
The long history of excavation of the theatre at Stobi has yielded much information about the chronology, construction and usage of the building, as well as about post-theatre occupation of the area. Archaeological investigations in the 1970s and new excavations which began in 2009 have shown that construction of the theatre was initiated at the end of the 1st c. A.D. on the model of a western Roman theatre, as a building with a semicircular cavea and a scene building with an indented scaenae frons similar to the Augusta Emerita (Mérida) type. Construction was then interrupted for a certain period for unknown reasons. In the first half of the 2nd c. A.D. it was finished according to a different concept, one that resembled the Roman theatres of Asia Minor. In its final appearance the building included a cavea that exceeds a semicircle, a high podium around the orchestra, open parodoi, and a rectilinear scaenae frons (figs. 1-2); in its final form it incorporated the cavea from the first phase, whereas the scene building was completely remodeled.

Abstract:
Carbonate reservoirs are mainly fractured-caved reservoirs with very well-developed dissolved pores, fractures, and caves. They have strong heterogeneity with various types of reservoir pore spaces. Using seismic inversion and reservoir static characterization, the result shows that the fractured-caved carbonate rocks in China are mainly caves with poor connectivity and complex oil-water distribution. Large-scale dissolved caves are mostly discrete and isolated, while the fractures are complex and various. The fracture features are observed either as a single large fractures or as a local fracture network. The characteristics of fluid flow in fracture-caved reservoirs vary as a result of the different combinations of fractures and caves. Currently, the static characterization technology of fractured-caved reservoirs is influenced by the limited resolution of seismic data, leading to large interpretation errors. In contrast, the dynamic method is a more reliable and effective method to determine reservoir parameters. However, traditional seepage equations cannot accurately characterize the flow pattern of fractured-caved carbonate reservoirs. In the case of a single large-scale dissolved fractured-caved reservoir, oil wells are usually connected to large caves through large fractures or directly drilled into large dissolved caves. In this study, the large-scale dissolved caved reservoir is simplified into two cases: (1) a single-cave and single-fracture series model composed of a single-cave and a single-fracture and (2) a composite model of dissolved caves and surrounding fracture networks. Note that the flow in a large cave is considered as free flow due to its large scale. The flow in a large fracture connected to the cave is considered as flow through porous media, and the flow in the reservoir surrounding the fracture network is considered as multiple-porosity model seepage flow. The corresponding seepage-free flow coupling mathematical model of different fractured-caved reservoirs has been established on this basis. We also obtained the rate transient analysis type curves of the oil well, conducted sensitivity analysis of each parameter, constructed the corresponding rate transient analysis curves, analyzed sensitivities of each parameter, and finally designed a dynamic evaluation method of well and reservoir parameters for different types of fractured-caved carbonate reservoirs. This study extensively applies this method in the Halahatang Oilfield of China and evaluates parameters such as reservoir reserves and physical properties to provide rational guidance for developing fractured-caved carbonate reservoirs.

Abstract:
Excavations at the Sparta theatre were resumed in 1992: the objective was to survey it and clarify its history. Nine trenches were opened and a catalogue of architectural blocks compiled. A trench in the sw orchestra revealed two staircases; while the seats of honour, the walkway behind, and two or three rows of benches above are preserved, the remainder of the theatre was severely damaged in the 9th–13th centuries. The diazoma's foundations were revealed; below it were ten radial staircases, above seventeen. The lower cavea had thirty-one rows, the upper nineteen. At the top, rows 17–19 rested on concrete over an inner radial wall of concrete-bonded stones; there are traces of a Doric colonnade around the walkway here. The upper cavea yielded pottery suggesting an initial construction under Eurykles (c.30–20 BC); no certain evidence of an earlier theatre has been found. The stage building's architecture suggests Flavian and Severan reconstructions and later repairs. The site's use as a theatre ended c. AD 400, but finds indicate early Byzantine continuity and three later occupation phases (9th–13th centuries). Sculptures found include a statuette of Apollo or Dionysos, an Antonine female portrait (priestess?), and an important late Roman male portrait head.

Abstract:
Over the last decade, a Herodian facility for chariot racing has been excavated at Caesarea Maritima by two different teams. A team of the Israel Antiquities Authority (IAA) under my direction has been responsible for excavating the cavea and most of the arena (fig. I), while the Combined Caesarea Expedition under J. Patrich has excavated the carceres and a small portion of the arena. Patrich recently published (JRA 14, 269-83) the archaeological evidence for the carceres, but some of his conclusions about how the facility as a whole operated, especially those relating to the larger area excavated by the IAA, are misleading, and I would like to discuss and correct them.Patrich calls the stone-built facility for chariot racing a “hippodrome/stadium”, although that is not a commonly accepted term among the types of ancient entertainment buildings. The sources and archaeological evidence make it clear that an entertainment building belonging to a particular building type could house a wider variety of performances than just those chiefly associated with that type. Thus, in addition to chariot races, a circus could legitimately hold athletic contests typical of the stadium in front of the longitudinal sections of the cavea, and it might even hold performances typical of theatre and amphitheatre in its semicircular end opposite the start.

Abstract:
The theatre of Sagalassos lies to the north-east of the city, high up the mountain. It is undoubtedly one of the best preserved monuments on the site (Pl. XXV (a)), although some parts of it have collapsed as a result of successive earthquakes. The southwestern part of the cavea, which was built on artificial substructures, and the free-standing stage building are particularly badly damaged, but even there the blocks still lie scattered in the vicinity and very few pieces are missing. Despite this, opinion concerning the reconstruction of the scaenae frons, and even some details of the cavea, differs widely (see below).During the 1991 season at Sagalassos we started a study of the building and its decoration. Even though this has not been completed, some results have already arisen, which I would like to discuss in this article. A close examination of the fallen blocks of the stage building, gave clear indications for the reconstruction of the scaenae frons. Their decoration supplies clues for the dating of the monument. New study of the theatre façade allows a one-stage reconstruction, as proposed originally by G. Niemann in Ch. Lanckoronski's work concerning the cities of Pisidia and not the two storeys, proposed by D. de Bernardi Ferrero, and a date in the last quarter of the second century A.D.

Abstract:
Landslides are serious geological disasters in loess areas. In order to study the effect of the filling caves in the edge of loess tableland on loess slope stability, the slope stability of sliding from the caves was calculated in irrigation when caves were filled with compacted soil, lime soil, lime-ash soil and non-filled. The results show when caves are filled with lime soil the slope stability is the highest. The effects of variability of the physical and mechanical property indexes of caver filler on loess slope stability were researched further. The results show that (1) the variation coefficients of unit weigh and the shear strength indexes of cave filler lime soil have small effect on the average value of safety reserve, but have big effect on the standard deviation of safety reserve, which explains that the design risks increase while the variation coefficient increasing. (2) with the increase of variation coefficients of unit weigh and the shear strength indexes of cave filler the failure probability increases. Especially when variation coefficient is bigger than 0.3, the failure probability of loess slope is very sensitive to variation coefficient. (3) the effect of correlation coefficient among unit weight and the shear strength indexes of cave filler on failure probability increases with the variation coefficient increasing. It is very important to guarantee filling project. Good quality of filling construction will decrease the variability of cave filler, heighten the stability of loess slope, and decrease the occurrence of loess disasters.

Abstract:
Le « théâtre gallo-romain » a toujours été un sujet sensible parmi les archéologues. Depuis la théorie du « théâtre-amphithéâtre » jusqu’au renouveau de l’étude de ces édifices de spectacle par Françoise Dumasy, les théâtres de Gaule romaine ont toujours été étudiés en fonction du modèle « latin » proposé par Vitruve dans le de Architectura. Plusieurs raisons ont souvent été évoquées pour expliquer les formes particulières des théâtres dits « gallo-romains ». L’objectif de cette thèse n’est pas de proposer une définition définitive de ce qu’était le théâtre en Gaule romaine, de fait trop peu sont encore fouillés pour proposer une synthèse générale. Toutefois, à travers l’étude régionale des théâtres du nord-ouest des Gaules, il est possible d’entrevoir l’un des instants les plus intéressants de l’adaptation du théâtre romain dans ce qui a souvent été considéré comme une région éloignée de l’Empire
The « Gallo-roman theatre » has always been a sensitive subject among french archaeologists. Since Albert Grenier’s theory on the « theatre-amphitheatre » to Françoise Dumasy and the renewal of studies about roman entertainement buildings, roman theatres in Gaul have always been considered as different buildings compared to the classical theater pattern suggested by Vitruvius in his de Architectura. Many different reasons were frequently mentioned to explain the particular forms of « Gallo-roman theatres ». The intended purpose of this PhD is not to give a definitive definition of what roman theatres in Gaul could be -in fact, too few of them were excavated. Nevertheless, it is possible trought a regional study of roman theatres in north-western Gaul to have a glimpse of one of the most interesting moments of the adaptation of a roman theater in what has been considered as a remote region of the roman empire

Abstract:
The Waitomo Caves attract approximately 500 000 tourists each year. A requirement of tourist cave management is that the partial pressure of carbon dioxide (PCO₂) is kept below levels that are: hazardous to the health of visitors, hazardous to the glowworms and other natural inhabitants, or potentially corrosive to speleothems. For the Glowworm Cave at Waitomo, the maximum permissible PCO₂ level is 2400 ppm. When exceeded, the tourist operators are required to close the cave. Ten years of monitoring data at the Glowworm Cave was analysed. Most of the variation in PCO₂ could be attributed to CO₂ respired by tourists, and the mixing of cave air with lower PCO₂ outside air. Occasionally, there were periods with high PCO₂ levels while the cave was closed to tourists. The main objective of this study was to investigate the potential role of the Waitomo Stream in contributing CO₂ to the Glowworm Cave atmosphere. Analysis of ten years of Glowworm Cave monitoring data showed that the 2400 ppm PCO₂ limit was, on average, exceeded five times each year, with a total of 48 events between 1998 and 2007. Of the PCO₂ limit exceedences, approximately 31% of events were largely driven by high tourist numbers; 27% of PCO₂ limit exceedences were mainly driven by increased discharge, rainfall, and/or a low temperature gradient between the cave and outside air, whilst 29% of the PCO₂ limit exceedences were due to a combination of tourists and increased discharge, rainfall, and/or a low temperature gradient. The remaining 13% of exceedences were unexplained by tourists or the factors investigated. It may be that the unexplained exceedences were due to the night time closure of the cave door, restricting air exchange. The PCO₂ of the Waitomo Stream was measured by equilibrating air with the streamwater within a closed loop. The air was passed continuously through an infrared gas analyser (IRGA). The streamwater PCO₂ typically ranged between 600 - 1200 ppm. Fluctuations in the PCO₂ of the Waitomo Stream coincided with PCO₂ fluctuations in the Glowworm Cave air, and under most conditions, the stream probably acted as a sink for cave air CO₂. However, following rainfall events, the stream PCO₂ increased, exceeding cave air PCO₂, thus acting as a source of CO₂ to the cave air. High stream PCO₂ often occurred at times when air flow through the cave was restricted, e.g. when the temperature gradient between the cave air and outside air was low, or stream levels were high, thus limiting air movement. The combination of high stream PCO₂ and a low temperature gradient increased the likelihood of high cave air PCO₂. Dripwater was measured to determine whether an increase in dripwater PCO₂ occurred in response to rainfall events. When rainfall events resulted in increased discharge, the dripwater PCO₂ sometimes increased (occasionally exceeding 5000 ppm), however the pattern was not consistent. The chemistry of the Waitomo and Okohua (Ruakuri) Streams was monitored with daily samples collected and analysed for major ions: HCO₃ -, Ca²⁺, Na⁺ and Mg²⁺, and δ¹³C stable isotope. The HCO₃ -, Ca²⁺, Na⁺ and Mg²⁺ concentrations in the streamwater decreased with increased discharge, presumably due to dilution. Increased discharge following rainfall events correlated with increasing PCO₂ in the Waitomo Stream, suggesting that soil atmosphere CO₂ dissolved in soil waters, and carried to the stream by saturated flow, was responsible for the streamwater PCO₂ increase. Ca in the stream showed both an increase and a decrease with respect to rainfall. Increased Ca in the stream occurred at times when the discharged waters were coming from the phreatic zone, and thus sufficient time had lapsed for CO₂ in the discharge waters to react with the limestone (carbonate dissolution reaction). Decreased Ca occurred when the infiltration and percolation of rainwater was rapid, and thus the streamwater was characterised by a higher PCO₂ and a lower Ca concentration, as insufficient time had lapsed for the discharge waters to equilibrate with the limestone. Increased negativity in the δ¹³C of the Waitomo and Ruakuri Streams coincided with increased discharge. During summer low flow, the δ¹³C of Waitomo Stream waters was -11.3‰, whereas during high stream discharge events, the δ¹³C dropped to -12 - -14‰. The δ¹³C of limestone is 0‰, the atmosphere is -7‰, and the soil atmosphere is reported to be about -24‰, thus the decrease in δ¹³C during high flow events supports the contention that soil atmosphere CO₂ is a likely source of the increased CO₂ in flood waters.

Full text
Abstract:
Stable isotopes in ice cores drilled in the polar and high-mountain region have been used intensively to reconstruct past climatic changes and atmospheric dynamics. However, no similar studies have been conducted on perennial ice accumulations in caves due to a limited understanding of the links between the external and cave environments, and the way in which the climatic signal can be recorded by the cave ice. In this thesis, we successfully designed and build a research methodology for the reconstruction of past climatic changes based on perennial ice accumulation in caves, using as example the Scarisoara Ice Cave, Romania. The ice block in this cave preserves a large variety of candidate proxies for both past climate and environmental changes, the most significant ones being the stable isotopic composition of the ice (a proxy for air temperature) and pollen remains. The ice block has formed by the successive accumulation of layers formed by the freezing of water accumulated from late summer through mid-autumn precipitation. An original method has been developed for the reconstruction of the stable isotopic composition of water before freezing, and further, of the late summer air temperature. Pollen in the ice has been found to reflect changes in surface vegetation at both local and regional scale. A 22 m long ice core has been extracted from the ice block, and stable isotope analyses were performed at high resolution on its entire length. Twenty-sex radiocarbon ages have been used to derive a precise depth-age model for this core. The stable isotope data covers almost the entire Holocene, between 0.09 and 9.75 ka BP. The first order fluctuation broadly follows the orbitally induced Northern Hemisphere September insolation, with a minimum in the early Holocene, a slow climb towards a maximum at ~5.0 ka, followed by a very slow cooling towards the present, accentuated after ~0.5 ka. Superimposed on the long-term variations a series of rapid cooling events (RCE) are recorde, the most notable ones being at 9.5 ka, 8.2 ka, 7.9 ka, 6 ka, 4.2 ka, 3.2 ka and 0.9 ka. The timing of these RCEs agrees remarkably well with the Holocene rapid climatic changes and the ice rafted debris (IRD) events in the North Atlantic (NA). Our data suggests that the general trends of temperature changes in mainland Europe during the Holocene were governed by changes in solar output. RCEs were synchronous with NA IRD events, the NA climatic signal originating from sea surface temperature changes and being amplified by atmospheric dynamics. The stable isotope data spanning the past 2000 years clearly shows four climatic events over this interval, attributed to the Roman Warm period (RWP), the Dark Ages Cold Period (DACP), Medieval Warm Period (MWP) and the Little Ice Age (LIA). Our data suggests that air temperature was highly variable during the LIA and more stable during the warm MWP and RWP. As ice caves were described in many parts of the world otherwise poorly represented in ice-based paleoclimatology, the results of this study could open a new direction in paleoclimatic research, so that an array of significant paleoclimate data can be developed based on their study.

Abstract:
The importance of ants as elements in cave ecology has been mostly unrecognized. A global list of ant species recorded from caves, compiled from a review of existing literature, is presented. This paper also reviews what is currently known about ants occurring in Arizona ( USA) caves. The diversity and distribution represented in these records suggests ants are relatively common cave visitors (trogloxenes). A general utilization of caves by ants within both temperate and tropical latitudes may be inferred from this combined evidence. Observations of ant behavior in Arizona caves demonstrate a low level and sporadic, but persistent, use of these habitats and their contained resources by individual ant colonies. Documentation of Neivamyrmex sp. preying on cave-inhabiting arthropods is reported here for the first time. Observations of hypogeic army ants in caves suggests they may not penetrate to great vertical depth in search of prey, but can be persistent occupants in relatively shallow, horizontal sections of caves where they may prey on endemic cave animals. First cave records for ten ant species are reported from Arizona caves. These include two species of Neivamyrmex (N. nigrescens Cresson and Neivamyrmex sp.; Formicidae: Dorylinae), four myrmicines (Pheidole portalensis Wilson, Pheidole cf. porcula Wheeler, Solenopsis aurea Wheeler and Stenamma sp. Westwood), one dolichoderine (Forelius keiferi Wheeler) and three formicines (Lasius arizonicus Wheeler, L. sitiens Wilson, and Camponotus sp. Mayr).

Abstract:
 The group cave-temples in Dunguang, Gansu Province of north-western China offer an unparalleled display of grotto art of over a thousand years from the fourth century to the fourteenth century. They represent a microcosm of ancient and medieval civilizations, providing us with enormous opportunities of heritage experience and understanding. However, these grotto treasures are extremely fragile. Over the centuries they have been suffering from serious deterioration and damage due to human and natural causes, and in recent decades the ever-increasing visitor load has posed even greater threat to the murals. The emerging trend of using advanced technology in the preservation and the interpretation of the grotto art offers new possibilities of remote access and interpretation which shall enhance understanding and enjoyment of the cultural treasures. This dissertation sets out to examine such trend of digital interpretation of heritage in off-site scenarios. The research includes a background of the study, the significance of the Dunhuang Caves, the application of new technology, followed by a case study of re-presenting and interpreting one of the Dunhuang caves in Hong Kong.

Abstract:
AbstractThe Romanian karst hosts numerous caves and shelters that over time provided remarkable archaeological and anthropological vestiges. Altogether they show that humans must have entered caves in Romania at least as early as 170,000 years ago. However, ancient human footprints are very rare in the fossil record of East-Central Europe, with only two known locations in the Apuseni Mountains of western Romania. Vârtop Cave site originally preserved three fossil footprints made about 67,800 years ago by a Homo neanderthalensis, whereas Ciur Izbuc Cave was probably home of early H. sapiens that left almost 400 footprints (interspersed with spoors of cave bears), which were indirectly dated to be younger than ~36,500 years.

Abstract:
Tanjungsari is one of the districts in the Gunungsewu Geopark area, Gunungkidul Regency. Since Gunungsewu was declared as a Global Geopark Network area by Unesco, the tourism sector in this area has grown rapidly. Tanjungsari District does not want to be left behind in developing the tourism sector. Therefore it is necessary to trigger the development of tourism. In this district, there are several caves that have the potential to be developed, including Cave Bentar, Cave Cabe, Cave Tritis, Cave Grengseng, and Cave Pakubon, which have their own uniqueness and appeal in terms of morphology, endokarst, and legends. The development of these potential places is expected to be able to improve the economic sector and the welfare of the surrounding community. In order for the caves in Tanjungsari District to be able to compete, the concept of development must be different and not yet developed in other places, namely cave geo-ecotourism. In connection with the above-mentioned matters, research, studies, and feasibility studies are conducted on the potential development of cave geo-ecotourism. The activities carried out include mapping the distribution of geomorphology, geological structures, subsurface conditions, underground water availability using the ERT geoelectric method, and cave tracking. The results of this study are a cave map and an inventory of the potential of the cave.

Abstract:
Abstract The newly discovered the fault-karst carbonate reservoirs in Tarim Basin are formed by large-scale tectonic fault activities and multiple-stage karstification. The ground outcrop, seismic reflection and well logging show that the large caves, vugs, tectonic fractures and matrix coexist in the reservoirs. The fractures interconnecting with caves in series to form vertical beads-on-string structure is the most common pattern. It is found that conventional models are difficult to match the recorded pressure data. To fill this gap, this work summarizes three kinds of patterns for this structure and presents three novel models to estimate formation properties. The physical models of multi-fracture-region multi-cave-region series connection are established by simplifying vertical beads-on-string structure. The corresponding mathematical models are developed, in which the flow in fracture regions obey Darcy's law, while the flow in cave regions obeys free flow. Importantly, the gravity is considered due to the flow along vertical direction. Then typical flow regimes are analyzed and sensitivity analysis is conducted. Our work shows that pressure-derivative curves show similar ‘concave’ characteristic for the cave storage regime and vug/matrix interporosity flow regime. The difference is that the pressure derivative for cave storage regime is unit slope, while this slope is not equal to unity for vug/matrix interporosity flow regime. Therefore, large cave and vug/matrix medium can be distinguished by slope of pressure derivative. More than that, the typical characteristic of vertical beads-on-string structure on type curve is that the cave storage regimes and linear flow regimes alternately appear. This characteristic helps the engineers identify vertical beads-on-string structure. A novel finding is that gravity effect could lead to unit-slope pressure and pressure derivative at late times, which is traditional recognized as the presence of a closed boundary when it may not be the case. Lastly, this methodology is applied to two cases from Shunbei Oilfield in which it is difficult to obtain good fitting quality and interpretation results using traditional methods. Besides conventional properties, the proposed methodology allows us to estimate other properties (e.g., cave height, cave radius), which are not readily obtained from conventional methods.

Abstract:
An approach of machine learning was used to evaluate and predict the production of the heterogeneous carbonate gas reservoirs in the horizontal development wells of the late Precambrian Dengying Formation. The present data set of machine learning consists of gamma ray log, laterolog, high-resolution electrical image logs, and production rate data. The previous data set acquired the conventional openhole logs, including gamma ray log, neutron-density log, sonic log, laterolog, and dipole acoustic log. The challenge in the previous data set was that the training process for machine learning was not convergent. It was most likely that the conventional log responses did not fully correspond to the productivity of the heterogenous carbonate gas reservoirs. Forty-one wells associated with the present data set were used to set up the training sample data set for the machine learning to the productivity prediction of the carbonate gas reservoirs. The data set construction includes log depth shift, calibrated image log creation, classification of reservoir types from core and carbonate reservoir heterogeneity variables extraction from image logs. Core observation and core laboratory analysis indicate that the pore space of the carbonate gas reservoirs mainly consists of vugs, caves, and fractures. However, the vugs and caves are selectively developed and randomly distributed both laterally and vertically. This represents a complex heterogeneous carbonate reservoir in which the vugs and caves are key contributor to the total pore space of the carbonate gas reservoir. The attributes of the vugs and caves can be extracted from the electrical image logs, including connectedness, surface proportion, size, and thickness of vug, and cave zones. Six horizontal development wells were used to validate the machine learning approach. The predicted gas production rates in the four wells separately were 700,000 m3/d, 2,000,000 m3/d, 800,000 m3/d, 300,000 m3/d, 1,100,000 m3/d and 1,180,000 m3/d, and the respective actual gas production rates are 1,019,790 m3/d, 1,820,000 m3/d, 800,000 m3/d, 396,000 m3/d , 1,700,000 m3/d, and 1,411,900 m3/d. The machine learning workflow and approach provided satisfactory results in the six horizontal wells. Subsequently, the electrical image logs have run in the standard logging program in the more than 50 horizontal development wells.
