Kaolinitic Clay

Using Ptolemaic to late antiquity pottery assemblages from Aswan (ancient Syene) as a case study, we demonstrate the imperative nature of petrographic analyses combined with geological field surveys when investigating ancient potting centres. The combination of archaeological (i.e. abundance of ceramics, vessel shapes etc.), macroscopic and natural-scientific methods allows the reconstruction of the possible extraction areas of clays utilised in Aswan, Upper Egypt. Knowledge of specific clays and their compositional characteristics helps to establish archaeometric reference groups, necessary for differentiating kaolinitic clay sediments of the Aswan area from similar geological environments further down the Nile valley.

Commercially made kaolin is identified as one of the important materials for production of aluminosilicate for catalyst bed support. In this work, an attempt is made to study the potential of local clay for production of aluminosilicate. Three area were identified as kaolin sources in Perak state as they are Trong, Simpang Pulai and Bidor, and labelled as TC, SP and BC, respectively. For preparation of aluminosilicate, formulation using 30% clay and the rest used feldspar (40%) and silica sand (30%). Each batch were formed into ball shapes’ before fired at 1250°C at controlled firing rate of 3°C/min. From the investigation, it is found that only two local clays (CBTC and CBSP) highly potential to be used to produce ceramic ball for catalyst support. In addition, the crushing strength is 100% better than the commercial made product which also have less than 1% water absorption.

Eusebius’s Ecclesiastical History, a seminal late-antique historical narrative, features three periodizations of the church’s past. First, a soteriological periodization divides God’s relationship with humanity at Christ’s Incarnation, an event that Eusebius marks in Book 1 with detailed commentary on the gospels rather than narrative. Second, an ecclesiastical periodization divides pristine, heroic apostolic times from post-apostolic times. The divide between apostolic times and the post-apostolic periods is illustrated through a comparison of History 2.13–17, about Simon Magus, Peter, and Mark, and 6.12, on Serapion of Antioch. And third, an epistemological periodization distinguished earlier times from Eusebius’s lifetime, the latter marked by frequent references to “our time.” Eusebius changed numerous narrative features with his changes of period, including alternating between commentary, diachronic, and synchronic format for different time periods; changing protagonists’ fallibility, individuality, composition of texts, and citation of scripture; and providing notices of episcopal successions and quotation of sources. Moreover, Eusebius’s History changed periods not with the sharp breaks of many modern histories but with gradual transitions. He also underscored key continuities, including God’s intervention in human events and alternation between persecuting and protecting rulers—a continuity within which, contrary to scholarly assumptions, the History never inaugurates a new era with the emergence of Constantine. The case study of Eusebius’s periodization suggests an important limitation of the analytic usefulness of periodizations such as “Late Antiquity” for organizing intellectual history.

<p><em>InfraRed Thermography</em> (IRT) spread quickly during the second half of the 20<sup>th</sup> century in the military, industrial and medical fields. This technique is at present widely used in the building sector to detect structural defects and energy losses. Being a non-destructive diagnostic technique, IRT was also introduced in the Earth Sciences, especially in the volcanology and environmental fields, yet its application for geostructural surveys is of recent development. Indeed, the acquisition of thermal images on rock masses could be an efficient tool for identifying fractures and voids, thus detecting signs of potential failures.<br>Further tests of thermal cameras on rock masses could help to evaluate the applicability, advantages and limits of the IRT technology for characterizing rock masses in different geological settings.<br>We present some results of IRT surveys carried out in the coastal area of Polignano a Mare (southern Italy), and their correlation with other remote sensing techniques (i.e. <em>Terrestrial Laser Scanning</em> and <em>Structure from Motion</em>). The case study (<em>Lama Monachile</em>) is represented by a 20 m-high cliff made up of Plio-Pleistocene calcarenites overlying Cretaceous limestones. Conjugate fracture systems, karst features, folds and faults, were detected in the rock mass during field surveys. In addition, dense vegetation and anthropogenic elements, which at places modified the natural setting of the rock mass, represent relevant disturbances for the characterization of the rock mass. In this context, IRT surveys were added to the other techniques, aimed at detecting the major discontinuities and fractured zones, based on potential thermal anomalies. <br>IRT surveys were carried out in December 2020 on the east side of the rock mass at <em>Lama Monachile</em> site. Thermal images were acquired every 20 minutes for 24 hours by means of a FLIR T-660 thermal imager mounted on a fixed tripod. Ambient air temperature and relative humidity were measured during the acquisition with a pocketsize thermo-hydrometer. A reflective paper was placed at the base of the cliff to measure the reflected apparent temperature. In addition, three thermocouple sensors were fixed to the different lithologic units of the rock face. These parameters, together with the distance between the FLIR T-660 and the rock face, were used in order to calibrate the thermal imager and correct the apparent temperatures recorded by the device, during the post-processing phase. Successively, vertical profiles showing the temperature of the rock face over time were extracted from the thermograms. Thermal anomalies were correlated with stratigraphic and Geological Strength Index profiles, obtained by means of field surveys and Structure from Motion techniques. The presence of fracture and voids in the rock mass was also investigated.</p>

Indonesia is an archipelago country with a sea larger than the mainland, so it is undeniable that in Indonesia there are many fisherman settlements. Often fishermen settlements in Indonesia are marginalized in the development of maritime and service industries and even become victims of the activities of the utilization of coastal areas by the private sector engaged in tourism, industry, and services. The fisherman settlement community is not getting a positive impact from the development, therefore this study aims so that the fisherman settlement community can get a positive impact from the development of the surrounding area. This research takes a case study in the fisherman settlements of Kingking and Karangsari in Tuban Regency, East Java. The approach used in this research is the urban assemblage approach to reveal socio-cultural knits as a cultural force that shapes the sustainability of the place. The urban assemblage approach will be supported by search methods which will then be analyzed descriptively qualitatively. The search was carried out through literature review and field surveys. This research presents the results in the form of a mapping of knits between culture, social, the economy as the cultural strength of the Kingking and Karangsari fisherman settlements with the surrounding tourist areas. The results of this study can be considered by the government and local communities in planning the development of coastal areas or fisherman settlements into tourist destinations.

Recently the planning of green infrastructure (GI) has become a general practice around metropolis (Paris, München, Budapest, etc). A complex methodology is required that goes beyond the scope of traditional green surface systems. However, there are various policy implications in the EU, the smaller towns are lagging to apply them. The paper presents a potential evaluation method through the case study of Keszthely, HU. As Keszthely at Balaton Riviera, is a popular touristic target of CEE, the environmental planning is an essential part of sustainable development. After a literature analyses of assessment methods of GI and ecosystem services, the aspects of GI have been valued on grade scales, based on field surveys and indicators. The current status of the GI was surveyed which is a base for further development and monitoring activities. The paper introduces the methodology, which contributes to preservation of ecosystems.

The high rate of migration, coupled with population increase triggered rapid urbanization. However, a great proportion of the population still lives in substandard and low quality houses in a deplorable unsanitary residential environment particularly in developing countries. Urban and Economic growth have brought about all typical problems associated with rapid urban development resulting in housing shortage both quantitative and qualitative, slums, illegal settlement and squatting as experienced in owerri municipality. These have resulted into many urban and housing problems within the state capital owerri. This study examined the nature of urban growth and housing problems in owerri municipality. Also it tries to examine residential housing stock, identity the nature of housing problems, government policies and programmes in other to address the problems. The pattern of growth was determined using spatial analysis, and the housing problems were identified through questionnaire and field surveys. Findings revealed that the growth of urban housing in owerri municipality increases by 1034.0 hectare which is equivalent to 38.5% which is in line with Maurice (2004). It was also discovered that over a period of time, new settlements have evolved. Also, the construction and expansion of road networks are evidences of urban growth in owerri municipality. KEYWORDS: Development, Urban growth, Housing problems, population, owerri municipality.
