Modifications of surface materials and their effects on cleanability as studied by radiochemical methods

Modifications of surface materials and their effects on cleanability have important impacts in many fields of activity. In this study the primary aim was to develop radiochemical methods suitable for evaluating cleanability in material research for different environments. Another aim was to investigate the effects of surface modifications on cleanabilitity and surface properties of plastics, ceramics, concrete materials and also their coatings in conditions simulating their typical environments. Several new 51Cr and 14C labelled soils were developed for testing situations. The new radiochemical methods developed were suitable for examining different surface materials and different soil types, providing quantitative information about the amount of soil on surfaces. They also take into account soil soaked into surfaces. The supporting methods colorimetric determination and ATP bioluminescence provided semi-quantitative results. The results from the radiochemical and supporting methods partly correlated with each other. From a material research point of view numerous new materials were evaluated. These included both laboratory-made model materials and commercial products. Increasing the amount of plasticizer decreased the cleanability of poly(vinyl chloride) (PVC) materials. Microstructured surfaces of plastics improved the cleanability of PVC from particle soils, whereas for oil soil microstructuring reduced the cleanability. In the case of glazed ceramic materials, coatings affected the cleanability. The roughness of surfaces correlated with cleanability from particle soils and the cleanability from oil soil correlated with the contact angles. Organic particle soil was removed more efficiently from TiO2-coated ceramic surfaces after UV-radiation than without UV treatment, whereas no effect was observed on the cleanability of oil soil. Coatings improved the cleanability of concrete flooring materials intended for use in animal houses.

Geoarchaeological Evidence of a Chola-Period Tsunami from an Ancient Port at Kaveripattinam on the Southeastern Coast of India

Literature of the ancient Chola Dynasty (A.D. 9th-11th centuries) of South India and recent archaeological excavations allude to a sea flood that crippled the ancient port at Kaveripattinam, a trading hub for Southeast Asia, and probably affected the entire South Indian coast, analogous to the 2004 Indian Ocean tsunami impact. We present sedimentary evidence from an archaeological site to validate the textual references to this early medieval event. A sandy layer showing bed forms representing high-energy conditions, possibly generated by a seaborne wave, was identified at the Kaveripattinam coast of Tamil Nadu, South India. Its sedimentary characteristics include hummocky cross-stratification, convolute lamination with heavy minerals, rip-up clasts, an erosional contact with the underlying mud bed, and a landward thinning geometry. Admixed with 1000-year-old Chola period artifacts, it provided an optically stimulated luminescence age of 1091 perpendicular to 66 yr and a thermoluminescence age of 993 perpendicular to 73 yr for the embedded pottery sherds. The dates of these proxies converge around 1000 yr B. P., correlative of an ancient tsunami reported from elsewhere along the Indian Ocean coasts. (C) 2011 Wiley Periodicals, Inc.

Timna revisited : egyptian chronology and the copper mines of the southern Arabah

This article studies the chronology of the New Kingdom Egyptian copper mining in the southern Arabah valley, and particularly Timna, traditionally dated in the 13th– 12th centuries BCE. a reassessment is made of the local archaeological evidence and especially of the findings of the Hejazi Qurayya pottery in archaeological assemblages of the southern Levant. It is argued that the chronology of the New Kingdom activities at Timna needs a revision towards lower dates.

A possible alchemist apparatus from the early islamic period excavated at Ramla, Israel

Abstract: During extensive salvage excavations carried out during the years 2004-2008 in a large Early Islamic industrial area at the vicinities of Ramla, in Central Israel, an unparalleled industrial device was unearthed. The star-shaped, soil embedded installation, whose lower part was preserved, consisted of a central pottery jar surrounded by five minor jars, linked by ceramic pipes. Evidence of heat was observed mainly around the central vessel, and metal hollow cones perforated in the tip were found inside the surrounding jars. Although the manufacturing procedures and operation techniques of the installation are not completely clear, it is proposed that the installation is part of an industrial workshop or an alchemy laboratory. Both industry and alchemy were well-developed during the Early Islamic period and very often closely related, to the point that sometimes it is difficult to distinguish between them. The identification proposed is based on comparisons with tools described in literary sources, and somewhat later drawings and etchings. Circumstantial ceramic evidence was found, as well as the proximity of a bathhouse whose guests could have been the consumers of perfumes and unguents seem to reinforce this possibility. Due to the poor state of preservation of the device and the lack of available comparisons, the identification proposed here is tentative, and future research coupled with eventual new discoveries is needed in order to clarify this matter.

Influência do acabamento e polimento na resistência à flexão de uma cerâmica odontológica

Avaliou-se a influência de dois sistemas de acabamento e polimento na resistência à flexão de uma cerâmica feldspática EX-3 (Noritake). Para isto, confeccionou-se blocos cerâmicos com medidas em conformidade com a ISO 6872/1995. Em seguida obteve-se o glaze natural. A padronização da rugosidade superficial foi conferida com auxílio de um rugosímetro, e os blocos foram então divididos em cinco grupos. O Grupo I (controle) foi testado com glaze. Para os testes realizados nos demais grupos, os blocos receberam um tratamento de asperização por meio de uma ponta diamantada 4137 (KG Sorensen). Em seguida foram polidos com diferentes protocolos. No grupo II, o sistema de polimento dura white (Shofu). No grupo III, o sistema de polimento dura white (shofu) associado a uma pasta diamantada aplicada com disco de feltro. No grupo IV o sistema de polimento Exa Cerapol (Edenta) e no grupo V, este mesmo sistema mais pasta diamantada aplicada com disco de feltro. Após os procedimentos de acabamento e polimento, foi avaliada a rugosidade conseguida (Ra), para se avaliar a eficácia dos métodos testados. A análise estatística por ANOVA (p ≤ 0,05) mostrou não haver diferença estatisticamente significante entre os grupos (G2=3,820,58; G3=3,550,61; G4=4,050,40; G5=3,950.47) . Feito isto, os corpos-de-prova foram submetidos a um ensaio mecânico de resistência à flexão em três pontos, e também neste caso, os resultados depois de tratados estatisticamente não demonstraram diferenças estatísticas entre os grupos glazeados e os grupos que receberam tratamento (G1=132,126,9 MPa; G2=123,317,4 MPa; G3=114,519,3 MPa; G4=104,211,9 MPa e G5=104,719,1 MPa) . Após a realização destas avaliações, tornou-se possível concluir que o uso dos sistemas de acabamento e polimento testados neste trabalho permite obter superfícies com rugosidade similar a obtida com o glaze natural e não interferem na resistência à flexão da cerâmica utilizada.

Cerámica cardial en la Rioja Alavesa

[ES] Se trata de dar a conocer el descubrimiento de cerámica impresa de tipo cardial en la Rioja Alavesa. Tales hallazgos se han localizado durante las excavaciones que se están realizando en el Abrigo de Peña Larga en Cripán (Alava) desde el verano de 1985. Las fechas obtenidas para el nivel de donde proceden las referidas cerámicas son: -5830 BC (para la parte superior del nivel). -6150 BC (para la parte baja en la que se encuentran las citadas cerámicas). Esta cronología sitúa el nivel en un Neolítico pleno en consonancia con los niveles cardiales localizados en las últimas décadas en el valle del Ebro.

Preservation of fish by freezing and glazing. Pt. 2. Keeping quality of fish with particular reference to yellow discolouration and other allied organoleptic changes on prolonged storage

Organoleptic observations of quick, slow and block frozen, glazed and stored fish were recorded at regular intervals. Glazing was renewed at intervals of four weeks. Development of yellow discolouration in the case of white pomfret was followed. Keeping quality of glazed fish was better than unglazed frozen fish. Yellow discolouration could be controlled by ascorbic acid for 42 months and by a mixture of sodium chloride and glucose for 52 months.
