This study presents test measurements on a Lexsyg luminescence reader, acquired by the Giessen luminescence group. The reader is of the type Standard, hence designed for routine determination of palaeodoses using quartz or K-feldspars. The tests include measurements of the stimulation powers, preheat temperatures, OSL- and TL-curves, as well as dose recovery tests and calibration measurements using highly sensitised calibration quartz. A comparison of D e values determined using a Lexsyg reader with single grain D e-values, which have been previously obtained on a Risø reader, is also presented. The results imply that the Lexsyg reader is a highly reliable measurement device with high reproducibility, yielding instrumental uncertainties of around 0.3%. 相似文献

A relevant subject of study in the sphere of ancient Egyptian painting technology is given by the evolution of the palette
across New Kingdom, Ptolemaic and Roman periods. Functionally to secondary factors such as geographic occurrence of minerals
and type of associated surface, the employment of certain painting materials provides relevant insights into particular issues
such as relative dating of the object and social rank of the owner. The Book of the Dead of Amenemhet (ROM 978 × 43.1, middle Ptolemaic Period) has been analysed at the Department of Restoration and Conservation
of Archivals, Graphics and Book Illumination of the Cologne Institute of Conservation Sciences (Germany). Together with visible
reflectance spectroscopy, digital and optical microscopy, devices such as XRD, SEM-EDX and FT-IR have been successfully employed
for the characterization of the pigments from the polychrome funerary papyrus displayed at the Royal Ontario Museum, Toronto
(Canada). The present research took place within a series of investigations performed at the CICS, devoted to the interdisciplinary
study of funerary Egyptian papyri dating from the early 18th Dynasty onwards. 相似文献

The protocol of preparation of keratinized samples (e.g. hair, furs …) for radiocarbon dating that we have developed is based on the selective extraction of keratin from the bulk part of the shaft (cortex). The aim of this method is to eliminate the cuticle which could contain exogenous carbon from external contaminations. The total treatment takes place as follows: a washing/dry cleaning, a soft treatment with diluted acidic and basic solutions (acid/alkali/acid method) similar to the protocol used for vegetal samples, extraction of keratin by reduction using dithiothreitol and precipitation with sodium deoxycholate and trichloroacetic acid. This method was applied on a hair sample from an Andean mummy, conserved in the collections of the Anthropology Laboratory of the National Museum of Natural History (Musée de l’Homme) in Paris, France. The results of two runs reveal that the mummy is dated to a period between the eleventh century and the first half of the twelfth century. It therefore belongs to the Late Intermediate period (900–1450?ad). The combination of historical research, the study of the body by computed tomography and the analysis of mineral deposits on the surface of the body provides clues to identify the geographical origin of the mummy. These investigations led to determine that the mummy comes from the region of Tarapacá in Chile and belongs to the cultural complex Pica-Tarapacá. 相似文献

Hobbes is commonly treated as a foundational figure for liberalism. This familiar view relies on emphasizing his account of the relationship between rights bearing individuals and state power. By contrast, this essay centers the practical question of how to govern, and develops this perspective to both question Hobbes's supposed liberalism and to demonstrate the utility of construing liberalism as more than a set of philosophical arguments regarding subject-state relations. In particular, understanding liberalism in terms of political technique offers a new perspective on the relationship between liberalism and republicanism. 相似文献

There is no discussion about the historic relevance of I. Sechenov for physiology and neurosciences as the "father of Russian modern physiology". But he is relevant for modern natural science too because of his basic epistemological and ontological work. He did not accept the up to now basic paradigm of "Ignorabimus" which can be seen as the reason to exclude even the generalizable aspects of individuality, creativity and spontaneity from natural science. He developed techniques for empirical based science to deal with materialistic and idealistic aspects of the comprehensive person the "ignoramus" according to the actual stay of knowledge and the acceptable ontologies. He demonstrated that ontologies ("paradigms") can be used as tools according to the given problem which should be solved. So Sechenov can be seen as a precursor of the so efficient philosophical positions of Einstein and Th. Kuhn. The stay of the art in physiology and neurosciences changed since the time of Sechenov dramatically. Therefore the philosophical positions of the 19th century should be discussed. Maybe this is indispensable for the needed linkage between materialistic and idealistic aspects of a person. For this the proposals of Sechenov are helpful up to now but nearly unknown.

In this respect the proposals of Sechenov are helpful for medical science in the twenty-first century too but nearly unknown. 相似文献

This paper presents an update on some of the activities that have taken place since a World Bank report; “Guidelines for Education and Training in Environmental Information Systems in Sub-Saharan Africa: Some Key Issues” was published and provides details on the current situation. It shows how organizations such as the African Association on Remote Sensing of Environment, International Society of Photogrammetry and Remote Sensing, European Association of Remote Sensing Companies, Group on Earth Observation, and several others have helped to increase manpower resources in the region and strengthened institutional capacity in the field of geoinformatics, through capacity building, technology transfer, international cooperation and the provision of internal African resources. After reviewing what has happened in the field of geoinformatics education and training, we focused on current initiatives taken and challenges in five Sub-Saharan countries: Ethiopia, Nigeria, South Africa, Tanzania, and Zimbabwe. We reviewed GIS education and training in the private sector, government, information communications technology in higher education institutions, GIS application areas and challenges facing GIS education and training. Findings show that; change should involve education stakeholders in all levels of education and curriculum quality, regional and international cooperation through exchange programs, should be a priority for Sub-Saharan Africa countries. 相似文献
