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

Henkama, ?Daddy Heng“ – A Mediator between the Kangxi Emperor and Jesuit Missionaries during Chinese Rites Controversy in the 18th CenturyThe author's main concern is to turn the somewhat enigmatic person of Henkama (1645/1646–1708), known under many (also false) names, into a more tangible historical figure. For this purpose, all the available sources in European languages, Manchu, and Chinese are taken into account. Beginning with investigating the very name of this Manchu official who was responsible for the administration of the affairs of the Europeans, the author tries to obtain available and solid knowledge of Henkama's life and work, possibly year by year, which goes far beyond what is normally known about him, i.e., his role as main intermediary during the papal legation in Beijing (December 1705 – August 1706). However, this mediatory role cost him the trust of all around him, including the Kangxi Emperor, who was convinced that Henkama had been paid off by the papal legate and cardinal Charles-Thomas Maillard de Tournon (1668–1710). At the end of his life, being in ill health, he became a Catholic. Henkama died in 1708 in disfavor due to slander. In the rest of his article, the author depicts another four important contact persons between the Kangxi Emperor (state administration) and Jesuit missionaries, all of whom are to be considered as Henkama's co-workers or his successors. Among these four, there are two Chinese – Zhao Chang (1654–1729) and Wang Daohua (fl. 1706–1720) and two persons of Manchu origin – Bursai (fl. 1705–1706) and Zhang Changzhu/Carki (fl. 1707–1722). 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.

Therefore, the philosophical positions of the nineteenth century should be questioned. Maybe this is indispensable for the needed link between materialistic and idealistic aspects of a person as a whole. 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
