The persistent uncertainty on the classification of the “new” glume wheat found in Neolithic and Bronze Age sites from Greece and other European settlements might be resolved only through analysis of its ancient DNA. Tools able to discriminate among different Triticum species on the basis of scarce, very damaged DNA, are therefore essential. While current attempts concentrate on DNA fragments sequencing and comparison, in some instances PCR-based selective amplification techniques might offer a cheaper and quicker alternative. The purpose of this research was therefore the identification of species-specific primers, able to distinguish caryopses of Triticum timopheevii subsp. timopheevii from those of Triticum turgidum subsp. dicoccum. Primers and their working conditions were defined and optimized using DNA from modern accessions. The ribosomal primers ITS1 tim and ITS2 tim, and the nuclear primer acetyl-coenzyme A tim clearly discriminated the sequences of Triticum timopheevii from other species. Finally, Neolithic charred wheat grains found in the sites of Sammardenchia (Pozzuolo del Friuli, Udine) and La Marmotta (Lago di Bracciano, Roma), belonging to the “new” wheat type or to emmer, were tested with the three selected primers. However, the results were not conclusive, because the samples analysed were apparently too degraded to yield useful DNA. 相似文献

The joint application of electric and magnetic techniques for near-surface exploration represents a very useful tool for archaeological investigation and can provide a quantitative contribution to describe the spatial distribution of buried objects. In this work we show a new advanced tomographic approach, based on the parallel inversion of magnetic and electric observed data, aimed at the reconstruction of the subsoil of a still unexplored area of the archaeological site of Pompeii (Southern Italy). The survey was performed in collaboration with Pompeii's Archaeological Commission. The comparison between the results obtained from the tomographic inversions of both electrical and magnetic data was carried out in terms of the data inversions, which allowed us to obtain information about the location of the buried geophysical sources in the investigated subsoil. The results obtained seem to be in a good agreement, both for the position of the geophysical sources and for their dimensions. 相似文献

Energy-dispersive X-ray fluorescence (EDXRF) and lead isotope analyses were applied to 12 Western Zhou (1046–771 bc) bronzes unearthed from the Shuangyantang site in Wushan County, Chongqing (southwest China), to investigate their chemical compositions and possible mineral source(s). The results showed that (1) the investigated bronzes were mostly bronzes with low, common lead and (2) their lead isotopic values almost all fall into a relatively narrow range, suggesting possibly the use of raw materials from a common copper mine. The comparison between lead isotopic values for Shuangyantang bronzes and those already published for copper mines and other bronzes produced and used about at the same times leads us to believe that the Shuangyantang bronzes probably used the same copper ores as used in bronzes from the Peng and Jin states in Shanxi Province. However, it would not be possible at this point to come up with a clear idea of where exactly these copper ores may come from. Candidate copper mines might be the Tonglvshan mines in Hubei Province, the Zhongtiaoshan mines in Shanxi Province, or the Dajing copper mines in Inner Mongolia. 相似文献

Local innovation networks are considered to be important to innovation and technological change and to growth prospects of regions and cities in Germany. When analysing the local (or regional) innovation system, one should consequently not only investigate horizontal and vertical relations among firms but also the contacts with universities and other research institutions. Furthermore, the role of government agencies and interest groups that provide financial support as well as commercial and technical information should also be taken into account. However, the review of relevant theoretical and empirical investigations related to the German experience shows that such innovation and R&D cooperation networks appear to be less significant than expected. In general various regional technology policy measures adopted in German states (the provision of research infrastructure, establishment of technology centres, innovative small and medium sized enterprises support programmes, etc.) have been more successful in economically better-off large cities than in the rural areas. Apart from offering a critical review of relevant theoretical and empirical research, this study introduces the present regional technology and R&D promotion policies in German states and examines the local innovation systems, taking Landshut as an example. 相似文献

考察我国古代刑法中的身份具有重要的现实意义。可将我国古代刑法中的身份分为五个方面:(1)基于生物学特征之身份。又可分为两类:一类是年龄和疾病;另一类是妇女和孕妇。(2)基于职务、职业之身份。(3)亲属身份。具体包括亲属相犯、亲亲相隐、族诛与缘坐、亲属相奸等方面。(4)社会等级身份。具体包括等级特权和良贱相犯。(5)共同犯罪中的身份。其中,唐律的有关规定最为细致、完备。 相似文献
