Seventeen species of mollusca have been identified, which belong to two classes: Bivalvia and Gastropoda. The compositions of the mollusca are very simple. According to the distribution pattern two groups may be distinguished among molluscan species. The Pan-Arctic and circumboreal group comprises Nuculana pernula, N.radiata, Nucula bellotii, Astarte montagui, Seripes groenlandicus, Macoma calcarea, M. moesta alaskana, Liocyrna fluctuosa, Mya pseudoarenaria and Turritella polaris. Three species, Cyclocardia crebricostata, Trichotrois coronata and Argobuccinum oregonense are components of the Pan-Arctic and Pacific boreal group. With regard to feeding habits, detritus feeders dominate. There are 7 species of detritus feeders, i.e., Nuculana pernula, N. radiata, Nucula bellotii, Macoma calcarea, M. moesta alaskana, Macoma sp. and Trichotropis coronata. Detritus feeders are dominant with regard to the numbers of species as well as to the frequency of occurrence. Macoma calcarea is the most abundant species.展开更多

In the mid-low mountain areas, the existence of Quaternary glacier as well as its range and nature are always controversial. The glacial paleogeomorphology of Northeast China had been extensively studied and explored. The results revealed that Quaternary glaciers was developed in the northern part of Great Hinggan Ranges and Changbai Mountains. However, some scholars believed that the development of the Quaternary glaciers in China resulted from tectonic coupling and close relation with the elevation of mountains. In Northeast China, glaciation did not occur in any mid-low mountain areas during the Quaternary except the Changbai Mountains where the elevation is more than 2600 m. The question is whether glaciation occurred in the mid-low mountain areas of Northeast China during the Quaternary？ In order to clarify this question, this paper reports the Quaternary glacial remains of Tala Mountain, which were newly discovered in Ar Horqin Banner, lnner Mongolia and their age dating.展开更多

This historical site belongs to 9th century A.D. All the samples selected for the study were dried in room temperature as well as hot air oven at 32 ~C. Cleaning, pretreatment and digestion process of faunal remains was followed through established scientific methods. Chemical analysis i.e. concentration of different elements such as calcium, strontium, barium, magnesium and zinc as well as isotopic ratios of Carbon and Nitrogen was estimated with the help of ICP （inductively coupled plasma spectroscopy） and AAS （atomic absorption spectrophotometer）. The results obtained from the chemical analysis are significant. On the basis of concentration of different elements and ratios of Nitrogen and Carbon isotopes, the dietary habits of the peoples buried in the Roopkund Lake are identified, which is different from sample to sample person to person. Besides this, the results are also significantly helpful for knowing the preservation status of faunal remains in Roopkund Lake. Finally this study also indicated the potentiality of chemical analysis for reconstructing the palaeodiet behaviour and preservation status of bone remains.展开更多

The lining of the avenue was erased. Centuries over centuries this avenue has been buried with its statues under about 2 m of silt and sand, and urban development covered it with housing, asphaltic streets, and other structures, obscuring its route and interrupting this dramatic connection. This paper focuses on the discovery of some of these Sphinx statuses and remains at a suggested part of the avenue using both near-surface magnetic and shallow seismic refraction methods. A gradiometer survey was conducted in an area that amounted 576 m2 as (48 m?× 12 m) to measure the vertical magnetic gradient with a high resolution instrument with 0.25 m sampling interval. A superior detection was accomplished by using the analytic signal and Euler deconvolution techniques. The shallow seismic refraction survey was done in the same area to illustrate the lithology of layers material with 1 m interval;both P and S waves were measured to calculate the geotechnical properties of the area to sustain the sketch of structures’ boundaries. We have lucratively detected six main structures;they can be the pedestal of these Ram-headed Sphinx statues. Mining a small part of the study area has proven the reliability of, both the magnetic and shallow seismic refraction discoveries, and the shallowness and composition of the detected features.展开更多

However, protection of urban cultural heritage has been long neglected, with the rapid economic development and urbanization process, a lot of urban cultural heritage that bears important historical and cultural value had gone forever. Ancient cultural remains(ACRs) are an important type of urban cultural heritages, the renaissance of ACRs means the revival of the whole city, how to make ACRs in gradual decline state to be protected with proper planning and renewed vigor has great signifi cance to the urban development. Taking protection and development planning and design of ACRs in Mountain Haoli and its surroundings for example, this study put forward the objectives and principles of ACRs protection and development, extending and deepening the protection methods and renewal strategies, so as to achieve overall cultural, economic and spatial revival of urban ACRs, and sustainable development of ACRs.展开更多

The assemblage is composed of 13 species assignable to 10 genera. The important genera are Callimothallus senii, Haplopeltis mucoris, Haplopeltis sp., Parmathyrites sp., Phragmothyrites eocaenicus, Plochmopeltinites sp., Spinosporonites saxenae, Spinosporonites angularis and Trichothyrites padappakkarensis. The presence of microthyriaceous fungi in dominance suggests that the region experienced a warm and humid climate during the course of sediment deposition with thick vegetation providing suitable substrates for the growth and proliferation of fungi. Their presence depicts the prevalence of moist tropical type of vegetation during deposition in the area. The present fungal assemblage is assigned Late Palaeocene-Middle Eocene age.展开更多

The difficulty derives from the fact that variable environment has a significant effect on DNA preservation. During the years 2002-2015 unidentified degraded skeletal remains were accumulated at our institute, National Institute of Forensic Medicine (NIFM), most of them with none or partial DNA profile. As new methods rapidly emerge, we revisited these samples with partial DNA profiles in the hope to add additional alleles and eventually be able to identify these previously unidentifiable samples. We have chosen to use these samples to compare two automated methods: Prepfiler Express BTA (Applied Biosystems) and QIAcube (Quiagen), in hope of acquiring a more complete DNA profile and eventually make new identifications possibly comparing these profiles with missing person database. In both methods, a preparation step is required, after which the samples undergo automatic DNA extraction. The two protocols are based on different extraction methods. Fresh or non-problematic bone samples as the positive control gave the same results in both methods. In the degraded skeletal samples, the results were significantly better using the QIAcube method in our hands, but since degraded samples are highly variable the combination of both methods could be useful to receive better and more reliable profiles.展开更多
