A comparative analysis of Late Jurassic-Early Cretaceous strata have been done for the sanjiang Middle Amur basin, a coaland oil-bearing area spanning the eastern Heilongjiang of northeastern China and southeastern Far East of Russia. On the basis of various fossils occurring in the formations, particularly by means of the Tithonian-Valanginian index Buchia and the late Barremian-middle Albian indicator Aucellina assemblages, the marine and non-marine Late Jurassic-Early Cretaceous strata in the basin are correlated. The Mesozoic international chronostratigraphic chart (http://*** ***) is established basically based on the marine rock.. To accurately date the non-marine strata, it is necessary to correlate them with the marine deposits. This study sheds new light on the dating and correlation of non-marine Upper Mesozoic. Additionally, the results would help understand the tectonics and paleogeography and thus aid the exploration of energy resources.

Achievable supercooling for the formation of methane hydrate from water emulsions was studied in seven different crude oils and in decane. The experiments were performed under constant rate cooling from + 20 to-15 °C and a pressure of methane of 12 MPa. It was demonstrated that the shapes and positions of the resulting survival curves depend on the density, viscosity and dispersive power of oil samples used in the experiments, as well as on the degree of oil oxidation. In addition, results of the experiments on ice freezing under the same emulsions are presented. The results obtained in the work.allowed us to discuss the possibility and features of primary and secondary nucleation of the hydrate and ice in the systems under consideration.

We discuss recent measurements of exclusive e^＋e^- cross sections for charmed hadron final states near threshold performed by Belle and BABAR. The results are based on a study of events with initial-stateradiation photons in a large data sample collected with the Belle and BABAR detectors at the T（4s） resonance and nearby continuum.

In this work. the local fracture initiation behaviour of an Al2O3/6061Al composite is studied numerically. The damage behaviour of the microstructure is evaluated in consideration of the path and the amount of damage as well as the stress-strain performance of the microstructure. The damage behaviour of the ductile matrix has been simulated using the damage parameter D. For the simulation of fracture of the ceramic particles, a normal stress criterion is applied. For the analysis of the damage behaviour of the transition zone between particulate and matrix, both damage models （D parameter and normal stress criteria） are applied in this region. Parameter studies of crack.propagation prediction in the Al2O3/6061Al composite on the basis of an Element Elimination technique have been performed for two differently heat-treated variants resulting in different mechanical properties. In addition, residual stress effects on the damage behaviour are examined for various microstructural situations.

Global warming causes changes of those natural resources lik. power resources, water resources, agroclimatic and ecological resources etc. And these changes depend on climate. Dynamics of resources depends both on planned economic activities and on changes of a climate. In this work.the climatic component of changes is discussed. Projecting results used in this paper are based on the data of the CMIP3 (coupled model intercomparison project) in the framework.of Work.ng Group on Coupled Modelling. This project includes the world’s best climate models. Results of modelling and the data of meteorological observations expressed by probability distribution functions (or empirical orthogonal functions) were compared. It was shown that the modelling data were much more reliable over flat territories. In result 11 most successful models were selected. They can be used for the forecast within the framework.of k.own IPCC scenario A2 at the 21st century. Estimations of changes of volumes of a river runoff and conditions of humidity of territory have been allowed to determine that the serious reduction of resources is expected in the southern part of the East European plain. Its central and northern parts practically will not demonstrate changes.

Androgen receptor (AR), a hormonal transcription factor, plays important roles during prostate cancer progression and is a k.y target for therapeutic interventions. While androgen-deprivation therapies are initially successful in regressing prostate tumors, the disease ultimately comes back.as castration-resistant prostate cancer (CRPC) or at the late stage as neuroendocrine prostate cancer (NEPC). CRPC remains largely dependent on hyperactive AR signaling in the milieu of low androgen, while NEPC is negative of AR expression but positive of many AR-repressed genes. Recent technological advances in genome-wide analysis of transcription factor binding sites have revealed an unprecedented set of AR target genes. In addition to its well-k.own function in activating gene expression, AR is increasingly k.own to also act as a transcriptional repressor. Here, we review the molecular mechanisms by which AR represses gene expression. We also summarize AR-repressed genes that are aberrantly upregulated in CRPC and NEPC and represent promising targets for therapeutic intervention.
