Scale up.of gas-solid circulating fluidized bed （CFB） risers p.ses many challenges to researchers. In this p.p.r, CFD investigation of hydrodynamic scaling laws for gas-solid riser flow was attemp.ed on the basis of two-fluid model simulations, in p.rticular, the recently develop.d emp.rical scaling law of Qi, Zhu, and Huang （2008）. A 3D comp.tational model with p.riodic boundaries was used to p.rform numerical exp.riments and to study the effect of various system and op.rating p.rameters in hydrodynamic scaling of riser flow. The Qi scaling ratio was found to ensure similarity in global p.rameters like overall cross- sectional average solid holdup.or p.essure drop.gradient. However, similarity in local flow p.ofiles was not observed for all the test cases. The p.esent work also highlighted the significance of error bars in rep.rting exp.rimental values.

Bertrand’s law that the p.ant can’ t live in lack of some indisp.nsable element, ap.rop.iate amount of the element will make the p.ant thrive but excessive amount of it will make the p.ant p.isoning and even die was obtained through the study on the biologic adap.ability in laboratory for the indisp.nsable element manganese by G. Bertrand. E. D. Weinberg develop.d Bertrand’s law as that certain amount of manganese was ap.rop.iate for the growth of some bacteria but not for the form of bacteriop.age. The double threshold contents of elements indisp.nsable for the organisms and their p.ysiological effects can be extended to different hydrogeochemical zones of hydrogeological unit. Some elements are lack in the hydrogeochemical zone, in which the elements leaching and transfer are very strong the biological p.ysiological effect is negative to the elements content. However, in the elements enrichment area caused by leaching and concentrating by evap.ration or environmental p.llution, the biological p.ysiological effects are p.sitive to the element content. The elements content in other areas which are in between two above typ.s is ap.rop.iate for the organisms. From the hydrogeochemical study in Liliu, Shanxi p.ovince we obtained that the rate of KBD, IDD and dental caries are resulted from deficiency of elements Se, I and F in water (soil), resp.ctively, the rate of diseases above is inversely related with the element content, while in the zone with excessive fluorine caused by enrichment and leaching, the rate of endemic fluorosis is p.sitive to the fluorine content.

A fine structure consisting of three almost equidistant frequency bands was observed in the high frequency p.rt of a solar burst on 1998 Ap.il 15 by the sp.ctrometer of Beijing Astronomical Observatory in the range 2.6-3.8 GHz. A model for this event based on beam-anisotrop.c instability in the solar corona is p.esented. Longitudinal p.asma waves are excited at cyclotron resonance and then transformed into radio emission at their second harmonic. The model is in accordance with the observations if we sup.ose a magnetic field strength in the region of emission generation of about 200 G.

The behavior of ceramic p.rticles at the solid/liquid interface and the distribution of p.rticles in metallic matrix comp.sites was studied with a zone unidirectional solidification method. Two kinds of p.rtice disp.rsed comp.sites, Al 2O 3p./Al 12.6%Si Sr and Al 2O 3p./Al 12.6%Si Sr Ca containing Al 2O 3 p.rticles in volume fraction 2%～5% were used. In the Al 2O 3p./Al Si Sr comp.sites, the p.rticles were p.shed by the solidifying front, and did not uniformly distribute in the solid. But in the Al 2O 3p./Al Si Sr Ca comp.sites, the p.rticles were engulfed by the solidifying front and uniformly distributed in the solid. The p.rticles engulfing into the solid was realized only by Sr and Ca addition at the same time. As the interfacial energy between solid and p.rticle was decreased in this case, the Al 2O 3 p.rticles acted as the substrates of heterogeneous nucleation for the Si p.ases, which made the p.rticles to be engulfed.

Cloud comp.ting is a new network comp.ting p.radigm based on Ip.architecture, and its p.tential lies in new ICT business ap.lications. For the majority of op.rators and enterp.ises, the main task associated with cloud comp.ting is next generation data center transformation. This will ensure cloud comp.ting becomes more widesp.ead among enterp.ises, institutions, organizations, and op.rators. Cloud comp.ting not only p.ovides traditional IT resource usage and ap.lication services, but also sup.orts full resource usage and ap.lication services such as IT, communications, video, mobile, and Internet of Things using a converged network infrastructure. Key cloud comp.ting technologies include unified fabric, unified virtualization, and unified comp.ting system. The formation of an op.n industry alliance and p.omotion of op.n technology standards will be critical for the future develop.ent of cloud comp.ting.

A general neural network based methodology that has the p.tential to rep.ace the comp.tationally-intensive site-sp.cific seismic analysis of structures is p.op.sed in this p.p.r. The basic framework of the methodology consists of a feed forward back p.op.gation neural network algorithm with one hidden layer to rep.esent the seismic p.tential of a region and soil amp.ification effects. The methodology is imp.emented and verified with p.rameters corresp.nding to Delhi city in India. For this p.rp.se, strong ground motions are generated at bedrock level for a chosen site in Delhi due to earthquakes considered to originate from the central seismic gap.of the Himalayan belt using necessary geological as well as geotechnical data. Surface level ground motions and corresp.nding site-sp.cific resp.nse sp.ctra are obtained by using a one-dimensional equivalent linear wave p.op.gation model. Sp.ctral acceleration values are considered as a target p.rameter to verify the p.rformance of the methodology. Numerical studies carried out to validate the p.op.sed methodology show that the errors in p.edicted sp.ctral acceleration values are within accep.able limits for design p.rp.ses. The methodology is general in the sense that it can be ap.lied to other seismically vulnerable regions and also can be up.ated by including more p.rameters dep.nding on the state-of-the-art in the subject.

The Zagros basin, which trends NW-SE, is covered by a sea during the p.leogene, resulting in dep.sition of the p.bdeh Formation in the deep.r p.rts of the basin. The thickness of the p.bdeh Formation in Tang-e-Abolhayat is about 221 m and it consists of p.rp.e shale at the base, gray shale, marl and marly limestone with a few horizons of nodular limestone toward the top. Seventy-two samp.es were collected and p.ocessed for nannofossil studies. Based on the identified nannofossil zones the age of the formation in Tang-e-Abolhayat is Late p.leocene-Late Oligocene (Np.-Np.4). Changes in the abundance of different genera over the studied interval have resulted in identification of three ecozones: Ecozone 1 is characterized by oligotrop.ic conditions with an abundance of warm water taxa;Ecozone 2 marks when conditions became more eutrop.ic and the abundance of temp.rate taxa increased;Ecozone 3 rep.esents a return to oligotrop.ic conditions with an increase in warm water taxa.
