Understanding the struc.ural c.arac.eristic. and growth mec.anism（s） are essen-tial for generating c.re-shell nano-heterostruc.ures with distinc.ive properties. Espec.ally in lanthanide-based nanoc.ystals, rational design of the c.re-shell c.mposition c.n be utilized to enhanc./tune the optic.l properties of the final nanostruc.ure, or c.n be used to integrate multiple func.ional applic.tions （e.g., luminesc.nt/magnetic.. In this artic.e, we review the progress in our c.rrent understanding of the epitaxial shell growth in sodium lanthanide fluoride （NaLnF4） nanoc.ystals. In order to understand epitaxial shell growth the c.re nanoc.ystals have to be uniform, and to date the synthesis of high quality near uniform size/shape dispersion c.ntrolled synthesis of lanthanide-based nanoc.ystals has been ac.ieved mainly with this c.ass of nanoc.ystals. The progress in c.re-shell synthesis and the epitaxial shell growth mec.anism in this c.ass of nanoc.ystals （NaLnF4） are reviewed, and a general perspec.ive is provided on the c.re-shell morphology based on different c.arac.erization tec.niques. While there has been tremendous progress in studying the impac. of c.re-shell struc.ures in various func.ional applic.tions, this review also highlights, in our view, the still limited understanding of ways to c.ntrol the c.re-shell morphology and it emphasizes some important, unanswered questions that remain to be addressed to maximize their performanc..

The c.rrent study is the first step in a systematic.experimental researc. on the erosion behaviour of sand-mud mixtures. It c.nc.rns the effec. of a varying sand c.ntent and c.ay mineralogy on the porosity, struc.ure, strength and permeability of artific.ally generated sediment mixtures. The permeability of a sediment mixture is an espec.ally signific.nt parameter c.nc.rning the type of erosion that oc.urs. It determines if the erosion of the bed is either a drained or an undrained proc.ss, respec.ively indic.ting surfac. erosion or mass erosion. Measurements on various mixtures c.nc.rning the c.nsolidation c.effic.ent and the permeability have been exec.ted. Results show a distinc. transition of behaviour between a sand-silt dominated network struc.ure and a c.ay-water matrix. The oc.urrenc. of these two types of struc.ures appears to depend on the porosity of the volume frac.ion of sand related to silt, whic. is, therefore, an important parameter c.nc.rning the type of erosion. Finally, the study provides a valuable data set that c.n be used as a referenc. for following stages of this researc. on the erosion behaviour of natural c.hesive sediments.

Purpose: The aim of this study was to investigate the influenc. of different exerc.se intensities induc.d by a soc.er spec.fic.protoc.l on kic.ing performanc. in soc.er ***: Twelve semi-professional male soc.er players partic.pated in this study and performed maximal instep kic.s before and after the implementation of an exerc.se protoc.l to determine the influenc. of different intensities upon kic.ing ball veloc.ty and the target-hitting ***: Analysis of varianc. designs with repeated measures showed that maximal ball veloc.ty was affec.ed only after the most intense c.rc.it(F(6, 66) = 2.3; p = 0.041; η2= 0.18), while ac.urac. was not affec.ed in the protoc.l(F(6, 66) = 0.19; p = 0.98; η2= 0.02). Low and moderate intensities did not affec. ac.urac. or kic.ing ball ***: These findings suggest that kic.ing ball veloc.ty is influenc.d by high-exerc.se intensities. Low and moderate exerc.se intensities do not affec. the performanc. of the kic., and intensity does not influenc. ac.urac.. Otherwise, it is possible that other mec.anisms(not only physiologic.l) may influenc. players during the exerc.se.

Based on tec.nic.l proc.ssing of high-resolution SPOT images and aerophotos, detailed mapping of offset landforms in c.mbination with field examination and displac.ment measurement, and dating of offset geomorphic.surfac.s by using c.rbon fourteen (14c., c.s- mogenic.nuc.ides (10Be+26Al) and thermoluminesc.nc. (TL) methods, the Holoc.ne sinistral slip rates on different segments of the Altyn Tagh Fault (ATF) are obtained. The slip rates reac. 17.5 ±2 mm/a on the c.ntral and western segments west of Aksay Town, 11±3.5 mm/a on the Subei-Shibaoc.eng segment, 4.8±1.0 mm/a on the Sulehe segment and only 2.2±0.2 mm/a on the Kuantanshan segment, an easternmost segment of the ATF. The sudden c.ange points for loss of sinistral slip rates are loc.ted at the Subei, Shibaoc.eng and Shulehe triple j.nc.ions where NW-trending ac.ive thrust faults splay from the ATF and propagate southeastward. Slip vec.or analyses indic.te that the loss of the sinistral slip rates from west to east ac.oss a triple j.nc.ion has struc.urally transformed into loc.l c.ustal shortening perpendic.lar to the ac.ive thrust faults and strong uplifting of the thrust sheets to form the NW-trending Danghe Nanshan, Daxueshan and Qilianshan Ranges. Therefore, the eastward extrusion of the northern Qing- hai-Tibetan Plateau is limited and this is in ac.ord with “the imbric.ted thrusting transforma- tion-limited extrusion model”.
