Due to urban construction and renovation projects,a large amount of construction and demolition waste(CDW)is increasing year by year in *** them,soil-brick mixture(SBM)is most widely landfilled because many older brick buildings were constructed in the last century(Zhang et al.,2022;Xu et al.,2021).Since the SBM is composed of two kinds of geotechnical materials,its mechanical properties are more complex than those of the single *** depend not only on the mechanical properties of the individual components such as soil and brick,but also on the relative content of these components and the shape of the coarse particles(Zhu et al.,2021).The shear properties of SBM directly affect the stability of slope and paving engineering;therefore,it is significant to study the mechanical properties of SBM.

通过实地调查,分析了大理、丽江地区木结构榫卯结构的配置情况以及二者结构上的差异。为了研究二者的抗震性能与受力特性,通过有限元软件对两个地区的典型穿斗式木结构山架进行低周往复荷载模拟。结果表明:丽江地区穿斗式木结构山架抗震性能优于大理地区,两地木结构的薄弱点均在横向构件与纵向构件的榫卯节点处,榫卯节点的薄弱点位于榫头末端,二者的抗侧刚度均不高,易在水平荷载下倾斜。

ZnNiO thin films with different contents of Ni(0-10 at.%) were fabricated on quartz and Si(100) substrates by pulsed laser deposition(PLD).We measured the samples by X-ray diffraction(XRD),field-emission scanning electron microscope(FE-SEM),X-ray photoelectron spectroscopy(XPS),ultraviolet-visible spectrometer(UV-VIS),and Hall *** the Ni contents were below 3 at.%,partial Zn2+ ions were replaced by the Ni2+ ions without forming any other phases,which enhanced the conductivity of the *** the Ni contents were above 3 at.%,Ni ions were at the interstitial sites,and Ni-related clusters and defects were able to emerge in the films,resulting in a worsening of electrical and optical properties.A ferromagnetic hysteresis with a coercive force of approximately 30 Oe was observed in the ZnNiO film with a Ni content of 3 at.% at room temperature.

A rice residual heterozygous line （RHL） carrying a heterozygous segment extending from RM111 to RM19784 on the short arm of rice chromosome 6 was selected from a RHL-derived population used previously. The resultant F2：3 population was used to detect quantitative trait loci （QTLs） for three yield traits, the number of spikelets per panicle （NSP）, the number of grains per panicle （NGP） and grain yield per plant （GY）. Two QTLs for NSP, one QTL for NGP and one QTL for GY were detected, all of which were partially dominant and had the enhancing alleles from the maternal line Zhenshan 97B. Analysis based on the genotypic groups of the markers closely linked to the two QTLs for NSP indicated that they did not interact with each other. Two F2 populations and two near isogenic line （NIL） sets segregating in two sub-regions of interval RM111-RM19784 were developed. The two QTLs for NSP were validated, of which one had major effect and was co-segregated with heading date gene Hdl, and the other had smaller effect and was located in an upper region linked to Hdl. The two regions also showed significant effects on the number of filled grain and grain yield, although the effect on the number of filled grain was less consistent.

Objective：To investigate the effect of the gap junction blocker 1-heptanol on the in vitro chondrogenic differentiation of mouse bone marrow mesenchymal stem cells（MSCs） following induction by GDF-5. Methods：MSCs were isolated from mouse bone marrow and cultured in vitro. After 3 passages cells were induced to undergo chondrogenic differentiation with recombinant human GDF-5（100 ng/ml）, with or without 1-heptanol（2.5 la mol/L）. The effect of 1-heptanol on MSCs proliferation was investigated using the MTT assay. Type II collagen mRNA and protein were examined by RT-PCR and immunocytochemistry respectively, and the sulfate glycosaminoglycan was assessed by Alcian blue dye staining. Connexin43（Cx43） protein was examined by western blotting. Results：GDF-5 induced proliferation and chondrogenic differentiation of MSCs. While 1-heptanol treatment had no effect on this proliferation, it inhibited the expression of both type II collagen mRNA and protein. The Alcian blue staining revealed that 1-heptanol also inhibited the deposition of the typical cartilage extracellular matrix promoted by recombinant GDF-5. Western blotting demonstrated that 1-heptanol had no effect on the expression of Cx43. Conclusion：These results suggest that mouse bone marrow MSCs can be differentiated into a chondrogenic phenotype by GDF- 5 administration in vitro. While the gap junction blocker, 1-heptanol, did not reduce gap junction Cx43, these intercellular communication pathways clearly played an important functional role in GDF-5-induced cartilage differentiation.
