Jointing structure is considered in most of the rock mass classification systems and it takes a great weight in those rock mass classification ***,the rock mass classification systems take different parameters for characterizing jointing structure and most rock engineering is carried out using various descriptions.A general jointing structure characterization method is of great significance for site selection,repository design and performance assessment for high-level radioactive waste *** paper concentrates on a common approach to jointing structure characterization and the results for Beishan area,Gansu province,the preselected area of china’s deep geological disposal of high-level radioactive waste.A synthesis index,JsR(Jointing structure Rating),is developed to characterize the jointing structure of rock *** main principle in the development of JsR is concentrated on the cleavage of rock mass by joints regardless of this cleavage may reduce the strength or increase the permeability of rock *** is the combination of joint den{2.,joint size and joint set *** may serve as a general index which can be used to evaluate both the block size of rock mass and the connectivity of joints *** main joints characterization such as orientation,joint set number,mean trace length and midpoint den{2. is evaluated after detailed field joint survey in Beishan *** on JsR and joints statistical description,jointing structure classification for the sections of Beishan area is *** results provide a global vision of the jointing structure in Beishan area and provide a basis for site selection and preliminary near-field performance assessment.

Luoshi Road, wuhan 43.070, china JING-KUN GUO shanghai Institute of Ceramics, Chinese Academy of science, 12.5 Dingxi Road, shanghai 2.0050, china

Ni-YsZ and Ni-Co-YsZ cermets were fabricated by hot - press - sintering from nanocomposite powders. The structure, morphology, relative density, hardness, specific heat capacity and thennal conductivity were measured Results show that the crystalline grains are much homogeneous. Their size distribution is quite narrow and between 0.2.- 0.4(?) m (2.0 - 400 nm). The Ni - Co - YsZ cermet reaches a maximum relative density (96.2.) at 1350 ·and a maximum Rockwell hardness (70.5) at 1400 ·. The specific heat capacity of Ni- YsZ cermet is larger than that of Ni - Co - YsZ cermet The thermal conductivity of Ni - YsZ cermet is smaller than that of Ni -Co-YsZ cermet.

Ribosome-inactivating proteins (RIPs) are a group of toxic proteins that can specifically act on the universally conserved sarcin/ricin domain (s/R domain) of the largest RNA in ribosome and thus irreversibly inactivate ribosome for protein synthesis. Cinnamomin is a multifunctional type II RIP isolated in our {2. from the mature seeds of the camphor tree. This protein has been extensively studied with regard to its purification, characteristics, structure and function, genetic expression, enzymatic mechanism, physiological role in seed cell and toxicity to cancer cells and insect larvae. The research results of cinnamomin obtained in our {2. are summarized in this review. Understanding of cinnamomin and the relative new proteins will help expand our knowledge of RIPs and may accelerate theoretical study and the development of their potential applications.
