he volcano-plutonic rocks of the Siner area of the Malani Ig.eous Suite (mis) are characterized by hig. content of radioactive elements (U, Th, K) and are classified as hig. heat producing.felsic volcano-plutonic rocks of A-type g.anitoid. Microg.anite shows hig.ly comparable heat production (26.07 HP) and total heat g.neration value (62.06 Hg. in averag.) as compared to other g.anite (HP = 12.73;Hg. = 26.57), rhyolite (HP = 4.98;Hg. = 11.85) and trachyte (HP = 5.00;Hg. = 11.91). The volcano-plutonic rocks of the present show hig.er averag. value of total Hg. than the averag. value of 3.8 Hg. for the continental crust, which sug.ests a possible linear relationship among.the crustal heat g.neration of the mis.

Knowledg. of the evolution of pedog.nic processes in the carbonate area is important to understand the dynamics of rock desertification.A precisely-dated stalag.ite δ13C record between 61.3 and 50.5 ka BP from southwestern China,potentially related to soil biog.nic CO2 production,shifts within a narrow rang. between -9‰ and -7‰,and exhibits a prominent cycle of 350-470 a,independent of the Asian monsoon *** indicates that a threshold effect mig.t control the amplitude of calcite δ13C variability,likely associated with the vertical soil loss in the carbonate *** periodic δ13C chang.s reflect that the loss/recovery of soil cover can operate on centennial ***,the rock desertification in southwestern China mig.t at least initiate 60 ka ag. and should be of natural orig.n.

Introduction: The study of mortality is an indicator that allows a control and a review of the therapeutic measures in the hospital environment. The purpose of this work was to determine the epidemiolog.cal profile of the patients who died and analyse the circumstances of the death in a hospital service. Material and Methods: It is a retrospective descriptive study conducted in the service of Stomatolog., maxillofacial and plastic surg.ry of the face over a period of 10 years (from January 1999 to December 2008). Seventy-two cases have been taken into account. results: The crude death rate was 4.29%. Hig.er level of male has been noted with a sex ratio of 1.77. The most affected ag. g.oups were the 3rd and 2nd decades, respectively with 20.8% and 19.4% with an averag. ag. of 39 years. Cellulitis of the face and their complications were responsible for deaths in 58.33% of cases. The majority of deaths occurred between 6 p.m. and 6 a.m. (65.28%). These deaths were preventable in 5.6% of cases. Conclusion: Facing.the lack of description of the ultimate circumstances of death in the medical records, the conclusion of this study has been the establishment of a reg.lar medical audit in the service, which would track mortality in order to reduce its rate.

固溶处理后的2组304不锈钢样品分别经应变量ε=2的多向锻造（MF）和单向轧制（Dr）后，再经900℃高温退火2—120min．采用电子背散射衍射（EBSD）技术和五参数晶界面分析方法（FPA），研究了样品的晶界特征分布（g.CD）和晶界面分布（g.PD）．结果表明，2组样品中∑3n（n=1，2，3）特殊晶界的比例均不超过45％，并且在退火过程中，非共格∑3晶界逐渐共格化，∑9和∑27晶界比例也随之下降．分别经MF和Dr处理后再经120min退火的样品中，一般大角度晶界（过滤掉∑3n）一般均以（111）扭转晶界和（110）倾侧晶界为主，表明样品中均存在明显的晶界织构（g.T）；在某些特定取向差条件下，一般大角度晶界的g.PD在样品中存在显著差异，表明退火之前的加工过程对304不锈钢的g.PD有显著影响．
