一种新型高价锰取代的多金属氧酸盐合成、结构及性质研究

在含有MnⅡ的夹心型多金属氧酸盐水溶液中加入强氧化剂KMnO4,制得一种新型的含有MnⅢ的多金属氧酸盐K5Na3[{MnⅢ(H2O)}2(WO)(H2O) (AsW9O33)2]·18H2O (KNa-1).该化合物的多阴离子结构是基于2个B-α-[AsW9]三缺位Keggin型构筑单元,中间夹着2个{MnⅢ(H2O)}和1个{WⅥO}片段而构成的夹心式构型.对KNa-1进行了变温磁化率测定并采用双核MnⅢ簇为模型进行了拟合,并对该化合物进行了电化学分析.结果表明:KNa-1 中的2个MnⅢ中心存在弱的反铁磁相互作用;化合物中的MnⅢ离子具有不可逆的氧化还原过程.     

Kinanthropometry Study of the Physique of Hong Kong and the Interior of China Correctional Services Recruits

In this paper,the physique of the Hong Kong Correc-tional Services recruits were identified and reported.Kinanthropometry has been applied in the study of Olympic athletes and researchers concluded that specificsports were correlated with a specific type of physique.Athletes involved in the same sports have a similar phys-ique as well as body shape.Gold medal winners could beidentified by their specific type of body shape.And ath-letes in different sport have different and specific bodyshape.Hence,by applying kinanthropometry study,people in different occupations could be identified by their specific body shape and physique.The finalisedbody shape can be used as reference in the vetting stan-dards.The somatotyping and anthropometric input canbe used to improve the uniform sizing system.     

Anthropometric Study of the Physique of Hong Kong-Chinese Fire Services Recruits to Streamline the Sizing System

This research applies the principles of anthropometrics to improve existing size charts together with somatotyping techniques to define the physique of the Hong Kong-Chinese Fire Services recruits. The research results proved that age does not correspond with either body measurements or somatotype components. The results of the study demonstrates that the somatotype component (i. e., endomorphy, mesomorphy and ectomorphy) has low to moderate correlation with body girth and body length measurements.     

A role for MLH3 in hereditary nonpolyposis colorectal cancer

We investigated a possible role of the mismatch-repair gene MLH3 in hereditary nonpolyposis colorectal cancer by scanning for mutations in 39 HNPCC families and in 288 patients suspected of having HNPCC. We identified ten different germline MLH3 variants, one frameshift and nine missense mutations, in 12 patients suspected of HNPCC. Three of the 12 also carried a mutation in MSH6.
