As well known there exist complex interaction between the trace elements, and the trace elements and other substances, so the trace element research must be involved to the com-prehensive effect of multifactors, other than single element. We determined the contents of fifteen trace elements in serum from thirty patients with liver cancer and thirty healthy adults by ICP-AES analysis. The obtained data were analysed statistically by not only routine statistical test bat also multi-variate discrimination analysis, multi-variate stepwise regression and non-linear mapping algorithm. It is hoped that it can provide some valuable informations for investigation on relationship betwecn trace elements and cancer.展开更多

However, their composition and standard by and large throughout the year may not remain same due to obvious reasons. Moreover, there is no mention of locally produced feed particularly in the north eastern part of India. The major objective of this study was to prepare mesh feed E1 with the available ingredients as well as their effect were compared with that of the two commercially available feed Amrit and Godrej (E2 and E3) in terms of Crude protein, fats and element composition. The findings showed that the protein content (240 g/kg) and fats (105 g/kg) in the breast muscle of female was higher in the E3 received against the broiler chicken received local feed. Element analysis of the E1, E2 and E3 depicted significantly higher value of Ca, K, Cu Zn and Se against the commercial feed. Other elements like Mg, Na, Fe, P, and Mn showed no variation while compared E1, E2 and E3 together. Thus the present findings suggest that the local feed E1 could be accepted at per with that of the commercial feed for poultry.展开更多

The migration and enrichment of geochemical element in the continuous fine-grained sediments in the basin recorded the paleosalinity and the paleodepth. The changes of paleosalinity and paleodepth indicate the sea(lake) level relative change in every period of Late Triassic-Middle Jurassic in southwestern Fujian. The relative change curve of sea(lake) level in southwestern Fujian is established based on the m value(m=100×w(MgO)/w(Al2 O3)) and the ratios of w(B)/w(Ga), w(Sr)/w(Ba) and w(Ca)/w(Mg). The curve indicates that level I sea-level relative change in southwestern Fujian is composed of the transgression in Late Triassic-Early Jurassic and the regression in the late period of Early Jurassic-Middle Jurassic. The level III sea-level relative change is frequent, which is composed by the lake level descent lake level rise lake level descent of Wenbin Shan formation in Late Triassic, the regression transgression regression of Lishan formation in Early Jurassic and the lake level rise lake level descent-lake level rise lake level descent of Zhangping formation in Middle Jurassic. The transgression regression cycle in southwestern Fujian is significantly controlled by the sea-level change in the north of South China Sea. The relative change curve trends of the level I sea-level in the north of South China Sea and the one in southwestern Fujian are the same. The maximum transgressions both occur in Early Jurassic. The level III sea-level curve reflects the fluctuation of a transgression and two regressions in the early period of Early Jurassic.展开更多

Comparison of the design provisions of the GB 50011-2010 code and those of the American code ACI 318-14 indicates a possible deficiency in the T-shaped wall design provisions in GB 50011-2010. A case study of a typical T-shaped wall designed in accordance with GB 50011-2010 also indicates the insufficient extent of the boundary element at the non-flange end and overly conservative design of the flange end boundary element. Improved designs for special boundary elements ofT-shaped walls are developed using a displacement-based method. The proposed design formulas produce a longer boundary element at the non-flange end and a shorter boundary element at the flange end, relative to those of the GB 50011-2010 provisions. Extensive numerical analysis indicates that T-shaped walls designed using the proposed formulas develop inelastic drift of 0.01 for both cases of the flange in compression and in tension.展开更多
