The purpose of this study was to develop a protein chip technique based on receptor binding assays to measure bioavailable serum sex hormone levels (BSSHL). 224
Numerical simulation of the influences of sinker weight on the deformation and load of net of gravit
A numerical model for determining fishing net configuration and load is developed, based on the lumped masses method. The model is used to analyze the influence
The dynamic tensile test of 0.11C-0.62Si-1.65Mn TRIP steel was carried out at different strain rates and test temperatures. The results show that both temperatu
The title compound [ Ni(DMF)6]3[PMo12O40] 2 ( DMF = N, N’-dimethyllformamide ) was synthesized and structurally characterized by elemental analysis, IR, UV and

A new on-line batch process monitoring and diagnosing approach based on Fisher discriminant analysis (FDA) was proposed. This method does not need to predict th
The conversion of methanol to olefins (MTO) over the SAPO-34 catalyst in fixed-bed microreactor was studied. The effect of reaction temperatures for methanol co
In this paper a family, called the pivotal family, of distributions is considered.A pivotal family is determined by a generalized pivotal model. Analytical resu
