Objective： To evaluate the relation between argyrophilic nucleolar organizer region （AgNOR）-associated proteins and clinicopathological parameters and survival in non-small-cell lung cancer （NSCLC）. Methods： A total of 207 surgical specimens diagnosed as NSCLC were included in this study. Double-staining procedures were performed using antigen Ki-67 （clone MIB-1） and silver nitrate by immunohistochemical and AgNOR-staining methods. Results： The AgNOR area in MIB-l-positive cells of NSCLC is related to clinicopathological parameters under the TNM （tumor, node, and metastasis） system. The survival of patients with small AgNOR area in MIB-1-positive cells is better than that of patients with large AgNOR area. Molecular, biological （AgNOR area in MIB-l-positive cells）, and clinicopathological （greatest tumor dimension, metastases to regional lymph nodes, histology, and differentiation） parameters are independent prognostic factors of ***： The AgNOR area in MIB- 1-positive cells is related to clinicopathological parameters and survival in NSCLC.

The paper describes a mathematical model of the stress-strain state of polymer composite materials in the pultrusion process of large-sized products. The influence of the pull speed on the stress-strain state of the products is investigated. To determine the maximum possible pull speed series of solutions at different pull speeds are obtained. Depending on the maximum strain in the cross section of the rod determined the optimal value of pulling speed.

There are considered rule-based intelligent systems using fuzzy inference. Comparative analysis of different approaches and algorithms of making decisions on the base of fuzzy logic is given. Using of the parallel calculations can reduce the time of making decision in case of large-scale systems. Effectiveness of parallel calculations depends on the grouping of the rules and variables. Building of the graph of the dependence of the rules and the graph of dependence of the linguistic variables are suggested. On the base of the developed groups of rules and defuzzification of the linguistic variables we suggest to reduce the time of making decision and therefore to increase the effectiveness of the decision making with using of parallel calculations for each group.

The results of the tests for a friction pair “a cylindrical specimen made of 0.45% carbon steel—a counter specimen-liner made of polytetrafluoroethyleneF4-B” during sliding friction are presented. The test results at different levels of contact load are analyzed using the Archard’s equation and are presented as a friction fatigue curve. The concept of the frictional stress intensity factor during sliding friction is introduced, and an expression that relates the wear rate to this factor and is close in shape to the Paris equation in fracture mechanics is proposed.

短路过渡CO2气体保护焊由于低成本、高效率、便于实现全位置焊接,广泛应用在工业制造领域,但是在焊接过程中,特别是在较高的焊接电流下,存在许多诸如飞溅,成形差,过渡过程不稳定等问题.文中提出了一种通过施加同步磁场来改善焊接中存在的问题的新方法.研究了不同类型的燃弧段同步磁场对焊接过程的影响.用激光作为背光,采用高速摄像系统拍摄焊接过程,观察熔滴过渡过程,计算熔滴的大小和过渡频率等.结果表明,在纵向同步磁场的作用下,可以有效地减少燃弧时间;施加同步磁场后,熔滴过渡频率范围都得到不同程度的缩小,熔滴过渡过程更稳定,并且在纵向磁场Im(LMF)=200 A时,熔滴的过渡频率大幅增加;磁场作用下,带尖角的熔滴变为圆润无尖角的球形或椭球的熔滴,熔滴的尺寸减小.
