We present an estimation of depth of anomalous bodies using normalized full gradient （NFG） of gravity anomaly. Maxima in the NFG map can locate the bodies and indicate their depth. Model calculation using a sphere and application of the NFG method to gravity anomalies over salt domes in the USA and Denmark shows effectiveness of the method. However, the accuracy of depth estimation strongly depends on the number of term N in the Fourier series used to calculate the NFG. An optimum N for the calculation can be given from a test.

Objective: To express human Vascular endothelial growth factor121(VEGF121) in insect cells. Methods: A gene construct containing VEGF was cloned in the p Fast Bac-HTA vector, followed by transformation in DH10 BAC. The recombinant bacmid was then extracted, and transfected into Sf9 insect cells. The transfected cells were harvested, and then VEGF expression was confirmed by Western blotting using specific antibodies. The tube formation assay was used for functional assessment of VEGF. Results: Our results showed that VEGF could be successfully expressed in the baculovirus system. Purified VEGF was able to stimulate in vitro tube formation of human endothelial cells. Conclusions: Results from this study demonstrated that the recombinantly-produced VEGF can be considered as a promising candidate for therapeutic purposes.

Background and Aims: Dissatisfaction with sexual relationships can influence the marital life of people and have negative psychological effects on them. Hence, the current research was conducted to evaluate the effectiveness of sexual skills training on marital satisfaction. Methods: The study design was quasiexperimental with pre-test and post-test type along with a control group. The research samples included 14 couples (28 people) who were randomly divided into experimental and control groups to evaluate the effect of sexual medicine intervention. Interventions were provided to the experimental group during 9 sessions. Control group did not receive any interventions during this time. Enrich Marital Satisfaction Questionnaire (short form) was used to collect the data. Data were analyzed using SPSS, version 19, software. Results and Conclusion: The results revealed that sexual skills training increased marital satisfaction (p<0.01). Thus, based on the results obtained and the importance of sexual skills training in increasing marital satisfaction, psychotherapists and counselors are recommended to use this intervention to reduce marital problems and increase satisfaction in couples.

关键词： sexual skills training sexual knowledge and attitude sexual satisfaction marital satisfaction

本项研究的处理工艺可以强化热轧双相(dual-phase DP)钢。为此研究了一种能达到局部强化的方法,即局部激光热处理(laser heat treatment LHT)。DP钢板以不同程度的预应变,用冷轧随后激光热处理达到整体而均匀的变形。经选择各种参数进行此项处理后,用光学显微镜(LOM)、扫描电镜(SEM)、透射电镜(TEM)、硬度测量和拉伸试验来评估热处理区的表面和横截面的显微组织,以及力学性能。结果说明用局部热处理能得到局部高强度。在较低的处理温度,这种效应可认为是烘烤强化(bake hardening BH),增加预应变和温度,从而提高局部性能。随着处理温度增加影响表面附近的初始组织。用激光局部强化DP钢开辟了一个新的领域,应用于把强化效应用到只影响感兴趣的相关区域,因此提供了节能的潜力和能设计零部件的性能。
