Research ArticleOpen accessIn the author namesEffects of Different Drying Methods on Antioxidant Activity of Polysaccharides from Antler MushroomBing Xu, Yi Dai, Shiyu Xu et al.In this study, three polysaccharides (AMP-H, AMP-V and AMP-F) were obtained from polysaccharides of Antler Mushroom (AMP) by hot air drying, vacuum drying and freeze drying, respectively. The chemical composition and antioxidant capacity of AMP-H, AMP-V and AMP-F were investigated. The results showed that the AMP was an acidic polysaccharide containing a small amount of protein. The drying method did … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 3 · 15 Jul 2021 · 7,243 accessesView PDFCite
Research ArticleOpen accessIn the author namesFluid-Solid Coupling Analysis on Evolution of In-Situ Stress Field by Water Injection in OilfieldJianjun Liu, Yongxiang Zheng, Bohu Zhang et al.Water injection in oilfield may break initial balance of reservoir and lead to re-distribute of stress and deformation of strata. For further research of the evolution characteristics of in-situ field by water injection, the influence on reservoir by water injection was analyzed and different variables were set to study the effects of depth, injection-withdraw ratio and elastic modulus on strain … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 6 May 2017 · 8,061 accessesView PDFCite
Research ArticleOpen accessIn the author namesOptimization of Raw Materials for Preparation of Transparent Soil Based on Analytic Hierarchy ProcessJianjun Liu, Yao Wang, Rui Song, Min YeThe application of man-made transparent soil has greatly contributed to the development of the visual research in physical model test. Comparing to the traditional model test, the transparent soil has advantages with respect to transparency, visualization, lower cost and utility et al. However, the transparency of material itself seriously restricted the effect of the results during the model text. This … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 1 Mar 2017 · 7,266 accessesView PDFCite
Research ArticleOpen accessIn the author namesNumerical Study on the Influence of Fault on the Seepage and Stress Field of FormationYongxiang Zheng, Jianjun Liu, Bohu Zhang, Yue SunIn the process of water injection in oil field, the fault will affect the seepage field and stress field of the formation, which leads to the deformation and destruction of the formation. Therefore, more casing damage wells are found around the fault. In order to study the influence of fault on the formation in the process of water injection, a … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 9 Feb 2017 · 7,344 accessesView PDFCite
