Discussion on key issues of carbon footprint accounting for bast fiber textiles.

Bast fiber textiles have become increasingly popular as a sustainable alternative in recent years. Although the carbon emissions of bast fiber textiles have been studied using life cycle assessment method, there is a lack of comprehensive literature analyzing and summarizing the results. This study reviews the current state of research on the carbon emissions of bast fiber textiles.

Stressing State Analysis of an Integral Abutment Curved Box-Girder Bridge Model.

This paper experimentally investigates the working behavior characteristics of an integral abutment curved box-girder (IACBG) bridge model based on the structural stressing state theory. First, the stressing state of the bridge model is represented by generalized strain energy density (GSED) values at each load and characterized by the normalized GSED sum . Then, the Mann-Kendall (M-K) criterion is adopted to detect the stressing state mutations of the bridge model from - curve in order to achieve the new definition of structural failure load.

Effect of donepezil on Hcy level in serum of Alzheimer's disease patients and correlation analysis of Hcy and dyssomnia.

Effect of donepezil on the homocysteine (Hcy) level in serum of Alzheimer's disease (AD) patients and correlation between Hcy and dyssomnia was investigated. A retrospective analysis of 124 AD patients in Zhengzhou University People's Hospital between January 2015 and October 2017 was performed, including 64 cases in the observation group and 60 cases in the control group. The control group was treated with folic acid, vitamin B12 and memantine hydrochloride tablet, and the observation group combined with donepezil on this basis, and both groups were treated for 4 months.
