Stability of the embankment of fine sand reinforced with geosynthetic materials

This research paper validates the significance of an assimilated attitude when choosing the design of the subgrade of railways constructed from fine sands in difficult engineering and geological conditions in the desert and steppe territories of Uzbekistan to ensure their sustainability with modern technologies and materials. The analysis of the results obtained in the calculations of the stability coefficient of the design structure of the embankment. The characteristics of the embankment soils correspond to the design data of the object "Removal of the existing railway section Dunguluk-Burgutli-Misken from the flood zone of the Shurbulak reservoir" The results of the calculations performed by the method of G. M. Shakhunyants, as well as the software "GEO 5" and "Plaxis 2D" show that the structure of the embankment with a height of more than 6 meters does not provide the required standard coefficient of stability. Complete warps of the embankment and graphs of changes in the stability coefficient of the design structure of the embankment, and with the laying of geotextiles as reinforcement of the pattern of the subgrade of railways, are given. Beneficial solutions to increase the stability coefficient of the embankment from fine sands are proposed, and the efficiency of using geosynthetic materials as a reinforcement of the pattern of the subgrade is substantiated. Theoretical calculations and analysis of prevailing embankment structures confirm the feasibility of reinforcing the structure of the subgrade erected from fine sands on the railway lines of Uzbekistan.

Effect of Evolocumab on Vulnerable Coronary Plaques: A Serial Coronary Computed Tomography Angiography Study

This study investigated the effects of evolocumab on vulnerable coronary plaques and factors associated with the change in stability and size of plaques in patients taking statins. Vulnerable coronary plaques were defined using coronary computed tomography (CT) angiography as having a density of <50 HU within the region of interest and a remodeling index ≥1.1. The changes in minimum CT density, remodeling index, and percent stenosis of vulnerable coronary plaques after six months of evolocumab administration were retrospectively analyzed in 136 vulnerable coronary plaques from 98 patients (68 men and 30 women; mean age: 72.9 ± 8.7 years) treated with a statin. The administration of evolocumab significantly increased the minimum CT density (39.1 ± 8.1 HU to 84.9 ± 31.4 HU, p < 0.001), reduced the remodeling index (1.29 ± 0.11 to 1.19 ± 0.10, p < 0.001), and decreased the percent stenosis (27.0 ± 10.4% to 21.2 ± 9.8%, p < 0.001). Multiple linear regression analysis revealed that baseline percent stenosis (standard coefficient (β) = −0.391, p = 0.002) independently correlated with the change in minimum CT density, whereas the baseline remodeling index (β = −0.368, p < 0.001) independently correlated with a change in the remodeling index. Evolocumab stabilized vulnerable coronary plaques and reduced their size. These results suggest that evolocumab protects against coronary artery disease progression in patients taking statins.

Social media and hotel e-marketing in Iran: The case of Parsian International Hotels

With a quantitative study, this research has aimed to investigate the role of social media in Iranian hotels’ electronic marketing. A questionnaire technique was used on a sample of 140 marketers who work in the Parsian International Hotels’ marketing department. For data evaluation an SPSS program was used. Kolmogorov-Smirnov, Cochran, Regression, Non-standardized coefficients and Standard coefficient tests were carried out. Based on the findings, we can state that social media are still not an important marketing tool for Iranian hotels. Facebook and YouTube are the media which are most used for marketing purposes as videos and photos can be used on these sites more than others. The results show that the marketing abilities of Parsian Hotels improve with the increasing use of social media, but the hotel marketing sector has failed to fully utilize internet opportunity as a marketing tool.
