Laboratory Study of Geotextiles Performance on Reinforced Sandy Soil

Journal of Earth Science 2016年第6期27卷 1060-1070页

This paper presents the results of triaxial tests conducted for the investigation of the influence of geotextiles on stress-strain and volumetric change behaviour of reinforced sandy soil. Tests were carried out on loose sandy soil. The experimental program includes drained compression tests on samples reinforced with different values of both geotextiles layers （Ng） and confining pressure （σ′c）. Two methods of preparation were used： air pluviation （AP） and moist tamping （MT）. Test results show that the geotextiles induce a quasi-linear increase in the stress deviator （q） and volume contraction in the reinforced sand. Method of preparation significantly affects the shear strength; samples prepared by the air pluviation method and mobilized deviator stresses are significantly higher than those prepared by moist tamping method. Geotextiles restrict the dilation of reinforced sandy soil and consequently the contraction increases. The mobilized friction angle increases with increasing number of layers and decreases with increasing initial confining pressure. Samples prepared by moist tamping present mobilized friction angles significantly lower than those prepared by air pluviation method. For samples prepared by the air pluviation method, the secant modulus at ε1=1% and 5% decreases with increasing geotextile layers; those prepared by the moist tamping method, secant modulus at ε1=1% and 5% increases with increasing number of geotextile layer sand confining pressure. From 10% axial strain, secant modulus increases with increasing inclusions of geotextile layers.

Case Reports in Clinical Medicine 2024年第4期13卷 87-94页

作者： Ketevan Kapanadze Elene Shengelia Keti Solomnishvili Ahmed Saleh abdelkader Maha Kassem Internal Medicine and Intensive Therapy Department Tbilisi Central Hospital Tbilisi Georgia Internal Medicine Residency Program Tbilisi State Medical University Tbilisi Georgia School of Medicine New Vision University Tbilisi Georgia

Takotsubo cardiomyopathy is a heart condition that is widely known to be caused by stress. It presents with symptoms that are similar to a myocardial infarction even though the coronary arteries are clear. This case report details the clinical characteristics, diagnostic assessment, and management plan of a 55-year-old male patient with a past medical history of alcoholism who arrived at the emergency department with the typical symptoms of acute pancreatitis. The case demonstrates the progression of Takotsubo cardiomyopathy, which was triggered by acute pancreatitis in the context of alcoholism, and underlines the significance of early detection and management to enhance the patient’s outcomes.

Background: Occupational dermatitis is considered as the second most common occupational disease. It accounts for 25% of all lost workdays. Several international studies reported a prevalence of occupational dermatitis in healthcare workers between 17% and 55%. This study aims to identify factors that affect the professional outcome of nurses suffering from occupational dermatitis. Methods: This was a multicenter cross-sectional study concerning nurses declared having occupational dermatitis in the central region of Tunisia. A synoptic sheet related to socio-professional and administrative data was completed. A self-administered Questionnaire going over medical and occupational characteristics was completed during a direct interview. Results: The study involved forty nurses working in four public hospitals in the center of Tunisia. Only 37 workers were included in the study. A professional reclassification was introduced among 19 workers (51% of study population). Work-station adaptation was requested in 14 cases (38%). Exposure to allergens in the workplace was eliminated in 20 cases. Two study participants were transferred to other departments (5.4%) and three people retired (8.1%). A statistically significant association was found between professional reclassification and a history of allergic manifestations (p = 0.003). Similarly, a significant association was found between professional reclassification and the allergic agent (p = 0.014). Workstation layout was significantly associated with a history of allergic manifestations (p = 0.039), the palm hand location (p = 0.04), professional eviction (p Conclusion: This study identified the main factors influencing the occupational outcome of nurses suffering from occupational dermatitis. This outcome depended on a history of atopy (especially allergic rhinitis) and sensitization to allergens (thiuram mix).
