Seismic effects on reinforcement load and lateral deformation of geosynthetic-reinforced soil walls

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 4, Pages 1001-1015 doi: 10.1007/s11709-021-0734-8

Abstract: Current design methods for the internal stability of geosynthetic-reinforced soil (GRS) walls postulate seismic forces as inertial forces, leading to pseudo-static analyses based on active earth pressure theory, which yields unconservative reinforcement loads required for seismic stability. Most seismic analyses are limited to the determination of maximum reinforcement strength. This study aimed to calculate the distribution of the reinforcement load and connection strength required for each layer of the seismic GRS wall. Using the top-down procedure involves all of the possible failure surfaces for the seismic analyses of the GRS wall and then obtains the reinforcement load distribution for the limit state. The distributions are used to determine the required connection strength and to approximately assess the facing lateral deformation. For sufficient pullout resistance to be provided by each reinforcement, the maximum required tensile resistance is identical to the results based on the Mononobe–Okabe method. However, short reinforcement results in greater tensile resistances in the mid and lower layers as evinced by compound failure frequently occurring in GRS walls during an earthquake. Parametric studies involving backfill friction angle, reinforcement length, vertical seismic acceleration, and secondary reinforcement are conducted to investigate seismic impacts on the stability and lateral deformation of GRS walls.

Higher-order mode effects on the seismic performance of tall piers

Zhongguo GUAN, Jianzhong LI, Yan XU, Hao LU

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 4, Pages 496-502 doi: 10.1007/s11709-011-0131-9

Abstract: A comprehensive analysis was conducted to investigate the seismic performance of a typical tall bridge pier through incremental dynamical analysis (IDA). The effect of higher-order modes was studied specifically. The results showed that higher-order modes significantly contributed to the structural seismic response and should not be neglected. Including these modes resulted in an additional hinge midway up the pier. No plastic hinge would occur at this location for conventional bridge piers. Higher-order modes also led to an out-of-phase response between the hinge rotation at the pier bottom and the displacement at the top. This means that the displacement-based seismic design method cannot correctly predict the mechanical state of the critical hinge and therefore is not suitable for use in the seismic design of tall piers. Mistakenly using the displacement-based seismic design method for tall piers may result in a seriously unsafe condition.

Beneficial effects of preventive cholecystectomy in patients with hepatic cancer

LIU Anzhong, LI Jun, HUA Huwei

Frontiers of Medicine 2008, Volume 2, Issue 2, Pages 139-142 doi: 10.1007/s11684-008-0026-x

Abstract: There is no conclusive answer to the question whether excising gall bladder is helpful to the patient with hepatic cancer. The survival rate of patients with hepatic cancer for more than two years has been increased, and the incidence of complications of cholecystitis and gall stone are relatively higher among these patients, which may seriously complicate treatment of advanced hepatic cancer and decrease quality of life. The researchers conducted a prospective clinical investigation from 2002 to 2006 to assess the clinical significance of preventive cholecystectomy in patients with hepatic cancer. One hundred and eighteen cases of postoperative patients with hepatic cancer, who survived for more than two years, were followed up. Based on whether cholecystectomy was performed, the patients were divided into two groups including 48 cases with cholecystectomy and 70 cases with cholecyst reserved. The two-year morbidity of gall stone and morbidity of pain in the right upper abdomen of cholecyst reservation group were 54.29% and 68.57%, respectively, obviously higher than 0.00% and 20.83% of cholecystectomy group. Mainly for those treated with transcatheter arterial chemo-embolization, the morbidity of gall stone was 86.67% ( < 0.01). Therefore, preventive cholecystectomy is strongly recommended during hepatectomy to decrease the incidence of chronic cholecystitis and gall stone, especially for those whose chemotherapy and embolization will be carried out through hepatic artery and portal vein.

Bile acids and their effects on diabetes

Cynthia Rajani, Wei Jia

Frontiers of Medicine 2018, Volume 12, Issue 6, Pages 608-623 doi: 10.1007/s11684-018-0644-x

Abstract: Diabetes is a widespread, rapidly increasing metabolic disease that is driven by hyperglycemia. Early glycemic control is of primary importance to avoid vascular complications including development of retinal disorders leading to blindness, end-stage renal disease, and accelerated atherosclerosis with a higher risk of myocardial infarction, stroke and limb amputations. Even after hyperglycemia has been brought under control, “metabolic memory,” a cluster of irreversible metabolic changes that allow diabetes to progress, may persist depending on the duration of hyperglycemia. Manipulation of bile acid (BA) receptors and the BA pool have been shown to be useful in establishing glycemic control in diabetes due to their ability to regulate energy metabolism by binding and activating nuclear transcription factors such as farnesoid X receptor (FXR) in liver and intestine as well as the G-protein coupled receptor, TGR5, in enteroendocrine cells and pancreatic -cells. The downstream targets of BA activated FXR, FGF15/21, are also important for glucose/insulin homeostasis. In this review we will discuss the effect of BAs on glucose and lipid metabolism and explore recent research on establishing glycemic control in diabetes through the manipulation of BAs and their receptors in the liver, intestine and pancreas, alteration of the enterohepatic circulation, bariatric surgery and alignment of circadian rhythms.

Effects of exercise therapy on bone mineral density in early postmenopausal women: a controlled trial

Shilin DENG MD ,

Frontiers of Medicine 2009, Volume 3, Issue 3, Pages 323-329 doi: 10.1007/s11684-009-0061-2

Abstract: The purpose of this article is to determine the effect of a well-designed combined aerobic, resistance, and extension exercise program on bone mineral density (BMD) in postmenopausal women. The population comprised 45 postmenopausal women, who exercised over 12months (exercise group), and 36 women who served as a non-training control group. BMD of the hip, and lumbar spine was measured at the baseline and 12th month. Repeated measurement analysis of variance and nonparametric test were utilized to compare differences between the exercise group and controls. Thirty-six out of 45 persons in the exercise group and 36 controls completed the study. Average compliance was 82.2% for the whole exercise group at the 12th month. All the subjects had decreased BMD, but the rate of bone loss was lower in the exercise group than in the control group at the L4 and hip. Although the exercise program in this study may probably reduce the rate of bone loss in weight-bearing skeletal sites, we do not suggest the exercise by itself be viewed as prevention or treatment for osteoporosis. Further, the exact dose-response relationship of exercise and bone mass in early postmenopause is not clear.
