| 1 | Direct and relaxation methods for soil-structure interaction due to tunneling显示文摘This paper deals with the problem of tunneling effects on existing buildings. The direct solution,using the condensation method,is presented. This method allows the structural and geotechnical engineers to treat the problem separately and then assemble a relatively small matrix that can be solved directly,even within a spreadsheet. There are certain concerns that the resultant matrix may be ill-conditioned when the structure is very stiff. This paper suggests an alternative method that essentially relaxes the system from an infinitely rigid structure solution. As such,it does not encounter the problems associated with stiff systems. The two methods are evaluated for an example problem of tunneling below a framed structure. It is found that while the direct method may fail to predict reasonable values when the structure is extremely rigid,the alternative method is stable. The relaxation method can therefore be used in cases where there are concerns about the reliability of a direct solution. | Assaf KLAR Itai ELKAYAM | 2010 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2010，11，1： | 3 |
| 2 | Nutritional and health benefits of semi-elemental diets: A comprehensive summary of the literature显示文摘AIM:To critically review and summarize the literature on nutritional and health outcomes of semi-elemental formulations on various nutritionally vulnerable patient populations who are unable to achieve adequate nutrition from standard oral diets.METHODS:We conducted a comprehensive literature search of Pubmed and Embase databases.We manually screened articles that examined nutritional and health outcomes(e.g.,growth,disease activity,gastrointestinal impairment,mortality,and economic impact)among various patient groups receiving semi-elemental diets.This review focused on full-text articles of randomized controlled clinical trials and other intervention studies,but pertinent abstracts and case studies were also included.Results pertaining primarily to tolerance,digestion,and absorption were summarized for each patient population in this systematic review.RESULTS:Results pertaining primarily to tolerance,digestion,and absorption were summarized for each patient population.The efficacy of semi-elemental whey hydrolyzed protein(WHP)diet have been reported in various nutritionally high risk patient populations including-Crohn’s disease,short bowel syndrome,acute and chronic pancreatitis,cerebral palsy,cystic fibrosis,cerebrovascular accidents,human immunodeficiency virus,critically ill,and geriatrics.Collectively,the evidence from the medical literature indicates that feeding with a semi-elemental diet performs as well or better than parenteral or amino acid based diets in terms of toler-ance,digestion,and nutrient assimilation measures across various disease conditions.CONCLUSION:Based on this comprehensive review of the literature,patient populations who have difficulty digesting or absorbing standard diets may be able to achieve improved health and nutritional outcomes through the use of semi-elemental WHP diets. | Dominik D Alexander Lauren C Bylsma Laura Elkayam Douglas L Nguyen | 2016 | World Journal of Gastrointestinal Pharmacology and Therapeutics2016，7，2： | 3 |
| 3 | A hardening load transfer function for rock bolts and its calibration using distributed fiber optic sensing显示文摘Confinement of rock bolts by the surrounding rock formation has long been recognized as a positive contributor to the pull-out behavior,yet only a few experimental works and analytical models have been reported,most of which are based on the global rock bolt response evaluated in pull-out tests.This paper presents a laboratory experimental setup aiming to capture the rock formation effect,while using distributed fiber optic sensing to quantify the effect of the confinement and the reinforcement pull-out behavior on a more local level.It is shown that the behavior along the sample itself varies,with certain points exhibiting stress drops with crack formation.Some edge effects related to the kinematic freedom of the grout to dilate are also observed.Regardless,it was found that the mid-level response is quite similar to the average response along the sample.The ability to characterize the variation of the response along the sample is one of the many advantages high-resolution fiber optic sensing allows in such investigations.The paper also offers a plasticity-based hardening load transfer function,representing a'slice'of the anchor.The paper describes in detail the development of the model and the calibration/determination of its parameters.The suggested model captures well the coupled behavior in which the pull-out process leads to an increase in the confining stress due to dilative behavior. | Assaf Klar Ori Nissim Itai Elkayam | 2023 | Journal of Rock Mechanics and Geotechnical Engineering2023，15，11： | 2 |
