| 1 | Examining the effect of adverse geological conditions on jamming of a single shielded TBM in Uluabat tunnel using numerical modeling显示文摘Severe shield jamming events have been reported during excavation of Uluabat tunnel through adverse geological conditions, which resulted in several stoppages at advancing a single shielded tunnel boring machine(TBM). To study the jamming mechanism, three-dimensional(3D) simulation of the machine and surrounding ground was implemented using the finite difference code FLAC3D. Numerical analyses were performed for three sections along the tunnel with a higher risk for entrapment due to the combination of overburden and geological conditions. The computational results including longitudinal displacement contours and ground pressure profiles around the shield allow a better understanding of ground behavior within the excavation. Furthermore, they allow realistically assessing the impact of adverse geological conditions on shield jamming. The calculated thrust forces, which are required to move the machine forward, are in good agreement with field observations and measurements. It also proves that the numerical analysis can effectively be used for evaluating the effect of adverse geological environment on TBM entrapments and can be applied to prediction of loads on the shield and preestimating of the required thrust force during excavation through adverse ground conditions. | Rohola Hasanpour Jürgen Schmitt Yilmaz Ozcelik Jamal Rostami | 2017 | Journal of Rock Mechanics and Geotechnical Engineering2017，9，6： | 8 |

| 8 | Progressive exhaustion:A qualitative study on the experiences of Iranian family caregivers regarding patients undergoing hemodialysis显示文摘Objective:The aim of this study was to explore the burden of care for patients undergoing hemodialysis from the experiences of family caregivers.Methods:In this qualitative study,a content analysis approach was used for data collection and analysis.Participants were 16 family caregivers selected through purposive sampling from four medical education centers affiliated with Ahvaz Jundishapur University of Medical Sciences,Iran.Semi-structured interviews were held to collect data.Results:Four categories were developed as follows:‘care challenges’,‘psychological vulnerabilities’,‘the chronic nature of care’and“care in the shade”.The categories led to the development of the main theme of‘progressive exhaustion’experienced by the family caregivers during the provision of care to patients undergoing hemodialysis.Conclusion:Family caregivers have a significant role in the process of patient care,and this role leads them to progressive exhaustion;therefore,the overall health of the caregivers should be taken into account and more attention should be paid to their quality of life,social welfare,and satisfaction level. | Shahriar Salehitali Fazlollah Ahmadi Ali Hasanpour Dehkordi Kobra Noorian Malek Fereidooni-Moghadam Kouroush Zarea | 2018 | International Journal of Nursing Sciences2018，5，2： | 1 |
