HighlightsDe Garengeot’s hernias constitute an extremely rare condition associated with emergency surgery.Suspicion and experience are crucial for correct management, as no therapeutic or diagnosis consensus has been reached.A single surgical procedure can be performed to treat both pathologies; incarcerated hernia and strangulated appendix.An open preperitoneal approach permits correct visualization of the sac contents and permits appendectomy and hernia repair.When a complication is found, such as local perforation or abscess, a two-step abdominal wall repair should be considered.
Despite the growth of the offshore wind industry, there are currently doubts relating to the design of wind facilities in the sea. This paper expounds current, already identified structural uncertainties: problems for soil characterization and transition piece (TP) design. This document also introduces new doubts or issues to be researched in the near future in this field (wave theory, scour process, wave load actions, scale difficulty, etc.), not as yet identified due to the scarce experience in the offshore wind industry. With this in mind, technical offshore wind standards related to foundation design have been reviewed.
Conventional seismic analysis of gravity dams assumes that the behaviour of the dam-water-soil system can be represented using a 2-D model since dam vertical contraction joints between blocks allow them to vibrate independently from each other. The 2-D model assumes the reservoir to be infinite and of constant width, which is not true for certain types of reservoirs. In this paper, a boundary element method (BEM) model in the frequency domain is used to investigate the influence of the reservoir geometry on the hydrodynamic dam response. Important conceptual conclusions about the dam-reservoir system behaviour are obtained using this model. The results show that the reservoir shape influences the seismic response of the dam, making it necessary to account for 3-D effects in order to obtain accurate results. In particular, the 3-D pressure and displacement responses can be substantially larger than those computed with the 2-D model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
