The authors report a case of myiasis of the middle ear caused by Wohlfartia magnifica Schiner (Diptera: Sarcophagidae). The entomological aspects, the clinical epidemiological characteristics and the therapeutic solutions of this disease are evaluated. In particular, they underline the rarity of myiasis both because of the aetiologic agent and the anatomical site. The therapeutic aspects are also reported and discussed.
Although still little used in practice, the non-linear time-history (NlTH) analysis is the most powerful method to design new earthquake-resistant buildings. This kind of analysis may even help the designer to assess the seismic performance of existing buildings and suitably plan their retrofit. With reference to a pre-seismic-code r/c building and to a suite of Italian spectrum-consistent earthquakes, the paper highlights the advantages of adopting NlTH analyses to evidence critical features in the seismic response of existing buildings and to assess in advance the effectiveness of their retrofit strategy. To this purpose, the behaviour of the retrofitted building should be suitably modelled. This paper shows how this can be done when carbon fibre reinforced polymer is used to strengthen the critical sections. Two advanced finite element programmes are adopted in parallel to carry out the numerical analyses: SAP2000 and SeismoStruct. The differences involved in the numerical model are discussed and the main advantages of a three-step procedure based on the NlTH approach are evidenced.
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.
