Numerical modelling on the performance of submerged breakwater using the SPH-based DualSPHysics model

Implementation of coastal structures are known to mitigate issues of coastal erosion and impacts of sea waves during storm events on coastal areas. Among the various coastal structures implemented in Malaysia, the submerged breakwater called as WABCORE is being studied. This structure was originally designed by the National Hydraulic Research Institute of Malaysia and has been implemented at the shores of Pulau Tinggi, Johor, Malaysia. The objective of this study is to identify the wave transmission coefficient of the improved WABCORE structure under a variety of wave conditions. The effect of wave steepness (Hi/L) parameter on the wave transmission coefficient would also be highlighted. The study also considers the arrangement of the WABCORE structures, whereby the structures are stacked in a 4:3:2 (broad) and 3:2:1 (narrow) manner. This study implements the use of an open-source code known as DualSPHysics to simulate the various conditions. The results signify that the WABCORE structure is capable of dissipating waves despite its various condition

Choriocarcinome ovarien: Difficultés de la prise en charge médicale d\'un cas dans un centre sous-équipé à Abidjan, Côte d\'Ivoire.

Ovarian choriocarcinomas are rare malignant germinal tumours representing 1 % of all ovarian tumours. There are two main types: the gestational (which are more frequent), and the non-gestational ovarian types. The authors report one case in a 43 years old patient (G5 Para 3) with a history of two abortions, and highlight the therapeutic difficulties encountered. She was referred to the Gynaecology Service of the University Teaching Hospital Treichville, Abidjan, for the management of a left ovarian choriocarcinoma, confirmed on histological examination after total hysterectomy. The management of the patient in our health facility did not permit us to determine whether it was of gestational origin or not. Moreover, it was very difficult choosing an effective therapeutic regimen, and finally a combination of cyclophosphamide, adriblastine, cisplatin gave complete biological and clinical remission.Les choriocarcinomes ovariens font partie intégrante des tumeurs germinales malignes. Très rares, elles ne représentent que 1% de l\'ensemble des tumeurs ovariennes. On distingue 2 types principaux : ceux d\'origine gestationnelle qui sont les plus fréquents et ceux d\'origine non gestationnelle. Les auteurs rapportent un cas de choriocarcinome ovarien, en insistant sur les difficultés thérapeutiques rencontrées. Il s\'agissait d\'une patiente de 43 ans, 5ème geste, 2ème pare avec 2 interruptions de grossesse. Elle a été adressée au service de gynécologie du Centre Hospitalier et Universitaire de Treichville à Abidjan (Côte d\'Ivoire), pour prise en charge d\'un choriocarcinome ovarien. Ce diagnostic avait été confirmé après un examen histologique de la tumeur ovarienne gauche après hystérectomie totale. La prise en charge de la patiente dans notre contexte de travail a montré non seulement l\'impossibilité de déterminer l\'origine gestationnelle ou non gestationnelle de la tumeur, mais surtout les difficultés dans le choix des protocoles thérapeutiques. Dans notre cas l\'association cyclophosphamide, adriblastine, cysplatine a permis la rémission complète biologique et donc la guérison. Keywords: Choriocarcinoma - Ovary - Surgery - Chemotherapy.
