CFD Study of an Innovative Catamaran with Asymmetrical Hulls
2013
The purpose of this paper is the study of the shape of catamaran with asymmetrical hulls by both experimental and numerical viewpoint. The experimental study is based on the towing tank tests on a catamaran hulls shape obtained from previous works, showing that the wave resistance is very low produces a lower energy loss and a greater effectiveness. The hulls shape is optimized by the CFD application by force of commercial software, which shows that the reduction of wasted energy is very sensitive to make some changes; in particular three different width of the catamaran are tested and their performances are compared.
ANALISI CFD DELLE PRESTAZIONI DI UN CATAMARANO CON SCAFI ASIMMETRICI DOTATO DI SOSTENTAMENTO IDRODINAMICO
2010
Nel presente lavoro è proposto uno studio di ottimizzazione su di un catamarano a scafi asimmetrici con murate piane esterne, grazie al progetto di due alettoni posizionati trasversalmente alla direzione del moto al di sotto del piano di galleggiamento ai quali è affidato il sostentamento idrodinamico dell’intero catamarano. L’obiettivo finale dello studio è quello di ridurre la resistenza totale all’avanzamento del catamarano dopo aver progettato in maniera opportuna le due appendici alari. Le analisi CFD, sia del catamarano senza alettoni che del catamarano con agli alettoni, hanno dato la possibilità di operare un confronto tra i due catamarani evidenziando un beneficio del 38% in termin…
Predictor variables for half marathon race time in recreational female runners
2011
Import JabRef | WosArea General and Internal Medicine; International audience; INTRODUCTION: The relationship between skin-fold thickness and running performance has been investigated from 100 m to the marathon distance, except the half marathon distance. OBJECTIVE: To investigate whether anthropometry characteristics or training practices were related to race time in 42 recreational female half marathoners to determine the predictor variables of half-marathon race time and to inform future novice female half marathoners. METHODS: Observational field study at the 'Half Marathon Basel' in Switzerland. RESULTS: In the bivariate analysis, body mass (r = 0.60), body mass index (r = 0.48), body …
Participation and performance trends in multistage ultramarathons--the 'Marathon des Sables' 2003-2012
2012
International audience; BackgroundThe purpose of this study was to investigate participation and performance changes in the multistage ultramarathon 'Marathon des Sables' from 2003 to 2012.MethodsParticipation and performance trends in the four- or six-stage running event covering approximately 250 km were analyzed with special emphasis on the nationality and age of the athletes. The relations between gender, age, and nationality of finishers and performance were investigated using regression analyses and analysis of variance.ResultsBetween 2003 and 2012, a number of 7,275 athletes with 938 women (12.9%) and 6,337 men (87.1%) finished the Marathon des Sables. The finisher rate in both women…

Phytotoxic effects of Lantana camara, Eucalyptus camaldulensis and Eriocephalus africanus essential oils in weeds of Mediterranean summer crops
2009
Abstract The essential oil composition of Lantana camara , Eucalyptus camaldulensis and Eriocephalus africanus was analyzed by means of GC and GC–MS and bioassayed in order to determine their activity against Amaranthus hybridus and Portulaca oleracea . E. camaldulensis essential oil, with spathulenol as the main compound, was the most effective, completely inhibiting germination and seedling growth on both weeds. The essential oil of E. africanus , rich in artemisia ketone, showed activity similar to that of E. camaldulensis on A. hybridus , but it was not so effective against P. oleracea , and L. camara essential oil, with high percentages in sesquiterpene hydrocarbons, also showed higher…
Chemical Composition of the Leaf Oil ofLantana camara
2005
The essential oil of the fresh leaves of Lantana camera growing in Dehra Dun was analyzed by GC and GC/MS. The major constituents identified in the oil included β-caryophyllene (23.3%), α-humulene (11.5%), germacrene D (10.9%), davanone (7.3%) and γ-curcumene (6.3%).

Vihreän fasismin vastustaja : Fadela Amaran tekstit hallinnan analytiikan näkökulmasta
2012
Tutkimuksessa tarkastellaan Fadela Amaran, ranskalaisen feministin ja järjestöjohtajan, näkemyksiä ongelmallisista lähiöistä hallinnan analytiikan näkökulmasta. Ministerinäkin lyhyen aikaa toiminut Amara tunnettaneen edelleen parhaiten perustamastaan lähiöiden naisten oikeuksia puolustavasta järjestöstä, Ni Putes Ni Soumises. Lähtökohtana tutkimukselle on kiinnostus tutkia lähiössä kasvaneen siirtolaistaustaisen musliminaisen ajatuksia lähiöistä ja niiden asukkaista, joista merkittävä osa on myöskin siirtolaistaustaisia ja ainakin kulttuuriselta taustaltaan muslimeja. Tutkimus on luonteeltaan tekstitutkimusta ja sen aineisto muodostuu kolmesta Amaran kirjasta: Ni P…
