Weanalyzed theprevalenceofhemagglutination inhibition(HI) antibodies toSt. Louis encephalitis (SLE)virus inwildbirdsduring the1990SLEepidemic in IndianRiverCounty.The initial presence of SLE HI antibody was associated signiÞcantly with modeled drought 15 wk prior, wetting conditions 1wkprior, and the emergenceof theFlorida SLEvirus vector,Culex nigripalpus, 5wkprior. Our Þndings indicated that ...

Saint Louis encephalitis virus caused an outbreak of febrile illness and encephalitis cases in Córdoba, Argentina, in 2005. During this outbreak, the strain CbaAr-4005 was isolated from Culex quinquefasciatus mosquitoes. We hypothesised that this epidemic variant would be more virulent in a mouse model than two other non-epidemic strains (78V-6507 and CorAn-9275) isolated under different epidem...

Background and Aim: Tooth discoloration induced by endodontic materials is a common finding which can impair the aesthetic outcome. The aim of this study was to compare the coronal discoloration induced by Well-Root ST and AH26 root canal sealers by using the Easyshade® colorimeter. Materials and Methods: Forty-five intact maxillary central incisors were involved in this experimental study. Th...

We explore the characteristics of 96,190 wet events (WEs) defined as consecutive 3-hourly rainfall ≥ 1 mm/3 hr from a network 34 stations across Bangladesh. Nearly 60% (5%) WEs last ≤ 3 (≥ 15) hr. The are dynamically clustered into four “canonical” storm types (STs), mostly discretized by their duration, but also mean and maximal intensity. While durations, total amounts contiguous areas positi...

in this paper, a new circuit is proposed for step-up z-source inverter based on qzsi (quasi-z-source inverter). the proposed topology inherits all advantages of the conventional topology. the proposed topology in comparison with conventional topology reduces the st (shoot-through) duty cycle by over 25% at the same voltage boost factor. theoretical analysis of the proposed qzsi in the st and no...
