A cross-sectional seroprevalence study on leptospirosis, using microscopic agglutination test (MAT), was conducted in rural villages in Khammouane Province, Lao People's Democratic Republic, in December 2006. The overall prevalence of leptospiral infection among 406 subjects was 23.9% (95% confidence interval [CI] 19.7-28.0%). Independent risk factors for the infection, identified by multivaria...

The effectiveness and penetration of a novel, truck-mounted mist sprayer (3WC-30-4P provided by American LongRay) was evaluated with bifenthrin in a large, park-like setting with historic floodwater and woodland mosquito populations. Efficacy evaluations were determined through adult population collections and excised leaf bioassays. Trapping results showed a mean reduction of 77% in mosquito p...

Research has found that children possess a broad bias in favor of teleological--or purpose-based--explanations of natural phenomena. The current two experiments explored whether adults implicitly possess a similar bias. In Study 1, undergraduates judged a series of statements as "good" (i.e., correct) or "bad" (i.e., incorrect) explanations for why different phenomena occur. Judgments occurred ...

The durability of asphalt mixtures against floodwater immersion can serve as a reference to anticipate potential road damage. Moreover, Reclaimed Asphalt Pavement (RAP) materials have been discovered substitute for aggregate in pavement due their environmental friendliness and cost-effectiveness. Therefore, this research aimed assess the produced using RAP 1, 2, 4, 8 days. process involved Ston...

During operations, damage can occur with a resulting ingress or egress of fluid. The incoming water affects the reserve buoyancy and it also change stability hull girder loading. flooding event is vital that flow through damaged orifice movement floodwater around structure be predicted quickly to avoid further ensure environmental safety. empirical measure coefficient discharge used as simplifi...

Object detection and segmentation algorithms evolved significantly in the last decade. Simultaneous object paved way for real-time applications such as autonomous driving. Detection of (partially) flooded roadways are essential inputs vehicle routing traffic management systems. This paper proposes an automatic floodwater method utilizing Mask Region-Based Convolutional Neural Networks (Mask-R-C...
