A 34-year-old laboratory worker developed murine typhus after an accidental splashing of Rickettsia typhi over her right eye and lips. Indirect immunoperoxidase test showed a four-fold increase in titre to Rickettsia typhi. She responded well to doxycycline.

In nature, high-speed raindrops often impact and spread on particulate surfaces (e.g., soil, plant leaves with spores or pollen). We study the dynamics of droplet a loosely packed monolayer particles by combining experimental mathematical approaches. find that presence mobile lowers critical velocity at which exhibits corona splashing, as particle area fraction is systematically increased. rati...

The significant effect of an external dc magnetic field on the splashing behavior ethanol drops impacting unstructured (flat) surface soft magnetoactive elastomers (MAEs) is reported. Weber number corresponding to transition between deposition and regime reduced by ?20% in a moderate ?300 mT. Alongside this effect, two-fold increase initial deceleration ejection sheet observed for softest sampl...

We report high-speed optical and X-ray observations of jets formed during the impact of a drop with a deep pool of the same liquid. We show that a scaling which relies entirely on liquid properties, as is conventionally employed, is insufficient to determine the threshold for splashing. In order to determine if the gas properties could account for this deficit, we conducted experiments with dif...

When a droplet hits surface fast enough, splashing can occur: smaller secondary droplets detach from the main during impact. While on smooth surfaces is by now well understood, roughness also affects at which impact velocity splashes. In this study, influence of investigated. By changing root mean square impacted surface, we show that only affected when large enough to disrupt spreading lamella...

A numerical model is used to simulate the fingering and splashing of a droplet impacting a solid surface. A methodology is presented for perturbing the velocity of fluid near the solid surface at a time shortly after impact. Simulation results are presented of the impact of molten tin, water, and heptane droplets, and compared with photographs of corresponding impacts. Agreement between simulat...

The purpose of this paper is to obtain the tracking interval for difference of expected Kullback-Leibler risks of two models under Type II hybrid censoring scheme. This interval helps us to evaluate proposed models in comparison with each other. We drive a statistic which tracks the difference of expected Kullback–Leibler risks between maximum likelihood estimators of the distribution in two diff...

The splashing of a water drop is a fascinating phenomenon that results from a variety of complex interactions between the drop and the material it impacts. In general, the distribution of droplets of a splash depends on the drop size and velocity; the surface roughness, rigidity, and wetness; and the angle of impact. Given the number of factors involved, it is difficult to develop an analytical...
