Surface coating is generally achieved by an active operation: painting with a brush; withdrawing from a bath. Porous imbibition constitutes a more passive way: a porous material just put in contact with a reservoir containing a wetting fluid is spontaneously invaded. In this case, the material can eventually be filled by the fluid. If the aim is to

We describe nanoscale tools in the form of autonomous and remotely guided catalytically self-propelled InGaAs/GaAs/(Cr)Pt tubes. These rolled-up tubes with diameters in the range of 280-600 nm move in hydrogen peroxide solutions with speeds as high as 180 μm s(-1).

Abstract The authors anlayze the case of an Albanian refugee who was killed by the propellers of the outboard engine of a rubber dinghy while illegally attempting to reach Italy. The finding of multiple parallel, deep clear-cut injuries is uncommon, but highly characteristic of the object producing the lesions.

It is estimated that approximately 25% of the population of the United States participates in recreational boating activities in a given year. These activities result in 7,000 reported accidents, 60% of which result in injuries. Of these injuries, 19% are fatal (11.3% of accidents).

Propeller Induced Velocities in Ducted Propellers
SNAME Propellers '84 Symposium, 1984This paper presents the results of flow measurements in the nozzle opening of ducted propellers operating in both open and behind conditions. The open-water test measurements show the propeller induced velocities in nozzle opening differ from the results from conventional propeller measurements.

This report summarizes the available information on the toxicity of 15 propellants used in aerosols. After reviewing the results derived from various animal species, the following classifications are proposed: Low-pressure propellants of high toxicity: trichlorofluoromethane (FC 11), dichloromonofluoromethane (FC 21), trichlorotrifluoroethane (FC
