Abstract It is difficult to explain rainfall from ice-free clouds, because the timescale for onset of rain showers shorter than mean time collisions between microscopic water droplets. has been suggested that raindrops are produced very rare ‘lucky’ droplets, which undergo a large number on short compared first collision. This work uses deviation theory develop estimates shower, as function col...

Abstract It was previously shown that the superdroplet algorithm for modeling collision–coalescence process can faithfully represent mean droplet growth in turbulent clouds. An open question is how accurately accounts fluctuations collisional aggregation process. Such are particularly important dilute suspensions. Even absence of turbulence, Poisson collision times suspensions may result substa...

Recurrent miscarriage is a less recognized feature of Wilson’s disease and adequate treatment can alter the outcome of pregnancies favourably. Wilson’s disease is a recessively inherited disorder of copper metabolism due to mutations in the ATP7B gene, which encodes for a coppertransporting P-type ATPase. Recurrent miscarriage is a complication of untreated Wilson’s disease. It has been reporte...

With huge quantities of multimedia information becoming available on the Internet everyday, our foremost mechanisms to find information still rely on text-based retrieval systems with their keywordbased query interfaces. However little to nothing is known about the retrieval performance and/or the quality of the user interface of these search engines. Often when a retrieval system is developed ...

In this issue of Blood, de Groot et al identify a hydrophobic pocket in the Cys-rich domain of ADAMTS13 that appears to interact with the hydrophobic pocket in the central A2 domain of von Willebrand factor (VWF) for its proteolysis.

is contribution is going to be a congratulation to Frederick Jelinek’s birthday jubilee. Before I reach the very congratulation I would like to remind a lucky moment that had a strong influence on the life of a certain Institute of Charles University in Prague aer 1989. And it is by no chance that the honored person witnessed the above mentioned moment and its consequences. From my personal p...
