Variations of dry deposition velocity for S02 due to terrain-forced mesoscale circulations have been explored for northeast Colorado and south Florida. A mesoscale numerical model was used to obtain the wind and turbulence data needed to calculate the deposition velocities. Computations were performed both with and without consideration of observed land use characteristics. The results indicate...

The melting of an ultrathin lubricant film is studied at friction between atomically flat surfaces. We take into account fluctuations of lubricant temperature, which are defined by the Ornstein-Uhlenbeck process. Phase diagrams and portraits are calculated for secondand first-order transitions (the melting of an amorphous and that of a crystalline lubricants, respectively). It is shown that, in...

It has been suggested that, unless a major effort is made, the atmospheric concentration of carbon dioxide may rise above four times the pre-industrial level in a few centuries. Here we use a coupled atmosphere-ocean-land model to explore the response of the global water cycle to such a large increase in carbon dioxide, focusing on river discharge and soil moisture. Our results suggest that wat...

Introduction: Halvi is a traditional dairy product made from sheep milk in Mazandaran province, especially in the mountainous areas of Noor and Kojur. The fungus used in the preparation of Halvi is Auricularia auricula-judae. The present study aimed to investigate the chemical composition and microbiological properties of Halvi samples produced in various regions in No...

Eyelets, capstans and cylindrical surfaces are often used in thread, fiber and paper handling machinery to guide the axially moving element. In addition to providing positional control, these “guides” introduce dry friction forces that alter the vibration and stability characteristics of the system. This paper examines the lateral response of a string that slides through an elastically supporte...

Fourteen strains of Grifola frondosa (Dicks.) S. F. Gray, originating from different regions (Asia, Europe and North America) were tested for lignin degradation, ligninolytic enzyme activities, protein accumulation and exopolysaccharide production during 55 days of cultivation on oak sawdust. Lignin degradation varied from 2.6 to7.1 % of dry weight of the oak sawdust substrate among tested stra...
