abstract beet soilborne virus (bsbv) is a member species of the genus pomovirus with rigid rod particles and 3 positive single stranded rnas. the virus is transmitted by polymyxa betae and restricted to chenopodiaceae. a survey was conducted in 2005 for identification of bsbv in northern khorasan province. samples showing yellowing, elongated and upright petioles with narrow leaf lamina and hai...

We study a mass transport model, where spherical particles diffusing on a ring can stochastically exchange volume v, with the constraint of a fixed total volume V= sum(i=1) (N)v(i), N being the total number of particles. The particles, referred to as p-spheres, have a linear size that behaves as v(i) (1/p) and our model thus represents a gas of polydisperse hard rods with variable diameters v(i...

  Objective(s): This study was performed aiming to investigate the effect of particle engineering via spray drying of hydroalcoholic solution on solid states and physico-mechanical properties of acetaminophen.   Materials and Methods: Spray drying of hydroalcoholic solution (25% v/v ethanol/water) of acetaminophen (5% w/v) in the presence of small amounts of polyninylpyrrolidone K30 (PVP) (0, 1...

In hard disk drive manufacturing, the tolerance ring is commonly used for coupling a bearing cartridge to an arm actuator. Further, the tolerance ring can prevent slippage between the arm actuator and bearing assembly during operation of disk drive or during shock events. The metal scratch occurred in the tolerance ring installation process cause a number of particles. The main purpose of this ...

Rhombellanes are mathematical structures existing in various environments, in crystal or quasicrystal networks, or even in their homeomorphs, further possible becoming real molecules. Rhombellanes originate in the K2.3 complete bipartite graph, a tile found in the linear polymeric staffanes. In close analogy, a rod-like polymer derived from hexahydroxy-cyclohexane was imagined. Further, the ide...
