Proteus mirabilis colonies exhibit striking geometric regularity. Basic microbiological methods and imaging techniques were used to measure periodic macroscopic events in swarm colony morphogenesis. We distinguished three initial phases (lag phase, first swarming phase, and first consolidation phase) followed by repeating cycles of subsequent swarming plus… (More)

The kinetic energy distribution function satisfying the Boltzmann equation is studied analytically and numerically for a system of inelastic hard spheres in the case of binary collisions. Analytically, this function is shown to have a similarity form in the simple cases of uniform or steady-state flows. This determines the region of validity of hydrodynamic… (More)

This paper compares theory and experiment for the kinetics of time-dependent sedimentation. We discuss non-interacting suspensions and colloids which may exhibit behavior similar to the one-dimensional motion of compressible gas. The velocity of sedimentation (or creaming) depends upon the volume fraction of the constituting particles and leads to… (More)

We analyse derivative securities whose value is not a deterministic function of an underlying which means presence of a basis risk at any time. The key object of our analysis is conditional probability distribution at a given underlying value and moment of time. We consider time evolution of this probability distribution for an arbitrary hedging strategy… (More)

Fifteen fluorescent pseudomonads, isolated from the rhizosphere of agricultural plants, were similar in both their phenotypic properties and the chemical nature of produced pigments, to the previously described Pseudomonas fluorescens var. pseudoiodinum. DNA-DNA hybridisation data showed their genetic similarity (but not identity) to different biovars of P.… (More)

Earlier, we described a new family of mesophilic, strictly autotrophic Fe2+-oxidizing archaebacteria, Ferroplasmaceae, which belongs to the order Thermoplasmales and includes the genus Ferroplasma and the species F. acidiphilum (strain YT) [1]. The present work is concerned with a comparative study of phenotypic characteristics of the type strain YТ and a… (More)

Colloidal suspensions aging under gravity have long been known to spontaneously separate into layers. We demonstrate through flow visualization experiments that a lateral temperature gradient as small as 10 mKycm can be responsible for such stratification and that strata correspond to a stack of convection rolls. A linear stability analysis suggests that… (More)

MALDI mass spectrometry (MS) of 14- to 42-mer homogeneous oligonucleotides and their mixtures was carried out using a Vision 2000 instrument (Thermo BioAnalysis, Finnigan, United States). Conditions for the determination of oligonucleotide molecular masses were optimized by applying various matrices and operation modes. The most reproducible results with… (More)

By MALDI MS, we searched cobra venoms for new low-content polypeptides. A number of new proteins with molecular masses 7-25 kDa, characteristic of the known snake protein toxins, were identified, with the content of one of them less than 0.02%.
