The composition of the essential oil of wild bergamot bee balm introduced into the Krasnodarsk Krai has been analyzed by chromatomass spectrometry. The essential oil contains 34 components of which the main ones are -pinene (3.5%), -pinene (2.9%), -terpinene (1.7%), p-cymene (32.5), an aliphatic aldehyde (6.3%), sabinene hydrate (1.9%), -caryophyllene (1.1%), the methyl ether of carvacrol (5.5%), citronellyl acetate (1.6%), thymol (12.6%), and carvacrol (24.0%). The compounds were identified on the basis of their mass-spectrometric characteristics and arithmetical retention indices.A. N.

MNDO-PM3 and AM1 quantum chemical calculations of the molecular structure of N,N′-diphenyl-guanidine (DPG) prove that the
molecule preferably exists as an asymmetric tautomer with a basic center C = N−. IR and UV spectral data, dipole moments,
and average molecular weights of DPG solutions in nonpolar and low-polar solvents confirm the results of calculations, indicating
formation of hydrogen-bonded cyclic self-associates of DPG in solution.

The analysis and evaluation of the forces acting on the particle in a linear shear flow of power-law fluid (PLF) in the presence of the wall were performed. Using the results of a series of computations for a model problem with a spherical particle near a flat wall in the Reynolds number range of 0?200 and the distance to the wall from 0 to 20 particle diameters, the correlation formulas for calculating the coefficients of drag force and lift force were obtained. Special attention was paid to the behavior of the forces acting on the particle approaching the wall. 相似文献

Summary.
We consider the application of linear multistep methods (LMMs)
for the numerical solution of initial value problem for stiff delay
differential equations (DDEs) with several constant delays, which are
used in mathematical modelling of immune response. For the approximation
of delayed variables the Nordsieck's interpolation technique, providing
an interpolation procedure consistent with the underlying linear
multistep formula, is used. An analysis of the convergence for a
variable-stepsize and structure of the asymptotic expansion of global
error for a fixed-stepsize is presented. Some absolute stability
characteristics of the method are examined. Implementation details of
the code DIFSUB-DDE, being a modification of the Gear's DIFSUB, are
given. Finally, an efficiency of the code developed for solution of
stiff DDEs over a wide range of tolerances is illustrated on biomedical
application model.
