Many phenomena in nature and technology are associated w.th the filtration of suspensions and colloids in porous media. Tw. main types of particle deposition,namely, cake filtration at the inlet and deep bed filtration throughout the entire porous medium, are studied by different models. A unified approach for the transport and deposition of particles based on the deep bed filtration model is proposed. A v.riable suspension flow.rate, proportional to the number of free pores at the inlet of the porous medium, is considered. To model cake filtration, this flow.rate is introduced into the mass balance equation of deep bed filtration. For the cake filtration w.thout deposit erosion,the suspension flow.rate decreases to zero, and the suspension does not penetrate deep into the porous medium. In the case of the cake filtration w.th erosion, the suspension flow.rate is nonzero, and the deposit is distributed throughout the entire porous medium. An exact solution is obtained for a constant filtration function. The method of characteristics is used to construct the asymptotics of the concentration front of suspended and retained particles for a filtration function in a general form. Explicit formulae are obtained for a linear filtration function. The properties of these solutions are studied in detail.

Using the landau and symmetric gauges for the v.ctor potential of a constant magnetic field and the quantum problem of a charged particle mov.ng on a flat surface, w. show.the classical electromagnetic gauge transformation does not correspond to a one-dimensional unitary group transformation U(1) of the w.v. function for the quantum case. In addition, w.th the re-examination of the relation betw.en the magnetic field B and its v.ctor potential A, w. found that, in order to hav. a consistent formulation of the dynamics of the charged particle w.th both expressions, w. must hav. that B=∇×A if and only if B≠0.

Based on the collected multiw.v.length data, namely in the radio(Nv.S, FIRST, RATAN-600), IR(w.SE),optical(Pan-STARRS), Uv.GAlEX), and X-ray(ROSAT, Sw.ft-XRT) ranges, w. hav. performed a cluster analysis for the blazars of the Roma-BZCAT catalog. Using tw. machine learning methods, namely a combination of PCA w.th k-means clustering and Kohonen's self-organizing maps(SOMs), w. hav. constructed an independent classification of the blazars(fiv. classes) and compared the classes w.th the know. Roma-BZCAT classification(FSRQs, Bl lacs, galaxy-dominated Bl lacs, and blazars of an uncertain type) as w.ll as w.th the high synchrotron peaked(HSP) blazars from the 3HSP catalog and blazars from the Tev.at catalog. The obtained groups demonstrate concordance w.th the Bl lac/FSRQ classification along w.th a continuous character of the change in the properties. The group of HSP blazars stands out against the ov.rall distribution. w. examine the characteristics of the fiv. groups and demonstrate distinctions in their spectral energy distribution shapes. The effectiv.ness of the clustering technique for objectiv. analysis of multiparametric arrays of experimental data is demonstrated.
