Title s the Mechanism of Compression of Current in a Fast and
Powerful Gas Discharge.
Orig !,ub % Atori, onorgiya, 1956, No 3, 81-83
Abstract % A study is rtrdo of the comprossion of a colutm of gee, crr-
rying a current that incroasoo rapidly with tine, It is in-
dicated that the fundamental role in plryod in this crao by
the magnetic forces that compress the Fes (rutunl Pttraction
of pnrrllol currents), ehprgo distribution, end the inertia of
the Fes. The tire vrriction of the radius of the gas column
a is determined fron the equation
R 6609 + A
whore :i is the mass of the gee per unit lcngth of column, p
the Pverage gas pressure, and I the current. The coefficient
1/3 must be introduced, boccuse the mass of the Lzas is not
concentrated in c circle of radius a, but is distributed over

ABSTRACT: As introduction a short curriculum vitae of the scientist,
who was born on July 31, 1908 in Liepaja (Latvia), is given.
Subsequently his work is discussed in ietail.
&).Publications on the classical theory of oscillation:"Some
Problems in the Perturbation Theory of Linear Oscillation
Systems" was the title of his first publication (Ref 1); a
theoretical investigation of the oscillations of thin dia-
phragms fastened at a finite number of points followed one
year later. b) Publications on the theory of solids: "On the
Theory of the Photoeffect in Metals", "On the Trarsmission
Band in Silver", "Concerning the Theory of Liquid Metals",

Semen Petrovich Shubin (On the Occasion of the Fiftieth SOV/53-65-4-12/17
Anniversary of His Birth and of the Twentieth Anniversary of His Death)
"On the Theory of Exchange Interaction", "Problens of the
Quasiclassical Treatment of Ferromagnetism" and others.
c) Publications on physical statistics: A summary of statistical
formulae is mentioned. d)Publications on quantum electro-
dynamics and theory of the quantized fields: "Classical Analog
to the Dirac Theory of Emission", "On the New Dirac Theory
of the Electromagnetic Field" and others. Finally a liat
of scientific papers published by Shubin is given (18 papers,
written partly in German, English, and French). There are I
figure and 26 references, 21 of which are Soviet.

APSTRACT: The author investigates the instabi3lty connecied with the PIAOMM
inhomageneity at the rim of a beam of finite vidth, in a Tnagn tic field, The
starting point is a system of linearized kinetic equations with self-sufficient
field for electrons and ions, and the maxwell, field equations., collisions are dis-

considered separately* It turns out that the rims of the beam are unstable vith
respect to short vavelangth perturbations vhich do not appear in a homogeneous
pla-a., even if the beam velocity is smaller than the the=&l. velocit-i of t4w

author considers a problem of this kind vhich permits a xigorous solution, A
uniformly charged filament Is assumed to move vith a constant speed parallel to a
system of perfectly conducting semiplanes. The electromagnetic field is described
by a Hertz' vactors consisting of the field of the charged filament moving In empty

'ABSTRACT: An expression for the diffusion coefficient of dilute so-

iof the general macroscopic diffusion equations and the thermodynamic

Periodical : Byul. eksp. biol. i med. 39, 74-77, Jan 1955
Abstract : The article describes an electrolytic method for the destruction
of deep sections of the brain without damage to more superficial
tissues. Author reports that the method was developed during the
last century by the Russian scientist F. F. Golltsinger but was
adopted by foreign scientists. The instrument uses a BAS-80 ator-
age battery, a milliameter and potentiometer to control the cur-
rent. The inert lead cathod is attached to the animal's pew; the
anode consists of a silver or platinum wire covered with bakelite
lacquer or a glass tube. The end (0.5-2 mm) remains uncovered de-
pending on the extent of the injury contemplated. It is best to
use platinum wire which does not corrode as easily as silver. Ref-

a limit cycle of the same clans arises. Case 1. The linit
cycle arises from a eeparatrix loop. The authors give con-
ditiona which are sufficient for the stability (or instability)
of the loop and simultaneously necessary for the formation of
a unique stable (or instable) boundary cycle. Case II. The limit
cycle arises from the separatrix of a state of equilibrium
"saddle - knot" which tends to a saddle - knot for t-++ oo as
well as for t- - oo which, however, is a separatrix only for
t--.b.+ cu or only for t-- co . It is ntated that in this case
always only one limit cycle is possible. Altogetber there are

TITLEt Rynnic, systems of the first order of refinement in the plane
SOURM Matematioheskiy sbornik# v, 689 no- 39 19659 328-372
TOPIC TAGSs dynamic system, system analysiop dynamic behaviort trajectory analysis
ABSTRAM The class of simple refined systems called "systems of the first order of
-refinement" is considered. Systems of this type are found among the systems in the
plane# that is, systems of the form
!L = Q (x..
'_dT P (Jr' Y)' -7,
where x and y are the Cartesian 'coordinates in the planei. The concept of the
"coarseness" of dynamic systems is defined in terms of the variables and vector spac
involved. Conditions necessary for a system of the first order of refinement are
,established. Three conditions are stated; the violation of any one of these three
conditions is necessary for the given system to be of the first order of refinement.
The discussions are based on the theorem of "minor variation of the solution and
derivatives from the solution according to initial values from the variation of the
righthand side" (see A. A. Andronov and Ye. A. Leontovich (Rozhdenive predelfrVkh

40 (82) (1956L 179 - 224))- Fifteen theorems and several lemmas are stated and
proved, The conditions established in these theorems are the first order of refine-
ment conditions and are termed the r conditions. The proof that the r conditions
are also sufficient conditions for a system of the first order of refinement is left
for subsequent publication, Orig. art, haet 17 equations.
