ABSTRACT: The dynamic principle in the presentation ("reflection") of the regulari-
ties in tile transformations of the vegetation cover on geobotanical maps is being de-
veloped by the French and German schools of geobotanical cartography. In the SSSR,
the realization of this approach dates from 1928. Major efforts are,12'6wever, of more
recent origin (1959). The dynamic transformations of the south tayga forest vegeta-
tion are most,frequently related to antropogenic cauSeS, - forest fires, forest ex-
ploitation, convefsionto-farmland and farming abandonment. In arid and mountainous
regions, major veget 'ation changes are known to be fastj In the plains of tile southern
tayga, except in the marches, these clianges are quite slow and thus cannot be reflec-
ted in maps. However, certain phytogenic changes, e.g. in the composition of vegeta-

ABSTRACT: A Q factor,modulato that increases the output pulse power of a ruby laser
by 103 is described. The modulator is made up of an optical head and an electronic
unit. The optical head consists of a rotating prism with total internal reflection
that acts as one of the mirrors of the laser optical resonator; it is,driven at
angular speeds up to 26 x 103 rpm by a dc motor'. The electronic unit consists of a
square wave generator, a comparator circuit, two time delay networks, a trigger cir-
cuit, a dc motor, and a power supply. The modulator operates in the following mannert
at a given angular position of the prism with respect to the laser beam, light from a
lamp is focused through a lens and illuminates a photosensitive diode. The output
pulse of the photodiode is amplified and fed to the comparator. When the rotational
speeds of the motor and the prism are equal, the comparator initiates a pulse that
lightsthe laser pumping lamp and thus triggers the laser. At the same time, the

motor is stopped and the laser is not triggered again until the motor build$ up its
speed until it is equal to that of the prism. The motor has an automatic disconnect
relay which stops it in 5 to 7 seconds if a faulty condition occurs in the circuit.
As a result of work with the modulator, optimum parameters for the optical resonator,
rotation speed of the itflector, and pumping power have been determined in order to

ABSTRACT A donor of the angle 9,which is of comparative structural simplicity, is
described. It facilitates immediate recording on the oacillograph,has no
inertia, and can be used for the recording of procausas with practically un-
limited variability of this angle, The donor may have vary high accuracy
and depends on the parameters of the elements used, The system consists of
three elements- the Impulso.giver, the transformer- consisting of a thyra-
tron, an electron tube$ an RC member - and an amplifier; In order to avoid
the disadvantage accompanying the use of filters (inortia), an RG member,
which is switched on to the rectangular voltage wave, is used. Systems with
one thyratron and one diode and a system with two thyratrons and one dis-
charge disk are described. In the former case e is fixvd ontia oscillogram

ABSTRACT: If one or several control windings of the el-ectrodynamic ampli-
fier (EDA) are fed by an electronic amplifier (F&), it is
convenient to design an EA with such a characteristic that
the common amplification coefficient of the EDA und of t-he
EA remains unchanged. To this end, the product of.the tangents
of the angles of inclination.in the amplification character-
istics must remain constant over the whole.mange-of signal

the no-load characteristic of.the.EDA is-not unambiguous.but
is expressed by a hysteresis.loop.depeading.on thaLiiiitial,

is determined in dependence on the necessary amplification

TITLE: Compensation of the Resistances in Slow-speed Processes
PERIODICAL: Elek-tricheotvo, 1959, Nr 10, pp 68-72 (USSR)
ABSTRACT; It is shown here that slov-speed processes allow for
compensation of the ohmic resistance and reactance with tho help
of circuit diagrams similar to those of automatic control. The
time constants of the circuit-diagram elements greatly influence
the compensating resistance. The author demonstrates that the
compensating resistance greatly depends on the frequency at large
values of the time constants. The value of the compensating
resistance is easily obtained from the amplitude-versus-.phase
characteristics of the open system. It is recommended to choose
the compensating resistance according to the stability conditions
of the system; In rapid-speed "recesses, the corre3poliding
point on the amplitude-versus-phase characteristics is found 11car
the origin of coordinates. This is why the equivalent circuit
resistance is here almost equal to the natural one (without
Card 1/2 compensation). This is exemplified in an appendix by the

this project is to detetminethe optimum magnet shape and dimensions, to
ovaluate the need for coft-iron pole shoes and to determine the effect of
otabilization on the mAgnituda of useful flux@ Thv 4eoign.aalculationq

cross-section were varied# the leakage flux was assumed to be concentrated
at the ends. On the basis of plotted curves of useful flux vs. magnet
length it was found that the pole shoe becomes ineffective for a pole
eh; maximm useful flux was obtained
width greater than 50% of the pole pit
at 80% pole pitch withbut shoes., More accurate results and better agree-
ment with test data is obtained without assuming a concentrated leakage
flux and by considering the efrect of the airgap dimensions on the leakage
flux. For this purpoqp the magnet is divided Into n sections and each . , - - -!

those obtained with n-1 sections ( n= 4 was found to be sufficient for a

integration were both used to calculate certain special magnet shapes
i(pyramidal) and both gave practically the same results. In designing the
-motor it is possible to use either a single magnet on one side or tmo mag--
*nets which should be located symmetrically. The latter case gave 30% more

TITLE: on the Role of Indirect Interaction in the Theory of the

PERIODICAL: Fizika metallov i metallovedeniye, 1959, vol 8, Nr 3,
PP 330-336 (USSR)
ABSTRACT: Usually the ferro and antiferromagnetism of transition
metals is explained by the exchange interaction between
the electrons of inner d-shells. If the exchange
interaction integral between nearest neighbours is
positive, then the metal is a ferromagnetic, while if
it is negative the metal is antiferromagnetic. Such a
treatment of magnetic properties meets with a number of
difficulties. A large group of experimental data cannot
be explained ifith the aid of the Bethe-Slater curve for
tho exchange integral of transition metals (Ref 1).
Moreover, the majority of theoretl*cal estimates of the
exchange integral gives it a negative sign (Ref 2).
Secondly, it has recently been found (Ref 3) that
diluted alloys of manganese with noble metals are either
Card 1/5 ferro or antiferromagnetics. In these alloys the atoms

of the transition metal are at such large distances from
each other that direct exchange coupling between them is
entirely excluded. Similarly, ferro and antiferro-
magnetism of rare earth metals cannot be explained by
unusually weak direct coupling between magnetically active
electrons. These considerations have led to a search for
other possible mechanism of exchange coupling. One of
such mechanisms is the indirect exchange interaction
suggested by Zener (Ref 1). The present work is
concerned with the effect of indirect interaction in the
ferromagnetic problem. The theory is based on the
s-d-exchange model of transition metals put forward by
Vonsovskiy, his coworkers., and Berdyshev (Refs 4, 5). The
Hamiltonian which describes the interaction between
conduction electrons and spin waves in a fez-romagnetic
is given by Eqs (1) and (2) (Ref 4). In these equations

first order corrections of the perturbation theory. The
contribution due to the "triple" terms in the energy
spectrum was not considered and it is the aim of the
present work to elucidate the effect of these terms on
the energy of the system and its magnetization. It is
shown that the second approximation of the perturbation
theory on the s-d-exchange model of transition metals
leads to the appearance of an indirect interaction between
d-electrons. When this interaction is taken into account
the existence of ferromagnetism becomes possible in the /

negative d-d-exchange integral. An expression is derived
for the d-d-exchange integral and this is given by Eq (11).
Froin this expression it can be seen that in the present
theory the energy of the spin wave is considerably
altered in comparison with the exchange model. Firstly,
the second order correction of the energy has led to the

depends on the Fermi energy and the transport integral

integral is not very dependent on temperature. Finally,
the second order correction of the energy completely
cancels the effect of the first order correction so that
the "zero" energy 1k, which was considered earlier in
Refs 4 and 5, is completely absent in the spin wave energy,

ABSTRACT: The ferro- and antiferroma~netism of transition metals can be
explained by the exchange interaction between the electrons of
the internal d-shells of the atoms. The theoretical troatment
or this problem by m6ahs of the exchange interaction integral
meets with a number of-difficulties (Ref 1). Thus, firstly, the
large group of experimental data cannot be explained by t-he
Bethe-Slater (Bete, Sleyter) curve for the exchange interaction
integral of transition metalso Secondly, the majority of
theoretical estimates of this integral leads to a'negative
sign (antiferromagnetic)(Ref 2)~ and, thirdly, diluted alloys
of manganese with noble metal's show ferro- or antiferromagnetism
(Ref 3)- In view of the fact that by means of this theory it
is apparently not possible' to describe these phenomena

ABSTRACT: In the previous paper (Ref 1) a study was made of the
indirect interaction between d-electrons in the
ferromagnetic problem. It was shown that the indirect
interaction between electrons in inner and incompletely
filled shells, in the atoms of transition metals and
rare earths, favours the formation of a ferromagnetic
state. In the present paper an estimate is made of the
role of indirect interaction in setting up antiferro-
magnetic order. The Hamiltonian for an antiferromagnetic,
according to the s-d exchange model put forward by
Vonsovskiy (Ref 2),i5 of the form shown on p 481
where a k and ak(-) are the Fermi second quantization

operator for the n-th lattice site, J is the d-b
exchange integral for two nearest neighbors, I is tbe
s-d exchange integral (assumed independent of the
momentum of conduction electrons)g V is the volume of
the system, Ek = Ak2 is the energy of a conduction
electron, A is the transport integral (Ref 3) and
S = 1/2. The spin operators can be related to the Bose
operators by the two equations at the bottom of p 481
and top of p 482. The Hamiltonian obtained in this way
is shown at the top of p 482 where z is the number of
nearest neighbors for a given atom,
Yx
and 0 is the radius vector from the atom to its
nearest neighbor atom. After diagonalization, the
Hamiltonian can be thrown into the form shown at the
Card 2/4 bottom of p 482 where e% and g(%) are defined by the

relations at the bottom of p 482. The energy of the
system in an external magnetic field, the free energy
and the magnetization are then calculated in a way
similar to that employed in the previous paper (Ref 1).
It is shown that if the interaction of spin waves with
conduction electrons is taken into account, then the
interaction between d-electrons is characterized not by
the d-d exchange integral but by a certain effective
exchange integral Jeff which is given by Eq (6), in
which 15 is the chemical potential of the conduction
electrons. It follows from this equation that in the
absence of direct d-d exchange interaction, the
integral Jeff is negative, which means that the energy
of the spin wave also becomes negative and an
antiferromagnetic state cannot be reached. It is
concluded that indirect exchange interaction in general
favours ferromagnetism and tnis agrees with Zener's
hypothesis. The electronic specific heat of transition
metals is also affected by indirect interaction. The

ABSTRACT: So far, no superconducting antiferromagnetic metals have
been detected and therefore it is of interest to investigate
the criterion of superconductivity in these. In the
antiferromagnet:Lc metal Interactlomof conductivity
electrons with spin waves occur which are specific for such
metals. In this brief note, the author investigated
mathematically the problem of the influence of this inter-
action on the occurrence of a superconducting state. It is
shown that electron-magnon interaction leads to effective
interaction of electrons with pulses of opposite polarity
and spins and this interaction is repulsive ir. character
in contrast to the electron-phonon interaction. The bond
energy of the Cooper electron pair, forming as a result
of electron-uhonon interaction, can only decrease and the
Cardl/2 pair can generally be annihilated as a result of scattering

of electrons on the spin waves. The repulsive character
of the electron-electron interaction, due to exchange with
spin waves, is explained by the fact that the scattering
of electrons is accompanibd by spin Clip. If one of the
electrons of a Cooper pair is scattered on a Spin wave,
it changes the direction of its spin; electrons with
parallel spins cannot form a conjugate pair.

TEXT. The superconductivity criterion for antiferromagnetic
materials was discussed by the present author in Refs.1 and 2.
In Ref,2 use was made of a reduced electron-electron Hamiltonian
des---ribing the interaction between electrons with opposite momenta
and spins due to spin-wave exchange effects in antiferromagnetics.
The positive sign of the effective interaction potential showed
that electrons forming a Cooper pair repel each other as a result
of scattering on magnons, In the present note the author discusses
the effect of inelastic scattering of electrons by magnons on the
appearance of superconductivity, using the method proposed by
Bogolyubov in Ref,,3, The flamiltonivn for the electron-phonon-
spin-wave system consists of three parts (P~301) and includes the
s - d exchange integral I , the electron-phonon coupling
constant 9 the chemical potential of conduction electrons
and the number of nearest neighbours z . The Dogolyubov

TEXT. Following the discovery of superconducting ferromagnetics
by Matthias et al (Ref,l), the problem of the connection between
superconductivity and ferromagnetism has acquired a considerable
interest, Vonsovskiy and Svirski- (Ref.2) have shown that the
magnetization of the conduction electrons by the exchange "field"
prevents the formation of a superconducting state. However, no
one has so far investigated the effect of inelastic scattering of
conduction electrons by spin waves of the superconductivity of a
ferromagnetic, The present author investigates this problem using
the Hamiltonian of the s -d exchange model put forward by
Vonsovskiy and Turov in Ref.3. The Hamiltonian is simplified by
neglecting terms responsible for the magnetization and retaining
terms responsible for inelastic scattering. This simplification is

said to be justified by the fact that the role of the neglected

(Ref.2) and the analysis would only be complicated by them without
altering-the overall qualitative pi--ture, The results obtained
from this analysis are in complete agreement with the results of
Kasuya (Ref.8) who showed that spin wave exchange leads to an
effective repulsion in the case of electrons with opposite momenta
and spins in the neighbourhood of the Fermi surfa--e. It is shown
that electron-magnon interaction prevents the transition to

TEXTt In the electron spectrum of metallic crystals which are composed
of elements of the transition group and of the rare-earth group, special
properties are observed compared to the crystals of other metals. This is
brought into connection with the d- and f-shells of the electron sheath.
The electron density of the transition metals is divided into three
regions. The first is near the nucleus, the second consists of the valence
electrons, and the third intermediate region consists of the electrons of
the non-closed shells. For this system the Hamiltonian (i) is written down.
The present paper describes the influence exerted by the non-diagonal

Title Deztructive hydrogenation of tetraethylsilane
Periodical Zhur. ob. khim. 24/2, 2,69-272, Feb 1954
Abstract The reaction of hydrogenation of tetraethylsilane,in the vaporous phase Was.
investigated at normal pressures. It was established that the absence of cat-
alysts~does-in no way cbanpe the tetraethylsilane hydro.-en even at a tempera-
ture of 5000. A temperature much higher than 5000 results in the pyrolysis of
the tetraethylsilane and the formation of elementary Si and sortie gaseous pro-
ducts. At a temperature of about 5500 the tetraethylsilane is split, by thu
hydrogen over an A12(SiO3) catalyst forming triethylsillane and ethane.. The
mechanism of destructive hydrogenation of tetraethylsilane is explained. Sev-

by the Re-esterification of Ethyl Silicic Ether with Phenols (Iseledovaniya

PERIODICALt Zhurnal Obahchey Khimiij 1957) vol 27, No 2, pp. 325-327 (U.S.S.R.)
ABSTRACT: Experiments shoved that ethyl silicic other in the presence of a homologous
sodium phenolate reacts easily with phenols of different structures. This
reaction was considered to be very simple and also suitable for the
synthesis of tetrasroxysilanes with yields of about 70 - 85%. By employ-
ing this reaction method, the authors synthesized eleven tetraaroxysilanes
as well as orthosilicic ethers of cyclohexanol, cy-clopentanol and benzyl
alcohol.
The physico-chemical properties of the tetraaroxysilanes obtained are
dezeribed in a table. When exposed to ultraviolet light, all tetra-
Carcl 1/2 aroxysilanes give a light blue or dark blue as well as a violet fluorescence.

The present work x~as concerned with the effects of
stirring on the polyrinrization rea'ctions ok acrylonitrile in aqueous
solutions (7,.)), owing to the incrchsing importance of such polymiers
in the production of artificial fibers.* The reactions were carried
out under argon in a cLainlorno stetl autoclave 6 with stirring
(2800 rpm, Ae buing 4000 or 46000),' at 1.5 - 45 0, under isothermal
6onditiono. O-imilax c.-cl)c rime ut s wdre carried out under static con-
ditions?* in air and in argon. Iq-inCi4 and oxalic acid were used as
initiators. In stirrcd sobitions after 15 inin reactions, the
