ABSMCT: In this paper, the influence of the correlation between
the electrons on the electron distribution in a narrow
admixture zone and on the electron distribution according
to quasi-momenta. The Investigation is started from the assum-
t1on, that only electrons situated in one admixture centre
May interact with each other. From the result obtained,
(equation) It can be seen# that in the case of A4 - 0 (no
correlation) the ordinary statiotl formulas by Fermi-Dirac
(with an exactitude including AVZ) are obtained. In the
case of Aw- co,(inflaite correlation, implying the
absolute Impossibility of finding two electrons In one

of the correlation between electrons on the kinetics of
processes in the narrow admixture zone will be conducted by

ABSTRACT: The properties of the electron gas in a Larrovi impurity
band, and in a semiconductor with such a band, are
examined using the effective mass method to calculate
the chemical potential. State distribution densities
are given for cubic and body-centred lattices, plus the
temperature variation of conductivity for various degrees
of narrow-band filling, and for various energy gaps
between the impurity and conduction bands. The theoret-
ical treatment follows that of Ref.(3) only the results
for the body-centred case being given ?j.n deriving the
equations for the chemical potential). Detailed
consideration is then given to the model in Figure 1;
it is shown that the Coulomb repulsion between two
electrons on the same atom cannot be neglected if the

ABSTRACT: Im the present work previously obtained results were
utilized for the purpose of deriving the formulae for
the electric conductivityp the constant of the Hall
(Kholl-) effect, and of the thermoolectrocotive force
in semiconductors with a narzow impurity zone. Results
obtained are compared with experimental data (references
4 and 5). The following model served as a basis for
calculations: A monovalent admixture was investigated, the
electrons of which aro distributed over the levels in the
narrow impurity donor zone which is in the conductive
zone. It was taken into account that a certain part of the
Card 1/3 electrons is in the compensating admixture. The valence

a change of the width of the narrow impurity zone the
inclination of the curve in lno, Idoes not change. What

changes are merely the values of conductivity. In the
temperature interval of from 20 to 60K the narrow impurity
zone exercises no influence upon the course of the
temperature of the Hall (Kholl ) constant. The reduction
of the Hall constant within the temperature range of
Card 2/3 5 - 3,50K is connected with the fact that within this range

ABSTRACT: Anomalies In the electrical., galvanometric and other properties of
emiconductors are often du6 to aetrrow inurity bands, vid this article treats
the statistics of an electron gas in such bands. Since energy spectra are de-
termined only for the edges of the narrow bands# methods of treatment based on
effective masses cannot be used, A formula was derived for the calculation of
the statistical sun, the chemical potential and the number of states In a bend
with energy equal to or less than a given energy, epsilon, and a density-of-
states distribution within the narrdw band for substances with a face-centered
lattice.

ABSTRACT, East German glass foam (usually used as ullill me terial) was found
to be unsuitable as a lubricgat In steel extruslonj~hgNred alone owing to a
high content of allicl;n-dioxide and carbon, the letter originating from the foaming
medium. However, it was found that the same glass foam is an excellent carrier of
other IL:,ricants such as glass powder. Foam-glass disks 73 mm in diameter and
2-3 mm thick containing pores 0.1--4.0 mm in diameter were rolled in glass powder
so.that the latter filled the open pores.' Then the disks were used in a regular
manner in the extrusion of carbon steel at 1100C with a reduction of 82-96.5% in
a vertical 300-ton press. The extruded bars had a perfect surface and accurate
dimensions, and the service life of dies increased by 75%. Since regular glass

ABSMCT: Natural oscillations of the armature of an electromagnet with
a coil connected in series with a capacitance to the terminals
of an AC source are considered. When pulled in the armature
stretches a spring which, when the pulling in is finished,
brings It to the Initial state again. The reciprocating motion
of the armature repeats with a regular periodicity, as the
feeding voltage remains constant. From the study of experimental
dynamic traction characteristics it follows, that the force for
pulling in the armature is greater than the releasing force;
Card 1/3 consequently such a system is able to perform a useful work while

pulling in. On the basis of an analysis of equations and experimental data,
it k*-a found out that the ambiguity of dynamic characteristics can be physi-
cal-'. explained In principle by three overlapping phenomena; the oommentsur-
ability of the time of motion of the armature with the duration of translent
processes; the presence of a speed component of electromotive force; the
presence of natural oscillations in the electrical part of the system. The
natural oscillations almost do not manifest themselves separately from pulsa-
tions caused by the motion of armature. They only appear at a sharp stop of
the armature. In the case of absence of friction and restrictions In motion,
the frequency of mechanical oscillations of the system depends on the mass
and rigidity of the spring only, and the amplitude of oscillations deperds Ork
the electric network parameters. In presence of armature motion restrictors V
the frequency increases with a decrease of the possible amplitude, and the
dependence of frequency on the network parameters begins to show up. Because
of an Interrelation of electric and mechanical parameters, the conception of

TITLEs A New Contact Machine with Stored Energy (Novaya kontaktnaya
machina a nakoplentyem energii)
PERIODICALe 3varochnoye Proizvodstvo, 1957, No 10, PP 7-9 (USSR)
ABSTRACT& The new contact welding machine is a welding transformer de-
signed collectively, by the three inventors (authors' certific
ate No.106207) at the Chair "Electrical Engineering and Elec-
trical Equipment" of MVTU imeni Bauman. The essence of the
design consists of a movable central core rigidly connected
witt resilient elemgnts (these were springs in the experiment-
al unit shown by Figure 1) which contract under the pressure
exerted by the core when current passes through the transforms,
windings. In this way, energy is stored in the magnetic field
and in the springs. When the primary circuit is interrupted,
the magnetic field weakens and the springs repel the core,
whereby a portion of the energy stored in the springs is trans,
ferred into the welding circuit. The article Includes a
mathematical analysis of the system. The work by A.I. Hook-
Card 1/2 vitin (1) was utilized by the authors in their investigation oi

the processes connected with the movements of the core. The
conclusions are made thai the system stores and gives into the
welding circuit 1.5 tp 2 as much energy as a transformer with
a stable core (at equal mass of material used for building the
traneformern). It enables control of the welding current im-
pulse shape and the speed of energy increase which is converted
into welding heat between the electrodes. It decreases con-
siderably the are formation on the contacts being led &part,
and results in better uniformity of quality of the welding
spotag which eliminates a serious drawback of existing machines
which store energy In the magnetic field alone.

Abstract Observations of egg development in Petri dishes with an
agar nutrient mediun showed that the development at 200
is better than that at 29 and 370- Eggs on thicker me-
dia (2f agar) develop more rapidly than on thinner ones
(0-4 agar). 100% hunidity favors development of Tricho-
cephalus eggs, but limits development of Ascaris eggs.

In the present account the authors relate the results of mycological researches
effected on a series of species of blastosporif e rous fungi, isolated from cases of
vulvo-vaginitis. The majoritv of these fungi (55.559) belongeo to the species Candi-
d3 trapicalis. A small number belonged to the species Candida chalmersi
and only 33.31ro to the species Candida albicans. The Candida. tropicalis is general.
ly considered to be a pulmonary parasite and was found with unexpected frequency
in the vaginal mycoses. The vaginal habitus of the species Candida trapicalis has
not been described heretofore. (Yeasts and pseudoyeasts may also be present in
the non-diseased vagina. It is necessary to distinguish between candidiasis being
causal or merely present. Ed.) (Xlll. I())
