Abstract : The authors describe the new more efficient method and
equipment for the overlapping multiple-thread milling
of small outside threading on automatic and semi-
automatic machines. The new method has been developed
by the Experimental Scientific Research Institute of
Metal Cutting Machines (ENIMS). Seven drawings and

TITLE: The Ways of Decreasing Labor Consumption in Stoping
Operations at the Dzhezkazgan Mine (Puti anizheniya

PERIODICAL: Gornyy zhurnal 1959, 'Ir 1, pp 23-2B (USSR)
ABSTRACT: The deep blast hole mining system, which was intrDduced five
years.,ago in the Dzhezkazgan mine, is analysed in the article.
The results of the experimental delayed and instant blasting
operations are compared in the form of tables. The author
studies the yield of various rock sizes and their variations;
the results of these studies are illustrated by graphs.
The author reaches the following conclusions; A better crush-
ing of the ore can not be obtained by shortly delayed blasting.
Reduction of labor consumption in stoping operations can be
obtained by decreasing the diameter of blast holes to 70 mm,
and increasing the conditional lump size to 800 mm. The
introduction of a 100 cu m scraper cculd double labor pro-

Abstract Energy of decomposition of vegetative residues in the
soil can be lowered vhen oxidizing proce8ses prevail in
it, and this is achieved by a temporary moistening of the
soil. A liberal wetting of vegetative residues as soon
as the plants had withered consequently irp,-ded their
aerobic decomposition and mineralization if oxiaizinG
processes predominated, and this led to an accumulation
of hunus in the soil. M.L. Yaroshenko

The initial system of equations consists of the equations of
the magnetohydrodynamics of an ideally conducting liquid,
of ~he Maxwell equations for the field, and of the boundary
c*onditione for the parting planes. In equilibrium, the pressure
Po of the plasma is assumed to be balanced by magnetic forces
(caused by the currents flowing on the plasma surface).
This is vhy the plasma is homogeneous with respect to 9 and
z, the velocity is equal to zero,'and only' the components
H 0 and H0 are different from zero. Within the plasma,
Y Z
Ho is assumed to be equal to 0, and Ho is assumed to be
I? Z
homogeneous everywhere. The deviations from the state of
equilibrium are assumed to be small, and the equations are
solved by the standard method. This produces rather an ex-
tensive dispersion relation for the determination of the

spectrum of the frequencies of the system. The also rather
extensive criterion for the stability is then indicated.
Without closely investigating this stability criterion, only
the conditions for the stabilization of tho 2 most dangerous
kinds of disturbances with m - 0 and m - I are investigated.
It is assumed that there is no external metallic wall. These
calculations lead to thu following results: At 62 - 1, the
stabilizing fi6ld, in the case of a hollow cylindrical con-
ductor, is smaller by
r~1(62 q-1/2 times (at h 0) and by ,(62 _ 1)- 1 times

(at hz3 0) than the field required for the stabilization
of a compact conductor. There are 4 references, 2 of which
are Soviet.

The Influence of Ron-elastic Collisions Upon the Electron Velocity Distribu-
tion multiplied by n, and the recombination (volume recombination
under high and surface recombination under low pressure), res-
pectively. The collisionscf second kind are ignored, only mono-
atomic molecules being considered.-In..the,-caseikmpolyatomic
molecules are considered i the excitation.of the vibrational
rotational levels of the molecules and the dissociation must
be taken into account, which can be.done.in a similar way. The
expression for-Sta has the usual form,-an-approximation model
being used for the non-elastic collisiQns. The term St has
been introduced in order to maint4in-the-number of particles.
In the steady case this term is esnential.-The calculation is
given step by step. An exact solution-af-the equations-thus
obtained is impossible, only an approximate one being feasible.
The expressions found hold for the case-of a single tonization
(N-1) and.of only one excitation level. These results may,
however, without difficulty be generalized to arbitrary 14 and
M. The assumption of nonelastic collisions entails a sharp
decline of the distribution function for u > 1. The mean
electron energy first increases with growing electric field
strength and then remains constant (from a certain value E-E(N 0))

losses. From this point onward the mean electron energy in-
creases again. In the last section the generalization of these
results (concerning the distribution function) to the case
of an alternating electric field is discussed. The author

ABSTRACT: A theoretical analysis was made of the spectrum
of the longitudinal oscillations of an electron-ion
plasma for the case of high temperatures (Maxwell
distribution). In the case of a homogeneous
plasma the asymptotic form of the potential as the
fundtion of time was taken to be:
D(p,k)~O (p iw - 1).

spectrum of longitudinal oscillations of plasma
is represented by two branches: optical and
acoustical. The relative decrement of damping in
optical oscillations is very small. In the case
of the low-temperature plasma.. the acoustical
oscillations are also practically continuous. With
high-temperature plasma the weakly damped acoustic
waves are possible only at sufficiently high ratio
of T,,,/T,. V. L. Ginzburg, M. S. Rabinovich, V. P.
Silih, And A. A. Rukhadze participated in the
discussion of this work. There are 6 Soviet references.
