ited on the cathode with constant D.,-and permitted an increase in the
activity of the metal in the deposit and increased the general yield of the
metal from 25 to 75%. The construction described can be used only if the
depositing dendritic crystals are plastic, as, for instance, the crystals

TM: The authors describe the design of a laboratory ara-melting furnace,
suitable for remelting Zr and the production of its alloys. In this furnace It
is possible to perform melting with both consumable and non-consumable electrodes,
on a-a or d-o (the latter is preferable because of the aro stability in this
cage). An inspection of the me;hanioal properties of Zr and Cr specimena pro-
duced showed very slight contamination of the metal during me3ting 'up to 0 01% W
and 0.03% Cu). The furnace Is equipped with a hermetic melting chamber with a
water-cooled W-orualble. A povier connection with a non-consumable tungsten
electrode is top supplied to the chamber; its motion does not disturb the herme-
ticity of the chamber. The crucible has exchangeable bottoms to obtain different

TEXT: Thermal dissociation of Iodides was conducted by the Van-Arkel scheme.
Sublimated iodine was introduced to the apparatus without violating the vacuum.
The process was conducted In a small-size glass apparatus with a branch serving to
establish the vapor pressure. Industrial cubic-shaped fib, transformed into chips,
was used as initial raw material. Of three parameters (filament, branch and re-
'tort temperature) only one was varied In the experiment, while the other two re-
mained constant. The filament temperature was 9000C In all the experiments; tile
retort temperature varied from 350 to 7000C. It 0was found that the rate of fib
deposition, at a temperature variation up to 600 C, increased monotonously with
higher temperature of the branch piece (under these conditions NbI 3 Is stable).

TEXT: The paper describes an extension of experimental work on the precipi-
tation of Mo by thermal dissociation of MoClr_ from the gaseous phase on a W_#la-
rnent core in a modified van Arkel apparatus-(cf. no.1 ~; subject sbornik, MIP$
1959, 70). The specific objective of the present work ;I a determination of thi,
effect of the halide-vapor pressure in the retort, the t~inpcrature of the filampt,
and that of the initial, "raw," metal on the rate of growth of the wire. The Pyop-
erties of MoC15, Moc'4, MOM 31 and MoCl Z are briefly summarized from pasting
standard Soviet and U.S. textbooks. Lathe-produced Mb shavings, d, 4
by hot-
HC1 treatment, washed in distilled water, dried at 110- 1200C, and degassed!a't

equipment for the production of the MoC15 is described in no.Z of the present'
sbornik, Atomizdat, 1960, 55. The thermal-dissociation equipment is described
(with 2 cross -sections). It comprises a glass retort with a filament holder and an

extension neck through which the MoCl is introduced from an ampoule. A current
of up to 50 amp could be passed througk the filaments for T-control purposes. The
various types of glass employed at the various retort T's are specified. In all tests
the neck T was lower than the retort T, so that excess MoCIS was precipitated in
the neck and the required vapor pressure could be established in the apparatus by
altering the neck T. The precipitation rate was determined by the rate of growth
of the wire radius per unit time. as expressed in terms of the Z/3 power of the rate
of change of the wire-heating current. The neck-T range investigated extended from
40 to ZOOOC. Two marked maxima were observed at neck T of 100 and 1700C; the
T of the maxima remained the same for 3 combinations of retort T (300 and 4000)
and filament T (1,300 and 1,4000). At a filament T of 1,4000C and an optimal neck
T of 1000 an ill-defined maximum occurred at retort T of 300-4000; within this
T range low-volatility lower chlorides formed which interfered with the pyrometric
determination of the filament T. The increasing growth rate with increasing retort
T from 100 to 3000C is attributed to- (1) Accelerated reaction of the combination
of the free Cl into MoC15 at the surface of the raw material, and (2) accelerated
diffusion of the MoC15 thus formed toward the filament. Beyond a retort T of
3000C, the MoC15 begins to dissociate into MoCI ' whereupon the partial pressure
of the MoC15 decreases and the precipitation-gro3~th rate diminishes. At a neck
T of 1000C and retort T of 400 and ZZOO the growth rate increases steadily at

TITLE: Growing of molybdenum single crystals and their properties

ABSTRACT: For the majority of low-melting point metals the methods of growing
single crystals are well established and described in the literature. On the
other hand, growing of single crystals of high-melting point metals, such as Ho',
W, Cb, and Ta, presents some experimental difficulties. In this connection, the
authors tried to grow molybdenum single crystals from the gaseous phase of an
appropriate compound by the method of thermal dissociation. An bases for de-
position, single-crystal filaments 0.1 mm in diameter were prepared from poly-
crystalline molybdenum wire by recrystallization, applying heat at 1550-1650C for

4-5 hours.. Such monocrystalline filaments could be obtained in 10 to 90 mm
lengths. The method and test equipment used are described in the paper of V. So
Yemel'yanov et al. (Yemellyanov, V. So, Leontlyev, Go A., Yevotyukhin, A. I.:
"Metallurgiya i metallovedeniye chisty*kh metallov," vy* p. III. M., Gosato-
mizdat, 1961, str. 137). The subsequent growing of crystals was performed from 1
the gaseous state of MoCIS at temperatures of 1500-1600C in the beginning of the
process, and then at 1280-1300C. A higher rate of deposition occurred at the
higher temperatures. Molybdenum single crystals were grown up to 3 mm thick and
90 mm long. The single crystals obtained showed high ductility at room tempera-
ture, could be easily bent to a large angle and cold-rolled. In contrast to
this, polycrystalline deposits obtained from the same gaseous phase were brittle
in bending. In addition, tests were made to determine hardness, modulus of elas-
ticity, and internal friction values of molybdenum single crystals. The hardness
of molybdenum single crystals was considerably lower than that of the commercial
metal. The microhardness of monocrystals was 180-200 kg/mm2 (under 200'gr load)
while that of the common commercial metal in an annealed state was 230-260 kg/;A
The modulus of elasticity was determined from'resonance frequencies of flexural
vibrations of freely suspended cylindrical specimenso Single crystals showed
somewhat higher Z value* than samples of commercial metal. The internal friction-
was determined from the dastping of flexural vibrationso Quenched single crystals

showed low values of Internal friction. After a slight plastic banding defor-
mation,.a considerable increase of internal friction was observed. In plastic
bending the number of dislocati~ms increased, causing an increaso of internal
friction. When a crystal contained an abundant number of points of disorder
subject to fixing by quenching, the latter might migrate to the dislocations and
fix them, decreasing thus the level of Internal friction. Orig. art* has: 5

,TRkNSLATION: The article concerns an investigation of oscillatory movements of the
,earth's surface caused by the action of loads In the form of atmospheric pressure
and precipitations. Having used materials of experimental investigations by TsNII-:
GA6iK fc-entral Scientific Research Institute of Geodesy, Aerial Surveying and i
.Cartography7 (RzhAstron, No. 7, 1957, 6129) and the materials of first-order level-!

responding,values for atmospheric pressure taken from synoptic charts, the author

.concludes that in all cases a relationship between the change in elevations and the,
I
Yariation of atmospheric pressure is detectable. This conclusion is based on
!graphics, constructed by the author, on which are plotted differences in atmospheric
!pressure when running direct and reverse level lines along the sections and varia-
itions in elevations for these same sections while conducting traverses in different,
Idirections.'
Considering the role of precipitations, the author concludes that oscillations!
iof the level of ground waterso which are closely connected with the amount of pre-
icipitations, can cause a change in tilts of the earth's surface for different per-
iiods of levelling operations. Similar changes of anthropogenic origin are.noted
repeatedly in literature. 7he magnitude of the oscillations having natural origin i
i I I
i(with different cyclicity) is difficult to establish because of the lack of long-
item data relative to oscillations in the levels of ground and subsurface waters.
lHowever, there is basis to assume that this value can be considerable.
The author's general conclusion is that external loading on the earth's surface
,and oscillations in the level of ground and subsurface waters are one of the prin-
icipal interdependent factors of modern movements of the earth's surface and there-
,fore exogenic movements of the earth's surface must be excluded from the results or"

~ABSTRACT: It is pointed out that conformity of rates of recent vertical movements
jof the earth crust, as obtained from results of repeated levellings with qualitative
"indexes evolved on the basis of geological and geomorphological data, is considered
las a confirmation of the tectonic character of the movements. The author formulates
and expresses the position that results of repeated levellings reflect not only the
fluence of tectonics, but also the effects of such external factors as modifications
t
I
:of the atmospheric circulation patterns and, particularly, the variability of under-
1ground water level. This leads to the conclusion that the effect of crustal movements
'conditioned by exogenous factors should be isolated and considered when attempting
Ito derive reliable valuca of current tectonic movements in platform regions. Possible
l,w,-ys to effect the suggested approach are enumerated.[Translation of abstract)

TITLE: 'Contributionto---i"Fe-Consi d era tion of the Shear Deformation
and the Rotational IneXtia of Cross-Sections in the
Theory of Oscillation f Non-Prismatic Bar&j~o

ABSTRACT: In his book on the theory of vibrations S.P. Timoshenko
took into account the effect of shear and the rotational
inertia of the cross-sections in the transverse vibrations
of prismatic bars. These two effects have been taken
into account only approximately in the theory of vibrations
of bars with variable cross-section. In the present paper,
a direct solution is given of the appropriate system of
equations for the case when the coefficients of the
equations are expressed by a power function of the length
of the bar. (With different exponents for the moment of
inertia, radius of gyration, mass distribution and
Card 1/3 equivalent cross-sectional area). The equation of motion

Contribution to the Consideration of the Shear Deformation and the
Rotational Inertia of Cross-Sections in the Theory of Oscillations
of Non-Prismatic Bars
is adopted in the form given by Timoshenko for the bar
of constant cross-section. Equally, two solutions are
postulated in the form of functions of length multiplied
by a sinusoidal function of time. The free vibrations
of the bar are first treated. The functions of length
are found to be power series, whose convergence has
already been studied by Mikeladze, Sh.Ye. (New Methods
of Integration of Differential Equations, Moscow-
Leningrad, 1951). Forced oscillations with a forcing
function expressed by the product of a function of
length and a sinusoidal function of time are analysed,
The same form of solutions as before is assumed. If the
length function in the forcing function is also a power
function, the solutions are power series. The proposed
method does not require a prior determination or
approximate assumption of the fundamental oscillation
Card 2/3 mode of the bar. The mode of the deflection is derived

Points out importance of recent report that a
certain species of tick has survived prolonged
starvation for nearly 5 years. Ticks are min
carriers of relapsing fever. If these ticks
also preserve spirochaeta. in their bodies, any
place could become a source of relapsing fever
after many dormant years. Gives tabulated starvation
data for various ticks.
