TEXT: This is a direct continuation of previously published work
(Ref. 1: This publication, 141-165) using the same materials and
methods. It is concerned with the properties of the U-Mo-Zr system
at lower temperatures. The isothermal sections at 6000, 5750 and
5000C are graphically presented along with the chan es of hardness
and lattice parameter for the sections with 70%, 60P6, 50%, 40% and
20% at.-% of U. The polythermal sections of the following constant
compositions are graphically presented: a) Zr : Mo = 1 : 3; b)
Zr : Mo = 1 : 1; c) 70% U; d) 60% U. A projection of the phase dia-

gram of the triple system U-Mo-Zr on the concentration triangle
and
the two binary diagrams U-Mo and Zr-Mo are given. A full scheme
of
the mono- and invariant transformations in the triple systems is
presented diagrammatically. The main conclusions which follow
per-
tain also to the preceding paper (Ref. 1:0p. cit.). It is stated
that the simultaneous solubility of Mo and Zr in U is greatly
li-
mited by the formation of ZrMo 2 (E -phase). Therefore,
ther-phase
triple solid solutions exist only in narrow stripes along the
bi-
nary systems U-Zr and U-Mo. The isothermic sections were
revealed
to be fairly complex, in particular in the 675 - 5750C range,
owing
to the presence of intermediate phases and ZrMo 2* It was
possible
to establish the regions of the existence of homogeneous
X--solid
solutions. In the 675 - 65000 range a new phase ~ 3 is formed,
hav-
ing a peculiar lattice and high hardness. This phase exists
down to
55000. 0,11 the basis of 9 isothermal and 4 polythermal
sections, the
polythermal diagram of the U-Mo-Zr system was constructed for
the
first time in the region of the solid-state transformations. 31

monovariant, 3-phase equilibria and 11 non-variant, 4-phase
equili-
bria were revealed. The most important element of the diagram is
the surface limiting the r-solid solution region from the high Mo
and Zr concentration side. The constructed diagram, together with
the transformation scheme, are very important for determining the
characteristics of the alloys in the system. The volume-centered
cubic solid solution U-rioh (r) or Zr-rich (rZr), changes the
lat-
tice on quenching, in the first case to a lattice ofo~-uranium,
in
the second case to that ofo~-zirconium. In samples containing
more
of the alloying element, another phase, (0), having a hexagonal
lat-
tice is formed. Annealing over 100 and 1000 hours of alloys
quen- V/
ched from 10000C has shown that the (--phase cannot exist after
hardening and prolonged maintenance at 5000C. As a result of the
de-
composition of the r-phase a special state arises, either a one-
phase (~4 ) state or a mixture of four phases. There are 15
figures

TEXT: The question of the)r-solid solution stability at
relatively
low temperatures is one of 'the important problems in studying
the
alloys in the U-Mo-Zr system. If the r-solid solution
decomposes,
exposure of alloys having a high hardness is equally important.
The
investigated alloys are shown in a figure as well as the lines
of
equal hardness of the alloys, hardened from 10000C, showing the
si-
multaneous or separate influence of.the alloying elements on the
hardness. Curves of the hardness change are given for the alloys
quenched from 10000C, and annealed at 5000C for 100 and 1000
hours,
for the following sections:-Zr -. Mo ratio = 1 : 1, 3 : 1, 9 : 1

and for sections having constant U at.-~ of 90, 70, 50, 40, 30,

alloys
previously quenched from 100000 has shown that the r-solid
solution
cannot exist for prolonged periods at 5000C in the IJ-Mo-Zr
system.
The r-solid solution decomposes either into a single different
phase or into a mixture of 4 phases. After the
1000-hour-annealing,
the highest hardness (550 kg/mm2) was found in alloys having 10
at.-% Mo and 60-30% U. There are 8 figures.

TEXT: Unalloyed uranium is not suitable for use as a reactor
fuel
because of its low strength above 5000C, change in dimensions
and
knoll formation at cyclic loads, low corrosion resistance and
easy
oxidation. Zr and Mo are drawing attention as alloying elements
owing to their high solubility in a7U and their strong
influence on
the structure and properties of U alloys. The alloys
investigated
were prepared in argon. For microstructural investigations the
al-
loys were etched. Unfiltered 4-Fe radiation was used for the X-
ray analysis. The hardness was measured by a diamond indentor at
10 kg load on a T11 (TP) apparatus. The alloys were annealed at

ABSTRACT: In order to obtain a suitable variable-capacitance diode
for use in microwave amplifiers, an.attempt has been made to produce
an alloy diode with variable capacitance and maximum Q, since maxi-'
mum Q and maximum bandwidth are among the main requirements that
must be satisfied by such a diode capacitor. As a result of com-
bined calculations and-experiments (for maximum impurity concentra-
tion) have shown that the germanium used for diodes with variable

capacitance and alloy contact should have a specific resistivity
0.02 ohm-cm. Such diodes have a time constant not larger than 1.5
nanosecond, and their main shortcoming is the relatively lowbreak-
down voltage (3--3.5 V). An equation is derived for the 0 in terms
of the impurity atom concentration, the contact potential differ-
ence, and the diode inverse bias. It is shown that an optimal int-
purity concentration exists, from which the optimum resistivity is
determined. Orig. art. has: 9 formulas, and 1 table.

proposed. Enclosure 1 illustrates the seque*nce of operations. Al
is sprayed on
P-Ge through a stencil with rectangular holes 30 x 50 or 50 x 100
microns. In a
hydrogen furnace, Al is fused into Ge. An Al" 0, film is sprayed
under vacuum
over the entire Ge surface. The billet is again placed into the
hydrogen furnace
and heated to 660C which results in an insulating film covering
the.Ge surface,

TEXT: The diffusion coefficient of nitrogen in oxygen is deter-
mined, at a temperature.of.67.80K, by the method of the gas phase.
The method.consists in adding-an-amount of nitrogen vapor to the
oxygen vapor which was in equilibriuaLwith.the liquid. By the rate
of pressure-change which follows the dissolving of the vap-or, the
diffusion coefficient can be calculated by the formulas

TITLE: Irrigation.Conditions in Semidesert Alkallne Steppe
PERIODICAL: Gidrotekhnika i melioratsiya, 1959, Nr 9, pp 3-9
(USSR)
ABSTRACT: Irrigation of semidesert alkaline lands began only
in recent years. In this connection, the necessity
of an adequate irrigation system came to the forefront.
To this end, the S -talingrad_Agricultural Institute
founded, in 1950',--a-specidl Chair for studying irri-
gation methods for raising corn, tomatoes, cabbage
and sugar beet on steppe land. Experiments were car-
ried out in the area located 20 km south of the Volga-
Don canal imeni V.I. Lenin. The soil in this region
is clay with a large percentage of deposited carbo-
nates. It is compact, has a low porosity (about 40e,),
Card 112 and a low water permeability. For all cr 0ps the

ploughing was made to depths of 20-25 cm. The irriga-
tion was performed by means of furrows, The soil
moisture was maintained, depending on the kind of crop)
within the limits of 65 to 851,' of the total absorbent
capacity of the soil. The best conditions for growing
crops were established as follows: tomatoes - soil
moisture required during the vegetable formation -
80 to 85'~,, otherwise 70 to 751-'; cabbage - 80-85% du-
ring the whole vegetation period; sugar beet - 65-80%;
corn - 70 to 75~. The soil moisture was determined at
depths of 0,,6 to I m. The harvests yield sharply de-
creases in case where the soil moisture, due to in-
sufficient watering, drops below a certain predeter-
mined rate. ExperienCe has shown that for soilsi
considered in this article, the most favorable rates
of watering were: for vegetables 350 to 400 cu. m.;
Card 2/2 for sugar beet 400 to 500 cu, m.; for corn 600 to
700 cu. m. a hectare. There are 7 tables.

from average temperatures are believed to be caused by
disturbances in the InterrelationshIp between air circulation
and-thermal conditions at the surf'~ce layer of the atmosphere.
The entire article is divided'into three chapters each-treating
one separate'factor causing the'occurrence of anomalies. In the
firbt.'Ir-ohapter, G.I. Morskoy states that the horizontAl
transfer
of air masPes.is the main factor in the formation of-average
temperature anomalies. He also deduces the ratio between the
zonal circulation of the atmosphere and,the general thermal
conditions of the-atmosphere. The author suggests a new
mathematical approach in calculating the mean monthly
temperature
anomalies for.absolute topography at the 500 millibar level. In
Chapter'2, V.G. Semenov analyzes the influence of the surface
layer of the atmosphere on'the transfer of air masses and'how
this transfer causes the occurrence of anomalies. In the third

of this transfer of air masses to te'mperature
anomalies. The
meridional and latitudinal circulations are calculated
for a
number of regions and altitudes in the Northern
hemisphere.
The.number of focuses on the Soviet territory, where
large-
scale anomalies are formed during the three winter
months, is
found to fluctuate'between 2 and 4. This article is
based on
the results of an analysis.of 8 forecasts made on the
25th of
each.preceding month, for December, January and
February of
1955-57; Data on forecasts .were compiled separately
by three
different bureaus of-the Central Institute of
Forecasting
viz., the long-term prediction division (ODPP), the
division of dynamic meteorology (ODM), and the
division for

Character of Meridional Circulation of Air in Europe and
Western Siberia. 181
The circulation of atmosphere in the Arctic was studied
by
B.P. Mul'tanovskiy. He concluded that the polar region
is not
a solid high-pressure zone, but, contrary to previously
i~xpressed opinions, is composed of a number of cyclonic
and anticyclonic areas. Other Soviet scientists, namely
B.L.
Dzerdzeyevskiy and L.A. Vitel's confirmed
Mulltanovskiyls
theory and proved that all circulation phenomena such as
occur in moderate zones, exist also in the polar zone.
The
present article analyzes the effect of.air circulation
in
the polar area.on the behavior of meridional processes,
carrying cold arctic air masses to temperate zones and
thus
bearing dire'ctly on changes in weather. Consequently,
any
weather forecasting in the moderate zone must account
for
meridional processes drifting in from the North. The
author

examines four possible types of thermobaric fields In the
tropo6phere over the,Artic and also a number of
variations.
Maps accompany this analysis and provide data nn
absolute*and
telitive topography at 500 millibar level for all the
types
involved. The author concludes that a certain definite
character of the baric field in the Arctic produces a
definite
type of meridional movements and that thermal conditions
of
air masses In the Arctic are good indices for the
developing
synbpiic-~. situation in the moderate zone. There are 11
tables.,,
22 maps, and 17 refe~rences, of which 13 are.Soviet and
4 are

in

Py the "principle of similarity" the author understands
an
at,tempt to trace similarities (analogies) in the
development
of two or more atmospheric macroprocesses. The principle
can
be applied.in long-term forecasts when an atomospheric
process
bears a similarity to a process which occurred some time
in
the past but during the same season and in the same
locality.
Card 6/10

Problems in Long-range Forecasting 361
The author analyzes the applications of this principle
and
refers to S.T. Pagova who opposed it and to L.A. Vitel's
who
modified it. The latter worked out a theory of rhythmicit
(rhythmical recurrence) of temperature processes. Vitel's
theory is given in brief, but the author of the artic.le
rejects it. The author establishes indices of similarity
and
demonstrates their applicability in deducing mean monthly
temperatures The data used cover a period of over 50
years
and are derived from 45 unspecified geographical
localities
in Russia shown on an enclosed map. The percentage of
correct
forecasts by the principle of similarity has hardly ever
exceeded 70 percent; on an average it amounted to 63.2
percent.
The author urges expansion of this method of,study and
the
inclusion of localities outside Russia. He suggests
examination
of other factors, such as near-surface pressure, to
which the
principle of similarity could be applied. There are 8
maps,
7 tables and 14 references, of which 8 are Soviet, 2
German
and 4'English.

ABSTRACT:
It cannot be denied that we are still very far from the
solution

of the forecasts mentioned in the title, although
relatively

intensive work has been carried out on this subject in
many

countries during the last few decades.- The method of
correlation

analysis of observations has eventually disappointed
meteorol-

ogists, since it has become clear that good prognostic
correla-

tion8 with a high correlative coefficient were a rare
exception

rather than the rule. It has also been established that
the

parameters which govern and control atmospheric circulation

represent certain functions of time. Thus some works which ap-

peared at the beginning of the 1940'B (Ref 3, Rossbi and

Gaurvits
et al.) were looked upon as opening up new paths,

particularly
with regard to long term prognoses. In them the

hydrodynamics of
the atmosphere for the first time showed their

possibilities in
the latter field. Hitherto relatively extensive
Card 1/3
empirical
data have been collected which statistically evaluated,

permit definite conclusions to be drawn by the ODM (Otdel
dinamicheskoy meteorologii. - Department for Dynamic
Meteorology)
of the TsIP (Tsentrallnyy institvt prognozov = Central Fore-
casting Institute) as to the conclusiveness o~ such forecasts.
The prognoses were made according to Ye. N. Blinova's method,
the calculations according to references 4, 6. On the basis of
several examples the author comes to the conclusion that these
prognoses are of value neither for the work in hand nor for
scientific investigations. The Uchenyy Bovet (Scientific
Council)
of the TsIP has therefore decided to discontinue prognoses bi
means of the method mentioned. However, what has been achieved
along these lines, with the exception of a few prejudices and
errors, should not be ignored. There are two methods which
lead
to the solution of the problem of long term prognoses% a) a
synoptic statistical and a hydrodynamic method. Indi*idual
argu-
ments, the theoretical bases, and'the possibilities foi,
develop-
ment of these two methods were deberibed, and attention was
fur-
ther drawn to the errors which must be eliminated. Some 10
years
ago the author stated both orally and in writing on the
subject
Card 2/3 of Blinova's method that the longest term for a
prognosis is

1-0
Ij V/50-58-11-13/25
On Hydrodynamic Methods of Long Term Weather Forecasts
10 days. For prognoses over a longer period the transformation
of energy in the atmosphere must be taken into consideration,
which (Ref 5) is by no means easy. The science so closely relat-
ed to meteorology - i.e. oceanology - a long time ago came to
the conclusion that turbulent viscosity, both vertical and
horizontal, must be taken into consideration. Friction is here
not only a moving but also a forming power. Modern climatic
theories without due consideration of turbulence are
unthinkable.
The author considers attempts to forecast atmospheric processes
40 to 70 days ahead as utterly senseless if the factors mention-
ed above have been left out of consideration. Six years' ex-
perience with prognoses according to Blinova's method has shown
this with sufficient clearness. There are 2 tables and 6 Soviet
references.

TEXT: There are two ways"of solving the weather forecasting prob-
lem. 1. The dynamic method consists of preparing differential or
in-
tegral equations to describe synoptically known processes. These
equations are then solved with allowance for initial and marginal
conditions. 2. The synoptic-statistical method is based on the
ana-r.
lysis of empirical material in order to distinguish regularities
in the development of atmospheric processes. Two models of
atmosphe-
ric processes -- the dynamic (or physical) model and Stokes'-model
-- must accordingly be created. The problem of the movement of two
V
,-bodies in sky mechanics can s.erve as an example of the first. An

example of the second could be a -as model in which the mean
square
velocity characterizes the initial state. It is shown that the
sta-
tistical approach to forecasting problems should be acluiowledged
as
practically just as perspective as the dynamic. The author reckons
that the statistical apparatus corresponds better to the physical
peculiarities of atmospheric processes. If the course.of a partic-
ular phenomenon is determined by a small number of principal caLl-
ses, dynamic meth6ds can be expediently applied to study it. Bit

two extremes. The statistical method's recognition, however, does
not repudiate the need for using the dynamic method, since the
Phy-
sical concept of atmospheric processes is a necessary condition of
successful weather forecasting. The trend, originally combining
both these approaches and fully utilizing the advantages of one or
u
the other method, appears to be the most perspective. 12 referen-

:PERIODICAL: Meteorologiya i gidrologiya, no. 1, 1963, 9-15
ITEXT: The general principles of information theory are used to
!,evaluate the relative amount of information in a meteorological
field, using a method which is suitable for computer calculations.
iIt is shown how the entropy of a random vector, i.e. a vector whose,
t
1components are random quantities, can be evaluated, and hence a
,rule is deduced for the entropy of the sum of such vectors. Next,
:it is assumed that the vector follows a normal distribution, so
;that the associated probability density is described by a Gaussian
'formula whose argument involves the aatocorrelation matrix of the
!vector. In this case, the entropy can easily be evaluated in a
iclosed form, and the result of this calculation is given.-In fact,
Ith entropy of a normal n-dimensional ve6tor is

where D is the autocorrelation matrix. A formula is then derived
:for the entropy of the direct sum of the two vectors. The direct
.1 sum of two vectors X and Y which are n- and m-dimensional respec-
itively, is the new vector Z = X 0 Y, which is n + m-dimensional,
.and whose first n components are the components of the vector X,
awhile the remaining components are those of the vector Y. Finally,
~these formulas are used to obtain an expression for the informa-
I. In comparing two meteorological fields, the values of the
,field on two charts-nay be compared by this method, and the quan-
:tities to be evaluated are the autocorrelation matrices and the
;mutual correlation matrices of the two vectors made up by the
points on the two charts. The final result takes the form of a
..certain number for I. For example, two charts for which I = 0.20
,represent an analog, while charts for which I is greater or equal
:to unity are encountered rarely or not at all.
