Abstract: The tests were made with the Pul.-vskaya variety which
belongs to the stock of Ricinus chineassis. The highest
yield was obtained with spacing the plants at 40 X 40 cm
and with the planting times between the- 5th and 30th'
April. Eense spacing of the plants reduced the damage

ABSTRACT-t This is a new typology and classification of avalanches.
The author studied those problems in the middle strip of
the Dzhungarskiy Alatau in Tyan-Shan in 1955/56. That area
has been evaluated as industrially important in the future.
The new classification covers 9,types of avalanches. The
avalanche station "Yukspor" is mentioned by name. The

Influence on the Heat Transfer Coefficient of Liquids

TEXT.
for the-practical calculation of the influence of physical properties of
liquids on the heat-transfer intensity, as well as for thermodynamic
calculations of chemical apparatus, is analyzed in this paper. The
following conclusions were drawn from this analysis: 1) The calculation
ofthe influence of physical properties of liquid.s on the heat-transfer
intensity, customary in publications, which starts from the functional
dependence of the Nusselt, Reynolds, Prandtl and Grashof criteria, shows
that the Nusselt index increases with an'.Increase of the Frandtl number
(Pr) and constant Reynolds number (Re). The increase of the Pr n'Umber is,
however, correlated with an increase of the kinematic viscosity)). This

Transfer Coefficient of Liquids
leads simultaneously to a decrease of.the Re number. The ai'.Itual consumption
of liquid must', therefore, be increased to warrant Re --cointst. A calcula-
tion made in this way-of the influence of phyaical:parametors on the hea't-
transfer coefficient is not justified in practical calculations.
2) Thermodynamic calculations of chemical apparatus: a) At a given size of
the apparatus, the liquid consumption can directly be calculated from the
equations for turbulent and laminar flow at Pr = const., since the flor,
velocityis only conta-ined in the Reynolds number. b) For the calculation
of the influence of physical properties on theheat-transfer coefficient,
the index equations for turbulent9 laminar, and free flows are to be
brought into the form c4 = f(Pr-n) or 0( = f,(Pr-m), at a constant con-
sumption of liquid and equal d. From equations.s Iolved according to the
heet-transfer coefficient o~, it follows that an increase of the Prandtl
number reduces the intensity of heat transfer at the same flow velocity

ABSTRACT: The Institute of Automation and Telemechanics of the Ac.
Sc. USSR (Institut Av-tomatiki i Telemekhaniki Akademii
Nauk SSSR) convened in October 1957 an All Union
Conference on the theory of reiay systems. The aim of
the conference was to evaluate thepresent state of the
problem of the theory of relay operation, particularly
evaluation of the problems of synthesis, analysis and
transformation of the structure of relay equipment,
optimum construction and assembly of such structures,
automation of the processes of synthesis and analysis
of such structures. Over 330 representatives of research
establishments, works' laboratories and project organisa-
tions from numerous centres of the USSR as well as
scientists from Roumania, Hungary and Czechoslo-valcia
Participated in the conference.

TEXT3 By way of introductionp the authors refer to an investigation carried out
by V. V. Korobkov at Moskovskiy gosud4iretvennyy. univer" itet (Moscow State
University) in which ii is shown that automatons for traffic regulation, which
meet the requirements of modern traffic, are very complicatedu It was necessary
,to build a device for the proper choice of control algorithms. Such a device
was designed at Gorlkovskiy gosudarstvennyy umiversitet (Gorlkiy State
University), and its"mode of operation is described in the article under review.
-First, the main elements of traffic on a crossroad are explained, and the
traffic itself is divided into three groups according to the direction and
change in direction on the crossroad. Furthermore, the geometric conditions and
the control algorithm are referred to as being the main elements of traffic on
.11~
a crossroad* Here, the six control algorithms shown in Figs 1 are discussed,

eaoh,of which is aasumed to hold for some time. In order to be able to observe
the-traffic with a given control iklgorithm, the device mentioned above was built.
The authors chose a type oforossroad at which two two-way roads meet, and it
was assumed that.regulation be carried out by means of a four-point traffic
light. The control circuit is illustrated in Fig. 2. Random traffic events are
simulated here by means ef iight buzzer gererators which indicate the vehicles
the crossroad by.emitting pulses. Eight counters count the vehicles
which areindicated by fifteen ligHts. The control algorithm in realized by a
special programing device. The co 'd:es are transformed by a device which also
processes information. Digital computers may be used for these two devices. The
observer's desk is shown in Fig. 3..There are 3 figures.

The authorsIthen offer a definition of a self-correcting circuit, ac-
cording to which, in the case of any troublep the circuit V is realized
by the same function as the circuit X. The question is raised as to
whether such circuits exist at all, and it is shown that a aelf-correct-
ing contact circuit can be set up for any function f(xi, ... Xn). These
circuits, howeverp are very complicated, and reference is made to first
results reached. by Potapov under restricting premises. A more general
solution of the problem is dealt with in the present article. The au-
thors define a function LM(n) which characterizes the complicacy of a

circuit. This circuit is based on the premise being described by a
function J(x 1'...Xn) and of being self-correcting in the case of short-
circuits in m contacts. Theorem 1 is set up and demonstrated, an4 ac-

of many of the lemmas,, and some of the reasoning isborrowed from Fost18 work.
However, in an effort to simplify the presentation, the authors obtain a structure.
for closed classes of logic algebra functions which Is simpler than Post's.

AASTRACT: It is assumed that a junction transistor at high frequen-

The equivalent circuit is employed in the analysis'of a
grounded base oscillator which,contains a resonant circuit in
its collector (see Fig'.3) and in which the feedback to the:
emitter is provided by means of a coupling capacitor Cc
It is assumed that the. condition of oscillation requires that
the input admittance of the transistor plus feedback circuit
be equal to the admittance of the resonant circuit (see Fig.4).
It is shown that this condition results in an oscillation
