Abstract: The authors have developed the SNEZHINKA (snow flake) unit which
has the following detectors: divided-integrated (d.i.) detectors for testing
parts of cylindrical shape; a d.i. widecut detector; a d.i. detector with
improved parameters, a direct contact-immdrsion detector; and slanting,
miniature and wear-resistant detectors. The detectors are mounted on an
eight-pointed star-shape table and can be used under shop or laboratory
conditions at ambient temperatures between -10 and +40 C.
In 1970 the SNEZRINKA unit underwent shop tests at metallurgical plaats and
the interdepartmental commission recommend it,for series production. The
Elektrotochpribor Plant started using the first industrial batch of
SHEZHINKA units in 1971. A photograph of the unit is given along with
three tables of technical specifications. 1 figure, 3 tables, 9 biblio-
graphical references.

Translation: There are no minor things in the~routine work of pilots.
For an aircraft to function properly pilots must solve the most di-
verse problems, including serving passengers and seeing to prompt re-
pair or complex engineering,lincreasing the effectiveness of use of
aircraft, fulfilling, assignments for,oilmen and geologists, and help-
ing farmers obtain a good harvest...
But there is another task that is not forgotten for a minute.
That is the concern for the health of aimen.

explains the administrator of the pilot's medical service, the out-

Abstract: A n=ber of trends in cybernetics concern the problem of modeling
of complex objects. r1he authors show that in spite of the differences in
initial assumptions, all of. these trends can be reduced to the creation of
very complex objects, the qualit~y of which is determined by the extent to which
the~y can "learn" rapidly: i.e., the extent to vhich they can "construct an
internal model of an external situation." Modelo studied includ(! the Ciabor

Abstract: The paper presents a numerical integration of the system of
kinetic equations which describe the reaction of ignition and combustion of
hydrogen, for various initial states and kinetic models of the system (in-
troduction of additives, change in the initial level of concentration oil
active centers, addition of water vapor). These calculations are done to
determine the sensitivity of the kinetic model to the effect of changes
in small initial concentrations of active,centers, and to define the part
played by nonisothermality of the combustion process. A comparison is made
with experimental data on ignition delays.

Abstract: Cooperative phenomena were found and studied. In glasses activated
with Yb-Tb, Yb-Eu. It is shown that there are at least two mechanisms for
anti-Stokes excitation of the Tbl~ and. Eu3+ ions: fast (cooperative sensi-
tized luminescence) and slow (combinational excitation). Some quantitative
parameters of the cooperative processes were determined.. A study was made
of the functional dependence of the efficiency of the cooperative processes
on excitation power and energy, glass structure and composition, temperature,
and activator concentration ratio. It Is shown that disorder of the structure
of the glasses does not prevent the occurrence in them of cumulative processes
such as cooDerative sensitization and combinational excitation, the efficiency
of the cumulative processes in the glasses being commensu ble vith the effi-
ciency of two-photon absorption with the participation of the virtual level.

mariensite are observable. The potential wear resistance of
plates with the martensitic structure of steel is higher than that

Abstract: The relation between the detonation rate D and the charge
diameter d was determined for mi-xtures of pol7disperse hexogen poi.:-
der with a mean Darticle size of -r-.,, 0.1 mm and paraffin wax added'in
amounts of 10 28% with reference to.the mixture in the form of a
gasoline solution. On evaporation of the gasoline, the mixtures
were Dressed into tablets. The concentration and dispersity of
hexogen was the same in every~mixturo, while the porosity decreased
and the density increased with an increasing paraffin wax content.
With an increasing paraffin content, D increased. The D(d) curves
for mixtures with 10, 20, and 2LV%, paraffin showed a lower D plateau
from which D increased abruptly to a higher plateau at a certain
value of d that decreased with increasing degrees of filling with
paraffin. At 28% of Doraffin, the lower plateau was missing; D rose

directly to the 2nd -plateau. The~presence of two plateaus and the
abrupt increase in D, which amounted to 350 - 500 m/sec, can be ex-
plained by assuming that the initial surface reaction (lower plateau)
wassupplemented by a homogeneous reaction of the thermal e.,mlosion
type that took place within the volume of hexogen grains. The
surface of hexogen in mixtures was varied by using hexogen with a
grain size from 0.001 to 0.35 mm, while the degree of filling with
:paraffin was kODt constant at 2011o., With an increasing grain size,
entrance into the ist horizontal section (lower plateau) of the D(d)
curve took Dlace more slowly and the value of d at which the abrupt
transfer to the 2nd ulal-eau occurred became greater. For the mixture
U
with hexogen particles of.the grain size,0.001 mm, bhe lower plateau
was absent and the limiting.value of D (upper plateau) was reached
directly, evidently because the highly disperse explosive burned
rapidly. For the mixture with a hexogen grain size of 0.35 mm,
transfer to a higher plateau was not yet observed at d = 40 mm, the

and a transfer from it to a higher D level. Similarrelations were

hexogen-trotyl mixtures having the same density, but,a hexogen grain
size of.0.1 and 0.85 mm, respectively, while the trotyl grain size
was the same (0.1 mm) in bot:.~ cases, the D(d) curve for the mixture
with the larger hexogen grain size showed an abruDt increase to a

means of physico-chemical methods. It has been shown that the amount of
chemically bound phosphorus increases with increasing temperature of phos-
phorylation up to the maximum of W weight-%. At the same time it depends
on the pyrolysis temperature of the carbon fiber used in phosphorylation. By
means of chemical analyses and potentiometric titration it has been established
that the phosphorylated fibers obtained are monobasic ion exchange resins
with eychange capacity of UP to 3 mg-eq/g. The IR spectra and chemical
studies showed that along with the phosphorylation process there occurs
an addition of chlorine to the carbon fiber. The roentgenograms show that

L only in the second members of the limitations: i. e.,,problems with limi
-tations of the form Ax = b - v. It will be understood henceforth that all
plans considered are optimum for the new problem. The components of the
vector v are called discrepancies of plan x relative to problem L; the
V= z1vil is called the total discrepancy. It is readily seen that a plan
with v = 0 is optir-um- for the initial problem. Solution of problem L with

x to plan xI with v- vl= 6> 0 accomplished by means of some subalgorithm.
,At present the only known estimates for the number of iterations needed
,for attaining a plan [with] v= 0 are exponentially dependent on m. and n.
For a certain class of problems (the most important of which is a
transport problem) there axe no estimates of another kind. Let the problem
L be absolutely integral, and all the bi be whole numbers (then all ref-
erence plans are whole-number plans). Under these conditions it may be
assu d that iteration of the method of reducing discrepancies for L with
.respect to a whole-number plan gives a whole-number plan agains i. e.,the
total discrepancy decreases.. on each iteration by a whole number not less
than unity. Hence it follows that starting with a whole-number plan X0
with total discrepancy vo, VO iterations are sufficient for solving problem
L. In the general case, vo can be bounded from abo Ive only as Zbi, which
corresponds to a zero initial plan. -When solving problems by the method of

For a certain class of problems (the most important of which is the trans-

absolutely integer problem and all bi are integers (then all reference plans

iteration of the method of reduction of discrepancies for L according to the

decreases in each iteration by a whole number not less than 1. Ile see from

iterations are sufficient to sovle problem L. In the general case, vo can be

Heristem of Crepis capillaris Roots"
Riga, Izvestlya Akademii Nauk Latviyskoy SSR, No 7P 1973, PP 37-41
Abstracti Crepis capillaris seedlings were irradiated at 10+15, 10+3_5 and
10+55 rad with 1, 2, 3, 4, and 5 hour intervals between the fractions of fast
neutrons. The number of chromosome abberations beganlo decrease beginning
with the 2-hour interial between the fractions. The Offset of fractionation
varied with the total dose used. It was manifested after total doses of
25 and 45 raa but absent after a total dose of 65 rad. The number of two-hit
abbeiations was slight (about 10% of the one-hit.aberrations and chromatid
breaks) and independent of fractionation. The presence of such inhibitors of
protein and nucleic acid synthesis as chlorampb;nicoll 5- fluorouracil, 2,4-
-dinitrophenol, and aurwitin did not blocktlie effect of fractionation, suggesting
that.the latter was due to neutralization by endogenous protective systems
of the autagenic arA toxic substances produced in the seedlings by the fast
neutrons.

"The Physiological Mechanism of the Action of Dipyroxime"
Kiev, Fiziologichniy Zhurnal, Vol 19, No 3,.May/Jun.73, pp 310-314
Abstract: Therapeutic administration of dipyroxime to rats poisoned with
the insecticides DDVP (0,0-dimethyl-2,2-dichlorGvinyl phosphate) and
chlorophos resulted in a partial reactivation of cholinesterase in the
brain, spinal cord, and striated muscles, as shown by~histochemical data.
Cytophotometric studies showed that the reactivation of cholinesternse
under the effect of dipyroxime in the brain of animals poisoned with
DDVO was most pronounced in the caudate nucleus - putamen complex. Elec-
tromyographic investigation indicated,a beneficial effect of dipyroxime
on the transmission of impulses in nerve-muscle synapses. The results of
the study of the physiological action of dipyroxime substantiated the
conclusion arrived at in earlier work that this drug is effective in the
treatment of poisonings with DDVP and chlorophos (cf. Kagan et al,
Farmakol. i Toksikol., 3, 359, 1971).

ORIENTEDLY ON NEGATIVELY CHARGED.REGIONS:OF THE SURFACE AND RANDOtALY ON
THOSE CHARGED POSITIVELY. THE METHOD HAS.BEEN APPLIED TO THE STUDY OF
--TRIGLYCINE SULPHATE. LIF, AND NACL CRYSTALS. IT~HAS BEEN FOUND THAT
