"Petrographic Investigation of Rough Globular Elements in ShKhl5 Steel"
Moscow, Stalt, No 2, Feb 71, pp 166-168
Abstract: The coarse, globular nonmetallic elements found in ShKhl5 steel
and determined by X-ray analysis to be largely of magnesian spinels, marked-
ly debase the quality of the steel and adversely affect its characteristics,
often leading to the discard of individual alloys. This article describes
the method used by the authors to eetermine the phase state of these ele
ments by the petrographic method, in which sections of the steel were
examined under the microscope after metallographic study. The elements
are from 100 to 150 microns in size, and were discovered in the ShKh'5SG
alloy as well as in the ShKhl_5, both manufactured by the "Dneprospetestal"'
plant. rhey can be classified in three groups, differiug in shape, re-
flective capability, and behavior under polarized light. Most of them had
the chemical composition of 2CaO-SiO . The petrographic examinatiork yield-
ing results which agreed closely witg the X-ray study, showed that the
elements correspond in phase and structure to slag, from which they prob-
ably originate.

I'Study of the Trajectories of Particles in tavale Nozzles"
Mekhanika Zhidkosti i Gaza, No S, 1971, pp 136-143.
Abstract: A method is presented for calculating the trajectories and para-
meters of liquid or solid particles during flow of two phase streams through
Lavale nozzles, allowing the number of particles precipitating onto the wall
of the nozzle to be determined and the momentum loss phenomena related to
this to be evaluated. A method is suggested.allowing the known gas parameters
to be used to produce an approximate deteimination of the trajectories ar'd
parameters of particles in the sub- and supersonic portions of the nozzles
and to determine the number of particles striking the nozzle wall, to deter-
mine approximately the density, velocity and temperatur& of particles, to
establish certain qualitative specifics of flow, in particular,the formation
near the nozzle walls of closed and open zones in which particles of a given
size are absent. One defect of the method is that when calculatinp the move-
ment of particles, changes in gas parameters caused by delay of particles are
not considered.

Abstract: In 1967 a method was developed by the author by means of which
i twas porsible to calculate the subsonic, transonic and tiupersonic flow
regions in a Laval nozzle, this method being based an a solution of the
inverse problem of nozzle theory, in the solution of which is determined
a family of flow lines corresponding to a given distribution of velocities
at the axis. In the present article, this method is used.to conduct a
parametric investigation of flow in the subsonLc and transonic regions by
varying the parameters characterizing the distribution ofv4Aocities along
the axis and selecting them in such a manner that the shape of some flow-
line would fully or partly correspond to the given nozzLe contour. The
effect of the adiabatic index and the effect of the shape of the transonic
region upon flow in the supersonic region of the noza-e is conald-Lred. A
conh)arison.is made of the numerical solution with the resu)As al tpecial
experiments in which was investigated the flow in nozzles valculated
according to the above-mentioned method.

Abstract: This brief communication offers the rt-sults of a study of
the action of a constant magnetic field of 5000 oersteds
on the reaction of the transhemization of oxyhemoglobin (Hb02)
in mice after 24 hours. The reactions and the processing of the
experimental data were performed by the known method of Blyumen-
felld and Charnyy, in 1�50, and Blyumenfelld in 1-957. The ex--eri-
mental Ea of this re-oction is the same as the E., in the reduclion
reaction of h-bO?, which makes investigation of 15he transhemization
reaction convenient for estimating the functional state of the
hemoglobin. The authors find that the value of E.,, they obtained
for mice is the same as the value Of Ea for the Ht02 in dogs and

"The Variation in K, Na, and Ca Ion Concentrations in the Ascitic Fluid of
Animals With Tumors Following the Action of a Constant Magnetic Field"
Moscow, Izvestiya Akademii Nauk SSSR, Seriya Biologicheskaya, No 2, Mar/Apr 72,
pp 268-272
Abstract: White mice were inoculated with tumor cells from the ascitic form of
Sarcoma 37 and then, 1-13 days after inoculation, were exposed to a constant
magnetic field of 5.103 oersteds for periods of 3-5 clays. At various time
intervals after cessation of exposure to the field, thd.- mice were examined for
changes in the concentrations of potassium, sodium, and calcium ions in the
extracellular ascitic fluid. Statistically reliable increases of up to 50%
were observed in the concentration of potassium ions. Given the same duration
of exposure to the magnetic field, greater increases occurred during the early
stages of development of the tumor and when measurements,were taken immediately
following exposure to the field. In fact, by the 6th day after cessation of
exposure ~:m increase in potassium ions could no longer be observed. The con-
centrations of sodium and calcium ions did not vary.

Abstraett A study was made of the effect of a constant magnetic field on the
state of the blood syztem and the free radical content In the blood of aice.
The constant magnetic field intensity was 5,000 oersteds for exposure times
of 4, 24 and 72 hours. After exposure to a constant magnetic field, the number
of erythrocytes, reticulocytes and leukocytes in the blood of mice inertases,
the hemoglobin content increases, the erythrocyte pmLuction per cubic milli-
motor of blood per day increaseep and the free . radical content increases.
A change in the qualitative composition of the erythrocytes expressed In an
increase in the number of cells of increased stability is observed. A

"Effect of an Electrostatic Field on the Survival Time of White Noapurebred
Hice After X-Irradiation"
Moscow, Izvestiya Akademii Nauk SSR, Seriya Biologicheakaya, No 3, 1973,
pp 435-438
Abstract: Nonpurebred mice were subjected to whole-body irradiation at 500 r
and then placed in a specially designed chamber where they were exposed to an
electrostatic field of 1000 v/cm for 1 or 24 hours. More controls were alive
11 days after irradiation than experimental animals, but by day 30 the sur-
vival rate of the latter exposed to the electrostatic field for I And 24
hours was 27 and 36% higher, respectively. The higher initial mortality
is attributed to the early biochemical changes triggered by the electro-
static field. Subsequent intensification of the oxidation-reduction pro-
ceases prolonged the survival time of the more radioresistant animals.

"Changes in the Content of Free Radicals in Mouse Organs During Hypoxia and
Hyperoxiall
Moscow, Izvestiya Akademii Nauk SSSR, Seriya Biologicheskaya, No 1, 1970,
pp 93-99
Abstract: Experiments on nice showed that during hypero.-cia changes in free
radical.activity are the same in the liver, heart brain, lungs, and muscles.
Tha content of free radicals increases on the 2nd day, ilecreases on the 3rd
day, and increases markedly on the 4th day in all the organs. During hypoxia,
changes in the concentration of free radicals are also Lhe same tn lirer,
spleen, brain, and lungs. Free radical concentration increases on the first
day and after that decreases below control values. However, the rate of change
varies from organ to organ. For exampla,' in the lungs and spleen the free
radical level falls below controls on the 3rd day and continues to fall there-
after, whereas in the brain and liver this pattern is not observed until the
4th day. It was suggested that changes occurring in free radical activity
as a result of hypoxia and hyperoxin may be one of the:factors responsible
for the impairment of certain physiological systems and:metabolic processes
associated with these states.

Moscow, Izvestiya Akademii Nauk SSSR, Seriya Biologicbeskaya, Ito May/Jun
70, pp 463-467
Abstract: The effect of laser irradiation on the ultrastr.tcture of Harding-
Passy melanoma was studied. it was found that. the zones w"-iich bad not been
irradiated directly contained irreversible changges. Ylitoctiondria were mos-u
damaged, and their organization disrupted, whtoret.~s the myelin atructures,
nucleus and nucleoli, and virus-like forzkqtions showed. no
changes. A strong vacuolization in the cy-toplasm of the cells was noted.
Temperature changes in melanoma tisGue are proportional to the distance from
the center of laser action. All changes in me-lanom-a tissuE~s under the action
of lasers are explained on the basis of the thermomechanical effect.
