Eight series of vaccine from the brain of white mice infected with different strains
of the virus of encephaliti aponica were prepared, concentration of virus sus-
pension being the same Insil of the series, corresponding to their content of 5110
brain tissue. Experiments on the immunological characteristics of the vaccine
were carried out on white mice 2 weeks old. It was stated that the formalin vaccine,
precipitated with aluminium -hydroxide (I.R. -index of resistance - 105) was the
most effective and ether vaccine (I.R. - 16) the last effective. The addition of 0.2576
phenol to the formalin vaccine did not decrease its antigenic properties (I.R. - 44).
The immunity of vaccinated mice was proportionate to the amount of antigen intro-
duced. Further experiments, cvrried out on volunteers (immunization with vaccine
containing 57o of infected brain tinsue of mice 0. Ile for malln and 0. 2576 phenol)
showed an Increase In - 1rus-neut.-alizing antibodies In the majority of those vaccin-
ated after a repeated of vaccine. The highest concentration of antibodies
was observed in the blood of subjects vaccinated for the third time within two
months of the Irdtial one. References 13. Kaulen - Moscow

'Me m r the epidemiology, prophylaxis and diagnosis of
the tick spring-surnmer encephalitis (Russian text)
SOVETSK.,NIED. 1956, 11 (23-29)
The problem of tick encephalitis occupies an important place in numerous areas of
the Soviet Union, particularly due to the increased incidence of the disease. In
1935, 336 new popu lation cent res were added to the list of mass outbreaks. A high
Incidence of spontaneous virus infection of the tick Nodes persuicatus (up to 40%)
was. found in certain areas, where about 870/a of the population became infected.
In certain regions a neuroinfection which is related to spring-summer encephalitis
has been observed. This is the so-called two-wave meningo- encephalitis or milk-
fever. The agent is a neurotropic virus carried by the tick Nodes ricinus and 1.
persulcatus, however, in certain cases the infection is milk-borne originating
from goats. A vaccine has been prepared from chick embryos which shows specific
antigenicity and immunogenic properties agaiLlSt tick encephalitis.

Orig Pab: Sov. meditsina, 1956,4NO 3P 13-19
Abstract: The contemporary concepts of pollonyelitis epidemiology are
briefly stated. The problem of epidemic seasons is mentionedp
of virus localization in the hunway, organism, of the path_+f
transmission and the dependence of general and adult morbidity
of.the density of the population and means of c-inication.
The characteristic properties of poliomyelitis virus are stated,
and the significance of different serologic types. The essen-
tial principles of phrophylaxis and, particularly, the problem
of preparing a killed fornalinized vaccine.. are stated. The
importance of a correct ind'6peedy laboratory poliomyelitis diag-
nosis utilizing tissue cultures is emphasized.

G sidae may, to some extent, be responsible fof- the transmission of
spring-sinmer encephalitis; thia family of mites in a natural focus of
infection, can be a reservoir of the disease. In Kemerovskaya Oblast',
the natural infectiousness of Lalaptidae u. Heamogwmsidae, gathered
from the nests of rodents and shrews during the non.-epidr--mic season
(July-August, 1954), vas demonstrated. It is concluded that the virus
of mite-born encephalitis had been preserved alive in these mites for
no less than 1 month.

Interference was determined after 2-3 days and was judged positive in
the abs'ence.of cytopstbic activity and on the basis of plaque formations
of~the indicators in the test cultures and their presence in control3.
Interference of varying degree was seen after 72 hours for all tbree
viruses,
-1t was found that JEV can be reproducibly titrated and
identified, according to interference in tissue cultures upon introducing
-the blocking viruses.after 96 hours, Highest sensitivity.was found in . Ii
cultures-of chicken embryo cells and VM, for under these conditions the
interference activity titers (1/10 of activity in'controls) were close
to tbose,of the virus obtained in tests witb mice. This interference
was seen only with live virus. From tissue cultures Infected witb,tbe
JEV interferon was isolated, which alone also roduced Interference,,
resulting in reduction of plaque formation by I

ABSTRACT: The allergenic properties of antigens forming at various
stages,of virus propagation in the brain tissue of experimentally
infected white mice.were studied,in 97 guinea pigs by the metbod of
anapbylaxis and desensitization,-applying a 5 fluid brain vaccine
against spring-summer tick-borne encephalitis prepared 2 days and 4days
after infection. For sensitization, 0-3 ml were given subcutaneously
and the anapbylactic injection was 'given intravenously after 28-33 days.
Desensitization was given every 2 bours until complete arrest of the
reaction. The desensitizers were suspensions of normal brain, 2 or 4

-Says' vaccine, and.culture-derived formalin inactivated vaccine against
.the above disease. Sensitization of the guinea pigs with a suspension
of.healtby.mouse brain tissue caused only weak anapb-ylactic reaction
jpon subsequent introduction of the some suspension. Sensitization with
-vaccine from brain of-mice without clinical signs of the disease caused
anapbylactic reaction; so did vaccine from sick mice. The
anapbyle.dtic reaction in guines.pigs sensitized with the 2-day vaccine

ABSTRACT; The interaction between three strains of tick-borne encepha-
litis virus (a highly virulent Oriental strain, the less virulent TR-21
strain, and an attenuated variant of TR-21) with Ehrlich ascites and
Crocker cancer cells from nice was studied in vitro and in vivo. No
parallelism was noted between the interaction of viruses and cancer
cells in vivo &nd in Vitro. In primary cultures of both types of can:.'
cer calls, encephalitis viruses retained their infectiousness and pro

'duced significant changes In the cancer calls. In the culture of
Crocker sarcoma calls, the calls lost some of their ability to grow on
the surface and to cause the formation of tumors when live animals were
inoculated. In the culture of Ehrlich ascites carcinoma cells, a de-
crease in metabolic activity was observed after the interaction of
dancer calls with the viruses. The interaction between the various
viral strains and cancer calls after subcutaneous and intraperitoneal-
Inoculation caused active multiplication of the virus and affected the
proliferative capacity of the infected cello. The Oriental strain of
encephalitis virus multiplied most rapidly, and was able to penetrate
.brain tisnue after inoculation into an ascites carcinoma. Under iden-
tical conditionag the less usurovirulent TR-21 strain did not spread
.beyond the tumor into which it was injected# Orig, art, has: I figure

ABSTRACTj The authors report on a find of tungsten minerals made in
the North-Western section of the Ukrainian crystalline
shield in 1956. The wolframite encountered for the first
time was in foliated pieces with black, nontransparent
grains. Some pieces had, however, dark red and red color,
ranged from nor-transparent to almost transparent. In some
instances, the wolframite was found in combination with the
quartz, and in separate instances in combination with the
arsenopyrite. The majority of grains were within 0.6 - 0.1
mm, some reached a size of 2 - 3 mm. The chemical examinat-
ions made by B. V. Myrs'ka table 1), and the x-ray examinat-
ions made by A. 0. Karpenko (table 2), confirmed the
materials as being basically wol.framite, combined with an
Card 1/2 almost equal number of ferberite and huebnerite molecules.

ABSTRACT: The author describes a new dump car designed by him and con-
structed at the TsEMM Kanskugoll trest (The TSEMM of the Kansk-
ugol I Trust) to replace existing dump cars. The dump car con-
sists of a hood, bottom platform, unloading mechanism and the
carriages. The hood has three transverse End two lengthwise
edges welded into one stable spatial structure. The unloading
mechanism has the following basic parts: 36 kw electric motor,
the main reducer, two auxiliary reducers, and three 'Lifting
screws. The capacity of the hood is from 33 to 35 cubic meters.
Unloading takes 70 seconds and may be Pk~rformed by one man.

ABSTRACT: Dump cars applied at present in open pits have essential
drawbacks: high dead weight and dependence of the un-
loading time upon climatic conditions and the physical
properties of the load. The author of the present article
has designed a new type of dump car which unloads not by
tilting, but by shifting the walls of the vehicle over
the bottom, as is hown in Figure 1 and 2. Its main parts
are: 1) the walls; 2) the bed; 3) the unloading me-
chanism, and 4) the undercarraige. The technical cha-
racteristics of the new type are as follows: weight -
22 to 23 tons;,the weight of load - 60 tons; the capacity
of body - 33 to 35 cu m; height - 2,860 mm; width -
3,600 mm; lengths (between the axes of automatic couplings)
- 9,480 mm; unloading time - 70 sec which can be reduced
to 20 or 30 sec by applying more powerful electric motors
Card 1/2 and a lower gcar ratio. The unloading mechanism shifts

the walla of the dump car over its bed at a rate of 0-03
M/sec. The walls, shifting over the bed, form a slit up
to 3,000 mm. wide, through which the load is pushed out.
Such an experimental car was manufactured in the central
electro-mechanical shops of the trust "Kanskugoll". It
was tested in the Irsha-Borodino open pit in 1957. Tests
were carried out under all temperatures. The unloading
performance was satisfactory, and took less time thin that
of conventional dump cars. The frozen rock is scraped
from the bottom of the car by the back wall of the body.
There are 3 photos, 2 figures and 1 table.

ABSTRACT: Splitting of EPR linese/d Cr3+ in ZnW04 by an external
electric field has been detected, An investigation has been made of
the angular dependence of splitting (dependence of splitting value on
orientation of external magnetic and electric fields with respect to
crystallorgraphic axes). A Hwiiltonian spin is set up describing the
inter'action between the system and the external electric field. Corree,
tions to the transition frequencies have been found. The theoretical
resalts satisfactorily describe the experimental angular dependences
of the splitting, The corresponding Hamiltonian spin constants have

Abstract : The relative cross sections of the (n,p) reactions on
isotopes of Zr, Cd, Ti, and Sr, and Ca were measured by
analysis of the curves of nuclear decay vs. reaction
products. From the data obtained and from the analysis of
the data by Pauli and Clarke '(Referat Zhur Fizikaj 1955J.
8684) on the cross sections of the (n,p) reactions on iso-
topes of Mg, Si, 8, Zn, and Ge, the author draws the fol-
lowing conclusion: (1) The cross sections of the (n,p)

reactions on nuclei with several isotopes are reduced
substantially with increasing weight of the isotopes.
This reduction is greater for the lighter nuclei. (2)
In light nuclei, an increase in the atomic weight by
two units reduces the cross section to one quarter
(Ca, Si, S, Zn) or to 1116 (Mg, Ti), vhile in heavier
onee the reduction is to one half (Sr, Zi, Cd, Ge).
(3) The results obtained apparently contradict the
statistical theory and possibly are evidence of the
retention of the shall structure even at high excita-
tion energies.

ABSTRACT: First of all the authors give some information on relevant preli-
minary papers. It is the aim of the paper under review to demon-
strate unambiguously that the 5.5-hours palladium activity belongs
to a certain isotope or isomer of the palladium. For this purpose,
experiments were carried out with regard to the radischemical se-
parati*n of isomers in the mixture of the radioactive isotopes of
palladium which are produced at the reactions Cd(n,a) and Pd(n,2r
The method of the chemical separation of the nuolear iaomera is
based on the Szilard-Chalmera phenomenon. When working on the me-
thoda for the apparation of the palladium isomers, the authors of
the paper under review tried reagents: dimethyl glyoxime, aceto-
xime, salicylic aldoxime and a-nitrose-p-naphtel. The beat results
were obtained with salicylic aldoxime. Salioylic aldoxime is suited
for the separation of the nuclear isomers of palladium.

During a period of 4 hours, 400 9 of cadmium nitrate were exposed
to radiation of a current of neutrons of 14 119V (^0107 neutrons/am 21

of the radioactive palladium isotopes produ ilia' t the reactions

ly connected with Pd (T-22 min.).

The oross sections of the reactions are computed from the data
of these charts, and they are compiled in a further chart.

cross section of the reaction Cdl
2(n,a) Pdl09 amounts to (1-35

cadmium nitrate were exposed to radiation by electrons, dissolved
