A simple quantitative method (based on INIcCarty's method) of measuring the ribo-
nuclease (RNase) activity in urine and blood is presented. The RNase activity was
examined in the blood and urine of patients suffering from chronic granulocytic
leukaemia, myclablastic leukaeYnia, lymphatic leukaemia, granulocytopenia, Hodg-
kin's disease, and in cases of infectious disease with an increased leucocytosis. The
RNase activity in the urine is increased in chronic granulocytic lcukacmia, while the
RNasc activity in the blood serum remains unchanged. In other diseases, in spite of
an increased or decreased leucocytosis, no essential changes in the RNasc activity in
the urine and blood serum were observed, which indicates that there is no close
relationship between the number of leucocytes in the peripheral blood and the
RNase activity in the 24-hour sample of urine.

comparison, there were 20 patients with lymphatic leukemia (11.)
.and 20 patients with myeloblastic leukemia (ml). The control
?consisted of 150 healthy people. The serum and urinary activity
was determined by the orcinal method, and later by the spectro- i
,photometric method. AcPase activity was determined by the Bessey ;
-method; creatine and serum nonprotein nitrogen were assayed by.-.,,i
the methods of Jeffrey and Rappaport, respectively. The
results were 1) Agreement of nucleolytic activity of serum
and urine with well-known properties of ribonuclease was shown.
2) Serum RNase activity was markedly elevated both in the
serum and in the urine of the patients. 3) AcFase activity was
comparable in both groups. 4) There was a marked correlation
between levels of serum and urinary RNase aLtiVity in the
ipatients. In cgl, less pronounced correlation indicated die-
orders in the excretion of RNase. 5) RNase clearance values in
cgl were shown to be neither dependent upon serum RNase
Iactivity nor related to the levels of leukocytosis. 6) A
distinct correlation between leukocytes and RNase activity,
_described by the following formula, was shown,
I where Y is the-Berum RNase "aEtivity in ug/a 'ana: X is cgl
-leukocyte count in thousands. Maximal RNase activity occurred
in range of low leukocytosis (around 3000) and highest
leukocytosis (100,7-300,000). Lowest values of RHase occurred

00-- -- M -0.,
X&7i4-_AR03_1249'
in range of leukocytoBis from 10,000-300,000. Experiments in-
Idicate that there is A.state of equilibrium between RNase I
activity and level of leukocytosis in cgl. As a result, high
levels of leukocytosis are accompanied by high RNase activity;~-!
The occasional drop in the leukocyte level is explained by a
negative feedback relationship. This hypothesis supports the
Yiew that leukocytes are a source of serum Mae. The authors

Magnetometer Based on the Ha I Effect and Working on
Alternating Current
PERIODICAL: Pribory i teklinika eksperimenta, 1960, Nr 2,
pp 107-110 (USSR)
ABSTRACTs A description is given of an instrument based on the
Hall effect (Ref 1) in n-type germanium. The instrument
has been designed for% a) measurement of the absolute
magnitude of magnetic fields between 0.03 and 17000 Oe
to an accuracy of + 1% + 0.5 0-9 b) relative
measurement of the topoiraphy of magnetic fields to an
accuracy of I to 390" and c) measurement of fluctuations
in the magnetic field at a given point, The probe is
excited by an alternating current (4 mA) at 2500 CPS.
The Hall emf is amplified by a narrow-band amplifier
having an overall amplification coefficient of 1.5 x 106.
The instrument was calibrated with the aid of a nuclear
Card 1/2 magnetometer. There are I figure and 17 references,

377 OH groups. Synthetized products had molecular weights from
1200 to 1400 and these were determined-by the cryoscopic method?
in phenol. Use of these varnishes on copper conductors has given
resistance to 5000 volts potential, thermal stability up to,1550C,
and good resistance to wear. Especially good results were obtained
with the varnish based on polyethylene terephthalate modified with
ethylene glycol, glycerolt pentaerythrite. There are 6 figurest I

TEXTz The effect of the medium on the degree of crystallization of polyviroil
acetate was studied and a new possibility of producing highly crystalline
polyvinyl alcohol was shown. The lowest ketones were found to be the best
media for crystallization of polyvinyl alcohol. Vinyl acetate was poly-
merized in methyl-ethyl ketone (10) in the presence of azoisobutyric acid I
dinitrile at 600C. By s&ponifying polyvinyl acetate in methanol, polyvinyl,
alcohol with a charaoteristic viscosity of 32 was obtained in the presence i
of 4% caustic soda at 400C. The chain transferp intensified by,the m9diump
was found to accelerate crystallization. Much higher valuea of the chain
transfer constant were found for the lowest ketones than for,other aub-
mole-!
stances. The polymers developing under these conditions hay a.lover

ABSTRACT: The paper is a continuation of previous work (Refs.5 and 6).
Earlier papers by other workers (Refs.1-4) have dealt with
the creep of prismatic bars; in the present paper the stress
relaxation in a bent prismatic bar undergoing unsteady creep
is discussed. The cross-section of the bar possesses two
perpendicular symmetry axes, and stresses in longitudinal
planes are neglected in comparison with stresses in the cross-
section. It is assumed that the non-linear relation between
stress and creep strain is characterised by the function:
F(a) = cca + PaM (M >0)
(1.8)
where a and m are constants. This equation has been
Card 1/2

SOV/179-59-1-10/36
Relaxation Problems in Bending of a Prismatic Bar
found to fit the experimental results over a wide stress
range for many materials, e.g. concrete and wood. On the
basis of the above assumptions , a non-linear integral equat-
ion is obtained and a method of solving it is described. The
solution is then applied to the problem of the relaxation of
bending moment in a bar with rectangular cross-section.
Approximate evaluation in the case of a particular concrete
beam 20 x 30 cm in cross-section shows that relaxation of
bending moment depends markedly on the value of 0 in
Eq.(1.8). There are 1 figure, 1 table and 6 Soviet references.

of the homogeneous boundary problem for the 2nd order differential*
operators with generally no definite quadratic form. A family of
special automorphisms of the boundary is introduced and its depend-
ence on the relation be.tween the appearance of the bounded region
and a numerical parameter is investigated. A uniqu-eness theorem is
proved which is Theorem 8b. Let D be an arbitrary "allowed" region
and the relation T).(T')/2:rf given by

be irrational. Then the solution of (4) identically equal to zero
will be unique in the class of partly discontinuous functions. The
region is "allowed" if an arbitrary straight line intersects its
boundary at not more than two points and 59'). Necessary*condi-
tions are given for the existence of associated functions of the
first homogeneous boundary problem for the equation of vibrating
string, and sufficient conditions are derived for the value of the
numerical parameter ?,to belong to the spectrum of the basic opera-

and (4) out of discrete solutions by integrating them along a spe-

some class of differential solutions for the basic operator. This
condition also assures the continuity of the spectrum of the opera-
tor in some intervalo and the method is given for constructing
smooth "allowed" regions which differ as little as necessary from
the circle and in which the above conditions are fulfilled. Then it
is shown that there exists a complete system of functions which
assumes zero value on the surface of the n-dimensional hyperephere
and which satisfy inside that sphere, an ultra-hyperbolic equation
containing one numerical parameter. The equation is
