Abstracti . The Influenza epideraics which lasted from Decomb-,.~r 1968 to April
1969 in the USSR, afflicting 12.41% of the population, and from February to
April 1969 in Biagaria, afflicting 5.!~Z of the population, had several

both developed more gradually but las.*.ed longer than previous epidemics, and
the soverity of -the diseases was mild to moderate, so that no special dis-

virus A2 were i2olated in the USSR, or which 439 itere investigated, while
22.6 strains of the same virus were isolated a~.d Inver, tigated in BulGarla.

between the absolute moisture content in atmoipheric air and the

Translation: It is shown that the condition of attachment of the connrres-
sion shock to the sharp sweDtback leading edge of a body, determined on the
basis of flow analysis in the immediate vicinity of the leading edge -as flow
around a flat wedge, is necessary, but not Gufficient. Detachment of the
shock depends also on boundary conditions downstream frcm the edge, and nay
begin considerably sooner than on an equivalent wedge 4n the cross section.

Abstract: Cotton f:Lbers were kept in a rotating magnetic field of 400 to
.800.a/cm for 1 to 10 minutes, with relative.humidity ranging from 65 to
80%. In all cases,.th-is treatment enhanced the.tensile strength of the
Cotton fibers, with the maximum increase of 0.2-0.3 g observed after 3
minutes of exposure. Follow-up tests demonstrated that this improvement
Was.durable. Infrared spectroscopy of the fibers revealed shifts in
maximum absorption bands, and x-ray analysis..showed a greater degree of
polarization of the polymers (up 2-4%).after the treatment. The feasi-
bility of applying this method in industry is being investigated.

Abstract: An experimental study was performed of the chinge in micro-

titanium carbide uader the influence of neutron bombardment with integral
doses of 1.0-1019, 3.7-1019, 7.5-1019--and 1.5-1020thermal neutrons per

at about 50% and u;ith subsequent annealing in a vacuum of !0-~, mm h.g. at
100-1,000*C at intervals of 100'C for I hour. Metallographic studies
showed no change in mean grain size. Bombardment with the largest dose
caused an increase in specimen volume of 0.3-0,55o. Bcmba-rdment caused a
significant increase in resistance and lattice parameter. A regular shift
in diffraction peak;s toward lower angles with simultaneous decreases in
intensity was observed, as well as improvement in the degree of resolution
of the a doublet on the (333) line, Annealing at 100C.1iiereased the
lattice parameter, while annealing at,200-800*C decreased the lattice
parameter. The experimental data indicated that there are.two stages of
-recovery in annealing, at 350 and 600'OC. The~similarity of the mechanisms

Abstract: As hav been shown in earlier work by Lebedev et al., use of a
cutting instrument to the edge of which axial vibrations of ultrasonic fre-
quency are imparted reduces considerably mechanical deformation of tissues
that are being cat and the damage to these tissues. This is particularly
important as far as the tissues,of the brain are concerned. Furthermore, an
ultrasonic knife has an inherent hemostatic effect. An ultrasonic cutting
instrument has biaen developed the handle biwhich contains an electroacoustic
converter. The generator to which the instrument is connected has a maximum
power of 100 wt. The vibration frequericy'of~the instrument is controlled
automatically. At a working frequency of 22 kilocycles.+ 7.5%, the amplitude
of vibrations of the instrument with a weight not exceeding 110 g amounts up

to the generator. The ultrasonic knife will be particularly useful for pre-

the cortex. It can be fastened to the ma ipalator of a stereotaxic apparatus.
