ABSTRACT: ALthough the hysteresis loops obtained experlihentall7 in the
quasistatic alternating magnetization of tbin films in generol recall
theoretically obtained hysteresis loops, there is a main difference
between them, In a, theoretical hysteresis loop, the process of alter-
nating ma netization appears to be a bomogeneoug rotation of the magne-
tization freversible and irreversible), The process of quasistatic
alternating magnetization is not a homogeneous rotations and the appear
and and growth of domains plays a large role in it* By a study of the
Barkhausen effect and observation of the domain structure, the present
*article attempts to analyze the processes of the shift in boundaries
and the rotation of the magnetization and to evaluate their contributio:

to the obange in'tbe magnetic moment of a film* The tests were made on
films of 80NKhS alloy produced by vaporization of the metal In a vacuum,
The spraying time was 6 see. The thickness of the films was 2000-2500 j
and the diameter of the patch was 9 mmo Hysteresis loops obtained on
one of the films at a frequenc7 of 400 cycles, at different angles to
the axis of-weak magnetization, exhibit a well developed monoaxial
anisotropy* An osoillograpbio study was made of the Barkhau3en skips,
with alternating magnetization at different angles to the axis of week
magnetization, and with the application of a transverse field. It was
concluded that there are no significant regions of the film wbiob are
subject to alternating magnetization by a skipping type or rotation, A
figure shows the dependence of the contribution of the skips to the
total change in the magnetic moment of the film on the angle between
the alternating magnetization field and the axis of weak magnetization,
A second figura shows the dependence of the contribution of the skips
on the magnitude of the direct current field perpendicular to the alter.
nating magnetization field. The smallest of the skips observed bad a
duration of about Oo5 microseconds$ and the largest from-150-200 micro-
seconds. The dependence, obtained experimentally, of the irreversible
change in the momeiit of the film on the magnitude of the transverse
field differs strongly from the theoretical* OrIge art, has: 2 figurei

TITLE: Foundation Drainage in .0arth Dams
PERIODICAL: Gidrotekhnicheskoye stroitellstvo, 1959, Nr 7
pp 37-

ABSTRACT: The article deals with the initial work on the foun--
dation of a hydro-electric dam, which was constructed
in two stages in order to provide a temporary reser-
voir cofferdam prior to the icing-over of the river;
time did not allow for the lengthy and complex cons-
truction of a core in the first stage, and Fig 1 shows
how this difficulty was obviated by building the first
stage dam, which was 99 m high and faced by a loam
slope protection, extending 200m along the island dam.
A drainage system was installed in the base of the
downstream slope of the dam, which was to filter off
all the water from both the island dam and the river-
bed dam, as shown in Fig 2. Figures are given for
the rise in the amount of water discharged through
the drainage system in proportion to the rise in the
level of the reservoir. 111owever, 'this rise had '-.o be

being discharged from outlets 4 and 4a was workinr~-
some of the gravel loose; it was established that -:L-,,e
drainage flow in the island dam, travelin-, perpendi-
cular to the axis of the dam, had worn away a cavVI-y'
in the loam core (Fig 4). The eroded area was cle;-iBed
out and filled up with a sand/gravel mixture for a
L
distance of 25m along the dam. A brief account of
this repair process is given, which was only a tempo-
rary measure until the central loam core could be
constructed at the second stage of construction. Con-
clusions drawn from the breakdown in the filtration
system are enumerated at the end of the article, tl'ie
chief one being the necessity to avoid excessive pres-
sure during the winter months. There are 3 diaf.~-re_mc
and 1 graph.

Gomori's method was used for estimation of acid and aflaline phosphatascs (phos-
phomonoesterases) in normal rat tissues after single total irradiation (dows NO r.,
1000 r., 3000 r.), after total repeated irradiation (close 300 r.) and after irradiation
of the head only (dose 4500 r.). Thymus, spleen, bone marrow, intestine, scininal
vesicles, pancreas, brain, liver and kidneys were examined. It was found that after
general irradiation there is an increase in acid and alkaline phosphatase activity in
the spleen, thymus and duodenum. After a dose of 3000 r. there was increased alkal-
ine phosphatase activity in the liver. In other organs there was no change in phos-
phatase activity. After head irradiation there was a slight increase of alkaline phos-
phatase activity in the thymus, spleen and liver at the time of death of the animals
(6-8th day). These results indicate profound changes in the phosphorus metabolism
in the organs where X-rays cause destructive changes (cell necrosis).

of the heart. of chicken embryo. Even a lengthy stay
(11 hours) of the cu-Itare in Ringer solution (I), which
contained 110 /ml of DRA depolymerose (II) does not
lead to a change of the intensity of staining of nuclei
according to Fel6en. In incubation of explants in borate
or veronal b,,,.ffer., which contained II, a weakening of
the staining ability of nuclei was noted. The effect in-
creases with increase of II concentration and lengthening

of the inctibation pei-iod. By means of neutral red, it
was descovered that a buffer medii-aa irreversibly injures
the cells. In action of II on cUtures which were killed
by heating, hydrochloric acid, alcohol, or "suza" fiya-
tive, weakening of staining according to Felgen was noted
independently of whether the cells were in the buffer
solution or in I. Irradiated cultures (irradiation sour-
ce- radon) were placed for 3 hours into a buffer soiution
with II (experlmcntal Exoup) or witlilout enzyme (control).
A certain weaken-;ng of staining of nuclei in the e~~,jei-i-
ment was noted, i,~hich did not e-Ceed that in non-irradi-
ated cultures which were incubated in the buffer solution
with II. In inc-L-.bation with I, these differences between
the experiment and the control were absent. The authors
showed that the polymeric DNA in solution under influeice
of irradiation does not lose the ability to depoly-,aerize
under effect of II. The latter induces a weakening of

cells killed by irradiation and subjected to autolysis
of cultures. The authors feel that in irradiatioa, in
differentiation from other injuring agents, nucleoproteide
is isolated in which MM and protein are securely bound.
This bond is distvxbed only in autolysis. -- I.M. Shapiro
