reaction 11 14(n,p) and the dose due to absorption of ?--radiation
are calculated. For the purpose of determining the bioloeizal
dose the amount of the tissue dose must be multiplied by the
coefficient of the relative biological efficiency (accoriing
to the nature of the radiation). According to the quthors'
opinion, 5 is the most suitable value to select. for this
coefficient. From the maxirmlm values of the biological doses
correeponding to the depth of the tissue, the relative vilues
of the biological harmfulness per flux unit of neutrons -)f

TITLE: The Reflection by Paraffin and Water of Neutrons With Dif~~-r_-n'

ABSMACT: In the course of the solution of the problem of the biological
effect of neutrons it is of great importance to know such
quantities as characterize the reflection of neutrons of
different energies by a tissue. Besides, the dependence of' t-,
reflection coefficient on the geometrical conditions of the
beam must be known. The authors therefore carried out measure-
ments of the amount and the angular dependence of neutron
reflection by a tissue-like substance within a wide energy
interval. In these experiments the ratio between the flux cf
neutrons of all energies coming from the medium and the
flux of the neutrons to be investigated was determined. It 4a_-,
thus necessary to find out what portion of the total numbcr
inciding neutrons is absorbed in the substance. The authors
Card 1/4 employed two methods for measuring reflection: The first

In the transition of thermal neutrons to thermal deuteron. K~lh
an energy of B,3veral ev, the maximum shifts abruptly fi-om
to 2-5 cm. Thi3 may be due to the fact that maximtun Ftb~, r;t.-n
probably takes place in a depth of the order of one tran!'p,
length of the range of the inciding neutron. Also th(
comparatively 3low shifting of the maximum into the inturi r ,f*
the paraffin w:-th an energy increaLic to 5 Mev may be explainel
by the weak dependence of the scattering oross section in this
energy interval. The diagram mentioned indicatea a tenlenc~-
towards increaning on the part of the ratio between absorption
in the maximum and absorption on the surface. The velocity uf
absorption denuity decrease decreased with an increase of the
energy of the inciding neutrons. There are 1 figure and

TITLE. Diffusion separation of a gas mixture in the presence of dissociation
SOURCE: AN SSSR. Doklady-*, v. 156, no. 6, 1.964, i3i.6-i3iq
TOPIC TAGS: diffusion gas sepE-ration, gas diGGOCiatiOn, gas boundary 18'Yer,
diffusion coefficient, gas temlerature gradient, hydromechanics
ABSTRACT. The gas composition in the mixture of dissociating gases differs in
the boundary Wer from that in the outer flux, if there is a temperature gradient
at the surface. The separation is caused by differences in the diffusion coeffi-
cients of different components. This phenomenon was discussed in an earlier paper
(Izv. AN GSSR, Mekh I --nhinost,-.. #5, 117 (1963)). The present work deals with
the effect of various factors, cuch as the degree of dissociation of the gas In
the outer flux

concentration of the other (inext) gas, and the ratio of diffusion coefficients
of atoms and molecules of the dissociating gas. The assumptions are made in
computations, that the rate of the chemical reaction A2z==22A is zero In the
boundary layer, and is infinitely high at the body surface, and that thermal
diffusion inside the boundary layer is absent. The following cases are considered,.

PURPOSE- This book is intended for metallurgists and welding engineers.
COVERACIZ: This is a collection of scientific papers dealing with the formation
of hot cracks in ingots, castings, and welded products. 3ore papers arr- con-
c-erried mainly w1th the natuiv or mechanism of the D,--enomenon; others examine
the Pffect of factors such as steelmsking procedure. Sufficient evidence is
presented to identify some of the causes of hot cracks. Various means of
investigating and preventing the phenomenon are described. A number of rief-
Prences, bolbSoviet and non-Soviet, accompany the papers. F")r fuxther co-verage
see the Table of Contents.

Dobrokhotov, N. N. Effect of 3teelmakinir Tv--chnique on (;~xallty of r.Ven-
hearth Ste-el
The author makes the fol-lrywing recommendations; At the end of the run
the basicity of the sLag, i.e., the ratio of CaO to S102 , should be
within the limits of 2.~ and 3.09 and the fluidity of the slag, a8
tested by v1scosimeter, should amount to some 30-60 =. Preliminary
deoxidation of the steel in the furnace by means of blast-furnace
fprrojilicon should not be carried out. If ferrochrome and ferro-
manguwse have been added, tntf time for holding the reat should be
determined by the formula z . I-5Q , min., where q = the veigbt
of ferroaLloys added (in kg), and P the output of the furmace
It',24 hr). In the production of carbon and lav-~alloy steel,
alloying and deoxidation should be carr-ied out In the teeming ladl
Goverwaent standards (GOST Y,0-50 and 5521-50) for rimmed steel
should be revised so as to specify a manganese content of 0.30-0-50
percent instead of the present 0.31-0.6o percent.

The author points out that hot cracks are one of the main causes of
rejection of velded and cast products. To solve the problem he
suggests Intensive study of the hot strength of metals, using several
differP-Di'. --aches: 1) Investigation of deformations caused by
