"The Special States of a Cyclical Model of a Discrete Device"
Riga, Avtamatika i Vychislitelinaya Tekhnika, No 4, 1971, pp 1-5
Abstract: This article describes a cyclical model of a. finite automaton in
which a complex logic converter is used to substantially reduce the number
of delay elements -aeeded and to simplify:the,coding Df:internal states to
~T the maximum degree. The coding of i internal: states can be simplified because
of certain features of the model's transition tables which make it possible
to sinplify the equations which describe: the functioning of the model. The
model has u+2k4ln+2 feedback loops :(where, n, ~, and m are the number of input,
intermedi ate and output signals, ~respectively) ,but only one of them con-
taius a delay element. The model, as described in the~article, has numerous
memory:elements, but this is for the general:case: some or all of these can
be. eliminated-with synthesizing models of specific finite automata. Although
chronous-aukomAta, tM'results can easily be
the (tiscussion is. limited to asyn
extended to synchronous automata-'

latvian Academy of Sciences is a complex,of scientific institu-
tions which, as a rule, successfully combine basic research with
investigations for the specific needs:Lof different sectors of
the national economy. The most important line of research in
the Institute of-Physics is developmental work on a theory of
the hydrodynamics of incompressible media, which haa mado possi-
ble the creation of electromagnetic pumps forl'use in atormic re-
actors, special power plants, and in the:metallurgical industry.

MHD devices have been the basis for the realization of a funda-
mentally new scheme for.the industrial raproces~sing of mei, cury
which has been tested under operatin ~conditidxls in the Soviet
Union. Research on the interaction of radiation with matter has
made possible the creation of thormoluminescent dosimeters for
--the'.recording of nuclear radiation as: well as recoumendations
regarding the development of tic'al

the Institute of Economics has made possible the development of
an automated water resource control system as well:as the solu-
tion of problems involving the creation of an 'automated control
system at the Latvian Ministry of Health.. In the field of engi-
neering linguistics the institute of Language and Literature is
developing a system for automated processing of speech informa-
tion for purposes of creating a statistical model of Lettish,
The problems in constructing the material base of communist
society require a sharp increase in the effectiveness of scien-
tific research. There arenfive possible ways of accomplishing
this.
1. Organizational measures, This inethod requires no capital
investment and is very fruitful~ yet it in rec:eiving insufficient
attention. The tendency to work on minor,subjects~still exists
to some extent in all the institutes of the Academy. One of the
most important problemn of the Academy is toconcentrate its
forces and resources on the main scientific areas. Partioularly

serious attention should be,givon to.subjects directly related
~to the national economy. The. Institute of Pol-,mer Ylechalliics
has begun to take measures to increase the ef4foctivenoss of it:~
research and bias reorganized its structure, An
optimal subject plan needs to b9 developed, corresponding to
the social need for given studies:andito the capabilities of' the
institute. The Planned Production Division needs to imrove the
system of resource allocation-among the scienbific institutions
of the Academy. The question of incentives and wages for scien-
tific workers demands attention. Attention should be given to
organizational and technical-measures connected wit
-h the develop-
ment of applied problems and the creation of new processes,
materials,:machines, and systems. This is the weakest and most
difficult sector of the Academyls organizatio.nal Woxsk. The need
to cut down on the time it takes to go from theoretical research
through planning and testing to the creation Of now technology
and techniques roquiros the unification of all th6se stages under
a single administration. This.meana the croixtion ot acientific
assooiations which include institutes, planning and design bureaus,

and experimental enterprises.
2. Strengthening ties with production. There should be special
offices in the institutes to. find.in.a theory under development
everything that can be utilized in applied projects; to draw up
-he
and supervise the plans for these projects; ~to check on t
cooperation of laboratories,, design bureaus, workshops, and
experimental enterprises; to keep~in-touch with production onter-
prises and directive organs-, to gather information on actual re-
sults, make reports, etc. Almost;all design bureaus in the in-
stitutes are understaffed,' and their work and.the*coordination
of their activity with laboratories, workshopo-, and ezperimental
enterprises is poorly organized. Planning and design work in
the Academy is lagging and constitutes the bi$gest I~ottleneok
impeding the acceleration of developmental woiuk for the national
economy. The only way to overcome this is to attach to insti-
tutes relatively large plamiing-and-design or planning-and-
technological bureaus functioningon:a cost accounting basis,

accounting basis will result in businesslike.and effective forms
of collaboration between scientificAnstitutions and enterprises
and industry. Serious attention'should be given to the develop-
ment of.an experimental base for the
-scientific institutions
of the Academy.
3. Automation.. First steps in this direction are being taken
at all the institutes of the Academy. The Academy now has at
its disposal four computers and one data.proGessor as well as
skillod programming mathematicians and olectronic engineers.
Work has been begun on the.creation of an Academy-wide Scienti-
fic Data Processing Center.: The question of'tho creation of
'an Academy automated scientific data processing system is on the
agenda,
Enlarging the role of information subdivisions. The Academy
needs an information system functioning distinctly as an infor-
mation service. Most institutes already have.:info.-mation divi-
sions or groups, Information work-at.the InsUtute of Economics

is especially good. However, the ~infonraation system in the rest
of the institutes is not effeativeenough.
Raising the skills of staff scientists. Seminars and lec-
tures on the latest achievements in science-should be organized
at the Academy. The-personnel training division must take urgent
measures to increase foreign-langu go instructions
Finally, the consumers production,enterprises "- need to
e ject3 of
change their attitude towards the:developm ntal proJ
scientific institutions. For example$ in 1964 the .0hysics and
Power Engineering Institute got the idea of creating a gonemotor
LTranaliterated from the Rusaian7. In 1966 the Inntituto created
a pilot model of the machine, Zd,in 1967 the,genenotor was
accepted by the Riga Electrical Machine-Building Plant for intro-
duction into production. In 1969, a patent i,~Ls obtained for
the genemotor, and it is not being patented abroadl. Three years
have passed, but the invention.'still has not been introduced into

"Contact Mcroscopy in Reflected Light"
:Optiko Mekhanicheskaya Rromyshlennost'. No 12, 1972, pp 27-30.
Abstract: A method is described for contact microscopy in -reflected light.
Various methods of illumination of total biological preparates are studied
when this method is used. This,is essentially a new type of microscopy,
requiring the development of special apparatus and methods of preparation
of the objects to be studied, including.living biological specimens. In
many.eases, the method can be used as an independent, simple method of in-
vestigation of pathological-anatomical material. 1 The device allowing con-
tact microscopy in reflected light can be made by construction of a simple
addition to an ordinary microscope using a low-power iiicandescent bUlb as
the.light source. The method eliminates the need forl-Acrotones, material
freezing systems, reduces the need for reagents and eliminates the necessity
of a laboratory assistant.

Moscow, Nekhanika Zhidkosti i Gaza, No Ju I -Au% g70, pp 161-174
Abstract: The article deals with relaxation behind.shock waves
in air at velocities of B-12 Im/see., PrQfiles of the gas para-
meters behind the front are obtained. The:population densities
of radiant states of atoms and molecules are ccu%jutad. , The
spectral radiation distributiona of the relaxation zone are found,
In a number of spectrum intervals the radiation' intensity passes
through a maximum which is in excess of the equ IIlibrium level.
-A eonpari3on is made with oxporimontal data obtainod in shock
tubes. The radiant fluxes of heat from the relixai;~on zorra are
comouted, Estimates are made of the contribution orthis radA
tion to the radiation heating of blunts .bodies a hypersonic

Abstract: The results of recent research in the field of ionization relaxa-
tion is slin-nnarized and problems as yet unsolved are pointed,out. It is noted
that relaxation phenomena behind shock waves have been:.discussed in surveys
and monographs but that problems of ionization relaxation were not given suf-
ficiantly complete cQverage because the basic results In this field were ob-
tained only in recent years. These successes have resulted in intensive ex-
perimental. studies at large Mach numbers, and prooress i.n. the' theory of kinetics
in a low-temperature plasma. Probl of;ionization ktnetics in a plasma,
initial ionization mechanisms, the structure of the relaxation zone, and
radiation of the nonequilibrium, zone are! discussed in the survey. The table

It Is noted that there is not now any satisfactory theory for,the radiation

plexity of elementary processes in a molecular plasma. Tt is also pointed out
that studies have shm-in that the contribution.of nonequilibrium radiation to

may be differentfor-other planets.

Abstract: Numerous substitutes for nutrient materials also include

permeability of the blood-brain barrier and temporarily reduces protein

To deternine the poi-ne-ability, the animals we~,e deeapit~4ed 15 min later, and

Moscow, Gigiyena Truda i Professional'nyye.Zabolevan.iva, No 12, 1971, pp 22-25
Abstract: The effect of vertical vibration of rabbits on the vascular bed of
the liver was studied. Three rabbits were subjected to vibration of 50 Hz
with an mm amplitude of 1.3 mm for 120 days,.four rabbits, for 40 days, and
four rabbits served as controls. Histological studies showed that the total
area of the liver blood ve-qsels and capillaries increaqed by 26% and 58%
after 40 and 120 days of vibration, respectively. Art4-TiOlc8 were affected
more profoundly than capillaries in thi& re6pect in bolli cases. Their firea
increased by 34 and 70% after 40 and 120~days of vibration, respectively.
Number of capillaries and arterioles also,increased. -Interlobular veins,
main veins, and capillaries were~d:Llated:and:distended~with blood, and the
presence of perivascular infiltrations and hemorrhages:vas detected in all
experimental animals.

Moscow, Gigiyena i Sanitariya, NG 12, 1970, pp 98-100
Abstract. The dynamics of histologicalland histochemical shifts was traced
in the-gastric muscosa of white rats exp :osed to whole-body vertical, vibration
(frequency of 50 liz and amplitude of 0.8 mm).for up to:,180 days. Within 30
minutes of the start of vibration, the secretion of all varieties of epithe-
lial cells in the gastric muscosa increased. A large~quantity of Schiff-
positive substances appeared on the surface of the mucoba. Ilepsinogen
granules were found in the chief cells of the terminal ends of the fundic
glands. The changes intensified but then stabilized after the 10th day as
adaptation developed. But by the 60th day, the regenera'tivelca-pacity of
the.epithellm, of the gastric mucosa became. exhausted. The thickness of the
membrane decreased in places and the-number of secretory-. cellt diminished.
By the 90th day extensive degenerativelchanges were evident in the mucosa of
the..fundus ventriculi and attenuation of the mucusa. became general.
