Dear  Dr. Lenimar Nunes de Andrade,

I wish to take this opportunity to ask you if you could offer me an employment
in  the  area  of  symbolic/numeric  computations and/or their applications in
Applied/Pure Mathematics, Mechanics,  Hydrodynamics, Computational Physics  or
Engineering.   I  would  like  to  get  an  appointment  preferably related to
using/extending Mathematica, Maple or  Reduce system in business,  research or
educational purposes;  others  computer algebra systems,  for example,  Axiom,
Macsyma, Theorist, are of interest to me as well in this respect.

I would be immensely grateful to you for information about possible vacancies,
opening positions, any useful advice or for kind assistance.

I would be very grateful to you if you could find an opportunity to forward my
request to the Chairman of the Department (to the Personnel Director or to the
Hiring Committee) or,  if it is possible, to the colleagues  interested in CAS
and/or Computing.

Some information about me. My name is  Alexander Urintsev.  I am 47 years  old
and presently work as a Senior Research Associate at an International Research
Center of Nuclear  Physics, the Joint  Institute for Nuclear  Research (JINR),
situated in Dubna (Russia).  I am engaged in developing data-analysis  systems
and processing the experimental  High Energy Physics data  by means of various
statistical  and  numerical  programs  and  some  sorts  of computer graphics.
During three  last years  I extensively  used in  my daily  work the wonderful
graphical, numerical and symbolic capabilities of the Mathematica package  and
the Maple package as well.

But now I have rather bad perspectives  to continue my work in Russia, as  the
conditions for  scientific work  in the  field of  Computing or  other serious
professional  activity  in  the  area  of  fundamental or applied research are
degrading  permanently,  and  there  is  no  hope  that  the situation will be
improved in the nearest future.

I would be very grateful to you if you could find an opportunity to answer  me
if there  is a  possibility for  me to  work  at your University  on any basis
(contract, post-doc, etc.). It  would be very nice  for me to be  employed for
permanent work  (or for  several years)  to develop  new application areas for
Mathematica, Maple  or Reduce,  or carry  out research/business investigations
in  the  field  of  symbolic/numeric  computation,  Applied/Pure  Mathematics,
Mechanics,  Hydrodynamics  or  Physics  working  as  a  scientific programmer,
researcher or software engineer.  Also, I could work as a teacher of  Computer
Science, Mathematics,  Mechanics or  Hydrodynamics having  an ample experience
in  teaching  undergraduates  at  the  Rostov State University (Rostov-on-Don,
Russia).

Therefore I enclose here  some additional materials  pertaining to my request:
Resume,  List of Publications,  five letters of recommendation  and  copies of
scientific degrees.

I  would  like  to  inform  you  that  I  have  got  an  experience in Applied
Mathematics,  Mechanics  and  Computer  Science  during  24 years of work as a
researcher at several  research institutions.   My work is  connected with the
various problems of numerical and symbolic  analysis.  I received my Ph.D.  in
Mechanics of Fluids, Gas and Plasma in  1980.  During a long period of  time I
worked with problems  of hydrodynamic stability  and appearance of  turbulence
and  acquired  an  experience  in  solving  the  Navier-Stokes  equations   on
computers.   I  am  familiar  with  modern  software,  libraries of scientific
computer programs such as NAG Fortran Library, CERN Program Library, IBM  SSP,
Harwell Subroutine  Library and  with a  wide range  of computers.   Besides I
possess  the  11-years  experience  in  teaching  students  at the Mechanical-
Mathematical Department of  the Rostov State  University, where I  lectured on
Programming   in   Computer   Algebra   Systems,   Computational  and  Applied
Mathematics, Analytical Mechanics and Theoretical Hydrodynamics.

Earlier, during some 9 years, I had used quite actively and with some  success
the computer algebra  system REDUCE, based  on LISP, with  a research purposes
and  to  teach  students  of  the  University to Pure and Applied Mathematics,
Mechanics and Hydrodynamics.  As a result, I have published several scientific
papers concerning  the application  of symbolic  computations in magnetostatic
optics of charged particle.

The Institute,  where I  work, has  bought Mathematica  and Maple,  and I have
used since 1991 these systems: at  first I dealt with the Mathematica  Version
1.2 and  later with  Maple V  and the  Mathematica Version  2.0. My scientific
work supported  by  Mathematica and Maple  was a  great success  and now, as I
believe, I  am quite  experienced in  the Mathematica  and Maple  programming.
Particularly, thanks  to Mathematica  and Maple  I succeeded  in making a good
mathematical model of  the ununiform 3-dimensional  magnetic field inside  the
spectrometer with  a vertex  detector.   It was  created at  the JINR together
with the  Institute of  High Energy  Physics (Serpukhov)  to solve some urgent
and important problems  of Particle Physics.   Also, I would  like to  mention
that by  means of  Mathematica and  Maple I  has successfully investigated the
dynamics of the longitudinal motion  of charged particles in the  TRITRON type
accelerator.  The fulfilment of  these and other scientific tasks  resulted in
new Mathematica  packages pertaining  to Applied  Mathematics and Mathematical
Physics.  Apparently, these packages may happen to be of more significance  in
applications.  Mark Moline, the MathSource Administrator of Wolfram  Research,
helped me to install in the MathSource Collection at Wolfram Research these  7
packages (please see the List of Publication, ref. c38 - 44u).

As I hope, the  List of Publications (enclosed)  will allow you to  appreciate
my  experience  in  Applied/Computational  Mathematics  and programming in the
field of symbolic/numerical computation.

In conclusion of my letter I would  like to inform you that during 7  months I
am  a  member  of  MathGroup  and  a  member  of the electronic teleconference
sci.math.symbolic as well.   Besides, since  March 1992 I am  a member of  the
Reduce Forum. It allows me via electronic mail to maintain relations with  the
specialists in the field of symbolic computation over the world. It should  be
noticed  that  this  intercourse  with  developers of computer algebra systems
helped me to  improve essentially my  style and level  of programming in  this
area.

If you  should require  additional information  regarding my  work experience,
education or personal situation, I would be happy to provide it.

Dear  Sir,   I am very grateful  to you  for the trouble   you have taken to
consider my request.   I would appreciate any help.  Thank you for your time.

I look forward to your reply.

Sincerely,

    Alexander Urintsev, Ph.D.

P.S. Dear Sir, please acknowledge the receipt of my letter when you
     receive it.  The point is that for the last two weeks our electronic
     mail functions unsteadily, and this is why I would like to know:

     Have you received my message or not ?

   I have known Dr.  Alexander  Urintsev for about 9 years. I  was introduced
to him in Rostov-on-Don,  where I lived in  those days. In Rostov  we carried
out  a  joint  investigation:   me  and  Dr.  Alexander Urintsev  by means of
computer have simulated the solidification  process of molten steal.   It was
very important to obtain a sufficiently accurate solution of the problem  for
concrete values  of physical  constants and  sizes of  steal castings because
specialists in casting  assumed to use  the results of  our investigations in
practical work at  Rostselmash,  a big  plant situated  in Rostov-on-Don  and
producing many sorts of agricultural machines.

Mathematically the full problem of solidifying of molten steal is  formulated
as a complex system of  nonlinear partial differential equations in  one time
variable and  three space  variables under  relevant boundary  conditions. It
should be stressed that the  existence of the mobile boundary  between molten
steal and a growing hard part of the casting results in serious  mathematical
and calculating difficulties in solving the problem.  We have considered  the
process possessing of a rotatory symmetry.  I provided Dr. Urintsev with  the
relevant  equations  describing  the  studied  phenomenon and interpreted the
obtained numerical results on computer.

Being  a  high  level  specialist  in Computational Mathematics and Computing
Dr. Alexander  Urintsev proposed  a new  effective approach  to get numerical
solution  of  the  problem  based  both  on using spline-approximation of the
unknown functions and  solving Cauchy problem  for stiff systems  of ordinary
differential equations  by means  of the  new numerical  method published  by
Gear.   To solve  the problem  on computer  Dr. Alexander  Urintsev created a
large original computer code. The problem  was solved in a short time  period
and  the  results  of  the  computer  modelling  obtained  by  us  were quite
successful and very useful for the specialists in casting.

I  greatly  appreciate both  the  scientific activity  and  good personal and
professional  qualities  demonstrated  by  Dr.  Alexander Urintsev during the
work on  the given  scientific project.   I believe  that  Dr.  Urintsev is a
highly  qualified  specialist  in  the  field  of  Computational Mathematics,
Programming and Computing.   I would like to  recommend him for working  as a
scientific  programmer  at  computer   firms  producing  complex   scientific
software,  research   institutions  and   as  a   teacher  of   Computational
Mathematics and Computer Science at universities as well.

   I have known  Alexander Urintsev for  more than 20  years. In his  youth he
showed good mathematical abilities.   As a winner of regional  competitions on
mathematics and physics among  school-children, Alexander was accepted  to the
Mechanical-Mathematical  Department  of  the  Rostov  State  University by the
Rector's  order  without  entrance  examinations  before finishing a secondary
school. On graduating in 1969 from the University he continued his studies  as
a post-graduate at  the  Mechanical- Mathematical Department of the University
for two years.

He defended successfully  the thesis on  "Mechanics of Fluid,  Gas and Plasma"
under  the  title  "Appearance  of  Auto-oscillation  Modes  of Viscous Liquid
Motion  at  the  Loss  of  Stability  in  Laminar  Flows"  at  the Problems of
Mechanics Institute of the USSR Academy of Sciences.

>From 1971 till 1990 Dr. Urintsev worked at the Research Institute of Mechanics
and Applied  Mathematics of  the Rostov  State University:  first as  a junior
research associate, then from 1975  as a senior research associate.  In autumn
1990 he was invited  to work at the  International Research Center of  Nuclear
Physics, the Joint Institute for  Nuclear Research situated in Dubna  (Russia,
Moscow Region).

For 24  years Dr.  Urintsev has  been working  as a  researcher. Carrying  out
active investigations in applied mathematics  and mechanics of solids, he  has
been recognized as  a qualified specialist  and initiative scientist.   He has
published about  40 scientific  papers.   Repeatedly, the  Directorate of  the
Research Institute of Mechanics and Applied Mathematics rewarded Dr.  Urintsev
with premiums for successful work.

Dr.  Urintsev has got the First Prize for a series of published papers on  the
nonlinear  theory  of  hydrodynamic  stability  at  the  Research Institute of
Mechanics and  Applied Mathematics.   He has  obtained and  published  several
important  results  on  the  appearance  of  auto-oscillation modes of flow in
pipes,  canals  and  boundary  layers;  he  has  investigated  the  parametric
excitation of cell  convection in vibrating  cavities filled with  liquid. The
problem of the appearance of finite  amplitude waves on the surface of  liquid
flowing down because of gravity, has been solved by  Dr. Urintsev  rigorously.
The problem of the liquid film  flowing is known to be closely  connected with
the design of heat exchangers, and the investigations on vibration  convection
are strongly motivated by the  development of space technology of  monocrystal
growth under the conditions of reduced gravitation on board the spaceship.

The package  of specialized  computer codes  developed by  Dr. Urintsev allows
one to  solve various  problems of  the nonlinear  stability of  laminar flows
within short time periods. He  has actively participated in investigations  of
the  convection  in  salt  (sea)  water  carried  out at the Rostov University
according to the request  of the Applied Physics  Institute of the Academy  of
Sciences. The  results obtained  and the  programs created  were given  to the
Applied Physics  Institute, approved  by specialists  and used  afterwards for
practical work.

Dr.   Urintsev has  worked during  10 months  at the  Department of  Numerical
Methods  in  Mechanics  of  Solids  of  the  Problems  of  Mechanics Institute
(Moscow,  the  Academy  of  Sciences),  where  he has actively participated in
numerical  simulation  of  nonlinear  hydrodynamics  processes.   The relevant
scientific results were presented by Dr. Urintsev as a report under the  title
"Numerical  Solution  of  Hydrodynamic  Stability  Problems"  (381  pages) and
published by the Institute.   The FORTRAN package developed  by Dr.   Urintsev
during  this  time  was  applied  by  the  contributors  of  the Laboratory of
Numerical Simulation in Hydrodynamics at the Institute.

Dr.   Urintsev  made  numerous  reports  at  the  Seminar  on the Mathematical
Problems of Hydrodynamics (under Professor  V.I. Yudovich), at the Seminar  on
the Mechanics of Solids (under  Academician I.I. Vorovich) held at  the Rostov
State University, at the meetings  of the Rostov Mathematical Society,  at the
11-th Winter Conference on Theoretical Physics  in Kirov, at the 1-st and  the
2-nd  All-Union  Conferences   on  Modern  Problems   of  Heat   Gravitational
Convection, at the 4-th and  5-th All-Union Seminars on the  Numerical Methods
in Mechanics of Viscous Liquids, at the 18-th Siberian Thermophysical  Seminar
"Wall Turbulence", at the Research  Seminar on Aeromechanics and Gas  Dynamics
at  the  Institute  of  Mechanics  of  the  Moscow  State  University   (under
Academician  G.I. Petrov),  repeatedly   at  the  University  Conferences   on
Nonlinear Problems of Hydrodynamic Stability  Theory held by the Institute  of
Mechanics of the  Moscow State University.   Dr.  Urintsev's  papers are  well
known to the specialists in  the theory of hydrodynamic stability,  working at
the Siberian Division of the Academy of Sciences of Russia:  at the  Institute
of  Thermophysics,  at  the  Institute  of  Hydrodynamics, at the Institute of
Theoretical an Applied Mechanics, at the Applied Physics Institute and at  the
Problems of Mechanics Institute of  the Academy of Sciences, at  the Institute
of  Mechanics  of   the  Moscow  State   University  and  at   other  research
organizations  that  work  on  the  problems  of appearance and development of
turbulence and also on the problems of applied mathematics and mechanics.

A series of papers  of Dr. Urintsev published  together with  Dr. G.S. Markman
are devoted to the theory of appearance of autowave processes and  dissipative
structures which is a new  domain of physics studying the  nonlinear phenomena
of the nonequilibrium thermodynamics of solid bodies.

In 1986  - 1990  according to  a contract  between the  Research Institute  of
Mechanics  and  Applied  Mathematics  of  the  Rostov State University and the
Institute for Nuclear Research of the USSR Academy of Sciences,  Dr.  Urintsev
together with Dr. Alexander Samoylov  carried out the joint investigations  in
the field  of magnetic  optics of  charged particle  beams using  the computer
algebra system REDUCE.  The  relevant scientific results were reported by  Dr.
Urintsev  at   the  5-th   All-Union  Seminar   on  Program   of  Experimental
Investigations at the Meson Factory  of the Institute for Nuclear  Research of
the Academy of Sciences (Zvenigorod, 1987), at the 11-th All-Union Meeting  on
Charged Particle Accelerators  (Dubna, 1988), at  the Workshop on  Application
of Computer Algebra  Systems in Applied  Mathematics and Mathematical  Physics
(Dubna, 1989) and  at the IV  International Conference on  Computer Algebra in
Physical Research (Dubna, 1990).

At the  Rostov State  University  Dr. Urintsev successfully  supervised the  6
months  probation  of  Leonid  F.   Muratov,  the  researcher from the Pacific
Oceanologic  Institute  of  Far  Eastern  Research  Center  of  the Academy of
Sciences.   The  result  of  the  joint  investigations  was a paper published
afterwards  in  proceedings  of  "A  Symposium  On  Marine  Science in Western
Pacific: The Indo-Pacific Convergence" (Townsville, Australia, 1986).

In 1988 the scientific rank  "Senior Research Associate" was conferred on  Dr.
Urintsev  by  the Supreme  Certifying  Commission  at the Council of Ministers
of the USSR.

Dr. Urintsev is a  teacher with a great  experience. He has been  lecturing at
the Mechanical-Mathematical Department of  the Rostov State University  during
11  years  by  combining  lectures  with  research  working  as  an  Associate
Professor at  the Computational  Mathematics Chair  and also  at the  Chair of
Functions and Functional Analysis Theory.  From 1987 till 1990, as the  leader
of the initiative Group on  the Automation of the Analytical Calculations  and
the leader of the  seminar with the same  name,  Dr. Urintsev  carried out the
work on  the installation,  popularization and  teaching of  the users  of the
Institute of Mechanics and Applied Mathematics new software, computer  algebra
systems to make extremely complicated symbolic calculations on a computer.

>From 1984 till 1990  Dr.  Urintsev developed  and tested the software  for the
mainframe  computer  ES-1055M  (compatible  with  IBM  370  VM)  gained by the
Institute.   The high  qualification in  modern programming  tools and  modern
numerical  methods  allows   him  to  make   a  fundamental  contribution   in
acquirement, installation  and mastering  of the  new perspective  programming
systems and libraries of scientific and applied programs.

I would  like to  stress the   following personal  qualities of  Dr. Urintsev:
he  appreciates  both  his  own  working  time   and the working time of other
persons, strives  to   fulfil   the   entrusted job   in time   and with  high
quality, he is able to  support good  professional and  human relations   with
his colleagues, his subordinates and with management.

Summing up  the above  said, I  positively estimate  the research and teaching
activity of Dr. Alexander Urintsev at the Rostov State University.

I consider that  the high professional  level of  Dr.  Alexander Urintsev  and
his good  personal and  professional qualities  allow me  to recommend him for
working at any  research or computer  center, university, college  and also in
firm producing software.

   I have known Dr.  Alexander Urintsev  for a large period of time (about  20
years).  During  11  years  working  as  a  senior  research  associate at the
Research Institute of  Mechanics and Applied  Mathematics of the  Rostov State
University he successfully combined research with teaching at the  Mechanical-
Mathematical Department of the  University where I have  the honour to be  the
Dean.

During these years  Dr.  Urintsev  worked  as  an Associate Professor  at  the
Computational Mathematics Chair and at  the Chair of Functions and  Functional
Analysis Theory of the  Mechanical-Mathematical Department of the  University.
He lectured special courses in the field of computational mathematics such  as
"Solving  boundary  value  problem  on  computer",  led  seminars,  classes on
calculation  methods,   probability  theory   and  mathematical    statistics,
programming  in  computer  algebra  systems  for  students  of the Mechanical-
Mathematical  Department,  Applied   Mathematics  Department,  Economics   and
Philosophy Department  at the  Rostov State  University, supervised  students'
practice  at  the  University  Computing  Center  and graduates' practice.  In
fact,  he  annually  supervised  and  reviewed  diploma thesis of the students
specialized  at  the  Computational  Mathematics  Chair and at the Theoretical
Hydroaerodynamics Chair.  This pedagogical activity took 240 hours per year.

In addition,  Dr. Urintsev  lectured on  analytical geometry  at the  Regional
Refreshment Courses  for technical  college teachers.   For a  long period  of
time he took part in the activity of the editorial board of the journal  "News
of Northern Caucasus  Research Center of  Higher School" (Rostov-on-Don)  as a
reviewer of the papers in the field of applied mathematics and hydrodynamics.

Dr.  Urintsev  is  a  highly  qualified  specialist  in  developing  and using
numerical  and  symbolic  algorithms  and   programs,  as  well  as   computer
applications for solving problems of applied mathematics and mechanics.

Dr.   Urintsev  is  the  author  (or  a  coauthor)  of  about  40   scientific
publications.  He  pays a lot  of time and  energy to create  the high quality
computer programs, applies such programming  languages as FORTRAN 77, C,  Lisp
and also computer algebra,  libraries of scientific subroutines  (CERN Program
Library,  IBM  SSP,  NAG  FORTRAN  Library,  CPC  Program  Library),  computer
graphics in the scientific and applied researches.

Dr.  Urintsev is a persuaded  supporter and a skilful popularizer of  wide use
of such  computer algebra  systems as  Mathematica, Maple  and REDUCE both for
research and teaching of mathematics, mechanics and physics at Higher  School.
In 1988 the leadership of the Department asked him to lecture the term  course
under  the  title   "Programming  in  REDUCE   System"  because  of   possible
application  prospects  of  similar  computer  systems  possessing  artificial
intellect  traits.   The  lectures  were  prepared  at  high  level  and  were
accompanied by a great quantity of well selected examples.

Dr. Urintsev deserves respect and  prestige at the University as  a researcher
and teacher. The  colleagues have not  forgotten him, though  he has not  been
working for  several years  there being  invited to  work at the International
Research Center of Nuclear Physics,  the Joint Institute for Nuclear Research,
situated in Dubna (Moscow Region).

In conclusion, I would  like to recommend Dr.  Urintsev as a highly  qualified
specialist  and  teacher  for  work  at  the  universities, colleges, research
institutes, computing centers and software firms.

   I  have  known  Dr.   Alexander  Urintsev,  a senior research associate of
Particle Physics Laboratory at the Joint Institute for Nuclear Research,  for
three years. We have carried out joint scientific investigations.

>From  1991  to  1992  Dr.   Alexander  Urintsev  cooperated with me and other
members of the group  lead by me  on a project of the  high-current cyclotron
installation  of  the  TRITRON  type.  In  theoretical  plan  we considered a
possibility to apply such kind of accelerators to get the high-current  beams
of deutrons with energies sufficient  for the purposes of the  MINGEN project
aiming at creating a powerful neutron source.

When working  on the  project as  a scientific  programmer and researcher Dr.
Urintsev carried out symbolic  and numerical calculations using  the computer
algebra system  Mathematica,  FORTRAN 77 and  a series of scientific programs
>from CERN Program Library:   starting from formulae he successfully  realized
the mathematical model of the dynamics of the longitudinal motion of  charged
particle in the TRITRON type accelerator.

In studying various aspects of this problem he has shown the independence  in
realization of the part of scientific project entrusted to him,  demonstrated
deep  knowledge  of  mathematics,  numerical  and symbolic algorithms, tricky
methods  of  programming,  skilfully  used  splendid analytical and graphical
capabilities of  the  Mathematica system  to provide considerable  success in
work of the group on the given project.

That is why I greatly appreciate the scientific activities of  Dr.  Alexander
Urintsev in our collaboration and believe  that he is able to solve  involved
scientific problems connected with  a qualified application of  Computational
Mathematics  and  advanced  computer  systems  in the fundamental and applied
research.

I  believe  that  Dr.  Urintsev  may  be  recommended  for  work  at research
institutes,  scientific  centers,  laboratories  and  also in firms producing
sophisticated, applied and system's software.

   In this  letter I  would like  to recommend  Dr. Alexander  Urintsev as  a
highly qualified scientist.  I have known Alexander Urintsev during 28  years
since  1964.   From  1975  till  1982  I  had  a  pleasure to carry out joint
investigations  with  him.   We  have  published  9  joint  papers.  The most
significant of them are as follows:

G.S.  Markman,  A.L.  Urintsev,  About   the  Influence  of  High   Frequency
Vibrations  on  the  Appearance  of  Secondary  Convection Modes. - Izvestiya
Akademii  Nauk  SSSR  (News  of  the  USSR  Academy  of  Sciences), Mekhanika
zhidkosti  i  gaza  (Fluid  and  Gas  Mechanics),  1976, No. 2, pp. 90-96 (in
Russian).

G.S.  Markman,  A.L.  Urintsev,  About  the  Appearance  of  Finite Amplitude
Convection in Vibrating Fluid Layer Heating from Above. - Izvestiya  Akademii
Nauk SSSR (News of the USSR Academy of Sciences), Mekhanika zhidkosti i  gaza
(Fluid and Gas Mechanics), 1978, No. 1, pp. 27-35 (in Russian).

G.S.  Markman,  A.L.  Urintsev,  On  the  Theory of Dissipative Structures in
Turing-Prigogine Model.  - Biofizika (Biophysics),  Moscow, 1980, vol.   XXV,
No. 1, pp. 149-152 (in Russian).

During this  whole timespan   Dr.  Urintsev kept  high creative  activity and
demonstrated high competence in mathematical physics, excellent knowledge  of
numerical methods and high professional level of programming.

I  would  like  also  to  mention  his  ability  to cooperate in planning and
realization  of  scientific  projects,  including  the  creation  of original
computer codes of rather large extent.  He creates programs that function  in
such operating environments  as VAX/VMS, VM/CMS,  MS-DOS. He is  an expert in
such  programming  languages  as  FORTRAN  77,  C, Lisp, widely uses computer
graphics, such scientific subroutine  libraries as CERN Program  Library, NAG
FORTRAN Library, CPC Program  Library, IBM SSP and  a lot of others.   During
recent years he  has mastered the  computer system TEX  to prepare scientific
papers.

All these habits successfully allow him to create his own effective  computer
codes for different applications.   Such problems as hydrodynamic  stability,
convection, self-organization in  nonlinear dynamical systems,  appearance of
solitons,  calculation  of  motion  of  charged  particles  in transportation
systems, analysis and  projecting of nonlinear  magnetic optics systems,  are
investigated in his articles.  The relevant mathematical content  consists of
analytical and  numerical investigation  of nonlinear  differential equations
describing the researched phenomena.

Dr.  Urintsev uses successfully computer algebra systems such as  Mathematica
and REDUCE whose wide application is very perspective.  He studied the  Maple
package. A great erudition  permits him to work  effectively at any stage  of
research  including  the  mathematical   formulation  of  the  problem,   its
investigation  by  means  of  computer  and  final  analysis.  The scientific
results obtained by  Dr.  Urintsev are regularly published and  well-known to
the specialists.  He is  the author  of some 40  scientific  papers, many  of
which published in magazines of the Academy of Sciences and later  translated
into English.

Dr. Urintsev is quite experienced in  teaching. During 11 years he worked  as
an Associate Professor at the  Chair of Computational Mathematics and  at the
Chair  of  Functions  and  Functional  Analysis  Theory  of  the  Mechanical-
Mathematical  Department  of  the  Rostov  State  University.  He lectured on
programming, numerical methods,  probability theory,  supervised  the diploma
thesis papers and research work of graduates.

I would like to  mention that  Dr.  Urintsev is not only  a recognized expert
in his field  but he is also  a charming and reliable person  for  colleagues
and students.   As a  participant of  the collaboration  he is  known for his
ample working capacity, thoroughness  and persistence in developing  programs
and research projects.

I  believe  that  Dr.  Urintsev  is  an  excellent  specialist to work at any
research  center  or  firm  in  the  field  of  applied research and computer
systems,  besides,  he  is  a  highly  qualified  lecturer  and  teacher   at
university or college.

Subject:      A little answer
To:           "Dr. Urintsev " <URINTSEV@SE.JINR.DUBNA.SU>

Dear Dr. Urintsev,

       A received your long message last Saturday in the morning.
       I can't help you but I will forward your message to many other
people that work in better and greater universities here in Brazil. My
university is small; I think you wouldn't have interesting work to do
here in Joao Pessoa anyway.
       Last year I heard something about this: "Some universities in
Rio de Janeiro (more than 8 millions inhabitants) and in Sao Paulo
(more than 12 millions inhabitants) are interested in russian researchers."
I am not sure, but I heard that some russians are working in Rio de Janeiro
receiving 2000 dollars (???) a month. Our medium salary is about 1000 dollars.
       We have a Bitnet discussion list called SBM-L (e-mail: SBM-L @ UFRJ)
where we can contact almost all brazilian mathematicians. I sent your message
to SBM-L. Many people in Rio de Janeiro and Sao Paulo will read it next
week.
       We can live peacefully and easyly in Brazil. But we have too many and
too big problems. We have an inflation rate of 30 % a month. Some of the
best Brazilian researchers are going to live in USA and Western Europe.

       Congratulations for your Curriculum Vitae.
       Sincerely,

           Lenimar Nunes

P. S. I am sorry for my poor English.

Dear Prof. Lenimar Nunes,

Please excuse me for some delay in communication: I was away from my office
for several days (was in Moscow).

It was a great pleasure to receive a good, detailed letter from you.

Thanks a lot for your kind assistance !

Thank you for the undestandig situation of mine.  Also I wish to say that
I never have too many friends, and I would like to have a friend in Brazil.

Now I am hoping to receive letters from people in Brazil interested in my
experience.   One email message I have just received from Dr. Ronaldo Pena,
the Dean of Engineering of the Federal University of Minas Gerais.

Thank you very much for your kind help.

Hoping to hear from you soon. By the way: your English is superb !

With best wishes.
