TO ALL SCIENTISTS CONCERNED WITH SCIENCE AND TECHNOLOGY IN ARGENTINA
--------------------------------------------------------------------------------
Buenos Aires, June 4, 1990
Dear Colleague:
I would like to draw your attention to the plight of science in Argentina
and to ask for your urgent cooperation to save it from destruction.
As you may know Argentina is in the midst of a profound economic crisis.
As a consequence of this there has been a severe reduction in the governmental
budget. Unless special attention is paid to science we believe that meager
salaries combined with lack of funding will lead to the shut down of our
laboratories before there is any improvement in the economic situation.
The following example provides a glimpse of our economic situation: a
scientist holding the highest available position receives a monthly salary of
US$ 300 (United States dollars three hundred). On the other end of the scale a
junior scientist starting his/her career is paid a salary of about US$ 100.
These sums are far lower than those required for subsistence-level feeding and
education for an average family.
If you are willing to help us, please write a letter in your own words
or use the attached letter as a model and send it via air mail to
Sr. Presidente de la Republica Argentina
Dr. Carlos Saul Menem
Casa de Gobierno, Balcarce 50,
1064 Buenos Aires, ARGENTINA
To expand the chain please send ten copies of this letter to your friends.

MODEL LETTER
Sr. Presidente de la Republica Argentina
Dr. Carlos Saul Menem
Casa de Gobierno, Balcarce 50
1064 Buenos Aires, ARGENTINA
Dear Mr. President,
I am writing you to call your attention to the present situation of
scientific and technological research in Argentina.
Argentine scientists will not be able to endure for a long time the
present situation in which the lack of funds to support research is
combined with the incredibly low salaries paid to them.
Such situation will soon lead to a sharp increase in the exodus, which
has already started, of qualified people and hence to the irreversible damage
to your national scientific and technological research system whose quality
is recognized and respected by the international scientific community. This
would be a tragedy for Argentina's cultural and technological development
which would require years to repair.
With all due respect, Mr. President, I urge you to take actions to reverse
this sad situation. This may help to change the negative image that the
international community has about this aspect of your administration.
Sincerely yours
(Signature, name and academic position)

Estimados todos:
Esta es la primera vez que me dirijo a todos ustedes por medio de la red.
Creo que la situacion descripta mas arriba, conocida por todos nosotros, lo
justifica.
Hoy por la tarde recibi copia de estos textos del laboratorio en Argentina
del cual provengo y hacia el cual aun planeo regresar, este es el Instituto de
Quimica y Fisicoquimica Biologicas (IQUIFIB), Facultad de Farmacia y Bioquimica,
Universidad de Buenos Aires, cuyo director es el Dr. Alejandro C. Paladini.
Tengo entendido que los esfuerzos tendientes a revertir este estado de
cosas, en el medio local, son frustrantemente inoperantes. De este modo,
se trata de que la presion externa pueda ser mas efectiva.
Les agradezco a todos desde ya toda la difusion que pudieran darle
a esta iniciativa.

Alo, all. I'm looking for a small bit of code to help me calculate X,Y coordinates of a Z coordinate. What I'm trying to do is draw 3-D images with points at (X,Y,Z), but because I am only using Pascal for this, I need a way to compute the real X,Y coordinate on the screen where a dot at X,Y,Z should be placed. If you have any suggestions, or know of a book that discusses this, please send your comments to: IB35 @UNTVAX or IB35@VAXB.ACS.UNT.EDU Thanks a bunch. - Adam

I am looking for a good mathematical package which supports 3-d graphics. I particular I need a package which supports 3-d point plotting well. Most packages seem to have a good support for 3-d surface plots but not so good for 3-d point plots. If you know of any such package, pl. let me know. I don't usually read this newsgroup, so I would appreciate it if you can send me email at sushil@pixel.cps.msu.edu about this. Thanks, Sushil

I am looking for those images appear in some of the classical image processing text books. Any formats will be fine since one format can be converted to another, in most cases. 8 bit B/W or 24 bit color would be perfect. Can anyone send me an info. on some of the FTP sites that may have archives on these images? Or please respond to this article. My email addresses are: thssdhk@iitmax.iit.edu dhk@iris.iit.edu dk@garfield.bsd.uchicago.edu Any of addresses above will do. Thanks in advance.

Any experiences with 2D graphics pkgs for the PC? Something that
supports inputs as described in GKS...with support for more than just
request mode. The system would continuously outputing graphics while
simultaneously checking for kybd/mouse input; it wouldn't be
sufficient to block for input. Conceptually, this is what the system
would support:
mouse input --------------------------------------\
\
keyboard input --------------------------------------/========= process
/ Input,
graphics requests (from somewhere, maybe RS-232) --/ or Update

I hate to post ignorant questions but here goes it.
Recently I have been involved with the task of calculating
a thickness distribution on faceted (SP) 3-D data. To determine the
thicknesses required I pick a predefined point in 3-space near the model.
Then from that point I start shooting rays radialy outward. So, my question
is to all you raytracers... Are there available techniques for raytracing
faceted data. Also, this data will be used in radiation calculations where a
high degree of accuracy is desired. ANY information would be greatly
appreciated.
Thanks in advance

Hi,
I have been working on an alternative GUI system for plain DOS,Turbo BGI and
TP 5-6. I would like to support most of the GIU section of WIN3/MAC without
the GDI and other bitlevel graphics work. I expect to use ONLY the borland
BGI that is standard along with some SVGA BGI drivers posted recently.
My problem involves the methodology and logic of repainting exposed and
destroyed regions of windows. Initially I began with saving a bitmap of the
underlying regions of popped-up windows. It seemed to work fine and gave me
the least problems. That was before I decided that I wanted random access
windows (not just stacked). Also, using TP 6.0, 384KB EMS and DOS 3.3 left
me with only about 150 KB or so for background bitmaps.
What I wanted to do was find the most efficient way of updating window regions
that are destroyed or exposed without having each window procedure to implement
it's own methods.
I have looked at several GUI packages: WNDX,MENUET,ZINC,and a shareware toolkit
posted to comp.binaries.ibm.pc. The three commercial packages were underspec.
They were LARGE and the windows were either inconsistent with WIN3/MAC or they
were slow and cumbersome. These packages required MetaWindows - a third party
GDI library. BGI does NOT allow virtual windows written to RAM and does only
but the basic functions that a GUI would need. I have to use it.
So, without using MS Windows 3.0 SDK. How can I get some pointers or code to
demonstrate the updating of hidden windows,exposed regions and destroyed
regions?
I enclose a post I made to comp.lang.pascal a while ago including some p-code
that I was thinking off. Also, how does WIN3 handle the updating of destroyed
and exposed window regions?
----------------------------------------------------------------------------
I am still working on my simple user interface library for TP 5 & 6. I have
built most of the messaging system, window management and data structures -
bitmaps, ICONS etc.. In order to allow flexiblity for custom repainting of
exposed windows I have decided not to simply 'GetImage the underlying screen
background but to send messages to each window when its contents are over-
written. The window procedure then has the oppurtunity to 'GetImage the portion
of his window that is about to be overwritten. Later on, when the window
system discovers that a previously hidden region is about to be exposed, it
sends an EXPOSE message to the window with the region as the parameter. The
window can then 'PutImage the previously saved bitmap without having to get
the input focus (bring it's window to the top).
Since this procedure is very common for most windows, the base window class
will have defined procedures to handle the DESTROY/EXPOSE messages in case
the window or it's derivatives decide not to handle the messages. Right now,
I have a rough idea of the kind of data structures I am looking for:
RECT = Record
left,top,right,bottom :integer;
end;
RegPtr = ^REGION;
REGION = Record
rc :RECT;
next :RegPtr;
end;
I will need a function say, InvalidateRegion:
procedure InvalidateRegion(var rgn :REGION) {
wnd:=First(WindowList); {sorted by focus}
while (rgn is valid) and (wnd<>NIL) {
destroyed_reg:=intersection(rgn,wnd^.region);
if (destroyed_reg is valid) then
sendmessage(wnd,DESTROYED,0,0,addr(destroyed_reg));
rgn:=subtract_region(rgn,destroyed_reg);
wnd:=Next(wnd);
}
free(regions, etc..);
}
the way I have it, most of the destroyed background ends up being sent to
the background window which can then paint it (during EXPOSE) with whatever
color or pattern that a user selects (or even a bitmap). My problem is with
a suitable subtract,intersect etc.. routine that works efficiently and can
handle non-contigious RECTs and consolidate them to one if possible.
The RECT routines that I have seen only work with simple rectangles and cannot
create multiple non-contigious rects (Regions). Does anyone have some pointers
to some code? also, I know that Windows 3 exists but I cannot afford the SDK
nor do I need the power of a REAL GUI. I am looking at a SMALL GIU library that
can get my PC to look like a MAC without much work on the programmer's part.
thanks.
