Dear Alan, Since a filter (inexpensive or otherwise) only subtracts light from a particular part of the spectrum, you will need a pigment which reflects/ emits light in a different spectral region than normal skin--BTW, any par- ticular color skin?--but is not usually visible. This would have to be due to its light being obscured by that reflected by skin. To make a start, you will have to obtain that spectrum, find a convenient minimum, find a pigment which reflects/emits light at that wavelength, and construct a filter which passes that wavelength--a band-pass filter. With a lot of luck, this might be makable from relatively inexpensive components. Good luck.

One place that gas solubilities are tabulated is the International Critical Tables. The folks who do oxygen binding to hemoglobin/myoglobin know those numbers well, but I have been out of that field for a while and don't have the numbers handy. However, I can put my hands on a paper by J. Robinson and J.M. Cooper, Analytical Biochem. 33, 390-399 (1970), which says air saturated water at 1 atmosphere and 37 deg. contains 200 micromolar dioxygen, so by looking up the fraction of air that is oxygen you should be able to calculate what you want. The same paper also discusses the effects of salt on the solubility (0.5 M NaCl reduces the solubility by 15% at 25 degrees).

Here you have Ionchannels (passive movement, facilitated diffusion) and active transport mechanisms (ATP dependent) which accomplish a gradient of ions across the membrane (and you have membrane proteins also). In thermodynamic equilibrium you can always assume that the chemical potentials of all ions on either side of the membrane are equal. The potential itself is a function of the transmembrane potential (electrical potential differen ce so to speak) and a concentration gradient. (s.ref. Nernst-Planck equation) So what does all that tell you? In order to describe thermodynamic equilibrium you would think of a totally balanced cell (death). In some way the Donnan potential resembles this situation: if you have proteins with some net charge on either side of the membrane it will influence the equilibrium distribution of ions between the outer and inner compartment. The more negative charges you have on the outer side the more positive ions can be found in the extracellular medium (or at least close to the membrane). So you re still at thermodynam ic equ. but surely there is a concentration gradient due to the mentioned charges. Resting potential? As the name already implies this is a potential difference which is caused by a perturbation from equ. This steady state is maintained by active translocation processes like ATPases (Na/K ATPase) and is counteracted by passive diffusion along the gradient. So, the Donnan potential has definitely an influence on the concentrations of the particular ions in each medium, but can not be the only cause for a resting potential. p.s.: the potential due to different mobilities (diffusion constants) is called a diffusion potential, which is different from Donnan.

This effect is most easy to detect by "self-observation": I have discovered it trying to turn my head so that to see the end of my nose exactly at the center of a full moon. Actually, electric lamp in a dark room may also serve well. When the diameter of pupil changes, obviously, you will see bigger or lesser part of the moon's disk. So the visible effect is that the line of nose can not be fixed on the moon disk, it moves periodically so that one time you see almost a full disk and then it appears almost completely covered by your nose. The effect is more pronounced if the shadow is casted only upon the central area of pupil. For example, you may place near your eye a conic part of a pencil covering with it the image of the lamp. You should see that the visible shadow from the cone starts to pulsate with a period of a second or little more. Explanation of this phenomenon is standard. There is always some delay in reaction of pupil to the change of the amount of light going through it. So, for example, when the pupil is widenining it does not stop to widen exactly at the moment when amount of light going through it precisely corresponds to its diameter. It widens more than necessary, then it should to contract; naturally, in the same way it contracts more than necessary and the story is repeated again and again. Obviously, this is autooscillation - essentially the same process as Belousov-Zhabotinsky reaction, predator-prey oscillations etc. Of course, it is much less pretentious yet it has a much more transparent mechanism. I think, it a nice thing to use it as an introductory illustration to the world of autooscillations in biohysical courses. Apparently I should also suggest here that this effect may have some practical importance for medical diagnostics.

There will be more light admitted by a bigger pupil, but each point on the moon reflects light to all parts of the eye (whether the light hits the retina or not), so each point on the moon's disk will reflect light to the unshadowed part of the pupil and will, therefore, be visible. The auto-oscillations you noted may be due to the motion of the entire eye called saccade.

I am aware that there exist reasonable potentials for calculating their energies and such, as described by Burley & Petsko and some physical chemists they refer to (Karlstrom?). I am looking for a simple jiffy that will do one or both of these: 1) Calculate a relative orientation of two rings, or a ring and a water, preferably in the reference frame used by Burley & Petsko. 2) Maybe even calculate an interaction energy. I can do (1), although I'm kinda lazy and don't feel like doing all that vector calculus, and coding (2) is doable but time-consuming. So if anyone at all knows of a program to do this, I'd be very much obliged. Thanks kindly in advance, Yoram -- _______________________________________________________________________ Yoram A.

Example: (fluid/structure interaction) Computation of a fluttering wing. On one side you have the the structured mechanics to simulate the deformation of the wing. On the other side you have the aerodynamics around the wing, which produce the pressure distribution on the wing-surface. This two computations interact and coupled via the wing-surface. I would like to know more about the coupling of PDE's in different areas (Chemistry, electro-magnetics, CFD, etc.) direct or loose coupling (preferably loose) I am looking for: -- good reference-paper -- people, groups working on coupling problems (name, e-mail, WWW-pages) -- people, need help to compute the coupled solution of PDE's systems -- difficult problems not solved yet properly (conservative interpolation for non-fitting interface- surface meshes, etc.). -- software in the area of coupled PDE-systems -- research-areas, where the coupled solution of PDE's is applied or neccessary As you read, I would like to know nearly everything in the area of coupled PDE-system's.

The main BIOSCI FAQ (Frequently Asked Questions) is accessible on the World Wide Web at URL http://www.bio.net/. If you can not find an answer to your question in this or other documentation, the BIOSCI technical support staff answers e-mail queries sent to biosci-help@net.bio.net We can only answer questions about the use of the newsgroups and mailing lists. We unfortunately do not have the staff to do Internet information searches or answer scientific questions. Please post those to the appropriate BIOSCI/bionet newsgroups. Contents: -------- 0) BIOSCI NEEDS YOUR SUPPORT!! 1) Using the WWW to access the BIOSCI/bionet newsgroups. 2) What to do about "spams," i.e., junk mail, ads, etc. 3) Examples of subscribing and unsubscribing to the mailing lists. 4) The BIOSCI user address and research interest directory. 0) BIOSCI NEEDS YOUR SUPPORT!! ------------------------------ BIOSCI's government funding has been expended, and we are now operating solely from advertising revenue that we have raised from our Web site at http://www.bio.net/. We need just a few minutes of your time to help us serve you. You can do two important things which will take very little time for you individually and will immensely help us continue to help you. First, please use our WWW system at http://www.bio.net/ to access the archives. You can post or reply to messages via your Web browser as described in item #1 below. Your usage helps attract sponsors. If you contact any of our sponsors, please be sure to thank them for supporting BIOSCI. It is critical for them to get this feedback if they are to continue their sponsorship for the long term. Second, if you work for a company or organization that provides products or services of interest to the biology community, please pass this message on to your marketing or marketing communications department or other appropriate group. Please ask them to help support BIOSCI by sponsoring our Web site and explain the uses and benefits of the system to the biology community. If they are interested, they can then contact us for further information at our tech support address, biosci-help@net.bio.net. 1) Using the WWW to access the BIOSCI/bionet newsgroups. -------------------------------------------------------- As of 10 December 1995, all BIOSCI/bionet full newsgroups are accessible through the World Wide Web (WWW) at URL http://www.bio.net. One can read and reply publicly or privately to both recent postings and archived messages through one's Web browser if it is configured properly to send e-mail. Each newsgroup is equipped with its own WAIS index. The main BIOSCI home page also has access to the BIO-JOURNALS Table of Contents database WAIS index and the BIOSCI user address database described in another item further below. 2) What to do about "spams," i.e., junk mail, ads, etc. ------------------------------------------------------- BIOSCI is a set of parallel USENET newsgroups (the "bionet" groups), mailing lists, and a hypermail archive at URL http://www.bio.net/. The same postings are distributed on all media (except for a small number of mailing-list-only groups at net.bio.net). Unfortunately it is becoming a despicable practice on the Internet (by a few people out to make a fast buck) to do automated mass postings to thousands of newsgroups and mailing lists. These attempts to grab free advertising are refered to as "spams" in the usual, somewhat boneheaded, net terminology. USENET is more susceptible to this practice, and many spams originate on the USENET groups and then are passed on to the mailing lists. However, spammers also get lists of mailing addresses and hit these too, so neither medium is immune. What should you do personally if you get junk mail? --------------------------------------------------- Just delete it and move on without reading it further. Filing a protest is becoming increasingly useless because spammers are often disguising the addresses where the messages are sent from. Unless you really understand Internet mail systems, your attempt at protest by sending replies to the message will often end up being sent to the address of an innocent person that the spammer is victimizing. What can BIOSCI/bionet do to protect its newsgroups? ---------------------------------------------------- The only solution currently available is to moderate the newsgroup. If this newsgroup is already moderated, then you are in good shape. Moderation protects the USENET distribution from about 95% of the spams that are being sent to date and protects the mailing lists completely. Moderation means, however, that someone has to take the time to review each message before it goes out. We have set up software here that simply allows the moderator to forward to an address at net.bio.net messages that (s)he wishes to have distributed. This takes no more time than that needed to read the message and pass it on, say about 1 min. per message. Most newsgroups currently have a discussion leader who is responsible for their newsgroup. The discussions leaders and their e-mail addresses are listed in the BIOSCI Information Sheet which is available on the Web at http://www.bio.net/. If a newsgroup is being hit with too many junk postings, please contact the discussion leader for that group and see if there is interest in moderating the group. Please do not assume that by simply posting a complaint to the newsgroup itself, anyone on the BIOSCI staff will act on your complaint. With close to 100 newsgroups to run, the BIOSCI staff has to rely on the discussion leaders of each newsgroup to report problems directly to us at biosci-help@net.bio.net. We will moderate any of our newsgroups if the discussion leader tells us that the readership of the group wishes to do so and if a moderator is willing to do the work. For most BIOSCI/bionet groups, this entails only a few minutes of work each day. Moderating a newsgroup will resolve probably 95% of the junk postings on the USENET distribution. Unfortunately there are easy ways for determined spammers to override the moderation mechanism on USENET, but we can protect our e-mail subscribers from unwanted postings if the newsgroup is moderated. You can also access our newsgroups over the WWW at URL http://www.bio.net. While this Web interface will not stop spammers from trying to post to the groups, this will give you yet another way, besides using USENET news, to keep the junk out of your personal mail files. For those of you with local USENET news systems, the Web interface will also give you faster access to new newsgroups and recent postings. 3) Examples of subscribing and unsubscribing to the mailing lists. ------------------------------------------------------------------ PLEASE NOTE: The BIOSCI management does NOT act on subscription/unsubscription requests that are posted improperly to the newsgroups and mailing lists. People who do this only bother everyone on the lists to no avail. Please be sure to follow the proper procedures below. Gory details are in the BIOSCI Information sheets on the Web at http://www.bio.net. Below we give an example utilizing the METHODS-AND-REAGENTS list at both of our two BIOSCI sites: Users in the Americas and Pacific Rim countries who use the BIOSCI ------------------------------------------------------------------ node at computer net.bio.net: ---------------------------- A) Determine the "listname" which is the <=8 character mail address ^^^^^^^^^^^^^ for the group. These can be found in the BIOSCI Info. Sheet. For the METHODS-AND-REAGENTS group the mailing address is methods@net.bio.net. The listname is the portion of the address to the left of the @ sign, i.e., "methods". The listname is used with the "subscribe" and "unsubscribe" commands illustrated below. B) Mail all commands in the body of a mail message addressed to biosci-server@net.bio.net. Do NOT send commands to the newsgroup posting addresses! Leave the Subject: line blank, any text on it will be ignored. C) In the body of your message put one or more of the following commands with an "end" command on the last line, e.g., subscribe methods unsubscribe methods end Do NOT put your e-mail address or other text on these lines. The server only allows you to cancel your subscription if the address on your mail header matches the address on our mailing list. Please ask for help at biosci-help@net.bio.net if your address has changed, e.g., if you know you are on the list but the server tells you that you are not a member. Users in Europe, Africa, and Central Asia who use the BIOSCI node at -------------------------------------------------------------------- computer daresbury.ac.uk (also known as dl.ac.uk): ------------------------------------------------- To subscribe and unsubscribe to/from the BIOSCI lists, you need to specify the full USENET newsgroup name with "bionet-news." prepended. The USENET newsgroup names are listed in the BIOSCI Information sheet on the Web at http://www.bio.net/. For the METHODS-AND-REAGENTS list the USENET newsgroup name is bionet.molbio.methds-reagnts, thus the appropriate commands are sub bionet-news.bionet.molbio.methds-reagnts unsub bionet-news.bionet.molbio.methds-reagnts These commands are included in a message addressed to mxt@dl.ac.uk, NOT to the newsgroup mailing addresses. As usual, include the text in the body of the message as text on the Subject: line is ignored. To unsubscribe from all the lists at the UK node, use unsub bionet-news Please note that if the address in the list is different than the one in your mail message header, you will not be able to unsubscribe by this method. If you have problems, please mail biosci@daresbury.ac.uk. 4) The BIOSCI user address and research interest directory. ----------------------------------------------------------- Please take this opportunity to add your name, address, and research interest information to the BIOSCI User Address Database if you have not already done so. You can fill out the address form directly through our Web page at URL http://www.bio.net/adrform.html. The address database is reindexed nightly for WWW access (the URL is http://www.bio.net/). If you are not directly on the Internet but can reach it by e-mail, please use our waismail server to access the user directory. waismail use is described above. You can also request a user address form by e-mail from biosci-help@net.bio.net. Please check your database entry from time-to-time to see if your address information is still up-to-date. Because of our limited personnel resources, we ask that you resubmit a *complete* form to revise your entry; we only replace complete entries and do not have resources to edit old forms.

In the past I have used a glucose oxidase + catalase system to scavenge oxygen from hemoglobin solutions, and we had problems getting it to work in the presence of cyanide. The catalase is certainly inhibited by cyanide, but as I recall our tests also showed significant inhibition of the glucose oxidase at cyanide concentrations in the 10-100 micromolar range. Sorry, I don't have any references about this.

My problem deals with polar water molecules in biological tissues and how they align with an applied electric field. As the electric field changes direction, as a function of frequency, combined with frictional forces, a rotational relaxation develops which characterizes the permittivity behavior of tissue. I need to develop a mathematical model for this relaxation phenomenon. I need to start with a differential equation describing the balance of forces involved and derive an expression for the dielectric constant and conductivity as a function of frequency. I know this is an in-depth kind of question, but I'm desperate for any sort of help. Any help is extremely appreciated. Thanks. Steven. - I think you could have a look at "Theory of electric polarization" of C. J. F. Bottcher, vol 2 (ed. Elsevier, Amsterdam), which contains the Havriliak-Negami formula of the dielectic permettivity of polar molecules. In that book you can find also some useful references, i think.
