Formating and markup

Hello Mark Rust, my name is Zach, and I'm on the Exec Board and I'm on the bug tracking team. When you were talking about formatting issues, I haven't looked at the exact pages you're talking about, but there are 2 major issues that probably cover what you're talking about:

1) We're using WP article versions from late September or so. This means that any changes you did on Wikipedia in October or November isn't going to show up here. We're eventually planning to re-import untouched articles from Wikipedia to catch up some of those changes, but that hasn't happened yet. Alternatively, if you want to copy and paste the latest version from Wikipedia, feel free to (our pages already note automatically that the pages are at least partially derived from WP, so that's 100% legitimate if you want to do that).

2) We're not on exactly the same software platform as Wikipedia. We both use the MediaWiki software, but Wikipedia uses a hodgepodge of code modifications and extensions that we need to track down. If there's an up-to-date list of what modifications and extensions WP uses, I haven't seen it. Additionally, we use a different Database from Wikipedia (PostGRE SQL instead of MySQL (which shouldn't affect formatting)). Our tech team is three volunteers (who all have day jobs), so unfortunately, progress is not instantaneous.

As to what you can do, I would recommend worrying about the content over the formatting for the time being (if possible). If you do decide to do some formatting work and can figure out what works and what doesn't, by all means let me know.

Let me know if I can be of further help,

Zach Pruckowski

With regards to your two comments on my talk page:

1) The behavior with <sub> is actually the correct behavior. <sub> is actually an HTML tag, and you have to "close" it with the </sub> tag or else it just keeps going to the end of the page or paragraph. MediaWiki (the software we use) supports both its own specialized markup (wikitext) which traditionally has identical opening and closing tags (like [[ and ]] (links to other CZ pages) or '' and '' (italic)) and HTML/XHTML/CSS, which have slightly different opening and closing tags (generally <something> to open and </something> to close).

2) You are correct that PNG graphics are not working. There's some sort of program that needs to be installed on our end for PNG support to work. Unfortunately, our technical team (of which I'm not a member fully) is all volunteer, and rather overwhelmed (as they all have full-time jobs, as well as families), so we haven't gotten that change made yet, but we fully intend to eventually (and hopefully soon) support PNG. In the meantime, there exist a lot of free applications for every OS (Windows, Mac, and Linux) that will convert images from PNG to JPEG on your computer, so that'll have to suffice in the short term.

fair use (or unfair use)

There's not much of a consensus as to what to do about fair use images. There's been talk about it on the forums a bit, but we don't have a totally coherent policy. We definitely prefer freely licensed stuff. I'd pose the question on the forum or on the discussion list, and provide as much information as possible about the image. Happy Holidays. --ZachPruckowski 16:52, 23 December 2006 (CST)

Nuclear chemistry

Hi Mark, I noted that you were doing some great stuff, not my field by a long way but I have catholic interests. I can see that as you're writing you're hitting this universal problem of how much detail to include. The problem is as you fill one section with detail you'll need to fill the others similarly or the article will feel unbalanced. I think a good way, as you've indicated, is to write the first article as an introductory overview, not assuming too much technical knowledge but giving glimpses of sophistication, and then to feed into maybe short more technical articles. Again, I think the key is to ask who is going to read this and why? Whatever your answer the answer is fine, but have that clear in your mind and flag it on the Talk page. Happy christmas!Gareth Leng 14:20, 25 December 2006 (CST)

Greetings Mark! I've been surfing "articles to approve" and came upon Nuclear Chemistry. I see that its still going through some growing. Just a quick reminder about how the approval process is working. You can't actually nominate an article for approval if you've done all the work on it - or rather, you need to nominate it with other editors from your work group (or in this case physics, chemistry.. related workgroups). You need to rustle up some other editors to read through and give it the stamp (it's helpful if they say something in the discussion page) before we approve the article. Thanks for the hard work. It looks great. -- Sarah Tuttle 12:43, 29 December 2006 (CST)

Mark, I was pleased by your invitation. I noticed your recurrent "nuclear chemistry" on "recent changes", but have been making some scattershot changes of my own and hadn't got around to look at the article yet. I will do so within the next couple of days, and I will spend some time when I do - simultaneously doing some library research to add medical stuff. I'll also ask other health science editors. Thanks, Nancy Sculerati MD 07:48, 30 December 2006 (CST)

Hello! How many active chemistry editors do we have now? Keep up the great work! -Tom Kelly (Talk) 18:15, 14 January 2007 (CST)

Radiolysis and deeep subsurface energy sources for life

The yield and isotopic composition of radiolytic H2, a potential energy source for the deep subsurface biosphere LI-HUNG LIN,1,*† GREG F. SLATER,2,3 BARBARA SHERWOOD LOLLAR,2 GEORGES LACRAMPE-COULOUME,2 and T. C. ONSTOTT1 Geochimica et Cosmochimica Acta, Vol. 69, No. 4, pp. 893–903, 2005

... H2 production through abiotic processes is critical to maintaining an H2-based subsurface lithoautotrophic ecosystem that is independent from surface photosynthesis. H2 constitutes a major component of dissolved inorganic gases (as high as 98% by volume of the total dissolved gases) in the groundwater of Precambrian Shields, and its concentration ranges up to several mM (Haveman and Pedersen, 1999; Sherwood Lollar et al., 1993a; Sherwood Lollar et al., 1993b).

... observed in the studies for marine sediments or shallow aquifers (Hoehler et al., 1998; Lovely and Goodwin, 1988). Radiolysis of water has been proposed as a mechanism for generating these large quantities of H2 (Savary and Pagel, 1997; Vovk, 1982). This hypothesis is supported by the observation that H2-bearing fluid inclusions in quartz are associated with U-bearing minerals (Debussy et al., 1988; Savary and Pagel, 1997).

F. (1982) Radiolysis of underground waters as the mechanism of geochemical transformation of the energy of radioactive decay in sedimentary rocks. Litho. Mineral. Res. 16, 328–334.

Energy released from the decay of radioactive elements (e.g., U, Th, and K) dissociates water molecules into H●, OH●, H2, H2O2, a hydrous electron (eaq �), and H� (reaction 1 in Table 1). These products are formed within �10�6 s after the primary ionizing event and diffuse into the bulk solution where they react with other aqueous species (see reactions in Table 1). Additional H2 is formed via the subsequent recombination of ...

Before the advent of oxygenic photosynthesis, the biosphere was driven by anaerobic metabolisms. We catalogue and quantify the source strengths of the most probable electron donors and electron acceptors that would have been available to fuel early-Earth ecosystems. The most active ecosystems were probably driven by the cycling of H2 and Fe2+ through primary production...

Returning to Citizendium: an update on the project and how to get involved

Hello - some time ago you became part of the Citizendium project, but we haven't seen you around for a while. Perhaps you'd like to update your public biography or check on the progress of any pages you've edited so far.

Citizendium now has over 16,000 articles, with more than 150 approved by specialist Editors such as yourself, but our contributor numbers require a boost. We have an initiative called 'Eduzendium' that brings in students enrolled on university courses to write articles for credit, but we still need more Editors across the community to write, discuss and approve material. There are some developed Chemistry articles that could be improved and approved, and some high-priority Natural Sciences articles that we don't have yet. You can also create new articles via this guide, and contribute to some Chemistry pages that have been recently edited - or to any others on Citizendium, since you're a general Author as well as a specialist Editor. You may like to contribute to discussions in the forums, and might consider running for an elected position on the Management and Editorial Councils that oversee the project.

If you have any questions, let me know via my Talk page or by leaving a message below this one. Thank you for signing up and reading this update; I hope that you will look in on our community soon. John Stephenson 10:02, 30 October 2011 (UTC)
