[edit] Thanks for the categorizing help

Not yet completely clear on all of this, especially as to how it works in a search, and so I am grateful for the help. CApitol3 13:45, 28 September 2006 (UTC)

[edit] fr:Activité chimique

I am French and I can translate French article in English. But i saw the French article and I don't see any real detail which doesn't appear in the English one (apart from the scientific jargon-slang used). Maybe you can tell me what the English article really need and I'll translate it for you. SamiKaero 09:04, 24 October 2006 (UTC)

[edit] fr:Activité chimique

Ok, I'll do it.--SamiKaero 12:45, 24 October 2006 (UTC) Well after checking, you were right, the French article contains true scientific formulae and real definition needed for real Chemistry studients and could be part of a Chemistry college lesson, having myself attended Chemistry classes about Enthalpie(free energy) and Dynamic of Fluids, I can understand most of the article, but i leave you the duty to rearrange the translation (I'll translate it roughly) and also you will have to translate the words i couldn't myself find a matching one in English.--SamiKaero 13:06, 24 October 2006 (UTC)

[edit] fr:Activité chimique

Ok, just finished the translation, you'll have to correct because it's full of grammatical errors and unprecisely translated words, in case of a clever sysop deleting the translation too fastly, I'll leave you a copy right away, good luck for the correction--SamiKaero 13:59, 24 October 2006 (UTC) :

[edit] Unorganized translation for User:Ksbrown to correct

Indication:when i can't find a translation for a word, i'll put the ' for the possible translation and the () for the litteral translation. The chemical activity of a 'body'(species) is the influence of a quantity of a 'body'(species) on the Helmholtz free energy of a system. The chemical potential µi of a 'body' i is the partial derivative of the Gibbs Free Energy of the system compared to the quantity ni (number of moles):

\mu_i = \frac{\partial G}{\partial n_i}

This chemical potential depends on the temperature T, of the pressure p and of the activity ai according to the formula :

\mu_i(T,p) = \mu_i^0(T) + R \cdot T \cdot \ln(a_i)

where R is the Constant of the Ideal gas and µi0 is the value of µi in 'the 'referential'(referential conditions).

[edit] 'In case of a gaseous reaction'(Case of a compound in a gaseous milieu)

The activity is of the form :

a_i = \gamma_i \cdot x_i \cdot \frac{p}{p_0} = \frac{f_i}{p_0}

where γi is the coefficient of '?'(fugacity) (without dimensions) of the 'body' i, xi the molar fraction of the 'compound' in the gaseous 'milieu' and p the pressure expressed in bar.

The quantity fi has the dimension of a pressure and is named 'fugacity' : for a pure Ideal gas, the coefficient of 'fugacity' is equal to 1.

p0 is the standard atmospheric pressure. It is equal to 1 bar and only serves here to 'withdraw?'(delete) the dimensions of the formula. Then, we have:

\mu_i(T,p) = \mu_i^0(T) + R \cdot T \cdot \ln(\gamma_i \cdot x_i \cdot \frac{p}{p_0})

[edit] 'in case of a liquid reaction'(case of a compound in a liquid solution)

The activity is of the form :

a_i = \gamma_i \frac{C_i}{C_0}

Where γi is the coefficient of activity of the 'body' i, Ci his concentration in solution expressed in mol.l-1. the 'term' C0 is equal to 1 mol·l-1 and only serves here to 'withdraw'(delete) the dimensions of the formula. Then, we have :

\mu_i(T,p) = \mu_i^0(T) + R \cdot T \cdot \ln(\gamma_i \cdot \frac{C_i}{C_0})

We will point out that in a liquid solution the activity coefficient of a given ion (ex : Ca2+,…) isn't measurable because it is experimentaly impossible to measure independantly the electrochemical potential of a ion in solution. That's why we introduce the notion of 'average activity coefficient'.

[edit] Simplification

We simplify sometimes the formulae above considerating that :

  • For a chemical solution :
    • the solvant has an activity of 1
    • The activity of a 'soluté'(in French, it is the contrary of solvant, the 'body' which gets dissolved) is equal to the ratio of its concentration over a referential concentration as long as it keeps low values ;
      a_i = \frac{C_i}{C_0}
      Concretely, it is equal to its concentration in mol·l-1 ;
  • For a mix of gas : the activity is equal to the ratio of the partial pressure of the gas over the referential pressure, as long as this pressure keeps low values ;
    a_i = \frac{p_i}{p_0}
    Concretely, it is equal to the partial pressure in Bar (unity) (dealing with a referential pressure of 1 bar)
  • For a solid body : a solid, alone in its phase, has an activity of 1.

The chemical activity occurs in the definition of the 'Constant of equilibrum'(?).

[edit] Help with a translation

Hi my name is Ricardo and I'm working in related articles to Cúcuta (a colomabian city).

Can you help me to translate this one to Hydrography of Cúcuta and North Santander.

Thanks!

Ricardo Ramírez! ✍ 22:53, 25 October 2006 (UTC)

[edit] November 2006

[edit] Welcome

Thanks Ksbrown for the welcome. Actually I have been a wikipedian on mostly nl:, since they had about 400 pages. I don't come here very often, but my students are now using wikipedia as a source for their P Chem and I need to make sure they do not get confused. So i decided to clean up a bit. It's actually a bit of a mess in thermodynamics I'm afraid.. Details smietails but still: important details.

[edit] British Fabians in 1934

Image:1934 Protocols Patriotic Pub.jpg "The Protocols" (On Spine); 1934; THE PATRIOTIC PUBLISHING CO.; P.O. Box 526; Chicago, Ill.</gallery>
Thanks for your observation. I now own the above notorious book.
It's quite anti-Fabian--but I don't know much about British Fabianism.
Do you know anything about anti-Fabianists of 1934 in England?
How about this--do you know if there is a book, "Wikipedia for Dummies"?
I really need to learn more about Wikipedian Image editing. Do I need any special software?
Or how can I enlarge the above image??
Thanks. Ludvikus 20:16, 17 November 2006 (UTC)

[edit] Friends of New Germany

Thanks for your prior work & help on the above article.

But I need more help on this article.
The Friends of New Germany simply REDIRECTS to the German-American Bund.
I want a distinct article for Friends of New Germany.
Can you help:
Thanks! Ludvikus 20:27, 17 November 2006 (UTC)

Categorization of Friends of New Germany -- done!

Ludvikus 20:33, 17 November 2006 (UTC)

I do not understand the following: <!--Categories Below this line--!> [[Category:Political history of the United States]] [[Category:Nazi organizations]] [[Category:German American history]] <!--End of categories--!> <!--Interwiki links below this line--!>

Yours truly, Ludvikus 21:33, 17 November 2006 (UTC)

For a Wikpedian who selflessly devotes time to helping the Wikipedia community with the hope that all things worth knowing are found here. Thanks for the help with tags on my talk page. Sharkface217 22:17, 17 November 2006 (UTC)
You're quite welcome. I do what I can. Sharkface217 22:21, 17 November 2006 (UTC)

[edit] Stubs

I am now using more specific stubs so that they don't have to go through stub sorting. However, I freely admit that every now and then I do get lazy. Sharkface217 22:18, 17 November 2006 (UTC)

[edit] Re: Stub Message

I do try and tag the ones I am familiar with. Most, if not all the stubs I tag are those from the Newpages list. As such, my primary goal isn't the stubsort, just the removal of useless junk pages. When I come across a small article that doesn't resemble patent nonsense or a n-n bio, I'll stub tag out of courtesy. I know that someone else will then have to stub-sort, but my goal is the rm of pointless pages. I appreciate your comment though. - Jake - Bladeswin | Talk to me | 22:53, 17 November 2006 (UTC)

I take it that this is about Deanhead Reservoir, right? I'll get on it :) Will (Tell me, is something eluding you, sunshine?) 23:03, 17 November 2006 (UTC)
Oops, never mind. Will (Tell me, is something eluding you, sunshine?) 23:04, 17 November 2006 (UTC)

[edit] Stub sorting

Please see the response to your comments on my talk page. – Tivedshambo (talk) 12:28, 18 November 2006 (UTC)

[edit] Stubs

Hmmm, well, English is not my mother tongue and even in Castillian, i don't classify stubs, i think it's the best way to make you guys correct my articles, at least you read them a little :) Gaudio 21:43, 18 November 2006 (UTC)

[edit] more of the same

I also got your note and am making the effort to use specific stub tags. however, I feel very strongly that a lot of articles are only ever going to be short, and that recognising this, and removing the tags, would help. especially all those actors! raining girl 23:06, 18 November 2006 (UTC)

[edit] Stubs

Sorry about that, I will try to remember in future. As you've probably guessed, it's a bit of a bad habit I've gotten into! Blood red sandman 23:05, 15 December 2006 (UTC)
