'''Guidelines to update a reference'''
<div class="mw-collapsible-content">
::When creating an O2k-Publication/Brief alert, it is the responsibility of the author to check if the reference is accordingly to the correct guidelines:
[[File:Reference example.png|900px]]
::Correct format for a person called ā€œFirst Name Surnameā€:
::In the gray box should be ā€œSurname FNā€ - '''From where references to be used as O2k-Publication/Brief alerts are copied from.'''
[[File:Gray box reference.png|900px]]
::In the links should be ā€œ Surname First Nā€
[[File:Authors names links reference.png|900px]]
::'''How to edit:'''
:::A) Check if all authors with profiles in Bioblast (blue links) have their profiles with full name. If they have, proceed to next step (B). If not, you need to move it following the steps ā€œHow to move a profileā€ below.
:::B) Click in ā€œEdit with formā€.
:::C) The gray box is edited in ā€œReferenceā€ and the links are changed in ā€œAuthor(s)ā€. Change it accordingly and click in ā€œsave pageā€ at the end of the page.
[[File:Editing reference.png|900px]]


::::::: - from the O2k-Network Ā»[[KR Busan Han J]]Ā« Ā»[[KR Incheon Kwak HB]]Ā«
'''How to move a profile (instructions sent by Marija):'''
::::::* No MH, Heo JW, Yoo SZ, Kim CJ, Park DH, Kang JH, Seo DY, Han J, Kwak HB (2020) Effects of aging and exercise training on mitochondrial function and apoptosis in the rat heart. Pflugers Arch 472:179-93.Ā  - [[No 2020 Pflugers Arch |Ā»Bioblast linkĀ«]]


So letā€™s take for example my page:
[[Beno M]]
[https://wiki.oroboros.at/index.php?title=Beno_Marija&redirect=no]


=== On hold ===
::As you can see there is a redirect from Beno Marija to Beno M. What has to be done is to switch the content of those pages. Here are the steps:
Ā 
:::1. Go to e.g. ā€œBeno Mā€ on edit
::::[[File:MitoPedia.jpg|60px|MitoPedia]] Did you ever think that units for body mass could be an issue? Ā» '''[[Body mass]]''' Ā«
:::2. Click on ā€œMoveā€
:::3. Change the new title to the full name of the person. In my case it will be Beno M to Beno Marija
[[File:BenoMreference.jpg|500px]]
:::4. Now it should look like that:
[[File:BenoMarijaReference.png|500px]]
:::5. Click on ā€œMoveā€ and leave all the ticked boxes
:::6.Done
::After that you can continue in step B.
::If you have any doubt you can contact Cristiane, Marija or Mario.

The oxygen solubility factor of the incubation medium, F<sub>M</sub>, expresses the effect of the salt concentration on oxygen solubility relative to pure water.

Guidelines to update a reference

When creating an O2k-Publication/Brief alert, it is the responsibility of the author to check if the reference is accordingly to the correct guidelines:

Reference example.png

Correct format for a person called ā€œFirst Name Surnameā€:
In the gray box should be ā€œSurname FNā€ - From where references to be used as O2k-Publication/Brief alerts are copied from.

Gray box reference.png

In the links should be ā€œ Surname First Nā€

Authors names links reference.png

How to edit:
A) Check if all authors with profiles in Bioblast (blue links) have their profiles with full name. If they have, proceed to next step (B). If not, you need to move it following the steps ā€œHow to move a profileā€ below.
B) Click in ā€œEdit with formā€.
C) The gray box is edited in ā€œReferenceā€ and the links are changed in ā€œAuthor(s)ā€. Change it accordingly and click in ā€œsave pageā€ at the end of the page.

Editing reference.png

How to move a profile (instructions sent by Marija):

So letā€™s take for example my page: Beno M [1]

As you can see there is a redirect from Beno Marija to Beno M. What has to be done is to switch the content of those pages. Here are the steps:
1. Go to e.g. ā€œBeno Mā€ on edit
2. Click on ā€œMoveā€
3. Change the new title to the full name of the person. In my case it will be Beno M to Beno Marija

BenoMreference.jpg

4. Now it should look like that:

BenoMarijaReference.png

5. Click on ā€œMoveā€ and leave all the ticked boxes
6.Done
After that you can continue in step B.
If you have any doubt you can contact Cristiane, Marija or Mario.

This one needs an update of the Bioblast page and clarification of MiPNet06.03

O2k-Open SupportInfo: improve Did you enter the correct oxygen solubility factor in DatLab?

The oxygen solubility factor of the incubation medium, FM, expresses the effect of the salt concentration on oxygen solubility relative to pure water. The correct oxygen solubility factor of your experimental medium or buffer needs to be entered in DatLab for proper calculation of the oxygen concentration.

The volume added until the mark, equal to the highest flux, should be entered. Anything titrated after this mark should be summed to the other volumes before the next mark because this will be considered to calculate the sample dilution.
