Some questions on iss Russian segment

1) what Is the warranty of iss spare elbow joint on iss mrm module I need to know that to see the final period till which it can be used in case actual Era gets some problems

2) is MLM radiator and MLM heat exchanger same

3) how will Era position mlm airlock from mrm to nauka as it has only one frgf grapple fixture when Era grapple fixtures are different

4)is Era portable workpost and nauka means of attachment of large payloads different. If yes like as shown in the image below then is there a timeline for transferring Era portable workpost from mrm to nauka
and installation it. And which Progress MS delivered the means of attachment of large payloads.

Been reading about ISS this month, so have a few questions

1) Now that we have an extra member due to Crew Dragon, do we know how many astronaut-hours are spent on science vs maintenance per week?
In 2014, it was around 40 hours/week for USOS. (Slide 14 in https://www.nasa.gov/sites/default/files/files/NACRS_ISSResourceOverview_022014T.pdf)
2) Are there any plans to add International Docking Adapter to Prichal?
3) I want to learn more about the life support systems, are there any books about this?
4) Are daily schedules of astronauts published anywhere? (It was till 2014, but couldn't find the link now)

I am not sure where to post this, but why am I not seeing anything here about NASAWatch's new story about NASA cutting back on PA coverage of the ISS? Seems like an important topic!

Most recent thread from the last time they tried and had to reach a compromise:

What happens to the CubeSat deplorers on the ISS after they've deployed their satellite?

Will Strela no longer be needed once the ERA is operational? Also, can the ERA be equipped with a portable foot restraint?
Thx

they will be supplementary then a notable thing is the era grapple fixtures are only on nauka and prichal so maybe strela are needed for other modules in ros segment and for ERA foot restraint it is already on iss transported with rassvet as mlm outfitting on sts-127 like the nauka airlock, radiator and era spare elbow joint. Hope this helps out.

Yes, their use will lessen but is not fully eliminated. The Strela booms can be mounted on Nauka as was a proposed plan at one point when the original ROS proposal came about. ERA range can be extended by installing additional grapple fixtures on the rest of ISS RS. Even ERA grapple fixtures on the Columbus module was once considered as a part of an earlier plan before it was bumped to the Russian Segment as a barter for Russian technology transfer for the ATV programme, etal.
