Re: XP

"I /am/ having a lot of trouble. However, I don't like the path Microsoft has chosen,"

Well I'm sorry for that but I'd repeat the advice from Chika and use a more forgiving distro like Mint or my usual choice of OpenSUSE. But I reiterate flash isn't a problem usually and most installs don't need cli work.

"For all things internet I moved away from Win7 and started using Linux (Debian 8.2) a while ago."

Why ? - you seem to be having a lot of trouble. Are you sure that this isn't an attempt by an AC to spread some FUD about Linux. It certainly doesn't explain why you continue to use Linux.

Re: Insulin Potentiation Therapy?

"Insulin Potentiation Therapy? "

All I'd say about this is that AFAIK glucose is transported into cells by active transport proteins (being very hydrophilic it wouldn't easily diffuse through the cell membrane) . It would seem very unlikely that any chemo. drugs would be transported by the same proteins. Not my area but if anyone else would care to comment....

"I thought vasodilation can be achieved simply by sustained low-level exercise ?"

But it still is mediated by nitric oxide release

Not my area but....

AFAIK the vasodilation is due to the release in the body from nitroglycerine of nitric oxide ( yes the one from diesel exhausts and indeed many other combustion processes) The nitric oxide, which is also produced naturally by several enzymes from the amino acid arginine, modifies the activity/function of several enzymes/proteins in the endothelium and that's where the vasodilation comes from.

"So diphtheria and yoghurt are close relatives? I always suspected there was something dodgy about yoghurt..."

AFAIK the connection between Corynebacterium & yogurt is indirect. One Corynebacterium species is used in the manufacture of glutamate and then that glutamate is used in various foodstuffs including yogurt.

"One of the most studied species is C. glutamicum, whose name refers to its capacity to produce glutamic acid in aerobic conditions.[27] It is used in the food industry as monosodium glutamate in the production of soy sauce and yogurt."

Re: Opportunistic pathogens

"I don't understand though, why does the immune system get suppressed in spaaaaace?"

Don't have a ready answer to that although I do know all sorts of biological systems seem to be affected by weightlessness + ?. In particular calcium metabolism/mobilization. Calcium levels have a direct and profound effect on lots of systems in the body.

Given the complexity of the immune system and the known effects of various interventions I'd think it might be quite a time before all of the possible effects might be know.

One, rather obvious one, given that sitting on top of a giant firework is in the job description is stress. This is known to have +ve & -ve effects on the immune system.

Don't know what they expected.

Humans can't be clean roomed to the same degree, organisms multiply & filters concentrate. No-one on the ISS ever had a cold, flu or GI upset ?

As an example I worked in a building with forced air ventilation, After Chernobyl, although the local levels of radiation were only transiently raised, the ventilation filters were quite noticeably radioactive having purified many building volumes of outside air every 24hrs.

" suggested we might like to repeat the experiment and test it for ourselves. We're more inclined to test what happens when you pour bromine on, say, a banana wrapped in aluminium foil."

PLEASE DON'T THINK ABOUT TRYING THIS ! Bromine is very nasty, it will diffuse through normal rubber gloves and burns produced by it are dreadful and slow to heal. I knew a chap whose daughter merely put on contaminated gloves and she was scarred for life. I hate to think about the damage that could be caused to eyes.

Can I just have clarification...

about "maximum velocity of a sheep in a vacuum"

I'd assume that given enough energy the speed would be close to lightspeed. Now I do know (living surrounded by them ) that the average sheep is very unlikely to generate that amount of energy on it's own ( for a 40kg sheep at 99% lightspeed I estimate ~2.2E19 J)

Indeed a dripping tap is chaotic

We should really use the phrase 'deterministic chaos' in these cases where, usually, the equations describing the phenomenon can be written but where the extreme sensitivity to initial conditions means that predictions are difficult/impossible.

Best not to use chaos when random is meant.

Re: VOCs

"it's the high VOC stuff that turns yellow, the water based low VOC stuff is much whiter and stays that way. "

In my experience it's the low VOC but non-water based gloss that gives a good finish but yellows rapidly. I'd guess that to make it easy to apply the amount of VOC removed has been replaced with even more of the (necessary) binder which is what yellows.

UV probably works by getting the TiO2 pigment to oxidize the yellowing binder. Water-based, having no need for a large amount of binder stay whiter longer at the expense of poor finish

"but as we've learned the NOx regulations were too strict and not achievable."

Not to minimise this but Eur 6 does seem to be achievable BUT the standard is for a certain mix of simulated driving. As I've mentioned before this will never represent all the possible conditions of actual use.

In any case the actual risk to health is a function of the concentration.time product which can't be garnered from tailpipe emissions directly as it depends on so many factors. ( traffic density & speed , wind & rain, mix of HGVs vs vans vs cars, background levels of NOx from other sources [heating, industry] )

"'ve had lying around for years with the express intention of installing some flavor of Linux, not knowing which one to try. I regularly try out Ubuntu and some others, but they all require that you know Linux to use them (aka mounting hard disks, etc). Nuisance."

Just try out a few live-CDs to see what you like - no need to worry about your HD at this point, but allow for it being quite a lot slower. Once you find something you like then install it - usually just a click on OpenSUSE for example, answer a few questions about location/language and a default install will usually be OK without worrying about mounting or very much else.

NOxious VW emissions scandal: Car maker warned of cheatware YEARS AGO – reports

Chemist
Silver badge

Re: The VW Diesels pass the emissions test

"Agreed. They passed the tests. That much is fact.

Also a fact, they don't emit levels of NOx when driven that match the tests."

The test value can only be a marker of the possible emissions in real driving conditions allowing (if no cheating) some comparison of make/model and some rough prediction of likely effects on short-term air pollution. Given how fuel consumption varies over a large range with such variables as length of journey, stop start driving, high or moderate steady speeds and so on how could it really be anything else.

The 'easy' alternative would be to issue the worst case measurement for any model and that wouldn't reflect real-life use either.

After all take Euro6 - the test value is 80 milligrams of nox /km for cars whereas the environmental limits of nox are concentration measurements so are not directly correlatable - put another way it's some function of other sources of nox + vehicle density & usage pattern ( & wind speed/direction & rain ) for any location

Re: Today VW ...

"run out of urea"

Just to put it in context many (all ?) urea injection systems have a limit to the number of engine starts that can happen after the urea runs out.

For example : "If the tank reaches one gallon, the car notifies the driver. It does so again with only 20 starts remaining. To reset the system, at least two gallons of AdBlue--or four half-gallon bottles, at $7.75 each--must be added. Roadside assistance plans cover AdBlue, however."

Chemist

Re: Alltogether Now

"Urea injection, which only really works during emissions tests too."

Would you like to ref. that. because AFAIK it's simply not true.

Petrol engines also produce less nox than diesel but still a moderate amount.

In my experience diesels use considerably less fuel ( by volume) than petrol engines in similar vehicles partly due to the increased energy content of diesel and partly due to the better thermodynamic efficiency. Indeed large ship diesels are the most efficient internal combustion engines that are available.

Re: Where's the red line?

"The other problem here is that too much credence is applied to the test results."

Indeed. In fact it will be very difficult to have a test that accurately reflects 'real-world' usage as that varies so much.

The extremes might be the city dweller who mostly does short trips in busy conditions with lots of stop/start/idling/acc.

My car might be the other extreme - almost no short journeys, live in the country, travel mostly fast A-roads and motorways at quiet times (overnight), little acc.

I suggest no testing regime will adequately reflect that and that's without considering driving 'style'
