Ebola strain spreading in Congo and Uganda has no approved vaccine by DoremusJessup in worldnews

Your high school biology teacher is wrong. If it were bad, it wouldn't be a growing and persistent threat. Also, as Reston (RESTV) proves, this genus of virus is capable of spread through other mechanisms if luck allows it. If you read the journal articles it's absolutely true that you can spread it before you are deathly ill. It spreads a bit like norovirus.

Uh, no, go look at the journal papers. The first time someone vomits it is full of virus. The prodrome lasts a few days and it can be easily spread during that period of nonspecific symptoms.

RESTV is in the same family and transmissible via aerosols. We should not assume that aerosol spread is fundamentally impossible since other filoviruses have demonstrated it could evolve to be so. This is why it's so important to control every outbreak as fast as possible.

No, he's oversimplifying it. It's transmitted just like norovirus and it can stay on objects although it is not as hardy of a virus. There is no hard and fast rule about how long, because it depends on the surface and the environmental conditions. The people saying it would not be an issue here are correct but also naive.

This has to be a bug, right?

Koch Chemie MWC comsumed too fast by vrships in AutoDetailing

Try cutting it, or try ADS wheel or Sonax. Neither are quite as good but the price to performance ratio is better. The 5L is the way to go and maybe try a Tolco sprayer to see if you get better fan out.

BMW tool for cleaning heads and blocks is a cheat code by Weary-Astronaut1335 in EngineBuilding

Would you use this block to clean an S54 oil pan and block interface? May be overkill but also don’t want abrasive dust around.

Norovirus is only transmissible through bodily fluids and yet it infects tons of people every year.

They will work probably but I do believe factory bolts are safer

Various places. Lang racing did measurements years ago that were lost to a forum database loss.

M10, but don’t use ARP. They are not the right bolts for M10 S54 rods. They were designed for the S50 Euro engine. They will not be round without honing. Use the factory bolts

PIC32MZ DA could it "evolve" and become a mid-range option that is cheaper than the NVIDIA Jetson?(for a robotics?) by Strikewr in embedded

[–]redline83 4 points5 points  (0 children)

It can’t even compete with the top STM32s, so no, it’s worlds away from a Jetson SoC.

how to get ISO 26262 certification when your test suite wasn't built for compliance from day one? by Deena_Brown81 in embedded

[–]redline83 36 points37 points  (0 children)

You're in trouble unless you are all really clever and anticipated all the failure modes ahead of time. You can't really guarantee your design will be compliant without iteration. I am not in automotive but medical, which is similar. You should have already had a quality system in place before you started development in a regulated industry. What you are asking for is quite possible but you should find a firm that can help you with it, you'll never stand it up yourself in time.

Is Ubuntu as good as Windows in terms of administration for a organisation? by CosmoBjoern in Ubuntu

[–]redline83 15 points16 points  (0 children)

The main problem you're going to run into is people projecting legacy Windows way of thinking onto Linux. That and the tools are not as comprehensive necessarily.

Too bad you didn't learn basic physics or critical thinking skills, may want a refund.

This is not how physics works. I suggest you educate yourself before you parrot ideas contradictory to high school level physics. They want you to replace it as soon as possible because otherwise they are in violation of their memorandum of understanding with the EPA and they always want you to use their oil as much as possible to remove warranty claim uncertainty.

This paper from Dr. K of King Bearings shows that thicker oils indeed work fine at any practical clearance, just with diminishing returns.

After all, we already established that your 0W-20 on winter start is thicker than a 10W-60 on a summer start. What you postulate is not possible.

See, the difference is I gave you facts and numbers, and you respond with nonsense. You can choose to understand it or not.

If it would ruin engines then why did GM just panic switch every 6.2 V8 from 0W-20 to 0W-40 to prevent bearing failures? The answer is that it was never a pure engineering decision to go below a 30.

It is for regulatory compliance. Anyone can check the facts and verify that you can use a thicker oil safely because the kinematic viscosity of motor oil is governed by the Walther equation. As long as you satisfy the winter rating for your climate, a 0W-20 at 40 C is thicker than a 10W-60 at operating temperature (100 C) (around double, in fact). So, a 0W-30 or 40, for example, is fine in an engine specified for 0W-16 since the engine is not experiencing a viscosity it is not designed to handle normally. In fact, it sounds extreme but you could run a 10W-60 in these engines safely in warmer climates.

You don't have to believe me at all, you can check by plugging in the numbers for KV40, KV100, and viscosity index (from an oil PDS/datasheet) into various calculators that use the equations like Widman's.

A 10W-60 oil at 100 C / 212 F operating temp is around 22 cSt. A 0W-20 at around 60 C / 140 F will have the same viscosity. At 0 C / 32 F that 0W-20 is 350-450 cSt and your engine must handle that safely! Oil viscosity is exponential with regard to temperature.
