Just Chat! / Why does no one ever thank me any more

« on: 21/12/2018 20:42:33 »

Browsing thru some posts from 2007 I noticed that I had been thanked 44 times, 11 years later my total is still 44 I know my mental powers have declined as I get older but as I seemed to be well received until 2007 why did my comments and answer to questions suddenly become unworthy of any thanks comments.

Two bombs where dropped in rapid succession two convince the Russians that the USA had a plentiful supply of them, Stalin was not impressed he had better sources of information.

Physiology & Medicine / Re: Why Are Piggys Organs Like Human Organs ?

« on: 29/07/2018 17:12:45 »

The greatest danger to anyone with a failing heart that can only be treated with a transplant is that they will die before one becomes available.
Would it not be humane to allow people who have little or no chance of obtaining an human transplant that well may have dangerous viruses to have a pig one to see how real the problem is.
The chief concern seems to be that Porcine viruses could become endemic in the human sperm line but as yet there seems to be little evidence that this would happen from people who have received heart valves etc.
"A clinical trial study performed in 1999 sampled 160 patients who were treated with different living pig tissues and observed no evidence of a persistent PERV infection in 97% of the patients for whom a sufficient amount of DNA was available to PCR for amplification of PERV sequences. This study stated that retrospective studies are limited to find the true incidence of infection or associated clinical symptoms, however. It suggested using closely monitored prospective trials, which would provide a more complete and detailed evaluation of the possible cross-species PERV transmission and a comparison of the PERV "
This risk could be eliminated by sterilising recipients so that they cannot breed a small price to pay in return for the extra life a transport would bring.

Albert Einstein and a collaborator took out patents on a magnetic refrigerator.
I am in error here it was an adsorbtion type refrigerator with a magnetic commpressor

« on: 09/02/2018 17:24:19 »

I think that whether or not it can be proved that they can perceive pain any animals that we eat should be killed first as if they can the problem arises with oysters that are normally eaten alive .

« on: 09/02/2018 17:16:32 »

Back in the days when Wimshurst machines and electrostatics were all the rage I think they used to melt something like pitch and induce a charge into it that it retained when it solidified.

« on: 07/02/2018 21:10:02 »

I think that any BH would have to have a mass of greater than the Plank mass to survive and that requires vastly greater energy LNC has.

I am old enough to remember pre war prices when we got 5 us dollars to the pound compared to the amount of hours worked to provide it some things like houses have become much more expensive while technical things like cars, phone calls , and communications. are cheaper (you could buy a house for the cost of an hours phone call to the USA or a large TV).

« on: 19/12/2017 17:25:48 »

Speed is of course a vector quantity but due to the geometry of the aircraft your speed can only add or subtract from the speed of the aircraft relative to the ground excluding SR.
If you were in a large saucer shaped alien UFO and could run in any direction the angle relative to the craft would have to be taken into account.
Warning do not try this on a Ryanair trip !

You can never fail to save on electricity if you shut off something that is not needed but beware the ambient temperature is seldom low enough for the long term storage of frozen food.

« on: 10/10/2017 19:51:16 »

The only danger warning I have seen on a mobile phone transmitter tower was in Germany which said don't stand too close in winter as large icicles fall off. I understand in the USA 6500 deaths a year result from people driving, walking etc. while using them that's where the danger lies

When I was in the printing trade 30 years ago all the film processors were equipped with electrolytic units to salvage the silver I don't recall there ever being any mishaps.
Google list many manufactures of recovery units
