Bourke
[edit]You have shown an interest in the Bourke engine in the past. This engine's page is presently undergoing peer review, it would be appreciated if you would review this page and give any comments or suggestions you may have. Bourke review page. Thank you very much for your time and help.Sno2 16:09, 27 May 2007 (UTC)
Efficiency
[edit]I question some of the things in the engineering critique concerning efficiency....believe you are insinuating that the losses are bigger then they actually are...
looking at the thermal efficiency only...
Assume both the bourke and conventional burn the same amount of fuel and the final temperatures are the same to begin with, say 2000 degrees.
Assume thermal loss through the cylinder walls are the same.
Both engines running under the same load.
Measured: Bourke exaust temperature around 200 degrees Conventional around 800 degrees
2000 - 200 = 1800 amount of fuel energy equal to 1800 degrees is used, either in load or in internal losses.
2000 - 800 = 1200 amount of fuel energy equal to 1200 degrees is used, either in load or in internal losses.
The difference is about 30 percent.
I do not think the losses you refer to your engineering analysis would lower the final efficiency of the Bourke by more then 5 percent....in fact think it would be probably be around 1 or 2 percent.
Note: Am giving all the advantage to the conventional...Bourke temperature initially hotter for same amount of fuel...average temperature of cylinder lower in bourke then conventional, less thermal loss through walls.
Does this make sense...and if not why not...??Sno2 21:07, 28 May 2007 (UTC)
Scientifically Proven/Disproven or Unknown
[edit]Below is based on NICE CFS/ME; full guidelines (06Sep2K7) , which is based on literature searches and consultation with experts. The NICE document appears to be the best review avalable at this time.
Definitions
Hypothesis: Guess as to why or how something occurs, not proven by enough experiments.
Theory: Hypothesis that is assumed to be true, based on enough experiments, that is commonly accepted by the scientific community to be true.
Theories:
- 1. CFS is a seperate disease from other diseases.
- 2. Stress both physical (heavy exercise) and/or mental are a triggers that can increase symptoms.
- 3. BET (a form of extremly light exercise) can lessen symptoms in some people.
- 4. Cognitive therapy (type of talk therapy) can decrease symptoms in some people.
- 5. Some practices can reduce symptoms in some people (yoga, tia chi, etc).
Hypothesis:
- 1. CFS is or is not a viral disease.
- 2. That there is a known cure.
- 3. Alternate therapies (ex: vitamins/herbs, etc) can decrease symptoms.
