Sy,
Actually I have read that statement many times before about meat being the cause of tumor growth. That could be a totally false premise based on anecdotal evidence as is often the case. What would be more interesting would be an actual controlled study of those who eat no meat vs those who consume a controlled amount of animal protein and the instances of certain cancers. Now when the subject just so happens to smoke on the sly or actually consumes far more of something that the test participant acknowledges then we get these false results. You know how well people are about telling the truth to researchers, such saints are these people!


That's exactly what I meant about poor controls- a real problem when dealing with humans. In the work I was doing in Texas, we had no problem inducing cancer cell proliferation with phytoestrogen exposure (e.g., some of the natural constituents of soybeans).

REALLY? That's interesting... Did this include eating the entire soy product, or isolated phytoestrogen? What carrier?

I have to ask because...

The phytoestrogen in soy is such a weak one that it rarely can trigger an estrogen response on a cell that it will bind to. Where as soy itself seems to have a varied response to humans.

*I had a roommate in college. If he consumed soy products he'd turn pasty and sweaty, and have to take a nap. This is just anecdote, not formal contribution.

*There are some people that must have a mutation that makes them hypersensitive to phytoestrogens that cause no response in others.
 
Totally agree Sy,
I read so much telling you to consume more soybean protein and then you see this anecdotal evidence that points to hormonal changes in males from the consumption of soy protein.

On a totally different subject this is what drives me nuts every day. I just received an offer for a contract job position and this is the description of the job. Now can anyone actually tell me what you would be doing besides the industry and it involves plastic molding? Drives me nuts to say the least, do the hiring managers go to a special class in how to obscure a function, sometimes I have no idea what they are doing after reading an entire page telling how great the company is or how they treat their employees. Could be designing a housing or could be a catheter or an implanted plastic hip joint, who knows. I guess all plastics are the same and all processes are something any mechanical engineer should know!

RNM,
I'll assume for now you are sighting some testing done with Rats, not always relevant but the best we can do without using human subjects.

Contrary to SY's natural knee-jerk bashing..... yes it was rats and it was a serious journal/researched. It was not a very complex question --- does animal or vegetable proteins have same/different or ?? on cancer tumor growth and if so at what protein levels of each. No amount of plant protein caused the tumor to grow.

Now you can argue the amount of animal derived protein if you think you have a better study with better numbers. But animal protein did cause cancer tumor to grow.


A rather significant finding. BUT IMO they did not control the animal protein well enough.... For example, had the animal ever been injected with anti-biotics, growth hormones and the like. Or was the meat from natural feed which its self was not contaminated with insecticides or un-pure water used?

That is, it may not be the protein in animals but what they were also feed or injected that gets into the meat in some form. But, having said that, it is common practice in USA to inject and feed all manner of unnatural things to the animals and that is what we are actually eating, anyway. And we eat a lot of meat/products in our culture.


BTW -- If you eat little or no animal derived foods (eggs, milk etc) then you might get deficient in essential B12 and supplementation would be in order. tests will tell you.

However a bit of search engine activity does provide some material about bass gain in small rooms and vehicles.

Pressure mode. Large cone area or large excursion in a small enclosed volume. Modulates atmospheric pressure! Wave issues don't really come up. That is where your PITA is confusicated. (Word I learned from a sort of English speaking graduate student.)

I had a really bad time with the wave mode in an domed arena. Everything all set and working but no LF. Checked all the signal levels no luck. So I started lowering the cluster and ZAP!, the bass kicked in. Very educational example of loudspeaker placement and wave cancellation.
 
Speaking about sugar and food...how about those beeswax filled fuses with heavily gold plated caps? An incredible marketing strategy, focused on the truly gullible. A real tour de force; took a lot of balls, and no conscience, to pull it off.

Actually meaning to get some measurements. I suspect the current required to blow the fuse is increased as is the thermal mass. Might actually make a difference in a loudspeaker line fuse. Even for a power supply fuse in a dreadfully designed piece of gear.

Of course the biggest advantage is the flame and smoke will indicate when you blow the fuse.
 
Henry,
Is that locally sources bees wax, I wouldn't want that East Coast wax in my California power supply. 🙄

On a more audio related subject I have a question about using an ADAU1701 and a TI TPA3251D class-d chip. Would you place a balanced line driver between those two, the TPA seems to appreciate a balanced line drive on the input. I can't discern if the ADAU is balanced output or se, I have a feeling the analog outputs are single ended. I was looking at the THAT 1606 to take care of this if necessary.
 
Totally agree Sy,

Anecdotal, yes. I've never witnessed anyone consuming soy and having hormonal changes except one guy on the internet who's hyper sensitive. Probably for the reason I stated.

There's more evidence that polyunsaturated fats are dragging down the male hormones, than soy.

Just saying... the super girly weird guy that goes to a health food store and buys tofu, was probably the same guy before he tried tofu.

Technically the phyoestrogen is such low quality it can displace real estrogen made by the male body, which would make the male produce more testosterone since mechanism for triggering testosterone production is based on the amount of estrogen that triggers receptors on the brain. (the body produces both at the same time) However one's hormones would be all wrong say if their body processed soy poorly and the liver was functioning at a sub-par state. How? Soy has some very strong antioxident properties, perhaps too strong for some people. It's probably a more important factor that a person may be displacing other nutrients their body works particularly well with, with soy.

I have a friend who is convinced that he must be a vegetarian in order to avoid colon cancer, which killed his father and afflicted his brother (who however survived). I didn't have the desire to ask him how he had determined that a meatless diet would lessen his chances of contraction.

Another guy (the selfsame PhD in musicology) has such a strong belief system erected around cholesterol and blood pressure that he once lamented that he'd forgotten to bring his meds with him on a brief visit. For a while I would send him dissenting views on the wisdom of medicating against these conditions, but he made it clear that he preferred not to be confused by such views. Meanwhile his family has a history of dementia, and he may even be aware of some correlations alleged to be associated with statin drugs. For him it's obvious that little demons are busily plastering his arteries with gunk and he's combating this with Lipitor.

Tragically, for a job like that you'd get about $45k on a good day. Now, if you can sell PVC windows, you get double or triple that. And that my friends is why there's an engineering shortage in the UK. Engineers are treated like absolute **** for the most part.
 
bcarso,
I have friend who is younger than I am, took terrible care of his diet for most of his life and paid the price with four stints in his heart due to blocked arteries. They put him on statin drugs and he completely changed his diet, got the word about losing lots of weight and got to exercising. His cholesterol came down to normal, all his vitals are now normal and he has lost most of the weight. I talked to him a couple of months ago and he had just come out of the hospital, the statins almost killed him, doctor took him off all his meds, told him to just keep watching the diet and doing the exercises, the drugs almost took him out.
 
Bonsai,
The job is in the Bay Area, Silicon Valley so you don't even look at those jobs for under $80K or your going to starve just due to the cost of living. I won't even tell you about the one that got away, I screwed up, I'll leave it at that. Would have been six figures and I could work from home, I will always remember that mistake! I lost another one in aerospace because I asked for $1 more per hour, glad I didn't get that one.
 
To indulge the diet connection some more at risk of veering off topic (laughing out loud at that last one!), I'm fortunate in never caring that much for sugar, regardless of the form, occasional sticky wines excepted, although I won't reject a dessert served me at the end of meals at friends' homes. Coffee is drunk black. I don't drink sodas whether sugary or artificially sweetened. I don't eat fast food and I don't eat a lot of prepackaged foods. I eat lots of low-carb vegetables, pastured meats and fowl, occasional line-caught fish like salmon. Simple carbs like rice, potatoes, pasta are treated as infrequent delicacies. I salt to taste.

My downfall is fine wine. When I get too tubby all I need do is cut out the wine and my excess weight goes down precipitously. If I go for long brisk walks daily it falls further. The last time I did this I got so skinny that people were advising me not to lose any more weight, and more were quietly averring that I was deathly ill and unwilling to admit it. Nope, not yet anyway.
