"GM-related"? My goodness. Well, so is dirt and water, in that sense.

It illuminates the approvals process, which appears not to work in the public interest while giving the superficial appearance that it does.

OK, so your objections are political, not scientific.

Point source (1 driver) has the spherical wavefront, with power falling off as 1/R squared. A line array drops off as 1/R, and nearfield planar does not fall off.

The choice alters the head positioning sensitivity to the sweetspot. In all my calculations, I use point source.

Demian,

When you get a chance, can you do the capacitance?

If it runs 50 pf per foot, it's probably coaxial with PVC or some related plastic.

If it's 65pf per foot, it's most likely three twisted pairs with orthogonal pitch, pvc likely.

If it's 25 pf per foot, it's a foamed coax core, probably a triaxial geometry like what I posted about 5 years ago.

If it's foamed triax, I'm not sure it would pass UL listing as portable cordage.

If it's flat conductor, I'd think about 50 pf/foot.

Thats not fun or funny.
I've never heard about the white blood cell count going up. Was that published?

Hemp has a direct effect on consciousness. I stay away from it for the past 43 years.

What are you talking about? It's got two HUGE side effects.

1. It gets you high
2. It gives you the munchies

And if it weren't for the first side effect, there wouldn't be nearly so many people asking their doctors for prescriptions for it.

Hi Richard,
Being a vegetarian for the past 43 years, I took for many years vitamin B12 and Vegetarian Omega 3 food supplements. Since in my country there are almost no GE vegetables and since I eat a lot of vegetables and fruits, I didn't need any other food supplements.
Now I'm 69 years old. On recent years I added multi-vitamins and some other food supplements, mainly for my back aches and some memory deficiency.

In the light of the present situation of GE food in the USA, it seems to me that food supplements are recommended for all people. To my view, organic food is much better, with or without food supplements.

I could afford consuming mainly organic food only on recent years, after my retirement. When I worked, I either ate at restaurants, or catering, so I didn't have the option of choosing organic food.

It is a very sad story in the USA, since many top employees of the FDA are former employees of a well known chemicals corporate which is also known for GE vegetables. They managed to make the FDA declare that GE vegetables are no different from non-GE ones, hence it is forbidden by USA laws to state that certain food is GE. In some states it is forbidden by law to publish any criticism on food suppliers. Perhaps conscientious people in the USA would better raise their voices, for the food situation is really gloom.

Genetically Engineering is in a way playing God role, none knows definitely what it does and what are the effects and consequences on the long run.

Meanwhile, purchasing mainly from farmers markets may be a good choice.

I'm sure that anyone who will watch documentaries about how animals for food are reared in the USA will stop consuming any meat. As for myself, I'm a vegetarian out of compassion to all living things, including animals. Only on recent years I became aware of the great benefit to health it is.

Any check on the internet will tell you we typical Americans consume 80% GMO foods.
But not allowed in Europe and Japan and other countries as unsafe/unhealthy.

Thx, RNM
It is so because of in the USA chemicals and food corporate managed to twist the arms of the FDA and other government bodies.

It will remain this way until enough conscientious people will raise their voice load enough.
