Sorry, that slogan is already taken by Conglomo.

Have you tried kefir? Many folks have had success, in fact Dom's Kefir in-site has a bit more in this as well. Yoghurt is technically pro-biotic, but it's effects are only temporary while Kefir can actually repopulate the mucosal lining of your GI tract with beneficial bacteria (which people often mistake yoghurt with doing) and many people have found kefir to help them in sundry ways. The only problem is that almost all store bought kefir is not made from scratch and therefore not nearly as potent as the home-made stuff. Give it a try, it couldn't hurt!

But explain to me the significance of daylight savings time. I mean really.

In the pre-electricity "modern" era, families that stayed up after dark would light their homes with candles and oil lamps, which could get quite expensive ... The idea was proposed by Benjamin Franklin (known for his strong work ethic), that if the clocks were moved earlier towards the dawn in the summer, then there would be plenty of daylight in the evening after work, and thus countless candles and barrels of oil could be saved.

Extrapolating that to today, there is still a chronological swing to the usage of energy... in the bulk power industry, this is called a "load curve", and basically follows a sine wave... there's a valley in usage over the early morning period when everyone is asleep, and as people wake up, the load increases in the "morning ramp", reaches its peak in the afternoon, and drops off in the late evening as people head to sleep.

Now, moving the clocks to line up with the daylight periods would shift the energy usage one hour earlier in the day. In the morning in the summer, the sun is already up, so you're not going to save much electricity. However, by shifting the evening clocks forward, it removes some of the "lighting" time in the evening, which lowers load on the system, allows the generators that match load to drop their output lower earlier, they burn less fuel, and the economy as a whole saves money on imported fuel.

Actually Good Friday falls on March 30 in 2029. Unless you happen to be on the Orthodox calander, in which case it falls on April 6.

"Gala" is as in festival. "Galah" is the pink-and-grey avian clown.

Alston would be more of a chook - clueless and not particularly pretty. (-:

I'm not sure what you're trying to say, but the JN-4 Jenny was a primary trainer, not a military combat aircraft. Why don't we go on to say that the Germans had Me-262s while our boys had to fight with PT-22s?

The Vickers Vimy is a good example of a World War 1 vintage bomber.

Very little in the time period of World War 1 was internally braced or inclosed.

I honestly thought that the supersonic jet would be the savior of this company.

Their supersonic airliner project (the 2707) was canceled more than 30 years ago. I don't think that has any bearing on how Boeing is doing today.

(Read more about the Boeing 2707 here.)

What about the Lifting Body (LB)? It should be included with the wing and rotor(which are really just rotating wings).
The Space Shuttle is an LB, the wings are not really wings but they look like wings.
The Six Million Dollar Man plane that crashes during the first part of the show was a proto-type LB plane.
The new International Space Station/Alpha will use an LB emergency escape vehicle.
A lot of new high performance aircraft will use it too.

NASA info on LB
Very nice collection of pictures page is in Japanese .
an interesting study

The SPL is the sensitivity of the speaker. Because dB are logarithmic, a +3 dB change represents twice as much sound output. The SPL is a measure of how much sound output there is per watt.

My argument about the resistance (Ohms) doesn't hold water though because when you change the power (watts), not the current or voltage, it reflects the change in resistance. The equation is Power = Current^2 * Resistance. As far as the amp is concerned, though, if it it can handle more current putting a 4 Ohm speaker rather than an 8 Ohm on it will effectively double the volume coming out of the speaker at the same level on the dial. Oh well, I guess I shouldn't post when I'm tired!

Anyways, back to the meat of the matter. Because the 93 dB speakers are 4 dB more sensitive than the 89 dB speakers you'd get more sound out of them than the 89 dB speakers (if they were 50 Watts to begin with -- at 25 Watts I'm wrong. Oh well).

Basically SPL is a measure of efficiency of the speaker. Sorta like Gas mileage. Higher is better (but watch that the distortion rating is OK).

There's more info here.

I have a screwed up ad from Radio Shack displaying a 50 watt subwoofer @ 116 dB sensitivity for $199. I seriously doubt that anyone would tolerate a subwoofer that loud in their home, nevermind that at that price it isn't possible (yet).
