No, it's just the non-relativistic version. There is another component to the equation that for small enough values of c', that extra part kind of washes out. As c' approaches c, the apparant mass of the object also increases, and the energy required to go faster starts to approach infinity (think giant particle accelerators all to get another decimal place amount of c'/c (i.e.,. from.9998 c to.99998 c for electrons/positrons).
AFter watching some of the crashes in the downhill, having some of this stuff on your hips, shoulders and lower back probably would be helpful. Slamming onto the ground at speed (50-60-70 mph) has got to hurt whatever hits the ground first. The downhillers are racing on some pretty icy snow, not soft fluffy powder. Also, on your pointy spots, (hips, shoulders), you might also want something ablative...
For GS and Slalom, if you suck at knocking poles away, it might be nice to have on your hips and shoulders, too.
Monkeys were being stored in a business park in Reston, Virginia, prior to going to their final destinations. Reston is a suburb of Washington, D.C....
And probably the main bacterial vaccine that everyone should be familiar with on Slashdot, tetanus toxoid vaccine. There are quite a few more antibacterial vaccines for animals (campyolobacteria, chlamydia, etc.).
Avian flu is known to have killed under 100 people worldwide, since 1996. Worldwide deaths from normal influenza currently reach 500,000 EVERY SINGLE YEAR worldwide. FIVE MILLION PEOPLE since 1996....but who normally dies from "normal" influenza? Aged and young children or people with weak immune systems. It has the potential to kill a "normal, healthy individual", but how often does that happen? Not nearly as frequently.
Avian flu has the potential to reach out and zap everyone, which is why it's a big deal.
The thing that is overhyped however, is the "it will kill us all!"
No, if an outbreak started in Kinshasha instead of in the jungle, the possibilities of rapid viral doom greatly increase. For one, Kinshasha is a big enough city with various modes of travel out of the city, and enough people "flux". As it stands, since it happens first in the boondocks, it's easy enough for it to be isolated relatively quickly once the alarm gets out.
Plus, it's so dang lethal in a short time frame. Flu is successful (even the flu of 1917) becaues it took a week or so for you to die if you were going to die. Plenty of time for you to cough and snort over your environment, ensuring others got sick.
Ebola tends to get transmitted in the Congo because of human-human contact. Person gets ebola, gets sick, people tending him get his blood on them, they get it ebola. But in a small village, there is likely to be one smart person who observes, "if everyone else taking care of the sick people also gets sick, I'd probably be better off isolating myself", so the disease eventually burns itself out.
If you think of it like a fire, ebola is a rapid oxidizer that, when it comes in contact with its fuel (humans), produces a hot fire that burns out too quickly before it can turn into a raging inferno. Now this could change rather quickly if it mutates to become airborne or takes slightly longer for it to become symptomatic, both giving it more opportunity to spread itself before people modify tthings to slow it down or stop it.
It's a thing of the past in "rich western countries" because we've drained off most/all of the swamps, most of them have temperate, not tropical, climates, and the mosquitoes that harbor it don't do well outside of the tropics or were beaten back while DDT was still being used, and have been outcompeted by other mosquito species. That notwithstanding, the incidences of Dengue Fever, for example, are slowly creeping up in Florida... then there's west nile virus, equine encephalitis, etc... Bug people were suprised to find so-called "tiger mosquitoes" doing well on the left coast of the US (they are bigger and more agressive than native N.American mosquitoes), but only speculation for how they got over here from Asia.
Well, lucky for humanity, it seems to be too lethal, but it does mutate quickly. A slightly less lethal version that had a slightly longer shelf-life could cause lots more problems.
Which is all the reason why there is such a hubbub about SARS and bird flu. Some of it is panic mongering. Some of it is plain and simple "the potential of this to do bad shit on a wide scale in a short time is worth scaring people and developing a vaccine quickly".
Are we worried about the people who actually live in the Congo jungle? Not that much. It's there, it'll always be there. It just is not in anyone's interest, though, for someone who is presymptomatic to hop on a jet that is going to Cairo, for example, without having SOME sort of backup plan besides isolation. It's easy enough to isolate the small villages, etc., in the Congo region. It will not be possible to do so in a place like Cairo. You'd have to lock down the entire city and its 20 million inhabitants.
Well, if their exposure to the virus in the wild is far greater there than in Europe, US, whatever, then it makes more sense to do it there, too, even at the risk of "exploiting" the natives. If it's going to work as a preventative, then it needs to work in the hot zones, so to speak, otherwise it's not really going to work.
We have no problem testing new cancer treatments that are on the verge of lethal for "normal" people on terminal cancer patients...why is this any different, then?
If I think I've developed a new treatment or prevention of cholera or typhoid, I'm not testing it in Anchorage, AK. I'm going to Manila, Buenos Aires, Rio de Janiero, Cairo, etc. to see if it actually works, once I'm pretty sure that the drug won't kill those it is put into outright. I can't just sneak into a water treatment center and surreptitiously route sewage discharge into the drinking water supply bypassing the filters and Cl2 treatments, etc.
Thalidomide works on the bacteria that causes Leprosy. Should it not be used for this because it also causes gross birth defects? Just don't give it to pregnant lepers, then, duh.
No, it would have been the other way around. This was simply a test to see if the vaccine does NOT evoke the thing it is trying to prevent (Ebola) or cause any other outright acute adverse events. Eventually there will be inocculation with the vaccine followed by exposure to Ebola virus (or enough of the virus to see if an immunologic response is evoked while minimizing the risk of actually getting Ebola).
Well, if you've read "The Hot Zone", there are at least two different strains of Ebola. Actually, each outbreak of Ebola seems to be a little bit different. The strain that came into the US is now called the "Reston" strain. Luckily it only caused bad flu-like symptoms in the two people who got it from the monkeys that were in that Reston, VA, business park, and it didn't turn into the full meltdown version that usually happens in Africa.
What is even more interesting about Ebola is that Ebola antibodies are found in new world as well as old world monkeys, but the only outbreaks seem to be in Africa (Congo jungle)...
"The Hot Zone" is a pretty good book. If you want more details on tropical illnesses, read "The Coming Plague".
If we allow the state to sweep away the normal walls of privacy that protect the details of our lives, we will consign ourselves psychologically to living in a fishbowl. Even if we suffered no other specific harm as a result, that alone would profoundly change how we feel. Anyone who has lived in a totalitarian society can attest that what often felt most oppressive was precisely the lack of privacy.
Well, moving into a small town or other community that has not had a lot of population turnover is the same way. Everyone knows everyone else's business. If you aren't used to that, or just happen to not engage the folk of the town, speculation at some point turns into "fact" (perception == reality), and the next thing you know, you're defending yourself, either in the social forum, or, more bizarrely, in a criminal forum, all because you're Not From Araound Haeah.
Funny, all the apartment complexes that I've seen that need/want to provide some sort of window dressing for "security" hire companies to provide it for them, not the cops.
Sounds like there are some inherent problems "repeat calls" in the areas in question, but the chief doesn't want to/can't do anything about it. No investigation into root cause. A couple of mentally ill individuals in a tenement...er, apartment complex? OK, call Social Services, do something to help them (help them take their meds, move them to a better environment, etc). Instead, it's a lazy-ass externalization of the problem with a simplistic "fix" that is designed to fail while at the same time allowing those involved to say "we're doing something about it". Apartment owners (if it's private and not government) don't want to put the bucks into it, either, as it cuts into their profits.
Has anyone ever done something to your car or your property while you were sleeping?...and how many others have met indifference, at best, or downright derision, when they bring these things up to the police?
"Really, someone stole the $10.85 from my coin jar while I was at the laundromat. I think I know who did it, why won't you do anything about it?"
In some ways, first-world farmers are efficient (or at least, productive). The production outputs by one farmer these days is pretty amazing, compared to even 30 years ago. But it sucks up a LOT of energy resources. There is a swing in some areas to methods that take fewer inputs, yet receive the same or nearly the same production outputs that "traditional" methods use. No-till seed drilling, dual-cropping, etc are some of the ways to it.
For those who question it, have you ever seen pictures from when wheat was harvested with horse-drawn equipment? Lessee... 40-horse team was not uncommon, a crew to run the steam engine and thresher, where to put the mountain of straw? Lots of work for teenage boys stacking sacks of grain. It used to be a MAJOR endeavor. Now 4 or 5 combine drivers, a couple of tractors to pull grain wagons around, and a couple of trucks to take grain to the driers or silos, and 1000 acres/day harvested is not impossible.
Where I live (Willamette Valley, OR) is the major rye and fescue grass seed production areas in the US. Some of the methods people use require LOTS of work, yet my neighbor, who is big into no-till, does just fine with his no-till drill (he does a lot of custom no-till planting, too), plus doesn't spend a lot of time in the fall and spring removing cover crop or stubble, prepping the soil (plowing, discing, pulverizing, smoothing), etc. His no-till drill just sticks the seed right in. Sure, no-till is not for every crop, but it works well for grass.
He doesn't have a lot of bare fields this year, which is kind of luck of the draw given the rains here this winter. But other farmers, who have hundreds of acres of bare or fall-planted fields right now where the seed is just now starting to germinate (and don't do no-till), have suffered some pretty significant soil erosion this winter. Kind of sad, realizing all the topsoil that has been washed into the rivers. Plus, there is all the topsoil they convert into dust in the summer and fall, too.
Dairy farms are more and more starting to either make biogas generators (i.e., covering up the manure pits and piping the gas into compressors and burning it in generators. Makes sense if you've ever driven past an open manure pit on a hot summer day) or other equipment that rapidly breaks down the manure into water and solid products. But this equipment costs some pretty good coin.
yes, some of these equipment installations are because of environmental concerns of either waste water leaking into groundwater supplies or air quality concerns, but still... some of this is being done.
the average feedlot, however, probably is not into this as much. If you have enough manure volume, yes, there is a smallish side market of processing the manure pile into mulch or compost, but that's about it. Except for some special product areas (zoo poop, pelletized poultry waste), it's pretty low margin, so you need a lot of manure to make a go of it. it's pretty seasonal, too. Some environmental concerns are driving this kind of equipmentop,l for other livestock production as well (poultry, pork).
Me and my 30 or so sheep? Well, the sheep poop is good for the pasture. As long as I'm not taking the sheep off and putting them in someone's freeezers, it is a relatively closed loop as far as my pastures go (I don't need to fertilize a lot!).
Sell it to whom? GameCrazy, EB or other store that buys used platform hardware for resale? I'd probably get, what...$10.00 for my PS/2? Sorry. It's paid for, it's depreciated, it's salvage value right now is about $0.00.
Censorship is slightly evil, but not as evil as Yahoo throwing people under the bus, as it has done at least twice, providing information leading to Chinese authorities leading to the arrest and confinement of dissidents.
Google's "censorship" has workarounds. Chinese gulags don't.
Well, they did have those two tethered satellite experiments that they ran on the Space Shuttle, and even in LEO with a relatively short tether the potentials between the satellite and the shuttle were pretty big.
What exactly is the mass of the earth compared to the total mass of the space elevator? I think the term, "negligible", comes into play here. The moon and resulting friction from tidal motion of the oceans has far more impact on the earth's rotational speed in one day than the space elevator ever will.
Where is the islamic world's condemnation of the Albanians that were killed in Bosnia-Herzegovinia, Serbia and Croatia? Nowhere.
Where is the islamic world's condemnation of Syria manipulating the affairs of Lebanon? Nowhere.
The goal of most governments in Islamic states is to maintain a sense of unbalance within their populations, to keep the focus of the ills of the populations on the Western Infidel governments, etc.
Only in Lebanon do we have a sense that SOME people in the Islamic world have a clue, that their so-called Islamic bretheren governing them are as evil and corrupt as anyone else, and that some OTHER external power besides Israel, GB or the US is screwing around with them, and that they've had enough of it.
Didn't hear too much acclaim from all the other Islamic governments praising the Lebanese for rising up against the Syrians, did we? Nope.
