Um emergency lighting. Many public places are required to have emergency lighting that is able to continue to give out sufficient light for people to exit the buiding after power has been cut. Currently these lights use separate self-contained units with a lead acid battery and low voltage bulbs. This is a bit simpler and quicker to install, just change the fluorescence tubes.
The reason sugar has such a volatile price is due to protectionist agricultural policies that distort international agricultural prices and skew the normal balance of supply and demand. High fructose corn syrup is a protected industry within the US, and so has a pretty much predetermined price.
Strip away the protection and Corn syrup would have just as volatile a price as sugar.
You totally pulled that stuff out of your arse. Diesel and LPG are popular because of the reasons you have mentioned. But there really hasn't been a chance for anybody to transition a taxi fleet to hybrids mainly because the first hybrids were small cars and unsuitable for taxi service. Now you actually have to come up with some data that shows the prius wears out the battery that quickly, and that the battery is priced so high that that it negates the fuel saving. Using your very dodgy worsed case math a taxi hybrid would need a new battery each 80K on average. Prius batteries were originally priced at $4000 to install but have been steadily going down in price, at that kind of cost a hybrid taxi would still be cost effective. Also the environment a new york taxi is in is the one where you will see the largest difference in fuel economy between a hybrid and a conventional engine.
You are right, BCC's do not usually spread and are not usally fatal, but they also do not stop growing. Left untreated they can do significant damage to nearby structures, like cave in the nose or something or simply effect a large area of skin. If the cancer gets to that point it can still be cut out, but the damage and scarring will be very large compared to the minor scar that will be left if it is cut out early.
I dislike the word "truth" associated with religious belief. Religious texts are no more truth than any other literary work. It is a third source at the absolute best, and more likely some thing more likely a 50th source for any established religion. It is absolute chinese whispers bullshit even if it actually orginated from some original "creator". Most likely it was invented by a group of people looking to gain control over a region as a by way of supplication of a populous too a fictional deity who obviously they controlled.
What really ticks my off is people regularly swear an honesty oath, in a coart of law no less, on some of these works of fiction. How fucked up is that!
Except that the scandals do have a direct impact on the viability of his plan. If DeLay is brought down out of office by the scandals, then it doesn't matter what he says, he won't have any power or influence to make anything happen. It is that simple.
Climate change maybe a large factor, especially if it resulted in dryer conditions. Still one of the ways that it is thought the Australian Aboriginal ancestors effected the australian environment was to use fire as an extensive hunting tool. Australia vegetation is setup to burn (and often require it for renewal), what humans did is to use controlled burns to flush out animals and catch them when they are fleeing the fire and most vulnerable.
The environmental issue is that it increased the frequency of burns, as they were intentionally lit instead of from natural causes (lightening strikes). It also decreased the intensity and size of the fires, as the fires were lit to be small and safe. So large infreqent blazes were replaces by small more frequent controlled ones. The real upshot is this change would have an effect on the make up of plant species and thus indirectly on the animals that feed on them.
Of course the advent of the use of fire in this way may have been a response to a change in the climate that created dryer conditions.
There is a false idea that native humans (on all continents) didn't impact the environment at all when they happened to arrive. This is obviously not true, a new species as dominant and capable as humans would obviously have a huge impact, but most societies were able to return to a stable equilibirum with the environment after a number of generations. What is the problem with our modern life is that we are continually changing our way of life almost per generation, and there is no way to return to equilibrium with this continued change if we don't actively seek an environmentally balanced sustainable society all the time.
You have to be more specific than the whole suite. The two wordprocessors are both very capable and in a very strange way complementarily compatible with a range of word document versions. So there is very little to differentiate the two functionally. I have used both extensively (used word to write several scientific papers, used openoffice to write my PhD thesis) I like openoffice better than word because it handles imbedded graphic more consistently and also in a more userfriendly way, words graphic import filters are more flaky than openoffice also openoffice puts captions to a picture in a ready made frame with the graphic instead of the three or four step obscure operation you have to do in word to achieve the same thing.
Excel and the openoffice calc are as limited as each other, and for my work both suck. The 256 column limit is number one on my hate list, also the really limited graphing and fitting tools are similarly bad on both. If you have lots of skills in excels macro language, stick with it, if you don't I really see no need to remain with excel.
Impress and powerpoint are similar when we are talking the average presentation. But where OOo falls down is that you have to turnup to give a presentation with you laptop ready to plug in. Many places now to prevent the laptop switching delay, where many speakers are presenting, load up the relavant speakers presentation from a single windows machine that simply runs the presentations. This is a problem for OOo as all of this is standardised on powerpoint, and OOo stills sucks at importing powerpoint
By the way, meta-analysis is a way to actually reduce costs of research by taking already available data (collected at considerable cost) and teasing a bit more information out of it. Also drug interactions can be complex, and you can't just assume that two different drugs combined together will have a predictable effect, therefore they have to be tested.
For exampe on the opioid study, that two different drugs (I imagine the specific types were specified) together have an additive effect on pain is actually not obvious if you know anything about receptor drug interactivity. The two drugs interact with the same receptor sites, now if one of them binds tighter to the receptor site and displaces the other molecule but doesn't stimulate the receptor as much as the other drug then the effect would be to decrease the effect from just the more stimulating but poorer binding drug by itself.
In what way possible is that easier than pulling the plug on the access port? They would have to setup a much more complicated setup, as the current setup is probably not more than an open cheap wireless access point to a reasonable highspeed internet connection, of some seperate sever that is gating internet access using a web interface code entering page that excepts a code that is printed and registered with the system with a purchase at the till. This is not a simple system to implement independently and yes there are commercial solutions but it will probably an order of magnitude or more higher in cost than simple system they already have.
It makes sense to see if the unlimited internet access is really a problem on weekends (which it is) before even thinking about implementing this by shutting off the internet access and seeing what happens.
Now my point on MAD is that it is untouchable military superiority, you attack us we will attack you and both of us will die, therefore you can't touch us. The US never obtained absolute untouchalble military superiority with impunity (ie they could attack who ever they wanted), and still hasn't. What the US was able to do was force the stalemate into the economic sphere and win there, but it was not over miltary superiority
So lets look at this logically. By your understanding nations can only be free by an unchallengable military superiority, which if I am not mistaken really means being a nuclear power (the whole MAD thing dictates the modern case of an unchallengable military force), therefore by your logic to be a free nation, requires the development of an extensive nuclear arsenal. Therefore for any country hoping to be truly free they must establish a nuclear weapons program.
Modern warfare demands uncomfortable compromises in international affairs.
No actually what it says is that Pennsylvania can't stop delivery of wine from californian distributers or wineries if it lets pennsylvanian distributers or wineries deliver wine. Pennsylvania can outright ban all home delivery of wine, local or from across the country but it can't favor local wine merchants and producers. They can "protect the children" that way if they wish to legislate it.
Now why is it on slashdot? I guess one of the editors likes wine.
I like it because it provides the opportunity to get small volume wines easily from the US and around the world. US wines direct from the winery, and imported wines from small importing and distribution businesses that now don't need large distribution networks to reach the whole nation.
Also used to be used a lot in self-propeled harversters before hydrostatic drives, so the engine and threshing machinery could be run at a constant speed, but with the ability to control the speed of the harvestor.
E.Coli is a bad choice for a metaphor. E.Coli is one of the most important foundation organism for the explosion in molecular biology and biological research generally. It is without question the best understood organism at a biochemical level around, and that knowledge.
It's really can't work that way. Very simple, what ever is an OSS killer app may be based around linux, but it will have ports to all the other OS's because there is nothing to stop someone porting it. If it is a commercial app, it makes no sense for the company to restrict itself to linux.
What linux will have in its favour is what it already has, a high quality opensource operating system, to go with other high quality opensource applications as they come into prominence.
The problem is as you pointed out, these specialty apps that everybody runs. But that is really a legacy issue and these are the apps that lag behind in any change in platform that has occured in the past. A good question to ask is what system did they use during the 90's. I bet you it wasn't a windows based solution, but probably either a unix or dos based one. The shift to the new windows based software took a long time, and only when the budget allowed.
Any major shift to a platform is going to occur first in more generic computing environments without a lot of specialty apps. Like general office word-processing environments. The specialty software vendors will follow.
The World war II what if game can go on for hours. So anyway, what if Germany didn't declare war on America? It is hard to conceive of america entering into Europe after just starting the campaign against Japan, without Germany having declared war first. Sure FDR wanted to enter the war in europe, but if the US was already embroiled in the pacific the opposition to further miltary commitments would have been very high.
The result of the US staying out would have probably been the defeat of Germany sometime later at the hands of russia. With russia taking a large part of western europe along the way.
Now how about this, the worst case scenaria, What would have happened if Japan instead of attacking pearl harbor had attacked russia like the germans wanted them to and left the US alone (till later). Well the key here is if FDR could have gotten the political support to enter the war or not. If the US didn't enter the war, germany and Japan attack russia from two fronts and quite likely succeeded in taking over russia splitting it between japan and germany. If the US comes into europe then d-day may still have happen and germany may have eventually get its arse kicked, but it would have been a lot harder for the allies. For instance if the US is in the war in europe and russia had fallen to the combined russian japanese attack then the allies are fighting against the full german army, and Japan is free to continue its ambitions in the pacific, including opening up the pacific war with the US, except now germany and japan are fighting with russian oil and other resources, and have factories and refineries to far away for the allies to bomb. Germany has also had time to develop their military technology, and the resources to deploy them (for example by 1944 germany had developed a number of jet fighter and bomber designs far superiour to what the allies had or that were in the development pipeline, but the germans didn't have the resources to really build and deploy them). Then there is a question of the A-Bomb, who develops it first is a big question mark especially if the US is late entering the war (say 1944-1945) and doesn't start the manhattan project till then.
There are plenty of what ifs you can make about the decisions that Germany, japan and the US and other allies made during WWII, some with scary outcomes. But all I can say is the good guys did win in the end.
Some of the studio and dj sennheiser are like that, a tiny 1/8 inch stereo connector into the headphones, and you can replace the cord relatively cheaply (compared to buying new headphones). I have a pair of HD200, which are probably close to the cheapest pair that have this feature (got then on special for 75 australian), but they are pretty good sounding still and slimline for fully enclosing headphones. Also accidently yanking the cord only ends up with it coming out of the headphones, instead of breaking the wire connection in the headphones themselves.
Much of science conflicts with literal interpretations of the bible.
For example anything that puts the age of the universe and humans past 7000 years. This includes, paleontology, some archeology, geology, astronomy. While all areas in the biological sciences are very much dependent on Evolution, and can not be properly understood without accepting evolution. Physics in many ways is striving for a complete understanding of the universe via various laws and rules that don't involve god. And chemistry usually overlaps with all the other disciplines so much, it is in conflict by proxy. So you see that there is very little of science that doesn't conflict with literal interpretations of the bible.
-um, no.... You are spouting a lot of myth and misinformation. He is talking about the GDP, which obviously includes all private and public contributions. It is pretty consistent that the actually real costs of health care are significantly lower in western countries with universal government run health care systems than the private system that the US has. The reason is that the private system is regulated up the wazoo because of the fundamental need to guarentee good quality healthcare, every aspect of healthcare has a government accrediting agency to regulate it, drugs hospitals doctors nurses insurance companies etc., so it is effectively a public and private amalgam with a lot of beurocracy, and because of all the different parties involved in the system it is quite a fractured and inefficient beurocracy that drive up administrative costs. Add in the profit being creamed off by the for profit agents in the system and you all of a sudden have a very inefficient beurocratic and expensive system. A public systems simple does away with a lot of the middle men, with the government acting as both an insurance company, hospital administrator and regulatory agency under one all encompasing healthcare department, and in that way simplifies the red tape somewhat, and it also has a mandate to lower overal costs. Now I know you have had it beaten into you that private companies are always more efficient, but when an industry is so regulated that it is effectively being micromanaged by government, it ends up being more efficient to put it all under one goverment agency and be done with it. You could try and relax government regulation, but that generally is not looked upon favorably by the general public as it will generally increase in inequities in the system and also be scuttled by the first news story about some doctor, hospital or drug company that cuts some corners exploiting the relaxed regulations and harms somebody (note all the calls for the FDA to have even more oversite and regulating abilities after the problems with vioxx).
You my friend are a class A dickhead, and I feel very sorry for your neighbours. Most dangerous scenerios I have seen involving motorcycles on the road have been usually the result of something stupid the bike rider did, most often from weaving through city traffic with very little thought to safety and trying to go twice or more the speed of the normal car traffic.
