The poll found 17 percent of blacks and 8 percent of whites believe race relations have improved under Obama.The poll was specifically about the Ferguson, MO situation and Michael Brown shooting, but did ask this generic question as well as the general view of police relations. The times reports 1,025 people were polled by telephone and subclassified in all sorts of ways. Average margin of error was 4 points.
Kyron MAX is a new line of injection-moldable composites, with both glass and carbon fiber versions, from Piper Plastics. The material comes in three performance levels. Depending on the combination of polymer type and fillers, tensile strength can reach from up to 50,000 psi (345 MPa) to as high as 120,000 psi (827 MPa). That last figure puts it above steel, Dave Wilkinson, materials engineering manager for Piper Plastics, told Design News. Tensile modulus ranges from up to 5 million psi (35 GPa) to as high as 12 million psi (83 GPa).Pictured here, Piper Plastics used one of the highest-performing XS series Kyron MAX polymer grades to mold a standard #10-32 bolt for replacing titanium aerospace bolts. The part exceeds target minimum tensile load at 741 lb and double shear strength at 1,890 lb while reducing the weight of the titanium bolt by about 60%. They also say it beat the cost targets but don't say if it's supposed to be cheaper than the titanium bolt; with that kind of weight reduction, it might well cost more. (Source: Piper Plastics)
The composites are almost 75% lighter than steel and about 60% lighter than titanium. Polymers include PEEK, PPS, PEI, PPA, and PA. "The strength of any fiber-filled polymer is the strength of that fiber combined with the strength of the fiber's adhesion to the polymer," Wilkinson told us. "So we've developed a stronger fiber and a new sizing technology to adhere the fiber to the polymer. Depending on the application's mechanical strength needs, we use either short or long fibers."
Salmon are amazing fish. They’ll swim hundreds of miles against the current, hurl themselves up waterfalls, and risk being eaten by bears as they return to their birthplace to spawn. But some obstacles are too much, and that’s where Whooshh Innovations comes in. Behold, the salmon cannon. Seriously, watch this video of fish getting launched out of pneumatic tubes:
So they put a tilapia into the fruit tube and let it fly, proving both fish and fruit are subject to Bernoulli's laws. Whooshh is aware of the giggle factor here. To quote Todd Deligan, Whooshh's vice president:
Whooshh Innovations ("Whoosh" was already taken) first designed its tubes to transport fruit, but as Washington state debated what do about hydroelectric dams and the salmon whose migrations they blocked, the company saw its technology might have another purpose. If Whooshh tubes could send apples flying over long distances without damaging them, maybe, an employee thought, they could suck fish up and over the dams blocking the Columbia river.
"At a talk at the National Hydropower Association, I hit play on the video and the first fish goes flying out, and the audience is dying. I had to say, 'It's okay to laugh, this is utterly ridiculous.' Then people start talking and they say, 'Holy cow, why hadn't we thought of something like this before?'"The salmon cannon isn't fully operational, but they have tested it by destroying Alderan, a small planet on the edges of the empire ... no, sorry ... they've tested it a couple of times in the Columbia River system.
The test in June showed that fish will voluntarily enter the tube. When they swim into the entrance, the vacuum sucks them in and gives them initial boost; after that, elevated pressure behind the fish keeps them moving at about 15 to 22 miles per hour till they go flying out the other end. The speed, Deligan says, can be adjusted. Mist is applied to keep the fish wet as they zoom along. Currently the tubes are being hand-loaded, but Deligan says the test at the Roza site showed that "the fish just swim right in."More tests are planned, but unless something bad shows up, it looks like someday you might see salmon flying to get around dams. Without chartering airplanes.
This new paradigm is obviously powerful, but it also comes with its own risks and challenges. As the devices in your world come to know your life in more detail, they also come to know your life in more detail. You might appreciate it if your technology automatically responds to an intimate moment by lowering the lights and changing the music, but you may be uncomfortable with the idea of a large corporation like Google knowing the when and where of your love life.Do people really want privacy? Or are they willing to sell it for "cool" and convenience. As the author of that article commented:
If people really want privacy, market pressures will force someone to offer it, but my suspicion is that people won’t actually care as much about privacy as much as they say they do.
A new material structure developed at MIT generates steam by soaking up the sun. The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water. When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the material’s pores, where it evaporates as steam. The brighter the light, the more steam is generated.
The new material is able to convert 85 percent of incoming solar energy into steam — a significant improvement over recent approaches to solar-powered steam generation. What’s more, the setup loses very little heat in the process, and can produce steam at relatively low solar intensity.
By contrast, the MIT approach generates steam at a solar intensity about 10 times that of a sunny day — the lowest optical concentration reported thus far. The implication, the researchers say, is that steam-generating applications can function with lower sunlight concentration and less-expensive tracking systems.This is preliminary and hasn't been scaled up to full production, but it's something to keep an eye out for. The obvious advantages for sterilizing water in places with too much wildlife in their water supply are just one use. Don't neglect sterilizing surgical instruments for field or bush hospitals.
"Christianity in Mosul is dead, and a Christian holocaust is in our midst," said Mark Arabo, a Californian businessman and Chaldean-American leader. In an interview with CNN's Jonathan Mann, he called what's happening in Iraq a "Christian genocide" and said "children are being beheaded, mothers are being raped and killed, and fathers are being hung."The article concludes with:
"Right now, three thousand Christians are in Iraq fleeing to neighboring cities," he told Mann. Arabo is calling on the international community to follow France's lead and offer the Christians of Iraq asylum.
...
"They are systematically beheading children," Arabo repeated slowly. "And mothers and fathers. The world hasn't seen an evil like this for generations."
"There's actually a park in Mosul where they actually beheaded children and put their heads on a stick... this is crimes against humanity. They are doing the most horrendous, the most heart-breaking crimes that you can think of."
A quick scan of Youtube shows the truth of what Arabo is saying - there are gruesome videos of heads on spikes, and many of live beheadings (one poor Christian is forced to say the Shahada 'there is no God but Allah and Muhammad is his Prophet' and then beheaded anyway.)It's melodramatic to blame this on Obama: no one is responsible for these crimes against humanity except for the Islamists, but this outcome is completely predictable given the things Obama has done already. Completely predictable in light of all the stories I've covered before. You might recall that the leader of ISIS said he's coming to America, and the media was full of stories this weekend reporting how they are threatening to do so immediately, and "raise the flag of Allah in the white house".
Warning: don't google these things unless you have a strong stomach.
“I say to America that the Islamic Caliphate has been established,” spokesman Abu Mosa told VICE Media in a video interview. “Don’t be cowards and attack us with drones. Instead send your soldiers, the ones we humiliated in Iraq.”The soldiers they humiliated in Iraq? What definition of humiliation would that be? Regardless, these horrific savages (and there are no other descriptors for people who would behead children in front of their parents) are on the march. The flag of ISIS was flying in London and elsewhere in Europe this weekend, and only a 77 year old nun had the guts to tear it down.
Mosa, however, wasn't finished: "We will humiliate them everywhere, God willing, and we will raise the flag of Allah in the White House,” he added.
There is a phrase used of, and by, jihadists: ‘First the Saturday people, then the Sunday people.’ Well there’s a fine example of this on display at the moment in East London. Even the Guardian has picked up on it.I don't know what the right thing to do about ISIS is, but I suspect the answer comes awfully close to what they'd say: "kill them all and let God sort them out". I do know that if you don't think you have a dog in this fight, you'd better get your head out of your butt. They may come for the Jews first (the Saturday people) and then come for the Christians, but they're coming for everyone, unless someone stops them. If the neighborhood lunatic came up to you and vowed he was going to kill you would you take it seriously? I personally always say that when someone swears they are going to kill you, you'd best take them at their word. It doesn't matter if you don't want to get into a "religious war" if they do. If you're completely atheistic and think it doesn't matter when they tell you convert or die, good luck with that. You might want to look up the terms "dhimmitude", "jizya", and how the Muslims think if you're not one of them, you're essentially not human, and they can kill you any time they feel like it.
At the entrance to a council estate near Canary Wharf, amid the banners of the hilariously misnamed ‘Stop the War coalition’ (‘End the Siege on Gaza’) the Black flag of Jihad is flying. Yes, that’s right, at a major council estate in the East End of London the black flag of ISIS is flying.
While you can physically fire either 308 or 7.62 NATO from a 308, you will see reduced accuracy from increased wear in the throat of the rifling and a higher chance of erratic cycling, including a higher chance of failures to extract. It is for this reason we recommend using only commercial 308 in a 308 barrel.Pretty serious, huh? If you use Mil ammo in your DPMS .308 rifle, you void the warranty. After cruising forums and various experts, I saved this bit of wisdom.
DPMS does not recommend or warranty the use of 7.62x51 ammo in a .308 chamber.
OK, lets clear up this .308/7.62 business once and for all. Both rounds can be used in either chamber, however there are a few things you need to be aware of if using .308 in a 7.62 chamber.Although I've had that in text file on my computer for a few years, I didn't keep track of where it came from. If it's yours, I'd be happy to credit it to you. For everyone else, heed the last paragraph.
First, realize that .308 and 7.62 have identical external dimensions. Because of this they can both be used interchangeably.
That said, it's important to note that a .308 case has a larger internal dimension than a 7.62 case. The walls on a 7.62 case are thicker than that on the .308. The result is that the 7.62 case is stronger, but the .308 case can have a higher potential load.
This is important to note because for the .308 the combination of a thinner wall, with a higher charge, means the case can be more easily deformed when fired. This is why the .308 chamber is a tighter spec, in order to restrict expansion of the case.
The 7.62 chamber is a slightly higher tolerance (which can aid in reliability, as it is not incredibly picky about round dimensions) which is fine for the thicker walled 7.62 case (thicker case = less likely to deform), but may present an issue when using .308 with a high charge (easier to deform).
Also of note is that while .308 is CAPABLE of a higher charge, it is often not loaded to max spec by manufacturers. 7.62 on the other hand often is loaded closer to it's max spec, and as such they tend to be "hotter" than commercial .308 rounds.
Lets break it down:
7.62 = Thicker case, lower possible max load, but is often loaded to near it's max.
.308= Thinner case, higher possible max load, but is almost always loaded lower than it's max.
7.62 chamber = higher dimensional tolerance (loose)
.308 chamber = lower dimensional tolerance (tight)
You can use 7.62 rounds in a .308 chamber with no problem (cheap surp might be a little tight though), and you can use .308 rounds in a 7.62 chamber as long as you don't reload using too high a charge. If you DO use an overly high charge for a .308 round in a 7.62 chamber, you are likely to deform the case, or tear the head off the case.
If you don't reload at all, you don't need to worry about it (unless you bought handloads).
So sure, ideally it would be good to use the round your chamber was made for, but by no means do you have too. For most, they can use either chamber, either round, and will never have any issue.
And remember people, this is the internet. Do not simply believe everything you read just because it may sound good... even from me (and even though the above is accurate). Please go out and research for yourself in order to confirm what I'm telling you.
The movie is by inventor Tim Jenison and his friend Penn Jillette (the Vegas magician) who directs. It shows how Jenison works more than eight years to accurately recreate the art of 17th-Century Dutch Johannes Vermeer, the painter of such highly realistic Masters as Girl with a Pearl Earring and The Concert.Cameras obscura are totally enclosed thin-walled boxes with holes on opposing walls. Light travels in straight lines from the scene being painted through a small hole, cross, and project through the opposing hole as an upside-down image on any surface put in front of it.
Not only that, but Jenison uses all the tech-based techniques Vermeer used — with heavy reliance on a camera obscura.
Among the UN’s long bill of particulars against the beleaguered Jewish state comes the almost unbelievable accusation that Israel’s refusal to share its Iron Dome ballistic missile defense shield with the "governing authority" of Gaza – i.e. Hamas, the terror group created to pursue the extermination of the Jewish state and now waging a terrorist war against it – constitutes a war crime against the civilians of Gaza.But, Madam Brain Dead, isn't it the fault of the attackers when the people they're attacking eventually strike back?
The UN chairwoman criticized the U.S. for helping fund Israel's Iron Dome system which has saved countless Israeli and Palestinian lives. "No such protection has been provided to Gazans against the shelling," she said.
Just because Hamas fires rockets indiscriminately aimed at Israeli civilian population centers without provocation and fires them from within its own population centers does not “absolve” Israel from its own legal violations, Pillay told reporters Thursday.Tell me that there are higher mental functions going on in that so-called "brain". I think anyone with half a functioning brain - I've even heard it from UN Secretary General Ban Ki-moon - knows that Hamas is surrounding all of their military hardware with civilians. With their own babies. It's the ultimate hostage situation; they're holding their own people hostage, hoping the Israelis kill them. It's like strapping each Hamas soldier with a dozen babies. Hamas is doing their absolute level best to guarantee civilian casualties. They want them. They count on them. They know that civilian casualties are the only way they can "win" this war. In the press. With the "low information voters", the useful idiots, and the rest of the media.
Marking the end of her contentious, six-year term as chairman of the notoriously anti-Israel UNHRC, Pillay saved her harshest condemnations for what she termed Israeli "targeting" of UN-run schools and hospitals in Gaza. She did not mention, nor was she reminded by any of the reporters present, that as of this writing, at least three UN-run schools in Gaza have been used as rocket warehouses, a gross violation of international law that clearly falls within the category of war crimes. Neither did she mention, nor was she reminded, that in at least two of the three cases cited above, the terror rockets found on UN property in Gaza were returned to Hamas by the UN.Regrettably, she's not alone in not supplying a gram of Zombie Chow. The Blaze reports today that a reporter for the Finnish "Helsingin Sanomat" filed a report on a missile being fired at Israel from a hospital, the same hospital hit by a Hamas missile earlier this week, a missile that Israel's IDF recorded the launch and impact of. But instead of thanking Israeli news reports for using her story and byline, the brain dead reporter was offended that her report was being used by Israel. Gosh, we sure wouldn't want any truth getting out now, would we?
