OU basketball notebook: Sooners' late-game strategy a success
With the Sooners owning a 61-58 lead with 9.3 seconds left, Oklahoma coach Lon Kruger instructed players to foul Kansas State once they crossed midcourt instead of allowing the Wildcats to attempt a potential game-tying 3-pointer.
"We typically will do that, up three under six or seven (seconds)," Kruger said.
K-State's Jordan Henriquez made both free throws with 5.2 seconds remaining.
The Wildcats fouled Sam Grooms, who hit two free throws with 4.8 seconds left to give OU a 63-60 lead. That would be the final points. K-State's Rodney McGruder's 22-footer at the buzzer hit the back of the rim.
"We obviously meant to foul again with two or three seconds to go and we didn't," Kruger said. "McGruder had a real good look at it. He shot it great. It just didn't go."
The Sooners built a 10-point lead early in the second half, but momentum stalled when Steven Pledger, Andrew Fitzgerald and Romero Osby all picked up their third foul with more than 16 minutes left.
It got worse.
Pledger picked up his fourth foul with 10:56 remaining, Fitzgerald his fourth with 10:01 left. Both returned with 6:48 remaining. The only player to foul out was Fitzgerald with 5.2 seconds left.
"Coach did a good job getting guys in and out," Osby said. "We just played a little bit smarter (at the end). We still played aggressive but tried to play smarter."
Kruger and his staff wore tennis shoes Saturday as part of the annual Coaches vs. Cancer Suits and Sneakers awareness weekend, .
"Everyone has been touched by cancer," Kruger said. "It's a great cause. It's been a signature charity for the coaches association for years."

People, Don't believe everything you read on reddit. The phone is definitely going to work on Verizon, the only up in the air question is when you can buy a subsidized one. Also Verizon is not adding bloatware and definitely not locking it down....
I'm sticking with 5.0.2 for now, because I'm happy with it. Once all the bugs are worked out I'll update. Others should take note instead of complaining. Preview builds are like betas, they're not perfect and requires testing.

A bomb squad from Cherry Point has secured a land mine at New Bern's yard waste facility after it was found in the trash.
Police spokeswoman Beth Stevenson says city workers sorting through trash have found the bounding anti-personnel land mine at the facility off Country Club Road.
The bomb squad secured what is commonly call a "Bouncing Betty" and will take it back to Cherry Point. Police say that land mine was not live.
The land mine did have its explosives intact, but there was no fuse.
Police say workers may have previously sent one other land mine onto the county landfill in Tuscarora, not realizing what the device was.
The bomb squad searched the landfill, but left without retrieving the second mine. They feel that device is buried. They say just like the other land mine, it is harmless without the fuse.

You're probably making some minor mistake, like switching the eyes or parts of the fossil. Just keep switching things over and you'll get it.

Local man denies domestic assaultApril 17,2013Local man denies
domestic assault
A Mendon man charged with beating and choking a woman last week was jailed on $10,000 bail Monday after denying felony domestic assault.
Tristan L. Taylor, 29, pleaded innocent in Rutland criminal court to a charge of aggravated domestic assault in the second degree. He remained behind bars Tuesday in the Rutland jail.
Rutland City Police arrested him Friday night after they were called to an apartment on Grant Street by a woman who said Taylor assaulted her during an argument. The woman told police Taylor kicked her, grabbed her by the hair and threw her onto a bed where he allegedly choked her.
The woman told police she tried to fight back by biting and kicking and flailing her arms.
Taylor was not at the home when police arrived, but he was found shortly after at the corner of Elm Street and Grant Avenue. He told police he had just been attacked by a group of people who pulled up in a car and beat him up, according to court records.
If convicted, Taylor faces up to five years in jail.MORE IN This Just InAnti-refugee activists are hosting a speaker at the Rutland Free Library tonight. Full StoryA Clarendon man pleaded innocent to his fourth DUI charge and a related charge in Rutland... Full StoryMan denies

It still upset me in a big way and Im at a loss of what to do as of this writting. The good news is I will be designing a page for the site on all the acc. that we sell so there are no mistakes or excuses of not knowing what we have, even though they can always email us. The big things for me is trying to keep everyone happy and that is so hard at times because of all the problems of us getting the right stuff or material that is a perfect match. As I explained earlier today to a friend I will get white material and then cut and print my centers then when I go to order again so I can make more kites the supplier tells me no big square only small but Ill have it for you in 90 days what do I do shut down production, of course not I get good material and things will have to be a little different.No wonder my head hurts..................Ben :?
play its Kiteworld in clacton. Beach,dont think you can do anything, i just think its the way things as on this side of the pond. regards Derek

This is a Group Loan
In a group loan, each member of the group receives an individual loan but is part of a larger group of individuals. The group is there to provide support to the members and to provide a system of peer pressure, but groups may or may not be formally bound by a group guarantee. In cases where there is a group guarantee, members of the group are responsible for paying back the loans of their fellow group members in the case of delinquency or default.
Kiva's Field Partners typically feature one borrower from a group. The loan description, sector, and other attributes for a group loan profile are determined by the featured borrower's loan. The other members of the group are not required to use their loans for the same purpose.

Despite a heavy investment in paid search, 66% of the traffic at big box retailers' web sites comes from non-paid clicks.
Big box retailers' web sites drove more than a billion search visits from July 2008 to July 2009, collectively spending about $678,000 per day on more than 1.2 million paid keywords, according to "The Big Box Retail Industry," a new report from search engine optimization technology vendor Conductor that analyzed the search traffic of the top 10 big box retailers in the third quarter. Yet, despite the heavy investment in paid search, 66% of their traffic overall came from natural, or non-paid clicks.
Though natural search drove a higher percentage of search activity overall for the group, individual retailers varied widely in their search marketing strategies. For example, the web sites of Wal-Mart Stores Inc. and Target Corp., which are the big box retailers that get the most search traffic, employed very different approaches to search.
Wal-Mart, No. 13 in the Internet Retailer Top 500 Guide, averages 19 million search visits per month. It gets 91% of its search traffic from natural search and only 9% from paid search, on which it spends an estimated $9,000 daily. (A PDF version of the financial and operating profiles of the retailers mentioned in this article can be ordered by clicking on their names).
Among the retailers studied, Costco Wholesale Corp., which ranks tenth in overall visitors, is an outlier, spending only $109 on paid search per day, the report says.
Direct competitors in the home improvement category, the Home Depot Inc. and Lowe's Cos. Inc., receive nearly the same volume of overall visitors. Home Depot receives 49% of its search traffic from paid search, spending $51,842 per day, while Lowe's gets 40% of its search traffic from paid search at a daily spend estimated at $40,498, according to the report.
Wal-Mart is No. 76.
The report gauged whether a retailer was optimizing for a natural keyword by determining whether the retailer's listing appeared high in natural search results for the keyword, with a high ranking suggesting that the retailer was, in fact, actively managing it for natural search.
The first step to eradicate price warfare in the retail industry is to widen the ...
