On my Samsung Galaxy Facebook adds a fourth icon a the bottom of the screen that opens facebook settings. The settings contains a button to delete conversations.
I just got a new Nexus 7. Facebook does not add the icon on the Nexus. I can long-press an individual message and get a pop-up to delete the message but it doesn't work for the whole conversation.
How can I delete a Facebook conversation on the Nexus 7?
CASL milestone validates reactor model using TVA dataPublic release date: 10-Jul-2013 [ | E-mail | Share ]

Today, the Consortium for Advanced Simulation of Light Water Reactors (CASL) announced that its scientists have successfully completed the first full-scale simulation of an operating nuclear reactor. CASL is modeling nuclear reactors on supercomputers to help researchers better understand reactor performance with much higher reliability than previously available methods, with the goal of ultimately increasing power output, extending reactor life, and reducing waste.
Simulation results from the Virtual Environment for Reactor Applications (VERA) program, developed by CASL, were compared with actual data provided by the Tennessee Valley Authority's (TVA) Watts Bar Nuclear Plant in Tennessee, which confirmed its accuracy.
"VERA's capabilities range from simulating single fuel pins to modeling an entire operational reactor core," said Jess Gehin of Oak Ridge National Laboratory's Reactor and Nuclear Systems Division. "It addresses operational challenges and supports increased power generation by exploring greater efficiency and life extensions."
During cycle startup of commercial nuclear power reactors, technicians perform a series of tests to confirm the reactor is operating as expected. For CASL, results of previous tests are useful for demonstrating the accuracy of the VERA software. As a CASL partner, TVA provided detailed historical information and measured operational data from the Watts Bar plant to allow comparisons of the VERA simulation.
The simulations of the reactor startup tests are just a first step in the demonstration of VERA. CASL is extending the program's capability to simulate full power operation of the TVA reactor, which will require further VERA development to integrate the nuclear and thermal hydraulic physics. These additional capabilities will allow researchers to pursue breakthroughs in understanding key phenomena in the operating reactors.
CASL, headquartered at ORNL, is one of the Department of Energy's Energy Innovation Hubs. First established in 2010, CASL brings together industry, academia, and national labs to provide advanced modeling and simulation solutions for commercial reactors. Its mission is to confidently predict the performance of nuclear reactors through comprehensive science-based modeling and simulation technology that is deployed and applied broadly throughout the nuclear energy industry to enhance safety, reliability and economics.
The Hub's 10 core partners include: the Electric Power Research Institute, Idaho National Laboratory, Los Alamos National Laboratory, Massachusetts Institute of Technology, North Carolina State University, Sandia National Laboratories, Tennessee Valley Authority, University of Michigan, Westinghouse Electric Company and Oak Ridge National Laboratory.

LISBON, Portugal (AP) ? Portuguese party leaders say a rift that threatened to bring down the government and caused turmoil on financial markets has been patched up with details of the coalition-saving pact to be announced Saturday.
The crisis was triggered by the resignation of two government ministers, and an accord was hammered out and presented to President An?bal Cavaco Silva late Friday, Popular Party spokesman Nuno Melo says.
Melo says the proposal "guarantees government stability" and says coalition leaders would later make a joint statement. He says the deal enables Portugal, which agreed a 78 billion euro ($102 billion) sovereign bailout, "to face future challenges."
The political instability rocked European financial markets during the week as the government teetered on the verge of collapse in a dispute over austerity measures.
The economy added 195,000 new jobs in June, beating economists' expectations of 155,000 jobs and matching the revised pace from May. Meanwhile, the unemployment rate remained unchanged at 7.6%.
Spring hiring was also stronger than previously thought. The number of jobs created in April was revised up by 50,000 positions, while May was revised higher by 20,000 jobs.
The report was being watched particularly closely by investors, in light of recent comments from Fed Chairman Ben Bernanke that caused wild swings in the markets.
Prior to Friday, the S&P 500 was down nearly 3% since May 22, when clues first emerged that the Fed may slow purchases of bonds and mortgages as early as this year. Bernanke later said the stimulus program could end altogether if unemployment hits 7% -- which the Fed expects by the middle of next year.
Despite no change in the unemployment rate, the underlying strength of the report led investors to believe that the bedrock of the economy is improving, and that the Fed will start to pull back sooner rather than later.
Stocks rose slightly and bonds sold off following the news.
For the last couple of weeks both stocks and bonds had been selling off, as investors fretted the Fed may be ending its stimulus program too early.
"Investors are beginning to believe that the economy actually may be strong enough to grow without the extreme monetary support," said Bill Hampel, chief economist at the Credit Union National Association. "When will we finally get back to the day when good news for the economy is taken as good news by the stock market? It looks like we might finally be there."

The report contained little in the way of bad news, with the size of the labor force growing and the participation rate rising slightly. The number of long-term unemployed people also fell.
The biggest job gains were in leisure and hospitality (up 75,000), professional and business services (up 53,000), and retail (up 37,000). Construction and manufacturing were little changed.
The federal government shed 5,000 positions, continuing a trend brought on by the budget cuts that have eliminated 65,000 jobs in the last 12 months.
The number of people working part time because they couldn't find a full-time position rose by 322,000 from the month before. Some experts also pointed out that many of the newly-created jobs are in low-wage sectors.
"Three quarters of these would qualify as low-quality jobs," said J.J. Kinahan, chief strategist at TD Ameritrade.
Still, Kinahan noted that wages in June grew faster than the 12-month average, and was pleased with the report overall.
"This proves what the Fed has been saying -- the economy is improving," he said.

One of the few groups reeling may be those looking for a mortgage. Interest rates on home loans have surged over the last few weeks.
On average, the economy has created roughly 182,000 jobs a month over the last year. That's not bad, but it's not great either. Economists say that level of job growth barely keeps pace with the rising population, and is a far cry from the 250,000 jobs a month created during the boom times of the mid 1990s.
