Ames Laboratory part of team that found magnetism may be responsible for superconductivity in iron-based superconductors
AMES, Iowa -- In traditional electrical lines, a significant amount of energy is lost while the energy travels from its source to homes and businesses due to resistance. Superconductors, materials that when cooled have zero electric resistance, have the promise of someday increasing the efficiency of power distribution, but more must still be learned about superconductors before they can be widely used for that purpose.
Scientists at the U.S. Department of Energy's Ames Laboratory are using specialized techniques to help unravel the mysteries of a new type superconductor that was discovered in 2008. Ames Lab physicists were part of an international collaboration that also included scientists at Kyoto University in Japan, University of Illinois at Urbana-Champaign and University of Bristol in the United Kingdom to study the materials.
The group found that magnetism may be helping or even responsible for superconductivity in iron-based superconductors. The results were published in the June 22 issue of Science.
"The first step in designing superconductors for new technologies that will help save energy is better understanding of how superconductors work," says Ruslan Prozorov, who led the team at Ames Lab that also included Kiyul Cho and Makariy Tanatar.
Unfortunately, most conventional measurements of material parameters, such as resistivity, aren't useful in the state of superconductivity. But Prozorov several years ago helped developed a technique to measure how far the magnetic field penetrates into a superconductor. This length is called the London penetration depth, and it reveals basic information about a material, even in the superconducting state.
"London penetration depth is one of the few quantities we can measure in a superconducting state to learn more about what's going on, so the technique we specialize in here at Ames Laboratory was particularly useful for this research project," said Prozorov, who is also an associate professor of physics and astronomy at Iowa State University. "In this collaboration, we studied a barium-iron-arsenic-phosphorus material at near zero Kelvin, and our London penetration depth measurements suggested that magnetism is responsible for superconductivity in iron-based superconductors. Typically, magnetism is detrimental to superconductivity, but when it is weakened enough, it might actually be helping."
The international team's research helps answer one of the central questions about how iron-based superconductors work.
"Iron-based superconductors may open the door to new energy technologies," said Prozorov. "But we'll only get there through materials science and understanding the mechanism of superconductivity in these new iron-based materials."

Exercise, even mild physical activity, may reduce breast cancer risk
ScienceDaily (June 25, 2012) ? A new analysis has found that physical activity -- either mild or intense and before or after menopause -- may reduce breast cancer risk, but substantial weight gain may negate these benefits. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings indicate that women can reduce their breast cancer risk by exercising and maintaining their weight.
While studies have shown that physical activity reduces breast cancer risk, many questions remain. For example, how often, how long, and how intense does physical activity have to be to provide benefits? Also, do women with all body types experience a reduced risk when they exercise, and does exercise reduce the risk of all types of breast cancer?
To investigate, Lauren McCullough, of the University of North Carolina Gillings School of Global Public Health in Chapel Hill, and her colleagues looked for a link between recreational physical activity, done at different time points in life, and the risk of developing breast cancer.
The study included 1,504 women with breast cancer (233 noninvasive and 1,271 invasive) and 1,555 women without breast cancer who were 20 to 98 years old and were part of the Long Island Breast Cancer Study Project, an investigation of possible environmental causes of breast cancer.
Women who exercised either during their reproductive or postmenopausal years had a reduced risk of developing breast cancer. Women who exercised 10 to 19 hours per week experienced the greatest benefit with an approximate 30% reduced risk. Risk reductions were observed at all levels of intensity, and exercise seemed to preferentially reduce the risk of hormone receptor positive breast cancer (ER or PR positive), which is the most commonly diagnosed tumor type among American women.
"The observation of a reduced risk of breast cancer for women who engaged in exercise after menopause is particularly encouraging given the late age of onset for breast cancer," said McCullough.
When the researchers looked at the joint effects of physical activity, weight gain, and body size, they found that even active women who gained a significant amount of weight -- particularly after menopause -- had an increased risk of developing breast cancer, indicating that weight gain can eliminate the beneficial effects of exercise on breast cancer risk.

Online marketing and reputation management: why it is necessary
With use of the internet, details about companies and people can easily be bought. Individuals who want to explore someone or something like that will in the end result in a search by title or company products. With any kind of information collected in the digital and print media posting, the issue of if the information received is definitely accurate.
With social networking and blogging platforms for example and WordPress.com, the arrival of real-time-point commentary on companies and people, it?s now possible. Some positive comments about the organization or person, frequently there?s not a problem. However, when negative surveys are released underneath the title of the individual or brand ? that information can linger on the web and cause revenue loss, mistrust, and insufficient respect for unpredicted problems.
Online reputation management is really a bornBefore social networking an internet-based marketing even been around, reputation management professional abilities. Creating the reputation of the individual, company or organization?s pr specialists within the domain. If someone?s title or the organization made it the scandal, which may adversely tied its brand, or perhaps a media event, story, novel, or other kind of place, a pr firm was hired to positively fight discharge of information and proper errors. Today, pr specialists continue to be utilized by these abilities. Pr professionals usually operate in celebs, political figures, religious and business leaders along with other experts who are able to afford to pay for high monthly retainers. To effectively achieve a larger audience of more print, television and radio advertising budgets will also be needed.
The main difference between your online reputation management and traditional PRMany online marketing companies offering reputation management services, direct internet access media. Experts who monitor the web reputation management company or organization normally has an expert background in pr. But it isn?t just necessary skills. Online marketing world, an individual who monitors the individual?s or company?s reputation ought to know how to make use of social networking and blogging service to achieve visibility in internet search engine search engine pages (SERPs). With time, social networking and blogging service, to incorporate new people from the programming and functionality. Professionals employed in online reputation management to help keep pace with one of these changes and know precisely how you can implement methods for his or her clients.
The impact of social networking online reputationGood or bad, wrong or right, every single day, people you can write their sights and opinions abound on the web. Those who have this kind of information online might have an ax to grind, or possibly the best concern. This may be dissatisfied clients, providers or former or current employees. Reputation management ?scrub or remove negative comments isn?t a strategy ? a reaction.? Facebook presently enables people to get rid of comments that aren?t acceptable. However, a hostile response or negative effects may happen to be felt.
Other social networking platforms for example Twitter and LinkedIn doesn?t allow people to remove comments. Online review sites like Yelp, trade circle or ?Google? you will find other areas where people can ?vent. Should you web or blogsite, that is possessed and handled by another company or person is offensive or any mistakes about the organization or person ? the written text cannot be simply removed. Actually, these kinds of comments can survive for quite a while. If no fact is crafted and written by the pack leader or company can experience reduced prospecting, customer retention, or damage entirely or title.
How Warrant Buffett once remarked, ?It requires two decades to build up a reputation and 5 minutes to ruin.?
How you can evaluate a business sells the next Online ServicesNo legitimate company selling reputation management services not just to recommend to remove any comments. Rather, it?s possible the Online marketing agency offering this particular service one step in the overall game and craft an sufficient reaction to the brand new ?spin? problem. Much like its traditional links with society on the planet alternatives, online reputation management services companies to provide their clients the possibilities and techniques to reduce the effects of the negative comments and provide your clients, providers or employees from the solution.
If lewd comments appear high internet search engine ratings by company title or trade title of the individual, internet marketing and pr methods is going to be suggested and carried out to push the very first couple of pages of harmful your website searching results around the following pages.
Based on the 2010 October. Media audit carried out within the U . s . States, Internet customers save money minutes 3X blogs and social media because the answer and write e-mails. ? Which means that the typical user is hearing the chatter on the web. Individuals are frequently very you should consider these details before leasing or purchasing a business or perhaps an individual. Because the information highway is crowded using the small things that switch off prospects, clients and clients, reputation, management abilities tend to be more sought after of computer has ever been.
