The design of routing protocol with energy efficiency and security is a challenging task. To overcome this challenge, we propose energy-efficient secured routing protocol. The objective of our work is to provide a secured routing protocol, which is energy efficient. To provide security for both link and message without relying on the third party, we provide security to the protocol by choosing a secure link for routing using Secure Optimized Link State Routing Protocol. Each node chooses multipoint relay nodes amongst the set of one-hop neighbors, so as to reach all two-hop neighbors. The access control entity authorizes nodes announcing the node identification to the network. In addition, the access control entity signs a public key Ki, a private key ki, and the certificate Ci required by an authorized node to obtain the group key. Each node maintains a route table with power status as one of its entry. After selecting the link, on requirement of a new route, we check nodes’ power status in its routing table and then accordingly arise a route. Then, we perform group key distribution using the generated keys using a small number of messages which helps reducing energy consumption. The group key can be altered periodically to avoid nonauthorized nodes and to avoid the use of the same group key in more than some amount of data. Then, we provide communication privacy for both message sender and message recipient using Secure Source Anonymous Message Authentication Scheme. Thereby, the message sender or the sending node generates a source anonymous message authentication for message for releasing each message based on the MES scheme. Hence, our approach will provide message content authenticity without relying on any trusted third parties. © 2016 Springer Science+Business Media New York

High-density polyethylene (HDPE) was graft functionalized with two different mercaptoesters in an inert atmosphere at 160°C under different experimental conditions by thermolysis method. The order of functionalization, crosslinking, and C=C formation reactions were determined from the relative intensities of carbonyl stretching vibration and C-H bending vibrations. FTIR, DSC, and TGA analytical tools were used to characterize mercaptoester- functionalized HDPE. A plausible reaction mechanism is proposed here to explain the experimental results obtained. POLYM.

Linear low-density polyethylene (LLDPE) was functionalized with succinimide under different experimental conditions like change in time, temperature, and (% weight of succinimide). The FTIR Spectrum inferred that melt grafting of succinimide onto LLDPE followed the 0.50 order of reaction with respect to (% weight of succinimide). DSC was used to analyze the (melting temperature) T m and (crystallization temperature) Tc values of functionalized LLDPE. Free radical mechanism explained the formation of nitroxide radical during the melt functionalization of N-hydroxy succinimide (NHS) with LLDPE in the presence of dicumyl peroxide. © 2009 Wiley Periodicals, Inc.

Bank’s spare change drive supports nonprofit’s goal of specialized facilities and targeted care for young people with cancer RALEIGH, N.C., Nov. 29, 2016 (GLOBE NEWSWIRE) -- Starting today (Giving Tuesday) and throughout the holiday season, First Citizens Bank is collecting spare change in all its branches to help teens with cancer. The effort, called “Open the Door to Change,” is the next phase of the North Carolina-headquartered bank’s ongoing sponsorship of Teen Cancer America. The spare change collected will go to the national nonprofit’s work to increase support for cancer care facilities and specialized treatment targeted for both teens and young adults. Individuals, businesses, school groups and civic organizations are encouraged to gather spare pennies, nickels, dimes and quarters and drop them off at any First Citizens location through Jan. 6, 2017. “A little bit of change from everyone can go a long way to helping young people with cancer,” said Jeff Ward, chief strategy officer of First Citizens Bank and a Teen Cancer America board member. “That’s why we’ve launched ‘Open the Door to Change.’ By collecting spare change this holiday season, we want to open more doors — to bring about even better care and brighter futures for these teens and their families.” There are three ways to participate in “Open the Door to Change:” In addition, First Citizens associates will join the effort by collecting and donating their own spare change. Every year, almost 11,000 young people in the United States between the ages of 13 and 25 are diagnosed with cancer. Teen Cancer America works with hospitals to create treatment and recovery spaces around the unique medical and psychological needs of teens who are fighting the disease. Teens often fall between the cracks of specialized care provided to cancer patients, according to Simon Davies, executive director of Teen Cancer America. They may end up with kids in the pediatric unit or with the older people in the general cancer facilities. “First Citizens’ ‘Open the Door to Change’ will help us bridge this gap — by supporting hospital facilities designed for teens, where they can get targeted treatment and where there’s staff trained to deal with the specific types of cancers we’re seeing in young people today,” Davies said. “We hope people all across First Citizens’ markets will open their hearts, donate their spare change and help us transform the lives of young people with cancer.” The “Open the Door to Change” coin collection drive is a continuation of First Citizens’ largest-ever philanthropic effort. As part of this effort, rock legend Roger Daltrey of The Who recorded a new version of the classic Pete Townshend song “Let My Love Open the Door” to serve as the centerpiece of the initiative. It was launched in November 2015 with the theme “Open the Door” to support the work of Teen Cancer America. Daltrey is a spokesman for and a driving force behind Teen Cancer America, which he and Townshend helped found in 2012 after more than a decade of working with Teenage Cancer Trust in the United Kingdom. Daltrey’s single is available exclusively on iTunes with Apple, Daltrey and Republic Records donating their respective proceeds in the United States to Teen Cancer America. The song is featured in First Citizens’ television and radio commercials encouraging support of Teen Cancer America. Most recently, the commercial ran as a public service announcement in California on KCET, the nation's largest independent public television station. It was part of special programming that focused on The Who, Daltrey and his involvement in Teen Cancer America. The song, the download and television commercial can be found at LetMyLoveOpenTheDoor.com. To date, Teen Cancer America has partnered with more than 12 major cancer centers across the United States to build specialized, teen- and young adult-friendly inpatient and outpatient cancer care facilities and programs. In cooperation with First Citizens, Teen Cancer America is talking with major medical centers in North Carolina and South Carolina about establishing teen-focused cancer units and programs. First Citizens’ financial commitment to Teen Cancer America includes contributions for the nonprofit’s work in partner hospitals that are within the bank’s key markets. First Citizens Bank is the principal Southeastern corporate sponsor of Teen Cancer America. For more information, visit LetMyLoveOpenTheDoor.com, use #LetMyLoveOpenTheDoor or stop by a local First Citizens Bank location. Founded in 1898 and headquartered in Raleigh, N.C., First Citizens Bank is the largest family-controlled bank in the U.S., with offices in 20 states. Drawing from over a century of experience serving the needs of its customers, First Citizens focuses on developing long-term relationships and offers a comprehensive array of products and services to individuals, families, businesses and the medical community. First Citizens Bank is a wholly-owned subsidiary of First Citizens BancShares Inc. (Nasdaq:FCNCA), which has more than $32.9 billion in assets. For more information, visit firstcitizens.com. Following in the footsteps of the highly developed and successful Teenage Cancer Trust –Teen and Young Adult Cancer Program out of the UK, Teen Cancer America is designed to help hospitals and healthcare professionals bridge the gap between pediatric and adult oncology care. Teen Cancer America aims to educate and support hospitals and outpatient facilities in the development of specialized units for this age group. The units are places just for teens and young adults where the cancer experience is understood and the importance of living life through the cancer journey is nourished. Teen Cancer America’s work also supports the coming together of physicians and allied healthcare professionals in both pediatric and adult oncology so that the teen and young adult cancer patient care becomes closer to where it needs to be.

When the Long Beach Opera unveils the first opera composed about the Iraq War experience, it will be the culmination of a painful eight-year journey to heal the soldier who inspired it, while at the same time offering civilian audiences a more visceral understanding of battle and its aftermath. Fallujah—written by Heather Raffo, a New York-based librettist of Iraqi descent, and composed by Tobin Stokes—was inspired by the experiences of retired U.S. Marine Corps Sergeant Christian Ellis, a machine gunner whose platoon was ambushed and bombed in the 2004 battle of Fallujah, Iraq. One of the few survivors, Ellis endured a broken back and debilitating PTSD. The opera takes place over 72 hours in a veteran’s hospital following a marine’s third suicide attempt. While his mother waits to see him, the soldier must first contend with the demons conjured by his time in battle. "I believe those who did serve will see this as authentic, and those who’ve never been to war will have a more realistic idea of what it is like to endure combat and continue to live with it," says Ellis, who served as the opera’s story consultant. The seven performances run March 12 through March 20. On March 18, the production will air live on KCET in Los Angeles, and simul-stream at KCET.org/Fallujah, LinkTV on the DirecTV and Dish Network, and Explore, an Annenberg Foundation philanthropic media organization. A KCETLink documentary on the making of the opera will premiere on KCET and Link TV on Memorial Day. Tickets for the live event can be purchased here. A daily average of 22 veterans commit suicide—more than die in combat. And PTSD effects not just soldiers, but their families, friends, and communities, and the health care industry. "It’s a story that’s socially relevant and has been told in many ways, but opera enables the music and story to open up on an emotional level that hasn’t been experienced yet, and to people not aware of these issues," says Andreas Mitisek, Long Beach Opera’s artistic and general director. "Sometimes it’s more meaningful than reading it in a newspaper. We hope this will open up more avenues for discussion about this topic." Before joining the marines at 19, Ellis had studied classical and jazz voice and trumpet. After returning, listening to opera was often a source of solace. Philanthropist and filmmaker Charles Annenberg Weingarten, the founder of Explore, met him at a retreat for recovering veterans in 2008 and encouraged him to write an opera about his war experience. Weingarten connected him with the City Opera Vancouver, which brought in Raffo and Stokes and workshopped the production in 2012. (Although an upstate New York company mounted an Iraq War-themed opera prior to this production, Fallujah was written and workshopped first.) Two other workshops at the John F. Kennedy Center for the Performing Arts and the University of Tampa, ongoing tweaks, and networking followed, until Mitisek—who’d been looking for an opera to tackle this subject matter—reached out in 2014. In crafting the story, Raffo’s biggest challenge was intertwining reality and memory to put the audience in the shoes of a person with PTSD. She achieved this by giving equal weight to those realities, having people from his war memories appear in his hospital room as daymares. "I thought about the kind of conversation I wanted the audience to be having with the show, the kind of national conversation we needed to have as a country, and the conversations I’d had with other marines and their family members about what they were dealing with," says Raffo. "What came up was the people with PTSD not talking about it with the ones they love. They have to come back home to intimate relationships after having experienced intense violence and trauma. The narrative became, how do you do that? "My work in the past focused on telling war stories through theater from the Iraqi perspective," says Raffo, who has an Iraqi father and American mother. "This enabled me to learn what it was like from an American military perspective. I knew the costs of war intimately from the Iraqi side of my family. But those costs are as prevalent with the men and women returning from Iraq." The bicultural landscape offered Tobin a great swath of musical influences, tonalities, and instruments, which include an electric guitar and Iraqi oud. "The setting presented a tremendously unique opportunity," he says. "I learned about Middle Eastern music and what Christian listened to on his iPod. They were opposing ends of a palette that could be used as influences to paint this world." While the project gave Ellis purpose, it forced him to confront issues he wasn’t prepared for, against a long arduous backdrop of realizing a creative passion project on a professional scale. He was also ill-equipped to deal the Hollywood mindset, mercurial nature of production, adjusting expectations, and promises that don’t pan out. He moved to Los Angeles to make contacts and prepared for a sprint instead of a marathon. With no job or sustainable infrastructure and still contending with PTSD, Ellis ended up going through his finances and spent some time homeless, before getting help. "I nearly destroyed my life pursing this," he says. "I had no choice but to face my demons. But had I not gone through what I did, I don’t think I would have been aware of some of the issues, and come out of it a stronger person. [Raffo] saw a bit of that and tried to put it in the opera." Raffo believes some catharsis will come with these performances. "What Christian hasn’t had a chance to experience yet is the fruition," she says. "We’re still in process. The first time he’ll see it onstage—in full production in front of an audience—and reap the joys is the world premiere on Saturday, and talking with audience members afterward. "The ups and downs are brutal enough for any artist, but he’s just served in the worst battles of the Iraq War and is recovering from PTSD," adds Raffo. "He’s only now getting to the good part, seeing what his artform can do."

The Environmental Consequences Of A Wall On The U.S.-Mexico Border On Jan. 25, President Trump signed an executive order instructing construction to begin on a wall along the U.S.-Mexico border. Environmentalists and civil rights activists say the proposed wall on the southern border with Mexico is a threat to the environmental rights of the people who live on both sides of the border. "When you have such beautiful wilderness areas as we have here in Arizona, the idea of putting this large wall that prevents the migration of animals, that scars the earth itself, and especially knowing how ineffectual it is, is something that is just sad," said Juanita Molina, the executive director of Border Action Network, an organization that advocates for the health and wellness of people who live along the border. "The reality is that border communities are porous by nature." Molina, who lives in Benson, Ariz., said the wall could cause flooding and debris build-up on both sides of the border. (Chris Clarke of KCET has reported that a concrete wall "would cause catastrophic flooding in the desert.") Molina also said there could be legal and ethical consequences if people try to build on the land of the Tohono O'odham Nation, whose reservation straddles the border, and whose leaders have spoken out for years against a border wall. But even if no part of the wall materializes, she said, the rhetoric around it has already caused rifts in her community. "I think that there's a polarization that's happening in our communities now that hasn't happened in many years," Molina said. "The mistrust and the racial divides are very present...This isn't the first time that the establishment hasn't supported our views as a community or supported our views as people of color...Our laws, our freedoms, our cultural evolution is something that is part of our everyday lives and struggle." As of 2010, there were about 15 million people living in border counties on both sides of the Mexico-U.S. border, according to the Wilson Center's State of the Border Report. If growth rates stay the same, the report says, that number is likely to reach 29 million in 30 years. In the four border states on the U.S. side, Texas, California, New Mexico and Arizona, people of Mexican origin make up at least a quarter of the total population, with higher concentrations in counties within 100 kilometers of the divide. In El Paso, Texas, for example, Latinos, primarily of Mexican descent, make up more than 80 percent of the population. According to Raul Garcia, who works at the environmental justice law firm Earthjustice, it's no accident that the border wall would primarily affect people of color. "With Trump's militarization of the border, he's specifically targeting immigrants and Latinos trying to make a life for themselves and their families," Garcia said. He said that communities of color all over the U.S. face similar challenges. Garcia pointed to issues like the water crisis in Flint, Mich., and construction of the Dakota Access Pipeline in South Dakota, where other communities of color have been singularly affected by environmental issues. "We also see it throughout our country when highways are built and minority communities, like Latinos and blacks, are divided and displaced to make way for the privileged upper class folks on the other side of the city," he said. Ira Mehlman, of the Federation for American Immigration Reform, supports the construction of the wall and said that it is an important tool for impeding illegal immigration. He said that FAIR supported the Secure Fence Act in 2006, which authorized construction of a border barrier — legislation, he pointed out, that had support from people like Hillary Clinton, Chuck Schumer and Barack Obama. In terms of environmental risks, Mehlman said that while a wall could have some environmental impact, "so [do] tens, hundreds of thousands trampling across the flora, leaving tons of garbage and debris along the way. So having that traffic is also damaging to the local ecology." But scientists and environmentalists have been warning about the potential negative environmental effects, like restricted animal movement and plant pollination, of a border wall for over a decade, since President George W. Bush signed the Secure Fence Act of 2006. When Donald Trump started discussing the construction of a full-scale border wall during his presidential campaign, those concerns resurfaced. In September 2016, Sergio Avila-Villegas, a conservation scientist at the Arizona-Sonora Desert Museum, told BBC's Science in Action team that "Border infrastructure not only blocks the movement of wildlife, but... destroys the habitats, fragments the habitats and the connectivity that these animals use to move from one place to another." George Frisvold, a professor at the University of Arizona who specializes in environmental policy, said that politically speaking, a border wall "gives this false impression that you're actually doing something, but it has this political attraction because it's completely ineffective" in preventing problems associated with immigration. Environmentally, he said, "Any time you're going to put big structures along the border, and usually it isn't just the structure out there by itself — you have to have some sort of access road for people to go get to it, so you're going to be tearing up natural habitat with structures and roads, and that's going to be disruptive." Mark Magana, the president of GreenLatinos, said he sees Latinos, especially millennials, becoming more involved in the environmental rights movement. He said many Latinos were raised to be cultural conservationists. "[We] grew up respecting, conserving, reusing, re-purposing, being very respectful for what we have," he said. "And that is not because I read about it or...I claim to be an environmentalist. It's because that's what our grandmother taught us...You know, 'Don't turn on the air conditioning. Reuse that piece of aluminum foil...Eat every part of the animal...Find a way to fix that.' "And we have, whether it's because of an agrarian ancestry or because of poverty, many cultures like Latinos have developed this natural culture of conservation. And it's just a respect we have for the little that we have." Earlier this month, Congresswoman Michelle Lujan Grisham introduced the "Build Bridges Not Walls Act," which would prohibit Trump's executive order. So far, it's been endorsed by 59 members of Congress and the Congressional Hispanic Caucus.

A mobile ad hoc network (MANETs) has become necessity in today's world. It has significant advantage when it is compared to the structured based network. Due to high demand of MANET, its performance is considered prior during implementation. Performance of MANET depends upon life time of network which further depends on various parameters such as, energy, mobility, density security of the network. Since MANET is powered with battery power which is always limited, thus building a power saving network is always a prime task. In this paper we proposed a strength based energy efficient algorithm where we calculate the energy of the node and the divide the tasks according, so that the maximum energy of the node can be saved and life time of the network can be enhanced. © 2015 IEEE.
