New Delhi: The sports fraternity on Friday came out in support of Mahendra Singh Dhoni for wearing the dagger insignia on his wicket-keeping gloves during India’s World Cup game against South Africa, with Sports Minister Kiren Rijiju urging the BCCI to resolve the issue. During the match in Southampton on Wednesday, Dhoni’s green keeping gloves had a dagger logo embossed, which looked more like an Army insignia. While his gesture was appreciated by fans, the ICC requested the BCCI to ask Dhoni to remove the sign from the gloves, citing rules that forbid display of messages “which relate to political, religious or racial activities or causes”.

I urge the BCCI to take a fair step in the Mahendra Singh Dhoni’s case,” Rijiju wrote on his Twitter handle. Dhoni also received support from Chennai Super Kings teammate and India batsman Suresh Raina, former pacer R P Singh, London Olympics bronze medallist wrestler Yogeshwar Dutt and India sprinter Hima Das.

It should be taken as an act of patriotism & not nationalism,” Raina tweeted. Yogeshwar, who won two gold medals at the 2010 and 2014 Commonwealth Games, said removing the logo will be an insult to the Indian Army. “The demand for the removal of this badge #ICC is not only an insult to the sacrifices of the Indian Army but the Indian Army. We all have fellow countrymen with Dhoni. #DhoniKeepTheGlove @msdhoni @ICC @BCCI,” he wrote. Hima, who is the first Indian to win a gold in a track event at the IAAF World U20 Championships, also threw her weight behind Dhoni. “INDIA with Dhoni brother. I support Mahi brother. Jai hind Jai Bharat…,” she wrote on her Twitter handle. R P Singh, too, was left bemused by the ICC’s stance on the issue. “Tough for me to understand how @msdhoni’s on field gesture on his glove is a problem to @ICC. His fans have taken inspiration out of it and he himself is a respected Lt.Col, really strange.#MSDhoni.”
9 September 2009The death of an Afghan interpreter who was killed during a rescue operation to free him and New York Times journalist Stephen Farrell from Taliban captivity highlights the dangers faced by media professionals working in the country, the top United Nations envoy there said. Gunmen reportedly seized Mr. Farrell and Sultan Munadi on Saturday while they were working in a village south of Kunduz in northern Afghanistan. “Sultan’s death is a tragic reminder of the dangers faced by media personnel working in Afghanistan, often in circumstances of considerable personal risk,” Secretary-General’s Special Representative Kai Eide said in a statement issued today in Kabul.Mr. Eide appealed to local authorities and insurgent groups alike to respect the rights of journalists to go about their work. “Media personnel, whether Afghan or foreign, should not be obstructed in the carrying out of their lawful and professional duties and should be treated as neutral and independent actors. “Above all, their safety must not be placed in jeopardy,” he stated.
15 October 2009United States actress Mia Farrow and Egyptian actor Mahmoud Kabil, both UN Children’s Fund (UNICEF) Goodwill Ambassadors, today ended a two-day visit to Gaza where they witnessed first-hand the hardships children still face nine months after the three-week war between Israel and Hamas. United States actress Mia Farrow and Egyptian actor Mahmoud Kabil, both UN Children’s Fund (UNICEF) Goodwill Ambassadors, today ended a two-day visit to Gaza where they witnessed first-hand the hardships children still face nine months after the three-week war between Israel and Hamas. “The children appear traumatized,” Ms. Farrow said. “The teachers say that when they hear a loud noise they look to the sky and cry out and weep. They don’t know what the future holds. They deserve better.”The fighting killed more than 1,400 people, including at least 350 children, and injured over 5,000 people, among them 1,600 children.Ms. Farrow entered from Israel through the Erez crossing point while Mr. Kabil crossed over from Egypt at Rafah to meet up in Gaza, which has been under virtual blockade for 28 months.They heard testimony from children who are now forced to work in tunnels to support their struggling families. The tunnels are used to smuggle in goods that are otherwise unavailable in Gaza. Unemployment rates are above 40 per cent and eight out of 10 families in Gaza rely on some form of food assistance.Ms. Farrow’s visit is part of a week-long trip to the occupied Palestinian territory and Israel, where she is meeting with officials, civil society organizations and children affected by conflict. She will go to Sderot in southern Israel which has been the target of rocket attacks from Gaza.For Mr. Kabil, this is the second leg of a journey to the occupied Palestinian territory. He was in the West Bank during the month of Ramadan to show support for Palestinian children and families during the holy month.“I am happy to finally be able to visit the children of Gaza and express my solidarity with their families for the suffering they are enduring on a daily basis,” he said. “The blockade and the recent fighting have left an indelible impact on children. Palestinian children have the same rights as all children everywhere and these rights need to be upheld.”
He also requested all staff to redouble their efforts and rededicate themselves to serve the motherland with commitment, determination and steadfastness. The Ambassador also emphasized the importance of keeping members of the Sri Lankan community engaged at all times with a view to promoting Sri Lanka’s image and interests in the host country. Speaking on the occasion, Ambassador Rodney Perera thanked the staff for the warm welcome and expressed his optimism that the relations between the two countries would be further strengthened and expanded encompassing all conceivable areas of interest during his tenure. Ambassador – designate of Sri Lanka to the United States of America, Rodney Perera assumed duties at the Embassy of Sri Lanka in Washington DC. Prior to appointment as the Ambassador to the US, Ambassador Perera was Sri Lanka’s Ambassador to Belgium, Luxembourg and the European Union. Upon arrival at the Embassy in Washington DC, Ambassador Perera was welcomed and greeted by the staff. His assumption of duties was marked by a simple ceremony which commenced with the lighting of the ceremonial lamp by the Ambassador and other diplomatic staff and traditional Sri Lankan milk rice and sweet meats being served on the occasion. Ambassador Perera, a member of the Sri Lanka Foreign Service for over three decades, held senior posts in Sri Lanka Missions abroad and in the Ministry of Foreign Affairs. He held the post of Additional Secretary and was the Ministry Spokesman from 2013 – 2014. Ambassador Perera also served as Sri Lanka’s Ambassador to Norway from 2009 to 2012 and to Italy from 2003 – 2007.Ambassador Rodney Perera holds a Master’s Degree in International Relations from Columbia University, New York. He is also the recipient of “Grande Ufficiale – Ordine Della Stella Della Solidarieta” (Grand Officer of the Order of the Star of Italian Solidarity – highest Italian civilian honor), bestowed by the President of the Italian Republic in May 2007.

Credit: Alyssia Graves | Assistant Sports DirectorThe South Florida women’s basketball team gave No. 13 Ohio State a hint of what was to come for the rest of the Sunday afternoon’s game in the first quarter. The Bulls jumped out to a 31-13 lead by the end of the opening quarter behind 18 points from junior guard Kitija Laksa.The Buckeyes pulled back within 12 points at the beginning of the third quarter, but could not complete a comeback and fell 84-65 to South Florida to end their four-game win streak. Ohio State has lost four of its past eight games.Laksa made 15-of-27 shots, including 8-of-13 3-pointers, and scored 41 points, nearly half of her team’s points. Maria Jespersen aided her, dropping 20 points and grabbing 14 rebounds. Just two players scored more than eight points, despite South Florida scoring 84 points. Senior guard Laia Flores added 11 assists.South Florida shot 46 percent from the field, compared to Ohio State’s 42 percent shooting. The Bulls did most of their damage from beyond the 3-point line and on second-chance opportunities.The made 11-of-22 3-pointers, while the Buckeyes shot 6-for-20 from 3-point range. The Bulls outrebounded Ohio State 46-26 and grabbed 15 offensive rebounds. South Florida had 17 second-chance points. No Buckeye had more than six rebounds, including redshirt forward Stephanie Mavunga, who averages a double-double.Mavunga kept Ohio State in the game offensively, though. She went 13-for-16 from the field, scoring 28 points. Mavunga also blocked four shots.No other Ohio State player managed to deal much damage offensively. The rest of the road team shot 13-for-45 and scored a combined 37 points. Senior guard Kelsey Mitchell scored 19 points, but hit just 6-of-15 shots and went 2-for-8 from beyond the arc.

Ohio State turned the ball over just six times, but forced the Bulls into 11 turnovers.
Two of the closest galaxies to our Milky Way—the Large and Small Magellanic Clouds—may have once had a third companion.New research describes a tertiary galaxy probably engulfed by the Large Magellanic Cloud some three to five billion years ago.Most stars in the Large Magellanic Cloud (LMC) rotate clockwise around the center of the galaxy, according to the International Center for Radio Astronomy Research (ICRAR).But some appear to move counter-clockwise.“For a while, it was thought that these stars might have come from its companion galaxy, the Small Magellanic Cloud,” ICRAR Masters student Benjamin Armstrong, lead author on the study, said in a statement. “Our idea was that these stars might have come from a merger with another galaxy in the past.”Large Magellanic Cloud photographed using a small telephoto lens and a modified DSLR camera to highlight the molecular clouds (via Andrew Lockwood)Two irregular dwarf galaxies less than 200,000 light-years from the Milky Way, the Magellanic Clouds can be seen in the night sky with the naked eye.Until the discovery of the Sagittarius Dwarf Elliptical Galaxy in 1994, these were the closest known galaxies to our own. The Canis Major Dwarf Galaxy, spotted in 2003, is considered the actual nearest neighbor.Armstrong, based at the University of Western Australia, used computer modelling to simulate galaxy mergers.“What we found is that in this sort of merging event, you actually can get quite strong counter-rotation after a merger takes place,” he explained. “This is consistent with what we see when we actually observe the galaxies.”In collaboration with ICRAR principal research fellow Kenji Bekki, Armstrong uncovered evidence that could help answer the long-standing question of why stars in the LMC are either very old or very young.An inverse luminance image of the large and small clouds (via Andrew Lockwood)Galaxies’ star clusters contain “many, many, many stars”—typically of similar ages, made in similar environments. The Milky Way, for example, features clusters that are all very old.The LMC, however, has an array of very old and very young clusters—with nothing in between—creating an “age-gap” problem.“Because in the Large Magellanic Cloud we see star formation starting again, that could be indicative of a galaxy merger taking place,” he said.It could also explain why the LMC appears to be surrounded by a thick disc.The research—intended as a “new way of looking at an old problem”—is detailed in a paper published by the journal Monthly Notices of the Royal Astronomical Society.Earlier this month, astronomers were able to detect radiation from cosmic rays in the Large and Small Magellanic Clouds. Scientists also captured super-sharp images of celestial bodies using the Very Large Telescope’s adaptive-optics module.

Clark County will soon have an interim county manager.At its Wednesday afternoon board time meeting, the Clark County council voted 4-0 (Councilor John Blom was absent) to approve an agreement with the Prothman Co., an Issaquah-based consulting and recruiting firm, to provide the services of Jim Rumpeltes as interim county manager.Under the agreement, Rumpeltes, who has a background in government management in Arizona and Washington, will not be an employee of the county but instead of the Prothman Co. Speaking after the meeting, Deputy County Manager Bob Stevens said that the county will pay Prothman $125 an hour for services provided by Rumpeltes.He said July 10 will be the target start date. He also said that the agreement does not include payment for benefits and is open-ended with no termination date. During the meeting, Stevens noted that the council could negotiate a separate housing allowance with Rumpeltes. He said that the money could come out of a leftover vehicle allowance for former Clark County Manager Mark McCauley that was not included in his severance after he was suddenly terminated from his position in May.“As for the total contract costs, we don’t know,” said Stevens, in response to concerns expressed by Councilor Jeanne Stewart about the costs of the agreement. “It depends on how long we have him. It will essentially be ($5,000) a week just for the services that we pay Prothman for, assuming a 40-hour week.”When reached by phone, Rumpeltes declined to comment, saying he hadn’t heard anything from the county. According to his résumé, Rumpeltes worked as budget director for Spokane County between 1978-1985 and as county administrator for Clallam County between 1986-2001. He later served as assistant city manager and city manager for Surprise, Ariz., a city of about 132,000 in Maricopa County, between 2001-2008. Additionally, he’s done short-term work with other cities in Arizona and Waste Management Inc.
The Girls’ Agenda, a young women’s led organization in The Gambia that champions the rights and wellbeing of girls and women will host a five days empowerment camp for girls. The camp, funded by UNICEF will target fifty (50) young women between the ages of 14 and 24 in the West Coast Region. The empowerment camp is on the theme Progress for Adolescent Girls Require the Guarantee of their Sexual and Reproductive Health Rights, and will be held from the 10th to 14th February, 2017 at the Child Fund Lodge in Bwiam.The five days intensive camp will focus on issues that affect the young women’s well-being which includes their right to bodily integrity, progress, liberty and freedom. The empowerment forum will cover an intensive introduction to comprehensive sexuality education, life skills including leadership skills learning, education and mentorship for girls, harmful traditional practices (with a focus on early marriage and female genital mutilation/cutting), sexual violence and related matters.Female genital mutilation and child marriage remain some of the most pervasive human rights violations that undermine girls’ well-being, bodily integrity, an opportunity to education and self-reliance. In Africa alone, millions of girls are at risk of undergoing these harmful practices because of a patriarchal culture that controls women’s sexuality and bodies. Although The Gambia recently created a law that prohibits FGM, its widespread acceptance obviously will lead to the secret performance of the act on minors many women’s rights organizations observed. Therefore, The Girls’ Agenda feel that behaviour change towards FGM and all other forms of degrading treatments should be a combination of social denouncement and a legal approach. To achieve this, there is no better and sustainable approach than teaching and engaging young people to lead the change that will end inequality, discrimination and degrading treatment of women and girls. With this camp, we hope to revolutionize the demand for the respect and protection of the sexual and reproductive health rights of women and girls, fight to end disparities in education, build healthier and empowered adolescent girls and the eradication of harmful traditional practices in our communities. The camp will help raise awareness of young women about the factors responsible for the perpetuation of FGM, clarify misconceptions that support the practice, show them the evidences/consequences of FGM (which are often kept as secrets or misinterpreted) and prepare them to become change agents through organizing, lobbying and advocacy skills. We hope that this camp will empower the girls- both socially and politically and enable them use their voices and work towards ending FGM and related discriminated practices in our generation. We believe that the world will become a better and progressive place if girls are able to speak for themselves to end violence and inequality in every home and community. The Girls’ Agenda Team
In a release from Katmai National Park, the group violated National Park Service wildlife viewing regulations, putting themselves and wildlife at risk. Immediately after the incident, Katmai rangers received multiple reports from concerned visitors and explore.org bear cam viewers who observed the violations.The group was contacted by park rangers and charges are pending. Details on identities will be released when charges are finalized. Facebook0TwitterEmailPrintFriendly分享Two Alaska residents and one out of state visitor entered a closed area below Brooks Falls approaching multiple bears that were actively feeding on a concentrated food source, on August 9, at 6:50pm. Mark Sturm, Superintendent: “People need to recognize that these are wild brown bears. These visitors are lucky that they escaped the situation without injury. The possible consequences for the bears and themselves could have been disastrous.” In Katmai, approaching within 50 yards of a bear using a concentrated food source, like migrating or spawning salmon, is prohibited. Because of concentrated bear activity at Brooks Falls, area closures are in place from June 15 through August 15, in order to allow bears access to essential food resources that allow them to survive through the winter.
Twitter The GRAMMY Museum provides K-12 students the opportunity to dive deep into music with its programs and camp. This Giving Tuesday, the Museum is asking for your help to continue bringing these resources to them Jennifer VelezGRAMMYs Nov 27, 2018 – 5:00 am The GRAMMY Museum is home to one-of-a-kind music exhibitions and experiences that bring its visitors closer to the artists and music they love. On Giving Tuesday the museum is asking for your help to support the music education programs they provide, in order to continue bringing music access to students in and out of the classroom.Throughout the year, the museum seeks to give underprivileged communities access to music education and prepare K-12 educators with resources to show the power of bringing music to the classroom. Over the next 24 hours, the GRAMMY Museum has set out to raise $50,000 to continue providing students with tools and resources they need to explore music education.Past programs include a workshop on the how music has been a catalyst for change throughout wars, including the Civil War and World Wars I and II, as well as lyric writing workshops. The museum also offers tours for local schools and organizes a camp for young aspiring musicians in high school. These student-centered programs help support the museum’s mission of using “music as a gateway to learning; inspiring and cultivating creativity, critical thinking and self-expression.”Teachers and parents have seen students positively engage with the programs. Larchmont Charter School teacher Dave DuMonde shared how excited his students were after their visit to the museum.”They were fully inspired—a new passion has been sparked in our music program,” DuMonde said. “I received a resounding response from parents saying how cool and unique of a trip it was. Thank you, thank you for accommodating our group of 5th and 6th graders!””As I looked around during the performance, the children were all engaged and paid close attention to the action on the stage,” said one teacher who would like to remain anonymous. “In this day and age of budget cutbacks in the Arts Programs in our school systems, programs such as this are MUCH NEEDED.”According to the museum, a donation of $500 provides a whole class of students bus transportation for a visit to the museum in downtown Los Angeles. A visit to the museum deeply shaped Janet L. Jackson’s daughter’s musical aspirations.”My daughter left the GRAMMY Museum after her first visit and declared she wanted to be a rock guitarist,” Jackson said. “That year she got a guitar for Christmas and has been taking lessons ever since.”The GRAMMY Museum also puts on a GRAMMY Camp in which high school students learn more about careers in the music industry, including songwriting, audio engineering, music journalism, instrumental performance and more.”Attending camp really pushed me to work harder and study more about production. I’ve just finished producing a five track EP, and I’m now learning about licensing, distribution, and advertising. I don’t think any of this would have happened if I hadn’t been given this opportunity and attended GRAMMY Camp,” GRAMMY Camp alum Markus said.For more information on how you can support the music education the GRAMMY Museum brings to students visit the GRAMMY Museum’s donation page.GRAMMY Camp—Weekend Brings Music Career Training To PittsburghRead more Email Facebook News Giving Tuesday: The GRAMMY Museum Needs Your Help Supporting Music Education Support The GRAMMY Museum This Giving Tuesday giving-tuesday-grammy-museum-needs-your-help-supporting-music-education
Alaska’s capital city is battling addiction. The Juneau community continues to face substance-related deaths and near deaths.Three women tell their stories about addiction, long-term recovery and a rally that gave them hope.Download AudioAlaskans were part of the UNITE to Face Addiction Rally in Washington, D.C.: (left to right) Kim Whitaker, Julee Douglas, Samantha Garton, Terria Walters, Kara Nelson, Delia Williams, Jennifer Mcallister and Christina Love inside a congressional office building in D.C. in October. Nelson is holding a picture of Christopher Seaman, the son of Walters who was murdered in Mat-Su in June. (Photo courtesy Kara Nelson)Christina Love, Kara Nelson and Julee Douglas are all in recovery. At different times in their lives, they’ve been addicted to different substances.Love is an advocate at the AWARE shelter in Juneau. She said her addiction started out with Adderall in college. Cocaine was next.“Then we went to crack cocaine, and alcohol is always there. The hangovers were bad, so we went to pills, then we went to oxys, and then we went to heroine, and then benzos. And really it’s anything that’s in front of you at any given point,” Love said.Love detoxed in Fairbanks and became sober. Then she started treatment and is in long-term recovery.“Once you have this disease, you suffer it for the rest of your life, and it can’t be stopped,” Love said. “But it can be arrested.”Love and Kara Nelson met on the recovery journey about four years ago. They’d been anonymous in meetings held in churches and basements before they started speaking and advocating publicly.Last month, they and six other women from Juneau and Anchorage represented Alaska in the UNITE to Face Addiction Rally in Washington, D.C. They marched in the National Mall with close to 30,000 people involved in the recovery movement, including other recovering addicts and those who’ve lost people to addiction.Nelson is the director of Haven House, a faith-based transitional home for women recently paroled or released from prison. Haven House provides peer-to-peer support for women who’ve faced addiction and incarceration. She organized the trip to D.C.“As a person in long-term recovery and as someone who has an extensive history in our criminal justice system and continuously sees my friends, our neighbors, our people incarcerated and then the effects of that and then getting out and having even more issues than being in prison itself, this was a very personal thing for myself to be a part of,” Nelson said.The rally was aimed at changing the conversation around addiction and treating it as a health crisis. Nelson said recovery is a lifelong journey, not aftercare for a month.“If you have any other kind of illness or disease, you’re going to have these check-ups and you’re going to continuously be checking in to every symptom, right? That’s exactly how substance use and mental health should be treated as well,” she said.At one of the rally events, people wore T-shirts and carried posters with photos of loved ones who had passed away from addiction. Julee Douglas said being surrounded by that helped her and the others come to terms with the wreckage of their past.“Any one of us could have been a poster or a T-shirt for sure,” Douglas said.Douglas also works at Haven House as the house manager. She said offering peer support to the residents gives her support to heal from her alcohol addiction.During the rally, the group visited Alaska’s congressional delegation to lobby for bills related to the recovery movement, like theComprehensive Addiction and Recovery Act. The CARA bill will help bring money to grassroots recovery organizations.Love said it was empowering to be at the D.C. rally and advocate with people who share experiences of feeling rejected, discriminated against and suicidal.“I’ve said a million times over and over, ‘I’m a person in long-term recovery.’ That’s one of my favorite things about myself and it’s one of my favorite things about the people that I help because it stands for something so completely opposite from what the rest of the world thinks,” Love said. “They see an addict, but I see a person who’s resilient and a fighter.”Nelson helped form the Juneau Recover Community two years ago. It’s people in recovery helping others through support and social events, like Recovery Fest. But she says more needs to be done.“We’ve been able to educate ourselves to really be in a position where we are the ones that are the solution.”Nelson and Love, both recovery coaches, plan to work with local agencies to form a community plan focused on recovery, and are actively meeting with Juneau organizations to try to establish a detox facility.

But R. Dean Astumian, a Physics Professor at the University of Maine, has recently proposed a concept in which molecular machines can operate arbitrarily close to chemical equilibrium at every instant of the cycle, and still perform work at the rate of several micrometers per second against piconewton loads. The study, “Adiabatic operation of a molecular machine,” is published in a recent issue of the Proceedings of the National Academy of Sciences.“The main significance is conceptual – it changes the way we think about molecular motors,” Astumian told PhysOrg.com. “Much emphasis has been put on the ‘non-equilibrium’ aspects of the system, but in fact this is not really important. The motion of the rings here arises due to a combination of topology that break spatial symmetry, and the slow external modulation that breaks time symmetry. It is also important to recognize that, in the molecular world, we can truly have motors that operate with nearly 100% efficiency.”Astumian’s example of such a molecular machine is a three-ring “catenane” structure that serves as a rotating motor. The catenane, about 3 nanometers in diameter, consists of one large ring with two smaller rings linked to the large ring, like rings on a keychain. Three binding stations on the large ring provide locations where the two small rings can bind, depending on the interaction energy between ring and station. Astumian gets the small rings to move clockwise from station to station around the large ring, a movement that results in mechanical cycling. Further, he achieves this movement without any heat gain or heat loss and without a change of entropy, but simply by thermal noise due to Brownian motion. This type of “adiabatic” system is arbitrarily close to equilibrium at every point of the cycle.The key to making the small rings move from station to station is by periodically modulating the interaction energy. The rings will bind to the station that requires the lowest interaction energy. This modulation must be done slowly enough not to generate heat, but at a sufficient rate to produce significant work. Slowly modulating the energy of a single molecule is challenging, and Astumian explains that it is nearly impossible to do with chemical systems. However, the net interaction energy for many molecules can be slowly modulated by very slow titrations of pH and redox potential. For example, a condition that is strongly acidic and strongly reducing corresponds with high interaction energy at station 2. Therefore, the two rings will bind at stations 1 and 3. Explore further Molecular machines – tiny machines made of molecules that do mechanical work – are usually thought to operate in a state of non-equilibrium. This makes sense, considering that macro-sized machines operate at non-equilibrium, requiring an additional force to move. On the other hand, equilibrium implies that forces cancel each other out, resulting in an unchanging system, often at rest. Then, by titrating with oxidant to reach a strongly oxidizing and strongly basic condition, the energy at station 1 is highest. So the rings now occupy stations 2 and 3. Astumian explains that the rings could switch to this state by either the ring at station 1 moving clockwise to bind at station 2, or the ring at station 3 moving counter-clockwise to bind at station 2. However, after more modulations, the majority (about 75%) of the movements will be clockwise due to the changing energy levels at different stations. By figuring this probability, Astumian concludes that, every time the small rings move around the large ring, the system will complete one-half of a mechanical rotation.He also mentions that there might be more creative architectures where counter-clockwise motions don’t undo the clockwise motions. He likens this mechanism to a ratcheting screwdriver used to drive a screw. When the ratchet turns counter-clockwise to reset itself, it releases so that it doesn’t undo the forward turn of the screw. Although a molecular machine would use thermal noise instead of external torque, the concept is similar. In the molecular machine, one of the small rings could be fixed to prevent counterclockwise motion.“I would say that the biggest challenge is to arrange the molecules on a surface so that the movement can be used to do work on the outside world,” Astumian said. He added that the chemical structures have already been synthesized by David Leigh at the University of Edinburgh, as the next step in the development of the machines.Astumian also explains that operating this system requires a fine balance between modulating slowly enough so that the system is in chemical and mechanical equilibrium at every instant, but rapidly enough to perform substantial work. While biomolecular motors are often described in “violent” terms, he hopes that this “kindler, gentler” description may be more appropriate for designing more efficient molecular machines.“I plan to extend the theory to explain the mechanism of biological motors,” Astumian said. “While they doubtless do not operate exactly by the mechanism described for the three-ring catenane, I think the flavor of how they operate is much better characterized by this near-equilibrium description than by various biological models involving cars, judo throws, and steam engines.”More information: Astumian, R.

Brindisi and other cities over the weekend were commemorating the 20th anniversary of the killing of the Falcones, leading to one possible hypothesis that organized crime carried out the school blast.The blast _ caused by the explosion of canisters of fuel apparently left in or near a trash bin by a school gate _ revived dark memories for many Italians of the 1970s and 1980s, when terrorists, anarchists and organized crime outfits carried out dozens of bloody attacks across the country.Italy’s justice minister, Paola Severino, said no motive has been ruled out in the probe of the blast, which is in the hands of a team of prosecutors specializing in organized crime and terrorism cases. Brindisi police said no one has been detained in the case.The bombing follows a spate of attacks against Italian officials and government or public buildings by anarchists, including the shooting and wounding of an official from a nuclear engineering firm, which is part of a state-controlled company. An anti-nuclear anarchist group that previously had targeted Italy’s tax collection agency claimed responsibility for the shooting. ROME (AP) – Italian Premier Mario Monti on Monday embraced the grieving father of a 16-year-old girl who was killed by a bomb blast outside her school in southern Italy.Monti left the NATO summit in Chicago a day early to attend the funeral of Melissa Bassi near Brindisi. A bomb exploded just as Bassi and other students were arriving for class Saturday at a vocational high school in the Adriatic port city.Bassi’s father clutched a photograph of his daughter to his chest and appeared inconsolable as Monti embraced him. The victim’s mother, still in shock from her loss, didn’t attend the church ceremony. Four other girls are hospitalized for severe burns and other wounds.
Source = e-Travel Blackboard: K.W Amadeus Offers has been described as a ‘first of a kind solution’ that will save travel consultants time in the management of pre-booking activities, quote handling, proposing alternatives and making and cancelling provisional bookings. Launched yesterday, the travel technology partner and transaction processor for the global travel and tourism industry, Amadeus, has revolutionised the way consultants work by using the GDS to automate the quote generation and conversion process. Utilising Amadeus Selling Platform, one of the most widely used front office application, Offers creates professional, easy-to-read offers that automatically include flight and hotel itineraries, pricing and mini-fare rules. Once generated, travel consultants then can easily email the quote to the traveller in a selected format to suit or through Amadeus online portal Checkmytrip. Also once the client confirms to book, the conversion from a quote to a booking can be done in a single transaction, avoiding the need to perform the entire search flow again. Consultants can instantly retrieve the offer from the PNR (searching by name or booking reference) and validate the fare and costs before converting it into a booking. As no airline inventory is held, there is no need to cancel rejected offers, which automatically expire after 30 days. “Amadeus Offers is a revolution for travel agents,” Amadeus IT Pacific managing director Sari Vahakoski said of the time saving solution that helps to improve customer service and agency ability to report on pre-booking trends. “It provides a central, cross-channel facility to manage pre-booking functions and can store up to 20 saved quotes, or offers, inside a single easy-to-retrieve Amadeus Passenger Name Record (PNR). “It will help travel agents to dramatically improve operational efficiency and boost revenue – a must have for travel agents in Australia, New Zealand and the Pacific Region.”

counties in an early funding bill They say such a bill won’t be needed again if their other proposal of giving oil counties 60 percent instead of 25 percent of oil production tax is successful"I think we need to understand how the past money we’ve sent has been spent" House Majority Leader Al Carlson R-Fargo saidCarlson said funding for west North Dakota will undoubtedly be a dominant topic next session He said there will be more money going west and that the surge funding and revamped tax formula are good proposals to start with He wasn’t surprised by the poll resultsDunn County Commissioner Daryl Dukart said he wasn’t surprised by the poll results either as he’s visited with many legislators who have traveled to see the west’s needs for themselves"They see and understand the problem and the situation It’s probably more the situation of making their constituents understand that there is a definite need out here too" he saidFor the most part regardless of political party or geographical region a minority said the west gets enough funding — 208 percent of Republicans and 174 percent of Democrats and 175 percent of eastern North Dakotans compared to 196 percent of westerners Senate Minority Leader Mac Schneider D-Grand Forks said in his district constituents understand the need to "stand shoulder-to shoulder with western North Dakota" as it weathers this "very welcome" economic activity and growth"There’s a myth out there that the east doesn’t want the oil counties to take care of their infrastructure" Wardner said "and that’s not true"Environmentally soundNearly half or 464 percent of respondents said they are either very or somewhat satisfied that oil production in the state is environmentally soundDon Morrison executive director of environmental group Dakota Resource Council predicted that more respondents from severely oil-impacted areas would lead to more reporting concerns over the environmental safety of the production"I would expect those who live in the west are more knowledgeable about how it’s being regulated because more people are being dissatisfied because they are living with the impacts of some pretty lackadaisical enforcement of North Dakota laws" he saidNorth Dakota Department of Mineral Resources spokeswoman Alison Ritter pointed out 42 sections of code were changed last session and 22 were changed the session before that"I think rulemaking has been pretty responsive but also I guess flexible in order to allow for industry to still operate in the state" she saidWardner said he wasn’t surprised by the results including a big divide between Republicans and Democrats and said he expects regulation to be an issue in political races and the sessionDukart said from what he sees on the ground in Dunn County some regulations are up to par and some aren’t Minimizing the footprint oil development leaves on the surface of land is one issue that needs to be addressed more he saidSchneider said he isn’t a fan of more regulations for the sake of having more but did highlight what he sees as a conflict of interest within state law — that Department of Mineral Resources Director Lynn Helms is responsible for both promoting and regulating the oil industry"I don’t think more regulations are the answer but I do think addressing that inherent conflict would be a much better assurance of the outcome for North Dakota landowners" he saidMore respondents — roughly 59 percent — said they had concerns with the safety of crude-by-rail"I think we all have a little bit of concern" Wardner saidSome have proposed stabilizing Bakken crude before it’s loaded on to trains to make derailments and collisions less dangerous when they happen"There are problems with the trains and the tracks and the cars and I don’t want to minimize any of the problems that are due to the railroad but if those trains we’re carrying kids’ toys or furniture those 47 people in Quebec would still be alive" Morrison said referencing a deadly derailment of carloads of Bakken crude in Quebec in 2013While a majority of respondents 62 percent said they would support oil payments to every state resident out of tax revenues legislators said long-term investments with oil revenues are a more sustainable use of the funds"We’ve taken that surplus money and we’ve turned that back into educational funding and property tax relief and I think that is a better choice for using the money" Carlson saidSuch payments are prohibited by the state ConstitutionSchneider too suggested an endowment like for higher education in place of payments to every resident"I think most citizens would pick access to education for their kids over benefit checks for themselves" he saidThe poll has a margin of error of plus or minus 5 percent with 95 percent confidence and is based on landline and cellphone interviews of 505 randomly selected North Dakotans 18 and older who said they were likely to vote The surveys were
