‘Low tech’ light in neutron beam illuminates photosynthesis in bacteria

Čtvrtek, Září 29th, 2011

“It’s really low tech,” says Volker Urban, lead instrument scientist on the Bio-SANS, with a grin. “You can buy the parts anywhere.” The lighting tool is the work of graduate student Brad O’Dell, a visiting intern from Cambridge University in the United Kingdom. The device combines light emitting diodes with the electronics that drive the illumination.

Parts off the shelf it may be, but the device facilitates research into biologically inspired solar cell devices, important alternative energy-related research being conducted with funding from the Photosynthetic Antenna Research Center one of the Energy Frontier Research Centers in the US.

Photosynthesis is the process by which plants convert sunlight into energy. Bacteria, algae and plants have natural sensors called light-harvesting antenna systems that capture the sun’s light and transfer the energy to reaction centers, where the electron transfer for photochemistry occurs. Such antenna complexes are highly specialized in nature, allowing organisms to capture the maximum light energy available in their environment.

Researchers at the Bio-SANS are now using the new LED lighting tool to study the light response of the membrane stacks in cyanobacteria, a blue-green algae found in almost every environment, from oceans to fresh water to bare rock to soil.

At the Bio-SANS, the bacteria are loaded into cuvettes, small sample holders that resemble tiny transparent banjos. An LED is fixed to the top of each cuvette. The array is then pushed into the sample holder and the neutron beam passes through a window, taking “pictures” of the response of the layers of the bacteria to variations in light from the attached LEDs.

“We push the samples into the neutron beam - and then from the neutron scattering we can observe how the structure changes, depending on how much light of which color we shine on the samples,” Urban said. “Ultimately, we want to find out how nature has solved the problem of optimizing the efficient use of solar energy through these intricate architectures of antennas. These collect sunlight and funnel the light energy to reaction centers, where it is converted into chemical energy that can be stored for further use,” he said. “If those fundamental principles are better understood then they can be used to create new, more efficient solar panels.” They have already made some observations. “In a preliminary experiment, we could see with neutrons that the membrane stacking in the cycnobacteria changes in response to light on/ light off,” Urban said. “With this new light in place, we can now study this response more precisely, and in more detail: How does it depend on the intensity and the color of the light?”

Accused shouted at victim’s friend

Středa, Září 28th, 2011

Tom Kahl, 18, died at the scene on a country road in the middle of the night after crossing the road on his bike to join his friends.

They had set off to a nearby town to visit a friend at 11pm on July 10 last year, the jury heard.

Jonathan Ashworth, of Shipton-on-Cherwell, denies causing death by careless driving while over the alcohol limit.

The court heard he yelled: “What were you doing on the bike?” at Ben Fouracre, unaware the teenager was not the person he hit but was looking for his fatally-injured pal.

Ashworth, 55, said to police: “It wasn’t my fault. He didn’t have any lights.”

He was reported as smelling of alcohol and being unsteady on his feet, after bringing his Range Rover to a halt about 400 metres from the impact scene, the court heard.

Prosecutor Ann Evans told the jury: “Tom was cycling on the path on the right-hand side of the road.

“He had his iPod headphones on his ears, singing to his music. Ben Fouracre and Lewis Charlett were on the path on the other side of the road. Tom didn’t have any lights. He didn’t have high-visibility clothes.”

The trio was among a group of five travelling by bicycle from their homes in Kidlington along the A4260 to see a friend, named in court only as Georgina, in Woodstock.

Mr Fouracre, who had known the victim since they were both five years old, said: “Tom looked to the side where we were, looked at the car and crossed the road.

“He came over, saw he had a lot of time and literally in seconds the car was there.

“It was going so quickly. It was going way quicker than it should have been.”

The court heard the Range Rover struck Mr Kahl. Mr Fouracre said: “The car carried on going. It was a good 300-400 yards up. He did come back to us. He walked back towards us, shouting. He walked, didn’t run.

“He was shouting at me for being on the bike.”

Miss Evans told the jury at Oxford Crown Court a urine sample from Ashworth showed 112 milligrams of alcohol in 100 millilitres of urine, the limit being 107 milligrams.

Bashing the European Union in the United States

Úterý, Září 27th, 2011

Since the recession, bashing the European Union has become a sport for U.S. commentators. Just skim the most recent headlines, and one is led to believe that the old continent is on the brink of economic, political and social collapse. The truth is that very few commentators really seem to grasp the revolutionary character of the European Union — revolutionary because it successfully spreads the premises of the American Revolution, which Abraham Lincoln summarized in the Gettysburg address as “government of the people, for the people, and by the people.” The European Union’s promotion of a free market economy and democracy is one of the most underreported success stories in the U.S. media.

Enlargement of the European Union is perhaps the only time in history that sovereign nations have voluntarily submitted to conditions that usually only the vanquished, after a long, drawn-out conflict, would accept — adaptation of alien legislation ranging from new penal codes to energy intensive light bulbs, the relinquishing of key economic competencies, such as trade and monetary policy, and a common currency and tariff reductions.

The well-known Copenhagen criteria, the rules that define whether a country is eligible to join the European Union set forth by the European Council in June 1993, are criteria the U.S. founding fathers would have delighted in: stability of institutions guaranteeing democracy, human rights and respect for and protection of minorities; rule of law; the capacity to cope with competitive pressure and market forces, i.e. the establishment of a free market economy; and a very strict adherence to the aims of political, economic and monetary union.

Certainly, there have been various setbacks. For example, French President Charles de Gaulle used France’s veto and rejected British membership to the European Economic Community (as it was called in 1971) fearing the influence of the United States.

The French also opposed the membership of Greece, Spain and Portugal, countries that just emerged from dictatorships in the 1970s, because of the fear that they were not ready for democracy and the free market but eventually gave in, with the former acceding in 1981, the latter two in 1986. Today, Austria vehemently opposes Turkish membership. Romania and Bulgaria, countries that joined in 2007, still have a long way to go in protecting minorities and upholding the rule of law.

Magnalight by Larson Electronics Announces Addition of Pistol Grip Infrared LED Spotlight

Čtvrtek, Září 22nd, 2011

Larson Electronics’ Magnalight announced today the addition of the HL-85-3W1-IR Infrared LED spotlight to its available line of infrared LED lighting equipment. This handheld infrared LED spotlight can operate on any voltages ranging from 9 to 32 VDC and comes with an included 16 foot coil cord and cigarette plug to allow portable connection to most types of vehicles and equipment equipped with cigarette plug sockets. Extremely durable and capable of producing an infrared light beam reaching up to 1,800 feet in length, this IR spotlight is ideal for military and law enforcement applications using night vision equipment.

The HL-85-3W1-IR Infrared LED spotlight from Magnalight provides a powerful and effective infrared light source capable of illuminating objects up to 1,800 feet away. Available in 850nm and 940nm versions, this pistol grip LED spotlight is ideal for use with night vision equipment and produces enough IR illumination to discern details and identify persons at the far end of its range.

Designed for durability and high output, the housing on this unit is constructed from impact resistant nylon with a light head formed from machined aluminum with an unbreakable Lexan lens to protect the LED and reflector assembly. The 3 watt infrared LED in this unit is rated for over 50,000 hours of operation and produces an IR light beam approximately 1,800 feet in length by 175 feet in width. This light can operate on any voltage from 9 to 32 VDC and includes a 16 foot coil cord with cigarette plug, allowing the unit to be connected to most 12 volt civilian and 24 volt military vehicle and equipment electrical systems.

To meet these expanding markets we scaled down our larger infrared emitters, i.e. the LEDLB-80X2E-IR, into an easy to hold, easy to move, form factor that operators can bring to bear on large or small parts.”

New Orleans Saints sack Jay Cutler six times in 30-13 win over Chicago Bears

Středa, Září 21st, 2011

New Orleans’ defense held Chicago to 246 yards of offense and only 60 on the ground — 42 of which came on one run by Matt Forte on the Bears’ first-quarter touchdown drive. Saints coach Sean Payton said taking away the run allowed the Saints to keep pressure on Cutler.

“Once a team becomes one-dimensional … it’s challenging in our league,” he said. “When that little bit of threat of the run is removed, especially in an environment like this, that ends up being a recipe for a lot of hits.”

Brees’ bomb to Henderson was the big play of the first half. Chicago had opened the scoring with an 8-yard touchdown pass from Cutler to Dane Sanzenbacher and the Saints had cut the lead to 7-3 with the first of three field goals by John Kasay, a 31-yarder at the end of the first quarter.

But with the Bears in a Cover 2 on third-and-12, Henderson got behind the secondary down the middle of the field to haul in Brees’ pass in stride, slip a tackle and race to the end zone.

“I think Sean did a good job of calling that play at the right time, with that defense,” Henderson said of Payton. “And we took advantage of it.”

Kasay, who moved past Jason Elam into sixth place on the NFL’s all-time field goals list with 438, was good from 29 and 53 yards and Chicago’s Robbie Gould hit a 42-yarder on the final play of the first half, as New Orleans led 16-10 at halftime.

Gould added a 38-yard field goal early in the third quarter before the Saints’ defense turned the tables, as Turk McBride stripped Cutler and Jonathan Vilma recovered at the Chicago 29. Five plays later, Brees found Meachem in the end zone for the 4-yard score and a 23-13 lead.

“It was, I’d say, the big turning point in the game,” Brees said of McBride’s strip, “because it was in the second half and that’s when we wanted to establish ourselves and pull away.”

Brees then found tight end Jimmy Graham with completions of 13, 15 and 7 yards and Mark Ingram ran for gains of 12 and 8 before Sproles took a short pass and sprinted up the right sideline from 12 yards out to make it 30-13 with 12:05 to play.

The defense took over from there, as five of the Saints’ six sacks came in the fourth quarter, including two each by Junior Gallette and Roman Harper.

Henderson finished with three catches for 103 yards and the score. Ingram led the Saints on the ground with 51 yards on 14 carries.

Cutler was 19-of-45 for 244 yards and one touchdown for the Bears, who lost tackle Gabe Carimi and receiver Earl Bennett to injuries in the first half.

Forte was Chicago’s only consistent weapon, running for 49 yards on 10 carries and catching 10 passes for 117 yards as Cutler repeatedly checked down under pressure.

“It was a long day out there,” Cutler said. “I had to throw a lot of balls away before I wanted to. The Saints were the better team today.”

Tour of Duty: Vigus recalls adventures of 530th Army Engineers

Úterý, Září 20th, 2011

The subject of this installment in The Bulletin’s Tour of Duty series, W.H. “Bill” Vigus, is also author of a book titled The Travels and Adventures of The 530th Engineers Light Ponton Bridge Company, a personal remembrance of the company’s work. This story draws frequently from Vigus’ work.

W.H. “Bill” Vigus, 93, had a box seat for some of the biggest battles of World War II in the Pacific, but he got little time in that seat.

A motor pool mechanic with the 6th Army’s 530th Engineers Light Ponton Bridge Company, Vigus saw Japanese fighters and bombers shot down in numbers in such rapid succession they couldn’t be counted by a single observer during invasion of Leyte. He also helped keep the 530th running as it played a key role in laying down vital ponton bridges on Leyte and Luzon, at times in front of battle lines and often under fire.

On Oct. 20, 1944, liberty ships, S.S. Adoniram Judson and Clarence Darrow, carried the 530th in one of the Pacific war’s largest invasion forces to the shores of Leyte.

“The Filipino people met us in outrigger boats, bringing us bananas and coconuts. The Jap army met us in their zeros and Betty bombers bringing us bombs and machine-gun bullets. One group wanted to make us welcome and the other one wanted to blast us out of the water.

“The gun crew on the cargo ships did themselves proud with their shooting. The air was so filled with bursting shells that you could have walked on it. The Jap planes were being knocked out of the sky left and right. One man couldn’t have counted them all,” Vigus said.

Early in the shooting, the Darrow was apparently one of the first ships in the sights of two Betty pilots who flew out of the jungle at tree top level, dropping two torpedoes that seemed on course to hit the Darrow.

“Both planes dropped torpedoes that were aimed at us. It looked like we had made this trip in vain. The first one passed by our bow and exploded on the reef behind us, causing everyone at the bow to run to the stern. The other torpedo passed by our stern and ran up on the beach, where it buried itself in the sand, not exploding. This caused everyone at the stern to run to the bow.

“What transpired was a large pileup amid ship, when both running masses collided in the middle. We were lucky, our casualties were few.”

The 530th made way for a large landing force that day, placing a bridge over a river just a short distance from the landing area and maintaining it until Navy engineers could install a more permanent structure.

Canadians come up trumps at NYYC Invitational

Pondělí, Září 19th, 2011

In a reversal of fortune from the inaugural event two years ago, the Terry McLaughlin-led team from the Royal Canadian Yacht Club persevered today to win the 2011 New York Yacht Club Invitational Cup presented by Rolex, sailed in Swan 42s off Newport, Rhode Island.

The New York Yacht Club team finished second, with the Annapolis Yacht Club team, third. The final race days’ LED diving flashlight and shifty conditions gave all 22 teams the opportunity to shift positions on the leaderboard, but in the end most just solidified what they had already earned.

Olympic medallist and former America’s Cup skipper, Terry McLaughlin, went into the day – and the final race – with a 10-point lead over the NYYC entry, but the Canadians took charge from the start.

“We decided to go after New York, but it was tricky. It was five knots at the start, but it was very, very shifty and puffy. If we let them sail their own race and we had tried to sail our own race, there is a reasonable chance they could have put 10 boats between us,” McLaughlin recounted.

“We decided that we had to be near them. If we put them back at the start, and we’re back at the start, it didn’t matter and we couldn’t lose. We still both had reasonable starts at the right end and we went right a little bit. Then they (NYYC) sort of got to us a bit, so I bailed left, but we happened to be in a great puff and gained on them a lot.”

The Royal Canadian Yacht Club team from Toronto sailed a near-flawless series with seven top five finishes from 11 races.

“I think we came back quite well this series,” McLaughlin said. “Obviously yesterday was our best, going from 19th to sixth. It’s important, because you can’t get off the line in great shape or get around the first mark in great shape, eleven races in a row.”

The 55-year old won Silver in the Flying Dutchman class in the 1984 Los Angeles Olympics and was skipper of Canada I in the 1983 America’s Cup challenger series. In fact, three of his crew came from that Cup campaign.

In a new addition to the event, the team that leads on points at the end of each day gets to fly a ‘gold’ spinnaker in the following day’s races. The Royal Canadian team quickly took that honour after the first day and never relinquished it for the week.

McLaughlin was quick to praise his crew, “It was a team effort. I mean, I make the final decisions, but I’m relying on guys that A) make the boat go fast and B) tell me what’s going on.”
