NATO ships, helicopters hunt down 7 pirates
NAIROBI, Kenya - NATO warships and helicopters pursued Somali pirates for seven hours after they attacked a Norwegian tanker, NATO spokesmen said Sunday, and the high-speed chase only ended when warning shots were fired at the pirates' skiff. Seven pirates attempted to attack the Norwegian-flagged MV Front Ardenne late Saturday but fled after crew took evasive maneuvers and alerted warships in the area, said Portuguese Lt. Cmdr. Alexandre Santos Fernandes, aboard a warship in the Gulf of Aden, and Cmdr. Chris Davies, of NATais maritime headquarters in England.
"How the attack was thwarted is unclear, it appears to have been the actions of the tanker," Davies said. Fernandes said no shots were fired at the tanker.
Davies said the pirates sailed into the path of the Canadian warship Winnipeg, which was escorting a World Food Program delivery ship through the Gulf of Aden. The American ship USS Halyburton was also in the area and joined the chase.
"There was a lengthy pursuit, over seven hours," Davies said. The pirates hurled weapons into the dark seas as the Canadian and U.S. warships closed in. The ships are part of NATais anti-piracy mission.
"The skiff abandoned the scene and tried to escape to Somali territory," Fernandes said. "It was heading toward Bossaso but we managed to track them. Warning shots have been made after several attempts to stop the vessel."
Both ships deployed helicopters, and naval officers hailed the pirates over loudspeakers and finally fired warning shots to stop them, Fernandes said, but not before the pirates had dumped most of their weapons overboard. NATO forces boarded the skiff, where they found a rocketpropelled grenade, and interrogated, disarmed and released the pirates.
The pirates cannot be prosecuted under Canadian law because they did not attack Canadian citizens or interests and the crime was not committed on Canadian territory.
"When a ship is part of NATO, the detention of a person is a matter for the national authorities," Fernandes said. "It stops being a NATO issue and starts being a national issue."
The pirates' release underscores the difficulties navies have in fighting rampant piracy off the coast of lawless Somalia. Most of the time, foreign navies simply disarm and release the pirates they catch due to legal complications and logistical difficulties in transporting pirates and witnesses to court.
Pirates have attacked more than 80 boats this year alone, four times the number assaulted in 2003, according to the Kuala Lumpur-based International Maritime Bureau. They now hold at least 18 ships - including a Belgian tanker seized Saturday with 10 crew aboard - and over 310 crew hostage, according to an Associated Press count.

REAL BLUE SKY RESEARCH
Just where in the world is the bluest sky? Expedia wanted to know for its "Blue Sky Explorer" project. They asked NPL to develop a blue sky standard and some cheap equipment to measure it. Their solution was to use cheap light-emitting diodes as the light standard, rather than the typical expensive noble gas lamps, and the belt-and-braces device was calibrated against an international "colourimetry" standard.
The result? Rio de Janeiro came out on top, followed by the Bay of Islands in New Zealand and Uluru in Australia. Unsurprisingly the UK did not figure in strongly in the top 10, but Castell Dinas Bran in Wales came in at number nine.

Which is the best alternative considering some of the statements are true (T) and others are false (F) ?
I- The research is about the colour of the sky in different parts of the planet.
II- Expedia used a previous blue sky standard in the research.
III- The lamps that are currently used in the measurement were replaced by cheap ones.
IV- NPL adjusted the device to use an international "colourimentry" standard.
V- Rio de Janeiro and New Zealand got first rank in the Research while Australia came in second.
VI- It was a surprise that the UK did not figure in strongly in the top 10.

GATES HAILS SOLDIER SNAPPED IN PINK BOXER SHORTS
Defense Secretary Robert Gates on Thursday praised an Army soldier in eastern Afghanistan who drew media attention this month after rushing to defend his post from attack while wearing pink boxer shorts and flip-flops, Reuters reported. Gates said in prepared remarks that he wants to meet the soldier and shake his hand the next time he visits Afghanistan.
"Any soldier who goes into battle against the Taliban in pink boxers and flip-flops has a special kind of courage, " Gates said in a speech to be delivered in New York. "I can only wonder about the impact on the Taliban. Just imagine seeing that: a guy in pink boxers and flip-flops has you in his cross-hairs. What an incredible innovation in psychological warfare, " he said.
Army Specialist Zachary Boyd, 19, of Fort Worth, Texas, rushed from his sleeping quarters on May 11 to join fellow platoon members at a base in Afghanistan's Kunar Province after the unit came under fire from Taliban positions. A news photographer was on hand to record the image of Boyd standing at a makeshift rampart in helmet, body armor, red T-shirt and boxers emblazoned with the message: "I love NY". When the image wound up on the front page of the New York Times, Boyd told his parents he might lose his job if President Obama saw him out of uniform.

Climate change over the next 20 years could result in a
global catastrophe costing millions of lives in wars and natural
disasters.
A secret report, suppressed by US defense chiefs and
obtained by The Observer, warns that major European cities will
be sunk beneath rising seas as Britain is plunged into a
'Siberian' climate by 2020. Nuclear conflict, mega-droughts,
famine and widespread rioting will erupt across the world.
The document predicts that abrupt climate change could bring
the planet to the edge of anarchy as countries develop a nuclear
threat to defend and secure dwindling food, water and energy
supplies. The threat to global stability vastly eclipses that of
terrorism, say the few experts privy to its contents.
'Disruption and conflict will be endemic features of life,'
concludes the Pentagon analysis. 'Once again, warfare would
define human life.'

Cairo -- Egypt has begun forcibly slaughtering the country's
pig herds as a precaution against swine flu, a move that the
United Nations described as "a real mistake" and one that is
prompting anger among the country's pig farmers.
The decision, announced Wednesday, is already adding new
strains to the tense relations between Egypt's majority Muslims
and its Coptic Christians. Most of Egypt's pig farmers are
Christians, and some accuse the government of using swine flu
fears to punish them economically.

Credit card companies in the US will soon be bound by new restrictions on their ability to charge fees, or raise interest rates on existing borrowings.
The bill is designed to protect credit card users from unexpected fees or increases to their interest rates.
The US government has been concerned to tighten its regulation of the banking system in the light of the credit crunch and banking crisis.
"This cements a victory for every American consumer who has ever suffered at the hands of the credit card industry, " said Senator Christopher Dodd, chairman of the Senate banking committee.
Americans currently owe nearly $1 trillion on their credit cards. The US government has been concerned to tighten its regulation of the banking system in the light of the credit crunch and banking crisis.

The rescue of Captain Phillips drew widespread praise for the Navy and Mr. Obama, but some experts warned that it could escalate the campaign by Somali pirates, who have vowed to take revenge on Americans and are holding more than 200 hostages from other countries.
Mr. Obama praised Captain Phillips for his "courage and leadership and selfless concern for his crew, " and he said he was "very proud" of the Navy and other American agencies involved in the operation.

One of the most important sources of force on a ship is her own propeller and the pilot must understand the action of a propeller in order to be able to predict its action on ship.
A propeller produces side forces in addition to thrust along the propeller shaft. A ship can rotates to starboard or port as function of these side forces.
Pilot Antonio is studying propeller side force, on a single right-hand screw propeller, and knows that it can be broken down in four parts: following wake effect, inclination effect, helical discharge effect and shallow submergence effect. Antonio wrote the following consideration:
I) The following wake effect produces a net force tending to move the stern to right and cause the ship to veer to the port.
II) The inclination effect is net effect that tends to twist the ship to the right.
III) The shallow submergence effect tends the stern to starboard and cause the ship to veer to the left.
IV) The helical discharge effect tends to turn the ship to the right.
From the list of Antonio is correct to affirm, according to the book “Naval Shiphandling”, that:
