Transport and telecommunications struggle amid confusion in London

Thursday, July 7, 2005

Amid the confusion surrounding today’s London blasts, officials have urged the public to avoid the city if possible to allow emergency services to operate more quickly.

All rail and underground stations remain closed, although efforts are being made to reopen them. Air links are now closed at Stansted, Heathrow, Gatwick and London City airports.

Those trying to contact friends and family via mobile have struggled as the largest mobile networks, Vodafone, O2 and Orange, have all suffered from full capacity on several occasions this morning meaning voice calls failed.

On the web, websites such as BBC, TfL and the G8 2005 website struggled for a short time at one point this morning under the strain of so many web users visiting them. The national grid has said that it has sustained no damage to the electricity network.On the Traffic England site run by the Highways Agency, London has been marked as a ‘Closed area’.

The Royal Mail is warning customers that mail collections and deliveries across the UK will be disrupted because of the incidents. Royal Mail vehicles will not be moving in or out of London, or between Royal Mail sites in central London for the remainder of today. At least 25 per cent of the UK’s mail moves through London, even if its end destination is elsewhere. Disruption may therefore be felt throughout the UK. Royal Mail expects to issue further information later today.

Bus services in Zone 1 have resumed as of 16:00 BST.

US, UK investigators seek 777 engine redesign to stop repeat of London jet crash

Saturday, March 14, 2009

Investigators with the National Transportation Safety Board in the United States have issued an ‘urgent safety recommendation’ in connection to their role alongside the United Kingdom’s Air Accidents Investigation Branch in investigating loss of power in Rolls-Royce engines on Boeing 777s, with the AAIB following suit. One of them resulted in British Airways Flight 38 crashing short of the runway at London’s Heathrow Airport last year. The NTSB and the AAIB want Rolls-Royce to redesign the engines.

Both events occurred on Boeing 777-200ER airplanes powered by Rolls-Royce RB211 Trent 800 Series engines. On January 17, 2008 British Airways Flight 38 experienced a dual engine rollback (reduction of engine power) on final approach to Heathrow and crashed, leaving one passenger seriously injured, eight passengers and four of the flight crew with minor injuries and the airplane written off.

The second event occurred on November 26, 2008, when a Delta Air Lines Boeing 777 experienced a single engine rollback during cruise flight over Montana, United States while en route from Shanghai to Atlanta. Normal operations resumed after the flight crew followed Boeing’s published procedure to recover engine performance and the airplane landed safely in Atlanta.

Boeing has already developed new procedures after the crash to prevent ice from building up within their 777 fuel systems after it became apparent that icing may have been a factor, and it was some of these that the Delta flight crew had followed. Boeing modified these further after the Delta incident. As part of the recent releases by the NTSB and AAIB it has become apparent that investigators from both bodies, which are collaborating, have found ice buildup in the fuel system caused both rollbacks.

In both cases a build-up of ice (from water normally present in all jet fuel) developed on a component called the fuel/oil heat exchanger. This restricted the flow of fuel to the engine, resulting in the uncommanded engine rollback. Investigators initially struggled to produce enough ice under test conditions but have now found that at high concentration, fuel can form ice at very low temperatures in enough quantity to seriously restrict fuel flow, according to a new interim report by the AAIB. This does not occur when fuel demand is lower, as the hot oil then becomes sufficient to entirely melt the ice. The British jet experienced very low temperatures over Siberia.

The vigorous tests are thought to be the first of their kind. They have also confirmed that while ice may have formed elsewhere in the airliner’s fuel system fuel was probably not restricted at any other location. Instead, it is thought ‘soft’ ice formed in the pipes and then broke off, travelling to the fuel/oil heat exchanger and restricting it.

The NTSB has now revealed that they have advised Rolls-Royce to redesign the fuel/oil heat exchanger, and Rolls-Royce have stated that they are indeed working on a replacement part that will be available within twelve months. The AAIB advised Boeing and Rolls-Royce to jointly review the problem across the fuel system, and both companies responded that they ‘accepted’ this recommendation and repeated that a replacement part was being developed.

Both the NTSB and the AAIB also sent letters to the US Federal Aviation Administration and the European Aviation Safety Agency requesting the installment of the modified component be mandatory. The NTSB suggested this should be either the next maintenance check or within six months. There are 220 Boeing 777-200s – the only type using the affected engine – with Trent 800 series engines.

The fuel/oil heat exchanger is a dual purpose part designed to simultaneously melt fuel ice and cool down engine oil.

The AAIB further noted that it is unclear weather other aircraft designs are at risk, and advised the FAA and EASA to look into increased use of de-icing additives and investigate both the accumulation and sudden movement of ice in aircraft fuel systems and the actual formation of ice in the fuel itself.

Stores in Australia lower toilet paper limits per transaction

Friday, March 13, 2020

On Sunday and Saturday evening, Australian store chains Woolworths and Coles lowered their purchase restrictions on toilet paper to two and one package per transaction in all stores on national level, respectively. ALDI also introduced a one-pack limit, on Monday. These limitations were posted as messages on the checkouts, and on the chains’ Facebook pages. Buyers were reportedly stocking up due to fears of COVID-19 in case people need to self-isolate. On Wednesday, Woolworths also limited toilet paper purchases for home delivery to one pack per order.

These changes followed the previous four-pack per transaction restriction introduced by Woolworths and Coles on March 4 and 5 respectively. Coles, in its March 8 media release, reported that with the four-pack restriction in place, “many stores are still selling out within an hour of delivery”, and called the demand “unprecedented”, while ALDI, in a Facebook post on Tuesday, called it “unexpected”. Sales went up in a “sharp increase” last week, according to a Woolworths spokesperson. Costco’s store in Canberra also limited the allowed amount to two packs last week.

To further alleviate the shortage, Coles ordered bigger packages from suppliers and increased delivery frequency, Woolworths ordered extra stock, while ALDI made stocks for a planned Wednesday special available early. Russell Zimmerman, executive director of the Australian Retailers Association, said that retailers try to raise stock, but local council restrictions on the timing of truck-deliveries make it hard. He expects rising production costs, as suppliers try to meet demand, and fewer specials. On Tuesday, ALDI announced that following the early release of stock, some stores can’t run the Wednesday special.

In a News.com.au report, Dr Gary Mortimer, retail expert from Queensland University of Technology, said the stores fill the stock every night. He remarked toilet paper is a bulky item, leading to low quantity of stocks in numbers, and, when sold out, leaves vast shelf spaces empty, hardening the feeling of a shortage. “Coles and Woolworths have a view [that] if there was plenty of stuff on the shelf, if product like toilet rolls and sanitiser could be [bought] and are there in quantities, you would probably minimise the panic” said Russell Zimmerman per ABC News.

Recycled toilet paper producer Who Gives a Crap said on last Wednesday they’d run out of stock. Kimberly-Clark, which makes Kleenex Toilet Tissue, and Solaris Paper which makes Sorbent, emphasized they were working 24/7 to maintain the supply, according to the News.com.au report.

Domain.com, a real estate site, reported some property sellers offering free toilet paper to the first bidder on auctions in Melbourne, when fewer auctions were held because of buyers having time off on the long weekend of Labour Day. The Thursday edition of NT News, a daily printed in Darwin, included an eight-page insert meant to be cut up and used as toilet paper.

The stores were originally reluctant to impose restrictions, according to a report from ABC Australia on March 3 in which they said they had no plans to introduce restrictions on the purchases.

Russell Zimmerman added that other products are also in high demand, including masks, sanitiser, dried goods, handwash and flour. Similarly, outside of Australia, on Sunday evening online British supermarket Ocado was observed limiting purchases of Andres toilet paper to two 12-roll packs.

Wikinews interviews U.S. Libertarian presidential candidate Wayne Allyn Root

Wednesday, February 6, 2008

Wikinews held an exclusive interview with Wayne Allyn Root, one of the candidates for the Libertarian Party nomination for the 2008 U.S. presidential election.

Root is the founder and chairman of Winning Edge International Inc., a sports handicapping company based in Las Vegas, Nevada. In addition, he is an author and a television producer, as well as an on-screen personality both as host and guest on several talk shows.

Root, a long-time Republican, declared his candidacy for the Libertarian Party on May 4, 2007.

He says he is concerned about the qualities of many who run for president, and fears that they do not know the needs of American citizens. He also says that they cater to big businesses instead of small ones.

He has goals of limiting the federal government and believes that the US went into Iraq for wrong reasons. A strong supporter of the War on Terror, he feels that it was mishandled. He has conservative values and came from a blue collar family in New York. He graduated from Columbia University with fellow presidential hopeful Barack Obama in 1983.

Root believes that America is in trouble and hopes to change that if elected.

A Guide For Picking A Jewelry Display Folder

A Guide for Picking a Jewelry Display Folder

Choosing the right jewelry folder which meet your particular needs may appear to be a daunting job when considering all of the different options you can buy. Jewelry display folders certainly are a very good option for under the counter storage when it comes to a fine jeweler\’s excess jewelry; folders are also very good for traveling jewelry salesmen looking to sell their good. Jewelry manufacturers trying to deliver their merchandise to retailers can generate a quite striking impression by delivering their jewelry in a good quality jewelry presentation folder directly to the to the retail store. Take note, the jewelry folder display designed for traveling jewelers are going to work great in a retail store.

It is important that your presentation folder for jewelry really needs to have the color scheme to show off your brand. Be aware, your jewelry presentation folder should be seen as a good starting point for building up your brand color(s), if your company does not yet possess a particular brand color. A good jewelry folder often have several colors, but the background surface that your fine jewelry rests against must be neutral, as the jewelry must still be the star. Customized colors and logos for the jewelry display folders are a must if that you hope to build your company\’s brand and showcase your unique style to potential jewelry buyers. Jewelers must match their jewelry presentation folders with the rest of their displays.

Sadly, a good number of those jewelry display folders one can buy are produced overseas which means second-rate product quality. I\’ve personally witnessed jewelry display folders start fall apart with a few dozen uses, which may produce a poor presentation or potentially even severely damaged jewelry. Make sure your jewelry folder display are made in the USA or at the very least Germany, because the jewelry display folder tend to last far better compared to the jewelry display folder manufactured overseas; these jewelry presentation folder sadly do not last long in cases when they are used significantly. When selecting the best presentation folder for jewelry display, do not simply buy a random product online and hope that the jewelry folder works, you must get sample jewelry folder so you can make sure the product works with your unique jewelry well.

Jewelry presentation folders that are produced out of high quality canvas fabric withstand damage better when compared with lesser quality materials; folders made from cheap leather tend to break with little use. Any good jewelry presentation folder must be closed securely with Velcro or something similar to close the jewelry folder, this is especially critical assuming you would like to keep your fine jewelry safe. Your presentation folder for jewelry display must not be made with a leather exterior as the folder has a high chance of being damaged, but, using leather inside the jewelry folder is really very nice. Jewelry folders often tear open without much use if the closing mechanism is insufficient. Travelite Jewelry Display Folders are the only jewelry folders which successfully uses both ballistic fabric and a strong Velcro mechanism at the same time.

As a general rule, do not show a very large number of pieces of jewelry in a single jewelry folder because it will devalue your jewelry by making it difficult to be seen clearly due to congestion. Don\’t be counting pennies when buying a jewelry display folder, as you will undoubtedly bear the cost in the long term. It is important to note the quality of your particular jewelry presentation folder is a reflection of your jewelry\’s quality, therefore a cheap folder displays a subpar jewelry quality. Please be aware that a really good jewelry display folder could increase the perceived value of your jewelry substantially, the price you pay for a really good folder could be worth its weight in gold with only a slight increase in the sales of your jewelry, this is really only a possibility if you\’re using a high quality jewelry presentation folder, that shows little or no signs of wear and tear.
