|SYDNEY Cheap Doug Wickenheiser Jersey , Sept. 14 (Xinhua) -- Power was restored in Papua New Guinea on Wednesday evening, after an electronic payment glitch left tens of thousands of people without electricity for three days.
PNG Power Limited said in a statement obtained by Xinhua, that Monday's major system failure was due to ""our Easipay Database collapsing due to technical faults.""
The pre-paid power system is typically purchased by customers through mobile phone apps or at stores that sell vouchers.
However, on Monday, those without power credit were unable to top-up their accounts.
Left fuming, one PNG resident told local media she ""can't cope up with the fact that PNG Power doesn't have a backup system in play.""
""It's just unrealistic!"" she said.
But with power finally restored Cheap Brian Sutter Jersey , PNG Power thanked its customers for their patience and apologised for the inconvenience.
""PNG Power Limited's information and technology officers, along with our New Zealand Vendor all worked tirelessly around the clock to restore the system,"" the company said.

" If you have been looking into the numerous types of lasers and laser components, YAG is one of the names that you must have seen quite often. These lasers are indeed very popular Cheap Doug Gilmour Jersey , with a wide range of practical applications. So here is what you should know about them, just to broaden your horizons and overall knowledge.
As you may already know, a laser is nothing but a device capable to emit light through optical amplification. In a few words, it is all about stimulating the emission of an electromagnetic form of radiation. After all, the term is an acronym from Light Amplification by Stimulated Emission of Radiation. A short classification of these devices would include solid state, gas Cheap Shayne Corson Jersey , excimer, dye and semiconductor lasers.
From all these types, our topic for today would enter the solid-state lasers category. The lasing material is normally distributed through a solid matrix, in our case an yttrium aluminum garnet, hence the YAG short form. It does not take much research in order to notice how the term often receives an Nd: in front of its name, which comes from neodymium-doped. What is this Nd:YAG if not a crystal? Of course Cheap Barclay Plager Jersey , the crystal is one of the many laser components, but even so, it definitely makes the central piece, as it determines the features and particularities of the final product.
Regularly used in its monocrystalline or ceramic forms, the substance presents the following properties: it makes a 4-level gain medium; it can be easily lamp or diode pumped; and it facilitates the effects of detrimental quenching because of the high excitation density of a moderate gain. Its standard wavelength emission is of 1064 nm, yet it can generate anything from 266 Cheap Keith Tkachuk Jersey , 355 or 532 nm by quadrupling, tripling or doubling the frequency. Specialists in the field really know how to joggle with the numerous components and wavelengths of these yttrium aluminum garnet lasers for optimum benefits.
Nevertheless, what kind of benefits and practical utilities are we talking about? It turns out that anyone working in medicine, manufacturing, fluid dynamics, dentistry Cheap Garry Unger Jersey , military defense, cavity ring down spectroscopy, laser induced breakdown spectroscopy, laser pumping and even automotive may eventually need it. In medicine for example, they use it for anything from removing the toenail infection to cataract surgery and skin cancer treatments! In manufacturing, they engrave all sorts of materials with this laser Cheap Red Berenson Jersey , and in fluid dynamics they implement the laser components for flow visualization techniques.
Dentists use YAG lasers for surgeries on soft tissues. At the opposite corner of utility’s spectrum, military and defense systems implement the technology in laser rangefinders and designators. As for the last and most surprising applicability, the one of automotive field, it regards a currently under research technique! Studied by some Japanese scientists, the project aims to set up an engine ignite fuel system based on YAG chips.
Needless to say, the tremendous benefits of this yttrium aluminum garnet technology are more than obvious. With tens if not hundreds of practical utilities Cheap Joe Mullen Jersey , lasers make our world a better place. Knowing how and where they work will definitely help us at one point or another.
Sydney is a city of such vast and varied treasures that it's hard to choose what to see and do especially if you're on a whirlwind visit. Fortunately Sydney's a compact place and getting around is easy so you can pack a lot into a quick visit. Here's a look at how to get the most out of Sydney when you're short on time.
First, for orientation and delightful eye candy, is a harbour trip. Much of the city's magnificence derives from its harbour location and a boat over the deep blue waters studded with white sails is a treat for the senses.
Start at Circular Quay in the business district, Sydney's transport hub and a major city terminal for buses, trains and ferries. You can get to anywhere in Sydney from here. You have the option of a wide range of excellent organised tours or you can just take the regular ferry
Other than showing you Sydney's prime location as a harbour city, this trip will offer stunning view of the whole city.
Get off the ferry to gaze at the Opera House and then take a stroll through the.
