QD (retailer)
QD Stores Limited (trading as Quality Discounts and QD) is a British independently-owned discount retailer operating in the United Kingdom, primarily in East Anglia and the East Midlands regions. Products stocked include a mixture of items for the home and garden, basic groceries and a range of clothing and footwear. The company also run Cherry Lane Garden Centres. History The first QD Stores branch was opened in Norwich in 1985, with the initials QD standing for ''quality discounts''. During the 1990s QD Stores purchased the small department store Lathams of Potter Heigham, which it still operates under the original name. It also established Cherry Lane Garden Centres in 2001, which by 2008 had become the eighth biggest UK gardening centre group. The number of QD Stores locations has grown relatively slowly since 1985. Notable changes to the store estate include the opening of eight new stores in former Woolworths locations following that company's closure in 2009. However ...

Dobrolet (airline)
Dobrolet LLC () was a Russian low-cost airline - a subsidiary of Aeroflot - based at Sheremetyevo International Airport. It operated scheduled flights to domestic destinations before it ceased operation on 4 August 2014. History Background The operation of low-cost airlines in Russia to date has not been met with success. Sky Express was the first attempt at a Russian low-cost airline and began operations in 2007; it ceased operations in October 2011 after experiencing financial difficulties with all aircraft and flights being transferred to Kuban Airlines. Avianova, founded in 2009 and the fastest growing low-cost airline in Russia, ceased operations twenty days before SkyExpress due to unresolvable disputes between its shareholders; the Russian A1 Investments and the US-based Indigo Partners. In October 2012, Aeroflot General-Director Vitaly Savelyev held a meeting with Russian President Vladimir Putin at Novo-Ogaryovo residence at which the operations of the Russian flag ...

Quantum Dot
Quantum dots (QDs) or semiconductor nanocrystals are semiconductor particles a few nanometres in size with optical and electronic properties that differ from those of larger particles via quantum mechanical effects. They are a central topic in nanotechnology and materials science. When a quantum dot is illuminated by UV light, an electron in the quantum dot can be excited to a state of higher energy. In the case of a semiconducting quantum dot, this process corresponds to the transition of an electron from the valence band to the conduction band. The excited electron can drop back into the valence band releasing its energy as light. This light emission ( photoluminescence) is illustrated in the figure on the right. The color of that light depends on the energy difference between the discrete energy levels of the quantum dot in the conduction band and the valence band. In other words, a quantum dot can be defined as a structure on a semiconductor which is capable of confi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
N-Gage QD
The N-Gage is a mobile device combining features of a cellular phone and a handheld game system developed by Nokia, released on 7 October 2003. Officially nicknamed the ''game deck'', the N-Gage's phone works on the GSM cellular network, and software-wise runs on the Series 60 platform on top of Symbian OS v6.1. N-Gage attempted to lure gamers away from the Game Boy Advance by including telephone functionality, including SMS texting, in an "all-in-one" device. Game software was packaged in a MultiMediaCard to be inserted into the N-Gage's slot. Nokia also ran an online service community, N-Gage Arena, which also supported multiplayer on some titles, using the phone's GPRS data connection. Ultimately over 50 games — which included titles by major third-party publishers — were released for the system in a three year period. The N-Gage was unsuccessful, partly because the buttons were not well-suited for gaming, while it was described as resembling a taco, which led to i ...

IOPS
Input/output operations per second (IOPS, pronounced ''eye-ops'') is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN). Like benchmarks, IOPS numbers published by storage device manufacturers do not directly relate to real-world application performance. Background To meaningfully describe the performance characteristics of any storage device, it is necessary to specify a minimum of three metrics simultaneously: IOPS, response time, and (application) workload. Absent simultaneous specifications of response-time and workload, IOPS are essentially meaningless. In isolation, IOPS can be considered analogous to "revolutions per minute" of an automobile engine i.e. an engine capable of spinning at 10,000 RPMs with its transmission in neutral does not convey anything of value, however an engine capable of developing specified torque and horsepower at a given number ...

Quick Disk
A floppy disk is a disk storage medium composed of a thin and flexible magnetic storage medium encased in a rectangular plastic carrier. It is read and written using a floppy disk drive (FDD). Floppy disks were an almost universal data format from the 1970s into the 1990s, used for primary data storage as well as for backup and data transfers between computers. In 1967, at an IBM facility in San Jose, California, work began on a drive that led to the world's first floppy disk and disk drive. It was introduced into the market in an format in 1971. The more conveniently sized 5¼-inch disks were introduced in 1976, and became almost universal on dedicated word processing systems and personal computers. This format was more slowly replaced by the 3½-inch format, first introduced in 1982. There was a significant period where both were popular. A number of other variant sizes were introduced over time, with limited market success. Floppy disks remained a popular medium for nearly ...
