Veterinary Feed Directive
A Veterinary Feed Directive (VFD) is, under the law of the United States, a written authorization allowing animal keepers to use animal feed containing specified antibiotics in accordance with Food and Drug Administration The United States Food and Drug Administration (FDA or US FDA) is a List of United States federal agencies, federal agency of the United States Department of Health and Human Services, Department of Health and Human Services. The FDA is respo ... (FDA) approved directions for use. Synopsis The requirement for a VFD was created by the Animal Drug Availability Act 1996 (P.L. 104-250). Regulations related to the VFD are published by the FDA's Center for Veterinary Medicine in 21 CFR 510, 514, and 558. A VFD is required for any species of animal fed medicated feed containing a VFD drug; this law is not limited to livestock. VFD drugs must be used under the professional supervision of a licensed veterinarian. The purpose of implementing the VFD is to aid in ...

Volunteer Fire Department
A volunteer fire department (VFD) is a fire department of volunteers who perform fire suppression and other related emergency services for a local jurisdiction. Volunteer and retained (on-call) firefighters are expected to be on call to respond to emergency calls for long periods of time, and are summoned to the fire station when their services are needed. They are also expected to attend other non-emergency duties as well (training, fundraising, equipment maintenance, etc.). Volunteer firefighters contrast with paid firefighters who work full or part-time and receive a salary. Some volunteer firefighters may be part of a combination fire department that employs both full-time and volunteer firefighters. On-call firefighters who receive some pay for their work are known as call firefighters in the United States, and retained firefighters in the United Kingdom and Ireland. International The earliest firefighting organizations were made up of volunteers. The first large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vacuum Fluorescent Display
A vacuum fluorescent display (VFD) is a display device once commonly used on consumer electronics equipment such as video cassette recorders, car audio, car radios, and microwave ovens. A VFD operates on the principle of cathodoluminescence, roughly similar to a cathode-ray tube, but operating at much lower voltages. Each tube in a VFD has a phosphor-coated carbon anode that is bombarded by electrons emitted from the thermionic cathode, cathode filament.Chen, J., Cranton, W., & Fihn, M. (Eds.). (2016). Handbook of Visual Display Technology. doi:10.1007/978-3-319-14346-0 page 1610 onwards In fact, each tube in a VFD is a triode vacuum tube because it also has a mesh control grid. Unlike liquid crystal displays (LCDs), a VFD emits very bright light with high contrast and can support display elements of various colors. Standard illumination figures for VFDs are around 640 Candela per square metre, cd/m2 with high-brightness VFDs operating at 4,000 cd/m2, and experimental un ...

Variable-frequency Drive
A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor, AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the input electricity. Depending on its Topology (electrical circuits), topology, it controls the associated voltage or electric current, current variation., quote is per definition on p. 4 of NEMA Standards Publication ICS 7.2-2021. VFDs are used in applications ranging from small appliances to large compressors. Systems using VFDs can be more efficient than hydraulics, hydraulic systems, such as in systems with pumps and damper control for fans. Since the 1980s, power electronics technology has reduced VFD cost and size and has improved performance through advances in semiconductor switching devices, drive topologies, simulation and control techniques ...

Virtual Floppy Disk (file Type)
VHD (Virtual Hard Disk) and its successor VHDX are file formats representing a virtual hard disk drive (HDD). They may contain what is found on a physical HDD, such as disk partitions and a file system, which in turn can contain computer file, files and Folder (computing), folders. They are typically used as the hard disk of a virtual machine, are built into modern versions of Windows, and are the native file format for Microsoft's hypervisor (virtual machine system), Hyper-V. The format was created by Connectix for their Virtual PC product, known as Microsoft Virtual PC since Microsoft acquired Connectix in 2003. VHDX was introduced in Windows 8/Windows Server 2012 to add features and flexibility missing in VHD that had become apparent over time. Since June 2005, Microsoft has made the VHD and VHDX Image Format Specifications available to third parties under the Microsoft Open Specification Promise. Features A Virtual Hard Disk allows multiple operating systems to resid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Factory Workers' Union Of Germany
The Factory Workers' Union of Germany (, VFD, commonly known as , FAV) was a trade union in Germany. History The union was founded in early July 1890, as a general union affiliated to the General Commission of German Trade Unions, gathering unskilled workers from many different industrial sectors. It was initially named the Union of Factory, Agricultural and Commercial Support Workers in Germany It grew rapidly, with 11,000 members by 1896, and 76,000 by 1905. However, in 1906, it decided to only represent workers in six industries: * Chemical industry * Paper making * Brick making * Sugar refining * Agriculture * Dairies, distilleries and related trades In light of this, in 1908, it changed its name to the "Factory Workers' Union of Germany", and by 1912, it had come to focus on the chemical, paper, building materials, and food industries. This strategy proved successful, and by 1913 the membership had reached 210,000. That year, the Union of Flower Workers joined, while t ...

Vicarius Filii Dei
''Vicarius Filii Dei'' (Latin: ''Vicar'' or ''Representative of the Son of God'') is a phrase first used in the forged medieval '' Donation of Constantine'' to refer to Saint Peter, who is regarded as the first Pope by the Catholic Church. Origins and uses of the phrase The earliest known instance of the phrase ''Vicarius Filii Dei'' is in the '' Donation of Constantine'', now dated between the eighth and the ninth centuries AD. Johann Peter Kirsch states that "many of the recent critical students of the document .e. Donation of Constantinelocate its composition at Rome and attribute the forgery to an ecclesiastic, their chief argument being an intrinsic one: this false document was composed in favour of the popes and of the Holy Catholic Roman Church, therefore the Christ Church itself must have had the chief interest in a forgery executed for a purpose so clearly expressed". However, it goes on to state, "Grauert, for whom the forger is a Frankish subject, shares the view ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
