VSD (French Magazine)
''VSD'' is a French weekly news, celebrity and leisure magazine, published on Thursdays in France. The name is formed from the first letters of the French names for Friday (Vendredi), Saturday (Samedi) and Sunday (Dimanche). History ''VSD'' was first published on 9 September 1977 by Maurice Siegel. After Siegel's death in 1985, direction passed to his sons François and Jean-Dominique. Publication ceased in August 1995. The title was purchased by Prisma Presse, formerly a media subsidiary of the German company Bertelsmann and relaunched in June 1996. Like its rival ''Paris Match'' it relies heavily on paparazzi photography and celebrity news. ''VSD'' is published on a weekly basis. Circulation The circulation of ''VSD'' in the 1980s reached 400,000 copies. The 1998 circulation of the weekly was 235,000 copies. In 2001 ''VSD'' had a circulation of 216,000 copies. The magazine had a circulation of 204,036 copies in 2005 and 197,482 copies in 2006. Its circulation grew to 217,7 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaccine Safety Datalink
The Vaccine Safety Datalink Project (VSD) was established in 1990 by the United States Centers for Disease Control and Prevention (CDC) to study the adverse effects of vaccines. Four large health maintenance organizations, including Kaiser Permanente, were initially recruited to provide the CDC with medical data on vaccination histories, health outcomes, and subject characteristics. The VSD database contains data compiled from surveillance on more than seven million people in the United States, including about 500,000 children from birth through age six years (2% of the U.S. population in this age group). The VSD data-sharing program is now being administered by the National Center for Health Statistics Research Data Center. The data sharing guidelines have been revised to include comments from interested groups as well as recommendations from the Institute of Medicine (IOM). The Vaccine Adverse Event Reporting System (VAERS), the VSD, and the Clinical Immunization Safety As ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adjustable-speed Drive
A motor drive is a physical system that includes a motor. An adjustable speed motor drive is a system that includes a motor that has multiple operating speeds. A variable speed motor drive is a system that includes a motor that is continuously variable in speed. If the motor is generating electrical energy rather than using it, the motor drive could be called a generator drive but is often still referred to as a motor drive. A variable frequency drive (VFD) or variable speed drive (VSD) describes the electronic portion of the system that controls the speed of the motor. More generally, the term ''drive'', describes equipment used to control the speed of machinery. Many industrial processes such as assembly lines must operate at different speeds for different products. Where process conditions demand adjustment of flow from a pump or fan, varying the speed of the drive may save energy compared with other techniques for flow control. Where speeds may be selected from several diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hidden-surface Determination
In 3D computer graphics, hidden-surface determination (also known as shown-surface determination, hidden-surface removal (HSR), occlusion culling (OC) or visible-surface determination (VSD)) is the process of identifying what Computer representation of surfaces, surfaces and parts of surfaces can be seen from a particular viewing angle. A hidden-surface determination algorithm is a solution to the visibility problem, which was one of the first major problems in the field of 3D computer graphics. The process of hidden-surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider. When referring to line rendering it is known as hidden-line removal. Hidden-surface determination is necessary to render a scene correctly, so that one may not view features hidden behind the model itself, allowing only the naturally viewable portion of the graphic to be visible. Background Hidden-surface determination is a process that identifies which surfaces are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Single Disc
Video Single Disc (VSD) is a disc-based format that carried the same analog video information as a LaserDisc, but on a 12-centimetre (4.75 inch) diameter CD-sized disc. It was spearheaded by Sony and was released in Japan in 1990. It was a new variety of laserdisc and variation on the CD Video (CD-V) format, except that VSD disc carried only a video track (of up to 5 minutes' duration), and its associated audio, with no CD-compatible partition. The disc is the same size as a standard CD and holds five minutes of video with digital sound. It did not have any additional audio tracks like CD-V. Like CD-V, VSD discs could be played back by multi-disc or LaserDisc players that had VSD playback capability. Release Upon release, the Video Single Disc was seen as a possible replacement for the failing “CD Video” format, which had confused the public with its combination of five minutes of video and 20 minutes of audio. Cost In Japan the Video Single Disc (VSD) was listed at around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voluntary Service Detachment
The Voluntary Service Detachments were offshoots of the Australian Red Cross Society's South Australian and Western Australian divisions formed shortly before the outbreak of World War II. Their aim was to train and co-ordinate women volunteers as first aiders and civil defence personnel. History Following a suggestion by Harold Thorby MHR, a committee was formed in December 1938 headed by Geoffrey Reed KC to formulate plans for a service. Within a week three detachments had been formed: at the GPO, Adelaide, the South Australian Gas Company, and in Unley, South Australia. Dr. Russell was appointed director, Mrs. P. E. Stow was appointed secretary; Emily Dutton was coordinator for the country areas. There was a substantial early response from potential volunteers and businesses willing to host detachments. The organisation had its headquarters at Stow Building, Flinders Street. Within a month dozens of detachments had been formed and some six hundred women had joined. Follow ...

State Security Department Of Lithuania
The State Security Department or VSD () is a Lithuanian intelligence agency which collects information on threats to national security and works to eliminate those threats. The VSD also conducts counterintelligence, protects state secrets and classified information, and vets certain applicants for residence permits or entry to Lithuania. History The origins of the institution are in the ''Intelligence Unit'' established within the Lithuanian Armed Forces on 27 October 1918. The first head of the intelligence service was Jonas Žilinskas. In 1923, many intelligence activities were transferred to the Ministry of the Interior and the institution changed its name over time. In 1933 it was re-organized into the ''State Security Department'' with the objective to suppress espionage activities. The last director of the service in the interwar period was Augustinas Povilaitis. In the aftermath of the Soviet invasion and occupation in 1940, he was arrested and executed by the Soviets. ...

Ventilation Shutdown
Ventilation shutdown (VSD) is a means to kill livestock by suffocation and heat stroke in which airways to the building in which the livestock are kept are cut off. It is used for mass killing — usually to prevent the spread of diseases such as avian influenza. Animal rights organizations have called the practice unethical. The addition of carbon dioxide or additional heat to the enclosure is known as ventilation shutdown plus (VSD+). History The term ventilation shutdown appears to have originated in 2006 from the United Kingdom Department for Environment, Food and Rural Affairs. The practice was first permitted in the UK on April 29th, 2006. In the United States, approval to use ventilation shutdown was given in 2015. In 2020, supply chain disruptions from the COVID-19 pandemic led to many meat plant closures and in turn backup in slaughtering. In response, millions of US farm animals were killed via mass depopulation methods with ventilation shutdown often being chosen. The ...

Ventricular Septal Defect
A ventricular septal defect (VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. It's a common heart problem present at birth ( congenital heart defect). The extent of the opening may vary from pin size to complete absence of the ventricular septum, creating one common ventricle. The ventricular septum consists of an inferior muscular and superior membranous portion and is extensively innervated with conducting cardiomyocytes. The membranous portion, which is close to the atrioventricular node, is most commonly affected in adults and older children in the United States. It is also the type that will most commonly require surgical intervention, comprising over 80% of cases. Membranous ventricular septal defects are more common than muscular ventricular septal defects, and are the most common congenital cardiac anomaly. Signs and symptoms Ventricular septal defect is usually symptomless at birth. It usually manifests a fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtually Safe Dose
A virtually safe dose (VSD) may be determined for those carcinogens not assumed to have a threshold. Virtually safe doses are calculated by regulatory agencies to represent the level of exposure to such carcinogenic agents at which an excess of cancers greater than that level accepted by society is not expected.Derelanko, M.J. and Hollinger, M.A. (Eds).
