" |
" Netsky is a prolific family of computer worms which affect Microsoft Windows operating systems. The first variant appeared on Monday, February 16, 2004. The ""B"" variant was the first family member to find its way into mass distribution. It appeared on Wednesday, February 18, 2004. 18-year-old Sven Jaschan of Germany confessed to having written these, and other worms, such as Sasser. |
" |
" Although individual functions vary widely from virus to virus, the Netsky family perhaps is most famous for comments contained within the code of its variants insulting the authors of the Bagle and Mydoom worm families and, in some cases, routines that removed versions of these viruses. The ""war"" as it was referred to in the media caused a steady increase in the number of variant viruses produced in these families. As of June 2004, Bagle had approximately 28, Netsky approximately 29, and MyDoom approximately 10. |
" |
" Other symptoms of Netsky included beeping sounds on specified dates, usually in the morning hours. |
" |
" The worm was sent out as an e-mail, enticing recipients to open an attachment. Once opened, the attached program would scan the computer for e-mail addresses and e-mail itself to all addresses found. |
" |
" Until October 2006, the P variant of this virus remained the most prevalent virus being sent in e-mail throughout the world, despite being over two and a half years old. It was surpassed by a variant from the Stration malware family in November 2006. |

"= = = Diet Rite = = = |
" |
" |
" |
" Diet Rite is a brand of no-calorie soft drinks originally distributed by the RC Cola company. |
" |
" It was introduced in 1958 and initially released as a dietetic product, but was introduced nationwide and marketed to the general public as a healthful beverage in 1962. The original formula was sweetened with cyclamate and saccharin. After cyclamate was banned in 1969, it was removed from the product. NutraSweet brand aspartame was added upon its introduction to the market, and in 1987 the saccharin was replaced entirely with together with complete elimination of caffeine. In the 1990s, several fruit-flavored varieties of Diet Rite were introduced. |
" |
" In 2000, the line was reformulated yet again, this time to replace aspartame with Splenda brand sucralose and Sunett brand Acesulfame potassium. It became the first major diet soda in the United States to use neither aspartame nor saccharin as a sweetener. In 2005, ""Pure Zero"" was added to the name, and a cherry cola flavor was introduced in 2006. |
" |
" Today it is owned by and distributed by Keurig Dr Pepper. |

"= = = J. Richard Fisher = = = |
" |
" |
" |
" James Richard Fisher (born December 10, 1943) is a scientist at the National Radio Astronomy Observatory at Charlottesville, VA. He received his Ph.D. in Astronomy in 1972 from the University of Maryland, College Park and his B.S. in Physics in 1965 from the Pennsylvania State University, University Park. |
" |
" Rick was born in Pittsburgh, PA and, at the age of 4, moved with his family to a small farm near Reynoldsville, PA where he attended Sandy Valley Elementary School, West Side Elementary School, and Reynoldsville High School where he graduated in 1961. As a boy he was interested in amateur radio and astronomy which he combined into a career in radio astronomy. |
" |
" His PhD thesis was supervised by William C. Erickson and concerned the design and prototyping for an array at the Clark Lake Radio Observatory. Much of Fisher's career has involved radio astronomy instrumentation, including telescope feed design, radio frequency interference mitigation, and signal processing. He joined NRAO in 1972 at the Green Bank, West Virginia site. He was part of the team that conceived and designed the 100-meter Green Bank Telescope there. He moved to the Central Development Lab at the Charlottesville NRAO headquarters in 2005, where he retired in 2012 but continues to be active in instrumentation projects. |
" |
" In 1978 through 1980 he spent 18 months at the Radiophysics Laboratory of CSIRO in Sydney, Australia, and on the return trip spent 2 months at the Raman Research Institute in Bangalore, India. |
" |
" Along with R. Brent Tully, he proposed the Tully-Fisher relation, a correlation between the luminosity of a galaxy and the width of emission lines in its spectrum. |

"= = = Azygos vein = = = |
" |
" |
" |
" The azygos vein is a vein running up the right side of the thoracic vertebral column draining itself towards the superior vena cava. It connects the systems of superior vena cava and inferior vena cava and can provide an alternative path for blood to the right atrium when either of the venae cavae is blocked. |
" |
" The azygos vein transports deoxygenated blood from the posterior walls of the thorax and abdomen into the superior vena cava vein. The anatomy of this blood vessel can be quite variable. In some rare variations, for example, it also drains thoracic veins, bronchial veins, and even gonadal veins. The vein is so named because it has no symmetrically equivalent vein on the left side of the body. |
" |
" The azygos system is considered to be the azygos vein located from rib number 2 to rib number 4, while on the left part of the body, the hemiazygos vein and the accessory hemiazygos vein together form the analogous venous system. |
" |
" It is formed by the union of the ascending lumbar veins with the right subcostal veins at the level of the 12th thoracic vertebra, ascending in the posterior mediastinum, and arching over the right main bronchus posteriorly at the root of the right lung to join the superior vena cava. This ""arch of the azygos vein"" (""arcus venae azygos"") is an important anatomic landmark. As an anatomical variation in 1-2% of the population, the arch can be displaced laterally, thereby creating a pleural septum separating an azygos lobe from the upper lobe of the right lung. |
" |
" A major tributary is the hemiazygos vein, a similar structure on the opposite side of the vertebral column. Other tributaries include the bronchial veins, pericardial veins, and posterior right intercostal veins. It communicates with the vertebral venous plexuses. |
" |
" The origin and anatomical course of the azygos vein are quite variable. Usually, there is a singular azygos vein on the right side of the body. However, the azygos vein is occasionally located in the midline or two independent veins may be present like in early embryonic development. |
" |
" The azygos vein generally begins at the level of the lumbar vertebrae but may originate above the point in some cases. The lumbar aspect of the azygos vein can ascend anteriorly to the lumbar vertebrae and pass behind the right crus of the diaphragm or cross the aortic hiatus (where the aorta pierces the diaphragm) to the right of the cisterna chyli, a dilated lymph sac. The common trunk of the right ascending lumbar vein and the right subcostal vein join the azygos vein anterior to the body of T12. However, if the lumbar segment is absent, this trunk may form the azygos vein. |
" |
" It has been proposed that the azygos vein develops by originally draining to the posterior cardinal vein and then to the longitudinal venous channel. Following retrogression of the left common cardinal vein, the left azygos vein loses contact with the posterior cardinal vein. Thus, the blood drains into the right azygos line. |
" |
" The azygos system of veins is considered to be the azygos vein, along with its left-sided counterparts, the hemiazygos vein and the accessory hemiazygos vein. It also creates a cavo-caval anastomosis by offering an alternative, collateral blood flow from the lower half of the body to the superior vena cava, bypassing the inferior vena cava. This can have clinical significance in any blood flow restriction of the inferior vena cava. |
" |
" Azygos vein abnormalities can be suggested on chest radiograph by enlargement of the azygos shadow to greater than 1 cm. False positives can occur in heart failure causing increased pressures on the right side of the heart, or adjacent lymphadenopathy. Azygos and hemiazygos continuation of the inferior vena cava (IVC) was not common in daily life. It is very hard to observe, particularly when it is not associated with congenital heart disease or deep venous thrombosis. Thus, it is crucial to diagnose the enlarged azygos vein at the confluence with the superior vena cava and in the retrocrural space to prevent misdiagnosis as a right-sided paratracheal mass. The loss of the intrahepatic segment of IVC with azygous and hemiazygos continuation happens in 0.6% of patients diagnosed for congenital heart disease and usually occurs simultaneously with situs inversus, asplenia, or polysplenia, persistent left superior vena cava (SVC), and congenital pulmonary venolobar syndrome. Azygos and hemiazygos continuation of the IVC is rare especially when it is not associated with congenital heart disease. |
" |
" The Greek root ""zyg"" refers to a pair. 'A-' means ""not"". Thus, ""azygos"" means ""unpaired"". The azygos vein is unpaired in that there is only one in the body, mostly on the right side. While there is the hemiazygos vein and its accessory on the left side of the body, they are considered tributaries of the azygos vein rather than its left-side equivalent. |
" |
" This terminology is only accurate in some species, such as the human, dog, and cat. Ruminants (such as sheep and cows) have paired azygos veins. |

" |
" In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing. One definition of material toughness is the amount of energy per unit volume that a material can absorb before rupturing. It is also defined as a material's resistance to fracture when stressed. |
