Social network analysis

Social network analysis (SNA) is the process of investigating social structures through the use of network and graph theories. It characterizes networked structures in terms of nodes (individual actors, people, or things within the network) and the ties or edges (relationships or interactions) that connect them. Examples of social structures commonly visualized through social network analysis include social media networks, friendship and acquaintance networks, kinship, disease transmission,and sexual relationships. These networks are often visualized through sociograms in which nodes are represented as points and ties are represented as lines.

Social network analysis has emerged as a key technique in modern sociology. It has also gained a significant following in anthropology, biology, communication studies, economics, geography, history, information science, organizational studies, political science, social psychology, development studies, and sociolinguistics and is now commonly available as a consumer tool.

Cascade Range

The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at 14,411 feet (4,392 m).

The Cascades are part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from Cascade volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and a major eruption of Mount St. Helens in 1980. Minor eruptions of Mount St. Helens have also occurred since, most recently from 2004-2008.

Cascade (computer virus)

The Cascade virus is a prominent computer virus that was a resident written in assembly, and it was widespread in the 1980s and early 1990s. It infected .COM files and had the effect of making text on the screen fall down and form a heap in the bottom of the screen. It was notable for using an encryption algorithm to avoid being detected. However one could see that infected files had their size increased by 1701 or 1704 bytes. In response, IBM developed its own anti-virus software.

The virus has a number of variants. Cascade-17Y4, which is reported to have originated in Yugoslavia is almost identical to the most common 1704 byte variant. One byte has been changed, probably due to a random "mutation". This, however, has resulted in a "bug" in the virus. Another mutated variant is also known - it infects the same file over and over.

Henna

Henna (Lawsonia inermis, also known as hina, the henna tree, the mignonette tree, and the Egyptian privet) is a flowering plant and the sole species of the Lawsonia genus. The English name "henna" comes from the Arabic حِنَّاء‎ (ALA-LC: ḥinnāʾ; pronounced [ħɪnˈnæːʔ]) or, colloquially حنا‎, loosely pronounced as /ħinna/.

The name henna also refers to the dye prepared from the plant and the art of temporary body art (staining) based on those dyes (see also mehndi). Henna has been used since antiquity to dye skin, hair and fingernails, as well as fabrics including silk, wool and leather. The name is used in other skin and hair dyes, such as black henna and neutral henna, neither of which is derived from the henna plant.

Historically, henna was used for cosmetic purposes primarily in Ancient India. It was also found to be used in the Arabian Peninsula, South Asia, Carthage and other parts of North Africa, and the Horn of Africa. Bridal henna nights remain an important custom in many of these areas, particularly among traditional families.

Henna (film)

Heena is the name of a 1991 Bollywood film produced and directed by Randhir Kapoor and starring his brother Rishi Kapoor, Ashwini Bhave (both of India) and Zeba Bakhtiyar (of Pakistan) also renowned as Neha Seti. It was shot in Kashmir. This film's project was planned and started by legendary director Raj Kapoor but due to his demise during the filming stage, the remaining portions were directed by his son Randhir Kapoor. Hence, this film is considered as the last film of Raj Kapoor. The film was an Indo-Pak project, hence the dialogues of the film were written by the Pakistani legendary writer Haseena Moin on Raj Kapoor's personal request. The film was a critical and a commercial success and was also India's submission for the Academy Award for Best Foreign Language Film, but was not accepted as a nominee.

Plot

The story revolves around the mistaken straying (due to a car accident which also caused him to suffer amnesia) of Rishi Kapoor into the Pakistani side of Kashmir from his own home in Srinagar .
