Query: What's the purpose of root?
In mathematics, a square root of a number a is a number y such that y2 = a; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is a.[1] For example, 4 and −4 are square roots of 16 because 42 = (−4)2 = 16. Every nonnegative real number a has a unique nonnegative square root, called the principal square root, which is denoted by √a, where √ is called the radical sign or radix. For example, the principal square root of 9 is 3, which is denoted by √9 = 3, because 32 = 3 · 3 = 9 and 3 is nonnegative. The term (or number) whose square root is being considered is known as the radicand. The radicand is the number or expression underneath the radical sign, in this example 9.
The tensile root strength of a range of diameters over a range of species has been tested in the laboratory and has been found to be approximately 5 – 60MN/m2. In order for the root to actually enhance slope stability the root must have sufficient embedment and adhesion with the soil. The way that roots interact with the soil is intricate but for engineering purposes the available force contributions may be measured with in situ pull out tests.
The root zone file is a small (about 2MB) data set whose publication is the primary purpose of root name servers.
The roots, or parts of roots, of many plant species have become specialized to serve adaptive purposes besides the two primary functions, described in the introduction.
On December 17, 2010, DirecTV Sports Networks announced that its four Fox Sports Networks-affiliated regional outlets would be relaunched under the "Root Sports" brand. The network officially rebranded as "Root Sports Northwest" on April 1, 2011, with "The Dan Patrick Show" as the first program under the new Root Sports branding. For nominal purposes, the Root Sports networks continued to carry programming distributed mainly to the Fox Sports regional networks to provide supplementary sports and entertainment programming.
Knowledge of the uses and purposes of the barbasco tuber was highly stratified and barbasqueros often did not know the true purpose of the root they were gathering: they were frequently told that it was used for soap. The acopio owners knew more about the process and eventually invented ways of improving the diosgenin concentration in roots collected by adding different solvents to the tubers before shipping them to the beneficios.
The purpose of the root cap is to enable downward growth of the root, with the root cap covering the sensitive tissue in the root. Also, the root cap enables geoperception or gravitropism. This allows the plant to grow downwards (with gravity) or upwards (against gravity).
For one year during this period Free River Press ran a Great Books seminar funded by the Tennessee Humanities Council. One of the seminar's purposes was to investigate what several traditional cultures said constituted full humanity. Wolf's premise was that our culture has no shared adequate idea of what constitutes full humanity and therefore has created institutions, such as schools and work places, that are deforming us. This is the root of the drug and alcohol problem which in turn is major cause of homelessness. The seminar mixed homeless and non-homeless participants.
Bieber performed "What Do You Mean?" live for the first time at the 2015 MTV Video Music Awards on August 30, 2015. He performed the track on "The Tonight Show Starring Jimmy Fallon", accompanied by The Roots and featuring a guest verse from Black Thought. Bieber also performed "What Do You Mean?" on "The Today Show" along with 5 other songs from his album "Purpose": "Sorry", "Love Yourself", "The Feeling", "No Pressure" and "Company" (which was performed for the first time). The song was performed on the telecast "Think It Up!" which was broadcast on September 11. On September 29, Bieber performed the song on season 7 of X Factor Australia. "What Do You Mean?" was performed at the 2015 MTV Europe Music Awards on October 25. Moreover, the song was also included on the set list for the Purpose World Tour.
International treaties have influenced the development of laws affecting rooting. The 1996 World Intellectual Property Organization (WIPO) Copyright Treaty requires nations party to the treaties to enact laws against DRM circumvention. The American implementation is the Digital Millennium Copyright Act (DMCA), which includes a process for establishing exemptions for non-copyright-infringing purposes such as rooting. The 2001 European Copyright Directive implemented the treaty in Europe, requiring member states of the European Union to implement legal protections for technological protection measures. The Copyright Directive includes exceptions to allow breaking those measures for non-copyright-infringing purposes, such as to run alternative software, but member states vary on the implementation of the directive.
Most Unix and Unix-like systems have an account or group which enables a user to exact complete control over the system, often known as a root account. If access to this account is gained by an unwanted user, this results in a complete breach of the system. A root account however is necessary for administrative purposes, and for the above security reasons the root account is "seldom" used for day to day purposes (the sudo program is more commonly used), so usage of the root account can be more closely monitored.
It is not fully known what evolutionary purpose perforation serves, but there are several possibilities. Perforation could serve the purpose of reducing the chances of leaves tearing in high winds or it could help to maximize the amount of rain that's able to reach the plant's roots. It could help to cool the plant by producing turbulence around the leaf. Another possibility is that perforation is a defense against herbivory. The holes might make the leaf look less enticing to herbivores.
"What is evil? Killing is evil, lying is evil, slandering is evil, abuse is evil, gossip is evil: envy is evil, hatred is evil, to cling to false doctrine is evil; all these things are evil. And what is the root of evil? Desire is the root of evil, illusion is the root of evil." Gautama Siddhartha, the founder of Buddhism, 563–483 BC.
In February 2009, Spence, along with Haley Rushing authored "Its Not What You Sell, Its What You Stand For", providing a primer to a brand management model pioneered by GSD&M called "Purpose Based Branding." According to Spence, "In a company without purpose, people have no idea what they're really there to do. They often look to the competition to decide what to do rather than navigate by their own sense of what's right. With a purpose in place an organization knows its reason for being and is driven to perform and innovate. Purpose sets you apart from the competition, authenticates your brand, inspires passion in your people and helps you achieve the impossible."
For computing these real or complex factorizations, one has to know the roots of the polynomial. In general, they may not be computed exactly, and only approximative values of the roots may be obtained. See Root-finding algorithm for a summary of the numerous efficient algorithms that have been designed for this purpose.
There was at one time a hamlet in Greenfield called Root Creek on the bank of what was locally called "Root Creek" rather than "Root River".
In the early 1990s, Ed Crowley retired from his family-owned soda company with the purpose of crafting “a root beer for connoisseurs.” Crowley began developing his root beer based on old recipes his family had produced in the 1920s. After years of development, Virgil’s Root Beer hit shelves in 1994.
In UNIX-like operating systems, each process has its own idea of what the root directory is. For most processes this is the same as the system's actual root directory, but it can be changed by calling the chroot system call. This is typically done to create secluded environment to run software that requires legacy libraries and sometimes to simplify software installation and debugging. Chroot is not meant to be used for enhanced security as the processes inside can break out. FreeBSD offers a stronger jail() system call that enables operating-system-level virtualization and also serves security purposes to restrict which files a process may access to just a subset of the file system hierarchy.
The practice which monks in the tradition generally begin with are meditations on what Ajaan Mun called the five "root meditation themes": the "hair of the head", "the hair of the body", the "nails", the "teeth", and the "skin". One of the purposes of meditating on these externally visible aspects of the body is to counter the infatuation with the body, and to develop a sense of dispassion. Of the five, the skin is described as being especially significant. Ajaan Mun writes that "When we get infatuated with the human body, the skin is what we are infatuated with. When we conceive of the body as being beautiful and attractive, and develop love, desire, and longing for it, it's because of what we conceive of the skin."
The Dahurican roots are harvested twice a year during the summer and autumn seasons. Its cylindrical roots must be harvested before the plant's stalk emerges. The leaves are removed, the side roots are trimmed, and the roots are thinly sliced, longitudinally. Afterwards, the sliced roots are dried under the sun. In Suining, 70% of its usage are for general purposes whereas 100% of its usage are for medicinal purposes. The roots are also harvested and cultivated in Taiwan, Japan, and Korea.
Example of physical roots:
Action roots point out an activity by a living and sometimes intentional participant. Some action roots indicate the direction of that action with respect to another participant; others denote a participant as involved with the action but not the end receiver. Rather than having the action root modified, Kankanaey roots are very specific as to what the action is. Many roots indicate the receiver of the action.
The Saved Sect believe the majority of Muslims living in the Western world are forgetting their roots, and sees their primary purpose as being to remind the Ummah of what they regard as true Islamic values.
The E root system is a rank 8 root system containing 240 root vectors spanning R. It is irreducible in the sense that it cannot be built from root systems of smaller rank. All the root vectors in E have the same length. It is convenient for a number of purposes to normalize them to have length . These 240 vectors are the vertices of a semi-regular polytope discovered by Thorold Gosset in 1900, sometimes known as the 4 polytope.
The Homestead, a building named and bought by Oren Root in the 1850s, was built adjacent to the Root Glen. Oren and his wife Grace decided to plant various trees, shrubs, and flowers around the building. Then Oren's son Elihu Root inherited the property, and the Roots expanded the gardens. In 1937 Edward Root took over the garden from his father. Grace Root established the Root Glen Foundation after her husband died, which was established to use the land for educational purposes and to promote interest in the study of birds. In 1971, the foundation dissolved and Grace decided to give ownership to Hamilton College. The Root Glen is now maintained by the horticultural grounds staff of the college, and an advisory committee is responsible for the selection of new shrubs and flowers as needed.
Root-cause analysis is a formal problem-solving process and a critical component of Problem Management. Once a problem (or potential problem) has been identified, the root cause analysis process begins. The purpose of a root cause analysis is two-fold:Classic root-cause analysis methods include the 5-whys and "Ishikawa diagram" or fishbone diagram. Others have since developed more advanced root cause analysis methodologies, some with corresponding software applications.
