Cohesion (chemistry)
Cohesion (), also called cohesive attraction or cohesive force, is the action or property of like molecules sticking together, being mutually attractive. It is an intrinsic property of a substance that is caused by the shape and structure of its molecules, which makes the distribution of surrounding electrons irregular when molecules get close to one another, creating electrical attraction that can maintain a microscopic structure such as a water drop. Cohesion allows for surface tension, creating a "solid-like" state upon which light-weight or low-density materials can be placed. Water, for example, is strongly cohesive as each molecule may make four hydrogen bonds to other water molecules in a tetrahedral configuration. This results in a relatively strong Coulomb force between molecules. In simple terms, the polarity (a state in which a molecule is oppositely charged on its poles) of water molecules allows them to be attracted to each other. The polarity is due to the ...

Cohesion (computer Science)
In computer programming, cohesion refers to the ''degree to which the elements inside a module belong together''. In one sense, it is a measure of the strength of relationship between the methods and data of a class and some unifying purpose or concept served by that class. In another sense, it is a measure of the strength of relationship between the class's methods and data themselves. Cohesion is an ordinal type of measurement and is usually described as “high cohesion” or “low cohesion”. Modules with high cohesion tend to be preferable, because high cohesion is associated with several desirable traits of software including robustness, reliability, reusability, and understandability. In contrast, low cohesion is associated with undesirable traits such as being difficult to maintain, test, reuse, or even understand. Cohesion is often contrasted with coupling, a different concept. High cohesion often correlates with loose coupling, and vice versa. The software metrics of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cohesion (geology)
Cohesion is the component of Shear strength (soil), shear strength of a Rock (geology), rock or soil that is independent of interparticle friction. In soils, true cohesion is caused by following: # Electrostatic forces in stiff consolidation (soil), overconsolidated clays (which may be lost through weathering) # Cementing by Iron, Fe2Oxygen, O3, Calcium, Ca Carbon, CO3, Sodium, Na Chloride, Cl, etc. There can also be apparent cohesion. This is caused by: # Negative capillary pressure (which is lost upon wetting) # Pore pressure response during undrained loading (which is lost through time) # Root cohesion (which may be lost through logging or fire of the contributing plants, or through Solution (chemistry), solution) Typical values of cohesion Cohesion (alternatively called the cohesive strength) is typically measured on the basis of Mohr–Coulomb theory. Some values for rocks and some common soils are listed in the table below. Apparent cohesion of soil During critical state ...

Cohesion (linguistics)
Cohesion is the grammatical and lexical linking within a text or sentence that holds a text together and gives it meaning. It is related to the broader concept of coherence. There are two main types of cohesion: * grammatical cohesion: based on structural content * lexical cohesion: based on lexical content and background knowledge. A cohesive text is created in many different ways. In ''Cohesion in English'', M.A.K. Halliday and Ruqaiya Hasan identify five general categories of cohesive devices that create coherence in texts: reference, ellipsis, substitution, lexical cohesion and conjunction. Referencing There are two referential devices that can create cohesion: * Anaphoric reference occurs when the writer refers back to someone or something that has been previously identified, to avoid repetition. Some examples: replacing "the taxi driver" with the pronoun "he" or "two girls" with "they". Another example can be found in formulaic sequences such as "as stated previously" or " ...

Cohesion (social Policy)
Group cohesiveness (also called group cohesion and social cohesion) arises when bonds link members of a social group to one another and to the group as a whole. Although cohesion is a multi-faceted process, it can be broken down into four main components: social relations, task relations, perceived unity, and emotions. Members of strongly cohesive groups are more inclined to participate readily and to stay with the group. Definition From Neo-Latin and French , in physics, cohesion means "the force that unites the molecules of a liquid or of a solid". Thereby, there are different ways to define group cohesion, depending on how researchers conceptualize this concept. However, most researchers define cohesion to be task commitment and interpersonal attraction to the group. Cohesion can be more specifically defined as the tendency for a group to be in unity while working towards a goal or to satisfy the emotional needs of its members. This definition includes important aspects of co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cohesion (album)
''Cohesion'' is the fourth studio album by Australian rock band Gyroscope, released through Island Records on 9 April 2010. It peaked at No. 3 on the ARIA Albums Chart. The album's first single "Some of the Places I Know" was released on 1 February 2010, and the second single "Baby, I'm Gettin' Better" was released on 17 May. The third single, What Do I Know About Pain? was released on 1 October 2010. All three songs have had music videos provided for them. The first two singles have peaked within the top 40 of the ARIA Singles Charts. Album history The production of the album was first revealed towards the end of September 2009, when the band announced on their MySpace that they had "packed up their gear and headed to the rolling green hills of Monmouth, Wales to record album #4." They also announced that Gil Norton (Foo Fighters, Pixies) would be producing the album. Gyroscope uploaded "Live Without You" to their MySpace in January 2010, the first song released from t ...

Cohesion (band)
Cohesion are a four-piece indie rock band from Manchester. The group are: *Andrew O'Hara - vocals, guitar. *Kevin McPhillips - lead guitar. *Simon Harrison - bass. *Geoff Burroughs - drums, percussion. The band were formed by O'Hara and McPhillips in 2003. Burroughs joined the duo in 2004, with Harrison completing the line-up in 2005. After a sustained period of playing gigs at local venues, the group have released two EPs independently, ''Cohesion EP'' and ''Shadows In The Shade EP'' (named after a lyric in the song 'Can't Ignore') to critical acclaim in the local press and internet music sites. The band consider their influences to be bands such as The La's, Coldplay, The Flaming Lips, David Bowie, The Beach Boys, amongst others. Reviews of the band have noted the band's distinct 'West Coast' sound. Cohesion are currently residing in Levenshulme, Manchester.

Community Cohesion
Community cohesion is a conceptual framework which attempts to measure the social relationships within a community. It relies on criteria such as: the presence of a shared vision, inclusion of those with diverse backgrounds, equal opportunity, and supportive relationships between individuals. It was introduced in the UK in 2001 after the 2001 England riots. The ideas contained within the framework have been refined a number of times, though the definition remains poorly defined. It has also been criticised as political in nature, with moral imperatives which are not overly helpful. History The concept of community cohesion was established in the United Kingdom following a number of riots and disturbances in England in 2001. Although the term had been used in different contexts previously (in Canada, for example), the first report to employ the term and to propose a new policy framework around it was ''Community Cohesion: The Report of The Independent Review Team''. The report con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structural Cohesion
In sociology, structural cohesion is the conception of a useful formal definition and measure of cohesion in social groups. It is defined as the minimal number of actors in a social network that need to be removed to disconnect the group. It is thus identical to the question of the node connectivity of a given graph in discrete mathematics. The vertex-cut version of Menger's theorem also proves that the disconnection number is equivalent to a maximally sized group with a network in which every pair of persons has at least this number of separate paths between them. It is also useful to know that -cohesive graphs (or -components) are always a subgraph of a -core, although a -core is not always -cohesive. A -core is simply a subgraph in which all nodes have at least neighbors but it need not even be connected. The boundaries of structural endogamy in a kinship group are a special case of structural cohesion. Software Cohesive.blockingis the R program for computing structural c ...

Cohesion Number
The Cohesion number (''Coh'') is a useful dimensionless number in particle technology by which the cohesivity of different powders can be compared. This is especially useful in DEM simulations (Discrete Element Method) of granular materials where scaling of the size and stiffness of the particles are inevitable due to the computationally demanding nature of the DEM modelling. Background In simulation of granular materials, scaling the particle size with regards to the other particles physical and mechanical properties is a challenging job. Especially in simulation of cohesive powders, lack of a robust criterion for tuning the level of the surface energy of the particles can waste enormous amount of time during the process of calibration. The Bond number has been used traditionally in this regards, where the significance of the adhesive force (pull-off force) is compared with the particles gravitational force (weight); nevertheless, the influence of the materials properties, parti ...
