Cohesion (chemistry)
In chemistry and physics, cohesion (), also called cohesive attraction or cohesive force, is the action or chemical property, property of like molecules sticking together, being mutually attractive. It is an intrinsic property of a Chemical substance, 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 an Intermolecular force, electrical attraction that can maintain a macroscopic structure such as a drop (liquid), 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 ...

Cohesion (computer Science)
In computer programming, cohesion refers to the ''degree to which the elements inside a module (programming), module belong together''. In one sense, it is a measure of the strength of relationship between the Method (computer programming), methods and data of a Class (computer programming), 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. Cohesion is an level of measurement#Ordinal_scale, 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 software traits including Robustness (computer science), robustness, reliability, reusability, and understandability. In contrast, low cohesion is associated with undesirable traits such as being difficult to maintain, test, reuse, or understand. Cohesion is often contraste ...

Cohesion (geology)
Cohesion is the component of shear strength of a rock or soil that is independent of interparticle friction. In soils, true cohesion is caused by following: # Electrostatic forces in stiff overconsolidated clays (which may be lost through weathering) # Cementing by Fe2 O3, Ca CO3, Na 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 plant Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with c ...s, or through solution) Typical values of cohesion Cohesion (alternatively called the cohesive strength) is typically measured on the basis of Mohr–Co ...

Cohesion (linguistics)
Cohesion is the grammar, grammatical and Lexicon, lexical linking within a text or sentence (linguistics), sentence that holds a text together and gives it meaning. It is related to the broader concept of coherence (linguistics), 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 (narrative device), ellipsis, substitution, lexical cohesion and grammatical conjunction, conjunction. Referencing There are two referential devices that can create cohesion: *anaphora (linguistics), Anaphoric reference occurs when the writer refers back to someone or something that has been previously identified, to avoid repetition.

Cohesion (social Policy)
Group cohesiveness, also called group cohesion, social harmony or social cohesion, is the degree or strength of bonds linking 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 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 cohesiveness, including its multidimensionality, dynamic nature, instrumental basis, and emotio ...

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 fro ...

Community Cohesion
Community cohesion is a conceptual framework for social policy in the United Kingdom 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 undefined. 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 Ind ...

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 structur ...

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 propertie ...
