	Cohesion - Wikipedia, the free encyclopedia
		Cohesion (computer science): a measure of how well the lines of source code within a module work together to provide a specific piece of functionality.
		Cohesion (linguistics): the linguistic elements that make a discourse semantically coherent.
		Cohesion (structural): the sociological and graph theoretical conception and measurement for maximal group or graphical boundaries where related elements cannot be disconnected except by removal of a certain minimal number of other nodes

	Cohesion (chemistry) - Wikipedia, the free encyclopedia
		Cohesion or cohesive attraction or cohesive force in chemistry is the intermolecular attraction between like-molecules.
		The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.
		For example, the molecules of a water droplet are held together by cohesive forces, and the especially strong cohesive forces at the surface constitute surface tension.

		Cohesion and adhesion phenomena are two effects seen mainly where liquids are in the picture.
		This means that the cohesive forces within the mercury atoms is higher than the adhesive forces between the mercury atoms and glass.
		The hardness of a diamond is due to the strong cohesive forces between the carbon atoms of which it is made.

	Team Chemistry
		As a matter of fact, a team’s chemistry, or level of cohesion as it is more formally referred, is an ever-changing group of dynamic that comes in a couple of different forms, and can be learned and improved with practice just like a hitter’s ability to take the ball the other way.
		As I mentioned before, team chemistry, or team cohesion, can be defined as a group dynamic that occurs when members of the team work together and make a united effort to accomplish the goals and objectives of the collective whole.
		One more thing about cohesion and performance: It appears that the link between a team’s success and its subsequent chemistry is stronger than the link between the team’s initial chemistry and their success early on in the season.

		Adhesion between glass and water causes the water to rise along a glass wall until this force is balanced by the cohesive force acting to minimize the liquid's surface area (Surface Tension).
		Organic Chemistry is the study of carbon compounds.
		On the basis of its chemistry and the arrangement of its atoms, a crystal falls into one of 32 classes; these in turn are grouped into seven systems according to the relationships of their axes.

	Cohesion -- Sport Psychology with Karlene Sugarman, M.A.
		Cohesion is the total field of forces which act on members to remain in a particular group (Festinger, Schacter, & Back, 1950).
		A cohesive team has well-defined roles and group norms, common goals, a positive team identity, a good working relationship, shared responsibility, respect, positive energy, trust, a willingness to cooperate, unity, good communication, pride in membership, and synergy.
		Another indicator of the amount of cohesiveness in a team is the frequency of statements of we and our, in contrast to statements of I, me and mine.

		Coaches start planning for chemistry the moment they select a team, that can mean they send some superb athletes home.
		Team cohesion represents a multidimensional process involving specific coaching behaviors as well as the interactions among coach, team, individual team members and overall sport context (Carron, 1982, 1984).
		It was a big year for us, because we were the pre season favorites to win the state championship, and coach wasn't going to let this player destroy the teams chances.

	JCE 1996 (73) 1130 [Dec] Theme-Based Bidisciplinary Chemistry Laboratory Modules
		A thematic approach to each of the two introductory chemistry laboratory sequences, general and organic chemistry, not only provides an element of cohesion but also stresses the role that chemistry plays as the "central science" and emphasizes the intimate link between chemistry and other science disciplines.
		Thus, in general chemistry the rubric "Environmental Chemistry" affords connections to the geosciences, whereas experiments on the topic of "Plant Assays" bridge organic chemistry and biology.
		In the spring of 1996, organic chemistry students synthesized the amide derivatives of a number of auxins via the acid chloride intermediate, which is more efficiently prepared using oxalyl chloride (40-60% overall yield) instead of thionyl chloride (20-40% overall yield), or via nitrile hydrolysis (72-99% yield).

		Social cohesion describes how well team members get along with each other; task cohesion is how well team members work together and actively support each other.
		A team that is young, immature and inexperienced will benefit from social cohesion: They will need to learn to like each other and feel comfortable around their teammates.
		Both kinds of cohesion are greatly dependent on group morale and cooperation; a team is cohesive only to the extent to which it meets the needs of its individual members.

		Mechanical rigidity of molecules and effects such as limited compressibility of matter arise from repulsive exchange forces.
		Long-range forces, or van der Waals forces as they are also called, are attractive and account for a wide range of physical phenomena, such as friction, surface tension, adhesion and cohesion of liquids and solids, viscosity, and the discrepancies between the actual behavior of gases and that predicted by the ideal gas law.
