In polymer chemistry, a structural unit is a building block of a polymer chain. It is the result of a monomer which has been polymerized into a long chain. There may be more than one structural unit in the repeat unit. When different monomers are polymerized, a copolymer is formed. It is a routine way of developing new properties for new materials.
Stuff Matters: Exploring the Marvelous Materials That Shape Our Man-Made World is a 2014 non-fiction book by the British materials scientist Mark Miodownik. The book explores many of the common materials people encounter during their daily lives and seeks to explain the science behind them in an accessible manner. Miodownik devotes a chapter ...
In the context to structural analysis, a structure refers to a body or system of connected parts used to support a load. Important examples related to Civil Engineering include buildings, bridges, and towers; and in other branches of engineering, ship and aircraft frames, tanks, pressure vessels, mechanical systems, and electrical supporting structures are important.
A structure depends less on the weight and stiffness of a material and more on its geometry for stability. [2] Whatever the condition is, a specific rigidity is necessary for connection designs. The support connection type has effects on the load bearing capacity of each element, which makes up a structural system.
The structure of a DNA molecule is essential to its function. A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. [1] Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and ...
These programs are written in the Scheme programming language, as were the programs in Sussman's earlier computer science textbook, Structure and Interpretation of Computer Programs. Sussman wrote: Classical mechanics is deceptively simple. It is surprisingly easy to get the right answer with fallacious reasoning or without the real understanding.
Emile Durkheim based his sociological concept on 'structure' and 'function', and from his work emerged the sociological approach of structural functionalism. Apart from Durkheim's use of the term structure, the semiological concept of Ferdinand de Saussure became fundamental for structuralism. Saussure conceived language and society as a system ...
Bourdieu's work attempts to reconcile structure and agency, as external structures are internalized into the habitus while the actions of the agent externalize interactions between actors into the social relationships in the field. Bourdieu's theory, therefore, is a dialectic between "externalizing the internal", and "internalizing the external".
