Mechanization

(noun)

The use of heavy machinery to improve production. In the case of agriculture, this included tractors and combine harvesters, which made farms more efficient but displaced unskilled laborers.

Examples of Mechanization in the following topics:

  • Implications of Quantum Mechanics

    • The field of quantum mechanics has been enormously successful in explaining many of the features of our world.
    • Quantum mechanics has also strongly influenced string theory.
    • The application of quantum mechanics to chemistry is known as quantum chemistry.
    • Relativistic quantum mechanics can, in principle, mathematically describe most of chemistry.
    • Explain importance of quantum mechanics for technology and other branches of science

  • Conservation of Mechanical Energy

    • Conservation of mechanical energy states that the mechanical energy of an isolated system remains constant without friction.
    • Conservation of mechanical energy states that the mechanical energy of an isolated system remains constant in time, as long as the system is free of all frictional forces.
    • This equation is a form of the work-energy theorem for conservative forces; it is known as the conservation of mechanical energy principle.
    • The total kinetic plus potential energy of a system is defined to be its mechanical energy (KE+PE).
    • An example of a mechanical system: A satellite is orbiting the Earth only influenced by the conservative gravitational force and the mechanical energy is therefore conserved.

  • Mechanical and Organic Solidarity

    • Mechanical and organic solidarity are concepts referring to different modes of establishing and maintaining social order and cohesion.
    • Durkheim described two forms of solidarity: mechanical and organic, roughly corresponding to smaller and larger societies.
    • Mechanical solidarity refers to connection, cohesion, and integration born from homogeneity, or similar work, education, religiosity, and lifestyle.
    • Normally operating in small-scale "traditional" societies, mechanical solidarity often describes familial networks; it is often seen as a function of individuals being submerged in a collective consciousness.
    • Apply Durkheim's concepts of mechanical and organic solidarity to groups in the real world

  • Curved Arrow Notation

    • A detailed description of the changes in structure and bonding that take place in the course of a reaction, and the sequence of such events is called the reaction mechanism.
    • A reaction mechanism should include a representation of plausible electron reorganization, as well as the identification of any intermediate species that may be formed as the reaction progresses.
    • It is now common practice to show the movement of electrons with curved arrows, and a sequence of equations depicting the consequences of such electron shifts is termed a mechanism.
    • In general, two kinds of curved arrows are used in drawing mechanisms:

  • Rate Laws for Elementary Steps

    • It is important to keep in mind that every reaction mechanism is simply a proposed version of what might be occurring at the molecular level; even if a mechanism agrees with experimental results, it is impossible to prove a reaction mechanism for certain.
    • The sum of each elementary step in a reaction mechanism must yield the overall reaction equation.
    • The rate-determining step is the slowest step in a reaction mechanism.
    • Upon further analysis, the mechanism is given as:
    • The molecularity of an elementary step in a reaction mechanism determines the form of its rate law.

  • Durkheim's Mechanical and Organic Solidarity

    • Mechanical solidarity is found in less structurally complex societies while organic solidarity emerges in industrialized societies.
    • As part of his theory of the development of societies in, The Division of Labour in Society (1893), sociologist Emile Durkheim characterized two categories of societal solidarity: organic and mechanical.
    • In a society exhibiting mechanical solidarity, its cohesion and integration comes from the homogeneity of individuals.
    • Mechanical solidarity normally operates in "traditional" and small-scale societies, and it is usually based on kinship ties of familial networks.
    • Give examples for societies held together by mechanical or organic solidarity

  • Shifts Occurring by Addition-Elimination Mechanisms.

  • Work

    • Work performed by a closed system is the energy transferred to another system that is measured by mechanical constraints on the system.
    • In thermodynamics, work performed by a closed system is the energy transferred to another system that is measured by mechanical constraints on the system .
    • Thermodynamic work encompasses mechanical work (gas expansion, ) plus many other types of work, such as electrical.
    • As such, thermodynamic work is a generalization of the concept of mechanical work in mechanics.
    • Analyze the necessity to exclude energy transferred between system as heat from mechanical work

  • Regulatory Mechanisms for Cellular Respiration

    • Cellular respiration can be controlled at each stage of glucose metabolism through various regulatory mechanisms.
    • Various mechanisms are used to control cellular respiration.

  • Epigenetic Alterations in Cancer

    • Common in cancer cells, silencing genes, which occur through epigenetic mechanisms, include modifications to histone proteins and DNA.
    • Silencing genes through epigenetic mechanisms is very common in cancer cells and include modifications to histone proteins and DNA that are associated with silenced genes.
    • Genes involved in the development of many other illnesses, ranging from allergies to inflammation to autism, are also thought to be regulated by epigenetic mechanisms.
    • In cancer cells, silencing genes through epigenetic mechanisms is a common occurrence.
    • Mechanisms can include modifications to histone proteins and DNA associated with these silencing genes.
