sodium | Facts, Uses, & Properties | Britannica

Properties and production. Because sodium is extremely reactive, it never occurs in the free state in Earth's crust. In 1807 Sir Humphry Davy became the first to prepare sodium in its elemental form, applying electrolysis to fused sodium hydroxide (NaOH). Sodium is an important constituent of a number of silicate materials, such as feldspars and micas. .

Educational Research - Traditional VS Action Research

It is a process that integrates practical pursuit, theory and practice, and community-school-based participants to identify practical solutions about a concern. Below are the following purpose and features of action research: Developed in 1940's by a psychologist Kurt Lewin. It is a research process investigating about a problem.

A Theoretical Critique of the Societal Reaction Approach .

reaction approach to deviance contains two fundamentally divergent images of the deviant. The two images are those of a "drifter" versus an "oversocialized conception" of the deviant. These two images are contained within the two fundamental concepts of the societal reaction approach, that of "primary deviance" and "secondary deviance."

Calculating Screw Jacks and Their Operation - Bright Hub .

Screw jacks are devices which has made life easy especially with lifting of heavy loads above the ground levels. Fundamentally two important parameters go hand in hand with the operations of a screw jack, namely the weight which is being elevated and the effort applied external for the purpose. While calculating screw jacks, relating the above two aspects becomes crucially important.
