In other words, individuals who are extrinsically motivated are driven by external factors such as rewards, recognition, praise, grades, or avoidance of punishment. This … Read more
Adrenal glands are endocrine glands located above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla. Adrenal cortex produces three main types of steroid hormones, mineralocorticoids, glucocorticoids and adrogens. The adrenal medulla is at the center of each adrenal gland, and is surrounded by the adrenal cortex. It … Read more
What is Management by Objectives (MBO)? Management by Objectives (MBO) is a management philosophy and a systematic approach to management that emphasizes the setting of specific, measurable, achievable, relevant, and time-bound (SMART) objectives.

What Is Opening & Closing In Image Processing? Opening and closing are two important operators from mathematical morphology. They are both derived from the fundamental operations of erosion and deletion. Like those operators they are normally applied to binary images, although there are also graylevel versions. Opening is generally used to remove small objects from … Read more
What Is Diffusion? Diffusion is the process whereby the molecules move as a result of their kinetic energy. Diffusion occurs in liquids and gases because their molecules move randomly. The molecules move from a region of higher concentration to a region of lower concentration, down the concentration gradient, until the concentration equalizes throughout the medium. … Read more

What Is Schottky Defect? A Schottky defect is a type of point defect in a crystal lattice named after a German physicist Walter H. Schottky who discovered it. In ionic crystals, this type of point defect forms when oppositely charged ions leave their corresponding lattice sites, creating a pair of vacancy defects. These vacancies are … Read more
