Flame resistance is the characteristic of a fabric that causes it not to burn in air. Flame resistance is often confused with flame retardant which is a term used to describe a chemical substance that imparts flame resistance on fabric. The most commonly used test method for measuring flame resistant (FR) fabrics is ASTM D6413* Standard Test Method for Flame Resistance of Textiles (Vertical Test) (formerly; Method 5903.1 of Federal Test Method Standard 191A). The test uses an enclosed cabinet in

Shrinkage is the contraction in the dimension of the fabric due to usage. These are the reasons for shrinkage: • In case of a fabric‚ the warp yarns are under much strain due to interlacement than the weft yarns. Hence when a fabric is allowed to shrink‚ the warp yarn shrinkage will be more than weft yarns. • To overcome this fabric is extended in widthwise to some extent in the stenter machine during the finishing process. Then it is subjected to the preshrink process. Various mechanical

Nursing practice Abstract Nursing theorist Virginia Henderson (1897-1996)‚ often referred to as the “First Lady of Nursing”‚ developed a nursing model based on the 14 components of activities of daily living. The paper discusses the importance of applying these components to the nursing practice. She emphasized the importance of increasing the patient’s independence so that progress after hospitalization would not be delayed (Henderson 1991). Henderson’s Theory and the main concepts are discussed

Deep ecology is a way of life. A way of life that is shifting the way we view ourselves as humans. Deep ecology is the means of shifting the value of humans to non-human nature. Humans can no longer look at themselves as the sole entity of the ecosystem‚ but part of a whole that needs each part to successfully work. Fritjof Capra believes that shifting our views from the old world anthropocentric to new world non-anthropocentric is the key to the survival of the human race. Having anthropocentric

Ecology Of Crime There are many patterns in the crime rate that seem to be linked to temporal and ecological factors. Crimes usually happen more often‚ and‚ or more less according to the day‚ season‚ climate‚ temperature‚ population density‚ and region. For example‚ a person is more likely to be assaulted at midnight when the temperature exceeds 90 degrees than when to temperature is 10 degrees below zero. Therefore‚ a criminal is more likely to commit a crime when the time of day‚ season‚ and

Ecology Lab Report 4/17/12 Abstract Sampling Stomatal Densities of Various Species of Plants The importance of stomata is the fact that they control the intake of carbon dioxide and the loss of water in plants. The ratio of intake to loss creates a better picture of which plants adapt would to their environment and which would not. Eight different plant species were sampled the stomatal densities and compared them to their environments. The densities were recorded for each species
