A chemical peel is a technique used to improve and smooth the texture of the skin. Facial skin is mostly treated, and scarring can be improved. Chemical peels are intended to remove the outermost layers of the skin. To accomplish this task, the chosen peel solution induces a controlled injury to the skin. Resulting wound healing processes begin to regenerate new tissues. The dead skin eventually peels off. The regenerated skin is usually smoother and less wrinkled than the old skin. Some types of chemical peels can be purchased and administered without a medical license; however, people are advised to seek professional help from a dermatologist or plastic surgeon on a specific type of chemical peel before a procedure is performed. Types There are several types of chemical peels. α-hydroxy acid peels Alpha hydroxy acids (AHAs) are naturally occurring carboxylic acids such as glycolic acid, a natural constituent of sugar cane juice, and lactic acid, found in sour milk and tomato juice as well as being produced endogenously during...

A “Risk pool” is a form of risk management that is mostly practiced by insurance companies, which come together to form a pool to provide protection to insurance companies against catastrophic risks such as floods or earthquakes. The term is also used to describe the pooling of similar risks within the concept of insurance. It is basically like multiple insurance companies coming together to form one. While risk pooling is necessary for insurance to work, not all risks can be effectively pooled in a voluntary insurance bracket unless there is a subsidy available to encourage participation.Risk pooling is an important concept in supply chain management. Risk pooling suggests that demand variability is reduced if one aggregates demand across locations because as demand is aggregated across different locations, it becomes more likely that high demand from one customer will be offset by low demand from another. The reduction in variability allows a decrease in safety stock and therefore reduces average inventory. For example, in the centralized distribution system, the warehouse serves all customers, which leads to a reduction in variability measured by either the standard...

A helioscope is an instrument used in observing the sun and sunspots. The helioscope was first used by Benedetto Castelli (1578-1643) and refined by Galileo (1564–1642). The method involves projecting an image of the sun onto a white sheet of paper suspended in a darkened room with the use of a telescope.The first machina helioscopica or helioscope was designed by Christoph Scheiner (1575 –1650) to assist his sunspot observations.In the context of modern astroparticle physics, the term helioscope can also refer to an experiment that seeks to observe hypothetical particles (such as the axion) produced inside the sun. Examples of such helioscope experiments searching for axions include the CERN Axion Solar Telescope and International Axion Observatory.
