Emery Board
A nail file is a tool used to gently grind down and shape the edges of nails. They are often used in manicures and pedicures after the nail has been trimmed using appropriate nail clippers. Nail files may either be emery boards, ceramic, glass, crystal, plain metal files or metal files coated with corundum. A nail drill is a powered rotary tool, which is used by a nail technician to file nails. Materials Emery board Emery boards are small flat long objects which have emery or emery paper glued to them, making them both abrasive and flexible, used for fingernail and toenail care. They are used by manicurists to shape and smooth the nail during manicure and pedicure sessions. Emery boards are inexpensive and disposable, making them a sanitary alternative to metal nail files. The emery board was first patented by J. Parker Pray of New York in 1883. Emery boards are generally less abrasive than metal nail files, and hence, emery boards may take longer to file down nails than ...

Baseball
Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over the course of several plays, with each play generally beginning when a player on the fielding team, called the pitcher, throws a ball that a player on the batting team, called the batter, tries to hit with a bat. The objective of the offensive team (batting team) is to hit the ball into the field of play, away from the other team's players, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called " runs". The objective of the defensive team (referred to as the fielding team) is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate (the place where the player started as a batter). The principal objective of the batting team is to have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nail Buffing
Nail buffing is the act of polishing the nail using buffers of successively finer grit in order to make nails look more consistent and shiny. A paste is used to fill ridges on nail surfaces. Technique * The emery board nail file should not be used to buff the surface of the nails. They are meant only to shape them from the side. * The medium grit can be used to smooth ridges and surface irregularities. This can be done before applying nail polish or as a first step before finer buffing. * The fine-grained buff is used to smooth the nail to a matte surface. * The finest finishing grit gives the nails a glossy shine. Traditionally, a buffing cream and chamois skin have been used. Modern instruments are much more efficient and are similar in appearance to a large rubber eraser, with different sides for different levels of coarseness. As buffing is gentle surface abrasion, it should not be performed too strongly or too often or thinning of the nail may result. In manicure ...

Pumice
Pumice (), called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough-textured volcanic glass, which may or may not contain crystals. It is typically light-colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker vesicle walls, and being dark colored and denser.Jackson, J.A., J. Mehl, and K. Neuendorf (2005) ''Glossary of Geology'' American Geological Institute, Alexandria, Virginia. 800 pp. McPhie, J., M. Doyle, and R. Allen (1993) ''Volcanic Textures A guide to the interpretation of textures in volcanic rocks'' Centre for Ore Deposit and Exploration Studies, University of Tasmania, Hobart, Tasmania..198 pp. Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solubi ...

Marie Antoinette
Marie Antoinette Josèphe Jeanne (; ; née Maria Antonia Josepha Johanna; 2 November 1755 – 16 October 1793) was the last queen of France before the French Revolution. She was born an archduchess of Austria, and was the penultimate child and youngest daughter of Empress Maria Theresa and Emperor Francis I. She became dauphine of France in May 1770 at age 14 upon her marriage to Louis-Auguste, heir apparent to the French throne. On 10 May 1774, her husband ascended the throne as Louis XVI and she became queen. Marie Antoinette's position at court improved when, after eight years of marriage, she started having children. She became increasingly unpopular among the people, however, with the French ''libelles'' accusing her of being profligate, promiscuous, allegedly having illegitimate children, and harboring sympathies for France's perceived enemies—particularly her native Austria. The false accusations of the Affair of the Diamond Necklace damaged her reputation further ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass Nail File
A glass nail file is a nail file with an abrasive surface made of glass, that is used to gently grind down and shape the edges of fingernails. They are often used in manicures and pedicures after the nail has been trimmed using nail clippers. Origin In 1997, a new technology for making glass nail files was invented in the Czech Republic, using hardened Bohemian glass Bohemian glass, also referred to as Bohemia crystal, is glass produced in the regions of Bohemia and Silesia, now parts of the Czech Republic. It has a centuries long history of being internationally recognised for its high quality, craftsmanship, ..., by Dalibor Blažek from Blažek Glass s.r.o company. The special procedure of thermal hardening resulted in advantages such as excellent shock-proofness and an extremely durable polishing surface. It had a fine-grained steady abrasive surface created by etching in a solution of acids, which allowed grinding nails without any pain or damaging the fingernail structur ...

Major League Baseball
Major League Baseball (MLB) is a professional baseball organization and the oldest major professional sports league in the world. MLB is composed of 30 total teams, divided equally between the National League (NL) and the American League (AL), with 29 in the United States and 1 in Canada. The NL and AL were formed in 1876 and 1901, respectively. Beginning in 1903, the two leagues signed the National Agreement and cooperated but remained legally separate entities until 2000, when they merged into a single organization led by the Commissioner of Baseball. MLB is headquartered in Midtown Manhattan. It is also included as one of the major professional sports leagues in the United States and Canada. Baseball's first all-professional team, the Cincinnati Red Stockings, was founded in 1869. Before that, some teams had secretly paid certain players. The first few decades of professional baseball were characterized by rivalries between leagues and by players who often jumped from one te ...

Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier than air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simu ...

Cricket
Cricket is a bat-and-ball game played between two teams of eleven players on a field at the centre of which is a pitch with a wicket at each end, each comprising two bails balanced on three stumps. The batting side scores runs by striking the ball bowled at one of the wickets with the bat and then running between the wickets, while the bowling and fielding side tries to prevent this (by preventing the ball from leaving the field, and getting the ball to either wicket) and dismiss each batter (so they are "out"). Means of dismissal include being bowled, when the ball hits the stumps and dislodges the bails, and by the fielding side either catching the ball after it is hit by the bat, but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease in front of the wicket. When ten batters have been dismissed, the innings ends and the teams swap roles. The game is adjudicated by two umpires, aided by a third umpire and match referee ...

Callus
A callus is an area of thickened and sometimes hardened skin that forms as a response to repeated friction, pressure, or other irritation. Since repeated contact is required, calluses are most often found on the feet and hands, but they may occur anywhere on the skin. Some degree of callus, such as on the bottom of the foot, is normal. Calluses are generally not harmful and help prevent blisters, as well as offering protection. However, excessive formation may sometimes lead to other problems, such as a skin ulceration or infection, or cause the affected person to try to offload the affected painful area, which can place excessive stress on the asymptomatic side. Rubbing that is too frequent or forceful will cause blisters, as opposed to calluses, to form. Cause Normally, a callus will form on any part of the skin exposed to excess friction over a long period of time. Activities that are known for causing calluses include (but are not limited to) construction work, many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
