Dry cleaning 
 Natural fibers such as wool, cotton, and silk of lighter colors should not be left in dirty or soiled condition for long amounts of time as they absorb dirt in their texture and are unlikely to be restored to their original color and finish.
Dry cleaning 
 The main reason that washing in water has a different result than dry cleaning is that water is a polar solvent while dry cleaning uses a non-polar solvent.
Dry cleaning 
 A typical wash cycle lasts for 8–15 minutes depending on the type of garments and degree of soiling.
Dry cleaning 
 During the first three minutes, solvent-soluble soils dissolve into the perchloroethylene and loose, insoluble soil comes off.
Dry cleaning 
 It takes approximately ten to twelve minutes after the loose soil has come off to remove the ground-in insoluble soil from garments.
Dry cleaning 
 Machines using hydrocarbon solvents require a wash cycle of at least 25 minutes because of the much slower rate of solvation of solvent-soluble soils.
Dry cleaning 
 At the end of the wash cycle, the machine starts a rinse cycle wherein the garment load is rinsed with fresh distilled solvent from the pure solvent tank.
Dry cleaning 
 This pure solvent rinse prevents discoloration caused by soil particles being absorbed back onto the garment surface from the "dirty" working solvent.
Dry cleaning 
 After the rinse cycle, the machine begins the extraction process, which recovers dry-cleaning solvent for reuse.
Dry cleaning 
 The extraction cycle begins by draining the solvent from the washing chamber and accelerating the basket to 350 to 450 rpm, causing much of the solvent to spin free of the fabric.
Dry cleaning 
 Until this time the cleaning is done in normal temperature, the solvent is never heated in dry cleaning process.
Dry cleaning 
 During the drying cycle, the garments are tumbled in a stream of warm air (60-63°C/140-145°F) that circulates through the basket, evaporating any traces of solvent left after the spin cycle.
Dry cleaning 
 The exhausted warm air from the machine then passes through a chiller unit where solvent vapors are condensed and returned to the distilled solvent tank.
Dry cleaning 
 Modern dry cleaning machines use a closed-loop system in which the chilled air is reheated and recirculated.
Dry cleaning 
 In the early days of dry cleaning, large amounts of perchlorethylene were vented to the atmosphere because it was regarded as cheap and believed to be harmless.
Dry cleaning 
 After the drying cycle is complete, a deodorizing (aeration) cycle cools the garments and removes even more of the solvent, by circulating cool outside air over the garments and then through a vapor recovery filter made from activated carbon and polymer resins.
Dry cleaning 
 Working solvent from the washing chamber passes through several filtration steps before it is returned to the washing chamber.
Dry cleaning 
 The first step is a button trap, which prevents small objects such as lint, fasteners, buttons, and coins from entering the solvent pump.
Dry cleaning 
 The muck is removed regularly (commonly once per day) and then processed to recover solvent trapped in the muck.
Dry cleaning 
 Many machines use "spin disc filters," which remove the muck from the filter by centrifugal force while it is back washed with solvent.
Dry cleaning 
 This filter is made from activated clays and charcoal and removes fine insoluble soil and non-volatile residues, along with dyes from the solvent.
Dry cleaning 
 Finally, the solvent passes through a polishing filter, which removes any soil not previously removed.
Dry cleaning 
 To enhance cleaning power, small amounts of detergent (0.5%-1.5%) are added to the working solvent and are essential to its functionality.
Dry cleaning 
 Since the solvent recovery is less than 100%, and because dry-cleaning does not remove water-based stains well, entrepreneurs have developed the wet cleaning process, which is, in essence, cold-water washing and air drying, using a computer-controlled washer and dryer.
Dry cleaning 
 In general, wet cleaning is still being improved and developed, although low-tech versions of it have been used for centuries.
Dry cleaning 
 It may have a letter P inside to indicate perchloroethylene solvent, or a letter F inside to indicate a hydrocarbon solvent.
Dry cleaning 
 Cooked powder residue is a hazardous waste and will contain solvent, powdered filter material (diatomite), carbon, non-volatile residues, lint, dyes, grease, soils, and water.
Dry cleaning 
 The waste sludge or solid residue from the still contains solvent, water, soils, carbon, and other non-volatile residues.
Dry cleaning 
 Material removed from the bottom of the stills at chlorinated solvent dry cleaning operations are hazardous wastes.
Dry cleaning 
 Perc is classified as a hazardous air contaminant by the United States Environmental Protection Agency and must be handled as a hazardous waste.
Dry cleaning 
 To prevent it from getting into drinking water, dry cleaners that use perc must take special precautions against site contamination.
Dry cleaning 
 When released into the air, perc can contribute to smog when it reacts with other volatile organic carbon substances.
Dry cleaning 
 California declared perchloroethylene a toxic chemical in 1991, and its use will become illegal in that state in 2023.
Dry cleaning 
 Glycol ethers (dipropylene glycol tertiary-butyl ether) (Rynex) (Solvair) — In many cases they are more effective than perchloroethylene (perc).
Dry cleaning 
 Dipropylene glycol tertiary butyl ether (DPTB) has a flashpoint far above current industry standards, so it is not a fire hazzard.
Dry cleaning 
 DPTB can dissolve water-soluble stains as well as (or better than) perc or the other glycol ether dry cleaning solvents presently in commercial use.
Dry cleaning 
 A particular advantage of the DPTB-water solutions of the Rynex product in dry cleaning is that they do not behave like a typical mixture.
Dry cleaning 
 Hydrocarbon — This is most like standard perc dry cleaning, but the processes use hydrocarbon solvents such as Exxon-Mobil’s DF-2000 or Chevron Phillips' EcoSolv.
Dry cleaning 
 Liquid silicone (decamethylcyclopentasiloxane or D5) — is gentler on garments than perc and does not cause color loss.
Dry cleaning 
 Though considerably more environmentally friendly, the price of it is more than double that of perc, and GreenEarth charges an annual affiliation fee.
Dry cleaning 
 Dow Corning conducted toxicity tests that found liquid silicone increases the incidence of tumors in female rats (no effects were seen in male rats).
Dry cleaning 
 But further research concluded that the effects observed in rats are not relevant to humans because the biological pathway that results in tumor formation is unique to rats.(170.6 °F/77 °C flash point).
Dry cleaning 
 Perchloroethylene — In use since the 1940s, perc is the most common solvent, the "standard" for cleaning performance, and most aggressive cleaner.
Dry cleaning 
 It can cause color bleeding/loss, especially at higher temperatures, and may destroy special trims, buttons, and beads on some garments.
Dry cleaning 
 Better for oil-based stains (which account for about 10% of stains) than more common water-soluble stains (coffee, wine, blood, etc.).
Dry cleaning 
 Liquid CO2 — Consumer Reports rated this method better than conventional methods, but the Drycleaning and Laundry Institute commented on its "fairly low cleaning ability" in a 2007 report.
Dry cleaning 
 Another industry certification group, America's Best Cleaners, counts CO2 cleaners among its members.
Dry cleaning 
 Machinery is expensive—up to $90,000 more than a perc machine, making affordability difficult for small businesses.
Dry cleaning 
 Some cleaners with these machines keep traditional machines on-site for the heavier soiled textiles.
Dry cleaning 
 CO2 cleaning is also used for fire- and water-damage restoration due to its effectiveness in removing toxic residues, soot and associated odors of fire.
Dry cleaning 
 The environmental impact is very low; Carbon dioxide is almost entirely nontoxic, it does not persist in clothing or in the environment, and its greenhouse gas potential is lower than that of many organic solvents.
Dry cleaning 
 Computer-controlled dryers and stretching machines ensure that the fabric retains its natural size and shape.
Dry cleaning 
 Wet cleaning is claimed to clean a majority of "dry clean only" garments safely, including leather, suede, most tailored woolens, silk, and rayon. (
Dry cleaning 
 Most perc cleaners use wet cleaning on some garments, but there are only about 20 exclusive wetcleaners in the U.S.
Dry cleaning 
 Various commercial products on the marketplace today, such as Procter & Gamble's Dryel, allow elements of the dry cleaning process to be performed in the household using home laundry machines.
Dry cleaning 
 Though not the complete process that would be performed by a professional dry cleaner, they allow the convenience of home laundry and work for certain types of garments.
Evolution of cetaceans 
 The vertical movement of their spines, characteristic more of a running mammal than of the horizontal movement of fish.
Evolution of cetaceans 
 The question of how land animals evolved into ocean-going leviathans was a mystery until recent discoveries in Pakistan revealed several stages in the transition of cetaceans from land to sea.
Evolution of cetaceans 
 After many years when palaeontologists thought whales had evolved from mesonychids, DNA sequence analysis showed the closest relationship was with artiodactyls, the even-toed ungulates.
Evolution of cetaceans 
 The most recent hypothesis is that hippos and whales shared a common semi-aquatic ancestor which branched off from other Artiodactyls around 60 million years ago (mya).
Evolution of cetaceans 
 It belongs to the artiodactyls family Raoellidae, and is believed to be the closest sister group of Cetacea.
Evolution of cetaceans 
 About the size of a raccoon or domestic cat, this herbivorous creature shared some of the traits of whales.
Evolution of cetaceans 
 It also showed signs of adaptations to aquatic life, including a thick and heavy outer bone coating.
Evolution of cetaceans 
 This is similar to the bones of modern creatures such as the hippopotamus, and reduces buoyancy so that they can stay underwater.
Evolution of cetaceans 
 This suggests a similar survival strategy to the African mousedeer or water chevrotain which, when threatened by a bird of prey, dives into water and hides beneath the surface for up to four minutes.
Evolution of cetaceans 
 Scientists from the University of Plymouth studied many animals that dive and hold their breath, from insects to whales, and they found that larger animals can hold their breath longer than smaller animals because they can store more oxygen for their size, and this difference was much bigger for warm-blooded animals than for cold-blooded animals.
Evolution of cetaceans 
 They said this may be why modern whales and extinct diving animals like plesiosaurs became so large.
Coal ball 
 A Coal ball is a permineralised life form that is full of calcium, magnesium and occasionally iron sulfide.
Coal ball 
 In 1855, two English scientists, Joseph Dalton Hooker and Edward William Binney, found coal balls in England.
Coal ball 
 Since then, coal balls have been found in other countries and several theories on their formation have been proposed.
Coal ball 
 In 1962, Sergius Mamay and Ellis Yochelson found signs of marine animal remains in North American coal balls.
Coal ball 
 The quality of the preservation of organic material depends on the speed of the burial process and the degree of compression before undergoing permineralisation.
Coal ball 
 Generally, coal balls resulting from remains that have a quick burial with little decay and pressure have a higher preservation degree.
Paul Flory 
 He won the Nobel Prize in Chemistry in 1974 "for his fundamental achievements, both theoretical and experimental, in the physical chemistry of macromolecules."
Paul Flory 
 Flory received a bachelor's degree from Manchester College (Indiana) in 1931 and a Ph.D. from the Ohio State University in 1934.
Paul Flory 
 Flory's earliest work in polymer science was in the area of polymerization kinetics at the DuPont Experimental station.
Paul Flory 
 Most chemists studying condensation polymerization believed that the reactivity of the end group decreased as the macromolecule grew.
Paul Flory 
 In 1938, after Carothers' death, Flory moved to the Basic Science Research Laboratory at the University of Cincinnati.
Paul Flory 
 There he developed a mathematical theory for the polymerization of compounds with more than two functional groups.
Paul Flory 
 In 1943, he left to join the research laboratories of Goodyear Tire and Rubber Company as head of a group on polymer fundamentals.
Paul Flory 
 In the Spring of 1948 Peter Debye, then chairman of the chemistry department at Cornell University, invited Flory to give the annual Baker Lectures.
Paul Flory 
 At Cornell, Flory expanded and refined his Baker Lectures into his best work (magnum opus), Principles of Polymer Chemistry which was published in 1953 by Cornell University Press.
Paul Flory 
 This quickly became a standard text for all workers in the field of polymers, and is still widely used to this day.
Paul Flory 
 Excluded volume" refers to the idea that one part of a long chain molecule can not occupy space that is already occupied by another part of the same molecule.
Paul Flory 
 Excluded volume causes the ends of a polymer chain in a solution to be further apart (on average) than they would be were there no excluded volume.
Paul Flory 
 The recognition that excluded volume was an important factor in analyzing long-chain molecules in solutions provided an important conceptual breakthrough.
Paul Flory 
 It also led to the concept of the theta point, the set of conditions at which an experiment can be conducted that causes the excluded volume effect to be neutralized.
Paul Flory 
 At the theta point, the chain reverts to ideal chain characteristics – the long-range interactions coming from the excluded volume are eliminated.
Paul Flory 
 This allows experimenters to more easily measure short-range features such as structural geometry, bond rotation potentials, and steric interactions between near-neighboring groups.
Paul Flory 
 Flory taught another advantage of performing the experiment at the theta point: the chain dimension in polymer melts would have the size computed for a chain in ideal solution.
Paul Flory 
 In modeling the position vectors of atoms in macromolecules it is often necessary to convert from Cartesian coordinates (x,y,z) to generalized coordinates.
Paul Flory 
 For an example, a peptide bond can be described by the x,y,z positions of every atom in this bond or the Flory convention can be used.
Paul Flory 
 A three-dimensional structure can be described using the Flory convention by applying a vector conversion from the Cartesian coordinates to the generalized coordinates.
Paul Flory 
 He was awarded the Nobel Prize in Chemistry in 1974 "for his fundamental achievements, both theoretical and experimental, in the physical chemistry of macromolecules."

 Interstellar extinction is when the electromagnetic radiation of an astronomical object is blocked and/or scattered by other astronomical objects and cosmic dust.
Masala (movie genre) 
 It is used for  a style of Indian movies where there is a mix of various styles of movies in one movie.
Masala (movie genre) 
 This movie style is used very often in South Indian films as it helps make the movies appeal to more viewers.
Informal economy 
 The informal economy is that part of economy which is not reported in official statistics such as the gross domestic product of a country.
Informal economy 
 People working in this form of economy have no social benefits or social security, which are usually only given by the state to those who have made tax contributions.
Informal economy 
 Usually, most people working in this form of economy are women; they work in the most erratic and corrupt segments of the job market.
Informal economy 
 There are two main reasons why this is the case: First, the kind of employment that is available caters mostly to women.
Informal economy 
 Secondly, most women either work from home, because they also have to take care of children, or they work as street vendors; both of these kinds of work are classified in the informal sector.
Informal economy 
 What is more, most people at the top positions of the sector are men, and most people in the bottom positions are women.
Informal economy 
 For example, very few women are employers who hire others and more women are likely to be involved in smaller scale operations.

Sorption 
 When two chemical substances come in contact with each other, through what is called a phase, they will interact with each other in that phase.
Sorption 
 If a substance accumulates within a phase this is called absorption, if the same process happens on the interface, it is called adsorption.
Sorption 
 In the year 1909, James William McBain introduced the word Sorption to describe such a process, in the case where it is not easy or meaningful to make a difference between absorption and adsorption.
Sorption 
 Examples of where the concept of sorption is important are measuring the pollution of the environment; using sorption it is possible to bind pollutants to small particles in the air (called aerosols), or in the soil (where they bind to colloids).
Sorption 
 Machines and processes that use sorption include the absorption refrigerator and solar air conditioning.

 A major breakthrough in the understanding of materials occurred in the late 19th century, when the American scientist Josiah Willard Gibbs showed that the physical  properties of a material were related to its atomic structure.
Materials science 
 Important elements of modern materials science are a product of the space race: the understanding and engineering of the metallic alloys, and silica and carbon materials, used in the construction of space exploration vehicles.
Materials science 
 Materials science is now linked to the development of plastics, semiconductors, ceramics, polymers,  magnetic materials, medical implant materials and biological materials.
Materials science 
 The material scientist/engineer also deals with the extraction of materials and their conversion into useful forms.
Materials science 
 So, ingot casting, foundry techniques, blast furnace extraction, and electrolytic extraction are all part of the required knowledge of a metallurgist/engineer.
