...attachment that resists separation. “Adhesive” as a general term includes cement, mucilage, glue, and paste—terms that are often used interchangeably for any organic material that forms an adhesive bond. Inorganic substances such as portland cement also can be considered adhesives, in the sense that they hold objects such as bricks and beams together through surface attachment, but this article is limited to a discussion of organic adhesives, both natural and synthetic. (http://www.britannica.com/EBchecked/topic/5823/adhesive) Fish glue is often made by heating the skin or bones of fish in water. It can also be made from part of the fish’s air bladder which, in the case of glue made from sturgeon, is called isinglass. Adhesives made from fish, as well as hide glue made from other animals, were sometimes used in ancient Egypt. They are still used in art, for shoe and furniture repair, and to preserve old manuscripts. Hide glue is typically manufactured from the skin of non-oily fish. During medieval times in Europe, fish glue was often used to repair animal-based sheets called parchments, which were used for writing. It was also used in painting materials by some artists in China. Paintings and drawings were often coating with fish glue in the 1800s. While the glue by itself is typically brittle, it can be used along with other materials to restore paintings. Artistic uses for fish glue include its application as a binder, glazing agent, or protective coating for paintings. The...

...to eat glue Posted by Ryan Pilling on Mar 2, 2011 in Interesting Facts | 1 comment In the exciting world of adhesives, glue is the organic side of things. Technically, for something to be a true “glue” it will get its sticky quality from an animal or vegetable ingredient. The classic example is sending an old horse to the great glue factory in the sky. In fact horse hooves, along with bone, hide, and connective tissues, provide collagen as the main ingredient for glue. (in all mammals, including you dear reader, over 25% of the protein content is collagen) The process of turning pony toes into glue is, to boil it down, essentially… boiling it down. The collagen leaks out in a jelly-like form, is collected, and ground into powder. When you’re ready to make antique furniture, you mix it with a bit of water, heat it up, and you’re ready to brush it on your joins. Collagen glue like that has been used for at least 8000 years, and has only been replaced by chemical adhesives for common use in the past century. Vegetable glue, commonly called paste, is an even simpler recipe: starch and water. The starch most commonly used is corn starch, but white flour works as well. When sticking things together, the best adhesive is one that shares chemical properties of the items you want to make stick. That’s why paste works so well with paper. The starch, which is a carbohydrate, is similar to the carbohydrate cellulose that forms the paper. So animal glue is basically...

...Classification of Adhesives: There are two main classes of adhesives: thermoplastic and thermosetting. Thermoplastic sets either my loss of solvent or by cooling. It will soften again by applying the solvent to the glue line or by re-heating. Thermosetting sets and solidifies through a chemical reaction and is irreversible. Adhesives that set at room temperature are known as 'cold-setting' and those that require heating up to a temperature perhaps in the case of pearl glue 40 and others up to 100 degrees C are known as 'hot-setting'. Types of Adhesives: Animal. Known as scotch glue (yes glue!), pearl or hide glue. Made from the hides, hoofs and bones of animals. Available now in cake or more likely supplied in small beads. It is essential for restoration work, veneering and other applications where compatibility with original artefacts is needed. Used extensively in the musical instrument industries. It is for internal use only and has high gap filling properties. Fish glue is also available which is made out of fish offal and skins. Good for small repairs. Not recommended for structural work. Casein. Manufactured from soured, skimmed milk curbs which are dried and crushed into a powder form. General joinery and woodwork use. It may stain some hardwoods and oak is particularly prone to darken. To use the powder it is mixed with cold water into a smooth creamy paste. Developed in WW2 for the manufacture of the Mosquito plane which was largely made...

...Fuller Company repeatedly over many years. The article read: On a sidewalk in San Pedro Sula, Honduras ... a lanky, dark-haired boy [is] sitting w i t h arms curled around his folded legs, staring at the passing traffic. The boy, a nineteenyear-old named Marvin, has been sniffing glue for ten years. Once the leader of a gang of street kids, he now has slurred speech and vacant eyes. A year ago, Marvin began to lose feeling in his legs. Now he can no longer walk. He slides on his butt, spiderlike, through gutters, across streets, and along the sidewalks. Still loyal to their chief, the younger kids in his gang bring Marvin food, carry him to a news stand to spend the night, and make sure he has enough glue to stay high. ... Doctors offer no hope that Marvin will ever w a l k again. Toluene, the solvent in the glue he sniffs, is a neurotoxin known to cause irreparable nerve damage. ... In Honduras, the drug of choice for children is H. B. Fuller’s Resistol, a common shoe-glue made with toluene. Toluene creates the high the children come to crave ... Sniffing the glue is so common ... that the common name f o r street kids is Resistoleros . 1 Marvin was not the only casualty of the toluene-based glue.

...ISEG - BUSINESS ETHICS (Simone de Colle) Pre-Seminar Assignment ‘The parable of the Sadhu’ Q1-Do you think that behaviour of McCoy is morally blameworthy? No, it describes only how people think today, so I think McCoy behaviour is not morally blameworthy; but it will be maybe for other people because it describes a moral dilemma (what is wrong and right) so it depends on personal beliefs and culture. The parable of the Sadhu is a very interesting example of the modern society, where the individual doesn’t really know what he has to do, he doesn’t arrive to take an important decision alone if the others do not support him, especially under mental and physical stress. The parable offers an interesting parallel to modern business situations, because in this case people had to make an important decision immediately, only one person reacted on the right way (Stephen), the other were thinking as individuals with different points of view, values and beliefs. In an organisation a manager personalised the values of the company where all can identify themselves in; in this case it wasn’t a ‘manager’ but only a group of person coming from different cultures. I can say that when in a corporation the members share all together the notion of correct behaviour and culture (so interdependent), it is traduced as a positive force because they are strong and they can act and implement immediately. The individual is lost if he is not supported by a group, it is necessary that the individual...

...of the Proceeding and Judges Writing Decision: The nature of this case is an appeal of a case originally from the Manitoba Court of Appeal, and was brought forward to the Supreme Court of Canada. The judges writing the majority decision were Lamer C.J., La Forest, L’Heureux-Dube, Gonthier, Cory, McLachlin and Iacobucci. The two dissenting judges were Sopinka and Major JJ. The original trial judge was Schulman J. Facts: A woman, who was five months pregnant at the time of trial, was sued by Winnipeg Child and Family Services for custody of the child, and was ordered to be placed into care at the Health Sciences Centre due to the fact that her glue sniffing addiction could potentially harm the nervous system of her unborn child. The woman had three other children at the time, two of which were born with disabilities due to her glue sniffing addiction. The superior court judge presiding determined the case fell under the court’s parens patriae jurisdiction. However, two days later the order was stayed, and set aside on appeal. The Manitoba Court of Appeal eventually decided to allow the appeal of the strike down of the original sentencing by Schulman, and the respondent must refrain from from consuming intoxicating substances and avoid due harm to her unborn child....

...According to Cohen and Inaba (2014), “Inhalants are volatile liquids or aerosol sprays that produce many of the same psychoactive effects as street drugs” (p. 7.2). Inhalants are cheap, fast acting, and quickly accessible on the street, at home, and at work (Cohen & Inaba, 2014). There are several methods of inhalation such as sniffing, huffing, “bagging,” spraying, “balloons and crackers,” and inhaling vaporized alcohol fumes (Cohen & Inaba, 2014). Inhalants have four categories: volatile solvents, aerosols, volatile nitrites, and anesthetics; and each category has an inhalant product (Cohen & Inaba, 2014). Volatile solvents inhalants are gasoline and gasoline additives, airplane glue, rubber cement and other glues, liquid cement, nail polish...

...Inhalants are a wide variety of substances having to due with nitrites, solvents, aerosols and gases that are breathed through the mouth or nose. Many products are found at home or work places, such as cleaning fluids, spray paints, sharpies, etc. Anything with harsh chemicals. They can be art or office supplies. People do not always think of these materials/products to be considered as drugs, but a good majority of people can abuse them in that way. Inhalants are the only class of substance to be abused the most by younger children than by older teens. They can be inhaled by sniffing, snorting, or placing a chemical-soaked rag, to get the fumes directly into their nose or mouth. They can also be inhaled from plastic or paper bags, as well as balloons. Abusers will often continue to inhale the products over several hours, seeing that the “high” does not last but a few minutes. The way inhalants affect the brain is not to different from alcohol effects; slurred speech, dizziness, lack of coordination, light headedness,...

...The Dog, The Family: A household Tale Summary In August Kleinzahler’s description of his childhood years, which seems to center around his dog, a pure bred boxer named Twenty Grand, or Granny for short after a famous racehorse. He identifies how as a member of the household, the dog became more influential in his upbringing and more important than some other members of his family. The constant criticism that Kleinzahler claims he would receive from his parents and grandmother would generally be grounds for the beginning of a depressing memoir. His crazy descriptions of his glue sniffing brother or bookworm sister help shed a different light on what was certainly not a flattering childhood. The way he describes it, in fact, makes everything that happened seem funny, for example, the dog and children hiding in fear in the upstairs bathroom while their father went off and destroyed everything in sight. Kleinzahler also claims that he was a mistake, that he was conceived while his mother was in a drunken frenzy, and that her mother had an insane rule over his mom and her sisters. These are all ingredients for a disastrous childhood, but through the eyes of August Kleinzahler, it all seems almost normal. He makes it hard not to laugh at such gruesome misfortune, the way he describes the various characters in his early childhood, especially the dog. As the author describes the importance of his dog, he also goes on to equally describe the many interesting and unique characters...

...Pains or Juvenile Delinquents Thinking back to the time of Classic Rock and Roll, Elvis, Buddy Holly, Dirty Dancing, and a faraway land called Viet Nam. Viet Nam affected families; fathers, brothers, children were dying and the age of the innocence was lost forever. Juveniles began a culture of their own, smoking, drinking alcohol, using drugs to attain a mental or in some cases a physical high to ease their pain of loss. This behavior began as a way of coping with their pain, when they realized this made them feel good, they wanted to continue this feeling. During the 1960’s it was a time of rebellion, with music, dancing, the hippie movement, free love, flower power, and the introduction to drugs to get high such as marijuana, glue sniffing, LSD and alcohol. Most of the youth at that time was into smoking cigarettes, drinking alcohol and some did smoke marijuana. This was the leap from child to adult behavior or some would call juvenile delinquency. Each time a beer touched the lips it was breaking the law and leading to more risky behaviors. By the time the junior year 1968-1969 rolled around, it was drinking most every night and stayed sober on game day or night until after the games. Then win or lose it was party time. There was very seldom a day that there was no one partying. After school and the weekends we were the party animals, smoking, drinking, and listening to our music, and then attend church on Sunday morning only if we had too. In the context of things...
