What Is A Polymer?

What Is A Polymer?

by

Rolf Keegan

A polymer is a term commonly applied to man-made plastics and composites. In actuality, this is a misconception as polymers are not limited to man-made materials, and are also naturally occurring. A polymer is a synthetic or natural chemical compound which is constructed of molecules that are bonded together in long repeating chains. The main benefit of using polymers is that they can be easily tailored to a variety of purposes due to their unique malleable properties.

What are polymers composed of?

Polymers encompass a wide range of natural and synthetic compounds, with a wide range of properties. All polymers are created through a mixture of compounds which are link together creating in repeating substructures. This creates a long repeating chain of molecules.

What are natural polymers?

Common examples of natural polymers include materials such as wool, silk and rubber. Natural polymers are produced by living organisms such as the silk worm. They are materials which are made up of raw natural materials such as protein, carbohydrates and lipids. Hair and nails are in actuality natural polymers, as are shells.

What are man-made/synthetic polymers?

Man-made or synthetic polymers are constructed from chemical human-made materials. Synthetic polymers are most commonly classified into four main categories: thermosets, thermoplastics, elastomers and synthetic fibers. With synthetic polymers the molecule construction is the same as for natural polymers; it is only the material composition that differs. Synthetic polymers cover a wide range of materials and uses, such as fabrics (nylon, elastic and viscose), house-hold appliances such as Teflon non-stick pans, and a vast array of plastics and rubbers. One very important difference between synthetic polymers and natural polymers is that synthetic polymers are most often non-biodegradable. Although today, many can be recycled reducing the negative environmental impact upon the earth.

What are the benefits of polymers?

Polymers are extremely useful and can be tailored for almost any purpose. The process of polymerization is extremely complex and unique. Polymers are durable and can be formed into a variety of shapes and used for a variety of purposes. Most polymers are also safe and non-toxic making them excellent materials for using in cookware, storage containers and for children\’s toys.

What are the negative of polymers?

The negative aspect of polymers mainly lies within the process of creating synthetic polymers. Synthetic polymers are manufactured from hydrocarbons derived from crude oil. The process of creating synthetic polymers has a negative effect on the environment as consumes a large portion of dwindling supplies of crude oil. They are also normally non-biodegradable, creating a negative impact on the environment. According to scientists it is estimated that a single plastic bag could take as much as 500 years to fully break down, and when you consider how many are thrown away on a daily basis, it creates a shocking image. Synthetic polymer materials are used in many disposable products, meaning they end up discarded and being sent to landfills. However, there is now thankfully a greater awareness about the negative impact synthetic polymers is having upon the environment, and more and more people are taking care to recycling their synthetic polymer waste.

Author Amy Scobee recounts abuse as Scientology executive

Monday, October 11, 2010

Wikinews interviewed author Amy Scobee about her book Scientology – Abuse at the Top, and asked her about her experiences working as an executive within the organization. Scobee joined the organization at age 14, and worked at Scientology’s international management headquarters for several years before leaving in 2005. She served as a Scientology executive in multiple high-ranking positions, working out of the international headquarters of Scientology known as “Gold Base”, located in Gilman Hot Springs near Hemet, California.

Wikinews interviews Rocky De La Fuente, U.S. Democratic Party presidential candidate

Thursday, March 31, 2016

Businessman Rocky De La Fuente took some time to speak with Wikinews about his campaign for the U.S. Democratic Party’s 2016 presidential nomination.

The 61-year-old De La Fuente resides in San Diego, California, grew up in Tijuana, and owns multiple businesses and properties throughout the world. Since getting his start in the automobile industry, De La Fuente has branched out into the banking and real estate markets. Despite not having held or sought political office previously, he has been involved in politics, serving as the first-ever Hispanic superdelegate to the 1992 Democratic National Convention.

De La Fuente entered the 2016 presidential race last October largely due to his dissatisfaction with Republican front-runner Donald Trump. He argues he is a more accomplished businessman than Trump, and attacks Trump as “a clown,” “a joke,” “dangerous,” and “in the same category as Hitler.” Nevertheless, De La Fuente’s business background begets comparisons with Trump. The Alaskan Midnight Sun blog described him as the Democrats’ “own Donald Trump.”

While receiving only minimal media coverage, he has campaigned actively, and according to the latest Federal Election Commission filing, loaned almost US$ 4 million of his own money to the campaign. He has qualified for 48 primary and caucus ballots, but has not yet obtained any delegates to the 2016 Democratic National Convention. Thus far, according to the count at The Green Papers, De La Fuente has received 35,406 votes, or 0.23% of the total votes cast. He leads among the many lesser-known candidates but trails both Senator Bernie Sanders who has received nearly 6.5 million votes and front-runner Hillary Clinton who has just shy of 9 million votes.

With Wikinews reporter William S. Saturn?, De La Fuente discusses his personal background, his positions on political issues, his current campaign for president, and his political future.

Timber Frame Homes

Timber Frame Homes

by

Robert Davidson

You know deep down inside that you want a Timber Frame Home, but you’re not exactly sure where to start. First, you need to find a designer, but now the question becomes, do you use a stock floor plan that’s provided by your selected Timber Frame Home Construction company or do you use their custom design services and make it truly one of a kind, change the layout and make it your own?

[youtube]http://www.youtube.com/watch?v=Z9FzzFyuxuA[/youtube]

Building a custom timber frame home is all about incorporating architectural details that will create a comfortable design that suits your lifestyle. So when you sit down to plan your perfect dream home take a few moments to consider what kind of spaces you’ll need to fit your needs. Here are a few ideas that can really make your timber frame home special. If you have enough space and money you may want to add a wine cellar. Even if your not a connoisseur, a wine cellar is a great conversation piece when hosting a get together. If your wine room was big enough you could even hold a small intimate wine tasting event for your friends. Just remember even if your turning an extra closet into a wine room, the key is temperature control. Invest in a air conditioner that is made for wine cellars, a normal home air conditioning unit cannot maintain the constant 55 degree temperature needed for storing your wine, without icing over. Maybe your a music lover or a movie buff. Why not let the kids come in from the garage and practice in a specially designed music room. Or maybe you want to have the gang over for a movie night in your new home theater room. Whichever way you go, acoustics are going to be a big priority. Check with your local acoustic consultant to see what your options are, maybe you will need a cork floor to help improve the sound quality. Using wall coverings like foam panels will help to sound proof the area. Your plans should always include extra outlets, you may need them to plug in equipment like amps, recording gear, TV’s, Computers and any other electrical device you may need. How about a hobby room? Rather than ruining your kitchen table or making a mess in the living room, why not plan to build a hobby room? A hobby room can go anywhere, spare room, the basement, or even the garage. If you plan on using the hobby room for a while built in storage is a good option. There are so many things you can do, a sewing room, scrap-booking room, crafts, RC airplanes and cars or even fly tying. There are so many ways that you can make your Timber Frame Home unique. Let your imagination be your designer, that and your pocketbook, but take the time and make it your own because the memories will last a lifetime.

Report reveals Top 10 most-confusing tech buzzwords

Sunday, March 27, 2005

Danville, California — The California-based Engligh language tracker, Global Language Monitor, released its 2005 list of most confusing – yet frequently cited – high tech buzzwords to be “HTTP,” “Voice Over IP” (VoIP), and “Megapixel.” Closely following were “Plasma,” “Robust,” “WORM” and “Emoticon.”

In early March, the group used a predictive index computer algorithm to track specific words and phrases in the media and on the Internet. They were tracked in relation to frequency, contextual usage and appearance in global media outlets.

The Global Language Monitor claims to analyze and catalogue trends in word usage and word choices, focusing on the linguistic impact on various cultures. The GLM says it relies upon a global network of volunteer linguists, professional wordsmiths and other bibliophiles to monitor the trends in the evolution and demise of world languages.

GLM’s list, in order of frequency of use, of the most-confusing technology terms with the group’s explanation as to why they are faulty follows:

  1. HTTP – HyperText Transfer Protocol is the standard protocol used for transmitting web pages (which are written in HTML (HyperText Markup Language)), not text written while hyper on too much Starbucks coffee. There are more than 1 billion references to HTTP on the web alone.
  2. Voice over IP – Voice over Internet Protocol, (pronounced voyp, similar to Detroit) is a way of transmitting voice data over the Internet. VoIP is becoming more popular as services such as Skype offer people free voice communication with anyone with a broad-band connection.
  3. Megapixel – Approximately one million pixels, not a single, big pixel (“mega” is the metric system prefix for million). “Pixel” itself is a technical term which means “picture element”. Digital pictures consist of a grid of millions of pixels, which are square or rectangular dots, each having a single colour.
  4. Plasma – A plasma display (commonly used in televisions) is a flat, lightweight surface with a grid of millions of tiny glass bubbles containing plasma. A digitally controlled electric current flows through the bubbles causing the plasma inside to glow various colours. Plasma displays have nothing to do with blood plasma.
  5. Robust – Robustness generally means “it won’t break easily.” It supposedly describes computer programs or hardware that have been well-tested and demonstrated to not crash or fail often, but since it is a vague term by nature (how robust is robust?) it is frequently used by marketing types regardless.
  6. WORM – While a worm is a type of computer virus, WORM stands for ’Write Once, Read Many’. It describes a file system primarily used for optical disks, such as CDs and DVDs. For example, CD-Rs can only be written (or “burned”) once but afterwards can be read many times (otherwise you could only listen to your music CD once). This excludes re-writable CDs which can be written many times.
  7. Emoticon – Emoticon stands for emotional icon. An emoticon is a sequence of characters that look visually like a face and are used in text chat to convey emotion. The most common emoticon is the smiley face – 🙂 – which looks like two eyes and a mouth turned 90 degrees.
  8. Best of Breed – Not to be confused with the Westminster Dog Show, a best-of-breed product is a personalized solution made of components from various manufacturers; in other words, it’s a sort of high tech ‘mix-and-match’.
  9. Viral Marketing – A recent marketing trend which relies on word-of-mouth to spread, rather than traditional advertising strategies. It is called “viral” because as people talk about it, the marketing message “spreads” to new people, who in turn inform others, and so on, which is how viruses spread. The Burger King “Subservient Chicken” campaign is considered an example of viral marketing. Computer viruses used by spammers to turn desktop computers into “zombie” spam relays are something completely different.
  10. Data Migration – Data migration is an idealistic (though usually impossible) concept where data can be used by different versions of the program in which it was created (newer or older). The migration (migration means “to move”) refers to the fact that the data is moved from one version (or program) to another without difficulty or loss of information. It is a subset of backward and forward compatibility.

Other terms being tracked included “client/server,” “solution,” “paradigm,” “backward compatible,” and the “STUN protocol.”

Edmund White on writing, incest, life and Larry Kramer

Thursday, November 8, 2007

What you are about to read is an American life as lived by renowned author Edmund White. His life has been a crossroads, the fulcrum of high-brow Classicism and low-brow Brett Easton Ellisism. It is not for the faint. He has been the toast of the literary elite in New York, London and Paris, befriending artistic luminaries such as Salman Rushdie and Sir Ian McKellen while writing about a family where he was jealous his sister was having sex with his father as he fought off his mother’s amorous pursuit.

The fact is, Edmund White exists. His life exists. To the casual reader, they may find it disquieting that someone like his father existed in 1950’s America and that White’s work is the progeny of his intimate effort to understand his own experience.

Wikinews reporter David Shankbone understood that an interview with Edmund White, who is professor of creative writing at Princeton University, who wrote the seminal biography of Jean Genet, and who no longer can keep track of how many sex partners he has encountered, meant nothing would be off limits. Nothing was. Late in the interview they were joined by his partner Michael Caroll, who discussed White’s enduring feud with influential writer and activist Larry Kramer.

Top 10 Anti Aging Foods For The Skin

By Susan T.G William

Aging and food are related. Do you know that foods play an important role in helping to fight the signs of aging. Different types of foods have different nutrients that can help us to sustain youth. Therefore it is very important to watch what you eat to ensure that you eat foods that can help you look young and feel young. You can feel the difference by looking at your skin, whether it is smooth or with wrinkles. So eating the right food can help you halt the signs of aging thus making you look younger for a longer time.

There are many categories of foods. Surprisingly, there is a category of foods known as superfoods. How do we define superfoods? Superfoods are foods that contain high amount of Essential Fatty Acids, antioxidants and fiber. However, superfoods may contain one or more of the nutrients. Studies shown that there are particular superfoods can reduce levels of cholesterol, lower the risk of heart diseases and ensure organs are functioning properly. The EFAs, antioxidants and fiber are able to provide sufficient nutrients for the body so that cells are able to repair itself and keep the digestive system healthy apart from erasing wrinkles.

Scientists have narrowed down the superfoods to the top ten superfoods that are proven to be fully beneficial. They are green foods, barley, acai, allium family, beans or lentils, sprouts, hot peppers, buckwheat, yogurt or kefir and nuts or seeds. These are the top superfoods that have high level of EFAs, antioxidants and fiber that are scinetifically proven against all other types of foods in the laboratories.

[youtube]http://www.youtube.com/watch?v=Pvz5w7Dofaw[/youtube]

Green foods have the power to lower the risk of getting cancers, lower the cholesterol levels and reduce the high blood pressure. Barley is the best source for fiber and it is useful in helping to regulate the level of blood sugar. Acai is full of antioxidants and EFAs. The allium family include garlic, onions, chives, shallots and leeks that have very powerful antioxidants for better liver functions. Beans and lentils are rich in antioxidants and have low GI. Sprouts are rich in protein and vitamin C.

Hot peppers on the other hand are full of antioxidants and also capsaicinoids that is anti-cancer compund. Buckwheat is not truely grain but it is healthier than rice, corn and wheat. Yogurt or kefir have live cultures that promote good health. Last but not least the nuts and seeds have EFAs to ensure healthy skin and is one the great superfoods. These are extremely powerful superfoods, otherwise they would not be in this group of superfoods.

The good thing about these superfoods is that they are not expensive and not difficult to find in local stores and supermarkets, thus you have easy access to all these foods. The price is affordable and it is all natural. To look good and feel young, you don’t have to waste tons of money buying beauty products that are chemically produced. So, you don’t have to consume poison to sustain youth but with natural foods you can achieve the same results and perhaps even better than dietary supplements.

So there you have it, the list of the top ten superfoods you should be eating more in your daily meals while cutting down on the others so that you will look and feel younger, live a healthy life, have firmer skin, no wrinkles and definitely, no signs of aging at all. Best of all it is a natural way.

SpaceX scrubs Falcon I rocket launch

Monday, November 28, 2005

SpaceX called off the much-delayed inaugural launch of their new Falcon 1 rocket on Saturday from Kwajalein’s Omelek Island launch site. The intent was to launch the U.S. Air Force Academy’s FalconSat 2 satellite, which will monitor plasma interactions with the Earth’s upper atmosphere and magnetosphere.

The launch was delayed, then finally cancelled after an oxygen boil-off vent had accidentally been left open. The oxygen was unable to cool the helium pressurant, which then proceeded to evaporate faster than it could be replenished. A main computer issue, probably serious enough to cause a scrub on its own, was also discovered.

This long-anticipated flight was originally expected to be launched in January 2005, however a series of setbacks forced a series of delays, with the flight most recently scheduled to be in early 2006. It was intended to be launched from the Kwajalein atoll in the middle of the Pacific Ocean.

The maiden voyage was originally intended to launch from Vandenberg Air Force Base in California with a Naval Research Laboratory satellite and a Space Services Incorporated space burial payload.

At least 53 killed, over 90 injured in Shanghai apartment fire

Tuesday, November 16, 2010

China’s Xinhua News Agency said Tuesday that at least 53 people were killed in Shanghai during a deadly fire. The blaze, which occurred on Monday at 2:15 p.m. CST (0615 UTC), consumed a 28-story high-rise apartment building in the city’s Jing’an District.

The building was being renovated at the time of the fire, and was home to over 150 families. At least 100 victims have been admitted to area hospitals, although some later died. Most survivors were not seriously injured, but needed treatment for smoke inhalation. Firefighters were still looking for survivors and over 70 were still hospitalized on the morning after the fire.

The fire was the worst in recent Shanghai history and took over 100 fire engines more than four hours to contain. Strong winds blew heavy smoke into the air, hampering rescue efforts by helicopters. The smoke was seen by witnesses around 15 kilometres (9.3 miles) away from the high-rise. The fire was largely extinguished by 6:30 p.m. local time (1000 UTC), allowing fire and rescue officials to enter the building.

The apartment building, built in the late 1990s, was home to mainly retired teachers. Some residents climbed down the scaffolding to escape, while others called for help but were unable to flee the blaze. “I saw at least four or five people hanging onto the scaffolding which covers the building, screaming for help,” said Li Qubo, who was working near the high-rise.

The cause of the fire has not yet been determined, but local residents said fire safety regulations were not strict, and workers often tossed used cigarettes into the building’s hallways. Qiu Jingshu, a 38-year-old worker who was outside the 18th floor when the fire struck, said he saw sparks from welding being done on an adjacent building fly over onto the high-rise. The sparks lit up foam on the scaffolding around the apartment, according to Qiu. “We had tried to put out the blaze, but the fire was so big and spread so quickly that we could barely escape ourselves,” he said. Crews were said to have been installing insulation at the time of the fire, and witnesses saw construction materials on fire before the building was overtaken by flames.

Two nearby buildings were evacuated, and their residents were temporarily sent to local hotels, and a school. Meng Jianzhu, China’s Minister of Public Security, said that an investigation would determine who was responsible for the fire, so they could be punished accordingly. Meng said that a team had been formed under China’s State Council to look into the disaster.

A similar incident occurred in Beijing early last year. In February 2009, the illegal use of fireworks caused a fire that gutted a 34-story building under construction at the time.

Shanghai has a population of about 20 million, housed mainly in high-rise apartments. Many buildings in the city are under construction or being renovated.
