As such, the chances of having information that is correctly vetted for the truth in the matter is highly likely. This can be accessed by clicking the “View history” tab at the top of the article and selecting the latest revision: Coated paper has a thin layer of material such as calcium carbonate or china clay applied to one or both sides in order to create a surface more suitable for high-resolution halftone screens. This fast-paced and hilarious trivia game has over 400 questions about things that you should know. Wood is ground up and mixed with water and other chemicals to make a thin liquid called "paper pulp". They are known to be carcinogenic. The pulp can also be bleached to produce white paper, but this consumes 5% of the fibres. Printing is often done on paper before the paper is cut into sheets. ), Stockholm Convention on Persistent Organic Pollutants, "ARCHIVED – Introduction – Detecting the Truth. It has such a broad subject matter available and it can connect you to further research on the subject. [4] Because paper was introduced to the West through the city of Baghdad, it was first called bagdatikos. The usage of paper currency later spread throughout the Mongol Empire or Yuan dynasty China. These sources can be useful for your own research and can also inform you of the reliability of the article on Wikipedia. Although Wikipedia is a good place to start your research, it is not a credible source that you should use to cite from. It is a versatile material with many uses, including printing, packaging, decorating, writing, cleaning, filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, currency and security paper and a number of industrial and construction processes. When making paper by hand, a blotter sheet is used instead. With almost twice the yield as chemical pulping, mechanical pulps is often cheaper. "Printing, Paper and Playing Cards". Paper is often characterized by weight. A1 is half the size of a sheet of A0 (i.e., 594 mm × 841 mm), such that two sheets of A1 placed side by side are equal to one sheet of A0. The ISO 216 system used in most other countries is based on the surface area of a sheet of paper, not on a sheet's width and length. The Modern Language Association style has its own guidelines for citing Wikipedia as a source. Another advantage is that this process recovers and reuses all inorganic chemical reagents. Along with bamboo, hemp is one of the fastest growing plants on Earth. Dioxins are highly toxic, and health effects on humans include reproductive, developmental, immune and hormonal problems. Wikipedia is not the only user-created encyclopedia. Before the industrialisation of paper production the most common fibre source was recycled fibres from used textiles, called rags. Frequently Asked Questions about Wikipedia as a credible source. Follow with a period. Below are dozens of Wikipedia alternatives you can use to find information, research a paper, get quick answers, and much more. [25] The cellulose fibres that make up paper are hydrolyzed by acid, and the presence of alum eventually degrades the fibres until the paper disintegrates in a process known as "slow fire". They run perpendicular to the "chainlines", which are further apart. The pulp is fed to a paper machine, where it is formed as a paper web and the water is removed from it by pressing and drying. Preconsumer waste â€“ This is offcut and processing waste, such as guillotine trims and envelope blank waste; it is generated outside the paper mill and could potentially go to landfill, and is a genuine recycled fibre source; it includes de-inked preconsumer waste (recycled material that has been printed but did not reach its intended end use, such as waste from printers and unsold publications). Paper made from mechanical pulp contains significant amounts of lignin, a major component in wood. Also, even if you paraphrase, always cite the source at the end go your sentence in parenthesis. [30] The average office worker in the US prints 31 pages every day. For example, see the below sources from the Wikipedia article on Thermodynamics (Wikipedia, 2019d). Always put quotation marks around any thre word progression in your paper that is a direct quote from the source. It was not until the introduction of wood pulp in 1843 that paper production was not dependent on recycled materials from ragpickers. Also, even if you paraphrase, always cite the source at the end go your sentence in parenthesis. Mechanical pulps have rather short fibres, thus producing weak paper. The kraft process, invented in the 1870s and first used in the 1890s, is now the most commonly practised strategy; one of its advantages is the chemical reaction with lignin produces heat, which can be used to run a generator. Documents written on rag paper are significantly more stable. Postconsumer waste â€“ This is fibre from paper that has been used for its intended end use and includes office waste, magazine papers and newsprint. Stationery Stores, Wedding Invitations, Gifts & More | Paper Source Write the article title, followed by a period. Captions. (Uncoated papers are rarely suitable for screens above 150 lpi.) All paper produced by paper machines as the Fourdrinier Machine are wove paper, i.e. Here's how you can use Wikipedia for your research: Wikipedia can be great for your first research on a topic. The hardest part in research can sometimes be finding the right keywords to use when searching libraries or databases. Paper at this point is uncoated. [8][9] Papyrus is a thick, paper-like material produced from the pith of the Cyperus papyrus plant, which was used in ancient Egypt and other Mediterranean cultures for writing before the introduction of paper. Make sure to always check the references section at the bottom of the article. Paper recycling processes can use either chemically or mechanically produced pulp; by mixing it with water and applying mechanical action the hydrogen bonds in the paper can be broken and fibres separated again. Don’t quote or paraphrase from the Wikipedia entry in your paper, but check the entry’s Reference section to find links to more authoritative sources. Wikipedia is increasingly used by people in the academic community, from first-year students to professors, as the easiest source of information about anything and everything. Most recycled paper contains a proportion of virgin fibre for the sake of quality; generally speaking, de-inked pulp is of the same quality or lower than the collected paper it was made from. Write “Wikipedia” with… [33], The paper pulp and print industries emitted together about 1% of world Greenhouse-gas emissions in 2010[34] and about 0.9% in 2012,[35] but less than screens: digital technologies emitted approximately 4% of world Greenhouse-gas emissions in the year 2019 and the number can be two times larger by the year 2025. Wikipedia:Wikipedia as a conference paper source. This means that the element of vetting the right persons to edit the content on the website is not available. There are two major mechanical pulps: thermomechanical pulp (TMP) and groundwood pulp (GW). Wikipedia entries are generally in the forefront of any web research and can be great sources to get preliminary information on a topic and find reliable sources through their notes, references, external links and further reading sections. Logging of old growth forests accounts for less than 10% of wood pulp,[29] but is one of the most controversial issues. Also, synthetics such as Tyvek and Teslin have been introduced as printing media as a more durable material than paper. Gloss papers give the highest optical density in the printed image. Real Estate Note Brokering and Investing Education. As the vast majority of this material has been printed â€“ either digitally or by more conventional means such as lithography or rotogravure â€“ it will either be recycled as printed paper or go through a de-inking process first. The first papermaking process was documented in China during the Eastern Han period (25–220 CE) traditionally attributed to the court official Cai Lun. The rags were from hemp, linen and cotton. Wikipedia reports information from other sources, making it a secondary source. Paper is a thin sheet material produced by mechanically and/or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Wikipedia allows multiple users to edit, and it is not safe to assume that the facts presented there have been checked before publishing them. Paper waste accounts for up to 40% of total waste produced in the United States each year, which adds up to 71.6 million tons of paper waste per year in the United States alone. And, because many Wikipedia entries contain thorough citations, they can be good starting points to find the original source materials you do want to use. Mass-market paperback books and newspapers tend to use mechanical papers. These can be sites with further information and often, they are credible sources that can be used to cite from. The density of paper ranges from 250 kg/m3 (16 lb/cu ft) for tissue paper to 1500 kg/m3 (94 lb/cu ft) for some specialty paper. The thickness of paper is often measured by caliper, which is typically given in thousandths of an inch in the United States and in micrometres (µm) in the rest of the world. Above all, make sure your teacher or professor will accept Wikipedia as a source, many of them will not. Chemical pulping processes are not used to make paper made from cotton, which is already 90% cellulose. We use extractive summarization to coarsely identify salient information and a neural abstractive model to generate the article.
