ABSTRACT

Water pollution poses great threat to human health. Because of this, natural filters are recommended for use. This study evaluated the potential of corn cobs as an alternative filter material in the removal of impurities in water by measuring the flow rate, pH level and the color of the filtered sample.
The corn cobs were grinded and activated using water and vinegar with the ratio of 1:3 and served as the alternative filter material. The activated carbon were placed in a transparent tube at varying thickness and served as treatments T1 (0.5 inch), T2 (0.75 inch), T3 (1 inch), and T4 (control).
Results showed that T1 has the fastest flow rate, T3 has the highest pH level and lightest color. Statistical analysis showed that there is a significant difference on the flow rate among the four samples. The pH level among T1, T2 and T4 are not significantly different with each other but significantly different with T3. These lead to conclusion that the flow rate increases as the thickness of the filter material decreases. On the other hand, the pH level and the lightness value increases as the thickness of the filter increases
Key words: corn cobs, activated carbon, filter, flow rate, pH level

...and profits, it will be seen, have a very intimate connexion with each other. The principles which regulate rent are briefly stated in the following pages, and differ in a very slight degree from those which have been so fully and so ably developed by Mr Malthus in his late excellent publication, to which I am very much indebted. The consideration of those principles, together with those which regulate the profit of stock, have convinced me of the policy of leaving the importation of corn unrestricted by law. From the general principle set forth in al Mr Malthus's publications, I am persuaded that he holds the same opinion as far as profit and wealth are concerned with the question; -- but, viewing, as he does, the danger as formidable of depending on foreign supply for a large portion of our food, he considers it wise, on the whole, to restrict importation. Not participating with him in those fears, and perhaps estimating the advantages of a cheap price of corn at a higher value, I have come to a different conclusion. Some of the objections urged in his last publication, -- "Grounds of an Opinion," &c. I have endeavoured to answer; they appear to me unconnected with the political danger he apprehends, and to be inconsistent with the general doctrines of the advantages of a free trade, which he has himself, by his writings, so ably contributed to establish. On the Influence, &c. Mr Malthus very correctly defines, "the rent of land to be......

Corn

...there looking all “sweet”, but I know deep down, you’re just about ready to POP! You know how I know? Because...you’re… corn. “What?” you say, “I’m not corn, I’m a person!” ah-ah-ah, you see, I am a firm believer that you are what you eat; and I’m fairly convinced that you, myself, and everyone else in America, eats corn. <Beat>+<Beat in between sentences> About three years ago I was watching an episode of the Colbert Report in which he pointed out our nation’s insane dependence on corn. It made me realize just how unaware of corn we actually are. A good analogy our situation with corn, is that of the Bourne Series, where a man wakes to find he does not remember anything of his past, and must fight through a corrupted government to find the Truth. Like Mr. Bourne, we have forgotten just what corn means to us, and the hold it has over us. But by examining how our society became rooted in corn, and why our society will never be able to shuck its corn dependence, you can skip the violence and go straight for the understanding. I’ll begin with explaining corn itself, or, The Corn Identity The history of corn is summarized nicely by, surprise surprise, Mike Gibson of Iowa State University: Corn, known as Maize in all but a handful English-speaking countries, is a grain originally domesticated by peoples in Mesoamerica around 2,500 B.C. Corn was the major crop for the Aztecs, Mayas, Incas and various Pueblo dwellers of the southwestern United States. Next,......

King Corn

...King Corn Corn is a plant that can grow in various types of climates, making it the top crop grown in the world. However, a certain type of climate is optimal for most efficient production of corn. Corn needs a temperate weather and good soil. These conditions, as well as the use of hybrid seeds, provide a basis for the huge corn industry in the United States. According to Conceicao and Mendoza, “About 90% of corn and soybean exports are accounted for by only three countries: Argentina, Brazil and the USA. Five countries (India, Pakistan, Thailand, USA and Vietnam) account for over 80% of global rice exports.” King Corn follows two best friends from college, Ian Cheney and Curt Ellis, who go to the heartland to figure out what their food is composed of after finding out in a laboratory study that their DNA was mostly made up of corn. They were curious how corn ended up on their hair. After they plant and grow an acre of America's most produced and most subsidized on Iowa soil, they try to find out where the corn goes in the food system and how it is distributed all over America. What they discover shocks them. There are many reasons why there is an overproduction of corn in the United States, including advancements in technology, government subsidies, the cheap price of corn and corn syrup as opposed to grass and sugar. Overproduction of corn leads to overconsumption of the crop, because since corn is so cheap to grow, many try to figure out new ways on how to......

Filter Bubble

...Brandon Voelker Team #5 Article 1: How to Burst the “Filter Bubble’’ that Protects Us from Opposing Views Date: November 29, 2013 The article on how to burst our ‘’Filter Bubble’’ is actually a very interesting phenomenon due to the fact it is actually full of very good information that is supported with testimonials. In 2011 Eli Pariser found that the way two people googled the same term received different answers was because of what they had beliefs in. Research has showed Pariser that people are more likely to use information or read information that they agree with. The use of social media and how they can filter things has developed a problem due to the fact now people only view the content that they want to hear or say. Eduardo Graells-Garrido, Mounia Lalmas, and Daniel Quercia at the Universitat Pompeu Fabra in Barcelona have used Yahoo to try to burst the filter bubble by trying to find things that people do agree on even if they do have opposing views on strong topics. By doing this they have gathered that people are shown many more ideas, people, and opinions than they would ever experience by keeping their filter bubbles. Why this is being so successful is due to the fact that people are still using their own interests to be exposed other opinions and interests. The case study that they found the most information and productivity was with the abortion case. They chose to do their study in Chile one of the most restrictive anti-abortion countries in the...

Corn and the Native Americans: a Brief Journey Through the Maize

...Corn and the Native Americans: A brief journey through the maize Humanities 215-V1 Native American Cultures Larry Jent April 12, 2012 Throughout the history of Native American culture corn has played a vital role in many facets of life for a multitude of people in various ways. It is not merely a simple grain or vegetable, it is a sacred gift to all people. Not only does it nourish one physically and provide for material use, but it is also an important spiritual tool. Corn plays a vital role in Native American culture. It is an agricultural mainstay, is integral to many ceremonies, honored in many celebrations throughout many tribes, and is credited with nourishing the nation physically as well as spiritually through various myths and legend. Food for Thought Corn was one of the first domesticated crops by the native people. “Over a seven-thousand-year period, Indian people domesticated hundreds of kinds of maize, beginning in the semiarid highlands of Mexico with a common wild grass called teosinte” (Ballantine 60). “The teosinte pollen, carried by the wind to other corn like grasses, produced a hybrid whose cultivation helped ensure a stable food supply” (Maxwell 44). With the ability to reproduce food in a single location it was easier for people to settle in certain areas. This provided for a more domesticated way of living and a steady source of nourishment. Corn could be used immediately,......

Cigarette Filter Glue

...Feasibility of Using Used Cigarette Filter as Glue Chapter I Introduction A. Background of the Study: This experiment aims to develop a product that would serve as an alternative for some expensive commercial glue. There are many people-using cigarette and after using they just toss aside a cigarette while walking not thinking that it can be recycle and used. Commercial glue is relatively expensive because the materials used in manufacturing are tissues from animals. B. Problem: This study aims to test the feasibility of using cigarette filter as a source of glue. C. Hypothesis: Alternative- hypothesis: Cigarette filter is a good source in producing glue. Null- Hypothesis: Cigarette filter is not a good source in producing glue. D. Significance: Glue is very common used in homes, schools and offices. Many people just toss aside a cigarette filter and it can be recycled and used. Due to the expensiveness and unaffordable of some glue, many would prefer making home made glue. Glues from cigarette filter is affordable and easy to make. E. Scope and Limitation: This study only limited by their stickiness. There are many kinds of glues, they are stick glues, paper glues, glitter glues and etc. This glue differ according to its quality. This glue that we made can’t be used as stick glue because the glue that we made is liquid. This study is limited only for paper, cloth and wood. F. Definition of Terms: Cigarette filter- is a foam-like found at the end......

Corn

...Corn America The demand for corn has greatly increased because of its many new found uses but mainly because it has been discovered that corn can be use as an alternate energy source. This great demand for corn has increased many area of farming and production of corn here and other countries such as Mexico and South America. This great demand has lead to an increase in farmers who are willing to cash in on these cash crops and try to earn a few quick dollars because of the great demand for it. In 2007 Corn farmer saw record profits because famer where getting twice as much for corn as they did in previous years. The same trend continued but farmers dealt with so many obstacle such as weather, bugs and lack of equipment that they found themselves in an upside down situations. (www.cnn.com) Many of the corn farmers have made lots of sacrifices to meet the demands of corn by producing more corn, buying more land and seeds, use of extra fuel in farm equipment, which increased the farmers spending but also return great profits. This will cause the production of corn’s substitute, soybean, to diminish but not disappear because soybeans have a market of their own in china because of its production of soybean oil and milk that is wide spread in China.  As far as the US and soybean its production will slowly starts to diminish because many of the farmers will use their land to grown more corn to gain a better profit, instead of growing soybean and......

Perceptual Filters

...4/25/16 PL101 Taking Control of Perception Filters Throughout life, people go through their day to day schedules seeing and perceiving just about every experience in a “certain light.” A light in which shade is brighter, darker or just “blah” depending on that person’s overall self-awareness, mood or attitude. An individual’s mood or “filter,” as I like to call it, acts as a pair of glasses that can literally transform all of your surroundings and how you experience them. Your mood and emotions (for the most part) determine the “type” of glasses you are perceiving your reality through. If an individual is angry, their “angry glasses” will be slipped on, seemingly subconsciously, and the “energy” around them immediately loses its value and becomes diminished in a sense. Think about it, have you ever woken up, and as you were getting out of bed you stubbed your toe, and the rest of your day seemed to be more aggravating than usual? Maybe your commute to work seemed slower and more agonizing, or when you finally got to work your boss asked you to pick up an extra task because someone else didn’t show up that day. In other words, everything seemed more tedious to the point where you are just “not in the mood.” It is not that, all of the sudden, on that specific day the world changed its perception and attitude towards you, but because you changed your perception and attitude towards the world. The most dangerous part about these perception filters is that it is very hard to......

Corn Threshing Machine Dust Mixing and Material Quality Testing

...CORN THRESHING MACHINE dust mixing and material quality testing: In the corn processing, there always has some sand and dust mixed in the corn threshing machine. How should we do to avoid dust mixed in the corn threshing machine? First, do a good job for corn cleaning to avoid too high sand content. Second, keep frequent cleaning to the corn threshing machine. Avoid the residual dust in the corn threshing machine which may cause some pollution to the corn products. Third, check the corn threshing machine airtightness. It can reduce dust invasion by improving corn threshing machine airtightness effect. Corn threshing machine can process corm into various products, such as corn kernels, corn grits, corn flour, corn germ and so on. Each corn product needs purity and quality. If there has too much sand or dust mixed in the corn threshing machine, then these end products will be affected. For example, corn grits and corn flour will have coarse taste due to the sand or dust mixing. This will also reduce the end products economic profits and our trust on the corn threshing machine. Therefore, that’s why many corn threshing machine manufacturers ask us to pay more attention to the corn cleaning first before corn threshing machine working. The corn products processed by corn threshing machine always have some quality standard, and the raw corn material which can meet the standard needs always can be processed into much higher quality corn products so as to improve......

In the deep processing of grain and expanding people's rising income levels today, finishing rice, flour, processed mostly vitamins and other substances the body must be away, leaving the sugar, carbohydrates, etc. That can not meet the body's nutritional needs. Corn innovation becomes very necessary. However, for most people prefer to add up the corn, for both add corn kernels, add the corn residue or crushed, or cornmeal, all feel when eating mouth running, bitter taste, bad taste. Artificial rice corn in this case came into being. Artificial fine cornmeal corn rice is peeled to the navel as raw material, through the water and stir puffed shaped, pale yellow translucent gel particles, shape much like rice. Made of artificial rice cooked rice with corn, two meters cooked rice, porridge, smooth and delicious, taste good.
