Lets Build a Snowman [CRITICAL UPDATE!]
Letâs Build a Snowman [CRITICAL UPDATE!] UPDATE: After a tip from Pro-snowman league warning us of a possible attack on our epic snowman by the anti-snowman league, we started receiving reports that the snowmans head had indeed been removed and destroyed in a vicious attack. Not to be deterred or beaten down, a recovery mission was dispatched to the snowman to assess the damage and administer any treatments necessary. Upon arrival at the snowman we deemed the head not fixable. We gave it a ceremonial sending off in the moat and sought a replacement. A traffic cone was deemed suitable. A message, addressed to the Anti-Snowman League, was attached to the traffic cone. Let it be known, to whomever maliciously assaults snowmen, we will never back down and we will fight for the survival of snowmen everywhere! We will defend! If I could give them out, Id give out an instant admit coupon to anybody who immediately recognizes the title reference. Anyway, I dont know if youve heard, but snow has officially dumped on MIT, creating about a foot of snow all over everywhere (except for the sidewalks, thank you facilities). Students here have shifted their footwear to boots, started doubling their pants and shirts, and were starting to see winter hats. I, for one, have ordered the awesomest hat ever, it should be here in about a week or two. We actually ordered 4 of these, expect epic rock band pics to come Along with the new wardrobes come new and exciting activities for MIT students to take part in. This includes snowmen. BUT!!! Were engineers, we dont just build lame snowmen, we build EPIC snowmen! Well, at least thats what the Facebook album describes it as, the epic snowman of IAP. It was originally James 11s idea, but Sauza 11, Wes 10, and I latched on to help. Step 1: Build giant bottom ball for the snowman. We did it the typical, fundamental way, roll a ball around in the snow until its really big. The thing is, really big snowballs are REALLY heavy, and at the end of it we were basically dying. We all leaned against the snowball, panting heavily, and then flung ourselves at it again, adding more and more snow. Kevin 11 snapped a picture of this process, this is when we started to realize how big the snowman was actually going to be. We packed some snow on it, rounded it off, and were left with a perfectly massive snowball. Step 2: Build the second ball for the snowman. This was easy, just a smaller snowball than the first. The tricky part was step 3. Step 3: Get the second snowball up onto the first snowball. But. . . how? The second snowball was impossibly heavy. We ended up having to build a large ramp out of two more huge snowballs, eventually heaving the second snowball up the precarious slope. The ramp itself was almost as impressive as the bottom snowball,and probably bigger in size. Step 4: Attach head. This was easy. Roll a snowball, carry it up the ramp, set it on top. Step 5: Features! We ran back to the dorm to get some more people and to get stuff for facial features. We grabbed a potato, cut in half, for the eyes, a carrot for the nose, a red bell pepper slice for the mouth, and three Solo cups for the buttons. We used a pirate hat for the hat, two wooden stakes for arms, and two lost gloves for hands (one pink mitten, one black leather glove). Again, the snow ramp was utilized, and the features were stuck nicely on the snowman. Step 6: Revel in the awesome! We grabbed a tape measure while we picked up the facial features, and the snowman came in at a staggering 10 feet tall (1 foot taller than Meliss snowman from last year). Step 7: Destroy evidence of the ramp. Giant snowmen only look amazing if you cant tell how theyre made. We took to destroying the snow ramp. Now for the group shots. Heres one of us expressing our affection for it. And our were hardcore pose And our pretend youre the snowman! pose Most of the snowmans features fell off today, I think all he has left are eyes and a Solo cup button. The body of the snowman, however, is probably going to be around until the end of winter (CPW if youre lucky) so well all get to enjoy him for quite a while. So that was my yesterday, building a giant snowman, just another day in the life.

Descartes Meditations On First Philosophy - 1080 Words
Throughout Rene Descartesââ¬â¢ Meditations on First Philosophy, God is not mentioned until the third meditation. Descartes point of view on God simply claims his existence through the act of being. According to his claim, God must, essentially, exist as well as being an outcome of His own creation. Descartes was greatly interested in the idea that Godââ¬â¢s being promoted an external force that controlled all beings that supported his presence. Descartes declarations, presented in his Meditations on First Philosophy, were based on the principle of a being who found the primary purpose of existing through naturally being a part of this world. With the sense of curiosity, Meditation III portrayed a detailed form that showed Descartesââ¬â¢ writingsâ⬠¦show more contentâ⬠¦Descartes was aiming to influence the Sorbonne schoolmen in order to find support in his writings but the odds could easily go against the ambitioned philosopher. The issue with a broad meaning is the challenge in finding a definite suggestion within the concept. However, such achievement cannot be done with any two views that possess unlike interpretations. Furthermore, in Descartes words, ââ¬Å"â⬠¦I shall efface even from my thoughts all the images of corporeal things, or at least (for that is hardly possible) I shall esteem them as vain and falseâ⬠(Wee 8), he believed that finding the core of his thoughts would be easily approached through the method of clearing all skeptical insights. His research begun by reassuring that he would find his true self ââ¬Å"â⬠¦and thus holding converse only with myself and considering my own nature, I shall try little by little to reach a better knowledge of and a more familiar acquaintanceship with myself (Wee 8), in order to support the existence of Godââ¬â¢s being. Descartes gives a naturalistic idea of Godââ¬â¢s being with the help of philosophical reasoning in order to give more support on the idea. When discussing alternate limitations on a philosophical point, it is sensible to use the basis of Descartesââ¬â¢ principles to clearly and thoroughly convey the message of ph ilosophical reasoning. Moreover, it can be argued that

Human Sex Trafficking - 1919 Words
An ounce of cocaine wholesale: $1,200. But you can only sell it once. A woman or child: $50 to $1,000. But you can sell them each day, every day, over and over again. The markup is immeasurable. This quote from the 2005 Lifetime film Human Trafficking, however chilling and horrifying, is true. Human trafficking is the commercial trade of human beings who are subjected to involuntary acts such as begging, sexual exploitation, or involuntary servitude. Human trafficking is an umbrella term used to describe all forms of modern-day slavery. No longer is this a term from the past, but a horrific reality in our present and, unfortunately, our future.

Some pimps even allow johns to murder the women and girls for an additional temporary sexual rush. The Lifetime movie, Human Trafficking, give many disturbing but accurate examples as to how people are lured into forced labor. Throughout the film, there are stories of five girls forced into prostitution. First is Helena from Czechoslovakia. Helena is brought to Vienna by a handsome stranger who says he wants to marry her, and then sells her to traffickers. Second is Nadia from the Ukraine. A modeling agency recruits her and brings her to the U.S. where they turn against her and force her into prostitution. Third is Annie from the U.S. While vacationing in the Philippines with her parents, Annie is lured away from her parents and kidnapped. Finally is Jasmine from the Philippines. She is a member of a very poor family and sold to a trafficker by her father. Although these examples are derived from a film, they are excellent examples as to the many ways young women are coerced into forced labor. Recruiting victims is effective when the potential victims family members are inv olved (Bales 44). The traffickers convince the girls to stay and keep their mouths shut by threatening to do serious harm to the victims loved ones.

Japanese Colonialism In Korea (725 words) Essay Example For Students
Japanese Colonialism In Korea (725 words) Essay Japanese Colonialism in Korea North and South Korea are nations that while filled with contempt for Japan have used the foundations that Japan laid during the colonial period to further industrialization. Japans colonization of Korea is critical in understanding what enabled Korea to industrialize in the period since 1961. Japans program of colonial industrialization is unique in the world. Japan was the only colonizer to locate various heavyindustry is in its colonies. By 1945 the industrial plants in Korea accounted for about a quarter of Japans industrial base. Japans colonization of Korea was therefore much more comparable to the relationship between England and Ireland then that of European colonization of Asia or Africa. Japans push to create colonial industry lead Japan to build a vast network of railroads, ports, and a system of hydro-electric dams and heavy industrial plants around the Yalu River in what is now North Korea. The Japanese to facilitate and manage the industrialization of a colony also put in place a strong central government. Although Japans colonial industrialism in Korea was aimed at advancing Japanese policies and goals and not those of the Korean populace; colonization left Korea with distinct advantages over other developing countries at the end of World War Two. Korea was left with a base for industrializing, a high level of literacy, experience with modern commerce, and close ties to Japan. Japans colonial heavy industrial plants were located primarily around the Yalu River in North Korea. Because of this the North had an edge in industrialization. For many years the North had the fastest growth rates of the communist countries, and its cities were on par with those of Eastern Europe. It was not until the early 1970s that the South surpassed the North in levels of industrialization. Because most of the heavy industrial plants were either located in North Korea or destroyed by the Korean War the groundwork for industrialization that South Korea received from Japanese colonialism consisted mostly of social changes. During colonialism Koreas populace in increasing numbers moved to cities and became urbanized these new urbanites worked in factories and were used to the organization of modern commerce. The Japanese also let a small number of Koreans develop into a semi-elite. Although this group never held powerful positions many of them were educated in Japanese schools, and became either involved in the military or worked as businessmen, bureaucrats, lawyers, and doctors. This elite provided much of the leadership and framework for post World War Two Korean Government in Korea. They had an intimate knowledge of Japanese companies, language, organizational structure, and government. The Korean elites that emerged after the liberation of 1945 and helped steer Koreas economic policies under Park Chung Hee had an intimate knowledge of Japan. Some of them like Park had been educated in Japanese schools, some had worked for the Japanese, and nearly all of them spoke fluent Japanese. It was this closeness to Japan both geographically and culturally that made it natural for the Koreans to use the Japanese model of industrialization when Japans economy boomed in the 1960s and 1970s. The leaders of Korea were ambivalent about relying on Japan, on one hand they felt a profound respect for Japan and its successes and on the other a deep hatred for what Japan had done to Korea in the past. But Japan still served as a model for Park Chung Hee who normalized relations with Japan in 1965 and turned to Japan for technology, equipment, and a model for development. Some nationalistic Korean scholars say that Japans colonialism slowed Koreas growth by exploiting Korea and disturbing its economy. But these views of Korea ignore the fundamental role that Japans policies of industrial colonialism played in allowing Korea to Industrialize during the 1960s. .udd2080a26ffe9f1de158b0db05584f19 , .udd2080a26ffe9f1de158b0db05584f19 .postImageUrl , .udd2080a26ffe9f1de158b0db05584f19 .centered-text-area { min-height: 80px; position: relative; } .udd2080a26ffe9f1de158b0db05584f19 , .udd2080a26ffe9f1de158b0db05584f19:hover , .udd2080a26ffe9f1de158b0db05584f19:visited , .udd2080a26ffe9f1de158b0db05584f19:active { border:0!important; } .udd2080a26ffe9f1de158b0db05584f19 .clearfix:after { content: ""; display: table; clear: both; } .udd2080a26ffe9f1de158b0db05584f19 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .udd2080a26ffe9f1de158b0db05584f19:active , .udd2080a26ffe9f1de158b0db05584f19:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .udd2080a26ffe9f1de158b0db05584f19 .centered-text-area { width: 100%; position: relative ; } .udd2080a26ffe9f1de158b0db05584f19 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .udd2080a26ffe9f1de158b0db05584f19 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .udd2080a26ffe9f1de158b0db05584f19 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .udd2080a26ffe9f1de158b0db05584f19:hover .ctaButton { background-color: #34495E!important; } .udd2080a26ffe9f1de158b0db05584f19 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .udd2080a26ffe9f1de158b0db05584f19 .udd2080a26ffe9f1de158b0db05584f19-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .udd2080a26ffe9f1de158b0db05584f19:after { content: ""; display: block; clear: both; } READ: Anarchy Essay Japans colonialism improved infrastructure, urbanized the nation, educated much of the populace, gave the pubic experience with modern commerce, and indoctrinated Korean elites in the Japanese language and culture.

Japans legacy of colonialism in Korea is felt not only in the many graves and monuments thatattest to Japanese brutality but also in the modern cities of South Korea and the heavy industries along the Yalu River in the North.

Pollution Prevention for Tannery Industry Essay Example
Pollution Prevention for Tannery Industry Paper The assessment identified following pollution prevention opportunities at this facility: recycling the spent chrome tanning wastes, oxidize the sulfide containing wastes, decreasing the volatile organic discharge by changing finishing materials, decreasing water use by batch washing, and using solid wastes from the waste stream as fertilizer. Chromium recycling. This step allows the collection of the spent chrome Nanning solutions, without dilution or contamination, for use in the pickle and tanning process. Since the tannery also tans splits, the spent chrome tanning solution can be used here as well. The tanning of splits results in very good fixation of chromium, so the concentration of chromium in the final effluent should meet effluent regulations. This system results in a saving of about 25 percent in the chromium chemicals used. Solvents. The suppliers of finishing products have developed water-based lacquers with significantly lower volatile solvent contents. These materials are now widely accepted as quality products, and their use is strongly advised. Process Water. In some hide wetting processes there is an opportunity to recycle the final rinses. The final rinse wastewater in this process is compatible with fluids used for the first wetting of the hides. Solid Waste. Elimination of solid leather waste discharges through the use optimizing in reconstituted leather will ease the burden on landfills. Capital Intensive Modifications. Eliminating sulfides from the effluent is very important, as they will corrode pipes, cause objectionable doors, and may cause fatal accidents.

These collected wastes can be placed in a tank and the sulfides oxidized by air with a catalyst. This method is effective and can destroy the sulfide in 4-8 hours. At this point the lime waste, with high BODY and suspended solids, can be used to neutralize the acid wastes that are being continuously discharged. The acid and alkaline wastes from the tanning process will react to produce a expectoration of much of the suspended lids and BODY. This is done with a mixing tank and automatic pH control. Coagulants can also be added at this point. The neutral streams can then flow to a primary clarifier for the removal of suspended solids as sludge. The sludge can be dewatered in a sand bed to more than 50 percent solids for disposal. Although this effluent is somewhat high in BODY, over 80 percent of the pollution load have been removed. The sludge is a good soil conditioner, and if used as such, will eliminate possible high disposal costs. Secondary Treatment. In the future, a secondary treatment system can be added for BODY removal. The secondary system need only be as large as needed for the clarified wastes, and it may consist of a trickle filter, a secondary clarifier, and/ or a filter press. Environmental and Economic Benefits implementation of the suggestions will lead to a number of positive environmental and economic benefits. Chromium recycling will decrease the chromium in the discharge by 80-90 percent. It decreases chromium to less than 3 MGM/l. Costs were estimated at $20,000 (US), savings at $60,000 per year ND therefore payback period of 4 months. The reduction of volatile solvents will decrease VOCE releases to the atmosphere by 60-90 percent. Changes to water usage patterns will decrease effluent volume by 20-40 percent. Elimination of solid leather waste discharges through the use of trimmings in reconstituted leather eases the burden on landfills. This decrease leather waste by 60-80%. Costs were estimated at $1 0,000 (US). Destroy sulfides by air oxidation decreases sulfide wastes by 95- 98 percent. Costs were estimated at $30,000. (US) With primary and secondary treatment, the BODY an be reduced by 75 percent.
