...Cold Rolling Jeffry S. Asher DT1410 Unit 4 Assignment 2 ITT Technical Institute January 18, 2016 Cold rolling is a metal forming process in which the shape and the structure of steel are altered through drawing, extruding, hammering, pressing, rolling, spinning, and stretching at temperatures below the steel's recrystallization point, usually room temperature. These processes result in changes to the metal's composition which permanently increases its hardness and tensile strength, and improve the surface finish, but decrease ductility and impact resistance. After hot rolling, many steel products undergo a further processing in the cold state. This stage of processing may not necessarily alter the shape of the steel, but it does reduce its thickness and significantly improve its performance characteristics. Hot rolled coil is commonly known as cold rolled, also known as cold reduced. Cold rolling is a process by which the sheet metal or strip stock is introduced between rollers and then compressed and squeezed. The amount of strain introduced determines the hardness and other material properties of the finished product. The advantages of cold rolling are good dimensional accuracy and surface finish. Cold rolled sheet can be produced in various conditions such as skin-rolled, quarter hard, half hard, full hard depending on how much cold work has been performed. This cold working hardness is often called temper, although this has nothing to do with heat treatment temper...

But there still record stores out there and when you find one it is like a diamond in the coal. I arrived \ on a less then pleasant day the weather was cold and rainy so before I left the safety of my car I turned my collar up to face the cold and made a bee line to the store so fast it would but Usain Bolt to shame. When I walked in the store I was greeted by the smell of coffee and sound of The Rolling Stones song Monkey Man playing over the store speakers with the owner of the store john singing along to the song and throwing his arms up like a monkey. As soon as you walk into the store your face to face with a giant rack of used DVDs ranging from Driving Miss Daisy to the Texas Chainsaw Massacre I was immediately welcomed by john who sitting down in front of this cash register with a sign on it that read “No Personal Check$” behind him was a giant poster of Frank Zappa which seemed like one of his most prized positions john had on a tie dyed rolling stones shirt john had looked tried and he seemed to be discomfort later I found out he looked that way due to having MS.

...such as Nucor are shut out of the flat sheet market because with conventional steel-making technology, the minimum efficient scale for flat sheet production is too high, with optimal capacities for each plant reaching 3 million tons per year and investment costs close to $2 billion. In contrast, minimills typically only produce 800,000 to 1 million tons per year, with investment levels closer to $300 million. The cost advantages from thin-slab casting are substantial. If viable, thin-slab casting minimills could become a category killer in the flat sheet segment. For hot rolled flat sheets, the operating costs per ton for a thin-slab minimill is 14% less than a modernized integrated steel mill, and 25% less than an unmodernized mill. For cold rolled flat sheets, the cost advantages are even more dramatic – with thin-slab minimills costing 19% less than a modernized steel mill, and 30% less than an unmodernized mill. 1 Thin-Slab Minimill Hot Rolled Sheet Operating Costs per Ton Revenues per Ton Income per...

...com/wp-content/uploads/2013/07/rolling-stone-the-bomber-ftr.jpg Terrorist’s a Visual Reality Magazine covers have always been known to push the limit. It’s a fantastic marketing ploy to grab the attention of consumers. Think about it, you are walking down an aisle or standing in line at the market to check out, what is going to stand out more to you and easily grab your attention? Is it going to be a magazine cover with a modestly dressed man or women? Or perhaps a magazine cover with a provocative Miley Cyrus or a cover with an extremely, well known very hated face for example? The more absurd or obscene the image the faster and more likely it is going to grab our attention. The Rolling Stone magazine cover did just that when their August 1, 2013 issue was released headlining the Boston bomber, Dzhokhar Tsarnaev. There are numerous reasons why the majority of Americans were enraged by the cover choice the Rolling Stone’s made, but I’m not one of them. To be in the entertainment industry and land the cover of the Rolling Stone magazine is an honor. “It goes without saying that if you are featured under those two journalistically iconic words, than you have made it” (International Business, Times. “Rolling Stone Cover Sparks.”). The band Dr. Hooks even wrote a song about wanting to be on the cover of the Rolling Stone; “But the thrill we’ve never known, is the thrill that’ll getcha when you get your picture, on the cover of the Rollin’ Stone” (Silverstein). However, the Rolling Stone magazine...

...ARTS AND ENTERTAIMENT JOURNALISM Did you have another boring day at a press conference? Interview a rock star Eccentrics, selfish, narcissists, capricious, fanciful, fussy, obsessive, passionate; some times genius, some other times schizophrenics. There are many adjectives that can be successfully used in order to describe a rock star personality. The idea of meeting and having a conversation with a rock star is exciting and intimidating at the same time. Even for those who work as professional journalists it is a challenge as avoiding this natural tendency, especially when the celebrity you are interviewing has had a real impact on your life, may be troublesome. Although, as Clayton (1994) points out, journalists must remember that they cannot be overawed by a Big Name. In his own words, “they are not meeting a celebrity as an adoring fan, but on a business” (1994:60). The aim of this essay is to critically analyze the interviewing process by going throw several interviews with rock stars, considering that the approach taken would be slightly different from that of other interviewees. The interviews examined concentrate on print, but it is impossible to ignore broadcasting (media) as many aspects of the interviews such as occasional silences, body language and questions order what would otherwise be missed. First of all, it is worthy to introduce the myth of the rock community. Frith (1981) stresses the importance of this point because for most rock bands “music...

Music combines different aspects of American social and cultural identity, through economic status, race, gender, religious beliefs, and sexuality. There are many different types of music listened to. Religious, race and economic status is just a few. Economic status is the wealthier people tend to listen and attend symphony concerts while the middle class and poor listen to folk music, country, pop, and rock again are just a few of them. New styles of music come our way about as often as a new generation comes of age. The American youth culture of the 1960s saw many changes and was very complex. A number of factors attributed to this. This generation was the largest by number of this age group ever in history. American culture up until that time was stereotyped so to speak, there were many set ideas youth were expected to follow. Upon graduation from high school you either went to college or got a job, got married and settled down to raise a family. The youth of that time had different ideas; they wanted to experience most everything that they could. They wanted the freedom to express themselves...

...My grandmother was special. I hadn’t known her my whole life so it was like meeting a new friend. My mother always said that she “adopted” us as her family because she didn’t have one. I didn’t really understand it at the time because, well, I was only 7 years old. All that mattered to me was that I had a new grandma, a new friend. The first time I meet Velma was at her apartment in down town Sarnia. The door squeaked and the smell of lilacs filled the entrance way. The apartment was small, but was very nice.. She smiled sweetly and introduced herself. I was very shy at first, but there was something about her, something told me we where going to be best friends. I visited her almost every week, and everyday we would do something different. Shopping was usually on Tuesdays, Lunch and a movie was on Wednesdays, and on Fridays we went bowling. We became a lot closer over time. She always had a reassurance about her that made me feel comfortable, I didn’t have to pretend. A few months later my mother came to me with some upsetting news. Velma was in the hospital. She wouldn’t tell me why but I could tell that it was bad by the worried look on her face. We visited her soon after, and I had no idea what to expect. We walked in with the nurse and I saw her laying there in the bed, motionless. She tried to talk but her voice shook and trembled. I was scared; I knew she was too. I visited her less often now because I was busy with school and sports. When I did, she looked happier...

...I picked “(I Can’t Get No) Satisfaction” by Rolling Stones. The song released in 1965 and Mick Jagger and Keith Richards wrote it. The song starts with a guitar riff that consists three notes. This melody continues until the end of the song and it is very catchy. Lyrics are presented in a rhythmic way in the beginning and they have like a call and response relationship with the guitar. I choose this song for my paper because I listened to a lot of songs for this paper but this song has the most memorable melodies in terms of the lyrics and the guitar for me. The song starts with a close range melody in the first verse but it opens in the first bridge. Moreover, when we arrive to the chorus, it becomes a wide ranged melody and the chorus is definitely higher than the verse. From the verse to the chorus, this increase in the melody is building an expectation and it gives a natural feel of build up. Especially the bridge is getting higher and higher into the chorus. As a result, the melody is lifting before arriving the chorus, building a great approach to the chorus. The wide range of the chorus is giving the listeners a rebellious feel and it supports the lyrics. Moreover, there is prosody throughout the song. The song based on the three-note guitar riff and the lyrics are very similar to the pattern. The lyrics are using some long notes with some sharp, staccato notes like the guitar riff. Particularly in the chorus, two staccato notes are occurring in the same time with...
