Paper on the Wire

...The Wire Paper “The Wire” was a television program that aired on HBO from 2002 – 2008. It has received 2 Emmy nominations and is a critically acclaimed program that had received very positive reviews when it was still on the air. The characters on the program, both criminal and judicial, are all well-developed, rounded characters that help to display a realistic view of life in Baltimore, Maryland. One of the criminals on the program is a man named Omar Little. Barack Obama stated that Omar Little was his favorite character on the program: “He is not my favorite person, but he’s a fascinating character– a gay gangster who only robs drug dealers and then gives back. But he’s the toughest, baddest guy on the show, and he’s gay. He’s a fascinating character” (Goldman, 2009, p. 1). After watching several episodes of The Wire, it is easy to see why people like this character, even though he is a known criminal who has committed robbery and murder several times. Omar Little is a homsexual, black male, who is seen spending time with boyfriends, yet, he goes against the gay stereotype of being sensitive, and kind, and is one of the most dangerous criminals in Baltimore. He isn’t afraid to pull the trigger of his gun, and he participates in robberies of dangerous drug lords as well as getting involved in inter-gang rivalries. He displays a passion for poetry, and for Greek mythology (shown in Season 2). For a character like Omar Little to be understood, it is important to realize......

Resistance of a Wire

...metal wire, together with the physical dimensions of the wire, from which you will calculate the resistivity of the metal. Theory The resistance R of a component in a circuit is given by the equation V = IR where V is the potential difference across the component and I is the current in the component. The resistance of a wire is given by the equation R = ρl / A where ρ is the resistivity of the metal from which the wire is made, l is the length of the wire and A is its cross-sectional area. Using the circuit below, you will make measurements of current and voltage for different lengths of wire.

The Wire

...in, and tells her about his friend, Artie, she replies by saying “he calls her [Artie’s mother] everyday”. Through this, she implies that she wants him to call her, just like his friend calls his mother. There is no sign of any malignant feelings she might have toward Tony. We simply see her as a mother, trying to get some attention from her son. She does not seem like someone, who by the end of the season would “take a “contract” out on her son” . Joseph Walker says , “Livia’s every utterance, however casual, has the potential to disrupt Tony’s precarious sense of his selfhood. Her barbed “look who calls his mother,” or “oh, he knows everything,” addressing Tony in third person rather than second person, objectifying him as effectively as the scene in Melfi’s waiting room, symbolically fragmenting him into observer and observed .” However, seeing it from a different angle, when Tony calls Livia from Bada Bing!, her first comment on the phone (09:35) is, “look who calls his mother”, telling us that she feels so abandoned by her family that she is surprised when Tony calls her. She might even believe that this might have been caused by her comment to him about how Artie calls his mother everyday, and not because Tony actually wanted to talk to her . When Livia find out the Tony is seeing a psychiatrist in Season 1 Episode 7, at first she doesn’t believe it. When she finally does accept it, her immediate response is that he goes to talk and complain about her. She......

Alternative Splicing

...It has been suggested that alternative splicing plays a forefront role in creating a complex collection of expressed sequences (mRNA) from a smaller number of genes in humans. In fact, Walter Gilbert had expressed that a variety of mRNA isoforms of one gene arises from different combinations of exon-splicing known as alternative splicing (Modrek & Lee, 2002). Alternative splicing can be classified into several types, with each type being different among species. Exon skipping is a type wherein a cassette exon and its bordering introns are spliced out of the transcript. This type is prevalent in higher eukaryotic forms. Two other types of alternative splicing are alternative 3’ splice site (3’ SS) and 5’ SS selection in which two or more splice sites are identified at one end of an exon. These two types account for a small percentage of alternative splicing in higher eukaryotes. Another type of alternative splicing is intron retention, characterized by an intron persisting in the mature mRNA transcript. It is the rarest type of alternative splicing in both vertebrates and invertebrates, but the most prevalent in plants, fungi, and protozoa (Keren et al., 2010). In the wake of discovering these alternative mRNA forms that diversify protein functions of the same gene, there, however, exists a problem of how to differentiate truly functional forms from those that are not, biologically or otherwise, which further opens up an avenue towards the risk of outright designating a......

Machanical vs Splicing

...Machanical vs. Fusion Splicing Mechanical splicing involves using mechanical fixtures to align and connect optical fibers. Mechanical splicing methods may involve either passive or active core alignment. Active core alignment produces a lower loss splice than passive alignment. However, passive core alignment methods can produce mechanical splices with acceptable loss measurements even with single mode fibers. In the strictest sense, a mechanical splice is a permanent connection made between two optical fibers. Mechanical splices hold the two optical fibers in alignment for an indefinite period of time without movement. The amount of splice loss is stable over time and unaffected by changes in environmental or mechanical conditions. If high splice loss results from assembling some mechanical splices, the splice can be reopened and the fibers realigned. Realignment includes wiping the fiber or ferrule end with a soft wipe, reinserting the fiber or ferrule in a new arrangement, and adding new refractive index material. Once producing an acceptable mechanical splice, splice realignment should be unnecessary because most mechanical splices are environmentally and mechanically stable within their intended application. The types of mechanical splices that exist for mechanical splicing include glass, plastic, metal, and ceramic tubes; and V-groove and rotary devices. Materials that assist mechanical splices in splicing fibers include transparent adhesives and index matching gels...

Investigation of the Resistance of a Wire

... In this investigation I am going to investigate what affect the resistance of a wire. Electricity flows in metals. Metal wires are made of millions of tiny metal crystals. Each crystal’s atoms are arranged in a regular pattern. The metal is full of ‘free’ electrons that do not stick to any particular atom. They fill the space between atoms in a metal. When these electrons move they create an electric current. Conductors have resistance, but some are worse than others. The free electrons keep bumping into atoms. A wires resistance depends on four main factors which are: Resistivity The length of the wire Cross sectional area The temperature of the wire I am going to investigate how the length of the wire affects the resistance. I have done a preliminary experiment to help me decide the best way to do my investigation. The results should also help me make a prediction. Preliminary Investigation Below are my results from the preliminary experiment (see table 1). I have taken three readings each from the Volts and current to make sure it is as accurate as possible Table 1 From the results I can see that as the length of the wire increases, the resistance increases as well. Furthermore I have noticed that if you double the length of the wire, the resistance is roughly doubled. E.g. when the length of the wire is 20cm the resistance is 3.14 ohms, when the length of the wire is 40cm the resistance is 6.18 ohms which is roughly double 3.14 ohms. In my main......

When we think of sexuality, we might just think about our bodies. We might just think about our sex organs. But our sexuality has as much to do with how we think and feel as it does with how we behave. Sexuality is a basic part of our physical, mental, emotional, and spiritual lives. Our sexuality should be enjoyed and celebrated. It is not something to be ashamed of or embarrassed about. Healthy sexuality allows us to be open, flexible, creative, safe, and responsible as we explore our sexual thoughts, feelings, and desires. It lets us recognize that sex can be fun and can also fulfill many emotional needs. Sex also has risks. Having a healthy attitude about sexuality means knowing our values, beliefs, attitudes, limits, and boundaries, and respecting that knowledge by being responsible. It allows us to feel attractive, regardless of our age, gender, sexual orientation, race, religion, height, weight, or physical or mental ability. It lets us be ourselves. Knowing as much as possible about our sexual selves, in terms of our beliefs, values, and physical needs will help us create responsible, healthy, and satisfying......

Besides the differences in race, we can determine using this data, scenes from “The Wire” and Wilson’s theory described in When Work Disappears that the structural changes that were occurring at this time in the port neighborhoods caused an increased in unemployment and poverty. The rise in poverty and unemployment increases the amount of crime and criminal activity. In episode three Nick’s feeling of frustration and pressure increases in response to being turned down from work that day. In a conversation with Zig, (The Wire Season 2 Episode 3 – Hot Shots dialog begins at 20:18). Nick, feeling desperate for money, rants about his frustrations from lack of work and the pressures from Aimee.

The Evolution of Wire Services.

...Abstract This paper explores the origin of wire services, major new agencies providing those services, and the evolution of the service over its history. Wire services are necessary for the facilitation of news internationally. The methods of providing news from a wire service, or news agency, to other newspaper, periodical, radio, television, or other communication outlet has evolved throughout history. This paper explores the humble beginnings of wire services and highlights several of the major wire service providers, including Reuters, The Associated Press (AP), United Press International, Agence France Presse (AFP), and Bloomberg. The Evolution of Wire Services: Then and Now Wire services are integral components of international communication. Also referred to as a news agency, a wire service is an organization “that sends out syndicated news copy to subscribers by wire or by satellite transmission (Mish, 1997).” With origins dating back to the early 1850s (McPhail, 2010), wire services have not always conducted communication transfers with advanced technology like satellite transmissions. From telegraphy to teleprinters to radio, the process of getting news from a wire service to its dependent news and other providers has evolved substantially throughout the years. The conception and continued modernization of wire services can be attributed to various agency titans, including Reuters, The Associated Press (AP), United Press International, Agence France Presse......

Wire Extraction

...WIRE DRAWING Objective To know how copper and aluminum drawing is done, and also to understand the machine setting and how the machine operates. Introduction Wire drawing is the process by which a metal rod is forced through a series of varying cross section die(s) and hence the metal rod cross sectional area is varied so as to obtain the desired shape and size. In Kenwest cables company their are 3 wire drawing machines namely:- 1. M55 2. H20 3. M85 1.M55 This is the main copper drawing machine and the one which can handle the 1st drawing process which is hard drawing. The raw material used is usually copper rod of 7.9mm thickness as the hard drawing material. The M55 can also handle further copper drawing like the H20. Operation procedure The M55 has several units namely:- a) stand b) block c) drawing basin d) annealer e) spooler a) stand It is responsible in guiding the copper rod being fed to the block or drawing basin. If its hard drawing its fed to the block but when its further drawing its directly fed into the drawing basin. This is because at the block section the die obtained may have a larger diameter than the copper rod in the case of further drawing hence the block is not required. b) Block It is functional when hard drawing takes place. The 1st die is usually located in this section (the block section) hence drawing process begins at the block section. The copper rod being fed is usually about 7.9mm in diameter which is the diameter...

Controlling Alternative Splicing

...Controlling Alternative Splicing via Cell Signaling Pathways On November 18, 2014, Dr. Kristen W. Lynch’s seminar topic was about how the cell signaling pathways can control the process of alternative splicing. Dr. Lynch’s started the seminar by mentioning that about 95% of human genes undergo alternative splicing. Those genes that undergo alternative splicing further change the Open Reading Frame (ORF). ORF is a reading frame of nucleotides that begins with start codon and ends with stop codon, which can translate into polypeptide chains. Therefore, Lynch’s gave the example of how the alternative splicing of CD45 gene alters in the production of different mRNAs that further produces different proteins (polypeptide chains). Thus, the difference in the production of functional protein (tyrosine phosphatase protein) has played the role in the regulation of development and maturation of T-cells, a lymphocyte cell. The difference in the production of tyrosine phophatase protein is due to the variation in alternative splicing of exon 4, 5 and 6 of CD45 gene in T-cells. Multiple signaling pathways that are induced by antigen signaling in turn regulate the alternative splicing. Some of the multiple signaling pathways that Dr. Lynch had mentioned are RAS (G-protein), Glycogen Synthase Kinase-3 (GSK-3) and c-Jun (c-Jun N-terminal Kinase or JNK) signaling. However, Dr. Lynch had illustrated the GSK-3 and JNK signaling pathway. In GSK-3 signaling, PSF is phosphorylated. PSF usually......

The purposes of the meeting are to elect directors for the ensuing year, ratify the appointment of auditors for 2015, to approve, in a non-binding advisory vote, the compensation of the Company’s named executive officers and conduct other business that may properly come before the meeting. Net sales for the year ended December 31, 2014 were $1.167 billion, while net income for the year was $37.1 million, with fully diluted net earnings per common share of $1.78. Unit volume, measured in copper pounds contained in the wire sold increased 3.6% in 2014 versus 2013. Our new aluminum building wire plant finished its second full year of operations, during which we sold $103.4 million of aluminum building wire. We believe that our ability to sell aluminum wire has resulted in increased copper wire sales as customers prefer to “one-stop shop” and order enough pounds to get free freight. Aluminum demand is so strong that we are expanding the current 200,000 square foot aluminum plant with a 250,000 square foot addition. We believe that our costs are as low, or lower, than our competitors. We believe our superior order fill rates continue to enhance our competitive position, as our......
