...Anthony Rios 2/27/12 Composition 1 Vox Amplification: A History The Vox Amplifier Company are makers of guitar amplifiers that boast a history in rock and roll music, and with the invention of the electric guitar musicians were not only amplifying there guitar but exploring new frontiers. The Vox Empire and JMI (Jennings Musical Instruments) started with just two men by the names of Thomas Jennings and Dick Denney. Thomas Jennings was always interested radios and electronics as well as an amateur accordion player from there he took his interests and joined the British Army, where he was a part of the Royal Electrical and Mechanical Engineers. Sometime in 1942 he received a medical discharge and took a job at a munitions plant in Dartford Kent, England. While working at the plant he met a big band guitarist and fellow musician Dick Denny. Denney, who was also interested in electronics and radio technology, would befriend Jennings and the two would on occasion play together during air raids to keep the morale up. With the war still waging on in 1944 Jennings and Denney would go their separate ways and Jennings would start a small part time business selling second hand instruments and doing repairs. Around this time his business was growing fast and so was he needs to find a bigger commercial venue. It was 1946, the year after the war ended, is where he would open his first commercial premise mainly importing accordions and other musical instruments but also inventing new...

...Crime and Society – Moral Panics Lecture 07.12.15 Moral panics lecture will cover; the concept of moral panics, some possible reasons behind moral panics, the politics of a moral panic and also look into some moral panics case studies. Cohen (1972) studied ‘Folk Devils and Moral Panics’ and this was known to be the first systematic study of moral panics within Britain. He studied the social disturbance of the mods and rockers in Britain, during Easter Bank Holiday, in Clacton, the Summer of 1964. Groups of working class youths began arriving in Clacton, and this was a traditional holiday meeting place for youths form the East End of London. Facilities for young people were limited at the time, and some café owners, despite the already poor conditions, refused groups of youth’s entry to their establishment. There were minor scuffles, which eventually lead to massive brawls. The media allowed the story to receive front page news throughout the national press. They blew the story way out of proportion. According to Cohen most youths didn’t actually own a motorbike or scooter and had actually got there via train. Rivalry was mainly about regional identity, and argues that the amount of actual serious vandalism and violence, was actually on a small scale. Shortly after events, local journalists admitted the events had actually been over reported. Media outrage had set in motion a chain of responses, which initiated a wider level of public concern. This lead to the police...

...Although investing in a car stereo can at times be a difficult task, especially for individuals making their first purchase, and those who have little knowledge on the subject, it can also turn out to be a fun experience, and a great way to spend a Saturday or Sunday. Before you hit the stores in search of a good deal, do some research on the web in order to get a good idea of what you need, and help ensure that you receive the best deal possible. If you are new to this experience, it's a good idea to start by reviewing and understanding all the components of a car stereo. This will allow you to have a clearer idea of which components you would like for your car. Let's start with decks. Car stereos need a deck in order to function. An example of a deck is a CD player, or an MP3 player. This part of the system is considered the main component that holds the entire car stereo system together. The overall output of the sound is controlled through the deck, and it is what allows you to control the music being played. All car stereo decks have a minimum 4-channel output, meaning that you will be able to route the sound of your car stereo through a minimum of four speakers. If you need or want more power than what your deck can put out, you may want to consider purchasing an amplifier, which might mean that you will need additional speakers. Amplifiers are esential components that provide the power needed to drive more volume through your system, enabling you to "blast" the music...

...organisations. First coined by Jock Young (1971:37) in his book ‘Images of Deviance’, edited by Stanley Cohen, his peer and colleague. It was Cohen (1973:9) though, in fact, who brought the phrase to the forefront of sociology and defined it when he said: Societies appear to be subject, every now and then, to periods of moral panic. A condition, episode, person or group of persons emerges to become defined as a threat to societal values and interests; its nature is presented in a stylised and stereotypical fashion by the mass media (Cohen 1973:9). This paper assess’ Cohen’s’ ‘moral panic’ as a useful notion for explaining increased social anxiety about criminal behaviour using his work on ‘mods and rockers’ and Wilkins (1964:90) ‘Deviancy Amplification Feedback Loop’, a cyclic process that alienates perpetrators and increases sensitization to their actions creating more frequent arrests and often harsher punishments. Moral panics come and go and more often than not the ‘problem’ has been around for many years before it becomes accepted as a phenomenon that requires attention and reform. Often these moral panics are scapegoats of bigger issues in society (Goode & Ben-Yehuda, 2002:26). Such as Dungeons and Dragons (D&D) in the 1980’s being blamed for youth suicide in America after James Dallas Egbert III and Irving Pulling shot themselves in 1980 and 82 respectively, leading Pulling’s mother to set up B.A.D.D...

...preferred mode of communication (they both indicate they use simple signs and gestures to communicate with Zoey), and her hearing aids likely are not being fit for her current level of hearing loss. In order for Zoey to increase her spoken vocabulary, she needs constant input. The family needs to understand that no matter what mode of communication they choose for Zoey, she will need constant input. If the parents are committed to constant vocal stimulus, cochlear implants could give Zoey the intensity she needs to effectively communicate with her family and her peers. The cons to changing her current amplification are the family will have to spend a lot of time giving Zoey constant auditory input and will have to learn about a new device. Changing her current amplification to a cochlear implant device, would require invasive surgery and therapy after the surgery. Changing the amplification device can be very emotional and financially tolling for a...

...Robert Kremer is a 77-year-old male who has a binaural, sensorineural hearing loss. He has had this hearing loss since he was 7 years old. Robert hearing loss has progressed and he is need of stronger amplification because he relying more on visual cues. In order to make Robert’s quality of life better, I have made some recommendation to best treat his condition and lifestyle. Since Mr. Kremer has not had an audiological testing in the past five years, I would like to retest his hearing before making my final recommendation. I will test both ears individually. I will get a most recent case history for Mr. Kremer and I will do an otoscope examination to look at Mr. Kremer’s tympanic membrane and middle ear structures. I will use the Pure Tone Average test and Speech Reception Threshold to get pure to get Air Conduction and Bone Conduction information. I will also use Word Recognition Testing. I would assume that Mr. Kremer’s hearing would be about the same degree, if not worse after five years. I would also send Mr. Kremer to get a CT scan to make sure there are no physical abnormalities in his hearing system....

...the benefits and detriment possibilities of amplification, Briggs et al. (2011) formulates a similar conclusion regarding the lack of benefit amplification provides, however, the article expands on the research explaining both the objective and subjective outcomes amplification may have to offer. By using objective as well as subjective measures, Briggs et al. (2011) aims to determine if traditional amplification in the poor ear would be beneficial for children with a unilateral hearing loss. The study indicated that the current suggestion for children with a unilateral hearing loss entering school is the FM (frequency modulated) system. The FM devise is the only technology that will increase the word recognition in noisy and quiet environments. The study took 8 children 7 to 12 years of age who had permanent mild to moderately severe unilateral hearing loss and no other impairments. The children were fit with the same hearing aid, which was programed to their loss and verified on the audio scan. All of the aids had only one program and the volume control was disabled. The objective test measures used were the BKB-SIN and NST for speech perception. The subjective measures used were the CHILD, LIFE Student, and HEAR-QL for the child, LIFE Teacher, and SIFTER for the child’s teacher and the CHILD Parent for the child’s parent. Both the objective and subjective measures were analyzed prior to amplification and 3 months post amplification. In regards to the objective measures, the...

... Abstract Polymerase chain reaction (PCR) is greatly used in molecular genetics. It entails amplification of a single DNA strand into millions of similar DNA fragments. It involves three stages in each cycle. It is repeated to about 30 cycles. This method is vital as it is used in various processes such molecular identification, genetic engineering, and sequencing. The three stages in each cycle have varying duration and temperature. A thermal cycler is involved in the regulation of temperature in various stages. Over time, various modifications have been done to PCR technique so that it can be applied in specific roles. The PCR has been of aid in the diagnosis of diseases and other numerous applications. In the near future, PCR will be advanced and perhaps replaced by better techniques. Nevertheless, PCR will remain critical for future advancements in molecular genetics. Introduction Polymerase chain reaction (PCR) is broadly employed by scientists in biochemistry and molecular biology. Thus, its essence cannot be underestimated in the development of genetic analysis and gene manipulation. The technique was established by Karry Mullis in the early 1980s. It entails amplification of a single or several DNA fragments into millions of identical copies of DNA. The process is done by repeated number of cycles that range between 30 to 40. This results into a chain reaction...

...recover the DNA from the cells. DNA is recovered in the form of a pellet. The pellet may be used immediately or can also be stored for analysis later on. DNA isolation can be performed using the protocol mentioned, or alternatively, the AUTOMATIC DNA ISOLATION system can also be used. Automatic DNA Isolation is faster and also provides better quality and quantity of the samples. 3. PCR amplification and fluorescent tagging: After the extraction, since the amount of the DNA recovered is low, it is necessary to amplify selected portions of the DNA for further analysis. This can be done by multiplex PCR. Multiplex PCR is the simultaneous amplification of different sequences present in the DNA. STR loci that are required for DNA profiling are amplified using this technique. Multiplex PCR is followed by the fluorescent tagging of the amplified sequences with different probes. Tagging is necessary for the STR analysis of the loci. PCR amplification is performed by the Automatic Multiplex PCR kit. The kit has primers for the STR sequences used for the forensic analysis. 4. STR Analysis: After amplification and tagging of the STR loci, it is necessary to analyze the sequences for the presence or absence of core and additional loci used for forensic analysis. This is done by using a genetic analyzer. The genetic analyzer uses capillary electrophoresis technique. The smaller sequences are detected before the larger ones. As the sequences reach the detector window, they are fluoresced by the...

Successful supply chain management requires a change from managing individual functions to integrating activities into key supply chain process; hence, accurate information is of essence. One of the key factors that can adversely affect effective and efficient supply chain process is information distortion. Demand forecasting and ordering policies have been recognized as two key causes of bullwhip effect in supply chain management. This study explored the simulation approach in quantifying the effect of bullwhip in supply chain, using various forecasting methods. ____________________________________________________________ ...

...polymerase chain reaction can be used to amplify both double and single stranded DNA. In order to perform PCR, one must know at least a portion of the sequence of the target DNA molecule that has to be copied. Generally, PCR amplifies small DNA targets 100-1000 base pairs (bp) long. It is technically difficult to amplify targets >5000 bp long. A pair of single stranded oligonucleotide primers, which have DNA sequences complementary to the flanking regions of the target sequence, must be synthesized. The primers are complementary to either end of the target sequence but lie on opposite strands. The primers are usually 20-30 nucleotides long and bind to complementary flanking region at 3' end. Requirements: Thermal cycler (thermocycler) PCR amplification mix typically containing: Sample dsDNA with a target sequence Thermostable DNA polymerase Two oligonucleotide primers Deoxynucleotide triphosphates (dNTPs) Reaction buffer containing magnesium ions and other components Procedure: 1. The DNA molecule carrying a target sequence is denatured by heat at 90-95oC for 20 seconds. The two strands separate due to breakage of the hydrogen bonds holding them together. Oligonucleotide primers are added. 2. A reaction mixture containing all four deoxynucleotide triphosphates (dATP, dCTP, dGTP, dTTP) and a thermostable DNA polymerase is added. A DNA polymerase (Taq) that is not denatured by the...

...distinguish bacteria and represent the microbial diversity of the sampled elliptical. An estimate of the cleanliness of the elliptical will be made based on species-abundance as well as evidence of any pathogenic strains. We will also compare and contrast respective populations of bacteria on clean and disinfected ellipticals to assess disinfectant effectiveness. Methods We collected bacteria from the elliptical, purified and amplified the total community DNA, and then analyzed the sequenced DNA with Mi Seq Software. A revised protocol was used to extract, purify, and sequence the community DNA; these methods were followed without deviation (1). The procedure to sequence and configure the data is described on Blackboard (2). Results PCR amplification of the community DNA product was unsuccessful. There was no evidence of PCR amplified DNA on the gel (Figure 1.1). An alternate gel from Molecular Microbiology Laboratory was used as a model to perform gel electrophoresis of the community DNA (2). A plot of migration distance vs. size that includes the Invitrogen ladder can be used to determine the size of the PCR amplified community DNA (Figure 1.2).
