...The Clocks Within Us Analysis According to the article published in the February 2015 edition of the Scientific American, genes in the brain, liver, pancreas, and other tissues help keep the various parts of the body in sync. These ideas are portrayed throughout the article written by Keith C. Summa and Fred W. Turek, “The Clocks Within Us.” The article is based around circadian rhythms, which describes how the body works around 24-hour cycles. Both authors are extremely validated when it comes to informing the public on circadian rhythms. Summa is a PhD at the Northwestern University Feinberg School of Medicine and is interested in understanding how to apply research findings to clinical medicine. Turek is a neurobiologist and director of the Center for Sleep and Circadian Biology at Northwestern. He is also the founding president of the Society for Research on Biological Rhythms. Learning more about the different clocks in the body can help explain bodily disruptions caused by out of sync cellular clocks. Circadian rhythms are important in the world of biology because of their effects on one’s health. When all the clocks in our body are not in sync, we can experience diabetes, depression, obesity, and more. The clocks could fall out of sync when sleep and eating patterns falter. This information could have been presented in the Scientific American, a popular magazine that is read by many people across the nation, because many people change their daily patterns. For example...

...I. Introduction The first time you will hear the word Circadian Rhythm, you will be dreary because you have no idea on what it is about, but because of my drastic intention I will gather more ideas about my topic. Doubtless, I am sure I will make it easier to work with it. One question was bothering me and makes me persevere on doing this Research Paper. “Is it entrainable or not?”, one question with different ideas and information’s sticking with it. No specific and particular reviews I need to provide about it, I just need to gather information by means of researching just to know if Circadian Rhythm is entrainable or not. Although the process is not easy, as people who have suffered from a jetlag, because the more time you did not sleep, the more you will suffer Circadian Rhythm. Sleep and waking, for instance, occur naturally to the beat of an internal pacemaker, which works on a cycle of about twenty-four-hours. My purpose on making and researching is to have broad ideas and I need to answer the question bothering me if it is entrainale or not. I need to defend my title against myself to be proudly to present it and defend it easily.In my title, I used the questioning type because I want to know if Circadian Rhythm is truly entrainable or not. Y abstract focuses on the summary of my entire research paper and what are my goals and objectives on making this research. In listing the methods and procedures, my goal is to give the reader sufficient...

...Communication Introduction During the process of communication there are several things that you can differentiate about nonverbal and unwritten communication. When you are talking to someone or someone is talking to you, you will understand by their body language and facial expressions if they are interested in what you are saying “Communication is an exchange of information via verbal or written messages and is the process of sending and receiving messages.” (Cheesebro, O’Connor, and Rios, 2010) Nonverbal cues Non- verbal cues are used in everyday interactions and can often times speak louder than verbal communication. Think back to childhood how momma’s eye contact was understood and nothing had to be said and what she wanted was done just by the look she gave. How about in school? Students were instructed to raise their hands when asking or answering a question. Teachers understand these gestures. The same is true in business where managers and employees communicate frequently through expectations; for instance the time clock is a symbol for receiving an accurate pay check. Employees want to be paid so they punch the clock. Managers want to acknowledge punctual employees so they review time sheets generated from time clocks. In essence demonstrative communication is of great importance and is an essential part of communication. A well respected leader will have more power with non-verbal communication than with verbal, in the military ranks, only the presence of an official...

...1898 IEEE TRANSACTIONS ON VERY LARGE SCALE INTEGRATION (VLSI) SYSTEMS, VOL. 22, NO. 9, SEPTEMBER 2014 Active Mode Subclock Power Gating Jatin N. Mistry, Member, IEEE, James Myers, Bashir M. Al-Hashimi, Fellow, IEEE, David Flynn, Senior Member, IEEE, John Biggs, Member, IEEE, and Geoff V. Merrett, Member, IEEE Abstract— This paper presents a technique, called subclock power gating, for reducing leakage power during the active mode in low performance, energy-constrained applications. The proposed technique achieves power reduction through two mechanisms: 1) power gating the combinational logic within the clock period (subclock) and 2) reducing the virtual supply to less than Vth rather than shutting down completely as is the case in conventional power gating. To achieve this reduced voltage, a pair of nMOS and pMOS transistors are used at the head and foot of the power gated logic for symmetric virtual rail clamping of the power and ground supplies. The subclock power gating technique has been validated by incorporating it with an ARM Cortex-M0 microprocessor, which was fabricated in a 65-nm process. Two sets of experiments are done: the first experimentally validates the functionality of the proposed technique in the fabricated test chip and the second investigates the utility of the proposed technique in example applications. Measured results from the fabricated chip show 27% power saving during the active mode for an example wireless sensor node application...

...April Fabro English 200B Professor Taufer 29 May 2012 An Explication of William Shakespeare’s Sonnet 12 When I do count the clock that tells the time, And see the brave day sunk in hideous night; When I behold the violet past prime, And sable curls all silver'd o'er with white; When lofty trees I see barren of leaves Which erst from heat did canopy the herd, And summer's green all girded up in sheaves Borne on the bier with white and bristly beard, Then of thy beauty do I question make, That thou among the wastes of time must go, Since sweets and beauties do themselves forsake And die as fast as they see others grow; And nothing 'gainst Time's scythe can make defence Save breed, to brave him when he takes thee hence. William Shakespeare’s Sonnet 12 is written in an iambic pentameter in the Shakespearean format. It is a contemplation of one’s progression of life and the absolute emergence of ones death, with an ultimate purpose to convey the answer of an individual receiving eternal life. The sonnet is a short narration of definitive mortality that focuses on the passing of time through metaphoric images of nature and through the description of ones youth evolving into the dreaded phase of old age. It is a brief description of the passing of time here on earth. It showcases the passing of time in three quatrains: the end of youth, the end of the harvest season, and the end of ones life. The poem emphasized the importance of...

...Rocks were brought back from the Moon by the Apollo Astronauts. They applied the techniques to date rocks on Earth to the Moon rocks. Radioactive day was used to determine the age of the rocks. The radioactive atoms decay into daughter atoms. Therefore, the more daughter atoms there are the older the rock is. Radioactive elements with half-lives we have determined can help scientist get a more accurate nuclear clock. We have used this data to determine the age of the Moon as well as the Earth. They both formed about 4.5 billion years ago. We also concluded that colliding planetesimals formed the Earth’s moon. Earth and another body collided and the Moon formed from the left over...

...Benjamin Crowell THE MOTION OF FALLING OBJECTS The motion of falling objects is the simplest and most common example of motion with changing velocity. The early pioneers of physics had a correct intuition that the way things drop was a message directly from Nature herself about how the universe worked. Other examples seem less likely to have deep significance. A walking person who speeds up is making a conscious choice. If one stretch of a river flows more rapidly than another, it may be only because the channel is narrower there, which is just an accident of the local geography. But there is something impressively consistent, universal, and inexorable about the way things fall. Stand up now and simultaneously drop a coin and a bit of paper side by side. The paper takes much longer to hit the ground. That's why Aristotle wrote that heavy objects fell more rapidly. Europeans believed him for two thousand years. Now repeat the experiment, but make it into a race between the coin and your shoe. My own shoe is about 50 times heavier than the nickel I had handy, but it looks to me like they hit the ground at exactly the same moment. So much for Aristotle! Galileo, who had a flair for the theatrical, did the experiment by dropping a bullet and a heavy cannonball from a tall tower. Aristotle's observations had been incomplete, his interpretation a vast oversimplification. It is inconceivable that Galileo was the first person to observe a discrepancy with...

...Can Your Body Tell the Time of Day? (NOTE: If you have thought of a statistics project that you would prefer to tackle instead of the one described below, contact me. I’ll try to make an equivalent project using your particular topic of interest.) Objective: You will measure how body temperature and reaction time vary throughout the course of a day, as well as related questions. In particular, you must address each of the questions below. Question 1: At what time of the day is the body temperature highest? When is it lowest? How much difference is there? Are body temperatures between midnight and noon significantly different than body temperatures between noon and midnight? Question 2: At what time of the day does reaction time peak? When is it the worst? How much difference is there? Are reaction times between midnight and noon significantly different than reaction times between noon and midnight? Questions 1 & 2 again: According to William Garrett, "Reaction time peaks in the early evening at the same time as the maximum body temperature. This is partially because the nerve conduction velocity increases 2.4 meters per second (m/s) for every 1°C increase in body temperature." (Garret, William E., Exercise and Sport Science. New York: Lippincott Williams & Wilkins, 1999, p. 354.) Do you agree or disagree with Garrett? Question 3: Is there a strong relationship between the reaction time measurements from the “Sheep Tranquilizer Game” and the “Hit the Baseball Test”? Question...

...Running head: Internal Control and Risk Evaluation Internal Control and Risk Evaluation The purpose of this brief is to identify and analyze possible risks, internal control points, design internal controls, evaluate the application of internal controls and discuss other outside controls, that Kudler Fine Foods may need to upgrade the computer systems. Analysis of Risks of Computer Systems After reviewing the previous flowcharts it is recommended that Kudler Fine Foods automate more of its accounts payable, accounts receivable, inventory, and payroll processes and standardize these processes across all Kudler locations. Therefore, increased computer controls will be needed to ensure the security of data. Computer data could be compromised if proper computer controls are not in place. Risks include theft of confidential and sensitive information stored on computer servers such as company bank account information or personnel records of Kudler clientele and staff. If proper internal controls are not implemented breaches of sensitive data stored in folders that are accessible through the Internet will be exposed through file sharing software with the other Kudler locations. Identify risks and internal control points Identifying risks and internal controls are imperative when information systems are used extensively throughout the fundamental business processes. Information systems general controls are the policies and procedures that apply to all...
