Auditory system and optical system Essay Example for Free

Auditory system and optical system Essay Two of the most important sensory systems in human body are optical system and auditory system. Optical system or sometime called visual system involved in the process of taken amount of stimuli and transfer it into some figure that we can perceive as images that make senses. Auditory systems involved in sound wave that transduced by drum ear into some kind of vibration that eventually gets converted back into wave what we perceive as noise. There are a lot of similarities in their mechanisms of how they gather, carry and prepare those informations from sensory neurons. However, there are also a lots of differences on how each system operated and where does it takes information into difference area of the brain. For both systems, optical and auditory, the information comes from our environment in many forms. For example, optical system detected all still images and image in motion as far as human eyes can see. The auditory is ready to absorb any noise or sound for twenty-four hours a day. Their structures and mechanisms are similar in a way they gather information, prepare and perceive those information into something that make sense in our brain. After the sensory neurons carry information into specific system each detect, transduce and coding those information before they being send to central system, the brain. Both systems have similar structure that transmit those information to the final destination, the brain. Even though, both system basic the same. Each system perceive those information that perceive from sensory neuron in totally different way. For instance, optical system receive visible spectrum of wave of electromagnetic radiation. The frequency of wave created color and distinguish brightness by amplitude. In auditory system, the frequency of wave created tone ( pitch) and loudness by amplitude. For the optical system, the cornea gather light rays that pass into inferior of the eyes. The information such as light’s brightness, hue/color or motion are translate into coded neural impulse. The codes then carried by optic nerves to the brain. However, the information from one side are send to the opposite side of hemisphere but stimuli go to the same side hemisphere. The optical information are stored in occipital lobes where it was process and try to make sense of those information base on experience and individual perception. For the auditory system, the sound’s wave goes through the ear canal and hit the ear drum. They activate the the drum and the information being send through the fluid as a result it bents the hair cell in the cochlea and the information then translate into neural impulse. The intensity of sound waves determine by how many hair cell are fire as well as how frequently they fire. The auditory information then carried by auditory nerve from one side of the ear are sent to the opposite hemisphere. The auditory information are stored in temporal lobes where it was process and try to make sense of those information base on past experience and pattern. In conclusion, the optical and auditory systems have basically the same structure and mechanism but they both different in how they gathering, preparing, detecting, and translating those information. Each system are unique and unbelievably complex structure that we need to learn more. Auditory system and optical system. (2016, Jun 17).

The American Cultural Myth, America as the Land of Freedom and Essay

The American Cultural Myth, America as the Land of Freedom and Equality - Essay Example The given paper will discuss the American myth and reality and prove that the equal rights the United States provides are still to be got by people in a long and difficult struggle. The question about the reality of American equality is rather controversial. This controversy comes from the miscomprehension of what is meant by equality and freedom and how it is realized in the American society. The myth is that the United States of America represents the place where everybody is â€Å"free†, so he can do everything that comes into his mind. In reality, freedom and equality are really present in America, however, people who come to the state usually feel shock because of the official and bureaucratic limitations, and face difficulties on their way to become a part of the American society. During its history, the United States regulation has been doing its best to counterpoise the independence of a person with the welfare of the country and the outcomes of such efforts sometimes appeared to be rather strange and unexpected. Anti-smoking law that states that those who do not smoke have a right to live without smoke that restricts the right of smokers’ to smoke represents the perfect example of this strangeness. Young people who come to America to study are usually unpleasantly surprised by a great number of regulations that controls each step they make. The social principles in America are really strange. They represent a mix of Puritanism and the commonly nonjudgmental American approach that generates a lot of difficulties for newcomers, because they can’t foresee the American society’s reaction to their actions. Furthermore, in America various ethnic groups live one next to another and each group has its own principles that may differ much from the values of other. Consequently, the newcomers often feel that there are absolutely no rules in the United States and appear at a

The preaching ministry of Heinrich Bullinger Research Paper

The preaching ministry of Heinrich Bullinger - Research Paper Example Life of a Preacher 5. Highs and Lows of his Life in Zurich 6. Conclusion 1. Introduction Heinrich Bullinger was a well-known Swiss reformer who was the head of the Zurich church as the successor of Huldrych Zwingli. Most researchers show how different he was form the earlier generation of reformers such as Martin Luther and Ulrich Zwingli. Bullinger was rather a consolidator; he added his own perspective to the theology and was a genius to think beyond just gathering the gospel riches that the people of Switzerland craved. Hence, it is believed after being long underestimated, that without him, the shape of theology of England in the late sixteenth and early seventeenth century would have been unimaginable1. Bullinger is known for being one of the most influential theologians in the history and specifically in the Protestant Reformation in the 16th century. The life of Bullinger indicated how he had been raised for priesthood. His father was a Catholic priest and though he was a prie st, he had married, mainly because of the loose enforcement of the vows of celibacy. Bullinger was the youngest of five sons. Bullinger’s parents are not much discussed, but the fact the Bullinger’s father came to confess on the doctrines of the Reformation when he was very old, is known. This may be probably because of the influence of his gifted son2. 2. Early Life Eventually Bullinger started with his formal education in the school of The Brethren of the Common Life in Cleves. While his education, his father gave him no money as he believed that his poverty is necessary for him to develop good habits and responsibilities in his life. However, like Luther, Bullinger was also subjected to sing to earn his living. Bullinger also wanted to enter a Carthusian monastery during his studies, but he was put off against his brother. And he rather set off to Germany to attend the University of Cologne when he was 15 years of age, as his parents expected him to follow the clerg y just as Luther3. Bullinger went through many of the experiences and formations of his life while he was in Germany. It was in Cologne when he started studying about the scholastic theologians of the middle Ages. Soon he became disgusted of them, and rather turned his way to the church fathers, specifically Chrysostom and Augustine. He was involved in the lives of the church fathers and eventually became inspired by their writings, especially by their abundant use of Scripture. Prompted by the determination of the church fathers to ground all their doctrine in God’s Word, Bullinger turned his direction to the study of Scriptures4. Thus, as he involved himself more in the pleasure of reading Scriptures, he went through the writings of Martin Luther and used to be inspired by them greatly. These writings used to revolve throughout Germany at that time and thus Bullinger involved himself immensely in this world. It is these years of study in Germany that Bullinger spent and bec ame one of those whose life was surrounded by the winds of reform that were let loose by Luther5. On returning to Switzerland with his master’s degree in 1522, Bullinger accepted the call by Wolfgung Rupli to teach in the cloister school. As he was already influenced by the thought of Reformation, he taught the monks form the New Testament and from Philip Melanchthon’s Loci Communes, which was considerably the first systematic theology of the Reformation. He also initiated the systematic

Education and the Digital Divide :: essays papers

Education and the Digital Divide Closing the digital divide involves many components, starting with the education program and teachers. While schools are integrating new technologies into their programs, teachers are supposed to keep up with the latest technologies and use them in their curriculum to teach students. According to a U.S. Department of Education Report (1999), only 24 percent of new teachers felt sufficiently prepared to integrate technology into the curriculum they were using (Brogan, 2000). The problem is, many teachers did not grow up with computers and are not receiving the training they need to operate them (Brogan, 2000). Starting work as early as 7 a.m. and leaving school as late as 5 p.m. to go home and do even more work, leaves teachers lacking the time to learn new technological skills. Many schools offer training programs for teachers. For example, the Palm Beach County, Florida school district teaches Web basics for teachers at middle schools and magnet schools (Brogan, 2000). This i s a great idea because it is giving teachers the opportunity to learn about technology and it is showing that the school district is interested in helping its employees become better at what they do. Andy Carvin states â€Å" internet access in schools isn’t worth a hill of beans if teachers aren’t prepared to take full advantage of technology† (2000). Schools spend a lot of money on computer hardware and software as well as other technologies without realizing that many of their employees are unprepared to include them in their teaching and use them to their advantages. Educators often use technology as a classroom management tool rather than an educational one, allowing computer time as a reward for good behavior (Clark & Gorski, 2001). The problem with this is that students learn to use the computer for games and such because it is their reward instead of using it on their own time for educational purposes. This is teaching them the wrong idea. Margaret Honey, director of the Center for Children and Technology in NYC said it best, â€Å"The bottom line is, you don’t just put technology into schools or into homes and expect miracles to happen. The technology is only as good as the program that surrounds it† (Meyer, 2002, p.2). â€Å"Education is probably the most important issue that affects the ability to benefit from technology.

After doing a preliminary search of keywords â€Å"work related stress,† I found that the National Institute of Occupational Safety and Health, the Center for Disease Control (CDC), Oxford university's medical department, the US National Library of Medicine and the National Institute of Health all maintain sites which will be useful as sources for me. All of these sites are administered by well-known and legitimate organizations and loud be excellent sources of accurate and reliable information.They also include the results of professionally conducted clinical research studies. Additionally, the same keyword search conducted In the university of Phoenix library resulted In 330 sources available for research utilization. By focusing on these numerous sources, I will find relevant and unbiased studies and material directly specific to work-related stress. An overview of my research strategy process is s ummarized as follows: – Identify and select the problem/topic. I have already decided my topic will be â€Å"Work-Related Stress†.Find and Identify the symptoms of the work-related stress that are common to the ma]orally of people affected by work-related stress and not to a specific career field or occupation. – Find and identify the common causes that are relevant to the majority of people and not a specific career field or occupation. – Find and identify both long-term and short-term health risks and benefits, if any, related to work- related stress. – Identify the treatments available to reduce or eliminate work-related stress. Any medication prescribed for the treatment of stress must be approved by he Food and Drug Administration(FDA).Pipeline or experimental medication will not be considered. ; Develop conclusions related to the above research. – Summarize research findings and conclusion in the form of a written report. In order to e ffectively get the most reliable information regarding work-related stress, I will utilize credible publications, books, articles, Journals and studies and I will reference all cited data. Utilizing both the Internet and the University of Phoenix library, I will search for, locate and compare legitimate data and studies to find profession.Different Jobs have different stresses and stress levels and I am trying to capture the common theme behind work-related stress as a general topic. I will verify the source of any potential research information by conducting some background checks on the author to ensure that they are experts in their field. Once I have located and identified what I feel to be relevant data, I will compile the information for comparison. Only material meeting my specific research parameters will be utilized in order to ensure consistency and accuracy throughout all phases of my project.While conducting my research, I will combine both quantitative and qualitative r esearch methods in order to ensure that my findings are reliable, unbiased and objective. Because I am not focusing on a specific career field or occupation, I will ensure that my research is objective and can be reproduced by data supported through studies and research conducted on people from various backgrounds, locations and professions. By comparing data collected from the different studies meeting my criteria, I will be able to effectively utilize consistent data and eliminate irregularities or other material not applicable to my particular search focus.The symptoms, causes and health risks must be consistent in all studies. Additionally, hours spent at work and work environment should be varied to ensure that the common causes and stresses are captured. Since my topic is medically related, my research will be more effective by utilizing the most recent information and studies available. Medical technologies and research can evolve rapidly and therefore make older data and mat erial obsolete very quickly. Obtaining the most recent and credible material will be key for my research topic.For the retirement portion of the research, I will limit studies to natural remedies or medication approved by the FDA. After combining and comparing all data that is applicable to my research of work related stress, the material will be reviewed again for accuracy and also to ensure that all material is objective. Conclusions will be drawn based on the findings and the results will be presented in a written report.

The Roman Empire How The Evolution And Growth Of Roman...

The Roman Empire: How the Evolution Growth of Roman Society Altered Christianity Rome was powerful, strong and had power over their people and they held on to it. Rome craved power along with control, eliminating any potential threats, no matter the size. Rome’s population was heavily influenced by its religion to control the population and to glorify the emperor. Rome developed Christianity in several big ways; the first being lowering women s status and influence within the Church. Once Christianity had been established as the dominant religion of the Roman Empire, many males began to succeed women in their roles as religious leaders. However the greatest way Rome helped transform Christianity was using Jesus as a way to help legitimize the emperors rule and sway public opinion. Roman emperors often used Jesus to help legitimize their rule therefore aiding i n the spread of the Christian faith throughout the Empire and to other territories. Jesus is humble, born to be a perfect man to walk on the earth. Jesus made many miracles come true to people to grow his ministry of God. In the Bible, the book of Matthew says all about Jesus’ life and the growth of his words and his name. Jesus is born in 4 CE, born of the virgin Mary and the Holy Spirit. At age 27, he delivers the Sermon on the Mount to a congregation of five thousand people.

History of Scuba Diving and Pioneer Jacques Cousteau

Modern scuba diving gear consists of one or more gas tanks strapped to the divers back, connected to an air hose and an invention called the demand regulator. The demand regulator controls the flow of air so that the air pressure within the divers lungs equals the pressure of the water. Early Diving Gear Ancient swimmers used cut hollow reeds to breathe air, the first rudimentary snorkel used to enhance our abilities underwater. Around 1300, Persian divers were making rudimentary eye goggles from the thinly sliced and polished shells of tortoises. By the 16th century, wooden barrels were used as primitive diving bells, and for the first time divers could travel underwater with more than one breath of air, but not much more than one. More Than One Breath In 1771, British engineer, John Smeaton invented the air pump. A hose was connected between the air pump and the diving barrel, allowing air to be pumped to the diver. In 1772, Frenchmen, Sieur Freminet invented a rebreathing device that recycled the exhaled air from inside of the barrel, this was the first self-contained air device. Freminets invention was a poor one, the inventor died from lack of oxygen after being in his own device for twenty minutes. In 1825, English inventor, William James designed another self-contained breather, a cylindrical iron belt attached to a copper helmet. The belt held about 450 psi of air, enough for a seven-minute dive. In 1876, Englishmen, Henry Fleuss invented a closed circuit, oxygen rebreather. His invention was originally intended to be used in the repair of an iron door of a flooded ships chamber. Fleuss then decided to use his invention for a thirty-foot deep dive underwater. He died from the pure oxygen, which is toxic to humans under pressure. Rigid Diving Suits In 1873, Benoà ®t Rouquayrol and Auguste Denayrouze built a new piece of equipment a rigid diving suit with a safer air supply, however it weighed about 200 pounds. Houdini Suit - 1921 Famous magician and escape artist, Harry Houdini (born Ehrich Weiss in Budapest, Hungary in 1874) was also an inventor. Harry Houdini astonished audiences by escaping from handcuffs, straitjackets, and locked boxes, often doing so underwater. Houdinis invention for a divers suit permitted divers, in case of danger, to quickly divest themselves of the suit while submerged and to safely escape and reach the surface of the water. Jacques Cousteau Emile Gagnan Emile Gagnan and Jacques Cousteau co-invented the modern demand regulator and an improved autonomous diving suit. In 1942, the team redesigned a car regulator and invented a demand regulator that would automatically fresh air when a diver breathed. A year later in 1943, Cousteau and Gagnan began selling the Aqua-Lung.
