The topic is about how brains are different from computers. Computers are normally recognized as “electronic brains,” and newspaper articles as well as science fiction, talk of “intelligent machines” that take over from humans. These statements are misleading. I will observe the differences between brains and computers by examining the difference according to various researchers. For now, brains are said to different from computers –but there is a chance for us to learn from studies that examine the way that brains process information, this will be observed in the study. Computers do not have the ability to think the ...

Reflection and Refraction of Light

REFLECTION: Reflection of light is the change of direction that light experiences when it collides with an object and "bounces." The reflection of light makes it possible to see objects that do not emit their light . There are several applications of the reflection. One example is the "The Laugh House" of an amusement park, the person will probably see a very distorted image in a curved mirror. Similar deformations occur in the concavity of a shiny spoon or on the polished surfaces of a coffee machine or a car. Images look different due to irregular surface curvature; They have ...

The Theme of Dystopian Society in the works of Orwell, Huxley, and Bradbury

Introduction All the three books, 1984 that was published in 1948 and written by George Orwell, Aldous Huxley’s Brave New World that was written in 1931, and Ray Bradbury’s Fahrenheit 451 are the examples of dystopian literature. Dystopian literature is the kind of fiction that offers a negative perspective on the society of the future and the problems which are likely to be faced by humankind as a result of their political, environmental and economic activities. While utopian fiction portrays the future being advanced and prosperous as a result of the improvement of technology that assists them ...

At common law, a felony murder was defined as the unlawful killing of a human being while in the commission of a felony crimes (LaFave). However, the modern concept of felony murder has widely been interpreted to mean an unlawful killing that occurred in the commission of only a certain type of felony crime, or acts that are deemed, by the totality of circumstances, to be inherently dangerous (LaFave).

My Great-Great-Aunt Discovered Francium. And It Killed Her

The scientific discoveries that were made in the past were without any doubt full of risks and repercussions associated with the exposure to the radioactive materials that resulted in the damage to the bodies and over exposure to radiation led to the death of the researchers. Some researchers were enthusiastic about discoveries that they tend to ignore the long-term repercussions they may have to face due to their exposure to toxic materials, and Marguerite Perey was one of them. She mixed in different materials and ingredients and applied different theories without any care and concern regarding the contamination of ...

CT scanning is a medical process that uses accurate x-rays in medical imaging of organs inside the body. The process is fast, accurate and can detect internal injuries, diseases, and hemorrhage. CT scanning involves producing images in different planes including 3-D, which can then be observed on a computer screen, in print or copied to a DVD. This method is more favorable than traditional x-rays because it is more detailed and can be easily manipulated by a physician. CT scanning provides excellent details of internal body organs, bones, soft body tissues, and blood vessels. CT scans can diagnose conditions ...

In his essay entitled “The Decay of Laying”, author Oscar Wilde wrote that “life imitates art far more than art imitates life” (Wilde, 1891). One of the biggest questions that Wilde’s quote created was whether he was right, and life truly does imitate art. Regardless of whether he is accurate or not, art, including television, is often studied to provide understanding of how life was perceived at the point in time when the art was produced. This essay will analyze five episodes of a family situational comedy (sitcom) from the 1950s, 1970s, 1980s, 1990s and 2000s to provide ...

Parents are homeschooling their children, and many of the reasons are evident such as the fact that children are more likely to listen to their parents than complete strangers. Other reasons could be that some parents have given up on the school system and their ability to provide a decent education, another reason could be ethical or the school system’s lack thereof to deal with some children especially those who are bullies. The pressure of trying ...

When attempting to find trace amounts of an inorganic substance x-ray diffraction would be a valuable tool for discovering just what substances were present. It would not be the first choice according to various researchers, but it would be one of the least invasive as well as one of the least likely to destroy the sample. By using x-ray diffraction it is possible to differentiate between substances, making it easier to identify trace elements that can be found in crime scenes. X-ray diffraction is a valuable but slightly limited technique that is used by forensic science thanks to its ...

Question 1

Spectrometry would indeed be a good analytical tool since it will help in distinguishing the different compounds in the powder. In such a case, the best type of spectroscopy would be infrared spectrometry and mass spectrometry. Infrared spectroscopy is a vital analytical tool to identify controlled substances. Infrared light is passed on the unknown substance. As the sample absorbs the infrared radiation, an infrared spectrum results, which is a series of peaks and valleys ("Physical Evidence Handbook Drug Identification Unit", 2016). Each substance in the compound results in a highly accurate infrared spectrum. The spectrum of the unknown elements ...

From those times, we greatly progressed, but still we did not conquer this magnificent source of power. Why ...

The relationship between traditional organizational structures of policing agencies:

According to Gaines & Worrall (2012), all police organizations regardless of their size or location have a social structure. The social structure of a police organization is composed of the relationships between the members of the organization. Social structures play important roles in the organization. They form the basis for division of work among the members of the police force (Gaines & Worrall, 2012). They also serve other functions such as the way to socialize new members of the force into the police force. Traditionally, the social structure of police forces focuses on three dimensions. These are vertical, functional, and geographic ( ...

Monomorphic Ventricular Tachycardia

Cardiac arrhythmias often require immediate medical care that may include resuscitation (Ray, 2004). The diagnosis of cardiac arrhythmias can be challenging particularly in situations whereby the patient is asymptomatic and ECG findings are normal between symptomatic episodes (Cruickshank, 2008). Distinguishing between supraventricular and ventricular tachycardia is also a challenge (Australian Resuscitation Council, 2008). Cardiac arrhythmia should be suspected in patients with a history of syncope, near syncope, palpitations, and/or chest pain (Cruickshank, 2008). This paper will justify why monomophic ventricular tachycardia is the most likely diagnosis of a male patient who collapsed abruptly and has hypotension (BP 63/38), tachycardia ( ...

Introduction

Lung cancer is the uncontrolled growth of abnormal cells that starts in one of the lungs or both. In most cases, the cells develop in the air passages. The cells divide rapidly forming tumors, which may grow to extremely large sizes making it difficult to supply the oxygen to the bloodstream. There are tumors that remain in one place and do not spread, which are well known as benign tumors. There are malignant tumors, which are more dangerous as they easily spread to other body parts. When the cancer disaster spreads further, it may become extremely difficult to treat.
