Johnny Tremain essays

Johnny Tremain essays In the face of adversity, our character can change extremely. Ester Forbes writes about this example in her book, Johnny Tremain, which takes place in Boston, Massachusetts, in 1773, during the revolutionary war. As we read the book, we see Johnny facing many obstacles and problems causing him to start a different and new life. However, Johnny encounters bad luck, but he learns to understand his problems better and accepts them. Johnny Tremain starts out as a arrogant boy who one day wants to be a silversmith. Unfortunately one day, he was in a silversmiths shop and injures his hand from burning hot silver, which causes him to deeply damage his hand. He no longer could be a silversmith. Of course, Johnny was deeply ashamed of his hand and always hid it from the world. Gradually, he then has the courage to show his hand. Johnny felt no more shame over his burned hand -pg. 254- Later, Johnny comes across the printing press of the Boston Observer while looking for another job. While there, Johnny gets the chance to meet Rab and immediately makes friend with him. Johnny than notice that he enjoyed telling Rab stories about his hand, but with nonce of the belligerent arrogance which he had been answering the questions kind people had put to him. - page 146- This is the first time since the accident he felt able to stand aside from his problems to see himself. - pg. 255- Rab turns his life around and shows him another world that he could and must face. Without Rab, Johnny might not have believed in himself and achieved much. A big influence on Johnnys life were his friends. As previously mentioned, Rab contributed much to Johnnys life. Rab has shown Johnny that he could achieve anything he waned too. Rab taught Johnny how to ride Goblin, gets ...

North vs South - How the North won the Civil War Essay

North vs South - How the North won the Civil War - Essay Example Further, people wonder why the North failed to allow the Confederacy to secede peacefully. This paper will examine the military strategies and leadership, which facilitated the victory that the North enjoyed and the defeat of the South. There was an increasing discrepancy between the South and the North in terms of economic development, social structures and organizations and political ideologies. However, the two regions were alike during the founding of the new nation. Slavery was in the entire states, and the economic activities of the two regions had strong reinforcements from agricultural prosperity (Steele & Herbert 1996, p. 45)1. The Northern states designed a plan that would end slavery and enhance the emancipation of the slaves to ensure that they fought for their rights, freedom and liberty. Further, the collapse of the party system had remarkable contribution towards the victory of the North; the slavery issue received undue suppression from the laws of this party. The strength of the political parties had a negative influence from massive immigration of foreigners and debates pushing for the prohibition of slavery. There existed a deficiency in the governance of the states; the strong parties suffered from utter blows that weakened the running of the parties. The confederacy and the union had confidence that they would win the war with a lot of ease (Hattaway & Jones 1991, p. 63).2The two regions believed that their outstanding advantages over the other side would bring ultimate victory to them. On the side of the confederacy, they believed that they had a better position to win the war because the Generals from South had advanced training, and most of the whites on that side were conversant with firearms and horses. Further, the South had plans of fighting a defensive war against the Northern region, and enjoy foreign economies, which meant that the economic might of the south

Computer Graphics Essay Example | Topics and Well Written Essays - 1250 words

Computer Graphics - Essay Example [Wallace, 2001. pp3-6] The JPEG compression algorithm involves three stages - Colour Space Conversion (Red-Green-Blue triplets mapped to Luminance-Chrominance Blue-Chrominance Red triplets), Segmentation into 8x8 pixel blocks, and Discrete Cosine Transformation (image transformation from spatial domain to frequency domain representation) encoding stage that includes Quantization (sorting the output waveform of DCT), Zigzag Scan (sorting the frequency coefficients from low to high), and Entropy Coding (Huffman Coding and Arithmetic Coding). The encoding and decoding algorithms for JPEG images are shown in figures 1 and 2 respectively. Compression is used to reduce the file sizes such that they can be used on web pages or documentation or any other light weight graphics applications. The 8x8 blocks of source images are first shifted from unsigned integers to signed integers and then are applied to the Forward Discrete Cosine Transformer (FDCT). To decode the compressed image to achieve the 8x8 blocks again, they are applied to the entropy decoder whereby the output is taken out from Inverse Discrete Cosine Transformer (IDCT). The final processing step of DCT encoder is the entropy coding that achieves additional compression by encoding the quantized DCT coefficients based on statistical characteristics. There are two types of Entropy Coding methods - Huffman coding and Arithmetic coding. Huffman coding requires one or more sets of Huffman code tables whereas Arithmetic coding doesn't require any external tables (althoug h statistical conditioning tables as inputs can improve coding efficiency). The quantization stage of JPEG algorithm results in loss of information, thus making JPEG standard a lossy compression technique. [Wallace, 2001. pp3-6] Compression Ratios and JPEG image formats: Compression is specified in terms of bits per pixel including the chrominance and luminance components) called the compression bit rate. Higher the value of bits per pixel, better would be the image quality. The JPEG standard recommends the following mapping of image quality with bit rates in colored images having moderately complex scenes: 0.25 to 0.5 bits per pixel: The output image shall possess moderate to good quality 0.5 to 0.75 bits per pixel: The output image shall possess good to very good quality 0.75 to 1.5 bits per pixel: The output image shall possess excellent quality 1.5 to 2.0 bits per pixel: The output image shall be practically non-distinguishable from the original image The improved version of original JPEG technology is JPEG 2000 that provides better rate

Police Corruption Essay Example for Free

Police Corruption Essay Every police agency throughout the United States has its own patrol division. The patrol division is often over looked and underrated. In almost every agency, this division is the face of the Police Department. Despite the important role that patrol officer’s play, the role often may be viewed as a low-status area of policing. It is usually the largest section of an agency; however, it receives the most agency funds. The patrol division responds to calls, provides services to the community, and helps to prevent crime. It is a physically and mentally demanding job, in which involves all facets of the policing role (Grant and Terry, 2011). Due to its demanding attention, Patrol Officers respond to a numerous of variety calls. These calls include homicides, rapes, and domestic disputes. An officer may at times be plagued with quick judgment calls, which may affect him in the long run. Community patrolling addresses the community concerns at the grassroots patrol level. As departments grow, they set realistic goals and continue to develop community partnerships. Unfortunately, one will often see patrol officers make bad judgment calls, in which can lead to misconduct issues. Criminal acts under color of law include acts within the bounds or limits of lawful authority. This includes acts beyond the bounds of lawful authority. There has been an increase in police corruption issues, misconduct, and brutality incidents within the last year. Everything from the range of using technology for bad selection in newly hired officers has led to this problem. Off-duty conduct may also be covered under color of law only if the perpetrator asserted official status in some manner. Due to these types of issues, one will sometimes hear the Police Department needs to be policed. A number of researchers have examined the use of force. For example, there are debates for the usefulness of force continuums among law enforcement agencies. As a police officer, I have encountered calls, in which witnesses have question my actions and even accused me of police brutality. I once responded to a call of a possible burglary in progress. Upon my arrival, I located a Hispanic male, in his late twenties, attempting to remove a window screen. When he observed my uniform and noticed who I was, he ran away from me while holding a sharp flat headed screw driver in his right hand. As he climbed over a brick wall, separating the building, I observed he tossed the screw driver and he appeared to reach for a second unknown object. As I climbed over the wall myself, I reached for my taser gun and deployed it. I struck him along the side of his torso and he went down like rain drops on cement. As I subdued him and placed handcuffs on him, I could hear people gathering around saying, â€Å"that Officer did not need to taser him, and this is police brutality. † I knew that because of the wall blocking the civilians view, most of the witnesses had not seen what had occurred on the other side of the wall. Using quick judgment and proper use of force will always be questioned by the community. Unfortunately, not all patrol officers practice good judgment as you may have heard about the Fullerton Police Department relating to the incident with Kelly Thomas. Kelly Thomas, born on April 5, 1974 and died on July 10, 2011, was a homeless man diagnosed with schizophrenia. He lived on the streets of Fullerton, California where Thomas died five days after an altercation with members of the Fullerton Police Department on July 5, 2011. After paramedics treated the officers first for their minor injuries, Thomas was taken to St. Jude Medical Center before being transferred to the UC Irvine Medical Center, where he was comatose on arrival and not expected to recover. Medical records show that bones in his face were broken and he had choked on his own blood (Sewell and Winton, 2011). A judge declined to dismiss the charges against the officers in January 2013, finding that â€Å"a reasonable person could infer that the use of force was excessive and unreasonable. An appeals court judge also denied a request to overturn the lower courts decision. Manuel Ramos, one of the Fullerton Police Officers, was charged with one count of second-degree murder and one count of involuntary manslaughter. Corporal Jay Cicinelli and Officer Joseph Wolfe were also each charged with one count of felony involuntary manslaughter and one count of excessive force. I was not at the incident; therefore, I cannot judge my colleagues in the act ions that were taken on their behalf. However, it is difficult for me to think that any human being deserved this type of force used against him. When dealing with a combative subject I use the only the amount of force needed to make the subject comply. I do not feel that when dealing with a mentally ill transient, the use of strikes to the head and face are needed. As much as I hate to see my colleagues in this position, I feel that this is the closest we will get to justice. Thomas will not return from the dead and someone needs to be punished for the mistakes made that day. Another case I would like to discuss is the Huntington Beach Police Detective, who was accused of corruption. A veteran Huntington Beach police officer was once assigned to a federal anti-drug task force. He was arrested on charges that he conspired with others to distribute large quantities of cocaine and marijuana. Sergeant Alvaro Murillo, who was also known as The Godfather by his cohorts, was accused of using his job as a police officer to recruit informants in the drug world. After this, he would then use them to help him steal narcotics from dealers (Glover, 2008). Unfortunately, we are going to have officers who abuse their authority. It kind of makes me embarrassed to be associated with this type of behavior. As a rookie officer, I was employed by the City of Huntington Beach. I patrolled the streets of Huntington Beach with my Field Training Officer (FTO) where I remembered one incident when he drove me to a house, which had been raided on a drug related warrant search. I observed evidence, which included United States currency, guns, cocaine, crystal methamphetamine, and other drug relating to paraphernalia lying on the living room floor. It is disgusting to see a man fall to temptation, even worse, to see a fellow officer taint our profession by performing such a disgusting act. However, this profession, just like all other professions, is conducted by human beings and human beings make mistakes. A key factor in being a good police officer is using good discretion and having integrity. Sergeant Murillo was sentenced to prison to do time for his action. I agree with this punishment, no matter how bad temptation is. As Police Officers, we are held to a higher expectation. If one is tempted by the minor temptations in life and needs to corrupt one’s police department to reach financial gain, then the individual has no business in this profession. As a rookie officer, I remember an old Sergeant briefing the patrol division at 0500 hours. The last words of his briefing were, â€Å"be safe and do the lords work. † By being associated with police corruption, misconduct, and excessive force, one is working with the evil forces of nature in which where one swore to protect against the negative influences. By staying away from those immature acts, it has made me a better officer and an overall better human being.

Perspectives on Fear :: Personal Narrative Writing

â€Å"At the University of California at Irvine, experiments in rats indicate that the brain’s hormonal reaction to fear can be inhibited, softening the formation of memories and the emotions they evoke† (Baard). Sometimes I have trouble sleeping. I lie in bed for hours while my mind churns through endless streams of fragmented thoughts and memories, bits of brain matter that I do not have time for in my waking life. I have tried the homeopathic remedies. I drink â€Å"calming† teas, take showers, and inhale scents advertised to promote sleep and relaxation. I even have a lavender neck pillow. Nevertheless, when I am inflicted with a bout of sleeplessness, there is usually very little I can do but wait it out. I stay away from sleep drugs. The streetlamp outside paints shapes across the wall next to my bed. I can see them in the darkness, dull orange lines that have become familiar in my many restless nights. At the heart of their canvas, they intersect to form a rectangle. A rectangle? For months I believed in this reality of form with the inborn certainty that accompanies that which is obvious. I didn’t have to think about it. Nightly, I would study the shape in a sleep haze, unconsciously harboring knowledge of its regularity. Except that it is not a rectangle. Two forty seven. Nearly three hours after my first attempt at sleep, I stared up at the wall and realized for the first time the distortion within the orange light. Where the lines connected to form the shape, the rectangle, were angles. Obtuse and acute, they had none of the symmetrical regularity that geometry dictates of a true rectangle. The outline on the wall was crooked, skewed, an imperfect representation of the form. I tend to think of my memories as shoeboxes, precise, neatly uniform components that stack tidily in the mind. Somehow I have trained myself to believe that in regularity and order I will uncover the diagram of my true self, a clear-cut explanation for all that I think, say, and do. But in sleepless nights I realize that even old recurring thoughts can be strangely misshapen, and I am thrown into a tailspin. My memories of experiencing fear seem contorted. Among the most vivid of my recollections, they stand out with their potent doses of color, emotion, and experience. They have been with me so long that I rarely question the nature of their composition.

Powdered Coconut Husk, Okra Mucilage, Water Hyacinth and Starch as Alternative Plastic Composites Essay

The present condition of our country regarding the use of plastics demands that people explore other means whereby proportionate products can be produced out of raw materials which are commonly disregarded. One of these is the utilization of solid wastes which could yield excellent useful results. Largely an agricultural country, Philippines provides various local raw materials, the utilization of which may lead to the country’s industrialization. Philippines provide ample farm products having great possibilities for some purposes. An example of which is the coconut husk fiber or cocos nucifera. Although some use this for making native products, this study used this for an alternative bioplastic product making it more different than the usual ones. Water hyacinth, which is commonly found almost in some rivers and considered as another solid waste is to be used also in this project study. Although it has the same function as the coconut husk fiber, this is used to lessen the number or amount of water hyacinth in our environment because of its abundance and bad effects. To improve the quality of the bioplastic product,the researchers used okra wherein mucilage can be found which lessens the brittleness of the said product because of the so called, glycirin. Another concerned material in the study is cornstarch. It is the source of polymer which is said to be the building blocks of the eco-friendly plastic product. What makes this study different is that the researchers used raw materials which are seldomly used in a more different way and utilize it to make a new product which could yield useful results. Moreover, the main purpose of this study, is to make plastic that can be decomposed easily since it uses raw materials, to use starch instead of chemicals and to utilize some of the solid wastes in our society. Plastic is a versatile and potentially indestructible material, which makes it ideal for a number of commercial and household uses. Indeed, plastic has become a substitute for many items which used to be made from other substances, such as plastic bottles for drinks, condiments and many other more. In many cases, this is extremely useful and convenient. However, usage of plastic has caused many environmental downsides. This is because, plastic is so resilient that even burying it deep within the Earth doesn’t keep it from impacting the environment. Although plastics can be recycled, many people still burn them and we all know that it is harmful to the environment. It may also affect people’s health because plastics contain many chemical additives which causes illnesses like endocrine disruption which can lead to cancers, birth defects, immune system suppression and developmental problems in children. And worse it can also lead to toxicity of living organisms and marine animals. This ecological problem impelled the development of new materials that can be substitutes in producing biodegradable plastic which led us to think the utilization of eco- friendly materials that can be an alternative in making bioplastic. Scopes and Limitations The research study was concerned with utilizing coconut husk fibers or cocus nucifera and water hyacinth in producing a bioplastic product. The research focused not only on the simple production but also the quality of the said product in terms of brittleness and flexibility. Mucilage was obtained from okra where glycirin is found and improves the brittleness of the product. Furthermore, this study is also concerned in using cornstarch as the source of polymer considered as the building blocks of the product. Statement of the Problem The purpose of this study is to produce an alternative plastic made up of organic materials. Another purpose of this study is to answer the following questions: 1. What will be the organic material used in making the plastic? 2. What content(s) is/are most effective in making the bioplastic more efficient than than Plastics- any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, but many are partially natural. Biodegradable Plastics- plastics that will decompose in natural aerobic (composting) and anaerobic (landfill) environments. Biodegradation of plastics occurs when microorganisms metabolize the plastics to either ssimilable compounds or to humus-like materials that are less harmful to the environment. They may be composed of either bioplastics, which are plastics whose components are derived from renewable raw materials, or petroleum-based plastics which contain additives. Glycerol- (or glycerine, glycerin) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. The glycerol backbone is central to all lipids known as triglycerides. Glycerol is sweet-tasting and of low toxicity. Polymer- is the main building block of all plastics. It is a large molecule (macromolecule) composed of repeating structural units. These sub-units are typically connected by covalent chemical bonds. Although the term polymer is sometimes taken to refer to plastics, it actually encompasses a large class of compounds comprising both natural and synthetic materials with a wide variety of properties. Mucilage- a thick, gluey substance produced by nearly all plants and some microorganisms. It is a polar glycoprotein and an exopolysaccharide. Mucilage in plants plays a role in the storage of water and food, seed germination, and thickening membranes. Starch- or amylum is a carbohydrate consisting of a large number of glucose units joined by glycosidic bonds. This polysaccharide is produced by all green plants as an energy store. It is the most common carbohydrate in the human diet and is contained in large amounts in such staple foods as potatoes, wheat, maize (corn), rice, and cassava. Starch is made of two basic components: amylose and amylopectin. Amylose- is a very long and straight polymer like we want to have in our study. Amylopectin- on the other hand is a branched and short polymer meaning it will yield brittle and weak plastic which is not good. Vinegar- a liquid substance consisting mainly of acetic acid (CH3CO2H) and water, the acetic acid being produced through the fermentation of ethanol by acetic acid bacteria. By adding a small amount of vinegar to the plastic, we can break up some of the branches of the amylopectin which otherwise would make it brittle. Water hyacinth- is a free-floating perennial aquatic plant native to tropical and sub-tropical South America. With broad, thick, glossy, ovate leaves, water hyacinth may rise above the surface of the water as much as 1 meter in height. The leaves are 10–20 cm across, and float above the water surface. They have long, spongy and bulbous stalks. The feathery, freely hanging roots are purple-black. An erect stalk supports a single spike of 8-15 conspicuously attractive flowers, mostly lavender to pink in colour with six petals.
