Shot guns should be banned free essay sample

Guns dont kill people, people kill people. Guns are the only way to protect a civilian from thugs around the world. America is also one of the most dangerous places due to thugs and maï ¬ a gangs who are the criminal minds of murder and shootouts, they have access to any gun you can think of. How would you feel if you got in the way of one of these gangs? you need gun to protect yourself. You wouldnt want to end up dead do you? i strongly believe that all civilians should own a gun in the United states. Since when do criminals obey the law? Banning guns is just taking away Americans rights to defend themselves and their belongings. Banning guns is just opening the door for more shootings as now the criminals will have guns and normal law abiding citizens will be like sitting ducks. In my opinion the only thing that stops a criminal is the thought of the person inside has a gun waiting for me. We will write a custom essay sample on Shot guns should be banned or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The governments should make laws like no one with a mental illness may own a gun, because no one in their right mind is going to go and willingly kill several children. A gun cannot ï ¬ re itself, it has to have someone pull the trigger. If guns are banned criminals will just use other things like knives, pencils, cars and wrenches. Americans have a right to protect themselves with guns. If their Government decides to turn on them, Americans were given the right by the Second Amendment of the Constitution, to have guns for their protection. Taking away guns from everybody in America will not lower any crime rates. Thugs are not going to stop breaking the law regardless of the laws. They will get guns, if guns are banned and then people who need guns for protection have no way to protect themselves. Not only are guns needed for self protection, we use them for hunting as well, if America bans guns, animals like deers, and other wildlife would be over populated and will eventually be living in our community on the roads or even in our backyards, this will cause car accidents and loss of crops due to the animals eating them. I strongly believe that guns should not be banned in the U.S. To conclude guns assure the safety of civillians from danger and also help for hunting purposes. Guns are not the problem to murders, it is the people who pull the trigger, I certainly believe that guns must not be banned in America.

Segregation In Schools essays

Segregation In Schools essays Segregation in the United States, legal or social practice of separating people on the basis of their race or ethnicity. Segregation has been prohibited in the United States since the All over America there seems to be painfully obvious difference in the school systems which cater to the upper class minority and the ones that serve the lower and middle class minority. There is a strong undercurrent of racial inequality in today's school systems, which negatively effect the quality of education that its students receive. A schools potential to give a proper education often depends on the perspective economic, and social, or should I say racial backgrounds of its students. America's school systems seem to be returning to their former state of segregation. The population of minorities who live in theUnited States is constantly increasing and their numbers can contribute to the success or the failure of the nation. Magnet schools, private schools, or suburban schools serve the upper class, minority of the American population. These schools are some of the best high schools in the nation. There are usually a small number of minority children who are lucky enough to attend such quality schools but white children defiantly make up the majority of upper class high In an article that I read from the "National Catholic Reporter" called "A tale of two schools" the author Viebica Stokley discussed the differences between public schools and magnet schools. The magnet school mentioned in the article was called Franklin High. Franklin was a clean, well-lit school. It is air conditioned and freshly painted. There is no graffiti, the bathrooms are clean and there are no roaches or rats present. Franklin has an ample supply of books and supplies. Franklin has a huge library and a computer lab filled with new computers. The school has a TV studio, a new theater, and a school newspaper. Stud...

Music History Essay Example | Topics and Well Written Essays - 250 words

Music History - Essay Example This was not the first effort at change since before the Council of Trent ever convened to discuss music in 1562; the Catholic Church had spoken out against an alleged maltreatment of music used in the mass. In 1503, the manipulation of the beliefs and using non-liturgical songs was looked into. The representatives at the Council were a connection in the long sequence of church clergy who had pressed for a reform of the musical liturgy. The council reforms included prohibiting professional musicians, banishing polyphonic singing and omitting the use of an organ. Council of Trent was attempting to reinstate the sense of holiness to the church setting as well as what was significant for the mass (Fellerer, 1). Pope Marcellus was a forthright critic of excessively overstated polyphony and its disruption from the meaning of the spoken liturgy and the release of holy texts. He made his mass simple in its refined harmonies and not permitting the music to cover the words being sung. By this, he responded to the council of Trent’s concerns. The sections of the Catholic Mass include Kyrie, Gloria, Credo, Sanctus and Angus Dei. It can be sung with influential accompaniment up to and together with a full orchestra or a cappella. The Pope Marcellus Mass was written for six parts a cappella. The parts do not sing the same melody in harmony, thus it is polyphonic. The various voices move separately and at the same time, they form a balanced accord making Palestrina’s mastery of music evident (Josh and Cristi.net,

Reaction to a video Essay Example | Topics and Well Written Essays - 750 words

Reaction to a video - Essay Example Little did I know that in the history of America, a Black adolescent could be shot dead for having whistled to a white woman. Before watching this video, this whole racism thing seemed like a melodrama to me but after having seen this video, things have started to make more sense to me and I can now understand why people take racism so seriously. I had not learned about this before probably because I never understood the importance and gravity of the real issue. Basically there is a whole history, and a very tragic and dark history of America when it comes to the people of color in general and the Black people in particular. It would be totally wrong to suggest that circumstances and conditions for the Black Americans today are the same as they were in the 1950s. However, this does not mean that the radical change in the status and acceptability of the Black Americans in America since 1950s has made the study of such videos irrelevant. I think that this topic should definitely be tau ght in the high schools in America even if racial discrimination is not as apparent in the American society today as it was before so that our children and young generation can really understand the seriousness of the issue like I did after watching this video. ... It breaks my heart to see Emmett Till’s mother narrate the tragic account of his only son’s murder at this age. Especially when she says, â€Å"†¦I saw that his tongue was chopped out. I noticed that the right eye was lying on midway his cheek†¦.† (Mobley). At the same time, I feel proud of that brave and courageous lady for having the guts to show his body as such to the world â€Å"I think everybody needed to know what had happened to Emmett Till† (Mobley). The picture of Emmett Till’s mutilated dead body oozes a very strong message that can shake the foundations of the law-making and law-enforcing agencies and organizations of our country. Unfortunate and tragic events like this should not be forgotten and should always be shown to the young generation to instill hatred for racism in their hearts and to motivate them to behave in a civilized manner in the society. This sad event also has some lessons for the young generation; lesson of bravery can be learned from Willie Reed who stood up against the whole crowd of White men and testified how Emmett Till had been killed. Even though Many Till could not get the justice she was looking for, yet the murder of her only son and the trial and then acquittal of the murderers created such a spur both in the national and in the international sphere, that exposed the racist face of America as well as the lack of justice in American institutions and also became the basis of the Montgomery Bus Boycott, ultimately leading to equality of rights between the Black and White Americans. Racism has lost strength in the roots of the society which it had back in the 1950s, but it has not altogether vanished. Even today, several accounts of racism are witnessed in

Artist statement-lost wax casting Personal Statement

Artist -lost wax casting - Personal Statement Example For a top quality casting, one must use the finest materials in the market (Fred 11). The contrast of the poodle curving determination can be guaranteed by the carver’s skills (Richards 16). The poodles contrast should be appealing to everyone, and so it matters a lot. Careful and skilled curving will enhance the outcomes (Richards 18). The body posture in lost wax casting is supremely crucial because it also what determines of the poodles final looks (Richards 22). This simply means would you like the poodle to be in a standing, or lying flat position (Richards 22). The most challenging part in casting will occur in balancing, especially if the casting of the poodle is to occur in an upright position (Slobodkin 4). The reason behind this is that the feet are the one to hold all the body weight of the poodle reasoning that the feet are smaller compared to the body (Slobodkin 4). The feet base should be flat so as to enhance an upright position of a casted poodle (Slobodkin

Wireless Sensor Networks for Disaster Management

Wireless Sensor Networks for Disaster Management Abstract The world we are living is an event for disasters daily. Some of the disasters are naturally occurring and some occurring due to man-made catastrophes. So not only nature but also human beings are equally responsible for the happenings of these disasters. With the developments in the technologies it is very much possible to find a way to tackle these disasters. Wireless Sensor Networks (WSN) can be used in the developments of disaster management. Hence there is a need for development of a system for the disaster control and management. Also, keeping in mind about developing a structure which is efficient in terms of functioning and the costing. With this paper, we attempt to present some literature study and methodology used by other authors and find the pros and cons in their study. Also, we try to formulate an analysis of the proposed studies. Keywords- Wireless Sensor Networks (WSN), Disaster management. Introduction With the advancements in the WSNs it is possible now to detect and monitor various parameters in our surroundings. The sensors in a networks help us to monitor and keep track on the various paramenters. These parameters include temperature for fire detection, flow mesurement for detection of floods, Global Positioning System (GPS) for location trackink to name a few. With the monitoring of these parameters we can detect any disaster and with the network implementation we can be able broadcast the information. The broadcasting of information would help to reach many people and will alert the people, so that they can move to a safer place. In this paper we will be discussing about the iplementation done in the field of disaster management and would be focussing on the various aspects of the WSNs. The architecture details, componets used, networks used are some of the things to be discussed. Other than WSN, the use of Ad-hoc relay station, mobile communication, base station functions, c ell and cluster functions are also being discussed. The implementation of Wireless Sensor Network (WSN) in a system has been done by many researchers over the years and there are various techniques of implementing them. Development and updating of technologies has made this even more possible. A.S Bhosle et al.[1]ÂÂ   presented classification of various sensors depending upon its function and about the different types of WSN protocols. The network consists of wireless sensor nodes, sink nodes, base stations, a gateway for information transferring, a backbone network and an observer at the output side. The WSN protocols are responsible for the communication between a sensor and the network devices in a network. The sensors can be classified based on their physical properties. These include the flow, positioning, temperature, pressure, acceleration etc. D.V Kishore et al. [2] discussed about the problems of disasters occurring at a mine or excavation location. The main concern in the article was about the blasts occurring in the mi nes and the consequences of that being an increase amount of air pollution, noise pollution and an increase in the chances of accidents in the mine area. They provided a hardware architecture using the traditional electronic components and with the help of that demonstrated the ways of tackling a mishap. S.Saha et al. [3]ÂÂ   proposed an architecture which was based on mobile communication network. The use of mobile communication concepts like cluster, cell, base station and frequency usage was discussed within the architecture. S. Rasaneh et al. [4] proposed an energy resourceful model and implementing the model with an additional communication network would make it more efficient. The model implementation included a hybrid network and a multi hop routing technique for the efficient energy usage. Also, the model implementation included deployment of sensors in various types of environments and depending upon that the sensing operations can be performed. With the use of multi-h op there will be less chances of signal loss or distortions. Thus, in this way the model can become more efficient. S.M. George et al. [5] proposed a Distress network for disaster management and the system architecture consists of 3 components; a Body Net, Sense Net, Vehicle Net Area Net. Body Net is a body worn WSN device which is used to keep a continuous track on the various aspects of a person like heartbeat, blood pressure, location etc. Sense Net is used for sensing the data and is mainly used keeping track of the monitored data. Vehicle Net is responsible for the detection of any disaster is also responsible for the transmission of information. Area Net is used for carrying large volumes of data and as it supports large bandwidth so that helps in sending images, videos and audio data. Kaur, Harminder et al. [6] proposed an architecture consisting of a cluster, an Ad-hoc network, base station, antenna and a satellite. Using these components an efficient disaster can be create d. The architecture works on the principle of multi hopping. After the literature analysis of various articles, we now focus on the methods used in the implementation part of the article. A.S Bhosleet al. [1] in his proposed model demonstrated a disaster about when fire breaks out. Consider in a network, there is a fire exposed area there are more than one sensors to sense the fire, these sensors can for example: thermistor, RTD, thermocouple etc. The wireless sensor node detects the fire and searches for the nearest sink node, then the sink node verifies the collected data with its predefined threshold value. If the threshold value is less than the received data, then a warning signal is send to the end user via base station and the backbone network. If the threshold is greater than received data, then an emergency message is send to the end user via base station and backbone network. D.V Kishore et al. [2] proposed a hardware architecture which had a transmitter and a receiver section. The sensors collected the sensed data as per their prop erty, the various sensors deployed were gas sensor, light sensor, temperature sensor and vibration sensors. The sensed value is converted to digital form by the analogue to digital converter and then is given to the multiplexer, the multiplexer then encodes all the sensed values and sends them to the transmitter and then the transmitter antenna transmits these values to the receiver section. The receiver antenna receives the transmitted values and these values are send to the de-multiplexer. The de-multiplexer then decodes the values and sends them to the microcontroller. The microcontroller then sends the decoded values to the output devices and we can see the output. S.Saha et al. [3] in proposed a heterogenous hybrid model of a network and sensors. The focus was providing a better network coverage and to limit the usage of Ad-hoc relay station (ARS). This was achieved by simply placing the ARS at the edges of the cell and with that the ARS was shared by multiple cells. Sensors no des were placed in a cell to sense various parameters like temperature, vibrations, location, light intensity etc. In a disaster situation, the sensor nodes help in detection of the survivors. After detection, the information is passed to the mobile communication network and the ARS and the base station are responsible for the effective communication between the network.ÂÂ   S. Rasaneh et al. [4] proposed a structure using a simple cluster model of a communication network consisting of sensor nodes, head nodes, second level head nodes and base station. The sensor nodes are used to sense different functions accordingly; these are seismic vibrations for earthquake, temperature for fire, flow measurement for floods, weather sensors for humidity etc. In a disaster situation, the sensor nodes in a cluster firstly sense the various parameters as per their individual sensor properties and then send the collected data to the second level cluster head and then a cluster head receives al l the data from other second level cluster heads from every cluster. Then, the base station receives all the data from the cluster heads. The data is send from a second level cluster to the cluster head to have an efficient data flow without any signal losses. This structure uses the multi-hop technique so that data can transmission can be done efficiently. Kaur, Harminer et al. [6] proposed an architecture involving usage of a mobile network, radio and satellite communication. During any disaster, the sink nodes collects data from the local sensors and ARS. The data is then collected by the base station with the help of the sink nodes in the network. The base station sends the data to the antenna and the antenna broadcasts the signals to the satellite. The satellite then sends the warning about the disaster to the local hospitals and the ambulance. There are various gaps in the above discussed articles. We cannot be relying on an architecture that is a hardware based as within any kind of disaster it cannot be accurate and depending upon the intensity and how powerful the disaster is the hardware with not withstand and would surely be damaged. Also about the deployment of ARS in the edges of cell, then the signal handling capacity of the ARS gets affected and this produces latency in the network. This affects the performance of the architecture. In the fire disaster system, the distance between the cluster and the operating network is very large and if there is any latency introduced in the network, then it would be very late for the signaling about the disaster. With the developments in the field of Wireless Sensor networks we can surely be opting on trying and formulating new ways to find solution to these problems. Also with the ongoing problems in terms of disasters there is a need to do to. After the study, there are still many developments that can be done in many aspects of the architecture, technology used and the components used. The focus must be on trying new developments and if possible go to find the solutions of the current problems related with the disaster management. WSN can help in predetermining of the any disaster and we can then alert everybody about it. References [1]A. S. Bhosle and L. M.

The main argument behind such a direction is that art students will be thus equipped with prerequisite science skills, which they can then apply in their field. However, such an argument has not considered the incorporation of science units in most of the arts programs, which on their own, can help to equip art students with basic skills like statistics, computer studies, and the use of the internet. A number of issues that influence the intention and the process of learning should be considered on the subject abo... ...vels of innovation in science and arts will be required. Therefore, the challenge is for our colleges to produce educated personalities that will help in tackling the many challenges that will always be present in our society. To some extent, education is not about taking up multiple courses, and obtaining high grades. Rather, education is more about equipping yourself with interesting, challenging, and inquisitive knowledge. A meaningful process of education can hardly exist in an environment that is devoid of freedom and interest to someone. Such a truth needs to be considered when debating on the issues that I have discussed above. As I have presented here, it is useful that art students are not compelled to undertake science courses. Such a direction is important in enhancing the capacity of students to enjoy, and therefore, fruitfully participate in learning.

Producing Isoamyl Acetate from Isoamy

This was then weighed and computed for the percent lied. The theoretical yield and the weighed value must have close values in order for this experiment to be successful. Keywords: fruit flavors, banana flavor, call stratification, reflux, extraction, washing, drying, drying agents Introduction Esters are a group of organic compounds that give out distinct odors. Examples of esters are fruit flavors such as the product of this experiment. Somali acetate or banana flavor is an ester which resulted from an call stratification between Somali alcohol and Acetic anhydride.Call stratification is a reaction between acid anhydride and call chlorides. Through this experiment, the students that performed It would have learned about reflux, extraction, washing and drying. The reflux technique is the boiling of the reagents while cooling the vapor escaping from it and having it returned in the flask to prevent evaporation. This guarantees that the temperature in the flask is constant. Extraction , washing and drying the resulting chemicals after the reflux technique separates the desired product, in this experiment It was the Somali acetate, from the excess products.Drying agents are used twice In this experiment, first to remove the water where the undesired reduces was washed Into and the last to remove the excess. The objectives of this experiment is as follows: To synthesize Somali acetate from Somali alcohol and Acetic anhydride To calculate percent yield of Somali acetate To learn the reflux technique To learn the technique of extraction, washing and drying Methodology First, the reagents were prepared and properly labeled. 5 drops of concentrated HOSTS was added into the acetic anhydride while in an ice bath.While still in the ice bath, Somali alcohol was slowly added into the acetic anhydride. The reaction was extremely exothermic which explains the use of an ice bath. See Figure 1) The reagents were then transferred into a reaction flask. Three boiling chips were a dded in order for the chemicals to boil easily. It was then refluxed for 30 minutes making sure that the temperature remains constant at ICC. (See Figure 2) It is necessary to keep the temperature constant in order to avoid explosions. Figure 2.Reflux Technique It was then poured into a beaker with crushed ice and allowed to melt. After melting, it was transferred into a separating funnel. 15 ml saturated Enhance was added into the solution. This was necessary in order for the organic components to react with it ND become water-soluble. The funnel was then swirled until two layers have separated. (See Figure 3) Figure 3. Swirling the Separating Funnel The lower layer was discarded and 15 ml of saturated NCAA was added. NCAA was a drying agent for the removal of water.

Free Essays on The Meaning Of Greatness

Greatness can de defined in many ways, however to be truly great you simply need acceptance. Bernard Malamud’s main character in The Assistant Morris Bober exemplifies this humble greatness while refuting mislead ideals of pompous greatness. Camus’ The Myth of Sisyphus mirrors Morris’ ideal of greatness through the silent acceptance of one’s destiny. Morris lives a very simple, bleak like. He gets up at the same time every morning, sells the same products to the same customers, takes the same breaks, does the same chores, worries about the same bills from the same store and his family every single day. Nothing has changed much. However despondent a life Morris lives however, he never fails to help out those who are worse off than him. â€Å"He found a penciled spot on the worn counter, near the cash register, and wrote the sum under ’Drunk Womnen’. The new total now came to $2.03†¦Ã¢â‚¬  ( Malamud, 2). Even when Frank confesses to holding Morris up, he reveals that, â€Å"This I already know, you don’t tell me nothing new.† (Malamud, 188). Morris found his greatness through his acceptance of his humble life much like Sisyphus from Camus’ The Myth of Sisy phus. â€Å"At each of those moments when he leaves the heights and gradually sinks toward the lairs of the gods, he is superior to his fate. He is stronger than his rock.†(Camus, 230). Only through accepting one’s fate humbly with understanding like Morris and Sisyphus can one become â€Å"stronger than his rock†. It is evident in Morris’ demeanor that not only does he hold Camus’ ideals among greatness, but that he openly refutes Carlye’s ideals as well.

Compare and Contrast two different architectural structures that have Essay

Compare and Contrast two different architectural structures that have similarities and differences - Essay Example The dome covers the 3025 m2 of the base and has a height of around 35 meters. The dome is decorated with tall spires and lotus design providing a blend of Persian architecture with Hindustani decorative element (DuTemple).i The spheres of the Sydney Opera House which form the roof of the structure are the most extravagant attribute of the building. The spheres depict the earliest advancements in structural engineering as the irregular shape of each sphere was subjected to numerous asymmetrical forces (Shofner). The amazing appearance of the spheres was achieved by covering them with glossy white and matte-cream colored tiles imported from Sweden. ii Although there is an evident difference between the ways the two structures appear, but the roof designs in the form of domes and spheres have marked similarities as well; both the structures have curved roofs with a pleasant white appearance. The marble domes of Taj Mahal were constructed using the traditional Mughal construction technique with massive brick scaffolding, whereas precast concrete members were used to construct the spheres of Opera House. The exterior and much of the interior of Taj Mahal has been decorated with gemstones embedded in bronze. Large calligraphy panelsiii run from ground up to the arches and Islamic calligraphic inscriptions have been manually inscribed on the stone panels with astonishing precision.iv The magnificent arches and the intricate jalis are the other outstanding features of the interior.v Interior of Taj Mahal is an exemplary piece of work of Mughal architecture, similarly the interior of Sydney Opera House with its plain and topaz tinted glass, birch plywood and aluminum panelsvi is a perfect depiction of modern architecture in which prime importance is given to the function of the building (Murray). Wood cladding has been used in much of the interior of the Opera House in order to

Study Skills Essay Example | Topics and Well Written Essays - 1000 words

Study Skills - Essay Example With such an attitude, you can never achieve anything since you will feel that you are studying just to please someone else. Freeman (2002, p.44) suggests that the first thing you should instill within yourself is a positive attitude towards studying by setting your study goals, and developing appropriate means on how to achieve them. When I joined this institution as a first year student, I can confess that I too had a negative attitude towards studies because, I hated the act of going to class, listening to a lecturer, and then exams (Jones, 2003, p.102). I thought that if we only came to school to spend our time with friends and sharing our life experiences, then all could have been well. Unfortunately, the thought of exams and assessment tests really upset me. I already had developed a negative attitude as I attended lectures to wait for the lecturer to do his part, without even caring about what I had gained from the lecture. I rarely carried out my own research unless when orde red by a lecturer to do so. Moreover, I only studied for exams through cramming after which everything was gone and forgotten (Armstrong & Lampe, 2000, p. 64). Little did I know that school was preparing us for the challenging life out there, and it is meant for our own good. The education and training I have been exposed to in this institution has really changed my attitude as well as my perception towards studying. First, here you are introduced to an environment of freedom where you are expected to be responsible for your own actions (Freeman, 2002, p.44). At first, I felt that it was the best feeling ever since I was now of age and my parents/teachers had no full control over my life. I thought that life had presented to me a perfect opportunity to do all the craziest stuff I have been longing for in my life. Fortunately, with the endless words of advice from my lecturers and parents, I have learnt that society expects us to be morally and socially responsible individuals. I hav e been taught how to communicate, interact and live with other people effectively without any form of conflict among us. Furthermore, I have widened my knowledge and skills through the technical skills I have gained, to ensure that I will cope well with working in the real field out there (Jones, 2003, p.142). Whichever way you may look at it, it all streams to one thing; when my effort is demanded rather than required, I will struggle through to see that I have provided it no matter how I feel (Armstrong & Lampe, 2000, p. 88). This can looked at as an effort of trying to get things done, and it might not be the best way of doing things. I have learnt that the key thing into getting things done without much effort and struggle is motivation. Through motivation, everything you engage in will be enjoyable as you are likely to gain some satisfaction upon accomplishing it. However, before you get motivated you have to find your purpose in life. As a student my ambition is to be a great person in the future who the young generation will strive to emulate. Freeman (2002, p.67) asserts that this calls for a proper setting of priorities right from this moment. I have to know that I study to acquire more knowledge and skills so as to know how to face challenging situations that come my way, but not just for exams. I can clearly admit that personal
