Working with algebra free essay sample

Working with algebra you must understand why the properties of real numbers are so important. I will demonstrate my solutions to three problems and I will include my mathematical work. Also I will use five vocabulary words that help me find solutions to the problems. Properties of real numbers are useful for simplifying algebraic expression because a lot of thing we do in life are equations. We use a lot of mathematical terms in the real world. Lastly I will show every step I took to simplify and identify each property of real numbers. The properties of algebra are important to know and understand. â€Å"Algebra is useful because it can be used to solve problems. Since problems are often communicated verbally, we must be able to translate verbal expressions into algebraic expressions and translate algebraic expressions into verbal expressions. † (Dugopolski, 2012, Chapter 1. 6, ) Each expression has properties that must be simplified and solving methods. We will write a custom essay sample on Working with algebra or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page You have to know how to follow the order of operation and simplify the equations, variables and like terms in order to complete the mathematical work. Simplify is very important in all expression, must be in simplest form when completely an equations. Also you have to move and combine like terms. The coefficient of a number is in front of a variable. The coefficient is a factor that can produce a result. The distributive property is a step that multiples a term to be followed in order for the equation to be complete. Lastly removing parentheses is another step you should follow in any equations or expression. You must remove the parentheses in order to solve the equation. I will now demonstrate how the properties of real numbers are used while I simplify the following expressions. 2a (a – 5) + 4(a – 5) 2a2-10a+4a-20 2a2-6a-20 The given expression I multiply by distributive property and that allowed me to remove the parentheses. Then I combined the like terms by adding the coefficients. The distributive property removes the parentheses. I did not have change any order of operations the like term was already together in the middle of the expression. 2w – 3 + 3(w – 4) – 5(w – 6) 2w – 3 + 3w -12 – 5w +30 2w +3w -5w -3 -12 +30 w +15 With this given expression I had to distribute the property in order to remove the parentheses. I move the like terms so they can be arrange together using the commutative property to switch their places. Also two of the variable terms are added and two of the constant terms are also added. I then added the like terms and now this expression is simplified. 0. 05(0. 3m + 35n) – 0. 8(-0. 09n – 22m) 0. 015m + 1. 75n + 0. 072n + 17. 6m 0. 015m + 17. 6m + 1. 75n + 0. 072n 17. 615m +1. 822n With this given expression I had to distribute the properties and remove the parentheses. I arrange the like terms and then combined them together using the commutative property. The like terms was combined by adding the coefficients. I had to be careful with this expression because of the decimals. I still followed the same steps as before in the other expression. â€Å"Algebraic expressions are used to describe or model real-life situations. †( Dugopolski, 2012, Chapter 1. 6, ) I learned that algebraic expressions can be used to solve a real life problem. It’s just like going to the store and you need to sum, or the difference, or percentage of an item. I realize you use algebraic expression very often in everyday life. I was able to describe step by step of what I had to do in order to solve the expression. I also touch base with my vocabulary words by using them in my explanation of how to solve the expression.

The field of psychology

The field of psychology may have grown to be respected as a science. Objectivity and the scientific method are both part of the psychologist's mode of operation. However, even the greatest of psychologists can only theorize about what makes human beings act the way they do. Absolutes are not part of psychology . Everything is relative and open to speculation. Theorists give us their views or ideas about life. In the field of psychology, there have been many different areas of interest. Human development is one of the most popular areas of interest for those who study psychology. Freud, Erikson and Piaget are all great theorists with different ideas concerning human development. Each theorist developed ideas and stages for human development. Their theories on human development had human beings passing through different stages. Each theory differed on what these stages were. These theories also differed with their respect towards paradigmatic assumptions, learning and development, and relationship towards educational practice. Freud is known as the father of psychology. Although some of his work has been dismissed, most of it still holds weight in the world of psychology. Freud believed that human development was fueled by inner forces. He believed the most powerful of all inner forces was our sexual being. Freud linked everything with sex. This includes any bodily pleasure whatsoever. Thus, when Freud discusses the sexual needs of children, they are not the same kind of sexual needs that an adult would experience. Children experienced sexual gratification in different ways. Sucking their thumbs or retaining their excrement could be seen as sexual gratification for small children. Freud also specified certain areas of our body as erogenous zones. Those areas included the mouth and genitals. This all fit in to Freud's obsession with sex. An obsession that could be linked to the era that Freud lived in. It was a very conservative per...

D2 - Assignment Example In cases where the number ‘10’ acts as the base for common logarithms, e serves the same purpose for natural logarithms. In mathematical terms, where n tends to infinity, e is the limit. The approximation of e provided by Euler was up to eighteen decimal places. However, its numerical value goes beyond those eighteen decimal places. The common aspect of arithmetic and geometric sequences is that there is always a common constant or ratio between any two consecutive terms of the sequences. For example, in case of arithmetic sequence, if the constant of difference between a term and its preceding term is 4, it will be 4 for the whole sequence. Similarly, in case of geometric sequence, if the ratio of difference between a term and its preceding term is 2, it will be 2 for the whole sequence. The difference between arithmetic and geometric sequences is that in an arithmetic sequence, a specific constant is the difference between any term and its preceding term. On the other hand, in case of a geometric sequence, there is always a specific ratio between any term and its preceding

Train Wreck and Cholorine spill Case Study Example | Topics and Well Written Essays - 1250 words

Train Wreck and Cholorine spill - Case Study Example The tragic accident caused the death of nine people and displaced more than 5,000 from their residences, thus permanently altering the community. Although the eventual death toll was surprisingly low, the study shows that locals’ response to the emergency situation had significant gaps and it also emphasizes on the need to transform major organizations’ practices especially in handling hazardous materials. This case study, therefore, seeks to evaluate decision making processes in regard to no-notice evacuation during emergency situations, as well as, determining long-term effects of the chlorine disaster on organizations dealing with transportation. Overall, the case study attempts to highlight the necessity for improvement of evacuation procedures and recovery of transportation (Dunning & Oswalt, 2009). There are several specific issues emerging from the chlorine spill case study. For instance, operation concepts of rail transportation emerged, like the importance of keen train control, as well as, installation of automated warning technologies. The other outstanding issue in the study was the local community’s lack of information about emergency procedures to adopt in case of a chlorine spill, despite the fact that the hazardous material was transported across the town each day. The public’s need for transportation to their jobs following the evacuation was also a principal concern and so was provision of documents about transportation infrastructure, in order to foster recovery. Overall, evacuation concerns were the most outstanding in this case. For instance, locals did not know whether to seek shelter or completely leave the town, they also had no information about the safest routes to follow, or the best way to behave and collaborate with emergency workers, in or der to avoid being affected by the hazardous material. The

What could happen if computers substituted human thinking Research Paper

What could happen if computers substituted human thinking - Research Paper Example Understanding and thinking is the route to develop curiosity in every human being which enables them to explore, learn and interact with the surrounding. Accordng to Walter (2008), we have a network of relationships in our mind (Preface, p. XIII). The conceived thought can be used either in a constructive manner or destructive manner. Human thinking skills have developed innovative technologies over the years. In modern civilized society, in many households we are using automatic dishwashers, riding lawnmowers, T.V. remote controls, automatic garage door openers, power screwdrivers, bread machines, electric pencil sharpeners, etc., etc. etc. Humans have created computers to facilitate this easy and comfortable life. Unfortunately this trend in workplaces and living areas is taking our lives into pitfalls by making us lethargic and passive. We are going against our health that too, without much realization. Overuse and overview of these items restricting our diverse physical movements, and still we are calling it as a wonderful life. Irony is that, do we really want our life to be dull, lazy with all ill health effects If we let these technologies take over us, it might happen that over the time we could become slaves of the technology. Computerization is facing criticism due to its unparalleled powers to harm life for all future generations. An unknown new way gives rise to whole set of new questions. These problems might be such that we would have never thought of. The consequences of the substitution of human thinking by computers might entail unprecedented risks to human health and the environment. The mental ability of human being is irreplaceable by any artificially created intelligence which is not self supportive. Computers are created and used to carry out number of predefined activities in an orderly fashion (Walter, 2008). They are programmed according to human intellect and translate the commands in a sequential fashion without knowing the end

An Analysis of Eliots Adam Bede

An Analysis of Eliots Adam Bede â€Å"Adam Bede†- George Eliot Summary: Dinah Morris is a Methodist preacher who arrives in Hayslope, a small village in England, during the late 18th century (1799). Dinah resides with her aunt and uncle named Mr. and Mrs. Poyser, however, she hopes to return to where she normally lives in Snowfield. Seth Bede, who is a local carpenter, loves Dinah and is still adjusting to her rejection of his marriage proposal. Seth’s brother, Adam Bede, also resides in Hayslope and works as the foreman at the local carpentry shop where he and his brother both work. Adam is smitten with a young girl of seventeen named Hetty Sorrel who lives in the village. Hetty is Mr. Poyser’s niece and lives with the Poysers’ where she helps with the chores. Thias Bede is the father of Seth and Adam. He drowns in the river near their house after he had gone on a drinking binge. Seth and Adam’s mother, Lisbeth, is distraught by this and so Dinah goes to comfort Lisbeth where she is able to soothe her where no one else can. Lisbeth also wishes for Dinah to become her daughter-in-law. Squire Donnithorne is the local landlord who governs the parish very strictly. His grandson and heir, Captain Donnithorne is a member of the regimental army and lives with the Squire. The local villagers all respect and adore Captain Donnithorne, who considers himself a man of great chivalry. Captain Donnithorne flirts secretively with Hetty after first meeting her at the Poyser’s residence. He asks Hetty when she will be visiting the Squire’s residence again and arranges to meet her unaccompanied in the woods when she passes through. When Captain Donnithorne meets up with Hetty in the woods this is the first time that they have been alone and are both bashful. Captain Donnithorne teases Hetty about her many suitors which makes her cry. He then puts his arms around her to comfort her but then he immediately panics at the inappropriateness of his advances and leaves Hetty alone in the woods. Later Captain Donnithorne meditates on what he has done and resolves that he needs to approach Hetty as to clear up what had happened. He meets her on her way back through the woods where they kiss. This encounter marks the beginning of a summer-long affair which ends when Captain Donnithorne leaves to rejoin his regiment once again. Hetty believes that Captain Donnithorne will join in matrimony and that he will make her into the great socialite she dreams of being. Although Hetty does not exactly love him she loves the wealth and privilege that he represents. Captain Donnithorne hosts a party for himself to which he invites all the members in the parish. Everyone attends and has a wonderful time with a feast, dancing and games that were provided. Adam notices that Hetty is wearing a locket that Captain Donnithorne had given her and becomes suspicious that she might have a secret lover, however, he concludes that it would not be possible for her to conceal such a thing from the Poysers. On the last night that Captain Donnithorne is in town, Adam surprises the guilty pair in the woods and forces Arthur to fight, Adam wins this fight. Captain Donnithorne lied to Adam and said that the affair was no more than a little flirtation. Adam responded by telling him that he must write a letter to Hetty letting her know that the affair is over. Captain Donnithorne obeys Adam and Adam delivers the letter. Hetty is heart broken by this news but after some time she resolves to marry Adam as a way out of her current life. When Adam proposed Hetty accepted. When Captain Donnithorne is due for departure, Hetty is pregnant, unknown to either of them. She resolves to go out and find Captain Donnithorne because she cannot tolerate to have those who know her discover her shame. She believes that Captain Donnithorne will help her even though she senses that he can never remove her shame. Hetty sets out to find Captain Donnithorne and at the end of an arduous journey Hetty learns that he has gone to Ireland. She then decides to head in the direction of home with the intention of visiting Dinah, who Hetty believes will help her without judging her. During this trip Dinah gives birth to her child. Distraught by this she takes the child into the woods and buries it under a tree. Hetty leaves the child there but she cannot escape the sound of the child’s cry. She returns to where she left the baby where a farm laborer and the Stoniton constable discover her and the take her into custody for the murder of her child. Adam is distraught when he cannot find Hetty and concludes that Captain Donnithorne must have lured her away from their impending marriage. Before traveling to Ireland to find him Adam goes to Mr. Irwine to tell him of his plan. Mr. Irwine tells Adam that Hetty is in jail for murder. Even though the situation distresses him Adam attends her trial. Dinah arrives and is able to convince Hetty that she must repent to save her soul. Hetty is then convicted and sentenced to die. At the last possible moment Captain Donnithorne arrives with a stay of execution. Hetty is sent away from England for her crimes and dies just before she is set to return to Hayslope. Captain Donnithorne leaves for a while because of the shame he has brought upon the Poysers’ and also Adam. Adam recognizes that he is in love with Dinah so he proposes to her but she rejects him until she comes to realize that it is God’s will that she marry Adam. They are married and have two children. Seth lives with them and does not marry. Captain Donnithorne eventually returns to Hayslope where he and Adam meet one last time at the conclusion of the novel. They are both able to stay friends despite all that has come between them. Narrative style: The narrator speaks primarily in the third person, centering on characters one at a time and revealing their thoughts and feelings in turn. At times the narrator breaks through to comment on the actions and feelings of the character in the first person. The narrator in Adam Bede butts into the story to offer ironic and often sarcastic commentary on the characters and the reader’s impression of them by the use of satire. The satire keeps the narrative sharp and the tone light. The narrator uses humor where a big part of that humor is in the sarcasm. Character analysis: Adam Bede- An intelligent and fairly well educated man for a peasant. He is industrious and loyal, as well as kind-hearted and a man of good morals and values. Adam is multi-faceted because his character develops throughout the novel. In the beginning Adam is a proud man and is judgmental, especially towards his father and his situation, however, at the end of the novel Adam’s pride is largely humbled and he is less judgmental towards others because of Hetty’s crimes where he is mellowed by the experience. Dinah Morris- A Methodist preacher who seeks to bring God’s love to all those around her. Dinah’s gentle manner and selflessness bring comfort to others. She is a woman of simplicity who lives to help others. Dinah is multifaceted because her character develops throughout the novel. In the beginning she feels compelled to help those in greatest need even when it results in the denial of her own happiness but eventually she comes to believe that her own happiness and God’s Will are not necessarily incompatible when she falls in love with Adam and marries him. Language and diction: Eliot’s language and diction that he uses is befitting of the time period in which this novel was written (late 1850s) and so the language is very formal and polished with a refined tone. Extensive descriptions are followed by dialogue. The descriptions set the scene to which the characters are subject to and the dialogue follows by elaborating on what is happening in the description. Vast uses of figures of speech assist the descriptions in being successful. The dialogue allows for the reader to get to know the characters better and to understand the relationships between one another. Imagery: By the extensive use of adjectives and figures of speech all the senses were met. Eliot describes the countryside effectively with a predominant use of such metaphors and personification in: â€Å"High up against the horizon were the huge conical masses of hill, like giant mounds intended to fortify this region of corn and grass against the keen and hungry winds of the north†, here my sense of sight was met most. I was also able to hear the sounds of Chad â€Å"beating the stick against the milk can by way of musical accompaniment† that appealed to my sense of hearing. The sense of touch was achieved when Mr Irwine went to Anne’s bedside and kissed her â€Å"delicate hands† to which he felt the â€Å"slight pressure from the small fingers†. Eliot uses â€Å"Fresh fragrance of new-pressed cheese, of firm butter, of wooden vessels perpetually bathed in pure water† to achieve the sense of smell as he describes the hot and dusty streets. Whilst t he Bede family and Dinah were in the kitchen having breakfast: â€Å"warm porridge and toasted oat-cake† appealed to my sense of taste as I could feel my mouth watering for the scrumptious breakfast about to be devoured. The most evident sense in Adam Bede, like most novels, was the sense of sight, however, all my senses where felt in this novel which made it a sensual experience. Themes: Inner and outer beauty Eliot contrasts inner and outer beauty throughout the novel to express the idea that external and internal authenticities do not always correspond. Although Hetty is more physically attractive than Dinah she is cold and ugly inside- this is the opposite of Dinah. Dinah’s inner beauty matches that of Hetty’s outer beauty. Hetty’s outer beauty masks her inner unattractiveness, especially to Captain Donnithorne and Adam. Even when Hetty cries or is angry she continues to appear as being charming to both men. Adam is blinded by Hetty’s appearance which causes him to misinterpret her tears and delight as love for him. Hetty’s outer beauty also blinds and shades Captain Donnithorne judgement such that he loses control when she cries and thus kisses her. Unlike Hetty, Dinah has a deep inner beauty because she helps and cares for those around her. Dinah comforts Lisbeth through the mourning of her deceased husband. Adam does not thin k Dinah is as physically attractive as Hetty but he is drawn to her love and mission to aid the people surrounding her. His feelings for Dinah change after he witnesses Dinah consoling Hetty as he begins to realize that Dinah is outwardly beautiful. The consequences of bad behavior- Bad behavior and misconduct have consequences that extend far beyond the person doing wrong and even relatively small transgressions can have considerable collateral effects, this is seen in Adam Bede. The fundamental lesson from Hetty’s experience with Captain Donnithorne is that doing the right thing is more important because doing the wrong thing may hurt others in ways that cannot be controlled and measured. Although Captain Donnithorne is not inherently wicked he provokes bad behavior in Hetty because he does not make himself available to her when she seeks for his help once she learns that she is pregnant. Hetty is ashamed and selfish when she commits her crime. As Hetty awaits the trial, she does not think about how her bad behavior has affected anyone else as she does not consider the shame she has brought upon the Poysers’ or the effect that her crime has on Adam. Hetty feels no remorse for her sins and only wishes to not be re minded of any wrong she has done. In the end she apologizes to Adam and asks God for forgiveness but the moral of the story is that actions of bad behavior, evil, and wrongdoing cannot be undone or changed. Setting: The novel is set in a small village in England called Hayslope which is quaint and reflects the character of Hetty in the beginning of the novel as well as all the innocence in the other characters. The setting is cyclic which represents the life of the villagers as they do their day to day errands. The fact that the setting is a small village assists in also creating a sense of loneliness, which is something experienced by Hetty later on in the novel. The village setting is therefore accompanied by more forests and vegetation than the large city. Nature is seen to play a role in romance and love, in Hayslope there is this nature setting which accompanies and facilitates various forms of love in the novel. Genre: This novel is a fictional novel because the plot did not actually take place but was rather formulated from Eliot’s imagination. Adam Bede is also a romantic drama: the romance is seen between the webbed relationships of Adam Hetty, Hetty Arthur and Dinah Adam. The drama is portrayed in the actions of the characters: Lisabeth’s husband dying, Hetty and Arthur’s flirtation whilst Adam had proposed to her previously, Hetty’s pregnancy and how she dealt with it (killing her baby) and eventually the concluding matrimony of Dinah and Adam. The drama is seen through such trials and tribulations in the novel. Aspects I liked: For a novel of this time which was first published in 1859 I did not expect such a dramatic storyline with a drastic twist towards the end where Hetty murdered her baby, however, it was refreshing and something new, I enjoyed this aspect because one can truly never judge a book by its cover. I enjoyed the extensive descriptions of Eliot’s, however, at times it can be overpowering in the sense that it is unnecessarily long. The enjoyment of these descriptions comes from the vast use of figures of speech used by Eliot. I have not read a novel that uses as many figures of speech and so this was interesting for me. The dialogue which usually followed the descriptions was also thorough in that there was a lot of dialogue. This enabled me to understand the characters better and their relationships with one another, which in turn made me understand and follow the plot better. Recommendations: I would recommend this novel to people who are not lazy readers and those who enjoy thorough descriptions in novels. This novel would also appeal to people who do not enjoy novels with a ‘typical’ storyline as it contains a twist due to bad decisions. I would recommend this novel because of the moral of the story which is relevant in our day and age: bad behavior has consequences so think twice before taking action. I would not recommend this novel to people who are sensitive about religion as this novel speaks about this in its dialogue quite often and to people who do not enjoy dramatic novels.

A Defining Moment with Dad :: Personal Narrative Profile

A Defining Moment with Dad    My father is a gentle and polite person with an impressive career and decorated sporting background. However, he has had to endure a form of early onset dementia for well over a decade. His prime caregiver is my mother, who we believe has managed to slow my father's deterioration by keeping him mentally stimulated with a pre-arranged activity every day of the week. Of course, this strategy also cares for my mother, as it gives here peace of mind that my father has a reason to get up each day. Just as importantly, it buys her valuable personal time to do something for herself.    But each time the deterioration reveals another unexpected issue to face, my mother's determination becomes threatened, and needs it own caring. The most significant and recent issue was when my father began experiencing a mild form of alcohol abuse and associated deviant behavior. After a difficult but seemingly successful battle, my mother recognized that she needed a break. I took a week off from my life and took over the caring role at our vacation home.    Apart from wanting to help my mother, I also took on the role in the hope that my father and I could share a moment that bonded us. I would build him a wood shed that would help him with his continuing sense of responsibility to cut and store firewood. In 'true-blue' father and son style, our joint work would create a bond that opened a moment of reflection that I could treasure forever.   Well, we did occasionally work together, but dad's attention and physical ability wavered, and after a few minutes I would find him returning to his sun couch or sitting inside staring into space. Maybe there were moments where I felt a subtle bond, but I soon realized that my expectations were unrealistic.    Meanwhile, I cooked, cleaned and answered hundreds of questions such as 'where does this go', 'will I take the rubbish out' and 'when did you say you were leaving?' Each day I saw every channel of television news viewed back to back. I realized that without a reminder the same pair of underpants can be worn an infinite number of times, and that best clothes can be worn to mow the lawn and clothes covered in stains can be worn out to dinner.

Gender Stereotyping In The Media Essay

It has been strongly evident that the media has played a large role in gender stereotyping for decades. Since the very beginning of film, movies and television shows have depicted men and especially women as lower or lesser beings. This â€Å"tradition† of sexism has of course, decreased since the 50’s but still lingers on in many of today’s television programs. In the early 50’s, with television shows such as â€Å"I Dream of Jeanie† and â€Å"I Love Lucy, women were portrayed quite openly as being the server to their husbands, the men. They were considered to be lower than men or in other words of less importance. Many of the shows from this era showed a substantial amount of gender stereotyping. For example, the women were to do what they were told, they were the only ones who cooked and cleaned, and they were the primary caregiver for the children. Of course, things have changed since the 50’s. Women have proven to be powerful and just as competent as men, thus, making it harder for television shows to portray them as lesser individuals. However, although the gender stereotyping has decreased, it is certainly still evident in the media. There are several television shows being broadcasted today that do, in fact, show some form of gender stereotyping, particularly towards women. However, it is less out in the open and blunt than it use to be in the early 50’s and 60’s. One must read between the lines and pay attention to notice the stereotypic behavior being portrayed. While this behavior may be subtle, it does, in fact still exist. There is a very well known show on MTV known as â€Å"The Real World,† which comes on every Wednesday. It is a reality based show which places seven strangers into one house for several weeks where they are to live together for the duration of the program. As many of us know, reality shows are not what they appear to be. The directors and producers of such shows have the ability to crop and edit which specific clips of the film that they want to be premiered. Inevitably, they are able to portray the individuals on their show in any way that they want. For example, they may choose to only show clips of certain individuals where they are crying, fighting, or as â€Å"The Real World† often does, being promiscuous. This is a vital key in how this show can stereotype a specific gender. In episode three of the new and current season of â€Å"The Real World,† it can be concluded that women are overall depicted as foolish, whiney, selfish, rude, childish, and promiscuous. The men of the serious, however, are showed in a softer, lighter side. They are portrayed as caring individuals who would rather stay away from most of the women and stray from any drama or arguments going on inside of the house. In one segment of the show, two of the women of the house are running around the house screaming and yelling, playing a game which appears to be cowboys and Indians. The next scene shows the men of the house calmly sitting outside having adult conversations. This is clearly in effort to make the females look childish. In another segment of the show, the women are basically all fighting with one another while the men sit quietly in the background. One of the females sarcastically asks another cast member if it is fun living with a bunch of girls. The other cast member quickly responds with a no. It should be understood that not everything that the women in the house on this show have done have been childish or in anyway degrading. It is impossible to fit everything that has been recorded of these people when producing the show. So, everything that viewers are allowed to see has been carefully selected for various reasons such as higher ratings. The more dramatic events that happen, the more likely it will be for the show to attract audiences. However, why is it that there are no dramatic sequences shown where the men are degrading themselves? In conclusion, gender stereotyping in the media, although lessened since the 50’s, does still exist on television programs today. Whether women are portrayed as inferior to men or simply more ignorant or immature, the fact is that gender stereotyping is an all too sad reality in the world that we live in today. Perhaps one day we can come to an understanding that all men AND women and created equally. Works Cited www. mtv. com www. realworld. com www. people. unt. edu/jw0109/misc/stereotype. htm

Revolution in Cairo

Revolution in Cairo The PBS documentary titled Cairo Revolution is about the response of ordinary Egyptians on Mubarak’s oppressive government leadership. It is about non elitists who grew increasingly discontent with the happenings in Cairo. It is about ordinary citizens who could not continue to watch the heightening levels of corruption and injustice.Advertising We will write a custom critical writing sample on Revolution in Cairo specifically for you for only $16.05 $11/page Learn More The revolution followed several years of repression in Egypt. Youthful Egyptians got tired of the rising police brutality and interrogative torture upon the citizens. Other issues including election rigging and refusal to hand over power by the Mubarak regime fueled the protest. The young people constituting of not less than 60% of the population became tired of the rising unemployment rates. Many of the Egyptian youth became unemployed despite having university education. The people w anted change and would do anything to see that change. A group of young people led by a technology savvy civil engineer formed a movement – the April 6 youth movement. The movement started campaigning in 2008. They organized a peaceful protest against the injustices experienced by textile workers. The success of that protest led to the formalization of the movement with a mission to organize and mobilize ordinary people to fight for their rights. It took three years to regroup, strategize, coin the movement’s agenda and launch out. They demanded that Mubarak and his children should never run during presidential elections. They called for immediate dissolution of the national assembly and a repealing of the emergency law. Other issues included reformation on the constitution and government policies. The movement was out to denounce corrupt leaders and bring a lasting change to the unemployment problems of the youth. They wanted to see Egypt freed from police brutality. The revolt became a massive success. Organizing for a revolution is not an easy task. The difficulties to be dealt with became enormous. The government was not ready for any anti government protests and would use government tools to deal with any assertions against the regime. The youth movement got into planning despite the government’s opposition. The movement had obvious strength that the government did not know. The strategy included the use of cyber space – internet to spread the planned revolt. The leaders of the youth movement used social media channels including face book, twitter and blogging to mobilize the youth and further their anti government slogans.Advertising Looking for critical writing on political sciences?

Other means of communication included the use of cell phones to se nd short messages that the youth forwarded to all the contacts on their cell phones. The movement also spent quality time together studying the works of Nelson Mandela and the student led resistant in Serbia. One of the key leaders of the April 6 movement went to Serbia to learn the art of non violent protests. He learnt how to teach others to protest peacefully. He also learnt how to put demands in a peaceful way and how to organize and get people into the streets. The movement’s success resulted from the massive support received from the youth and eventually across the entire population. The movement’s team work and skill in planning, organizing and mobilizing paid off. The government’s reaction only served to strengthen and catalyze the movement’s success. The use of non violent techniques learnt from the Serbian experience solidified the movement’s success.

Power Generation from Radio Wave Technology

Power Generation from Radio Wave Technology Introduction Radio wave technology is the use of airwaves in transmitting and receiving information. It is the foundation of most of our communication in the present day. Radio waves fall under the group of waves termed electromagnetic radiation, which travel at the speed of light (3108 m/s).Advertising We will write a custom research paper sample on Power Generation from Radio Wave Technology specifically for you for only $16.05 $11/page Learn More These types of waves (including light, infrared, microwaves and x-rays) are classified based on their wavelengths and frequencies. The frequencies of radio waves lie between 300GHz to 3 kHz with wavelengths of 1mm to 100km. Some of the communication equipments that use radio waves include satellite dishes, radar, radios, television, mobile phones and wireless internet. The use of radio waves for powering electronic devices had not been exploited due to the nature of waves to weaken and dissipate as they spread du e to their interaction with other waves and matter. Recently, a growing interest in alternative sources of energy that could provide efficient power in remote and sensitive locations has led to research into radio wave power generation. This paper looks at the history of radio waves and how power can be generated from them and how it can be applied in electronic devices. History and growth of radio wave technology The history of radio waves as medium for transmitting information started way back in the 1860s when James Clerk Maxwell, a physicist from Scotland, envisaged the existence of the waves. His prediction was enhanced in 1886 by Heinrich Rudolph Hertz, a German physicist, who went a notch further to show how variation of electric current could be sent into space as radio waves (Bellis 3). He was able to generate and compute the first waves by using an oscillator for transmitting the waves and a metal loop for detecting them (Parker 3). In 1895 Guglielmo Marconi, from Italy, s ent a radio signal over a distance of 100m and received it. He used crafted antenna, transmitter, and condenser and had connections on the ground that could receive the signals. He also sent a wireless signal across the English Channel in 1899(Bellis 5), a distance of 3.5 miles. In addition, Nikola Tesla helped in developing and enhancing wireless radio transmitters.Advertising Looking for research paper on natural sciences? Let's see if we can help you!

In 1899, the U.S Army adopted the wireless system and in 1901, the Navy also adopted the system. Lee Deforest invented the space telegraph in the early 1900s where amplifiers were used to strengthen weak signals (Bellis 12). Marconi was able to transmit voice in 1914 over a distance of 50 miles (Bellis 12). Over time, many people aided in developing and enhancing radio wave communicati on and today we have 4G technologies that send information at very high speeds, besides audio and video streaming. Power generation using radio waves Electromagnetic radiation and photons Electromagnetic waves can be said to have an atomic structure and can either generate or expend energy (â€Å"Electromagnetic waves† par. 7). The electromagnetic radiation, in quantum terms, is said to have photons transporting energy (Joules). A single photon has energy equal to hf. h is Planck’s constant =6.62610-34 J s and f =frequency of photon v is the velocity of light= 3108 m/s and ÃŽ » =wavelength of photonAdvertising We will write a custom research paper sample on Power Generation from Radio Wave Technology specifically for you for only $16.05 $11/page Learn More Collection of radio waves energy Radio wave energy can be collected and harnessed using various equipments and components. The generation circuit has components such as antenna, capacitors , diodes, transistors, inductors and resistors. The antenna is used for receiving the electromagnetic signal. This signal received is then rectified. The rectifying circuit is made of diodes. Once the signal has been rectified, it is boosted before being stored in capacitors. The power stored is used to drive a load or resistor via a switching circuit. Figure 1: Block diagram for ground circuit for capturing radio waves Figure 2: Circuit diagram for capturing and generating power from radio waves MOS transistors are used for switching or controlling the stored power to the load. The source of the MOSFET (for switching) is connected to the storage capacitor with the drain connected to the load. The link between the capacitor and load is created when the voltage of the stored charge is equivalent to the sum of the threshold voltages of both MOSFETs (Ishida et al. 4). Potential of radio wave harvesting Radio wave energy can be efficiently and sufficiently harvested if various facto rs are considered.

The power generated can be used in devices such as: LED monitor lights Sensors LCD display thermometer Implants in the biomedical field Charging the battery for cell phones Safety hard hat Possibility of radio waves technology replacing batteries Nowadays, there is a high requirement for efficient energy sources. Furthermore, the sources should be mobile and flexible. Batteries are usually bulky, require regular maintenance and have a limited life and as such require constant replacement. With the rapid advancement in technology where electronic gadgets and devices are continually made smaller and efficient, their energy requirements have decreased over time. Proper harnessing of radio wave energy could provide an alternative source of energy for powering small electrical devices such as sensors. This is through capturing the electricity produced by the radio waves and is depended on how far the transmitter is and the magnitude of the power generated by the transmitter. The power that can be harnessed from these waves is in the range of microwatts to milliwatts which can be sufficient for powering the devices especially in remote locations. Thus, there is a possibility of radio waves technology replacing batteries. Conclusion and personal thought about radio wave technology application in future Energy harnessed from wasted radio waves is small. This energ y may not be adequate to power large electronic devices but technology has been changing very rapidly in the recent years. Many companies are developing gadgets that are very small, thus requiring less power. For example, the mobile phone industry has seen a reduction in the size of the phones but with more installed phone features and applications. Nokia has come up with a harvesting device embedded in a cell phone. This device is able to charge the phone’s battery (Dixon 3). This means that in the future, many miniature gadgets will have been developed which will totally rely on radio frequency energy. Furthermore, radio wave energy will provide a reliable source of energy since the use of cell phones, television, radios and other communication devices is on the rise. Bellis, Mary.

Strategic Human Resource Management - Essay Example Thus, this paper presents different forms of discrimination alongside the related case of the famous footballer, John Terry, who was once involved in a racial kind of discrimination. To start with, discrimination at the workplace can be on the basis of racial differences. Racial discrimination is the act of looking down upon somebody in the workplace due to his race, color or ethical origin. This kind of discrimination can emanate during hiring and firing. For instance, one applies for a job that he or she has excellent qualifications, but he or she is not hired because the rest of employees are not confortable dealing with somebody from that race. It can also be evident in payment, whereby a fellow employee of a preferred race at the same level of management with the same expertise as one from a discriminated race earns more (Dipboye & Colella, 2005). Secondly, religious discrimination in workplace is a common scenario especially in organizations that are conservative and run on a religious basis. Religious discrimination is basically looking down upon somebody in their employment because of their religion, beliefs and practices. This kind of discrimination can be manifested during hiring and firing. Some organizations might opt to hire employee from a certain denomination and not the other thus creating unhealthy working conditions. Religious discrimination can also be in form of harassment based on religious belonging. Gender discrimination is the main and most common misconduct in employments all over the world. Gender discrimination is differential treatment of an individual in their workplace just because they are male or female. This kind of discrimination is evident when a certain gender is preferred for a certain job. For instance, the fact that the company’s long term serving clients are confortable dealing with men, a woman might be fired. The company management may attribute this firing to cutbacks and reorganization but

Billy Elliot Essay Example | Topics and Well Written Essays - 500 words

Billy Elliot - Essay Example In the scene, he tap dances away his frustration to the music of ‘a town called malice’ by the jam. Dancing appears as a vocation for Billy as he fights stereotypes from his father and brother to pursue dancing rather than the coalmining embraced by his family. Billy’s tap dance scene is significant as the dialogue between the four characters in the scene collide. The scene witnesses Billy’s brother, father, himself, and Mrs. Wilkinson. The dialogue of the four characters on Billy’s future informs the audience much about them. Mrs. Wilkinson and Tony hurl abuse at each other showing both their concern and love for Billy, although from varying perspectives (Daldry). Their abuse shows that they both care for Billy’s future albeit from their own narrow views of what he should become and pursue. Both characters are frustrated about each other’s view on Billy’s future yet they all want the best for him. The scene opens up in the kitchen which provides the audience with a claustrophobia feeling. This setting is vital in displaying Billy’s internal conflict at the time. He struggles to deal with societal and familial expectations placed on him. Mrs. Wilkinson, his dance teacher expects him to becom e a potential success while he also gets tasked with caring for her grandmother suffering from dementia. He also struggles against the gender role stereotypes entrenched in society. The camera shots during the scene also indicate the difference in class and discourse between Billy and the three adults at the table. The camera moves back and forth from the high angle of Billy perspective to the eye level shots of the adults. The difference in points of view in the scene represents the discourse on Billy’s perception about himself and what the adults think of him. When Billy tap dances angrily in the scene, it represents that dancing is a vocation for him. His dance alludes to the fact that he can dance his pain away (Daldry). This shows that
