Contemporary Latino Film - Essay Example The first three films of Inarritu depicted his unique style of storytelling having multiple stories with non-chronological scenes which were interconnected to one another. Biutiful was not a film in that style of storytelling rather it had linear and chronological events occurring (Deleyto 19). 21 grams is a story of three individuals who come from different walks of life and somehow their stories connect to each other. The director shows the past, present and future of every character with scenes set non-chronologically. The main issue is an accident and how it changed the lives of the three individuals. The film plot shows scenes from the past and the future arrangement (Russo 63). The main characters are Jack, Paul and Cristina. Jack is an ex-convict who has been sent and released from prison several times, and then he is finding his new religious faith in order to overcome his drug addiction. Paul is a mathematician who is living his last days due to a bad heart condition and nee ds an organ donor. His wife continually insists to donate his sperm so that she could get pregnant even after he dies. The third character is Cristina who was a former drug addict and is recovering towards a normal life with her husband and children. The three individuals connect to each other when Cristina’s family is killed by Jack in an accident and the heart of her husband is donated to Paul who starts to recover. Paul wants to start a new life but is not content with his wife’s constant forcing to donate his sperm, and also finds out she has had an abortion in the past, thus Paul leaves her and sets off to find out his heart donor. Cristina had returned to drugs when Paul finds out about her and they both get into a relationship. Both of them make a plan to murder Jack for what he did with Cristina’s family after he had been released. Jack, on the other hand is extremely guilty and after he is released he leaves his family. When Paul and Cristina find out w here Jack is living they go to him, and Paul takes him to a corner with the intention to kill him. When Paul fails to do so, he tells Jack to simply disappear and lies to Cristina about Jack’s death. The same night, Jack returns to the couple due to guilt and Cristina starts beating him. Paul suffers a heart attack and to avoid dying from asphyxia, he shoots himself. Cristina’s revenge remains unresolved and Jack returns to his family in the end. The urge for revenge of Cristina and the guilt of Jack resulted in the death of the relatively innocent Paul (Ebert 705). 21 Grams is a powerful dramatic film with themes such as death occurs by chance not by choice, our lives are tragic, appreciate relationships, life goes on, looking at life beyond money and God. Some of the most powerful relationships are also presented in the film including mother and daughter, father and son, men and women which resulted in a fusion of a dramatic film plot. The film Biutiful is about a si ngle parent who rises up his children in the worst conditions of a poor family living in Barcelona. Uxbal does not have a stable job and yet takes good care of his children like a responsible parent; providing food, care, after-school care etc. Soon after he finds out that he is suffering from a terminal disease which is incurable and he has

Batteries Research Paper Example | Topics and Well Written Essays - 1000 words

Batteries - Research Paper Example Starter batteries are mainly used in applications that require short bursts of high power and are, mainly used in vehicles. Deep cycle batteries tolerate deep discharge; hence produce steady power for a considerate amount of time. Industrial batteries produce low but steady power for longer periods (Leadacidbatteryinfo.org, 2015). A normal lead acid battery consists of a combination of electro-chemical cells. The cells form the building blocks of the battery. The basic components of the cell are the anode, cathode, electrolyte and a separator. The anode consists of metal mesh that is pasted with lead oxide while the cathode is covered with lead. The anode, which is the positive electrode, receives electrons from the circuit when the cell is discharged. The cathode, which is the negative electrode, donates electrons while the electrolyte provides a mechanism for the charge to flow from the cathode to the anode. The electrolyte is usually a solution of sulphuric acid (30%) and water (70%). The separator ensures the electrodes are electrically isolated. The lead and lead and lead oxide grids are given a porous structure to increase the active surface. Due to positive grid corrosion, the thickness of the anode affects the lifetime of the battery; the thicker the plate, the longer the lifespan. dQ/dt = ï  ¥Ã¯â‚¬ ªÃ¯  ³Ã¯â‚¬ ªÃ¯ â€Ã¯â‚¬ ´Ã¯â‚¬  where ï  ¥Ã¯â‚¬  Ã¯â‚¬ ½Ã¯â‚¬  Stefan-Boltzmann constant (5.67*10-8),ï€  Ã¯  ³Ã¯â‚¬  Ã¯â‚¬ ½Ã¯â‚¬  emission ratio of the material (0.95 for battery containers)ï€ ¬Ã¯â‚¬  Ã¯ â€ is temperature in Kelvins. Example when T = 298K (Kiehne, 2003), The anode receives electrons from the external circuit. The electrons then react with active materials at the anode through the reduction reaction, which then continue the charge flow through the solution of the electrolyte. The lead oxide is converted to lead sulphate and absorps HSO4 and H+. Water is hence generated from the process. Oxidation occurs at the cathode. The
