Mesoporous Silica Nanoparticle (MNS) Properties

Mesoporous Silica Nanoparticle (MNS) Properties INTRODUCTION 1.1 Background Study Large amount of solid remnant from agriculture industries waste can create disposal problem to environment such as generation of odour and can attract pests that can endangered human health. Due to this problem the application of this waste is widely explored to control the disposal problem. According to Norsuraya, Fazlena and Norshasyimi (2016), primary fuel source and additive in construction industries utilise the application of solid residue. The example agricultural waste is corn cob, rice husk, sugarcane leaf and bagasse. Studies have been conducted to enhance the use of this solid residue into profitable product. One of the important element present in the waste is silica that has wide application. According to Norsuraya, Fazlena and Norshasyimi (2016), among the agriculture residue sugarcane bagasse ash (SCBA) consist the highest of the silica content with the value of 96.93%. This studies comply with the studies conducted by Rahman et al. (2015), that stated the amount of silica content in SCBA is more than 50%. Bagasse ash is the product of combustion of bagasse that are commonly used as a source energy to operate plant. Bagasse is one waste product in sugar industry that incurs additional disposal cost. Bagasse is cellular fiber remaining after extraction of the sugar-bearing juice from sugarcane. It consist of lignin (20-30 %), cellulose (40-45 %) and hemicelluloses (30-35 %) (Peng et al., 2009). The silica content varies depending on the environment, soil nature and the process involves in harvesting it. In Malaysia the application of Sugarcane Bagasse (SCB) is still not widely explored but studies already conducted to produce silica gel as adsorbent, additive for concrete, cosmetic and others because of its characteristic. SCB is more related to by-product in sugarcane mills industry. After the juice containing sucrose called as table sugar extracted from the sugarcane by pressing the sugarcane. The residue is the SCB which contains high fibrous residue. The largest sugarcane plantation in Malaysia is at the northern region of Malaysia which can produce more than 70 000 tonne of sugarcane. The sugarcane bagasse waste from the extraction process contribute to huge disposal waste problem. SCBA can be the most valuable stock for production of mesoporous silica that are useful application such as adsorption and catalyst (Rahman et al., 2015). For that purposes, the size and surface area of the mesoporous silica are importance. Mesoporous silica is a silica that has pore with diameter range of 2 50 nm depending on the process of synthesis of the mesoporous silica. The large surface area of the mesoporous silica functions as the active site that useful for the application such adsorption. Dye is a natural or synthetic materials that can add a specific colour onto the material that are applied to. Every year more than 10 000 types of dye are produced around the world and are used in different types of industries (Malakootian et al., 2015). The application of dye used widely from food industry to textile industry with the biggest consumer of dye is textile industry. This industry is known to be the one of the main contributor of industrial wastewater pollution and it is the most polluting of all the industrial sector. 10-50% of the dye will end up in the effluent (Axelsson et al., 2006). Dye are significantly toxic and mutagenic that poses hazard to aquatic life and living organism. One of example of dye is methylene blue (MB) that are an important aromatic compound with chemical formula of C16H18ClN3S. Large amount of this dye are released in the water sources and according to Malakootian et al. (2015) it is more importance removing dye from textile wastewater than tre ating other colourless organic and inorganic because only a small amount of dye can affect the water quality and colour. Various treatment method introduce to removes dye from textile wastewater such as physical, chemical and biological but it is not effective due to complex chemical structure that lead to resistant to this type of treatment other than the treatment cost. Thus, it is important to find other alternative process of removal of dye. Currently, the most known method to treat textile wastewater is by using adsorption process method because of it has more advantages compared to traditional method especially in environmental aspects and its ease of operation, cost effectiveness, biodegradability as well as greater efficiency. In order to carry out the adsorption, the main important thing is the adsorbent. According to Malakootian et al. (2015) the most typical adsorbent used for adsorption treatment for the removal of dyes from coloured water or wastewater, but due to its high production, regeneration and reactivation procedures cost research has been concentrated on alternative adsorbents with high adsorptive capacity and low cost such as mesoporous silica nanoparticle (MSN). These adsorbents have high efficiency due to their high surface area, high mechanical properties and good resistivity to thermal degradation, and they exist in several structures and amphoteric properties. 1.2 Problem Statement The wastewater from textile contain high concentration of dye. So it required for the effluent from the industry to undergo treatment. Wastewater resulting from these industries is generally characterize by high COD, pH, dissolved solid temperature and dye and surfactant content. Dye also can be toxic to environment because of its chemical properties. In order to treat effluent from textile industry that contain high percentage of dye, various method introduced and used. Examples of the methods are physical, chemical, biological, membrane separation, radiation, electrochemical, advanced oxidation, photolysis, electrochemical, sonolysis processes, etc. However, these methods are relatively ineffective because most dyes as azo reactive dyes are highly water soluble, have complex structures, and are stable to light, chemical and biological degradation, etc. Furthermore, these methods have certain disadvantages such as high capital and operational costs, secondary sludge disposal problems and the release of large volumes of toxic by-products (Malakootian et al., 2015). Among all these methods, adsorption is the best method because of its advantages and the best adsorbents is by using nanotechnology method such as Mesoporous Silica Nanoparticle. It is because it has high adsorptive capacity and low cost. 1.3 Objectives of Study The objectives of the study can be outlined as follows: To prepare Mesoporous Silica Nanoparticle (MSN) from bagasse ash To characterize the physicochemical properties of MSN. To study the potential of MSN as an environmental adsorbent in wastewater treatment 1.4 Research Scope The research is to investigate the effluent of low cost adsorbent materials which is Mesoporous Silica Nanoparticle (MSN) from bagasse ash as the adsorbent to remove the Methylene Blue. The MSN are prepared from Sol-Gel Method and then Hydrothermal Synthesis by using formaldehyde, water and without formaldehyde and water. The MSN will be characterize and will be subjected to: Fourier Transform Infrared Spectroscopy (FTIR) to identify the major functional chemical groups present in the silica Transmission Electron Microscopy (TEM) to determine the average particle size and the morphology of the materials. Brunauer-Emmett-Teller (BET) to evaluate the specific surface area. Scanning Electron Microscope (SEM) to evaluate the image of the MSN The performance of MSN adsorbent in removing methylene blue from aqueous solution will be carried out in various parameter which are: Effect of pH the aqueous methylene blue in pH 3, 5, 7, 9, 11 Effect of MSN dosage (0.1 g, 0.2 g, 0.3 g, 0.4 g and 0.5 g) Effect of initial concentration of aqueous methylene blue (10 ppm, 20 ppm, 30 ppm, 40 ppm and 50 ppm) Effect of temperature of the aqueous methylene blue (30 Â °C, 50 Â °C and 70 Â °C) The treated aqueous methylene blue dye will be characterized and subjected to UV-Visible Spectrometer (UV-Vis) to evaluate the percentage of methylene blue dye remove from the aqueous solution from adsorbent by MSN. LITERATURE REVIEW 2.1 Introduction One of the major problem in environment is water contamination. The bad effect of water contamination will affect everything in this world such as human, animals and plants. It is because water is the main elements to support all living things and earth. Nearly all of water contamination is caused by human activities. Apart from human activities, water contamination is also caused by natural waste. From long time ago, the water contamination is studied by researcher. There are many technique and method to treat and remove contaminants in the waste water. It is for preserving both human and the environment in this world. Among all contaminant in water, dye is one of the contaminant that exist in the water. The waster that contain dye is mainly from industry that related to textile industry, plastic and paper. It contain up to 10% of used dye. It is proven that dye is dangerous to all living things due to its harmful behaviour of dye molecules and their metabolites is significant for the development of strategies to diminish their desperate damaging impacts (Hebbar, Isloor, Zulhairun, Sohaimi Abdullah, Ismail, 2017). In addition to having harmful adverse effect, the presence of colour in water is visually unpleasant and can destroy the entire ecosystem. One of the most effective method to overcome the problem of effluent water containing dye is by using adsorption technique. It has been proven to be very effective by many researchers. This is because adsorption method offers more advantages compared to other method especially in environmental aspects and its ease of operation, cost effectiveness, biodegradability as well as greater efficiency. 2.2 Dyes Dyes are produced all over the world with approximately 10 000 different type of dyes produced per year and it has been used extensively in so many industries. Most common industry that utilizing dye is textile industry and estimated to utilize around 7 ÃÆ'- 105 1 ÃÆ'- 106 tons (Malakootian et al., 2015). Dyes are used to dye a textile products, fur products, and others. Dye can be originated mainly from vegetables and also animal sources. There also the existence of synthetic dye that replacing the natural sources. The main function of dye are to add colour to a certain materials such as textile. Dye are also generally utilized as part of industry such as rubber, paper, cosmetic etc. Among these different industry, textile industry positions first in utilization of dyes for colouring of fiber. The dye are constantly left as major waste in these industries. Because of their compound structure, dyes are impervious to fading on presentation of light, water and numerous chemicals and this manner are hard to be decolorized once discharged into the nature or aquatic environment. Basically, dyes are ionising and aromatic compound. Inside the dyes, there are chromophores present in them. Based on their structures of the dyes, it has aryl rings that has delocalised electron systems. These structures are said to be responsible for the adsorption of electromagnetic radiation that has varying wavelengths, based upon the energy of the electron clouds. Dye can influence aquatics life, human wellbeing and environmental framework when dye wastewaters are greatly released wastewater into water sources due to complex compound in the dye. It has big complicated molecular structure and harmful properties. It in the end rolls out improvements of ecological system and other serious pollution issues. Dye wastewaters can contain harmful organic residue with the significant mixes of phenol derivatives, aniline derivatives, organic acid and benzene derivatives (Likhar Shivramwar, 2013) 2.2.1 Classification of Dye Dyes can be characterized into a few classes as per their utilization, for example, reactive, disperse, direct, vat, sulphur, cationic, acid and solvent dyes. The classification of dyes according their application is as shown in table 2.1. Table 2.1: General dyes classification and its application (Hunger, 2003) Class Principal Substrate Application Chemical Types Acid Dyes Nylon, Wool, Silk, Paper, Inks and Leather Usually from neutral to acidic dyebaths Azo (including premetallised), antraquinone, triphenylmethane, azine, xanthene, nitro and nitroso Cationic (Basic Dyes) Paper, Polyacrylonitrile, Modified Nylon, Polyester and Inks Applied Applied from acidic dyebaths cyanine, hemicyanine, diazahemicyanine, diphenylmethane, triarylmethane, azo, azine, xanthene, acridine, oxanine and anthraquinone cotton, Direct Dyes Cotton, Rayon, Paper, Leather and Nylon Applied from neutral or slightly alkaline baths containing additional electrolyte Azo, phthalocyanine, stilbene and oxanine Dispersed Dyes Polyester, Polyamide, Acetate, Acrylic and Plastics Fine aqueous dispersions often applied by high temperature/ pressure or lower temperature carrier methods; dye may be padded on cloth and baked on or thermofixed Azo, anthraquinone, styryl, nitro and benzodifuranone Reactive Dyes Cotton, Wool, Silk and Nylon Reactive site on dye reacts with functional group on fiber to bind dye covalently under influence of heat and pH (alkaline) Solvent Azo, anthraquinone, phthalocyanine, formazan, oxanine Solvent Dyes Plastics, Gasoline, Varnishes Lacquers, Stains, Inks, Fats, Oils and Waxes Dissolution in the substrate Azo, triphenylmethane, anthraquinone and phthalocyanine cotton Sulphur Dyes Cotton and Rayon Aromatic substrate vatted with sodium sulphide and reoxidised to insoluble sulphur- containing products on fiber Indeterminate structure Vat Dyes Cotton, Rayon and Wool Water-insoluble dyes Solubilised by reducing with Sodium hydrogensulphide, then exhausted on fiber and Reoxidised Anthraquinone (including polycyclic quinines) and indigoids Synthetic dye are being used extensively used in different dyeing industry with textile is leading industry that utilize it with 56% of world dye production annually. Its effluent contain critical level of organic contaminants, which are toxic as it will create odour, bad taste, unsightly colour, foaming, etc. These substances are often resistant to degradation by biological methods and are not removed effectively by conventional physico-chemical treatment methods. Removal of these dyes from effluents in an economic fashion remains a major problem for textile industries. 2.2.2 Methylene Blue Methylene Blue (MB) or also known as Methylthioninium Chloride was first synthesized at 1876 by a German Chemist, Heinrich Caro. Paul Guttman and Paul Ehrlich used MB in the treatment of Malaria dieses in 1891. During that time also, the function of MB as a dye were discovered and were used in First World War as a biological weapon and partially staining the soldiers. MB has many uses in different field, For instance, chemists use it to detect oxidizing agents and biologists use it to stain tissue samples and detect nucleic acids. In medicine, it is used as a treatment for various illnesses and disorders, including methemoglobinemia, schizophrenia, kidney stones, and herpes infections. In aquaculture, it is used to prevent freshwater fish eggs from being infected by bacteria and fungi (Methylene blue New World Encyclopedia, 2014) In term of dye application only, MB a basic blue dye used for dyeing silk, leather, plastics, paper, and cotton mordant with tannin as well as for the production of ink and copying paper in the office supplies industry. The release of this dye to earth is troubling for both toxicological and aesthetical reasons as dye hinder light infiltration, harm the nature of the accepting streams and are toxic to food chain organisms. The dye has a synthetic origin and complex aromatic molecular structures, it is an inactive and hard to biodegrade when released into waste streams. This perspective has dependably been neglected in their discharge. The removal of synthetic dye is of incredible worry since a few dyes and their degradation products might be cancer-causing agents and poisonous and, thus, their treatment cannot rely on upon biodegradation alone. Table 2.2: Properties of Methylene Blue (MB) METHYLENE BLUE IUPAC name 7-(dimethylamino)phenothiazin-3-ylidene]-dimethylazanium;chloride Properties Molecular formula C16H18ClN3S Molar mass 319.86 g/mol Density 43 600 mg/L at 25 Â °C Melting point 100 ÂÂ °C Boiling Point Decomposes Odour Odourless Solubility in water Soluble in ethanol, chloroform; slightly soluble in pyridine; insoluble in ethyl ether Adapted from https://pubchem.ncbi.nlm.nih.gov/compound/methylene_blue#section=WIPO-IPC 2.2.3 Technologies for Dye Removal Dye are used widely in all sector to colour their product. In order to colour the product large amount of dye is used. Apart to colour their product the dye also been used as paper, and plastic. This will result in large amount of effluent containing dye as contaminant into the nature. According to study conducted by Axelsson et al. (2006), 10 50 % of the dye used in industry will go to effluent because of the dye molecule might react with hydroxyl ions in the solution giving rise to even more water-soluble hydrolysed molecules. Because of the good solubility of dye in water it will endangered the nature. It is also reported by Sapawe et al. (2012) that 15 % of the total world production of dyes is released in textile industry. This proves that from out of 7ÃÆ'-105 tons of effluent produce large number of dye is discharges as wastewater. Without further treatment to the effluent containing dye contaminant, it can cause extreme problems if not treated legitimately because of dyes are harmful, toxic, mutagenic, carcinogenic to human life as well to another living organism (Sapawe et al., 2012). To treat the dye so many method had been introduced and the best method reported by Malakootian et al. (2015), is by using adsorption method and supported by Marrakchi, Ahmed, Khanday, Asif, Hameed (2017) due to some advantages. From all types of treatment, it can be classified into three categories which are divided for the technologies which are physical, chemical and biological. However, it is hard to treat the dye because of their synthetic origin and mainly complex aromatic structure. All of these technologies possess pros and cons. 2.2.3.1 Physical and Chemical Treatment There are numerous method falls under physical and chemical treatment such as anion exchange resins, cogulations, flotation, electroflotation, electrochemical destruction, irradiation, Ozonation,adsorption, and the use of activated carbon. Physical and chemical treatment is far more effective than biological treatment in decolourizing dye but it will use more energy, chemicals, and biological process hence increasing the capital cost for the treatment (Miao, 1992). Apart from that, it will lead to secondary sludge disposal problems and the release of large volumes of toxic by-products (Malakootian et al., 2015). 2.2.3.2 Biological Treatment Biological have three stages or phases. It is because before the effluent arriving to the biological phase, it will go through some physical and chemical treatment. For comparison to the physical and chemical method, physical and chemical treatment will treated physically or chemically without going through another phases. It is reported by Malakootian et al. (2015) that biological treatment is in effective in decolorizing water because most dyes as azo reactive dyes are highly water soluble, have complex structures, and are stable to light, chemical and biological degradation. The example of biological treatment are fungal biodegradation, bacteria biodegradation, yeast biodegradation, and microbial biosorption, Biological treatment has lower capital cost compared to physical treatment and chemical treatment (Miao, 1992). 2.3 Decolorizing of Dyes by Adsorption Process Absorption has been proved as the best method for treatment wastewater containing dye. It offers noteworthy advantages over customary treatment techniques particularly from the environmental perspective and its simplicity of operation and also more prominent efficiency. Some adsorbents, which are utilized for the expulsion of dye from aqueous solutions with differing achievement include activated carbon, magnesium oxide grafted chitosan, modified bentonite, TiO2 powder, TiO2 nanotube and others. Among all these materials, activated carbon is a standout amongst the most much of the time adsorbents utilized for the removal of dye from coloured waters and wastewaters, yet because of its high generation, recovery and reactivation procedure cost, research has been concentrated on alternative adsorbents with high adsorptive capacity and low cost. Therefore, recently there has been a lot of attention toward using nanotechnology methods. Nowadays using nanomethods, especially by using Mesoporous Silica Nanoparticle, The large surface area allows for binding at a great number of active sites distributed within the framework of the porous materials. The large pores can overcome the pore-diffusion limitation and provide high-speed pathways for gas molecules (Rahman et al., 2015). Apart from that, it is reported that, Mesoporous Silica Nanoparticle which is synthesized from natural sources claimed to safe in handling, cheap and can be generated from cheap resources (Norsuraya et al., 2016) which is bagasse ash in this case. Due to this advantages, the usage and studies regarding Mesoporous Silica Nanoparticle increase exponentially as adsorbent. METHODOLOGY 3.1 Introduction The aim of this study is to synthesis Mesoporous silica from bagasse ash by using green route and to study the performance of the Mesoporous silica in wastewater treatment by utilizing aqueous methylene blue as the wastewater. The mesoporous silica is prepared by carrying out combustion of bagasse to produce bagasse ash and then using Sol-Gel method to make gel from the bagasse ash. The product of Sol-Gel method will undergo hydrothermal synthesis by using formaldehyde, water and without formaldehyde and water to synthesis Mesoporous Silica Nanoparticle (MSN). The MSN produced will be characterize by using Fourier Transform Infrared Spectroscopy (FTIR), Transmission Electron Microscopy (TEM), Brunauer-Emmett-Teller (BET), Scanning Electron Microscope (SEM). The performance study for wastewater treatment to treat aqueous methylene blue by using MSN will be test under four parameter which is the effect of pH, effect of MSN dosage, effect of initial concentration of the dye, and effect of temperature. The research methodology is summarized in the research flow chart in Figure 3.1 below. 3.2 Material and Methods In this study there are six stages of preparations and experiment.

Examples of Discipleship Essay

I believe that Dietrich Bonhoeffer and Christian Aid are two prime examples of discipleship in this century, Bonhoeffer as an individual and Christian Aid as an organisation. Bonhoeffer was a German preacher born in 1906 to a medical professor and his wife in Breslau, a small town. From an early age he wanted to serve God, and so he studied theology at university and taught and preached in both Germany and America. He returned to his homeland in 1933 to protest against the newly elected Nazi party, and joined the new Confessing Church, having rejected his previous Protestant church for bowing to Hitler’s demands. He worked in a secret training centre for new pastors, run by the confessing church, for four years, as the Gestapo closed it down in 1937. After that, and with the signs of the oppression soon to be felt by the German people becoming clearer, Bonhoeffer took a more active role in his campaigning against the Nazis, eventually leading him to a cell in a prison and the hangman’s noose in 1945. One of the main tenants of Christian discipleship is Jesus’ teaching on the mountain: pacifism and love for enemies. Bonhoeffer was an avid believer in these ideals, and wrote his still-relevant book, The Cost of Discipleship, based around those thoughts. He interpreted the maxim of â€Å"If someone strikes you on one cheek, turn to him the other also† as a call for pacifism and working out disagreements by reasoning rather than force. But Bonhoeffer was forced to challenge his own morals when the news of the violent anti-Semitism ignited by Hitler spread and several of his friends joined the German resistance. Most of those opposed to the Nazis saw that the only way to end the suffering caused by Hitler was to kill him. Public meetings were banned, and the press were heavily censored. The huge propaganda departments of the government would not allow any attempt by Bonhoeffer to spread his Christian teaching. So Bonhoeffer felt that he could be quiet, and wait until the war finished, and congratulate those that ended it, or he could play an active role in a plot to kill Hitler. Firstly he helped smuggle Jews out of Germany, but was caught and forced to give up any legitimate teaching. Forsaking any hope of reaching a peaceful end to the conflict, Bonhoeffer helped the bomb plot to assassinate Hitler. When it failed he was incarcerated, and he contemplated his deviance from Christian law. Bonhoffer had to make, on his own, one of the main questions that hangs over all belief systems: Whether the moment dictates what a person should do, or if people should always keep constant what they believe in. In his case it was between fighting evil and helping those in need or staying true to his pacifist roots. He chose to take a drastic step against some of Christ’s teachings to implement others, leading to his arrest and execution. This inevitable question still hangs over the church, and a viable answer has yet to be suggested. Christian Aid is a charity funded by numerous churches in the UK and Ireland. Although it is funded and staffed by Christians, Christian Aid will support any people in need, regardless of religion or race, and does not attempt to convert those it helps to Christianity. Although it combats poverty and need immediately and continually in global trouble areas, it also tries too stop poverty at it’s root, and was a large part of the ‘Jubilee 2000†² campaign to abolish third world debt. Christian aid has interpreted Jesus’ teaching on Discipleship and concentrated on the aid and help parts of his teaching. It would look to examples from his life: â€Å"When the sun was setting, the people brought to Jesus all who had various kinds of sickness, and laying hands on each one, he healed them† (Luke 4:40) This sort of passage, frequent in the gospels, shows that Jesus cared greatly for the needy, rejecting the idea that they somehow ‘deserved’ their punishment, and was not afraid to get dirty and ritually ‘unclean’ to help. In the same way, Christian Aid was set up by Christians who do not judge those they help, and will go to any lengths to re-enact Christ’s good work. They also follow the teaching laid down by Jesus in his parables, such as the parable of the Good Samaritan: â€Å"He went to him and bandaged his wounds, pouring on oil and wine. Then he put the man on his own Donkey, brought him to an Inn and took care of him.† (Luke 10:34) The idea of this parable, where one man steps in where others fear to tread, inspires Christian Aid a lot, as they are physically helping the needy of the world while other members of society just stand back and watch, sometimes nodding approvingly. They see this following of Jesus as being true to one of Jesus’ main teachings, â€Å"Love your neighbour as yourself† And seek to harmonise the lot of people around the world by abolishing suffering through war, poverty and disasters. As Christian Aids motto goes; â€Å"We believe in life before Death†, Christian Aid is rejecting the traditional view of the churches preaching yet not acting, and are playing an active role in the reduction of suffering. They see Jesus’ message not just as an instruction to put up with life until you die, but also as a chance to help the needy, and prove before God their faith as Christians.

The text shows the audience to be more self-critical, that the fact not to believe in a good side of a human being and the fight for important values is what separates the human being from animals.The central theme of the text, Lord of the Flies, is power. The different aspects of power shown, is the invariable corruption of power, the reality of betrayal and the influence of fear. In the text, Jack is the antagonist, his like a dictator; he uses fear to control the boys on the island and manipulates them and uses them to his own advantage such as to get food and shelter. Jack uses a story of a non-existent beast to manipulate the other boys to follow his orders/ commands. The reason why the boys follow him and sees him as a leader is because he promised †˜protection from the beast’.A quote in the text that talks about the beast: â€Å"Fancy thinking the Beast was something you could hunt and kill! You knew, didn’t you? I’m part of you? Close, close, close! I’m the reason why it’s no go? Why things are what they are? † 2. What does this text tell us about power? ————————————————- Power is often a source of violence in  Ã¢â‚¬Å"Lord of the Flies†. In Lord of the Flies the idea of power is expressed this way, imagine a world where there were no rules, no laws, and no government to oversee the running of the country.The desire for power breaks down the boundaries set by rules and order, causes strife and competition, and governs the actions of many of the boys on the island. Once achieved, power has the ability to either improve or corrupt its holder. Ralph, the more noble of t he two leaders on the island, is bettered by his position as chief; whereas Jack, the usurper, abuses his power for personal gain. This shows us two different sides of power. ————————————————- Power is often used as a source of violence in the text, â€Å"Lord of the Flies†.The idea of power is expressed differently; imagine a world where there were no rules, no laws, and no government to oversee the running of the country. In â€Å"Lord of the Flies†, to gain power was competitive which meant strife. The desire for power breaks down the boundaries set by rules and order. Being the leader meant governing a group of boys on an island. Whenever power is achieved, power was either improved or corrupted on the leader. For example, Ralph and Jack were leaders for separates groups of boys on the island, the boys had their own choice on who they wanted to follow.It was between Ralph, the more noble of the two leaders, who was the more acceptable or bettered as being ‘chief’ (leader) and coordinated the boys to build a miniature civilization on the island, and Jack, the usurper, who used fear and manipulation to abuse his power for personal gain. It was discussed amongst the boys, â€Å"Which is better–to have laws and agree, or to hunt and kill? † With one side that showed freedom and equality, the other was a dictatorship, the text showed two very different sides of power. 3.Comment on the film techniques employed by the composer of this text. How do they contribute to the meaning of Power in the text? Brook's film opens with a very creepy montage consisting of pictures of a British boarding school intercut with planes flying over London with a haunting school chorus playing in the background. Brook's use of grainy black-and-white photography, plus the lack of any comprehensive musical score (remember Tom Hanks' â⠂¬Å"Castaway†? ), accentuates the bleakness of its surroundings and feelings of isolation.The movie can hardly be expected to capture fully every single intention of this highly complex novel (most don't), but it does respect Golding's words and captures the very essence of what he wanted to say. For that alone it should be applauded. Brook is able to compose beautiful sad visuals. ***SPOILERS*** These include the kinetic editing during the hunt for Ralph, Simon's dead body floating in the water arranged by the sad school chorus (depressing moment), Piggy's tragic demise that puts the 1990s remake laughable mirrored scene to shame, and the very scary feast that occurs at night followed by the dance.That scene, consisting of quick images, scary close-ups on the savages painted faces ————————————————- It is disturbing, haunting, and visually wonderful. —— ——————————————- In Peter Brook’s film, â€Å"Lord of the Flies†, released in 1963 was a black and white film. Although it was black and white film, it’s underrated and it’s still a classic, this is preferably better than the new remakes of this film. Some scenes are considered as disturbing and haunting but visually wonderful.Brook uses a very creepy montage in the opening scene showing pictures of a British boarding school with planes flying over London and a haunting school chorus playing in the background. Brooke uses grainy black and white photography and emphasizes the bleakness of its surroundings to create a feeling of isolation, which relates to a feeling of savagery vs. civilization. With Brook being able to compose beautiful sad visuals, he is able create the scene of Piggy’s tragedy with quick images, scary closer-up shots on the savages pai nted faces of the hunters (Jack’s tribe).This scene shows influence of fear, the invariable corruption of power/ losing control and a sense of savagery vs. civilization. 4. How does this text relate to your prescribed text i. e. George Orwell’s Animal Farm? Link each text by exploring three common aspects of Power. * well the power in the  lord of the flies  is jack's rise to control and leadership. he leads an army of corrupt boys who carry out his evil orders (set the island on fire, orders to kill ralph, etc. ) * in animal farm, napoleon takes the power from snowball and forms a dictatorship. e also has minions such as the dogs who carry out his tasks and corrupt orders. ————————————————- Ralph represents a democracy while Jack represents a totalitarian form of leadership. lead the boys into savagery   —————— ——————————- Want power, Greed or selfishness bring the destruction of the societies, ————————————————- In Animal Farm the animals hated the humans and were scared that they might take back the farm. Napoleon uses it as an excuse to keep the animals working.In Lord for the Flies the littluns are afraid of the â€Å"beast†. When Jack, Ralph, and Roger went and saw the beast, which is a parachute and a man, the biguns also got scared. ————————————————- The pigs took control and the other animals were in worst condition than they were in when the humans were in control. The boys ended up disagreeing and killing each other ————————â€⠀Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€- â€Å"Lord of the flies† is very similar to the novel Animal Farm by George Orwell. They relate with a common theme of power.However, both are from different context but written for the same reason, â€Å"Lord of the Flies† is a story of humanity from a navy officer, which served in WWII, while Animal Farm is based on the Russian Revolution. The plot, the characters and the symbols are very similar. Three common aspects of power in these texts is the want of power, the control of power, the reality of betrayal. The antagonist in each text, both want power and used a belief to manipulate the others. In Animal Farm Napoleon tells the other animals to hate the humans and they were scared that the humans might take the farm back.Whereas in â€Å"Lord of the flies†, Jack tells the littleuns that there is a ‘beast’ on the island and if they worked for him, he would provide them with protection. A nother aspect is the control of power, in Animal Farm Napoleon takes the power from Snowball and forms a dictatorship. He uses the other animals to work for him, such as the dogs that carry out his tasks and corrupt orders. In â€Å"Lord of the Flies†, Jack rises to control and leadership. He carries out an army of corrupt boys to carry out his evil orders, similar to Animal Farm. Both Napoleon and Jack represent totalitarian forms of leadership.And lastly, the reality of betrayal was common in both texts. In Animal Farm the pigs had started to become like humans, wearing clothes, sleeping in beds, drinking alcohol and playing cards with humans in the farm house. The other animals saw them through a window and couldn’t tell whether they were pigs anymore or humans. In â€Å"Lord of the Flies†, Jack starts his own tribe with his hunters, the littleuns, he went to steal Piggy’s glasses, but Ralph went to look for it, then suddenly Jack stabs Ralph in the ba ck, but luckily Ralph survived.

Children s Development And Their Learning - 3537 Words

There are various areas within the teaching role that are important in order to aid children through their development. There are three key principles; Planning, Teaching and Assessment (Education Scotland, 2011). Throughout this essay I will focus on how these principles affiliate children’s development and their learning. Two English Lessons completed during the introductory placement will underpin this evaluation. Planning At the core of any planning lies the National Curriculum. Before Planning can even begin a teacher must know what the children need to learn. When the teacher gave me my topic’s I went straight to the National Curriculum. It is also important in order to plan for progression to know what they have previously covered so I arranged a meeting with the class teacher. Once all this information had been established I collated my planning. Denby, (2012) claims starting a lesson with what children already know lends itself to the importance of planning. He believes lessons must be planned to accommodate progression. It is important that teachers feel confident about what their pupils know or can do. Once this has been determined their next challenge is to plan lessons that allow children to collectively move forward. There are three key areas of planning that are covered within schools, Long-term planning, Mid-term planning and Short-term planning (Lesson planning).
