Essay on Who Controls Macbeths Mind - 784 Words

You may think that MacBeth is one hundred percent guilty and should receive a heavy punishment for his actions. But, have you ever considered the possibility that he may not have been responsible for them? Because he should not be held responsible for something he had no control over. I would like to point out that it was the Weird Sisters who told him prophesies which he then believed. It was his wife, Lady MacBeth, who pressured and convinced him to go through with the killings. And tell me, would any sane person commit the amount of crimes that MacBeth has? He has a mental condition that makes him go insane and start seeing things that are not actually there. These hallucinations are just one of the many causes that contribute to his†¦show more content†¦Ã¢â‚¬Å"When Lady MacBeth receives the letter from MacBeth telling her that he wants to kill Duncan, she fears that he would not have the courage to go through with it† (Shakespeare 31). She brings out the worst in h im and encourages him to kill King Duncan. She persuades him by constantly telling him negative things to get MacBeth to believe that he is doing the right thing. â€Å"Look like th’ innocent flower, but be the serpent under ’t† (Shakespeare 35). Lady MacBeth is the one who tells MacBeth to be this vicious creature and makes him think that killing King Duncan is okay. Because of Lady Macbeth’s behavior, MacBeth was led to become a murderer. Macbeth should not be held accountable for his actions since Lady MacBeth is the one who convinced him to commit the crime that started his madness and turn him into a monster. And now, because the Weird Sisters told him prophesies and Lady MacBeth turned MacBeth into a savage, he has become mentally ill. His insanity starts even before he kills King Duncan. â€Å"While on his way to murder the King, he is convinced he sees a bloody dagger leading him up to Duncan’s room† (Shakespeare 51). Obviously, ther e could not be a dagger hanging in front of him and actually move by itself. This hallucination is just one example of how insane he is, and this is even before he killed anyone.

Adults, too, go through modifications and experience physical, cognitive, and social changes. Adulthood has been suggested that emerges as early as 18, but for our purposes, adulthood can be divided into three periods: early adulthood (ages 20 to 39), middle adulthood (ages 40 to 65), and late adulthood (beyond age 65). In young maturity, bodily development continues.

Unlike adolescents, adult understand the contradictions inherent in thinking. They see both the possibilities and the problems in every course of action in deciding whether to start a new business, back a political candidate, move to a new place, or change jobs. Full-grown adults are more knowledgeable that youngsters or adolescents at creating logical resolution s and at correlating reason and generalization to actions, feelings, common concerns, and special affiliations. As they appreciate these relationships, their thought becomes more global, more concerned with broad moral and practical issues. The achievement of these new kinds of thinking reflects a stage of cognitive development that goes beyond Piaget’s formal operational period. In this stage, people’s thinking becomes dialectical, which means they understand that knowledge is relative, not absolute such that what is seen as wise today may have been thought foolish in times past. They see life’s contradictions as an inevitable part of reality, and they tend to weigh different solutions to problems rather than just accepting the first one that spring to mind.

It is designed to prevent any threat, caused by international trade, towards the survival of specimens of wild animals and plants. The global scale of the trading network nowadays imposes this convention to have an international scope, thus to include 181 parties protecting more than 35,000 species This treaty has 2 main purposes: it aims to improve the working of the Convention, also, ensure that CITES policy developments are mutually supportive of international environmental priorities and new international initiatives.

A difficulty to address this problem A convention such as CITES can impose total trade bans on certain species. While the reason is environmentally sound, politicians don’t always agree. The reason behind this are the commercial and economic benefits that countries get out of specific trades. For instance, the main challenge in 2013 was to add to the CITES Appendix II several species of sharks. This proposal faced a strong resistance from China, Japan and their allies, where the shark fin trade is a tradition, causing horrific changes in the population of these species. The same problem happened in 2013 during the CoP16 when Canada rejected the decision to enlist the Polar Bear in the Appendix I, due to its impact on the lives of the Inuit  Cooney, R., Abensperg-Traun, M., (2013) .

Mechanical Properties Of High Strength Steel Essay

This paper presents the mechanical properties of high strength structural steel and mild structural steel at elevated tempera- tures. Mechanical properties of structural steel at elevated temperatures are important for fire resistant design of steel structures. However, current design standards for fire resistance of steel structures are mainly based on the investigation of hot-rolled carbon steel with normal strength, such as mild steel. The performance of high strength steel at elevated temperatures is unknown. Hence, an experimental program has been carried out to investigate the mechanical properties of both high strength steel and mild steel at elevated temperatures. †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦..†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.*******†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.. 1.

The Influence Music Has on Society Free Essays

Chantal Foster College writing 21 October 2012 The influence music has on society Music has been around for thousands of years. Many people have been shaped from it differently. For some music has been a bad influence, and others it’s been a good influence. We will write a custom essay sample on The Influence Music Has on Society or any similar topic only for you Order Now Different types of music have grown rapidly in these past few years. Throughout the years music has changed the way it influences people. In earlier years music was used more for celebration and now music is used to voice your opinion and try to influence your audience to believe what you stand for. Music is usually one of the highly blamed sources for the influences on society today. Many people are influenced by music they listen to. Mostly because they want to copy their favorite artist or because they feel that’s a way of expressing themselves and fitting in with the people that are into the same music. It’s also a way to find similar things to other people who listen to different music. Music influences how people act, what people do and our religion. Some ways that society has been influenced by music is, for example music can dictate how a person speaks. In most rap songs its most rappers rap with mostly slang words, so most people think it’s cool to talk just like them. Some slang words that rappers would use that society uses today are â€Å"crib† which means house and most people use that slang today. Then society talks like them and stick to talking like that for the rest of their life, and that makes them the person they are today. Another way music has influenced society is the way society dresses. For example, in some music videos rappers have on baggy jeans, showing their draws. Most people watch those videos and get ideas from it, and start dressing just like them. In some songs the artists has a certain style of clothing that looks really nice. This could be a good inspiration on society. Many people try to dress nice like them, and set a style for their selves. For example an artist might talk about all the different clothing and styles they wear and then have on some of the amazing clothing. That makes people want to buy some and wear it like their favorite rapper or singer. This is one of the good influences on society. Music can also influence the way we act, feel and believe in sometimes. There are so many different types of music that can influence society. Like christian music, this type of music influences to believe in something. Religion has always had music of some form and the songs that they sing influence people to believe in their god. Music can sometimes dictate us towards what religion we might be interested in or the way we feel about a certain subject or concept in life. Firstly Christian music influences them to believe more in there God and is a way they gain love with God. Secondly the songs are usually about joyous things and make the audience feel happy, which inspires them to do good things. The lyrics in Christian songs are about either doing good or praising God. The songs about doing good influence the listener to want to help others and show love to everyone. This is one of the good ways music influences society. Some of the bad influences that music has had on society is when music starts to talk about drugs, murders,and sex. Most of the violent acts that society does is blamed on music, for the simple fact that most rappers talk about â€Å"shooting† or â€Å"fighting† their enemies.

Photovoltaic Cells

Questtion: Describe about photovoltaic cells? Answers: Environmental considerations The importance of sustainability: Sustainability is the meeting of the needs of the present generation without compromising the ability of future generations to meet theirs. The sustainability has many aspects like environmental, social, and economical.. Photovoltaic (PV) is a renewable energy technology that converts solar radiation directly into electricity. Solar energy is abundantly available; the Earth receives enough solar energy every hour to meet the worlds annual energy needs (Archer and Hill, 2001) .The electrical power which has been produced from PV is less attractive than the electrical power produced by modern technology because of its long payback time. But nowadays incase of mixing of the energy for future, PV is most important because of the rising energy cost and drooping production cost ((Archer and Hill, 2001). So the sustainability of PV power is important. The sun is the renewable source of a photovoltaic cell using ultra thin high efficiency wafers in crystalline solar cell; reduce the carbon footprints of crystalline solar cell. Though recent studies have shown that the life cycle green house gas emission of PV systems as low as 37 g CO2 eq/KWH. It is 4% low compared to coal based power plants. Photovoltaic solar cell converts the sunlight to electricity. Photovoltaic cell uses array to capture the solar energy and convert into electricity. The general theory behind the PV cell is that the solar cell absorbs the incoming solar radiation. The electrons of the solar cell are promoted by the energy that is stored in the photon. Solar radiation represents such an infinite source of energy for the Earth. The sun delivers 1.2 1014 kW energy on the Earth, which is about 10.000 times more than the present energy consumption (Ho, 2007). The energy that the Earth receives from the sun in just one hour is equal to the total amount of energy consumed by humans in one year. So photovoltaic cell is being considered as the significant contributor to renewable energy. The crystalline silicon cells in photovoltaic cell are most expensive, so instead of these cells thin film cells are more affordable. But its efficiency lies below 10 percent. Nanocrystalline dye cell can also be used with 5 percent efficiency. These are the innovation of solar technology that made the system more affordable. The photovoltaic energy is used in MSU sustainable house. Fundamentals of photovoltaic cell: The solar cell is called photovoltaic cell. These cells are found in solar powered calculator or on satellite for creating the electrical energy. These cells convert light energy to electrical energy directly .These cells are made up of silicon. A silicon atom consists of 14 electrons which are arranged in 3 general electron shells. The first 2 cell which are nearest to the nucleus, are full. The outer shell half full comprises 4 electrons. Silicon can share its electron with its neighbor where in case of crystalline silicon; other silicon atoms provide electrons to share. The mathematical parameters used to evaluate the performance and efficiency of the various types of the various types of Photovoltaic cell The important parameter of the PV performance is called the Fill Factor (FF). It is a term that describes how the curve fills the rectangle that is defined by (V oc) and (Isc). It gives an indication of the quality of a cell's semiconductor junction and measures of how well a solar cell is able to collect the carriers generated by light (Hajizadeh et al. 2011). It is defined as: FF (1)=Vmp Imp/VIsc (1) After a simple manipulation, one gets the equation: V oc I SC FF = V mp I mp = Pmax (2) It can be easily observed that FF is always less than unity and differs from material to material. The closer the value of the fill factor is to unity, the better the operation of the PV cell. The PV efficiency () is defined as the ratio of the maximum output power P mp to the solar power received by the cell surface area (A): = FFI scV sc / GA A five parameter photovoltaic model is adapted in this study to determine the module parameters. In the present work, the five parameter model is used to simulate the characteristic of thin film solar cells at different weather conditions. In addition identify what type of voltage is produced and the wattage ,how the power is regulated to battery or more importantly to an inverter to mains power. A single PV cell produces about 1 to 2 watts of electricity; an amount that is quite insignificant compared to what is required by most electrical equipment. Two or more PV Cells are built to produce a PV Module to provide higher wattages as required. For instance, a PV module producing 50 watts may comprise of at least 25 of 2 Watts output PV cells. To meet the the electrical need of a home or an industrial setting, PV Modules are assembled together to form a PV Array that meets the total energy requirement. A PVC system design begins with determining the total energy requirement for a facility to be powered. Next the number of solar panel units required and other components of the PVC (description below) are determined. A basic PVC system comprises of the following: Solar panels collects visible light from Sun and converts it to electricity (direct current (DC)); Batteries (rechargeable) Store solar energy up to provide electricity for sun-down periods (nights and cloudy days). They must be able to discharge and recharge. Rechargeable batteries are a little more expensive than the disposable batteries. Without batteries a PVC system can only provide electricity when it is sunny. Charge Controller- feeds electricity from the solar panel to the batteries in a manner that prevents the solar panel from overcharging the batteries. Power Inverter converts the low-voltage direct currents (DC) from the battery to high-voltage alternating current (AC) How A Pv Cell Is Made And How It Works What is the PV slab made of: The slab or wafer is mainly made of silicon. On the top of the slab there is very thinly phosphorous is diffused and on the base of the slab, boron is diffused, . The boron side of the slab is 1,000 times thicker than the phosphorous side and the phosphorous has one more electron in its outer shell than silicon, and the boron has one less. What chemical bonding takes place on the surface: The photovoltaic cell is essentially a diode with a large surface and there is covalent bond. What are the dopants and what part do they play in the design process: In a crystalline silicon PV cell, p-type silicon must contact n-type silicon to create the built-in electrical field. The process of doping, which is used to create these materials, introduces an atom of another element into silicon crystal to alter its electrical properties. Thedopant, which is the introduced element, has either three or five valence electronswhich is one less or one more than silicon's four. The most common method of doping is to coat a layer of silicon material with phosphorus and then heat the surface How does boron affect the electron flow A thicker, boron doped bottom layer contains holes, or absences of electrons, that also can move freely. In effect, precise manufacturing has instilled an electronic imbalance between the two layers. What is meant by p-type and n-type and the electrical charge between them: P-type (or positive) semiconductors have an abundance of positively charged holes, and n-type (or negative) semiconductors have an abundance of negatively charged electrons. When n- and p-type silicon layers contact, excess electrons move from the n-type side to the p-type side. The result is a buildup of positive charge along the n-type side of the interface and a buildup of negative charge along the p-type side(Nadeau,2011). Because of the flow of electrons and holes, the two semiconductors behave like a battery, creating an electric field at the surface where they meet. That is called thep/n junction. The electrical field causes the electrons to move from the semiconductor toward the negative surface, making them available for the electrical circuit. At the same time, the holes move in the opposite direction, toward the positive surface, where they await incoming electrons. How is the electrical current being produced. Same as above How Do Photovoltaic Cells Work How does light get converted into electrical energy: In a crystal, the bonds between the silicon atoms are made of electrons that are shared between all of the atoms of the crystals. When the light gets absorbed, one electron in one of the bond gets excited up to a higher energy level and can move around more freely than its boundation phase. Then we can get current. A photon comes in and activates the electron on to high energy level. What is photoelectronic effect: Some materials which show the photo electronic effect ,they can absorb the photons of the light and release electrons because of this effect. Where was it discovered and by whom: The photo electronic effect was first noticed by French physicist, Edmund Bequerel, in 1939. Why non reflective coatings used: The non reflective coatings are used in silicon cells because these coatings allow entering the highest amount of light in the cell. Explain how electrons are knocked loose from the atoms in the semiconductor material: The solar cell which is also called photovoltaic cell is mainly composed of semiconductor. When the light strikes the cell, the semiconductor absorbs the portion of light, so the electrons of the semiconductors are knocked loose. For this, electrons can flow freely and can create a current. What does the band gap control in a PV cell: Band gap is called energy gap. In this gap no electron states can exist. The band gap is the energy difference between the top of the valence bond and the bottom of conduction bond in insulator and semiconductor. The energy is equivalent to the energy which is needed to free an outer shell electron from its orbit. For this reason electrons can move freely within the solid material. Band gap determines the electrical conductivity of the solid. The semi conductor has small band gap whether the insulator has large band gap. Illustrate and explain the different each substrate used to construct a the PV cell: The majority of multi-junction cells have used three layers . However, the triple junction cells require the use of semiconductors that can be tuned to specific frequencies, it is made of gallium arsenide (GaAs) compounds, often germanium for the bottom-, GaAs for the middle-, and GaInP2(Gallium Indium Phosphate) for the top-cell.Gallium arsenide substrate:Dual junction cells can be made on Gallium arsenide wafers. Alloys of Indium gallium phosphide in the range .In.5Ga.5P through In.53Ga.47P serve as the high band gap alloy.Germanium substrate:Triple junction cells consisting of Indium gallium phosphide, Gallium arsenide or Indium gallium arsenide and Germanium can be made of germanium wafers. Early cells used straight gallium arsenide in the middle junction. Indium phosphide substrate:Indium phosphide may be used as a substrate to fabricate cells with band gaps between 1.35eV and 0.74eV. Indium Phosphide has a band gap of 1.35eV. Indium gallium arsenide(In0.53Ga0.47As) is lattice m atched to Indium Phosphide with a band gap of 0.74eV.Indium Gallium Nitride:Indium gallium nitride (InGaN, InxGa1-xN) is a semiconductor material made of a mix of gallium nitride (GaN) and indium nitride (InN). Conclusion Conclusion The deployment of solar technologies for energy production at a large scale requires the involvement of both political and economical players, but also further improvements in the conversion efficiency and reduction of manufacturing cost. A large ongoing research effort aims to find innovative solutions to overcome these barriers. In the last decade, photovoltaic technologies have experienced an astonishing evolution that led to the increase of the efficiency of crystal-silicon solar cells up to 25% and of thin-film devices up to 19%. Recently, nano-technology, innovative deposition and growth techniques, and novel materials opened routes for reaching higher performances (multijunction devices and other 3rd generation photovoltaics) and for developing very low-cost devices such as organic-based PVs. All these technologies face comparable fundamental issues related to the steps involved in the conversion of photon energy into electricity: photon absorption, charge carrier g eneration, charge separation, and charge transport. Both fundamental research and technical development are critical requirements for these technologies to become more efficient, stable, and reliable. Solar thermal systems are at the demonstration stage and some installations are already operational. Their ability to overcome the intermittency problem using hybridization and thermal storage renders these technologies particularly suitable for large-scale electricity production. Direct production of chemicals fuels, and particularly hydrogen, from solar energy is a promising alternative to using fossil fuels for the development of a sustainable carbon-free fuel economy (Collins, 2005). Thermochemical and biological conversion processes are GCEP Solar Energy Technology Assessment - Summer 2006 37 promising technologies with potential for high efficiency. However, only a few thermochemical processes have been investigated to date and biological systems require more understating of gene tics and biological conversion to become efficient and stable (Collins, 2005). Solar energy has a large potential to be a major fraction of a future carbon-free energy portfolio, but technological advances and breakthroughs are necessary to overcome low conversion efficiency and high cost of presently available systems.
