The impcat of the drug culture on the Rock music industry of the 70's - Research Paper Example se of the Soviet Union which effectively brought the Cold War to an end, creating a suitable condition for the society to thrive and prosper politically, economically and socio-culturally. Therefore, the drug culture emerged as a means of assuring stable and healthy living, through fighting diseases and illnesses that were commonly associated with the previous war periods, to give people more freedom to enjoy life (). Thus, many drugs were invented to play different roles, with some targeted at preventing and curing diseases, while others were meant to keep people alert, help people sleep, to lessen their worry and anxiety and alleviate pain (). Therefore, the availability of all sorts of drugs created a wave of optimism in the 1970s society, effectively impacting on the rest of the socio-cultural aspects of the society such as the lifestyles and the music development. This way, songs were written and sang about a variety of drugs, especially those drugs that provoked societal resist ance such as the hard drugs including cocaine, heroin and marijuana (). These drugs were being resisted by the society owing to their addictive and negative health implications on individuals’ mental and psychological health, yet they were perceived to offer the rest of the drug benefits such as keeping people alert making them feel high and good about themselves, as well as reducing sensitivity and increasing creativity. The influence of such drugs made artists feel inspired, while also removing the inhibitions that would disrupt performance such as tiredness, thus helping to keep the party moving (). Therefore, the influence of the drug culture was the formation of the creation of soundtracks of roll and roll to promote a revolution of celebrating drugs, and the consequent stability, peace and the joy of love and sex that came with the drug culture, in a society that was defined by obsession with wars (). In this respect therefore, the drug culture helped o promote the rock and roll

Answer 7 individual questions - Essay Example The individual cannot breakdown such proteins leading to their accumulation and final death of the host as the proteins demand for more space. Viroids contain RNA as the nucleic acid and have no protein coat. Their infection materializes in the company of viruses. A case example is the viroid, Hepatitis D usually evident in the caspid of the virus, Hepatitis B. Bacteria are ubiquitous and unlike viruses, they lack the membrane enclosing the DNA contained in their nucleus. This makes them reproduce quickly via binary fission, independent of other cells. Bacteria also adapt to new environments and replicate even faster to overwhelm the hosts immunity. Consequently, a disease is evident. Viruses in the lytic cycle attach their phage on the host cells using tail fibers. Their penetration occurs once the lysozyme cell wall opens up allowing the tail sheath to contract and enforce DNA and tail core inwards (Harvey, 2007). In this cycle, production of phage proteins and DNA transpires, followed by mellowing and assembly of phage particles prior to their release once the cell wall of lysozyme breaks. Lytic cycles lead to lysis and eventual death of host cell. Chemical bonding and signaling to produce enzymes regulate the process. Latent cycle also known as lysogeny and temperance marks a period of no virulent activity. In this case, prophage DNA may be integrated in the hosts nucleic acid inducing specialized transduction and phage conversion in the future (Tortora, Funke & Case, 2010). This results to a provirus that allows infected cells to function normally for some time. The cycle involves the production of repressor proteins, which in spontaneous occasions may fail, making the virus to enter the lytic cycle. Viruses act as co-carcinogens, in that they propagate cancer progression. In some cases, they cause cancer, though pathology results after a long time. It is said that 10% of

Interior and Spatial Design Contextual Studies Essay

Interior and Spatial Design Contextual Studies - Essay Example Generational change has also led to continuous shift in tastes. Spatial design comes in handy to sort these problems. For these reasons, this essay seeks to research and discuss the relationship between abstract painting and interior spatial design. Furthermore, the essay will include empirical studies of various artists and professionals in the field of fine arts and design. Through various reviews, I have learnt that painters and spatial designers are making immense contributions to the society. I have hence learnt that I will be in a position to create aesthetic appeal of homes. Through expertise in spatial art and interior design, I will be able to restore happiness and satisfaction to myself and the human race. Through appraisal of beauty, the field has enabled me to value specific objects in the society. I have also learnt the strategic use of interior design in drawing building plans taking into account interior spaces and probable rooming. In eventuality, they should award space appropriately to each section of a building. In my study of abstract paintings, I realized that they draw interests from everyone. On the contrary, I realized that a person who possesses a piece of an abstract painting could keep it for ages without having interpreted its meaning. Therefore, the value of such a work of art increases as time progresses in the sense that, it portrays not only its aesthetic value, but also the mysterious thought behind its conception. This misery behind the artistic works drew much interest from me, making me to relate commodities to their ideal values. Using an example of the value of money, I realized that everyone understands the importance of money and its value. However, people seem not to understand the real value of the money which is reflected by the purchasing potential as opposed to indicated numerical value indicated. In this respect, I have come to the conclusion that some abstract

Alternative energy Research Paper Example | Topics and Well Written Essays - 1250 words

Alternative energy - Research Paper Example solution to the most critical problems that the world has today, especially in reducing the concentration of carbon dioxide in the atmosphere, which deteriorates global warming (International Energy Agency, "Solar Energy Perspectives"). Solar energy is, by far, the most experienced form of energy due to its accessibility, and the ease of converting solar energy to electricity. Many solar energy conversion technologies present sustainable and promising potentials in providing renewable energy that does not only reduces the cost of electricity but could also deliver effective mitigating solutions to the environmental problems we have today. The International Energy Agency expresses its confidence over the positive impacts that solar energies could bring to the world. The agency states that the creation of low-cost, unlimited and untainted solar energy technologies will have "huge longer-term benefits" (International Energy Agency, "Solar Energy Perspectives"). The energy agency adds that the stable generation of solar power through the use of solar energy conversion technologies will ensure energy security in many countries; and will cut dependence on power plants that use radioactive materials, which are potentially pernicious to human health. It will also lower down the energy cost, improve sustainability, will help reduce pollution, and will lessen the effects of climate change. Therefore, the agency stresses that since this innovative approach requires substantial amount of financial investments, a careful planning must be employed for an efficient expenditure of financial resources (International Energy Agency, "S olar Energy Perspectives"). Normally, the Earth obtains a sizeable load of radiation from the sun. On average, our planet takes at least 174 pent watts of solar energy (Smil 240). Of this, 70 percent is absorbed by the Earth by the clouds, oceans, and ground forms including the mountains and the plains among others. The sun’s rays could either be

A reflective paper Essay Example | Topics and Well Written Essays - 500 words

A reflective paper - Essay Example One day, as I was checking my emails, I saw an email titled â€Å"Congratulations! You won the Lottery Competition.† I quickly tried to think which lottery had I applied in that I might have won, but nothing came to my mind. I opened the email, and it said that I had been randomly chosen by a company through my email address for a lottery with a prize worth $10,00,000 few months ago, and that in the latest lucky draw, my email was the one that was picked for the first prize from among hundreds of thousands of email addresses. My adrenaline level increased and I could feel sparks flash down by spine. Just by the mere thought of becoming a million dollar richer overnight, I was having goose-bumps. My stomach was lurching with excitement and I almost screamed. My sister playing at a distance of a few yards came running towards me and asked what had happened. I said, â€Å"Anna, I won the lottery!† She asked me to show her the email and I did. She also got very excited but I’m sure a bit jealous too. The next thing I did was read the email in detail so as to know how to get to the money. The email showed the complete procedure. It required me to give them my name, my identity card number, my bank account number, my citizenship, my country and such other details. I wondered why somebody might need so many details to transfer the money to my bank account. Principally, the bank account number should have sufficed. I kept reading further to find that the company also required a down-payment of $100 from me first as a processing fee. I thought what to do. The opportunity was too big to forget but depositing $100 was not easy either as I didn’t have any money as I did not do any job at that time. I replied to the email asking them to deduct $100 from my prize money and send me the balance, but the next day I got their response saying that the company’s law did not allow that. I decided to consult my parents and friends. When I did, they told me to beware and

Baz Luhrmans modern interpretation of the Shakespeare play Essay Example for Free

Baz Luhrmans modern interpretation of the Shakespeare play Essay This essay is based on Baz Luhrmans modern interpretation of the Shakespeare play; Romeo + Juliet. It will be focusing on the opening scene, and Prologue. I will be analysing how Baz Lurhman portrays the feud between the Montagues and the Capulets. I will also be discussing how the presentation of The Prologue helps the audience to understand the play. The film begins with a blank TV screen. The TV screen could represent the modern interpretation to the play. The screen the becomes occupied by a news-reader, who begins reciting the sonnet. The idea of the sonnet being read off the news, emphasises the how important the situation is. Once the news-reader has completed the sonnet, the TV transports you to the scene of the play; Verona. The establishing shot becomes apparent; a Montague building separated form a Capulet building, only by the statue of Christ. This emphasises the theme of religion, and the line in the sonnet: Both alike in dignity This is because each building belittles the rest of Verona, as well as the other. The camera then speeds up and shows a sequence of fast shots. This is known as mise en scene. This represents a degree of chaos, and highlights the conflict between the two families. The Prologue is then recited again, this time, by the Friar. As he reads, the words are reinforced by bold, white text, on a black background. The contrasting colours could be highlighting the two families differences. The use of colour; in this case black and white, are most likely an deliberate choice, as black and white are both immediate opposites, therefore helping the audience differentiate between text and background. This allows the audience to correlate the friars voice with the text, despite the short amount of time in which the text is shown. After the Friar has completed The Prologue, the camera focuses on a family tree, of each family; in turn. Almost as soon as it has shown the family trees, the shot becomes engulfed in flames. The flames could convey a message of hatred, rage and anger between the two families. From the flames, a newspaper heading appears, whilst the flames fade. The heading suggests re-occurring violence between both the Montagues and the Capulets, and could also show that the feud is still as strong as ever. We can then learn that the strongest of the families quarrel lies between the youth of each house. This becomes apparent when the camera focuses on a number of magazines, with the younger generation of each house on the cover. Baz Lurhman also incorporates the use of magazines, as opposed to tabloids, when referring to the youth, as younger people are usually more associated with magazines. In the next shot, the parents of each house are pictured, accompanied by the actors name and character. In turn, the same happens for every character. This is important, as it allows the audience to differentiate between the members of each family, and who the main roles are. The types of shots depicted are very solemn, except for a character named Paris. He is shown in a happy scene; as he is not involved in the feud, whilst every other character is affected, in some way, by the civil conflict. The Prologue concludes with a montage of shots, featured earlier in The Prologue, aswell as a repertoire of emotion-provoking shots, from later in the film. As the closing sequence is shown, shots of fireworks are merged in, to again, establish the theme of chaos. Finally, the title appears, and The Prologue finishes. The final aspect of Baz Luhrmans interpretation, is the Music. Without this particular piece (Carmena Burana), The Prologue would not provoke as many emotions within the audience. This is because; as the tempo, and volume rises beyond forte, Baz secrenises the action scenes to run along side this. He also utilises the piano-pianissimo parts of the piece to again, establish the sonnet. All together, the music adds the element of drama, and strong emotions to the opening scene.

Stratospheric Ozone Depletion Research

Stratospheric Ozone Depletion Research A) Effects of Ozone on the Lower Atmosphere The lower atmosphere (Troposphere) includes 75% by mass of the atmosphere (concentrated). Natural sources of Ozone in the troposphere includes lightning. Approximately 10% of all atmospheric ozone is present in the troposphere. If ozone levels reach 20ppm, they are very poisonous to humans, animals and plants. It oxidises organic tissue which disrupts the normal biochemical reactions in the body, irritates the eyes and causes breathing difficulties. It can be detrimental to plants and agriculture, as it oxidises much more readily then oxygen, killing/spoiling the agriculture and destroying it. Sources of ozone in the troposphere include diffusion from the stratosphere, internal combustion engines, petrochemical smog, naturally from lightning and photochemically when nitrogen dioxide in polluted air is decomposed by sunlight. NO2(g) NO(g) + O(g) O2(g) + O(g) O3(g) Positive effects of ozone include that it can kill bacteria and viruses in water and thus is useful in purifying water supplies. B) Effects of Ozone in the Stratosphere Contrastingly to ozone in the troposphere, Ozone in the stratosphere is essential to life on earth, as it absorbs ultraviolet (UV) radiation which can be harmful to living cells on earth as they can damage living tissues and cause skin cancers. Ozone in the stratosphere is commonly referenced to as â€Å"the ozone shield† as it protects living organisms on earth from UV rays. Ozone Reactions in the Stratosphere and their Beneficial Effects on Living Organisms Formation of Ozone in the Stratosphere O2(g) O(g) + O(g) O(g) + O2(g) → O3(g) Stratospheric oxygen absorbs UV light to form free oxygen radicals The oxygen radicals are highly reactive and combine with oxygen molecules to form an energized ozone molecule. Decomposition of Ozone in the Stratosphere O3(g) O2(g) + O(g) Due to the absorption of UV radiation, the Ozone layer acts as a radiation shield by absorbing medium and high energy UV rays. This protects living organisms as UV radiation can have very harmful effects on them including: Can cause sunburn on skin which can lead to skin cancer caused by a mutation in DNA Can form cataracts on eyes It can kill cells due to DNA readily reacting with UV rays It can impair photosynthesis in plants Many more†¦ Thus without the ozone shield in the stratosphere, life in the biosphere would be dramatically impaired and destroyed by harmful UV rays. A) Functional Groups and General Structure of Compounds Classified as CFC’s CFC’s – Chlorofluorocarbons are haloalkanes in which the hydrogen atoms have been replaced by fluorine or chlorine atoms. Haloalkanes are the products when alkanes react with halogens (members of group 7 of the periodic table). CFC’s generally contain â€Å"chloro† and â€Å"flouro† functional groups and no hydrogen atoms. The general structure of compounds classified as CFCs are haloalkanes whose hydrogens have been replaced by chlorine or fluorine atoms. E.g. B) Main Uses of CFC’s CFC’s were used as refrigerants and as propellants in aerosol spray cans. They have a variety of uses as demonstrated below. However due to the harmful effects of CFC to the environment and the ozone shield, CFCs are not used for these uses anymore. C) Reactions between CFC’s and Ozone that Result in the Destruction of Ozone in the Stratosphere. Effects of Small Concentrations of CFC’s that can Damage Large amounts of Ozone Reactions between CFCs and Ozone Synthetic CFCs are responsible for the destruction of the ozone shield, natural CFCs such as CH3Cl and HCl rarely reach the stratosphere as they readily oxidise in the troposphere. However, synthetic CFCs slowly diffuse from the troposphere into the stratosphere, where they undergo photodissociation (due to UV rays) to produce chlorine and bromine radicals that attack and destroy ozone molecules. e.g. CFC-11 Trichloroflouromethane (CFCl3) (Lifetime of 70 years) 1. In the stratosphere, the CFC comes into contact with short wavelength UV CFCl3(g) + UV → CFCl2 ·(g) + Cl ·(g) 2. The chlorine free radical then reacts with the ozone molecule Cl + O3 → ClO + O2 3. The ClO molecule reacts with free oxygen atoms which exist naturally from UV breakdown of O2 ClO + O → O2 + Cl This Cl Is then regenerated and able to attack more Ozone (Step 2) thus further demonstrating the harmful effects of even one CFC This reaction causes destruction of ozone in the stratosphere, due to the (previously used) synthetic CFCs for refrigeration, dry cleaning etc. Small Amounts of CFCs can still do harm: Evidence has shown that even small amounts of CFCs can damage large amounts of ozone. Firstly, CFCs generally have a long lifespan, ranging from approximately 57 (CFC-11) years to 333 years (CFC-12), and due to the fact that each Chlorine radical can be responsible for the breakdown of tens of thousands of ozone molecules, and due to their lifespan once released, even a small amount, will be around for many decades to come. In addition, most CFCs will almost definitely make their way up to the stratosphere as they cannot be destroyed at low altitudes as they are unreactive and they are insoluble in water and therefore cannot be washed out of the atmosphere by rain. Alternative Compounds for CFCs. A) Ozone Monitoring Instruments Ozone Concentrations in the Stratosphere Source: Earth System Research Laboratory, 2012, Viewed 07.06.14, http://www.esrl.noaa.gov/gmd/dv/spo_oz/spototal.html A) Analysis of Trends There are a variety of trends that can be interpreted from the above diagram. Based on the data above, before the 1980’s, the total ozone concentration was VERY high, at approximately 194 DU (Dobson Units), however there was a very rapid decrease in this concentration from 1980 – 1999, whereby in this 19 year period sees a 56% decrease in the amount of total ozone, a remarkably concerning figure. On a year round basis globally, total ozone concentration have caused a 3-8% decrease in the amount of ozone, this increased in the years between 1995-200, where there was a low of total ozone concentration. However, in more recent years, 2010 to 2014 there has been a general increase in total ozone concentration, which can be inferred from the replacement of CFCs finally starting to impact (slightly) on the total concentration of ozone, this increase based on the data is 31%. The general pattern is that the total column ozone decreases during spring time, it can be inferred that the overall concentration of ozone decreases during this time of the year. This is because in an Antarctic winter, there is no U.V light to convert the chlorine molecule Cl2 into a Cl radical, which then destroy ozone molecules, and thus the concentration of ozone is higher in winter. In spring, the U.V light converts the Cl2 into Cl which then destroys ozone in a chain reaction, thus decreasing the total ozone concentration There are various peaks in the graph, in the years of 1988, 2003, 2011 and 2013, which may be due to limitation so of the instruments used. B) Montreal Protocol Effectiveness The Montreal protocol occurred in 1987, which the main aim was to control the production of ozone depleting substances (CFCs) worldwide. A number of amendments have been adopted to further ride ozone depleting substances. The protocol is applied in 193 countries. The main aims of the original agreement is as follow: Halt the use of Halons by late 1994 By the early 21st century, phase out the use of HCFCs Stop manufacture of CFCs by 1996 Allow for leeway with less developed countries but still get them to rid the use of these substances The Montreal Protocol (and amendments) has been effective as by 2006, the consumption of ozone depleting substances has been reduced globally by 96%. However, due to the long lives of the previously used ozone depleting substances, the total concentration will take hundreds of years to be completely down. However, the total concentration in the troposphere has generally been declining since the mid-1990s.
