In Asthmatic Children under the age of 5yrs is spacer inhaler more Essay

In Asthmatic Children under the age of 5yrs is spacer inhaler more beneficial than a nebulizer - Essay Example The recent British thoracic Society Guidelines (20) support the use of spacer inhaler over the nebulizer. The possible advantages that accrue include reduced cost of acquisition and operation, greater potential convenience and reduced incidence of infection. It is therefore very important to asses whether spacer inhalers are beneficial in children with with extremely asthmatic episodes. The above clinical question and the suggested intervention measures are relevant in clinical practice of our modern society. C- Comparison interest: indicate that nebuliser too can offer convenience depending on the prevailing situational circumstance in relation to time, cost and available staff training and level of professionalism. Search for the articles relevant for this research review was computer based. Article database search was based on the PubMed directory. An updated PubMed search (8 April 2013), with the key terms â€Å"asthma† â€Å" spacer†, â€Å"nebuliser verses spacer inhaler†, â€Å"asthma spacer inhaler†, â€Å"spacer nebuliser comparison†, â€Å"acute asthmatic children†, â€Å"or asthma with the key term limit of meta analysis, human, all children 0-5 years.

The new article obtained from the secondary search show a considerable compliance and correlation of the primary sources. They

Love Is All About Sacrifices Essay Example for Free

Love Is All About Sacrifices Essay Love encourages people to sacrifice important things in their lives for others. Love can destroy or improve ones’ life. It once happen to a little country girl in the early days. Love totally changed her life both destroying it and improving it. This girl’s name was Kat and she was the mayor’s daughter who was advised by her father to marry a guy named Bruce. Bruce was kind of a nice guy, really successful, but very serious and didn’t have no time to have fun. He was very well liked by the whole town and all the girls went crazy when they saw him. Everyone thought it was a great idea if they got married. Although, on the other hand, Kat was a girl very high spirited and she had fun all the time. One windy and cloudy afternoon, Bruce asked Kat’s hand in marriage while talking to her father. Kat’s father was very happy about the news that he announced the request to the whole town. Kat rather seemed â€Å"okay† about the whole situation instead of being excited. That night she had a dream about a dart in a board spinning over and over again but instead of the spinning making her dizzy she was happy. It was a really strange dream and it kept repeating three nights in a row. Contrary to her strange dream, she went to seek advice from her grandma who was probably about 94 years old. She was so excited to see her granddaughter and listen to her. â€Å"I had a dream grandma, a very strange dream and I need you to tell me what you think it means† she said. â€Å"I’m all ears† said grandma. â€Å"Let’s hear it†. She explained the whole dream to her grandma and said â€Å" so what do you think it means? † Asked Kat. Grandma said â€Å"pumpkin this dream means you should follow your heart and instinct because something important is about to happen in your life†. With excitement she said â€Å" oh grandma, I love you, you always have answers to every question†. â€Å"That’s what I do†. So Kat decided to head towards home. On her way home she noticed a conveyance truck or moving truck parked in front of an old house. Due to curiosity, she neared and watched what was happening there. To her amazement, she saw a handsome spirited young man who was admiring the building. She asked â€Å"are you new in the neighborhood? † â€Å"Yeah I am, anyway I am Jason†. She stared at him for a while before answering† oh, I am Kat the mayor’s daughter and it’s nice to meet you† she finally said. I have to go, so I guess I would be seeing you around† she said. â€Å"Yeah â€Å"he answered. She looked so happy and relaxed on her way home. At her arrival at home her dad wanted to talk to her about Bruce but she said she didn’t like Bruce and wouldn’t marry him. Her father tried to convince her but she didn’t want to talk about it. The next day she went spying on Jason, she would get up early, go hide behind the house hoping to see him. This continued for many days until her best friend Tatiana followed her one day and found out she was spying on the â€Å"new guy in town† as she referred Jason to. During one morning, Tatiana went over to Jason’s house and told him all about what Kat did every morning. So he hid behind the house waiting for Kat to come. She did and was caught by Jason. He explained to her how he knew and that he also likes her but doesn’t spy on her behind her house every morning. Surprisingly, they started to go out for months during which Kat’s dad kept haunting her to marry Bruce. Six months later, they both expressed their feelings and decided to tell Kat’s dad that they are getting married. To their dismay , Kat’s dad did not agree with their decision and refused to give them his blessings. Out of love for Jason, Kat decided to leave her dad and the town to go get married to Jason in a different town or country. Before leaving she thanked her best friend Tatiana for being there for her and helping her. Also she invited her to be the brides maid at her wedding. Without her father’s acknowledgement she left the town, got married and had kids. Then he realized how happy his daughter is and began to regret not being there for her. So life can be real hard or easy but it all depends on the decisions made in our lives. Sacrifices made in our lives can result in pain or happiness. We should be wise and always make the right sacrifices!

Analysis Of The UV Visible Spectroscopy Biology Essay

Analysis Of The UV Visible Spectroscopy Biology Essay Purpose of this term paper is to describe working principle, instrumentation, data collection and data analysis of the UV-Visible spectroscopy which is also known as electron spectroscopy. In working principle, Beer-lambert law correlate absorption of light to concentration of substance in solution. Parts of UV-Visible spectrometer have been described. Data analysis and data collection section describe how data collected by system and what type of information we can get from the data collected from UV-Visible spectroscopy. In the end we conclude what we learn from the project. Introduction: In spectroscopy, matter is been exposed to radiative energy (light, high energy electron, high energy ions etc.), at that time it can interact with matter according to atoms or molecule are present in system. Depending on its interaction with material gives different information about the matter. In short, spectroscopy is the study of the interaction between matter and radiated energy. Absorption, emission, elastics scattering, inelastic scattering are major interaction between radiative energy and matter. In absorption, radiated energy is absorbed by matter. In emission, electron will excite and goes to higher energy level, then when it goes to ground state it will emits electromagnetic waves. When electron and radiative energy interact, but they dont exchange energy, this type of interaction are called elastic scattering, and if electron and radiative energy exchange energy, then this type of interaction are called nonelastic interaction. The selection of the spectroscopy to analysis the sample is depending on what is present in the sample. For example, if atoms of sample are targeted to analysis, X-ray spectroscopy and XRF (X-ray fluorescent) are useful. If molecules of sample are targeted to analysis, Infrared, Raman, visible, UV-visible spectroscopy, and fluorescence spectroscopy are useful. Raman and Infrared spectroscopy are complementary to each other. Same way, UV-visible spectroscopy is complementary to fluorescence spectroscopy. UV-Visible spectroscopy usually used for quantitative analysis of different molecule like transition metal ions, highly conjugated organic compound, and biological macromolecule. UV-Visible spectroscopy use UV light and visible light for analysis of sample. Range of Visible light is 400nm to 800nm. Where UV light has range from 400nm to 200nm which usually used in spectroscopy. Energy associate with 800 nm visible light is 36 kcal/mole. Energy associated with 400 nm visible light is 72 kcal/mole. UV light used in UV-Visible spectroscopy is up 200 nm because smaller then this range it is difficult to handle. So, UV light which has energy less than 200 nm doesnt use frequently. UV light which has wavelength 200 nm, energy associated with it is 143 kcal/mole. Figure 1: Energy band diagram of molecule here it shows HOMO and LUMO (bonding and anti-bonding) energy level Figure 1 is showing general energy band diagram which has energy level HOMO (highest occupied molecular orbital), LUMO (lowest unoccupied molecular orbital). HOMO is also known as bonding energy level. And LUMO is also known as anti-bonding energy level. In this diagram, shows some exciting possibility in molecular electron from lower energy orbital to higher energy orbital. However, from UV-Visible spectroscopy, electron gain only enough energy to excitation from à Ã¢â€š ¬ (bonding) to à Ã¢â€š ¬* (anti-bonding) energy level or from n (non-bonding) energy to à Ã¢â€š ¬* (non-bonding) energy level. For other excitation, it will require even higher energy that UV or Visible light can provide. So, using UV-Visible spectroscopy we can measure first two left hand sides to excitation from diagram. UV-Visible spectroscopy is also known as electronic spectroscopy because it measure absorption of light by electron. When sample molecules are exposed to light having an energy that equals a possible electronic transition within the molecule from HOMO to LUMO, some of the light energy will be absorbed as the electron is promoted from lower energy à Ã¢â€š ¬ orbital to a higher energy orbital like à Ã¢â€š ¬* orbital. An optical spectrometer records absorption at each wavelength and present as graph of absorbance vs. wavelength. Range of absorbance ranges from 0 (no absorption) to 2 (99% absorption) calculate by spectrometer. Here in UV-Visible spectroscopy, Beer-Lambert law has been used to find concentration of absorbing solute in the solution. When a light passes through a solution, due to interaction with material some of the light might be absorbed and the remaining light transmitted through the solution. The ratio of the initial intensity (entering the sample (Io)) and final intensity (exiting the sample (It)) of light at a certain wavelength is defined as the transmittance (T). Most of the time it has been expresses as percent transmittance. And the absorbance (A) of a sample is the negative logarithm of the transmittance. Equation : Beer-Lambert law which correlate transmittance to initial intensity and final intensity Equation : Beer-Lambert law which correlate Absorption to transmittance Here, Io is initial intensity (entering intensity) and It is final intensity (exiting intensity), T is transmittance, A is absorption. The absorbance of a sample at a given wavelength is equal to the absorptivity of the substance, path length and concentration of the substance. Value of the absorptivity of the substance depends on the wavelength. For different wavelength, value of the absorptivity is different. The path length is the distance the light travels through the sample. Equation : Beer-Lambert law which correlate absorptivity, path length, concentration of substance Here, is absorptivity of the substance, l is path length; and c is concentration of the substance. Commonly, and l are constant for experiment because depending on material is fix value and experiment length of path (l) is also fix for each experiment. So, using these equations we can calculate the concentration of substance in given sample. Instrumentation: Figure 2: Working principal of UV-Visible spectroscopy [3] Ultraviolet (UV) and Vis light spectroscopy has been shown is figure-1. This device contains UV light source and visible light source, slits, Diffraction grating, filters, mirrors, reference cuvette, sample cuvette, lenses and detectors. Light source: This device has two light sources. Depending on the sample either UV or Visible light source will be used. Using Mirrors light will be concentrated on Diffraction gritting. Usually UV light source has range from 200nm to 400nm, and visible has range of 400nm to 800nm. For UV light source, Hg bulb is used. And For Visible light source, Tungsten is uses. Diffraction gritting and filter: Diffraction gritting converts light source into its component wavelength light. Prism can be used instead of diffraction gritting. Then Created single wavelength light is given to half mirror Half mirror: Half mirror is special kind of mirror which can provide two same intensity output from single input sources. In our device, it will be used to provide same intensity single wavelength light to the reference cuvette, and sample cuvette which contain only solvent. Solvent can also interact with the sample. So it is necessary to measure light interaction with solvent which later can be remove from sample which contain solvent and solute to measure light interaction with solute which is area of interest. Reference Cuvette and Sample Cuvette: In UV- Vis spectroscopy, it is very important to compare intensity to get transmission. Light is passes through the both cuvette. Absorption is done at this stage; level of absorption will depend on the sample and the reference themselves. Lens and Detector: Lenses will be used to focus and magnify the output reference beam (I0) and output sample beam (I). Here I0 should be absorbed just little Detector will be used to detect these signals and convert into electrical signals which can be further understand using software and computer. Figure 3:   Shimadzu 1650PC, UV-visible Spectrophotometer. [2] Data Collection [4] [5]: Instrument was SHIMADZU UV 1601. Absorption of liquid and thin film can be measured by this instrument. Liquid Sample For liquid or solution, cuvette is used. It is required reference solution containing cuvette, and sample containing cuvette. In reference cuvette, it will have only solvent. Using this data, absorption for cuvette and solvent can be understood. Using data of sample containing cuvette, absorption for cuvette, the sample and solvent can be understood. Surface of cuvettes must be cleaned after filling the liquid to make sure surface does not have any dust particles. Using software, Method is needed to be defined. In our Method, wavelength range is 300 nm to 1100 nm; scan speed is medium; sampling interval is 1 nm; scan mode is single. A 1st need to do is measure reference (baseline, solvent only). It is also important that reference cuvette is inserted in reference stage not in sample stage. Mounting of cuvette is very important. Cuvette has two types of surface. Cuvette has two transparent sides and two semi-transparent sides. Transparent sides need to be aligned so light beam can enter and exit from transparent sides. Load the reference sample. Define wavelength range (1100-300nm) scan in software. It will take about 2 min to finish scan for reference. It is also important to do it reference scanning process again if you change the type of the sample, cuvette or solvent. Secondly, low concentration seldibrdge (2.9*10^-6 mole/L) chromophore sample will be loaded in another cuvette and it will be loaded in to sample stage. In software, start scanning button is clicked. Scanning of the sample will also take about 2 min. When scanning is finished new window will appeared and will ask for file name and file description. Now on screen you will able to see typical graph absorption spectrum of seldibrdge chromophore. Computer will assign some peaks. To access this information peak button on screen will be pressed. After that computer will provide table which include Wavelength and Absorption. This table and concentration of the sample is useful to calculate extinction coefficient or molar absorptivity. This calculation will be done by Beer-Lambert Law. Third, high concentration seldibrdge chromophore (2.9*10^-5 mol/L) sample will be loaded in another cuvette and it will be loaded in to sample stage. Concentration is almost 10 times more than low concentration. It will be loaded in to sample stage. In software, start scanning button is clicked. Scanning of the sample will also take about 2 min. Data can be stored by using Data Print Table extension and it will information in notepad. Thin film Sample is dissolved in polymer matrix and applied on glass substrate. For this process, glass substrate is used as sample. It is very important to not to touch surface of the glass substrates. It is also required to make sure it does not have any dust particles on it. Then load reference sample in reference stage and press baseline button on computer screen. After that, sample is put on sample stage. It is important to orient the sample surface side, so light can directly interact with thin film first rather than glass substrate. Then press start on computer screen. Data table and Spectrum chart will be provide by computer. Data can be saved as the above description. In thin film, concentration is unknown, so extinction co-efficient cannot be calculated. For thin film maximum absorption is important factor. Data analysis: Chromophore is part of molecule which is responsible for its color. So, during UV-Visible spectroscopy electrons in chromophore are interacting with light. Table 1 is giving data about different chromophore. Chromophore may be present in solvent. So, we require selecting proper solvent to measure chromophore of solute. Not all the solvent can be used in UV-Visible spectroscopy. For example, oxygen non-bonding electrons in alcohols do not give rise to absorption above 160 nm. So, we can use as solvent for UV-Visible spectroscopy. Common solvent can be used in UV-Visible spectroscopy are Hexane (alkane), ethanol (alcohol), water. However, if we used UV light which has wavelength are lower than 200 nm, then we cant use alcohol because it create very sharp peak.

As describe in introduction, using transmittance, we can calculate concentration peak. However, all the data in computer give form of absorbance vs. wavelength or Ɇº vs. wavelength. Sometime value of log Ɇº is taken in place of Ɇº. There are some graph obtain from UV-Visible spectroscopy. Both Ɇº (molar absorptivity) and A (absorption) are changing with different wavelength. Figure-4 is absorbance vs. wavelength graph for C5H6O. Figure 5 is graph of Ɇº vs. wavelength for different conjugate compound which has same chemical formula. In graph, each peak represents a certain excitation. Figure 7 shows two different excitation, first excitation is from à Ã¢â€š ¬ to à Ã¢â€š ¬* and second excitation is from n to à Ã¢â€š ¬*. Both excitations have pick value at different wavelength. For excitation à Ã¢â€š ¬ to à Ã¢â€š ¬*, maximum Ɇº value is around 250 nm. And for excitation n to à Ã¢â€š ¬*, maximum Ɇº value is around 300 nm. From figure 5 and 6 we can say that as number of Chromophore, curve shift to longer wavelength; however number of picks doesnt change if Chromophore is same. However, for aromatics compound, as ring increase, number of pick are increasing. Due to different Chromophore present in molecule, it will effect on maximum absorption wavelength. There different terms are assigned for different type of shift which can see in table 2. Figure 4: UV-Visible spectroscopy results for C = C and C = C Chromophore for particular chemical compound at specific pH, and solvent. [1] Figure 5: UV-Visible spectroscopy results for conjugated compound. [1] Figure 6: UV-Visible spectroscopy results for conjugated compound [1] Figure 7: UV-Visible spectroscopy results for C = C and C = O Chromophore for particular chemical compound at specific pH, and solvent. [1] pH of system is also effect on absorption peak. Diluted Copper sulfate solution is very light blue. However, if you add ammonia which will change pH more than 7, color of solution will change due to change in absorption peak and intensity. Following figure 8, is UV-Visible spectra of phenolphthalein at different pH value.

Table 3: Wavelength and absorption for low concentration Liquid seldibrdge chromophore, concentration. [4][5] For higher concentration liquid seldibrdge chromophore, concentration is 2.9*10^-5 mol/L. Absorption of this sample is out of spectroscopy range. So it is required to dilute for further understanding and calculation. For unknown concentration of seldibrdge chromophore dissolved in polymer matrix and applied on glass substrate, concentration is unknown, so further calculation of extinction coefficient cannot be done, but peak absorption can be find. For this sample peak absorption is 0.512 at 808 nm wavelength. Using equation 3, we calculated Ɇº (extinction coefficient or absorptivity) is around 2.1E5 1 / M * cm at maximum absorption. Conclusion: UV-Visible spectroscopy is good for finding concentration or molar absorptivity of of biological macromolecule, organic molecule, transition metal, conjugated organic compound.. However, we need to make sure about pH of system and solvent before taking sample analysis. Using this spectroscopy, we find molar absorptivity or extinction coefficient of 2.9*10^-6 mol/L concentration Liquid seldibrdge chromophore for maximum absorption at given wavelength.

The Wedding of Sir Gawain and Dame Ragnell :: Dame Ragnell Character Analysis Essays

The Wedding of Sir Gawain and Dame Ragnell In the story of "The Wedding of Sir Gawain and Dame Ragnell," we are introduced to a rather interesting character, Dame Ragnell. We meet Dame Ragnell in the beginning of the story when King Arthur is riding his horse into Ingelswood Forest. He then meets a lady, Dame Ragnell, who is described to be absolutely hideous and grotesque. The story gives a complete description of this old, foul woman: Her face was red, her nose snotid withalle, Her mouithe wide, her teethe yallowe overe alle, With blerid eyen gretter then a balle; Her mouithe was not to lak; Her teeth hing over her lippes; Her cheekis as wemen hippes. Dame Ragnell is a repulsive creature. She's described as a big, broad-shouldered woman with yellow, rotten teeth hanging over her mouth, great big eyes, and a big red face with cheeks the size of a lady's hips. King Arthur runs in trouble and is given twelve months to find the answer to the question, "What do women most desire?" With his life riding on this answer, King Arthur desperately asks Dame Ragnell to tell him what women most desire. She tells him that women most desire power and sovereignty in marriage. But she tells him this only after he promises that one of his knights, Sir Gawain, will wed her. Sir Gawain does indeed marry her, but only because of his strong loyalty to his king. Sir Gawain is disgusted by her appearance, but he knows this is the only way to save King Arthur. People pity Sir Gawain, a very handsome man who possesses nobility and honor, for having to marry such a loathly woman. Dame Ragnell has no manners, especially at the dinner table. When she feasts at King Arthur's court, she eats as much food as six grown men: Her nailes were long inchis three; Therewithe she breke her mete ungoodly; Dame Ragnell's appearance is the result of her stepmother's wicked spell. Her stepmother cursed Dame Ragnell many years ago and the spell can only be broken if she weds a man who gives her sovereignty in their marriage. The spell has yet to be broken†¦that is until she is married to Sir Gawain. Then, she gives Sir Gawain the ultimatum that he can either choose for Dame Ragnell to be beautiful during the day for all men to admire, and at night she will be ugly for Sir Gawain, or for her to be ugly during the day and beautiful at night for Sir Gawain to enjoy.

tempmagic Magic in Shakespeares The Tempest :: Tempest essays

Magic in Shakespeare’s Tempest The Tempest, written in 1611, was one of William Shakespeare's last plays. It has a combination of superb characters, interesting settings, and a good plot line—all held together by the running theme of magic, and its ever- present importance. A closer examination of the magic in The Tempest, and the public's view of magic at the time, will give insight as to Shakespeare's choice of magic as a theme, and why it has made the play so successful and timeless. Magic presented itself to Shakespeare as a controversial topic, as it had been the persecution of those believed to perform "black magic," (witches) that had been at the forefront of societal concerns since 1050. However, after 500 years of witch-hunts, a turning point occurred in 1584, at the publication of Reginald Scot's The Discouerie of Witchcrafte (The Discovery of Witchcraft). This book was the first major book to denounce witch-hunts and their ringleaders, and unquestionable the first book in English to actually hypothesize about the methods of these so-called witches. It contained one chapter of approximately twenty pages describing what we might view as unsophisticated, old-time magic tricks. One would assume that it was this text, and texts succeeding this (The Art of Juggling, written by Samuel Ridd in 1610 also presented a few how-to's of magic) were probably not only what suggested the idea of using magic as a them to Shakespeare, but in addition, provided methods as to how the magic in the play might be accomplished. Despite the fact that in retrospective analysis it is fairly clear that witches were nothing more that magicians with a slightly different presentation, audiences were not always aware of –and those that were, were rarely convinced by—the two aforementioned texts. Witches were still persecuted and witch-hunts did not actually stop until the end of the seventeenth century. Therefore, Shakespeare's use of magic was controversial, compounded by the fact that Prospero was presented in a largely good light—a move probably made as a political statement, as it is known that Shakespeare's plays were sometimes written to include political suggestions to King James. However, when Prospero relinquished his powers at the end of the play, those that did believe in the witch-hunts were satisfied. Everyone was happy. After considering the contention that the masque scene was added for the purposes of compliment to Elizabeth and Frederick's marriage, one could conclude that Shakespeare learned more about magic after he wrote The Tempest. The reasoning follows. One could only assume that Shakespeare would have tried to make the magic in the play as fooling and magical as possible. tempmagic Magic in Shakespeare's The Tempest :: Tempest essays Magic in Shakespeare’s Tempest The Tempest, written in 1611, was one of William Shakespeare's last plays.

Human Cloning - Individualistic vs. Communitarian :: Cloning Argumentative Persuasive Argument

Human Cloning - Individualistic vs. Communitarian In many controversial topics around the world, we can find differing positions, and opinions. Many of these arguments, can be narrowed down to two different views, or constructs: individualistic and communitarian (an image of collectivism). An individualistic viewpoint "stresses the rights of the individual as a unique being" (class review). A communitarian viewpoint is more concerned with the good for the greatest number, "even if an individual must suffer or sacrifice" (class review). These different elements do not necessarily label the people as opposed to, or in favor of the topic here. They just show where your motivations lie, is your involvement for self fulfillment or for the good of society? Within the contents of this paper, I will analyze the elements of individualism and collectivism that exist in the controversial topic of cloning. When Dr. Ian Wilmut, a 52-year-old embryologist at the Roslin Institute in Edinburgh announced on that he had replaced the genetic material of sheep's egg with the DNA from an adult sheep, and created a lamb (Dolly), the topic of cloning "created" many new questions of its own. None were as controversial as: Will they apply this to humans as well? According to Dr. Wilmut, the answer was "there is no reason in principle why you couldn't do it"(clone humans), but he added, "All of us would find that offensive."(Wilmut as quoted by NYTimes, Daniel Callahan, 02/26/97). From an individualistic viewpoint, those in favor of cloning human beings, do not see it as morally, or ethically wrong. Many see it as an opportunity to have children, or possibly to "re-create" a child who is dying from a terminal illness. Using a deterministic argument, many infertile couples are worried that any "government restrictions on human cloning might hurt their chances some day for bearing children through new medical technology" ( Newsday, Thomas Maier, 03/14/1997). In a form of expressive individualism, Tom Buckowski, from Studio City, California said, "It's my body, my choice, right? But what if I want my body cloned and warehoused for spare parts? Upon what basis can government decide what I can or cannot do with my body?"(Los Angeles Times, 3/07/1997). In both examples, the predominant voice is that of the first language of individualism. The first language refers to the "individualistic mode that is the dominant American form of discourse about moral, social, and political matters" (Bellah et al, Habits of the Heart, pg.334). Anita Manning, a writer for USA TODAY revealed another individualistic argument in favor of cloning. In her article "Pressing a "right" to clone humans," Manning interviews a group of gay activists, who see

It was 9 o’clock in the morning when I heard the news that Aliens were going to invade our planet

It was 9 o'clock in the morning when I heard the news that Aliens were going to invade our planet. As unlikely, as this sounded, I knew it to be true the moment I heard it. I had already seen the evidence. Please excuse me; I guess I am rushing ahead a bit. It would probably be better if I started from the beginning. It started 10 months ago when I was working at the Jodrell Bank radio telescope. I was a scientific researcher at the base; and a specialist in radar research. Some of my colleagues had been getting weird results from their observations and I had been asked to double check the validity of their findings. These weren't the only weird happenings either. Scientist from different parts of the planet researching both climate and animal behaviors were also reporting a wide variety of anomalous data. The climate was changing, there were resent reports that a tornado struck the south-east of England. That wasn't the only weird occurrence in weather that had happened; a few weeks later there was another report that a snowstorm had hit West Africa. Alongside all of this there had been rumors of country leaders having meetings discussing the strange events that had been happening. Occurrences after occurrence still leaders around the world were making up lies and excuses, over 100 nuclear power plant had been struck by lightning and earthquakes spontaneously. Haunted by all of these occurrences and happenings, I found it hard to sleep. Even when I could sleep, I was disturbed by weird recurring nightmares. Still, my research work was proving to be equally unsettling. No matter what test I performed, I could find no data that would allow me to dismiss the results drived by my Colleagues. As these findings indicated many anomalous objects were present in near-near Earth orbit. I found myself called in to the office of observation director himself, and as I looked through the images that the Hubble telescope was giving me I noticed weird looking objects that were hovering Earth orbit, by the time I could show the images to my head director we were quickly stopped and ordered to leave the premises. While I tried to go back to get the images as prove I was immediately stop and guided outside of the building. After that incident I was sent home, I had a conversation with my head director telling me that the workplace was being closed for illegal experimenting. The government closed Jodrell bank Telescope and announced that we had secret bases. I worked there for 13 years and had never encountered any secret bases were experiments were performed. Why did the government really close my workplace? Day after day I started to realize that my colleagues were rapidly but slowly losing contact. Until one morning when I was mysteriously called by one of my colleagues to watch a broadcast acknowledging the existence of other life forms and their invasion of our planet. While listening to the event, I suddenly thought †why has the news turned black? †I thought that they were having technical difficulties so I changed to the next channel and when I did it turned out the same as the channel before. The whole screen just plain black while. At the same time, I was confused, a bright light made me cover my eyes, and a shape appeared with the way it spoke. I knew it to be a face but it wasn't a recognizable face and one that I have never encountered. The shape and figure of the life form was unforgettable. It breathed softly and spoke gently. I understood: â€Å"People of earth, we are concerned that your world leaders have been dishonest and created your worst nightmares, bringing destruction and violence upon you. I will give you your last choice of renewing and establishing the disturbance you have caused. I couldn't believe what I was hearing; we were so loud that we caused concern upon our cosmic neighbors. They had taken us as threat to the galaxy. This is one big step for human beings.
