Lab Report Example in feeding as it has different mouth parts and mainly feeds on nutrients whereas the adult is specialized in the process of reproduction and dispersal. The type of food consumed between the larva and the adult is entirely different, and this, therefore, enhances their survival. The adult has the secondary characteristics of flying, walking and crawling and therefore even the type of diet it consumes is entirely different from the larva (Kay 3). The organism had both the crypsis and aposematism coloration as a defense mechanism. In crypsis, as exemplified by Kay, 1969, the camouflaging is as a result of the background as was evidenced in the experiment. The phenotypic aspect of the organism in terms of behavioral change in the environment must come into play before coloration occurs. The aposematism effect referred to as warning coloration was observed when there was a striking contrast in terms of background color. The organism died after a period of two weeks as a result of exposure to direct heat from the sun. This in turn led to the destruction of the newly formed chitin that could have provided the protection of the internal organs. The presence of chitin is vital in the life of the organism as this feature offers protection and helps in reproduction through molting process (Kay 5). The death of the organism may result due to different reasons. For instance, improper feeding or harsh environmental conditions minimizes their chances of

Green Energy - How will green energy technology prove to overcome the Research Paper

Green Energy - How will green energy technology prove to overcome the challenges of providing energy to the world - Research Paper Example Man will devise ways to substitute the materials endangered by exhaustion like fossil and nuclear energy sources, with renewable energy sources. Renewable energy will continue to combat â€Å"greenhouse gas emissions within the power sector† (Moselle, Padilla and Schmalensee 160). This paper discusses important sources of green energy, and why these sources are known as renewable sources of energy. First of all, it is important to describe the types of renewable energy sources. Sun power, wind power and water power are three main sources of green energy. Sun power produces solar energy, and is a very powerful form of energy. It has been there since ages, and will remain there till the end of the world, providing heat and light energy to all forms of lives- animals, plants and humans. Solar energy is called renewable energy due to a variety of reasons. First, when modern technological methods convert solar energy into electricity, no smoke is produced. So, there is no production of carbon dioxide and other toxic chemicals in the air. Also, the supply of solar energy is not limited, so, there is no worry about running out of energy. However, solar power cannot always be relied upon, as there is no sun in the night or in cloudy weather. Solar cells and solar panels are two main devices that convert solar energy into electrical energy. Solar cells, also known as photovoltaic cells , are found in smaller devices as calculators, and are also used for bigger purposes like in road signs. Solar thermal power plants and the parabolic trough systems are modern technological methods that use solar panels that trap in sun power to heat up water that, in turn, produces electrical energy. Another source of renewable energy is water, called hydro-power. Since water in motion produces kinetic energy, this scientific fact is used by hydro-electric power

Why we should not legalize marijuana Research Paper

Why we should not legalize marijuana - Research Paper Example In response, the federal government holds high profile meetings relating to the decision (Savage 1). Besides the conflict, there are a number of problems likely to emerge when states continue to pass legislations that allow marijuana use. With the growing influence from lobby groups in support of marijuana legalization, as predicted by opinion poll results, public education is vital. The public needs to understand the reasons why the drug should remain illegal before going to polls. In as much as marijuana legalization proponents present a picture of a safe society that freely smokes, there are credible reasons to outlaw the drug and impede efforts to legalize its use. Supporters of the legalization of marijuana foresee their supporters smoking freely after uplifting laws that ban marijuana while they assume that the federal government shall remain strict on drug. This presents the challenge of a conflict that states shall experience regarding their contradictory laws and policies on the use of marijuana. There is a serious need for coordination between federal and state governments to evade differences as those experienced in keeping law and order. Ultimately, the citizens are borne to bear the consequences of such contradicting laws. It is noteworthy that citizens are the proponents of regulations and policies that are most likely to affect them. Court rulings on cases involving marijuana trade and possession shall differ, for instance. This places the justice to the citizens at stake and considerable challenge to the society. Since the federal courts have the final say over state courts, marijuana laws shall remain illegal despite its legalizat ion by some states. Eric Holder, the American Attorney General, is on record reiterating that the federal government will launch relentless efforts to prosecute anyone who demeans the law by using Marijuana, in the country.

And when I begin to ask my parents about forefathers I find for myself a lot of interesting things. For example some features of character which I have or part of appearance. But it’s a pity that I know not a lot of people in my family branch.

The Use of Creatine in Sports Essay -- Athletics Steroids Drugs Sports

The Use of Creatine in Sports The first weeks of my senior season of football were the toughest times I had ever had in my life. We had two practices a day. We had one practice early in the morning, and one late in the afternoon. Physically, I wasn't at a level like most of my teammates. I felt like I couldn't do anything on the high school level; plus I was being thrown around like a rag doll. I needed something that would help me reach my potential. That's when I tried creatine. I started out taking small doses of creatine as an energy booster before practice, noticing that I wasn't getting tired and out of breath like I once was. I continued to use the supplement before I did any type of exercising activity, although I never exceeded the daily amount. I used the supplement for about three weeks, noticing muscle development and body fat loss all over my body. Gradually, I started reducing my dose each day until my supply was gone. In my short three weeks of taking creatine, I gained about 4-5 pounds of lean muscle. I was being noticed in practice and was getting more playing time in games. I was still unsure about what consequences I would have to face if I continued to use the substance. I needed to know more. Everything has a price; l wanted to figure out what mine could be.   Ã‚  Ã‚  Ã‚  Ã‚  It's been called the drug that separates the great from the greatest. It has helped athletes all over the world reach their potential. Creatine is an all natural food and supplement drug that works like anabolic steroids without the side effects. It has the capability to help produce muscle mass, energy, and speed all in one pill. Over the past few years, creatine has become a controversial issue in the athletic world. A lot of research has been put into creatine although long-term effects are left unknown, leaving the controversial question of whether creatine should be legal or illegal. Being a former user of creatine showed me how I could maximize my potential athletic ability, although leaving me cynical about harm to my body. I wanted to know more specifically how it works on the chemical level and major side effects and precautions I should take if I were going to continue using the supplement. The only way for my to find the answers to my questions was with research.

Speech Recognition Software :: Essays Papers

Speech Recognition Software Throughout the past 100 years, we have had visions of what the future would be like thanks to the creative minds behind movies and television shows. Many predictions as to what the future would be like have come true, while others are still far off. One element that can be seen in almost all futuristic fictional forms is that of speech recognition. Right now, developers are hard at work trying to make speech recognition an aspect of every day life. It is far from this final destination, but that’s not to say it isn’t a technology that is being used today. Several elementary products are available now that utilize speech recognition software technology. Speech recognition is a revolutionary technology in software development that will change the way we interact with our digital world. Speech recognition has been created and researched for many valid reasons. The main purpose of the technology is a way for humans to interact with computers and other digital devices by simply speaking. They can not only tell the computer commands, but they can speak normally while the computer converts the speech into text. This improves input speed to the computer because a person can speak much faster than they can use their hands typing or controlling the mouse. This is also an advancement that helps people with disabilities (Connections). People with arthritis, weak bones, or other medial conditions may have a hard time typing and using the mouse. Blind people can’t even see computer screens to check for spelling mistakes or to see where the mouse cursor is on the screen. Speech recognition can help these disabled people interact with computers in ways that were previously impossible. The software itself does most of the work, and the user essentially only has to speak at the speed the program can operate. There are a few different types of voice recognition software, all programmed to interpret a vocal signal inputted by the user. In order to use the software, the user must use a headset or some other microphone-type device that allows for vocal input. The technology works as follows: the analog signal from the voice cones in through the microphone, that signal is converted to digital, and the voice software interprets the digital signal.

A Beautiful Mind Characterization and Dialogue

Writing Portfolio The 2001 biopic/drama film ‘A Beautiful Mind’, directed by Ron Howard is a prime example of a text in which visual and verbal techniques are used to develop the personality of a character. An important job for the director of any film is to establish a framework and personality for the protagonist. ‘A Beautiful Mind’ is no different, and visual and verbal techniques are used effectively to develop the personality of John Nash.But because Ron Howard is dealing with a very complex character in the form of a paranoid schizophrenic mathematician, his personality is forever changing and the differing film techniques achieve this. As this film is a biopic/drama drawn into one, the viewer follows Nash’s life over a number of years. Nash faces many tricky dilemmas and the way he deals with these situations are conveyed to the audience, using these film techniques. Nash (who is portrayed by Russell Crowe) changes drastically throughout the te xt, because he suffers from paranoid schizophrenia.Director Ron Howard uses the technique of ‘characterisation’ to adapt his personality in different ways. Throughout the text, the viewer is introduced to several ‘imaginary characters’, who are in fact delusional figures created by Nash. The first component of the ‘characterisation’ technique is when director Ron Howard chooses to introduce these characters. Often injected at great times of stress for Nash, the delusion characters normally create further dispute between Nash and his real life companions.An important stage of the text is just after the climax, where Howard chooses to include and remove Nash’s best friend Charles (in the form of the actor). Nash is preparing a bath for his baby son, while wife Alicia is outside tending to the washing outside. But because Nash suffers from schizophrenia, he is delusional and believes his friend Charles is watching the baby. For the viewer, all that is witnessed is the baby lying in the bath, crying it’s lungs out as water seeps over its head. Nash’s personality is developed negatively in this scene. For the viewer, Nash is developed negatively because of these delusions.The delusions put his baby sons life at risk, and also cause a further rift between Nash and his wife Alicia. In earlier scenes, Nash’s friend Charles was in fact present to the viewer in the form of the actor (portrayed by Paul Bettany). The effort to include the actor in these earlier scenes is a bid by the director to create the same realism for Nash, as for the audience. But in later scenes, the removal of Bettany and other cast members changes the viewer’s perspective of this protagonist. As the actor is no longer present, the viewer is forced to side with Alicia in thinking John Nash is delusional.The viewer here, is easily able to pin point the affects that paranoid schizophrenia has on Nash, and other sufferers of th at disorder. Characterisation is important, as in these later scene his personality is changed into a very confused man. The confident, charming and intelligent John Nash of Princeton University is instantly transformed personality due to the including and removing of key characters. These key characters not only include Charles, but also his niece Marcee and Special Forces Operative William Pacher. Dialogue is another technique (this time verbal) which is important in developing the personality of character John Nash.Director Ron Howeard opts to portray Nash as an arrogant and scornful outsider in the opening scenes of the film. During these stages, dialogue is crucial to develop this personality. â€Å"There must be some mathematical formula for how bad that tie is†, Nash statesto a fellow student on his first day at Princeton. While later, he criticises his co-recipient scholarship winner Martin Hansen by announcing â€Å"There isn’t one seminal or innovative ideaà ¢â‚¬  in either of his pre-prints. These quotes are just two extracts of dialogue from the early scenes of the text which develop this arrogant and scornful personality.As the text continues and his problems with schizophrenia are developed, the idea of Nash being an outsider is put in place. Another form of dialogue is important in the closing scenes of the text. Nash’s personality has transformed remarkably from his younger days. In his elder years, he is back teaching at Princeton. Nash is a much more mellow man in these scenes and dialogue is again used as a technique to develop this personality. After being nominated for the Nobel Prize, Nash concludes during his reception speech. â€Å"Perhaps it’s good to have a beautiful mind, but it’s an even greater gift to discover a beautiful heart†.This piece of dialogue is essential in reflecting the more mellow character that Ron Howard chooses to develop. In earlier scens, Nash is arrogant, scornful and p re-occupied to solve an innovative maths formula. Combined with his schizophrenia, this results in Nash being regarded as an outsider. In these times, he is greatly supported by his wife Alicia, as she deals with his mental disorder also. By Nash saying ‘an even greater gift is to have a beautiful heart†, proves that does identify the most important thing in life, which is his family.His eternal love for Alicia and their son, is more important than solving mathematical formulas, and his dialogue re-iterates this changed persona. No longer is Nash a scornful outsider, and his great love for Alicia (in which he again displays) is seen more favourably by the viewers of the text and develops a nicer personality of Nash. All respect to Russell Crowe, who portrays the life of a paranoid schizophrenic fantastically, it’s the crucial visual and verbal techniques implemented by the director that implement this. Nash’s personality is troubled and he is presented as d angerous during the bath scene with his son.By the removal of actors playing the delusional characters in the film, the viewer is truly able to see how disdurbed Nash is because of his illness. While the dialogue is unsed in the opening an clothing scenes to change Nash’s personality from an outsider, to a more open and affectionate man. Nash’s personality in the earlier scenes, is probably related to schizophrenia in general. People who suffer from the illness are often felt alone and compainionless. Ron Howard’s ability to truly reflect the persona of a PSD sufferer is important. In later scenes, Nash is drastically changed and no longer scene as an outsider.This transformed personality is the result of careful and meaningful dialogue in the test. This would relate to Nash being much softer in the closing scenes towards both his wide and the wider society he lives in. This re-iterates the importance of language techniques and how they can be used to show a cha racters position amongst a community. Nash who in the beginning is established as an outsider, becomes a much more balanced man , involved in the Princeton community. Dialogue is just one of these techniques used to develop the character of John Nash effectively.
