Brazil nuts reproduction ecological report Essays - Free Essays

Brazil nuts reproduction ecological report Essays - Free Essays Brazil nuts reproduction ecological report Dr. Alan Rizzo IB Biology SL Y1 January 13, 2014 Brazil nuts reproduction ecological report Brazil nuts contain exceptional nutritious elements and can only be harvested in the Amazon forest of Brazil. Each Brazil nut tree towers high up to 200 feet; its branches provide habitat and food for other animals. Despite the fact in which only those Brazil nut trees that grow in undisturbed forests bear fruit, their reproduction has high dependency on other organisms of the forest. In accordance to my research, there are two main organisms that every Brazil nut tree depends on for its own reproduction: the orchid Coryanthes vasquezii and the agouti of genus Dasyprocta. Only an insect strong enough to lift the coiled hood on the flower can pollinate Brazil nuts and with a tongue long enough to reach the complex flower spiral. Nut production depends on the presence of Coryanthes vasquezii, an orchid that attracts long-tongued male orchid bees of genus Euglossa, with its scent that male bees need to attract females. The large female long-tongued orchid bees then pollinate the Brazil nut trees. If there is no orchid, the bees will not mate, and the lack of bees means that Brazil nut trees will not get pollinated. Brazil nut fruits will take 14 months to mature after the pollination. Each fruit has a diameter of 10 to 15 cm and weighs up to 2 kg, which is called Ourio. Its shell, similar to wood, is 8 to 12 mm of thickness, and it has about 8 to 24 seeds, which are the Brazil nuts, inside. The agoutis, South American rodents that appear similarly to large guinea pigs, possess the ability to penetrate the hard-rock case of Brazil nut fruits. Their small and chiseled teeth crack open Brazil nut pods. They eat some of the nuts before burying them for future meals. When those nuts are forgotten, they stay dormant for years in nature before finding optimal conditions to germinate, and grow into a new Brazil nut tree.

Battle of Marathon in the Persian Wars

Battle of Marathon in the Persian Wars The Battle of Marathon was fought during the Persian Wars (498 BC–448 BC) between Greece and the Persian Empire. Date Using a proleptic Julian calendar, it is believed that the Battle of Marathon was fought on either August or September 12, 490 BC. Armies Commanders Greeks MilitiadesCallimachusArimnestusapprox. 8,000-10,000 men Persians DatisArtaphernes20,000-60,000 men Background In the wake of the Ionian Revolt (499 BC-494 BC), the emperor of the Persian Empire, Darius I, dispatched an army to Greece to punish those city-states that had aided the rebels. Led by Mardonius, this force succeeded in subjugating Thrace and Macedonia in 492 BC. Moving south towards Greece, Mardonius fleet was wrecked off Cape Athos during a massive storm. Losing 300 ships and 20,000 men in the disaster, Mardonius elected to withdraw back towards Asia. Displeased with Mardonius failure, Darius began planning a second expedition for 490 BC after learning of political instability in Athens. Conceived as a purely maritime enterprise, Darius assigned command of the expedition to the Median admiral Datis and the son of the satrap of Sardis, Artaphernes. Sailing with orders to attack Eretria and Athens, the fleet succeeded in sacking and burning their first objective. Moving south, the Persians landed near Marathon, approximately 25 miles north of Athens. Responding to the impending crisis, Athens raised around 9,000 hoplites and dispatched them to Marathon where they blocked the exits from the nearby plain and prevented the enemy from moving inland. They were joined by 1,000 Plataeans and assistance was requested from Sparta. Encamping on the edge of the Plain of Marathon, the Greeks faced a Persian force numbering between 20-60,000. Enveloping the Enemy For five days the armies squared off with little movement. For the Greeks, this inactivity was largely due to a fear of being attacked by the Persian cavalry as they crossed the plain. Finally, the Greek commander, Miltiades, elected to attack after receiving favorable omens. Some sources also indicate that Militiades had learned from Persian deserters that the cavalry was away from the field. Forming his men, Militiades reinforced his wings by weakening his center. This saw the center reduced to ranks four deep while the wings featured men eight deep. This may have been due to the Persians tendency to place inferior troops on their flanks. Moving a brisk pace, possibly a run, the Greeks advanced across the plain towards the Persian camp. Surprised by the Greeks audacity, the Persians rushed to form their lines and inflict damage on the enemy with their archers and slingers. As the armies clashed, the thinner Greek center was quickly pushed back. The historian Herodotus reports that their retreat was disciplined and organized. Pursuing the Greek center, the Persians quickly found themselves flanked on both sides by Militiades strengthened wings which had routed their opposite numbers. Having caught the enemy in a double envelopment, the Greeks began to inflict heavy casualties on the lightly armored Persians. As panic spread in the Persian ranks, their lines began to break and they fled back to their ships. Pursuing the enemy, the Greeks were slowed by their heavy armor, but still managed to capture seven Persian ships. Aftermath Casualties for the Battle of Marathon are generally listed as 203 Greek dead and 6,400 for the Persians. As with most battles from this period, these numbers are suspect. Defeated, the Persians departed from the area and sailed south to attack Athens directly.   Anticipating this, Militiades quickly returned the bulk of the army to the city. Seeing that the opportunity to strike the previously lightly-defended city had passed, the Persians withdrew back to Asia. The Battle of Marathon was the first major victory for the Greeks over the Persians and gave them confidence that they could be defeated. Ten years later the Persians returned and won a victory at Thermopylae before being defeated by the Greeks at Salamis. The Battle of Marathon also gave rise to the legend that the Athenian herald Pheidippides ran from the battlefield to Athens to announce the Greek victory before dropping dead. This legendary run is the basis for the modern track and field event. Herodotus contradicts this legend and states that Pheidippides ran from Athens to Sparta to seek aid before the battle.

International relations Essay Example | Topics and Well Written Essays - 1750 words

International relations - Essay Example Further, the customs and the heterogeneity of the indigenous populations within each national territory as defined by the physical boundaries have concentrated on minding the issues of their own territories, as opposed to focusing on integration of the region. Thus, despite the region having a higher potential for contributing and even influencing the global geopolitical and economic system, the disconnected territories have retained their cultural, political and economic developments within their individual territories (Severino, 2009). Nevertheless, it cannot be argued that the region lacks inter-countries interaction completely. There has existed some interaction among the different areas of the South East Asia, although the interaction has been such minimal as to significantly alter the preservation of the individual cultures of these nations. Consequently, the idea of the formation of the Association of Southeast Asian Nations (ASEAN) was one major stride towards bringing this r egion into a common economic bloc, which would then be able to negotiate its political and economic space in the global geopolitical and economic system (Lee, 2006). There is no doubt that the region could be highly influential on the global platform if it could be united under one umbrella, which would act as its vehicle of international negotiations. However, the preservation of strong individual culture among the nations of the South East Asia region has played a major role in hindering the formation of the regional economic bloc. The competing interests purely based on the uniqueness of the individual culture of each nation has meant that creating a regional bloc that would integrate the South East Asian countries of Philippines, Thailand, Indonesia, Malaysia and Singapore (Basu, 2013). The ASEAN was first established on 8 August 1967, when the five countries came together and signed the Bangkok declaration, which founded ASEAN as a loose organization (Lee,

Computing, Society and Ethics Research Paper Example | Topics and Well Written Essays - 1000 words

Computing, Society and Ethics - Research Paper Example This prevents the distortion of the correct information thus avoiding unnecessary errors during treatment which is administered by the doctor. In addition, the new hybrid robot-assisted procedure reduces the painful operation process and also reduces the time spent on one patient. Advancements in technology result to increased effects of computers to the society, thus ethics should address evolving issues surrounding the use of the remote heart surgery (Duquenoy, Penny, Simon, and Barry 78). In the health sector, the remote controlled robot plays a key role in the entire process of heart disease diagnosis and treatment. It is a vital process in that it directly affects the life of other people thus the standards of its ethics should be high. The remote heart surgery equipment has two parts; the control console and the operating component which is the actual robot. Ethics related to the robot are used in decision making, which is necessary in saving the lives of patients. Written codes relating to cardiac procedures that are robot-assisted guide the doctors in the administration of proper treatment. In their research and implementation of new surgical equipment in the health sector, doctors should abide to the set ethics. Importantly, the remote heart surgery plays a substantial role in these discoveries; thus there should be a close working relationship between the two ethics. The lives of patients suffering from heart disorders depend on the accuracy of the robot arm t hat medics implement for treatment. Often, the robot is directly related to computers as it uses computing commands in its functioning process. This means that computing ethics have a direct effect to the society and influence enormous activities in the surgery procedure (Rosenberg 99). The remote heart surgery is an example of the intensity of computing in treating heart

American Institute of Certified Public Accounts Code of Professional Conduct Essay Example for Free

American Institute of Certified Public Accounts Code of Professional Conduct Essay The American Institute of Certified Public Accounts (AICPA) Code of Professional Conduct is a body of principals that has a goal to guide Certified Public Accountants (CPA’s) in the â€Å"performance of it professional responsibilities† (Mintz, 2011). The AICPA Code of Professional Conduct has six essential principles and they are: Responsibilities, the Public Interest, Integrity, Objectivity and Independence, Due Care, and Scope and Nature of Services. Each of these principles is meant to be followed by the members of the AICPA. These articles are used to explain the responsibilities that CPA’s have to clients, colleagues and to the public. The first principle, Responsibilities, protects the public of irresponsible and immoral behavior. The Public Interest makes sure the public’s best interest is protected. The third and fourth principles guarantee that the trust of the public is greatest served; integrity, honesty and confidentiality are of highest importance, as well as objectivity and impartiality. The fifth principle deals with the level of quality service and competence that the public receives and deserves. The sixth principle ensures that CPA’s have good internal controls put into place, and makes sure that CPA’s are unbiased and free of conflict when performing an audit for a client. These principles are put into place to protect the public and also to protect CPA’s, because as they follow them they will ensure that their practice is honest, responsible, and ethical, allowing no leeway for unethical behavior. The most important purposes of the AICPA Code of Professional Conduct are to honor the public’s trust, to enforce the ethical obligations of the CPA’s and to provide guidance in the performance of the professional responsibilities. Although it appears seemingly simple, honoring the public’s trust is not always a first priority for many within an organization. The AICPA principles places the public’s trust first, as one must for all CPA’s, and makes it important that CPA’s act in the best interest of the public, even if it does not serve in best interest of the CPA. By behaving ethically, CPA’s show respect for the public and its interest, and they are able to carry out their duties and commitments to the public. Finally, CPA’s have the obligation to perform their responsibilities to the public to the best of their ability, putting always first the best interest of the public.

Condoleezza Rice Essay -- Politics Political

Condoleezza Rice   Ã‚  Ã‚  Ã‚  Ã‚  At this point in time the name and image of Condoleezza Rice is commonplace among the majority of informed Americans. As the first female to serve as the National Security Advisor to the President of the United States, Dr. Rice was propelled even further into the spotlight following the attacks on America on September 11th 2001. I too, like most Americans, saw a lot more of Condi, as she is known by her many friends and colleagues, after September 11. Clearly she was intelligent and always remained calm and poised in the face of adversity and standing before the cameras. I also noticed and appreciated her articulation and was even moved by what seemed like her stoic yet compassionate presentation. It was not until I read Dr. Rice’s biography, Condi, by Antonia Felix, however that she gained my utmost respect. By the 21st century a black successful black female is not as uncommon as it was fifty years ago. Black women had fought their way to the top in many arenas, including political such as the U.S. Senate. What is truly amazing about Condi’s story is speed and finesse with which she ascended to the top of everything she took on. An endearing friendship and mutual loyalty with both of the George Bushes surely did not hurt her. Condi’s  Ã‚  Ã‚  Ã‚  Ã‚   success was hardly limited to the world of politics. She approached music, fitness, academics, sports, religion, and family with the same decisiveness, consistency, and determination that she brought to the public sector. Condi is also no stranger to controversy. Now more than ever she faces a host of critics, especially regarding her supposed knowledge of possible terrorist threats before they came to pass on September 11. Her Republican politics made her less than popular among African Americans although she maintains a more liberal perspective on social issues and remains pro-choice. In spite of her ups and downs it is ultimately her unfaltering character to which sh e can attribute her success as well as her status as what many call the most powerful woman in politics.   Ã‚  Ã‚  Ã‚  Ã‚  The high academic pursuits of the Rice family did not exactly begin with Condoleezza and her generation. The foundation of this idea can be seen in chapter 2 of her autobiography in which the author begins the chronological record with a look at Julia Head Rice. Julia was born into slavery, albeit house slavery which was h... ...onsibilities were never ending and she approached them with the same grace and drive as she does everything in her life. Although the book end its documentation in 2002, shortly after 9/11, Condi’s duties have become no less urgent. Since that time she has had to defend her Administration against suggestions that the attacks could have been prevented and has done so quite well. The 2004 elections have just been completed and George W. Bush is returning to the White House for another term. Former Secretary of State Colin Powell has submitted his resignation and Condoleezza Rice has been nominated as a predictable replacement. If she survives the Senate approval hearings she will become the first black female and second female to fill the role. While I have full faith in her abilities I am concerned with the fact that without Powell in the National Security Council there will be no dissenting opinions. The proposed administration is politically homogenous. Surely Dr. Rice wo uld understand this concern as she herself is quoted in the opening lines of chapter 8 of her biography as saying â€Å"If you find yourself in the company of people who agree with you, you’re in the wrong company.†

Music: the Medicine of the Mind

Music can have effects on the human brain that are hard to exaggerate. For instance, a mere snippet of song can trigger one’s memories so vividly. A tune can induce emotions ranging from unabashed joy to deep sorrow and can drive listeners into states of patriotic fervour or religious frenzy–to say nothing of its legendary ability to soothe the savage beast. The study of how music affects the mind and the interconnection between music and the physical and mental health of human beings has been a subject of interest for many.Music is known to speed the recovery of health ailments and has a calming effect on the mind. Music helps fight anxiety and has a soothing effect on the brain. Music may affect the brain/mind by increasing creativity and problem solving skills; concentration and memory; and speeding up healing. Music increases creativity and problem-solving skills. Music enhances creativity, by positively impacting the right side of the brain where most of oneâ€℠¢s creative thought is situated and triggering brain centres which deal with enhancing creativity.For example, according to the article â€Å"Healing by Music Therapy – Ragas† From the online magazine: ‘Akhand Jyoti’, certain ragas (A pattern of notes in Indian music that have characteristic intervals, rhythms, and embellishments, used as a basis for improvisation) activate the chakras of the body, thus giving the individual an added advantage in other creative tasks. Additionally, music increases spatial and abstract reasoning skills required in tackling problems, solving puzzles and decision-making.Moreover, according to Eric H. Chudler, Ph. D. , a lecturer at the Washington University Faculty of Music, â€Å"the brain responds to the â€Å"Mozart Effect†; listening to classical music for a period of 10 minutes appears to increase your creative abilities. † Therefore, listening to Mozart's music positively affects the spatial-temporal reaso ning, simply put; it ‘makes one smarter’. Furthermore, music increases concentration levels and improves memory.According to the online article â€Å"The Brain on Music† by the neurologist Dr. Ellen Weber; â€Å"Classical music, such as Haydn and Mozart, often improves concentration and memory when played in the background. † Hence, music helps increase your concentration levels a great deal. In addition, music has a calming effect on the mind, so, the calmer the mind, the easier it is to focus and concentrate. Additionally, music has been found to increase memory levels of Alzheimer's and dementia patients.The silence between two musical notes triggers brain cells which are responsible for the development of sharp memory. Flute music, and instruments like the santoor and sarod are recommended for the enhancement of concentration and memory. Also, classical music improves the ability to recall what's retained in the brain in the form of memory. Strong beat s cause the brain waves to resonate in synch with the beat, thus, leading to increased levels of concentration and increased mental alertness. Moreover, music acts as a catalyst in the healing process.According to the online article â€Å"Music and the Healing Process† from the Thorburn Associates Acoustic and Technology Consultants website, â€Å"There is also significant research that music can be used in medicine to help manage pain, reduce anxiety†¦Ã¢â‚¬  Hence, music is an effective distraction from pain and suffering of the sick and injured, however, music not only diverts the mind from pain, but also helps bring about certain chemical changes in the brain, such as, enabling one’s mind to secrete endorphins that speed up the process of healing.As a result, music therapy is recommended for patients of high blood pressure, heart diseases and even cancer, so, music may be considered as therapeutic in pain management. Therefore, listening to melodious, comfort ing music is sure to have a positive effect on the physical and mental well-being of patients. If not cure every ailment, music definitely creates hope in the minds of patients – a hope to recover. And when nothing else works, only hope does. To sum up, increased creativity and problem solving skills; concentration and memory levels; and speedy healing, are the effects music has on the mind/brain.Music really affects the human mind a great deal. So much so, that it influences one’s physical and mental state. Music aids in the speedy recovery of ailments by diverting the mind away from the pain as well as through chemical changes in the brain brought about by music which catalyse the healing process. In addition music calms the mind, helps fight anxiety and has a soothing effect on the brain, thus, increasing one’s concentration and memory levels. Lastly, through triggering brain centres and stimulation of the right side of the brain, music enhances an individual ’s creativity and problem-solving skills.

Narrative style of the novel Essay

Comment on how the language contributes to the understanding of the character, plots, theme and narrative style of the novel Chapter 6 is presented to the audience entirely in the past with no hindsight. Once again it develops the plot showing the children developing closer to adulthood, yet still not quite there, not understanding the consequences of their actions : â€Å"was it you two? â€Å", â€Å"I look away†. The language from the passage in the hard back page 111 to 113 contributes to the understanding of the characters, plots, themes and narrative style of the novel. The section about the hierarchy in trees only further reinforces the naivety and stupidity to the character Stephen. Stephen has an obvious sense of hierarchy and in this case the â€Å"sour smell of the elders† and â€Å"its humiliating position at the very bottom of the hierarchy of trees†. This continues into the â€Å"familiar world† â€Å"out here at the end of the Lanes†, ie: the hierarchy of humans where the levels convey Stephen’s actual opinion of the concept of hierarchy and social status. This shows how immature Stephen is and however evident is his naivety. See more: what is a narrative essay In hindsight Frayn exposes the audience to the intentional irony of the â€Å"sliver framed heroes† at the highest to the lowest – â€Å"an old derelict taking refuge† who are the same person. Frayn has emphasised this hierarchy from the beginning. Stephen feels in triumph that for once he perceives himself higher than someone else in the â€Å"human precedence† and the language emphatically robusts this. This only reinforces that younger is obsessed with hierarchy – only after the discussion of hierarchy is there a sense of realisation. The language in this passage contributes the understanding in the theme of mystery and adventure. Stephen relies on this adventure to prove himself to Keith and in doing so show â€Å"Keith that he’s not the only one who can think of plans and projects†. The use of personal pronoun ‘I’ used more frequently than other times (7) conveys Stephen’s awareness that at this point in the adventure, wherein he can contribute, is a way he can gain approval of others even at the exploitation of the tramp. The passage for the first time shows an all time low in the adventure and â€Å"rain blows† as deliberate violence. This marks a key turning point in the plot as they have to fine some reason for their expedition as they have lost Mrs Hayward. The language used to describe the â€Å"old mans† feelings are just some of the feelings evoked that explain exactly what the boys have been doing bullying, and in doing so, the language also introduces the theme of memory. Frayn draws attention to this key theme by making older Stephen interrupt his story to remind the audience that the Stephen who was once a victim of bullying is now the perpetrator. This narrative style is a device that suggests implausibly that older Stephen is telling the story and also draws attention to memory as a concept and theme. Not only that, but it helps the reader understand that the reason â€Å"I (Stephen) throw down my iron bar†, is to reflect what Stephen knew at that point in time is that what he was doing was bullying. In this passage Frayns presents the language as a way of children going on to do adult things but without adult hindsight and therefore reminds the audience that they are still developing unable to foresee the consequences of their actions. The language is deceptively simple in style, but the passage in Chapter 6 shows a subtlety in language. From the beginning of the passage Stephen shows this middle class social ranking which leads him into his so called heroism that is particularly associated with middle class values. This duty he is estranged with towards Keith was particularly powerful conception in times of war and for Stephen it shows a development in his character and what he is prepared to do out of duty for Keith. Thus, Frayn cleverly uses linguistic devices and in this case exploits the language in order to contribute to the understanding of the characters, plot, themes and narrative style of the novel.

The Impact of the Eighteenth Century Books essays

The Impact of the Eighteenth Century Books essays Since the nineteenth century, the world had been changing really fast. As we have made dramatic progress in the science technology, the quality of life has been changed rapidly. However, those improvements of our lives have made us lazy to do anything because today our lives are flooded with the articles or goods. It is said since then that now we live in the hedonistic and materialistic culture. Living in those cultures, people do not need to care or worry about anything, and I think people dismiss from their minds to live together in peace because people tend to place a special emphasis more on the articles than on other people. As we start living in the hedonistic and materialistic culture, we have lost the value of the moral sense. Even now, it is worth to read and study a eighteenth century book, like Autobiography of Benjamin Franklin, because it reminds us of the moral standards dismissed from todays our lives. I think many people who make a success of life today are influences by the eighteenth century books. Recently I have read the books about empirical and successful philosophy, such as Andrew Carnegie and Napoleon Hill. What they said in a book is really similar to what the eighteenth century books said. Both book claim that the moral standard is necessary to make a success of life or to obtain happiness in the course of life. Although many people want to make a success of life or obtain happiness, they tend not to practice the moral standards of old fashioned values. In the hedonistic and materialistic culture, our societies have been brimming over with insincere attitude, falsehood, hatred, envy, and jealousy. This is a reason why the moral sense of old fashioned values has been lost in our societies. However, anybody can change oneself or ones mind; I think the eighteen century books were written about the moral sense because of the Enlightenment. Especially, the Autobiography of Benjamin Franklin has inf...

Calcium Absorption Essay In order to determine the content of calcium and magnesium in an unknown sample of limestone, the utilization of atomic absorption spectrophotometry can help in deciphering the unknown concentrations of each molecule in the limestone sample. Atomic absorption spectrophotometry, emits radiation of the correct frequency that is passed through a flame and the intensity of the transmitted radiation is measured?. The calcium concentration or ppm can be measured using the absorbance of the solution and comparing it to a standard curve for calcium?. Whereas magnesium, needs to be determined using the standard addition method. The concentrations of each respective molecule can be presented as CaO and MgO percentages of the unknown limestone sample. Materials and Methods The compound calcium carbonate (CaCO3, CAS: 471-34-1, 204. 89ppm) was utilized to compare its absorbance to the unknown sample of limestone # 8066 on the standard curve. Moreover, magnesium sulfate heptahydrate (MgSO4*7H2O, CAS: 10034-99-8, 40. 8ppm) was also utilized to compare its absorbance against that of the unknown. Lab personnel from the CSU Eastbay department of chemistry stockroom performed all calibrations on the Perkin Elmer AAnalyst 300 atomic absorption spectrometer. All chemicals used in this experiment were obtained from the CSU Eastbay department of chemistry stockroom. A Denver Instrument Co. Sargent-Welch analytical balance was used to determine the mass of the unknown, mass of calcium carbonate, and mass of magnesium sulfate heptahydrate. A Perkin Elmer AAnalyst 300 atomic absorption spectrometer equipped with a Lumina Calcium and Magnesium Lamp was used to determine the absorbance. The instrument used Argon and Acetylene as the carrier gas and oxidant gas, respectively. Calcium Absorption. (2018, Oct 17).

Validity, reliability and generalisation in the research process Essay

Validity, reliability and generalisation in the research process - Essay Example In addition, the essay provides recommendations, which include a series of questions that could be incorporated into a questionnaire aimed at finding out why post graduate students choose to study HRM. In management research, validity, reliability and generalisation should be addressed in research with a lot of caution because it is tricky to distinguish them precisely. For instance, validity is defined as the relationship between test results on research with other objectives that the study seeks to achieve or measure (Wainer & Braun, 2013: 40). Therefore, researchers should clearly outline their research objectives. On the other hand, Schensul, LeCompte and Schensul (1999: 271) define reliability as the consistency of research results and the ability of such results to be replicated by other researchers. It is worthy to note that a measure may be reliable, but such a measure’s reliability does not ensure its validity (Rubin & Babbie, 2010: 87). It is imperative that business and management researchers should consider reliability and validity separately. This is because reliability is about consistency while validity is about truthfulness in measures (Jackson, 2013: 90). On the other hand, seeking to ensure reliability in management may distort the purpose of a study. This is because a researcher will design a measurement tool or process that will ensure the results obtained from such a study will be replicated by other researchers. This leads to a researcher’s slight deviation from the original purpose of the study, which may in turn, adversely affect validity. Separately, generalisation may be used in businesses and management research to contribute to theory. Therefore, in consideration of generalisation, management research should be designed so that it is properly conversant with theory to contribute to
