The Desert Makers essays

The Desert Makers essays By the process of desertification, the Sahara desert is growing at a rate of 0.6 km a year. 'Millions of people in this area are suffering from the effects of this phenomenon, which causes the earth's ecosystems to deteriorate" . Sand dunes have covered large expanses of agricultural farmlands, oasis and ponds, causing farmers to abandon the season and their homes. Desertification is posing a serious threat to Nigeria's economy as jobs are lost, and food is becoming scarce. The deteriorating economy is at the fault of the Nigerians, the negative effects of desertification could have been, and still can be slowed down and even prevented by the Nigerian government and its people. Although desertification is a natural process of an ecosystem, it could have been stopped. The people of Nigeria and even many surrounding countries have taken up many processes that are increasing the rate of desertification. Nigerians are poor and live by the easiest ways of life, which is very destructive towards the environment. Instead of looking for long-term processes to help take them out of their poverty, Nigerians over cultivate and overgraze the land they live on. They destroying it and then moving on to ruin a fresh new area, in turn leaving a path of infertile soil to be never used again and ready to be swept away by wind erosion and turned into the dry desert ecosystem. "Grasslands that once provided good grazing and nourished sturdy crops are turning to barren wastes." Overgrazing is one of the biggest problems of the Nigerians. "For centuries people have raised livestock in the lands bordering the deserts. Mixed herds were driven from one grazing area to the next." Hundreds of animals were herded and soon Nigerians needed to wander far to find food for the flocks. "Their hoofs pound the dry earth hard so that new shoots can not break through, and cripple trees" . Nigerians traveled with their flocks, and land was being destroyed as they m...

Sonnet CXVI essays

Sonnet CXVI essays By looking closely at the sonnet, consider to what extent its particular techniques add to the impact of its subject matter. The sonnet Let me not to the marriage of true minds written by Shakespeare is about constant love. There are three quatrains that are about the three stages in true love and a final couplet. The poem is a sonnet because it has fourteen lines in iambic pentameter. In the fourteen lines of the sonnet there are three quatrains and a final couplet. This is the structure of all sonnets. The rhyming scheme was fixed with the pattern of abab cdcd efef gg. The three quatrains were all on the subject of love and how it is kept constant. In the first quatrain Shakespeare uses alliteration with the letter m. He wrote Let me not to the marriage of true minds admit impediments. The m sound is smooth, and makes the beginning of the quatrain be in a relaxed mood and in harmony, so it is like the start of a relationship. Also in this quatrain repetition is used with love, remove and alter. These also make the poem sound smooth and also secure because words are used twice. Using repetition also reinforces the idea of constancy, which is like the love in this sonnet. In quatrain two the main technique is metaphors, using sea imagery. Shakespeare says love is an ever-fixed mark that looks on tempests and is never shaken. He is comparing love to a lighthouse, as however stormy the sea is for ships, the lighthouse will always be there to guide them, and even though in a relationship there may be arguments, there will still be love. With a similar idea Shakespeare says, It [love] is the star to every wandering bark. He is saying that a star guides a lost ship in the right direction, this is like love, which guides people and shows them the direction they need. Throughout the third quatrain there is an e ...

Ode to the West Wind Essay Example

Ode to the West Wind Essay Example Ode to the West Wind Paper Ode to the West Wind Paper Shelley’s â€Å"Ode to the West Wind† The eighteenth century was a time of revolution in Europe; the French Revolution. It introduced a new era of enlightenment and individual freedom. This revolution led the poets to explore freedom, independent ideas and limitless imaginations on poems. This movement was called Romanticism and it was characterized by stressing new ideas of nature and change. Percy Bysshe Shelley took up these revolutionary ideas in his poems. In â€Å"Ode to the West Wind†, Shelley presented the idea of old new which reminds the image of revolution. In the first three lines, he casts a deceased atmosphere by mentioning the dead leaves are like the ghost. And then, Shelley use the phrase winged seeds in line 7 which presents images of flying and freedom. â€Å"The winged seeds, where they lie cold and low,/Each like a corpse within its grave until/ Thine azure sister of the Spring shall blow. †(791) He says the winged seeds are lying cold and low right now but soon azure sister of the Spring shall blow. He shows the reader a feeling of being trapped and then says new life will come out of a grave. The word choice â€Å"Spring† here signifies his intention of theme â€Å"new†. The phrase winged seeds also brings image of an angel and its heavenly images are confirmed by his use of the word azure. He somewhat implies death as old and winged seed as new opportunity and new life. Another of the central ideas of him exemplifying the revolutionary ideal is the usage of words of nature. During the Romantic, nature began to be used as a way to express emotions. It wouldn’t be taking long for the reader to find the words that relate to nature. Leaves(2),earth(10),flowers(35),woods(39),forest(57) these are words that provokes the reader to think of the image of nature. The last of the central ideas of him exemplifying the revolutionary ideal is the theme of change. Shelley desires a social change and the West Wind is working as symbol of change. The last two stanzas are Shelley speaking directly to the wind, asking for its power. He seems to ask the wind to take his thoughts and spread them all over the world so that his next generations, the youth, seeds are awoken with his ideas.

Friction Lab Report Example | Topics and Well Written Essays - 750 words

Friction - Lab Report Example Static friction is the friction that tries to hold the object in position. A book positioned on a table has a static friction. The coefficient of static friction is denoted by  µ. Dynamic friction is associated with the surfaces that in constant motion with each other. The friction force between the engine rotating parts is dynamic friction. The major aim of the experiment is estimate the coefficient of static friction. It can be evaluated by pulling a box with known weight along a surface with smooth flat symmetry. The coefficient of static friction and normal force (FN) are correlated to each other when one surface starts to slide over the surface. FF is the frictional force that is in opposite direction to the tension force. Force of gravity tries to pull the box down and normal pull force (FN) in opposite direction to the gravitational pull force. In this experiment we have to estimate the relationship between FN, FF and  µ (coefficient of friction). Friction of the object is directly proportional to the weight of the object; as the weight increase, the force of friction also increases. During the experiment, the box with more weight required more force to be pulled from its position. It means that the weight of the object increases its frictional value. On the other hand, comparatively less force is required pull the small box. This estimate can either be wrong as heavier weights require more force in general. Coefficient of friction also increases as the weight increases. We have estimated the ratio of FF and FN and found that as the weight of an object increases, the coefficient of friction also increases. The other observation is that the surface area of the object in contact with the other surface also influences frictional force on the object. In our experiment, the box with more weight has more surface area in contact with the surface below and thus produced more friction. On the other hand, the object

Stem Cell Essay Example | Topics and Well Written Essays - 500 words

Stem Cell - Essay Example For millions of others, the time has come to overcome the unfounded religious and political obstacles that have log-jammed this river of hope and proceed with stem cell research and development. The application of stem cell research is an ethical endeavor that could result in the saving of millions of lives, untold misery, and offer hope to millions that suffer from disease and disability. Stem cell research is science. It is no less science than in-vitro fertilization, organ transplants, and blood transfusions. Our scientific tradition compels us to explore new uses for science and craft ways to put it to work to alleviate suffering and premature death. Blocking science for political purposes is unconscionable and as Kinsley reminds us, "Imagine being paralyzed by a spinal cord injury in your teens, watching for decades as medical treatment progresses but not quite fast enough, and knowing that it could have been faster." This concern is also shared by an overwhelming number of Americans. While most Americans favor moving ahead with stem cell research, those that oppose it most often cite religious objections as their reason (Americans Speak Out). Strict conservative Christians have blocked federal funding for increased research as they have mistakenly related it to the abortion issue.

Investment Portfolio Implementation & Management Essay

Investment Portfolio Implementation & Management - Essay Example The following aspects have been considered before formulating the appropriate asset allocation strategy for the investor: An investment portfolio consists of a number of asset classes which have different levels of standard deviations, returns and yields. The assets that are to be included within an asset allocation model depend largely on the kind of return being expected by the investor and the risk that the individual is willing to bear (Market Watch, 2013). Therefore before preparing the asset allocation model, the first thing that needs to be identified over here is the latest investment benchmark figures of the different asset classes. Considering the above mentioned investment benchmarks, 8% of Dr. O’Hara’s investment should be made behind intermediate bonds as the investor wants to invest $30,000 in an asset that is considered safe and is associated with no expense, sales or early withdrawal charges. This will enable Dr. O’Hara that a guaranteed return is realized at the end of maturity thereby enabling the individual to pay for travel expenses without any inconvenience. Now, considering the fact that Dr. O’Hara wants to earmark $60,000 in an account with higher than current certificate of deposit or money market rates but minimal market volatility, 17% of the total investment sum should be invested in short term bonds. They have a standard deviation value of 0.68% indicates that this asset is less volatile. Therefore, keeping $60,000 earmarked for an investment in short term bonds will enable the investor to enjoy a return close to 0.71%, 1.23% and 2.74% respectively in bonds with 1 year, 5 years and 10 years maturity. The remaining 75% of the investment fund should be distributed appropriately between large cap stocks, small cap stocks, mid cap stocks and international stocks. 27% of the investment fund should be invested
