Agriculture and the Nitrogen Cycle Essay Example for Free

Agriculture and the Nitrogen Cycle Essay Agriculture is an important industry that provides food for human consumption. The decrease of land available for agriculture coupled with the increase of human population has required that agricultural lands increase their output. This was achieved through the use of improved crop varieties, more productive livestock, better weed and pest control and the increased use of fertilizers, specifically nitrogen fertilizers which has linearly increased to 1. 2 Mt in the 1980s. However, farming also affects the environment. Increases in phosphorus and nitrate contents of water lead to increased biological activity and large concentrations of nitrate in drinking water create health hazards. J. K. R. Gasser studied the nitrogen cycles in agriculture and reported the results in his article â€Å"Agricultural Productivity and the Nitrogen Cycle. † Gasser (1982) explained that nitrogen is emitted from the soil or from animal effluents as ammonia, nitrous oxide or N2. Considerable amounts of nitrogen are also recycled directly as animal urine and feces. The preceding crops in agricultural lands also affect the amount of nitrogen released for the current crops. However, Gasser (1982) explained that no arable system provides enough nitrogen for the maximum production of crops such that additional nitrogen must be added in the form of fertilizers. Gasser (1982) reported that there is no evidence supporting that the increased use of nitrogen fertilizer also increases the total amount of nitrogen in soil-plant system. He stated that little of the nitrogen in circulation â€Å"will appear directly in the atmosphere or groundwaters, most will leave the agricultural system after one or more changes or subsidiary cycles† (Gasser, 1982, 313). Gasser (1982) concluded that the losses from the system must be at least as large as the known inputs. He persuaded to quantify the movement of nitrogen, the understanding of which would allow the losses from agricultural system to be minimized improving the utilization of nitrogen in farming and reducing its effects on the atmosphere and water.

Dostoevsky as Performer Essay -- Russian Literature Christianity Relig

Dostoevsky as Performer Storytelling and reading aloud played a valuable part in young Fyodor's life, influencing his own later successful writing endeavors as well as his performance of literature. His nanny and wet nurse introduced the Dostoevsky children to folklore and lives of the saints through the stories they told. Nanny Alyona Frolovna "told the children stories of ancient Russia, of Saint Sergey of Moscow subduing a bear by the power of his holiness, of heroes and legends and folk tales, Christianity and Russian myth intertwined"; the stories were so vivid and frightening that the children had trouble sleeping (Gunn 10). During the winter their former wet nurses would make a ceremonial visit to the Dostoevsky family, staying two or three days and spending the afternoons telling stories. Such is the power of the spoken word that these women, according to Leonid Grossman, "awakened the boy's interest in the oral poetry of his people and at the same time fostered the development of that beautiful lan guage--freeflowing, emotionally charged, profoundly Russian and memorably expressive--in which, in time, his worldfamous books would be written" (10). Joseph Frank attributes these storytellers' tales of the saints with feeding "Dostoevsky's unshakable conviction that the soul of the Russian peasant was imbued with the Christian ethos of love and selfsacrifice" (1976, 49). The Dostoevsky children were also entertained and educated with oral readings by their parents, especially during the long evenings of the Russian winter. As the family gathered in the parlor, the physician father would read aloud before dinner when he was not occupied with his patients, and the children often went to sleep with the sound of one of th... ...Indianapolis and New York: BobbsMerrill, 1975.

Grilled cheese math assignment Essay

In our problem for the week of special topics were are given a problem regarding achieving a best time to make grilled cheeses in a efficient manner in the shortest amount of time. The problem states; You need to make five grilled cheese sandwiches. You have a grill that is large enough to toast two sandwiches at a time. The sandwiches must be toasted one minute on each side. It takes 3 seconds to flip a sandwich and 5 seconds to take one off or put one on the grill. What is the shortest time needed to toast all five sandwiches? So with the information given we can conclude that the sandwiches have to be toasted at least 5 mins so it is obvious we cant get anything lower then 5 mins. Next we make an assumption that we can flip two sandwiches at the same time as well as take off and put on two sandwiches as well as take off two sandwiches all simultaneously. So the best way to solve this problem would be to first simpify the problem so that it is easier to see the soultion. So I decid ed to label the grill cheeses. Each side is denoted by A, B,C, D, E. So assuming the time starts for for the countdown when the two sandwiches are put on the Grill. Step 1: A B toasted one side 1 min =1min Step 2: Now Remove B and put C 5sec+5sec+3sec=13 sec( for removing B 5 sec + put C 5 sec+ flip A 3sec) Step 3 A C toasted on grill 1 min =1min Step 4: Now Remove A(completed) and put D 5sec+5sec+3sec=13 sec ( for removing A 5 sec + put C 5 sec+ flip C 3sec) Step 5 C D toasted on grill 1min =1min Step 6 (remove C(completed) ,put E, flip D) 5sec+5sec+3sec=13 sec Step 7 D E toasted on grill toasted 1 min =1min Step 8 remove D(completed), put B , flip E 5sec+5sec+3sec=13 sec Step 9 B E toasted on Grill 1 min =1min TOTAL = 5 min. 52 sec The process stops as all the five sandwiches are toasted, time is not counted for not taking the A and E off the grill. So the shortest time achievable needed for grilling all the five sandwiches as well as taking them off is 5 minutes and 52 seconds.

The Voice of a Feminist Rhetorical Analysis Essay

The Voice of a Feminist: Rhetorical Analysis of â€Å"Claiming an Education† â€Å"All I have, is a voice.† –W.H. Auden. These are five words that could leave a thoughtful philosopher speechless. But perhaps found within the lack of â€Å"finding a better word† moments, are when revolution seeds are planted in the hearts and tongues of the passionate. And if this is a truth, then Adrienne Rich was absolutely no exception. The radical feminist and poet opened her speech, â€Å"Claiming an Education† to the girls of Douglass College, in the most straightforward way as possible. In skimming the text, only the reader can imagine what was really communicated in the zeal and urgency behind her rehearsed words that day in 1977.

In the brief age of revolution, the nation also began to see the importance of women studies in high education institutions (Elfman, â€Å"A ‘Second Wave of Feminism’†). In the text, Rich divulges in her views on civil rights, emphasizing on her bias view on women suffrage in education, but rationalizes it with social currency: â€Å"...You, the women students here, and†¦ us, who teach in a women’s college [are two parts of education]. But ultimately those two parts are indivisible†¦ Less than a decade ago, with the rebirth of a feminist movement in this country, women students and teachers in a number of universities began to demand and set up women’s studies courses – to claim a women-directed education (Rich, 220, 221).† Whether it was intentional or not, Rich’s use of the word â€Å"indivisible† when describing the bond of female student and teachers (with no gender specific aim), was utterly relevant to say the least.
