Oldham Pond - Essay Example An example of a response by the ecosystem would be a spurt in the population of phytoplankton in the aquatic body, due to an upsurge in the nutrient level (John & Eugene 109). This phenomenon has such negative effects on the environment as hypoxia, which is oxygen depletion in the water. On top of promoting an increase in phytoplankton levels, it also promotes plant decay, while seeming to favor natural plankton and algae as compared to more developed plants. This plant decay causes a substantial reduction in the quality of the water, as well as depletion of aquatic oxygen during decomposition of algae, which causes death of fish. Eutrophication decreases the recreational value of water bodies, hurting tourism. The premise of this paper is to study Oldham pond and its tributaries and evaluate the effects of eutrophication. Conductivity of the pond was measured using a portable conductivity metre. Conductivity is the measurement of how much material found dissolved in the pond. Polluted ponds have more dissolved solute than clean ponds. Conductivity below 250 is preferable, with upward of 600 being the cause for alarm. Measurement of temperature was done using a thermometer, while the levels of dissolved oxygen were measured using a dissolve oxygen electrode (Ansari 90). The sampling was carried out on the 4th and 25th of February, 2012. For the organisms in the pond, Ad Libitum sampling was used, where much information about the organisms was measured (John & Eugene 106). According to the results, the temperature of the water was comparable to that of the surrounding air. The slight difference is the difference in conductivity of heat by air and water. Dissolved oxygen levels were also concurrent to those that are recommendable (11 mg/l). Conductivity, however, was found to be higher than recommended. Recommended conductivity is below 250 (Boqiang et al

A Critique of Sir Anthony Hopkins's Oscar winning performance of Hannibal Lecter in 'The Silence of The Lambs' - Essay Example 3 Hannibal was by all accounts an evil, savage, cannibal and serial killer and yet he became an enthralling, and often sympathetic character.4 The fact that a psychiatrist who murders and then eats his patients could become such a captivating character is puzzling.When Hopkins meets the FBI agent for the first time,I could not help thinking that he while he seemed to be toying with her,he had some degree of respect and suspicion in his interaction with her and Hopkins gave these impressions through body language and inflection.At one point he winked at her as if to share a private joke and at another point,he smiled at her,giving the impression that he had normal feelings.In my opinion, Hopkins brought a very complex character to life in a realistic and convincing way.Lecter was â€Å"psychopathic personality evidenced by his superficial charm,manipulativeness and lack of remorse of empathy for the victims†.For example, when the agent interviewing Lecter mentioned that serial killers usually kept a relic of their victims, Lecter interjected, â€Å"I didn’t† in a matter of fact way. ... After all, Lecter was previously portrayed by actor Brian Cross and introduced him to the screen, it was Hopkins’ Lecter that made the greatest impression and immortalized him.7 Hannibal Lecter was a brutal cannibal and there was nothing sympathetic about the character and it was not intended that Lecter was sympathetic. Lecter is â€Å"revoltingly evil, a characterization brought chillingly to life for millions by Anthony Hopkins† in Silence of the Lamb.8 For example when discussing the murder of a former patient, Lecter denies killing his patient but states without emotion that it was best for him â€Å"as his therapy was going nowhere anyway†. However, Barr explains that Hopkins was brilliant in how he chose to play Lecter.9 Hopkins portrayed an ordinary man who did extraordinary deeds and came across as a man you would not run away from if you happened to come across him on the streets. I observed this in his demeanour as he urged the FBI agent in training to show her credentials and when she did, he urged her to come closer, as if he did not think she should fear a man like him. In other words, Hopkins played Lecter as though, Lecter thought of himself as normal and this brought both sympathy to the character and made him likable and evil all at the same time. One acting technique that Hopkins brought to the character of Lecter was his refusal to judge the character. As Hopkins himself said: †¦As an actor, I can’t judge because moral judgement gets in the way of the characterization. If you start doing that, you end up playing the character like a zombie or a vauderville villain.10 In other words, Hopkins took and inside-out approach to his portrayal of Lecter. He portrayed the character by
