Introduction Eutrophication is a condition in an aquatic ecosystem where high nutrient concentrations stimulate blooms of algae (e.g., phytoplankton). Eutrophication is a natural process that occurs to all lakes over time as the weathering of rocks and soils from the surrounding area that leads to an accumulation of nutrients in the water. It can also be caused by run-offs of fertilisers. Three of the key components of modern fertilisers are nitrogen, phosphorous and potassium. After a rainy…

In his 1987 book, The Closing of the American Mind, Allan Bloom makes the case for what he describes as higher education failing democracy through an emphasis on historicism and relativism. This academic emphasis, for Bloom, creates a paradoxical restrictive freedom in the minds and hearts of students, leaving them without a moral compass, and creating a void that can easily be filled with demagoguery. Along the way, Bloom staunchly defends elitism and ethnocentrism, attacks feminism, and lays…

Background/ Introduction An algal bloom is an increase and accumulation of algae in freshwater or salt water systems. Most algae blooms are caused by blue-green algae. Blue-green algae is actually not algae at all, it is a cyanobacteria. A bloom can lead to a green, blue-greenish or reddish discoloration of the water, and if the algae bloom lasts long enough streaks or scums may appear on the water surface. (UBA. 2016) One harmful element of algae blooms is that they…

often leads to toxic algal blooms. These algal blooms are quickly fueled by the massive concentration of phosphorous as it is a required nutrient for their growth and as they grow to colossal sizes they have a dual negative effect on the water they inhabit. The first effect is drastically lowering the amount of oxygen within the water supply, which eventually kills all of the fish that inhabit it and the second is that many species of algae that form in these blooms also secrete toxins into the…

and Phosphorus are together the eutrophication will occur. This was shown in jars 2 and 4. One could argue that herbicides are worse in water than fertilizer. As stated in another study when herbicides get into water it does not always cause algae blooms but the algae that does grow there is a new strand and is referred to as “super algae”, algae that has adapted and will be harder to kill. The study referred to them as mutants. The study says “Rare, pre-selective mutations may allow the…

Toxicity Testing and Determining the LC50 Introduction This report discusses an experiment of Toxicity test done in Richland lab to determine the LC50, a test that is used to find out what concentration of a substance in this case household chemicals that will kill 5o percent of the population of the brine shrimps, with the exposure household chemicals such as , Ammonia, Bleach, and Vinegar, and the morality with each solutions. I and my group splitte the Brine shrimps into 4 containers,…

neurotoxin has been found in many new shellfish. Phytoplankton produces a natural acid called Domoic acids which in small doses it's harmless. However, when it is produced in excess it becomes poisonous to people. "The shellfish that eat these algae blooms don't seem to be affected by the toxin," said Morgaine McKibben, a Ph.D. student at the University of Oregon. But when other animals eat the shellfish they are affected in a very negative way. When it is ingested, it can…

Not often does a decision made by a director due to lack of funds create an end result that critics will continue discussing for nearly a century. However German director Fritz Lang, made such a decision for his 1931 film, M. Partly due to monetary constraints, and partly due to feelings that his own artistic vision would be compromised by including sound in his piece, the end result was a film with roughly a third in total silence. No film, as of yet, quite encapsulates the deafening power of…

“Nothing happens. Nobody comes, nobody goes. It's awful.” This quote extracted from Waiting for Godot, an absurdist play by Samuel Beckett that premiered on 5 January 1953, holds the essence of absurdist theatre and what its playwrights seek to express- the inescapable meaningless and futility of life. The origins of absurdist theatre are commonly linked to the avant-garde experimentations of the 19th century, but there has been speculation that there were traces of absurdist theatre in works…

exactly does the title mean and what the soldier is and what the soldier has become. Hemingway portrays a setting in which the soldier is trapped and no longer can escape due to past experiences and drastic changes in his life. Harold Krebs also referred to as “Hare”, “Harold”, and “Krebs” is a hard fighting solider who fought for his country and now is suffering after coming home. He who served for his country out of bravery now has become this creature that can’t leave his past wounds and…
