In experiment 1 there were five cuvettes of decreasing concentrations from the initial 0.01 mg/ml concentration of Fast Green solution (cuvette 1). The diluted concentration of cuvettes #2 through #5 were calculated using the dilution formula, C1V1 = C2V2 ; the calculations for the dilute concentrations are in Results section. The concentration for each tube were as follows: 0.015 mg/ml for tube 1, 0.0075 mg/ml for tube 2, 0.00375 mg/ml for tube 3, 0.001875 mg/ml for tube 4, and 0.000935 mg/ml…

the good and evil present in the world. Lightness represents day, whereas darkness signifies night. The light we see…

shadow ” (Stadler and McWilliam 24). In this scene expresses Mr.Chow’s life of emptiness. Another instance is when Mr.Chow and Mrs. Su go to the dark alleys, the light is a low-key illumination, and it expresses both of deep sorrow. Therefore, low-key illumination shows character’s negative emotion in this movie. On the other hand, high key light expresses his hope, because “It produces a fairly bright image with high visibility, graduated…

waves as we strolled along beside the water, taking in the breath-taking scenery. There had been a faint mist acting as a blanket covering the city of Chicago. Many friends and families were taking in the beautiful scenery that the city had been emitting as they strolled along the streets or maneuvered across the marinas. My parents, siblings, and I followed the trail that lay near the rear end of the Adler Planetarium. “Maybe we should head back home,” my mother complained, “I told you we…

This semester I worked in the Scene Shop for Production Experience 1 for both Vinegar Tom and Dead Man’s Cell Phone. Because I came on later than the rest of my peers, I caught the tail-end of work for Dead Man’s Cell Phone. I also participated in light hang and strike for Vinegar Tom as part of my Production Experience this semester. In terms of scene shop, it was new for me because I had never spent such a concentrated amount of time in that aspect of production or worked on projects on such a…

Lighting The lights are the first thing the audience experience in this piece, then comes sound and movement. From the begging the lighting design was unique in the since that there was emphasis on the curtains. There were lights shining directly on the wings drapes. They were simply horizontal lines stacking straight up. The choice to have the lights show up first gave the audience time to take in the lights and create their own idea of what the lights represented. There were two sets/types of…

achieving this knowledge, we furthered our understanding of photosynthetic reactions by and experimenting with the factors that affect photosynthesis, which are light intensity, pigments, and light wavelength. By experimenting with these factors, our group was able to create an action and absorbance spectrum, which allowed us to determine which light wavelengths do the pigments in plants respectively absorb for photosynthesis. This allowed us to fully understand what conditions photosynthesis…

Perspective, the most powerful thing on earth. A statement of my own so therefore not entirely factual, but true none the less. The very definition of perception is, “The way you think about or understand someone or something (Unknown, 2016)”. Is this not the very thing that causes us to take sides in conflict or to act on something that doesn’t seem right? We are not born with the understanding that “White is Right” we are taught this from a very young age by our predecessors; our parents, our…

Spectrophotometry is a method in which organic and inorganic substances are identified or characterized by the use of electromagnetic radiation. Electromagnetic radiation not only includes light (or photons), but thermal energy as well. While the electromagnetic spectrum consists of wavelengths between gamma radiation and the Far IR, most spectrophotometric methods rely on the UV and visible region. In order to use spectrophotometric methods, the sample being analyzed must be able to absorb the…

Racism is something that has been something occurring in the world for a very long time. The novel Heart of Darkness by Joseph Conrad represents the time period of imperialism; when Belgium colonized the Congo. Conrad depicts the racism that occured in the Congo of Africa because of the Europeans colonization. The main protagonist named Marlow, a European sailor, goes on an adventure with his crew through his perspective going up the Congo River with the goal of meeting an idealistic man, Kurtz.…
