Application of Fluorescence Spectroscopy in Chemical Oceanography: Tracing Colored Dissolved Organic Matter (CDOM) Erika Mae A. Espejo 3rd year‚ BS Chemistry‚ University of the Philippines‚ Diliman Abstract Dissolved organic matter (DOM)‚ the fraction passing through a 0.45 µm membrane filter‚ is considered poorly understood mixture of organic polymers because of its complexity. Although it largely influences a lot of biogeochemical processes in aquatic environments‚ its characterization is not

Have you ever thought that perhaps‚ the only colour in real life is white? White light is indeed the bearer of all colours. The colours we see are reflections bouncing off an object or are the light source itself. The light sources change and the colours with them. Colour is not a stable affair. Colour is light alone‚ but our experience is so direct that we trust our eye and believe that a colour is inherent to an object. Imagine living in a world where everything is white in colour! However‚

Making things look bigger When you use an optical instrument‚ whether it be something very simple like a magnifying glass‚ or more complicated like a telescope or microscope‚ you’re usually trying to make things look bigger so you can more easily see fine details. One thing to remember about this is that if you want to make things look bigger‚ you’re always going to use converging mirrors or lenses. Diverging mirrors or lenses always give smaller images. When using a converging lens‚ it’s helpful

Introduction Light exhibits both the properties of a wave and a particle. Its wave-like properties are best shown in its propagation while the particle-like properties in the emission and absorption of light.[1] As light behaves like a wave‚ superposition is observed between interacting waves. Superposition of waves is the addition of waves that travel across the same medium. The resulting wave from this addition has amplitude at a particular point that is the algebraic sum of the amplitudes of

Kevin Chapman ARTH 2720-001 Term Paper December 5‚ 2012 Manet and The Bar Edouard Manet’s painting A Bar at the Folies-Bergere‚ was completed in 1882 and is considered his last great painting. He displayed it at the Paris Salon just one year before his passing. This painting as vexed art historians throughout the years for its complex visual subject matter and leaves Manets true interpretation of his painting in the air for discussion. Although there are many interpretations‚ A Bar at the Folies-Bergere

Mirror and Magnification Equations The mirror equation expresses the quantitative relationship between the object distance (do)‚ the image distance (di)‚ and the focal length (f). The equation is stated as follows: [pic] The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (hi) and object height (ho). The magnification equation is stated as follows: [pic] These two equations can be combined to yield information about the

Project – “Stereo Audio Compressor” Starting speech Audio compressors that use a light source to control a Light Dependent Resistor (LDR) are not new‚ and indeed there are many classic optical compressor designs. The design goal of the SOC-1.1 was to further enhance the attributes of optical compression to provide the user with alot more functionality as well as improve the compressor response to real world audio signals. We have carefully examined the characteristics of the LDR and developed
