Protein Separation Using Gel Filtration Chromatography Introduction: Chromatography techniques are one of the most useful methods use for the isolation or separation of macromolecule from a mixture. The most common used chromatography techniques are thin -layer chromatography (TLC), column chromatography, etc. The purpose of this lab exercise is using the gel filtration chromatography to separate different proteins from a mixture based on their size. Also, collecting elutes that run through…

and melt over a wide range of temperatures. Crystalline solids, or crystals, have distinctive internal structures that in turn lead to distinctive flat surfaces, or faces. The faces intersect at angles that are characteristic of the substance. When exposed to x-rays, each structure also produces a distinctive pattern that can be used to identify the material. The characteristic angles do not depend on the size of the crystal; they reflect the regular…

How is it that magic works? Basic science, and some different uses of common items can make anything possible. Take for example, pictures in magic. In Harry Potter and the Sorcerer’s Stone, by J. K. Rowling, paintings in the world of magic are not still images, but rather LCD screens, which are connected to a live feed camera, so that those that are pictured can live their lives normally without having to sit in a picture all day. With some research that I’ve done with digital frames, I will…

‘The Advantages of Being a Woman Artist’ One contemporary artwork that is on display at the Tate Gallery that uses the postmodern frame to comment on the inequality between men and women is a poster created by the Guerrilla Girls titled, ‘The Advantages of Being a Woman Artist’. Their piece uses styles of comedy including ironic and sarcastic humour by outlining the “benefits” of being a female artist. This chosen artwork is one of thirty pieces created by the group in a portfolio entitled…

form a liquid. They would then purify the colored enamel liquid to eliminate impurities from it. Using something similar to a modern day paintbrush, like a sharpened quill, the metal worker would color the carved in design with different colored enamels producing the bright colors on the chasse. After the enamel was colored onto the copper, the copper is then placed in a high temperature container called kiln that reaches temperatures of about 1000 degrees Celsius. This allowed for the liquid…

Krabbe Disease According to the National Institute of Neurological Disorders and Stroke, “Krabbe Disease is a rare, inherited degenerative disease” (NINDS.nih.gov). It is diagnosed when a presence of globoid cells are found. Those are cells with more than one nucleus. A nucleus is like the brain of the cell where all the action happens. This disease breaks down the coating of nerve fibers or axons, those are called Myelin Sheath. This disease also breaks down brain cells which are imperative…

piezoelectric crystals. When an electrical current from the machine is applied to these crystals, they rapidly change shape. The changes in shape cause vibrations of the crystals, producing ultrasound waves that travel outward. The sound waves then pass through the patient’s skin and into his or her internal anatomy. Sound is a wave that travels in a straight line and requires a medium. Frequency and wavelength are related by the speed of sound in the medium with (v=fλ). V is usually slowest in…

People started using television in the 1940’s. Television makes people feel like they are viewing live events. Television took years of innovation. In the beginning the importance of was ignored as people didn’t really need television in their day to day lives. In 1872, Joseph May, was examining materials for use in for the first transatlantic cable placed a strand of selenium wire on a table near a window and noticed that sunlight caused the electrical conductivity of the wire to change .He…

below the Earth’s surface (Coal and its Uses). While some large surface mines can cover many squares kilometers in area and have the advantage of lower mining costs in comparison to underground mining (Coal and the Environment). Figures 7 and 8 below display a surface coal mine and an underground coal mine respectively. Figure 7. Surface coal mine Figure 8. Inside of an underground coal mine After coal is mined it needs to be processed, first, the coal is washed or cleaned to remove…

us with feedback and tells us “what’s going on in our neighborhood.” There are multiple areas that televisions help us, for instance without televisions we would have never had telecommuting, cellphone displays hence no touch screens, or any type of inventions that contain liquid crystal displays. Furthermore television has not only affected us socially, but technologically, economically, and…
