Blu-ray Disc Blu-ray Disc (BD) is an optical disc storage medium designed to supersede the DVD format. The plastic disc is 120 mm in diameter and 1.2 mm thick‚ the same size as DVDs and CDs. Blu-ray Discs contain 25 GB per layer‚ with dual layer discs (50 GB) being the norm for feature-length video discs. Triple layer discs (100 GB) and quadruple layers (128 GB) are available for BD-XL re-writer drives.[2] The major application of Blu-ray Discs is as a medium for video material such as feature

To call Charles Ray: Sculpture‚ 1997-2014 at the Art Institute of Chicago sparse is both an over and understatement. The exhibition on the Chicago-born‚ Los Angeles-based sculptor dedicates an entire half of the Modern Wing’s second floor to a mere nineteen different sculptures. Based on the exhibit’s title and the sheer size of the rooms that they gave to these pieces‚ it is as if they are trying to edify the viewer to Ray’s value as a contemporary artist. However‚ as you go through the exhibition

Gamma Rays in Radiotherapy 8B Lae Eun Kim In this unit‚ we learned that there are 7 types of radiation of the electromagnetic spectrum – gamma rays‚ x-rays‚ ultraviolet‚ visible spectrum‚ infrared‚ microwaves and radio waves. With different wavelengths‚ they each have different properties and uses. Gamma rays are the radiation with the smallest wavelengths – 10-12m to 10-10m – and the most energy and the most danger of any wave in the electromagnetic spectrum. Radiotherapy‚ a treatment the use

Principles of X-ray Diffraction Diffraction effects are observed when electromagnetic radiation impinges on periodic structures with geometrical variations on the length scale of the wavelength of the radiation. The interatomic distances in crystals and molecules amount to 0.15–0.4 nm which correspond in the electromagnetic spectrum with the wavelength of x-rays having photon energies between 3 and 8 keV. Accordingly‚ phenomena like constructive and destructive interference should become observable

The person that has been selected for the basis of this paper is Ray Lewis‚ a twelve year pro-bowl selection linebacker from the Baltimore Ravens. The reason I have chosen Lewis for this paper is because of the qualities he has as a leader not only on the playing field‚ but off of it as well. He is what I believe to
