    Potassium channels (KC) are selective transmembrane proteins that allow K+ ions flow down an electrochemical gradient across cell membrane, thus controlling plasma membrane potential in both excitable and non-excitable cells (Szabo, Zoratti&Gulbins, 2010). Evolutionarily conserved KC family is one of the larges and most diverse of ion channels (Table1). Its diversity comes not only from a large number of genes coding for main subunits (over 80 mammalian genes). Many other processes such as…

    ferrocyanide. Using cyclic voltammetry a calibration curve will be created to determine the concention(mM) of an unknown solution of ferricyanide. In cyclic voltammetry, the potential of a substance is scanned starting from a certain voltage, going to another voltage, and then returning to the original, hence “cyclic” voltammetry. As current changes, a triangular waveform is created which looks like an upside down V. Using this triangular waveform, a voltammogram can be made by plotting…

    Physical Security As Margaret Rouse of TechTalk.com stated, “Physical security is the protection of personnel, hardware, programs, networks, and data from physical circumstances and events that could cause serious losses or damage to an enterprise, agency, or institution. This includes protection from fire, natural disasters, burglary, theft, vandalism, and terrorism.” In the world we live in today physical security is often over looked (Rouse, 2005). News organizations sensationalize the…

    piece of Si with a (004) reflection plane and a Si powder sample are scanned, as well as the peaks the locations of the diffraction peaks on the single crystal. The collected data is then analyzed to determine the criteria for planes to produce a spike in energy by plotting in reciprocal space. This experiment serves to illustrate the importance of reciprocal space. It also introduces the ideas of glancing incidence and exit. Theory The basis of x-ray diffraction is rooted in understanding the…
