Web usage mining (WUM) is the process of extracting navigation behaviour patterns that allow analysing users' interactions with Web-based environments. We discuss the impact of developing the WUM preprocessing phase according to concepts, problems and goals specific to Web-based learning environments. We present a tool prototype that automates typical tasks(More)
Chemical synthesis, functional reconstitution, and electron paramagnetic resonance (EPR) have been used to analyze the structure and function of phospholamban (PLB), a 52-residue integral membrane protein that regulates the calcium pump (Ca-ATPase) in cardiac sarcoplasmic reticulum (SR). PLB exists in equilibrium between monomeric and pentameric forms, as(More)
