The determination of biogenic amines in alcoholic beverages is important to assess the potential risks associated with the consumption of high concentrations of these compounds. In addition, product storage conditions and the length of storage can cause the formation of biogenic amines that reduce product quality. We report a new method using cation-exchange chromatography with either suppresse...

BACKGROUND With our aging population and limited number of geriatric psychiatrists, innovations must be made in order to meet the growing demands for geriatric psychiatry services. Emerging technologies could greatly improve access to care and systematic data collection. METHODS This randomized study compared completion rates and time to completion (primary outcomes) when using iPad technolog...

Type III secretion (T3S) systems are used by numerous Gram-negative pathogenic bacteria to inject virulence proteins into animal and plant host cells. The core of the T3S apparatus, known as the needle complex, is composed of a basal body transversing both bacterial membranes and a needle protruding above the bacterial surface. In Shigella flexneri, IpaD is required to inhibit the activity of t...

Abstract The motion of a toppling iPad is analyzed in detail. Measurements angular velocity and linear acceleration were made for about the edges corners. From analysis velocity, position center mass gyration radii determined. accelerometer was measured using both centrifugal Euler acceleration, with latter measurement providing more accurate data. This experiment could be used first year unive...

One of the most significant influences on student engagement is the teacher’s pedagogical practices, including the incorporation of technology into the teaching and learning of mathematics. This paper reports on a qualitative study investigating how the incorporation of iPads into a Year 3 primary classroom during a six month trial influenced teaching and learning practices and student engageme...

This article describes the design of three distinctive data collection instruments that an education institution can implement to measure teaching and teachers’ perceptions as a largescale transformative mobile learning program is launched on a campus. Our primary goal is to review how one college within a system of 20 campuses engaged faculty in the early stages of a national mobile learning p...

BACKGROUND Providing patient information to physicians in usable form is of high importance. Electronic presentation of patient data may have benefits in efficiency and error rate reduction for these physician facing interfaces. Using a cancer symptom measurement tool (the MD Anderson Symptom Inventory (MDASI)) we assessed the usability of patient data in its raw paper form and compared that to...
