Analysis of selected nutraceuticals by liquid chromatography
No full text39 ABSTRACT Charles University, Faculty of Pharmacy in Hradec Králové Department: Department of Pharmacognosy and Pharmaceutical Botany Candidate: Laureen Reda Youssef Ibrahim Supervisor: RNDr. Jaroslav Jenčo, Ph.D. Title of dissertation thesis: Analysis of selected nutraceuticals by liquid chromatography The extract obtained pellets of Humulus Lupulus L. var Columbus was subjected to a phytochemical study and isolation of its bitter acid constituents. The summary extract was separated into individual fractions by liquid-liquid extraction. After performing HPTLC, GC-MS, and LC-MS analysis, the fraction HL-Hex B was selected and purified further by preparative chromatography. A monocomponent pale yellow solid substance of lupulone was obtained after the final preparative separation. Based on instrumental analysis by reversed phase HPLC with core-shell particles, the analyte was compared to the extract of dietary supplement HopsVital where the presence of bitter acids in the supplement was shown. Key words: nutraceuticals, high performance liquid chromatography, sample preparation, modern stationary phase

Solar Eclipse Monitoring for Solar Energy Applications Using the Solar and Moon Position Algorithms
No full textThis report includes a procedure for implementing an algorithm (described by Jean Meeus [1]) to calculate the Moon’s zenith angle with uncertainty of ±0.001° and azimuth angle with uncertainty of ±0.003°. The step-by-step format presented here simplifies the complicated steps Meeus describes to calculate the Moon’s position, and focuses on the Moon instead of the planets and stars. It also introduces some changes to accommodate for solar radiation applications. These include changing the direction of measuring azimuth angles from north and eastward instead of from south and eastward, and the direction of measuring the observer’s geographical longitude to be measured as positive eastward from Greenwich meridian instead of negative. In conjunction with the solar position algorithm that Reda and Andreas developed in 2004 [2], the angular distance between the Sun and the Moon is used to develop a method to instantaneously monitor the partial or total solar eclipse occurrence for solar energy applications and smart grid users. This method can be used in many other applications for observers of the Sun and the Moon positions for applications limited to the stated uncertainty

What Does It Mean to Say That Procedure Is Political?
No full textProcedure is not the first field of law to face controversy along these lines. Law’s independence from politics, in both its descriptive and normative aspects, is a century long legal challenge.9 This Article aims to clarify what we mean when we characterize procedure as political, as well as to understand some of the harms generated by failing to confront and acknowledge the political. This is a preliminary step in approaching future formulations of procedural rules if they cannot be depoliticized
Interview with Murad Ibrahim Desouki and Khadija Maman and Alia Reda and Ahmed Al-Samanudi
