Vibrationally resolved C1s photoelectron spectra of benzene and d(6)-benzene have been recorded using monochromated synchrotron radiation at photon energies of 330 eV. The spectrum of normal benzene displays considerable vibrational structure. Particularly noteworthy is the strong excitation of a combined CCH-bending and CC-stretching mode which splits the main peak into two well-defined maxima. I
This report is part of the educational programme of Fire Protection Engineering at the Department of Fire Safety Engineering at Lund University. The following report is a fire safety evaluation of Falkhallen with purpose of evaluating personal safety considering evacuation in case of fire. Falkhallen is an arena which hosts school activities and a variety of events. A number of worst likely f
Parton showers have become a standard component in the description of high-energy collisions. Nowadays most final-state ones are of the dipole character, wherein a pair of partons branches into three, with energy and momentum preserved inside this subsystem. For initial-state showers a dipole picture is also possible and commonly used, but the older global-recoil strategy remains a valid alternati
Course evaluation 2019: GEOM09 Summary based on three students 1. How did you perceive the course in general (from 1-5, where 1 is poor and 5 is excellent)? (1) (2) (3) (4) 33% (5) 67% 2. How did you perceive the level of the course (from 1-5, where 1 is too simple and 5 is too difficult)? (1) (2) (3) 33% (4) 67% (5) 3. How easy was it to keep your level of interest up during the course (from 1-5,

A new isotope shift program, part of the multiconfiguration Hartree-Fock (MCHF) atomic structure package, has been written and tested. The program calculates the isotope shift of an atomic level from MCHF or configuration-interaction (CI) wave functions. The program is specially designed to be used with very large CI expansions, for which angular data cannot be stored on disk. To explore the capac
This work presents an analysis of phase noise in the 1/f(2) region displayed by both single-ended and differential bipolar Colpitts oscillators. Very accurate and rigorous symbolic phase noise expressions are derived, enabling a deeper insight into the major mechanisms of phase noise generation, and providing new tools for design optimization. Phase noise expressions for the cross-coupled differen
Aims: Using a longitudinal approach, the aim of this study was to examine whether baseline engagement in arts and culture was associated with a decline from ‘Good’ to ‘Poor’ health at follow-up. Methods: Self-rated health (SRH) and engagement in six cultural activities among randomly selected Danish adults (⩾15 years) were assessed using data from the Danish Health and Wellbeing Survey in 2019. On
It was with great interest that I read “Political Power of Iranian Hierocracies” by János Jany published in Comparative Civilizations Review. Writing about Iranian history is not an easy task because historical points of view have been highly politicized. Such is particularly the case when discussing the Pahlavi dynasty, particularly its founder, Reza Shah Pahlavi, and his successor, Mohammed Reza
In this study, the authors investigate the resistance of Boolean functions against fast algebraic attacks and deduce a bound between fast algebraic immunity and higher-order non-linearity (it is the first time that a bound between these two cryptographic criteria is given). The authors then show that the fast algebraic immunity of the following two classes of Boolean functions is not good: (a) The
Laminar burning velocities of acetone + air mixtures at initial gas mixture temperatures of 298, 318, 338 and 358 K are reported. Non-stretched flames were stabilized on a perforated plate burner at 1 atm, and laminar burning velocities were determined using the heat flux method, at conditions where the net heat loss from the flame to the burner is zero. The overall accuracy of the burning velocit
