Parallel evolution occurs when a similar trait emerges in independent evolutionary lineages. Although changes in protein coding and gene transcription have been investigated as underlying mechanisms for parallel evolution, parallel changes in chromatin structure have never been reported. Here, Saccharomyces cerevisiae and a distantly related yeast species, Dekkera bruxellensis, are investigated be
Data driven studies of heavy-ion results has played a big role in highlighting interesting features of these complex systems. In this proceeding, a simple QGP-brick interpretation of the RAA and v2 at high pT (pT≈10 GeV/c) is presented. This interpretation draws attention to two fundamental questions: is there an effect of the asymmetric QGP expansion on the v2 at high pT? is there an energy loss
In the process of understanding nuclear collisions, reliable extrapolations from pp collisions, based on Glauber models, are highly desirable, though seldomly accurate. We review the inclusion of diffractive excitations and argue that they provide an important contribution to centrality observables in pA collisions. We present a method for distinguishing between diffractively and non-diffractively
Steam-diluted combustion in gas turbine systems is an effective approach to control pollutant emissions and improve the gas turbine efficiency. The primary purpose of the present research is to analyze the influence of steam dilution on the combustion stability, flame structures, and CO emissions of a swirl-stabilized gas turbine model combustor under atmospheric pressure conditions. The premixed
This paper compares the signal-to-noise ratio obtained using an InSb photodiode for infrared (IR) polarization spectroscopy to that obtained using an upconversion detector, and shows a factor 64 improvement by the change. Upconversion detection is based on using sum frequency generation to move the IR optical signal to near-visible wavelengths to improve the sensitivity.
Diode laser-based two-line atomic fluorescence (TLAF) thermometry applied to flames of combusting wood pellets is demonstrated. The temperature above burning wood pellets placed in the hot product gas of gallium seeded laminar flames is measured. The calibration-free technique provides spatially resolved temperatures in one dimension with sufficient temporal resolution to resolve all combustion st
In many ways can Thomas More’s vision in his classic Utopia from 1516 lend itself to describe Sweden as no longer a great power in war, as had been the case in the 17th and early 18th century, but an egalitarian nation and also in other aspects a peaceful, humanitarian example to follow. The ideal that More envisioned is to be understood as an unattainable and therefore unrealistic dream; his idea
This report presents a meticulous review of the background of today’s flow-based society and its vulnerability. Furthermore, there is a discussion about how to define flow-based disruption risks, and how their consequences, including the domino effects, can be described. Also the theory areas, addressing this kind of risks, are treated in this report. The modern society of today is, to a great ext
This report presents an idea generator which is intended to be used when searching for new options for handling the disruption risks of the company. The initial step of the search is usually characterized as a “brainstorming session”, i.e. to generate as many risk management options as possible, and preferably untraditional ones. This is where the idea generator may be of great assistance; it cons
In this report the risk management process is presented as consisting of 14 different steps and each step is described and discussed. Also widened aspects on the risk management process are treated, as well as the economic significance. The modern society of today is, in many respects, a vulnerable society and to a great extent built up round supply chains. In these strictly integrated chains, wit
