The relationship between visible light emission and species fraction of the hydrogen ion beams extracted from 2.45 GHz microwave discharge.
2015
The relationship between Balmer-α and Fulcher-band emissions with extracted H + , H + 2 , and H + 3 ions is demonstrated for a 2.45 GHz microwave discharge. Ion mass spectra and optical measurements of Balmer-α and Fulcher-band emissions have been obtained with a Wien Filter having an optical viewport on the plasma chamber axis. The beam of approximately 1 mA is analyzed for different plasma conditions simultaneously with the measurement of light emissions both with temporal resolution. The use of visible light emissions as a valuable diagnostic tool for monitoring the species fraction of the extracted beams is proposed. peerReviewed
The Hamburg/ESO R-process Enhanced Star survey (HERES)
2004
We report on a dedicated effort to identify and study metal-poor stars strongly enhanced in r-process elements ([r/Fe] > 1 dex; hereafter r-II stars), the Hamburg/ESO R-process Enhanced Star survey (HERES). Moderate-resolution (~2A) follow-up spectroscopy has been obtained for metal-poor giant candidates selected from the Hamburg/ESO objective-prism survey (HES) as well as the HK survey to identify sharp-lined stars with [Fe/H] < -2.5dex. For several hundred confirmed metal-poor giants brighter than B~16.5mag (most of them from the HES), ``snapshot'' spectra (R~20,000; S/N~30 per pixel) are being obtained with VLT/UVES, with the main aim of finding the 2-3% r-II stars expected to be a…
Postmodern Business Ethics - Is It Possible, Is It Relevant?
1998
Ethics as a general philosophy and doctrine of good life and action has penetrated also the field of economic research. This application has been called business ethics. In the wide sense it concentrates on studying the practices of business life from the moral point of view. It criticizes, studies, and tries to give instructions.
Motherhood‐induced gene expression in the mouse medial amygdala: Changes induced by pregnancy and lactation but not by pup stimuli
2021
During lactation, adult female mice display aggressive responses toward male intrud-ers, triggered by male- derived chemosensory signals. This aggressive behavior is not shown by pup- sensitized virgin females sharing pup care with dams. The genetic mechanisms underlying the switch from attraction to aggression are unknown. In this work, we investigate the differential gene expression in lactating females ex-pressing maternal aggression compared to pup- sensitized virgin females in the me-dial amygdala (Me), a key neural structure integrating chemosensory and hormonal information. The results showed 197 genes upregulated in dams, including genes encoding hormones such as prolactin, growth h…
Insight into particle production mechanisms via angular correlations of identified particles in pp collisions at √s = 7 TeV
2017
Two-particle angular correlations were measured in pp collisions at s√=7 TeV for pions, kaons, protons, and lambdas, for all particle/anti-particle combinations in the pair. Data for mesons exhibit an expected peak dominated by effects associated with mini-jets and are well reproduced by general purpose Monte Carlo generators. However, for baryon–baryon and anti-baryon–anti-baryon pairs, where both particles have the same baryon number, a near-side anti-correlation structure is observed instead of a peak. This effect is interpreted in the context of baryon production mechanisms in the fragmentation process. It currently presents a challenge to Monte Carlo models and its origin remains an op…
ALHAMBRA Ks band selected catalogue
2017
Galaxy formation and evolution are an essential part of astronomy and cosmology today. To better understand the processes that are involved in the mechanism behind them it is necessary to study the physical processes in the observable universe at different epochs, which requires large astronomical surveys. In the case of the ALHAMBRA Survey, near infrared images (NIR) provide extra information that significantly increases the scientific value of the data, particularly for strongly-reddened elliptical galaxies, AGN or moderate-redshift starburst galaxies. The selection in the optical band F814W (used for ALHAMBRA’s original catalogue in Molino et al. (2014)) creates a bias against intrinsica…
Desired cybersecurity skills and skills acquisition methods in the organizations
2022
Abstract:Key personnel and their competences play important roles in continuity management and improving resilience of cybersecurity in organizations. Researchers have addressed many topics and studies in the cybersecurity domain. However, relevant cybersecurity skills and acquisition of them in expertise development, have only been partially touched. If designed systematically and properly, cybersecurity training can improve cybersecurity expertise to ensure better performance in complex cybersecurity situations. More through study on the acquisition of cybersecurity skills, and work-life needs are needed. The research three questions of this study are: How do work-life representatives see…
Vote buying and Its effect on democracy and development in Uganda : a case of Rwamucucu Sub-County, Kabale District, South Western Uganda
2016
Master thesis development management - University of Agder 2016 In this study, I have investigated vote buying and vote selling as a phenomenon in Uganda, using Rwamucucu Sub-County as a case. The major aim has been to understand local people’s perception of vote buying and selling and its effect on democracy and development. I have utilized a qualitative research strategy, using mainly semi-structured interviews, focus group discussions and field observations. The data were collected during the time of the 2016 Uganda general elections. Results indicate that vote buying has been extensive in Rwamucucu, and that it had increased significantly during the last 20 years. The study also shows t…
Vingrinājumu kopa kaligrāfijas pamatu apguvei profesionālās ievirzes mākslas skolā
2022
Diplomdarba mērķis ir izstrādāt vingrinājumu kopu kaligrāfijas pamatu apguvei, aprobēt un analizēt to, atbilstoši profesionālās ievirzes mākslas skolu programmas prasībām. Lai apgūtu kaligrāfiju, ir jāatpazīst burtu elementi, jāvingrina rokas muskulatūra, jāprot izmantot platgala un asgala instrumentus. Autore piedāvā vingrinājumu kopu dažādu instrumentu un materiālu pielietojumu kaligrāfijas pamatu apguvei. Diplomdarba pirmajā daļā autore skaidro kaligrāfijas jēdzienu un ieskicē kaligrāfijas attīstības gaitu, apraksta kaligrāfiju kā dažādu kultūru sastāvdaļu, min slavenākos kaligrāfus pasaulē un Latvijā, kā arī ieskicē „trīs vaļus”, uz kuriem balstās un kurus pielieto kaligrāfijā: spalvu, …
Regulating (and Self-regulating) the Sharing Economy in Europe: An Overview
2018
The article describes the main legal challenges for regulating the sharing (or collaborative) economy in Europe and explains how the existing body of EU law applies to these new business models. In the last part, it makes a few brief comments on the need for future regulation.
