Exploring the boundaries of the nuclear landscape : α-decay properties of 211Pa
2020
Employing the recoil ion transport unit (RITU) and a fusion-evaporation reaction, the α decay of 211Pa has been identified via the implantation-decay correlation technique through observation of chains up to four consecutive decays. An α-particle energy and half-life of 8320(40) keV and 3.8+4.6−1.4 ms, respectively, were measured, corresponding to favored α decay. In addition, more precise α-decay properties of 212Pa and 213Pa were obtained due to accumulated statistics. The present data were compared to those predicted by selected atomic mass models and it was used to estimate the possibility of observing proton emission from these isotopes. peerReviewed

Single-particle and collective excitations in the transitional nucleus 166Os
2021
The mean lifetimes of the lowest energy 2+, 8+ and 9− states in 166Os have been measured using the recoil distance Doppler-shift method in conjunction with a selective recoil-decay tagging technique. These measurements extend studies into the most neutron-deficient mass region accessible to current experimental methods. The B(E2; 2+ → 0+) = 7(2) W.u. extracted from these measurements is markedly lower than those observed in the heavier even-mass Os isotopes. The 8+ and 9− states yield reduced transition probabilities that are consistent with single-particle transitions. While these values may indicate a departure from collective structure, the level scheme and the underlying nuclear configu…
Cannabis for Cognitive Enhancement as a New Coping Strategy? Results From a Survey of Students at Four Universities in Germany
2016
Cognitive Enhancement (CE) is often discussed in relation to stimulant drugs, such as amphetamines (AMPH). However, there is some evidence that cannabis (CAN) can be used for CE.This study compares the knowledge, prevalence, and perceived effects of and factors associated with the knowledge of or use of CAN versus AMPH for CE among undergraduate students at four German universities.A survey was taken of 1,538 students at four German universities. It investigated their knowledge and use of CAN and AMPH for CE as well as associated factors. Descriptive and analytic (Mann-Whitney-U test, Fisher's exact test, logistic regression) statistics were obtained using SPSS.Responses were obtained from …
The Nordic Paradox and intimate partner violence against women (IPVAW) in Sweden: A background overview
2019
The global public health problem of intimate partner violence against women (IPVAW) is typically tied to gender inequality. Contrary to what would be expected, however, a 2012 survey conducted by the European Union Agency for Fundamental Rights (FRA) showed lifetime prevalence rates of IPVAW in the Nordic countries which were among the highest of the 28 EU member states, despite these countries being rated as some of the most gender‐equal in the world. The aim of this article is to enable a furthered understanding of this Nordic Paradox through providing an overview of knowledge about IPVAW in Sweden in relation to the apparent paradox. It assembles information on IPVAW prevalence, on Swede…

The purpose of this study was to investigate the prevalence of self-reported restrictive eating, current or past eating disorder, and menstrual dysfunction and their relationships with injuries. Furthermore, we aimed to compare these prevalences and associations between younger (aged 15–24) and older (aged 25–45) athletes, between elite and non-elite athletes, and between athletes competing in lean and non-lean sports. Data were collected using a web-based questionnaire. Participants were 846 female athletes representing 67 different sports. Results showed that 25%, 18%, and 32% of the athletes reported restrictive eating, eating disorders, and menstrual dysfunction, respectively. Higher ra…
The prevalence of bipolar disorders in the general population - a growing trending topic?
2015
report the first meta-analysis of theprevalence of bipolar disorder (BD) from population-based studies. Strengths of the manuscript include theuse of suitable methods of analysis, reporting both annualand lifetime prevalence rates, and providing separatedata for bipolar subtypes I and II. The latter is relevantbecause type II is not simply a milder or minor form of BD.This publication is of considerable interest, firstlybecause it confirms that the frequency of BD in thegeneral population is low and closer to the conservativeestimates of 1-2%, as suggested by historical data.
Incidence and lifetime prevalence of Bell's palsy in two Sicilian municipalities
1996
Introduction - In a door-to-door two-phase survey of common neurologic diseases conducted in two Sicilian municipalities, we investigated the incidence and the lifetime prevalence of Bell's palsy (BP). Material & methods - During phase 1, we administered a screening instrument for facial palsy to 11,901 adult persons. During phase 2, study neurologists using specified diagnostic criteria evaluated those subjects who screened positive. Results - We found 73 subjects who had experienced BP during their life. The lifetime prevalence as of November 1, 1987, was 642.8 cases per 100,000 population age 15 years and above. The prevalence increased with age and was similar in men and women. Eighteen…
