Measurement of the first ionization potential of lawrencium (element 103)
2015
Lawrencium, with atomic number 103, has an isotope with a half-life of 27 seconds; even so, its first ionization potential has now been measured on an atom-at-a-time scale and agrees well with state-of-the-art theoretical calculations that include relativistic effects. The most dramatic modern revision of Mendeleev's periodic table of elements came in 1944 when Glenn T. Seaborg placed a new series of elements, the actinides (atomic numbers 89–103), below the lanthanides. In this issue of Nature, Yuichiro Nagame and colleagues report the first measurement of one of the basic atomic properties of element 103 (lawrencium), namely its first ionization potential. Lawrencium is only accessible vi…
Applying a web-based training to foster self-regulated learning — Effects of an intervention for large numbers of participants
2016
Trainings on self-regulated learning (SRL) have been shown to be effective in improving both competence of self-regulated learning and objective measures of performance. However, human trainers can reach only a limited number of people at a time. Web-based trainings (WBT) could improve efficiency, as they can be distributed to potentially unlimited numbers of participants. We developed a WBT based on the process model of SRL by Schmitz and Wiese (2006) and tested it with 211 university students in a randomized control evaluation study including additional process analyses of learning diaries. Results showed that the training had significant effects on SRL knowledge, SRL behavior measured by…
What Motivates Internet Users to Search for Asperger Syndrome and Autism on Google?
2020
Social campaigns are carried out to promote autism spectrum disorder (ASD) awareness, normalization, and visibility. The internet helps to shape perceptions of Asperger syndrome and autism. In fact, these campaigns often coincide with the increase in searches for both diagnoses on Google. We have two study objectives: to use Google Trends to identify the annual time points from 2015 to 2019 with the highest Google search traffic in Spain for the terms &ldquo
Time trends of human papillomavirus types in invasive cervical cancer, from 1940 to 2007.
2013
Contribution over time of human papillomavirus (HPV) types in human cancers has been poorly documented. Such data is fundamental to measure current HPV vaccines impact in the years to come. We estimated the HPV type-specific distribution in a large international series of invasive cervical cancer (ICC) over 70 years prior to vaccination. Paraffin embedded ICC cases diagnosed between 1940 and 2007 were retrieved from eleven countries in Central-South America, Asia and Europe. Included countries reported to have low-medium cervical cancer screening uptake. Information on age at and year of diagnosis was collected from medical records. After histological confirmation, HPV DNA detection was per…
Human papillomavirus genotype distribution in cervical cancer cases in Spain. Implications for prevention
2011
Objective. Human papillomavirus (HPV) genotype distribution in invasive cervical cancer (ICC) is critical to guide the introduction and to assess the impact of HPV prophylactic vaccines. This study aims to provide specific information for Spain. Methods. 1043 histological confirmed ICC cases diagnosed from 1940 to 2007 from six Spanish regions were assembled. HPV DNA detection was performed by SPF10 broad-spectrum PCR followed by deoxyribonucleic acid enzyme immunoassay and genotyping by reverse hybridization line probe assay (LiPA(25)) (version 1). Results. Of 1043 ICC cases, 904 were HPV DNA positive (adjusted prevalence: 89.1%). The eight most common types, in decreasing order, were HPV …
Survival of male genital cancers (prostate, testis and penis) in Europe 1999-2007: Results from the EUROCARE-5 study
2015
Abstract Background We provide updated estimates of survival and survival trends of male genital tumours (prostate, testicular and penis cancers), in Europe and across European areas. Methods The complete approach was used to obtain relative survival estimates for patients diagnosed in 2000–2007, and followed up through 2008 in 29 countries. Data came from 87 cancer registries (CRs) for prostate tumours and from 86 CRs for testis and penis tumours. Relative survival time trends in 1999–2007 were estimated by the period approach. Data came from 49 CRs in 25 countries. Results We analysed 1,021,275 male genital cancer cases. Five-year relative survival was high and decreased with increasing a…
Time trends of cancer incidence in European children (1978-1997): Report from the Automated Childhood Cancer Information System project.
2006
Within the framework of the Automated Childhood Cancer Information System (ACCIS), time trend analyses for childhood cancer were performed using data from 33 population-based cancer registries in 15 European countries for the period 1978-1997. The overall incidence rate based on 77,111 cases has increased significantly (P<0.0001), with an average annual percentage change (AAPC) of 1.1%. The rising trend was observed in all five geographical regions and in the majority of the disease groups (in order of AAPC): soft tissue sarcomas (1.8%), brain tumours, tumours of the sympathetic nervous system, germ-cell tumours, carcinomas, lymphomas, renal tumours, and leukaemias (0.6%). No change was see…
Trends in gastrointestinal bleeding in the Region of Valencia (2000-2005). Relationship to sales of nonsteroidal anti-inflammatory drugs and acid sup…
2011
Objective: To describe 2000-2005 time trends of prescription for NSAIDs, proton pump inhibitors (PPIs) and hospital admissions for gastrointestinal (GI) bleeding. Methods: Time series analysis of gastrointestinal (GI) bleeding admission and drugs’ Defined Daily Dose per 1000 people per day (DDD/1000/day) in the Region of Valencia, Spain, from January 2000 to December 2005. Results: Dispensation of NSAIDs went from 42.7 DDD/1000 people/day in 2000 to 58.3 DDD/1000 people/day in 2005. During the same period, dispensation of PPIs went from 26.3 DDD/1000 people/day to 68.5 DDD/1000 people/day (both are statistically significant). The rate of hospitalisations for gastrointestinal bleeding during…
Libraries and Intellectual Debate in the Late Republic: the Case of the Aristotelian Corpus
2013
The present chapter explores the catalyzing function of libraries in the intellectual debate of the late Roman Republic, by focusing on the significant case of the Aristotelian esoteric corpus. A careful analysis of the literary and historical evidence concerning the use of Peripatetic texts allows to detect the presence of at least two important libraries containing Aristotle's 'pragmatiai' in Roman Italy: Lucullus' collection in Tusculum and Sulla's one in Cumae. Several Greek and Latin sources bear witness to the vicissitudes of such libraries, and the present paper reassesses their accounts in order to point out the close connection between intellectual patterns and material culture - i…
From Calcium to Cadmium: Testing the Pairing Functional through Charge Radii Measurements of Cd100−130
2018
Differences in mean-square nuclear charge radii of $^{100--130}\mathrm{Cd}$ are extracted from high-resolution collinear laser spectroscopy of the $5s\text{ }{^{2}S}_{1/2}\ensuremath{\rightarrow}5p\text{ }{^{2}P}_{3/2}$ transition of the ion and from the $5s5p\text{ }{^{3}P}_{2}\ensuremath{\rightarrow}5s6s\text{ }{^{3}S}_{1}$ transition in atomic Cd. The radii show a smooth parabolic behavior on top of a linear trend and a regular odd-even staggering across the almost complete $sdgh$ shell. They serve as a first test for a recently established new Fayans functional and show a remarkably good agreement in the trend as well as in the total nuclear charge radius.
