Predictors of Psychiatric Hospitalization in Ex-Prisoners With Substance Use Problems: A Data-Linkage Study

This study analyzed predictors of psychiatric hospitalization in ex-prisoners with substance use problems (N = 4,081) assessed with the Addiction Severity Index and followed post-release for hospitalizations with psychiatric diagnoses (including suicide attempts). Thirty-four percent were hospitalized, and in Cox regression, several substance-related variables predicted hospitalization, including

Local structure of photoexcited bimetallic complexes refined by quantitative XANES analysis

Photoexcited states of a pyrazolate bridged PtPt dimer and a supramolecular RuCo complex with bipyridine-type ligands were studied using the pump-and-probe X-ray absorption spectroscopy method. The local structure refinement based on the fitting of XANES difference spectra has been performed. The theoretical analysis included the full multiple scattering calculations and the multidimensional inter

Smoking- and alcohol habits in relation to the clinical picture of women with microscopic colitis compared to controls.

Microscopic colitis (MC) induces gastrointestinal symptoms, which are partly overlapping with irritable bowel syndrome (IBS), predominately in middle-aged and elderly women. The etiology is unknown, but association with smoking has been found. The aim of this study was to examine whether the increased risk for smokers to develop MC is a true association, or rather the result of confounding factors

OBJECTIVES: To investigate the association between marital status and lack of internal health locus of control (HLC), taking economic stress and trust into account. STUDY DESIGN: Cross-sectional study. METHODS: The public health survey Skåne 2008 is a postal questionnaire study (55% participation rate). A random sample was invited to participate, and 28,198 individuals aged 18-80 years agre

Sleep quality, use of hypnotics and sleeping habits in different age-groups among older people

Background: Sleep disturbances are common among older people (>65 years). Further, long-term use of sedative-hypnotics in older people is associated with morbidity and mortality. However, older people represent a large span of life years, and few studies have included the oldest-old above 85 years. Aim: To investigate and compare sleep quality, use of hypnotics and sleeping habits in different age

Thermally Activated Exciton Dissociation and Recombination Control the Carrier Dynamics in Organometal Halide Perovskite

Solar cells based on organometal halide perovskites have seen rapidly increasing efficiencies, now exceeding 15%. Despite this progress, there is still limited knowledge on the fundamental photophysics. Here we use microwave photoconductance and photoluminescence measurements to investigate the temperature dependence of the carrier generation, mobility, and recombination in (CH3NH3)PbI3. At temper

Towards single Ce ion detection in a bulk crystal for the development of a single-ion qubit readout scheme

Popular Abstract in English At the beginning of 20th century, scientists started to realize that atoms exhibited the discrete behaviour, e.g. the energies of bond electrons were not continuously distributed, but had discrete values. Light is also transmitted as discrete packages (called photons). These phenomena can not be explained by classical physics, which has been accepted as the law of descrThe work presented in this thesis was concerned with investigating the relevant spectroscopic properties of Ce ions randomly doped in an Y2SiO5 crystal at low temperatures (around 4 K), in order to develop a technique and an experimental set-up to detect the fluorescence photons emitted by a single Ce ion. The aim of the work was to determine whether a single Ce ion (referred to as the readout ion

The effect of a biphasic injectable bone substitute on the interface strength in a rabbit knee prosthesis model.

In joint prosthetic surgery, various methods are used to provide implant stability. We used an injectable bone substitute, composed of calcium sulfate/hydroxyapatite, as bone defect filler to stabilize a tibia prosthesis in an experimental rabbit model. The aim of the study was to investigate and compare the stability of prosthetic fixation with and without the use of an injectable bone substitute

Sandwiched confinement of quantum dots in graphene matrix for efficient electron transfer and photocurrent production.

Quantum dots (QDs) and graphene are both promising materials for the development of new-generation optoelectronic devices. Towards this end, synergic assembly of these two building blocks is a key step but remains a challenge. Here, we show a one-step strategy for organizing QDs in a graphene matrix via interfacial self-assembly, leading to the formation of sandwiched hybrid QD-graphene nanofilms.

Balancing Electron Transfer and Surface Passivation in Gradient CdSe/ZnS Core-Shell Quantum Dots Attached to ZnO

Core-shell (CS) quantum dots (QDs) are promising light absorbers for solar cell applications mainly because of their enhanced photostability compared with bare QDs. Moreover, the superb photostability can be combined with a low number of defects by using CSQDs with a gradient composition change from the core to the shell. Here, we study electron injection from the gradient CSQDs to ZnO nanoparticl

Climate Change, Adaptation, and Formal Education: the Role of Schooling for Increasing Societies' Adaptive Capacities in El Salvador and Brazil

With a worldwide increase in disasters, the effects of climate change are already being felt, and it is the urban poor in developing countries who are most at risk. There is an urgent need to better understand the factors that determine people's capacity to cope with and adapt to adverse climate conditions. This paper examines the influence of formal education in determining the adaptive capacity

Bulk-like transverse electron mobility in an array of heavily n-doped InP nanowires probed by terahertz spectroscopy

Terahertz spectroscopy is employed for the noncontact measurement of transversal mobility in InP nanowires, wherein photonic effects (waveguiding of excitation beam and propagation of terahertz beam in a complex gradient environment) were successfully deconvoluted. Monte Carlo calculations accounting for electron localization and heavy doping were used to determine electron momentum relaxation tim
