Parents in adult psychiatric care and their children : a call for mor...
Afzelius, Maria; Östman, Margareta; Rastam, Maria; Priebe, Gisela Journal article in Nordic Journal of Psychiatry;1 : Taylor & Francis (2018)	Journal article

English abstract:

Background: A parental mental illness affects all family members and should warrant a need for support.Aim: To investigate the extent to which psychiatric patients with underage children are the recipients of child-focused interventions and involved in interagency collaboration.Methods: Data were retrieved from a psychiatric services medical record database consisting of data regarding 29,972 individuals in southern Sweden and indicating the patients' main diagnoses, comorbidity, children below the age of 18, and child-focused interventions.Results: Among the patients surveyed, 12.9% had registered underage children. One-fourth of the patients received child-focused interventions from adult psychiatry, and out of these 30.7% were involved in interagency collaboration as compared to 7.7% without child-focused interventions. Overall, collaboration with child and adolescent psychiatric services was low for all main diagnoses. If a patient received child-focused interventions from psychiatric services, the likelihood of being involved in interagency collaboration was five times greater as compared to patients receiving no child-focused intervention when controlled for gender, main diagnosis, and inpatient care.Conclusions: Psychiatric services play a significant role in identifying the need for and initiating child-focused interventions in families with a parental mental illness, and need to develop and support strategies to enhance interagency collaboration with other welfare services.

Intercombination transition rates in N+
Shen, Xiaozhi; Liu, Juan; Sang, Cuicui; Jönsson, Per Journal article in Physical Review A;1 : American Physical Society (2018)	Journal article

English abstract:

Accurate intercombination transition rates (A), arising from the 2s(2)2pnl (n = 3, 4, 5; l = s, p, d) and 2s2p(3) configurations of N+, are reported. Wavefunctions for the studied states in N+ are determined using the multiconfiguration Dirac-Hartree-Fock (MCDHF) method and account for the effects of valence, corevalence (CV), and core-core (CC) correlations. It is found that the combined CV and CC correlation effects are important for accurate predictions of intercombination rates of N+. A strong spin-orbit mixing between the states P-3(1)o and P-1(1)o of 2s(2)2p3s causes that the intercombination rates on its states P-1,3(1)o are exceedingly sensitive to electron correlations and other corrections. The strong visible intercombination lines of N+ arise from the 2s(2)2p3s-2s(2)2p3p and 2s(2)2p3p-2s(2)2p3d transitions. There are also strong infrared and ultraviolet intercombination lines that have important applications in plasma diagnosis of radiative cooling coefficient and abundance. Different systematic methods are used to evaluate the intercombination rates and their uncertainties. For relatively strong lines (gf > 0.01) of 2s(2)2p3l(l = s, p, d), 2s(2)2p4l(l = s, p, d) and 2s(2)2p5s the uncertainties are separately estimated to be within 7%, 12%, and 20%. The rates of extremely weak lines, gf < 10(-6), are of interests in the temperature and density diagnostic in nebulae, but are remarkably difficult to accurately calculate. The present calculations have included appropriate electron correlations to deal with them and provide guidance for further studies.

Chen, Zhan-Bin; Guo, Xue-Ling; Wang, Kai Journal article in Journal of Quantitative Spectroscopy and Radiative Transfer; : Elsevier (2018)	Journal article

English abstract:

An extensive set of level energies, wavelengths, line strengths, oscillator strengths, lifetimes, hyperfine structures, Lande g(J)-factors, electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2), and magnetic quadrupole (M2) radiative transition rates among the lowest 318 states arising from the 2s(2)2p(4), 2s2(p)5, 2p(6), 2s(2)2p(3)3l (l = 0, 1, 2), 2s2p(4)31 (l = 0, 1, 2), 2p(5)3l (l = 0, 1, 2), and 2s(2)2p(3)4l (l = 0, 1, 2, 3) configurations has been obtained for Se XXVII. These new data, calculated within the frameworks of the multi-configuration Dirac-Hartree-Fock method and the second-order many-body perturbation theory, fill in the gap existing in the atomic data needed for the diagnostic processes of tokamak plasmas. Using two methods allowed us to make an intercomparison and to estimate the uncertainties on the obtained data. The results arising in the two sets of calculations are quite close, suggesting that there is a high degree of convergence achieved in our work. i.e., our two sets of energies agree to better than 0.02%, and the lifetimes mostly agree to within 2%. Comparison is also made with the limited number of experimental data and previous computations to assess the accuracy of our calculations. (C) 2017 Elsevier Ltd. All rights reserved.

Wu, Runrun; Ma, Yue; Pan, Jianming; Lee, Shih-Hui; Liu, Jinxin; Zhu, Hengjia; Gu, Runxin; Shea, Kenneth J.; Pan, Guoqing Journal article in Biosensors and Bioelectronics; : Elsevier (2018)	Journal article

English abstract:

In this work, we demonstrated a nano-decorated porous impedance electrode sensor for efficient capture, rapid killing and ultrasensitive detection of bacteria. The multi-functional sensor was prepared by a facile sono-chemical method via in situ deposition of antibacterial prickly Zn-CuO nanoparticles and graphene oxide (GO) nanosheets on a Ni porous electrode. Due to the surface burr-like nanostructures, the nano-decorated impedance sensor exhibited very good bacterial-capture efficiency (70 - 80% in 20 min) even at a low concentration of 50 CFU mL(-1), rapid antibacterial rate (100% killing in 30 min) and high detection sensitivity (as low as 10 CFU mL(-1)). More importantly, the nano-decorated sensor has proven to be highly effective in quantitative detection of bacteria in a biological sample, for example, a rat blood sample spiked with E. coll. Despite the complexity of blood, the sensor still exhibited excellent detection precision within 30 min at bacteria concentrations ranging from 10 - 10(5) CFU mL(-1). The simplicity, rapidity, sensitivity, practicability and multifunctionality of this impedance sensor would greatly facilitate applications in portable medical devices for on-the-spot diagnosis and even the possibility for simultaneous therapy of diseases caused by bacterial infections.

Rechargeable, flexible and mediator-free biosupercapacitor based on t...
Bobrowski, Tim; Arribas, Elena Gonzalez; Ludwig, Roland; Toscano, Miguel D.; Shleev, Sergey; Schuhmann, Wolfgang Journal article in Biosensors and Bioelectronics; : Elsevier (2018)	Journal article

English abstract:

We present a transparent and flexible self-charging biosupercapacitor based on an optimised mediator- and membrane-free enzymatic glucose/oxygen biofuel cell. Indium tin oxide (ITO) nanoparticles were spray-coated on transparent conducting ITO supports resulting in a flocculent, porous and nanostructured electrode surface. By this, high capacitive currents caused by an increased electrochemical double layer as well as enhanced catalytic currents due to a higher number of immobilised enzyme molecules were obtained. After a chemical pretreatment with a silane derivative, bilirubin oxidase from Myrothecium verrucaria was immobilized onto the ITO nanostructured electrode surface under formation of a biocathode, while bioanodes were obtained by either immobilisation of cellobiose dehydrogenase from Corynascus thermophilus or soluble PQQ-dependent glucose dehydrogenase from Acinetobacter calcoaceticus. The latter showed a lower apparent K-M value for glucose conversion and higher catalytic currents at mu M glucose concentrations. Applying the optimised device as a biosupercapacitor in a discontinuous charge/discharge mode led to a generated power output of 0.030 mW/cm(2) at 50 mu M glucose, simulating the glucose concentration in human tears. This represents an enhancement by a factor of 350 compared to the power density obtained from the continuously operating biofuel cell with a maximum power output of 0.086 mu W/cm(2) under the same conditions. After 17 h of charging/discharging cycles a remarkable current enhancement was still measured. The entire device was transferred to flexible materials and applied for powering a flexible display showing its potential applicability as an intermittent power source in smart contact lenses.
