CuInSe2 Quantum Dots Hybrid Hole Transfer Layer for Halide Perovskite Photodetectors

A novel hybrid hole transport layer (HTL) of CuInSe2 quantum dots (QDs)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) was developed to enhance the performance of halide metal perovskite (MAPbI3)-based photodetectors. The introduction of CuInSe2 QDs not only improved the wettability of the PEDOT:PSS HTL for the growth of perovskite crystals but also facilitated the transportat

Mechanism and rate constants of the CH2 + CH2CO reactions in triplet and singlet states : A theoretical study

Ab initio and density functional CCSD(T)-F12/cc-pVQZ-f12//B2PLYPD3/6-311G** calculations have been performed to unravel the reaction mechanism of triplet and singlet methylene CH2 with ketene CH2CO. The computed potential energy diagrams and molecular properties have been then utilized in Rice–Ramsperger–Kassel–Marcus-Master Equation (RRKM-ME) calculations of the reaction rate constants and produc

Regional differences in coronary revascularization procedures and outcomes : a nationwide 11-year observational study

Aims: The study investigated whether regional differences in choice of coronary revascularization affected outcomes in Sweden.Methods and results: We conducted a prospective nationwide study of outcome in patients undergoing coronary artery bypass grafting (CABG, n = 47 065) or percutaneous coronary intervention (PCI, n = 140 945) from 2001 through 2011, tracked for a median of 5 years. During thi

Highly Sensitive Membraneless Fructose Biosensor Based on Fructose Dehydrogenase Immobilized onto Aryl Thiol Modified Highly Porous Gold Electrode : Characterization and Application in Food Samples

In this paper we present a new method to electrodeposit highly porous gold (h-PG) onto a polycrystalline solid gold electrode without any template. The electrodeposition is carried out by first cycling the electrode potential between +0.8 and 0 V in 10 mM HAuCl4 with 2.5 M NH4Cl and then applying a negative potential for the production of hydrogen bubbles at the electrode surface. After that the m

Sentinel lymph node biopsy in patients with thin melanomas : Frequency and predictors of metastasis based on analysis of two large international cohorts

Background: Sentinel lymph node (SLN) metastasis in patients with thin melanomas (≤1 mm) is uncommon but adverse prognostic factors may indicate an increased risk. We sought to determine how often SLN biopsy (SLNB) was performed in patients with thin melanomas, establish the frequency of SLN metastasis and evaluate the predictive value of ulceration, tumor mitotic rate, and thickness for SLN invol

Long-term Drivers of Taxation in Francophone West Africa 1893–2010

Which factors have driven fiscal revenue in Sub-Saharan Africa in the long run? We address this question by studying quantitatively the long-term relationship between fiscal outcomes, economic expansion and external dependency in four francophone West African countries – Benin, Côte d’Ivoire, Niger and Senegal – between 1893 and 2010. Using panel co-integration modelling we find a long-term relati

Model-based analysis and optimization of a full-scale industrial high-rate anaerobic bioreactor

The objective of this paper is to present the model-based optimization results of an anaerobic granular sludge internal circulation reactor. The International Water Association Anaerobic Digestion Model No. 1 extended with phosphorus (P), sulfur (S), and ethanol is used to describe the main biological and physico-chemical processes. The high-rate conditions within the reactor are simulated using a

Nanny families : Practices of care by nannies, au pairs, parents and children in Sweden

Paying privately for childcare is a growing phenomenon, and its rise in Sweden is particularly interesting because of the vast prevalence there of publicly funded day care. This book combines family practice and childhood studies theory with the personal perspectives of nannies and au pairs, parents, and the children themselves, to provide new understandings of what constitutes ‘good care’.

Nanny care in Sweden : Inequalities of everyday doings of care

A new actor has been (re)introduced into family practices in Sweden: the nanny. Previous ways of organizing care for children (mainly through publicly funded daycare) are today being complemented by a growing private market for childcare, often performed by migrant women. In our research project Care for children in an era of private market service we study the practice of doing care and family in

An Integrative Analysis of Transcriptome and Epigenome Features of ASCL1–Positive Lung Adenocarcinomas

Introduction: A subgroup of lung adenocarcinoma shows neuroendocrine differentiation and expression of achaete-scute family bHLH transcription factor 1 (ASCL1), common to high-grade neuroendocrine tumors, small-cell lung cancer and large cell neuroendocrine carcinoma. Methods: The aim of this study was to characterize clinical and molecular features of ASCL1-positive lung adenocarcinoma by using r

Development of Divorce in Sweden 1910-2000: A county-level analysis of divorce and economic determinants

One of the larger changes in society that affected individual’s lives during the 20th century is the increase in divorce rates that happened in almost all industrialized countries. It went from being an uncommon feature reserved for the rich to a prominent part of family-life. The increase occurred against the backdrop of economic growth and the industrialization. This study constructs a data set

Will a water gradient in oral mucosa affect transbuccal drug absorption?

Formulations for buccal drug delivery often comprise polymers to facilitate mucoadhesion based on water sorption. The main objective of the current study was therefore to evaluate the effect of dehydration on drug uptake through oral mucosa. We have used diffusion cells with excised porcine mucosa to study uptake of three alternative drugs (i.e., Metronidazole, Benzydamine and Xylometazoline) toge

Dietary intervention with an Okinawan-based Nordic diet in type 2 diabetes renders decreased interleukin-18 concentrations and increased neurofilament light concentrations in plasma

Food may induce inflammation and favor development of metabolic diseases, which have been associated with increased inflammation and potential risk of cognitive impairment. It is customary to know whether food or disease promote inflammation. Our hypothesis was that Okinawan-based Nordic (O-BN) diet leads to decreased circulating concentrations of inflammatory and neural biomarkers. The objectives

Structure of low-lying states in 128Ba from γ-γ angular correlations and polarization measurements

A study of the low-lying levels of 128Ba was performed using three clover detectors in a compact arrangement. The levels were populated by beta decay of 128La which was produced by the fusion evaporation reaction 116Sn(16O, 1p3n). γ-γ angular correlations and polarization measurements were performed. The decay properties of several low-lying states were investigated. Spin assignments were made for

Investigation on a high-stratified direct injection spark ignition (DISI) engine fueled with methanol under a high compression ratio

This paper reports an investigation of a highly stratified methanol direct injection spark ignition (DISI) engine with a high compression ratio. The effects of the start of injection (SOI), spray-included angle, injection pressure, and spark timing (ST) on in-cylinder flow, fuel distribution, flame propagation, and engine performance are evaluated in detail. The combustion process of methanol DISI
