Characteristics of adolescents with poor mental health after bariatric surgery

BACKGROUND: About 20% of adolescents experience substantial mental health problems after bariatric surgery.OBJECTIVES: The aim of this study was to explore differences between adolescents with poor mental health (PMH) 2 years after surgery and those with average/good mental health.SETTING: Three university hospitals in Sweden.METHODS: Mental health and health-related quality of life were assessed

Growth of High Material Quality Group III-Antimonide Semiconductor Nanowires by a Naturally Cooling Process

We report on a simple but powerful approach to grow high material quality InSb and GaSb nanowires in a commonly used tube furnace setup. The approach employs a process of stable heating at a high temperature and then cooling down naturally to room temperature with the nanowire growth occurred effectively during the naturally cooling step. As-grown nanowires are analyzed using a scanning electron m

Predictive and prognostic clinical variables in cancer patients treated with adenoviral oncolytic immunotherapy

The development of oncolytic viruses has recently made great progress towards being available to cancer patients. With the breakthrough into clinics, it is crucial to analyze the existing clinical experience and use it as a basis for treatment improvements. Here we report clinical data from 290 patients treated with oncolytic adenovirus. Using clinical variables and treatment characteristics, we c

Crystal Structures in GaAs Nanowires: Growth and Characterization

With their nanometer size cross-section and high aspect ratio, semiconducting nanowires have properties that make them promising as building blocks in future electronic and optoelectronic devices. Because of their small size, their optical and electrical properties can differ from their bulk counterparts, and their geometry allows for material combinations not accessible in thin films. Moreover, n

Evaluating automated support for requirements similarity analysis in market-driven development

In market-driven software development, there is a considerable risk for congestion in the requirements engineering process, as the demand of short time-to-market is combined with a rapid arrival of new requirements from many different sources. Automated analysis of the continuous flow of incoming requirements provides an opportunity to increase the efficiency of the requirements engineering proces

Smog Chamber Experiments of SOA Formation from Gasoline Exhaust and Light Aromatics

Experiments where gasoline exhaust was exposed to UV-radiation to examine Secondary Organic Aerosol (SOA) formation were performed in a smog chamber. The Aerosol Mass Yield (formed SOA/reacted precursor mass) was determined and compared with the yield from a pure precursor experiment in the chamber and from results reported in literature. Preliminary results show that the majority of the organic a

Growth of Semiconductor Nanowires for Solar Cell Applications

Nanowires have the ability to absorb light much more efficient than conventional thin film layers. This makes them candidates for the development of new types of solar cells that have higher efficiency and lower material usage than current technologies. In this thesis fabrication of nanowires with techniques suitable for large area applications are investigated. The nanowires are grown by either M

Charge Transport in Semiconductor Nanowire Quantum Devices: From Single Quantum Dots to Topological Superconductors

This thesis focuses on charge transport in semiconductor InSb nanowire quantum devices, including the electron transport, the hole transport, and the Cooper pair transport. Devices in which InSb semiconductor nanowire quantum dots are coupled with normal metals, superconductors or the proximity effect induced topological superconductors are fabricated and measured. Firstly, we have fabricated and

Interface composition of atomic layer deposited HfO2 and Al2O3 thin films on InAs studied by X-ray photoemission spectroscopy

We present a synchrotron-based XPS investigation on the interface between InAs and Al2O3 or HfO2 layers, deposited by ALD at different temperatures, for InAs substrates with different surface orientations as well as for InAs nanowires. We reveal the composition of the native Oxide and how the high-k layer deposition reduces Oxide components. We demonstrate some of the advantages in using synchrotr
