In this paper, we present the findings of a Universitas 21 (U21) Graduate Research Project collaboration between Pontificia Universidad Católica de Chile, the University of Nottingham, England, and Lund University, Sweden. This project brought together six doctoral candidates at various stages in their postgraduate careers. The students had conducted qualitative and quantitative inquiry into diver

Modification of the surface electronic properties of vertically aligned and randomly distributed carbon nanotubes and the hydrophobic character after exposure to Ar:F2 and CF4 plasma are exploited to optimize the sensing characteristics of these materials. The sensing properties of fluorinated carbon nanotubes are disclosed by probing their stability and responsiveness towards the detection of two

This work demonstrates the sensitivity of lens antenna arrays operating at millimeter-wave (mmWave) frequencies. Considering a Rotman lens array in receive mode, our investigation focuses on its most imperative defect: aberration of electromagnetic (EM) energy. Aberration leads to spillover of electric fields to neighboring ports, reducing the lens' ability to focus the EM energy to a desired port

Background: Loss of the vestibulo-ocular reflex (VOR) affects visual acuity during head movements. Previous studies have shown that compensatory eye-saccades improve visual acuity and that the timing of the saccade is important. Most of the tests involved in testing VOR are made with passive head movement, that do not necessarily reflect the activities of daily living and thus not being proportion

Rapid urbanization and the growth in the number of motorized vehicles has dramatically marginalized cycling in Chinese cities since the end of the 1990s. The deterioration in air quality and the urban environment is severely challenging urban livability and public health. The cities are seeking effective policies to alleviate these problems, and revitalizing bicycle transport has received increasi

Smoking is considered the most important preventable risk factor in relation to the development of complications during pregnancy and delivery. The aim of this study was to evaluate the effectiveness of an intensive 6-week gold standard programme (GSP) on pregnant women in real life.

BackgroundAdolescents’ use of alcohol, cannabis and other psychoactive substances has significantly increased in European countries. Parallel to this web-based screening and brief intervention have been disseminated. An important question is if it is based on evidence for effect? Therefore, the aim of this review is to evaluate the evidence for effect. MethodA systematic literature search was per

Universities around the world have increasingly turned to digital infrastructures as a way to revamp the arts and humanities. This article contributes a fresh understanding by examining the material development of HumlabX, a research laboratory for digital humanities at Umea° University, Sweden. Specifically, we approach the empirical case as a timeline of research funding, projects, events, and d

The main purpose of this study was to investigate whether the outcome obtained at the end of a work rehabilitation programme for people with various disabilities were stable in a one-year perspective. An additional aim was to explore which factors influenced the outcome upon completion of work rehabilitation and at the one-year follow-up. The study used information from a database and comprised 29

To accomplish timing recovery/synthesis in high-speed communication systems, a 24-b numerically controlled oscillator (NCO) IC using a circuit design technique called true single-phase clock (TSPC) pipelined CMOS has been fabricated in a standard 1.2-μm CMOS process. The device achieves a maximum tested input clock rate of 700 MHz, which results in an output frequency tuning range from DC up to 35

The aim of this study was to validate the Edholm scale (Edholm, 1966) and the ISO 8996 standard (International Organization for Standardization [ISO], 1990) by comparing the metabolic rates estimated for both methods with the actual measured metabolic rate (MMeas) in 6 manual material handling tasks simulated under laboratory conditions. The metabolic rate was calculated from oxygen consumption VO

Objective – The role of the academic librarian has become increasingly educative in nature. In this study, the critical friend method was introduced among teaching librarians in an academic setting of medicine and health sciences to ascertain whether this approach could be implemented for feedback on teaching of these librarians as part of their professional development. Methods – We used a singl

The optical spectra of a quantum cascade laser structure under nonequilibrium conditions is studied using the technique of nonequilibrium Green functions. We focus on the impact of Coulomb corrections and their dependence on the operating conditions. The role of the static mean field due to the charge distribution by electrons and ioninzed donors is investigated.

Objective: Compare perioperative course and long-term mortality after liver resection for colorectal cancer (CRC) metastases between patients who had preoperative treatment with portal vein embolization (PVE) and chemotherapy or chemotherapy alone. Methods: Among patients undergoing liver resection for CRC metastases following preoperative chemotherapy treatment, 17 patients who had received pre

Controlled resistive loads can contribute to damping of electro-mechanical oscillations. This paper presents an on-off damping controller for a single machine system. It was used at a field test in Southern Sweden to damp oscillations of a 0.9 MW hydro power generator. The controller used estimated machine frequency as input and controlled a 20 kW resistive load via thyristor switches. The field m
