Transport in nanowire-based quantum dot systems: Heating electrons and confining holes
Quantum dots embedded in an electronic circuit allow precise control over the charge transport behaviour of the system: Charge carriers can be individually trapped or precisely shuffled between a series of quantum dots in a strictly sequential manner. This introduces ideal conditions to study fundamental quantum physics and such devices are in the focus of extensive efforts to develop quantum info
Attitudes towards HPV vaccination in Sweden: a survey study
Background: While HPV vaccination uptake in Sweden is quite high, at around 80%, vaccine hesitancy remains an issue in countries throughout Europe. The latter can be related to a contemporary context of increased contestation of expert knowledge and of a large share of information on health-related issues including vaccination today being sought via the internet. Still, there is a paucity of recen
Size-based isolation and detection of renal carcinoma cells from whole blood
Renal cell carcinoma (RCC) is a tumour type with an indolent growth pattern and rather vague symptoms. The present study developed a platform for liquid biopsy of RCC based upon the isolation of circulating tumour cells (CTCs). Founded on the observation that RCC tumour cells are considerably larger than leucocytes, the present study employed a microfluidics-based system for isolation of RCC CTCs
Intersecting Ideologies of Gender and Religion at the Nexus of Consumer Acculturation and Resistance : “SOYBOYS" AND "FAGGOTS" FOR SALE
Conceptualizing the Role of Target-Specific Environmental Transformational Leadership between Corporate Social Responsibility and Pro-Environmental Behaviors of Hospital Employees
The healthcare sector throughout the world is identified for its outsized carbon footprint. Despite the mounting importance of employees’ pro-environmental behavior (PEB) for decarboniza-tion, the role of PEB in a healthcare context was less emphasized previously, especially in a developing country context. To address this knowledge gap, the current work was carried out to examine the relationship
Estimating the Direct Effect between Dietary Macronutrients and Cardiometabolic Disease, Accounting for Mediation by Adiposity and Physical Activity
Assessing the causal effects of individual dietary macronutrients and cardiometabolic disease is challenging owing to the complexity to distinguish direct effects from those mediated or confounded by other factors. To estimate these effects, intake of protein, carbohydrate, sugar, fat, and its subtypes were obtained using food frequency data derived from a Swedish population-based cohort (n~60,000
Some Aspects on Pole-Placement Design
Pole-placement design for SISO systems are discussed in input-output formulation. It is shown how the different design parameters influence the performance of the closed loop system. For instance, the influence of sampling period, anti-aliasing filter, and desired closed loop performance are treated in detail. Rules of thumb for the choice of the different parameters are given.
Analysis of time delays in synchronous and asynchronous control loops
In this paper we describe how to determine the time delays caused by synchronous and asynchronous control loops. These time delays can vary in a quite irregular way and can cause problems for the control loops closed over a communication network of, for instance, field-buses. Different setups allowing an arbitrary number of communication layers are analyzed. The theoretical derivations are illustr
On the reheat furnace control problem
The purpose of this paper is to develop a model and control algorithm for the slab temperature control problem, which is the control of a number of steel blocks (slabs) passing through a furnace burner zone. The slab temperature is controlled by varying the zone temperatrure. First a model for a single slab passing through the furnace is developed and the parameters are estimated. Data from the re
Thickness control for a plate mill
The purpose of this paper is to describe the design of a multivariable control law for a hot plate mill. The design is performed on models adapted to the plate mill at The Danish Steel Work Ltd. The model for the rolling mill is divided into nonlinear models for the hydraulic systems performing the thickness control and a multivariable linear model for the rolling stand. The parameters of the mode
A potential wearable solution for preventing heat strain in workplaces : The cooling effect and the total evaporative resistance of a ventilation jacket
The increase in average seasonal temperatures has an impact in the occupational field, especially for those sectors whose work activities are performed outdoors (agricultural, road and construction sectors). Among the adaptation measures and solutions developed to counteract occupational heat strain, personal cooling garments represent a wearable technology designed to remove heat from the human b
El Niño Southern Oscillation, monsoon anomaly, and childhood diarrheal disease morbidity in Nepal
Climate change is adversely impacting the burden of diarrheal diseases. Despite significant reduction in global prevalence, diarrheal disease remains a leading cause of morbidity and mortality among young children in low- and middle-income countries. Previous studies have shown that diarrheal disease is associated with meteorological conditions but the role of large-scale climate phenomena such as
The history and future of the pandemic present : The role of experience and predictions in Sweden’s management of COVID-19
Our understanding of the present is informed by the past and the future as ideas about where we are right now are shaped by our memories of where we have been and our expectations about where we are going. This paper explores how the understanding of the COVID-19 pandemic was influenced both by experiences from past pandemics and predictions about the present. The paper focuses on the Swedish Publ
Evidence of segmental articulations : Acceleration determines vowel segment duration in Swedish Word Accents
This study addresses a one-to-one relation between articulation and acoustics at segment boundaries. The study focuses on Swedish word accents and how a rising or falling tone affect vowel segment duration. The paper explains how segment boundaries are a result of rapid movements of the articulators. In the acceleration profile, this is identified as peak acceleration, which can be measured. The t
Games of Justice: Ethnographic Inquiries on Space, Subjectivity and Law in Northern Kurdistan
This study presents an ethnographic exploration of subjective experiences relying on different historicizations and the ways they inform the connections between law and justice in Northern Kurdistan. By analyzing law and justice as ethnographic objects whose forms and functions are contingent upon being named and attributed meanings, inquiries focus on various historicizations/spatializations in N
Elucidating the child’s perspective in health promotion: children’s experiences of child-centred health dialogue in Sweden
Promoting young children's health through health promotion activities is an investment for the future. In the Child Health Services in the south of Sweden a structured Child-Centred Health Dialogue (CCHD) directed to all 4-year-old children was developed using illustrations based on the most important health messages associated with the promotion of healthy lifestyle in preschool children. The aim
Biofilm formation on three different endotracheal tubes : a prospective clinical trial
BACKGROUND: Biofilm formation on endotracheal tubes (ETTs) is an early and frequent event in mechanically ventilated patients. The biofilm is believed to act as a reservoir for infecting microorganisms and thereby contribute to development and relapses of ventilator-associated pneumonia (VAP). Once a biofilm has formed on an ETT surface, it is difficult to eradicate. This clinical study aimed to c
Pregnancy-induced Cardiovascular Pathologies : Importance of Structural Components and Lipids
Pregnancy leads to adaptations for maternal and fetal energy needs. The cardiovascular system bears the brunt of the adaptations as the heart and vessels enable nutrient supply to maternal organs facilitated by the placenta to the fetus. The components of the cardiovascular system are critical in the balance between maternal homeostatic and fetus driven homeorhetic regulation. Since lipids interse
Patterns in hospital readmissions after ischaemic stroke – An observational study from the Swedish stroke register (Riksstroke)
Introduction: While acute treatment and secondary prevention in stroke have undergone major improvements, hospital readmission after index stroke remains high. However, there are few reports on long-term readmission patterns. Patients and methods: For this prospective observational study, data on demographics, functional status and living conditions were obtained from the Swedish Stroke Register (
