Many Swedish multifamily buildings from the 1960s are now reaching a stage where major renovation is needed to improve energy performance, indoor environmental quality, and long-term climate performance. At the same time, renovation strategies may involve trade-offs between operational energy savings, embodied carbon, thermal comfort, and material circularity. This thesis evaluates energy-efficien
A total of 24 UAV flights in the vicinity of integrated sensing and communications-enabled (ISAC) antenna systems, called base stations, were selected to investigate whether tracking can be improved using machine learning methods. This was done by inputting time series of range-Doppler (r-D) maps created from continuously calculating channel estimates of the bistatic environment around base statio
Adaptation is essential in maintaining stability during balance-challenging situations. We studied, ill standing subjects with eyes open and closed, adaptive responses of the anteroposterior head, shoulder, hip and knee movements: gastrocnemius and tibialis anterior EMG activity and anteroposterior body Posture when proprioceptive information from the neck or calf muscles underwent vibratory pertu
This paper presents a novel method for the analysis of heart rate variability (HRV) during exercise stress testing enhanced with respiratory information. The instantaneous frequency and power of the low frequency (LF) and high frequency (HF) bands of the HRV are estimated by parametric decomposition of the instantaneous autocorrelation function (ACF) as a sum of damped sinusoids. The instantaneous
OBJECTIVE: To determine moment arm lengths from seven knee muscles and the patellar tendon. The knee muscles were the biceps femoris, semitendinosus, semimembranosus, gracilis, sartorius, and the lateral and medial gastrocnemius muscles. DESIGN: The moment arms were calculated based on MRI measurements. BACKGROUND: Moment arm lengths of different muscles with respect to the joint centre of rotatio
Popular Abstract in Swedish I alla flercelliga organismer behövs utbyte av information mellan cellerna, som bygger upp kroppen. För detta ändamål är cellerna försedda med små antenner, som kan ta emot signaler och kallas därför receptorer. Receptorer kan vara uppbyggda på olika sätt. De flesta receptorer slingrar sig sju gånger genom membranet och har ett gemensamt sätt att fortleda signaler till Seven-transmembrane, G-protein coupled receptors play a central role in physiology since they facilitate cell communication in multicellular organisms by recognition of a broad range of ligands. They also represent important drug targets. Unfortunately, for many of these receptors the endogenous ligands, and, hence, their physiological functions, remain to be identified. These receptors are usuall
OBJECTIVE: To investigate socioeconomic differences in intermittent and daily smoking, and to assess the association between social participation and these two smoking behaviours.DESIGN/SETTING/PARTICIPANTS/MEASUREMENTS: A population of 11 837 individuals interviewed in 1992-94, aged 45-64 years, was investigated in this cross sectional study. A multivariate logistic regression model was used to a
Weak alignment of requirements engineering (RE) with verification and validation (VV) may lead to problems in delivering the required products in time with the right quality. For example, weak communication of requirements changes to testers may result in lack of verification of new requirements and incorrect verification of old invalid requirements, leading to software quality problems, wasted ef
No consensus treatment regime exists beyond surgery for malignant peripheral nerve sheath tumours (MPNST), and the purpose of the present study was to find new approaches to stratify patients with good and poor prognosis and to better guide therapeutic intervention for this aggressive soft tissue cancer. From a total of 67 MPNSTs from Scandinavian patients with and without neurofibromatosis type 1
PURPOSE: To evaluate patients' vision-related activity limitation before and after bilateral cataract surgery using the German version of the Catquest-9SF questionnaire. SETTING: Hanusch Hospital, Vienna, Austria, and Ophthalmic Clinic, Minden, Germany. DESIGN: Questionnaire development. METHODS: This prospective 2-center study included patients who were scheduled for bilateral cataract surgery an
Objective: To study whether transient hyperglycemia adversely affects cerebral energy metabolism in patients with severe traumatic brain lesions. Design and setting: Prospective, nonrandomized study in the neurosurgical intensive care unit of a university hospital. Patients: 108 patients treated for severe traumatic brain lesions. Interventions: All patients were treated according to neurosurgical
Background Pain at the site of intravenous injection of propofol is a common clinical finding. This double-blind, randomized cross-over study was designed to evaluate whether venous occlusion applied during injection of a low dose of propofol reduces the intensity of pain at the site of injection compared with no occlusion. Methods Bilateral 0.5-ml injections of an emulsion containing 10 mg/ml of
OBJECTIVE: To determine the prevalence of orthostatic hypotension (OH), low blood pressure and dizziness, falls and fractures in patients with organic dementia. DESIGN: We prospectively studied 151 patients, assessing the prevalence of OH, hypertension, heart disorders, diabetes mellitus and the use of medication possibly associated with OH. SETTING: The patients were admitted to our psychogeriatr
Objective: To evaluate how often low 5-min Apgar scores (AS(5-min)) at term are associated with asphyxia. Study design: A cohort- and case-control study, including all 183 term infants with AS(5-min) below 7 born at Lund University Hospital during 1993-2002, antepartum deaths excluded. The control group included 183 randomly selected term newborns with AS(5-min) 9-10. Cardiotocography (CTG) traces
The key reaction of protein synthesis, peptidyl transfer, is catalysed in all living organisms by the ribosome - an advanced and highly efficient molecular machine. During the last decade extensive X-ray crystallographic and NMR studies of the three-dimensional structure of ribosomal proteins, ribosomal RNA components and their complexes with ribosomal proteins, and of several translation factors
The Transition Radiation Tracker (TRT) sits at the outermost part of the ATLAS Inner Detector, encasing the Pixel Detector and the Semi-Conductor Tracker (SCT). The TRT combines charged particle track reconstruction with electron identification capability. This is achieved by layers of xenonfilled straw tubes with periodic radiator foils or fibers providing TR photon emission. The design and choic
BACKGROUND: The interpretation of clinical trials and efforts directed at reducing the worldwide burden of coronary disease must take regional differences into account. This study examined the regional differences in baseline characteristics, treatment, and outcome in patients presenting with ST elevation myocardial infarction (STEMI) who were entered into the Magnesium in Coronaries (MAGIC) trial
Objective. To analyze the experience of a single centre using stent-grafts for treatment of complicated acute aortic type B-dissections (EVR-ABD). Design. Retrospective analysis of prospectively collected data from patients undergoing EVR-ABD between January 1997 and December 2004. Methods. EVR-ABD was performed in 31 patients (20 males, median age 74. years (IQR: 64-79)). Indications for treatmen
BACKGROUND: There are few data on how patients on maintenance treatment of reflux oesophagitis take their medication. This study was designed to investigate the dosing patterns of patients on on-demand treatment and to compare lansoprazole with omeprazole in this regard. METHODS: Patients with reflux oesophagitis, initially treated until absence of symptoms, took capsules of either lansoprazole (3
