This thesis is based on the results concerning the epitaxial growth and characterization of silicon (Si) and germanium (Ge) nanostructures. The growth technique was the Ultra High Vacuum Chemical Vapor Deposition (UHV-CVD) that works in relatively low temperatures and low growth pressures. The UHV-CVD chamber was also used for the reduction experiments. The work presented here involves three diff
Disposal behaviour represent the last phase in the consumption cycle. From an environmental point of view it is extremely important to know the factors behind individual behaviour in waste handling. There are several aspects of interest, for example willingness of waste separation and re-use of products. The aim of this article is to analyse the importance of environmental concern, disposal behavi
The concept of “Sustainable water use” (SWU) aims to assure three pillars of sustainability related to the water sector: the social, environmental, and economical. Industrial development, especially in developing countries, requires an adequate response, as industrial activities are recognized as one of the major sources of water pollution, what leads to deterioration of environmental safety and w
The current plastic system is unsustainable and needs to change. Plastics are mainly produced from fossil feedstock, contributing to greenhouse gas emissions, and low rate of post-consumer recycling results in pollution on land and in oceans with high ecological impact, and huge loss of valuable material. There is an urgent need to find solutions for shifting the raw material base to renewable res
Background: Endometriosis and irritable bowel syndrome (IBS) have similar symptoms, pathogenesis, and risk factors. These diagnoses often coexist and are frequently misdiagnosed leading to diagnostic delays. This study of a population-based cohort aimed to investigate associations relating to endometriosis and IBS and to compare gastrointestinal symptoms between endometriosis and IBS. Method: The
Before performing 177Lu-DOTATATE therapy for neuroendocrine tumors, somatostatin receptor (SSTR) PET imaging is currently used to confirm sufficient tumor SSTR expression, but it also has potential to be used to personalize treatment by predicting absorbed doses to critical organs. This study aims to validate the predictive capability of SSTR PET in anticipating renal absorbed dose in the first cy
Evidence from neuropathological cohorts indicates that a CSF α-synuclein (α-syn) seed amplification assay (SAA) might provide quantitative kinetic parameters correlating with α-syn pathology burden in patients with Lewy body disease (LBD). Studies are needed to assess their longitudinal trend during the presymptomatic and clinical disease phases and their correlation with measures of disease progr
Background Pulmonary nodules (PNs) are clinically challenging because differentiation between benign and malignant PNs is not possible at CT detection; recurring CT examinations and invasive procedures are often required in PN follow-up. Purpose To investigate PN prevalence in a middle-aged population and the risk factors associated with these nodules. Materials and Methods In this secondary analy
Cavum septum pellucidum (CSP) is commonly observed upon neuroimaging examination in individuals exposed to repetitive head impacts (RHI) and post-mortem in cases with chronic traumatic encephalopathy. Consequently, CSP has been proposed as a potential biomarker for RHI-related neurodegeneration, yet prevalence estimates of CSP across other neurodegenerative diseases and its clinical implications a
Background: Cataracts are the leading cause of reversible blindness globally, disproportionately affecting populations in low- and middle-income countries. In Ethiopia, cataracts remain a significant public health concern. Despite the effectiveness of cataract surgery in restoring vision, information on recovery time and its predictors remain limited. The aim of this study was to assess time to re
ObjectiveThe study aimed to explore attitudes and beliefs among midwives, obstetricians, and neonatologists regarding umbilical cord clamping practices, including scenarios involving neonatal compromise. The study was conducted in the context of exploring the potential for implementing intact cord resuscitation.Study designA national cross-sectional survey was administered electronically, using an
There is an urgent need for accurate and validated methods to measure plasma phosphorylated tau (p-Tau) biomarkers in Alzheimer’s disease (AD). In this study, we compared the performance of new commercially available plasma p-Tau217 assay developed by ALZpath to other established p-Tau assays in an autopsy-confirmed sample. We included 72 participants from the Arizona Study of Aging and Neurodegen
Although the information obtained from in vivo proton magnetic resonance spectroscopy (1H MRS) presents a complex-valued spectrum, spectral quantification generally employs linear combination model (LCM) fitting using the real spectrum alone. There is currently no known investigation comparing fit results obtained from LCM fitting over the full complex data versus the real data and how these resulAlthough the information obtained from in vivo proton magnetic resonance spectroscopy (1H MRS) presents a complex-valued spectrum, spectral quantification generally employs linear combination model (LCM) fitting using the real spectrum alone.

BACKGROUND AND AIM: In many places worldwide there is an ongoing urbanization, often achieved through densification. An increased number of inhabitants in an area often leads to both increased traffic and placement of new buildings closer to roads, and thus increased population exposure to road traffic noise. The aim of the study was to estimate and compare the health impacts of road traffic noise
Background: In Alzheimer’s disease (AD), the associations between tau pathology and brain atrophy and cognitive decline are well established, but imperfect. We investigate whether cerebrospinal fluid (CSF) biomarkers of biological processes (vascular, synaptic, and axonal integrity, neuroinflammation, neurotrophic factors) explain the disconnection between tau pathology and brain atrophy (brain re
IMPORTANCE: The number of patients prescribed long-term opioids and benzodiazepines and complications from their long-term use have increased. Information regarding the perioperative outcomes of patients prescribed these medications before surgery is limited.OBJECTIVE: To determine whether patients prescribed opioids and/or benzodiazepines within 6 months preoperatively would have greater short- a
Objective: To study the impact of GH dose and age at GH start in girls with Turner syndrome (TS), aiming for normal height and age at pubertal onset (PO) and at adult height (AH). However, age at diagnosis will limit treatment possibilities. Methods: National multicenter investigator-initiated studies (TNR 87-052-01 and TNR 88-072) in girls with TS, age 3–16 years at GH start during year 1987–1998
IntroductionInternet-based interventions are called for within rehabilitation to meet the limited access to support for self-management after stroke. Therefore, a new intervention program, “Strategies for Empowering activities in Everyday life” (SEE) was developed. The aim of this study was to explore and describe how clients with stroke and their occupational therapists experienced the SEE interv
