This research has been conducted to measure the brake particle emission from freight trains drag braking operation. It only focuses on mechanical brakes by using two different brake pad material one is sintered, and another one is composite, in combination with grey cast iron brake disc. All the materials have been collected from real time braking operations from Green cargo. This research is an e
This study investigated the influence of various native and modified starches on the quality and staling behaviour of gluten-free bread. Four starch types: native wheat starch, cross-linked tapioca starch, fractionated native potato starch (FPS), and acetylated potato starch (Amylacetate) were evaluated by incorporating them into a standardized gluten-free bread formulation as the main starch sour
This thesis is a comparative analysis of five cases, in which criminal responsibility and mental disorder were in issue. Andrea Yates drowned her five children. John W. Hinckley Jr shot and injured President Ronald Reagan. Kjeldsen raped and assassinated a taxi driver on his way from Calgary to Banff. Mijailo Mijailovic attacked and killed the Swedish minister of foreign affairs Anna Lindh. Sara S
Since the earliest economic historical studies wage series have been used to sketch economic development both at the macro and the household level. This dissertation takes advantage of new data from women and men, working in both the countryside and in towns, as well as employed both by the day and on long-term contracts, in order to make an in-depth quantitative look at the relationships between
In today’s competitive vehicle industry, fuel efficiency and weight plays a crucial role in performance and to maintain an attractive market position. The increasing technological development is opening new possibilities to design components with lighter materials. All components on Scania buses are favorably designed with as low weight as possible since the measured load on the back axis determin
F-18-flutemetamol is a positron emission tomography (PET) tracer for in vivo amyloid imaging. The ability to classify amyloid scans in a binary manner as 'normal' versus 'Alzheimer-like', is of high clinical relevance. We evaluated whether a supervised machine learning technique, support vector machines (SVM), can replicate the assignments made by visual readers blind to the clinical diagnosis, wh
Astrocytes appear to be important mediators in the clearance of amyloid beta1-42 (A beta), the key component of senile plaques characteristic of Alzheimer's disease (AD). Recently, we found the amyloid associated proteins (AAPs) alpha 1-antichymotrypsin (ACT), apolipoprotein J and E (ApoJ and ApoE) and a mixture of serum amyloid P (SAP) and C1q (SAP-C1q) to modify A beta-uptake by human astrocytes
The Child Feeding Questionnaire (CFQ) assesses parental feeding attitudes, beliefs and practices concerned with child feeding and obesity proneness. While the questionnaire has been developed and primarily used in the U.S., validation studies in other countries are limited. The aim of this study was to examine the psychometric properties of the CFQ among mothers with preschoolers in Sweden and the
Impact cratering is today recognized as a fundamental geological process on all rocky bodies in the solar system. On Earth, however, processes such as plate tectonics and erosion have eradicated most craters from the geological record, or they may be buried under sediments, oceans, and vegetation. The formation of a hypervelocity impact crater involves extreme pressures and temperatures that induc
Popular Abstract in SwedishEn av de viktigaste forskningsfrågorna inom matematikutbildning handlar om förståelse. Det huvudsakliga syftet med den här avhandlingen har varit att nå insikt i olika förståelseformer i skolmatematik och former av lärandeidentiteter i två lärandemiljöer. Avhandlingens specifika fokus var flexibla sätt att urskilja delar och avgränsa helheter och undersöka hur lärande inA central question in mathematics education research concerns understanding. The main objective of the present thesis has been to obtain insights into flexible modes of knowing in school mathematics in two school class contexts, and how these relate to modes of being a learner in these contexts, with specific focus on learners’ flexible ways of discerning parts and delimiting wholes, and how they
Hemiparasitic plants accumulate nutrients in their leaves and therefore produce high-quality litter with faster decomposition and nutrient release rates compared to non-parasitic litter. Higher levels of plant-available nitrogen (N) in the presence of hemiparasitic plants have been attributed to this 'litter effect', but effects on N dynamics in the soil remain unstudied. We tested the hypothesis
Sensitive and frequent digital remote memory assessments via mobile devices hold the promise to facilitate the detection of cognitive impairment and decline. However, in order to be successful at scale, cognitive tests need to be applicable in unsupervised settings and confounding factors need to be understood. This study explored the feasibility of completely unsupervised digital cognitive assess
AimsWe recently identified a metabolic signature of three amino acids (tyrosine, phenylalanine, and isoleucine) that strongly predicts diabetes development. As novel modifiable targets for intervention are needed to meet the expected increase of cardiovascular disease (CVD) caused by the diabetes epidemic, we investigated whether this diabetes-predictive amino acid score (DM-AA score) predicts dev

Popular Abstract in Swedish Hur kommer det sig att liknande reformprogram återfinns i olika länder? Varför väljs vissa idéer framför andra? Avhandlingen syftar till att öka förståelsen av så kallad policydiffusion, spridning av olika typer av policy, och den dynamik som omgärdar spridningen. Detta görs genom att undersöka hur externa, eller utländska, idéer integreras och översätts i en ny omgivniSimilar policies may be found in different countries. This, in turn, is an indication that policies travel. But why are certain policies imitated while others are not? The author seeks to further our understanding of policy diffusion and its dynamics by investigating how foreign ideas are integrated and translated into new contexts, and how these imported ideas influence national policymaking and
This thesis presents a study on performance analysis and optimal design of heat exchangers and heat exchanger networks. The study includes an experimental investigation of steam condensation in plate heat exchangers, optimal design of plate heat exchangers and plate-fin heat exchangers, and optimization of heat exchanger networks. In the experimental investigation of steam condensation in plate h
Aims To compare the effect of initial monotherapy with either bisoprolot or enalapril, followed by their combination, on mortality and hospitalization in patients with mild-to-moderate CHF. Methods and results One thousand and ten patients with mild-to-moderate CHF and left ventricular ejection fraction <= 35%, without ACE-inhibitor, beta-blocker, or angiotensin-receptor-blocker therapy were rando
Popular Abstract in Swedish I det här arbetet studerades kontaktallergi för metaller som finns i olika stentar. Patienterna som ingick i studien hade blivit stentade med olika typer av stentar. En av stentarna var gjord av rostfritt stål (nickelstent) och den andra var förgylld (guldstent). Resultaten av lapptestningen visade att patienterna hade en hög frekvens av både guld- och nickelallergi, ocA large number of patients are treated with coronary stents, and restenosis (recurrent narrowing of the vessel) is a serious problem. Contact allergy to metal ions eluted from stainless steel stents has been suggested to contribute to in-stent restenosis. Studies have reported a higher rate of restenosis with gold-plated stents, but the correlation to contact allergy was not evaluated. Nickel is t
CK2 is an extremely pleiotropic Ser/Thr protein kinase, responsible for the generation of a large proportion of the human phosphoproteome and implicated in a wide variety of biological functions. CK2 plays a global role as an anti-apoptotic agent, a property which is believed to partially account for the addiction of many cancer cells to high CK2 levels. To gain information about the CK2 targets w
Background: The Dachshund homolog 2 (DACH2) gene has been implicated in development of the female genital tract in mouse models and premature ovarian failure syndrome, but to date, its expression in human normal and cancerous tissue remains unexplored. Using the Human Protein Atlas as a tool for cancer biomarker discovery, DACH2 protein was found to be differentially expressed in epithelial ovaria
