Hosting a cultural history of 8.000 years in China, jade has seen a revival in China’s current era. Jadeite is the most expensive type of jade, and the vast majority of jadeite is mined in Myanmar’s Kachin State and sold in China.Spectral Jade is a study of trade, carving, and use of jadeite. The dissertation is based on ethnographic research in different nodes of the jadeite commodity chain, incl

We sampled ammonium sulfate particles and indoor particles of outdoor origin through a small chamber covered with polyvinyl chloride (PVC) flooring. We measured the uptake of semi-volatile organic compounds (SVOC) by the airborne particles in real time. The particles acquired SVOC mass fractions up to 10%. The phthalate ester DEHP (di(2-ethylhexyl)phthalate), a known endocrine disruptor, contribut

In the ActivAbles and STARR projects we have developed interactive training tools for stroke survivors. A prototype system includes an interactive balance foam pad, feedback lamps and a step counting game app which all connect to a central server. The feedback is designed to be inclusive - designs are multimodal, and the setup is flexible and can easily be adapted. We describe the system and repor

Stroke outcome is determined by a complex interplay, where age and stroke severity are predominant predictors. Studies on hemorrhagic stroke indicate that APOE genotype is a predictor of poststroke outcomes,1,2 but results from studies on ischemic stroke are more conflicting.1,3 There is 1 study suggesting an influence of APOE genotype on age at ischemic stroke onset,4 and sex-specific effects on

Background: Traumatic brain injuries continue to be a significant cause of mortality and morbidity worldwide. Most traumatic brain injuries are classified as mild, with a low but not negligible risk of intracranial hemorrhage. To help physicians decide which patients might benefit from a computerized tomography (CT) of the head to rule out intracranial hemorrhage, several clinical decision rules h

Background: Standardized, research-based strategies to guide the implementation and evaluate the effects of housing adaptations (HA) on client outcomes are rare. We hypothesized that, compared to ordinary practice, a standardized assessment and evaluation protocol for HA implementation would better maintain or improve client outcomes over 1 year. Method: Using a cluster design, South Swedish munic

Background: The longevity for people with intellectual disability (ID) has significantly increased in developed countries during the past decades. Consequently, the incidence of cancer is expected to increase in this group. The aim of the present study was to investigate the prescription of pain medication in older cancer patients with intellectual disability (ID) compared to older patients in the

Background: Stability is one of the most fundamental intrinsic characteristics of proteins and can be determined with various methods. Characterization of protein properties does not keep pace with increase in new sequence data and therefore even basic properties are not known for far majority of identified proteins. There have been some attempts to develop predictors for protein stabilities; howe

Background: Brief screening instruments focusing on autism spectrum disorder (ASD) that can be administered in primary care are scarce; there is a need for shorter and more precise instruments. The Autism-Tics, AD/HD and other Comorbidities inventory (A-TAC) has previously been validated for ASD reporting excellent validity. This study aims to determine the psychometric properties of each item in

Background: Meniscus injury and meniscectomy both entail increased risk of knee osteoarthritis (OA). Thigh muscle weakness is a suggested mediator of OA but there is little evidence of its importance for knee OA development after meniscectomy. This study aimed to examine the association between thigh muscle strength after partial meniscectomy in middle-aged subjects with a non-traumatic meniscal t

Introduction Fever is an integral part of the inflammatory response and has therefore likely a physiological role in fighting infections. Nevertheless, whether fever in itself is beneficial or harmful in adults is unknown. This protocol for a systematic review aims at identifying the beneficial and harmful effects of fever control interventions in adults. Methods and analysis This protocol for a s

Avhandlingsarbetet studerar hur turbulent flödesstruktur sammverkar med förbränning av högoktaniga bränslen i partiellt förblandade förhållanden genom numeriska tredimensionella flödessimuleringar. Förbränningsmoder och antändningsprocesser studeras för två olika typfall där ett flertal metoder testas med ändamålet att korrekt återge hur icke upplöst rörelsemängd växelverkar med de kemiska processThis work treats the modelling of PPC engine combustion through 3D computational fluid dynamics. In order to develop a cost-effective CFD model for the design and performance analysis of PPC engines it is important to first understand the multiple modes of combustion in PPC engines, e.g., the onset of the first ignition kernels, the propagation of the ignition/flame fronts, and the effect of charg

En ökning av andelen kollektivtrafik är en viktig del av omställningen mot lägre utsläpp av växthusgaser och mer energieffektiva transporter. I Sverige har antalet resor med kollektivtrafiken ökat med 18% mellan åren 2009 och 2015. Det finns dock en stor skillnad mellan olika regioner där ökningen varit över 20% i flera regioner medan utvecklingen av resandet har stagnerat, eller till och med mins

Context. In the advent of new infrared high-resolution spectrometers, accurate and precise atomic data in the infrared are urgently needed. Identifications, wavelengths, strengths, broadening, and hyper-fine splitting parameters of stellar lines in the near-infrared are in many cases not accurate enough to model observed spectra, and in other cases, these parameters do not even exist. Some stellar

This thesis deals with the addition of upconversion detection to non-linear mid-infrared laser spectroscopy techniques. The techniques investigated here are degenerate four wave mixing (DFWM) and infrared polarization spectroscopy (IRPS). These techniques are useful for detecting many of the key species in combustion, such as CH4, C2H6, HCl, and HCN. These species can be probed using ro-vibrationa
