DGEM (Devlabs, Copenhagen) is a small IoT product for air quality management and can be equipped with various integrated low-cost small sensors and hardware interfaces and provides comprehensive data collection capabilities. A one-month field observation test was conducted with reference instruments at Hyltemossa research station from 6th Dec. 2023 to 10th Jan. 2024 to validate this sensor bef
BACKGROUND/OBJECTIVES: High grade gliomas (HGG) are aggressive brain tumors, most frequently glioblastoma and astrocytoma grade 4. Methylation of O6-methylguanine-DNA methyltransferase (MGMT) promoter in HGG is crucial for temozolomide efficacy. As MGMT promoter methylation (MGMTpm) assessment requires tumor tissue, magnetic resonance imaging (MRI) is of interest for non-invasive prediction. We ai
Conflicts in traffic stream have been detected by different safety performance indicators. This study aims to empirically investigate the differences between different indicators in detecting rear-end conflicts and assessing the risk in an uninterrupted flow. Micro-level data of a 24-hr traffic stream (including 6,657 vehicles) were captured using inductive loop detectors installed on a rural free
Popular Abstract in Swedish SAMMANFATTNING PÅ SVENSKA (Swedish summary) Ultraljud används sedan 1970-talet rutinmässigt under graviditet. Undersökningen görs vanligen vid 17-18 graviditetsveckor och syftet med undersökningen är att datera graviditeten dvs bestämma tiden för beräknad förlossning. Man upptäcker också eventuella tvillingar vid denna undersökning. Redan tidigt visade det sig att visWe studied the prenatal detection rate of various malformations during a study period of 16 years in a population in southern Sweden consisting of 141 240 deliveries. The overall detection rate was 28.4% and the false positive diagnoses were very few. We studied the effect of prenatal diagnosis on the rate of spina bifida in southern Sweden compared with the rest of the country and could show tha
Popular Abstract in Swedish Fritidsaktiviteter bland personer med reumatoid artrit. Vad predikterar och hur mäter man? Fritidsaktiviteter ansågs redan i antikens Grekland leda till inre tillfredsställelse, mening och värde i livet. De genomfördes enbart för sin egen skull och utan tanke på belöning. I början av 1900-talet kunde fritidsaktiviteter endast genomföras av de personer som inte behövde Leisure Activities in Rheumatoid Arthritis. Associated Factors and Assessment. Leisure activities were considered to give intrinsic pleasure, meaning and value to life already in ancient Greek. It was also performed for its own sake and not by consideration of any external rewards. In the beginning of the 20th century leisure was only possible for wealthy people who could occupy themselves with n
Most computers today are embedded, i.e. they are built into some products or system that is not perceived as a computer. It is highly desirable to use modern safe object-oriented software techniques for a rapid development of reliable systems. However, languages and run-time platforms for embedded systems have not kept up with the front line of language development. Reasons include complex and, in
This report contains papers presented at a Research Seminar , or rather "workshop", organised by our Department. It is the third in a series. The previous seminars were held in 1993 and 19961• The seminar is "Nordic", by which is meant that the speakers came from the Scandinavian countries -Demnark, Norway, Sweden- and Finland. Certainly there are other Nordic countries in which frost is a real pr
The DEK oncogene is highly expressed in cells from most human tissues and overexpressed in a large and growing number of cancers. It also fuses with the NUP214 gene to form the DEK-NUP214 fusion gene in a subset of acute myeloid leukemia. Originally characterized as a member of this translocation, DEK has since been implicated in epigenetic and transcriptional regulation but its role in these proc
The luminescence from single quantum dots has been studied. Single dot photoluminescence was studied under continuous as well as under pulsed excitation. Time-resolved studies revealed fast relaxations in quantum dots. The time resolved measurements were fitted with a set of rate equations. Blinking in the luminescence was observed on a few quantum dots. The polarization of the emission from singl
Concatenation of several conventional convolutional encoders is a both powerful and practical method to obtain encoding schemes that are attractive for use in communication systems where very low error probabilities are needed. This thesis is devoted to woven convolutional codes, a construction where the constituent codes are woven together in a manner that resembles the structure of a fabric. A
The system dynamics technique has been demonstrated to be a proper method by which to model and simulate the development of spatial data infrastructures (SDI). An SDI is a collaborative effort to manage and share spatial data at different political and administrative levels. It is comprised of various dynamically interacting quantitative and qualitative (linguistic) variables. To incorporate lingu
This master’s thesis is about public libraries and how the work they do for children and youth in the summer holidays relates to public policy and reading research. Triangulation of methods is used with literature review, policy analysis, questionnaire survey and interviews. My primary theoretical framework is Carol Bacchi’s ’What’s the problem represented to be’ (WPR) approach, which is also us
Food insecurity in Zimbabwe is severe and increasing. The staple food is made from maize, which is highly sensitive to drought. The traditional small grains; finger millet, pearl millet and sorghum are drought resistant, nutritious and require little inputs compared to maize. Despite this, few farmers grow small grains even though they have been praised as a panacea. This thesis aims to narrow the
I början av 2017 presenterade regeringarna i Finland, Norge och Sverige ett förslag till en Nordisk Samekonvention. I förslaget erkänns urfolk som folk med en rätt till självbestämmande. Förslaget kan sägas följa på den utveckling som skett internationellt inom området för mänskliga rättigheter. Urfolk har, sedan ungefär 40 år tillbaka, fått en allt starkare rättslig ställning. Baserat på denna ut
In 2018, the Swedish government decided to invest 350 million SEK in welfare technology as a response to the increasing population of the elderly. The aim of this study was to investigate implementation managers’ descriptions of their work and use of welfare technology. The interviews were conducted at three long-term facilities for the elderly in the municipality of Burlöv, Helsingborg, and Hässl
Knowledge of the forest biomass and its change in time is crucial to understanding the carbon cycle and its interactions with climate change. LiDAR (Light Detection and Ranging) technology, in this respect, has proven to be a valuable tool, providing reliable estimates of aboveground biomass (AGB). The overall goal of this study was to develop a method for assessing AGB using a synergy of low poin
