Background Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental condition influenced by both genetic and environmental factors. Prenatal and perinatal exposures have been implicated in ASD etiology, but their influence may vary across clinical subgroups, including subgroups defined by co-occurring intellectual disability (ID). Methods We conducted a population-based case–control st
Polycyclic aromatic hydrocarbons (PAHs) of molecular mass (MM) 302 Da comprise numerous structural isomers that are of high concern for human health. Because of their multiplicity, low abundance in the environment, and limited availability of authentic standards, their occurrence, composition, and environmental health risk remain not well characterized. Here we extend the characterization of MM 30
This paper analyzes the effect of overlapping Trade blocs on Trade Facilitation. Using the time, documents and costs incurred as trade facilitation indicators, simulations show interesting yet important effects of an increase in Regional Trade Agreements on trade costs. The results suggest that when it comes to increasing regional trade agreements by 1%, costs are associated with an increase via t
Iron is an important material in the study of societies of the Iron Age and later periods. Not only does it give its name to the period it was also an integrated part in every humans’ life from the Iron Age and forward. And yet this material is many times just assumed to be there without much consideration of how it got there. In this master thesis, the author thus tries to bridge this gap in betw
In the Machine Learning field, more and more of the data collection is commercialised, even with monetary rewards to people and organisations for providing input data for models. Even if data collection is not associated with direct costs for the researcher, there are many cases where there are indirect, or circumstancial, costs associated with it. An established concept in game theory is "S
Understanding and managing charge carrier recombination dynamics is crucial for optimizing the performance of metal halide perovskite optoelectronic devices. In this work, we introduce a machine learning-assisted intensity-modulated two-photon photoluminescence microscopy approach for quantitatively mapping recombination processes in MAPbBr3 perovskite microcrystalline films at micrometer-scale re
Organic luminescent narrowband emitters have emerged as promising candidates for wide-color-gamut displays. However, the comprehensive photo-induced structural and vibrational dynamics responsible for the spectral broadening remain poorly understood. In this study, ultrafast spectroscopy is employed to elucidate the excited state dynamics of a sulfone-embedded narrowband emitter, 2tCPD. An intrins
Reducing the excitation threshold to minimize the Joule heating is critical for the realization of perovskite laser diodes. Although bound excitons are promising for low threshold laser, how to generate them at room temperature for laser applications is still unclear in quasi-2D perovskite-based devices. In this work, via engineering quasi-2D perovskite PEA2(CH3NH3)n-1PbnBr3n+1 microscopic grains
BACKGROUND: Most cerebral palsy (CP) cases have an unexplained etiology, but a role for environmental exposures has been suggested. One purported environmental risk factor is exposure to endocrine-disrupting pollutants specifically per- and polyfluoroalkyl substances (PFAS).OBJECTIVES: We investigated the association between prenatal PFAS exposures and CP in Swedish children.METHODS: In this case-
ObjectiveTo determine the feasibility of a digitally automated population-based programme for organised prostate cancer testing (OPT) in Southern Sweden.Patients and MethodsA pilot project for a regional OPT was conducted between September 2020 and February 2021, inviting 999 randomly selected men aged 50, 56, or 62 years (y). Risk stratification was based on PSA, PSA density (PSAD), and biparamet

Research question: In what way has Swedbank applied accounting communication surrounding the money laundering scandal and how has the communication developed and changed over time along the course of the event? Purpose: The purpose of the study was to examine how Swedbank applied accounting communication in order to manage and rebuild their reputation in connection to the money laundering scandal
Global wind power capacity has greatly increased in the last decades and is in certain areas constituting a significant share of generating capacity. This thesis examines wind power production data along with prices and inter-regional trade volumes on the Nordic electricity market Nord Pool Spot to deduce the effects of wind power on the grid. The research focused on Denmark, since it gets a very
På Galgbackens vattenanläggning i Hässleholm tillämpas bassängsinfiltration genom återinfiltration av grundvatten i en isälvsavlagring. Syftet är att kunna leverera dricksvatten med god kvalitet till konsumenterna. Grundvattnet tas från brunnar i Ignaberga och Tyringe och återinfiltreras i isälvsavlagringen. Syftet med detta examenstarbete är att genom en spårämnesstudie undersöka uppehållstid ochGalgbacken water plant in Hässleholm is applying basin infiltration by re- infiltrating groundwater into a glaciofluvial deposit. The purpose is to supply drinking water with good quality to the consumers. Groundwater is pumped from wells in Ignaberga and Tyringe and re- infiltrated into the glaciofluvial deposit. The aim with this thesis is to examine retention and dispersion of the re- infiltrat
This thesis examines the influence of a foreign-born background on students’ educational choices in Sweden, focusing on the selection between vocational and university preparatory programmes in upper secondary education (gymnasium). Recognising that personal experiences and social contexts shape such decisions, a qualitative methodology was adopted to explore the underlying motivations and influen
The decline in areal BMD (aBMD) in men may start as early as age 19, but it is debated whether proximal femoral strength follows the same pattern. We measured FN aBMD in a cross-sectional cohort of 1101 men aged 18-28 yr with two-dimensional DXA. Body height, weight, jump height, grip strength, and maximum knee extension torque muscle strength were measured with standard tests, after which BMI was
Preparative chromatography is an important process step for separation and purification of fine chemicals, pharmaceuticals, and other biotechnical products. The technique mainly used in the pharmaceutical and fine chemistry industries is single-column batch chromatography (BC). The major drawback of BC is the trade-off between product purity and process performance. A high purity of the product co
The aroma components of herbs and spices are very sensitive to heat, complicating their drying process. Until now, exporters of dried herbs face the challenge of low total phenolic contents and efforts are constantly being made to improve the drying efficiency of herbs and conserve their aroma. This thesis looks at the influence of extracellular trehalose impregnated by vacuum impregnation (VI) an
Cancer-associated gene fusions resulting in chimeric proteins or aberrant expression of one or both partner genes are pathogenetically and clinically important in several hematologic malignancies and solid tumors. Since the advent of different types of massively parallel sequencing (MPS), the number of identified gene fusions has increased dramatically, prompting the question whether they all have
Evaporation is an important component of the water and energy balance of lakes and reservoirs. The energy balance combination method for estimating evaporation requires the heat storage changes (Qt) to be known. The lack of data on water temperature profiles and water depth fluctuations hinders routine computations of Qt. Following successful estimation of the soil heat flux density of land surfac
