I en studie av neutralisationskapaciteten och kalkstenshalten i Sydvattens infiltrationsområde vid Vomb har fem prover från olika platser i fältet samlats in, siktats och surgjorts med saltsyra. Neutralisationskapaciteten mätt som kalciumkarbonathalt befanns variera i de olika sandproverna men var generellt hög (ca 2–14 % som vikt). Den totala massan av kalciumkarbonat i infiltrationsområdet bestäIn a study of the neutralization capacity and limestone content the artificial recharge area of the Sydvatten waterworks Vombverket in Vomb, Skåne, five samples from different locations in the area was collected, sieved and acidified with hydrochloric acid. The neutralization capacity measured as calcium carbonate content was found to vary in the different sandy soil samples but was generally high

High levels of ADAM17 activity have emerged as an important mediator in severe COVID-19. This study aims to characterize eventual causal relationships between ADAM17 and COVID-19. Using Mendelian randomization analyses, we examined the causal effects of circulating ADAM17 on COVID-19 outcomes using summary statistics from large, genome-wide association studies of ADAM17 (up to 35,559 individuals)

BACKGROUND: Research indicates that among the risks associated with young people's alcohol and illicit drug use are sexual risks. However, insights into co-occurrence of substance use and sexual risks in adolescent samples and possible differences across countries are limited. METHODS: A sample of 1449 adolescents from Belgium, Sweden, the Czech Republic, and Germany screened positive for risky al

We investigate the propagation of environmental performance among competitors and in customer–supplier relationships. We find causal effect among competitors, while the propagation from customers to suppliers and vice versa appears insignificant or does not survive identification tests. The effect is stronger among firms in highly concentrated competitor networks and towards firms with less market

This study conducted the global sensitivity analysis of the APSIM-Oryza rice growth model under eight climate conditions and two CO2 levels using the extended Fourier Amplitude Sensitivity Test method. Two output variables (i.e. total aboveground dry matter WAGT and dry weight of storage organs WSO) and twenty parameters were analyzed. The ±30% and ±50% perturbations of base values were used as th

Although literature concerning chronic pain patients indicates that cognitive behavioural variables, specifically acceptance and fear of movement/(re)injury, are related to life impact, the relative roles of these factors in relation to pain characteristics (e.g. intensity and spreading) and emotional distress are unclear. Moreover, how these variables affect rehabilitation outcomes in different s

The nutrient intake in geriatric long-stay patients and the mortality risk associated with low energy intake were studied in 61 patients, 43 women and 18 men, with a mean age of 87 years, at a geriatric long-stay care hospital during a 6-month follow-up. Dietary intake was assessed with a 9-day dietary record. Energy expenditure was calculated assuming a physical activity level of 1.33 × basal met

In order to facilitate bone graft harvesting and to get more mouldable bone graft in posterolateral fusions of the lower lumbar spine, a modified technique of bone graft harvesting was utilized. Through a midline skin incision the most posterolateral part of an iliac crest was ground with a reamer to a smooth bone paste. The technique was used in lumbar posterolateral fusions without osteosynthesi

The use of learning-based methods for vehicle behavior prediction is a promising research topic. However, many publicly available data sets suffer from class distribution skews which limits learning performance if not addressed. This paper proposes an interaction-aware prediction model consisting of an LSTM autoencoder and SVM classifier. Additionally, an imbalanced learning technique, the multicl

This thesis describes studies regarding the design, synthesis, and analysis of new types of electro-responsive [8]annulene-based switches.A starting material for the targeted material is dibenzo[a,e]cyclooctatetraene (dbCOT). The first part of the thesis describes an improved synthesis of this structure using a copper(I) catalyzed decarboxylative approach. Using this method, dbCOT was prepared in

Introduction: Drawing upon the framework of life course epidemiology, this study aligns with research on the mental health consequences of significant social transitions during early adulthood. The focus is on the variation in initial labour market attachment and the development of depressiveness, assuming that a firm attachment is associated with decreasing depressiveness. Methods: The baseline i

Surface emissions of CO2 from fossil fuel combustion (ΦFFCO2) are estimated for the Netherlands for the period of May 2006-June 2009 using ambient atmospheric observations taken at station Lutjewad in the Netherlands (6°21'E, 53°24'N, 1 m. a.s.l.). Measurements of Δ14C on 2-weekly integrations of CO2 and CO mixing ratios are combined to construct a quasi-continuous proxy record (FFCO2*) from which

Police crash reports are often the main source for official data in many countries. However, police sampling and data are known to be subject to bias, making the countermeasures adopted according to them possibly inefficient. In the case of bicycle crashes, this bias is most acute and it probably varies across countries, with some of them being more prone to reporting accidents to police than othe

Reliable information on solar activity over the Holocene period is important to predict the Sun in the future and to understand the mechanism behind the Sun-climate linkage. Presently, there are discrepancies in the proxy data of solar activity due to reasons that are not yet understood. This leads to major uncertainties in Holocene solar reconstructions. This PhD project aims to improve the Holoc

Purpose To evaluate dose plans for head and neck organs at risk (OARs) for classical Hodgkin lymphoma (HL) patients using involved node radiotherapy (INRT) delivered as 3D conformal radiotherapy (3DCRT), volumetric modulated arc therapy (VMAT), and intensity modulated proton therapy (PT), in comparison to the past mantle field (MF). Materials and methods Data from 37 patients with cervical lymph n

The identification, prevention, and prompt treatment of exacerbations are major objectives of asthma management. We looked at change in PEF, symptoms, and use of rescue beta-agonists during the 425 severe exacerbations that occurred during a 12-mo parallel group study (FACET) in which low and high doses of budesonide with and without formoterol were compared in patients with asthma. Oral corticost
