Critical infrastructures must be both robust and resilient in order to ensure the functioning of society. A key activity in ensuring their proper function is finding and addressing system weaknesses by the means of risk and vulnerability analysis. A critical factor of such analysis is the ability to determine the negative consequences of various types of contingencies. Numerous mathematical and si
Arsenic contamination of drinking water is a result of natural and/or anthropogenic activities, causing undesirable detrimental effects on the environment and the human health. Herein, an integrated process based on Membrane Distillation (MD), photocatalysis and Polymer-enhanced Ultrafiltration (PEUF) was developed for an effective remediation of arsenic (As). This approach, whose effectiveness wa
An improved understanding of past interactions between terrestrial vegetation and various forcings, such as climate change, human impact, and paleofire, is crucial for assessing impacts of future global change on terrestrial ecosystems. This study seeks to find the key factor or factors that have driven Holocene vegetation change along the East Asian monsoon margin. Several high-resolution pollen
Marina sediment kan stabiliseras med ultrahöghållfasta bindemedel: cement, Cement Kiln Dust (CKD) och slagg. Egenskaperna hos den stabiliserade jorden indikerar potential för återanvändning. Den här studien undersökte prestandan för den enaxiella tryckhållfastheten (UCS) i smarina sediment stabiliserade med bindemedel (cement, CKD, slagg), testade med ultraljuds P-vågor. Material omfattar 194 prov
The intensifying effects of climate change are becoming one of the main threats to cultural heritage, posing risks of degradation or destruction. Climate change is bringing complexity and uncertainty to ensuring the resilience of cultural heritage, and among risk mitigation measures digitalisation is regarded as a promising tool. However, the infrastructure required for the digitalisation process
Smooth muscle participates in forming the wall of hollow organs, tracts, and blood vessels. Therefore, it plays a critical role in mediating vital functions in the body including regulation of blood pressure. In response to changes in the surrounding microenvironment, smooth muscle cells can modulate their phenotype and dedifferentiate from being quiescent contractile to a more proliferative and m
Awiggler is a high-power insertion device that was used in the past to produce a smooth wide-band X-ray spectrum. It is widely believed that on low-emittance synchrotrons this X-ray source loses its spatial and spectral homogeneity and therefore becomes less ideal than a scanning undulator. In this paper, we report on experimental and computational studies of an in-vacuum wiggler installed on the
Ethics is always at stake in qualitative health and nursing research. The article examines and discusses research ethical dilemmas in qualitative health research, with a special focus on collaborative research. Firstly, the article discusses challenges with gatekeepers influencing the recruitment of informants when planning and executing interviews and participant observations. Secondly, the artic
The total of catalytic particles is often unavailable to participate in the electrochemical reactions in a PEFC, which limits the PEFC performance. The electrochemical surface area (ECSA) becomes an important metric to diagnose the catalyst layer's performance and evaluate the development of new electrode materials to achieve better overall efficiency. This work intends to analyze the effects of a
CONTEXT: The natural course of HIV disease progression among resource-poor patient populations has not been clearly defined.OBJECTIVE: To describe predictors of HIV disease progression as seen at an outpatient clinic in a resource-limited setting in rural Ethiopia.DESIGN: This prospective cohort study included all adult HIV patients who visited an outpatient clinic at Arba Minch hospital in South
Knowledge, when used effectively, is a major input for development. However, the processes associated with knowledge production, knowledge transfer, and knowledge use are complex and not easy to facilitate in certain parts of the world. This is mainly due to a lack of or limited interactions between knowledge producers and knowledge users. This thesis aims to explore how efforts to foster knowledg
A search for charged leptons with large impact parameters using 139 fb-1 of s=13 TeV pp collision data from the ATLAS detector at the LHC is presented, addressing a long-standing gap in coverage of possible new physics signatures. Results are consistent with the background prediction. This search provides unique sensitivity to long-lived scalar supersymmetric lepton partners (sleptons). For lifeti
The stringent response is a central adaptation mechanism that allows bacteria to adjust their growth and metabolism according to environmental conditions. The functionality of the stringent response is crucial for bacterial virulence, survival during host invasion as well as antibiotic resistance and tolerance. Therefore, specific inhibitors of the stringent response hold great promise as molecula
Wastewater heat recovery upstream of wastewater treatment plants (WWTP) poses a risk to treatment performance, i.e. the biological processes. In order to perform a sustainability analysis, a detailed prediction of the temperature dynamics over the WWTP is needed. A comprehensive set of heat balance equations was included in a plant-wide process model and validated for the WWTP in Linköping, Sweden
BACKGROUND: Nosocomial outbreaks of coronavirus disease 2019 (COVID-19) can have devastating consequences from both a resource cost and patient healthcare perspective. Relying on reverse transcription-polymerase chain reaction (RT-PCR) for identifying infected individuals may result in missed cases. Screening for antibodies after an outbreak can help to find missed cases and better illuminate rout
