For almost a century, the knock-resisting ability of a spark ignition fuel has been quantified with the RON and MON indications, conforming to the corresponding ASTM-D2699 and D2700 methods, respectively. These testing methods rely on specific pressure pickup technology that acts like a low-pass signal filter, thereby cutting off high frequency cylinder pressure information. Within a second-genera

Soft colloids are increasingly used as model systems to address fundamental issues such as crystallization and the glass and jamming transitions. Among the available classes of soft colloids, microgels are emerging as the gold standard. Since their great internal complexity makes their theoretical characterization very hard, microgels are commonly modeled, at least in the small-deformation regime,

Security and sustainability are prioritized goals in the “Western liberal” world. Maintaining democratic resources while simultaneously strengthening society’s ability to deal with security issues firmly resonates with ideals associated with social sustainability. However, merging normative theories like security and social sustainability produces conceptual difficulties that are hard to resolve.

Furfural is an intermediary toxic aldehyde compound produced during heat-induced food processing and storage. Furfural is also formed by the degradation of cellulosic insulation in oil-immersed electric potential transformers, whose level is an important indicator of aging for replacement. In this study, we report a new means to detect the trace level of furfural in a colorimetric manner. Furfural

Congenital diaphragmatic hernia (CDH) is a severe birth defect frequently associated with pulmonary hypoplasia, pulmonary hypertension, and heart failure. Since amniotic fluid comprises proteins of both fetal and maternal origin, its analysis could provide insights on mechanisms underlying CDH and provide biomarkers for early diagnosis, severity of pulmonary changes and treatment response. The stu

Aims: Mineralocorticoid receptor antagonists (MRAs) improve outcomes in heart failure with reduced ejection fraction (HFrEF) but remain underused and are often discontinued especially in patients with chronic kidney disease (CKD) due to concerns on renal safety. Therefore, in a real-world HFrEF population we investigated the safety of MRA use, in terms of risk of renal events, any mortality and an

Objective: We investigated diagnostic utility of phosphorylated tau 217 and 181 (ptau217, ptau181), glial fibrillary acidic protein (GFAP), amyloid beta 42 and 40 (Aβ42, Aβ40), and neurofilament light (NfL) to distinguish biomarker-defined Alzheimer disease (AD) from non-AD conditions, in a heterogenous clinical cohort of younger people. Methods: Plasma biomarkers were analysed using ultrasensitiv

Context: Global change is leading to more frequent and intense tree damage and mortality events. Drought-induced tree mortality is occurring worldwide leading to broad-scale events, but the spatial patterns of tree damage and mortality, their underlying drivers and their variation over time is largely unknown. Objectives: We investigated the spatial patterns of tree damage and mortality across Med

DNA-encoded chemical libraries (DECLs) interrogate the interactions of a target of interest with vast numbers of molecules. DECLs hence provide abundant information about the chemical ligand space for therapeutic targets, and there is considerable interest in methods for exploiting DECL screening data to predict novel ligands. Here we introduce one such approach and demonstrate its feasibility

Background: Unplanned pregnancy is significantly associated with an increased risk of perinatal depression (antenatal and postnatal depression), emphasizing its prevalence and its potentially detrimental effects on both maternal and child health. This study aimed to investigate the association of contraception use and pregnancy intention with the risk of perinatal depression among Omani mothers. M

Characterizing ore deposits or mining dumps in terms of mineral content and grain size remains a challenge. Since the 1950s the induced polarization (IP) method has been successfully applied in ore prospecting. However, reliably interpreting field survey data requires comprehensive laboratory studies to establish a link between the IP parameters from empirical or phenomenological models and the typ

This thesis illuminates the deliberative democratic ideal's claim for efficiency and legitimacy that is brought forward by Robyn Eckersley and John S. Dryzek as being an essential brick in the struggle for a societal development that is ecologically sustainable. The take off lies in the belief that the current liberal democracy is incapable of responding sufficiently to the ecological problems

Due to the increasing expectation in society that companies act responsibly and take into account the constraints of the natural environment, there is a growing need to manage the environmental challenge in a way, if possible, that contributes to overall competitiveness. The purpose of this thesis is to identify how environmental initiatives contribute to competitiveness, considering a specific t

På vilka värderingar och grundläggande teorier baserar sig vårt rättsystem och vad är lagens bindande kraft? Hur kan dessa teorier förklara klyftan mellan moraliska regler och lagregler? Denna uppsats består av tre delar. De två första delarna [Kap. 2 och 3] är mer deskriptiva och består dels av ett kapitel om illegal fildelning, dels av en analys av skandinavisk rättsrealism, framför allt VilhelThe general moral attitude is, to consider copyright infringements on the Internet as a socially acceptable behaviour. While the record industry and judicial system have both monetary and other reasons to fight illegal file sharing, both the technological and the moral development are combating these efforts. The legal realism as represented by Vilhelm Lundstedt is based on the idea that the lega

This paper deals with the question of the ne bis in idem rule, known in the Common Law Countries as 'double jeopardy'. The rule's purpose is to protect a person from being prosecuted or sentenced for an offence a second time, for which he or she had already been tried, whether convicted or acquitted. The paper comprises two parts: the first is related to the question of the ne bis in i

Purpose: The study aims to answer the following questions: Which are the ethical investment criteria of institutional investors and by what means do Institutional Investors enforce their ethical investment criteria? In order to answer the purpose the thesis aims to: To construct a theoretical framework which serves as a basis to identify and describes the ethical criteria and enforcement means of

ABS is the third objective of the Convention on Biological Diversity (CBD) and the acronym for access to genetic resources and benefit-sharing, the legal-technical term designating the practice of collecting biological resources from nature. Rhetorically this practice is either designated as bio-prospecting or as biopiracy. The current regulation of ABS is found in Article 15 of the CBD. The imple

Anna, Manager.Background: An idea to replace metal foil with a printed pattern of metal paste (metal powder mixed with solvent and binder) and incorporate this into current production was born.
