This paper presents two procedures for the determination of four selective serotonin reuptake inhibitors (citalopram, paroxetine, fluoxetine, and sertraline) and one metabolite (norfluoxetine) in sewage sludge utilizing three-phase hollow fiber liquid-phase microextraction (HF-LPME). First, direct HF-LPME was used for extraction, clean-up, and preconcentration. The pharmaceuticals were extracted f
There are various transport phenomena (gas-phase species, heat, and momentum) occurring at different length scales in anode-supported solid oxide fuel cells (SOFCs), which are strongly affected by catalytic surface reactions at active triple-phase boundaries (TPBs) between the void space (for gas), Ni (catalysts for electrons), and YSZ (an electrolyte material for ions). To understand the multisca
A direct numerical simulation (DNS) coupling with multi-zone chemistry mapping (MZCM) is presented to simulate flame propagation and auto-ignition in premixed fuel/air mixtures. In the MZCM approach, the physical domain is mapped into a low-dimensional phase domain with a few thermodynamic variables as the independent variables. The approach is based on the fractional step method, in which the flo
The impact of the operating Ignalina Nuclear Power Plant (INPP) on the contamination of top soil layer with artificial radionuclides has been studied. Results of the investigation of artificial gamma-ray emitting radionuclide distribution in soil in the vicinity of the INPP and distant regions in Lithuania in 1996-2008 (INPP operational period) show that nowadays Cs-137 remains the most important
Background:Observational studies have mostly found no association between self-reported whole-grain (WG) intake and prostate cancer (PCa). Plasma alkylresorcinol metabolites have been suggested as biomarkers for WG intake in free-living populations. Methods:We investigated the major dietary and lifestyle determinants of plasma alkylresorcinol metabolites in a nested case-control study (1,016 cases
The timing of birth is often correlated with offspring fitness in animals, but experimental studies that disentangle direct effects of parturition date and indirect effects mediated via variation in female traits are rare. In viviparous ectotherms, parturition date is largely driven by female thermal conditions, particularly maternal basking strategies. Our field and laboratory studies of a vivipa
The increasing number of new psychoactive substances made available for recreational drug use has created a challenge for clinical toxicology and drug testing laboratories. As a consequence, the routine immunoassay drug testing may become less effective due to an increased occurrence of false negative and false positive screening results. This work aimed to extend the knowledge about analytical cr
Gas cooling is a technique used within the fire service to reduce the risks of the hot gaseous layer and create a better visibility. It is achieved by applying water into the gaseous layer. Successfully performing or implementing this technique is something that has not yet been accomplished in every brigade. This work has been focused on different parameters that affect gas cooling and is studie
The underlying values people hold in relation to the environment is an important aspect to consider when natural areas are shared. These underlying values, so called value orientations, and differences in values directed towards a natural phenomenon can impact views on suitable management, lead to disagreements and even conflict. Understanding of the diverse aspects people value can therefore be i
Under de senaste åren har södra halvklotet och den vidsträckta Södra oceanen fått ökad upp-märksamhet och betydelse inom det vetenskapliga samfundet med avseende på globala klimatförändringar och den globala CO2-cykeln, särskilt vad gäller förhållandena under senaste istidsmaximum (Last Glacial Maximum, LGM) och holocen. Man menar att Västvindbältet på södra halvklotet (Southern Hemisphere WesterlIn recent years, the Southern Hemisphere (SH) and the vast Southern Ocean (SO) have gained awareness and importance within the scientific community in relation to global climate change and the global CO2 cycle, par-ticularly since the Last Glacial Maximum (LGM) and into the Holocene. It is believed that the Southern Hemi-sphere Westerlies (SHW) play a key role in regulating climate change in the m
Examensarbetets titel: Vad är service värt? Seminariedatum: 2016-01-15 Ämne/kurs: FEKH29 Företagsekonomi: Examensarbete i marknadsföring på kandidatnivå, 15 högskolepoäng Handledare: Magnus Lagnevik Syfte: Att undersöka sambandet mellan servicekvalitet och svenska flygresenärers vilja att betala en prispremie vid köp av flygresa. Metod: Med hjälp av kvantitativ metod och en deduktiv ansats dä
Introduction: There is a need for risk stratification of emergency department (ED) chest pain patients. The Global Registry of Acute Coronary Events risk score (GRACE RS) predicts adverse events in patients with confirmed acute coronary syndrome (ACS), and has been validated on unselected ED patients with chest pain. Clinical gestalt is the unstructured overall clinical assessment, based on the ph
Aim and Purpose: The aim with this thesis was to provide answers to the two research questions: “Which of the four consumption models (“Circular economy”, “Shared economy”, “Environmentally friendly”, and “Conventional”) do Swedish consumers prefer, in relation to different product markets and product categories?” and“Are there any distinctive demographic segments among consumers preferring a spec
Networks have been recognized as an alternative internationalization approach for Professional Service Firms (PSFs). However, the exploration of tensions, which result from attempts to unite network members and at the same time support their diversity, has been rather neglected in the past. Furthermore, the role of local embeddedness in the presented setting seems to have been overlooked. We have
The United States has the highest incarceration rate in the world. The phenomenon of mass incarceration largely confines minorities and people living in poverty. More than 600,000 prisoners are released yearly to face barriers of reentering society. Struggles of finding employment, housing, and being denied social services, due to their criminal record, generate a system where former inmates becom
Världen är för närvarande på väg mot 3°C av global uppvärmning pga globala koldioxidutsläpp. Kunskapen som krävs för att minska utsläppen existerar, men de radikala sociala och politiska förändringar som behövs sker hittills inte snabbt nog. Nuvarande politiska och ekonomiska paradigm hyllar koldioxidprissättning som antingen den enda lösningen, alternativt som en del av lösningen. Denna uppsats tThe world is currently heading for 3°C of global warming due to global excessive carbon emissions, and while science is producing the knowledge necessary to combat it, the radical change needed is not coming fast enough. Current political and economic paradigms hail carbon pricing as either the, or part of the solution to our carbon emissions problem. This thesis looks at the available (although l
Belgium is celebrated for its progressive LGBTI legislation, ranking second on the ILGA index. At the same time Belgian LGBTQIA+ people experience alarmingly high rates of violence and fear. This thesis examines two competing narratives about the relationship between LGBTI legislation and LGBTQIA+ experiences of safety: (1) ‘LGBTQIA+ safety requires state protection’; and (2) ‘LGBTQIA+ safety requ
Following the collapse of socialism in 1989, Eastern European countries experienced rapid socio-spatial reorganization causing a significant loss of urban greenspace (UGS). Greenspaces provide socio-environmental benefits, making them a crucial component of urban sustainability. This study explores the development of greenspace in Plovdiv (Bulgaria), which serves as a case study to understand disc
