In this study, laminar burning velocities (LBV) of ammonia in oxygen-enriched air (oxygen content ranging from 30 to 50 vol%) were investigated under various initial temperatures (298, 323, and 348 K) at a pressure of 1 atm, employing the heat flux method. Our measurements reveal substantial disparities with previously published data primarily obtained using the spherical flame method. The reliabi
We investigate the behaviors used by households to economize on their spending on food using data from a budget survey of urban households in sweden in 1913-1914. Higher-income households bought higher quality varieties of both luxury and staple foods. But changing the composition of the diet was a much more important way to adjust spending on food than changing the quality of the foods bought. Hi
This thesis offers a cultural analysis of climate change, modernisation and sustainable development in the pastoral landscape of Baringo, Northern Kenya. For the majority of the pastoralists living there, life is defined by crippling poverty, ethnic violence and an increasingly erratic and unpredictable climate. In response, a growing number of people have moved away from the traditional reliance
Lunds universitet rankas som topp-tio i världen inom forskning på detaljhandel och logistik. Helsingborgsregionen delar på förstaplatsen i Sverige vad gäller bästa logistikläge. Det här ger en bra bas för Lunds universitets satsning REAL – Center for Retail and Logistics – på Campus Helsingborg. Detta centrum profilerar sig med hållbarhet, digitalisering och förändrat arbetsliv och lyfter också fr
In the Holocaust’s immediate aftermath (1945–1946), a small gallery in Lund, Sweden exhibited the paintings and drawings of Polish artist Jadwiga Simon-Pietkiewicz, which depicted her former fellow inmates in the Ravensbrück concentration camp. This exhibit and subsequent exhibitions elsewhere in Sweden marked rare instances of early postwar Holocaust art displayed in a country that had been relat
This paper introduces a new framework – RoadRAT - to calculate the probability of inundation, wave runup, and storm erosion impacting coastal roads. Extreme value analysis is applied to annual maxima of observed and simulated still water level levels (SWL), total water levels (SWL + runup), and storm erosion volumes. The probability of impact on the road is derived both for the present conditions
Harvey's capital switching thesis is one of the most influential contributions of Marxist geographers, providing a framework for understanding structural determinants of capital flows into urban land and built environments. Harvey's thesis has drawn criticism in subsequent debates for its lack of direct empirical support. Even decades later, several gaps remain. The most comprehensive intervention
1. Cytochrome P450 2D (CYP2D) protein is widely expressed across brain regions in human and rodents. We investigated the interactions between tramadol, a clinically used analgesic, and brain CYP2D regulators, by establishing concentration-time curves of tramadol and O-desmethyltramadol (M1) in rat cerebrospinal fluid (CSF) and plasma, as well as by analyzing the analgesia-time course of tramadol.
Recently, it has become a focus to reduce non-exhaust aerosol emissions from the transport sector. One possible way to decrease brake particle emissions is by laser-cladding coatings onto brake discs. This work tested five different laser-cladding coated brake discs against a non-asbestos organic brake pad. The performance of these coatings was compared to a commercial grey cast iron brake disc te
To address the challenges of an ageing population, it is important to promote health by identifying factors for healthy ageing. The aim of this study was to investigate the bidirectional association between physical activity (PA) and sleep in healthy Japanese super-seniors over the age of 80. For approximately 1 year, 124 participants wore wearable devices and answered daily lifestyle questionnair
The paper identifies three interconnected scales of global politics in Artificial Intelligence (AI) and healthcare. It provides a multilevel framework for policy makers to situate hybrid-human AI collaborations in healthcare within broader global political concerns.
The aim was to describe hematopoietic stem cell (HSC) donors' experiences focusing on information and side effects during the first year after donation. Our prospective Swedish cohort study with adult HSC donors was performed from 2019 to 2022, with questionnaires at four time points from before until 12 months after donation. 173 unrelated and 68 related donors participated, and the majority dona
Introduction: Ambient air pollution and road traffic noise are stroke risk factors, but evidence on their potential joint effects remains limited. This study investigated the independent and joint associations of air pollution and road traffic noise on stroke incidence using both multiplicative and additive scales. Methods: We followed stroke incidence in ten cohorts in Sweden, Denmark, and Finlan
A new synthetic absorbent, sylopute was applied for the purification of paclitaxel from plant cell cultures and yew tree. There was selective absorption of impurities in the treatment of sylopute. Therefore, higher purity paclitaxel could be obtained simply in the following process with a higher yield than with active clay or activated carbon. The purity of crude paclitaxel after sylopute treatmen
Background: Skin pain is a common symptom in patients with chronic hand eczema (CHE); however, its association with increased analgesic use has not been thoroughly investigated. Objectives: To examine analgesic use (paracetamol, nonsteroidal anti-inflammatory drugs [NSAIDs], opioids and gabapentin/pregabalin) among patients with CHE compared to a control group. Methods: Data were obtained from the
Boreal lakes are generally seen as sources of carbon dioxide (CO2) to the atmosphere, even though a part of them are periodically undersaturated with CO2 and have the potential to be net-autotrophic. This undersaturation is the result of photosynthetic activity by phytoplankton, especially flagellated species like Gonyostomum semen, which form high-biomass blooms in brown water lakes. We hypothesi
OBJECTIVES: This study examines the associations between ten family structure types and delinquency, including four groups of symmetrical and asymmetrical living arrangements. We also adjust for attachment to parents and parental monitoring. METHODS: Data are drawn from four cross-sectional surveys conducted between 2016 and 2019 in southern Sweden. The sample consists of 3,838 adolescents, aged 1
Background: In opioid replacement therapy (ORT), drug testing is performed continuously to ensure that patients are taking their prescribed medication, and to detect whether they have taken other, non-prescribed, substances. Typically, supervised urine testing is conducted, and in Sweden such testing is often an ORT precondition. Aim: This study investigates ORT patients’ experiences of and views
Purpose of Review: This review synthesizes current knowledge of the aggregation pheromones of Ips bark beetles specialized on coniferous hosts. The pest potential of these insects is increasing globally due to climate change and anthropogenic disturbances. The high aggressiveness of some species results from coordinated mass attacks on trees, mediated by male-produced aggregation pheromones. Bring
