Performance and emissions of a high-speed marine dual-fuel engine operating with methanol-water blends as a fuel
Dual-fuel (DF) operation with methanol-diesel allows to reduce CO2 emissions, increase efficiency and decrease NOx and soot. This paper describes the experimental results with methanol-water (MeOH-W) blends as a fuel, and has three objectives: (1) whether water acts as a knock suppressant, enabling higher diesel substitution ratios, (2) if water can be a measure to control engine-out NOx emissions
"Just i vårt yrke är det lättare att blunda om klienter är otrevliga... man förväntar sig det till en viss del" En kvantitativ studie om socialarbetares upplevelse av klienters otrevliga bemötande och dess påverkan
The past couple of decades have seen an increase in threats and violence from clients toward social workers. One of the most important parts of social work is the workers' meetings and interactions with the clients to ensure that the client can get access to the help and resources that they need. The aim of this study has been to depict the difference in the occurrence of positive and negative
Elever saknar erfarenhet av skolans narkotikaförebyggande insatser - En kvantitativ studie om gymnasieelevers erfarenheter av och uppfattning om narkotikaförebyggande insatser
It is important to investigate and better understand what drug prevention interventions look like for young people in society. The purpose of the study was to investigate adolescents' experiences of and perception of the support and prevention efforts that are available for them. The method used in this study was a survey, with a sample consisting of 200 students from two high schools in Helsi
Validation and atmospheric exploration of the sub-Neptune TOI-2136b around a nearby M3 dwarf
Context. The NASA space telescope TESS is currently in the extended mission of its all-sky search for new transiting planets. Of the thousands of candidates that TESS is expected to deliver, transiting planets orbiting nearby M dwarfs are particularly interesting targets since they provide a great opportunity to characterize their atmospheres by transmission spectroscopy. Aims. We aim to valida
Parametric Analysis and Optimization of Vanillin Hydrodeoxygenation Over a Sulfided Ni-Mo/δ-Al2O3 Catalyst Under Continuous-Flow Conditions
A fundamental understanding of the process parameters affecting the catalytic hydrodeoxygenation (HDO) of bio-oils is of significance for enabling further progression and improvement of industrial biofuel upgrading methods. Herein, a novel demonstration and evaluation of the effect of temperature, pressure, and weight hourly space velocity in the continuous HDO of vanillin to cresol over a Ni-Mo/δ
A reflexive perspective on public relations : On leaving traditional thinking and uncovering the taken-for-granted
Nöden har ingen lag. Om demokratins överlevnad i en ’akut nödsituation’ : En reflektion över Sverige 2015
Allt våldsammare deportationer. Fler oskyldiga människor i fängsligt förvar. Fler svårt sjuka barn som skickas till länder där det är högst osäkert om de kan få vård. Ett stigande antal föräldrar som tar med sig sina barn på sjöodugliga båtar över medelhavet för att undvika mångårig separation. En växande mängd ungdomar som lever ett liv i papperslöshetens skuggsamhälle. Detta är några sannolika f
Realization of multi-input/multi-output switched linear systems from Markov parameters
This paper presents a four-stage algorithm for the realization of multi-input/multi-output (MIMO) switched linear systems (SLSs) from Markov parameters. In the first stage, a linear time-varying (LTV) realization that is topologically equivalent to the true SLS is derived from the Markov parameters assuming that the discrete states have a common MacMillan degree and a mild condition on their dwell
Image Stitching with Locally Shared Rotation Axis
We consider the problem of stitching image sequences with cameras undergoing pure rotational motion. We leverage the assumption of a locally constant rotation axis, i.e., neighboring frames have a shared but unknown rotation axis. This assumption holds in many common image capturing scenarios, e.g., panoramic sweeping motions. Using this additional constraint, we develop techniques for three-view
Constructing clickable criminal trials: : Framing trials and legal professionals in digital news reports
Journalistic live blogging entails the conundrum of capturing emotions in a context where they should be absent in order to snap up the sensational in the subtle drama of the courtroom and present it in a way that attracts readers, thus making it clickable.Applying an inductive frame analysis of live blogs and drawing on criteria of newsworthiness and an emotion sociological framework, this articl
Machine learning-assisted macro simulation for yard arrival prediction
Increasing the modal share of the single wagonload transport in Europe requires improving the reliability and predictability of freight trains running between the yards. In this paper, we propose a novel machine learning-assisted macro simulation framework to increase the predictability of yard departures and arrivals. Machine learning is applied through a random forest algorithm to implement a ya
Experiences of Equine Assisted Therapy and Its Influence on Occupational Engagement Among People With Mental Health Problems
Equine Assisted Therapy (EAT) has positive influence on health. However, research is scarce regarding how people with mental health problems experience EAT and if it influences occupational engagement. Eleven people with mental health problems were interviewed regarding this issue. Data was analyzed using a hermeneutic phenomenological approach. Results showed that EAT had a positive influence on

Implementing clinical guidelines for co-occurring substance use and major mental disorders in Swedish forensic psychiatry : An exploratory, qualitative interview study with mental health care staff
Introduction: Patients with substance use disorders (SUD) and co-occurring mental disorders (COD) within forensic psychiatric care often suffer poor treatment outcomes and high rates of criminal recidivism, substance use, and psychiatric problems. This study aimed to describe the conditions for, and mental health care staff's experiences with, implementing integrated SUD-focused clinical guideline
TOI-2046b, TOI-1181b, and TOI-1516b, three new hot Jupiters from TESS : planets orbiting a young star, a subgiant, and a normal star
We present the confirmation and characterization of three hot Jupiters, TOI-1181b, TOI-1516b, and TOI-2046b, discovered by the TESS space mission. The reported hot Jupiters have orbital periods between 1.4 and 2.05 d. The masses of the three planets are 1.18 ± 0.14 MJ, 3.16 ± 0.12 MJ, and 2.30 ± 0.28 MJ, for TOI-1181b, TOI-1516b, and TOI-2046b, respectively. The stellar host of TOI-1181b is a F9IV
Social Learning : Towards Sustainable Waste Management in Tongatapu
In the debate on sustainability many scholars are advocating for wider use of social learning models in order to successfully address complex challenges. Waste management is one example of complexity that our societies need to deal with and that increasingly calls for a broader approach, rather than focusing on narrow technical solutions only. This chapter is part of a broader study of limitations
Evaluation and control of inventory distribution systems with quantity based shipment consolidation
Joint consideration of inventory and shipment decisions is an important aspect of obtaining economically and environmentally sustainable distribution systems. We consider this issue in the context of a one-warehouse-multiple-retailer inventory system with quantity-based shipment consolidation to groups of nonidentical retailers facing Poisson demand. The system is centralized, with free informatio
