The reduction of greenhouse gas emission and the effort of carbon neutrality require the improvement of spark-ignition (SI) engines in terms of efficiency and capability to operate on renewable fuels. The electrode wear of spark plugs, used for ignition of novel fuels and lean mixtures, emerges as a significant challenge in this transition. Understanding the physical mechanism and influence from s
Particles larger than 10 nm from engine exhaust are gaining global concerns. In light of this, to investigate how EGR affects gasoline vehicle SPN10 (solid particles larger than 10 nm) emissions, seven gasoline vehicles (hybrid or conventional) were studied experimentally. The results revealed that EGR vehicles risk failing the current limit (6 * 1011 #/km) more than those without EGR if the cut-o
This article analyses infant and child sex ratios in late Imperial Russia relying on district-level information obtained from the 1897 Russian census (489 districts). The article shows that child sex ratios were, on average, relatively low (around 98 boys per hundred girls) due to the biological female advantage: the extremely high infant and child mortality rates took a greater toll on boys and p
Popular Abstract in Swedish Syftet med min avhandling har varit att visa på några viktiga drag som framträder vid en undersökning och en jämförelse av fyra etablerade poeter från 1970-talets diktargeneration i Grekland: Michalis Ganas, Maria Kirtzaki, Tzeni Mastoraki och Kostas Papageorgiou. Genom att deras litterära skapande satts i en tydlig relief mot relevanta politiska, historiska och samhäll
The envelope process is a useful analytical tool which is often used to study wave groups. Most research on statistical properties of the envelope, and thus of wave groups, was focused on one dimensional records. However for the marine application, an appropriate concept should be two dimensional in space and variable int time. Although a generalization to higher dimensions was introduced by Adler
The SIRPα-CD47 axis plays an important role in T cell recruitment to sites of immune reaction and inflammation but its role in T cell antigen priming is incompletely understood. Employing OTII TCR transgenic mice bred to Cd47-/- (Cd47KO) or SKI mice, a knock-in transgenic animal expressing non-signaling cytoplasmic-truncated SIRPα, we investigated how the SIRPα-CD47 axis contributes to antigen pri
Objective: Emergency complex abdominal aortic diseases are challenging to treat. During in situ laser fenestration (ISLF), aortic branches are covered and flow is restored by in situ fenestration of the stent graft, with promising midterm results. This study aimed to expand on the limited body of knowledge of midterm outcomes of ISLF in renovisceral aortic pathology in a multicentre setting. Metho
Syftet med denna studie var att undersöka om en likabehandlings workshop kunde minska deltagares fördomsfullhet samt öka deras perspektivtagande, psykologiska flexibilitet, medkänsla och värdegrundsförankring. Detta jämfört med en föreläsningskontroll som bestod av information om fördomar, diskriminering och mångfald. Studien ämnade även utröna om kopplingar mellan social dominansorientering (SDO)The purpose of present study was to examine if an equal treatment workshop would lessen prejudice and increase perspective taking, psychological flexibility, compassion, and connectedness to one’s values. The control group received a lecture with information regarding prejudice, discrimination, and diversity in the workplace. The study also examined whether there was a relation between Social Domi
Bird flight behaviors have been an interesting topic for many years, among which researchers have focused mostly on detailed aerodynamics of flight and more general aspects such as migration strategies. The recent development of accelerometers which could be easily attached to animals has speeded up the investigation of animal movements. Different behaviors could be categorized, and energy consump
Mixed support regarding firm capital structure reaction to the Tax Cut and Jobs Act is found. In the main difference-in-differences estimation, support is found for the predictions of trade-off theory after the inclusion of control variables aiming to capture shareholder distribution and capital structure optimization. These results do not prove robust to a more granular matching procedure. A uniq
Build more, build better, and build faster are concepts that more and more people become aware of. Can Construction Management (CM) achieve the right price and quality in a time and cost-effective way? Construction Management is a form of a project delivery method that may occur under different types of construction contracts. The purpose of this survey is to identify the strengths and weaknesses
The objective of this study was to analyze parent’s experiences on multisystemic therapy after their juvenile had completed their treatment. As MST is a family-oriented intervention, we wanted to research the parent’s experiences of the method since they have a significant role in their youth’s lives. The study was conducted through qualitative semi-structured interviews with five parents in a joi
