The low-temperature combustion (LTC) is an attractive concept that enables the modem combustion engines to move toward sustainability mainly by increasing the efficiency and decreasing the emissions. The modern combustion engines which are working based on the LTC concept have specific fuel requirements. Fuel ϕ-sensitivity is a key factor to be considered for tailoring fuels for these engines. Fue
Xerostomi, är en kliniskdiagnos för muntorrhet. Muntorrheten kan uppkomma till följd av åldersförändringar, strålnings- och kemikalieexponering eller en inflammation i spottkörtlarna. Extracellulära vesiklar (EVs) är små vesiklar (i nanometerstorlek) vilka normalt används vid cellers kommunikation med varandra. EVs har visats ha positiv effekt i djurförsök vid skada eller sjukdom i tex lunga, hjärXerostomia (dry mouth symptoms) is a group of incurable debilitating conditions of salivary glands caused by aging, radiation/chemical exposure, or aberrant inflammation in the salivary glands. During this PhD thesis, we aimed to evaluate whether cell-derived strategies (e.g., extracellular vesicles, EVs) could be a potential new therapy to ameliorate salivary gland injury and restore function aft
Context: Effective industry-academia collaboration may increase software engineering research relevance by increased realism, yet very challenging for reasons like confidentiality concerns, different objectives and priorities. Objective: We analyse industry-academia collaboration scenarios based on our own experiences as Ph.D. student and supervisor, and provide insights and recommendations to fac
En del av de personer som fått avslag på sin ansökan om asyl kan inte återvända. Med hårdare regler som nu föreslås, riskerar Sverige och Europa få en grupp papperslösa som hamnar i en helt utblottad situation utan några möjligheter till en framtid. Det skriver professor Anna Lundberg, tidigare särskild utredare för regeringen.
The World Energy Council ranks the Danish energy system among best in the world judging by the energy trilemma criteria: energy security, energy equity, and sustainability. District heating (DH) and CHPs are pivotal for this ranking. This brief historical account illustrates how a mix of historical events, collective societal experiences, cultural and political values inform the Danish history of
Sedan Polismyndigheten 2015 publicerade den första listan över socialt utsatta områden i svenska städer har problematiken där fått mycket uppmärksamhet i den politiska samhällsdebatten, i media och i forskning. På kommunal och nationell nivå diskuteras orsaker och möjliga lösningar rörande dåliga levnadsförhållanden, parallella maktstrukturer, kriminalitet
Nitrate pollution in groundwater is a severe problem in Shimabara Peninsula, Nagasaki Prefecture, Japan. Previous studies have investigated water quality characteristics in the northern part of the peninsula and shown serious effects of nitrate pollution in the groundwater. The present study aimed to investigate the groundwater quality in the southern areas of the peninsula for improved understand
Even if there is evidence of play from all vertebrate classes suggesting origins in deep time, descriptions of the evolution of play are surprisingly patchy. To bridge this gap, one must study play comparatively and include taxa from key phylogenetic positions. This study is the first systematic description of play in greater rheas, and thereby the first such report on any palaeognath bird. Palaeo
Aquatic organisms are constantly at risk of being exposed to potentially harmful chemical compounds of natural or anthropogenic origin. Biological life can for instance respond to chemical stressors by changes in gene expression, and thus, certain gene transcripts can potentially function as biomarkers, i.e. early warnings, of toxicity and chemical stress.

This article presents and discusses the case study “Scraping the surface,” aworkshop about sustainable design held for master’s students of different design majors at the FHNW Academy of Art and Design. Through marketing we, as consumers, are bombarded with products claiming to be sustainable. As a result, sustainability has become a buzz word. “Scraping the surface” highlighted the complex factor
The objective was to investigate the validity and reliability of a new instrument assessing sexual harassment at a public university in Sweden. In-depth interviews and focus group discussions resulted in a 10-item instrument, the ‘Lund University Sexual Harassment Inventory’ (LUSHI). A survey was sent to all staff, including PhD students, and students, with a response rate of 33% (n = 2736) and 32
MHC genes play a fundamental role in immune recognition of pathogens and parasites. Therefore, females may increase offspring heterozygosity and genetic diversity by selecting males with genetically compatible or heterozygous MHC. In birds, several studies suggest that MHC genes play a role in mate choice, and recent evidence suggests that olfaction may play a role in the MHC-II discrimination. Ho
We introduce the concept of a k-dimensional matrix product D of k matrices (Formula presented.) of sizes (Formula presented.) respectively, where (Formula presented.) is equal to (Formula presented.). We provide upper bounds on the time complexity of computing the product and solving related problems of computing witnesses and maximum witnesses of the Boolean version of the product in terms of the
Various concepts guide discussions on global literature, not least ›transnational‹. The presenttext advocates, however, for the term trans-imperial, as offering a more correct definitionof world literature, or global literature, both in pre-modern and modern times. Imperialspheres build up worlds of strong interconnections, and the languages they employ becomeprivileged languages that may last bey
