Road haulage operations in general, and distribution in particular, are inefficient. Given the societal importance of road haulage and the low efficiency of the sector, road hauliers need to improve their operations and systematically tackle inefficiencies. However, the real causes of these inefficiencies, the “root causes”, have not been sufficiently examined in previous studies.

Projektet HITS/Transparens utforskar hur frivillig användning av informations- och kommunikationsteknologi av privata aktörer kan förbättra informationstransparens i transport av farligt gods. Detta tillvägagångssätt skiljer sig från en lång rad projekt som sedan 80-talet haft ett centralt myndighetsperspektiv på informationshantering kring farligt gods. I linje med tidigare resultat inom forsknin

Species with similar resource requirements are commonly assumed to competitively exclude each other, unless they differentiate their ecological niches. Hence, parasitoid wasps that use the same host species need to find some way to avoid competition. The aim of this study was to identify the role of volatile cues from oilseed rape plants and the larval host in niche separation between three coexis

The amphibian fauna of the Central Menabe region in Western Madagascar is important in respect to their extraordinary adaptations to the dry forest habitat. This habitat is highly threatened. Until 1990, the dry forest in the west of the island was thought to have been reduced to only 3% of its original extent. New analyses show that this deforestation was ongoing at an alarming rate also in the l

This thesis investigates the coupling between moisture, heat, and deformation in paperboard. The presented investigations are primarily conducted via macroscale continuum modeling but experimental characterisations are also made. The continuum modeling is presented in a mixture theory framework where the paperboard is considered as a porous media composed of three immiscible phases; a network of c

Objectives. The Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) is a collaborative effort of Nordic cardiac surgery centers to study acute type A aortic dissection (ATAAD). Here, we outline the overall objectives and the design of NORCAAD. Design. NORCAAD currently consists of eight centers in Denmark, Finland, Iceland and Sweden. Data was collected for patients undergoing surgery f

Objective: To investigate the influence of cardiovascular risk factors, including fasting plasma glucose (FPG), on the association between electrocardiographic (ECG) and echocardiographic left ventricular hypertrophy (LVH) in an elderly population. Methods: We tested cross-sectional associations between electrocardiographic and echocardiographic LVH, defining LVH according to the Sokolow-Lyon volt

A chemically defined diet is a useful tool for the study of nutritional physiology of organisms. We have developed such a diet for Camponotus carpenter ants to facilitate experiments on nutritional requirements of these ants. Worker colonies of Camponotus floridanus were fed with a chemically defined diet, containing all essential minerals, amino acids, vitamins, growth factors and sucrose in an a

Optical measurement techniques have proven to be useful tools for studying combustion-related phenomenon. The fact that the techniques are optical facilitates performing the measurements without impinging upon the measurement object, such as the combustion event that can be involved. Such techniques can be species-specific and be performed in situ, i.e. in the setting in which the phenomena in que

Background: Carpenter ants (genus Camponotus) are considered to be omnivores. Nonetheless, the genome sequence of Blochmannia floridanus, the obligate intracellular endosymbiont of Camponotus floridanus, suggests a function in nutritional upgrading of host resources by the bacterium. Thus, thestrongly reduced genome of the endosymbiont retains genes for all subunits of a functional urease, as well

Background: Depending on the definitions used, between 5 and 20 % of all Swedish children grow up with at least one parent suffering from alcohol problems, while 6 % have at least one parent who has received inpatient psychiatric care, conditions that may affect the children negatively. Nine out of ten Swedish municipalities therefore provide support resources, but less than 2 % of these children

This paper aims to analyze whether patients should be allowed to veto research-related use of medical data collected during routine follow-ups after their withdrawal from first-in-human clinical trials. Forms of withdrawal are identified and it is argued that the right to withdraw might be limited to some of these. The paper concludes that if veto right is denied, then: the research participant sh

PurposeThe location of a logistics facility is strategic decision, impacting distribution cost, efficiency and environmental impact. The purpose of this paper is to systemize existing knowledge by a literature review. Based on the literature review we propose a framework in this area of theoretical and practical relevance.Design/methodology/approachWe have examined the peer-reviewed literature on
