Background. To further improve the outcome of clinical islet transplantation analysis of the impact of donor- and process-related factors could be of great importance. Materials and Methods. Thirty-eight consecutive clinical islet transplantations were performed with consecutive islet isolations. Univariate analysis for donor- and isolation-related variables were correlated with recipient C-peptid
The move towards fire performance-based design in building and transport regulations has led to an increased use of fire models. This increased use of these models and the evolution of different regulations have put higher demands on the predictive capability of fire models. The purpose of this paper is to give an overview of different activities relating to the validation and verification of comp
Ethnography has become something of a buzzword in recent years. It is talked about and invoked in disciplines ranging from anthropology and ethnology to literature, history, business administration and design studies. Textbooks that teach ethnography tend to imbue students with the impression that ethnography is a mode of systematic investigation by which the researcher gets closer to the realitie
Many small companies ask themselves how and when to begin participating in the information revolution, and what changes this may bring to their business operation. Five typical models of product data integration were designed to help users to create a comprehensive view of the problems of technical information systems in companies. It was found that setting up an information system is a dynamic pr
In this study, multilayered Cu mesh/AZ31 Mg foil composites were designed and fabricated by diffusion bonding in a closed graphite mold at 400–445 °C. The effects of temperature on the microstructure of the joints formed and the thermal conductivity of the composite was evaluated. The mechanism responsible for the observed improvement in thermal conductivity was analyzed. After diffusion bonding,
In this paper, two distinct polymer electrolyte fuel cell stack models are constructed: a detailed numerical model (DNM) employing a fine-scale computational mesh and a coarse-mesh approach based on a distributed resistance analogy (DRA) where diffusion terms in the transport equations are replaced by rate terms. Both methods are applied to a 5-cell, high-temperature polymer electrolyte fuel cell
Realization of robust coherent quantum phase slips represents a significant experimental challenge. Here we propose a design consisting of multiple nanowire junctions to realize a phase-slip flux qubit. It admits good tunability provided by gate voltages applied on superconducting islands separating nanowire junctions. In addition, the gates and junctions can be identical to or distinct from each
Abstract Abiotic environmental factors play a fundamental role in determining the distribution, abundance, and adaptive diversification of species. Empowered by new technologies enabling rapid and increasingly accurate examination of genomic variation in populations, researchers may gain new insights into the genomic background of adaptive radiation and stress resistance. We investigated genomic v
Both numerical simulations and experiments were conducted in a heavy-duty DICI engine, with PRF81 as a gasoline surrogate, to investigate how the fuel stratification, auto-ignition and combustion are affected by the start of injection (SOI). The intake air temperature was adjusted to keep the combustion phasing constant when the SOI was swept from −100 to −20 oCA ATDC, covering different regimes o
Objective: To study the difference in incidence and risk of fragility fractures between rheumatoid arthritis (RA) patients followed up early in the disease and the general population in Sweden; and the fracture risk changes in RA patients diagnosed in the 1990s and 2000s because of earlier, more potent pharmacological treatment in the later period. Method: Patients with early RA were recruited fro
To achieve a reduced chemical model for comprehensive prediction of ammonia/hydrogen/methane mixture combustion, a detailed chemical mechanism with 128 species and 957 reactions was first assembled using models from literature. Directed relation graph with error propagation (DRGEP) with sensitivity analysis reduction method was then used to obtain compact reaction models. The studied reduction con
This chapter presents a case study of how Accus, a small Swedish company, worked on developing a circular business model for light sign production and installation to become more sustainable. Drawing on Actor Network Theory (ANT), the Accus case shows that circular business model development is a cooperative endeavor that rests on bringing together a large and changing array of human, as well as n
In the last 15 years we have seen, as a response to power and thermal limits for current chip technologies, an explosion in the use of multiple and even many computer cores on a single chip. But now, to further improve performance and energy efficiency, when there are potentially hundreds of computing cores on a chip, we see a need for a specialization of individual cores and the development of he
Huntington disease (HD) is a hereditary neurodegenerative disorder caused by an expanded cytosine–adenine–guanine triplet repeat in the huntingtin gene. The current diagnosis is based on the presence of typical motor signs in combination with a positive gene test. The motor onset of the disease is usually between 30 and 50 years of age, and the disease then progresses over around 20 more years. No
Övergången till en hållbar textilindustri, såsom textilåtervinning, kräver förbättrade metoder för hantering av färgämnen. För närvarande finns inga generella, industriellt implementerade processer som avlägsnar färgämnen utan att skada dem, och examensarbetet undersöker detta tillsammans med Rewin Textiles AB. Företaget återvinner polyester genom depolymerisering och därför utvärderas implementerThe transition towards sustainable textile approaches, such as textile recycling, requires im-proved methods for handling dyes. Currently, no real industrially implemented processes exist that remove dyes without damaging them and this thesis investigates this issue together with Rewin Textiles AB. This company recycles polyester through depolymerisation and therefore, the implementation of a pre-
Studier visar på att det finns bristfällig forskning om arbetsterapeuters arbete med sexuell hälsa. Syftet: Att undersöka arbetsterapeuters arbete med sexuell hälsa hos individer med intellektuell funktionsnedsättning inom daglig verksamhet och vuxenhabilitering. Metod: Kvantitativ enkätstudie där 30 stycken arbetsterapeuter rekryterades via icke-slumpmässigt bekvämlighetsurval och snöbollsurval. Studies show that there is insufficient research on occupational therapists (OT) work on sexual health. Purpose: Investigate OT’s work on sexual health with individuals with intellectual disabilities in day-centres and adult habilitation. Method: A quantitative survey study where 30 OT’s were recruited via nonrandom convenience selection and snowball selection. Quantitative data were analyzed with
The 4th Industrial Revolution provides a window of opportunity for the developing world and in particular, Sub-Saharan Africa to catch-up in terms of social and economic development by enhancing growth through technological advances. At the same time, it bears the risk for Sub-Saharan Africa to fall even further behind if technological advances cannot be absorbed into the region’s economies. Altho
At Tetra Pak, general knowledge of food and beverage processing is of great importance. This in turn, depends on the equipment used for the particular process. One of these equipment consists of deformed tubes made of stainless steel 316L. The aim of the present work is to get an understanding of the material 316L. To achieve this, physical tensile tests are performed to study the material behavio
During protoplanetary disk formation, dust grains located in the outer disk retain their pristine icy composition, while solids in the inner stellar-heated disk undergo volatile loss. This process may have left a fossil record in Solar System material, showing different nucleosynthetic imprints that have been attributed to different degrees of thermal processing. However, it remains unclear how a
Coacervates of oppositely charged milk proteins are used in functional food development, mainly to encapsulate bioactives. To uncover the driving forces behind coacervates formation, we study the association of lactoferrin and β−lactoglobulin at amino-acid level detail, using molecular simulations. Our findings show that inter-protein electrostatic interactions dominate and are, surprisingly, equa
