Laccase catalysed oxidation of syringyl and guaiacyl subunits of lignin and their modification with an aromatic amine, p-aminobenzoic acid (PABA) were investigated. Laccase from Galerina sp. HC1 isolated earlier by us was used as the main catalyst, and Trametes versicolor laccase was used for comparison. Among the syringyl compounds, syringic acid and syringaldehyde were oxidised to 2,6-dimethoxy-

Tetra Pak® is a world leading food packaging company with a large variety of paperboard beverage packages. In the development of paperboard packages, an essential component is utilizing simulation models long before physical prototypes are manufactured. This speeds up the development process and allows quick evaluation of new designs. For this to be an effective approach, confidence in the virtual
Konceptet personalisering innebär att fokus allt oftare riktas mot individuella politiker och deras personliga egenskaper. Sociala medier, så som Instagram, har gjort konceptet än mer aktuellt då möjligheterna att politiskt kommunicera personligt har ökat genom dessa. Studien ämnade att undersöka om personaliserad kommunikation av framstående svenska politiker på Instagram har ökat under den senasPersonalisation is a concept which is based on the idea that focus is increasingly directed at the individual politician and his or her personal characteristics. Social media, such as Instagram, has revived the concept since the possibilities for personalised political communication have increased. This study aimed to examine if personalised communication among prominent Swedish politicians on Ins
Föreställ dig att inga fler människor ska behöva dö av cancer. Det låter som en utopi, men med hjälp av ny teknik kommer diagnosticering och behandling av cancer att förbättras avsevärt och fler människor kunna hjälpas. Redan nu klarar maskininlärning av att diagnostisera bröstcancer med större träffsäkerhet än vad erfarna radiologer kan. Det är inte bara bröstcancervården som kommer kunna dra nytDue to the increasing incidence rates of skin cancer, there is an urgent need for novel technologies that can improve diagnostic accuracy and patient outlook. In a previous study, a machine learning model was developed to automatically delineate skin tumours from non-invasive hyperspectral images. However, the reliability of the model was undermined by difficulties with a preprocessing step in whi
Purpose: To examine how intellectual property rights holders and intellectual property rights experts view the phenomenon of characters’ copyright expirations. Research questions: How can intellectual property rights holders cope with the expiration of their characters’ copyright? What are the possible implications of copyright expiration for brands? Methodology: The study utilizes an inductive,
Balance functions have been regarded in the past as a method of investigating the late-stage hadronization found in the presence of a strongly-coupled medium. They are also used to constrain mechanisms of particle production in large and small collision systems. Charge balance functions for inclusive and identified particle pairs are reported as a function of charged particle multiplicity in proto
Provupparbetning är ett viktigt steg i många metoder för kemisk analys.Detta gäller framförallt fasta prover då de kemiska ämnena som avses för analys, även kallade analyter, måste extraheras ut. Det vill säga att genomföra en överföring av analyter från provet till ett lösningsmedel. Därefter kan halten bestämmas med de metoder som ofta finns till hands i ett analyslaboratorium. I de fall då fettSupercritical fluid extraction is an extraction technique suitable for lipophilic compounds from solid samples. Most commonly supercritical carbon dioxide is the main component in the extraction phase, rendering the technique relatively environmentally benign. The extraction technique is rapid due to the low viscosity and the high diffusivity of analytes in the supercritical extraction phase.The s
Objectives: To evaluate the potential of artificial intelligence (AI) to identify normal mammograms in a screening population. Methods: In this retrospective study, 9581 double-read mammography screening exams including 68 screen-detected cancers and 187 false positives, a subcohort of the prospective population-based Malmö Breast Tomosynthesis Screening Trial, were analysed with a deep learning–b
Today, every new building is constructed with the ambition of it having a very low energy demand or even being completely neutral with regard to supply and demand over a year. In modern low energy or nearly zero energy residential buildings like these, the behaviour of the occupants becomes increasingly more significant in terms of the energy performance of the building. Occupants who are present
Interleukin (IL)-1 family cytokines potently regulate inflammation, with the majority of the IL-1 family proteins being secreted from immune cells via unconventional pathways. In many cases, secretion of IL-1 cytokines appears to be closely coupled to cell death, yet the secretory mechanisms involved remain poorly understood. Here, we studied the secretion of the three best-characterized members o
This contribution seeks to demonstrate how recently developed 3D GIS platforms can help archeologists in relating to the original context legacy data that can be employed to digitally reconstruct the sequence of arbitrary layers as it was observed and then excavated in the end of the nineteenth century. This research has been conducted on the prehistoric cave of Stora Förvar, located on the small
We discuss γ∗γ∗ → ηc(1S), ηc(2S) transition form factors for both virtual photons. The general formula is given. We use different models for the cc¯ wave function obtained from the solution of the Schrödinger equation for different cc¯ potentials: harmonic oscillator, Cornell, logarithmic, power-law, Coulomb and Buchmüller-Tye. We showed some examples of wave functions in the Light Front represent
Purpose: To investigate how an artificial intelligence (AI) system performs at digital mammography (DM) from a screening population with ground truth defined by digital breast tomosynthesis (DBT), and whether AI could detect breast cancers at DM that had originally only been detected at DBT. Materials and Methods: In this secondary analysis of data from a prospective study, DM examinations from 14
Soil is likely the most complex ecosystem on earth. Despite the global importance and extraordinary diversity of soils, they have been notoriously challenging to study. We show how pioneering microfluidic techniques provide new ways of studying soil microbial ecology by allowing simulation and manipulation of chemical conditions and physical structures at the microscale in soil model habitats.The
Aims Pancreatic β-cells synthesize and release serotonin (5 hydroxytryptamine, 5HT); however, the role of 5HT receptors on glucose stimulated insulin secretion (GSIS) and the mechanisms mediating this function is not fully understood. The aims of this study were to determine the expression profile of 5HT receptors in murine MIN6 β-cells and to examine the effects of pharmacological activation of 5
When new buildings are constructed the indoor climate for the first period may differ from the one after some years due to various factors, for example may the emissions from the building materials be higher, possibly affecting the air quality, and the balancing of the technical systems; the mechanical supply and exhaust system and heating may not be completely finished. The perceived indoor clima

A 54-year-old male with colorectal cancer was treated with cytoreductive surgery (CRS) in combination with hyperthermic intraperitoneal chemotherapy (HIPEC) because of peritoneal carcinomatosis. A left hemicolectomy was performed with creation of a colostomy and closure of rectal stump and two more small bowel resections. Postoperative course was complicated by anastomotic leakage, following two r
The present dissertation concerns typologically unusual ways of encoding manner information, namely verbal affixes (manner affixes), incorporated constituents (incorporated manner modifiers) and auxiliary verbs (manner adverbial verbs). A key proposal is that all three are overt realizations of syntactic heads merged in the clausal spine, thereby presenting novel data that can be used to probe int
