Bio-based 5-hydroxymethylfurfural (HMF) serves as an important platform for several chemicals, among which 2,5-furan dicarboxylic acid (FDCA) has attracted considerable interest as a monomer for the production of polyethylene furanoate (PEF), a potential alternative for fossil-based polyethylene terephthalate (PET). This study is based on the HMF oxidizing activity shown by Mycobacterium sp. MS 16

BACKGROUND: Hair cosmetics such as hair dyes, bleaching, waving, and cleansing products are composed of numerous chemical ingredients. Allergic reactions to these contact allergens, other than p-phenylenediamine, are rarely reported.OBJECTIVES: To study the incidence of patch test reactions to hair cosmetic allergens and identify the factors associated with hair cosmetic allergy in Thailand.METHOD

The interaction of blood coagulation factor X and its Gla-containing fragments with negatively charged phospholipid membranes composed of 25 mol% phosphatidylserine (PtdSer) and 75 mol% phosphatidylcholine (PtdCho) was studied by surface plasmon resonance. The binding to 100 mol% PtdCho membranes was negligible. The calcium dependence in the membrane binding was evaluated for intact bovine factor

Accident prediction models are often used to predict the number of accidents on segments and at intersections in the road network. Most often the models are developed for a total number of crashes for the facility, or crashes by severity. However, the frequency and severity of crashes of different types can be expected to vary with regards to the underlying phenomena that cause them to occur. To b

Antigenic diversity in pathogenic microbes can be a result of at least three different processes: diversifying selection by acquired immunity, host–pathogen coevolution and/or host specialization. Here, we investigate whether host specialization drives diversity at ospC (which encodes an immunodominant surface protein) in the tick-transmitted bacterium Borrelia afzelii. We determined prevalence an

This thesis demonstrates the usefulness of sedimentary pigments as biomarkers of environmental change in estuarine systems and as biomarkers in lakes in relation to climate change. These are two fields where sediment pigment records as measured by high-performance liquid chromatography (HPLC) are emerging areas of study. A detailed study was undertaken to examine the effects of different storage o

Stability is a fundamental property affecting function, activity, and regulation of biomolecules. Stability changes are often found for mutated proteins involved in diseases. Stability predictors computationally predict protein-stability changes caused by mutations. We performed a systematic analysis of 11 online stability predictors' performances. These predictors are CUPSAT, Dmutant, FoldX, I-Mu

Feedbacks mechanisms are essential components of our climate system, as they either increase or decrease changes in climate-related quantities in the presence of external forcings. In this work, we provide the first quantitative estimate regarding the terrestrial climate feedback loop connecting the increasing atmospheric carbon dioxide concentration, changes in gross primary production (GPP) asso

Cykling är en viktig del av ett hållbart transportsystem. Det bidrar bl.a. till en bättre miljö och förbättrad folkhälsa. Syftet med arbetet är att undersöka vilka faktorer som kännetecknar en bra cykelstad, ur en infrastruktursynpunkt och vilka faktorer som kan leda till ökad cykling. I arbetet intervjuas representanter för kommunerna Lund, Malmö och Helsingborg om vilka infrastrukturella åtgärdeCycling is an important part of a sustainable transport system. It contributes among other things to a better environment and improved public health. The aim of this thesis is to investigate which factors characterize a good cycling city, from an infrastructural point of view, and which factors may lead to increased cycling. In the thesis, representatives of the municipalities of Lund, Malmö and H

Photomultiplier tube (PMT) nonlinearities relevant for single shot high-speed lifetime phosphor thermometry were investigated by simulating decay curves with a light emitting diode (LED) at repetition rates between 1 Hz and 10 kHz. The PMT gain, LED decay time, and background radiant flux were also varied to investigate their impact on the measured decay time error.

Natural products have until recently provided the only remedy for treatment of diseases. The development of modern chemistry in the last centuries has opened the door for tapping into the chemical diversity found in nature. Synthetic natural products, together with analogues, are an important piece in the puzzle towards curing many ailments. In this thesis, synthetic endeavors towards different bi

AbstractThis research aims to investigate and compare how computers work on five different workstation setups of multiple or large screens and viewing distances (27-inch and 49-inch at 70 or 90 cm viewing distance) affect muscular load in neck/shoulders, working postures, and perceived exertions of non-presbyopic participants.

BackgroundDespite the fact that eldercare services are organizationally part of social work in Sweden, the social work practice is disappearing and older people are expected to take the responsibility for their own well-being. In this context, they have to create their own sense of meaningfulness in their everyday life, despite being subject to social care services.Methods As part of a research prBackgroundDespite the fact that eldercare services are organizationally part of social work in Sweden, the social work practice is disappearing and older people are expected to take the responsibility for their own well-being.
