Lignin accounts for 15 – 30 % of plant biomass, but is till today remarkably underutilized, mainly due to its heterogeneity and recalcitrance towards depolymerization. The bacterial conversion of lignin into value added chemicals is a highly promising approach to overcome this underutilization and can help to improve the economic competitiveness of the biorefinery concept. In the current study, 1
Applications based on Wireless Sensor Networks are making their way into all kinds of industries. Today, they can do anything from off-loading hospitals by monitoring patients in their homes to regulating production lines in factories. More often than not, they perform some kind of surveillance and tracking. Thus, in most cases the information they carry is sensitive, rendering good encryption sch
Being stateless, roughly means being without a citizenship of any nation. This is the definition of being stateless in legal terms, called de jure statelessness. There is also statelessness that entails being without the efficient protection of one’s nation, called de facto statelessness. Two groups of stateless migrants that correspond to these definitions are Bidoons from Kuwait and Palestinians
Förekomsten av tekniska standarder är fundamental för den tekniska utvecklingen och medför flera konkurrensfördelar. Standardisering kan emellertid riskera att vara konkurrenshämmande i samband med patentinnehavares användning av de rättsmedel som står till deras förfogande. Så är fallet när patenterad teknik implementeras i standarder och får status som standardessentiella patent. I utbyte mot deThe presence of technical standards is fundamental to the technical development and entails several competitive advantages. Standardization may, however, risk being anticompetitive in relation to patent holders’ use of legal remedies available to them. This is the case when patented technology is implemented in standards and is given the status as standard essential patent. In exchange for the pos
Introduction: Data on outcome in persons with haemophilia B (PwHB) are limited and mainly extrapolated from studies of haemophilia A (HA). Aim: To characterize treatment outcomes in persons with severe HB in the Nordic region, with a focus on joint health, compared with matched controls with HA. Methods: PwHB attending haemophilia centres in Denmark, Finland, Norway and Sweden were enrolled and ma
Popular Abstract in Swedish Arbetet i denna avhandling presenteras i 6 olika delarbeten (artiklar I-VI). Artiklarna I-III behandlar två olika enzymer som bryter ner cyklodextriner, vilka är ringformade molekyler med samma beståndsdelar som i stärkelse (dvs sammanlänkade glukosmolekyler). Dessa s.k. cyklodextrinaser kommer ursprungligen från två bakterier som har isolerats i varma källor på Island.Two putative cyclodextrinases (CDases) were amplified from two moderate thermophiles isolated in Iceland: Anoxybacillus flavithermus and Laceyella sacchari. They were cloned, expressed and characterized. The expression of the former was optimized in E. coli by using a solubility-enhancing tag, NusA, and tuning of inducer concentration in the expression strain Tuner(DE3). The CDases were optimally
Traditional basal-bolus and closed-loop artificial pancreas therapy for type 1 diabetes mellitus were studied in the present work and novel insulin delivery profiles have been identified. Type 1 diabetes is a chronic condition resulting from autoimmune destruction of the pancreatic insulin producing β-cells. Inadequate insulin secretion prevents efficient glucose metabolism and is a serious health
Background: Problem gambling is a public health issue affecting both the gamblers, their families, their employers, and society as a whole. Recent law changes in Sweden oblige local and regional health authorities to invest more in prevention and treatment of problem gambling. The economic consequences of gambling, and thereby the potential economic consequences of policy changes in the area, are
Human prostate specific antigen, PSA, is a product of the human glandular kallikrein gene locus on chromosome 19 that is almost selectively expressed by prostate tissue. PSA is one of the dominating prostate derived proteins in seminal fluid. The mature form of PSA, a single chain glycoprotein of 237 amino acids, is a serine protease manifesting restricted chymotrypsin-like activity. PSA is mainly
With the emergence of Alzheimer's disease (AD) disease-modifying therapies, identifying patients who could benefit from these treatments becomes critical. We evaluated whether a precise blood test could perform as well as established cerebrospinal fluid (CSF) tests in detecting amyloid-β (Aβ) plaques and tau tangles. Plasma %p-tau217 (ratio of phosporylated-tau217 to non-phosphorylated tau) was an
Humanity’s ever-growing energy demands require the implementation of more sustainable ways to harvest and store energy. At the same time, the reduction of greenhouse gas emission and thus global warming remains of paramount importance. To this end, solar energy harvesting presents an attractive route towards satisfying these requirements—be that by conversion to thermal energy, electricity or to c
Background: [18F]flutemetamol PET scanning provides information on brain amyloid load and has been approved for routine clinical use based upon visual interpretation as either negative (equating to none or sparse amyloid plaques) or amyloid positive (equating to moderate or frequent plaques). Quantitation is however fundamental to the practice of nuclear medicine and hence can be used to supplemen
Background: Research has indicated that interactive, computerized case simulations using immersive virtual reality (VR) technology may be beneficial in the augmentation of conventional methods of assessment and treatment in forensic psychiatry, primarily through providing an engaging and safe environment in which the user can practice and learn skills and behaviors. However, there does not appear
As rotary machines have become more complicated, balancing processes have been classified as a vital step in condition monitoring to ensure that machines operate reliably, smoothly and safely. All rotating objects will deflect during rotation and all objects possess certain natural frequencies in the absence of rotation. However, an unbalanced object can cause significant unwanted deflection creat
For the past 30 to 40 years, well before the concept of sustainable development became politically correct, regulation of the environment has been covered by Environmental Protection Agencies worldwide. Perhaps one of the most important things that we have learned is that regulations have significant costs, not just benefits, and that analysis of the cost and benefit of proposed rules is an indisp
Due to the large-scale production of lignin, continuous flow reactors are preferred for its further valorization through depolymerization. However, there is limited literature on their use in lignin depolymerization, especially concerning feedstock pretreatments and catalyst deactivation. Therefore, in this study, the impact of a batch solvolysis pretreatment on the mild reductive catalytic depoly
Background: Mental distress is a major public health problem which includes anxiety, depression and somatic symptoms such as sleeping problems, fatigue and headache. University students are consistently reported to have higher levels of mental distress compared to the general population. Although university students with mental distress have significantly impaired cognitive functioning, learning d
