Enzymatic treatment of hemicelluloses and lignin isolated from thermomechanical pulp mill process water

Hemicelluloses dissolved in thermomechanical pulp (TMP) mill process streams can be used to manufacture high-value-added products. The molecular mass of the dissolved hemicelluloses is about 10 kDa. In some applications, it would be beneficial with larger molecules. It was therefore investigated whether it is possible to increase the size of hemicelluloses isolated by microfiltration and ultrafilt

Changing landscapes, climate and biodiversity as seen through art.

Landscape paintings from the last twocenturies can be used in certain cases as an aid forstudies of changes in land use. Also changes in biodiversitycan be evaluated in comparison with thepresent situation. Similarly, effects of global warmingin older paintings can also probably be evaluated.Examples of paintings from Sweden done by BrunoLiljefors and from the United States done by severalpainters

Individual Face-to-Face Cognitive Behavioural Therapy in Multiple Sclerosis : A Qualitative Study

OBJECTIVE: To investigate how people with multiple sclerosis (MS) experience their participation in individual, face-to-face cognitive behavioural therapy (CBT) aimed at alleviating depressive symptoms.METHOD: Semistructured interviews with 12 participants were conducted after CBT and analyzed using qualitative content analysis.RESULTS: Two main themes emerged: CBT as a demanding process and confr

Svåra samtal -vetenskap och läkekonst

Syftet med denna masteruppsats var att få fördjupad förståelse för svåra samtal som läkare upplever och beskriver dem. Djupintervjuer med öppna frågor genomfördes med 10 yrkesverksamma läkare med erfarenhet av svåra samtal med patienter och närstående och som hade anmält sig för att delta i kursen ”De nödvändiga samtalen”. Materialet analyserades med tematisk analys. Totalt identifierades nio temaThe aim of this master dissertation was to gain a deeper understanding of the breaking of bad news through narration of the lived experiences of doctors. In-depth interviews using open questions were conducted with ten professionally active medical doctors who had 1) experience of breaking bad news and 2) applied to participate in a communications course. The data was analyzed using thematic analy

Prospective validation of two mathematical models to calculate the risk of endometrial malignancy in patients with postmenopausal bleeding and sonographic endometrial thickness ≥4.5 mm

AIM: To prospectively validate two mathematical models for calculating the likelihood of endometrial malignancy in patients with postmenopausal bleeding (PMPB), sonographic endometrial thickness (ET) ≥4.5 mm and no fluid in the uterine cavity.METHODS: This is a prospective observational diagnostic validation study performed in a PMPB clinic in a university hospital. Of 860 consecutive patients, 35

Hybrid organic-inorganic systems formed by self-assembled gold nanoparticles in CuPcF4 molecular crystal

In this work we have fabricated and studied hybrid organic-inorganic nanocomposite system formed by gold nanoparticles self-assembled in organic semiconductor thin film - copper tetrafluorophthalocyanine (CuPcF4). By means of Photoelectron Spectroscopy and Transmission Electron Microscopy (TEM) the evolution of the morphology and electronic structure of the system as a function of nominal gold con

Framework for non-coherent interface models at finite displacement jumps and finite strains

This paper deals with a novel constitutive framework suitable for non-coherent interfaces, such as cracks, undergoing large deformations in a geometrically exact setting. For this type of interface, the displacement field shows a jump across the interface. Within the engineering community, so-called cohesive zone models are frequently applied in order to describe non-coherent interfaces. However,

Adaptive use of information during growth can explain long-term effects of early life experiences

Development is a continuous process during which individuals gain information about their environment and adjust their phenotype accordingly. In many natural systems, individuals are particularly sensitive to early life experiences, even in the absence of later constraints on plasticity. Recent models have highlighted how the adaptive use of information can explain age-dependent plasticity. These

Climatic conditions inside nuclear reactor containments : Evaluation of moisture condition in the concrete within reactor containments and interaction with the ambient compartments

Inom kärnkraftsindustrin är säkerhet den aspekt som prioriteras högst. Alla kärnkraftverk är designade för att i högsta möjliga mån förhindra läckage av radioaktivetet till omgivningen, både under drift och i händelse av en allvarlig olycka. Med anledning av detta är reaktorinneslutningens vägg en av de viktigaste säkerhetsrelaterade konstruktionerna vid en anläggning, detta då denna konstruktionsSafety is the top priority at a nuclear facility. The nuclear power plants are designed to prevent radioactive leakage to the surroundings, both during normal operation as well as in case of a severe accident. One of the most important structures in a nuclear power plant, with regard to safety, is thus the reactor containment wall. The containment wall is the last main barrier to prevent radioacti

Polymorphisms within base and nucleotide excision repair pathways and risk of differentiated thyroid carcinoma

The thyrocytes are exposed to high levels of oxidative stress which could induce DNA damages. Base excision repair (BER) is one of the principal mechanisms of defense against oxidative DNA damage, however recent evidences suggest that also nucleotide excision repair (NER) could be involved. The aim of present work was to identify novel differentiated thyroid cancer (DTC) risk variants in BER and N

An Object-Oriented Regression for Building Disease Predictive Models with Multiallelic HLA Genes

Recent genome-wide association studies confirm that human leukocyte antigen (HLA) genes have the strongest associations with several autoimmune diseases, including type 1 diabetes (T1D), providing an impetus to reduce this genetic association to practice through an HLA-based disease predictive model. However, conventional model-building methods tend to be suboptimal when predictors are highly poly
