Popular Abstract in English During recent decades, significant changes in fertility pattern are seen in the Western World. Declining birth rates and smaller family sizes affect the population size, but also cause unwanted effects for the desired number of children to be achieved by the individual couple. Also involuntary childlessness is a consequence of postponing childbearing to an age where theDeclining birthrates and infertility are now a common problem in the Western World. Due to the tendency to postpone childbearing an increasing age of women who consider motherhood is generally seen. A factor closely related to female fertility is the ovarian reserve, a term used to designate both quantitative as well as qualitative aspects of the remaining gametes in the female gonads. Despite a n

Popular Abstract in English The production and use of bioethanol can help reducing the dependency on oil, and also represents a renewable source of energy. Bioethanol can be obtained from biomass such as agricultural and forest residues, after appropriate pretreatment and fermentation. This thesis addresses some of the challenges that must be overcome for the production of ethanol from biomass to The sustainable production of ethanol from lignocellulosic biomass requires the combination of efficient hydrolysis and complete fermentation of all the monomeric sugars present in the raw material. The present work was aimed at tackling some of the major challenges that will be encountered in commercial-scale ethanol production using Baker’s yeast, Saccharomyces cerevisiae, the preferred microorg

Popular Abstract in English Global invasion of our precious watercourses by cyanobacteria poses great threat to human- and animal health by deteriorating water systems. In fact, this problem is not likely to be solved in the near future as cyanobacteria are associated with pollution of waterways. Consequently, water sources are subject to contamination by natural toxins produced by abundant growthCyanobacteria blooms are a water menace since they produce potent toxins that have been implicated in poisonings and deaths of humans and animals after consumption or contact with cyanotoxin-contaminated water. Of particular concern are cyanotoxins called microcystins, which are hepatotoxic cyclic peptides known to promote development of liver tumors in humans and animals. The high toxicity and in

The purpose of this study is to shed light on what motives social work students have in their choice of career, more specifically what their perceptions are regarding social services and how this guides them in their choice of career. The key research question is: how can we understand social work students’ motives in their choice of profession and career paths? The analysis is guided by the two c

It will observe roughly one billion stars, quasars and other point like objects for which the five astrometric parameters (position, parallax and proper motion)

SynopsisReactivity trends of thioethers toward square-planar complexes can be generally interpreted by use of an equation of the form: log k = γ + α∑σ* + βθ, where k denotes second-order rate constants, ∑σ* the sum of Taft constants for the thioether substituents, and θ the thioether cone angles. γ represents an intrinsic parameter for each substrate complex, while α is an electronic and β a steriSynopsisReactivity trends of thioethers toward square-planar complexes can be generally interpreted by use of an equation of the form: log k = γ + α∑σ* + βθ, where k denotes second-order rate constants, ∑σ* the sum of Taft constants for the thioether substituents, and θ the thioether cone angles. γ represents an intrinsic parameter for each substrate complex, while α is an electronic and β a steri

This thesis examines two different impacts of sidestream treatment of digester supernatant via nitrification-denitrification in a sequenced batch reactor (SBR). One of the impacts is the detrimental formation of nitrous oxide, and the other is the positive boosting of nitrifiers to the mainstream process through bioaugmentation. The studies have been carried out in a full-scale wastewater treatmenThis thesis examines two different impacts of sidestream treatment of digester supernatant via nitrification-denitrification in a sequenced batch reactor (SBR).

The banking and financial services industry is experiencing a significant transformation driven by factors such as regulatory changes, customer demands, and the growing focus on data. This evolution has given rise to the concept of open finance, an extension of open banking that encompasses various financial sectors. Open finance aims to promote data sharing and access across the industry, with th

Too dangerous to forget – a semiotic and contextual study of the memorial Romanoparken – Sång om en plats This essay examines the memorial Romanoparken – Sång om en plats (2020), which embodies Roma memories. However, there are risks with memorials when they take the material form of a monument that they are seen as completed actions and the completion can lead to distancing oneself from the

Particles that are a hundred- to ten thousand times smaller than the width of a hair are commonly referred to as colloidal particles. Colloidal particles occur in a variety of products, like foodstuffs (marmelade and dairy products), construction materials (cement) and stained glass. In water, these particles are strongly affected by the Brownian force: an force that was discovered in 1827 by the Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction. Mixing two microgels that collapse at different

This dissertation deals with the effects of coherence and correlations on transport through nanostructures. Simulations are mainly performed using the second order von Neumann approach, a method capable of dealing with these effects in the presence of higher order tunneling. We see that such effects can result in various kinds of current suppression as well as efficient thermoelectric devices. Fu
