In this paper, a numerical study of flow, reactions and NOx emissions from a biomass boiler is presented. Detailed reaction mechanisms for the decomposition of tar species, combustion of hydrocarbons and formation of NOx are employed by adopting appropriate reaction sets from literature. The proposed mechanism is used to perform CFD simulations of a laboratory-scale biomass boiler, and temperature

Digital holography (DH) has been extensively applied in particle field measurements due to its promising ability to simultaneously provide the three-dimensional location and in-plane size of particles. Particle detection methods are crucial in hologram data processing to determine particle size and particle in-focus depth, which directly affect the measurement accuracy and robustness of DH. In thi

The natural products pulchrol and pulchral, isolated from the roots of the Mexican plant Bourreria pulchra, have previously been shown to possess an antiparasitic activity toward Trypanosoma cruzi, Leishmania braziliensis and L. amazonensis, protozoa responsible for the Chagas disease and leishmaniasis. These infections have been classified as neglected diseases, and still require the development

The efficiency of irrigation, as well as optimization of nutrients, affect spinach yield in all growth stages. In this study, the sensitivity of spinach (early and mature yields) to shallow saline groundwater and the effect of fertigation treatments on mature yield were experimentally investigated. The sprinkler irrigation experiments were conducted on 0.47 ha of silty clay soil at the University

Dupuytren’s disease (DD) is a fibroproliferative disorder affecting the palmar fascia of the hand. Risk factors include diabetes mellitus (DM), whereas a high body mass index (BMI) is associated with a lower prevalence of DD. The aim of this study was to further elucidate risk and protective factors for the development of DD using longitudinal population-based data from the Malmö Diet and Cancer S

Background & Aims: In 2014, the burden of hepatitis C virus (HCV) in Sweden was evaluated, to establish a baseline and inform public health interventions. Considering the changing landscape of HCV treatment, prevention, and care, and in light of the COVID-19 pandemic, this analysis seeks to evaluate Sweden's progress towards the World Health Organization (WHO) elimination targets and identify

Climate mitigation scenarios envision considerable growth of wind and solar power, but scholars disagree on how this growth compares with historical trends. Here we fit growth models to wind and solar trajectories to identify countries in which growth has already stabilized after the initial acceleration. National growth has followed S-curves to reach maximum annual rates of 0.8% (interquartile ra

Electromechanical oscillations is a power system phenomenon where generator rotors oscillate, leading to oscillatory power flows. Damping of such oscillations is important for system stability. Forced oscillations is a special case where one faulty component is the source of the oscillation. This report concerns the Dissipating Energy Flow (DEF), which is an energy-based method for analysing dampi

The purpose of this thesis was to explore how a newly founded Youth Platform in Colombia, called La Mesa de Juventud, could affect the youth community in promoting and capacitating organizational skills, youth citizenship rights and youth influence in public policy making. The study emanates from the region of northern Cauca situated in the South Western part of Colombia which is an area where you

Simulating the natural environment of living tissue with in vitro cell culture models has paved the way for scientific discoveries, and provided valuable insight into areas such as drug discovery and regenerative medicine. A new emerging technique of culturing cells on biomimetic three-dimensional scaffolds stands as a promising alternative to the traditional way of culturing cells on two-dimensio

The primary purpose of this paper is to further build on research related to capability development in order to explore hindrances and benefits of internal capability development and external partnerships as ways to improve performance. The beverage industry is used as the focus context since the companies in this industry are increasingly responding to external trends and looking for ways to deve

With the 11th century text Kitāb ādāb al-nikāḥ, the “Book on the Proper Conduct of Marriage”, the Islamic thinker al-Ghazālī (1056 –1111/447–504) replies to a contemporaneous debate within Sufi asceticism with a theology of nikāḥ. The text is part of his opus magnum, the “Renaissance of the Knowledge of dīn”, which aims at a renewal of Muslim piety and provides practical guidance to the male audie

This master thesis maps and discusses the current and future needs, wishes and challenges of office workers. The resultant contextual knowledge is utilized to develop a concept of an office chair. The work followed an exploratory design process. Initially, literature and data on various topics were researched to form an understanding of the current and future working conditions of office workers.

Anthropogenic climate change and environmental degradation demand humanity to depart from the growth imperative forming the economic structure of the world. In other words: Structural transformation is needed. Much of the sustainability debate in academy, politics, media and the public revolves around two paradigms: minor changes within the current system (e.g. green consumption, green growth) or

Over the last couple of decades, the importance of transmission capacity for telecommunications has grown. Enough upgraded, it can be used for both telephony, data transmission, cable TV, provision of movies, and a number of other services. For the provision of all these services, it is absolutely essential to have access to a transmission medium. The existing networks are often built up protected

In this thesis, the relationship between bureaucratic structures and efficiency is evaluated through a case study of the Swedish Police Authority. The collected material consists of semi-structured interviews with police officers from four different stations located in Region Syd. A theoretical framework that posits that there exist two types of bureaucratic structures, enabling and coercive, and

This case study aims to investigate how Arla responds to negative comments posted to their social media in order to gain knowledge of how they take into consideration Issues Management in their social media communication. Through a netnographic observation and two in-depth interviews with Arlas press- and media manager we gather empirical material. The netnographic observation is used to gather co

Secondary packaging solutions presently used to package food goods in e-commerce supply chain are either taken from old supply chains, or sub-optimally developed in a non-holistic manner. Due to the increase use of the Internet in Europe to perform online food purchases, secondary packaging must be adapted to meet these new needs. Therefore, a secondary packaging solution for a Dutch e-grocer was

In the last few decades, researchers have identified many systematic errors – cognitive biases – in the human mind. The predominant notion of human beings as rational have gradually been flawed, in one context after another. In the last few years scholars have approached the question of what policy implications should be derived from these findings and what solutions there might be. Three main phi
