During the process of biomass gasification tars are formed which exit the gasifier in vapor phase. Tar condensation creates problems like fouling and plugging of after-treatment, conversion and end-use equipment. Gasification tars consist mainly of Polycyclic Aromatic Hydrocarbons (PAHs). Former research has shown the possibilities and difficulties of tar conversion by partial combustion. Basic st
Popular Abstract in Swedish Genom att använda marina sedimentkärnor från havbotten kan vi dyka ner i forna tiders hav och förstå hur klimat och havsmiljö har utvecklats över tid. Sedimenten och dess innehåll av olika mikrofossil utgör ett fantastiskt miljöarkiv och ju längre ner i sedimenten vi kommer desto äldre är de vanligtvis. I mitt doktorandprojekt har jag studerat marina sediment från kusteThere is a limited understanding of how the benthic environment within upwelling regions responded to past rapid climatic changes. Within this thesis, a multiproxy approach is applied to two marine sediment cores from two coastal upwelling sites in the low latitude subtropical Atlantic. With a focus on benthic foraminiferal faunal analyses, the response of the benthic environment to rapid climatic
Adela Innovation is a company in a situation similar to many other small and medium sized enterprises in Sweden today. The question about internationalisation is important because the development on the Swedish market is declining, but the company still is very small in an international context. Adela Innovation needs to find markets to enter, that are of an appropriate size and that don’t require
The 1998 State Street Bank &&semic Trust Co. v. Signature Financial Group, Inc. case took American patent law into a new era. A method of doing business is no longer a valid ground for rejection of patent applications, and the words that ''[v]irtually anything is patentable'' echoe in the legal and business societies. By rendering a data processing system configured for
In the modern business environment, there is growing number of companies placing weight on sustainability-related issues, such as waste management, local communities, use of resources etc. At the same time such stakeholders as investors, consumers, employees and communities are increasingly interested in understanding company’s efforts and progresses in the area of sustainability. With that respec
Depth data and bathymetry maps are used to analyze their association with tides, winds, currents and wave conditions in the port of Talara, at the coast of northern Peru. The objective is to investigate the processes that influence the sediment transport in the port. The sedimentation affects the saltwater pumps for fire fighting, obstructing them from delivering water since their operational wate
In Sweden, there is a great demand for construction. At the same time, construction companies must increase their profitability. This requires the development of systems for improved communication and interaction. Especially now when the industry is facing massive retirements, there is a risk that knowledge will be lost. To ensure quality the companies also need to involve their employees so they
Spurred on by pressure to find sustainable energy production alternatives to fossil fuels, many industries have been acquiring land in order to plant crops for biofuel production. In Tanzania, biofuel development is in an early stage, and over the last decade, several foreign actors have tried to start up biofuel projects in the country (without success). Land acquisitions are seen by many as a fo
The reliability of energy supply is crucial for the well-being of individuals and the prosperityof countries. At the same time, energy production is closely connected to CO2 emissions,which is believed to have an important impact on human-induced global warming. In light ofresultant, partly counteracting challenges, energy efficiency has gained increasing attention as ameans of ensuring energy sup
For many years the benefits of using stockings that exert a pressure on the legs, to prevent and treat a number of health conditions, have been well known. For just as many years carers and caretakers have been struggling to put on these stockings onto the legs. The high compression strength of the stockings makes it very difficult to put them on the way one does with ordinary stockings. Today, me
On-going debates within feminist and social science research are increasingly highlighting the need for reflexive scholarship (particularly within qualitative research) – both in terms of considering the emotionality of the research process (Brownlie 2014, Burkitt 2012, Doucet 2008, Holland 2005, Mauthner and Doucet 2003) and in terms of applying an intersectional lens and discussing researchers’
Turbulent non-premixed flames with local extinction and re-ignition exhibit multiple combustion modes including ignition waves, diffusion flames, partially premixed flames, and ignition-assisted partially premixed flames. The mechanisms of local extinction and re-ignition are not well understood and numerical modeling of multi-mode combustion is a challenging task. In this work, a specially design

Background: Physical inactivity is a worldwide public health issue and the fourth leading risk factor for global mortality. As a measure of prevention or treatment several countries have developed concepts of physical activity on prescription (PAP) to tackle the common issue of sedentary behavior and thereby decrease the risk of chronic illness and premature death. The Swedish model of PAP, “Fysis
The world is in transition. Europe is a Europe of transition. And so is the city; an incomplete, ever-changing and complex construct. While life itself is built upon the concept of change, organic order and vitality, society is currently finding itself struggling not to fall behind time. The Industrial Revolution has led to greater productivity and larger economic turnovers. Developments picked
This project involved the testing and establishment of a base combustion procedure for the newly acquired Raddec Gen IV PYROLYSER and focused on the optimization and correction of the laboratory’s previous liquid scintillation counting (LSC) procedure using the Hidex 300 SL. The pyrolyser was verified to be operational and achieve satisfactory and consistent recoveries across the 6 combustion tub

Purpose: While the phenomenon of new product development (NPD) and cycle time in general is sufficiently covered in the literature, a clear picture of the NPD length in startups has not been available so far. Simultaneously, the literature emphasizes the entrepreneurial perception and judgment as major factor for the success of a business, but does not specifically refer to the NPD cycle time.
In the post-genomic era, it has become evident that genetic changes alone are not sufficient to understand most disease processes including pancreatic cancer. Genome sequencing has revealed a complex set of genetic alterations in pancreatic cancer such as point mutations, chromosomal losses, gene amplifications and telomere shortening that drive cancerous growth through specific signaling pathways
