As part of the development of a process for production of a lignin-rich oil that can serve as a renewable feedstock to existing petroleum refineries, hydrogen assisted depolymerization of lignin in filtered black liquor has been investigated. This process offers the possibility to reduce fossil emissions from transportation by utilization of the largest renewable carbon resource in Sweden, namely

I en teoretisk studie har användbarheten av thermosyphoner för att förbättra säkerheten och effektiviseringen av kemiska reaktorer. Thermosyphoner är en simpel form av en ”heat pipe”, ett ihåligt och slutet rör som är delvis fyllt av en fluid. Om röret värms upp till fluidens kokpunkt inleds en inre fasomvandling vilket används för att förbättra rörets värmeledningsförmåga. Tre simuleringsmodellerIn a theoretical study the use of thermosyphons to improve the safety and efficiency of chem-ical reactors have been evaluated. Thermosyphons is a simple form of a “heat pipe”, a hollow and closed tube that’s partially filled with a fluid. When the pipe is heated up to the boiling temperature of the fluid within a phase change is initiated. The phase-change is used to im-prove the thermal conducti

Syftet med uppsatsen är att fördjupa förståelsen av hur familjeföretag kan lyckas under successionsprocessen genom att illustrera en framgångsrik succession i ett familjeföretag i Sverige. För att nå syftet genomfördes en kvalitativ studie i form av semistrukturerade intervjuer. Studien har haft en socialkonstruktionistiskt och tolkande utgångspunkt. Studien är baserad på tidigare forskning om fam

I denna uppsats utreder jag vilken rätt gifta barn har att återförenas med sina föräldrar eller med sin make eller maka. Detta för att ur ett barnrättsperspektiv utreda om ett ingånget barnäktenskap begränsar barns rätt till familjeåterförening. Syftet är även att undersöka på vilket sätt principen om barnets bästa förhåller sig till gifta barns rätt till familjeåterförening, för att sedan utreda From a child’s rights perspective this essay seeks to investigate whether child marriage restricts children’s right to family reunification. In this essay I therefor study what rights married children have to reunite with their parents or with their spouse. The purpose of this essay is also to investigate how the principle of the best interest of the child relates to married children’s right to fa

Cosmopolitan theory has long argued that the world is becoming increasingly interconnected. Through borderless phenomena such as climate change, and through globalizing processes such as cross-border mobility and the global market, we are becoming increasingly aware of their social and political impact as global news and debates fill our social media channels. To this end, cosmopolitan theory argu

Ett patent är en immateriell rättighet som medför en ensamrätt för patenthavaren att dra affärsmässig nytta av en viss uppfinning under en begränsad tidsperiod. Den som kränker patenthavarens ensamrätt gör sig skyldig till patentintrång. Vid patentintrång tillhandahåller den svenska patentlagen (1967:837) ett antal olika sanktionsmöjligheter. De primära civilrättsliga sanktionsformerna utgörs av pA patent is a kind of intellectual property right that grants the patent holder an exclusive right to profit from a certain invention for a limited time period. Anyone who violates the patent holder's exclusive right is guilty of patent infringement. In cases of patent infringement the Swedish Patent Act (patentlag 1967: 837) provides a number of different sanction options. The primary civil s

This study examines the roles of transitional justice and reconciliation in post-conflict societies and the relationship between these two concepts. There seem to be a widespread pessimism regarding the possibility of combining these two concepts in a post-conflict situation due to what is described as a fundamental tension between justice and reconciliation. However, I find that the connection an

This thesis aims to explore the relevance of identities for the support of democracy in Ukraine. It elaborates on the assumption that the identity's construction affects which ideas are embraced and sets out to test whether a civic as opposed to ethnic identity construction would correlate with the embracing and pursuit of the idea of democracy. Material gathered during a Minor Field Study - i

Public participation has gradually gained a stronghold within development theory during the last three decades. Researchers, policy-makers and aid workers share the belief that inclusion of beneficiaries in the development process is a prerequisite for purposeful and sustainable development of rural communities. The purpose of this thesis is to examine if participatory development leads to empower

We report on fabrication and optical characterization of GaAs nanopillar (NP) arrays, obtained using a combination of low-cost mask generation by self-assembled silica particles (nanosphere lithography) and dry etching. Tapered structures (conical and frustum NP arrays) are fabricated by appropriate optimization of process parameters. Significant suppression of surface reflectance is observed for

Digital gameplay is now firmly embedded in everyday practices in many Scandinavian homes. This paper deals with the constitution of such practices in families by taking a closer look at the material objects essential to play and their role in the “design of everyday life” (Shove et al 2007). It uses ethnographic method and anthropological practice theory to attend to the domestic spaces of leisure

This study uses a generalized linear model approach, i.e. negative binomial regression, to develop a predictive model for motorcycle fatal accidents on Malaysian primary roads. For the modeling process, a huge data inventory has been carried out, integrating the road geometry features, fatal accident records and traffic censuses from 3 selected states for the past 3-year period. The results show t

One major problem for integrating study results into a common body of knowledge is the heterogeneity of reporting styles: (1) It is difficult to locate relevant information and (2) important information is often missing. Reporting guidelines are expected to support a systematic, standardized presentation of empirical research, thus improving reporting in order to support readers in (1) finding the

The paper discusses the solution to the optimal adaptive control problem over an extended time horizon. This leads to a controller that have dual features, i.e., tt uses control actions as well as probing actions. The solution of the optimal dual control problem is intractable from a computational point of view. Approximations to obtain simpler suboptimal dual controllers are thus important. There

Popular Abstract in Swedish Inom forskningen kring rengöring och processhygien är det viktigt att förstå de bakomliggande mekanismerna för depositionen av partiklar och makromolekyler på ytor. Depositionsprocessen kan beskrivas som transporten av partiklar till ytan och den påföljande adhesionen. Om de hydrodynamiska krafterna är tillräckligt starka kan partiklarna åter transporteras bort från ytaIn the research area of cleaning and process hygiene it is important to understand the underlying mechanisms behind the deposition of particles and macromolecules onto surfaces. The deposition process is described as the transport of particles to the surface followed by attachment. If the hydrodynamic forces are strong enough, the particles can be re-entrained. In this work particle deposition wa

This paper is built upon recognizing the need that digital forensic investigators are required in many cases to investigate, understand and report on all kind of cyber-crime including novel security breaches which have not been performed in the past. When an investigator is faced with the challenge to explore a new threat, we argue that the inquiry dynamics do not differ from an organisational emp

The performance of continuous time deltasigma modulators is limited by their large sensitivity to feedback pulse-width variations caused by clock jitter in their feedback DACs. To mitigate that effect, a dual switched- capacitor-resistor feedback DAC technique is proposed. The architecture has the additional benefit of reducing the typically high switched-capacitor-resistor DAC output peak current

The recent discovery of a topological phase transition in IV-VI narrow-gap semiconductors has revitalized the decades-old interest in the bulk band inversion occurring in these materials. Here we systematically study the (001) surface states of Pb1-xSnxSe mixed crystals by means of angle-resolved photoelectron spectroscopy in the parameter space 0 <= x <= 0.37 and 300 K >= T >= 9 K. Using the surf
