In fixed-bed reactors, the use of large particles in thermally thick regimes is common, which underscores the need for a comprehensive understanding of intraparticle processes. However, integrating detailed particle models into fixed-bed simulations is computationally expensive. This study introduces a tabulation method for biomass conversion’s drying and pyrolysis stages, where significant mass e

Lignins are a polymeric, renewable resource with remarkable structural diversity. Research is being conducted into the valorisation of lignins into value-added products. The absence of experimental libraries, in particular for process-modified oligomers, hampers analytical feedback to these valorisation efforts. Stochastic methods for generating libraries in-silico have been proposed, but were not

Populärvetenskaplig sammanfattning: Beskrivning och kartläggning av vegetationen samt tolkning av jord, klimat och annan information är mycket viktigt för förståelse och planering för användande av naturresurser. Fenologi dvs växters årliga variationer, är nära korrelerad med dynamiken i atmosfären. Information om vegetationens fenologi på regional och global nivå är därför en viktigt komponent föVegetation phenology (seasonal rhythm) is closely related to seasonal dynamics in the lower atmosphere and is therefore an important element in global climatic models and vegetation monitoring. Remote sensing is the primary means by which we can observe the dynamic characters of the earth's biosphere. Description and mapping of the natural vegetation, and its interpretation in terms of soil, c

By using data from Ecovision on the DJ AIG commodity index made up of commodity futures and the OMX index consisting of Swedish equities I have estimated the correlation between Swedish equities and US commodity futures. The correlation has been examined in a multivariate GARCH setting by using the BEKK model. The purpose has been to examine if commodity futures from a US exchange market can impro

The notion of human rights is built on the fact that they are universal rights and thus applies to everyone without exceptions. Despite this irregular workers are denied their labour rights and their human rights due to the fact that they are living in a country unlawfully. The states use methods as regularizing irregular migrants or enabling tougher sanctions against irregular migration in order

Since the adoption of the Charter of the United Nations the pattern of conflict in the international arena has drastically changed. From largely being a scene for inter-state conflicts, internal conflicts have predominated the post-war era. The few international conflicts that the post-war world has witnessed have originated in civil conflicts. The principle of non-intervention implies the duty fo

In the spring of 2005, the Treaty Establishing a Constitution for Europe (CT) was rejected in French and Dutch referenda. The document, that was to lead the recently expanded European Union (EU) into the future, was instead put on pause for reflection. Why was there such fear and scepticism towards the CT? What was the CT really all about? In this analysis of the CT, I look at the CT from three le

Over the past decades, sustainable production and consumption pattern has been addressed on a global level. Business is a powerful stakeholder in the development of sustainable consumption and production systems as it represents a great proportion of competence, resources and mechanisms (Charter, Gray, Clark and Woolman, 2008). The global approach toward achieving sustainable production and consum

An analysis on selecting cutting speed, cutting feed and depth of cut when collecting data for the Colding Tool Life Model based on Woxen's Equivalent Chip Thickness was performed to achieve the lowest possible model error. All possible combinations of a large data set were evaluated with regard to model error. This work shows that an increase of ratio between the highest and lowest cutting speed,

During the past one and a half decades ambient pressure x-ray photoelectron spectroscopy (APXPS) has grown to become a mature technique for the real-time investigation of both solid and liquid surfaces in the presence of a gas or vapour phase. APXPS has been or is being implemented at most major synchrotron radiation facilities and in quite a large number of home laboratories. While most APXPS ins

Introduction: Product-oriented environmental law is an expanding, poly-thematic subsection of environmental law. First, an increasing number of policy instruments are being used at the international, European and national levels to regulate products, including mandatory performance standards, consumer subsidies, public procurement practices, product bans, taxes and charges and various kinds of man

A prototype of a surface emissions trap, a new device for reducing emissions of volatile organic compounds and particulate matter from surfaces while allowing evaporation of moisture, was used to improve the indoor air quality of a school building with elevated air concentrations of 2-ethyl-1-hexanol. A clear improvement of the perceived air quality was noticed a few days after the trap had been a

Intensive agricultural management negatively affects both natural enemies of pests and pollinators. Such management also has the potential to adversely affect the ecosystem services that these communities confer. Organic management has been proposed as an alternative method to mitigate such problems by restoring the services provided by arthropod communities. We evaluated the effect of organic

The starch industry is a key sector of the European food industry with an annual turnover of approx. €4 billion. The production processes in the starch industry are still dominated by conventional separation processes such as evaporators, separators and rotary vacuum filters (RVFs). Membrane processes are only rarely used. This presentation will show how membrane processes can be used to optimise

This paper evaluates the utility of the feedback particle filter (FPF) for state estimation of SE(2)-configured dynamics in a real-time context. The filter is implemented in discrete time to fuse gyroscopic-and accelerometer measurements with Ultra-Wideband (UWB) and camera measurements. With this state information, the FPF is compared to other common filters in terms of the estimate mean square e

Membrane processes, antibiotics, enzymes, biofuels and biochemicalsThe end of the 20th century was marked by the start of the third and so far final wave of biotechnology, the so-called white biotechnology, aiming to substitute chemical processes based on C2/C3 chemistry of oil and gas by biotechnological processes. The standard conversion process in biotechnology is fermentation, which is used t

Objective: To describe the design and rationale for the genetic analysis of acute and chronic cerebrovascular neuroimaging phenotypes detected on clinical MRI in patients with acute ischemic stroke (AIS) within the scope of the MRI-GENetics Interface Exploration (MRI-GENIE) study. Methods: MRI-GENIE capitalizes on the existing infrastructure of the Stroke Genetics Network (SiGN). In total, 12 inte

It is a human fundamental to desire to be valued, loved and respected - to be significant. Social exclusion induce significance loss which elicits a 'quest for significance' - the search for opportunities to re-gain significance. The present article establishes this relation in a laboratory experiment (N = 71, mean age = 28, SD = 10.42, 65% women, 35% men), showing that socially excluded individua

The estimation of dynamic panel data models with interactive effects and moving average errors is considered. This is accomplished by making an extension to the factor analytical (FA) estimator which was originally designed for dynamic panels with fixed effects only and serially uncorrelated errors. The results show that the additional allowances have no effect on the asymptotic properties of the
