This contribution presents a novel model-based methodology for open-loop optimal control of batch high-pressure liquid chromatographic (HPLC) separation processes. The framework allows for simultaneous optimization of target component recovery yield and production rate with respect to a parameterization of the input elution trajectory and fractionating interval endpoints. The proposed methodology
Yearly 3.3 million premature deaths occur worldwide due to air pollution and NOx pollution counts for nearly one seventh of those [1]. This makes exhaust after-treatment a very important research and has caused the permitted emission levels for NOx to decrease to very low levels, for EURO 6 only 0.4 g/kWh. Recently new legislation on ammonia slip with a limit of 10 ppm NH3 has been added [2], whic
There is an ongoing shift to mobility in business IT, as well as in the consumer space. Users do not demand mobile availability anymore, they simply expect the ability to access business IT with consumer devices. Stemming from this demand, mobile business intelligence (BI) has emerged as a response from the BI industry. Thus, mobile BI is an extension of traditional BI into mobile devices. In line
A well-functioning public transport is a central part of a sustainable society. Public transport fills not only an important function for the movement of people, public transport also provides a large economic benefit in terms of security and environmental benefits. It is therefore of great importance that public transport has the ability to provide good and qualitative trips so that it can seriou
As a result of technological advancements, marketing of various shapes have ex-ploded. In today's society it is not a question of where, what or how to spread a message, it's about getting someone to listen. This paper aims to raise awareness of the role of music in marketing, specifically how music in advertising can affect consumers' perception of and approach to an enterprise. By de
Turbo systems have long been implemented into vehicles to increase the specific power. Increasing the pressure for conventional vehicles decreases the mass of the engine and increases the efficiency. Conventional vehicles do however produce carbon dioxide emissions which have become an increasing issue that needs a solution. One possible solution is the fuel cell utilizing hydrogen as fuel. This r
The fundamental principle of investing, applicable at both systematic and individual levels, is the art of balancing the portfolio between expected returns and acceptable risk exposure. Risk management involves predicting the direction of the underlying asset’s movement and taking appropriate actions accordingly. Traditionally, statistical models such as GARCH have been used to achieve this object
Global population growth presents challenges to sustainable food and energy produc- tion. Transitioning to renewable energy sources, like solar power, requires significant land allocations, conflicting with the need for arable farmland. Agrivoltaics (AV) offers a potential solution by integrating crops and solar panels on the same land. Ensuring consistent and adequate agricultural output alongsid
This thesis evaluates the risk parity and tail-risk parity approach against conventional weight budgeting approach. The risk parity and tail-risk parity approach, in contrast to weight budgeting approach, is about distributing the risk between the asset classes in the portfolio. The risk, is traditionally measured in terms of volatility together with the assumption that returns follows a Gaussian
In his "A Theory of Justice", the American philosopher John Rawls presented two principles concerning justice. The first of these principles states: "Each person is to have an equal right to the most exstensive total system of equal basic liberties compatible with a similar system of liberty for all." The latter is dividied into two further principles: "Social and economic
The present study explores the value and role of the physical space of the public library from the perspective of the visitors in the context of digitalization. The qualitative research was based on semi-structured interviews with regular visitors of Idé A Drottninghög (Helsingborg, Sweden), Idé A library staff members, and collaborative organizations of Idé A that make use of the library’s physic
Electrifying heavy-duty vehicles at large sites requires charging infrastructure designs that balance cost and robustness. This article quantitatively compares six different charging infrastructures, spanning centralized vs. decentralized layouts and AC vs. DC distribution through a case study of a 50-charger site (≈15 MW total). Capital costs (cables, converters, transformers) are modeled, and e
Why, despite decades of warnings and solutions, does unsustainable consumption still persist? What keeps societies locked into business as usual even when the consequences are clear? This book contends that part of the answer lies in the myths we adhere to – powerful narratives that normalise the status quo, limit imagination and delay the transition to sustainability. Gathering leading scholars f

Integration of emerging membrane processes [i.e., forward osmosis (FO), membrane distillation (MD), reverse electrodialysis (RED)] and mature membrane processes [i.e., reverse osmosis (RO)] can address the need for efficient desalination solutions. Utilization of different membrane units in pre- and post-treatment stages allows lowering the energy requirements and environmental impacts of the proc
BACKGROUND: Acute allergic reactions (AARs) occur shortly after exposure to an allergen, and the severity is on a continuum. Systemic corticosteroids (CS) are mainstay treatment of moderate to severe AARs, whereas those at risk of the most severe AARs (ie, anaphylaxis) are also recommended prescription of epinephrine autoinjectors. There is limited research on the impact of AARs not fulfilling the
INTRODUCTION: Climate change is one of the 21st century's biggest public health issues and health care contributes up to 10% of the emissions of greenhouse gases in developed countries. About 15 million laparoscopic procedures are performed annually worldwide and single-use medical equipment is increasingly used during these procedures. Little is known about costs and environmental footprint of th
Billions of birds migrate every year. To conduct a successful migration, birds undergo a multitude of physiological adaptions. One such adaptation includes adjustments of immune function, however, little is known about intraspecies (between-individual) and interspecies (between-species) variation in immune modulations during migration. Here, we explore if early and late migrating individuals diffe
Geophysical methods are prone to fail in an urban environment as all sources of noise are present in cities. The Fælledparken Park, a large open space area in Copenhagen, Denmark is not an exception. However, an extension of the metro along sections of high variability on the surface of a limestone surface motivated the use of geoelectrics as complement to seismic methods. The site conditions haveGeophysical methods are prone to fail in an urban environment as all sources of noise are present in cities.

Quantitative reconstructions of past land cover are necessary to determine the processes involved in climate-human-land-cover interactions. We present the first temporally continuous and most spatially extensive pollen-based land-cover reconstruction for Europe over the Holocene (last 11g€¯700g€¯calg€¯yrg€¯BP). We describe how vegetation cover has been quantified from pollen records at a 11 spatia
