Volatile fatty acids (VFAs) are key platform chemicals used in a multitude of industries including chemicals, pharmaceuticals, food and agriculture. The current route for VFA production is petrochemical based. VFAs can be biologically produced using organic wastes as substrate, therefore directly contributing to a sustainable economy. This process is commonly known as acidogenic fermentation (AF).
To understand, predict and mitigate climate change, it is crucial to have long-term and standardised measurements of greenhouse gas concentrations in the atmosphere and their fluxes between atmosphere, land and oceans. The Integrated Carbon Observation System, is a distributed European Research Infrastructure which provides high-precision and highly standardised observations from more than 170 sta
Two new membrane concepts have been piloted have been piloted in in recent years at Lund University in Sweden – namely (1) direct membrane filtration (DMF) and (2) water harvesting. Both concepts use submerged membranes as the established membrane bioreactor (MBR) concept but they exclude a biological treatment. This presentation will showcase the latest developments and experiences with these two
Submerged membrane modules either in flat or hollow fibre configuration have established themselves as a standard module for membrane bioreactors (MBRs) in municipal and industrial wastewater treatment. In recent years two new concepts using submerged membrane modules have been developed for (1) direct membrane filtration (DMF) for municipal wastewater treatment and for (2) storm and rain harvesti
Photosensitizers for sensitized triplet-triplet annihilation upconversion (sTTA-UC) often rely on precious heavy metals, whereas coordination complexes based on abundant first-row transition metals are less common. This is mainly because long-lived triplet excited states are more difficult to obtain for 3d metals, particularly when the d-subshell is only partially filled. Here, we report the first
In this study, we report on reactive large-eddy simulations (LESs) of flow and combustion in the U.S. Air Force Research Laboratory Research Cell 19 cavity-based scramjet combustor. This case involves the combustion of ethylene that is injected into a cavity. It has previously been studied experimentally with multiple techniques, including particle image velocimetry, hyperspectral imagining, and l
In recent years, lipid bicontinuous cubic liquid-crystalline nanoparticles known as cubosomes have been under investigation because of their favorable properties as drug nanocarriers useful for anticancer treatments. Herein, we present organic/inorganic hybrid, theranostic cubosomes stabilized in water with a shell of alternate layers of chitosan, single strand DNA (model genetic material for pote
AIM: To illuminate from the perspective of nurses in ambulance services the experiences of using a web-based advisory decision support system to assess care needs and refer patients.DESIGN: Inductive and descriptive approaches.METHOD: Thirteen semi-structured interviews were conducted in the spring of 2020. The data were analysed through the reflexive thematic analysis.RESULTS: The Swedish web-bas
In language acquisition it is important to imitate the native speakers of the language. For the young child it is natural to imitate both the language and the behaviour of the culture. Imitation, or adaptation (Markham 1997), is also useful in second language acquisition to learn how to pronounce the words and to learn the prosody of the language. For most people it is difficult to learn to speak
This paper presents a combinatorial auction which is of particular interest when short completion times are of importance. It is based on a method for approximating the bidders' preferences over two types of items when complementarity between the two may exist. The resulting approximated preference relation is shown to be complete and transitive at any given price vector. It is shown that an appro
It is well known that Max-Weight type scheduling algorithms are throughput optimal since they achieve the maximum throughput while maintaining the network stability. However, the majority of existing works employing Max-Weight algorithm require the complete channel state information (CSI) at the scheduler without taking into account the associated overhead. In this work, we design a Scheduling and
The influence of cross-flow velocity and transmembrane pressure on the optimal back-shock frequency and normalized net flux during back-shocking has been studied using a semi-analytical mathematical model. The model uses the flux as a function of time without back-shocking together with knowledge of the streamlines and pathlines during the back-shock cycle to predict the optimal normalized net flu
When calculating the production costs input data can vary considerably inquality between different cases. When costs pertain from products, which are already in production, complete and reliable data may already be available. For new products, new production systems or new production technology it might be hard to find applicable and reliable data. The cost and performance parameters needed can th
Popular Abstract in English This book investigates marketing work in professional service organizations from a rhetorical perspective. It comes to the conclusion that this work is accomplished by self-reflexive marketers who are reminiscent of the ancient sophists – a diverse group of itinerant advisors whom came to Athens around the fourth century BCE for business reasons. Marketers travel – as dMarketing has traditionally been understood from the perspective of marketing management. This causes problems when we study marketing practices because the normative discourse of marketing management is not particularly useful for describing the day-to-day work of marketing practitioners. This calls for marketing research from new perspectives. Rhetorical business – A study of marketing work in t
‘Virtual imagery as evidence in the contemporary context of the war on terror’ This paper explores the evidentiary role of virtual reproductions produced by the research project Forensic Architecture in the context of the contemporary battlefields of the war on terror. The digitization of war has created a networked landscape whose processes often remain invisible to the public. Although drone op
Popular Abstract in Swedish När vi äter kolhydrater, fett, protein och andra näringsämnen sker kemiska reaktioner i kroppen som kan liknas vid dom som sker när man eldar en brasa. Vid förbränning reagerar kolhydrater med syre och bildar koldioxid och vatten. Denna förbränning frigör den energi som funnits lagrad i kolhydraterna, i brasan i form av värme, och i kroppens celler omvandlas den till keNADH:quinone oxidoreductase, or complex I, is a large, complex and poorly understood bioenergetic enzyme in the respiratory chain of living organisms. The enzyme has a conserved core structure, comprising fourteen protein subunits: Seven subunits protrude from the membrane and contain a flavin prosthetic group and eight iron-sulfur clusters that guide electrons from the oxidation of NADH towards t
Antonymy and negation are phenomena that can be studied from many perspectives. In the literature, antonymy is recognized as the most robust of the lexico-semantic relations, important to both the mental organization of the vocabulary and the organization of coherent discourse (Cruse 1986, Fellbaum 1998, Murphy 2003, Willners 2001 and Jones 2002). "Depending on whom you ask, negation may be a logi
Critical infrastructures provide essential services for the functioning of the society, and vulnerability analysis is an important basis for decisions concerning increasing their robustness against strains. Since critical infrastructures can be regarded as complex systems, such analyses can prove challenging. To analyze the system response to strains, several different functional models have been
Introduction: Moral distress arises when healthcare workers face difficult decisions without adequate information and/or when patient care is compromised due to limited resources, communication issues, or altered work routines in exceptional circumstances. While moral distress in maternity and neonatal healthcare workers (MNHCWs) has been noted, its prevalence, intensity, and impact on well-being
