Katalysatorer är viktiga komponenter i den kemiska industrin. Deras användning tillåter kemiska processer att ske på ett ekonomiskt och miljövänligt sätt, förutsatt att de är stabila och har bra aktivitet i den kemiska miljön där de tillämpas. Ett viktigt steg vid implementeringen av nya kemiska processer är alltså att utveckla lämpliga katalysatorer. Processen att utveckla sådana kan vara väldigtEstablishing a technically practical method to generate representative model catalysts for the use in characterizations and testing prior to catalyst implementation in chemical process units would allow for a more sophisticated understanding of the underlying catalytic mechanisms. As a step towards establishing such a method, generating non-agglomerated, spherical NiMo nanoparticles, with diameter

Uppsatsen syftar till att förklara varför svenska lagstiftare fastställde de rådande gränsvärdena för revisionsplikt genom att identifiera vilka intressegrupper och faktorer som kan tänkas ha påverkat beslutet. Vi gjorde en kvalitativ studie över lagändringsprocessen, SOU 2008:32. Vidare använde vi en induktiv forskningsansats vid analys av de offentliga statliga dokumenten samt remissyttranden. UThe purpose of the study was to explain why the Swedish government chose the current threshold for audit exemption. This was done by identifying which interest groups and factors that may have affected the government’s decision. The study was done by using a qualitative method when analysing the law change process, SOU 2008:32. Furthermore, an inductive approach was used when analysing the public

Rättskällornas uppgift är att belysa rättsordningen och att bidra till förutsebarhet och transparens i rättsystemet genom att hjälpa yrkesverksamma jurister att uttolka gällande rätt. En rättskälla kan sammanfattas som det material yrkesverksamma jurister beaktar och hänvisar till i sin rättsliga argumentation. Frågan om huruvida skiljedomar kan utgöra en rättskälla bör därför besvaras utifrån detThe role of legal sources is to inform the interpretation of the law and to contribute to predictability and transparency in the justice system by helping practicing lawyers to interpret current law. A source of law can be summarized as the material that practicing lawyers use and reference in their legal argumentation. The question whether arbitral awards should be recognized as sources of law mu

Den tekniska utvecklingen och globaliseringen har i grunden förändrat hur personuppgifter samlas in, sprids, används och överförs. Det som var aktuellt under början och mitten av 90-talet är idag förpassat till historien. Nya sätt att sprida stora mängder information genom sociala nätverk och så kallade molntjänster tillhör idag vardagen för många av Europas 250 miljoner internetanvändare . SamtidRapid technological developments and globalization have profoundly changed the way personal information is collected, spread, used and transferred. What was relevant during the early and mid 90's is now history. New ways to disseminate large amounts of information through social networks and so-called cloud services or cloud computing is today part of modern life for many of Europe's 250 m

Carbon deposition has a serious effect on the performance of solid oxide fuel cells (SOFCs). An unsteady-state 2D model based on COMSOL software is used to study the carbon deposition process in a planar SOFC. The carbon deposition, catalyst activity, reaction rate and temperature fields are obtained to analyse the mechanism of carbon deposition in the SOFC at different operating time. The effects

BACKGROUND AND OBJECTIVES: Transfusion of blood products in particular older products is associated with patient morbidity. Previously, we demonstrated a higher incidence of acute lung injury in lipopolysaccharide-treated sheep transfused with stored blood products. As transfusion following haemorrhage is more common, we aimed to determine whether a 'first hit' of isolated haemorrhage would prec

This paper presents a trans-disciplinary assessment of new and innovative biorefinery concepts producing high-value chemical compounds from residues from agriculture, food and forest industries. There is a significant potential of biomass residues in Sweden suitable for the extraction of various compounds, including upgrading by biocatalytic processes, in addition to current energy generation. Two

Compelling evidence identifies airway smooth muscle (ASM) not only as a target but also a cellular source for a diverse range of mediators underlying the processes of airway narrowing and airway hyperresponsiveness in diseases such as asthma. These include the growing family of plasma membrane phospholipid-derived polyunsaturated fatty acids broadly characterised by the prostaglandins, leukotriene

In Weber's writing and in leadership theory, charismatic leadership is associated with social change However, the importance and desirability of charismatic leaders in change processes can be questioned, as well as the notion that charismatic leaders are invariably proponents of change There are documented cases of charismatic leaders in religious and political contexts who have opposed ongoing ch

Patent pools are contractual agreements where patent rights are transferred to a common holding company for the purpose of jointly licensing of patent portfolios. They have posed and still constitute one of the major challenges to competition policy. The arrangements have the ability to integrate complementary technology, reduce transaction costs and avoid infringement. At the same time, they cons

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

Disposable hygiene products, such as gloves and aprons, are commonly and frequently used in healthcare environments and are essential to maintain the hygiene standard. They are placed in different types of carriers, primarily in examination rooms and are mounted on the walls. This creates some difficulties for product development and fast access because not all hygiene products fit all carriers an

Much has been written about valuing the student voice in UK higher education. The discussion runs alongside an increasing focus from university leadership on improving students’ experiences, and development of the ways in which the student voice is captured, considered, and acted upon. These techniques are central to understanding and developing student engagement (Brooman et al. 2014; Cook-Sather

Background: Register diagnoses, both hospital-based and from open clinic care, are often used in research studies in Sweden. The validity of such diagnoses has been debated and a validation assessment can improve the diagnostic accuracy for use in research studies.Objective: The aim of this study was to investigate the quality of register-derived dementia diagnoses in the Malmö Diet and Cancer pop

Cleaning is an inevitable, and often costly, part of most membrane filtration plants. The economic assessment of cleaning costs is often rather arbitrary when researchers design and estimate costs of a membrane plant in a new application. Severity of fouling, operation conditions, cleaning agents and cleaning frequency all influence the costs for membrane cleaning. In addition to the costs of the

This overview of progress made in preventing post-traumatic osteoarthritis (PTOA) was delivered in a workshop at the Orthopaedics Research Society Annual Conference in 2019. As joint trauma is a major risk factor for OA, defining the molecular changes within the joint at the time of injury may enable the targeting of biological processes to prevent later disease. Animal models have been used to te

Strut-based structures, such as lattices, produced using additive manufacturing (AM) offer significant potential for applications requiring lightweighting and structural compliance. However, conventional Design for AM (DfAM) approaches often assume idealised material behaviour, which can be misleading for thin strut-based structures where geometric parameters and process-induced effects significan
