At the interface between two regions, for example the air–liquid interface of a lipid solution, there can arise non-equilibrium situations. The water chemical potential corresponding to the ambient RH will, in general, not match the water chemical potential of the solution, and the gradients in chemical potential cause diffusional flows. If the bulk water chemical potential is close to a phase tra

Endothelins (ETs) are a family of novel regulatory peptides and various lines of evidence suggest an important role for ETs in regulating pulmonary function. Two receptors for endothelin, ETA and ETB, have been found in the human lung, and according to recent studies a non-ETA receptor seems to mediate the contraction of large sized human bronchi. Several studies have emphasized the importance of

Objective: Two patients who suffered acute failure of their St Jude Medical Masters aortic valve prostheses due to leaflet arrest that were unrelated to suture material are presented. It was hypothesized that the valves failed because force applied to bear upon the valve annulus caused the hinge mechanism to become restricted or to arrest. Methods: A study was designed to measure the force that wo

The in vitro digestion of a self nano-emulsifying drug delivery system (SNEDDS) was visualized by cryogenic transmission electron microscopy (Cryo-TEM). The dynamic lipolysis model, simulating the environment of the gastrointestinal tract in fasted conditions, was used for this purpose. The results revealed that micelles are present during the entire lipolysis process. Oil droplets from the self n

Health has been a central concept in nursing science since the 18th century but the holistic concept of health that includes both the body and the soul, still has to be clarified. The concept of health is often unclear and represents an unreachable ideal state that can be hard to use as a realistic goal in nursing care. The aim of this study was to describe how the patient perceives the concept of

This paper presents a model-based method to aid in the process validation for the purification of pharmaceutical drugs. The critical process parameters are identified by simulating process disturbances, and this information is then used to determine if the process control space is robust. Simulations are chosen to analyze the entire control space to also find nonlinearities and interaction effects

This paper treats controller design and tuning for systems with two input signals and two output signals in the process industry. Two design methods that can be combined to form a core in an algorithm for automatic design and tuning for the considered systems are presented. The proposed controller consists of a decoupler and a diagonal PID controller. The decoupler has the property that as little

This thesis consists of two separate papers in strategy-proof social choice theory. The first paper, “Generalizing the Gibbard-Satterthwaite theorem: Partial preferences, the degree of manipulation, and multi-valuedness”, generalizes the Gibbard-Satterthwaite theorem in three ways: firstly, it is proved that the theorem is still valid when individual preferences belong to a convenient class of par

Popular Abstract in Swedish Det mystika arvet: om konsten att erhålla och förklara det (och förstå litegrann): Ett turkiskt exempel.

Purpose: Relapse after allogeneic hematopoietic cell transplantation (allo-HCT) remains the first cause of transplant failure in patients with Philadelphia-positive (Ph ) acute lymphoblastic leukemia (ALL). In other hematologic malignancies, therapeutic advances resulted in significant improvement over time in survival of patients relapsing after transplant. Experimental Design: We compared outcom

The world today faces many different environmental problems, which has a negative effect. These are both global, regional and local, which means that they affect all people. To be able to overcome this and be able to promote a long-term sustainability, it is essential that all contribute and take responsibility for it. An example of doing this is to get more people to commute rather than using the

Denna uppsats utforskar hur resning i brottmål till förmån för den tilltalade fungerar som funktion i Sverige och Norge. Den syftar vidare till att, med en komparativ metod, utreda funktionerna i respektive land och analysera vad Sverige kan lära sig utifrån de skillnader som finns i Norge. I ett uppmärksammat mål i Sverige förra året blev en person beviljad resning efter tredje försöket för attThis thesis explores how criminal cases can, in the light of new evidence, be reviewed in benefit of convicted defendants in both Sweden and Norway. The purpose is to describe the functionality of reviews in both countries, to compare the two and to analyze what Sweden can learn from the differences presented in Norway. In a prominent case last year in Sweden, a person was granted review after hi

Caroline Arvaker Utan naturen kan vi inte leva I naturen finns alla våra resurser vilket gör den viktig att skydda. Detta är en gemensam värdering hos ett antal unga utomeuropéer boende i Malmö. Dock leder inte pro naturella värderingar alltid till ett miljöengagemang i handling, det finns andra faktorer som spelar in. I mitt masterarbete har jag genom intervjuer undersökt hur tio utomeuropéer ABSTRACT The purpose of this study is to examine how young adults with non-European background and with an upbringing in a city associate to nature and what may have influenced these associations. Given that a majority of people live in cities, there is a risk that many young people do not spend time in natural environments, which may affect their associations to nature and also their environment

Dagens belysning i många hem världen runt består till stor del av vanliga glödlampor. I många svenska och västerländska hem är det även vanligt med låg-energilampor och fosfor-LEDs. Fosfor är ett grundämne som tillsammans med blåa LEDs möjliggör skapandet av vitt ljus. Principen bygger på att blått LED-ljus passerar ett fosforlager där en del av det blåa ljuset omvandlas till gult ljus. KombinatioThis literature review investigates and evaluates different strategies to improve InGaN-based light emitting diodes (LED) by analyzing published theoretical and experimental studies. The issues of non-uniform carrier distribution, piezoelectric polarization fields and poor wave function overlap can be mitigated by the use of InGaN barriers and substrates as well as staircase designs for quantum we

In this study we have explored managers’ perceptions of the importance of Corporate Social Responsibility (CSR), and the extent to which CSR can be evaluated and promoted through third-party certifications. To understand how such certifications affect companies and their corporate governance, we have explored the Icelandic Equal Pay Certification (EPC), an example of a CSR initiative. Using ten qu

The concept of sustainable development has been widely spread and practiced within urban planning. However there is no easy answer to how to define and create social sustainability. Therefore four categories that indicate social sustainability have been used to study the phenomenon. These are: Safety Meeting places Participation in the planning process Green areas The purpose of this study is to e

Pulver används inom många moment i läkemedelsbranschen, däribland tillverkning av tabletter och dylika processer. Att förstå och kunna anpassa sig till hur pulver beter sig, “flyter”, genom till exempel en tabletteringsmaskin leder till ökad kontroll över tabletternas innehåll och minskad variation mellan individuella tabletter. Vi kallar denna egenskap hos pulvers för deras “flytbarhet”. I vardagPowders are widely used in pharmaceutical applications and understanding their nature is an important aspect of making successful formulations. Powder flowability describes the behaviour of powders and can be measured using several different methods. This study looks at the techniques: angle of repose and tapped density, comparing them to each other and looking at how consistent they are with chan

This project aims to implement polarisation microscopy on the Tegenfeldt STED (stimulated emission depletion) microscope. STED microscopy is a targeted optical super-resolution method that can attain sub-diffraction resolution using visible light. This is now complemented with polarisation microscopy, which can measure the orientation of a fluorophore and, by extension, the molecule it is bound to

This thesis has two aims. One is to situate COVID-19 in a macro narrative that characterizes our time as a risk society or reflexive modernization. The other is to bring public health emergencies such as the COVID-19 pandemic into the sharp focus of cultural trauma study which is closely related to media representations. The research scope is set in media and communication studies. Through the the

Knowledge about how the Government governs its agencies is important to ensure legitimacy of the public exercise of power, and to further develop governing methods suitable for diverse types of agencies. This study focuses on a type of agency that is perceived as particularly difficult to govern – the university. The purpose is to describe how and to what extent the Government has attempted to gov
