Surfactants have been the basis for applications in several industrial sectors for a long time. However, fundamental research was 50 years ago still limited to a small number of academic groups and even basic aspects were controversial. The field has since undergone an enormous expansion and the improved understanding has laid the basis of numerous new products as well as been the basis of importa
A range of interesting electromagnetic systems like antennas, extraordinary transmission and absorbers have been shown to have certain bandwidth limitations given by a family of sum-rules. Common for the systems are that they are passive, linear and time-translational invariant. In this paper we shortly review the extension from one-dimensional passive systems to multi-dimensional systems, aiming
Governance of common resources such as water calls for rethinking structure, legal frameworks and property rights. In order to promote the decentralization of water governance, Water User Associations (WUAs) were created in many countries, such as India and Turkey, to operate and maintain irrigation systems as well as take over the responsibility of water distribution among water users. Despite pr
This paper considers off-line optimization of a switching sequence fora given finite set of linear control systems and joint optimization ofcontrol laws. A linear quadratic full information criterion isoptimized and dynamic programming is used to find the optimalswitching sequence and control laws. The main result is a method for efficient pruning of the search tree to avoid combinatoric explosion
We obtained 10/192 and 3/384 antibody-secreting hybrids after immunization of Balb/c mice with either human growth hormone or affinity-purified rabbit anti-(human growth hormone) respectively. Radiolabelled rabbit anti-(human growth hormone) antibodies, but not human growth hormone, were specifically bound by supernatants from the 13 hybrids. The binding was completely inhibited by human-growth-ho
New therapies, based on gene transfer and protein delivery, require a better understanding of the basic mechanisms of macromolecular membrane transport. We have studied cellular uptake of macromolecular polyanions, i.e. DNA and glycosaminoglycans, and a polybasic HIV-Tat derived peptide (GRKKRRQRRRPPQC), using fluorescence assisted cell sorting and confocal fluorescence microscopy. The Tat peptide
The heat conduction in a two-dimensional square plate at nano/micro scales is investigated using numerical and semi-analytical methodologies which are energy conserving dissipative particle dynamics (DPDe) and Boltzmann transport equation (BTE) with the gray relaxation time approximation. The solution domain was considered to be a two-dimensional square plate surrounded by walls having constant te
The present study aimed to investigate the relationship between growth rate, final mass, and larval development, as well as how this relationship influences reproductive trade-offs, in the context of a gregarious life-style and the need to keep an optimal group size. We use as a model two sympatric populations of the pine processionary moth Thaumetopoea pityocampa, which occur in different seasons
Quenching of photoluminescence in a substituted polythiophene in the presence of a deposited C-60 layer is studied by steady-state and time-resolved photoluminescence (PL). The steady-state PL is evaluated by con -sidering the interference of the absorbed and emitted electro-optical field in the thin film coupled to exciton diffusion in the conjugated polymer. PL quenching occurs for excitons gene
Background: Early hospital arrival and rapid intervention for acute myocardial infarction is essential for a successful outcome. Several studies have been unable to identify explanatory factors that slowed decision time. The present study examines whether personality, psychosocial factors, and coping strategies might explain differences in time delay from onset of symptoms of acute myocardial infa
Background: The aim of this study was to explore if a course consisting of lectures combined with simulator training in coronary angiography (CA) could accelerate the early learning curve when performing CA on patients. Knowledge in performing CA is included in the curriculum for the general cardiologist. The method, according to American College of Cardiology and European Society of Cardiology gu
Uppsatsen analyserar samspelet mellan rätten till dataportabilitet enligt EU:s dataskyddsförordning (GDPR) med skyddet för företagshemligheter enligt företagshemlighetsdirektivet. Syftet är att undersöka hur dess två regelverk påverkar varandra och hur en balans kan uppnås mellan individens rätt till sin data och företagens behov av att skydda känslig information. Uppsatsen klargör vad rätten tillThe thesis analyzes the interplay between the right to data portability under the EU General Data Protection Regulation (GDPR) and the protection of trade secrets under the Trade Secrets Directive. The aim is to examine how these two frameworks interact with each other and how a balance can be achieved between an individual's right to their data and the need for businesses to protect sensitive
Med en ökad internationell handel krävs i större omfattning trygga säkerheter för borgenärer. Vanliga sådana är äganderättsförbehåll och säkerhetsöverlåtelser som används frekvent internationellt. Uppsatsens syfte är att utreda dessa säkerhetsrätter med avseende på den svenska internationella privaträtten. För att utreda detta används en praxis- och doktrininriktad rättsdogmatisk metod. Det konstWith a growing international trade globally, the demand for collateral for creditors increases. Non-possessory security interests, more specifically conditional sales with reservation of title by the seller and security transfers of ownership are commonly used internationally. The purpose of this essay is to investigate what these non-possessory security interests mean in relation to Swedish priva
Läkemedelsmarknaden är uppbyggd runt företag, så kallade originalföretag, som utvecklar nya läkemedel och patenterar dessa. Patent är viktigt eftersom det ger originalföretagen en tidsbegränsad monopolistisk marknadsställning. De har därigenom möjlighet att genom stora marknadsvinster få tillbaka investeringarna som gjorts för att ta fram nya läkemedel. Patent ger också incitament till fortsatt foThe pharmaceutical market is based on companies, called originators, who develop new drugs and patent them. Patents are important since they allow the originators a time-limited monopolistic market position. The originators then have the opportunity to enjoy significant market profits to cover the costs for the development of a new drug. Patents are also an incentive for continued research and dev
Patientlyftar och passiva lyftselar används när en person inte kan förflytta sig. Typiska förflyttningar sker från en säng eller rullstol till en hygienstol för att använda toalett eller dusch. Patientlyften styrs av vårdpersonal, ofta undersköterskor, och förflyttningarna är komplexa och en högriskuppgift inom vård och omsorg. Lyftselar har ofta långa remmar som fästs vid en lyft. När remmarna loPatient lifts and passive lifting slings are used when a person is unable to move. Typical patient transfers are from a bed or a wheelchair to a hygiene chair to use a toilet or shower. The patient lift is controlled by healthcare professionals, often assistant nurses, and the transfers are complex and a high-risk task within clinical care. Patient lifting slings often have long straps that attach
