This paper presents a convex optimization approach to study optimal realizations of passive electromagnetic structures. The optimization approach complements recently developed theory and techniques to derive sum rules and physical limitations for passive systems operating over a given bandwidth. The sum rules are based solely on the analytical properties of the corresponding Herglotz functions. H
Abstract in Undetermined Regional Aesthetics: Locating Swedish Media maps more than two hundred years of Swedish media. It ranges from written travelogues in the eighteenth and nineteenth centuries via feature films, documentaries, TV programmes, literature and press to contemporary video activism on the Internet. The nineteen contributors navigate the reader through a variety of media landscapes
Popular Abstract in Swedish Åderförkalkning, den i folkmun använda benämningen för ateroskleros, är en sjukdom som de flesta lider av. Vi vet bara inte om det. Ateroskleros ger nämligen sällan symptom innan ett aterosklerotiskt plack (en lokal aterosklerosansamling i kärlväggen) brister och det bildas en blodpropp. Om placket som brister sitter i kärlen som förser hjärtat eller hjärnan med blod kaMyocardial infarction and stroke, mainly caused by a rupture of an atherosclerotic plaque, are two of the most common causes of mortality and morbidity in the world. Previous studies have pointed out inflammation, driven by inflammatory lipids, as the keystone in the formation of the rupture prone vulnerable plaque. The risk for a plaque rupture is greatly enhanced in the diabetic population and i
Abnormalities within a limited number of small and medium enterprises (SMEs) in Australia are reported. A set of interrelated industrial issues are brought out in order to advance the state of knowledge and avoid similar abnormalities / irregularities and to bring back some ideas for the mitigations. Impacts on new automated systems and on industrial as well as safety standards are expected in the
As the work of the IWA Task Group on Benchmarking of Control Strategies for wastewater treatment plants (WWTPs) is coming to an end, it is essential to disseminate the knowledge gained. For this reason, all authors of the IWA Scientific and Technical Report on benchmarking have come together to provide their insights, highlighting areas where knowledge may still be deficient and where new opportun
Hydrolysis constants of mixed sludge at 35°C, 55°C, and 60°C were found to be 0.32 d-1, 0.44 d-1, and 0.50 d-1, respectively in pilot-scale semi-continuously operated anaerobic digesters. The hydrolysis constants as well as estimated chemical oxygen demand (COD) fractions in the feed were introduced to a mathematical model for anaerobic digestion published by Siegrist et al. (2002) which is simila
The production of biogas from six agricultural crops was analysed regarding energy efficiency and greenhouse gas (GHG) performance for vehicle fuel from a field-to-tank perspective, with focus on critical parameters and on calculation methods. The energy efficiency varied from 35% to 44%, expressed as primary energy input per energy unit vehicle gas produced. The GHG reduction varied from 70% to 1
Föreliggande avhandling består av fyra studier där det övergripande syftet med studierna var att utveckla ett mätinstrument för att bedöma vårdbehov och tidsåtgång relaterat till vilka personella resurser som krävs för att tillgodose aktuellt vårdbehov hos äldre boende på särskilda boenden inom kommunal äldreomsorg. Instrumentet har fått namnet Time in Care (TiC) och är uppdelat i två delar: Time
Abstract in UndeterminedIn this article we describe Professor, a new program for tuning model parameters of Monte Carlo event generators to experimental data by parameterising the per-bin generator response to parameter variations and numerically optimising the parameterised behaviour. Simulated experimental analysis data is obtained using the Rivet analysis toolkit. This paper presents the Profes
A late Holocene diatom stratigraphy of Bottom Pond (37050S, 12 70W) was studied and interpreted to infer paleolimnological and climate changes on Tristan da Cunha, South Atlantic. The diatom flora of Bottom Pond is dominated by meroplanktonic Aulacoseira alpigena and A. distans and a benthic/epiphytic flora including Achnanthes spp., Naviculadicta spp., Eunotia taxa and Frustulia rhomboides. The f
Haemophilus influenzae is a human specific Gram-negative respiratory tract pathogen. Encapsulated H. influenzae strains exist in six different serotypes a-f, of which type b (Hib) is the most virulent. Hib is protected by the polysaccharide capsule when invading the blood circulaton and may cause diseases such as meningitis and epiglottitis. Non-encapsulated H. influenzae referred to as nontypeabl
We compare photoelectron spectra (PES) and theoretical densities-of-states of C-60/Al(111), C-60/Al(110) and C-60/Al(100). The splitting observed on all three surfaces is attributed to final state charging. This splitting can also be used to improve estimates of the charging energy U of adsorbed molecules and as a criterion for the existence of strong covalent bonding to the electrode. Au exhibits
Transposition of intestinal segments is frequently used for bladder reconstruction. Following transposition, bowel segments continue to produce mucus and a correlation between excessive mucus production and complications such as urinary tract infection or catheter blockage has been observed for a long time. However, no information is currently available on the change of mucin expression and glycos
The field of vertical nanowire array-based applications in cell biology is growing rapidly and an increasing number of applications are being explored. These applications almost invariably rely on the physical properties of the nanowire arrays, creating a need for a better understanding of how their physical properties affect cell behaviour. Here, we investigate the effects of nanowire density on
Popular Abstract in Swedish Att arbete med barn som brottsoffer – en rättssociologisk studie Barn som utsätt's för brott utgör en grupp i vårt samhälle som i många situationer är beroende av företrädare för att få den hjälp och behandlig som de kan vara i behov av. I många fall är barnet's vårdnadshavare företrädare, men i vissa fall kan det vara vårdnadshavarna som utgör ett hot för barnet. I desThe thesis consists of three different purposes. Purpose number one entails describing and analysing the legal opportunities for, and the demands on, the work of the actors in question with regard to children as victims of crime. This purpose intends to illustrate the legal regulation, which in different ways, and to different degrees, controls the work of the actors. Whereas the legislation provi
Since the 1990’s representative democracy has been challenged by a deliberative turn in political philosophy, reaching even into the practices of established political institutions. In Sweden, the Municipality of Helsingborg, inspired by deliberative ideals, established civic committees as a way to deal with changing patterns of civic political behavior in late modernity. One reason for this is th
BACKGROUND: To explore the level of physical activity in a population based sample of older adults; to analyze the influence of pain characteristics and fear-avoidance beliefs as predictors of physical activity among older adults reporting chronic pain. METHODS: Demographics, pain characteristics (duration, intensity), physical activity, kinesiophobia (excessive fear of movement/(re) injury), se
Stroke is a leading cause of death and long-term neurological deficits worldwide, and no effective treatment is available for the vast majority of the stroke patients. A rapid and persistent activation of multiple and dynamic inflammatory and immune cascades, in and outside the brain, occurs after stroke. These cascades are believed to affect the progression of the cerebral damage, as well as neur
