The applicability of using flat composite plates and hollow core composite cylinders for moisture absorption testing of unidirectional glass/polymer composites used in high voltage composite (non-ceramic) insulators was examined. Two main issues were addressed in this work. First, the effect of specimen geometry (cylinders vs. plates) on moisture absorption by the composites was investigated both
Rainfall is a primary factor for agricultural production, especially in a rainfed agricultural region. Its accurate prediction is therefore vital for planning and managing farmers’ plantations. Rainfall plays an important role in the symmetry of the water cycle, and many hydrological models use rainfall as one of their components. This paper aimed to investigate the applicability of six machine le
The concept of direct membrane filtration (DMF) is relatively new for treating municipal wastewater. In contrast to a conventional membrane bioreactor, DMF decouples filtration and biological treatment. This presentation is based on a pilot scale DMF study conducted at the municipal wastewater treatment plant in Svedala (Sweden), combined with lab-scale experiments and analysis to optimise the pil
A palynological investigation has been conducted on Lower-Upper Miocene sediments from Jylland, Denmark, corresponding to the time interval of about 19 to 8 Ma. The sediments, derived from the Sdr. Vium drill core, were deposited in marine to marginal-marine environments, as shown by the relatively high abundance of dinoflagellate cysts in all samples. Nevertheless, rich and diverse pollen assembl
Aims/hypothesis There has been long-standing debate about whether diabetes is a causal risk factor for pancreatic cancer or a consequence of tumour development. Prospective epidemiological studies have shown variable relationships between pancreatic cancer risk and blood markers of glucose and insulin metabolism, overall and as a function of lag times between marker measurements (blood donation) a
Cardiac resynchronization Therapy (CRT) with or without a defibrillator has a positive effect on mortality and morbidity for patients with heart failure. However, comparisons between CRT-Defibrillators (CRT-D) and CRT-Pacemakers (CRT-P) are relatively scarce outside the clinical trial setting. This study aimed to assess baseline characteristics in relation to long-term prognosis in patients treate
It is a well-known fact that in any Application Specific Integrated Circuit (ASIC) design, verification consumes most time and resources. And when it comes to huge designs, finding bugs can be tedious given the area and the complexity. As per Moore’s law, the design complexity is increasing exponentially due to the growing demand for performance. Therefore, On-Chip communication becomes crucial. T
Market and policy pressures increasingly demand a shift towards sustainable means of production; thereby, the inconclusive and long-standing debate between the impact of environmental efforts and economic performance at the firm level has never been so relevant. However, companies who seek to prioritize sustainability on their processes and outputs still need to focus on their financial returns.
III-V semiconductors are a profound part of the optoelectronics industry and new developments in alloy compositions and architectures are constantly emerging. Lowdimensional semiconductors, such as nanowires (NWs) have shown to have improved characteristics in certain areas such as enhanced light absorption and can furthermore be integrated on Silicon (Si) plattforms and are thus predicted to be a
This thesis explores how business angels’ (BA’s) human- and financial capital contribute to the early-stage development of start-ups. While previous literature has extensively discussed BAs' financial roles, the combined effect of both capital types, particularly in relation to relational trust, remains underexplored. Addressing this gap, the study applies a qualitative approach, interviewing
This research aims to contribute to the field of crisis communication conducted within the specific context of a non-governmental organization (NGO). Focus is put on investigating the perceived strategies for crisis communication that the Swedish Red Cross made use of during its crisis in 2009 and 2010 as well as a ten-year media representation of the issue. The empirical material consists of inte
This thesis examines the impact of the objects that surrounds us and the practices of consumption in which we engage on the cultural constructions we live and vice versa taking its point of departure in an examination of the objects and consumption practices that have been used in the definition of the construct of modernity in various cultures. Theoretically it develops a framework based on speec
Natural gas has been traditionally applied in spark-ignited combustion engines due to similar combustion characteristics for methane gas and gasoline. However, spark ignition requires a low compression ratio to avoid knock problems and therefore, gas engines have lower efficiency than diesel engines. A combustion concept that has been successfully applied on large stationary engines and to some ex
In Brazil, the northeastern region (NEB) is considered one of the most vulnerable areas of the country in terms of precipitation variability due to frequent drought episodes during the rainy season. Differently from the Northern NEB (NNEB), where dry season is consistently dry, the Eastern NEB (ENEB) exhibits a high interannual variability of precipitation during the dry season, including years ex
IntroductionHaemophilia is a X-linked bleeding disorder affecting mostly males. Women are mainly carriers ofhaemophilia, however, they can expereince high bleeding tendency and assocaited symptoms aswith males. In the absence of the appropriate treatment, bleedings, especially into the joints, result inadverse outcomes. The general aim of this thesis was to promote the use of register-based data t
Marine endotherms in the polar regions face a formidable thermal challenge when swimming in cold water. Hence, they use morphological (fat, blubber) adjustment and peripheral vasoconstriction to reduce demands for heat production in water. The animals then regain normothermia when resting ashore. In the king penguin (Aptenodytes patagonicus) metabolic rate is lower in fed than in fasted individual
This research examines the practices of consumers that are made possible by a 'low-end' street, and how these shopping practices in turn shape and maintain a high street at the urban margins. It locates itself within the academic inquiries of cultural geographies of retail.Södergatan is the field of the study, the main shopping street in the stigmatized southern part of city of Helsingborg in Swed
The aims of the thesis are to investigate the estimation power and the normality of standardized residuals for Generalized autoregressive conditional heteroscedasticity models (GARCH). We facilitate the analysis by only dealing with GARCH(1, 1) models. We take use of MATLAB as the statistical programming tool for the simulation of the data and the estimation. We define the meaning of estimation
