□ Total hip arthroplasty (THA) registers are established in several countries to collect data aiming to improve the results after THA. Monitoring of adverse outcomes after THA has focused mainly on revision surgery, but patientreported outcomes have also been investigated. □ Several surgery-related factors influencing the survival of the THA have been thoroughly investigated and have changed clini
This case study on the dark side of communication and place branding explores the Amazon corporation’s highly-publicized competitive search for a city to become their second headquarters (dubbed HQ2). In 2017 Amazon sent an open Request for Proposals (RFP) to cities in North America defining what constitutes an ‘ideal’ headquarters. In addition to offering capital and incentives, Amazon’s ideal ci
The resurgence of artificial intelligence (AI) has empowered organizations to concentrate their research efforts on enhancing decision-making and automation capabilities. This is being pursued with the goal of increasing productivity, whilst reducing costs. With this, it is perceived that the jobs within these organizations that are considered subject to ‘routine’, or repetitive and mundane tasks,
The Advanced Light Source (ALS) at Berkeley Lab has seen many upgrades over the years, keeping it one of the brightest sources for soft x-rays worldwide. Recent developments in magnet and vacuum technology, as well as lattice design (multi bend achromat lattices) appear to open the door for very large further increases in brightness [1]. This could be achieved by reducing the horizontal emittance,
The intensification of agricultural practices throughout the twentieth century has had large detrimental effects on biodiversity and these are likely to increase as the human population rises, with consequent pressure on land. To offset these negative impacts, agri-environment schemes have been widely implemented, offering financial incentives for land-owners to create or maintain favourable habit
The pancreatic islets in obese-hyperglycemic mice display a normal response of insulin secretion when stimulated with glucose in vitro. This indicates that the impaired glucose metabolism is due to extra-pancreatic factors rather than to deficient β-cell function. In fact, the pancreas of these mice is a useful source from which to isolate large numbers of mammalian β-cells suitable for studies of
Purpose: The purpose of this paper is to elaborate on how perspectives and assumptions embedded in the complexity paradigm contribute to make logistics management research better aligned with real-life logistics. This is necessary, due to increasing supply chain complexity caused by an increasing request for sustainable development (SD). Design/methodology/approach: The research is exploratory and
The minimum weighted edge dominating set problem (MWEDS) generalizes both the weighted vertex cover problem and the problem of covering the edges of graph by a minimum cost set of both vertices and edges. In this paper, we propose a meta heuristic approach based on genetic algorithm and local search to solve the MWEDS problem. Therefore, the proposed method is considered as a memetic search algori
Lawrence Summers produced a big upset within the economics profession when he revived Alvin Hansen’s theory of secular stagnation, which had been thought of as an old-Keynesian fallacy. While some economists like Brad DeLong and Paul Krugman instantly recognized Summers’s contribution, a large share of the economics profession remained skeptical at first. Whereas most New Keynesian models allow fo
We live an increasingly larger part of our lives online. The Internet has fundamentally changed how we find information, buy products, connect with friends and find entertainment such as video streaming and digital distribution of books. The Internet has changed the competitive landscape for many markets. Local sellers suddenly face competition from sellers around the globe, introducing more choic
Antioxidants are compounds present in plant, fruit, and vegetables, and they are known for their medicinal benefits such as anti-carcinogenic and anti-fungicidal activity. Most commonly used methods for extractions of such compounds are lengthy due to mass transfer limitations. This study proposes the use of carbon-dioxide expanded liquids (CXLs) as solvent to improve these limitations. Such solve
Soft biological tissues and engineered hydrogels for biomedical applications are intrinsically multiphasic materials, consisting of solid, fluid and possibly fixed and mobile ions. Understanding their mechanical behaviour requires experimental methods and theoretical models that take their multiphasic nature into account and allow for quantification of material parameters related to the different
This Bachelor thesis aims to analyze and clarify the situation of the irregular migrants in United Kingdom, whether it´s changing when applying UK:s own migrant legislation; The UK Immigration Act 2014, compared to EU:s migration policy and legislation. Based on Hannah Arendts theory on the irregular migrants loses their right to have rights, when migrating from their original country. These peopl
Parkinson’s disease (PD) is a highly heterogenous disorder characterized by bradykinesia, rigidity, rest tremor and non-motor symptoms like cognitive impairment, anosmia, and sleep disturbance. The underlying pathological hallmarks of PD are the degeneration of dopaminergic pigmented neurons in the substantia nigra pars compacta, neuroinflammation and, alpha synuclein inclusions accumulating into
This master thesis has investigated if flow cytometry can be used to monitor bathing water quality on the beaches in Southern Sweden. The current method for monitoring the bathing water quality takes 3 days to get results about the concentrations of fecal indicator bacteria, E.coli and intestinal enterococci, and to get answers if the water is usable or unusable for swimming. These bacteria serve
Single cell gene expression assays have become a powerful tool with which to dissect heterogeneous populations. While methods and software exist to interrogate such data, what has been lacking is a unified solution combining analysis and visualisation which is also accessible and intuitive for use by non-bioinformaticians, as well as bioinformaticians.
Features below the first conductance plateau in ballistic quantum point contacts (QPCs) are often ascribed to electron interaction and spin effects within the single mode limit. In QPCs with a highly asymmetric geometry, we observe sharp resonance peaks when the point contacts are gated to the single mode regime, and surprisingly, under certain gating conditions, a complete destruction of the 2e(2
We study the dynamic admission control for a finite shared buffer with support of multiclass traffic under Markovian assumptions. The problem is often referred to as buffer sharing in the literature. From the linear programming (LP) formulation of the continuous-time Markov decision process (MDP), we construct a hierarchy of increasingly stronger LP relaxations where the hierarchy levels equal the
