The concern of this paper is with the mediatisation of tourism cities through fast circulating narratives on digital platforms in an era characterised as post-truth involving the spread of fake news and disinformation. Hence far, there is scarce knowledge on how misleading information and false rumours concerning terrorism affect the image of tourism cities. In addition, extant research studies pr
Existing oculoplastic reconstructive surgical techniques are based on empirical knowledge and were established long before perfusion monitoring was possible. It is believed that an avascular graft should always be placed on a vascular bed or flap and also that the viable length of a flap depends on the width of its pedicle. The actual role of the length, width and thickness of a random flap in its
Borehole thermal resistance is both an important design parameter and a key performance characteristic of a ground heat exchanger. Another quantity that is particularly important for ground heat exchangers is the internal thermal resistance between the heat exchanger pipes. Both these resistances can be calculated to a high degree of accuracy by means of the well-known multipole method. However, t
Computerised tomography and magnetic resonance tomography were performed in nine faecally incontinent patients more than eight years after rectoplasty for high imperforate anus. No statistically significant correlation was found between function, i. e. degree of faecal incontinence, and anatomical findings. Thus, in spite of a detailed demonstration of the post-operative anatomy, the information d
Most genome sequencing projects using intracellular bacteria face difficulties in obtaining sufficient bacterial DNA free of host contamination. We have developed a simple and rapid protocol to isolate endosymbiont DNA virtually free from fly and mosquito host DNA. We purified DNA from six Wolbachia strains in preparation for genome sequencing using this method, and achieved up to 97% pure Wolbach
The xyn1 encoded 5 domain xylanase from the thermophilic bacterium Rhodothermus marinus binds specifically to xylan, β-glucan and amorphous but not crystalline cellulose. Our results show that the binding is mediated by the full length xylanase, but not by the catalytic domain only. Based on similarities concerning both predicted secondary structure and binding specificity found with one cellulose
Green packaging development (GPD) involves the process of developing packaging with minimized environmental impact. Over the last decade, the GPD perspective has evolved from a traditionally packaging material-focused one to a holistic one. A holistic perspective on GPD means that the different environmental requirements on packaging have to be combined so that the overall environmental impact of
Bacteria utilize complement regulators as a means of evading the host immune response. Here, we describe protocols for evaluating the role vitronectin acquisition at the bacterial cell surface plays in resistance to the host immune system. Flow cytometry experiments identified human plasma vitronectin as a ligand for the bacterial receptor outer membrane protein H of Haemophilus influenzae type f.
Partially premixed combustion (PPC) in internal combustion engine as a low temperature combustion strategy has shown great potential to achieve high thermodynamic efficiency. Methanol due to its unique properties is considered as a preferable PPC engine fuel. The injection timing to achieve methanol PPC conditions should be set very close to TDC, allowing to utilize spray-bowl interaction to furth
Biodegradable patches made from polyhydroxybutyrate (PHB) were used to close experimentally induced atrial septal defect in six calves. The implants were evaluated after 3-12 months macroscopically and by light and scanning electron microscopy with regard to regeneration of tissue and degradation of the polymer. At implant degradation, complete endothelial layers facing the right and left atrium w
Synthetic and natural polymeric esters find applications in transport and construction sectors, where fire safety is an important concern. One polymer that is widely used is poly (methyl methacrylate) (PMMA), which almost completely undergoes thermal decomposition into methyl methacrylate (its monomer) CH2=C(CH3) - C(= O) - O - CH3 (MMA) at ~250–300°C. In order to analyze the high-temperature gas-
The parabolic equation is approximated by a set of ordinary differential equations and by finite difference equations. special attention is given to the approximation of the boundary condition. Some identities suitable to check numerical calculations are also derived.
The properties of combined multiplier and penalty function methods are investigated using a second-order expansion and results known for the Riccati equation. It is shown that the lower bound of the values of the penalty constant necessary to obtain a minimum is given by a certain Riccati equation. The convergence rate of a common updating rule for the multipliers is shown to be linear.
Background: The aims of this study were to establish the diagnostic accuracy of the European Cross-Cultural Neuropsychological Test Battery (CNTB) for dementia in different ethnic populations in Western Europe, to examine its ability to differentiate cognitive impairment profiles for dementia subtypes, and to assess the impact of demographic variables on diagnostic properties. Methods: The study w
Purpose: This paper aims to explore how the ownership transfer from a highly industrialised country to less industrialised countries influences consumers’ brand perceptions. Design/methodology/approach: Three acquisition cases of premium car brands (Jaguar, Land Rover and Volvo) are investigated using qualitative data from online brand communities. Findings: When country of ownership (COOW) for br
