Modelling of induction hardening in low alloy steels

Induction hardening is a useful method for improving resistance to surface indentation, fatigue and wear that is favoured in comparison with through hardening, which may lack necessary toughness. The process itself involves fast heating by induction with subsequent quenching, creating a martensitic layer at the surface of the workpiece. In the present work, we demonstrate how to simulate the proce

On the malleability of fairness ideals : Spillover effects in partial and impartial allocation tasks

How malleable are people's fairness ideals? Although fairness is an oft-invoked concept in allocation situations, it is still unclear whether and to what extent people's allocations reflect their fairness ideals. We investigate in a laboratory experiment whether people's fairness ideals are sensitive to spillover effects associated with the specific order of allocation tasks. Participants first ge

Applicant ethnicity affects which questions are asked in a job interview : The role of expected fit

Three experiments on professional recruiters explored how applicants' ethnicity affects questions prepared for a job interview and the implications of this. Study 1 revealed that outgroup applicants prompt recruiters to focus more on whether applicants have integrated cultural norms and values fitting the ingroup norms (person-culture fit), as well as the match between the applicants and their wou

A cross-country comparison of accommodation manager perspectives on online review manipulation

Accommodation businesses are increasingly dependent on a limited number of reservation platforms. A significant feature of these platforms is guest evaluations, which are transformed into ratings and rankings. As the positioning of the business in comparison to competitors determines customer demand, accommodation managers have considerable interest in maintaining or improving their online reputat

Water in Kazakhstan, a key in Central Asian water management

Central Asia is one of the regions with the highest probability of conflicts over water. Kazakhstan is the main Central Asian economic power and therefore it is important to understand how the country’s water management policy is influencing water availability in the other Central Asian states. Already, the Central Asian economies are developing under increasing water deficiency, resulting in deve

The influence of pH and divalent/monovalent cations on the internal electron transfer (IET), enzymatic activity, and structure of fructose dehydrogenase

We report on the influence of pH and monovalent/divalent cations on the catalytic current response, internal electron transfer (IET), and structure of fructose dehydrogenase (FDH) by using amperometry, spectrophotometry, and circular dichroism (CD). Amperometric measurements were performed on graphite electrodes, onto which FDH was adsorbed and the effect on the response current to fructose was in

Chemical Shifts of the Carbohydrate Binding Domain of Galectin-3 from Magic Angle Spinning NMR and Hybrid Quantum Mechanics/Molecular Mechanics Calculations

Magic angle spinning NMR spectroscopy is uniquely suited to probe the structure and dynamics of insoluble proteins and protein assemblies at atomic resolution, with NMR chemical shifts containing rich information about biomolecular structure. Access to this information, however, is problematic, since accurate quantum mechanical calculation of chemical shifts in proteins remains challenging, partic

How Dark Are Radial Breathing Modes in Plasmonic Nanodisks?

Due to a vanishing dipole moment, radial breathing modes in small flat plasmonic nanoparticles do not couple to light and have to be probed with a near-field source, as in electron energy loss spectroscopy (EELS). With increasing particle size, retardation gives rise to light coupling, enabling probing breathing modes optically or by cathodoluminescence (CL). Here, we investigate single silver nan

Experimental validation of a thermal model for high speed switched reluctance machines for traction application

This article presents the experimental validation of a novel cooling concept applied to a high speed switched reluctance machine topology for traction applications. By circulating the coolant in between the coils and the stator poles the winding and the stator iron are virtually thermally decoupled. A number of test motorettes are used to demonstrate the potential of the cooling concept at current

An Efficient Algorithm for Matrix-Valued and Vector-Valued Optimal Mass Transport

We present an efficient algorithm for recent generalizations of optimal mass transport theory to matrix-valued and vector-valued densities. These generalizations lead to several applications including diffusion tensor imaging, color image processing, and multi-modality imaging. The algorithm is based on sequential quadratic programming. By approximating the Hessian of the cost and solving each ite

Welcome to Hipsterville, In search of urban sustainable tourism.

Hipsterville has many locations, primarily in Europe and North America. The name of this ”place” refers tourban districts, mainly in large cities, which are dominated by particular subcultures. They are often formerworking class districts, in different stages of gentrification, located away from traditional tourism disticts. Inthese districts, clusters of small scale innovative firms may develop,

Ergonomic factors and musculoskeletal pain in sonographers

Background: Sonographers have a high risk of musculoskeletal disorders. Sonography involves strenuous postures in the neck and upper limbs, and is visually demanding. Echocardiography is especially challenging, with static postures and monotonous movements. Aim: The overall aim of this thesis was to identify ergonomic risk factors for pain in sonographers, and to propose actions for sustainable woBackground: Sonographers have a high risk of musculoskeletal disorders.

Why should we teach tourism at universities?

Why should we teach tourism at universities?This presentation targets the question of why tourism should be part of university education. Presently, this is questioned by colleagues in traditional academic disciplines as well as by parts of the tourism industry, which are somewhat reluctant to employ people with a university degree. It is thus time for this matter to be raised. If we are to answer

The non-haemostatic role of platelets in systemic lupus erythematosus

Dysregulation of lymphocyte function, accumulation of autoantibodies and defective clearance of circulating immune complexes and apoptotic cells are hallmarks of systemic lupus erythematosus (SLE). Moreover, it is now evident that an intricate interplay between the adaptive and innate immune systems contributes to the pathogenesis of SLE, ultimately resulting in chronic inflammation and organ dama

Implementation and use of finance information system: Results of a field study in Ugandan Universities

Benefits arising from the use of finance information systems that include among others capability to offer improved timely and reliable accounts reports have been mentioned by many different scholars. The issue of successfully implementing and using the systems is however still a challenging problem especially in developing countries. A lot of critical success factors for implementation have been

Reshaping Boundaries: Family Politics and GLBTQ Resistance in Urban Vietnam

Journal of GLBT Family StudiesAlthough Vietnamese society is currently undergoing significant changes with regards to the rights and perceptions of gay, lesbian, bisexual, transgender, and queer (GLBTQ) people, dominant socio-cultural norms related to gender, sexuality, and the importance of the patrilineal family regime continue to cast a shadow over the lives of GLBTQ in contemporary Vietnam. Based on ethnographic fieldwork
