An on-board measurement system has been developed that in real time identifies the probability for occurrence and also the exact location of severe wear in the wheelrail contact. Noise generated by the wheel-rail contact is a troublesome side effect both when railway vehicles negotiate curves and run on straight tracks. The concept behind this project is to use this noise as an indicator of the tr

The wheel-rail system operates in an open environment where the weather condition varies constantly. In this laboratory study, an investigation using a pin-on-disc tribometer placed in a temperature-controlled room was conducted to examine the effect of subzero temperature and snow on friction and wear at the wheel-rail contact. In temperature range from 3 to-15 °C (without snow) friction and wear

AbstractBackground: Non-communicable diseases are the number one killer worldwide and the leading one,cardiovascular disease (CVD), is responsible for more than 30% of all deaths. CVD is a progressive disease whichalso makes it economical, easy and effective to prevent. There are many stages of CVD that ultimately can lead tocoronary atherosclerosis, measurable as coronary artery calcification (CA

Traditional analyses of 1 Cor 14:20–25 have not been able to solve the interpretational problems, especially the crux interpretum of v. 22b. Since the problem is one of argumentation it is natural to seek assistance from a method of argumentation analysis. By making use of the method by Stephen Toulmin, it can be shown that the argument may contain more information than is directly apparent. By re

Gal 3:6–14 är ett av många avsnitt i Paulus brev som är svårt att förstå p.g.a. den komplicerade argumentationen. En argumentationsanalys är därför påkallad för att reda ut argumenten och för att klargöra eventuella implicita premisser. En sådan analys ger oss en bättre uppfattning av Paulus argumentation än en traditionell exeges ensam kan ge. Analysen ger vid handen att Paulus försöker övertyga

Through an argumentation analysis can one show how it is feasible to view a narrative religious text such as the Gospel of Matthew as a literary argument. The Gospel is not just “good news” but an elaborate argument for the standpoint that Jesus is the Son of God, the Messiah. It is shown why an argumentation analysis needs to be supplemented with a pragmatic literary analysis in order to describeThrough an argumentation analysis can one show how it is feasible to view a narrative religious text such as the Gospel of Matthew as a literary argument.

The article analyses techniques of verbal rhetoric based on recordings of prayer meetings from the first year of the Nokia Missio Church (2008–2009). The rhetorical situation is of particular interest in this charismatic congregation. The crowd can be examined from the viewpoint of the various participant groups, drawing on Lloyd Bitzer’s idea of the life span of a rhetorical situation. Classical

Even though the design of buildings and technologies have been mainly focused on reducing energy use, there is still a discrepancy between predicted and actual energy saving due to user behavior. There is a need of understanding the behavior and relevant factors of using energy-efficient solutions. Energy-efficient solutions in an indoor environment can be defined as building characteristics such

Clinical trials in neurodegenerative disorders have been associated with high rate of failures, while in oncology, the implementation of precision medicine and focus on genetically defined subtypes of disease and targets for drug development have seen an unprecedented success. With more than 20 genes associated with Parkinson’s disease (PD), most of which are highly penetrant and often cause early

Tuning the anisotropy through exchange bias in bimagnetic nanoparticles is an active research strategy for enhancing and tailoring the magnetic properties for a wide range of applications. Here we present a structural and magnetic characterization of unique FeCr-oxide nanoparticles generated from seed material with a Fe : Cr ratio of 4.71 : 1 using a physical aerosol method based on spark ablation

Background: Processing the surface electromyogram (sEMG) to decode movement intent is a promising approach for natural control of upper extremity prostheses. To this end, this paper introduces and evaluates a new framework which allows for simultaneous and proportional myoelectric control over multiple degrees of freedom (DoFs) in real-time. The framework uses multitask neural networks and domain-

Internally structured block copolymer-surfactant particles are formed when the complex salts of ionic-neutral block copolymers neutralized by surfactant counterions are dispersed in aqueous media. Here, we report the1H NMR signal intensities and self-diffusion coefficients (D, from pulsed field gradient nuclear magnetic resonance, PFG NMR) of trimethyl alkylammonium surfac-tant ions and the poly(a

Little is known about the extent of variation and activity of naturally occurring milk glycosidases and their potential to degrade milk glycans. A multi-omics approach was used to investigate the relationship between glycosidases and important bioactive compounds such as free oligo-saccharides and O-linked glycans in bovine milk. Using 4-methylumbelliferone (4-MU) assays activities of eight indige

Human rely profoundly on tactile feedback from fingertips to interact with the environment, whereas most hand prostheses used in clinics provide no tactile feedback. In this study we demonstrate the feasibility to use a tactile display glove that can be worn by a unilateral hand amputee on the remaining healthy hand to display tactile feedback from a hand prosthesis. The main benefit is that users

Since the turn of the century, agriculture in sub-Saharan Africa has been undergoing rapid transformation. Ghana is experiencing an agrarian revolution with increasing farmland sizes, increased mechanisation of production and external input usage, and high levels of commercialisation. In this paper we show the growth of farm sizes, the major drivers of increasing farm sizes, and emerging relations

Extracts of Diprion similis females contained about 15 ng of the sex pheromone precursor 3,7‐dimethylpentadecan‐2‐ol per female. After derivatisation with (S)‐2‐acetoxypropanoyl chloride, we found that the major stereoisomer in the extract was (2S,3R,7R)‐3,7‐dimethylpentadecan‐2‐ol. Small amounts of other stereoisomers of 3,7‐dimethylpentadecan‐2‐ol were also identified in the extract, namely 1% o

Pregnancy may influence cellular immune responses to Mycobacterium tuberculosis. We investigated M. tuberculosis-specific interferon-g responses in women followed longitudinally during pregnancy and postpartum. Interferon-g levels (stimulated by M. tuberculosis antigens [TB1 and TB2] and mitogen included in the QuantiFERON-TB Gold Plus assay) were measured in blood from pregnant HIV-negative women
