The truths and falsehoods of post-truth leaders

Over the last three years, the idea of a ‘post-truth society’ has become a common talking point. Politicians from around the world, from Europe to South America to the United States, have been labelled as ‘post-truth leaders’, with Donald Trump being portrayed as the standard bearer for this new kind of political discourse. This article suggests that post-truth leadership is nothing new. Ever sinc

Fear of graft rejection after heart transplantation – a nationwide cross-sectional cohort study

Background: Cellular rejection is most common 3–6 months after heart transplantation while chronic rejection, that is, cardiac allograft vasculopathy and malignancy are the most common causes of death in heart-transplant recipients beyond the third year after transplantation. However, the heart transplantation recipient’s perceived threat of graft rejection has never been explored. Aim: The aim wa

Effect of wall conduction on the heat transfer characteristics of supercritical n-decane in a horizontal rectangular pipe for cooling of a scramjet combustor

Purpose: The purpose of this paper is to numerically study the influence of wall conduction on the heat transfer of supercritical n-decane in the active regenerative cooling channels. Design/methodology/approach: A horizontally placed rectangular pipe with a solid zone and another one without a solid zone were used. A drastic variation of thermo-physical properties was emphatically addressed. Afte

A Round Robin of fire modelling for performance-based design

Nine participants, representing eight different Swedish fire consultancy firms participated in a Round Robin study where two different cases were simulated with the Fire Dynamics Simulator. The first case included a large open warehouse where the activation of a sprinkler system was to be studied. In the second case time to critical conditions in a theatre was to be calculated. The participants we

Assessing the black box of feedback neglect in a digital educational game for elementary school

Background: Previous research shows that critical constructive feedback, that scaffolds students to improve on tasks, often remains untapped. The paper’s aim is to illuminate at what stages students provided with such feedback drop out of feedback processing. Methods: In our model, students can drop out at any of five stages of feedback processing: (1) noticing, (2) decoding, (3) making sense, (4)

Low-profile two-port MIMO terminal antenna for low LTE bands with wideband multimodal excitation

Multiple-input multiple-output (MIMO) is a key enabler for high data rates in mobile communications. However, it is challenging to design MIMO terminal antennas for LTE bands below 1 GHz, due to the conventional chassis offering only one resonant characteristic mode (CM). Recently, it was shown that minor structural changes can yield up to two additional resonant modes for designing two-port MIMO

Oxygen Transfer from Trimethylamine N-Oxide to CuI Complexes Supported by Pentanitrogen Ligands

[N,N-bis(1-methyl-2-benzimidazolyl)methyl-N-(bis-2-pyridylmethyl)amine] (L1) and [N,N-bis(2-quinolylmethyl)-N-bis(2-pyridyl)methylamine] (L2) were employed to prepare CuII and CuI complexes for spectroscopic and structural characterization. [L1CuII(H2O)](NO3)2 and [L2CuII(NO3)]NO3 have Jahn–Teller distorted octahedral geometries and give rise to isotropic EPR spectra in frozen solution. [L1CuI(CH3

Validity and reliability of the Patient Health Questionnaire-8 in Swedish for individuals with systemic sclerosis

Background: Depressive symptoms are common in rheumatic diseases and influence patients’ quality of life. The Patient Health Questionnaire-9 (PHQ-9), which assesses symptoms of depression, is valid in English in patients with systemic sclerosis (SSc). However, the measurement properties of the PHQ-8 (short version of the PHQ-9) have not been evaluated in Swedish patients with SSc. Objective: To in

Surgical Strategy for Contralateral Groin Management in Patients Scheduled for Unilateral Inguinal Hernia Repair : An International Web-Based Surveymonkey® Questionnaire: Strategy for Contralateral Groin Management during Inguinal Hernia Repair

Background: A contralateral occult inguinal hernia is frequently observed in patients planned for a unilateral laparoscopic inguinal hernia repair. Surgical strategy for contralateral groin management in patients scheduled for an endo-laparoscopic unilateral inguinal hernia repair is controversial and based on questionable evidence. This study aimed to gather international opinion concerning the s

EXPOSED: An occupant exposure model for confined spaces to retrofit crowd models during a pandemic

Crowd models can be used for the simulation of people movement in the built environment. Crowd model outputs have been used for evaluating safety and comfort of pedestrians, inform crowd management and perform forensic investigations. Microscopic crowd models allow the representation of each person and the obtainment of information concerning their location over time and interactions with the phys

Use of proteomics to identify biomarkers associated with chronic kidney disease and long-term outcomes in patients with myocardial infarction

Background: Patients with chronic kidney disease (CKD) have poor outcomes following myocardial infarction (MI). We performed an untargeted examination of 175 biomarkers to identify those with the strongest association with CKD and to examine the association of those biomarkers with long-term outcomes. Methods: A total of 175 different biomarkers from MI patients enrolled in the Swedish Web-System

Synthetic biology approaches to dissecting linear motor protein function : towards the design and synthesis of artificial autonomous protein walkers

Molecular motors and machines are essential for all cellular processes that together enable life. Built from proteins with a wide range of properties, functionalities and performance characteristics, biological motors perform complex tasks and can transduce chemical energy into mechanical work more efficiently than human-made combustion engines. Sophisticated studies of biological protein motors h

Lipoprotein-associated phospholipase A2 activity, genetics and calcific aortic valve stenosis in humans

Background: Lipoprotein-associated phospholipase A2 (Lp-PLA2) activity has been shown to predict calcific aortic valve stenosis (CAVS) outcomes. Our objective was to test the association between plasma Lp-PLA2 activity and genetically elevated Lp-PLA2 mass/activity with CAVS in humans. Methods and results: Lp-PLA2 activity was measured in 890 patients undergoing cardiac surgery, including 476 pati

Development of Iron Speciation Reference Materials for Palaeoredox Analysis

The development and application of geochemical techniques to identify redox conditions in modern and ancient aquatic environments has intensified over recent years. Iron (Fe) speciation has emerged as one of the most widely used procedures to distinguish different redox regimes in both the water column and sediments, and is the main technique used to identify oxic, ferruginous (anoxic, Fe(II) cont

Correlation between dendrite diameter and action potential amplitude in sex pheromone specific receptor neurons in male Ostrinia nubilalis (Lepidoptera: Pyralidae)

Outer dendritic segments of olfactory receptor neurons tuned to sex pheromone components were measured morphometrically on the antenna of male European corn borers. Ostrinia nubilalis, to determine if a correlation exists between the diameter of the outer dendritic segment and the spike amplitude. The olfactory sensilla investigated each contained three receptor cells. Two cells were each specific

Electrophysiological and behavioral responses of turnip moth males, Agrotis segetum to fluorinated pheromone analogs

The electrophysiological and behavioral responses of male Agrotis segetum to fluorinated analogs of (Z)-5-decenyl acetate (Z5-10:OAc) were investigated. The single sensillum recordings showed that 4,4-difluoro-(Z)-5-decenyl acetate (4,4-F2), 7,7-difluoro-(Z)-5-decenyl acetate (7,7-F2), 10,10,10-trifluoro-(Z)-5-decenyl acetate (10,10,10-F3) and 7,7,8,8-tetrafluoro-(Z)-5-decenyl acetate (7,7,8,8-F4)
