Sample preparation techniques on dynamic shear rheometer testing : round robin tests on bitumen

Three interlaboratory tests conducted by European laboratories were studied, in which 37 laboratories participated in 2018, rising to 46 in 2019 and 2020. A RTFO-aged neat bitumen 20/30 and PMB 45/80-55 in RTFO-aged and unaged conditions were tested using a DSR at frequency of 1.59 Hz with PP08 and PP25 geometries at temperatures ranging from 10°C to 65°C. To assess variation in numerous areas of

Attributing the impacts of ecological engineering and climate change on carbon uptake in Northeastern China

Context: In the past decades, several ecological engineering (eco-engineering) programs have been conducted in China, leading to a significant increase in regional carbon sink. However, the contribution of different eco-engineering programs to carbon uptake is still not clear, as the location of different programs is difficult to identify, and their impacts are concurrent with climate change. Obje

Optimising Changeover through Lean-Manufacturing Principles: A Case Study in a Food Factory

Operations management is a key aspect in any manufacturing business. Optimising the management of manufacturing operations allows improvement of the productivity and efficiency of industrial activities. To achieve this, reducing waste from manufacturing processes and, therefore, implementing lean-manufacturing principles, is key. This article presents a case study to reduce waste in changeover pro

halffloor - 60 second sonic artworks project : #42 - FFPP

The original sound source was part of my field recording regarding my project about lighthouses. I had a chance to meet and interview a lighthouse keeper in Spain; we talked about different soundscapes in the ports nowadays, even though some lighthouses keep functioning visually. An operating foghorn is not mandatory anymore in the EU, therefore most lighthouses don't use it anymore. The lighthous

Flow structure and dynamics behind cylinder arrays at Reynolds number ∼100

The flow behind nine different arrays of cylinders is experimentally investigated via Particle Image Velocimetry (PIV) at a Reynolds number of Re ∼ 100 based on the diameter of the cylinders. Each array consists of a column of four cylinders in front and three in the rear. The horizontal distance between the two columns and the vertical distance between the cylinders within each column are varied

Gaia Data Release 3 : Hot-star radial velocities

Context. The second Gaia data release, DR2, contained radial velocities of stars with effective temperatures up to Teff = 6900 K. The third data release, Gaia DR3, extends this up to Teff = 14 500 K. Aims.We derive the radial velocities for hot stars (i.e., in the Teff = 6900-14 500K range) from data obtained with the Radial Velocity Spectrometer (RVS) on board Gaia. Methods. The radial velocities

Uncovering Environmental Justice in the Small-scale Aquaculture Sector: Evidence from the Province of Bulacan, Philippines

Coastal areas are undergoing significant socio-ecological changes which intensify the control, extraction, and contestation over coastal resources. These changes have severe justice implications for those strongly dependent on coastal resources, including small-scale aquaculture (SSA) farmers. Yet, research on injustices faced by SSA farmers remains limited. By using a case study approach focused

Prolonged stimulation with low-intensity ultrasound induces delayed increases in spontaneous hippocampal culture spiking activity

Ultrasound is a promising neural stimulation modality, but an incomplete understanding of its range and mechanism of effect limits its therapeutic application. We investigated the modulation of spontaneous hippocampal spike activity by ultrasound at a lower acoustic intensity and longer time scale than has been previously attempted, hypothesizing that spiking would change conditionally upon the av

Phantom limb pain--a phenomenon of proprioceptive memory?

Despite the amount of research that has been conducted on phantom limb pain (PLP), the etiology of the condition remains unknown, and treatment options are limited. After an individual loses a limb, the brain continues to detect the presence of the missing limb even though it is no longer attached to the body, likely through proprioceptive signals. The majority of patients with amputations either

Information-to-work conversion in single-molecule experiments : From discrete to continuous feedback

We theoretically investigate the extractable work in single molecule unfolding-folding experiments with applied feedback. Using a simple two-state model, we obtain a description of the full work distribution from discrete to continuous feedback. The effect of the feedback is captured by a detailed fluctuation theorem, accounting for the information aquired. We find analytical expressions for the a

Safe transport of children with disabilities and medical conditions : caregiver experiences

Background: Road vehicle transportation is essential to support community access and participation for all children. However, little is known about the transport patterns of children with disabilities and medical conditions and their caregivers’ experiences supporting them to be transported safely in road vehicles in Australia. Aim: To understand the transport needs of children with disabilities a

Design and evaluation of architectures for efficient generation of control sequences

Ultra millimeter-wave (mmWave) radars have become a vital sensor in automotive, surveillance, and consumer electronics thanks to its precise measurements and low power consumption. However, they required a precise control to coordinate their different modules and produce meaningful data. In this thesis work, we introduce an approach to perform the control and coordination of the radar based in mic

Occupational contact dermatitis in painters : an analysis of patch test data from the Danish Contact Dermatitis Group

BACKGROUND: Painters are among the occupational groups that most commonly experience occupational contact dermatitis, but few investigations exist concerning this occupation.OBJECTIVES: To characterize painters with contact dermatitis and identify the most common allergens associated with the occupation. Materials and methods. All patch test results of 219 painters and 1095 matched controls regist

A rare baroque pipe from the Fremling Collection in Lund

A metal pipe forming part of an ethnographic collection which had arrived in Lund University by around 1820 is said to have been recovered from ‘wildmen’ in North America. This short paper provides a description and images of the object and discusses a set of issues that it implies. Where was it made, by whom, when and by what method? Can credible comparisons be found? Could it possibly have been

Ultrafast Jahn-Teller Photoswitching in Cobalt Single-Ion Magnets

Single-ion magnets (SIMs) constitute the ultimate size limit in the quest for miniaturizing magnetic materials. Several bottlenecks currently hindering breakthroughs in quantum information and communication technologies could be alleviated by new generations of SIMs displaying multifunctionality. Here, ultrafast optical absorption spectroscopy and X-ray emission spectroscopy are employed to track

Regenerating Land, Regenerating Self: Towards a Care-full Regeneration Cycle of Inner-Outer Transformation

The world needs rapid transformation if we are to shift towards more just and regenerative socio-ecological futures. In merging scholarly fields of transformation studies, regeneration and ethics of care this thesis explores the connection between inner-outer regeneration through the in-depth study of a transformative caring process. With a focus on lived experience and affects, this study conduct

Sleep preferentially enhances memory for emotional components of scenes

Central aspects of emotional experiences are often well remembered at the expense of background details. Previous studies of such memory trade-offs have focused on memory after brief delays, but little is known about how these components of emotional memories change over time. We investigated the evolution of memory for negative scenes across 30 min, 12 daytime hours spent awake, and 12 nighttime

Quantifying the Metabolic Signature of Multiple Sclerosis by in vivo Proton Magnetic Resonance Spectroscopy : Current Challenges and Future Outlook in the Translation From Proton Signal to Diagnostic Biomarker

Proton magnetic resonance spectroscopy (1H-MRS) offers a growing variety of methods for querying potential diagnostic biomarkers of multiple sclerosis in living central nervous system tissue. For the past three decades, 1H-MRS has enabled the acquisition of a rich dataset suggestive of numerous metabolic alterations in lesions, normal-appearing white matter, gray matter, and spinal cord of individ
