Extending imaging range in magnetomotive ultrasound with tailored magnetic nanoparticles

In magnetomotive ultrasound (MMUS), magnetic nanoparticles (MNPs) are used as a contrast agent. A time-varying magnetic field displaces the MNPs which in turn move their closest surrounding - a motion detected with ultrasound. A limiting factor for MMUS is the magnetic force magnitude decay with depth, which restricts the imaging area. Several attempts to extend the imaging depth have been suggest

The magnetic force generation in magnetomotive ultrasound imaging

In magnetomotive ultrasound imaging, the tissue displacement due to a magnetic force on embedded magnetic nanoparticles is measured. It was previously shown that the nanoparticle contrast agent exhibits a non-linear magnetization characteristic, which is also reflected in the magnetomotive force. However, this non-linearity was rarely taken into account for the application. Here, the implications

Synthesis and Characterization of a Biocomposite Bone Bandage for Controlled Delivery of Bone-Active Drugs in Fracture Nonunions

Fracture nonunions are common in orthopedics and their treatment often involves multiple surgical interventions. The aim of this study was to fabricate and characterize a gelatin-nano-hydroxyapatite membrane (GM)-based bone bandage for controlled delivery of bio-active molecules; recombinant human bone morphogenic protein-2 (rhBMP-2) and zoledronic acid (ZA) to promote osteoinduction and prevent c

Evaluation and optimization of ICOS atmosphere station data as part of the labeling process

The Integrated Carbon Observation System (ICOS) is a pan-European research infrastructure which provides harmonized and high-precision scientific data on the carbon cycle and the greenhouse gas budget. All stations have to undergo a rigorous assessment before being labeled, i.e., receiving approval to join the network. In this paper, we present the labeling process for the ICOS atmosphere network

Associations of carbohydrates and carbohydrate-rich foods with incidence of type 2 diabetes

Dietary carbohydrates have long been expected to be associated with risk of type 2 diabetes; however, the associations for many carbohydrates and carbohydrate-rich foods remain inconclusive. This study analysed associations between intakes of six types of carbohydrates and thirteen carbohydrate-rich foods with incident type 2 diabetes in 26 622 participants (61% women) in the Malmö Diet and Cancer

Changing the System Culture : Mobilizing the Social Sciences in the Swedish Nuclear Waste System

The purpose of this paper is to analyze how competence in the humanities and social sciences has been introduced into the system culture of the Swedish nuclear waste system (SNWS) traditionally dominated by scientists and engineers. In the spring of 1980, fierce local protests were directed against drilling teams sent out to investigate the geology of potential locations for a repository of spent

Long-term outcome of the Surgisis® (Biodesign®) anal fistula plug for complex cryptoglandular and Crohn’s fistulas

Aim: To evaluate the long-term success rate of treatment with the Surgisis® (Biodesign®) anal fistula plug for complex anal fistulas, assess fistula plug failure over time and compare success rates for fistula plug between a group of patients with cryptoglandular fistula and another group with Crohn's fistula. Method: This is a single-centre study of consecutive patients treated with the Surgisis®

Predictability of food supply modulates nocturnal hypothermia in a small passerine : Food supply and nocturnal hypothermia

The combination of short days and long cold winter nights, in temperate regions, presents a major challenge for small diurnal birds. Small birds regularly employ heterothermy and enter rest-phase hypothermia during winter nights to conserve energy. However, we know little about how environmental conditions, such as food availability, shape these strategies. We experimentally manipulated food avail

Combining expansion in pulp capacity with production of sustainable biofuels – Techno-economic and greenhouse gas emissions assessment of drop-in fuels from black liquor part-streams

Drop-in biofuels from forest by-products such as black liquor can help deliver deep reductions in transport greenhouse gas emissions by replacing fossil fuels in our vehicle fleet. Black liquor is produced at pulp mills that can increase their pulping capacity by upgrading some of it to drop-in biofuels but this is not well-studied. We evaluate the techno-economic and greenhouse gas performance of

Transcultural Music-Making in Contemporary Music Ensembles : Five Approaches in Germany, the Netherlands, Uzbekistan and Turkey

The present article describes the approaches of five ensembles specialized in transcultural music-making in the context of contemporary music in Germany, the Netherlands, Uzbekistan and Turkey. While facing similar underlying conceptual and practical challenges in the process of combining different musical traditions and cultural backgrounds, such as the question of how to merge oral and notated t

Explaining value: on Orsi and Garcia’s explanatory objection to the fitting-attitude analysis

Orsi and Garcia (Philos Stud, 2020, https://doi.org/10.1007/s11098-020-01471-6) argue that fitting-attitude analysis of value (FA-analysis, for short) isvulnerable to an explanatory objection. On FA-analysis, for an object to be valuable is for it to be a fitting target of an attitude—a pro-attitude if its value is positive and a con-attitude if it is negative. For different kinds of value differeOrsi and Garcia (Philos Stud, 2020, https://doi.org/10.1007/s11098-020-01471-6) argue that fitting-attitude analysis of value (FA-analysis, for short) isvulnerable to an explanatory objection.

Data Narrator : Digital Chronotopes in Contemporary Chinese Science Fiction

In this brief comparison of three examples from contemporary Chinese SF, we see the impossible topology of the digital realm envisioned as a lightscape, a seascape, and as a cityscape under surveillance. The digital chronotopes explored include the computer-generated alternative reality in Liu Cixin's The Three-Body Problem, the ocean of data in Tang Fei's “Call Girl,” and language as World Wide W

Implementing guidelines for interventions in Swedish substance abuse treatment : A national evaluation of outcomes from 2010 to 2014

In 2009, the Swedish government launched a nationwide dissemination and implementation project regarding substance abuse treatment, Knowledge to Practice (KTP), which was commissioned by the Swedish National Board of Health and Welfare (SoS). Aim: The study aimed to evaluate the effectiveness of a national project to disseminate and implement evidence-based assessment instruments and treatment met

Nanotomographic evaluation of precipitate structure evolution in a Mg-Zn-Zr alloy during plastic deformation

Magnesium and its alloys attract increasingly wide attention in various fields, ranging from transport to medical solutions, due to their outstanding structural and degradation properties. These properties can be tailored through alloying and thermo-mechanical processing, which is often complex and multi-step, thus requiring in-depth analysis. In this work, we demonstrate the capability of synchro

Repetitive non-thermal melting as a timing monitor for femtosecond pump/probe X-ray experiments

Time-resolved optical pump/X-ray probe experiments are often used to study structural dynamics. To ensure high temporal resolution, it is necessary to monitor the timing between the X-ray pulses and the laser pulses. The transition from a crystalline solid material to a disordered state in a non-thermal melting process can be used as a reliable timing monitor. We have performed a study of the non-
