Comparative Seismic Laboratory and Non-Contact Field Measurements of Asphalt Concrete

Non-contact acoustic field measurements are performed on a newly built highway to characterize the real part of the dynamic modulus of the asphalt concrete (AC) top layer. The in situ measurements are performed using an array of 48 micro-electromechanical system (MEMS) sensors. Cores extracted from the field measurement positions are then examined in a laboratory using seismic modal testing for co

Inflammation and Stem Cell Therapy for Stroke

Ischemic stroke is a leading cause of death and disability worldwide. Currently, there is no treatment that can promote recovery in the chronic phase. It has been shown that neurogenesis occurs in ischemic striatum in rodents and probably also in humans. Moreover, blood-borne macrophages have been found to enhance spontaneous post- stroke recovery in mice. These findings have suggested potential n

Jitter-correction for IR/UV-XUV pump-probe experiments at the FLASH free-electron laser

In pump-probe experiments employing a free-electron laser (FEL) in combination with a synchronized optical femtosecond laser, the arrival-time jitter between the FEL pulse and the optical laser pulse often severely limits the temporal resolution that can be achieved. Here, we present a pump-probe experiment on the UV-induced dissociation of 2,6-difluoroiodobenzene (C6H3F2I) molecules performed at

The Entangled Media Geographies of the Nordics : Contemporary Scandinavian Production Practices through the Prism of Audio-visual Nordic Noir

The Entangled Media Geographies of the Nordics: Contemporary Scandinavian Production Practices through the Prism of Audio-visual Nordic Noir.Olof Hedling, Lund UniversityAlthough predominantly contemporary in its outlook, this paper attempts to grabble with a particular development in media history, namely the gradual de-nationalization, or, perhaps more accurately, the increasingly transnational

Extracting Cardiac Information From the Pressure Sensors of a Dialysis Machine

This doctoral thesis in biomedical engineering deals with cardiac monitoring using the built-in extracorporeal blood pressure sensors of a hemodialysis machine. Patients treated with hemodialysis often suffer from cardiovascular disease. Despite this, cardiac monitoring is not routinely performed during dialysis treatment, since external devises required for such monitoring causes patient discomfo

NUMERICAL INVESTIGATION OF AN OSCILLATING GAS BUBBLE IN AN ULTRASONIC FIELD

The discovery of acoustic cavitation phenomenon is an important role in the design of a wide range of devices handling liquids and it has led to a renewed interest in the bubble dynamics in a sound field.In this study, the nonlinear behaviour of individual gas bubble in liquid under the action of ultrasound fields has been analysed, and simulated results of formation and collapse of a bubble have
