INTRODUCTION: The FEV1 quotient (FEV1Q), calculated as the index between FEV1 and a theoretical lower survivable FEV1 threshold of 0.4L for females and 0.5L for males, has been investigated as a novel method of interpreting results from lung function testing. The applicability of the FEV1Q in populations with chronic respiratory failure has not been studied, and the continuous association between

We investigated the impact of inertial forces on acoustic sorting at high sample throughputs. Above a critical flow rate, we observed an unexpected inertia induced breakdown of the sorting efficiency that is not due to the wall induced lift force and was not previously described in the literature. We analyzed the effect experimentally and theoretically, providing an explanation to the phenomena, a

Acquisition of entomological data with high-frequency lidar is an emerging research field in rapid development. The technique offers very high numbers of observations per time unit, suitable for statistical models. In this work, we use a near-infrared Scheimpflug lidar with a sampling frequency of 3.5 kHz to assess the activity of free flying organisms. In-situ measurements were done during the ra

This work presents a novel concept for acoustofluidic cell manipulation: thin vibrating channel walls. Improved etch recipes enable us to produce thin walls between two microfluidic channels, fabricated in silicon or via PDMS casting, that can be used for challenging microbiological applications. We demonstrate the medium exchange for bacteria utilised for transformation, single-cell rotation for

Structural Health Monitoring (SHM) can provide valuable information for maintenance-related activities and post-disaster emergency management. However, as with any technological system, SHM systems can be susceptible to errors due to malfunctioning. Therefore, it is essential to assess the potential for malfunctions and the associated costs of maintenance and repair when evaluating the long-term b

Differences in morphologies of bacteria and bacteria clusters are thought to contribute to their virulence and colonization. However, the conventional standard cell biological methods cannot separate bacteria and bacteria clusters based on their morphologies and sizes, making studies of the underlying mechanisms difficult. Here we report a simple label-free method for the continuous separation of

Kameraövervakning utgör en pågående trend i kommuners och privatpersoners kamp mot brottslighet. Föremålet för denna rapport är ett särskilt fall som sedan april 2004 ansluter till denna trend: övervakningen av parkeringsplatsen på Kasernplan i centrala Landskrona. Rapporten utgår från statistik, medierapportering, enkätundersökningar samt etnografiskt material (intervjuer och fältanteckningar)

The paper reviews a number of cellular neural network implementations on a field-programmable gate-array. It illustrates experimentally, how these implementations can be used to measure from images or to create dynamic, autonomous processes that facilitate measurements within topographic maps. Applications range from image understanding to robot navigation

Abstract in UndeterminedSometimes energy security is used as an advocacy for renewable energy systems. Although renewable energy systems can surely have such characteristics they will not per se solve all types of security problems, and new problems will most certainly arise. In this paper, energy security aspects of renewable energy systems are analysed taking the starting point in a broad typolo

Based on articles published 1990-2004 in 21 LIS journals, a set of co-citation analyses were performed to study changes in research fronts over the last 15 years, where LIS is at now; and to discuss where it is heading. To study research fronts, here defined as current and influential co-cited papers, a citations among documents methodology was applied; and to study changes, the analyses were time

The acoustic emission that is detectable in the forming of complex thin part plates contains information about the quality of the pressed plates. The information can be used as process control and to filter out advanced thin plates with defects such as cracks. The article describes the results obtained in a try-out pressing process in special developed punch-die pairs with different pressing
