Acoustic Trapping in Biomedical Research

Popular Abstract in Swedish I naturen finns en närmast oändlig variation av biologiska partiklar i storleksordningen 100 nanometer till 10 mikrometer. Bland dessa kan man bland annat finna; eukaryota celler som genom ordnad samverkan bygger upp flercelliga organismer, prokaryota celler vilka lever som solitära organismer såsom olika bakterier eller jästsvamp, och viruspartiklar vilka likt parasiteHerein a method that uses acoustically resonating glass capillaries and enables non-contact capture of micron-sized bioparticles, i.e. acoustic trapping, is described. A miniaturized ultrasonic transducer is used to locally actuate a cross-sectional resonance in the capillary. A 2000×200 µm2 capillary is typically operated around a resonance frequency of 4-MHz. Optimal design of the transducer for

Electrical isolation of coils in Soft Magnetic Composite applications

Soft Magnetic Composites (SMC) based on iron powder have a strong potential for improving both the performance and the manufacturing of various electromagnetic components and devices, such as inductors, induction heaters and electrical machines. A new casting or moulding method we have developed makes use of a modified composite, termed SM2C, or soft magnetic mouldable composite. Use of it makes i

Model separability indices for efficient dynamic simulation

This paper proposes a means to quantify the aptitude of a dynamic model to be partitioned into weakly coupled submodels. The proposal applies to both linear and nonlinear systems, is largely independent of their scale, and requires information that is easy to provide on the part of the analyst. The presented indices can be exploited in different manners, from easing numerical integration on monoli

On the thermal broadening of core levels in metals due to many‐electron effects

Ferrell's expression for the XPS lineshape is derived in a formalism which explicitly takes the electron—electron interaction into account. Also the corresponding expression for X-ray absorption is given. In the presence of other broadenings, which are comparable or larger than kT, the electronic part of the core-level broadening in XPS is indistinguishable from a Gaussian. This Gaussian broadenin

Assessment of Multipath in Aeronautical Environments

In the last years the usage of Global Navigation Satellite Systems (GNSS) systems for aviation was a quickly growing field. In this context the problem of multipath reception becomes crucial as aviation demands high accuracy navigation based upon GNSS throughout all phases of flight and in particular with strong requirements for the approach and landing phase. To address this issue, simulations ha

The Consequences of a Fragmented Climate Governance Architecture: a Policy Appraisal

This chapter complements the analysis in Chapter 2 by a policy-oriented inquiry of how different degrees of fragmentation of governance architectures are likely to affect the environmental effectiveness of policies. Our study relates here to an area of widespread contestation in academic and policy writing. It is often maintained, as we describe further below, that a more integrated climate govern

The political theology of IKEA: An ethnographical account of subjectification at an IKEA store

Abstract in UndeterminedThis paper is an ethnographical account of a visit to the IKEA store in Älmhult, Sweden. In this paper IKEA is understood as something beyond a retailer offering consumer goods to consumers, and the bond between IKEA and the consumer is understood as something emerging before and extending beyond the contract into which the consumer enters as she or he pays for the goods be
