We present a novel method for the determination of density and compressibility of individual particles and cells undergoing microchannel acoustophoresis in an arbitrary 2D acoustic field. Our method is a critical advancement within acoustophoretic separation of biological cells, as the ability to determine the density and compressibility of individual cells enables the prediction and alteration of

We present, for the first time, separation of three different prostate cancer cell lines from leukocyte fractions by means of continuous flow acoustophoresis. This flow-through separation approach, which utilize acoustophoretic forces to extract CTCs from blood has a significant advantage over affinity based methods in the sense that it comprises a non-contact and label free separation of CTCs fro

Antibody microarrays are becoming increasingly established in clinical studies. However, the arrays are seldom used in a quantitative approach but rather for detecting up or down regulated proteins. In this study we describe a microarray procedure being standardized by placing the in-house developed porous silicon surfaces into a commercially available 96 well microtiter plate for analyzing the PS

An Integrated Selective Enrichment Target (ISET), microfabricated for efficient on-bead enzymatic digestion of proteins compatible for a direct interface with matrix-assisted laser desorption /ionization mass spectrometry (MALDI MS) is presented.

Full 3" wafer scale fabrication of porous silicon chips (pore chip protein arrays -PCPA) is reported. The PCPA is developed for the analysis of protein molecules based on the fluorescence and MALDI-TOF MS detection. The surface porosification process allows the creation of chips with different surface geometries to control the physical properties of the matrix in a highly reproducible way.

Conventional fixation of large solid surgical specimens is a slow process. Consequently, autolytic damage to tissues may occur if the fixative does not reach the central part of the specimen in time. However, as there is also a time relationship between formalin fixation and antigen masking, fixation for too long can also be detrimental. In seeking the optimum balance for fixation, microwave irrad

To date, most studies on coupled-water-and-heat processes in frozen soils haves focused on the mechanism of changes in frozen soil and the contribution of climate change, hydrological processes, and ecosystems in cold regions. Several studies have demonstrated considerable improvements in the accuracy of simulating water and heat transfer processes in cold regions. However, substantial differences

Institutionen för kultur och samhälle vid Linköpings universitet får härmed avge yttrande som utarbetats av professorerna Anna Lundberg och Anders Neergaard.En övergripande utgångspunkt för utredningen har varit att migrationspolitiken ska vara långsiktigt hållbar, human, rättssäker och effektiv. I det följande lämnar vi synpunkter utifrån denna utgångspunkt. Vi menar sammantaget att kommittén int

Introduction: A detailed understanding of respiratory support patterns in preterm infants is lacking. The aim was to explore and visualize this practice in Sweden. Methods: Preterm infants with gestational ages of 22-31 weeks, admitted to neonatal units reporting daily to the Swedish Neonatal Quality Register and discharged alive in November 2015-April 2022, were included in this descriptive cohor

In the coming renewables-based energy transition, global electricity consumption is expected to double by 2050, entailing widespread end-use electrification, with significant impacts on energy efficiency. We develop a long-run, worldwide societal exergy analysis focused on electricity. Our 1900–2017 electricity world database contains the energy carriers used in electricity production, final end-u

Aims: Preclinical and human studies suggest that a social partner's genotype may be associated with addiction-related outcomes. This study measured whether spousal genetic makeup is associated with risk of developing drug use disorder (DUD) during marriage and whether the risk associated with a spouse's genotype could be disentangled from potentially confounding rearing environmental effects. Desi

The influence of aeration diffuser system design on electricity usage, effluent water quality, and life-cycle cost in biological wastewater treatment was investigated. A plant-wide model was implemented, and simulations were carried out with different process configurations and aeration systems. Model-aided design of new aeration diffuser systems could significantly decrease electricity usage and

Remodelling is an important process in bones in order to maintain bone mass and to recover cracks which naturally develop within the bone material. There is agreement in the literature that the piezoelectric characteristic of bones is one possible initiator of bone remodelling. In recent experimental studies, however, it has been found that cortical bone also exhibits flexoelectric properties whic

This paper introduces the use of a multi-zone modelling approach for analysing smoke spread in tunnels. The approach suggested in this paper is based on an existing model, i.e., the Multi-Zone Fire model developed for large spaces. The Multi-Zone Fire model has been adapted and modified for tunnel fire scenarios by including features that consider longitudinal ventilation flow, tunnel gradient and

Soil erosion has created landscape problems in many parts of the world and in particular in cold regions where the sensitive permafrost conditions have changed due to climate warming. Such a case occurred in the Tibetan Plateau (TP), which has been strongly affected by global warming and human activities. Monitoring technologies, like remote sensing and field surveys were used to explore soil eros

Background: Social anxiety disorder (SAD) is associated with aberrant emotional information processing while little is known about non-emotional cognitive processing biases. The dorsal anterior cingulate cortex (dACC) has been implicated in SAD neuropathology and is activated both by emotional and non-affective cognitive challenges like the Multisource Interference Task (MSIT). Methods: Here, we u
