We present a non-contact platelet functional analysis platform based on acoustic trapping of platelet clusters and activation monitoring using impedance spectroscopy. The system was characterized using polystyrene particles and human platelets. The system was also capable of transferring platelets from plasma into a controlled buffer. Trapped platelets were activated using 20 and 40 μM TRAP and th

Den här studien handlar om körsång och dess potentiella påverkan på människor. Syftet är att ta reda på om – och hur körsångarna i Sinnesrokören upplever att körsången påverkar dem och vilka faktorer det är som gör att de i sådana fall påverkas. Körledarens drivkrafter och mål och hur dessa visar sig i praktiken undersöks också. Studien har en kvalitativ ansats och metoderna som använts är intervjThis study is about choir singing and its potential influence on people. The purpose is to find out if - and how the singers in the Serenitychoir experience that the choir singing affects them, and what factors matter when it comes to forming the experience. The choir conductor’s intentions and goals and how are transformed into practice are also investigated. The study has a qualitative approach

Konflikten i den Syriska Arabiska Republiken började för mer än tio år sedan och ingen lösning är i sikte. Konflikten anses vara den mest dokumenterade konflikten någonsin. Trots att konflikten har pågått under en lång tid saknas det straffrättsligt ansvar för de begångna brotten. Det har gjorts försök, att genom användandet av international straffrätt hänvisa konflikten till den Internationella BThe conflict in the Syrian Arab Republic is ongoing since more than ten years, and there is no end in sight. The conflict is deemed to be the most documented conflict of all time. Despite the longevity of the conflict, there has been a lack of criminal accountability for the crimes committed. The international community has through the use of international criminal law attempted to refer the confl

Abstract in English The purpose of this study is to compare the story about Emil i Lönneberga by Astrid Lindgren with the translation Miguel el travieso by Marina Escanilla. The story chosen contains a lot of cultural elements, which appear difficult to translate. The intention is to show that, when translating cultural words, the essential culture of Småland, and the antique and rural of the époq

Airborne depth sounding lidar has proven to be a valuable sensor for rapid and accurate sounding of shallow areas. The received lidar pulse echo contains information of the sea floor depth, but also other data can be extracted. We currently perform work on bottom classification and water turbidity estimation based on lidar data. In this paper we present the theoretical background and experimental

Sammanfattning Politik och media är beroende av varandra och vi finner det därför intressant att studera hur internet och sociala medier spelar en allt större roll i den politiska kommunikationen. Vi har valt att närmare granska hur de svenska riksdagspartiernas politiker handskas med dessa nya kommunikationskanaler, något som är särskilt intressant med tanke på att det är valår. Vår ansats är kva

We show acoustic separation of 7.8 µm from 5 µm fluorescent polystyrene particles at an unprecedented sample flowrate of almost 1000 µL/min.

Pulmonary arterial hypertension (PAH) is a lethal condition where expansion of the vascular extracellular matrix contributes to increased pulmonary vascular resistance. Versican, a chondroitin sulfate proteoglycan, is known to accumulate in vascular lesions of PAH and hyaluronan and tenascin-C, binding partners of versican, are elevated in PAH. The specific distribution and localization of versica

Square Kilometer Array (SKA) is a project aimed to build the largest radio telescope in the world and it has just gotten into the construction phase. In this phase, the ability to develop and integrate software in an integration environment is crucial as it is the ability to visualize system-related information via a User Interface to rapidly verify the correctness of the system behavior and spot

Bildandet av blodceller, hematopoesen, utgår från ett litet antal av de så kallade hematopoetiska stamceller som sitter i vår benmärg. Dessa celler har förmågan att ge upphov till alla mogna blodcellstyper av de tre hematopoetiska linjerna, samtidigt som de genom celldelning bibehåller sin egna mängd. Det har uppskattats att vi endast har några tusen hematopoetiska stamceller, men trots deras rela

Digital technology plays an important role in our work places, and much time is spent in the virtual environments that technol-ogy provides. However, today’s digital work environments are often cumbersome and hard to use, and contribute to stress and ill-health with subsequent cost to the individual, to their employ-ers and to society. Our long-term aim is to facilitate the develop-ment of IT syst

We present a new experimental method for the measurement of the compressibility of cells by analysis of free flow acoustophoresis separation data.

We report a new method to select the optimal actuation frequencies in bulk acoustophoresis devices, by means of differential impedance spectrum analysis measured via the actuating piezoelectric transducer (piezo). The impedance spectra is rich of large spurious resonance peaks originating from bulk resonances not related to the channel resonance, Fig. 1a, why direct measurement of the piezo impeda

In the present study, we apply deterministic chaos theory to investigate nonlinear dynamics in monthly precipitation at Mokpo, Korea, after wavelet decomposition. The wavelet transform is used not only for removal of noise but also for extraction of low and high frequency components in the data, representing low-dimensional dynamics. In order to determine an appropriate decomposition level for the

During March 2020 a large-span arena, Tarfalahallen, collapsed. The main load-bearing girders with a 54 m span were high and slender glulam trussed beams, supported from below by a cable system via vertical struts. Investigations concluded that the failure was initiated by out-of-plane buckling of the struts and slender beam, in spite of lateral stabilization by steel roof sheeting at the top edge

Objective: Antimuscarinic treatment in fasted mice and rats causes clonic convulsion soon after food intake. This study was designed to evaluate the electrophysiological markers of these convulsions and fasting in electrocorticograms in rats. Methods: Male Wistar albino rats were stereotaxically implanted with 10 cortical electrodes, and baseline electroencephalogram recordings were taken for 10 m

We have developed a microfluidic chip for isolation of circulating tumor cells (CTCs) in blood based on microchannel acoustophoresis. Ultrasound radiation forces are used to separate cancer cells from blood cells in a continuous flow format. Separation was dramatically improved after incorporation of a 2-dimensional acoustic pre-alignment of the cells before entering the acoustophoresis separation

This work presents an acoustofluidic chip capable of separating cells form their corresponding secretome for subsequent MALDI-MS analysis, which can be used amongst many other applications for directed evolution.
