The handling of biochemically functionalised beads or particles is becoming increasingly important in µTAS. Bead-based analysis of e.g. proteins can be made sensitive due to the large active surface area and flexible by chemical design of the bead surface. We have developed a microfluidic device utilising an array of integrated and individually controlled ultrasonic microtransducers for particle t

We present the results of 3D high-resolution calculations of the last inspiral stages and the final coalescence of neutron star binary systems. The equations of hydrodynamics are solved using the smoothed particle hydrodynamics method with up to 106 particles. Using Newtonian gravity, but adding the forces emerging from the emission of gravitational waves, we focus on the impact of microphysics on

Popular Abstract in Swedish Stora framsteg har gjort det möjligt att, med dagens teknik, inte bara visualisera enskilda atomer, utan även utföra olika typer av operationer och manipulationer på atomskalan med stor precision rent experimentellt. Detta har möjliggjort tillverkning av komplexa nanostrukturer genom montering av komponenter av nanostorlek till större sammansatta system, vilket i sin tuNanowires constitute one of the fundamental building blocks in assembled nanodevices. Due to the high surface to volume ratio, the fraction of surface atoms is not negligible for nanosized elements. Because of the reduced coordination of surface atoms, the physical properties deviate from those of the bulk, which influences the overall physical properties of nanostructures. Consequently, this prov

The aim was to elucidate the cardiovascular response associated with breath-hold diving, especially the effects of temperature in its elicitation and the effects of different types of training on the human diving response (DR) and breath-holding time (BHT), and to evaluate the human DR in a mammalian perspective. A model for simulated diving by apnea and facial immersion in cold water was develope

Heat transfer in gas turbine related applications is investigated by steady state liquid crystal thermography (LCT) in this thesis. The work presented includes outlet guide vane heat transfer and gas turbine internal cooling.The heat transfer on the outlet guide vane (OGV) surface and its endwall region is investigated experimentally in a linear cascade test facility. The inlet flow angle is varie

The delineation and characterization of fracturing is important in the successful exploitation of many hydrocarbon reservoirs. Such fracturing often occurs in preferentially aligned sets; if the fractures are of subseismic scale, this may result in seismic anisotropy. Thus, measurements of anisotropy from seismic data may be used to delineate fracture patterns and investigate their properties. Her

Understanding the molecular details of bioenergetic processes is fundamentally important. Defects in the mitochondrial energy metabolism can lead to untimely apoptosis and thus cause serious degenerative human diseases. Other defects in mitochondrial energy metabolism can have the reverse effect and cause cell immortality and also contribute to and high metastatic potential of tumor cells. Knowi

To be able to predict the strength of climate change and its consequences for mankind, it is of major importance to understand the contemporary greenhouse gas exchange of the terrestrial biosphere, as well as its response to changes in climate. To achieve such understanding both descriptive studies and manipulation experiments are required. Northern peatlands represent an important ecosystem type

The short-term limit value for PM10 having become effective in January 2005 was exceeded in many regions within the EU in 2005 and 2006. Therefore, strategies, particularly with respect to traffic control, are discussed, which could cause reduced PM10 concentrations leading to a more effective compliance with the short-term PM10 limit value. These strategies are often justified on PM10 differences

Popular Abstract in Swedish Pankreascancer (cancer i bukspottkörteln) utgör fjärde orsak död i cancer. Det är den cancerform som har den dystraste prognosen av alla, med en 5-års överlevnad mindre än 6%. Sjukdomsrelaterade symptom uppträder ofta sent i förloppet och det saknas metoder för tidig diagnos varför de flesta av patienterna upptäckts i sent skede. Endast cirka 20 procent av patienterna kPancreatic cancer (PC) is the fourth leading cause of cancer-related deaths, with a 5-year survival less than 6%. It does not show any symptoms in its early stages, hence most (>85%) of the patients are diagnosed at late stage. At the time of diagnosis, metastases are frequently observed which make most patients unsuitable for curative surgical treatment and chemotherapy remains the only choice fo
