This abstract reports a novel acoustofluidic method to measure the hematocrit level of a whole blood sample within 20 seconds. The method is substantially faster than conventional centrifugation methods, has no moving parts and can be fully automated and integrated with further unit operations for analysis of blood samples at the point of care [1].
Students’ learning developments of limits were studied in a calculus course. Theiractions, such as problem solving and reasoning, were considered traces of theirmental representations of concepts and were used to describe the developmentsduring a semester. Several students went through the course with a vague conception of limits which in some cases was wrong. A higher awareness about their mental
The paper presents a work in progress which is part of a larger study. Studentslearning analysis was investigated with the aim to find out how their concept images changed from the beginning of an analysis course to a year after the course. Their links between concepts were studied after the year had passed. The influence of the students’ pre-knowledge was durable and sometimes prevented students
We present a microchannel-based adaption of density-gradient centrifugation that allows the instantaneous, precise, and repeatable generation of a 1-dimensional mass-density gradient and determination of single-cell densities with integrated mass-density calibration.
We present a fabrication scheme of contacting arrays of vertically standing nanowires (NW) for LEDs (Duan et al. Nature 409:66–69, 2001), photodetectors (Wang et al. Science (NY) 293:1455–1457, 2001) or solar cell applications (Wallentin et al. Science (NY) 339:1057–1060, 2013). Samples were prepared by depositing Au films using nano-imprint lithography (Ma rtensson et al. Nano Lett 4:699–702, 200
Inom besöksnäringen är delningsekonomins utbredning särskilt tydlig och inom denna industri återfinns en rad företag såsom Airbnb, Vayable, Getmyboat, OffWeFly, EatWith, Uber, Fodora och Travelbuddy. Airbnb, som förmedlar uthyrning av privatpersoners bostäder som en sorts hotellrum, är kanske det mest välkända företaget. Typiskt för delningsekonomin i tjänstesektorn är digitala plattformar som sam
This paper describes and discusses the development of mobile exergames for children with cerebral palsy. The design process was built on co-design, and resulted in three activity games, two augmented reality (AR) games and one GPS based game. The resulting activity games were evaluated by 8 per-sons with cerebral palsy (CP). To complement this evaluation, the games have been evaluated against exis
The PET-CT imaging modality is based on positron emission tomography combined with computed tomography. Before a PET-CT examination, a radioactive tracer (also called a radiopharmaceutical) is intravenously injected into the patient. PET technology images the distribution of this tracer element by detecting the decay. In recent years, PET technology has been developed and improved in hardware and
Tiden är knapp att nå uppsatta klimatmål. För att nå dit krävs kraftfulla åtgärder och styrning. Det står även klart att vi inte når ett hållbart transportsystem med bara någrafå åtgärder – det krävs att en mängd olika åtgärder och styrmedel kombineras och införs. Utöver ökad energieffektivisering, byte av drivmedel och ökade transportkostnader krävs även åtgärder och styrmedel för ett mer transpo
Several research studies have shown the importance of physical exercise. The global gym and fitness industry faced a transition from traditional gyms to virtual fitness training during the pandemic lockdowns. A proliferation of applications is available to provide different digital gym experiences. Advagym is one example that uses sensors to track and give feedback to gym goers. Sony's R&D Cen
Various studies have highlighted older persons' problems in potentially failing to keep pace with developments in information technology and the latest technologies that prevent physical and social loss. In contrast to such studies that treat users as static and technology as changing, it's important to understand the use of technology can change over time. For example, older persons have used tec
Vetenskapligt skrivande är ett viktigt moment i studentens grundutbildning. Skrivandet kräver att studenten ska ange källor på ett korrekt sätt i enlighet med en viss stil. Av erfarenhet konstateras att processen att hantera olika stilar kräver tid. Kritiskt tänkande är en grundläggande förutsättning inom vetenskapligt arbete och kräver i sig inte detaljkunskap kring olika stilars struktur. Dagens
