We present experimental results and simulations on a simple method for tunable particle separation based on a combination of Deterministic Lateral Displacement (DLD) and Insulator Based Dielectrophoresis (I-DEP). Rather than deriving its tunability from its elastic properties[1], our present device uses an applied AC field to perturb the particle trajectories in the pressure-driven flow and is the

The local alignment of DNA stretched in nanofluidic channels is measured using polarization sensitive detection. With increased degree of stretching the polarization anisotropy increases both in the deGennes and the Odijk regime. The technique is expected to find use in studies of, for example, local conformational changes in polymer physics in confined spaces, studies of protein-DNA interactions

Within a course in academic writing, first-term students of English currently construct individualized study-plans detailing both what they should do during the term and when they should do it. Students calculate the average workload for all their courses, and include in their study-plans all the hours they should spend both in and outside the classroom on each course, totalling in 40-hour working

Objective: To describe the prevalence, baseline characteristics and factors associated with survival in out-of-hospital cardiac arrest (OHCA) with initial non-shockable rhythm sub-grouped into pulseless electrical activity (PEA) and asystole as presenting rhythm. Methods: The Swedish Registry of Cardiopulmonary Resuscitation is a prospectively recorded nationwide registry of modified Utstein param

Background: The power and influence of the hidden curriculum - culturally situated norms and values - onlearning opportunities is a growing concern in medical education. However, while medical schools producediversity and equal treatment policies, efforts towards surfacing and addressing equal opportunities in theclinical learning environment trail behind.Summary of Work: To better understand how

Denna artikel beskriver den bokutgivning som skedde inom ramen för tidskriften Zenit mellan åren 1968 och 1982. Zenit gav ut böcker i egen regi men redigerade också tre bokserier på Bo Cavefors förlag(två st.) och på Raben & Sjögren (1). Böckerna gavs typografisk form av Leif Thollander. Tidskriftens Zenits bakgrund i den ""nya vänstern"" skisseras. Bokutgivningens innehåll och karaktär beskri

Purpose: The study aims to focus on rotation effects on a ribbed channel of gas turbine blades for internal cooling. The combination and interaction between secondary flows generated by angled rib geometry and Coriolis forces in the rotating channel are studied numerically. Design/methodology/approach: A radially outward flow passage as an internal cooling test model with and without ribs is used

Purpose: The purpose of this study is to enhance the thermal performance in the labyrinth channel by different ribs shape. The labyrinth channel is a relatively new cooling structure to decrease the temperature near the trailing region of gas turbine. Design/methodology/approach: Based on the geometric similarity, a simplified geometric model is used. The k − ω turbulence model is used to close th

The food industry is actively adopting carbon neutral strategies aligned with the principles of Industry 4.0 to establish long-term goals for reducing carbon emissions and accelerating the transition to a low-carbon food production industry. Industry 4.0, often referred to as the fourth industrial revolution, emphasizes the integration of digital technologies, automation, and data exchange into ma
