Purpose: This study aims to clarify the mechanism of film hole location at the span-wise direction of an internal cooling channel with crescent ribs on the adiabatic film cooling performance, three configurations are designed to observe the effects of the distance between the center of the ellipse and the side wall(Case 1, l = w/2, Case 2, l = w/3 and for Case 3, l = w/4). Design/methodology/appro

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

We demonstrate fluidics realized in thin film plastic foils patterned using roll-toroll nanoimprinting lithography (rrNIL). Realizing fluidics devices in thin plastic foils opens up for parallel operation in stacked devices. It also provides a convenient format for storage and distribution of the devices.

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

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

In this article I call for an awareness of the mobile commons– the informal support that exists among migrating people, NGOs, and activists – in relation to the realization of family reunification. Taking its point of departure in a concrete case of family reunification for young unaccompanied children, the article seeks to expose how the traditional legal notion of the liberal subject fails to pr

Introduction: Preeclampsia (PE) is a pregnancy-related disorder associated with maternal hypertension and placental dysfunction. A significant micronutrient during pregnancy is iron, which is important in cellular functions. While iron absorption increases in pregnancy, little is known about the exact mechanisms regulating maternal iron levels and transfer through the placenta in normal and compli

Vi lever i en tid när gränsöverskridande rättsförhållanden blir en allt mer naturlig del av vår vardag. Med det ökade antalet internationella rättsförhållanden ökar också antalet potentiella tvister som har anknytning till mer än ett land. Makar med olika medborgarskap kanske kommer att vilja skiljas och den köpta produkten från det andra landet kanske var felaktig. När tvister av den här typen sk

The rise of online brand communities has transformed consumer/brand interactions, thus affecting consumer engagement and its nomological network. However, scholarly understanding regarding the effect of consumer values on their online engagement remains tenuous. Addressing this gap, we conceptualize a model that attempts to understand the relative effect of consumers’ values (terminal and instrume

Background: Diagnosing internal herniation (IH) in Roux-en-Y gastric bypass (RYGB) patients with acute abdominal pain poses a diagnostic challenge. Diagnostic laparoscopy is often required for a definitive diagnosis. We hypothesized that intestinal ischemia biomarkers would aid in the diagnosing of IH. Objectives: To explore intestinal ischemia biomarkers in diagnosing IH. Setting: University Hosp

Nu för tiden använder människor världen över, medvetet eller omedvetet, molntjänster, där stora mängder personlig information placeras och lagras. Personuppgifter är en av de mest värdefulla tillgångar ett företag kan inneha, och således utnyttjar företag runt om i världen sådan personlig information för kommersiella syften. Samtidigt har statliga myndigheters övervakning av personer och insamlingToday, people all around the world, consciously or unconsciously, use services provided by cloud computing where large amounts of personal data is placed and stored. Personal data is one of the most valuable assets a company can hold, and therefore companies utilise such data for commercial purposes. At the same time, the surveillance powers and the collection of personal data have increased among
