In this article, numerical simulations have been conducted on the heat transfer effect of dimple/protrusion layouts of a pin-finned wedge duct. Conjugate heat transfer calculations are further performed to investigate the cooling effect of modified schemes with dimples and protrusions added. Comparisons are carried out with a turbine second stage guide vane employed as the prototype. The dimple/pr

The enormous production and consumption of fossil-based plastics has caused severe environmental challenges such as pollution of the ocean, increased CO2-emissions, and various health problems. Many ofthese concerns are intimately connected to the use of fossil fuels in the production of polymers. For this reason, there is a considerable interest to develop bio-based monomers to mitigate some of t

A numerical method is utilized to investigate the converging angle effects on the flow structure and heat transfer of a pin fin wedge duct with dimples/protrusions. The studied converging angles are 0:0°; 6:3°; and 12:7° The results show that a pin fin-dimple wedge duct with larger converging angle produces higher heat transfer enhancement due to flow acceleration, increase of the impingement regi

This study investigated the impact of building orientations, typical layouts and positions at facades on daylight and sunlight availability in high-density residential areas in North-east China. Vertical daylight factor (including sky component and reflected component) and sunlight hours along the centre building facades in three typical models were calculated using Radiance and Autodesk Ecotect A

Neisseria gonorrhoeae is the etiological agent of gonorrhea, the second most common bacterial sexually transmitted infection worldwide. Reproductive sequelae of gonorrhea include infertility, ectopic pregnancy and chronic pelvic pain. Most antibiotics currently in clinical use have been rendered ineffective due to the rapid spread of antimicrobial resistance among gonococci. The developmental pipe

We consider a nonlinear vertex-reinforced jump process (VRJP(w)) on Z with an increasing measurable weight function w : [1, ∞) → [1, ∞) and initial weights equal to one. Our main goal is to study the asymptotic behaviour of VRJP(w) depending on the integrability of the reciprocal of w. In particular, we prove that if (Equation presented). then the process is recurrent, that is, it visits each vert

Supersonic combustion is a critical area of research for advancing high-speed flight technologies, particularly for the development of scramjet engines for hypersonic vehicles. This study employs Finite Rate Chemistry (FRC) Large Eddy Simulation (LES) together with different experimental techniques to study the supersonic flow and thermochemical processes in the Small Scale Flight Experiment (SSFE

Evaluating the trade interdependence among countries is the key to understanding critical metal minerals security. By constructing a novel interdependence network, this paper reveals a more comprehensive world hierarchy and risk system of critical metals, and focuses on the interdependencies between China and the US-led MSP countries before and after the Sino-US trade disputes. The results indicat

The aim of this article is to show that at the end of the 13th century there’s a change of approach to the sophistical syllogism, going from a definition based on its formal features to a definition based on its pragmatic features. The first position is put forward by Simon of Faversham, during the 1280s, probably during his stay in Paris. The second position is put forward by Radulphus Brito, the

I samband med att 34 småhusägare stämde småhusentreprenören Myresjöhus för fukt- och mögelproblem uppmärksammades termen utvecklingsfel, en ny typgodkänd byggmetod som senare visar sig vara problematisk. Samtidigt som det har framkommit att byggbranschen inte har någon tradition att göra utförliga tester innan en ny metod införs. Husägaren hamnar i kläm när varken garantin eller byggfelsförsäkring

Ny forskning bidrar till ökad förståelse av allergiska reaktioner Allergi har ökat dramatiskt under de senaste åren. Det är därför högst väsentligt att få ökad kunskap om hur beståndsdelarna i immunförsvaret hos allergiska personer samspelar. Förekomsten av allergi har kommit att öka dramatiskt under de senaste åren och har blivit ett betydande problem för folkhälsan. Allergi drabbar en så stor dThe prevalence of allergic disease is continuing to increase worldwide, and it has even become a major concern in public health. Allergic reactions are developed to otherwise harmless substances and may be both life-threatening as well as discomforting for patients in their daily life. Therefore, a more detailed knowledge about how antibodies interact with allergens and effector cells in allergic
