Applications of General-Purpose Computational Fluid Dynamics to a Plasma Propulsion System

Posted Leave a commentPosted in Physics

This project looks at the application of general-purpose CFD to two plasma propulsion engines. Verification against experimental data for a 200 kW engine was undertaken, achieving similar thrust levels and jet exhaust divergence angles. A scaled-up 30 MW engine, capable of interplanetary travel, showed similar operating behaviour to the test engine. The increased seventy-fold thrust […]

Observing the Mpemba effect over a range of initial temperatures of bodies of water.

Posted Leave a commentPosted in Physics

Abstract: This study was conducted in an effort to confirm or deny the existence of the Mpemba effect. The Mpemba effect states that when identical bodies of water at two different temperatures are exposed to a physical cooling agent, the body with a higher starting temperature will cool faster than its counterpart. The experiment was […]

Orange You Glad You Aren’t A Bird?

Posted Leave a commentPosted in Biology

Abstract The wide-ranging adaptations of birds has astounded scientists for many years and the crested auklet (Aethia cristatella) is no exception. Aside from its physical ornamentation and vocalisations, the auklet’s citric plumage-odour is one of its most well-known characteristics. The tangerine-like secretion is used in courtship displays as well as acting as an ectoparasite repellant, […]

Airborne Microplastics: A Global Issue With Implications For Human Health

Posted 1 CommentPosted in Earth Science, Environment

Abstract Plastic production has increased significantly over the past few decades and has impacted the environment in a negative way. Plastic products have the ability to break down into smaller particles less than 5 mm in size, known as microplastics, which can accumulate in a variety of places such as food and water sources. Recently, […]

Exploration of whether human colonisation is possible within our solar system

Posted Leave a commentPosted in Astrophysics

Abstract With the advancement of technology and scientific understandings, humans have been able to investigate many different astronomical bodies in outer space. In this review report, I explore some of the many worlds of our solar system in which humans could potentially colonise in future. It was Professor Michelle Dougherty, from the Imperial College London, […]

The Effect of Climate Change on the Distribution of Malaria in Africa

Posted Leave a commentPosted in Climate Change, Earth Science, Environment

  Abstract Malaria, an infectious disease transmitted by Anopheles mosquitoes, kills over 400,000 people each year. Of these 400,000 deaths, sixty-seven percent are children under the age of five [1]. The Anopheles mosquitoes can host five different species of malaria which infect humans [2]. This review mainly discusses the most lethal species, Plasmodium falciparum (P. […]

CORAL REEFS IN DANGER: THE THREATS, THE CONSEQUENCES, THE FUTURE

Posted Leave a commentPosted in Earth Science, Environment

BY: MADELEINE HSU ABSTRACT This article discusses coral reefs, the danger and threats they are facing, and how different marine animals and plants are being affected by factors like climate change, coastal development, and more.  This article also considers the possible restoration techniques used to rehabilitate coral reefs, as well as some of the governmental […]

The science of interaction and decision-making: Game Theory

Posted Leave a commentPosted in Mathematics

From the very beginning, we have tried to predict the future. Prediction is a messy business, and astrologers are seldom genuine. However, scientifically speaking, prediction is absolutely essential. From weather to strategic interactions, prediction is present everywhere. It is often impossible to predict complex, real-life phenomena using simple mathematical equations. We need a new concept […]

The Truth About Lying Under the Machine: Determining the Accuracy of Lie Detectors

Posted Leave a commentPosted in Biology, Neuroscience

Gopiga Dass Abstract From movies to real life, polygraph machines, otherwise known as lie detectors, have been used as a means to seek the truth since 1921[1]. However, the legitimacy of these machines has been long questioned in the scientific community. The purpose of this experiment is to determine the accuracy of polygraph machines by […]
