P2_6 Surfin' Fury

In a short film called Kung Fury, the main hero uses a person as a surfing board. We investigated the force he would need to push himself forward based on the kinetic friction and drag force. The force ranges between -335.24 ± 6.87 N and -980.74 ± 6.87 N

P2_4 Not So Spontaneous Combustion

In the X-Files TV series, a man is injected with a chemical that freezes him. When defrosting, his bodystarts producing exothermic reaction that sets him on re. At normal metabolic rate, this reaction wouldtake at least 4 days 15 hours and 24 minutes. In the time scale of the show the energy required to heatthe body would be 9.9 x 105 W

P2_1 In a Blink of an Eye

The game World of Warcraft allows a mage to teleport a short distance in almost an instant. Based on the description of the spell, we calculated the acceleration of the mage as 82.86 ± 13.96g. We then compared the acceleration of the mage to those that people are able to survive in real life

P2_5 Jovian Gravitational Perturbations on Earth's Orbit

In a hypothetical situations in which the solar system contains varied masses of Jupiter, the orbit of the Earth may fall subject to considerable gravitational perturbations. With the aid of the Newtonian gravity simulator, Universe SandboxTM, the effects of these perturbations can be observed .The orbit is found alter by an approximate 30x106 km before being ejected from the solar system, at Jovian mass of 0.7 Mʘ

P2_2 Understanding Goku's Spirit Bomb

 Goku's iconic "Spirit Bomb" has aided the hero in difficult situations in the world of Dragon Ball. With the aid of a photon sphere model, we obtain a glimpse into the necessary requisites. By creating a hypothetical sun-sized SB, we find that a photon sphere would require 5x1042 humans and would span 1x108 episodes.

Health related quality of life in individuals at high risk of chronic liver disease: Impact of a community diagnostic pathway

Objectives: There is a lack of understanding of health related quality of life (HRQoL) in chronic liver disease (CLD). With the rising prevalence of alcohol and obesity driven CLD, and the increasing ability to screen for fibrosis, it is important to understand the impact of the diagnostic process for patients.Study design: Prospective cohort studyMethods: A cohort study conducted utilising the Nottingham Adult Liver Disease Stratification Pathway, UK. All patients referred as high risk for CLD (due to metabolic, alcohol or abnormal liver enzymes) completed the EQ-5D before diagnosis and at three and 12 months after. HRQoL was investigated by domain, CLD severity (transient elastography) and temporally.Results: 493 patients participated with 300 (60.9%) completing at least one follow-up HRQoL assessment.Pre-diagnosis the median (IQR) utility index was 0.75 (0.61-0.85) and visual analogue scale was 75/100 (60-90). The median utility index was significantly lower amongst those with advanced liver disease compared to those without at all time points (baseline 0.68 vs 0.77, three-months 0.65 vs 0.79, 12-months 0.69 vs 0.84, all

Modelling Rock Fracture Induced By Hydraulic Pulses

Soft cyclic hydraulic fracturing has become an effective technology used in subsurface energy extraction which utilises cyclic hydraulic flow pressure to fracture rock. This new technique induces fatigue of rock to reduce the breakdown pressure and potentially the associated risk of seismicity. To control the fracturing process and achieve desirable fracture networks for enhanced permeability, the rock response under cyclic hydraulic stimulation needs to be understood. However, the mechanism for cyclic stimulation-induced fatigue of rock is rather unclear and to date there is no implementation of fatigue degradation in modelling the rock response under hydraulic cyclic loading. This makes accurate prediction of rock fracture under cyclic hydraulic pressure impossible. This paper develops a numerical method to model rock fracture induced by hydraulic pulses with consideration of rock fatigue. The fatigue degradation is based on S–N curves (S for cyclic stress and N for cycles to failure) and implemented into the constitutive relationship for fracture of rock using in-house FORTRAN scripts and ABAQUS solver. The cohesive crack model is used to simulate discrete crack propagation in the rock which is coupled with hydraulic flow and pore pressure capability. The developed numerical model is validated via experimental results of pulsating hydraulic fracturing of the rock. The effects of flow rate and frequency of cyclic injection on borehole pressure development are investigated. A new loading strategy for pulsating hydraulic fracturing is proposed. It has been found that hydraulic pulses can reduce the breakdown pressure of rock by 10–18% upon 10–4000 cycles. Using the new loading strategy, a slow and steady rock fracture process is obtained while the failure pressure is reduced
