    In this paper the maximum acceleration on the ODST and the pod was found to be 4g-4g, with a braking thrusters force of 1410014100 N during the last 5050 m of descent. This deceleration brings the impact velocity of the pod to below velocity of 11 ms1^{-1}, should the braking thrusters fail to fire the pod will hit the ground with a velocity of 43.243.2 ms1^{-1} killing the trooper

    In this paper we consider a weapon system that fires a laser at an interplanetary vessel. We calculate the energy required to melt through a vessel’s armoured hull, of thickness 0.254 m, from a shot from a laser with a calibre of 16 inches. The energy required is found to be E = 34449 J. Using this energy, the recoil of the laser firing was calculated to be ρ = 1.15x10−4 kgms−1

    In this paper we calculate the minimum area and length of a dragon’s wing for it to be able to fly. The minimum area was calculated to be 224m^2 and the length was 35.6m

    In this paper we consider the maximum strength of Ash's Snorlax, from the Pokemon original TV series, this will occur when the Snorlax jumps as high as it can. The maximum height of the jump was calculated to be 41.8 m, the velocity it impacts the ground with is 28.1 ms^-1 and the momentum of the Snorlax when it hits the ground is 12,900 kgms^-1

    Comparison of shipbuilding and construction industries from the product structure standpoint

    Copyright © 2018 Inderscience Enterprises Ltd. The use of building information modelling (BIM) in construction compares to the use of product lifecycle management (PLM) in manufacturing. Previous research has shown that it is possible to improve BIM with the features and the best practices from the PLM approach. This article provides a comparison from the standpoint of the bill of materials (BOM) and product structures. It compares the product beginning of life in both construction and shipbuilding industries. The research then tries to understand the use, form and evolution of product structures and BOM concepts in shipbuilding with the aim of identifying equivalent notions in construction. Research findings demonstrate that similar concepts for structuring information exist in construction; however, the relationship between them is unclear. Further research is therefore required to detail the links identified by the authors and develop an equivalent central structuring backbone as found in PLM platforms

    This paper discusses the plausibility of the thruster in the Iron Man suit being used as weapons to push a human back. It was determined that the shock-wave produced by the change in temperature due to the thrusters would produce a force of 183183 kN on a person it was shot at, this would cause the person to accelerate at 26142614 ms2^{-2} killing the person

    Counteractive effects of antenatal glucocorticoid treatment on D1 receptor modulation of spatial working memory.

    RATIONALE: Antenatal exposure to the glucocorticoid dexamethasone dramatically increases the number of mesencephalic dopaminergic neurons in rat offspring. However, the consequences of this expansion in midbrain dopamine (DA) neurons for behavioural processes in adulthood are poorly understood, including working memory that depends on DA transmission in the prefrontal cortex (PFC). OBJECTIVES: We therefore investigated the influence of antenatal glucocorticoid treatment (AGT) on the modulation of spatial working memory by a D1 receptor agonist and on D1 receptor binding and DA content in the PFC and striatum. METHODS: Pregnant rats received AGT on gestational days 16-19 by adding dexamethasone to their drinking water. Male offspring reared to adulthood were trained on a delayed alternation spatial working memory task and administered the partial D1 agonist SKF38393 (0.3-3 mg/kg) by systemic injection. In separate groups of control and AGT animals, D1 receptor binding and DA content were measured post-mortem in the PFC and striatum. RESULTS: SKF38393 impaired spatial working memory performance in control rats but had no effect in AGT rats. D1 binding was significantly reduced in the anterior cingulate cortex, prelimbic cortex, dorsal striatum and ventral pallidum of AGT rats compared with control animals. However, AGT had no significant effect on brain monoamine levels. CONCLUSIONS: These findings demonstrate that D1 receptors in corticostriatal circuitry down-regulate in response to AGT. This compensatory effect in D1 receptors may result from increased DA-ergic tone in AGT rats and underlie the resilience of these animals to the disruptive effects of D1 receptor activation on spatial working memory.The authors’ research is funded by the Wellcome Trust (grant number 086871/Z/08/Z), the MRC (G0701500), a joint award from the MRC (G1000183) and Wellcome Trust (093875/Z/10/ Z) in support of the Behavioral and Clinical Neuroscience Institute at Cambridge University, and an MRC strategic award to the Imperial College-Cambridge University-Manchester University (ICCAM) addiction cluster (G1000018).This is the final version of the article.
