A numerical, time domain solution for the response of a Gimbal supported gyro

This paper develops an algorithm to generate a numerical solution for the response of a gimbal supported gyro to arbitrary forcing functions and base motion, and includes the normal parasitic effects of bearing friction, viscous pivot damping, and pivot spring constants. There are relatively few restrictions on gyro and gimbal structure geometry. Solution accuracy is limited only by the computing machine accuracy; the algorithm being an explicit function of the input data. The algorithm is fast and requires only a moderate amount of computer memory --Abstract, page ii

A study of the physiology and gas limited growth of Methylococcus capsulatus

The results presented in this thesis have provided an understanding of gas limited growth, as well as an insight into the physiology of the methanotroph Methylococcus capsulatus (Bath). A theory of gas limited growth is presented which explains the experimentally observed dilution rate curves obtained during this investigation. Measurement and calculations of yield data are described and the problems encountered in these estimations are considered, particularly the transient effect of pHs additions on carbon dioxide production The maximum yield obtained was 0.65g. cells/g. of methane used. The rate of gas utilisation by the organisms was proportional to the partial pressure of the limiting gas entering the system. Cultures of Methylococcus capsulatus (Bath) grown on air/methane mixtures were oxygen-limited above 15% methane and methane limited below 4% methane. On occasions these cultures were sensitive to sudden increases in oxygen availability and would completely oxidise methane to carbon dioxide. Antifoam additions lowered An enclosed batch culture system was developed to enable changes in the gas and liquid phases to be monitored during growth. Nutrient-limited growth in batch cultures (linear growth) is described and typical growth curves presented, 0.1% v/v methanol did not inhibit growth of established cultures of Methylococcus capsulatus (Bath) but did inhibit methane oxidation. Methanol was used in preference to methane (demonstrated in batch and continuous culture) and was not detected in culture supernatants. Additions of 20 mM formate did not increase the yield of the organism grown on methane and nitrate mineral salts. The problems of growth on three nitrogen sources are discussed and the comparative yields on nitrate, ammonium and dinitrogen were respectively 0.48, 0.52 and 0.45 g. cells/ g. of methane used. Acetylene was found to be a potent specific inhibitor of methane oxidation. Ethane and ethanol inhibited methane- uptake and were oxidised to acetaldehyde which accumulated in the culture

Eastern Maine and the Rebellion: being an account of the principal local events in eastern Maine during the war

Introduction It has been our endeavor in these pages, to depict the scenes and incidents occuring at home, during the Rebellion, rather than the giving of a minute description of the varied experiences of the thousands, who marched away from Eastern Maine, at their Country\u27s call. We lay no claim to high literary merit, simply placing before you, in condensed form, the facts; believing that as the memories of the older readers are quickened, and the younger generation learn of the experiences of fathers and mothers, in their efforts to preserve the Union, all will find something of deep interest.

P1_9 Can You Get Into Space for Peanuts?

 Developing low cost space travel is a key issue since the retirement of the Shuttle. This paper looks at the feasibility of a mixture of toffee and peanuts in a low cost solid fuel rocket. It is found that this fuel mixture would lead to a mass ratio of about 54 which corresponds to a rocket consisting of 98% fuel and 2% remaining for the rocket structure and payload

P1_4 Could Bruce Willis Predict the End of the World?

This article is a follow-â€up to the paper Could Bruce Willis Save the World? where the feasibility of splitting an asteroid with a nuclear weapon is studied. In this article the possibility of spotting the asteroid with the Hubble Space Telescope upon a lucky image was researched. It was found the asteroid could have been spotted as far as away as 1.3210^14ð‘š

P1_7 Medical Nanobot Locomotion Methods within a Fluid

The following paper discusses the motion and mechanisms behind the motion of a nanoscale robot within a fluid and compares it to that of a larger object moving through the same fluid by considering the impeding forces to motion that the nanobot has to overcome. The fluid considered is water and it is found that the apparent viscosity of a fluid is highly dependent on the length scale of the object attempting to move through it with a nanoscale object experiencing a much larger viscosity compared to a macro scale object in the same fluid
