Intern experience with William F. Guyton & Associates: an internship report
No full textIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesThis report is a review of the author's experience as an intern with
William F. Guyton & Associates. William F. Guyton & Associates is a consulting
groundwater hydrology firm with offices in Austin and Houston, Texas. The intern worked at the
main office in Austin for the duration of the internship. The author worked on a variety of
projects during the internship. These projects encompassed general groundwater studies,
computer simulation, technical analyses of aquifer parameters, and inspection of water well
construction and testing. General groundwater studies involved the collection of water well
construction and chemical analyses data. The author wrote several computer codes to handle
basic computations, and the author used several existing finite difference codes to simulate
groundwater movement. The technical analyses of pumping test data were analyzed by the author
to determine aquifer parameters. The field work involved on-site inspection of water well
construction and involved quality control of the pumping test after construction. The author
interacted with various agencies of the state and federal government. This interaction was
necessary to many of the projects. The collection of water well data and the use of the finite
difference codes gave the author the opportunity to obtain knowledge of the daily operations
of these agencies

The long-wavelength view of GG Tau A: rocks in the ring world
No full textWe present the first detection of GG Tau A at centimetre wavelengths, made with the Arcminute Microkelvin Imager Large Array at a frequency of 16 GHz (λ = 1.8 cm). The source is detected at >6 σrms with an integrated flux density of S16GHz = 249 ± 45 µJy. We use these new centimetre-wave data, in conjunction with additional measurements compiled from the literature, to investigate the long-wavelength tail of the dust emission from this unusual protoplanetary system. We use an MCMC-based method to determine maximum likelihood parameters for a simple parametric spectral model and consider the opacity and mass of the dust contributing to the microwave emission. We derive a dust mass of Md ~ 0.1 Msun, constrain the dimensions of the emitting region and find that the opacity index at λ > 7 mm is less than unity, implying a contribution to the dust population from grains exceeding ~4 cm in size. We suggest that this indicates coagulation within the GG Tau A system has proceeded to the point where dust grains have grown to the size of small rocks with dimensions of a few centimetres. Considering the relatively young age of the GG Tau association in combination with the low derived disc mass, we suggest that this system may provide a useful test case for rapid core accretion planet formation models

The emergence of mercantilism as a reaction against Muslim power: some of the evidences from history
No full textIn the early modern period, changing attitude of Medieval Europe towards trade as an outcome of encounter with Muslim scholars and rulers and consequently emergence of 'mercantilism' was a turning point in the history of economic thought. The paper documents evidences which prove that initially mercantilism was a reaction against Muslim powers. In the rise of mercantilism, discovery of the New World is considered a significant factor. The main objective before explorers and pioneers of mercantilism was to strengthen their governments through the acquisition of precious metal to regain the Holy Places, defeat the enemy, check the expanding power of Muslim rivals and spread Christianity. However, later it ended up in an effective economic movement.Mercantilism; History of Economic Thought; Medieval Economic History.
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
Triple F-a comet nucleus sample return mission
No full textThe Triple F (Fresh From the Fridge) mission, a Comet Nucleus Sample Return, has been proposed to ESA's Cosmic Vision program. A sample return from a comet enables us to reach the ultimate goal of cometary research. Since comets are the least processed bodies in the solar system, the proposal goes far beyond cometary science topics (like the explanation of cometary activity) and delivers invaluable information about the formation of the solar system and the interstellar molecular cloud from which it formed. The proposed mission would extract three sample cores of the upper 50cm from three locations on a cometary nucleus and return them cooled to Earth for analysis in the laboratory. The simple mission concept with a touch-and-go sampling by a single spacecraft was proposed as an M-class mission in collaboration with the Russian space agency ROSCOSMOS. © The Author(s) 2008
Perception of market and pricing among the sixteenth century Muslim scholars
No full textThe present paper investigates the perception of market and mechanism of pricing among the sixteenth century Muslim scholars, a period hitherto unexplored. In the commencement it briefly states the insufficient attention that the subject of market – the most fundamental element of Economics – has received in the conventional economics. To set a proper perspective it examines the situation in the Islamic tradition in earlier centuries before it studies the understanding of market and pricing among the Muslim scholars of the study period. It also deals with their stand regarding the price regulation. For comparison purpose, it examines the treatment of market and pricing in the work of their contemporary Western scholars. The paper ends with a note on 'just price', one of the most important economic concepts in the medieval period.Market, Pricing Mechanism, Economic Thought,Just price.
