TL;DR: In this article, single carbon fibres 25 cm long have been strained at a rate of 0.1 cm/h and their electrical resistance monitored continuously, and three different grades of fibre, each from a different source, have been studied.
Abstract: SINGLE carbon fibres 25 cm long have been strained at a rate of 0.1 cm/h and their electrical resistance monitored continuously. Three different grades of fibre, each from a different source, have been studied (Table 1); values of Young's modulus were determined from tensile tests on individual fibres. The electrical resistance of the unstrained fibres varied from fibre to fibre even among fibres of the same grade. The variations within the grades appeared to be due to variations in the diameter of the fibres; mean values of resistance and diameter are given in Table 1.

TL;DR: In this article, the authors reported the discovery of a giant planet in microlensing event MOA-2011-BLG-322, which displays a clear anomaly induced by a second lensing mass, was inside the footprint of our second-generation micro-lensing survey, involving MOA, OGLE and the Wise Observatory.
Abstract: Global "second-generation" microlensing surveys aim to discover and characterize extrasolar planets and their frequency, by means of round-the-clock high-cadence monitoring of a large area of the Galactic bulge, in a controlled experiment. We report the discovery of a giant planet in microlensing event MOA-2011-BLG-322. This moderate-magnification event, which displays a clear anomaly induced by a second lensing mass, was inside the footprint of our second-generation microlensing survey, involving MOA, OGLE and the Wise Observatory. The event was observed by the survey groups, without prompting alerts that could have led to dedicated follow-up observations. Fitting a microlensing model to the data, we find that the timescale of the event was t_E=23.2 +/-0.8 days, and the mass ratio between the lens star and its companion is q=0.028 +/-0.001. Finite-source effects are marginally detected, and upper limits on them help break some of the degeneracy in the system parameters. Using a Bayesian analysis that incorporates a Galactic structure model, we estimate the mass of the lens at 0.39 +0.45/-0.19 M_sun, at a distance of 7.56 +/-0.91 kpc. Thus, the companion is likely a planet of mass 11.6 +13.4/-5.6 M_J, at a projected separation of 4.3 +1.5/-1.2 AU, rather far beyond the snow line. This is the first pure-survey planet reported from a second-generation microlensing survey, and shows that survey data alone can be sufficient to characterize a planetary model. With the detection of additional survey-only planets, we will be able to constrain the frequency of extrasolar planets near their systems' snow lines.

TL;DR: In this article, the equations for planar two-dimensional steady flow of an ideal dissociating gas are linearized, assuming small disturbances to a free stream in chemical equilibrium.
Abstract: The equations for planar two-dimensional steady flow of an ideal dissociating gas are linearized, assuming small disturbances to a free stream in chemical equilibriumAs an example of their solution, the flow past a sharp corner in a supersonic stream is evaluated and the variations of flow properties in the relaxation zone are found Numerical illustrations are provided using an ‘oxygen-like’ ideal gas and comparisons made with a characteristics solution The flow past a sharp corner can be studied in a conventional shock tube and it may be possible to verify the present theory experimentally In particular it may prove feasible to use the results to obtain a measure of the reaction rates in the gas mixture

TL;DR: The thermal degradation of bisphenol A-based epoxy resin (EP 274) cured with 4,4′-diaminodiphenyl methane (DDM) and with phthalic anhydride (PA) was studied using a radiochemical pyrolysis gas chromatography technique as discussed by the authors.
Abstract: The thermal degradation of a bisphenol A-based epoxy resin (EP 274) cured with 4,4′-diaminodiphenyl methane (DDM) and with phthalic anhydride (PA) was studied using a radiochemical pyrolysis gas chromatography technique Conclusive evidence for some of the degradation mechanisms of these resins was obtained by pyrolyzing samples containing various 14C-labelled groups and analyzing the products using this method

TL;DR: In this paper, the authors conducted a survey and literature review to investigate the impact of personal in-flight entertainment (IFE) services on passengers' satisfaction with airline services and found that while IFE is not among the primary factors affecting passengers' choice of airline, it contributes greatly to passengers satisfaction with the airline services.
