The reception of Amadis changes in the eighteenth century, with a play (Granville’s The British Enchanters (1706) ) and an opera (Handel’s Amadigi di Gaula (1715) ) presenting the romance for theatrical consumption and emphasizing its overt spectacularism in a revivified Amadisian aesthetic. In a parallel development, Amadis was mined by Shakespearean editors, Hispanists, and literary historians such as Isaac Reed, John Bowle, and Thomas Warton as indicative of early modern taste and a means of elucidating the works of Cervantes and Shakespeare. The chapter closes with an account of the ‘spectral’ relationship of Amadis to early Gothic fiction, arguing that the ‘ancient romances’ invoked in the preface to the second edition of Walpole’s The Castle of Otranto (1765) are none other than the libros de caballerías, and showing how Lewis’s The Monk (1796) takes the traditions of peninsular ‘fancy’ in an entirely new direction.

Atmospheric correction is a fundamental process to remove the atmospheric effect from the top-of-atmosphere level. The atmospheric correction algorithm developed by the Korea Institute of Ocean Science and Technology employs a near-infrared (NIR) water reflectance model to deal with non-negligible NIR water reflectance over turbid waters. This paper describes the NIR water reflectance models using visible bands of the Second Geostationary Ocean Color Imager (GOCI-II). Whereas the previous GOCI uses the 660 nm band to estimate NIR water reflectance (SR660), GOCI-II uses additional 620 and 709 nm bands, which improves estimation of NIR water reflectance. We developed two reflectance models with the additional bands based on a spectral relationship of water reflectance (SR709) and a spectral relationship of inherent optical properties (SRIOP) from red to NIR wavelengths. A preliminary validation of these two reflectance models was performed using both simulations and an in situ dataset. The validation result showed that the mean absolute percentage error of the SR709 model compared with SR660 was reduced by approximately 6% and 10% at 745 and 865 nm, respectively. Moreover, the mean absolute percentage error of the SRIOP model compared with SR660 was reduced by approximately 12% and 16% at 745 and 865 nm, respectively. Note that SR709 produces the most accurate result when there is only one sediment type, and SRIOP shows the most accurate result when various sediment types exist. Users will be able to optionally select the appropriate NIR water reflectance models in the GOCI-II atmospheric correction process to enhance the accuracy of aerosol reflectance correction over turbid waters.

Meteorological Effects

This study was made to investigate the relationship of surface meteorological data and corresponding surface refractive indices to radio field strengths in the FM frequency band. For meteorological observations during which the wind speeds were equal to or greater than 10 mph, and when fronts, low overcast clouds (less than 5000 ft), rain, thunderstorms and fogs were excluded, a 0.70 correlation coefficient was found between hourly surface refractive index and hourly median field strength over a Washington-Richmond path at a frequency of 96.3 Mc.

The Relationship

The article describes a method based on the relationship of the integral index of refraction of air with its integral altitude gradient. The refractive index N and its altitude gradient dN / dH are proportional to each other under conditions of limited atmospheric height. It has been established that the gradient of the refractive index can be found by the index itself with a known coefficient of coupling between them. Wherein, it is easy to find the gradient by the angle of complete refraction. Results of experimental studies and recommendations for its use are given. A correlation analysis of the results of synchronous measurements was performed.

Polynuclear Aromatics

With a goal to identify, and ultimately removing from the oil fraction, the carcinogenic components, an oil fraction oil has been analyzed into a main three hydrocarbon groups, paraffins, aromatics, and polycyclic saturates. A multi-stage adsorption apparatus has been used. Four units of 300 g alumina each seems to be sufficient for removing the polynuclear aromatics from 75 g of an oil fraction boiling between 365-375 °C from Qurna crude oil. The usefulness of the ternary diagram for analyzing the oil fraction to the three hydrocarbons groups has been studied and verified. An experimentally based linear relationship of density and refractive index was established to enable of identifying the composition of an oil fraction using the values on refractive index alone. Separation of uncontaminated paraffins requires higher adsorbent/ oil ratio and/or more significant number of adsorption units. Ensuring no overloading of the adsorbent was essential for the separation.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.
