The effect of electronic cookery upon the appearance and palatability of a yellow cake

The magical quality of electronic cookery was first sensed by Percy Spencer of the Raytheon Manufacturing Company when he became conscious that the melting of a chocolate bar in his pocket was caused by its proximity to a magnetron tube. From such a beginning, the Radarange, the first electronic range, was developed and manufactured. This range, an institution-type, was first used on an experimental basis for approximately ten years. In 1954 the electronic range came on the market for commercial use by public eating places. In the latter part of that same year, a home-style electronic range was introduced to the consumer by the Tappan Stove Company. To date, four companies - Kelvinator Division of American Motors Corporation, RCA Whirlpool Corporation, Westinghouse Electric Corporation, and Tappan Stove Company - have purchased the rights to the use of the magnetron, source of microwave energy, from the Raytheon Manufacturing Company

The world of Carson McCullers

The fiction of Carson McCullers depicts a distinct, unique world characterized by its emphasis on the bizarre and grotesque. It is a world inhabited by freaks and outcasts whose experiences, removed from the realm of the ordinary, are violent, abrupt, and terrible. Her heroes, unacceptable and alienated by their freakishness, live in a world made unendurably lonely by the failure of love and communication. The horrible spiritual isolation inevitable in a world where love fails and dialogue ends in frustration is one of Carson McCullers' favorite themes, and she persistently develops it in all her writing. It is the nature of this theme that governs her choice of the unusual and grotesque. Throughout all her work Carson McCullers, trying to teach about the nature of love and the attendant loneliness and pain, depends extensively on the use of symbolism. It is because the expression of her major themes is predominantly symbolic that the freaks and outcasts and their experiences have a meaning beyond the realistic, narrative level of the novel

The legal aspects of disciplinary suspension and expulsion practice and policy at major tax-supported colleges and universities in South Carolina

The administration of discipline at tax-supported colleges and universities has seen great change and evolution during the past thirty years, with significant case law and authoritative literature emerging from the landmark Dixon case of 1961. The major purpose of this study was the assessment of disciplinary procedures and policies used by the 11 major tax-supported colleges and universities in South Carolina, and an analysis of those procedures and policies in light of prevailing case law and authoritative opinion. The study was developed through descriptive and historical analyses of case law, legal trends, and authoritative legal and educational opinion regarding disciplinary due process and related issues at tax-supported institutions. Descriptive data and information concerning disciplinary practices at the eleven colleges and universities were collected and analyzed in terms of consensus findings resulting from the analysis of case law and expert opinion. The resulting analysis provides institutional disciplinary administrators with an assessment of their institutions' disciplinary policies and procedures, and guidelines for the retention, modification, and addition to their practices

Measuring M2 values for on-wafer vertical cavity surface emitting lasers

We report on M2 measurements taken for on-wafer vertical cavity surface emitting lasers (VCSELs). We measured M2 for oxide-confined VCSELs and photonic crystal (PhC) VCSELs of similar lasing aperture sizes

Characterization of Single-Mode Vertical Cavity Surface-Emitting Lasers

A high-quality single-mode beam is desirable for the efficient use of lasers as light sources for optical data communications and interconnects, however there is little data which characterizes operating ranges and near-field beam qualities of Vertical Cavity Surface Emitting Lasers (VCSELs), which has resulted in a lack of analysis of these devices. Measures of beam quality include beam-quality factor (M2 ), Side-Mode-Suppression-Ratio (SMSR) and RMS linewidth. M2 is a measurement of how closely the beam is to an ideal Gaussian. SMSR is the difference, in dB, between the amplitude of the primary peak and the amplitude of the next highest peak of the output spectrum, with single-mode operation defined by a SMSR \u3e 30 dB. RMS linewidth is a second moment calculation involving the power spectral density, where smaller RMS linewidth indicates higher beam quality. Utilizing a novel vertical M2 setup in which on-wafer VCSEL M2 can be measured, a study was conducted on the relation between M2 , SMSR and RMS linewidth, for various oxide-confined VCSELs of varying aperture sizes and Photonic Crystal (PhC) VCSELs of varying aperture sizes and photonic crystal configurations. First, the operating range of the VCSEL was determined utilizing a Semiconductor Parameter Analyzer to obtain the LIV characteristics. Along with this measurement, spectral data was collected using an Optical Spectrum Analyzer at several key operating points, which allowed the RMS linewidths and SMSRs of the devices to be calculated at these points. The novel beam-profiler setup was used to measure the device’s M2 . Initial results show a strong correlation between the measures of beam quality, with increasing SMSR, corresponding to M2 values closer to 1, and single-mode operation characterized by a M2 of less than 1.5. A strong correlation between RMS linewidth and M2 was also seen, with increasing RMS linewidths corresponding to an increase in M2
