Semiconductor optical amplifiers in avionics

RSOAs have been demonstrated to operate within a WDM PON architectures over a >;60nm wavelength range with large path loss capabilities. Two RSOAs enable contiguous operation over the S, C and L bands; results indicate clearly that WDM architectures suitable for avionics with a PLC of >;25dB are possible with only two devices. Performance at extended temperature ranges will be reported later in detai

Chinese Climate Leadership: Feign or Future?

As industrial civilization confronts the devastating consequences of global climate change, the difficult choices surrounding its solutions have only become more complicated following the election of President Donald Trump and his recent declaration of intent to exit the Paris Climate Accord. This paper analyzes whether China is prepared and credible to fill the void left by the US abdicating its role as global climate leader by focusing on whether China’s domestic efforts are sufficient to project a sense of both willingness and capability to be the world’s foremost authority on climate change policy. This article ultimately determines that China is both ready and willing to act as the preeminent climate power, despite imperfections in domestic energy and environment policy

The Defense Industrial Base: How Idiosyncratic and Historical Influences Dictate Its Future

The Defense Industrial Base is the river from which American military dominance flows. However, the Industrial Base is just as—if not more—vulnerable to floods and droughts as a typical industry. Tracing the sector’s historical and economic foundations helps illuminate existing gaps and strengths that can present strategic challenges and benefits. This paper aims to connect those trends to existing and future capabilities. Although the Industrial Base will take time to fill the demands of the new $700-plus billion defense budget, the more concerning strategic issues are that the budget, and subsequently, the Industrial Base are leaving a gap in medium-term capability development and that discretionary budgets are likely to be overwhelmed by mandatory spending in the coming decades

Fossil-Fueled Discourse

As industrial civilization confronts the realities of devastating global climate change and the local environmental catastrophes precipitated by coal, oil, and natural gas extraction, this paper moves away from mainstream analyses of demand-side choices and instead considers how miners and rig workers make decisions surrounding the ethicality of their work. This article considers corporate publications including investor and sustainability reports and company-sponsored employee magazines, industry magazines, and news sources in top-producing fossil fuel producing localities in the United States. A discursive analysis of this set of publications uncovers a dense rhetorical lattice of misinformation and disinformation surrounding fossil fuel workers. This essay finds that company publications develop a foundation for engendering positive feelings and loyalty towards one’s employer and that industry magazines construct a sense of identity centrally determined by being a fossil fuel extractor, but no relationship is found in local newspapers

The Effects of X-rays and Beta Rays (Tritium) on the Growth of \u3cem\u3eRickettsia mooseri\u3c/em\u3e and \u3cem\u3eRickettsia akari\u3c/em\u3e in Embryonate Eggs

The growth of Rickettsia mooseri was accelerated and quantitatively increased in embryonate eggs containing tritium oxide at levels of 180, 90, and 45 mc./egg during the growth period. The eggs of a group containing 22.5 mc./egg showed only a slight increase in the rate of growth of organisms; the infections in the eggs of a group given 11.2 mc./egg did not differ significantly from those of the control group. On the other hand, growth of R. akari was inhibited in embryonate eggs containing tritium oxide at levels of 180, 90, and 45 mc./egg, and partially inhibited in groups containing 22.5 and 11.2 mc./egg. The patterns of growth of R. mooseri and of R. akari exposed to tritium oxide for 6 hours prior to inoculation into embryonate eggs did not differ significantly from that of the control group

Liquid vapor equilibrium in nucleate and film boiling

Liquid vapor equilibrium data were obtained for several solutions and azeotropes under both nucleate and film boiling. The data were invariant between the two boiling regimes indicating that both nucleate and film boiling are equilibrium vaporizations rather than either diffusional or bulk vaporizations. Boiling heat transfer versus temperature data were taken in nucleate and film boiling for the solutions and azeotropes and for several pure liquids. The critical heat flux for methyl alcohol-benzene solutions rose sharply at first and then more moderately with increasing alcohol concentration. The critical heat flux was pratically constant regardless of concentration in ethyl alcohol-benzene solutions. Photographs of nucleate and film boiling were taken to illustrate the differences between the two boiling regimes. The photographs were consistant with previously published work

'The Devil to Pay' and its influence on eighteenth-century German Singspiel

The premiere of Christian Felix Weisse's Singspiel Der Teufel ist los, oder die verwandelten Weiber was presented at the theatre in Quandts Hof, Leipzig, on the 5th May 1766. There it won immediate success which soon spread throughout the German speaking world. The . ensuing craze for similar entertainments played an important part in the development of the genre. This was not an original piece, however, and its success was dependent upon the skill with which Weisse had contrived to combine two quite different styles. This he achieved by means of Charles Coffey's The Devil to Pay, or the Wives metamorphosed, an English ballad-opera, and Michel Jean Sedaine's Le diable a quatre, written in the form of a French opera comique. The purpose of this study is to examine Coffey's ballad-opera together with those adaptations that enabled Weisse to develop the Singspiel into a form which stood as a model for many years afterwards

Milk cooling

Milk and other dairy products are among our most important foods. The growing population in the larger towns and the increase in the use of milk means that new problems will always arise in the production and handling of milk. This thesis is intended as a study in the problem of milk cooling. In preparing this thesis, references have been made to the latest investigations along the lines of milk cooling and in each case credit has been given to the writers and investigators whose material has been used
