Quinoxaline derivatives exhibit a wide range of biological activities and electron transport properties. The presence of electron withdrawing quinoxaline ring has been used in π-conjugated structures to fabricate the OLED materials. In the present investigation, vinyl benzaldehyde capped quinoxaline derivatives were synthesized using 6-methyl-2,3difurylquinoxaline with terephthaldicarboxaldehyd...

Cognitive science research, much of it supported by the Office of Naval Research, is bringing about a scientific revolution in our understanding of the human operator. It is yielding computational theories of human cognition and perceptual/motor activity that provide precise quantitative predictions of important variables such as the times required to complete tasks or to learn them in training...

The literary world has been delirious with excitement since the announcement in February that a second novel by Harper Lee had been “found” and was to be published. To Kill a Mockingbird [3] was Harper Lee’s first (and until now only) novel published in 1960, winner of the 1961 Pulitzer Prize, and certainly one of the most beloved novels in American history. Having recently read Go Set a Watchm...

Humic acids are the most active components of soil organic matter and have been shown to have an hormone-like activity thus stimulating plant growth. The objective of this work was to verify the quantitative and qualitative yield responses of the table grape cv. Italia after the application of a humic acid at various phenological stages. The humic acid used in this study has been extracted from...

Futsal is a FIFA sanctioned form of 5-a-side football. It is controlled by two referees who run up and down the touchlines either side of the pitch ensuring the laws of the game are enforced. The match is played over two halves of 20 minutes, with the clock being stopped every time the ball goes out of play; so each half can last up to 40 minutes including stoppage time. To date there has been ...

The marriage of literature and science might not be possible strictly speaking, but a marriage of humanities with philosophy, psychology, religion, ethics, ecology, and social studies, for instance, might well work, as a close analysis of some medieval narratives will illustrate. This paper intends to demonstrate once again what the humanities could truly mean, insofar as the discussion will no...

In this research, a new magnetic nanocatalyst CuFe2O4@Si-Imid-PMo containing acidic ionic liquid based on imidazolium cation and phosphomolybdic acid anion immobilized on CuFe2O4@SiO2 magnetic nanoparticles was prepared and characterized using FT-IR, EDX, SEM, and VSM techniques. Then, the catalytic activity of CuFe2O4@Si-Imid-PMo was evaluated in the synthesis of 2,4,5-trisubstituted imidazole...

This paper surveys the markets for financial transmission rights (FTRs) around the world. FTRs are used to hedge the costs associated with transmission congestion. Currently these rights are in use in PJM, New York and New England. A variant of financial transmission rights, which has both a physical and a financial aspect, was introduced in California in 2000. Similarly, flowgates were introdu...
