Effect Of Allyl Thiourea On Nickel Electrodeposition From Solution Containing Ammonia And Chloride, Ya-Ning He, Liang Yuan, Zhi-Ying Ding, Shi-Jun Liu

Journal of Electrochemistry

The effects of allylthiourea (ATU) concentration on the cathodic polarization behaviour, nucleation and surface morphology of nickel electrodeposited on the glassy carbon electrode from ammonia-ammonium chloride-water (NH₃-NH₄Cl-H₂O) solutions were investigated by cyclic voltammogry, cathodic polarization and current transient methods. The results revealed that the addition of ATU inhibited nickel deposition, which was enhanced with an increase in ATU concentration from 5 to 50 mg•L^-1. The initial deposition kinetics corresponded to a model including instantaneous nucleation and diffusion controlled growth. In the presence of ATU, the initial nucleation of nickel electrocrystallisation remained unchanged. …

Journal of Contemporary Water Research and Education

The Lower Mississippi River Basin (LMRB) is an internationally-important region of intensive agricultural crop production that relies heavily on the underlying Mississippi River Valley Alluvial Aquifer (MRVAA) for irrigation. Extensive irrigation coupled with the region's geology have led to significant aquifer decline. The response to the decline has been multi-faceted. Research related to three responses are highlighted: innovation in rice irrigation, on-farm reservoirs, and managed aquifer recharge. Irrigated rice grown in Arkansas, which is nearly 50% of annual U.S. rice production, accounts for a significant portion of aquifer withdrawal. As a result, strategies for using less water while maintaining rice …

Developmental Biology, The Stem Cell Of Biological Disciplines, Scott F. Gilbert

Biology Faculty Works

Developmental biology (including embryology) is proposed as "the stem cell of biological disciplines.” Genetics, cell biology, oncology, immunology, evolutionary mechanisms, neurobiology, and systems biology each has its ancestry in developmental biology. Moreover, developmental biology continues to roll on, budding off more disciplines, while retaining its own identity. While its descendant disciplines differentiate into sciences with a restricted set of paradigms, examples, and techniques, developmental biology remains vigorous, pluripotent, and relatively undifferentiated. In many disciplines, especially in evolutionary biology and oncology, the developmental perspective is being reasserted as an important research program.

Is The State Of The Air-Sea Interface A Factor In Rapid Intensification And Rapid Decline Of Tropical Cyclones?, Alexander V. Soloviev, Roger Lukas, Mark A. Donelan, Brian K. Haus, Isaac Ginis

Graduate School of Oceanography Faculty Publications

Tropical storm intensity prediction remains a challenge in tropical meteorology. Some tropical storms undergo dramatic rapid intensification and rapid decline. Hurricane researchers have considered particular ambient environmental conditions including the ocean thermal and salinity structure and internal vortex dynamics (e.g., eyewall replacement cycle, hot towers) as factors creating favorable conditions for rapid intensification. At this point, however, it is not exactly known to what extent the state of the sea surface controls tropical cyclone dynamics. Theoretical considerations, laboratory experiments, and numerical simulations suggest that the air-sea interface under tropical cyclones is subject to the Kelvin-Helmholtz type instability. Ejection of large …

. . . And Law?, John Henry Schlegel

Contributions to Books

Published as Chapter 18 in Searching for Contemporary Legal Thought, Justin Desautels-Stein & Christopher Tomlins, eds.

The locution “law and . . . (some other discipline)” implicitly asserts the primacy of legal doctrine and institutions narrowly conceived for coming to understand phenomena in which law takes a part. The ordinary story of American legal theory – formalism then realism then contemporary legal thought – can be understood to repeat the triumphalism implicit in “law and . . .” Of course, the story of American legal theory could possibly be read differently -- as a series of responses to the inability …

Cigarette Taxes And Illicit Trade In Europe Online Appendix, James Prieger, Jonathan D. Kulick

School of Public Policy Working Papers

Cigarettes are highly taxed in Europe to discourage tobacco use and to fund public-health measures to mitigate the harms from tobacco consumption. At higher prices some consumers substitute more toward illicit cigarettes. We find that raising prices in any one country would lead to substantial increases in the expected illicit market share and volume in that country. This appendix contains more complete information about the data and additional regressions to which the article published in Economic Inquiry (and also available in earlier form as School of Public Policy Working Paper 60) refers.
