Current Status of the Norman Site, 34WG2

As defined by Finkelstein in his description of excavations at the site, the Norman site currently is completely located within the waters of Fort Gibson Reservoir, a U.S. Army Corps of Engineers (COE) lake on the Grand (Neosho) River in northeastern Oklahoma. Due to a combination of archeological excavations at the site during the 1930s and 1940s, pothunting, large-scale earthmoving activities associated with the construction of a nearby highway bridge, and approximately 50 years of wave action and seasonal inundation by Fort Gibson Reservoir, portions of Mounds I-1 and I-2 are all that remain of the Norman site

Projective equivalence of ideals in Noetherian integral domains

Let I be a nonzero proper ideal in a Noetherian integral domain R. In this paper we establish the existence of a finite separable integral extension domain A of R and a positive integer m such that all the Rees integers of IA are equal to m. Moreover, if R has altitude one, then all the Rees integers of J = Rad(IA) are equal to one and the ideals J^m and IA have the same integral closure. Thus Rad(IA) = J is a projectively full radical ideal that is projectively equivalent to IA. In particular, if R is Dedekind, then there exists a Dedekind domain A having the following properties: (i) A is a finite separable integral extension of R; and (ii) there exists a radical ideal J of A and a positive integer m such that IA = J^m.Comment: 20 page

Distribution Of Mayfly Nymphs (Ephemeroptera) In Streams Of Dallas County, Texas

Although mayflies are of common occurrence in the Southwest, but little work has been done here on them. Most investigations on this group of insects have been done in New York, the Great Lakes Region, and Canada. Some work has been done in the Rocky Mountain area, and also along the Atlantic coast. Berner (1950) has published an extensive work on the mayflies of Florida. This is the first major work in this field since the book, Biology of Mayflies, by Needham, Traver, & Hsu (1935). Besides these, many minor papers on this group have appeared; but for Texas only a few scattered records are available

INDOT Asset Management in 2016

One of INDOT’s performance goals for 2015–2016 is to “take care of what we have.” With that goal in mind, INDOT has been working with staff to implement a plan that maintains steady improvement in pavement and bridge quality and to ensure a commitment to safety, which we will outline in this session

Thinking Globally About Universities and Extension: The Convergence of University-Based and Centralized Extension Systems in China

The U.S. university-based extension system model has been successful nationally, but not adopted globally. Various historical factors rendered the U.S. system a less attractive option for emerging post-WWII nations. However, current changes in education and extension landscapes are creating new opportunities for the globalization of U.S. Extension. Specifically, both the U.S. and Chinese extension systems now face the common challenge of delivering meaningful university-based extension under shifting conditions. This commonality creates opportunities for exploring long-term, synergistic university-based extension systems and potentially achieving associated benefits worldwide

Off-Design Performance Analysis of a Solid-Oxide Fuel Cell/Gas Turbine Hybrid for Auxiliary Aerospace Power

A solid-oxide fuel cell/gas turbine hybrid system for auxiliary aerospace power is analyzed using 0-D and 1-D system-level models. The system is designed to produce 440 kW of net electrical power, sized for a typical long-range 300-passenger civil airplane, at both sea level and cruise flight level (12,500 m). In addition, a part power level of 250 kW is analyzed at the cruise condition, a requirement of the operating power profile. The challenge of creating a balanced system for the three distinct conditions is presented, along with the compromises necessary for each case. A parametric analysis is described for the cruise part power operating point, in which the system efficiency is maximized by varying the air flow rate. The system is compared to an earlier version that was designed solely for cruise operation. The results show that it is necessary to size the turbomachinery, fuel cell, and heat exchangers at sea level full power rather than cruise full power. The resulting estimated mass of the system is 1912 kg, which is significantly higher than the original cruise design point mass, 1396 kg. The net thermal efficiencies with respect to the fuel LHV are calculated to be 42.4 percent at sea level full power, 72.6 percent at cruise full power, and 72.8 percent at cruise part power. The cruise conditions take advantage of pre-compressed air from the on-board Environmental Control System, which accounts for a portion of the unusually high thermal efficiency at those conditions. These results show that it is necessary to include several operating points in the overall assessment of an aircraft power system due to the variations throughout the operating profile
