Apparent relationship between solar sector boundaries and 300-millibar vorticity: Possible explanation in terms of upward propagation of planetary-scale waves

The correlations between the solar sectors and large-scale atmospheric vorticity in the lower atmosphere reported earlier are of interest since the solar-sector data appear to be independent of any terrestrial influences. It is shown that even these solar data may be affected by geomagnetic properties; a method for removing such influences is suggested

Complete families of linearly non-degenerate rational curves

We prove that a complete family of linearly non-degenerate rational curves of degree $e > 2$ in $\mathbb{P}^n$ has at most $n-1$ moduli. For $e = 2$ we prove that such a family has at most $n$ moduli. It is unknown whether or not this is the best possible result. The general method involves exhibiting a map from the base of a family $X$ to the Grassmaninian of $e$-planes in $\mathbb{P}^n$ and analyzing the resulting map on cohomology.Comment: 14 page

Low-density polybenzimidazole foams for thermal insulation and fire protection

Fire-resistant and nonsmoking foam can be prepared in desirable density range of 24 to 50 kg/cu m by controlled thermal crosslinking of polybenzimidazole prepolymer. Reproducible foams of specific density can be produced by controlling volative content and melting temperature of prepolymer

Interpretation of Cerebral Dynamic Perfusion Studies

As stated earlier, increased, decreased, or no change in perfusion does contribute to the differential evidence in the diagnosis of cerebral lesions. For example, a 40-year-old man developed right-sided symptoms over a period of several months. The static images revealed an area of increased activity of the left cerebral hemisphere, limited to the cortex, and correlated with the configuration of the rolandic branch of the left-middle cerebral artery. From the static images the lesions was interpreted as a possible arteriovenous malformation, or as a lesser possibility, a progressive stroke. The dynamic study demonstrated early concentration of radioactivity in the correct location that persisted through the dynamic sequence and did not wash out. This evidence suggested a neoplasm, probably an enplaque meningioma that was found at subsequent surgery

The Characteristics of Underground Utility Repairs Made in Asphaltic Roadways – Comparing the Use of Grade D Aggregate as a Viable Backfill Option

Abstract Given that most utilities are located beneath public right of ways, it is difficult to perform repairs to the utility without significantly disturbing the existing roadway. Currently there are several standard orders of procedure that deal with small-scale repairs on asphaltic surfaces. This study investigates the use of Grade D Aggregate as a backfill during a utility repair versus the condition of the repair. Five East Tennessee utilities provided a total of 60 utility repair locations over three years of age; 30 of which incorporated Grade D Aggregate and 30 incorporated #57 Stone. The Tennessee Department of Transportation specifies a smoothness criterion of the roadway to regulate any deviation of the surface of the roadway greater than ¼ inch over a 12-foot span. The parameters measured during this study include smoothness, condition of the asphalt topcoat, adjacent stress cracking, depth of repair and disturbed surface area. Multiple linear regression and analysis of variance tests were used to analyze the results. Results suggest that there is no difference between using and not using Grade D Aggregate except with failures of one inch or greater. The results also suggest that there is little to no relationship between roadway characteristics and the performance of the repair except with failures one inch or greater. There is a correlation between slope and failures that had a deviation of one inch or greater. The results suggest that Grade D Aggregate performs better when significant failures occur. Recommendations include implementation of a cutback area, development and implementation of installation guidelines within the municipality, and implementation of a maintenance program that will address the repair cut failures in a timely manner

Summer 2015 GIS Analyst Internship at the Connecticut Department of Energy & Environmental Protection, Old Lyme, Connecticut

I worked as the Geographic Information Systems (GIS) Internee for the Connecticut Department of Energy & Environmental Protection (CT DEEP) from May 18, 2015 through August 14th of the same year. I was stationed at the Old Lyme Field office and worked under the direct supervision of Deb Pacileo, my boss and GIS analyst for CT DEEP. My function in the agency was similar to my supervisor\u27s as I had no single project that dominated my time, but was given a multitude of projects to create, edit, oversee, and produce. Some of these project included editing python scripts of former interns\u27, creating a database for trawl survey data input, and finalizing maps to be shown at a CT DEEP board meeting. The CT DEEP internship was important to my development as a GISDE student as it provided insight into how federal agencies might typically use geospatial software on a day to day basis. This report is a relation of my time at CT DEEP and my opinions on the strengths and weaknesses of the internship position
