A study of water quality in Baltimore Harbor

Baltimore Harbor is polluted by discharge of sewage and industrial wastes into tributary streams and peripheral waters. The Harbor is used extensively for navigation, industrial water supply, and recreation as well as for waste disposal. The degree of pollution varies from negligible in the principal fairway to severe in the innermost sections. Private industry discharges several hundred tons of acid materials daily and is also the principal source of organic pollution

EFFECTS OF ENERGY DEVELOPMENT ON AGRICULTURAL LAND VALUES

This paper uses multiple regression analysis to examine the effects of energy resource development on sale prices of agricultural land in western North Dakota. The findings suggest that energy resources development has exerted only modest upward pressure on agricultural land values in the northern Great Plains. The land market in this region remains dominated by active farmers who are purchasing farmland as a long-term investment, and energy development has not had a major impact on the structure of that market.Land Economics/Use, Resource /Energy Economics and Policy,

Use of inedible wheat residues from the KSC-CELSS breadboard facility for production of fungal cellulase

Cellulose and xylan (a hemicellulose) comprise 50 percent of inedible wheat residue (which is 60 percent of total wheat biomass) produced in the Kennedy Space Center Closed Ecological Life Support System (CELSS) Breadboard Biomass Production Chamber (BPC). These polysaccharides can be converted by enzymatic hydrolysis into useful monosaccharides, thus maximizing the use of BPC volume and energy, and minimizing waste material to be treated. The evaluation of CELSS-derived wheat residues for production for cellulase enzyme complex by Trichoderma reesei and supplemental beta-glucosidase by Aspergillus phoenicis is in progress. Results to date are given

Constraints from TcT_c and the isotope effect for MgB2_2

With the constraint that $T_c = 39$ K, as observed for MgB$_2$, we use the Eliashberg equations to compute possible allowed values of the isotope coefficient, $\beta$. We find that while the observed value $\beta= 0.32$ can be obtained in principle, it is difficult to reconcile a recently calculated spectral function with such a low observed value

Making the State Responsible: Intersex Embodiment, Medical Jurisdiction, and State Responsibility

Through consideration of new developments in the United Kingdom's intersex policy, this article traces the ways in which responsibility is produced, naturalized, and avoided by individuals, institutions, and the state. Jurisdiction is identified as a barrier to the attribution of responsibility that must be overcome to achieve progress in relation to the needs of intersex people. By bringing together jurisdictional analysis and vulnerability theory, this article demonstrates how the state has traditionally abrogated responsibility by compartmentalizing specific practices as governed by medical authority. It highlights that such accounts mask the role of the state in the creation of jurisdiction and the ways in which governance is conducted. Challenging these boundaries allows vulnerability theorists to move the state towards greater levels of responsibility. By combining these theoretical tools, the article enhances the practical utility of vulnerability theory and advances an important agenda for intersex people

The caloron correspondence and higher string classes for loop groups

We review the caloron correspondence between $G$-bundles on $M \times S^1$ and $\Omega G$-bundles on $M$, where $\Omega G$ is the space of smooth loops in the compact Lie group $G$. We use the caloron correspondence to define characteristic classes for $\Omega G$-bundles, called string classes, by transgression of characteristic classes of $G$-bundles. These generalise the string class of Killingback to higher dimensional cohomology.Comment: 21 pages. Author addresses adde
