A pilot study on constructing a Scottish sectoral CO2 emissions account

To calculate polluting emissions, the Scottish economy was divided into 76 sectors and the pollution attributable to each sector was estimated. We used emission/output ratios for the UK, but then further adjusted estimated Scottish emissions, using the ratio of economic activity for each sector between Scotland and the UK

Chemical structure matching using correlation matrix memories

This paper describes the application of the Relaxation By Elimination (RBE) method to matching the 3D structure of molecules in chemical databases within the frame work of binary correlation matrix memories. The paper illustrates that, when combined with distributed representations, the method maps well onto these networks, allowing high performance implementation in parallel systems. It outlines the motivation, the neural architecture, the RBE method and presents some results of matching small molecules against a database of 100,000 models

Incorporation of nitrogen from crop residues into light fraction organic matter in soils with contrasting management histories

The proportion of N from crop residues entering the light-fraction organic matter (LFOM) pool was investigated in soils with contrasting soil organic matter and microbial characteristics arising from different management histories. A laboratory experiment was conducted in which 15N-labelled sugar beet, Brussels sprout or ryegrass shoots, which possessed a range of C/N contents, and hence different biochemical qualities, were incorporated into a sandy–loam soil collected from within a field (FC) or from the field margin (FM). Amounts of C and N incorporated into LFOM were determined after 112 days. The FC and FM soils had organic C contents of 0.9% and 2.5%, respectively. Addition of crop residues increased total LFOM N content and reduced its C/N in FC soil but had no effect on total LFOM N or its C/N in FM soil. Ryegrass incorporation into FC was the only treatment in which there was a net increase in LFOM C. Isotopic analysis indicated that more crop-residue-derived N became incorporated into the LFOM N pool in FM relative to FC soil, with per cent crop residue N incorporated ranging from 25.9% to 35.3% in FC and between 38.9 and 68.5 in FM. Incorporation of crop residues had a positive priming effect on pre-existing LFOM N in FM but not FC soil. We conclude that the characteristics of plant material, together with differences in soil organic matter and microbiology resulting from contrasting management, determined the amount of crop residue C and N incorporated into both HFOM and LFOM

Abelian homotopy Dijkgraaf-Witten theory

We construct a version of Dijkgraaf-Witten theory based on a compact abelian Lie group within the formalism of Turaev's homotopy quantum field theory. As an application we show that the 2+1-dimensional theory based on U(1) classifies lens spaces up to homotopy type.Comment: 23 pages, 1 figur

The Caddoan Ceramics from the Gray\u27s Pasture Site (41HS524), Harrison County, Texas

This paper discusses the Caddoan ceramics recovered during the 1992 Northeast Texas Archeological Society Field School at the Gray\u27s Pasture site (41HS524) on Clark\u27s Creek, a few miles south of Hallsville, Texas and about 2 miles from the Sabine River floodplain. During the course of the excavations, an extensive Caddoan settlement was documented on a series of knolls on a broad terrace landform overlooking the Clark\u27s Creek floodplain, and each of those areas contains Caddoan ceramics. Most notably, a dense concentration of Caddoan ceramics, as well as two burials with whole ceramic vessels, was encountered in the northwestern part of the site, and the majority of the ceramics are from this area. The four site areas include Areal (Unit 1) on a knoll at the northeastern part of the site, Area II on the terrace at the far eastern end of the site (Units 3 and 7), Area lll on the crest of the landform in the central and southwestern part of the site (Units 2, 5, and 6), and Area IV in the northwestern part of the site (Units 8, 8X, 10-16). Unit 4 belongs in Area III, and contained a number of sherds, but these artifacts are missing, except for one plain sherd. Unit 9, in the southeastern part of the site only had a few plain sherds. A total of 2352 sherds and four vessels comprise the Caddoan ceramic assemblage from Gray\u27s Pasture. This includes 1740 plain body and base sherds, 61 plain rims, and 551 decorated rim and body sherds. About 81% of the sherds are from ArealV, with 9.3% of the sherds from Area III. There are 71 decorated rim sherds and 480 decorated body sherds (not including 11 red slipped sherds). The plain/decorated sherd ratio is 3.27 for the site as a whole, and ranges from 3.21 to 3.69 by site area. This is consistent with other pre-A.D. 1200 Caddoan sites in the Red, middle Sabine, and Neches-Angelina river basins, where such sites have plain/decorated sherd ratios that range between 2.97-4.80. Thirteenth and 14th century sites in these areas have plain/decorated sherd ratios of 1.30- 1.61, and Late Caddoan sites dating between ca. A.D. 1450--1650 have ratios of 0.56- 1.03. Through time, more Caddoan vessels are decorated, and vessels are more completely covered with decoration, rather than having the decoration confined primarily to the rim
