Characteristics of Ten Tropical Hardwoods from Certified Forests in Bolivia. Part II. Natural Durability to Decay Fungi

The natural durability of 10 lesser known, commercially available Bolivian hardwoods to decay fungi was evaluated using a modified ASTM soil-block analysis for 12 weeks. The blocks were then retested for an additional 12 weeks to determine their level of decay resistance, as determined by percentage of weight loss. Astronium urundeuva, Caesalpinia cf. pluviosa, Schinopsis quebrachocolorado, and Tabebuia sp. (Iapacho group) were found to be highly resistant to decay; Amburana cearensis, Anadenanthera colubrina (syn: A. macrocarpa), Aspidosperma cylindrocarpon, Diplotropis purpurea, and Guibourtia chodatiana, resistant to decay; and Phyllostylon rhamnoides, moderately resistant to decay. We conclude that an extended soil-bottle test is an effective tool for assessing the level of natural durability of these and other tropical species

Correcting density-driven errors in projection-based embedding

Projection-based embedding provides a simple and numerically robust framework for multiscale wavefunction-in-density-functional-theory (WF-in-DFT) calculations. The approach works well when the approximate DFT is sufficiently accurate to describe the energetics of the low-level subsystem and the coupling between subsystems. It is also necessary that the low-level DFT produces a qualitatively reasonable description of the total density, and in this work, we study model systems where delocalization error prevents this from being the case. We find substantial errors in embedding calculations on open-shell doublet systems in which self-interaction errors cause spurious delocalization of the singly occupied orbital. We propose a solution to this error by evaluating the DFT energy using a more accurate self-consistent density, such as that of Hartree-Fock (HF) theory. These so-called WF-in-(HF-DFT) calculations show excellent convergence towards full-system wavefunction calculations

Chimeric cells of maternal origin do not appear to be pathogenic in the juvenile idiopathic inflammatory myopathies or muscular dystrophy.

INTRODUCTION: Microchimeric cells have been studied for over a decade, with conflicting reports on their presence and role in autoimmune and other inflammatory diseases. To determine whether microchimeric cells were pathogenic or mediating tissue repair in inflammatory myopathies, we phenotyped and quantified microchimeric cells in juvenile idiopathic inflammatory myopathies (JIIM), muscular dystrophy (MD), and noninflammatory control muscle tissues. METHOD: Fluorescence immunophenotyping for infiltrating cells with sequential fluorescence in situ hybridization was performed on muscle biopsies from ten patients with JIIM, nine with MD and ten controls. RESULTS: Microchimeric cells were significantly increased in MD muscle (0.079 ± 0.024 microchimeric cells/mm(2) tissue) compared to controls (0.019 ± 0.007 cells/mm(2) tissue, p = 0.01), but not elevated in JIIM muscle (0.043 ± 0.015 cells/mm(2)). Significantly more CD4+ and CD8+ microchimeric cells were in the muscle of patients with MD compared with controls (mean 0.053 ± 0.020/mm(2) versus 0 ± 0/mm(2) p = 0.003 and 0.043 ± 0.023/mm(2) versus 0 ± 0/mm(2) p = 0.025, respectively). No differences in microchimeric cells between JIIM, MD, and noninflammatory controls were found for CD3+, Class II+, CD25+, CD45RA+, and CD123+ phenotypes, and no microchimeric cells were detected in CD20, CD83, or CD45RO populations. The locations of microchimeric cells were similar in all three conditions, with MD muscle having more microchimeric cells in perimysial regions than controls, and JIIM having fewer microchimeric muscle nuclei than MD. Microchimeric inflammatory cells were found, in most cases, at significantly lower proportions than autologous cells of the same phenotype. CONCLUSIONS: Microchimeric cells are not specific to autoimmune disease, and may not be important in muscle inflammation or tissue repair in JIIM

The Little Paint Site: A Classic Toyah Camp on the South Llano River, Kimble County, Texas

On behalf of the Texas Department of Transportation (TxDOT), SWCA Environmental Consultants (SWCA) conducted testing and data recovery investigations at the Little Paint site (41KM226), a prehistoric multi-component site in the US 377 right-of-way along the South Llano River in Kimble County, Texas. While the site revealed Archaic and Late Prehistoric components, the earlier components were stratigraphically intermixed. Consequently, data recovery focused almost entirely on a discrete Toyah component, which, based on earlier test excavations conducted in August and September 2006, had previously been determined to be eligible for listing on the National Register of Historic Places and as a State Archeological Landmark. SWCA performed the investigations under Texas Antiquities Permits 4184 and 4318. Kevin A. Miller served as Principal Investigator. The excavations recovered approximately 102 m2 of a stratigraphically-discrete Toyah component consisting of rock-lined hearths, Perdiz points, Cliffton points, a bird-bone bead, bone-tempered ceramics, bifaces, scrapers (notably end scrapers on blade-flakes), various informal lithic tools, drills, awls, debitage, and faunal remains. Based on the assemblage, the site is interpreted as a Toyah basecamp as indicated by a diversity of tool forms and site furniture. The component has good integrity, is vertically and horizontally discrete, and contains a substantial amount of archaeological materials. The suite of 16 radiometric dates indicates intermittent Toyah occupations between 240 and 570 years ago, a time range that is generally consistent with recognized span of the Toyah assemblage. The archaeological assemblage and site structure, however, suggests a possible single Toyah occupation. While not a focal point of the data recovery investigations, the excavations also recovered mixed Archaic components below the Toyah component. Artifacts include diagnostic point styles that indicate Late Archaic to early Late Prehistoric occupations, representing 1,000 to 2,000 years of the regional cultural chronology compressed within a thin stratum. Based on the findings, the depositional conditions below the Toyah component, as was previously determined by the testing data, were found to be generally not conducive to the formation of stratigraphic separation of the successive occupations. This compression resulted in intermixing of components and poor integrity. Below the mixed Archaic zone, deeply buried Middle to Early Archaic deposits were identified. These retained a better potential for significant isolable strata, but these deeper deposits were beyond the project impacts and therefore were not the subject of mitigative efforts. The deeper deposits are preserved by avoidance. As previously determined and further substantiated by the data recovery investigations, the Little Paint site, because of the Toyah component and perhaps earlier deposits, is eligible for National Register of Historic Places listing under Criterion D, 36 CFR 60.4, and eligible for State Archeological Landmark designation under Criteria 1 and 2 of the Rules of Practice and Procedure for the Antiquities Code of Texas, 13 TAC 26.8. The excavations have mitigated the adverse effects of the US 377 bridge replacement by recovering the vast majority of the Toyah component within the area of potential effect of the roadway undertaking. No further archaeological work is recommended. Portions of the site outside of the right-of-way have not been fully evaluated. The artifacts and records from the project are curated at the Center for Archaeological Studies, Texas State University
