    This report documents results of detailed geological and geochemical studies in Aiken and Lexington Counties, South Carolina. The studies were undertaken in the spring of 1979 in order to determine the origin, abundance, and areal extent of uraniferous Carolina Coastal Plain. Gorceixite is a hydrated barium aluminum phosphate mineral. The identification fo gorceixite in Aiken County caused much interest because of the 75 to 960 ppM uranium associated with it. Gorceixite is a rare secondary mineral that was first reported as rolled pebbles in diamond sands of Brazil and Africa. Gorceixite has also been found in Dale Colunty, Alabama and Garland County, Arkansas. In Aiken County, South Carolina, gorceixite is found as thin seams or nodules interlayered with sands and mottled clays of the late Eocene (Jackson) Barnwell Group. Electron microprobe analysis of Aiken County gorceixite indicates that the relative abundances of major elements are: Ba>Al>P>Si, Sr>F>Fe>Ca. Also present in amounts greater than 0.05% are K, Ti, Y, La, and U. Ferguson et al. (1979) noted that the uranium in Aiken County gorceixite is in disequilibrium with its decay products, indicating relatively recent enrichment of uranium. Gamma-ray spectrometry measurements, which measure Bi-214, yield estimated concentrations of U/sub 3/O/sub 8/(eU/sub 3/O/sub 8/) of <5 to 20 ppM, whereas chemical analyses show much higher (75 to 960 ppM) concentrations.

    This report documents the archaeological investigation of Site 7 of the proposed Three Rivers Regional Landfill and Technology Center in Aiken County on the United States Department of Energy`s Savannah River Site (SRS) in Aiken and Barnwell Counties, South Carolina. Pedestrian and subsurface survey techniques were used to investigate the 1,403-acre project area. Survey resulted in the discovery of 23 previously unrecorded sites and 11 occurrences; six previously recorded sites were also investigated. These sites consist of six prehistoric sites, nine historic sites, and 14 sites with both prehistoric and historic components. Sites locations and project area boundaries are provided on a facsimile of a USGS 7.5 topographic map. The prehistoric components consist of very small, low-density lithic and ceramic scatters; most contain less than 10 artifacts. Six of the prehistoric components are of unknown cultural affiliation, the remaining prehistoric sites were occupied predominately in the Woodland period. The historic sites are dominated by postbellum/modem home places of tenant and yeoman farmers but four historic sites were locations of antebellum house sites (38AK136, 38AK613, 38AK660, and 38AK674). The historic sites also include an African-American school (38AK677).

    The Lower Savannah River Project was established in 1986 to improve our understanding of the hydrogeologic conditions in west-central South Carolina. Six progress reports have been written since 1987. This report covers the period from July 1, 1994, to June 30, 1995. During the current phase, work focused on locating and procuring suitable sites for future well clusters; drafting well-construction specifications and bid packages; drilling monitoring wells at site C-7; and completing two comprehensive reports. Land was acquired for three future well-cluster sites: C-11, C-13, and C-15. Site C-11 will be located at the Oakwood Fire Tower in Aiken County. This land was made available through the South Carolina Forestry Commission. Land for site C-13 was donated by the Wildlife Division of the South Carolina Department of Natural Resources and will be located at Little Hell Landing on the Savannah River flood plain southwest of Millet in Allendale County. Site C-15 will be located at Gillisonville in northern Jasper County. A 0.9-acre parcel of land was purchased from Westvaco, Inc., for this site. Well specifications and bid packages were drawn up for the construction of seven monitoring wells at site C-10, three at C-13, and two at C-15. Specific-capacity values of nine wells at site C-7 range from 0.3 to 20.6 gpm/ft (gallons per minute per foot of drawdown). Two deep Cretaceous wells were drilled at site C-7, one each in the Midville and Dublin aquifer systems. An upward hydraulic gradient exists between the aquifers. Two comprehensive reports were completed during this phase of the project: (1) a compilation and interpretation of data collected from the project since its inception in 1986, and (2) a detailed description of the hydrogeologic framework of west-central South Carolina and the hydrologic characteristics of the aquifers and confining units.

    The project area for the proposed Central Sanitary Wastewater Treatment Facility on the Savannah River Site includes a six-acre tract along Fourmile Branch and 18 mi of trunk line corridors. Archaeological investigations of the six-acre parcel resulted in the discovery of one small prehistoric site designated 38AK465. This cultural resource does not have the potential to add significantly to archaeological knowledge of human occupation in the region. The Savannah River Archaeological Research Program (SRARP) therefore recommends that 38AK465 is not eligible for nomination to the National Register of Historic Places (NRHP) and further recommends a determination of no effect. Archaeological survey along the trunk line corridors implicated previously recorded sites 38AK92, 38AK145, 38AK415, 38AK417, 38AK419, and 38AK436. Past disturbance from construction had severely disturbed 38AK92 and no archaeological evidence of 38AK145, 38AK419, and 38AK436 was recovered during survey. Lacking further evidence for the existence of these sites, the SRARP recommends that 38AK92, 38AK145, 38AK419, and 38AK436 are not eligible for nomination to the NRHP and thus warrant a determination of no effect. Two of these sites, 38Ak415 and 38AK417, required further investigation to evaluate their archaeological significance. Both of the sites have the potential to yield significant data on the prehistoric period occupation of the Aiken Plateau and the SRARP recommends that they are eligible for nomination to the NRHP. The Savannah River Archaeological Research Program recommends that adverse effects to sites 38AK415 and 38AK417 from proposed construction can be mitigated through avoidance.

    Preliminary paleontologic, lithologic, and geophysical data from four deep coreholes east of the Savannah River Site in Allendale, Barnwell and Aiken Counties in South Carolina indicate the presence of four Upper Cretaceous formations and seven Tertiary formations in a dip-oriented geologic section. Hydrologic and lithologic data have been used to delineate three aquifer systems along the same section. The Cretaceous units are composed mainly of sand and clay with minor amounts of carbonates. The lowermost unit is correlative with the Cape Fear Formation. The upper three Cretaceous units are correlative with the Lumbee Group (Middendorf, Black Creek, Peedee). Updip units of the Tertiary section are mainly sand and clay, becoming increasingly calcareous downdip. The lower two Tertiary units are correlative with the Black Mingo Group (Ellenton, Williamsburg). Two middle units are correlative with the Orangeburg Group (Congaree, Santee) and the upper three units correlate with the Barnwell Group (Clinchfield, Dry Branch, Tobacco Road). Hydrologic and lithologic data are used to delineate three regional aquifer systems at the downdip terminus of the section; two in the Cretaceous and one in the Tertiary. Updip where the Cretaceous clays cease to act as an effective confining unit, the two aquifer systems coalesce resulting in one Cretaceous and one Tertiary aquifer system. Farther updip the Tertiary confining system pinches out and the entire sedimentary sequence acts as a single aquifer system.

    Twelve archaeological sites and four artifact occurrences were located by intensive survey of two tracts of land for the F and H Surface Enhancement Project on the Savannah River Site, Aiken and Barnwell Counties, South Carolina. Fieldwork in the 480-acre project area included surface reconnaissance of 3.6 linear kilometers of transects, 140 shovel tests along 4.2 linear kilometers of transects, an additional 162 shovel tests at sites and occurrences, and the excavation of six l {times} 2 m test units. All but one of the sites contained artifacts of the prehistoric era; the twelfth site consists of the remains of a twentieth-century home place. The historic site and six of the prehistoric sites consist of limited and/or disturbed contexts of archaeological deposits that have little research potential and are therefore considered ineligible for nomination to the National Register of Historic Places (NRHP). The remaining five sites have sufficient content and integrity to yield information important to ongoing investigations into upland site use. These sites (38AK146, 38AK535, 38AK539, 38AK541, and 38AK543) are thus deemed eligible for nomination to the NRHP and the Savannah River Archaeological Research Program (SRARP) recommends that they be preserved through avoidance or data recovery.

    Horn, Scott, and James L. Hanula. 2004. A survey of cavity-nesting bees and wasps in loblolly pine stands of the Savannah River Site, Aiken County, South Carolina. 39(3): 464-469. Abstract: In recent years concern over widespread losses in biodiversity has grown to include a possible decline of many native pollinators, primarily bees. Factors such as habitat fragmentation, agricultural practices, use of pesticides, the introduction of invasive species, or changes in land use may negatively impact these vital organisims. Most reported studies show that human impacts on pollinators are overwhelmingly negative. Reductions in pollinator populations may profoundly impact plant population dynamics and ecosystem function. Little baseline data exists on the diversity and relative abundance of bees and wasps in southern forests. The objective of this study was to develop a simple, effective method of surveying cavity-nesting bees and wasps and to determine species diversity in mature forests of loblolly pine, the most widely planted tree species in the southern United States.

    Mercury is an element of on-going concern for human and aquatic health. Mercury sequestered in upland and wetland soils represents a source that may contribute to mercury contamination in sensitive ecosystems. An improved understanding of mercury cycling in stream ecosystems requires identification and quantification of mercury speciation and transport dynamics in upland and wetland soils within a watershed. This report presents data for soils collected in 2008 from two small watersheds in New York and South Carolina. In New York, 163 samples were taken from multiple depths or soil horizons at 70 separate locations near Fishing Brook, located in Hamilton County. At McTier Creek, in Aiken County, South Carolina, 81 samples from various soil horizons or soil depths were collected from 24 locations. Sample locations within each watershed were selected to characterize soil geochemistry in distinct land-cover compartments. Soils were analyzed for total mercury, selenium, total and carbonate carbon, and 42 other elements. A subset of the samples was also analyzed for methylmercury.

    The Breezy Hill area in Aiken and Edgefield Counties of west-central South Carolina is a rapidly growing region in need of increasing amounts of ground water. From 1995 to 1998, the local water utility increased ground-water withdrawals in the Breezy Hill area from 1.4 to 2.1 million gallons per day to meet water-supply demands. As development continues, future demands forground water will likely put stress on the surface-and ground-water resources of the area. To address this issue, the U.S. Geological Survey, in cooperation with Aiken County, compiled and interpreted geologic and hydrologic data needed to map the ground-water system in the Breezy Hill study area. The Breezy Hill study area consists of four interfluvial areas comprising the regions between Horse and Little Horse Creeks, Little Horse and Hightower Creeks, Hightower Creek and Franklin Branch, and Franklin Branch and Mims Branch. Across the interfluvial areas, the average elevation of the water-level surface ranged from 200 to 480 feet above sea level, and the average saturated thickness of the Floridan-Midville aquifer ranged from less than 20 to 70 feet thick. A water-level aquifer indicates that recharge to the aquifer occurs mainly within the interfluves. Recharge is derived principally from precipitation, although there is some potential for ground-water recharge from underlying crystalline rocks. Ground water discharges along the flanks of the interfluves into the bounding streams where the elevations of the ground water and streams coincide. From April 1999 to November 2000, calculated long-term normal precipitation totaled about 84.0 inches; however, actual recorded precipitation totaled 69.2 inches, representing about a 17.6 percent decrease in precipitation during this period. Published estimates of annual evapotranspiration range from 30 to 35 inches. A U.S. Geological Survey surface-water gaging station located near the center of the study area on Little Horse Creek monitors runoff from a

    The rare Sc mineral thortveitite, (Sc,Y)2Si2O7, occurs as ??m- to mm-sized crystals in fluorite-bearing granitic pegmatites and the host melagabbro within the Crystal Mountain fluorite deposit, Ravalli County, Montana. Thortveitite is found as colorless and clear to smoky and translucent, subhedral to euhedral prisms up to 3 mm in length in the massive fluroite, as mm-sized anhedra to subhedra in diopside and edenite, and as ??m-sized droplet-like crystals in actinolite. Micrometric textures suggest that some thortveitite exsolved from actinolite, which contains between 1.2 and 2.9 wt.% Sc2O3. The source of the Sc is believed to be magmatic. The physical, optical and crystallographic properties of thortveitite are described. -from Authors

    The South Carolina Department of Natural Resources, Water Resources Division (SCWRD), in collaboration with the United States Department of Energy (USDOE) is conducting a hydrogeologic investigation of the ground-water system(s) peripheral to the Savannah River Site. The study area is located in the Southeastern Coastal Plain hydrogeologic province in Aiken, Allendale and Barnwell Counties, South Carolina. Ground-water movement, quality, and availability are being evaluated in order to better protect and manage this valuable regional resource. The investigation involves a well-cluster system comparable to the one constructed on the SRS. Cluster sites are situated outside the SRS on the basis of study objectives, proximity to the plant`s borders, land availability, and for the optimization of hydrogeologic control. One to three wells are completed into each major aquifer, and at each cluster site, at least one borehole is continuously cored and geophysically logged from land surface to at least 10 feet into unweathered bedrock. Data collected from the ongoing study include 146 paleontologic and palynologic age dates, 100 x-ray diffraction analyses of clay and bulk mineralogy, 442 sieve analyses, 6,040 feet of detailed core description, mineral composition and porosity determined from thin-section analyses, and continuous water-level data. This report is a compilation and interpretation of the {open_quotes}C-well{close_quotes} data that have been generated from the project and that will be used to model and characterize the aquifers and confining units in the region.

    Sources of fecal coliform pollution in a small South Carolina (USA) watershed were identified using inexpensive methods and commonly available equipment. Samples from the upper reaches of the watershed were analyzed with 3M(™) Petrifilm(™) count plates. We were able to narrow down the study's focus to one particular tributary, Sand River, that was the major contributor of the coliform pollution (both fecal and total) to a downstream reservoir that is heavily used for recreation purposes. Concentrations of total coliforms ranged from 2,400 to 120,333 cfu/100 mL, with sharp increases in coliform counts observed in samples taken after rain events. Positive correlations between turbidity and fecal coliform counts suggested a relationship between fecal pollution and stormwater runoff. Antibiotic resistance analysis (ARA) compared antibiotic resistance profiles of fecal coliform isolates from the stream to those of a watershed-specific fecal source library (equine, waterfowl, canines, and untreated sewage). Known fecal source isolates and unknown isolates from the stream were exposed to six antibiotics at three concentrations each. Discriminant analysis grouped known isolates with an overall average rate of correct classification (ARCC) of 84.3 %. A total of 401 isolates from the first stream location were classified as equine (45.9 %), sewage (39.4 %), waterfowl (6.2 %), and feline (8.5 %). A similar pattern was observed at the second sampling location, with 42.6 % equine, 45.2 % sewage, 2.8 % waterfowl, 0.6 % canine, and 8.8 % feline. While there were slight weather-dependent differences, the vast majority of the coliform pollution in this stream appeared to be from two sources, equine and sewage. This information will contribute to better land use decisions and further justify implementation of low-impact development practices within this urban watershed. PMID:25139239

    Constructed between November 1950 and March 1955, the Savannah River Site (SRS) nuclear production facility was a product of the Cold War and its accompanying arms race. The first Soviet atomic detonation in 1949 shook the foundations of American Cold War diplomacy. Although the diplomatic situation with the Soviets had never been amicable since the end of World War 2, the atomic bomb had provided a psychological edge for American policy makers. Worried about the military balance of power in the aftermath of the unanticipated Soviet test, President Harry S. Truman authorized research for construction of a hydrogen or fusion weapon. The program required a new nuclear weapons facility to produce the hydrogen isotope tritium in sufficient quantities to create a large stockpile of fusion weapons.

    2005-09-21

    The United States Department of Energy’s Savannah River Site (SRS) in Aiken, Allendale, and Barnwell Counties, South Carolina, contains an abundance of freshwater wetlands and impoundments. Four large impoundments, as well as several small, abandoned farm and mill ponds, and about 400 Carolina bays and other small, isolated depression wetland ponds are located within the 893 km2 area of the SRS. Crustaceans of the orders Branchiopoda and Copepoda are nearly ubiquitous in these water bodies. Although small in size, these organisms are often very abundant. They consequently play an important trophic role in freshwater food webs supporting fish, larval salamanders, larval insects, and numerous other animals, aquatic and terrestrial. This report provides an introduction to the free-living microcrustaceans of lentic water bodies on the SRS and a comprehensive list of species known to occur there. Occurrence patterns are summarized from three extensive survey studies, supplemented with other published and unpublished records. In lieu of a key, we provide a guide to taxonomic resources and notes on undescribed species. Taxa covered include the orders Cladocera, Anostraca, Laevicaudata, and Spinicaudata of the Subclass Branchiopoda and the Superorders Calanoida and Cyclopoida of Subclass Copepoda. Microcrustaceans of the Superorder Harpacticoida of the Subclass Copepoda and Subclass Ostracoda are also often present in lentic water bodies. They are excluded from this report because they have not received much study at the species level on the SRS.

    1992-08-01

    I measured field metabolic rates (FMR), water fluxes, and activity patterns of the box turtle Terrapene carolina on the Savannah River Plant, Aiken Co., SC, from September, 1987 to October, 1988. Doubly labeled water (HT[sup 18]O) measurements of production (field metabolic rates, FMR) of telemetered turtles were taken in conjunction with measurements of operative temperatures (T[sub e]), turtle movement patterns, and micrometerological data consisting of air, litter, and substrate temperatures, solar and total radiation, and wind speed. Operative temperatures were used to predict standard (SMR) and maximum (MMR) metabolic rates, and these were compared to field metabolic rates (FMR) of box turtles in South Carolina. Turtles were inactive for most of the winter and for long periods of time during the rest of the year. Water fluxes (ml/ kg*D) were 8.8, 18.9, and 26.4 in the winter, late spring, and early fall, respectively. There was no statistically significant sexual difference in FMR so these results were pooled for each season. Mean mass specific metabolic rates (ml CO[sub 2]/g*h) were 0.028, 0.0654, and 0.124 for the winter, spring, and fall, respectively. There was a significant difference in metabolic rates for the seasons of the year. In winter, FMR is substantially elevated above SMR and close to MMR, while in spring and fall FMRs are midway between SMR and MMR (SMR = 0.004, 0.010, and 0.017, and MMR = 0.034, 0.154, and 0.208 (ml CO[sub 2]/9*h) in the winter, spring, and fall, respectively). The low field metabolic rate of box turtles and low annual reproductive output is characteristic of a low energy specialist. This strategy may allow them to survive and flourish in an uncertain resource and reproductive environment by minimizing costs and risks, thereby maintaining greater lifetime reproductive output.

    The 55-acre Golden Strip Septic Tank (GSST) site is an inactive waste hauling and disposal facility in Simpsonville, Greenville County, South Carolina. Land use in the area is predominantly residential. From 1960 to 1975, GSST used the site to dispose of industrial and septic wastes in five unlined lagoons. In 1975, GSST applied for an industrial solid waste permit to dispose of liquid wastes, but the State denied the permit because the proposed disposal method was unacceptable. The State continued its monitoring after the lagoons were filled and graded in 1978, and the results of the monitoring led to additional investigations by EPA in 1984 and 1986 and an RI and supplemental RI from 1989 to 1990 and 1990 to 1991, respectively. EPA identified metal contamination in lagoon soil and sludge, and limited contamination of ground water on the east side of the site. The Record of Decision (ROD) addresses remediation of contaminated soil, as well as sludge and surface water from the lagoons, as a final remedy. Ground water contamination is expected to naturally attenuate within 2 to 5 years after source remediation occurs. The primary contaminants of concern affecting the soil, sludge, and surface water are VOCs including benzene, PCE, toluene, and xylenes; other organics; and metals including arsenic, chromium, and lead.

    Detailed geologic mapping has shown the distribution and lithologic character of stratigraphic units and sedimentary deposits in Williston quadrangle. A middle Eocene stratigraphic unit correlative with the restricted McBean Formation is the oldest unit at the surface. The McBean-equivalent unit occurs at low elevations along drainages in the north of the quadrangle but does not crop out. These beds are typically very fine- to fine-grained quartz sand, locally with abundant black organic matter and less commonly with calcium carbonate. The uppermost middle Eocene Orangeburg District bed, commonly composed of loose, clay-poor, very fine- to fine-grained quartz sand, occurs at the surface in the north and southwest of the quadrangle with sparse exposure. The upper Eocene Dry Branch Formation occurs on valley slopes throughout the quadrangle. The Dry Branch is composed of medium- to very coarse-grained quartz sand with varying amounts on interstitial clay and lesser bedded clay. The upper Eocene Tobacco road Sand occurs on upper valley slopes and some interfluves and consists of very fine-grained quartz sand to quartz granules. The upper Middle Miocene to lower Upper Miocene upland unit caps the interfluves and is dominantly coarse-grained quartz sand to quartz granules, with included granule-size particles of white clay that are weathered feldspars. Loose, incohesive quartzose sands of the eolian Pinehurst Formation, Upper Miocene to Lower Pliocene, occur on the eastern slopes of some interfluves in the north of the quadrangle. Quartz sand with varying included humic matter occurs in Carolina bays, and loose deposits of windblown sand occur on the rims of several Carolina bays. Quaternary alluvium fills the valley floors.

    Martin, D

    2006-10-04

    This taxonomic key was devised to support development of a Rapid Bioassessment Protocol using ants at the Savannah River Site. The emphasis is on ''rapid'' and, because the available keys contained a large number of genera not known to occur at the Savannah River Site, we found that the available keys were unwieldy. Because these keys contained more genera than we would likely encounter and because this larger number of genera required both more couplets in the key and often required examination of characters that are difficult to assess without higher magnifications (60X or higher) more time was required to process samples. In developing this set of keys I recognize that the character sets used may lead to some errors but I believe that the error rate will be small and, for the purpose of rapid bioassessment, this error rate will be acceptable provided that overall sample sizes are adequate. Oliver and Beattie (1996a, 1996b) found that for rapid assessment of biodiversity the same results were found when identifications were done to morphospecies by people with minimal expertise as when the same data sets were identified by subject matter experts. Basset et al. (2004) concluded that it was not as important to correctly identify all species as it was to be sure that the study included as many functional groups as possible. If your study requires high levels of accuracy, it is highly recommended that when you key out a specimen and have any doubts concerning the identification, you should refer to keys in Bolton (1994) or to the other keys used to develop this area specific taxonomic key.

    2000-02-11

    A regional groundwater flow model encompassing approximately 100 mi2 surrounding the C, K, L, and P reactor areas has been developed. The reactor flow model is designed to meet the planning objectives outlined in the General Groundwater Strategy for Reactor Area Projects by providing a common framework for analyzing groundwater flow, contaminant migration and remedial alternatives within the Reactor Projects team of the Environmental Restoration Department. The model provides a quantitative understanding of groundwater flow on a regional scale within the near surface aquifers and deeper semi-confined to confined aquifers. The model incorporates historical and current field characterization data up through Spring 1999. Model preprocessing is automated so that future updates and modifications can be performed quickly and efficiently. The CKLP regional reactor model can be used to guide characterization, perform scoping analyses of contaminant transport, and serve as a common base for subsequent finer-scale transport and remedial/feasibility models for each reactor area.

    2007-06-07

    A graded approach to flow and transport modeling has been used as a cost effective solution to evaluating potential groundwater risk in support of Deactivation and Decommissioning activities at the United States Department of Energy's Savannah River Site. This approach incorporates both simple spreadsheet calculations and complex numerical modeling to evaluate the threat to human health posed by contaminants leaching from decommissioned concrete building slabs. Simple spread sheet calculations were used to produce generic slab concentration limits for a suite of radiological and non-radiological contaminants for a chemical separations area at Savannah River Site. These limits, which are based upon the United States Environmental Protection Agency Soil Screening guidance, were used to eliminate most building slabs from further risk assessment. Of the more than 58 facilities located in the area, to date only one slab has been found to have a contaminant concentration in excess of the area specific slab limit. For this slab, a more rigorous numerical modeling effort was undertaken reducing the conservatisms inherent in the spreadsheet calculations. Using the more sophisticated numerical model, it was possible to show that the remaining contaminant of concern would not likely impact groundwater above drinking water standards.

    The new phosphide ScNiP can be synthesized by arc-melting of ScP and Ni, or by arc-melting of Sc with NiP. The lattice constants, as obtained from the bulk sample, are a = 6.3343(8) {angstrom}, b = 3.7375(7) {angstrom}, c = 7.0917(8), and V = 167.89(4) {angstrom}{sup 3}. ScNiP crystallizes in the Co{sub 2}Si structure type. Although one might assign the trivalent state to Sc, corresponding to a formal ionic formula of Sc{sup 3+}Ni{sup {+-}0}P{sup 3{minus}}, the structure of ScNiP contains Sc-Sc bonds and shows weak metallic properties, as expected based on extended Hueckel calculations.

    The purpose of this monograph is twofold: first, to example historical trends and settlement patterning through time within the boundaries of the present-day Savannah River Site (SRS), and second, to establish a framework for future investigations of historic period occupation in the study area. Settlement patterns are defined as the distribution of archaeological sites across a landscape. Settlement patterning is a response to widely held cultural needs; therefore, it offers a strategic starting point for the functional interpretation of archaeological cultures. The analysis of settlement patterns if useful because it is practical, it shows the spatial dimension of the man-environment interrelationship that is relative to the technological level of the settlement's inhabitants, and it can yield concrete clues regarding social organization.

    A pilot-scale field demonstration of waste isolation using viscous- liquid containment barriers has been planned for the 281-3H retention basin at the Savannah River Site, Aiken, SC. The 281-3H basin is a shallow retention/seepage basin contaminated mainly by radionuclides. The viscous-liquid containment barrier utilizes the permeation of liquid grout to either entomb the contaminants within a monolithic grout structure or to isolate the waste by drastically reducing the permeability, of the soils around the plume. A clear understanding of the hydrogeologic setting of the retention basin is necessary for proper design of the viscous liquid barrier. To aid in the understanding of the hydrogeology of the 281-3H retention basin, and to obtain critical parameters necessary for grout injection design, a series of tests were undertaken in a region immediately adjacent to the basin. The objectives of the LWIT were: 1. To evaluate the general performance of the Lance Injection Technique for grout emplacement at the site, including the range and upper limits of injection pressures, the flow rates applicable for site conditions, as well as the mechanical forces needed for lance penetration. 2. To obtain detailed information on the injectability of the soils immediately adjacent to the H-area retention basin. 3. To identify any high permeability zones suitable for injection and evaluate their spatial distribution. 4. To perform ground penetrating radar (GPR) to gain information on the structure of the soil column and to compare the results with LWIT data. This report will focus on results pertinent to these objectives.

    Photoionization cross sections are calculated for the ground ([Mg] 3p^63d4s^2 ^2D^e) state of atomic Sc for photon energies from threshold to 40.0 eV. The discrete Sc^+ orbitals are generated using both the AUTOSTRUCTURE and CIV3 codes, and R-matrix is used to carry out the cross section calculations. The results are compared with each other, then with previous calculations and available experimental data for final-ionic states representing the 3d and 4s main lines and associated satellites (ionization with excitation) in the region of the 3p -> 3d giant resonances [1]. Reasonably good agreement between our non-relativistic results and experiment is obtained. This work is supported by US DOE and NSF [4pt] [1] S. B. Whitfield, K. Kehoe, R. Wehlitz, M. O.

    This report summarizes the results of the seismic and tornado evaluation of Building 221-H and Penthouse Additions 221-SH, TH, and UH at the Savannah River Plant, Aiken, South Carolina. The main objective of this project was to determine whether Building 221-H and the two-story penthouse addition over Sections 2 through 6 meet the established acceptance criteria for the criterion seismic and tornado loadings. The analyses and evaluations of three related structures -- the exhaust stack 291-H, sand filters 294-H/294-lH, and the connecting air tunnel -- are presented in a separate report. During the progress of the project, both the scope of work and the acceptance criteria for the seismic analyses of Building 221-H went through several revisions since the original criteria were established. As a result, linear elastic, quasi-nonlinear, and nonlinear dynamic analyses were performed to assess the building. The seismic criteria was based on the design response spectrum developed by Dr. George W. Housner with a Design Basis Earthquake ground acceleration of 0.2g and an Operating Basis Earthquake ground acceleration of 0.1g. Chapter 1 discusses the seismic analysis history of this project and the various analysis phases performed. The tornado analysis was performed for a Design Basis Tornado. The analyses considered the effects of wind velocity pressure, atmospheric pressure drop, and missile impact for structural response effects. The evaluation for wind velocity pressure and atmospheric pressure drop effects included consideration of both local and overall structural adequacy. The evaluation of missile impact effects included consideration of overall structural and individual panel response.

  6. Transient electromagnetic imaging of a basin margin underneath the Savannah River Plant, Aiken, South Carolina

    An experimental transient electromagnetic (TEM) survey was performed at the Savannah River Plant (SRP) near Aiken, South Carolina, to assess the viability of a subsurface imaging method. The goal of the survey was improve resolution of mapping the margin of a buried Triassic basin partially underlying SRP. A high data density survey was conducted utilizing multiple large loop transmitters with overlapping profiles of measurements from each transmitter. Any attempt to image subsurface structure requires such data density. A gap in interpretation tolls exists in all electrical methods between layered earth inversion and numerical modeling of two-dimensional (2D) or three-dimensional (3D) structures. Recent TEM research has focused on development of methods to image subsurface geoelectric structure without resorting to numerical modeling. The method described here constructs a subsurface geoelectric image by a novel means of stacking TEM data in both time and space. The stacking procedure is based on knowledge of where currents are flowing in the subsurface of an approximate background model. Weights for stacking of the TEM data into estimates of anomalous current flow on a subsurface grid are calculated from these known current flow patterns as a function of time, measurement position and subsurface grid element position using Biot-Savart's Law. Thus for the SRP survey, a 2D structure is imaged built on knowledge of the fields of an approximate one-dimensional (1D) model. The basin margin under SRP is successfully resolved by the imaging method. The imaging result provides better resolution than obtained by splicing together layered earth inversion models. Various pros and cons of this imaging method are discussed to indicate future directions for TEM imaging. 10 refs., 6 figs.

    In the controlled synthesis of ScOOH nanomaterials, the surfactant molecule Na3 Cit not only helps to manipulate the crystallographic structures, but also to initiate the transfer from α-ScOOH to γ-ScOOH. Further annealing of ScOOH generates cubic Sc2 O3 with morphologies inherited from respective origins. When doped with lanthanide ions, both ScOOH and Sc2 O3 can be utilized for high-temperature probing and light-emitting-diode lighting. PMID:27184777

  11. ESS SC Linac Design Overview

    2002-12-01

    The ESS project (European Spallation Source) aims to produce high power beams for condensed matter studies. One option consists in having both H+ and H- beams. They have to be accelerated and guided to the different spallation targets. Beam power up to 5 MW at 50 Hz plus 5 MW at 16.2/3 Hz, will be delivered on respectively the Short Pulse Target Station and the Long Pulse Target Station. Two 50 mA H- branches are funnelled with one 100 mA H+ beam at around 20 MeV. A chopper line between two RFQs and DTLs constitutes the H- front end. The H+ front end is composed of one RFQ and one DTL. After the funnel, the two species are transported through the same linac up to 1.334 GeV. This common part is composed of a SDTL and a CCL from 20 to 185 MeV and followed by a SuperConducting Linac (SCL) to reach the final energy. Up to recently (ESS Volume III 1996), a NC version of the linac had been extensively studied and constituted the reference option. However, given the fantastic progresses made on SC technology and the many potential advantages, a SC alternative was developed. We concentrate on this option.

    Patients with Hb SC disease were found to have microcytic and hyperchromic red cell indices despite mild reticulocytosis. Iron deficiency anemia was ruled out by the finding of normal serum ferritin levels. In order to determine whether the microcytosis was due to coexistent alpha-thalassemia, restriction endonuclease mapping was performed on genomic DNA extracted from peripheral blood leukocytes. Patients with Hb SC disease had microcytic indices despite the presence of a full complement of four alpha-genes (alpha alpha/alpha alpha), suggesting that the microcytosis may be due to cellular dehydration (or xerocytosis), since the mean corpuscular hemoglobin concentration in Hb SC disease patients was significantly higher than in controls. This possibility was investigated further by the determination of RBC cation content. RBC Na levels were similar in SC and normal red cells. Hb SC RBCs, however, had significantly reduced K levels. These findings show that RBC cation content, and thus cell water, is decreased in Hb SC disease. The decreased RBC K level in the presence of normal cellular Na concentration suggests selective K loss that is not due to inhibition of the Na K pump. Ouabain-insensitive K+ efflux was increased to four times normal in SC cells. Cell dehydration was confirmed by the demonstration of increased high-density RBCs on discontinuous Stractan density gradients and by osmotic gradient ektacytometry. Cellular dehydration and its sequelae were worse in CC erythrocytes and milder in AC cells than in Hb SC red cells. Taken together, these data indicate that in Hb SC disease the RBCs are severely dehydrated and typically microcytic and hyperchromic. Hb SC RBCs seem to be dehydrated due to selective K loss. These findings suggest a functional interrelationship between Hb SC, the red cell membrane, and cation regulation. PMID:2947642

    The complete set of elastic constants for Sc and ScD[sub 0.18] has been measured at room temperature. The results show that the addition of hydrogen to this rare-earth metal has a qualitatively different effect than the addition of hydrogen to transition metals such as palladium, vanadium, niobium, and tantalum. In the case of Sc all five elastic constants increase with the addition of hydrogen. The bulk modulus for ScD[sub 0.18] is 9.5% higher than that for Sc. The Debye temperature computed from the room-temperature elastic constants is 355 K for Sc and 371 K for ScD[sub 0.18].

    Schneider, William; Kneisel, Peter; Rode, Claus

    2003-05-01

    The proposed rare isotope accelerator (RIA) design consists of a normally conducting radio frequency quadruple (RFQ) section, a superconducting (SC) drift tube cavity section, a SC elliptical multi-cell cavity section and two charge strippers with associated charge state selection and beam matching optics. The SC elliptical section uses two or three multi-cell beta cavity types installed into cryomodules to span the energy region of about 84.5 MeV/nucleon up to 400 MeV/nucleon. This paper focuses on the gradient optimization of these SC elliptical cavities that provide a significant portion of the total acceleration to the beam. The choice of gradient coupled with the cavity quality factor has a strong affect on the overall cost of the accelerator. The paper describes the optimization of the capital and operating cost associated with the RIA elliptical cavity cryomodules.

    An exceptionally stable hollow cage containing 20 scandium atoms and 60 carbon atoms has been identified. This Sc20C60 molecular cluster has a Th point group symmetry and a volleyball-like shape that we refer to below as ``Volleyballene''. Electronic structure analysis shows that the formation of delocalized π bonds between Sc atoms and the neighboring pentagonal rings made of carbon atoms is crucial for stabilizing the cage structure. A relatively large HOMO-LUMO gap (~1.4 eV) was found. The results of vibrational frequency analysis and molecular dynamics simulations both demonstrate that this Volleyballene molecule is exceptionally stable.An exceptionally stable hollow cage containing 20 scandium atoms and 60 carbon atoms has been identified.

    2016-05-01

    K2SC (K2 Systematics Correction) models instrumental systematics and astrophysical variability in light curves from the K2 mission. It enables the user to remove both position-dependent systematics and time-dependent variability (e.g., for transit searches) or to remove systematics while preserving variability (for variability studies). K2SC automatically computes estimates of the period, amplitude and evolution timescale of the variability for periodic variables and can be run on ASCII and FITS light curve files. Written in Python, this pipeline requires NumPy, SciPy, MPI4Py, Astropy (ascl:1304.002), and George (ascl:1511.015).

  3. ZETA Potential Induced Particle Generation in SC2 Cleaning

    2002-12-01

    After etch and photo resist (PR) strip, particle and byproduct removal treatment is inevitable. SC1/SC2 cleaning process is one of the useful wet cleaning processes to remove them. In most cases, the equipment is batch type (25 or 50 wafers dip into bath) in which particles lifted from edge or backside of wafer move into chip easily by the stream of chemical. Especially in the process of film like Si3N4 with high dielectric constant, the particle issue is more serious. Following SC1 cleaning (main chemical is NH4OH), SC2 cleaning (main chemical is HCl) causes particles to be attached to wafer. The lifted particles in SC1 cleaning are attached to wafer strongly by ZETA potential, which is enhanced when the PH of chemical is lower than 4 (PH of SC2 chemical is about 1.3). SC2 cleaning after SC1 cleaning is not desirable process sequence. But, SC2 chemical is useful for removing metal contamination generated in etch equipment during the etch process. Skipping SC2 cleaning is desirable in the process which metal contamination has no impact on. But, if you want to use SC2 cleaning or other acid chemical (PH below 4) for a guarantee of quality of device, it should be processed before SC1 cleaning.

    Al-Sc and Al-Sc-Zr alloys containing 0.05, 0.1 and 0.5 wt.% Sc and 0.15 wt.% Zr were investigated using optical microscopy, electron microscopy and X-ray diffraction. The phase composition of the alloys and the morphology of precipitates that developed during solidification in the sand casting process and subsequent thermal treatment of the samples were studied. XRD analysis shows that the weight percentage of the Al{sub 3}Sc/Al{sub 3}(Sc, Zr) precipitates was significantly below 1% in all alloys except for the virgin Al0.5Sc0.15Zr alloy. In this alloy the precipitates were observed as primary dendritic particles. In the binary Al-Sc alloys, ageing at 470 deg. C for 24 h produced precipitates associated with dislocation networks, whereas the precipitates in the annealed Al-Sc-Zr alloys were free of interfacial dislocations except at the lowest content of Sc. Development of large incoherent precipitates during precipitation heat treatment reduced hardness of all the alloys studied. Growth of the Al{sub 3}Sc/Al{sub 3}(Sc, Zr) precipitates after heat treatment was less at low Sc content and in the presence of Zr. Increase in hardness was observed after heat treatment at 300 deg. C in all alloys. There is a small difference in hardness between binary and ternary alloys slow cooled after sand casting.

  6. Initial Assessment of Stewards of Children Program Effects on Child Sexual Abuse Reporting Rates in Selected South Carolina Counties.

    2016-02-01

    Child sexual abuse (CSA) prevention programs often include a focus on increased reporting of suspected abuse, in addition to other prevention components such as helping trainees recognize suspected abusive situations. This study aimed to determine whether the Stewards of Children prevention program is associated with increased CSA reporting. Analyses examined whether rates of CSA allegations increased over time in three counties in South Carolina (SC) targeted with program dissemination efforts and whether CSA reporting trends differed between the three targeted counties and three comparison counties that did not experience substantial program dissemination. CSA allegation data were obtained by county and year for predissemination and postdissemination periods from the SC Department of Social Services. Results indicated that, for the targeted counties but not the nontargeted counties, estimated allegation rates increased significantly over time, corresponding with the onset of significant program dissemination efforts. Results also indicated significant between-groups differences in allegation trends for targeted versus nontargeted counties. These findings suggest that the Stewards prevention intervention may be associated with increased CSA allegations. However, results require replication with randomization of counties. Moreover, whether increased reporting is associated with decreased CSA incidence remains unknown. PMID:26530898

    By introducing CO2 as the oxygen source during the arcing process, a new isomer of Sc2O@C82, Sc2O@C(3v)(8)-C82, previously investigated only by computational studies, was discovered and characterized by mass spectrometry, UV-vis-NIR absorption spectroscopy, cyclic voltammetry, (45)Sc NMR, density functional theory (DFT) calculations, and single-crystal X-ray diffraction. The crystallographic analysis unambiguously elucidated that the cage symmetry was assigned to C(3v)(8) and suggests that Sc2O cluster is disordered inside the cage. The comparative studies of crystallographic data further reveal that the Sc1-O-Sc2 angle is in the range of 131.0-148.9°, much larger than that of the Sc2S@C(3v)(8)-C82, demonstrating a significant flexibility of dimetallic clusters inside the cages. The electrochemical studies show that the electrochemical gap of Sc2O@C(3v)(8)-C82 is 1.71 eV, the largest among those of the oxide cluster fullerenes (OCFs) reported so far, well correlated with its rich abundance in the reaction mixture of OCF synthesis. Moreover, the comparative electrochemical studies suggest that both the dimetallic clusters and the cage structures have major influences on the electronic structures of the cluster fullerenes. Computational studies show that the cluster can rotate and change the Sc-O-Sc angle easily at rather low temperature. PMID:26840749

    Excited states of neutron-rich odd-A and odd-odd Sc isotopes, populated in deep inelastic multinucleon transfer reactions, induced by a {sup 238}U beam on a thin {sup 48}Ca target, have been identified. A strong feeding of both yrast and nonyrast states in such a reaction is illustrated using a combination of a large efficiency spectrometer and a {gamma} detector array. The structure of the populated states is interpreted in terms of the role of the valence proton and neutrons and compared to shell model calculations in the full pf shell.

    DMPA-SC 104 mg/0.65 mL is a new, low-dose subcutaneous (SC) formulation of Depo-Provera contraceptive injection (150 mg/mL medroxyprogesterone acetate injectable suspension) that provides efficacy, safety and immediacy of onset equivalent to Depo-Provera intramuscular (IM) injection. Two large, open-label, Phase 3 studies assessed the 1-year contraceptive efficacy, safety and patient satisfaction with DMPA-SC administered every 3 months (12-13 weeks). Zero pregnancies were reported in both studies, which included a total of 16,023 woman-cycles of exposure to DMPA-SC and substantial numbers of overweight or obese women. DMPA-SC was well-tolerated and adverse events were similar to those reported previously with Depo-Provera IM. Thus, DMPA-SC offers women a new, highly effective and convenient long-acting contraceptive option. PMID:15451329

    Loral Aeronutronic is supporting the IHAVS project by integrating Navy-furnished NITE Hawk Targeting FLIR Pod (AN/AAS-38B) Weapons Replaceable Assemblies (WRAs) with Loral-furnished aft section and interface module WRAs for flight testing on a TAV-8B. Loral developed an aft section WRA without the conformal fairing required for installation on an F/A-18 and incorporated a self-cooling system. WRAs from the AN/AAS-38B pod are integrated in this aft section to provide a pod which is functionally the same as the F/A-18 system yet can be installed on any aircraft. Loral calls this derivative of the F/A-18 NITE Hawk pod the NITE Hawk Self-Cooled (SC) pod. The NITE Hawk SC has also has also been flight demonstrated on the F-15, F-16 and F-14 platforms and is the baseline laser targeting system on the Spanish Air Force's EF-2000 aircraft. The Loral-developed interface module WRA provides the capability to translate messages from any aircraft mission computer into the particular format design for the F/A-18 controller processor WRA. This maintains maximum commonality to the AN/AAS-38B WRAs. The interface module provides for signal processing of the FLIR video and includes the capability to electronically zoom, freeze, and format the video output into any standard required by the aircraft.

    A three-week cruise to obtain high-resolution boomer and multichannel seismic-reflection profiles supported two project activities of the USGS Coastal and Marine Geology (CMG) Program: (1) evaluating the earthquake and related geologic hazards posed by faults in the near offshore area of southern California and (2) determining the pathways through which sea-water is intruding into aquifers of Los Angeles County in the area of the Long Beach and Los Angeles harbors. The 2000 cruise, A1-00-SC, is the third major data-collection effort in support of the first objective (Normark et al., 1999a, b); one more cruise is planned for 2002. This report deals primarily with the shipboard operations related to the earthquake-hazard activity. The sea-water intrusion survey is confined to shallow water and the techniques used are somewhat different from that of the hazards survey (see Edwards et al., in preparation).

    A detailed study on the electronic structure and Fermi surface (FS) of superconducting Heusler compounds ScAu{sub 2}(Al, In) and ScPd{sub 2}(Sn, Pb) has been carried out using first principles electronic structure calculations. The spin orbit coupling is found to play a major role in understanding the band structure and FS. Analysis of the data shows the importance of spin orbit coupling effect in the above compounds. The bands which cross Fermi level (EF) are found to be dominated by the Sc d{sub t2g}-states. The calculated total density of states are in good agreement with the experimentally reported value for ScPd{sub 2}Sn. Under compression we find a change in the Fermi surface topology of ScPd{sub 2}Sn at V/V{sub 0} = 0.95 (pressure of≈15 GPa), which is explained using the band structure calculations.

    Rapid industrial and urban growth is anticipated in the vicinity of Crowders Creek near Clover, S.C., and Steele Creek near Fort Mill, S.C. These subbasins are in the Catawba River Basin in York County, S.C. To obtain baseline information on these basins prior to urbanization, gaging stations 02145642 (Crowders Creek near Clover, S.C.) and 021467801 (Steele Creek near Fort Mill, S.C.) were established to collect streamflow and water-quality data. Continuous stream-stage and streamflow data were collected during the periods of March 23, 1991 to September 30, 1992, and May 29, 1991 to September 30, 1992, for stations 02145642 and 021467801, respectively. Average streamflows for stations 02145642 and 021467801 for the study period were 80.5 cubic feet per second and 28.6 cubic feet per second, respectively. Water-quality data were collected on four separate occasions at each gage site; two samplings during low-flow events and two samplings during high-flow events. Fecal coliform concentrations exceeded minimum standards for freshwater with other physical and chemical constituents meeting South Carolina Department of Health and Environmental Control standards.

    Although hemoglobin SC (HbSC) disease is usually considered less severe than sickle cell anemia (SCA), which includes HbSS and HbS/β(0) -thalassemia genotypes, many patients with HbSC experience severe disease complications, including vaso-occlusive pain, acute chest syndrome, avascular necrosis, retinopathy, and poor quality of life. Fully 20 years after the clinical and laboratory efficacy of hydroxyurea was proven in adult SCA patients, the safety and utility of hydroxyurea treatment for HbSC patients remain unclear. Recent NHLBI evidence-based guidelines highlight this as a critical knowledge gap, noting HbSC accounts for ∼30% of sickle cell patients within the United States. To date, only 5 publications have reported short-term, incomplete, or conflicting laboratory and clinical outcomes of hydroxyurea treatment in a total of 71 adults and children with HbSC. We now report on a cohort of 133 adult and pediatric HbSC patients who received hydroxyurea, typically for recurrent vaso-occlusive pain. Hydroxyurea treatment was associated with a stable hemoglobin concentration; increased fetal hemoglobin (HbF) and mean corpuscular volume (MCV); and reduced white blood cell count (WBC), absolute neutrophil count (ANC), and absolute reticulocyte count (ARC). Reversible cytopenias occurred in 22% of patients, primarily neutropenia and thrombocytopenia. Painful events were reduced with hydroxyurea, more in patients >15 years old. These multicenter data support the safety and potentially salutary effects of hydroxyurea treatment for HbSC disease; however, a multicenter, placebo-controlled, Phase 3 clinical trial is needed to determine if hydroxyurea therapy has efficacy for patients with HbSC disease.

  12. Design of SC walls and slabs for impulsive loading

    Varma, Amit H.

    2015-11-11

    Reinforced concrete (RC) structures have historically been the preferred choice for blast resistant structures because of their mass and the ductility provided by steel reinforcement. Steel-plate composite (SC) walls are a viable alternative to RC for protecting the infrastructure against explosive threats. SC structures consist of two steel faceplates with a plain concrete core between them. The steel faceplates are anchored to the concrete using stud anchors and connected to each other using tie bars. SC structures provide mass from the concrete infill and ductility from the continuous external steel faceplates. This dissertation presents findings and recommendations from experimental and analytical investigations of the performance of SC walls subjected to far-field blast loads.

    The 1.42- to 2.40-micrometer spectrum of Kuiper belt object 1993SC was measured at the Keck Observatory in October 1996. It shows a strongly red continuum reflectance and several prominent infrared absorption features. The strongest absorptions in 1993SC's spectrum occur near 1.62, 1.79, 1.95, 2.20, and 2.32 micrometers in wavelength. Features near the same wavelengths in the spectra of Pluto and Neptune's satellite Triton are due to CH4 on their surfaces, suggesting the presence of a simple hydrocarbon ice such as CH4, C2H6, C2H4, or C2H2 on 1993SC. In addition, the red continuum reflectance of 1993SC suggests the presence of more complex hydrocarbons. PMID:9163038

    The known biophysical variations of hemoglobin (Hb) S and Hb C may result in hemodynamic differences between subjects with SS and SC disease. The purpose of this study was to measure and compare conjunctival hemodynamics between subjects with Hb SS and SC hemoglobinopathies. Image sequences of the conjunctival microcirculation were acquired in 9 healthy control subjects (Hb AA), 24 subjects with SC disease, and 18 subjects with SS disease, using a prototype imaging system. Diameter (D) and blood velocity (V) measurements were obtained in multiple venules of each subject. Data were categorized according to venule caliber by averaging V and D for venules with diameters less than (vessel size 1) or greater than (vessel size 2) 15 µm. V in vessel size 2 was significantly greater than V in vessel size 1 in the AA and SS groups (P ≥ 0.009), but not in the SC group (P = 0.1). V was significantly lower in the SC group as compared to the SS group (P = 0.03). In AA and SS groups, V correlated with D (P ≥ 0.005), but the correlation was not statistically significant in the SC group (P = 0.08). V was inversely correlated with hematocrit in the SS group for large vessels (P = 0.03); however, no significant correlation was found in the SC group (P ≥ 0.2). Quantitative assessment of conjunctival microvascular hemodynamics in SS and SC disease may advance understanding of sickle cell disease pathophysiology and thereby improve therapeutic interventions.

    Chesterfield County is located in the north central part of South Carolina (SC) and is adjacent to the North Carolina border. The County lies along the Fall Line, the geologic boundary between the Atlantic Coastal Plain (ACP) and Piedmont physiographic provinces. Between 2000 and 2007, the population increased from 42,768 to 43,191 people (U.S. Census Bureau, 2007). Associated with this population growth is an increased demand for domestic, public, industrial, and agricultural water supplies. The ACP sediments underlying Chesterfield County contain abundant supplies of highquality groundwater (Newcome, 2004). The U.S. Geological Survey, in cooperation with the South Carolina Department of Natural Resources is investigating the ACP groundwater resources of Chesterfield County. The initial task of the study is to establish a hydrologic data-collection network for the ACP part of the County. A groundwater-flow model and derived water budgets for the ACP aquifer that underlies most of the County will be constructed and calibrated later in the study. Both anthropogenic and natural groundwater contaminants that have been identified in the study area will be quantified and described as part of a companion study.

    Bonding in the low-lying states of ScO, ScS, VO, and VS is theoretically studied. Excellent agreement is obtained with experimental spectroscopic constants for the low-lying states of ScO and VO. The results for VS and ScS show that the bonding in the oxides and sulfides is similar, but that the smaller electronegativity in S leads to a smaller ionic component in the bonding. The computed D0 of the sulfides are about 86 percent of the corresponding oxides, and the low-lying excited states are lower in the sulfides than in the corresponding oxides. The CPF method is shown to be an accurate and cost-effective method for obtaining reliable spectroscopic constants for these systems.

    Snohomish County in western Washington State began converting its vehicle fleet to use a blend of biodiesel and petroleum diesel in 2005. As prices for biodiesel rose due to increased demand for this cleaner-burning fuel, Snohomish County looked to its farmers to “grow” this fuel locally. Suitable seed crops that can be crushed to extract oil for use as biodiesel feedstock include canola, mustard, and camelina. The residue, or mash, has high value as an animal feed. County farmers began with 52 acres of canola and mustard crops in 2006, increasing to 250 acres and 356 tons in 2008. In 2009, this number decreased to about 150 acres and 300 tons due to increased price for mustard seed.

    Abstract - Breeding records of Accipiter striatus (Sharp-shinned Hawks) in the southeastern US are scattered and isolated. We documented a Sharp-shinned Hawk and Accipiter cooperii (Cooper’s Hawk) nest while conducting a telemetry study on Melanerpes erythrocephalus (Red-headed Woodpeckers) in Barnwell County, SC in 2006 and 2007. We report the first known nest of a Sharp-shinned Hawk in Barnwell County, SC and the first report of Sharp-shinned Hawks preying upon Red-headed Woodpeckers. Thirteen of 93 (13.9 %) woodpeckers were killed by accipiters in the summers of 2006 and 2007. Large, contiguous forests managed for Picoides borealis (Red-cockaded Woodpeckers) may be used by breeding Sharp-shinned Hawks. The bright plumage, loud calls, and behavior of Red-headed Woodpeckers, particularly during the nestling stage, may make them conspicuous prey for accipiters.

    1976-01-01

    Lake County includes a 1,150 square-mile area consisting of ridges, uplands, and valleys in central-peninsular Florida. About 32 percent of the county is covered by lakes, swamps, and marshes. Water requirements in 1970 averaged about 54 million gallons per day. About 85 percent of the water was obtained from wells; about 15 percent from lakes. The Floridan aquifer supplies almost all the ground water used in Lake County. Annual recharge to the Floridan aquifer averages about 7 inches over the county; runoff average 8.5 inches. The quality of ground and surface water in Lake County is in general good enough for most uses; however, the poor quality of Floridan-aquifer water in the St. John River Valley probably results from the upward movement of saline water along a fault zone. Surface water in Lake County is usually less mineralized than ground water but is more turbid and colored. (Woodard-USGS)

    Being stimulated by the previously reported large amplitude (202 nT at Kakioka) geomagnetic sudden commencement (SC) on 24 March 1991, we searched larger amplitude SCs in the past. We tried to collect old magnetograms and used the list of SC observed at Kakioka (27.5° gm.lat.) for the period 1924 to 2013 and Colaba (10.5°)-Alibag (10.3°) for 1868 to 1967. We found that the largest amplitude SC occurred on 24 March (the same day as 1991 SC), 1940. The H-component amplitude is larger than 273 nT at Kakioka and 310 nT at Alibag. We could also obtain the copy of the magnetogram of Cape Town (-33.3°) which shows 164 nT amplitude. The statistical analysis shows that the occurrence rate of SCs is less than 5% for amplitude larger than 50 nT and less than 1% for amplitude larger than 100 nT at both Kakioka and Alibag. Large amplitude SCs tend to occur during the declining phase of the solar activity. Finally, we discussed the possible increase of the dynamic pressure associated with the interplanetary shock causing the largest SC.

    We present a computational study of spontaneous polarization and piezoelectricity in Sc(x)Al(1-x)N alloys in the compositional range from x = 0 to x = 0.5, obtained in the context of density functional theory and the Berry-phase theory of electric polarization using large periodic supercells. We report composition-dependent values of piezoelectric coefficients e(ij), piezoelectric moduli d(ij) and elastic constants C(ij). The theoretical findings are complemented with experimental measurement of e33 for a series of sputtered ScAlN films carried out with a piezoelectric resonator. The rapid increase with Sc content of the piezoelectric response reported in previous studies is confirmed for the available data. A detailed description of the full methodology required to calculate the piezoelectric properties of ScAlN, with application to other complex alloys, is presented. In particular, we find that the large amount of internal strain present in ScAlN and its intricate relation with electric polarization make configurational sampling and the use of large supercells at different compositions necessary in order to accurately derive the piezoelectric response of the material.

    A number of studies have suggested that macrophages, dendritic cells, and follicular dendritic cells play an important role in the propagation of PrP(Sc). Both accumulation and proteolysis of PrP(Sc) have been demonstrated in peripheral macrophages. Macrophages may act as reservoirs for PrP(Sc) particles if the cells die during transient PrP(Sc) propagation. However, whether cell death plays a role in PrP(Sc) propagation in macrophages remains unclear. In this study, we investigated the possibility of propagation and transmission of PrP(Sc) between dead immune cells and living neural cells. We found that under specific conditions, transient PrP(Sc) propagation occurs in dead cells, indicating that interaction between PrP(C) and PrP(Sc) on plasma membrane lipid rafts might be important for PrP(Sc) propagation. Co-culturing of killed donor PrP(Sc)-infected macrophages with recipient N2a-3 neuroblastoma cells accelerated PrP(Sc) transmission. Our results suggest that cell death may play an important role in PrP(Sc) propagation, whereas transient PrP(Sc) propagation in macrophages has little effect on PrP(Sc) transmission. PMID:25559669

    MADX-SC allows the treatment of frozen space charge using beam-beam elements in a thin lattice, i.e. one can take advantage of the standard set-up of MAD-X lattices without the need for specialized codes for the space-charge (SC) evaluation. The idea is to simulate over many turns without the problem of noise as in the PIC SC codes. For the examples under study, like the PS and RHIC, it would be desirable to simulate up to 1 million turns or more. To this end one had to make an effort to optimize the scalar speed and, most importantly, get a speed-up of approximately a factor of 5 using OpenMP.

    Functionalization of the MXene Sc2C , which has the rare property to realize semiconducting states for various functionalizations including O, F, and OH, is studied with respect to the electronic and thermal behavior. The lowest lattice thermal conductivity is obtained for OH functionalization and an additional 30% decrease can be achieved by confining the phonon mean free path to 100 nm. Despite a relatively low Seebeck coefficient, Sc2C (OH) 2 is a candidate for intermediate-temperature thermoelectric applications due to compensation by a high electrical conductivity and very low lattice thermal conductivity.

    Local water managers usually rely on information produced at the State and regional scale to make water-resource management decisions. Current assessments of hydrologic and water-quality conditions in Polk County, Florida, commonly end at the boundaries of two water management districts (South Florida Water Management District and the Southwest Florida Water Management District), which makes it difficult for managers to determine conditions throughout the county. The last comprehensive water-resources assessment of Polk County was published almost 40 years ago. To address the need for current countywide information, the U.S. Geological Survey began a 3?-year study in 2002 to update information about hydrologic and water-quality conditions in Polk County and identify changes that have occurred. Ground-water use in Polk County has decreased substantially since 1965. In 1965, total ground-water withdrawals in the county were about 350 million gallons per day. In 2002, withdrawals totaled about 285 million gallons per day, of which nearly 95 percent was from the Floridan aquifer system. Water-conservation practices mainly related to the phosphate-mining industry as well as the decrease in the number of mines in operation in Polk County have reduced total water use by about 65 million gallons per day since 1965. Polk County is underlain by three principal hydrogeologic units. The uppermost water-bearing unit is the surficial aquifer system, which is unconfined and composed primarily of clastic deposits. The surficial aquifer system is underlain by the intermediate confining unit, which grades into the intermediate aquifer system and consists of up to two water-bearing zones composed of interbedded clastic and carbonate rocks. The lowermost hydrogeologic unit is the Floridan aquifer system. The Floridan aquifer system, a thick sequence of permeable limestone and dolostone, consists of the Upper Floridan aquifer, a middle semiconfining unit, a middle confining unit, and

  10. Synaptonemal complex (SC) component Zip1 plays a role in meiotic recombination independent of SC polymerization along the chromosomes.

    1996-01-01

    Zip1 is a yeast synaptonemal complex (SC) central region component and is required for normal meiotic recombination and crossover interference. Physical analysis of meiotic recombination in a zip1 mutant reveals the following: Crossovers appear later than normal and at a reduced level. Noncrossover recombinants, in contrast, seem to appear in two phases: (i) a normal number appear with normal timing and (ii) then additional products appear late, at the same time as crossovers. Also, Holliday junctions are present at unusually late times, presumably as precursors to late-appearing products. Red1 is an axial structure component required for formation of cytologically discernible axial elements and SC and maximal levels of recombination. In a red1 mutant, crossovers and noncrossovers occur at coordinately reduced levels but with normal timing. If Zip1 affected recombination exclusively via SC polymerization, a zip1 mutation should confer no recombination defect in a red1 strain background. But a red1 zip1 double mutant exhibits the sum of the two single mutant phenotypes, including the specific deficit of crossovers seen in a zip1 strain. We infer that Zip1 plays at least one role in recombination that does not involve SC polymerization along the chromosomes. Perhaps some Zip1 molecules act first in or around the sites of recombinational interactions to influence the recombination process and thence nucleate SC formation. We propose that a Zip1-dependent, pre-SC transition early in the recombination reaction is an essential component of meiotic crossover control. A molecular basis for crossover/noncrossover differentiation is also suggested. Images Fig. 2 Fig. 3 Fig. 4 Fig. 5 PMID:8799151

    Salmonella enterica serotype Choleraesuis (S. Choleraesuis) usually causes systemic infections in man and needs antimicrobial treatment. Multidrug resistance (MDR) in S. Choleraesuis is thus a great concern in the treatment of systemic non-typhoid salmonellosis. A large plasmid, pSC138, was identified in 2002 from a S. Choleraesuis strain SC-B67 that was resistant to all antimicrobial agents commonly used to treat salmonellosis, including ciprofloxacin and ceftriaxone. Complete DNA sequence of the plasmid had been determined previously (Chiu et al., 2005). In the present study, the sequence of pSC138 was reannotated in detail and compared with several newly sequenced plasmids. Some transposable elements and drug resistance genes were further delineated. Plasmid pSC138 was 138,742 bp in length and consisted of 177 open reading frames (ORFs). While 134 of the ORFs displayed significant identity levels to other plasmid and prokaryotic sequences, the remaining 43 ORFs have not been previously reported. Mobile elements, including two integrons, seven insertion sequences and eight transposons, and a truncated prophage together encompass at least 66,781 bp (48.1%) of the plasmid genome. The sequence of pSC138 consists of three major regions: a large composite transposable region Tn6088 with a Tn21-like backbone inserted by a variety of integrons or transposable elements; a transfer/maintenance region that contains a conserved ISEcp1-mediated transposon-like element Tn6092, carrying an AmpC gene, bla(CMY-2), that confers the ceftriaxone resistance; and a Rep_3 type of replication region. Another seven bacteremic strains of S. Choleraesuis that expressed the same MDR phenotype were identified during 2003-2008. The same Rep_3 type replicase and the bla(CMY-2)-containing, ISEcp1-mediated transposon-like element were found in the MDR isolates, suggesting a successful preservation and dissemination of the MDR plasmid.

    As the first study on metal carbide/cyanide boron clusterfullerenes, the geometries, energies, stabilities and electronic properties of four novel scandium cluster-containing B80 buckyball derivatives, namely Sc2C2@B80, Sc3C2@B80, Sc3CN@B80 and Sc3C2CN@B80, were investigated by means of density functional theory computations. The rather favorable binding energies, which are very close to those of the experimentally abundant carbon fullerene analogues, suggest a considerable possibility to realize these doped boron clusterfullerenes. Their intracluster and cluster-cage bonding natures were thoroughly revealed by various theoretical approaches. In contrast to carbon clusterfullerenes, in which the encaged non-metal atoms mainly play a stabilizing role in the metal clusters, the encapsulated carbon and nitrogen atoms inside the B80 cage covalently bond to the boron framework, resulting in strong cluster-cage interactions. Furthermore, infrared spectra and (11)B nuclear magnetic resonance spectra were simulated and fingerprint peaks were proposed to assist future experimental characterization. PMID:27424658

    2016-01-01

    We report the discovery of a bulk superconducting transition at 3.4 K in the ternary phosphide, ScIrP, which crystallizes in a hexagonal ZrNiAl-type structure without spatial inversion symmetry. On the basis of heat capacity data in a zero magnetic field, ScIrP is suggested to be a weakly-coupled Bardeen-Cooper-Schrieffer superconductor. Alternatively, experimental results under magnetic fields indicate that this material is a type-II superconductor with an upper critical field Hc2 at magnetic fields above 5 T at zero temperature. This moderately high Hc2 does not violate the Pauli limit, but it does imply that there is a significant effect from the strong spin-orbit interaction of Ir 5d electrons in the noncentrosymmetric crystal structure. Electronic structure calculations show an interesting feature of ScIrP, where both the Sc 3d and Ir 5d orbitals contribute to the electronic density of states at the Fermi level.

  3. Largest geomagnetic sudden commencement (SC) and interplanetary shock

    NASA Astrophysics Data System (ADS)

    Araki, Tohru

    2015-04-01

    The long term variation of amplitude of geomagnetic sudden commencements (SCs) is examined by checking old magnetograms at Kakioka (27.5 deg. geomagnetic latitude) and Alibag (10.3 deg.) and SC lists prepared by both stations. We found that the SC occurred on March 24, 1940 was largest since 1868. The amplitude is 310 nT at Alibag and larger than 273 nT at Kakioka. The magnetogram of Cape Town (-33.3 deg) was also available for this event which shows 164 nT amplitude. This SC occurred during the main phase of a large magnetic storm which has been interested as one of space weather events. The statistical analysis shows that the occurrence probability is less than 5 % for SCs with amplitude larger than 50 nT and less than 1 % for SCs larger than 100 nT at both Kakioka and Alibag. Large amplitude SCs tend to occur in the declining phase of the sun spot cycle as is reported for magnetic storms. Siscoe et al. (1968) firstly proposed the relationship for the solar wind dynamic pressure P and SC amplitude, dH as dH = C*d(P^0.5) where d(P^0.5) shows a jump of the square root of P associated with interplanetary shocks. If we take the proportionality constant C as 15 nT/(nPa)^0.5 and the 300 nT SC amplitude (dH) needs pressure jump from 2 nPa (assumed dynamic pressure in front of the shock) to 460 nPa. If the non-linear effect for magnetospheric compression is taken into account, a larger dynamic pressure will be needed for this large amplitude SC. On the other hand, the proportionality constant, C, might become larger for larger amplitude SC because C includes effects of electric currents induced in the earth. Larger amplitude SCs have larger time variation rate by which C becomes larger and the required dynamic pressure increase becomes smaller. We do not know which of the two competing processes is dominant but we consider that the linear estimation of the required dynamic pressure described above may be valid as the first order approximation.

    One hot spring and 33 wells drilled in the county discharge water at temperatures sufficient for direct-use geothermal applications such as process heat and space heating and cooling. Currently, one industry within the county has been identified which may be able to use geothermal energy for its process heat requirements. Also, a computer simulation model was used to predict geothermal energy on line as a function of time under both private and city-owned utility development of the resource.

  9. Acid-base chemistry in the formation of Mackay-type icosahedral clusters: μ3-acidity analysis of Sc-rich phases of the Sc-Ir system.

    2014-05-19

    The crystal structures of intermetallic phases offer a wealth of geometrical features (helices, multishelled clusters, and host-guest motifs) whose formation has yet to be explained or predicted by chemical theory. A recently developed extension of the acid-base concept to metallic systems, the μ3-acidity model, provides an avenue for developing this understanding for intermetallics formed from transition metals. In this Article, we illustrate how this approach can be used to understand one of the most striking geometrical entities to emerge in intermetallic chemistry, the Mackay cluster of icosahedral quasicrystals. We present μ3-acidity analyses, based on DFT-calibrated Hückel calculations, for a series of Sc-Ir intermetallics: ScIr (CsCl-type), Sc2Ir (Ti2Ni-type), Sc11Ir4, and the Mackay cluster containing phases Sc57Ir13 and Sc44Ir7. We begin by illustrating that a μ3-acidity model correctly predicts that each of these phases is stable relative to disproportionation into their neighboring compounds when a common set of Hückel parameters and d-orbital occupancies is used. Next, we explain these results by developing a relationship between the distance distribution of homoatomic contacts within an atom's coordination sphere and the μ3-neutralization it experiences. For a given average homoatomic distance, the role of heteroatomic contacts is higher when the distribution of homoatomic contacts is narrower. This effect is key to the strength of the acid-base neutralization of the Sc-rich phases, where the Sc atoms find a scarcity of Ir atoms from which to obtain neutralization. Under these circumstances, Sc-Ir contacts should be maximized, whereas the number and distance variations of the Sc-Sc contacts should be minimized. These expectations are borne out by the observed crystal structures. In particular, the Mackay clusters of Sc57Ir13 and Sc44Ir7, in which a central Ir atom is icosahedrally coordinated by a pentagonal dodecahedral array of face-sharing Sc

    In this paper, we have studied the structural and electronic properties of ScN and ScAs in zincblende (ZB) and rocksalt (RS) phases. We have employed the full potential linearized augmented plane wave (FP-APW) method within the density functional theory (DFT). Generalized gradient approximation (GGA), due to Perdew-Burke-Ernzerhof (PBE) has been used to estimate the exchange-correlation functional. Our band structure results for ScN shows the metallic nature, whereas ScAs shows the semiconducting behavior. The obtained results are in excellent agreement with earlier reported data.

    2015-10-01

    Recently, the crystal structures and electrochemical properties of the isomers (Sc2S "trapped" in C82) have been reported, in which the Sc2S is located inside the different positions of the C82 cage. In the present work, three isomers of endohedral metallofullerenes Sc2S@C3v(8)-C82 (A, B, and C) have been designed to explore the effect of the position of Sc2S on their interaction energies and nonlinear optical properties. Among three isomers, the Sc2S is located in different positions of the C82 cage: the angles of Sc-S-Sc in A, B, and C are 104.9, 114.8, and 115.7°, respectively. Furthermore, the analysis of natural bond orbital (NBO) charge indicates that the electron-transfer is from the Sc2S to the adjacent carbon atoms of the C82 cage. The interaction energy of B is the smallest among three isomers which is -226.2 kcal mol(-1). It was worth mentioning that their first hyperpolarizabilities (β tot) were studied, we found that their β tot values were related to the positions of Sc2S: C (2100) > B (1191) > A (947 au). We hope that the present work can provide a new strategy to promote the nonlinear optical properties of endohedral metallofullerenes by changing the positions of the encapsulated molecular. Graphical abstract Three isomers of endohedral metallofullerenes Sc2S@C3v(8)-C82 (A, B, and C) have been designed to explore the position effect of Sc2S on the interaction energies and nonlinear optical properties. Among three isomers, the Sc2S in B has the most stable position. Significantly, the first hyperpolarizability is related to the position of Sc2S inside the C82 cage, which provides a novel strategy to enhance the first hyperpolarizability by the Sc2S revolving inside the C82 cage.

    PGRP-SC2, the member of PGRP family, plays an important role in regulation of innate immune response. In this paper, a PGRP-SC2 gene of Nile tilapia, Oreochromis niloticus (designated as On-PGRP-SC2) was cloned and its expression pattern under the infection of Streptococcus agalactiae was investigated. Sequence analysis showed main structural features required for amidase activity were detected in the deduced amino acid sequence of On-PGRP-SC2. In healthy tilapia, the On-PGRP-SC2 transcripts could be detected in all the examined tissues, with the most abundant expression in the muscle. When infected with S. agalactiae, there was a clear time-dependent expression pattern of On-PGRP-SC2 in the spleen, head kidney and brain. The assays for the amidase activity suggested that recombinant On-PGRP-SC2 protein had a Zn(2+)-dependent PGN-degrading activity. Moreover, our works showed that recombinant On-PGRP-SC2 protein could significantly reduce bacterial load in target organs attacked by S. agalactiae. These findings indicated that On-PGRP-SC2 may play important roles in the immune response to S. agalactiae in Nile tilapia. PMID:27033804

    Geomagnetic storm connections to solar eruptive phenomena in solar cycle 23 (SC23) have been intensively studied and it is a subject of great importance because of their various effects in our day-to-day life. We analyse the energy transfer from the solar wind into the magnetosphere during intense geomagnetic storms defined by Dst ≤ -150 nT. There were 29 intense storms during SC23. We will use the Akasofu parameter (Akasofu, 1981) to compute the ɛ function and study its time profile. We compute the energy input efficiency during the main phase of the geomagnetic storm. We compute the magnetospheric energy input using the formula introduced by Wang et al. (2014) and compare these results with the ɛ function for the geomagnetic storms of October 29-30, 2003.

    We systematically investigated scandium oxide-doped (and with small amount of rhenium-doped) tungsten bodies for Scandate-type cathodes. Homogeneous microstructure and uniform distribution of scandia were found in these bodies. Sub-micron granular porous bodies with greatly uniformly dispersed scandia are obtained by sintering Sc 2O 3 and Re doped tungsten powder. Such bodies are thought to be beneficial for emission uniformity. For Scandate-type cathodes with such bodies, a slight decrease of scandia was observed by "in situ" AES analysis after ion sputtering, but it recovers completely on reheating. It is assumed that film-like Sc 2O 3 coating over tungsten grains but leaving porous areas for diffusion of barium to the surface leads to good emission properties and high resistance to ion bombardment. Reprocucibility has been proved for the body manufactering process. This offers the possibility of improving the performance of these cathodes in applications such as CRT's.

    Flux-grown ScPO{sub 4} single crystals exhibit a number of luminescence bands in their x-ray-excited luminescence spectra - including sharp lines arising from rare-earth elements plus a number of broad bands at 5.6 cV, 4.4 eV, and 3 eV. The band at 5.6 eV was attributed to a self-trapped exciton (STE) [l], and it could be excited at 7 eV and higher energies. This luminescence is strongly polarized (P = 70 %) along the optical axes of the crystal and exhibits a kinetic decay time constant that varies from several ns at room temperature to {approximately}10 {micro}s at 60 K and up to {approximately}1 ms at 10 K. It is assumed that the STE is localized on the SC ions. The band at 3 eV can be excited in the range of the ScPO{sub 4} crystal transparency (decay time = 3 to 4 {micro}s.) This band is attributed to a lead impurity that creates different luminescence centers. At high temperatures, the band at 4.4 eV is dominant in the x-ray-excited TSL and afterglow spectra. Its intensity increases with irradiation time beginning at zero at the initial irradiation time. The 4.4 eV band does not appear in a fast process under a pulsed electron beam, showing that accumulation is necessary for its observation. A sample of ScPO{sub 4} doped with vanadium exhibited a prevalent band at 4.4 eV at T = 480 K.

    Different couplers are described that allow the reduction of both transverse wake potential and RF kick in the SC acceleration structure of ILC. A simple rotation of the couplers reducing the RF kick and transverse wake kick is discussed for both the main linac and bunch compressors, along with possible limitations of this method. Designs of a coupler unit are presented which preserve axial symmetry of the structure, and provide reduced both the RF kick and transverse wake field.

    The Terrestrial Planet Finder - Occulter (TPF-O) mission has two Spacecraft (SC) buses, one for a space telescope and the other for a formation-flying occulter. SC buses typically supply the utilities (support structures, propulsion, attitude control, power, communications, etc) required by the payloads. Unique requirements for the occulter SC bus are to provide the large delta V required for the slewing maneuvers of the occulter, and comunications for formation flying. The TPF-O telescope SC bus shares some key features of the one for the Hubble Space Telescope (HST): both support space telescopes designed to observe in the visible to near infrared range of wavelengths with comparable primary mirror apertures (2.4 m for HST, 2.4 - 4.0 m for TPF-O). However, TPF-O is expected to have a Wide Field Camera (WFC) with a Field of View (FOV) much larger than that of HST. Ths WFC is also expected to provide fine guidance. TPF-O is designed to operate in an orbit around the Sun-Earth Lagrange 2 (SEL2) point. The longer communications range to SEL2 and the large science FOV require higher performance communications than HST. Maintaining a SEL2 orbit requires TPF-O, unlike HST, to have a propulsion system. The velocity required for reachng SEL2 and the limited capabilities of affordable launch vehicles require both TPF-O elements to have compact, low-mass designs. Finally, it is possible that TPF-O may utilize a modular design derived fiom that of HST to allow servicing in the SEL2 orbit.

    Combinatorial phage display technology offers a new possibility for making human antibodies which could be used in immune therapy. We explored the use of this technology to make human scFvs specific for crotoxin, the main toxic component of the venom of the South-American rattlesnake Crotalus durissus terrificus. Crotoxin, a phospholipase A2 neurotoxin constituted by the association of two subunits, exerts its lethal action by blocking neuromuscular transmission. This is the first report of human anticrotoxin scFvs (scFv 1, scFv 6 and scFv 8) isolated from a naive library of more than 1010 scFv clones with in vivo neutralizing activity. Nevertheless, differences are observed at the level of biological and immunological effects. Only scFv 8 is able to reduce the myotoxicity induced by crotoxin and scFv 1 is capable of altering the in vitro enzymatic activity of this toxin. All three scFvs recognize a region of one subunit located at the junction with the other one. Moreover these scFvs share strong amino acid homologies at the level of either the heavy or the light chain. Taken together, our results suggest that the use of human anticrotoxin scFvs may lead to a new and less aggressive passive immune therapy against poisoning by the venom of Crotalus durissus terrificus.

    The electronic structure and chemical bonding of the recently discovered inverse perovskite Sc3AlN , in comparison to those of ScN and Sc metal, have been investigated by bulk-sensitive soft-x-ray emission spectroscopy. The measured ScL , NK , AlL1 , and AlL2,3 emission spectra are compared with calculated spectra using first-principles density-functional theory including dipole transition-matrix elements. The main Sc3d-N2p and Sc3d-Al3p chemical bond regions are identified at -4 and -1.4eV below the Fermi level, respectively. A strongly modified spectral shape of 3s states in the AlL2,3 emission from Sc3AlN in comparison to that for pure Al metal is found, which reflects the Sc3d-Al3p hybridization observed in the AlL1 emission. The differences between the electronic structures of Sc3AlN , ScN, and Sc metal are discussed in relation to the change in the conductivity and elastic properties.

    Point defect structure of B2 TrSc (Tr =Cd, Ru) alloys was investigated using supercell and special quasi-random structure (SQS) approaches. According to our results, Tr and Sc anti-sites are the constitutional point defects in Tr-rich and Sc-rich B2 TrSc, respectively. To investigate the thermal defect concentrations at finite temperatures, we adopted the Wagner-Schottky model using point defect formation enthalpies obtained from supercell and SQS approaches. The present results suggest that the predominant thermal defects in B2 CdSc are of exchange type, and in B2 RuSc are of interbranch Sc type. The calculated results show an agreement with the available theoretical and experimental data.

    The complexation ability of DOTA analogs bearing one methylenephosphonic (DO3AP) or methylenephosphinic (DO3AP(PrA) and DO3AP(ABn)) acid pendant arm toward scandium was evaluated. Stability constants of their scandium(iii) complexes were determined by potentiometry combined with (45)Sc NMR spectroscopy. The stability constants of the monophosphinate analogues are somewhat lower than that of the Sc-DOTA complex. The phosphorus acid moiety interacts with trivalent scandium even in very acidic solutions forming out-of-cage complexes; the strong affinity of the phosphonate group to Sc(iii) precludes stability constant determination of the Sc-DO3AP complex. These results were compared with those obtained by the free-ion selective radiotracer extraction (FISRE) method which is suitable for trace concentrations. FISRE underestimated the stability constants but their relative order was preserved. Nonetheless, as this method is experimentally simple, it is suitable for a quick relative comparison of stability constant values under trace concentrations. Radiolabelling of the ligands with (44)Sc was performed using the radioisotope from two sources, a (44)Ti/(44)Sc generator and (44m)Sc/(44)Sc from a cyclotron. The best radiolabelling conditions for the ligands were pH = 4, 70 °C and 20 min which were, however, not superior to those of the parent DOTA. Nonetheless, in vitro behaviour of the Sc(iii) complexes in the presence of hydroxyapatite and rat serum showed sufficient stability of (44)Sc complexes of these ligands for in vivo applications. PET images and ex vivo biodistribution of the (44)Sc-DO3AP complex performed on healthy Wistar male rats showed no specific bone uptake and rapid clearance through urine. PMID:26675416

    Background Population stratification is a key concern for genetic association analyses. In addition, extreme homogeneity of ethnic origins of a population can make it difficult to interpret how genetic associations in that population may translate into other populations. Here we have evaluated the genetic substructure of samples from the Cache County study relative to the HapMap Reference populations and data from the Alzheimer's Disease Neuroimaging Initiative (ADNI). Results Our findings show that the Cache County study is similar in ethnic diversity to the self-reported "Whites" in the ADNI sample and less homogenous than the HapMap CEU population. Conclusions We conclude that the Cache County study is genetically representative of the general European American population in the USA and is an appropriate population for conducting broadly applicable genetic studies.

    The timely warning of a flood is crucial to the protection of lives and property. One has only to recall the floods of August 2, 1973, September 16 and 17, 1999, and April 16, 2007, in Somerset County, New Jersey, in which lives were lost and major property damage occurred, to realize how costly, especially in terms of human life, an unexpected flood can be. Accurate forecasts and warnings cannot be made, however, without detailed information about precipitation and streamflow in the drainage basin. Since the mid 1960's, the National Weather Service (NWS) has been able to forecast flooding on larger streams in Somerset County, such as the Raritan and Millstone Rivers. Flooding on smaller streams in urban areas was more difficult to predict. In response to this problem the NWS, in cooperation with the Green Brook Flood Control Commission, installed a precipitation gage in North Plainfield, and two flash-flood alarms, one on Green Brook at Seeley Mills and one on Stony Brook at Watchung, in the early 1970's. In 1978, New Jersey's first countywide flood-warning system was installed by the U.S. Geological Survey (USGS) in Somerset County. This system consisted of a network of eight stage and discharge gages equipped with precipitation gages linked by telephone telemetry and eight auxiliary precipitation gages. The gages were installed throughout the county to collect precipitation and runoff data that could be used to improve flood-monitoring capabilities and flood-frequency estimates. Recognizing the need for more detailed hydrologic information for Somerset County, the USGS, in cooperation with Somerset County, designed and installed the Somerset County Flood Information System (SCFIS) in 1990. This system is part of a statewide network of stream gages, precipitation gages, weather stations, and tide gages that collect data in real time. The data provided by the SCFIS improve the flood forecasting ability of the NWS and aid Somerset County and municipal agencies in

    We report on the absolute scale measurement of the x-ray diffuse scattering in the ZnMgSc icosahedral quasicrystal and its periodic approximant. Whereas the diffuse scattering in the approximant is purely accounted for by thermal diffuse scattering, an additional signal is observed in the quasicrystal. It is related to phason fluctuations as indicated by its Q(2)(per) dependence. Moreover, when compared to previous measurements carried out on the i-AlPdMn phase, we find that the amount of diffuse scattering is smaller in the i-ZnMgSc phase, in agreement with larger phason elastic constants in this phase. This is confirmed by the observation of a large number of weak Bragg peaks having a high Q(per) reciprocal space component. PMID:16196940

    The Yuma County Area Development Plan evaluated the county-wide market potential for utilizing geothermal energy. The study identified four potential geothermal resource areas with temperatures less than 90/sup 0/C (194/sup 0/F), and in addition, two areas are inferred to contain geothermal resources with intermediate (90/sup 0/C to 150/sup 0/C, 194/sup 0/F to 300/sup 0/F) temperature potential. The resource areas are isolated, although one resource area is located near Yuma, Arizona. One resource site is inferred to contain a hot dry rock resource. Anticipated population growth in the county is expected to be 2 percent per year over the next 40 years. The primary employment sector is agriculture, though some light industry is located in the county. Water supplies are found to be adequate to support future growth without advese affect on agriculture. Six firms were found in Yuma County which may be able to utilize geothermal energy for process heat needs. In addition, several agricultural processors were found, concentrated in citrus processing and livestock raising. Geothermal energy utilization projections suggest that by the year 2000, geothermal energy may economically provide the energy equivalent of 53,000 barrels of oil per year to the industrial sector if developed privately. Geothermal utilization projections increase to 132,000 barrels of oil per year by 2000 if a municipal utility developed the resource.

    This map portrays the surface and shallow subsurface geology of the greater Charleston, S.C. region east of 80°30′ west and south of 33°15′ north. The region covers the entirety of Charleston County and portions of Berkeley, Colleton, Dorchester, and Georgetown Counties. Units locally exposed at the surface range in age from middle Eocene to Holocene, but most of the area is covered by Quaternary interglacial deposits. These are, from oldest to youngest, the Okefenokee, Waccamaw(?), Penholoway, Ladson, Ten Mile Hill, and Wando Formations and the Silver Bluff beds. Two cross sections, one running southeast from Harleyville to the coastline on James Island and the other running along the coastal barrier islands from the town of Edisto Beach to the northeast end of Bull Island at the southwest edge of Bull Bay, portray the complex geometry of the Paleogene and Neogene marine units that directly lie beneath the Quaternary units. These older units include the Santee Limestone, Tupelo Bay, Parkers Ferry, Ashley, Chandler Bridge, Edisto, Parachucla, and Marks Head Formations, the Goose Creek Limestone, and the Raysor Formation. The estimated locations of deeply buried active basement faults are shown which are responsible for ongoing modern seismicity in the Charleston, S.C. area.

It was made in order to identify possible fault and fracture systems that might be conduits for geothermal fluids. Geothermal fluids commonly utilize fault and fractures in competent rocks as conduits for fluid flow. Geothermal exploration involves finding areas of high near-surface temperature gradients, along with a suitable “plumbing system” that can provide the necessary permeability. Geothermal power plants can sometimes be built where temperature and flow rates are high. To do this, georeferenced topographic maps and aerial photographs were utilized in an existing GIS, using ESRI ArcMap 10.0 software. The USA_Topo_Maps and World_Imagery map layers were chosen from the GIS Server at server.arcgisonline.com, using a UTM Zone 13 NAD27 projection. This line shapefile was then constructed over that which appeared to be through-going structural lineaments in both the aerial photographs and topographic layers, taking care to avoid manmade features such as roads, fence lines, and right-of-ways. These lineaments may be displaced somewhat from their actual location, due to such factors as shadow effects with low sun angles in the aerial photographs. Note: This shape file was constructed as an aid to geothermal exploration in preparation for a site visit for field checking. We make no claims as to the existence of the lineaments, their location, orientation, and nature.

    2016-02-01

    Cells that constitutively diversify their immunoglobulin genes can be used for selection of novel antibodies and for refining existing affinities and specificities. Here, we report an adaptation of the chicken DT40 system wherein its capacity for somatic hypermutation is harnessed to evolve human antibodies expressed as single-chain variable fragments (scFvs). Expression of membrane-anchored scFvs from within the rearranged Igλ locus created self-diversifying scFv libraries from which we could both select scFvs of a desired specificity and evolve both the specificity and affinity of existing scFvs by iterative expansion and selection. From these scFvs, we were able to create fully human IgG antibodies with nanomolar affinities. We further enhanced the functionality of the system by creating a pool of DT40 scFv lines with high levels of mutation driven by the overexpression of a hyperactive variant of activation-induced deaminase. From this library, we successfully isolated scFvs that bound the spliceosome factor CWC15 and the cytokine human IFNγ. Our results demonstrate the flexibility and utility of DT40 for rapid generation of scFv repertoires and efficient selection, evolution and affinity maturation of scFv specificities. PMID:26519451

    The geometric and electronic properties of metal-carbon encaged fullerenes Sc2C2@C84 have been studied using the density functional theory at the Becke exchange gradient correction and the Perdew-Wang correlation gradient correction function level with the double numerical atomic orbitals basis sets augmented by polarization functions. The Sc2C2 cluster was found to be stable in C84 cage, while the cage expands slightly. The Sc2C2 cluster can rotate freely in the cage around the Sc-Sc axis which is coincident with the vertical principal axis of the cage. As the Sc2C2 cluster is encaged, the degeneracy of energy splits, and the HOMO-LUMO energy gap becomes smaller than that of the pure C84, which suggests that Sc2C2@C84 has higher reactivity than C84. Based on our calculated results, the electronic structure of Sc2C2@C84 might be formally described as (Sc2C2)+1@(C84)-1 due to the charge transferring from the Sc2C2 cluster to C84 cage.

    Scandium nitride (ScN) is a rocksalt semiconductor that has attracted significant attention from various researchers for a diverse range of applications. Motivated by the prospect of using its interesting electronic structure for optoelectronic and dilute magnetic semiconductor applications, we present detailed studies of the electronic transport and optical properties of ScN and its alloys with manganese nitride (MnN). Our results suggest (a) dilute manganese doping in ScN compensates for the high n-type carrier concentrations arising due to oxygen impurities and (b) an n-type to p-type carrier type transition occurs at a composition between 5.8% and 11% Mn on Sc sites. In terms of its optical properties, our analysis clearly indicates direct and indirect bandgap absorption edges of ScN located at 2.04 eV and 1.18 eV, respectively. In addition to the direct gap absorption edge, (Sc,Mn)N samples also show Mn-defect induced electronic absorption. Photoluminescence measurements at room temperature from ScN films exhibit a yellowish-green emission corresponding to direct gap radiative recombination. Direct gap recombination is not expected given the smaller indirect gap. A possible role of high excitation intensities in suppressing relaxation and recombination across the indirect bandgap is suspected. Raman spectroscopic and ellipsometric characterization of the dielectric permittivities of ScN and (Sc,Mn)N are also presented to assist in understanding the potential of ScN for optoelectronic applications.

    The full elastic tensor of orthorhombic dysprosium scandate (DyScO3) at room temperature was determined by resonant ultrasound spectroscopy (RUS). Measurements were performed on three 500 μm thick substrates with orientations (110), (100) and (001) in the Pbnm (a < b < c) setting. For this purpose, a modification of the RUS method was developed, enabling simultaneous processing of the resonant spectra of several platelet-shaped samples with different crystallographic orientations. The obtained results are compared with ab initio calculations and with elastic constants of other rare-earth scandates, and are used for discussion of the in-plane elasticity of the (110)-oriented substrate.

    The Pima County Area Development evaluated the county-wide market potential for utilizing geothermal energy. Four potential geothermal resource areas with temperatures less than 1000 C (2120 F) were identified. In addition, one area is identified as having a temperature of 1470 F (2970 F). Geothermal resources are found to occur in Tecson where average population growth rates of two to three percent per year are expected over the next 40 years. Rapid growth in the manufacturing sector and the existence of major copper mines provide opportunities for the direct utilization of geothermal energy. However, available water supplies are identified as a major constraing to projected growth. A regional energy analysis, future predictions for energy consumption, and energy prices are given. Potential geothermal users in Pima County are identified and projections of maximum economic geothermal utilization are given. One hundred fifteen firms in 32 industrial classes have some potential for geothermal use are identified. In addition, 26 agribusiness firms were found in the county.

    Lyons, K.

    1995-10-01

    Hidden in a small industrial corner of Prince Williams County, in Northern Virginia, a composting facility, after its first flourishing year in business, has found itself part of a symbiotic triangle. Along with a landfill and a waste-to-energy (WTE) plant, the composting facility is one of three programs that make up a joint public-private venture and form a interjurisdictional solid waste/refuse exchange agreement. Faced with the prospects of having to close a landfill at the end of the year, a mandate on yard waste collection that was increasing collection tonnage, and no room for further landfill development, Fairfax County, with approximately 900,000 residents, needed help. In a turn-around situation, Prince William County--with approximately 240,000 residents, a low budget, and much space available for development--responded. Together the counties created a solid waste exchange. The basis for the program is a unity between the local governments on some solid waste issues and a composting facility. Composting, specifically yard waste composting, has been among the fastest-growing aspects of waste management. In 1990, the nation was composting 2% of its solid waste. By the end of 1995, according to the US EPA, between 4% and 7% of solid waste will be recovered through composting. The number of yard waste composting facilities operating has increased from 651 in 1988 to more than 3,000 in 1994.

    1988-01-01

    The Dade County Resources Recovery Facility was built for the county and operated by Parsons and Whittemore from 1981 to 1985. It was permitted to process 920,000 tons per year of MSW. Trash was processed into RDF through a two shredder dry system and garbage through a wet process hydrosposal system producing 50% moisture RDF. The RDF was burned in four water tube boilers to produce superheated steam to drive 2-38.5 MW turbine generators. FP and L purchased the generated electricity. The plant ran at 18,000 tons/Wk. for a short time. By early 1985, the plant was in disrepair, the wet process had caused serious equipment erosion and corrosion, especially in the boilers and the wet process had created serious regulatory and public pressure due to odors and emissions. P and W was removed by the county in June 1985 and replaced by Montenay Power Corp. as plant operator. Mountenay has developed and presented to the county a rehabilitation plan to get the plant back to capacity by 1990. The wet process was shutdown in September 1986.

    We report the synthesis and superconducting properties of the ternary phosphide ScRhP. The crystal structure of ScRhP is determined to be the ordered Fe2P type with the hexagonal Pbar{6}2m space group by powder X-ray diffraction experiments. Resistivity, magnetization, and heat capacity data indicate that ScRhP is a bulk superconductor with a transition temperature Tc of 2 K. This Tc is lower than that of its 5d analogue, ScIrP (Tc = 3.4 K), although ScRhP is found to have larger electronic density of states at the Fermi energy and a higher Debye temperature than those of ScIrP.

    2016-01-01

    A series of scandium compounds, namely ScPO4, ScOF, Li3Sc(BO3)2, and CaSc2O4, were prepared according to procedures described in the literature, and then characterised by powder X-ray diffraction and solid-state 45Sc-NMR spectroscopy. By computer fitting, the quadrupolar interaction parameters χ and η, as well as the isotropic chemical shifts δiso were extracted from the NMR spectra. For comparison and site assignment of 45Sc, density functional theory (DFT) calculations of the EFG tensor were carried out with the CASTEP code. For the compounds with a well-defined formal coordination number (CN), a convincing linear correlation between CN and isotropic chemical shift could be established.

  4. Preparation and characterization of Sc doped MgB2 wires

    Grivel, J.-C.; Burdusel, M.

    2016-09-01

    The in-situ technique was used to manufacture scandium (Sc) doped MgB2 wires in a composite Cu-Nb sheath. After reaction at 700 °C, at most 1 at.% Mg was replaced by Sc in the MgB2 phase, without significant influence on its superconducting transition temperature. For higher Sc concentrations in the nominal composition, the formation of Sc-rich impurity phases was evidenced by SEM/EDS observations. The critical current density and accommodation field of the wires are weakly dependant on the Sc content. It is believed that these effects are related more to modifications of the thermal behaviour of the precursor powders revealed by DTA measurements than to actual doping. The best performance was obtained in a wire with Mg:Sc = 0.995_0.005 atomic ratio.

IL-33 is widely expressed in multiple tissues and cells, and mainly involved in regulating Th2 immune and inflammatory responses. Inhibiting IL-33 signaling pathways relieves the symptoms of allergic inflammation, indicating that IL-33 is a potential target for the treatment of allergic diseases. In this study, the recombinant vectors SP-scFv-Fc/pcDNA3.1 and SP-scFv-Fc/PMH3(EN) were constructed to express a human scFv-Fcs against IL-33. The size of the inserted SP-scFv-Fc was approximately 1540bp. The RT-PCR results showed that SP-scFv-Fcs were successfully transfected into CHO K1 cells. Western blot analysis indicated specific binding of the expressed scFv-Fcs fusion protein (approximately 60kDa under reduced condition) with a goat anti-human IgG1 Fc antibody. The expression level of the scFv-Fcs from SP-scFv-Fc/PMH3(EN) was higher than that from SP-scFv-Fc/pcDNA3.1. A single high-expressing cell line was selected after three rounds of screening and the fusion protein was expressed in a suspension culture in serum-free medium. The level of expression products reached 20mg/L and the expressed and purified scFvs was further characterized and analyzed for bioactivity and functionality. The recombinant vectors for eukaryotic expression of scFv-Fcs against IL-33 were successfully constructed and the expressed scFv-Fcs was shown to be a suitable candidate for the development of a new therapy for allergic and autoimmune diseases.

    Polycrystalline Er-Sc silicates (Er x Sc2- x Si2O7 and Er x Sc2- x SiO5) were fabricated using multilayer nanostructured films of Er2O3/SiO2/Sc2O3 deposited on SiO2/Si substrates by RF sputtering and thermal annealing at high temperature. The films were characterized by synchrotron radiation grazing incidence X-ray diffraction, cross-sectional transmission electron microscopy, energy-dispersive X-ray spectroscopy, and micro-photoluminescence measurements. The Er-Sc silicate phase Er x Sc2- x Si2O7 is the dominant film, and Er and Sc are homogeneously distributed after thermal treatment because of the excess of oxygen from SiO2 interlayers. The Er concentration of 6.7 × 1021 atoms/cm3 was achieved due to the presence of Sc that dilutes the Er concentration and generates concentration quenching. During silicate formation, the erbium diffusion coefficient in the silicate phase is estimated to be 1 × 10-15 cm2/s at 1,250°C. The dominant Er x Sc2 - x Si2O7 layer shows a room-temperature photoluminescence peak at 1,537 nm with the full width at half maximum (FWHM) of 1.6 nm. The peak emission shift compared to that of the Y-Er silicate (where Y and Er have almost the same ionic radii) and the narrow FWHM are due to the small ionic radii of Sc3+ which enhance the crystal field strength affecting the optical properties of Er3+ ions located at the well-defined lattice sites of the Sc silicate. The Er-Sc silicate with narrow FWHM opens a promising way to prepare photonic crystal light-emitting devices.

    The preparation of 3d-transition metal-doped EuO thin films by molecular beam epitaxy is investigated using the example of Sc doping. The Sc-doped EuO samples display a good crystalline structure, despite the relatively small ionic radius of the dopant. The Sc doping leads to an enhancement of the Curie temperature to up to 125 K, remarkably similar to previous observations on lanthanide-doped EuO.

    The structure and phase composition of Al-Ca-Mg-Sc alloys containing 0.3 wt % Sc, up to 10 wt % Ca, and up to 10 wt % Mg have been investigated in the cast state and state after heat treatment. It has been shown that only binary phases Al4Ca, Al3Sc, and Al3Mg2 can be in equilibrium with the aluminum solid solution. It has been found that the maximum strengthening effect caused by the precipitation of Al3Sc nanoparticles for all investigated alloys is attained after annealing at 300-350°C.

    An experimental protocol was developed to screen high-affinity single-chain Fv antibody fragments (scFvs) from a Xanthomonas axonopodis pv. citri (Xac) immunized ribosome display library using BIAcore biosensor. The screening methods involved immobilizing antigen [lipopolysaccharides (LPS) of Xac] on sensor chip HPA and then unpurified expression products of scFvs flowing over the immobilized sensor chip. The affinity-improved scFvs were selected based on dissociation rate constants (k (d)). Thirty-five enzyme-linked immunosorbent assay-positive scFvs were analyzed by BIAcore, and three of those (scFv A1, B2, and C5) with lower k (d) were screened. To demonstrate the accuracy of the screening method, the three scFvs were expressed in Escherichia coli HB2151 and purified. The purified scFvs were subsequently further identified according to association rate and affinity constants. The results showed that the three scFvs (A1, B2, and C5) had high affinity for LPS of Xac (3.51 x 10(-11), 1.13 x 10(-10), 5.06 x 10(-10) M, respectively). Furthermore, the scFv B2 was highly specific for LPS of Xac and had no any cross-reactions with bovine serum albumin and LPS from Xac-related bacteria. This provided evidence that the information from the BIAcore screening assay could be accurate. PMID:18574567

    We investigated PrP(Sc) transmission in neuronal cells, spleen cells and several immune cells using an in vitro cell-to-cell transmission system. The transmission of PrP(Sc) in the supernatant of PrP(Sc)-infected neuronal cells was also investigated. We found that PrP(Sc) transmission was more efficient in the cell-to-cell transmission system than in the supernatant-mediated system. PrP(Sc) was more efficiently transmitted from adherent spleen cells to neuronal cells than from floating spleen cells. The adherent spleen cells were composed of macrophages (80%), dendritic cells (8%) and follicular dendritic cells (3%), indicating that macrophages play an important role in PrP(Sc) transmission from immune cells to neuronal cells. Although PrP(Sc) in the immune cells used as donor cells was gradually degraded, the PrP(Sc) transmitted to neuronal cells was observed by Western blot analysis. Investigation of the mechanism of PrP(Sc) transmission between cells represents an important step towards understanding the pathogenesis of prion diseases. PMID:23246505

    The nuclear level density and the γ-ray strength function have been determined for 43Sc in the energy range up to 2 MeV below the neutron separation energy using the Oslo method with the 46Ti(p,α)43Sc reaction. A comparison to 45Sc shows that the level density of 43Sc is smaller by an approximately constant factor of two. This behavior is well reproduced in a microscopic, combinatorial model calculation. The γ-ray strength function increases at low γ-ray energies, a feature which has been observed in several nuclei but which still awaits theoretical explanation.

    The scute (sc) gene, a member of the achaete-scute complex of Drosophila melanogaster, has dual functions: sisterless (sis-b) function required for sex determination and dosage compensation and scute function, which is involved in neurogenesis. The sc homologue of D. subobscura was cloned. It lacks introns and encodes a single 1.7-kb transcript slightly larger than that of D. melanogaster (1.6 kb). The Sc protein of D. subobscura is slightly larger than that of D. melanogaster (382 vs. 345 amino acids). Sequence comparisons between both species show the Sc protein to have a highly conserved bHLH domain. Outside this domain, amino acid replacements are not randomly distributed. Two additional conserved domains, of 20 and 36 amino acids, are present near the C-terminal end. They may represent domains confering specificity upon the Sc protein with respect to other proteins of the achaete-scute complex. In its 3' untranslated region, Sc RNA contains uridine stretches, putative Sxl protein DNA-binding sites. The D. subobscura Sc protein can cooperate with other D. melanogaster bHLH proteins because D. subobscura sc supplies sis-b function when introduced into D. melanogaster transgenic flies mutant for sc.

    This document highlights the Discom's Distance computing and communication team activities at the 2000 Supercomputing conference in Dallas Texas. This conference is sponsored by the IEEE and ACM. Sandia's participation in the conference has now spanned a decade, for the last five years Sandia National Laboratories, Los Alamos National Lab and Lawrence Livermore National Lab have come together at the conference under the DOE's ASCI, Accelerated Strategic Computing Initiatives, Program rubric to demonstrate ASCI's emerging capabilities in computational science and our combined expertise in high performance computer science and communication networking developments within the program. At SC 2000, DISCOM demonstrated an infrastructure. DISCOM2 uses this forum to demonstrate and focus communication and pre-standard implementation of 10 Gigabit Ethernet, the first gigabyte per second data IP network transfer application, and VPN technology that enabled a remote Distributed Resource Management tools demonstration. Additionally a national OC48 POS network was constructed to support applications running between the show floor and home facilities. This network created the opportunity to test PSE's Parallel File Transfer Protocol (PFTP) across a network that had similar speed and distances as the then proposed DISCOM WAN. The SCINET SC2000 showcased wireless networking and the networking team had the opportunity to explore this emerging technology while on the booth. This paper documents those accomplishments, discusses the details of their convention exhibit floor. We also supported the production networking needs of the implementation, and describes how these demonstrations supports DISCOM overall strategies in high performance computing networking.

    Aluminum alloyed with approximately 1,000 at. ppm Sc was studied by high-pressure energy dispersive X-ray diffraction in two different states, homogenized and aged to peak microhardness. The microhardness of the aged sample is about three times higher than the microhardness of the homogenized sample (as a result of the formation of nanosize Al{sub 3}Sc precipitates in the aged sample). The results, which were refined using the Rietveld analysis technique, indicate a single cubic phase with no phase transition up to a pressure of 32 GPa. The Vinet equation was used to fit the volume-pressure curve to the equation-of-state. The bulk modulus (B{sub 0}) is found to be 73 {+-} 5 GPa, and is equal to the value measured for an unalloyed aluminum sample. The fact that the bulk modulus does not change, despite a large difference in microhardness between the samples, is the result of the different origins of the two quantities.

    In this work, we calculate dynamic polarizabilities and hyperfine-structure A and B constants of a few low-lying states for Sc2 +. The sum-over-states technique is applied to calculate the polarizabilities of the 3 d 2D3 /2 ,3 d 2D5 /2 , and 4 s 2S1 /2 states. The most important and correlation sensitive part of the sum is calculated using a highly correlated relativistic coupled-cluster theory. The remaining part of the sum is calculated using a lower-order many-body perturbation theory and the Dirac-Fock theory. Present dynamic polarizabilities are important to investigate the Stark shifts in the 4 s 2S1 /2 - 3 d 2D5 /2 and 4 s 2S1 /2 - 3 d 2D3 /2 clock transitions of Sc2 +. Magic wavelengths for zero Stark shifts corresponding to these transitions are found in the vacuum-ultraviolet region. The coupled-cluster theory is used to estimate the hyperfine A and B constants with a very high accuracy.

    Multilayer mirrors for the extreme ultraviolet (EUV) are keyelements for numerous applications of coherent EUV sources such as newtabletop lasers and free-electron lasers. However the field ofapplications is limited by the radiation and thermal stability of themultilayers. Taking into account the growing power of EUV sources thestability of the optics becomes crucial. To overcome this problem it isnecessary to study the degradation of multilayers and try to increasetheir temporal and thermal stability. In this paper we report the resultsof detailed study of structural changes in Sc/Simultilayers when exposedto intense EUV laser pulses. Various types of surface damage such asmelting, boiling, shockwave creation and ablation were observed asirradiation fluencies increase. Cross-sectional TEM study revealed thatthe layer structure was completely destroyed in the upper part ofmultilayer, but still survived below. The layers adjacent tothe substrateremained intact even through the multilayer surface melted down, thoughthe structure of the layers beneath the molten zone was noticeablychanged. The layer structure in this thermally affected zone is similarto that of isothermally annealed samples. All stages of scandium silicideformation such as interdiffusion, solid-state amorphization, silicidecrystallization, etc., are present in the thermally affected zone. Itindicates a thermal nature of the damage mechanism. The tungstendiffusion barriers were applied to the scandium/silicon interfaces. Itwas shown that the barriers inhibited interdiffusion and increased thethermal stability of Sc/Si mirrors.

    Chester County encompasses 760 square miles in southeastern Pennsylvania. Groundwater- quality studies have been conducted in the county over several decades to address specific hydrologic issues. This report compiles and describes water-quality data collected during studies conducted mostly after 1990 and summarizes the data in a county-wide perspective. In this report, water-quality constituents are described in regard to what they are, why the constituents are important, and where constituent concentrations vary relative to geology or land use. Water-quality constituents are grouped into logical units to aid presentation: water-quality constituents measured in the field (pH, alkalinity, specific conductance, and dissolved oxygen), common ions, metals, radionuclides, bacteria, nutrients, pesticides, and volatile organic compounds.Waterquality constituents measured in the field, common ions (except chloride), metals, and radionuclides are discussed relative to geology. Bacteria, nutrients, pesticides, and volatile organic compounds are discussed relative to land use. If the U.S. Environmental Protection Agency (USEPA) or Chester County Health Department has drinkingwater standards for a constituent, the standards are included. Tables and maps are included to assist Chester County residents in understanding the water-quality constituents and their distribution in the county. Ground water in Chester County generally is of good quality and is mostly acidic except in the carbonate rocks and serpentinite, where it is neutral to strongly basic. Calcium carbonate and magnesium carbonate are major constituents of these rocks. Both compounds have high solubility, and, as such, both are major contributors to elevated pH, alkalinity, specific conductance, and the common ions. Elevated pH and alkalinity in carbonate rocks and serpentinite can indicate a potential for scaling in water heaters and household plumbing. Low pH and low alkalinity in the schist, quartzite, and

    2010-01-01

    Background Cells permissive to virus can become refractory to viral replication upon intracellular expression of single chain fragment variable (scFv) antibodies directed towards viral structural or regulatory proteins, or virus-coded enzymes. For example, an intrabody derived from MH-SVM33, a monoclonal antibody against a conserved C-terminal epitope of the HIV-1 matrix protein (MAp17), was found to exert an inhibitory effect on HIV-1 replication. Results Two versions of MH-SVM33-derived scFv were constructed in recombinant baculoviruses (BVs) and expressed in BV-infected Sf9 cells, N-myristoylation-competent scFvG2/p17 and N-myristoylation-incompetent scFvE2/p17 protein, both carrying a C-terminal HA tag. ScFvG2/p17 expression resulted in an insoluble, membrane-associated protein, whereas scFvE2/p17 was recovered in both soluble and membrane-incorporated forms. When coexpressed with the HIV-1 Pr55Gag precursor, scFvG2/p17 and scFvE2/p17 did not show any detectable negative effect on virus-like particle (VLP) assembly and egress, and both failed to be encapsidated in VLP. However, soluble scFvE2/p17 isolated from Sf9 cell lysates was capable of binding to its specific antigen, in the form of a synthetic p17 peptide or as Gag polyprotein-embedded epitope. Significant amounts of scFvE2/p17 were released in the extracellular medium of BV-infected cells in high-molecular weight, pelletable form. This particulate form corresponded to BV particles displaying scFvE2/p17 molecules, inserted into the BV envelope via the scFv N-terminal region. The BV-displayed scFvE2/p17 molecules were found to be immunologically functional, as they reacted with the C-terminal epitope of MAp17. Fusion of the N-terminal 18 amino acid residues from the scFvE2/p17 sequence (N18E2) to another scFv recognizing CD147 (scFv-M6-1B9) conferred the property of BV-display to the resulting chimeric scFv-N18E2/M6. Conclusion Expression of scFvE2/p17 in insect cells using a BV vector resulted in

    We have used first-principles calculations to investigate the trends in mixing thermodynamics of ScN-based solid solutions in the cubic B1 structure. 13 different Sc1-xMxN (M = Y, La, Ti, Zr, Hf, V, Nb, Ta, Gd, Lu, Al, Ga, In) and three different ScN1-xAx (A = P, As, Sb) solid solutions are investigated and their trends for forming disordered or ordered solid solutions or to phase separate are revealed. The results are used to discuss suitable candidate materials for different strategies to reduce the high thermal conductivity in ScN-based systems, a material having otherwise promising thermoelectric properties for medium and high temperature applications. Our results indicate that at a temperature of T = 800 °C, Sc1-xYxN; Sc1-xLaxN; Sc1-xGdxN, Sc1-xGaxN, and Sc1-xInxN; and ScN1-xPx, ScN1-xAsx, and ScN1-xSbx solid solutions have phase separation tendency, and thus, can be used for forming nano-inclusion or superlattices, as they are not intermixing at high temperature. On the other hand, Sc1-xTixN, Sc1-xZrxN, Sc1-xHfxN, and Sc1-xLuxN favor disordered solid solutions at T = 800 °C. Thus, the Sc1-xLuxN system is suggested for a solid solution strategy for phonon scattering as Lu has the same valence as Sc and much larger atomic mass.

    Fibroblast growth factor receptor 3 (FGFR3) is a noted proto-oncogene involved in the pathogenesis of many tumors, so more and more studies focus on the potential use of receptor kinase inhibitor and therapeutic antibodies against FGFR3. In this study, we designed a novel fusion protein containing the single-chain Fv (ScFv) against FGFR3 and 9-arginine, denoted as ScFv-9R. To achieve the high-level production and soluble expression, ScFv and ScFv-9R were fused with small ubiquitin-related modifier (Sumo) by polymerase chain reaction and expressed in Escherichia coli BL21 (DE3). The recombinant bacteria was induced by 0.5 mM isopropyl-β-D-thiogalactopyranoside for 20 h at 20 °C; supernatants of Sumo-ScFv was harvested and purified by DEAE Sepharose FF and Ni-NTA orderly, and supernatants of Sumo-ScFv-9R was harvested and purified by Ni-NTA. After cleaved by the Sumo protease, the recombinant ScFv or ScFv-9R was released from the fusion protein, respectively. The purity of ScFv or ScFV-9R was shown to be higher than 90 %, and their yield reached 3-5 mg per liter of bacterial culture. In vitro data showed that ScFV-9R can attenuate the phosphorylation of FGFR3 and ERK in the absence or presence of FGF9. Gel retardation assay showed that 1 μg of ScFv-9R could efficiently bind to about 4 pmol siRNA. Fluorescent microscope analysis showed that ScFv-9R can efficiently bind and deliver siRNA into RT112 cells. In conclusion, we use Sumo fusion system to acquire high-level production, soluble expression, and bifunctional activity of ScFv-9R in E. coli. Our results also revealed that ScFv-9R, as a novel carrier, may have potential applications in antitumor studies and pharmaceutical development. PMID:24519456

    The valence band offsets of Sc x Ga1‑x N/AlN heterojunctions were measured by x-ray photoelectron spectroscopy (XPS) and were found to increase from 0.42 eV to 0.95 eV as the Sc content x increased from 0 to 0.15. The increase in valence band offset with increasing x is attributed to the corresponding increase in spontaneous polarization of the wurtzite structure. The Sc x Ga1‑x N/AlN heterojunction is type I, similar to other III-nitride-based heterojunctions. The data also indicate that a type II staggered heterojunction, which can enhance spatial charge separation, could be formed if Sc x Ga1‑x N is grown on GaN.

    We have performed 75As and 1H NMR measurements in LaFeAsO1xHx, an isomorphic compound of LaFeAsO1xFx. LaFeAsO1xHx is an electron doped system, and O2- can be replaced with H- up to x = 0.5. LaFeAsO1xHx is known for having double superconducting (SC) domes on H doping. Recently, we discovered that a new antiferromagnetic (AF) phase follows the double SC domes on further H doping, forming a symmetric AF-SC-SC-AF phase alignment in the electronic phase diagram Unlike the AF ordering in the lightly H-doped regime, the AF ordering in the highly H-doped regime is attributed to the nesting between electron pockets. In the conference, we will show the data of both NMR spectra and the relaxation rate 1/T1 in the whole doping region. We will discuss the difference of electronic states between the lightly H-doped AF-SC phases and highly H-doped SC-AF phases.

    Interleukin (IL) 33 plays very important roles in inflammatory and allergic diseases. To select human single-chain Fv fragments (scFvs) against IL-33, a nonimmune phage library system was constructed. The full-length cDNA library was synthesized for amplification of the variable heavy chain (V(H)) and variable light chain (V(L)). By overlapping extension PCR for splicing V(H) and V(L), the full-length scFv library DNA were amplified and then transformed into Escherichia coli TG1. The scFv library was constructed successfully which contained 2.5×10(8) independent clones with full-length scFv inserts. The results of fingerprint maps of the scFvs by BstN I and DNA sequencing from the library at random proved that the library was diverse. The human IL-33 was amplified, expressed, and purified. The purified IL-33 with bioactivity was biotinylated and used as antigen for selection of scFv library by phage display. After three rounds of affinity selection, about 30 % of clones have specific binding activity with IL-33. Five of those with good binding activity were transformed into E. coli strain HB2151 for soluble expression. The selected scFvs were further identified by western blot and sequencing. Those selected scFvs could be used for further research of their effect on inflammatory and allergic diseases such as asthma by blockade of IL-33. PMID:22562552

    Monoclonal antibodies (mAbs) are currently the fastest growing class of therapeutic proteins. Parallel to full-length IgG format the development of recombinant technologies provided the production of smaller recombinant antibody variants. The single-chain variable fragment (scFv) antibody is a minimal form of functional antibody comprised of the variable domains of immunoglobulin light and heavy chains connected by a flexible linker. In most cases, scFvs are expressed in the bacterium E. coli. The production of soluble scFvs under the reducing conditions of the E. coli bacterial cytoplasm is inefficient because of the inability of the disulfide bonds to form. Hence, scFvs are either secreted to the periplasm as soluble proteins or expressed in the cytoplasm as insoluble inclusion bodies and recovered by refolding. The cytoplasmic expression of scFvs as a C-terminal fusion to maltose-binding protein (MBP) provided the high-level production of stable, soluble, and functional fusion protein. The below protocol provides the detailed description of MBP-scFv production in E. coli utilizing two expression systems: pMalc-TNN and pMalc-NHNN. Although the MBP tag does not disrupt the most of antibody activities, the MBP-TNN-scFv product can be cleaved by TEV protease in order to obtain untagged scFv. PMID:24037842

  17. First principles calculations of the Sc adsorption on Si(001)-c(2 × 4)

    NASA Astrophysics Data System (ADS)

    Romero, M. T.; Cocoletzi, Gregorio H.; Takeuchi, Noboru

    2012-09-01

    We have investigated the energetics and the atomic structure of the adsorption of Sc on the Si(001)-c(2 × 4) surface using first principles total energy calculations, within the periodic density functional. The Sc adsorption has been studied at high symmetry sites considering different concentrations. We have first explored the one atom case and then increased the coverage up to a 0.25 of a monolayer of Sc. For the adsorption of one Sc atom we have obtained that the most stable configuration corresponds to the adsorption in the trench between two Si dimers, at the C1 (cave) site. The interaction of the adsorbed Sc with the Si dimers induces a decrease of the dimers buckling amplitude. On the other hand Si dimers without interaction with the adsorbate have buckling amplitudes similar to those of the clean Si surface. When the Sc coverage is increased to two Sc atoms, the most stable structure corresponds to the adsorption at two consecutive V (valley-bridge) sites along the trench between Si dimers, resulting in the weakening of some of the Si dimers bonds. This result indicates that the formation of one dimensional Sc chains on the silicon surface is energetically and kinetically favorable.

    A growing body of evidence demonstrates that Akt may serve as a therapeutic target for treatment of early brain injury following subarachnoid hemorrhage (SAH). The purpose of the current study was to evaluate the neuroprotective effect of Akt specific activator SC79 in an experimental rat model of SAH. SAH was induced by injecting 300 μL of blood into the prechiasmatic cistern. Intracerebroventricular (ICV) injection of SC79 (30 min post-SAH) induced the p-Akt (Ser473) expression in a dose-dependent manner. A single ICV dose treatment of SC79 (100 μg/rat) significantly increased the expression of Bcl-2 and p-GSK-3β (Ser9), decreased the protein levels of Bax, cytoplasm cytochrome c, and cleaved caspase-3, indicating the antiapoptotic effect of SC79. As a result, the number of apoptotic cells was reduced 24 h post SAH. Moreover, SC79 treatment alleviated SAH-induced oxidative stress, restored mitochondrial morphology, and improved neurological deficits. Strikingly, treatment of SC79 provided a beneficial outcome against neurologic deficit with a therapeutic window of at least 4 h post SAH by ICV injection and 30 min post SAH by intraperitoneal injection. Collectively, SC79 exerts its neuroprotective effect likely through the dual activities of antioxidation and antiapoptosis. These data provide a basic platform to consider SC79 as a novel therapeutic agent for treatment of SAH. PMID:26983552

    This report covers research activities, major results and publications supported by DE-SC-000-1481. This project was funded by the DOE OFES-NNSA HEDLP program. It was a joint research program between Rice University and the University of Texas at Austin. The physics of relativistic plasmas was investigated in the context of ultra-intense laser irradiation of high-Z solid targets. Laser experiments using the Texas Petawatt Laser were performed in the summers of 2011, 2012 and 2013. Numerical simulations of laser-plasma interactions were performed using Monte Carlo and Particle-in-Cell codes to design and support these experiments. Astrophysical applications of these results were also investigated.

    2006-08-18

    Experiments at the FLASH linac at DESY have demonstrated that the Higher Order Modes induced in Superconducting Cavities can be used to provide a variety of beam and cavity diagnostics. The centers of the cavities can be determined from the beam orbit which produces minimum power in the dipole HOM modes. The phase and amplitude of the dipole modes can be used as a high resolution beam position monitor, and the phase of the monopole modes to measure the beam phase relative to the accelerator RF. Beam orbit feedback which minimizes the dipole HOM power in a set of structures has been demonstrated. For most SC accelerators, the existing HOM couplers provide the necessary signals, and the down mix and digitizing electronics are straightforward, similar to those for a conventional BPM.

    Two-dimensional (2D) materials exhibit different electronic properties than their bulk materials. Here, we present a systematic study of 2D tetragonal materials of ScN and YN using density functional theory calculations. Several thermodynamically stable 2D tetragonal structures were determined, and such novel tetragonal structures have good electronic and optical properties. Both bulk ScN and YN are indirect band gap semiconductors while the electronic structures of 2D ScN and YN are indirect gap semiconductors, with band gaps of 0.62–2.21 eV. The calculated optical spectra suggest that 2D tetragonal ScN and YN nanosheets have high visible light absorption efficiency. These electronic properties indicate that 2D ScN and YN have great potential for applications in photovoltaics and photocatalysis.

    Four different methods for measuring the compositions of epitaxial Sc x Ga1‑x N films were assessed and compared to determine which was the most reliable and accurate. The compositions of epitaxial Sc x Ga1‑x N films with 0 ≤ x ≤ 0.26 were measured directly using Rutherford backscattering (RBS) and x-ray photoelectron spectroscopy (XPS), and indirectly using c lattice parameter measurements from x-ray diffraction and c/a ratio measurements from electron diffraction patterns. RBS measurements were taken as a standard reference. XPS was found to underestimate the Sc content, whereas c lattice parameter and c/a ratio were not reliable for composition determination due to the unknown degree of strain relaxation in the film. However, the Sc flux used during growth was found to relate linearly with x and could be used to estimate the Sc content.

    The level densities of {sup 44}Sc and {sup 47}Ti have been determined from measurements of particle evaporation spectra from the compound nuclear reaction {sup 3}He+{sup 45}Sc with an 11 MeV {sup 3}He beam. The level density of {sup 44}Sc has been compared to the level density obtained from an independent experimental method based on an analysis of {alpha}-{gamma} coincidences from the transfer reaction {sup 45}Sc({sup 3}He,{alpha}{gamma}){sup 44}Sc. The good agreement between the two experiments indicates the reliability of the level density obtained. Some level density systematics have been tested against the experimental data. New Fermi-gas level density parameters have been derived.

    1996-01-01

    The geometries of Sc(OH)n+, for n = 1-3, have been optimized using density functional theory, in conjunction with the B3LYP hybrid functional. The zero-point energies are computed at the same level of theory. The successive OH bond energies have been computed at the CCSD(T) level for ScOH+ and Sc(OH)2+. The computed result for ScOD+ is in excellent agreement with the recent experiment of Armentrout and co-workers. There is a dramatic drop for the third OH, because Sc+ has only two valence electrons and therefore the bonding changes when the third OH is added. The difference between the B3LYP and CCSD(T) OH binding energies for the first two OH groups is discussed.

    The SC "Phobos-Grunt" flight is planned to 2009 in Russia with the purpose to deliver to the Earth the soil samples of the Mars satellite Phobos. The mission will pass under the following scheme [1-4]: the SC flight from the Earth to the Mars, the SC transit on the Mars satellite orbit, the motion round the Mars on the observation orbit and on the quasi-synchronous one [5], landing on Phobos, taking of a ground and start in the direction to the Earth. The implementation of complicated dynamical operations in the Phobos vicinity is foreseen by the project. The SC will be in a disturbance sphere of gravitational fields from the Sun, the Mars and the Phobos. The SC orbit determination is carried out on a totality of trajectory measurements executed from ground tracking stations and measurements of autonomous systems onboard space vehicle relatively the Phobos. As ground measurements the radio engineering measurements of range and range rate are used. There are possible as onboard optical observations of the Phobos by a television system and ranges from the SC up to the Phobos surface by laser locator. As soon as the Phobos orbit accuracy is insufficient for a solution of a problem of landing its orbit determination will be carried out together with determination of the SC orbit. Therefore the algorithms for joint improving of initial conditions of the SC and the Phobos are necessary to determine parameters of the SC relative the Phobos motion within a single dynamical motion model. After putting on the martial satellite orbit, on the Phobos observation orbit, on the quasi-synchronous orbit in the Phobos vicinity the equipment guidance and the following process of the SC orbit determination relatively Phobos requires a priori knowledge of the Phobos orbit parameters with sufficiently high precision. These parameters should be obtained beforehand using both all modern observations and historical ones.

    Objective To construct the recombinant human interleukin 4 receptor (rhIL-4R) single-chain Fv (scFv) antibody library by phage display technique to obtain the anti-IL-4R scFv clones selected from the library. Methods Total RNA was extracted from splenocytes of the BALB/c mice immunized with rhIL-4R. Complementary DNA fragments of variable heavy (VH) and variable light (VL) chains of the antibodies were prepared by reverse transcription PCR and assembled into scFv by splice overlap extension PCR (SOE-PCR). Both scFv and the pCANTAB5E vector were respectively double-digested with restriction endonuclease Sfi I and Not I, connected with T4 ligase, and then transformed into the competent cells E.coli TG1; it was cultured in medium to obtain the phage scFv antibody library; after three rounds of enrichment and panning, the specific antigen scFv with high affinity was selected for the sequencing. Results After three rounds of panning, we obtained a diversity of approximately 2×10(8) anti-rhIL-4R scFv antibody library. Sequencing analysis of one positive clone showed that the anti-rhIL-4R scFv was 741 bp and coded 247 amino acids. The analysis of VBASE2 database indicated that VH and VL gene sequences of anti-rhIL-4R protein all had three complementarity determining regions and four backbone areas.Conclusion The anti-rhIL-4R scFv was obtained from the scFv antibody library.

    Novel methods are reported for evaluating and utilizing single chain fragment variable (scFv) antibodies derived from yeast-display libraries. Yeast-display was used to select scFv specific to invariant surface glycoproteins (ISG) of Trypanosoma brucei. A limiting step in the isolation of scFv from nonimmune libraries is the conversion of highly active yeast-displayed scFv into soluble antibodies that can be used in standard immunoassays. Challenges include limited solubility or activity following secretion and purification of scFv. For this reason, few scFv derived from yeast-display platforms have moved into development and implementation as diagnostic reagents. To address this problem, assays were developed that employ both yeastdisplayed and secreted scFv as analytical reagents. The first is a competitive inhibition flow cytometry (CIFC) assay that detects secreted scFv by virtue of its ability to competitively inhibit the binding of biotinylated antigen to yeast-displayed scFv. The second is an epitope binning assay that uses secreted scFv toidentify additional yeast-displayed scFv that bind nonoverlapping or noncompeting epitopes on an antigen. The epitope binning assay was used not only to identify sandwich assay pairs with yeast-displayed scFv, but also to identify active soluble scFv present in low concentration in a crude expression extract. Finally, a CIFC assay was developed that bypasses entirely the need for soluble scFv expression, by using yeast displayed scFv to detect unlabeled antigen in samples. These methods will facilitate the continued development and practical implementation of scFv derived from yeast-display libraries.

    PGRP (peptidoglycan recognition protein) is a conserved protein family that recognizes the peptidoglycan in bacterial cell wall and causes the activation of various innate immune responses. Previous studies have reported that PGRP-SCs in Drosophila dampen the activation of Immune Deficiency (Imd) pathway to microbial infection, and participate in the lifespan extension of the insects. To facilitate understanding the function of PGRP-SCs from an evolutionary angle, we identified and functionally characterized the PGRP-SC gene in the housefly Musca domestica, a species that has adapted to a septic environment much harsher than the natural habitat of Drosophila. The gene designated as MdPGRP-SC was found most abundantly expressed in the 3rd instar larvae, and is expressed at this developmental stage predominantly in the gut. MdPGRP-SC was virtually unchanged in whole larvae after a septic injury at the second larval instar, while two antimicrobial peptides (AMPs), diptericin and attacin, were upregulated in the first 24h but not later. Through dsRNA microinjection, MdPGRP-SC was knocked down by RNA interference (RNAi), and caused the significant increased expression of diptericin and attacin. The pupation of MdPGRP-SC-depleted larvae was severely suppressed compared to controls. Opposite to the expression trend of MdPGRP-SC, a spontaneous active expression of diptericin and attacin was found in pre-pupae but not in third instar larvae. Taken together, our study reveals that downregulation of MdPGRP-SC leads to the overexpression of the AMPs, and is involved in the larvae-to-pupa transition of housefly. PMID:26296288

  19. Environmentally friendly processing of photoresists in scCO2 and decamethyltetrasiloxane

    NASA Astrophysics Data System (ADS)

    2010-04-01

    The chemical waste generated in today's microelectronic fabrication processes has driven the need to develop a more environmentally benign process. Supercritical CO2 (scCO2) has been evaluated as an environmentally friendly solvent for photoresist development. It is nontoxic, nonflammable, and inert under most conditions. It also possesses advantages such as liquid-like densities, gas-like diffusivity, and zero surface tension. Although scCO2 is a poor solvent for most polymers, certain fluorine-and silicon-containing polymers have shown solubility in scCO2. Previously, negative-tone patterns of 100nm have also been developed in scCO2 using conventional photoresists such as ESCAP and PBOCST with the aid of fluorinated quaternary ammonium salts (QAS). However, the incorporation of fluorine degrades plasma etch resistance, and because of their persistence in nature, fluorinated compounds are coming under increased scrutiny. In order to make the process more environmentally benign, the elimination of fluorine is desirable. Some molecular glass photoresists without the incorporation of fluorine and silicon have thus been designed and synthesized to be processed in scCO2. In addition to scCO2, another environmentally friendly, low VOC solvent, decamethyltetrasiloxane has also been investigated to develop conventional photoresists. In this paper, we demonstrate the patterning of photoresists in both scCO2 and decamethyltetrasiloxane.

  20. High throughput screening of scFv antibodies against viral hemorrhagic septicaemia virus by flow cytometry.

    2015-07-01

    Viral hemorrhagic septicaemia (VHS) is an economically important disease that affects salmon and trout worldwide. In this study, a recombinant single chain variable fragment (scFv) antibody library derived from rainbow trout immunized with purified viral hemorrhagic septicaemia virus (VHSV) was constructed. The library was subjected to three rounds of screening by flow cytometry (FCM) against VHSV through a bacteria display technology, resulting in the enrichment of scFv. Four scFv clones with different fluorescence intensity were obtained by colony pick up at random following three rounds of screening. The isolated scFv antibodies were expressed and purified. Relative affinity assay showed the four clones had different sensitivity to VHSV, in accordance with FCM. The potential use of the selected VHSV-specific scFv antibodies was demonstrated by the successful application in Western blotting assay, ELISA and immunofluorescence antibody test (IFAT), and one of the isolated scFv molecular showed excellent in vitro and in vivo blocking activities against VHSV. scFv isolated in this study can be promising diagnostic and/or therapeutic reagents for VHS. This study provides powerful strategies for screening antibodies against new diseases. PMID:25813596

    Single-chain variable fragments (scFvs) specific for tumor-associated cell surface antigens are the most broadly used reagents to direct therapeutic or diagnostic effector molecules, such as toxins, radioisotopes, and CD3-stimulating scFvs, to tumors. One novel class of effector molecules that can be targeted to tumors by scFvs are ligands of the tumor necrosis factor (TNF) family. Typically, these molecules have apoptosis inducing and/or immune stimulating properties and are therefore highly attractive for cancer treatment. N-terminal fusion of scFvs does not interfere with the receptor binding capabilities of TNF ligands and thus allows the straightforward generation of scFv TNF ligand fusion proteins. We report here a protocol for the purification of eukaryotically produced scFv TNF ligand fusion proteins based on affinity chromatography on anti-Flag agarose and further describe assays for the determination of the targeting index of this type of scFv-targeted proteins.

    The U.S. Environmental Protection Agency has not recommended water quality criteria (WQC) to protect aquatic life from elevated sodium and sulfate concentrations, such as those associated with the coal-processing effluent of Meigs County Mine #31. This discharge, received by a tributary of the Leading Creek Watershed (SE Ohio), had a mean specific conductivity (SC) of 8,109 (7,750-8,750) microS/cm and total metal concentrations below acute WQC. The mean 48-h LC(50) for Ceriodaphnia dubia in the effluent was 6,713 +/- 99 microS/cm; mean 48-h survival was 44% for study sites downstream of the effluent. The best indicators of impairment used in this study were Ceriodaphnia fecundity, in situ Corbicula fluminea growth, EPT minus Hydropsychidae (richness and relative abundance), and relative Ephemeroptera abundance. Mayflies, reduced by more than 99% below the effluent, were absent from all but the furthest downstream study site. SC was strongly correlated with Corbicula growth (r = -0.9755, p = 0.0009) and EPT minus Hydropsychidae richness (r = -0.8756, p < 0.0001), suggesting the effluent was primarily responsible for biotic impairment. Our results indicated that SC levels, a measure of dissolved solids, in the Leading Creek Watershed that exceeded approximately 3,700 microS/cm impaired sensitive aquatic fauna. PMID:12712291

    A team led by EngenuitySC has performed education and outreach on development of advanced energy markets that will enable wider use of clean energy technologies. This report details the efforts that have made significant advances to improve the market place through education, outreach, and increased communications between industry members. The project resulted in two self-funded industry clusters known as the Fuel Cell Collaborative and NuHub. This project has focused on building and strengthening the leading clean energy clusters in South Carolina: nuclear energy and fuel cell technologies. For the nuclear industry, a new cluster was developed that is now known as NuHub. This cluster has already engaged over 25 nuclear industry leaders or suppliers, four public sector partners, six community economic development foundations, and nearly ten academic partners in a 175 mile radius between Augusta, Georgia and Charlotte, North Carolina. Our outreach has touched over 2,000 stakeholders through the website alone, not including the public audiences and members of the business community reached through news stories and releases that were distributed to over 620 print and online publications. NuHub has established a formal leadership structure, developed subcommittees to focus on industry issues, instituted educational programs for the workforce, and created an industry funding structure that will sustain the industry cluster and mission. NuHub has participated in a wide-variety of community building and outreach activities since its formation under this grant. In the two years since its creation in 2010, we have initiated efforts focused in four main areas that correlate with the four NuHub subcommittees including: innovation, workforce development, industry engagement, and marketing and communications. NuHub successfully raised over $160,000 in both public and private funding, which has supported work to grow the cluster and engage partners including NuScale, Fluor, and

    DOE grant DE-SC0005904 was allocated to fund the faculty development, curriculum development and travel to support the four institutions of the Connecticut State University System’s (CSUS) Initiative for Nanotechnology-related Equipment, Faculty Development and Curriculum Development. DOE grant DE-SC0005072 was also awarded for this program. In 2010, CSUS had identified the establishment of nanotechnology programs and infrastructure as a priority. At that time, the system set the goal of establishing an academic initiative in nanotechnology for the CSUS, beginning with the development of a series of courses at the graduate level. Implementation was planned via a collaborative effort including faculty from all four of the CSUS campuses. The CSUS Nanotechnology Working Group [CSUS NWG] was established to accomplish this goal. A faculty member from the Physics Department at Southern Connecticut State University [SCSU] was assigned the task of organizing and coordinating the work of the CSUS NWG. Representatives from each of the four CSUS campuses were appointed to join the CSUS NWG with the following initial representation: SCSU [Physics and Biology], Western Connecticut State University (WCSU) [Chemistry], Eastern Connecticut State University (ECSU) [Chemistry] and Central Connecticut State University (CCSU) [Chemistry. As a further outcome it was determined that this collaborative effort would lead to the establishment of a formal nanotechnology center, serving as the nucleus of CSUS student and faculty learning and research. This CSUS Nanotechnology Center [CSUS-NC] was to be located at Southern Connecticut State University (SCSU). The goal of this grant was to provide funding for curriculum and faculty development necessary to facilitate the development and implementation of a collaborative Graduate Certificate in Nanotechnology for the Connecticut State University System. This outcome has been successfully achieved. The courses and structure of the Graduate

    Colorless single crystals of Li{sub 3}ScF{sub 6} have been prepared by reacting the binary components LiF and ScF{sub 3} at 820{sup o}C for 16h in argon atmosphere. This complex fluoride is the only stable phase in the system LiF-ScF{sub 3} under ambient pressure. According to a structure refinement based on single crystal X-ray diffraction data it crystallizes in the centrosymmetric space group P3-bar c1 with a=8.78.3(1)A and c=9.518(1)A. The new structure of Li{sub 3}ScF{sub 6} is a filled variant of the Na{sub 2}GeF{sub 6} type structure and can be described in terms of a hexagonal close packing of fluorine in which 2/3 of the octahedral holes are occupied by Sc and Li. High pressure/high temperature studies of the system LiF-ScF{sub 3} show that the new phase LiScF{sub 4} is formed at around 5.5GPa and 575{sup o}C. According to Rietveld refinements of powder X-ray diffraction data LiScF{sub 4} adopts the Scheelite type structure (space group I4{sub 1}/a) with a=4.980(1)A and c=10.074(1)A. A sample of LiScF{sub 4} doped with 1% Er exhibits an intense luminescence in the far IR region.

  6. 4SC-202 activates ASK1-dependent mitochondrial apoptosis pathway to inhibit hepatocellular carcinoma cells.

    The aim of the present study is to investigate the potential anti-hepatocellular carcinoma (HCC) cell activity by 4SC-202, a novel class I HDAC inhibitor (HDACi). The associated signaling mechanisms were also analyzed. We showed that 4SC-202 treatment induced potent cytotoxic and proliferation-inhibitory activities against established HCC cell lines (HepG2, HepB3, SMMC-7721) and patient-derived primary HCC cells. Further, adding 4SC-202 in HCC cells activated mitochondrial apoptosis pathway, which was evidenced by mitochondrial permeability transition pore (mPTP) opening, cytochrome C cytosol release and caspase-3/-9 activation. Inhibition of this apoptosis pathway, by caspase-3/-9 inhibitors, mPTP blockers, or by shRNA-mediated knockdown of cyclophilin-D (Cyp-D, a key component of mPTP), significantly attenuated 4SC-202-induced HCC cell death and apoptosis. Reversely, over-expression of Cyp-D enhanced 4SC-202's sensitivity in HCC cells. Further studies showed that 4SC-202 induced apoptosis signal-regulating kinase 1 (ASK1) activation, causing it translocation to mitochondria and physical association with Cyp-D. This mitochondrial ASK1-Cyp-D complexation appeared required for mediating 4SC-202-induced apoptosis activation. ASK1 stable knockdown by targeted-shRNAs largely inhibited 4SC-202-induced mPTP opening, cytochrome C release, and following HCC cell apoptotic death. Together, we suggest that 4SC-202 activates ASK1-dependent mitochondrial apoptosis pathway to potently inhibit human HCC cells. PMID:26773495

    SC-41930 was evaluated for effects on human neutrophil chemotaxis and degranulation. At concentrations up to 100 microM, SC-41930 alone exhibited no effect on neutrophil migration, but dose-dependently inhibited neutrophil chemotaxis induced by leukotriene B4 (LTB4) in a modified Boyden chamber. Concentrations of SC-41930 from 0.3 microM to 3 microM competitively inhibited LTB4-induced chemotaxis with a pA2 value of 6.35. While inactive at 10 microM against C5a-induced chemotaxis, SC-41930 inhibited N-formyl-methionyl-leucyl-phenylalanine (fMLP)-induced chemotaxis, with 10 times less potency than against LTB4-induced chemotaxis. SC-41930 inhibited (3H)LTB4 and (3H)fMLP binding to their receptor sites on human neutrophils with KD values of 0.2 microM and 2 microM, respectively. SC-41930 also inhibited neutrophil chemotaxis induced by 20-OH LTB or 12(R)-HETE. At concentrations up to 10 microM, SC-41930 alone did not cause neutrophil degranulation, but inhibited LTB4-induced degranulation in a noncompetitive manner. SC-41930 also inhibited fMLP- or C5a-induced degranulation, but was about 8 and 10 times less effective for fMLP and C5a, respectively. The results indicate that SC-41930 is a human neutrophil LTB4 receptor antagonist with greater specificity for LTB4 than for fMLP or C5a receptors.

    A non-immune library of human single chain fragment variable (scFv) antibodies displayed on Saccharomyces cerevisiae was screened for binding to the Clostridium botulinum neurotoxin serotype A binding domain [BoNT/A (Hc)] with the goal of identifying scFv to novel epitopes. To do this, an antibody-mediated labeling strategy was used in which antigen-binding yeast clones were selected after labeling with previously characterized monoclonal antibodies (MAbs) specific to the Hc. Twenty unique scFv clones were isolated that bound Hc. Of these, three also bound to full-length BoNT/A toxin complex with affinities ranging from 5 nM to 170 nM. Epitope binning showed that the three unique clones recognized at least two epitopes that were distinct from one another and from the detection MAbs. After production in E. coli, the scFv were coupled to magnetic particles and tested for their ability to capture BoNT/A holotoxin using an Endopep-MS assay. In this assay, toxin captured by scFv coated magnetic particles was detected by incubation of the complex with a peptide containing a BoNT/A-specific cleavage sequence. Mass spectrometry was used to detect the ratio of intact peptide to cleavage products as evidence for toxin capture. When tested individually, each of the scFv showed a weak positive Endopep-MS result. However, when the particles were coated with all three scFv simultaneously, they exhibited significantly higher Endopep-MS activity, consistent with synergistic binding. These results demonstrate novel approaches toward the isolation and characterization of scFv antibodies specific to unlabeled antigen. They also provide evidence that distinct scFv antibodies can work synergistically to increase the efficiency of antigen capture onto a solid support.

  11. Groundwater management and protection Madison County, Alabama

    SciTech Connect

    French, J.H.; Strunk, J.W.

    1990-07-01

    Groundwater is extremely important to Madison County as it provides nearly three quarters of the county's drinking water. In recent years, Madison County has increasingly recognized the need to protect its groundwater resource. A supply of usable groundwater is one element of a high quality environment, which can help spur economic development and provide for the needs of a growing population. Without planning protection and understanding of possible consequences, however, economic development and population pressures can cause a gradual degradation of groundwater. In April 1987, the Tennessee Valley Authority (TVA) convened a local groundwater steering group in Madison County. At the first meeting the ground agreed upon these goals: (1) to seek incorporate groundwater protection into the planning and development process for Madison County, (2) to support efforts by Madison County to obtain authority to adopt zoning ordinances and subdivision regulations, and (3) to develop a groundwater management plan for the county. This report provides essential information needed in developing a plan and is based on the following assumptions: the citizens of Madison County value the environment in which they live and wish to protect it from pollution; continued economic development is necessary for a healthy local economy; and a healthy economy can be sustained and nurtured, without degradation of the groundwater resource, through countywide planning, education, and participation.

  5. Far infrared properties of the rare-earth scandate DyScO3.

    PubMed

    Baldassarre, L; Perucchi, A; Lupi, S; Dore, P

    2010-09-01

    We present reflectance measurements in the infrared region on a single crystal the rare-earth scandate DyScO(3). Measurements performed between room temperature and 10 K allow us to determine the frequency of the infrared-active phonons, never investigated experimentally, and to get information on their temperature dependence. A comparison with the phonon peak frequency resulting from ab initio computations is also provided. We finally report detailed data on the frequency dependence of the complex refractive index of DyScO(3) in the terahertz region, which is important in the analysis of terahertz measurements on thin films deposited on DyScO(3).

    CASSCF/CCI calculations are presented for the low-lying states of Y3. Comparison of the wave functions for Y3 and Sc3 indicates substantial 4d-5p hybridization in Y3, but little 3d-4p hybridization in Sc3. The increased 4d-5p hybridization leads to stabilization of 4dpi bonding with respect to 4dsigma bonding for equilateral triangle Y3, and also leads to 4d-5p bonding for linear geometries. These effects lead to a different ordering of states for equilateral triangle geometries and a smaller excitation energy to the linear configuration for Y3 as compared to Sc3.

    The half-life of the positron-emitter (44)Sc has been determined by following the decay rate with two measurement systems; an Ionisation Chamber and a HPGe detector. The combination of seven results gives a value of T1/2=4.042 (25)h, about 2% higher than the recommended value of T1/2=3.97 (4)h (Browne, 2011) and with a lower uncertainty. This radionuclide has also been standardised by coincidence counting, and liquid scintillation counting techniques. A (44)Ti/(44)Sc generator developed at CIEMAT was used to obtain the (44)Sc solutions used in all measurements. PMID:26701659

    MXenes, the new 2D transition metal carbides and nitrides, have recently attracted extensive attention due to their diverse applications and excellent performances. However, the thermal and electrical properties of most MXene materials are yet to be studied. In this work, we investigate the electrical and thermal properties of semiconducting Sc2CT2 (T = F, OH) MXenes using first-principles calculations. Both of the Sc2CT2 (T = F, OH) MXenes are determined to show excellent carrier mobilities. The electron mobility in the Sc2CF2 MXene is found to be strongly anisotropic at room temperature, with values of 5.03 × 10(3) and 1.07 × 10(3) cm(2) V(-1) s(-1) in the zigzag and armchair directions, respectively. The predicted electron mobility in the zigzag direction of the Sc2CF2 is nearly four-fold that in the armchair direction of the promising semiconductor phosphorene. In contrast to Sc2CF2, Sc2C(OH)2 presents approximately isotropic electron mobility. The values at room temperature in the zigzag and armchair directions are calculated as 2.06 × 10(3) cm(2) V(-1) s(-1) and 2.19 × 10(3) cm(2) V(-1) s(-1), respectively. In regard to the thermal properties, the thermal conductivities of the Sc2CT2 (T = F, OH) MXenes have been determined. The predicted values are higher than those of most metals and semiconducting low-dimensional materials, such as monolayer MoS2 and phosphorene. In particular, the room-temperature thermal conductivity along the Sc2CF2 armchair direction has been determined to be as high as 472 W m(-1) K(-1) based on a flake length of 5 μm, which is even higher than that of the best traditional conductor silver. The corresponding value in the zigzag direction of Sc2CF2 is calculated to be 178 W m(-1) K(-1). The thermal conductivity in Sc2C(OH)2 is less anisotropic and lower compared to that in Sc2CF2. The room-temperature value in the armchair (zigzag) direction is determined to be 173 W m(-1) K(-1) (107 W m(-1) K(-1)). Based on their excellent

    In February 1983, the US Department of Energy (DOE) identified a location in Deaf Smith County, Texas, as one of nine potentially acceptable sites for a mined geologic repository for spent nuclear fuel and high-level radioactive waste. To determine their suitability, the Deaf Smith County site and the eight other potentially sites have been evaluated in accordance with the DOE's General Guidelines for the Recommendation of Sites for the Nuclear Waste Repositories. The Deaf Smith County site is in the Permian Basin, which is one of five distinct geohydrologic settings considered for the first repository. On the basis of the evaluations reported in this EA, the DOE has found that the Deaf Smith County site is not disqualified under the guidelines. On the basis of these findings, the DOE is nominating the Deaf Smith County site as one of the five sites suitable for characterization. 591 refs., 147 figs., 173 tabs.

    Trivalent lanthanide ions (Ln3+)-doped inorganic nanoparticles (NPs) as potential luminescent bioprobes have been attracting tremendous interest because of their unique upconversion (UC) and downconversion (DC) luminescence properties. NaScF4, as an important host material, has been rarely reported and its crystal structure remains unclear. Herein, based on the single crystal X-ray diffraction, the space group of NaScF4 crystals was determined to be P31 containing multiple sites of Sc3+ with crystallographic site symmetry of C1, which was verified by high-resolution photoluminescence spectroscopy of Eu3+ at low temperature (10 K). Furthermore, monodisperse and size-controllable NaScF4:Ln3+ NPs were synthesized via a facile thermal decomposition method. The biotinylated NaScF4:Er3+/Yb3+ NPs were demonstrated for their applications as a heterogeneous UC luminescence bioprobe to detect avidin with a detection limit of 180 pM. After bioconjugation with amino-terminal fragment (ATF) of urokinase plasminogen activator (uPA), NaScF4:Ln3+ NPs also exhibited specific recognition of cancer cells overexpressed with uPA receptor (uPAR, an important marker of tumor biology and metastasis), showing great potentials in tumor-targeted bioimaging.Trivalent lanthanide ions (Ln3+)-doped inorganic nanoparticles (NPs) as potential luminescent bioprobes have been attracting tremendous interest because of their unique upconversion (UC) and downconversion (DC) luminescence properties.

    Stellar-population syntheses based on absolute spectral energy distributions over the wavelength range from 3300 to 10,400 A are used to determine the stellar content of the nuclear regions of seven nearby Sc galaxies (NGC 628, 1073, 1084, 1637, 2903, 4321, and 5194). A linear-programming procedure is employed to construct models of the overall stellar populations whose spectra closely match those of the seven galaxies. Absolute measurements of the emission-line spectra of the nuclear regions are also provided. It is found that: (1) intrinsic reddening is probably present in each nuclear region; (2) the upper main sequence is substantially populated in most of the models; (3) the lower main sequence contributes insignificantly to the luminosity in all optimal solutions; (4) substantial contributions are made by evolved M stars at long wavelengths in all the models; (5) the model photometric M/L ratios are low, of the order of unity; and (6) the O-B stars arising naturally in the population models are just sufficient to provide the observed nuclear ionization in all the galaxies except NGC 5194, which may be collisionally ionized. The properties of the nuclear regions are shown to be consistent with the existence of a common initial mass function for star formation and a variety of time dependences for the star-formation process. A possibly significant correlation is noted between nuclear stellar content and overall dynamical properties in four of the galaxies.

    A 'liquid He-free' superconducting electron cyclotron resonance ion Source DECRIS-SC, to be used as an injector for the compact IC-100 cyclotron, has been designed and built in cooperation between the FLNR and LHE (JINR). The main feature is that a compact refrigerator of the Gifford-McMahon type is used to cool the solenoid coils. Due to a very small cooling power at 4.2 K (about 1 W) our efforts were aimed at optimizing the magnetic structure and minimizing external heating of the coils. The maximum magnetic-field strengths are 3 and 2 T in the injection and extraction regions, respectively. When the source had been assembled and magnetic field measured, the ion source was immediately installed at the injection line of the cyclotron. During the first tests, which were run only a few days, some problems arose due to a relatively poor efficiency of the beam transport and analyzing line. From the moment of the first reliable beam production up to now the ion source has been operating continuously for the cyclotron tuning and then for the experiment. Some results of the one-year operation are reported.

    Results are presented from a one-neutron knockout experiment at relativistic energies of ≈ 420 A MeV on 51-55Sc using the GSI Fragment Separator as a two-stage magnetic spectrometer and the MINIBALL array for gamma-ray detection. Inclusive longitudinal momentum distributions and cross-sections were measured enabling the determination of the contributions corresponding to knockout from the ν p_{1/2} , ν p_{3/2} , ( L = 1 and ν f_{7/2} , ν f_{5/2} ( L = 3 neutron orbitals. The observed L = 1 and L = 3 contributions are compared with theoretical cross-sections using eikonal knockout theory and spectroscopic factors from shell model calculations using the GXPF1A interaction. The measured inclusive knockout cross-sections generally follow the trends expected theoretically and given by the spectroscopic strength predicted from the shell model calculations. However, the deduced L = 1 cross-sections are generally 30-40% higher while the L = 3 contributions are about a factor of two smaller than predicted. This points to a promotion of neutrons from the ν f_{7/2} to the ν p_{3/2} orbital indicating a weakening of the N = 28 shell gap in these nuclei. While this is not predicted for the phenomenological GXPF1A interaction such a weakening is predicted by recent calculations using realistic low-momentum interactions V_{low k} obtained by evolving a chiral N3LO nucleon-nucleon potential.

    The Fayette County Better Buildings Initiative represented a comprehensive and collaborative approach to promoting and implementing energy efficiency improvements. The initiative was designed to focus on implementing energy efficiency improvements in residential units, while simultaneously supporting general marketing of the benefits of implementing energy efficiency measures. The ultimate goal of Fayette County’s Better Buildings Initiative was to implement a total of 1,067 residential energy efficiency retrofits with a minimum 15% estimated energy efficiency savings per unit. Program partners included: United States Department of Energy, Allegheny Power, and Private Industry Council of Westmoreland-Fayette, Fayette County Redevelopment Authority, and various local partners. The program was open to any Fayette County residents who own their home and meet the prequalifying conditions. The level of assistance offered depended upon household income and commitment to undergo a BPI – Certified Audit and implement energy efficiency measures, which aimed to result in at least a 15% reduction in energy usage. The initiative was designed to focus on implementing energy efficiency improvements in residential units, while simultaneously supporting general marketing of the benefits of implementing energy efficiency measures. Additionally, the program had components that involved recruitment and training for employment of persons in the energy sector (green jobs), as well as marketing and implementation of a commercial or community facilities component. The residential component of Fayette County’s Better Buildings Initiative involved a comprehensive approach, providing assistance to low- moderate- and market-rate homeowners. The initiative will also coordinate activities with local utility providers to further incentivize energy efficiency improvements among qualifying homeowners. The commercial component of Fayette County’s Better Building Initiative involved grants

    Transition metal dichalcogenides (TMDs) have attracted extensive attention due to their appealing properties for device applications. In this work, we explored the structure stability, electronic structure and magnetism of low-dimensional scandium dioxides, ScO2, by using the first-principles calculations. The results demonstrate that bulk ScO2, monolayers and nanoribbons (NRs) are thermodynamically stable, implying a high possibility of fabricating ScO2 nanocrystals in experiments. Despite the metallic characteristics of bulk ScO2, low-dimensional ScO2 possesses various electronic behaviors that can be further modulated by crystal structure and dimensionality. The results also show that the ground states of ScO2 monolayers and NRs are ferromagnetic (FM) with about 1 μ B per ScO2 formula. Our studies expand a new realm in low-dimensional TMDs, with tunable electronic and magnetic properties.

    The complete elastic tensors of SmScO3 and NdScO3 were measured using resonant ultrasound spectroscopy (RUS) in combination with ab-initio calculations. Measurement of the elastic tensor of these recently synthesized single crystal RE scandates is essential for understanding dynamic lattice applications including phonon confinement, strain induced thin film growth and superlattice construction. On average, the experimental elastic constants differed by less than 5% of the theoretical values, further validating the accuracy of modern ab-initio calculations as a means of estimating the initial elastic constants used in RUS measurements.

    In this work we have studied the feasibility of photonuclear production of (47)Ca from (48)Ca for (47)Ca/(47)Sc generators. Photon flux distribution for electron beams of different energies incident on a tungsten converter was calculated using the MCNPX radiation transport code. The (47)Ca production rate dependence on electron beam energy was found and (47)Ca/(47)Sc yields were estimated for a 40MeV electron beam. It was shown that irradiating enriched targets with a 40MeV, 1mA beam will result in tens of MBq g(-1) (few mCi g(-1)) activity of (47)Sc. The results of the simulations were benchmarked by irradiating 22.5g of CaCl2 powder with a 39MeV electron beam incident on a tungsten converter. Measured (47)Ca/(47)Sc activities were found to be in very good agreement with the predictions. PMID:25600103

    Using ab initio calculations, we have studied Sc 2AC with A=Al, Ga, In and Tl. We show that C 2p and Sc 3d as well as A p and Sc 3d states are hybridized, but the antibonding states in the vicinity of the Fermi level weaken the overall bonding. In terms of the chemical bonding, the influence of the size of the A element is minute. Furthermore, the bulk modulus of the corresponding binary transition metal carbide is not conserved in these phases. Therefore, Sc 2AC can be classified as weakly coupled MAX phases according to Sun and co-workers [Z. Sun, D. Music, R. Ahuja, S. Li, J.M. Schneider, Phys. Rev. B 70 (2004) 092102]. It is our ambition that these calculations will stimulate experimental research on these compounds.

    The magnesium alloy AM-SC1 has been developed as a creep-resistant automotive engine block material. This paper outlines its corrosion performance under laboratory test conditions, considering corrosion on both the external and internal surfaces. This study found that AM-SC1 has a corrosion performance comparable to AZ91 when subjected to an aggressive salt-spray environment or in galvanic-coupling environments. This article further demonstrates that, with the appropriate selection of a commercially available engine coolant, the internal corrosion of AM-SC1 can be maintained at a tolerable level. In addition, internal corrosion resistance can be significantly improved by the addition of fluorides to the coolant solution. It is concluded that AM-SC1 can be successfully used in an engine environment provided that some simple corrosion-prevention strategies are adopted.

    Recombinant human anti-tumor necrosis factor (TNF)-α scFv-Fc was expressed in TKO mutant Arabidopsis thaliana seeds using plant-specific codons. Immunoblotting using a human IgG1 antibody detected the expression of anti-TNF-α proteins in plants. Results from qRT-PCR analysis demonstrated that the time of harvest significantly affected the protein yield and quality. Our results indicate that the Phaseolus vulgaris β-phaseolin promoter directed anti-TNF-α scFv-Fc expression in A. thaliana seeds, with a maximum yield obtained at 20-days of development. Although the yield of anti-TNF-α scFv-Fc protein was not very high, accumulation of recombinant proteins in seeds is an attractive and simple method that can be used to purify biologically active anti-TNF-α scFv-Fc.

    Subcutaneous route of administration is highly desirable for protein therapeutics. It improves patient compliance and quality of life1,2, while reducing healthcare cost2. Recent evidence also suggests that sc administration of protein therapeutics can increase tolerability to some treatments such as intravenous immunoglobulin therapy (IVIG) by administering it subcutaneously (subcutaneous immunoglobulin therapy SCIG), which will reduce fluctuation in plasma drug concentration3. Furthermore, sc administration may reduce the risk of systemic infections associated with iv infusion1,2. This route, however, has its challenges especially for large multi-domain proteins. Poor bioavailability and poor scalability from preclinical models are often cited. This commentary will discuss barriers to sc absorption as well as physiological and experimental factors that could affect pharmacokinetics of subcutaneously administered large protein therapeutics in preclinical models. A mechanistic pharmacokinetic model is proposed as a potential tool to address the issue of scalability of sc pharmacokinetic from preclinical models to humans PMID:25411114

    Three-dimensional electron backscatter diffraction, focused ion beam, transmission electron microscopy and energy filtered transmission electron microscopy were employed to investigate the structural information of primary Al{sub 3}(Sc,Zr) phase, i.e. size, shape, element distribution and orientation relationship with the α-Al matrix. It was found that (i) most primary Al{sub 3}(Sc,Zr) phases have a cubic three-dimensional morphology, with a size of about 6–10 μm, (ii) most primary Al{sub 3}(Sc,Zr) phases are located within the α-Al matrix, and exhibit a cube to cube orientation relationship with the α-Al matrix, and (iii) a layer by layer growth was observed within primary Al{sub 3}(Sc,Zr) phases. Al, Cu, Si and Fe are enriched in the α-Al matrix between the layers of cellular eutectic Al{sub 3}(Sc,Zr) phase, while Sc, Ti and Zr are enriched in small Al{sub 3}(Sc,Zr) phases. A peritectic reaction and subsequent eutectic reaction between Al{sub 3}Sc and Al was proposed to interpret the observed layer by layer growth. This paper demonstrates that the presence of impurities (Fe, Si, Cu, Ti) in the diffusion field surrounding the growing Al{sub 3}(Sc,Zr) particle enhances the heterogeneous nucleation of Al{sub 3}(Sc,Zr) phases. - Highlights: • Most fine cubic primary Al{sub 3}(Sc,Zr) phases were observed within the α-Al matrix. • A layer by layer growth within primary Al{sub 3}(Sc,Zr) phase was observed. • A peritectic and subsequent eutectic reaction between Al{sub 3}Sc and Al was proposed. • Impurities in diffusion fields enhance heterogeneous nucleation of Al{sub 3}(Sc,Zr)

    The Costilla County Biodiesel Pilot Project has demonstrated the compatibility of biodiesel technology and economics on a local scale. The project has been committed to making homegrown biodiesel a viable form of community economic development. The project has benefited by reducing risks by building the facility gradually and avoiding large initial outlays of money for facilities and technologies. A primary advantage of this type of community-scale biodiesel production is that it allows for a relatively independent, local solution to fuel production. Successfully using locally sourced feedstocks and putting the fuel into local use emphasizes the feasibility of different business models under the biodiesel tent and that there is more than just a one size fits all template for successful biodiesel production.

    Thin layers of dense limestone of low permeability that occur near the top of the Biscayne aquifer in the vicinity of the north end of Levee 30 in Dade County, Florida are of hydrologic importance because they retard the downward infiltration of ponded water in Conservation Area No. 3. This retarding effect frequently results in high head differentials across the levee. Tests made in a small area adjacent to Levee 30 indicate that the coefficient of transmissibility of the aquifer is 3,600,000 gpd (gallons per day) per foot, and the coefficient of vertical permeability of the dense limestones is 13 gpd per square foot. If ground-water flow beneath the levee is laminar, the total inflow to the Levee 30 Canal from Conservation Area No. 3 will be about 350 mgd (million gallons per day), or 540 cfs (cubic feet per second), per mile length of levee when the head difference across the levee is 10 feet.

  13. Uptake and subcellular partitioning of trivalent metals in a green alga: comparison between Al and Sc.

    Despite 40+ years of research on aluminum (Al) toxicity in aquatic organisms, Al transport mechanisms through biological membranes, and the intracellular fate of Al once assimilated, remain poorly understood. The trivalent metal scandium shares chemical similarities with Al and, unlike Al, it has a convenient radioactive tracer (Sc-46) allowing for relatively simple measurements at environmentally relevant concentrations. Thus, we investigated the potential of Sc to substitute for Al in uptake and intracellular fate studies with the green alga Chlamydomonas reinhardtii. Short-term (<60 min) competitive uptake experiments indicated that Al does not inhibit Sc influx, implying that these metals do not share a common transport mechanism. Also, internalized Al concentrations were ~4 times higher than Sc concentrations after long-term (72 h) exposures under similar conditions (4.5 μM AlT or ScT, 380 μM FT, pH 7.0, 3.8 pM Al calc (3+) and 1.0 pM Sc calc (3+) ). However, interesting similarities were observed in their relative subcellular distributions, suggesting possible common toxicity/tolerance mechanisms. Both metals mostly distributed to the organelles fraction and almost no association was found with the cytosolic proteins. The greatest difference was observed in the cellular debris fraction (membranes and nucleus) where Al was much more concentrated than Sc. However, it is not clear whether or not this fraction contained extracellular metal associated with the algal surface. To summarize, Sc does not seem to be an adequate substitute of Al for transport/uptake studies, but could be for investigations of toxicity/tolerance mechanisms in C. reinhardtii. Further work is needed to verify this latter suggestion. PMID:24048956

    From historical perspective, the recent advancements in better antenna designs, low power circuitry integrations and inexpensive fabrication materials have made possible a miniature counter-measure against Radar, a clutter behaving like a fake target return called Digital Reflection Frequency Modulation (DRFM). Such a military counter-measure have found its way in the commerce as a near field communication known as Radio Frequency Identification (RFID), a passive or active item tag T attached to every readable-writable Smart Card (SC): Passports ID, medical patient ID, biometric ID, driver licenses, book ID, library ID, etc. These avalanche phenomena may be due to the 3 rd Gen phones seeking much more versatile & inexpensive interfaces, than the line-of-sight bar-code optical scan. Despite of the popularity of RFID, the lacking of Authenticity, Privacy and Security (APS) protection restricted somewhat the wide spread commercial, financial, medical, legal, and militarily applications. Conventional APS approach can obfuscate a private passkey K of SC with the tag number T or the reader number R, or both, i.e. only T*K or R*K or both will appear on them, where * denotes an invertible operation, e.g. EXOR, but not limited to it. Then, only the authentic owner, knowing all, can inverse the operation, e.g. EXOR*EXOR= I to find K. However, such an encryption could be easily compromised by a hacker seeking exhaustively by comparison based on those frequently used words. Nevertheless, knowing biological wetware lesson for power of pairs sensors and Radar hardware counter-measure history, we can counter the counter-measure DRFM, instead using one RFID tag per SD, we follow the Nature adopting two ears/tags, e.g. each one holding portions of the ID or simply two different ID's readable only by different modes of the interrogating reader, followed by brain central processor in terms of nonlinear invertible shufflers mixing two ID bits. We prefer to adopt such a hardware

    Infectious bursal disease (IBD) is considered a vital viral disease that threatens the poultry industry worldwide. In this study, a recombinant single chain variable fragment (scFv) antibody library derived from chickens immunized with VP2 protein of infectious bursal disease virus (IBDV) was constructed. The library was subjected to three rounds of screening by flow cytometry (FCM) against VP2/IBDV through a bacteria display technology, resulting in the enrichment of scFvs. Three scFv clones with different fluorescence intensity were obtained by colony pick up at random. The obtained scFv antibodies were expressed and purified. Relative affinity assay showed the three clones had different sensitivity to VP2, in accordance with fluorescence activity cell sorting analysis (FACS). The potential use of the isolated IBDV-specific scFv antibodies was demonstrated by the successful application of these antibodies in Western blotting and ELISA assay. What's more, in vitro neutralization measurement showed that one of the three isolated antibodies possessed the neutralization function against IBDV. This study provides new strategies for screening of antibody library, and scFv antibodies isolated in this study may be utilized as lead candidates for further development of diagnostic or therapeutic antibodies for detection and treatment of IBDV infection.

    Myoglobin is one of the early biomarkers for acute myocardial infarction. Recently, we have screened an antibody with unique rapid reaction kinetics toward human myoglobin antigen. Antibodies with rapid reaction kinetics are thought to be an early IgG form produced during early stage of in vivo immunization. We produced a recombinant scFv fragment for the premature antibody from Escherichia coli using refolding technology. The scFv gene was constructed by connection of the VH–VL sequence with a (Gly4Ser)3 linker. The scFv fragment without the pelB leader sequence was expressed at a high level, but the solubility was extremely low. A high concentration of 8 M urea was used for denaturation. The dilution refolding process in the presence of arginine and the redox reagents GSH and GSSH successfully produced a soluble scFv protein. The resultant refolded scFv protein showed association and dissociation values of 9.32 × 10−4 M−1·s−1 and 6.29 × 10−3 s−1, respectively, with an affinity value exceeding 107 M−1 (kon/koff), maintaining the original rapid reaction kinetics of the premature antibody. The refolded scFv could provide a platform for protein engineering for the clinical application for diagnosis of heart disease and the development of a continuous biosensor. PMID:25530617

    This paper reports the characterization of scandium aluminum nitride (Al1‑x Sc x N, x  =  27%) films and discusses surface acoustic wave (SAW) devices based on them. Both AlScN and AlN films were deposited on silicon by sputtering and possessed columnar microstructures with (0 0 0 2) crystal orientation. The AlScN/Si SAW devices showed improved electromechanical coupling coefficients (K 2, ~2%) compared with pure AlN films (<0.5%). The performance of the two types of devices was also investigated and compared, using acoustofluidics as an example. The AlScN/Si SAW devices achieved much lower threshold powers for the acoustic streaming and pumping of liquid droplets, and the acoustic streaming and pumping velocities were 2  ×  and 3  ×  those of the AlN/Si SAW devices, respectively. Mechanical characterization showed that the Young’s modulus and hardness of the AlN film decreased significantly when Sc was doped, and this was responsible for the decreased acoustic velocity and resonant frequency, and the increased temperature coefficient of frequency, of the AlScN SAW devices.

    The structural properties and the phase transition for scandium carbide (ScC) have been studied in NaCl (B1), CsCl (B2), ZB (B3), WZ (B4), NiAs (B81), WC (B h ), and Pmmn structures by using the pseudopotential plane-wave method in the framework of the density functional theory. Our theoretical results show that the most stable structure is the B1 phase, contrary to the result of Rahim et al. The phase transitions B1 → Pmmn and Pmmn → B2 are predicted at 83.7 and 109.7 GPa, respectively. At the same time, we find that the B3, B4, B81, and B h phases are not stable over the whole pressure range considered. In particular, the elastic constants of Pmmn-ScC under high pressure are obtained successfully. The effects of pressure on the elastic properties of B1-ScC and Pmmn-ScC are also predicted. The Debye temperatures Θ and the sound velocities of these two structures are estimated from the elastic constants, and by analyzing G/ B, the brittle-ductile behavior of ScC is assessed. In addition, the density of states of B1-ScC at high pressures is also discussed.

    A blue-emitting phosphor BaSc2Si3O10:Eu(2+) was synthesized using the conventional solid-state reaction. The crystallographic occupancy of Eu(2+) in the BaSc2Si3O10 matrix was studied based on the Rietveld refinement results and the photoluminescence properties. BaSc2Si3O10 exhibits blue emission ascribed to (3)T2-(1)A1 and (3)T1-(1)A1 charge transfer of SiO4(4-) excited by 360 nm. All the phosphors of BaSc2Si3O10:Eu(2+) exhibit strong broad absorption bands in the near ultraviolet range, and give abnormal blue emission upon 330 nm excitation. The abnormal phenomenon was explored in detail through many pieces of experimental evidence. The concentration of Eu(2+) is optimized to be 3 mol% according to emission intensity and the quenching mechanism is verified to be a quadrupole-quadrupole interaction. The CIE coordinates of BaSc2Si3O10:0.03Eu(2+) are calculated to be (0.15, 0.05) and BaSc2Si3O10:0.03Eu(2+) shows similar thermal stability to commercial BaMgAl10O17:Eu(2+). PMID:26242881

    2016-07-01

    The hydration structure and dynamics of Sc(3+) in aqueous solution have been investigated using a combined approach based on quantum mechanical (QM) calculations, molecular dynamics (MD) simulations, and extended X-ray absorption fine structure (EXAFS) spectroscopy. An effective Sc-water two-body potential has been generated from QM calculations and then used in the MD simulation of Sc(3+) in water, and the reliability of the entire procedure has been assessed by comparing the theoretical structural results with the EXAFS experimental data. The outstanding outcome of this work is that the Sc(3+) ion forms a well-defined capped square antiprism (SAP) complex in aqueous solution, where the eight water molecules closest to the ion are located at the vertexes of a SAP polyhedron, while the ninth water molecule occupying the capping position is unusually found at a very long distance from the ion. This far-coordinated water molecule possesses a degree of structure comparable with the other first shell molecules surrounding the ion at much shorter distances, and its presence gave us the unique opportunity to easily identify the geometry of the Sc(3+) coordination polyhedron. Despite very strong ion-water interactions, the Sc(3+) hydration shell is very labile, as the far-coordinated ligand allows first shell water molecules to easily exchange their positions both inside the solvation shell and with the rest of the solvent molecules.

    Scandium nitride (001) oriented layers have been grown on magnesium oxide (001) substrates by molecular beam epitaxy using a rf-plasma source and a scandium effusion cell. The Sc/N flux ratio is found to be critical in determining the structural, optical, and electronic properties of the grown epitaxial layers. A distinct transition occurs at the point where the Sc/N flux ratio equals 1, which defines the line between N-rich and Sc-rich growth. Under N-rich conditions, the growth is epitaxial, and the surface morphology is characterized by a densely packed array of square-shaped plateaus and four-faced pyramids with the terraces between steps being atomically smooth. The films are stoichiometric and transparent with a direct optical transition at 2.15 eV. Under Sc-rich conditions, the growth is also epitaxial, but the morphology is dominated by spiral growth mounds. The morphology change is consistent with increased surface diffusion due to a Sc-rich surface. Excess Sc leads to understoichiometric layers with N vacancies which act as donors. The increased carrier density results in an optical reflection edge at 1 eV, absorption below the 2.15 eV band gap, and a drop in electrical resistivity. {copyright} 2001 American Institute of Physics.

  5. State of the art of multicell SC cavities and perspectives

    Peter Kneisel

    2002-08-01

    Superconducting cavity technology has made major progresses in the last decade with the introduction of high purity niobium on an industrial scale and, at the same time, by an improved understanding of the limiting processes in cavity performance, such as multipacting, field emission loading and thermal break-down. Multicell niobium cavities for beta = 1 particle acceleration, e.g. for the TESLA project, are routinely exceeding gradients of Eacc = 20 MV/m after the application of surface preparation techniques such as buffered chemical polishing or electropolishing, high pressure ultrapure water rinsing, UHV heat treatment and clean room assembly. The successes of the technology for beta = 1 accelerators has triggered a whole set of possible future applications for beta < 1 particle acceleration such as spallation neutron sources (SNS, ESS), transmutation of nuclear waste (TRASCO, ASH) or rare isotopes (RIA). The most advanced of these projects is SNS now under construction at Oak Ridge National Laboratory. This paper will review the technical solutions adopted to advance SRF technology and their impact on cavity performance, based on the SNS prototyping efforts. 2K at these high gradients are no longer out of reach. For the accelerator builder the challenge remains to come up with a good and reasonable design, which takes into account the status of the technology and does not over-estimate the achievable cavity performances in a large assembly such as, e.g., a multi-cavity cryo-module. In the following the criteria for multi-cell sc cavity design are reviewed and it is attempted to give a snapshot of the present status of multi-cell cavity performances.

  6. Conceptual Design of the TPF-O SC Bus

    Purves, Lloyd R.

    2007-01-01

    One option under current study for the Terrestrial Planet Finder-Occulter (TPF-O) observatory shares some key features of the Hubble Space Telescope (HST). Both are space telescopes with a primary mirror aperture of around 2.4 meters and designed to observe in the visible to near infrared range of wavelengths, with the major difference in science capability being that TPF-O has an areal FOV on the order of 100 times larger than that of HST. This larger FOV, whose science camera is also expected to provide fine guidance, and other mission differences, mean that most TPF-O SC bus subsystems will have very different requirements than those of HST. Unlike HST in LEO, TPF-O is designed to operate in an orbit around the Sun-Earth lagrange 2 (SEL2) point. The longer communications range to SEL2 and the large FOV require much higher performance data processing and communications than HST. Maintaining a SEL2 orbit requires TPF-O, unlike HST, to have a propulsion system. TPF-O will have a specialized tracking system that allows the formation flying occulter to maintain its required position. However, despite these additional features, the velocity required for reaching SEL2 and the limited capabilities of affordable launch vehicles require TPF-O to have a compact and low-mass design relative to HST. Finally, TPF-O may utilize a modular design to reduce development cost and, if it required, allow servicing using approaches different from those of HST.

    The population of Winnebago County in 1918 was approximately 62,000 residents. It consisted of towns supporting diverse manufacturers surrounded by farming country. For this study, records were revisited, and 1918 to 1920 influenza survivors were interviewed. A pharmacological investigation encompassing the various influenza treatments used in Wisconsin from 1918 to 1920 was documented. In 1918, over 180 individuals perished from influenza, and over 2000 cases were reported in Winnebago County, Wisconsin. Influenza returned in 1920, which some researchers refer to as the “fourth wave,” claiming nearly 50 lives in Winnebago County, Wisconsin. This study also documents the 1920 influenza wave.

    A search of active deflation basins near Jal, Lea County, New Mexico resulted in the discovery of two meteorites, Lea County 001 and 002. Lea County 001 has mean olivine and low-Ca pyroxene compositions of Fa(19) and Fs(17), respectively. These and all other mineralogical and petrological data collected indicate a classification of H5 for this stone. Lea County 002 has mean olivine and low-Ca pyroxene compositions of Fa(2) and Fs(4), and is unequilibrated. Although it is mineralogically most similar to Kakangari and chondritic clasts within Cumberland Falls, the high modal amount of forsterite makes Lea County a unique type 3 chondrite. Oxygen isotope data for Lea County 002 fall on an 0-16-mixing line through those of the enstatite meteorites and IAB irons, a feature shared by Kakangari. 28 refs.

    The time-differential γ-γ perturbed-angular-correlation (TDPAC) technique using T44i→S44c tracers was applied to study the nuclear quadrupole interaction of the first excited I=1 state of S44c in the cubic bixbyite structure of scandium sesquioxide (Sc2O3) . In addition, ab initio calculations of electronic and structural properties and hyperfine parameters at the cationic sites of the Sc2O3 structure were performed using the full-potential augmented plane wave plus local-orbital (APW+lo) method. The accuracy of the calculations and the excellent agreement of the predicted electric-field-gradient (EFG) tensors and the structural properties (lattice parameters, internal positions) with the experimental results enable us to identify the observed hyperfine interactions and to infer the EFG sign that cannot be measured in conventional TDPAC experiments. Additionally, the APW+lo calculations show that the EFG at Sc sites is originated in the population of Sc3p states and give an explanation for the preferential occupation of the asymmetric cationic site C of the structure by the T44i doping impurities. Finally, the validity of the ionic model, usually used to describe the EFG at native cation sites, is discussed.

    The germanides ScTGe (T = Co, Ni, Cu, Ru, Rh, Pd, Ag, Ir, Pt, Au) were obtained in X-ray pure form by arc-melting of the elements. The structures of the members with T = Co, Ni, Cu, Rh, Pd, Ag, Ir, and Pt were refined on the basis of single crystal X-ray diffractometer data. The germanides with T = Cu, Ru, Pd, Ag crystallize with the hexagonal ZrNiAl type structure, space group P 6 bar 2m and those with T = Co, Ni, Rh, Ir, Pt adopt the orthorhombic TiNiSi type. ScAuGe is isotypic with NdPtSb. All germanides exhibit single scandium sites. A simple systematization of the structure type according to the valence electron concentration is not possible. The 45Sc solid state NMR parameters (Knight shifts and nuclear electric quadrupole coupling constants) of those members crystallizing in the TiNiSi structure show systematic trends as a function of valence electron concentration number. Furthermore, within each T-group the Knight shift decreases with increasing atomic number; this correlation also includes previously published results on the isotypic silicide family. The 45Sc quadrupolar interaction tensor components are generally well-reproduced by quantum mechanical electric field gradient calculations using the WIEN2k code.

    We investigate the synthesis of a thallium scandate, TlScO3, under high-pressure (6-7.7 GPa) and high-temperature (1373-1773 K) conditions. At 6 GPa, a LiNbO3-type phase appears in a narrow temperature range and in mixtures with other phases. At 7.7 GPa and 1673 K, a new LiNbO3-type oxide is found with a composition of (Tl(1-x)Sc(x))ScO3 and x ≈ 0.26 as determined by structural analysis from X-ray powder diffraction data. It crystallizes in space group R3c (No. 161) with lattice parameters of a = 5.50283(7) Å and c = 14.4606(2) Å. It is stable at least up to 800 K at ambient pressure. The point-charge model gives an electric polarization of 60 μC/cm(2). First-principles calculations show that centrosymmetric ilmenite-type and polar LiNbO3-type structures of stoichiometric TlScO3 have almost the same lowest energy, and the next stable structure is a GdFeO3-type perovskite structure.

  14. ScP constraints on ultralow-velocity zone parameters using Viterbi Sparse Spike Detection

    NASA Astrophysics Data System (ADS)

    Thorne, M. S.; Brown, S. P.; Rost, S.

    2012-12-01

    We present a new algorithm for estimating seismic travel times and amplitudes for individual arrivals comprising band-limited seismic traces. The method uses the Viterbi algorithm to determine the most likely sparse spike train to explain observed seismic data given a wavelet estimate. Compared to other deconvolution methods, this algorithm is relatively insensitive to errors in the estimated wavelet and requires no assumptions regarding the distribution of travel times and amplitudes, or the stationarity of the band-limited wavelet. A salient feature of the core mantle boundary (CMB) region is the existence of ultra-low velocity zones (ULVZs). ULVZ physical parameters have been reported to have S-wave velocity reductions (δVS) as large as 45% (with respect to the Preliminary Reference Earth Model), P-wave velocity reductions (δVP) as large as 20%, density increases (δρ) of up to 10%, and thicknesses of up to 40 km. Nevertheless, strong tradeoffs typically exist in the model space and many of these parameters are uncertain. The seismic phase ScP is of utmost importance in studying ULVZs as it is sensitive to all elastic parameters. The reason ScP is well-suited for ULVZ studies is because of the existence of two pre-cursors and one post-cursor that are predicted if the ScP wave field interacts with a ULVZ. The value of ScP in determining the relatively unknown S-wave velocity reduction is in that the amplitude of the SdP and ScSP arrivals are most strongly dependent on S-wave velocity reduction. However, precise determination of the amplitudes of the ScSP post-cursor is complicated by the presence of the ScP coda, which is most pronounced in the short period data. Additionally, both of the precursor arrivals are predicted to have relatively low amplitudes with respect to ScP and the majority of studies have only been capable of identifying a single pre-cursor. In this study we examine ScP waveforms interacting with a ULVZ in the southwestern Pacific Ocean

  15. SU-E-T-293: Simplifying Assumption for Determining Sc and Sp

    SciTech Connect

    Purpose: Scp(mlc,jaw) is a two-dimensional function of collimator field size and effective field size. Conventionally, Scp(mlc,jaw) is treated as separable into components Sc(jaw) and Sp(mlc). Scp(mlc=jaw) is measured in phantom and Sc(jaw) is measured in air with Sp=Scp/Sc. Ideally, Sc and Sp would be able to predict measured values of Scp(mlc,jaw) for all combinations of mlc and jaw. However, ideal Sc and Sp functions do not exist and a measured two-dimensional Scp dataset cannot be decomposed into a unique pair of one-dimensional functions.If the output functions Sc(jaw) and Sp(mlc) were equal to each other and thus each equal to Scp(mlc=jaw){sup 0.5}, this condition would lead to a simpler measurement process by eliminating the need for in-air measurements. Without the distorting effect of the buildup-cap, small-field measurement would be limited only by the dimensions of the detector and would thus be improved by this simplification of the output functions. The goal of the present study is to evaluate an assumption that Sc=Sp. Methods: For a 6 MV x-ray beam, Sc and Sp were determined both by the conventional method and as Scp(mlc=jaw){sup 0.5}. Square field benchmark values of Scp(mlc,jaw) were then measured across the range from 2×2 to 29×29. Both Sc and Sp functions were then evaluated as to their ability to predict these measurements. Results: Both methods produced qualitatively similar results with <4% error for all cases and >3% error in 1 case. The conventional method produced 2 cases with >2% error, while the squareroot method produced only 1 such case. Conclusion: Though it would need to be validated for any specific beam to which it might be applied, under the conditions studied, the simplifying assumption that Sc = Sp is justified.

    Three-dimensional geometry of the upper boundary of the Pacific plate subducting beneath Hokkaido, Japan, was obtained using the ScSp phase: the phase converted from ScS (S wave reflected at the core•mantle boundary) to P wave at the plate boundary. Taking the advantage of a dense seismic network, "Hi-net", recently deployed across the Japanese islands, we applied several seismic array analyses to the recorded waveform data for a large nearby deep earthquake, in order to enhance very weak ScSp signals in the original records. At first, we set up five blocks for the region in plate dip directions. After aligning the travel times of ScS and stacking seismograms among stations in a given sub-block perpendicular to each dip direction, we searched for the optimal plate model (i.e., two-dimensional geometry of the upper boundary) for each block. The model was parameterized by seven depth grids, and seismograms were stacked based on the travel time of ScSp as a time lag of each sub-block, so that the optimal model would yield the maximum spectral energy of ScSp after stacking. This model parameter search was conducted, using ray tracings of ScSp with a reference velocity model and a non-linear inversion scheme (Neighbourhood Algorithm). The optimal model of each block was combined each other by cubic spline interpolation, in order to construct an overall three-dimensional geometry of the upper boundary of the plate. Next, we performed the frequency•wavenumber (f•k) spectral analysis to refine the above result. Assuming each station as a reference point, we made beam output from records of its adjacent stations as a function of wavenumber vector (kx,ky) and frequency. The peak of its power spectrum was considered to represent the wavenumber vector of ScSp, that is, azimuth of arrival and slowness, so that we can estimate the position and depth of the corresponding ScS•ScSp conversion. In the frequency range from 0.5 to 1.5 Hz, we could estimate the conversion

    In February 1983, the US Department of Energy (DOE) identified a location in Deaf Smith County, Texas, as one of the nine potentially acceptable sites for mined geologic repository for spent nuclear fuel and high-level radioactive waste. To determine their suitability, the Deaf Smith County site and eight other potentially acceptable sites have been evaluated in accordance with the DOE's General Guidelines for the Recommendation of Sites for the Nuclear Waste Repositories. The Deaf Smith County site is in the Permian Basin, which is one of five distinct geohydrologic settings considered for the first repository. On the basis of the evaluations reported in this EA, the DOE has found that the Deaf Smith County site is not disqualified under the guidelines.

    Before deciding on the appropriate county recycling facility for their communities, waste management officials from Medina County, Ohio, spent three years researching their options. First and foremost, they wanted to generate a recycling amount that would at least double House Bill 592's requirements which calls for a 25% reduction in reliance on landfill space. After issuing a request for proposals, the county opted for a central processing facility (CPF)--which was designed, built, and is now operated by Norton Environmental (Independence, Ohio). Currently, the CPF extracts and processes recyclables, materials for refuse-derived fuel (RDF), and compostables from a mixed solid waste stream. After operating for just over one year, the facility, which is located in Seville, Ohio, is well on its way to achieving its goal of recovering two-thirds of the county's incoming mixed solid waste stream, and waste management officials there couldn't be happier with their selection.

    Permitting is a crucial step in the development cycle of a wind project and permits affect the timing, cost, location, feasibility, layout, and impacts of wind projects. Counties often have the lead responsibility for permitting yet few have appropriate siting regulations for wind projects. A model ordinance allows a county to quickly adopt appropriate permitting procedures. The model county wind ordinance developed for use by northwest states is generally applicable across the country and counties seeking to adopt siting or zoning regulations for wind will find it a good starting place. The model includes permitting procedures for wind measurement devices and two types of wind systems. Both discretionary and nondiscretionary standards apply to wind systems and a conditional use permit would be issued. The standards, criteria, conditions for approval, and process procedures are defined for each. Adaptation examples for the four northwest states are provided along with a model Wind Resource Overlay Zone.

    Leukemic cancer stem cells (LSCs), as a unique cell population in acute myeloid leukemia (AML) marked by CD123 overexpression, are thought to play a key role in relapsed AML after chemotherapy. Thus, CD123 is considered as a particularly important target candidate for antibody-derived diagnosis and therapy. In the present work, we constructed an immunized murine antibody phage display library and isolated the functional anti-CD123 Single-chain fragment variable (scFv) clones. We also introduced fusing variable light (VL) and heavy (VH) chains with a new 18-amino acid residue linker as an alternative to conventional linkers. CD123-specific phage clones were progressively enriched through 4 rounds of biopanning, validated by phage ELISA, and anti-CD123 scFv clones with highest affinity were produced in Escherichia coli. The expression and purification of soluble scFv were verified by Western blot, and the results were indicative of the functionality of our proposed linker. The purified scFv specifically recognized CD123 by ELISA and flow cytometry, without any cross-reactivity with other related cell markers. Affinity of anti-CD123 scFv was measured to be 6.9 × 10(-7) M, using the competitive ELISA. Our work, therefore, provides a framework for future studies involving biological functions and applications of our anti-CD123 scFv. It also reveals the feasibility of high throughput methods to isolate biomarker-specific scFvs. PMID:26749295

    In the case of solvent selection, supersolubility is an index for improving crystallization behavior. However, supersolubility is affected by kinetic factors such as the cooling rate. An index for suitable solvent selection is needed. The supersaturation ratio (S) is one of the operation design indices of controlling crystallization behavior such as supersolubility. The S at 298 K (S298) of the pharmaceutical compounds theophylline, noscapine, clotrimazole, indomethacin, carbamazepine, naproxene and tolbutamide were measured in ethanol using a polythermal method. If the compound had a large lnS298, the cooling rate strongly affected the temperature of the cloud point in the cooling crystallization method. In order to estimate the crystallization behavior without the cooling rate effect, the critical supersaturation ratio (Sc) was proposed. Sc at 298 K (Sc298) was calculated from dissolution/cloud points at 0 K/min extrapolated from that of several heating/cooling rates to remove the kinetic effects on S. The lnSc298 values of theophylline, noscapine and clotrimazole were estimated in acetonitrile, methyl ethyl ketone, tetrahydrofuran, ethyl acetate, methanol, ethanol and isopropanol. The lnSc298 value of clotrimazole was the largest in all solvents. The results showed that lnSc298 was a simple index which could be used to evaluate the crystallization behavior resulting from the interaction between the solvent and the compound. In conclusion, the proposed lnSc298 should be useful for comparing the difficulty of crystallization which indicates how we should obtain desired crystals within a certain finite time period for development API in the manufacturing field without considering the effect of the heating/cooling rate.

    We surveyed the flora of Oktibbeha County, Mississippi, U.S.A., from February 1994 to 1996. Occupying 118 square kilometers in east-central Mississippi, Oktibbeha County lies among 3 physiographic regions that include, from west to east, Interior Flatwoods, Pontotoc Ridge, and Black Prairie. Accordingly, the county harbors a diverse flora. Based on field work, as well as an extensive review of published literature and herbarium records at IBE and MISSA, we recorded a total of 1,148 taxa (1,125 species, 7 hybrids, 16 infraspecific taxa) belonging to 514 genera in 160 families, over 85% of all taxa documented were native. Compared to 3 other counties in east-central Mississippi, Oktibbeha County has the second largest recorded flora. The number of state-listed (endangered, threatened, or of special concern) taxa (67) documented in this survey far exceeds that reported from any other county in the region. Three introduced species, Ilex cornuta Lindl. & Paxton, Mahonia bealei (Fortune) Carrie??re, and Nandina domestica Thunb., are reported in a naturalized state for the first time from Mississippi. We also describe 16 different plant communities belonging to 5 broad habitat categories: bottomland forests, upland forests and prairies, aquatic habitats, seepage areas, and human-influenced habitats. A detailed description of the vegetation associated with each of these communities is provided.

    The Maricopa County Geothermal Development Plan evaluated the market potential for utilizing geothermal energy. The study identified six potential geothermal resource areas with temperatures less than 100{sup 0}C (212{sup 0}F) and in addition, four suspected intermediate temperature areas (90{sup 0} to 150{sup 0}C, 194{sup 0} to 300{sup 0}F). Geothermal resources are found to occur in and near the Phoenix metropolitan area where average population growth rates of two to three percent per year are expected over the next 40 years. Rapid growth in the manufacturing, trade and service sectors of the regional economy provides opportunities for the direct utilization of geothermal energy. A regional energy use analysis is included containing energy use and price projections. Water supplies are found to be adequate to support this growth, though agricultural water use is expected to diminish. The study also contains a detailed section matching geothermal resources to potential users. Two comparative analyses providing economic details for space heating projects are incorporated.

    Single chain variable fragment (scFv) antibody libraries are widely used for developing novel bioaffinity reagents, although Fab or IgG molecules are the preferred antibody formats in many final applications. Therefore, rapid conversion methods for combining multiple DNA fragments are needed to attach constant domains to the scFv derived variable domains. In this study we describe a fast and easy cloning method for the conversion of single framework scFv fragments to Fab fragments using type IIS restriction enzymes. All cloning steps excluding plating of the Fab transformants can be done in 96 well plates and the procedure can be completed in one working day. The concept was tested by converting 69 scFv clones into Fab format on 96 well plates, which resulted in 93% success rate. The method is particularly useful as a high-throughput tool for the conversion of the chosen scFv clones into Fab molecules in order to analyze them as early as possible, as the conversion can significantly affect the binding properties of the chosen clones.

    The adsorption properties of a single CO molecule on Sc(n) (n=2-13) clusters are studied by means of a density functional theory with the generalized gradient approximation. Two adsorption patterns are identified. Pattern a (n=3, 4, 6, 8, 11, and 12), CO binds to hollow site while Pattern b (n=5, 7, 9, 10, and 13), CO binds to bridge site accompanied by significantly lengthening of the Sc-Sc bond. The adsorption energy exhibits clear size-dependent variation and odd-even oscillation for n<10 and reach the peak at n=5, 7, and 9, implying their high chemical reactivity. Similar variations are noted in C-O bond length, vibrational frequency, and charge transferred between CO and the clusters. This can be understood in light of the adsorption pattern, the atomic motif, and the relative stability of the bare Sc clusters. Compared with the free Sc clusters, the magnetic nature remains upon adsorption except n=2, 4, 12, and 13. Particularly, the moments of n=13 reduce significantly from 19 to 5 micro(B), implying the adsorption plays an attenuation influence on the magnetism of the cluster. PMID:18554021

    Variations of Vickers hardness were observed in Al-Mg-Mn alloy and Al-Mg-Mn-Sc-Zr alloy at different ageing times, ranging from a peak value of 81.2 HV at 54 ks down to 67.4 HV at 360 ks, below the initial hardness value, 71.8 HV at 0 ks for the case of Al-Mg-Mn-Sc-Zr alloy. Microstructures of samples at each ageing stage were examined carefully by transmission electron microscopes (TEMs) both in two-dimensions and three-dimensions. The presence of different types, densities, and sizes of particles were observed dispersed spherical Al3Sc1-xZrx and also block-shaped Al3Sc precipitates growing along <100>Al with facets {100} and {110} of the precipitates. TEM analysis both in two-dimensions and three-dimensions, performed on various samples, confirmed the direct correlation between the hardness and the density of Al3Sc. PMID:26748212

    Integration host factor (IHF), a multifunctional protein of E. coli, normally is required for the replication of plasmid pSC101. T. T. Stenzel, P. Patel, and D. Bastia (Cell 49:709-717, 1987) have reported that IHF binds to a DNA locus near the pSC101 replication origin and enhances a static bend present in this region; mutation of the IHF binding site affects the plasmid's ability to replicate. We report here studies indicating that the requirement for IHF binding near the pSC101 replication origin is circumvented partially or completely by (i) mutation of the plasmid-encoded repA (replicase) gene or the chromosomally encoded topA gene, (ii) the presence on the plasmid of the pSC101 partition (par) locus, or (iii) replacement of the par locus by a strong transcriptional promoter. With the exception of the repA mutation, the factors that substitute for a functional origin region IHF binding site are known to alter plasmid topology by increasing negative DNA supercoiling, as does IHF itself. These results are consistent with the proposal that IHF binding near the pSC101 replication origin promotes plasmid replication by inducing a conformational change leading to formation of a repA-dependent DNA-protein complex. A variety of IHF-independent mechanisms can facilitate formation of the putative replication-initiation complex. PMID:1310092
