    Alkyne insertion into four-membered carbocyclic rings was achieved through rhodium(I)-catalyzed C-C bond cleavage. The reaction of (2-pyridylmethylene)cyclobutenes proceeded via C-C oxidative addition, and that of cyclobutenols involved β-carbon elimination. In both the cases, multiply substituted benzenes were obtained through the aromatization of the initially formed 1,4-cyclohexadienes.

    Preparing healthy community members with timely communications prior to engaging them in a request to donate biospecimens promises to improve the experience of biobanking participation. To this end, a qualitative study was conducted to assess community member knowledge, attitudes, beliefs, and informational needs about cancer-related biospecimen collection in a large metropolitan area in southwest Florida. The study utilized purposive sampling techniques to recruit a total of 95 participants to participate in 12 focus groups, segmented by race/ethnicity and language preference (mixed race, African American only, and Spanish speaking) and age (18–29, 30–54, and 55 and older). Focus group interviews were analyzed using content analysis to identify emergent themes. Overall, participants in the 30 years and older groups were favorable toward participating in biobanking if their concerns were addressed, such as confidentiality and consent issues, in contrast to participants aged 18–29 who were more skeptical. For all participants, the desire to participate in research that seeks new cancer treatments outweighed mistrust. Moreover, many cited the potential scientific benefit for future generations as a primary motivator. Finally, in some groups a therapeutic misconception was expressed, where participants expressed a willingness to forego confidentiality of their health status in exchange for therapeutic benefit. This study contributes to the literature on community perceptions of the benefits and barriers of biobanking and adds to the development of meaningful education communication priming tools to advance understandings about biobanking.

    The Oso Ridge Member (new), at the base of the Abo Formation, nonconformably overlies Proterozoic rocks. The member consists of some 9m of conglomerate and arkose composed principally of fragments of the underlying Proterozoic metamorphic rocks; thin, fossiliferous limestone lenses are interbedded with the arkose. Biota from the lenses include a phylloid alga, foraminifers, conodonts, brachiopods, and molluscs. The age of the Oso Ridge Member is Virgilian Late Pennsylvanian) to Wolfcampian (Early Permian). -from Authors

    The Lower Permian Schoolhouse Member of the Maroon Formation forms a partly exhumed petroleum reservoir in the Eagle basin of northwestern Colorado. The Schoolhouse consists mainly of yellowish gray to gray, low-angle to parallel bedded, very fine to fine-grained sandstone of eolian sand-sheet origin; interbedded fluvial deposits are present in most sections. Geological and geochemical data suggest that Schoolhouse Member oils have upper Paleozoic sources, including the intrabasinal Belden Formation. Late Paleozoic faults have served as local conduits for vertical petroleum migration. Large-scale (>200 km) lateral migration from sources in the Permian Phosphoria Formation is also possible but less likely. Belden oil was generated and migrated before about 75 Ma. Subsequently, the Schoolhouse Member reservoir was uplifted, then partly exhumed on the monoclinal flank of the Laramide (latest Cretaceous-Paleogene) White River uplift. -from Authors

    2012-05-01

    Member 1 of the Swartkrans Formation is comprised of two sedimentary infills, the Lower Bank (LB) and the Hanging Remnant (HR). Together, the LB and HR preserve fossils of early Homo and Paranthropus robustus, Earlier Stone Age lithic artifacts, purported bone digging tools and butchered animal bones. Collectively, this evidence was the first to establish the co-existence of two early Pleistocene hominid species and also led to inferences of plant root harvesting and meat-eating by one or both of those species. P. robustus is the more abundant of the two hominids at Swartrkrans, represented in Member 1 by hundreds of fossils that derive from at least 99 individuals. Thus, Swartkrans Member 1 stands as the world's single largest repository of that extinct species. Here we add to the Member 1 sample of hominid fossils with descriptions of 14 newly discovered specimens.

    The authors used survey data from 127 professional-level employees working in 8 industries to assess the effects of respondent's trusting stance and (a) the trustee's organization membership (internal or external), (b) the hierarchical relationship (supervisor or peer), and (c) the gender of the trustee, on initial trust level for a new project team member. The authors found that trusting stance was positively related to initial trust level. The authors also found an interaction effect between respondent gender and trustee gender on initial trust. Specifically, male initial trust level was higher for a new male team member and lower for a new female team member. The present study provided additional understanding of the formation of initial trust levels and its importance for team functioning.

    Hatters Pond field is in east-central Mobile County in southwestern Alabama and it produces from both the Norphlet and Smackover formations. The structural trap involves salt movement along the west side of the Mobile Fault System that resulted in a faulted salt anticline. The Norphlet Formation of southwestern Alabama consists of red to gray siltstone and pinkish to gray sandstone with conglomerate layers. Three facies have been distinguished within the Norphlet Formation: a lower shale, a red siltstone sequence, and an upper quartzose unit. The thickness of the formation ranges from a feather edge to more than 800 ft (234.8 m) in southwestern Alabama. The Upper Jurassic Denkman Sandstone Member of the Norphlet Formation at Hatters Pond field is a medium- to fine-grained, well-sorted arkosic sandstone between the underlying Norphlet redbed lithofacies and the carbonates of the overlying Smackover Formation. Here, the Denkman Member can be subdivided into a massive upper unit and a low- to high-angle cross-stratified lower unit. The sandstones are quartz-rich with a high percentage of feldspars. The majority of the feldspar grains observed are potassium feldspar. Microcline is usually less altered when compared with other types of feldspar grains. The major types of feldspar replacement include illitization, hematitization, dolomitization, chloritization, calcitization, vacuolization, and anhydritization. Carbonate replacement of feldspars is very abundant, mostly by ferroan dolomite. Rock fragments are not abundant in the Denkman Member, although there is good evidence of a metamorphic/volcanic source area. The sandstones are cemented by dolomite, calcite, anhydrite, and quartz and feldspar overgrowths. The lower Denkman unit is slightly more porous than the upper Denkman unit. The pore-lining authigenic clay, illite, greatly reduces permeability and porosity in these sandstones.

    During the last decade, the number of different types of enzymes applicable for organic synthesis as biocatalysts has significantly increased. Consequently, the spectrum of reactions has significantly expanded also for cyclisations. This review highlights heterologously expressable biocatalysts transforming non-natural substrates for the formation of three- to six-membered carbo- and heterocycles, excluding terpene cyclases as well as SAM-dependent enzymes. The review focuses on the non-natural substrate scope and the mechanism of the selected enzymes.

    The lower part of the Buckner anhydrite member of the Haynesville Formation (Upper Jurassic) was deposited as shallowing upward cycles of subaqueous to subaerial deposits on the north flank of the Wiggins arch in northeastern Mobile County, Alabama. The unit studied conformably overlies the Smackover Formation and is generally evaporite dominated. The Buckner anhydrite averages about 35 m (115 ft) thick and has been buried to depths of 5.5 km (> 18,000 ft). Despite this deep burial, the unit has suffered little deformation since alteration of gypsum to anhydrite.

    2015-01-01

    This paper proposes a Multiple Leader Candidate (MLC) structure and a Competitive Position Allocation (CPA) algorithm which can be applicable for various applications including environmental sensing. Unlike previous formation structures such as virtual-leader and actual-leader structures with position allocation including a rigid allocation and an optimization based allocation, the formation employing the proposed MLC structure and CPA algorithm is robust against the fault (or disappearance) of the member robots and reduces the entire cost. In the MLC structure, a leader of the entire system is chosen among leader candidate robots. The CPA algorithm is the decentralized position allocation algorithm that assigns the robots to the vertex of the formation via the competition of the adjacent robots. The numerical simulations and experimental results are included to show the feasibility and the performance of the multiple robot system employing the proposed MLC structure and the CPA algorithm.

  14. Late Miocene fanglomerates in lower member of Starlight Formation, northern Portneuf Range, Idaho

    1987-08-01

    The lower member of the late Miocene Starlight Formation in the northern Portneuf Range, southeastern Idaho, represents sedimentation influenced by both Basin-and Range faulting and eastern Snake River plain (SRP) volcanism. The lower Starlight contains at least 610 m of fanglomerates and thin, interbedded basalt flows. The formations lower half is interpreted as medial alluvial fan facies and consists of coarse tuffaceous heterolithologic conglomerate lenses and sheets, and interbedded immature tuffaceous pebbly lithic arenites. The fine-grained upper half of the member is interpreted as distal-fan facies. The sandy deposits of the distal facies are cut by numerous gravel-filled channels. On the basis of clast assemblages and preservation of fragile rhyolite tuff grains that could not survive long transport distances, these deposits were likely derived from nearby sources. In addition, paleocurrent data indicate a general westerly transport direction. Individual drainage systems apparently controlled sedimentation, as indicated by different clast assemblages at various locations. The dominant clast type in The Cove, southwest of the Blackfoot River, is Eocene andesitic volcanics. In outcrops 20 km south, Paleozoic and lower Mesozoic sedimentary clasts predominate. Chert pebble conglomerate clasts, found only in southern exposures, may have been derived from distant eastern outcrops of Cretaceous conglomerates. Alluvial fan deposits in the lower member of the Starlight Formation developed as a response to early Basin-and-Range uplift. However, they were also influenced by eastern SRP volcanism, as indicated by the presence of tuffaceous sediments and basaltic lava flows. The fan deposits likely originated from a nearby eastern source that is now covered by Tertiary volcanics of the Blackfoot laval field.

    The Molina Member of the Wasatch Formation has been cored in order to assess the presence/absence and character of microbial communities in the deep subsurface. Geological study of the Molina Member was undertaken in support of the microbiological tasks of this project, for the purposes of characterizing the host strata and of assessing the potential for post-depositional introduction of microbes into the strata. The Molina Member comprises a sandy fluvial unit within a formation dominated by mudstones. Sandy to conglomeratic deposits of braided and meandering fluvial systems are present on the western and eastern margins of the basin respectively, although the physical and temporal equivalence of these systems cannot be proven. Distal braided facies of planar-horizontal bedded sandstones are recognized on the western margin of the basin. Natural fractures are present in all Molina sandstones, commonly as apparent shear pairs. Core from the 1-M-18 well contains natural fractures similar to those found in outcrops, and has sedimentological affinities to the meandering systems of the eastern margin of the basin. The hydrologic framework of the Molina, and thus any potential post-depositional introduction of microbes into the formation, should have been controlled by approximately east-west flow through the natural fracture system, the geometries and extent of the sandstones in which the fractures occur, and hydraulic gradient. Migration to the well site, from outcropping recharge areas at the edge of the basin, could have started as early as 40 million years ago if the cored strata are connected to the eastern sedimentary system.

    The Upper Jurassic Morrison Formation has yielded one of the richest floras of the so-called transitional conifers'' of the Middle Mesozoic. Recently, a silicified axis of one of these conifers was collected from the Salt Wash member in essentially the same horizon as a previously reported partial Stegosaurus skeleton. In addition, two other axes of conifers were collected in the same immediate vicinity. Paleoecological considerations are extrapolated from the coniferous flora, vertebrate fauna and associated lithologies. Techniques of paleodendrology and relationships of extant/extinct environments are compared. The paleoclimatic conditions of the transitional conifers and associated dinosaurian fossils are postulated.

    Paleosols and lacustrine sediments of the Yellow Cat Member (YCM), Cedar Mountain Formation (CMF), Eastern Utah were collected at the "Lake Madsen" (a dominantly lacustrine section) and Doelling's Bowl (a mixed lacustrine/ palustrine/ paleosol section) and analyzed for bulk organic carbon isotopes (δ13Corg) . The YCM is thought to span the Barremian to Aptian based on dinosaur faunal assemblages. Correlation with distinct carbon isotope excursions (CIE) specifically those associated with the Selli Event or OAE 1a would allow insight into the response of terrestrial ecosystems to C-cycle perturbations during the Aptian, and may improve chronostratigraphy. Lake Madsen data ranges between a minimum of -28.5‰ and a maximum of -21.4‰ with an average of ~ -25‰ and shows a stepped negative isotope excursion of -3‰., with three distinct negative steps starting ~ 7.5 m above the Jurassic Morrison Formation and an intervening large positive excursion ~ 4.5 m from the base of the Poison Strip Sandstone (~119Ma) Member of the CMF. Doelling's Bowl data spans a longer vertical distance and ranges from a minimum of -29.0‰ to a maximum of -25.7‰, averages -27.7‰ and is somewhat cyclic in nature. δ13Corg chemostratigraphic profile for Doelling's Bowl poorly correlates to the Lake Madsen section, likely due to recycling of organic C and wet/dry cycles of the palustrine environment. Correlation of the Lake Madsen section to marine δ13CCO3 curve from Cismon Valley of the southern Alps indicates the lower Aptian C-isotope excursions C1 to C6, with the distinctive C3 negative CIE occur at the top of the Yellow Cat Member, therefore documenting a terrestrial manifestation of the CIE associated with OAE1a - Selli Event. This suggests the age of the majority of the Yellow Cat Member is Barremian to lower Aptian and the Barremian-Aptian boundary occurs at the top of the Member ~ 25cm below the base of the Poison Strip Sandstone.

    Presence of sandstone streaks in Sidri Member within Belayim Formation that lies between two productive zones; Kareem Formation and Hammam Faraun Member, was the main reason to perform this study. It may represent a good hydrocarbon reservoir and will be added to the Egyptian oil production in some wells of Badri field. This Member has high resistivity signature on Electric-logs responses which attracted the attention to investigate its occurrence in the field, to delineate its distribution all-over the area, to evaluate the petrographic and petrophysical characteristics and to evaluate its productivity. Petrographic and petrophysical analyses of these sand zones were undertaken using thin section samples. The electric logs and subsurface geologic data was used to evaluate the main reservoir characteristics of the Sidri sandstone such as lithology, cementation, shale volume, porosity (Φ), effective porosity (Φ eff), estimated permeability (K), fluid saturation, fluid type and Net pay thickness. This study revealed that, Sidri sandstone facies was classified into two mainly sandy facies; blocky sandy facies which located at the northern part of the field and streaky sandy facies at the southern area of the field. These two facies are separated by shaley facies. Some wells were studied to represent the two sandy facies in Sidri Member and these sand intervals have not been tested yet. These sands consist of quartz grains with grey and pink feldspars as accessory minerals, with siliceous and calcareous cementation, with good porosity. Petrophysical evaluation of this sand unit indicated that it is hydrocarbon bearing formation in three wells and water bearing one in other wells. Electrical logs analysis (Resistivity, Density-Neutron, Sonic and Gamma-Ray) revealed that The volume of shale in this sandstone, the effective porosity, the water saturation, the estimated permeability, the hydrocarbon saturation, and the net-pay thickness are varying from 9 to 13%, 19

    The Sheepbed member of the Yellowknife Bay formation in Gale crater contains millimeter-scale nodules that represent an array of morphologies unlike those previously observed in sedimentary deposits on Mars. Three types of nodules have been identified in the Sheepbed member in order of decreasing abundance: solid nodules, hollow nodules, and filled nodules, a variant of hollow nodules whose voids have been filled with sulfate minerals. This study uses Mast Camera (Mastcam) and Mars Hand Lens Imager (MAHLI) images from the Mars Science Laboratory Curiosity rover to determine the size, shape, and spatial distribution of the Sheepbed nodules. The Alpha Particle X-Ray Spectrometer (APXS) and ChemCam instruments provide geochemical data to help interpret nodule origins. Based on their physical characteristics, spatial distribution, and composition, the nodules are interpreted as concretions formed during early diagenesis. Several hypotheses are considered for hollow nodule formation including origins as primary or secondary voids. The occurrence of concretions interpreted in the Sheepbed mudstone and in several other sedimentary sequences on Mars suggests that active groundwater systems play an important role in the diagenesis of Martian sedimentary rocks. When concretions are formed during early diagenetic cementation, as interpreted for the Sheepbed nodules, they have the potential to create a taphonomic window favorable for the preservation of Martian organics.

    The Campanian Hajajah Limestone Member of the Aruma Formation was formed during two regressive episodes. Each of them formed of three depositional facies, from base to top: 1) intra-shelf basin facies, made up of fossiliferous green shale and mudstone with ostracods and badly preserved foraminifers. 2) fore-reef facies, consists of hard, massive, marly coralline limestone. The upper part is rich with low divers, badly to moderate preserved, solitary and colonial corals, and, 3) back reef and near-shore facies, consists of fossiliferous sandy dolomitized, bioturbated limestone with abundant reworked corals, bivalves, gastropods, and aggregate grains. On the basis of field observations, micro-and macrofossils and microfacies analysis, the Hajajah Limestone Member was deposited in distal marine settings below storm wave base in a low-energy environment changed upward to fore-reef framework in an open marine environment with moderate to high energy conditions and terminated with shallow marine facies with accumulation of skeletal grains by storms during regression.

    The outcrop of the upper Silurian Cobleskill and Akron members of the Rondout formation of New York State extends from Buffalo to E. Schoharie County and is continuous except where the units have been removed by pre-onondaga erosion. Strata included in the Cobleskill, Akron, and Chrysler members of the Rondout formation, underlying Williamsville member of the Bertie formation, and underlying Brayman Shale include several distinct Carbonate facies which have been identified by field characteristics, thin section petrography, insoluble residue analysis, and x-ray diffraction. Subfacies of the Cobleskill include subtidal biomicrites with stromatoporoid biostromes and intertidal fossiliferous micrites, whereas the Akron contains dolomitized analogs of these limestones. The overlying Chrysler is composed of supratidal, laminated, thinly bedded, finely crystalline dolostone. Careful lateral tracing of lithofacies, analysis of vertical lithofacies sequences, and study of key beds within the Cobleskill and Akron have resulted in recognition of the lateral equivalence of these 2 members. 32 references.

    This study, one in a series, reports bulk chemical composition of rock samples collected from a core, referred to as Measured Section J, drilled at a site that subsequently was developed into the Enoch Valley phosphate mine in southeastern Idaho. The core is continuous and cuts through the entire thickness of the Meade Peak Phosphatic Shale Member of the Phosphoria Formation. The steeply dipping Meade Peak extends from 182 to 495 feet below the ground surface, which is the greatest below-ground depth of rock that has been sampled to date. The core was drilled before the start of mining, and the rocks consequently have not been exposed to the atmosphere or surficial weathering processes or fractured as a result of mining as are the rocks from other described sections. Hence, this section of the Meade Peak in the core is the least altered section of this member sampled in this series of studies. The channel-sampled rocks from Section J form a set of contiguous intervals across the entire thickness of the Meade Peak. These channel samples characterize?in ascending order?the lower phosphate ore, interlayered middle waste shale, upper phosphate ore, and upper waste shale units of the member. The Section J channel-sample suite includes 3 composite samples of the uppermost 7 feet of the Grandeur Tongue of the Permian Park City Formation, a dolomitic unit that directly underlies the Meade Peak. It also includes an analysis of a 0.1 foot section of chert directly overlying the Meade Peak. The concentrations of the chemical elements in the channel samples are compared with those of Measured Sections Aand B that were obtained from the same mine. In addition to the channel samples, 85 rock samples were selected from the core to address specific geochemical questions that resulted from examination of the core. For example, several of these samples correspond to cored rock that had unusual concentrations of various elements that were determined using a hand-held, x

    Ongoing paleomagnetic analysis of the Plio-Pleistocene Palm Spring Formation of the Mecca Hills, CA provides insight into the development and sedimentation of transtensional basins in the San Andreas fault zone. Samples have a mixture of demagnetization behavior- roughly half the samples and sites have well-defined magnetization components that allow for best-fit lines to be identified, while the other set of samples and sites have curvilinear trends, so a combined line-and-plane analysis was used to determine their characteristic directions. In the upper section of Painted Canyon, samples collected and analyzed thus far yield four well-defined polarity zones in the upper member of the Palm Spring Formation. Interpretation of the polarity zones suggests that the section spans most of the Matuyama chron, including the Jaramillo and the Brunhes-Matuyama boundary. The upper member of the Palm Spring Formation is likely younger than 1.79 Ma (the termination of the Olduvai). Preliminary interpretation of measured anisotropy of magnetic susceptibility (AMS) provides sediment transport/paleocurrent direction from several of the sites, based on the interpretation methods detailed by Tarling and Hrouda (1993) and Tauxe (1998). Plots of minimum, intermediate and maximum susceptibility axes on equal area projections indicate variation of depositional settings through time, represented by the variation in susceptibility axes alignment. Substantial differences are observed between sediment types, with specimens from the two siltiest sites having the most well-defined AMS axis directions. First order analysis of AMS is consistent with a SW paleocurrent direction for the top two sites, a SE or NW paleocurrent direction for mid-section sites and SW or NE paleocurrent direction for lower sites. This interpretation is reasonable considering the provenance and transport direction of the sediments, inferred by McNabb et al. (this meeting). Alternatively, some of the AMS results may be

    Microinclusions in fibrous diamonds carry high density fluids (HDF) with compositions that vary between silicic, carbonatitic and saline end-members. Combining EPMA and FTIR data we can estimate the composition of each end-member. The silicic end-member composition (Udachnaya) comprises ~90 wt% silicates, 4% carbonate, 4% water and minor apatite. The saline end-member (Diavik, Canada) carries 51 wt% alkali halides, 12% carbonates and 37% water. Klein-BenDavid et al. (in review) defined two carbonatitic end-members. The low-Mg one carries ~75 wt% carbonates, 11% silicates, 5% halides, 2% apatite and 7% water; the high-Mg end-member carries similar proportions, except for the higher apatite: 78% carbonates, 9% silicates, 5% apatite, 2% halides and 6% water, but with much higher Mg/(Mg+Fe+Ca) ratio. The volatile-free oxides proportions of the most silicic microinclusions in an Udachnaya diamond are: 69 wt% SiO2; 14% Al2O3; 10% K2O, 2% Na2O, 1% CaO and P2O5 and minor FeO, TiO2, MgO, and Cl. The saline HDF carries 73 wt% KCl, 12% NaCl, 7% CaO, 2.5% MgO, 2.5% BaO, 1.5% FeO and 1.5% SiO2. In the low-Mg carbonatitic HDF calcium exceeds magnesium: ~21 wt% CaO, 18% FeO, 12% MgO, 22% K2O; 10% SiO2, 8% Na2O and minor TiO2, Al2O3, P2O5 and Cl, while in the high-Mg end-member MgO is the main oxide: ~29% MgO, 23% CaO, 7% FeO, 17% K2O, 8% SiO2, 9% Na2O, 2% P2O5 and Cl and minor BaO, TiO2, Cr2O3 and Al2O3 ( all values were calculated on volatile-free basis). Weiss et al., in a companion abstract, suggest that the four end-members form two arrays; one between the saline and the high-Mg carbonatitic compositions and the second between the silicic and the low-Mg carbonatitic ones. They further suggest that the first array represents a process that takes place in a peridotitic environment and the other in an eclogitic one. For example, the arrays may be formed by interaction of hydrous or saline fluids with carbonate-eclogite or with carbonate-peridotite. Safonov et al. (2007

    The Petrified Forest Member of the Triassic Chinle Formation in a Petrified Forest National Park, Arizona may be divided into a lower and upper unit by means of the Sonsela Sandstone Bed. Analysis of fossil vertebrates indicates that the Sonsela Sandstone Bed and upper Petrified Forest Member are characterized by a fauna distinct from that within the lower portion of the Petrified Forest Member. These faunas are believed to be of Norian and Carnian age respectively. Utilizing fossil vertebrates and certain lithostratigraphic units, especially the Sonsela Sandstone Bed and black forest tuff, exposures may be correlated within and between the Rainbow Forest, Blue Mesa, and Painted Desert areas of Petrified Forest National Park.

  7. Conceptual model for transport processes in the Culebra Dolomite Member, Rustler Formation

    1997-08-01

    The Culebra Dolomite Member of the Rustler Formation represents a possible pathway for contaminants from the Waste Isolation Pilot Plant underground repository to the accessible environment. The geologic character of the Culebra is consistent with a double-porosity, multiple-rate model for transport in which the medium is conceptualized as consisting of advective porosity, where solutes are carried by the groundwater flow, and fracture-bounded zones of diffusive porosity, where solutes move through slow advection or diffusion. As the advective travel length or travel time increases, the nature of transport within a double-porosity medium changes. This behavior is important for chemical sorption, because the specific surface area per unit mass of the diffusive porosity is much greater than in the advective porosity. Culebra transport experiments conducted at two different length scales show behavior consistent with a multiple-rate, double-porosity conceptual model for Culebra transport. Tracer tests conducted on intact core samples from the Culebra show no evidence of significant diffusion, suggesting that at the core scale the Culebra can be modeled as a single-porosity medium where only the advective porosity participates in transport. Field tracer tests conducted in the Culebra show strong double-porosity behavior that is best explained using a multiple-rate model.

    1991-03-01

    Recently recovered hominid postcrania from Member 1, Swartkrans Formation include the proximal and distal ends of a right radius attributed to a single individual of Paranthropus robustus. These fossils are essentially similar to Australopithecus afarensis, A. africanus, and P. boisei homologues. The head manifests an ape-like circumferentia articularis, and the distal end has prominent medial, dorsal, and lateral tubercles and a well developed brachioradialis crest, features also commonly exhibited by extant great apes. The volar set of the P. robustus radiocarpal joint, like that of Australopithecus homologues, more closely resembles the neutral condition exhibited by Homo than the greater flexion evinced by living apes. Compared with fossil and recent specimens of Homo, the configuration of the P. robustus radial head suggests enhanced stability against medial displacement during pronation and supination; the strong crest for the attachment of brachioradialis may attest to enhanced forearm flexor capability. In addition, this crest and the prominent dorsal tubercles may indicate enhanced hand extensor and, therefore, hand flexor capabilities. The differences in radial morphology between Paranthropus and Homo may relate to significant behavioral differences between these two synchronic taxa.

    The Painted Rock Sandstone Member of the Miocene Vaqueros Formation in the southeastern Caliente Range, San Luis Obispo County, California, crops out in a narrow band along the anticlinal Caliente Range. The study area is on the eastern flanks of the northwest-trending range. The Painted Rock Sandstone Member is conformably underlain by the Soda Lake Shale Member of the Vaqueros. In the eastern part of the study area, the member is conformably overlain or interfingers with the Oligocene-Miocene Caliente Formation. In the western study area, Painted Rock is conformably overlain by the Miocene Monterey Formation. The Painted Rock Member thickens rapidly to the west with measured thickness ranging from 130 m in the easternmost section to 1800 m in the westernmost and type section. The member generally coarsens upward from interbedded mudstone and fossiliferous, laminated, fine-grained sandstones to cyclical couplets of fossiliferous, medium-grained, cross-bedded sandstones underlying laminated, medium-grained sandstones and local conglomerates. Interspersed within the member is a medium to coarse-grained, structureless sandstone. The Painted Rock generally coarsens to the east, except for almost completely conglomeratic outcrops in a central section. The Painted Rock sequence represents a gradual shoaling from lower-shoreface environments (fine sands and mudstones), to shoreface and foreshore deposits (sandy couplets). The structureless sandstone may fit in this sequence or it may record a subaqueous part of the nearby Caliente delta. The conglomerate section represents a basin-feeding channel. The anomalously thick type section coupled with the conformably overlying deep-marine Monterey Formation records rapid basin subsidence in the western study area.

    Nonmarine deposition accompanying and following a regression of the Cretaceous Interior Seaway during late Turonian time left a sedimentary sequence consisting of fluvial channel sandstones, thin overbank sandstones, and paludal shales containing thin coal beds. This unit is herein designated the Ramah Member of the Crevasse Canyon Formation. The Ramah Member is locally well exposed in the Zuni Basin of west-central New Mexico where it rests on the Gallup Sandstone (marine) and is overlain by the distinctive, feldspathic Torrivio Member of the Crevasse Canyon Formation (formerly of the Gallup Sandstone) Near Ramah, New Mexico the sequence overlies the F member of the Gallup but northward it overlies progressively younger members. These younger members are discrete sand-stone units associated with minor oscillations of relative sea level during a major regional-scale regression. North and east of Puerco Gap, near Gallup. New Mexico, the Ramah Member thins appreciably, and where unmappable it may be included with the Torrivio Member Southward from Gallup in the Zuni Basin. the Ramah locally approaches 150 ft in thickness and contains minable coal beds. The interval was previously referred to as the coal-bearing member of the Gallup (Mapel and Yesberger, 1985) or the Ramah unit (Anderson and Stricker, 1904). In the northern part of the Zuni Basin a problem may exist locally in determinig the top of the Ramah Member. This is due to the presence of fluviel sandstone with coarse-grained facies that looks much the s ame as the Torrivio Member, but underlines it Two criteria may be employed to distiguish the lower sandstone from the Torrivio and properly place it in the strartigraphic succession: (1) the lower sandstone is generally not as feldspathic as the Torrivio nor do the coarse-grained facies contain pebble-size material; and (2) the lower sandstone is not nearly as widespread as the overlying Torrivio. which has a blanket geometry.

    This work examines the major and trace element geochemistry of the pink, laminated Dolomite Member of the Neoprotoerozic Ibex Formation, sampled at high resolution in the Ibex Hills of Death Valley, California. The Dolomite Member of the Ibex Formation directly overlies a basal conglomerate which has lead Corsetti and Kaufman (2005) to speculate that the juxtaposition of these units represents a diamictite - cap carbonate pair. Cap carbonates are inferred to represent deposition under high alkalinity conditions in the shallow ocean at the termination of low latitude glaciation. Increased alkalinity may be driven by the post glacial overturn of anoxic water masses. Here we infer paleoredox conditions during the deposition of the Dolomite Member of the Ibex Formation using trace metal enrichments. The Dolomite Member shows enrichments of Ni, Mo, Fe, Cu, V, Co, and Ba near the base of the unit, and also has a weak overall enrichment in Mn. The enrichment of these metals suggests a period of anoxia during the initial deposition of the Dolomite, and may signal the introduction of basin brines to the shallow ocean during marine transgression. These data are consistent with patterns observed in other cap carbonates worldwide, and support the speculation that the Dolomite Member is a cap carbonate. Alternatively, trace metal enrichments may reflect diagenetic alteration.

    1993-04-01

    Deposition of the Pahrump Group rocks (Crystal Spring-Beck Spring-Kingston Peak Formations) in the Death Valley region of California post-dates 1.7 to 1.4 Ga gneissic basement rocks (Wright et al., 1976) and mostly predates the inferred 0.75 Ga glacial deposits of the Kingston Peak Formation. The 1.08 Ga age of the diabase sills in the middle Crystal Spring Formation provides an additional time constraint. Event though this time span is excessive when compared to better dated Phanerozoic successions, the Pahrump Group, nonetheless, has been assumed to be internally conformable. Results from the authors recent work invalidates that assumption. They have carefully measured 15 sections of upper member Crystal Spring Formation rocks and have mapped in detail the belt of exposures in the Saratoga, Saddle Peak, and Ibex Hills, and northern Kingston Range. Their data indicates that an unconformity of significant but unknown duration occurs within the upper member. Evidence for this unconformity includes: (1) local angular discordance of up to 20[degree]; (2) presence of an erosive-based breccia unit (0.10--30 m thick) that consists mostly of hornfelsic clasts derived from immediately subjacent rocks; and (3) erosional beveling and truncation of underlying rocks. In addition, the upward transition to Beck Spring deposition is marked by a disconformity (sequence boundary) that cuts down across and erosionally truncates strata of the upper member Crystal Spring Formation.

    The middle member of the Bakken Formation is an attractive petroleum exploration target in the deeper part of the Williston Basin because it is favorably positioned with respect to source and seal units. Progressive rates of burial and minor uplift and erosion of this member led to a stable thermal regime and, consequently, minor variations in diagenesis across much of the basin. The simple diagenetic history recorded in sandstones and siltstones in the middle member can, in part, be attributed to the closed, low-permeability nature of the Bakken petroleum system during most of its burial history. Most diagenesis ceased in the middle member when oil entered the sandstones and siltstones in the Late Cretaceous. Most oil in the Bakken Formation resides in open, horizontal fractures in the middle member. Core analysis reveals that sandstones and siltstones associated with thick mature shales typically have a greater density of fractures than sandstones and siltstones associated with thin mature shales. Fractures were caused by superlithostatic pressures that formed in response to increased fluid volumes in the source rocks during hydrocarbon generation

This is the first report of a member of the pteriacean family Pulvinitidae in the Tertiary on either side of the Atlantic, the only other post-Mesozoic records of Pulvinites being in the Paleocene of California and the present-day Pacific off southeast Australia. The stratigraphic setting and co-occurring molluscan assemblage of the new species indicate shallow-shelf, open-marine conditions with near normal salinities. -Authors

  16. Cooperation during cultural group formation promotes trust towards members of out-groups

    People often cooperate with members of their own group, and discriminate against members of other groups. Previous research establishes that cultural groups can form endogenously, and that these groups demonstrate in-group favouritism. Given the presence of cultural groups, the previous literature argues that cultural evolution selects for groups that exhibit parochial altruism. The source of initial variation in these traits, however, remains uninformed. We show here that a group's economic production environment may substantially influence parochial tendencies, with groups formed around more cooperative production (CP) displaying less parochialism than groups formed around more independent production (IP) processes. Participants randomized into CP and IP production tasks formed cultural groups, and subsequently played hidden-action trust games with in-group and out-group trustees. We found CP to be associated with significantly greater sharing and exchanging behaviours than IP. In trust games, significant parochial altruism (in-group favouritism combined with out-group discrimination) was displayed by members of IP groups. By contrast, members of CP groups did not engage in either in-group favouritism or out-group discrimination. Further, we found the absence of out-group discrimination in CP to persist even following ‘betrayal’. Finally, belief data suggest that members of CP are not more intrinsically generous than IP members, but rather more likely to believe that out-group trustees will positively reciprocate. Our results have important implications for anyone interested in building cooperative teams, and shed new light on connections between culture and cooperation. PMID:23658200

    Background Recent revisions to the Sonsela Member of the Chinle Formation in Petrified Forest National Park have presented a three-part lithostratigraphic model based on unconventional correlations of sandstone beds. As a vertebrate faunal transition is recorded within this stratigraphic interval, these correlations, and the purported existence of a depositional hiatus (the Tr-4 unconformity) at about the same level, must be carefully re-examined. Methodology/Principal Findings Our investigations demonstrate the neglected necessity of walking out contacts and mapping when constructing lithostratigraphic models, and providing UTM coordinates and labeled photographs for all measured sections. We correct correlation errors within the Sonsela Member, demonstrate that there are multiple Flattops One sandstones, all of which are higher than the traditional Sonsela sandstone bed, that the Sonsela sandstone bed and Rainbow Forest Bed are equivalent, that the Rainbow Forest Bed is higher than the sandstones at the base of Blue Mesa and Agate Mesa, that strata formerly assigned to the Jim Camp Wash beds occur at two stratigraphic levels, and that there are multiple persistent silcrete horizons within the Sonsela Member. Conclusions/Significance We present a revised five-part model for the Sonsela Member. The units from lowest to highest are: the Camp Butte beds, Lot's Wife beds, Jasper Forest bed (the Sonsela sandstone)/Rainbow Forest Bed, Jim Camp Wash beds, and Martha's Butte beds (including the Flattops One sandstones). Although there are numerous degradational/aggradational cycles within the Chinle Formation, a single unconformable horizon within or at the base of the Sonsela Member that can be traced across the entire western United States (the “Tr-4 unconformity”) probably does not exist. The shift from relatively humid and poorly-drained to arid and well-drained climatic conditions began during deposition of the Sonsela Member (low in the Jim Camp Wash beds), well

    It is common in Neoproterozoic strata worldwide to find 'cap carbonates' overlying inferred glaciogenic diamictites. Despite the fact that many of the contacts are sharp, the relationship between these carbonate units and the underlying diamictites is commonly interpreted to be conformable and to indicate post-glacial transgressive alkalinity events immediately following the aftermath of low-latitude glaciation. If, however, these cap-carbonate units are not conformable with the underlying diamictites, it might imply that they are recording local or global alkalinity events independent of the glacial conditions recorded in the diamictites. The cap carbonate in the Scout Mountain Member of the Pocatello Formation in southeastern Idaho is an excellent site to study the nature of the diamictite to cap-carbonate relationship because the contact is bracketed by two absolute ages: the contact lies ~100 m above a tuff that is 709 Ma and a reworked tuff ~50 m above the contact has been dated at 667 Ma (Fanning and Link, 2004). There is thus ca. 42 million years of time represented in a ~150-m-thick stratigraphic interval implying that there should be at least one unconformity present in this relatively thin stratal package. Most workers have placed a single major sequence boundary/unconformity in this 150-m-thick interval at the top of the cap carbonate, associated with a dolomite-chip breccia unit. Our facies analysis suggests that the most likely place for an unconformity is at the contact between the diamictite and the cap carbonate. The cap carbonate displays a genetic relationship with adjacent and overlying facies, and sits sharply on the diamictite unit (~50 m thick). The cap carbonate comprises pink laminated peloidal dolomicrite (1 m thick) and exhibits rare symmetric and interference ripples, possible hummocky-cross stratification, and negative δ13Ccarb values. Approximately 2 kms along strike, this cap dolomicrite facies is absent and the dolomite-chip breccia

    Measurements have been made on the chemical and physical properties of two oil shales designated as reference oil shales by the Department of Energy. One oil shale is a Green River Formation, Parachute Creek Member, Mahogany Zone Colorado oil shale from the Exxon Colony mine and the other is a Clegg Creek Member, New Albany shale from Kentucky. Material balance Fischer assays, carbon aromaticities, thermal properties, and bulk mineralogic properties have been determined for the oil shales. Kerogen concentrates were prepared from both shales. The measured properties of the reference shales are comparable to results obtained from previous studies on similar shales. The western reference shale has a low carbon aromaticity, high Fischer assay conversion to oil, and a dominant carbonate mineralogy. The eastern reference shale has a high carbon aromaticity, low Fischer assay conversion to oil, and a dominant silicate mineralogy. Chemical and physical properties, including ASTM distillations, have been determined for shale oils produced from the reference shales. The distillation data were used in conjunction with API correlations to calculate a large number of shale oil properties that are required for computer models such as ASPEN. There was poor agreement between measured and calculated molecular weights for the total shale oil produced from each shale. However, measured and calculated molecular weights agreed reasonably well for true boiling point distillate fractions in the temperature range of 204 to 399/sup 0/C (400 to 750/sup 0/F). Similarly, measured and calculated viscosities of the total shale oils were in disagreement, whereas good agreement was obtained on distillate fractions for a boiling range up to 315/sup 0/C (600/sup 0/F). Thermal and dielectric properties were determined for the shales and shale oils. The dielectric properties of the reference shales and shale oils decreased with increasing frequency of the applied frequency. 42 refs., 34 figs., 24

    The Medusae Fossae Formation (MFF) is a geological formation comprising three geological units (members) spread across five principal lobes. It dominates a quarter of the longitudinal extent of the equatorial region of Mars. Positive relief features referred to as ‘sinuous ridges’ (commonly interpreted as inverted paleoflow channel or valley fills) have been observed in the lowest member of the western MFF, but have not been identified within the central and eastern portions of the formation, in the middle and upper members. This paper presents the identification and analysis of a branching, positive relief system which occurs in the central lobe of the MFF in what appears to be an exposure of the middle member. A simple geomorphological map of the system is presented, from which we have adopted the working hypothesis that this is an inverted fill of a branching fluvial channel or valley system. A suite of morphological and topographic evidence supporting this hypothesis is presented, including analysis of the network using a ∼15 m/pixel digital terrain model derived from a Context Imager (CTX) stereo image pair. The evidence supporting this hypothesis includes: (1) the local slope and topography of the upper surface of the network are consistent with a contributory network; (2) the braided, fan-like form at the termination of the branching network is consistent in morphology with it being a depositional fan at the end of a fluvial system; (3) the terminal fan and surrounding deposits show layering and polygonization; and (4) there is strong association between the lower order branches and amphitheater shaped scarps in the depression walls. We evaluate the possible origins of this fluvial system and suggest that seepage sapping is the most probable. Two possible models for the evolution of the network and related features are presented; both require melt of ice within the MFF to form liquid water. We conclude that at least some portions of the Medusae Fossae

    1978-01-01

    The Pen Argyl Member, the upper claystone slate member of the Martinsburg Formation, was studied in three quadrangles in Lehigh and Berks Counties, Pennsylvania. Graptolites collected from the Pen Argyl Member at Lehigh Gap indicate a lower Upper Ordovician (Edenian-Maysvillian) age for the Pen Argyl Member. The Pen Argyl Member in this area is located on the normal limb and in the brow of the large, recumbent Musconetcong nappe. It is a deep water flysch deposit emplaced by turbidity currents from a southeasterly source. Sedimentologic and structural evidence show that the Pen Argyl member overlies the sandy middle Ramseyburg Member, thus supporting the tripartite subdivision of the Martinsburg Formation. Field and thin section study indicates that the penetrative slaty cleavage formed in an indurated rock probably by pressure solution and neocrystallization under lower greenschist facies metamorphism. Strain-slip cleavage formed as a result of a stress couple operating parallel to the slaty cleavage that transposed the slaty cleavage into a more spaced cleavage. Both cleavages are believed to have formed within the same stress continuum and in close succession. Analysis of the folds in the Pen Argyl Member indicate six phases of major and minor folding. The earliest folding, F1, resulted in the development of the recumbent nappe. F2 folds can only be determined statistically; these axes plunge either northeast or southwest Asymmetric folds, F3, and associated F4 crenulations formed within the same stress continuum. F5 folds are large open folds and are exemplified by the Mosservi!le anticline. Kink folds, F6 and associated crenulations are fault related and were the last folds to form. Faults in the Pen Argyl Member range from small displacements along slaty cleavage to large reverse faults. The largest of these, the Eckville fault, is recognized throughout the three quadrangle area. It is a high angle reverse fault that separates the Shochary sequence from the

    The oil source rocks of the Chang 7 member of the Yanchang Formation in the Erdos Basin were deposited during maximum lake extension during the Late Triassic and show a remarkable positive uranium anomaly, with an average uranium content as high as 51.1 μg/g. Uranium is enriched together with organic matter and elements such as Fe, S, Cu, V and Mo in the rocks. The detailed biological markers determined in the Chang 7 member indicate that the lake water column was oxidizing during deposition of the Chang 7 member. However, redox indicators for sediments such as S 2- content, V/Sc and V/(V + Ni) ratios demonstrate that it was a typical anoxic diagenetic setting. The contrasted redox conditions between the water column and the sediment with a very high content of organic matter provided favorable physical and chemical conditions for syngenetic uranium enrichment in the oil source rocks of the Chang 7 member. Possible uranium sources may be the extensive U-rich volcanic ash that resulted from contemporaneous volcanic eruption and uranium material transported by hydrothermal conduits into the basin. The uranium from terrestrial clastics was unlike because uranium concentration was not higher in the margin area of basin where the terrestrial material input was high. As indicated by correlative analysis, the oil source rocks of the Chang 7 member show high gamma-ray values for radioactive well log data that reflect a positive uranium anomaly and are characterized by high resistance, low electric potential and low density. As a result, well log data can be used to identify positive uranium anomalies and spatial distribution of the oil source rocks in the Erdos Basin. The estimation of the total uranium reserves in the Chang 7 member attain 0.8 × 10 8 t.

    A study of the distribution of elements in the Salt Wash member of the Morrison formation of Jurassic age from samples taken in the Jo Dandy area, Montrose County, Colo., was made to determine average chemical composition of mudstone and sandstone and to determine the magnitude of variations in concentrations of elements within similar rock types. Analytical data were obtained by semiquantitative spectrographic and radiometric methods. Results of the study show that variations in concentrations of about 20 elements commonly detected by semiquantititive spectrographic analyses of sedimentary rocks are small for a specific rock type; therefore, considerable confidence may be placed upon the average chemical appears to be no significant relation between chemical composition of mudstone or sandstone and distance from known uranium-vanadium ore or mineralization rock. Mudstone generally contains greater concentrations of the elements studied than sandstone. The chemical composition of red mudstone is similar to the chemical composition of green mudstone except that red mudstone was found to contain almost twice as much calcium as green mudstone in the Jo Dandy area. Samples of the unoxidized sandstone from the Jo Dandy area contain about twice as much calcium, three times as much strontium, but only about one-half as much as zirconium as oxidized sandstone; except for these elements the chemical compositions of both categories of sandstone are similar. Samples of sandstone of the Salt Wash member in the Jo Dandy area contain more potassium, magnesium, vanadium, and nickel than “average sandstone” of the Salt Wash member. The distribution of bismuth in rocks of the Jo Dandy area suggests that bismuth and perhaps part of the potassium and magnesium found in rocks of the Salk Wash member were either derived from solutions which ascended from the underlying salt- and gypsum-bearing Paradox member that was incorporated with rocks of the Salt Wash during sedimentation.

    The Burkholderia cepacia complex (Bcc) consists of 17 closely related species that are problematic opportunistic bacterial pathogens for cystic fibrosis patients and immunocompromised individuals. These bacteria are capable of utilizing two different chemical languages: N-acyl homoserine lactones (AHLs) and cis-2-unsaturated fatty acids. Here we summarize the current knowledge of the underlying molecular architectures of these communication systems, showing how they are interlinked and discussing how they regulate overlapping as well as specific sets of genes. A particular focus is laid on the role of these signaling systems in the formation of biofilms, which are believed to be highly important for chronic infections. We review genes that have been implicated in the sessile lifestyle of this group of bacteria. The new emerging role of the intracellular second messenger cyclic dimeric guanosine monophosphate (c-di-GMP) as a downstream regulator of the fatty acid signaling cascade and as a key factor in biofilm formation is also discussed.

As direct targets of ARF7 and ARF19, Lateral Organ Boundaries Domain 16 (LBD16), LBD29, and LBD18 have a biological function in the formation of lateral roots (LRs). However, the details of the functions of these three LBDs have remained unclear. Each single T-DNA insert mutant has been shown to have slightly fewer LRs than the wild type. We then created a triple mutant, which exhibited a dramatic defect in the LR formation. Our results show that the lbd mutations can lead to impairment in auxin-induced pericycle cell division and in the expression levels of some D-type cyclins (CYCDs). Simultaneously, Plethora (PLT) and PIN-formed (PIN), which have been well documented to promote cell mitotic activity and are required for auxin response effects, were down-regulated by these lbd mutations. Our results so far indicate that CYCDs, PLT, and PINs are the main targets of the LBDs. We believe that these three LBDs are involved in cell cycle progression of the pericycle in response to auxin. Overexpression of any of these three LBD genes in the triple mutant was found incapable of completely replacing the other two LBDs. The phenotypes of lbd29 mutants were not completely consistent with lbd16 or lbd18 mutants. This indicates that LBD29 may play a distinctive role compared with LBD16 or LBD18 and LBDs might play partially independent roles during the formation of LRs.

    Recent studies of the substellar population in the Taurus cloud have revealed a deficit of brown dwarfs compared to the Trapezium cluster population (\\citealt{Briceno-1998,Luhman-2000,Luhman-2003a,Luhman-2004}) However, these works have concentrated on the highest stellar density regions of the Taurus cloud. We have performed a large scale optical survey of this region, covering a total area of ≃ 28 deg2, and encompassing the densest parts of the cloud as well as their surroundings. In this paper, we present optical spectroscopic follow-up observations of 97 photometrically selected potential new low-mass Taurus members. We derive spectral types, visual absorption and luminosity class estimates and discuss our criteria to assess Taurus membership. These observations reveal 5 new very low mass stars (VLMs) and 12 new Brown Dwarfs (BDs) on the Taurus cloud. We derive a new substellar to stellar ratio in Taurus of \\mathcal{R}ss =0.23 ± 0.05. This revisited ratio appears consistent with the value of 0.26 ± 0.04 previously derived in the Trapezium cluster under similar assumptions. We find indications that the relative numbers of BDs with respect to stars is decreased by a factor 2 in the central regions of the aggregates with respect to the more distributed population.

    The development of gametophytes relies on the establishment of a haploid gametophytic generation that initiates with the specification of gametophytic precursors. The majority of flowering plants differentiate a single gametophytic precursor in the ovule: the megaspore mother cell. Here we show that, in addition to argonaute9 (ago9), mutations in other ARGONAUTE (AGO) genes such as ago4, ago6, and ago8, also show abnormal configurations containing supernumerary gametophytic precursors in Arabidopsis thaliana. Double homozygous ago4 ago9 individuals showed a suppressive effect on the frequency of ovules with multiple gametophytic precursors across three consecutive generations, indicating that genetic interactions result in compensatory mechanisms. Whereas overexpression of AGO6 in ago9 and ago4 ago9 confirms strong regulatory interactions among genes involved in RNA-directed DNA methylation, AGO8 is overexpressed in premeiotic ovules of ago4 ago9 individuals, suggesting that the regulation of this previously presumed pseudogene responds to the compensatory mechanism. The frequency of abnormal meiotic configurations found in ago4 ago9 individuals is dependent on their parental genotype, revealing a transgenerational effect. Our results indicate that members of the AGO4 clade cooperatively participate in preventing the abnormal specification of multiple premeiotic gametophytic precursors during early ovule development in A. thaliana.

    It is well established that brief psychoeducational programs for cancer patients will significantly improve mean quality of life. As this kind of adjunctive treatment becomes integrated into general cancer management, it will be necessary to devise cost-effective and efficacious programs that can be offered to relatively large numbers of patients. We have developed a very brief 4-session program that provides this service to 40-80 patients and family members per month (and seems capable of serving much larger numbers, depending on the capacity of the facility in which they assemble). Patients meet in a hospital auditorium for a large group, lecture-style program that offers training in basic coping skills: stress management, relaxation training, thought monitoring and changing, mental imagery and goal setting. Over the first year we have treated 363 patients and 150 family members. Improvements were assessed by changes in the POMS-Short Form, and both patients and family members were found to improve significantly over the course of the program. While this is not a randomized comparison, it suggests that the benefits gained from a large group in a classroom are not substantially less than the improvements that have been documented in the usual small group format, where more interactive discussions are possible.

    The early Paleocene Tullock Member of the Fort Union Formation at its type locality was deposited in a low-gradient riverine system. This interpretation is based on studies of sedimentary structures, geometry, thickness trends, and sand-percent isopach maps. Lithologies consist of interbedded sandstones, siltstones, shales, and thin coal beds. Sandstones 10 m (32.8 ft) thick contain fining-upward, fine-grained, structureless units with erosional bases capped by climbing-ripple lamination. Some sandstones have claystone rip-up clasts at their bases. The sandstones are discrete, highly convex bodies with symmetrical cross sections and flat erosional bases. These sandstone bodies are isolated show no stacking or coalescing, and are concentration in the middle of the Tullock Member. Interbedded calcareous siltstones show ripple cross-laminae and contain elongate calcareous nodules 4 to 16 cm (1.6 to 6.3 in.) long, oriented parallel to the bedding plane. They also contain well-preserved, fragmented leaf impressions. Carbonaceous shale predominates in the upper and lower third of the member. These shales show very thin lamination, contain abundant plant fragments, and have a mottled rooted texture. Thin, discontinuous coal beds are found within the lower third of the Tullock.

    The human mitotic arrest-deficient 2 (Mad2) binding protein p31(comet) participates in the spindle checkpoint and coordinates cell cycle events in mitosis although its function in meiosis remains unknown in all organisms. Here, we reveal P31(comet) as a synaptonemal complex (SC) protein in rice (Oryza sativa L.). In p31(comet), homologous pairing and synapsis are eliminated, leading to the homologous nondisjunction and complete sterility. The failure in loading of histone H2AX phosphorylation (γH2AX) in p31(comet), together with the suppressed chromosome fragmentation in rice completion of meiotic recombination 1 (com1) p31(comet) and radiation sensitive 51c (rad51c) p31(comet) double mutants, indicates that P31(comet) plays an essential role in double-strand break (DSB) formation. Interestingly, the dynamic colocalization pattern between P31(comet) and ZEP1 (a transverse filament protein of SC) by immunostaining, as well as the interaction between P31(comet) and CENTRAL REGION COMPONENT 1 (CRC1) in yeast two-hybrid assays, suggests possible involvement of P31(comet) in SC installation. Together, these data indicate that P31(comet) plays a key role in DSB formation and SC installation, mainly through its cooperation with CRC1.

    The Precambrian carbonate rocks are commonly characteristic of stromatolitic carbonate succession. However, in the western segment of Yanshan area, the third member of the Mesoproterozoic Gaoyuzhuang Formation at the Qiangou section in Yanqing, Beijing, is made up of a set of particular limestone succession with the sparseness of stromatolites. This limestone succession has been defined as the nonstromatolitic carbonate succession, which is a typical example in which three third-order sequences can be discerned according to the cyclicity reflected by successions of sedimentary facies. Within these third-order sequences, there are many subtidal carbonate cycles made up of both the medium- to thin-bedded aphanitic micrites and the thin-bedded marls in the transgressive and the early high-stand system tracts, and many grotesque sedimentary structures are widespread in the bedding planes of aphanitic micrites. These sedimentary structures, including the domal structure, the irregular reticular and chaotic tepee ridges, and the palimpsest ripple, make up an association of the microbial-induced sedimentary structure (MISS). Therefore, both the special MISSs and the particular lithological types make the third member of the Mesoproterozoic Gaoyuzhuang Formation at the Qiangou section to become the representative of the Precambrian nonstromatolitic carbonate succession. More importantly, this succession was formed during the golden age of stromatolite and could provide useful information for the further understanding of the evolving carbonate world of the Precambrian.

    The Vera Member of the Sarmiento Formation at Gran Barranca, Argentina represents one of the few continuous terrestrial records of environmental change across the Eocene-Oligocene Transition (EOT) from the Southern Hemisphere. The Vera Member consists dominantly of sediment in the sand- to silt- size range (median grain size > approximately 10 μm), previously interpreted as pyroclastic deposits interspersed with weakly developed paleosols, deposited within a channel. New grain size data from the Vera Member reveal several intervals of relatively fine-grained sediment (median grain size <10 μm). Magnetic susceptibility varies with a pattern nearly opposite that of median grain size, with the fine-grained intervals characterized by susceptibility slightly above average (> 5 × 10-7 m3/kg), and coarse-grained material characterized by low susceptibilities (< 5 × 10-7 m3/kg). Hysteresis and isothermal remanence acquisition experiments suggest that the susceptibility variations are controlled both by variations in paramagnetic and ferromagnetic mineralogy. More precisely, multi-component coercivity spectra are consistent with at least three remanence carriers: a magnetically hard phase (median Bc ~200 mT) and at least two softer phases (both with median Bc <30 mT). The concentration of these phases varies throughout the section. The high-susceptibility, fine-grained material is consistent with windblown material, possibly volcanic ash. The low-susceptibility, coarser material may indicate leaching during periods between airfall events. There is no evidence of a change in leaching or the deposition of windblown material throughout the Vera Member.

    Human EML4 (EMAP-like protein 4) is a novel microtubule-associated WD-repeat protein of 120 kDa molecular weight, which is classified as belonging to the conserved family of EMAP-like proteins. Cosedimentation assays demonstrated that EML4 associates with in vitro polymerized microtubules. Correspondingly, immunofluorescence stainings and transient expression of EGFP-labeled EML4 revealed a complete colocalization of EML4 with the interphase microtubule array of HeLa cells. We present evidence that the amino-terminal portion of EML4 (amino acids 1-249) is essential for the association with microtubules. Immunoprecipitation experiments revealed that EML4 is hyperphosphorylated on serine/threonine residues during mitosis. In addition, immunofluorescence stainings demonstrated that hyperphosphorylated EML4 is associated with the mitotic spindle, suggesting that the function of EML4 is regulated by phosphorylation. siRNA-mediated knockdown of EML4 in HeLa cells led to a significant decrease in the number of cells. In no case mitotic figures could be observed in EML4 negative HeLa cells. Additionally, we observed a significant reduction of the proliferation rate and the uptake of radioactive [{sup 3}H]-thymidine as a result of EML4 silencing. Most importantly, EML4 negative cells showed a completely modified microtubule network, indicating that EML4 is necessary for correct microtubule formation.

    Structural Health Monitoring (SHM) schemes are useful for proper management of the performance of structures and for preventing their catastrophic failures. Vibration based SHM schemes has gained popularity during the past two decades resulting in significant research. It is hence evitable that future SHM schemes will include robust and automated vibration based damage assessment techniques (VBDAT) to detect, localize and quantify damage. In this context, the Damage Index (DI) method which is classified as non-model or output based VBDAT, has the ability to automate the damage assessment process without using a computer or numerical model along with actual measurements. Although damage assessment using DI methods have been able to achieve reasonable success for structures made of homogeneous materials such as steel, the same success level has not been reported with respect to Reinforced Concrete (RC) structures. The complexity of flexural cracks is claimed to be the main reason to hinder the applicability of existing DI methods in RC structures. Past research also indicates that use of a constant baseline throughout the damage assessment process undermines the potential of the Modal Strain Energy based Damage Index (MSEDI). To address this situation, this paper presents a novel method that has been developed as part of a comprehensive research project carried out at Queensland University of Technology, Brisbane, Australia. This novel process, referred to as the baseline updating method, continuously updates the baseline and systematically tracks both crack formation and propagation with the ability to automate the damage assessment process using output only data. The proposed method is illustrated through examples and the results demonstrate the capability of the method to achieve the desired outcomes.

    The upper member of the 200 m (660 ft) thick Morgan Formation (Middle Pennsylvanian) consists of 5-25 m (16-82 ft) thick, very fine-grained quartz sandstone units that are interbedded repetitively with 0.5-11 m (1.6-36 ft) thick, oolitic, bioclastic, peloidal, and micritic carbonate units. Similar repetitive sequences occur widely in western North America. The quartz sandstone-carbonate cyclothems defined by this study have potential as targets for hydrocarbon exploration. Both eolian dune sandstones and dolomitized shelf carbonate strata are locally important reservoir rocks in the subsurface in parts of the western Overthrust belt in Utah and Wyoming. 84 references, 22 figures, 4 tables.

    Rock magnetic and paleomagnetic data were acquired from the Neoproterozoic Wilburn Rhyolite, the uppermost member of the Mount Rogers Formation, which is thought to have been emplaced during the first phase of break-up of the supercontinent Rodinia along the eastern margin of Laurentia. Several rock magnetic tests show that magnetite is the dominant remanence carrier in these rocks. Response to progressive alternating field and thermal demagnetization by these rocks is excellent and typically yields interpretable results; however, within-sample and between-site dispersion of ChRM is often high. AMS data and remanence data suggest errors in sample orientation in the field. Limited corrections were attempted, resulting a paleomagnetic pole determination of fairly low confidence located at pLat = 64.7N, pLon = 118.8E, a95 = 47.1.

    The sandstones of the Dhosa Sandstone Member of Late Callovian and Early Oxfordian age exposed at Ler have been analyzed for their petrofacies, provenance, tectonic setting and diagenetic history. These sandstones are fine to medium grained and poorly- to well sorted. The constituent mineral grains are subangular to subrounded. These sandstones were derived from a mixed provenance including granites, granite-gneisses, low- and high-grade metamorphic and some basic rocks of the Aravalli Range and Nagarparkar Massif. The petrofacies analysis reveals that these sandstones belong to the continental block-, recycled orogen- and rifted continental margin tectonic regime. The imprints of early and deep burial diagenesis of these sandstones include different stages of compaction, cementation, change in crystal boundaries, cement-cement boundaries, chertification and neomorphism. The sequence of cementation includes precipitation of calcite and its subsequent replacement by Fe calcite and silica cements. The typical intermediate burial (2-3 km depth) diagenetic signatures of these sandstones are reflected in the formation of suture and straight-line boundaries, and triple junctions with straight-line boundaries. The depositional environment, relatively low-energy environment that was below storm wave base but subjected to gentle currents, of the Dhosa Sandstone Member controlled the early diagenesis, which in turn influenced the burial diagenesis of these sandstones.

    Abundant new ichthyosaur material has recently been documented in the Slottsmøya Member of the Agardhfjellet Formation from the Svalbard archipelago of Norway. Here we describe a partial skeleton of a new taxon, Janusaurus lundi, that includes much of the skull and representative portions of the postcranium. The new taxon is diagnosed by a suite of cranial character states including a very gracile stapedial shaft, the presence of a dorsal process on the prearticular and autapomorphic postcranial features such as the presence of an interclavicular trough and a conspicuous anterodorsal process of the ilium. The peculiar morphology of the ilia indicates a previously unrecognized degree of morphological variation in the pelvic girdle of ophthalmosaurids. We also present a large species level phylogenetic analysis of ophthalmosaurids including new and undescribed ichthyosaur material from the Upper Jurassic of Svalbard. Our results recover all Svalbard taxa in a single unresolved polytomy nested within Ophthalmosaurinae, which considerably increases the taxonomic composition of this clade. The paleobiogeographical implications of this result suggest the presence of a single clade of Boreal ophthalmosaurid ichthyosaurs that existed during the latest Jurassic, a pattern also reflected in the high degree of endemicity among some Boreal invertebrates, particularly ammonoids. Recent and ongoing descriptions of marine reptiles from the Slottsmøya Member Lagerstätte provide important new data to test hypotheses of marine amniote faunal turnover at the Jurassic-Cretaceous boundary.

    The taphonomy of Early Permian vertebrates from a sandy facies at the base of the Taquaral Member, Irati Formation, was surveyed in order to acquire data for the interpretation of the sedimentary processes and paleoenvironment of deposition. Six outcrops from the Rio Claro municipality and surrounding areas, from the Brazilian State of São Paulo, were investigated. The vertebrate groups are Chondrichthyes (Xenacanthiformes, Ctenacanthiformes and Petalodontiformes), Osteichthyes (Actinopterygii and Sarcopterygii) and Tetrapodomorpha. They occur as loose teeth, scales, spines and bone remains. The sandy facies is characterized by fining upward deposition. The coarser sandstone immediately above the underlying Tatuí Formation is rich in Chondrichthyes. However, the fine sandstone above, immediately beneath the silty shale facies, is devoid of Chondrichthyes, though Osteichthyes scales, teeth and bones were present. The taphonomy is important for inferring sedimentary processes and then the paleoenvironments. The poor sorting of the sandstone and the presence of fossils that are mostly abraded or worn are indicative of a high energy environment. In contrast, the presence of fossils in a good state of preservation, some without abrasion and breakages are indicative of only limited transport. Differences of fossil spatial density, numbers of specimens and taxa may be explained by the dynamics of deposition, from details of the palaeoenvironment can be obtained.

    The Williamsport Sandstone Member, located at the base of the Wills Creek Formation, contains a complete 5th order sequence, traceable for more than 100 kilometers. This 5th order sequence is initiated with a massive iron-rich sandstone unit. The upper iron-rich sand of the Williamsport Member marks the beginning of the next 5th order sequence. The first 5th order rock cycle, interpreted as the product of the 100 k.y. Milankovitch eccentricity cycle, is divisible into five meter-scale 6th order precessional cycles (PACs). At Cedar Cliff, Maryland, the lithology of each of the five 6th order cycles is distinct. The first cycle (.8m thick) is a massive iron-rich sandstone. The second cycle (.75m thick) is an argillaceous nodular micrite. The third cycle (.75m thick) consists totally of thin-bedded quartz sandstone. The fourth cycle (2m thick) is represented by bedded limestones that thicken upward. The fifth cycle (.6m thick) is very thin-bedded to nodular limestone. This 5th order sequence and most of its internal cyclic elements can be traced over 100 kilometers to Mount Union, Pennsylvania where its facies are largely non-marine. Detailed correlation of these 6th order cycles reveals that the uppermost PAC is missing at Cumberland and Mount Union. At these localities, the prominent iron bed of the next 5th order sequence rests unconformably on the fourth PAC in the sequence. The fifth 6th order cycle was either not deposited or removed by erosion at these proximal localities. The laterally traceable hierarchic cyclic structure in the Williamsport Sandstone is consistent with the Milankovitch forcing model and provides a detailed stratigraphic basis for analysis of lateral patterns of cyclic accumulation in the late Silurian of the central Appalachians.

    The Quail Canyon Sandstone and the Soda Lake Shale Members are the lower members of the Miocene Vaqueros Formation in the southeastern Caliente Range, San Luis Obispo County, California. The Quail Canyon Sandstone Member is conformably underlain by the nonmarine Oligocene Simmler Formation. The Soda Lake Shale Member is conformably overlain by the Painted Rock Sandstone Member of the Vaqueros Formation. The rarely fossiliferous Quail Canyon Sandstone Member is medium to coarse grained and well sorted in its lower half, becoming medium to fine grained upsection. The lower rocks consist of parallel-laminated and large-scale cross-bedded sandstones, representing an upper-shoreface environment. The upper rocks are primarily structureless sandstone and represent a lower-shoreface environment. The entire section ranges in thickness from 50 to 150 m, thinning westward. The Soda Lake Shale Member consists primarily of gray sandy siltstone, brown siltstone, and structureless sandstone. The sandy siltstone and structureless sandstone are interbedded at the bottom of the unit and indicate lower-shoreface to transitional-marine environments. The rocks become progressively finer into the characteristic, usually structureless, brown siltstone of the Soda Lake Shale Member. The brown siltstone represents an offshore environment, perhaps a restricted bay. Farther upsection, the brown siltstone is interbedded with lenticular structureless sandstone, either of which is locally the dominant lithology. Locally interbedded with the upper rocks is organic-rich, clay-rich sandstone. Above the organic sandstone, the other rocks may contain laminations, grading, and channels that are absent to sparse lower in the section. The upper rocks indicate a shallower and more restricted bay alongside a delta. The Soda Lake Shale Member ranges in thickness from 30 m in the east to 350 m in the west.

    The genes encoding the catalytic (pyrB) and regulatory (pyrI) polypeptides of aspartate transcarbamoylase (ATCase, EC 2.1.3.2) from several members of the family Enterobacteriaceae appear to be organized as bicistronic operons. The pyrBI gene regions from several enteric sources were cloned into selected plasmid vectors and expressed in Escherichia coli. Subsequently, the catalytic cistrons were subcloned and expressed independently from the regulatory cistrons from several of these sources. The regulatory cistron of E. coli was cloned separately and expressed from lac promoter-operator vectors. By utilizing plasmids from different incompatibility groups, it was possible to express catalytic and regulatory cistrons from different bacterial sources in the same cell. In all cases examined, the regulatory and catalytic polypeptides spontaneously assembled to form stable functional hybrid holoenzymes. This hybrid enzyme formation indicates that the r:c domains of interaction, as well as the dodecameric architecture, are conserved within the Enterobacteriaceae. The catalytic subunits of the hybrid ATCases originated from native enzymes possessing varied responses to allosteric effectors (CTP inhibition, CTP activation, or very slight responses; and ATP activation or no ATP response). However, each of the hybrid ATCases formed with regulatory subunits from E. coli demonstrated ATP activation and CTP inhibition, which suggests that the allosteric control characteristics are determined by the regulatory subunits.

    The determination of trace element concentrations in oil shale before mining and retorting is required for proper solid-waste management planning. Using routine Fischer assay oil yield data collected during resource characterization as indicators of potential trace element concentrations could lead to a standard method of identifying strata containing high trace element levels. In order to determine a correlation between trace element concentrations and oil yield, shale samples were selected from four statigraphic zones of the Parachute Creek Member of the Green River Formation for analysis. All samples were analyzed for total elemental concentrations, mineralogy, and Fischer assay oil yield. The results of these analyses demonstrated that the Mahogany zone shales contain significantly greater trace element concentrations (antimony, arsenic, cadmium, chromium, copper, lead, lithium, mercury, molybdenum, nickel, selenium, silver, and vanadium) than the other three shale zones. These high trace element concentrations have been identified within well-defined interbedded tuff deposits in the Mahogany zone. In addition, all trace elements evaluated, except boron, show either increasing or decreasing concentrations as oil yield increases within all oil shale zones. With an increased number of analyses of existing oil shale cores, oil yield data will be correlated to specific stratigraphic units containing high trace element concentrations.

    The Qusaiba Member of the Qalibah Formation (Silurian age) is a thick sequence consisting of massive dark gray shales. Only the very basal shales are black and highly organic rich. The basal {open_quote}Hot Shale{close_quote} unit is a prolific source correlated to all the Paleozoic discoveries in Central and Eastern Saudi Arabia. In the Nafud Basin, Northwest Saudi Arabia, this same sequence acts as both source and seal to the underlying Ordovician reservoir, making the understanding of this sequence essential to the current exploration program underway in the region. Acquiring high resolution blostratigraphy and detailed source rock analysis substantially contributed to the better understanding of the regional depositional setting of the seal, source, and the reservoirs in the area. Graptolites and chitinozoans zonation were utilized to fine-tune the chronostratigraphy and to further subdivide this huge basin into more manageable subbasins. Regional chronostratigraphic analysis has indicated that the early Qusaiba transgression took place swiftly and covered all of the Arabian plate during early Rhuddanian time. Only high areas not covered by the Rhuddanian transgression and areas that experienced later uplift and erosion lack the Rhuddanian deposits.

    Techniques of architectural element analysis and lateral profiling have been applied to the fluvial Westwater Canyon Member of the Morrison Formation (Jurassic) in southern San Juan Basin. On a large scale, the sandstone-body architecture consists mainly of a series of tabular sandstone sheets 5-15 m thick and hundreds of meters wide, separated by thin fine-grained units. Internally these sheets contain lateral accretion surfaces and are cut by channels 10-20 m deep and at least 250 m wide. On a more detailed scale, interpretations made from large-scale photomosaics show a complex of architectural elements and bounding surfaces. Typical indicators of moderate- to high-sinuosity channels (lateral accretion deposits) coexist in the same outcrop with downstream-accreted macroform deposits that are typical of sand flats of low-sinuosity, multiple-channel rivers. Broad, deep channels with gently to steeply dipping margins were mapped in several of the outcrops by carefully tracing major bounding surfaces. Locally thick accumulations of plane-laminated and low-angle cross-laminated sandstone lithofacies suggest rapid flow, probably transitional to upper flow regime conditions. Such a depositional style is most typical of ephemeral rivers or those periodically undergoing major seasonal (or more erratic) stage fluctuations, an interpretation consistent with independent mineralogical evidence of aridity. Fining-upward sequences are rare in the project area, contrary to the descriptions of Campbell (1976). The humid alluvial fan model of Galloway (1978) cannot be substantiated and, similarly, the architectural model of Campbell (1976) requires major revision. Comparisons with the depositional architecture of the large Indian rivers, such as the Ganges and Brahmaputra, still seem reasonable, as originally proposed by Campbell (1976), although there is now convincing evidence for aridity and for major stage fluctuations, which differs both from those modern rivers and Campbell

    The White Rim Sandstone Member of the Cutler Formation of Permian age in Canyonlands National Park, Utah, was deposited in coastal eolian and associated interdune environments. This conclusion is based on stratigraphic relationships primary sedimentary structures, and petrologic features. The White Rim consists of two major genetic units. The first represents a coastal dune field and the second represents related interdune ponds. Distinctive sedimentary structures of the coastal dune unit include large- to medium-scale, unidirectional, tabular-planar cross-bedding; high-index ripples oriented parallel to dip direction of the foresets; coarse-grained lag layers; avalanche or slump marks; and raindrop impressions. Cross-bedding measurements suggest the dunes were deposited as transverse ridges by a dominantly northwest to southeast wind. Distinctive sedimentary structures of the interdune pond unit include wavy, horizontally laminated bedding, adhesion ripples, and desiccation polygons. These features may have been produced by alternate wetting and drying of sediment during water-table fluctuations. Evidence of bioturbation is also present in this unit. Petrologic characteristics of the White Rim helped to define the depositional environment as coastal. A crinoid fragment was identified at one location; both units are enriched in heavy minerals, and small amounts of well rounded, reworked glauconite were found in the White Rim throughout the study area. Earlier work indicates that the White Rim sandstone is late Wolfcampian to early Leonardian in age. During this time, the Canyonlands area was located in a depositional area alternately dominated by marine and nonmarine environments. Results of this study suggest the White Rim represents a coastal dune field that was deposited by predominantly on-shore winds during a period of marine transgression.

    Zircons from the Black Forest Bed, Petrified Forest Member, Chinle Formation, in Petrified Forest National Park, yield ages that range from Late Triassic to Late Archean. Grains were analyzed by multigrain TIMS (thermal-ionization mass spectrometry), single-crystal TIMS, and SHRIMP (sensitive, high-resolution ion-microprobe). Multiple-grain analysis yielded a discordia trajectory with a lower intercept of 207 ?? 2 Ma, which because of the nature of multiple-grain sampling of a detrital bed, is not considered conclusive. Analysis of 29 detrital-zircon grains by TIMS yielded U-PB ages of 2706 ?? 6 Ma to 206 ?? 6 Ma. Eleven of these ages lie between 211 and 216 ?? 6.8 Ma. Our statistical analysis of these grains indicates that the mean of the ages, 213 ?? 1.7 Ma, reflects more analytical error than geologic variability in sources of the grains. Grains with ages of ca. 1400 Ma were derived from the widespread plutons of that age exposed throughout the southwestern Cordillera and central United States. Twelve grains analyzed by SHRIMP provide 206Pb*/238U ages from 214 ?? 2 Ma to 200 ?? 4 Ma. We use these data to infer that cores of inherited material were present in many zircons and that single-crystal analysis provides an accurate estimation of the age of the bed. We further propose that, even if some degree of reworking has occurred, the very strong concentration of ages at ca. 213 Ma provides a maximum age for the Black Forest Bed of 213 ?? 1.7 Ma. The actual age of the bed may be closer to 209 Ma. Dating continental successions is very difficult when distinct ash beds are not clearly identified, as is the case in the Chinle Formation. Detrital zircons in the Black Forest Bed, however, are dominated by an acicular morphology with preserved delicate terminations. The shape of these crystals and their inferred environment of deposition in slow-water settings suggest that the crystals were not far removed from their site of deposition in space and likely not far in time

    Pyrope, Mg3Al2Si3O12, due to the abundance of garnet in Earths's upper mantle, has been studied many times. A number of different investigations have measured its physical and thermodynamic properties at high temperature or pressure and, even more recently, under simultaneous high P-T conditions (e.g. Zou et al., 2012). This abstract reports thermal expansion results on pyrope, as part of a much wider project on the determination of the physical properties of garnet, in order to obtain geobarometric information on the formation conditions of its inclusion in diamond. Our experimental approach is based on the elastic method (e.g. Izraeli et al., 1999; Howell et al., 2010; Nestola et al., 2011; Howell et al., 2012), which takes into account the thermoelastic properties of both diamond and any tiny solid phase inclusion within it. The method requires accurate and precise knowledge of thermal expansion and compressibility behavior in order to calculate precisely the pressure and temperature formation conditions of the diamond-inclusion pair. Thus, in order to do this, we measured the thermal expansion of an end-member synthetic single crystal of pyrope up to 1100 K at 52 different temperatures. This was done by measuring the ao unit-cell edge with high precision and accuracy under heating and cooling conditions. This allows excellent experimental reproducibility, which is also checked by monitoring any diffraction peak broadening over the entire range of temperatures. Fitting the temperature-volume data to the thermal expansion equation of Berman (1988), we obtained a room temperature volume-thermal expansion coefficient equal to 2.72(2)×10-5K-1. Using the same pyrope crystal, in situ high-pressure measurements are now in progress in order to determine its isothermal bulk modulus. The use of our results, along with the dK/dT data of Zou et al ( 2012), we plan to calculate the pressure of formation of diamonds containing pyrope-rich garnet inclusions. References Berman

    The organic-rich upper shale member of the upper Devonian–lower Mississippian Bakken Formation (Williston Basin, North Dakota, USA) has undergone significant diagenetic alteration, irrespective of catagenesis related to hydrocarbon generation. Alteration includes precipitation of numerous cements, replacement of both detrital and authigenic minerals, multiple episodes of fracturing, and compaction. Quartz authigenesis occurred throughout much of the member, and is represented by multiple generations of microcrystalline quartz. Chalcedonic quartz fills radiolarian microfossils and is present in the matrix. Sulfide minerals include pyrite and sphalerite. Carbonate diagenesis is volumetrically minor and includes thin dolomite overgrowths and calcite cement. At least two generations of fractures are observed. Based on the authigenic minerals and their relative timing of formation, the evolution of pore waters can be postulated. Dolomite and calcite resulted from early postdepositional aerobic oxidation of some of the abundant organic material in the formation. Following aerobic oxidation, conditions became anoxic and sulfide minerals precipitated. Transformation of the originally opaline tests of radiolaria resulted in precipitation of quartz, and quartz authigenesis is most common in more distal parts of the depositional basin where radiolaria were abundant. Because quartz authigenesis is related to the distribution of radiolaria, there is a link between diagenesis and depositional environment. Furthermore, much of the diagenesis in the upper shale member preceded hydrocarbon generation, so early postdepositional processes were responsible for occlusion of significant original porosity in the member. Thus, diagenetic mineral precipitation was at least partly responsible for the limited ability of these mudstones to provide porosity for storage of hydrocarbons.

    2007-01-01

    Based on petrographic observations of 135 thin sections, rocks in the Meade Peak Phosphatic Shale Member of the Permian Phosphoria Formation in southeastern Idaho can be placed into one of four major lithofacies: organic claystone, muddy siltstone, peloidal phosphorite, and dolomitized calclithite-in order of decreasing abundance. Organic claystones are the most common lithofacies in the Meade Peak. Many of these rocks contain sufficient amounts of silt to make silty, organic claystones a common subtype. Organic claystones commonly contain crystals of muscovite and bioclasts as accessory components, and they are typically parallel laminated. Muddy siltstones are composed primarily of quartz silt, but some feldspar and rare carbonate silt are also present; some rocks are parallel laminated. Phosphate peloids are composed of varying amounts of opaque, complex, and translucent material, and observed internal structures are classified as simple, banded, cored, zoned, oolitic, nucleated, and polynucleated. Opaque, complex, and translucent peloids form the framework grains of three peloidal phosphorite rocks: wackestone phosphorite, packstone phosphorite, and grainstone phosphorite. Wackestone phosphorite is phosphatic-mud supported and contains more than 10 percent peloids; it is the most common type of phosphorite. Packstone phosphorite is peloid supported and contains interstitial phosphatic mud; it is also a common type. Grainstone phosphorite is peloid supported but lacks phosphatic mud; it is the least common type. Dolomitized calclithites contain three types of carbonate grains: macrocrystalline, microcrystalline, and crystalline with a microcrystalline nuclei-in order of decreasing abundance. Based on chemical staining and X-ray diffraction analyses, most of the carbonate is dolomite. Sufficient amounts of quartz silt or muddy material allow some rocks to be called silty dolomitized calclithite or muddy dolomitized calclithite, respectively. Sedimentary

    The evaporites of the Paradox Member of the Hermosa Formation of Pennsylvanian age in southeastern Utah and southwestern Colorado are direct precipitates from marine brines and have been changed only slightly by subsequent events. Geophysical logs of deep wells indicate that the Paradox Member is composed of at least 30 evaporite cycles. Lithologies that make up the cycles, in order of increasing salinity, are organic carbon-rich carbonate shale (black shale), dolomite, anhydrite, and halite (with or without potash). Studies of core from two wells in the central part of the basin show that some of the cycles in the upper part of the Paradox Member are remarkably symmetrical, indicating regular changes in salinity. Detailed petrologic studies have revealed newly recognized lithologic textures and cycle boundaries in 11 evaporite cycles, indicating very regular cyclicity of subaqueous sedimentation in a basin in which salinity was probably controlled by Gondwana glaciation.

    We present results of a spectroscopic survey for new K- and M-type members of Scorpius-Centaurus (Sco-Cen), the nearest OB Association (˜100-200 pc). Using an X-ray, proper motion and colour-magnitude selected sample, we obtained spectra for 361 stars, for which we report spectral classifications and Li and Hα equivalent widths. We identified 156 new members of Sco-Cen, and recovered 51 previously published members. We have combined these with previously known members to form a sample of 493 solar-mass (˜0.7-1.3 M⊙) members of Sco-Cen. We investigated the star formation history of this sample, and re-assessed the ages of the massive main-sequence turn-off and the G-type members in all three subgroups. We performed a census for circumstellar discs in our sample using WISE infrared data and find a protoplanetary disc fraction for K-type stars of 4.4^{+1.6}_{-0.9} per cent for Upper Centaurus-Lupus and Lower Centaurus-Crux at ˜16 Myr and 9.0^{+4.0}_{-2.2} per cent for Upper Scorpius at ˜10 Myr. These data are consistent with a protoplanetary disc e-folding time-scale of ˜4-5 Myr for ˜1 M⊙ stars, twice that previously quoted, but consistent with the Bell et al. revised age scale of young clusters. Finally, we construct an age map of Scorpius-Centaurus which clearly reveals substructure consisting of concentrations of younger and older stars. We find evidence for strong age gradients within all three subgroups. None of the subgroups are consistent with being simple, coeval populations which formed in single bursts, but likely represents a multitude of smaller star formation episodes of hundreds to tens of stars each.

    The Sunnyside Member of the Upper Cretaceous Blackhawk Formation in the Book Cliffs of eastern Utah provides an ideal opportunity to investigate high-resolution sequence-stratigraphic correlation between shallow-marine and terrestrial strata in an area of outstanding outcrop exposure. The thick, laterally extensive coal seam that caps the Sunnyside Member is critical for correlating between its shallow-marine and terrestrial components. Petrographic analysis of 281 samples obtained from 7 vertical sections spanning more than 30 km (18 mi) of depositional dip enabled us to recognize a series of transgressive-regressive coal facies trends in the seam. On this basis, we were able to identify a high-resolution record of accommodation change throughout the deposition of the coal, as well as a series of key sequence-stratigraphic surfaces. The stratigraphic relationships between the coal and the siliciclastic components of the Sunnyside Member enable us to correlate this record with that identified in the time-equivalent shallow-marine strata and to demonstrate that the coal spans the formation of two marine parasequences and two high-frequency, fourth-order sequence boundaries. This study has important implications for improving the understanding of sequence-stratigraphic expression in terrestrial strata and for correlating between marine and terrestrial records of base-level change. It may also have implications for improving the predictability of vertical and lateral variations in coal composition for mining and coalbed methane projects.

    Ab initio QM/MM free-energy simulations were carried out to study the peptide bond formation reaction in the peptidyl transferase center of the ribosome. The QM part of the reaction was treated by density functional theory at the B3LYP/6-31G* level, while the MM part including the solvent and RNA environment was described by molecular force field. The calculated free-energy surfaces for the two popular reaction mechanisms, the six- and eight-membered ring reactions, exhibited large energetic differences which favor the eight-membered reaction mechanism. The simulated quasi-transition state structures clearly indicated a "late" feature consistent with previous theoretical studies. Also the important functional role played by water molecules in the active site of the ribosome and its implication in ribozymic catalysis was discussed in detail.

    A recent U.S. Geological Survey analysis of the Green River Formation of the Piceance Basin in western Colorado shows that about 920 and 352 billion barrels of oil are potentially recoverable from oil shale resources using oil-yield cutoffs of 15 and 25 gallons per ton (GPT), respectively. This represents most of the high-grade oil shale in the United States. Much of this rich oil shale is found in the dolomitic Parachute Creek Member of the Green River Formation and is associated with the saline minerals nahcolite and halite, or in the interval where these minerals have been leached by groundwater. The remaining high-grade resource is located primarily in the underlying illitic Garden Gulch Member of the Green River Formation. Of the 352 billion barrels of potentially recoverable oil resources in high-grade (≥25 GPT) oil shale, the relative proportions present in the illitic interval, non-saline R-2 zone, saline-mineral interval, leached interval (excluding leached Mahogany zone), and Mahogany zone were 3.1, 4.5, 36.6, 23.9, and 29.9 percent of the total, respectively. Only 2 percent of high-grade oil shale is present in marginal areas where saline minerals were never deposited.

    The main turbidite member is the thickest and most extensive of the intervals of prodelta turbidites in the Minturn Formation. Each turbidite interval is part of a coarsening upward sequence interpreted as a prograding fan delta. A typical prograding cycle consists of prodelta marine shale and siltstone, prodelta turbidite sandstones, delta-front sandstone and conglomerate, and deltaic and alluvial-plain sandstone, siltstone, and shale. Fossils of 1and plants (mostly Calamites, including some in growth position) are locally abundant in deltaic and alluvial sediments of the prograding cycles. The turbidites are regarded as having been deposited offshore from alluvial systems.

    Lacustrine strata of the upper part of the Jurassic Wanakah Formation were restricted to the Chama basin of north-central New Mexico by mid-Jurassic tectonic activity in the Brazos and Nacimiento uplifts and along the Gallina-Archuleta anticlinorium. Lateral and vertical facies of the upper Wanakah exposed around the southern margin of the Chama basin indicate that the deeper part of the lake was north of the outcrop belt. The upper 3-5 m of the Wanakah consists of thin-bedded rippled sandstone, interbedded mudstone, and limestone containing trace fossils and freshwater mollusks characteristic of marginal lacustrine facies. Taphonomic studies of mollusks in the Wanakah Formation have been combined with application of ecophenotypic variation documented in extant unionid bivalves to produce paleoenvironmental interpretations of these lacustrine rocks.

  2. Geochemical Analysis of Parasequences within the Productive Middle Member of the Eagle Ford Formation at Lozier Canyon near Del Rio, Texas

    Shane, Timothy E.

    The middle member of the Eagle Ford formation is a heterogeneous, carbonate-shale unit that is a focus of unconventional oil and gas exploration in southern Texas. Exploration results have been mixed because of the apparent heterogeneity of the member. In this study, the extent of heterogeneities in the Eagle Ford on the "bedding-scale" were examined by evaluating changes in organic and inorganic geochemistry. Samples were collected vertically in outcrop covering four non-consecutive parasequences. These samples were analyzed using a Rock Eval 6 Analyzer(TM) to determine source rock generative potential and a Niton(TM) XRF to evaluate inorganic geochemistry to identify changes in paleoredox conditions, paleoproductivity, and clastic influx. From pyrolysis data, it is determined that Parasequence 1 potentially displays an increase in source rock potential, Parasequence 2 potentially displays a constant source rock potential, and Parasequences 3 and 4 potentially display overall decreases in source rock potential during deposition. From the inferred paleoredox conditions, paleoproductivity, and clastic influx, it is determined that Parasequence 1 experienced a potential increase in oxygen abundance, Parasequence 2 experienced a potential decrease in oxygen abundance, and Parasequences 3 and 4 potentially experienced increases in oxygen abundance during deposition. It is concluded that geochemical heterogeneities do exist on a bedding scale within the parasequences of the middle member of the Eagle Ford. Additional comprehensive sampling and analysis is recommended in the future in order to tie these data to subsurface data for economic application.

    2013-12-01

    The upper part of the Jurassic Brushy Basin Member of the Morrison Formation is an iron- and clay-rich volcaniclastic shale deposited in an ephemeral alkaline saline lake system. Sedimentary rocks exposed in Gale Crater consist of similar non-acidic clays, possibly of lacustrine origin. Three primary clastic lithofacies are present in both the Brushy Basin Member and at Gale Crater: silt-/claystone, sandstone, and conglomerate. Both the terrestrial and martian silt-/claystone lithofacies are interpreted as lacustrine depositional environments due to features such as parallel laminated and massive sedimentary structures. Vugs are present in the siltstone/claystone facies on both the Colorado Plateau and at Gale Crater. Fluvial features are also observed in both examples such as cross-bedded sandstones and imbricated conglomerates. Concretions are present in both the Colorado Plateau and Gale Crater units. The vugs in the Brushy Basin Member preserve algal forms with cellular elaboration and are interpreted as charophyte molds. Two distinct suites of elements (1. C, Fe, As, P and, 2. C, S, Se, P) are associated with the microbial fossils and may be potential markers for biosignatures. Vugs at Gale Crater are a potential target to investigate the possibility of preserved microbial (algal) life where early analyses show the presence of the elements capable of supporting life. The Brushy Basin Member is composed predominately of quartz, feldspars, zeolites and altered volcanic ash. The abundant clay minerals in both the terrestrial and martian examples are hypothesized to have formed due to partial alteration of volcanic minerals in alkaline fluid. Similarly, concretions present in the terrestrial unit exhibit a diverse range of mineralogies likely due to alkaline fluid chemistries interacting with reactive volcaniclastic sediments. Terrestrial concretion mineralogy is diverse even within an outcrop or stratigraphic horizon which suggests reactants to precipitate

    The Rio Bonito Member of the San Andres Formation records a transgression of the northwestern shelf during the late Leonardian. Late Leonardian to Guadalupian marine carbonates exposed in the Sacramento Mountains relate a marked change from equatorial tidal flat rocks of the middle Leonardian Yeso Formation. These rocks were deposited during a worldwide sea level lowstand. The Yeso-San Andres contact, previously thought to be a gradational boundary, is here interpreted as a flooding surface resulting from the eustatic sea level rise after the lowstand. Inundation of the northwestern shelf led to deposition of the thick Andres Formation marine limestone sequence within a shallow-lagoon or shelf setting. Depositional environments are predominantly subtidal and intertidal. Microfacies include packstones of comminuted bioclasts of normal saline affinities redistributed by light currents. These shoal upward at times to Dasycladacean algal grainstones interpreted as tidal bars prograding across the lagoon or shelf. More restricted wackestones and laminated mudstones occur at the base of the section and indicate a transition from tidal flat to submerged shelf. Aggradation of sediment into the intertidal zone may have occurred cyclically during San Andres deposition. One such cycle is present over the interval exposed in the Sacramento Mountains. Intertidal rocks resemble tidal flat deposits of dolostone, carbonate mudstones, and a thin tongue of quartzarenite interpeted to be Glorieta Sandstone. These rocks were previously attributed to interginguing of the Yeso with the San Andres.

  5. Spp1, a member of the Set1 Complex, promotes meiotic DSB formation in promoters by tethering histone H3K4 methylation sites to chromosome axes.

    Meiotic chromosomes are organized into arrays of loops that are anchored to the chromosome axis structure. Programmed DNA double-strand breaks (DSBs) that initiate meiotic recombination, catalyzed by Spo11 and accessory DSB proteins, form in loop sequences in promoters, whereas the DSB proteins are located on chromosome axes. Mechanisms bridging these two chromosomal regions for DSB formation have remained elusive. Here we show that Spp1, a conserved member of the histone H3K4 methyltransferase Set1 complex, is required for normal levels of DSB formation and is associated with chromosome axes during meiosis, where it physically interacts with the Mer2 DSB protein. The PHD finger module of Spp1, which reads H3K4 methylation close to promoters, promotes DSB formation by tethering these regions to chromosome axes and activating cleavage by the DSB proteins. This paper provides the molecular mechanism linking DSB sequences to chromosome axes and explains why H3K4 methylation is important for meiotic recombination.

    Functional diversity, defined as the abundance and distribution of traits present in a community, has important implications for the functioning of ecosystems in the wake of events of major disturbance. Here, we examine the functional diversity of a Middle Triassic paleocommunity in the wake of the largest mass extinction in Earth's history, the Permo-Triassic mass extinction (PTME). Field data was collected and analyzed for a highly diverse invertebrate marine fossil assemblage, the Middle Triassic (Anisian) Leidapo Member (Qingyan Formation) of Qingyan, south China. Previously interpreted to represent a fully restructured paleocommunity in the aftermath of the PTME, our results indicate that the fauna of Leidapo Member had high taxonomic diversity and high functional richness, however was functionally uneven. Despite the presence of 24 different functional groups, the paleocommunity was numerically and ecologically dominated by one functional group consisting of mostly attached epifaunal suspension feeding brachiopods. The overwhelming dominance of this Anisian paleocommunity by one functional group implies that either, 1) resource availability in the community was uneven, and/or 2) strong environmental or niche filtering was in effect. As such, while the Anisian Leidapo Member paleocommunity was deposited in a fairly stable shallow water paleoenvironment, this biotic assemblage would have been very vulnerable to biotic and environmental perturbations. While it is uncertain whether or not this pattern is typical of paleocommunities in the aftermath of the PTME, these results imply that some Anisian paleocommunities may not have been as fully restructured as previously thought, and may have been inherently unstable due to the numerous biotic and environmental changes present in the Triassic.

    Benthic macroinvertebrate fossils can be seen towards to the top of the Romualdo Member of the Santana Formation, in the Araripe Basin, Northeast Brazil, and can provide paleoenvironmental and paleobiogeographical information regarding the Cretaceous marine transgression which reached the interior basins in Northeast Brazil. We analyse taphonomic characteristics of macroinvertebrate concentrations of two outcrops (Torrinha and Torre Grande) within the municipality Araripina, Pernambuco, in order to enhance our understanding of the Cretaceous paleoenvironment in the western portion of the Araripe Basin. At the outcrop Torrinha, proximal tempestitic taphofacies were identified. These predominantly consist of ceritid, cassiopid, and later, naticid gastropods as well as undetermined bivalves. Given this lack of variability it can be deduced that there were no significant paleoenvironmental changes during the successive stages tempestitic sedimentation. In the Torre Grande outcrop distal to proximal tempestitic taphofacies were identified from the base to the top respectively pointing to a decrease in paleodepth. Asides from the macroinvertebrates present in Torrinha, there are also echinoids - unequivocal evidence for marine conditions. These occurrences appear to be restricted to Romualdo Member outcrops in the Araripina municipality (the Southeast portion of the Araripe Basin) confirming a previously published hypothesis suggesting that the Cretaceous marine transgression originated from the neighbouring Parnaíba Basin to the west. This study identified marine molluscs of a similar age to those in the Romualdo Member's equivalent rock units in the Parnaíba and Sergipe-Alagoas (SE-AL) basins suggesting a marine connection between these basins and the Araripe Basin during the Early Cretaceous.

    The Shattuck Member is a thick (6-20 m) sandstone that defines the top of the Queen Formation (Permian, Guadalupian) and is a major hydrocarbon reservoir on the Northwestern shelf of the Permian basin. The Shattuck was deposited in desert dune and interdune, dry and wet sand sheet, and sandy sabkha environments during a lowstand of sea level. The desert dune, interdune, and dry sand sheet deposits constitute the producing horizons in the Shattuck, whereas the wet sand sheet and sabkha deposits are generally non-productive. The purposes of this study are to examine the petrographic characteristics of the producing and non-producing horizons with petrographic and scanning electron microscopes, and to determine their provenance and diagenetic history.

    Six facies associations are described for the Puesto Almada Member at the Cerro Bandera locality (Fossati sub-basin). They correspond to lacustrine, palustrine, and pedogenic deposits (limestones); and subordinated alluvial fan, fluvial, aeolian, and pyroclastic deposits. The lacustrine-palustrine depositional setting consisted of carbonate alkaline shallow lakes surrounded by flooded areas in a low-lying topography. The facies associations constitute four shallowing upward successions defined by local exposure surfaces: 1) a Lacustrine-Palustrine-pedogenic facies association with a 'conchostracan'-ostracod association; 2) a Palustrine facies association representing a wetland subenvironment, and yielding 'conchostracans', body remains of insects, fish scales, ichnofossils, and palynomorphs (cheirolepidiacean species and ferns growing around water bodies, and other gymnosperms in more elevated areas); 3) an Alluvial fan facies association indicating the source of sediment supply; and 4) a Lacustrine facies association representing a second wetland episode, and yielding 'conchostracans', insect ichnofossils, and a palynoflora mainly consisting of planktonic green algae associated with hygrophile elements. The invertebrate fossil assemblage found contains the first record of fossil insect bodies (Insecta-Hemiptera and Coleoptera) for the Cañadón Asfalto Formation. The succession reflects a mainly climatic control over sedimentation. The sedimentary features of the Puesto Almada Member are in accordance with an arid climatic scenario across the Upper Jurassic, and they reflect a strong seasonality with periods of higher humidity represented by wetlands and lacustrine sediments.

    The Meade Peak Phosphatic Shale Member of the Phosphoria Formation in the Western Phosphate Field, southeastern Idaho, is composed of carbonaceous mudstone and siltstone with beds of phosphorite and dark bioclastic limestone. An objective of this study has been to understand the timing of diagenetic illite formation in the Meade Peak and whether the Neogene passage of hydrothermal fluids had a significant role in forming diagenetic illite in these shales. Illite-smectite (I-S) is the predominant clay mineral within the shale samples. Smectite, apatite, and kaolinite were also found in some samples. A distinct second generation of diagenetic illite is present as thin, 90% for all samples, and the I-S exhibits a Kalkberg-type stacking order (IISI). The diagenetic conditions inferred from the stacking order and percentage of illite layers in I-S are consistent with published vitrinite reflectance data of the Meade Peak. The K-Ar apparent ages of I-S range from 186 Ma to 292 Ma. A decrease in K-Ar age of I-S with decreasing particle size is observed in clay sub-micron fractions and is consistent with an interpretation that the clay fraction contains a mixture of detrital illite (or I-S) and diagenetic I-S. The measured K-Ar ages of I-S also decrease with increasing stratigraphic distance above the base of the Meade Peak. The K-Ar age of the diagenetic illite rosettes is about 185 Ma. These results indicate that diagenetic illite was formed in the Meade Peak shales during the Jurassic Period, almost certainly in response to progressive burial over a prolonged duration . Additional heating in response to thrust sheet emplacement during the Cretaceous Period may be responsible for the decrease in K-Ar age upward within the member.

  11. A New Centrosaurine Ceratopsid, Machairoceratops cronusi gen et sp. nov., from the Upper Sand Member of the Wahweap Formation (Middle Campanian), Southern Utah

    2016-01-01

    The Upper Cretaceous (middle-late Campanian) Wahweap Formation of southern Utah contains the oldest diagnostic evidence of ceratopsids (to date, all centrosaurines) in North America, with a number of specimens recovered from throughout a unit that spans between 81 and 77 Ma. Only a single specimen has been formally named, Diabloceratops eatoni, from the lower middle member of the formation. Machairoceratops cronusi gen. et sp. nov., a new centrosaurine ceratopsid from the upper member of the Wahweap Formation, is here described based on cranial material representing a single individual recovered from a calcareous mudstone. The specimen consists of two curved and elongate orbital horncores, a left jugal, a nearly complete, slightly deformed braincase, the left squamosal, and a mostly complete parietal ornamented by posteriorly projected, anterodorsally curved, elongate spikes on either side of a midline embayment. The fan-shaped, stepped-squamosal is diagnostic of Centrosaurinae, however, this element differs from the rectangular squamosal in Diabloceratops. Machairoceratops also differs in the possession of two anterodorsally (rather than laterally) curved epiparietal ornamentations on either side of a midline embayment that are distinguished by a posteromedially-oriented sulcus along the entire length of the epiparietal. Additionally, the parietosquamosal frill is lacking any other epiossifications along its periphery. Machairoceratops shares a triangular (rather than round) frill and spike-like epiparietal loci (p1) ornamentation with the stratigraphically lower Diabloceratops. Both parsimony and Bayesian phylogenetic analyses place Machairoceratops as an early-branching centrosaurine. However, the parsimony-based analysis provides little resolution for the position of the new taxon, placing it in an unresolved polytomy with Diabloceratops. The resultant Bayesian topology yielded better resolution, aligning Machairoceratops as the definitive sister taxon to a

    The fossils recovered from the Sterkfontein Formation represent, without doubt, the largest collection of early hominid specimens from a single locality. Among the over 600 entries in the catalogue of fossil hominid specimens recovered since 1966, there are 242 dental remains (isolated teeth, jaws with two or more teeth, isolated teeth in association) for a total number of 495 teeth. The aim of this paper is to provide morphological descriptions of all hominid dental specimens recovered between 1968 and 1996 from areas presently known as Members 4 and 5 of the Sterkfontein site. Together with the descriptions, explanatory catalogue information is provided, along with basic measurements and summary statistics. This paper consists of six sections, with descriptive tables: (1) Catalogue of dental remains, arranged numerically. This includes isolated teeth, specimens with teeth still in position within their jaws, and specimens comprised of isolated teeth in association. (2) List of specimens with more complete dentition and the numbers of available teeth per tooth class. (3) List of specimens subdivided in tooth class, with an indication of their preservation, of the wear, if any, and with measurements (mesiodistal and buccolingual diameters) of the individual teeth. (4) List of associations of isolated teeth as individuals i.e. dental remains that can be associated with one another. Some remarks on the relative abundance of maxillary versus mandibular teeth, and on the numbers of available teeth are presented. (5) Morphological descriptions. (6) Summary statistics for the entire Sterkfontein sample (thus including specimens recovered both before and after 1966) and updated descriptive statistics for South African early hominids (A. africanus, A. robustus, South African early Homo). We have compared the coefficients of variation for the MD and BL diameters of the permanent teeth of the Sterkfontein Member 4 hypodigm of A. africanus with the hypodigms of the early

    The sandstones of the Molina Member of the Wasatch Formation in the Piceance basin of northwestern Colorado contain a suite of fractures that have a conjugate-pair geometry. The fractures are vertical and intersect at an acute angle of between 20 and 40 degrees. Although direct evidence of shear is rare, the fracture surfaces commonly display small steps. The fracture geometries suggest that the maximum compressive stress during fracturing was in the plane of the acute angle of the conjugate fractures: the steps are interpreted as broken-face manifestations of very low angle en echelon fractures, formed within exceptionally narrow zones of incipient shear. In contrast to the highly anisotropic permeability enhancement created by subparallel vertical extension fractures in the underlying Mesaverde Formation, the conjugate pairs in the Molina sandstones should create a well connected and relatively isotropic mesh of fracture conductivity. Increases in stress magnitudes and anisotropy during production drawdown of reservoir pressures should cause shear offsets along the fractures, initially enhancing permeability.

    Previous studies have revealed the presence of pore-scale variability in diffusivity in the Culebra (dolomite) member of the Rustler Formation, NM. In this study, eight laboratory-scale diffusion experiments on five Culebra samples were analyzed using a methodology for modeling solute diffusion through porous media in the presence of multiple matrix diffusivities, Dp. A lognormal distribution of Dp is assumed within each of the lab samples. The estimated standard deviation (sigma d) of ln(Dp) within each sample ranges from 0 to 1, with most values lying between 0.5 and 1. The variability over all samples leads to a combined sigma d in the range of 1.0-1.2, which is consistent with the distribution of independently determined formation factor measurements for similar Culebra samples. A comparison of our estimation results to other rock properties suggests that, at the lab-scale, the geometric mean of Dp increases with bulk porosity and the quantity of macroscopic features such as vugs and fractures. However, sigma d appears to be determined by variability within such macroscopic features and/or by micropore-scale heterogeneity. In addition, comparison of these experiments to those at larger spatial scales suggests that increasing sample volume results in an increase in sigma d.

    The Green River Formation, a large lacustrine deposit located across parts of Utah, Colorado, and Wyoming, was deposited during the Eocene Climatic Optimum (~50 Ma), a period of sustained high temperatures and high atmospheric CO2 levels that may provide a geologic analog for future climate scenarios. Large variations in basin hydrology, water chemistry, and paleotemperatures occurring on time scales of tens of thousands of years or longer have been documented in the sedimentary record. Here, we use stromatolites to investigate much finer-scale resolution of paleoenvironmental changes in the Green River Formation and paleo-Lake Gosiute. We studied the lower LaClede Bed, the base of the Laney Member of the Green River Formation, comprised of cyclic layers of oil shale and carbonate. The lower LaClede Bed represents the filling of the lake following an extended period of closure during deposition of the underlying Wilkins Peak Member. To characterize fluctuations in water chemistry and lake level at greater temporal resolution, we conducted micro-stratigraphic and chemostratigraphic analyses on 24 distinct mm-scale laminae in a single 10 cm carbonate stromatolite bed, including δ13C, δ18O, and trace elemental analyses (Mg, Mn, Fe, Si, K, Na, Al, Sr). Sub-cm-scale correlations between petrographic analyses, elemental composition, and carbonate δ13C and δ18O suggest that this stromatolite records both hydrologically-closed and -open periods in the history of Lake Gosiute. During periods of apparent basin closure, we used two models to investigate lake volume change: 1) a Rayleigh distillation model of water evaporation to estimate lake depth variations and 2) a conservative ion model based on Na incorporation into the stromatolites. In both models, lake depth fluctuated by up to 8 m; this represents up to 40km of shoreline change in Lake Gosiute during the deposition of this stromatolite layer. Interestingly, the modern Great Salt Lake experienced similar

    Oil-yield, lithologic, and mineral distribution data were determined for cores taken from a 497.7-foot drill hole in the upper part of the Parachute Creek Member of the Eocene Green River Formation. The drill hole, 1050 feet FEL, 700 feet FNL, sec. 3, T. 12 S., R. 24 E., Uintah County, Utah, started slightly below the contact between the Uinta Formation, also of Eocene age, and the underlying Green River Formation. It ended 32 feet below the base of the Mahogany bed (the richest oil-shale bed between A groove and B groove--which define the upper and lower boundaries, respectively, of the Mahogany zone). Most of the interval studied is kerogen- or carbonate-rich, commonly tuffaceous, and is very fine grained. Several thin (<3 feet) oil-shale beds which yield as much as 25 gallons of oil per ton occur above the Mahogany zone, but are probably not of economic interest. The cored sequence contains several tuff beds. The thickest of these beds is approximately 2 feet thick; the average thickness is rarely greater than 0.5 feet. Two oil-saturated tuff beds occur approximately 65 feet above the Mahogany oil-shale bed. Although these two tuffs are exposed on nearby surface outcrops, no evidence of oil is seen on outcrop. The Mahogany zone is approximately 69 feet thick at the drill site; the lowermost few feet were not penetrated. At the site cored, the Mahogany zone is overlain by 435 feet of overburden. Fischer assays indicate that 42.3 feet of oil shale within the Mahogany zone could yield at least 25 gallons of oil per ton from beds at least 10 feet thick.

    The Permian Caldeirão Member (Santa Brígida Formation), located in the Tucano Central Basin, northeast region of Brazil, is characterized by a sandstone succession of aeolian origin that comprises the preserved deposits of dunes and interdunes. Grainflow and translatent wind-ripple strata, and frequent presence of reactivation surface, compose the cross-bedding of crescent aeolian dune deposits. The aeolian cross-strata show a mean dip toward the ENE. In places, interlayered with dune cross-beds, occur interdune units composed of facies indicative of dry, damp and wet condition of the substrate, suggesting spatial and/or temporal variations in the moisture content of the interdune accumulation surface. The presence of NNW current ripple cross-lamination in wet interdune areas indicates streamflows confined to interdune corridors and oriented perpendicular to aeolian transport direction. Lenses of damp and wet interdune strata exhibit mainly interdigitated and transitional relationships with the toe-sets of overlying aeolian dune units in sections parallel to aeolian transport, indicating that dune migration was contemporaneous with accumulation in adjacent interdunes. Lateral variations in the preserved thickness of the interdune units and the associated rare occurrence of abrupt and erosive contacts between interdune and overlying dune sets, suggest temporal variations in the angle of dune and interdune climb that may be related to high-frequency changes in water table position. Four stratigraphic intervals in the Caldeirão Member can be identified, two intervals showing cross-bedding of aeolian dunes without wet interdune areas and two intervals exhibiting aeolian dunes separated by wet interdune areas, marking the transition between dry aeolian systems (Intervals I and III) and wet aeolian systems (Intervals II and IV). The temporal alternations between dry and wet aeolian systems reflect changes in the availability of dry sand and/or the rate in the water

    The upper part of the Brushy Basin Member in the Four Corners region of the U.S. was deposited in an ephemeral alkaline saline lake system with copious input of volcanic ash. The variegated shale formation provides a setting for the study of early diagenetic iron cycling that records the action of alkaline saline fluid chemistries reacting with volcaniclastic sediments in the presence of microbes. A bull's-eye pattern of authigenic minerals with increasing alteration towards the basinal center similar to modern alkaline saline lakes provides evidence for an extreme paleoenvironmental interpretation. The purpose of this research is to document specific factors, such as reactive sediments, microbial influences, and grain size that affect concretion formation and iron cycling in an ancient extreme environment. Three broad diagenetic facies are interpreted by color and associated bioturbation features: red, green and intermediate. Diagenetic facies reflect meter-scale paleotopography: red facies represent shallow water to subaerial, oxidizing conditions; green facies reflect saturated conditions and reducing pore water chemistry shortly after deposition, and intermediate facies represent a combination of the previous two conditions. Evidence of biotic influence is abundant and trace fossils exhibit patterns associated with the diagenetic facies. Red diagenetic facies typically contain burrows and root traces and green diagenetic facies exhibit restricted biotic diversity typically limited to algal molds (vugs). Microbial fossils are well-preserved and are in close proximity to specific iron mineral textures suggesting biotic influence on the crystal morphology. Three categories of concretions are characterized based on mineralogy: carbonate, iron (oxyhydr)oxide and phosphate concretions. Concretion mineralogy and size vary within an outcrop and even within a stratigraphic horizon such that more than one main category is typically present in an outcrop. Variation in

    A continuous succession of Cretaceous through lowermost Eocene terrestrial sediments contains a nearly complete Paleocene record, in the Little Missouri River Valley of North Dakota, USA. We aim to calibrate the rates of post-Cretaceous ecological recovery from mass extinction, by determining a detailed chronostratigraphy of plant and mammal fossils in the basin. Using the Cretaceous-Paleogene (K-T) boundary as the basal datum, we have constructed a ca.300 meter composite section of the Upper Cretaceous Hell Creek Formation and the Lower Paleocene Ludlow Member of the Fort Union Formation. We analyzed paleomagnetic samples from 12 stratigraphic sections using a combined low-AF and thermal demagnetization strategy. Instability of magnetization above 200 °C has been reported in previous studies, which we reproduced when heating in air; however, when the samples were heated in nitrogen the stability field extended to well above 300 °C. The analyzed samples demonstrate a series of geomagnetic reversals that can be correlated from C29n through C27r of the Geomagnetic Polarity Time Scale (GPTS). Bulk susceptibility vs. temperature studies on sandstone, siltstone, and carbonaceous shale indicate predominately irreversible curves suggesting titanomaghemite as the magnetic carrier in the Ludlow Member sediments. IRM acquisition in our samples consistently shows non-saturation above 100 mT indicating an additional anti-ferromagnetic component, most likely goethite. The dominant iron oxide in these samples, titanomaghemite, was generated either during weathering of the source terrain during Laramide uplift, or weathered in-situ prior to diagenesis, or during alteration after burial. We infer that the magnetization of the samples is primary because the polarity direction is consistent with that of the Paleocene of North America and the reversal stratigraphy from this section corresponds to the GPTS with reasonable sedimentation rates. Our results imply a temporal restriction

    The Ordovician Suri Formation is part of the infill of the Famatina Basin of northwest Argentina, which formed in an active setting along the western margin of early Paleozoic Gondwana. The lower part of this formation, the Vuelta de Las Tolas Member, records sedimentation on a slope apron formed in an intra-arc basin situated on a flooded continental arc platform. The coincidence of a thick Arenig-Llanvirn sedimentary succession and volcanic-plutonic arc rocks suggests an extensional or transtensional arc setting, and is consistent with evidence of an extensional regime within the volcanic arc in the northern Puna region. The studied stratigraphic sections consist of volcanic rocks and six sedimentary facies. The facies can be clustered into four facies associations. Association 1, composed of facies A (laminated siltstones and mudstones) and B (massive mudstones and siltstones), is interpreted to have accumulated from silty-muddy high-and low-density turbidity currents and highly fluid, silty debris flows, with subsequent reworking by bottom currents, and to a lesser extent, hemipelagic suspension in an open-slope setting. Facies association 2 is dominated by facies C (current-rippled siltstones) strata. These deposits are interpreted to record overbank sedimentation from fine-grained turbidity currents. Facies E (matrix-supported volcanic breccias) interbedded with andesitic lava units comprises facies association 3. Deposition was contemporaneous with subaqueous volcanic activity, and accumulated from cohesive debris flows in a coarse-grained wedge at the base of slope. Facies association 4 is typified by facies D (vitric fine-grained sandstones and siltstones) and F (channelized and graded volcanic conglomerates and breccias) deposits. These strata commonly display thinning-and fining-upward trends, indicating sedimentation from highly-concentrated volcaniclastic turbidity currents in a channelized system. The general characteristics of these deposits of fresh

Our parent sample is the kinematically selected Hipparcos sample of de Zeeuw et al., restricted to the 138 F-type members. We have obtained classification-resolution optical spectra and have also determined the spectroscopic accretion disk fraction. With Hipparcos and 2MASS photometry, we estimate the reddening and extinction for each star and place the candidate members on a theoretical H-R diagram. For each subgroup we construct empirical isochrones and compare to published evolutionary tracks. We find that (1) our empirical isochrones are consistent with the previously published age-rank of the Sco-Cen subgroups; (2) subgroups LCC and UCL appear to reach the main-sequence turn-on at spectral types {approx}F4 and {approx}F2, respectively. An analysis of the A-type stars shows US reaching the main sequence at about spectral type {approx}A3. (3) The median ages for the pre-main-sequence members of UCL and LCC are 16 Myr and 17 Myr, respectively, in agreement with previous studies, however we find that (4) Upper Sco is much older than previously thought. The luminosities of the F-type stars in US are typically a factor of {approx}2.5 less luminous than predicted for a 5 Myr old population for four sets of evolutionary tracks. We re-examine the evolutionary state and isochronal ages for the B-, A-, and G-type Upper Sco members, as well as the evolved M supergiant Antares, and estimate a revised mean age for Upper Sco of 11 {+-} 1 {+-} 2 Myr (statistical, systematic). Using radial velocities and Hipparcos parallaxes we calculate a lower limit on the kinematic expansion age for Upper Sco of >10.5 Myr (99% confidence).

    A newly discovered vertebrate assemblage is reported from the Upper Pennsylvanian (mid-to upper Kasimovian) Cohn Coal Member of the Mattoon Formation of southeast Illinois, United States. Teeth, scales, and spines of xenacanth (Dicentrodus, Orthacanthus, Triodus, Xenacanthus) and euselachian (Sphenacanthus) sharks dominate the assemblage. Less common are the teeth, scales, and centra of holocephalan (Helodus) and actinopterygian fishes, together with rare tetrapod (mainly pelycosaur) phalanges and centra. The assemblage occurs within a broad, shallow channel incised into a prominent Vertisol. The channel is interpreted as having been cut during a seasonally dry glacial phase when sea level was low, but filled during a subsequent transgression triggered by deglaciation. We interpret this as a brackish water (estuarine) assemblage, based on the co-occurrence of the vertebrate material with spirorbids (putative microconchids) and paleoecological inferences gleaned from a critical analysis of the literature dealing with Pennsylvanian fish ecology. This interpretation is broadly consistent with taphonomic data and the results of 87Sr/86Sr isotope analysis of shark material. The pelycosaur material may have been reworked from the lowstand Vertisol, however, and these animals occupied dryland niches that developed during glacial phases. ?? 2011 SEPM (Society for Sedimentary Geology).

    The environmental conditions under which rocks in the Paleocene Tongue River Member of the Fort Union Formation were deposited in the Powder River area, Wyoming and Montana, can be determined using geophysical logs with some limitations. It is widely recognized that gamma ray and density logs are useful in identifying thickness and stratigraphic position of coal beds. In addition, gamma ray and electrical resistivity logs can be used to infer conditions of transportation and deposition of sandstones, siltstones, and other rock types. In particular, intensity responses of the gamma ray and resistance logs provide a clue to variations of grain size such as fining-upward and coarsening-upward characteristics of fluvial channel and crevasse splay deposits, respectively. These signatures in the geophysical logs are readily observed for some beds; for other beds however, the depositional conditions are difficult to determine because the beds do not produce clear-cut log-response patterns. Thus,. analysis of the environments of deposition of detrital rocks in drill holes can be made more accurate by a study of stratigraphically equivalent intervals in outcrops near drill-hole sites.

    While the oxygen isotopic composition of pedogenic carbonate has successfully been used to address the effects of global climate change on the hydrologic cycle, detailed regional paleohydrologic studies are lacking. Since the hydrologic cycle can vary extensively on local or regional scales due to events such as such as mountain building, and since pedogenic carbonates (calcite) form in a narrow moisture regime, other proxies, such as vertebrate remains, must be used to decipher local versus regional variations in paleohydrology. In this study, the oxygen isotopic composition (?? 18O p) of phosphatic remains from a diverse set of vertebrate fossils (fish, turtles, crocodiles, dinosaurs, and micro-mammals) from the Mussentuchit Member (MM) of the Cedar Mountain Formation, Utah, USA (Aptian to Cenomanian) are analyzed in order to determine differences among the available water reservoirs and water utilization of each taxon. Calculated changes in water reservoir ?? 18O w over time are then used to determine the effects of the incursion of the Western Interior Seaway (WIS) and the Sevier Mountains on paleohydrology during the MM time. Calculation of ?? 18O w from the results of isotopic analysis of phosphate oxygen suggests that turtles and crocodiles serve as another proxy for meteoric water ?? 18O that can be used as a measure of average local precipitation ?? 18O w similar to pedogenic calcite. Pedogenic calcites can be slightly biased toward higher values, however, due to their formation during evaporative conditions. Turtles and crocodiles can be used in place of pedogenic calcite in environments that are not conducive to pedogenic carbonate formation. Remains of fish with rounded tooth morphology have ?? 18O p values that predict temperatures consistent with other estimates of mean annual temperature for this latitude and time. The ?? 18O p of ganoid scales and teeth with pointed morphology, however, indicates that these skeletal materials were precipitated from

    The second and third member of the Qingshankou Formation recovered by CCSD-SK-Is borehole (China Cretaceous Continental Scientific Drilling-SongkeI-the south borehole) is 415.61 m long and 100% of cores recovery. The age of the member corresponds approximately to the Coniacian. The sequence and process of lithology-lithofacies and cyclic stratigraphy were revealed by a detailed core description. 12 rock types and 2 kinds of sedimentary subfacies including semi-deep lake and shallow lake were recognized from the drilling core of the second and third member of the Qingshankou Formation. 10 sedimentary microfacies are present, including dolomite, marl, limestone, oil shale, semi-deep lake turbidite, volcanic ash, seismite, semi-deep lake mudstone, shallow lake mudstone, and shallow lake turbidite microfacies. The second and third member of the Qingshankou Formation represents 422 meter-scale cycles (sixth-order cycle), 130 fifth-order cycles, 21 fourth-order cycles, and one third-order cycles. The special lithologies, such as mudstone, seismite, dolomite, volcanic ash, and so on are important to researches on source rocks and lacustrine event sediments.

  12. Imaging the Ferron Member of the Mancos Shale formation using reprocessed high-resolution 2-D seismic reflection data: Emery County, Utah

    2003-01-01

    Late in 1982 and early in 1983, Arco Exploration contracted with Rocky Mountain Geophysical to acquired four high-resolution 2-D multichannel seismic reflection lines in Emery County, Utah. The primary goal in acquiring this data was an attempt to image the Ferron Member of the Upper Cretaceous Mancos Shale. Design of the high-resolution 2-D seismic reflection data acquisition used both a short geophone group interval and a short sample interval. An explosive energy source was used which provided an input pulse with broad frequency content and higher frequencies than typical non-explosive Vibroseis?? sources. Reflections produced by using this high-frequency energy source when sampled at a short interval are usually able to resolve shallow horizons that are relatively thin compared to those that can be resolved using more typical oil and gas exploration seismic reflection methods.The U.S. Geological Survey-Energy Resources Program, Geophysical Processing Group used the processing sequence originally applied by Arco in 1984 as a guide and experimented with processing steps applied in a different order using slightly different parameters in an effort to improve imaging the Ferron Member horizon. As with the Arco processed data there are sections along all four seismic lines where the data quality cannot be improved upon, and in fact the data quality is so poor that the Ferron horizon cannot be imaged at all.Interpretation of the seismic and core hole data indicates that the Ferron Member in the study area represent a deltaic sequence including delta front, lower delta plain, and upper delta plain environments. Correlating the depositional environments for the Ferron Member as indicated in the core holes with the thickness of Ferron Member suggests the presence of a delta lobe running from the northwest to the southeast through the study area. The presence of a deltaic channel system within the delta lobe complex might prove to be an interesting conventional

    The Miocene-Pliocene Manzanilla Formation of northern Trinidad marks the arrival of the east-west flowing Orinoco River. Foraminifera were examined quantitatively in samples obtained at ˜5 m intervals from the lowest member of the formation, the San José Calcareous Silt Member, where exposed at eastern Manzanilla Bay and Point Noir. Recovery of Globorotalia merotumida indicates an age within the Globorotalia acostaensis Zone through Globorotalia margaritae evoluta Subzone, (N16-N19). Values of the information function (H) and the percentage of the total assemblage as planktonic foraminifera (%P), both traditionally used as palaeodepth indicators, were uncorrelated. The low values of H are indicative of freshwater influence. Cluster analysis revealed two major biofacies dominated by Pseudononion atlanticum and Hanzawaia carstensi respectively, for which similar values of mean H and mean %P suggest similar, inner to middle neritic palaeodepths, the P. atlanticum Biofacies indicating times of hypoxia. Entrained within these were rarer samples from a biofacies indicative of shallowing and increased freshwater input (Ammonia parkinsonia gr. Biofacies). An Amphistegina gibbosa Biofacies marked an interval in which water because sufficiently clear to support foraminifera symbiotic with algae, while a sample containing only Haplophragmoides wilberti was indicative of intertidal conditions. Some samples containing reddened foraminifera showed that deposition occasionally became very slow, but these were not limited to any one biofacies. The range of palaeodepths in which the San José Calcareous Silt Member was deposited is far less than in the underlying Brasso Formation, indicating that tectonic induction of transgressive-regressive cycles was slighter during San José times.

    Synthesis of the lactone core 17 of 8-epi-griseoviridin is reported. Thioethynyl derivative 11 was easily prepared via an anionic coupling reaction between acetylenic compound 9 and sulfone 10. After desilylation of 11, saponification of the resulting hydroxy ester 12 followed by a Mitsunobu macrolactonization furnished the unusual triple-bond-containing nine-membered lactone 13 in 50% yield for the last two steps (39% after recrystallization). Stannylation under Magriotis conditions led to the pure regio- and stereocontrolled vinyltin 14 (80% yield). After a Sn/I exchange, palladium-catalyzed carbonylation delivered either the ester lactone 16 in 67% yield or the propargyl amide 17 in 65% yield. Synthesis of propargyl amide 17 of the lactone core of 8-epi-griseoviridin was achieved in 11.9% overall yield from commercial L-cystin dimethyl ester (nine steps).

    The ribosome is the macromolecular machine that catalyzes protein synthesis. The kinetic isotope effect analysis reported by Strobel group supports the two-step mechanism. However, the destination of the proton originating from the nucleophilic amine is uncertain. A computational simulation of different mechanisms including water molecules is carried out using the same reaction model and theoretical level. Formation the tetrahedral intermediate with proton transfer from nucleophilic nitrogen, is the rate-limiting step when two water molecules participate in peptide bond formation. The first water molecule forming hydrogen bonds with O9‧ and H15‧ in the A site can decrease the reaction barriers. Combined with results of the solvent isotope effects analysis, we conclude that the three-proton transfer mechanism in which water molecule mediate the proton shuttle between amino and carbon oxygen in rate-limiting step is the favorable mechanism. Our results will shield light on a better understand the reaction mechanism of ribosome.

    Although the multilayered structure of the plant cuticle was discovered many years ago, the molecular basis of its formation and the functional relevance of the layers are not understood. Here, we present the permeable cuticle1 (pec1) mutant of Arabidopsis thaliana, which displays features associated with a highly permeable cuticle in several organs. In pec1 flowers, typical cutin monomers, such as ω-hydroxylated fatty acids and 10,16-dihydroxypalmitate, are reduced to 40% of wild-type levels and are accompanied by the appearance of lipidic inclusions within the epidermal cell. The cuticular layer of the cell wall, rather than the cuticle proper, is structurally altered in pec1 petals. Therefore, a significant role for the formation of the diffusion barrier in petals can be attributed to this layer. Thus, pec1 defines a new class of mutants. The phenotypes of the pec1 mutant are caused by the knockout of ATP BINDING CASSETTEG32 (ABCG32), an ABC transporter from the PLEIOTROPIC DRUG RESISTANCE family that is localized at the plasma membrane of epidermal cells in a polar manner toward the surface of the organs. Our results suggest that ABCG32 is involved in the formation of the cuticular layer of the cell wall, most likely by exporting particular cutin precursors from the epidermal cell.

    This paper presents a new method for recovering paleoporosity of sandstone reservoirs and quantitatively defines the evolution process of porosity. This method is based on the principle that the present is the key to the past. We take the middle Es3 member in Niuzhuang Sag, Dongying Depression, and Bohai Bay Basin as an example. The method used in this study considers the present porosity as a constraint condition, and the influences of both constructive diagenesis and destructive diagenesis to divide the porosity evolution process into two independent processes, namely porosity increase and porosity decrease. An evolution model of sandstone porosity can be established by combining both the pore increase and pore decrease effects. Our study reveals that the porosity decrease model is a continuous function of burial depth and burial time, whereas the porosity increase model mainly occurs in an acidified window for paleotemperature of 70°C to 90°C. The porosity evolution process can be divided into the following phases: normal compaction, acidification and pore increase, and post-acidification compaction. Thus, the porosity evolution model becomes a piecewise function of three subsections. Examples show that the method can be applied effectively in recovering the paleoporosity of sandstone reservoirs and simulating the porosity evolution process.

    The O-methylation of various secondary metabolites is mainly catalyzed by S-adenosyl-l-methionine (SAM)-dependent O-methyltransferase (OMT) proteins that are encoded by the O-methyltransferase gene family. Citrus fruits are a rich source of O-methylated flavonoids that have a broad spectrum of biological activities, including anti-inflammatory, anticarcinogenic, and antiatherogenic properties. However, little is known about this gene family and its members that are involved in the O-methylation of flavonoids and their regulation in Citrus. In this study, 58 OMT genes were identified from the entire Citrus sinensis genome and compared with those from 3 other representative dicot plants. A comprehensive analysis was performed, including functional/substrate predictions, identification of chromosomal locations, phylogenetic relationships, gene structures, and conserved motifs. Distribution mapping revealed that the 58 OMT genes were unevenly distributed on the 9 citrus chromosomes. Phylogenetic analysis of 164 OMT proteins from C.sinensis, Arabidopsis thaliana, Populus trichocarpa, and Vitis vinifera showed that these proteins were categorized into group I (COMT subfamily) and group II (CCoAOMT subfamily), which were further divided into 10 and 2 subgroups, respectively. Finally, digital gene expression and quantitative real-time polymerase chain reaction analyses revealed that citrus OMT genes had distinct temporal and spatial expression patterns in different tissues and developmental stages. Interestingly, 18 and 11 of the 27 genes predicted to be involved in O-methylation of flavonoids had higher expression in the peel and pulp during fruit development, respectively. The citrus OMT gene family identified in this study might help in the selection of appropriate candidate genes and facilitate functional studies in Citrus.

    2015-08-01

    The Puesto Díaz Quarry (Lohan Cura Formation, Lower Cretaceous of Neuquén Basin, Argentina) consists of a monospecific dinosaur bone assemblage that includes 126 specimens from, at least, three individuals of the rebbachisaurid sauropod Comahuesaurus windhauseni. The bonebed was originated as a debris flow of an ephemeral-river bed, in distal areas of low relief. Bones are disarticulated, three-dimensionally distributed through the host facies, showing a normal grading arrangement, which can be correlated with the size, shape and hydraulic behavior inferred for each specimen. Taphonomic evidence suggests that the bones did not experience a prolonged transport, and that these were quickly buried by the debris flow event. The fact that there are more than one individual of the same species suggests a mass mortality by a catastrophic event. Scattered skeletal elements would indicate that the corpses must have been subaerially exposed, long enough to allow disarticulation by scavenging, decay, and defleshing.

    Statistical treatment of analytical data from the Mariano Lake and Ruby uranium deposits in the Smith Lake district, New Mexico, indicates that organic carbon, arsenic, barium, calcium, cobalt, copper, gallium, iron, lead, manganese, molybdenum, nickel, selenium, strontium, sulfur, vanadium, yttrium, and zirconium are concentrated along with uranium in primary ore. Comparison of the Smith Lake data with information from other primary deposits in the Grants uranium region and elsewhere in the Morrison Formation of the Colorado Plateau suggests that these elements, with the possible exceptions of zirconium and gallium and with the probable addition of aluminum and magnesium, are typically associated with primary, tabular uranium deposits. Chemical differences between the Ruby and Mariano Lake deposits are consistent with the interpretation that the Ruby deposit has been more affected by post-mineralization oxidizing solutions than has the Mariano Lake deposit.

    The U.S. Geological Survey (USGS) has studied the Permian Phosphoria Formation in southeastern Idaho and the entire Western U.S. Phosphate Field throughout much of the twentieth century. In response to a request by the U.S. Bureau of Land Management, a new series of resource, geological, and geoenvironmental studies was undertaken by the USGS in 1998. To accomplish these studies, the USGS has formed cooperative research relationships with two Federal agencies, the Bureau of Land Management and the U.S. Forest Service, tasked with land management and resource conservation on public lands; and with five private companies currently leasing or developing phosphate resources in southeastern Idaho. The companies are Agrium U.S. Inc. (Rasmussen Ridge mine) , Astaris LLC (Dry Valley mine), Rhodia Inc. (Wooley Valley mine, inactive), J.R. Simplot Company (Smoky Canyon mine), and Monsanto Co. (Enoch Valley mine). Some of the mineralogical research associated with this project is supported through a cooperative agreement with the Department of Geology and Geological Enginee ring, University of Idaho. Present studies consist of integrated, multidisciplinary research directed toward (1) resource and reserve estimations of phosphate in selected 7.5-minute quadrangles; (2) elemental residence, mineralogical and petrochemical characteristics; (3) mobilization and reaction pathways, transport, and fate of potentially toxic elements associated with the occurrence, development, and societal use of phosphate; (4) geophysical signatures; and (5) improving the understanding of deposit origin. Because raw data acquired during the project will require time to interpret, the data are released in open-file reports for prompt availability to other workers. Open-file reports associated with this series of studies are submitted to each of the Federal and industry cooperators for comment; however, the USGS is solely responsible for the data contained in the reports.

    This project examined the internal architecture of delta front sandstones at two locations within the Turonian-age Wall Creek Member of the Frontier Formation, in Wyoming. The project involved traditional outcrop field work integrated with core-data, and 2D and 3D ground penetrating radar (GPR) imaging from behind the outcrops. The fluid-flow engineering work, handled through a collaborative grant given to PI Chris White at LSU, focused on effects on fluid flow of late-stage calcite cement nodules in 3D. In addition to the extensive field component, the work funded 2 PhD students (Gani and Lee) and resulted in publication of 10 technical papers, 17 abstracts, and 4 internal field guides. PI Bhattacharya also funded an additional 3 PhD students that worked on the Wall Creek sandstone funded separately through an industrial consortium, two of whom graduated in the fall 2006 ((Sadeque and Vakarelov). These additional funds provided significant leverage to expand the work to include a regional stratigraphic synthesis of the Wall Creek Member of the Frontier Formation, in addition to the reservoir-scale studies that DOE directly funded. Awards given to PI Bhattacharya included the prestigious AAPG Distinguished Lecture Award, which involved a tour of about 25 Universities and Geological Societies in the US and Canada in the fall of 2005 and Spring of 2006. Bhattacharya gave two talks, one entitled “Applying Deltaic and Shallow Marine Outcrop Analogs to the Subsurface”, which highlighted the DOE sponsored work and the other titled “Martian River Deltas and the Origin of Life”. The outcrop analog talk was given at about 1/2 of the venues visited.

    The Tongue River Member of the Paleocene Fort Union Formation is an important coal-bearing sedimentary unit in the Powder River Basin of Wyoming and Montana. We studied the depositional environments of a portion of this member at three sites 20 km apart in the southeastern part of the basin. Six lithofacies are recognized that we assign to five depositional facies categorized as either channel or interchannel-wetlands environments. (1) Type A sandstone is cross stratified and occurs as lenticular bodies with concave-upward basal surfaces; these bodies are assigned to the channel facies interpreted to be the product of low-sinuosity streams. (2) Type B sandstone occurs in parallel-bedded units containing mudrock partings and fossil plant debris; these units constitute the levee facies. (3) Type C sandstone typically lacks internal structure and occurs as tabular bodies separating finer grained deposits; these bodies represent the crevasse-splay facies. (4) Gray mudrock is generally nonlaminated and contains ironstone concretions; these deposits constitute the floodplain facies. (5) Carbonaceous shale and coal are assigned to the swamp facies. We recognize two styles of stream deposition in our study area. Laterally continuous complexes of single and multistoried channel bodies occur at our middle study site and we interpret these to be the deposits of sandy braided stream systems. In the two adjacent study sites, single and multistoried channel bodies are isolated in a matrix of finer-grained interchannel sediment suggesting deposition by anastomosed streams. A depositional model for our study area contains northwest-trending braided stream systems. Avulsions of these systems created anastomosed streams that flowed into adjacent interchannel areas. We propose that during late Paleocene a broad alluvial plain existed on the southeastern flank of the Powder River Basin. The braided streams that crossed this surface were tributaries to a northward-flowing, basin

    Black, organic-rich rocks of the upper shale member of the Upper Devonian–Lower Mississippian Bakken Formation, a world-class petroleum source rock in the Williston Basin of the United States and Canada, contain a diverse suite of mudstone lithofacies that were deposited in distinct facies belts. The succession consists of three discrete facies associations (FAs). These comprise: 1) siliceous mudstones; 2) quartz- and carbonate-bearing, laminated mudstones; and 3) macrofossil-debris-bearing massive mudstones. These FAs were deposited in three facies belts that reflect proximal to distal relationships in this mudstone system. The macrofossil-debris-bearing massive mudstones (FA 3) occur in the proximal facies belt and contain erosion surfaces, some with overlying conodont and phosphate–lithoclast lag deposits, mudstones with abundant millimeter-scale siltstone laminae showing irregular lateral thickness changes, and shell debris. In the medial facies belt, quartz- and carbonate-bearing, laminated mudstones dominate, exhibiting sub-millimeter-thick siltstone layers with variable lateral thicknesses and localized mudstone ripples. In the distal siliceous mudstone facies belt, radiolarites, radiolarian-bearing mudstones, and quartz- and carbonate-bearing, laminated mudstones dominate. Overall, total organic carbon (TOC) contents range between about 3 and 10 wt %, with a general proximal to distal decrease in TOC content. Abundant evidence of bioturbation exists in all FAs, and the lithological and TOC variations are paralleled by changes in burrowing style and trace-fossil abundance. While two horizontal traces and two types of fecal strings are recognized in the proximal facies belt, only a single horizontal trace fossil and one type of fecal string characterize mudstones in the distal facies belt. Radiolarites intercalated into the most distal mudstones are devoid of traces and fecal strings. Bedload transport processes, likely caused by storm-induced turbidity

    The temperature at which shortite (Na2Ca2(CO3)3) forms from pirssonite (Na2Ca(CO3)2·2H2O) and calcite using pure synthetic phases in the system Na2CO3-CaCO3-H2O has been experimentally determined. At ˜1 atm pressure, shortite forms via the reaction Na2Ca(CO3)2·2H2O + CaCO3 = Na2Ca2(CO3)3 + 2H2O above 55 ± 2 °C. This equilibrium temperature is lower than determined previously (90 ± 25 °C) by Bradley and Eugster (1969). The solution in equilibrium with synthetic shortite, pirssonite, and calcite approximates a binary H2O-Na2CO3 brine with 1.1 m Na2CO3 (10.6 wt% Na2CO3). The equilibrium temperature is lowered to 52 ± 2 °C with 5 m NaCl added to the system, which shows that this reaction is weakly dependent on the activity of H2O, aO. This study suggests that shortite does not occur in surficial alkaline saline environments because temperatures are too low. Shortite is abundant in the Wilkins Peak Member (WPM) of the Eocene Green River Formation, Green River Basin, Wyoming, USA (>78 million tons/km2), where it occurs as diagenetic displacive crystals, fracture fills, and pseudomorphous replacements of a precursor Na-Ca-carbonate. The large area over which shortite occurs in the WPM indicates that saline pore fluids once existed in the buried lacustrine sediments, and thus, at times, large Na-CO3-rich saline alkaline lakes or laterally extensive saline groundwaters existed in the Green River Basin during WPM time. The thermal stability of shortite, together with vitrinite reflectance data and inferred regional geothermal gradients, establish that the shortite-bearing intervals of the WPM were buried to maximum depths of ˜1000 m in the Green River Basin, and since experienced ˜800 m of erosional exhumation.

  10. 3D Sedimentological and geophysical studies of clastic reservoir analogs: Facies architecture, reservoir properties, and flow behavior within delta front facies elements of the Cretaceous Wall Creek Member, Frontier Formation, Wyoming

    rock types (\\Eg sandstones and mudstones) and the variation of transport properties (\\Eg permeability and porosity) within bodies of a particular rock type. Both basin-wide processes such as sea-level change and the autocyclicity of deltaic processes commonly cause deltaic reservoirs to have large variability in rock properties; in particular, alternations between mudstones and sandstones may form baffles and trends in rock body permeability can influence productivity and recovery efficiency. In addition, diagenetic processes such as compaction, dissolution, and cementation can alter the spatial pattern of flow properties. A better understanding of these properties, and improved methods to model the properties and their effects, will allow improved reservoir development planning and increased recovery of oil and gas from deltaic reservoirs. Surface exposures of ancient deltaic rocks provide a high resolution, low uncertainty view of subsurface variability. Patterns and insights gleaned from these exposures can be used to model analogous reservoirs, for which data is much sparser. This approach is particularly attractive when reservoir formations are exposed at the surface. The Frontier Formation in central Wyoming provides an opportunity for high resolution characterization. The same rocks exposed in the vicinity of the Tisdale anticline are productive in nearby oil fields, including Salt Creek. Many kilometers of good-quality exposure are accessible, and the common bedding-plane exposures allow use of shallow-penetration, high-resolution electromagnetic methods known as ground-penetrating radar. This study combined geologic interpretations, maps, vertical sections, core data, and ground-penetrating radar to construct high-resolution geostatistical and flow models for the Wall Creek Member of the Frontier Formation. Stratal-conforming grids were use to reproduce the progradational and aggradational geometries observed in outcrop and radar data. A new, Bayesian method

    The Permian Phosphoria Formation of southeastern Idaho hosts one of the largest phosphate deposits in the world. Despite the economic significance of this Formation, the fine-grained nature of the phosphorite has discouraged detailed mineralogical characterization and quantification studies. Recently, selenium and other potentially toxic trace elements in mine wastes have drawn increased attention to this formation, and motivated additional study. This study uses powder X-ray diffraction (XRD), with Rietveld quantification software, to quantify and characterize the mineralogy of composite channel samples and individual samples collected from the stratigraphic sections measured by the U.S. Geological Survey in the Meade Peak Member of the Permian Phosphoria Formation at the Enoch Valley mine on Rasmussen Ridge, approximately 15 miles northeast of Soda Springs, Idaho.

    A tubular melt containment member for transient containment of molten metals and alloys, especially reactive metals and alloys, includes a melt-contacting layer or region that comprises an oxygen-deficient rare earth oxide material that is less reactive as compared to the counterpart stoichiometric rare earth oxide. The oxygen-deficient (sub-stoichiometric) rare earth oxide can comprise oxygen-deficient yttria represented by Y.sub.2O.sub.3-x wherein x is from 0.01 to 0.1. Use of the oxygen-deficient rare earth oxide as the melt-contacting layer or region material reduces reaction with the melt for a given melt temperature and melt contact time.

    Wikipedia is an online, free access, volunteer-contributed encyclopedia. This article focuses on the Wikipedians' (Wikipedia users) personality characteristics, studying Wikipedians' conceptions of Real-Me and BFI dimensions. To survey these aspects, we posted links to two online web questionnaires; one was targeted at Wikipedians and the second to non-Wikipedia users. One hundred and thirty-nine subjects participated in the study, of which 69 were active Wikipedia members. It was found that Wikipedia members locate their real me on the Internet more frequently as compared to non-Wikipedia members. Variance analysis revealed significant differences between Wikipedia members and non-Wikipedia members in agreeableness, openness, and conscientiousness, which were lower for the Wikipedia members. An interaction was found between Wikipedia membership and gender: introverted women were more likely to be Wikipedia members as compared with extroverted women. The results of this study are discussed with special emphasis on the understanding of the motivators of Wikipedia members.

    The composition, species abundances, and spatial and temporal distributions of mollusc assemblages were controlled by the environments in which they lived and the depositional processes that affected the molluscs after death and before final burial. Post-mortem transport, reworking and concentration of shells, and mixing of faunal elements from discrete habitats produced a taphonomic 'overprint' on assemblage characteristics that directly reflects the processes of alluvial plain and floodbasin lacustrine sedimentation. The 'overprint' can be interpreted from outcrop analysis of molluscan biofabric, which consists of: 1) orientation, fragmentation, size-sorting, abrasion, density, and dispersion of shells, 2) the nature and extent of shell-infilling, and 3) ratio of articulated to disarticulated bivalves. Taphonomic characteristics were used with sedimentological properties to differentiate in-place, reworked, transported, and ecologically mixed mollusc assemblages. This study also defines the paleoecology of habitat preferences of mollusc species as a basis for recognition of the environments in which these assemblages were deposited: 1) large floodbasin lakes, 2) small floodbasin lakes, and 3) crevasse deltas and splays. Integration of sedimentology and paleoecology provides an interdisciplinary approach to the interpretation of alluvial environments through time in the Tongue River Member. -Authors

  7. Cytochrome P450 family member CYP704B2 catalyzes the {omega}-hydroxylation of fatty acids and is required for anther cutin biosynthesis and pollen exine formation in rice.

    The anther cuticle and microspore exine act as protective barriers for the male gametophyte and pollen grain, but relatively little is known about the mechanisms underlying the biosynthesis of the monomers of which they are composed. We report here the isolation and characterization of a rice (Oryza sativa) male sterile mutant, cyp704B2, which exhibits a swollen sporophytic tapetal layer, aborted pollen grains without detectable exine, and undeveloped anther cuticle. In addition, chemical composition analysis indicated that cutin monomers were hardly detectable in the cyp704B2 anthers. These defects are caused by a mutation in a cytochrome P450 family gene, CYP704B2. The CYP704B2 transcript is specifically detected in the tapetum and the microspore from stage 8 of anther development to stage 10. Heterologous expression of CYP704B2 in yeast demonstrated that CYP704B2 catalyzes the production of omega -hydroxylated fatty acids with 16 and 18 carbon chains. Our results provide insights into the biosynthesis of the two biopolymers sporopollenin and cutin. Specifically, our study indicates that the omega -hydroxylation pathway of fatty acids relying on this ancient CYP704B family, conserved from moss to angiosperms, is essential for the formation of both cuticle and exine during plant male reproductive and spore development.

  8. Study of nsLTPs in Lotus japonicus genome reveal a specific epidermal cell member (LjLTP10) regulated by drought stress in aerial organs with a putative role in cutin formation.

    The cuticle is the first defense against pathogens and the second way water is lost in plants. Hydrophobic layers covering aerial plant organs from primary stages of development form cuticle, including major classes of aliphatic wax components and cutin. Extensive research has been conducted to understand cuticle formation mechanisms in plants. However, many questions remain unresolved in the transport of lipid components to form cuticle. Database studies of the Lotus japonicus genome have revealed the presence of 24 sequences classified as putative non-specific lipid transfer proteins (nsLTPs), which were classified in seven groups; four groups were selected because of their expression in aerial organs. LjLTP8 forms a cluster with DIR1 in Arabidopsis thaliana while LjLTP6, LjLTP9, and LjLTP10 were grouped as type I LTPs. In silico studies showed a high level of structural conservation, and substrate affinity studies revealed palmitoyl-CoA as the most likely ligand for these LTPs, although the Lyso-Myristoyl Phosphatidyl Choline, Lyso-myristoyl phosphatidyl glycerol, and Lyso-stearyl phosphatidyl choline ligands also showed a high affinity with the proteins. The LjLTP6 and LjLTP10 genes were expressed in both the stems and the leaves under normal conditions and were highly induced during drought stress. LjLTP10 was the most induced gene in shoots during drought. The gene was only expressed in the epidermal cells of stems, primordial leaves, and young leaflets. LjLTP10 was positively regulated by MeJA but repressed by abscisic acid (ABA), ethylene, and H2O2, while LjLTP6 was weakly induced by MeJA, repressed by H2O2, and not affected by ABA and ethylene. We suggest that LjLTP10 is involved in plant development of stem and leaf cuticle, but also in acclimation to tolerate drought stress in L. japonicus.

    Data are presented demonstrating that the life expectancy (LE) of kibbutz members--both men and women--is higher than that of the overall Jewish population in Israel. Closer inspection of the death rates at various ages reveals that, from age thirty, those of kibbutz women are lower than those of the Jewish population. Although those of kibbutz men are actually higher until age forty-nine, nevertheless the LE of kibbutz members (based on death rates) surpasses that of Jews in Israel. These data add to and support other research findings illustrating the more positive mental health and well-being found among kibbutz members than among other comparative populations. Similarly, the factors contributing to kibbutz members' life expectancy evolve from this quality of life, especially as this quality of life affects old age.

    Interventions to improve communication among family members may facilitate information flow about familial risk and preventive health behaviors. This is a secondary analysis of the effects of an interactive website intervention aimed at increasing communication frequency and agreement about health risk among melanoma families. Participants were family units, consisting of one family member with melanoma identified from a previous research study (the Case) and an additional first degree relative and a parent of a child 0-17. Family triads were randomized to receive access to the website intervention or to serve as control families. Family communication frequency and agreement about melanoma prevention behaviors and beliefs were measured at baseline and again at 1 year post randomization. Intervention participants of all three types significantly increased the frequency of communication to their first degree relatives (Parents, siblings, children; range = 14-18 percentage points; all p < .05). At baseline, approximately two-thirds of all three family members talked with at least some member of the family about cancer risk. Agreement between Cases and First Degree Relatives and between Cases and Parents increased from pre to post intervention in the intervention participants compared to the control participants (p < .05). These findings provide support for interventions to improve family communication about cancer risk.

    1999-08-01

    In aviation, it is essential that all aircrew members remain alert and contribute, by their observations and actions, to flight safety. Especially in helicopter operations, crewmembers riding in the rear of the aircraft play an integral role in many aspects of flight, such as take-offs, landings, turns, formation flights, hazard avoidance, situational awareness, military operations, and crew coordination. We present the case of a helicopter crew chief with idiopathic hypersomnia, briefly review the disorder, and give the recent U.S. military aviation experience with sleep disorders. Flight surgeons and aeromedical examiners should be active in considering and diagnosing sleep-related disorders as the aviator or crewmember may not be aware of the disease or may not volunteer the history. A directed history is important in making the diagnosis, as are reports from family and other aircrew members. Referral to a sleep specialist is required in performing objective sleep studies, establishing the diagnosis, recommending treatment, and providing a prognosis. Many sleep disorders are treatable and aeromedically waiverable.

    Heier, W. C. (Inventor)

    1974-01-01

    A laminate is obtained by providing a lightweight core material, such as a honeycombed plastic or metal, within the cavity defined by an annular mold cavity frame. Face sheets, which are to be bonded to the core material, are provided on opposite sides of the frame and extend over the frame, thus sealing the core material in the cavity. An adhesive is provided between the core material and the face sheets and the combined thickness of the core material and adhesive is a close fit within the opposed face sheets. A gas tight seal, such as an O-ring gasket, is provided between the frame and the face sheet members to form a gas tight cavity between the face sheet members and the frame. External heat and pressure are used to bond the face sheets to the core material. Gas pressure is introduced into the sealed cavity to minimize out-gasing of the adhesive.

  6. Origin of lacustrine rocks of Wilkins Peak Member, Wyoming

    SciTech Connect

    Sullivan, R.

    1985-06-01

    Wilkins Peak Member of the Green River Formation, with its interbeds of trona, oil shale, and dolomitic mudstone, contrasts markedly with the predominantly oilshale and calcitic mudstone sequences of the remainder of the succession. Much discussion has centered on the origin of these lacustrine rocks. A perennial meromictic (stratified) lake model has been replaced in recent years by a playa-lake model. The subsurface stratigraphy, however, was not well known when the models were developed. Paleogeographic reconstruction indicates that the region was subjected to variations in hydrographic conditions mainly in response to climatic fluctuations. During humid subtropical periods, widespread during the deposition of the Tipton Shale Member and Laney Member, the lakes were predominantly open meromictic systems with rivers entering the basin from the north. These environmental conditions were modified during deposition of the Wilkins Peak Member as the climate became more arid, and along the southern margin of the basin, shallow, saline-alkaline playa lakes formed in response to these changes. The widespread occurrence in the subsurface of fluvial clastic sequences of the Wasatch Formation associated with the Wilkins Peak Member would indicate that the playa lakes were frequently flooded and freshened by southern drainage systems. Therefore, the lakes were continuously undergoing modifications under the influence of climatic and possibly tectonic processes.

    2011-02-10

    The ionization energies (IEs) and heats of formation (ΔH°(f0)/ΔH°(f298)) for thiophene (C(4)H(4)S), furan (C(4)H(4)O), pyrrole (C(4)H(4)NH), 1,3-cyclopentadiene (C(4)H(4)CH(2)), and borole (C(4)H(4)BH) have been calculated by the wave function-based ab initio CCSD(T)/CBS approach, which involves the approximation to the complete basis set (CBS) limit at the coupled-cluster level with single and double excitations plus a quasi-perturbative triple excitation [CCSD(T)]. Where appropriate, the zero-point vibrational energy correction (ZPVE), the core-valence electronic correction (CV), and the scalar relativistic effect (SR) are included in these calculations. The respective CCSD(T)/CBS predictions for C(4)H(4)S, C(4)H(4)O, C(4)H(4)NH, and C(4)H(4)CH(2), being 8.888, 8.897, 8.222, and 8.582 eV, are in excellent agreement with the experimental values obtained from previous photoelectron and photoion measurements. The ΔH°(f0)/ΔH°(f298) values for the aforementioned molecules and their corresponding cations have also been predicted by the CCSD(T)/CBS method, and the results are compared with the available experimental data. The comparisons between the CCSD(T)/CBS predictions and the experimental values for C(4)H(4)S, C(4)H(4)O, C(4)H(4)NH, and C(4)H(4)CH(2) suggest that the CCSD(T)/CBS procedure is capable of predicting reliable IE values for five-membered-ring molecules with an uncertainty of ±13 meV. In view of the excellent agreements between the CCSD(T)/CBS predictions and the experimental values for C(4)H(4)S, C(4)H(4)O, C(4)H(4)NH, and C(4)H(4)CH(2), the similar CCSD(T)/CBS IE and ΔH°(f0)/ΔH°(f298) predictions for C(4)H(4)BH, whose thermochemical data are not readily available due to its reactive nature, should constitute a reliable data set. The CCSD(T)/CBS IE(C(4)H(4)BH) value is 8.868 eV, and ΔH°(f0)/ΔH°(f298) values for C(4)H(4)BH and C(4)H(4)BH(+) are 269.5/258.6 and 1125.1/1114.6 kJ/mol, respectively.

  16. SEALING MEANS FOR RELATIVELY ROTATABLE MEMBERS

    DOEpatents

    Skarstrom, C.S.

    1960-10-25

    A sealing means is offered for maintaining a seal between a pair of relatively rotatable members, panticularly between a rotating shaft and a stationary member surrounding the shaft. The sealing is accomplished by means of a flange extending outward radially on each of a plurality of sealing rings mounted on the rotating member which fit into annular grooves in the stationary member and are held in sealing relation therewith by means of spring rings. In addition, means are provided for passing a sealing gas through the seal sunfaces to prevent accumulation of lubricant and for scavenging any gas which may have leaked from the internal member into the seal area.

  17. An Unusually Shaped Haumea Family Member

    NASA Astrophysics Data System (ADS)

    Lacerda, P.; McNeill, A.

    2013-09-01

    2013 EL61 Haumea is a 2000 km-scale, fast-spinning Kuiper belt object covered in water ice, but with a bulk density near 2.5 g cm-3 implying a rocky interior (Rabinowitz et al. 2006; Trujillo et al. 2007). Approximately a dozen Kuiper belt objects (KBOs) have been identified as possibly related to Haumea as they share similar orbital properties and unusually fresh, icy surfaces similar to the mantle covering Haumea (Carry et al. 2012). These KBOs are usually referred to as the Haumea family. The formation of the family is the subject of intense speculation (Brown et al. 2007, Schlichting & Sari 2009, Leinhardt et al. 2010). Sparse photometry of one of the family members, 2003 SQ317, revealed an interesting high photometric variability (Snodgrass et al. 2009). We followed up on those observation and used the NTT in La Silla to obtain dense, time-resolved photometry of SQ317 over two semesters. Analysis of the lightcurve (Fig. 1) indicates a spin period P = 7.2 hr and a photometric range m = 0.9 mag. We will present implications of this lightcurve to the object's shape and bulk density.

  2. Flexible formation configuration for terrain following flight: Formation keeping constraints

    NASA Astrophysics Data System (ADS)

    Latyshev, Simon

    This work suggests a control method for the terrain-following formation motion of a group of communicating autonomous agents. The presented approach centers on defining a suitable set of constraints for formation keeping task that shall be fulfilled while agents are negotiating an unknown terrain toward the predefined goal location. It allows agents to maintain a general geometric formation shape, while allowing each individual formation member freedom of maneuver, required for terrain collision free motion. Formation structure is defined with the use of virtual leader. Formation keeping constraints are defined with plane surfaces, specified relative to position and navigation vector of the virtual leader. Formation navigation and guidance constraints are defined using navigation vectors of formation members and the virtual leader. Alternative designs for the constraints derived with parabolic, cone, and cylindrical surfaces are considered. Formation control is derived using the Udwadia-Kalaba equation, following corresponding approach to the development of control methods for constraint based dynamical systems, including leader-follower systems defined using geometric constraints. Approach to terrain following motion requiring agents to stay within bounds of cylindrical corridor volumes built around their respective navigation vectors is assumed. Individual formation primitives and multi-level, hierarchical, formation structures are considered. Simulations, based on three degrees of freedom nonlinear model of an agent, performed using Mathematica and specifically developed combined Maya-Mathematica modeling and simulation system, demonstrate that a flexible terrain following formation motion is achieved with the presented sets of constraints.

  3. Stress concentration factors for dented tubular members

    SciTech Connect

    Buitrago, J.; Hsu, T.M.

    1996-12-31

    This paper presents results of a finite element (FE) study conducted on /tubular members with dents of various geometries, including dents with circular and elliptical cross-sectional shapes. The modeling and analysis procedures are discussed, and stress concentration factors (SCFs) are generated for axial and bending loads in the member. Equations that give SCFs as function of the member size and dent geometry are developed for both load conditions. Then, simplified equations are proposed for structural assessment purposes.

  4. Converting virtual community members into online buyers.

    2010-10-01

    Although many online vendors have sponsored virtual communities (VCs) in the hope of reaping commercial benefits from it, not many have been successful in reaping commercial benefits from their VC. Online vendors can benefit greatly from having a VC, if the VC members can be converted into online buyers. This study examines the conversion of a VC member into an online buyer. Using a classical-conditioning approach, this study finds that members' committed participation in the VC is the springboard for online vendors to convert VC members into online buyers.

  13. Elastomeric member for energy storage device

    DOEpatents

    Hoppie, Lyle O.; Chute, Richard

    1985-01-01

    An energy storage device (10) is disclosed consisting of a stretched elongated elastomeric member (16), disposed within a tubular housing (14), which elastomeric member (16) is adapted to be torsionally stressed to store energy. The elastomeric member (16) is configured in the relaxed state with a uniform diameter body section, transition end sections, and is attached to rigid end piece assemblies (22, 24) of a lesser diameter. The profile and deflection characteristic of the transition sections (76, 78) are such that upon stretching of the member, a substantially uniform diameter assembly results to minimize the required volume of the surrounding housing (14). During manufacture, woven wire mesh sleeves (26, 28) are forced against a forming surface and bonded to the associated transition section (76, 78) to provide the correct profile and helix angle. Each sleeve (26, 28) contracts with the contraction of the associated transition section to maintain the bond therebetween.

    1975-10-28

    Methods and apparatus for fabrication of composite ceramic members having particular application for measuring oxygen activities in liquid sodium are described. The method involves the simultaneous deposition of ThO$sub 2$: 15 percent Y$sub 2$O$sub 3$ on a sintered stabilized zirconia member by decomposition of gaseous ThCl$sub 4$ and YCl$sub 3$ and by reacting with oxygen gas. Means are provided for establishing an electrical potential gradient across the zirconia member whereby oxygen ions, from a source on one side of the member portion to be coated, are migrated to the opposite side where a reaction and said decomposition and deposition are effected.

  16. Conducting a multi family member interview study.

    PubMed

    Reczek, Corinne

    2014-06-01

    Family researchers have long recognized the utility of incorporating interview data from multiple family members. Yet, relatively few contemporary scholars utilize such an approach due to methodological underdevelopment. This article contributes to family scholarship by providing a roadmap for developing and executing in-depth interview studies that include more than one family member. Specifically, it outlines the epistemological frames that most commonly underlie this approach, illustrates thematic research questions that it best addresses, and critically reviews the best methodological practices of conducting research with this approach. The three most common approaches are addressed in depth: separate interviews with each family member, dyadic or group interviews with multiple family members, and a combined approach that uses separate and dyadic or group interviews. This article speaks to family scholars who are at the beginning stages of their research project but are unsure of the best qualitative approach to answer a given research question.

    Braverman, J.I.; Miller, C.A.; Ellingwood, B.R.; Naus, D.J.; Hofmayer, C.H.; Bezler, P.; Chang, T.Y.

    2001-03-22

    This paper describes the results of a study to evaluate, in probabilistic terms, the effects of age-related degradation on the structural performance of reinforced concrete members at nuclear power plants. The paper focuses on degradation of reinforced concrete flexural members and shear walls due to the loss of steel reinforcing area and loss of concrete area (cracking/spalling). Loss of steel area is typically caused by corrosion while cracking and spalling can be caused by corrosion of reinforcing steel, freeze-thaw, or aggressive chemical attack. Structural performance in the presence of uncertainties is depicted by a fragility (or conditional probability of failure). The effects of degradation on the fragility of reinforced concrete members are calculated to assess the potential significance of various levels of degradation. The fragility modeling procedures applied to degraded concrete members can be used to assess the effects of degradation on plant risk and can lead to the development of probability-based degradation acceptance limits.

  1. 2004 NAI-ADP Deep Diamond Drill Cores: Transects Through Archean Time in the Pilbara Craton, Australia

    NASA Astrophysics Data System (ADS)

    Buick, R.; Dunlop, J. S.; Bonser, L. C.

    2004-12-01

    In July-August 2004, the NASA Astrobiology Drilling Program sponsored the coring of 3 deep diamond-drill holes in the Pilbara Craton of northwest Australia. The holes targeted the lowest grade and least deformed sedimentary sections of 4 stratigraphic units: the 2.4-2.6 Ga Hamersley Group, the 2.7 Ga Tumbiana Formation of the Fortescue Group, the 3.4 Ga Warrawoona Group, and the 3.5 Ga Coonterunah Group. ABDP 8 cored the unconformity between the Warrawoona and Coonterunah Groups to a depth of 330 metres, intersecting it at 155 metres. Because of syn-depositional erosion, the Strelley Pool Chert was attenuated and the alteration zone beneath the unconformity was scoured and filled to a depth of 10 metres by quartz arenite. As a result, no definitive lithological determination on its status as a potential paleosol could be made. Secondary oxidative alteration was present in Coonterunah cherts to depths of at least 220 metres down-hole. ABDP 9 cored 984 metres of the lower Hamersley Group, from the Dales Gorge Member of the Brockman Iron Formation into the Paraburdoo Member of the Wittenoom Formation. Though the hole was intended to penetrate the uppermost Fortescue Group, drilling was terminated early because of equipment damage by fractured rock, loss of water circulation clogging the hole with cuttings and unanticipated thickening of the Paraburdoo Member by dilational fracturing, expansive brecciation and cavity formation. 79 samples for organic geochemical analysis of biomarker syngenesis were collected under clean conditions immediately the core surfaced. A horizon of impact spherules was intersected in the Bee Gorge Member of the Wittenoom Formation; unlike surface exposures, it was markedly silicified and chloritized in drill-core. ABDP 10 cored 210 metres of the Tumbiana Formation, intersecting the entire Meentheena Carbonate Member, the upper Mingah Tuff Member and terminating just below 4 scoriaceous basalt flows.

  1. LIKELY MEMBERS OF THE {beta} PICTORIS AND AB DORADUS MOVING GROUPS IN THE NORTH

    SciTech Connect

    Schlieder, Joshua E.; Lepine, Sebastien; Simon, Michal E-mail: michal.simon@stonybrook.edu

    2012-10-01

    We present first results from follow-up of targets in the northern hemisphere {beta} Pictoris and AB Doradus moving group candidate list of Schlieder et al. We obtained high-resolution, near-infrared spectra of 27 candidate members to measure their radial velocities and confirm consistent group kinematics. We identify 15 candidates with consistent predicted and measured radial velocities, perform analyses of their six-dimensional (UVWXYZ) Galactic kinematics, and compare to known group member distributions. Based on these analyses, we propose that seven {beta} Pic and eight AB Dor candidates are likely new group members. Four of the likely new {beta} Pic stars are binaries, one a double-lined spectroscopic system. Three of the proposed AB Dor stars are binaries. Counting all binary components, we propose 22 likely members of these young, moving groups. The majority of the proposed members are M2 to M5 dwarfs, the earliest being of type K2. We also present preliminary parameters for the two new spectroscopic binaries identified in the data, the proposed {beta} Pic member and a rejected {beta} Pic candidate. Our candidate selection and follow-up has thus far identified more than 40 low-mass, likely members of these two moving groups. These stars provide a new sample of nearby, young targets for studies of local star formation, disks and exoplanets via direct imaging, and astrophysics in the low-mass regime.

  6. Lay REC members: patient or public?

    PubMed

    Staley, Kristina

    2013-12-01

    In practice, the role of lay members of research ethics committees (RECs) often involves checking the accessibility of written materials, checking that the practical needs of participants have been considered and ensuring that a lay summary of the research will be produced. In this brief report, I argue that all these tasks would be more effectively carried out through a process of patient involvement (PI) in research projects prior to ethical review. Involving patients with direct experience of the topic under investigation brings added value beyond the contributions typically made by lay REC members, who are often not patients themselves. This is because PI tailors the design and conduct of research to the specific interests and concerns of the people who will actually take part in a project and make use of its findings. If a project has PI in its early stages, then a similar input from lay REC members could at best result in duplication of effort and at worst create the potential for conflict. The rationale for lay REC membership will therefore need to change from 'contributing a patient perspective' to 'ensuring transparency and public accountability in REC decisions'. This has implications for addressing more strategic questions about lay REC membership, including who is best recruited to the role and how they should be expected to contribute in practice.

  18. Finland Becomes Eleventh ESO Member State

    NASA Astrophysics Data System (ADS)

    2004-07-01

    Finland has become the eleventh member state of the European Southern Observatory (ESO) [1]. The formal accession procedure was carried through as planned and has now been completed. Following the signing of the corresponding Agreement earlier this year (ESO PR 02/04), acceptance by the Finnish Parliament and ratification by the Finnish President of the Agreement as well as the ESO Convention and the associated protocols in June [2] and the deposit of the instruments of accession today, Finland has now officially joined ESO. ESO warmly welcomes the new member country and its scientific community that is renowned for their expertise in many frontline areas. The related opportunities will contribute to strenghtening of pioneering research with the powerful facilities at ESO's observatories, to the benefit of Astronomy and Astrophysics as well as European science in general. ESO also looks forward to collaboration with the Finnish high-tech industry. For Finland, the membership in ESO is motivated by scientific and technological objectives as well as by the objective of improving the public understanding of science. The Finnish Government is committed to increasing the public research funding in order to improve the quality, impact and internationalisation of research. Membership in ESO offers unique facilities for astronomical research which would not otherwise be available for Finnish astronomers. Finland is also very interested in taking part in technological development projects in fields like ICT, optics and instrumentation. For young scientists and engineers, ESO is a challenging, international working and learning environment. Finland has already taken part in the educational programmes of ESO, and as a member this activity will be broadened and intensified. In Finland there are also several science journalists and a large community of amateur astronomers who will be very happy to take part in ESO's outreach activities.

  19. Chromosomal aberrations in ISS crew members

    NASA Astrophysics Data System (ADS)

    Johannes, Christian; Goedecke, Wolfgang; Antonopoulos, Alexandra

    2012-07-01

    High energy radiation is a major risk factor in manned space missions. Astronauts and cosmonauts are exposed to ionising radiations of cosmic and solar origin, while on the Earth's surface people are well protected by the atmosphere and a deflecting magnetic field. There are now data available describing the dose and the quality of ionising radiation on-board of the International Space Station (ISS). Nonetheless, the effect of increased radiation dose on mutation rates of ISS crew members are hard to predict. Therefore, direct measurements of mutation rates are required in order to better estimate the radiation risk for longer duration missions. The analysis of chromosomal aberrations in peripheral blood lymphocytes is a well established method to measure radiation-induced mutations. We present data of chromosome aberration analyses from lymphocyte metaphase spreads of ISS crew members participating in short term (10-14 days) or long term (around 6 months) missions. From each subject we received two blood samples. The first sample was drawn about 10 days before launch and a second one within 3 days after return from flight. From lymphocyte cultures metaphase plates were prepared on glass slides. Giemsa stained and in situ hybridised metaphases were scored for chromosome changes in pre-flight and post-flight blood samples and the mutation rates were compared. Results obtained in chromosomal studies on long-term flight crew members showed pronounced inter-individual differences in the response to elevated radiation levels. Overall slight but significant elevations of typical radiation induced aberrations, i.e., dicentric chromosomes and reciprocal translocations have been observed. Our data indicate no elevation of mutation rates due to short term stays on-board the ISS.

    2016-01-01

    Young moving groups (YMGs) are coeval, comoving groups of stars which have migrated from their birthsites after formation. In the substellar regime, YMG members are key benchmarks to empirically define brown dwarf evolution with age and to study the lowest mass end of the initial mass function. We have combined Pan-STARRS1 (PS1) proper motions with optical+IR photometry from PS1, 2MASS and WISE to perform a large-scale (~30,000 deg2) systematic search for substellar members down to ~10 MJup . We have obtained near-IR spectroscopy of a large sample of ultracool candidate YMG members to assess their youth via gravity-sensitive absorption features. We have identified several new intermediate-gravity candidate members of the AB Dor Moving Group, potentially greatly expanding the substellar membership. These new candidate members bridge the gap between the known low-mass stellar and planetary-mass members and yield valuable insight into the spectral characteristics of young brown dwarfs.

  3. The dying child and surviving family members.

    Shrier, D K

    1980-12-01

    This overview of death and dying focuses on the dying child and surviving family members. Children's concepts of death at different developmental stages are reviewed. These range from an inability to distinguish death from other forms of separation prior to age 3, through partial concepts of death until, by age 10 to 15 years, children are able to conceptualize death as universal, inevitable and final. The importance of adults assisting in the child's growing comprehension of death is stressed. The stages of grief and mourning, as outlined by Kubler-Ross, are reviewed from the perspective of the child and family: denial, anger, bargaining, depression and acceptance. Recognition is given to the variations in coping styles among different family members. The special circumstances related to the death of an infant and the impact of the death of a child on the surviving siblings are discussed. Specific helpful interventions to assist families in coping with mourning are described. The death of a child remains one of the most painful and difficult events for a family and its physician to accept.

  4. Orienting members in a preselected rotary alignment

    Williams, Ray E.

    1987-01-01

    An apparatus for orienting members and for maintaining their rotary alignment during orienting members. The apparatus comprises first and second cylindrical elements, a rotation prevention element, a collar and a retainer. Each element has an outside wall, and first and second ends, each end having an outside edge. The first element has portions defining a first plurality of notches located at the outside edge of its first end. An external threaded portion is on the outside wall of the first element and next to the first plurality of notches. The second element has portions defining a second plurality of notches located at the outside edge of its first end. The first plurality has a different number than the second plurality. The first ends of the first and second tubes have substantially the same outside diameter and are abutted during connection so that a cavity is formed whenever first and second tube notches substantially overlap. A rotation prevention element is placed in the cavity to prevent rotation of the first and second elements. A collar with an internal threaded portion is slidably disposed about the second element. The internal threaded portion engages the external threaded portion of the first element to connect the elements. A lip connected to the collar prevents separation of the collar from the second element.

    Dovichi, Norman J.; Zhang, Jian Z.

    1996-01-01

    A multiple capillary biochemical analyzer for sequencing DNA and performing other analyses, in which a set of capillaries extends from wells in a microtiter plate into a cuvette. In the cuvette the capillaries are held on fixed closely spaced centers by passing through a sandwich construction having a pair of metal shims which squeeze between them a rubber gasket, forming a leak proof seal for an interior chamber in which the capillary ends are positioned. Sheath fluid enters the chamber and entrains filament sample streams from the capillaries. The filament sample streams, and sheath fluid, flow through aligned holes in a barrier member spaced close to the capillary ends, into a collection chamber having a lower glass window. The filament streams are illuminated above the barrier member by a laser, causing them to fluoresce. The fluorescence is viewed end-on by a CCD camera chip located below the glass window. The arrangement ensures an equal optical path length from all fluorescing spots to the CCD chip and also blocks scattered fluorescence illumination, providing more uniform results and an improved signal to noise ratio.

    2016-01-01

    Objectives The purpose of this study was to evaluate the quality of life (QOL) in postmenopausal members and non-members of the elderly support association in Borujen city, Iran. Methods This study was a cross-sectional descriptive study being applied to the participants were postmenopausal women of over 55 years. Thus, 40 postmenopausal members of the elderly support association of Borujen city and 40 non-members were randomly selected. The 36 item short-form health survey (SF-36), with the 4 psychological, social, physical-movement, and environmental domains, was completed. Data were analyzed using SPSS software. Results The mean total score of QOL of member of the association was significantly greater than non-members. Student's t-test showed a significant relationship between QOL and membership of the association (P < 0.05). One-way analysis of variance (ANOVA) showed that the mean QOL of postmenopausal women, according to membership and marital status (P < 0.01), housing (P < 0.01), and underlying disease (P < 0.01), was statistically significant. Conclusions According to the results, supportive measures, such as increasing the participation of the elderly in public life through proper preparations to join them and membership in peer groups such as support associations and non-governmental organizations (NGOs) can be greatly effective in improving QOL. The results showed that the QOL of the participants was at a moderate level and membership in support associations for the elderly was effected on the QOL in postmenopausal women. Moreover, considering the importance of the elderly in the community. PMID:28119895

    2017-03-01

    Researchers using an achievement goal theory and caring climate framework have highlighted the connection between fitness center members' climate perceptions and their exercise motivation. However, much of what is known comes from current members, with little known about former and non-members' perceptions. The purpose of this study was to compare current, former, and non-members' perceptions of the motivational climate of a university campus fitness facility. Faculty and staff ( N = 657) at a large American university completed a one-time mixed-methods survey about their perceptions of the motivational climate (i.e. caring climate; preference for caring, task-, ego-involving climate), staff behaviors (i.e. caring, task involving), and usage of their campus fitness facility. Despite usage, quantitative analyses indicated that all participants reported valuing a caring, task-involving climate over a non-caring, ego-involving climate when choosing a fitness center. When asked about the particular fitness center for this study, current members were more likely than former and never users to perceive a caring climate where staff engaged in task-involving behaviors. Content analysis of the qualitative comments revealed that three main themes emerged with regard to perceptions and fell into positive, negative, and neutral categories. Overall, current users were more likely to perceive caring behaviors among the staff such as taking measures to welcome members and supporting their individualized goals. Former and never users were more likely to perceive staff as unhelpful, unwelcoming, and unfriendly. In an effort to remove barriers to physical activity, fitness professionals should consider how their behaviors, interactions, and promotional materials impact individuals' decision of whether to exercise at their fitness facility. The findings include a discussion for fitness staff to consider when creating advertisement and outreach efforts as well as how to foster the

    Defining optimal nutrient requirements is imperative to ensure crew health on long-duration space exploration missions. To date, nutrient requirement data have been extremely limited because of small sample sizes and difficulties associated with collecting biological samples. In this study, we examined changes in body composition, bone metabolism, hematology, general blood chemistry, and blood levels of selected vitamins and minerals after long-duration (128-195 d) space flight aboard the International Space Station. Crew members consumed an average of 80% of the recommended energy intakes, and on landing day their body weight had decreased (P=0.051). After flight, hematocrit was less, and serum femtin was greater than before flight (P<0.01). Serum iron, ferritin saturation, and transferrin had decreased after flight. The finding that other acute-phase proteins, including ceruloplasmin, retinol binding protein, transthyretin, and albumin were not changed after flight suggests that the changes in iron metabolism may not be strictly due to an inflammatory response. Urinary 8- hydroxy-2'-deoxyguanosine concentration was greater and superoxide dismutase was less after flight, indicating that oxidative damage had increased (P<0.05). Despite the reported use of vitamin D supplements during flight, serum 25-hydroxyvitamin D was significantly decreased after flight (P<0.01). Bone resorption was increased after flight, as indicated by several urinary markers of bone resorption. Bone formation, assessed by serum concentration of bone-specific alkaline phosphatase, was elevated only in crew members who landed in Russia, probably because of the longer time lapse between landing and sample collection. These data provide evidence that bone loss, compromised vitamin D status, and oxidative damage remain critical concerns for long-duration space flight.

  14. Grief elaboration in families with handicapped member.

    1992-01-01

    Families with handicapped member seem to follow the same five stages (rejection and isolation, anger, dealing with the problem, depression, acceptance) of Kubler-Ross grief elaboration theory while dealing with the narcissistic wound of a handicapped child. Some of these families show a block in one of the stages. The effort of psychotherapy is to remove the block and let them reach the last stage. In this paper families under systemic psychotherapeutic treatment are analyzed, who had in common the birth of a child with low or modest invalidating signs and psychotic or autistic features. The families structure did not show the characteristics of a psychotic family. Nevertheless either one or both parents ignored the evidence of their child disease and they built a "disease-incongrous" wait around the child, trying to push away the painful reality. The authors explain the importance of this approach for the improvement of the autistic traits.

It will foster this discipline on the highest quality level and open new opportunities for Czech industry to actively cooperate in research and development of high-tech instruments for astronomical research," said Miroslava Kopicová, Minister of Education, Youth and Sports of the Czech Republic. ESO PR Photo 52/06 ESO PR Photo 52/06 Signing Ceremony "We warmly welcome the Czech Republic as the thirteenth member of ESO," said Catherine Cesarsky, ESO's Director General. "The timing couldn't be better chosen: with the Very Large Telescope, Europe is now at the forefront of ground-based astronomy, and with the construction of ALMA and the final studies for the European Extremely Large Telescope, we will ensure that this will remain so for several decades. We look forward to working together with our Czech colleagues towards these successes." The signing event took place at the Czech Ministry of Education, Youth and Sports in Prague. Following ratification by the Czech Parliament, the Czech Republic with thus join the twelve present member states of ESO, the European Organisation for Astronomical Research in the Southern Hemisphere: Belgium, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom. The Czech Republic is the first country from Central and Eastern Europe to join ESO. Astronomy in the Czech Republic has a very long tradition that dates from as far back as 3500 BC. Four centuries ago, Tycho Brahe and Johannes Kepler established themselves in Prague at the invitation of the emperor Rudolph II, laying the ground for the first golden age in astronomy.

    When will children decide to help outgroup peers? We examined how intergroup competition, social perspective taking (SPT), and empathy influence children's (5-10 years, N = 287) prosocial intentions towards outgroup members. Study 1 showed that, in a minimal group situation, prosociality was lower in an intergroup competitive than in a non-competitive or interpersonal context. Study 2 revealed that, in a real groups situation involving intergroup competition, prosociality was associated with higher empathy and lower competitive motivation. In a subsequent non-competitive context, there were age differences in the impact of SPT and competitive motivation. With age, relationships strengthened between SPT and prosociality (positively) and between competitiveness and prosociality (negatively). Among older children, there was a carry-over effect whereby feelings of intergroup competitiveness aroused by the intergroup competitive context suppressed outgroup prosociality in the following non-competitive context. Theoretical and practical implications for improving children's intergroup relationships are discussed.

  19. Modelling crash propensity of carshare members.

    2014-09-01

    Carshare systems are considered a promising solution for sustainable development of cities. To promote carsharing it is imperative to make them cost effective, which includes reduction in costs associated to crashes and insurance. To achieve this goal, it is important to characterize carshare users involved in crashes and understand factors that can explain at-fault and not-at fault drivers. This study utilizes data from GoGet carshare users in Sydney, Australia. Based on this study it was found that carshare users who utilize cars less frequently, own one or more cars, have less number of accidents in the past ten years, have chosen a higher insurance excess and have had a license for a longer period of time are less likely to be involved in a crash. However, if a crash occurs, carshare users not needing a car on the weekend, driving less than 1000km in the last year, rarely using a car and having an Australian license increases the likelihood to be at-fault. Since the dataset contained information about all members as well as not-at-fault drivers, it provided a unique opportunity to explore some aspects of quasi-induced exposure. The results indicate systematic differences in the distribution between the not-at-fault drivers and the carshare members based on the kilometres driven last year, main mode of travel, car ownership status and how often the car is needed. Finally, based on this study it is recommended that creating an incentive structure based on training and experience (based on kilometres driven), possibly tagged to the insurance excess could improve safety, and reduce costs associated to crashes for carshare systems.

  20. Personality and community prevention teams: Dimensions of team leader and member personality predicting team functioning.

    2008-11-01

    The predictors and correlates of positive functioning among community prevention teams have been examined in a number of research studies; however, the role of personality has been neglected. In this study, we examined whether team member and leader personality dimensions assessed at the time of team formation predicted local prevention team functioning 2.5-3.5 years later. Participants were 159 prevention team members in 14 communities participating in the PROSPER study of prevention program dissemination. Three aspects of personality, aggregated at the team level, were examined as predictors: Openness to Experience, Conscientiousness, and Agreeableness. A series of multivariate regression analyses were performed that accounted for the interdependency of five categories of team functioning. Results showed that average team member Openness was negatively, and Conscientiousness was positively linked to team functioning. The findings have implications for decisions about the level and nature of technical assistance support provided to community prevention teams.

  1. Galaxy formation

    SciTech Connect

    Implications of the isotropy of the cosmic microwave background on large and small angular scales for galaxy formation are reviewed. In primeval adiabatic fluctuations, a universe dominated by cold, weakly interacting nonbaryonic matter, e.g., the massive photino is postulated. A possible signature of photino annihilation in our galactic halo involves production of cosmic ray antiprotons. If the density is near its closure value, it is necessary to invoke a biasing mechanism for suppressing galaxy formation throughout most of the universe in order to reconcile the dark matter density with the lower astronomical determinations of the mean cosmological density. A mechanism utilizing the onset of primordial massive star formation to strip gaseous protogalaxies is described. Only the densest, early collapsing systems form luminous galaxies. (ESA)

  2. Comet formation

    NASA Astrophysics Data System (ADS)

    Blum, J.

    2014-07-01

    There has been vast progress in our understanding of planetesimal formation over the past decades, owing to a number of laboratory experiments as well as to refined models of dust and ice agglomeration in protoplanetary disks. Coagulation rapidly forms cm-sized ''pebbles'' by direct sticking in collisions at low velocities (Güttler et al. 2010; Zsom et al. 2010). For the further growth, two model approaches are currently being discussed: (1) Local concentration of pebbles in nebular instabilities until gravitational instability occurs (Johansen et al. 2007). (2) A competition between fragmentation and mass transfer in collisions among the dusty bodies, in which a few ''lucky winners'' make it to planetesimal sizes (Windmark et al. 2012a,b; Garaud et al. 2013). Predictions of the physical properties of the resulting bodies in both models allow a distinction of the two formation scenarios of planetesimals. In particular, the tensile strength (i.e, the inner cohesion) of the planetesimals differ widely between the two models (Skorov & Blum 2012; Blum et al. 2014). While model (1) predicts tensile strengths on the order of ˜ 1 Pa, model (2) results in rather compactified dusty bodies with tensile strengths in the kPa regime. If comets are km-sized survivors of the planetesimal-formation era, they should in principle hold the secret of their formation process. Water ice is the prime volatile responsible for the activity of comets. Thermophysical models of the heat and mass transport close to the comet-nucleus surface predict water-ice sublimation temperatures that relate to maximum sublimation pressures well below the kPa regime predicted for formation scenario (2). Model (1), however, is in agreement with the observed dust and gas activity of comets. Thus, a formation scenario for cometesimals involving gravitational instability is favored (Blum et al. 2014).

    NASA Technical Reports Server (NTRS)

    Webster, M. S.; Fanson, J. L.; Lurie, B. J.; O'Brien, J. F.

    1992-01-01

    This paper describes the development and implementation of an active member in a precision truss structure. The active member utilizes a piezoelectric actuator motor imbedded in a steel case with built-in displacement sensor. This active member is used in structural quieting. Collocated active damping control loops are designed in order to impedance match piezoelectric active members to the structure. Results from application of these controllers and actuators to the JPL Phase B testbed are given.

  18. Confirmation and characterization of low-mass and brown dwarf candidate members of nearby young associations

    Young nearby associations provide a crucial sample of stars for studying the local star formation history, investigating the early phases of planet formation, and searching for exoplanets through direct imaging. While new associations have been identified in the last decade, their members are mostly restricted to relatively massive (F,G,K) stars. Through a novel statistical analysis, we have identified 357 highly probable young low-mass and brown dwarfs members of BetaPictoris and ABDoradus moving groups, TWHydrae, Tucana-Horologium, Columba, Carina and Argus associations. A confirmation of their membership and their young age require, however, measurements of their radial velocity, parallax and spectroscopic age indicators. First, we propose to use Phoenix to measure radial velocity for 40 northern candidates. Previous time allocations have already enabled the confirmation of 39 new members. Second, we propose to confirm the kinematic age of 15 candidates by using Chiron to measure several spectroscopic youth indicators, such as CaH, lithium, Halpha and HeI line (accretion) and rotation. Finally, we proposed to continue our trigonometric parallax program, initiated in 2011, to measure precisely the fourth astrometric epoch of 19 candidates. Our program will significantly improve the census of young moving group members.

  1. Characterisation of candidate members of (136108) Haumea's family. II. Follow-up observations

    Carry, B.; Snodgrass, C.; Lacerda, P.; Hainaut, O.; Dumas, C.

    2012-08-01

    Context. From a dynamical analysis of the orbital elements of trans-Neptunian objects (TNOs), Ragozzine & Brown (2007, AJ, 134, 2160) reported a list of candidate members of the first collisional family found among this population, associated with (136 108) Haumea (a.k.a. 2003 EL61). Aims: We aim to distinguish the true members of the Haumea collisional family from interlopers. We search for water ice on their surfaces, which is a common characteristic of the known family members. The properties of the confirmed family are used to constrain the formation mechanism of Haumea, its satellites, and its family. Methods: Optical and near-infrared photometry is used to identify water ice. We use in particular the CH4 filter of the Hawk-I instrument at the European Southern Observatory Very Large Telescope as a short H-band (HS), the (J - HS) colour being a sensitive measure of the water ice absorption band at 1.6 μm. Results: Continuing our previous study headed by Snodgrass, we report colours for 8 candidate family members, including near-infrared colours for 5. We confirm one object as a genuine member of the collisional family (2003 UZ117), and reject 5 others. The lack of infrared data for the two remaining objects prevent any conclusion from being drawn. The total number of rejected members is therefore 17. The 11 confirmed members represent only a third of the 36 candidates.

  17. Why does ingroup essentialism increase prejudice against minority members?

    PubMed

    Zagefka, Hanna; Nigbur, Dennis; Gonzalez, Roberto; Tip, Linda

    2013-01-01

    A study with British participants (N = 90) tested a potential mediator of the effect of essentialist beliefs about the national ingroup on prejudice against immigrants. Essentialist beliefs were defined as beliefs in genetic determinism, a basic assumption that group membership is "written in the blood" and that the groups' boundaries and characteristics are determined by genetic and/or biological factors. Essentialist beliefs were expected to play an important role in the formation of prejudice. They were predicted to be associated with a reduction in the perceived possibility of immigrants' adopting the mainstream culture. Further, it was expected that essentialist beliefs would be positively associated with perceptions of intergroup threat, which in turn would be associated with a stronger demand for immigrants adopting the mainstream culture. Taken together, essentialist beliefs were predicted to be associated with a greater discrepancy between the demand for and perceived feasibility of culture adoption. This discrepancy was hypothesized to mediate the effect of essentialist beliefs on prejudice against immigrants. Structural equation modeling analysis and mediation analysis supported the hypotheses, showing that essentialism attributed to the national ingroup results in people demanding something seemingly impossible from immigrants, and that this situation in which immigrants have little chance of fulfilling majority members' expectations results in prejudice against them. Thus, results show that perceptions of the ingroup are associated with attitudes to the outgroup, and they outline an explanatory mechanism for the positive correlation between essentialism and prejudice which has been found in previous research. Theoretical and applied implications are discussed.

  18. Cloud Formation

    NASA Astrophysics Data System (ADS)

    Graham, Mark Talmage

    2004-05-01

    Cloud formation is crucial to the heritage of modern physics, and there is a rich literature on this important topic. In 1927, Charles T.R. Wilson was awarded the Nobel Prize in physics for applications of the cloud chamber.2 Wilson was inspired to study cloud formation after working at a meteorological observatory on top of the highest mountain in Scotland, Ben Nevis, and testified near the end of his life, "The whole of my scientific work undoubtedly developed from the experiments I was led to make by what I saw during my fortnight on Ben Nevis in September 1894."3 To form clouds, Wilson used the sudden expansion of humid air.4 Any structure the cloud may have is spoiled by turbulence in the sudden expansion, but in 1912 Wilson got ion tracks to show up by using strobe photography of the chamber immediately upon expansion.5 In the interim, Millikan's study in 1909 of the formation of cloud droplets around individual ions was the first in which the electron charge was isolated. This study led to his famous oil drop experiment.6 To Millikan, as to Wilson, meteorology and physics were professionally indistinct. With his meteorological physics expertise, in WWI Millikan commanded perhaps the first meteorological observation and forecasting team essential to military operation in history.7 But even during peacetime meteorology is so much of a concern to everyone that a regular news segment is dedicated to it. Weather is the universal conversation topic, and life on land could not exist as we know it without clouds. One wonders then, why cloud formation is never covered in physics texts.

  19. Mixed mode fuel injector with individually moveable needle valve members

    2004-08-03

    A fuel injector includes a homogenous charge nozzle outlet set and a conventional nozzle outlet set controlled respectively, by first and second needle valve members. One of the needle valve members moves to an open position while the other needle valve member remains stationary for a homogeneous charge injection event. The former needle valve member stays stationary while the other needle valve member moves to an open position for a conventional injection event. One of the needle valve members is at least partially positioned in the other needle valve member. Thus, the injector can perform homogeneous charge injection events, conventional injection events, or even a mixed mode having both types of injection events in a single engine cycle.

    2016-12-01

    The aims of this study were to estimate the prevalence of smoking among SEPAR members, and their approach to smoking cessation in their patients. An online survey was completed by 640 members (496 pulmonologists, 45 nurses, 34 thoracic surgeons, 37 physiotherapists, and 28 other specialists). Of the members interviewed, 5% confessed that they were smokers: 3.5% pulmonologists; 8.9% nurses; 8.8% thoracic surgeons, and 13.5% physiotherapists. A total of 96% of members assign a lot or quite a lot of importance to setting an example; 98% of members always or often ask their patients about their smoking habit. The most effective anti-smoking intervention, according to 77% of members, is a combination of drugs and psychological support. These results are an indicator of the awareness and commitment of SEPAR members to smoking and its cessation.

  1. Lithofacies of Spencer Formation, western Tualatin Valley, Oregon

    Van Atta, R.O.

    1986-04-01

    The Spencer Formation crops out in a narrow band that trends north-northwest on the western edge of the Willamette and Tualatin Valleys, Oregon. It apparently conformably overlies mud rocks of either the Yamhill or the Nestucca Formation and is conformably overlain by the Pittsburgh Bluff Formation. The Spencer Formation consists of two members (informal): a lower highly micaceous sandstone (800-1000 ft) and an upper member that is micaceous siltstone and mudstone (1000-1300 ft). The lower member includes an upper part that is light-gray to creamy-gray, silty to muddy, pebbly lithic arkose to feldspathic litharenite, with minor arkose. Sorting is poor and beds may be laminated to ripple cross-laminated or massive and bioturbated with abundant mollusk shells, carbonized wood, and burrows. The lower part of the lower member is medium-gray to greenish-gray, silty, pumiceous lithic arkose to feldspathic litharenite. The texture tends to be more uniform and better sorted than that of the upper part of the member. Bedding is commonly massive due to bioturbation. The upper member is medium to dark-gray mudstone with thin pebble-conglomerate lenses. It intertongues with the lower member. Bioturbation, burrows, and carbonized wood are common. The trend in depositional environments appears to be from outer to mid-neritic (lower part, lower member) to shallow neritic, nearshore, and lagoonal (upper part, lower member, and upper member). The provenance of the Spencer Formation includes both proximal volcanics and distant plutonic and high-grade metamorphics.

  2. Contrasting diagenetic histories of concretions vs. host rocks, Lion Mountain Member, Riley formation (upper Cambrian), Texas

    McBride, E.F.

    1988-02-01

    White, elliptical, calcite-cemented concretion nuclei up to 1 m long contrast markedly in color, composition, and diagenetic history from more glauconite-rich concretion rinds and from dark-green glaucarenite host rocks. Concretion nuclei are loosely packed deposits of trilobite carapaces and minor quartz and glauconite that have intergranular volumes of 58%. The nuclei are shell-lag deposits that were cemented by calcite at the sea floor or after burial of a few meters. Concretion rinds, composed of subequal amounts of quartz and compactionally deformed glauconite, have an intergranular volume of only 32% and minor quartz overgrowths that preceded pore-occluding calcite cement. The rinds underwent burial for several million years to tens of millions of years to depths of several hundred meters before they were cemented. The host rock is predominately glauconite with very minor quartz and calcite cement. Strontium isotopic ratios of host-rock calcite cement are variable (0.7084 to 0.7093), but the lowest value suggests precipitation during the Middle Ordovician. In the absence of significant amounts of carbonate cement, the host rock underwent complete dissolution of trilobite carapaces and maximum compaction with total loss of porosity through squashing of glauconite grains. Maximum burial during this stage was completed by the end of Ordovician time.

    The Brereton Limestone is a shallow-water, open-marine carbonate deposited over peat or delta-plain muds after delta abandonment and a marine transgression. Data on autecology, lithology, insoluble residue content, and thickness were used to interpret the habitats of each biofacies. Biofacies V, a low-diversity biofacies dominated by brachiopods and ostracods, occupied turbid-water, mud- or shelly mud-bottom areas during influxes of detrital clays late in the abandonment of the Herrin delta and, also, early in the construction of the Jamestown delta. Low-relief carbonate mud mounds accumulated within and around baffles provided by thickets of phylloid algae and foraminifers, are capped locally by biofacies VI, a low-diversity biofacies dominated by ostracods. Biofacies VI, occupied the high subtidal to supratidal crests of algal mud mounds which had a stressed (possibly hypersaline) environment. Deeper water mud mounds were occupied by either Biofacies III, a crinoid-mixed fossil biofacies, or by Biofacies IV, which is dominated by fusulinids, strophomenids, and trilobites. Biofacies II, dominated by sponges, mollusks, and impunctate brachiopods, generally occurred on the flanks of the shallow-water mounds. Biofacies I, III, and IV also occurred in broad, muddy intermound areas and Biofacies III in narrow, winnowed intermound areas.

    Polymer-micelle complexes are currently under heavy investigation due to their potential applications in targeted drug delivery and gene therapy, yet the dynamics of the complex formation is still relatively unstudied. By varying the ratios of poly(styrene sulfonate) chains and cationic poly(dimethylaminoethyl methacrylate)-b-poly(styrene) micelles and the ionic strength of the system, we created a variety of complex configurations of different sizes and charges. The complexes were characterized dynamic light scattering and zeta potential measurements which provided information regarding the hydrodynamic radius, distribution of sizes, and effective charge.

  6. Searching for very late-type members of Hyades

    NASA Astrophysics Data System (ADS)

    Lee, Jinhee; Song, Inseok

    2016-01-01

    Hyades, a 750 Myr-old open cluster, has actively been examined due to its proximity (~50pc) and the large number of its members. The proximity enables us to identify very low-mass members of the cluster. For the member identification, the candidate star's kinematics, age, and metallicity should match to those of the bona fide members of the cluster. In this research, we searched for candidate members of Hyades cluster using a tool developed for calculating membership probability based on the Bayesian approach. Using two hypotheses, Hyades and field star, this algorithm computed probabilities for stars to be either Hyades members or field stars. In order to check the reliability of this algorithm, we tested it to 250 bona fide Hyades members; the algorithm successfully identified 99% of members at probability of > 95%. We first select kinematic candidates marginalizing over distances and radial velocities. We applied this algorithm to URAT1 catalogue stars in the range of 3h 20m < R.A. < 5h 20m and 0 deg < Dec. < +30 deg. Since most early-type members must have been discovered already, we focused on late-type members with m_{R} > 9.0. Because most of these late-type candidate members lack trigonometric distance measurements, using SED fitting and theoretical isochrone models, we computed SED distance for each star. Then, the membership probability was re-calculated including the SED distance. To select the final list of candidate members, stars with high membership probability and SED distance of < 100pc were kept. For reducing false positive, we excluded stars in old sequence using GALEX UV data. To confirm the true membership of the candidate members, we began to obtain high spectral resolution spectra to confirm their radial velocity and metallicity. Here, we present the sequence of candidate selection and its results.

  7. Planet Formation

    NASA Technical Reports Server (NTRS)

    Lissauer, Jack J.; Fonda, Mark (Technical Monitor)

    2002-01-01

    Modern theories of star and planet formation and of the orbital stability of planetary systems are described and used to discuss possible characteristics of undiscovered planetary systems. The most detailed models of planetary growth are based upon observations of planets and smaller bodies within our own Solar System and of young stars and their environments. Terrestrial planets are believed to grow via pairwise accretion until the spacing of planetary orbits becomes large enough that the configuration is stable for the age of the system. Giant planets begin their growth as do terrestrial planets, but they become massive enough that they are able to accumulate substantial amounts of gas before the protoplanetary disk dissipates. These models predict that rocky planets should form in orbit about most single stars. It is uncertain whether or not gas giant planet formation is common, because most protoplanetary disks may dissipate before solid planetary cores can grow large enough to gravitationally trap substantial quantities of gas. A potential hazard to planetary systems is radial decay of planetary orbits resulting from interactions with material within the disk. Planets more massive than Earth have the potential to decay the fastest, and may be able to sweep up smaller planets in their path. The implications of the giant planets found in recent radial velocity searches for the abundances of habitable planets are discussed, and the methods that are being used and planned for detecting and characterizing extrasolar planets are reviewed.

  12. Measurement and comparison of nursing faculty members' critical thinking skills.

    PubMed

    Blondy, Laurie C

    2011-03-01

    Nursing faculty members strive to teach students to think critically. It has long been assumed that nursing faculty members are good at critical thinking because they are expected to teach these skills to students, but this assumption has not been well supported empirically. Faculty members question their ability to think critically and are unsure of their skills. The purpose of this study was to address this assumption by measuring nursing faculty members' critical thinking skills and compare the faculty mean score to that of a student norming group, and to the mean scores of other nursing faculty studies. Findings can be used to increase nursing faculty members' understanding of their critical thinking skills, prompt discussion about critical thinking skills, and to help faculty members address concerns and uncertainty about the concept of critical thinking. This study also helps establish an empirical basis for future research.

    1994-01-01

    This study compared gang versus nongang high school students along measures of self-esteem, racial attitudes, and their self-professed role models. A total of 78 Caucasian (65 nongang and 13 gang members) and 77 African-American students (41 nongang and 36 gang members) participated. Results indicated that gang members had significantly lower levels of self-esteem compared to their nongang peers. All students, regardless of ethnicity, manifested negative racial stereotyping toward racial outgroups; gang members were not more racially prejudiced compared to other students. The role model data revealed that overall, gang members could name fewer role models than did their nongang peers. African-American students who were not gang members were much more likely to mention a parent or teacher as a role model. A regression analysis indicated that the absence of parental or teacher roles models was the best predictor of gang membership. These results are conceptualized within the framework provided by social identity theory.

    Objectives. To compare dominant learning styles of pharmacy students and faculty members and between faculty members in different tracks. Methods. Gregorc Style Delineator (GSD) and Zubin’s Pharmacists’ Inventory of Learning Styles (PILS) were administered to students and faculty members at an urban, Midwestern college of pharmacy. Results. Based on responses from 299 students (classes of 2008, 2009, and 2010) and 59 faculty members, GSD styles were concrete sequential (48%), abstract sequential (18%), abstract random (13%), concrete random (13%), and multimodal (8%). With PILS, dominant styles were assimilator (47%) and converger (30%). There were no significant differences between faculty members and student learning styles nor across pharmacy student class years (p>0.05). Learning styles differed between men and women across both instruments (p<0.01), and between faculty members in tenure and clinical tracks for the GSD styles (p=0.01). Conclusion. Learning styles differed among respondents based on gender and faculty track. PMID:23275657

    Many of steel thin wall closed section members are used by automobile industry. The local buckling of these elements that occur under compressive stress remains the main technological problem. To improve the performance of the members, the filling the inside of closed section with the low-density foaming material are usually used. In this study, we present the usefulness of axial compression and 3-point bending tests for the composite members filled with two kinds of epoxy resin. The difference between composite member and thin-walled member was investigated concerning their elastic and plastic collapse characteristics while tested with various deformation velocities. The adherent strength between thin-walled member and foaming material, and filling effect of the foaming material in the energy absorption characteristics was clarified.

    Researchers have shown inconsistencies in compliance, outcomes and attitudes of surgical team members related to surgical safety checklist briefings. The purpose of this study was to examine surgical circulator and scrub practitioners' perceptions of safety checklist briefings and team member involvement, and to identify potential improvements in the process based on those perceptions. An anonymous survey was conducted with members of the Association of periOperative Registered Nurses (AORN) and the Association of Surgical Technologists (AST). Questions focused on perceptions of checklist briefing efficacy and team member involvement in safety practices. From the 346 usable responses, a third respondent group of self-identified perioperative leaders emerged. Significant results were obtained related to leaders' perceptions, post-procedure briefings and various perceptions of team member involvement. Study results indicate that variances in safety practices continue as perceived by surgical team members thus presenting opportunities for further examination and improvement of processes in reducing surgical errors.

    2016-05-01

    Research has documented numerous benefits and challenges associated with receipt of hospice care in nursing homes; however, study of this partnership from the perspective of residents' family members has been limited. The purpose of this qualitative investigation was to explore family members' experience with hospice services received in the nursing home setting. Researchers conducted a secondary data analysis of 175 family member interviews using a thematic analytic approach. Findings highlighted the critical role of communication in supporting residents and their family members. Care coordination, support and oversight, and role confusion also impacted family members' experience of hospice care in the nursing home. Efforts directed at enhancing communication and more clearly articulating the roles of members of the health care team are indicated.

    The article covers data on prevalence of neurosensory deafness among civil aircraft crew members. The study revealed high level of neurosensory deafness in civil aircraft crew members, averaging to 50.8% in neurosensory deafness structure among noise-related occupations. Arterial hypertension appeared to be the most prevalent concurrent disease in civil aircraft crew members with neurosensory deafness, found in 47.5% of the patients examined - that considers arterial hypertension as a factor of neurosensory deafness progression.

    Habits, both good ones and bad ones, are pervasive in animal behavior. Important frameworks have been developed to understand habits through psychological and neurobiological studies. This work has given us a rich understanding of brain networks that promote habits, and has also helped us to understand what constitutes a habitual behavior as opposed to a behavior that is more flexible and prospective. Mounting evidence from studies using neural recording methods suggests that habit formation is not a simple process. We review this evidence and take the position that habits could be sculpted from multiple dissociable changes in neural activity. These changes occur across multiple brain regions and even within single brain regions. This strategy of classifying components of a habit based on different brain signals provides a potentially useful new way to conceive of disorders that involve overly fixed behaviors as arising from different potential dysfunctions within the brain's habit network.

    ABSTRACT The lipid phosphate phosphatase-related proteins (LPPRs), also known as plasticity-related genes (PRGs), are classified as a new brain-enriched subclass of the lipid phosphate phosphatase (LPP) superfamily. They induce membrane protrusions, neurite outgrowth or dendritic spine formation in cell lines and primary neurons. However, the exact roles of LPPRs and the mechanisms underlying their effects are not certain. Here, we present the results of a large-scale proteome analysis to determine LPPR1-interacting proteins using co-immunoprecipitation coupled to mass spectrometry. We identified putative LPPR1-binding proteins involved in various biological processes. Most interestingly, we identified the interaction of LPPR1 with its family member LPPR3, LPPR4 and LPPR5. Their interactions were characterized by co-immunoprecipitation and colocalization analysis using confocal and super-resolution microscopy. Moreover, co-expressing two LPPR members mutually elevated their protein levels, facilitated their plasma membrane localization and resulted in an increased induction of membrane protrusions as well as the phosphorylation of S6 ribosomal protein. Taken together, we revealed a new functional cooperation between LPPR family members and discovered for the first time that LPPRs likely exert their function through forming complex with its family members.

    The tumor suppressor p53 is induced by genotoxic stress in both normal and transformed cells and serves to transcriptionally coordinate cell cycle checkpoint control and programmed cell death responses. Macrophage migration inhibitory factor (MIF) is an autocrine and paracrine acting cytokine/growth factor that promotes lung adenocarcinoma cell motility, anchorage-independence and neo-angiogenic potential. Several recent studies indicate that the only known homolog of MIF, D-dopachrome tautomerase (D-DT - also referred to as MIF-2), has functionally redundant activities with MIF and cooperatively promotes MIF-dependent pro-tumorigenic phenotypes. We now report that MIF and D-DT synergistically inhibit steady state p53 phosphorylation, stabilization and transcriptional activity in human lung adenocarcinoma cell lines. The combined loss of MIF and D-DT by siRNA leads to dramatically reduced cell cycle progression, anchorage independence, focus formation and increased programmed cell death when compared to individual loss of MIF or D-DT. Importantly, p53 mutant and p53 null lung adenocarcinoma cell lines were only nominally rescued from the cell growth effects of MIF/D-DT combined deficiency suggesting only a minor role for p53 in these transformed cell growth phenotypes. Finally, increased p53 activation was found to be independent of aberrantly activated AMP-activated protein kinase (AMPK) that occurs in response to MIF/D-DT-deficiency but is dependent on reactive oxygen species (ROS) that mediate aberrant AMPK activation in these cells. Combined, these findings suggest that both p53 wildtype and mutant human lung adenocarcinoma tumors rely on MIF family members for maximal cell growth and survival.

  3. Discovery of a Satellite to Asteroid Family Member (702) Alauda

    Rojo and Margot [1] reported the discovery of a satellite to (702) Alauda from adaptive-optics imaging with the European Southern Observatory (ESO) 8-m Very Large Telescope (VLT) on Cerro Paranal, Chile. (702) Alauda (a = 3.2 AU, e = 0.02, i = 21 deg) has been identified as the largest member of a dynamical family [2,3], suggesting a possible origin of the satellite in the family formation event. The diameter of (702) Alauda is given in the IRAS Minor Planet Survey (IMPS) as 194.73 +/- 3.2 km [4]. If the primary and secondary have similar albedoes, the diameter of the satellite is about 5.5 km. This is based on the measured flux ratio between primary and secondary of 1250, possibly the largest ever observed for solar system binaries with adaptive optics. This is the first satellite discovered to a large minor planet of type B in the SMASSII taxonomy, which is defined by a linear featureless spectrum with bluish to neutral slope [5]. B-types are carbonaceous asteroids that are not well characterized. The mass and density estimates of B-type (2) Pallas vary by 50% [6,7]. Our ongoing determination of the satellite orbit will provide mass and density estimates for (702) Alauda. [1] Rojo and Margot, CBET 1016, 2007. [2] Foglia and Masi 2004, Minor Planet Bull. 41, 100.

    The Smackover Formation, a major hydrocarbon-producing horizon in the Mississippi Interior Salt Basin (MISB), conformably overlies the Norphlet Formation and is conformably overlain by the Buckner Anhydrite Member of the Haynesville Formation. The Norphlet-Smackover contact can be either gradational or abrupt. The thickness and lithofacies distribution of the Smackover Formation were controlled by the configuration of incipient paleotopography. The Smackover Formation has been subdivided into three informal members, referred to as the lower, middle and upper members.

    Enamel fluorosis is an irreversible structural enamel defect following exposure to supraoptimal levels of fluoride during amelogenesis. We hypothesized that fluorosis is associated with excess release of protons during formation of hypermineralized lines in the mineralizing enamel matrix. We tested this concept by analyzing fluorotic enamel defects in wild-type mice and mice deficient in anion exchanger-2a,b (Ae2a,b), a transmembrane protein in maturation ameloblasts that exchanges extracellular Cl− for bicarbonate. Defects were more pronounced in fluorotic Ae2a,b−/− mice than in fluorotic heterozygous or wild-type mice. Phenotypes included a hypermineralized surface, extensive subsurface hypomineralization, and multiple hypermineralized lines in deeper enamel. Mineral content decreased in all fluoride-exposed and Ae2a,b−/− mice and was strongly correlated with Cl−. Exposure of enamel surfaces underlying maturation-stage ameloblasts to pH indicator dyes suggested the presence of diffusion barriers in fluorotic enamel. These results support the concept that fluoride stimulates hypermineralization at the mineralization front. This causes increased release of protons, which ameloblasts respond to by secreting more bicarbonates at the expense of Cl− levels in enamel. The fluoride-induced hypermineralized lines may form barriers that impede diffusion of proteins and mineral ions into the subsurface layers, thereby delaying biomineralization and causing retention of enamel matrix proteins.

    The collective behaviors of community members for dynamic social networks are significant for understanding evolution features of communities. In this Letter, we empirically investigate the evolution properties of the new community members for dynamic networks. Firstly, we separate data sets into different slices, and analyze the statistical properties of new members as well as communities they joined in for these data sets. Then we introduce a parameter φ to describe community evolution between different slices and investigate the dynamic community properties of the new community members. The empirical analyses for the Facebook, APS, Enron and Wiki data sets indicate that both the number of new members and joint communities increase, the ratio declines rapidly and then becomes stable over time, and most of the new members will join in the small size communities that is s ≤ 10. Furthermore, the proportion of new members in existed communities decreases firstly and then becomes stable and relatively small for these data sets. Our work may be helpful for deeply understanding the evolution properties of community members for social networks.

  16. Vertical load capacities of roof truss cross members

    Gearhart, David F.; Morsy, Mohamed Khaled

    2016-01-01

    Trusses used for roof support in coal mines are constructed of two grouted bolts installed at opposing forty-five degree angles into the roof and a cross member that ties the angled bolts together. The load on the cross member is vertical, which is transverse to the longitudinal axis, and therefore the cross member is loaded in the weakest direction. Laboratory tests were conducted to determine the vertical load capacity and deflection of three different types of cross members. Single-point load tests, with the load applied in the center of the specimen and double-point load tests, with a span of 2.4 m, were conducted. For the single-point load configuration, the yield of the 25 mm solid bar cross member was nominally 98 kN of vertical load, achieved at 42 cm of deflection. For cable cross members, yield was not achieved even after 45 cm of deflection. Peak vertical loads were about 89 kN for 17 mm cables and 67 kN for the 15 mm cables. For the double-point load configurations, the 25 mm solid bar cross members yielded at 150 kN of vertical load and 25 cm of deflection. At 25 cm of deflection individual cable strands started breaking at 133 and 111 kN of vertical load for the 17 and 15 mm cable cross members respectively. PMID:27547484

    Board orientation provides a unique forum for an institution to help new board members understand the roles and responsibilities expected of them. It is a chance, too, to share essential information that the college or university thinks new trustees need to know. Moreover, it is an opportunity for the institution to bring new members up to date…

  19. Vertical load capacities of roof truss cross members.

    Gearhart, David F; Morsy, Mohamed Khaled

    Trusses used for roof support in coal mines are constructed of two grouted bolts installed at opposing forty-five degree angles into the roof and a cross member that ties the angled bolts together. The load on the cross member is vertical, which is transverse to the longitudinal axis, and therefore the cross member is loaded in the weakest direction. Laboratory tests were conducted to determine the vertical load capacity and deflection of three different types of cross members. Single-point load tests, with the load applied in the center of the specimen and double-point load tests, with a span of 2.4 m, were conducted. For the single-point load configuration, the yield of the 25 mm solid bar cross member was nominally 98 kN of vertical load, achieved at 42 cm of deflection. For cable cross members, yield was not achieved even after 45 cm of deflection. Peak vertical loads were about 89 kN for 17 mm cables and 67 kN for the 15 mm cables. For the double-point load configurations, the 25 mm solid bar cross members yielded at 150 kN of vertical load and 25 cm of deflection. At 25 cm of deflection individual cable strands started breaking at 133 and 111 kN of vertical load for the 17 and 15 mm cable cross members respectively.

    Investigated the problems team members perceive to exist on multidisciplinary teams. Results indicated the two major areas of concern for urban, multidisciplinary team members were: too constrictive a set of team roles and goals, and teams functioning under extensive pressure with minimal support.
