  3. Re-Os systematics of St. Paul's Rocks, equatorial Atlantic.

    NASA Astrophysics Data System (ADS)

    St. Paul's Rocks, small islets in the middle of the equatorial Atlantic (0°56'N, 29°22'W) just north of the St. Paul's Fracture zone, represent oceanic peridotites that are unique compared to abyssal peridotites. The main difference is the occurrence of modally metasomatized peridotites containing hornblende and pargasite. These mantle peridotites from St. Paul's Rocks show large Os isotopic heterogeneity, with present day 187Os/188Os ratios ranging from 0.1179 to 0.1273. In contrast, two hornblendite samples have very radiogenic Os isotopic compositions of 0.221 and 0.284. The Os concentrations vary from 0.003 ppb (hornblendite) to 5.8 ppb (spinel peridotite). Pargasite peridotites contain on average about 1.6 ppb Os. Even modally metasomatized samples with hornblende and pargasite have subchondritic Os isotopic ratios, indicating that enrichment processes did not disturb the Os isotopic system. The only indication of pervasive enrichment is a very high Re content in two of the amphibole peridotites (0.7 and 2.2 ppb). The unradiogenic Os isotopic ratios in the peridotites record ancient melting events with model ages of about 1.5 Ga. Three alkali basalts dredged on the flank of St. Paul's Rocks (1966 Atlantis II-20 cruise) have relatively high Os contents (62 to 167 ppt) and are quite radiogenic, with 187Os/188Os ranging from 0.167 to 0.239. Data from this study indicates that mixing of the different lithologies observed on St. Paul's Rocks cannot produce 187Os/188Os as high as that observed in the dredged basalts. On the other hand, the similar 187Os/188Os in the hornblendites and alkali basalts show that interaction between basalts and mantle peridotites took place. The very low Os isotopic ratios in St. Paul's Rocks, in conjunction with other Os studies from the equatorial Atlantic, indicate dispersed heterogeneities of old subcontinental lithospheric material in the oceanic mantle.

  9. Acoustic Coupling Effects in ST Paul's Cathedral, London

    NASA Astrophysics Data System (ADS)

    ANDERSON, J. S.; BRATOS-ANDERSON, M.

    2000-09-01

    In St Paul's Cathedral there are many arches, columns and cornices which enable the internal space to be divided into subspaces. The subspaces may be considered to be acoustically coupled via areas which connect the rooms. Two of the most acoustically important subspaces in the Cathedral are the choir and the space under the dome. The choir, the space within the wooden choir stalls, has more sound absorption than the rest of the building, which is mostly marble and Portland stone. In the model of coupled subspaces an acoustic energy balance equation, applied to a diffuse field, is derived for each subspace. In St Paul's Cathedral the internal space is divided into 70 acoustical subspaces. The initial-value problem which is formulated by the system of 70 acoustic energy balance equations with initial conditions has been reduced to the eigenvalue problem. The decay of sound energy density has been obtained for different locations in the Cathedral and for different positions of the sound source. Experimentally obtained sound decay curves are in good agreement with numerical results. Both the experimental and numerical results demonstrate the fine structure of reverberation.

  14. Preliminary results of a high-resolution seismic imaging investigation on St. Paul Island, Pribilof Islands, Alaska

    NASA Astrophysics Data System (ADS)

    2001-12-01

    St. Paul Island, one of the Alaskan Pribilof Islands, is located in the Bering Sea about 1100 km WSW of Anchorage, Alaska. Geologically, St. Paul's nearsurface lithology consists of basaltic lava flows and sills, with minor amounts of glacial sediments. To better understand the subsurface structure of St. Paul island, the U.S. Geological Survey acquired a series of high-resolution seismic imaging profiles across the island in June, 2000. The longest seismic profile is approximately 1.8-km-long and trends ENE. Shot and geophone spacing was 5 m, recorded with 162 channels. Seismic sources were generated using a Betsy Seisgun in { ~}0.3 m-deep holes. Approximately 2 s of data were recorded at a 0.5-ms sampling rate. Our study was designed to investigate the relationship between ground-water flow, basement rocks, and faults on St. Paul Island in an attempt to mitigate the effects of subsurface chemical contaminants. Seismic velocities range from about 500 m/s in the near surface to about 5000 m/s at varying depths, some of the high velocity layers appear as shallow as 40 m below the surface. The reflection data show a thin vaneer of sediments overlying layered basalts. Layered basalts vary in thickness from about 5 to 40 m near the surface, and these layers are faulted in places. The groundwater supply for St. Paul is derived from a shallow-depth water table that is, in places, a mixture of seawater and freshwater (Anderson, 1976). Vertical and lateral flow of ground-water is affected by the depth to basement rocks, which are believed to be largely impermeable and thus restrict the flow of ground-water. In addition, a series of observed faults that have vertically displaced basement rocks may act as barriers or as conduits to the flow of ground-water. In unconsolidated sediments, the ground-water table typically has velocities of { ~}1500 m/s. Using this velocity criteria, our data suggest that the ground-water table varies between 0 and 25 m depth along the profile

  15. Volcano hazards and potential risks on St. Paul Island, Pribilof Islands, Bering Sea, Alaska

    NASA Astrophysics Data System (ADS)

    Feeley, T. C.; Winer, G. S.

    2009-05-01

    Volcano hazards and potential risks on St. Paul Island, Alaska, are assessed on the basis of the recent volcanic history of the island. The long-term frequency of volcanic eruptions is estimated using a count of 40 identifiable vents considered to represent separate eruptions. Assuming regular temporal spacing of these events during the period 360,000 to 3230 y.b.p., the estimated mean recurrence time is 0.11 × 10 - 3 eruption/year and the eruptive interval is approximately 8900 years. Volcano hazards on St. Paul are associated exclusively with the eruption of low viscosity alkali basaltic magma. The most important are lava flows, tephra fallout, and base surges. Other hazards include volcanic gases, seismicity and ground deformation associated with dike intrusion beneath rift zones, and explosive lava-water interactions along coastal regions and water-saturated ground. The general characteristics of past volcanism on St. Paul indicate that the most likely styles of future eruptions will be (1) Hawaiian-style eruptions with fire fountains and pahoehoe lava flows issuing from one of two polygenetic shield volcanoes on the island; (2) Strombolian-style, scoria cone-building eruptions with associated tephra fallout and eruption of short pahoehoe lava flows; and (3) explosive Surtseyan-style, phreatomagmatic eruptions initiating at some point along St. Paul's insular shelf. Given the relatively restricted range in volcanic phenomena on St. Paul, the most significant question regarding volcano hazard and risk assessment is whether future eruptions will be confined to the same region on the island as the most recent activity. If future activity follows the recent past, resulting volcano hazards will most likely be located at inland areas sufficiently far from habitation that they will pose little threat to life or property. An important caveat, however, is that St. Paul is constructed almost entirely from the products of volcanic eruptions with vents located all over

    Relict woolly mammoth (Mammuthus primigenius) populations survived on several small Beringian islands for thousands of years after mainland populations went extinct. Here we present multiproxy paleoenvironmental records to investigate the timing, causes, and consequences of mammoth disappearance from St. Paul Island, Alaska. Five independent indicators of extinction show that mammoths survived on St. Paul until 5,600 ± 100 y ago. Vegetation composition remained stable during the extinction window, and there is no evidence of human presence on the island before 1787 CE, suggesting that these factors were not extinction drivers. Instead, the extinction coincided with declining freshwater resources and drier climates between 7,850 and 5,600 y ago, as inferred from sedimentary magnetic susceptibility, oxygen isotopes, and diatom and cladoceran assemblages in a sediment core from a freshwater lake on the island, and stable nitrogen isotopes from mammoth remains. Contrary to other extinction models for the St. Paul mammoth population, this evidence indicates that this mammoth population died out because of the synergistic effects of shrinking island area and freshwater scarcity caused by rising sea levels and regional climate change. Degradation of water quality by intensified mammoth activity around the lake likely exacerbated the situation. The St. Paul mammoth demise is now one of the best-dated prehistoric extinctions, highlighting freshwater limitation as an overlooked extinction driver and underscoring the vulnerability of small island populations to environmental change, even in the absence of human influence.

    School-based clinics in St. Paul have provided comprehensive health services, including reproductive health care, for almost two decades. This study examines the effects of those clinics on the birthrates in their respective schools, using a newly developed methodology with numerous advantages over previous methods for estimating student birthrates. Confidentially matching the names of female students from school records with the names of mothers on birth records at the Department of Health provided birthrates for each of the St. Paul public high schools with clinics for each year between 1971 and 1986. The results show that birthrates fluctuated dramatically from one year to the next, but school-wide birthrates were not significantly lower in the years immediately following the opening of a clinic than in the years preceding it.

    The structure of the acoustic basement of the eastern part of the St. Paul multifault transform fracture system hosts rift paleovalleys and a paleonodal depression that mismatch the position of the currently active zones. This displacement zone, which is composed of five fault troughs, is unstable in terms of the position of the rift segments, which jumped according to redistribution of stresses. The St. Paul system is characterized by straightening of the transform transition between two remote segments of the Mid-Atlantic Ridge (MAR). The eastern part of the system contains anomalous bright-spot-like reflectors on the flattened basement, which is a result of atypical magmatism, that forms the standard ridge relief of the acoustic basement. Deformations of the acoustic basement have a presedimentation character. The present-day deformations with lower amplitude in comparison to the basement are accompanied by acoustic brightening of the sedimentary sequence. The axial Bouguer anomalies in the east of the system continue to the north for 120 km from the active segments of the St. Paul system. Currently seismically active segments of the spreading system are characterized by increasing amplitudes of the E-W displacement along the fault troughs. Cross-correlation of the lengths of the active structural elements of the MAR zone (segments of the ridge and transform fracture zones of displacement) indicates that, statistically, the multifault transform fracture system is a specific type of oceanic strike-slip faults.

  11. A retrospective diagnosis of epilepsy in three historical figures: St Paul, Joan of Arc and Socrates.

    PubMed

    Muhammed, Louwai

    2013-11-01

    It has been suggested that undiagnosed epilepsy profoundly influenced the lives of several key figures in history. Historical sources recounting strange voices and visions may in fact have been describing manifestations of epileptic seizures rather than more supernatural phenomena. Well-documented accounts of such experiences exist for three individuals in particular: Socrates, St Paul and Joan of Arc. The great philosopher Socrates described a 'daimonion' that would visit him throughout his life. This daimonion may have represented recurrent simple partial seizures, while the peculiar periods of motionlessness for which Socrates was well known may have been the result of co-existing complex partial seizures. St Paul's religious conversion on the Road to Damascus may have followed a temporal lobe seizure which would account for the lights, voices, blindness and even the religious ecstasy he described. Finally, Joan of Arc gave a detailed narrative on the voices she heard from childhood during her Trial of Condemnation. Her auditory hallucinations appear to follow sudden acoustic stimuli in a way reminiscent of idiopathic partial epilepsy with auditory features. By analysing passages from historical texts, it is possible to argue that Socrates, St Paul and Joan of Arc each had epilepsy. PMID:24585826

  13. Asthenospheric percolation of alkaline melts beneath the St. Paul region (Central Atlantic Ocean)

    NASA Astrophysics Data System (ADS)

    Brunelli, Daniele; Seyler, Monique

    2010-01-01

    Two peridotite suites collected by submersible in the equatorial Atlantic Ocean (Hekinian et al., 2000) were studied for textures, modes, and in situ major and trace element compositions in pyroxenes. Dive SP12 runs along the immersed flank of the St. Peter and Paul Rocks islets where amphibole-bearing, ultramafic mylonites enriched in alkalies and incompatible elements are exposed (Roden et al., 1984), whereas dive SP03 sampled a small intra-transform spreading centre situated about 370 km east of the St. Peter and Paul Rocks. Both suites are characterized by undeformed, coarse-grained granular textures typical of abyssal peridotites, derived from residual mantle after ˜ 15% melting of a DMM source, starting in the garnet stability field. Trace element modelling, textures and lack of mineral zoning indicate that the residual peridotites were percolated, reacted and refertilized by ˜ 2.6% partially aggregated melts in the uppermost level of the melting region. This relatively large amount of refertilization is in agreement with the cold and thick lithosphere inferred by previous studies. Freezing of trapped melts occurred as the peridotite entered the conductive layer, resulting in late-stage crystallization of olivine, clinopyroxene, spinel, ± plagioclase. Chondrite-normalized REE patterns in clinopyroxenes from SP03 indicate that they last equilibrated with (ultra-) depleted partial melts. In contrast, REE concentrations in clinopyroxenes from SP12 display U and S shaped LREE-enriched patterns and the calculated compositions of the impregnating melts span the compositional range of the regional basalts, which vary from normal MORB to alkali basalt sometimes modified by chromatographic fractionation with no, or very limited, mineral reaction. Thus the mylonitic band forming the St. Peter and St. Paul Rocks ridge is not a fragment of subcontinental lithospheric mantle left behind during the opening of the Central Atlantic, nor the source of the alkaline basalts

    St. Paul Island, AK, part of the Pribilofs, is an island remnant of the Bering Land Bridge, a possible coastal Picea refugium at the last glacial maximum, and a Holocene refugium for Mammuthus primigenius. A prior pollen record from Lake Hill indicates that St. Paul was predominantly herb tundra during the last glacial maximum followed by a shrub tundra in the early Holocene (Colinvaux, 1980). Subsequently, three radiocarbon dates on bones from Qagnax Cave indicate a last appearance of Mammuthus primigenius of 6.5 ka on St. Paul (Veltre et al. 2008). In March 2013, our team retrieved a 13.5 m composite core from Lake Hill to refine the extinction timing chronology, assess environmental change during the extinction interval, and test hypotheses about vegetation-megafauna feedback. This paper reports the results from modern botanical survey and analyses of fossil pollen, Sporormiella and other coprophilous spores, anchored by a new radiocarbon chronology consisting of seven AMS dates. Presently, bryophytes, Equisetum, Poaceae, Juncaceae, Salix and Viola commonly occur at the lake margin, accompanied increasingly by sedge meadow taxa with greater distance from the water's edge, especially Cyperaceae, Asteraceae, Apiaceae, Lupinus, Rubus and Valeriana. Sporormiella is consistently present in low abundances (2%, ~700 grains/cm3) in the late glacial and early Holocene until a drop to zero at 6,050 yr BP, remaining absent during the middle and late Holocene when it reappears at 1904 AD. The timing of Sporormiella decline and reappearance match well to the youngest mammoth bone date and the historic reintroduction of reindeer (1911 AD) on St. Paul Island. After 11 ka, major pollen types include Apiaceae, Poaceae, Cyperaceae, Artemisia and Salix, with lower abundances of Betula, Alnus and Ericaceae, consistent with herb tundra with some shrubs. Degraded Picea pollen grains are found at 12,240 yr BP in very low concentrations (223 grains/cm3), indicating long

    The purpose of this analysis is to estimate how much electricity the redeveloped Ford Motor Company assembly plant site in St. Paul, Minnesota, might consume under different development scenarios and how much rooftop photovoltaic (PV) generation might be possible at the site. Because the current development scenarios are high-level, preliminary sketches that describe mixes of residential, retail, commercial, and industrial spaces, electricity consumption and available rooftop area for PV under each scenario can only be grossly estimated. These results are only indicative and should be used for estimating purposes only and to help inform development goals and requirements moving forward.

    Sponges are one of the most complex symbiotic communities and while the taxonomic composition of associated microbes has been determined, the biggest challenge now is to uncover their functional role in symbiosis. We investigated the microbiota of two widely distributed sponge species, regarding both their taxonomic composition and their functional roles. Samples of Didiscus oxeata and Scopalina ruetzleri were collected in the oceanic archipelago of St Peter and St Paul and analysed through metagenomics. Sequences generated by 454 pyrosequencing and Ion Torrent were taxonomically and functionally annotated on the MG-RAST server using the GenBank and SEED databases, respectively. Both communities exhibit equivalence in core functions, interestingly played by the most abundant taxa in each community. Conversely, the microbial communities differ in composition, taxonomic diversity and potential metabolic strategies. Functional annotation indirectly suggests differences in preferential pathways of carbon, nitrogen and sulphur metabolisms, which may indicate different metabolic strategies. PMID:25873456

    A hydrologic reconnaissance of the southeastern part of St. Paul Island, Pribilof Islands, Alaska, was made in August 1979 to determine if sufficient freshwater is available for a proposed harbor and fish-processing facility. Only three wells were being used in 1979, two by the community of St. Paul and one by the Coast Guard Loran facility. All wells are in the southeastern part of the island. The island has no established surface drainage, and no springs were found on the eastern part of the island during the survey. Drainage of ground-water from the island is assumed to be by seepage through the sandy deposits along the east coast and possibly by undersea discharge elsewhere on the island. On the basis of present well yields, amount of freshwater inferred to be present below the water table, and potential recharge from precipitation, it is concluded that it should be possible to design a well field in the southeastern part of the island that could yield more than a million gallons per day without danger of inducing saline water into the well field. The water is of good chemical quality. (USGS)

    1997-01-01

    Following an oil spill off St Paul Island, Alaska in February 1996, persistence rates and detection probabilities of oiled king eider (Somateria spectabilis) carcasses were estimated using the Cormack-Jolly-Seber model. Carcass persistence rates varied by day, beach type and sex, while detection probabilities varied by day and beach type. Scavenging, wave action and weather influenced carcass persistence. The patterns of persistence differed on rock and sand beaches and female carcasses had a different persistence function than males. Weather, primarily snow storms, and degree of carcass scavenging, diminished carcass detectability. Detection probabilities on rock beaches were lower and more variable than on sand beaches. The combination of persistence rates and detection probabilities can be used to improve techniques of estimating total mortality.

    Mesophotic reef fish assemblages (30-90 m depth) of the small and remote St. Peter and St. Paul's Archipelago (SPSPA), Mid-Atlantic Ridge, Brazil, were characterized using remotely operated vehicles. Ordination analyses identified distinct fish assemblages in the upper (30-50 m) and lower (50-90 m) mesophotic zones, the former characterized by high abundances of species that are also abundant at euphotic reefs ( Caranx lugubris, Melichthys niger, Stegastes sanctipauli and Chromis multilineata) and the latter dominated by two mesophotic specialists ( Prognathodes obliquus and Chromis enchrysura). Planktivores dominated fish assemblages, particularly in the upper mesophotic zone, possibly due to a greater availability of zooplankton coming from the colder Equatorial Undercurrent in mesophotic depths of the SPSPA. Turf algae, fleshy macroalgae and scleractinian corals dominated benthic assemblages between 30 and 40 m depth, while bryozoans, black corals and sponges dominated between 40 and 90 m depth. Canonical correspondence analysis explained 74 % of the relationship between environmental characteristics (depth, benthic cover and complexity) and structure of fish assemblages, with depth as the most important independent variable. Juveniles of Bodianus insularis and adults of P. obliquus and C. enchrysura were clearly associated with branching black corals ( Tanacetipathes spp.), suggesting that black corals play key ecological roles in lower mesophotic reefs of the SPSPA. Results from this study add to the global database about mesophotic reef ecosystems (MREs) and provide a baseline for future evaluations of possible anthropogenic and natural disturbances on MREs of the SPSPA.

  5. Basaltic volcanism in the Bering Sea: geochronology and volcanic evolution of St. Paul Island, Pribilof Islands, Alaska

    2004-07-01

    The evolution of a Pleistocene to Holocene basaltic volcanic field in the back-arc region of the Aleutian subduction system is investigated at St. Paul Island, Alaska, one of the youngest eruptive centers in the Bering Sea basalt province. New 40Ar/ 39Ar and 14C age determinations indicate that subaerial volcanic activity forming the island began as early as 540 ka and has continued nearly to the present; the youngest eruption occurred approximately 3230 years BP. Magmas erupted on St. Paul are basaltic with MgO contents ranging from 14 to 4 wt.% and phenocryst assemblages of olivine+clinopyroxene±plagioclase; all are alkalic. The surface of St. Paul is composed mainly of numerous tephra cones surrounded by coalescing, low-viscosity pahoehoe lava flows. A central highland spans the island from east to west and is constructed of relatively young eruptive centers where rocks show a minimum of weathering and little deformation by faulting. In contrast, older lava flows forming the wave-eroded base of the island are gently to moderately tilted and faulted. Geochronologic, stratigraphic, and geochemical data indicate that eruptive styles on St. Paul evolved from early, mostly effusive eruptions of chemically little evolved lavas that form the base of the island, to more explosive monogenetic scoria cones, to polygenetic centers forming shields by repeated effusive eruptions of evolved low-viscosity lavas. Localization of the monogenetic and polygenetic centers appears to be related to east-west and northeast-southwest trending fault and fissure systems, with polygenetic centers located at intersections of major structures. The combined volcanic and compositional changes on St. Paul Island suggest that the magmatic system as a whole may be trending toward eruption of more evolved magmas related to the progressive development of crustal magma chambers in which crystal fractionation and magmatic differentiation are occurring.

    Isolated oceanic islands constitute interesting model systems for the study of colonization processes, as several climatic and oceanographic phenomena have played an important role in the history of the marine ichthyofauna. The present study describes the presence of two morphotypes of Caranx lugubris, in the St. Peter and St. Paul Archipelago located in the mid-Atlantic. Morphotypes were compared in regard to their morphological and cytogenetic patterns, using C-banding, Ag-NORs, staining with CMA3/DAPI fluorochromes and chromosome mapping by dual-color FISH analysis with 5S rDNA and 18S rDNA probes. We found differences in chromosome patterns and marked divergence in body patterns which suggest that different populations of the Atlantic or other provinces can be found in the Archipelago of St. Peter and St. Paul.

    The Amsterdam-St. Paul (ASP) plateau is located in the central part of the Indian Ocean and results from the interaction between the ASP hot spot and the Southeast Indian Ridge (SEIR). It is located near the diffuse boundary between the Capricorn and Australian plates. The seamount chain of the Dead Poets (CDP) is northeast of the ASP plateau and may represent older volcanism related to the ASP hot spot; this chain consists of two groups of seamounts: (1) large flat-topped seamounts formed 8-10 Ma and (2) smaller conical seamounts formed during the last 2 Myr. The ASP hot spot has produced two pulses of magmatism that have been ponded under the ASP plateau and erupted along the divergent boundary between the Capricorn and Australian plates. The N65° orientation of the CDP as well as the seamount's elongated shapes support an opening motion between the Capricorn and Australian plates along a suture oriented in the N155° direction. This motion compared to the Antarctic plate amounts to an apparent velocity of 7.7 cm/yr northeastward for the Capricorn-Australian block. This motion does not fit with a fixed plume model. We suggest, therefore, that the ASP plume experienced a motion of about 1-2 cm/yr to the SW, which is opposite to the asthenospheric flow in this region and suggests a deep-seated plume.

    In 2010, Coxiella burnetii was identified at a high prevalence in the placentas of Northern fur seals (Callorhinus ursinus) collected at a single rookery on St. Paul Island Alaska; an area of the United States where the agent was not known to be present. As contamination was hypothesized as a potential cause of false positives, but nothing was known about environmental C. burnetii in the region, an environmental survey was conducted to look for the prevalence and distribution of the organism on the island. While environmental prevalence was low, two strains of the organism were identified using PCR targeting the COM1 and IS1111 genes. The two strains are consistent with the organism that has been increasingly identified in marine mammals as well as a strain type more commonly found in terrestrial environments and associated with disease in humans and terrestrial animals. Further work is needed to elucidate information regarding the ecology of this organism in this region, particularly in association with the coastal environment. PMID:22747976

    1983-01-01

    Minneapolis-St. Paul is recognized as a prime example of health care competition. Policymakers and others have been asked to look to the Twin Cities as a model upon which to base new competitive initiatives in the health care sector. Yet little is known about the impact of Health Maintenance Organizations (HMOs) on other health care providers. This study examines the effects of the area's seven health maintenance organizations on the local hospital community. Three questions are addressed. First, is the situation in the Twin Cities unique? A comparison of case study findings and the available literature together with hospital data from similarly HMO-penetrated markets suggests that the Twin Cities' hospital market is indeed different. Second, what is the nature of hospital-HMO interaction? The flexibility of contracting apparently allows hospitals to affiliate successfully with an HMO under a variety of service and reimbursement agreements. Third, what effect has HMO activity had on community-wide utilization? While HMO enrollees clearly use fewer hospital days and the trend in the community is toward fewer days, attributing the change to HMOs is difficult. A large portion of the differences between HMO and community-wide utilization levels is attributable to differences in population. PMID:10309856

    The Amsterdam-St Paul (ASP) oceanic plateau results from the interaction between the ASP hot spot and the Southeast Indian ridge. A volcanic chain, named the Chain of the Dead Poets (CDP), lies to its northward tip and is related to the hot spot intraplate activity. The ASP plateau and CDP study reveals that ASP plume composition is inherited from oceanic crust and pelagic sediments recycled in the mantle through a 1.5 Ga subduction process. The ASP plateau lavas have a composition (major and trace elements and Sr-Nd-Pb-Hf isotopes) reflecting the interaction between ASP plume and the Indian MORB mantle, including some clear DUPAL input. The Indian upper mantle below ASP plateau is heterogeneous and made of a depleted mantle with lower continental crust (LCC) fragments probably delaminated during the Gondwana break-up. The lower continental crust is one of the possible reservoirs for the DUPAL anomaly origin that our data support. The range of magnitude of each end-member required in ASP plateau samples is (1) 45% to 75% of ASP plume and (2) 25% to 55% of Indian DM within 0% to a maximum of 6% of LCC layers included within. The three end-members involved (plume, upper mantle and lower continental crust) and their mixing in different proportions enhances the geochemical variability in the plateau lavas. Consequently, the apparent composition homogeneity of Amsterdam Island, an aerial summit of the plateau, may result from the presence of intermediate magmatic chambers into the plateau structure.

    The conversion of Saul to Paul was a major event in the history of Western culture. Compared with its impact, any medical comments may seem redundant, but they have kept their place in the literature for many centuries. The flashing light that caused Saul to fall is often explained as solar retinopathy or keratitis, a seizure, or even a hysterical fit. These interpretations propose either a trivial injury or disease that would interfere with mental health. Neither version is quite compatible with the dramatic dimension of the event and with Paul's later achievements and sufferings. In later years, Paul became a great manager, preacher and writer who was able to carry on under any kind of duress, though not without very painful reactions. He was suffering from bouts of unilateral headache, and also from a chronic eye condition which gave great trouble to his followers but did not cause lasting damage; the descriptions fulfil the criteria for migraine without aura of the 1988 Headache Classification. If the flashing light that caused Paul to fall down is interpreted as a visual migraine aura, with the additional symptoms of "not seeing" or photophobia and anorexia, it falls into place with his later history of migraine.

    We used wooden blocks to estimate the proportion of oiled seabird carcasses that were likely to be recovered on beaches of St Paul Island, Alaska following a near-shore oil spill. We released a total of 302 blocks 6 km north of the island in 1997 at the site of a 17 II 1996 oil spill. We used a paired design and released half the blocks when the winds were onshore and released the second half when the winds were offshore. We systematically searched beaches after the second release to recover blocks. We recovered 93 of 152 (61%) blocks released when winds were onshore but only 1 of 150 (0.7%) blocks released when winds were offshore. Given that winds following the 1996 spill were offshore, we conclude that most birds killed at sea following the 1996 spill were likely not recovered on beaches.

  16. Evidence for fractionation of Quaternary basalts on St. Paul Island, Alaska, with implications for the development of shallow magma chambers beneath Bering Sea volcanoes

    Feeley, T. C.; Winer, G. S.

    1999-04-01

    St. Paul Island is the youngest volcanic center in the Bearing Sea basalt province. We have undertaken a field, petrographic, and geochemical study of select St. Paul volcanic rocks in order to better understand their differentiation; specifically, to test the hypothesis that magmas erupted from individual Bering Sea basaltic volcanoes are not related by shallow-level processes such as crystal fractionation. Petrographically, all of the St. Paul volcanic rocks are olivine-, plagioclase-, and clinopyroxene-phyric. Textural features and modal contents of olivine phenocrysts, however, vary widely throughout the spectrum of basalt compositions. Although differing in size and abundance, olivine phenocrysts in all rock compositions are euhedral and commonly skeletal, suggesting rapid growth during ascent or eruptive quenching. None, however, display reaction textures with surrounding groundmass liquid. Compositionally, the St. Paul volcanic rocks are basalts and tephritic basalts and all have high contents of normative nepheline (8% to 16%). Concentrations of many major and incompatible trace elements display no clear correlations with bulk-rock SiO 2 and MgO contents or modal abundances of phenocrysts, suggesting that much of the compositional diversity of these magmas reflects variable mantle sources and degrees of partial melting. Similarly, chondrite-normalized REE patterns show variable degrees of light REE enrichment (La n=70-90) that do not correlate with bulk-rock mg-numbers. In contrast, concentrations of compatible trace elements (Ni, Cr, and Co) are positively correlated with MgO contents and modal percentages of olivine phenocrysts. Maximum forsterite contents of olivine phenocryst cores in most St. Paul rocks decrease with decreasing bulk-rock mg-number and are similar to the calculated equilibrium range. This is evidence that the high mg-numbers are magmatic and do not result from olivine accumulation. Instead, major and compatible trace element mass

    A great blue heron (Ardea herodias) colony on Pig's Eye Island on the Mississippi River near St. Paul, Minnesota, USA, is located near several potential perfluorinated compound (PFC) sources. The PFC concentrations in great blue heron eggs reported from a 1993 collection from the Pig's Eye colony were among the highest measured in bird eggs worldwide. The objective of this investigation was to determine whether PFC concentrations in great blue heron eggs at the Pig's Eye colony have changed since 1993. Total PFC concentrations in great blue heron eggs collected at the Pig's Eye colony in 2010 and 2011 (geometric mean=340 and 492 ng/g wet wt) were 60% lower than the 1993 collection (1,015 ng/g wet wt). Among PFCs, perfluoroalkyl sulfonate concentrations were lower and perfluoroalkyl carboxylate concentrations were higher in the 2010 and 2011 collections. Two of 20 (10%) of the eggs analyzed from Pig's Eye in 2010 and 2011 were >1,000 ng PFCs/g wet weight and the maximum PFC value (2,506 ng PFCs/g wet wt) measured in 2010 and 2011 was among the highest PFC concentration reported in bird eggs. These high concentrations are at levels associated with physiological and neurological effects in birds. PMID:23378367

    Ground-water baseflow to six subreaches of the Upper Mississippi River were estimated for July 1988, a period of drought. Ground-water baseflow to each subreach was estimated on the basis of streamflow gains determined from records of daily discharge at gaging stations. Streamflow gains were adjusted for estimated inflow from tributaries, municipal and industrial discharges, withdrawals, and evaporation. Low-flow frequency characteristics were computed for the Mississippi River near Anoka, Minnesota and the Mississippi River at St. Paul, Minnesota.

    The aim of this study was to investigate the planktonic and the holobiont Madracis decactis (Scleractinia) microbial diversity along a turbulence-driven upwelling event, in the world's most isolated tropical island, St Peter and St Paul Archipelago (SPSPA, Brazil). Twenty one metagenomes were obtained for seawater (N = 12), healthy and bleached holobionts (N = 9) before, during and after the episode of high seawater turbulence and upwelling. Microbial assemblages differed between low turbulence-low nutrient (LLR) and high-turbulence-high nutrient (HHR) regimes in seawater. During LLR there was a balance between autotrophy and heterotrophy in the bacterioplankton and the ratio cyanobacteria:heterotrophs ~1 (C:H). Prochlorales, unclassified Alphaproteobacteria and Euryarchaeota were the dominant bacteria and archaea, respectively. Basic metabolisms and cyanobacterial phages characterized the LLR. During HHR C:H < < 0.05 and Gammaproteobacteria approximated 50% of the most abundant organisms in seawater. Alteromonadales, Oceanospirillales, and Thaumarchaeota were the dominant bacteria and archaea. Prevailing metabolisms were related to membrane transport, virulence, disease, and defense. Phages targeting heterotrophs and virulence factor genes characterized HHR. Shifts were also observed in coral microbiomes, according to both annotation-indepent and -dependent methods. HHR bleached corals metagenomes were the most dissimilar and could be distinguished by their di- and tetranucleotides frequencies, Iron Acquision metabolism and virulence genes, such as V. cholerae-related virulence factors. The healthy coral holobiont was shown to be less sensitive to transient seawater-related perturbations than the diseased animals. A conceptual model for the turbulence-induced shifts is put forward.

During HHR C:H < < 0.05 and Gammaproteobacteria approximated 50% of the most abundant organisms in seawater. Alteromonadales, Oceanospirillales, and Thaumarchaeota were the dominant bacteria and archaea. Prevailing metabolisms were related to membrane transport, virulence, disease, and defense. Phages targeting heterotrophs and virulence factor genes characterized HHR. Shifts were also observed in coral microbiomes, according to both annotation–indepent and -dependent methods. HHR bleached corals metagenomes were the most dissimilar and could be distinguished by their di- and tetranucleotides frequencies, Iron Acquision metabolism and virulence genes, such as V. cholerae-related virulence factors. The healthy coral holobiont was shown to be less sensitive to transient seawater-related perturbations than the diseased animals. A conceptual model for the turbulence-induced shifts is put forward.

    To document and quantify subsistence harvests of fish and wildlife resources, and provide topics for subsequent key respondent interviews to collect local and traditional knowledge (LTK) about the Bering Sea ecosystem, comprehensive household harvest surveys were conducted in four Bering Sea Alaska Native communities: Akutan, Emmonak, Savoonga, and Togiak. In a fifth community, St. Paul, annual programs to document two key subsistence resources, fur seals and sea lions, continued. Surveys documented relatively high and diverse subsistence harvests, consistent with earlier research that demonstrated the continuing economic, social, and cultural importance of subsistence uses of wild resources. The research also found differences in subsistence use patterns compared to previous years' studies, such as harvest levels, harvest composition, and diversity of resources used, although differences between study years were not uniform across communities. Survey respondents, as well as key respondents in subsequent interviews, identified a complex range of personal, economic, and environmental factors when comparing subsistence uses in the study year with other years, such as increasing costs of fuel and purchased food, commercial fisheries harvests and bycatch, more persistent storms and less predictable winds, and reduced sea ice. Such conditions affect resource abundance and locations as well as access to fish and wildlife populations, and may shape long-term trends. So far, as in the past, families and communities have adapted to changing economic, social, and environmental conditions, but the future is less clear if such changes intensify or accelerate. Local community residents should be essential partners in future efforts to understand these complex processes that affect the natural resources of the Bering Sea.

    The COLMEIA cruise, held in the Equatorial Atlantic, in the area of the St. Paul transform system, is part of a joint effort between France and Brazil for the study of the Mid-Atlantic ridge near the St. Peter & St. Paul's Rocks. The scientific objective of the cruise was to study in detail the temporal evolution of the complex transform plate boundary, and the origin of the St. Peter-St. Paul mylonitic massif. This area of the Mid-Atlantic ridge was considered to be a mantle 'cold spot', thus a magma-starved region with large occurrences of mantle-derived units outcropping at the seafloor. During the cruise we acquired multibeam echosounder bathymetry, backscattering, water column acoustic data, gravity, magnetics and seismics. 31 dredges successfully returned a wide variety of rocks, including basalts, gabbros and peridotites. The 15 CTD stations with nephelometric profiles casted in the transform region returned a single hydrothermal plume signal, probably sourced in the MAR segment south of the St. Paul system, while no hydrothermal activity was directly detected inside the transform system. 5 autonomous hydrophones were moored in the SOFAR channel around the study area in order to monitor the seismic activity and whale presence; they will be recovered mid-2014. Both bathymetry data and recovered rocks show that the image of a regional amagmatic MAR cannot be applied to the whole of the St. Paul system. The ridge segments are short and narrow, with deep axial valleys. Axial depths are below 4000 m on average, and reach 5400 m in some nodal basins. There is no evidence for a clearly defined neo-volcanic ridge on the axial valley floors, but a few volcanoes were observed in the axial valley of the central segment. The pattern of off-axis abyssal hills is highly variable from one segment to another. The northern segment displays a long sequence of magmatic abyssal hills. The central segment shows both hummocky ridges probably of magmatic origin, alternated to

  6. The Ninetyeast Ridge and its Relation to the Kerguelen, Amsterdam and St. Paul Mantle Plumes in the Indian Ocean

    The Ninetyeast Ridge, a 5000 km long north-south oriented submarine volcanic ridge in the eastern Indian Ocean, has been interpreted to have formed from magmatism associated with the deep-seated Kerguelen mantle plume as the Indian plate drifted rapidly northward during the Late Cretaceous. Samples recovered along the ridge have the characteristic Dupal geochemical signatures of Indian Ocean basalts, but debate concerning the nature and number of components in the mantle source contributing to the formation of these basalts persists. New MC-ICP-MS (Pb, Hf) and TIMS (Sr, Nd) isotopic analyses were determined for tholeiites representative of the ~180 m of basaltic basement recovered from three drill sites (758: 82 Ma; 757: 58 Ma, 756: 43 Ma) along the Ninetyeast Ridge during ODP Leg 121. These analyses provide substantially greater precision compared to earlier studies (ppm vs. % range) after removal of the effects of post-magmatic alteration by thorough acid leaching [1]. No systematic temporal or spatial isotopic variations are observed along the ridge, which is inconsistent with the hypothesis of an aging mantle plume origin for the ridge [2]. The Pb-Hf-Sr-Nd isotopic compositions of the Ninetyeast Ridge basalts are generally intermediate between those of the volcanic products of the Kerguelen and Amsterdam-St. Paul mantle plumes and define mixing trends between components with relatively enriched and depleted signatures. At least three, possibly four, source components are required to explain the observed isotopic variability along the Ninetyeast Ridge. The less radiogenic isotopic signatures of some Ninetyeast Ridge basalts (87Sr/86Sr = 0.70381-0.70438) are not consistent with mixing with shallow level Indian MORB and are instead consistent with the presence of a relatively depleted component in a deep mantle source. A similar source component is also identified in other Indian ocean island basalts (e.g., Crozet, Réunion [3, 4]) with typical EM-1-like

    Studies of northern fur seal (Callorhinus ursinus Linnaeus, 1758) infection by the filariid nematode Acanthocheilonema odendhali were carried out in 2011-2012 on St. Paul Island, Pribilof Archipelago, Alaska. Skins of 502 humanely harvested northern fur seals from haul-out areas of five rookeries, Polovina (n = 122), Morjovi (n = 54), Zapadni (n = 72), Lukanin (n = 109), and Gorbatch (n = 145), were examined. A. odendhali was found in 18% of northern fur seals. The prevalence of infection ranged from 12.5% up to 22.9% on different haul-out areas on the island. The mean intensity of infection was 1.3 (range 1-7). Detailed morphological examination of collected specimens was performed using light microscopy. Several characters were added to the morphological description of the species, among them lateral thickening of the body cuticle, especially prominent in males, variations in number and position of genital papillae in males, transverse striation of the cuticle, and terminal dilation on tail end in microfilariae. The adult specimens studied had a shorter esophagus than type specimens from the California sea lion described by Perry (1967). Comparison of partial sequences of the mitochondrial cox1 gene from specimens collected from five sampling sites on St. Paul Island and a specimen from the type host and territory in California showed no significant differences and strongly supported conspecificity of the material from Alaska with A. odendhali.

  10. Characterization of ground-water discharge from bedrock aquifers to the Mississippi and Minnesota Rivers at three areas, Minneapolis-St. Paul area, Minnesota

    1994-01-01

    The hydrogeology at three areas along the Mississippi and Minnesota Rivers in the Minneapolis-St. Paul area were studied to characterize ground-water discharge from bedrock aquifers to the two rivers. Along the Mississippi River between Fridley and Brooklyn Center, a buried valley underlying the Mississippi River cuts through the overlying terrace deposits and glacial-drift deposits into two underlying bedrock hydro- geologic units: the St Peter aquifer, and a rubble zone between the St. Peter and Prairie du Chien-Jordan aquifers. Shallow ground-water flow in the near-surface gray and upper red tills and sand and gravel outwash aquifer discharges to springs along the edge of the river. Ground water flowing through the rubble zone and upper part of the Prairie du Chien-Jordan aquifer probably discharges through alluvial deposits to the river. In study area 2, along the Minnesota River between Eagan and Bloomington, almost 200 feet of post-glacial alluvium, glaciofluvial sand and gravel, Pleistocene lake deposits, and peat fill a bedrock valley under the present-day Minnesota River. As much as 40 feet of post-glacial peat, silty clay, clay, and muck lie near the river-valley walls. Confining units beneath the river channel impede the discharge of ground water from the underlying Prairie du Chien-Jordan aquifer to the river. Ground water discharges to wetlands, lakes, and springs along both the north and south side of the river. Along the Mississippi River at Minneapolis about 5 miles upstream of the confluence of the Minnesota and Mississippi Rivers, the Mississippi River lies in a post-glacial valley cut through thin glacial drift into the St. Peter aquifer. Beneath the river, ground water flows from the St. Peter aquifer through the overlying post-glacial ailuvium to the Mississippi River. No confining unit separates the St. Peter aquifer and the river.

    Temporal and spatial variability in wetland water-quality variables were examined for twenty-one wetlands in the Minneapolis/St. Paul metropolitan area and eighteen wetlands in adjacent Wright County. Wetland water quality was significantly affected by contact with the sediment (surface water vs. groundwater), season, degree of hydrologic isolation, wetland class, and predominant land-use in the surrounding watershed (p<0.05). Between years, only nitrate and particulate nitrogen concentrations varied significantly in Wright County wetland surface waters. For eight water-quality variables, the power of a paired before-and-after comparison design was greater than the power of a completely randomized design. The reverse was true for four other water-quality variables. The power of statistical tests for different classes of water-quality variables could be ranked according to the predominant factors influencing these: climate factors>edaphic factors>detritivory>land-use factors>biotic-redox or other multiple factors.For two wetlands sampled intensively, soluble reactive phosphate and total dissolved phosphorus were the most spatially variable (c.v.=76-249%), while temperature, color, dissolved organic carbon, and DO were least variable (c.v.=6-43%). Geostatistical analyses demonstrated that the average distance across which water-quality variables were spatially correlated (variogram range) was 61-112% of the mean radius of each wetland. Within the shallower of the two wetlands, nitrogen speciation was explained as a function of dissolved oxygen, while deeper marsh water-quality variables were explained as a function of water depth or distance from the wetland edge. Compositing water-quality samples produced unbiased estimates of individual sample means for all water quality variables examined except for ammonium. PMID:24198069

    Introduction The US Department of Agriculture has stocking criteria for healthy foods among Supplemental Nutrition Assistant Program (SNAP)-authorized retailers. Increased access to healthy food could improve diet quality among SNAP participants, which has implications for chronic disease prevention. The objective of this study was to quantify healthy foods stocked in small-size to mid-size retailers who are authorized under SNAP but not under the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Methods We used formative, cross-sectional data from a large policy evaluation to conduct secondary analyses. Store audits were conducted in 2014 in 91 randomly selected, licensed food stores in Minneapolis and St. Paul, Minnesota. Supermarkets and retailers participating in WIC, which are required to stock healthy foods, were excluded as were other stores not reasonably expected to stock staple foods, such as specialty stores or produce stands. Availability of milk, fruits, vegetables, and whole-grain–rich foods was assessed. Results The 91 stores studied were corner stores, food–gas marts, dollar stores, and pharmacies. More than half carried 1 or more varieties of fat-free or low-fat milk, fresh or canned fruit, and whole-grain–rich cereal. However, only one-third stocked 1 or more varieties of fresh vegetables and only one-quarter stocked whole-grain–rich products, such as whole-grain-rich bread (26%) or tortillas (21%) or brown rice (25%). Few stores stocked at least 2 varieties of each product. Conclusions Many stores did not stock a variety of healthy foods. The US Department of Agriculture should change policies to improve minimum stocking requirements for SNAP-authorized retailers. PMID:26312380

    How extraintestinal pathogenic Escherichia coli (ExPEC) and antimicrobial-resistant E. coli disseminate through the population is undefined. We studied public restrooms for contamination with E. coli and ExPEC in relation to source and extensively characterized the E. coli isolates. For this, we cultured 1,120 environmental samples from 56 public restrooms in 33 establishments (obtained from 10 cities in the greater Minneapolis-St. Paul, MN, metropolitan area in 2003) for E. coli and compared ecological data with culture results. Isolates underwent virulence genotyping, phylotyping, clonal typing, pulsed-field gel electrophoresis (PFGE), and disk diffusion antimicrobial susceptibility testing. Overall, 168 samples (15% from 89% of restrooms) fluoresced, indicating presumptive E. coli: 25 samples (2.2% from 32% of restrooms) yielded E. coli isolates, and 10 samples (0.9% from 16% of restrooms) contained ExPEC. Restroom category and cleanliness level significantly predicted only fluorescence, gender predicted fluorescence and E. coli, and feces-like material and toilet-associated sites predicted all three endpoints. Of the 25 E. coli isolates, 7 (28%) were from phylogenetic group B2(virulence-associated), and 8 (32%) were ExPEC. ExPEC isolates more commonly represented group B2 (50% versus 18%) and had significantly higher virulence gene scores than non-ExPEC isolates. Six isolates (24%) exhibited ≥3-class antibiotic resistance, 10 (40%) represented classic human-associated sequence types, and one closely resembled reference human clinical isolates by pulsed-field gel electrophoresis. Thus, E. coli, ExPEC, and antimicrobial-resistant E. coli sporadically contaminate public restrooms, in ways corresponding with restroom characteristics and within-restroom sites. Such restroom-source E. coli strains likely reflect human fecal contamination, may pose a health threat, and may contribute to population-wide dissemination of such strains. PMID:25911488

    The St. Paul Fracture Zone (FZ) in the equatorial Atlantic is interrupted by three intratransform ridge (ITR) spreading centers. A detailed magnetic survey, corrected for the diurnal variations using a moored magnetic station, six submersible dives, and three bottom-towed video camera tracks provide data on the most eastern ITR (0°37'N, 25°27'W). Visual observations and submersible sampling displayed a high ultramafic/volcanic ratio, supporting the assumption that the ITR is in a magmatically starved state. Volcanics were mainly found on the rift valley floor from 4700 to 4000 m and as a thin cap (<160 m) on the top of the eastern rift crest (2700 m). Most of the rift walls consist essentially of serpentinized peridotites and gabbros. The magnetic data show a well-defined ridge centered anomaly. A generalized inversion method was applied to the field data to calculate the crustal equivalent magnetization, assuming that the seafloor is broken down into elementary cells of 1 × 1 × 0.5 km3 which fit the topography. The average of absolute value of equivalent magnetization is 2.7 A m-1. The width of the central normal polarity (Brunhes epoch) is wider (at least 34 km) than that indicated by the NUVEL-1 kinematic model (24.5 km). This 40% excess is believed to be significant and is thought to be the result of prolonged chemical remanent magnetization acquired during the serpentinization of peridotites. In a magmatically starved accretion segment, we suggest that peridotites could continue to acquire magnetization as long as tectonic activities facilitate the circulation of seawater in the upper mantle.

    The characterization of microbial communities within urban lake sediments may offer a promising method to observe changes in lake geochemistry due to human impact. By mapping the abundances and diversity of microorganisms through the uppermost meter of sediment in three distinctive Minneapolis-St. Paul lakes (Brownie Lake and Twin Lake, both meromictic, and oligomictic Lake McCarrons) using 16S rRNA characterization, our aim was to observe changes in microbial populations across steep geochemical and lithological gradients. Lake McCarrons underwent a process of eutrophication and a shift to bottom water anoxia beginning around 1910 due mostly to agricultural run-off. This shift greatly increased the preservation potential of seasonal sedimentation and finely laminated varve accumulation. The onset of meromixis in Brownie Lake in ~1915 is abrupt and has been attributed to a sudden drop in water level. Twin Lake is perennially meromictic due to the topography of the watershed. The three lakes were sampled by collecting freeze cores in July, 2012 (McCarrons, Brownie) and February, 2013 (Twin) at the deepest locations beneath anoxic to hypoxic bottom waters. The cores were then subsampled with high resolution techniques at places of interest: within individual lamina, across mass flow deposits, and near the onset of laminae preservation (beginning of oxygen-depleted bottom waters). Terminal Restriction Fragment Length Polymorphism (T-RFLP) allows for comparison of the microbial assemblages throughout the sediment columns of each lake and from lake to lake, with a focus on the horizons mentioned previously. The microbial assemblages present in specific horizons are often introduced via sedimentation and are partially derived from community composition at the time of sedimentation. T-RFLP analyses are complemented by mineralogical and lithological descriptions. The lakes have each been subject to their own set of variables and inputs. Brownie Lake contains high levels of

    The Franconia-Ironton-Galesville aquifer is a consolidated sandstone, approximately 60 m thick, the top of which is approximately 180 m below the land surface. It is confined above by the St. Lawrence Formation--a dolomitic sandstone 8-m thick--and below by the Eau Claire Formation--a shale 30-m thick. Initial hydraulic testing with inflatable packers indicated that the aquifer has four hydraulic zones with distinctly different values of relative horizontal hydraulic conductivity. The thickness of each zone was determined by correlating data from geophysical logs, core samples, and the inflatablepacker tests.

    Director Paul F. Bikle, seated at his desk at NASA's Flight Research Center (FRC) in 1959, the year of his appointment. The FRC became the Dryden Flight Research Center in 1976, after Paul's retirement. Paul F. Bikle became Director of the National Aeronautics and Space Administration's Flight Research Center at Edwards, California, on September 15, 1959, retaining that title until April 27, 1971, when he requested to be placed in an advisory role until his retirement on May 31, 1971. He was formerly technical director of the Air Force Flight Test Center at Edwards. During his nearly 12 years with NASA he was responsible for several major aeronautical research programs, including those involving the highly successful rocket-powered X-15, the supersonic XB-70, the fleet of wingless lifting bodies that contributed to development of the Space Shuttles, and the Lunar Landing Research Vehicle that paved the way for successful landings by Apollo astronauts on the moon's surface. Paul earned a Bachelor's degree in aeronautical engineering from the University of Detroit in 1939. He first worked for Taylorcraft Aviation Corporation in Ohio before beginning his government service career in 1940 at Wright Field, Ohio. In his first 20 years of civilian service in aeronautical engineering, he was author of more than 40 technical publications. Bikle was a veteran of 23 years of soaring. He established two world soaring records on February 25, 1961, achieving an altitude of 46,269 feet and a total-altitude-gained mark of 42,305 feet. Both marks were certified by the Soaring Society of America, National Aeronautic Association, and the Federation Aeronautique Internationale. Bikle held those records for sailplanes for more than 20 years. In July, 1962, Paul was awarded the NASA Medal for Outstanding Leadership. NASA cited him for his part in directing the successful X-15 flight operations and research activities. Paul was also a Fellow in the American Institute of Aeronautics and

    Brown, Matthew J; Kidd, Ian James

    2016-06-01

    This volume is devoted to a reappraisal of the philosophy of Paul Feyerabend. It has four aims. The first is to reassess his already well-known work from the 1960s and 1970s in light of contemporary developments in the history and philosophy of science. The second is to explore themes in his neglected later work, including recently published and previously unavailable writings. The third is to assess the contributions that Feyerabend can make to contemporary debate, on topics such as perspectivism, realism, and political philosophy of science. The fourth and final aim is to reconsider Feyerabend's place within the history of philosophy of science in the light of new scholarship. PMID:27269258

  19. Creating breakthroughs at 3M.

    PubMed

    von Hippel, E; Thomke, S; Sonnack, M

    1999-01-01

    Most senior managers want their product development teams to create break-throughs--new products that will allow their companies to grow rapidly and maintain high margins. But more often they get incremental improvements to existing products. That's partly because companies must compete in the short term. Searching for breakthroughs is expensive and time consuming; line extensions can help the bottom line immediately. In addition, developers simply don't know how to achieve breakthroughs, and there is usually no system in place to guide them. By the mid-1990s, the lack of such a system was a problem even for an innovative company like 3M. Then a project team in 3M's Medical-Surgical Markets Division became acquainted with a method for developing breakthrough products: the lead user process. The process is based on the fact that many commercially important products are initially thought of and even prototyped by "lead users"--companies, organizations, or individuals that are well ahead of market trends. Their needs are so far beyond those of the average user that lead users create innovations on their own that may later contribute to commercially attractive breakthroughs. The lead user process transforms the job of inventing breakthroughs into a systematic task of identifying lead users and learning from them. The authors explain the process and how the 3M project team successfully navigated through it. In the end, the team proposed three major new product lines and a change in the division's strategy that has led to the development of breakthrough products. And now several more divisions are using the process to break away from incrementalism. PMID:10621267

    Asmus, John F.

    2009-07-01

    Ever since the dawn of the 20th Century there has been a universal consensus that Alphonse Mucha launched the sensation that became known as Art Nouveau. This event was associated with the appearance of his Gismonda poster promoting the Sarah Bernhardt play of that name in Paris in 1894. At an estate sale in 1954 a small collage bearing a likeness of Mucha's Gismonda was offered. It had been fabricated by gluing slivers cut from sixty postage stamps to a 20cm ceramic tile. Digital computer image enhancement was applied to the collage design, initials on a walking stick from the same estate collection, and the Mucha poster. These geometrical analyses revealed that the collage is more detailed than the Mucha "original". This led to our hypothesis that the famous poster was a hasty photographic plagiarism of the intricate ceramic-tile collage. Image analyses of the initials on the companion walking stick revealed conformity with the famous enigmatic "P GO" monogram of Paul Gauguin. We conclude that Gauguin rather than Mucha created the Gismonda composition. Historical evidence suggests that, while Gauguin was in Brittany recovering from injuries sustained in a fistfight, Annah la Javanese stole his possessions and took them to Paris where her next lover, Mucha, copied the collage and presented it as his original poster design.

  1. Saint Paul Energy Park: the potential for district heating

    SciTech Connect

    Lee, C.; Kron, R.; Davis, H.

    1980-03-01

    The results of ANL's study of the energy and economic aspects of using district heating in the St. Paul Energy Park are summarized. The Energy Park is a 6 million ft/sup 2/ residential, commercial office, and light industrial complex to be built in the midway area of St. Paul, Minnesota. Space heating and cooling design loads for the park were calculated assuming that the ASHRAE's 90-75 energy-conserving construction standards would be used in constructing the park's buildings. Based in part on this assumption, ANL estimated the costs and energy use characteristics of six possible energy system options for supplying Energy Park's space heating, space cooling, and domestic hot water heating needs. The results indicate that in today's economy, a central heating and cooling plant with natural gas boilers and electrically driven centrifugal chillers with thermal storage has good potential for energy and economic savings and clearly merits further consideration.

Hooper (Ed.), Computational Methods in Classical and Quantum Physics, Advance Publications Ltd, 1976, pp. 206-228; R. Hockney, J. Eastwood, Computer Simulation using Particles, McGraw-Hill, 1981 (Student Ed., Adam-Hilger, 1988)] for boundary integral and N-body calculations. It gives O(NlogN) complexity and O(N) storage of action-at-a-distance convolution sums for non-uniform distributions of sources and for any displacement invariant Green's function. It gives optimal accuracy and, unlike the Fast Multipole Method, it does not suffer from low frequency breakdown problems.

    In this article, former US Senator Paul Simon notes that, in his lifetime, the population of the world has tripled and is expected to quadruple. Among the effects of this population growth will be a 55% increase in nitrate emissions that will feed algae and compromise fish supplies. The US was extremely short-sighted when it reduced funding for the international family planning (FP) programs that benefit all nations. False accusations that the UN Population Fund (UNFPA) operates with a "bloated bureaucracy" ignore the fact that this agency has only 166 employees. More appropriate criticism would assert that the task the UNFPA is trying to accomplish is too important and too vast for such a small staff. Without FP programs, earth would now have to support an additional 400 million people. While contraceptive use by married women in developing countries has increased from 10% in 1965 to above 50% today and life expectancy is increasing, we must recognize the fact that we are currently unable to provide most of the world's population with safe water and sanitation and that increased population size will only exacerbate this problem. Encouraging voluntary FP is humanitarian and prudent and will help protect the entire population of the world. PMID:12294691

    The National Library of Medicine has also just posted a Web site on Linus Pauling in its Profiles of Science series. While by no means as rich as the various Oregon State University sites, it is well worth visiting. There are texts of various speeches (including his Nobel address), many downloadable photographs, correspondence (including a poignant letter to James Watson and Francis Crick concerning their "rival" structures for DNA), and much else besides. There is a certain irony in Linus Pauling being honored by the National Library of Medicine. Ever since his 1949 presidential address to the American Chemical Society, and perhaps earlier, Pauling had been at loggerheads, sometimes acrimoniously so, with the medical establishment. It is easy to imagine him somewhere in the timeless infinitude of the empyrean sporting his characteristic ear-to-ear grin.

    Paul Barr, an extragalactic astronomer and spacecraft mission planner, died on 19 October 2005 at his home in Noordwijk, the Netherlands, at the age of 50. Although his scientific interests ranged from AGN to X-ray binaries, he will perhaps best be remembered for his mission planning skills on EXOSAT, ISO, and Integral. Many hundreds of observers have benefited from his ability to juggle seemingly impossible observing constraints and arrive at the optimum observing program. A rare talent. Barr was born in Sunderland, England, on 28 July 1995. After attending Saint Aidans Grammar School, where his father was the headmaster, he obtained his Bachelors Degree in astronomy from the University of London (June 1976) before moving to the Mullard Space Science Laboratory. There he obtained his Doctorate in X-ray astronomy in February 1980, using data from the Ariel V and Copernicus satellites. After a Post-Doctoral position at London University, where he did research into ultra-violet emission from AGN and X-ray binaries using IUE, Paul joined ESA in 1983. He worked on a wide range of missions including EXOSAT, ISO, and Integral. These observatories spanned the wavelength range from the Infra-red to the gamma-ray, giving insight into Paul's flexibility and ability to contribute in many areas. On ISO, Paul oversaw the scientific development and use of the very successful observation scheduling system — this topic became his specialty. As ISO operations became routine, he took up the challenge of space-borne gamma-ray astronomy and moved in 1997 to Integral where he worked in the Science Operation Centre (ISOC), at ESTEC in the Netherlands, as senior mission planner. He worked with the gamma-ray imager (IBIS) instrument team to ensure that operations of their instrument were properly supported by ESA and supported preparations of announcements of opportunity. In early 2005 the ISOC moved to Europe's Space Astronomy Centre (ESAC) just outside Madrid, Spain. Paul, however

    The symbols k and q denote wave numbers in scattering experiments as well as in NMR imaging. Their exploration in NMR is intimately linked to the legacy of Paul Callaghan with his books Magnetic Resonance Microscopy and Translational Dynamics & Magnetic Resonance (Oxford University Press, Oxford 1991 and 2011) placing their focus with their titles on k and q, respectively. Some aspects of k and q have been revisited in the Paul Callaghan lecture of the author at the ISMAR Conference in Shanghai in 2015, which are reviewed here. In particular, there are two definitions of q, one relating to diffusive displacement (q) and the other to coherent flow (qv). Concerning the latter, it turns out, that in the short gradient pulse limit, the common anti-phase pulsed field-gradient scheme can be replaced with schemes employing three and more gradient pulses, which derive from differentiation rules in numerical analysis. Practical gradient modulation schemes with finite gradient pulse widths follow from these to measure velocity with improved accuracy. This approach can be expanded to acceleration and higher order transport coefficients with applications to measurements of flow and potentially also restricted diffusion.

In particular, there are two definitions of q, one relating to diffusive displacement (q) and the other to coherent flow (qv). Concerning the latter, it turns out, that in the short gradient pulse limit, the common anti-phase pulsed field-gradient scheme can be replaced with schemes employing three and more gradient pulses, which derive from differentiation rules in numerical analysis. Practical gradient modulation schemes with finite gradient pulse widths follow from these to measure velocity with improved accuracy. This approach can be expanded to acceleration and higher order transport coefficients with applications to measurements of flow and potentially also restricted diffusion. PMID:27067190

  17. Paul Revere Osler: the other child

    PubMed Central

    2015-01-01

    Sir William Osler (1849–1919) is among the most honored and esteemed physicians of our time. His life, and that of his wife Grace Revere Osler (1854–1928), has been examined in great detail by historians and biographers and continues to be the subject of intensive scrutiny. Their son “Revere” (Edward Revere Osler) (1895–1917), who died in the Great War, is often mistakenly referred to as their only child. Grace had two previous pregnancies, having given birth to Paul Revere Osler, who lived but a week, early in their marriage in 1893 and to a stillborn infant during her first marriage to Dr. Samuel W. Gross in 1877. Information regarding these two events is often ill defined, cursory, or incorrect. New research provides further knowledge of these events and their impact, giving a fuller understanding and a more lucid historiography of the Oslers. PMID:25552789

  18. Charged nanodiamonds in a Paul trap

    NASA Astrophysics Data System (ADS)

    Streed, Erik

    2015-05-01

    Colloidal nanodiamonds were ionized with atmospheric electrospray and loaded into a Paul trap. Fluorescence from atom-like NV0 and NV- colour centres has been observed. The very low intrinsic absorption of bulk diamond is favourable for reducing the heating of cooled, trapped, nanodiamond ions from the surrounding blackbody radiation of the trapping apparatus. The isolated environment of the ion trap is also favourable for in-situ modification of nanodiamond to reduce absorption inducing defects through either physical or chemical processes. The presence or intentional introduction of high luminescence atom-like colour centre defects such as NV or SiV offer the prospect of direct laser cooling in nanodiamonds with low emissivity. Such laser cooled nano-ions are of interest for sympathetically cooling ions of similar charge/mass ratios that lack closed optical transitions, such as large biomolecules. ARC Future Fellow.

  20. Paul Ehrenfest and the dilemmas of modernity.

    PubMed

    van Lunteren, Frans H; Hollestelle, Marijn J

    2013-09-01

    This essay considers the highly ambivalent attitude of the Austrian-Dutch physicist Paul Ehrenfest toward contemporary developments in both science and society. On the one hand, he was in the vanguard of the quantum and relativity revolutions, supported industrialization and economic planning based on mathematical models, and, in general, cherished technocratic ideals. The essay highlights several influences that shaped his attitude in these respects, from his ties with the Philips Physics Laboratory and his sojourns in the United States to the utopian visions of H. G. Wells. On the other hand, he was extremely worried about the harmful consequences of contemporary changes in science and society, such as specialization, the growing pace of city life, and the increasing dependence on modern technologies, be they material or mathematical. In this regard, he agreed with cultural critics such as Max Nordau, Henri Bergson, Ostwald Spengler, and Ludwig Klages. Rather than attempting to solve this paradox, the essay suggests that this kind of ambiguity characterized a great deal of innovative science in the period. PMID:24341262

  1. Paul Sollier, Pierre Janet, and their vicinity.

    2014-01-01

    Paul Sollier (1861-1933) and Pierre Janet (1859-1947) shared the same fate: achieving fame during their lives, then slipping into obscurity. However, their work is highly relevant for describing and explaining hysteria in the tradition of Jean-Martin Charcot (1825-1893). Both men had their teacher's clinical perspicacity, which enabled them to accumulate detailed clinical and psychological descriptions. These were published in books that achieved success in their day. From his descriptions, Sollier deduced a pathophysiology of hysteria in which a psychic inhibition led to a functional deficit in sensory-motor areas. This is partially confirmed by current functional brain imaging techniques. As for Janet, he developed concepts which are still valid today, involving personality dissociation, what he referred to as 'fixed ideas', and the subconscious. Sollier and Janet both saw hysteria as a response to the trigger of an emotional shock, specific to certain personalities. While the fundamental work by Joseph Babinski (1857-1932) on hysterical paralysis did much to enrich neurological semiology, Sollier contributed a novel description of the pathophysiology of hysteria, and Janet elucidated its psychopathological mechanisms.

  2. Paul Sollier: the first clinical neuropsychologist.

    PubMed

    Bogousslavsky, Julien; Walusinski, Olivier

    2011-01-01

    Paul Sollier (1861-1933) is perhaps the most unjustly forgotten follower of Jean-Martin Charcot. He studied with Désiré Bourneville, Charcot's second interne, and was considered by Léon Daudet as the cleverest collaborator of Charcot, along with Joseph Babinski. Charcot assigned him the task of summarizing the theories on memory, which led to two major books, in 1892 and 1900, that anticipated several contemporary concepts by several decades. In 1905-1906, the novelist Marcel Proust spent 6 weeks with Sollier in his sanatorium at Boulogne-Billancourt, and it is now obvious that several of Proust's ideas on involuntary memories which appear inside In Search of Lost Time (published 8 years later) had been inspired by Sollier's theories on the 'surge of reminiscences'. Sollier also designed the framework which led to the intellectual quotient (IQ) and made interesting studies on hysteria and behavioral issues in neurological diseases, activities that may make him the first modern clinical neuro psychologist. Sollier was also the first to correlate clinical findings with neurophysiological concepts, which makes him a precursor of our current approach to neurology and psychiatry. PMID:20938150

  3. The 'scientific artworks' of Doctor Paul Richer.

    PubMed

    Ruiz-Gómez, Natasha

    2013-06-01

    This article examines the little-known sculptures of pathology created by Doctor Paul Richer (1849-1933) in the 1890s for the so-called Musée Charcot at the Hôpital de la Salpêtrière in Paris. Under the direction of Doctor Jean-Martin Charcot (1825-1893), one of the founders of modern neurology, Richer was the head of the hospital's museum of pathological anatomy, as well as the Salpêtrière's resident artist. His 'series of figural representations of the principal types of nervous pathology' included busts of patients suffering from labio-glosso-laryngeal paralysis and myopathy, as well as sculptures depicting patients with Parkinson's disease and juvenile hypothyroidism. These patient portraits were seen as objective, while also paradoxically providing an alternative to mechanical media, such as the photograph and the cast, by permitting the doctor's intervention in not only controlling and animating the sitter, but also emphasising the patient's symptoms. This was a new kind of medical specimen: the 'scientific artwork', as they were called by a contemporary. This phrase, far from being an oxymoron, indicates the purposive collapse of the objective ('scientific') and subjective ('artistic') binary in Richer's sculptures of pathology. Through a detailed examination of three of Richer's works, this article problematises the categories traditionally used to describe, analyse and understand medical imagery and complicates our understanding of the relationship between science and art at the end of the nineteenth century.

  2. Strategic stories: how 3M is rewriting business planning.

    PubMed

    Shaw, G; Brown, R; Bromiley, P

    1998-01-01

    Virtually all business plans are written as a list of bullet points. Despite the skill or knowledge of their authors, these plans usually aren't anything more than lists of "good things to do." For example: Increase sales by 10%. Reduce distribution costs by 5%. Develop a synergistic vision for traditional products. Rarely do these lists reflect deep thought or inspire commitment. Worse, they don't specify critical relationships between the points, and they can't demonstrate how the goals will be achieved. 3M executive Gordon Shaw began looking for a more coherent and compelling way to present business plans. He found it in the form of strategic stories. Telling stories was already a habit of mind at 3M. Stories about the advent of Post-it Notes and the invention of masking tape help define 3M's identity. They're part of the way people at 3M explain themselves to their customers and to one another. Shaw and his coauthors examine how business plans can be transformed into strategic narratives. By painting a picture of the market, the competition, and the strategy needed to beat the competition, these narratives can fill in the spaces around the bullet points for those who will approve and those who will implement the strategy. When people can locate themselves in the story, their sense of commitment and involvement is enhanced. By conveying a powerful impression of the process of winning, narrative plans can mobilize an entire organization. PMID:10179653

    Damon Paul Simonelli died unexpectedly on 1 December 2004 after he collapsed of heart failure at his home near Pasadena, California. Damon led pioneering studies in the scientific exploration of the satellites of the Solar System with spacecraft. He was a longtime member of the AAS's Division for Planetary Sciences community. Only two weeks before his death he attended the 2004 DPS meeting in Louisville where he presented a paper on the surface roughness of Phoebe based on Cassini observations. Damon was born in the Bronx, New York, on 15 August 1959. His father, Aldo Simonelli (d. 1990), was a clarinetist for the New York City Opera Company, and his mother, Alice Kennard Simonelli, was a secretary. His parents met while they were both students at the Julliard School. Family history has it that Damon's mother was an opera student, but she ruined her voice after singing when she had the flu. By junior high school, Damon had become a master at convincing his mother to wake him up at 3 AM to watch televised moonwalks, and to allow the entire family to view Star Trek episodes at the dinner table. Damon graduated from the Bronx High School of Science in 1976, with a composition on the New York State Regents exam that mentioned the significance of bicentennial toilet bowl lids. In addition to placing great emphasis on humor, the Simonelli family valued education. Damon's younger sister Danelle graduated from Vassar College and has served many years as a U. S. Park Ranger at Liberty Island. Damon graduated with a BA summa cum laude in physics from Cornell in 1980, where he had begun working with Carl Sagan. Damon had painstakingly gone through all the Viking images to look for any possibility of sentient life on Mars (he didn't find any). Perhaps the arrival of data from the first great explorers of the outer Solar System - Voyagers 1 and 2 - convinced Damon to continue at Cornell with Joe Veverka. While at Cornell, Damon began his pioneering work on the use of

  7. Concerning neutral flux shielding in the U-3M torsatron

    SciTech Connect

    Dreval, N. B.

    2015-03-15

    The volume of the torsatron U-3M vacuum chamber is about 70 m{sup 3}, whereas the plasma volume is about 0.3 m{sup 3}. The large buffer volume of the chamber serves as a source of a substantial neutral flux into the U-3M plasma. A fraction of this flux falls onto the torsatron helical coils located in front of the plasma, due to which the dynamics of neutral influx into the plasma modifies. The shielding of the molecular flux from the buffer volume into the plasma is estimated using numerical calculations. Only about 10% of the incident flux reaches the plasma volume. Estimates show that about 20% of atoms escape beyond the helical coils without colliding with them. Under these conditions, the helical coils substantially affect the neutral flux. A discharge regime with a hot low-density plasma produced by a frame antenna is considered. The spatial distribution of the molecular density produced in this regime by the molecular flux from the chamber buffer volume after it has passed between the helical coils is calculated. The contributions of the fluxes emerging from the side and inner surfaces of the helical coils are considered. The calculations show that the shape of the spatial distribution of the molecular density differs substantially from the shape of the magnetic surfaces.

    The 3M Company has developed a high-temperature low-sag conductor referred to as Aluminum-Conductor Composite-Reinforced or ACCR. The conductor uses an aluminum metal matrix material to replace the steel in conventional conductors. The objective of this work is to accelerate the commercial acceptance by electric utilities of this new conductor design by testing four representative conductor classes in controlled conditions. A unique facility called the Powerline Conductor Accelerated Testing (PCAT) Facility was built at ORNL for testing overhead conductors. The PCAT has been uniquely designed for testing overhead bare transmission line conductors at high currents and temperatures after they have been installed and tensioned to the manufacturer's specifications. The ability to operate a transmission line conductor in this manner does not exist elsewhere in the United States. Four classes of ACCR cable designed by the 3M Company have been successfully test at ORNL small, medium, large and small/compact. Based on these and other manufacturer tests, the 3M Company has successfully introduced the ACCR into the commercial market and has completed over twenty installations for utility companies.

  10. Linus Pauling's "molecular diseases": between history and memory.

    Strasser, Bruno J

    2002-08-30

    In 1949, Linus Pauling and his collaborators published a study in the journal Science entitled "Sickle Cell Anemia, a Molecular Disease." In this now classic study, they showed that hemoglobin from patients suffering from sickle cell anemia has a different electrical charge than hemoglobin from healthy individuals. This result demonstrated for the first time that an abnormal protein could be causally linked to a disease, and that genes determined the structure of proteins. This report made headline news and had a powerful impact on both the biomedical community and the general public. Fifty years later, this study is discussed in almost every medical and biological textbook and has became a favorite example in editorials to illustrate the progress of biomedical research. This article explores the history of Pauling's sickle cell anemia and its subsequent integration in different collective memories, up to the present day. It also discusses the function of the collective memories of Pauling's discovery for contemporary biomedical research. PMID:12400054

With Doppler backscattering (DBS) the basic properties of the GAM such as frequency, conditions for the GAM existence and the GAM radial location have been identified. The two-frequency Doppler reflectometer system was employed to reveal an interplay between low frequency sheared poloidal rotation, ambient turbulence level and the GAM intensity. Bicoherence analysis of the DBS data evidences the presence of a nonlinear interaction between the GAM and plasma turbulence.

  13. 3M corporate incinerator environmental monitoring study and risk analysis

    Stevens, J.B.; Elnabarawy, M.T.; Pilney, J.

    1998-12-31

    A one-year multi-media environmental monitoring study was performed around the 3M Cottage Grove Facility. Particulate metals from the 3M Corporate hazardous waste incinerator were the focus of the study. Two environmental media were of primary interest: area soil sampling was conducted to investigate the impact of past incinerator emissions on the environment, and ambient air monitoring was conducted to address current impacts. Over 180 soil samples were taken from both agricultural and forested land in the vicinity of the Facility. More than 25 chemical parameters were then quantified in the samples. The potential impacts of past emissions from the incinerator were assessed by comparing chemical concentrations from locations where incinerator impacts were expected to be greatest (based on air dispersion modeling) to chemical concentrations in matched samples from sites expected to be least impacted. The ambient air monitoring network consisted of six stations. Source-receptor modeling was used to determine the most likely contribution of the incinerator and six additional major area sources for the air monitoring (i.e. filter) data at each station.

  16. Dinosaur extinction: closing the ‘3 m gap’

    Lyson, Tyler R.; Bercovici, Antoine; Chester, Stephen G. B.; Sargis, Eric J.; Pearson, Dean; Joyce, Walter G.

    2011-01-01

    Modern debate regarding the extinction of non-avian dinosaurs was ignited by the publication of the Cretaceous–Tertiary (K–T) asteroid impact theory and has seen 30 years of dispute over the position of the stratigraphically youngest in situ dinosaur. A zone devoid of dinosaur fossils reported from the last 3 m of the Upper Cretaceous, coined the ‘3 m gap’, has helped drive controversy. Here, we report the discovery of the stratigraphically youngest in situ dinosaur specimen: a ceratopsian brow horn found in a poorly rooted, silty, mudstone floodplain deposit located no more than 13 cm below the palynologically defined boundary. The K–T boundary is identified using three criteria: (i) decrease in Cretaceous palynomorphs without subsequent recovery, (ii) the existence of a ‘fern spike’, and (iii) correlation to a nearby stratigraphic section where primary extraterrestrial impact markers are present (e.g. iridium anomaly, spherules, shocked quartz). The in situ specimen demonstrates that a gap devoid of non-avian dinosaur fossils does not exist and is inconsistent with the hypothesis that non-avian dinosaurs were extinct prior to the K–T boundary impact event.

    1987-06-01

    The population of St Lucia was 123,000 in 1986, with an annual growth rate of 2%. The infant mortality rate stands at 22.2/1000 live births, and life expectancy is 70.3 years for males and 74.9 years for females. The literacy rate is 78%. St Lucia's labor force is allocated as follows: agriculture, 36.6%; industry and commerce, 20.1%; and services, 18.1%. The gross national product (GNP) was US$146 million in 1985, with an annual growth rate of 3% and a per capita GNP of $1071. St Lucia is a parliamentary democracy modeled on the British Westminster system. The island is divided into 16 parishes and 1 urban area (the capital, Castries). St Lucia is currently a politically stable country, although the high level of youth unemployment is a cause for concern. Ongoing stability may depend on the government's ability to provide services such as jobs and housing. The economy has evolved from a monocrop sugar plantation type to a diversified economy based on agriculture, industry, and tourism. Agriculture, dominated by the banana industry, is characterized by the participation of a large number of small and medium-sized enterprises. Industry is being encouraged through the provision of incentives such as tax rebates. The government is attempting to maintain a sound investment climate through a tripartite dialogue with the private sector and trade unions. Overall economic policy is predicated on the attraction of sound investments, by both local and foreign entities, to accelerate the rate of economic growth, solve the unemployment problem, and generate a solid balance-of-payments position.

  19. Testing of the 3M Company ACCR Conductor

    2010-09-15

    The 3M Company has developed a high-temperature low-sag conductor referred to as Aluminum- Conductor Composite-Reinforced or ACCR. The conductor uses an aluminum metal matrix material to replace the steel in conventional conductors so the core has a lower density and higher conductivity. The objective of this work is to accelerate the commercial acceptance by electric utilities of these new conductor designs by testing four representative conductor classes in controlled conditions. Overhead transmission lines use bare aluminum conductor strands wrapped around a steel core strands to transmit electricity. The typical cable is referred to as aluminum-conductor steel-reinforced (ACSR). The outer strands are aluminum, chosen for its conductivity, low weight, and low cost. The center strand is of steel for the strength required to support the weight without stretching the aluminum due to its ductility. The power density of a transmission corridor has been directly increased by increasing the voltage level. Transmission voltages have increased from 115-kV to 765- kV over the past 80 years. In the United States, further increasing the voltage level is not feasible at this point in time, so in order to further increase the power density of a transmission corridor, conductor designs that increase the current carrying capability have been examined. One of the key limiting factors in the design of a transmission line is the conductor sag which determines the clearance of the conductor above ground or underlying structures needed for electrical safety. Increasing the current carrying capability of a conductor increases the joule heating in the conductor which increases the conductor sag. A conductor designed for high-temperature and lowsag operation requires an engineered modification of the conductor materials. To make an advanced cable, the 3M Company solution has been the development of a composite conductor consisting of Nextel ceramic fibers to replace the steel core and

  2. Detection of hydrothermal plumes along the Southeast Indian Ridge near the Amsterdam-St. Paul Plateau

    NASA Astrophysics Data System (ADS)

    Scheirer, Daniel S.; Baker, Edward T.; Johnson, Kevin T. M.

    A new self-contained profiling instrument, attached to 91 lowerings of waxcores and dredges along a 1600 km stretch of the Southeast Indian Ridge, found six sites having optical back-scatter anomalies indicative of hydrothermal plumes from high-temperature seafloor venting. At five other sites, back-scatter anomalies were less distinct, and at the remaining sites, anomalies were absent. These are the first documented hydrothermal sites along this intermediate-rate spreading center and are among the very few yet discovered in the Indian Ocean basin. Some profiles exhibit complex back-scatter anomalies suggestive of multiple sources of seafloor discharge. At one site, near-bottom temperature anomalies of ∼0.1°C and the recovery of a vent-specific barnacle provide the first precise seafloor location of active venting in the deep Indian Ocean. Although this study is only reconnaissance in nature, venting along this portion of the SEIR appears to be significantly less than predicted by global correlations of plume incidence as a function of spreading rate. Nevertheless, these sites may be important as biological connections between distinct faunal assemblages of Atlantic and Pacific vent fields.

    We experimentally demonstrate the feasibility of an aqueous Paul trap using a proof-of-principle planar device. Radio frequency voltages are used to generate an alternating focusing/defocusing potential well in two orthogonal directions. Individual charged particles are dynamically confined into nanometer scale in space. Compared with conventional Paul traps working in frictionless vacuum, the aqueous environment associated with damping forces and thermally induced fluctuations (Brownian noise) exerts a fundamental influence on the underlying physics. We investigate the impact of these two effects on the confining dynamics, with the aim to reduce the rms value of the positional fluctuations. We find that the rms fluctuations can be modulated by adjusting the voltages and frequencies. This technique provides an alternative for the localization and control of charged particles in an aqueous environment. PMID:21606331

    Trapping ions in Paul traps require high radio frequency voltages, which are generated using resonators. When operating traps in a cryogenic environment, an in-vacuum resonator showing low loss is crucial to limit the thermal load to the cryostat. In this study, we present a guide for the design and production of compact, shielded cryogenic resonators. We produced and characterized three different types of resonators and furthermore demonstrate efficient impedance matching of these resonators at cryogenic temperatures.

    2011-03-01

    Paul M. Kintner Jr., who died on 16 November 2010 of pancreatic cancer, was a pioneer in studies of Earth's space environment and of space weather. His discoveries about plasma waves, wave-particle interactions, nonlinear structures, irregularities, and radio wave propagation in random media revealed how heavy ions are injected into the magnetosphere and characterized the sometimes catastrophic effects of scintillations produced in the ionosphere on satellite navigation systems (e.g., the Global Positioning System (GPS)). Paul, a professor of electrical and computer engineering at Cornell University, pioneered the use of multiple-sensor electric field and plasma wave measurements on sounding rockets and satellites and used these sensors (together the multiple sensors are sometimes called a plasma wave interferometer) to characterize plasma waves by their wavelengths and wave vectors and to identify new solitary structures in space plasmas and describe their speed, shape, and size. This interferometer was particularly useful in investigating transverse ion acceleration in the polar ionosphere. In a decisive sounding rocket experiment, Sounding of the Cleft Ion Fountain Energization Region (SCIFER), in 1995 at 1400 kilometers over Svalbard, Norway, Paul showed that the principal source of this acceleration (the source of mass in the magnetosphere) is short-wavelength broadband waves whose frequencies are determined primarily by Doppler broadening. He is also credited with discovering lower hybrid solitary structures and describing them as rotating modes in magnetic field-aligned density cavities that produce transverse ion acceleration. He extended the approach to higher frequencies and was the first to measure the speed and shape of electron solitary holes (Bernstein-Greene-Kruskal (BGK) modes).

    PubMed Central

    2014-01-01

    Inductors, transmission lines, and Tesla transformers have been modeled with lumped-element equivalent circuits for over a century. In a well-known paper from 1904, Paul Drude predicts that the mutual inductance for an unloaded Tesla transformer should be nonreciprocal. This historical curiosity is mostly forgotten today, perhaps because it appears incorrect. However, Drude's prediction is shown to be correct for the conditions treated, demonstrating the importance of constraints in deriving equivalent circuits for distributed systems. The predicted nonreciprocity is not fundamental, but instead is an artifact of the misrepresentation of energy by an equivalent circuit. The application to modern equivalent circuits is discussed.

    The St. Petersburg paradox refers to a gamble of infinite expected value, where people are likely to spend only a small entrance fee for it. There is a huge volume of literature that mostly concentrates on the psychophysics of the game; experiments are scant. Here, rather than focusing on the psychophysics, we offer an experimental, "physical" solution as if robots played the game. After examining the time series formed by one billion plays, we: confirm that there is no characteristic scale for this game; explicitly formulate the implied power law; and identify the type of α-stable distribution associated with the game. We find an α = 1 and, thus, the underlying distribution of the game is a Cauchy flight, as hinted by Paul Samuelson.

    During his distinguished 37-year career as a research physicist at the Honeywell Research Center in Minneapolis, Minnesota, Dr. Paul W. Kruse (1927-2012) played leadership roles in two disruptive infrared detector technologies, the narrow-gap semiconductor alloy HgCdTe and the silicon CMOS-based microbolometer array, both of which revolutionized the worldwide infrared detector industry. He served on numerous government advisory boards and panels, including the Army Scientific Advisory Panel and the Army Science Board, for which he received the Outstanding Civilian Service Medal. After retiring for Honeywell in 1993, he remained active in the infrared detector field in several roles: as a successful small-business entrepreneur, as an author of two books, and as a SPIE lecturer. His books, papers and lectures have educated new generations of workers in the infrared detector industry. His career, a model for industrial research physicists, has had major and permanent impacts on the worldwide infrared detector industry. This paper is a summary of the career of Paul W. Kruse, as well as a tribute to that career and its lasting legacy.

  1. Perimeter ring currents in benzenoids from Pauling bond orders.

    It is shown that the ring currents in perimeter hexagonal rings of Kekulean benzenoids, as estimated within the Randić conjugated-circuit model, can be calculated directly without tedious pairwise comparison of Kekulé structures or Kekulé counting for cycle-deleted subgraphs. Required are only the Pauling bond orders of perimeter bonds and the number of Kekulé structures of the benzenoid, both readily available from the adjacency matrix of the carbon skeleton. This approach provides easy calculation of complete current maps for benzenoids in which every face has at least one bond on the perimeter (as in the example of cata-condensed benzenoids), and allows qualitative evaluation of the main ring-current contributions to (1)H chemical shifts in general benzenoids. A combined Randić-Pauling model for correlation of ring current and bond length through bond order is derived and shown to be consistent with resilience of current under bond alternation.

  6. Historical antecedents to the philosophy of Paul Feyerabend.

    PubMed

    Munévar, Gonzalo

    2016-06-01

    Paul Feyerabend has been considered a very radical philosopher of science for proposing that we may advance hypotheses contrary to well-confirmed experimental results, that observations make theoretical assumptions, that all methodological rules have exceptions, that ordinary citizens may challenge the judgment of experts, and that human happiness should be a key value for science. As radical as these theses may sound, they all have historical antecedents. In defending the Copernican view, Galileo exemplified the first two; Mill, Aristotle and Machiavelli all argued for pluralism; Aristotle gave commonsense reasons for why ordinary citizens may be able to judge the work of experts; and a combination of Plato's and Aristotle's views can offer strong support for the connection between science and happiness.

    2004-04-01

    In 2002 physicists around the world celebrated the centenary of the birth of Paul Dirac, OM, FRS, Nobel Laureate, who was one of the greatest physicists of the 20th century. He made towering contributions to the formulation of quantum mechanics and he was one of the principal creators of quantum field theory. In 1928 he combined relativity and quantum mechanics in the Dirac equation, which provides a natural description for the spin of the electron and which led to the prediction, by Dirac himself, of the existence of anti-matter. In this article I try to explain, in the simplest terms, these major contributions to physics and to give some flavour of the man himself.

    2016-06-01

    I summarize certain aspects of Paul Feyerabend's account of the development of Western rationalism, show the ways in which that account is supposed to run up against an alternative, that of Karl Popper, and then try to give a preliminary comparison of the two. My interest is primarily in whether what Feyerabend called his 'story' constitutes a possible history of our epistemic concepts and their trajectory. I express some grave reservations about that story, and about Feyerabend's framework, finding Popper's views less problematic here. However, I also suggest that one important aspect of Feyerabend's material, his treatment of religious belief, can be given an interpretation which makes it tenable, and perhaps preferable to a Popperian approach.

  9. Baring the soul: Paul Bindrim, Abraham Maslow and 'nude psychotherapy'.

    PubMed

    Nicholson, Ian

    2007-01-01

    Nude psychotherapy is one of the most flamboyant therapeutic techniques ever developed in American psychology. Largely forgotten today, the therapy was an academic and popular sensation upon its introduction in 1967. Developed by psychologist Paul Bindrim, the therapy promised to guide clients to their authentic selves through the systematic removal of clothing. This paper explores the intellectual, cultural and ethical context of nude therapy and its significance as a form of unchurched spirituality. Although nude therapy has an indisputable tabloid character, it is also rooted in a long-standing academic search for authenticity and ultimate meaning through science. Bindrim's career demonstrates the historically long-standing interweaving of spirituality and science within American psychology while simultaneously highlighting the field's extraordinary capacity for adaptive reinvention.

    Pressure, together with temperature and magnetic field, is an important thermodynamical parameter in physics. Investigating the response of a compound or of a material to pressure allows to elucidate ground states, investigate their interplay and interactions and determine microscopic parameters. Pressure tuning is used to establish phase diagrams, study phase transitions and identify critical points. Muon spin rotation/relaxation (μSR) is now a standard technique making increasing significant contribution in condensed matter physics, material science research and other fields. In this review, we will discuss specific requirements and challenges to perform μSR experiments under pressure, introduce the high pressure muon facility at the Paul Scherrer Institute (PSI, Switzerland) and present selected results obtained by combining the sensitivity of the μSR technique with pressure.

  11. Transcultural nursing: a perspective derived from Jean-Paul Sartre.

    PubMed

    Rajan, M F

    1995-09-01

    Transcultural nursing care is a well-established theoretical framework. This theory, developed by Madeleine Leininger, can have an impact on clinical practice, academic preparation and nursing research. The heightened interest in applying transcultural care and the increased need to espouse this framework have been triggered by constant population changes. This paper defines transcultural nursing care and expands its definition further by comparing and contrasting it with Jean-Paul Sartre's existentialist perspective. The two modes of existence as defined by Sartre are closely examined. Concrete examples are offered as cultural phenomena and the components of a cultural assessment are discussed and applied. The philosophical thesis is approached from a transcultural nursing perspective and existentialism is shown to serve as a foundation for transcultural nursing. The advantages and disadvantages of transcultural nursing practice and the preparation of transcultural nurses are finally addressed. PMID:7499611

  14. Genetic structure of the Caribbean giant barrel sponge Xestospongia muta using the I3-M11 partition of COI

    NASA Astrophysics Data System (ADS)

    López-Legentil, S.; Pawlik, J. R.

    2009-03-01

    In recent years, reports of sponge bleaching, disease, and subsequent mortality have increased alarmingly. Population recovery may depend strongly on colonization capabilities of the affected species. The giant barrel sponge Xestospongia muta is a dominant reef constituent in the Caribbean. However, little is known about its population structure and gene flow. The 5'-end fragment of the mitochondrial gene cytochrome oxidase subunit I is often used to address these kinds of questions, but it presents very low intraspecific nucleotide variability in sponges. In this study, the usefulness of the I3-M11 partition of COI to determine the genetic structure of X. muta was tested for seven populations from Florida, the Bahamas and Belize. A total of 116 sequences of 544 bp were obtained for the I3-M11 partition corresponding to four haplotypes. In order to make a comparison with the 5'-end partition, 10 sequences per haplotype were analyzed for this fragment. The 40 resulting sequences were of 569 bp and corresponded to two haplotypes. The nucleotide diversity of the I3-M11 partition (π = 0.00386) was higher than that of the 5'-end partition (π = 0.00058), indicating better resolution at the intraspecific level. Sponges with the most divergent external morphologies (smooth vs. digitate surface) had different haplotypes, while those with the most common external morphology (rough surface) presented a mixture of haplotypes. Pairwise tests for genetic differentiation among geographic locations based on F ST values showed significant genetic divergence between most populations, but this genetic differentiation was not due to isolation by distance. While limited larval dispersal may have led to differentiation among some of the populations, the patterns of genetic structure appear to be most strongly related to patterns of ocean currents. Therefore, hydrological features may play a major role in sponge colonization and need to be considered in future plans for management and

  16. One More Legacy of Paul F. Brandwein: Creating Scientists

    NASA Astrophysics Data System (ADS)

    2011-06-01

    This paper studies the influence of Paul F. Brandwein, author, scientist, teacher and mentor, publisher, humanist, and environmentalist, on gifted youngsters who later became scientists, based primarily on information gathered from surveys completed by 25 of his students and one colleague. It also traces his profound interactions with science educators. It illuminates the theories of Brandwein and his protégés and colleagues about the interaction of environment, schooling, and education and Brandwein's belief in having students do original research (that is, research whose results are unknown) on their way to discovering their future scientific paths. It tests Brandwein's 1955 hypothesis on the characteristics typical of the young who eventually become scientists, namely: Three factors are considered as being significant in the development of future scientists: a Genetic Factor with a primary base in heredity (general intelligence, numerical ability, and verbal ability); a Predisposing Factor, with a primary base in functions which are psychological in nature; an Activating Factor, with a primary base in the opportunities offered in school and in the special skills of the teacher. High intelligence alone does not make a youngster a scientist (p xix).

    2010-01-01

    Physician, scientist and revolutionary are the biographical aspects that had better summarize the life of Jean-Paul Marat (1743-1793). Due to the role that he played during the French Revolution, his work as a physician and scientist, prior to the events of l789, was forgotten. Marat made important contributions in the area of optics and electricity reflected in numerous publications, as well as translating Newton's Opticks (1787). Well known for his radical and aggressive ideas, his political vocation led him to embrace the revolutionary cause after the events of the Bastille. His figure was not indifferent to his contemporaries; although considered a hero by the poorest citizens, aristocrats and bourgeois considered him a cruel extremist. During the last years of his life, he suffered a cutaneous disease, the diagnosis of which is still a matter of controversy. Proposed diagnoses include eczema, seborrheic dermatitis, scabies and dermatitis herpetica, among others. Marat was assassinated by Charlotte Corday in 1793, becoming a martyr for some segments of the society that worshiped his memory. He was a man with a complex and curious personality whose figure and legacy are still a matter of discussion. PMID:20361162

  18. Paul de Kruif's Microbe Hunters and an outraged Ronald Ross.

    PubMed

    Chernin, E

    1988-01-01

    Paul de Kruif's book, Microbe Hunters, published in New York in 1926, was a romanticized medical "history," written in a breathless style, that describes the lives and works of a dozen famous figures, ranging from Leeuwenhoek to Sir Ronald Ross. Ross, who received the Nobel Prize in 1902 for his discovery that certain mosquitoes transmit malaria, resented de Kruif's personal remarks and his version of the malaria story, especially concerning the disputes with Italian workers over priorities. In a little-known polemic "review" of Microbe Hunters, Ross castigated de Kruif for statements he considered libelous. While Ross could not sue for libel across the Atlantic, his threatened action for libel forced the publisher of the British edition of Microbe Hunters to delete the chapter about Ross and one about David Bruce, Ross's countryman. de Kruif's book, a best-seller in its day and influential among the young for a generation, now seems gauche and anachronistic. While Ross seems to have been justified in some of his complaints about Microbe Hunters, the bitter tone of his reactions all but confirms de Kruif's opinion of him. Ross died in 1932 with a permanent niche in medical history; de Kruif died in 1971 and is little remembered except, perhaps, for Microbe Hunters. PMID:3293166

    Astronaut Paul W. Richards, STS-102 mission specialist, works in the cargo bay of the Space Shuttle Discovery during the second of two scheduled space walks. Richards, along with astronaut Andy Thomas, spent 6.5 hours outside the International Space Station (ISS), continuing work to outfit the station and prepare for delivery of its robotic arm. STS-102 delivered the first Multipurpose Logistics Modules (MPLM) named Leonardo, which was filled with equipment and supplies to outfit the U.S. Destiny Laboratory Module. The Leonardo MPLM is the first of three such pressurized modules that will serve as the ISS' moving vans, carrying laboratory racks filled with equipment, experiments, and supplies to and from the Station aboard the Space Shuttle. The cylindrical module is approximately 21-feet long and 15- feet in diameter, weighing almost 4.5 tons. It can carry up to 10 tons of cargo in 16 standard Space Station equipment racks. Of the 16 racks the module can carry, 5 can be furnished with power, data, and fluid to support refrigerators or freezers. In order to function as an attached station module as well as a cargo transport, the logistics module also includes components that provide life support, fire detection and suppression, electrical distribution, and computer functions. NASA's 103rd overall mission and the 8th Space Station Assembly Flight, STS-102 mission also served as a crew rotation flight. It delivered the Expedition Two crew to the Station and returned the Expedition One crew back to Earth.

    Educational components are encouraged, sometimes required, in grant-funded research. However, it is not reasonable to expect scientists to master a second field, education. The NASA Office of Space Science has included regional Broker/Facilitator centers in its ``ecosystem" (multidimensional education/outreach network) to help bridge the gap. Broker/Facilitators are to ``work with the space science community to identify high-leverage opportunities for education/outreach and help arrange collaborations between scientists and educators" (www.hq.nas.gov/office/oss/education/edprog.html). The regional center at DePaul University serves six states (IA, IL, IN, MN, MO, and WI). Full activity will begin in August 1998, when staff are in place. Initially, we expect to assist scientists who wish to develop educational plans to complement their research programs, and help find educational partners for research groups or individuals. Further services, activities, and programs are being planned; feedback from researchers and others is being sought. Progress and further details of plans will be presented.

    2012-03-01

    The professional career of Paul Nitsche reflects the contradictory path taken by a German institutional psychiatrist who was a leader in the field at the time. During the Weimar Republic he advocated improving the institutional system based on principles of psychiatric reform, but was already receptive to concepts of racial hygiene. Shortly after the National Socialists seized power, Nitsche was already an influential proponent and participant in eugenic measures in Saxony and actively involved in implementing the "Law for the Prevention of Genetically Diseased Offspring." He increasingly appraised the value of a patient according to the person's economic performance. It was also Nitsche's opinion that the consequence of this extreme rationalization of human life was to exterminate "life unworthy of life." As a T4 appointed head assessor he decided in the last instance whether thousands of people would live or die. As the Medical Director of the T4 program, he was later directly responsible for continuing the massacre as "decentralized euthanasia." At the euthanasia trial in Dresden he was condemned to death and executed in 1948. PMID:22399059

    3-M syndrome (OMIM #273750) is a rare autosomal recessive growth disorder characterized by severe pre- and post-natal growth restriction, associated with minor skeletal abnormalities and dysmorphisms. Although the 3-M syndrome is well known as a primordial dwarfism, descriptions of the prenatal growth are missing. We report a family with variable phenotypic features of 3-M syndrome and we describe the prenatal and postnatal growth pattern of two affected sisters with a novel homozygous CUL7 mutation (c.3173-1G>C), showing a pre- and post-natal growth deficiency and a normal cranial circumference.

    A power law regression equation, = 1.46(<ρ(rc)>/r)-0.19, connecting the average experimental bond lengths, , with the average accumulation of the electron density at the bond critical point, <ρ(rc)>, between bonded metal M and oxygen atoms, determined at ambient conditions for oxide crystals, where r is the row number of the M atom, is similar to the regression equation R(M-O) = 1.39(ρ(rc)/r)-0.21 determined for three perovskite crystals for pressures as high as 80 GPa. The two equations are also comparable with those, = 1.43(/r)-0.21, determined for a large number of oxide crystals at ambient conditions and = 1.39(/r)-0.22, determined for geometry optimized hydroxyacid molecules, that connect the bond lengths to the average Pauling electrostatic bond strength, , for the M-O bonded interactions. On the basis of the correspondence between the two sets of equations connecting ρ(rc) and the Pauling bond strength s with bond length, it appears that Pauling’s simple definition of bond strength closely mimics the accumulation of the electron density between bonded pairs of atoms. The similarity of the expressions for the crystals and molecules is compelling evidence that the M-O bonded interactions for the crystals and molecules 2 containing the same bonded interactions are comparable. Similar expressions, connecting bond lengths and bond strength, have also been found to hold for fluoride, nitride and sulfide molecules and crystals. The Brown-Shannon bond valence, σ, power law expression σ = [R1/(R(M-O)]N that has found wide use in crystal chemistry, is shown to be connected to a more universal expression determined for oxides and the perovskites, <ρ(rc)> = r[(1.41)/]4.76, demonstrating that the bond valence for a bonded interaction is likewise closely connected to the accumulation of the electron density between the bonded atoms. Unlike the Brown-Shannon expression, it is universal in that it holds for the M

    Paul Greengard was born in New York City in 1925. After completing high school, he served three years in the US Navy during World War II and then completed his bachelor's degree at Hamilton College where he majored in physics and mathematics. He obtained a PhD in biophysics from Johns Hopkins University in 1953 and pursued postdoctoral training with Wilhelm Feldberg at the National Institute for Medical Research in England. After eight years as head of biochemistry at Geigy, and sabbaticals at Albert Einstein College of Medicine and Vanderbilt University, he joined the Yale University faculty as a full professor of pharmacology in 1968. While he was at Yale, Greengard's laboratory performed groundbreaking research, which demonstrated a role for cyclic nucleotides, protein kinases and protein phosphatases, and their protein substrates in the regulation of synaptic transmission. In 1983, Greengard moved to The Rockefeller University, where he has since served as the Vincent Astor Professor and Head of the Laboratory of Molecular and Cellular Neuroscience. Greengard's paradigm-shifting research has continued at Rockefeller and has informed our understanding and possible treatment of a host of brain disorders, including schizophrenia, Alzheimer's disease, Parkinson's disease, and depression. He is the author of more than 950 research articles and reviews. Greengard has received numerous awards and honors, including the Nobel Prize in Physiology or Medicine in 2000, the Metropolitan Life Foundation Award for Medical Research, The National Academy of Sciences Award in Neuroscience, the Ralph W.

    1995-01-01

    In a 16-page letter which is widely viewed by women's groups as an effort to win support for the Vatican's position at the upcoming UN Conference on Women in Beijing, Pope John Paul II apologizes to women throughout the world for the church's historic complicity in their oppression. Although phrased in general terms, the letter contains language and ideas of a far more feminist tone than any previous statements or declarations made by the Pontiff. Calling for increased respect for women and sensitivity to their needs, the letter also claims that "there is an urgent need to achieve real equality in every area: equal pay for equal work, protection for working mothers, fairness in career advancements, equality of spouses with regard to family rights and recognition of everything that is part of the rights and duties of citizens in a democratic state." Recognizing women's significant achievements and sacrifices inside and outside of the home, the Pope expressed admiration for "those women of good will who have devoted their lives to defending the dignity of womanhood by fighting for their basic social, economic and political rights, demonstrating courageous initiative at a time when this was considered extremely inappropriate, the sign of a lack of femininity, a manifestation of exhibitionism, and even a sin." Although the letter heralds a new awareness in the Vatican of women's views, concerns and grievances, the Pope has not signaled any dramatic changes in official church policy: women's ordination, divorce, abortion and birth control are still considered beyond the pale of acceptability.

    Multiferroic materials has been the subject of intense research activity in recent years due to its fundamental scientific interests as well as potential to applications. A few of the recently discovered multiferroics with metal-organic-frameworks (MOFs) show a coexistence of magnetism and ferroelectricity, such as ABX3-type [NH2(CH3)2]M(HCOO)3 (M = Mn, Fe). Compared to inorganic compounds, the high tunability of organic materials in building blocks and molecular functionalities may open up new routes to lead-free compounds exhibiting strong polarization. In this work, we investigate the multiferrocity and magnetoelectric coupling of a class of perovskite MOFs [C(NH2)3]M(HCOO)3 (M = Mn, Co, Ni, Cu). The [C(NH2)3]Cu(HCOO)3 compound was predicted and experimentally shown to be a hybrid improper ferroelectric because of Jahn-Teller distortions and tilting of the organic cation. Yet it is not clear whether other compounds are also multiferroics. We synthesize single crystals of these compounds. Preliminary results of magnetic and dielectric characterization will be presented. This work is supported by DOE BES under Award # DE-SC0008147.

    Jean-Paul Marat was a French revolutionary, famously murdered in his bath by Charlotte Corday in 1793. A lesser known fact is that for over ten years he lived in Britain where he practised as a doctor. During this time he visited London, Edinburgh, Dublin and Holland. Although he had no formal medical training, he published two medical papers on gleets (gonorrhoea) and diseases of the eyes and, on the recommendation of two eminent Scottish physicians, William Buchan and Hugh James, he was granted a medical degree from the University of St Andrews. Marat left no medical legacy and his related writings were forgotten for 100 years until the rediscovery of the two medical papers, which were eventually re-published in 1892 at the instigation of James Bailey, the librarian of the Royal College of Surgeons of England. Biographies by F Chevremont (1880), Ashbee Spencer (1890) and A Cabanès (1891) had rekindled interest in this intriguing revolutionary. A study of his time in Britain and his medical works and training provide an interesting insight into the mind of a revolutionary and how his sojourn may have shaped his future political career upon his return to France in 1777.

  18. Specificity in Transition State Binding: The Pauling Model Revisited

    PubMed Central

    Amyes, Tina L.; Richard, John P.

    2013-01-01

    Linus Pauling proposed that the large rate accelerations for enzymes are due to the high specificity of the protein catalyst for binding the reaction transition state. The observation that stable analogs of the transition states for enzymatic reactions often act as tight-binding binding inhibitors provided early support for this simple and elegant proposal. We review experimental results which support the proposal that Pauling’s model provides a satisfactory explanation for the rate accelerations for many heterolytic enzymatic reactions through high energy reaction intermediates, such as proton transfer and decarboxylation. Specificity in transition state binding is obtained when the total intrinsic binding energy of the substrate is significantly larger than the binding energy observed at the Michaelis complex. The results of recent studies to characterize the specificity in binding of the enolate oxygen at the transition state for the 1,3-isomerization reaction catalyzed by ketosteroid isomerase are reviewed. Interactions between pig heart succinyl-CoA:3-oxoacid coenzyme A transferase (SCOT) and the nonreacting portions of CoA are responsible for a rate increase of 3 × 1012-fold, which is close to the estimated total 5 × 1013-fold enzymatic rate acceleration. Studies that partition the interactions between SCOT and CoA into their contributing parts are reviewed. Interactions of the protein with the substrate phosphodianion group provide a ca. 12 kcal/mol stabilization of the transition state for the reactions catalyzed by triosephosphate isomerase, orotidine 5′-monophosphate decarboxylase and α-glycerol phosphate dehydrogenase. The interactions of these enzymes with the substrate piece phosphite dianion provide a 6 – 8 kcal/mol stabilization of the transition state for reaction of the appropriate truncated substrate. Enzyme activation by phosphite dianion reflects the higher dianion affinity for binding to the enzyme-transition state complex compared

  19. Paul Ehrenfest, Niels Bohr, and Albert Einstein: Colleagues and Friends

    In May 1918 Paul Ehrenfest received a monograph from Niels Bohr in which Bohr had used Ehrenfest's adiabatic principle as an essential assumption for understanding atomic structure. Ehrenfest responded by inviting Bohr, whom he had never met, to give a talk at a meeting in Leiden in late April 1919, which Bohr accepted; he lived with Ehrenfest, his mathematician wife Tatyana, and their young family for two weeks. Albert Einstein was unable to attend this meeting, but in October 1919 he visited his old friend Ehrenfest and his family in Leiden, where Ehrenfest told him how much he had enjoyed and profited from Bohr's visit. Einstein first met Bohr when Bohr gave a lecture in Berlin at the end of April 1920, and the two immediately proclaimed unbounded admiration for each other as physicists and as human beings. Ehrenfest hoped that he and they would meet at the Third Solvay Conference in Brussels in early April 1921, but his hope was unfulfilled. Einstein, the only physicist from Germany who was invited to it in this bitter postwar atmosphere, decided instead to accompany Chaim Weizmann on a trip to the United States to help raise money for the new Hebrew University in Jerusalem. Bohr became so overworked with the planning and construction of his new Institute for Theoretical Physics in Copenhagen that he could only draft the first part of his Solvay report and ask Ehrenfest to present it, which Ehrenfest agreed to do following the presentation of his own report. After recovering his strength, Bohr invited Ehrenfest to give a lecture in Copenhagen that fall, and Ehrenfest, battling his deep-seated self-doubts, spent three weeks in Copenhagen in December 1921 accompanied by his daughter Tanya and her future husband, the two Ehrenfests staying with the Bohrs in their apartment in Bohr's new Institute for Theoretical Physics. Immediately after leaving Copenhagen, Ehrenfest wrote to Einstein, telling him once again that Bohr was a prodigious physicist, and again

    In the summer of 2006 the Green Institute started the study for the RockTenn paper mill that would evaluate the economics and supply chain reliability of wood waste and other clean biomass as a fuel for the facility. The Green Institute obtained sponsorship from a broad coalition representing the community and the project team included other consultants and university researchers specializing in biomass issues. The final product from the project was a report to: 1) assess the availability of clean biomass fuel for use at the Rock-Tenn site; 2) roughly estimate costs at various annual usage quantities; and 3) develop the building blocks for a supply chain procurement plan. The initial report was completed and public presentations on the results were completed in spring of 2007.

    Billions of rounds of small-arms ammunition were manufactured at the Twin Cities Army Ammunition Plant (TCAAP), supporting the military in three major wars. During the course of production, solvents and hazardous chemical wastes migrated into area ground water, contaminating municipal and private wells. Highlights of the overall cleanup effort have included: removal of nearly 232,000 pounds of solvents from soil using an innovative technology, soil vapor extraction; treatment of more than six billion gallons of ground water from TCAAP extraction wells; and construction of two treatment plants to purify municipal water supplies in neighboring cities. The TCAAP property includes wetlands and undisturbed natural habitat supporting an extensive variety of wildlife. Related cleanup efforts will protect a sensitive ecosystem currently sustained as a refuge despite increasing urban pressures.

    Historical records were analyzed to determine effects of population, pollution-control strategy, and other factors on water quality of the Mississippi River. Isopleths of DO (dissolved oxygen) concentrations and lines of equal stream temperature indicated periodic data could be used to guide sampling of certain critical conditions in time and space. Long-term records revealed generally mixed changes in quality in the Mississippi River. Several mean-time series were used to show seasonal variation in water quality and effects of initiation of wastewater treatment in 1938. Kendall 's tau statistical test indicated a significant increase in DO in the upper reach of the river during the period of record. If only the post-1938 period is considered, DO conditions remained fairly constant below the metropolitan plant and biochemical oxygen demand increased throughout the main-stem reach. Significant trends in stream temperature were indicated for winter periods using Kendall 's tau procedure. The Mann-Whitney statistical test gave estimates of a 98-percent confidence interval of the magnitudes of change. (Woodard-USGS)

    2007-06-01

    In November 1949, chemist Linus Pauling and three colleagues published an article on sickle-cell anemia, a study that opened up new and exciting possibilities for research into such 'molecular diseases'. Even before this celebrated publication appeared in Science, Pauling foresaw its potential benefits and announced it as a medical breakthrough: '... our structural chemistry and understanding of molecules is getting to the point where it should be of assistance in converting medicine into a real science' [Guiles, R. (1949) Discovery of blood disease called key to cancer research. The Detroit Times 13 Sep 1949, Newspaper Clippings 1949n.18, Pauling Papers.]. Their discovery--that this debilitating disorder was caused by an abnormal form of hemoglobin--was borne out of a rich mix of expertise, from Pauling's remarkable intuition to the careful experimental chemistry of his student Harvey A. Itano. It also relied upon technological innovation: a custom-made electrophoresis machine housed at the California Institute of Technology was the perfect tool to reveal fundamental chemical differences between normal and abnormal forms of hemoglobin. Not only did this work establish a new way of looking at inherited diseases, it also stimulated the mass production of the electrophoresis machine as an essential investigative and diagnostic tool. A close inspection of this case study illustrates just how Pauling ran his laboratory and helps to explain how one man could achieve so much over his lifetime. PMID:17602747

    3-M syndrome is an autosomal recessive disorder characterised by pre- and post-natal growth restriction, facial dysmorphism, normal intelligence and radiological features (slender long bones and tall vertebral bodies). It is known to be caused by mutations in the genes encoding cullin 7, obscurin-like 1 and coiled-coil domain containing 8. The mechanisms through which mutations in these genes impair growth are unclear. The aim of this study was to identify novel pathways involved in the growth impairment in 3-M syndrome. RNA was extracted from fibroblast cell lines derived from four 3-M syndrome patients and three control subjects, hybridised to Affymetrix HU 133 plus 2.0 arrays with quantitative real-time PCR used to confirm changes found on microarray. IGF-II protein levels in conditioned cell culture media were measured by ELISA. Of the top 10 downregulated probesets, three represented IGF2 while H19 was identified as the 23rd most upregulated probeset. QRT-PCR confirmed upregulation of H19 (P<0.001) and downregulation of IGF2 (P<0.001). Levels of IGF-II secreted into conditioned cell culture medium were higher for control fibroblasts than those for 3-M fibroblasts (10.2±2.9 vs 0.6±0.9 ng/ml, P<0.01). 3-M syndrome is associated with a gene expression profile of reduced IGF2 expression and increased H19 expression similar to that found in Silver-Russell syndrome. Loss of autocrine IGF-II in the growth plate may be associated with the short stature seen in children with 3-M syndrome. PMID:24148222

    2006-03-01

    At the start of the 1930s, theoretician Paul Ehrenfest spent much of his time traveling through America and Europe while engaged in a steady stream of lectures. This traveling phase coincided with a frantic and intense period of negative self-examination, financial difficulty, and various other personal concerns that would ultimately lead to his 1933 suicide. Throughout these final years, he kept up a steady correspondence with his brother Hugo, a physician based in Saint Louis. Ten years older than Paul, Hugo freely doled out frank psychological advice about subjects ranging from the proper treatment of children to the dangers of self-pity. Through a look at some of the letters exchanged between the two brothers, this talk will examine the role Hugo played during the dark final years of Paul Ehrenfest's life.

    Translational research and precision medicine are based on a profound knowledge of cellular and molecular mechanisms contributing to various physiologic processes and pathologic reactions in diverse organs. Whereas specific molecular interactions and mechanisms have been identified during the past 5 decades, the underlying principles were defined much earlier and originate from to the seminal observations made by outstanding researchers between 1850 and 1915. One of the most outstanding exponents of these scientists is Paul Ehrlich. His work resulted not only in the foundation and birth of modern hematology and immunology, but also led to the development of chemotherapy and specific targeted treatment concepts. In 2015, the Medical University of Vienna organized a memorial meeting, with the aim of honoring Paul Ehrlich's contributions to science, and to commemorate the 100th anniversary of his death. The authors of the current review served as faculty members and dedicate this paper to Paul Ehrlich and his remarkable contributions to medicine. PMID:26845587

  15. [The vitalism of Paul-Joseph Barthez (1734-1806)].

    PubMed

    Han, Hee Jin

    2010-06-30

    In The Logic of Life (1970), Francois Jacob (1920- ), Nobel Prize laureate in Physiology or Medicine (1965), proclaimed the end of vitalism based on the concept of life. More than two decades before this capital sentence condemning vitalism was pronounced, Georges Canguilhem (1904-1995), a French philosopher of medicine, already acknowledged that eighteenth-century vitalism was scientifically retrograde and politically reactionary or counter-revolutionary insofar as it was rooted in the animism of Georg Ernst Stahl (1660-1734). The negative preconception of the term 'vitalism' came to be established as an orthodox view, since Claude Bernard (1813-1878) unfairly criticized contemporary vitalism in order to propagate his idea of experimental medicine. An eminent evolutionary biologist like Ernst Mayr (1904-2005) still defended similar views in This is Biology (1997), arguing that if vitalists were decisive and convincing in their rejection of the Cartesian model (negative heuristics), however they were equally indecisive and unconvincing in their own explanatory endeavors (positive heuristics). Historically speaking, vitalists came to the forefront for their outstanding criticism of Cartesian mechanism and physicochemical reductionism, while their innovative concepts and theories were underestimated and received much less attention. Is it true that vitalism was merely a pseudo-science, representing a kind of romanticism or mysticism in biomedical science? Did vitalists lack any positive heuristics in their biomedical research? Above all, what was actually the so.called 'vitalism'? This paper aims to reveal the positive heuristics of vitalism defined by Paul.Joseph Barthez (1734-1806) who was the founder of the vitalist school of Montpellier. To this end, his work and idea are introduced with regard to the vying doctrines in physiology and medicine. At the moment when he taught at the medical school of Montpellier, his colleagues advocated the mechanism of Rene

    This article reports on the disease that afflicted Paul Klee, the famous artist. He died before the disease that killed him could be properly diagnosed. There was some conjecture afterwards that he may have suffered from scleroderma. The thorough and diligent research the author of this article has carried out over many years allows him to argue that Paul Klee was suffering from this autoimmune disease since 1935. With a degree of probability that borders on certainty, it seems that the artist suffered from ‘diffuse systemic sclerosis’, and it is from this, the most severe form of the rare autoimmune disease, that he died in 1940.

    The cyclin-dependent kinase inhibitor 3 (CDKN3) gene, involved in mitosis, is upregulated in cervical cancer (CC). We investigated CDKN3 mRNA as a survival biomarker and potential therapeutic target for CC. CDKN3 mRNA was measured in 134 CC and 25 controls by quantitative PCR. A 5-year survival study was conducted in 121 of these CC patients. Furthermore, CDKN3-specific siRNAs were used to investigate whether CDKN3 is involved in proliferation, migration, and invasion in CC-derived cell lines (SiHa, CaSki, HeLa). CDKN3 mRNA was on average 6.4-fold higher in tumors than in controls (p = 8 x 10−6, Mann-Whitney). A total of 68.2% of CC patients over expressing CDKN3 gene (fold change ≥ 17) died within two years of diagnosis, independent of the clinical stage and HPV type (Hazard Ratio = 5.0, 95% CI: 2.5–10, p = 3.3 x 10−6, Cox proportional-hazards regression). In contrast, only 19.2% of the patients with lower CDKN3 expression died in the same period. In vitro inactivation of CDKN3 decreased cell proliferation on average 67%, although it had no effect on cell migration and invasion. CDKN3 mRNA may be a good survival biomarker and potential therapeutic target in CC. PMID:26372210

    To secure the functionality of activated macrophages in the innate immune response, efficient life span control is required. Recognition of bacterial lipopolysaccharides (LPS) by toll-like receptor 4 (TLR4) induces downstream signaling pathways, which merge to induce the expression of cytokine genes and anti-apoptotic genes. MicroRNAs (miRNAs) have emerged as important inflammatory response modulators, but information about their functional impact on apoptosis is scarce. To identify miRNAs differentially expressed in response to LPS, cDNA libraries from untreated and LPS-activated murine macrophages were analyzed by deep sequencing and regulated miRNA expression was verified by Northern blotting and qPCR. Employing TargetScan(TM) we identified CASPASE-3 (CASP-3) mRNA that encodes a key player in apoptosis as potential target of LPS-induced miR-155. LPS-dependent primary macrophage activation revealed TLR4-mediated enhancement of miR-155 expression and CASP-3 mRNA reduction. Endogenous CASP-3 and cleaved CASP-3 protein declined in LPS-activated macrophages. Accumulation of miR-155 and CASP-3 mRNA in miRNA-induced silencing complexes (miRISC) was demonstrated by ARGONAUTE 2 (AGO2) immunoprecipitation. Importantly, specific antagomir transfection effectively reduced mature miR-155 and resulted in significantly elevated CASP-3 mRNA levels in activated macrophages. In vitro translation assays demonstrated that the target site in the CASP-3 mRNA 3'UTR mediates miR-155-dependent Luciferase reporter mRNA destabilization. Strikingly, Annexin V staining of macrophages transfected with antagomir-155 and stimulated with LPS prior to staurosporine (SSP) treatment implied that LPS-induced miR-155 prevents apoptosis through CASP-3 mRNA down-regulation. In conclusion, we report that miR-155-mediated CASP-3 mRNA destabilization in LPS-activated RAW 264.7 macrophages suppresses apoptosis, as a prerequisite to maintain their crucial function in inflammation.

    The tropospheric delay is one of the main errors for earth observation and a variety of radio navigation technologies, and the UNB3m model can be used to calculate the zenith tropospheric delay (ZTD) without any real measured meteorological data, which taking the major changes in water vapor profiles with latitude into account, and it widely applied in Wide Area Augmentation System in America. However, there are few researches carried out on the assessment of ZTD from UNB3m model over Asia area. In this study, three years of the ZTD data observed from 56 IGS (International GNSS service) sites distributed in Asia area is used to assess the effectiveness and accuracy of ZTD calculated from UNB3m model. The results are: (1) relative to IGS observed ZTD, the bias and root mean square (RMS) for ZTD calculated from UNB3m model are -0.1 cm and 6.0 cm, respectively. Besides, the bias shows significant periodic characteristics in Asia area. (2) The bias and RMS present seasonal variations, which generally show larger values in summer months. (3) The precision of ZTD calculated from UNB3m model increases with increasing altitude or latitude, and also the bias and RMS show inconsistently in different Asia areas. At last, the best results can be achieved in inland area where presents the mean yearly RMS of 2.4 cm. These results provide a reference for the study of the tropospheric delay correction model and the applications of real-time GNSS navigation and positioning.

    3-M syndrome is an autosomal recessive primordial growth disorder characterized by small birth size and post-natal growth restriction associated with a spectrum of minor anomalies (including a triangular-shaped face, flat cheeks, full lips, short chest and prominent fleshy heels). Unlike many other primordial short stature syndromes, intelligence is normal and there is no other major system involvement, indicating that 3-M is predominantly a growth-related condition. From an endocrine perspective, serum GH levels are usually normal and IGF-I normal or low, while growth response to rhGH therapy is variable but typically poor. All these features suggest a degree of resistance in the GH-IGF axis. To date, mutations in three genes CUL7, OBSL1 and CCDC8 have been shown to cause 3-M. CUL7 acts an ubiquitin ligase and is known to interact with p53, cyclin D-1 and the growth factor signalling molecule IRS-1, the link with the latter may contribute to the GH-IGF resistance. OBSL1 is a putative cytoskeletal adaptor that interacts with and stabilizes CUL7. CCDC8 is the newest member of the pathway and interacts with OBSL1 and, like CUL7, associates with p53, acting as a co-factor in p53-medicated apoptosis. 3-M patients without a mutation have also been identified, indicating the involvement of additional genes in the pathway. Potentially damaging sequence variants in CUL7 and OBSL1 have been identified in idiopathic short stature (ISS), including those born small with failure of catch-up growth, signifying that the 3-M pathway could play a wider role in disordered growth.

    St. Louis is tucked in a bend of the Mississippi River, just south of the point at which the Illinois River joins the larger Mississippi, and where the Missouri River flows in from the west. Drainage patterns to the east, on the Illinois side, are highlighted with green vegetation. Meandering rivers in the verdant Ozark Plateau appear to the south and west.

    This true-color view from NASA's Multi-angle Imaging SpectroRadiometer (MISR) was taken with the instrument's downward looking (nadir) camera on October 15, 2005. The urban areas of greater St. Louis show up as grey-white, including nearby Kirkwood, Webster Groves, Clayton, University City, Ferguson, St. Ann, St. Charles, and East St. Louis. The region is home to nearly three million people.

    MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Science Mission Directorate, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, Md. JPL is a division of the California Institute of Technology.

  5. Relevance of the ligand exchange rate and mechanism of fac-[(CO)3M(H2O)3]+ (M = Mn, Tc, Re) complexes for new radiopharmaceuticals.

    The water exchange process on fac-[(CO)3Mn(H2O)3]+ and fac-[(CO)3Tc(H2O)3]+ was kinetically investigated by 17O NMR as a function of the acidity, temperature, and pressure. Up to pH 6.3 and 4.4, respectively, the exchange rate is not affected by the acidity, thus demonstrating that the contribution of the monohydroxo species fac-[(CO)3M(OH)(H2O)2] is not significant, which correlates well with a higher pKa for these complexes compared to the homologue fac-[(CO)3Re(H2O)3]+ complex. The water exchange rate K298ex/s(-1) (DeltaHex double dagger/kJ mol(-1); DeltaSex double dagger/J mol(-1) K(-1); DeltaV double dagger/cm3 mol-1) decreases down group 7 from Mn to Tc and Re: 23 (72.5; +24.4; +7.1) > 0.49 (78.3; +11.7; +3.8) > 5.4 x 10(-3) (90.3; +14.5; -). For the Mn complex only, an O exchange on the carbonyl ligand could be measured (K338co = 4.3 x 10(-6) s(-1)), which is several orders of magnitude slower than the water exchange. In the case of the Tc complex, the coupling between 17O (I = 5/2) and 99Tc (I = 9/2) nuclear spins has been observed (1J99Tc,17O = 80 +/- 5 Hz). The substitution of water in fac-[(CO)3M(H2O)3]+ by dimethyl sulfide (DMS) is slightly faster than that by CH3CN: 3 times faster for Mn, 1.5 times faster for Tc, and 1.2 times faster for Re. The pressure dependence behavior is different for Mn and Re. For Mn, the change in volume to reach the transition state is always clearly positive (water exchange, CH3CN, DMS), indicating an Id mechanism. In the case of Re, an Id/Ia changeover is assigned on the basis of reaction profiles with a strong volume maximum for pyrazine and a minimum for DMS as the entering ligand. PMID:17140248

    2016-01-01

    In experiments on confinement and heating of plasma in the Uragan-3M torsatron, the method of high-frequency breakdown of the working gas is used. In these experiments, in conditions of a relatively stable magnetic field, the rf power supplied to the setup chamber has a frequency close to the ion-cyclotron frequency. Such a method of gas breakdown is not always sufficiently reliable. In our experiments, preliminary ionization of the working gas by the run-away electron beam is used for stabilizing the breakdown. This work contains the results of experiments on enhancement of the runaway electron beam and on the interaction of the runaway electron beam in the Uragan-3M torsatron with the HF electromagnetic pump field. This enables us to formulate a number of recommendations for using spontaneously formed beams of accelerated particles for stimulating the rf breakdown. Our results confirm the possibility of gas breakdown by runaway electrons.

The specific objectives and accomplishments of the work under this program were; Scale-up the current Generation-1 UBT from 12” width, as made on 3M’s pilot line, to 1+meter width full-scale manufacturing, while maintaining baseline performance metrics (see table below); This objective was fully met; Validate service life of Generation-1 UBT for the 25+ year lifetime demanded by the photovoltaic market; Aggressive testing revealed potential failure modes in the Gen 1 UBT. Deficiencies were identified and corrective action taken in the Gen 2 UBT; Develop a Generation-2 UBT on the pilot line, targeting improved performance relative to baseline, including higher %T (percent transmission), lower water vapor transmission rate (WVTR) with targets based on what the technology needs for 25 year lifetime, proven lifetime of 25 years in solar module construction in the field, and lower cost; Testing of UBT Gen 2 under a wide range of conditions presented in this report failed to reveal any failure mode. Therefore UBT Gen 2 is known to be highly durable. 3M will continue to test towards statistically validating a 25 year lifetime under 3M funding; Transfer Generation-2 UBT from the pilot line to the full-scale manufacturing line within three years; and This objective was fully met.

    The LIULIN-3M instrument is a further development of the LIULIN dosimeter-radiometer, which has been used on the NffR space station in the 1988-1994 time period, The LIULIN-3M is designed for continuous monitoring of the radiation environment during the BION-12 satellite flight in 1999. A semiconductor detector with 1 mm thickness and 1 cm(exp 2) area is used in the instrument. Pulse high analysis technique is used for measurement of the energy losses in the detector. The final data sets from the instrument are the flux and the dose rate for the exposition time and 256 channels of LET spectra if a non-nal coincidence of the particles to the detector is considered. The LIULIN-3M instrument was calibrated by proton fluxes with different energies at the Indiana University Cyclotron Facility in June 1997 and was used for space radiation measurements during commercial aircraft flights. Obtained calibration and flight results are analyzed in the paper.

  19. Neurotrophin-3 mRNA a putative target of miR21 following status epilepticus

    Risbud, Rashmi M.; Lee, Carolyn; Porter, Brenda E.

    2014-01-01

    Status epilepticus induces a cascade of protein expression changes contributing to the subsequent development of epilepsy. By identifying the cascade of molecular changes that contribute to the development of epilepsy we hope to be able to design therapeutics for preventing epilepsy. MicroRNAs influence gene expression by altering mRNA stability and/or translation and have been implicated in the pathology of multiple diseases. MiR21 and its co-transcript miR21*, microRNAs produced from either the 5″ or 3′ ends of the same precursor RNA strand, are increased in the hippocampus following status epilepticus. We have identified a miR21 binding site, in the 3′ UTR of neurotrophin-3 that inhibits translation. Neurotrophin-3 mRNA levels decrease in the hippocampus following SE concurrent with the increase in miR21. MiR21 levels in cultured hippocampal neurons inversely correlate with neurotrophin-3 mRNA levels. Treatment of hippocampal neuronal cultures with excess K+Cl−, a depolarizing agent mimicking the episode of status epilepticus, also results in an increase in miR21 and a decrease in neurotrophin-3 mRNA. MiR21 is a candidate for regulating neurotrophin-3 signaling in the hippocampus following status epilepticus. PMID:22019057

  3. Accuracy Assessment Study of UNB3m Neutral Atmosphere Model for Global Tropospheric Delay Mitigation

    NASA Astrophysics Data System (ADS)

    Farah, Ashraf

    2015-12-01

    Tropospheric delay is the second major source of error after the ionospheric delay for satellite navigation systems. The transmitted signal could face a delay caused by the troposphere of over 2m at zenith and 20m at lower satellite elevation angles of 10 degrees and below. Positioning errors of 10m or greater can result from the inaccurate mitigation of the tropospheric delay. Many techniques are available for tropospheric delay mitigation consisting of surface meteorological models and global empirical models. Surface meteorological models need surface meteorological data to give high accuracy mitigation while the global empirical models need not. Several hybrid neutral atmosphere delay models have been developed by (University of New Brunswick, Canada) UNB researchers over the past decade or so. The most widely applicable current version is UNB3m, which uses the Saastamoinen zenith delays, Niell mapping functions, and a look-up table with annual mean and amplitude for temperature, pressure, and water vapour pressure varying with respect to latitude and height. This paper presents an assessment study of the behaviour of the UNB3m model compared with highly accurate IGS-tropospheric estimation for three different (latitude/height) IGS stations. The study was performed over four nonconsecutive weeks on different seasons over one year (October 2014 to July 2015). It can be concluded that using UNB3m model gives tropospheric delay correction accuracy of 0.050m in average for low latitude regions in all seasons. The model's accuracy is about 0.075m for medium latitude regions, while its highest accuracy is about 0.014m for high latitude regions.

  4. The holistic 3M modality of drug delivery nanosystems for cancer therapy

    NASA Astrophysics Data System (ADS)

    2013-01-01

    Cancer has become the leading cause of human death worldwide. There are many challenges in the treatment of cancer and the rapidly developing area of nanotechnology has shown great potential to open a new era in cancer therapy. This article, rather than being exhaustive, focuses on the striking progress in the drug delivery nanosystems (DDNS) for cancer therapy and selects typical examples to point out the emerging mode of action of DDNS from our perspective. Among the outstanding advances in DDNS for cancer therapy is the development of ``multicomponent delivery systems'', ``multifunctional nanocarriers'' and ``multistage delivery systems''. However, these represent only one aspect of DDNS research. In addition, nature is the best teacher and natural evolution pressure has meant that virions conform to the ``multitarget, multistage and multicomponent'' (3M) mode of action. Amazingly, traditional Chinese medicine (TCM), used for over 4000 years in China, also displays the same mode of action. Integrating the previous notable progress in nanoparticle technology, learned from the building mode of natural virions and the action concept of TCM, we propose an integrity-based 3M mode DDNS for cancer therapy: multitarget, multistage and multicomponent, which are not fragmented parts but an interconnected integrity. Based on the physiological multitarget and the pharmacokinetic multistage, multicomponent DDNS are rationally designed, where different components with individual specific functions act in a synergistic manner against each target at each disposition stage to maximize the targeted delivery effectiveness. In this article, we introduce each component of 3M DDNS in detail and describe some typical cases to realize the tumor-homing purposes.

    The aim of the study was to assess the use of 3M porous polymer extraction discs (3M Empore sorbent filters) for detection of chemical permeation of protective clothing. Analysis of some commonly used solvents on 3M Empore sorbent filters was performed for methanol, acetone, trichloroethylene (TriCE), and toluene by solvent desorption and gas chromatography. All solvents exhibited >98 percent adsorption on the filters at a spiking level of 1.8 microL for each solvent. Solvent recovery for the system was calculated for each solvent, ranging from 72-94 percent (RSD < or = 4.0%) for all solvents over the spiking range 0.2-1.8 microL. The modified ASTM F739 method was used to determine breakthrough times for five protective glove materials (polyvinyl chloride, natural rubber, polymerized alkene, nitrile, and nitrile butyl rubber) using the model solvents as test chemicals. Breakthrough times for each type of protective glove were determined, and found to range from 36 s to 9 min for acetone, from 142 s to 52 min for methanol, from 18 s to 12 min for TriCE, and from 32 s to 28 min for toluene. The quantitative mass of the solvents on the filters at the time of breakthrough detection ranged from 150-159, 157-166, 570-581, and 371-382 microg/cm2 for acetone, methanol, TriCE, and toluene, respectively. The sorbent filter should find utility in collecting chemical permeation samples through protective gloves in both laboratory and field studies for quantitative analysis. PMID:11458919

    We have developed a parallel Particle-Particle, Particle-Mesh (P3M) simulation code for the Cray T3E parallel supercomputer that is well suited to studying the time evolution of systems of particles interacting via gravity and gas forces in cosmological contexts. The parallel code is based upon the public-domain serial Adaptive P3M-SPH (http://coho.astro.uwo.ca/pub/hydra/hydra.html) code of Couchman et al. (1995)[ApJ, 452, 797]. The algorithm resolves gravitational forces into a long-range component computed by discretizing the mass distribution and solving Poisson's equation on a grid using an FFT convolution method, and a short-range component computed by direct force summation for sufficiently close particle pairs. The code consists primarily of a particle-particle computation parallelized by domain decomposition over blocks of neighbour-cells, a more regular mesh calculation distributed in planes along one dimension, and several transformations between the two distributions. The load balancing of the P3M code is static, since this greatly aids the ongoing implementation of parallel adaptive refinements of the particle and mesh systems. Great care was taken throughout to make optimal use of the available memory, so that a version of the current implementation has been used to simulate systems of up to 109 particles with a 10243 mesh for the long-range force computation. These are the largest Cosmological N-body simulations of which we are aware. We discuss these memory optimizations as well as those motivated by computational performance. Performance results are very encouraging, and, even without refinements, the code has been used effectively for simulations in which the particle distribution becomes highly clustered as well as for other non-uniform systems of astrophysical interest.

    The treating of liquefied petroleum gas (LPG) to remove carbon dioxide and hydrogen sulfide using aqueous alkanolamine solutions is an important aspect of gas processing. One of the amines used in the natural gas industry is methyldiethanolamine (MDEA). Measurements of the phase equilibria in the carbon dioxide-propane-3 M MDEA system have been made at 25 and 40 C at pressures up to 15.5 MPa. Vapor-liquid, liquid-liquid, and vapor-liquid-liquid equilibria were determined. The vapor-liquid equilibrium data were compared with the model of Deshmukh and Mather.

    MCl2-, M(NO3)2-, and (Cl-M-NO3)- (M = Li, Na, K) species are systematically investigated using the density functional theory. In all the cases studied, the vertical detachment energies (VDEs) exceed the electron affinity of chlorine atom, leading to the conclusion that MCl2-, M(NO3)2- and (Cl-M-NO3)- are superhalogens. The VDEs of (Cl-M-NO3)- are between that of MCl2- and M(NO3)2-, showing that replacing one ligand with a larger electronegative ligand leads to the higher VDE. Superhalogens with suitable VDEs can be built by using different ligands.

    3M has had a silicon carbide, SiC, matrix/oxide fiber, ceramic composite, candle filter in test and on the market for several years. Because of the effects of some corrosive environments, 3M is developing an oxide matrix/oxide fiber hot gas candle filter which will be better suited for some of the environments which can degrade SiC. This paper will discuss the progress of the development of the oxide/oxide candle filter. Composite panels using three different Nextel{trademark} fibers but the same matrix material have been exposed to different simulated environmental conditions in the laboratory. Data will be presented on the effects of these environments on the composite panels. Also prototype candles have been made from the oxide/oxide system and data will be presented on the filtration characteristics, construction, and laboratory environmental exposures of these filters. Finally, if available, data will be presented on 12-in candle filters which have been exposed in an industrial test facility.

The gross national product is $83 million and the annual growth rate is 4.6%. There are no natural resources, and agricultural products include sugarcane, cotton, peanuts, and vegetables. Industry is made up of manufacturing 12.9%, transport and communications 13%, construction 9.1% and hotels and restaurants 4.5%. The Federation of St. Kitts and Nevis became independent in 1983. The government diversified the agriculture by planting other crops than sugar, producing gelled ethanol, and developing a cane spirits liquor. Tourism has grown the most and in 1987 passed sugar as the main source of income. International aid will assist in finishing a road that will open the southeast area of St. Kitts for construction of hotels, where some of the best beaches are located. PMID:12178070

    2016-06-01

    In this commentary on Paul Denis's paper 'The drive revisited: mastery and satisfaction', the author defends the idea of a plurality of metapsychologies that must be contrasted with and distinguished from each other while avoiding incompatible translations between models. In this connection he presents various theoretical approaches to aggression and the death drive, and demonstrates the differences between the drive model and the model underlying the theory of internalized object relations. The author holds that the concept of the internal object differs from Freud's notion of the representation (Vorstellung). He also considers that the imago as defined by Paul Denis in fact corresponds to the concept of the internal object. Lastly, he addresses the complex issue of listening to archaic forms of psychic functioning and their non-discursive presentation within the analytic process, which affects the transference-countertransference link.

    2011-01-01

    Attempts at improving the quality of mass spectra obtained from a Paul trap mass spectrometer prompted an investigation of the effects of additional fields to supplement the primary rf quadrupole trapping field. Reported here are the results of the first in a series of tests that focuses on the application of a single dipole field to augment the trapping and subsequent ejections of ions stored within a Paul trap. Measurements are presented for a fixed quadrupole frequency with varying dipole frequencies. The presence of the dipole field during the quadrupole trapping phase causes ion ejections of single m/z species at discrete dipole frequencies. During the mass analysis phase, the varying dipole frequency produces a complex set of resonant structures that impact ejection time (mass range), as well as mass spectral peak intensity and width

    2006-05-01

    Traditional geometries for ion traps involve three dimensional structures which may be difficult to assemble in complex geometries demanded by applications such as large-scale quantum computation. Planar Paul traps provide an alternative approach [Chiaverini et. al., Quant. Inf. Comput. 5, 419 (2005)], in which the RF and DC electrodes are placed in a single plane, providing simpler fabrication and greater optical access to the trapped ions. We have designed and constructed a planar Paul trap using copper electrodes on a Rogers 4350 substrate. Strontium ions were loaded into this structure at UHV, and also at high vacuum using helium buffer gas cooling. The temperature of the ion cloud as a function of buffer gas pressure is compared to predictions from a model which includes ion-helium collisions and RF heating. The measured trap parameters, including secular frequencies, trap depth, and RF heating rates, agree well with a pseudopotential model based on finite-element electrostatic calculations.

    In this paper, we present and discuss stability diagrams for Paul traps driven by two ac voltages. In contrast to a typical Paul trap, here we suggest a secondary ac voltage whose frequency is twice the frequency of the primary one. The ratio between their amplitudes can be used to expand the region of stability and to access different states of motion of trapped ions. This provides a further mechanism to trap, cool, and manipulate single ions and also to improve the experimental framework where ion clouds and crystals can be prepared and controlled. Such approach opens the possibility of designing more sophisticated trapping architectures, leading to a wide variety of applications on ion trap research and mass analysis techniques. PMID:26881458

    This report evaluated the feasibility of installing a cogeneration system at the Paul Masson Vineyards Winery in Saratoga, California. The feasibility study explores the technical and economic features of a variety of cogeneration systems. The system recommended is a 290 kilowatt natural gas fired rich burning Otto cycle internal combustion engine-generator set. Waste heat recovery would produce an average of 1500 gallons per hour of 180F. process water and provide for a peak of 4500 gallons per hour for four hours per day. The system would produce 1,670,000 kilowatt-hours of electric energy per year, have a capital cost of $191,000, and have a payback period of 2.3 years. The project would save over 18 billion BTU's per year compared to separate generation of steam by Paul Masson and electricity by the utility. Atmospheric emissions can be sufficiently controlled by using a non-selective reduction catalytic converter.

    The compact non-neutral plasma trap systems named "S-POD" have been developed at Hiroshima University as an experimental simulator of beam dynamics. S-POD is based either on a linear Paul trap or on a Penning trap and can approximately reproduce the collective motion of a relativistic charged-particle beam observed in the center-of-mass frame. We here employ the Paul trap system to investigate the behavior of an ion plasma near a dipole resonance. A simple method is proposed to calibrate the data of secular frequency measurements by using the dipole instability condition. We also show that the transverse density profile of an ion plasma in the trap can be estimated from the time evolution of ion losses caused by the resonance.

    In March 1988, there was an outbreak of infection by a strain of Salmonella saint-paul with a distinctive antigenic marker. A total of 143 reports were received between 1 March and 7 June. Preliminary investigations suggested that raw beansprouts were a possible source of infection and a case-control study confirmed the association. S. saint-paul of the epidemic type was isolated from samples of beansprouts on retail sale in different cities in the United Kingdom and from mung bean seeds on the premises of the producer who was most strongly associated with cases. In addition, Salmonella virchow PT34 was isolated from samples of raw beansprouts and was subsequently associated with seven cases of infection. Four other serotypes of salmonella were also isolated from beansprouts. On 8 April the public were advised to boil beansprouts for 15 seconds before consumption, and the premises of the one producer associated with many cases were closed. As a result of these actions there was a significant decrease in the number of infections with S. saint-paul. PMID:2323356

    In this article, the purpose is less praising Paul Ricoeur's work than enlightening how the reader may actually find some practical, even operative help in this philosophical thought. This is particularly true regarding the fields of medicine and care. Paul Ricœur is now worldwide renowned as a major philosophical figure of the 20th century, and with books such as "Oneself as another", he occupies a very peculiar place at the crossroads of phenomenology and hermeneutics. Through both these philosophical traditions, Paul Ricœur offers some narrative ethics which may greatly sustain caregivers in their reflexion. Yet, the aim of this article is to focus on this philosopher who invites us to inhabit and play a role in this world. The goal is also to bring out the pragmatic ethics that this thinker developed, based on Aristotelian and Kantian traditions. Then, this piece seeks to demonstrate how the three stages of Ricoeur's "petite éthique" (his "small ethics"), which are the self's aim "for the good life with and for others in just institutions" can shed some light on the ethical consideration of politicals and caregivers.

  15. Universal critical phenomena of the cloud --> crystal phase transition in the Paul trap: Powerlaws

    NASA Astrophysics Data System (ADS)

    Weiss, Daniel; Nam, Yunseong; Blümel, Reinhold

    N charged particles, simultaneously stored in a radio-frequency (rf) Paul trap, exhibit deterministic heating. Depending on the damping (γ) imparted to the system, these particles can exist in multiple phases, the most commonly found being the cloud and crystal phases. With a small γ, the particles exhibit gas-like behavior, where the heating and cooling equilibrate and a stable cloud results. For larger γ, the damping overcomes the heating and the particles are forced into the crystalline state. We explore the cloud --> crystal transition as a critical phenomenon. We find that the transition occurs at a critical value γc of the damping constant γ. We find that as a function of N, γc scales approximately like an iterated log law. We also present a universal power law, τm ~(γ -γc) - β , γ >γc , β > 0 , independent of both N and the Paul trap parameter a, depending only on the Paul trap parameter q, that describes the number of cycles necessary for the system to crystallize as a function of γ -γc .

    2016-05-01

    A common technique to measure ion-atom collision rates in a hybrid trap if the ions have no optical transitions (e.g. alkalis) is to monitor the fluorescence of the neutrals in the presence of a saturated linear Paul trap (LPT). We present numerical simulations, analytical calculations, and experimental results that show that the steady-state ion capacity of an LPT, Ns, exhibits nonlinear, nonmonotonic behavior as a function of ion loading rate, Λ. The steady state as a function of loading rate, Ns(Λ) , shows four distinct regions. In Region I, at the lowest Λ, Ns(Λ) increases monotonically. Then, Ns(Λ) reaches a plateau in Region II, before decreasing to a local minimum in Region III. Finally, in Region IV, Ns(Λ) once again increases monotonically. This behavior appears universal to any Paul trap, regardless of geometry or species trapped. We examine this behavior experimentally as a function of the q stability parameter of the Paul trap and simulate numerically the effect of the particular trap geometry on the onset of each of the four regions.

  17. Test of P3M-1 nacelle in Full-Scale Tunnel (FST)

    1931-01-01

    Test of P3M-1 nacelle in Full-Scale Tunnel (FST). The NACA conducted drag tests on P3M-1 nacelle in 1931 which were presented in a special report to the Navy. Smith DeFrance described this work in the report's introduction: 'Tests were conducted in the full-scale wind tunnel on a five to four geared Pratt and Whitney Wasp engine mounted in a P3M-1 nacelle. In order to simulate the flight conditions the nacelle was assembled on a 15-foot span of wing from the same airplane. The purpose of the tests was to improve the cooling of the engine and to reduce the drag of the nacelle combination. Thermocouples were installed at various points on the cylinders and temperature readings were obtained from these by the power plants division. These results will be reported in a memorandum by that division. The drag results, which are covered by this memorandum, were obtained with the original nacelle condition as received from the Navy with the tail of the nacelle modified, with the nose section of the nacelle modified, with a Curtiss anti-drag ring attached to the engine, with a Type G ring developed by the N.A.C.A., and with a Type D cowling which was also developed by the N.A.C.A.' (p. 1) This picture shows the engine with a Curtiss anti-drag ring attached. The NACA tested several different modifications and cowlings as noted above. The Navy did not want to make any major structural alterations to the original wing and nacelle installation. Thus, the NACA did not conduct a full investigation of the aerodynamics of this particular configuration. DeFrance concludes his report with this note: 'in view of the limitations of the test, the drag data for the combinations tested may be summarized, and considering the necessity of temperature control and accessibility to the engine it is apparent that the best combination tested was with the large nose piece, the Curtiss anti-drag ring, and the modified tail section.'

    Recently both Pressure- and Temperature-Sensitive Paint experiments were conducted at cryogenic conditions in the 0.3-m Transonic Cryogenic Tunnel at NASA Langley Research Center. This represented a re-introduction of the techniques to the facility after more than a decade, and provided a means to upgrade the measurements using newer technology as well as demonstrate that the techniques were still viable in the facility. Temperature-Sensitive Paint was employed on a laminar airfoil for transition detection and Pressure-Sensitive Paint was employed on a supercritical airfoil. This report will detail the techniques and their unique challenges that need to be overcome in cryogenic environments. In addition, several optimization strategies will also be discussed.

    The design for robotic telescopes to observe Gamma-Ray Burst (GRB) afterglows and the results of observations are presented. Quickly fading bright GRB flashes and afterglows provide a good tool to study an extremely early universe. However, most large ground-based telescopes cannot afford to follow-up the afterglows and flashes quickly within a few hours since a GRB explosion. We re-modeled the existing middle-class 1.3 m ø telescope of the near infrared band at ISAS in Japan to match for the above requirement. We also set a small telescope of 30 cm diameter with a conventional CCD. These telescopes can monitor afterglows quickly within a few minutes in J, H, Ks and R band with a grism spectrometer.

    Simultaneous advances in making, measuring, and modeling noble metal (plasmonic) particles--designated as the 3M's principle--have led to a perfect storm in discoveries and applications of gold nanoparticles. Three articles in this issue of ACS Nano illustrate this concept. First, exquisite control over gold nanorod length and diameter and testing of fundamental ideas are presented. Second, gold nanorods as localized surface plasmon resonance sensors to monitor the kinetics of antibody-antigen binding are reported. Third, strategies to prepare gold nanoshell substrates to enhance Raman scattering and infrared absorption are proposed. In this Perspective, we discuss how these reports fit into current challenges in plasmonics and how the prospects of localized surface plasmons will continue to shine when the right applications are revealed.

    2001-01-01

    Implementation of Stratospheric Aerosol Gas Experiment (SAGE) is a joint science mission between the Rosavioskosmos, also called Russian Aviation and Space Agency (RASA) and the National Aeronautics and Space Administration (NASA). Under the global collaboration agreement established by President Clinton and Yeltsin in 1995 between the United States and Russia, space was one of the major areas identified for joint scientific collaboration. There were several collaborative projects identified under space, earth, human exploration of space and aeronautics. SAGE was one of the key Earth Science instruments selected common to both countries' interests in ozone research. SAGE has a long space heritage, and four earlier versions of this instrument have flown in space for the last 15-year period. It has provided a vital ozone and aerosol data in the mid latitudes and has contributed in the overall ozone depletion research. SAGE II, the fourth instrument has been flying in space on NASA's Earth Radiation Budget Satellite (ERBS) for the last 14 years. Ball Aerospace built the instrument under Langley Research Center's (LaRC) management. SAGE III for Russian Meteor-3M mission is a third generation design with more spectral bands, elaborate data gathering and storage and intelligent terrestrial software. The Russian collaboration required a complete integration of SAGE III on the Russian Meteor-3M satellite and a launch on a Zenit-2 launch vehicle manufactured in Ukraine. The whole complex is scheduled to be launched from Baikonur cosmodrome in early 2001. This cooperative mission has presented a number of management, technical and logistical challenges on both sides. This paper makes an attempt to review and document such experiences.

  2. Modeling the hydrothermal circulation and the hydrogen production at the Rainbow site with Cast3M

    2012-12-01

    On the Mid-Atlantic Ridge, the Rainbow venting site is described as an ultramafic-hosted active hydrothermal site and releases high fluxes of methane and hydrogen [1, 2]. This behavior has first been interpreted as the result of serpentinization processes. But geochemical reactions involving olivine and plagioclase assemblages, and leading to chlorite, tremolite, talc and magnetite assemblages, could contribute to the observed characteristics of the exiting fluid [2]. The predominance of one of these geochemical reactions or their coexistence strongly depend on the hydrothermal fluid circulation. We developed and validated a 2D/3D numerical model using a Finite Volume method to simulate heat driven fluid flows in the framework of the Cast3M code [3, 4]. We also developed a numerical model for hydrogen production and transport that is based on experimental studies of the serpentinization processes [5-6]. This geochemical model takes into account the exothermic and water-consuming behavior of the serpentinization reaction and it can be coupled to our thermo-hydrogeological model. Our simulations provide temperatures, mass fluxes and venting surface areas very close to those estimated in-situ [7]. We showed that a single-path model [8] was necessary to simulate high values such as the in-situ measured temperatures and estimated water mass fluxes of the Rainbow site [7]. This single-path model will be used to model the production and transport of hydrogen at the Rainbow hydrothermal site. References [1]Charlou et al. (2010) AGU Monograph series. [2]Seyfried et al.

    In 1999, the National Optical Astronomy Observatories (NOAO) announced the opportunity to "assume responsibility for operation of the Kitt Peak 1.3-m telescope." A group of astronomers/educators from institutions across the USA successfully proposed to refurbish and automate the observatory and operate it as the Robotically Controlled Telescope (RCT). The RCT Consortium has been established between Francis Marion University, the Planetary Science Institute, South Carolina State University, Villanova University, and Western Kentucky University to oversee the refurbishment and automation, and operate the telescope to successfully achieve its research and education goals. The RCT was commissioned in 1964 as the Remotely Controlled Telescope and utilized that epoch's computing and communication technology to provide unattended operation from NOAO headquarters in Tucson, about 90 km distant. The original incarnation of the RCT allowed astronomers to gain experience in the remote operation of observatories in order to both develop techniques for operating space-based telescopes and to increase the productivity of ground-based telescopes (Maran 1967 Science 158, 867). While these tests worked as well as could be expected given the technology of the time, the telescope and observatory were refitted in 1969 for classical, attended operations. The second life of the 1.3-m was as a heavily subscribed KPNO visitor facility, first with photoelectric photometers and later as an important testbed for the newest infrared instrumentation. In 1996 the telescope was removed from the list of available KPNO facilities and stood idle until the RCT Consortium hired EOS Technologies, Inc. to refurbish and automate the observatory. In winter 2003 most of the observatory systems have been refurbished and the commissioning has begun. Refurbishment of the RCT has been made possible by NASA grant NAG58762.

    Digital flood-inundation maps for a 6.3-mile reach of the Mississippi River in Saint Paul, Minnesota, were developed through a multi-agency effort by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers and in collaboration with the National Weather Service. The inundation maps, which can be accessed through the U.S. Geological Survey Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/ and the National Weather Service Advanced Hydrologic Prediction Service site at http://water.weather.gov/ahps/inundation.php, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the U.S. Geological Survey streamgage at the Mississippi River at Saint Paul (05331000). The National Weather Service forecasted peak-stage information at the streamgage may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation. In this study, flood profiles were computed for the Mississippi River by means of a one-dimensional step-backwater model. The hydraulic model was calibrated using the most recent stage-discharge relation at the Robert Street location (rating curve number 38.0) of the Mississippi River at Saint Paul (streamgage 05331000), as well as an approximate water-surface elevation-discharge relation at the Mississippi River at South Saint Paul (U.S. Army Corps of Engineers streamgage SSPM5). The model also was verified against observed high-water marks from the recent 2011 flood event and the water-surface profile from existing flood insurance studies. The hydraulic model was then used to determine 25 water-surface profiles for flood stages at 1-foot intervals ranging from approximately bankfull stage to greater than the highest recorded stage at streamgage 05331000. The simulated water-surface profiles were then combined with a geographic information system digital elevation model, derived from high-resolution topography

  5. Mount St. Helens Rebirth

    2002-01-01

    The catastrophic eruption of Mt. St. Helens 20 years ago today (on May 18, 1980), ranks among the most important natural events of the twentieth century in the United States. Because Mt. St. Helens is in a remote area of the Cascades Mountains, only a few people were killed by the eruption, but property damage and destruction totaled in the billions of dollars. Mount St. Helens is an example of a composite or stratovolcano. These are explosive volcanoes that are generally steep-sided, symmetrical cones built up by the accumulation of debris from previous eruptions and consist of alternating layers of lava flows, volcanic ash and cinder. Some of the most photographed mountains in the world are stratovolcanoes, including Mount Fuji in Japan, Mount Cotopaxi in Ecuador, Mount Hood in Oregon, and Mount Rainier in Washington. The recently erupting Mount Usu on the island of Hokkaido in Japan is also a stratovolcano. Stratovolcanoes are characterized by having plumbing systems that move magma from a chamber deep within the Earth's crust to vents at the surface. The height of Mt. St. Helens was reduced from about 2950 m (9677 ft) to about 2550 m (8364 ft) as a result of the explosive eruption on the morning of May 18. The eruption sent a column of dust and ash upwards more than 25 km into the atmosphere, and shock waves from the blast knocked down almost every tree within 10 km of the central crater. Massive avalanches and mudflows, generated by the near-instantaneous melting of deep snowpacks on the flanks of the mountain, devastated an area more than 20 km to the north and east of the former summit, and rivers choked with all sorts of debris were flooded more than 100 km away. The area of almost total destruction was about 600 sq. km. Ash from the eruption cloud was rapidly blown to the northeast and east producing lightning which started many small forest fires. An erie darkness caused by the cloud enveloped the landscape more than 200 km from the blast area, and ash

    This Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image of Mt. St. Helens volcano in Washington State was acquired on August 8, 2000 and covers an area of 37 by 51 km. Mount Saint Helens, a volcano in the Cascade Range of southwestern Washington that had been dormant since 1857, began to show signs of renewed activity in early 1980. On 18 May 1980, it erupted with such violence that the top of the mountain was blown off, spewing a cloud of ash and gases that rose to an altitude of 19 kilometers. The blast killed about 60 people and destroyed all life in an area of some 180 square kilometers (some 70 square miles), while a much larger area was covered with ash and debris. It continues to spit forth ash and steam intermittently. As a result of the eruption, the mountain's elevation decreased from 2,950 meters to 2,549 meters. The simulated fly-over was produced by draping ASTER visible and near infrared image data over a digital topography model, created from ASTER's 3-D stereo bands. The color was computer enhanced to create a 'natural' color image, where the vegetation appears green. The topography has been exaggerated 2 times to enhance the appearance of the relief. Landsat7 aquired an image of Mt. St. Helens on August 22, 1999. Image and animation courtesy NASA/GSFC/MITI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team.

    The 1.3 m (50 inch) telescope on Kitt Peak has been refurbished and provided with an autonomous scheduler. It is operated by The Robotically Controlled Telescope (RCT) consortium whose members are: South Carolina State, Villanova and Western Kentucky Universities. The facility possesses 5 board (UBVRI) and 11 narrow-band filters. Attached to the RCT camera is a 2048 x 2048 SITe SI-424A back-illuminated CCD with 24 micrometer pixels. We used over 7,000 star measurements from 37, 198s R-images to compute the astrometric and photometric accuracy. The difference of the J2000 coordinates computed from the RCT images and the J2000 Nomad catalog coordinate values in right ascension peaks at 0.058”, while the declination peaks at -0.125”. We obtained these astrometric results using the simplest assumptions: linear relationship between standard coordinates and measured coordinates, no color or magnitude dependency and no differential refraction (all images taken in the zenith). We express the photometric accuracy in the following manner: The Signal-to-Noise-Ratio as a function of apparent magnitude shows that the RCT is not noise dominated at m < 20 magnitude.

    A straightforward and reproducible synthesis of crack-free large-area thin films of 3D hexagonal (R-3m) mesostructured nanocrystalline titania (meso-nc-TiO{sub 2}) using a Pluronic triblock copolymer (P123)/1-butanol templating system is described. The characterization of the films is achieved using a combination of electron microscopy (high-resolution scanning electron microscopy and scanning transmission electron microscopy), grazing-incidence small-angle X-ray scattering, in situ high-temperature X-ray diffraction, and variable-angle spectroscopic ellipsometry. The mesostructure of the obtained films is found to be based upon a 3D periodic array of large elliptically shaped cages with diameters around 20 nm interconnected by windows of about 5 nm in size. The mesopores of the film calcined at 300 C are very highly ordered, and the titania framework of the film has a crystallinity of 40 % being composed of 5.8 nm sized anatase crystallites. The film displays high thermal stability in that the collapse of the pore architecture is incomplete even at 600 C. The accessible surface area of 3D hexagonal meso-nc-TiO{sub 2} estimated by the absorption of methylene blue is nearly twice as large as that of 2D hexagonal meso-nc-TiO{sub 2} at the same annealing temperature.

    Recent in vivo human leg MREIT experiments showed successful conductivity image reconstructions using carbon-hydrogel electrodes and optimized RF coils. However, it is still difficult to perform in vivo human and disease model animal experiments primarily due to a long scan time and high injection current of about 9 mA. Compared to previous MREIT pulse sequences, a newly developed multi-echo pulse sequence provides a higher SNR of MR magnitude image and better quality of magnetic flux density data. Unlike the human calf, the knee has sensitive nerve bundles and mainly consists of the bone. In this study, we tried to obtain high-resolution conductivity images of in vivo human knees using the multi-echo pulse sequence. We injected as much as 3 mA current in the form of an 81 ms pulse into the knee without producing a painful sensation and motion artifacts. Reconstructed conductivity images well distinguish different parts of the subcutaneous adipose tissue, muscle, synovial capsule, cartilage and bone inside the knee. Considering clinical applications, future work should be focused on in vivo human and disease model animal experiments.

    The practice of detecting and enumerating all oxidase-negative, glucose-fermenting-Gram-negative rods (i.e., the family Enterobacteriaceae) is used to indicate unsanitary or inadequate food processing conditions. The objective of this interlaboratory collaborative study was to evaluate and compare the methods described in Standard Methods for the Examination of Dairy Products (SMEDP) and the Compendium of Methods for the Microbiological Examination of Foods (Compendium) with a commercial product, the 3M Petrifilm Enterobacteriaceae Count Plate, for the recovery of Enterobacteriaceae in foods. Six foods--cheddar cheese, milk, flour, frozen prepared meals, frozen broccoli, and nut pieces--were analyzed for Enterobacteriaceae by 12 collaborating laboratories. For each food tested, the collaborators received 8 blind test portions consisting of a control test portion and 3 levels of inoculated test portion, each in duplicate. Each test portion was tested by the Petrifilm Enterobacteriaceae Count Plate method as well as the SMEDP or Compendium methods. The precision estimates (repeatability or within-laboratory variation, and reproducibility or between-laboratory variation) were calculated with standard statistical techniques. PMID:14509441

    Motivated by the potential high temperature superconductivity in hydrogen-rich materials, high-pressure structures of ErH3 and HoH3 were studied by using genetic algorithm method. Our calculations indicate that both ErH3 and HoH3 transform from P-3c1 structure to a monoclinic C2/m structure at about 15 GPa, and then transforms into a cubic Fm-3m structure at about 40 GPa. ErH3 and HoH3 adopt the same P63/mmc structure with space group P63/mmc at above about 220 and 196 GPa, respectively. For ErH3, the P63/mmc phase is stable up to at least 300 GPa, while for HoH3, a phase transformation P63/mmc → Cmcm occurs at about 216 GPa, and the Cmcm phase is stable up to at least 300 GPa. The P-3c1 ErH3 and HoH3 are calculated to demonstrate non-metallic character, and the other phases are all metallic phases.

    The reactions of deuterated methanol, ethanol, 1-propanol, 1-butanol, 2-propanol, 2-butanol and t-butanol over cyclic (MO3)3 (M = Mo, W) clusters were studied experimentally with temperature programmed desorption (TPD) and theoretically with coupled cluster CCSD(T) theory and density functional theory. The reactions of two alcohols per M3O9 cluster are required to provide agreement with experiment for D2O release, dehydrogenation and dehydration. The reaction begins with the elimination of water by proton transfers and forms an intermediate dialkoxy species which can undergo further reaction. Dehydration proceeds by a β hydrogen transfer to a terminal M=O. Dehydrogenation takes place via an α hydrogen transfer to an adjacent MoVI = O atom or a WVI metal center with redox involved for M = Mo and no redox for M = W. The two channels have comparable activation energies. H/D exchange to produce alcohols can take place after olefin is released or via the dialkoxy species depending on the alcohol and the cluster. The Lewis acidity of the metal center with WVI being larger than MoVI results in the increased reactivity of W3O9 over Mo3O9 for dehydrogenation and dehydration.

    The Robotically Controlled Telescope (RCT) 1.3 m telescope, formerly known as the Kitt Peak National Observatory (KPNO) 50 inch telescope, has been refurbished as a fully robotic telescope, with an autonomous scheduler to take full advantage of the observing site without the requirement of a human presence. Here we detail the current configuration of the RCT and present, as a demonstration of its high-priority science goals, the broadband UBVRI photometric calibration of the optical facility. In summary, we find the linear color transformation and extinction corrections to be consistent with similar optical KPNO facilities, to within a photometric precision of 10% (at 1σ). While there were identified instrumental errors that likely added to the overall uncertainty, associated with since-resolved issues in engineering and maintenance of the robotic facility, a preliminary verification of this calibration gave a good indication that the solution is robust, perhaps to a higher precision than this initial calibration implies. The RCT has been executing regular science operations since 2009 and is largely meeting the science requirements set during its acquisition and redesign.

    2008-03-01

    In order to investigate the mass distribution of Population III stars, we have developed high-resolution cosmological hydrodynamic simulations in a standard ΛCDM universe. We use a Particle-Particle-Particle-Mesh (P3M) scheme for gravity force calculations, where the PP part is calculated by GRAPE (special purpose board for gravity calculation). The baryon component is treated by Smoothed Particle Hydrodynamics (SPH) method. The simulations are performed on a newly developed dedicated PC-cluster system named FIRST simulator with the peak speed of 36 T flops at the University of Tsukuba. Using this simulator, we perform high-resolution simulations with 2×107 of dark matter and SPH particles, respectively. With this large number of particles, sub-solar mass resolution for baryon particles can be achieved all over the simulation box. Therefore, we can resolve small scale density fluctuations, which may play an important role in the formation of intermediate-mass Pop III stars formation.

  17. Characteristics of ICR-produced peripheral plasma in the Uragan-3M torsatron

    Besedin, N. T.; Chechkin, V. V.; Fomin, I. P.

    Some plasma parameters outside the confinement volume near the last closed magnetic surface (LCMS) and in the divertor fluxes were studied by probe and microwave techniques during ICR production and heating of the plasma in the Uragan-3M torsatron. When moving around the LCMS, the steepness of the radial density, electron temperature, and potential profiles increase with distance away from the 'rib' of the LCMS. The quasi-steady radial electric field E(sub r) near the LCMS exceeds 100 V/cm and is directed outwards, opposite to the calculated ambipolar electric field inside the confinement volume. It is shown that the total flow of the diverted plasma in the spacing between two helical windings consists of a weakly mobile non-resonant component which is presumably formed at the periphery due to ionization, and a component whose value and poloidal location are sensitive to resonance conditions for RF power absorption, this flow being apparently formed by a plasma diffusing through the LCMS and/or generated near the LCMS, where the filed E(sub r) is localized. Based on plasma parameters measurements after the RF pulse is switched off, a qualitative model of peripheral plasma dynamics after the end of the RF heating is constructed.

    This paper describes results from a seven-day demonstration of the use of 3M Empore(R) membrane filter loaded with ion exchange material (potassium cobalt hexacynoferrate) for cesium uptake from the R-Disassembly Basin at the Savannah River Site. The goal of the demonstration was to evaluate the ability of the Process Absorber Development unit, a water pre-filtration /CoHex configuration on a skid, to remove cesium from R-Disassembly Basin at a linear processing flow rate of 22.9 liters per minute (1,204 liters/minute/m2). Over 210,000 liters of R-Disassembly Basin water was processed through the PADU without a cesium breakthrough, that is, the effluent after treatment with CoHex, contained less than detectable amounts of radioactive cesium. Some of the observed advantages of the Empore(R) membrane filter technology over conventional packed column ion exchange systems include rapid flow rates without channeling effects, low volume secondary waste and fast extraction or rapid kinetics per unit of flow.

  19. Understanding the spin-driven polarizations in Bi MO3 (M = 3 d transition metals) multiferroics

    NASA Astrophysics Data System (ADS)

    Kc, Santosh; Lee, Jun Hee; Cooper, Valentino R.

    Bismuth ferrite (BiFeO3) , a promising multiferroic, stabilizes in a perovskite type rhombohedral crystal structure (space group R3c) at room temperature. Recently, it has been reported that in its ground state it possess a huge spin-driven polarization. To probe the underlying mechanism of this large spin-phonon response, we examine these couplings within other Bi based 3 d transition metal oxides Bi MO3 (M = Ti, V, Cr, Mn, Fe, Co, Ni) using density functional theory. Our results demonstrate that this large spin-driven polarization is a consequence of symmetry breaking due to competition between ferroelectric distortions and anti-ferrodistortive octahedral rotations. Furthermore, we find a strong dependence of these enhanced spin-driven polarizations on the crystal structure; with the rhombohedral phase having the largest spin-induced atomic distortions along [111]. These results give us significant insights into the magneto-electric coupling in these materials which is essential to the magnetic and electric field control of electric polarization and magnetization in multiferroic based devices.

    First observations of quasi-coherent fluctuations in the frequency range of 20-400 kHz in Alfvén-wave-heated plasmas of the U-3M torsatron are presented. The excitation conditions of these modes depend on the radio frequency antenna type and the plasma density, the appearance of the modes correlating with the presence of both suprathermal electrons and high-energy ions in the plasma, which supports our opinion that the modes are excited by energetic particles. Complicated evolution of the mode frequencies with abrupt changes at the instants of plasma confinement transitions is observed at the initial stage of each discharge. The frequencies become stable at the stage of the plasma current flattop. Raw estimates show that toroidicity-induced Alfvén eigenmodes could be responsible for the 150-400 kHz fluctuations. Low-frequency 20-70 kHz bursts are observed during plasma confinement transitions. The poloidal mode number of one of these bursts with the frequency of 20 kHz burst was determined to be m = 2. This mode rotated in the electron diamagnetic rotation direction with a frequency lower than the geodesic acoustic mode frequency and can be identified as a drift-sound-type mode.

  1. Paul's gospel and the rhetoric of apostolic rejection: A study of Galatians 1:15--17, 1 Corinthians 15:8, F. C. Baur, and the origins of Paul's Gentile mission

    Mitchell, Matthew Wesley

    This dissertation proposes a new understanding of Paul's Gentile mission and its relationship to his so-called "conversion." This dissertation examines the origins of Paul's mission to the Gentiles, and locates it in his claims to have been personally commissioned to undertake such a mission by Jesus. Specifically, I argue that it is the rejection of Paul's claim to be an apostle, a claim founded upon his "conversion" experience, that precipitates his mission to the Gentiles. In arguing this view, I draw upon Ferdinand Christian Baur's nineteenth century theories concerning both the unreliability of Acts as a historical source, and his proposal of a clear division between Paul and the other apostles. In establishing the methodological and theoretical framework of the dissertation, I discuss the "New Perspective on Paul" that has dominated New Testament scholarship over the past thirty years. My study is also informed methodologically by the growing interest in rhetorical criticism among biblical scholars, although the emphasis of this dissertation bears more of a resemblance to the approach of the New Rhetoric than the categories of classical, Greco-Roman rhetoric. The textual component of this work falls into two stages. The first contains a full examination of Paul's "conversion passages" in Galatians 1:15--17 and 1 Corinthians 15:8, attempting to situate these seemingly unusual self-descriptions in their cultural contexts. The second involves an examination of F. C. Baur's presentation of Paul, and the reception of Baur's views among biblical scholars throughout the years following his scholarly activity. This dissertation makes two claims, each of which can stand on its own as an important contribution to scholarship. My first claim is that components of Baur's work support my proposal concerning Paul's Gentile mission and his experience of apostolic rejection, and that this proposal has much to commend it as an explanation of a perennial scholarly puzzle.

    Last spring, The Healthcare Forum and 3M together announced the 21st Century Innovator Awards. They hoped to spotlight examples of the most forward-thinking organizations in American healthcare--organizations that could demonstrate readiness for the next century through the process of rebuilding their systems and structures. THF and 3M were looking for models for success with: (1) an organizational vision for the future, (2) an integrated planning process which reflected that vision, and (3) a measurable future benefit to the communities they served. The call elicited responses from more than 40 organizations across the country. THF and 3M were overwhelmed by both their range and quality. Choosing was difficult. But last September two winners were unveiled at the THF-3M Visionary Leadership conference in Hilton Head, South Carolina. Memorial Hospital and Health System of South Bend, Indiana, took the large, urban, regional, and national award for its progress in the long, tough process of revisioning itself according to a strategic concept CEO Phil Newbold calls "Quality Through People." The small, rural, and suburban prize went to Yavapai Regional Medical Center in Prescott, Arizona, where CEO Pat Linton is attempting to shape a "Total Healing Environment." We asked Joe Flower to visit both sites and send back an eyewitness report on what makes these two progressive organizations models for healthcare in the '90s and beyond. PMID:10117133

  3. Insights into the crystal chemistry of Earth materials rendered by electron density distributions: Pauling's rules revisited

    2014-05-20

    Pauling's first two rules are examined in terms of the accumulation of the electron density between bonded pairs of atoms for a relatively large number of oxide and silicate crystals and siloxane molecules. The distribution of the electron density shows that the radius of the oxygen atom is not fixed, but that it actually decreases systematically from ~1.40 Å to ~ 0.65 Å as the polarizing power and the electronegativity of the bonded metal atoms increase and the distribution of the O atom is progressively polarized and contracted along the bond vectors by the impact of the bonded interactions. The contractions result in an aspherical oxygen atom that displays as many different bonded “radii” as it has bonded interactions. The bonded radii for the metal atoms match the Shannon and Prewitt ionic radii for the more electropositive atoms like potassium and sodium, but they are systematically larger for the more electronegative atoms like aluminum, silicon and phosphorous. Pauling's first rule is based on the assumption that the radius of the oxide anion is fixed and that the radii of the cations are such that radius sum of the spherical oxide anion and a cation necessarily equals the separation between the cation-anion bonded pair with the coordination number of the cation being determined by the ratio of the radii of the cation and anion. In the case of the bonded radii, the sum of the bonded radii for the metal atoms and the oxide anion necessarily equals the bond lengths by virtue of the way that the bonded radii were determined in the partitioning of the electron density along the bond path into metal and O atom parts. But, the radius ratio for the O and M atoms is an unsatisfactory rule for determining the coordination number of the metal atom inasmuch as a bonded O atom is not, in general, spherical, and its size varies substantially along its bonded directions. But by counting the number of bond paths that radiate from a bonded atom, the coordination

    Magnesium aluminum spinel (MgAl 2O 4) is a major constituent of the shallow upper mantle. It is of great geophysical importance to explore its physical properties under high pressure and temperature. The first-principle density functional theory (DFT) with the plane wave along with pseudopotential was employed to obtain the total energy for both Fd3m-MgAl 2O 4 and F4-3m-MgAl 2O 4, which was used to generate the Gibbs free energy as a function of temperature and pressure with the quasi-harmonic Debye model. It is found that the phase transition temperature from Fd3m-MgAl 2O 4 to F4-3m-MgAl 2O 4 is beyond 452.6 K in the pressure regime studied, which is consistent with the experiment. The phase transition temperature is related to pressure by a linear function, i.e. T=8.05 P+452.6, which is the first equation of this kind to describe the phase transition Fd3m→F4-3m. The elastic constants, equation of states and thermodynamic properties of Fd3m-MgAl 2O 4 are also reported in this paper to make a complete study.

Make sure to look through the red lens with your left eye. Figure 1: This ASTER image of Mt. St. Helens volcano in Washington was acquired on August 8, 2000 and covers an area of 37 by 51 km. Mount Saint Helens, a volcano in the Cascade Range of southwestern Washington that had been dormant since 1857, began to show signs of renewed activity in early 1980. On 18 May 1980, it erupted with such violence that the top of the mountain was blown off, spewing a cloud of ash and gases that rose to an altitude of 19 kilometers. The blast killed about 60 people and destroyed all life in an area of some 180 square kilometers (some 70 square miles), while a much larger area was covered with ash and debris. It continues to spit forth ash and steam intermittently. As a result of the eruption, the mountain's elevation decreased from 2,950 meters to 2,549 meters. The image is centered at 46.2 degrees north latitude, 122.2 degrees west longitude.

    Movie: The simulated fly-over was produced by draping ASTER visible and near infrared image data over a digital topography model, created from ASTER's 3-D stereo bands. The color was computer enhanced to create a natural color image, where the vegetation appears green. The topography has been exaggerated 2 times to enhance the appearance of the relief.

    This article examines the life and work of Dr Paul Carton (1875-1947), a French physician who promoted 'naturist vegetarianism". His career and the evolution of his ideas were influenced by his own experience as a young man of treatment for tuberculosis, and by an anti-materialist philosophy. He developed a diet for his patients that became influential through his writings and through the activities of the French Naturist Society. Although by no means the only advocate of such ideas, Carton's influence has survived and can still be discerned in a close reading of the present-day French popular press. PMID:11695355

    Due to the worldwide shortage of organs for transplantation, there has been an increased use of organs obtained after circulatory death alone. A protocol for this procedure has recently been approved by a major transplant consortium. This development raises serious moral and ethical concerns. Two renowned theologians of the previous generation, Paul Ramsey and Moshe Feinstein, wrote extensively on the ethical issues relating to transplantation, and their work has much relevance to current moral dilemmas. Their writings relating to definition of death, organ transplantation and the care of the terminally ill are briefly presented, and their potential application to the moral problem of organ donation after circulatory death is discussed.

    The scheme for two-dimensional wall adaptation with sulfur hexafluoride (SF6) as test gas in the NASA Langley Research Center 0.3-m Transonic Cryogenic Tunnel (0.3-m TCT) is presented. A unified version of the wall adaptation software has been developed to function in a dual gas operation mode (nitrogen or SF6). The feature of ideal gas calculations for nitrogen operation is retained. For SF6 operation, real gas properties have been computed using the departure function technique. Installation of the software on the 0.3-m TCT ModComp-A computer and preliminary validation with nitrogen operation were found to be satisfactory. Further validation and improvements to the software will be undertaken when the 0.3-m TCT is ready for operation with SF6 gas.

SAGE III is a spectrometer that measures attenuated radiation in the 282 nm to 1550 nm wavelength range to obtain the vertical profiles of ozone, aerosols, and other chemical species that are critical in studying the trends for the global climate change phenomena. This instrument version is more advanced than any of the previous versions and has more spectral bands, elaborate data gathering and storage, and intelligent terrestrial software. There are a number of Russian scientific instruments aboard the Meteor satellite in addition to the SAGE III instrument. These instruments deal with land imaging and biomass changes, hydro-meteorological monitoring, and helio-geophysical research. This mission was under development for over a period of six years and offered a number of unique technical and program management challenges for both Agencies. SAGE III has a long space heritage, and four earlier versions of this instrument have flown in space for nearly two decades now. In fact, SAGE II, the fourth instrument, is still flying in space on NASA's Earth Radiation Budget Satellite (ERBS), and has been providing important atmospheric data over the last 18 years.

    Recent radial-velocity surveys for GK clump giants have revealed that planets also exist around {approx}1.5-3 M{sub sun} stars. However, no planets have been found inside 0.6 AU around clump giants, in contrast to solar-type main-sequence stars, many of which harbor short-period planets such as hot Jupiters. In this study, we examine the possibility that planets were engulfed by host stars evolving on the red-giant branch (RGB). We integrate the orbital evolution of planets in the RGB and helium-burning phases of host stars, including the effects of stellar tide and stellar mass loss. Then we derive the critical semimajor axis (or the survival limit) inside which planets are eventually engulfed by their host stars after tidal decay of their orbits. Specifically, we investigate the impact of stellar mass and other stellar parameters on the survival limit in more detail than previous studies. In addition, we make detailed comparisons with measured semimajor axes of planets detected so far, which no previous study has done. We find that the critical semimajor axis is quite sensitive to stellar mass in the range between 1.7 and 2.1 M{sub sun}, which suggests a need for careful comparison between theoretical and observational limits of the existence of planets. Our comparison demonstrates that all planets orbiting GK clump giants that have been detected are beyond the survival limit, which is consistent with the planet-engulfment hypothesis. However, on the high-mass side (>2.1M{sub sun}), the detected planets are orbiting significantly far from the survival limit, which suggests that engulfment by host stars may not be the main reason for the observed lack of short-period giant planets. To confirm our conclusion, the detection of more planets around clump giants, especially with masses {approx}> 2.5M{sub sun}, is required.

    Substrates for solar arrays intended to be used on satellite systems are generally made of aluminum honeycomb structure sandwiched with Carbon Fiber Reinforced Plastic (CFRP) face skin. Two mil thick KaptonTM sheets are co cured on one side of the aluminum /CFRP composite structure while realizing the substrate panels. This Kapton sheet would serve as an insulator over which solar cell blankets are bonded with suitable adhesive for the satellite solar panels. The satellite solar panels demands highest degree of quality and reliability and one of the prime factors in this regards is the bond strength of adhesive which is used to bond the solar cell blankets. Various methods of pretreatments of Kapton surface are in use for increasing the surface energy, which in turn results in improved bond strengths. These methods generally provide roughened surface of the Kapton which is achieved either by abrasive means like scrubbing the surface using fine silica chip, or plasma etching or alternatively by an additive process wherein suitable polyester, phenolic or other resins are coated on to the Kapton surface to achieve the desired results. For spacecraft solar panel applications at ISRO, polyester resin coating on to the Kapton surface was used as pretreatment prior to adhesive application. This process had provided adequate bond strengths between the solar cells and Kapton. Due to issues related to the supply of the polyester resin material from the vendor alternative methods of pretreatments were explored. In this paper, a novel process developed for Kapton pretreatment is described along with results of relevant qualifications for the satellite solar panel application. This newly developed pretreatment process for Kapton successfully adopts an epoxy based material 3M Scotch weld 2216 which is widely used in spacecraft electronic hardware.

    Detection of murmurs and gallops may help to identify cats with heart disease. However, auscultatory findings may be subject to clinically relevant observer variation. The objective of this study was to evaluate an electronic stethoscope (ES) in cats. We hypothesized that the ES would perform at least as well as a conventional stethoscope (CS) in the detection of abnormal heart sounds. One hundred and fifty consecutive cats undergoing echocardiography were enrolled prospectively. Cats were ausculted with a CS (WA Tycos Harvey Elite) by two observers, and heart sounds were recorded digitally using an ES (3M Littmann Stethoscope Model 3200) for off-line analysis. Echocardiography was used as the clinical standard method for validation of auscultatory findings. Additionally, digital recordings (DRs) were assessed by eight independent observers with various levels of expertise, and compared using interclass correlation and Cohen's weighted kappa analyses. Using the CS, a heart murmur (n = 88 cats) or gallop sound (n = 17) was identified in 105 cats, whereas 45 cats lacked abnormal heart sounds. There was good total agreement (83-90%) between the two observers using the CS. In contrast, there was only moderate agreement (P <0.001) between results from the CS and the DRs for murmurs, and poor agreement for gallops. The CS was more sensitive compared with the DRs with regard to murmurs and gallops. Agreement among the eight observers was good-to-excellent for murmur detection (81%). In conclusion, DRs made with the ES are less sensitive but comparably specific to a CS at detecting abnormal heart sounds in cats. PMID:23599254

    Just over a century ago Paul Ehrlich received the Nobel Prize for his studies of immunity. This review describes one of his legacies, the histochemical description of the mast cell, and the research that has ensued since then. After a long period of largely descriptive studies, which revealed little about the biological role of the mast cell, the field was galvanized in the 1950s by the recognition that the mast cell was the main repository of histamine and a key participant in anaphylactic reactions. Although the mast cell was long-viewed in these terms, recent research has now shown that the mast cell also plays a key role in innate and adaptive immune responses, autoimmune disease, and possibly tissue homeostasis by virtue of its expression of a diverse array of receptors and biologically active products. In addition, the responsiveness of mast cells to immunological and pathological stimulants is highly modulated by the tissue cytokine environment and by synergistic, or inhibitory, interactions among the various mast cell receptor systems. This once enigmatic cell of Paul Ehrlich has proved to be both adaptable and multifunctional. PMID:19130582

    Three meter field-aligned irregularities (3 m FAIs) associated with medium-scale traveling ionospheric disturbances (MSTIDs) that occurred on 5 February 2008 were observed by using the Chung-Li 52 MHz coherent scatter radar. Interferometry measurements show that the plasma structures responsible for the 3 m FAI echoes are in a clumpy shape with a horizontal dimension of about 10-78 km in a height range of 220-300 km. In order to investigate the dynamic behaviors of the plasma irregularities at different scales in the bottomside of F region, the VHF radar echo structures from the 3 m FAIs combined with the 630 nm airglow images provided by the Yonaguni all-sky imager are compared and analyzed. The results show that the radar echoes were located at the west edge of the depletion zones of the 630 nm airglow image of the MSTIDs. The bulk echo structures of the 3 m FAIs drifted eastward at a mean trace velocity of about 30 m/s that is in general agreement with the zonal trace velocity of the MSTIDs shown in the 630 nm airglow images. These results suggest that the observed F region 3 m FAIs for the present case can be regarded as the targets that are frozen in the local region of the MSTIDs. In addition, the radar-observed 3 m FAI echo intensity and spectral width bear high correlations to the percentage variations of the 630 nm emission intensity. These results seem to suggest that through the nonlinear turbulence cascade process, the MSTID-associated 3 m FAIs are very likely generated from the kilometer-scale plasma irregularities with large amplitude excited by the gradient drift instability.

    This paper highlights the utility of 2D and 3D ultrasonography in the prenatal diagnosis of facial dysmorphisms suggestive of very rare syndromes such as 3-M syndrome. Two pregnant women at risk for fetal skeletal dysplasias were referred to our clinic for 2D/3D ultrasound scan in the second trimester of pregnancy. Only one of the patients had a familial history of 3-M syndrome. Karyotyping and genetic testing of abortion material were performed in both cases. 2D ultrasonography revealed growth retardation of the long bones in both cases. In the case without a familial history of the syndrome, 2D and 3D ultrasonography showed an absence of nasal bones and a flat malar region suggestive of 3-M syndrome, although the difficult differential diagnosis included other dysmorphic growth disorders with prenatal onset. The karyotype was normal but the pregnancy was terminated in both cases. Postmortem examination confirmed 3-M syndrome as indicated by prenatal findings. In high-risk cases with a familial history of 3-M syndrome, prenatal diagnosis of 3-M syndrome is possible by analyzing fetal DNA. In the absence of risk, a definitive prenatal diagnosis is often not possible but may be suspected in the presence of shortened long bones, normal head size and typical flattened malar region (midface hypoplasia) shown on complementary 2D and 3D sonograms. 2D and 3D ultrasonography has been shown to offer reliable information for the prenatal study of skeletal and facial anomalies and can be useful if there is a suspicion of 3-M syndrome in a pregnancy not known to be at risk.

    The Schedule Organizer, SO (COSMIC Program MSC-21525), Schedule Tracker, ST, and Schedule Report Generator, SRG (COSMIC Program MSC-21527), are programs that manipulate data base files in ways that are advantageous to scheduling applications. Originally designed for the Space Shuttle flight schedule, the program can be easily modified for other scheduling situations. Schedule Organizer provides a simple method for generating distribution lists. These distribution lists contain readers' names for each task schedule defined by the input files. Schedule Tracker provides an effective method for tracking tasks that are 'past due' and/or 'near term'. ST generates reports for each responsible staff member with one or more assigned tasks that fall within the two listed categories. This enables an engineering manager to monitor tasks assigned to staff by running ST on a weekly basis. ST only lists tasks on reports that have become past due or are scheduled for recent completion (near term). Schedule Report Generator provides a simple method for generating periodic schedule reports. ST and SRG use the same data base file as input. The common data base file has a maximum number of 400 entries. The time span of all three programs is nineteen months. Both of these maximum numbers can be modified by the user.

    We report a case of segmental uniparental maternal hetero- and isodisomy involving the whole of chromosome 6 (mat-hUPD6 and mat-iUPD6) and a cullin 7 (CUL7) gene mutation in a Japanese patient with 3M syndrome. 3M syndrome is a rare autosomal recessive disorder characterized by severe pre- and postnatal growth retardation that was recently reported to involve mutations in the CUL7 or obscurin-like 1 (OBSL1) genes. We encountered a patient with severe growth retardation, an inverted triangular gloomy face, an inverted triangle-shaped head, slender long bones, inguinal hernia, hydrocele testis, mild ventricular enlargement, and mild mental retardation. Sequence analysis of the CUL7 gene of the patient revealed a homozygous missense mutation, c.2975G>C. Genotype analysis using a single nucleotide polymorphism array revealed two mat-hUPD and two mat-iUPD regions involving the whole of chromosome 6 and encompassing CUL7. 3M syndrome caused by complete paternal iUPD of chromosome 6 involving a CUL7 mutation has been reported, but there have been no reports describing 3M syndrome with maternal UPD of chromosome 6. Our results represent a combination of iUPDs and hUPDs from maternal chromosome 6 involving a CUL7 mutation causing 3M syndrome. PMID:21166787

    This Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image of Mount St. Helens was captured one week after the March 8, 2005, ash and steam eruption, the latest activity since the volcano's reawakening in September 2004. The new lava dome in the southeast part of the crater is clearly visible, highlighted by red areas where ASTER's infrared channels detected hot spots from incandescent lava. The new lava dome is 155 meters (500 feet) higher than the old lava dome, and still growing.

    With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet.

    ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

    The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

  6. Properties near magnetic instability of heavy-electron compounds Ce3M4Sn13 and La3M4Sn13, with M=Co, Rh and Ru

    In this review, we report the thermodynamic, magnetic and electronic transport properties of the skutterudite-related Ce3M4Sn13 and La3M4Sn13 intermetallic compounds with M = Co, Rh and Ru, which display a variety of behaviours. Ce3M4Sn13 exhibit a large increase in C/T with a maximum value of about 4 JK-2mol-1Ce due to strong electron and short-range magnetic correlations. These compounds show a crossover from a magnetically correlated heavy-fermion state to a single impurity state in applied magnetic fields. In order to study the proximity of Ce3Co4Sn13 to the possible magnetic quantum critical point (QCP), we investigated the system of Ce3-xLaxCo4Sn13 alloys. We found the critical concentration ?, which separates the magnetically correlated state (?) from a single impurity state (?), however the low-T C(T)/T and the magnetic susceptibility behaviours are not characteristic of the QCP. With increasing of the magnetic field, resistivity follows power law behaviour for the samples ?, with n strongly field dependent. The ?-anomaly is discussed on the base of spin-fluctuation theory of Moriya and Takimoto. Specific heat data show that La3M4Sn13 are typical BCS superconductors, however, La3Rh4Sn13 and La3Ru4Sn13 exhibit a second superconducting phase, characteristic of inhomogeneous superconductors.

  7. Petrology and Geochemistry of Plagioclase-Phyric Basaltic Lava Flows on St. George Island, Alaska: Evidence for a Genetic Link Between Magmatic Centers of the Pribilof Islands

    St. George and St. Paul Islands, the two largest Pribilof Islands (Alaska), are located 70 km apart in the Bering Sea 400-450 km north of the Aleutian arc front. The islands are centers of alkaline basaltic volcanism associated with the diffuse Bering Sea basalt province. On St. George an extensive history of volcanism (~2.6-1.4 Ma; Mukasa and Andronikov, JGR, submitted) is exposed in high sea cliffs and several NE-SW and E-W trending fault blocks that define the present topography of the island. In contrast, St. Paul is a potentially active volcanic center (~550-3 ka) with numerous young tephra cones and associated lava flows that show minimal erosion and deformation by faulting. Volcanic rocks erupted on St. George are mainly olivine- + clinopyroxene-phyric basalts and trachy-basalts with high to moderate MgO contents (12-8 wt%). In addition, distinct plagioclase-phyric lavas are present at high stratigraphic levels. The plagioclase-phyric lavas are relatively evolved with 47-51 wt% SiO2 and 6.6-4.9 wt% MgO. Chondrite-normalized REE patterns are LREE-enriched with little to no Eu anomalies (Eu/Eu* = 1.03-1.06), indicating that the evolved compositions and plagioclase-rich nature of the flows are not due to phenocryst accumulation. Instead, production of plagioclase-phyric lavas on St. George likely involved a complex set of differentiation processes, including fractional crystallization and magma mixing. This assertion is supported by major and trace element compositions of the rocks, which define distinct trends on chemical variation diagrams relative to less evolved plagioclase-poor rocks. For example, whereas MgO contents of most St. George lavas as a group decrease with increasing SiO2 contents, these elements show a positive linear correlation for plagioclase-phyric lavas. The linear trends of these samples on chemical variation diagrams are best explained by mixing of at least two distinct evolved endmember magmas. Major element mass balance calculations

  8. Wave packet dynamics of an atomic ion in a Paul trap

    Using numerical simulations of the time-dependent Schrödinger equation, we study the full quantum dynamics of the motion of an atomic ion in a linear Paul trap. Such a trap is based on a time-varying, periodic electric field and hence corresponds to a time-dependent potential for the ion, which we model exactly. We compare the center-of-mass motion with that obtained from classical equations of motion, as well as to results based on a time-independent effective potential. We also study the oscillations of the width of the ion’s wave packet, including close to the border between stable (bounded) and unstable (unbounded) trajectories. Our results confirm that the center-of-mass motion always follows the classical trajectory, that the width of the wave packet is bounded for trapping within the stability region, and therefore that the classical trapping criterion is fully applicable to quantum motion.

    2013-12-01

    This paper deals with a short biography of Paul Dirac, his first celebrated work on quantum mechanics, his first formal systematic use of the Dirac delta function and his famous work on quantum electrodynamics and quantum statistics. Included are his first discovery of the Dirac relativistic wave equation, existence of positron and the intrinsic spin and helicity of electrons. Special attention is given to Dirac's original visionary work on the existence of the magnetic monopole, and on his Large Number Hypothesis that led to the conclusion that physical quantities universally considered as constant of nature are not really constants, but they vary with cosmological time. Some concluding remarks with personal reminiscence are added in the end of the paper.

    The BOA beamline at the Swiss spallation neutron source SINQ at Paul Scherrer Institut is a flexible instrument used mainly for testing novel techniques and devices for neutron scattering and optics, but, due to the large and relatively homogeneous field of view, it can be successfully used for experiments in the field of neutron imaging. The beamline allows also for the exploitation of advanced imaging concepts such as polarized neutron imaging and diffractive neutron imaging. In this paper we present the characterization of the BOA beamline in the light of its neutron imaging capabilities. We show also the different techniques that can be employed there as user-friendly plugins for non-standard neutron imaging experiments.

The instrument is based on a very thin gadolinium oxysulfide (Gd2O2S:Tb+) scintillator screen and a magnifying optics. The Neutron Microscope prototype has been tested at the ICON and the BOA beamlines at PSI and sub-10 μm features can be clearly resolved on a focussed ion beam (FIB) enhance test object - a gadolinium-based Siemens star. The spatial resolution of the images of the gadolinium-based Siemensstar assessed by Fourier ring correlation was about 7.6 μm. The outlook for future improvement of the Neutron Microscope system is presented.

  13. Control Of Screening Of A Charged Particle In Electrolytic Aqueous Paul Trap

    2011-06-01

    Individual charged particles could be trapped and confined by the combined radio-frequency and DC quadrupole electric field of an aqueous Paul trap. Viscosity of water improves confinement and extends the range of the trap parameters which characterize the stability of the trap. Electrolyte, if present in aqueous solution, may screen the charged particle and thus partially or fully suppress electrophoretic interaction with the applied filed, possibly reducing it to a generally much weaker dielectrophoretic interaction with an induced dipole. Applying molecular dynamics simulation we show that the quadrupole field has a different effect at the electrolyte ions and at much heavier charged particle, effectively eliminating the screening by electrolyte ions and reinstating the electrophoretic confinement.

    This paper proposes the use of the two-dimensional continuous Paul wavelet transform to extract the phase of spatial carrier fringe patterns. The proposed algorithm has been tested using computer-generated and real fringe patterns, and these tests have demonstrated the suitability of the proposed technique for the phase demodulation of fringe patterns. Additionally, this algorithm is compared to three two-dimensional continuous wavelet algorithms that have figured prominently in the literature, specifically the Morlet, advanced Morlet and fan mother wavelets. This comparison has revealed that the proposed algorithm outperforms the other three mother wavelets in terms of its suitability for extracting the phase of fringe patterns that exhibit large phase variations.

    2015-11-28

    We present models for a heteronuclear diatomic molecular ion in a linear Paul trap in a rigid-rotor approximation, one purely classical and the other where the center-of-mass motion is treated classically, while rotational motion is quantized. We study the rotational dynamics and their influence on the motion of the center-of-mass, in the presence of the coupling between the permanent dipole moment of the ion and the trapping electric field. We show that the presence of the permanent dipole moment affects the trajectory of the ion and that it departs from the Mathieu equation solution found for atomic ions. For the case of quantum rotations, we also evidence the effect of the above-mentioned coupling on the rotational states of the ion.

    The results presented here demonstrate that the Paul Trap Simulator Experiment (PTSX) simulates the propagation of intense charged particle beams over distances of many kilometers through magnetic alternating-gradient (AG) transport systems by making use of the similarity between the transverse dynamics of particles in the two systems. Plasmas have been trapped that correspond to normalized intensity parameters s = wp2 (0)/2wq2 * 0.8, where wp(r) is the plasmas frequency and wq is the average transverse focusing frequency in the smooth-focusing approximation. The measured root-mean-squared (RMS) radius of the beam is consistent with a model, equally applicable to both PTSX and AG systems that balances the average inward confining force against the outward pressure-gradient and space-charge forces. The PTSX device confines one-component cesium ion plasmas for hundreds of milliseconds, which is equivalent to over 10 km of beam propagation.

  18. Psychoanalysis, creativity, and hope: forward edge strivings in the life and work of choreographer Paul Taylor.

    2005-01-01

    Psychoanalysis and creativity are not interchangeable enterprises; however, both creativity and psychoanalysis promise the hope of transformation. But hope may be fragile. Healthy aspects of self may hide and diminish hope to protect it against invasion from toxic pathological patterns. Hope may be rekindled by an empathically responsive environment and the reengagement of healthy forward edge strivings. Psychoanalysis illustrates creativity as a conduit for hope. Modern dance choreographer Paul Taylor's 1988 autobiography, Private Domain, describes Taylor's hope and strivings through creative engagement. Unfortunately, when Taylor's body inevitably falters after years of performing, he is unprepared psychologically to cope successfully. Taylor's sense of self begins to fragment and his forward edge strivings to decay. Eventually, Taylor collapses on stage from drug addiction and illness; his performing career crashes to an end. Taylor must search for his forward edge strivings with hope. Psychoanalysis illuminates Taylor's journey to find hope, motivation, meaningful intention, and transformation through creativity and dance-making. PMID:15953780

    A new approach to β-delayed neutron spectroscopy has been demonstrated that circumvents the many limitations associated with neutron detection by instead inferring the decay branching ratios and energy spectra of the emitted neutrons by studying the nuclear recoil. Using the Beta-decay Paul Trap, fission-product ions were trapped and confined to within a 1-mm{sup 3} volume under vacuum using only electric fields. Results from recent measurements of {sup 137}I{sup +} and plans for development of a dedicated ion trap for future experiments using the intense fission fragment beams from the Californium Rare Isotope Breeder Upgrade (CARIBU) facility at Argonne National Laboratory are summarized. The improved nuclear data that can be collected is needed in many fields of basic and applied science such as nuclear energy, nuclear astrophysics, and stockpile stewardship.

    In 1877 Louis Paul Cailletet in France and Raoul Pictet in Switzerland liquefied oxygen in the form of a mist. The liquefaction of the first of the so-called permanent gases heralded the birth of low-temperature research and is often described in the literature as having started a ‘race’ for attaining progressively lower temperatures. In fact, between 1877 and 1908, when helium, the last of the permanent gases, was liquefied, there were many priority disputes—something quite characteristic of the emergence of a new research field. This paper examines Cailletet's path to the liquefaction of oxygen, as well as a debate between him and the Polish physicist Zygmunt Wróblewski over the latter's contribution to the liquefaction of gases.

    Quantum tunnelling is a common fundamental quantum mechanical phenomenon that originates from the wave-like characteristics of quantum particles. Although the quantum tunnelling effect was first observed 85 years ago, some questions regarding the dynamics of quantum tunnelling remain unresolved. Here we realize a quantum tunnelling system using two-dimensional ionic structures in a linear Paul trap. We demonstrate that the charged particles in this quantum tunnelling system are coupled to the vector potential of a magnetic field throughout the entire process, even during quantum tunnelling, as indicated by the manifestation of the Aharonov-Bohm effect in this system. The tunnelling rate of the structures periodically depends on the strength of the magnetic field, whose period is the same as the magnetic flux quantum φ0 through the rotor [(0.99 ± 0.07) × φ0].

    Dr. Paul Moore pioneered the use of high-speed cinematography for observation of normal and abnormal vocal fold vibrations during phonation. His analysis of the glottal area waveform, opening and closing speed index, and open quotient from the high-speed films were labor intensive but relevant today. With advances in digital image capture and automated image extraction techniques, stroboscopy and high-speed images of vocal fold vibration may be analyzed with objective measures. Digital high-speed image capture in color is now clinically practical at high resolution. Digital kymography now allows analysis of the vibratory waveform from each vocal fold. Serial capture and comparison can document changes in vibratory function with treatment. Quantification of vocal fold vibration using such techniques is now practical. This is a review of vocal fold vibration capture and analysis techniques since Dr. Moore. PMID:24094798

    The daily oscillations observed in most living organisms are endogenously generated with a period of 24 h, and the underlying structure of periodic oscillation is an autoregulatory transcription-translation feedback loop. The mechanisms of untranslated region (UTR)-mediated post-transcriptional regulation (e.g., mRNA degradation and internal ribosomal entry site (IRES)-mediated translation) have been suggested to fine-tune the expression of clock genes. Mouse Period3 (mPer3) is one of the paralogs of Period gene and its function is important in peripheral clocks and sleep physiology. mPer3 mRNA displays a circadian oscillation as well as a circadian phase-dependent stability, while the stability regulators still remain unknown. In this study, we identify three proteins - heterogeneous nuclear ribonucleoprotein (hnRNP) K, polypyrimidine tract-binding protein (PTB), and hnRNP D - that bind to mPer3 mRNA 3'-UTR. We show that hnRNP K is a stabilizer that increases the amplitude of circadian mPer3 mRNA oscillation and hnRNP D is a destabilizer that decreases it, while PTB exhibits no effect on mPer3 mRNA expression. Our experiments describe their cytoplasmic roles for the mRNA stability regulation and the circadian amplitude formation. Moreover, our mathematical model suggests a mechanism through which post-transcriptional mRNA stability modulation provides not only the flexibility of oscillation amplitude, but also the robustness of the period and the phase for circadian mPer3 expression. Mouse Period3 (mPer3) is one of well-known clock genes. We identified three 3'-UTR-binding proteins that modulate the mRNA stability, and they influenced to the amplitude of circadian mPer3 mRNA oscillation. Our mathematical model not only showed the relationship between mRNA stability and its oscillation profile but provided the molecular mechanism for the robustness of the period and the phase in circadian oscillation. hnK, heterogeneous nuclear ribonucleoprotein (hnRNP) K; hnD, hn

    We discuss a new program of carrying out high precision VRI CCD photometry of several star clusters of different ages. The photometry is being carried out using the 1.3 m Robotically Controlled Telescope (RCT), located at KPNO. This program focuses on the study of variable stars in mostly open clusters. Selected astrophysically important eclipsing binaries, pulsating variables, blue stragglers, and chromospherically active variable stars will be studied. Also, searches of new variable stars will be made from the expected large samples of cluster stars. For example, photometry is planned of the several W UMa eclipsing binaries and blue straggler stars in the old open cluster NGC 188. Photometry also will be carried out of the young open cluster NGC 7790. This cluster is unique because has three confirmed classical cepheid members: CE Cas A (V ˜ +10.9 mag; F8 Ib; P = 4.446 d ), CE Cep B (V ˜ +11.0 mag; F9 Ib; 5.128 d), and CF Cas (V ˜ +11.1 mag; F8 Ib; 4.875 d). NGC 7790 also contains the 10th mag eccentric B0+B0 eclipsing binary QX Cas. The observations of QX Cas are being conducted to determine the accurate distance to this star and thus to the cluster and its cepheid members. When complete these observations, combined with spectroscopy, will permit a reliable calibration of the ``zero-point'' of the galactic cepheid Period-Luminosity Law. Another possible project is the search of light variations of PMS stars and chromospherically active stars (from star spot rotational modulations) in young clusters such as the alpha Perseus Cluster, h & χ Per, M34, and the Pleiades. Refurbishment of the RCT has been made possible by NASA grant NAG 58762. The RCT Consortium includes: Western Kentucky Univ., S. Carolina St Univ., Francis Marion Univ., Villanova Univ., and the Planetary Science Institute (PSI).

  16. ST-segment elevation: Distinguishing ST elevation myocardial infarction from ST elevation secondary to nonischemic etiologies

    2014-01-01

    The benefits of early perfusion in ST elevation myocardial infarctions (STEMI) are established; however, early perfusion of non-ST elevation myocardial infarctions has not been shown to be beneficial. In addition, ST elevation (STE) caused by conditions other than acute ischemia is common. Non-ischemic STE may be confused as STEMI, but can also mask STEMI on electrocardiogram (ECG). As a result, activating the primary percutaneous coronary intervention (pPCI) protocol often depends on determining which ST elevation patterns reflect transmural infarction due to acute coronary artery thrombosis. Coordination of interpreting the ECG in its clinical context and appropriately activating the pPCI protocol has proved a difficult task in borderline cases. But its importance cannot be ignored, as reflected in the 2013 American College of Cardiology Foundation/American Heart Association guidelines concerning the treatment of ST elevation myocardial infarction. Multiples strategies have been tested and studied, and are currently being further perfected. No matter the strategy, at the heart of delivering the best care lies rapid and accurate interpretation of the ECG. Here, we present the different patterns of non-ischemic STE and methods of distinguishing between them. In writing this paper, we hope for quicker and better stratification of patients with STE on ECG, which will lead to be better outcomes. PMID:25349651

    Pure samples of Na2TeS3 and Na2TeSe3 were synthesized by the reactions of stoichiometric amounts of the elements Na, Te, and Q (Q = S, Se) in the ratio 2:1:3. Both compounds are highly air- and moisture-sensitive. The crystal structures were determined by single-crystal X-ray diffraction. Yellow Na2TeS3 crystallizes in the space group P21/c. Na2TeSe3 exists in a low-temperature modification (Na2TeSe3-mP24, space group P21/c) and a high-temperature modification (Na2TeSe3-mC48, space group C2/c); both modifications are red. Density functional theory calculations confirmed the coexistence of both modifications of Na2TeSe3 because they are very close in energy (ΔE = 0.18 kJ mol(-1)). To the contrary, hypothetic Na2TeS3-mC48 is significantly less favored (ΔE = 1.8 kJ mol(-1)) than the primitive modification. Na2TeS3 and Na2TeSe3-mP24 are isotypic to Li2TeS3, whereas Na2TeSe3-mC48 crystallizes in its own structure type, which was first described by Eisenmann and Zagler. The title compounds have two common structure motifs. Trigonal TeQ3 pyramids form layers, and the Na atoms are surrounded by a distorted octahedral environment of chalcogen atoms. Raman spectra are dominated by the vibration modes of the TeQ3 units. The activation energies of the total conductivity of the title compounds range between 0.68 eV (Na2TeS3) and 1.1 eV (Na2TeSe3). Direct principal band gaps of 1.20 and 1.72 eV were calculated for Na2TeSe3 and Na2TeS3, respectively. The optical band gaps are in the range from 1.38 eV for Li2TeSe3 to 2.35 eV for Na2TeS3.

    Assessment of legal age, also known as age of majority, is a controversial issue as there are few body biomarkers or evidence during late adolescence differentiating a subject from being a minor or adult. The third molar was recognized as a suitable site for age examination in late adolescence. We analyzed the development of the left mandibular third molar by the third molar maturity index (I3M) and a specific cut-off value of I3M = 0.08, established by Cameriere et al. in 2008 and used it for discriminating between minors and adult black Africans from Gaborone, Botswana. A final sample of panoramic radiographs (OPTs) of 1294 people (582 males and 712 females) aged between 13 and 23 years was evaluated. The real age decreased as I3M gradually increased. There was no statistically significant difference in the third molar development evaluated using I3M between males and females (p > 0.05) across different I3M classes. Results of 2 × 2 contingency tables for different cut-off values indicated that I3M = 0.08 was useful in discriminating between adults and minors. Precisely, for I3M = 0.08, the values of accuracy or overall fraction of correctly classified were 0.91 in males with a 95 % confidence interval (95 % CI) of 0.88 to 0.93 and 0.92 (95 % CI, 0.90 to 0.93) in females. Values of sensitivity of the test or the proportion of participants being 18 years and older were 0.88 (95 % CI, 0.87 to 0.90) in males and 0.88 (95 % CI, 0.90 to 0.93) in females, while values of specificity or proportion of individuals younger than 18 who have I3M <0.08 were 0.94 (95 % CI, 0.91 to 0.96) in males and 0.96 (95 % CI, 0.94 to 0.98) in females. Positive predictive values of the test, where the participants whose I3M <0.08 were adults, were 0.94 (95 % CI 0.91 to 0.96) in males and 0.97 (95 % CI, 0.94 to 0.98) in females, while negative predictive values of the test, where the participants whose I3M was ≥0.08 were minors, were 0.88 (95 % CI 0.85 to

    In this paper we consider a family of 3m-indices generalizations of the classical Mittag-Leffler function, called multi-index (3m-parametric) Mittag-Leffler functions. We survey the basic properties of these entire functions, find their order and type, and new representations by means of Mellin-Barnes type contour integrals, Wright pΨq-functions and Fox H-functions, asymptotic estimates. Formulas for integer and fractional order integration and differentiations are found, and these are extended also for the operators of the generalized fractional calculus (multiple Erdélyi-Kober operators). Some interesting particular cases of the multi-index Mittag-Leffler functions are discussed. The convergence of series of such type functions in the complex plane is considered, and analogues of the Cauchy-Hadamard, Abel, Tauber and Littlewood theorems are provided.

    In the present study, we show that the heterogeneous mixture of glycoforms of the basic salivary proline-rich protein 3M, encoded by PRB3-M locus, is a major component of the acidic soluble fraction of human whole saliva in the first years of life. Reversed-phase high-performance liquid chromatography with high-resolution electrospray ionization mass spectrometry analysis of the intact proteoforms before and after N-deglycosylation with Peptide-N-Glycosidase F and tandem mass spectrometry sequencing of peptides obtained after Endoproteinase GluC digestion allowed the structural characterization of the peptide backbone and identification of N- and O-glycosylation sites. The heterogeneous mixture of the proteoforms derives from the combination of 8 different neutral and sialylated glycans O-linked to Threonine 50, and 33 different glycans N-linked to Asparagine residues at positions 66, 87, 108, 129, 150, 171, 192, and 213.

    Recharge estimates, which generally varied within 10 in./yr for each of the methods, generally were largest based on the precipitation, ground-water level fluctuation, and age dating of shallow ground water methods, slightly smaller based on the streamflow-recession displacement method, and smallest based on the watershed characteristics method. Leakage, which was less than 1 in./yr, varied within 1 order of magnitude based on the ground-water level fluctuation method and as much as 4 orders of magnitude based on analyses of vertical-hydraulic gradients.

    Site design, including capacity relative to drainage area and soil permeability, is an important consideration in the efficiency of rain-garden operation. Vegetation type likely affects the infiltration capacity, nutrient uptake, and evapotranspiration of a rain garden and probably the resulting water quality. The long-term efficiency of rain gardens is difficult to determine from the results of this study because most are still evolving and maturing in relation to their hydrologic, biologic, and chemical setting. Many resource managers have questioned what long-term maintenance will be needed to keep rain gardens operating effectively. Additional or continued studies could address many of these concerns.

  7. Evaluation of heterogeneity statistics as reasonable proxies of the error of precipitation quantile estimation in the Minneapolis-St. Paul region

    Estimating precipitation frequency is important in engineering, agriculture, land use planning, and many other disciplines. The index flood method alleviates small sample size issues due to short record length by calculating normalized quantile estimates for averaged data from a “region” of gauges. For a perfectly homogeneous region this adds no error; heterogeneity statistics seek to quantify a real-world region’s deviation from this assumption. Hosking and Wallis (1997) introduced a Monte Carlo heterogeneity statistic called here H1 and used a simulation study to assess its utility while rejecting two similar statistics called here H2 and H3. A nearly linear relationship was found between H1 and the percentage root mean square error (RMSE) increase due to heterogeneity, establishing H1 as a “reasonable proxy” of quantile error. The H1-percent RMSE added relationship found in the simulation experiment was used to find equivalent RMSEs for heterogeneity thresholds against which all three H statistics were tested. In this study the “reasonable proxy” relationship is evaluated across a highly skewed daily precipitation dataset in Minnesota for H1,H2 and H3. Simulated regions used in quantile error estimation are generated using at-site L-moment ratios scaled toward the regional mean with a shrinkage multiplier. A linear relationship is found between Monte Carlo estimates of quantile RMSE and both H1 and H2 across all possible regionalizations of twelve gauges. H2’s relationship is less linear than H1’s as quantified by Pearson’s r. A synthetic study is also undertaken using the same sample sizes, regional L-moment averages, and between-site variations as the Hosking and Wallis (1997) simulation. The H2-percent RMSE added relationship is found to be nearly as linear as for H1, complementing the enumeration study’s findings. Because H2’s linear relationship with percent RMSE added has approximately one-fourth the slope of theH1-RMSE relationship, heterogeneity thresholds calculated with reference to H1 should not be applied to H2. H2 thresholds can be derived from the H2-percent RMSE added relationship in analogous fashion to the method used in Hosking and Wallis (1997) for H1. The resulting thresholds are one-fourth the magnitude of the H1 thresholds.

    An Hα camera has been designed and installed in the U-3M torsatron for spatially and temporally resolved measurements. This device provides fast measurements of the emission brightness profile in the noisy environment of the radio frequency (RF) heated plasma. Unusual topology of diagnostics and the data acquisition system are applied. All the system components, including digitizers, are assembled in a single unit. It allows the suppression of a low-frequency electromagnetic interference by eliminating the ground loops. And the suppression of RF noises is achieved by eliminating the signal interface cables and digital interface cables in the design. The Wi-Fi interface is used to prevent a ground loop in the data transfer stage. The achieved sensitivity of our diagnostics is high enough for measuring the Hα emission from the low-density (ne ≈ (1-2)ṡ1010 cm-3) plasma with a temporal resolution of about 20 μs in the noisy environment. Different types of Hα emission fluctuations within the frequency range of 1-5 kHz and poloidal mode numbers m = 0 and m = 5 have been observed in U-3M. A simple technique of the line-of-sight data analysis, based on the U-3M magnetic surface asymmetry, is proposed and used for the spatial localization of the rotating mode and for the determination of mode numbers and its poloidal rotation direction using a single Hα array.

    2016-04-01

    During recent years, a number of tools based on Structure-from-Motion algorithms have been released for full image-based 3D reconstruction either freely (e.g. Bundler, PMVS2, VisualSFM, MicMac) or commercially (e.g. Agisoft PhotoScan). The SF3M interface was developed in Matlab® to use link software developments (VisualSFM, CloudCompare) and new applications to create a semi-automated workflow including reconstruction, georeferencing and point-cloud filtering, and has been tested for gully erosion assessment with terrestrial images (Castillo et al., 2015). The main aim of this work to provide an improved freely-available and easy-to-use alternative for 3D reconstruction intended for public agencies, non-profit organisations, researchers and other stakeholders interested in 3D modelling. In this communication we present SF3M 2.0, a new version of the graphical user interface. In this case, the SfM module is based on MicMac, an open-software tool (Pierrot-Deseilligny and Cléry, 2011) which provides advanced features such as camera calibration and constrained bundle adjustment using ground control points. SF3M 2.0 will be tested in two scenarios: a) using the same ground-based image set tested in Castillo et al. (2015) to compare the performance of both versions and b) using aerial images taken from a helium balloon to assess a gully network in a 40-hectares catchment. In this study we explore the advantages of SF3M 2.0, explain its operation and evaluate its accuracy and performance. This tool will be also available for free download.

    2012-02-01

    We present excerpts from three archival ultra high-speed films on the function of the human larynx by Paul Moore, Ph. D. and Hans von Leden, M.D. The films received two awards for best scientific cinematography from two different international film festivals in Italy in 1957. These films present ultra high-speed cinematographic accounts on the workings of the human vocal folds during various phonatory and ventilatory activities. These films were captured at speeds of 2000 to 5000 frames-per-second via an ingeniously arranged laryngeal mirror viewing device. Such speeds were revolutionary six decades ago. Technology currently allows us to film laryngeal behavior at speeds of up to 16,000 frames-per-second using digital recordings. However, the ultra high-speed films by Paul and Hans remain a beacon for anyone sincerely interested in how the smallest instrument of sound production works, and how it is subjected to failure by intrinsic or extrinsic factors.

    The eminent Greek physician Paul of Aegina, native of the Saronic island Aegina and pupil of the Alexandrian School, understood both exotropia and endotropia, his designation for esotropia and proposed therapeutic measures for their treatment during baby or toddler age. He had introduced an innovative method for the newborns to have a straight vision, "the congenital strabismus of the newborns must be treated with the placement of a facial mask (with 2 open holes in the middle axes of the eyes), so that the babies could only see in a straight line", combined with a small oil lamp to assure a direct eye alignment. Although not even a diagram of the masks was saved until nowadays, Paul was the first to suggest the early correction of the eyes deviation, and considered to be the father of orthoptics.

As such I believe she would concur with the focus of my remarks on the partners in our work: our clients. PMID:27220742

  6. The Age of Miracle and Wonders: Paul Simon and the Changing American Dream.

    The American dream altered. In the 19th century, it was focused on male success in the marketplace. With the rise of the consumer culture, ideals changed. Women were brought in, as companionate marriage, home ownership, and a successful domestic life with children became central in American life. Since the mid-sixties, singer-songwriter Paul Simon has been writing songs reflecting these changes. He has two songs with America in the title, and is one of the few rock stars that write extensively about marriage and parenting. He also writes about love as romance, with a spouse, and towards offspring. Simon too composes songs about affluence, technology, and what brings happiness and joy. His work illuminates the United States in what he says is "the age's most uncertain hour." He believed that affluence was a key to our fulfillment. The changes in American life since the 1970s, show that much of what was held as ideal, has been through troubled times. We can gain insight into the fate of the American dream through Simon's songs.

    Paul trap working in the second stability region has long been recognized as a possible approach for achieving high-resolution mass spectrometry (MS), which however is still far away from the experimental implementations because of the narrow working area and inefficient ion trapping. Full understanding of the ion motional behavior is helpful for solving the problem. In this article, the ion motion in a superimposed octopole field, which was characterized by the nonlinear Mathieu equation, was solved analytically using Poincare-Lighthill-Kuo (PLK) method. This method equivalently described the nonlinear disturbance by an effective quadrupole field with perturbed Mathieu parameters, a(u) and q(u), which would bring huge convenience in the studies of nonlinear ion dynamics and was, therefore, used for rapid evaluation of the nonlinear effects of ion motion. Fourth-order Runge-Kutta method (4th R-K) indicated the error of PLK for characterizing the frequency shift of ion motion was within 15%. PMID:25183226

  8. Conspiracies of immanence: Paul Tillich, Pierre Teilhard de Chardin and C.G. Jung.

    Jung's psychology proffers a sustained reflection on the traditional religious question of the relation of divine transcendence to immanence. On this issue his psychology affirms a position of radical immanence in its contention that the experience of divinity is initially wholly from within. Though this position remains on the periphery of religious and theological orthodoxy Jung is not alone in holding it among moderns. Paul Tillich adopts a similar stance with his controlling symbols of the divine as 'Ground of Being' and 'Depth of Reason'. Pierre Teilhard de Chardin understands divinity as the experiential energy of evolution itself working within nature and humanity toward greater configurations of universal communion as the basis of community. All of Jung's master symbols of individuation assume such an understanding of immanence uniting individual and totality. His psychology strongly suggests and contributes to the current emergence of a new religious sensitivity based on the awareness of the intra-psychic origin of all religions. In his later writings he held out such a position as a significant alternative to genocide. PMID:25610962

    Projective readout of quantum information stored in atomic qubits typically uses state-dependent CW laser-induced fluorescence. This method requires an often sophisticated imaging system to spatially filter out the background CW laser light. We present an alternative approach that instead uses simple pulse sequences from a mode-locked laser to affect the same state-dependent excitations in less than 1 ns. The resulting atomic fluorescence occurs in the dark, allowing the placement of non-imaging detectors right next to the atom to improve the qubit state detection efficiency and speed. We also study 2D Coulomb crystals of atomic ions in an oblate Paul trap. We find that crystals with hundreds of ions can be held in the trap, potentially offering an alternative to the use of Penning traps for the quantum simulation of 2D lattice spin models. We discuss the classical physics of these crystals and the metastable states that are supported in 2D. This work is supported by the US Army Research Office.

    The cold neutron spectrum of the Beamline for neutron Optics and other Applications (BOA) at Paul Scherrer Institut enables high contrast neutron imaging because neutron cross sections for many materials increase with neutron wavelength. However, for many neutron imaging applications, spatial resolution can be as important as contrast. In this paper the neutron transmission imaging capabilities of an MCP/Timepix detector installed at the BOA beamline are presented, demonstrating the possibilities for studying sub-20 μm features in various samples. In addition to conventional neutron radiography and microtomography, the high degree of neutron polarization at the BOA beamline can be very attractive for imaging of magnetic fields, as demonstrated by our measurements. We also show that a collimated cold neutron beamline combined with a high resolution detector can produce image artifacts, (e.g. edge enhancements) due to neutron refraction and scattering. The results of our experiments indicate that the BOA beamline is a valuable addition to neutron imaging facilities, providing improved and sometimes unique capabilities for non-destructive studies with cold neutrons.

  11. Paul Gray's narrowing scope: a "developmental lag" in his theory and technique.

    PubMed

    Phillips, Sidney H

    2006-01-01

    A cental thesis of Paul Gray's work is that a "developmental lag" pervades modern psychoanalysis in its failure to assimilate and apply knowledge gained about the role of the unconscious ego in intrapsychic life. But Gray himself, it is proposed, has become a victim of a new "developmental lag," of his own construction. As he somewhat single-mindedly pursued the ramifications of his "developmental lag" concept, Gray may have foreclosed on some noteworthy ideas developing around him. The most important example is his claim--herein refuted--that proper interpretive technique can avoid being infused with transference. He also seems to have rejected the theoretical importance of the internalization of the analyst and the clinical usefulness of countertransference. While emphasizing defense analysis, he ignores defenses such as splitting, denial, and disavowal as substantive problems for his technique of close-process attention. Gray's "undoing" of the rapprochement between "ego analysis" and "id analysis" by viewing the matter as an either-or proposition undermines the very real value of his contribution to the field.

    The Proton Irradiation Facility (PIF) has been designed and constructed, in cooperation between Paul Scherrer Institute (PSI) and European Space Agency (ESA), for terrestrial proton testing of components and materials for spacecraft. Emphasis has been given to generating realistic proton spectra encountered by space-flights at any potential orbit. The facility, designed in a user-friendly manner, can be readily adapted to the individual requirements of experimenters. It is available for general use serving also in testing of radiation monitors and for proton experiments in different scientific disciplines. The Radiation Environment Monitor REM has been developed for measurements of the spacecraft radiation conditions. Two instruments were launched into space, one into a Geo-stationary Transfer Orbit on board of the STRV-1b satellite and one into a Low Earth Orbit on the Russian MIR station. The next generation of monitors (SREMs--Standard REMs) is currently under development in partnership of ESA, PSI and Contraves-Space. They will operate both as minimum intrusive monitors, which provide radiation housekeeping data and alert the spacecraft when the radiation level crosses allowed limits and as small scientific devices measuring particle spectra and fluxes. Future missions as e.g. INTEGRAL, STRV-1c and PROBA will be equipped with new SREMs. PMID:11770526

    Miniature gas chromatography (GC) and miniature mass spectrometry (MS) instrumentation has been developed to identify and quantify the chemical compounds present in complex mixtures of gases. The design approach utilizes micro-GC components coupled with a Paul quadrupole ion trap (QIT) mass spectrometer. Inherent to the system are high sensitivity, good dynamic range, good QIT resolution, low GC flow-rates to minimize vacuum requirements and the need for consumables; and the use of a modular approach to adapt to volatile organic compounds dissolved in water or present in sediment. Measurements are reported on system response to gaseous species at concentrations varying over four orders of magnitude. The ability of the system to deal with complicated mixtures is demonstrated, and future improvements are discussed. The GC/QIT system described herein has a mass, volume and power that are, conservatively, one-twentieth of those of commercial off-the-shelf systems. Potential applications are to spacecraft cabin-air monitoring, robotic planetary exploration and trace-species detection for residual gas analysis and environmental monitoring.

    Background The DePaul Symptom Questionnaire (DSQ) was developed to provide a structured approach for collecting standardized symptomatology and health history information to allow researchers and clinicians to determine whether a patient meets the diagnostic criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), myalgic encephalomyelitis (ME), and/or chronic fatigue syndrome (CFS). Purpose The purpose of this study was to examine the test-retest reliability of the DSQ. Methods Test-retest reliability of the measure was examined with a sample of 26 adults self-identifying as having either ME/CFS, ME and/or CFS and 25 adults who did not self-identify as having these illnesses and were otherwise healthy controls. Results Overall, the majority of items on the DSQ exhibited good to excellent test-retest reliability, with Pearson’s or kappa correlation coefficients that were 0.70 or higher. Conclusions Thus, the present study suggests that the DSQ is a reliable diagnostic measure that can provide a standardized way of examining illness constructs and symptomatology among patients who identify as having ME/CFS, ME and/or CFS.

    We report on the construction and characterization of an apparatus for quantum information experiments using 88Sr+ ions. A miniature linear radio-frequency (rf) Paul trap was designed and built. Trap frequencies above 1 MHz in all directions are obtained with 50 V on the trap end-caps and less than 1 W of rf power. We encode a quantum bit (qubit) in the two spin states of the S 1/2 electronic ground-state of the ion. We constructed all the necessary laser sources for laser cooling and full coherent manipulation of the ions' external and internal states. Oscillating magnetic fields are used for coherent spin rotations. High-fidelity readout as well as a coherence time of 2.5 ms are demonstrated. Following resolved sideband cooling the average axial vibrational quanta of a single trapped ion is bar{n}=0.05 and a heating rate of dot{bar{n}}=0.016 ms^{-1} is measured.

    It is well known that ions stored in a Paul trap, one of the most versatile tools in atomic, molecular, and optical (AMO) physics, may undergo a transition from a disordered cloud state to a geometrically well-ordered crystalline state, the Wigner crystal. In this paper we predict that close to the transition, the average lifetime τ¯m of the metastable cloud follows a power law, τ¯m˜(γ-γc) -β , where γc is the value of the damping constant at which the transition occurs. The exponent β depends on the trap control parameter q , but is independent of both the number of particles N stored in the trap and the trap control parameter a , which determines the shape (oblate, prolate, or spherical) of the ion cloud. In addition, we find that for given a and q , γc scales approximately like γc=C ln[ln(N ) ] +D as a function of N , where C and D are constants. Our predictions may be tested experimentally with equipment already available at many AMO laboratories. In addition to their importance in AMO trap physics, we also discuss possible applications of our results to other periodically driven many-particle systems, such as, e.g., particle accelerator beams, and, based on our trap results, conjecture that power laws characterize the phase transition to the Wigner crystal in all such systems.

  18. Models for biological research: the theory and practice of Paul Ehrlich.

    PubMed

    Travis, Anthony S

    2008-01-01

    In the late-nineteenth and early-twentieth centuries, the study of the living world placed considerable reliance on applied chemistry and chemical concepts. Paul Ehrlich, the subject of this paper, adopted from the mid-1870s principles of organic chemistry to devise procedures for use in histology, to suggest features of cellular structure, and to draw up cartoons that explained the nature of immunity. From a distinctly molecular basis, he devised meaningful experimental strategies and was inspired to develop speculative but effective theoretical models along the same lines that chemists had used to resolve problems of molecular structure and behavior. Thus, Ehrlich suggested that combining power and toxicity were independent properties of the antigen toxin. He succeeded to classify synthetic dyestuffs as stains, to use them for investigating molecular combustion, to adapt theories of dyeing to develop models for both combustion and immunity, and to exploit the properties of dyes in the development of chemotherapy. Ehrlich not only speculated on the behavior of synthetic chemicals toward his model of the protoplasm but also invoked biological specificity, a concept that would have a tremendous impact on immunology, drug development, and molecular biology.

    There emerges a world epidemic of diabetes, afflicting over 3.8 billion people globally. The socio-economic burden of this disorder is tremendous and there is an urgent need to solve the problems incurred from this disorder and to establish an efficient way of prevention and treatment. Fundamental pathology of diabetes has been too diverse to reach a simple etiology and the mechanisms of how the lesions specific to diabetes develop are yet to be clear. Nevertheless, there has been slow but significant advancement in the understanding of the disease based on characterization of the salient features of pathological lesions in human diabetic subjects. Progressive decline of islet β cells associated with increased α cell volume density was found to account for clinical manifestation of hypoinsulinemia and hyperglucagonemia in type 2 diabetes. Concurrently, signs of complications represented by distal nerve fiber loss in the skin commences from the beginning of this disease. Thus the pathological studies disclosed the major attributes in this disorder targeting the islet of pancreas and epidermal nerve, both of which were discovered by Paul Langerhans more than 140 years ago. In this review, I attempt to summarize the progress in pathology of diabetes which Langerhans opened this field. PMID:25708009

    The present investigation observed the sealing ability of low shrinkage composite resins in large and deep cavities, placed and photocured in one increment. Large, deep cavities (5.0 mm diameter and 2.5 mm deep) surrounded by enamel were prepared in bovine teeth, which were then divided into five groups. Groups 1, 2, 3 and 4: acid conditioning + Adper Single Bond (3M/ESPE, St Paul, MN, USA) and restoration with Aelite LS Posterior (BISCO Inc. Schaumburg, IL, USA) (G1); Filtek Z-350 (3M/ESPE,St Paul, MN, USA) (G2); Filtek Z-350 Flow (3M/ESPE, St Paul, MN, USA) (G3); Premisa (KERR Corporation, Orange, CA, USA) (G4). Group 5: Silorane Adhesive system (3M/ESPE, St Paul, MN, USA) + restoration with Filtek Low Shrinkage Posterior P90 (3M/ESPE, St Paul, MN, USA). After polymerization, the teeth were immersed in 0.5% basic fuchsine solution and immediately washed. Using the Imagetool Software, the extent of dye along the margins was calculated as a percentage of total perimeter. The restorations were then transversally sectioned and the depth of dye penetration was calculated in mm, using the same software. Kruskal-Wallis analysis for all groups showed no statistical differences for extent (p = 0.54) or depth (p = 0.8364) of dye penetration. According to this methodology, the so-called low shrinkage composite resins had the same sealing ability compared to regular and flowable nanocomposite materials. PMID:21359445

    In 2006, in response to the high maternal mortality, driven largely by unsafe abortions, the government of Ghana, in partnership with other organizations, launched the reducing maternal mortality and morbidity (R3M) programme in seven districts in Greater Accra, Ashanti and Eastern, to improve comprehensive abortion care services. This article examines whether this intervention made a difference to the provision of safe abortion services and postabortion care (PAC). We also examine the role played by provider attitudes and knowledge of the abortion law, on providers with clinical training in service provision. Primary data on health care providers in Ghana, collected using a quasi-experimental design, were analysed using propensity score weighting. Apart from the treatment group, the sample included two controls: (1) Districts in Accra, Ashanti and Eastern, not exposed to the treatment; and (2) Districts from distant Brong Ahafo, also not exposed to the treatment. The findings show that providers in the treatment group are nearly 16 times as likely to provide safe abortions compared with their peers in Brong Ahafo, and ∼2.5 times as likely compared with providers in the other control group. R3M providers were also different from their peers in providing PAC. Associations between provider attitudes and knowledge of the law on both outcomes were either non-significant or inconsistent including for providers with clinical knowledge of abortion provision. Provider confidence however is strongly associated with service provision. We conclude that the R3M programme is helping safe abortion provision, with the differences being greater with control groups that are geographically distant, perhaps owing to lower contamination from movement of providers between facilities. Increasing provider confidence is key to improving both safe abortion provision and PAC. PMID:25261230

    2016-01-01

    ABSTRACT MCPIP1 and IER3 are recently described proteins essential for maintenance of immune homeostasis. IER3 is involved in the regulation of apoptosis and differentiation and has been shown lately to protect activated T cells and macrophages from apoptosis. MCPIP1 is an RNase critical for controlling inflammation-related mRNAs. MCPIP1 interacts with and degrades a set of stem-loop-containing mRNAs (including IL-6). Our results demonstrate the involvement of MCPIP1 in the regulation of IER3 mRNA levels. A dual luciferase assay revealed that over-expression of MCPIP1 resulted in a decrease of luciferase activity in the samples co-transfected with constructs containing luciferase CDS attached to IER3 3′UTR. We identified a stem-loop structure similar to that described to be important for destabilization of the IL-6 mRNA by MCPIP1. Examination of IER3 3′UTR sequence, structure and evolutionary conservation revealed that the identified stem-loop is buried within a bigger element. Deletion of this fragment abolished the regulation of IER3 3′UTR-containing transcript by MCPIP1. Finally, using immunofluorescence-combined single-molecule RNA FISH we have shown that the MCPIP1 protein co-localizes with IER3 mRNA. By this method we also proved that the presence of the wild-type NYN/PIN-like domain of MCPIP1 correlated with the decreased level of IER3 mRNA. RNA immunoprecipitation further confirmed the interaction of MCPIP1 with IER3 transcripts in vivo. PMID:27256408

    The mutual transformation of light waves in the case of their simultaneous diffraction from a bulk reflection phase hologram, which was formed in a cubic photorefractive crystal of the 4-bar 3m symmetry class, has been studied. The indicator surfaces of the polarization-optimized values of the relative intensity of the object wave, which make it possible to determine the amplification of this wave for any crystal cut, are constructed. The linear polarization azimuths at which the energy exchange between the light waves reaches a maximum are found numerically for crystals of different cuts.

    Aim: Recent evidence shows that localization of mRNAs and their protein products at cellular protrusions plays a decisive function in the metastasis of cancer cells. The aim of this study was to identify the variety of proteins encoded by protrusion-localized mRNAs and their roles in the metastasis and invasion of liver cancer cells. Methods: Highly metastatic hepatocellular carcinoma cell line HCCLM3 and non-metastatic hepatocellular carcinoma cell line SMMC-7721 were examined. Cell protrusions (Ps) were separated from cell bodies (CB) using a Boyden chamber assay; total mRNA population in CB and Ps fractions was analyzed using high-throughput direct RNA sequencing. The localization of STAT3 mRNA and protein at Ps was confirmed using RT-qPCR, RNA FISH, and immunofluorescence assays. Cell migration capacity and invasiveness of HCCLM3 cells were evaluated using MTT, wound healing migration and in vitro invasion assays. The interaction between Stat3 and growth factor receptors was explored with co-immunoprecipitation assays. Results: In HCCLM3 cells, 793 mRNAs were identified as being localized in the Ps fraction according to a cut-off value (Ps/CB ratio) >1.6. The Ps-localized mRNAs could be divided into 4 functional groups, and were all closely related to the invasive and metastatic properties. STAT3 mRNA accumulated in the Ps of HCCLM3 cells compared with non-metastatic SMMC-7721 cells. Treatment of HCCLM3 cells with siRNAs against STAT3 mRNA drastically decreased the cell migration and invasion. Moreover, Ps-localized Stat3 was found to interact with pseudopod-enriched platelet-derived growth factor receptor tyrosine kinase (PDGFRTK) in a growth factor-dependent manner. Conclusion: This study reveals STAT3 mRNA localization at the Ps of metastatic hepatocellular carcinoma HCCLM3 cells by combining application of genome-wide and gene specific description and functional analysis.

    As part of a NASA/DFVLR cooperation program two transonic airfoils were tested in the NASA Langley 0.3-m TCT. Model design and construction was carried out by DFVLR. The models designed and constructed performed extremely well under cryogenic conditions. Essentially no permanent changes in surface quality and geometric dimensions occurred during the tests. The aerodynamic results from the TCT tests which demonstrate the large sensitivity of the airfoil CAST 10-Z/DOAZ to Reynolds number changes compared well with results from other facilities at ambient temperatures.

    Acute coronary syndrome (ACS) is caused by a critical obstruction of a coronary artery because of atherosclerotic coronary artery disease. Three specific conditions are included: ST elevation myocardial infarction, non-ST elevation myocardial infarction, and unstable angina. The ST segment on the electrocardiogram is a sensitive and specific marker of myocardial ischemia and infarction; however, ST segment deviation is regional not global, thus the ECG lead must be placed over the affected region of the myocardium. This article describes ACS and infarction and the use of ST segment monitoring to detect these conditions. PMID:27484662

    The prediction of future space travel in the next millennium starts by examining the past and extrapolating into the far future. Goals for the 21st century include expanded space travel and establishment of permanent manned outposts, and representation of Lunar and Mars outposts as the most immediate future in space. Nuclear stage design/program considerations; launch considerations for manned Mars missions; and far future propulsion schemes are outlined.

    Transcatheter aortic valve implantation is increasingly being used to treat high-risk patients with symptomatic aortic valve disease. However, challenges still remain with current devices, both in terms of the procedure and the outcome. The St Jude Medical Portico transcatheter valve system is designed to mitigate some of these difficulties. We describe the device characteristics and how the device may impact on a TAVI procedure. An overview of the clinical experiences with the Portico valve system is also described. PMID:22995122

    The temperature dependences of the crystal structure and intensities of the (113) and (211) reflections in calcite, CaCO{sub 3}, were studied using Rietveld structure refinements based on synchrotron powder X-ray diffraction data. Calcite transforms from R{bar 3}c to R{bar 3}m at about T{sub c} = 1240 K. A CO{sub 3} group occupies, statistically, two positions with equal frequency in the disordered R{bar 3}m phase, but with unequal frequency in the partially ordered R{bar 3}c phase. One position for the CO{sub 3} group is rotated by 180{sup o} with respect to the other. The unequal occupancy of the two orientations in the partially ordered R{bar 3}c phase is obtained directly from the occupancy factor, x, for the O1 site and gives rise to the order parameter, S = 2x - 1. The a cell parameter shows a negative thermal expansion at low T, followed by a plateau region at higher T, then a steeper contraction towards T{sub c}, where the CO{sub 3} groups disorder in a rapid process. Using a modified Bragg-Williams model, fits were obtained for the order parameter S, and for the intensities of the (113) and (211) reflections.

    Bombesin receptor subtype-3 (BRS-3) is an orphan G-protein-coupled receptor (GPCR) involved in the regulation of energy homeostasis. Mice deficient in BRS-3 develop late-onset mild obesity with metabolic defects, while synthetic agonists activating BRS-3 show antiobesity profiles by inhibiting food intake and increasing metabolic rate in rodent models. The molecular mechanisms and the neural circuits responsible for these effects, however, remain elusive and demand better characterization. We report here a comprehensive mapping of BRS-3 mRNA in the rat and mouse brain through in situ hybridization. Furthermore, to investigate the neurochemical characteristics of the BRS-3-expressing neurons, double in situ hybridization was performed to determine whether BRS-3 colocalizes with other neurotransmitters or neuropeptides. Many, but not all, of the BRS-3-expressing neurons were found to be glutamatergic, while few were found to be cholinergic or GABAergic. BRS-3-containing neurons do not express some of the well-characterized neuropeptides, such as neuropeptide Y (NPY), proopiomelanocortin (POMC), orexin/hypocretin, melanin-concentrating hormone (MCH), thyrotropin-releasing hormone (TRH), gonadotropin-releasing hormone (GnRH), and kisspeptin. Interestingly, BRS-3 mRNA was found to partially colocalize with corticotropin-releasing factor (CRF) and growth hormone-releasing hormone (GHRH), suggesting novel interactions of BRS-3 with stress- and growth-related endocrine systems. Our study provides important information for evaluating BRS-3 as a potential therapeutic target for the treatment of obesity. PMID:22911445

    The heteronuclear metal carbonyl anions MNi(CO)3 (-) (M = Mg, Ca, Al) have been investigated using photoelectron velocity-map imaging spectroscopy. Electron affinities of neutral MNi(CO)3 (M = Mg, Ca, Al) are measured from the photoelectron spectra to be 1.064 ± 0.063, 1.050 ± 0.064, and 1.541 ± 0.040 eV, respectively. The C-O stretching mode in these three clusters is observed and the vibrational frequency is determined to be 2049, 2000, and 2041 cm(-1) for MgNi(CO)3, CaNi(CO)3, and AlNi(CO)3, respectively. Density functional theory calculations are carried out to elucidate the geometric and electronic structures and to aid the experimental assignments. It has been found that three terminal carbonyls are preferentially bonded to the nickel atom in these heterobinuclear nickel carbonyls MNi(CO)3 (-1/0), resulting in the formation of the Ni(CO)3 motif. Ni remains the 18-electron configuration for MgNi(CO)3 and CaNi(CO)3 neutrals, but not for AlNi(CO)3. This is different from the homobinuclear nickel carbonyl Ni-Ni(CO)3 with the involvement of three bridging ligands. Present findings would be helpful for understanding CO adsorption on alloy surfaces. PMID:27036444
