    Waters from the drift deposits and bedrock formations overlying the Hinckley sandstone are hard and calcareous and generally contain troublesome quantities of iron. Regular treatment is required of some public-supply wells for removal of iron encrustations. Water fr.om these sources generally exceeds 300 ppm hardness, but in some places the St. Peter sandstone and St. Lawrence formation yield water of better quality. The Hinckley sandstone yields the best quality ground-water because of its comparatively lower hardness and uniform temperature (about 52 F). However, the average hardness of the treated municipal supplies of St. Paul and Minneapolis is considerably less than water from the Hinckley.

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

    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.

  9. Winter weather and cardiovascular mortality in Minneapolis-St. Paul.

    PubMed

    Baker-Blocker, A

    1982-03-01

    A study of vital statistics data from five Minneapolis-St. Paul winters indicates cardiovascular mortality is influenced by winter temperatures and snow. Although air temperature was not statistically implicated in triggering cardiovascular mortality in four of the five study winters, during the winter of 1976-77, about 15 per cent of the variance in daily cardiovascular mortality could be attributed to fluctuations in the daily minimum air temperature. Snow influenced mortality on the day of occurrence as well as the two days following a snowfall. There appear to be some differences in the ability of winter weather to influence mortality from acute myocardial infarction (ICD 410) and old myocardial infarction (ICD 412). The variance in daily ICD 410 mortality attributable to the influence of snow is somewhat less than that in daily ICD 412 mortality. The greatest variance in daily ICD 412 mortality that could be ascribed to snow occurred during the winter of 1974-75, and was 13 per cent. It is likely that rain intermixed with snow may also trigger increased mortality from cardiovascular disease. A combination of rain and snow can produce dramatic increased in mortality from ICD 410. Study of mortality data from five winters indicates that snow is somewhat more important in triggering deaths from heart disease than is air temperature.

  13. Climatology of Diffusion Potential Classes for Minneapolis-St. Paul.

    1997-12-01

    This climatological study reports on the potential for atmospheric diffusion at Minneapolis-St. Paul, Minnesota, cities located in the heart of the North American continent. As such, the results can be considered typical of an urban setting within a continental climate.Data were obtained from a nearly continuous 8-yr record of vertical temperature and wind measurements made on a 152.4-m tower. Temperature lapse rates between 21.3 and 152.4 m were grouped into three stability categories: 1) isothermal-inversion, 2) subadiabatic, and 3) superadiabatic. A subdivision of each was based upon wind speeds of less than 4 m s1 and greater than or equal to 4 m s1, resulting in six classes that were examined according to wind direction, time of day, time of year and, most importantly, the associated synoptic conditions.The isothermal-inversion condition was limited to nighttime periods, especially when high pressure centers were dominant and winds were less than 4 m s1. The highest frequency of occurrence was during midsummer, while the lowest was during late fall and early winter. The subadiabatic condition was primarily a nighttime phenomenon, except for the winter season when it was also common during the day. An interesting feature of the diurnal frequencies was that a morning and evening subadiabatic peak occurred due to the transition between nighttime stable and the daytime unstable conditions. The superadiabatic condition was mainly a daytime phenomenon and dominated the early afternoon period throughout the year.The lowest diffusion potential, a result of very stable air and light winds, occurred during the nighttime period, particularly when under the influence of a high pressure center. Weak to moderate diffusion potential, found to occur with weakly stable air and light to moderate winds, was associated with the perimeter of the high pressure center and also with overcast skies near a low pressure center. This condition normally occurred during the night as well

    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.

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

    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.

    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.

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.

    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

    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

  13. The use of GIS for monitoring and predicting urban growth in east and west St Paul, Winnipeg, Manitoba, Canada.

    2002-11-01

    Most urban growth in Canada occurs in the urban-rural fringe. The increasing dispersal of the Canadian urban population is due to centrifugal forces pulling urbanites past the suburbs into the surrounding exurban communities. Most Canadian urban centres are located on prime agricultural land. Exurban sprawl devours an inordinate amount of the better agricultural land. The growth around the city of Winnipeg is a case in point. Within Winnipeg's urban field are the rural municipalities of East and West St Paul. The objective of this study is to investigate the impact of urban growth on the agricultural land of these RMs as well as the rate of urban growth in both Municipalities based on database analysis using aerial photographs taken in 1960 and 1989 and Geographic Information System (GIS). East St Paul was found to have a higher rate of urbanization (from 10.14% to 43.75%) between 1960 and 1989 than West St Paul (from 7.36% to 23.57%). The growth prediction using Markov probability chain analysis showed that East St Paul will henceforth experience a reduced rate of increase than West St Paul. The rate of urbanization for both RMs is found to be comparable with areas surrounding other major cities such as Toronto. The largest increases in urban land use categories occurred in and around the existing exurban settlements. It was found that most urbanization take place on the most fertile soil.

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)

    The decline in the number of northern fur seal (NFS; Callorhinus ursinus) pups on St. Paul Island, Alaska, has led to multidisciplinary research, including investigation into issues of reproductive health and success. Given the recent identification of Coxiella burnetii in the placenta of two other marine mammal species, NFS placentas were collected from Reef rookery on St. Paul Island, Alaska, during the 2010 pupping season, examined histologically, and tested for C. burnetii using polymerase chain reaction (PCR). Of 146 placentas examined, gram-negative intratrophoblastic bacteria that were positive for C. burnetii on immunohistochemistry were observed in 5 (3%) placentas. Placental infection was usually devoid of associated inflammation or significant ancillary pathology. One hundred nine (75%) of the placentas were positive for C. burnetii on PCR. C. burnetii is globally distributed and persists for long periods in the environment, providing ample opportunity for exposure of many species. The significance of this finding for the declining fur seal population, potential human exposure and infection, and impact on other sympatric marine mammal or terrestrial species is unclear; further investigation into the epidemiology of Coxiella in the marine ecosystem is warranted.

    An in vitro comparison of centrifugal pumping systems manufactured by Sarns-3M and St. Jude Medical revealed a difference in blood cell derangement. The purpose of this study was to compare in vivo the effects of 96 hr of left ventricular assist (LVA) on indexes of coagulopathy, hemolysis, and complement activation. Two groups of calves (each: n = 5) were instrumented with identical left atrial to thoracic aorta centrifugal pumping circuits using either Sarns-3M or St. Jude centrifugal pumps. Laboratory evaluations were performed pre-assist and at 1, 4, 24, 48, 72, and 96 hr during LVA. Platelet counts dropped significantly by 24 hr (Sarns-3M: 28%; St. Jude: 30%); no significant change in function was noted. Activated clotting time increased slightly (p > 0.05). Prothrombin time increased at 4 and 24 hr of LVA, returning to baseline by 96 hr (p < 0.05). Activated partial thromboplastin time increased with the St. Jude device from 24 to 96 hr on LVA (p < 0.05); the increase with the Sarns-3M device never reached significance. No significant changes in lactate dehydrogenase or plasma free hemoglobin were detected. Complement fraction C5a rose by 1 hr of LVA (p < 0.05), peaking at 4 hr and returning to baseline by 96 hr with both pumps. No significant difference was detected between pump groups for any of the parameters. It was concluded that 1) 96 hr Sarns-3M and St. Jude LVA caused coagulation derangement in calves, 2) neither pump demonstrated an advantage regarding coagulation and complement parameters, 3) hemolysis observed with the Sarns-3M pump in vitro was not evidenced in vivo, and 4) in vitro evidenced centrifugal pump differences may not be realized in vivo.

  17. Persistence rates and detection probabilities of oiled king eider carcasses on St Paul Island, Alaska

    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.

  4. PM10, ozone, and hospital admissions for the elderly in Minneapolis-St. Paul, Minnesota.

    Schwartz, J

    1994-01-01

    Several recent studies have reported associations between airborne particles and/or ozone and hospital admissions for respiratory disease. PM10 has rarely been used as the particle exposure measure, however. This study examined whether such an association could be seen in Minneapolis-St. Paul, Minnesota, which has daily monitoring data for PM10. Data on hospital admissions in persons aged 65 y and older were obtained from Medicare records for the years 1986 through 1989. Daily counts of admissions, by admit date, were computed for pneumonia (ICD9 480-487) and chronic obstructive pulmonary disease (COPD) (ICD9 490-496). Classification was by discharge diagnosis. Daily air pollution data from all monitoring stations for ozone and PM10 in Minneapolis-St. Paul were obtained, and the daily average for each pollutant was computed. An average of approximately six pneumonia admissions and two admissions for chronic obstructive pulmonary disease occurred each day. Poisson regression analysis was used to control for time trends, seasonal fluctuations, and weather. PM10 was a risk factor for pneumonia admissions (relative risk [RR] = 1.17, 95% confidence interval [CI] = 1.33-1.02) and COPD admissions (RR = 1.57, 95% CI = 2.06-1.20). Ozone was also associated with pneumonia admissions (RR = 1.15, 95% CI = 1.36-0.97). The relative risks are for an increase of 100 micrograms/m3 in daily PM10 and 50 ppb in daily ozone concentration. Several alternative methods for controlling for seasonal patterns and weather were used, including nonparametric regression techniques. The results were not sensitive to the methods. When days exceeding the National Ambient Air Quality Standard for either pollutant were excluded, the association remained for both pneumonia (RR = 1.18, 95% CI = 1.34-1.03 for PM10, and RR = 1.18, 95% CI = 1.41-0.99 for ozone) and COPD (RR = 1.54, 95% CI = 2.06-1.16 for PM10).

    The diversity and ecology of cestodes from the northern fur seals, Callorhinus ursinus (NFS), were examined using newly collected material from 756 humanely harvested subadult males between 2011 and 2014. NFSs were collected from five different haul-outs on St. Paul Island, Alaska. A total of 14,660 tapeworms were collected with a prevalence of 98.5% and intensity up to 107 cestodes per host (mean intensity 19.7 ± 16.5 SD). Three species of tapeworms were found: Adenocephalus pacificus (Diphyllobothriidea) was the most prevalent (prevalence 97.4%), followed by Diplogonoporus tetrapterus (49.7%), and 5 immature specimens of Anophryocephalus cf. ochotensis (Tetrabothriidea) (0.5%). Most of the cestodes found in the NFS were immature (69.7%). However, only 0.9% of cestodes were in larval (plerocercoid) stages. The species composition, prevalence and intensity of cestodes from these NFSs were not statistically different between the five separate haul-outs. Significant increases in the intensity of NFS infections were observed during the study period. PMID:26101743

    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

    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.

    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.

    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.

    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.

    Microorganisms must migrate in order to maintain position with respect to geochemical gradients, and many exhibit tactic behavior to optimize their position. However, certain microorganisms in subsurface environments form persistent attachments to solid particles or are non-motile, leading to the differential burial of a subset of active cells (i.e. what is preserved may differ from what is—or was—active at a given horizon). Deep sedimentary horizons may inherit a microbial community that fails to maintain its optimum position with respect to geochemical profiles. Few studies have attempted to constrain how changes in sediment accumulation or lithology impact microbial diversity and abundance. Oligomictic Lake McCarrons and meromictic Brownie Lake, both located within the Minneapolis-St. Paul, MN metropolitan area, represent the impact of urban runoff and land use changes leading to eutrophication and bottom water anoxia over the past century. Previous studies have exhibited a rich historical record in the lake sediments, with significant lithological transitions linked to human activity and efforts to mitigate long-term internal phosphorus loading. In July, 2012, freeze cores were collected from the top ~1m of sediment beneath the deepest, oxygen-depleted waters of each lake in order to characterize the 16S rRNA gene diversity of microbial communities present in distinct lithological horizons as well as the extent of community signature transgression across sedimentary boundary layers. A ~5cm horizon of amorphous aluminum hydroxide resulting from a 2004 Lake McCarrons alum (aluminum sulfate) treatment was selected for high-resolution study as well as the layers corresponding to the ~1925 Brownie Lake transition to bottom water anoxia. Terminal Restriction Fragment Length Polymorphism (T-RFLP) profiles referencing amplicon sequence libraries generated from select horizons provide constraints on vertical migration of microbial communities in response to

    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

    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.

  5. 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.

    Prevalence of hookworms (Uncinaria lucasi Stiles, 1901) was determined in the northern fur seal (Callorhinus ursinus Linnaeus, 1758) on St. Paul Island (SPI), Alaska in July and August, 2011. Three of 61 (4.9%) dead pups harbored 1 to 13 adult hookworms each in their intestines. Parasitic larvae (L(3)) of hookworms were recovered from the blubber of 4 of 133 (3%) of subadult males (SAMs) examined. One parasitic L(3) was detected from each infected SAM. Adult U. lucasi (n = 3) were found in the intestine of 1 of 105 SAMs examined (0.95%). This is the first documented finding of adult U. lucasi in SAMs of the northern fur seals. Continued low prevalence of hookworms the last several years parallels the tremendous decline in the number of fur seals on SPI over a similar time period.

    Monitoring studies of acanthocephalans in northern fur seals (Callorhinus ursinus Linnaeus, 1758) (NFSs) and a harbor seal (Phoca vitulina Linnaeus, 1758) were performed on St. Paul Island, Alaska, in July-August 2011. Gastrointestinal tracts of 105 humanely harvested NFS subadult males (SAMs) (3-4 years old) were collected during the annual Aleut subsistence harvest at four haul-out areas (HOAS): Lukanin (n = 26 NFSs), Polovina (n = 28), Gorbatch (n = 30), and Morzhovyi (n = 21). One gastrointestinal tract collected from a harbor seal (about 3-4 years old) found dead at Morzhovyi HOAS was also examined. The total prevalence of infection in NFSs with acanthocephalans was 29.52 % with variations from 7.69 % to 47.62 % between the four different HOAS. Eight acanthocephalan species of two genera-Corynosoma Lühe, 1904 (Corynosoma strumosum, Corynosoma alaskensis, Corynosoma cameroni, Corynosoma semerme, Corynosoma similis, Corynosoma validum, and Corynosoma villosum), and Bolbosoma Porta, 1908 (Bolbosoma nipponicum)-were found in the NFSs and a harbor seal. This is a new record of C. alaskensis for the NFSs. Short biological notes of the species found are presented. Differences in species composition as well as in prevalence of acanthocephalans parasitizing NFSs were observed in subpopulations from four different HOAS on St. Paul Island. The highest biodiversity of acanthocephalans and infection were found in subpopulations on Polovina and Morzhovyj HOAS, the lowest was on Lukanin HOAS. From 3.2 % (for C. validum) to 19.4 % (for C. villosum) of NFSs were infected by one acanthocephalan species; two species were found in 22.6 %; three in 9.7 %; and four in 3.2 %. Further studies of NFS parasites are necessary to follow the trends in parasitic infection rates and diversity in NFS population on the Pribilov Islands and for monitoring the influence of various ecological factors on NFS populations in Alaska.

    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.

    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

    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.

    Mean and median daily albedos of the November-April period are presented for a nonforested station in the North Central region of the United States where frozen soil and persistent snow cover are common winter features. Three distinct albedo periods were found, the occurrence of which can be explained by comparison with associated daily records of air temperature and snow depth. These periods are: I) Introduction to Winter, 9-22 November, a transitional period in which snowfalls begin to occur but with insufficient frequency or duration to greatly alter the mean albedo from growing season values; II) the High Albedo Season, 23 November-17 March, that is characterized by mean and median albedos of 50% or higher and by a negatively skewed distribution of albedo values in contrast to periods I and III; and III) the transition period, Introduction to Spring, 18 March-12 April, where late season snowfalls of brief duration occur, but the mean albedo is lower than in period I because of the more common occurrence of moist surfaces due to snowmelt and rains.

    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

  1. Paul Gauguin in Brittany

    NASA Astrophysics Data System (ADS)

    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.

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

    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.

    During his three stays in psychiatric institutions between 1884 and 1911, Daniel Paul Schreber was also twice treated in the psychiatric and neurological hospital of Leipzig University headed by Paul Flechsig. In his "Memoirs of a Nervous Patient," Schreber also described the treatment he had received there, which in his perception seemed to be of crucial importance for his later fate. Research on the Schreber case in the last 25 years, based mainly on the interpretation of his own memoirs, supported the view that in fact Flechsig was to blame to a great extent for the outbreak of Schreber's paranoid schizophrenia in February 1894. This paper aims at forwarding exonerating arguments in favor of Flechsig, concluding that what he did did not differ distinctively from the standard tenets of organic psychiatry taught at that time. Of course this does not change the fact that Schreber did not receive the right kind of treatment. However, it puts Flechsig's approach into the right perspective.

    1999-02-01

    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.

  12. Paul of Aegina: landmark in surgical progress.

    PubMed

    2003-01-01

    During the Byzantine period the most prominent medical personalities were Oribasius, Aetius of Amida, Alexander of Tralles, and Paul of Aegina (Paulus Aegineta). The last of the eclectic Greek compilers, Paul of Aegina (625-690 AD) was born on the island of Aegina and practiced medicine in Alexandria. He was the author of the Epitome of Medicine (seven books), which was first printed in Greek by the Aldine Press in Venice in 1528. The Syndenham Society of London published an English translation by Francis Adams of Banchory between 1844 and 1847. The most noteworthy of his Epitome is the sixth book on surgery. Paul was not only a scribe but also a highly capable surgeon. He was the quintessential student of the best medical authorities: Hippocrates and Galen in Greek and Roman medicine, respectively. He also displayed a peculiar genius in the field of surgery. He gave us novel descriptions of tracheotomy, tonsillectomy, catheterization of the bladder, lithotomy, inguinal hernia repair, abdominal paracentesis for ascites, and many other surgical procedures including reduction of breast size. He not only influenced those in his own era but had great influence on physicians such as Rhazes, Haly Abbas, Albucasis, Avicenna, and Fabricius ab Aquapendente, who lived in subsequent eras. This historical article emphasizes the role of Paul of Aegina in the history of surgery and provides a comprehensive review of his surgical treatise with original case examples that represent his contributions to surgical progress.

    2007-12-01

    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.

    2011-04-19

    An array of microfabricated linear Paul-Straubel ion traps can be used for mass spectrometric applications. Each ion trap comprises two parallel inner RF electrodes and two parallel outer DC control electrodes symmetric about a central trap axis and suspended over an opening in a substrate. Neighboring ion traps in the array can share a common outer DC control electrode. The ions confined transversely by an RF quadrupole electric field potential well on the ion trap axis. The array can trap a wide array of ions.

    Paul Sudeck is not generally recognised as a pioneer in anaesthesia, although he is well known for the atrophy of bone named after him. However, he not only championed the use of ether as a safe anaesthetic agent, described a method of ether analgesia for outpatient surgery and devised an inhaler for its administration, but also reintroduced nitrous oxide into Germany and invented possibly the first circle carbon dioxide absorption system with an optional attachment for continuous positive pressure respiration useful for the performance of thoracotomies.

    In 1892-93, Paul Ehrlich published a series of experiments on the passive transfer of maternal antibody to fetus and newborn that deserve to be better known. He pointed out the importance of mother's milk to neonatal well-being. He was the first to define the difference between active and passive immunity. He was the first to demonstrate immune elimination of antigen and to explain the significance of each phase of the kinetics of the anamnestic antibody response. We point out how elegant were these early experiments and how far in advance of their times.

  19. 3M's PPR software criticized, but is research misleading?

    PubMed

    2015-12-01

    New research suggests that a popular 3M software program doesn't clearly distinguish differences in care quality. The issue is important because the program is increasingly used to make payments to U.S. hospitals based on readmission rates. 3M says the study is flawed and the conclusion incorrect. The researchers concluded that either PPR flagged cases are not more preventable, or additional data collection is needed. The findings are based on a review of 100 randomly selected cases.

    1994-07-01

    A search via databases and indexes, as well as the American Dental Association package library collection, yielded no evidence of participation by American dentists in outboard motor or hydroplane inboard motor boat racing. There may be or have been such participants, but the contributions of Paul Sheppard Burnham, DDS are noteworthy and quite probably unique. Competing always as an amateur, his racing ability was respected; on many occasions he outraced professional drivers. Dr. Burnham led an interesting life. In his 83 years, he operated and soon thereafter traded automobile after automobile (a total of 49)--satisfying his love for fast and unusual cars. While practicing dentistry most of his adult life, he managed to become an integral part of the Rehoboth Beach, DE beach patrol, serving for ten years as captain of lifeguards and, in a few of his senior years, as chief. As the 20th century comes to a close, a good deal is written and spoken about those identified as unusual, vibrant, daring, spirited, competitive, self-confident, and colorful--travelers in the fast lane. Paul S. Burnham, DDS spent a great part of his life in the fast lane, with very few in front of him. PMID:7987052

  1. k and q Dedicated to Paul Callaghan

    NASA Astrophysics Data System (ADS)

    Blümich, Bernhard

    2016-06-01

    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.

  4. 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.

  6. 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

  10. 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.

  11. 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.

    2010-10-01

    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.

  13. 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.

  14. 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.

  15. Open letter to Pope John Paul II.

    PubMed

    Sai, F

    1991-01-01

    In an Open Letter to Pope John Paul II, written on World Population Day (July 11) 1991, Dr. Fred Sai, President of International Planned Parenthood Federation (IPPF), called for a dialogue on voluntary family planning as a means of avoiding unwanted pregnancy. A half million women die each year from pregnancy-related causes--a death toll that could be dramatically reduced by universal access to low cost, effective contraception. Family planning further represents the best protection against abortion. The Catholic Church's vehement opposition to abortion and family planning methods other than periodic abstinence is in marked contrast to its support to human rights in other settings. The Church has supported struggles for economic ju stice in and among nations, sided with the poor, and advocated for transitions to democracy. At the same time, the family planning movement--which has as its overall objective the protection of the health and welfare of women, children, and families--is viewed by the Vatican as a vehicle for the enslavement rather than liberation of women. The opening of a sensitive dialogue between the Catholic Church and supporters of voluntary family planning could help couples make sound moral decisions about their families and contribute to saving the lives of millions of women, most of them poor.

    In 2004, we celebrate the 150th anniversary of the birth of Paul Ehrlich, considered the founder of immunology. His life and work can be divided into three creative periods: first, he developed histological staining, then he accomplished his ground-breaking work on immunology, and eventually invented chemotherapy. Paul Ehrlich can be perceived as a man whose success was not the consequence of a will to power, but of his substantial interest in science.

    1980-01-01

    A 3 m diameter model of a two bladed Musgrove vertical axis windmill has been tested in the British Aerospace wind tunnel at Filton. Tunnel constraints were kept to a minimum by using a low flow blockage and appropriate corrections were applied to the measurements. The results of these tests demonstrate the good performance of this type of windmill. Comparison of the measured performance with predictions from a simple mathematical model show excellent agreement. Maximum loads measured on the windmill are not well predicted by the mathematical model. In order to reconcile measurement and prediction large induced crossflows must be postulated at some blade rotational positions.

    The 3M vanpooling program is examined to find out why it has been successful while carpooling has declined. Employee surveys are used to determine which incentives and disincentives are in effect and which psychological factors are important. Analysis of six factors (personal freedom restriction, longevity, auto ownership and competition, travel cost, interpersonnal relationships, and distance from home to work) is used to break down the survey information and establish the attitudes which determine behavior. The findings can be used to reduce or eliminate most of the objections to carpooling and to emphasize the positive aspects. A personalized matching program is also recommended. 1 figure, 5 tables.

    Results of an experimental study of geodesic acoustic modes (GAM) in the TUMAN-3M tokamak are reported. 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.

  19. 30 years of ergonomics at 3M: a case study.

    PubMed

    Larson, N; Wick, H

    2012-01-01

    The added value of the Ergonomics Program at 3M was found to be improved employee safety, compliance with regulations and reduction of work-related illness, increases in productivity, and quality and operating efficiency. This paper describes the thirty years of existence of this program. For the first twenty years, the program objectives were to: respond to requests for assistance related to work-related musculoskeletal disorder (WMSD) concerns, raise employee awareness of MSDs and ergonomics; educate engineers in ergonomics design; and develop ergonomics teams at manufacturing locations. Since the year 2000, 3M's Ergonomics Program has been in transition from a US-centric and corporate-based technical-expertled program to a global program applying participatory ergonomics strategies within a macroergonomics framework. During that transition, the existing program requirements were revised, new methods and program tools were created, and expectations for implementation at the manufacturing locations clarified. This paper focuses on the company's manufacturing ergonomics program activities during the past ten years and includes specifics of the program's objectives, risk assessment reduction process, and ergonomics technical expertise development. The main benefit achieved throughout the company is reducing employee injury while also increasing productivity and operating efficiency.

    Intrauterine growth retardation is caused by maternal, fetal or placental factors that result in impaired endovascular trophoblast invasion and reduced placental perfusion. Although various causes of intrauterine growth retardation have been identified, most cases remain unexplained. Studying 29 families with 3-M syndrome (OMIM 273750), an autosomal recessive condition characterized by severe pre- and postnatal growth retardation, we first mapped the underlying gene to chromosome 6p21.1 and then identified 25 distinct mutations in the gene cullin 7 (CUL7). CUL7 assembles an E3 ubiquitin ligase complex containing Skp1, Fbx29 (also called Fbw8) and ROC1 and promotes ubiquitination. Using deletion analysis, we found that CUL7 uses its central region to interact with the Skp1-Fbx29 heterodimer. Functional studies indicated that the 3-M-associated CUL7 nonsense and missense mutations R1445X and H1464P, respectively, render CUL7 deficient in recruiting ROC1. These results suggest that impaired ubiquitination may have a role in the pathogenesis of intrauterine growth retardation in humans.

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

    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. The model provided a best-fit analysis regarding the likely contributions of each source to the sample results. The results of these evaluations lead to the conclusion that the current emissions from this Facility do not present an unacceptable risk to human health.

  4. Testing of the 3M Company ACCR Conductor

    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

    2005-12-01

    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

    The life and career of the great French mathematician and politician Paul Painlevé is described. His contribution to the analytical theory of nonlinear differential equations was significant. The paper outlines the achievements of Paul Painlevé and his students in the investigation of an interesting class of nonlinear second-order equations and new equations defining a completely new class of special functions, now called the Painlevé transcendents. The contribution of Paul Painlevé to the study of algebraic nonintegrability of the N-body problem, his remarkable observations in mechanics, in particular, paradoxes arising in the dynamics of systems with friction, his attempt to create the axiomatics of mechanics and his contribution to gravitation theory are discussed.

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

    PubMed

    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

    2012-02-01

    Leprosy and diabetes, though two very different conditions, may both result in severe loss of sensation in the feet, which are then a great risk of painless injury and ulceration. Seminal observations made by the late Dr Paul W. Brand, a surgeon working with leprosy patients in South India in the mid-20th century, resulted in the subsequent development of treatments to manage insensitive foot ulcers that are today entirely applicable to patients with diabetes. As a consequence of his research, the recognition of the relationship between insensitivity, repetitive pressures and skin breakdown has helped our understanding of the aetiopathogenesis of neuropathic foot lesions in diabetes: the development of the total contact cast and other casting devices to treat such lesions forms the basis of management of diabetic foot lesions with off-loading devices that are widely used in the 21st century in diabetic foot clinics around the world. Moreover, observations by Brand that the foot 'heats up before it breaks down' resulted in more recent research showing that self-skin temperature monitoring might help reduce the incidence of recurrent neuropathic foot ulcers in diabetes. In summary, Brand's understanding of 'the gift of pain' that, when lost, results in the late complications of diabetic neuropathy has guided the prevention, diagnosis and management of diabetic foot problems in the 21st century.

  14. 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

  17. The St. Petersburg paradox: An experimental solution

    NASA Astrophysics Data System (ADS)

    Da Silva, Sergio; Matsushita, Raul

    2016-03-01

    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.

  18. Paul Klee's illness (systemic sclerosis) and artistic transfiguration.

    PubMed

    Suter, Hans

    2010-01-01

    Klee's symptoms, and the rapid progression of the illness, ending with his death after only 5 years, in all probability indicate the rarest but most serious form of scleroderma, known as diffuse systemic sclerosis. Although his skin and internal organs were heavily stricken by the illness, the artist's hands were fortunately spared. Thus he was able to draw and paint without hindrance to the end. Classified amongst diseases of the autoimmunity system, this form of sclerosis often has inexplicable causes. I believe, however, that the defamations suffered by Klee, his dismissal as professor of the Art Academy in Düsseldorf by the National Socialists, and the unintended isolation after his return to Berne were causative factors in the outbreak of the illness. Mentally and spiritually, the artist rose above his heavy bodily suffering. Constantly, his creativity remained vigorous. Although the greater part of Klee's works in his last years cannot be linked directly with his illness, careful viewing reveals a significant preoccupation with fate and illness. It is above all in his drawings, that were created like a diary, that the sorrows and troubles of the ill artist emerge: his fears, but also his hopes and finally his resignation to the illness, and his readiness for death. In undesired isolation, and in his own spiritual world, Paul Klee created with exemplary concentration, discipline and diligence a considerable number of late works, which differ from his early work and which deserve our full admiration. Reserved, quiet and kind, Paul Klee was nevertheless charismatic. And his art is poetic. Possessing a special aura, it can enchant those who surrender to it without any prejudice. Paul Klee has created an oeuvre that is unique, reflecting his character closely: a body of work that moves and stirs us by its deep humanity.

    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.

    We wish to commemorate Paul Ehrlich on the centennial of his being awarded the Nobel Prize in Physiology or Medicine in 1908. His studies are now considered as milestones in immunology: the morphology of leukocytes; his side-chain theory where he defined the cellular receptor for first time; and his clarification of the difference between serum therapy and chemotherapy. Ehrlich also invented the first chemotherapeutic drug: compound 606, or Salvarsan. We have used some original documents from the Royal Society of London, where Ehrlich was a fellow, and from Leipzig University, where he took a degree in medicine.

  5. 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

    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.

    From his student days throughout his whole life, Paul Ehrlich tried hard to obtain 'chemotherapia specifica' for the harmless systemic therapy of infectious diseases. Given the poor therapeutic benefit obtained with cytotoxic therapeutic agents and empirical radiopharmaceuticals, so far used only for neoadjuvant and adjuvant treatments of cancer, we have tried to develop Paul Ehrlich's 'chemotherapia specifica' for safe and effective therapy of cancers in cigarette smokers. With the help of sector-field inductively coupled plasma mass spectrometry, we have tried to find the metabolic action of cigarette smoke constituents in the cancerous organ. On the basis of these results we are synthesizing pharmaceuticals and radiopharmaceuticals to purge the tobacco-constituent metabolic products that cause cancer. The purity, stability and chemical nature of the pharmaceuticals and radiopharmaceuticals required for therapy have been studied by chromatography and electrophoresis. The cancer specificity of the therapeutic agent has been examined by the total body distribution of its gamma- and beta-labelled species in solution. At present, a bladder cancer-specific therapeutic agent is being developed.

  8. Decreased relative expression level of trefoil factor 3 mRNA to galectin-3 mRNA distinguishes thyroid follicular carcinoma from adenoma.

    The expression level of trefoil factor 3 (TFF3) mRNA is a marker for distinguishing thyroid follicular adenomas from carcinomas. However, when measuring the expression level of TFF3 mRNA in fine needle aspiration biopsies, an appropriate internal control mRNA, of which expression is restricted in thyroid epithelial--derived cells, is necessary, since they are often contaminated with a considerable number of blood cells, which do not express TFF3 mRNA. In this study, we evaluated the efficiency of molecular-based diagnosis of thyroid follicular carcinoma by measuring the relative expression of TFF3 mRNA by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) using galectin-3 mRNA as an internal control. The TFF3/galectin-3 mRNA ratio (T/G ratio) was measured in 54 follicular adenomas and 29 follicular carcinomas. It was markedly decreased in 7 follicular carcinomas of widely invasive type and with evident distant metastases. When the cutoff point was set at 16.0 by a receiver operator characteristic curve, the TG ratio showed good agreement with the pathological diagnosis [kappa=0.55; 95% confidence interval (CI), 0.34-0.77]. This agreement was better when the pathologically questionable cases were excluded (kappa=0.72; 95% CI, 0.49-0.95). Quantification of the T/G ratio may be a useful tool for the distinction between follicular adenomas and carcinomas, which is the most difficult in thyroid pathology.

    The German writerJean Paul (Johann Paul Friedrich Richter, 1763-1825) and his friendJohann Bernhard Hermann (1761-1790) became acquainted with the thoughts of late Enlightenment at the University of Leipzig. They particularly appreciated the anthropology of Ernst Platner, who taught philosophy and aesthetics as well as medicine. Their confidential correspondence contains reflections on their respective situation and well being. Both write about feeling ill and label their illness "hypochondria". In the course of the correspondence Jean Paul's understanding of hypochondria evolves from an illness of the entrails as he follows Hermann, who supports the modern concept of hypochondria as an illness of the nerves. Two important themes from this correspondence recur in Jean Paul's novels and tales: firstly, his way of expressing comfort is related to his aesthetics, and secondly, the satirical way of portraying at least certain aspects of illness as imaginary reappears in his first successful novel "The Invisible Lodge" (1793).

    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.

  17. 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.

    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.

    1995-12-01

    In a meta-diagnostic evaluation of Daniel Paul Schreber's (1840-1911) case history the conclusion is that he suffered from an anxiety-blissfulness psychosis. This results from a comparison of Schreber's autobiographical remarks as published in his "Memoirs" on the one hand with his psychiatrist's remarks in his clinical files on the other. The main characteristics of his illness were extensive anxieties and ecstatic elation. Since Schreber's book in recent years has been published in English, French and Italian translations and a number of biographical details have surfaced, a new international discussion has developed. The Schreber case partly is being seen as prototype of schizophrenia, partly as the typical result of the drill of a father education. Both views can be refuted out of the available material. This paper concentrates exclusively on the clinical diagnostic question.

    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.

    2016-01-01

    Paul Broca surmised that the short and broad-brachycephalic-skulls of the earliest European settlers had become longer and narrower-dolichocephalic-in modern populations due to the blending of different races. Swedish anatomist Anders Retzius had two brachycephalic skulls said to be from contemporary Basque individuals, a claim suited to test Broca's hypothesis. Broca worked with fellow anatomist and surgeon Pedro González Velasco, the founding father of Spanish anthropology, to gather a large number of Basque skulls. In its time, this was the most fascinating collection owned by the Anthropological Society of Paris. This article explains how Broca and Velasco were able to gather such a sizeable array of specimens, which they had collected at a location known at first by the code name of "Z." Although Broca finally concluded that the origin of the Retzius skulls could not be determined, his research was to spark anthropologists' interest in the language and origins of the Basque people.

    The history of the external as well as the internal photoeffects in solids is closely connected with the development of quantum-mechanical foundation of electronic states in solids and of interaction of light with matter. Paul Goerlich entered science with the invention of the cesium antimonide photocathode in 1936. Combining the experience of early semiconductor physics in Germany with the feeling of an industrial manager for maturity of results for application in measurement, Goerlich became an active promoter of the physics of photoeffects both as an author and as an active member of IMEKO. The state-of-the-art of the photoeffect physics at the time when Goerlich began his career, when he was active as a teacher and editor as well as after that time, will be outlined. Typical concepts will be ordered into the scientific and technological context. The exciting new possibilities of artificial microstructures will open new applications.

    2001-10-01

    The present study investigates the molecular basis of the G3m polymorphism expressed by the heavy constant domains of human immunoglobulins gamma 3 chains. By using a new protocol allowing the specific cloning of IGHG3 genes, a total of 51 full-length IGHG3 genomic sequences (about 2 kb) isolated from African, Siberian, West Asian and European population samples were sequenced. IGHG3 sequences were assigned precise G3m haplotypes on the basis of specific associations between G3m allotypes and IGHG3 RFLPs. Specific DNA substitutions involved in the expression of G3m(5), G3m(6), G3m(15), G3m(16), G3m(21), G3m(24) and G3m(28) allotypes were then deduced, elucidating almost completely the determination of the G3m polymorphism at the DNA level. The molecular evolution of G3m haplotypes was investigated by a maximum likelihood phylogeny of IGHG3 sequences. Sequence clusters are shown to be G3m haplotype-specific, corroborating the Gm molecular model deduced from serology, and showing that populations differentiation is much more recent than G3m haplotypes differentiation. The widely distributed G3m(5,10,11,13,14) haplotype is likely to be ancestral to the other G3m haplotypes presently found at high frequencies in different continental areas.

    On July 9, 1940, asylum director Paul Braune completed a twelve-page memorandum, or Denkschrift, on the National Socialists' T-4 "euthanasia" program. The memorandum identified three killing centers within a carefully planned, Reich-wide program and summarized what Braune's research had uncovered about the fate of asylum patients at various T-4 facilities. Braune estimated that several thousand disabled people had been murdered between February and June 1940. After Protestant church leaders formally submitted Braune's memorandum to the Reich Chancellery, Braune was arrested by the Gestapo-pursuant to a direct order by Reinhard Heydrich-for having "sabotaged measures of the state in an irresponsible way." Despite Braune's protest, the killing of German asylum patients continued unabated. This article shows what a determined German citizen, assisted by an extensive network of information sources, was able to learn about the "euthanasia" program during the first six months of its implementation, and reveals the formidable difficulties that opponents of the program faced in their efforts to stop the killing of disabled people.

  16. 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.

    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.

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."

    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).

    Paul Ehrlich (1854-1915) is nowadays considered a pioneer in a number of medical fields, and in the course of time his role in the establishment and development of disciplines such as histology, immunology, oncology and haematology has been acknowledged. Aim of this historical note is to illustrate, in the area of chemotherapy, the special importance of this brilliant scientist whose 150th anniversary of birth occurred in 2004. Already as a medical student, Ehrlich was obsessed by structural organic chemistry and dyes, and, continually studying these issues, he elaborated his theory regarding the discovery of a "magic bullet", able to specifically destroy tumour cells and micro-organisms. In practice he applied methylene blue to the treatment of malaria patients, following his intuition that such a dye could destroy parasites. However, his culminating achievements in the chemotherapic field, reached even at the expense of his health, were the concept of the one-dose treatment of Helicobacter pylori infection, and the creation of arsphenamine (compound 606, or Salvarsan), the first really effective compound in controlling human syphilis. Within the many and various contributions of Ehrlich to the development of experimental and clinical medicine, a special mention of his experimental studies and clinical applications in the area of chemotherapy is essential, since his achievements in this biomedical area remain a paramount legacy in the history of the therapy of infections.

    The effect of resonance crossing on beam stability is studied systematically by employing a novel tabletop experimental tool and a multiparticle simulation code. A large number of ions are confined in a compact linear Paul trap to reproduce the collective beam behavior. We can prove that the ion plasma in the trap is physically equivalent to a charged-particle beam propagating through a strong focusing channel. The plasma confinement force is quickly ramped such that the trap operating point traverses linear and nonlinear resonance stop bands. Assuming a nonscaling fixed field alternating gradient accelerator composed of many identical FODO cells, we measure how much ion losses occur under diverse conditions. It is experimentally and numerically demonstrated that too slow resonance crossing leads to significant ion losses as expected. Particular attention must be paid to the linear coherent resonance excited at a quarter-integer tune. When the beam intensity is high, this type of linear stop band can seriously affect the beam quality even for rather fast resonance crossing. A scaling law is given of the emittance growth caused by the quarter-integer resonance crossing.

    The Paul do Boquilobo is an important wetland ecosystem classified by Unesco as a MAB Biosphere reserve also awarded Ramsar site status, representing one of the most important habitats for the resident nesting colony of Cattle Egret (Bulbucus ibis). Yet owing to its location, it suffers from human induced impacts which include industrial and domestic effluent discharges as well as agricultural land use which have negatively impacted water quality. The current study reports the results obtained from the introductory monitoring programme of surface water quality in the Nature Reserve to emphasize the detrimental impact of the anthropogenic activities in the water quality of such an important ecosystem. The study involved physicochemical and biotic variables, microbial parameters and biological indicators. Results after 3 years of monitoring bring to evidence a poor water quality further impaired by seasonal patterns. Statistical analysis of data attributed water quality variation to 3 main parameters - pH, dissolved oxygen and nitrates, indicating heavy contamination loads from both organic and agricultural sources. Seasonality plays a role in water flow and climatic conditions, where sampling sites presented variable water quality data, suggesting a depurative function of the wetland.

    Paul Broca surmised that the short and broad-brachycephalic-skulls of the earliest European settlers had become longer and narrower-dolichocephalic-in modern populations due to the blending of different races. Swedish anatomist Anders Retzius had two brachycephalic skulls said to be from contemporary Basque individuals, a claim suited to test Broca's hypothesis. Broca worked with fellow anatomist and surgeon Pedro González Velasco, the founding father of Spanish anthropology, to gather a large number of Basque skulls. In its time, this was the most fascinating collection owned by the Anthropological Society of Paris. This article explains how Broca and Velasco were able to gather such a sizeable array of specimens, which they had collected at a location known at first by the code name of "Z." Although Broca finally concluded that the origin of the Retzius skulls could not be determined, his research was to spark anthropologists' interest in the language and origins of the Basque people.

    The LIULIN-3M instrument is a further development of the LIULIN dosimeter-radiometer, used on the MIR spacestation during 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 cm2 area is contained in the instrument. Pulse high analysis technique is used to determine the energy losses in the detector. The final data from the instrument are the flux and the dose rate for the exposure time and 256 channels of absorbed dose spectra based on the assumption that the particle flux is normal to the detector. The LIULIN-3M instrument was calibrated by proton fluxes with different energies at the Indiana University Cyclotron Facility in June 1997 and had been used for radiation measurements during commercial aircraft flights. The calibration procedure and some flight results are presented in this paper.

    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

    Students represent a population group that is for the most part in good health. However, students also face specific stresses and constraints that are likely to make it difficult for them to adapt to student life, and these adjustments can lead to unhealthy behaviours. Within Universities, the implementation of a coherent health policy must aim to positively impact on the development of both the professional and daily lives of young adults. The University of Paul Verlaine in Metz (France) has taken this perspective on board, and under the leadership of its social health department, the whole University has adopted a comprehensive policy for student well-being under the five action areas of the Ottawa Charter. This approach to well-being as a public policy strategy, through the Healthy Life policy, is central to all decisions taken at the Metz University and throughout the Regional Centre for Scholars and University Students (CROUS) in Lorraine. A number of facilities dedicated to students' health and well-being have been created in this supporting environment, and the engagement of students in the Healthy Life policy (some students 'relay' the information, others are 'peer educators') show that they are involved in the community life of the University. The introduction of teaching modules by the University's health department has given access to training to increase students' awareness of the concept of a holistic approach to health. Finally students have had improved access to healthcare services thanks to an increase in the number of activities provided by the student health department focusing on common problems experienced by university students.

    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

    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.

    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.

    Among numerous scientific contacts which Paul Ehrlich had with foreign scientists information about his contacts with East European scientists is very limited. The communiqué will deal with some of the particulars concerning Ehrlich's co-operation with physicians from East Europe directly before the practical application of the chemioterapeutics among others he was in touch with the Russians: Georgi N. Gabryczewski, Alexander A. Władimirow and a Finn Julius Iversen. The contacts originated during Robert Koch bacteriological courses at the Institute of Hygiene in Berlin. Only between 1885-1988 at least 11% of participants came from the countries of Eastern Europe. Ehrlich and Gabryczewski correspondence indicates that such a co-operation had already existed in the 90-ties, at the time of the research of a therapeutic influence of aniline dyes like diacetylparaaminophenol and triasid at spirillioza (recurrens). Iversen, a chief physician of Obuchow Hospital in St. Petersburg, was one of the first who after initial tests (Atoxyl, Arsazetin), at Ehrlich's request successfully used 606 preparation in case of spirochaeta infections.

    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)

    This inventory of reports and data concerning the Mississippi and Minnesota Rivers in the Twin Cities metropolitan area was compiled from November 1981 through January 1982 for a planned river-quality assessment to be conducted cooperatively by the U.S. Geological Survey and the Metropolitan Waste Control Commission. There are 260 annotated citations: 176 citations of reports; 8 citations of computer models that have been used to model either or both rivers; and 76 citations of data in reports , in field notes, lab sheets, or handwritten tabulations, and in computer data bases. Citations of all the reports and data located that might conceivably be useful in understanding and interpreting the biological and chemical quality of the Mississippi and Minnesota Rivers in the past, present, or future were included. The accuracy of the citations was not verified and secondary sources, such as other annotated bibliographies, were used in the compilation of this inventory.

    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.

  12. 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

    2010-09-01

    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 this DOE sponsored program, 3M achieved the critical UBT features to enable durable flexible high efficiency modules to be produced by a range of customers who have now certified the 3M UBT and are actively developing said flexible modules. 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.

    Many distal tephra beds exist in the thick, fossiliferous loess deposits near Fairbanks interior Alaska. Isothermal plateau fission-track ages, determined on glass shards from tephra beds, in conjunction with tephrostratigraphic and magnetostratigraphic techniques, indicate that loess deposition began in the late Pliocene-an antiquity previously unsuspected. Hence, there is the opportunity now to reconstruct a detailed, well-dated record of environmental changes in interior Alaska during the past 3 m.y.

    Increasing evidence shows that TIM-1 and TIM-3 in-fluence chronic autoimmune diseases, and their expression levels in immune cells from nephritic patients are still unknown. Real-time transcription-polymerase chain reaction analysis was used to deter-mine expression levels of TIM-1 and TIM-3 mRNA in peripheral blood mononuclear cells (PBMCs) from 36 patients with minimal change glo-merulopathy (MCG), 65 patients with lupus nephritis (LN), 78 patients with IgA nephropathy (IgAN), 55 patients with membranous nephropa-thy (MN), 22 patients with crescentic glomerulonephritis (CGN), 26 patients with anaphylactoid purpura nephritis (APN), and 63 healthy controls. TIM-3 mRNA expression significantly decreased in PBMCs from nephritic patients (LN, P < 0.0001; MCG, P < 0.0001; MN, P = 0.0031; CGN, P = 0.0464; IgAN, P = 0.0002; APN, P = 0.0392) com-pared with healthy controls. In contrast, there was no significant differ-ence in TIM-1 mRNA expression between the patients and the healthy controls. Our results suggest that insufficient expression of TIM-3 mRNA may be involved in the pathogenesis of nephropathy.

    A general hydrothermal synthesis technique has been developed for the large-scale preparation of perovskite oxide nanocrystals of BaTiO{sub 3} (BT), SrTiO{sub 3} (ST) and PbTiO{sub 3} (PT). X-ray diffraction pattern (XRD) and Raman spectrum revealed that tetragonal BT was successfully synthesized. The obtained ST and PT were in cubic and tetragonal phase, respectively. Scanning electronic microscopy (SEM) and transmission electronic microscopy (TEM) images showed that all of the products were on nanometer scale. These nanocrystals should provide an ideal candidate for fundamental studies of nanoscale ferroelectricity, piezoelectricity, and paraelectricity. Meanwhile, the synthetic strategy may be easily extended to prepare other nearly monodispersed nanocrystals of perovskite oxides or solid solutions. The relative studies are in progress and will be reported later.

    We report the synthesis, crystal structures, IR, and thermal, dielectric, and magnetic properties of a new series of ammonium metal formate frameworks of [HONH(3)][M(II)(HCOO)(3)] for M = Mn, Co, Ni, Zn, and Mg. They are isostructural and crystallize in the nonpolar chiral orthorhombic space group P2(1)2(1)2(1), a = 7.8121(2)-7.6225(2) Å, b = 7.9612(3)-7.7385(2) Å, c = 13.1728(7)-12.7280(4) Å, and V = 819.27(6)-754.95(4) Å(3). The structures possess anionic metal formate frameworks of 4(9)·6(6) topology, in which the octahedral metal centers are connected by the anti-anti formate ligands and the hydroxylammonium is located orderly in the channels, forming strong O/N-H···O(formate) hydrogen bonds with the framework. HONH(3)(+) with only two non-H atoms favors the formation of the dense chiral 4(9)·6(6) frameworks, instead of the less dense 4(12)·6(3) perovskite frameworks for other monoammoniums of two to four non-H atoms because of its small size and its ability to form strong hydrogen bonding. However, the larger size of HONH(3)(+) compared to NH(4)(+) resulted in simple dielectric properties and no phase transitions. The three magnetic members (Mn, Co, and Ni) display antiferromagnetic long-range ordering of spin canting, at Néel temperatures of 8.8 K (Mn), 10.9 K (Co), and 30.5 K (Ni), respectively, and small spontaneous magnetizations for the Mn and Ni members but large magnetization for the Co member. Thermal and IR spectroscopic properties are also reported. PMID:23214977

    Group II metabotropic glutamate receptors (mGluRs) comprise mGluR2 (mGlu2; encoded by GRM2) and mGluR3 (mGlu3; encoded by GRM3) and modulate glutamate neurotransmission and synaptic plasticity. Here we review the expression and function of mGluR3 and its involvement in schizophrenia. mGluR3 is expressed by glia and neurons in many brain regions and has a predominantly presynaptic distribution, consistent with its role as an inhibitory autoreceptor and heteroceptor. mGluR3 splice variants exist in human brain but are of unknown function. Differentiation of mGluR3 from mGluR2 has been problematic because of the lack of selective ligands and antibodies; the available data suggest particular roles for mGluR3 in long-term depression, in glial function and in neuroprotection. Some but not all studies find genetic association of GRM3 polymorphisms with psychosis, with the risk alleles also being associated with schizophrenia-related endophenotypes such as impaired cognition, cortical activation and glutamate markers. The dimeric form of mGluR3 may be reduced in the brain in schizophrenia. Finally, preclinical findings have made mGluR3 a putative therapeutic target, and now direct evidence for antipsychotic efficacy of a group II mGluR agonist has emerged from a randomised clinical trial in schizophrenia. Together these data implicate mGluR3 in aetiological, pathophysiological and pharmacotherapeutic aspects of the disorder. PMID:18541626

    There is a continued need to develop improved rapid methods for detection of foodborne pathogens. The aim of this project was to evaluate the 3M Molecular Detection System (3M MDS), which uses isothermal DNA amplification, and the 3M Molecular Detection Assay Listeria using environmental samples obtained from retail delicatessens and meat, seafood, and dairy processing plants. Environmental sponge samples were tested for Listeria with the 3M MDS after 22 and 48 h of enrichment in 3M Modified Listeria Recovery Broth (3M mLRB); enrichments were also used for cultural detection of Listeria spp. Among 391 samples tested for Listeria, 74 were positive by both the 3M MDS and the cultural method, 310 were negative by both methods, 2 were positive by the 3M MDS and negative by the cultural method, and one sample was negative by the 3M MDS and positive by the cultural method. Four samples were removed from the sample set, prior to statistical analyses, due to potential cross-contamination during testing. Listeria isolates from positive samples represented L. monocytogenes, L. innocua, L. welshimeri, and L. seeligeri. Overall, the 3M MDS and culture-based detection after enrichment in 3M mLRB did not differ significantly (P < 0.05) with regard to the number of positive samples, when chi-square analyses were performed for (i) number of positive samples after 22 h, (ii) number of positive samples after 48 h, and (iii) number of positive samples after 22 and/or 48 h of enrichment in 3M mLRB. Among 288 sampling sites that were tested with duplicate sponges, 67 each tested positive with the 3M MDS and the traditional U.S. Food and Drug Administration Bacteriological Analytical Manual method, further supporting that the 3M MDS performs equivalently to traditional methods when used with environmental sponge samples.

    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.

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.

    Samples of ultracold 174Yb+ ions, confined in a linear radio-frequency Paul trap, are heated via micromotion interruption, while their temperature, density, and therefore structural phase are monitored and simulated. The observed time evolution of the ion temperature is compared to a theoretical model for ion-ion heating allowing a direct measurement of the Coulomb logarithm in a linear Paul trap. This result permits a simple, yet accurate, analytical description of ion cloud thermodynamic properties, e.g., density, temperature, and structural phase, as well as suggests limits to and improvements for ongoing trapped-ion quantum information efforts.

  7. A new parallel P3M code for very large-scale cosmological simulations

    1998-12-01

    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.

    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.

  13. L2,3M1 satellites in soft x-ray emission

    Velasquez, Steven; Schnatterly, S. E.

    1988-12-01

    A systematic study of the L2,3M1 (3s-2p) transition in elements from Cl to Cr reveals a satellite of unusually large intensity (~30% of parent line). Previous work on some of these elements led to the suggestion that the satellite is due to a two-electron shakeup (configuration-interaction) process. We compare our measurements of position, width, and intensity of the satellite as a function of atomic number with the predictions of this model and extend the theory to explain the apparent disappearance of the satellite outside this range.

  14. Theoretical study of 'Mixed' ligands superhalogens: Cl-M-NO3 (M = Li, Na, K)

    2016-08-01

    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.

    2014-02-01

    Semiconductor detectors can be used to detect neutrons if they are covered by a conversion layer. Some neutrons transfer their kinetic energy to hydrogen via elastic nuclear scattering in the conversion layer, and protons are produced as recoils. These protons enter the sensitive volume of the detector and are detected. In the process of detector development, Monte Carlo computer codes are necessary to simulate the detection process. This paper presents the main features of the S3M code (SRIM Supporting Software Modules) and shows its application potential. Examples are given for the neutron detectors with a conversion layer and for CVD (Chemical Vapor Deposition) diamond detectors for beam-condition monitors at the LHC (Large Hadron Collider). Special attention is paid to the S3M statistical modules that can be of interest also for other application areas like beam transport, accelerators, ion therapy, etc. The results are generated by MCNPX (Monte Carlo N-Particle eXtended) simulations used to optimize the thickness of the HDPE (high density polyethylene) conversion layer.

    Aryabhatta Research Institute of Observational Sciences (ARIES) had set up a 1.3 m telescope at Devasthal, Nainital, India in the year 2010. Country's largest roll-off roof was indigenously designed, fabricated and installed on top of a building (17 × 8 m) for housing 1.3 m telescope. Telescope was supplied by M/s DFM Engineering Inc., USA to ARIES and was installed in the building with unique roll-off roof to protect it from external environment. Roll-off roof was designed and fabricated considering various parameters and available manpower and resources at ARIES. This paper presents mechanical development work, simple but distinct design approach and innovative selection of materials to economically manufacture roll-off roof of large size (8 × 8 × 4 m) at hilly remote site of Devasthal situated in Central Himalayan region. All operations in the roof viz. opening of shutters and rolling of roof were motorized to facilitate observers during night observations.

    1994-04-01

    Far-infrared laser interferometry at 432 µm was carried out on the STP-3(M) reversed-field pinch. Measurements along two vertical chords showed a change from a parabolic-like to a flat-like electron density profile after field reversal. A density profile inversion and a correlated toroidal magnetic flux perturbation were also observed during the transition from the current rising to the current decay phase. Measurements of electron density fluctuations indicated relative fluctuation levels of ˜10% for both chords during the current rising phase and ˜5% and ˜15% during the current decay phase for the central and outer chords, respectively. Spectral analysis showed a ˜30 kHz mode consistent with poloidal mode number m=0 magnetic fluctuations, and a ˜90 kHz mode localized to the outer region of the plasma, which was strongly excited during the current decay phase and may be connected to particle and energy transport in STP-3(M).

  3. Differential targeting of VDAC3 mRNA isoforms influences mitochondria morphology

    Michaud, Morgane; Ubrig, Elodie; Filleur, Sophie; Erhardt, Mathieu; Ephritikhine, Geneviève; Maréchal-Drouard, Laurence; Duchêne, Anne-Marie

    2014-01-01

    Intracellular targeting of mRNAs has recently emerged as a prevalent mechanism to control protein localization. For mitochondria, a cotranslational model of protein import is now proposed in parallel to the conventional posttranslational model, and mitochondrial targeting of mRNAs has been demonstrated in various organisms. Voltage-dependent anion channels (VDACs) are the most abundant proteins in the outer mitochondrial membrane and the major transport pathway for numerous metabolites. Four nucleus-encoded VDACs have been identified in Arabidopsis thaliana. Alternative cleavage and polyadenylation generate two VDAC3 mRNA isoforms differing by their 3′ UTR. By using quantitative RT-PCR and in vivo mRNA visualization approaches, the two mRNA variants were shown differentially associated with mitochondria. The longest mRNA presents a 3′ extension named alternative UTR (aUTR) that is necessary and sufficient to target VDAC3 mRNA to the mitochondrial surface. Moreover, aUTR is sufficient for the mitochondrial targeting of a reporter transcript, and can be used as a tool to target an unrelated mRNA to the mitochondrial surface. Finally, VDAC3–aUTR mRNA variant impacts mitochondria morphology and size, demonstrating the role of mRNA targeting in mitochondria biogenesis. PMID:24889622

    NASA Technical Reports Server (NTRS)

    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.'

    On May 18, 1980 an earthquake beneath the north side of Mt. St. Helens triggered the eruption of this volcano. This eruption caused damage to 160,000 acres of forests, meadows, lakes and streams. This paper discussed the reforestation of approximately 50,000 acres of devastated land which was located around the site of the eruption. It also discussed the natural recovery of this area and the reestablishment of ecosystems and rebuilding of habitats by the plants and animals.

    The St. Louis Motor, invented in 1909, is unique among physics apparatus for being named for a geographical place rather than a physicist. The sturdy little device (Fig. 1) has never been out of production. Any older school or physics department that has not done a catastrophic housecleaning in the last 20 years will certainly have a small flock of them in the back room.

    Results are presented from experimental and theoretical investigations of oscillatory and wave phenomena observed in the edge region in the U-3M torsatron during plasma creation and heating by an RF discharge in the ICR frequency range, accompanied by a transition to improved confinement. The main results are reported of diagnostic measurements of the spectral composition of oscillations, as well as of how the phase and amplitude relationships depend on time and on the RF power during its injection into the plasma. The measurements were carried out with electrostatic probes positioned at the edge of the plasma confinement region. The experimental results are interpreted using the kinetic theory of the electron-ion parametric instability of a plasma in the ion cyclotron frequency range and are compared with the results of numerical simulations.

    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.

    A class of superalkalies OM3 (M = Li, Na, K) and their corresponding cations OM3+ were theoretically investigated. The OM3 molecules possess very low adiabatic ionization potentials (AIPs) of 2.842-3.558 eV at the CCSD(T)/6-311+G(3df) level. It was found that the ionization potentials of OM3 depend on the nature of the peripheral ligand atom and can be efficiently decreased upon replacing the M atom with the more electropositive one. Such superalkalies characterized by lower ionization potentials add candidates to the research on superatoms and can be used in the synthesis of new nontraditional salts where strong reducers are involved.

    The experimental observation that vanadate superlattices (LaVO3)m/SrVO3 show ferromagnetism up to room temperature (Lüders U. et al., Phys. Rev. B, 80 (2009) 241102(R)) is investigated by means of density functional theory, and the band structure for m = 5 and 6 is calculated. A buckling of the interface VO2 layers is found in both cases, but subtle differences in bond length lead to very different properties for even and odd values of m: in the even case, the two interface VO2 layers effectively decouple from the adjacent LaO layers due to a strong bond length enhancement. This results into a local inversion of the orbital occupancy and to the confinement of the charge carriers. In the odd case, the amplitude of the bond length variation is smaller, so that the charge carriers spill into the deeper-lying VO2 layers, and spin-polarised interfaces are obtained.

    In an inauspicious start to the ultimately very successful installation of the Dark Energy Camera on the V. M. Blanco 4- m telescope at CTIO, the light-weighted Cer-Vit 1.3-m-diameter secondary mirror suffered an accident in which it fell onto its apex. This punched out a central plug of glass and destroyed the focus and tip/tilt mechanism. However, the mirror proved fully recoverable, without degraded performance. This paper describes the efforts through which the mirror was repaired and the tip/tilt mechanism rebuilt and upgraded. The telescope re-entered full service as a Ritchey- Chrétien platform in October of 2013.

    The first hydrolysis constant of Eu(sup 3+) has been determined at 303 K and 3 M (NaCl) ionic strength. A solvent extraction method was used, the extractant was dibenzoylmethane in benzene and di glycolate anion in the aqueous phase provided competitive complexation. The tracer solution was (sup 152m1) Eu (III) in water. The radioactive solution of europium was obtained by neutron irradiation of europium nitrate solutions at pH 3.0, in a TRIGA Mark III nuclear reactor at a neutron flux of 1 x 10(exp 13) cm(sup -2) s(sup -1). The half life of the produced isotope, (sup 152m1) Eu (9.3 h), was verified by means of a Ge H detector and no interfering radiations were observed in the spectra.

    St. Kitts and Nevis have areas of 68 and 36 square miles respectively and the terrain is mountainous. The population is 45,800 total and the annual growth rate is .2%. The ethnic make up is almost all black African with some British, Portuguese, and Lebanese. The religions are primarily Anglican, with evangelical Protestant and Catholic minorities. Infant mortality stands at 41/1000. The government is a constitutional monarchy with a Westminster type parliament. There is a governor, a prime minister, a cabinet, an 11 -member appointed upper house and a 11- member elected house of representatives. 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.

  6. 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.

  8. 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

    On May 18, 1980, Mount St. Helens, Washington exploded in a spectacular and devastating eruption that shocked the world. The eruption, one of the most powerful in the history of the United States, removed 2.7 cubic kilometers of rock from the volcano's edifice, the bulk of which had been constructed by nearly 4,000 years of lava-dome-building eruptions. In seconds, the mountain's summit elevation was lowered from 2,950 meters to 2,549 meters, leaving a north-facing, horseshoe-shaped crater over 2 kilometers wide. Following the 1980 eruption, Mount St. Helens remained active. A large lava dome began episodically extruding in the center of the volcano's empty crater. This dome-building eruption lasted until 1986 and added about 80 million cubic meters of rock to the volcano. During the two decades following the May 18, 1980 eruption, Crater Glacier formed tongues of ice around the east and west sides of the lava dome in the deeply shaded niche between the lava dome and the south crater wall. Long the most active volcano in the Cascade Range with a complex 300,000-year history, Mount St. Helens erupted again in the fall of 2004 as a new period of dome building began within the 1980 crater. Between October 2004 and February 2006, about 80 million cubic meters of dacite lava erupted immediately south of the 1980-86 lava dome. The erupting lava separated the glacier into two parts, first squeezing the east arm of the glacier against the east crater wall and then causing equally spectacular crevassing and broad uplift of the glacier's west arm. Vertical aerial photographs document dome growth and glacier deformation. These photographs enabled photogrammetric construction of a series of high-resolution digital elevation models (DEMs) showing changes from October 4, 2004 to February 9, 2006. From the DEMs, Geographic Information Systems (GIS) applications were used to estimate extruded volumes and growth rates of the new lava dome. The DEMs were also used to quantify dome

    A method for determining the background geothermal gradient values through the analysis of temperature measurements at multiple depths to 3 m and recorded over a time span of several days is presented. The analysis is based on the amplitude decay and phase shift of temperature waves with depth. Diurnal and other high frequency temperature variations are used to compute thermal diffusivities which in turn are used to model and remove the effect of the annual temperature wave. The analysis considers both a homogeneous half space and a two layer medium consisting of an overburden of finite thickness overlying a semi-infinite substratum. The method was tested in three holes in the Crystal Hot Springs geothermal field. Temperatures in each hole were recorded once a minute over a period of three days with a probe containing thermistors at eight different depths. Five of the thermistors were positioned at shallow depths (less than or equal to 0.5 m) to monitor diurnal and other high frequency waves and three at greater depths (greater than or equal to 1 m) to measure lower frequency variations. Since measurements were recorded at only three sites, the accuracy and reliability of the method is not fully evaluated. Potential problems to the method resulting from inaccurate model parameters and convective heat transport are investigated.

    3M has developed technology for selectively removing trace levels of dissolved contaminant materials from liquids using systems operating at flow rates up to 50 gallons per minute. This technology combines active particle chemistries with a particle-loaded membrane to achieve a new medium for liquid waste processing--a spiral wound filter cartridge. This technology has shown success by generating high decontamination factors and reducing contaminants to part per trillion levels. The spiral wound cartridge offers simplified installation, convenient replacement, and clean, easy disposal of a concentrated waste. By incorporating small, high surface area particles (5 to 80 microns) into a sturdy, yet porous, membrane greater removal efficiencies of even trace contaminants can be achieved at higher flow rates than with conventional column systems. In addition, the captive-particle medium prevents channeling of liquids and insures uniform flow across the sorbing particle surface. The cartridges fit into standard, commercially-available housings and whole system capital costs are substantially lower than those of column or reverse osmosis systems. Developmental work at high degrees of water polishing have included removal of mercury from contaminated wastewater, various radionuclides from process water, and organometallic species from surface water discharges. Laboratory testing and on-site demonstration data of these applications show the levels of success that have been achieved thus far.

    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.

    2010-10-01

    The GRACOS (GRAvitational COSmology) code, a parallel implementation of the particle-particle/particle-mesh (P3M) algorithm for distributed memory clusters, uses a hybrid method for both computation and domain decomposition. Long-range forces are computed using a Fourier transform gravity solver on a regular mesh; the mesh is distributed across parallel processes using a static one-dimensional slab domain decomposition. Short-range forces are computed by direct summation of close pairs; particles are distributed using a dynamic domain decomposition based on a space-filling Hilbert curve. A nearly-optimal method was devised to dynamically repartition the particle distribution so as to maintain load balance even for extremely inhomogeneous mass distributions. Tests using 800(3) simulations on a 40-processor beowulf cluster showed good load balance and scalability up to 80 processes. There are limits on scalability imposed by communication and extreme clustering which may be removed by extending the algorithm to include adaptive mesh refinement.

    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.

    This report documents both closed- and open-set speech recognition performance for 18 adult experienced users of the 3M/House single-channel cochlear implant. The stimuli included tape-recorded, standard word and sentence recognition tests, an environmental-sound test, nonsense syllables, and sentences presented in auditory (implant-only), visual, and auditory-visual modes. All subjects were tested individually in a single session using their own cochlear implants, set to typical comfort use settings for running speech. Subjects' oral responses to the stimuli were transcribed by the experimenters and scored for percent correct. The results revealed considerable individual differences among the subjects and their performance on different tests. All subjects scored better than chance on the closed-set tests. Although they performed considerably poorer on the open-set tests, approximately half of these subjects demonstrated at least some open-set word recognition, a finding not previously reported in the literature for this device. All subjects performed better on the auditory-visual sentences than on either the auditory or visual conditions alone. These results contribute to the database on speech perception by cochlear implant users and show that open-set word recognition performance was somewhat better for these subjects using this implant than would have been predicted from the literature.

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

    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.

    2016-10-01

    Pulsation period changes in Mira type variables are investigated using the stellar evolution and nonlinear stellar pulsation calculations. We considered the evolutionary sequence of stellar models with initial mass {M_{ZAMS}} = 3{M_⊙} and population I composition. Pulsations of stars in the early stage of the asymptotic giant branch are shown to be due to instability of the fundamental mode. In the later stage of evolution when the helium shell source becomes thermally unstable the stellar oscillations occur in either the fundamental mode (for the stellar luminosuty L < 5.4 × {10^3}{L_⊙}) or the first overtone (L > 7 × {10^3}{L_⊙}). Excitation of pulsations is due to the κ-mechanism in the hydrogen ionization zone. Stars with intermediate luminosities 5.4 × {10^3}{L_⊙} < L < 7 × {10^3}{L_⊙} were found to be stable against radial oscillations. The pulsation period was determined as a function of evolutionary time and period change rates dot Π were evaluated for the first ten helium flashes. The period change rate becomes the largest in absolute value (dot Π/Π ≈ - {10^{ - 2}}y{r^{ - 1}}) between the helium flash and the maximum of the stellar luminosity. Period changes with rate | {dot Π/Π } | ≥slant - {10^{ - 3}}y{r^{ - 1}} take place during ≈500 yr, that is nearly one hundredth of the interval between helium flashes.

    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.

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.

    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.

    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.

    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

  4. Stability Diagrams for Paul Ion Traps Driven by Two-Frequencies.

    2016-07-14

    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.

    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.

    Paul of Aegina (625-690 AD) was born on the island of Aegina and was one of the most prominent physician-writers of the Byzantine Empire. His work Epitome of Medicine, comprised of 7 books, was a comprehensive compendium of the medical and surgical knowledge of his time and was subsequently translated into multiple languages. Paul of Aegina made valuable contributions to neurosurgical subjects and described procedures for the treatment of nerve injuries, hydrocephalus, and fractures of the skull and spine. His work combined the ancient knowledge of Hippocrates and Galen with contemporary medical observations and served as a bridge between Byzantine and Arabic medicine. He is considered to be one of the great ancient Greek medical writers and his work has influenced the subsequent evolution of Western European and Arab medicine. This paper provides an account of his contribution to the management of neurosurgical pathologies during the Byzantine era, as described in his medical compendium, Epitome of Medicine. PMID:24032699

    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.

    This paper has examined the relationship between the life and the thought of Jean-Paul Sartre. The central themes of Sartre's personal existence are shown to revolve around a struggle for self-definition and self-formation, rooted in the empathic failures of significant others during his formative years. It is argued that Sartre's experience of this struggle is mirrored and symbolized by the dialectic of being and nothingness which constitutes the central preoccupation of his philosophy.

    Under a joint agreement between the National Aeronautics and Space Agency (NASA) and the Russian Aviation and Space Agency (RASA), the Stratospheric Aerosol Gas Experiment III (SAGE III) instrument was launched in low earth orbit on December 10, 2001 aboard the Russian Meteor-3M(1) satellite from the Baikonur Cosmodrome. 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. It has provided vital ozone and aerosol data in the mid latitudes and has contributed vastly in ozone depletion research. Ball Aerospace built the instrument under Langley Research Center's (LaRC) management. This paper presents the process and approach deployed by the SAGE III and the Meteor teams in performing the initial on-orbit checkout. It further documents a number of early science results obtained by deploying low risk, carefully coordinated procedures in resolving the serious operational

  15. PLANET ENGULFMENT BY {approx}1.5-3 M{sub sun} RED GIANTS

    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.

    We report the system/optics design and performance of the dome flat-field system for the Araki Telescope, a 1.3- m optical/near-infrared telescope at Koyama Astronomical Observatory in Japan. A variety of instruments are attached to the telescope. The optical imager, which is intended to search for exoplanets, requires an illumination flatness within 1% on the focal plane over the 17-arcmin FOV. Illumination flatness at both the pupil plane and the focal plane of the telescope is essential for calibration of the transmittance of the optical system. We devised an optical design for the flat-field system that satisfies illumination flatness at both the focal and pupil planes using the non-sequential ray tracing software LightTools. We considered far-field illumination pattern of the lamps, scattering surface reflectance distribution of the screen, telescope structure, primary/secondary mirrors, and mirror baffles. We achieved a flat illumination distribution of 0.9% at the focal plane. The systems performance was tested by comparison with a cloud-flat frame, which was derived by imaging cloud cover illuminated by city lights. The calibration data for the dome flat-field system agree well with the cloud-flat frame within 1% for the g' and i' bands of the imager, but the r0 band data does not meet the requirement (less than or equal to 2). Moreover, various instruments require a focal plane illuminance ranging over three orders of magnitude. We used six high-power (60W) halogen lamps; the output power is remotely controlled by a thyristor-driven dimmer and a bypass circuit to an autotransformer.

    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.

  19. 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 .

  20. The effects of barometric pressure according to Paul Bert: the question today.

    PubMed

    Dejours, P; Dejours, S

    1992-10-01

    The scientific activity of Paul Bert was very diverse, but his main achievements concern the effects of barometric pressure upon life. The fundamental physiological effect of decreasing barometric pressure is due to the concomitant fall of the O2 partial pressure. The effects of lowering or raising the barometric pressure can be countered by increasing or decreasing the O2 fraction in the air. Extreme hyperoxia modifies cellular metabolism of all living beings: this is O2 poisoning, the Paul Bert effect. Rapid decompressions from several atmospheres, or even from sea level to high altitude, can entail the formation of bubbles of N2 dissolved under the high pressure in the tissues and blood. Decompression accidents may be prevented by decompressing slowly. Immediate recompression is the only way to overcome decompression accidents, as the N2 is forced back into solution. These main discoveries were not universally accepted before about 1915. However, since Paul Bert's time, some additional effects of changes of the barometric pressure, for example related to the variation of gas diffusivity and density, have been pointed out. It is also clear that some factors other than low barometric pressure, for instance radiation, temperature, humidity etc. may play important roles in the mechanism of mountain sickness. However, it remains that the main factor is hypoxia, since oxygen inhalation or recompression lead to a quick recovery.

    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.

    A linear Paul trap (LPT) enables ions to be trapped for use in a variety of experiments. In many of these experiments, such as those measuring charge exchange or sympathetic cooling, the decay of ions from the trap is used to measure some quantity of interest. This decay is typically modeled as a single exponential. We have found that in cases where the trap is loaded to high numbers of ions, the ion decay is better described by a double exponential decay function. We have experimentally examined the decay of ions from an LPT loaded by photoionization from a magneto-optical trap as a function of the q stability parameter of the Paul trap. The LPT is loaded to steady-state, then the loading is stopped and the number of trapped ions as a function of time is monitored to determine the decay. We present numerical simulations and experimental results that demonstrate two distinct regions in the decay. For high steady-state values, the trap exhibits a double-exponential behavior. However, if the trap is filled to a steady-state value below a threshold, the decay recovers the typical single-exponential behavior. This behavior should be universal to any Paul trap regardless of the geometry or species trapped. NSF Grant No. PHY-1307874.

    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

    This articles focuses on John Paul II's 1993 Veritatis Splendor, an 1798 page encyclical letter to the Church's bishops on the crisis in the Catholic Church of family limitation and the implications for the laity and society. The communication states that a flexible interpretation of theology must be abandoned. Paul VI's 19963 Humanae Vitae is reportedly affirmed. John XXIII's spiritualism and concern with conscience is ignored. This encyclical is identified as not spoken "ex cathedra" or from the throne, which would have made the pronouncement true, unarguable forever, and subject to excommunication for those disobeying. Pope John Paul II is said to be preparing another encyclical on life issues and sexuality. Reference is made in this encyclical to devices that are acceptable to use to gauge a safe period for copulation without impregnation. The devices include the rectal thermometer and the calculator for determining the infertile days in the natural cycle. Veritatis Splendor's position on fertility is viewed as an issue of loyalty to the Church and not as an honest evaluation of the moral implications of artificial birth control. This encyclical comes closer to "ex cathedra" than the Humanae Vitae, which banned the birth control pill, IUD, spermicides, hormonal implants, vasectomies, and tubal ligation. Liberal Catholic theologians are reported to have interpreted Paul VI's statement that "God illuminates from within the hearts of the faithful and invites their assent," as a validation of dissent. Pope John Paul II closes the door to dissent in this proclamation. The Church also closes the door to free will for people to decide for themselves. The Jesuits, with different notions of divine will, are described as potentially concluding that the denial of free will and individual reason for the sake of Papal supremacy must be the work of the devil himself. For good Catholics this encyclical is interpreted as potentially forcing even stronger opposition to the

    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.

  10. Anisotropic surface melting in lyotropic cubic crystals. Part 1: Pn3m/L1 interface, poor faceting

    2006-02-01

    From experiments with ice or metal crystals, in the vicinity of their crystal/liquid/vapor triple points, it is known that melting of crystals starts on their surfaces and is anisotropic. It is shown here by direct observations under an optical microscope that this anisotropic surface melting phenomenon occurs also in lyotropic systems. In the case of C12EO2/water mixture, it takes place in the vicinity of the peritectic Pn3m/L3/L1 triple point. Above the peritectic triple point, where the Pn3m and L1 phases coexist in the bulk, the surface of a Pn3m-in-L1 crystal is composed of (111)-type facets surrounded by rough surfaces. The angular junction suggests that rough surfaces are wet by a L3-like layer while facets stay “dry”. This is analogous to the pre-melting at rough surfaces in solid crystals. Upon cooling below the peritectic triple point, where L3 and L1 phases coexist in the bulk, a thick layer of the L3 phase grows from the pre-melted, rough Pn3m/L1 interface. Simultaneously, facets stay dry and their radius decreases. In this tri-phasic configuration, stable in a narrow temperature range, the L3/L1 and L3/Pn3m interfaces have shapes of constant mean curvature surfaces having common borders: edges of facets.

    Cell death abnormal (ced)-3 and ced-4 genes regulate apoptosis to maintain tissue homeostasis in Caenorhabditis elegans. Apoptosome formation and CED-4 translocation drive CED-3 activation. However, the precise role of CED-4 translocation is not yet fully understood. In this study, using a combination of immunoprecipitation and reverse transcription-polymerase chain reaction methods in cells and a glutathione-S-transferase pull down assay in a cell-free system, we show that CED-4 binds ced-3 mRNA. In the presence of ced-3 mRNA, CED-4 protein is enriched in the microsomal fraction and interacts with ribosomal protein L10a in mammalian cells, increasing the levels of CED-3. These results suggest that CED-4 forms a complex with ced-3 mRNA and delivers it to ribosomes for translation.

  12. 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

    NASA Astrophysics Data System (ADS)

    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.

    continuing expansion of the nearby Minneapolis-St. Paul metropolitan region has degraded or destroyed many woodlots, upland fields, and wetlands. In numerous instances, degradation of natural habitats has influenced the abundance and distribution of bird species. Because of these changes, both the Federal government and State Departments of Natural Resources have listed several species in various categories based on their current status. In the St. Croix River Valley, seven species are endangered, eight are threatened, and 29 are watch or priority status in either or both states. Data presented in this report are of value to land managers, land use specialists, and ornithologists, in assessing current and projected habitat alterations on the avifauna of this valley. The St. Croix River bisects a large region of western Wisconsin and east central Minnesota that exhibits a wide range of habitat types. This region supports not only birds, but many mammals, fishes, reptiles and amphibians, and several thousand species of vascular and nonvascular plants. The river itself is relatively clean through most of its course, and its natural flow is interrupted by only two small dams. Because the river lies within a 1-day drive of nearly 10 million people (Waters 1977), use of the area for recreational purposes is extremely heavy. Recreational pursuits include sunbathing, boating, and wild river kayaking in the summer, and ice fishing and cross-country skiing in the winter. The large number of unique and highly fragile habitats that exist there may never be compatible with the uses and abuses of the land that go with expanding human populations. Through the efforts of a number of citizens concerned with the quality of their environment and the foresightedness of several local, State, and Federal legislators, a portion of the upper St. Croix River Valley (hereafter termed 'the Valley') was established as a National Wild and Scenic River.

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

    SciTech Connect

    Gibbs, Gerald V.; Ross, Nancy L.; Cox, David F.; Rosso, Kevin M.

    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

    We investigate the problem of a single ion in a radio-frequency trap immersed in an ultracold Bose gas in either a condensed or a noncondensed phase. We develop a master-equation formalism describing the sympathetic cooling, and we determine the cooling rates of ions. We show that the cold atomic reservoir modifies the stability diagram of the ion in the Paul trap, creating regions where the ion is either cooled or heated due to the energy quanta exchanged with the time-dependent potential.

    2001-08-01

    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.

    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 use of air to attempt to reattach the retina dates back to 1909. However, despite the widespread use of intraocular air in the 1950s and 1960s, retinal surgeons struggled with the main limitation of the device (ie, the relatively short duration of the gas within the vitreous cavity). Fortuitous events in the late 1960s allowed Paul Sullivan, MD, to introduce the first expansile gas, sulfur hexafluoride, to Edward W.D. Norton, MD, and his colleagues at the University of Miami. The use of sulfur hexafluoride helped revolutionize retinal detachment surgery and allowed for further advances in treating other posterior segment diseases.

    In the 1950s, Sir Henry Hallett Dale undertook to compile and publish all the scientific papers of Nobel laureate Paul Ehrlich. He was assisted in this venture by Dr. Fred Himmelweit and by Ehrlich's former secretary, Martha Marquardt. A four-volume series was announced, but only three volumes saw the light of day, between 1957 and 1960. This report presents the result of a five-year effort to determine the reason for the failure to complete the undertaking, in which all potential sources were pursued and queried. In the end, the mystery remains unsolved.

    The authors propose to define as main characterization of plastic reconstructive surgery the conceptual thinking that leads to a rational choice of an operative treatment. Conceptual thinking in plastic surgery started halfway the nineteenth century with the first schematic representations of the operative procedures available at that time, in which Von Ammon and Baumgarten, Szymanowski and Denucé played a prominent role. These four authors and their works are presented with special attention for the less known of them, Jean-Paul Denucé, surgeon in Bordeaux.

    Estacio argues for critical health psychology to take action to address three issues raised (unintentionally) in the 'Harry and Paul' sketch broadcast on British television. It is suggested that, although attempting humour, the sketch offensively reflected and reproduced patterns of social injustice that are far from funny. We argue here that micro-level analysis of the interactional elements of the sketch provides an understanding of how in everyday contexts Filipino workers are constructed in socially unjust terms and of how abuse can be justified. Such an understanding can allow critical health psychology to make a distinctive contribution to these topics.

    One hundred years ago the birth of immunology was made official by the Nobel Prize award to Elie Metchnikoff and Paul Ehrlich. Metchnikoff discovered phagocytosis by macrophages and microphages as a critical host-defense mechanism and thus is considered the father of cellular innate immunity. Ehrlich described the side-chain theory of antibody formation and the mechanisms of how antibodies neutralize toxins and induce bacterial lysis with the help of complement and thus is considered one of the fathers of humoral adaptive immunity. Despite many discordant discussions in the initial phase after these discoveries, innate and adaptive responses are now known to be complementary partners in producing robust immunity.

    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.

    The wheel-lock (WL) model for depressed ambulatory activity in rats has shown metabolic maladies ensuing within 53-173 h after WL begins. We sought to determine if WL beginning after 21-23 days of voluntary running in growing female Wistar rats affected the mRNA profile in the polyribosomal fraction from plantaris muscle shortly following WL. In experiment 1, WL occurred at 0200 and muscles were harvested at 0700 daily at 5 h (WL5h, n = 4), 29 h (WL29h, n = 4), or 53 h (WL53h, n = 4) after WL. Affymetrix Rat Gene 1.0 ST Arrays were used to test the initial question as to whether WL affects mRNA occupancy on skeletal muscle polyribosomes. Using a false discovery rate of 15%, no changes in mRNAs in the polyribosomal fraction were observed at WL29h and eight mRNAs (of over 8,200 identified targets) were altered at WL53h compared with WL5h. Interestingly, two of the six downregulated genes included ankyrin repeat domain 2 (Ankrd2) and cysteine-rich protein 3/muscle LIM protein (Csrp3), both of which encode mechanical stretch sensors and RT-PCR verified their WL-induced decline. In experiment 2, whole muscle mRNA and protein levels were analyzed for Ankrd2 and Csrp3 from the muscles of WL5h (4 original samples + 2 new), WL29h (4 original), WL53h (4 original + 2 new), as well as WL173 h (n = 6 new) and animals that never ran (SED, 4-5 new). Relative to WL5h controls, whole tissue Ankrd2 and Csrp3 mRNAs were lower (P < 0.05) at WL53h, WL173h, and SED; Ankrd2 protein tended to decrease at WL53h (P = 0.054) and Csrp3 protein was less in WL173h and SED rats (P < 0.05). In summary, unique early declines in Ankrd2 and Csrp3 mRNAs were identified with removal of voluntary running, which was subsequently followed by declines in Csrp3 protein levels during longer periods of wheel lock.

    The Paul-Mohr-Coulomb failure criterion includes the intermediate principal stress σII and friction angles at the limiting stress states of σII = σIII and σII = σI, where σI and σIII are major and minor principal stresses. Conventional triaxial compression (σII = σIII), extension (σII = σI), and plane strain (σI ≠ σII ≠ σIII) experiments were performed on dry rock. The failure data were plotted in principal stress space, and material parameters were determined in the context of two internal friction angles and the theoretical uniform triaxial (all-around equal) tensile strength. Assuming isotropy, the triaxial compression and extension results were used to construct a six-sided pyramidal failure surface, and the extension friction angle was larger than the compression friction angle, a sufficient but not necessary condition of the intermediate stress effect. To capture the behavior of the rock in multiaxial loading, the Paul-Mohr-Coulomb criterion was extended to form a 12-sided pyramid with best fit planes.

    2009-01-01

    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.

    Alongside his brilliant scientific and administrative career, Paul Louis Simond, a famous colonial doctor, was also an observer of nature and excellent botanist. Following in the tradition begun two centuries earlier by medical doctors and pharmacists in the marine and army health services, Paul Louis Simond showed particularly interest in the family of Indichenese orchids during the third visit he made to the country in 1914-1917, while he was inspector of the health service. There remain a splendid collection of 226 watercolours depicting the different species of orchids which he had painted by a local artist on live model he was cultivating himself or had had sent to him from all over Indochina both officially and privately. Most of the plates he determined himself, accompanying them by a thorough and exact hand-written description of the floral organs allowing their identification. His knowledge in the area was worthy of a professional and he contributed largely to the botanical description of a region which is still far from being completed. Whilst the plates in the collection are of unequal scientific value (sometimes they are unfinished or without a detailed floral description, or they are copies of already existing plates), the greater part (160) constitutes a considerable original contribution to the knowledge of Indochinese orchidological flora (21 types). The entire collection was bequeathed in 1947 to the laboratoire of Phanérogamie of the Muséum National d'Histoire naturelle, where it can be consulted by scholars.

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 p Ψ q -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.

    Results of a series of single sided lapping experiments designed to develop appropriate conditioning methods for 3M Trizact Diamond Tile fixed abrasives are reported. Trizact™ Diamond Tile is a structured fixed abrasive lapping technology developed by 3M. The Trizact™ Diamond Tile structured abrasive pad consists of an organic (polymeric binder)-inorganic (abrasive mineral, i.e., diamond) composite that is used with a water-based coolant. The effect of platen and conditioner speed on pad wear will be explored for a roller yoke single-side lapping machine. Pad break-in conditioning was studied in detail for a 6 micron Trizact™ Diamond Tile abrasive used to lap soda-lime glass.

    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 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.

  18. Design of multichord Hα detector arrays for the U-3M torsatron and identification of rotating plasma perturbations

    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.

  20. Did Paul Kammerer discover epigenetic inheritance? A modern look at the controversial midwife toad experiments.

    PubMed

    Vargas, Alexander O

    2009-11-15

    The controversy surrounding the alleged Lamarckian fraud of Paul Kammerer's midwife toad experiments has intrigued generations of biologists. A re-examination of his descriptions of hybrid crosses of treated and nontreated toads reveals parent-of-origin effects like those documented in epigenetic inheritance. Modification of the extracellular matrix of the egg as described by Kammerer provides a plausible cause for altered gene methylation patterns. Traits such as altered egg and adult body size in Kammerer's "treated" toads are inherited epigenetically in other tetrapods. A preliminary model involving the environmental silencing of a maternally inherited allele can be attempted to explain the midwife toad experiments. Given available molecular tools and our current understanding of epigenetics, new experimentation with the midwife toad is strongly encouraged.

  1. Off-resonance energy absorption in a linear Paul trap due to mass selective resonant quenching.

    Linear Paul traps (LPT) are used in many experimental studies such as mass spectrometry, atom-ion collisions, and ion-molecule reactions. Mass selective resonant quenching (MSRQ) is implemented in LPT either to identify a charged particle's mass or to remove unwanted ions from a controlled experimental environment. In the latter case, MSRQ can introduce undesired heating to co-trapped ions of different mass, whose secular motion is off resonance with the quenching ac field, which we call off-resonance energy absorption (OREA). We present simulations and experimental evidence that show that the OREA increases exponentially with the number of ions loaded into the trap and with the amplitude of the off-resonance external ac field.

    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.

    Here we present results stemming from the first prototype of the Neutron Microscope instrument at Paul ScherrerInstitut (PSI). 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.

    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.

    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.

    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.

    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.

    This article summarizes discussions that took place following Paul Toro's presidential address for the Society for Community Research and Action (SCRA). Toro argued that community psychology and SCRA are "big tents." He suggested growth through increasing the involvement of ethnic minorities, community practitioners, international colleagues, students and early career professionals and individuals from allied disciplines. Themes in the discussions included: the founding values of community psychology, diversity, and social action. Those present felt that the field was facing a 'mid-life crisis' and needed to re-establish its identity. Newer professionals looked to their seasoned colleagues to help define and establish that identity, and involve them in the process. Respondents were supportive of increased involvement of individuals from oppressed groups and practitioners in SCRA. Less attention was paid to increasing the role of international colleagues, professionals from allied disciplines, and members of the community. PMID:15792092

    2006-01-01

    In 1957, Francis Crick outlined a startling vision of life in which the great diversity of forms and shapes of macromolecules was encoded in the one-dimensional sequence of nucleic acids. This paper situates Crick's new vision in the debates of the 1950s about protein synthesis and gene action. After exploring the reception of Crick's ideas, it shows how they differed radically from a different model of protein synthesis which enjoyed wide currency in that decade. In this alternative model, advocated by Linus Pauling and other luminaries, three-dimensional templates directed the folding of proteins. Even though it was always considered somewhat speculative, this theory was supported by a number of empirical results originating in different experimental systems. It was eventually replaced by a model in which the forms and shapes of macromolecules resulted solely from their amino acid sequence, dramatically simplifying the problem of protein synthesis which Crick was attempting to solve in 1957.

  10. 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.

    Following the discovery of mast cells (or mastzellen) by the prolific physician researcher, Paul Ehrlich, many advances have improved our understanding of these cells and their fascinating biology. The discovery of immunoglobulin E and receptors for IgE and IgG on mast cells heralded further in vivo and in vitro studies, using molecular technologies and gene knockout models. Mast cells express an array of inflammatory mediators including tryptase, histamine, cytokines, chemokines, and growth factors. They play a role in many varying disease states, from atopic diseases, parasitic infections, hematological malignancies, and arthritis to osteoporosis. This review will attempt to summarize salient evolving areas in mast cell research over the last few centuries that have led to our current understanding of this pivotal multifunctional cell.

    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.

    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

    Nurse educators recognize that many nursing students have difficulty in making decisions in clinical practice. The ability to make effective, informed decisions in clinical practice requires that nursing students know and apply the processes of critical thinking. Critical thinking is a skill that develops over time and requires the conscious application of this process. There are a number of models in the nursing literature to assist students in the critical thinking process; however, these models tend to focus solely on decision making in hospital settings and are often complex to actualize. In this paper, Paul's Model of Critical Thinking is examined for its application to nursing education. I will demonstrate how the model can be used by clinical nurse educators to assist students to develop critical thinking skills in all health care settings in a way that makes critical thinking skills accessible to students.

    The German-Swiss modernist painter Paul Klee (1879-1940) suffered in the final years of his life from a severe illness, diagnosed in 1936 as scleroderma, later renamed SSc. New classification criteria for this disease issued in 2013 now allow for a diagnosis to be confirmed. Important for this process, however, is the question of whether or not Klee's hands were affected by his illness. The morphology of the artist's hands and evidence of dysgraphic changes in his handwriting are reviewed as indications of his manual pathology. Despite his illness, Klee triumphed over his infirmity, simplifying his painting and drawing styles and substantially increasing his artistic output from 1936 until his death in 1940. PMID:25236296

His ,,phagocytic theory" is the principle of immunological concept "self and not self" as the prerequisition of physiological inflammation, and selfmaintaining of organism. Ehrlich developed the methods for standardization of antibody activity in immune sera, described neutralizing and complement-depending effect of antibodies and enunciated the ,"ide-chain" theory of the formation of antibodies. Their concept of the key-stone of immunity was different, but they expressed the basic paradigma of immunology: immunity imply the protection of identity and guarantee the integrity of organism.

    We demonstrate that abundant quantities of short-lived beta unstable ions can be trapped in a novel transparent Paul trap and that their decay products can directly be detected in coincidence. Low energy 6He+ (807 ms half-life) ions were extracted from the SPIRAL source at GANIL, then decelerated, cooled, and bunched by means of the buffer gas cooling technique. More than 10(8) ions have been stored over a measuring period of six days, and about 10(5) decay coincidences between the beta particles and the 6Li++ recoiling ions have been recorded. The technique can be extended to other short-lived species, opening new possibilities for trap assisted decay experiments.

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

    First principles, density functional theory (DFT) modelling of the oxygen reduction reaction (ORR) on noble metal (Pt, Au, Pd), Pt3M (M = Fe, Co, Ni, Cu) and Pd3M (M = Fe, Co, Ni, Cu) alloy surfaces, was carried out. Periodic models of close-packed (111) surfaces were constructed, their geometry was optimized and the most stable geometric surface configuration was identified. The correlation between the intermediate species binding energy and the favored reaction pathway from amongst 1e-, 2e-, and 4e- mechanisms were studied by calculating the binding energies of a 1/4 monolayer of O, O2, LiO, LiO2, Li2O2, and Li2O on various sites and orientations. The reaction free energies (ΔGrxn) were calculated and used to compute the catalytic activity of the surfaces using molecular kinetics theory. Plots of the catalytic activity vs. Oxygen binding energy (EBinding (O)) showed a typical "volcano" profile. The insights gained from this study can be used to guide the choice of cathode catalysts in Lisbnd O2 cells.

    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

    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

    This note presents the results of a series of tests made in the N.A.C.A. tank on a one-sixth full-size model of the hull and side floats of the Navy P3M-1 flying boat for the purpose of finding a method of reducing the amount of spray thrown into the propellers of this craft when taking off and landing. The model was tested without spray strips and with five different spray-strip arrangements. The best arrangement was an improvement over the bare hull with no spray strips, but the improvement was not sufficient to be satisfactory with the propellers in the designed position.

    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.

    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.

    The beamline BL7B at the UVSOR facility for solid-state spectroscopy is currently under reconstruction. This reconstruction mainly involves the replacement of the 1 m Seya-Namioka-type monochromator (50-600 nm) with a 3 m NIM (modified version of McPherson model 2253), which covers the 50-1000 nm range with three gratings. The deviation angle of the gratings is 15 degrees. For linear and circular polarization experiments, the beamline optics consist of a two-grazing-incidence (87.5 degrees ) pre-mirror system and a normal-incidence (15 degrees ) post-mirror.

    We have designed a new kind of focal reducer for the 2.3 m Thai National Telescope (TNT) to image the TNT specified FOV Δθ = 14.6' with an angular resolution α ≈1.2 arcsec. This, at a minimum cost by using common glasses, spherical surfaces and by requiring comfortable mechanical tolerance. This focal reducer comprises 1 lens placed at the level of the fork entrance and 1 lens placed in front of the detector. In this paper, we present the focal reducer paraxial model, we describe the optical design and we present the performance.

    2013-04-01

    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.

    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.

    1989-10-01

    Since the 1950s, government officials on St. Lucia, a beautiful volcanic island at the southern end of the Eastern Caribbean, have entertained prospects of developing geothermal power. After years of study jointly funded by St. Lucia, USAID, and UNRFNRE (United Nations Revolving Fund for Natural Resources Exploration) in the first half of this decade, a promising 4,636 foot deep exploratory well, SL-2 at Sulfur Springs, was completed in February 1988. Preliminary indications suggest that well could produce about 5 MW of power, though progress to develop the resource appears stalled. Growth has strained the capacity of growing, St. Lucia Electricity Services (LUCELEC), which controls electrical power generation and distribution on the island. Government planners realize that expanding their electric power infrastructure is a necessary prerequisite for continued economic development on this island of 238 square miles and consequently view geothermal for the island's baseload demand with diesel handling peaking requirements. As approved investment proposals fuel economic development, they expect energy demand to rise.

  19. Paul Fritts and company, organ builders: The evolution of the mechanical-action organ in the United States during the 20th century with historical emphasis on the instruments of Paul Fritts

    NASA Astrophysics Data System (ADS)

    Still, Tamara G.

    Paul Fritts is known internationally as a builder of mechanical-action pipe organs based on historical models of the 17th and 18 th centuries. He is one of a number of contemporary builders who have researched renaissance and baroque organs as a point of departure for their designs. As builders have returned to antique models to inform their craft, they have debated the importance of certain aspects of classical design. Included here is discussion of some aspects of design with regard to Fritts and other important mechanical-action organbuilders. Topics of discussion include the significance of pipe metals, temperaments and tunings, key action and case design. Some of the professional debate is scientific, other is subjective and very emotional. This dissertation explores the work of Paul Fritts and chronicles his contribution. Biographical information is included.

  20. Two chicken erythrocyte band 3 mRNAs are generated by alternative transcriptional initiation and differential RNA splicing.

    PubMed Central

    Kim, H R; Kennedy, B S; Engel, J D

    1989-01-01

    The erythrocyte anion transport protein (band 3) mediates two distinct cellular functions: it provides plasma membrane attachment sites for the erythroid cytoskeletal network, and it also functions as the anion transporter between the erythrocyte cytoplasm and extracellular milieu. We previously showed that two chicken band 3 polypeptides are encoded by two different mRNAs with different translation initiation sites. Here we show that these two band 3 mRNAs are transcribed from two separate promoters within a single gene. In addition, the two pre-mRNAs are differentially spliced, leading to fusion with coding exons used in common in the two mRNAs. The chicken erythrocyte band 3 gene is therefore the first example of a gene that has two promoters within a single locus which function equally efficiently in one cell type at the same developmental stage.
