    The objective of this Class III project is to demonstrate that detailed reservoir characterization of clastic reservoirs in basinal sandstones of the Delaware Mountain Group in the Delaware Basin of West Texas and New Mexico is a cost-effective way to recover more of the original oil in place by strategic infill-well placement and geologically based field development. The study focused on Geraldine Ford field, which produces from the upper Bell Canyon formation (Ramsey sandstone). Petrophysical characterization of the Ford Geraldine unit was accomplished by integrating core and log data and quantifying petrophysical properties from wireline logs. The petrophysical data were used to map porosity, permeability, net pay, water saturation, mobile oil saturation, and other reservoir properties. Once the reservoir-characterization study was completed, a demonstration area of approximately 1 mi{sup 2} in the northern part of the unit was chosen for reservoir modeling/simulation. A quarter of a five-spot injection pattern in the demonstration area was selected for flow simulations, and two cases of permeability distribution were considered, one using stochastic permeability distribution generated by conditional simulation and the other using layered permeabilities. Flow simulations were performed using UTCOMP, an isothermal, three-dimensional, compositional simulator for miscible gas flooding. Results indicate that 10--30% (1 to 3 MMbbl) of remaining oil in place in the demonstration area can be produced by CO{sub 2} injection.

  2. Jack Reeves and his science. (United States)

    Moore, Lorna G; Grover, Robert F


    John T. (Jack) Reeves' science is reviewed across the 37 years of his research career at the University of Colorado Health Sciences Center, a period which occupied approximately half his remarkable life. His contributions centered on understanding the inter-relatedness as well as the underlying mechanisms controlling the various components of the O(2) transport system. We review here his studies on exercise performance; these encompassed about half his scientific output with the other half being devoted to the study of hypoxic pulmonary hypertension. Early studies concerned cardiac output, showing how it was a balance between O(2) uptake and O(2) extraction, and that cardiac output during exercise at high altitude was reduced, most likely because of decreased plasma volume and left ventricular filling. Jack's many studies addressed virtually every aspect of the O(2) transport system -- adding significantly to our understanding of the syndromes of altitude illness, the mechanisms by which ventilatory sensitivity to hypoxia and hypercapnia influenced ventilatory acclimatization, and the contributions of the various limbs of the autonomic nervous system on systemic blood pressure, vascular resistance and substrate utilization. His scientific career ended abruptly in 2004 when struck by a car while biking to work, but his legacy remains in his more than 385+ research articles or chapters, the 40+ fellows he trained, and the countless number of younger (and older) scientists for whom he served as a role model for learning how to scrutinize their data and present their findings in clear and sometimes bold prose. An integral man, he is sorely missed.

  3. Epigene and Hypogene Gypsum Karst Manifestations of the Castile Formation: Eddy County, New Mexico and Culberson County, Texas, USA

    Stafford Kevin W.


    Full Text Available Permian evaporites of the Castile Formation crop out over ~1,800 km2 in the western Delaware Basin (Eddy County, New Mexico and Culberson County, Texas, USA with abundant and diverse karst manifestations. Epigene karst occurs as well-developed karren on exposed bedrock, while sinkholes dominate the erosional landscape, including both solutional and collapse forms. Sinkhole analyses suggest that more than half of all sinks are the result of upward stoping of subsurface voids, while many solutional sinks are commonly the result of overprinting of collapsed forms. Epigene caves are laterally limited with rapid aperture decreases away from insurgence, with passages developed along fractures and anticline fold axes. Hypogene karst occurs as diverse manifestations, forming the deepest and longest caves within the region as well as abundant zones of brecciation. Hypogene caves exhibit a wide range of morphologies from complex maze and anastomotic patterns to simple, steeply dipping patterns, but all hypogene caves exhibit morphologic features (i.e. risers, outlet cupolas and half-tubes that provide a definitive suite of evidence of dissolution within a mixed convection (forced and free convection hydrologic system. Extensive blanket breccias, abundant breccia pipes and numerous occurrences of calcitized evaporites indicate widespread hypogene speleogenesis throughout the entire Castile Formation. Although most cave and karst development within the Castile outcrop region appears to have hypogene origins, epigene processes areactively overprinting features, creating a complex speleogenetic evolution within the Castile Formation.

    CERN Document Server


    THURSDAY 15 NOVEMBER 2007 at 8.00 p.m. CERN, Globe of Science and Innovation, Route de Meyrin, 1211 Geneva Our planet is unwell, as witnessed by global warming, the exhaustion of natural resources, soil and water pollution, the uneven distribution of wealth, human malnutrition, the extinction of species, etc. Is the situation really so dire? What should we make of the theories that challenge this pessimism? Hubert Reeves will review the threats facing our planet in detail, based on the most credible scientific data available - and the associated uncertainties - and conclude that it is not life on Earth but the future of the human race that is in danger. Is the fate of mankind, whose origins go back millions of years, to be decided in the space of a few decades? Our future is in our own hands. We must act before it’s too late.

    Shi, Yaohua; Guo, Ximing; Gu, Zhifeng; Wang, Aimin; Wang, Yan


    Haliotis diversicolor Reeve is one of the most important mollusks cultured in South China. Preliminary genetic linkage maps were constructed with amplified fragment length polymorphism (AFLP) markers. A total of 2 596 AFLP markers were obtained from 28 primer combinations in two parents and 78 offsprings. Among them, 412 markers (15.9%) were polymorphic and segregated in the mapping family. Chi-square tests showed that 151 (84.4%) markers segregated according to the expected 1:1 Mendelian ratio ( P<0.05) in the female parent, and 200 (85.8%) in the male parent. For the female map, 179 markers were used for linkage analysis and 90 markers were assigned to 17 linkage groups with an average interval length of 25.7 cm. For the male map, 233 markers were used and 94 were mapped into 18 linkage groups, with an average interval of 25.0 cm. The estimated genome length was 2 773.0 cm for the female and 2 817.1 cm for the male map. The observed length of the linkage map was 1 875.2 cm and 1 896.5 cm for the female and male maps, respectively. When doublets were considered, the map length increased to 2 152.8 cm for the female and 2 032.7 cm for the male map, corresponding to genome coverage of 77.6% and 72.2%, respectively.

    Full Text Available The family Amplullaridae belongs to this class Gastropoda and is made up of freshwater organisms with a wide geographical distribution in tropical regions. Oligochaeta worms can be found in association with snails of this family, inhabiting the umbilicus of their shells. Due to the lack of information on the ecology of these worms, this work focused on investigating which kind of Oligochaeta species associate with the mollusk Pomacea bridgesii (Reeve, 1856. Samples were collected during winter and spring 2003 and summer 2004. From a total of 209 snails collected, the presence of Oligochaeta worms was observed in only 58 of them (27.75%. In these infected snails, 89 Oligochaeta worms were found, all belonging to the family Naididae. The species Haemonais waldvogeli Bretscher, 1900, Dero (Dero nivea Aiyer, 1929 and Dero (Dero sawayai Marcus, 1943 were the most abundant (43.68%, 12.32% and 10.08%, respectively. Haemonais waldvogeli was found in all of the seasons studied, what demonstrates its affinity for this kind of substrate. The results indicate that several Naididae species find in the umbilicus of these snails's shells (which contains fine detritus a favorable habitat for establishing themselves.A família Ampullaridae, pertencente à classe Gastropoda, é caracterizada por organismos de água doce com ampla distribuição na região tropical.

    Hankin and Reeves' (1988) approach to estimating fish abundance in small streams has been applied in stream fish studies across North America. However, their population estimator relies on two key assumptions: (1) removal estimates are equal to the true numbers of fish, and (2) removal estimates are highly correlated with snorkel counts within a subset of sampled...

  9. Molecular evidence for piroplasms in wild Reeves' muntjac (Muntiacus reevesi) in China. (United States)

    Yang, Ji-fei; Li, You-quan; Liu, Zhi-jie; Liu, Jun-long; Guan, Gui-quan; Chen, Ze; Luo, Jian-xun; Wang, Xiao-long; Yin, Hong


    DNA from liver samples of 17 free-ranging wild Reeves' muntjac (Muntiacus reevesi) was used for PCR amplification of piropalsm 18S rRNA gene. Of 17 samples, 14 (82.4%) showed a specific PCR product which were cloned and sequenced. BLAST analysis of the sequences obtained showed similarities to Babesia sp., Theileria capreoli, Theileria uilenbergi and Theileria sp. BO302-SE. Phylogenetic analysis showed that the Babesia sp. detected in the present study was distantly separated from known Babesia species of wild and domestic animals. Six sequences showed 100% similarity to T. capreoli while five sequences were separated from all known Theileria species and constituted an independent clade with Theileria sp. BO302-SE derived from roe deer in Italy; two sequences were close to T. uilenbergi with 97% similarity. This is the first description of hemoparasite infection in free-ranging wild Reeves' muntjac in China. Our results indicate that wild Reeves' muntjac may play an important reservoir role for hemoparasites. Crown Copyright © 2014. Published by Elsevier Ireland Ltd. All rights reserved.

  10. Hankin and Reeves' approach to estimating fish abundance in small streams: limitations and potential options; TOPICAL

    Thompson, William L.


    Hankin and Reeves' (1988) approach to estimating fish abundance in small streams has been applied in stream-fish studies across North America. However, as with any method of population estimation, there are important assumptions that must be met for estimates to be minimally biased and reasonably precise. Consequently, I investigated effects of various levels of departure from these assumptions via simulation based on results from an example application in Hankin and Reeves (1988) and a spatially clustered population. Coverage of 95% confidence intervals averaged about 5% less than nominal when removal estimates equaled true numbers within sampling units, but averaged 62% - 86% less than nominal when they did not, with the exception where detection probabilities of individuals were and gt;0.85 and constant across sampling units (95% confidence interval coverage= 90%). True total abundances averaged far (20% - 41%) below the lower confidence limit when not included within intervals, which implies large negative bias. Further, average coefficient of variation was about 1.5 times higher when removal estimates did not equal true numbers within sampling units (C(bar V)0.27[SE= 0.0004]) than when they did (C(bar V)= 0.19[SE= 0.0002]). A potential modification to Hankin and Reeves' approach is to include environmental covariates that affect detection rates of fish into the removal model or other mark-recapture model. A potential alternative is to use snorkeling in combination with line transect sampling to estimate fish densities. Regardless of the method of population estimation, a pilot study should be conducted to validate the enumeration method, which requires a known (or nearly so) population of fish to serve as a benchmark to evaluate bias and precision of population estimates

    Wanto, Anjar; Zarlis, Muhammad; Sawaluddin; Hartama, Dedy


    Backpropagation is a good artificial neural network algorithm used to predict, one of which is to predict the rate of Consumer Price Index (CPI) based on the foodstuff sector. While conjugate gradient fletcher reeves is a suitable optimization method when juxtaposed with backpropagation method, because this method can shorten iteration without reducing the quality of training and testing result. Consumer Price Index (CPI) data that will be predicted to come from the Central Statistics Agency (BPS) Pematangsiantar. The results of this study will be expected to contribute to the government in making policies to improve economic growth. In this study, the data obtained will be processed by conducting training and testing with artificial neural network backpropagation by using parameter learning rate 0,01 and target error minimum that is 0.001-0,09. The training network is built with binary and bipolar sigmoid activation functions. After the results with backpropagation are obtained, it will then be optimized using the conjugate gradient fletcher reeves method by conducting the same training and testing based on 5 predefined network architectures. The result, the method used can increase the speed and accuracy result.

    This report describes the diagnosis and management of idiopathic epilepsy in a 4-yr-old intact female Reeve's muntjac ( Muntiacus reevesi). The patient was initially witnessed to have isolated paroxysmal events consistent with epileptic seizures (altered consciousness, lateral recumbency, tonic/clonic movement of limbs) lasting less than 3 min with an immediate return to normal consciousness. The seizure frequency increased to >3 seizures within 24 hr and phenobarbital 3 mg/kg orally every 12 hr was started. Because of continued epileptic seizures and low serum phenobarbital levels, the dose was increased until significant elevations of aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were detected. Levetiracetam 40 mg/kg orally every 12 hr was initiated and the phenobarbital was weaned and discontinued. One breakthrough seizure has been witnessed in the 10 mo since starting levetiracetam.

  19. Mother to offspring transmission of chronic wasting disease in reeves' muntjac deer.

    Directory of Open Access Journals (Sweden)

    Amy V Nalls

    Full Text Available The horizontal transmission of prion diseases has been well characterized in bovine spongiform encephalopathy (BSE, chronic wasting disease (CWD of deer and elk and scrapie of sheep, and has been regarded as the primary mode of transmission. Few studies have monitored the possibility of vertical transmission occurring within an infected mother during pregnancy. To study the potential for and pathway of vertical transmission of CWD in the native cervid species, we used a small cervid model-the polyestrous breeding, indoor maintainable, Reeves' muntjac deer-and determined that the susceptibility and pathogenesis of CWD in these deer reproduce that in native mule and white-tailed deer. Moreover, we demonstrate here that CWD prions are transmitted from doe to fawn. Maternal CWD infection also appears to result in lower percentage of live birth offspring. In addition, evolving evidence from protein misfolding cyclic amplification (PMCA assays on fetal tissues suggest that covert prion infection occurs in utero. Overall, our findings demonstrate that transmission of prions from mother to offspring can occur, and may be underestimated for all prion diseases.

  20. Fletcher-Reeves based Particle Swarm Optimization for prediction of molecular structure. (United States)

    Agrawal, Shikha; Silakari, Sanjay


    The determination of the most stable conformers of a molecule can be formulated as a global optimization problem. Knowing the stable conformers of a molecule is important because it allows us to understand its properties and behavior based on its structure. The most stable conformation is that involving the global minimum of potential energy. The problem of finding this global minimum is highly complex, and is computationally difficult because of the number of local minima, which grows exponentially with molecular size. In this paper, we propose a hybrid approach combining Particle Swarm Optimization (PSO) and the Fletcher-Reeves algorithm to minimize the potential energy function. The proposed hybrid algorithm is applied to a simplified molecular potential energy function in problems with up to 100 degrees of freedom and also to a realistic potential energy function modeling a pseudoethane molecule. The computational results for both the cases show that the proposed method performs significantly better than the other algorithms. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available In recent years, a large number of concepts for drive train electrification and a corresponding broad variety of available drive train configurations were presented to the public. They all have their pros and cons for the customer. This paper discusses a tool enabling the customer to select the drive train which is best suited to his individual purposes. The presented approach focuses on BEV and REEV and is characterized by a three-step procedure: the customer’s individual driving behaviour is measured: individualized driving cycles and operational habits including the daily kilometrage are derived; numerical models of the alternative drive train concepts are run to simulate the energy consumption by applying these individualized cycles. The study reveals that battery sizing is the most important component. It would be more efficient to use a REEV with a smaller battery instead of a BEV: at a given range of 50 km the BEV covers 50% of the kilometers (corresponding to 90% of all daily distances while the REEV covers 100% of all daily distances, out of it 70% on electric driving. This leads to less CO2 emission compared to the combined use of BEV and conventional cars. The REEV with the smallest battery is amortized first referred to conventional cars. The influence of the individual usage pattern can be translated to operational costs. The REEV urban driver covers 85% by electric driving and has thus lower operational costs than the REEV inter-urban driver with 64% electric driving.

  5. Hydrologic interpretation of geophysical data from the southeastern Hueco Bolson, El Paso, and Hudspeth Counties, Texas (United States)

    Gates, Joseph Spencer; Stanley, W.D.


    Airborne-electromagnetic and earth-resistivity surveys were used to explore for fresh ground water in the Hueco Bolson southeast of El Paso, Texas. Aerial surveys were made along about 500 miles (800 km) of flight line, and 67 resistivity soundings were made along 110 miles (180 km) of profile. The surveys did not indicate the presence of any large bodies of fresh ground water, but several areas may be underlain by small to moderate amounts of fresh to slightly saline water.The material underlying the flood plain of the Rio Grande is predominantly clay or sand of low resistivity. Along a band on the mesa next to and parallel to the flood plain, more resistive material composed partly of deposits of an ancient river channel extends to depths of about 400 to 1,700 feet (120 to 520 m). Locally, the lower part of this more resistive material is saturated with fresh to slightly saline water. The largest body of fresh to slightly saline ground water detected in this study is between Fabens and Tornillo, Texas, mostly in the sandhill area between the flood plain and the mesa. Under assumed conditions, the total amount of water in storage may be as much as 400,000 to 800,000 acre-feet (500 million to 1 billion m ).The resistivity data indicate that the deep artesian zone southwest of Fabens extends from a depth of about 1,200 feet (365 m) to about 2,800 feet (855 m).

  6. A Unique Yttrofluorite-Hosted Giant Heavy Rare Earth Deposit: Round Top Mountain, Hudspeth County, Texas, USA (United States)

    Pingitore, N. E.; Clague, J. W.; Gorski, D.


    Round Top Mountain is a surface-exposed peraluminous rhyolite laccolith, enriched in heavy rare earth elements, as well as niobium-tantalum, beryllium, lithium, fluorine, tin, rubidium, thorium, and uranium. The extreme extent of the deposit (diameter one mile) makes it a target for recovery of valuable yttrium and HREEs, and possibly other scarce elements. The Texas Bureau of Economic Geology estimated the laccolith mass as at least 1.6 billion tons. A Preliminary Economic Assessment for Texas Rare Earth Resources listed an inferred mineral resource of 430,598,000 kg REOs (rare earth oxides), with over 70% Y+HREEs (YHREE). Put in global perspective, China is thought to produce ~25,000 tons YHREE per year, and exports but a small fraction of that. Because of the extremely fine grain size of the late-phase fluorine-carried critical fluid mineralization, it has not been clear which minerals host the YHREEs. X-ray Absorption Spectroscopy experiments at the Stanford Synchrotron Radiation Lightsource revealed that virtually all of the YHREE content resides in yttrofluorite, rather than in the other reported REE minerals in the deposit, bastnaesite and xenotime. The extended x-ray absorption fine structure (XAFS) spectra of the sample suite were all quite similar, and proved a close match to known model compound specimens of yttrofluorite from two locations, in Sweden and New Mexico. Small spectral variation between the two model compounds and among the samples is attributable to the variable elemental composition and altervalent substitutional nature of yttrofluorite (Ca [1-x] Y,REE [x])F[2+x]. We found no other reported deposit in the world in which yttrofluorite is the exclusive, or even more than a minor, YHREE host mineral. Leaching experiments show that the YHREEs are easily liberated by dissolution with dilute sulfuric acid, due to the solubility of yttrofluorite. Flotation separation of the yttrofluorite had been demonstrated, but was rendered inefficient by the micron-scale grain size of the yttrofluorite. Our laboratory leaching experiments with different acid strengths, grain sizes, and exposure times showed up to 90% recovery of the YHREEs. As expected, similar recoveries were obtained from longer exposure times at lower sulfuric acid concentration. Optimal grain size is in the 2-10 mm range. Thus a heap leach of the deposit is likely feasible, aided by the fact that 90-95% of the rock comprises insoluble and unreactive quartz and feldspars. The absence of overburden, proximity (a few km) to an interstate highway and major rail systems, temperate climate, and favorable political location enhance the potential and appeal for development of a heap leach operation. The grade of the deposit is just over 0.05% total rare earth elements plus yttrium. Although some might consider this sub-economic, it is in the range of the South China ionic clay deposits that supply essentially all of the world's YHREEs. Further, the grade is remarkably consistent through 1657 samples from 64 reverse-circulation drill holes with a total sampled interval of 30,353 feet. This consistency of grade permits accurate economic assessment and prediction, an unchanging ore grade and mine feedstock over life of mine, and a single REE separation chemistry to be developed. Thus mine and separation procedures need only be developed and optimized once.

  7. Remote Sensing Analysis of the Sierra Blanca (Faskin Ranch) Low-Level Radioactive Waste Disposal Site, Hudspeth County, Texas

    Remote sensing images provide useful physical information, revealing such features as geological structure, vegetation, drainage patterns, and variations in consolidated and unconsolidated lithologies. That technology has been applied to the failed Sierra Blanca (Faskin Ranch) shallow burial low-level radioactive waste disposal site selected by the Texas Low-Level Radioactive Waste Disposal Authority. It has been re-examined using data from LANDSAT satellite series. The comparison of the earlier LANDSAT V (5/20/86) (30-m resolution) with the later new, higher resolution ETM imagery (10/23/99) LANDSAT VII data (15-m resolution) clearly shows the superiority of the LANDSAT VII data. The search for surficial indications of evidence of fatal flaws at the Sierra Blanca site utilizing was not successful, as it had been in the case of the earlier remote sensing analysis of the failed Fort Hancock site utilizing LANDSAT V data. The authors conclude that the tectonic activity at the Sierra Blanca site is much less recent and active than in the previously studied Fort Hancock site. The Sierra Blanca site failed primarily on the further needed documentation concerning a subsurface fault underneath the site and environmental justice issues. The presence of this fault was not revealed using the newer LANDSAT VII data. Despite this fact, it must be remembered that remote sensing provides baseline documentation for determining future physical and financial remediation responsibilities. On the basis of the two sites examined by LANDSAT remote sensing imaging, it is concluded that it is an essential, cost-effective tool that should be utilized not only in site examination but also in all nuclear-related facilities

  8. Structural constraints for proposed Fort Hancock low-level radioactive waste disposal site (NTP-S34), southern Hudspeth County, Texas

    International Nuclear Information System (INIS)

    Lemone, D.V.


    Structural complexities reduce the homogeneity necessary for a site characterization model to an unacceptable level for performance assessment for radioactive waste disposal sites. The proposed site lies between the northern, stable Diablo platform and the southern, mobile Mesozoic Chihuahua tectonic belt. Structural movement along this interface has been active for the past 14,000 years. In addition, the area lies along the northern margin of the Permian Marfa basin and the northeastern margin of the deeply faulted Hueco bolson segment of the late Cenozoic Rio Grande rift system. Recent seismic activity with extensive surface rupture in Quitman Canyon (30 mi southeast of the site) is also documented from the 1931 Valentine, Texas, earthquake (6.4 Richter scale). The site is underlain by either a thrust fault or the complex terminus of a Mesozoic thrust fault. This fault is a segment of the continuous thrust sheet extending from exposures in the Sierra Blanc area, 30 mi east (Devil Ridge fault), to the El Paso area west (Rio Grande fault). This segment of the Devil Ridge-Rio Grande thrust is documented by the Haymond Krupp No. 1 Thaxton wildcat drilled at Campogrande Mountain immediately south of the site. The recent rift fault scarp (Campo Grande) immediately south of the Thaxton well has a 17-mi surface trace and is, no doubt, related to the subsurface Clint fault to the west in the El Paso area. An additional complexity is the presence of a monoclinal flexure with a minimum of 900 ft of surface relief (2 mi northeast of NTP-S34). A 4.5-mi, east-west, down-to-the-south normal fault occurs near the top of the monocline with a small associated graben. These complexities seriously compromise the proposed Fort Hancock site

  9. Mortality estimate of Chinese mystery snail, Bellamya chinensis (Reeve, 1863) in a Nebraska reservoir (United States)

    Haak, Danielle M.; Chaine, Noelle M.; Stephen, Bruce J.; Wong, Alec; Allen, Craig R.


    The Chinese mystery snail (Bellamya chinensis) is an aquatic invasive species found throughout the USA. Little is known about this species’ life history or ecology, and only one population estimate has been published, for Wild Plum Lake in southeast Nebraska. A recent die-off event occurred at this same reservoir and we present a mortality estimate for this B. chinensis population using a quadrat approach. Assuming uniform distribution throughout the newly-exposed lake bed (20,900 m2), we estimate 42,845 individuals died during this event, amounting to approximately 17% of the previously-estimated population size of 253,570. Assuming uniform distribution throughout all previously-reported available habitat (48,525 m2), we estimate 99,476 individuals died, comprising 39% of the previously-reported adult population. The die-off occurred during an extreme drought event, which was coincident with abnormally hot weather. However, the exact reason of the die-off is still unclear. More monitoring of the population dynamics of B. chinensis is necessary to further our understanding of this species’ ecology.

    Dutton, Shirley P.; Flanders, William A.; Guzman, Jose I.; Zirczy, Helena


    The objective of this Class III project is to demonstrate that detailed reservoir characterization of slope and basin clastic reservoirs in sandstones of the Delaware Mountain Group in the Delaware Basin of West Texas and New Mexico is a cost-effective way to recover a higher percentage of the original oil in place through geologically based field development. The project focused on reservoir characterization of the East Ford unit, a representative Delaware Mountain Group field that produces from the upper Bell Canyon Formation (Ramsey Sandstone). The field, discovered in 1960, is operated by Oral Petco, Inc., as the East Ford unit: it contained an estimated 18.4 million barrels (MMbbl) of original oil in place.

  13. Evolution of Conus Peptide Toxins: Analysis of Conus californicus Reeve, 1844 (United States)

    Biggs, Jason S.; Watkins, Maren; Puillandre, Nicolas; Ownby, John-Paul; Lopez-Vera, Estuardo; Christensen, Sean; Moreno, Karla Juarez; Navarro, Alexei Licea; Corneli, Patrice Showers; Olivera, Baldomero M.


    Conus species are characterized by their hyperdiverse toxins, encoded by a few gene superfamilies. Our phylogenies of the genus, based on mitochondrial genes, confirm previous results that C. californicus is highly divergent from all other species. Genetic and biochemical analysis of their venom peptides comprise the fifteen most abundant conopeptides and over 50 mature cDNA transcripts from the venom duct. Although C. californicus venom retains many of the general properties of other Conus species, they share only half of the toxin gene superfamilies found in other Conus species. Thus, in these two lineages, approximately half of the rapidly diversifying gene superfamilies originated after an early Tertiary split. Such results demonstrate that, unlike endogenously acting gene families, these genes are likely to be significantly more restricted in their phylogenetic distribution. In concordance with the evolutionary duistance of C. californicus from other species, there are aspects of prey-capture behavior and prey preferences of this species that diverges significantly from all other Conus.

    Full Text Available Pengamatan pertumbuhan dan reproduksi abalon Haliotis squamata dilakukan di hatcheri Balai Besar Riset Budidaya Laut dan Penyuluhan Perikanan (BBRBLPP Gondol, Bali. Tujuan dari penelitian ini untuk memperoleh informasi tentang keragaan pertumbuhan dan performansi reproduksi abalon turunan ketiga. Induk H. squamata turunan kedua hasil seleksi yang digunakan untuk menghasilkan benih turunan ketiga mempunyai ukuran panjang cangkang 6,5-7,0 cm. Benih dipelihara dalam bak beton berukuran 2,5 m x 1,2 m x 1,0 m yang diberikan feeding plate sebagai substrat penempelan dan dilengkapi dengan sistem aerasi dan sistem air mengalir. Pakan yang diberikan pada awal pemeliharaan adalah diatom jenis Nitzschia sp. dan Melosira sp. yang telah ditumbuhkan terlebih dahulu pada feeding plate sebelum penebaran benih. Benih F-3 dipelihara sampai menjadi calon induk untuk diamati perkembangan reproduksinya. Pengambilan sampel pertumbuhan dilakukan setiap 10 hari. Pengamatan reproduksi dilakukan pada saat abalon mulai tumbuh gonad sampai matang gonad stadia-III. Hasil penelitian menunjukkan bahwa pertumbuhan abalon sangat dipengaruhi ketersediaan pakan pada plate terutama pada hari ke-50. Proporsi jantan-betina abalon F-3 (3,3:1 meningkat dibandingkan dengan F-0 dari alam (2,5:1 menunjukkan ketidakseimbangan jumlah individu yang dapat disebabkan oleh tekanan seleksi.

Observation on the growth and reproduction development of Haliotis squamata had been undertaken in the hatchery of the Institute for Mariculture Research and Development (IMRAD Gondol, Bali. The research was aimed to study of the growth and reproduction performance of filial-3 abalone in supporting seed production in hatchery. Larvae were obtained from natural spawning of filial-2 abalone broodstock with the length shell of 6.5-7.0 cm in the hatchery. Larvae were reared in 2.5 m x 1.2 m x 1.0 m concrete tank with aeration and water circulation system. Larval samples were taken every 10 days. Larvae were fed with diatom Nitzschia sp. and Melosira sp. Diatom were grown in the feeding plate before the stocking of abalone larvae. Gonadal development of F-3 abalone was observed from the beginning of the study until the mature gonad of stage-III. The result showed that the abalone growth was greatly influenced by the availability of feed in the plate especially at day 50. Abalone F-3 of sixteen months old reached maturity stage earlier compared to the control. The proportion of male-female of F-3 generation (3.3:1 was higher compared to F-0 (2.5:1, indicated the imbalance in the number of individuals that could be caused by selection pressures. These results suggest that sixteen months old abalones could be used as broodstocks for seed production in hatchery.

    The objective of this project is to demonstrate that detailed reservoir characterization of slope and basin clastic reservoirs in sandstones of the Delaware Mountain Group in the Delaware Basin of West Texas and New Mexico is a cost-effective way to recover a higher percentage of the original oil in place through strategic placement of infill wells and geologically based field development. This project involves reservoir characterization of two Late Permian slope and basin clastic reservoirs in the Delaware Basin, West Texas, followed by a field demonstration in one of the fields. The fields being investigated are Geraldine Ford and Ford West fields in Reeves and Culberson Counties, Texas. Project objectives are divided into two major phases, reservoir characterization and implementation. The objectives of the reservoir characterization phase of the project were to provide a detailed understanding of the architecture and heterogeneity of the two fields, the Ford Geraldine unit and Ford West field. Reservoir characterization utilized 3-D seismic data, high-resolution sequence stratigraphy, subsurface field studies, outcrop characterization, and other techniques. Once reservoir characterized was completed, a pilot area of approximately 1 mi{sup 2} at the northern end of the Ford Geraldine unit was chosen for reservoir simulation. This report summarizes the results of the second year of reservoir characterization.

    Fauzan, M.; Bakti, D.; Susetya, I. E.; Desrita


    High market demand for A. gubernaculum, tends to increase the greater catching capacity so that the decreasing population. The aims of this study were to determine the growth and rate of exploitation of A. gubernaculum in Asahan aquatic. It was conducted for 1 Month 14 Days from October to November 2016. Data analyzed by (Electronic Lenght Frequencys Assesment Tool) ELEFAN I method by using (FAO-ICLARM Fish Stock Assesment Tool) on FiSAT II software. Shells obtained 855 individual. The growth pattern of shells is negative allometric. The range of condition factor was 0.81 - 2.15. The frequency distribution of the A. gubernaculum ranges from 14 to 43 mm, the dominant size group was 20 - 22 mm. The prediction of growth parameter Von Bertalanfy showed that the asimptot length (L∞) is 43.05 mm, the growth coefficient (K) is 1.2/year and the theoretical life (t0) of the A. gubernaculum is -0.12. The total Mortality (Z) of Anadara gubernaculum was 2.121/year. Natural mortality estimation rate (M) was 1.9/year. The exploitation rate of Anadara gubernaculum is 0.1/year.

  17. Biomonitoring approach with mussel Mytilus galloprovincialis (Lmk) and clam Ruditapes philippinarum (Adams and Reeve, 1850) in the Lagoon of Venice. (United States)

    Moschino, Vanessa; Delaney, Eugenia; Meneghetti, Francesca; Ros, Luisa Da


    Transplanted Mytilus galloprovincialis and native Ruditapes philippinarum were deployed in 10 sampling stations with different pollution impact within the Lagoon of Venice to evaluate the temporal variations and the suitability of the following cytochemical and histochemical biomarkers just as indicators of environmental stress: lysosomal membrane stability, lipofuscins, neutral lipids and lysosome to cytoplasm volume ratio. The physiological status of the organisms was also investigated by determining the survival in air capability and the reburrowing rate (clams). The biological parameters were assessed in June and October. Furthermore, for a better definition of the environmental aspects of the study sites, heavy metal, PAH and PCB concentrations were also evaluated in the sediments. As a whole, the biological responses examined in both species from all the sampling sites showed significant differences between the two seasonal campaigns, only lysosomal membrane stability exhibited less variability. Pollutants in sediments generally showed low-intermediate contamination levels, few hotspots persisting mostly in the inner areas of the lagoon, the most influenced by the industrial zone. Transplanted mussels were more responsive than native clams and the biological responses of both species varied temporally. The range of the spatial variability was always narrow and reflected only partially the broader variability shown by the chemical content in the sediments. In this sense, biological responses seemed to be particularly influenced by the high temporal and spatial heterogeneity that characterise the Lagoon of Venice, as well as most of the transitional environments.

    Full Text Available This study was examined to reveal haplotype distribution and phylogenetic relationship using mitochondrial DNA CYTB gene sequences of Reeve’s turtle (Mauremys reevesii of East Asia. CYTB sequences of Reeve’s turtles were divided into 6 haplotypes (Hap01–Hap06. Chinese turtles were found in Hap01, Hap02, Hap04, and Hap05, and Hap01 was the highest frequency of 85.0%. Korean Turtles were found in Hap01, Hap03, Hap04, and Hap05, and Hap03 was the highest frequency of 52.1%. Although there was no haplotype which includes only the CYTB sequence exclusive for Reeve’s turtles of Korea, since no CYTB sequence of China was found in Hap03, it would be possible that Hap03 turtles of Korea are separated from those of China. The haplotypes of Reeve’s turtles of East Asia were monophyletic, which indicated that they had been evolved from a single maternal lineage, but went through local evolution after geographical migration and isolation in East Asia.

  20. Proteomic analysis of muscle between hybrid abalone and parental lines Haliotis gigantea Reeve and Haliotis discus hannai Ino (United States)

    Di, G; Luo, X; You, W; Zhao, J; Kong, X; Ke, C


    To understand the potential molecular mechanism of heterosis, protein expression patterns were compared from hybrids of Haliotis gigantea (G) and Haliotis discus hannai (D) using two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption/ionization time-of-flight/time-of-flight analyses. Expression differences were observed in muscle samples from the four groups with 673±21.0 stained spots for H. discus hannai ♀ × H. discus hannai ♂ (DD), 692±25.6 for H. gigantea ♀ × H. gigantea ♂ (GG), 679±16.2 for H. discus hannai ♀ × H. gigantea ♂ (DG) (F1 hybrid) and 700±19 for H. gigantea ♀ × H. discus hannai ♂ (GD) (F1 hybrid). Different 2-DE image muscle protein spots had a mirrored relationship between purebreds and the F1 hybrid, suggesting that all stained spots in F1 hybrid muscle were on 2-DEs from parents. DD and DG clustered together first, and then clustered with GD, whereas the distance of DD and GG was maximal according to hierarchical cluster analysis. We identified 136 differentially expressed protein spots involved in major biological processes, including energy metabolism and stress response. Most energy metabolism proteins were additive, and stress-induced proteins displayed additivity or over-dominance. In these 136 identified protein spots, hybrid offspring with additivity or over-dominance accounted for 68.38%. Data show that a proteomic approach can provide functional prediction of abalone interspecific hybridization. PMID:25669609

  1. Multi-criteria assessment of energy conversion systems by means of thermodynamic, economic and environmental parameters (United States)

    Becerra Lopez, Humberto Ruben


    High expansion of power demand is expected in the Upper Rio Grande region (El Paso, Hudspeth, Culberson, Jeff Davis, Presidio and Brewster counties) as a result of both electrical demand growth and decommissioning of installed capacity. On the supply side a notable deployment of renewable power technologies can be projected owing to the recent introduction of a new energy policy in Texas, which attempts to reach 10,000 installed-MWe of renewable capacity for 2025. Power generation fueled by natural-gas might consistently expand due to the encouraged use of this fuel. In this context the array of participating technologies can be optimized, which, within a sustainability framework, translates into a multidimensional problem. The solution to the problem is presented through this dissertation in two main parts. The first part solves the thermodynamic-environmental problem through developing a dynamic model to project maximum allowable expansion of technologies. Predetermined alternatives include diverse renewable energy technologies (wind turbine, photovoltaic conversion, hybrid solar thermal parabolic trough, and solid oxide fuel cells), a conventional fossil-fuel technology (natural gas combined-cycle), and a breakthrough fossil-fuel technology (solid oxide fuel cells). The analysis is based on the concept of cumulative exergy consumption, expanded to include abatement of emissions. A Gompertz sigmoid growth is assumed and constrained by both exergetic self-sustenance and regional energy resource availability. This part of the analysis assumes that power demand expansion is met by full deployment of alternative technologies backed up by conventional technology. Results show that through a proper allowance for exergy reinvestment the power demand expansion may be met largely by alternative technologies minimizing the primary resource depletion. The second part of the study makes use of the dynamic model to support a multi-objective optimization routine, where the

  2. PAH (Polycyclic Aromatic Hydrocarbon) bioaccumulation and PAHs/shell weight index in Ruditapes philippinarum (Adams & Reeve, 1850) from the Vallona lagoon (northern Adriatic Sea, NE Italy). (United States)

    Cacciatore, Federica; Bernarello, Valentina; Boscolo Brusà, Rossella; Sesta, Giulio; Franceschini, Gianluca; Maggi, Chiara; Gabellini, Massimo; Lamberti, Clauda Virno


    The Vallona lagoon is a transitional area located in the Po River delta (NE, ITALY) traditionally exploited for Manila clam (Ruditapes philippinarum) farming. During 2007-2008, a pipeline was buried in the middle of the lagoon to connect an off-shore structure to facilities on land. PAH levels were monitored in Manila clams and sediments before, during and after the pipeline construction to assess the impact of the activities through the pattern of distribution of the PAH compounds. PAH bioaccumulation in clams displayed seasonal fluctuations with higher levels in autumnal and wintry surveys than in spring-summer. Principal component analysis applied to PAHs in clams highlighted a petrogenic input during ante operam period and a pyrolytic origin during the burying activities. On the contrary, sediment PAH concentrations resulted quite similar both among sites and periods. Biota-Sediment-Accumulation-Factor values also confirmed that sediments were not the major source of PAH pollution for clams in this study. The welfare of clams was examined through two physiological indices (condition index and survival in air) to check the effects of the activities on a commercial resource. Both physiological indices exhibited seasonal variations connected to natural endogenous and exogenous factors; however survival in air was the most sensitive index in highlighting the effects of the pipeline burying activities. Finally, to ensure that PAH bioavailability assessment was not affected by seasonal variation of soft tissues of molluscs, PAHs/shell weight index was applied. Higher levels of this index were observed before and during the burying activities, whilst, after that, values significantly lowered. Moreover, the normalization enabled us to highlight the PAH uptake from clams in some particular periods and to compare different populations in a long-term biomonitoring program with data obtained from different periods of the year.

  3. Effects of gamma-radiation on eggs of Pomacea Haustrum (Reeve, 1843) from the Pampulha Lake, Belo Horizonte, M. G. (prosobranchia, Pilidae)

    Energy Technology Data Exchange (ETDEWEB)

    Dos Santos Carvalho, O; Milward De Andrade, R; Ricardo C Adriano, A; Mansur Neto, E


    Pomacea haustrum eggs, with less than 24 hours after oviposition in the field, were exposed, in groups, to 500, 1,000, 1,500, 2,000, 2,500, 3,000, 3,500, and 4,000 rad, respectively. As regards the irradiated eggs, only 23.9 percent (1,460) achieved eclosion, whose percentage varied according to the gamma-ray dosage used: 41.6 percent for 500 rad; 35.5 percent for 1,000; 21.1 percent for 1,500; 7.9 percent for 2,000; 4.9 percent for 3,000 and, finally, 0.3 percent for 3,500 rad. The 6 egg-masses (1,500 eggs) irradiated with 2,500 rad as well as the 4 (1,401 eggs) exposed to 4,000 rad did not hatch up to 30 days after exposure to gamma-rays. Hatching, among the irradiated eggs, started 11 to 16 days later, their maximum incubation period having ranged from 14 to 16 days. It has also been observed that both the period of incubation and that of recovery of the eggs not irreversibly damaged by the gamma-rays are proportional to the intensity of radiation. Field and laboratory investigations have shown that the eggs in a same mass do not hatch simultaneously, a period of two or more days having already elapsed between the first and last eclosion.

  16. A Graduate Degree in Library or Information Science Is Required, but not Sufficient, to Enter the Profession. A Review of: Reeves, R., & Hahn, T. (2010. Job advertisements for recent graduates: Advising, curriculum, and job-seeking implications. Journal of Education for Library and Information Science, 51(2, 103-119.

    Directory of Open Access Journals (Sweden)

    Nazi Torabi


    Full Text Available Objective – To analyze the current state of the job market for recent MLS or MLIS graduates.Design – Content analysis of job postings.Setting – Online library or archival job advertisements published between 15 April, 2006 and 10 May, 2009 and collected from two national library publications (American Libraries and Library Journal, two electronic lists (Maryland's iSchool Discussion list and the Archives and Archivists list sponsored by the Society of American Archivists, two Internet job banks ( and, and several local chapters of library and archival organizations in the South Atlantic region of the United States.Subjects – 1,042 online library or archival job advertisements. Salary data were obtained from 401 available online job advertisements.Methods – The methodology for collection and content analysis of job ads was adapted from earlier studies, with slight modification wherever appropriate. The following criteria for selecting the ads were applied:• Ad says "entry-level"• No mention of professional experience• No experience or duties impossible for entry-level librarians to gain• Only ads that required an MLS or MLIS degree from an ALA-accredited institution• Part-time or temporary positions of less than nine months were excluded The authors removed duplicated job postings and identified three major areas of content analysis. Table 1 lists a brief summary of these areas and further sub-categories for each area. The content analysis was performed using a custom Microsoft Access database for data organization and storage and Microsoft Excel spreadsheet for data manipulation. SPSS was used for statistical analysis.Main Results – The two largest represented institution types for library positions were academic (63.6% and public (17.5%. For archival positions, the academic (62.7% and "other" (25.4% institutions rank first and second. When the job ads were broken down into the position types, which were covering a wide range of responsibilities, the greatest numbers of entry-level library positions are found to be public service (52.2% and technical services (23.9% positions. The two largest represented position types in archives are technical services (50.7 % and generalist (40.5%.While average salaries increased slightly over the four years of study, there is a more significant increase in the salaries of positions posted in 2009. The highest average salaries were found to be $43K for archivists working for government and $60K for library positions in the "other" category. In addition, the number of entry-level positions has increased from year to year over this period.Social competencies such as communication, collaboration and team work, and service orientation were the most emphasized traits for novice librarians and archivists. General information technology skills and knowledge of technical services were the most common skills required for both library and archive positions. Overall, the entry-level job postings did not require non-professional experience. However, 13.6% of the library and 18.7% of the archival positions required supervisory experience. Experience with preservation of physical objects and the knowledge of programming and mark-up languages were also common requirements for archives positions. Instructional and reference experience ranks the second and third essential skills for librarians.Conclusion – Based on the research results, a graduate degree in library or information science is required, but not sufficient, to enter the profession. Practical experience, either through internships, co-op programs, or part-time or full-time employment, is essential for new graduates seeking employment, but the majority of postings do not require a subject expertise, second Master’s degree, or knowledge of a foreign language. Since the job content analysis in this study only evaluated broad components of library services and archival operation, it might not provide sufficient data on new trends in the job market for the MLS curriculum review.

  17. A Validity Study of the MWEP Scale in Hong Kong

    Directory of Open Access Journals (Sweden)

    Tsun-Lok Kwong


    Full Text Available This article examines the validity of the Multidimensional Work Ethic Profile, MWEP, in the Hong Kong setting. Purposive quota sampling is adopted to solicit data from a total of 140 respondents with equal gender distribution across seven age groups in Hong Kong. Factor analysis reveals that similarity exists between factor loadings in original MWEP model of Miller, Woehr, and Hudspeth (2002 and the model in the current study with Hong Kong samples. However, the MWEP items in the current study does not map exactly into the seven dimensions proposed by Miller, Woehr, and Hudspeth. The leisure and the morality/ethics dimensions match with the original scale respectively with good and poor reliabilities, but the hard work and wasted time dimensions have intertwined and appeared to be inseparable.

  16. Duval Corporation application study: nuclear process energy from PE-CNSG

    International Nuclear Information System (INIS)


    The technical and economic studies were performed to examine the possible installation of a small, integral pressurized water reactor as an industrial energy source in the Duval Corporation's Frasch Process sulfur mining operation located in Culberson County, Texas. Since this is the first industrial application study attempted for this type of reactor, it has been a learning process on the nuclear plant side as well as the industrial side, particularly in the area of economic analysis. The importance of considering inflationary effects, the significance of plant financing form, and the annualized, after-tax cash flow and incremental rate-of-return methods of comparison in determing energy costs have all been recognized during the course of the study

  2. Benefits of obtaining log data in horizontal wells in the WCSB

    Energy Technology Data Exchange (ETDEWEB)

    Spratt, D. [Reeves Wireline Technologies Ltd., Calgary, AB (Canada)


    A Compact Memory Logging (CML) system developed by Reeves Wireline Technologies was presented. It can be used to obtain log data from horizontal wells to get a better understanding of how to enhance production or completion techniques. The methods that are commonly used to obtain data from horizontal wells include measurement while drilling (MWD), logging while drilling (LWD), wet connect pipe conveyed wireline logging and CML. Each method has its unique benefits that range from information on lithology, rock parameters and fluid interfaces. Reeves has been using wireless pipe conveyed CML over the past two years. The log data includes array induction, dual spaced neutron and photo density porosity, Pe, gamma ray, compensated sonic and hose size caliper. Reeves CML is smaller, easily conveyed and has an unprecedented capability to bend and is considered to be well suited for both newly and previously drilled horizontal wells that require remedial assessment. The tool can be used to determine reservoir quality and boundaries, establish zone structures, or identify fluid interfaces for strategic planning of completions and stimulations. This paper presented examples of logs on some horizontal wells that indicate the value of obtaining log data. Reeves CML is considered to be economically and operationally ideal, particularly since data from the CML includes depth of investigation. 5 figs.

    When prices are sticky, movements in the nominal exchange rate have a direct impact on international relative prices. A relative price misalignment would trigger an adjustment in consumption and employment, and may help to predict future movements in the exchange rate. Although purchasing-power-parity fundamentals, in general, have only weak predictability, currency misalignment may be indicated by price differentials for some goods, which could then have predictive power for subsequent re-ev...

  18. Integrating petroleum and sulfur data to map the Guadalupian-Ochoan (Middle to Upper Permian) Boundary of the Delaware Basis, Trans-Pecos, Texas (United States)

    Dishron, Joseph B.


    The Delaware Basin of the Permian Basin is a classic intra-cratonic basin of West Texas and Southeast New Mexico. Hydrocarbon exploration and production have occurred in the region since the early 1920s, and, as a result, the formations related to these oil and gas reserves have been studied in great detail. Some formations in the Delaware Basin, however, have not been studied in such detail, and this thesis examines one, lesser-known unit that could have economic potential. The Lamar Limestone (Lamar Lime) of the Bell Canyon Formation has commonly been dismissed as a production interval; rather, it has been described as a source and seal rock for the Ramsey Sand of the lower Bell Canyon Formation. However, recent studies found that the Lamar Lime was contributing to production, and it has been described by Trentham (2006) as a potentia "mini Barnett" reservoir. The depths of these deposits are in a range that is ideal for oil accumulation. This study made use of data from wells and test holes drilled in the western Delaware Basin, Culberson County, Texas. Many oil and gas wells have been drilled in the western Delaware Basin, but they are concentrated in the north and east portions of Culberson County. In addition, sulfur wells were drilled in the area in the late 1960s and early 1970s. Analyses of the well logs of these wells and of core and outcrop studies were completed to gain a better understanding of the distribution and economic potential of the Lamar. Both datasets were combined to provide information not readily available in the oil and gas dataset. The Lamar Lime is an excellent marker bed because it underlies thick evaporites. The evaporite sequences are Ochoan in age, and, therefore, the contact of the Lamar Lime (Bell Canyon Formation) and the Castile Formation is the approximate boundary for the Guadalupian-Ochoan Series. The Castile Formation, the Salado Formation, and the Rustler Formation (from oldest to youngest) are the evaporite units that

  19. The social and special effects of siting a low-level radioactive waste disposal facility in rural Texas

    International Nuclear Information System (INIS)

    Murdock, S.H.; Hamm, R.R.


    As part of its assessment of the impacts of a low-level radioactive waste disposal facility in Hudspeth County, the Texas Low-Level Radioactive Waste Disposal Authority (TLLRWDA) sponsored an independent study of the social and special impacts of the facility. These impacts include ''standard'' social impacts (such as impacts on social structures and attitudes, values and perceptions and ''special'' social impacts (such as fear, anxiety, concerns related to equity, the health of future generations, etc.). This paper reports the results of this study. Personal interviews with 71 community leaders and 96 randomly selected county residents were conducted during the summer of 1986. The results suggest that the major concern relates to the contamination of ground water, but that suspicion about the equity of the siting process and about the safe management of wastes is extensive, even among the most knowledgeable respondents. Mitigation concerns center on health and safety issues for residents and on potential forms of mitigation for governmental jurisdictions for leaders. Responses were similar for leaders and residents and for persons in different parts of the county

  20. The Texas concurrent characterization, licensing, and development process

    Energy Technology Data Exchange (ETDEWEB)

    Avant, R.V. Jr. [Texas Low-Level Radioactive Waste Disposal Authority, Austin, TX (United States)


    The 72nd Texas Legislature specifically delineated a 400-square-mile area in southeast Hudspeth County where siting activities would be limited. The Authority was given unprecedented powers of property access and eminent domain and expanded budget authority to conduct site selection, characterization, and licensing. In the summer of 1991, the Authority identified five general siting areas in the prescribed region, and in the fall of 1991, the Authority narrowed the siting area to one large ranch composed of about 16,000 acres--called the Faskin Ranch. Site characterization began in 1991 and will be complete by September 1993. In September 1991, Authority staff began preparing the license application and included all available information on the Faskin Ranch. At its February meeting, the Authority`s board directed staff to submit the license application to the Texas Water Commission (the new Texas radiation control agency). The license application was submitted on March 2, 1992, and on April 15, 1992, the Commission determined that the application was sufficiently complete to begin review. Discrete technical packages such as groundwater hydrology, surface water hydrology, design, etc., will be submitted to the agency for review on the completion of each package. A schedule has been developed to allow the regulators the maximum time possible to review critical technical areas while minimizing the total review period.

  1. Atoms of Silence (United States)

    Reeves, Hubert


    In the grand tradition of popular exposition, astrophysicist Hubert Reeves explains current scientific understanding of the deepest mysteries of the universe in terms that will excite, stimulate, and educate the nonscientific reader. When it was first published in France in 1981, this book quickly became a best-seller and was avidly embraced by the popular press. The reviewer for L'Express, for example, wrote that "Reeves turns astrophysics into an epic saga, a metaphysical fresco, a story in the fullest sense of the word. [He can do this] because he forgets to be a professor. Facing the sky, his eternal home, he recounts the titanic struggle of primordial forces that, over the course of billions of years, formed the cosmos and all it contains...." The book falls into three broad sections. The first explores the implications of the discovery that the universe does indeed have a history - that the night sky that so excites our wonder is not static but has both a beginning and an end. The second uncovers the layers of evolution that comprise that history, from the cosmic phase in the first few moments of the universe when energy first transformed itself into matter, to the biological phase when matter transformed itself into life. The third goes behind the scenes of the universal drama to examine such basic concepts as time, energy, and chance. Reeves' style is metaphorical, determinedly naive, and even slightly anthropomorphic. Music becomes a metaphor for all of the orderliness in the universe that might just as easily have been cosmic "noise" if there had been no guiding principles at work. To understand those guiding principles, and to gain a fuller appreciation of the music that they produce, is` the goal of this enlightening and poetic book. Hubert Reeves was born in Montreal and educated in Canada and the United States. Since 1966 he has been director of research at France's Centre National de la Recherche Scientifique while continuing research at the Centre d

In photoelectron experiments the geometric properties of the parent anion orbital are reflected in the photoelectron angular distribution (PAD), an area of research that has benefited largely from the ability of velocity-map imaging (VMI) to simultaneously record both the energetic and angular information, with 100% collection efficiency. Photoelectron spectra of NO_{2}^{-}, taken over a range of wavelengths (355nm-520nm) with the ANU's VMI spectrometer, reveal an anomalous jump in the anisotropy parameter near threshold. Consequently, the orbital behavior of NO_{2}^{-} appears to be quite different near threshold compared to detachment at higher photon energies. This surprising effect is due to the Wigner Threshold law, which causes p orbital character to dominate the photodetachment cross-section near threshold, before the mixed s/d orbital character becomes significant at higher electron kinetic energies. By extending recent work on binary character models to form a more general expression, the variable mixed orbital character of NO_{2}^{-} is able to be described. This study provides the first multi-wavelength NO_{2} anisotropy data, which is shown to be in decent agreement with much earlier zero-core model predictions of the anisotropy parameter. K. J.

    The objective of this Class III project is to demonstrate that detailed reservoir characterization of clastic reservoirs in basinal sandstones of the Delaware Mountain Group in the Delaware Basin of West Texas and New Mexico is a cost-effective way to recover more of the original oil in place by strategic infill-well placement and geologically based enhanced oil recovery. The study focused on the Ford Geraldine unit, which produces from the upper Bell Canyon Formation (Ramsey sandstone). Reservoirs in this and other Delaware Mountain Group fields have low producibility (average recovery <14 percent of the original oil in place) because of a high degree of vertical and lateral heterogeneity caused by depositional processes and post-depositional diagenetic modification. Outcrop analogs were studied to better interpret the depositional processes that formed the reservoirs at the Ford Geraldine unit and to determine the dimensions of reservoir sandstone bodies. Facies relationships and bedding architecture within a single genetic unit exposed in outcrop in Culberson County, Texas, suggest that the sandstones were deposited in a system of channels and levees with attached lobes that initially prograded basinward, aggraded, and then turned around and stepped back toward the shelf. Channel sandstones are 10 to 60 ft thick and 300 to 3,000 ft wide. The flanking levees have a wedge-shaped geometry and are composed of interbedded sandstone and siltstone; thickness varies from 3 to 20 ft and length from several hundred to several thousands of feet. The lobe sandstones are broad lens-shaped bodies; thicknesses range up to 30 ft with aspect ratios (width/thickness) of 100 to 10,000. Lobe sandstones may be interstratified with laminated siltstones.

  8. Cajun Maritime expands gas production platform with help from Liebherr crane

    Energy Technology Data Exchange (ETDEWEB)



    The South Marsh Island (SMI) Block 217 platform is a productive offshore natural gas handling hub in the Gulf of Mexico's Flatrock multiple reservoir deep-gas discovery. This one platform alone could increase natural gas production in the United States by 13 per cent. Louisiana-based Cajun Maritime LLC is the specialized marine subsidiary of the civil and mechanical contracting group Cajun Industries. The company focuses on maintaining a safe working environment at all times. The company purchased a new Liebherr LR 1300 lattice boom crawler crane for the Flatrock project because of its quality, lifting capacity and price. This article described the features of the crane that make it particularly suitable for offshore drilling, such as sealed bearings, big engine, high line pull, and the unique ability to move the main boom and luffing jib simultaneously while under load. The LR 1300 was used for several major installations, including pipelines, a new service crane and a water treatment deck platform. The safety features of the LR 1300 include a reeving winch which is used to install the lifting cables; the small diameter reeving winch cable is much easier to handle than the old method of hand pulling; and riggers are not required to walk the boom of the crane. The cab computer is useful in low overhead clearance work and completely removes the human error factor. The electronic hydraulic controls eliminate the risk of accidental load loss often associated with old-style friction cranes. 3 figs.

    The U.S. Department of Energy (DOE) has instituted a basin-analysis study program to encourage drilling in underexplored and unexplored areas and increase discovery rates for hydrocarbons by independent oil companies within the continental United States. The work is being performed at the DOE's National Institute for Petroleum and Energy Research (NIPER) in Bartlesville, Oklahoma, by the Exploration and Drilling Group within BDM-Oklahoma (BDM), the manager of the facility for DOE. Several low-activity areas in the Mid-Continent, west, and southwest were considered for the initial study area (Reeves and Carroll 1994a). The Black Mesa region in northwestern Arizona is shown on the U.S. Geological Survey 1995 oil and gas map of the United States as an undrilled area, adapted from Takahashi and Gautier 1995. This basin was selected by DOE s the site for the initial NIPER-BDM survey to develop prospects within the Lower-48 states (Reeves and Carroll 1994b).

    Full Text Available The article discusses the development of the Gothic historical novel in English literature of the last third of the XVIII century. Initial installation on a stylized medieval romance, and attempts to reconstruct historical color associated with the overall objective aesthetic and artistic development of the Middle Ages (“The Castle of Otranto” Mr. Walpole, 1764 is replaced by the rejection of the historical and geographical exoticism and transferring activities in a much closer historical Age (K. Reeve “Old English Baron”, 1777. Image of real historical figures and famous historical events was a major literary discovery of the historic Gothic novel (S.Li “Refuge, or Tale of other times”, 1785, is preceded in this regard in the work by W. Scott. The next conquest of Gothic historical novel was the desire to enter the historical events in a common “historiosophical” story, reflecting the unbreakable laws of nature (C. Reeve, “Memoirs of Roger de Clarendon,” 1793. A similar trend is a characteristic of educational tradition, and yet, the historic Gothic novel, opens the way to a romantic historical novel, with its nostalgia for bygone times, tragic conflicts, an ideal hero, carried along by fate historic flow. Formation of the genre is analyzed in the context of socio-political and literary-aesthetic discussions era.

    Charbeneau, R.J.; Hertel, N.E.; Pollard, C.G.


    The Texas Low-Level Radioactive Waste Disposal Authority is completing two years of detailed on-site suitability studies of a potential low-level radioactive waste disposal site in Hudspeth County, Texas. The data from these studies have been used to estimate site specific parameters needed to do a performance assessment of the site. The radiological impacts of the site have been analyzed as required for a license application. The approach adopted for the performance assessment was to use simplified and yet conservative assumptions with regard to releases, radionuclide transport, and dose calculations. The methodologies employed in the performance assessment are reviewed in the paper. Rather than rely on a single computer code, a modular approach to the performance assessment was selected. The HELP code was used to calculate the infiltration rate through the trench covers and the amount of leachate released from this arid site. Individual pathway analyses used spreadsheet calculations. These calculations were compared with those from other computer models including CRRIS, INGDOS, PATHRAE, and MICROSHIELD copyright, and found to yield conservative estimates of the effective whole body dose. The greatest difficulty in performing the radiological assessment of the site was the selection of reasonable source terms for release into the environment. A surface water pathway is unreasonable for the site. Though also unlikely, the groundwater pathway with exposure through a site boundary well was found to yield the largest calculated dose. The more likely pathway including transport of leachate from the facility through the unsaturated zone and returning to the ground surface yields small doses. All calculated doses associated with normal releases of radioactivity are below the regulatory limits

    Full Text Available Severely injured patients with multiple and conflicting injuries present themselves to nursing professionals at critical care units faced with care management challenges. The goal of the present study is to evaluate nursing workload and verify the correlation between workload and the APACHE II severity index. It is a descriptive study, conducted in the Trauma Intensive Care Unit of a teaching hospital. We used the Nursing Activities Score and APACHE II as instruments. The sample comprised 32 patients, of which most were male, young adults, presenting polytrauma, coming from the Reference Emergency Unit, in surgical treatment, and discharged from the ICU. The average obtained on the Nursing Activities Score instrument was 72% during hospitalization periods. The data displayed moderate correlation between workload and patient severity. In other words, the higher the score, the higher the patient’s mortality risk. doi: 10.5216/ree.v16i2.22922.

    The Packaging Surveillance Program section of the Department of Energy (DOE) Manual 441.1-­1, Nuclear Material Packaging Manual (DOE 2008), requires DOE contractors to “ensure that a surveillance program is established and implemented to ensure the nuclear material storage package continues to meet its design criteria.”This 2017 update reflects changes to the surveillance plan resulting from surveillance findings as documented in Reeves et al. 2016. These findings include observations of corrosion in SAVY and Hagan containers and the indication (in one SAVY container) of possible filter membrane thermal degradation. This surveillance plan update documents the rationale for selecting surveillance containers, specifies the containers for 2017 surveillance, and identifies a minimum set of containers for 2018 surveillance. This update contains important changes to the previous surveillance plans.

  1. Morphology Of A Hot Prominence Cavity Observed with Hinode/XRT and SDO/AIA (United States)

    Weber, Mark A.; Reeves, K. K.; Gibson, S. E.; Kucera, T. A.


    Prominence cavities appear as circularly shaped voids in coronal emission over polarity inversion lines where a prominence channel is straddling the solar limb. The presence of chromospheric material suspended at coronal altitudes is a common but not necessary feature within these cavities. These voids are observed to change shape as a prominence feature rotates around the limb. We use a morphological model projected in cross-sections to fit the cavity emission in Hinode/XRT passbands, and then apply temperature diagnostics to XRT and SDO/AIA data to investigate the thermal structure. We find significant evidence that the prominence cavity is hotter than the corona immediately outside the cavity boundary. This investigation follows upon "Thermal Properties of A Solar Coronal Cavity Observed with the X-ray Telescope on Hinode" by Reeves et al., 2012, ApJ, in press.

    Ludwig Wittgenstein was born in 1889 in Vienna. As a scholar in Cambdrige University, his philosophical achievements are still major regarding the foundations of mathematics and language. In 1939, he took a job as a porter at London Guys' Hospital then under the Blitz. Wittgenstein met Drs. Grant and Reeve who worked in a dedicated "traumatic shock" under the auspices of the Medical Research Council unit, a unit which then moved to the Royal Victoria Infirmary in Newcastle; Wittgenstein followed them as a technician and improved the preparation of fine pieces of histology fixed by paraffin. He also invented a new device to record pulse pressure and paradoxical pulse search in laboratory rats. At the end of the war, he returned to Cambridge until 1949 and died in 1951.

  4. Conjugate gradient based projection - A new explicit methodology for frictional contact (United States)

    Tamma, Kumar K.; Li, Maocheng; Sha, Desong


    With special attention towards the applicability to parallel computation or vectorization, a new and effective explicit approach for linear complementary formulations involving a conjugate gradient based projection methodology is proposed in this study for contact problems with Coulomb friction. The overall objectives are focussed towards providing an explicit methodology of computation for the complete contact problem with friction. In this regard, the primary idea for solving the linear complementary formulations stems from an established search direction which is projected to a feasible region determined by the non-negative constraint condition; this direction is then applied to the Fletcher-Reeves conjugate gradient method resulting in a powerful explicit methodology which possesses high accuracy, excellent convergence characteristics, fast computational speed and is relatively simple to implement for contact problems involving Coulomb friction.

  7. Uniform Distribution of Yttrium and Heavy Rare Earth Elements in Round Top Mountain Rhyolite Deposit , Sierra Blanca Texas, USA: Data, Significance, and Origin (United States)

    Pingitore, N. E., Jr.; Clague, J. W.; Gorski, D.


    The Round Top Mountain peraluminous rhyolite, exposed at the surface in Sierra Blanca, Hudspeth County, west Texas, USA, is enriched in yttrium and heavy rare earth elements (YHREEs). Other potentially valuable elements in the deposit include Be, Li, U, Th, Sn, F, Nb, and Ta. Texas Rare Earth Resources Corp. proposes to extract the YHREEs from the host mineral variety yttrofluorite by inexpensive heap leaching with dilute sulfuric acid, which also releases some of the Be, Li, U, F, and Th from other soluble minor minerals. Data: Feldspars and quartz comprise 90-95% of the rhyolite, with pheonocrysts of up to 250 microns set in an aphanitic matrix that hosts the typically sub-micron target yttrofluorite. Reverse circulation cuttings from some 100 drill holes, two drill cores, and outcrop and trench observations suggest striking physical homogeneity through this billion-plus ton surface-exposed laccolith, about 1200 feet high and a mile in diameter (375 x 1600 m). Gray to pink, and other minor hues, color variation derives from magnetite—hematite redox reaction. Plots of Y, 13 REEs, U, Th, and Nb analyses from over 1500 samples collected from 64 drill holes (color codes in figure) exhibit remarkably little variation in the concentration of these elements with geographic position or depth within the laccolith. Importance: Uniform mineralization grades help insure against the mining production surprises often associated with vein deposits and heterogeneous open pit deposits. At Round Top, mine feedstock can be relatively constant over the life of the mine (multiple decades), so the mechanical mining process can be optimized early on and not need expensive alterations later. Likewise, the chemical and physical parameters of the heap leach can be perfected. The sensitive and expensive process of extraction of elements and element groups from the pregnant leach solution and purification also can be optimized. Origin: The remarkable homogeneity of the YHREE distribution

  8. On the Relationship Between High Speed Solar Wind Streams and Radiation Belt Electron Fluxes (United States)

    Zheng, Yihua


    Both past and recent research results indicate that solar wind speed has a close connection to radiation belt electron fluxes [e.g., Paulikas and Blake, 1979; Reeves et aI., 2011]: a higher solar wind speed is often associated with a higher level of radiation electron fluxes. But the relationship can be very complex [Reeves et aI., 2011]. The study presented here provides further corroboration of this viewpoint by emphasizing the importance of a global perspective and time history. We find that all the events during years 2010 and 2011 where the >0.8 MeV integral electron flux exceeds 10(exp 5) particles/sq cm/sr/s (pfu) at GEO orbit are associated with the high speed streams (HSS) following the onset of the Stream Interaction Region (SIR), with most of them belonging to the long-lasting Corotating Interaction Region (CIR). Our preliminary results indicate that during HSS events, a maximum speed of 700 km/s and above is a sufficient but not necessary condition for the > 0.8 MeV electron flux to reach 10(exp 5) pfu. But in the exception cases of HSS events where the electron flux level exceeds the 10(exp 5) pfu value but the maximum solar wind speed is less than 700 km/s, a prior impact can be noted either from a CME or a transient SIR within 3-4 days before the arrival of the HSS - stressing the importance of time history. Through superposed epoch analysis and studies providing comparisons with the CME events and the HSS events where the flux level fails to reach the 10(exp 5) pfu, we will present the quantitative assessment of behaviors and relationships of various quantities, such as the time it takes to reach the flux threshold value from the stream interface and its dependence on different physical parameters (e.g., duration of the HSS event, its maximum or average of the solar wind speed, IMF Bz, Kp). The ultimate goal is to apply what is derived to space weather forecasting.

    The N-S trending Davie Fracture Zone (DFZ) is often assumed to form the continent-ocean transform margin (COTM) of the Western Somali Basin. However, multiple plate tectonic reconstructions favour a pre-breakup location for Madagascar that crosses the DFZ, incompatible with its interpretation as the COTM (e.g., Lottes & Rowley, 1990; Reeves, 2014; Phethean et al., 2016). For the first time, we have identified classic COTM features in seismic reflection data from the Southern Rovuma Basin, to the west and inboard of the DFZ. These suggest a NNW trend to the margin, consistent with the tectonic reconstructions. 2D gravity models, with the seabed and top basement constrained by seismic data, are used to investigate the Moho structure across the Rovuma margin and are best fit using steep 'transform style' geometries, confirming the nature of the margin. We thus model generic COTM geometries elsewhere along the East African and Madagascan transform margins to locate best-fitting positions for these conjugate COTMs. This analysis confirms that the COTMs follow a NNW trend along the Rovuma Basin and Southern Madagascar, respectively, and allows a restoration of the conjugate COTMs. This restoration is used alongside geological maps and satellite imagery from Madagascar and East Africa to refine early plate motions and further constrain the precise origin of Madagascar within Gondwana. Our refined plate tectonic model independently predicts major observations made from seismic reflection and gravity data across the basin, including: regions of major transpression/transtension along the DFZ, merging of fracture zones to form the DFZ, oceanic crust on either side of the DFZ and within the Tanzania coastal basin, and the location of an abandoned MOR within the Tanzania coastal basin. We believe that this study finally provides conclusive evidence that Madagascar originated from within the Tanzania Coastal Basin, inboard of the DFZ, after some 30 years of debate regarding this

    Julia Estela Willrich Boell


    Full Text Available The goal of the present study is to identify the risk factors for developing diabetic foot. A cross-sectional study, with a convenience sample, developed with 70 individuals with diabetes mellitus (DM, registered in three basic health units in the municipality of Florianópolis/SC, Brazil, in the period from November 2010 to May 2011. Biometric data was collected regarding their sociodemographic, health and illness conditions. An assessment of the feet was also carried out. The average participant age was 66.17 years and time with diagnosed disease was under ten years (61.42%. The following risk factors were identified: advanced age; time of DM diagnosis; few years of schooling; overweight/obesity; inadequate diet; physical inactivity; inadequate metabolic control; lack of proper and specific foot care; and arterial hypertension. We conclude that the majority of the population presented one or more risk factors that favor the appearance of foot-related complications. doi: 10.5216/ree.v16i2.20460.

  12. A Conservation Ethic and the Collecting of Animals by Institutions of Natural Heritage in the Twenty-First Century: Case Study of the Australian Museum

    Directory of Open Access Journals (Sweden)

    Timothy Ikin


    Full Text Available Collecting of animals from their habitats for preservation by museums and related bodies is a core operation of such institutions. Conservation of biodiversity in the current era is a priority in the scientific agendas of museums of natural heritage in Australia and the world. Intuitively, to take animals from the wild, while engaged in scientific or other practices that are supposed to promote their ongoing survival, may appear be incompatible. The Australian Museum presents an interesting ground to consider zoological collecting by museums in the twenty-first century. Anderson and Reeves in 1994 argued that a milieu existed that undervalued native species, and that the role of natural history museums, up to as late as the mid-twentieth century, was only to make a record the faunal diversity of Australia, which would inevitably be extinct. Despite the latter, conservation of Australia’s faunal diversity is a key aspect of research programmes in Australia’s institutions of natural heritage in the current era. This paper analyses collecting of animals, a core task for institutions of natural heritage, and how this interacts with a professed “conservation ethic” in a twenty-first century Australian setting.

  14. Regulation of Mnemiopsis leidyi dynamics by potential changes in temperature and zooplankton conditions in the Black Sea. (United States)

    Salihoglu, B.; Fach, B.; Oguz, T.


    Providing a comprehensive understanding of the effects that cause formations of ctenophore blooms in the Black Sea is the main objective of this study. In order to analyse ctenophore dynamics in the Black Sea a zero-dimensional population based model of the ctenophore Mnemiopsis leidyi is developed. The stage resolving ctenophore model combines the modified form of stage resolving approach of Fennel, 2001 with the growth dynamics model of Kremer, 1976; Kremer and Reeve, 1989 under 4 stages of model-ctenophore. These stages include the different growth characteristics of egg, juvenile, transitional and adult stages. The dietary patterns of the different stages follows the observations obtained from the literature. The model is able to represent consistent development patterns, while reflecting the physiological complexity of a population of Mnemiopsis leidyi. Model results suggest that different nutritional requirement of each stage may serve as the bottlenecks for population growth and only when growth conditions are favorable for both larval and lobate stages, the high overall population growth rates may occur. Model is also used to analyse the influence of climatic changes on Mnemiopsis leidyi reproduction and outburst. This study presents and discussed how potential changes in temperature and zooplankton conditions in the Black Sea may regulate Mnemiopsis leidyi dynamics.

  15. Motivational Function of Plans and Goals

    Directory of Open Access Journals (Sweden)

    Sabina Alispahić


    Full Text Available The academic literature shows that by helping tune out distractions, goals can get individuals' to try harder, work longer, and achieve more. Goals that people set for themselves and that are devoted to attaining mastery are usually healthy. But goals imposed by others—sales targets, quarterly returns, standardized test scores—can sometimes have dangerous side effects (Pink, 2009. Because understanding action demands understanding intention, the idea of motivation is natural and readily expressed in everyday language. Cognitive mental events like goals and expectancies can function as a “spring to action”, a moving force that energizes and directs action in purposive ways (Reeve, 2005. Cognitive studies of motivation are dealing with relationship between cognition and action. Literature is indicating a few cognitive elements that can have motivational significance. The article presents the overview of theory and research about the motivational function of plans and goals, according to Goal setting theory (Locke & Latham, 1990 and Self-determination Theory (Deci & Ryan, 2000. Suggestions for additional research are also indicated.

  17. Material transport through porous media: a finite-element Galerkin model

    International Nuclear Information System (INIS)

    Duguid, J.O.; Reeves, M.


    A two-dimensional transient model for flow of a dissolved constituent through porous media has been developed. Mechanisms for advective transport, hydrodynamic dispersion, chemical absorption, and radioactive decay are included in the mathematical formulation. Implementations of quadrilateral finite elements, bilinear spatial interpolation, and Gaussian elimination are used in the numerical formulation. The programming language FORTRAN IV is used exclusively in the computer implementation. A listing of the program is included. This material-transport model is completely compatible with our moisture-transport model (Reeves and Duguid, 1975) for predicting advective Darcy velocities for porous media which may be partly unsaturated. In addition to a description of the mathematical formulation, the numerical treatment and the computer implementation results of two computer simulations are included in this document. One is a comparison with a well-known analytical treatment (Lapidus and Amundson, 1952) and is intended as a partial validation. The other simulation, a seepage-pond problem, is a more realistic demonstration of the capabilities of the computer model. Complete listings of input and output are given in the appendices so that this simulation may be used for check-out purposes. A comprehensive description of the material-transport computer model is given

  18. Landslide Occurrence Prediction Using Trainable Cascade Forward Network and Multilayer Perceptron

    Directory of Open Access Journals (Sweden)

    Mohammad Subhi Al-batah


    Full Text Available Landslides are one of the dangerous natural phenomena that hinder the development in Penang Island, Malaysia. Therefore, finding the reliable method to predict the occurrence of landslides is still the research of interest. In this paper, two models of artificial neural network, namely, Multilayer Perceptron (MLP and Cascade Forward Neural Network (CFNN, are introduced to predict the landslide hazard map of Penang Island. These two models were tested and compared using eleven machine learning algorithms, that is, Levenberg Marquardt, Broyden Fletcher Goldfarb, Resilient Back Propagation, Scaled Conjugate Gradient, Conjugate Gradient with Beale, Conjugate Gradient with Fletcher Reeves updates, Conjugate Gradient with Polakribiere updates, One Step Secant, Gradient Descent, Gradient Descent with Momentum and Adaptive Learning Rate, and Gradient Descent with Momentum algorithm. Often, the performance of the landslide prediction depends on the input factors beside the prediction method. In this research work, 14 input factors were used. The prediction accuracies of networks were verified using the Area under the Curve method for the Receiver Operating Characteristics. The results indicated that the best prediction accuracy of 82.89% was achieved using the CFNN network with the Levenberg Marquardt learning algorithm for the training data set and 81.62% for the testing data set.

  19. The adolescents’ school engagement: Assessment of its dimensions

    Directory of Open Access Journals (Sweden)

    José Manuel TOMÁS


    Full Text Available A topic that in the last years is getting relevance in school and students research is school engagement. This topic has been related, among other important constructs, with burnout of teachers and students, school performance, satisfaction with the school, behavioral disruption, goal orientation and motivational climate in the classroom, students-teachers relationships, and life satisfaction of the students. School engagement may be defined as the participation of the student in academic achievements, and it is understood as a multidimensional construct. The most repeated typology of dimensions recognizes three specific and overlapping dimensions: cognitive, behavioral, and emotional (affective. Frequently, education professionals have reported the lack of instruments to measure some students’ characteristics and psychosocial and behavioral variables in the classroom, as it is the case of school engagement. Recently, a fourth new dimension, personal agency, has been proposed (Reeve and Tseng, 2011. Veiga (2013 has been the first to present a self-report instrument, in Portuguese, to measure these four components, the Student Engagement Scale-4 dimensions (ses-4ds. Taken all this into account, the aim of this research was to study the reliability and validity of the aforementioned scale in two versions, Spanish and Portuguese, in large samples from the Dominican Republic and Angola. Results have shown a clear factor structure (after deleting two items, and adequate criterion-related and nomological validity. Accordingly, the ses-4d scale was considered a valid instrument to be applied in studies measuring school engagement of teenagers.

    Full Text Available This study describes and analyzes day-to-day issues in a Therapeutic Residential Care Center and the daily life characteristics of its residents. This case study was conducted in Caxias do Sul, based on an evaluation of the fourth generation together with a Methodology for Analyzing Everyday Life Networks. The following categories emerged: possibilities in the territory, participation and flexibility in household tasks, situations that mark living, employees who are mediators in conflict resolution, staff committed to the resident, freedom as a therapeutic tool, difficulties in daily life, and building of alliances. This study helped to get to know the structure of everyday life experienced by the residents, identifying some difficulties they face and the mechanisms used to overcome them, in addition to noticing that the professionals can be instrumental in strengthening a daily living that can be pluralized, busy, and enriched, while still respecting the uniqueness of each resident. doi: 10.5216/ree.v16i4.22923.

  1. Recent Chandra/HETGS and NuSTAR observations of the quasar PDS 456 and its Ultra-Fast Outflow (United States)

    Boissay Malaquin, Rozenn; Marshall, Herman L.; Nowak, Michael A.


    Evidence is growing that the interaction between outflows from active galactic nuclei (AGN) and their surrounding medium may play an important role in galaxy evolution, i.e. in the regulation of star formation in galaxies, through AGN feedback processes. Indeed, powerful outflows, such as the ultra-fast outflows (UFOs) that can reach mildly relativistic velocities of 0.2-0.4c, could blow away a galaxy’s reservoir of star-forming gas and hence quench the star formation in host galaxies. The low-redshift (z=0.184) radio-quiet quasar PDS 456 has showed the presence of a strong and blueshifted absorption trough in the Fe K band above 7 keV, that has been associated with the signature of such a fast and highly ionized accretion disk wind of a velocity of 0.25-0.3c. This persistent and variable feature has been detected in many observations of PDS 456, in particular by XMM-Newton, Suzaku and NuSTAR, together with other blueshifted absorption lines in the soft energy band (e.g. Nardini et al. 2015, Reeves et al. 2016). I will present here the results of the analysis of recent and contemporaneous high-resolution Chandra/HETGS and NuSTAR observations of PDS 456, and compare them with the previous findings.

  2. A Conceptual Framework for Graduate Teaching Assistant Professional Development Evaluation and Research. (United States)

    Reeves, Todd D; Marbach-Ad, Gili; Miller, Kristen R; Ridgway, Judith; Gardner, Grant E; Schussler, Elisabeth E; Wischusen, E William


    Biology graduate teaching assistants (GTAs) are significant contributors to the educational mission of universities, particularly in introductory courses, yet there is a lack of empirical data on how to best prepare them for their teaching roles. This essay proposes a conceptual framework for biology GTA teaching professional development (TPD) program evaluation and research with three overarching variable categories for consideration: outcome variables, contextual variables, and moderating variables. The framework's outcome variables go beyond GTA satisfaction and instead position GTA cognition, GTA teaching practice, and undergraduate learning outcomes as the foci of GTA TPD evaluation and research. For each GTA TPD outcome variable, key evaluation questions and example assessment instruments are introduced to demonstrate how the framework can be used to guide GTA TPD evaluation and research plans. A common conceptual framework is also essential to coordinating the collection and synthesis of empirical data on GTA TPD nationally. Thus, the proposed conceptual framework serves as both a guide for conducting GTA TPD evaluation at single institutions and as a means to coordinate research across institutions at a national level. © 2016 T.

    Full Text Available Simon P Kelly, Graham MB ReevesThe Royal Bolton Hospital, Bolton, UKPurpose: To consider the potential for ocular injury from writing implements by presenting four such cases, and to consider the incidence of such eye injuries from analysis of a national trauma database.Methods: The Home and Leisure Accident Surveillance System was searched for records of eye injuries from writing instruments to provide UK estimates of such injuries. Four patients with ocular penetrating injury from pens or pencils (especially when caused by children, and examined by the authors, are described which illustrate mechanisms of injury.Results: It is estimated that around 748 ocular pen injuries and 892 ocular pencil injuries of undetermined severity occurred annually in the UK during the database surveillance period 2000–2002. No eye injuries from swords, including toy swords and fencing foils, were reported.Conclusion: Ocular perforation sometimes occur from writing instruments that are thrown in the community, especially by children. Implications for policy and prevention are discussed. Non-specialists should have a low threshold for referring patients with eye injuries if suspicious of ocular penetration, even where caused by everyday objects, such as writing instruments.Keywords: eye injury, eye, children, mechanism, writing instruments, prevention

    Full Text Available Jesse Naghi, Ethan A Yalvac, Ali Pourdjabbar, Lawrence Ang, John Bahadorani, Ryan R Reeves, Ehtisham Mahmud, Mitul Patel Division of Cardiovascular Medicine, Sulpizio Cardiovascular Center, University of California, San Diego, CA, USA Abstract: Peripheral arterial disease (PAD involving the lower extremity is a major source of morbidity and mortality. Clinical manifestations of PAD span the spectrum from lifestyle limiting claudication to ulceration and gangrene leading to amputation. Advancements including balloon angioplasty, self-expanding stents, drug-eluting stents, and atherectomy have resulted in high technical success rates for endovascular therapy in patients with PAD. However, these advances have been limited by somewhat high rates of clinical restenosis and clinically driven target lesion revascularization. The recent introduction of drug-coated balloon technology shows promise in limiting neointimal hyperplasia induced by vascular injury after endovascular therapies. This review summarizes the contemporary clinical data in the emerging area of drug-coated balloons. Keywords: drug-coated balloons, endovascular, percutaneous transluminal angioplasty, paclitaxel, peripheral arterial disease

  5. Technical and economic assessment of solar hybrid repowering. Final report

    Energy Technology Data Exchange (ETDEWEB)



    Public Service Company of New Mexico (PNM) has performed a Technical and Economic Assessment of Solar Hybrid Repowering under funding by the Department of Energy (DOE), the Electric Power Research Institute (EPRI), Western Energy Supply and Transmission (WEST) Associates, and a number of southwestern utilities. Solar hybrid repowering involves placement of solar hardware adjacent to and connected to existing gas- and oil-fueled electric generation units to displace some of or all the fossil fuel normally used during daylight hours. The subject study assesses the technical economic viability of the solar hybrid repowering concept within the southwestern United States and the PNM system. This document is a final report on the study and its results. The study was divided into the six primary tasks to allow a systematic investigation of the concept: (1) market survey and cost/benefit analysis, (2) study unit selection, (3) conceptual design and cost estimates, (4) unit economic analysis, (5) program planning, future phases, and (6) program management. Reeves Station No. 2 at Albuquerque, New Mexico, was selected for repowering with a design goal of 50 percent (25 MWe). The solar system design is based on the 10 MW solar central receiver pilot plant preliminary design for Barstow, California. SAN--1608-4-2 contains the technical drawings. (WHK)

  6. The energy balance in coronal holes and average quiet-sun regions (United States)

    Raymond, J. C.; Doyle, J. G.


    Emission measure curves are presented for average coronal hole and quiet-sun spectra taken during the Skylab mission by Vernazza and Reeves (1978), and the curves are used to discuss the energy balance in each region. Close-coupling calculations are used for the Be sequence, assuming a 10 level ion; for B sequence ions mainly distorted wave calculations in an 11 level ion are used, but close-coupling cross sections are used for some ions; for C and Mg sequence ions, distorted wave calculations are used with 15 and 10 level ions, respectively, and close-coupling results are used for Li-like ions with two levels. Results are presented and include the following: the coronal hole spectrum shows a smaller slope in the emission measure distribution, consistent with the expected outflow effects. It is concluded that the simple constant pressure models of static coronal loops of constant cross section are basically able to match the observed emission measure distribution of the average quiet sun between 1,000,000 and 10,000,000 K. However, the cell center and network distributions are respectively steeper and shallower than predicted by the detailed cooling curve.

  7. More terminological clarity in the interprofessional field – a call for reflection on the use of terminologies, in both practice and research, on a national and international level

    Directory of Open Access Journals (Sweden)

    Mitzkat, Anika


    Full Text Available The terminology which has been used up until now within interprofessional healthcare has been characterised by a certain definitional weakness, which, among other factors, has been caused by an uncritical adoption of language conventions and a lack of theoretical reflection. However, as terminological clarity plays a significant role in the development and profiling of a discipline, the clarification and definition of commonly-used terminology has manifested itself as a considerable objective for the interprofessional research community. One of the most important journals for research in the area of interprofessional education and care, the Journal of Interprofessional Care, has expanded its author guidelines relating to terminology, modeled after the conceptual considerations of the research group around Barr et. al and Reeves et al. A German translation of the suggested terms therein has been presented in this contribution, and discussed in light of the challenges to a possible adaptation for the German-speaking world. The objective is to assist communication in practice and research in becoming clearer, while promoting an increasing awareness to and the transparency of determined definitions and terminologies.

  8. Mujeres que engendran hijos expuestos al virus de inmunodeficiencia humana: representaciones sociales de la maternidad

    Directory of Open Access Journals (Sweden)

    Marli Teresinha Gimeniz Galvão


    Full Text Available Descriptive and qualitative study aimed to identify the social representations of motherhood in women bearing children exposed to the human immunodeficiency virus (HIV. Performed between February and March 2011 in a hospital considered a benchmark in caring for people with HIV, with ten biological mothers with at least one child born exposed to the virus. Semi-structured interviews were used for data collection. Analysis of the testimonials determined the categories: guilt and fear of giving birth to a child with HIV, discrimination and concealment of having HIV, child overprotection, lack of family support, and religiosity as a way of coping. The social representations of the women was an organization of meanings that acted as a system for interpreting reality, governing the relations with the physical and social environment, thus determining behaviors and practices. Furthermore, there is a need for skilled health care and a social network of support for promoting health. doi: 10.5216/ree.v16i4.22760.

  9. Reduced fatalism and increased prevention behavior after two high-profile lung cancer events. (United States)

    Portnoy, David B; Leach, Corinne R; Kaufman, Annette R; Moser, Richard P; Alfano, Catherine M


    The positive impact of media coverage of high-profile cancer events on cancer prevention behaviors is well-established. However, less work has focused on potential adverse psychological reactions to such events, such as fatalism. Conducting 3 studies, the authors explored how the lung cancer death of Peter Jennings and diagnosis of Dana Reeve in 2005 related to fatalism. Analysis of a national media sample in Study 1 found that media coverage of these events often focused on reiterating the typical profile of those diagnosed with lung cancer; 38% of the media mentioned at least 1 known risk factor for lung cancer, most often smoking. Data from a nationally representative survey in Study 2 found that respondents reported lower lung cancer fatalism, after, compared with before, the events (OR = 0.16, 95% CI [0.03, 0.93]). A sustained increase in call volume to the national tobacco Quitline after these events was found in Study 3. These results suggest that there is a temporal association between high-profile cancer events, the subsequent media coverage, psychological outcomes, and cancer prevention behaviors. These results suggest that high-profile cancer events could be leveraged as an opportunity for large-scale public heath communication campaigns through the dissemination of cancer prevention messages and services.

  10. Balance and ambulation improvements in individuals with chronic incomplete spinal cord injury using locomotor training-based rehabilitation. (United States)

    Harkema, Susan J; Schmidt-Read, Mary; Lorenz, Douglas J; Edgerton, V Reggie; Behrman, Andrea L


    To evaluate the effects of intensive locomotor training on balance and ambulatory function at enrollment and discharge during outpatient rehabilitation after incomplete SCI. Prospective observational cohort. Seven outpatient rehabilitation centers from the Christopher and Dana Reeve Foundation NeuroRecovery Network (NRN). Patients (N=196) with American Spinal Injury Association Impairment Scale (AIS) grade C or D SCI who received at least 20 locomotor training treatment sessions in the NRN. Intensive locomotor training, including step training using body-weight support and manual facilitation on a treadmill followed by overground assessment and community integration. Berg Balance Scale; Six-Minute Walk Test; 10-Meter Walk Test. Outcome measures at enrollment showed high variability between patients with AIS grades C and D. Significant improvement from enrollment to final evaluation was observed in balance and walking measures for patients with AIS grades C and D. The magnitude of improvement significantly differed between AIS groups for all measures. Time since SCI was not associated significantly with outcome measures at enrollment, but was related inversely to levels of improvement. Significant variability in baseline values of functional outcome measures is evident after SCI in individuals with AIS grades C and D and significant functional recovery can continue to occur even years after injury when provided with locomotor training. These results indicate that rehabilitation, which provides intensive activity-based therapy, can result in functional improvements in individuals with chronic incomplete SCI.

  11. NeuroRecovery Network provides standardization of locomotor training for persons with incomplete spinal cord injury. (United States)

    Morrison, Sarah A; Forrest, Gail F; VanHiel, Leslie R; Davé, Michele; D'Urso, Denise


    To illustrate the continuity of care afforded by a standardized locomotor training program across a multisite network setting within the Christopher and Dana Reeve Foundation NeuroRecovery Network (NRN). Single patient case study. Two geographically different hospital-based outpatient facilities. This case highlights a 25-year-old man diagnosed with C4 motor incomplete spinal cord injury with American Spinal Injury Association Impairment Scale grade D. Standardized locomotor training program 5 sessions per week for 1.5 hours per session, for a total of 100 treatment sessions, with 40 sessions at 1 center and 60 at another. Ten-meter walk test and 6-minute walk test were assessed at admission and discharge across both facilities. For each of the 100 treatment sessions percent body weight support, average, and maximum treadmill speed were evaluated. Locomotor endurance, as measured by the 6-minute walk test, and overground gait speed showed consistent improvement from admission to discharge. Throughout training, the patient decreased the need for body weight support and was able to tolerate faster treadmill speeds. Data indicate that the patient continued to improve on both treatment parameters and walking function. Standardization across the NRN centers provided a mechanism for delivering consistent and reproducible locomotor training programs across 2 facilities without disrupting training or recovery progression.

    Full Text Available The analysis presented here introduces three optimization techniques namely, Hooke and Jeeves, Fletcher-Reeves and Davidon-Fletcher-Powell as applied to design of the circular footing adjacent to slopes. A computer program was developed to solve this design problem using the conventional structural design approach   in conjunction with these methods, A simple study was performed to detect the sensitivity of the objective function to its design variables. A further parametric study was performed regarding the geometric configurations of the footing and loading conditions in order to provide the geotechnical engineer with some useful design curves. Hooke and Jeeves method has been proved to be very instructive in exposing the effect of the other methods.It has been proved that the minimum cost of the circular footing increases with the increase of the load whereas it decreases as the angle of internal friction increases and the Dcl/B ratio (column diameter/diameter of footing.

  13. Conductivity hysteresis in polymer electrolytes incorporating poly(tetrahydrofuran)

[Department of Materials Science and Engineering, Massachusetts Institute of Technology, Cambridge, MA (United States); Kumar, Sundeep; Shao-Horn, Yang [Department of Mechanical Engineering, Massachusetts Institute of Technology, Cambridge, MA (United States)


    Conductivity hysteresis and room temperature ionic conductivities >10{sup -3}S/cm were recently reported for electrolytes prepared from blends of an amphiphilic comb copolymer, poly[2,5,8,11,14-pentaoxapentadecamethylene (5-hexadecyloxy-1,3-phenylene)] (polymer I), and a linear multiblock copolymer, poly(oligotetrahydrofuran-co-dodecamethylene) (polymer II), following thermal treatment [F. Chia, Y. Zheng, J. Liu, N. Reeves, G. Ungar, P.V. Wright, Electrochim. Acta 43 (2003) 1939]. To investigate the origin of these effects, polymers I and II were synthesized in this work, and the conductivity and thermal properties of the individual polymers were investigated. AC impedance measurements were conducted on I and II doped with LiBF{sub 4} or LiClO{sub 4} during gradual heating to 110{sup o}C and slow cooling to room temperature. Significant conductivity hysteresis was seen for polymer II, and was similarly observed for poly(tetrahydrofuran) (PTHF) homopolymer at equivalent doping levels. From thermogravimetric analysis (TGA), gel permeation chromatography (GPC) and {sup 1}H NMR spectroscopy, both polymer II and PTHF were found to partially decompose to THF during heat treatment, resulting in a self-plasticizing effect on conductivity.

  14. Interprofessional care in intensive care settings and the factors that impact it: results from a scoping review of ethnographic studies. (United States)

    Paradis, Elise; Leslie, Myles; Gropper, Michael A; Aboumatar, Hanan J; Kitto, Simon; Reeves, Scott


    At the heart of safe cultures are effective interactions within and between interprofessional teams. Critical care clinicians see severely ill patients who require coordinated interprofessional care. In this scoping review, we asked: "What do we know about processes, relationships, organizational and contextual factors that shape the ability of clinicians to deliver interprofessional care in adult ICUs?" Using the 5-stage process established by Levac et al. (2010), we reviewed 981 abstracts to identify ethnographic articles that shed light on interprofessional care in the intensive care unit. The quality of selected articles is assessed using best practices in ethnographic research; their main insights evaluated in light of an interprofessional framework developed by Reeves et al (Interprofessional Teamwork for Health and Social Care. San Francisco, CA: Wiley-Blackwell; 2010). Overall, studies were of mixed quality, with an average (SD) score of 5.8 out of 10 (1.77). Insights into intensive care unit cultures include the importance of paying attention to workflow, the nefarious impact of hierarchical relationships, the mixed responses to protocols imposed from the top down, and a general undertheorization of sex and race. This review highlights several lessons for safe cultures and argues that more needs to be known about the context of critical care if quality and safety interventions are to succeed.

  15. The billing process at a teaching hospital specialized in cardiology and pulmonology

    Directory of Open Access Journals (Sweden)

    Gabriela Favaro Faria Guerrer


    Full Text Available The objective of this exploratory study was to describe and map out the billing process in a public tertiary-level university hospital specialized in cardiology and pulmonology. In the period between May and June of 2012, we identified and documented the steps in the process validated by the professionals involved in the hospital bill audit service. We found that during billing pre-analysis, auditors make corrections to justify the billing of procedures and to avoid unwarranted billing and loss of revenue. Mapping out the process allowed us to propose strategies to minimize the time for presenting bills to payment sources. By bringing visibility to this process, which is fundamental for the economic-financial balance of the studied hospital, we bring such knowledge to the public domain. Thus, it is accessible to other health organizations that wish to increment their revenue and reduce divergences between patient charts and the patient’s hospital bill. doi: 10.5216/ree.v16i3.23487.

  16. A comparative study of breast cancer diagnosis based on neural network ensemble via improved training algorithms. (United States)

    Azami, Hamed; Escudero, Javier


    Breast cancer is one of the most common types of cancer in women all over the world. Early diagnosis of this kind of cancer can significantly increase the chances of long-term survival. Since diagnosis of breast cancer is a complex problem, neural network (NN) approaches have been used as a promising solution. Considering the low speed of the back-propagation (BP) algorithm to train a feed-forward NN, we consider a number of improved NN trainings for the Wisconsin breast cancer dataset: BP with momentum, BP with adaptive learning rate, BP with adaptive learning rate and momentum, Polak-Ribikre conjugate gradient algorithm (CGA), Fletcher-Reeves CGA, Powell-Beale CGA, scaled CGA, resilient BP (RBP), one-step secant and quasi-Newton methods. An NN ensemble, which is a learning paradigm to combine a number of NN outputs, is used to improve the accuracy of the classification task. Results demonstrate that NN ensemble-based classification methods have better performance than NN-based algorithms. The highest overall average accuracy is 97.68% obtained by NN ensemble trained by RBP for 50%-50% training-test evaluation method.

    Full Text Available A cross-sectional study with a descriptive analysis of 81 patients submitted to radical prostatectomy (RP. Our objective was to correlate quality of life (QL according to the EORTC-QLQ C30 with age group and time after surgery. Mean age was 65.7 years. Most sought the care of urology, asymptomatic. Some referred former smoking (49.9% and high blood pressure (53.1%. Mean preoperative SBP was 8.4 ng/ml. Most participants were in stages T2c to T3, Gleason ?6 and over a year after surgery. Erectile dysfunction presented in 90.1%, and urinary incontinence in 33.3%. Functional and overall health scales presented high QL indexes, and symptomatology, with low ones. Older adults presented higher QL regarding emotional functioning, financial difficulties and overall health, as well as those with over a year after surgery, regarding cognitive functioning and fatigue. Although QL was not greatly affected, there were differences between age groups and time after surgery. doi: 10.5216/ree.v16i3.21589.

  18. Thermal Structure of Supra-Arcade Plasma in Two Solar Flares (United States)

    Reeves, Katharine K.; Savage, Sabrina; McKenzie, David E.; Weber, Mark A.


    In this work, we use Hinode/XRT and SDO/AIA data to determine the thermal structure of supra-arcade plasma in two solar flares. The first flare is a Ml.2 flare that occurred on November 5, 2010 on the east limb. This flare was one of a series of flares from AR 11121, published in Reeves & Golub (2011). The second flare is an XI.7 flare that occurred on January 27, 2012 on the west limb. This flare exhibits visible supra-arcade downflows (SADs), where the November 2010 flare does not. For these two flares we combine XRT and AlA data to calculate DEMs of each pixel in the supra-arcade plasma, giving insight into the temperature and density structures in the fan of plasma above the post-flare arcade. We find in each case that the supra-arcade plasma is around 10 MK, and there is a marked decrease in the emission measure in the SADs. We also compare the DEMs calculated with the combined AIA/XRT dataset to those calculated using AIA alone.

  19. Three New Records of Gastropoda (Mollusca) from the Nansha Islands, China (United States)

    Chen, Zhiyun; Shi, Wei; Gong, Li


    The Nansha Islands, China, have extremely high marine biodiversity and hundreds of mollusks have been reported there. Benthos resources investigations of the intertidal and subtidal zone around the Nansha Islands have been continuously performed for decades, and recently, dozens of new species and new records of mollusks have been reported from this area. This paper dealt with three new record species of the Gastropoda from Chinese waters: Cerithium salebrosum Sowerby II, 1855, Vexillum militare (Reeve, 1845) and Vexillum bizonale (Dautzenberg et Bouge, 1923), respectively belonging to three families: Cerithiidae Fleming, 1822, and Costellariidae MacDonald, 1860. All specimens were collected from the Nansha Islands during the benthos resources investigations on the intertidal zone of islands and reefs in the South China Sea in recent years. Diagnosis and geographic descriptions of both genus and species, illustrations of each species were given in this contribution, and discussion of taxonomy, identification features and faunal characteristics were presented. All examined specimens were deposited in the Marine Biodiversity Collections of South China Sea, Chinese Academy of Sciences.

  20. The last straw!: a tool for participatory education about the social determinants of health. (United States)

    Rossiter, Kate; Reeve, Kate


    In response to a scarcity of teaching tools regarding the social determinants of health (SDOH), Kate Reeve and Kate Rossiter created The Last Straw! board game, an innovative participatory education tool to facilitate and engage critical thinking about the SDOH. The Last Straw! is designed to encourage discussion about the SDOH, promote critical thinking, and build empathy with marginalized people. The game begins as each player rolls the dice to create a character profile, including socioeconomic status (SES), race, and gender. Based on this profile, players then receive a certain number of "vitality chips." Moving across the board, players encounter scenarios that cause them to gain and lose chips based on their profile. The player who finishes the game with the most chips wins the game. The game can be facilitated for a variety of audiences, including both players with no prior knowledge of the SDOH and those experienced in the field. The game has been played with students, policymakers, and community workers, among others, and has been met with immense enthusiasm. Here, we detail the game's reception within the community, including benefits, limitations, and next steps.

  1. Selecting an interprofessional education model for a tertiary health care setting. (United States)

    Menard, Prudy; Varpio, Lara


    The World Health Organization describes interprofessional education (IPE) and collaboration as necessary components of all health professionals' education - in curriculum and in practice. However, no standard framework exists to guide healthcare settings in developing or selecting an IPE model that meets the learning needs of licensed practitioners in practice and that suits the unique needs of their setting. Initially, a broad review of the grey literature (organizational websites, government documents and published books) and healthcare databases was undertaken for existing IPE models. Subsequently, database searches of published papers using Scopus, Scholars Portal and Medline was undertaken. Through this search process five IPE models were identified in the literature. This paper attempts to: briefly outline the five different models of IPE that are presently offered in the literature; and illustrate how a healthcare setting can select the IPE model within their context using Reeves' seven key trends in developing IPE. In presenting these results, the paper contributes to the interprofessional literature by offering an overview of possible IPE models that can be used to inform the implementation or modification of interprofessional practices in a tertiary healthcare setting.

    With the completion of genome sequencing projects, there are a large number of proteins for which we have little or no functional information. Since protein function is closely related to three-dimensional conformation, structural proteomics is one avenue where the role of proteins with unknown function can be investigated. In the present structural project, the structure of MTH187 has been determined by solution-state NMR spectroscopy. This protein of 12.4 kDa is one of the 424 non-membrane proteins that were cloned and purified for the structural proteomic project of Methanobacterium thermoautotrophicum [Christendat, D., Yee, A., Dharamsi, A., Kluger, Y., Gerstein, M., Arrowsmith, C.H. and Edwards, A.M. (2000) Prog. Biophys. Mol. Biol., 73, 339-345]. Methanobacterium thermoautotrophicum is a thermophilic archaeon that grows optimally at 65 deg. C. A particular characteristic of this microorganism is its ability to generate methane from carbon dioxide and hydrogen [Smith, D.R., Doucette-Stamm, L.A., Deloughery, C., Lee, H., Dubois, J., Aldredge, T., Bashirzadeh, R., Blakely, D., Cook, R., Gilbert, K., Harrison, D., Hoang, L., Keagle, P., Lumm, W., Pothier, B., Qiu, D., Spadafora, R., Vicaire, R., Wang, Y., Wierzbowski, J., Gibson, R., Jiwani, N., Caruso, A., Bush, D., Reeve, J.

  3. Algorithms for the optimization of RBE-weighted dose in particle therapy. (United States)

    Horcicka, M; Meyer, C; Buschbacher, A; Durante, M; Krämer, M


    We report on various algorithms used for the nonlinear optimization of RBE-weighted dose in particle therapy. Concerning the dose calculation carbon ions are considered and biological effects are calculated by the Local Effect Model. Taking biological effects fully into account requires iterative methods to solve the optimization problem. We implemented several additional algorithms into GSI's treatment planning system TRiP98, like the BFGS-algorithm and the method of conjugated gradients, in order to investigate their computational performance. We modified textbook iteration procedures to improve the convergence speed. The performance of the algorithms is presented by convergence in terms of iterations and computation time. We found that the Fletcher-Reeves variant of the method of conjugated gradients is the algorithm with the best computational performance. With this algorithm we could speed up computation times by a factor of 4 compared to the method of steepest descent, which was used before. With our new methods it is possible to optimize complex treatment plans in a few minutes leading to good dose distributions. At the end we discuss future goals concerning dose optimization issues in particle therapy which might benefit from fast optimization solvers.

    Parental reflective functioning (PRF) is the capacity to focus on experience and feelings in oneself and in the child. Individual differences in PRF reportedly affect child attachment and socioemotional development. In this study, we report work on developing a questionnaire to assess PRF during pregnancy (Prenatal Parental Reflective Functioning Questionnaire; P-PRFQ). The factor structure of the 33-item version of the P-PRFQ was explored using pilot study data from the Finn Brain Birth Cohort Study (n = 124 mothers, n = 82 fathers). Construct validity was assessed against the Pregnancy Interview (PI; A. Slade, L. Grunebaum, L. Huganir, & M. Reeves, 1987, 2002, 2011) in a subsample of 29 mothers from the same pilot sample. Exploratory and confirmatory factor analysis resulted in a 14-item P-PRFQ, with three factors which seem to capture relevant aspects of prenatal parental mentalization-F1: "Opacity of mental states," F2: "Reflecting on the fetus-child," and F3: "The dynamic nature of the mental states." Functioning of the factor structure was further tested in the large cohort with 600 mothers and 600 fathers. Correlations with the PI result were high, both regarding total and factor scores of the P-PRFQ. Cost-effective tools to assess key areas of early parenting are needed for both research and clinical purposes. The 14-item P-PRFQ seems to be an applicable and promising new tool for assessing very early parental mentalizing capacity. © 2015 Michigan Association for Infant Mental Health.

  5. Mercury in a thin layer in HgMn stars: A test of a diffusion model

    International Nuclear Information System (INIS)

    Megessier, C.; Michaud, G.; Weiler, E.J.


    Lines of the first three states of ionization of mercury have been observed in μ Leporis and chi Lupi using the Copernicus satellite. Lines of Hg II and Hg III have been observed in α Andromedae. There appears to be an absorption feature at every wavelength where there is expected to be a mercury line. The presence of all three states of ionization is likely in μ Lep and chi Lup. The relative equivalent widths of the lines of the various states of ionization do not depend on the effective temperature of the stars, in contradiction to what is expected if mercury were uniformly distributed in the atmosphere. It is, however, expected if mercury has been concentrated, by diffusion, in a thin layer, where the radiative forces just equal the gravitational forces on mercury. That mercury should be so concentrated is also required by the explanation of the mercury isotope anomaly proposed by Michaud, Reeves, and Charland. The diffusion model for Ap stars predicts in its simplest form the presence of very thin layers. However, any leftover turbulence may increase the depth of these layers without eliminating the element separation

  6. Interprofessional leadership training in MCH social work. (United States)

    Pecukonis, Edward; Doyle, Otima; Acquavita, Shauna; Aparicio, Elizabeth; Gibbons, Maya; Vanidestine, Todd


    The need to train health social workers to practice interprofessionally is an essential goal of social work education. Although most health social workers have exposure to multidisciplinary practice within their field work, few social work education programs incorporate interprofessional learning as an integrated component of both course work and field experiences (McPherson, Headrick, & Moss, 2001; Reeves, Lewin, Espin, & Zwaranstein, 2010; Weinstein, Whittington, & Leiba, 2003). In addition, little is written about the kinds of curricula that would effectively promote interdisciplinary training for social work students. These findings are particularly puzzling since there is increasing and compelling evidence that interdisciplinary training improves health outcomes (IOM, 2001). This article describes a social work education program that incorporates an Interprofessional education and leadership curriculum for Maternal and Child Health Social Work (MCHSW) at the University of Maryland's School of Social Work. The University of Maryland's Interprofesisonal Training Model is described along with the components needed to formulate an interdisciplinary learning experience. Various outcomes and lessons learned are discussed.

  7. Cost of installing and turning off hemodialysis on patients with central venous catheters

    Directory of Open Access Journals (Sweden)

    Gillene Santos Ferreira


    Full Text Available The objective was to identify the average total cost (ATC for installing and turning off hemodialysis on patients with central venous catheters. This quantitative, exploratory, and descriptive research, in the mode of a single-case study, was conducted in a public university hospital. The non-probabilistic sample corresponded to the observation of 100 installations and 100 terminations of hemodialysis on 42 patients during 23 days of collection. The ATC was calculated by multiplying the time spent by nurses by the unit cost of direct labor, and adding the cost of materials, solutions, and medications. The Brazilian currency (R$ was used for the calculations. The ATC for installation was R$ 80.10 and for shutting off was R$ 13.04, totaling R$ 93.14 per hemodialysis session. The results obtained will facilitate a better planning of the allocation of human, material, and financial resources enabling the increase of managerial strategies aimed at economic efficiency. doi: 10.5216/ree.v16i4.23044.

  9. Vulnerability of families with children with intestinal stomas

    Clara Ferraz Lazarini Zacarin


    Full Text Available Intestinal stomas cause transformations in the body and create specific and continuous needs for care that imply in hospitalization and surgeries. In this context, we applied the concept of family vulnerability in order to identify the vulnerability of the family living with a child who has intestinal stoma. It is a qualitative study which interviewed the mothers of children with this chronic condition. We used narrative analysis based on the concept of family vulnerability. The results display that the family has gone through previous noteworthy experiences associated with the child’s condition. The family cares for the child on their own and seeks ways to control the situation and regain autonomy, hoping for stoma reversal. Based on the concept of vulnerability, we observed that these families can be considered vulnerable, for they experience threats to their autonomy, but are moved by the hope of reversal and intestinal tract reconstruction. doi: 10.5216/ree.v16i2.26639.

  10. Knowledge and attitudes of health professionals regarding pain assessment and management in neonates

    Verusca Kelly Capellini


    Full Text Available Multiple factors can have an effect on pain management in neonates, which motivated us to analyze the knowledge and attitudes held by doctors, nurses and nursing assistants who work in neonatal units in a hospital in the state of São Paulo, Brazil, regarding neonatal pain assessment and management. This study is descriptive and was conducted with 57 health professionals. The results of the questionnaires revealed that only one professional believed that neonates do not feel pain, and 53 professionals stated the contrary, but were not familiar with neonate pain assessment scales. Professionals indicated fentanyl and midazolam as adequate analgesics for acute pain. Umbilical catheterization, gastric probing and heel pad puncture were considered painful procedures and indications for the use of analgesia.  Health professionals are knowledgeable about pain in neonates, but this knowledge is not reflected in clinical practice. It is essential for professionals to be trained regarding knowledge transfer so that neonate pain assessment and management can be implemented. doi: 10.5216/ree.v16i2.23611.

    Full Text Available Eileen Reeves (Department of Comparative Literature, Princeton University, Princeton, New Jersey, 08544 and Mary Posani (Department of French and Italian, The Ohio State University, Columbus, Ohio, 43221 provide a translation of Father Pietro Angelo Secchi’s classic work “ Secchi A. Sulla Teoria Delle Macchie Solari: Proposta dal sig. Kirchoff” as it appeared in Bullettino Meteorologico dell’ Osservatorio del Collegio Romano , 31 January 1864, v.3(4, 1–4. This was the first treatise to propose a partic- ulate photosphere floating on the gaseous body of the Sun. The idea would dominate astrophysical thought for the next 50 years. Secchi appears to have drafted the article, as a response to Gustav Kirchhoff’s proposal, echoing early Galilean ideas, that sunspots represented clouds which floated above the photosphere. Other than presenting a new solar model, noteworthy aspects of this work include Secchi’s appropriate insistence that materials do not emit the same light at the same temperature and his gentle rebuke of Kirchhoff relative to commenting on questions of astronomy.

  13. Celebrating Professor Britton Chance (1913-2010), a founding father of redox sciences. (United States)

    Ohnishi, Tomoko; Zweier, Jay L


    Renowned great scientist and redox pioneer, Dr. Britton Chance, closed his 97 years of legendary life on November 16, 2010. He was the Eldridge Reeves Johnson emeritus professor of biophysics, physical chemistry, and radiologic physics at the University of Pennsylvania. He achieved fame as a prominent biophysicist and developer of highly innovative biomedical instrumentation. His scientific career stretched over almost one century and he achieved many scientific and engineering breakthroughs throughout his long prolific career. The advances that he and his colleagues achieved led to great strides in our understanding of biology and disease. He was among the first scientists to recognize the importance of free radicals and reactive oxygen species in mitochondrial metabolism and cells as well as to map pathways of redox biology and signaling. Dr. Chance served as a pioneer and inspiration to generations of researchers in the fields of redox biochemistry, metabolism, and disease. He will be missed by all of us in the research community but will live on through his monumental scientific accomplishments, the novel instrumentation he developed, as well as the many scientists whom he trained and influenced.

  14. Laser scanning measurements on trees for logging harvesting operations. (United States)

    Zheng, Yili; Liu, Jinhao; Wang, Dian; Yang, Ruixi


    Logging harvesters represent a set of high-performance modern forestry machinery, which can finish a series of continuous operations such as felling, delimbing, peeling, bucking and so forth with human intervention. It is found by experiment that during the process of the alignment of the harvesting head to capture the trunk, the operator needs a lot of observation, judgment and repeated operations, which lead to the time and fuel losses. In order to improve the operation efficiency and reduce the operating costs, the point clouds for standing trees are collected with a low-cost 2D laser scanner. A cluster extracting algorithm and filtering algorithm are used to classify each trunk from the point cloud. On the assumption that every cross section of the target trunk is approximate a standard circle and combining the information of an Attitude and Heading Reference System, the radii and center locations of the trunks in the scanning range are calculated by the Fletcher-Reeves conjugate gradient algorithm. The method is validated through experiments in an aspen forest, and the optimized calculation time consumption is compared with the previous work of other researchers. Moreover, the implementation of the calculation result for automotive capturing trunks by the harvesting head during the logging operation is discussed in particular.

  15. Karyotype description of Pomacea patula catemacensis (Caenogastropoda, Ampullariidae), with an assessment of the taxonomic status of Pomacea patula. (United States)

    Diupotex-Chong, María Esther; Cazzaniga, Néstor J; Hernández-Santoyo, Alejandra; Betancourt-Rule, José Miguel


    Mitotic chromosomes of the freshwater snail Pomacea patula catemacensis (Baker 1922) were analyzed on gill tissue of specimens from the type locality (Lake Catemaco, Mexico). The diploid number of chromosomes is 2n = 26, including nine metacentric and four submetacentric pairs; therefore, the fundamental number is FN = 52, No sex chromosomes could be identified. The same chromosome number and morphology were already reported for P. flagellata, i.e., the other species of the genus living in Mexico. The basic haploid number for family Ampullariidae was reported to be n = 14 in the literature; so, its reduction to n = 13 is probably an apomorphy of the Mexican Pomacea snails. Lanistes bolteni, from Egypt, also shows n = 13, but its karyotype is much more asymmetrical, and seems to have evolved independently from P. flagellata and P. patula catemacensis. The nominotypical subspecies, P. patula patula (Reeve 1856), is a poorly known taxon, whose original locality is unknown. A taxonomical account is presented here, and a Mexican origin postulated as the most parsimonious hypothesis.

  16. Numerical methods for finding periodic points in discrete maps. High order islands chains and noble barriers in a toroidal magnetic configuration

    We first remind usual physical and mathematical concepts involved in the dynamics of Hamiltonian systems, and namely in chaotic systems described by discrete 2D maps (representing the intersection points of toroidal magnetic lines in a poloidal plane in situations of incomplete magnetic chaos in Tokamaks). Finding the periodic points characterizing chains of magnetic islands is an essential step not only to determine the skeleton of the phase space picture, but also to determine the flux of magnetic lines across semi-permeable barriers like Cantori. We discuss here several computational methods used to determine periodic points in N dimensions, which amounts to solve a set of N nonlinear coupled equations: Newton method, minimization techniques, Laplace or steepest descend method, conjugated direction method and Fletcher-Reeves method. We have succeeded to improve this last method in an important way, without modifying its useful double-exponential convergence. This improved method has been tested and applied to finding periodic points of high order m in the 2D 'Tokamap' mapping, for values of m along rational chains of winding number n/m converging towards a noble value where a Cantorus exists. Such precise positions of periodic points have been used in the calculation of the flux across this Cantorus. (authors)

  17. Budgetary Impact of Cabazitaxel Use After Docetaxel Treatment for Metastatic Castration-Resistant Prostate Cancer. (United States)

    Flannery, Kyle; Drea, Ed; Hudspeth, Louis; Corman, Shelby; Gao, Xin; Xue, Mei; Miao, Raymond


    hypothetical rate of 33%, the PMPM cost would decrease to $0.524, reflecting a cost saving of $0.004 PMPM and equating to incremental savings of $49,546, or $497 per patient per year (PPPY). In the second scenario, when out-of-pocket costs were not considered, the cost of second-line treatment after docetaxel was estimated as $6,733,594, or $0.561 PMPM. With a hypothetical increase in cabazitaxel use (24%-33%), the PMPM cost would decrease to $0.554, reflecting savings of $0.007 PMPM and equating to incremental savings of $86,136, or $864 PPPY. The primary driver of cost savings with increased cabazitaxel use was lower acquisition cost. One-way sensitivity analyses revealed that the model results were robust over a wide range of input values (utilization, prevalence, and population parameters). In the presented BIM, an increase in cabazitaxel use is expected to result in modest cost savings to the health plan. Patient coinsurance savings may also be realized based on applicable Medicare Part B and Part D calculations. This BIM presents an objective, comprehensive, robust, and user-adaptable tool that health plans and medical decision makers may use to evaluate potential economic impact of formulary and reimbursement decisions.

  18. Effects of ocean acidification driven by elevated CO2 on larval shell growth and abnormal rates of the venerid clam, Mactra veneriformis (United States)

    Kim, Jee-Hoon; Yu, Ok Hwan; Yang, Eun Jin; Kang, Sung-Ho; Kim, Won; Choy, Eun Jung


    The venerid clam ( Mactra veneriformis Reeve 1854) is one of the main cultured bivalve species in intertidal and shallow subtidal ecosystems along the west coast of Korea. To understand the effects of ocean acidification on the early life stages of Korean clams, we investigated shell growth and abnormality rates and types in the D-shaped, umbonate veliger, and pediveliger stages of the venerid clam M. veneriformis during exposure to elevated seawater pCO2. In particular, we examined abnormal types of larval shell morphology categorized as shell deformations, shell distortions, and shell fissures. Specimens were incubated in seawater equilibrated with bubbled CO2-enriched air at (400±25)×10-6 (ambient control), (800±25)×10-6 (high pCO2), or (1 200±28)×10-6 (extremely high pCO2), the atmospheric CO2 concentrations predicted for the years 2014, 2084, and 2154 (70-year intervals; two human generations), respectively, in the Representative Concentration Pathway (RCP) 8.5 scenario. The mean shell lengths of larvae were significantly decreased in the high and extremely high pCO2 groups compared with the ambient control groups. Furthermore, under high and extremely high pCO2 conditions, the cultures exhibited significantly increased abundances of abnormal larvae and increased severity of abnormalities compared with the ambient control. In the umbonate veliger stage of the experimental larvae, the most common abnormalities were shell deformations, distortions, and fissures; on the other hand, convex hinges and mantle protuberances were absent. These results suggest that elevated CO2 exerts an additional burden on the health of M. veneriformis larvae by impairing early development.

    The watercolor illusion is a color spreading effect at long-range diffusing from a thin colored contour juxtaposed to a chromatic one of higher contrast and a object-hole effect across a large area (Pinna, 1987; Pinna et al., 2001, 2003; Pinna & Reeves, 2006). The watercolored figure appears evenly colored by an opaque light veil of chromatic tint (coloration effect), with a clear surface color property spreading from the lighter contour. At the same time, the watercolored figure manifests a strong figure-ground organization and a solid figural appearance comparable to a bas-relief illuminated from the top (object-hole effect). It appears similar to a rounded surface segregated in depth, which extends out from the flat surface. The complementary region appears as a hole or empty space. The phenomenal properties of coloration and object-hole effects raise some questions. Can the two effects be considered relatively independent? Under what conditions can a possible dissociation occur? How does the dissociation of one effect, say the coloration, influence the object-hole effect and vice versa? To answer these questions two new effects related to the watercolor illusion were psychophysically studied: (1) the "uneven watercolor," based on a modified watercolor figure without volumetric and three-dimensional properties but with a strong coloration effect and (2) the "watercolor surface capture," where oblique lines within a watercolor figure appear bulging, curved in depth and segregated from those that are perceived as placed in the background or perceived through holes. The results of two experiments suggest that the coloration effect can be dissociated from the object-hole one. These results are discussed in the light of a simple summation hypothesis of the underlying effects composing the whole figurality. This hypothesis can suggest further investigation both in the phenomenal and in the neurophysiological domain.

However, little is known about whether this association differs by comorbid medical condition or whether reasons for nonadherence differ by depressive symptoms or comorbid medical condition. Methods: Self-reported extent of nonadherence, reasons for nonadherence, and depressive symptoms among 1,026 veterans prescribed medications for hypertension, dyslipidemia, and/or type 2 diabetes were assessed. Results: In multivariable logistic regression adjusted for clinical and demographic factors, the odds of nonadherence were higher among participants with high depressive symptom burden for dyslipidemia (n=848; odds ratio [OR]: 1.42, P=0.03 but not hypertension (n=916; OR: 1.24, P=0.15, or type 2 diabetes (n=447; OR: 1.15, P=0.51. Among participants reporting nonadherence to antihypertensive and antilipemic medications, those with greater depressive symptom burden had greater odds of endorsing medication nonadherence reasons related to negative expectations and excessive economic burden. Neither extent of nonadherence nor reasons for nonadherence differed by depressive symptom burden among patients with diabetes. Conclusion: These findings suggest that clinicians may consider tailoring interventions to improve adherence to antihypertensive and antilipemic medications to specific medication concerns of participants with depressive symptoms

  1. Distribution of Wild Mammal Assemblages along an Urban–Rural–Forest Landscape Gradient in Warm-Temperate East Asia (United States)

    Saito, Masayuki; Koike, Fumito


    Urbanization may alter mammal assemblages via habitat loss, food subsidies, and other factors related to human activities. The general distribution patterns of wild mammal assemblages along urban–rural–forest landscape gradients have not been studied, although many studies have focused on a single species or taxon, such as rodents. We quantitatively evaluated the effects of the urban–rural–forest gradient and spatial scale on the distributions of large and mid-sized mammals in the world's largest metropolitan area in warm-temperate Asia using nonspecific camera-trapping along two linear transects spanning from the urban zone in the Tokyo metropolitan area to surrounding rural and forest landscapes. Many large and mid-sized species generally decreased from forest landscapes to urban cores, although some species preferred anthropogenic landscapes. Sika deer (Cervus nippon), Reeves' muntjac (Muntiacus reevesi), Japanese macaque (Macaca fuscata), Japanese squirrel (Sciurus lis), Japanese marten (Martes melampus), Japanese badger (Meles anakuma), and wild boar (Sus scrofa) generally dominated the mammal assemblage of the forest landscape. Raccoon (Procyon lotor), raccoon dog (Nyctereutes procyonoides), and Japanese hare (Lepus brachyurus) dominated the mammal assemblage in the intermediate zone (i.e., rural and suburban landscape). Cats (feral and free-roaming housecats; Felis catus) were common in the urban assemblage. The key spatial scales for forest species were more than 4000-m radius, indicating that conservation and management plans for these mammal assemblages should be considered on large spatial scales. However, small green spaces will also be important for mammal conservation in the urban landscape, because an indigenous omnivore (raccoon dog) had a smaller key spatial scale (500-m radius) than those of forest mammals. Urbanization was generally the most important factor in the distributions of mammals, and it is necessary to consider the spatial

  2. Offshore wind transport and installation vessel

    Energy Technology Data Exchange (ETDEWEB)



    The initial objective of the project was to complete a feasibility study to determine the viability of an innovative transportation vessel to be deployed in the installation of offshore wind farms. This included the feasibility of providing a stable-working platform that can be used in harsh offshore environments. A study of current installation contractors and their installation equipment was used to provide a preliminary specification for the installation vessel. A typical barge was selected and a number of hydrodynamic analyses were carried out in order to establish it's on course and operational stability. The analysis proved the stability of the vessel during operation was critical and that in order to utilise the crane's full potential a stabilisation system must be employed. The main aim of the work to date was to establish whether it was feasible to use a stabilisation system on the installation vessel. The spud leg FEED study established that it was feasible to use spud legs to stabilise the vessel. In order to achieve the degree of stability required it is necessary to lift the vessel completely out of the water. This was not the original aim of the study but due to the external loads on the hull it was the only viable option. Lifting the vessel out of the water results in the legs and leg casings becoming very large. This has a number of consequences for the final design. Due to large loads on the legs spud cans must be used to avoid bottom penetration, the spud cans increase the draft of the vessel by 2m. The large loads require larger winches and more reeving to be used, this results in larger pumps and motors, all of which have to be housed. The stabilisation system has been proved to be feasible for a large installation vessel, the cost and physical size are however more excessive than first anticipated. (Author)

  3. Exercising choice for national healthcare. In the end, we'll get what we choose. (United States)

    Bruder, P


    Whether we evolve toward a market model, a play-or-pay model, or a national model will depend largely upon our personal beliefs and perspectives. Unfortunately, in the hectic and fast-paced life that virtually all of us lead, we base many of our conclusions on unexamined bits and pieces of conventional wisdom. We have looked at but five of them. Yet these bits and pieces become the yardsticks by which we measure other plans and other people. Instead of listening to and studying the approaches proposed by others, we are often too quick to dismiss them with labels such as "too costly," or "too capitalist," or "too socialist," or "too whatever." As a consequence, we become prisoners of our own ideology. Would that we were more like Tillich's (1951) description of the famous theologian, Karl Barth, who "...strenuously tries not to become his own follower" (5). In other words, we would work to continually inform and correct ourselves in light of new understanding. Our healthcare problems--any social problems, for that matter--are never really solved. All we can do is do our best at meeting needs, even if it means that in meeting one set of needs we inadvertently create other needs. But that is why we are enriched when we accept the challenge of continuing to question our personal bits and pieces of conventional wisdom. In a recent column in the Houston Post, Richard Reeves cites statistical evidence, known to most who work in the healing professions, indicating that people who live alone tend to suffer from greater illness.(ABSTRACT TRUNCATED AT 250 WORDS)

  4. Nuclear HMGA1 nonhistone chromatin proteins directly influence mitochondrial transcription, maintenance, and function

    International Nuclear Information System (INIS)

    Dement, Gregory A.; Maloney, Scott C.; Reeves, Raymond


    We have previously demonstrated that HMGA1 proteins translocate from the nucleus to mitochondria and bind to mitochondrial DNA (mtDNA) at the D-loop control region [G.A. Dement, N.R. Treff, N.S. Magnuson, V. Franceschi, R. Reeves, Dynamic mitochondrial localization of nuclear transcription factor HMGA1, Exp. Cell Res. 307 (2005) 388-401.] [11]. To elucidate possible physiological roles for such binding, we employed methods to analyze mtDNA transcription, mitochondrial maintenance, and other organelle functions in transgenic human MCF-7 cells (HA7C) induced to over-express an HA-tagged HMGA1 protein and control (parental) MCF-7 cells. Quantitative real-time (RT) PCR analyses demonstrated that mtDNA levels were reduced approximately 2-fold in HMGA1 over-expressing HA7C cells and flow cytometric analyses further revealed that mitochondrial mass was significantly reduced in these cells. Cellular ATP levels were also reduced in HA7C cells and survival studies showed an increased sensitivity to killing by 2-deoxy-D-glucose, a glycolysis-specific inhibitor. Flow cytometric analyses revealed additional mitochondrial abnormalities in HA7C cells that are consistent with a cancerous phenotype: namely, increased reactive oxygen species (ROS) and increased mitochondrial membrane potential (ΔΨ m ). Additional RT-PCR analyses demonstrated that gene transcripts from both the heavy (ND2, COXI, ATP6) and light (ND6) strands of mtDNA were up-regulated approximately 3-fold in HA7C cells. Together, these mitochondrial changes are consistent with many previous reports and reveal several possible mechanisms by which HMGA1 over-expression, a common feature of naturally occurring cancers, may affect tumor progression

  5. What do dogs know about hidden objects? (United States)

    Miller, Holly C; Rayburn-Reeves, Rebecca; Zentall, Thomas R


    Previous research has found that dogs will search accurately for an invisibly displaced object when the task is simplified and contextual ambiguity is eliminated [Doré, F.Y., Fiset, S., Goulet, S., Dumas, M.-C., Gagnon, S., 1996. Search behavior in cats and dogs: interspecific differences in working memory and spatial cognition. Animal Learning & Behavior 24, 142-149; Miller, H., Gipson, C., Vaughan, A., Rayburn-Reeves, R., Zentall, T.R., 2009. Object permanence in dogs: invisible displacement in a rotation task. Psychonomic Bulletin & Review 16 (1), 150-155]. For example, when an object is placed inside an occluder, one of which was attached to each end of a beam that could be rotated 90 degrees , dogs search inside of the appropriate occluder. The current research confirmed this finding and tested the possibility that the dogs were using a perceptual/conditioning mechanism (i.e., their gaze was drawn to the occluder as the object was placed inside and they continued looking at it as it rotated). The test was done by introducing a delay between the displacement of the object and the initiation of the dogs' search. In Experiment 1, during the delay, a barrier was placed between the dog and the apparatus. In Experiment 2, the lights were turned off during the delay. The search accuracy for some dogs was strongly affected by the delay, however, search accuracy for other dogs was not affected. These results suggest that although a perceptual/conditioning mechanism may be involved for some dogs, it cannot account for the performance of others. It is likely that these other dogs showed true object permanence.

    Full Text Available Northeastern Atlantic and Mediterranean gastropods previously ascribed to the buccinid genus Pollia Gray, 1837 are more correctly classified in the genus Aplus de Gregorio, 1885. Using an integrative taxonomy approach combining molecular, morphological and geographic data, we revisit the limits of the extant species in the area, and propose a molecular phylogenetic hypothesis based on 66 specimens from various localities in the Mediterranean Sea, including type localities of some nominal taxa. We used a preliminary morphological inspection, followed by a DNA-barcoding approach to propose species hypotheses, subsequently consolidated using additional data (phylogenetic, geographic and refined morphological data. Seven species hypotheses were eventually retained within our molecularly assayed samples, versus three classical morphologically recognized species. Among these, three correspond to Aplus dorbignyi (Payreaudeau, 1826 with its hitherto unrecognized geographical cognates A. gaillardoti (Puton, 1856 (eastern Mediterranean and Aplus nodulosus (Bivona Ant., 1832 (Sicily; two closely related, yet considerably divergent, lineages are treated as a single species under Aplus scaber (Locard, 1892; the classically admitted Aplus scacchianus (Philippi, 1844 is confirmed by molecular evidence; Mediterranean populations attributable to Aplus assimilis (Reeve, 1846 may represent either cryptic native populations or an ongoing invasion of the Mediterranean by what was hitherto considered to be a West African species; finally, specimens from the Strait of Gibraltar may represent an undescribed species, but we conservatively refrain from formally introducing it pending the analysis of more material, and it is compared with the similar Aplus campisii (Ardovini, 2014, recently described from Sicily and not assayed molecularly, and Aplus scaber.

  8. The distribution of waves in the inner magnetosphere as a function of solar wind parameters (United States)

    Aryan, Homayon; Balikhin, Michael A.; Agapitov, Oleksiy; Krasnoselskikh, Vladimir; Yearby, Keith

    Energetic electrons within the Earth’s radiation belts represent a serious hazard to geostationary satellites. The interactions of electrons with chorus waves play an important role in both the acceleration and loss of radiation belt electrons. Studies of the evolution of energetic electron fluxes rely heavily on numerical codes in order to model energy and pitch angle diffusion due to electron interaction with plasma waves in the frame of quasilinear approximation. Application of these codes requires knowledge of statistical wave models to present wave distributions in the magnetosphere. A number of such models are based on CRESS, Cluster, THEMIS and other mission data. These models present wave distributions as a function of L-shell, magnetic local time, magnetic latitude and geomagnetic activity expressed by geomagnetic indices (Kp or Ae). However, it has been shown by G. Reeves and co-authors that only 50% of geomagnetic storms increase flux of relativistic electrons at GEO while 20% cause a decrease. This emphasizes the importance of including solar wind parameters in addition to geomagnetic indices. The present study examines almost four years (01, January, 2004 to 29, September, 2007) of STAFF (Spatio-Temporal Analysis of Field Fluctuation) data from Double Star TC1 combined with geomagnetic indices and solar wind parameters from OMNI database in order to present a comprehensive model of chorus wave intensities as a function of L-shell, magnetic local time, magnetic latitude, geomagnetic indices and solar wind parameters. The results show that chorus emission is not only sub-storm dependent but also dependent upon solar wind parameters with solar wind velocity evidently the most influential solar wind parameter. The largest peak intensities are observed for lower band chorus during active conditions, high solar wind velocity, low density and high pressure.

  9. Simulation of groundwater flow in the Edwards-Trinity and related aquifers in the Pecos County region, Texas (United States)

    Clark, Brian R.; Bumgarner, Johnathan R.; Houston, Natalie A.; Foster, Adam L.


    The Edwards-Trinity aquifer is a vital groundwater resource for agricultural, industrial, and public supply uses in the Pecos County region of western Texas. The U.S. Geological Survey completed a comprehensive, integrated analysis of available hydrogeologic data to develop a numerical groundwater-flow model of the Edwards-Trinity and related aquifers in the study area in parts of Brewster, Jeff Davis, Pecos, and Reeves Counties. The active model area covers about 3,400 square miles of the Pecos County region of Texas west of the Pecos River, and its boundaries were defined to include the saturated areas of the Edwards-Trinity aquifer. The model is a five-layer representation of the Pecos Valley, Edwards-Trinity, Dockum, and Rustler aquifers. The Pecos Valley aquifer is referred to as the alluvial layer, and the Edwards-Trinity aquifer is divided into layers representing the Edwards part of the Edwards-Trinity aquifer and the Trinity part of the Edwards-Trinity aquifer, respectively. The calibration period of the simulation extends from 1940 to 2010. Simulated hydraulic heads generally were in good agreement with observed values; 1,684 out of 2,860 (59 percent) of the simulated values were within 25 feet of the observed value. The average root mean square error value of hydraulic head for the Edwards-Trinity aquifer was 34.2 feet, which was approximately 4 percent of the average total observed change in groundwater-level altitude (groundwater level). Simulated spring flow representing Comanche Springs exhibits a pattern similar to observed spring flow. Independent geochemical modeling corroborates results of simulated groundwater flow that indicates groundwater in the Edwards-Trinity aquifer in the Leon-Belding and Fort Stockton areas is a mixture of recharge from the Barilla and Davis Mountains and groundwater that has upwelled from the Rustler aquifer.

  10. Design-based online teacher professional development to introduce integration of STEM in Pakistan (United States)

    Anwar, Tasneem

    In today's global society where innovations spread rapidly, the escalating focus on science, technology, engineering and mathematics (STEM) has quickly intensified in the United States, East Asia and much of Western Europe. Our ever-changing, increasingly global society faces many multidisciplinary problems, and many of the solutions require the integration of multiple science, technology, engineering, and mathematics (STEM) concepts. Thus, there is a critical need to explore the integration of STEM subjects in international education contexts. This dissertation study examined the exploration of integration of STEM in the unique context of Pakistan. This study used three-phase design-based methodological framework derived from McKenney and Reeves (2012) to explore the development of a STEM focused online teacher professional development (oTPD-STEM) and to identify the design features that facilitate teacher learning. The oTPD-STEM program was designed to facilitate eight Pakistani elementary school teachers' exploration of the new idea of STEM integration through both practical and theoretical considerations. This design-based study employed inductive analysis (Strauss and Corbin, 1998) to analyze multiple data sources of interviews, STEM perception responses, reflective learning team conversations, pre-post surveys and artifacts produced in oTPD-STEM. Findings of this study are presented as: (1) design-based decisions for oTPD-STEM, and (2) evolution in understanding of STEM by sharing participant teachers' STEM model for Pakistani context. This study advocates for the potential of school-wide oTPD for interdisciplinary collaboration through support for learner-centered practices.

  11. Online Scholarly Conversations in General Education Astronomy Courses (United States)

    Cai, Qijie; Wong, Ka-Wah


    In general education astronomy courses, many students are struggling with understanding the foundational concepts and theories in astronomy. One of the possible reasons is that, due the large class size, many of the courses are taught using a lecture mode, where human interactions and active learning are limited (Freeman et al., 2014). To address this challenge, we have applied the knowledge building framework (Scardamalia & Bereiter, 2006) to design an online collaborative learning component, called Scholarly Conversations, to be integrated into a general education astronomy course at a public, comprehensive university.During Scholarly Conversations, students are treated as scholars to advance knowledge frontiers (Scardamalia & Bereiter, 2006). The whole process involves the creation of new ideas and requires discourse and collective work for the advancement and creation of artifacts, such as theories and models (van Aalst, 2009). Based on the knowledge building principles (Scardamalia, 2002; Zhang, Scardamalia, Reeve, & Messina, 2009), several features have been built into Scholarly Conversations so that students are guided to deepen understanding of the astronomy concepts through three phases: knowledge sharing, knowledge construction and knowledge building, and reflections on learning growth (van Aalst, 2009; Cai, 2017). The online Scholarly Conversation is an extension of the lecture component of the general education astronomy course. It promotes student interactions and collaborative learning, and provides scaffolds for students to construct meanings of the essential concepts in astronomy through social learning and online technology. In this presentation, we will explain the specific design principles of the online Scholarly Conversation, and share the artifacts created to facilitate the online conversations in an general education astronomy course.Note: This project has been supported by the College of Education Research Grant Program at Minnesota State

  12. Optimizing the calculation of DM,CO and VC via the single breath single oxygen tension DLCO/NO method. (United States)

    Coffman, Kirsten E; Taylor, Bryan J; Carlson, Alex R; Wentz, Robert J; Johnson, Bruce D


    Alveolar-capillary membrane conductance (D(M,CO)) and pulmonary-capillary blood volume (V(C)) are calculated via lung diffusing capacity for carbon monoxide (DL(CO)) and nitric oxide (DL(NO)) using the single breath, single oxygen tension (single-FiO2) method. However, two calculation parameters, the reaction rate of carbon monoxide with blood (θ(CO)) and the D(M,NO)/D(M,CO) ratio (α-ratio), are controversial. This study systematically determined optimal θ(CO) and α-ratio values to be used in the single-FiO2 method that yielded the most similar D(M,CO) and V(C) values compared to the 'gold-standard' multiple-FiO2 method. Eleven healthy subjects performed single breath DL(CO)/DL(NO) maneuvers at rest and during exercise. D(M,CO) and V(C) were calculated via the single-FiO2 and multiple-FiO2 methods by implementing seven θ(CO) equations and a range of previously reported α-ratios. The RP θ(CO) equation (Reeves, R.B., Park, H.K., 1992. Respiration Physiology 88 1-21) and an α-ratio of 4.0-4.4 yielded DM,CO and VC values that were most similar between methods. The RP θ(CO) equation and an experimental α-ratio should be used in future studies. Copyright © 2015 Elsevier B.V. All rights reserved.

  13. Longitudinal Recovery and Reduced Costs After 120 Sessions of Locomotor Training for Motor Incomplete Spinal Cord Injury. (United States)

    To determine the impact of long-term, body weight-supported locomotor training after chronic, incomplete spinal cord injury (SCI), and to estimate the health care costs related to lost recovery potential and preventable secondary complications that may have occurred because of visit limits imposed by insurers. Prospective observational cohort with longitudinal follow-up. Eight outpatient rehabilitation centers that participate in the Christopher & Dana Reeve Foundation NeuroRecovery Network (NRN). Individuals with motor incomplete chronic SCI (American Spinal Injury Association Impairment Scale C or D; N=69; 0.1-45y after SCI) who completed at least 120 NRN physical therapy sessions. Manually assisted locomotor training (LT) in a body weight-supported treadmill environment, overground standing and stepping activities, and community integration tasks. International Standards for Neurological Classification of Spinal Cord Injury motor and sensory scores, orthostatic hypotension, bowel/bladder/sexual function, Spinal Cord Injury Functional Ambulation Inventory (SCI-FAI), Berg Balance Scale, Modified Functional Reach, 10-m walk test, and 6-minute walk test. Longitudinal outcome measure collection occurred every 20 treatments and at 6- to 12-month follow-up after discharge from therapy. Significant improvement occurred for upper and lower motor strength, functional activities, psychological arousal, sensation of bowel movement, and SCI-FAI community ambulation. Extended training enabled minimal detectable changes at 60, 80, 100, and 120 sessions. After detectable change occurred, it was sustained through 120 sessions and continued 6 to 12 months after treatment. Delivering at least 120 sessions of LT improves recovery from incomplete chronic SCI. Because walking reduces rehospitalization, LT delivered beyond the average 20-session insurance limit can reduce rehospitalizations and long-term health costs.

  15. Pathways over Time: Functional Genomics Research in an Introductory Laboratory Course. (United States)

    Reeves, Todd D; Warner, Douglas M; Ludlow, Larry H; O'Connor, Clare M


    National reports have called for the introduction of research experiences throughout the undergraduate curriculum, but practical implementation at many institutions faces challenges associated with sustainability, cost, and large student populations. We describe a novel course-based undergraduate research experience (CURE) that introduces introductory-level students to research in functional genomics in a 3-credit, multisection laboratory class. In the Pathways over Time class project, students study the functional conservation of the methionine biosynthetic pathway between divergent yeast species. Over the five semesters described in this study, students ( N = 793) showed statistically significant and sizable growth in content knowledge ( d = 1.85) and in self-reported research methods skills ( d = 0.65), experimental design, oral and written communication, database use, and collaboration. Statistical analyses indicated that content knowledge growth was larger for underrepresented minority students and that growth in content knowledge, but not research skills, varied by course section. Our findings add to the growing body of evidence that CUREs can support the scientific development of large numbers of students with diverse characteristics. The Pathways over Time project is designed to be sustainable and readily adapted to other institutional settings. © 2018 T. D. Reeves et al.

    Full Text Available Sachin Narain,1 Lama Al-Khoury,2 Eric Chang3–6 1Department of Anesthesiology and Perioperative Care, 2Department of Neurology, 3Department of Physical Medicine and Rehabilitation, 4Department of Neurosurgery, 5Department of Orthopedics, 6Reeve-Irvine Research Center for Spinal Cord Injury, University of California Irvine, Irvine, CA, USA Background: Migraine headaches are a common and functionally debilitating disorder affecting approximately 17% of women and 5.6% of men. Compared to episodic migraine patients, chronic migraineurs are more likely to be occupationally disabled, miss family activities, have comorbid anxiety and/or chronic pain disorders, and utilize significantly more health care dollars. Ziconotide is a calcium channel blocker used for the treatment of chronic severe pain without issues of tolerance or dependency found with opioid therapy. Case: A 59-year-old female had an intrathecal baclofen pump placed for spasticity secondary to multiple sclerosis. Her symptoms also included lower extremity neuropathic pain and severe migraine headaches with 22 migraine headache days per month. Prior treatments included nonsteroidal anti-inflammatory drugs, triptans, anticonvulsants, antihypertensives, and Botox injections which reduced her symptoms to four migraine days per month at best. While her spasticity had markedly improved with intrathecal baclofen, ziconotide was added to help her neuropathic pain complaints. Following initiation of low-dose ziconotide (1 µg/day, the patient noted both lower extremity pain improvement and complete resolution of migraine headaches resulting in zero migraine days per month. She has now been migraine free for 8 months. Conclusion: Upon review of the available literature, there are no published cases of migraine improvement with intrathecal ziconotide. This represents the first case describing resolution of migraine symptoms with low-dose ziconotide. Keywords: ziconotide, migraine, symptoms, chronic

  18. River dolphins can act as population trend indicators in degraded freshwater systems.

    Directory of Open Access Journals (Sweden)

    Samuel T Turvey

    Full Text Available Conservation attention on charismatic large vertebrates such as dolphins is often supported by the suggestion that these species represent surrogates for wider biodiversity, or act as indicators of ecosystem health. However, their capacity to act as indicators of patterns or trends in regional biodiversity has rarely been tested. An extensive new dataset of >300 last-sighting records for the Yangtze River dolphin or baiji and two formerly economically important fishes, the Yangtze paddlefish and Reeves' shad, all of which are probably now extinct in the Yangtze, was collected during an interview survey of fishing communities across the middle-lower Yangtze drainage. Untransformed last-sighting date frequency distributions for these species show similar decline curves over time, and the linear gradients of transformed last-sighting date series are not significantly different from each other, demonstrating that these species experienced correlated population declines in both timing and rate of decline. Whereas species may be expected to respond differently at the population level even in highly degraded ecosystems, highly vulnerable (e.g. migratory species can therefore display very similar responses to extrinsic threats, even if they represent otherwise very different taxonomic, biological and ecological groupings. Monitoring the status of river dolphins or other megafauna therefore has the potential to provide wider information on the status of other threatened components of sympatric freshwater biotas, and so represents a potentially important monitoring tool for conservation management. We also show that interview surveys can provide robust quantitative data on relative population dynamics of different species.

  19. Near Real-Time Dust Aerosol Detection with Support Vector Machines for Regression (United States)

    Rivas-Perea, P.; Rivas-Perea, P. E.; Cota-Ruiz, J.; Aragon Franco, R. A.


    Remote sensing instruments operating in the near-infrared spectrum usually provide the necessary information for further dust aerosol spectral analysis using statistical or machine learning algorithms. Such algorithms have proven to be effective in analyzing very specific case studies or dust events. However, very few make the analysis open to the public on a regular basis, fewer are designed specifically to operate in near real-time to higher resolutions, and almost none give a global daily coverage. In this research we investigated a large-scale approach to a machine learning algorithm called "support vector regression". The algorithm uses four near-infrared spectral bands from NASA MODIS instrument: B20 (3.66-3.84μm), B29 (8.40-8.70μm), B31 (10.78-11.28μm), and B32 (11.77-12.27μm). The algorithm is presented with ground truth from more than 30 distinct reported dust events, from different geographical regions, at different seasons, both over land and sea cover, in the presence of clouds and clear sky, and in the presence of fires. The purpose of our algorithm is to learn to distinguish the dust aerosols spectral signature from other spectral signatures, providing as output an estimate of the probability of a data point being consistent with dust aerosol signatures. During modeling with ground truth, our algorithm achieved more than 90% of accuracy, and the current live performance of the algorithm is remarkable. Moreover, our algorithm is currently operating in near real-time using NASA's Land, Atmosphere Near real-time Capability for EOS (LANCE) servers, providing a high resolution global overview including 64, 32, 16, 8, 4, 2, and 1km. The near real-time analysis of our algorithm is now available to the general public at and archives of the results starting from 2012 are available upon request.

  20. A detailed survey of numerical methods for unconstrained minimization. Pt. 1

    Mika, K.; Chaves, T.


    A detailed description of numerical methods for unconstrained minimization is presented. This first part surveys in particular conjugate direction and gradient methods, whereas variable metric methods will be the subject of the second part. Among the results of special interest we quote the following. The conjugate direction methods of Powell, Zangwill and Sutti can be best interpreted if the Smith approach is adopted. The conditions for quadratic termination of Powell's first procedure are analyzed. Numerical results based on nonlinear least squares problems are presented for the following conjugate direction codes: VA04AD from Harwell Subroutine Library and ZXPOW from IMSL, both implementations of Powell's second procedure, DFMND from IBM-SILMATH (Zangwill's method) and Brent's algorithm PRAXIS. VA04AD turns out to be superior in all cases, PRAXIS improves for high-dimensional problems. All codes clearly exhibit superlinear convergence. Akaike's result for the method of steepest descent is derived directly from a set of nonlinear recurrence relations. Numerical results obtained with the highly ill conditioned Hilbert function confirm the theoretical predictions. Several properties of the conjugate gradient method are presented and a new derivation of the equivalence of steepest descent partan and the CG method is given. A comparison of numerical results from the CG codes VA08AD (Fletcher-Reeves), DFMCG (the SSP version of the Fletcher-Reevens algorithm) and VA14AD (Powell's implementation of the Polak-Ribiere formula) reveals that VA14AD is clearly superior in all cases, but that the convergence rate of these codes is only weakly superlinear such that high accuracy solutions require extremely large numbers of function calls.

    The current sheet that extends from the top of flare loops and connects to an associated flux rope is a common structure in models of coronal mass ejections (CMEs). To understand the observational properties of CME current sheets, we generated predictions from a flare/CME model to be compared with observations. We use a simulation of a large-scale CME current sheet previously reported by Reeves et al. This simulation includes ohmic and coronal heating, thermal conduction, and radiative cooling in the energy equation. Using the results of this simulation, we perform time-dependent ionization calculations of the flow in a CME current sheet and construct two-dimensional spatial distributions of ionic charge states for multiple chemical elements. We use the filter responses from the Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory and the predicted intensities of emission lines to compute the count rates for each of the AIA bands. The results show differences in the emission line intensities between equilibrium and non-equilibrium ionization. The current sheet plasma is underionized at low heights and overionized at large heights. At low heights in the current sheet, the intensities of the AIA 94 Å and 131 Å channels are lower for non-equilibrium ionization than for equilibrium ionization. At large heights, these intensities are higher for non-equilibrium ionization than for equilibrium ionization inside the current sheet. The assumption of ionization equilibrium would lead to a significant underestimate of the temperature low in the current sheet and overestimate at larger heights. We also calculate the intensities of ultraviolet lines and predict emission features to be compared with events from the Ultraviolet Coronagraph Spectrometer on the Solar and Heliospheric Observatory, including a low-intensity region around the current sheet corresponding to this model

  2. Rapidly shifting baselines in Yangtze fishing communities and local memory of extinct species. (United States)

    Local ecological knowledge can provide a unique source of data for conservation, especially in efforts to investigate the status of rare or possibly extinct species, but it is unlikely to remain constant over time. Loss of perspective about past ecological conditions caused by lack of communication between generations may create "shifting baseline syndrome," in which younger generations are less aware of local species diversity or abundance in the recent past. This phenomenon has been widely discussed, but has rarely been examined quantitatively. We present new evidence of shifting baselines in local perception of regional species declines and on the duration of "community memory" of extinct species on the basis of extensive interviews with fishers in communities across the middle-lower Yangtze basin. Many Yangtze species have experienced major declines in recent decades, and the Yangtze River dolphin or baiji (Lipotes vexillifer) and Yangtze paddlefish (Psephurus gladius) may have become extinct during the 21(st) century. Although informants across all age classes were strongly aware of the Yangtze ecosystem's escalating resource depletion and environmental degradation, older informants were more likely to recognize declines in two commercially important fish species, Reeves' shad (Tenualosa reevesii) and Yangtze pufferfish (Takifugu fasciatus), and to have encountered baiji and paddlefish in the past. Age was also a strong predictor of whether informants had even heard of baiji or paddlefish, with younger informants being substantially less likely to recognize either species. A marked decrease in local knowledge about the Yangtze freshwater megafauna matched the time of major population declines of these species from the 1970s onwards, and paddlefish were already unknown to over 70% of all informants below the age of 40 and to those who first started fishing after 1995. This rapid rate of cultural baseline shift suggests that once even megafaunal species cease to

J2-C3 was identified to be a homogeneous compound by native polyacrylamide gel electrophoresis (Native-PAGE. The purity of J2-C3 was over 99% in reversed phase-high performance liquid chromatography (RP-HPLC. The molecular weight was determined as 20,538.0 Da by electrospray-ionization mass spectrometry (ESI-MS/MS. J2-C3 was rich in Glx (Gln + Glu, Lys, and Asx (Asp + Asn according to amino acid analysis. Four partial amino acid sequences of this peptide were determined as L/ISMEDVEESR, KNGMHSI/LDVNHDGR, AMKI/LI/LNPKKGI/LVPR and AMGAHKPPKGNEL/IGHR via MALDI-TOF/TOF-MS and de novo sequencing. Secondary structural analysis by CD spectroscopy revealed that J2-C3 had the α-helix (45.2%, β-sheet (2.9%, β-turn (26.0% and random coil (25.9%. The anti-tumor effect of J2-C3 against human tumor cells was measured by 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT assay, and the IC50 values of J2-C3 were 65.57, 93.33 and 122.95 µg/mL against A549, HT-29 and HepG2 cell lines, respectively. Therefore, J2-C3 might be developed as a potential anti-tumor agent.

    Chien, Jung-Tsun; Shen, San-Tai; Lin, Yao-Sung; Yu, John Yuh-Lin


    Follicle-stimulating hormone (FSH) is a member of the pituitary glycoprotein hormone family. These hormones are composed of two dissimilar subunits, alpha and beta. Very little information is available regarding the nucleotide and amino acid sequence of FSHbeta in reptilian species. For better understanding of the phylogenetic diversity and evolution of FSH molecule, we have isolated and sequenced the complementary DNA (cDNA) encoding the Chinese soft-shell turtle (Pelodiscus sinensis, Family of Trionychidae) FSHbeta precursor molecule by reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA end (RACE) methods. The cloned Chinese soft-shell turtle FSHbeta cDNA consists of 602-bp nucleotides, including 34-bp nucleotides of the 5'-untranslated region (UTR), 396-bp of the open reading frame, and 3'-UTR of 206-bp nucleotides. It encodes a 131-amino acid precursor molecule of FSHbeta subunit with a signal peptide of 20 amino acids followed by a mature protein of 111 amino acids. Twelve cysteine residues, forming six disulfide bonds within beta-subunit and two putative asparagine-linked glycosylation sites, are also conserved in the Chinese soft-shell turtle FSHbeta subunit. The deduced amino acid sequence of the Chinese soft-shell turtle FSHbeta shares identities of 97% with Reeves's turtle (Family of Bataguridae), 83-89% with birds, 61-70% with mammals, 63-66% with amphibians and 40-58% with fish. By contrast, when comparing the FSHbeta with the beta-subunits of the Chinese soft-shell turtle luteinizing hormone and thyroid stimulating hormone, the homologies are as low as 38 and 39%, respectively. A phylogenetic tree including reptilian species of FSHbeta subunits, is presented for the first time. Out of various tissues examined, FSHbeta mRNA was only expressed in the pituitary gland and can be up-regulated by gonadotropin-releasing hormone in pituitary tissue culture as estimated by fluorescence real-time PCR analysis.

  6. Water exchange in raised bogs: revised views especially in relation to biogeochemistry (United States)

    Sirin, Andrey; Kravchenko, Irina; Yurova, Alla; Markina, Anastasiya


    Raised bogs are one of the most common and exciting mire type within the boreal zone and appear in the other zones including mountain regions in the tropics. They receive water and nutrients from the atmosphere and pore water stored in their domes is spaced above the surrounding area (up to 10 m in height). Traditionally it is assumed that water flow occurs mainly in a peat layer near to the surface and water transport is negligible in deeper layers (lvanov, 1981; Ingram, 1982; etc.). The «acrotelm/catotelm» paradigm on active and inert horizons for the peat above and below the lowest water level is still widely spread in peatland hydrology. However, recent studies have shown that deep water movement is much more dynamic in raised bogs than was previously thought (Sirin et al., 1997, Reeve et al., 2000; etc.). Relying on isotope studies we conclude that all the mounded strata of the raised bogs have relatively active water exchange although water residence time changes with depth. The study included two raised bogs, representing different typical hydrological conditions (underlain by outwash sands and moraine clay) at the Zapadnaya Dvina Peatland Field Station of the Institute of Forest Science RAS located 400 km west of Moscow (56 N, 32 E). Peatlands, among which raised bogs dominate, constitute > 30% of the area, and maximum peat thickness exceeds 7 m. To evaluate water residence time in peat strata specially determined mathematical model which include the equations of water mass and tritium balance, imbedded in a conceptual framework of water dynamics within a raised bog peat body, have been developed and tested. The results from isotope studies (3H, 18O, 2H) were additionally supported by geochemical (pH, Eh, electrical conductivity) and temperature long term monitoring, as well as dissolved CO2 and CH4 monitoring within vertical profiles of the studied raised bogs (Sirin et al., 1998). Later it was also supported by microbiology data of methane cycle in the

    Rice (Oryza sativa), has been considered the best staple food among all cereals and is the staple food for over 3 billion people, constituting over half of the world's population (Cantral and Reeves, 2002). In this study, elemental, isotopic and proximate analyses were done on rice samples in a attempt to establish variances between Philippine and Japanese rice, which can be useful for geographical authenticity testing. Rice samples were collected in Japan and in the Philippines (market survey samples from Metro Manila, and farm harvests from Aklan province). The samples were washed, dried and ground to fine powder. Instrumental neutron activation analysis (INAA), a very sensitive non-destructive multi-element analytical technique, was used for the elemental analysis of the samples and isotope-ratio mass spectrometry (IRMS) was used to obtain the isotopic signatures of the samples. Proximate analysis (AOAC procedure) was used to determine nutrient aggregates. Results show that compared with the unpolished rice standard NIES CRM10b, the polished Japanese and Philippine rice sampled show reduced concentrations of elements by as much as 1/10, 1/4, 1/5 and 1/3 for Mg, Mn, K and Na, respectively. Levels of Ca and Zn are not greatly affected. Arsenic is found in all the Japanese rice tested at an average concentration of 0.103 μg/g and three out of four of the Philippine rice at an average concentration of 0.070 μg/g. Arsenic contamination may have been introduced from the fertilizer used in rice fields. Higher levels of Br are seen in two of the Philippine rice at 14 and 34 μg/g with the most probable source being the pesticide methyl bromide. The rice samples from Aklan showed inter-variety variability in composition (70 to 85 % carbohydrates, 0.5 to 3.0 % fat and 4 to 5 % protein) which makes it difficult to establish provenance in terms of proximate composition. Isotopic ratio of δ 13 C show signature that of a C3 plant with possible narrow distinguishable

This also applies to medicines, given their ubiquity as health care interventions. Patients’ experiences of using medicines vary, and instruments which measure these are seen as an essential component to improve care. We aimed to identify generic measures of patients’ experiences of using prescription medicines and to examine their properties and suitability for use in research or practice. Methods: Multiple electronic databases were searched: MEDLINE, Embase, PsycINFO, PsycARTICLES, CINHAL Plus, PROQOLID®, and Google Scholar. We identified, critically appraised, and summarized generic questionnaires assessing one or more aspects of the medicine use experience among adult patients using prescription medicines for chronic conditions, and the process of questionnaire development, degree of patient involvement, and/or validation processes. Results: Fifteen questionnaires were included. Of these, nine measures were multidimensional, covering various aspects of medicine use. Six instruments covered only a single domain, assessing a specific facet of using medicines. Domains covered were the following: effectiveness; convenience, practicalities, and/or managing medicines; information, knowledge, and/or understanding; side effects; relationships and/or communication with health professionals; impact on daily living and/or social life; general satisfaction; attitudes; beliefs, concerns, and/or perceptions; medical follow-up and/or adherence-related issues; treatment- and/or medicine-related burden, perceived control, or autonomy; self-confidence about medicine use; availability and accessibility; and medicine

    This report summarizes the results of an environmental survey conducted at sites associated with the proposed Uranium Processing Facility (UPF) at the Y-12 National Security Complex in September-October 2009. The survey was conducted in order to evaluate potential impacts of the overall project. This project includes the construction of a haul road, concrete batch plant, wet soil storage area and dry soil storage area. The environmental surveys were conducted by natural resource experts at ORNL who routinely assess the significance of various project activities on the Oak Ridge Reservation (ORR). Natural resource staff assistance on this project included the collection of environmental information that can aid in project location decisions that minimize impacts to sensitive resource such as significant wildlife populations, rare plants and wetlands. Natural resources work was conducted in various habitats, corresponding to the proposed areas of impact. Thc credentials/qualifications of the researchers are contained in Appendix A. The proposed haul road traverses a number of different habitats including a power-line right-of-way. wetlands, streams, forest and mowed areas. It extends from what is known as the New Salvage Yard on the west to the Polaris Parking Lot on the east. This haul road is meant to connect the proposed concrete batch plant to the UPF building site. The proposed site of the concrete batch plant itself is a highly disturbed fenced area. This area of the project is shown in Fig. 1. The proposed Wet Soils Disposal Area is located on the north side of Bear Creek Road at the former Control Burn Study Area.

    Full Text Available This paper aims to question the living conditions of disabled people in the 21st century from  the framework of social justice. The concept of “social justice” has a long history, influenced  by the works of numerous writers including Rawls (1971, Miller (1999, Reeves (2005, Fainstein (2009, Marcuse (2009 and Harvey (1992, 2009 and by the recent debates on  inequality, diversity, segregation, exclusion, and discrimination. The debates on segregation, exclusion and discrimination are generally focused on inequalities in terms of economic,  ethnic and gender dimensions; however, in these debates, there is very little reference to unequal opportunities of disabled people. On the other hand, the diversity issue is generally discussed with respect to ethnic and cultural elements, again with very little concern for the  rights of disabled people. In many developing countries, including Turkey, a legal framework  for addressing disability issues has started to be put in place. Awareness among governments and society of the needs and rights of people with disabilities is growing. In the  last decade in Turkey, the difficulties faced by disabled people have started to be taken into  consideration seriously. Before that, the only information about the disabled population could  be obtained from General Population Census in Turkey. In 2002 “Turkey Disability Survey” was carried out collectively by the State Institute of Statistics and the Presidency of  Administration on Disabled People. In this survey, it has been targeted to estimate the number of disabled people and comprehend their socio-economic characteristics, their  problems in social life, expectations, types and causes of disability, regional differences and also the proportion of population having chronic illnesses. After this survey, many projects  have started to be realized in order to propose strategies for eliminating discrimination in  Turkey. In this paper, we will

  14. Examining Relativistic Electron Loss in the Outer Radiation Belt (United States)

    Green, J. C.; Onsager, T. G.; O'Brien, P.


    Since the discovery of earth's radiation belts researchers have sought to identify the mechanisms that dictate the seemingly erratic relativistic electron flux levels in the outer belt. Contrary to intuition, relativistic electron flux levels do not always increase during geomagnetic storms even though these storms signify enhanced energy input from the solar wind to the magnetosphere [Reeves et al., 2003; O'Brien et al., 2001]. The fickle response of the radiation belt electrons to geomagnetic activity suggests that flux levels are determined by the outcome of a continuous competition between acceleration and loss. Some progress has been made developing and testing acceleration mechanisms but little is known about how relativistic electrons are lost. We examine relativistic electron losses in the outer belt focusing our attention on flux decrease events of the type first described by Onsager et al. [2002]. The study showed a sudden decrease of geosynchronous >2MeV electron flux occurring simultaneously with local stretching of the magnetic field. The decrease was first observed near 15:00 MLT and progressed to all local times after a period of ˜10 hours. Expanding on the work of Onsager et al. [2002], we have identified ˜ 51 such flux decrease events in the GOES and LANL data and present the results of a superposed epoch analysis of solar wind data, geomagnetic activity indicators, and locally measured magnetic field and plasma data. The analysis shows that flux decreases occur after 1-2 days of quiet condition. They begin when either the solar wind dynamic pressure increases or Bz turns southward pushing hot dense plasma earthward to form a partial ring current and stretched magnetic field at dusk. Adiabatic electron motion in response to the stretched magnetic field may explain the initial flux reduction; however, often the flux does not recover with the magnetic field recovery, indicating that true loss from the magnetosphere is occurring.

Discrete choice experiments are increasingly used to reveal preferences about new health services; however, selecting appropriate attributes that describe a new health service is imperative to ensure validity of the choice experiment.Objective: To identify important factors that are relevant to Malawian women’s preferences for breast cancer detection services and to select attributes and levels for a discrete choice experiment in a setting where both breast cancer early detection and choice experiments are rare.Methods: We reviewed the literature to establish an initial list of potential attributes and levels for a discrete choice experiment and conducted qualitative interviews with health workers and community women to explore relevant local factors affecting decisions to use cancer detection services. We tested the design through cognitive interviews and refined the levels, descriptions, and designs.Results: Themes that emerged from interviews provided critical information about breast cancer detection services, specifically, that breast cancer interventions should be integrated into other health services because asymptomatic screening may not be practical as an individual service. Based on participants’ responses, the final attributes of the choice experiment included travel time, health encounter, health worker type and sex, and breast cancer early detection strategy. Cognitive testing confirmed the acceptability of the final attributes

  16. Forestry practices and aquatic biodiversity: Fish (United States)

    Gresswell, Robert E.


    In the Pacific Northwest, fish communities are found in a diverse array of aquatic habitats ranging from the large coastal rivers of the temperate rainforests, to the fragmented and sometimes ephemeral streams of the xeric interior basins, and high-elevation streams and lakes in the mountainous areas (Rieman et al. 2003). Only high-elevation lakes and streams isolated above barriers to fish passage remained historically devoid of fish because they were never invaded following Pleistocene glaciation (Smith 1981). Despite this widespread distribution and once great population abundances, taxonomic diversity of fishes in these forested systems is naturally lower than in aquatic habitats in the eastern U.S. (Reeves, Bisson, and Dambacher 1998). Interactions among factors that influence species richness in aquatic systems (e.g., basin size, long-term stability of habitat, and barriers to colonization; Smith 1981) continue to influence the occurrence and persistence of fishes in these systems today. Consequently, the larger low-elevation rivers and estuaries support the greatest variety of fish species. In the high-elevation tributary streams, fish communities are less complex because these aquatic systems were less climatically and geologically stable, and fish populations were smaller and more prone to local extirpation. Furthermore, barriers to fish passage inhibited dispersal and colonization (Smith 1981). Streams in forested landscapes generally support salmon and trout, Oncorhynchus spp., whitefish Prosopium spp., sculpins Cottus spp., suckers Catostomus spp., and minnows (Cyprinidae), but in some of the colder streams, chars (e.g., Salvelinus confluentus and Salvelinus malma) and lampreys (Petromyzontidae)may also occur (Rieman et al. 2003).Although biodiversity defined in terms of fish species richness is low in the Pacific Northwest, intraspecific variability is high, and polytypic fish species are common in the diverse aquatic habitats of the region.

    of hydrogen energy technologies to non-traditional audiences. These activities were also designed to raise the visibility of the DOE Hydrogen Program to new audiences and to help the program continue to advance its mission and vision. We believe that the work conducted under this cooperative agreement was successful at meeting the objectives presented and funded over the period of performance. During Phase 1, SENTECHs activities resulted in the development and distribution of two glossy brochures that target the on-site distributed generation and public transit markets for hydrogen energy technologies; face-to-face industry outreach meetings with various firms with an interest in hydrogen energy, but who may not have made a commitment to be involved; and implementation of two educational forums on hydrogen for students - the future engineers, technicians, and energy consumers. The educational forums were conducted with in-kind cost-shared contributions from NHA and Dr. Robert Reeves, Professor Emeritus, Rensealler During Phase 2, SENTECH activities initially were focused on the development of additional brochures and the development of a series of training modules. This set of information dissemination activities built on the experience demonstrated in our phase one activities, and focused the effort within two critical issue areas facing the development of hydrogen as an energy carrier--effective communications and information dissemination on codes and standards. SENTECH joined with the National Fire Protection Association (NFPA) to scope out the training modules and identified a series of 12 that could be used to train a variety of audiences. The NFPA is an international nonprofit corporation, which has developed a reputation as a worldwide leader in providing fire, electrical, and life safety to the public since 1896. Its membership totals more than 75,000 individuals from around the world and in more than 80 national trade and professional organizations.

  18. Regional groundwater-flow model of the Lake Michigan Basin in support of Great Lakes Basin water availability and use studies (United States)

    . Lastly, it describes several categories of limitations and discusses ways of extending the regional model to address issues at the local scale. Results of the simulations portray a regional groundwater-flow system that, over time, has largely maintained its natural predevelopment configuration but that locally has been strongly affected by well withdrawals. The quantity of rainfall in the Lake Michigan Basin and adjacent areas supports a dense surface-water network and recharge rates consistent with generally shallow water tables and predominantly shallow groundwater flow. At the regional scale, pumping has not caused major modifications of the shallow flow system, but it has resulted in decreases in base flow to streams and in direct discharge to Lake Michigan (about 2 percent of the groundwater discharged and about 0.5 cubic foot per second per mile of shoreline). On the other hand, well withdrawals have caused major reversals in regional flow patterns around pumping centers in deep, confined aquifers - most noticeably in the Cambrian-Ordovician aquifer system on the west side of Lake Michigan near the cities of Green Bay and Milwaukee in eastern Wisconsin, and around Chicago in northeastern Illinois, as well as in some shallow bedrock aquifers (for example, in the Marshall aquifer near Lansing, Mich.). The reversals in flow have been accompanied by large drawdowns with consequent local decrease in storage. On the west side of Lake Michigan, groundwater withdrawals have caused appreciable migration of the deep groundwater divides. Before the advent of pumping, the deep Lake Michigan groundwater-basin boundaries extended west of the Lake Michigan surface-water basin boundary, in some places by tens of miles. Over time, the pumping centers have replaced Lake Michigan as the regional sink for the deep flow system. The regional model is intended to support the framework pilot study of water availability and use for the Great Lakes Basin (Reeves, in press).

  19. Survey on Cosmogenic 26Al in Lewis Cliff Meteorites (United States)

    levels of 56 +- 7 and 60 +- 7 for H and L chondrites, respectively [3], range up to 800 ka with an average of about 290 ka. Altogether this may indicate that the Lewis Cliff blue-ice region is a relatively old meteorite stranding area. This is supported by preliminary conclusions based on ^36Cl, measured in 8 Lewis Cliff meteorites [4]. However, it is likely that some of our terrestrial ages have been overestimated due to (i) lower ^26Al saturation values for meteorites with preatmospheric radii less than 20 cm [3] and (ii) low exposure ages, resulting in initial ^26Al levels below 90-95% of the saturation level. These effects make individual terrestrial age determinations solely based on ^26Al content speculative as long as additional cosmogenic nuclide data are lacking. Dramatic changes in the overall picture are not expected, because (i) we have measured relatively large samples with an average recovered weight of about 500 g (one 11-kg sample excluded) and (ii) anomalously low exposure ages occur in about only 5% of the cases [5,6]. Possible correlations between terrestrial age and place of find will be discussed.

    particular, our simulations suggest that slow EHs (which generation is usually attributed to the Buneman instability) can arise due to slowing down of fast EH generated by electron-beam instability. The estimate of the potential drop along EHs allow to estimate the parallel potential drop provided by EHs in a particular plasma system. 1. Matsumoto, H., H. Kojima, T. Miyatake, Y. Omura, M.

  1. Environmental Chemical Analysis (by B. B. Kebbekus and S. Mitra) (United States)

    Bower, Reviewed By Nathan W.


    This text helps to fill a void in the market, as there are relatively few undergraduate instrumental analysis texts designed specifically for the expanding population of environmental science students. R. N. Reeve's introductory, open-learning Environmental Analysis (Wiley, 1994) is one of the few, and it is aimed at a lower level and is less appropriate for traditional classroom study. Kebbekus and Mitra's book appears to be an update of I. Marr and M. Cresser's excellent 1983 text by the same name (and also published under the Chapman and Hall imprint). It assumes no background in instrumental methods of analysis but it does depend upon a good general chemistry background in kinetic and equilibrium calculations and the standard laboratory techniques found in a classical introduction to analytical chemistry. The slant taken by the authors is aimed more toward engineers, not only in the choice of topics, but also in how they are presented. For example, the statistical significance tests presented follow an engineering format rather than the standard used in analytical chemistry. This approach does not detract from the book's clarity. The writing style is concise and the book is generally well written. The earlier text, which has become somewhat of a classic, took the unusual step of teaching the instruments in the context of their environmental application. It was divided into sections on the "atmosphere", the "hydrosphere", the "lithosphere", and the "biosphere". This text takes a similar approach in the second half, with chapters on methods for air, water, and solid samples. Users who intend to use the book as a text instead of a reference will appreciate the addition of chapters in the first half of the book on spectroscopic, chromatographic, and mass spectrometric methods. The six chapters in these two parts of the book along with four chapters scattered throughout on environmental measurements, sampling, sample preparation, and quality assurance make a nice

    Delta O18/16 data would more readily respond to solar influences. This raises the suspicion that perhaps they do not only reflect temperatures but also solar activity, as well as other possible factors not directly related to atmospheric temperatures. These methodologies may be useful as exploratory tools, directing the attention to specific areas where further research should be required. This could be the case of the Delta O18/16 data, frequently considered to be a reliable and accurate proxy of temperatures. c) Another experiment was made using daily maximum temperatures from 10 Spanish meteorological stations for the period 1901-2005 [3]. Using a hybrid procedure (Differential Evolution and Fletcher-Reeves Classical Optimization) it was found that a subset was capable of preserving the 10-dimensional similarity when nonlinearly mapped into 1D. A daily index, F1 was applied to the whole dataset and grouped by years and transformed into a Kolmogorov-Smirnov dissimilarity matrix, space optimized and clustered giving the following landmarks: 1911-12, 1919-1920, 1960, 1973 and 1989. A visual comparison with the aa geomagnetic index may suggest a certain coupling with changes in the magnetic field behavior. The complexity of the patterns suggest that the possible relationships between Earth's climate and solar activity may occur in much more complex ways than just irradiance variations and simple linear correlations.

  3. Europe's Astronomy Teachers Meet at ESO (United States)


    European Association for Astronomy Education Formed A joint EU/ESO Workshop (1) on the Teaching of Astronomy in Europe was held at the ESO Headquarters from November 25-30, 1994, under the auspices of the 1994 European Week for Scientific Culture. More than 100 teachers from secondary schools in 17 European countries participated together with representatives of national ministries and local authorities, as well as professional astronomers. This meeting was the first of its kind ever held and was very successful. As a most visible and immediate outcome, the participants agreed to form the "European Association for Astronomy Education (EAAE)", uniting astronomy educators all over Europe into one network. A provisional Executive Committee of the EAAE was elected which will work towards the organisation of a constitutional conference within the next year. The participants unanimously adopted a "Declaration on the Teaching of Astronomy in Europe", specifying the overall aims and initial actions needed to achieve them. Astronomy: Science, Technology and Culture At the beginning of the Workshop the participants listened to lectures by several specialists about some of the most active fields of astronomy. The scientific sessions included topics as diverse as minor bodies in the solar system, nucleosynthesis, interstellar chemistry and cosmology. Then followed overviews of various recent advances in astronomical technology, some of which are already having direct impact on highly specialized sectors of European industry. They included the advanced use of computers in astronomy, for instance within image processing and data archiving, as well as a demonstration of remote observing. Discussing the cultural aspects, Nigel Calder (UK) and Hubert Reeves (France) emphasized the important role of astronomy in modern society, in particular its continuing influence on our perceptions of mankind's unique location in time and space.

    continues to increase) and allewiate world hunger is to increase the intensity of production in those ecosystems that lend themselves to sustainable intensification while decreasing the intensity of production in the more fragile ecologies (Reeves 1998). Most plants depend entirely for growth on fixed nitrogen absorbed from the soil, mainly as nitrate but also as ammonium. Therefore to the methods of crop production now dominant in the agricultural systems of many developed countries strongly depend upon a sustained input of N. Economic and environmental considerations surrounding fertilizer use then empasize the need to increase the efficiency of N- utilization by plants. On the other hand the biological nitrogen fixation (BNF) is important under all imput conditions to ensure an optimal supply of nitrogen to the farming system. A well-founded understanding of the mechanistic interactions between BNF and N limitations is presently lacking. Synbiotic nitrogen fixation by legumes makes a valuable contribution to N-inputs, especially in countries like Hungary where effective rhizobia-inoculation techniques have been developed in the context of the new sustainable agricultural system. It is widely known that soya bean -Glycine max (L.) Merr.-, is an important legume. This plant able to fix the atmospheric nitrogen (N2) it needs for growth through the agency of specific bacteria Rhizobium japonicum. Under field conditions fixation usually accounts for only 25-30% of the total nitrogen accumulated by these plants at harvest. Therefore to marginal yield have to optimalise the nitrogen supply of these legume by N-fertilization. Objectives for our experiments were to (1.) comparisons of the plant nutrition performance of different soil nitrogen supply levels by N- fertilization and N- fixation under Mediterranean climate conditions at Hungary, (2.) evaluates the potential for N2 fixation imputs by grain legume based on the soya bean as a means of improving soil fertility, (3

    shared Ed's moral disapproval. His 21 year term as the astrophysics member of the editorial board of Reviews of Modern Physics (1971-92) remains a record and arose from a combination of extremely good judgment and patience with authors, referees, and other editors. His experience as a member of the National Science Board (1978-84) was a less happy one, and he felt he had not been an effective one when the NSF decided to back out of supporting a national-facility large millimeter dish, leaving that territory to individual university groups and the Europeans. How many students did Ed Salpeter have? Well, lots. He was advisor or committee chair for students in computer and geological sciences as well as in physics and astronomy, and was sometimes part of teams he called "two chiefs and one Indian" for additional students. No complete list seems to exist, but the incomplete lists add up to at least 55. Of those, you are likely to have heard of or know (because we do!): Hubert Reeves (who has great-grandstudents of his own!), George Helou, Vahe Petrosian, Bill Newman, Nathan Krumm, Bruce Tarter, Jonathan Katz, Lars Bildsten, Allen Boozer, Bruce Draine, Robert Gould, Nicolas Krall, Richard Lovelace, David Stevenson, Hugh Van Horn, Lyle Hoffman, and Edvige Corbelli. Thus he lived to achieve that mark of maturity, being invited to retirement parties for ones students. Former students, collaborators, and all spoke uniformly of his generosity, quick understanding, and willingness to discuss science on any and all occasions. Among the honors Ed Salpeter received were four honorary D.Sc.'s, five academy memberships, and major prizes from the Royal Astronomical Society, the American Astronomical Society, the Astronomical Society of the Pacific, the American Physical Society, the Royal Swedish Academy, and the Astronomische Gesellschaft (AG). The text of his AG lecture was published in English, but he told one of us that he felt he no longer had a native language, because he couldn

    new gamma-ray satellite, called `Swift', will be launched as part of a collaboration between the USA, United Kingdom and Italy. Swift will add to the flotilla of satellites providing fast and accurate locations of gamma-ray bursts on the sky, which can then be followed with XMM-Newton. This will provide even more opportunities for new discoveries in this cutting-edge field.

    American Association of Variable Star Observers, where MMO papers still turn up, though perhaps not so many as in Dorrit's day. She would also continue education and public outreach activities in the local community that her predecessor, Margaret Harwood, had established. Summer research experience for undergraduate opportunities have become common, but they were rare in 1957, especially for women students, and the ones who came to MMO (more than one hundred over her term) were undoubtedly very strongly motivated. They left even more so, with the striking result that about 25 of the Hoffleit students became professional astronomers. A few of the earliest are now retired; many remain in stellar astronomy, but others have spread across the Solar System and the galaxies. According to a list compiled by Dorrit, with minor additions, these are, in chronological order: Margo Friedel Aller, Andrea Knudsen Dupree, Barbara Welther, Gretchen Luft Hagen Harris, Nancy Houk, Martha Safford Hanner, Diane Reeve Moorhead, Nancy Remage Evans, Catherine Doremus Garmany, Jane Turner, Jean Warren Goad, Karen Alper Castle, Marcia Keyes Rieke, Judy Karpen, Karen Kwitter, Esther Hu, Bonnie Buratti, Harriet Dinerstein, Melissa McGrath, Constance Phillips Walker, John Briggs, Deborah Crocker, Edward Morgan, and Karen Meech. The program went co-ed shortly before Dorrit handed it over to Emilia Belaserne). A special paragraph must go to Janet Akyüz Mattei. She came to MMO in the summer of 1969 upon the recommendation of Paris Pismis, an Armenian-Turkish-Mexican astronomer who had known Janet in Turkey and was a very old friend of Dorrit's (and of mine). Janet's own obituary sadly appeared in these pages (BAAS, 36, pp. 1681-82, 2004), the last 30 of her only 61 years having been spent as the director of AAVSO. Among the many important things Janet did in that directorial capacity was to persuade Dorrit Hoffleit to write up the story of her life for publication by AAVSO in 2002, from which much of
