    Park, Nansook; Seligman, Martin E P


    Presents an obituary for Christopher M. Peterson. "Other people matter. Period," said Christopher M. Peterson when asked for a concise definition of "positive psychology," the field he helped to found and then helped to guide through the first decade of the 21st century. He researched, taught, and lived positive psychology. When Chris died prematurely on October 9, 2012, in Ann Arbor, Michigan, from sudden heart failure, the world lost a distinguished scholar, an inspirational teacher, and a wonderful human being. Chris loved people. He was genuinely interested in getting to know others. He made everyone around him feel comfortable and respected. An understated, humble, and generous person, it was no accident that his nickname was "Mother Theresa." He always found joy in letting other people shine and sharing the credit with them. He had a gift for seeing the best in each person. He also had a strong sense of fairness and duty without being rigid or allowing his personal feelings to obscure his judgment. He had fun whatever he did and brought fun for others. Although his scholarly contributions are significant, his lasting legacy will be what he shared with other people. So many of us are indebted to him for making us better researchers, better teachers, and better people. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

  7. Effects of encoding strategy, presentation modality, and scoring method on STM performance with the Peterson and Peterson technique. (United States)

    Johansson, B S; Lindberg, L G; Svensson, M L


    The Peterson and Peterson (1959) STM experiment was replicated with variation of presentation modality and encoding strategy. The effect of various scoring criteria was also analyzed. The recall data showed that a Peterson and Peterson type forgetting curve was obtained using auditory presentation and instructions to rehearse vocally the trigrams when scoring only completely correct recall within the first 3 sec of the recall interval. With visual presentation and instructions to find meaningful trigram interpretations, the forgetting curve was higher and much more flat, especially when scoring position correct recall within the total 0-10-sec recall interval. In a buildup of PI experiment, no buildup of PI could be detected when visual presentation was used together with instructions to find meaningful trigram interpretations. The importance of the different encoding activities for recall performance was discussed.

  11. Methylenation of perfluoroalkyl ketones using a Peterson olefination approach. (United States)

    Hamlin, Trevor A; Kelly, Christopher B; Cywar, Robin M; Leadbeater, Nicholas E


    An operationally simple, inexpensive, and rapid route for the olefination of a wide array of trifluoromethyl ketones to yield 3,3,3-trifluoromethylpropenes is reported. Using a Peterson olefination approach, the reaction gives good to excellent yields of the alkene products and can be performed without purification of the β-hydroxysilyl intermediate. The reaction can be extended to other perfluoroalkyl substituents and is easily scaled up. The alkenes prepared can be readily transformed into a variety of other perfluoroalkyl-containing compounds.

  12. Alpha brain wave production as an interpolated task in a Brown-Peterson paradigm. (United States)

    Bridges, C C; Rollings, H E


    Rehearsal, backward counting, and production of alpha brain-waves were used as interpolated tasks in a Brown-Peterson paradigm to determine their effect upon verbal retention. A within-subjects design was used in which trained subjects were told on a given trial either to produce alpha rhythm, mentally rehearse, or count backward following presentation of a CCC trigram. Results for the backward-counting condition duplicate, for the retention intervals used, the shape of the classic Peterson and Peterson forgetting curve but indicate little loss of memory in either the rehearsal or alpha conditions. No siginificant difference was found between the alpha production and rehearsal conditions.

Armstrong and Walker also both flew the X-15. Soon after this photo was taken, Armstrong was selected as an astronaut, and seven years later became the first man to walk on the Moon. Walker made the highest flight in the X-15, reaching 354,200 feet. He then went on to fly the Lunar Landing Research Vehicle, and was killed on June 8, 1966 when his F-104N collided with the XB-70. Peterson made the first flight in the HL-10 lifting body, and was later badly injured in the crash of the M2-F2 lifting body. Butchart flew a wide range of research missions in the 1950s, and was the B-29 drop plane pilot for a number of rocket flight.

  19. The Vioxx pharmaceutical scandal: Peterson v Merke Sharpe & Dohme (Aust) Pty Ltd (2010) 184 FCR 1. (United States)

    Faunce, Thomas; Townsend, Ruth; McEwan, Alexandra


    In early March 2010, Federal Court Justice Jessup in Peterson v Merke Sharpe & Dohme (Aust) Pty Ltd (2010) 184 FCR 1 ruled that Merke Sharpe & Dohme Pty Ltd had produced a defective product contrary to the Trade Practices Act 1974 (Cth), the anti-arthritic drug Vioxx. Promoted as relieving arthritic pain without the side effect of gastric ulceration, the drug also doubled the risk of heart attack in those prescribed it. The court also heard that the manufacturing company had engaged in misleading practices to promote the prescription and usage of Vioxx, including "fake" journals and guidelines to "drug reps" that minimised the adverse cardiovascular risks. The manufacturer had already settled a class action in the United States for more than US$7 billion for those harmed by the drug but this was the first such case to be decided in Australia. The court awarded the applicant, Graeme Peterson, A$300,000 in damages. This column examines this judgment and analyses evidence there presented that Merck may have misled the scientific community, the medical profession and Australia's drug regulation system to get Vioxx on the market and keep it there. It considers whether the case reveals the need for more rigorous post-marketing surveillance and other changes to Australia's drug regulatory system, including a replacement of self-regulation in pharmaceutical promotion with a United States-style system of rewarded informant-led criminal penalties and civil damages claims.

  20. Isolable 2,3-disila-1,3-butadiene from a double sila-Peterson reaction. (United States)

    Motomatsu, Daiki; Ishida, Shintaro; Ohno, Koichi; Iwamoto, Takeaki


    A new 2,3-disila-1,3-butadiene (3) was synthesized as pale yellow crystals by a double sila-Peterson reaction of 1,1,2,2-tetrasilyl-1,2-dilithiodisilane with two equivalents of 2-adamantanone at 0 °C. In the solid state, the two Si=C bonds adopt a synclinal conformation with a dihedral angle of 76.8(1)°. UV/Vis spectra show two distinct absorption bands, assignable to the π(Si=C)→π*(Si=C) transition, at 371 and 322 nm and the former is considerably redshifted compared with that of structurally similar silenes. The 2,3-disilabutadiene isomerizes to the corresponding 1,3-disilabicyclo[1.1.0]butane with the activation parameters of ΔH(≠) = 74.5±5.4 kJ mol(-1) and ΔS(≠) = -71.1±17.1 J mol(-1)  K(-1). DFT studies suggest that the isomerization proceeds through a conrotatory route rather than a disrotatory route. H2O and 9,10-phenanthrenequinone added across each Si=C bond in the 2,3-disila-1,3-butadiene. The UV/Vis spectrum and reactivity of 3 suggest that the interaction between the two Si=C bonds in 3 would be significant but rather small compared with that between Si=Si bonds in a synclinal tetrasilabutadiene. © 2014 WILEY-VCH Verlag GmbH & Co.

  2. Normative data for a computer-assisted version of the auditory three-consonant Brown-Peterson paradigm in the elderly French-Quebec population. (United States)

    Callahan, Brandy L; Belleville, Sylvie; Ferland, Guylaine; Potvin, Olivier; Tremblay, Marie-Pier; Hudon, Carol; Macoir, Joël


    The Brown-Peterson task is used to assess verbal short-term memory as well as divided attention. In its auditory three-consonant version, trigrams are presented to participants who must recall the items in correct order after variable delays, during which an interference task is performed. The present study aimed to establish normative data for this test in the elderly French-Quebec population based on cross-sectional data from a retrospective, multi-center convenience sample. A total of 595 elderly native French-speakers from the province of Quebec performed the Memoria version of the auditory three-consonant Brown-Peterson test. For both series and item-by-item scoring methods, age, education, and, in most cases, recall after a 0-second interval were found to be significantly associated with recall performance after 10-second, 20-second, and 30-second interference intervals. Based on regression model results, equations to calculate Z scores are presented for the 10-second, 20-second and 30-second intervals and for each scoring method to allow estimation of expected performance based on participants' individual characteristics. As an important ceiling effect was observed at the 0-second interval, norms for this interference interval are presented in percentiles.

  7. Additional sagittal correction can be obtained when using an expandable titanium interbody device in lumbar Smith-Peterson osteotomies: a biomechanical study. (United States)

    Qandah, Nicholas A; Klocke, Noelle F; Synkowski, Jordan J; Chinthakunta, Suresh R; Hussain, Mir M; Salloum, Kanaan G; Marvin, Eric A; Bucklen, Brandon S


    Insertion of intervertebral fusion devices between consecutive Smith-Peterson osteotomies (SPOs) provides an anterior fulcrum during compression, which has been documented to improve achievable Cobb angle correction. Extension of these principles to an expandable device would theoretically provide greater surgical adjustment for flatback and scoliotic cases than a static cage. To investigate whether an expandable titanium interbody device would produce greater sagittal correction than a static spacer when used during SPO procedures. Cadaveric research was performed. Seven T10-S1 human specimens were used. Cobb angle changes and range of motion are the physiological measures. No self-report/functional measures were applicable. Bilateral pedicle screws were placed (T11-L5) before Smith-Petersen osteotomy creation from L2 to L4. A transforaminal lumbar interbody fusion titanium expandable implant was placed in each disc space from L2-L3 to L4-L5, which is currently an off-label use of this implant. Initial placement simulated a static spacer, and then incremental device expansion was performed to obtain an intermediate and final height. Lateral fluoroscopic images were taken for Cobb angle evaluation between L2 and L5, and range of motion as observed during application of pure bending moments was captured using a six degree-of-freedom spine simulator. A one-way analysis of variance with Tukey post hoc analysis was performed to determine significant differences (pcompany, where some authors are salaried employees; another author has been a paid consultant elsewhere. These financial associations were not believed to bias the results. Change in Cobb angle from L2 to L5 was significantly greater with the interbody spacer compared with SPO alone. Despite an obvious increase in lordosis with expansion height, there were no significant differences between implant expansion states for the L2-L5 Cobb angle. All instrumented constructs were statistically equivalent in every

Üllatav on autori jaoks ka Euroopa Liidu nõue, et põhimõttelised küsimused - Küprose tunnustamine ja Armeenia genotsiidi omaksvõtmine - peab Türgi lahendama alles liitumisläbirääkimiste lõpuks.

  19. A new treatment of focusing by varied-line-spacing gratings with application to the Peterson PGM system

    International Nuclear Information System (INIS)

    Howells, M.R.; Staub, U.


    We present a new treatment for a varied-line-spacing grating (VLS) as a monochromator for a soft X-ray synchrotron beamline. Our calculations for a VLS monochromator show that within the small angle approximation we can make the focal length constant, correct for primary coma and spherical aberrations at all wave lengths. This monochromator scheme has still a free choice of included angle, which can be used to optimize efficiency and it can cover a wave length range of eight octaves, distinct more compared to a plane grating monochromator scheme. The analytical calculations are in excellent agreement with our ray traces using the Shadow computer code. (author) 7 figs., tabs., 27 refs

  2. Review: Robert V. Kemper & Anya Peterson Royce (Eds. (2002. Chronicling Cultures: Long-term Field Research in Anthropology

    Directory of Open Access Journals (Sweden)

    Maximilian C. Forte


    Full Text Available Chronicling Cultures provides readers with detailed case histories of ethnographic projects that are long-term in duration, lasting decades in some cases and often involving multiple collaborators and new generations of researchers. The central theme of the text is that extended time spent in the field leads to both qualitative and quantitative transformations in research. Contributors to the volume examine these transform­ations with respect to the data gathering process, the theoretical outcomes of long-term research, the impacts on host communities and the many problems and benefits of spending extended time in the field through multiple revisits and restudies. The volume will be of especial interest to those interested in the history of anthropology and to a lesser degree those interested in field methods. Amongst the shortcomings of the volume are its somewhat loose thematic organization, the overly descriptive nature of many of the contributions, the narrow range of cases selected and the lack of diverse perspectives.

  3. Moment Tensor code for the Antelope Environmental Monitoring System (United States)

    Reyes, J.; Newman, R.; Vernon, F.; van den Hazel, G.


    The time domain seismic moment tensor inversion software package written by Dreger (2003) and updated by Minson & Dreger (2008) has been rewritten for inclusion into the open-source contributed code repository for the Boulder Real Time Technology (BRTT) Antelope Environmental Monitoring System. The new code-base was written natively in the Python language and utilizes the Python interface to Antelope (Lindquist et al., 2008) for data access, Scientific Tools for Python library (Eric Jones et al., 2001) for computation and analysis, and the ObsPy library (Beyreuther et al., 2010) for graphical representation. The new code archives all data products into a Center for Seismic Studies (CSS) 3.0 schema table for easy access and distribution of solutions. Stability of the analysis, verification of results and correlation of solutions with similar methods are discussed in this presentation. Analysis is focused on regional earthquakes recorded by Earthscope's USArray network and event parameters are taken from real time and post-event processed data analysis at the Array Network Facility (ANF). A calibrated velocity model representative of the south-west continental United States is used for the analysis. Beyreuther, M., Barsch, R., Krischer, L., Megies, T., Behr, Y. and Wassermann, J.

    Dodelson, Scott; Jubas, Jay M.


    Gunn-Peterson tests suggest that the Universe was reionized after the standard recombination epoch. A systematic treatment is presented of the ionization process by deriving the Boltzmann equations appropriate to this regime. A compact solution for the photon spectrum is found in terms of the ionization ratio. These equations are then solved numerically for the Decaying Dark Matter scenario, wherein neutrinos with mass of order 30 eV radiatively decay producing photons which ionize the intergalactic medium. It was found that the neutrino mass and lifetime are severely constrained by Gunn-Peterson tests, observations of the diffuse photon spectrum in the ultraviolet regime, and the Hubble parameter.

  2. Isotherm investigation for the sorption of fluoride onto Bio-F: comparison of linear and non-linear regression method (United States)

    Yadav, Manish; Singh, Nitin Kumar


    A comparison of the linear and non-linear regression method in selecting the optimum isotherm among three most commonly used adsorption isotherms (Langmuir, Freundlich, and Redlich-Peterson) was made to the experimental data of fluoride (F) sorption onto Bio-F at a solution temperature of 30 ± 1 °C. The coefficient of correlation (r2) was used to select the best theoretical isotherm among the investigated ones. A total of four Langmuir linear equations were discussed and out of which linear form of most popular Langmuir-1 and Langmuir-2 showed the higher coefficient of determination (0.976 and 0.989) as compared to other Langmuir linear equations. Freundlich and Redlich-Peterson isotherms showed a better fit to the experimental data in linear least-square method, while in non-linear method Redlich-Peterson isotherm equations showed the best fit to the tested data set. The present study showed that the non-linear method could be a better way to obtain the isotherm parameters and represent the most suitable isotherm. Redlich-Peterson isotherm was found to be the best representative (r2 = 0.999) for this sorption system. It is also observed that the values of β are not close to unity, which means the isotherms are approaching the Freundlich but not the Langmuir isotherm.

  11. Memory in myasthenia gravis: neuropsychological tests of central cholinergic function before and after effective immunologic treatment. (United States)

    Glennerster, A; Palace, J; Warburton, D; Oxbury, S; Newsom-Davis, J


    There are reports of central cholinergic deficits in myasthenia gravis (MG) describing impaired performance on a variety of tests of memory with varying benefits from plasmapheresis. We tested 11 patients with symptomatic MG at the start of a trial of immunosuppressive treatment (prednisolone plus azathioprine or placebo) and again when in remission. The tests included the Logical Memory and Design Reproduction parts of the Wechsler Memory Scale, the Rey Auditory Verbal Learning Test, Peterson-Peterson task, and an auditory vigilance task. Muscle strength improved significantly over the period of treatment, but overall performance on tests of memory or attention did not. These results fail to substantiate reports of functionally significant and reversible central deficits in myasthenia gravis.


    Directory of Open Access Journals (Sweden)

    Edward Nicodemus Lontah


    Donaldson and Peterson studies have shown that stakeholder theory has a more solid foundation than the epistemology of shareholder theory to analyze the performance of business ethics and moral duty of a company. This article discussed the business activities of Oskar Schindler, an industrialist war-profiteer during World War II. Schindler's business which was originally run by the government under the Nazi regime, eventually opposed the mission of economic and legal liability imposed by the regime. Schindler's transformation of vision and business mission in this article demonstrate the characteristics and connection of layers in descriptive, instrumental and normative stakeholder theory in the concept of "normative, instrumental and descriptive stakeholder theory" according to Donaldson and Peterson.

    Chapman, Lauren Elizabeth


    Mental health is an important part of college studentsâ experiences, and more administrators are paying attention to mental health issues (Cooper, 2000; Kitzrow, 2003). Self-esteem is central to mental health (Kittleson, 1989), and can be attributed to social situations, especially those that deal with rejection (Bednar, Wells, & Peterson, 1989; Caunt, 2003; Eisenberger & Lieberman, 2004; Steffenhagen & Burns, 1987). Sorority recruitment is an event that includes rejection (National Panhell...

  4. Failure to Fail in a Final Pre-service Teaching Practicum


    Patricia J. Danyluk; Florence Luhanga; Yovita N. Gwekwerere


    This article presents a Canadian perspective on the issue of failure to fail in Bachelor of Education programs. The issue of failure to fail in Bachelor of Education programs is one that had not been explored in any great detail. What literature does exist focuses on the strain that a teacher experiences when s/he mentors a student teacher (Siebert, Clark, Kilbridge, & Peterson, 2006) and the wide variety of situations that can result in failure (Sudzina & Knowles, 1992). This study examines ...

  11. Predicting Reading Comprehension of 8th grade Struggling Readers: Fluency, Self-Efficacy, and Intrinsic Motivation


    Liao, Christy


    Several theories contribute to explaining factors that influence text comprehension in struggling readers. Some authors assume a simple view in which fluent word recognition and adequate language comprehension leads to comprehension of text (Gough, Hoover, & Peterson, 1996). A broad base of research evidence supports the substantial impact of reading fluency in students’ reading comprehension in elementary grades (Fuchs, Fuchs, Hosp, & Jenkins, 2001). However, as students move from elementary...

  17. Risk and uncertainty assessment of volcanic hazards


    Sparks, R S J; Aspinall, Willy P; Crosweller, H S; Hincks, Thea K


    Introduction: Over 600 million people live close enough to active volcanoes to have their lives disrupted if there are signs of unrest that might lead to eruption, and threatened when an eruption does occur. This estimate is an update of the analysis of Tilling and Peterson (1993) and Small and Naumann (2001) using 2009 World Bank population data. In comparison to other natural hazards, such as earthquakes and floods, the historic death toll from volcanoes is quite small. Since about 1500 CE ...

  4. New comprehensive standard seismic noise models and 3D seismic noise variation for Morocco territory, North Africa, obtained using seismic broadband stations (United States)

    El Fellah, Younes; El-Aal, Abd El-Aziz Khairy Abd; Harnafi, Mimoun; Villaseñor, Antonio


    In the current work, we constructed new comprehensive standard seismic noise models and 3D temporal-spatial seismic noise level cubes for Morocco in north-west Africa to be used for seismological and engineering purposes. Indeed, the original global standard seismic noise models published by Peterson (1993) and their following updates by Astiz and Creager (1995), Ekström (2001) and Berger et al. (2003) had no contributing seismic stations deployed in North Africa. Consequently, this preliminary study was conducted to shed light on seismic noise levels specific to north-west Africa. For this purpose, 23 broadband seismic stations recently installed in different structural domains throughout Morocco are used to study the nature and characteristics of seismic noise and to create seismic noise models for Morocco. Continuous data recorded during 2009, 2010 and 2011 were processed and analysed to construct these new noise models and 3D noise levels from all stations. We compared the Peterson new high-noise model (NHNM) and low-noise model (NLNM) with the Moroccan high-noise model (MHNM) and low-noise model (MLNM). These new noise models are comparable to the United States Geological Survey (USGS) models in the short period band; however, in the period range 1.2 s to 1000 s for MLNM and 10 s to 1000 s for MHNM display significant variations. This variation is attributed to differences in the nature of seismic noise sources that dominate Morocco in these period bands. The results of this study have a new perception about permanent seismic noise models for this spectacular region and can be considered a significant contribution because it supplements the Peterson models and can also be used to site future permanent seismic stations in Morocco.

  5. Galeazzi - Equivalent Pronation Type Injury with Splitting of Ulnar Epiphyseal Plate into Two Fragments - A Rare Case Report and Review of Literature. (United States)

    J, Ashish Suthar; V, Ashish Kothari


    In children and adolescents distal forearm physeal fractures are common. Usually distal forearm physeal injuries of are common injuries in children and adolescents. Epiphyseal injuries to the distal radius are common in children, but involvement of the distal ulna is rare. Fracture of the distal radius with dislocation of the DRUJ is known as a True Galeazzi fracture dislocation and an epiphyseal separation of the distal ulna occurred instead of dislocation of DRUJ or both)[10] is called Galeazzi equivalent lesions. Galeazzi fractures in children are less common than in adults. [4] These injuries are uncommon and there are few descriptions of them in the current literature. Here we report the case of a 13-year-old boy, student with history of RTA presented with pain and swelling of distal forearm diagnosed with closed injury of Galeazzi equivalent type. Here injury to the distal ulnar epiphyseal plate is in the form of epiphyseal separation (Salter Harris type I / Peterson type III) with splitting of epiphysis into two fragment - [ulnar styloid & radial side of ulnar epiphyseal plate] (Salter Harris type III / Peterson type IV) with fracture of metaphysis of lower end radius (Peterson type I) without neurovascular deficit. Patient was given surgical treatment in the form of closed reduction and K-wire fixation for fracture of distal radius and open reduction using extended ulnar approach and fixation with K-wire for ulnar epiphyseal fracture as closed reduction was not possible due to soft tissue interposition. Galeazzi equivalent injury is rare. It may require radiographic comparison of opposite uninvolved distal forearm with wrist, CT or MR imaging to define injury accurately. It may also require open reduction for anatomical or acceptable reduction of fracture to minimize chances of growth arrest which may occur as a complication of injury. It is also necessary for frequent follow up to identify complication early especially growth arrest in asymptomatic patient.

  6. Ambient seismic noise levels: A survey of the permanent and temporary seismographic networks in Morocco, North Africa (United States)

    El Fellah, Y.; Khairy Abd Ed-Aal, A.; El Moudnib, L.; Mimoun, H.; Villasenor, A.; Gallart, J.; Thomas, C.; Elouai, D.; Mimoun, C.; Himmi, M.


    Abstract The results, of a conducted study carried out to analyze variations in ambient seismic noise levels at sites of the installed broadband stations in Morocco, North Africa, are obtained. The permanent and the temporary seismic stations installed in Morocco of the Scientific Institute ( IS, Rabat, Morocco), institute de Ciencias de la Tierra Jaume almera (ICTJA, Barcelona, Spain) and Institut für Geophysik (Munster, Germany) were used in this study. In this work, we used 23 broadband seismic stations installed in different structural domains covering all Morocco from south to north. The main purposes of the current study are: 1) to present a catalog of seismic background noise spectra for Morocco obtained from recently installed broadband stations, 2) to assess the effects of experimental temporary seismic vault construction, 3) to determine the time needed for noise at sites to stabilize, 4) to establish characteristics and origin of seismic noise at those sites. We calculated power spectral densities of background noise for each component of each broadband seismometer deployed in the different investigated sites and then compared them with the high-noise model and low-noise Model of Peterson (1993). All segments from day and night local time windows were included in the calculation without parsing out earthquakes. The obtained results of the current study could be used forthcoming to evaluate permanent station quality. Moreover, this study could be considered as a first step to develop new seismic noise models in North Africa not included in Peterson (1993).

  17. Gluon fragmentation in T(1S) decays

    International Nuclear Information System (INIS)

    Bienlein, J.K.


    In T(1S) decays most observables (sphericity, charged multiplicity, photonic energy fraction, inclusive spectra) can be understood assuming that gluons fragment like quarks. New results from LENA use the (axis-independent) Fox-Wolfram moments for the photonic energy deposition. Continuum reactions show 'standard' Field-Feynman fragmentation. T(1S) decays show a significant difference in the photonic energy topology. It is more isotropic than with the Field-Feynman fragmentation scheme. Gluon fragmentation into isoscalar mesons (a la Peterson and Walsh) is excluded. But if one forces the leading particle to be isoscalar, one gets good agreement with the data. (orig.)

    In our recent article ("Production of Mesons by X-Rays," by Edwin M. McMillan, Jack M. Peterson, and R.

When a negative pi(-)meson is made by a photon striking a neutron, the products are pi(-) and p(+), not pi(-) and pi(+). Also, near the center of page 580, in the third paragraph "pi=mesons" was incorrectly printed for "pi(-)mesons."

    Natural zeolite was used for the removal of malachite green (MG) from aqueous solution in batch mode and reused by microwave irradiation. The isotherm data were analyzed by the Langmuir, Freundlich, Redlich-Peterson, and Koble-Corrigan isotherm model. The better fit for the equilibrium process was Koble-Corrigan model. The kinetic studies indicated that the adsorption followed the pseudo-second-order kinetic. Thermodynamic calculations showed that the adsorption was spontaneous and endothermic process. Spent zeolite was treated by microwave irradiation and it was found that yield of regeneration was 85.8% in the case of microwave irradiated time 10 min at 160 W.

  4. Automorphism modular invariants of current algebras

    International Nuclear Information System (INIS)

    Gannon, T.; Walton, M.A.


    We consider those two-dimensional rational conformal field theories (RCFTs) whose chiral algebras, when maximally extended, are isomorphic to the current algebra formed from some untwisted affine Lie algebra at fixed level. In this case the partition function is specified by an automorphism of the fusion ring and corresponding symmetry of the Kac-Peterson modular matrices. We classify all such partition functions when the underlying finite-dimensional Lie algebra is simple. This gives all possible spectra for this class of RCFTs. While accomplishing this, we also find the primary fields with second smallest quantum dimension. (orig.). With 3 tabs

  5. Creativity in biological research. (United States)

    Maas, Werner


    During the past century, several biologists have studied the mental processes involved in creativity. In recent years psychologists have approached the subject experimentally. In one such study (Carson, Peterson, and Higgins 2003), creativity has been shown to originate in the subconscious mind and to be transmitted to the conscious mind as a result of a decrease in latent inhibition, an ordinarily strong cognitive barrier between the conscious mind and the subconscious. In my scientific work I have found evidence for creativity in the design of experiments, in which the addition of apparently superfluous controls has led to important discoveries.

    We present new sets of nonperturbative fragmentation functions for D^0, D^+, and D_s^+ mesons as well as for Lambda_c^+ baryons, both at leading and next-to-leading order in the MSbar factorization scheme with five massless quark flavors. They are determined by fitting data of e^+e^- annihilation taken by the OPAL Collaboration at CERN LEP1. We take the charm-quark fragmentation function to be of the form proposed by Peterson et al. and thus obtain new values of the epsilon_c parameter, which are specific for our choice of factorization scheme.

    peasants’ use of dialect speech. This is not intended to judge peasant language as inferior, but to represent the social reality of the time truthfully. Tammsaare’s personal views indicate that he considered the expressive possibilities of dialect to be less extensive than that of written language. However, since the characters’ speech serves the purpose of verisimilitude, it is perhaps more accurate to say that the novel represents natural use of language. In this context, Tammsaare leaves space in his representation of social reality for satire and mockery of those characters who aspire to be like the Germans, and makes fun of their language use. The characters’ speech in dialect supports many of the pervasive motifs in the novel. One of the main goals is to differentiate the two farmowners at Vargamäe, Oru Pearu and Mäe Andres and build an opposition between them. The linguistic opposition is expressed by the diphthongisation of the long, low vowels (characteristic of the central Estonian dialect, as in the speech of Pearu and his wife, while this element is absent from the direct speech of Andres’ family. The fact that the writer used this feature primarily to construct an opposition between main characters is further supported by the speech of other inhabitants of the area, in which the diphthongized forms should have been predominant. The nuancing feature of dialect was introduced into the novel in the interest of strengthening its sense of realism; sketching the outlines of characters, their surroundings, and ideational structures attests to the author’s skill in using formal features, and confirms that the writer submitted the dialect speech of the characters to firm creative purposes. Similarly, the analysis of the speech of characters as a fragment of structure allows us to conjecture about how consciously Tammsaare represented the different layers of form in Truth and Justice Part I.

    Zanella Odivan


    Full Text Available In this study, nitrate (NO3- removal from aqueous solutions was investigated using granular activated carbon (GAC modified with CaCl2. Batch sorption studies were performed as a function of sorbent dose, initial nitrate concentration and pH. Sorption was maximized between pH 3 and 9. Studies on the effect of pH showed that the ion exchange mechanism might be involved in the sorption process. The percentage of nitrate removed increased with increasing sorbent concentration, and the ideal sorbent dose was found to be 20 g•L-1. Four isotherm models-Langmuir, Freundlich, Redlich-Peterson and Sips-were used to fit the experimental data. The Redlich-Peterson isotherm model explained the sorption process well and showed the best coefficient of determination (0.9979 and Chi-square test statistic (0.0079. Using the Sips isotherm model, the sorption capacity (qe was found to be 1.93 mg nitrate per g of sorbent. Kinetic experiments indicated that sorption was a fast process, reaching equilibrium within 120 min. The nitrate sorption kinetic data were successfully fitted to a pseudo-second-order kinetic model. The overall results demonstrated potential applications of modified GAC for nitrate removal from aqueous solutions.

  3. Utilisation of Agriculture Weed for the Removal of Cr(VI) from Aqueous Solution. (United States)

    Natarajan, Balasubramanian; Nagarajan, Sulochana


    The present study investigates the potential use of activated carbon prepared from Cassia tora by sulphuric acid treatment for the removal of Chromium(VI) from aqueous solution. The effects of pH, initial concentration, contact time, and carbon concentration were studied for the sorption of Cr(VI) in batch mode. The optimum pH value for Cr(VI) adsorption was determined as 2.0. The experimental results were fitted with the Freundlich, Langmuir and Redlich Peterson equations to describe the equilibrium isotherms. The Langmuir and Redlich - Peterson isotherm models were found better to describe the experimental data. The maximum adsorption capacity obtained from Langmuir equation was 72.4 mg/g. The kinetic data were then fitted with the Lagergren-first-order, pseudo-second-order and intraparticle models. Further, adsorption kinetics of Cr(VI) was studied and the rate of adsorption was found to confirm pseudo-second-order kinetics with a good correlation and intraparticle diffusion as one of the rate determining steps. Activated carbon developed from Cassia tora can be a potential alternative for Cr(VI) removal from aqueous solution.

  4. Application of two-parameter and three-parameter isotherm models at uranium bio sorption by baker's yeast

    Keshtkar, A.; Montazer Rahmati, M. M.; Khodapanah, N.


    In this work, the ability of free and immobilized deactivated baker's yeast saccharomyces cerevisiae to remove uranium ions was investigated using a batch bio sorption procedure with respect to the initial p H (3.0-6.0), contact time (24 h), initial ion concentration (50-400 mg/g) and presence of secondary ions (Cr(V I)). The removal of uranium was approximately 90% and 50% at low concentrations, whereas it was about 80% and 15% at high concentrations at an optimum p H of 5 and 5.5, using 1 g/1 of adsorbent in 24 h of equilibration time for immobilized and free baker's yeast, respectively. Experimental results at 30 d eg C indicated that the uptake capacity of uranium ions by immobilized baker's yeast biomass on calcium alginate was reduced by the presence of secondary ions. The experimental data obtained at the optimum have been analyzed using two two-parameter models, Langmuir and Freundlich, and one three-parameter model, Redlich-Peterson. Taking into three statistical error functions, the data were best fitted to the Redlich-Peterson model. Using the Langmuir equation, the saturated monolayer sorption capacities of uranium ions onto immobilized and free baker's yeast were 592.8 and 73 mg/g, respectively at 30 d eg C .

    Full Text Available Grit is explaining in Dictionary of the Turkish language Association as determination and desire to have identified the level of long-term goals. Duckworth, Peterson, Matthews, and Kelly (2007 are definiting it as, perseverance and passion for Long-Term Goals. In addition to stating that grit is an important factor in measuring the intelligence and the success. At the same time they have stressed that the grit is much more important predictors of success. Even Duckworth and Quinn (2009 argued that grit is more effective than intelligence scores for explainig the success. There are some studies that they are advocating grit is closely associated with self-discipline, self-regulation and goal orientation, and grit is the main factor for exlaining that concpts(Duckworth & Quinn, 2009; Peterson & Seligman, 2004. In this study, university student success and their grit's are analysed. Therefore, determining the relationship between success and grit is used for descriptive screening model. This study was conducted with 451 students in Education Faculty at Necmettin Erbakan University in 2015-2016 academic year spring semester. In order to data collecting "Grit-S scale", developed by Duckworth and Quinn (2009 and adapted to Turkish by Sarıcam and others (2015, was used. Datum were analysed by SPSS 16 soft ware and frequency, mean, standard deviation and regresion test were used as statistical techniques. The achievement scores of students have found a significant correlation between the grit scores.

    Full Text Available Dianzhong Luo, Hong Zhang, Weijia Zhang Division of Joint Surgery and Sport Medicine, Department of Orthopaedics, First Affiliated Hospital of Chinese PLA General Hospital, Beijing, People’s Republic of China Background: Developmental dysplasia of the hip is a common disease and treated with various surgical approaches. Improved ilioinguinal (I-I approach, two-incision Smith-Peterson (TSP approach, and modified Smith-Peterson (MSP approach are three main approaches; however, they are rarely compared. The present study compared the operative time, blood loss, intraoperative and postoperative allogeneic blood transfusion, and postoperative complications of these three different approaches. Hypothesis: Surgical approach does not influence the operation time, blood loss, and complications of periacetabular osteotomy. Level of evidence: Level III. Case–control study. Patients and methods: In a total of 101 hips of 95 cases, from February 2010 to July 2011, three different approaches of Bernese periacetabular osteotomy, I-I, TSP, and MSP, were conducted. The operation time, intraoperative bleeding, allogeneic blood transfusion, and early complications in different operation approaches were compared by a retrospective study when there were similar ages, genders, and lesions. Results: Among the three approaches, I-I had less operation time and more blood loss (P<0.05, TSP had less blood loss (P<0.05 but more complications, and MSP had less blood loss (P<0.05 and less complications. Discussion: The MSP approach is superior to the other two approaches in doing periacetabular osteotomy. Keywords: periacetabular osteotomy, operation approaches, complications

  7. Mechanical properties of the aortic arterial wall during 24 hours: a preliminary study in conscious sheep (United States)

    Graf, S.; Craiem, D.; Valero, M.; Alfonso, M.; Barra, J. G.; Armentano, R. L.


    Previous experiences in animals showed a different behavior between the variability of pressure, arterial diameter and elasticity when they were registered for a couple of hours. To better understand arterial mechanics variability, we propose to measure simultaneously aortic pressure and diameter during 24 hours in a sheep. For that purpose, we developed a portable prototype device. It allows continuously recording physiological signals throughout the day and storing them in a solid state memory for later analysis. Pulse wave velocity and Peterson modulus were assessed beat-to-beat as arterial stiffness indexes. We identified 53,762 heart beats during 24 hours that were separated into 2 groups: below or above median mean pressure (71 mmHg). Mean diameter, pulse wave velocity and Peterson modulus increased for higher pressure values (p<0.05) whereas heart rate slowed down (p<0.05). Pressure-diameter loops were successfully recreated all along the experience. This new methodology sets the basis for further experiences involving the estimation of 24 hours arterial mechanics variability.

  8. High-cycle notch sensitivity of alloy steel ASTM A743 CA6NM used in hydrogenator turbine components

    Directory of Open Access Journals (Sweden)

    José Alexander Araújo


    Full Text Available The presence of notches and other stress concentrations in turbine blades and other notch hydraulic components is a current problem in engineering. It causes a reduction of endurance limit of material. In that sense, specimens of the ASTM A743 CA6NM alloy steel using in several hydrogenator turbine components was tested. The specimens were tested under uniaxial fatigue loading with a load ratio equal to -1, and the considered stress concentration factors, Kt, values, calculated with respect to net area, were 1.55, 2.04 and 2.42. In order to determine the fatigue limit for such notch type, a reduction data method by Dixon and Mood, Staircase method was used. This approach is based on the assumed target distribution of the fatigue limit. For such geometry at least 8 specimens were tested. In addition, the Peterson and Neuber’s notch fatigue factor were compared through fatigue notch reduction factor, Kf, obtained from experimental data. According to results obtained it was possible to conclude that the tested material is less sensitive to notches than the prediction of the Peterson and Neuber’s empirical models.

    Bilgili, M. Sinan


    Removal of 4-chlorophenol (4-CP) from synthetic aqueous solutions through adsorption on Amberlite XAD-4 resin, a non-ionic macroreticular resins, under batch equilibrium experimental conditions at 298, 308 and 318 K was investigated. It is necessary to propose a suitable model to a better understanding on the mechanism of 4-CP adsorption. For this purpose, Langmiur, Freundlich, Toth, and Redlich-Peterson (RP) isotherm models were compared. The two and three parameters in the adopted adsorption isotherm models were determined by the help of MATLAB package program. It was determined that best fitted adsorption isotherm models were obtained to be in the order: Redlich-Peterson > Langmuir > Toth > Freundlich isotherms. The pseudo-second-order kinetic model provided the best correlation to the experimental results. Results of the intra-particle diffusion model show that the pore diffusion is not the only rate limiting step. The lower correlation of the data to the Bangham's equation also represents that the diffusion of the adsorbate into pores of the sorbent is not the only rate-controlling step. The thermodynamic constants of adsorption phenomena; ΔG o , ΔH o , and ΔS o were found as -4.17 (at 298 K) kJ/mol, -42.01 kJ/mol, and -0.127 kJ/(mol K), respectively. The results showed that adsorption of 4-CP on Amberlite XAD-4, a nonionic polymeric resin was exothermic and spontaneous

    Full Text Available Contamination of the aqueous environment by heavy metals is a worldwide environmental problem. Biosorption of lead (II and cadmium (II from aqueous solutions by brown algae Sargassum spp.biomass was studied in a batch system. The heavy metals uptake was found to be rapid and reached to 88-96% of equilibrium capacity of biosorption in 15min. The pseudo second-order and saturation rate equations were found in the best fitness with the kinetic data (R2 > 0.99. The data obtained from experiments of single-component biosorption isotherm were analyzed using the Freundlich, Langmuir, Freundlich-Langmuir and Redlich-Peterson isotherm models. The Redlich-Peterson equation described the biosorption isotherm of Pb2+ and Cd2+ with high correlation coefficient (R2 > 0.99 and better than the other equations. The effect of Na+, K+, Mg2+ and Ca2+ on the biosorption of Pb2+ was not significant, but the metal ions affected the biosorption of Cd2+ considerably. According to the Langmuir model, the maximum uptake capacities (qm of Sargassum spp. for Pb2+ and Cd2+ were obtained as 1.70 and 1.02mmol/g, respectively. Although the Sargassum spp. used in this study can be classified as an efficient biosorbent.

    Full Text Available A series of poly(2-hydroxyethyl acrylate-co-itaconic acid, P(HEA/IA, hydrogels with different HEA/IA ratio, were synthesized using free radical crosslinking/copolymerization and investigated as sorbents for Pb2+ ions from aqueous solutions. Hydrogels were characterized using DMA, FTIR, DSC, SEM and AFM. The adsorption was found to be highly dependent on hydrogel composition, solution pH, sorbent weight, ionic strength and contact time. Five isotherm models, Langmuir, Freundlich, Redlich-Peterson, Temkin and Dubinin-Radushkevich, were applied to the sorption data. The best fit was obtained with Redlich-Peterson isotherm. The separation factor, RL, value indicated favorable sorption for Pb2+ ions. The maximum sorption capacities were 392.2 and 409.8 mg/g for P(HEA/2IA and P(HEA/10IA, respectively. Kinetic data showed best fit with pseudo-second-order model. Thermodynamic studies revealed that the reaction was exothermic and proceeds with a decrease in entropy. Moreover, P(HEA/IA hydrogel showed the most pronounced sorption toward Pb2+ ions from environment containing Cu2+, Zn2+, Cd2+, Ni2+ and Co2+ ions. Sorption/desorption experiments, showed that the P(HEA/IA hydrogels could be reused without significant loss of the initial properties even after three adsorption-desorption cycles.

  13. Structural Complexity Through Multicomponent Cycloaddition Cascades Enabled by Dual-Purpose, Reactivity Regenerating 1,2,3-Triene Equivalents (United States)

    Wender, Paul A.; Fournogerakis, Dennis N.; Jeffreys, Matthew S.; Quiroz, Ryan V.; Inagaki, Fuyuhiko; Pfaffenbach, Magnus


    Multicomponent reactions allow for more bond-forming events per synthetic operation, enabling more step and time economical conversion of simple starting materials to complex and thus value-added targets. These processes invariably require that reactivity be relayed from intermediate to intermediate over several mechanistic steps until a termination event produces the final product. Here we report a multicomponent process in which a novel 1,2,3-butatriene equivalent (TMSBO: TMSCH2C≡CCH2OH) engages chemospecifically as a two-carbon alkyne component in a metal-catalyzed [5+2] cycloaddition with a vinylcyclopropane to produce an intermediate cycloadduct. Under the reaction conditions, this intermediate undergoes a remarkably rapid 1,4-Peterson elimination, producing a reactive four-carbon diene intermediate that is readily intercepted in either a metal-catalyzed or thermal [4+2] cycloaddition. TMSBO thus serves as an yne-to-diene transmissive reagent coupling two powerful and convergent cycloadditions - the homologous Diels-Alder and Diels-Alder cycloadditions - through a vinylogous Peterson elimination, and enabling flexible access to diverse polycycles.

  14. Adsorption of anionic azo-dyes from aqueous solutions onto graphene oxide: Equilibrium, kinetic and thermodynamic studies. (United States)

    Konicki, Wojciech; Aleksandrzak, Małgorzata; Moszyński, Dariusz; Mijowska, Ewa


    In the present study, graphene oxide (GO) was used for the adsorption of anionic azo-dyes such as Acid Orange 8 (AO8) and Direct Red 23 (DR23) from aqueous solutions. GO was characterized by Fourier Transform-Infrared Spectroscopy (FTIR), X-ray Photoelectron Spectroscopy (XPS), Thermogravimetric Analysis (TGA), Atomic Force Microscopy (AFM), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), High-Resolution Transmission Electron Microscopy (HRTEM) and zeta potential measurements. The influence of dye initial concentration, temperature and pH on AO8 and DR23 adsorption onto GO was investigated. Equilibrium data were analyzed by model equations such as Langmuir Freundlich, Temkin, Dubinin-Radushkevich and Redlich-Peterson isotherms and were best represented by Langmuir and Redlich-Peterson isotherm model. Kinetic adsorption data were analyzed using the pseudo-first-order kinetic model, the pseudo-second-order kinetic model and the intraparticle diffusion model. The adsorption kinetics well fitted using a pseudo-second-order kinetic model. Thermodynamics parameters, ΔG°, ΔH° and ΔS°, were calculated, indicating that the adsorption of AO8 and DR23 onto GO was spontaneous process. The adsorption process of AO8 onto GO was exothermic, while the adsorption of DR23 onto GO was endothermic in nature. Copyright © 2017 Elsevier Inc. All rights reserved.

    The present work focused on the performance of Polyaniline/SiO 2 nanocomposite for removing Amido Black 10B dye from aqueous solution. The effect of different variables, such as adsorption time, the mass of adsorbent, solution pH and initial dye concentration was studied and also was optimized by an Artificial Neural Network (ANN) method. Lagergren, pseudo-second order, Intra-particle Diffusion, Elovich and Boyd models were tested to track the kinetics of the adsorption process. The experimental data were fitted to different two-parameter, and three-parameter isotherm models, namely, Langmuir, Freundlich, Temkin, D-R, Hill, Sips and Redlich-Peterson models, and their validity was examined. The results showed that the dye adsorption process was well described by Redlich-Peterson isotherm model. Thermodynamic studies revealed that the adsorption of Amido Black 10B onto Polyaniline/SiO 2 nanocomposite was endothermic. The comparison of the adsorption efficiencies obtained by the ANN model and the experimental data evidenced that the ANN model could estimate the behavior of the Amido Black 10B dye adsorption process under various conditions.

Dept. - Steward Observ. /Princeton U. Observ. /Johns Hopkins U. /UC, Berkeley, Astron. Dept. /UC, Davis


    We present the discovery of seven quasars at z > 5.7, selected from {approx}2000 deg{sup 2} of multicolor imaging data of the Sloan Digital Sky Survey (SDSS). The new quasars have redshifts z from 5.79 to 6.13. Five are selected as part of a complete flux-limited sample in the SDSS Northern Galactic Cap; two have larger photometric errors and are not part of the complete sample. One of the new quasars, SDSS J1335+3533 (z = 5.93), exhibits no emission lines; the 3-{sigma} limit on the rest-frame equivalent width of Ly{alpha} + NV line is 5 {angstrom}. It is the highest redshift lineless quasar known, and could be a gravitational lensed galaxy, a BL Lac object or a new type of quasar. Two new z > 6 quasars, SDSS 1250+3130 (z = 6.13) and SDSS J1137+3549 (z = 6.01), show deep Gunn-Peterson absorption gaps in Ly{alpha}. These gaps are narrower the complete Gunn-Peterson absorption troughs observed among quasars at z > 6.2 and do not have complete Ly{beta} absorption.

  17. Warm Dark Matter and Cosmic Reionization (United States)

    Villanueva-Domingo, Pablo; Gnedin, Nickolay Y.; Mena, Olga


    In models with dark matter made of particles with keV masses, such as a sterile neutrino, small-scale density perturbations are suppressed, delaying the period at which the lowest mass galaxies are formed and therefore shifting the reionization processes to later epochs. In this study, focusing on Warm Dark Matter (WDM) with masses close to its present lower bound, i.e., around the 3 keV region, we derive constraints from galaxy luminosity functions, the ionization history and the Gunn–Peterson effect. We show that even if star formation efficiency in the simulations is adjusted to match the observed UV galaxy luminosity functions in both CDM and WDM models, the full distribution of Gunn–Peterson optical depth retains the strong signature of delayed reionization in the WDM model. However, until the star formation and stellar feedback model used in modern galaxy formation simulations is constrained better, any conclusions on the nature of dark matter derived from reionization observables remain model-dependent.

  18. [The key points of prevention for special surgical complications after radical operation of gastric cancer]. (United States)

    Xu, Hao; Wang, Weizhi; Li, Panyuan; Zhang, Diancai; Yang, Li; Xu, Zekuan


    Incidence of gastric cancer is high in China and standard radical operation is currently the main treatment for gastric cancer. Postoperative complications, especially some special complications, can directly affect the prognosis of patients, even result in the increase of mortality. But the incidences of these special complications are low, so these complications are often misdiagnosed and delayed in treatment owing to insufficient recognition of medical staff. These special complications include (1) Peterson hernia: It is an abdominal hernia developed in the space between Roux loop and transverse colon mesentery after Roux-Y reconstruction of digestive tract. Peterson hernia is rare and can quickly result in gangrenous ileus. Because of low incidence and without specific clinical symptoms, this hernia does not attract enough attention in clinical practice, so the outcome will be very serious. Once the diagnosis is made, an emergent operation must be performed immediately. Peterson space should be closed routinely in order to avoid the development of hernia. (2) Lymphatic leakage: It is also called chyle leakage. Cisterna chylus is formed by gradual concentration of extensive lymphatic net to diaphragm angle within abdominal cavity. Lymphadenectomy during operation may easily damage lymphatic net and result in leakage. The use of ultrasonic scalpel can decrease the risk of lymphatic leakage in certain degree. If lymphatic leakage is found during operation, transfixion should be performed in time. Treatment includes total parenteral nutrition, maintenance of internal environment, supplement of protein, and observation by clamp as an attempt. (3)Duodenal stump leakage: It is one of serious complications affecting the recovery and leading to death after subtotal gastrectomy. Correct management of duodenal stump during operation is one of key points of the prevention of duodenal stump leakage. Routine purse embedding of duodenal stump is recommend during operation

    Directory of Open Access Journals (Sweden)

    A. Edwin Vasu


    Full Text Available A commercial activated carbon was utilized for the adsorptive removal of phenol and o-cresol from dilute aqueous solutions. Batch mode adsorption studies were performed by varying parameters such as concentration of phenol solution, time, pH and temperature. The well known Freundlich, Langmuir and Redlich-Peterson isotherm equations were applied for the equilibrium adsorption data and the various isotherm parameters were evaluated. The Langmuir monolayer adsorption capacities were found to be 0.7877 and 0.5936 mmole/g, respectively, for phenol and o-cresol. Kinetic studies performed indicate that the sorption processes can be better represented by the pseudo-second order kinetics. The processes were found to be endothermic and the thermodynamic parameters were evaluated. Desorption studies performed indicate that the sorbed phenol molecules can be desorbed with dil. HCl.

  20. Assessment of attention and memory efficiency in persons with solvent neurotoxicity. (United States)

    Morrow, L A; Robin, N; Hodgson, M J; Kamis, H


    Memory and attention were evaluated in 40 persons with a history of organic solvent exposure and 40 demographically similar controls. Exposed subjects, in comparison to controls, had reduced digit spans, were deficient at learning new information, and recall on a Brown-Peterson distractor test was especially low following a 30-sec interference interval. If original learning was considered, long-term recall was similar for both groups. On a test of sustained attention, the Continuous Performance Test, exposed subjects became less accurate over successive blocks, a pattern opposite to that seen in control subjects. The data suggest that the memory impairment following solvent exposure may result from deficient allocation of attentional resources due to the inability to deal effectively with an increase in processing load.

    Brdar, R; Petronic, I; Abramovic, D; Nikolic, D; Lukac, M; Cirovic, D


    The purpose of our study was to present results of different surgical orthopaedic approaches in the treatment of children with developmental hip disorder. At the University Childrens Hospital in Belgrade, 21 young adults diagnosed with developmental hip disorder were treated with double osteotomy and with a modified Smith-Peterson approach during a period of 10 years, from 1997 to 2007. All patients were clinically and radiographically evaluated. We were successful with 23 hips in 20 patients, since some patients underwent surgery of both hips. The evaluation of improvement was done according to the Merle d'Aubigne and Postel system which indicated very satisfied outcome in five patients, satisfied in 8, fair in 7 and poor in one patient. In this paper we discuss the advantages and disadvantages of double osteotomy procedures compared with others that are used in the correction of developmental hip disorder. The best solution is adequate and timely diagnosis with proper correction of the deformity.

    Full Text Available Abstract: Comparison of methods of adaptability and stability has raised interest, and there are SOME studies dealing on the subject; with that, this study aimed to estimate the correlation coefficient for adaptability and stability parameters in regions of degraded areas for grain yield, using competition experiments of soybean genotypes in the agricultural years of 2009-2010 and 2010-2011 in the municipalities of Gurupi and Palmas – State of Tocantins-TO, Brazil. The association among the mean and the methodologies of Plaisted and Peterson, Wricke, Annicchiarico, Finlay and Wilkinson, Eberhart and Russell, Tai Lin and Binns modified by Carneiro and Centroid was verified by Spearman’s Correlation Coefficient. The methods of Plaisted, Peterson, and Wricke are associated with the highest stability and they are independent of adaptability to general, favorable, and unfavorable environment and should be used with restraint. Cultivars with high yield and adapted to favorable environments may be the best indicated alternative according to the method developed by Lin and Binns modified by Carneiro, Annicchiarico, and Centroid. The method of Eberhart and Russell may preferably be used for considering the productivity, stability, and adaptability simultaneously to general, favorable, and unfavorable environments The simultaneous use of Lin and Binns’ methodologies modified by Carneiro, Annicchiarico, Centroid, and Eberhart and Russell can assist in selecting the promising genotypes for regions of degraded areas of the Amazonian “cerrado. = A comparação entre metodologias de adaptabilidade e estabilidade tem levantado interesse, existindo diversos trabalhos tratando sobre o assunto, com isso, objetivou-se com este trabalho estimar o coeficiente de correlação para parâmetros de adaptabilidade e estabilidade em regiões de áreas degradadas para a produtividade de grãos, através de ensaios de competição de genótipos de soja nos anos agr

    DEFF Research Database (Denmark)

    Greiner, J.; Krühler, T.; Fynbo, J. P. U.


    We report on the detection by Swift of GRB 080913, and subsequent optical/near-infrared follow-up observations by GROND, which led to the discovery of its optical/NIR afterglow and the recognition of its high-z nature via the detection of a spectral break between the i' and z' bands. Spectroscopy...... obtained at the ESO-VLT revealed a continuum extending down to ¿ = 9400 Å, and zero flux for 7500 Åinterpret as the onset of a Gunn-Peterson trough at z = 6.695± 0.025 (95.5% confidence level), making GRB 080913 the highest-redshift gamma-ray burst (GRB) to date, and more distant than...

  6. Flexible word classes in linguistic typology and grammatical theory

    DEFF Research Database (Denmark)


    Currently one of the most controversial topics in linguistic typology and grammatical theory concerns the existence of FLEXIBLE LANGUAGES, i.e. languages with a word class whose members cover functions that are typically associated with two or more of the traditional word classes (verb, noun...... to integrate the individual chapters under a single theoretical approach. It rather presents a wide range of novel descriptive facts and shows how some grammatical theories could accommodate these facts.3 Some of the chapters are primarily theoretically and typologically oriented, taking into account several...... languages (see esp. the contribution by Hengeveld; also those by Don and van Lier; Bisang). Other chapters combine a theoretical analysis with the description of flexibility in a single language (chapters by Gil, Peterson, and McGregor). Finally, a number of case studies of individual languages illustrate...

    Bleacher, L. V.; Peterson, K. A.; Sharma, M.; Smith, D.


    This two-hour workshop, which was held as a follow-on to the plenary session "Engaging Girls in STEM: A Discussion of Foundational and Current Research on What Works," offered research-based insights, resources, and tips to help participants plan or revamp programs and resources aimed at encouraging girls in science. Led by Karen Peterson, PI for the National Girls Collaborative Project,1 the workshop included: a brief discussion about effective strategies recommended for encouraging girls in STEM; hands-on experience, where participants - availing of the expert's guidance - applied the recommended strategies to alter or tailor an existing or planned program/resource to be more girl-friendly; and a sharing out, where the participants reflected on the results of the hands-on exercise and developed action items to continue carrying out the girl-friendly best practices in science, technology, engineering, and math education and public outreach.

  8. Adsorption of Ni(II, Cu(II and Fe(III from Aqueous Solutions Using Activated Carbon

    Directory of Open Access Journals (Sweden)

    A. Edwin Vasu


    Full Text Available An activated carbon was tested for its ability to remove transition metal ions from aqueous solutions. Physical, Chemical and liquid-phase adsorption characterizations of the carbon were done following standard procedures. Studies on the removal of Ni(II, Cu(II and Fe(III ions were attempted by varying adsorbate dose, pH of the metal ion solution and time in batch mode. The equilibrium adsorption data were fitted with Freundlich, Langmuir and Redlich-Peterson isotherms and the isotherm constants were evaluated. Time variation studies indicate that adsorptions follow pseudo-second order kinetics. pH was found to have a significant role to play in the adsorption. The processes were endothermic and the thermodynamic parameters were evaluated. Desorption studies indicate that ion-exchange mechanism is operating.

  9. Surface Modification Effects on CNTs Adsorption of Methylene Blue and Phenol

    Directory of Open Access Journals (Sweden)

    A. H. Norzilah


    Full Text Available This study compares the adsorption capacity of modified CNTs using acid and heat treatment. The CNTs were synthesized from acetone and ethanol as carbon sources, using floating catalyst chemical vapor deposition (FC-CVD method. energy-dispersive X-ray spectroscopy (EDX and Boehm method revealed the existence of oxygen functional group on the surface of CNTs. Heat modification increases the adsorption capacity of as-synthesized CNTs for methylene blue (MB and phenol by approximately 76% and 50%, respectively. However, acid modification decreases the adsorption capacity. The equilibrium adsorption data fitted the Redlich-Peterson isotherm. For the adsorption kinetic study, the experimental data obeyed the pseudo-second-order model. Both modifications methods reduced the surface area and pore volume. The studies show that the adsorption of MB and phenol onto modified CNTs is much more influenced by their surface functional group than their surface area and pore volume.

    I report some results of an echelle spectroscopic survey of RR Lyrae stars begun in 2006 that I presented in my Henry Norris Lecture of 2010 January 4. Topics include (1) atmospheric velocity gradients, (2) phase-dependent envelope turbulence as it relates to Peterson's discoveries of axial rotation on the horizontal branch and to Stothers' explanation of the Blazhko effect, (3) the three apparitions of hydrogen emission during a pulsation cycle, (4) the occurrence of He I lines in emission and absorption, (5) detection of He II emission and metallic line doubling in Blazhko stars, and finally (6) speculation about what helium observations of RR Lyrae stars in omega Centauri might tell us about the putative helium populations and the horizontal branch of that strange globular cluster.

  11. An example of age-associated interference in memorizing. (United States)

    Schonfield, A E; Davidson, H; Jones, H


    The study compared young and old intellectually superior individuals (mean ages 22.8 and 68.8) on Brown-Peterson memory tasks. Each trial required recall of four words following 15 seconds of backward counting, with a final recognition test for words in a 4-trial block. Each person participated in a switch and nonswitch condition of a Wickens paradigm--unchanged category membership of quadruplets for nonswitch and trial 4 change for switch. Usual recall loss from trial 2 onwards and recovery on trial 4 after a switch was found in both age groups, but significantly lower recall was shown by the old on trial 3 and also on trial 4 in the nonswitch condition. Recognition by the young was almost perfect, but the old had lower scores for words presented on trials 3 and 4 (nonswitch). All memory interference in young adults could, therefore, be attributed to retrieval difficulty, but a residual proactive deficit occurs in old adults.

    Rotational transitions in molecular hydrogen collisions are computed. The two most recently developed potential energy surfaces for the H 2 -H 2 system are used from the following works: [A.I. Boothroyd, P.G. Martin, W.J. Keogh, M.J. Peterson, J. Chem. Phys., 116 (2002) 666; P. Diep, J.K. Johnson, J. Chem. Phys., 113 (2000) 3480; P. Diep, J.K. Johnson, J. Chem. Phys., 112 (2000) 4465]. Cross-sections for rotational transitions 00 → 20, 22, 40, 42, 44 and corresponding rate coefficients are calculated using a quantum-mechanical approach. Results are compared for a wide range of kinetic temperatures 300 K ≤ T≤ 3000 K

  13. Don't be the "Fifth Guy": Risk, Responsibility, and the Rhetoric of Handwashing Campaigns. (United States)

    Brown, M M


    In recent years, outbreaks such as H1N1 have prompted heightened efforts to manage the risk of infection. These efforts often involve the endorsement of personal responsibility for infection risk, thus reinforcing an individualistic model of public health. Some scholars-for example, Peterson and Lupton (1996)-term this model the "new public health." In this essay, I describe how the focus on personal responsibility for infection risk shapes the promotion of hand hygiene and other forms of illness etiquette. My analysis underscores the use of constitutive and stigmatizing rhetoric to depict individual bodies, rather than environments, as prime sources of infection. Common among workplaces, this rhetoric provides the impetus for encouraging individual behavior change as a hedge against infection risk. I argue, though, that the mandating of personal responsibility for infection risk galvanizes a culture of stigma and blame that may work against the aims of public health.

  14. An application of data envelopment analysis for measuring the relative efficiency in banking industry

    Mehdi Soltanifar


    Full Text Available Measuring the relative efficiency of banking industry has been a popular subject among both practitioners and academicians. Data envelopment analysis (DEA has been widely applied for different purposes. This paper presents an empirical investigation to measure the relative efficiency of various banks located in province of Semnan, Iran. The proposed study uses DEA method to rank all units and using Anderson and Peterson method (1993 [Andersen, P., & Petersen, N. C. (1993. A procedure for ranking efficient units in data envelopment analysis. Management Science, 39, 1261-1264], we provide some super efficiency for inefficient units. The study also provides reference numbers for inefficient units and gives some target values for all inefficient units.

  15. Waste Plant Material as a Potential Adsorbent of a Selected Azo Dye

    Directory of Open Access Journals (Sweden)

    Tomczak Elwira


    Full Text Available This paper discusses the adsorption of Direct Orange 26 azo dye on sunflower husk - an agricultural waste product. During the study, sorption kinetics and equilibrium as well as sorption capacity of the husk were investigated. The adsorption kinetics was analyzed using pseudo-first and pseudo-second order equations, which indicated a chemical sorption mechanism. The sorption equilibrium was approximated with the two-parameter Freundlich and Langmuir equations and the three-parameter Redlich-Peterson equation. The main experiments were carried out in a laboratory adsorption column under different process conditions. Experimental data were interpreted with the Thomas model, based on the volumetric flow rate, initial composition of the feed solution and mass of the adsorbent. The results of modeling the adsorption equilibrium, adsorption kinetics and adsorption dynamics were evaluated statistically.

  16. Elastic tracking versus neural network tracking for very high multiplicity problems

    International Nuclear Information System (INIS)

    Harlander, M.; Gyulassy, M.


    A new Elastic Tracking (ET) algorithm is proposed for finding tracks in very high multiplicity and noisy environments. It is based on a dynamical reinterpretation and generalization of the Radon transform and is related to elastic net algorithms for geometrical optimization. ET performs an adaptive nonlinear fit to noisy data with a variable number of tracks. Its numerics is more efficient than that of the traditional Radon or Hough transform method because it avoids binning of phase space and the costly search for valid minima. Spurious local minima are avoided in ET by introducing a time-dependent effective potential. The method is shown to be very robust to noise and measurement error and extends tracking capabilities to much higher track densities than possible via local road finding or even the novel Denby-Peterson neural network tracking algorithms. 12 refs., 2 figs

  17. Influence of timing of two-stage palate closure on early phonological and lexical development in children with cleft palate

    DEFF Research Database (Denmark)

    Willadsen, Elisabeth

      BACKGROUND AND PURPOSE Numerous studies have indicated that early closure of the palatal cleft has a positive influence on the phonological development in children with cleft palate. So far, however, substantial evidence for this assumption has been lacking due to a variety of weaknesses...... of the studies conducted, including the lack of randomized clinical trials (RCT) (Peterson-Falzone 1996). A  prospective RCT was conducted to add to the knowledge of the influence of timing of hard palate closure on early phonological and lexical development from 1 to 3 years. METHODS Fourty-one children...... were video-recorded during a play interaction with a parent, and the video-recordings were transcribed in IPA. At 36 months, a naming test was administered. RESULTS At 18 months, the phonological development in the early group was more similar to that of the control group, than that of the late group...

  18. Self-Assessment Of Personal Virtues and its Correlation to the Basic Beliefs and Values

    Directory of Open Access Journals (Sweden)

    Sergey A. Bogomaz


    Full Text Available The purpose of this paper is to describe the results of empirical research of the personal values as bases for self-assessments of some personal virtues. The study is implemented in line with positive psychology, and is based on the concept of values as basic foundations of a particular human actions. The empirical research of a self-assessment of expressiveness of personal values at 658 residents of 4 Siberian cities of Russia. (Tomsk, Kemerovo, Barnaul, Lesosibirsk was carried out in 2013-2014 with the use of the technique the "Questionnaire of 24 virtues" developed by E.N. Osin on the basis of a questionnaire "A profile of personal values" of K. Peterson and M. Seligman's Values-In-Action. The results of cluster and correlation analysis were presented, allowing to isolate distinct groups of the virtues in a sample and to connect these to the basic beliefs and values.

  19. Enthalpy of Formation of N2H4(Hydrazine) Revisited. (United States)

    Feller, David; Bross, David H; Ruscic, Branko


    In order to address the accuracy of the long-standing experimental enthalpy of formation of gas-phase hydrazine, fully confirmed in earlier versions of Active Thermochemical Tables (ATcT), the provenance of that value is re-examined in light of new high-end calculations of the Feller-Peterson-Dixon (FPD) variety. An overly optimistic determination of the vaporization enthalpy of hydrazine, which created an unrealistically strong connection between the gas phase thermochemistry and the calorimetric results defining the thermochemistry of liquid hydrazine, was identified as the probable culprit. The new enthalpy of formation of gas-phase hydrazine, based on balancing all available knowledge, was determined to be 111.57 ± 0.47 kJ/mol at 0 K (97.42 ± 0.47 kJ/mol at 298.15 K). Close agreement was found between the ATcT (even excluding the latest theoretical result) and the FPD enthalpy.

  20. [Dialogue as a pressuposition in the humanistic nursing theory: relationship mother-nurse-newborn]. (United States)

    Lúcio, Ingrid Martins Leite; Pagliuca, Lorita Marlena Freitag; Cardoso, Maria Vera Lúcia Moreira Leitão


    This is a critical-reflective study carried out in 2005 aiming at analyzing dialogue as a presupposition in Peterson and Zderad's Humanistic Theory. Using as a starting point two Master's degree theses, the authors adopted the Meleis Model of Analysis, in the scope of theory description, focusing on the unit of analysis named theory presuppositions. The authors clearly perceive the quest for and the construction of the dialogue in the stages of the theory's methodological process: Preparation in order to get to know, Knowing the other intuitively, Knowing the other scientifically, Complementary synthesis of the others' knowledge, Succession within the nurse from the many to the paradoxical one. The presupposition of dialogue was brought up in an explicit manner in the theory, grounded on the philosophical bases of existentialism, humanism, and phenomenology. There was a distinct behavior in each experience, in spite of the common aspects, such as having been experienced with neonates and in the same institution.

  2. New Measurements of the Cosmic Background Radiation Temperature at3.3 mm Wavelength

    Energy Technology Data Exchange (ETDEWEB)

    Witebsky, C.; Smoot, G.; De Amici, G.; Friedman, S.D.


    We have measured the temperature of the cosmic background radiation (CBR) at 3.3 mm wavelength in 1982, 1983, and 1984 as part of a larger project to determine the CBR temperature at five wavelengths from 12 cm to 3.3 mm (Smoot et al. 1985). The 3.3-mm measurements yield a brightness temperature of 2.57 K with a 1{sigma} uncertainty of 20.12 K. This paper describes the instrument, the measurement techniques, and the data-analysis procedures used. Our result is in good agreement with recent measurements at comparable wavelengths by Meyer and Jura (1985) and by Peterson, Richards, and Timusk (1985), but it disagrees with the temperatures reported by Woody and Richards (1981).

  3. Black-hole thermodynamics and Riemann surfaces

    International Nuclear Information System (INIS)

    Krasnov, Kirill


    We use the analytic continuation procedure proposed in our earlier works to study the thermodynamics of black holes in 2 + 1 dimensions. A general black hole in 2 + 1 dimensions has g handles hidden behind h horizons. The result of the analytic continuation of a black-hole spacetime is a hyperbolic 3-manifold having the topology of a handlebody. The boundary of this handlebody is a compact Riemann surface of genus G = 2g + h - 1. Conformal moduli of this surface encode in a simple way the physical characteristics of the black hole. The moduli space of black holes of a given type (g, h) is then the Schottky space at genus G. The (logarithm of the) thermodynamic partition function of the hole is the Kaehler potential for the Weil-Peterson metric on the Schottky space. The Bekenstein bound on the black-hole entropy leads us to conjecture a new strong bound on this Kaehler potential

  4. Using multiple risk factors to assess the behavioral, cognitive, and affective effects of learned helplessness. (United States)

    McKean, K J


    Rather than examining the effect of the pessimistic explanatory style on an outcome variable reflecting a single domain, I studied the effects of multiple learned-helplessness risk factors on behavioral, cognitive, and affective variables. Undergraduate students completed the Learned Helplessness Scale (Quinless & McDermott-Nelson, 1988) as a measure of their expectation of uncontrollability and the Explanatory Style Questionnaire (Peterson et al., 1982) to determine their explanations for both positive and negative events. Results revealed a significant effect for risk level, with students at greater risk of helplessness reporting significantly more procrastination, lower grade point averages, and more dysphoria. These results support the use of multiple risk factors representing all learned-helplessness precursors and the assessment of learned-helplessness deficits drawn simultaneously from behavioral, cognitive, and affective domains.

    Linnet J, Peterson E, Doudet DJ, Gjedde A, Møller A. Dopamine release in ventral striatum of pathological gamblers losing money. Objective: To investigate dopaminergic neurotransmission in relation to monetary reward and punishment in pathological gambling. Pathological gamblers (PG) often continue...... gambling despite losses, known as 'chasing one's losses'. We therefore hypothesized that losing money would be associated with increased dopamine release in the ventral striatum of PG compared with healthy controls (HC).

    Full Text Available No abstract available. Article truncated at 150 words. The October 2015 pulmonary journal club focused on the review of older studies evaluating lung volume reduction surgery and how this has transitioned toward the development of non-surgical modes of lung volume reduction. The physiology behind dyspnea in chronic obstructive pulmonary disease (COPD is a complex process. One of the proposed mechanisms has been hyperinflation associated with air trapping. In the mid 1990s studies by Cooper and Peterson (1 offered a promising approach in which lung volume reduction (LVR could improve ventilatory mechanics and improve dyspnea. As the procedure gained more popularity, additional larger scale trials were performed to support its validity. We reviewed 2 studies looking at lung volume reduction. The first was "The Effect of Lung Volume Reduction Surgery In Patients With Severe Emphysema” (2 . This was a smaller, randomized controlled trial (RCT that looked at 2 groups of 24 patients.

  7. The relative impacts of uncertainty and mothers' communication on hopelessness among Palestinian refugee youth. (United States)

    Afifi, Walid A; Afifi, Tamara D; Robbins, Stephanie; Nimah, Najib


    The life of adolescent refugees has been described as uncertainty laden. Yet no quantitative data exist to elucidate that experience of uncertainty, investigate its implications in that population, or explore potential moderators. This study applies the Entropy Model of Uncertainty (Hirsh, Mar, & Peterson, 2012) and the stress-buffering hypothesis (for review, see Hegelson, 2003) to examine the experience of uncertainty among adolescent Palestinians living in refugee camps in Lebanon. It then tests the role of mothers' uncertainty-related communication for adolescent hopelessness. One hundred and sixty-two adolescents across 2 refugee camps in Lebanon participated in the study. Results support the existence of elevated levels of uncertainty about both personal and macrosecurity, show an association between uncertainty regarding personal security and levels of hopelessness, and suggest that uncertainty's negative impact may overwhelm the role of mothers' supportive communication as a buffer against hopelessness. Interestingly, the data also suggest surprisingly little hopelessness in this population. © 2013 American Orthopsychiatric Association.

  9. Reionization in a cold dark matter universe: The feedback of galaxy formation on the intergalactic medium (United States)

    Shapiro, Paul R.; Giroux, Mark L.; Babul, Arif


    We study the coupled evolution of the intergalactic medium (IGM) and the emerging structure in the universe in the context of the cold dark matter (CDM) model, with a special focus on the consequences of imposing reionization and the Gunn-Peterson constraint as a boundary condition on the model. We have calculated the time-varying density of the IGM by coupling our detailed, numerical calculations of the thermal and ionization balance and radiative transfer in a uniform, spatially averaged IGM of H and He, including the mean opacity of an evolving distribution of gas clumps which correspond to quasar absorption line clouds, to the linearized equations for the growth of density fluctuations in both the gaseous and dark matter components in a CDM universe. We use the linear growth equations to identify the fraction of the gas which must have collapsed out at each epoch, an approach similar in spirit to the so-called Press-Schechter formalism. We identify the IGM density with the uncollapsed baryon fraction. The collapsed fraction is postulated to be a source of energy injection into the IGM, by radiation or bulk hydrodynamical heating (e.g., via shocks) or both, at a rate which is marginally enough to satisfy the Gunn-Peterson constraint at z less than 5. Our results include the following: (1) We find that the IGM in a CDM model must have contained a substantial fraction of the total baryon density of the universe both during and after its reionization epoch. (2) As a result, our previous conclusion that the observed Quasi-Stellar Objects (QSOs) at high redshift are not sufficient to ionize the IGM enough to satisfy the Gunn-Peterson constraint is confirmed. (3) We predict a detectable He II Gunn-Peterson effect at 304(1 + z) A in the spectra of quasars at a range of redshift z greater than or approx. 3, depending on the nature of the sources of IGM reionization. (4) We find, moreover, that a CDM model with high bias parameter b (i.e., b greater than or approx. 2

In this paper we exploit a unique series of surveys on cultural participation collected in Denmark in the period 1964-2004 (1964, 1975, 1987, 1993, 1998, and 2004) to map the historical development of the omnivorous cultural consumer. In addition, we analyze how a range of social stratification......, income, and education are strong predictors of cultural omnivorousness but furthermore that the strength of these social stratification variables has been declining over the past 40 years.......In their seminal work Peterson and Kern (1996) reported that the system of cultural stratification in the USA was characterized by omnivorous cultural consumers in 1982, a pattern that grew stronger in 1992. Subsequent research has shown that an omnivorous consumer also existed in many other...

  14. Our Experience with Double Metatarsal Osteotomy in the Treatment of Hallux Valgus

    Directory of Open Access Journals (Sweden)

    Pradeep George Mathew


    Full Text Available Adolescent hallux valgus (HV is a progressive deformity of adolescent age consisting of metatarsus primus varus and hallux valgus. It has a high recurrence rate after conventional surgical correction. Ten feet in nine patients (two males, seven females were treated surgically with the Peterson Newman bunion procedure, with a minimum follow‑up of one year. During the final follow‑up all these patients had no complaints of pain, joint stiffness or limping. Even though the patients had some mild loss of range of movements at the MTP joints 4–6° compared to preoperative value, it did not cause any functional impairment and all were satisfied with the final outcome. The double ostetomy for treatment of hallux valgus is technically precise procedure, provides excellent correction and stability and has low rate of recurrence of deformity. We had an excellent outcome in 10 feet in our study without residual deformity or complications.

  15. On Having Faith in the MDGs: A Response to Katherine Marshall (abstract

    Directory of Open Access Journals (Sweden)

    Philip Fountain


    Full Text Available Katherine Marshall’s thorough and thoughtful critique of my chapter raises a number of important objections. However, it appears that among her most important criticisms is that I didn’t write a different chapter. To clarify, my chapter was not a general survey of the literature on ‘religion and development’ (which has already been admirably carried out by Jones and Peterson, whom I cited. It was also not an attempt to present a systematic analysis of Marshall’s substantial corpus and its evolution over time. Nor, indeed, was it intended to be a comprehensive and detailed proposal as to where to go from here. These are all useful and valuable tasks – some are arguably more pressing than the argument I provided – but none were the goals of the chapter. (…

  1. Computer-assisted mechanistic evaluation of organic reactions

    Energy Technology Data Exchange (ETDEWEB)

    Gushurst, A.J.


    CAMEO, an interactive computer program which predicts the products of organic reactions given starting materials and conditions, has been refined and extended in the area of base-catalyzed and nucleophilic processes. The present capabilities of the program are outlined including brief discussion on the major segments in CAMEO: graphics, perception, and reaction evaluation. The implementation of general algorithms for predicting the acidities of a vast number of organic compounds to within 2 pK{sub a} units in dimethylsulfoxide and water are then described, followed by a presentation of the reactivity rules used by the program to evaluate nucleophilc reactions. Finally, a treatment of sulfur and phosphorus ylides, iminophosphoranes, and P=X-activated anions is given illuminating the various competitions available for these reagents, such as between proton transfer and addition, 1,2- and 1,4-addition, and the Peterson, Wittig, and Horner-Emmons olefination reactions.

  2. Monte Carlo simulation of turbulent atmospheric transport and comparisons with experimental data. [/sup 41/Ar continuously emitted from BNL reactor to atmosphere

    Energy Technology Data Exchange (ETDEWEB)

    Alsmiller, F. S.; Alsmiller, Jr., R. G.; Bertini, H. W.; Begovich, C. L.


    In a previous paper Peterson presented measurements on the /sup 41/Ar emitted continuously into the atmosphere from a reactor at the Brookhaven National Laboratory. Here, calculated results obtained with the Monte Carlo atmospheric transport model of Watson and Barr are presented and compared with the experimental data. The measured quantities with which comparisons are made are: the position north of Brookhaven where the maximum /sup 41/Ar concentration occurred for specific values of x (east of Brookhaven) and t, time; the standard deviation, sigma/sub y/, of the /sup 41/Ar concentration about the position of maximum concentration for specific values of x and t; and a quantity that is proportional to the maximum /sup 41/Ar concentration for specific values of x and t. The calculated results are in moderately good agreement with the experimental data at most distances (less than or equal to 300 km) and most times for which data are available.

  3. Tyre char preparation from waste tyre rubber for dye removal from effluents. (United States)

    Mui, Edward L K; Cheung, W H; McKay, Gordon


    A number of chars from waste tyre rubber were prepared by carbonisation at 673-1173 K. The effects of holding time, heating rate and particle size on the textural characteristics and elemental composition of the resultant chars were investigated. It was demonstrated that temperatures over 773 K did not have a significant improvement on the total surface area but resulted in lower char yields following increased aromatisation. Modelling of dye adsorption isotherms showed that the Redlich-Peterson expression yields the best-fit between experimental and predicted data. Furthermore, for a larger sized dye like Acid Yellow 117 (MW=848 g/mol), the amount adsorbed by the tyre char is not directly proportional to the total surface area when compared with a commercial carbon, revealing that factors other than total surface area are involved in the adsorption potential of the tyre chars.

  4. Mean stress effects on high-cycle fatigue of Alloy 718

    International Nuclear Information System (INIS)

    Korth, G.E.


    This report covers an investigation of the effects of tensile mean stress on the high-cycle fatigue properties of Alloy 718. Three test temperatures (24, 427, and 649 degree C) were employed, and there were tests in both strain and load control. Results were compared with three different models: linear Modified-Goodman, Peterson cubic, and stress-strain parameter. The linear Modified-Goodman model gave good correlation with actual test data for low and moderate mean stress values, but the stress-strain parameter showed excellent correlation over the entire range of possible mean stresses and therefore is recommended for predicting mean stress effects of Alloy 718. 13 refs., 12 figs

  5. Egyptian activists and state supporting media

    DEFF Research Database (Denmark)

    Mollerup, Nina Grønlykke

    Mark Allen Peterson (2011) has argued for seeing revolutions as periods of liminality, maintaining that unlike traditional rites of passage, where the outcome of the process is known, the transformational possibilities in a social and political revolution seem endless. In this presentation, I argue...... that the uncertainties of the transformational possibilities encourage shifting and unlikely media alliances in which people, who would previously see themselves as fierce opponents momentarily find common objectives and cooperate around them. I look particularly at relationships between corporate journalists...... and activists from the No to Military Trials for Civilians campaign and Operation Anti Sexual Harassment and Assault (OpAntiSH) and describe their very different media dynamics. No to Military Trials for Civilians managed to get through to corporate media after months of insistent efforts and a substantial...

    Full Text Available There was conducted the simulations of a cochlea of an interior ear of the human by means of a long line. The following regularities of operation of a cochlea were determined: without the count of flexibilities Reissner's and basilar membranes swing pressure on walls of a cochlear course does not exceed 3,6 % from pressure in the field of an oval window; allocation of a differential of sound pressure fluctuates in a time with frequency; taking into account the slenderness of a membrane and dependence of a standing of resonances from f are spotted by non-uniformity of a basilar membrane; the differential travelling wave exists only near to a resonance on each  frequency where the amplitude buildup of oscillations to a maximum happens for many continuances of resonance frequency. Small relative meaning of range of pressure of travelling wave could become the parent of that Peterson's and Bogert's work has not had the further evolution.

  7. Estimation of the Scale of Fluctuation for Spatial Variables of RC Structures

    Directory of Open Access Journals (Sweden)

    Hilyati S.


    Full Text Available Dimensional and structural properties of RC structures are nonhomogenous due to the quality of workmanship, environmental and material variability. One of the required statistical information for spatial variability analysis of RC structures includes the scale of fluctuation, θ. This paper discusses the estimation of θ for two spatial variables; concrete compressive strength and concrete cover. Methods used to estimate the θ are the Curve fitting method and the Kriging Method. Kriging is an optimal interpolation method which uses the concept of randomness that allows the uncertainty of the predicted values to be calculated. Data measurements for concrete compressive strength and concrete cover were obtained from Peterson (1964 and Public Work Department of Malaysia respectively. The most reliable value for θ of fcu was determined and the value obtained for θ of c was found unreliable due to the insufficient of data points from the available data.

  8. Long-Term Perseveration in Alzheimer’s Disease: A Case Report

    Directory of Open Access Journals (Sweden)

    Edith V. Sullivan


    Full Text Available The most common clinical sign of Alzheimer's disease (AD is progressive memory loss. Presented here is a case of AD who, despite ultimate profound dementia with severe amnesia, showed retention of a perseverative response she developed during 26 encounters, over 4.5 years, with the Brown–Peterson distractor test. From Test 9 onwards, she responded from the first distractor-filled trial with one consonant trigram, appearing in none of the seven test forms given her. At Test 26, she could not repeat heard trigrams yet faithfully responded with her perseverative trigram. The trigram, ostensibly declarative information, apparently became part and parcel of the task's procedure. Although perseveration is a form of impairment probably resulting from Alzheimer pathology involving frontal and parietal cortex, it may also reflect a form of preserved memory, albeit distorted, supported by posterior cortical regions spared in AD.

  10. Understanding thermodynamic relationships and geochemical mass balances from catchment to coast: A tribute to the life and career of Owen P. Bricker III (United States)

    Bricker, Suzanne B.; Mackenzie, Fred T.; Baron, Jill S.; Price, Jason


    This special volume of aquatic geochemistry is dedicated to the memory of Owen Peterson Bricker III (1936–2011) and serves as a tribute to his life and career. Owen had a distinguished and productive research career in both academics at Johns Hopkins University (Fig. 1) and as a public servant with the Maryland Geological Survey, the US Environmental Protection Agency, and the US Geological Survey. He was a pioneer and leader in aqueous geochemistry, who applied a study approach that quantified mineral weathering reactions and equilibrium thermodynamic relations to better understand the chemical evolution of stream water in small watersheds. He will be especially remembered for his efforts to establish rigorous field studies in small catchments around the United States as a means of quantifying the sources of acid-neutralizing capacity that affect the chemical status and biological health of natural waters.

  12. Strengths only or strengths and relative weaknesses? A preliminary study. (United States)

    Rust, Teri; Diessner, Rhett; Reade, Lindsay


    Does working on developing character strengths and relative character weaknesses cause lower life satisfaction than working on developing character strengths only? The present study provides a preliminary answer. After 76 college students completed the Values in Action Inventory of Strengths (C. Peterson & M. E. P. Seligman, 2004), the authors randomly assigned them to work on 2 character strengths or on 1 character strength and 1 relative weakness. Combined, these groups showed significant gains on the Satisfaction With Life Scale (E. Diener, R. A. Emmons, R. J. Larsen, & S. Griffin, 1985), compared with a 32-student no-treatment group. However, there was no significant difference in gain scores between the 2-strengths group and the 1-character-strength-and-1-relative-character-weakness group. The authors discuss how focusing on relative character weaknesses (along with strengths) does not diminish-and may assist in increasing-life satisfaction.

  13. Overview of the Biomass Scenario Model

    Energy Technology Data Exchange (ETDEWEB)

    Peterson, Steve [Lexidyne, LLC, Colorado Springs, CO (United States)


    This report describes the structure of the October 2012 version of the Biomass Scenario Model (BSM) in considerable detail, oriented towards readers with a background or interest in the underlying modeling structures. Readers seeking a less-detailed summary of the BSM may refer to Peterson (2013). BSM aims to provide a framework for exploring the potential contribution of biofuel technologies to the transportation energy supply for the United States over the next several decades. The model has evolved significantly from the prototype developed as part of the Role of Biomass in America" tm s Energy Future (RBAEF) project. BSM represents the supply chain surrounding conversion pathways for multiple fuel products, including ethanol, butanol, and infrastructure-compatible biofuels such as diesel, jet fuel, and gasoline.

  14. Removal of Pyrethrin from Aqueous Effluents by Adsorptive Micellar Flocculation

    Directory of Open Access Journals (Sweden)

    Pardon K. Kuipa


    Full Text Available The equilibrium adsorption of pyrethrin onto aggregates formed by the flocculation of micelles of the surfactant sodium dodecyl sulphate (SDS with aluminium sulphate is reported. The experimental results were analysed using different adsorption isotherms (Langmuir, Freundlich, Redlich-Peterson, Sips, Radke-Prausnitz, Temkin, linear equilibrium, and the Dubin-Radushkevich isotherms. The Freundlich and linear equilibrium isotherms best describe the adsorption of pyrethrin onto SDS micellar flocs, with the Freundlich adsorption constant, KF, and the mass distribution coefficient, KD, of 64.266 ((mg/g(L/mg1/n and 119.65 L/g, respectively. Applicability of the Freundlich adsorption model suggests that heterogeneous surface adsorption affects the adsorption. The mean free energy value estimated using the Dubinin-Radushkevich isotherm was 0.136 kJ/mol indicating that physisorption may be predominant in the adsorption process.

    Aksu, Zuemriye [Hacettepe University, Department of Chemical Engineering, 06532 Beytepe, Ankara (Turkey)]. E-mail:; Isoglu, I. Alper [Hacettepe University, Department of Chemical Engineering, 06532 Beytepe, Ankara (Turkey)


    The potential use of dried sugar beet pulp, an agricultural solid waste by-product, as an biosorbent for Gemazol turquoise blue-G, a copper-pthalocyanine reactive dye commonly used in dyeing of cotton, was investigated in the present study. Batch adsorption studies were carried out to examine the influence of various parameters such as initial pH, temperature and initial dye concentration. The results indicated that adsorption was strongly pH-dependent and slightly temperature-dependent. At 800 mg l{sup -1} initial Gemazol turquoise blue-G concentration, dried sugar beet pulp exhibited the highest Gemazol turquoise blue-G uptake capacity of 234.8 mg g{sup -1} at 25 deg. C and at an initial pH value of 2.0. The Freundlich, Langmuir, Redlich-Peterson and Langmuir-Freundlich, the two and three parameters adsorption models were used for the mathematical description of the biosorption equilibrium and isotherm constants were evaluated depending on temperature. Both the Langmuir and Redlich-Peterson models were applicable for describing the dye biosorption by dried sugar beet pulp in the concentration (100-800 mg l{sup -1}) and temperature (25-45 deg. C) ranges studied. Simple mass transfer and kinetic models were applied to the experimental data to examine the mechanisms of biosorption and potential rate controlling steps such as external mass transfer, intraparticle diffusion and biosorption process. The sorption process was found to be controlled by both surface and pore diffusion with surface diffusion at the earlier stages followed by pore diffusion at the later stages. Pseudo first-order, pseudo second-order and saturation type kinetic models described the biosorption kinetics accurately at all concentrations and temperatures studied. The thermodynamic analysis indicated that the sorption process was exothermic and the biosorption of dye on dried sugar beet pulp might be physical in nature.

    Rieppo, K. [Metsaeteho, Helsinki (Finland); Hakkila, P. [Finnish Forest Research Inst., Vantaa (Finland); Aho, V.J. [VTT Energy, Jyvaeskylae (Finland)


    The objective of the research was to develop a procurement method for small-diameter pulpwood based on chain-flail delimbing-debarking method. The study consisted of four parts: Development of the chain-flail delimbing-debarking method (based on Peterson Pacific DDC 5000 device); Combined chain-flail delimbing and drum-debarking; Processing and procurement of the chain-flail delimbing chips and; Intensifying of the timber debarking in chain-flail delimbing. The project was coordinated by Metsaeteho, and it was carried out as cooperation between Metsaeteho, the Finnish Forest Research Institute (METLA), VTT Energy, Pertti Szepaniak Oy and Enso-Gutzeit Oy. A calculation model, by which it is possible to determine the costs of pulpwood chips and fuel-rawmaterials formed beside the pulpwood chips while using different kinds of procurement methods and chains, was developed for chain-flail delimbing-debarking-chipping method based on utilization of Peterson Pacific device. By the model it is possible to optimize the utilization of the method in practice. A new fixed version of the combined chain-flail delimbing drum-debarking equipment was constructed in 1995. Tests with this equipment started in February 1996. A debarking simulator, by which it is possible to study the effects of the lengths of the chains and brushes, the positioning, the hit-angles and speeds on the removal of branches and bark, has been compiled in the `Intensification of wood debarking in chain-flail delimbing` sub-task. Preliminary tests have been made using mainly frozen first thinning pine as test material

  19. Treatment of full thickness cartilage defects in human knees with Autologous Chondrocyte Transplantation

    Khalilallah Nazem


    Full Text Available Background: Although a variety of strategies have been employed for managing articular cartilage defects in the knee, overall outcomes have not been satisfactory. An alternative option may be autologous chondrocyte transplantation (ACT. However, as this method is still under investigation, here we assessed the efficacy of ACT for human knee defect cartilage repair. Methods: In a randomized clinical trial study, eleven patients (mean age 31.09 years were enrolled in the study with full thickness cartilage defects in the knee. Arthroscopically, healthy cartilage was obtained, chondrocytes expanded for 2-3 weeks and ACT performed. Clinical status was evaluated before ACT, 6 and 12 months after ACT using the Brittberg-Peterson functional assessment and modified Cincinnati rating score. Magnetic resonance imaging (MRI findings were evaluated based on the scoring systems used by Sally Roberts and by Henderson. Results: Modified Cincinnati rating indicated significant improvement of clinical score before ACT compared to 6 (p = 0.000 and 12 (p = 0.000 months after ACT (from 2.73 before ACT to 7.27, 8.36 and 9.5 at 6, 12, and 48 months after ACT, respectively. Brittberg-Peterson functional assessment indicated a decline from 79.27 to 25.82 and 19.27 at 6 and 12 months post ACT. Further, statistical test demonstrated significant differences 6, 12 and 48 months post ACT (p = 0.007. Evaluation of MRI revealed a score of 6.5 for Henderson criteria and a score of 2.5 for Robert criteria. Conclusions: Our study demonstrated that ACT of the knee provides an excellent treatment for full thickness cartilage defects with outstanding clinical and radiological outcomes.

  20. Background Noise of the Aldeia da Serra Region (Portugal) from a temporary broad band network (United States)

    Wachilala, Piedade; Borges, José; Caldeira, Bento; Bezzeghoud, Mourad


    In this study, we analyse seismic background noise to assess the effect of noise based on the detectability of a temporary network constituted by DOCTAR (Deep Ocean Test Array), who have been deployed in a period between 2011 and 2012 in Portugal mainland, and the Évora permanent seismic station. This network is constituted by 14 digital broadband stations (14 CMG-3ESP and one STS2 sensors) with a flat response between the 60 sec to 50 Hz, 24-bit and 120s to 60Hz respectively. The temporary network was operated in continuous recording mode (three-components) in a region located in the north of the region of Évora, within a radius of about 30 km around the village of Aldeia da Serra, region in which there is an important seismic activity in the context of Portugal mainland. We calculated power spectral densities of background noise for each station/component and compare them with high-noise model and low-noise model of Peterson (1993). We consider different for day and night local and for different periods of the year. Power spectral density estimates show moderate noise levels with all stations falling within the high and low bounds of Peterson (1993). Considering the results of the noise, we estimate the detection limit of each station and consequently the detectability of the network. From this information and taking in attention the events recorded during the period of DOCTAR operation we analyse the improvement promoted by this temporary network regarding the existent seismic networks to the local seismicity study. This work was partially supported by COMPETE 2020 program (POCI-01-0145-FEDER-007690 project). We acknowledge GFZ Potsdam for providing part of the data used in this study.

  1. Character Strengths Profiles of Musicians and Non-Musicians

    Directory of Open Access Journals (Sweden)

    Angelika Güsewell


    Full Text Available In the 1980s and 1990s a series of studies investigated musicians’ personalities using Cattell’s 16 personality factors, Eysenck’s PEN super factors, and Costa and McCrae’s Big Five. The findings hinted at some traits most musicians seemed to share, and highlighted differences between the personality traits of brass and string players. However, results were inconclusive and sometimes contradictory. The main aim of this study was to further investigate the topic using novel theoretical frameworks: Peterson and Seligman’s (2004 VIA classification, and Güsewell and Ruch’s (2012 responsiveness to the beautiful and good model. The character strengths and responsiveness to the beautiful and good profiles of classical and non-classical (i.e. jazz, rock, and pop professional musicians, amateur musicians, and non-musicians were compared. In total, 324 participants equally distributed among these three subgroups completed the Values in Action Inventory of Strengths (VIA-IS; Peterson, Park, & Seligman, 2005, the Engagement with Beauty Scale (EBS; Diessner, Solom, Frost, Parsons, & Davidson, 2008, and the Appreciation of Beauty and Excellence Test (ABET; Güsewell & Ruch, 2012. Professional musicians scored significantly higher than non-musicians on self-regulation, appreciation of beauty and excellence, and responsiveness to artistic beauty; they scored significantly lower than amateurs on judgement and perspective, and lower than both amateurs and non-musicians on teamwork, fairness, and leadership. Professional classical musicians scored significantly higher than professional non-classical musicians on prudence. The latter, in turn, displayed significantly higher scores on creativity, bravery, and honesty. The two groups did not differ with respect to any of the responsiveness dimensions.

  2. Avaliação da depressão e de testes neuropsicológicos em pacientes com desordens temporomandibulares Depression and neuropsychological testing in patients with temporomandibular disorders

    Directory of Open Access Journals (Sweden)

    Caio Selaimen


    Full Text Available A fim de determinar se existem diferenças neuropsicológicas entre os grupos, o Teste de Aprendizado Verbal da Califórnia (CVLT e o Teste do Trigrama de Consoantes de Brown-Peterson (CCC foram usados. A depressão foi avaliada pelo Inventário de Depressão de Beck (BDI. Os testes neuropsicológicos usados não mostraram diferenças estatisticamente significativas entre os três grupos estudados, o que pode ser devido à baixa proporção de pacientes com educação pós-secundária (25%. Entretanto, o grupo experimental (Grupos I e II mostrou índices de depressão mais elevados (pA cross-sectional retrospective study was undertaken, with the primary objective of discovering if there were any neuropsychological differences among and within groups. The California Verbal Learning Test (CVLT and the Brown-Peterson Consonant Trigram Auditory Memory Test (CCC were used. Depression was assessed by the Beck Depression Inventory (BDI - Portuguese Version.The neuropsychological tests used did not present any statistically significant differences among the three groups studied, which might be due to the low proportion of patients with post high school education (20%. However, the experimental group (Groups I plus II showed higher scores on depression (p<0.05 than Group III. In addition, Group II showed higher levels of depression (p<0.01 than Group I, and no statistical differences were found between Group I and III. Taken together, these results suggest that memory tests are highly dependent on the education levels of the participants and cannot be widely used. Additionally, depression plays a role not only in the etiology, but also in the perpetuation of TMD.

  3. Removal of norfloxacin in deionized, municipal water and urine using rice (Oryza sativa) and coffee (Coffea arabica) husk wastes as natural adsorbents. (United States)

    Paredes-Laverde, Marcela; Silva-Agredo, Javier; Torres-Palma, Ricardo A


    The removal of the widely used antibiotic norfloxacin (NOR), the presence of which has been reported in natural water, was evaluated using rice (RH) and coffee (CH) husk wastes as adsorbents. Low particle sizes and natural pH in distilled water favored NOR elimination in both materials. In order to investigate the type of adsorption, the data was adjusted to the Langmuir, Freundlich and Redlich-Peterson isotherms. The best fit for the Langmuir and Redlich-Peterson isotherms suggested a monolayer-type adsorption model. Kinetic models of pseudo first and second order were also evaluated, the latter being the most suitable to represent the NOR adsorption phenomenon. Meanwhile, the intraparticle diffusion model indicated that the adsorption of NOR occurs both at the surface and within the pores of the material. Studies performed on thermodynamic aspects such as activation energy (E a ), enthalpy change (ΔH˚) and Gibbs free energy change (ΔG˚) suggest that the physisorption of the pollutant takes place through a spontaneous endothermic process. Additionally, PZC determination, Boehm method, chemical composition, thermodynamic analysis, and FTIR spectra before and after the adsorption of the antibiotic suggest that in CH adsorbents this occurred mainly through electrostatic interactions, while in RH hydrogen bonds also contributed significantly. Finally, the efficiency of natural adsorbents for the removal of NOR was evaluated in synthetic matrices of municipal wastewater and urine, and promising results were obtained despite the complexity of these matrices. The results presented in this work show the potential application of RH and CH residues as a low-cost alternative for the removal of NOR even in complex matrices. However, despite the similarities between the materials, CH waste showed better properties for the removal of the tested NOR due to its higher surface area, lower PZC and higher number of acid groups.

  4. The use of arthroscopic thermal shrinkage to treat chronic lateral ankle instability in young athletes. (United States)

    Maiotti, Marco; Massoni, Carlo; Tarantino, Umberto


    The aim of this study was to evaluate the preliminary results of arthroscopic thermal capsular shrinkage performed for chronic lateral ankle instability in soccer players. Case series. We reviewed 22 male soccer players (average age, 18 years) with chronic lateral ankle instability who underwent arthroscopic thermal shrinkage between 1997 and 1998. The only exclusion criterion for this study was the failure of previous surgery. Before surgery, all patients had participated in a physical rehabilitation program consisting of peroneal strengthening exercises and proprioceptive training for several months, without any relief of their symptoms. All patients were characterized by repeated episodes of giving way, a positive anterior drawer sign, and positive stress radiographs. The stress radiographs consisted of a sagittal stress and talar tilt by the TELOS device (Fallston, MD). The Karlsson and Peterson ankle function scoring scale was used to assess these patients for their current activity level as well as activity before surgery. Patients were reviewed at a mean of 42 months (range, 32 to 56 months); 19 patients (86.3%) reported a good or excellent functional outcome as assessed by the Karlsson and Peterson ankle function scoring scale. Eighteen of the 22 patients presented no evidence of ankle instability on physical examination or on stress radiographs. Only 1 patient was not able to return to his previous level of sports activity and complained of ankle instability when walking on uneven ground. This study suggests that arthroscopic thermal capsular shrinkage is a valid and safe procedure for treatment of chronic lateral ankle instability. Longer follow-up is needed, however, to see how these results may change with time in high-demand athletes. Level IV.

  5. Pentachlorophenol sorption in nylon fiber and removal by immobilized Rhizopus oryzae ENHE. (United States)

    León-Santiestebán, Hugo; Meraz, Mónica; Wrobel, Kazimierz; Tomasini, Araceli


    This study describes pentachlophenol (PCP) sorption in nylon fiber in which Rhizopus oryzae ENHE was immobilized to remove the chemical compound. The experimental sorption data were analyzed using the Langmuir, Freundlich, and Redlich-Peterson isotherm models using non-linear error functions to fit the experimental data to the three models. Results showed that the isotherm obtained from the data fitted the three models used. However, the g parameter from Redlich-Peterson model showed that the isotherm obtained approaches the Freundlich model. This support reached the sorption equilibrium concentration at 3mg PCPg(-1)nylon. To study PCP removal capability by R. oryzae ENHE and to eliminate the error caused by PCP sorbed by the nylon fiber during its quantification, nylon fiber at PCP equilibrium sorption concentration was used to immobilize R. oryzae ENHE. It was found that this fungus grew within nylon fiber cubes in presence or not of PCP, even when PCP caused growth inhibition. Maximum biomass accumulated into nylon cubes without PCP was of 32 mg biomass g(-1)nylon and into nylon cubes at PCP equilibrium concentration was of 18 mg g(-1)nylon. The results showed that R. oryzae ENHE immobilized into nylon fiber removed 88.6% and 92% of PCP in cultures with 12.5 and 25 mg PCPL(-1), as initial concentration, respectively. This is the first work to report that a zygomycete, such as R. oryzae ENHE, immobilized into nylon fiber kept its potential to remove PCP. Copyright © 2011 Elsevier B.V. All rights reserved.

  6. Kinetic and Equilibrium Studies of Sorption of Ammonium in the Soil-Water Environment in Agricultural Areas of Central Poland

    Directory of Open Access Journals (Sweden)

    Anna Sieczka


    Full Text Available Sorption characteristics of nitrogen compounds is necessary in ascertaining their fate in the soil-water environment. This paper presents a laboratory “batch” experiment for determining the sorption parameters of ammonium in the soil-water environment. Three agricultural soils (silt loam, loam, and sand with different contents of the clay fraction, significantly affecting the range of the adsorption of contaminants on the surface of solid particles, were chosen as research material. Considering the composition of ammonium nitrate (a commonly used fertilizer in Poland, ammonium solutions with a concentration of 0–52 mg NH4+/L were used as markers. Pseudo-first order, pseudo-second order, and intra-particle diffusion kinetic models were used to describe the mechanisms of ammonium adsorption. Experimental data obtained from the equilibrium tests have been analysed using two-parameter (Freundlich, Langmuir, Temkin and three-parameter (Redlich-Peterson, Hill, Sips models. In order to adjust the parameters of the considered isotherms to the experimental data, the method of minimization of the sum of squared errors was used. Additionally, the maximum sorption capacities and reduction ratios of ammonium versus time were assessed. It was observed that the presence of silt loam and loam in the soil profile can increase the possibility of ammonium adsorption up to almost 20%. Taking into consideration the results of the batch tests, it was concluded that ammonium adsorption attains equilibrium within 48 h. Experimental data was best followed by the pseudo-second order equation and the adsorption isotherm conformed to the Redlich-Peterson model for loam and sand.

    A new adsorbent system for removing methylene blue (MB) from aqueous solutions has been investigated. This new adsorbent is cereal chaff, an agriculture product in middle-west region in China. Variables of the system, including biosorption time, chaff dose, pH, salt concentration and initial MB concentration, were adopted to study their effects on MB removal. The results showed that as the dose of chaff increased, the percentage of MB sorption increased accordingly. There was no significant difference in the dye concentration remaining when the pH was increased from 4.0 to 11.0. The salt concentration has negative effect on MB removal. At the experimental range of MB concentration, the amount of MB adsorbed onto per unit mass of chaff (q e ) is direct ratio to MB initial concentration (c 0 ). The equilibrium data were analyzed using five equilibrium models, the Langmuir, the Freundlich, the Redlich-Peterson, the Koble-Corrigan and the Temkin isotherms. The results of non-linear regressive analysis are that the isotherms of Langmuir, Redlich-Peterson and Koble-Corrigan are better fit than the isotherms of Freundlich and Temkin at different temperatures according to the values of determined coefficients (R 2 ) and Chi-square statistic (χ 2 ). The maximum equilibrium capacities of chaff from Langmuir models are 20.3, 25.3 and 26.3 mg g -1 at 298, 318 and 333 K, respectively. Using the equilibrium concentration constants obtained at different temperatures, various thermodynamic parameters, such as ΔG 0 , ΔH 0 and ΔS 0 , have been calculated. The thermodynamics parameters of MB/chaff system indicate spontaneous and endothermic process. It was concluded that an increase in temperature results in a bigger MB loading per unit weight of the chaff

  8. Separating Pumping and Other Influences on Groundwater Head Variation (United States)

    Shapoori, V.; Western, A. W.; Peterson, T. J.; Costelloe, J.


    The dynamics of unconfined groundwater levels are usually the result of numerous and interacting factors, such as land cover change, climate variability and groundwater pumping. Estimating the impact from pumping is highly significant for resource management but also very challenging. A variety of methods are used to model water-table dynamics influenced by pumping, ranging from spatially explicit, numerical models to stochastic approaches. Transfer function noise (TFN) modelling can be used to model the dynamic behaviour of a wide range of hydrologic variables, including time series of groundwater head. Recently, TFN models have been developed to better link water table dynamics with different types of individual stresses, including pumping (Von Asmuth et al. 2002). Peterson & Western (2011) advanced the transfer function noise model of Von Asmuth et al. (2002) to account for non-linear hydrological processes by inclusion of a parsimonious vertically lumped soil moisture storage(SMS). Shapoori et al. (2011) proposed an improved time series formulation for estimation of the impacts of pumping. That study undertook a synthetic assessment of the ability of a range of time series models to represent the impacts of pumping by applying them to groundwater head time series from a synthetic aquifer. This paper further expands the Shapoori at al. (2011) time series method for quantifying the impact of groundwater pumping within unconfined sedimentary aquifers by applying it to real data and by taking account of a surface water body. The study area is the Clydebank groundwater subregion located in Victoria Australia. Nine salinity control pumping bores are used in some of the worst salinity areas to lower the groundwater table and consequently reduce soil salinity. The method has been applied to 43 observation bores and the results show that the model has good predictive performance with mean and minimum coefficient efficiency values of 0.7 and 0.5 respectively.

  9. Correlation consistent basis sets for actinides. II. The atoms Ac and Np-Lr (United States)

    Feng, Rulin; Peterson, Kirk A.


    New correlation consistent basis sets optimized using the all-electron third-order Douglas-Kroll-Hess (DKH3) scalar relativistic Hamiltonian are reported for the actinide elements Ac and Np through Lr. These complete the series of sets reported previously for Th-U [K. A. Peterson, J. Chem. Phys. 142, 074105 (2015); M. Vasiliu et al., J. Phys. Chem. A 119, 11422 (2015)]. The new sets range in size from double- to quadruple-zeta and encompass both those optimized for valence (6s6p5f7s6d) and outer-core electron correlations (valence + 5s5p5d). The final sets have been contracted for both the DKH3 and eXact 2-component (X2C) Hamiltonians, yielding cc-pVnZ-DK3/cc-pVnZ-X2C sets for valence correlation and cc-pwCVnZ-DK3/cc-pwCVnZ-X2C sets for outer-core correlation (n = D, T, Q in each case). In order to test the effectiveness of the new basis sets, both atomic and molecular benchmark calculations have been carried out. In the first case, the first three atomic ionization potentials (IPs) of all the actinide elements Ac-Lr have been calculated using the Feller-Peterson-Dixon (FPD) composite approach, primarily with the multireference configuration interaction (MRCI) method. Excellent convergence towards the respective complete basis set (CBS) limits is achieved with the new sets, leading to good agreement with experiment, where these exist, after accurately accounting for spin-orbit effects using the 4-component Dirac-Hartree-Fock method. For a molecular test, the IP and atomization energy (AE) of PuO2 have been calculated also using the FPD method but using a coupled cluster approach with spin-orbit coupling accounted for using the 4-component MRCI. The present calculations yield an IP0 for PuO2 of 159.8 kcal/mol, which is in excellent agreement with the experimental electron transfer bracketing value of 162 ± 3 kcal/mol. Likewise, the calculated 0 K AE of 305.6 kcal/mol is in very good agreement with the currently accepted experimental value of 303.1 ± 5 kcal

  11. Utrecht Radiative Transfer Courses (United States)

    Rutten, R. J.


    The Utrecht course ``The Generation and Transport of Radiation'' teaches basic radiative transfer to second-year students. It is a much-expanded version of the first chapter of Rybicki & Lightman's ``Radiative Processes in Astrophysics''. After this course, students understand why intensity is measured per steradian, have an Eddington-Barbier feel for optically thick line formation, and know that scattering upsets LTE. The text is a computer-aided translation by Ruth Peterson of my 1992 Dutch-language course. My aim is to rewrite this course in non-computer English and make it web-available at some time. In the meantime, copies of the Peterson translation are made yearly at Uppsala -- ask them, not me. Eventually it should become a textbook. The Utrecht course ``Radiative Transfer in Stellar Atmospheres'' is a 30-hour course for third-year students. It treats NLTE line formation in plane-parallel stellar atmospheres at a level intermediate between the books by Novotny and Boehm-Vitense, and Mihalas' ``Stellar Atmospheres''. After this course, students appreciate that epsilon is small, that radiation can heat or cool, and that computers have changed the field. This course is web-available since 1995 and is regularly improved -- but remains incomplete. Eventually it should become a textbook. The three Utrecht exercise sets ``Stellar Spectra A: Basic Line Formation'', ``Stellar Spectra B: LTE Line Formation'', and ``Stellar Spectra C: NLTE Line Formation'' are IDL-based computer exercises for first-year, second-year, and third-year students, respectively. They treat spectral classification, Saha-Boltzmann population statistics, the curve of growth, the FAL-C solar atmosphere model, the role of H-minus in the solar continuum, LTE formation of Fraunhofer lines, inversion tactics, the Feautrier method, classical lambda iteration, and ALI computation. The first two sets are web-available since 1998; the third will follow. Acknowledgement. Both courses owe much to previous

  12. Adsorption studies of methylene blue and phenol onto vetiver roots activated carbon prepared by chemical activation. (United States)

    Altenor, Sandro; Carene, Betty; Emmanuel, Evens; Lambert, Jacques; Ehrhardt, Jean-Jacques; Gaspard, Sarra


    Vetiver roots have been utilized for the preparation of activated carbon (AC) by chemical activation with different impregnation ratios of phosphoric acid, X(P) (gH(3)PO(4)/g precursor): 0.5:1; 1:1 and 1.5:1. Textural characterization, determined by nitrogen adsorption at 77K shows that mixed microporous and mesoporous structures activated carbons (ACs) with high surface area (>1000 m(2)/g) and high pore volume (up to 1.19 cm(3)/g) can be obtained. The surface chemical properties of these ACs were investigated by X-ray photoelectron spectroscopy (XPS) and Boehm titration. Their textural and chemical characteristics were compared to those of an AC sample obtained by steam activation of vetiver roots. Classical molecules used for characterizing liquid phase adsorption, phenol and methylene blue (MB), were used. Adsorption kinetics of MB and phenol have been studied using commonly used kinetic models, i.e., the pseudo-first-order model, the pseudo-second-order model, the intraparticle diffusion model and as well the fractal, BWS (Brouers, Weron and Sotolongo) kinetic equation. The correlation coefficients (R(2)) and the normalized standard deviation Deltaq (%) were determined showing globally, that the recently derived fractal kinetic equation could best describe the adsorption kinetics for the adsorbates tested here, indicating a complex adsorption mechanism. The experimental adsorption isotherms of these molecules on the activated carbon were as well analysed using four isotherms: the classical Freundlich, Langmuir, Redlich-Peterson equations, but as well the newly published deformed Weibull Brouers-Sotolongo isotherm. The results obtained from the application of the equations show that the best fits were achieved with the Brouers-Sotolongo equation and with the Redlich-Peterson equation. Influence of surface functional groups towards MB adsorption is as well studied using various ACs prepared from vetiver roots and sugar cane bagasse. Opposite effects governing MB

  13. Modular invariant representations of infinite-dimensional Lie algebras and superalgebras. (United States)

    Kac, V G; Wakimoto, M


    In this paper, we launch a program to describe and classify modular invariant representations of infinite-dimensional Lie algebras and superalgebras. We prove a character formula for a large class of highest weight representations L(lambda) of a Kac-Moody algebra [unk] with a symmetrizable Cartan matrix, generalizing the Weyl-Kac character formula [Kac, V. G. (1974) Funct. Anal. Appl. 8, 68-70]. In the case of an affine [unk], this class includes modular invariant representations of arbitrary rational level m = t/u, where t [unk] Z and u [unk] N are relatively prime and m + g >/= g/u (g is the dual Coxeter number). We write the characters of these representations in terms of theta functions and calculate their asymptotics, generalizing the results of Kac and Peterson [Kac, V. G. & Peterson, D. H. (1984) Adv. Math. 53, 125-264] and of Kac and Wakimoto [Kac, V. G. & Wakimoto, M. (1988) Adv. Math. 70, 156-234] for the u = 1 (integrable) case. We work out in detail the case [unk] = A(1) ((1)), in particular classifying all its modular invariant representations. Furthermore, we show that the modular invariant representations of the Virasoro algebra Vir are precisely the "minimal series" of Belavin et al. [Belavin, A. A., Polyakov, A. M. & Zamolodchikov, A. B. (1984) Nucl. Phys. B 241, 333-380] using the character formulas of Feigin and Fuchs [Feigin, B. L. & Fuchs, D. B. (1984) Lect. Notes Math. 1060, 230-245]. We show that tensoring the basic representation and modular invariant representations of A(1) ((1)) produces all modular invariant representations of Vir generalizing the results of Goddard et al. [Goddard P., Kent, A. & Olive, D. (1986) Commun. Math. Phys. 103, 105-119] and of Kac and Wakimoto [Kac, V. G. & Wakimoto, M. (1986) Lect. Notes Phys. 261, 345-371] in the unitary case. We study the general branching functions as well. All these results are generalized to the Kac-Moody superalgebras introduced by Kac [Kac, V. G. (1978) Adv. Math. 30, 85-136] and to N

    Alagumuthu G.


    Full Text Available This study deals the application of Cynodon dactylon based thermally activated carbon for fluoride toxicity. The batch adsorption techniques was followed at neutral pH as the functions of contact time, adsorbent dose, adsorbate concentration, temperature and the effect of co-anions. The data indicate that the prepared adsorbent surface sites are heterogeneous in nature and that fits into a heterogeneous site-binding model. The present system followed the Redlich-Peterson isotherm as well as Langmuir adsorption isotherm model. Lagergren pseudo-first-order, pseudo-second-order, intra particle diffusion and Elovich kinetics were modeled to describe the adsorption rate of fluoride and determined as this scheme followed pseudo-second-order kinetics. The calculated enthalpy change, ΔH°, and entropy change, ΔS°, for the adsorption process are +8.725 kJ/mol and +0.033 J/mol K respectively and shows endothermic experience. Instrumental analysis of XRD, FTIR and SEM gives the idea about the fluoride binding ability of adsorbent.

    A. Edwin Vasu


    Full Text Available Activated carbon prepared from tamarind fruit shells by direct carbonization was used for the removal of rhodamine B and malachite green dyes from aqueous solutions. Adsorption studies were performed by varying such parameters as dye concentration, pH of the dye solution, time and temperature. The equilibrium adsorption data obtained were used to calculate the Freundlich, Langmuir and Redlich-Peterson isotherm parameters. Increase in pH of the solution pH resulted in increased adsorption of both the dyes. Kinetic studies indicate that the pseudo-second order model can be used for describing the dynamics of the sorption processes. Film diffusion of the dyes was the rate determining step at low dye concentrations while diffusion of dyes through the pores the carbon particles determined the overall uptake at high concentrations. Thermodynamic parameters of the endothermic sorptions were evaluated using van’t Hoff equation. Desorption studies with acids were also performed in order to regenerate the used carbons.

    Alejandro C. Cosentino


    Full Text Available The study of individual differences in positive characteristics has mainly focused on moral traits. The objectives of this research were to study individual differences in positive characteristics from the point of view of the layperson, including non-moral individual characteristics, and to generate a replicable model of positive factors. Three studies based on a lexical approach were conducted. The first study generated a corpus of words which resulted in a refined list of socially shared positive characteristics. The second study produced a five-factor model of positive characteristics: erudition, peace, cheerfulness, honesty, and tenacity. The third study confirmed the model with a different sample. The five-positive-factor model not only showed positive associations with emotional, psychological and social well-being, but it also accounted for the variance beyond that accounted for by the Big Five factors in predicting these well-being dimensions. In addition, the presence of convergent and divergent validity of the five positive factors is shown with relation to the Values-in-Action (VIA classification of character strengths proposed by Peterson and Seligman (2004.

  19. Perceived control and voice handicap in patients with voice disorders. (United States)

    Frazier, Patricia; Merians, Addie; Misono, Stephanie


    The purpose of the study was to replicate and extend previous research on the relation between perceived present control and voice handicap and to further examine the psychometric properties of a present control scale adapted for patients with voice disorders (Misono, Meredith, Peterson, & Frazier, 2016). Sample 1 consisted of 1,129 patients recruited from a voice disorder clinic who completed measures of perceived present control, distress, and voice handicap in the clinic. Sample 2 consisted of 62 patients from the same clinic who completed measures of present control, distress, voice handicap, and general control beliefs online at baseline and measures of present control and voice handicap again 3 weeks later (n = 59). With regard to the psychometric properties of the voice-adapted present control scale, alpha coefficients were above .80 and the 3-week test-reliability coefficient was .69. There was mixed support for the hypothesized 1-factor structure of the scale. In Sample 1, present control was more strongly associated with lower voice handicap than was distress and accounted for significant variance in voice handicap controlling for distress. In Sample 2, present control at baseline predicted later voice handicap, controlling for general control beliefs and distress. Present control appears to be a promising target for adjunctive interventions for patients with voice disorders. An evidence-based online present control intervention (Hintz, Frazier, & Meredith, 2015) is being adapted for this patient population. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  20. Using Beta Coefficients to Impute Missing Correlations in Meta-Analysis Research: Reasons for Caution. (United States)

    Roth, Philip L; Le, Huy; Oh, In-Sue; Van Iddekinge, Chad H; Bobko, Philip


    Meta-analysis has become a well-accepted method for synthesizing empirical research about a given phenomenon. Many meta-analyses focus on synthesizing correlations across primary studies, but some primary studies do not report correlations. Peterson and Brown (2005) suggested that researchers could use standardized regression weights (i.e., beta coefficients) to impute missing correlations. Indeed, their beta estimation procedures (BEPs) have been used in meta-analyses in a wide variety of fields. In this study, the authors evaluated the accuracy of BEPs in meta-analysis. We first examined how use of BEPs might affect results from a published meta-analysis. We then developed a series of Monte Carlo simulations that systematically compared the use of existing correlations (that were not missing) to data sets that incorporated BEPs (that impute missing correlations from corresponding beta coefficients). These simulations estimated ρ̄ (mean population correlation) and SDρ (true standard deviation) across a variety of meta-analytic conditions. Results from both the existing meta-analysis and the Monte Carlo simulations revealed that BEPs were associated with potentially large biases when estimating ρ̄ and even larger biases when estimating SDρ. Using only existing correlations often substantially outperformed use of BEPs and virtually never performed worse than BEPs. Overall, the authors urge a return to the standard practice of using only existing correlations in meta-analysis. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    Full Text Available The Orientations to Happiness Questionnaire (OTH; Peterson, Park in Seligman, 2005 measures three routes to happiness: life of pleasure (hedonism, life of meaning (eudemonia and life of engagement (flow. The questionnaire was adapted to Slovene in several steps (two independent translations by experts, reaching agreement, retranslation; modification and its psychometric properties were examined with 1064 participants, aged 18 to 91 years. The participants also rated their satisfaction with life. Confirmatory factor analysis indicated adequate fit of the expected three-factor model. Results showed satisfactory internal consistency of the three scales (alpha coefficients ranged from 0.70 to 0.83 and satisfactory itemtotal correlations. Inter-correlation coefficients suggested low associations between orientation to pleasure and orientation to meaning, while orientation to engagement was moderately related to the other two orientations to happiness. Men and women did not differ statistically significantly in their self-reported orientations to happiness, while age of the participants had a significant, though small negative effect on orientation to pleasure. After accounting for demographic characteristics orientations to pleasure and engagement significantly improved the prediction of subjective life satisfaction. Results also indicate that satisfaction with life was highest in participants relatively high on all three orientations to happiness.

  3. Glutaraldehyde cross-linked magnetic chitosan nanocomposites: Reduction precipitation synthesis, characterization, and application for removal of hazardous textile dyes. (United States)

    Kadam, Avinash A; Lee, Dae Sung


    Magnetic chitosan nanocomposites (MCNCs) were synthesized by an inexpensive reduction precipitation technique using a glutaraldehyde cross-linking agent at room temperature. Successful chitosan coating of iron oxide nanoparticles was confirmed by X-ray photoemission spectroscopy. X-ray diffraction data revealed crystalline particle sizes for the iron oxide and MCNCs to be around 6-7 and 8-9 nm, respectively. In addition, the MCNCs exhibited supermagnetic properties having magnetic saturation of 17.5 emu/g. The synthesized MCNCs showed 91.60% absorption of Acid Red 2, while iron oxide 16.40% absorption; enhanced performance in MCNCs was resulted from presence of free amino and hydroxyl groups. Furthermore, the optimum pH and adsorbent concentration were 3 and 1.0 g/L, respectively. The Redlich-Peterson isotherm fit experimental data better than Langmuir and Freundlich models, based on non-linear regression. Finally, MCNCs showed 96% American Dye Manufacturing Institute (ADMI) value removal and gave recovery efficiency of 100%, making them attractive for further practical applications.

  4. The characteristics of seismological data from offshore observatory in the northeastern South Korea (United States)

    Cho, H. M.; Kim, G.; Che, I. Y.; Lim, I. S.; Kim, Y.; Shin, I. C.


    The real-time seismic observation in the ocean is challenging but provides unprecedented data appropriate for seismological research in the ocean from local to global scale. The offshore seismic observatory in the northeastern South Korea operated by Korea Institute of Geoscience and Mineral Resources (KIGAM) integrates the seismic, hydro-acoustic, and infrasound data and transmits the integrated data with oceanographic sensing and SOH (State of Health) to KIGAM in real-time. The observatory is equipped with ocean bottom broadband seismometer (120 s - 50 Hz) laid on the sea-floor approximately 80 meters below sea level. This study focuses on the properties of the data from the sea-floor, noise level evaluation of the observatory in the shallow water, and assessing event detection threshold of the offshore site. We computes the power spectral density (PSD) to describe the background seismic noise and its variations with seasonal change and meteorological condition. The seismic noise probability density functions from the PSDs shows that broadband seismic noise is generally high compared with the Peterson's NLNM and NHNM model. The statistical analysis of the seismic noise is given. We compares the noise level with that of the nearby onshore broadband seismometer. The quality of waveform data from the local, regional, and teleseismic earthquake are evaluated and compared with corresponding onshore data. The S-wave amplification is prominent on the sea-floor observations from local earthquake. The detection threshold on the local earthquake is estimated.

  5. Are only Emotional Strengths Emotional? Character Strengths and Disposition to Positive Emotions. (United States)

    Güsewell, Angelika; Ruch, Willibald


    This study aimed to examine the relations between character strengths and dispositional positive emotions (i.e. joy, contentment, pride, love, compassion, amusement, and awe). A sample of 574 German-speaking adults filled in the Dispositional Positive Emotion Scales (DPES; Shiota, Keltner, & John, 2006), and the Values in Action Inventory of Strengths (VIA-IS; Peterson, Park, & Seligman, 2005). The factorial structure of the DPES was examined on item level. Joy and contentment could not be clearly separated; the items of the other five emotions loaded on separate factors. A confirmatory factor analysis assuming two latent factors (self-oriented and object/situation specific) was computed on scale level. Results confirmed the existence of these factors, but also indicated that the seven emotions did not split up into two clearly separable families. Correlations between dispositional positive emotions and character strengths were positive and generally low to moderate; a few theoretically meaningful strengths-emotions pairs yielded coefficients>.40. Finally, the link between five character strengths factors (i.e. emotional strengths, interpersonal strengths, strengths of restraint, intellectual strengths, and theological strengths) and the emotional dispositions was examined. Each of the factors displayed a distinctive "emotional pattern"; emotional strengths evidenced the most numerous and strongest links to emotional dispositions. © 2012 The Authors.

    Full Text Available A narrative of church life today. We live in a time when survival seems to be the biggest concern of most mainline congregations and denominations. How can the church possibly survive? This is a question that is asked in almost every corner of the institution. Since the 1960s, numerous books and articles have been published, trying to get a handle on why the mainline churches are in decline. Whatever the cause may be, decline is causing great fear and anxiety in the mainline churches. In an effort to answer the underlying question: ‘What shall we do to turn the situation around?’, some churches are simply trying to ‘market’ themselves and their message. Others try to ’do’ church differently. Some try to rediscover the purpose of the church, et cetera. Cheryl Peterson argues that churches are, in fact, facing an ecclesial crisis, that is much more than a crisis of declining numbers and membership. There is a deeper and more basic issue that must be explored, one that has to do with the church’s theological identity, and that is: what it means to be church? This article is about the question: Who is the church? And it answers the question on the basis of Peterson’s thesis by means of a narrative of the church that commences with the Spirit.

  7. Synthesis and characterization of poly[1-(N,N-bis-carboxymethyl)amino-3-allylglycerol-co-dimethylacrylamide] grafted to magnetic nano-particles for extraction and determination of letrozole in biological and pharmaceutical samples. (United States)

    Ahmad Panahi, Homayon; Soltani, Elham Reza; Moniri, Elham; Tamadon, Atefeh


    In this paper, a new method is reported for the surface grafting of poly[1-(N,N-bis-carboxymethyl)amino-3-allylglycerol-co-dimethylacrylamide] onto magnetic nano-particles modified by 3-mercaptopropyltrimethoxysilane. The grafted nano-sorbent was characterized by Fourier transform infrared spectroscopy, elemental analysis, thermogravimetric analysis, and scanning electron microscopy. Agglomerated nano-particles with multi-pores were used for extraction and determination of trace letrozole in human biological fluids and pharmaceutical samples. The profile of the letrozole uptake by the magnetic nano-sorbent reflected good accessibility of the active sites in the grafted polymer. Scatchard analysis revealed that the sorption capacity of the functionalized nano-sorbent was 6.27 µmol g(-1) at an optimum pH of 4. The equilibrium adsorption data of letrozole by grafted magnetic nano-sorbent were analyzed by Langmuir, Freundlich, Temkin and Redlich-Peterson models. Conformation of the experimental data in the Langmuir isotherm model indicated the homogeneous binding site of functional polymer-grafted magnetic nano-sorbent surface. Nearly 89% of letrozole was released in simulated gastric fluid, pH 1.2, in 2h and 79% in simulated intestinal fluid, pH 7.4, in 30 h. These results show the utility of the letrozole loaded- polymer grafted magnetite nano-particles for enteric drug delivery. © 2013 Elsevier B.V. All rights reserved.

  9. A unified model of combined energy systems with different cycle modes and its optimum performance characteristics

    International Nuclear Information System (INIS)

    Zhang Yue; Hu, Weiqiang; Ou Congjie; Chen Jincan


    A unified model is presented for a class of combined energy systems, in which the systems mainly consist of a heat engine, a combustor and a counter-flow heat exchanger and the heat engine in the systems may have different thermodynamic cycle modes such as the Brayton cycle, Carnot cycle, Stirling cycle, Ericsson cycle, and so on. Not only the irreversibilities of the heat leak and finite-rate heat transfer but also the different cycle modes of the heat engine are considered in the model. On the basis of Newton's law, expressions for the overall efficiency and power output of the combined energy system with an irreversible Brayton cycle are derived. The maximum overall efficiency and power output and other relevant parameters are calculated. The general characteristic curves of the system are presented for some given parameters. Several interesting cases are discussed in detail. The results obtained here are very general and significant and can be used to discuss the optimal performance characteristics of a class of combined energy systems with different cycle modes. Moreover, it is significant to point out that not only the important conclusions obtained in Bejan's first combustor model and Peterson's general combustion driven model but also the optimal performance of a class of solar-driven heat engine systems can be directly derived from the present paper under some limit conditions

  12. Adsorption of aqueous metal ions on cattle-manure-compost based activated carbons. (United States)

    Zaini, Muhammad Abbas Ahmad; Okayama, Reiko; Machida, Motoi


    The objective of this study is to examine the suitability and performance of cattle-manure-compost (CMC) based activated carbons in removing heavy metal ions from aqueous solution. The influence of ZnCl(2) activation ratios and solution pH on the removal of Cu(II) and Pb(II) were studied. Pore texture, available surface functional groups, pH of point zero charge (pH(PZC)), thermogravimetric analysis and elemental compositions were obtained to characterize the activated carbons. Batch adsorption technique was used to determine the metal-binding ability of activated carbons. The equilibrium data were characterized using Langmuir, Freundlich and Redlich-Peterson models. It was found that the uptake of aqueous metal ions by activated carbons could be well described by Langmuir equation. It is suggested that the increase of surface area and mesopore ratio as a result of increasing activation ratios favored the removal of Cu(II), while activated carbon rich in acidic groups showed selective adsorption towards Pb(II). The preferable removal of Cu(II) over Pb(II) could be due to the rich nitrogen content as well as the higher mesoporous surface area in the CMC activated carbons. The impregnated CMC activated carbons also showed a better performance for Cu(II) removal at varying solution pH than Filtrasorb 400 (F400), while a similar performance was observed for Pb(II) removal.

  13. Modelling energy utilisation in broiler breeder hens. (United States)

    Rabello, C B V; Sakomura, N K; Longo, F A; Couto, H P; Pacheco, C R; Fernandes, J B K


    1. The objective of this study was to determine a metabolisable energy (ME) requirement model for broiler breeder hens. The influence of temperature on ME requirements for maintenance was determined in experiments conducted in three environmental rooms with temperatures kept constant at 13, 21 and 30 degrees C using a comparative slaughter technique. The energy requirements for weight gain were determined based upon body energy content and efficiency of energy utilisation for weight gain. The energy requirements for egg production were determined on the basis of egg energy content and efficiency of energy deposition in the eggs. 2. The following model was developed using these results: ME = kgW0.75(806.53-26.45T + 0.50T2) + 31.90G + 10.04EM, where kgW0.75 is body weight (kg) raised to the power 0.75, T is temperature ( degrees C), G is weight gain (g) and EM is egg mass (g). 3. A feeding trial was conducted using 400 Hubbard Hi-Yield broiler breeder hens and 40 Peterson males from 31 to 46 weeks of age in order to compare use of the model with a recommended feeding programme for this strain of bird. The application of the model in breeder hens provided good productive and reproductive performance and better results in feed and energy conversion than in hens fed according to strain recommendation. In conclusion, the model evaluated predicted an ME intake which matched breeder hens' requirements.

  14. Disease and pharmacologic risk factors for first and subsequent episodes of equine laminitis: A cohort study of free-text electronic medical records. (United States)

    Welsh, Claire E; Duz, Marco; Parkin, Timothy D H; Marshall, John F


    Electronic medical records from first opinion equine veterinary practice may represent a unique resource for epidemiologic research. The appropriateness of this resource for risk factor analyses was explored as part of an investigation into clinical and pharmacologic risk factors for laminitis. Amalgamated medical records from seven UK practices were subjected to text mining to identify laminitis episodes, systemic or intra-synovial corticosteroid prescription, diseases known to affect laminitis risk and clinical signs or syndromes likely to lead to corticosteroid use. Cox proportional hazard models and Prentice, Williams, Peterson models for repeated events were used to estimate associations with time to first, or subsequent laminitis episodes, respectively. Over seventy percent of horses that were diagnosed with laminitis suffered at least one recurrence. Risk factors for first and subsequent laminitis episodes were found to vary. Corticosteroid use (prednisolone only) was only significantly associated with subsequent, and not initial laminitis episodes. Electronic medical record use for such analyses is plausible and offers important advantages over more traditional data sources. It does, however, pose challenges and limitations that must be taken into account, and requires a conceptual change to disease diagnosis which should be considered carefully.

  15. Bridgman's concern

    International Nuclear Information System (INIS)

    Graham, R.A.


    In 1956 P.W. Bridgman published a letter to the editor in the Journal of Applied Physics reporting results of electrical resistance measurements on iron under static high pressure. The work was undertaken to verify the existence of a polymorphic phase transition at 130 kbar (13 GPa) reported in the same journal and year by the Los Alamos authors, Bancroft, Peterson and Minshall for high pressure, shock-compression loading. In his letter, Bridgman reported that he failed to find any evidence for the transition. Further, he raised some fundamental concerns as to the state of knowledge of shock-compression processes in solids. Later it was determined that Bridgman's static pressure scale was in error, and the shock observations became the basis for calibration of pressure values in static high pressure apparatuses. In spite of the error in pressure scales, Bridgman's concerns on descriptions of shock-compression processes were perceptive and have provided the basis for subsequent fundamental studies of shock-compressed solids. The present paper, written in response to receipt of the 1993 American Physical Society Shock-Compression Science Award, provides a brief contemporary assessment of those shock-compression issues which were the basis of Bridgman's 1956 concerns


    A literature review was conducted to identify available surface sediment sampling technologies with an ability to collect undisturbed sediments to depths of up to 1 meter below the water sediment interface. This survey was conducted using published literature and references, Environmental Protection Agency reports, professional sources, journal articles, internet web sites, sales brochures, and other sources as identified. For each piece of sampling equipment or sampling tool identified during the literature search, the following information was collected: general description of the equipment or tool, including its size, shape, weight, and composition; manufacturer's name, address, phone number, and email; a picture of the equipment or tool; the general mechanism of operation; sample volume collected; chemical and physical compatibility concerns; labor requirements; cost; and other requirements such as electrical power or specialized training. Sampling methodologies included in this investigation are grab or core types of sampling devices, as these types are most typically used in collecting surface sediments. In this review, 40 samplers were identified that included 13 grab samplers and 27 core samplers. Grab samplers included in the review are the Ponar, Birge-Ekman, Van Veen, Peterson, Mud Snapper, Scoopfish, Shipek, Smith-McIntyre, and others. Core samplers included in the review are the piston, splitcore, box, Vibracore, Mackereth, Ballchek, Craib, Gomex,

    Ozer, Ayla; Akkaya, Goenuel; Turabik, Meral


    In this study, the biosorption of Acid Blue 290 and Acid Blue 324 on Spirogyra rhizopus, a green algae growing on fresh water, was studied with respect to initial pH, temperature, initial dye concentration and biosorbent concentration. The optimum initial pH and temperature values for AB 290 and AB 324 biosorption were found to be 2.0, 30 deg. C and 3.0, 25 deg. C, respectively. It was observed that the adsorbed AB 290 and AB 324 amounts increased with increasing the initial dye concentration up to 1500 and 750 mg/L, respectively. The Langmuir, Freundlich, Redlich-Peterson and Koble-Corrigan isotherm models were applied to the experimental equilibrium data and the isotherm constants were determined by using Polymath 4.1 software. The monolayer coverage capacities of S. rhizopus for AB 290 and AB 324 dyes were found as 1356.6 mg/g and 367.0 mg/g, respectively. The intraparticle diffusion model and the pseudo-second order kinetic model were applied to the experimental data in order to describe the removal mechanism of these acidic dyes by S. rhizopus. The pseudo-second order kinetic model described very well the biosorption kinetics of AB 290 and AB 324 dyes. Thermodynamic studies showed that the biosorption of AB 290 and AB 324 on S. rhizopus was exothermic in nature

  18. Potential use of cotton plant wastes for the removal of Remazol Black B reactive dye

    Tunc, Ozlem; Tanaci, Hacer; Aksu, Zuemriye


    In this study, the potential use of cotton plant wastes - stalk (CS) and hull (CH) - as sorbents for the removal of Remazol Black B (RB5), a vinyl sulfone type reactive dye, was investigated. The results indicated that adsorption was strongly pH-dependent but slightly temperature-dependent for each sorbent-dye system. The Freundlich, Langmuir, Redlich-Peterson and Langmuir-Freundlich adsorption models were used for the mathematical description of adsorption equilibrium and isotherm constants were evaluated at 25 deg. C. All models except the Freundlich model were applicable for the description of dye adsorption by both sorbents in the concentration range studied. According to the Langmuir model, CS and CH sorbents exhibited the highest RB5 dye uptake capacities of 35.7 and 50.9 mg g -1 , respectively, at an initial pH value of 1.0. Simple mass transfer and kinetic models were applied to the experimental data to examine the mechanisms of adsorption and potential rate-controlling steps. It was found that both external mass transfer and intra-particle diffusion played an important role in the adsorption mechanisms of dye, and adsorption kinetics followed the pseudo second-order type kinetic model for each sorbent. Using the Langmuir model parameters, thermodynamic constant ΔG o was also evaluated for each sorption system

  19. Characterization of pore-expanded amino-functionalized mesoporous silicas directly synthesized with dimethyldecylamine and its application for decolorization of sulphonated azo dyes

    International Nuclear Information System (INIS)

    Yang Hong; Feng Qiyan


    With dimethyldecylamine (DMDA) as the expander, a new kind of pore-expanded amino-functionalized mesoporous silicas (PEAFMS) was directly synthesized under mild alkali condition. The characteristics of PEAFMS sample demonstrated that the presence of DMDA markedly augmented the average pore diameter (19.04 nm) and strongly enhanced its decolorization ability. Subsequently, acid mordant dark yellow GG (YGG) and reactive red violet X-2R (RVX) were chosen to assess its adsorption capacity for sulphonated azo dyes. The effect of initial pH was investigated and the decolorization mechanism was illuminated. Three isotherms were conducted and the goodness of fit increased as the following order: Freundlich < Langmuir < Redlich-Peterson. The maximum adsorption capacities of YGG and RVX onto PEAFMS were 1.967 and 0.957 mmol/g, respectively. Adsorption kinetic processes were better predicted by the pseudo-second-order rate equation than the pseudo-first-order one. Adsorption thermodynamic results suggested that the adsorption behavior of both dyes onto PEAFMS was spontaneous with the chemical nature. In addition, the regeneration of PEAFMS was proved to be feasible using NaOH as the strippant. After five cycles, PEAFMS still possessed a favorable adsorption capacity for dyes. It is safely concluded that PEAFMS could be a potential adsorbent for the dye removal from wastewater.

    Hafida Fahmiasari


    Full Text Available The disparity of the trading activities in Indonesia has triggered Indonesia Port Corporation to come up with the plan of Nusantara Pendulum, the future network of container shipping in Indonesia. The Sea Tollway plan is the modification of Nusantara Pendulum that is also envisioned by Indonesia President for Indonesia future backbone container plan. Both networks were designed to increase Indonesia container shipping flow from west to east and vice versa like a pendulum, thus results the reduced transport cost. This paper depicts the comparison of network efficiency analysis between these networks: Nusantara Pendulum, Sea Tollway, and the existing network. Two main methods that are used are Nagurney-Qiang and Jenelius-Peterson-Mattson. Mainly, these two methods use the efficiency calculation by considering parameters of demand (goods flow between each region and maritime transportation cost. It is concluded afterward that: 1 Sea Tollway is 8% more efficient than Nusantara Pendulum; 2 Sea Tollway and Nusantara Pendulum are ten times more efficient than current network; 3 Eastern ports in Indonesia (Bitung and Sorong urgently requisite a development.

  1. Development of a polyaniline-lignocellulose composite for optimal adsorption of Congo red. (United States)

    Debnath, Sushanta; Ballav, Niladri; Maity, Arjun; Pillay, Kriveshini


    A polyaniline lignocellulose composite (PLC) was synthesized and used in the removal of Congo red (CR) from aqueous solution. The adsorption process showed good fits to both the pseudo-second-order and pseudo-first-order models and the Redlich Peterson isotherm. Boundary layer diffusion was the rate-limiting step. The adsorption was spontaneous and endothermic. The combined effect of pH and initial dye concentration was antagonistic; the combined effect of initial dye concentration and temperature was synergistic, while the combined effect of pH and temperature was reciprocal. The maximum CR adsorption capacity of PLC was evaluated as 1672.5 mg g(-1). The optimal removal was calculated as 99.85% at pH 4.29, initial dye concentration of 28.5 mg L(-1) and adsorbent dosage of 0.69 g L(-1). The predicted removal capacity showed a good correlation to the experimental results. PLC has demonstrated a superior adsorption capacity to many other adsorbents reported and could be used as an efficient adsorbent for CR removal from industrial wastewater.

  2. Very broadband seismic background noise analysis of permanent good vaulted seismic stations (United States)

    Abd el-aal, Abd el-aziz Khairy


    This paper describes the results of a preliminary study conducted to analyze seismic background noise at sites of recently deployed very broadband stations of the Egyptian National Seismological Network (ENSN). The main purpose of the study is to assess the effects of permanent seismic vault construction and also to establish characteristics and origin of seismic noise at those sites. Another goal of this study is to determine the time needed for noise at those sites to stabilize. The power spectral densities of background noise at short period band (SP), very broadband (VBB), and ultra long period band (ULP) for each component of each broadband seismometer deployed in the different investigated sites are calculated. A MATLAB code has been developed that manages data processing and data analysis and compares the results with the high-noise model (NHNM) and low-noise model (NLNM) of Peterson (1993). Based on the obtained analysis, the noise stability and the efficiency of each station to record regional and teleseismic events are measured. The results of this study could be used in the future to evaluate station quality, to improve those processes that require background noise values, such as automatic association, and to improve the estimation of station and network detection and location thresholds.

  3. Photodynamic therapy--mechanism and employment. (United States)

    Szpringer, Ewa; Lutnicki, Krzysztof; Marciniak, Andrzej


    Photodynamic terapy (PDT) is a new treatment for a wide variety of malignancies and premalignant dysplasias, as well as some non-cancer indications. Therapeutic response to PTD is achieved through the activation of non-toxic photosensitiser located within neoplastic tissue, using visible light tuned to the appropriate absorption band of the photosensitiser molecule. This produces cytotoxic free radical such as singlet oxigen, which result in local photo-oxidation, cell damage and destruction of the tumour cells. Systemic administration of photosensitisers has been used with endoscopic light exposure to treat a variety of internal malignances. A topical drug delivery is used in the skin deseases treatment. The selective distribution of photosensitiser in the target tissue is the fundamental to the process of PDT. This tissue specific photosensitation and normal tissue sparing results in good healing and often very good cosmetic results. Peterson PTD can be used for the treatment of cutaneous lesions (e.g., SCC, BCC, Bowen's disease, mycosis fungoides, erythroplasia of Queyrat, Gorlin's Syndrome, actinic keratoses), lower genital tract neoplasia (VIN and CIN), gastrointestinal tumours, etc., as well as nononcological indications (e.g., acne, condyloma acuminatum, lichen planus, psoriasis, vitiligo, vulval lichen sclerosus, warts and verrucae).

  5. Approaching the Hartree-Fock Limit through the Complementary Auxiliary Basis Set Singles Correction and Auxiliary Basis Sets. (United States)

    Shaw, Robert A; Hill, J Grant


    Auxiliary basis sets for use in the resolution of the identity (RI) approximation in explicitly correlated methods are presented for the elements H-Ar. These extend the cc-pVnZ-F12/OptRI (n = D-Q) auxiliary basis sets of Peterson and co-workers by the addition of a small number of s- and p-functions, optimized so as to yield the greatest complementary auxiliary basis set (CABS) singles correction to the Hartree-Fock energy. The new sets, denoted OptRI+, also lead to a reduction in errors due to the RI approximation and hence an improvement in correlation energies. The atomization energies and heats of formation for a test set of small molecules, and spectroscopic constants for 27 diatomics, calculated at the CCSD(T)-F12b level, are shown to have improved error distributions for the new auxiliary basis sets with negligible additional effort. The OptRI+ sets retain all of the desirable properties of the original OptRI, including the production of smooth potential energy surfaces, while maintaining a compact nature.

  6. A comparison of the acoustic characteristics of American English and Cantonese vowels (United States)

    Zee, Eric


    The study compares the formant frequencies of the American English vowels [i, ɛ, squflg, squflg, u, I, U] (Peterson and Barney, 1952) and [i, V, a, squflg, u, I, U] in Cantonese (Zee, 2004). Results of the comparison show that the differences in formant values for the vowels between the two languages vary according to vowel type and gender. Between male speakers of the two languages, the differences in F-values are minimal for [i] and [squflg]. For [V, u], the difference between the two groups is mainly in F2, with [V] having a larger F2 and [u] a smaller F2 for Cantonese speakers. [squflg] in American English has smaller F1 and F2 than [a] in Cantonese. [I, U] occupy the position in between the level of [i, u] and level of [V, squflg] in the F1/F2 plane for American English speakers, and there is a noticeable difference in F2 between [I] and [V] and between [U] and [squflg]. For Cantonese speakers, [I, U] are on the same level of [V, squflg], and the difference in F2 is minimal between [I] and [V] and between [U] and [squflg]. The differences between female speakers of the two languages will also be presented.

  8. Adsorption of chromotrope dye onto activated carbons obtained from the seeds of various plants: Equilibrium and kinetics studies

    Directory of Open Access Journals (Sweden)

    K. Shahul Hameed


    Full Text Available The use of low-cost, easily obtained and eco-friendly adsorbents has been employed as an ideal alternative to the current expensive methods of removing dyes from wastewater. This study investigates the potential use of activated carbons such as aamla seed carbon (ASC, jambul seed carbon (JSC, tamarind seed carbon (TSC and soapnut carbon (SNC for the removal of chromotrope (CH dye from simulated wastewater. The obtained results were compared with that of Commercial Activated Carbon (CAC. The effects of different system variables, adsorbent dosage, pH and particle size were studied. The results showed that as the amount of the adsorbent increased, the amount adsorbed per unit mass decreased accordingly. Optimum pH value for dye adsorption was determined as ∼2.0. The adsorption of chromotrope fit well into pseudo-second-order rate equation. The adsorption also obeyed Langmuir and Redlich–Peterson equations better than Temkin, Freundlich and Dubinin–Radushkevich (D–R equations. The adsorption capacities of low cost adsorbents were found to be in the following order ASC > JSC > TSC > SNC. The activated carbons prepared were characterized by FT-IR and SEM analysis.

  9. Utilization of waste product (tamarind seeds) for the removal of Cr(VI) from aqueous solutions: equilibrium, kinetics, and regeneration studies. (United States)

    Gupta, Suresh; Babu, B V


    In the present study, an adsorbent was prepared from tamarind seeds and used after activation for the removal of Cr(VI) from aqueous solutions. The tamarind seeds were activated by treating them with concentrated sulfuric acid (98% w/w) at a temperature of 150 degrees C. The adsorption of Cr(VI) was found to be maximum at low values of initial pH in the range of 1-3. The adsorption process of Cr(VI) was tested with Langmuir, Freundlich, Redlich-Peterson, Koble-Corrigan, Tempkin, Dubinin-Radushkevich and Generalized isotherm models. Application of the Langmuir isotherm to the system yielded a maximum adsorption capacity of 29.7 mg/g at an equilibrium pH value ranging from 1.12 to 1.46. The adsorption process followed second-order kinetics and the corresponding rate constants obtained were 2.605 x 10(-3), 0.818 x 10(-3), 0.557 x 10(-3) and 0.811 x 10(-3) g/mg min(-1) for 50, 200, 300 and 400 mg/L of initial Cr(VI) concentration, respectively. The regenerated activated tamarind seeds showed more than 95% Cr(VI) removal of that obtained using the fresh activated tamarind seeds. A feasible solution is proposed for the disposal of the contaminants (acid and base solutions) containing high concentrations of Cr(VI) obtained during the regeneration (desorption) process.

  10. Enhanced mitigation of para-chlorophenol using stratified activated carbon adsorption columns. (United States)

    Sze, Michael Fan Fu; McKay, Gordon


    The adsorptive removal of toxic para-chlorophenol using activated carbon adsorption columns is a proven effective engineering process. This paper examined the possibility to stratify an adsorbent bed into layers, in order to enhance the adsorption process performance in terms of increased column service time and adsorbent bed saturation. Four different types of fixed-bed adsorption columns are used and compared under the same operating conditions, but with the variation of column geometry and activated carbon particle size stratification. The Type 3 column - a cylindrical column with particle stratification packing, is found to be the most efficient choice, as the extent of column service time and adsorbent bed saturation are the largest. This could eventually decrease the frequency of adsorbent replacement/regeneration and hence reduce the operating cost of the fixed-bed adsorption process. The Homogeneous Surface Diffusion Model (HSDM) was applied successfully to describe the dynamic adsorption of para-chlorophenol onto Filtrasorb 400 (F400) activated carbon in different types of columns. The Redlich-Peterson isotherm model equation, an experimentally derived external mass transfer correlation and a constant surface diffusivity are used in the HSDM. The optimised surface diffusivity of para-chlorophenol is found to be 1.20E-8 cm(2)/s, which is in good agreement with other phenolics/F400 carbon diffusing systems in literature.

  11. One-to-one embedding between honeycomb mesh and Petersen-Torus networks. (United States)

    Seo, Jung-Hyun; Sim, Hyun; Park, Dae-Heon; Park, Jang-Woo; Lee, Yang-Sun


    As wireless mobile telecommunication bases organize their structure using a honeycomb-mesh algorithm, there are many studies about parallel processing algorithms like the honeycomb mesh in Wireless Sensor Networks. This paper aims to study the Peterson-Torus graph algorithm in regard to the continuity with honeycomb-mesh algorithm in order to apply the algorithm to sensor networks. Once a new interconnection network is designed, parallel algorithms are developed with huge research costs to use such networks. If the old network is embedded in a newly designed network, a developed algorithm in the old network is reusable in a newly designed network. Petersen-Torus has been designed recently, and the honeycomb mesh has already been designed as a well-known interconnection network. In this paper, we propose a one-to-one embedding algorithm for the honeycomb mesh (HMn) in the Petersen-Torus PT(n,n), and prove that dilation of the algorithm is 5, congestion is 2, and expansion is 5/3. The proposed one-to-one embedding is applied so that processor throughput can be minimized when the honeycomb mesh algorithm runs in the Petersen-Torus.

  12. Moving forward with imperfect information: chapter 19 (United States)

    Averyt, Kristen; Brekke, Levi D.; Kaatz, Laurna; Welling, Leigh; Hartge, Eric H.; Iseman, Tom


    This chapter summarized the scope of what is known and not known about climate in the Southwestern United States. There is now more evidence and more agreement among climate scientists about the physical climate and related impacts in the Southwest compared with that represented in the 2009 National Climate Assessment (Karl, Melillo, and Peterson 2009). However, there remain uncertainties about the climate system, the complexities within climate models, the related impacts to the biophysical environment, and the use of climate information on decision making. Uncertainty is introduced in each step of the climate planning-an-response process--in the scenarios used to drive the climate models, the information used to construct the models, and the interpretation and use of the model' data for planning and decision making (Figure 19.1). There are server key challenge, drawn from recommendations of the authors of this report, that contribute to these uncertainties in the Southwest: - There is a dearth of climate observations at high elevations and on the lands of Native nations.

  13. Biosorption of nonylphenol on dead biomass of Rhizopus arrhizus encapsulated in chitosan beads. (United States)

    Lang, Weeranuch; Dejma, Chomawan; Sirisansaneeyakul, Sarote; Sakairi, Nobuo


    The nonylphenol (NP) biosorption and desorption potential for fungal biomass used under batch conditions was investigated using kinetics and isotherm models. Fungal biomass of Rhizopus arrhizus TISTR 3610 exhibited preferential uptake of NP, an endocrine disrupting chemicals. Sporangiospores, asexual spores, were immobilised in chitosan beads. The biosorption data of NP on the moist heat inactivated R. arrhizus-chitosan beads were analyzed using four popular adsorption isotherms and, by using non-linear least-regression with the solver add-in in Microsoft Excel, correlated in order with the Fritz-Schluender>Redlich-Peterson>Freundlich>Langmuir isotherms. The pseudo first-order kinetics was found to have the best fit with the experimental data. The diffusivity of NP in the R. arrhizus-chitosan beads was calculated using the shrinking core model, and the diffusivity values were in the ranges of 2.3736x10(-4)-1.8950x10(-4) cm(2) s(-1). Desorption to recover the adsorbed NP from the beads was performed in methanol and was best described using a pseudo second-order kinetic model.

  15. The Use of a Chlorophyll Meter (SPAD-502) for Field Determinations of Red Mangrove (Rhizophora Mangle L.) Leaf Chlorophyll Amount (United States)

    Connelly, Xana M.


    The red mangrove Rhizophora mangle L., is a halophytic woody spermatophyte common to the land-sea interface of tropical and subtropical intertidal zones. It has been reported that 60 to 75% of the coastline of the earth's tropical regions are lined with mangroves. Mangroves help prevent shoreline erosion, provide breeding, nesting and feeding areas for many marine animals and birds. Mangroves are important contributors of primary production in the coastal environment, and this is largely proportional to the standing crop of leaf chlorophylls. Higher intensities of ultraviolet radiation, resulting from stratospheric ozone depletion, can lead to a reduction of chlorophyll in terrestrial plants. Since the most common method for determining chlorophyll concentration is by extraction and this is labor intensive and time consuming, few studies on photosynthetic pigments of mangroves have been reported. Chlorophyll meter readings have been related to leaf chlorophyll content in apples and maples. It has also been correlated to nitrogen status in corn and cotton. Peterson et al., (1993) used a chlorophyll meter to detect nitrogen deficiency in crops and in determining the need for additional nitrogen fertilizer. Efforts to correlate chlorophyll meter measurements to chlorophyll content of mangroves have not been reported. This paper describes the use of a hand-held chlorophyll meter (Minolta SPAD-502) to determine the amount of red mangrove foliar chlorophyll present in the field.

  16. Novel activated carbon from Manihot esculenta Crantz for removal of Methylene Blue

    Directory of Open Access Journals (Sweden)

    Buscotin Horax Beakou


    Full Text Available The adsorptive removal of Methylene Blue by a novel bio char namely Cassava Rind Carbon was studied in a batch system. Moreover, several experiments were performed to optimize operating conditions of the adsorption process. Thermo gravimetric analysis investigates the thermal behaviour of the raw material. The surface functional groups were identified with Attenuated Total Reflectance Fourier Transform Infra-Red spectroscopy. The carbon surface was also characterised by BET surface area, scanning electron microscopy, X-ray diffraction and zero charge point of pH. Among the three kinetic models used to calculate the adsorption rate constants, the pseudo-second order was the most accurate. The experimental isotherms were analysed and Redlich-Peterson's model provided the best fit. The maximum capacity according to Langmuir model was 565 mg g−1 at 25 °C. The thermodynamic study revealed that the adsorption is endothermic, physical and random. The temperature, the mass of adsorbent and the concentration of dye were the three factors optimized in a Box Behnken Response Surface Methodology, with an optimal amount of adsorbed MB of 771 mg g−1.

  17. Adsorption Equilibrium and Kinetics of the Removal of Ammoniacal Nitrogen by Zeolite X/Activated Carbon Composite Synthesized from Elutrilithe

    Directory of Open Access Journals (Sweden)

    Yong Zhang


    Full Text Available Zeolite X/activated carbon composite material (X/AC was prepared from elutrilithe, by a process consisting of carbonization, activation, and subsequent hydrothermal transformation of aluminosilicate in alkaline solution, which was used for the removal of ammoniacal nitrogen from aqueous solutions. Adsorption kinetics, equilibrium, and thermodynamic were studied and fitted by various models. The adsorption kinetics is best depicted by pseudosecond-order model, and the adsorption isotherm fits the Freundlich and Redlich-Peterson model. This explains the ammoniacal nitrogen adsorption onto X/AC which was chemical adsorption in nature. Thermodynamic properties such as ΔG, ΔH, and ΔS were determined for the ammoniacal nitrogen adsorption, and the positive enthalpy confirmed that the adsorption process was endothermic. It can be inferred that ammoniacal nitrogen removal by X/AC composite is attributed to the ion exchange ability of zeolite X. Further, as a novel sorbent, this material has the potential application in removing ammoniacal nitrogen coexisting with other organic compounds from industrial wastewater.

  18. Mercury adsorption on a carbon sorbent derived from fruit shell of Terminalia catappa. (United States)

    Inbaraj, B Stephen; Sulochana, N


    A carbonaceous sorbent derived from the fruit shell of Indian almond (Terminalia catappa) by sulfuric acid treatment was used for the removal of mercury(II) from aqueous solution. Sorption of mercury depends on the pH of the aqueous solution with maximum uptake occurring in the pH range of 5-6. The kinetics of sorption conformed well to modified second order model among the other kinetic models (pseudo first order and pseudo second order) tested. The Langmuir and Redlich-Peterson isotherm models defined the equilibrium data precisely compared to Freundlich model and the monolayer sorption capacity obtained was 94.43 mg/g. Sorption capacity increased with increase in temperature and the thermodynamic parameters, DeltaH degrees , DeltaS degrees and DeltaG degrees , indicated the Hg(II) sorption to be endothermic and spontaneous with increased randomness at the solid-solution interface. An optimum carbon dose of 4 g/l was required for the maximum uptake of Hg(II) from 30 mg/l and the mathematical relationship developed showed a correlation of 0.94 between experimental and calculated percentage removals for any carbon dose studied. About 60% of Hg(II) adsorbed was recovered from the spent carbon at pH 1.0, while 94% of it was desorbed using 1.0% KI solution.

  19. The Neuromodulator of Exploration: A Unifying Theory of the Role of Dopamine in Personality

    Directory of Open Access Journals (Sweden)

    Colin G DeYoung


    Full Text Available The neuromodulator dopamine is centrally involved in reward, approach behavior, exploration, and various aspects of cognition. Variations in dopaminergic function are assumed to be associated with variations in personality, but exactly which traits are influenced by dopamine remains an open question. This paper proposes a theory of the role of dopamine in personality that organizes and explains the diversity of findings, utilizing the division of the dopaminergic system into value coding and salience coding neurons (Bromberg-Martin, Matsumoto, and Hikosaka, 2010. The value coding system is proposed to be related primarily to Extraversion and the salience coding system to Openness/Intellect. Global levels of dopamine influence the higher order personality factor, Plasticity, which comprises the shared variance of Extraversion and Openness/Intellect. All other traits related to dopamine are linked to Plasticity or its subtraits. The general function of dopamine is to promote exploration, by facilitating engagement with cues of specific reward (value and cues of the reward value of information (salience. This theory constitutes an extension of the entropy model of uncertainty (EMU; Hirsh, Mar, & Peterson, 2012, enabling EMU to account for the fact that uncertainty is an innate incentive reward as well as an innate threat. The theory accounts for the association of dopamine with traits ranging from sensation and novelty seeking, to impulsivity and aggression, to achievement striving, creativity, and cognitive abilities, to the overinclusive thinking characteristic of schizotypy.

    Konstantyner, Thais Claudia Roma de Oliveira; Silva, Aline Medeiros da; Tanaka, Luana Fiengo; Marques, Heloísa Helena de Sousa; Latorre, Maria do Rosário Dias de Oliveira


    In clinical practice, recurrence of thrush is common in children living with HIV/AIDS. The aim of this study was to determine the factors associated with time spent free of oral candidiasis using survival analysis for recurrent events. A retrospective cohort study was carried out with 287 children treated between 1985 and 2009 at a reference center in the city of São Paulo, Brazil. The Prentice, Williams and Peterson model for recurrent events was used for the investigation of factors associated with the time free of oral candidiasis. The following factors were associated with the time patients were free of oral candidiasis: moderate immunodepression (HR = 2.5; p = 0.005), severe immunodepression (HR = 3.5; p < 0.001), anemia (HR = 3.3; p < 0.001), malnutrition (HR = 2.6; p = 0.004), hospitalization (HR = 2.2; p < 0.001), monotherapy (HR = 0.5; p = 0.006), dual therapy (HR = 0.3; p < 0.001) and triple therapy/highly active antiretroviral therapy (HR = 0.1; p < 0.001). The method analyzed in the present study proved useful for the investigation of recurrent events in patients living with HIV/AIDS.

  2. Racial Discipline Disproportionality in Montessori and Traditional Public Schools: A Comparative Study Using the Relative Rate Index

    Directory of Open Access Journals (Sweden)

    Katie E. Brown


    Full Text Available Research from the past 40 years indicates that African American students are subjected to exclusionary discipline, including suspension and expulsion, at rates two to three times higher than their White peers (Children’s Defense Fund, 1975; Skiba, Michael, Nardo, & Peterson, 2002. Although this phenomenon has been studied extensively in traditional public schools, rates of racially disproportionate discipline in public Montessori schools have not been examined. The purpose of this study is to examine racial discipline disproportionality in Montessori public elementary schools as compared to traditional elementary schools. The Relative Rate Index (RRI is used as a measure of racially disproportionate use of out-of-school suspensions (Tobin & Vincent, 2011. Suspension data from the Office of Civil Rights Data Collection was used to generate RRIs for Montessori and traditional elementary schools in a large urban district in the Southeast. While statistically significant levels of racial discipline disproportionality are found in both the Montessori and traditional schools, the effect is substantially less pronounced in Montessori settings. These findings suggest that Montessori schools are not immune to racially disproportionate discipline and should work to incorporate more culturally responsive classroom management techniques. Conversely, the lower levels of racially disproportionate discipline in the Montessori schools suggests that further study of discipline in Montessori environments may provide lessons for traditional schools to promote equitable discipline.

  3. Striation Formation in Cylindrical Liners Made of Various Materials Driven by a 1 MA Pulsed Power Generator (United States)

    Atoyan, Levon; Byvank, Tom; Engelbrecht, Joseph; Greenly, John; Pikuz, Sergei; Potter, William; Shelkovenko, Tania; Kusse, Bruce; Hammer, David


    Peterson et al. found on the 20 MA Z machine that, without any applied external axial magnetic field, horizontal striations appear in radiographic images of a metal liner [Phys. Plasmas 19, 092701, 2012], a result that has been reproduced on other pulsed power machines since. In this work we present experimental results of horizontal striations on the 1 MA, 100-200 ns COBRA pulsed power generator [T. A. Shelkovenko et al., Rev. Sci. Instrum. 77, 10F521, 2006]. The pattern is observed in our experiments using extreme ultraviolet imaging, laser imaging, and X-ray backlighting. Using this combination of diagnostics, we were able to view simultaneously the pattern near the liner surface as well as in the higher density portion of the liner, displaying features with different wavelengths. Furthermore, materials such as Al, Cu, and Ti will be used for the liner to determine if the striation formation is affected by the nature of the material.

  4. Synthesis of titania modified silica-pillared clay (SPC) with highly ordered interlayered mesoporous structure for removing toxic metal ion Cr(VI) from aqueous state (United States)

    Mao, Huihui; Zhu, Kongnan; Li, Baoshan; Yao, Chao; Kong, Yong


    Titanium-functionalized silica-pillared clays synthesized through post synthetic route was utilized as adsorbers for the removal of Cr(VI) ions from aqueous solutions under different temperatures and initial concentrations. The starting mesostructured silica-pillared clay is assembled by intragallery ammonia-catalyzed hydrolysis of tetraethoxysilane using cationic surfactant as gallery template, and subsequently, the formed interlayered pore walls were decorated with nano-sized TiO2 particle through organic titanium functionalization process. The kind of structural transformation has been confirmed by X-ray diffraction (XRD), nitrogen adsorption-desorption isotherms, Fourier transform infrared (FT-IR) analysis, UV-vis diffuse reflectance spectroscopy (DRS), elemental analysis (XRF), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Such results indicate that most of the grafted titanium species was combined with Si-OH on the surface of gallery pores. By changing the concentration of organic titanium source during synthesis, the porous structure system is effected. Under suitable conditions, these materials exhibit high adsorption capacity and efficiency. Qualitative estimates of the thermodynamic parameters showed that the overall adsorption process is spontaneous (ΔG° 0). The adsorption isotherms of Cr(VI) on titanium-functionalized silica-pillared clay were best fitted by Redlich-Peterson models. Detail results of thermodynamics and kinetics are also presented.

    Full Text Available Due to the crucial role textbooks play in any educational system, an urgent need is felt to examine, evaluate, and choose the most suitable ones available. This study is an attempt to critically examine and uncover the hidden curriculum in First Certificate Masterclass (FCM that is taught at Navid institute in Iran. To this aim, FCM was deeply examined to identify any instances of Western cultural norms and preferences and their potential influences on Iranian EFL (English as a Foreign Language learners’ thoughts and ideologies. Peterson’s distinction between Big “C” culture and little “c” culture constituted the theoretical framework of the study. To collect the necessary data, all passages, texts, exercises, and even listening excerpts were closely studied and evaluated by the researcher. Results indicated that among the elements of little “c” culture introduced by Peterson, preferences or tastes, food, hobbies, popular music, and popular issues could mainly be observed in the book. Furthermore, the majority of the representations introduced and depicted in the book were incompatible with Iranian Muslim people’s ideologies and beliefs. Implications of these findings for Iranian material developers and textbook writers as well as English teachers are also discussed.

  6. [Character strengths and well-being in Japanese children and youth: creating good habits]. (United States)

    Imura, Tomoya; Aoki, Tazuko; Takahashi, Tomoko; Nonaka, Yoichiro; Yamada, Tsuyoshi


    Character education in the US aims to establish good habits corresponding to good character. The purpose of this study was to determine the structure of character strengths and the relations among these strengths and wellbeing in Japanese children and youth. Peterson and Seligman (2004) developed a classification of character strengths called VIA-IS. We thought, however, that VIA-IS had too many items to use with school children. We selected 15 categories and developed a questionnaire for Japanese children and youth. Fourth to eighth grade students (N = 1,351) answered questionnaires in Study 1. We found four categories of character strengths, each of which consisted of 25 items: perseverance-honesty, courage-ideas, compassion-gratitude, and fairness-care. These categories were very similar to previous research findings which simplified the categories. In Study 2, we found a positive relationship among four categories of character strengths and well-being, which we called the hope scale, life satisfaction scale, subjective happiness scale, and social support scale. We discussed what additional research was needed for establishing good habits using our categories with children and youth in schools.

  7. Staphylococcus aureus hijacks a skin commensal to intensify its virulence: immunization targeting β-hemolysin and CAMP factor. (United States)

    Lo, Chih-Wei; Lai, Yiu-Kay; Liu, Yu-Tsueng; Gallo, Richard L; Huang, Chun-Ming


    The need for a new anti-Staphylococcus aureus therapy that can effectively cripple bacterial infection, neutralize secretory virulence factors, and lower the risk of creating bacterial resistance is undisputed. Here, we propose what is, to our knowledge, a previously unreported infectious mechanism by which S. aureus may commandeer Propionibacterium acnes, a key member of the human skin microbiome, to spread its invasion and highlight two secretory virulence factors (S. aureus β-hemolysin and P. acnes CAMP (Christie, Atkins, Munch-Peterson) factor) as potential molecular targets for immunotherapy against S. aureus infection. Our data demonstrate that the hemolysis and cytolysis by S. aureus were noticeably augmented when S. aureus was grown with P. acnes. The augmentation was significantly abrogated when the P. acnes CAMP factor was neutralized or β-hemolysin of S. aureus was mutated. In addition, the hemolysis and cytolysis of recombinant β-hemolysin were markedly enhanced by recombinant CAMP factor. Furthermore, P. acnes exacerbated S. aureus-induced skin lesions in vivo. The combination of CAMP factor neutralization and β-hemolysin immunization cooperatively suppressed the skin lesions caused by coinfection of P. acnes and S. aureus. These observations suggest a previously unreported immunotherapy targeting the interaction of S. aureus with a skin commensal.

The NASA Marshall Space Flight Center (MSFC) Lightning Nitrogen Oxides Model (LNOM) [Koshak et al., 2009, 2010, 2011; Koshak and Peterson 2011, 2013] analyzes VHF Lightning Mapping Array (LMA) and National Lightning Detection Network(TradeMark) (NLDN) data to estimate the lightning nitrogen oxides (LNOx) produced by individual flashes. Figure 1 provides an overview of LNOM functionality. Benefits of LNOM: (1) Does away with unrealistic "vertical stick" lightning channel models for estimating LNOx; (2) Uses ground-based VHF data that maps out the true channel in space and time to < 100 m accuracy; (3) Therefore, true channel segment height (ambient air density) is used to compute LNOx; (4) True channel length is used! (typically tens of kilometers since channel has many branches and "wiggles"); (5) Distinction between ground and cloud flashes are made; (6) For ground flashes, actual peak current from NLDN used to compute NOx from lightning return stroke; (7) NOx computed for several other lightning discharge processes (based on Cooray et al., 2009 theory): (a) Hot core of stepped leaders and dart leaders, (b) Corona sheath of stepped leader, (c) K-change, (d) Continuing Currents, and (e) M-components; and (8) LNOM statistics (see later) can be used to parameterize LNOx production for regional air quality models (like CMAQ), and for global chemical transport models (like GEOS-Chem).

  9. The Exxon Valdez oil spill revisited and the dangers of normative science. (United States)

    Landis, Wayne G


    In the July 2006 issue of Integrated Environmental Assessment and Management, a paper by Harwell and Gentile was published assessing the present ecological significance of the impacts from the Exxon Valdez oil spill (EVOS). First, this paper compares the major conclusions of Harwell and Gentile and a paper reviewing the current impacts of EVOS by Peterson et al as published by Science in 2003. Stark differences exist between the conclusions of the 2 papers regarding continuing impacts. Part of the difference appears to be the infusion of different social values or policy goals into each. Normative science is the use or interpretation of data in support of specific values or policies. Examples of values or policies intertwined with science are constructs such as ecosystem health, ecosystem integrity, ecological significance, and recovery. Examination of the environmental risk assessment and toxicology literature reveals that the symptoms of normative science are common and the implications widespread. Separation of science from policy or at a minimum a transparent acknowledgment of the science-policy interaction is clearly necessary in order to obtain a clear picture of the ecological system under investigation.

  10. Regulation of the muscle fiber microenvironment by activated satellite cells during hypertrophy (United States)

    Fry, Christopher S.; Lee, Jonah D.; Jackson, Janna R.; Kirby, Tyler J.; Stasko, Shawn A.; Liu, Honglu; Dupont-Versteegden, Esther E.; McCarthy, John J.; Peterson, Charlotte A.


    Our aim in the current study was to determine the necessity of satellite cells for long-term muscle growth and maintenance. We utilized a transgenic Pax7-DTA mouse model, allowing for the conditional depletion of > 90% of satellite cells with tamoxifen treatment. Synergist ablation surgery, where removal of synergist muscles places functional overload on the plantaris, was used to stimulate robust hypertrophy. Following 8 wk of overload, satellite cell-depleted muscle demonstrated an accumulation of extracellular matrix (ECM) and fibroblast expansion that resulted in reduced specific force of the plantaris. Although the early growth response was normal, an attenuation of hypertrophy measured by both muscle wet weight and fiber cross-sectional area occurred in satellite cell-depleted muscle. Isolated primary myogenic progenitor cells (MPCs) negatively regulated fibroblast ECM mRNA expression in vitro, suggesting a novel role for activated satellite cells/MPCs in muscle adaptation. These results provide evidence that satellite cells regulate the muscle environment during growth.—Fry, C. S., Lee, J. D., Jackson, J. R., Kirby, T. J., Stasko, S. A., Liu, H., Dupont-Versteegden, E.

    Reports are available on silver binding capacity of some microorganisms. However, reports on the equilibrium studies on biosorption of silver by macrofungi are seldom known. The present study was carried out in a batch system using dead biomass of macrofungus Pleurotus platypus for the sorption of Ag(I). P. platypus exhibited the highest silver uptake of 46.7 mg g -1 of biomass at pH 6.0 in the presence of 200 mg L -1 Ag(I) at 20 deg. C. Kinetic studies based on fractional power, zero order, first order, pseudo-first order, Elovich, second order and pseudo-second order rate expressions have been carried out. The results showed a very good compliance with the pseudo-first order model. The experimental data were analyzed using two parameter isotherms (Langmuir, Freundlich, Dubinin-Radushkevich, Temkin and Halsey), three parameter isotherms (Redlich-Peterson, Sips, Khan, Koble-Corrigan, Hill, Toth, Radke-Prausmitz, Jossens, Langmuir-Freundlich), four parameter isotherms (Weber-van Vliet, Fritz-Schlunder, Baudu) and five parameter isotherm (Fritz-Schlunder). Thermodynamic parameters of the biosorption (ΔG, ΔH and ΔS) were also determined. The present study confirmed that macrofungus P. platypus may be used as a cost effective efficient biosorbent for the removal of Ag(I) ions from aqueous solution.

  13. More people - more energy: it seems obvious enough, but Carter plan ignores population. (United States)

    Behrens, S


    In President Carter's National Energy Plan, there are variable factors, including the coal production rate, standards for home insulation and auto mileage, various taxes, but not the population growth rate. The latter factor is considered to be beyond the influence of public policy; it is a constant. This seems irrational to zero population growth proponents, for there are alternatives to continued U.S. population growth, and these alternatives are more readily attainable than some of the elements in Carter's plan. With some national initiatives in population planning, energy use would be considerably less. Thus, the question remains - Why would Carter not deal with the population factor? 1 reason for this is the fact that population planning is a long-term approach; the results are indirect and not reflected immediately in energy comsumption. Yet, a start must be made in the short-term if there are ever to be long-term benefits. Russell Peterson has suggested that Carter could be ignoring the population factor because of "political sensitivity." Carter's people have ignored the population issue, and press coverage following Carter's energy pronouncements has excluded the population factor. In a situation such as this there seems little hope for increased public awareness of the population factor in energy or other public concerns.

  14. Comparison of adsorption equilibrium models and error functions for the study of sulfate removal by calcium hydroxyapatite microfibrillated cellulose composite. (United States)

    Hokkanen, Sanna; Bhatnagar, Amit; Koistinen, Ari; Kangas, Teija; Lassi, Ulla; Sillanpää, Mika


    In the present study, the adsorption of sulfates of sodium sulfate (Na 2 SO 4 ) and sodium lauryl sulfate (SLS) by calcium hydroxyapatite-modified microfibrillated cellulose was studied in the aqueous solution. The adsorbent was characterized using elemental analysis, Fourier transform infrared, scanning electron microscope and elemental analysis in order to gain the information on its structure and physico-chemical properties. The adsorption studies were conducted in batch mode. The effects of solution pH, contact time, the initial concentration of sulfate and the effect of competing anions were studied on the performance of synthesized adsorbent for sulfate removal. Adsorption kinetics indicated very fast adsorption rate for sulfate of both sources (Na 2 SO 4 and SLS) and the adsorption process was well described by the pseudo-second-order kinetic model. Experimental maximum adsorption capacities were found to be 34.53 mg g -1 for sulfates of SLS and 7.35 mg g -1 for sulfates of Na 2 SO 4. The equilibrium data were described by the Langmuir, Sips, Freundlich, Toth and Redlich-Peterson isotherm models using five different error functions.

  15. Density Functional Theory and the Basis Set Truncation Problem with Correlation Consistent Basis Sets: Elephant in the Room or Mouse in the Closet? (United States)

    Feller, David; Dixon, David A


    Two recent papers in this journal called into question the suitability of the correlation consistent basis sets for density functional theory (DFT) calculations, because the sets were designed for correlated methods such as configuration interaction, perturbation theory, and coupled cluster theory. These papers focused on the ability of the correlation consistent and other basis sets to reproduce total energies, atomization energies, and dipole moments obtained from "quasi-exact" multiwavelet results. Undesirably large errors were observed for the correlation consistent basis sets. One of the papers argued that basis sets specifically optimized for DFT methods were "essential" for obtaining high accuracy. In this work we re-examined the performance of the correlation consistent basis sets by resolving problems with the previous calculations and by making more appropriate basis set choices for the alkali and alkaline-earth metals and second-row elements. When this is done, the statistical errors with respect to the benchmark values and with respect to DFT optimized basis sets are greatly reduced, especially in light of the relatively large intrinsic error of the underlying DFT method. When judged with respect to high-quality Feller-Peterson-Dixon coupled cluster theory atomization energies, the PBE0 DFT method used in the previous studies exhibits a mean absolute deviation more than a factor of 50 larger than the quintuple zeta basis set truncation error.

  16. Measurements of secondary electron cross sections by the pulsed electron beam time-of-flight method. I. Molecular nitrogen

    International Nuclear Information System (INIS)

    Goruganthu, R.R.; Wilson, W.G.; Bonham, R.A.


    The secondary electron cross sections for gaseous molecular nitrogen are reported at ejection angles of 30, 45, 60, 75, 90, 105, 120, 135 and 150 0 , for the energy range 1.5 eV to 20 eV and incident electron energy of 1 keV. The pulsed electron beam time-of-flight methd was employed. The results were placed on an absolute scale by normalization to the elastic scattering. They were compared, where possible, with those reported by Opal, Beaty, and Peterson (OBP). The agreement is somewhat better when the OBP data are divided by 0.53 + 0.47 sintheta as suggested by Rudd and DuBois. Fits of our data by Legendre-polynomial expansions are used to estimate the low-energy portion of the cross-section, dsigma/dE. This work suggests that existing experimental cross sections for secondary electron ejection as a function of angle and ejected energy may be no better known than +-40%, especially in the low energy region. 7 references, 14 figures, 2 tables

  17. Kinetic and isotherm error optimization studies for adsorption of atrazine and imidacloprid on bark of Eucalyptus tereticornis L. (United States)

    Mandal, Abhishek; Singh, Neera


    The aim of this study was to establish the bark of Eucalyptus tereticornis L. (EB) as a low cost bio-adsorbent for the removal of imidacloprid and atrazine from aqueous medium. The pseudo-first-order (PFO), pseudo-second-order (PSO), Elovich and intra-particle diffusion (IPD) models were used to describe the kinetic data and rate constants were evaluated. Adsorption data was analysed using ten 2-, 3- and 4-parameter models viz. Freundlich, Jovanovic, Langmuir, Temkin, Koble-Corrigan, Redlich-Peterson, Sips, Toth, Radke-Prausnitz, and Fritz-Schluender isotherms. Six error functions were used to compute the best fit single component isotherm parameters by nonlinear regression analysis. The results showed that the sorption of atrazine was better explained by PSO model, whereas the sorption of imidacloprid followed the PFO kinetic model. Isotherm model optimization analysis suggested that the Freundlich along with Koble-Corrigan, Toth and Fritz-Schluender were the best models to predict atrazine and imidacloprid adsorption onto EB. Error analysis suggested that minimization of chi-square (χ(2)) error function provided the best determination of optimum parameter sets for all the isotherms.

  18. Adsorption of metribuzin from aqueous solution using magnetic and nonmagnetic sustainable low-cost biochar adsorbents. (United States)

    Essandoh, Matthew; Wolgemuth, Daniel; Pittman, Charles U; Mohan, Dinesh; Mlsna, Todd


    Switchgrass biochar (SGB) was made by fast pyrolysis in an auger-fed reactor at 425 °C with a solid residence time of 60 s in the pyrolysis zone during bio-oil production. Magnetic switchgrass biochar (MSGB) was prepared by iron oxide precipitation onto the biochar surface using an aqueous Fe 3+ /Fe 2+ solution followed by NaOH treatment. Both the SGB and the MSGB were characterized by FTIR, SEM, SEM-EDX, TGA, pH pzc , elemental analysis, and surface area measurements. Batch sorption studies of metribuzin from aqueous solutions were carried out at different pH values, adsorbate concentrations, and temperatures. The adsorption of metribuzin onto both biochars was highest at a pH of 2. Adsorption isotherms were evaluated from 25 to 45 °C using the Freundlich, Langmuir, Redlich-Peterson, Toth, Sips, Koble-Corrigan, and Radke-Prausnitz adsorption models. Langmuir adsorption capacities at pH 2 were Q 0 SGB  ~ 151, 223, and 205 mg/g and Q 0 MSGB  ~ 155, 205, and 155 mg/g at 25, 35, and 45 °C, respectively. Low-cost magnetization of the biochar occurred without significant loss of absorption capacity, enabling facile separation of slurried biochar from liquids following contaminate absorption.

  19. Perchlorate adsorption onto orange peel modified by cross-linking amine groups from aqueous solutions. (United States)

    Zhang, Lixiang; Yang, Zhiquan; Li, Ting; Zhou, Shaoqi; Wu, Zhenyi


    Orange peel was made into a highly efficient bio-sorbent by modification with cross-linking amine groups for perchlorate removal. Bench-scale experiments were performed to explore the factors affecting the perchlorate adsorption onto the modified orange peel (MOP). Perchlorate could be removed effectively at a wide range of pH (from 1.5 to 11). The maximum adsorption capacity of MOP for perchlorate was calculated as 154.1 mg/g within 15 min. The Redlich-Peterson model was fitted to the adsorption isotherm very well (R2>0.99). The adsorption process was spontaneous and exothermic, which was proved by thermodynamic parameters (Gibbs energy and enthalpy). The pseudo-second-order kinetic model could provide satisfactory fitting of the experimental data (R2>0.99). The scanning electron microscopy and energy-dispersive X-ray analysis indicated that the surface of MOP became smooth and the contents of N and Cl in MOP were increased during the modification process. Elemental analysis results showed that the nitrogen content in MOP was increased to 5.5%, while it was 1.06% in orange peel. The adsorption mechanism was also explored using zeta potential and Fourier transform infrared spectroscopy analysis. Ion exchange was the primary mechanism responsible for uptake of perchlorate onto MOP.

  20. Aging well: Processing speed inhibition and working memory related to balance and aerobic endurance. (United States)

    Zettel-Watson, Laura; Suen, Meagan; Wehbe, Lara; Rutledge, Dana N; Cherry, Barbara J


    The present study explored whether certain physical performance measures could be linked to specific cognitive domains in healthy older adults. A total of 50 adults (mean age 69.5 years, SD 8.1) were evaluated on physical performance using measures of balance (Fullerton Advanced Balance Scale), functional mobility (8-ft up-and-go), lower body strength (30-s chair stand), gait (30-ft walk velocity) and aerobic endurance (6-min walk). Cognitive measures included Stroop Color-Word Test, Digit Span Backward, Trail Making Tests, Everyday Problems Test, Digit Symbol Substitution and a Brown-Peterson test. Principal component analyses reduced cognition to domains of processing speed, inhibition and working memory. Hierarchical regression analyses were carried out with age and each physical measure as potential predictors of the three cognitive domains. The balance scale and 6-min walk were specifically associated with processing speed, inhibition and working memory. Better dynamic balance and aerobic endurance predicted enhanced processing speed, inhibition and working memory in older adults, with these last two domains considered components of executive function.

  1. Adsorption capacity of phenolic compounds onto cellulose and xylan

    Directory of Open Access Journals (Sweden)

    Telma dos Santos Costa


    Full Text Available The interaction between three phenolic compounds (catechin, caffeic acid and ferulic acid onto two dietary fibres (cellulose and xylan has been evaluated to inquire possible interferences on the biodisponibility of phenolic compounds. The adsorption kinetics were performed using solutions containing 100 mg/L of phenolic compounds during a contact time ranging between 10 and 120 minutes at pH 2.0, 4.5, and 7.0. After the kinetics, isotherms were obtained using phenolic compounds concentration ranging between 10 and 80 mg/L during 60 minutes, at pH 2.0 and 7.0 and temperature of 36 °C. Results indicate that adsorbed quantities mainly changed in function of pH, however the maximum adsorption was only of 0.978 mg of caffeic acid/g of xylan at pH 2 and after 60 min. Redlich-Peterson model were able to predict the adsorption isotherms of all phenolic compounds onto cellulose, except for caffeic acid at pH 7.0. The low adsorption capacities observed suggest that both dietary fibres are unable to compromise the biodisponibility of phenolic compounds, especially in the small intestine, where they are partially absorbed.

  2. Equilibrium modeling of mono and binary sorption of Cu(II and Zn(II onto chitosan gel beads

    Nastaj Józef


    Full Text Available The objective of the work are in-depth experimental studies of Cu(II and Zn(II ion removal on chitosan gel beads from both one- and two-component water solutions at the temperature of 303 K. The optimal process conditions such as: pH value, dose of sorbent and contact time were determined. Based on the optimal process conditions, equilibrium and kinetic studies were carried out. The maximum sorption capacities equaled: 191.25 mg/g and 142.88 mg/g for Cu(II and Zn(II ions respectively, when the sorbent dose was 10 g/L and the pH of a solution was 5.0 for both heavy metal ions. One-component sorption equilibrium data were successfully presented for six of the most useful three-parameter equilibrium models: Langmuir-Freundlich, Redlich-Peterson, Sips, Koble-Corrigan, Hill and Toth. Extended forms of Langmuir-Freundlich, Koble-Corrigan and Sips models were also well fitted to the two-component equilibrium data obtained for different ratios of concentrations of Cu(II and Zn(II ions (1:1, 1:2, 2:1. Experimental sorption data were described by two kinetic models of the pseudo-first and pseudo-second order. Furthermore, an attempt to explain the mechanisms of the divalent metal ion sorption process on chitosan gel beads was undertaken.

  3. [Structural Equation Modeling of Quality of Work Life in Clinical Nurses based on the Culture-Work-Health Model]. (United States)

    Kim, Miji; Ryu, Eunjung


    The purpose of this study was to construct and test a structural equation model of quality of work life for clinical nurses based on Peterson and Wilson's Culture-Work-Health model (CWHM). A structured questionnaire was completed by 523 clinical nurses to analyze the relationships between concepts of CWHM-organizational culture, social support, employee health, organizational health, and quality of work life. Among these conceptual variables of CWHM, employee health was measured by perceived health status, and organizational health was measured by presenteeism. SPSS21.0 and AMOS 21.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factors affecting quality of work life among clinical nurses. The goodness-of-fit statistics of the final modified hypothetical model are as follows: χ²=586.03, χ²/df=4.19, GFI=.89, AGFI=.85, CFI=.91, TLI=.90, NFI=.89, and RMSEA=.08. The results revealed that organizational culture, social support, organizational health, and employee health accounted for 69% of clinical nurses' quality of work life. The major findings of this study indicate that it is essential to create a positive organizational culture and provide adequate organizational support to maintain a balance between the health of clinical nurses and the organization. Further repeated and expanded studies are needed to explore the multidimensional aspects of clinical nurses' quality of work life in Korea, including various factors, such as work environment, work stress, and burnout.

  4. Cosmic reionization on computers. II. Reionization history and its back-reaction on early galaxies

    Gnedin, Nickolay Y. [Particle Astrophysics Center, Fermi National Accelerator Laboratory, Batavia, IL 60510 (United States); Kaurov, Alexander A., E-mail:, E-mail: [Department of Astronomy and Astrophysics, The University of Chicago, Chicago, IL 60637 (United States)


    We compare the results from several sets of cosmological simulations of cosmic reionization, produced under the Cosmic Reionization On Computers project, with existing observational data on the high-redshift Lyα forest and the abundance of Lyα emitters. We find good consistency with the observational measurements and previous simulation work. By virtue of having several independent realizations for each set of numerical parameters, we are able to explore the effect of cosmic variance on observable quantities. One unexpected conclusion we are forced into is that cosmic variance is unusually large at z > 6, with both our simulations and, most likely, observational measurements still not fully converged for even such basic quantities as the average Gunn-Peterson optical depth or the volume-weighted neutral fraction. We also find that reionization has little effect on the early galaxies or on global cosmic star formation history, because galaxies whose gas content is affected by photoionization contain no molecular (i.e., star-forming) gas in the first place. In particular, measurements of the faint end of the galaxy luminosity function by the James Webb Space Telescope are unlikely to provide a useful constraint on reionization.

    Highlights: ► Al 13 modification changes As(V) sorption mechanism of montmorillonites. ► Intercalated ion charges mainly affects As(V) adsorption kinetics. ► Uniform pore structure exhibit more excellent As(V) adsorption performance. - Abstract: Four modified montmorillonite adsorbents with varied Al 13 contents (i.e., Na-Mont, AC-Mont, PAC 20 -Mont, and Al 13 -Mont) were synthesized and characterized by N 2 adsorption/desorption, X-ray diffraction, and Fourier-transform infrared analyses. The arsenate adsorption performance of the four adsorbents were also investigated to determine the role of intercalated Al 13 , especially its high purity, high positive charge (+7), and special Keggin structure. With increased Al 13 content, the physicochemical properties (e.g., surface area, structural uniformity, basal spacing, and pore volume) and adsorption performance of the modified montmorillonites were significantly but disproportionately improved. The adsorption data well fitted the Freundlich and Redlich–Peterson isotherm model, whereas the kinetic data better correlated with the pseudo-second-order kinetic model. The arsenate sorption mechanism of the montmorillonites changed from physical to chemisorption after intercalation with Al 13 . Increasing charges of the intercalated ions enhanced the arsenate adsorption kinetics, but had minimal effect on the structural changes of the montmorillonites. The uniform pore structure formed by intercalation with high-purity Al 13 greatly enhanced the pore diffusion and adsorption rate of arsenate, resulting in the high adsorption performance of Al 13 -Mont.

  6. Multiscale functions, scale dynamics, and applications to partial differential equations (United States)

    Cresson, Jacky; Pierret, Frédéric


    Modeling phenomena from experimental data always begins with a choice of hypothesis on the observed dynamics such as determinism, randomness, and differentiability. Depending on these choices, different behaviors can be observed. The natural question associated to the modeling problem is the following: "With a finite set of data concerning a phenomenon, can we recover its underlying nature? From this problem, we introduce in this paper the definition of multi-scale functions, scale calculus, and scale dynamics based on the time scale calculus [see Bohner, M. and Peterson, A., Dynamic Equations on Time Scales: An Introduction with Applications (Springer Science & Business Media, 2001)] which is used to introduce the notion of scale equations. These definitions will be illustrated on the multi-scale Okamoto's functions. Scale equations are analysed using scale regimes and the notion of asymptotic model for a scale equation under a particular scale regime. The introduced formalism explains why a single scale equation can produce distinct continuous models even if the equation is scale invariant. Typical examples of such equations are given by the scale Euler-Lagrange equation. We illustrate our results using the scale Newton's equation which gives rise to a non-linear diffusion equation or a non-linear Schrödinger equation as asymptotic continuous models depending on the particular fractional scale regime which is considered.

  7. Radical Institutional Economics and Fakery for the 21st Century

    Directory of Open Access Journals (Sweden)

    Svetlana G. Kirdina-Chandler


    Full Text Available The article summarises some results of the discussions about radical institutional economics (RIE for the 21st century. The discussions took place at the 38th Conference of the Association for Institutional Thought, held in April 2017 (San Francisco, California, US. The contribution of radical institutional economists of the 1990s in the development of institutional thought is presented in the article. The works of William M. Dugger – the founder of RIE – are stressed, as well as the roles of other radical institutionalists such as Edythe Miller, J. Ron Stanfield, Ron Phillips, Dell Champlin, Janice Peterson, Charles Whalen, Doug Brown, Rick Tilman, Louis Junker and Howard Sherman. The reasons for the reintroduction of radical institutional economics onto the agenda in the modern US are considered, among them being the increasing fakery in economies and the growth of inequality in incomes and distribution of economic benefits. The article then suggests a hypothesis that an external factor in the radicalisation of science and public consciousness in Western and other countries is associated with a change in world leaders and poles of growth, and is a turning point in history. It is argued that the power of countries in which the X-matrix dominates is beginning to surpass the influence of countries where the Y-matrix dominates.

  8. Personalized microbial network inference via co-regularized spectral clustering. (United States)

    Imangaliyev, Sultan; Keijser, Bart; Crielaard, Wim; Tsivtsivadze, Evgeni


    We use Human Microbiome Project (HMP) cohort (Peterson et al., 2009) to infer personalized oral microbial networks of healthy individuals. To determine clustering of individuals with similar microbial profiles, co-regularized spectral clustering algorithm is applied to the dataset. For each cluster we discovered, we compute co-occurrence relationships among the microbial species that determine microbial network per cluster of individuals. The results of our study suggest that there are several differences in microbial interactions on personalized network level in healthy oral samples acquired from various niches. Based on the results of co-regularized spectral clustering we discover two groups of individuals with different topology of their microbial interaction network. The results of microbial network inference suggest that niche-wise interactions are different in these two groups. Our study shows that healthy individuals have different microbial clusters according to their oral microbiota. Such personalized microbial networks open a better understanding of the microbial ecology of healthy oral cavities and new possibilities for future targeted medication.

  9. Guided ion beam and theoretical studies of the bond energy of SmS. (United States)

    Armentrout, P B; Demireva, Maria; Peterson, Kirk A


    Previous work has shown that atomic samarium cations react with carbonyl sulfide to form SmS + + CO in an exothermic and barrierless process. To characterize this reaction further, the bond energy of SmS + is determined in the present study using guided ion beam tandem mass spectrometry. Reactions of SmS + with Xe, CO, and O 2 are examined. Results for collision-induced dissociation processes with all three molecules along with the endothermicity of the SmS + + CO → Sm + + COS exchange reaction are combined to yield D 0 (Sm + -S) = 3.37 ± 0.20 eV. The CO and O 2 reactions also yield a SmSO + product, with measured endothermicities that indicate D 0 (SSm + -O) = 3.73 ± 0.16 eV and D 0 (OSm + -S) = 1.38 ± 0.27 eV. The SmS + bond energy is compared with theoretical values characterized at several levels of theory, including CCSD(T) complete basis set extrapolations using all-electron basis sets. Multireference configuration interaction calculations with explicit spin-orbit calculations along with composite thermochemistry using the Feller-Peterson-Dixon method and all-electron basis sets were also explored for SmS + , and for comparison, SmO, SmO + , and EuO.

  10. The personality traits of observers and the acquaintanceship as factors of assessment of others

    Directory of Open Access Journals (Sweden)

    Smederevac Snežana


    Full Text Available The main purpose of this study was to determine the relation between the degree of acquaintance and assessment of other persons’ personality traits and attribution of their behaviour. The second aim was to examine relation between personality traits of observers and their perception of actor’s personality traits and attribution of actor’s behaviour. The study was conducted on a sample of 76 subjects divided into two groups, on the basis of degree of acquaintance with actors. First group estimated a close person, a best friend. Second group estimated a person they are not acquainted with. This person was described in an invented interview. In the first part of the research, all subjects completed The Big Five Inventory (John, 1991. In the second part of the research, subjects estimated personality traits of actors (using BFI and attributed actor’s behaviour using The Attributional Style Questionnaire (Peterson et al., 1982. The results suggest that there are at least two types of bias in estimation of other people. One type is in relation with acquaintance.

  11. Adsorption characteristics of amino acids on to calcium oxalate. (United States)

    He, Junbin; Lin, Rihui; Long, Han; Liang, Yuwei; Chen, Yangyang


    Adsorption of amino acids on to calcium oxalate found in urinary calculus has been studied and the adsorption characteristics were analyzed. Pseudo-first-order, pseudo-second-order and intraparticle diffusion models were used to fit the kinetics data. The pseudo-second-order model best described the dynamic behavior of the adsorption process. The uptake of glutamic acid and aspartic acid were found to decrease as solution pH increasing from 4 to 8. The experimental data obtained at different pH conditions were analyzed and fitted by Langmuir, Freundlich, Redlich-Peterson, Temkin and Sips isotherm models using linear and nonlinear regression analysis. Error analysis (correlation coefficient, residual root mean square error and chi-square test) showed that the Langmuir I isotherm model and the non-linear form of Sips isotherm model should be primarily adopted for fitting the equilibrium data. The maximum adsorption capacity of glutamic acid and aspartic acid onto calcium oxalate monohydrate crystals are 0.059 and 0.066μmol/g at pH 4, respectively. These studies have the vital significance for research aimed at exploring the role of urinary amino acids effect the formation process of calcium oxalate crystals found in urinary calculus and for potential application in the design of synthetic peptides used for urinary calculi therapy.

  12. Adsorption of BTX (benzene, toluene, o-xylene, and p-xylene) from aqueous solutions by modified periodic mesoporous organosilica. (United States)

    Moura, Cícero P; Vidal, Carla B; Barros, Allen L; Costa, Luelc S; Vasconcellos, Luiz C G; Dias, Francisco S; Nascimento, Ronaldo F


    The capacity of a periodic mesoporous organosilica (PMO) to adsorb the aromatic compounds benzene, toluene, o-, and p-xylenes (BTX), which are usually present in produced waters, was investigated under both column and batch processes. The PMO was synthesized by condensation of 1,4 bis(triethoxisilyl)benzene (BTEB) under acidic conditions by using structure-directing agent (SDA) Pluronic P123 in the presence of KCl. Thermogravimetric analysis showed that the presence of the surfactant decreases the thermal stability of the PMO. The small-angle X-ray diffraction pattern, as well as the nitrogen adsorption/desorption isotherm measurements, revealed that the synthesized material has a crystalline structure, with hexagonally-ordered cylindrical mesopores. The adsorption kinetics study indicated an adsorption equilibrium time of 50 min and also showed that the data best fitted the pseudo-first order kinetic model. The intraparticle diffusion model was also tested and pointed to the occurrence of such process in all cases. Both Langmuir and Temkin models best represented the adsorption isotherms of toluene; Langmuir and Redlich-Peterson models best represented the data obtained for the other compounds. Adsorption capacity decreases in the order benzene>o-xylene>p-xylene>toluene. Satisfactory results were observed in the application of the synthesized PMO for the removal of BTX from aqueous solution. Copyright © 2011 Elsevier Inc. All rights reserved.

  13. Adsorption of lead(II) from water by carbon nanotubes: equilibrium, kinetics, and thermodynamics. (United States)

    Rahbari, Meysam; Goharrizi, Ataallah Soltani


    Adsorption of lead(II) from water on carbon nanotubes (CNTs) was investigated using a series of batch adsorption experiments. The adsorption rate was studied experimentally at various temperatures, contact times, and initial pH and lead(II) concentrations. It was observed that a considerable amount of lead(II) was adsorbed during the first 5 minutes of contact time. The pH of the solution strongly influenced the amount of adsorption, and the best results were obtained when pH value was approximately 6. For the adsorption isotherm, the experimental data were analyzed by three two-parameter isotherms (Langmuir, Freundlich, and Temkin) and four three-parameter isotherms (Redhich-Peterson, Sips, Toth, and Khan). The three kinetic models used to test the experimental data were Lagergren first-order, second-order, and the Elovich equation. The results obtained from the study of the thermodynamic parameters showed that the adsorption of lead(II) onto CNTs was a spontaneous and endothermic process.

  14. Utilization of water hyacinth weed (Eichhornia crassipes) for the removal of Pb(II), Cd(II) and Zn(II) from aquatic environments: an adsorption isotherm study. (United States)

    Mahamadi, C; Nharingo, T


    The potential of Eichhornia crassipes biomass for the adsorption of three metal ions, Pb(II), Cd(II) and Zn(II), from aqueous solution was studied using five two-parameter adsorption isotherm equations--Langmuir, Freundlich, Flory-Huggins, Temkin and Redlich-Peterson isotherms. The equilibrium adsorption data were obtained at different initial metal ion concentrations (C0 = 10-60 mg/L), 3 h contact time, 30 degrees C temperature, a dosage of 2 g/L, agitation rate of 150 rpm and buffered at pH 4.84. Langmuir isotherms gave monolayer sorption capacities (qm) of 26.32, 12.60 and 12.55 mg/g for Pb(II), Cd(II) and Zn(II) metal ions, respectively. The same trend of metal uptake was indicated by plots of sorption favourability (S(F)). Negative values of deltaGads0 indicated that the adsorption was spontaneous and exothermic in nature, and values from the Temkin isotherm constant, bT, suggested a mechanism consistent with an ion-exchange process. The results from these studies indicated that E. crassipes biomass has promising potential for the removal of toxic metals from aquatic environments.

  15. Modeling of boldine alkaloid adsorption onto pure and propyl-sulfonic acid-modified mesoporous silicas. A comparative study. (United States)

    Geszke-Moritz, Małgorzata; Moritz, Michał


    The present study deals with the adsorption of boldine onto pure and propyl-sulfonic acid-functionalized SBA-15, SBA-16 and mesocellular foam (MCF) materials. Siliceous adsorbents were characterized by nitrogen sorption analysis, transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier-transform infrared (FT-IR) spectroscopy and thermogravimetric analysis. The equilibrium adsorption data were analyzed using the Langmuir, Freundlich, Redlich-Peterson, and Temkin isotherms. Moreover, the Dubinin-Radushkevich and Dubinin-Astakhov isotherm models based on the Polanyi adsorption potential were employed. The latter was calculated using two alternative formulas including solubility-normalized (S-model) and empirical C-model. In order to find the best-fit isotherm, both linear regression and nonlinear fitting analysis were carried out. The Dubinin-Astakhov (S-model) isotherm revealed the best fit to the experimental points for adsorption of boldine onto pure mesoporous materials using both linear and nonlinear fitting analysis. Meanwhile, the process of boldine sorption onto modified silicas was described the best by the Langmuir and Temkin isotherms using linear regression and nonlinear fitting analysis, respectively. The values of adsorption energy (below 8kJ/mol) indicate the physical nature of boldine adsorption onto unmodified silicas whereas the ionic interactions seem to be the main force of alkaloid adsorption onto functionalized sorbents (energy of adsorption above 8kJ/mol).

  16. Equilibrium and kinetic studies on free cyanide adsorption from aqueous solution by activated carbon. (United States)

    Behnamfard, Ali; Salarirad, Mohammad Mehdi


    Adsorption equilibrium and kinetics of free cyanide onto activated carbon were investigated in the batch tests, and the effects of contact time (1-72 h) and initial cyanide concentrations in the range of 102-532 mg/L were studied. Linear regression was used to determine the best fit of equilibrium and kinetics expressions. The two-parameter models including Freundlich, Dubinin-Radushkevich, Temkin and four different linearized forms of Langmuir and three-parameter models including Redlich-Peterson and Koble-Corrigan were employed for fitting the equilibrium data and it was found that, three-parameter models fitted the data better than the two-parameter models and among the three-parameter models the equilibrium data are best represented by Koble-Corrigan model. A number of kinetic models including fractional power, zero order, first order, pseudo-first order, Elovich, second order, intraparticle diffusion and four different linearized forms of pseudo-second order models were tested to fit the kinetic data. The latter was found to be consistent with the data. Intraparticle diffusion plots show that the adsorption process of free cyanide is a two steps process. In the first step, the adsorption of cyanide is fast while in the second step, cyanide adsorption slows down.

  17. Tetracycline adsorption onto activated carbons produced by KOH activation of tyre pyrolysis char. (United States)

    Acosta, R; Fierro, V; Martinez de Yuso, A; Nabarlatz, D; Celzard, A


    Tyre pyrolysis char (TPC), produced when manufacturing pyrolysis oil from waste tyre, was used as raw material to prepare activated carbons (ACs) by KOH activation. KOH to TPC weight ratios (W) between 0.5 and 6, and activation temperatures from 600 to 800 °C, were used. An increase in W resulted in a more efficient development of surface area, microporosity and mesoporosity. Thus, ACs derived from TPC (TPC-ACs) with specific surface areas up to 814 m(2) g(-1) were obtained. TPC, TPC-ACs and a commercial AC (CAC) were tested for removing Tetracycline (TC) in aqueous phase, and systematic adsorption studies, including equilibrium, kinetics and thermodynamic aspects, were performed. Kinetics was well described by the pseudo-first order model for TPC, and by a pseudo second-order kinetic model for ACs. TC adsorption equilibrium data were also fitted by different isotherm models: Langmuir, Freundlich, Sips, Dubinin-Radushkevich, Dubinin-Astokov, Temkin, Redlich-Peterson, Radke-Prausnitz and Toth. The thermodynamic study confirmed that TC adsorption onto TPC-ACs is a spontaneous process. TC adsorption data obtained in the present study were compared with those reported in the literature, and differences were explained in terms of textural properties and surface functionalities. TPC-ACs had similar performances to those of commercial ACs, and might significantly improve the economic balance of the production of pyrolysis oil from waste tyres. Copyright © 2016 Elsevier Ltd.

  18. Adsorption and kinetic studies of seven different organic dyes onto magnetite nanoparticles loaded tea waste and removal of them from wastewater samples. (United States)

    Madrakian, Tayyebeh; Afkhami, Abbas; Ahmadi, Mazaher


    Adsorption of seven different organic dyes from aqueous solutions onto magnetite nanoparticles loaded tea waste (MNLTW) was studied. MNLTW was prepared via a simple method and was fully characterized. The properties of this magnetic adsorbent were characterized by scanning electron microscopy and X-ray diffraction. Adsorption characteristics of the MNLTW adsorbent was examined using Janus green, methylene blue, thionine, crystal violet, Congo red, neutral red and reactive blue 19 as adsorbates. Dyes adsorption process was thoroughly studied from both kinetic and equilibrium points of view for all adsorbents. The experimental isotherm data were analyzed using Langmuir, Freundlich, Sips, Redlich-Peterson, Brouers-Sotolongo and Temkin isotherms. The results from Langmuir isotherm indicated that the capacity of MNLTW for the adsorption of cationic dyes was higher than that for anionic dyes. The adsorption kinetics was tested for the pseudo-first order and pseudo-second order kinetic models at different experimental conditions. Copyright © 2012 Elsevier B.V. All rights reserved.

  19. The Relationship Between Luminosity and Broad-Line Region Size in Active Galactic Nuclei

    DEFF Research Database (Denmark)

    Kaspi, Shai; Maoz, Dan; Netzer, Hagai


    We reinvestigate the relationship between the characteristic broad-line region size (R_blr) and the Balmer emission-line, X-ray, UV, and optical continuum luminosities. Our study makes use of the best available determinations of R_blr for a large number of active galactic nuclei (AGNs) from...... Peterson et al. Using their determinations of R_blr for a large sample of AGNs and two different regression methods, we investigate the robustness of our correlation results as a function of data sub-sample and regression technique. Though small systematic differences were found depending on the method...... of analysis, our results are generally consistent. Assuming a power-law relation R_blr \\propto L^\\alpha, we find the mean best-fitting \\alpha is about 0.67+/-0.05 for the optical continuum and the broad H\\beta luminosity, about 0.56+/-0.05 for the UV continuum luminosity, and about 0.70+/-0.14 for the X...

  20. Atypical anterior wall fracture of the acetabulum: case series of anterior acetabular rim fracture without involvement of the pelvic brim. (United States)

    Lenarz, Christopher J; Moed, Berton R


    The purpose of this study was to describe a form of anterior wall acetabular fracture, which has been inadequately defined in the literature. Retrospective analysis of consecutive patients. Level 1 trauma center. A retrospective analysis of consecutive acetabulum patients treated by a single surgeon between 1999 and 2005 identified 6 patients with a form of anterior wall fracture without involvement of the pelvic brim. All fractures were treated operatively. Open reduction and internal fixation through an anterior surgical approach. Final radiographic appearance and modified Merle d'Aubigne score. All 6 cases demonstrated characteristics of an atypical fracture of the anterior wall, involving the anterior rim of the acetabulum similar in nature to those described for the posterior wall, rather than the standard anterior wall fracture type described by Letournel. Of the 6 cases that were identified, 5 had follow-up 1 year or greater with a mean modified Merle d'Aubigne Score of 17 (range: 17-18). A form of anterior wall acetabular fracture exists, which involves the anterior acetabular rim without involvement of the pelvic brim. It can occur in young patients with high-energy mechanisms of injury, as well as in the elderly with low-energy trauma. With appropriate surgical management, using a modified Smith-Peterson approach, good to excellent clinical outcomes should be expected.

  1. Toward a culture-by-context perspective on negotiation: negotiating teams in the United States and Taiwan. (United States)

    Gelfand, Michele J; Brett, Jeanne; Gunia, Brian C; Imai, Lynn; Huang, Tsai-Jung; Hsu, Bi-Fen


    Within the United States, teams outperform solos in negotiation (Thompson, Peterson, & Brodt, 1996). The current research examined whether this team advantage generalizes to negotiators from a collectivist culture (Taiwan). Because different cultures have different social norms, and because the team context may amplify the norms that are salient in a particular culture (Gelfand & Realo, 1999), we predicted that the effect of teams on negotiation would differ across cultures. Specifically, we predicted that since harmony norms predominate in collectivist cultures like Taiwan, the team context would amplify a concern with harmony, leading Taiwanese teams to negotiate especially suboptimal outcomes. In support, 2 studies showed that Taiwanese teams negotiated less-optimal outcomes than Taiwanese solos. We also used a moderated-mediation analysis to investigate the mechanism (Hayes, 2012), documenting that the interactive effect of culture and context on outcomes was mediated by harmony norms. By showing that the same situational conditions (team negotiations) can have divergent effects on negotiation outcomes across cultures, our results point toward a nuanced, sociocontextual view that moves beyond the culture-as-main-effect approach to studying culture and negotiations.

  2. Behavioral and neural correlates of disrupted orienting attention in posttraumatic stress disorder. (United States)

    Russman Block, Stefanie; King, Anthony P; Sripada, Rebecca K; Weissman, Daniel H; Welsh, Robert; Liberzon, Israel


    Prior work has revealed that posttraumatic stress disorder (PTSD) is associated with altered (a) attentional performance and (b) resting-state functional connectivity (rsFC) in brain networks linked to attention. Here, we sought to characterize and link these behavioral and brain-based alterations in the context of Posner and Peterson's tripartite model of attention. Male military veterans with PTSD (N = 49; all deployed to Iraq or Afghanistan) and healthy age-and-gender-matched community controls (N = 26) completed the Attention Network Task. A subset of these individuals (36 PTSD and 21 controls) also underwent functional magnetic resonance imaging (fMRI) to assess rsFC. The behavioral measures revealed that the PTSD group was impaired at disengaging spatial attention, relative to the control group. FMRI measures further revealed that, relative to the control group, the PTSD group exhibited greater rsFC between the salience network and (a) the default mode network, (b) the dorsal attention network, and (c) the ventral attention network. Moreover, problems with disengaging spatial attention increased the rsFC between the networks above in the control group, but not in the PTSD group. The present findings link PTSD to both altered orienting of spatial attention and altered relationships between spatial orienting and functional connectivity involving the salience network. Interventions that target orienting and disengaging spatial attention may be a new avenue for PTSD research.

  3. The potential use of activated carbon prepared from Ziziphus species for removing dyes from waste waters (United States)

    Regti, Abdelmajid; Laamari, My Rachid; Stiriba, Salah-Eddine; El Haddad, Mohammadine


    In this study, the adsorption potential of activated carbon prepared from Ziziphus mauritiana nuts for the removal of methylene blue (MB) from aqueous solution has been investigated using batch mode experiments. The effects of some operating parameters on the removal dye such as, initial pH (2-12), temperature (298-328 K), initial MB concentration (20-100 mg L-1), and contact time (5-70 min) were investigated. Adsorption kinetic showed that the rate adsorption followed the pseudo-second-order kinetic model. Four adsorption isotherms models were applied to experimental equilibrium data (Langmuir, Freundlich, Redlich-Peterson, and Fritz-Schlunder) and the different constants were calculated using non-linear equations models. Fritz-Schlunder model was found the best one to describe the adsorption process which suggests that the adsorption of MB onto activated carbon derived from Ziziphus mauritiana is heterogeneous with a multilayer. Thermodynamic adsorption showed that the process was endothermic and spontaneous in nature.

  4. Do positive psychology exercises work? A replication of Seligman et al. (2005). (United States)

    Mongrain, Myriam; Anselmo-Matthews, Tracy


    The current work replicated a landmark study conducted by Seligman and colleagues (2005) that demonstrated the long-term benefits of positive psychology exercises (PPEs). In the original study, two exercises administered over 1 week ("Three Good Things" and "Using your Signature Strengths in a New Way") were found to have long-lasting effects on depression and happiness (Seligman, Steen, Park, & Peterson, 2005). These exercises were tested here using the same methodology except for improvements to the control condition, and the addition of a second "positive placebo" to isolate the common factor of accessing positive, self-relevant constructs. This component control design was meant to assess the effect of expectancies for success (expectancy control), as well the cognitive access of positive information about the self (positive placebo). Repeated measures analyses showed that the PPEs led to lasting increases in happiness, as did the positive placebo. The PPEs did not exceed the control condition in producing changes in depression over time. Brief, positive psychology interventions may boost happiness through a common factor involving the activation of positive, self-relevant information rather than through other specific mechanisms. Finally, the effects of PPEs on depression may be more modest than previously assumed. © 2012 Wiley Periodicals, Inc.

A heterogeneous group of patients, including 51 patients with pemphigus vulgaris, one with pemphigus vegetans, nine with pemphigus foliaceus, five with paraneoplastic pemphigus, four with epidermolysis bullosa acquisita, and one with both bullous pemphigoid and graft vs host disease was included in this survey. Overall the monoclonal antibody seems to be effective in that 69% of patients showed complete response, 25% of patients showed partial response, whereas 6% of patients showed progressive disease. Six deaths occurred in association with the treatment, with four of these deaths in patients with paraneoplastic pemphigus, a disease characteristically resistant to conventional medication and with a high mortality rate. Of note, 11 patients who received combined rituximab and intravenous immune globulin treatments had the best outcome: complete response without any serious side effects. Therefore further investigation on rituximab with controlled clinical trial is a worthy pursuit.Keywords: blistering diseases, skin, anti-CD20, pemphigus, epidermolysis bullosa acquisita

  6. The Plausibility of Tonal Evolution in the Malay Dialect Spoken in Thailand: Evidence from an Acoustic Study

    Directory of Open Access Journals (Sweden)

    Phanintra Teeranon


    Full Text Available The F0 values of vowels following voiceless consonants are higher than those of vowels following voiced consonants; high vowels have a higher F0 than low vowels. It has also been found that when high vowels follow voiced consonants, the F0 values decrease. In contrast, low vowels following voiceless consonants show increasing F0 values. In other words, the voicing of initial consonants has been found to counterbalance the intrinsic F0 values of high and low vowels (House and Fairbanks 1953, Lehiste and Peterson 1961, Lehiste 1970, Laver 1994, Teeranon 2006. To test whether these three findings are applicable to a disyllabic language, the F0 values of high and low vowels following voiceless and voiced consonants were studied in a Malay dialect of the Austronesian language family spoken in Pathumthani Province, Thailand. The data was collected from three male informants, aged 30-35. The Praat program was used for acoustic analysis. The findings revealed the influence of the voicing of initial consonants on the F0 of vowels to be greater than that of the influence of vowel height. Evidence from this acoustic study shows the plausibility for the Malay dialect spoken in Pathumthani to become a tonal language by the influence of initial consonants rather by the influence of the high-low vowel dimension.

  7. Adsorption characteristics of As(III) from aqueous solution on iron oxide coated cement (IOCC)

    Kundu, Sanghamitra; Gupta, A.K.


    Contamination of potable groundwater with arsenic is a serious health hazard, which calls for proper treatment before its use as drinking water. The objective of the present study is to assess the effectiveness of iron oxide coated cement (IOCC) for As(III) adsorption from aqueous solution. Batch studies were conducted to study As(III) adsorption onto IOCC at ambient temperature as a function of adsorbent dose, pH, contact time, initial arsenic concentration and temperature. Kinetics reveal that the uptake of As(III) ion is very rapid and most of fixation occurs within the first 20 min of contact. The pseudo-second order rate equation successfully described the adsorption kinetics. Langmuir, Freundlich, Redlich-Peterson (R-P), and Dubinin-Radushkevich (D-R) models were used to describe the adsorption isotherms at different initial As(III) concentrations and at 30 g l -1 fixed adsorbent dose. The maximum adsorption capacity of IOCC for As(III) determined from the Langmuir isotherm was 0.69 mg g -1 . The mean free energy of adsorption (E) calculated from the D-R isotherm was found to be 2.86 kJ mol -1 which suggests physisorption. Thermodynamic parameters indicate an exothermic nature of adsorption and a spontaneous and favourable process. The results suggest that IOCC can be suitably used for As(III) removal from aqueous solutions

  8. Adsorption of rhodamine B and methylene blue dyes using waste of seeds of Aleurites Moluccana, a low cost adsorbent

    Debora Luiza Postai


    Full Text Available Removal of the cationic dyes rhodamine B (RhB and methylene blue (MB by waste seeds Aleurites moluccana (WAM was studied in a batch system. The adsorbent was characterized by Fourier transform infrared spectroscopy (FTIR, thermogravimetric analysis (TGA, point of zero charge measurement, and the Boehm titration method. The effects of contact time and pH were investigated for the removal of cationic dyes. An increase in pH from 3 to 9 was accompanied by an approximately three-fold increase in the amount of dye adsorbed. The adsorptions equilibrium values were obtained and analyzed using the Langmuir, Freundlich, Sips, and Redlich–Peterson equations, the Sips isotherm being the one that showed the best correlation with the experimental values. The maximum adsorption capacities of the dyes were 178 mg/g for the MB and 117 mg/g for the RhB. The kinetic sorption was evaluated by the pseudo-first-order, pseudo-second-order, and intraparticle diffusion models, where it was observed that sorption follows the pseudo-second-order kinetic model. The study of thermodynamics showed that the adsorption is a spontaneous and endothermic process. The results indicate that waste seeds of A. moluccana could be used as a low cost material for the removal of cationic dyes from wastewater.

E-mail:; Akkaya, Goenuel [University of Mersin, Department of Chemical Engineering, 33343 Ciftlikkoey-Mersin (Turkey); Turabik, Meral [University of Mersin, Higher Vocational School of Mersin, Chemical Prog., Ciftlikkoey-Mersin (Turkey)


    In this study, the biosorption of Acid Blue 290 and Acid Blue 324 on Spirogyra rhizopus, a green algae growing on fresh water, was studied with respect to initial pH, temperature, initial dye concentration and biosorbent concentration. The optimum initial pH and temperature values for AB 290 and AB 324 biosorption were found to be 2.0, 30 deg. C and 3.0, 25 deg. C, respectively. It was observed that the adsorbed AB 290 and AB 324 amounts increased with increasing the initial dye concentration up to 1500 and 750 mg/L, respectively. The Langmuir, Freundlich, Redlich-Peterson and Koble-Corrigan isotherm models were applied to the experimental equilibrium data and the isotherm constants were determined by using Polymath 4.1 software. The monolayer coverage capacities of S. rhizopus for AB 290 and AB 324 dyes were found as 1356.6 mg/g and 367.0 mg/g, respectively. The intraparticle diffusion model and the pseudo-second order kinetic model were applied to the experimental data in order to describe the removal mechanism of these acidic dyes by S. rhizopus. The pseudo-second order kinetic model described very well the biosorption kinetics of AB 290 and AB 324 dyes. Thermodynamic studies showed that the biosorption of AB 290 and AB 324 on S. rhizopus was exothermic in nature.

  10. Modeling the recurrent failure to thrive in less than two-year children: recurrent events survival analysis. (United States)

    Saki Malehi, Amal; Hajizadeh, Ebrahim; Ahmadi, Kambiz; Kholdi, Nahid


    This study aimes to evaluate the failure to thrive (FTT) recurrent event over time. This longitudinal study was conducted during February 2007 to July 2009. The primary outcome was growth failure. The analysis was done using 1283 children who had experienced FTT several times, based on recurrent events analysis. Fifty-nine percent of the children had experienced the FTT at least one time and 5.3% of them had experienced it up to four times. The Prentice-Williams-Peterson (PWP) model revealed significant relationship between diarrhea (HR=1.26), respiratory infections (HR=1.25), urinary tract infections (HR=1.51), discontinuation of breast-feeding (HR=1.96), teething (HR=1.18), initiation age of complementary feeding (HR=1.11) and hazard rate of the first FTT event. Recurrence nature of the FTT is a main problem, which taking it into account increases the accuracy in analysis of FTT event process and can lead to identify different risk factors for each FTT recurrences.

  11. Intracellular accumulation of norfloxacin in Mycobacterium smegmatis. (United States)

    Corti, S; Chevalier, J; Cremieux, A


    To evaluate the intracellular accumulation of norfloxacin in mycobacteria, two methods were used with Mycobacterium smegmatis. A radiometric method (K. V. Cundy, C. E. Fasching, K. E. Willard, and L. R. Peterson, J. Antimicrob. Chemother. 28:491-497, 1991) was used without great modification, but the fluorometric method (P. G. S. Mortimer and L. J. V. Piddock, J. Antimicrob. Chemother. 28:639-653, 1991) was changed considerably. Indeed, adsorption of the quinolone to the bacterial surface was characterized by measuring the level of accumulation of 0 degree C. Taking into account the adsorption, the pH of the washing buffer was increased from 7.0 to 9.0 to improve the desorption of norfloxacin from the cell surface. Both the fluorometric method, with the technical improvement, and the radiometric method could be used to estimate the intracellular accumulation of norfloxacin, which resulted from the difference between the whole uptake measured at 37 degrees C and the adsorption measured at 0 degrees C. A total of 35 ng of norfloxacin per mg of cells (dry weight) penetrated into the M. smegmatis cell, and the steady state was achieved in 5 min. Use of inhibitors of the proton motive force revealed that transport of norfloxacin was energy independent. Thus, the same mechanisms of quinolone accumulation that occur in eubacteria seem to occur in mycobacteria, at least in M. smegmatis. PMID:8585727

    Newspaper pulp was found to be a potential adsorbent for removal of copper from aqueous medium. Detail adsorption study of Cu on newspaper pulp was investigated. Batch adsorption study was carried out as a function of contact time, adsorbent dose, temperature (303-323 K). The experimental data was analyzed using Freundlich, Langmuir, Dubinin-Radushkevich (D-R) and Redlich-Peterson (R-P) isotherm models. It was found that Freundlich, Langmuir and R-P models fitted well. pH variation study revealed that the adsorption increased with increase in pH of the solution. Maximum loading capacity was found to be 30 mg g -1 at 20 mg L -1 of initial Cu concentration. Adsorption data were analyzed using two kinetic models, Lagergren first order and pseudo second order. It was observed that pseudo second order represented the best correlation. Langmuir isotherm was used to obtain the thermodynamic parameters such as free energy (ΔG o ), enthalpy (ΔH o ) and entropy (ΔS o ) of adsorption. The negative value of free energy and positive value of enthalpy change indicate that the adsorption of Cu on newspaper pulp is a spontaneous process and endothermic. The results of activation energy also confirmed that the adsorption of Cu on newspaper pulp is physical in nature. Present investigation emphasized that newspaper pulp may be utilized as a low cost adsorbent for copper removal

    Weyl-orbit functions have been defined for each simple Lie algebra, and permit Fourier-like analysis on the fundamental region of the corresponding affine Weyl group. They have also been discretized, using a refinement of the coweight lattice, so that digitized data on the fundamental region can be Fourier-analyzed. The discretized orbit function has arguments that are redundant if related by the affine Weyl group, while its labels, the Weyl-orbit representatives, invoke the dual affine Weyl group. Here we discretize the orbit functions in a novel way, by using the weight lattice. A cleaner theory results with symmetry between the arguments and labels of the discretized orbit functions. Orthogonality of the new discretized orbit functions is proved, and leads to the construction of unitary, symmetric matrices with Weyl-orbit-valued elements. For one type of orbit function, the matrix coincides with the Kac-Peterson modular S matrix, important for Wess-Zumino-Novikov-Witten conformal field theory.

    An adult Pacific lamprey (Lampetra tridentata) escapement estimate was generated in the lower Deschutes River during run year 2008. This included a mark-recapture study to determine adult abundance and a tribal subsistence creel. Fish measuring less than 10.5 cm received two marks for the mark-recapture estimate while those measuring greater than 10.5 cm were surgically implanted with radio transmitters to monitor migration upstream of Sherars Falls (rkm 70.4). Radio telemetry was used to determine habitat, focal spawning areas and spawn timing. All fish were collected at the Sherars Falls fish ladder from July-October 2008 using a long handled dip-net. Escapement was generated using a two event mark-recapture experiment. Adult lamprey populations were estimated at 3,471 (95% CI = 2,384-5,041; M = 101; C = 885 R = 25) using Chapman's modification of the Peterson estimate. The relative precision around the estimate was 31.42. Tribal harvest was approximately 806 adult lamprey (95% CI = +/- 74) with a total escapement of 2,669. Fourteen lamprey received radio tags and were released at Lower Blue Hole recreation site (rkm 77.3). Movement was recorded by mobile, fixed site and aerial telemetry methods. Upstream movements of lamprey were documented from July through December 2008 with most lamprey over-wintering in the mainstem Deschutes River.

    Full Text Available Chitosan is a natural polymer that has been employed in dye adsorption. In this work, adsorption and thermodynamic data for the interaction of FD&C Red n° 40 food dye with chitosan in aqueous solutions were investigated. The equilibrium adsorption isotherms were determined by the batch method, from 298 to 338 K. Adsorption data were adjusted to five isotherm models: Langmuir, Freundlich, Redlich-Peterson, Temkin and Dubinin-Radushkevich, in order to determine which presented the best adjustment to the experimental data. Error analysis showed that the Langmuir isotherm model was the most appropriate for fitting the experimental data, with a maximum monolayer adsorption of 3065.8 µmol g-1 at 308 K. Negative enthalpy (-112.7 kJ mol-1, entropy (-0.338 kJ mol-1 K-1 and Gibbs free energy (-15.6 to 1.0 kJ mol-1 values demonstrated that the adsorption process is exothermic, spontaneous, favorable, and that randomness of the system decreases during the adsorption process.

    During the years 1994-97, the emulsion target of the CHORUS detector was exposed to the wideband neutrino beam of the CERN SPS. In total about 100 000 charged-current neutrino interactions were located in the nuclear emulsion target and fully reconstructed. From this sample of events which was based on the data acquired by new automatic scanning systems, 1048 D0 events were selected by a pattern recognition program. They were confirmed as neutral-particle decays through visual inspection. Fragmentation properties of deep-inelastic charm production were measured using these events. Distributions of the D0 momentum, Feynman x(x_F), z and tan thetaôut, the transverse angle out of the leptonic plane defined by the muon and the neutrino, are presented. The mean value of z was measured to be (z) = 0.63 +- 0.03(stat) +- 0.01(syst). From fits to the z distribution, values for the Peterson parameter epsilon_p = 0.108 +- 0.017(stat) +- 0.013(syst) and the Collins-Spiller parameter epsilon_CS = 0.21^+0.05_-0.04(stat) +...

  17. Preparation of mesoporous poly (acrylic acid)/SiO2 composite nanofiber membranes having adsorption capacity for indigo carmine dye (United States)

    Xu, Ran; Jia, Min; Li, Fengting; Wang, Hongtao; Zhang, Bingru; Qiao, Junlian


    Mesoporous poly (acrylic acid)/SiO2 (PAA/SiO2) composite nanofiber membranes functionalized with mercapto groups were fabricated by a sol-gel electrospinning method, and their adsorption capacity for indigo carmine was investigated. The membranes were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, x-ray powder diffraction (XRD), and nitrogen adsorption-desorption measurement. SEM and TEM observation results showed that the PAA/SiO2 fibers had diameters between 400-800 nm and mesopores with an average pore size of 3.88 nm. The specific surface area of the mesoporous nanofiber membranes was 514.89 m2/g. The characteristic peaks for mercapto group vibration in FTIR and Raman spectra demonstrated that the mercapto groups have been incorporated into the silica skeleton. The adsorption isotherm data of indigo carmine on the membranes fit well with Redlich-Peterson model, and the maximum adsorption capacity calculated was 523.11 mg/g. It was found that the removal rate of indigo carmine by the membranes reached a maximum of 98% in 90 min and the adsorption kinetics followed a pseudo-second-order model. The high adsorption capacity of PAA/SiO2 nanofiber membrane makes it a promising adsorbent for indigo carmine removal from the wastewater.

  18. Rice husk ash as an effective adsorbent: evaluation of adsorptive characteristics for Indigo Carmine dye. (United States)

    Lakshmi, Uma R; Srivastava, Vimal Chandra; Mall, Indra Deo; Lataye, Dilip H


    Present study explored the adsorptive characteristics of Indigo Carmine (IC) dye from aqueous solution onto rice husk ash (RHA). Batch experiments were carried out to determine the influence of parameters like initial pH (pH(0)), contact time (t), adsorbent dose (m) and initial concentration (C(0)) on the removal of IC. The optimum conditions were found to be: pH(0)=5.4, t=8h and m=10.0 g/l. The pseudo-second-order kinetic model represented the adsorption kinetics of IC on to RHA. Equilibrium isotherms were analyzed by Freundlich, Langmuir, Temkin and Redlich-Peterson models using a non-linear regression technique. Adsorption of IC on RHA was favorably influenced by an increase in the temperature of the operation. The positive values of the change in entropy (DeltaS(0)) and heat of adsorption (DeltaH(0)); and the negative value of change in Gibbs free energy (DeltaG(0)) indicate feasible and spontaneous adsorption of IC on to RHA.

  19. The self-concept of chiropractic students as science students (United States)

    Shields, Robert F.


    Abstract Purpose To determine the self-concepts of chiropractic students as science students and if any personal variable affect their self-concepts. Participants Students in their first trimester and eighth trimester at the Los Angeles College of Chiropractic during the 1993 academic year (n=158). Methods Peterson-Yaakobi Q-Sort, National Assessment of Educational Progress, two-tailed T-test, one way analysis of variance and Spearman-rho correlation. Results The majority of students have positive self- concepts as science students and although there was a difference between the 2 trimesters, it was not significant. As a group they generally had less exposure to science compared to undergraduates from a selected science program. Variables of socio-economic status, undergraduate major, and highest completed level of education did not statistically affect their self-concept. Conclusion Chiropractic students had the self-concept that enables them to subscribe to the philosophical foundations of science and better engage in basic sciences and, later, science-based clinical research. Knowledge of this self- concept can be used in the development of a more rigorous basic science curricula and clinical research programs at chiropractic colleges with the ultimate goal of providing a more firm scientifically based foundation for the profession.

  20. Research note: effect of tetracycline hydrochloride and oxytetracycline hydrochloride given via drinking water on early mortality of broiler chicks from twenty-eight-week-old dams. (United States)

    Peterson, R A; Carpenter, G H; Jones, W T; Kula, J A


    The effect of tetracycline HCl and oxytetracycline HCl on early mortality in straight-run Peterson x Hubbard cross broiler chicks from 28-wk-old dams was studied. Treatments consisted of a sham-treated control, and groups treated with a tetracycline either HCl (25 mg/454 g of BW per day) or an oxytetracycline HCl (14.6 mg/454 g of BW per day). Each group was treated via the drinking water for the first 5 days after hatching. There were 24 replications per treatment with 54 chicks each. Birds were maintained at a density of 622.5 cm2 per chick. Chicks treated with tetracycline HCl and oxytetracycline HCl had significantly (P less than .05) improved livability when compared with the sham-treated controls both at 2 and 6 wk of age (1.00 and .83 versus 1.79 at 2 wk, and 2.79 and 3.29 versus 4.29% mortality at 6 wk, respectively). No significant differences in mortality were observed between tetracycline HCl-treated chicks and oxytetracycline HCl-treated chicks. At the end of the 6-wk trial, no differences between treatments were seen in the productive performance of the broilers. The observed differences in livability at 6 wk of age could increase the number of saleable broilers by 10 to 15 thousand per million chicks placed.
