  1. Assaying J. L. Mackie\\\\\\'s View on Evil Based on Suhrewardi\\\\\\'s Philosophy

    Directory of Open Access Journals (Sweden)

    S.Moreza Hosseini Shahroudi


    Full Text Available J. L. Mackie is among those philosophers who have highlighted evil as evidence to God's nonexistence. Suhrewardi's ideas of evil can partially answer some of his critiques. There are two kinds of answers to Mackie's objections in Suhrewardi's ideas: 1- direct answers, 2- answers which can be inferred from the general principles of Suhrewardi's philosophy. Of course some of Mackie's critiques cannot be retorted upon Suhrewardi's philosophy.   J. L. Mackie lays out his major objection through the argument that God is omnipotent, he is purely good, evil exists; the latter proposition shall contradict the former two ones if they are true. Following this argument Mackie levels other minor objections too.   The major objection of Mackie can be retorted by basic principles of Suhrewardi's philosophy: human lack of authority in attribution of good and evil a principle which if adopted by one it eventually leads to partial evil's disappearance in universal goodness; acceptance of the rule: "the higher is not concerned with the lower" which disqualifies man of negation of absolute divine attributes after the demonstration of Necessary Being; rational determination of taxonomy of contingent beings according to the good/evil order the result of which is demonstration of pure goodness of God and minor evil's not being in contradiction with pure goodness attribute; acceptance of the maxim that evils are necessary for higher goods which not only makes evils' existence not to challenge divine power and goodness but rather it is indeed the lack of evil that would challenge wisdom.    Having outlined his major critique, Mackie reviews some of the answers offered by the theosophers and then takes them all to task.   The first contradictory solution discussed by Mackie reads "good cannot exist without evil, or stated otherwise, evil is necessarily associated with good". Mackie levels some critiques against this solution. Among others one of these critiques is

  4. On the notion of causality in medicine: addressing Austin Bradford Hill and John L. Mackie

    Directory of Open Access Journals (Sweden)

    Luís Fernando S. C. de Araújo


    Full Text Available Almost 50 years ago appeared the seminal article by Austin Bradford Hill where he presented parameters for inferring causes from statistical associations, which became known as Hill’s causal criteria. This was a milestone for the renewal of the idea of cause in medicine. Our article revisits his contribution in light of the ideas from the Australian philosopher John L. Mackie, whose important works on causality reached an audience distinct from Hill’s. We suggest that both the British epidemiologist and the Australian philosopher share the purpose of articulating probabilistic determinism and multi-causality, the first with a predominantly probabilistic model and the second with an analytical approach. This article explores the possible consequences of addressing these authors jointly in regard to causal inferences in medicine, especially in respect to mental disorders.

  5. Virasoro central charges for Nichols algebras

    CERN Document Server

    Semikhatov, A M


    Virasoro central charge associated with Nichols algebras is invariant under the Weyl groupoid action and takes very suggestive values for some items in Heckenberger's list of rank-2 Nichols algebras. In particular, this might be taken as an indication of the existence of reasonable logarithmic extensions of W3==WA2, WB2, and WG2 models of conformal field theory. In the W3 case, the construction of an octuplet extended algebra is outlined.

  6. Modal Processor Effects Inspired by Hammond Tonewheel Organs

    Directory of Open Access Journals (Sweden)

    Kurt James Werner


    Full Text Available In this design study, we introduce a novel class of digital audio effects that extend the recently introduced modal processor approach to artificial reverberation and effects processing. These pitch and distortion processing effects mimic the design and sonics of a classic additive-synthesis-based electromechanical musical instrument, the Hammond tonewheel organ. As a reverb effect, the modal processor simulates a room response as the sum of resonant filter responses. This architecture provides precise, interactive control over the frequency, damping, and complex amplitude of each mode. Into this framework, we introduce two types of processing effects: pitch effects inspired by the Hammond organ’s equal tempered “tonewheels”, “drawbar” tone controls, vibrato/chorus circuit, and distortion effects inspired by the pseudo-sinusoidal shape of its tonewheels and electromagnetic pickup distortion. The result is an effects processor that imprints the Hammond organ’s sonics onto any audio input.

  7. On Nichols algebras associated to simple racks

    CERN Document Server

    Andruskiewitsch, N; Garcia, G A; Vendramin, L


    This is a report on the present state of the problem of determining the dimension of the Nichols algebra associated to a rack and a cocycle. This is relevant for the classification of finite-dimensional complex pointed Hopf algebras whose group of group-likes is non-abelian. We deal mainly with simple racks. We recall the notion of rack of type D, collect the known lists of simple racks of type D and include preliminary results for the open cases. This notion is important because the Nichols algebra associated to a rack of type D and any cocycle has infinite dimension. For those racks not of type D, the computation of the cohomology groups is needed. We discuss some techniques for this problem and compute explicitly the cohomology groups corresponding to some conjugacy classes in symmetric or alternating groups of low order.

  9. "Lesbians are not women": feminine and lesbian sensibilities in Harmony Hammond's late-1970s sculpture. (United States)

    Thompson, Margo Hobbs


    Harmony Hammond's wrapped fabric sculptures are placed in context of the theories of gender and sexuality that circulated among lesbian and straight feminists at the time they were made, the late 1970s. Hammond has cited in particular Monique Wittig's novels, such as The Lesbian Body, and her essays including "The Straight Mind" where Wittig concludes that the lesbian is not a woman. The critique to which Wittig's lesbian separatism has been subjected by Judith Butler in her consideration of the appeal and limitations of essentialism also applies to Hammond's art. Hammond's use of vaginal imagery was instrumental to visualizing a lesbian sensibility, but the proposition of such a sensibility established a new problematic: a new essential category. The article concludes that because Hammond's work was produced in the context of a complex set of discourses, lesbian, feminist, and aesthetic, it resisted reduction to a singular meaning. Her sculptures avoided the pitfall of substituting one essence for another, lesbian for feminine sensibility, but activated both. The sculptures effectively queered vaginal imagery: When Hammond used vaginal imagery to represent lesbian sensibility, she subverted the equation of sex and gender and the essentialist notion of feminine sensibility.

  15. Quantum Mechanics in Chemistry (by Jack Simons and Jeff Nichols) (United States)

    McCallum, C. Michael


    Topics in Physical Chemistry Series. Oxford University Press: New York, 1997. xxiii + 612 pp. Illustrations. ISBN 0-19-508200-1. $75.00. One of the problems faced by graduate-level quantum mechanics courses in chemistry is that there is often little time for studying chemical problems. Students must learn so much matrix algebra and notation that a first-semester course seems more like a math or physics course than chemistry. Another problem is the focus of most graduate texts. Excellent texts, such as those by Sakurai, and older treatments, such as Messiah and Cohen-Tannoudji, offer a comprehensive amount of mathematical rigor to go along with chemistry problems, but it seems the intended audience is hard-core theoretical or physical chemistry students. Requirements that are more general, such as reaction-path dynamics, structure and term symbols, and symmetry in quantum mechanical problems, are often left behind. Schatz and Ratner's Book Quantum Mechanics in Chemistry (Prentice Hall) is one book that fills this gap (at least for second-semester students); Simons and Nichols' new book is another, but it is a book that requires revision before it can be seriously considered.

  16. Options for managing the sustainable use of green turtles: Perceptions of Hammond Islanders in Torres Strait

    Directory of Open Access Journals (Sweden)

    Grayson Jillian


    Full Text Available One of the largest populations of green turtles (Chelonia mydas in the world spends at least part of its life cycle in the remote Torres Strait between Australia and Papua New Guinea. This population is subjected to traditional harvests from geographically dispersed communities including along the northern and eastern coasts of Australia, Indonesia and south-western Pacific nations. In Torres Strait, green turtle hunting is classed as a traditional fishery and is guaranteed by Australian legislation (Native Title Act 1993 and the Torres Strait Treaty between Australia and Papua New Guinea that aims to protect the traditional lifestyle of the region′s indigenous peoples. To investigate the Islanders′ thoughts and aspirations regarding marine turtle management, we interviewed hunters and Islander Elders from the Hammond Island community in the Kaurareg nation of Kaiwalagal. Although not the Traditional Owners of the Kaiwalagal sea country in which they live and hunt, Hammond Islanders wish to be involved in the management of resources on which they depend, including marine turtles. They considered community-based processes to be important, especially the application of (1 cultural norms to the development of tools to achieve compliance and enforcement within the community, and (2 consensus-based decision-making amongst hunters and elders within the community, with regard to the use of more formal rules. However, the need for co-operation with other communities and stakeholders across scales was also recognised, particularly with regard to enforcement. Our results suggest that co-management is likely to be a more appropriate approach for managing green turtles in Torres Strait than either community-based management or government-driven management.

  17. Genome differences between Treponema pallidum subsp. pallidum strain Nichols and T. paraluiscuniculi strain Cuniculi A. (United States)

    Strouhal, Michal; Smajs, David; Matejková, Petra; Sodergren, Erica; Amin, Anita G; Howell, Jerrilyn K; Norris, Steven J; Weinstock, George M


    The genome of Treponema paraluiscuniculi strain Cuniculi A was compared to the genome of the syphilis spirochete Treponema pallidum subsp. pallidum strain Nichols using DNA microarray hybridization, whole-genome fingerprinting, and DNA sequencing. A DNA microarray of T. pallidum subsp. pallidum Nichols containing all 1,039 predicted open reading frame PCR products was used to identify deletions and major sequence changes in the Cuniculi A genome. Using these approaches, deletions, insertions, and prominent sequence changes were found in 38 gene homologs and six intergenic regions of the Cuniculi A genome when it was compared to the genome of T. pallidum subsp. pallidum Nichols. Most of the observed differences were localized in tpr loci and the vicinity of these loci. In addition, 14 other genes were found to contain frameshift mutations resulting in major changes in protein sequences. Analysis of restriction target sites representing 0.34% of the total genome length and DNA sequencing of three PCR products (0.46% of the total genome length) amplified from Cuniculi A chromosomal regions and comparison to the Nichols genome revealed a sequence similarity of 98.6 to 99.3%. These results are consistent with a close genetic relationship among the T. pallidum strains and subspecies and a strong, but relatively divergent connection between the human and rabbit pathogens.

  18. Comparative Reaction Diagrams for the SN2 Reaction Formulated According to the Leffler Analysis and the Hammond Postulate. (United States)

    Haddon, Robert C; Tian, Ziqi; Jiang, De-En


    The Hammond Postulate and the Leffler analysis have provided a cornerstone in the understanding of reaction processes in organic chemistry for over 60 years, yet quantitative applications of these methodologies over the range of reactions envisaged in the original works remain elusive. In the present paper, we analyze a series of SN2 reactions in three solvents that lead to endothermic and exothermic reaction processes, and we show that within the hybridization reaction coordinate the SN2 reaction is fully consistent with both treatments. We give new presentations of the reaction energies as a function of reaction progress, which allow the generation of unified reaction coordinate diagrams that show a linear relationship between the hybridization metric of reaction progress and the relative energies of the stationary points on the potential surface as a function of structure and solvent as originally envisaged by Leffler and Hammond.

  20. A Challenging Time in the History of Lamaze International: An Interview With Francine Nichols (United States)

    Zwelling, Elaine


    Dr. Francine Nichols—President of Lamaze International from 1988 to 1991 (when the organization was known as “the American Society for Psychoprophylaxis in Obstetrics” or “ASPO/Lamaze”) and the founding editor of The Journal of Perinatal Education in 1990—is a woman with many skills that have contributed to her success throughout her career. Dr. Nichols is a knowledgeable leader in maternal-newborn nursing, a respected nurse and childbirth educator, a researcher, and an author. However, these skills were not the abilities she relied upon the most to lead the Lamaze organization through a challenging period in the 1980s; rather, Dr. Nichols's tenacity, business savvy, and willingness to face controversy helped guide Lamaze International back on track so that it was able to grow into the strong organization it remains today. This interview took place by telephone on June 12, 2006, when Dr. Nichols was in Washington, D.C., for the summer to coordinate the National Institute of Nursing Research's Summer Genetics Institute, a doctoral-level course cosponsored by Georgetown University.

  1. Beyond face validity - A comment on Nicholls, Licht, and Pearl. [gender-related personality traits (United States)

    Spence, Janet T.; Helmreich, Robert L.


    In their discussion of the Bem Sex Role Inventory (BSRI; Bem, 1974) and the Personal Attributes Questionnaire (PAQ; Spence and Helmrich, 1978), Nicholls, et al. (1982) blur two issues. The first concerns the legitimacy of equating the clusters of gender-related personality traits tapped by these instruments with the global constructs of masculinity and feminity. The second concerns item similarity between the PAQ and BSRI M scales and measures of self-esteem and the question of whether the several instruments measure the same or separable constructs. Decisions about each of these issues involve complex considerations that do not directly involve face validity.

  2. Resequencing of Treponema pallidum ssp. pallidum strains Nichols and SS14: correction of sequencing errors resulted in increased separation of syphilis treponeme subclusters.

    Directory of Open Access Journals (Sweden)

    Helena Pětrošová

    Full Text Available BACKGROUND: Treponema pallidum ssp. pallidum (TPA, the causative agent of syphilis, is a highly clonal bacterium showing minimal genetic variability in the genome sequence of individual strains. Nevertheless, genetically characterized syphilis strains can be clearly divided into two groups, Nichols-like strains and SS14-like strains. TPA Nichols and SS14 strains were completely sequenced in 1998 and 2008, respectively. Since publication of their complete genome sequences, a number of sequencing errors in each genome have been reported. Therefore, we have resequenced TPA Nichols and SS14 strains using next-generation sequencing techniques. METHODOLOGY/PRINCIPAL FINDINGS: The genomes of TPA strains Nichols and SS14 were resequenced using the 454 and Illumina sequencing methods that have a combined average coverage higher than 90x. In the TPA strain Nichols genome, 134 errors were identified (25 substitutions and 109 indels, and 102 of them affected protein sequences. In the TPA SS14 genome, a total of 191 errors were identified (85 substitutions and 106 indels and 136 of them affected protein sequences. A set of new intrastrain heterogenic regions in the TPA SS14 genome were identified including the tprD gene, where both tprD and tprD2 alleles were found. The resequenced genomes of both TPA Nichols and SS14 strains clustered more closely with related strains (i.e. strains belonging to same syphilis treponeme subcluster. At the same time, groups of Nichols-like and SS14-like strains were found to be more distantly related. CONCLUSION/SIGNIFICANCE: We identified errors in 11.5% of all annotated genes and, after correction, we found a significant impact on the predicted proteomes of both Nichols and SS14 strains. Corrections of these errors resulted in protein elongations, truncations, fusions and indels in more than 11% of all annotated proteins. Moreover, it became more evident that syphilis is caused by treponemes belonging to two separate genetic

  3. A Simple Attitude Control of Quadrotor Helicopter Based on Ziegler-Nichols Rules for Tuning PD Parameters

    Directory of Open Access Journals (Sweden)

    ZeFang He


    Full Text Available An attitude control strategy based on Ziegler-Nichols rules for tuning PD (proportional-derivative parameters of quadrotor helicopters is presented to solve the problem that quadrotor tends to be instable. This problem is caused by the narrow definition domain of attitude angles of quadrotor helicopters. The proposed controller is nonlinear and consists of a linear part and a nonlinear part. The linear part is a PD controller with PD parameters tuned by Ziegler-Nichols rules and acts on the quadrotor decoupled linear system after feedback linearization; the nonlinear part is a feedback linearization item which converts a nonlinear system into a linear system. It can be seen from the simulation results that the attitude controller proposed in this paper is highly robust, and its control effect is better than the other two nonlinear controllers. The nonlinear parts of the other two nonlinear controllers are the same as the attitude controller proposed in this paper. The linear part involves a PID (proportional-integral-derivative controller with the PID controller parameters tuned by Ziegler-Nichols rules and a PD controller with the PD controller parameters tuned by GA (genetic algorithms. Moreover, this attitude controller is simple and easy to implement.

  8. Syphilis-causing strains belong to separate SS14-like or Nichols-like groups as defined by multilocus analysis of 19 Treponema pallidum strains. (United States)

    Treponema pallidum strains are closely related at the genome level but cause distinct diseases. Subspecies pallidum (TPA) is the causative agent of syphilis, subspecies pertenue (TPE) causes yaws while subspecies endemicum (TEN) causes bejel (endemic syphilis). Compared to the majority of treponemal genomic regions, several chromosomal loci were found to be more diverse. To assess genetic variability in diverse genomic positions, we have selected (based on published genomic data) and sequenced five variable loci, TP0304, TP0346, TP0488, TP0515 and TP0558, in 19 reference Treponema pallidum strains including all T. pallidum subspecies (TPA, TPE and TEN). Results of this multilocus analysis divided syphilitic isolates into two groups: SS14-like and Nichols-like. The SS14-like group is comprised of SS14, Grady, Mexico A and Philadelphia 1 strains. The Nichols-like group consisted of strains Nichols, Bal 73-1, DAL-1, MN-3, Philadelphia 2, Haiti B and Madras. The TP0558 locus was selected for further studies because it clearly distinguished between the SS14- and Nichols-like groups and because the phylogenetic tree derived from the TP0558 locus showed the same clustering pattern as the tree constructed from whole genome sequences. In addition, TP0558 was shown as the only tested locus that evolved under negative selection within TPA strains. Sequencing of a short fragment (573bp) of the TP0558 locus in a set of 25 clinical isolates from 22 patients collected in the Czech Republic during 2012-2013 revealed that clinical isolates follow the SS14- and Nichols-like distribution.

  9. Molecular typing of Treponema pallidum isolates from Buenos Aires, Argentina: Frequent Nichols-like isolates and low levels of macrolide resistance (United States)

    Gallo Vaulet, Lucía; Grillová, Linda; Mikalová, Lenka; Casco, Ricardo; Rodríguez Fermepin, Marcelo; Pando, María A.; Šmajs, David


    A total of 54 clinical samples, including genital lesion swabs, whole blood and cerebrospinal fluid from patients diagnosed with syphilis were collected in 2006 and in 2013 in Buenos Aires, Argentina. Treponemal DNA was detected in 43 of the analyzed samples (79.6%) and further analyzed using Sequencing-based molecular typing (SBMT) and Enhanced CDC-typing (ECDCT). By SBMT, 10 different Treponema pallidum subsp. pallidum (TPA) genotypes were found, of which six were related to the TPA SS14 strain, and four to the TPA Nichols strain. The 23S rRNA gene was amplified in samples isolated from 42 patients, and in six of them (14.3%), either the A2058G (four patients, 9.5%) or the A2059G (two patients, 4.8%) mutations were found. In addition to Taiwan, Madagascar and Peru, Argentina is another country where the prevalence of Nichols-like isolates (26.8%) is greater than 10%. PMID:28235102

  10. The MMPI-2/MMPI-2-RF Symptom Validity Scale (FBS/FBS-r) is not a measure of 'litigation response syndrome': commentary on Nichols and Gass (2015). (United States)

    Larrabee, Glenn J; Bianchini, Kevin J; Boone, Kyle B; Rohling, Martin L


    To address (1) Whether there is empirical evidence for the contention of Nichols and Gass that the MMPI-2/MMPI-2-RF FBS/FBS-r Symptom Validity Scale is a measure of Litigation Response Syndrome (LRS), representing a credible set of responses and reactions of claimants to the experience of being in litigation, rather than a measure of non-credible symptom report, as the scale is typically used; and (2) to address their stated concerns about the validity of FBS/FBS-r meta-analytic results, and the risk of false positive elevations in persons with bona-fide medical conditions. Review of published literature on the FBS/FBS-r, focusing in particular on associations between scores on this symptom validity test and scores on performance validity tests (PVTs), and FBS/FBS-r score elevations in patients with genuine neurologic, psychiatric and medical problems. (1) several investigations show significant associations between FBS/FBS-r scores and PVTs measuring non-credible performance; (2) litigants who pass PVTs do not produce significant elevations on FBS/FBS-r; (3) non-litigating medical patients (bariatric surgery candidates, persons with sleep disorders, and patients with severe traumatic brain injury) who have multiple physical, emotional and cognitive symptoms do not produce significant elevations on FBS/FBS-r. Two meta-analytic studies show large effect sizes for FBS/FBS-r of similar magnitude. FBS/FBS-r measures non-credible symptom report rather than legitimate experience of litigation stress. Importantly, the absence of significant FBS/FBS-r elevations in litigants who pass PVTs demonstrating credible performance, directly contradicts the contention of Nichols and Gass that the scale measures LRS. These data, meta-analytic publications, and recent test use surveys support the admissibility of FBS/FBS-r under both Daubert and the older Frye criteria.

  11. Restoring Anadromous Fish Habitat in Big Canyon Creek Watershed; Anadromous Fish Habitat Restoration in the Nichols Canyon Subwatershed, 2001 Annual Report.

    Energy Technology Data Exchange (ETDEWEB)

    Koziol, Deb (Nez Perce Soil and Water Conservation District, Lewiston, ID)


    Big Canyon Creek historically provided quality spawning and rearing habitat for A-run wild summer steelhead in the Clearwater River subbasin (Fuller, 1986). However, high stream temperatures, excessive sediment and nutrient loads, low summer stream flows, and little instream cover caused anadromous fish habitat constraints in the creek. The primary sources of these nonpoint source pollution and habitat degradations are attributed to agricultural, livestock, and forestry practices (NPSWCD, 1995). Addressing these problems is made more complex due to the large percentage of privately owned lands in the watershed. Nez Perce Soil and Water Conservation District (NPSWCD) seeks to assist private, tribal, county, and state landowners in implementing Best Management Practices (BMPs) to reduce nonpoint source pollutants, repair poorly functioning riparian zones, and increase water retention in the Nichols Canyon subwatershed. The project funds coordination, planning, technical assistance, BMP design and installation, monitoring, and educational outreach to identify and correct problems associated with agricultural and livestock activities impacting water quality and salmonid survival. The project accelerates implementation of the Idaho agricultural water quality management program within the subwatershed.

  1. Geographical patterns of parasite infracommunities in the rough scad, Trachurus lathami Nichols, in the Southwestern Atlantic ocean. (United States)

    Braicovich, Paola E; Luque, José L; Timi, Juan T


    We assessed temporal variability in parasite infections of rough scad (Trachurus lathami) in 3 samples from Miramar (MI) in 2008, separated by periods of 1 mo, and 2 samples from Villa Gesell (VG), 1 each in 2008 and 2009 (Buenos Aires Province, Argentina), respectively. A sample was also obtained from Cabo Frio (CF) (Brazil) in 2009 to compare differences in parasite communities between fish from this locality and each Argentinean locality. All rough scad were parasitized by at least 1 of 27 parasite species. Similarity-based multivariate analysis revealed significant differences between localities, but temporal homogeneity in each Argentinean locality. Overall, prevalence and abundance of parasite species were most similar between samples from MI and VG, while the greatest differences occurred between samples from MI and CF. A canonical analysis of principal coordinates showed significant differences among samples. Grillotia carvajalregorum was the most important species in determining the position of Argentinean samples, especially those from MI, while Ectenurus virgulus , Raphidascaris sp., and Hysterothylacium sp. were the most important species related to fish from CF. The parasite assemblage of T. lathami showed a notable temporal persistence within the same locality and a high variability at the spatial scale, suggesting the existence of 3 independent stocks of T. lathami in South Atlantic waters.

De acordo com os conceitos da Cronobiologia foi levantada a hipótese de ritmo circadiano na atividade alimentar, provavelmente sincronizado pelo ciclo claro/escuro.

  3. Influence of the temperature on the early larval development of the Pacific red snapper, Lutjanus peru (Nichols & Murphy, 1922

    Directory of Open Access Journals (Sweden)

    José Antonio Estrada-Godínez


    Full Text Available The Pacific red snapper, Lutjanus peru, is a commercially important species throughout its distribution range, making it a good alternative for aquaculture; however, there is few information regarding environmental conditions and their influence on early development of this species. Temperature is one of the main factors affecting embryo and larval development in marine fishes. In this paper, the effects of different temperatures upon hatching rate, growth, consumption of yolk sac and oil droplet and the formation of the digestive system and eye pigmentation were evaluated in larvae of this species under experimental conditions. Eggs incubated between 20 and 32°C showed hatching rates higher than 90%. However, larvae maintained at 26°C showed significantly larger notochord length and were the first to complete the pigmentation of the eyes and the formation of the digestive system when still possessing enough reserves in the yolk sac. Therefore, according to the results obtained, it is recommended that the incubation of eggs and larval rearing in Pacific red snapper takes place between 25 and 26°C.

  9. Theories of truth as assessment criteria in judgment and decision making

    Directory of Open Access Journals (Sweden)

    Philip T. Dunwoody


    Full Text Available Hammond (1996 argued that much of the research in the field of judgment and decision making (JDM can be categorized as focused on either coherence or correspondence (CandC and that, in order to understand the findings of the field, one needs to understand the differences between these two criteria. extit{Hammond's claim} is that conclusions about the competence of judgments and decisions will depend upon the selection of coherence or correspondence as the criterion (Hammond, 2008. First, I provide an overview of the terms coherence and correspondence (CandC as philosophical theories of truth and relate them to the field of JDM. Second, I provide an example of Hammond's claim by examining literature on base rate neglect. Third, I examine Hammond's claim as it applies to the broader field of JDM. Fourth, I critique Hammond's claim and suggest that refinements to the CandC distinction are needed. Specifically, the CandC distinction 1 is more accurately applied to criteria than to researchers, 2 should be refined to include two important types of coherence (inter and intrapersonal coherence and 3 neglects the third philosophical theory of truth, pragmatism. Pragmatism, as a class of criteria in JDM, is defined as goal attainment. In order to provide the most complete assessment of human judgment possible, and understand different findings in the field of JDM, all three criteria should be considered.

  10. Must Metaethical Realism Make a Semantic Claim? (United States)

    Kahane, Guy


    Mackie drew attention to the distinct semantic and metaphysical claims made by meta ethical realists, arguing that although our evaluative discourse is cognitive and objective, there are no objective evaluative facts. This distinction, however, also opens up a reverse possibility: that our evaluative discourse is antirealist, yet objective values do exist. I suggest that this seemingly far-fetched possibility merits serious attention; realism seems com mitted to its intelligibility, and, despite appearances, it isn't incoherent, ineffable, inherently implausible or impossible to defend. I argue that reflection on this possibility should lead us to revise our understanding of the debate between realists and antirealists. It is not only that the realist's semantic claim is insufficient for realism to be true, as Mackie argued; it's not even necessary. Robust metaethical realism is best understood as making a purely metaphysical claim. It is thus not enough for antirealists to show that our discourse is antirealist. They must directly attack the realist's metaphysical claim.

    The paper is an analysis of two-positions (hysteresis) regulators, self-tuned PID controller and PID controller for temperature control used for indirect heat resistance furnaces. For PID controller was used three methods of tuning: Ziegler-Nichols step response model, Cohen-Coon tuning rules and Ziegler-Nichols tuning rules. In experiments it used an electric furnace with indirect heating with active power of resistance of 1 kW/230V AC and a numerical temperature regulator AT-503 type (ANLY). It got a much better temperature control when using the Cohen-Coon tuning rules method than those of Ziegler-Nichols step response method and Ziegler-Nichols tuning rules method.

  10. Footprint of positive selection in Treponema pallidum subsp. pallidum genome sequences suggests adaptive microevolution of the syphilis pathogen. (United States)

    Giacani, Lorenzo; Chattopadhyay, Sujay; Centurion-Lara, Arturo; Jeffrey, Brendan M; Le, Hoavan T; Molini, Barbara J; Lukehart, Sheila A; Sokurenko, Evgeni V; Rockey, Daniel D


    In the rabbit model of syphilis, infection phenotypes associated with the Nichols and Chicago strains of Treponema pallidum (T. pallidum), though similar, are not identical. Between these strains, significant differences are found in expression of, and antibody responses to some candidate virulence factors, suggesting the existence of functional genetic differences between isolates. The Chicago strain genome was therefore sequenced and compared to the Nichols genome, available since 1998. Initial comparative analysis suggested the presence of 44 single nucleotide polymorphisms (SNPs), 103 small (≤3 nucleotides) indels, and 1 large (1204 bp) insertion in the Chicago genome with respect to the Nichols genome. To confirm the above findings, Sanger sequencing was performed on most loci carrying differences using DNA from Chicago and the Nichols strain used in the original T. pallidum genome project. A majority of the previously identified differences were found to be due to errors in the published Nichols genome, while the accuracy of the Chicago genome was confirmed. However, 20 SNPs were confirmed between the two genomes, and 16 (80.0%) were found in coding regions, with all being of non-synonymous nature, strongly indicating action of positive selection. Sequencing of 16 genomic loci harboring SNPs in 12 additional T. pallidum strains, (SS14, Bal 3, Bal 7, Bal 9, Sea 81-3, Sea 81-8, Sea 86-1, Sea 87-1, Mexico A, UW231B, UW236B, and UW249C), was used to identify "Chicago-" or "Nichols -specific" differences. All but one of the 16 SNPs were "Nichols-specific", with Chicago having identical sequences at these positions to almost all of the additional strains examined. These mutations could reflect differential adaptation of the Nichols strain to the rabbit host or pathoadaptive mutations acquired during human infection. Our findings indicate that SNPs among T. pallidum strains emerge under positive selection and, therefore, are likely to be functional in nature.

  19. An improved auto-tuning scheme for PI controllers. (United States)

    Mudi, Rajani K; Dey, Chanchal; Lee, Tsu-Tian


    Ziegler-Nichols tuned PI and PID controllers are usually found to provide poor performances for high-order and nonlinear systems. In this study, an improved auto-tuning scheme is presented for Ziegler-Nichols tuned PI controllers (ZNPICs). With a view to improving the transient response, the proportional and integral gains of the proposed controller are continuously modified based on the current process trend. The proposed controller is tested for a number of high-order linear and nonlinear dead-time processes under both set-point change and load disturbance. It exhibits significantly improved performance compared to ZNPIC, and Refined Ziegler-Nichols tuned PI controller (RZNPIC). Robustness of the proposed scheme is established by varying the controller parameters as well as the dead-time of the process under control.

  20. Action of μq(g) on Its Positive Part μq+(g)

    Institute of Scientific and Technical Information of China (English)

    Zhi Hua WANG; Li Bin LI


    In this paper,two kinds of skew derivations of a type of Nichols algebras are introduced,and then the relationship between them is investigated.In particular they satisfy the quantum Serre-relations.Therefore,the algebra generated by these derivations and corresponding automorphisms is a homomorphic image of the Drinfeld-Jimbo quantum enveloping algebra μq(g),which proves the Nichols algebra becomes aμq(g)-module algebra.But the Nichols algebra considered here is exactly μq+(g),namely,the positive part of the Drinfeld-Jimbo quantum enveloping algebra μq(g),it turns out that μq+(g)is a μq(g)-module algebra.

  1. Revision of Diplocirrus Haase, 1915, including Bradiella Rullier, 1965, and Diversibranchius Buzhinskaja, 1993 (Polychaeta, Flabelligeridae) (United States)

    Salazar-Vallejo, Sergio I.; Buzhinskaja, Galina


    Abstract Diplocirrus Haase, 1915, includes flabelligerids having cylindrical to club-shaped bodies, with cirriform papillae, multiarticulate chaetae in both parapodial rami, 8 branchial filaments of two types (thick and rarely lamellate, or cirriform), gonopodial lobes in chaetigers 5 or 6, or multiple gonopores along some anterior chaetigers. Bradiella Rullier, 1965, has included only the type species: Bradiella branchiata Rullier, 1965, described from Eastern Australia. The original description has been overlooked and it lacked enough details on branchial and chaetal features. Diversibranchius Buzhinskaja, 1993, with Diplocirrus nicolaji Buzhinskaja, 1994, as the type species, was introduced for a similar species from the Japan Sea. These two monotypic genera share the same morphologic features with Diplocirrus, and are herein regarded as its junior synonyms. As herein redefined, Diplocirrus includes, besides its type species, Diplocirrus glaucus (Malmgren, 1867)from Scandinavia : Diplocirrus branchiatus (Rullier, 1965), comb. n. from Queensland, Australia, Diplocirrus capensis Day, 1961 from South Africa, Diplocirrus erythroporus Gallardo, 1968 from Vietnam, Diplocirrus hirsutus (Hansen, 1882) from Arctic and subarctic regions, Diplocirrus incognitus Darbyshire & Mackie, 2009 from South Africa, Diplocirrus kudenovi sp. n. from off Western Mexico, Diplocirrus longisetosus (von Marenzeller, 1890) restricted to the Bering Sea, Diplocirrus micans Fauchald, 1972 from deep water off Oregon and Western Mexico, Diplocirrus nicolaji (Buzhinskaja, 1994), comb. n. from the Japan Sea, Diplocirrus normani (McIntosh, 1908), comb. n. from Scandinavia, Diplocirrus octobranchus (Hartman, 1965), comb. n. from off New England, and Diplocirrus stopbowitzi Darbyshire & Mackie, 2009 from the Irish Sea.

    Full Text Available A Composition control system is discussed in this paper in which the PID controller is tuned using Genetic Algorithm & Ziegler-Nichols Tuning Criteria. Tuning methods for PID controllers are very importantfor the process industries. Traditional methods such as Ziegler-Nichols method often do not provide adequate tuning. Genetic Algorithm (GA as an intelligent approach has also been widely used to tune the parameters of PID. Genetic algorithms are used to create an objective function that can evaluate the optimum PID gains based on the controlled systems overall error.

  3. On PID Controller Design Using Knowledge Based Fuzzy System

    Directory of Open Access Journals (Sweden)

    Jana Nowakova


    Full Text Available The designing of PID controllers is a frequently discussed problem. Many of design methods have been developed, classic (analytical tuning methods, optimization methods etc. or not so common fuzzy knowledge based methods which are designed to achieve good setpoint following, corresponding time response etc. In this case, the new way of designing PID controller parameters is created where the above mentioned knowledge system based on relations of Ziegler-Nichols design methods is used, more precisely the combination of the both Ziegler-Nichols methods. The proof of efficiency of a proposed method and a numerical experiment is presented.

    Nicholls, Michael E. R.; Loftus, Andrea M.; Orr, Catherine A.; Barre, Natalie


    Whereas right parietal damage can result in left hemineglect, the general population shows a subtle neglect of the right hemispace--known as pseudoneglect. A recent study has demonstrated that people collide to the right more often and attributed this bias to pseudoneglect. [Nicholls, M. E. R., Loftus, A., Meyer, K., & Mattingley, J.B. (2007).…

  5. Approximation of the Duffing oscillator frequency response function using the FPK equation

    Energy Technology Data Exchange (ETDEWEB)

    Cross, E J; Worden, K, E-mail: [Department of Mechanical Engineering, University of Sheffield, Mappin St Sheffield S1 3JD (United Kingdom)


    Although a great deal of work has been carried out on structural dynamic systems under random excitation, there has been a comparatively small amount of this work concentrating on the calculation of the quantities commonly measured in structural dynamic tests. Perhaps the most fundamental of these quantities is the Frequency Response Function (FRF). A number of years ago, Yar and Hammond took an interesting approach to estimating the FRF of a Duffing oscillator system which was based on an approximate solution of the Fokker-Planck-Kolmogorow equation. Despite reproducing the general features of the statistical linearization estimate, the approximation failed to show the presence of the poles at odd multiples of the primary resonance which are known to occur experimentally. The current paper simply extends the work of Yar and Hammond to a higher order of approximation and is thus able to show the existence of a third 'harmonic' in the FRF.

The physics behind the differences between weight and mass, and the concepts of 'free fall', are demonstrated along with explanations and experiments of Sir Issac Newton's three laws of motion.

  1. GNOCIS - an on-line NO{sub X} emission and plant performance optimizer for fossil fuel-fired power plants

    Energy Technology Data Exchange (ETDEWEB)

    Sorge, J.N.; Stallings, J.W.; Smouse, S.M. [Southern Company Services, Inc., Birmingham, AL (United States)


    The Generic NO{sub x} Control Intelligent System (GNOCIS) is an on-line enhancement to existing digital control systems (DCS) designed to reduce NO{sub x} emissions from fossil fuel-fired boilers while meeting other operational constraints on the unit (principally heat rate and other regulated emissions). Using artificial intelligence techniques, GNOCIS utilizes a model of the combustion characteristics of the boiler that includes NO{sub x} emissions and boiler efficiency. The software applies an optimizing procedure to identify the best set points for the plant, which can be implemented automatically without operator intervention in a closed-loop mode, or at the plant`s discretion, conveyed to the plant operators for implementation in an open-loop mode. GNOCIS can be viewed as a low-cost long-term means to maintain short-term optimized plant performance. Development of GNOCIS was funded by a consortium consisting of the Electric Power Research Institute, PowerGen, Radian International, Southern Company, U.K. Department of Trade and Industry, and U.S. Department of Energy. The first commercial installation of GNOCIS was at Georgia Power`s Hammond Unit 4, a 500 MW opposed wallfired boiler. Hammond Unit 4 serves as the host site of a U.S. Department of Energy Clean Coal Technology (CCT) Program project, wherein a stepwise long-term evaluation of three technologies to reduce NO{sub x} emissions was conducted: (1) Advanced Overfire Air (AOFA), (2) Low NO{sub x} Burners (LNB), and (3) LNB + AOFA. A general overview of the CCT project and GNOCIS technology is presented along with performance results from Plant Hammond. Preliminary GNOCIS data from Hammond Unit 4 show an efficiency gain of 0.5 percent, a reduction in fly ash loss-on-ignition of 1-3 percentage points, and NO{sub x} reduction of 10-15 percent at full load. 7 refs., 10 figs., 5 tabs.

    Full Text Available OBJETIVOS: Realizamos uma análise do conceito de causalidade aplicado em psiquiatria e propomos sua abordagem baseada nas ideias de influências causais fracas e de redes causais complexas. MÉTODO: Análise conceitual de artigos e livros selecionados. RESULTADOS: Identificamos o modelo de causalidade INUS, proposto pelo filósofo J. L. Mackie que contorna algumas das dificuldades relacionadas à presença de múltiplas causas interdependentes, como parece ocorrer no caso dos transtornos mentais e mostramos que tal modelo se aplica bem ao TEPT. CONCLUSÃO: Sugerimos que o fracasso na busca de causas "fortes" para os transtornos mentais talvez indique a necessidade de revisão de nossas expectativas, com a adoção de modelos alternativos de causalidade.

  4. [Effectiveness of topical autologous serum treatment in neurotrophic keratopathy]. (United States)

    Guadilla, A M; Balado, P; Baeza, A; Merino, M


    To evaluate the effectiveness of 20% autologous serum as a treatment for neurotrophic keratopathy. A longitudinal, observational and descriptive study was performed on 19 patients (22 eyes) with neurotrophic keratopathy in different stages of Mackie's classification. The following variables were evaluated on the first visit, and then 4 months later: best corrected visual acuity (BCVA), subjective patient symptomatology (faces scale), Schirmer's test without anesthesia (mm), tear film break-up time (BUT) (sg) and healing of the epithelial defect (weeks). The Wilcoxon signed-rank test was used for the statistical analysis of the data. A symptomatic improvement was observed in 100% of the cases, and a 71% improvement in best corrected visual acuity (Pplasma rich in growth factors, may be more effective than the application of 20% autologous serum, due to their greater effect on cell proliferation.

  5. Brogaard's Moral Contextualism

    DEFF Research Database (Denmark)

    Binderup, Lars Grassme


    Brogaard's non-indexical version of moral contextualism has two related problems. It is unable to account for the function of truth-governed assertoric moral discourse, since it leaves two (semantically clearheaded) disputants without any incentive to resolve seemingly contradictory moral claims....... The moral contextualist could explain why people do feel such an incentive by ascribing false beliefs about the semantic workings of their own language. But, secondly, this leaves Brogaard's moral contextualism looking weaker than a Mackie-style invariantist error theory about morals. The latter is equally...... non-objectivist, but less revisionist, since it takes the semantics of moral discourse at face value, and can also explain all of Brogaard's other linguistic evidence....

  6. Challenge and threat motivation: Effects on superficial and elaborative information processing

    Directory of Open Access Journals (Sweden)

    Ricardo eFonseca


    Full Text Available This paper integrates the motivational states of challenge and threat within a dual processing perspective. Previous research has demonstrated that individuals experience a challenge state when individuals have sufficient resources to cope with the demands of a task (Blascovich et al., 1993. Because the experience of resource availability has been shown to be associated with superficial processing (Garcia-Marques & Mackie, 2007, we tested the hypothesis that challenge is associated with superficial processing in two persuasion experiments. Experiment 1 revealed that inducing attitudes of participants in a challenge state was not sensitive to the quality of arguments presented. Experiment 2 demonstrated that the effect occurs even when task engagement, manipulated by the presence (vs. the absence of a task observer (Blascovich et al., 1993, is high. The implications of these results for the BPS model and the cognitive and motivational literature are discussed.

    Full Text Available ‘The Space Between: Languages, Translations and Cultures’ is a special issue of PORTAL Journal of Multidisciplinary International Studies guest-edited by Vera Mackie (University of Melbourne, Ikuko Nakane (University of Melbourne, and Emi Otsuji (University of Technology, Sydney. As Vera Mackie and Stephanie Hemelryk Donald (University of Sydney say in the introduction to the special issue: All of the contributors to this special issue have reflected on the stakes involved in negotiating differences in language and culture. In their research and professional practice they inhabit the ‘space between’: the space between languages, the space between cultures, and the space between academic disciplines. While many of our contributors are located in the Australian university system, we also have contributors from outside that system, as well as contributors who are theorising disparate sites for the negotiation of difference. The most exciting aspect of the papers presented here is the ability to move between the spheres of cultural theory and the everyday. Analytical techniques originally developed for literary and cultural analysis are brought to bear on the texts and practices of everyday life. In addition to the critical essays, three cultural works also intervene in the discussion over what it means to inhabit the ‘space between’ languages, cultures and countries. The guest editors and the PORTAL editorial committee would like to acknowledge and thank the following institutions and individual for the support that made this special issue possible: the Australian Research Council’s Cultural Research Network; the former Institute for International Studies at the University of Technology, Sydney; the School of Historical Studies at the University of Melbourne; and the ARC Cultural Literacies Node Convener, Mark Gibson.

  9. Mutazilite Ghazi Abduljabbar and Contemporary Christian Philosophers of Religion on the Possibility of Miracle

    Directory of Open Access Journals (Sweden)

    Abbas Dehghaninezhad


    Full Text Available Most of western thinkers have declared miracle a self-contradicting and inconsistent notion. Christian theologians have made some efforts to reject this claim and demonstrate the consistency of miracle but it seems they have not succeeded to accomplish much in this regard and failed to substantiate the conceptual coherence of miracle.       We seek to show that the definition Ghazi Abduljabbar offers of miracle tackles this difficulty. In our view this issue indicates the upper hand of Moslem theologians in defining miracles as compared to their Christian counterparts. Problem Stated Swinburne articulates the difficulty as follows: "The first is that evidence that a particular event E occurred and that it is a violation of a supposed law of nature L really only tends to show, not that a law of nature has been violated, but that we have misstated the law of nature. the real law of nature is not really L but some other law L  which allows the occurrence of E… This view amounts to the view that it is logically impossible that there be a violation of a law of nature" (Swinburne, The concept of miracle, p. 19.       To tackle this objection, contemporary western thinkers have sought to demonstrate the consistency of miracle as a concept. Among others, the ideas of L. J. Mackie and Richard Swinburne in this regard are more renowned and hereby we turn to them. Makie's Solution Mackie defines a miracle to be a super natural intervention into the natural world: '... we can give a coherent definition of a miracle. As a supernatural intrusion into the normally closed system that works in accordance with those law. Mackie then defines a miracle to be a super natural intervention into the natural world: '... we can give a coherent definition of a miracle as a supernatural intrusion into the normally closed system that works in Accordance with those laws… (Mackie, p: 21 tem that works in This does not mean the law is false; it only means the

    Full Text Available This paper presents a method of optimum parameter tuning of a PID controller to be used in driving an inertial load by a dc motor thorough a gearbox. Specifically, the method uses genetic algorithms to determine the optimum controller parameters by minimizing the sum of the integral of the squared error and the squared controller output deviated from its steady state value. The paper suggests the use of Ziegler-Nichols settings to form the intervals for the controller parameters in which the population to be formed. The results obtained from the genetic algorithms are compared with the ones from Ziegler-Nichols in both figures and tabular form. Comparatively better results are obtained in the genetic algorithm case.

  12. Evaluation of PID Tuning Methods on Direct Gas-Fired Oven

    Directory of Open Access Journals (Sweden)

    Aborisade, D. O


    Full Text Available This paper studies the temperature control of gas-fired oven using PID controller. Oven control system has the characteristics of non-linearity, time delays and setpoint response. It is difficult to overcome the effects of these factors and get the satisfactory results without appropriately tuning of the PID controller gains required for stability and good transient performance. The Ziegler-Nichols closed loop, Good Gain and Skogestad’s are the PID tuning methods implemented in this paper to control the output temperature of the gas-fired oven system. The PID tuning methods are compared, based on their rise time, maximum overshoot and settling time. The performance of Skogestad’s tuning method at different temperature set point is superior to Ziegler-Nichols closed loop and Good Gain PID tuning method.

    Mnif, Faïçal


    In this note, new tuning methods for Proportional-Integral (PI) are proposed for monotonic time delay systems. Like the Ziegler-Nichols method, the proposed technique requires only parameters obtained from the plant step response. Unlike conventional techniques, the resultant tuning parameters offer the advantage of obtaining stable response with prescribed dynamic behavior with relation to the maximum overshoot. The idea of the design is simple and relies on basics learned in an introductory control course.

    We determine the reaction progress function for an ideal hot spot model problem. The considered problem has an exact analytic solution that can derived from a reduction of Nichols statistical hot spot model. We perform numerical calculations to verify the analytic solution and to illustrate the error realized in real, finite systems. We show how the baseline problem, which does not distinguish between the reactant and product densities, can be scaled to handle general cases for which the two densities differ.

  6. Automatic Tuning Of Proportional-Integral-Derivative (Pid Controller Using Particle Swarm Optimization (Pso Algorithm

    Directory of Open Access Journals (Sweden)

    S. J. Bassi


    Full Text Available The proportional-integral-derivative (PID controllers are the most popular controllers used in industry because of their remarkable effectiveness, simplicity of implementation and broad applicability. However, manual tuning of these controllers is time consuming, tedious and generally lead to poor performance. This tuning which is application specific also deteriorates with time as a result of plant parameter changes. This paper presents an artificial intelligence (AI method of particle swarm optimization (PSO algorithm for tuning the optimal proportional-integral derivative (PID controller parameters for industrial processes. This approach has superior features, including easy implementation, stable convergence characteristic and good computational efficiency over the conventional methods. Ziegler- Nichols, tuning method was applied in the PID tuning and results were compared with the PSO-Based PID for optimum control. Simulation results are presented to show that the PSO-Based optimized PID controller is capable of providing an improved closed-loop performance over the Ziegler- Nichols tuned PID controller Parameters. Compared to the heuristic PID tuning method of Ziegler-Nichols, the proposed method was more efficient in improving the step response characteristics such as, reducing the steady-states error; rise time, settling time and maximum overshoot in speed control of DC motor.

  7. Longitudinal control of aircraft dynamics based on optimization of PID parameters (United States)

    Deepa, S. N.; Sudha, G.


    Recent years many flight control systems and industries are employing PID controllers to improve the dynamic behavior of the characteristics. In this paper, PID controller is developed to improve the stability and performance of general aviation aircraft system. Designing the optimum PID controller parameters for a pitch control aircraft is important in expanding the flight safety envelope. Mathematical model is developed to describe the longitudinal pitch control of an aircraft. The PID controller is designed based on the dynamic modeling of an aircraft system. Different tuning methods namely Zeigler-Nichols method (ZN), Modified Zeigler-Nichols method, Tyreus-Luyben tuning, Astrom-Hagglund tuning methods are employed. The time domain specifications of different tuning methods are compared to obtain the optimum parameters value. The results prove that PID controller tuned by Zeigler-Nichols for aircraft pitch control dynamics is better in stability and performance in all conditions. Future research work of obtaining optimum PID controller parameters using artificial intelligence techniques should be carried out.

    Lima, F. W. S.


    Through Monte Carlo simulations, we study the evolution of the four strategies: Ethnocentric, altruistic, egoistic and cosmopolitan in one community of individuals. Interactions and reproduction among computational agents are simulated on undirected and semi-directed Barabási-Albert (BA) networks. We study the Hammond-Axelrod (HA) model on undirected and semi-directed BA networks for the asexual reproduction case. With a small modification in the traditional HA model, our simulations showed that egoism wins, differently from other results found in the literature where ethnocentric strategy is common. Here, mechanisms such as reciprocity are absent.

  4. Quantitation of microorganic compounds in waters of the Great Lakes by adsorption on activated carbon (United States)

    Daniels, Stacy L.; Kempe, Lloyd L.; Graham, E. S.; Beeton, Alfred M.


    Microorganic compounds in waters of Lakes Michigan and Huron have been sampled by adsorption on activated carbon in filters installed aboard the M/V Cisco and at the Hammond Bay Laboratory of the U.S. Bureau of Commercial Fisheries. The organic compounds were eluted from the carbon according to techniques developed at the U.S. Public Health Service. On the assumption that chloroform eluates represent less polar compounds from industrial sources and alcohol eluates the more polar varieties of natural origin, plots of chloroform eluates against alcohol eluates appear to be useful in judging water qualities. Based upon these criteria, the data in this paper indicate that both the waters of northern Lake Michigan and of Lake Huron, in the vicinity of Hammond Bay, Michigan, are relatively free from pollution. The limnetic waters of Lake Michigan showed a particularly high ratio of alcohol to chloroform eluates. Data for monthly samples indicated that this ratio fluctuated seasonally. The periodicity of the fluctuations was similar to those of lake levels and water temperatures.

  5. Auto-monitoring: theoretical touchstone or circular catch-all?

    Directory of Open Access Journals (Sweden)

    Nick Hammond


    Full Text Available Until I read Ray McAleese's paper, I perhaps had a rather simplistic psychologist's view of concept mapping. It was, I felt, a technique - one of several - that helped learners to articulate their burgeoning understanding of some topic, providing a canvas on which to record, expand and manipulate their knowledge. The activities involved in concept mapping could be linked to well-known psychological principles of understanding, memorization and learning: effort, elaboration and depth of processing; generation and enactment effects; encoding specificity and encoding variability; the distinctions between explicit and implicit representations; metacognitive strategies and reflection, and so forth (Hammond 1993. These psychological underpinnings, while not in any sense providing an integrated 'theory' of concept mapping, give a view of when and why the use of concept mapping might be effective in some situations and not in others, and how different concept mapping tools differ in the claims they are making about their educational use (Trapp, Reader and Hammond 1992.

  8. Forming implicit and explicit attitudes toward individuals: social group association cues. (United States)

    McConnell, Allen R; Rydell, Robert J; Strain, Laura M; Mackie, Diane M


    The authors explored how social group cues (e.g., obesity, physical attractiveness) strongly associated with valence affect the formation of attitudes toward individuals. Although explicit attitude formation has been examined in much past research (e.g., S. T. Fiske & S. L. Neuberg, 1990), in the current work, the authors considered how implicit as well as explicit attitudes toward individuals are influenced by these cues. On the basis of a systems of evaluation perspective (e.g., R. J. Rydell & A. R. McConnell, 2006; R. J. Rydell, A. R. McConnell, D. M. Mackie, & L. M. Strain, 2006), the authors anticipated and found that social group cues had a strong impact on implicit attitude formation in all cases and on explicit attitude formation when behavioral information about the target was ambiguous. These findings obtained for cues related to obesity (Experiments 1 and 4) and physical attractiveness (Experiment 2). In Experiment 3, parallel findings were observed for race, and participants holding greater implicit racial prejudice against African Americans formed more negative implicit attitudes toward a novel African American target person than did participants with less implicit racial prejudice. Implications for research on attitudes, impression formation, and stigma are discussed. (c) 2008 APA, all rights reserved

  9. Evaluation of dispersion-corrected density functional theory (B3LYP-DCP) for compounds of biochemical interest. (United States)

    Lill, Sten O Nilsson


    An evaluation of a dispersion-corrected density functional theory method (B3LYP-DCP) [I.D. Mackie, G.A. DiLabio, Interactions in large, polyaromatic hydrocarbon dimers: application of density functional theory with dispersion corrections, J. Phys. Chem. A 112 (2008) 10968-10976] for three systems of biochemical interest is presented. Firstly, structures and energies of isomers of the tripeptide Phe-Gly-Phe have been compared with CCSD(T)/CBS//RI-MP2/cc-pVTZ literature values. In the system aromatic interactions compete with XH-pi (X=C, N) interactions and hydrogen bonds which makes it a reliable model for proteins. The resulting mean absolute deviation between B3LYP-DCP and CCSD(T)/CBS relative energies is found to be 0.50 kcal mol(-1). Secondly, a phenylalanine derivative featuring a CH-pi interaction has been investigated. A comparison between the optimized geometry and X-ray crystal data shows that B3LYP-DCP accurately predicts the interaction between the two aromatic rings. Thirdly, the dipeptide Ac-Phe-Phe-NH(2) which contains an edge-to-face interaction between two aromatic rings has been studied. The study demonstrates the general applicability of the B3LYP-DCP method on systems which features interactions typically present in biochemical compounds.

  10. In Possession of a Stolen Weapon: From John Gay’s Macheath to Rubén Blades’ Pedro Navaja

    Directory of Open Access Journals (Sweden)

    Antonio Viselli


    Full Text Available This article analyses the cult salsa song “Pedro Navaja” by Panamanian artist Rubén Blades and the relevance of narrating such a genre peculiar to dancing, an re-writing of “Mack the Knife” – or Die Moritat von Mackie Messer – one which contains, as a sort of mise-en-abyme, elements not only of Kurt Weill’s song, but of both John Gay’s The Beggar’s Opera and Bertolt Brecht’s The Threepenny Opera. This study focuses on the fertile adaptation history of the highwayman Macheath since Gay’s work, on close-readings of “Pedro Navaja” – a narrativized cerebral salsa song – and on the ethics of adapting a character, story or genre. Finally, when the character Pedro Navaja is adapted from Blades’ song by a cineaste and playwright, Blades, furious with what others have done with ‘his’ character, decides to resuscitate his eponymous hero killed off at the end of the original song in order to regain the authority of his creation. From theoretical questions including how to read an adaptation or what constitutes an adaptation, this article focuses on the diachronic recurrences of a specific character-type, on the significance of juxtaposing particular historical junctures and on the violence of adaptation and authorship.

  11. On the classification of diseases. (United States)

    Smart, Benjamin


    Identifying the necessary and sufficient conditions for individuating and classifying diseases is a matter of great importance in the fields of law, ethics, epidemiology, and of course, medicine. In this paper, I first propose a means of achieving this goal, ensuring that no two distinct disease-types could correctly be ascribed to the same disease-token. I then posit a metaphysical ontology of diseases-that is, I give an account of what a disease is. This is essential to providing the most effective means of interfering with disease processes. Following existing work in the philosophy of medicine and epidemiology (primarily Christopher Boorse; Caroline Whitbeck; Alexander Broadbent), philosophy of biology (Joseph LaPorte; D.L. Hull), conditional analyses of causation (J.L. Mackie; David Lewis), and recent literature on dispositional essentialism (Stephen Mumford and Rani Anjum; Alexander Bird), I endorse a dispositional conception of disease. Following discussion of various conceptions of disease-identity, their relations to the clinical and pathological effects of the diseases in question, and how diseases are treated, I conclude (i) that diseases should be individuated by their causes, and (ii) that diseases are causal processes best seen as simultaneously acting sequences of mutually manifesting dispositions.

Furthermore, they can contribute for a “metamorphosis-memory”, a kind of memory that reconstructs itself continuously according to new representations of dictatorships in films. The frame of reference includes theories by Bakhtin, Baudrillard, Benjamin, Debord, Derrida, Halbwachs,Metz, Nichols and Sarlo, among others.

  1. The changing role of the medical illustrator. (United States)

    Morton, R; Nicholls, J; Williams, R


    The annual meeting of the Australian Institute of Medical and Biological Illustration in Melbourne in November 1998 included keynote addresses from Richard Morton and Robin Williams. Both speakers looked at the future of the medical illustration profession, and in particular the impact of new technology. This matter was also addressed by Joe Nicholls in a presentation given at the Institute of Medical Illustrators' Annual Symposium in Warwick, UK, in September 1998. This paper is a synthesis of the ideas presented by these three speakers and elaborates on common themes in their presentations.

    The large amount of data collected from three different centrifugal liquid helium pumps tested, namely with 80, 600 and 1200 g/s nominal mass flow are reviewed. The data include the analysis of the characteristic curves, their total efficiencies, their Net Positive Suction Head (NPSH) and the slip factor. The 1200 g/s pumps tested are of the full emission type, with curved blades, whilst the other pumps have straight blades. The pumps were also tested at different rotary speeds. The pumps were manufactured by Barber \\& Nichols (Denver, USA). (C) 2009 Elsevier Ltd. All rights reserved.

  11. Wilde Nostalgia: Queer Tradition in Beverley Nichols’s Garden Trilogies

    Directory of Open Access Journals (Sweden)

    Joshua Adair


    Full Text Available This essay examines the long-standing and far-reaching influence of Oscar Wilde’s public persona – both historical and mythical – on author Beverley Nichols. Nichols, famous during his lifetime for both his non-fiction and reportage, has sustained his fame primarily through his Allways and Merry Hall gardening trilogies. These feature a semi-autobiographical version of the author who is self-styled as a spiritual successor who pays homage to, and extends the legacy of, Oscar Wilde and his endless bon mots, serving up irony, humor, and social commentary in an engaging, urbane manner while further shaping the Wildean identity that prevailed as an iconic gay style throughout much of the last century and that endures, in some forms, even today. Keywords: queer theory, Oscar Wilde, Beverley Nichols, Pet Shop Boys, queer identityOscar Wilde’s final words as his three harrowing trials and, indeed, his remarkably verbal life drew near their close – “And I? May I say nothing, my Lord?” – serve as a potent reminder of the many forces that conspired to silence the man, his work, and the desire he came to represent, for better or worse, to so many. Nearly a century after that utterance, his words continue to resonate, as a refrain, perhaps even a plaintive cry, for the Pet Shop Boys (PSB hereafter and many others, suggesting that Wilde, as the long-reigning patron saint of queer men, still holds sway in matters of self-styling and queer identity formation based in nostalgia. From the spectacle of his downfall emerged a mythical Wilde – martyr, champion of queer desire, arbiter of style and wit – based in the biographical as much as the fanciful, who inspires Wilde nostalgia even today. Beverley Nichols, especially in his two mid-century “gardening” trilogies, pays homage to the cultural construct we call Oscar Wilde with his endless bon mots, serving up irony, humor, and social commentary in an engaging, urbane manner while further

    Full Text Available This paper proposes the application of neural network as a controller to isolate engine vibration in an active engine mounting system. It has been shown that the NARMA-L2 neurocontroller has the ability to reject disturbances from a plant. The disturbance is assumed to be both impulse and sinusoidal disturbances that are induced by the engine. The performance of the neural network controller is compared with conventional PD and PID controllers tuned using Ziegler-Nichols. From the result simulated the neural network controller has shown better ability to isolate the engine vibration than the conventional controllers.

  8. Field Comparisons of the Gravid Aedes Trap (GAT) and BG-Sentinel Trap for Monitoring Aedes albopictus (Diptera: Culicidae) Populations and Notes on Indoor GAT Collections in Vietnam. (United States)

    Johnson, Brian J; Hurst, Tim; Quoc, Hung Luu; Unlu, Isik; Freebairn, Christopher; Faraji, Ary; Ritchie, Scott A


    We report on the use of the Gravid Aedes Trap (GAT) as a surveillance device for Aedes albopictus (Skuse) relative to the BG-Sentinel (BGS) trap in field studies conducted in Trenton, NJ, and on Hammond Island, Queensland, Australia. A parallel study conducted in Nha Trang, Vietnam, assessed the use of the GAT as an indoor surveillance device as well as the use of canola oil as a noninsecticide killing agent. In Trenton and Hammond Island, the GAT collected fewer male (0.40 ± 0.12 and 0.43 ± 0.30, respectively) and female (3.05 ± 0.67 and 2.7 ± 2.3, respectively) Ae. albopictus than the BGS trap (males: 3.54 ± 1.26 and 3.75 ± 0.83; females: 4.66 ± 1.18 and 3.9 ± 0.23) over their respective sampling periods (i.e., 24 h for the BGS and 1 wk for the GAT). Despite differences in capture rates, the percentage of traps positive for female Ae. albopictus was similar between the BGS and GAT (Trenton: 60.1 ± 6.3% and 64.4 ± 4.1%; Hammond: 87.5 ± 6.9% and 80.0 ± 8.2%). In Nha Trang, the GAT was equally effective indoors and outdoors with (10 g hay or 3 g fish food) and without (water or empty) infusion. Additionally, no significant decrease in collections was observed between GATs set with canola oil or long-lasting insecticidal net. In summary, both traps were successful in monitoring female Ae. albopictus over their respective trapping intervals, but would be best used to complement each other to monitor both sexes and all physiological stages of female Ae. albopictus However, the versatility and low-cost of the GAT makes it an attractive alternative to the more expensive BGS trap.

  9. Assessment of Multiple Risk Outcomes, Strengths, and Change with the START:AV: A Short-Term Prospective Study with Adolescent Offenders (United States)

    Viljoen, Jodi L.; Beneteau, Jennifer L.; Gulbransen, Erik; Brodersen, Etta; Desmarais, Sarah L.; Nicholls, Tonia L.; Cruise, Keith R.


    The Short-Term Assessment of Risk and Treatability: Adolescent Version (START:AV; Nicholls, Viljoen, Cruise, Desmarais, & Webster, 2010; Viljoen, Cruise, Nicholls, Desmarais, & Webster, in preparation) is a clinical guide designed to assist in the assessment and management of adolescents’ risk for adverse events (e.g., violence, general offending, suicide, victimization). In this initial validation study, START:AV assessments were conducted on 90 adolescent offenders (62 male, 28 female), who were prospectively followed for a 3-month period. START:AV assessments had good to excellent inter-rater reliability and strong concurrent validity with Structured Assessment of Violence Risk in Youth assessments (SAVRY; Borum, Bartel, & Forth, 2006). START:AV risk estimates and Vulnerability total scores predicted multiple adverse outcomes, including violence towards others, offending, victimization, suicidal ideation, and substance abuse. In addition, Strength total scores inversely predicted violence, offending, and street drug use. During the 3-month follow-up, risk estimates changed in at least one domain for 92% of youth, and 27% of youth showed reliable changes in Strength and/or Vulnerability total scores (reliable change index, 90% confidence interval; Jacobsen & Truax, 1991). While these findings are promising, a strong need exists for further research on the START:AV, the measurement of change, and on the role of strengths in risk assessment and treatment-planning.

    A highly convergent synthesis was developed for the novel dopamine agonist dinapsoline (12) (Ghosh, D.; Snyder, S. E.; Watts, V. J.; Mailman, R. B.; Nichols, D. E. 8,9-Dihydroxy-2,3,7, 11b-tetrahydro-1H-naph[1,2,3-de]isoquinoline: A Potent Full Dopamine D(1) Agonist Containing a Rigid beta-Phenyldopamine Pharmacophore. J. Med. Chem. 1996, 39 (2), 549-555). The crucial step in the new synthesis was a free radical-initiated cyclization to give the complete dinapsoline framework. The improved synthesis required half as many steps as the original procedure (Nichols, D. E.; Mailman, R.; Ghosh, D. Preparation of novel naphtho[1,2,3-de]isoquinolines as dopamine receptor ligands. PCT Int. Appl. WO 9706799 A1, Feb 27, 1997). One of the late-stage intermediates (11) was resolved into a pair of enantiomers. From there, the (R)-(+)-12 (absolute configuration by X-ray) of dinapsoline was identified as the active enantiomer. In unilateral 6-hydroxydopamine (6-OHDA)-lesioned rats, (+)-dinapsoline showed robust rotational behavior comparable to that of an external benchmark, trans-4,5,5a,6,7,11b-hexahydro-2-propyl-benzo[f]thieno[2,3-c]quinoline-9,10-diol, hydrochloride 18 (Michaelides, M.

    Levy Michael H


    Full Text Available Abstract Background Health-state utilities for prisoners have not been described. Methods We used data from a 1996 cross-sectional survey of Australian prisoners (n = 734. Respondent-level SF-36 data was transformed into utility scores by both the SF-6D and Nichol's method. Socio-demographic and clinical predictors of SF-6D utility were assessed in univariate analyses and a multivariate general linear model. Results The overall mean SF-6D utility was 0.725 (SD 0.119. When subdivided by various medical conditions, prisoner SF-6D utilities ranged from 0.620 for angina to 0.764 for those with none/mild depressive symptoms. Utilities derived by the Nichol's method were higher than SF-6D scores, often by more than 0.1. In multivariate analysis, significant independent predictors of worse utility included female gender, increasing age, increasing number of comorbidities and more severe depressive symptoms. Conclusion The utilities presented may prove useful for future economic and decision models evaluating prison-based health programs.

  12. Complete genome sequence of Treponema pallidum ssp. pallidum strain SS14 determined with oligonucleotide arrays

    Directory of Open Access Journals (Sweden)

    Sodergren Erica


    Full Text Available Abstract Background Syphilis spirochete Treponema pallidum ssp. pallidum remains the enigmatic pathogen, since no virulence factors have been identified and the pathogenesis of the disease is poorly understood. Increasing rates of new syphilis cases per year have been observed recently. Results The genome of the SS14 strain was sequenced to high accuracy by an oligonucleotide array strategy requiring hybridization to only three arrays (Comparative Genome Sequencing, CGS. Gaps in the resulting sequence were filled with targeted dideoxy-terminators (DDT sequencing and the sequence was confirmed by whole genome fingerprinting (WGF. When compared to the Nichols strain, 327 single nucleotide substitutions (224 transitions, 103 transversions, 14 deletions, and 18 insertions were found. On the proteome level, the highest frequency of amino acid-altering substitution polymorphisms was in novel genes, while the lowest was in housekeeping genes, as expected by their evolutionary conservation. Evidence was also found for hypervariable regions and multiple regions showing intrastrain heterogeneity in the T. pallidum chromosome. Conclusion The observed genetic changes do not have influence on the ability of Treponema pallidum to cause syphilitic infection, since both SS14 and Nichols are virulent in rabbit. However, this is the first assessment of the degree of variation between the two syphilis pathogens and paves the way for phylogenetic studies of this fascinating organism.

  13. Multi-objective PID Optimization for Speed Control of an Isolated Steam Turbine using Gentic Algorithm

    Sanjay Kr. Singh


    Full Text Available This study focuses on multi-objective optimization of the PID controllers for optimal speed control for an isolated steam turbine. In complex operations, optimal tuning plays an imperative role in maintaining the product quality and process safety. This study focuses on the comparison of the optimal PID tuning using Multi-objective Genetic Algorithm (NSGA-II against normal genetic algorithm and Ziegler Nichols methods for the speed control of an isolated steam turbine. Isolated steam turbine not being connected to the grid; hence is usually used in refineries as steam turbine, where a hydraulic governor is used for the speed control. The PID controller for the system has been designed and implemented using MATLAB and SIMULINK and the results of the design methods have been compared, analysed and conclusions indicates that the significant improvement of results have been obtained by the Multi-Objective GA based optimization of PID as much faster response is obtained as compared to the ordinary GA and Ziegler Nichols method.

  14. Intelligent algorithm tuning PID method of function electrical stimulation using knee joint angle. (United States)

    Qiu, Shuang; He, Feng; Tang, Jiabei; Xu, Jiapeng; Zhang, Lixin; Zhao, Xin; Qi, Hongzhi; Zhou, Peng; Cheng, Xiaoman; Wan, Baikun; Ming, Dong


    Functional electrical stimulation (FES) could restore motor functions for individuals with spinal cord injury (SCI). By applying electric current pulses, FES system could produce muscle contractions, generate joint torques, and thus, achieve joint movements automatically. Since the muscle system is highly nonlinear and time-varying, feedback control is quite necessary for precision control of the preset action. In the present study, we applied two methods (Proportional Integral Derivative (PID) controller based on Back Propagation (BP) neural network and that based on Genetic Algorithm (GA)), to control the knee joint angle for the FES system, while the traditional Ziegler-Nichols method was used in the control group for comparison. They were tested using a muscle model of the quadriceps. The results showed that intelligent algorithm tuning PID controller displayed superior performance than classic Ziegler-Nichols method with constant parameters. More particularly, PID controller tuned by BP neural network was superior on controlling precision to make the feedback signal track the desired trajectory whose error was less than 1.2°±0.16°, while GA-PID controller, seeking the optimal parameters from multipoint simultaneity, resulted in shortened delay in the response. Both strategies showed promise in application of intelligent algorithm tuning PID methods in FES system.

  15. QFT Based Robust Positioning Control of the PMSM Using Automatic Loop Shaping with Teaching Learning Optimization

    Directory of Open Access Journals (Sweden)

    Nitish Katal


    Full Text Available Automation of the robust control system synthesis for uncertain systems is of great practical interest. In this paper, the loop shaping step for synthesizing quantitative feedback theory (QFT based controller for a two-phase permanent magnet stepper motor (PMSM has been automated using teaching learning-based optimization (TLBO algorithm. The QFT controller design problem has been posed as an optimization problem and TLBO algorithm has been used to minimize the proposed cost function. This facilitates designing low-order fixed-structure controller, eliminates the need of manual loop shaping step on the Nichols charts, and prevents the overdesign of the controller. A performance comparison of the designed controller has been made with the classical PID tuning method of Ziegler-Nichols and QFT controller tuned using other optimization algorithms. The simulation results show that the designed QFT controller using TLBO offers robust stability, disturbance rejection, and proper reference tracking over a range of PMSM’s parametric uncertainties as compared to the classical design techniques.

    Kumar Jaiswal, Arun; Tiwari, Sandeep; Jamal, Syed Babar; Barh, Debmalya; Azevedo, Vasco; Soares, Siomar C.


    Sexually transmitted infections (STIs) are caused by a wide variety of bacteria, viruses, and parasites that are transmitted from one person to another primarily by vaginal, anal, or oral sexual contact. Syphilis is a serious disease caused by a sexually transmitted infection. Syphilis is caused by the bacterium Treponema pallidum subspecies pallidum. Treponema pallidum (T. pallidum) is a motile, gram-negative spirochete, which can be transmitted both sexually and from mother to child, and can invade virtually any organ or structure in the human body. The current worldwide prevalence of syphilis emphasizes the need for continued preventive measures and strategies. Unfortunately, effective measures are limited. In this study, we focus on the identification of vaccine targets and putative drugs against syphilis disease using reverse vaccinology and subtractive genomics. We compared 13 strains of T. pallidum using T. pallidum Nichols as the reference genome. Using an in silicoapproach, four pathogenic islands were detected in the genome of T. pallidum Nichols. We identified 15 putative antigenic proteins and sixdrug targets through reverse vaccinology and subtractive genomics, respectively, which can be used as candidate therapeutic targets in the future.

  17. Una critítica al criterio de correción para distinguir entre tipos de procesos subyacentes en una teoria híbrida de mindreading

    Directory of Open Access Journals (Sweden)

    Fernanda Velázquez Coccia

    Full Text Available Resumen: Los enfoques híbridos de mindreading postulan procesos de "teoría" y "simulación" como subyacentes a esta capacidad. Un problema actual es ofrecer criterios para evaluar las teorías híbridas. Aquí, analizaré el "criterio de corrección" propuesto por Stich & Nichols (2003, Nichols & Stich 2003 para discriminar entre tipos de procesos subyacentes a mindreading. Según éste, si el resultado demindreading es correcto es probable que el proceso subyacente sea de tipo simulacional, y si el resultado de mindreading es incorrecto es probable que el proceso subyacente sea de bases de información (o teoría. Sostendré que la corrección o incorrección del resultado de mindreading no permite distinguir entre tipos de proceso. Intentaré mostrar que los argumentos a favor de un proceso simulacional subyacente a mindreading exitoso no descartan explicaciones de bases de información para este mismo fenómeno. A su vez, argumentaré que es posible que un proceso de tipo simulacional subyazca a mindreading incorrecto.

  18. Tunning PID controller using particle swarm optimization algorithm on automatic voltage regulator system (United States)

    Aranza, M. F.; Kustija, J.; Trisno, B.; Hakim, D. L.


    PID Controller (Proportional Integral Derivative) was invented since 1910, but till today still is used in industries, even though there are many kind of modern controllers like fuzz controller and neural network controller are being developed. Performance of PID controller is depend on on Proportional Gain (Kp), Integral Gain (Ki) and Derivative Gain (Kd). These gains can be got by using method Ziegler-Nichols (ZN), gain-phase margin, Root Locus, Minimum Variance dan Gain Scheduling however these methods are not optimal to control systems that nonlinear and have high-orde, in addition, some methods relative hard. To solve those obstacles, particle swarm optimization (PSO) algorithm is proposed to get optimal Kp, Ki and Kd. PSO is proposed because PSO has convergent result and not require many iterations. On this research, PID controller is applied on AVR (Automatic Voltage Regulator). Based on result of analyzing transient, stability Root Locus and frequency response, performance of PID controller is better than Ziegler-Nichols.

    Full Text Available Witnessing the euphoria of the era of biotechnology in the late twentieth century, Crichton exposes the theme of biotechnology in his works. In Jurassic Park, he voices his concern about the impact of the use of biotechnology to preserve nature and its living creatures. He further describes how the purpose of preserving nature and the creatures has turned out to be destructive. This article discusses Crichton's main character, Hammond, who attempts to control nature by genetically recreating the extinct fossil animals. It seems that the attempt ignores his human limitations. Although he is confident that has been equipped with the technology, he forgets to get along with nature. His way of using technology to accomplish his purpose proves not to be in harmony with nature. As a consequence, nature fights back. And he is conquered.

  20. Millisecond precision psychological research in a world of commodity computers: new hardware, new problems? (United States)

    Plant, Richard R; Turner, Garry


    Since the publication of Plant, Hammond, and Turner (2004), which highlighted a pressing need for researchers to pay more attention to sources of error in computer-based experiments, the landscape has undoubtedly changed, but not necessarily for the better. Readily available hardware has improved in terms of raw speed; multi core processors abound; graphics cards now have hundreds of megabytes of RAM; main memory is measured in gigabytes; drive space is measured in terabytes; ever larger thin film transistor displays capable of single-digit response times, together with newer Digital Light Processing multimedia projectors, enable much greater graphic complexity; and new 64-bit operating systems, such as Microsoft Vista, are now commonplace. However, have millisecond-accurate presentation and response timing improved, and will they ever be available in commodity computers and peripherals? In the present article, we used a Black Box ToolKit to measure the variability in timing characteristics of hardware used commonly in psychological research.

  1. Black women queering the mic: Missy Elliott disturbing the boundaries of racialized sexuality and gender. (United States)

    Lane, Nikki


    Though there were and always have been djs, dancers, graffiti artists, and rappers who were Black women, they are placed on the periphery of hip-hop culture; their voices, along with "gay rappers" and "white rappers" devalued and their contribution to the global rise of hip-hop either forgotten or eschewed. This article is an attempt to articulate the existence of Black women who work outside of the paradigms of the "silence, secrecy, and a partially self-chosen invisibility" that Evelynn Hammonds describes. At the center of this article lies an attempt to locate a new configuration and expression of desire and sexuality, opening a door, wide open, to gain a different view of Black women, their sexuality, their expression of it, and the complexities that arise when they attempt to express it in hip hop nation language.

    Chua, Kah Hean; Wee, Loo Kang; Tan, Ching


    Multimedia engages an audience through a combination of text, audio, still images, animation, video, or interactivity-based content formats. Along this vein, free platforms have been seen to allow budding enthusiasts to create multimedia content. For example, Google sites (Wee, 2012b) offer creative opportunities in website development that enable text insertion, still image, video and animation embedding, along with audio and hyper-interactive links to simulations (Christian & Esquembre, 2012; Wee, 2013; Wee, Goh, & Chew, 2013; Wee, Goh, & Lim, 2013; Wee, Lee, Chew, Wong, & Tan, 2015). This chapter focuses on the video aspect of multimedia, which can be positioned as a component to any effective self-paced on-line lesson that would be available anytime, anywhere via computer or mobile devices. The multimedia video approach aims to help users overcome barriers in creating engaging, effective and meaningful content (Barron & Darling-Hammond, 2008) for teaching and learning in an online envi...

  3. Does high-stakes testing increase cultural capital among low-income and racial minority students?

    Directory of Open Access Journals (Sweden)

    Won-Pyo Hong


    Full Text Available This article draws on research from Texas and Chicago to examine whether high-stakes testing enables low-income and racial minority students to acquire cultural capital. While students' performance on state or district tests rose after the implementation of high-stakes testing and accountability policies in Texas and Chicago in the 1990s, several studies indicate that these policies seemed to have had deleterious effects on curriculum, instruction, the percentage of students excluded from the tests, and student dropout rates. As a result, the policies seemed to have had mixed effects on students' opportunities to acquire embodied and institutionalized cultural capital. These findings are consistent with the work of Shepard (2000, Darling-Hammond (2004a, and others who have written of the likely negative repercussions of high-stakes testing and accountability policies.

  4. Robotics for Learning

    Toh, Dennis; Lim, Matthew; Wee, Loo Kang; Ong, Matthew


    Teaching Robotics is about empowering students to create and configure robotics devices and program computers to nurture in students the skill sets necessary to play an active role in society. The robot in Figure 1 focuses on the design of scaffolds and physical assembly methods, coupled with a computer logic program to make that makes it move or behave in a very precise (remote controlled or autonomous) manner. This enables students to investigate, explore and refine the program to affect the robots. The Robotics approach takes into account the increasing popularity of Computer Science and the learning by doing (Schank, Berman, & Macpherson, 1999) approach to solve complex problems and use computers meaningfully in learning (Barron & Darling-Hammond, 2008; Jonassen, Howland, Marra, & Crismond, 2008). In Singapore, teachers and students in Woodlands Ring Secondary and Rulang Primary have incorporated robotics to varying extents into formal and informal curricula. In addition, other less expensive ...

  5. A hydrologically explicit, spatially exact, classification of landforms for Canada at 1:500,000 scale. (United States)

    MacMillan, Robert A.; Geng, Xiaoyuan; Smith, Scott; Zawadzka, Joanna; Hengl, Tom


    A new approach for classifying landform types has been developed and applied to all of Canada using a 250 m DEM. The resulting LandMapR classification has been designed to provide a stable and consistent spatial fabric to act as initial proto-polygons to be used in updating the current 1:1 M scale Soil Landscapes of Canada map to 1:500,000 scale. There is a desire to make the current SLC polygon fabric more consistent across the country, more correctly aligned to observable hydrological and landscape features, more spatially exact, more detailed and more interpretable. The approach is essentially a modification of the Hammond (1954) criteria for classifying macro landform types as implemented for computerized analysis by Dikau (1989, 1991) and Brabyn (1998). The major modification is that the key input variables of local relief and relative position in the landscape are computed for specific hillslopes that occur between individual, explicitly defined, channels and divides. While most approaches, including Dikau et al., (1991) and SOTER (Dobos et al., 2005) compute relative relief and landscape position within a neighborhood analysis window (NAW) of some fixed size (9,600 m and 1 km respectively) the LandMapR method assesses these variables based on explicit analysis of flow paths between locally defined divides and channels (or lakes). We have modified the Hammond criteria by splitting the lowest relief class of 0-30 m into 4 classes of 0-0 m, 0-1 m, 1-10 m and 10-30 m) in order to be able to better differentiate subtle landform features in areas of low relief. Essentially this enables recognition of lakes and open water (0 relief and 0 slope), shorelines and littoral zones (0-1 m), nearly flat, low-relief landforms (1-10 m) and low relief undulating plains (10-30 m). We also modified the Hammond approach for separating upper versus lower landform positions used to differentiate flat areas in uplands from flat lowlands. We instead differentiate 3 relative slope

  6. Evolution of ethnocentrism on undirected and directed Barabási-Albert networks (United States)

    Lima, F. W. S.; Hadzibeganovic, Tarik; Stauffer, Dietrich


    Using Monte Carlo simulations, we study the evolution of contingent cooperation and ethnocentrism in the one-shot game. Interactions and reproduction among computational agents are simulated on undirected and directed Barabási-Albert (BA) networks. We first replicate the Hammond-Axelrod model of in-group favoritism on a square lattice and then generalize this model on undirected and directed BA networks for both asexual and sexual reproduction cases. Our simulations demonstrate that irrespective of the mode of reproduction, the ethnocentric strategy becomes common even though cooperation is individually costly and mechanisms such as reciprocity or conformity are absent. Moreover, our results indicate that the spread of favoritism towards similar others highly depends on the network topology and the associated heterogeneity of the studied population.

  7. Spin-Rotation Coupling in Gravitation with Torsion

    Institute of Scientific and Technical Information of China (English)


    Based on the theory of gravitation with torsion developed by Hammond [Rep. Prog. Phys. 65 (2002)599], the interaction between the intrinsic spin of a particle and the mass source is calculated. It is shown that spin can interact with the gravitimagnetic field created by a rotational mass, where the spin-rotation coupling is also discussed.According to the recent torsion pendulum experiment with polarized electrons by Heckel et al. [Phys. Rev. Lett. 97(2006) 021603], we set a new limit on the value of the torsion coupling constant K as K ∈ [0.53, 0.95], which has improved many orders than the constraints from the early spin-spin experiment with K < 2 × 1014.

    Pratissoli, Dirceu; Polanczyk, Ricardo A; Holtz, Anderson M; Tamanhoni, Tiago; Celestino, Flávio N; Borges Filho, Raul da C


    The aim of this research was to evaluate the biological behaviour of melonworm at different natural and artificial diets. Squash cultivar jacaré, cucumber, summer squash and an artificial diets developed by Hensley & Hammond for the sugarcane borer were tried. The research was carried out in the Laboratório de Entomologia do Centro de Ciências Agrárias of the Universidade Federal do Espírito Santo, in climatized room at 25 +/- 1 masculineC, relative humidity of 70 +/- 10% and 14h photofase. The caterpillars fed on each substrate during the whole life cycle. Differences in duration of the larval period, larvae and pupae survival, adult longevity and number of eggs were registered between the substrates. The results show that the best diet for rearing is the artificial one. Between the natural diets the cucumber showed the best results.

  10. The effect of substrate stretching on the thin-film distribution near an alveolar corner (United States)

    Chini, Greg; Jensen, Oliver


    Because the lung contains an extensive and highly-curved air--liquid interface, surface tension forces play a central role in respiration. Anatomical studies have shown that the lung's liquid-film lining accumulates in the corners of polyhedral alveoli (the terminal airway units). We study the thin-film distribution near an alveolar corner by numerically integrating a model equation. In the absence of substrate stretching, the film attains a quasi-steady form in which a satellite drop drains slowly into a corner puddle. Canonical `Hammond draining' dynamics are observed, with the (perturbation) pressure varying rapidly and monotonically between the puddle and droplet. When the substrate is stretched, to mimic the effect of breathing, the pressure variation is no longer monotonic. We discuss the origin and implications of the modified pressure distribution and attempt to identify asymptotic scaling regimes.

  11. Symmetry of crystals and molecules

    CERN Document Server

    Ladd, Mark


    This book successfully combines a thorough treatment of molecular and crystalline symmetry with a simple and informal writing style. By means of familiar examples the author helps to provide the reader with those conceptual tools necessary for the development of a clear understanding of what are often regarded as 'difficult' topics. Christopher Hammond, University of Leeds This book should tell you everything you need to know about crystal and molecular symmetry. Ladd adopts an integrated approach so that the relationships between crystal symmetry, molecular symmetry and features of chemical interest are maintained and reinforced. The theoretical aspects of bonding and symmetry are also well represented, as are symmetry-dependent physical properties and the applications of group theory. The comprehensive coverage will make this book a valuable resource for a broad range of readers.

  12. Literacy in Limbo? Performance of Two Reading Promotion Schemes in Public Basic Schools in Ghana

    Directory of Open Access Journals (Sweden)

    Kwasi Opoku-Amankwa


    Full Text Available This paper examines two literacy development programmes in basic school classrooms in Ghana: a books scheme for primary schools, mounted by the Ministry of Education in 1998 with support from the Department for International Development, UK, (DfID, and a reading assessment programme (Opoku-Amankwa and Brew-Hammond, 2011 aimed at promoting reading and improving quality of education especially at the basic level. The study reveals that very little is known about the two schemes, pupils’ access to the books is generally poor, and teachers interpret and implement the reading assessment programme in a range of ways according to their understanding. The paper recommends a detailed qualitative and quantitative study of the schemes to assist in future book development and literacy programmes.

  13. Ideomotor signaling: from divining spiritual messages to discerning subconscious answers during hypnosis and hypnoanalysis, a historical perspective. (United States)

    Shenefelt, Philip D


    Ideomotor movements account for non-conscious motions of the hand held pendulum and Ouija board planchette that once were attributed to external spirits. Chevreul and Carpenter in the mid-1800s pioneered our scientific understanding of ideomotor movements. The intention or thought is transmitted to the motor cortex at a subconscious level, coordinated by the cerebellum, and sent down spinal nerves to the appropriate muscles, inducing micromovements not visible to the naked eye but amplified by the hand held pendulum or by the slow ratchet-like cumulative movements of a finger or other body part. This ideomotor phenomenon has been utilized during hypnotic trance to provide nonverbal communication of "yes" or "no" or "I don't want to answer" using finger signals or hand held pendulum. LeCron first used this ideomotor form of communication in conjunction with psychosomatic hypnoanalysis. Cheek expanded and more recently Hammond, Walsh, Ewin and others have refined its use.

  14. Limiting Spectral Distribution of Block Matrices with Toeplitz Block Structure

    CERN Document Server

    Basu, Riddhipratim; Ganguly, Shirshendu; Hazra, Rajat Subhra


    We study two specific symmetric random block Toeplitz (of dimension $k \\times k$) matrices: where the blocks (of size $n \\times n$) are (i) matrices with i.i.d. entries, and (ii) asymmetric Toeplitz matrices. Under suitable assumptions on the entries, their limiting spectral distributions (LSDs) exist (after scaling by $\\sqrt{nk}$) when (a) $k$ is fixed and $n \\to\\infty$ (b) $n$ is fixed and $k\\rightarrow \\infty$ (c) $n$ and $k$ go to $\\infty$ simultaneously. Further the LSD's obtained in (a) and (b) coincide with those in (c) when $n$ or respectively $k$ tends to infinity. This limit in (c) is the semicircle law in case (i). In Case (ii) the limit is related to the limit of the random symmetric Toepiltz matrix as obtained by Bryc et al.(2006) and Hammond and Miller(2005).

    This report describes specific GDSA activities in fiscal year 2015 (FY2015) toward the development of the enhanced disposal system modeling and analysis capability for geologic disposal of nuclear waste. The GDSA framework employs the PFLOTRAN thermal-hydrologic-chemical multi-physics code (Hammond et al., 2011) and the Dakota uncertainty sampling and propagation code (Adams et al., 2013). Each code is designed for massively-parallel processing in a high-performance computing (HPC) environment. Multi-physics representations in PFLOTRAN are used to simulate various coupled processes including heat flow, fluid flow, waste dissolution, radionuclide release, radionuclide decay and ingrowth, precipitation and dissolution of secondary phases, and radionuclide transport through the engineered barriers and natural geologic barriers to a well location in an overlying or underlying aquifer. Dakota is used to generate sets of representative realizations and to analyze parameter sensitivity.

  16. Intuitive Decision Making as the Culmination of Continuing Education: A Theoretical Framework. (United States)

    Payne, Leslie Karns


    The ability to make sound clinical decisions is the cornerstone of excellent nursing care and the goal of continuing nurse educators. Research has revealed that expert nurses make fewer errors in decision making; it also has shown differences in the decision-making process of expert nurses, compared with novice nurses. Specifically, expert nurses report a greater use of intuitive decision making. Accordingly, an important goal for continuing nurse educators is the development of intuitive decision making by nurses. This article proposes a pattern-based, constructivist educational framework that synthesizes Benner's novice to expert (NTE) theory, Damascio's somatic marker hypothesis (SMH), and Hammond's cognitive continuum theory (CCT). This framework provides a foundation for continuing education that fosters the development of intuitive decision making in nurses. Although this framework needs further empirical validation, it is theoretically sound and applicable to all areas of nursing, and its implementation could help reduce errors in decision making by nurses, thus improving patient outcomes.

  18. A spiral model of musical decision-making

    Directory of Open Access Journals (Sweden)

    Daniel eBangert


    Full Text Available This paper describes a model of how musicians make decisions about performing notated music. The model builds on psychological theories of decision-making and was developed from empirical studies of Western art music performance that aimed to identify intuitive and deliberate processes of decision-making, a distinction consistent with dual-process theories of cognition. The model proposes that the proportion of intuitive (Type 1 and deliberate (Type 2 decision-making processes changes with increasing expertise and conceptualises this change as movement along a continually narrowing upward spiral where the primary axis signifies principal decision-making type and the vertical axis marks level of expertise. The model is intended to have implications for the development of expertise as described in two main phases. The first is movement from a primarily intuitive approach in the early stages of learning towards greater deliberation as analytical techniques are applied during practice. The second phase occurs as deliberate decisions gradually become automatic (procedural, increasing the role of intuitive processes. As a performer examines more issues or reconsiders decisions, the spiral motion towards the deliberate side and back to the intuitive is repeated indefinitely. With increasing expertise, the spiral tightens to signify greater control over decision type selection. The model draws on existing theories, particularly Evans’ (2011 Intervention Model of dual-process theories, Cognitive Continuum Theory (Hammond et al., 1987; Hammond, 2007, and Baylor’s (2001 U-shaped model for the development of intuition by level of expertise. By theorising how musical decision-making operates over time and with increasing expertise, this model could be used as a framework for future research in music performance studies and performance science more generally.

  19. The election of Sarah McNutt as the first woman member of the American Neurological Association. (United States)

    Horn, Stacy S; Goetz, Christopher G


    The authors investigated the early women physicians of the New York Infirmary for Women and Children and their role in shaping the career and accomplishments of their student and later colleague, Dr. Sarah J. McNutt. These influences eventually led McNutt to be inducted into the American Neurologic Association (ANA). McNutt was educated at the New York Infirmary for Women and Children by early women physicians including Drs. Elizabeth and Emily Blackwell and Mary Putnam Jacobi. McNutt worked to improve the educational opportunities for practicing physicians and nurses by developing postgraduate lectures and organizations. With her early colleagues she developed the New York Infirmary for Women and Children into a reputable hospital and woman's medical college. One of the consultants to the New York Infirmary for Women and Children was Royal W. Amidon, secretary of the ANA in 1883. McNutt's close association with the Clinical Society of the New York Post Graduate Medical School and Hospital brought her into direct contact with other prominent ANA members including C.L. Dana and W.A. Hammond. In 1884, McNutt was nominated by Amidon and Hammond as the first woman member to the ANA and was elected. Her ANA thesis was Double Infantile Spastic Hemiplegia. McNutt was elected into the ANA at a time when women physicians were first being recognized and included into mainstream medicine. Her historic election acknowledged her accomplishments and highlighted the proactive role of the early ANA in forging new medical policies in the United States.

  20. Numerical Modeling of Thermal-Hydrology in the Near Field of a Generic High-Level Waste Repository (United States)

    Matteo, E. N.; Hadgu, T.; Park, H.


    Disposal in a deep geologic repository is one of the preferred option for long term isolation of high-level nuclear waste. Coupled thermal-hydrologic processes induced by decay heat from the radioactive waste may impact fluid flow and the associated migration of radionuclides. This study looked at the effects of those processes in simulations of thermal-hydrology for the emplacement of U. S. Department of Energy managed high-level waste and spent nuclear fuel. Most of the high-level waste sources have lower thermal output which would reduce the impact of thermal propagation. In order to quantify the thermal limits this study concentrated on the higher thermal output sources and on spent nuclear fuel. The study assumed a generic nuclear waste repository at 500 m depth. For the modeling a representative domain was selected representing a portion of the repository layout in order to conduct a detailed thermal analysis. A highly refined unstructured mesh was utilized with refinements near heat sources and at intersections of different materials. Simulations looked at different values for properties of components of the engineered barrier system (i.e. buffer, disturbed rock zone and the host rock). The simulations also looked at the effects of different durations of surface aging of the waste to reduce thermal perturbations. The PFLOTRAN code (Hammond et al., 2014) was used for the simulations. Modeling results for the different options are reported and include temperature and fluid flow profiles in the near field at different simulation times. References:G. E. Hammond, P.C.

  2. Innovative clean coal technology: 500 MW demonstration of advanced wall-fired combustion techniques for the reduction of nitrogen oxide (NOx) emissions from coal-fired boilers. Final report, Phases 1 - 3B

    Energy Technology Data Exchange (ETDEWEB)



    This report presents the results of a U.S. Department of Energy (DOE) Innovative Clean Coal Technology (ICCT) project demonstrating advanced wall-fired combustion techniques for the reduction of nitrogen oxide (NOx) emissions from coal-fired boilers. The project was conducted at Georgia Power Company`s Plant Hammond Unit 4 located near Rome, Georgia. The technologies demonstrated at this site include Foster Wheeler Energy Corporation`s advanced overfire air system and Controlled Flow/Split Flame low NOx burner. The primary objective of the demonstration at Hammond Unit 4 was to determine the long-term effects of commercially available wall-fired low NOx combustion technologies on NOx emissions and boiler performance. Short-term tests of each technology were also performed to provide engineering information about emissions and performance trends. A target of achieving fifty percent NOx reduction using combustion modifications was established for the project. Short-term and long-term baseline testing was conducted in an {open_quotes}as-found{close_quotes} condition from November 1989 through March 1990. Following retrofit of the AOFA system during a four-week outage in spring 1990, the AOFA configuration was tested from August 1990 through March 1991. The FWEC CF/SF low NOx burners were then installed during a seven-week outage starting on March 8, 1991 and continuing to May 5, 1991. Following optimization of the LNBs and ancillary combustion equipment by FWEC personnel, LNB testing commenced during July 1991 and continued until January 1992. Testing in the LNB+AOFA configuration was completed during August 1993. This report provides documentation on the design criteria used in the performance of this project as it pertains to the scope involved with the low NOx burners and advanced overfire systems.

    Deep electromagnetic investigation, using magnetotelluric (MT) and Deep Electrical Resistivity Tomography (DERT) methods, has been carried out across the Aterno Valley, in the epicentral area of April 6, 2009 (Mw=6.3) Abruzzo earthquake, with the aim to study the geological and structural setting of the subsurface. The L'Aquila Basin is a 60 Km long intermountain depression of the Central Apennines, with a NW-SE-trending, bounded to SW by Monti Sirente-Monte Ocre and by Gran Sasso to NE. This depression is filled in Quaternary continental sediments of the Aterno River while the bedrock is composed by Mesocenozoic calcareous of platform. In the middle part of the basin, from Bagno (SW) to Paganica village (NE), along a profile about 9 km long were carried out 10 MT soundings with site separations of about of 1 km. The acquisition of MT data were obtained with MT24-LF systems (Schlumberger/EMI). The frequency of data recording was set to 6.25 Hz for at least 24 hours and during night-time we launched high frequency sampling acquisition events (500 Hz) for at least 2 hour. Time series data were analyzed using the processing based on Egbert's robust code (Egbert, 1997) to compute estimates of the MT transfer function in the period range 0.00931-238.313 s. Applying an inversion 2D model we have obtained the distribution resistivity of subsoil, as function of depth. The apparent resistivity and phase for TE and TM mode (in all investigated period range) were inverted by using an algorithm developed by Rodi & Mackie, 2001. Almost coincident with MT profile, a DERT with "dipole-dipole" array configuration has been carried out along a profile of 8Km, using 21 stations with an electrode spacing of 400 m and a maximum distance between current and potential probes 7-8 times the basic spacing. In this way, the electrode array geometry allows us to obtain a an exploration depth of about 900 m. The acquisition system consists of a transmitting stations which injects the current

    Wong, J. [Johns Hopkins University: Managing the Relationship (United States)


    Academic-industrial collaborations are playing an increasingly prominent role in medical physics research. Successful partnerships have enabled truly translational, benchtop-to-bedside research that has significantly and positively impacted our field. Given the current flat or depleting trends in federal funding, and the increasing emphasis in the medical physics community on demonstrating translatability, efficacy, and safety prior to widespread clinical use, it is anticipated that such partnerships will become ever more important in advancing our field. In the future, it is likely that neither academia alone, nor industry alone, will be able to bring significant innovation to successfully impact patient care in radiotherapy. Such innovation will require partnership and symbiosis through the lifetime of the project. This symposium is aimed at professionals from academia and the industry who are interested in either initiating new collaborations or maintaining and improving existing partnerships. We will hear from four thought leaders from industry and academia on critical aspects of building and maintaining successful academic-industrial research partnerships. The following topics will be addressed: 1. Motivations: The industry perspective [Kevin Brown, Elekta] What goes into the development of a company’s R&D roadmap What are the motivations and expectations of the industry from academic partners How can academics make a successful pitch by identifying projects aligned with a company’s roadmap Why are some relationships successful and some not Milestones and progress reports - Why do we need them 2. Motivations: The academic perspective [T. Rock Mackie, Univ. of Madison, WI; Tomotherapy] What are the motivations and expectations of academic partners from the industry What are the cultural differences in academia vs industry on sharing information, exchanging ideas Partnership or entrepreneurship? When does each option make sense 3. Industrial Grants and

  5. Dynamics of change in the practice of female genital cutting in Senegambia: Testing predictions of social convention theory (United States)

    Shell-Duncan, Bettina; Wander, Katherine; Hernlund, Ylva; Moreau, Amadou


    Recent reviews of intervention efforts aimed at ending female genital cutting (FGC) have concluded that progress to date has been slow, and call for more efficient programs informed by theories on behavior change. Social convention theory, first proposed by Mackie (1996), posits that in the context of extreme resource inequality, FGC emerged as a means of securing a better marriage by signaling fidelity, and subsequently spread to become a prerequisite for marriage for all women. Change is predicted to result from coordinated abandonment in intermarrying groups so as to preserve a marriage market for uncircumcised girls. While this theory fits well with many general observations of FGC, there have been few attempts to systematically test the theory. We use data from a three year mixed-method study of behavior change that began in 2004 in Senegal and The Gambia to explicitly test predictions generated by social convention theory. Analyses of 300 in-depth interviews, 28 focus group discussions, and survey data from 1220 women show that FGC is most often only indirectly related to marriageability via concerns over preserving virginity. Instead we find strong evidence for an alternative convention, namely a peer convention. We propose that being circumcised serves as a signal to other circumcised women that a girl or woman has been trained to respect the authority of her circumcised elders and is worthy of inclusion in their social network. In this manner, FGC facilitates the accumulation of social capital by younger women and of power and prestige by elder women. Based on this new evidence and reinterpretation of social convention theory, we suggest that interventions aimed at eliminating FGC should target women’s social networks, which are intergenerational, and include both men and women. Our findings support Mackie’s assertion that expectations regarding FGC are interdependent; change must therefore be coordinated among interconnected members of social networks

  6. New Empirical Potential Energy Functions for the Heavier Homonuclear Rare Gas Pairs: {Ne}_2, {Ar}_2, {Kr}_2, and {Xe}_2 (United States)

    Myatt, Philip Thomas; Baker, Matthew T.; Kang, Ju-Hee; Escobar Moya, Andres; McCourt, Frederick R. W.; Le Roy, Robert J.


    The many decades of work on determining accurate analytic pair potentials for rare gas dimers from experimental data focussed largely on the use of bulk non-ideal gas and collisional properties, with the use of spectroscopic data being somewhat of an afterthought, for testing the resulting functions. This was a natural result of experimental challenges, as the very weak binding of ground-state rare gas pairs made high resolution spectroscopy a relatively late arrival as a practical tool in this area. However, we believe that it is now time for a comprehensive reassessment. Following up on a preliminary report at this meeting five years ago, this paper describes work to determine a new generation of empirical potential energy functions for the four heavier (i.e., not involving He) homonuclear rare gas pairs from direct fits to all available spectroscopic, pressure virial, and acoustic virial coefficient data, with the resulting functions being `tuned' by comparisons with available thermal transport property data: viscosity, mass diffusion and thermal diffusion, and thermal conductivity data, and tested against the best available ab initio potentials. The resulting functions are everywhere smooth and differentiable to all orders, incorporate the correct (damped) theoretical inverse-power long-range behaviour, and have sensible short-range extrapolation behaviour.

  7. Using mouse models to understand normal and abnormal urogenital tract development. (United States)

    Mendelsohn, Cathy


    Removal of toxic substances from the blood depends on patent connections between the kidneys, ureters and bladder that are established when the ureter is transposed from its original insertion site in the Wolffian duct, to the bladder, its final insertion site. The Ureteral Bud Theory of Mackie and Stephens suggests that repositioning of the ureter orifice occurs as the trigone forms from the common nephric duct (CND), the caudal-most Wolffian duct segment. According to this model, insertion of the CND into the bladder and its expansion into the trigone both repositions the ureter in the bladder and enables it to separate from the Wolffian duct. The availability of new mouse models has enabled to re-examine this hypothesis using morphological analysis and lineage studies to follow the fate of the ureter and CND during the maturation process. We find that in contrast to what has been previously thought, the CND does not differentiate into the trigone but instead, undergoes apoptosis, a step that enables the ureter to separate from the Wolffian duct. Apoptosis occurs as the CND and ureter merge with the urogenital sinus positioning the ureter orifice at a site close to the Wolffian duct. Finally, expansion of the bladder moves the ureter orifice which is now fused with epithelium to its final position which is at the bladder neck. Interestingly, CND apoptosis appears to depend on close proximity to the bladder, suggesting that the bladder may be a source of signals that induce cell death. Together, these studies provide new insights into the normal process of ureter maturation, and shed light on possible causes of obstruction and reflux, ureteral abnormalities that affect 1-2% of the human population.

  8. SCOR WG-131: The Legacy of in situ Iron Enrichment Experiments - Data Compilation and Modeling (United States)

    Boyd, Philip W.; Bakker, Dorothee C. E.; Wg-131, Scor


    Working Group 131 (WG-131) of the Scientific Committee on Oceanic Research (SCOR) has these aims: 1) Data compilation. Assembling in a common open-access database the metadata and data of the in situ iron fertilization experiments, ranging from surface water and water column data on physical, chemical and biological parameters, to biogeochemical rate processes and incubation experiments 2) Modeling and data synthesis of specific aspects of two or more such experiments for various topics, such as physical mixing, phytoplankton productivity, overall ecosystem functioning, iron chemistry, carbon budgeting, nutrient uptake ratios, and combinations of these variables and processes. Over the last 24 months SCOR WG-131 participants, in particular Doug Mackie, have liased with Cyndy Chandler and Steve Gegg at the Biological and Chemical Oceanography Data Management Office (BCO-DMO; to pull together a relational database that spans data from IronEx I in 1993 to SEEDS II in 2004. The BCO-DMO database currently contains data sets for IronEx I, IronEx II, SOIREE, SEEDS I, SEEDS II, SERIES, SOFeX-North and SOFeX-South. The BCO-DMO data base also has a link to the publicly available EisenEx data, which are stored at the World Data Center for Marine Environmental Sciences (WDC-MARE, We hope to launch the BCO-DMO database at a side meeting on the afternoon of Sunday 21 February 2010 before the Ocean Sciences Meeting in Portland. The relational BCO-DMO database permits intercomparisons of data, thus allowing for exciting and novel opportunities for data synthesis and modeling, from 1-dimensional simple biological models through to complex 3-dimensional models. Scientists interested in such work are invited to contact the chairs of WG-131.

  10. Brightness Variations of Sun-like Stars: The Mystery Deepens - Astronomers facing Socratic "ignorance" (United States)


    An extensive study made with ESO's Very Large Telescope deepens a long-standing mystery in the study of stars similar to the Sun. Unusual year-long variations in the brightness of about one third of all Sun-like stars during the latter stages of their lives still remain unexplained. Over the past few decades, astronomers have offered many possible explanations, but the new, painstaking observations contradict them all and only deepen the mystery. The search for a suitable interpretation is on. "Astronomers are left in the dark, and for once, we do not enjoy it," says Christine Nicholls from Mount Stromlo Observatory, Australia, lead author of a paper reporting the study. "We have obtained the most comprehensive set of observations to date for this class of Sun-like stars, and they clearly show that all the possible explanations for their unusual behaviour just fail." The mystery investigated by the team dates back to the 1930s and affects about a third of Sun-like stars in our Milky Way and other galaxies. All stars with masses similar to our Sun become, towards the end of their lives, red, cool and extremely large, just before retiring as white dwarfs. Also known as red giants, these elderly stars exhibit very strong periodic variations in their luminosity over timescales up to a couple of years. "Such variations are thought to be caused by what we call 'stellar pulsations'," says Nicholls. "Roughly speaking, the giant star swells and shrinks, becoming brighter and dimmer in a regular pattern. However, one third of these stars show an unexplained additional periodic variation, on even longer timescales - up to five years." In order to find out the origin of this secondary feature, the astronomers monitored 58 stars in our galactic neighbour, the Large Magellanic Cloud, over two and a half years. They acquired spectra using the high resolution FLAMES/GIRAFFE spectrograph on ESO's Very Large Telescope and combined them with images from other telescopes [1

  11. Hazards Response of Energetic Materials - Initiation Mechanisms, Experimental Characterization, and Development of Predictive Capability

    Energy Technology Data Exchange (ETDEWEB)

    Maienschein, J; Nichols III, A; Reaugh, J; McClelland, M; Hsu, P C


    We present our approach to develop a predictive capability for hazards -- thermal and non-shock impact -- response of energetic material systems based on: (A) identification of relevant processes; (B) characterization of the relevant properties; (C) application of property data to predictive models; and (D) application of the models into predictive simulation. This paper focuses on the first two elements above, while a companion paper by Nichols et al focuses on the final two elements. We outline the underlying mechanisms of hazards response and their interactions, and present our experimental work to characterize the necessary material parameters, including thermal ignition, thermal and mechanical properties, fracture/fragmentation behavior, deflagration rates, and the effect of material damage. We also describe our validation test, the Scaled Thermal Explosion Experiment. Finally, we integrate the entire collection of data into a qualitative understanding that is useful until such time as the predictive models become available.

    Une, T; Nakajima, R; Otani, T; Katami, K; Osada, Y; Otani, M


    Ofloxacin, a new pyridone-carboxylic acid derivative, was evaluated in experimental syphilis in rabbits in comparison with penicillin G. Experimental syphilis was established by intradermal injection of Treponema pallidum subsp. pallidum Nichols. Ten days after infection, the dermal lesions were characterized by syphilitic papula accompanied with central necrosis. These animals were subsequently treated either with ofloxacin twice a day at an oral dose of 10 mg/kg or with penicillin G once a day at an intramuscular dose of 10,000 U/kg for 21 consecutive days. In penicillin G-treated animals, the dermal lesions became smaller as early as day 3 of treatment and almost disappeared during the therapy. In marked contrast to remarkable efficacy of penicillin G was further development of the lesions in ofloxacin-treated animals, showing no difference in pathological manifestations as compared to untreated animals. The results of nontreponemal serologic test correlated well with the response of animals to treatment.

    Physical Review was founded at Cornell University in 1893, by two professors, Edward L. Nichols and Ernest Merritt. Both were educated in Germany, and were familiar with the differences in publications abroad. They were enthusiastic about the idea of an American publication devoted entirely to physics. They fortunately had the full support of the then President of Cornell, J. Gould Shurman, who arranged for an initial grant of 500, and eventually, for a first year total of 2500. The founding editors were soon joined by Frederick Bedell, who remained an Editor into the 1920's. This talk will follow the progress (and otherwise) of the journal through the formation of the American Physical Society in 1899 and the transfer of its operation from Cornell to the APS in 1913.

    Full Text Available Many instruments for psychological assessment are originally developed in different languages than the ones found in the countries where they are used (Butcher, Lim, & Nezami, 1998; Nichols, Padilla, & Gomez-Maqueo, 2000. Some of these instruments have been widely used, in particular those intended to assess personality from a five-factor personality model. The present study aims to address potential cultural differences between Romania and Italy in regard to the Big Five Questionnaire – 2 (BFQ-2, Caprara, Barbaranelli & Borgogni, 1993, based on national normative validation samples of 4578 participants (Italy and 2100 participants (Romania. Data obtained show significant differences between the two cultures on most of the BFQ-2 scales and subscales, excepting the conscientiousness factor and the cooperation subscale.

  18. Measuring nebular temperatures: the effect of new collision strengths with equilibrium and kappa-distributed electron energies

    CERN Document Server

    Nicholls, David C; Sutherland, Ralph S; Kewley, Lisa J; Palay, Ethan


    In this paper we develop tools for observers to use when analysing nebular spectra for temperatures and metallicities, with two goals: to present a new, simple method to calculate equilibrium electron temperatures for collisionally excited line flux ratios, using the latest atomic data; and to adapt current methods to include the effects of possible non-equilibrium '{\\kappa}' electron energy distributions. Adopting recent collision strength data for [O iii], [S iii], [O ii], [S ii], and [N ii], we find that existing methods based on older atomic data seriously overestimate the electron temperatures, even when considering purely Maxwellian statistics. If {\\kappa} distributions exist in H ii regions and planetary nebulae as they do in solar system plasmas, it is important to investigate the observational consequences. This paper continues our previous work on the {\\kappa} distribution (Nicholls et al. 2012). We present simple formulaic methods that allow observers to (a) measure equilibrium electron temperature...

    The program established a collaborative process with domestic industries for the purpose of sharing Navy-developed technology. Private sector businesses were educated so as to increase their awareness of the vast amount of technologies that are available, with an initial focus on technology applications that are related to the Hydrogen, Fuel Cells and Infrastructure Technologies (Hydrogen) Program of the U.S. Department of Energy. Specifically, the project worked to increase industry awareness of the vast technology resources available to them that have been developed with taxpayer funding. NAVSEA-Carderock and the Houston Advanced Research Center teamed with Nicholls State University to catalog NAVSEA-Carderock unclassified technologies, rated the level of readiness of the technologies and established a web based catalog of the technologies. In particular, the catalog contains technology descriptions, including testing summaries and overviews of related presentations.

  20. Techniques of structural family assessment: a qualitative analysis of how experts promote a systemic perspective. (United States)

    Nichols, Michael; Tafuri, Sydney


    The trajectory of assessment in structural family therapy moves from a linear perspective, in which problems are located in the identified patient, to an interactional perspective, in which problems are seen as involving other members of the family. Minuchin, Nichols, & Lee (2007) developed a 4-step model for assessing couples and families consisting of: (1) broadening the definition of the presenting complaint to include its context, (2) identifying problem-maintaining interactions, (3) a structurally focused exploration of the past, and (4) developing a shared vision of pathways to change. To study how experts actually implement this model, judges coded video recordings of 10 initial consultations conducted by three widely recognized structural family therapists. Qualitative analyses identified 25 distinct techniques that these clinicians used to challenge linear thinking and move families toward a systemic understanding of their problems. We discuss and locate these techniques in the framework of the 4-step model.

  2. Examining a negative halo effect to anabolic steroids users through perceived achievement goals, sportspersonship orientations, and aggressive tendencies. (United States)

    Chantal, Yves; Bernache-Assollant, Iouri; Schiano-Lomoriello, Sandrine


    We investigated the social image of anabolic steroids (AS) users grounding our analysis on the achievement goal theory of Nicholls. Our main goal was to explore how an athlete's acceptance of AS use would impact on the way that athlete will be perceived by others. Non-AS-using participants reacted to one of two scenarios portraying a male athlete either accepting or refusing to engage in drug use behavior. The results suggested that the acceptance of anabolic steroids yielded an unfavorable social image--perceivers inferred a predominant ego orientation to characterize the AS-user's motivation as well as weaker sportspersonship and a stronger proclivity for reactive aggression than instrumental aggression. Moreover, the analyses did not yield significant gender or interaction effects. Finally, those findings are commented in view of methodological shortcomings and of the perspectives that they may offer for future research concerning the motivational aspects of the social perceptions of drug use in sport.

  3. Fuzzy attitude control of solar sail via linear matrix inequalities (United States)

    Baculi, Joshua; Ayoubi, Mohammad A.


    This study presents a fuzzy tracking controller based on the Takagi-Sugeno (T-S) fuzzy model of the solar sail. First, the T-S fuzzy model is constructed by linearizing the existing nonlinear equations of motion of the solar sail. Then, the T-S fuzzy model is used to derive the state feedback controller gains for the Twin Parallel Distributed Compensation (TPDC) technique. The TPDC tracks and stabilizes the attitude of the solar sail to any desired state in the presence of parameter uncertainties and external disturbances while satisfying actuator constraints. The performance of the TPDC is compared to a PID controller that is tuned using the Ziegler-Nichols method. Numerical simulation shows the TPDC outperforms the PID controller when stabilizing the solar sail to a desired state.

    This paper presents the application of the proportional-integral-derivative (PID) controller to the flight control system (FCS) for two-dimensional (2D) differential geometric (DG) guidance and control problem. In particular,the performance of the designed FCS is investigated. To this end, the commanded angle-of-attack is firstly developed in the time domain using the classical DG formulations. Then, the classical PID controller is introduced to develop a FCS so as to form the 2D DG guidance and control system, and the PID controller parameters are determined by the Ziegler-Nichols method as well as the Routh-Hurwitz stability algorithm to guarantee the convergence of the system error. The results demonstrate that the designed controller yields a fast responding system, and the resulting DG guidance and control system is viable and effective in a realistic missile defense engagement.

  6. Ancient blue oaks reveal human impact on San Francisco Bay salinity (United States)

    Stahle, David W.; Therrell, Matthew D.; Cleaveland, Malcolm K.; Cayan, Daniel R.; Dettinger, Michael D.; Knowles, Noah


    San Francisco Bay is one of the most important estuaries on the west coast of the Americas. Its water quality is controlled primarily by streamflow from the Sacramento and San Joaquin rivers. In fact, freshwater inflow from the Sacramento-San Joaquin Delta explains 86% of the salinity variability at the mouth of the San Francisco Bay estuary [Peterson et al., 1989]. The massive diversion of streamflow by the California State Water Project and the Central Valley Project, part of the largest manmade water control system on Earth [Reisner, 1988], has raised salinity in the estuary on daily, seasonal, and annual timescales [Nichols et al., 1986; Peterson et al., 1989].

    Full Text Available The family Loricariidae with about 690 species divided into six subfamilies, is one of the world’s largest fish families. Cytogenetic studies conducted in the family showed that among 90 species analyzed the diploid number ranges from 2n=38 in Ancistrus sp. to 2n=96 in Hemipsilichthys gobio Luetken, 1874. In the present study, fluorescence in situ hybridization (FISH was employed to determine the chromosomal localization of the 18S rDNA gene in four suckermouth armoured catfishes: Kronichthys lacerta (Nichols, 1919, Pareiorhaphis splendens (Bizerril, 1995, Liposarcus multiradiatus (Hancock, 1828 and Hypostomus prope plecostomus (Linnaeus, 1758. All species analyzed showed one chromosome pair with 18S rDNA sequences, as observed in the previous Ag-NORs analyses. The presence of size and numerical polymorphism was observed and discussed, with proposing a hypothesis of the Ag-NOR evolution in Loricariidae.

  8. Design and Field Implementation of Auto Tuned Virtual Instrumentation Corrosion Controller (United States)

    Gopalakrishnan, J.; Agnihotri, Ganga; Deshpande, D. M.


    Corrosion in underground metallic pipeline leads to leakage which is hazardous when oil/natural gas is transported. Rate of corrosion in metal pipeline can be controlled by impressing dc current to the gas pipeline and thereby making metal pipeline to act as cathode of corrosion cell. Proportional integral controllers are used in impressed current cathodic protection application; tuning of proportional and integral constants of these controllers requires expertise. Step open, step close and relay tuning methods are compared; relay tuning provided better results for cathodic protection application. Ziegler-Nichols tuning formulas are used to select tuning parameters based on loop response. Virtual instrumentation is used for design, development, testing and field implementation of auto tuned PI controller. Proposed auto tuned proportional integral impressed current cathodic protection controller precisely controls corrosion in pipeline by selecting optimum proportional and integral constants. Controller effectiveness is cross verified using electrical resistance probe.

    The hazardous volatile compounds from chicken manure in chicken barn are potentially to be a health threat to the farm animals and workers. Ammonia (NH3) and hydrogen sulphide (H2S) produced in chicken barn are influenced by climate changes. The Electronic Nose (e-nose) is used for the barn's air, temperature and humidity data sampling. Simple Linear Regression is used to identify the correlation between temperature-humidity, humidity-ammonia and ammonia-hydrogen sulphide. MATLAB Simulink software was used for the sample data analysis using PID controller. Results shows that the performance of PID controller using the Ziegler-Nichols technique can improve the system controller to control climate in chicken barn.

    This paper describes the modeling and the tuning of the top temperature control system of a combined fractionater of a Delayed Coke Unit of Gabriel Passos Refinery, located at Betim, MG, Brazil. The ARX model of the process was identified using MATLAB{sup TM}. Simulations with this model was used to find PID parameters of the controller of this temperature using Ziegler- Nichols close-loop methodology. The tuning was tested in the model and, after some adjustments, it was set into the actual controller. This paper shows the behave of the actual system with the two adjustments the previous one and the new one. Results pointed the change from the previous tuning to the new one got from this work.

  11. [The string of Einthoven's string galvanometer]. (United States)

    Wyers, P J


    The Dutch physiologist Willem Einthoven (1860-1927) published in 1901 his construction of a string galvanometer. With this apparatus he opened the era for electrocardiography. As the quality of his instrument largely depended on the string of the string galvanometer it is surprising to note that in his publications Einthoven never mentioned the exact way of producing the string. However, Einthoven's hand written laboratory notes are preserved at the Museum Boerhaave in Leiden. From these notes it comes clear what problems Einthoven had with the string. To get a very thin thread of quarts he first used the method of shooting the thread as was described by Boys (1887), later the blowing method of Nichols (1894). The silvering of the thread was done first chemically, later by cathode spray. In all cases premature breaking of the thread was a nuisance. Because of these failures Einthoven might have decided not to publish any details.

  12. A new PID controller design for automatic generation control of hydro power systems

    Energy Technology Data Exchange (ETDEWEB)

    Khodabakhshian, A.; Hooshmand, R. [Electrical Engineering Department, University of Isfahan (Iran)


    This paper presents a new robust PID controller for automatic generation control (AGC) of hydro turbine power systems. The method is mainly based on a maximum peak resonance specification that is graphically supported by the Nichols chart. The open-loop frequency response curve is tangent to a specified ellipse and this makes the method to be efficient for controlling the overshoot, the stability and the dynamics of the system. Comparative results of this new load frequency controller with a conventional PI one and also with another PID controller design tested on a multimachine power system show the improvement in system damping remarkably. The region of acceptable performance of the new PID controller covers a wide range of operating and system conditions. (author)

  13. A new autotuning algorithm for PID controllers using dead-beat format. (United States)

    Bandyopadhyay, R; Patranabis, D


    A novel algorithm for PID controllers based on dead-beat control and fuzzy inference mechanism is presented in this paper. The proposition is an extension of the work by the authors where the PI form of the algorithm was presented. The inclusion of the derivative term makes the method suitable for application in all types of processes including the ones having high rate disturbances. The proposed algorithm seems to be a complete and generalized PID autotuner as can be seen by the simulated and experimental results. In all the cases the method shows substantial improvement over the controller tuned with Ziegler Nichol's formula and the PI controller proposed in R. Bandyopadhyay, D.

  14. Discrete control systems

    CERN Document Server

    Okuyama, Yoshifumi


    Discrete Control Systems establishes a basis for the analysis and design of discretized/quantized control systemsfor continuous physical systems. Beginning with the necessary mathematical foundations and system-model descriptions, the text moves on to derive a robust stability condition. To keep a practical perspective on the uncertain physical systems considered, most of the methods treated are carried out in the frequency domain. As part of the design procedure, modified Nyquist–Hall and Nichols diagrams are presented and discretized proportional–integral–derivative control schemes are reconsidered. Schemes for model-reference feedback and discrete-type observers are proposed. Although single-loop feedback systems form the core of the text, some consideration is given to multiple loops and nonlinearities. The robust control performance and stability of interval systems (with multiple uncertainties) are outlined. Finally, the monograph describes the relationship between feedback-control and discrete ev...

  15. Quantum Lie theory a multilinear approach

    CERN Document Server

    Kharchenko, Vladislav


    This is an introduction to the mathematics behind the phrase “quantum Lie algebra”. The numerous attempts over the last 15-20 years to define a quantum Lie algebra as an elegant algebraic object with a binary “quantum” Lie bracket have not been widely accepted. In this book, an alternative approach is developed that includes multivariable operations. Among the problems discussed are the following: a PBW-type theorem; quantum deformations of Kac--Moody algebras; generic and symmetric quantum Lie operations; the Nichols algebras; the Gurevich--Manin  Lie algebras;  and Shestakov--Umirbaev  operations for the Lie theory of nonassociative products.  Opening with an introduction for beginners and continuing as a textbook for graduate students in physics and mathematics, the book can also be used as a reference by more advanced readers. With the exception of the introductory chapter, the content of this monograph has not previously appeared in book form.

  16. PID controller tuning for the first-order-plus-dead-time process model via Hermite-Biehler theorem. (United States)

    Roy, Anindo; Iqbal, Kamran


    This paper discusses PID stabilization of a first-order-plus-dead-time (FOPDT) process model using the stability framework of the Hermite-Biehler theorem. The FOPDT model approximates many processes in the chemical and petroleum industries. Using a PID controller and first-order Padé approximation for the transport delay, the Hermite-Biehler theorem allows one to analytically study the stability of the closed-loop system. We derive necessary and sufficient conditions for stability and develop an algorithm for selection of stabilizing feedback gains. The results are given in terms of stability bounds that are functions of plant parameters. Sensitivity and disturbance rejection characteristics of the proposed PID controller are studied. The results are compared with established tuning methods such as Ziegler-Nichols, Cohen-Coon, and internal model control.

  17. Advanced Fireworks Algorithm and Its Application Research in PID Parameters Tuning

    Directory of Open Access Journals (Sweden)

    Jun-jie Xue


    Full Text Available Proportional-Integral-Derivative (PID controller is one of the most widely used controllers for its property of simplicity and practicability. In order to design high-quality performances PID controllers, an Advanced Fireworks (AFW algorithm based on self-adaption principle and bimodal Gaussian function is proposed, which is built to optimize the PID controller by parameters tuning. Firstly, a compound index of optimization performance is formulated, and then the extremal optimization method of PID control system is proposed. Secondly, a PID parameters tuning model combined with AFW is built. At last, 5 typical transfer functions are simulated to obtain optimal parameters by AFW and contrast tuning method, such as Ziegler-Nichols method, Enhanced Fireworks (EFW algorithm, and Particle Swarm Optimization (PSO. Simulation results show that AFW are effective and are easily implemented methods to solve PID control problems of different transfer functions.

  18. PID Daylight Control System

    Directory of Open Access Journals (Sweden)

    Horaţiu Ştefan Grif


    Full Text Available The paper describes the implementation and the tuning of a digital PID controller used in a daylight control application. Due to the fact that the process is unknown, an experimental method, Ziegler-Nichols, for the tuning of the PID controller was used. The obtained PID parameters do not offer a good behavior of the ALCS. To improve the performances of the ALCS, supplementary tuning of the PID parameters, via step response analysis, was made. The step response acquiring and analysis may have an expensive time cost. To avoid the time cost the present paper offers an algorithm which guide the designer to chose, in a slight manner, not only a set but a set family of the PID parameters for which the ALCS has a good behavior. Also, the algorithm presents the way how the ALCS user can set his desired ALCS speed reaction to the daylight variations.

  19. PI controller design of a wind turbine: evaluation of the pole-placement method and tuning using constrained optimization

    DEFF Research Database (Denmark)

    Mirzaei, Mahmood; Tibaldi, Carlo; Hansen, Morten Hartvig


    PI/PID controllers are the most common wind turbine controllers. Normally a first tuning is obtained using methods such as pole-placement or Ziegler-Nichols and then extensive aeroelastic simulations are used to obtain the best tuning in terms of regulation of the outputs and reduction of the loads....... In the traditional tuning approaches, the properties of different open loop and closed loop transfer functions of the system are not normally considered. In this paper, an assessment of the pole-placement tuning method is presented based on robustness measures. Then a constrained optimization setup is suggested...... to automatically tune the wind turbine controller subject to robustness constraints. The properties of the system such as the maximum sensitivity and complementary sensitivity functions (Ms and Mt), along with some of the responses of the system, are used to investigate the controller performance and formulate...

  20. Radial Basis Function Neural Network-based PID model for functional electrical stimulation system control. (United States)

    Cheng, Longlong; Zhang, Guangju; Wan, Baikun; Hao, Linlin; Qi, Hongzhi; Ming, Dong


    Functional electrical stimulation (FES) has been widely used in the area of neural engineering. It utilizes electrical current to activate nerves innervating extremities affected by paralysis. An effective combination of a traditional PID controller and a neural network, being capable of nonlinear expression and adaptive learning property, supply a more reliable approach to construct FES controller that help the paraplegia complete the action they want. A FES system tuned by Radial Basis Function (RBF) Neural Network-based Proportional-Integral-Derivative (PID) model was designed to control the knee joint according to the desired trajectory through stimulation of lower limbs muscles in this paper. Experiment result shows that the FES system with RBF Neural Network-based PID model get a better performance when tracking the preset trajectory of knee angle comparing with the system adjusted by Ziegler- Nichols tuning PID model.

  1. Design of PID controllers in double feedback loops for SISO systems with set-point filters. (United States)

    Vijayan, V; Panda, Rames C


    A PID controller is widely used to control industrial processes that are mostly open loop stable or unstable. Selection of proper feedback structure and controller tuning helps to improve the performance of the loop. In this paper a double-feedback loop/method is used to achieve stability and better performance of the process. The internal feedback is used for stabilizing the process and the outer loop is used for good setpoint tracking. An internal model controller (IMC) based PID method is used for tuning the outer loop controller. Autotuning based on relay feedback or the Ziegler-Nichols method can be used for tuning an inner loop controller. A tuning parameter (λ) that is used to tune IMC-PID is used as a time constant of a setpoint filter that is used for reducing the peak overshoot. The method has been tested successfully on many low order processes.

  2. Mathematical approaches to comparative linguistics‡ (United States)

    Warnow, Tandy


    The inference of the evolutionary history of a set of languages is a complex problem. Although some languages are known to be related through descent from common ancestral languages, for other languages determining whether such a relationship holds is itself a difficult problem. In this paper we report on new methods, developed by linguists Johanna Nichols (University of California, Berkeley), Donald Ringe and Ann Taylor (University of Pennsylvania, Philadelphia), and me, for answering some of the most difficult questions in this domain. These methods and the results of the analyses based on these methods were presented in November 1995 at the Symposium on the Frontiers of Science held by the National Academy of Sciences.

  3. Limitations of Feedback, Feedforward and IMC Controller for a First Order Non-Linear Process with Dead Time

    Directory of Open Access Journals (Sweden)

    Maruthai Suresh


    Full Text Available A nonlinear process, the heat exchanger whose parameters vary with respect to the process variable, is considered. The time constant and gain of the chosen process vary as a function of temperature. The limitations of the conventional feedback controller tuned using Ziegler-Nichols settings for the chosen process are brought out. The servo and regulatory responses through simulation and experimentation for various magnitudes of set-point changes and load changes at various operating points with the controller tuned only at a chosen nominal operating point are obtained and analyzed. Regulatory responses for output load changes are studied. The efficiency of feedforward controller and the effects of modeling error have been brought out. An IMC based system is presented to understand clearly how variations of system parameters affect the performance of the controller. The present work illustrates the effectiveness of Feedforward and IMC controller.

  4. The Parameter Estimation and Stability Improvement of the Brushless DC Motor

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Cherl Jin [Halla University (Korea, Republic of); Im, Tae Bin [Korea Electronics Technology Institute (Korea, Republic of)


    Generally, the digital controller has many advantages such as high precision, robustness to electrical noise, capability of flexible programming and fast response to the load variation. In this study, we have established proper mathematical equivalent model of brushless DC (BLDC) motor and estimated the motor parameter by means of the back-emf measurement as being the step input to the controlled target BLDC motor. And the validity of proposed estimation method is confirmed by the test result of step response. As well, we have designed the reasonable digital controller as a consequence of the root locus method which is obtained from the open-loop transfer function of BLDC motor with hall sensor, and the determination of control gain for variable speed control. Here, revised Ziegler-Nichols tuning method is applied for the proper digital gain establishment, and the system stability is verified by the frequency domain analysis with Bode-plot and experimentation.

  5. A case study of cumulus formation beneath a stratocumulus sheet: Its structure and effect on boundary layer budgets (United States)

    Barlow, Roy W.; Nicholls, S.


    On several occasions during the FIRE Marine Stratocumulus IFO off the California coast, small cumulus were observed to form during the morning beneath the main stratocumulus (Sc) deck. This occurs in the type of situation described by Turton and Nicholls (1987) in which there is insufficient generation of turbulent kinetic energy (TKE) from the cloudtop or the surface to sustain mixing throughout the layer, and a separation of the surface and cloud layers occurs. The build up of humidity in the surface layer allows cumuli to form, and the more energetic of these may penetrate back into the Sc deck, reconnecting the layers. The results presented were collected by the UKMO C-130 aircraft flying in a region where these small cumulus had grown to the extent that they had penetrated into the main Sc deck above. The structure of these penetrative cumulus are examined and their implications on the layer flux and radiation budget discussed.

  6. Preliminary mixed-layer model results for FIRE marine stratocumulus IFO conditions (United States)

    Barlow, R.; Nicholls, S.


    Some preliminary results from the Turton and Nicholls mixed layer model using typical FIRE boundary conditions are presented. The model includes entrainment and drizzle parametrizations as well as interactive long and shortwave radiation schemes. A constraint on the integrated turbulent kinetic energy balance ensures that the model remains energetically consistent at all times. The preliminary runs were used to identify the potentially important terms in the heat and moisture budgets of the cloud layer, and to assess the anticipated diurnal variability. These are compared with typical observations from the C130. Sensitivity studies also revealed the remarkable stability of these cloud sheets: a number of negative feedback mechanisms appear to operate to maintain the cloud over an extended time period. These are also discussed. The degree to which such a modelling approach can be used to explain observed features, the specification of boundary conditions and problems of interpretation in non-horizontally uniform conditions is also raised.

  7. Diurnal variation of marine stratocumulus over San Nicolas Island during the FIRE IFO (United States)

    Davies, R.; Blaskovic, M.


    Preliminary analysis was made of data collected at San Nicolas Island during the Intensive Field Observation (IFO) phase of the First International Satellite Cloud Climatology Program's Regional Experiment (FIRE). Of particular interest was an examination of a distinct diurnal variation in the cloud properties, despite an apparent absence of diurnal forcing from the surface. Direct or indirect radiative modulation of such clouds, as proposed by Fravalo at el. (1981) and Turton and Nicholls (1987) indeed seems likely. Preliminary observational evidence for diurnal change in the marine stratocumulus adjacent to San Nicolas Island is presented. A comparison is then made between the observed behavior and predictions from theoretical models of the interactive effect of radiation on boundary layer clouds.

  8. Seasonal variations of Saturn's auroral acceleration region deduced from spectra of auroral radio emissions (United States)

    Kimura, T.; Lamy, L.; Tao, C.; Badman, S. V.; Cecconi, B.; Zarka, P.; Morioka, A.; Miyoshi, Y.; Kasaba, Y.; Maruno, D.; Fujimoto, M.


    Multi-instrumental surveys of Saturn's magnetosphere by Cassini have indicated that auroral radio emissions (Saturnian Kilometric Radiation, SKR), aurorae at UV and IR wavelengths and Energetic Neutral Atoms (ENA) from the inner magnetosphere exhibit periodic behavior at around Saturn's rotational period with the north-south asymmetry and seasonal variations [e.g., Gurnett et al., 2010; Mitchell et al., 2009; Nichols et al., 2010]. These rotationally periodic phenomena are suggestive of distinct magnetosphere-ionosphere coupling current systems, rotating at different periods in the northern and southern hemispheres [e.g., Andrews et al., 2010]. These phenomena suggest that the magnetosphere-ionosphere coupling process and associated energy dissipation process (aurora & SKR) are dynamically dependent on both magnetospheric rotations and long-term conditions of the magnetosphere/ionosphere.

    This work is part of a research project that involves experimental and numeric theoretical activities of calibration and use of a Long Counter detector in the facilities of the IEAv/CTA electron linear accelerator. The version of the detector considered in this work was based on the project of De Pangher and Nichols to determine the intensity of the sources of fast neutrons that will be produced and to serve as secondary caliper of other neutrons detector in a wide range of energy. The objective is to obtain general information on the scattered neutrons in the experimental atmosphere through preliminary theoretical calculations, using the systems of programs MCNP and DOORS, based on Monte Carlo methods and on the discrete ordinates method, respectively. The results are used to visualize the dimensions of the experimental room, where the influence of neutron scattering in the experimental measurements is the possible smallest. (author)

  10. An Investigation of Sound-Symbolism in the Context of Tactile Feeling. (United States)

    Lo, Lap-Yan; Luk, H M; Thompson, Nigel


    Sound symbolism suggests a non-arbitrary relationship between speech sounds and the concepts to which those sounds refer (Hinton, Nichols, & Ohala, 2006 ). Supporting evidence comes primarily from studies investigating how speech sounds relate to semantically compatible visual concepts. The present study therefore attempted to examine sound symbolism in the context of tactile perception. Contrary to the propositions of sound symbolism, participants in Experiment 1 did not consistently assign names with plosive consonant to objects with curved frames. Experiment 2, however, found that names with fricative consonants were more likely to be applied to materials with rough surfaces. The results suggested the existence of a direct relationship between speech sounds and their referent concepts that could be crucial in revealing the phenomenon of sound symbolism. A future study was also proposed to study the contributions of mouth shape and airflow to associations between speech sounds and tactile feelings. (161 words).

    In order to meet tracking performance index of three-axis hydraulic simulator, based on classical quantitative feedback theory (QFT), an improved QFT technique is used to synthesize controller of low gain and bandwidth. By choosing a special nominal plant, the improved method assigns relative magnitude and phase tracking error between system uncertainty and nominal control plant.Relative tracking error induced by system uncertainty is transformed into sensitivity problem and relative tracking error induced by nominal plant forms into a region on Nichols chart. The two constraints further form into a combined bound which is fit for magnitude and phase loop shaping. Because of leaving out pre-filter of classical QFT controller structure, tracking performance is enhanced greatly. Furthermore, a cascaded two-loop control strategy is proposed to heighten control effect. The improved technique's efficacy is validated by simulation and experiment results.

    Full Text Available This paper aims to utilize fuzzy rules and reasoning to determine the controller parameters and the PID controller generates the control signal. The objective of this study is to simulate the proposed scheme on various processes and arrive at results providing better response of the system when compared with best industrial auto-tuning technique: Ziegler-Nichols. The proposed scheme is based upon the Ultimate Gain (Ku and the Period (Tu of the system. The error and rate of change in error gains are tuned manually to get the desired response using LabVIEW. This can also be done with various optimization techniques. A thumb rule for choosing the ranges for Kc, Kd and Ki has been obtained experimentally.

  15. A coupled dynamical-radiational model of stratocumulus (United States)

    Ye, Weizuo


    A model dealing with interactions between the air and low stratiform clouds is presented based on the mixed-layer model Lilly (1968) pioneered and on Deardorff's three dimensional numerical model results. Its main new aspects lie in 1) consideration of the natures of both the atmosphere and cloud; 2) a new entrainment velocity scheme with few arbitrary assumptions; 3) transition from one-mixed layer to two-mixed layer model; and 4) parameterization of radiation and precipitation calculations. The model results for radiation, moisture, and heat turbulent fluxes turn out to be in good agreement with those calculated or observed by Kawa (1988), Nicholls (1984), and Schmets et al. (1981) in California, the North Sea, and the North Atlantic, respectively. Basically, this paper furnishes the theoretical basis for a model to address questions concerning the time-evolution of thermodynamical profiles both in cloud and out of cloud. The applications of this model wil be in a separate paper.

  16. Design and Field Implementation of Auto Tuned Virtual Instrumentation Corrosion Controller (United States)

    Gopalakrishnan, J.; Agnihotri, Ganga; Deshpande, D. M.


    Corrosion in underground metallic pipeline leads to leakage which is hazardous when oil/natural gas is transported. Rate of corrosion in metal pipeline can be controlled by impressing dc current to the gas pipeline and thereby making metal pipeline to act as cathode of corrosion cell. Proportional integral controllers are used in impressed current cathodic protection application; tuning of proportional and integral constants of these controllers requires expertise. Step open, step close and relay tuning methods are compared; relay tuning provided better results for cathodic protection application. Ziegler-Nichols tuning formulas are used to select tuning parameters based on loop response. Virtual instrumentation is used for design, development, testing and field implementation of auto tuned PI controller. Proposed auto tuned proportional integral impressed current cathodic protection controller precisely controls corrosion in pipeline by selecting optimum proportional and integral constants. Controller effectiveness is cross verified using electrical resistance probe.

  17. Engineering, Manufacture and Preliminary Testing of the ITER Toroidal Field (TF) Magnet Helium Cold Circulator (United States)

    Rista, P. E. C.; Shull, J.; Sargent, S.


    The ITER cryodistribution system provides the supercritical Helium (SHe) forced flow cooling to the magnet system using cold circulators. The cold circulators are located in each of five separate auxiliary cold boxes planned for use in the facility. Barber-Nichols Inc. has been awarded a contract from ITER-India for engineering, manufacture and testing of the Toroidal Field (TF) Magnet Helium Cold Circulator. The cold circulator will be extensively tested at Barber-Nichols’ facility prior to delivery for qualification testing at the Japan Atomic Energy Agency's (JAEA) test facility at Naka, Japan. The TF Cold Circulator integrates features and technical requirements which Barber-Nichols has utilized when supplying helium cold circulators worldwide over a period of 35 years. Features include a vacuum-jacketed hermetically sealed design with a very low helium leak rate, a heat shield for use with both nitrogen & helium cold sources, a broad operating range with a guaranteed isentropic efficiency over 70%, and impeller design features for high efficiency. The cold circulator will be designed to meet MTBM of 17,500 hours and MTBF of 36,000 hours. Vibration and speed monitoring are integrated into a compact package on the rotating assembly with operation and health monitoring in a multi-drop PROFIBUS communication environment using an electrical cabinet with critical features and full local and network PLC interface and control. For the testing in Japan and eventual installation in Europe, the cold circulator must be certified to the Japanese High Pressure Gas Safety Act (JHPGSA) and CE marked in compliance with the European Pressure Equipment Directive (PED) including Essential Safety Requirements (ESR). The test methodology utilized at Barber-Nichols’ facility and the resulting test data, validating the high efficiency of the TF Cold Circulator across a broad operating range, are important features of this paper.

    Full Text Available Pathogenic uncultivable treponemes comprise human and animal pathogens including agents of syphilis, yaws, bejel, pinta, and venereal spirochetosis in rabbits and hares. A set of 10 treponemal genome sequences including those of 4 Treponema pallidum ssp. pallidum (TPA strains (Nichols, DAL-1, Mexico A, SS14, 4 T. p. ssp. pertenue (TPE strains (CDC-2, Gauthier, Samoa D, Fribourg-Blanc, 1 T. p. ssp. endemicum (TEN strain (Bosnia A and one strain (Cuniculi A of Treponema paraluisleporidarum ecovar Cuniculus (TPLC were examined with respect to the presence of nucleotide intrastrain heterogeneous sites.The number of identified intrastrain heterogeneous sites in individual genomes ranged between 0 and 7. Altogether, 23 intrastrain heterogeneous sites (in 17 genes were found in 5 out of 10 investigated treponemal genomes including TPA strains Nichols (n = 5, DAL-1 (n = 4, and SS14 (n = 7, TPE strain Samoa D (n = 1, and TEN strain Bosnia A (n = 5. Although only one heterogeneous site was identified among 4 tested TPE strains, 16 such sites were identified among 4 TPA strains. Heterogeneous sites were mostly strain-specific and were identified in four tpr genes (tprC, GI, I, K, in genes involved in bacterial motility and chemotaxis (fliI, cheC-fliY, in genes involved in cell structure (murC, translation (prfA, general and DNA metabolism (putative SAM dependent methyltransferase, topA, and in seven hypothetical genes.Heterogeneous sites likely represent both the selection of adaptive changes during infection of the host as well as an ongoing diversifying evolutionary process.

  19. Structure and dynamics of cholic acid and dodecylphosphocholine-cholic acid aggregates. (United States)

    Sayyed-Ahmad, Abdallah; Lichtenberger, Lenard M; Gorfe, Alemayehu A


    Bile acids are powerful detergents that emulsify and solubilize lipids, vitamins, cholesterol and other molecules in the biliary tract and intestines. It has long been known that bile acids form soluble mixed micelles with lipids. However, the detailed thermodynamic and structural properties of these micelles are not fully understood. This study sheds light on this issue based on results from multiple molecular dynamics simulations of cholic acid (CA) and dodecylphosphocholine (DPC) mixed micelles. We found that CA molecules form aggregates of up to 12 monomers with a mean size of 5-6. In agreement with several previous simulations and earlier predictions, the overall shape of these CA clusters is oblate disk-like such that the methyl groups point toward the core of the aggregate and the hydroxyl groups point away from it. The self-aggregation behavior of the CA clusters in the DPC-CA mixture is similar to the pure CA. Furthermore, the sizes and aggregation numbers of the DPC-CA mixed micelles are linearly dependent on CA molarity. In agreement with the radial shell model of Nichols and Ozarowski [Nichols, J. W.; Ozarowski, J. Biochemistry 1990, 29, 4600], our results demonstrate that CA molecules form a wedge between the DPC molecules with their hydroxyl and carboxyl groups facing the aqueous phase while their methyl groups are buried in and face the hydrocarbon core of the DPC micelle. The DPC-CA micelles simulated here tend to be spherical to prolate in shape, with the deviation from spherical geometry significantly increasing with increasing CA:DPC ratio.

    Lai, Chun-Ze; Koseoglu, Secil S; Lugert, Elizabeth C; Boswell, Paul G; Rábai, József; Lodge, Timothy P; Bühlmann, Philippe


    Fluorous media are the least polar and polarizable condensed phases known. Their use as membrane materials considerably increases the selectivity and robustness of ion-selective electrodes (ISEs). In this research, a fluorous amorphous perfluoropolymer was used for the first time as a matrix for an ISE membrane. Electrodes for pH measurements with membranes composed of poly[4,5-difluoro-2,2-bis(trifluoromethyl)-1,3-dioxole]-co-poly(tetrafluoroethylene) (87% dioxole monomer content; known as Teflon AF2400) as polymer matrix, a linear perfluorooligoether as plasticizer, sodium tetrakis[3,5-bis(perfluorohexyl)phenyl]borate providing for ionic sites, and bis[(perfluorooctyl)propyl]-2,2,2-trifluoroethylamine as H+ ionophore were investigated. All electrodes had excellent potentiometric selectivities, showed Nernstian responses to H+ over a wide pH range, exhibited enhanced mechanical stability, and maintained their selectivity over at least 4 weeks. For membranes of low ionophore concentration, the polymer affected the sensor selectivity noticeably at polymer concentrations exceeding 15%. Also, the membrane resistance increased quite strongly at high polymer concentrations, which cannot be explained by the Mackie-Meares obstruction model. The selectivities and resistances depend on the polymer concentration because of a functional group associated with Teflon AF2400, with a concentration of one functional group per 854 monomer units of the polymer. In the fluorous environment of these membranes, this functional group binds to Na+, K+, Ca2+, and the unprotonated ionophore with binding constants of 10(3.5), 10(1.8), 10(6.8), and 10(4.4) M(-1), respectively. Potentiometric and spectroscopic evidence indicates that these functional groups are COOH groups formed by the hydrolysis of carboxylic acid fluoride (COF) groups originally present in Teflon AF2400. The use of higher ionophore concentrations removes the undesirable effect of these COOH groups almost completely

  1. Endocannabinoids and pain: spinal and peripheral analgesia in inflammation and neuropathy. (United States)

    Rice, A S C; Farquhar-Smith, W P; Nagy, I


    , endogenous and exogenous, in analgesia have been recently reviewed elsewhere (Rice, Curr Opi Invest Drugs 2001; 2: 399-414; Pertwee, Prog Neurobil 2001; 63: 569-611; Rice, Mackie, In: Evers A. S, ed. Anesthetic Pharmacology: Physiologic Principles and Clinical Practice. St. Louis: Harcourt Health Sciences, 2002). Since a major goal in the development of cannabinoid-based analgesics is to divorce the antinociceptive effects from the psychotrophic effects, the discussion will focus on the antinociceptive effects produced at the spinal cord and/or peripheral level as these areas are the most attractive targets in this regard. A mechanistic discussion of the "framework" for analgesia will be followed by a description of studies examining the role of endocannabinoids in relieving pain; since the elucidation of these effects was undertaken using synthetic cannabinoids, reference will also be made to such studies, in the context of endocannabinoids.

    Purpose: The aim of this work is the application of the formalism for ionization chamber reference dosimetry of small and nonstandard fields [R. Alfonso, P. Andreo, R. Capote, M. S. Huq, W. Kilby, P. Kjaell, T. R. Mackie, H. Palmans, K. Rosser, J. Seuntjens, W. Ullrich, and S. Vatnitsky, 'A new formalism for reference dosimetry of small and nonstandard fields,' Med. Phys. 35, 5179-5186 (2008)] to the CyberKnife robotic radiosurgery system. Correction factors for intermediate calibration fields, a machine-specific reference field (msr) and two plan-class specific reference fields (pcsr), have been studied. Furthermore, the applicability of the new formalism to clinical dosimetry has been analyzed through the investigation of two clinical treatments. Methods: PTW31014 and Scanditronix-Wellhofer CC13 ionization chamber measurements were performed for the fields under investigation. Absorbed dose to water was determined using alanine reference dosimetry, and experimental correction factors were calculated from alanine to ionization chamber readings ratios. In addition, correction factors were calculated for the intermediate calibration fields and one of the clinical treatment fields using the Monte Carlo method and these were compared with the experimental values. Results: Overall correction factors deviating from unity by approximately 2% were obtained from both measurements and simulations, with values below and above unity for the studied intermediate calibration fields and clinical fields for the ionization chambers under consideration. Monte Carlo simulations yielded correction factors comparable with those obtained from measurements for the machine-specific reference field, although differences from 1% to 3.3% were observed between measured and calculated correction factors for the composite intermediate calibration fields. Dose distribution inhomogeneities are thought to be responsible for such discrepancies. Conclusions: The differences found between

    Specialized radiation treatment such as SRS/SRT. SBRT, IMRT, VMAT, Tomotherapy, CyberKnife and Gamma Knife use small fields or combination of small fields where dosimetry is challenging and uncertain due to non-equilibrium conditions such as longitudinal and lateral disequilibrium. Additionally the primary photon fluence is greatly affected by the obstruction of the source size by the jaws creating a large dose gradient across the field. Electronic equilibrium is a phenomenon associated with the range of secondary particles which depend on the beam energy, photon spectrum and the composition of the medium. Additionally, the finite size of detectors creates volume averaging and fluence perturbations especially in small fields. The IAEA/AAPM has provided a frame work for non-compliant reference dosimetry in small fields1. The AAPM TG-1552 has adopted this frame work to provide guidelines in relative dosimetry. This course provides the insight of TG-155 that defines small field, provides recommendations for suitable detectors and associated correction factors to convert reading to dose. Recommendations of a good working practice for relative dosimetry measurements (PDD, TMR, output factor, etc.) and dose calculations based on the new formulation is are elaborated. It also discusses beam modeling and dose calculations as a critical step in clinical utilization of small field radiotherapy. Small errors in beam data, approximations in dose algorithms, or misaligned of detectors and field settings can propagate into large errors in planned and delivered dose. The modeling and treatment planning aspects of small field dosimetry are reviewed with emphasis on the most critical parts for ensuring accurate and safe radiation therapy. Discussion on k(fmsr, fclin) for commercially available detectors are also provided.1 P. Alfonso, P. Andreo, R. Capote, M. S. Huq, W. Kilby, P. Kjall, T. R. Mackie, H. Palmans, K. Rosser, J.

  5. Histological analysis of spermatogenesis and the germ cell development strategy within the testis of the male Western Cottonmouth Snake, Agkistrodon piscivorus leucostoma. (United States)

    Gribbins, Kevin M; Rheubert, Justin L; Collier, Matthew H; Siegel, Dustin S; Sever, David M


    Cottonmouth (Agkistrodon piscivorus leucostoma) testes were examined histologically to determine the germ cell development strategy employed during spermatogenesis. Testicular tissues from Cottonmouths were collected monthly from swamps around Hammond, Louisiana. Pieces of testis were fixed in Trump's fixative, dehydrated in ethanol, embedded in Spurr's plastic, sectioned with an ultramicrotome, and stained with toluidine blue and basic fuchsin. Spermatogenesis within Cottonmouths occurs in two independent events within a single calendar year. The testes are active during the months of March-June and August-October with spermiation most heavily observed during April-May and October. To our knowledge, this is the first study that describes bimodal spermatogenesis occurring in the same year within the subfamily Crotalinae. During spermatogenesis, no consistent spatial relationships are observed between germ cell generations. Typically, either certain cell types were missing (spermatocytes) or the layering of 3-5 spermatids and/or spermatocytes within the same cross-section of seminiferous tubule prevented consistent spatial stages from occurring. This temporal pattern of sperm development is different from the spatial development found within birds and mammals, being more reminiscent of that seen in amphibians, and has now been documented within every major clade of reptile (Chelonia, Serpentes, Sauria, Crocodylia). This primitive-like sperm development, within a testis structurally similar to mammals and birds, may represent an intermediate testicular model within the basally positioned (phylogenetically) reptiles that may be evolutionarily significant.

    Blake, Diane A.


    Progress Report Date: 01/23/06 (report delayed due to Hurricane Katrina) Report of results to date: The goals of this 3-year project are to: (1) update and successfully deploy our present immunosensors at DOE sites; (2) devise immunosensor-based assays for Pb(II), Hg(II), chelators, and/or Cr(III) in surface and groundwater; and (3) develop new technologies in antibody engineering that will enhance this immunosensor program. Note: Work on this project was temporarily disrupted when Hurricane Katrina shut down the University on August 29, 2005. While most of the reagents stored in our refrigerators and freezers were destroyed, all of our hybridoma cell lines were saved because they had been stored in liquid nitrogen. We set up new tissue culture reactors with the hybridomas that synthesize the anti-uranium antibodies, and are purifying new monoclonal antibodies from these culture supernatants. Both the in-line and the field-portable sensor were rescued from our labs in New Orleans in early October, and we continued experiments with these sensors in the temporary laboratory we set up in Hammond, LA at Southeastern Louisiana University.

    The kinetics and equilibrium of the hydride transfer reaction between lumiflavin and a number of substituted quinones was studied using density functional theory. The impact of electron withdrawing/donating substituents on the redox potentials of quinones was studied. In addition, the role of these substituents on the kinetics of the hydride transfer reaction with lumiflavin was investigated in detail under the transition state (TS) theory assumption. The hydride transfer reactions were found to be more favorable for an electron-withdrawing substituent. The activation barrier exhibited a quadratic relationship with the driving force of these reactions as derived under the formalism of modified Marcus theory. The present study found a significant extent of electron delocalization in the TS that is stabilized by enhanced electrostatic, polarization, and exchange interactions. Analysis of geometry, bond-orders, and energetics revealed a predominant parallel (Leffler-Hammond) effect on the TS. Closer scrutiny reveals that electron-withdrawing substituents, although located on the acceptor ring, reduce the N-H bond order of the donor fragment in the precursor complex. Carried out in the gas-phase, this is the first ever report of a theoretical study of flavin's hydride transfer reactions with quinones, providing an unfiltered view of the electronic effect on the nuclear reorganization of donor-acceptor complexes.

  8. Accumulation rates of airborne heavy metals in wetlands (United States)

    Souch, C.J.; Filippelli, G.M.; Dollar, N.; Perkins, S.; Mastalerz, Maria


    Accumulation rates of heavy metals (Cd, Cr, Cu, Mn, Pb, and Zn) retained in wetland sediments in northwest Indiana-downwind of the Chicago-Gary-Hammond industrial area-are quantified to assess anthropogenic influences on atmospheric fluxes. Metal concentrations for 22 sediment cores are determined by ICP-AES after ashing and strong acid extraction. Relations between organic content and metal concentrations at depth are used to separate natural and anthropogenic sources. Accumulation rates over the lifetime of the wetlands (???4500 years) have averaged 0.2 (Cd), 1.4 (Cu), 1.7 (Cr), 13.4 (Mn), 4.8 (Pb), and 18.7 (Zn) mg m-2 y-1. Rates for the last 100 years have increased on average by factors of 6 (Cd), 8 (Cu), 10 (Mn), 15 (Pb), and 30 (Zn), remaining effectively constant for Cr. Where the wetlands have been drained, metals have been lost from the sediments, owing to changes in organic content and local hydrochemistry (exposure to acidic rainfall). Sediment-based accumulation rates at the undrained sites are higher, though generally consistent, with measured and modeled atmospheric fluxes documented by short-term studies conducted over the last three decades. The fraction of the total metals in the wetlands estimated to be of anthropogenic origin ranges from approximately 3% for Cr, up to approximately 35% for Pb, and 70% for Zn. This historic legacy of contamination must be considered in land management decisions, particularly when wetlands are drained.

    BP Products North America Inc. (BP) owns and operates a petroleum refinery located on approximately 1,700 acres in Whiting, East Chicago, and Hammond, Indiana, near the southern tip of Lake Michigan. BP provided funding to Purdue University-Calumet Water Institute (Purdue) and Argonne National Laboratory (Argonne) to conduct studies related to wastewater treatment and discharges. Purdue and Argonne are working jointly to identify and characterize technologies that BP could use to meet the previous discharge permit limits for total suspended solids (TSS) and ammonia after refinery modernization. In addition to the technology characterization work, Argonne conducted a separate project task, which is the subject of this report. In Phase I of a two-part study, Argonne estimated the current levels of discharge to southern Lake Michigan from significant point and nonpoint sources in Illinois, Indiana, and portions of Michigan. The study does not consider all of the chemicals that are discharged. Rather, it is narrowly focused on a selected group of pollutants, referred to as the 'target pollutants'. These include: TSS, ammonia, total and hexavalent chromium, mercury, vanadium, and selenium. In Phase II of the study, Argonne will expand the analysis to cover the entire Lake Michigan drainage basin.

    Zodinpuia Pachuau; Kiew S Kharnaior; R H Duncan Lyngdoh


    This ab initio study examines two pathways (one concerted and the other two-step) for isomerization of the linear propargyl cation to the aromatic cyclopropenyl cation, also probing the phenomenon of solvation of this reaction by simple lone pair donors (NH3, H2O, H2S and HF) which bind to the substrate at two sites. Fully optimized geometries at the B3LYP/6-31G(d) level were used, along with single point QCISD(T)/6-311+G(d,p) and accurate G3 level calculations upon the DFT optimized geometries. For the unsolvated reaction, the two-step second pathway is energetically favoured over the one-step first pathway. Lone pair donor affinity for the various C3H$^{+}_{3}$ species follows the uniform order NH3 > H2S>H2O>HF. The activation barriers for the solvated isomerizations decrease in the order HF>H2O>H2S>NH3 for both pathways. The number of lone pairs on the donor heteroatom as well as the heteroatom electronegativity are factors related to both these trends. Compared to the unsolvated cases, the solvated reactions have transition states which are usually ‘later’ in position along the reaction coordinate, validating the Hammond postulate.

    Full Text Available Beth A Scholz, Cara L Hammonds, Chad S BoomershineDepartment of Medicine, Vanderbilt University, Nashville, TN, USAAbstract: Fibromyalgia syndrome (FMS is a widespread pain condition associated with a wide range of additional symptoms including fatigue, insomnia, depression, anxiety and stiffness. Duloxetine is one of three medications currently FDA approved for use in FMS management. Duloxetine is a mixed serotonin and norepinephrine reuptake inhibitor (SNRI that functions by increasing central nervous system levels of serotonin and norepinephrine. This review is a primer on use of duloxetine in FMS management and includes information on pharmacology and pharmacokinetics, a review of the three duloxetine FMS treatment trials currently in publication, a discussion of the safety and tolerability of duloxetine, and patient-focused perspectives on duloxetine use in FMS management. Duloxetine has proven efficacy in managing pain and mood symptoms in adult FMS patients with and without major depressive disorder. However, due to side effects, duloxetine must be used with caution in patients with fatigue, insomnia, gastrointestinal complaints, headache, cardiovascular disease, bleeding-risk, and in those 24 years of age and younger due to risk of suicidality. Duloxetine use should be avoided in patients with liver disease or alcoholics. As with all medications, duloxetine is best used as part of an individualized regimen that includes nonpharmacologic modalities of exercise, education and behavioral therapies.Keywords: fibromyalgia, duloxetine, SNRI, safety

  13. Theoretical study of the oxidation mechanisms of naphthalene initiated by hydroxyl radicals: the H abstraction pathway. (United States)

    Shiroudi, Abolfazl; Deleuze, Michael S


    Reaction mechanisms for the initial stages of naphthalene oxidation at high temperatures (T ≥ 600 K) have been studied theoretically using density functional theory along with various exchange-correlation functionals, as well as the benchmark CBS-QB3 quantum chemical approach. These stages correspond to the removal of hydrogen atoms by hydroxyl radical and the formation thereby of 1- and 2-naphthyl radicals. Bimolecular kinetic rate constants were estimated by means of transition state theory. The excellent agreement with the available experimental kinetic rate constants demonstrates that a two-step reaction scheme prevails. Comparison with results obtained with density functional theory in conjunction with various exchange-correlation functionals also shows that DFT remains unsuited for quantitative insights into kinetic rate constants. Analysis of the computed structures, bond orders, and free energy profiles demonstrates that the reaction steps involved in the removal of hydrogen atoms by OH radicals satisfy Hammond's principle. Computations of branching ratios also show that these reactions do not exhibit a particularly pronounced site-selectivity.

  14. Uncatalyzed thermal gas phase aziridination of alkenes by organic azides. Part I: Mechanisms with discrete nitrene species

    Indian Academy of Sciences (India)



    Alkene aziridination by azides through uncatalyzed thermal gas phase routes has been studiedusing the DFT B3LYP/6-31G(d,p) method, where the possible role of discrete nitrene intermediates is emphasized.The thermal decomposition of azides is studied using the MP2/aug-cc-pVDZ strategy as well. The MP2(but not the B3LYP) results discount the existence of singlet alkylnitrenes where the alkyl group has an α-hydrogen. Addition of the lowest lying singlet and triplet nitrenes R-N (R = H, Me, Ac) to four different alkenesubstrates leading to aziridine formation was studied by the B3LYP method. Singlet nitrenes with alkenes canyield aziridines via a concerted mechanism, where H-N insertion takes place without a barrier, whereas Me-Nshows larger barriers than Ac-N. Methyl substitution in the alkene favors this reaction. Triplet nitrene additionto alkenes is studied as a two-step process, where the initially formed diradical intermediates cyclize to formaziridines by ISC (intersystem crossing) and collapse. Scope for C-C bond rotation in the diradical leads to lossof stereochemical integrity for triplet nitrene addition to cis- and trans-2-butenes. Geometries of the transitionstates in the various reaction steps studied here are described as “early” or “late” in good accordance with theHammond postulate.

  16. Medical education and cognitive continuum theory: an alternative perspective on medical problem solving and clinical reasoning. (United States)

    Custers, Eugène J F M


    Recently, human reasoning, problem solving, and decision making have been viewed as products of two separate systems: "System 1," the unconscious, intuitive, or nonanalytic system, and "System 2," the conscious, analytic, or reflective system. This view has penetrated the medical education literature, yet the idea of two independent dichotomous cognitive systems is not entirely without problems.This article outlines the difficulties of this "two-system view" and presents an alternative, developed by K.R. Hammond and colleagues, called cognitive continuum theory (CCT). CCT is featured by three key assumptions. First, human reasoning, problem solving, and decision making can be arranged on a cognitive continuum, with pure intuition at one end, pure analysis at the other, and a large middle ground called "quasirationality." Second, the nature and requirements of the cognitive task, as perceived by the person performing the task, determine to a large extent whether a task will be approached more intuitively or more analytically. Third, for optimal task performance, this approach needs to match the cognitive properties and requirements of the task. Finally, the author makes a case that CCT is better able than a two-system view to describe medical problem solving and clinical reasoning and that it provides clear clues for how to organize training in clinical reasoning.

  17. Voluntary approaches to solid waste management in small towns: a case study of community involvement in household hazardous waste recycling. (United States)

    Massawe, Ephraim; Legleu, Tye; Vasut, Laura; Brandon, Kelly; Shelden, Greg


    An enormous amount of household hazardous waste (HHW) is generated as part of municipal solid waste. This scenario presents problems during disposal, including endangering human health and the environment if improperly disposed. This article examines current HHW recycling efforts in Hammond, Louisiana, with the following objectives: (a) analyze factors and attitudes that motivate residents to participate in the program; (b) quantify various types of HHW; and (c) analyze the e-waste stream in the HHW. Residents and city officials who were surveyed and interviewed cited that commitment shown by local authorities and passion to protect the environment and human health were part of their active participation in the program. An awareness program has played a key role in the success of the program. A legislation specific to e-waste is encouraged. While knowledge and information on laws and permit application processes and the promotion of greener products are encouraged, provision of storage or collection facilities and communal transportation will further motivate more residents to participate in the recycling program.

  18. The Gore-Tex Suture in Periareolar Closure: A Modified Closure Technique. (United States)

    Chapman, Jade; Ingram, Scott


    In breast reduction and mastopexy procedures, the periareolar closure forms a vital component of the surgery. Periareolar closures completed with an absorbable suture may be prone to significant widening, hypertrophy and/or areolar distortion. In an effort to avoid this, some surgeons use a non-absorbable/permanent suture material [Franco (Arch Plast Surg 41 (6): 728-733, 2014)]. Hammond (Plast Reconstr Surg 119 (3):804-809, 2007) recommends the use of a Gore-Tex® suture for this purpose in view of the supple, pliable nature of the material; however, there remain at least occasional instances of infection and extrusion of the knot used to tie off the Gore-Tex "purse-string" [Franco (Arch Plast Surg 41 (6): 728-733, 2014); Salgarello (Aesthet Plast Surg 37 (5):1061-1062, 2013)]. We describe a method of securing the suture ends, which avoids the creation of a bulky knot, thus minimising the risk of infection and suture extrusion.

  19. A Common Origin for Ridge-and-Trough Terrain on Icy Satellites by Sluggish Lid Convection

    CERN Document Server

    Barr, Amy C


    Ridge and trough terrain is a common landform on icy satellites of the outer solar system. Examples include the grooved terrain on Ganymede, gray bands on Europa, coronae on Uranus's moon Miranda, and ridges and troughs in the northern plains of Saturn's small, but active, moon Enceladus. Regardless of setting, the heat flow and strain rates associated with the formation of each of these terrains are similar: heat flows of order tens to a hundred milliwatts per meter squared, and deformation rates of order $10^{-16}$ to $10^{-12}$ s$^{-1}$. Barr (2008) and Hammond & Barr (2014a) have previously shown that the conditions associated with the formation of ridge and trough terrain on Ganymede and the south polar terrain on Enceladus are consistent with solid-state ice shell convection in a shell with a weak surface. Here, we show that sluggish lid convection can simultaneously create the heat flow and deformation appropriate for the formation of ridge and trough terrains on a number of satellites. This conclu...

  20. Innovative Clean Coal Technology (ICCT): 500 MW demonstration of advanced wall-fired combustion techniques for the reduction of nitrogen oxide (NO{sub x}) emissions from coal-fired boilers. Technical progress report, First quarter 1992

    Energy Technology Data Exchange (ETDEWEB)


    This quarterly report discusses the technical progress of an Innovative Clean Coal Technology (ICCT) demonstration of advanced wall-fired combustion techniques for the reduction of nitrogen oxide (NO{sub x}) emissions from coal-fired boilers. The project is being conducted at Georgia Power Company`s Plant Hammond Unit 4 located near Rome, Georgia. The primary goal of this project is the characterization of the low NO{sub x} combustion equipment through the collection and analysis of long-term emissions data. A target of achieving fifty percent NO{sub x} reduction using combustion modifications has been established for the project. The project provides a stepwise retrofit of an advanced overfire air (AOFA) system followed by low NO{sub x} burners (LNB). During each test phase of the project, diagnostic, performance, long-term, and verification testing will be performed. These tests are used to quantify the NO{sub x} reductions of each technology and evaluate the effects of those reductions on other combustion parameters such as particulate characteristics and boiler efficiency.

    A large protein was purified from bovine kidney, using selective extraction with EDTA to solubilize proteins anchored by divalent cation-dependent interactions. An antiserum raised against the purified protein labeled the apical cell surface of the epithelial cells in proximal tubules and the luminal surface of small intestine. Ten peptide sequences, derived from the protein, all matched the recently published sequences for rat (Moestrup, S. K., Kozyraki, R., Kristiansen, M., Kaysen, J. H., Holm Rasmussen, H., Brault, D., Pontillon, F., Goda, F. O., Christensen, E. I., Hammond, T. G., and Verroust, P. J. (1998) J. Biol. Chem. 273, 5235-5242) and human cubilin, a receptor for intrinsic factor-vitamin B12 complexes, identifying the protein as bovine cubilin. In electron microscopy, a three-armed structure was seen, indicating an oligomerization of three identical subunits. This model was supported by the Mr values of about 1,500,000 for the intact protein and 440,000 for its subunits obtained by analytical ultracentrifugation. In a search for a potential assembly domain, we identified a region of heptad repeats in the N-terminal part of the cubilin sequence. Computer-assisted analysis supported the presence of a coiled-coil alpha-helix between amino acids 103 and 132 of the human cubilin sequence and predicted the formation of a triple coiled-coil. We therefore conclude that cubilin forms a noncovalent trimer of identical subunits connected by an N-terminal coiled-coil alpha-helix.

  3. Problems in separating species with similar habits and vocalizations (United States)

    Robbins, C.S.; Stallcup, R.W.; Ralph, C. John; Scott, J. Michael


    The possibilities for species misidentification based on vocalization or habitat association are high. However, the magnitude of the errors actually perpetrated is generally within an acceptable range in most types of bird survey work. Examples of problems discussed are: congeners that are similar in appearance or in song (such as Chimney and Vaux's Swifts, Chaetura pelagica, C. vauxi; Hammond's, Dusky and Gray Flycatchers, Empidonax hammondii, E. oberholseri, E. wrightii; Willow and Alder Flycatchers, E. traillii, E. alnorum; Common and Fish Crows, Corvus brachyrhynchos, C. ossifragus); birds that are misidentified because they are not expected by the observer (House Finches, Carpodacus mexicanus, invading new areas of eastern U.S.); birds that imitate other species (especially Starling, Sturnus vulgaris, and Mockingbird, Mimus polyglottos); birds in mixed flocks; birds with geographic differences in vocalizations (Solitary Vireo, Vireo solitarius); woodpeckers that are only heard drumming; and nests or eggs that are misidentified. Equally serious problems are the errors resulting from undetected species and from careless recording or failure to check manuscripts against original data. The quality of published count work can be improved considerably by (1) recognizing the problems that exist, (2) standardizing techniques for dealing with situations where not all birds can be identified, and (3) routinely applying all appropriate safeguards such as verification by mist netting and measuring, photography, tape recording or playback, additional observations, and careful verification of all entries in the final manuscript.

  4. Sensitization and quenching in the conversion of light energy into chemical energy. Progress report, February 1, 1979-January 31, 1980. [Benzylic chlorides

    Energy Technology Data Exchange (ETDEWEB)

    Cristol, S.J.


    Data have been accumulated on the rates of excitation transfer from acetone or acetophenone sensitizers to several benzylic chlorides in acetonitrile-t-butyl alcohol or acetone-t-butyl alcohol and on the lifetimes of the excited triplet intermediates leading to solvolysis products (arylmethyl t-butyl ethers and arylmethanols). Lifetimes were found to be in the 0-2 nsec range. In direct irradiation, in t-butyl alcohol or acetonitrile-t-butyl alcohol, t-butyl ethers are formed from intermediates which are either singlets or are triplets of short lifetimes (0-2 nsec). Long-lived triplets, which do not lead to t-butyl ethers or to other products, but which decay to starting materials, and which arise by intersystem crossing from excited singlet states, were discovered by their ability to isomerize cis-piperylene (Hammond-Lamola quenching). These hidden triplets were shown to be produced as well by excitation transfer from benzophenone. They represent a large fraction of the energy wastage in this system. Work has begun on the preparation of materials for study of optically active benzylic chloride solvolyses, for study of optically active benzylic chloride solvolyses, for study of intramolecular (2 + 2) cycloadditions and for di-..pi..-methane studies, in our attempts to understand the mechanistic details of these important photochemical reactions.

    Cristol, S.J.


    Extensive data from Stern-Volmer, Lamola-Hammond, and Ilenda-Daughenbaugh-Cristol quenching kinetics have now been accumulated on photosolvolysis in t-butyl alcohol for benzyl chloride and a number of meta and para substituted benzyl chlorides. Evidence for the existence of two triplet states, one relatively short-lived (tau 0-2 nsec) which gives solvolysis product and a second, relatively long-lived (tau 5-26 nsec), which does not give product, but instead is energy wasting, has been accumulated. The system, p-acetobenzyl chloride, has been investigated in detail. A method for quenching of singlet states for measurement of singlet lifetimes in the 100 picosecond to nanosecond range is being developed. Preliminary work on benzyl acetate photosolvolysis has been conducted. Some work on the goemetrical requirements for intra-molecular excitation transfer in bichromophoric molecules has been conducted. Several dienes related to norbornadiene have been prepared and preparative photoisomerizations to quadricyclene analogues have been carried out. Considerable attention has been given to certain di-..pi..-methane rearrangements, work on most of which is still in progress. One system, the ethyl ester of dibenzobarrelene-7-carboxylic acid, has been scrutinized in detail.

    Full Text Available This is an exploratory case study aimed at investigating whether or not International English Language Testing Systems (IELTS scores correspond with literacy levels. During the 2011-2012 academic year, 20 first semester students in the English Literature Program in the Faculty of Language and Cultural Studies (Fakultas Bahasa dan Ilmu Budaya at Universitas Stikubank (UNISBANK were randomly selected to take the IELTS. Results were matched against predetermined criteria for literacy levels (Hammond, et al. 1992 in order to classify them into the appropriate levels of literacy. Findings indicate that all students (100 percent were at the performative level of literacy with respect to their overall IELTS scores. Only 25 percent of the students on the speaking subtest and 20 percent of the students on the reading subtest managed to test at the functional level. It is therefore recommended that action research be conducted in Central Java level to upgrade the level of literacy from the performative level up to the informative level. As well, similar research may be conducted with a multi-disciplinary approach employing a correlational study between IELTS band scores with literacy levels.

    A high flame temperature oxy-combustion test facility consisting of a 5 MWe equivalent test boiler facility and 20 KWe equivalent IPR® was constructed at the Hammond, Indiana manufacturing site. The test facility was operated natural gas and coal fuels and parametric studies were performed to determine the optimal performance conditions and generated the necessary technical data required to demonstrate the technologies are viable for technical and economic scale-up. Flame temperatures between 4930-6120F were achieved with high flame temperature oxy-natural gas combustion depending on whether additional recirculated flue gases are added to balance the heat transfer. For high flame temperature oxy-coal combustion, flame temperatures in excess of 4500F were achieved and demonstrated to be consistent with computational fluid dynamic modeling of the burner system. The project demonstrated feasibility and effectiveness of the Jupiter Oxygen high flame temperature oxy-combustion process with Integrated Pollutant Removal process for CCS and CCUS. With these technologies total parasitic power requirements for both oxygen production and carbon capture currently are in the range of 20% of the gross power output. The Jupiter Oxygen high flame temperature oxy-combustion process has been demonstrated at a Technology Readiness Level of 6 and is ready for commencement of a demonstration project.

  8. Calculating hominin and nonhuman anthropoid femoral head diameter from acetabular size. (United States)

    Plavcan, J Michael; Hammond, Ashley S; Ward, Carol V


    Femoral head size provides important information on body size in extinct species. Although it is well-known that femoral head size is correlated with acetabular size, the precision with which femoral head size can be estimated from acetabular size has not been quantified. The availability of accurate 3D surface models of fossil acetabular remains opens the possibility of obtaining accurate estimates of femoral head size from even fragmentary fossil remains [Hammond et al.,: Am J Phys Anthropol 150 (2013) 565-578]. Here we evaluate the relationship between spheres fit to surface models of the femoral head and acetabulum of a large sample of extant anthropoid primates. Sphere diameters are tightly correlated and scale isometrically. In spite of significant taxonomic and possibly functional differences in the relationship between femoral head size and acetabulum size, percent prediction errors of estimated femoral head size remain low regardless of the taxonomic composition of the reference sample. We provide estimates of femoral head size for a series of fossil hominins and monkeys. © 2014 Wiley Periodicals, Inc.

  9. Explicit entrainment parameterization in the general circulation model ECHAM5-HAM (United States)

    Siegenthaler-Le Drian, Colombe; Spichtinger, Peter; Lohmann, Ulrike


    The complex interactions affecting cloud lifetime and liquid water path (LWP) are not well captured in state-of-the-art general circulation models (GCM). A recent climate model intercomparison showed an overestimation of the positive correlation of LWP with aerosol optical depth by a factor of two as compared to MODIS data for almost all participating models (Quaas et al., 2009). As the authors suggest, a proper interaction of the boundary layer dynamics, particularly the inclusion of cloud top entrainment may lead to an improvement. ECHAM5 was one of the participating model. In this model, the turbulent fluxes in the planetary boundary layer are simulated using a turbulent kinetic energy - mixing length scheme. It has been showed that its performance diminishes when the resolution decreases, the different fluxes being not represented satisfactory with 31 vertical levels, particularly at the cloud top (Lenderink et al., 2000). We thus replace the turbulent fluxes by the explicit entrainment closure by Turton and Nicholls (1987) at the top of the stratocumulus capped boundary layers. The turbulent fluxes are weighted with the cloud cover to apply the entrainment closure only above clouds. In addition, we use an explicit term for the radiative cooling contribution in the buoyancy production term. We use the new version of the Hamburg general circulation model ECHAM5-HAM (Roeckner et al., 2003; Stier et al., 2005). The cloud scheme that is used for this study includes the double-moment cloud microphysics scheme for cloud droplets and ice crystals (Lohmann et al., 2007). The principal effect of the explicit entrainment is to dry and warm the planetary boundary layer. The averaged profiles are more stable and the inversion is reduced. The stratocumulus deck is reduced in all typical stratocumulus regions. In a single column version of the model, the diurnal cycle simulated in cloud cover or equivalentely in cloud water is much more representative of observed subtropical

  10. Coastal vulnerability: climate change and natural hazards perspectives (United States)

    Romieu, E.; Vinchon, C.


    Introduction Studying coastal zones as a territorial concept (Integrated coastal zone management) is an essential issue for managers, as they have to consider many different topics (natural hazards, resources management, tourism, climate change…). The recent approach in terms of "coastal vulnerability" studies (since the 90's) is the main tool used nowadays to help them in evaluating impacts of natural hazards on coastal zones, specially considering climate change. This present communication aims to highlight the difficulties in integrating this concept in risk analysis as it is usually practiced in natural hazards sciences. 1) Coastal vulnerability as a recent issue The concept of coastal vulnerability mainly appears in the International panel on climate change works of 1992 (IPCC. 2001), where it is presented as essential for climate change adaptation. The concept has been defined by a common methodology which proposes the assessment of seven indicators, in regards to a sea level rise of 1m in 2100: people affected, people at risk, capital value at loss, land at loss, wetland at loss, potential adaptation costs, people at risk assuming this adaptation. Many national assessments have been implemented (Nicholls, et al. 1995) and a global assessment was proposed for three indicators (Nicholls, et al. 1999). The DINAS-Coast project reuses this methodology to produce the DIVA-tool for coastal managers (Vafeidis, et al. 2004). Besides, many other methodologies for national or regional coastal vulnerability assessments have been developed (review by (UNFCCC. 2008). The use of aggregated vulnerability indicators (including geomorphology, hydrodynamics, climate change…) is widespread: the USGS coastal vulnerability index is used worldwide and was completed by a social vulnerability index (Boruff, et al. 2005). Those index-based methods propose a vulnerability mapping which visualise indicators of erosion, submersion and/or socio economic sensibility in coastal zones

  11. Exploring extensions to multi-state models with multiple unobservable states (United States)

    Bailey, L.L.; Kendall, W.L.; Church, D.R.; Thomson, David L.; Cooch, Evan G.; Conroy, Michael J.


    Many biological systems include a portion of the target population that is unobservable during certain life history stages. Transition to and from an unobservable state may be of primary interest in many ecological studies and such movements are easily incorporated into multi-state models. Several authors have investigated properties of open-population multi-state mark-recapture models with unobservable states, and determined the scope and constraints under which parameters are identifiable (or, conversely, are redundant), but only in the context of a single observable and a single unobservable state (Schmidt et al. 2002; Kendall and Nichols 2002; Schaub et al. 2004; Kendall 2004). Some of these constraints can be relaxed if data are collected under a version of the robust design (Kendall and Bjorkland 2001; Kendall and Nichols 2002; Kendall 2004; Bailey et al. 2004), which entails >1 capture period per primary period of interest (e.g., 2 sampling periods within a breeding season). The critical assumption shared by all versions of the robust design is that the state of the individual (e.g. observable or unobservable) remains static for the duration of the primary period (Kendall 2004). In this paper, we extend previous work by relaxing this assumption to allow movement among observable states within primary periods while maintaining static observable or unobservable states. Stated otherwise, both demographic and geographic closure assumptions are relaxed, but all individuals are either observable or unobservable within primary periods. Within these primary periods transitions are possible among multiple observable states, but transitions are not allowed among the corresponding unobservable states. Our motivation for this work is exploring potential differences in population parameters for pond-breeding amphibians, where the quality of habitat surrounding the pond is not spatially uniform. The scenario is an example of a more general case where individuals move

    Full Text Available En español: El Graduado es una de las películas más representativas del movimiento cinematográfico denominado New Hollywood dado en Estados Unidos a finales de la década de los sesenta y principios de los setenta por varios motivos: la gran audiencia y repercusión mediática que cosechó durante su exposición cinematográfica, la diversidad que originó en el terreno de la crítica especializada y el estatus icónico que desde entonces mantiene. Basándonos en la teoría del cine de temática contemporánea como representante más o menos fiel de los acontecimientos históricos y sociales que le rodean, en este artículo analizamos la suficiencia del filme de Mike Nichols como evidencia del cambio cultural y el salto generacional dado en la época y analizamos su carácter de película revolucionaria -haciendo hincapié tanto en su relación con la contracultura como en su controvertido final- desde el punto de vista ideológico y de la caracterización de los personajes. In english: The Graduate is one of the most representative films of late sixties and early seventies cinema movement New Hollywood in the United States for several reasons: the large audience and media impact during its showing, the disagreements in the specialized criticism and the iconic status it has since then. Based on the theory of films as representations of their contemporary historical and social events, in this paper we analyze the value of Mike Nichols film as evidence of the cultural change and generation gap of the period. We analyze its revolutionary character -paying attention both to its relation with counterculture and to its controversial ending- from the ideological and character description points of view.

  13. Primary hyperparathyroidism with a low-normal, atypical serum parathyroid hormone as shown by discordant immunoassay curves. (United States)

    Lafferty, Fred W; Hamlin, Clive R; Corrado, Kristin R; Arnold, Andrew; Shuck, Jerry M


    In patients with primary hyperparathyroidism (PHP), one expects to find a serum PTH in the high or high-normal range. The presence of a low-normal PTH in PHP can be difficult to explain. Our objective was to investigate the cause of a low-normal serum PTH in a patient with PHP. A 57-yr-old asymptomatic white female from the private practice of F.W.L. presented with an 8-yr history of a rising serum calcium from 10.5-11.6 mg/dl (2.63-2.88 mmol/liter) and a low-normal serum intact PTH of 29.2 pg/ml. After localization of a parathyroid adenoma by [(18)F]fluorodesoxyglucose positron emission tomography scanning, a 120-mg parathyroid adenoma was removed with the achievement of normocalcemia for the subsequent 2 yr. Routine pre- and postoperative serum intact PTH assays were preformed at both the Quest Diagnostics regional laboratory in Pittsburgh, Pennsylvania, and at the Quest Diagnostics Nichols Institute in California. In addition, intact, biointact, and C-terminal assays were measured in undiluted, 1:2 diluted, and 1:4 diluted sera at the Nichols Institute. PTH gene sequence analysis was performed from DNA extracted both from the parathyroid adenoma and the patient's peripheral blood leukocytes. Dilution, with correction for the dilution factor, of the preoperative serum produced a progressive rise in the intact, biointact, and the C-terminal assays, whereas no dilution effect was seen in postoperative serum. No intragenic mutations in the pre-pro-PTH coding region were found in either the parathyroid adenoma or matched blood DNA samples. The discordant preoperative immunoassay curves with dilution could not be explained by the adenoma producing a mutated PTH. Furthermore, an autoantibody against the PTH produced by the adenoma is ruled out by the prompt loss of the dilution effect in the three PTH assays within 1 wk of the adenoma's excision. A posttranslational effect on the PTH molecule within the adenoma remains a possible explanation for the discordant

    Full Text Available Discussion boards provide an interactive venue where new and future language teachers can reflect, evaluate, solve problems or simply exchange ideas (e.g., Bonk, Hansen, Grabner-Hagen, Lazar, & Mirabelli, 1996; DeWert, Babinski, & Jones, 2003; Kumari, 2001; Pawan, Paulus, Yalcin, & Chang, 2003. In addition, encouraging future teachers to learn with technology before teaching with it allows them to become comfortable using various computer applications. This article examines transcripts from a semester-long asynchronous discussion between foreign language methodology classes at two different universities. Social and cognitive presence in the discussions was analyzed using Garrison, Anderson, and Archer’s Framework of a Community of Inquiry (2001. The results indicate that students engaged in a high degree of interactivity as well as all types of social and cognitive presence. These findings indicate that students not only progressed in their cognitive understanding of the pedagogical topics, but also employed social presence, the more dominant of the two, to aid their discussions. The topics seemed to play an important role in the type of cognitive activity evident in the discussions. These results differ from those of studies which found that students did not engage in interactivity (Henri, 1995; Pena-Shaff & Nicholls, 2004 and others which noted low levels of social presence (Garrison, et al. 2001; Meyer, 2003.

  17. Prediction of intention to continue sport in athlete students: A self-determination theory approach. (United States)

    Keshtidar, Mohammad; Behzadnia, Behzad


    Grounded on the self-determination theory (Deci & Ryan, 1985, 2000) and achievement goals theory (Ames, 1992; Nicholls, 1989), this study via structural equation modelling, predicted intention to continue in sport from goal orientations and motivations among athlete students. 268 athlete students (Mage = 21.9), in Iranian universities completed a multi-section questionnaire tapping the targeted variables. Structural equation modelling (SEM) offered an overall support for the proposed model. The results showed that there are positive relationships between intention to continue in sport and both orientations as well as both motivations. A task-involving orientation emerged as a positive predictor of the autonomous motivation, while an ego-involving orientation was a positive predictor controlled motivation as well as autonomous motivation. The results also support positive paths between autonomous motivation and future intention to participate in sport. Autonomous motivation also was a positive mediator in relationship between task orientation and the intentions. As a conclusion, the implications of the task-involving orientation are discussabled in the light of its importance for the quality and potential maintenance of sport involvement among athlete students.

  18. Cross-domain generality of achievement motivation across sport and the classroom: the case of Spanish adolescents. (United States)

    Castillo, Isabel; Duda, Joan L; Balaguer, Isabel; Tomás, Inés


    Drawing from contemporary social cognitive theories of achievement motivation, the relationship of personal theories of achievement (ego and task theory) with perceived ability and reported satisfaction with school and sport was examined. The cross-domain generality of these relationships in these contexts, in the case of a representative sample of adolescents between 11 and 15 years of age (N = 967, M age = 13.5, SD = 1.80; 492 girls and 475 boys) from the Valencian Community (Spain) also was examined. According to previous research in the United States (Duda & Nicholls, 1992), the findings of this study indicate a cross-domain consistency with regard to how adolescents tend to define success and their views of how achievement activities operate across sport and the classroom. However, little cross-domain generality was found for perceptions of ability and reported satisfaction. In the sport and classroom domains, a task theory was related to greater satisfaction, while an ego theory was related to greater reported boredom and low interest in the activity.
