    The circadian clock of the cyanobacterium Synechococcus elongatus can be reconstituted in vitro by the KaiA, KaiB and KaiC proteins in the presence of ATP. The principal clock component, KaiC, undergoes regular cycles between hyper- and hypo-phosphorylated states with a period of ca. 24 h that is temperature compensated. KaiA enhances KaiC phosphorylation and this enhancement is antagonized by KaiB. Throughout the cycle Kai proteins interact in a dynamic manner to form complexes of different composition. We present a three-dimensional model of the S. elongatus KaiB-KaiC complex based on X-ray crystallography, negative-stain and cryo-electron microscopy, native gel electrophoresis and modelling techniques. We provide experimental evidence that KaiB dimers interact with KaiC from the same side as KaiA and for a conformational rearrangement of the C-terminal regions of KaiC subunits. The enlarged central channel and thus KaiC subunit separation in the C-terminal ring of the hexamer is consistent with KaiC subunit exchange during the dephosphorylation phase. The proposed binding mode of KaiB explains the observation of simultaneous binding of KaiA and KaiB to KaiC, and provides insight into the mechanism of KaiB's antagonism of KaiA.

  4. CryoEM and Molecular Dynamics of the Circadian KaiB-KaiC Complex Indicates That KaiB Monomers Interact with KaiC and Block ATP Binding Clefts

    The circadian control of cellular processes in cyanobacteria is regulated by a posttranslational oscillator formed by three Kai proteins. During the oscillator cycle, KaiA serves to promote autophosphorylation of KaiC while KaiB counteracts this effect. Here, we present a crystallographic structure of the wild-type Synechococcus elongatus KaiB and a cryo-electron microscopy (cryoEM) structure of a KaiBC complex. The crystal structure shows the expected dimer core structure and significant conformational variations of the KaiB C-terminal region, which is functionally important in maintaining rhythmicity. The KaiBC sample was formed with a C-terminally truncated form of KaiC, KaiC-Δ489, which is persistently phosphorylated. The KaiB–KaiC-Δ489 structure reveals that the KaiC hexamer can bind six monomers of KaiB, which form a continuous ring of density in the KaiBC complex. We performed cryoEM-guided molecular dynamics flexible fitting simulations with crystal structures of KaiB and KaiC to probe the KaiBC protein–protein interface. This analysis indicated a favorable binding mode for the KaiB monomer on the CII end of KaiC, involving two adjacent KaiC subunits and spanning an ATP binding cleft. A KaiC mutation, R468C, which has been shown to affect the affinity of KaiB for KaiC and lengthen the period in a bioluminescence rhythm assay, is found within the middle of the predicted KaiBC interface. The proposed KaiB binding mode blocks access to the ATP binding cleft in the CII ring of KaiC, which provides insight into how KaiB might influence the phosphorylation status of KaiC.

    The molecular machinery of the cyanobacterial circadian clock consists of three proteins: KaiA, KaiB, and KaiC. Through interactions among the three Kai proteins, the phosphorylation states of KaiC generate circadian oscillations in vitro in the presence of ATP. Here, we characterized the complex formation between KaiB and KaiC using a phospho-mimicking mutant of KaiC, which had an aspartate substitution at the Ser431 phosphorylation site and exhibited optimal binding to KaiB. Mass-spectrometric titration data showed that the proteins formed a complex exclusively in a 6:6 stoichiometry, indicating that KaiB bound to the KaiC hexamer with strong positive cooperativity. The inverse contrast-matching technique of small-angle neutron scattering enabled selective observation of KaiB in complex with the KaiC mutant with partial deuteration. It revealed a disk-shaped arrangement of the KaiB subunits on the outer surface of the KaiC C1 ring, which also serves as the interaction site for SasA, a histidine kinase that operates as a clock-output protein in the regulation of circadian transcription. These data suggest that cooperatively binding KaiB competes with SasA with respect to interaction with KaiC, thereby promoting the synergistic release of this clock-output protein from the circadian oscillator complex.

  4. Circadian KaiC phosphorylation: a multi-layer network.

    Congxin Li

    2009-11-01

    Full Text Available Circadian KaiC phosphorylation in cyanobacteria reconstituted in vitro recently initiates a series of studies experimentally and theoretically to explore its mechanism. In this paper, we report a dynamic diversity in hexameric KaiC phosphoforms using a multi-layer reaction network based on the nonequivalence of the dual phosphorylation sites (S431 and T432 in each KaiC subunit. These diverse oscillatory profiles can generate a kaleidoscopic phase modulation pattern probably responsible for the genome-wide transcription rhythms directly and/or indirectly in cyanobacteria. Particularly, our model reveals that a single KaiC hexamer is an energy-based, phosphorylation-dependent and self-regulated circadian oscillator modulated by KaiA and KaiB. We suggest that T432 is the main regulator for the oscillation amplitude, while S431 is the major phase regulator. S431 and T432 coordinately control the phosphorylation period. Robustness of the Kai network was examined by mixing samples in different phases, and varying protein concentrations and temperature. Similar results were obtained regardless of the deterministic or stochastic method employed. Therefore, the dynamic diversities and robustness of Kai oscillator make it a qualified core pacemaker that controls the cellular processes in cyanobacteria pervasively and accurately.

  7. Richard Feynman and computation

    1999-04-01

    The enormous contribution of Richard Feynman to modern physics is well known, both to teaching through his famous Feynman Lectures on Physics, and to research with his Feynman diagram approach to quantum field theory and his path integral formulation of quantum mechanics. Less well known perhaps is his long-standing interest in the physics of computation and this is the subject of this paper. Feynman lectured on computation at Caltech for most of the last decade of his life, first with John Hopfield and Carver Mead, and then with Gerry Sussman. The story of how these lectures came to be written up as the Feynman Lectures on Computation is briefly recounted. Feynman also discussed the fundamentals of computation with other legendary figures of the computer science and physics community such as Ed Fredkin, Rolf Landauer, Carver Mead, Marvin Minsky and John Wheeler. He was also instrumental in stimulating developments in both nanotechnology and quantum computing. During the 1980s Feynman re-visited long-standing interests both in parallel computing with Geoffrey Fox and Danny Hillis, and in reversible computation and quantum computing with Charles Bennett, Norman Margolus, Tom Toffoli and Wojciech Zurek. This paper records Feynman's links with the computational community and includes some reminiscences about his involvement with the fundamentals of computing.

  8. Richard Rorty in Context

    Directory of Open Access Journals (Sweden)

    Brian Lloyd

    2013-08-01

    Full Text Available Richard Rorty was a strong contextualist in his approach to philosophical and political ideas, yet his own most characteristic arguments are typically evaluated without much reference to the historical circumstances that provoked them. A key participant in the post-1980 revival of pragmatism within North American and European intellectual circles, Rorty reaffirmed the strong connections between American pragmatism and German idealism. This move placed him at odds with scholars who forged the unity of pragmatism—united John Dewey and William James—under the banner of radical empiricism. Those engaged most enthusiastically in celebrating Rorty’s achievements, in short, defend a conception of pragmatism that Rorty sharply criticized and ideas about the history of philosophy that he did not share. His distinctive intellectual agenda is best appreciated after setting it in the context of the history of the American Left and, more specifically, the reckoning with the tumultuous 1960s that animates so many ongoing debates—inside and outside the academy—about cultural and political affairs.

    Lack of food security is one of the major nutrition issues facing Māori today. Loss of traditional kai (food) gathering places and practices following colonisation and urbanisation has impacted negatively on food security for Māori. This paper explores the role of Māori in enhancing Māori food security through revitalising traditional kai. A narrative literature review of peer reviewed and grey literature on revitalising traditional kai for Māori was conducted. The focus was on two areas: increasing the availability of traditional kai to Māori households (such as through replenishing fish stocks, and gardening projects) and increasing the financial means available to Māori households to purchase food (by economic development of traditional kai industries and employment creation). A range of activities to improve food security for Māori by revitalising traditional kai was identified in the literature. Māori are now significant players in New Zealand's fishing industry, and are developing their horticultural resources. Gardening initiatives have also grown considerably in Māori communities. Enabling factors included: the return of traditional kai resources by the Crown, and successful pursuit by Māori of the legal rights to develop them; development of Māori models of governance; government policy around Māori economic development and healthy eating; and Māori leadership on the issue. Barriers to revitalising traditional kai that remain to be addressed include: tensions between Government and Māori goals and models of resource management; economic pressures resulting in severely depleted fishing stocks; and pollution of marine and freshwater fish. Revitalising traditional kai has considerable potential to improve food security for Māori, both directly in terms of food supply and by providing income, and warrants policy and practical support. These findings have implications for other indigenous cultures who are struggling to be food secure. © The

    Cyanobacteria have been shown to have a circadian clock system that consists mainly of three protein components: KaiA, KaiB and KaiC. This system is well understood in the cyanobacterium Synechococcus elongatus PCC 7942, for which robust circadian oscillations have been shown. Like many other cyanobacteria, the chromosome of the model cyanobacterium Synechocystis sp. PCC 6803 contains additional kaiC and kaiB gene copies besides the standard kaiABC gene cluster. The respective gene products differ significantly in their amino acid sequences, especially in their C-terminal regions, suggesting different functional characteristics. Here, phosphorylation assays of the three Synechocystis sp. PCC 6803 KaiC proteins revealed that KaiC1 phosphorylation depends on KaiA, as is well documented for the Synechococcus elongatus PCC 7942 KaiC protein, whereas KaiC2 and KaiC3 autophosphorylate independently of KaiA. This was confirmed by in vivo protein-protein interaction studies, which demonstrate that only KaiC1 interacts with KaiA. Furthermore, we demonstrate that the three different Kai proteins form only homomeric complexes in vivo. As only KaiC1 phosphorylation depends on KaiA, a prerequisite for robust oscillations, we suggest that the kaiAB1C1 gene cluster in Synechocystis sp. PCC 6803 controls circadian timing in a manner similar to the clock described in Synechococcus elongatus PCC 7942.

  19. A thermodynamically consistent model of the post-translational Kai circadian clock

    Science.gov (United States)

    Lubensky, David K.; ten Wolde, Pieter Rein

    2017-01-01

    The principal pacemaker of the circadian clock of the cyanobacterium S. elongatus is a protein phosphorylation cycle consisting of three proteins, KaiA, KaiB and KaiC. KaiC forms a homohexamer, with each monomer consisting of two domains, CI and CII. Both domains can bind and hydrolyze ATP, but only the CII domain can be phosphorylated, at two residues, in a well-defined sequence. While this system has been studied extensively, how the clock is driven thermodynamically has remained elusive. Inspired by recent experimental observations and building on ideas from previous mathematical models, we present a new, thermodynamically consistent, statistical-mechanical model of the clock. At its heart are two main ideas: i) ATP hydrolysis in the CI domain provides the thermodynamic driving force for the clock, switching KaiC between an active conformational state in which its phosphorylation level tends to rise and an inactive one in which it tends to fall; ii) phosphorylation of the CII domain provides the timer for the hydrolysis in the CI domain. The model also naturally explains how KaiA, by acting as a nucleotide exchange factor, can stimulate phosphorylation of KaiC, and how the differential affinity of KaiA for the different KaiC phosphoforms generates the characteristic temporal order of KaiC phosphorylation. As the phosphorylation level in the CII domain rises, the release of ADP from CI slows down, making the inactive conformational state of KaiC more stable. In the inactive state, KaiC binds KaiB, which not only stabilizes this state further, but also leads to the sequestration of KaiA, and hence to KaiC dephosphorylation. Using a dedicated kinetic Monte Carlo algorithm, which makes it possible to efficiently simulate this system consisting of more than a billion reactions, we show that the model can describe a wealth of experimental data.

    Full Text Available Introduction. Uveal melanoma (UM is an intraocular tumor that leads to metastatic disease in approximately 50% of afflicted patients. There is no efficacious treatment for metastatic disease in this cancer. Identification of markers that can offer prognostic and therapeutic value is a major focus in this field at present. KAI1 is a metastasis suppressor gene that has been reported to play a role in various human malignancies, although it has not previously been evaluated in UM. Purpose. To investigate the expression of KAI1 in UM and its potential value as a prognostic marker. Materials and Methods. 18 cases of human primary UM were collected and immunostained for KAI1 expression. A pathologist evaluated staining intensity and distribution semiquantitatively. Each case was categorized as group 1 (low staining or group 2 (high staining. Results. In group 2, two of the 12 cases presented with metastasis. Conversely, in group 1, five out of 6 cases had metastasis. The mean follow-up of patients who did not develop metastasis was 81.81 months (median: 75 months versus 42.14 months (median: 44 months for patients with metastasis. Conclusions. KAI1 is a promising candidate marker that may offer prognostic value in UM; it may also represent a therapeutic target in metastatic disease.

  7. Richard's back: death, scoliosis and myth making.

    Science.gov (United States)

    Lund, Mary Ann

    2015-12-01

    The body of a mediaeval monarch was always under scrutiny, and Richard III's was no exception. In death, however, his body became subject to new forms of examination and interpretation: stripped naked after the battle of Bosworth, his corpse was carried to Leicester and exhibited before being buried. In 2012, it was rediscovered. The revelation that Richard suffered from scoliosis prompts this article to re-evaluate the historical sources about Richard's physique and his posthumous reputation. This article argues that Richard's death and his myth as 'crookback' are inextricably linked and traces attitudes to spinal curvature in the early modern period. It also considers how Shakespeare represented Richard as deformed, and aspects of performance history which suggest physical vulnerability. It then considers Richard's scoliosis from the perspective of medical history, reviewing classical accounts of scoliosis and arguing that Richard was probably treated with a mixture of axial traction and pressure. It demonstrates from the evidence of Richard's medical household that he was well placed to receive hands-on therapies and considers in particular the role of his physician and surgeon, William Hobbes. Finally, it shows how the case of Richard III demonstrates the close relationship between politics and medicine in the period and the contorted process of historical myth making.

    AIM: To investigate KAI1 gene expression in the progression of human colonic carcinoma and its clinical significances.METHODS: KAI1 expression was detected by in situ hybridization and immunohistochemistry in the 4 established cell lines of colorectal carcinoma with different metastatic potentials, and in 80 specimens of colonic carcinoma, 21 colonic carcinoma specimens with lymphatic metastasis and 20 controls of normal colonic mucosa.RESULTS: The expressions of KAI1 in HT29 and SW480 cell lines were higher than those in LoVo and SW620. The expression of KAI1 gene was significantly higher in colorectal carcinoma compared with normal colonic mucosa and lymphatic metastasis (X2=46.838, P<0.01). The expression of KAI1 gene had no relationship with histological grade.The KAI1 expressions in Dukes A and B carcinoma were higher at both mRNA and protein levels compared to Dukes C carcinoma (X2=16.061, P<0.05). The expression of KAI1 in colonic carcinoma specimens with lymphatic metastasis was almost lost. The results of in situ hybridization were in concordance with immunohistochemistry.CONCLUSION: KAI1 is highly related to the metastasis of colonic carcinoma and may be a useful indicator of metastasis in colonic carcinoma.

    BACKGROUND: KAI1/CD82 has been reported to attenuate the process of metastases in a variety of tumors; however, its mechanism of action in invasion has not been fully elucidated. The present study aimed to investigate the importance of KAI1 in invasion and its correlation with activation of sphingosine kinase (SPK) in human pancreatic cancer PANC1 and Miapaca-2 cell lines. METHODS: The expression of KAI1 in PANC1 and Miapaca-2 cells,whichwasmediatedbyrecombinantadenovirus(Ad-KAI1), was assessed by a flow cytometer and Western blotting. After successful infection was established, in vitro growth curve and invasive ability in Boyden Chamber assay were studied. The presence of KAI1 correlating with c-Met and SPK was detected by co-immunoprecipitationand[γ-32P]ATPincorporation. RESULTS: KAI1 genes had no significant effects on the curve representing cell growth. After infection with the KAI1 gene, decreased invasive ability in the Boyden Chamber assay was observed in PANC1 and Miapaca-2 cells that were induced by hepatocyte growth factor. Over-expression of KAI1 in the cells led to the deactivation of SPK and a decreased level of intracellular sphingosine-1-phosphate. No correlation was observed between c-Met and KAI1 during co-immunoprecipitation. CONCLUSION: The results of this study for the first time demonstrated a regulatory role for KAI1 in SPK activation, which leads to decreased invasive ability in disease progression of human pancreatic cancer.

  20. Evidence that KARRIKIN-INSENSITIVE2 (KAI2 receptors may perceive an unknown signal that is not karrikin or strigolactone

    Directory of Open Access Journals (Sweden)

    Full Text Available The α/β-hydrolases KAI2 and D14 are paralogous receptors for karrikins and strigolactones, two classes of plant growth regulators with butenolide moieties. KAI2 and D14 act in parallel signaling pathways that share a requirement for the F-box protein MAX2, but produce distinct growth responses by targeting different members of the SMAX1-LIKE/D53 family. kai2 and max2 mutants share seed germination, seedling growth, leaf shape, and petiole orientation phenotypes that are not found in d14 or SL-deficient mutants. This implies that KAI2 recognizes an unknown, endogenous signal, herein termed KAI2 ligand (KL. Recent studies of ligand-specificity among KAI2 paralogs in basal land plants and root parasitic plants suggest that karrikin and strigolactone perception are evolutionary adaptations of KL receptors. Here we demonstrate that evolutionarily conserved KAI2c genes from two parasite species rescue multiple phenotypes of the Arabidopsis kai2 mutant, unlike karrikin- and strigolactone-specific KAI2 paralogs. We hypothesize that KAI2c proteins recognize KL, which could be an undiscovered hormone.

    Full Text Available The cell surface glycoprotein KAI1/CD82 suppresses tumor growth and metastasis in animal models. This study aimed to evaluate the prognostic relevance of KAI1/CD82 protein expression in human gastric cancer. Primary gastric carcinomas (n = 271 with amean clinical follow-up time of 48months were immunostained using the monoclonal anti-KAI1/CD82 antibody G2. Staining was evaluated as negative versus positive for statistical analysis. KAI1/CD82 immunoreactivity was absent in 103/271 (38% cases. There was a trend towards KAI1/CD82 negativity in poorly differentiated cases (p = 0.0679. Moreover, KAI1/CD82-negative carcinomas were associated with a higher pT status (p = 0.0222, metastatic lymph node involvement (p = 0.0018 and a higher clinical tumor stage (p = 0.0050. The median overall survival times of KAI1/CD82-negative and KAI1/CD82-positive gastric carcinomas were 20 and 37 months, respectively (p = 0.2305. These results are in line with the proposed function of KAI1/CD82 as a suppressor of tumor growth and metastasis. However, these data suggest that KAI1/CD82, as detected by immunohistochemistry, is of limited value as a prognostic marker for gastric cancer in routine histological workup.

    2004-12-01

    Richard Joseph Elston, known for his development of innovative astronomical instrumentation, died on 26 January 2004 in Gainesville, Florida, after a four-year battle with Hodgkin's lymphoma. A professor of astronomy at the University of Florida, Richard had an unusually broad range of interests and skills, and a willingness to share his passion for astronomy with others, which made him a highly valued member of the astronomical community. Born 1 July 1960, in Albuquerque, New Mexico, Richard was the son of a geologist father and journalist mother. His childhood interest in astronomy and instrumentation matured as he majored in physics and astronomy at the University of New Mexico (BS, 1983) under the mentorship of Michael Zeilik. Richard pursued his PhD in astronomy at the University of Arizona and earned his degree in 1988. He pioneered the use of IR arrays for deep imaging surveys of the sky to study galaxy formation, and completed his thesis Search for Rapidly Forming Galaxies at High Redshift under the direction of George Rieke. Richard's graduate work included the first detection of galaxies at intermediate redshifts with evolved populations too red to have been identifiable from optical imaging surveys alone. In the Astrophysical Journal Letters in 1988, he, George Rieke, and Marcia Rieke reported the discovery of this new class of galaxies, now known as EROs (Extremely Red Objects), important as the possible progenitors of present day elliptical galaxies. Following post-doctoral positions at Kitt Peak National Observatory from 1988 to 1991 and at the Observatories of the Carnegie Institution of Washington from 1991 to 1992, Richard joined the scientific staff of Cerro Tololo Inter-American Observatory in Chile, part of the NSF's National Optical Astronomy Observatory. By 1994, he had become head of CTIO's IR instrumentation program and was leading the development of new instruments for the US astronomical community. In 1996, Richard married astronomer

    2008-01-01

    We conducted a study concerning the suppressive mechanism of KAI1/CD82 on hepatoma cell metas-tasis. Hepatocyte growth factor (HGF) induces the migration of hepatoma cells through activation of cellular sphingosine kinase 1 (SphK1). Adenovirus-mediated gene transfer of KAI1 (Ad-KAI1) down-regulates the SphK1 expression and suppresses the HGF-induced migration of SMMC-7721 human hepatocellcular carcinoma cells. Overexpression of KAI1/CD82 significantly elevates Sprouty2 at the protein level. Ablation of Sprouty2 with RNA interference can block the KAI1/CD82-induced suppres-sion of hepatoma cell migration and downregulation of SphK1 expression. It is demonstrated that KAI1/CD82 suppresses HGF-induced migration of hepatoma cells via upregulation of Sprouty2.

  18. Computational modeling of protein interactions and phosphoform kinetics in the KaiABC cyanobacterial circadian clock

    CERN Document Server

    Byrne, Mark

    2014-01-01

    The KaiABC circadian clock from cyanobacteria is the only known three-protein oscillatory system which can be reconstituted outside the cell and which displays sustained periodic dynamics in various molecular state variables. Despite many recent experimental and theoretical studies there are several open questions regarding the central mechanism(s) responsible for creating this ~24 hour clock in terms of molecular assembly/disassembly of the proteins and site-dependent phosphorylation and dephosphorylation of KaiC monomers. Simulations of protein-protein interactions and phosphorylation reactions constrained by analytical fits to partial reaction experimental data support the central mechanism of oscillation as KaiB-induced KaiA sequestration in KaiABC complexes associated with the extent of Ser431 phosphorylation in KaiC hexamers. A simple two-state deterministic model in terms of the degree of phosphorylation of Ser431 and Thr432 sites alone can reproduce the previously observed circadian oscillation in the...

  19. Detecting KaiC phosphorylation rhythms of the cyanobacterial circadian oscillator in vitro and in vivo

    Science.gov (United States)

    Kim, Yong-Ick; Boyd, Joseph S.; Espinosa, Javier; Golden, Susan S.

    2016-01-01

    The central oscillator of the cyanobacterial circadian clock is unique in the biochemical simplicity of its components and the robustness of the oscillation. The oscillator is composed of three cyanobacterial proteins, KaiA, KaiB, and KaiC. If very pure preparations of these three proteins are mixed in a test tube in the right proportions and with ATP and MgCl2, the phosphorylation states of KaiC will oscillate with a circadian period and these states can be analyzed simply by SDS-PAGE. The purity of the proteins is critical for obtaining robust oscillation. Contaminating proteases will destroy oscillation by degradation of Kai proteins, and ATPases will attenuate robustness by consumption of ATP. Here, we provide a detailed protocol to obtain pure recombinant proteins from Escherichia coli to construct a robust cyanobacterial circadian oscillator in vitro. In addition, we present a protocol that facilitates analysis of phosphoryation states of KaiC and other phosphorylated proteins from in vivo samples. PMID:25662456

  20. Method of lines solution of Richards` equation

    Energy Technology Data Exchange (ETDEWEB)

    1996-12-31

    We consider the method of lines solution of Richard`s equation, which models flow through porous media, as an example of a situation in which the method can give incorrect results because of premature termination of the nonlinear corrector iteration. This premature termination arises when the solution has a sharp moving front and the Jacobian is ill-conditioned. While this problem can be solved by tightening the tolerances provided to the ODE or DAE solver used for the temporal integration, it is more efficient to modify the termination criteria of the nonlinear solver and/or recompute the Jacobian more frequently. In this paper we continue previous work on this topic by analyzing the modifications in more detail and giving a strategy on how the modifications can be turned on and off in response to changes in the character of the solution.

    Full Text Available KARRIKIN INSENSITIVE 2 (KAI2 is an α/β hydrolase involved in seed germination and seedling development. It is essential for plant responses to karrikins, a class of butenolide compounds derived from burnt plant material that are structurally similar to strigolactone plant hormones. The mechanistic basis for the function of KAI2 in plant development remains unclear. We have determined the crystal structure of Arabidopsis thaliana KAI2 in space groups P2(1 2(1 2(1 (a =63.57 Å, b =66.26 Å, c =78.25 Å and P2(1 (a =50.20 Å, b =56.04 Å, c =52.43 Å, β =116.12° to 1.55 and 2.11 Å respectively. The catalytic residues are positioned within a large hydrophobic pocket similar to that of DAD2, a protein required for strigolactone response in Petunia hybrida. KAI2 possesses a second solvent-accessible pocket, adjacent to the active site cavity, which offers the possibility of allosteric regulation. The structure of KAI2 is consistent with its designation as a serine hydrolase, as well as previous data implicating the protein in karrikin and strigolactone signalling.

This brash New York-born American physicist startled the more conservative giants of European physics with his endless ability to improvise. Indeed, later in life, Feynman became an accomplished bongo player. Feynman's legacy to physics was his ability to simplify complex equations and clarify fundamental principles through the use of graphs.

    Richard von Volkmann (1830-1889), one of the most important surgeons of the 19(th) century, is regarded as one of the fathers of orthopaedic surgery. He was a contemporary of Langenbeck, Esmarch, Lister, Billroth, Kocher, and Trendelenburg. He was head of the Department of Surgery at the University of Halle, Germany (1867-1889). His popularity attracted doctors and patients from all over the world. He was the lead physician for the German military during two wars. From this experience, he compared the mortality of civilian and war injuries and investigated the general poor hygienic conditions in civilian hospitals. This led him to introduce the "antiseptic technique" to Germany that was developed by Lister. His powers of observation and creativity led him to findings and achievements that to this day bear his name: Volkmann's contracture and the Hueter-Volkmann law. Additionally, he was a gifted writer; he published not only scientific literature but also books of children's fairy tales and poems under the pen name of Richard Leander, assuring him a permanent place in the world of literature as well as orthopaedics.

It’s the time of the fall of every certainty, is the era of “post”, after the tradition, after metaphysics, after the truth, and that requires more effort than any other constant reflection. The neopragmatismo seems to be an effective investigative tool for conducting this reflection and a vantage point to carry on a conversation around the issues of education. In particular, the author intended to refer to the work of Richard Rorty, the author who more than others reflected on the encounter between two important pragmatist tradition: that of classical pragmatism and the “continental” or responsible for the development of a new European concept of truth, understood as a critical and interpretative.

  17. Evaluation from Richard Rorty's Point of View

    Full Text Available Abstract Communitarianism is one of the main critics of moral-political theory of liberalism. According to communitarians, liberalism presupposes an image of human identity which does not do justice to the collective ties between human being. It ignores altruist duties and common loyalties to traditional, historical values by inappropriately insisting on priority of justice from an individualist point of view, culminating in advent of ignoble, egoist characters unfamiliar with collective values. In this essay, firstly, I would elaborate these critiques and then try to answer them from Richard Rorty's point of view. Though Rorty agrees with the communitarians' claim that community makes a constitutive contribution to the identity of individuals, he believes that the pragmatist pole of contemporary liberalism is not subject to the communitarian objections. He tries to show that 20th century political liberalism, best formulated by John Dewy and John Rawls, is immune to communitarian critiques because of its consistency with historicism and ethnocentrism.

    The expression of KAI1/CD82 and MRP-1/CD9 in transitional cell carcinoma of bladder (TCCB) and its clinical significance were investigated. Immunohistochemistry was used to detect KAI1/CD82 and MRP-1/CD9 protein expression in 52 TCCB specimens. Correlation between the expression of KAI1/CD82 and MRP-1/CD9 to clinicopathologic factors was statistically analyzed. The results showed that the positive rate of KAI1/CD82 and MRP-1/CD9 in TCCB was 50% and 61.5%, respectively. The MRP-1/CD9 and KAI1/CD82 expression was significantly associated with grade of TCCB (PMRP-1/CD9 or KAI1/CD82 expression and clinical stage of TCCB (P>0.05). The expression level of MRP-1/CD9 and KAI1/CD82 in recurrent TCCB samples was lower than that in non-recurrent samples (PMRP-1/CD9 expression was statistically significant (r=0.316, PMRP-1/CD9 expression may be important prognostic indicators and potentially useful for assessing the biological behavior of TCCB.

  3. KAI1 suppresses HIF-1α and VEGF expression by blocking CDCP1-enhanced Src activation in prostate cancer

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available Abstract Background KAI1 was initially identified as a metastasis-suppressor gene in prostate cancer. It is a member of the tetraspan transmembrane superfamily (TM4SF of membrane glycoproteins. As part of a tetraspanin-enriched microdomain (TEM, KAI1 inhibits tumor metastasis by negative regulation of Src. However, the underlying regulatory mechanism has not yet been fully elucidated. CUB-domain-containing protein 1 (CDCP1, which was previously known as tetraspanin-interacting protein in TEM, promoted metastasis via enhancement of Src activity. To better understand how KAI1 is involved in the negative regulation of Src, we here examined the function of KAI1 in CDCP1-mediated Src kinase activation and the consequences of this process, focusing on HIF-1 α and VEGF expression. Methods We used the human prostate cancer cell line PC3 which was devoid of KAI1 expression. Vector-transfected cells (PC3-GFP clone #8 and KAI1-expressing PC3 clones (PC3-KAI1 clone #5 and #6 were picked after stable transfection with KAI1 cDNA and selection in 800 μg/ml G418. Protein levels were assessed by immunoblotting and VEGF reporter gene activity was measured by assaying luciferase activitiy. We followed tumor growth in vivo and immunohistochemistry was performed for detection of HIF-1, CDCP1, and VHL protein level. Results We demonstrated that Hypoxia-inducible factor 1α (HIF-1α and VEGF expression were significantly inhibited by restoration of KAI1 in PC3 cells. In response to KAI1 expression, CDCP1-enhanced Src activation was down-regulated and the level of von Hippel-Lindau (VHL protein was significantly increased. In an in vivo xenograft model, KAI1 inhibited the expression of CDCP1 and HIF-1α. Conclusions These novel observations may indicate that KAI1 exerts profound metastasis-suppressor activity in the tumor malignancy process via inhibition of CDCP1-mediated Src activation, followed by VHL-induced HIF-1α degradation and, ultimately, decreased VEGF

    The circadian clock of the cyanobacterium Synechococcus elongatus can be reconstituted in vitro by three proteins, KaiA, KaiB and KaiC. Homo-hexameric KaiC displays kinase, phosphatase and ATPase activities; KaiA enhances KaiC phosphorylation and KaiB antagonizes KaiA. Phosphorylation and dephosphorylation of the two known sites in the C-terminal half of KaiC subunits, T432 and S431, follow a strict order (TS {yields} pTS {yields} pTpS {yields} TpS {yields} TS) over the daily cycle, the origin of which is not understood. To address this void and to analyze the roles of KaiC active site residues, in particular T426, we determined structures of single and double P-site mutants of S. elongatus KaiC. The conformations of the loop region harboring P-site residues T432 and S431 in the crystal structures of six KaiC mutant proteins exhibit subtle differences that result in various distances between Thr (or Ala/Asn/Glu) and Ser (or Ala/Asp) residues and the ATP {gamma}-phosphate. T432 is phosphorylated first because it lies consistently closer to P{gamma}. The structures of the S431A and T432E/S431A mutants reveal phosphorylation at T426. The environments of the latter residue in the structures and functional data for T426 mutants in vitro and in vivo imply a role in dephosphorylation. We provide evidence for a third phosphorylation site in KaiC at T426. T426 and S431 are closely spaced and a KaiC subunit cannot carry phosphates at both sites simultaneously. Fewer subunits are phosphorylated at T426 in the two KaiC mutants compared to phosphorylated T432 and/or S431 residues in the structures of wt and other mutant KaiCs, suggesting that T426 phosphorylation may be labile. The structures combined with functional data for a host of KaiC mutant proteins help rationalize why S431 trails T432 in the loss of its phosphate and shed light on the mechanisms of the KaiC kinase, ATPase and phosphatase activities.

    The coordination of biological activities into daily cycles provides an important advantage for the fitness of diverse organisms. Most eukaryotes possess an internal clock ticking with a periodicity of about one day to anticipate sunrise and sunset. The 24-hour period of the free-running rhythm is highly robust against many changes in the natural environment. Among prokaryotes, only Cyanobacteria are known to harbor such a circadian clock. Its core oscillator consists of just three proteins, KaiA, KaiB, and KaiC that produce 24-hour oscillations of KaiC phosphorylation, even in vitro. This unique three-protein oscillator is well documented for the freshwater cyanobacterium Synechococcus elongatus PCC 7942. Several physiological studies demonstrate a circadian clock also for other Cyanobacteria including marine species. Genes for the core clock components are present in nearly all marine cyanobacterial species, though there are large differences in the specific composition of these genes. In the first section of this review we summarize data on the model circadian clock from S. elongatus PCC 7942 and compare it to the reduced clock system of the marine cyanobacterium Prochlorococcus marinus MED4. In the second part we discuss the diversity of timing mechanisms in other marine Cyanobacteria with regard to the presence or absence of different components of the clock.

    Research highlights: {yields} We first investigate the effects of KAI1 on autophagy in MiaPaCa-2 cells. {yields} Our findings demonstrate that KAI1 induces autophagy, which in turn inhibits KAI1-induced apoptosis. {yields} This study also supplies a possible novel therapeutic method for the treatment of pancreatic cancer using autophagy inhibitors. -- Abstract: KAI1, a metastasis-suppressor gene belonging to the tetraspanin family, is known to inhibit cancer metastasis without affecting the primary tumorigenicity by inhibiting the epidermal growth factor (EGF) signaling pathway. Recent studies have shown that hypoxic conditions of solid tumors induce high-level autophagy and KAI1 expression. However, the relationship between autophagy and KAI1 remains unclear. By using transmission electron microscopy, confocal microscopy, and Western blotting, we found that KAI1 can induce autophagy in a dose- and time-dependent manner in the human pancreatic cell line MiaPaCa-2. KAI1-induced autophagy was confirmed by the expression of autophagy-related proteins LC3 and Beclin 1. KAI1 induces autophagy through phosphorylation of extracellular signal-related kinases rather than that of AKT. KAI1-induced autophagy protects MiaPaCa-2 cells from apoptosis and proliferation inhibition partially through the downregulation of poly [adenosine diphosphate (ADP)-ribose] polymerase (PARP) cleavage and caspase-3 activation.

He was active in sports and band and graduated in 1959. After completing a BS at Kansas State, and a Master's degree in Divinity at Union Seminary in NY, he further studied astrophysics, receiving his doctorate from University of Washington in 1973. When Dick arrived at the University of Missouri-St. Louis in 1975, he was the only astronomer in the Department of Physics. He built the astronomy program and initiated the B.S. in physics with an astrophysics option that the majority of physics majors choose. Dick was a wonderful teacher and provided outstanding leadership to the campus. He designed and provided oversight on the construction of the campus observatory that was completed in 1981. Since that time the observatory has served as both a teaching and research facility. It is also used for monthly public open houses that draw hundreds of people annually to the campus to view the moon, stars, and planets. Upon his retirement in 2003, the Board of Curators approved naming the campus observatory the "Richard D. Schwartz Observatory" in honor of his distinctive service to the University of Missouri-St. Louis. Just as important as Dick's service to promote public interest in astronomy was his effort to make the campus observatory a research facility. Dick equipped and maintained the observatory with state-of-art detectors that allowed students to get their first taste of scientific research. From 1991-2003, he managed the campus program for the NASA/Missouri Space Grant Consortium and mentored over 30 research students in projects at the observatory. Some of the results have been published in astronomical journals. Many of those students went on to graduate schools and several have achieved tenure and distinction at major universities. In addition to Dick's service to the University

    Objective: To investigate the expressions of KAI1 and CD44v6 in human osteosarcoma and the relationship between expressions of them and their clinic pathological features and prognosis. Methods: The expressions of KAI1 and CD44v6 in 87 samples with osteosarcema were detected by S-P immunohistochemistry. Results: Expression of KAI1 had correlation with metastasis of osteosarcoma, and was strongly associated with differentiation of tumor cells. The expression of CD44v6 in osteosarcoma had correlation with metastasis. There was no difference between the expression of KAI1 and CD44v6. Cox model analysis showed that the prognostic factors were KAI1 expression, metastasis and Enneking surgical staging system. Conclusion: The abnormal expression of KAI1 and CD44v6 participate metastasis of osteosarcoma, KAI1 expression, metastasis and Enneking surgical staging system can be used to independently predict the prognosis of osteo-sarcoma patients.

  14. Richard Murphy: Autobiography and the Connemara landscape

    Directory of Open Access Journals (Sweden)

    Elsa Meihuizen

    2015-06-01

    Full Text Available It could be argued that an important feature of Richard Murphy’s work, and of his identity as a poet is the relationship between the creative self and a particular place, where ‘place’ should be understood as referring not just to physical qualities of the natural environment, but in a broader sense to denote an environment in which everything is interrelated and connected, and in which there is no sharp division between the natural and the human. The landscape providing inspiration for Murphy’s poetic imagination is the landscapes and seascapes of Connemara in north-west Ireland. In 1959 he settled in this environment which was to be his base for the next 20 years and from this period and this location emanated the bulk of his poetic oeuvre. For Murphy committing to a life of writing poetry necessarily means being in the Connemara landscape. Returning to this environment in adulthood represents a quest for recovering childhood feelings, of belonging and love, as connected to particular places. Murphy’s Connemara poems could be read as an account of this process of re-placement, as a type of autobiographical text in which the artist creates a ‘double portrait’: in writing about the landscape he also writes about himself, creating a place-portrait which is, at the same time, a self-portrait.

  15. Richard Murphy: a life in writing

    Directory of Open Access Journals (Sweden)

    E. Meihuizen

    2006-07-01

    Full Text Available The Irish poet Richard Murphy published his autobiography “The kick: a life among writers” in 2003. From a slightly different perspective the subtitle of this work could be rewritten as “A life in writing” since it is an account of the agencies that moulded a life devoted to creative writing which forms the book’s essential impetus. The memoir is based on notebooks which Murphy kept throughout his life “to hold the scraps of verse, elusive images, dreams, desires and revelations” to be developed into poetry. Apart from contextualising his poetry by registering the relationships, circumstances and landscapes from which it germinated, Murphy also tells of the creative process itself and the personal poetics underlying this process. This article explores what is regarded as the central determining feature of Murphy’s identity as poet, namely the relationship between the creative self and a particular place, where the concept of “place” is seen as a cultural palimpsest which represents not only physical qualities, but also the shaping and development of the landscape through time according to a certain way of life.

  3. Modeled Oceanic Response and Sea Surface Cooling to Typhoon Kai-Tak

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available An ocean response to typhoon Kai-Tak is simulated using an accurate fourth-order, basin-scale ocean model. The surface winds of typhoon Kai-Tak were obtained from QuikSCAT satellite images blended with the ECMWF wind fields. An intense nonlinear mesoscale eddy is generated in the northeast South China Sea (SCS with a Rossby number of O(1 and on a 50 - 100 km horizontal scale. Inertial oscillation is clearly observed. Advection dominates as a strong wind shear drives the mixed layer flows outward, away from the typhoon center, thus forcing upwelling from deep levels with a high upwelling velocity (> 30 m day-1. A drop in sea surface temperature (SST of more than _ is found in both observation and simulation. We attribute this significant SST drop to the influence of the slow moving typhoon, initial stratification and bathymetry-induced upwelling in the northeast of the SCS where the typhoon hovered.

    2012-01-01

    Objective To investigate the expression changes of tumor metastasis-related genes after overexpression of KAI1 in retinoblastoma Y79 cells.Methods Experimental study.Y79 cells were transfected with a lentivirus vector containing KAI1 and enhanced green fluorescent protein (EGFP) fusion gene,or a control lentivirus vector containing EGFP.Positive transfectants stably expressing high levels of KAI1 were named Y79-KAI1 and control transfectants were named Y79-KAI1/zero.These transfectants were selected by puromycin resistance and analysis with fluorescent microscopy.The expression of KAI1 mRNA and its protein among Y79,Y79-KAI1 and Y79-KAIl/zero were detected by fluorescent quantitative RT-PCR and Western blot.Differential expression of tumor metastasis-related genes in Y79-KAI1 and Y79-KAI1/zero was analyzed with human tumor metastasis PCR array.One-way ANOVA was used to analyze the differences of KAI1 mRNA and protein expression among the three groups.Results The stably transfected cell lines of Y79-KAI1 and Y79-KAI1/zero were established.The result of fluorescent quantitative real-time PCR showed that the relative quantification of mRNA level of KAI1 gene in the three kinds of cells above was 183.67 ± 21.20,1.42 ± 0.55,1.00 ± 0.00,respectively.And the expression level of KAI1 mRNA in Y79-KAI1 cells was significantly higher than those in Y79-KAI1/zero and Y79 cells (F=108.74,P =0.000).The results of Western blot showed that the expression level of the KAI1 protein in Y79-KAI1 cells was significantly higher than those in Y79-KAI1/zero and Y79 cells (F =34.36,P =0.001).Immunofluorescent staining showed that Y79 and Y79-KAI1/zero cells had no detectable KAI1 expression,while Y79-KAI1 cells expressed KAI1 in the cytoplasm surrounding the nuclei.Among the 84 tumor metastasis-related genes examined,7 genes were up-regulated more than 2 folds and 6 genes were down-regulated over 50%.Conclusion Over-expression of KAI1 may result in differential expression of tumor

  5. KAI2-and MAX2-Mediated Responses to Karrikins and Strigolactones Are Largely Independent of HY5 in Arabidopsis Seedlings

    Institute of Scientific and Technical Information of China (English)

    Mark T. Waters; Steven M. Smith

    2013-01-01

    Karrikins are butenolide compounds released from burning vegetation that stimulate seed germination and enhance seedling photomorphogenesis.Strigolactones are structurally similar plant hormones that regulate shoot and root development,and promote the germination of parasitic weed seeds.In Arabidopsis,the F-box protein MAX2 is required for responses to karrikins and strigolactones,and the α/β hydrolase KAI2 is necessary for responses to karrikins.Both MAX2 and KAI2 are essential for normal light-dependent seedling development.The bZlP transcription factor HY5 acts downstream of multiple photoreceptors and promotes photomorphogenesis,but its relationship with MAX2 and KAI2 in terms of seedling development and responses to karrikins and strigolactones is poorly defined.Here,we demonstrate that HY5 action is genetically separable from that of MAX2 and KAI2.While hy5 mutants have weak hypocotyl elongation responses to karrikins and the artificial strigolactone GR24,they have normal transcriptional responses,suggesting that HY5 is not involved in perception or action of karrikins or strigolactones.Furthermore,we show that overexpression of KAI2 is sufficient to enhance responses to both karrikins and GR24 in wild-type seedlings,and that KAI2 overexpression partially suppresses the hy5 long hypocotyl phenotype.These results suggest that KAI2 and MAX2 define a regulatory pathway that largely operates independently of HY5 to mediate seedling responses to abiotic signals such as smoke and light.

  6. Hypersensitive photic responses and intact genome-wide transcriptional control without the KaiC phosphorylation cycle in the Synechococcus circadian system.

    Cyanobacteria are unique organisms with remarkably stable circadian oscillations. These are controlled by a network architecture that comprises two regulatory factors: posttranslational oscillation (PTO) and a transcription/translation feedback loop (TTFL). The clock proteins KaiA, KaiB, and KaiC are essential for the circadian rhythm of the unicellular species Synechococcus elongatus PCC 7942. Temperature-compensated autonomous cycling of KaiC phosphorylation has been proposed as the primary oscillator mechanism that maintains the circadian clock, even in the dark, and it controls genome-wide gene expression rhythms under continuous-light conditions (LL). However, the kaiC(EE) mutation (where "EE" represents the amino acid changes Ser431Glu and Thr432Glu), where phosphorylation cycling does not occur in vivo, has a damped but clear kaiBC expression rhythm with a long period. This suggests that there must be coupling between the robust PTO and the "slave" unstable TTFL. Here, we found that the kaiC(EE) mutant strain in LL was hypersensitive to the dark acclimation required for phase shifting. Twenty-three percent of the genes in the kaiC(EE) mutant strain exhibited genome-wide transcriptional rhythms with a period of 48 h in LL. The circadian phase distribution was also conserved significantly in most of the wild-type and kaiC(EE) mutant strain cycling genes, which suggests that the output mechanism was not damaged severely even in the absence of KaiC phosphorylation cycles. These results strongly suggest that the KaiC phosphorylation cycle is not essential for generating the genome-wide rhythm under light conditions, whereas it is important for appropriate circadian timing in the light and dark.

    2007-12-01

    Dr. Richard B. Dunn, astronomer emeritus at the National Solar Observatory, died of a heart attack on September 29, 2005. He was recognized as one of the foremost experimental solar physicists. His innovative designs for telescopes and instruments led to many important discoveries in solar physics. Born in Baltimore, Maryland, in 1927 and raised in Minneapolis, Minnesota, Dick's parents were Dr. Halbert L. Dunn and Katherine Brandner. Halbert (MD, Ph.D., F.A.P.H.A.) was an physician who became Chief of the National Office of Vital Statistics, Public Health Service. He published a paper "High Level Wellness for Man and Society" that became the founding paper of the field of wellness health care. After their divorce in 1942, Katherine moved to New York and became a social worker. Dick had two older brothers who died before him, Halbert (born in 1921, who became a civil engineer) and Robert (born in 1924, who became an architect). Dick earned a BS in mechanical engineering and an MS in astronomy at the University of Minnesota. At the end of World War II he served in the United States Army in Japan. For his master's degree, Dick undertook the design and construction of a Lyot-type birefringent filter for observations of solar prominences. This early work led to his acceptance at Harvard, where Professor Donald Menzel encouraged him to continue his work with the 15-inch Cambridge telescope. In 1951 he conducted part of his doctoral thesis work at the fledgling Sacramento Peak Observatory in southern New Mexico. The observatory director, Dr. John Evans, was impressed with Dick's outstanding instrumental talents and invited him to join as one of the first scientific staff members. During his first few years at Sac Peak, Dick developed two more birefringent filter systems including one with an integrated coronagraph. With this system, he produced the best prominence and spicule observations ever obtained. Dick's career was dedicated to obtaining solar observations of the

    To explore the expressions of CD133 and CD82/KAI1 in bladder urothelial carcinoma, their association with the clinicopathological factors and their roles in vasculogenic mimicry (VM) in the tumor. The expressions of CD133 and CD82/KAI1 and VM were detected by immunohistochemistry and histochemistry in 90 specimens of bladder urothelial carcinoma and 20 specimens of normal bladder epithelium tissue. The positivity rates of CD133, CD82/KAI1 and VM in normal bladder epithelium tissue were 0, 90% and 0, showing significant differences from the rates of 65.6%, 31.1% and 31.1% in urothelial carcinoma, respectively (Page, or tumor numbers (P>0.05). CD133 expression was positively correlated with VM (P=0.487, P<0.05), and CD82/KAI1 expression was negatively correlated with VM (r=-0.452, P<0.01) and CD133 (r=-0.776, P<0.05). The expressions of CD133 and CD82/KAI1 proteins are involved in the occurrence of VM in bladder urothelial carcinoma to contribute to the invasion and relapse of bladder carcinoma.

    Aim: To evaluate KAI1/CD82 expression in Chinese patients with benign prostatic hyperplasia (BPH) and latestage carcinoma of prostate (CAP). Methods: Thirty Chinese patients with benign prostatic hyperplasia and 34 with CaP (adenocarcinoma clinical stage C and D) were analyzed by means of immunohistochemical methods. Results: The KAI1/CD82 expression in BPH tissue was all positive, which was uniformly located on the glandular cell membrane at the cell-to-cell borders, but KAI1/CD82 expression in metastasis CaP tissues was either significantly lower than that of BPH or negative, and the immunostaining pattern was not continuous. In late-stage CaP KAI1/CD82 expression was correlated inversely to the pathological grade ( P 0.05). Conclusion: The authors believe that decreased and negative KAI1/CD82 expression in late-stage CAP may be related to tumor pro-gression and metastasis, and appears to be a prognostic marker.

  15. A modified soil water based Richards equation for layered soils

    Science.gov (United States)

    Kalinka, F.; Ahrens, B.

    2010-09-01

    Most Soil-Vegetation-Atmosphere-Transfer (SVAT) models like TERRA-ML (implemented e.g. in the CCLM model (www.clm-community.eu)) use the soil moisture based Richards equation to simulate vertical water fluxes in soils, assuming a homogeneous soil type. Recently, high-resolution soil type datasets (e.g. BüK 1000, only for Germany (Federal Institute for Geosciences and Natural Resources, BGR, www.bgr.bund.de) or Harmonized World Soil Database (HWSD, version 1.1, FAO/IIASA/ISRIC/ISSCAS/JRC, March 2009)) have been developed. Deficiencies in the numerical solution of the soil moisture based Richards equation may occur if inhomogeneous soil type data is implemented, because there are possibly discontinuities in soil moisture due to various soil type characteristics. One way to fix this problem is to use the potential based Richards equation, but this may lead to problems in conservation of mass. This presentation will suggest a possible numerical solution of the soil moisture based Richards equation for inhomogeneous soils. The basic idea is to subtract the equilibrium state of it from soil moisture fluxes. This should reduce discontinuities because each soil layer aspires the equilibrium state and therefore differences might be of the same order. First sensitivity studies have been done for the Main river basin, Germany.

    Objective To investigate the expression and significanceof CD82/KAI1in bladder urotheli-alcancer tissues. Methods Parafflin-embeded specimens of 50 cases of bladder urothelialcancer and 5 normal tissues near the cancer, which were all filed in full pathological and clinical data, were collected from the pathology department of the Renmin Hospital of Wuhan University between 2006 and 2010. The expression of CD82/KAI1 was detected by immunohistochemical S-P method. Quantitative analysis of CD82/ KAI1 was conducted by a high-definitionpathological graphics context report system (HPIAS-1000). Oneway analysis of variance and SNK(q) tests were usedto analyse the mean density and the positive area rate of the immunohistochemical results. All data were processed by SPSS13. 0. Results The expression of CD82/KAI1 was higher in normal paracancerous tissues, than in bladder urothelialcancer tissues, with a statistically significant difference (P<0. 05). Conclusion The anomalous expression of CD82/KAI1 in bladder urothelialcancer tissues may play an important role in the occurrence and development of bladder urothelial cancer.%目的 探讨膀胱尿路上皮癌中CD82/KAI1的表达及临床意义.方法 收集武汉大学人民医院病理科2006-2010年有完整临床和病理资料的膀胱尿路上皮癌存档蜡块50例和5例癌旁组织,采用免疫组织化学S-P法检测50例膀胱尿路上皮癌和5例癌旁组织中CD82/KAI1的表达水平.采用HPIAS-1000 高清晰度彩色病理图文报告管理系统,对CD82/KAI1的表达进行定量分析,并用SPSS13.0 软件对各组免疫组织化学反应阳性颗粒的平均光密度、阳性面积率做单因素方差分析和SNK(q)检验.结果 CD82/KAI1在膀胱尿路上皮癌中呈低表达,癌旁组织中呈高表达.膀胱尿路上皮癌与癌旁组织相比,差异有显著性 (P<0.05).结论 CD82/KAI1在膀胱尿路上皮癌中的表达异常可能在膀胱尿路上皮癌的发生和发展中发挥了重要作用.

    In 1965 the Nobel Foundation honored Sin-Itiro Tomonaga, Julian Schwinger, and Richard Feynman for their fundamental work in quantum electrodynamics and the consequences for the physics of elementary particles. In contrast to both of his colleagues only Richard Feynman appeared as a genius before the public. In his autobiographies he managed to connect his behavior, which contradicted several social and scientific norms, with the American myth of the "practical man". This connection led to the image of a common American with extraordinary scientific abilities and contributed extensively to enhance the image of Feynman as genius in the public opinion. Is this image resulting from Feynman's autobiographies in accordance with historical facts? This question is the starting point for a deeper historical analysis that tries to put Feynman and his actions back into historical context. The image of a "genius" appears then as a construct resulting from the public reception of brilliant scientific research.

    An explosion on the Sun in 1859, serendipitously witnessed by amateur astronomer Richard Carrington, plunged telegraphic communications into chaos and bathed two thirds of the Earth's skies in aurorae. Explaining what happened to the Sun and how it could affect Earth, 93 million miles away, helped change the direction of astronomy. From being concerned principally with charting the stars to aid navigation, astronomers became increasingly concerned with what the celestial objects were, how they behaved and how they might affect life on Earth.

    Full Text Available Circadian (daily rhythms are a fundamental and ubiquitous property of eukaryotic organisms. However, cyanobacteria are the only prokaryotic group for which bona fide circadian properties have been persuasively documented, even though homologs of the cyanobacterial kaiABC central clock genes are distributed widely among Eubacteria and Archaea. We report the purple non-sulfur bacterium Rhodopseudomonas palustris (that harbors homologs of kaiB and kaiC only poorly sustains rhythmicity in constant conditions-a defining characteristic of circadian rhythms. Moreover, the biochemical characteristics of the Rhodopseudomonas homolog of the KaiC protein in vivo and in vitro are different from those of cyanobacterial KaiC. Nevertheless, R. palustris cells exhibit adaptive kaiC-dependent growth enhancement in 24-h cyclic environments, but not under non-natural constant conditions. Therefore, our data indicate that Rhodopseudomonas does not have a classical circadian rhythm, but a novel timekeeping mechanism that does not sustain itself in constant conditions. These results question the adaptive value of self-sustained oscillatory capability for daily timekeepers and establish new criteria for circadian-like systems that are based on adaptive properties (i.e., fitness enhancement in rhythmic environments, rather than upon observations of persisting rhythms in constant conditions. We propose that the Rhodopseudomonas system is a "proto" circadian timekeeper, as in an ancestral system that is based on KaiC and KaiB proteins and includes some, but not necessarily all, of the canonical properties of circadian clocks. These data indicate reasonable intermediate steps by which bona fide circadian systems evolved in simple organisms.

    Invasion of trophoblasts into maternal uterine tissue is essential for establishing mature feto-maternal circulation. The trophoblast invasion associated with placentation is similar to tumor invasion. In this study, we investigated the role of KAI1, an anti-metastasis factor, at the maternal-fetal interface during placentation. Mouse embryos were obtained from gestational days 5.5 (E5.5) to E13.5. Immunohistochemical analysis revealed that KAI1 was expressed on decidual cells around the track made when a fertilized ovum invaded the endometrium, at days E5.5 and E7.5, and on trophoblast giant cells, along the central maternal artery of the placenta at E9.5. KAI1 in trophoblast giant cells was increased at E11.5, and then decreased at E13.5. Furthermore, KAI1 was upregulated during the forskolinmediated trophoblastic differentiation of BeWo cells. Collectively, these results indicate that KAI1 is differentially expressed in decidual cells and trophoblasts at the maternal-fetal interface, suggesting that KAI1 prevents trophoblast invasion during placentation.

CERN scientists probe ever-deeper levels of matter and their interactions, but can we say that the patterns they see are truly fundamental? Does the universe obey the same laws throughout? Since mathematical constructions can be true in the absence of any relation to the physical world, is mathematics more fundamental than physics?

  8. Development and assessment of an efficient numerical solution of the richard's equation including root extraction by plants

    Varado, N.; Braud, I.; Ross, P. J.

    2003-04-01

    A new numerical method for solving the 1D Richard's equation has been proposed by P. Ross (Agronomy J., 2003, in press). The Kirchhoff transform or degree of saturation is used instead of the classical matrix potential. The solution can be used both for saturated or non saturated soils. Hydraulic properties are described using the Brooks and Corey model. The soil is discretized into layers. Their thickness can be larger than in classical matrix potential methods, due to the use of a time and space varying weighing procedure for the calculation of fluxes between layers. This allows the use of a non iterative procedure, ensuring a very fast numerical solution. Extensive tests showed that the new method was very accurate for bare soils. The next step was the addition of a root extraction module in order to account for plant transpiration. Two root water uptake modules with compensation mechanisms in case of water stress were chosen from the literature. They express the transpiration source term in the Richards equation as a linear function of a potential transpiration and take into account water stress and its effects on plant transpiration. These modules were proposed first by Lai and Katul (Adv. Water Resour., 2000) and Li et al. (J. Hydrol., 2001). The new version of the model has been tested in a systematic way with several soils characteristics, climate forcings, and evapotranspiration calculation. Like the tests without vegetation, the SiSPAT (Simple Soil Plant Atmosphere Transfer) model was considered as a reference after implementation of the same roots modules. The numerical solution was also tested using a soybean data set. The variations and the cumulative values like drainage, water content, real transpiration and real evapotranspiration were in a good agreement with the SiSPAT modelling, with a relative error of less than 3%. The error on soil evaporation remained important (about 20%) on low cumulative values (less than 20mm), i.e. when LAI was close to

One of the rules for validating a move in this game consists in taking for granted the distinction between the public and the private spheres. Richard Rorty thought that democratic liberalism did not need any foundation beyond the way to play it; its only criteria would be the game's practices, according an utopia which would allow us to make more movements in the game. That is, democratic liberalism does not require foundations, but just practices for achieving a social hioe inspired on freedom and pluralism. This kind of utopia, based upon the non-cruelty principle, would make possible an inclusive society where everyone would have a place for their own private vocabulary. In this way, Rorty would have linked freedom and solidarity. However, this language-game reveals the paradox of the link which implies the meaning of the public shere. Herein, freedom is not a sufficient condition of solidarity; hence, there is no place for social inclusion in Rorty's language game.

    Richard III was the last king of England to die in battle, but how he died is unknown. On Sept 4, 2012, a skeleton was excavated in Leicester that was identified as Richard. We investigated the trauma to the skeleton with modern forensic techniques, such as conventional CT and micro-CT scanning, to characterise the injuries and establish the probable cause of death. We assessed age and sex through direct analysis of the skeleton and from CT images. All bones were examined under direct light and multi-spectral illumination. We then scanned the skeleton with whole-body post-mortem CT. We subsequently examined bones with identified injuries with micro-CT. We deemed that trauma was perimortem when we recorded no evidence of healing and when breakage characteristics were typical of fresh bone. We used previous data to identify the weapons responsible for the recorded injuries. The skeleton was that of an adult man with a gracile build and severe scoliosis of the thoracic spine. Standard anthropological age estimation techniques based on dry bone analysis gave an age range between 20s and 30s. Standard post-mortem CT methods were used to assess rib end morphology, auricular surfaces, pubic symphyseal face, and cranial sutures, to produce a multifactorial narrower age range estimation of 30-34 years. We identified nine perimortem injuries to the skull and two to the postcranial skeleton. We identified no healed injuries. The injuries were consistent with those created by weapons from the later medieval period. We could not identify the specific order of the injuries, because they were all distinct, with no overlapping wounds. Three of the injuries-two to the inferior cranium and one to the pelvis-could have been fatal. The wounds to the skull suggest that Richard was not wearing a helmet, although the absence of defensive wounds on his arms and hands suggests he was still otherwise armoured. Therefore, the potentially fatal pelvis injury was probably received post mortem

    2007-01-01

    Mitte des 20. Jahrhunderts entwickelten David Bohm und Richard Feynman zwei grundlegend verschiedene Ansätze der moderne Quantenmechanik: Bohm eine realistische Deutung mit Hilfe verborgener Parameter und Feynman den Pfadintegralformalismus. Dies ist umso bemerkenswerter, weil beide Physiker von ähnlichen Voraussetzungen ausgingen und aus ähnlichen Zusammenhängen stammten. Durch ihren vergleichenden Ansatz bietet diese Studie mehr als einen Beitrag zur Geschichte der Quantentheorie. Mit der Frage nach den sozialen und kulturellen Bedingungen der Theoriebildung ist sie darüberhinaus von wissenschaftssoziologischem und wissenschaftstheoretischem Interesse. Die anfangs ähnliche und später unterschiedliche Einbindung der beiden Wissenschaftler in die Scientific Community erlaubt es überdies zu untersuchen, welchen Anpassungsdruck die jeweilige Gruppe auf den individuellen Wissenschaftler und die Kernbestandteile seiner Forschungen ausübt und welche neuen Freiheitsgrade für die Theoriebildung entstehen, ...

Neste breve artigo, traço um resumo dessa crítica à teoria de Hare, em especial,da chamada “Lei de Hume”, a qual Sen preferiu apropriadamente intitular “Regra de Hare”. Pretendomostrar como esse tipo peculiar de “existencialismo” nos conduz, ainda que sob o possível protesto deHare e seus seguidores, a conclusões subjetivistas e relativistas sobre a moralidade.

  16. Richard III, Barer-Stoddart and the Daughter of Time.

    2008-02-01

    "Truth is the daughter of Time," said mystery writer Josephine Tey. This point, illustrated in her rehabilitation of the "villainous" King Richard III, is equally apt for a reconsideration of the 1991 Barer-Stoddart report on medical personnel. Canadian physicians have reviled these authors for "creating" a physician shortage by encouraging provincial cuts to medical school enrolment. Yet, data pre- and post-1991 are quite clear: their report did not and could not have had this effect. The physician-to-population ratio has been stable since 1989. Average physician hours of work have fallen, but per capita expenditures on physicians' services (inflation-adjusted) are rising rapidly. A flood of physicians from the major expansion of enrolments now in place threatens serious fiscal trouble over the next two decades, and is likely to pre-empt any significant system reform.

  17. British Missionary Timothy Richard and Chinese Modern Education

    British missionary Timothy Richard came to China, actuated by preaching the Gospel andexpanding the sphere of Christian influence. Considering some complex reasons for history, civilization,ideology and custom etc, he paid attention to secular education as well as doing missionary work to attainhis Christian goal. He laid much stress on the function of education, so he proposed Chinese governmentshould set up Educational Department. In the late Qing Dynasty, he participated in the organization andmanagement of Shanxi Imperial University. Under the circumstances of modern times of China, when it wasin the grip of national crisis, and the contradictory between China and foreign countries was acute andcomplicated, all the work he had done exerted objective influences in many aspects. While it reflected thestrong semi-colonial character in modernization of Chinese education, it had some positive effect as well.

    Full Text Available Richard Rothwell was an Irish portraitist who was successful in Londonin the late 1820s. Despite this achievement he felt he had to leave Londonto acquaint himself with the Italian Masters and see what trends were indemand in Rome in the early 1830s. This chapter analyses how the Italianexperience affected his creativity and examines the reasons for his proclivitytowards genre and landscape over portraits in works produced up tohis death in 1868. Attention is paid to the Rothwell holdings in the NationalGallery of Ireland and the National Museum of Northern Ireland.The reasons for the negative reaction to Rothwell’s “Italian” art on his returnto England are examined while it is also argued that he may haveretained his initial success as a portrait painter had he never gone to Italy.

    Rice (Oryza sativa L.) is the main food for people in Laos, where it has been grown and eaten since prehistory. Diverse landraces are grown in Laos. 'Khao Kai Noi', a landrace favored for its eating quality, is held in the nationwide collection of traditional landraces in the Lao national genebank. Genetic diversity is crucial for sustainable use of genetic resources and conservation. To investigate the genetic diversity of 'Khao Kai Noi' for conservation, we genotyped 70 accessions by using 23 polymorphic simple sequence repeat markers. The markers generated 2 to 17 alleles (132 in total), with an average of 5.7 per locus. The total expected heterozygosity over all 'Khao Kai Noi' accessions was 0.271. Genetic variation was largest among accessions and smallest within accessions. Khao Kai Noi accessions were classified into three different genetic backgrounds, but there was unclear association between the three inferred population and name subgroups and geographical distribution. Most of the accessions were clustered with temperate japonica and showed genetic relatedness to rice from neighboring provinces of Vietnam, suggesting a Vietnamese origin. The results of this study will contribute to the conservation, core collection and future breeding of the Khao Kai Noi population.

    The theoretical physicist Philipp Frank (1884 1966) and the applied mathematician Richard von Mises (1883 1953) both received their university education in Vienna shortly after 1900 and became friends at the latest during the Great War.They were attached to the Vienna Circle of Logical Positivists and wrote an influential two-part work on the differential and integral equations of mechanics and physics, the Frank-Mises, of 1925 and 1927, with its second edition following in 1930 and 1935.This work originated in the lectures that the mathematician Bernhard Riemann (1826 1866) delivered on partial differential equations and their applications to physical questions at the University of Göttingen between 1854 and 1862, which were edited and published posthumously in1869 by the physicist Karl Hattendorff (1834 1882).The immediate precursor of the Frank-Mises, however, was the extensive revision of Hattendorff’s edition of Riemann’s lectures that the mathematician Heinrich Weber (1842 1913) published in two volumes, the Riemann-Weber, of 1900 and 1901, with its second edition following in 1910 and 1912. I trace this historical lineage, explore the nature and contents of the Frank-Mises, and discuss its complementary relationship to the first volume of the text that the mathematicians Richard Courant (1888 1972) and David Hilbert (1862 1943) published on the methods of mathematical physics in 1924, the Courant-Hilbert,which, when it and its second volume of 1937 were translated into English and extensively revised in 1953 and 1961, eclipsed the classic Frank-Mises.

    2008-01-01

    Full Text Available El concepto de lo público en Richard Rorty, heredero de la tradición liberal, admite ser tratado como parte de un juego del lenguaje denominado liberalismo democrático. En ese sentido, una de las reglas de este juego para saber si una jugada es válida consiste en asumir la distinción entre esfera pública y privada. Richard Rorty pensó que este juego no requería fundamentación más allá de la forma de jugarlo, que el criterio en que se apoyaría estaba en las prácticas que tienen lugar dentro del mismo con arreglo a sostener una utopía que permitiera hacer cada vez más jugadas. Esto es, el liberalismo democrático no requería basarse en algo más allá de las prácticas conducentes a lograr una esperanza social alentada por la libertad en defensa del pluralismo. Su utopía liberal, guiada por el principio de la no-crueldad, haría posible una sociedad inclusiva en la que todos tuvieran espacio para su léxico privado. De este modo, Rorty habría vinculado libertad y solidaridad, pero su juego del lenguaje permite advertir la paradoja del vínculo que implicaría el sentido de lo público. Aquí, la libertad no es condición suficiente de la solidaridad, de modo que la inclusión social no tiene cabida en su juego del lenguaje.

    Full Text Available Quando consideramos a extensão da obra dramática de Richard Wagner, não causa estranheza que seus textos teóricos sejam praticamente desconhecidos. No entanto, um de seus escritos, intitulado Beethoven, influenciou decisivamente a elaboração de um livro famoso, hoje considerado um capítulo importante da história da estética, O nascimento da tragédia. Este artigo pretende analisar este escrito de Wagner na intenção de desvendar o que pode ter sido tão determinante na leitura que Nietzsche fez dele, e que o levou ao ponto de citá-lo de modo efusivo no primeiro prefácio da sua obra de estréia, dedicado àquele que, até então, era seu grande mestre e amigo e, como veremos, uma influência não só musical, mas também teórica.If we consider the magnitude of the Richard Wagner's dramatic work, it will be not strange to realize that his theoretical texts are almost entirely unknown. However, one of his writings, entitled Beethoven, exercised decisive influence upon the composition of The birth of tragedy, a famous book regarded nowadays as an essential moment of the history of aesthetics. The purpose of this paper is to examine this Wagner's writing aiming to unriddle which determinative motive brought Nietzsche to mention it enthusiastically in the original foreword of his first work, dedicated to whom which, until that moment, were his master and friend and exercised upon him an influence both musical and theoretical.

    The metastasis suppressor KAI1/CD82 has been implicated in various cellular processes; however, its function in development is not fully understood. Here, we generated and characterized mutants of Tsp66E and Tsp74F, which are Drosophila homologues of KAI1/CD82 and Tspan11, respectively. These mutants exhibited egg elongation defects along with disturbed integrin localization and actin polarity. Moreover, the defects were enhanced by mutation of inflated, an αPS2 integrin gene. Mutant ovaries had elevated αPS2 integrin levels and reduced endocytic trafficking. These results suggest that Drosophila KAI1/CD82 affects the polarized localization and the level of integrin, which may contribute to epithelial cell polarity.

    In contrast to Synechococcus elongatus PCC 7942, few data exist on the timing mechanism of the widely used cyanobacterium Synechocystis sp. PCC 6803. The standard kaiAB1C1 operon present in this organism was shown to encode a functional KaiC protein that interacted with KaiA, similar to the S. elongatus PCC 7942 clock. Inactivation of this operon in Synechocystis sp. PCC 6803 resulted in a mutant with a strong growth defect when grown under light-dark cycles, which was even more pronounced when glucose was added to the growth medium. In addition, mutants showed a bleaching phenotype. No effects were detected in mutant cells grown under constant light. Microarray experiments performed with cells grown for 1 day under a light-dark cycle revealed many differentially regulated genes with known functions in the ΔkaiABC mutant in comparison with the WT. We identified the genes encoding the cyanobacterial phytochrome Cph1 and the light-repressed protein LrtA as well as several hypothetical ORFs with a complete inverse behaviour in the light cycle. These transcripts showed a stronger accumulation in the light but a weaker accumulation in the dark in ΔkaiABC cells in comparison with the WT. In general, we found a considerable overlap with microarray data obtained for hik31 and sigE mutants. These genes are known to be important regulators of cell metabolism in the dark. Strikingly, deletion of the ΔkaiABC operon led to a much stronger phenotype under light-dark cycles in Synechocystis sp. PCC 6803 than in Synechococcus sp. PCC 7942. © 2014 The Authors.

    2017-03-01

    Full Text Available Whatever else it takes to drive a taxi, it takes trust. Day after day, the driver has to decide whether the other is or is not trustworthy. I take the taxi as a test case to analyze and assess Richard Kearney’s diacritical hermeneutics of the other. I argue that Kearney functionalizes the concept of transcendence in order to connect the transcendence of the finite other to the transcendence of the infinite other. However, in his central critique of the deconstructionists following Jacques Derrida, Kearney counters his connection. While Kearney’s critique of Derrida’s account of absolute alterity is correct and compelling, I argue that Derrida’s critique of a distinction between the trustworthy other and the non-trustworthy other might be more crucial than Kearney contends. Insisting on openness to the other’s otherness, Derrida provokes any hermeneutic of the other to trust in transcendence. The taxi is taken as a test to illustrate the implications which diacritical and deconstructive drivers might have for evaluating the entanglement of ethics and eschatology—inside and outside the taxi.

    Howard Williams

    2013-04-01

    Full Text Available This paper investigates the origins of British Anglo-Saxon archaeology by focusing on the work of one early Victorian archaeologist: Richard Cornwallis Neville. The seemingly descriptive and parochial nature of Neville’s archaeological pursuits, together with the attention he afforded to Romano-British remains, has impeded due recognition, and critical scrutiny, of his contributions to the development of early Medieval burial archaeology. Using his archaeological publications as source material, I will show how Neville’s interpretations of Saxon graves were a form of memory work, defining his personal, familial and martial identity in relation to the landscape and locality of his aristocratic home at Audley End, near Saffron Walden, Essex. Subsequently, I argue that Neville’s prehistoric and Romano-British discoveries reveal his repeated concern with the end of Roman Britain and its barbarian successors. Finally, embodied within Neville’s descriptions of early Medieval graves and their location we can identify a pervasive Anglo-Saxonism. Together these strands of argument combine to reveal how, for Neville, Saxon graves constituted a hitherto unwritten first chapter of English history that could be elucidated through material culture and landscape.

  16. Novelty, Pattern, and Force in Richard Powers’s 'Orfeo'

    Directory of Open Access Journals (Sweden)

    Kathryn Hume

    2017-01-01

    Full Text Available Richard Powers’s 'Orfeo' pits novelty against familiar pattern, and explores the destructive effects of forcing something new to fit known patterns in art, science, and politics. The protagonist’s dedication to writing truly new music wrecks his marriage and damages his personal life. His tinkering with novelty in bacterial genes will apparently get him killed by the police. Powers has argued in 'The Gold Bug Variations' that the point of science is wonder, not control. Powers embodies this tension between novelty and known pattern by imposing the Orpheus myth on a composer for whom traditional patterns are anathema. Further, by embedding a radical political protest within a well-known myth, Powers demonstrates in his own writing the presentation of the new within recognizable older patterns, the tactic that protagonist Peter Els could have tried with his music if he had hoped to develop an audience. On the political level, Powers equates oppressive police power with forcing unusual people to fit a narrow range of behavior and belief patterns.

    2010-02-01

    Full Text Available Le roman de Richard Powers, Operation Wandering Soul (1993, présente le lien subtil qui associe un mondialisme déjà usé et vieillissant à l’enfant perçu comme catégorie dominante. Comme les faces serpentines d’un ruban de Möbius lové autour de l’illimité et de l’intemporel, le texte, tendu entre ses deux infinis – l’univers et l’enfant – révise la portée, la conception, la structure et le style du genre romanesque. Délaissant Aristote pour Einstein, Operation Wandering Soul se place sur le terrain de la cosmologie. Le récit, qui rassemble la kyrielle des grands ralliements juvéniles et leurs vains pèlerinages, concentre l’espace-temps dans une présentation qui évoque la « somme des histoires » de Richard Feynman. La contraction de l’espace-temps opérée par le roman ne fait pas de celui-ci un hymne simpliste au global (catégorie déjà aussi datée que celle des malheureux vétérans du Vietnam, mais capte au contraire la conscience grandissante d’une existence sans origine qui s’étend à perte de vue au-delà de ses coordonnées supposées. Le roman s’enroule sur lui-même tout en s’épanchant au dehors, boucle ses cadres et ses détours tout en desserrant leur emprise. Il fait tourner la roue de ses récits comme des planètes en rotation, la ronde d’un système solaire, le tourbillon d’une galaxie. La conscience que présente Operation Wandering Soul ne se résume donc pas au seul point de vue de l’âme errante qu’est le personnage de Kraft, mais consiste en la somme de tous les temps et de tous les lieux, de leurs strates accumulées comme une conscience en acte, complexe et tissée de réseaux, qui n’appartient à personne et est partagée par tous. Cette accumulation organise le jeu des perspectives multiples qui instaurent l’acte de lecture et sont instaurées par lui.

    2008-11-01

    This paper concentrates on two aspects of the work of Leipzig brain researcher Richard Arwed Pfeifer (1877-1957). It has been little known that Pfeifer, like Prinzhorn, collected paintings by his schizophrenic patients. In works about these paintings, he tried to decipher their specific attraction and the possibility of differentiating artworks of sane artists from those of insane ones. From experimental research he concluded that the "demonic element" was of utmost importance, which however could temporarily be brought about by sane artists too. Trained in medicine and psychology by Wundt, Flechsig, and Niessl von Mayendorf, Pfeifer was appointed as the first associate professor of brain research in Germany in 1927. Until now he has been appreciated for reestablishing the angioarchitecture of the brain, mainly due to his works on the distribution of capillaries in the brain achieved by a particular method of injection which he developed. Moreover he contributed new findings on the interrelations of the capillaries and thus finally disproved the existence of so-called terminal arteries of Cohnheim.

  19. Shakespeare's Richard III and Macbeth: A Foucauldian Reading

    2013-01-01

    Full Text Available Reading for signs of power and its function in the world of Shakespeare's plays under the light of Michel Foucault reveals to be in stark contrast from traditional notions of the operation of power. An important Renaissance critic, E. M. Tillyard, has declared that Shakespeare's plays reflect faithfully the Elizabethan world order, remaining loyal to the hierarchical concept of power and its function in Elizabethan England. Such readings engage mainly with the protagonist of the plays, revealing the various aspects in which the world of the play moves toward order and harmony. A Foucauldian reading of the plays however is able to unveil more than merely a one-dimensional reflection of power structures of the society of the time. By focusing on Foucault's notion of power relations at work in the society and also his emphasis on the marginalized aspects, this study aims to reveal how power relations in the two plays under consideration, Richard III and Macbeth, can reveal versatile experiences.

  20. Perception of Leitmotives in Richard Wagner's Der Ring des Nibelungen.

    Baker, David J; Müllensiefen, Daniel

    2017-01-01

    The music of Richard Wagner tends to generate very diverse judgments indicative of the complex relationship between listeners and the sophisticated musical structures in Wagner's music. This paper presents findings from two listening experiments using the music from Wagner's Der Ring des Nibelungen that explores musical as well as individual listener parameters to better understand how listeners are able to hear leitmotives, a compositional device closely associated with Wagner's music. Results confirm findings from a previous experiment showing that specific expertise with Wagner's music can account for a greater portion of the variance in an individual's ability to recognize and remember musical material compared to measures of generic musical training. Results also explore how acoustical distance of the leitmotives affects memory recognition using a chroma similarity measure. In addition, we show how characteristics of the compositional structure of the leitmotives contributes to their salience and memorability. A final model is then presented that accounts for the aforementioned individual differences factors, as well as parameters of musical surface and structure. Our results suggest that that future work in music perception may consider both individual differences variables beyond musical training, as well as symbolic features and audio commonly used in music information retrieval in order to build robust models of musical perception and cognition.

    Full Text Available El planteamiento teórico de Richard Rorty acerca de las culturas liberales como comunidades conscientes de su contingencia histórica, pero también capaces de unirse en un proyecto público de solidaridad humana, constituye una importante propuesta que enriquece la discusión política en la actualidad. Su postura democrática antifundamentalista, su intento de reconciliar lo público con lo privado no mediante la  filosofía, sino a través de la literatura, así como su ironismo para evadir o rechazar debates tradicionales entre los filósofos, lo convierten en un pensador polémico e interesante.

    Richard Floyd Darsie, Jr. (1915-2014) is the 2015 American Mosquito Control Association Memorial Lecture Honoree. He was one of the greatest mosquito taxonomists of the 20th century and died peacefully on April 10, 2014, in Grove City, PA, at the age of 99 after a professional career that spanned eight decades. Dick's broad areas of interest and training made him a versatile scientist, teacher, and researcher. His intense interest in adult and immature mosquito morphology and taxonomy, as well as mosquito distribution and bionomics, started early in his career at two early academic postings: Franklin and Marshall College (1949-54) and the University of Delaware (1954-62). Dick would take his mosquito interests with him to postings and research projects around the world: Nepal, the Philippines, Atlanta, El Salvador, Guatemala, Fort Collins, South Carolina, Argentina, and Florida. His travels and studies would make him an international expert on mosquito taxonomy. Dick's legacy lives on in the hundreds of students from across the globe who learned mosquito identification skills from this world-renowned mosquito taxonomist. All will proudly profess that, "I learned mosquito identification from Dr. Darsie." And that is all that is needed to prove one's credentials in the field, learning the art from the best there is.

  3. Perception of Leitmotives in Richard Wagner's Der Ring des Nibelungen

    2017-05-01

    Full Text Available The music of Richard Wagner tends to generate very diverse judgments indicative of the complex relationship between listeners and the sophisticated musical structures in Wagner's music. This paper presents findings from two listening experiments using the music from Wagner's Der Ring des Nibelungen that explores musical as well as individual listener parameters to better understand how listeners are able to hear leitmotives, a compositional device closely associated with Wagner's music. Results confirm findings from a previous experiment showing that specific expertise with Wagner's music can account for a greater portion of the variance in an individual's ability to recognize and remember musical material compared to measures of generic musical training. Results also explore how acoustical distance of the leitmotives affects memory recognition using a chroma similarity measure. In addition, we show how characteristics of the compositional structure of the leitmotives contributes to their salience and memorability. A final model is then presented that accounts for the aforementioned individual differences factors, as well as parameters of musical surface and structure. Our results suggest that that future work in music perception may consider both individual differences variables beyond musical training, as well as symbolic features and audio commonly used in music information retrieval in order to build robust models of musical perception and cognition.

  4. Failed Mothers, Monster Sons. Reading Shakespeare’S Richard Iii as a Fairy Tale

    2014-03-01

    Full Text Available The paper looks at Shakespeare’s historical play Richard III and its fairy tale-like character given by the configuration of the main character as an arch-villain and the presence of motifs and patterns typically associated with the fairy tale genre. More specifically, it considers the mother-son relationship between the Duchess of York and Richard in the light of the motif of monstrous birth. It is not a coincidence that the emergence of such motifs coincides with the historical contexts of the early modern period. Reading Richard III in this key is related to the revisionist approach to chronicle plays.

  5. The Crumbling Two-Story Architecture of Richard Powers’ Fictions

    Full Text Available L’alternance de deux récits différents au sein d’une même narration constitue l’une des marques les plus saillantes de la technique narrative de Richard Powers. Cependant, les rapports qu’entretiennent ces deux récits varient sensiblement d’un roman à l’autre. Ils peuvent, d’un point de vue diégétique, reposer sur un même personnage, comme dans Galatea 2.2, ou sur la rencontre ponctuelle de divers protagonistes, comme dans The Echo Maker. Il arrive aussi qu’ils explorent un enchaînement présumé de cause à effet, comme dans Gain. Plus radicalement, dans Plowing the Dark, les deux récits paraissent tisser des liens essentiellement métaphoriques qui excluent plus ou moins toute idée de métonymie. Sur le plan de la signification, les deux récits semblent parfois former une unité lorsque combinaisons, parallèles et oppositions font se lever entre eux des rapports dialectiques. Ce travail met en évidence, dans plusieurs romans de Powers, les diverses permutations de cette structure à double récit et tente de cerner ce qui pourrait en constituer le « reste », élément irréductible à toute unité thématique ou artistique. Si un tel reste existe, quel sens pourrait-il alors revêtir ?A prominent characteristic of Richard Powers’ technique is that his novels generally proceed by the alternating narration of two different stories. The relations of one story to another vary quite widely, however. On the diegetic level, the two may have a common protagonist, as in Galatea 2.2; or they may concern the different but circumstantially intersecting lives of disparate figures, as in The Echo Maker; or they may explore a possible chain of cause and effect, as in Gain. Most radically, in Plowing the Dark, their relation seems to be more or less purely metaphoric, with little or no metonymic connection at all. On the level of meaning, the two stories may seem to form unities by operating in conjunction or parallel or

  6. Solving Richards Equation for snow improves snowpack meltwater runoff estimations

    Full Text Available The runoff from the snow cover during spring snow melt or rain-on-snow events is an important factor in the hydrological cycle. In this study, water transport schemes for a 1-dimensional physical based snowpack model are compared to 14 yr of lysimeter measurements at a high alpine site. The schemes include a simple bucket-type approach, an approximation of Richards Equation (RE, and the full RE. The results show that daily sums of runoff are strongly related to a positive energy balance of the snow cover and therefore, all water transport schemes show very similar performance in terms of Nash–Sutcliffe efficiency (NSE coefficients (around 0.59 and r2 values (around 0.77. Timing of the arrival of meltwater in spring at the bottom of the snowpack showed differences between the schemes, where especially in the bucket-type and approximated RE approach, meltwater release is slower than in the measurements. Overall, solving RE for the snow cover yields the best agreement between modelled and measured runoff. On sub-daily time scales, the water transport schemes behave very differently. Also here, solving RE provides the highest agreement between modelled and measured runoff in terms of NSE coefficient (0.48, where other water transport schemes loose any predictive power. This appears to be mainly due to bad timing of meltwater release during the day. Accordingly, solving RE for the snow cover improves several aspects of modelling snow cover runoff. The additional computational cost was found to be in the order of a factor of 1.5.

    Full Text Available The objective of this study was to introduce application of the Richards equation on modelling and prediction of stand diameter distribution. The long-term repeated measurement data sets, consisted of 309 diameter frequency distributions from Chinese fir (Cunninghamia lanceolata plantations in the southern China, were used. Also, 150 stands were used as fitting data, the other 159 stands were used for testing. Nonlinear regression method (NRM or maximum likelihood estimates method (MLEM were applied to estimate the parameters of models, and the parameter prediction method (PPM and parameter recovery method (PRM were used to predict the diameter distributions of unknown stands. Four main conclusions were obtained: (1 R distribution presented a more accurate simulation than three-parametric Weibull function; (2 the parameters p, q and r of R distribution proved to be its scale, location and shape parameters, and have a deep relationship with stand characteristics, which means the parameters of R distribution have good theoretical interpretation; (3 the ordinate of inflection point of R distribution has significant relativity with its skewness and kurtosis, and the fitted main distribution range for the cumulative diameter distribution of Chinese fir plantations was 0.4∼0.6; (4 the goodness-of-fit test showed diameter distributions of unknown stands can be well estimated by applying R distribution based on PRM or the combination of PPM and PRM under the condition that only quadratic mean DBH or plus stand age are known, and the non-rejection rates were near 80%, which are higher than the 72.33% non-rejection rate of three-parametric Weibull function based on the combination of PPM and PRM.

  9. Desire and the Other in Richard Yates's Revolutionary Road

    2011-06-01

    Full Text Available Richard Yates’s novel Revolutionary Road did not receive much academic attention despite the fact that it is an exceptionally refined and capturing piece of fiction. It was critically acclaimed following its publication in 1961, nominated for the National Book Award in 1962 and then forgotten. Not surprisingly, the novel was “rediscovered” once a movie adaptation was made in 2008. Revolutionary Road is typically read – quite expectedly – as a story of suburban malaise and a critique of the American (suburban life in the 1950s. However, in an interview, published in Ploughshares in 1972, Yates stated that although he intended the novel to be an indictment of American life in the 1950s because of a general lust for conformity (DeWitt and Clark 66, he never planned the novel to be anti-suburban in any way. On the contrary, he hoped to make it implicit in the text that he is writing about a particular couple, the Wheelers, and what turns out to be specifically “their delusion, their problem” (DeWitt and Clark 66. In that sense, the novel should be read as a psychological exploration of the universal issues of human desire and the relationship of the individual to the pre-established (social system in which he or she lives. Consequently, it becomes clear that Yates’s novel hardly represents an indictment of a way of life, but quite the opposite: an indictment of the individual unable to adapt to the demands of the Other. In Lacanian terms, Revolutionary Road is a story about the unattainable desire to create one’s identity regardless or in spite of the socially constructed Symbolic order.

    It is with a great deal of both happiness and sadness that I have to announce that we are losing one of the real strengths of the Journal of Physics: Condensed Matter (JPCM). Dr Richard Palmer, our Senior Publisher, announced his retirement, and this issue marks the first without his involvement. Of course, we are happy that he will get to enjoy his retirement, but we are sad to lose such a valuable member of our team. Richard first started work at IOP Publishing in March 1971 as an Editorial Assistant with Journal of Physics B: Atomic and Molecular Physics. After a few months, he transferred to Journal of Physics C: Solid State Physics. During his first year, he was sent on a residential publishing training course and asked to sign an undertaking to stay at IOP Publishing for at least two years. Although Richard refused to sign, as he did not want to commit himself, he has remained with the journal since then. The following year, the Assistant Editor of Journal of Physics C: Solid State Physics, Malcolm Haines, walked out without notice in order to work on his family vineyard in France, and Richard stepped into the breach. In those days, external editors had a much more hands-on role in IOP Publishing and he had to travel to Harwell to be interviewed by Alan Lidiard, the Honorary Editor of Journal of Physics C: Solid State Physics, before being given the job of Assistant Editor permanently. I am told that in those days the job consisted mainly of editing and proofreading and peer review. There was no journal development work. At some point in the early 1980s, production and peer review were split into separate departments and Richard then headed a group of journals consisting of Journal of Physics C: Solid State Physics, Journal of Physics D: Applied Physics and Journal of Physics F: Metal Physics, Semiconductor Science and Technology, Superconductor Science and Technology, Plasma Physics and Controlled Fusion, and later Nanotechnology and Modelling and Simulation

    Certain molten complexes of Li salts and solvents can be regarded as ionic liquids. In this study, the local structure of Li(+) ions in equimolar mixtures ([Li(glyme)]X) of glymes (G3: triglyme and G4: tetraglyme) and Li salts (LiX: lithium bis(trifluoromethanesulfonyl)amide (Li[TFSA]), lithium bis(pentafluoroethanesulfonyl)amide (Li[BETI]), lithium trifluoromethanesulfonate (Li[OTf]), LiBF4, LiClO4, LiNO3, and lithium trifluoroacetate (Li[TFA])) was investigated to discriminate between solvate ionic liquids and concentrated solutions. Raman spectra and ab initio molecular orbital calculations have shown that the glyme molecules adopt a crown-ether like conformation to form a monomeric [Li(glyme)](+) in the molten state. Further, Raman spectroscopic analysis allowed us to estimate the fraction of the free glyme in [Li(glyme)]X. The amount of free glyme was estimated to be a few percent in [Li(glyme)]X with perfluorosulfonylamide type anions, and thereby could be regarded as solvate ionic liquids. Other equimolar mixtures of [Li(glyme)]X were found to contain a considerable amount of free glyme, and they were categorized as traditional concentrated solutions. The activity of Li(+) in the glyme-Li salt mixtures was also evaluated by measuring the electrode potential of Li/Li(+) as a function of concentration, by using concentration cells against a reference electrode. At a higher concentration of Li salt, the amount of free glyme diminishes and affects the electrode reaction, leading to a drastic increase in the electrode potential. Unlike conventional electrolytes (dilute and concentrated solutions), the significantly high electrode potential found in the solvate ILs indicates that the solvation of Li(+) by the glyme forms stable and discrete solvate ions ([Li(glyme)](+)) in the molten state. This anomalous Li(+) solvation may have a great impact on the electrode reactions in Li batteries.

    Modelling the transport processes in a vadose zone, e.g. modelling contaminant transport or the effect of the soil water regime on changes in soil structure and composition, plays an important role in predicting the reactions of soil biotopes to anthropogenic activity. Water flow is governed by the quasilinear Richards equation. The paper concerns the implementation of a multi-time-step approach for solving a nonlinear Richards equation. When modelling porous media flow with a Richards equation, due to a possible convection dominance and a convergence of a nonlinear solver, a stable finite element approximation requires accurate temporal and spatial integration. The method presented here enables adaptive domain decomposition algorithm together with a multi-time-step treatment of actively changing subdomains.

    Molten mixtures of lithium chloride and metallic lithium are of significant interest in various metal oxide reduction processes. These solutions have been reported to exhibit seemingly anomalous physical characteristics that lack a comprehensive explanation. In the current work, the physical chemistry of molten solutions of lithium chloride and metallic lithium, with and without lithium oxide, was investigated using in situ Raman spectroscopy. The Raman spectra obtained from these solutions were in agreement with the previously reported spectrum of the lithium cluster, Li8. This observation is indicative of a nanofluid type colloidal suspension of Li8 in a molten salt matrix. It is suggested that the formation and suspension of lithium clusters in lithium chloride is the cause of various phenomena exhibited by these solutions that were previously unexplainable.

    The generalized Chapman-Richards model was derived from the Chapman-Richards function in which parameters η,κ and m were unconstrained.Based on the structure of solutions and biological interpretations,the model could be classified into eight cases(three categories)at all and among them only 4 kinds of cases are suitable in forestry that represent four typical growth patterns of trees and stands.For each of 4 equations,the model properties and biological interpretations for parameters were discussed in detail.The generalized chapman-Richards model was capable of describing a wide range of growth curves that was asymptotic or nonasymptotic,with or without inflection point.In order to illustrate the versatility of the model,it was fitted to a group of data sets conceming the DBH growth of cryptomeria plantations with 4 initial densities and the DBH and height growth of natural Korean pine tree.Comparing the generalized Chapman-Richards function and the Sohnute model,it was found that the parameters and expressions of the two modets were interchangeable in theory,and the fitting results were explicitly identical in empirical applications.

    1984-01-01

    Four sigmoid growth curve models for birds were compared using the daily body masses and primary-feather lengths of 35 nestling tree swallows (Tachycineta bicolor). The Richards model was superior to the von Bertalanffy, Gompertz, and logistic models for body mass, but not for primary-feather length. The latter models have fixed growth forms and are special cases of the flexible Richards model. Owing to parameter correlations, the Richards model was very sensitive to the starting parameter values for the numerical computer fitting routines. The lack of data leading up to the asymptote made it difficult to calculate good starting values for primary-feather length. None of the models tested was completely satisfactory for primary-feather length, as indicated by nonrandomly distributed residuals over time. The log transformation was appropriate for body mass. It homogenized the residual variances and increased the explained percentage of variation. The explained percentage of variation was a useful selection criterion for the best-fitting model, especially since it was directly related to randomness in the distribution of the residuals and homogeneity of residual variances. However, even percentages of variation exceeding 99.5%, did not necessarily indicate an excellent fit. The Richards model did not yield more model parameters for growth curve analysis, because the shape parameter and the growth rate constant were almost perfectly correlated.

    Gilbert, Kenneth E.

    2008-08-01

    In the preface to "Predicting Outdoor Sound," the authors say they regard their book as complementary to the book, "Computational Acoustics," by Erik M. Salomons. Further, they say that workers in outdoor sound would be wise to own both books. With these statements in mind, it seems prudent to briefly compare the two books. Put simply, "Computational Acoustics" is mainly about using full-wave, numerical models to predict long-range sound propagation in a realistic atmosphere over irregular, but otherwise simple, terrain. In contrast, "Predicting Outdoor Sound" is mainly about how to predict sound propagation in a homogeneous atmosphere over surfaces that range from simple flat impedance planes to very complex structures such as realistic barriers and buildings. There are other important differences as well. While "Computational Acoustics" is largely theoretical, "Predicting Outdoor Sound" has a wealth of experimental measurements and empirical prediction schemes. Specifically, Chapters 1-6 contain in-depth discussions of propagation in a homogeneous atmosphere over a flat, finite impedance surface. A multitude of ground impedance measurements and models are discussed in these chapters. Chapter 7 discusses the effect of source motion. Chapter 8 considers sound propagation over a flat surface with a horizontally varying impedance. Chapters 9 and 10 discuss, respectively, the performance of outdoor noise barriers and the effects of vegetation, trees and turbulence. Chapter 11 considers approximate analytic models for sound propagation that include the effects of a finite impedance surface, refraction, and turbulence. In Chapter 12, a number of currently popular, semi-empirical noise prediction schemes are discussed. Chapter 13, the final chapter, discusses sound and noise in an urban environment, with consideration of such issues as street canyons and building facades. Although the book probably would not serve well as a stand-alone text, the authors have nevertheless succeeded admirably in fulfilling their purpose: "…to provide a comprehensive reference about aspects of outdoor sound and its prediction that should be useful to practitioners, and yet is respectable from the academic point of view." As a complete and authoritative source of information on the effects of surfaces of all kinds (ground impedance, barriers, buildings, etc.) on sound propagation, "Predicting Outdoor Sound" is unique and indispensable.

    One cannot survey the field of surface chemistry without encountering the name of Richard Lambert. Over the years, his research addressed a broad range of topics of which the underlying theme is study of the structure and reactivity of solid surfaces, with the aim of contributing to fundamental understanding of physical/chemical phenomena and to their exploitation in the invention and development of new materials and technologies. During this voyage, Richard and his collaborators have made use of a variety of methods including laboratory-based spectroscopies, imaging methods, synchrotron radiation techniques supported by collaborations with colleagues in theory, to elucidate the chemistry of reactions occurring over a wide range of pressures at gas/solid and liquid/solid interfaces.

  11. Die Musik Richard Wagners im Banat und in Rumänien. Eine Rezeptionsgeschichte

    2015-12-01

    Full Text Available Richard Wagner – an ihm schieden sich die Geister schon während seines Lebens. Dies geschah nicht nur in seinen deutschen Wirkungsorten, sondern auch im Südosten Europas. Schon früh fanden seine Werke auch im Banat und in Bukarest eine weite Verbreitung und das musikliebende Publikum mischte sich damals bereits in Pro- oder Kontra-Wagner-Diskussionen ein. In einem multikulturellen Raum wie das Banat, mit jahrhundertalten multiethnischen Erfahrungen und Traditionen, stieß der Wagnerkultus zuerst auf Ablehnung, später, ab 1930, wurden seine antisemitischen Anschauungen von den faschistischen Kreisen Rumäniens demagogisch missbraucht – ähnlich wie im restlichen Europa. Doch diese besondere Seite der Richard-Wagner-Rezeption hat auch eine faszinierende Auswirkung auf das allgemeine Musikleben in Rumänien und im Banat hinterlassen.

    Full Text Available The article features an interview with Sir Richard Eyre, a long-time Director of the Royal National Theatre in London and the director of the production of William Shakespeare's tragedy King Lear in the very same  theatre in 1997, which also saw a successful film  version. Sir Richard openly spoke about  his dilemmas as a director in the process of staging  the play, finding  the right east, about rehearsals and the first night performance, as well as about some key scenes interpreted by him somewhat  differently, although he essentially firmly relied on the text and the more traditional staging  of this famous Shakespeare's tragedy.

    Presents Richard Rogers as the 2001 winner of the American Psychological Association Award for Distinguished Contributions to Research in Public Policy. "Richard Rogers casts a long shadow over the realm of psychological research with public policy implications. His achievements concerning criminal responsibility and malingering have been important and lasting, but his most uniquely impactful contribution to public policy is his enhancement of our understanding of the constitutional protections embodied in Miranda rights. His investigations have exploded the myth of a single, easily understood Miranda warning. The ramifications of this work are profound, especially for socially marginalized populations, and include its direct acknowledgment as the impetus for critical developments in American Bar Association policy on custodial interrogations."

    This study was undertaken to describe the growth pattern of the pearl gray Guinea fowl. Using BW data from hatch to 22 wk, 3 nonlinear mathematical functions (Richards, Gompertz, and logistic) were used to estimate growth patterns of the pearl gray guinea fowl. The logistic and Gompertz models are a special case of the Richards model, which has a variable point of inflection defined by the shape or growth trajectory parameter, m. The shape parameter m was 1.08 and 0.98 in males and females, respectively, suggesting that the growth pattern of the pearl gray female guinea fowl is Gompertz. The pearl gray guinea fowl exhibited sexual dimorphism for their growth characteristics. From the Gompertz model, the asymptotic BW, growth rate, and age at maximum growth were 1.62 kg, 0.22 kg/wk, and 6.65 wk in males, respectively, and 1.70 kg, 0.19 kg/wk, and 6.70 wk in females, respectively. The ages at maximum growth were 6.65, 6.47, and 8.12 wk for the Richards, Gompertz, and logistic models, respectively. The pearl gray guinea fowl females have a higher asymptotic BW compared with the males. The average asymptotic BW of about 1.57 kg for both sexes predicted by the logistic model was below the average predicted BW from the Richards (1.66 kg) and Gompertz (1.67 kg) models, respectively, at 22 wk of age. The inverse relationship between the asymptotic weight and both relative growth and age at maximum growth of the pearl gray guinea fowl is similar to that of chickens, quail, and ducks. Success in studying the growth characteristics of guinea fowl will contribute to the efforts of genetically improving this least-studied avian species.

    Objective To investigate the roles of maspin and kail expression in tumorigenesis and progression of gastric cancer.Methods Maspin and kail expressions were detected in normal gastric mucosa (n = 182), gastric dysplasia (n = 69), and gastric cancer (n = 113) by immunohisto-chemistry. Their expressions were compared with clinicopathological parameters of tumors. Relationship between maspin and kai1 expression was also concerned in gastric cancer.Results The positive rates ofmaspin expression were 79.8% (145/182), 75.4% (52/69), and 50.4% (57/113) in normal gastric mucosa, gastric dysplasia, and gastric cancer, while those of kail expression were 81.9% (149/182), 65.2% (49/69),and 58.4% (66/113) in corresponding tissues respectively. Gastric cancer less frequently expressed maspin than the normal gastric mucosa and gastric dysplasia (P < 0.05), while dysplasia and cancer showed less frequent expression of kail than normal mucosa (P < 0.05). Maspin expression showed negative association with invasive depth, metastasis, Lauren's and histological classifications (P < 0.05), but not with tumor size, Borrmann's classification, growth pattern or TNM staging (P > 0.05). Kail expression was negatively correlated with invasive depth, metastasis, growth pattern, Lauren's and histological classifications (P < 0.05), but not with tumor size, Borrmann's classification or TNM staging (P > 0.05). Maspin and kail were collaboratively expressed in gastric cancer (P < 0.05).Conclusions Down-regulated expressions of maspin and kail play an important role in gastric carcinogenesis. Abnormal expression of maspin and kail might have inhibitory effects on invasion and metastasis of gastric cancer and act as an effective and objective marker to indicate the pathobiological behaviors of gastric cancer.

    This paper examines diagnostic practices using the early twentieth-century medical literature and the patient correspondence and records from the clinic of Richard Cabot. What shaped medicine's rapidly growing persuasive authority in the twentieth century? Diagnostic expertise demonstrated the doctor's control over disease but offered a service of ambiguous value to patients. Cabot and his peers offered differing views on how new diagnostic techniques would influence their relationships to their patients. In his busy private clinic Cabot put into effect an exacting diagnostic process, modeled on his innovative Clinicopathological Conferences. The people who came to the clinic often sought his technical expertise but accepted his diagnostic practices and opinions sometimes only provisionally.

    2003-05-01

    Richard Rufus of Cornwall offered a novel solution to the problem of mixture raised by Aristotle. The puzzle is that mixts or mixed bodies (blood, flesh, wood, etc.) seem to be unexplainable through logic, even though the world is full of them. Rufus's contribution to this long-standing theoretical debate is the development of a modal interpretation of certain Averroistic doctrines. Rufus's account, which posits that the elemental forms in a mixt are in accidental potential, avoids many of the problems that plagued non-atomistic medieval theories of mixture. This paper is an initial examination of Rufus' account.

Precisely this shift of the theological discussion to the historical domain provided Verstegen with the means for an effective authorization of his arguments (including citations, truth claims and self-presentation as a critical investigator. In addition, Verstegen made smart use of the iconography of St. Willibrord on the title page of the work. He thus created a vivid image that would facilitate the recollection of the text's main arguments.

    This paper discusses the 43+ year collaboration of Arthur Popper and Richard Fay. Over these years, we have co-authored over 30 papers and 55 books. The collaboration benefits from a strong friendship that includes our spouses and children. By any measure, our collaboration must be seen as being successful. The basis for this success is, we think, twofold. First, we have very complementary and overlapping research interests. This has enabled us to tackle issues, whether in research or in planning meetings or books, from different perspectives. Second, a hallmark of our successful collaboration has been our deep and close friendship and the extension of that friendship to our spouses and children. In this paper, we discuss some of the events that have shaped our collaboration, and some of the people who have impacted our lives.

    2016-06-03

    The Li-Fraumeni syndrome is characterized clinically by the appearance of tumors in multiple organs generally at an early age. This hereditary condition is caused by germinal mutations in the TP53 gene, which codifies for the tumoural suppressor gene p53. We present the case of a patient aged 31 with clinical and molecular diagnosis of Li-Fraumeni syndrome who presented two synchronous tumors: a leiomyosarcoma on the forearm and a phyllodes breast tumour. She had a family history of cancer, including a son diagnosed with a cortical adrenal carcinoma when he was three years old, who died at five from the disease. Furthermore, her maternal grandmother and great-grandmother died of stomach cancer at 56 and 60 years old, respectively, while her other great-grandmother and a great aunt presented with breast cancer at the ages of 60 and 40, respectively. After genetic counseling, complete sequencing and analysis of duplications and deletions in the TP53 gene were ordered prior to diagnosis. The molecular analysis of a DNA sample taken from peripheral blood lymphocytes revealed the germinal mutation c.527G>T (p.Cys176Phe) on exon 5 of the TP53 gene, a deleterious mutation described previously in tumoural tissues. To our knowledge, this is the first published case in Colombia of Li-Fraumeni syndrome with confirmed molecular diagnosis. The diagnosis and management of Li-Fraumeni syndrome should be performed by a multidisciplinary team, and genetic counselling should be offered to patients and their relatives.

  19. The wish to be hated: Richard III's villainy in pursuit of the bad-enough object.

    Science.gov (United States)

    Rosen, Irwin C

    2013-12-01

    Richard III's legendary villainy, in addition to its obvious role in furthering his ambition for power, arguably had deeper psychological roots: motives embedded in the developmental unfolding of his complex relationship with a severely traumatized and rejecting mother. The theoretical formulations of Ronald Fairbairn are used to show that Richard's villainy preserved and perpetuated a specific object-tie to his mother, that of being her demonized and despised "child of hate," and that many of his victims, especially women, served as maternal surrogates in his lifelong quest to replicate his maternal "bad-enough object." Similar patterns of severe relational disturbance pervade many of the mother-son dyads portrayed in Shakespeare's other plays, a repetitive theme that may well be linked to the playwright's own mother's history of severe loss and depression during his infancy and its impact on her ability to provide her son with bountiful emotional nurturance. A collateral issue is also addressed-the narcissistically embedded bonding difficulties between parents and their disabled children, whose visible impairment is said to give rise to greater adjustment problems than does the medical severity of the condition itself.

  20. Persona-lly Appealing: Benjamin Franklin’s Poor Richard and Authorial Self-Representation

    Directory of Open Access Journals (Sweden)

    Patricia F. Tarantello

    2016-06-01

    Full Text Available While scholarship on Benjamin Franklin’s Autobiography describes his use of persona in nuanced terms, scholarship on Franklin’s earlier writings tends to characterize his use of persona as simply a device he used to eliminate personal details from his texts. This article, focused on Franklin’s Poor Richard persona, argues that he conceived of literary persona not simply as a tool to protect his anonymity, but also as a means of self-promotion and self-representation. Franklin used Poor Richard to make a space for himself in the literary marketplace, build a readership for the almanac, and create a positive public reputation for himself. Franklin’s early experiments in performing sincerity and authenticity through an invented personality prefigure the performances of identity he would deploy through his authorial persona in The Autobiography. Thus, by examining Franklin’s construction of identity in Poor Richard’s Almanack, we learn more about how he crafted a public identity for himself.

  1. Charisma and Routine: Shaping the Memory of Brother Richard and Joan of Arc

    Directory of Open Access Journals (Sweden)

    Andrew Brown

    2012-12-01

    Full Text Available The extraordinary life and fate of Joan of Arc are well known; so is her association with the prophetic preacher, Brother Richard, who predicted the Apocalypse. Less well explained is why contemporaries initially took such an interest in this association, and how and why it began to fade from official memory after Joan’s death. Max Weber’s concepts of “charisma” and “routinization” offer valuable tools to deal with these questions. Both Joan and Richard have earned the title “charismatic” but interest in the preacher has generally been secondary to interest in the Maid. A more rigorous adoption of Weber’s meaning of charisma, however, helps to clarify what the relative importance of these figures was in the eyes of contemporaries. It also shifts attention to the significance of messianic prophecy in the years surrounding Joan’s life, the anxieties it generated and the way it was dealt with. In this context, the processions and commemorative ceremonies organized by townspeople, churchmen and royalty during this period deserve further analysis. Seen as forces of “routine”, these ceremonies assume a greater significance than they have usually been granted, as processes that managed the memory of charismatic phenomena.

    Full Text Available The leaf area growth in maize was approximated basing on the Richards function in the form of: y=A[l+b exp(-kt]1/(1-m . The constant coefficients of the Richards function were found by means of the Marquardt's method. The initial values of parameters were given basing on results of the preliminary approximation of the growth process by means of logistic function y = A[l+b exp(-kt]-1.

  6. Translation as Cultural Mediation in the Works of I. A. Richards

    2002-01-01

    This essaydiscusses the works of I.A. Richards ( 1893 - 1979), one of the founders and leading practitioners of the New Criticism,in the theory and practice of translation. Beginning with his book Mencius on the Mind (1932), which resulted from his initial stay in China as Visiting Professor at Tsinghua University, Richards approached the problem of translation in conjunction with his theory of multiple definition and the plurality of meaning in language. His-later works in conjunction with his teaching i n the program of General Education at Harvard University focused on the major texts of Ancient Greek culture, Homer' s Iliad and Plato' s Republic. His versions of both these works in simplified English are intended to make them accessible to the general reader. Finally, it is argued that Richards'works as a poet in the final stage of his career, when he produced a free adaptation of the Book of Job from the Bible, constitutes an exercise in cultural mediation through dramatic performance.%本文讨论了新批评代表人物和在翻译理论与实践中都有建树的理查兹的著作.《孟子论心智》(1 932)是他在清华大学任客座教授时的产物,在这本书中,理查兹探讨了与他的多重定义之理论及语言的多重意义相关的翻译问题.他后期的著述则与他在哈佛大学从事普通教育相关,那时他所关注的是古希腊文化的主要文本,即荷马的《伊利亚特》和柏拉图的《理想国》.他用简单的英文对这两部著述的翻译意在使普通读者能读懂.最后,作者论证道,理查兹后期作为一位诗人还改编了圣经的约伯书,从而形成了他通过戏剧表演来达到一种文化中介的实践.

    2015-03-01

    Full Text Available In response to the recent call to re-evaluate what C.S. Lewis called the ‘Drab Age’, the article reassesses one sixteenth-century poem, The Rewarde of Wickednesse (1574, and its author, Richard Robinson. The poem is framed in such a way that the topos of service is central to an understanding of Robinson’s authorial identity, an identity determined by his proclaimed status within the household of the sixth Earl of Shrewsbury. The poet claims to be one ‘of a hundreth’ serving the family during the captivity of Mary, Queen of Scots. The article locates the Rewarde of Wickednesse within the relevant geographical, literary and socio-political contexts and reveals aspects of Robinson’s artistry that have remained hitherto unexplored.

    Gandhi visited London on several occasions. During two of these visits, when he was a law student from 1888 and again in 1914, he met Thomas Richard Allinson, a controversial doctor whose name was erased from the Medical Register in 1892. While in London studying for the bar, Gandhi was influenced in his search for a suitable vegetarian diet by the writings and personal support of Allinson. Although disagreeing profoundly with Allinson's views on birth control, he spoke up in defence of his right to hold them--probably the first time Gandhi challenged authority and an occasion which shows him as a tongue-tied young man but even then having a personal moral code that gives insight into the character of the future Mahatma. On Gandhi's further visit to England in 1914 Allinson, although no longer on the Medical Register, treated Gandhi for pleurisy, apparently partially successfully when orthodox medicine had failed.

  9. Analytical and grid-free solutions to the Lighthill-Whitham-Richards traffic flow model

    KAUST Repository

    Mazaré, Pierre Emmanuel

    2011-12-01

    In this article, we propose a computational method for solving the Lighthill-Whitham-Richards (LWR) partial differential equation (PDE) semi-analytically for arbitrary piecewise-constant initial and boundary conditions, and for arbitrary concave fundamental diagrams. With these assumptions, we show that the solution to the LWR PDE at any location and time can be computed exactly and semi-analytically for a very low computational cost using the cumulative number of vehicles formulation of the problem. We implement the proposed computational method on a representative traffic flow scenario to illustrate the exactness of the analytical solution. We also show that the proposed scheme can handle more complex scenarios including traffic lights or moving bottlenecks. The computational cost of the method is very favorable, and is compared with existing algorithms. A toolbox implementation available for public download is briefly described, and posted at http://traffic.berkeley.edu/project/downloads/lwrsolver. © 2011 Elsevier Ltd.

    Full Text Available After the death of Wagner and Brahms, Richard Strauss emerged as one of the most important and popular in the history of music of the 20th. century composers. His eventful and turbulent life and professional career, as well as the decades that he lived, were marked by the female reality. It is undeniable that the women in the life of Strauss, were strong and had distinctive personalities, they left marks on him so deep that he felt necessary to take them to the scene, not only as a valuable contribution to the female character type, but also as a personal therapeutic exercise. Thus, real and fictional women are confused in their works in a unique creative process: of the man-artist

  11. Richard Feynman's popular lectures on quantum electrodynamics: The 1979 Robb lectures at Auckland University

    Science.gov (United States)

    Dudley, J. M.; Kwan, A. M.

    1996-06-01

    The subject of quantum electrodynamics (QED) was the subject of QED—The Strange Theory of Light and Matter, the popular book by Richard Feynman which was published by Princeton University Press in 1985. On p. 1, Feynman makes passing reference to the fact that the book is based on a series of general lectures on QED which were, however, first delivered in New Zealand. At Auckland University, these lectures were delivered in 1979, as the Sir Douglas Robb lectures, and videotapes of the lectures are held by the Auckland University Physics Department. We have carried out a detailed examination of these videotapes, and we discuss here the major differences between the original Auckland lectures and the published version. We use selected quotations from the lectures to show that the original lectures provide additional insight into Feynman's character, and have great educational value.

  12. Richard Wagner, Louis de Fourcaud, and a Path for French Opera in the 1880s

    Directory of Open Access Journals (Sweden)

    Marie-Hélène Benoit-Otis

    2012-05-01

    Full Text Available In a much-quoted interview with Richard Wagner conducted by the French critic Louis de Fourcaud in 1879, and published in different versions in 1880, 1884, and 1886, the composer allegedly advised the French to write operas drawing on their own legendary sources. Contemporary works such as d’Indy’s Fervaal, Chausson’s Le Roi Arthus, and Massenet’s Esclarmonde suggest that Fourcaud’s interview did indeed have a profound impact on the Wagnerian movement in France. However, a close examination of the sources reveals that his text owes much less to Wagner than scholars have previously assumed: in fact, evidence suggests that the most important part of the interview (that is, the advice to French composers was added by Fourcaud himself after Wagner’s death.

  13. Digital scenography and the mimetic aporia of Richard Wagner's Ring Cycle

    Directory of Open Access Journals (Sweden)

    Jason R. D’Aoust

    2015-12-01

    Full Text Available This article explores the visual friction between the concealment of technology and the need to stage mimetic scenes in Richard Wagner's Der Ring des Nibelungen. The article relies on the critical reception of the Wagnerian Gesamtkunstwerk in musicology, as well as in media, performance, and theatre studies. Drawing on productions and commentaries critical of the iconic Gesamtkunstwerk's attempted retrieval of a lost natural state, the article examines correlations between phantasmagoria, special effects, movement detection technology, and the interactive devices of multimedia and digital scenography. These correlations are framed within a theoretical methodology of historical discourse and media archaeologies. Three specific productions of the Ring are discussed, namely the inaugural and centenary productions at the Bayreuth Festspielhaus, as well as Robert Lepage's production for the Metropolitan Opera of New York in 2010–2012.

    2014-05-01

    Full Text Available In this timely book Richard Peet and his team lay the foundation with an excellent analysis of the process of globalisation and the resultant emergence of the global economy. The authors are especially critical of the increasing influence of institutions like the International Monetary Fund (IMF, World Bank and World Trade Organisation (WTO on the economy and the consequences experienced by peoples, cultures and the environment. The single ideology of neo-liberalism is blamed for the undesirable outcomes. This book considers concepts of power, political interest, hegemony, discourse, responsibility and the power of practicality, in critically examining the IMF, World Bank and WTO. The conclusion is reached that “all three institutions play roles greatly different from those originally agreed to under the charters that set them up”.

  15. Influences of ancient Greek spirit on music romanticism as exemplifies in Richard Wagner's Gesamtkunstwerk

    Directory of Open Access Journals (Sweden)

    Siopsi Anastasia

    2005-01-01

    Full Text Available The romantics' ideal of the arts' collaboration (Mischgedichte finds its most substantial equivalent in Richard Wagner's (1813-1883 "total work of art" (Gesamtkunstwerk. This theory for the restoration of the 'lost' unity of arts was elaborated in many theoretical essays of Wagner and 'applied' in his music dramas. Unity of arts, as well as unity of arts with nature existed according to Wagner in Ancient Greece while drama was the epitome of all expressive elements of nature. This "new art of the future", which Wagner envisaged, would restore the 'wholeness' of ancient Greek drama. It is the purpose, therefore, of this study to analyze mainly from an aesthetic point of view the influences of ancient Greek spirit on romantic thought, by focusing on Wagner's work.

  17. Richard Byrd, Technological Explorer: Polar Exploration, the Machine, and Heroic Masculinity in Interwar America.

    Science.gov (United States)

    Cronin, Marionne

    2016-04-01

    In May 1926, U.S. newspapers were full of the story that Richard Byrd, an American aviator, had become the first person to reach the North Pole by air. The announcement triggered patriotic outpourings across the country and Byrd was widely hailed as a national hero. The young aviator's flight was part of a burgeoning interwar expeditionary practice that placed machines at the heart of new modes of exploration. This development, however, challenged preexisting notions of masculine heroism and threatened to undercut the explorer's heroic status. How then, could Byrd become a national hero? This article analyzes his depiction in the press as a means of exploring interwar Americans' efforts to renegotiate their notions of heroic masculinity in a way that could accommodate the machine without threatening the hero's status. In the process, it argues, these narratives and images defined a new sort of popular hero: the technological explorer.

    2015-01-01

    This article pays homage to the life and work of a veritable pioneer in toxicology and drug metabolism, namely a Welshman, Richard Tecwyn Williams, FRS. Professor Williams, or RT as he was known, made major contributions to knowledge about the metabolism and toxicology of drugs and xenobiotics during a scientific career spanning nearly 50 years. Author or coauthor of close to 400 research articles and reviews, including a classic book, entitled Detoxication Mechanisms, Williams and his research school investigated virtually all aspects of drug metabolism, especially conjugations. In particular, the concepts of phase 1 and phase II metabolic pathways were introduced by Williams; the biliary excretion of drugs was extensively studied as were species differences in drug metabolism and detoxication. Besides investigating the metabolism of many pharmaceutical drugs, such as sulfonamides and thalidomide, Williams and his group investigated the disposition and fate in the body of organic pesticides and recreational drugs of abuse, such as amphetamine, methamphetamine and lysergic acid diethylamide (LSD).

    Science.gov (United States)

    Russo Krauss, Chiara

    2017-01-01

    This essay provides a fresh account of the break between Oswald Külpe and his master Wilhelm Wundt. Kurt Danziger's reconstruction of the "repudiation" of Wundt, which has become the canon for this significant episode of history of psychology, focused on the supposed influence of Ernst Mach on this set of events, overshadowing the other exponent of Empiriocriticism: Richard Avenarius. Analyzing archival documents and examining anew the primary sources, the paper shows that Avenarius was himself a member of Wundt's circle, and that his "repudiation" of the master paved the way for Külpe. The essay points out the original anti-Wundtian aspects of Avenarius' notion of psychology, thus showing how they were then adopted by Külpe.

    Carl Friedrich Richard Foerster (1825-1902) was a German who was born in the Polish city Leszno. He studied medicine at the Medical Faculty of Breslau (now Wroclaw, Poland) University, and later in Heidelberg and Berlin. From 1855, he worked in Breslau, where he established in 1857 the first ophthalmology clinic. Later, he became a professor in ophthalmology, the first director of the Department of Ophthalmology at the University of Breslau, and even the rector of this University. Forster did many pioneering works on visual fields, invented a photometer and the first perimeter, known for many years as the Foerster perimeter. Moreover, he studied night blindness, visual field changes due to different pathologies, and many eye diseases, including glaucoma, cataract, retinal and choroidal diseases.

    Professor Richard H. Dalitz passed away on January 13, 2006. He was almost 81 years old and his outstanding contributions are intimately connected to some of the major breakthroughs of the 20th century in particle and nuclear physics. These outstanding contributions go beyond the Dalitz Plot, Dalitz Pair and CDD poles that bear his name. He pioneered the theoretical study of strange baryon resonances, of baryon spectroscopy in the quark model, and of hypernuclei, to all of which he made lasting contributions. His formulation of the "$\\theta-\\tau$ puzzle" led to the discovery that parity is not a symmetry of the weak interactions. A brief scientific evaluation of Dalitz's major contributions to particle and nuclear physics is hereby presented, followed by the first comprehensive list of his scientific publications, as assembled from several sources. The list is divided into two categories: the first, main part comprises Dalitz's research papers and reviews, including topics in the history of particle physics, ...

    LiFePO{sub 4} has several potential advantages in comparison to the transition metal oxide cathode materials used in commercial lithium-ion batteries. However, its low intrinsic electronic conductivity ({approx} 10{sup -9} S/cm) is problematic. We report here a study by soft x-ray absorption/emission spectroscopy of the electronic properties of undoped LiFePO{sub 4} and Li-doped LiFePO{sub 4} in which Li{sup +} ions are substituted for Fe{sup 2+} ions in an attempt to increase the intrinsic electronic conductivity. The conductivities of the Li{sub 1+x}Fe{sub 1-x}PO{sub 4} samples were, however, essentially unchanged from that of the undoped LiFePO{sub 4}. Nonetheless, evidence for changing the electronic properties of LiFePO{sub 4} by doping with excess Li+ was observed by the XAS/XES spectroscopy. New pre-edge features the O-1s XAS spectrum of Li{sub 1.05}Fe{sub 0.95}PO4 is a direct indication that the charge compensation for substitution of Fe{sup 2+} by Li{sup +} resides in the unoccupied O-2p orbitals. A charge transfer (CT) excitation was also observed in the doped material implying that the unoccupied O-2p orbitals created by doping are strongly hybridized with unoccupied Fe-3d orbitals of neighboring sites. However, the strong covalent bonding within the (PO{sub 4}){sup 3-} anions and the large separation of the Fe cations means that the charge created by doping is not delocalized in the manner of electrons or holes in a semiconductor.

    Full Text Available Au with Pd nanoparticles were synthesized and coated onto the spinel LiMn2O4 via a coprecipitation calcination method with the objective to improve the microstructure, conductivity, and electrochemical activities of pristine LiMn2O4. The novel LiPdAuxMn2-xO4 composite cathode had high phase purity, well crystallized particles, and more regular morphological structures with narrow size distributions. At enlarged cycling potential ranges the LiPdAuxMn2-xO4 sample delivered 90 mAh g−1 discharge capacity compared to LiMn2O4 (45 mAh g−1. It was concluded that even a small amount of the Pd and Au enhanced both the lithium diffusivity and electrochemical conductivity of the host sample due to the beneficial properties of their synergy.

The search of perfection and model of ideal man is one of these factors. Truly Mantiq Al-tair by Attar-e-Neishaburi is the most beautiful symbolic works of the east in this field (search of perfection which has been imitated by many of writers and poets in all around the world. Richard Bach – one of the idealist writers of the west – has presented almost a similar model named “Jonathan Livingston Seagull”. Certainly from the point of view of theme and the complexity of the story, it is not as great as Mantiq Al-tair by Attar. Is the philosophy of thinking of this writer affected by the theosophy of Attar and his thinking? Or the similarities of these two literary-mystic works, even if Richard Bach doesn’t have seen Mantiq Al-tair by Attar, have arisen from the common innate and inherent ideals among humans and are completely natural and believable? This writing is an effort to answer these questions. In addition it is a comparison between Mantiq Al-tair by Attar-e-Neishaburi and Jonathan Livingston Seagull by Richard Bach. key words: Mantiq Al-tair, Attar-e-Neishaburi, Jonathan Livingston Seagull, Richard Bach, perfect man

    Everything old is new again. In a recent "Point of View" editorial commentary in "Educational Technology," Richard E. Clark revisits the now-famous media-effects debate with a focus on serious games. Clark argues that serious games have little to offer that improves upon traditional methods. This article responds to those claims. While Clark's…

    Colgan, James P [Los Alamos National Laboratory

    2008-01-01

    Electron-impact ionization cross sections for Li{sub 2} and Li{sup +}{sub 2} are calculated using a configuration-average distorted-wave method. Bound orbitals for the molecule and its ions are calculated using a single configuration self-consistent field method based on a linear combination of Slater-type orbitals. The bound orbitals are transformed onto a two-dimensional lattice ({tau}, {theta}), which is variable in the radial coordinate and constant in the angular coordinate, from which Hartree with local exchange potentials are constructed. The single particle Schrodinger equation is then solved for continuum distorted-waves with S-matrix boundary conditions. Total ionization cross sections for Li{sub 2} at an equilibrium internuclear separation of R = 5.0 and for Li{sup +}{sub 2} at an equilibrium internuclear separation of R = 5.9 are presented.

    2010-12-01

    Full Text Available In this work we study the problem of modeling identification of a population employing a discrete dynamic model based on the Richards growth model. The population is subjected to interventions due to consumption, such as hunting or farming animals. The model identification allows us to estimate the probability or the average time for a population number to reach a certain level. The parameter inference for these models are obtained with the use of the likelihood profile technique as developed in this paper. The identification method here developed can be applied to evaluate the productivity of animal husbandry or to evaluate the risk of extinction of autochthon populations. It is applied to data of the Brazilian beef cattle herd population, and the the population number to reach a certain goal level is investigated.Neste trabalho estudamos o problema de identificação do modelo de uma população utilizando um modelo dinâmico discreto baseado no modelo de crescimento de Richards. A população é submetida a intervenções devido ao consumo, como no caso de caça ou na criação de animais. A identificação do modelo permite-nos estimar a probabilidade ou o tempo médio de ocorrência para que se atinja um certo número populacional. A inferência paramétrica dos modelos é obtida através da técnica de perfil de máxima verossimilhança como desenvolvida neste trabalho. O método de identificação desenvolvido pode ser aplicado para avaliar a produtividade de criação animal ou o risco de extinção de uma população autóctone. Ele foi aplicado aos dados da população global de gado de corte bovino brasileiro, e é utilizado na investigação de a população atingir um certo número desejado de cabeças.

    A phase transition from the cubic CsCl-type structure (Pm-3m space group) into a tetragonal UPb-type structure (I4 1/amd) is observed for the LiAg binary compound at ambient conditions. The crystal structure of the tetragonal modification of the LiAg binary compound was solved by direct methods in SHELXS on the base of structure factors which were extracted from a powder diffraction pattern and refined by SHELXL and the Rietveld method ( a = 3.9605(1), c = 8.2825(2) Å, Bragg R-factor = 4.81, Rf-factor = 4.87). Elevated temperatures and/or a small Li-excess versus the equimolar composition favour the cubic structure whereas ambient and lower temperatures and/or a small Li-deficiency stabilize the tetragonal structure. This reconstructive transition is reversible but proceeds slowly.

    Full Text Available Albania, as well as a great part of the Balkan area in general, still suffers a lack of environmental studies especially in limnological research. The Dumre plateau, in Central Albania, is characterized by an extraordinary high number of karst lakes in a small geographic area. Despite their environmental peculiarity, very few biological data are to date available for these lakes, none on the zooplankton. For this reason, 15 water bodies located in the central area of the plateau were selected for a preliminary limnological survey carried out in the years 2008-2011. Neodiaptomus schmackeri (Poppe & Richard, 1892, a diaptomid calanoid copepod characterized by a South-Eastern Palearctic - Oriental distribution, and the most widely spread Neodiaptomus species in Asia, was found in 8 lakes of the Dumre area. This finding represents the first record of the species, and of the entire genus Neodiaptomus, for Europe. Several environmental variables were measured to characterize the lakes, and the co-occurring planktonic crustaceans were also identified. Taxonomical drawings and descriptions of the main morphological features of both sexes are herein provided in order to compare the Albanian populations of N. schmackeri with those of the native distribution area of the species. The possible causes which determined the occurrence of this non-indigenous species in several Dumre lakes are discussed.

    2006-03-29

    Professor Richard H. Dalitz passed away on January 13, 2006. He was almost 81 years old and his outstanding contributions are intimately connected to some of the major breakthroughs of the 20th century in particle and nuclear physics. These outstanding contributions go beyond the Dalitz Plot, Dalitz Pair and CDD poles that bear his name. He pioneered the theoretical study of strange baryon resonances, of baryon spectroscopy in the quark model, and of hypernuclei, to all of which he made lasting contributions. His formulation of the ''{theta} - {tau} puzzle'' led to the discovery that parity is not a symmetry of the weak interactions. A brief scientific evaluation of Dalitz's major contributions to particle and nuclear physics is hereby presented, followed by the first comprehensive list of his scientific publications, as assembled from several sources. The list is divided into two categories: the first, main part comprises Dalitz's research papers and reviews, including topics in the history of particle physics, biographies and reminescences; the second part lists book reviews, public lectures and obituaries authored by Dalitz, and books edited by him. This provides the first necessary step towards a more systematic research of the Dalitz heritage in modern physics.

  4. Richard Rorty:From Anti-metaphysical Neo-Pragmatism to Rejection of Philosophy

    Directory of Open Access Journals (Sweden)

    M. Akrami

    2010-01-01

    Full Text Available Richard Rorty is a neo-Pragmatist philosopher. For three decades, he has attacked the traditional philosophy (from Plato to Kant as well as any other epistemology searching for truth or claiming to mirror the nature in his philosophical works. Rorty holds that, according to the history of philosophy in his reading, there is no final answer to the traditional questions concerning knowledge, truth, and representation. These questions, therefore, should be dissolved and denied. He maintains that knowledge is justified belief, justification, however, being not the consequence of some correspondence between the theory or the statement, but the consequence of conversation, social practice, group consensus, and social solidarity. Rorty also thinks that democracy has priority on philosophy, disagreeing with the thesis that philosophy is the foundation of the rest of culture.Despite of usefulness of some elements and implications of Rorty’s metaphilosophy (such as his emphasis on freedom, democracy, and pluralism as well as his insisting on philosophical humility and avoiding scientific pride, it is faced with several problems, including 1 ignoring the referential and realist features of language, 2 confusing interpretation and reality, 3 eliminating the border between objectivity and subjectivity, 4 interfering of public and private life, and 5 ignoring the need of science, culture, technology and, in particular, politics, in philosophy. The authors try to show and analyze some elements of these problems.

  5. Health Effects Due to Radionuclides Content of Solid Minerals within Port of Richards Bay, South Africa

    Full Text Available This study assessed the radiological health hazards to various body organs of workers working within Transnet Precinct in Richards Bay in Kwazulu-Natal, South Africa due to radionuclide content of mineral ores often stored within the facility. Thirty samples were collected from five mineral ores (rock phosphate, rutile, zircon, coal and hematite and analyzed for 238U, 234U, 226Ra, 210Pb, 235U, 232Th, 228Ra, 228Th and 40K using delayed neutron activation analysis and low energy gamma spectroscopy. Rutile was found to be the most radioactive mineral ore within the facility with 210Pb concentration of 759.00 ± 106.00 Bq·kg−1. Effective annual dose rate in (mSv·y−1 delivered to different organs of the body: testes, bone marrow, whole body, lungs and ovaries from mineral ores were such that dose from mineral ores decreased in the order coal > rutile > rock phosphate > hematite > zircon. The organs with the highest received dose rate were the testes and this received dose was from coal. However, all of the calculated absorbed dose rates to organs of the body were below the maximum permissible safety limits.

  6. Mixed Lagrangian-Eulerian and Eulerian Approach to Discretizing Richards' Equation

    Science.gov (United States)

    Yeh, G. T.; Tsai, C. H.

    2014-12-01

    This paper presents a robust, efficient numerical solution involving the use of the mixed Lagrangian-Eulerian (LE) method and the Eulerian (L) approach for three dimensional simulations of variably saturated subsurface flow that is described by Richard's equation. The LE approach with its particle tracking algorithm and/or finite element methods (FEM) were employed to discretize interior nodes while the finite element method is selected to set up algebraic equations for boundary nodes. The use of FEM for boundary nodes alleviate the difficulty in dealing with flux and gradient types of boundary conditions. Extrapolations are no longer needed to handle flux or gradient type boundary conditions. In this new mixed LE&E approach, subsurface flow in variably saturated media can be efficiently dealt with. Three examples are provided to demonstrate the efficiency of the proposed approach. First, a one-dimensional column problem is used to compare the accuracy of the mixed LE&E approach versus the traditional Eulerian approach. Second, a three-dimensional drainage problem was simulated to compare the CPU time between two approaches. Third, a three-dimensional pumping well problem was simulated. In all three examples, the mixed LE&E using relatively large time steps yielded superior results in terms of the accuracy and computational efficiency in comparison with the conventional Eulerian approach. The proposed mixed LE&E approach may contribute to the efficient numerical solutions of problems involving moving sharp fronts problems such as groundwater in real-world watersheds.

    The increasingly strong interaction between biomedical and epidemiological research is one of the most important steps forward in medicine and public health since World War II. Crucial breakthroughs were the development of powerful observational epidemiological studies, the introduction of convincingly designed clinical trials, and meta-analyses to objectively summarise the results of multiple studies. For this progress, the work of Sir Richard Peto (born in 1943), epidemiologist and statistician at the University of Oxford, Great Britain, has been essential. Peto combined innovative methodological contributions with large-scaled empirical studies, often based on worldwide collaborations, with a special focus on smoking and health, treatment of breast cancer, and cholesterol-lowering interventions. His work both produced and evoked an impressive evidence base to improve clinical and public health practice. In accordance with the advice of a selection committee of the Royal Netherlands Academy of Arts and Sciences, he was awarded the Dr A.H. Heineken Prize for Medicine on 2 October 2008.

    Full Text Available One of the most important natural resources we have is the soil and it is of great interest to the society to take care of them and not to pollute it. In the study of this issue, we are going to consider one of the most common forms of soil contamination due to an infiltration process. It is therefore that it is essential to address study and clearly understand this process by developing a mathematician model, which will be a representation of this physicist phenomenon. Then design and implement a computer program that simulates the infiltration of liquid pollutants in a given area. In this paper we will develop a mathematical model for two-dimensional infiltration in the saturated zone of porous media, based on the equation in nonlinear partial differential Richards Also, It will present a numerical solution through finite element method and first order This paper shows the computational implementation using a simulator that presents graphically the process of pollution afflicting the ground, exposed to certain pollutants, such as the oil spill in regions of eastern Ecuador, wastewater near industrial complexes, among others, over a certain period of time. Finally, this paper will allow for remedial studies in the case are already contaminated soils or preventive areas established as hazardous.

    Full Text Available La filosofía del lenguaje surge como la posibilitadora de la búsqueda de la verdad, función que ha acompañado siempre a la filosofía desde su aparición en Grecia. Con el lenguaje como protagonista, recordamos que la verdad ha estado ligada a aquel gracias a la herencia occidental de nuestro pensamiento. En este contexto, Richard Rorty nos plantea que la verdad tan solo está en las proposiciones, fruto de lenguajes elaborados por los hombres. Esta visión se opone a conceptos filosóficos como el esencialismo y el representacionalismo, y a creencias como la labor sacerdotal del filósofo, entre otras cosas. Pero la consecuencia más dura del pensamiento de nuestro autor es la consideración de la filosofía como un género literario más, en el cual la metaforicidad ha estado presente en sus discursos a pesar de su pretensión de objetividad y de erigirse como la develadora de la verdad.

    We find a further class of exact solutions to the Lighthill Whitham Richards Payne (LWRP) traffic flow equations. As before, using two consecutive Lagrangian transformations, a linearization is achieved. Next, depending on the initial density, we either obtain exact formulae for the dependence of the car density and velocity on $x,t$, or else, failing that, the same result in a parametric representation. The calculation always involves two possible factorizations of a consistency condition. Both must be considered. In physical terms, the lineup usually separates into two offshoots at different velocities. Each velocity soon becomes uniform. This outcome in many ways resembles not only 2013 $J. Phys.$ A: $Math.

  11. Sexual modernity in the works of Richard von Krafft-Ebing and Albert Moll.

    Science.gov (United States)

    Oosterhuis, Harry

    2012-04-01

    The modern notion of sexuality took shape at the end of the nineteenth century, especially in the works of Richard von Krafft-Ebing and Albert Moll. This modernisation of sexuality was closely linked to the recognition of sexual diversity, as it was articulated in the medical-psychiatric understanding of what, at that time, was labelled as perversion. From around 1870, psychiatrists shifted the focus from immoral acts, a temporary deviation of the norm, to an innate morbid condition. In the late nineteenth century, several psychiatrists, collecting and publishing more and more case histories, classified and explained the wide range of deviant sexual behaviours they traced. The emergence of medical sexology meant that perversions could be diagnosed and discussed. Against this background both Krafft-Ebing and Moll articulated a new perspective, not only on perversion, but also on sexuality in general. Krafft-Ebing initiated and Moll elaborated a shift from a psychiatric perspective in which deviant sexuality was explained as a derived, episodic and more or less singular symptom of a more fundamental mental disorder, to a consideration of perversion as an integral part of a more general, autonomous and continuous sexual instinct. Before Sigmund Freud and others had expressed similar views, it was primarily through the writings of Krafft-Ebing and Moll that a new understanding of human sexuality emerged.

    U.S. President Richard Milhous Nixon, aboard the U.S.S. Hornet aircraft carrier, used binoculars to watch the Apollo 11 Lunar Mission recovery. The recovery operation took place in the Pacific Ocean where Navy para-rescue men recovered the capsule housing the 3-man Apollo 11 crew. The crew was airlifted to safety aboard the U.S.S. Hornet, where they were quartered in a Mobile Quarantine Facility (MQF) for 21 days post mission. The Apollo 11 mission, the first manned lunar mission, launched from the Kennedy Space Center, Florida via the Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. The Saturn V vehicle was developed by the Marshall Space Flight Center (MSFC) under the direction of Dr. Wernher von Braun. Aboard were Neil A. Armstrong, commander; Michael Collins, Command Module (CM) pilot; and Edwin E. Aldrin Jr., Lunar Module (LM) pilot. The CM, piloted by Michael Collins remained in a parking orbit around the Moon while the LM, named 'Eagle'', carrying astronauts Neil Armstrong and Edwin Aldrin, landed on the Moon. Armstrong was the first human to ever stand on the lunar surface, followed by Edwin (Buzz) Aldrin. During 2½ hours of surface exploration, the crew collected 47 pounds of lunar surface material for analysis back on Earth. With the success of Apollo 11, the national objective to land men on the Moon and return them safely to Earth had been accomplished.

The Saturn V vehicle was developed by the Marshall Space Flight Center (MSFC) under the direction of Dr. Wernher von Braun. Aboard were Neil A. Armstrong, commander; Michael Collins, Command Module (CM) pilot; and Edwin E. Aldrin Jr., Lunar Module (LM) pilot. The CM, piloted by Michael Collins remained in a parking orbit around the Moon while the LM, named 'Eagle'', carrying astronauts Neil Armstrong and Edwin Aldrin, landed on the Moon. Armstrong was the first human to ever stand on the lunar surface, followed by Edwin (Buzz) Aldrin. During 2½ hours of surface exploration, the crew collected 47 pounds of lunar surface material for analysis back on Earth. With the success of Apollo 11, the national objective to land men on the Moon and return them safely to Earth had been accomplished.

    Full Text Available American evangelicalism has often been punctuated by dual commitments to the United States and to God. Those commitments were strongest within politically conservative evangelicalism. Though representing a solid majority among professing evangelicals, conservatives could not speak for the movement as a whole. Politically progressive evangelicals, beginning in the 1960s, formed a dissenting opinion of the post-World War II revival of Christian nationalism. They dared to challenge American action abroad, noticeably during the Vietnam War. Their critique of Christian nationalism and conservative evangelicals’ close ties to the Republican Party led them to seek refuge in either progressive policies or the Democratic Party. A third, underexplored subgroup of evangelicalism rooted in reformed theology becomes important to consider in this regard. These reformed evangelicals sought to contextualize nationalism in biblical rather than partisan or political terms. This goal is championed well by Richard Mouw, resulting in a nuanced look at evangelical Christians’ difficult dual role as both citizens of the Kingdom of God and the United States.

  17. Richard Dadd: the patient, the artist, and the "face of madness".

    2015-01-01

    Richard Dadd (1817-1886) was a well-known Victorian artist who murdered his father, compelled by the delusion that a demonic force possessed his father's body. He was one of the first to bypass execution by reason of insanity and spent the remainder of his life in the Bethlem and Broadmoor asylums. Dadd is rare both as a patient and an artist because he left behind nearly a 40-year record of artwork and journals, which constitute a unique medical and psychiatric resource at a time when the ideas on the relationship of facial expression and madness were changing. Sir Charles Bell's (1774-1842) widely accepted views that the "face of madness" is bestial and anatomically distinctive were being challenged by such physicians as Sir Alexander Morison (1779-1866), who was also Dadd's own "alienist" (i.e., psychiatrist). The purpose of this article is to explore the nature and extent of the influence of Bell and Morison on Dadd, which has not been brought out in the existing studies. By a comparative analysis, it will be shown that Dadd may have conveyed a different view in his works that foreshadows subsequent developments that are closer to a modern understanding.

    We find a further class of exact solutions to the Lighthill-Whitham- Richards-Payne (LWRP) traffic flow equations. As before, using two consecutive Lagrangian transformations, a linearization is achieved. Next, depending on the initial density, we either obtain exact formulae for the dependence of the car density and velocity on x,t, or else, failing that, the same result in a parametric representation. The calculation always involves two possible factorizations of a consistency condition. Both must be considered. In physical terms, the lineup usually separates into two offshoots at different velocities. Each velocity soon becomes uniform. This outcome in many ways resembles not only that of Rowlands et al (2013 J. Phys. A: Math. Theor. 46 365202 (part I)) but also the two-soliton solution to the Korteweg-de Vries equation. This paper can be read independently of part I. This explains unavoidable repetitions. Possible uses of both papers in checking numerical codes are indicated. Since LWRP, numerous more elaborate models, including multiple lanes, traffic jams, tollgates, etc, abound in the literature. However, we present an exact solution. These are few and far between, other than found by inverse scattering. The literature for various models, including ours, is given. The methods used here and in part I may be useful in solving other problems, such as shallow water flow.

  19. Unreliability and the Animal Narrator in Richard Adams’s The Plague Dogs

    Anja Höing

    2017-03-01

    Full Text Available Richard Adams’s talking animal story The Plague Dogs (1978, with its deeply genre-atypical mode of narration, offers a multiplicity of avenues to explore the literary animal as animal. The story draws much of its power from the psychological complexity and related unreliability of both canine narrators, two research lab escapees gone feral. Both the terrier Snitter and the black mongrel Rowf are mentally ill and experience a highly subjective, part-fantastic world. In episodes of zero focalization, a sarcastic voice comments on the plot from the off, aggressively attacking a thoroughly anthropocentric superstructure the protagonists themselves are oblivious of, and presenting all that is normally constructed as “rational” in the implied reader’s world as a carnivalesque farce. Combining these equally unreliable narratives, The Plague Dogs creates a unique mixture of what Phelan (2007 calls “estranging” and “bonding” unreliability and brings to light the devastating consequences of anthropocentrism. The Plague Dogs not only defamiliarizes a genre usually committed to conventional means of storytelling, but the dominant Western conception of the status of animals in the world, showing that once we start to read the animal as animal, this sets into motion an avalanche of other concepts in need of re-reading, among them the very ones making up the fundamental pillars of Western societies’ anthropocentric self-conception.

  20. Who invented the dichotomous key? Richard Waller's watercolors of the herbs of Britain.

    2011-12-01

    On 27 March 1689, Richard Waller, Fellow and Secretary of the Royal Society presented his "Tables of the English Herbs reduced to such an order, as to find the name of them by their external figures and shapes" to his assembled colleagues at a meeting of the Royal Society. These tables were developed for the novice by being color images, composed in pencil and watercolor, of selected plants and their distinguishing characteristics. The botanical watercolors for the tables are now a Turning-the-Pages document online on the website of the Royal Society. However, for the past 320 years, the scientific context for the creation of these outstanding botanical watercolors has remained obscure. These tables were developed by Waller as an image-based dichotomous key, pre-dating by almost 100 years the text-based dichotomous keys in the first edition of Flora Française (1778) by Jean Baptiste Lamarck, who is generally given priority for the development of the dichotomous key. How these large folio images were arranged to illustrate a dichotomous key is unknown, but an arrangement based on Waller's description is illustrated here as leaf-ordering for the separate hierarchical clusters (tables). Although only 24 species of watercolored dicot herbs out of a total of 65 in the set of watercolors (the others being monocots) are used in these tables, they are a "proof of concept", serving as models upon which a method is based, that of using a key composed of dichotomous choices for aiding identification.

    2010-09-01

    Full Text Available Etika tak dapat dipungkiri adalah isu bagi setiap bidang ilmu. Pertanyaan etika bukanlah pertanyaan tentang kewajiban satu-dua orang tertentu atau satu-dua bidang spesifik saja melainkan sebagaimana telah dirumuskan dengan tajam oleh Imannuel Kant dalam Critique of Practical Reason adalah pertanyaan segenap manusia sebagai mahluk yang berpikir dan punya kebebasan memilih tentang: apa yang seharusnya aku lakukan. Dari definisi Kant kita dapat menarik kesimpulan bahwa jika saja manusia tidak mampu berpikir dan tidak bebas menentukan tindakannya, maka mustahil diharapkan tanggung jawab moral darinya. Meskipun demikian, tulisan kecil ini tidak bermaksud untuk memberikan paparan etika secara menyeluruh dan historis, melainkan sekadar sketsa tentang diskursus etika kontemporer yang diwakili dua sosok pemikir ternamanya: Jrgen Habermas dari tradisi Teori Kritis Mazhab Frankfurt, dan Richard Rorty dari kubu Neo- Pragmatisme. Habermas mengajukan etika diskursus dan Rorty mengajukan konsep etika lewat sosok manusia ironis-liberal-nya. Diharapkan sidang pembaca dapat sedikit mencicipi problematik etika yang tak terhindarkan karena setiap posisi etika selalu theory laden, dan teori itu sendiri berciri historis (dapat ditelusuri ciri-ciri, asal-usul dan konteks historis mazhab-mazhab yang melatar-belakanginya. Maka dari itu etika adalah refleksi yang belum pernah selesai meskipun sudah dimulai sejak 2500 tahun yang lalu. Malah etika mengundang kita dari ilmu-ilmu spesifik untuk masuk ke dalam diskursus general-nya yang mau tak mau berciri sedemikian all-encompassing, persis karena ia menyangkut manusia.

    2010-10-01

    Full Text Available Ethics without doubt is an issue in every scientific field. Questions on ethics are not merely questions on the responsibility of one or two specific individuals, but rather as what have been defined accurately by Immanuel Kant in Critique of Practical Reason – as question of all humanity as a thinking creature and the freedom of choice on, “what should I do”. From Kant’s definition, we may infer that if human can not think and not free in determining their choice, it would be almost impossible to hope for moral responsibility. However this article does not mean to give a full and historical description on ethics, but a sketch on discourse of contemporary ethics which is represented by two famous philosophers, Jürgen Habermas from the tradition of  Critical Theory from Frankfurt School, dan Richard Rorty with “Neo-Pragmatism”. Habermas proposes “discourse ethics” while Rorty proposes ethic concepts through his “liberal-ironists”. It is hoped that the assembly of readers may gain an insight of the unavoidable ethics problems since every ethical position must be theory laden and the theory itself has historical characteristics (the characteristics, origin and historical context of the schools behind it. Therefore ethics is a neverending reflection although it has been started from 2500 years ago. Ethics invites us from specific sciences to enter its general discourse which unavoidably all-encompassing in its nature.

    Full Text Available The core of this article presents a structural and thematic analysis of a novel The Sound  of One Hand Clapping (1979 written by a contemporary Australian novelist Richard Flanagan (1961-. The novel deals mainly with the life of a Slovene family, which immigrated to Australia in 1954. The story centres on the life of the heroine, Sonja Bulah, who finds herself at the end of the 1980ies in a severe mental crisis. Besides, the author of this article uses information about immigrants' life in Australia obtained from reports and sketches of a Slovene psychiatrist who treated immigrants in Melbourne. The author of this paper also calls the reader's attention to various literary allusions, which appear in the novel (e.g. Eugene O'Neill, John Keats, W. B. Yeats. It also appears that Flanagan was under a strong spiritual influence of the Indian philosopher Osho(= Bhagwan Shree Rajneshi and his meditations upon life as published in Osho's book bearing the same title as Flanagan's novel and which first appeared in 1981. The novel is particularly interesting for Slovene readers, because it uncovers the emotional and spiritual life of Slovene immigrants in Australia.

    Acid Leachable Trace Metal (ALTMs) concentrations in tourist beaches of Richards Bay, Kwazulu-Natal, South Africa were assessed. 53 surface sediment samples were collected from five different beaches (Kwambonambi Long Beach; Nhlabane Beach; Five Mile Beach; Alkanstrand Beach and Port Durnford Beach). The results of ALTMs (Fe, Mn, Cr, Cu, Ni, Co, Pb, Cd, Zn, As, Hg) suggest that they are enriched naturally and with some local industrial sources for (avg. in μgg(-1)) Fe (3530-7219), Mn (46-107.11), Cd (0.43-1.00) and Zn (48-103.98). Statistical results indicate that metal concentrations were from natural origin attributed to leaching, weathering process and industrial sources. Comparative studies of metal concentrations with sediment quality guidelines and ecotoxicological values indicate that there is no adverse biological effect. Enrichment factor and geoaccumulation indices results indicate moderate enhancement of Fe (Igeo class 1 in FMB), Cd (EF>50; Igeo classes 2-4) and Zn (Igeo classes 1 & 2).

    2001-01-01

    The Li-rich Zn-doped LiNbO3 (LN) crystals were grown by the Czochralski method. The structure of the crystals was measured by ultraviolet-visible absorption spectra. The results indicated that the Li-rich Zn-doped LN crystals had the same characteristics as the pure LN crystal. After Zn2+ entered into the lattice of Li-rich Zn-doped LN crystal, it replaced NbLi firstly. When there was no NbLi, Zn2+ replaced Li+ then. The second harmonic generation (SHG) property of Li-rich Zn-doped LiNbO3 crystal was measured. The results showed that the SHG conversation efficiency of Li-rich Zn-doped LiNbO3 crystals was higher than that of Zn-doped LiNbO3 crystals.

  10. An extension of the open-source porousMultiphaseFoam toolbox dedicated to groundwater flows solving the Richards' equation

    Horgue, Pierre; Guibert, Romain; Debenest, Gérald

    2015-01-01

    In this note, the existing porousMultiphaseFoam toolbox, developed initially for any two-phase flow in porous media is extended to the specific case of the Richards' equation which neglect the pressure gradient of the non-wetting phase. This model is typically used for saturated and unsaturated groundwater flows. A Picard's algorithm is implemented to linearize and solve the Richards' equation developed in the pressure head based form. This new solver of the porousMultiphaseFoam toolbox is named groundwaterFoam. The validation of thesolver is achieved by a comparison between numerical simulations and results obtained from the literature. Finally, a parallel efficiency test is performed on a large unstructured mesh and exhibits a super-linear behavior as observed for the other solvers of the toolbox.

  11. A non-local Richards equation to model infiltration into highly heterogeneous media under macroscopic non-equilibrium pressure conditions

    Neuweiler, I.; Dentz, M.; Erdal, D.

    2012-04-01

    Infiltration into dry strongly heterogeneous media, such as fractured rocks, can often not be modelled by a standard Richards equation with homogeneous parameters, as the averaged water content is not in equilibrium with the averaged pressure. Often, double continua approaches are used for such cases. We describe infiltration into strongly heterogeneous media by a Richards model for the mobile domain, that is characterized by a memory kernel that encodes the local mass transfer dynamics as well as the geometry of the immobile zone. This approach is based on the assumption that capillary flow can be approximated as diffusion. We demonstrate that this approximation is in many cases justified. Comparison of the model predictions to the results of numerical simulations of infiltration into vertically layered media shows that the non-local approach describes well non-equilibrium effects due to mass transfer between high and low conductivity zones.

  12. A new data assimilation technique based on ensemble Kalman filter and Brownian bridges: An application to Richards' equation

    2016-11-01

    In this paper a new data assimilation technique is proposed which is based on the ensemble Kalman filter (EnKF). Such a technique will be effective if few observations of a dynamical system are available and a large model error occurs. The idea is to acquire a fine grid of synthetic observations in two steps: (1) first we interpolate the real observations with suitable polynomial curves; (2) then we estimate the relative measurement errors by means of Brownian bridges. This technique has been tested on the Richards' equation, which governs the water flow in unsaturated soils, where a large model error has been introduced by solving the Richards' equation by means of an explicit numerical scheme. The application of this technique to some synthetic experiments has shown improvements with respect to the classical ensemble Kalman filter, in particular for problems with a large model error.

    Between 2004 and 2012, the author wrote two biographies, the first of 20th century civil servant Ernest Gowers and the second of his father the Victorian neurologist William Richard Gowers. This article describes the author's experience conducting the research for two biographies at a time when the research tools available were rapidly shifting from paper-based to digital records. Technological aids have made the preliminary research of historians easier, but they have not taken the place of hard copy archive-based research. While the paper will focus primarily on the biography of William Richard Gowers, the author describes the research methods she employed to help reveal the personalities, strengths and weaknesses of both men, each of whom left his own intellectual legacy.

  17. A Few Remarks on the Poetics of Turbulence in Richard Powers’ Operation Wandering Soul

    Jean-Yves Pellegrin

    2010-02-01

    Full Text Available Dans le roman de Richard Powers Operation Wandering Soul, la linéarité conventionnelle du récit cède le pas à une forme de discontinuité et de circularité qui évoque le mouvement imprévisible d’une turbulence. On propose de montrer ici que cette turbulence met en œuvre une nouvelle manière d’écrire et de lire les récits. Dans le roman, la turbulence apparaît toujours sous l’aspect d’une force désorganisatrice qu’il faut maîtriser, un bruit qui doit être supprimé. Cet impératif, témoin des aspirations du récit au sens et à la clôture, peut se concevoir comme l’indice de la manière dont l’ordre narratif s’efforce de soumettre toute turbulence en dissimulant son chaos sous une linéarité de façade et des dénouements postiches. Cette activité transforme le récit (et le type de lecture qu’elle induit en une sorte d’eschatologie dont Operation Wandering Soul dénonce le mensonge et la fuite en avant. Pour en combattre les effets néfastes, le roman s’emploie à perturber l’ordre narratif et à bousculer nos habitudes de lecture ; il se fait texte turbulent en conformant sa structure la plus intime à celle des systèmes non linéaires.In Richard Powers’ Operation Wandering Soul, the conventional linearity of narrative gives way to a type of discontinuity and circularity that is reminiscent of the unpredictable movement of turbulent flows. This paper suggests that such turbulence enacts a new way of writing and reading narrative. Turbulence is always described in the novel as a disruptive force that must be checked or a noise that must be silenced. This imperative, which testifies to narrative’s desire for closure and meaning, may be construed as an index of the way narrative order attempts to subdue all turbulence by covering up its proliferating chaos with perfunctory linearity and cosmetic endings. Such activity turns narrative—and the type of reading it encourages—into some kind of

  19. Richard von Krafft-Ebing's views on the etiology of major psychiatric illness.

    Science.gov (United States)

    Engstrom, E J; Kendler, K S

    2013-07-01

    While best known in the anglophonic world for his work on sexual deviations and his advocacy for degeneration theory, Richard Krafft-Ebing (RKE) (1840-1902) was a major figure in late-19th century European psychiatry and author of the most widely read German psychiatric textbook of that era. With the goal of (re-)introducing his work to an anglophonic audience, we review and provide an historical context for RKE's etiologic theory of major psychiatric illness. RKE saw psychiatric disorders as multifactorial, arising from two sets of etiologic factors: predisposing and exciting. Exciting causes were either psychological or physical, while predisposing causes were either general (e.g. sex, occupation, age) or individual-specific. Three major individual-specific risk factors were of particular importance: heredity, personality and education/rearing. Hereditary factors were typically the most important but were usually non-specific in their effect with the forms of psychiatric illness often differing in close relatives. He emphasized the importance of the 'neuropathic personality,' which rendered affected individuals sensitive to the pathogenic effects of various exciting influences. Poor rearing could also substantially increase risk for major mental illness. RKE saw the influences of hereditary and rearing factors on psychiatric illness as often mediated through a neuropathic personality. While RKE believed in degeneration theory and emphasized the potential etiologic importance of masturbation in psychiatric illness, his clinical writings were otherwise characterized by a broad-minded and sensible approach that lacked the narrowness of the strongly brain-based or psychoanalytic psychiatric schools which were very influential during and shortly after his life.

  20. Morrow, Reiff, Receive 2013 Space Physics and Aeronomy Richard Carrington Awards: Response

    It is a special privilege to receive this award honoring Richard Carrington's discovery of what we now call space weather. It is particularly appropriate that this award also recognizes Cherilynn Morrow, who 20 years ago made a presentation to the Space Science Advisory Committee on Jeff Rosendhal's idea of mission-based E/PO. We worked together, bringing that idea to the successful, but threatened, network it is today. For me, learning and teaching go hand in hand—as we publish our findings for our peers, we should also repay the public investment in our research with accurate, understandable results. My interest in space science was sparked by a father-daughter course in astronomy sponsored by the Brownies at the Oklahoma City Planetarium and kindled by the Bell Labs production The Strange Case of the Cosmic Rays directed by Frank Capra. Knowing that planetarium shows and educational movies can change lives, I have devoted a large portion of my last 25 years to creating software, shows, and portable planetariums to inspire and engage youth. This has not been a one-person effort, of course. My work Cherilynn Ann Morrow would have been impossible without the collaboration of Carolyn Sumners, vice president of the Houston Museum of Natural Science. Our museum kiosk and planetarium control software would not have happened without the skill and perseverance of my chief programmer, Colin Law. Jim Burch has been first a mentor and then a colleague on both the research and outreach sides of my career. I share this honor with a long line of highly talented students and postdocs who have contributed science content and outreach efforts. Most importantly, without the support of my husband, Tom Hill, I would not have had the time and freedom to build an educational network while continuing research and raising a family. I thank AGU for bestowing this honor.

  1. An experimental 'Life' for an experimental life: Richard Waller's biography of Robert Hooke (1705).

    Moxham, Noah

    2016-03-01

    Richard Waller's 'Life of Dr Robert Hooke', prefixed to his edition of Hooke's Posthumous Works (1705), is an important source for the life of one of the most eminent members of the early Royal Society. It also has the distinction of being one of the earliest biographies of a man of science to be published in English. I argue that it is in fact the first biography to embrace the subject's natural-philosophical work as the centre of his life, and I investigate Waller's reasons for adopting this strategy and his struggle with the problem of how to represent an early experimental philosopher in print. I suggest that Waller eschews the 'Christian philosopher' tradition of contemporary biography - partly because of the unusually diverse and fragmentary nature of Hooke's intellectual output - and draws instead upon the structure of the Royal Society's archive as a means of organizing and understanding Hooke's life. The most quoted phrase from Waller's biography is that Hooke became 'to a crime close and reserved' in later life; this essay argues that Waller's biographical sketch was fashioned in order to undo the effects of that reserve. In modelling his approach very closely on the structure of the society's records he was principally concerned with making Hooke's work and biography accessible, intelligible and useful to the fellowship in a context familiar to them, a context which had provided the institutional framework for most of Hooke's adult life. I argue that Waller's 'Life' was also intended to make the largest claims for Hooke's intellectual standing that the author dared in the context of the enmity between Hooke and Isaac Newton once the latter became president of the Royal Society. However, I also adduce fresh manuscript evidence that Waller actually compiled, but did not publish, a defence of Hooke's claim to have discovered the inverse square law of gravity, allowing us to glimpse a much more assertive biography of Hooke than the published version.

  2. Timothy Leary, Richard Alpert (Ram Dass) and the changing definition of psilocybin.

    2010-05-01

    This research focuses on the events leading to the 1968 U.S. federal prohibition of psilocybin. It is a study of duelling moral entrepreneurs-Timothy Leary and Richard Alpert vs. the Harvard University Administration. The goal is to show how the primary active compound in an ostensibly harmless fungus (the psilocybin mushroom) became controversial in less than a decade. We used books, newspapers, magazine articles and previously unpublished materials (including documents from the Harvard Archives) to analyze Leary and Alpert's lives and careers through the early 1970s. The prohibition of psilocybin in the U.S. was largely a product of Leary and Alpert's involvement in the "Harvard drug scandal" and their transformation from Harvard professors to countercultural icons. They tested the substance on a variety of human subjects and in doing so piqued the interest of Harvard undergraduates while drawing condemnation from other faculty and Harvard administrators. This case is theoretically interesting because unlike most illegal drugs, psilocybin was never linked to a threatening minority group, but to some of the nation's most privileged youth. The Harvard administrators were not really moral entrepreneurs but Leary and Alpert clearly were. Although they were far from being prohibitionists, they were self-righteous crusaders on different but equally holy missions for the good of young and minority Americans. Ironically, due to their successes the possession of psilocybin was criminalized under United States federal law in 1968 (Pub. L. No. 90-639, Stat. 1361 1968 and Boire, 2002). This case study demonstrates that crusaders can be successful in changing culture even when laws are passed in futile attempts to control their behaviour, just as Leary predicted.

  3. Sufi, Christian or Buddhist? Richard Francis Burton’s “Parameters of Belief”

    Directory of Open Access Journals (Sweden)

    2013-09-01

    Full Text Available Richard Burton has been interpreted and misinterpreted by literary critics as eminent as Edward Said and Louisa Pratt as well as by others such as Rana Kabbani and Reina Lewis. Biographers like Fawn Brody, Edward Rice, Mary Lovell and Jon Godsall have also had their say. Burton has been variously described as imperialist, sexist, gay, obssessed with pornography, racist, plagiarist, sexual libertine, scatologist, expert sociologist, profoundly deceitful and impotent. In spite of this negative press, interest in Burton is always high as his life and times are relevant to many scholars interested in the 19th century origins of modern thought and postcolonial ideas. In this paper presentation I will attempt to get beyond the confused and contradictory portrayals of Burton over the last 50 or so years by looking in some detail at Burton’s two long poems: Stone Talk and The Kasidah. In these works, published 15 years apart, Burton writes under pseudonyms and, as I will argue, is able to express many of his deepest beliefs, especially in The Kasidah where he is playing the part of Hadji Abu Al Yezid, a Sufi like-wise man who possesses some startling similarities to Burton himself. What emerges from this close examination of the texts is a sensitive relativist who, while adhering to the scientific method in all his practical dealings, is yet able to consider the possibility that everything we see around us and all our experience of the world might be, finally, nothing more than Maya and illusion.

  4. The Effect of Richard Wagner's Music and Beliefs on Hitler's Ideology

    2016-09-01

    Full Text Available The Holocaust will always be remembered as one of the most horrific and evil events in all of history. One question that has been so pervasive in regards to this historical event is the question of why. Why exactly did Hitler massacre the Jewish people? Why did he come to the conclusion that the Jews were somehow lesser than him, and that it was okay to kill them? What and who were his influences and how did they help form Hitler’s opinions leading up to the Holocaust? Although more than one situation or person influenced Hitler, I believe that one man in particular really helped contribute to Hitler’s ideas, especially about the Jewish people. This man is the famous musician Richard Wagner. While musicologists admit that Wagner was a musical genius, one aspect of his career that is hard to ignore is his strong antisemitism. In addition to speaking about his hatred for the Jews, he also wrote about it in his music, making it hard to glance over. Hitler had been close to the Wagner family, and had an obsessive, cult-like infatuation with Wagner’s music beginning in his childhood. This infatuation with Wagner’s music and his closeness to his later family helped facilitate and solidify his negative views about the Jewish people. In this paper I will explore the antisemitism that is within Wagner’s music and writing, and then I will discuss how Wagner’s antisemitism helped inform, influence, and shape Hitler’s ideas, indirectly assisting in the propagation of the Holocaust.

    Body sway while maintaining an upright quiet stance reflects an active process of balance based on the integration of visual, vestibular, somatosensory, and proprioceptive inputs. Richard Serra's Promenade sculpture featured in the 2008 Monumenta exhibition at the Grand Palais in Paris, France is herein hypothesized to have stimulated the body's vertical and longitudinal axes as it showcased five monumental rectangular solids pitched at a 1.69(°) angle. Using computerized dynamic posturography we measured the body sway of 23 visitors when fixating a cross, or when observing the artwork (fixating it or actively exploring it with eye movements) before and after walking around and alongside the sculpture (i.e., before and after a promenade). A first fixation at the sculpture increased medio-lateral stability (in terms of spectral power of body sway). Eye movement exploration in the depth of the sculpture increased antero-posterior stability [in terms of spectral power and canceling time (CT) of body sway] at the expense of medio-lateral stability (in terms of CT). Moreover, a medio-lateral instability associated with eye movement exploration before the promenade (in terms of body sway sensu stricto) was canceled after the promenade. Finally, the overall medio-lateral stability (in terms of spectral power) increased after the promenade. Fourteen additional visitors were asked to stand in a dark room and adjust a luminous line to what they considered to be the earth-vertical axis. The promenade executed within the sculpted environment afforded by Serra's monumental statuary works resulted in significantly improved performances on the subjective visual vertical test. We attribute these effects to the sculpted environment provided by the exhibition which may have acted as a kind of physiologic "training ground" thereby improving the visitors' overall sense of visual perspective, equilibrium, and gravity.

  6. Richard Doll and Alice Stewart: reputation and the shaping of scientific "truth".

    As the world watched the Fukushima reactors release radionuclides into the ocean and atmosphere, the warnings of Dr. Alice Stewart about radiation risk and the reassurances of Sir Richard Doll assumed renewed relevance. Doll and Stewart, pioneer cancer epidemiologists who made major contributions in the 1950s-he by demonstrating the link between lung cancer and smoking, she by discovering that fetal X-rays double the chance of a childhood cancer-were locked into opposition about low-dose radiation risk. When she went public with the discovery that radiation at a fraction of the dose "known" to be dangerous could kill a child, her reputation plummeted, whereas Doll, foremost among her detractors, was knighted and lauded as "the world's most distinguished medical epidemiologist" for his work. Their lives and careers, so closely intertwined, took contrary courses, he becoming "more of the establishment" (as he said), while she became more oppositional. When it was discovered, after his death, that he'd been taking large sums of money from industries whose chemicals he was clearing of cancer risk, his reputation remained unscathed; it is now enshrined in the "Authorized Biography" (2009) commissioned by the Wellcome Institute, along with Doll's denigration of Stewart as an "embittered" woman and biased scientist. Stewart lived long enough to see radiation science move her way, to see international committees affirm, in the 1990s, that there is no threshold beneath which radiation ceases to be dangerous; recent evidence from Chernobyl is bearing out her warnings. But a look at the making and breaking of these reputations reveals the power of status, position, and image to shape scientific "knowledge" and social policy.

  8. An Enlightenment proposal for music therapy: Richard Brocklesby on music, spirit, and the passions.

    2015-01-01

    In 1749, the London physician Richard Brocklesby (1722-1797) published his Reflections on Antient [sic] and Modern Musick, an essay that not only sought to compare these practices in terms of their effects, but also to gather evidence supporting the use of music in treating mania and other mental diseases. As might be expected, Brocklesby's discussion of music therapy has already received attention by authors looking back to the origins of this practice, not least because he offers an account of a successful musical cure that took place in his own time (Rorke, 2001). My chapter, however, seeks to broaden the discussion of the Reflections, in order to show how Brocklesby's projected musical cures fit into his larger worldview, one that was influenced as much by Plato and other ancient philosophers as it was by modern thinkers such as Isaac Newton and his followers. Brocklesby's argument was essentially that music acted as a link between the mind and body and therefore could restore their intrinsic harmony, a connection that was mediated by the animal spirits, which also served as the vehicle of the passions. The movements and proportions of music could arouse or quell the passions by their effect on these (imaginary) spirits, which flowed through the nerves and brain and acted as the agent for the mind or soul. I show how his account of music in antiquity led him to reflect on the way that music was perceived and responded to in his own time, both as a stimulus to mental and bodily action, and as a source of esthetic pleasure through the cultivation of musical taste.

  9. From the Bright Future of the Nation to the Dark Future of Mankind: Jókai and Karinthy in Hungarian Utopian Tradition

    2016-01-01

    Full Text Available After defining utopianism Czigányik gives a brief introduction to Hungarian utopian literature. While he discusses Tariménes utazása [‘The Voyage of Tariménes’], written by György Bessenyei in 1804, the utopian scenes of Imre Madách’s Az ember tragédiája [‘The Tragedy of Man’, 1862] and Frigyes Karinthy’s short utopian piece, Utazás Faremidoba [‘Voyage to Faremido’, 1916], the bulk of the paper deals with Mór Jókai’s monumental novel, A jövő század regénye, [‘The Novel of the Century to Come’, 1872]. Jókai, who had taken an active part in the 1848 uprising, depicts in this novel a future world of an imaginary twentieth century, where Hungary has primacy within the Habsburg empire (with the emperor king being Árpád Habsburg and the invention of the airplane (by a Hungarian brings lasting peace, stability and prosperity to the world. Besides introducing the Hungarian utopian tradition, the paper will reflect upon the role of individuals in imagined societies and how an agency-centered narrative overwrites the essentially structuralist view of history, that usually permeates utopias.

  10. A Chinese herbal decoction, reformulated from Kai-Xin-San, relieves the depression-like symptoms in stressed rats and induces neurogenesis in cultured neurons

    Kai-Xin-San (KXS), a Chinese herbal decoction for anti-depression, is a combination of paired-herbs, i.e. Ginseng Radix et Rhizoma (GR)-Polygalae Radix (PR) and Acori Tatarinowii Rhizoma (ATR)-Poria (PO). The make-up of the paired-herbs has been commonly revised according to syndrome differentiation and treatment variation of individual. Currently, an optimized KXS (KXS2012) was prepared by functional screening different combination of GR-PR and ATR-PO. The aim of this study was to verify the effect and underlying mechanism of KXS2012 against depression in chronic mild stress (CMS)-induced depressive rats and in primary cultures of neurons and astrocytes. In rat model, the CMS-induced depressive symptoms were markedly alleviated by the treatment with KXS2012. The CMS-suppressed neurotransmitter amounts were restored in the presence of KXS2012. And the expressions of neurotropic factors and its corresponding receptors were increased under KXS2012 administration. In cultured neurons, application of KXS2012 could promote neurogenesis by inducing the expression of synaptotagmin and dendritic spine density. Moreover, application of KXS2012 in cultured astrocytes, or in H2O2-stressed astrocytes, induced the expressions of neurotrophic factors: the increase might be associated with the modification of Erk1/2 and CREB phosphorylation. Our current results fully support the therapeutic efficacy of KXS2012 against depression in cell and animal models. PMID:27444820

    Full Text Available Kai-xin-san (KXS, a Chinese herbal decoction being prescribed by Sun Simiao in Beiji Qianjin Yaofang about 1400 years ago, contains Ginseng Radix et Rhizoma, Polygalae Radix, Acori tatarinowii Rhizoma, and Poria. KXS has been used to treat stress-related psychiatric disease with the symptoms of depression and forgetfulness in ancient China until today. However, the mechanism of its antidepression action is still unknown. Here, the chronic mild-stress-(CMS- induced depressive rats were applied in exploring the action mechanisms of KXS treatment. Daily intragastric administration of KXS for four weeks significantly alleviated the CMS-induced depressive symptoms displayed by enhanced sucrose consumption. In addition, the expressions of those molecular bio-markers relating to depression in rat brains were altered by the treatment of KXS. These KXS-regulated brain biomarkers included: (i the levels of dopamine, norepinephrine, and serotonin (ii the transcript levels of proteins relating to neurotransmitter metabolism; (iii the transcript levels of neurotrophic factors and their receptors. The results suggested that the anti-depressant-like action of KXS might be mediated by an increase of neurotransmitters and expression of neurotrophic factors and its corresponding receptors in the brain. Thus, KXS could serve as alternative medicine, or health food supplement, for patients suffering from depression.

    This investigation treats quantum-mechanically the ion- atom collisions and computes the transport coefficients, such as the coefficients of mobility and diffusion. For the case of lithium, the calculations start by determining the gerade and ungerade potential curves through which ionic lithium approaches ground lithium. Then, by considering the isotopic effects and nuclear spins, the elastic and charge-transfer cross sections are calculated for the case of 6Li+and7Li+ colliding with 6Li. Finally, the temperature-dependent diffusion and mobility coefficients are analyzed, and the results are contrasted with those obtained from literature. The main results of this work have been recently published in. This work has been realized within the frames of the CNEPRU Project D01120110036 of the Algerian Ministry of Higher Education.

    Water storage in the unsaturated zone is controlled by capillary forces which increase nonlinearly with decreasing pore size, because water acts as a wetting fluid in soil. The standard approach to represent capillary and gravity controlled soil water dynamics is the Darcy-Richards equation in combination with suitable soil water characteristics. This continuum model essentially assumes capillarity controlled diffusive fluxes to dominate soil water dynamics under local thermodynamic equilibrium conditions. Today we know that the assumptions of local equilibrium conditions e.g. and a mainly diffusive flow are often not appropriate, particularly during rainfall events in structured soils. Rapid or preferential flow imply a strong local disequilibrium and imperfect mixing between a fast fraction of soil water, traveling in interconnected coarse pores or non-capillary macropores, and the slower diffusive flow in finer fractions of the pore space. Although various concepts have been proposed to overcome the inability of the Darcy - Richards concept to cope with not-well mixed preferential flow, we still lack an approach that is commonly accepted. Notwithstanding the listed short comings, one should not mistake the limitations of the Richards equation with non-importance of capillary forces in soil. Without capillarity infiltrating rainfall would drain into groundwater bodies, leaving an empty soil as the local equilibrium state - there would be no soil water dynamics at all, probably even no terrestrial vegetation without capillary forces. Better alternatives for the Darcy-Richards approach are thus highly desirable, as long they preserve the grain of "truth" about capillarity as first order control. Here we propose such an alternative approach to simulate soil moisture dynamics in a stochastic and yet physical way. Soil water is represented by particles of constant mass, which travel according to the Itô form of the Fokker Planck equation. The model concept builds on

    DSC (Differential Scanning Calorimetry) study has been made on the reactions of metallic Li or LiC6 with organic solvents for lithium ion battery. Ethylene carbonate (EC) more easily reacts with metallic Li and LiC6 than propylene carbonate (PC). This may be because formation of lithium alkyl carbonate is more difficult for PC than EC. On the other hand, diethyl carbonate (DEC), ethyl methyl carbonate (EMC) and dimethyl carbonate (DMC) react with Li in the same manner. Reactions of Li and LiC6 with organic solvents have been discussed based on the results of quantum calculation.

    Full Text Available   This article attempts an exploration of Michel Henry’s I Am the Truth and Richard Kearney’s The God Who May Be, as each appropriate the Husserlian critique of Kantian epistemology. Although Henry and Kearney both develop a Christian theology rooted in this Husserlian inheritance, their explication of the truths Christianity asserts is strikingly different. It is the assertion of this essay that this difference is primarily a textual one; or, to put it another way, it is conditioned first by their scriptural gaze.Cet article se propose de reprendre le contenu de Michel Henry, C’est moi, la vérité et Richard Kearney The God Who May Be, dans lesquels les auteurs analysent la critique husserlienne de l’épistémologie kantienne. Bien que Henry et Kearney tous les deux développent une théologie chrétienne enracinée dans cet héritage husserlien, leur explication des vérités affirmées du Christianisme est très différente. Pour nous, la différence entre eux est de type textuel, c’est à dire qu’elle dépend de l’analyse qu’ils font de la Sainte Écriture.Questo articolo si propone di riprendere il contenuto dei testi Io sono la verità di Michel Henry e The God Who May Be di Richard Kearney, nei quali i rispettivi autori analizzano la critica husserliana dell'epistemologia di Kant.

  14. A Numerical Method for the Estimation of Distributed Hydraulic Conductivity Using Richards Equation

    Cockett, R.; Haber, E.

    2013-12-01

    Characterizing groundwater flow in the vadose zone has many important and practical applications in near surface hydrogeology. The spatial estimation of the hydraulic conductivity function, which is the regulator of unsaturated groundwater flow, is an critical step in any hydrogeologic site characterization. However, this estimation is difficult and simplifications are consistently used to avert these conceptual and computational difficulties. Comprehensive time-lapse data of in situ saturations, or proxies of saturation from geophysical methods, are increasingly available. Using these large data sets appropriately, and maximizing the utility of the data to recover estimates of heterogeneous hydraulic conductivity, requires innovative numerical methods. This inverse problem has been approached in many different ways in the literature from stochastic methods to various gradient based methods. However, the way in which the computational complexity of the inverse method scales becomes important as problem size increases; as computational memory and time often become the bottleneck of solving the inverse problem when the problem is solved for heterogeneous hydraulic conductivity in two- and particularly in three-dimensions. For the inverse problem involving Richards equation, some version of a Gauss-Newton method (e.g. Levenberg-Marquardt) with a direct calculation of the sensitivity matrix is commonly used. However, while these approaches allow to deal with moderate scale problems they have one major drawback: the sensitivity matrix is a large dense matrix and its computation requires dense linear algebra and, for large scale problems, a non-trivial amount of storage. Furthermore, previous work use either numerical or automatic differentiation in order to compute the sensitivity matrix and this can generate inaccuracies in its computation and tarry convergence of the optimization algorithm. We suggest a modern numerical method that allows for the solution of the

    The presence of the lithium-6 isotope in some metal-poor stars is a matter of surprise because of the high values observed. Non-standard models of Big Bang nucleosynthesis and pre-Galactic cosmic ray fusion and spallation have been proposed to explain these values. However, the observations of this light isotope are challenging which may make some detections disputable. The goal was to determine 6Li/7Li for a sample of metal-poor stars; three of them have been previously studied and the remaining two are new for this type of study. The purpose was to increase, if possible, the number of lithium-6 detections and to confirm previously published results. Spectra of the resonance doublet line of neutral lithium Li I 670.78nm were taken with the High Dispersion Spectrograph at the Subaru 8.2m-telescope for a sample of five metal-poor stars (-3.12 < [Fe/H] < -2.19). The contribution of lithium-6 to the total observed line profile was estimated from the 1D-LTE analysis of the line asymmetry. Observed asymmetri...

    Angular distributions for the elastic scattering of 8Li on 9Be and the neutron transfer reactions 9Be(8Li,7Li)10Be and 9Be(8Li,9Li)8Be have been measured with a 27 MeV 8Li radioactive nuclear beam. Spectroscopic factors for 8Li|n=9Li and 7Li|n=8Li bound systems were obtained from the comparison between the experimental differential cross section and finite-range DWBA calculations with the code FRESCO. The spectroscopic factors obtained are compared to shell model calculations and to other experimental values from (d,p) reactions. Using the present values for the spectroscopic factor, cross sections for the direct neutron-capture reactions 7Li(n,g)8Li and 8Li(n,g)9Li were calculated in the framework of a potential model.

    A total of eight commercial spaceflight participants have launched to the International Space Station (ISS) on Soyuz vehicles. Based on an older mean age compared to career astronauts and an increased prevalence of medical conditions, spaceflight participants have provided the opportunity to learn about the effect of space travel on crewmembers with medical problems. The 12-d Soyuz TMA-13/12 ISS flight of spaceflight participant Richard Garriott included medical factors that required preflight intervention, risk mitigation strategies, and provided the opportunity for medical study on-orbit. Equally important, Mr. Garriott conducted extensive medical, scientific, and educational payload operations during the flight. These included 7 medical experiments and a total of 15 scientific projects such as protein crystal growth, Earth observations/photography, educational projects with schools, and amateur radio. The medical studies included the effect of microgravity on immune function, sleep, bone loss, corneal refractive surgery, low back pain, motion perception, and intraocular pressure. The overall mission success resulted from non-bureaucratic agility in mission planning, cooperation with investigators from NASA, ISS, International Partners, and the Korean Aerospace Research Institute, in-flight support and leadership from a team with spaceflight and Capcom experience, and overall mission support from the ISS program. This article focuses on science opportunities that suborbital and orbital spaceflight participant flights offer and suggests that the science program on Richard Garriott's flight be considered a model for future orbital and suborbital missions. The medical challenges are presented in a companion article.

The data set came from a hybrid of Eucalyptus urophylla x Eucalyptus tereticornis x E. pellita (controlled pollination, of the Forestry Experimental Module in the Gypsum Pole of Araripe, established in 2002. Eighty-three trees were used which heights were measured in all trees for six and half years. The fittings consisted on the estimation of the parameters of the Chapman-Richards model maximizing the log-likelihood of the error distributions using the symmetric distributions normal, t and Cauchy. For comparison of the adjusted models were used the criteria of Akaike Information Criterion (AIC and Bayesian (BIC and the mean absolute percentage error (MAPE. The model using the t distribution with 2 degrees of freedom (t2 had lower values of AIC and BIC and the model of Cauchy had lower value for MAPE. The results indicate that the model considering the t distribution for the errors presented best estimates of height growth of Eucalyptus clones in Gypsum Pole of Pernambuco.

    Through orthogonal experiment, a new type of LiClO4-LiNO3-LiBr eutectic salt with optimum mole ratio of n(LiClO4):n(LiNO3):n(LiBr)=1.6:3.8:1.0 was prepared. The poly(lithium acrylate-acrylonitrile)/LiClO4-LiNO3-LiBr solid polymer electrolytes were prepared with poly(lithium acrylate-acrylonitrile) and LiClO4-LiNO3-LiBr eutectic salts. The effect of LiClO4-LiNO3-LiBr eutectic salts content on the conductivity of solid polymer electrolytes was studied by alternating current impedance method, and the structures of eutectic salts and solid polymer electrolytes were characterized by differential thermal analysis, infrared spectroscopy and X-ray diffractometry. The results show that the room temperature conductivity of LiClO4-LiNO3-LiBr eutectic salts reaches 3.11×10-4 S·cm-1. The poly(lithium acrylate-acrylonitrile)/LiClO4-LiNO3-LiBr solid polymer electrolytes possess the highest room temperature conductivity at 70% LiClO4-LiNO3-LiBr eutectic salts content, and exhibit lower glass transition temperature of 75 ℃ compared with that of poly(lithium acrylate-acrylonitrile) of 105 ℃. A complex may be formed in the solid polymer electrolytes from the differential thermal analysis and infrared spectroscopy analysis. X-ray diffraction results show that the poly(lithium acrylate-acrylonitrile) can suppress the crystallization of eutectic salts in this system.

    2016-01-27

    A novel LiFePO4 material, in the shape of a nanomesh, has been rationally designed and synthesized based on the low crystal-mismatch strategy. The LiFePO4 nanomesh possesses several advantages in morphology and crystal structure, including a mesoporous structure, its crystal orientation that is along the [010] direction, and a shortened Li-ion diffusion path. These properties are favorable for their application as cathode in Li-ion batteries, as these will accelerate the Li-ion diffusion rate, improve the Li-ion exchange between the LiFePO4 nanomesh and the electrolyte, and reduce the Li-ion capacitive behavior during Li intercalation. So the LiFePO4 nanomesh exhibits a high specific capacity, enhanced rate capability, and strengthened cyclability. The method developed here can also be extended to other similar systems, for instance, LiMnPO4 , LiCoPO4 , and LiNiPO4 , and may find more applications in the designed synthesis of functional materials.

    Rate coefficients for inelastic collisions between Li and H atoms covering all transitions between the asymptotic states Li(2s,2p,3s,3p,3d,4s,4p,4d,4f)+H(1s) and Li^+ +H^- are presented for the temperature range 2000-8000 K based on recent cross-section calculations. The data are of sufficient completeness for non-LTE modelling of the Li I 670.8 nm and 610.4 nm features in late-type stellar atmospheres. Non-LTE radiative transfer calculations in both 1D and 3D model atmospheres have been carried out for test cases of particular interest. Our detailed calculations show that the classical modified Drawin-formula for collisional excitation and de-excitation (Li*+H Li*'+H) over-estimates the cross-sections by typically several orders of magnitude and consequently that these reactions are negligible for the line formation process. However, the charge transfer reactions collisional ion-pair production and mutual neutralization (Li*+H Li^+ +H^-) are of importance in thermalizing Li. In particular, 3D non-LTE calcu...

    The ground state of neutron-rich unbound $^{13}$Li was observed for the first time in a one-proton removal reaction from $^{14}$Be at a beam energy of 53.6 MeV/u. The $^{13}$Li ground state was reconstructed from $^{11}$Li and two neutrons giving a resonance energy of 120$^{+60}_{-80}$ keV. All events involving single and double neutron interactions in the Modular Neutron Array (MoNA) were analyzed, simulated, and fitted self-consistently. The three-body ($^{11}$Li+$n+n$) correlations within Jacobi coordinates showed strong dineutron characteristics. The decay energy spectrum of the intermediate $^{12}$Li system ($^{11}$Li+$n$) was described with an s-wave scattering length of greater than -4 fm, which is a smaller absolute value than reported in a previous measurement.

    The electrical conductivity of Cu-Li alloys was studied. And the distribution of electrons near Fermi surface was detected by synchrotron radiation instrument. The results show that the electrical conductivity of Cu-Li alloys decreases from 5. 22 × 10-9 S/m to 3. 69 × 10-9 S/m with the increase of Li content. Li can decrease the oxygen, sulfur and other impurities content in commercial Cu, but Li dissolved in Cu lattice leads to distortion of Cu lattice from 0. 005 %-0. 050 %, affects the valence band of Cu, increases the binding energy of surface electron, and decreases the electron density of Fermi surface simultaneously. So the electrical conductivity decreases gradually with the increase of Li content.

It analyzes whether the criticisms addressed to Rorty (Anti-enlightenment, Irrationality, Ontological Relativism, Epistemic Fallacy, Empiricism etc. can be maintained when confronted to another reading of his work, our own reading. The redescription indicates the limits and shortcomings of the description to which it makes opposition.

    Calculations of /sup 7/Li production occurring as a concomitant of thermonuclear runaways in hydrogen envelopes of white dwarfs are reported. It is found that sufficient /sup 7/Li can be produced in models displaying fast--nova-like features to suggest that the corresponding objects represent significant contributors to the /sup 7/Li enrichment of galactic matter. The sensitivities of these results to various assumptions and uncertainties are discussed.

    Graphical abstract: Highlights: > Anion substitution in LiBH{sub 4}. > Structure and properties of two LiBH{sub 4}-LiI solid solutions. > Stability upon heating and over time. > Hydrogen storage properties of LiBH{sub 4}-LiI. - Abstract: The new concept, anion substitution, is explored for possible improvement of hydrogen storage properties in the system LiBH{sub 4}-LiI. The structural chemistry and the substitution mechanism are analyzed using Rietveld refinement of in situ synchrotron radiation powder X-ray diffraction (SR-PXD) data, attenuated total reflectance infrared spectroscopy (ATR-IR), differential scanning calorimetry (DSC) and Sieverts measurements. Anion substitution is observed as formation of two solid solutions of Li(BH{sub 4}){sub 1-x}I{sub x}, which merge into one upon heating. The solid solutions have hexagonal structures (space group P6{sub 3}mc) similar to the structures of h-LiBH{sub 4} and {beta}-LiI. The solid solutions have iodide contents in the range {approx}0-62 mol% and are stable from below room temperature to the melting point at 330 deg. C. Thus the stability of the solid solutions is higher as compared to that of the orthorhombic and hexagonal polymorphs of LiBH{sub 4} and {alpha}- and {beta}-LiI. Furthermore, the rehydrogenation properties of the iodide substituted solid solution Li(BH{sub 4}){sub 1-x}I{sub x}, measured by the Sieverts method, are improved as compared to those of LiBH{sub 4}. After four cycles of hydrogen release and uptake the Li(BH{sub 4}){sub 1-x}I{sub x} solid solution maintains 68% of the calculated hydrogen storage capacity in contrast to LiBH{sub 4}, which maintains only 25% of the storage capacity after two cycles under identical conditions.

    PEOPLE in Yinan County refer to Li Xiuying, a doctor highly respected for her gynecological and obstetrics surgical skills, as "Magic Scalpel Li." Li Xiuying assumed the post as vice director of the Department of Gynecology and Obstetrics in the People’s Hospital in Yinan County at the young age of 27. She held the post for 12 years until 1988 when she was became director of the county’s Family Planning Service Center. Li had never pursued the new position, and was unable to accept the unexpected transfer, preferring instead to continue working in the Department of Gynecology and Obstetrics throughout her career.

    The electrochemical performances of nanoscale LiFePO4 and Li4Ti5O12 materials are described in this communication. The nanomaterials were synthesized by pyrolysis of an aerosol precursor. Both compositions required moderate heat-treatment to become electrochemically active. LiFePO4 nanoparticles were coated with a uniform, 2-4 nm thick carbon-coating using an organic precursor in the heat treatment step and showed high tap density of 1.24 g/cm3, in spite of 50-100 nm particle size and 2.9 wtpercent carbon content. Li4Ti5O12 nanoparticles were between 50-200 nm in size and showed tap density of 0.8 g/cm3. The nanomaterials were tested both in half cell configurations against Li-metal and also in LiFePO4/Li4Ti5O12 full cells. Nano-LiFePO4 showed high discharge rate capability with values of 150 and 138 mAh/g at C/25 and 5C, respectively, after constant C/25 charges. Nano-Li4Ti5O12 also showed high charge capability with values of 148 and 138 mAh/g at C/25 and 5C, respectively, after constant C/25 discharges; the discharge (lithiation) capability was comparatively slower. LiFePO4/Li4Ti5O12 full cells deliver charge/discharge capacity values of 150 and 122 mAh/g at C/5 and 5C, respectively.

  12. Modeling real-time PCR kinetics: Richards reparametrized equation for quantitative estimation of European hake (Merluccius merluccius).

    Real-time PCR is the most sensitive method for detection and precise quantification of specific DNA sequences, but it is not usually applied as a quantitative method in seafood. In general, benchmark techniques, mainly cycle threshold (Ct), are the routine method for quantitative estimations, but they are not the most precise approaches for a standard assay. In the present work, amplification data from European hake (Merluccius merluccius) DNA samples were accurately modeled by three sigmoid reparametrized equations, where the lag phase parameter (λc) from the Richards equation with four parameters was demonstrated to be the perfect substitute for Ct for PCR quantification. The concentrations of primers and probes were subsequently optimized by means of that selected kinetic parameter. Finally, the linear correlation among DNA concentration and λc was also confirmed.

  13. Exact solutions to traffic density estimation problems involving the Lighthill-Whitham-Richards traffic flow model using mixed integer programming

    Canepa, Edward S.

    2012-09-01

    This article presents a new mixed integer programming formulation of the traffic density estimation problem in highways modeled by the Lighthill Whitham Richards equation. We first present an equivalent formulation of the problem using an Hamilton-Jacobi equation. Then, using a semi-analytic formula, we show that the model constraints resulting from the Hamilton-Jacobi equation result in linear constraints, albeit with unknown integers. We then pose the problem of estimating the density at the initial time given incomplete and inaccurate traffic data as a Mixed Integer Program. We then present a numerical implementation of the method using experimental flow and probe data obtained during Mobile Century experiment. © 2012 IEEE.

  15. Of moths and men: Theo Lang and the persistence of Richard Goldschmidt's theory of homosexuality, 1916-1960.

    Science.gov (United States)

    Dietrich, M R

    2000-01-01

    Using an analogy between moths and men, in 1916, Richard Goldschmidt proposed that homosexuality was a case of genetic intersexuality. As he strove to create a unified theory of sex determination that would encompass animals ranging from moths to men, Goldschmidt's doubts grew concerning the association of homosexuality with intersexuality until, in 1931, he dropped homosexuality from his theory of intersexuality. Despite Goldschmidt's explicit rejection of his theory of homosexuality, Theo Lang, a researcher in the Genealogical-Demographic Department of the Institute for Psychiatric Research in Munich, revived it, maintained Goldschmidt's association with it, and argued on its behalf in publications from 1936 to 1960. Lang's appropriation of Goldschmidt's theory did not depend on his resolution of the difficulties Goldschmidt had found with his own theory. Lang and Goldschmidt, I argue, had fundamentally different scientific and social commitments that allowed one to reject this theory of homosexuality and the other to accept it.

  16. An exact explicit solution for one-dimensional, transient, nonlinear Richards' equation for modeling infiltration with special hydraulic functions

    Hayek, Mohamed

    2016-04-01

    This work develops a simple exact and explicit solution of the one-dimensional transient and nonlinear Richards' equation for soils in a special case of exponential water retention curve and power law hydraulic conductivity. The exact solution is obtained as traveling wave based on the approach proposed by Philip (1957, 1967) and adopted by Zlotnik et al. (2007). The obtained solution is novel, and it expresses explicitly the water content as function of the depth and time. It can be useful to model infiltration into semi-infinite soils with time-dependent boundary conditions and infiltration with constant boundary condition but space-dependent initial condition. A complete analytical inverse procedure based on the proposed analytical solution is presented which allows the estimation of hydraulic parameters. The proposed exact solution is also important for the verification of numerical schemes as well as for checking the implementation of time-dependent boundary conditions.

    Full Text Available Firstly, in this article it is examined the nature of the putative remarks concerning evolution of species that are found in the works that Richard Owen published before 1858; and then it is made the same thing with the few and vague evolutionist conjectures that Owen certainly made after the public presentation of Natural Selection Theory. Regarding the former topic, the goal will be to highlight the ambiguity of those Owen’s remarks, and concerning the latter topic what is looked for is to show that, when he explained his transmutationist thesis, Owen didn’t go beyond a pious theistic evolutionism, without postulating any mechanism of evolutionary change and remaining faithful to Design Theology praised by Paley.

    2012-01-01

    Full Text Available This article wants to follow the path and development of “black subject” in the USA through the novels of the Afro-American writer Richard Wright. Written between the 50’s and 70’s, Wright's novels tell us about the segregation and humiliation inflicted by white men, but also the process of self-colonisation that the Afro-American – no longer slaves, but still not entirely free, neither de iure, nor de facto – subjected themselves to. By telling the stories of young boys struggling with their growing up - from their childhood to the first steps into a violent adulthood - Wright shows – in a way which is never inane and rhetorical, nor blindly optimistic – the need to overcome the old models and racist stereotypes, and builds his own work as a true Bildungsroman of the “black subject”.

    1999-01-01

    Richard Reece, MD, interviewed Mansfield (Manny) Elkind on September 22, 1999 to talk about satisfying values and flexible thinking as keys to influencing physicians. Manny discusses why it's difficult for people to create lasting change in the workplace without recreating themselves. The effort to influence others often focuses on getting disciplined about changing behaviors, with the hope that feelings and attitudes will also change. This approach rarely works because behavior is changed only when values or beliefs change. People will get passionate and committed to achieving the organization's goals when they believe that their values will be satisfied as well. The leader's responsibility is to find ways of satisfying people's values, in addition to convincing them to use the organization's values as guides for behavior. A process is explored that helps people discover each other's values and preferences and transforms resistance to commitment.

    The temperature dependence of Li ions behavior of γ-LiAlO2 has been studied from 78 to 873 K. On heating, the Li ions underwent positional disordering along the structural channels, with the Li ions related modes at 220, 366 and 400 cm-1 broadening and weakening dramatically. An anomalous maximum in the bandwidths of the Li ions related modes is observed. It should be apparent that there are at least two distinct thermally activated processes. A model suggested by Andrade and Porto is used to describe the linewidth of a phonon.

    The influence of factors of the carbon black content, sintering temperature, sintering time, molar ratio of Li to Fe, as well as the electrochemical properties of LiFePO4 for lithium ion battery were studied. The only technology was obtained by using range analysis through Latin orthogonal experiment of L44 (16). The results show that the optimization synthesis technology of LiFePO4 is content of 5% doping carbon, sintering temperature of 700 ℃,molar ratio of Li to Fe of 1.03 : 1 and sintering time of 16 h. The optimized cathode synthesis techniques can make LiFePO4 have good electrochemical properties.

  3. Kinetic measurement and prediction of the hydrogen outgassing from the polycrystalline LiH/Li2O/LiOH system

    Due to the exothermic reaction of lithium hydride (LiH) salt with water during transportation and handling, there is always a thin film of lithium hydroxide (LiOH) present on the LiH surface. In dry or vacuum storage, this thin LiOH film slowly decomposes. We have used temperature-programmed reaction/decomposition (TPR) in combination with the isoconversion method of thermal analysis to determine the outgassing kinetics of H{sub 2}O from pure LiOH and H{sub 2} and H{sub 2}O from this thin LiOH film. H{sub 2} production via the reaction of LiH with LiOH, forming a lithium oxide (Li{sub 2}O) interlayer, is thermodynamically favored, with the rate of further reaction limited by diffusion through the Li{sub 2}O and the stability of the decomposing LiOH. Lithium hydroxide at the LiOH/vacuum interface also decomposes easily to Li{sub 2}O, releasing H{sub 2}O which subsequently reacts with LiH in a closed system to form H{sub 2}. At the onset of dry decomposition, where H{sub 2} is the predominant product, the activation energy for outgassing from a thin LiOH film is lower than that for bulk LiOH. However, as the reactions at the LiH/Li{sub 2}O/LiOH and at the LiOH/vacuum interfaces proceed, the overall activation energy barrier for the outgassing approaches that of bulk LiOH decomposition. The kinetics developed here predicts a hydrogen evolution profile in good agreement with hydrogen release observed during long term isothermal storage.

    Neutron and synchrotron studies have been performed on in situ hydriding of Li{sub 3}N. Commercial Li{sub 3}N is composed of {alpha} phase ({approx}70 wt.%) and {beta} phase ({approx}30 wt.%). We have performed experiments to convert {beta} {yields} {alpha}, and studied in situ deuteration using neutron diffraction experiments. We found concurrent phase evolution of Li{sub 2}ND, LiD, and LiND{sub 2}. Mass percentages of the phases evolved as a function of time and temperature have been quantified using General Structure Analysis System (GSAS) refinement of the neutron diffraction data. The problem of formation of the stable LiD is discussed in light of decreasing of the amount of LiD phase when the temperature is increased from 200 to 320 deg. C during dehydriding, and in addition the concentration of Li{sub 2}ND phase increased at this temperature. Lattice parameters, volume changes, phase evolutions in wt.% as a function of temperature and time are presented.

    Full Text Available Lithium bis (oxalate borate or LiBOB is an active material used as the electrolyte for lithium battery application. LiBOB (LiB(C2O42 powder was prepared from LiOH, H2C2O4 and H3BO3. The employed method was solid state reaction. LiBOB powder produced from the reaction was then observed using SEM and TEM. Surface area was analyzed using Quantachrome Nova 4200e. From the analysis analyzed using XRD to identify the resulting phases, crystal structure, and crystallite size. The functional groups were analyzed using FT-IR. The particle morphology was result, it was seen that the resulted phases were C4LiBO8 and LiB(C2O42.H2O, the crystal structure was orthorhombic with space group Pbca and Pnma. From the particle morphology observation it was shown that micro pores were created irregularly. When the observation was deepened, nanopores with elongated round shape were seen within the micropores. The pore size was approximately 50–100 nm. The surface area, total pore volume, and average pore diameter of LiBOB powder was 88.556 m2/g, 0.4252 cm3/g, and 19.2 nm respectively.

    One of the most promising means to increase the energy density of state-of-the-art lithium Li-ion batteries is to replace the graphite anode with a Li metal anode. While the direct use of Li metal may be highly advantageous, at present its practical application is limited by issues related to dendrite growth and low Coulombic efficiency, CE. Here operando electrochemical scanning transmission electron microscopy (STEM) is used to directly image the deposition/stripping of Li at the anode-electrolyte interface in a Li-based battery. A non-aqueous electrolyte containing small amounts of H2O as an additive results in remarkably different deposition/stripping properties as compared to the "dry" electrolyte when operated under identical electrochemical conditions. The electrolyte with the additive deposits more Li during the first cycle, with the grain sizes of the Li deposits being significantly larger and more variable. The stripping of the Li upon discharge is also more complete, i.e., there is a higher cycling CE. This suggests that larger grain sizes are indicative of better performance by leading to more uniform Li deposition and an overall decrease in the formation of Li dendrites and side reactions with electrolyte components, thus potentially paving the way for the direct use of Li metal in battery technologies.

    Uranium can be recovered from uranium oxide (UO2) spent fuel through the combination of the oxide reduction and electrorefining processes. During oxide reduction, the spent fuel is introduced to molten LiCl-Li2O salt at 650 degrees C and the UO2 is reduced to uranium metal via two routes: (1) electrochemically, and (2) chemically by lithium metal (Li0) that is produced electrochemically. However, the hygroscopic nature of both LiCl and Li2O leads to the formation of LiOH, contributing hydroxyl anions (OH-), the reduction of which interferes with the Li0 generation required for the chemical reduction of UO2. In order for the oxide reduction process to be an effective method for the treatment of uranium oxide fuel, the role of moisture in the LiCl-Li2O system must be understood. The behavior of moisture in the LiCl-Li2O molten salt system was studied using cyclic voltammetry, chronopotentiometry and chronoamperometry, while reduction to hydrogen was confirmed with gas chromatography.

    Full Text Available Anion substitution is at present one of the pathways to destabilize metal borohydrides for solid state hydrogen storage. In this work, a solid solution of LiBH4 and LiCl is studied by density functional theory (DFT calculations, thermodynamic modeling, X-ray diffraction, and infrared spectroscopy. It is shown that Cl substitution has minor effects on thermodynamic stability of either the orthorhombic or the hexagonal phase of LiBH4. The transformation into the orthorhombic phase in LiBH4 shortly after annealing with LiCl is for the first time followed by infrared measurements. Our findings are in a good agreement with an experimental study of the LiBH4-LiCl solid solution structure and dynamics. This demonstrates the validity of the adopted combined theoretical (DFT calculations and experimental (vibrational spectroscopy approach, to investigate the solid solution formation of complex hydrides.

    Full Text Available The first measurement of the one-neutron transfer reaction 11Li(p,d10Li performed using the IRIS facility at TRIUMF with a 5.7A MeV 11Li beam interacting with a solid H2 target is reported. The 10Li residue was populated strongly as a resonance peak with energy Er=0.62±0.04 MeV having a total width Γ=0.33±0.07 MeV. The angular distribution of this resonance is characterized by neutron occupying the 1p1/2 orbital. A DWBA analysis yields a spectroscopic factor of 0.67±0.12 for p1/2 removal strength from the ground state of 11Li to the region of the peak.

    Full Text Available On May 20, 1938, two American-made Chinese airplanes—Martin B-10 monoplane bombers—took off from Ningbo, Fujian province, in the direction of southwestern Japan. Instead of dropping bombs, they released propaganda materials produced by the Nationalist Party (Guomindang, pleading with the industrial workers, farmers, and petty bourgeois citizens of Japan to stop fighting China and resist their militarist government. This “humanitarian bombardment,” masterminded by Chiang Kai-shek, is little known today—perhaps deservedly so, for it had its embarrassing features. For one, the planes never reached the strategically important areas and merely flew over sparsely populated regions of Kumamoto and Miyazaki prefectures. Further, the propaganda materials were either voluntarily turned over to or confiscated by the Japanese authorities almost as soon as they hit the ground. As far as we can tell, the operation had little impact on the Japanese attitude toward China or on the Second Sino-Japanese War (1937–1945...
