The origins of species: the debate between August Weismann and Moritz Wagner.

PubMed

Weissman, Charlotte

2010-01-01

Weismann's ideas on species transmutation were first expressed in his famous debate with Moritz Wagner on the mechanism of speciation. Wagner suggested that the isolation of a colony from its original source is a preliminary and necessary factor for speciation. Weismann accepted a secondary, facilitating role for isolation, but argued that natural and sexual selection are the primary driving forces of species transmutation, and are always necessary and often sufficient causes for its occurrence. The debate with Wagner, which occurred between 1868 and 1872 within the framework of Darwin's discussions of geographical distribution, was Weismann's first public battle over the mechanism of evolution. This paper, which offers the first comprehensive analysis of this debate, extends previous analyses and throws light on the underlying beliefs and motivations of these early evolutionists, focusing mainly on Weismann's views and showing his commitment to what he later called "the all sufficiency of Natural Selection." It led to the crystallization of his ideas on the central and essential role of selection, both natural and sexual, in all processes of evolution, and, already at this early stage in his theoretical thinking, was coupled with sophisticated and nuanced approach to biological organization. The paper also discusses Ernst Mayr's analysis of the debate and highlights aspects of Weismann's views that were overlooked by Mayr and were peripheral to the discussions of other historians of biology.

Neumann, F.; Negrete-Aranda, R.; Contreras, J.; Müller, C.; Hutnak, M.; Gonzalez-Fernandez, A.; Harris, R. N.; Sclater, J. G.

2015-12-01

In May 2015, we conducted a cruise across the northern Gulf of California, an area of continental rift basin formation and rapid deposition of sediments. The cruise was undertaken aboard the R/V Alpha Helix; our goal was to study variation in superficial conductive heat flow, lateral changes in the shallow thermal conductivity structure, and advective transport of heat across the Wagner basin. We used a Fielax heat flow probe with 22 thermistors that can penetrate up to 6 m into the sediment cover. The resulting data set includes 53 new heat flow measurements collected along three profiles. The longest profile (42 km) contains 30 measurements spaced 1-2 km apart. The western part of the Wagner basin (hanging wall block) exhibit low to normal conductive heat flow whereas the eastern part of the basin (foot wall block) heat flow is high to very high (up to 2500 mWm-2). Two other short profiles (12 km long each) focused on resolving an extremely high heat flow anomaly up to 15 Wm-2 located near the intersection between the Wagner bounding fault system and the Cerro Prieto fault. We hypothesize that the contrasting heat flow values observed across the Wagner basin are due to horizontal water circulation through sand layers and fault pathways of high permeability. Circulation appears to be from west (recharge zone) to east (discharge zone). Additionally, our results reveal strong vertical advection of heat due to dehydration reactions and compaction of fine grained sediments.

Maxwell-Wagner relaxation in electrical imaging.

PubMed

Korjenevsky, A V

2005-04-01

The electric field tomography (EFT) method exploits interaction of high-frequency electric field with an inhomogeneous conductive medium without contact with the electrodes. The interaction is accompanied by a high-frequency redistribution of free charges inside the medium and leads to small and regular phase shifts of the field in the area surrounding an object. Such a kind of phenomenon is referred to as the Maxwell-Wagner relaxation. Measuring the perturbations of the field using the set of electrodes placed around the object enables us to reconstruct the internal structure of the medium, generally the spatial distribution of a nonlinear combination of permittivity and resistivity. In the case of biomedical applications the result of measurements is determined mainly by the resistivity of the tissues. Three-dimensional simulation based on the finite element method has demonstrated the feasibility of the technique.

Seismic reflection-based evidence of a transfer zone between the Wagner and Consag basins: implications for defining the structural geometry of the northern Gulf of California

NASA Astrophysics Data System (ADS)

González-Escobar, Mario; Suárez-Vidal, Francisco; Hernández-Pérez, José Antonio; Martín-Barajas, Arturo

2010-12-01

This study examines the structural characteristics of the northern Gulf of California by processing and interpreting ca. 415 km of two-dimensional multi-channel seismic reflection lines (data property of Petróleos Mexicanos PEMEX) collected in the vicinity of the border between the Wagner and Consag basins. The two basins appear to be a link between the Delfín Superior Basin to the south, and the Cerro Prieto Basin to the north in the Mexicali-Imperial Valley along the Pacific-North America plate boundary. The seismic data are consistent with existing knowledge of four main structures (master faults) in the region, i.e., the Percebo, Santa María, Consag Sur, and Wagner Sur faults. The Wagner and Consag basins are delimited to the east by the Wagner Sur Fault, and to the west by the Consag Sur Fault. The Percebo Fault borders the western margin of the modern Wagner Basin depocenter, and is oriented N10°W, dipping (on average) ˜40° to the northeast. The trace of the Santa María Fault located in the Wagner Basin strikes N19°W, dipping ˜40° to the west. The Consag Sur Fault is oriented N14°W, and dips ˜42° to the east over a distance of 21 km. To the east of the study area, the Wagner Sur Fault almost parallels the Consag Sur Fault over a distance of ˜86 km, and is oriented N10°W with an average dip of 59° to the east. Moreover, the data provide new evidence that the Wagner Fault is discontinuous between the two basins, and that its structure is more complex than previously reported. A structural high separates the northern Consag Basin from the southern Wagner Basin, comprising several secondary faults oriented NE oblique to the main faults of N-S direction. These could represent a zone of accommodation, or transfer zone, where extension could be transferred from the Wagner to the Consag Basin, or vice versa. This area shows no acoustic basement and/or intrusive body, which is consistent with existing gravimetric and magnetic data for the region.

[Problems and complications of leg lengthening with the Wagner apparatus].

PubMed

Herzog, R; Hefti, F

1992-06-01

Since 1971, we have performed 189 leg lengthening procedures using the Wagner method at our institution. The results obtained in the first 26 cases (1971-1973) showed a high complication rate, which led us to reconsider the indications for this procedure. In the present paper, we analyze the results of 37 leg lengthening procedures carried out in 32 patients during the last 10 years (1981-1990) in the children's unit of the orthopedic department of the University of Basle. We found a complication rate of 78%, and in 46% of cases there was more than one major complication. We did not distinguish between "complications" and "problems", because such distinctions are of little importance to the patient. The average age at the time of surgery was 14.8 years, and the average increase in length was 4.3 (2.2-9.2) cm. For each 1 cm of lengthening, an average of 21 days in hospital and 64 days of reduced weight-bearing were needed. Our conclusion is that the Wagner method makes it possible to attain the goal of leg lengthening, but the second step cannot reduce the length of stay in hospital or the length of time the patient needs the help of crutches. Bone remodeling is disturbed. Our preliminary experience with the Ilizarov method is more encouraging.

ThOMAs: the other means of assessment.

Williams, Andrew N; Debelle, Geoffrey D; Davies, Paul; Barrett, Tim G

2005-02-01

We describe a pilot study to investigate whether drawing "Thomas the Tank Engine" could be as effective a measure of developmental progress as the Goodenough-Harris Draw A Man test against the ThOMAs test (The Other Means of Assessment), with internal validation. The study included 95 children aged between 3 and 11 years of age, including a subgroup of 13 children with registered special needs from community and general pediatric clinics within Birmingham, UK, as a means of validation. There was no significant evidence that ThOMAS was either culturally or sex biased. Using regression analysis, nine items were found to correlate highly with actual age, and their total score gave a correlation of 0.563 with age. Adding further items did not increase this. After being converted into age-standardized scores, ThOMAS was as sensitive and specific as the Draw A Man test, and more so above a defined age-standardized threshold. This pilot study suggests that drawing Thomas the Tank Engine would appear to be as sensitive and specific a means of identifying children with special needs as the Goodenough-Harris Draw A Man test. The relatively small sample size means that further research is necessary to further define the age standardizations and to refine the ThOMAs test.

Experimental and Theoretical Studies on the Nazarov Cyclization/Wagner-Meerwein Rearrangement Sequence

PubMed Central

Lebœuf, David; Ciesielski, Jennifer

2012-01-01

Highly functionalized cyclopentenones can be generated stereospecifically by a chemoselective copper(II)-mediated Nazarov/Wagner-Meerwein rearrangement sequence of divinyl ketones. A detailed investigation of this sequence is described including a study of substrate scope and limitations. After the initial 4π electrocyclization, this reaction proceeds via two different sequential [1,2]-shifts, with selectivity that depends upon either migratory ability or the steric bulkiness of the substituents at C1 and C5. This methodology allows the creation of vicinal stereogenic centers, including adjacent quaternary centers. This sequence can also be achieved by using a catalytic amount of copper(II) in combination with NaBAr4f, a weak Lewis acid. During the study of the scope of the reaction, a partial or complete E / Z isomerization of the enone moiety was observed in some cases prior to the cyclization, which resulted in a mixture of diastereomeric products. Use of a Cu(II)-bisoxazoline complex prevented the isomerization, allowing high diastereoselectivity to be obtained in all substrate types. In addition, the reaction sequence was studied by DFT computations at the UB3LYP/6-31G(d,p) level, which are consistent with the proposed sequences observed, including E / Z isomerizations and chemoselective Wagner-Meerwein shifts.

2004-01-01

The objective of this study was to evaluate the performance of Wagner-Nelson, Loo-Reigelman, and statistical moments methods in determining the absorption rate constant(s) in the presence of a secondary peak. These methods were also evaluated when there were two absorption rates without a secondary peak. Different sets of plasma concentration versus time data for a hypothetical drug following one or two compartment models were generated by simulation. The true ka was compared with the ka estimated by Wagner-Nelson, Loo-Riegelman and statistical moments methods. The results of this study indicate that Wagner-Nelson, Loo-Riegelman and statistical moments methods may not be used for the estimation of absorption rate constants in the presence of a secondary peak or when absorption takes place with two absorption rates.

Vivien Thomas (1910-1985) was an African-American scientist, pioneer, and renowned educator. Thomas's contributions to cardiovascular surgery were unequivocal, and yet it was only after his death that he gained more widespread recognition. Thomas's more notable work involves aiding in the discovery of the cause of traumatic shock, designing and guiding the first operation to treat Tetralogy of Fallot, carrying out the first atrial septectomy, and helping develop the electrical defibrillator. Thomas struggled amidst the adversities of racism and the Great Depression (1929-1941), armed merely with a high school degree. Nevertheless, his genius and determination eventually led him to receive an honorary doctorate from John Hopkins University. His story inspired the creation of the award winning PBS documentary in 2003 Partners of the Heart and also the 2004 Emmy Award-winning HBO film Something the Lord Made. This article will aim to provide an overview to the more notable events in Thomas's amazing tale, with a particular focus on his work on the Tetralogy of Fallot.

Transfemoral implantation of the Wagner SL stem. The abolition of subsidence and enhancement of osteotomy union rate using Dall-Miles cables.

PubMed

Warren, P J; Thompson, P; Fletcher, M D A

2002-12-01

The Wagner SL uncemented revision stem has been utilised successfully for revision hip surgery where marked loss of proximal bone stock co-exists or where there is a periprosthetic fracture. Implanted via the transfemoral approach, one significant difficulty appears to be a tendency for implant subsidence, which in some cases has been troublesome enough to necessitate early revision (usually to a larger prosthesis). A change in our operative practice allowed us to review the effects of using either wire cerclages or 2.0 mm Dall-Miles cables for prophylactic wiring of the distal femur. Seventeen Wagner SL stems, inserted via the transfemoral approach, were studied in 16 patients. We found those patients prophylactically wired with Dall-Miles cables demonstrated no subsidence in comparison with those in whom heavy wire cerclage had been utilised (mean subsidence 6 mm; p=0.001). In addition, we found that closure of the proximal osteotomy with wires conferred a more reliable rate of union in comparison with those closed with heavy sutures. We recommend the use of Dall-Miles cables for distal cerclage and osteotomy closure for the Wagner prosthesis.

Julius Wagner-Jauregg and the Legacy of Malarial Therapy for the Treatment of General Paresis of the Insane

Tsay, Cynthia J.

2013-01-01

Julius Wagner-Jauregg, a preeminent Austrian psychiatrist was awarded the Nobel Prize in Medicine in 1927 for the development of malaria therapy for the treatment of neurosyphilis, or general paresis of the insane. Despite being only one of three psychiatrists to win a Nobel Prize, he has faded from public consciousness and his name recognition pales in comparison to his contemporary and fellow Austrian, Sigmund Freud. This paper explores his contributions to the field of biological psychiatry and also touches upon reasons, such as the growing bioethics movement, his controversial affiliation with the Nazi Party, and the evolution of neurosyphilis, that explain why Wagner-Jauregg is not more widely celebrated for his contributions to the field of psychiatry, even though his malarial treatment could be considered the earliest triumph of biological psychiatry over psychoanalysis.

A gift from Oxford: the Osler-Thomas connection

PubMed Central

2012-01-01

In June 1926, Dr. Henry M. Thomas Jr. (“Hal”) received as a gift from Grace Osler in Oxford an Einhorn Duodenal Bucket Set that had belonged to Sir William Osler. The Thomases were a distinguished multigenerational physician family of Baltimore with high educational standards and major accomplishments in medicine and medical education. An extraordinary number of the Thomas women earned doctorates and made significant contributions in an era when this was a pioneering achievement. This is exemplified by Martha Carey Thomas, who earned a PhD in 1882 and served as dean and president of Bryn Mawr College for women. As a leading feminist and member of the Women's Fund Committee, she was a major force in providing the endowment that permitted the opening of the Johns Hopkins School of Medicine under the strict stipulations that admission requirements include an undergraduate degree and that women be admitted on the basis of total equality with men. Osler established relationships that extended over three generations of the Thomas family during his Baltimore tenure, an influence that proved mutually beneficial. PMID:23077379

Tectonoestratigraphic and Thermal Models of the Tiburon and Wagner Basins, northern Gulf of California Rift System

NASA Astrophysics Data System (ADS)

Contreras, J.; Ramirez Zerpa, N. A.; Negrete-Aranda, R.

2014-12-01

The northern Gulf of California Rift System consist sofa series faults that accommodate both normal and strike-slip motion. The faults formed a series of half-greens filled with more than 7 km of siliciclastic suc­cessions. Here, we present tectonostratigraphic and heat flow models for the Tiburón basin, in the southern part of the system, and the Wag­ner basin in the north. The models are constrained by two-dimensional seis­mic lines and by two deep boreholes drilled by PEMEX­-PEP. Analysis of the seismic lines and models' results show that: (i) subsidence of the basins is controlled by high-angle normal faults and by flow of the lower crust, (ii) basins share a common history, and (iii) there are significant differences in the way brittle strain was partitioned in the basins, a feature frequently observed in rift basins. On one hand, the bounding faults of the Tiburón basin have a nested geometry and became active following a west-to-east sequence of activation. The Tiburon half-graben was formed by two pulses of fault activity. One took place during the protogulf extensional phase in the Miocene and the other during the opening of Gulf of California in the Pleistocene. On the other hand, the Wagner basin is the result of two fault generations. During the late-to middle Miocene, the west-dipping Cerro Prieto and San Felipe faults formed a domino array. Then, during the Pleistocene the Consag and Wagner faults dissected the hanging-wall of the Cerro Prieto fault forming the modern Wagner basin. Thermal modeling of the deep borehole temperatures suggests that the heat flow in these basins in the order of 110 mW/m2 which is in agreement with superficial heat flow measurements in the northern Gulf of California Rift System.

Llewellyn Hilleth Thomas was born in 1903 and died in 1992 at the age of 88. His name is known by most for only two things, Thomas precession and the Thomas-Fermi atom. The many other facets of his career - astrophysics, atomic and molecular physics, nonlinear problems, accelerator physics, magnetohydrodynamics, computer design principles and software and hardware - are largely unknown or forgotten. I review his whole career - his early schooling, his time at Cambridge, then Copenhagen in 1925-26, and back to Cambridge, his move to the US as an assistant professor at Ohio State University in 1929, his wartime years at the Ballistic Research Laboratory, Aberdeen Proving Grounds, then in 1946 his new career as a unique resource at IBM's Watson Scientific Computing Laboratory and Columbia University until his first retirement in 1968, and his twilight years at North Carolina State University. Although the Thomas precession and the Thomas-Fermi atom may be the jewels in his crown, his many other accomplishments add to our appreciation of this consummate applied mathematician and physicist. )

Conceptual Model for the Geothermal System of the Wagner Basin, Gulf of California

Cerro Prieto in northwestern Mexico is one of the biggest geothermal plants in the world. Cerro Prieto sits in the Gulf of California rift system, which consists of a series of spreading centers and transform faults. The aim of this study is to evaluate the geothermal potential of the nearby offshore Wagner basin. To this end, we acquired and analyzed a set of different methods, such as reflection seismics, heat flow, magnetotelluric and controlled source electromagnetics, hydrogeochemistry and echosounder. Seismic reflection data show that the Wagner basin is a semi-graben, A profile crossing it shows numerous closely spaced faults, particularly in its eastern part. We found very high heat flow values, in excess of 1000 mW/m2, and large variability on the eastern flank of the Wagner basin, whereas there are more consistent and much lower values across the central and western parts. The high and variable heat flow values are suggestive of advective heat transfer We collected cores and interstitial water samples. The hydrogeochemistry analyses show that in the cores recovered from high heat flow areas, the relations bromide/choride and bromide/sulfide are clearly different from sea water. In contrast, those relations were close to sea water in areas with low heat flow. Similarly, the isotope relations such as 2H/18O show a similar pattern, further indicating the groundwater origin of the interstitial water found in high heat flow zones. In the magnetoteluric measurements we found the presence of a deep conductor that is located approximately under the basin center, extends from the base of the crust to depths of about 40 km, and dips toward the NE. This conductor is probably related to the heat source of the geothermal system. Active source electromagnetics show the presence of shallow conductors that correlate with the faults visible in the seismic sections. There are two distinct conductors, one in the eastern flank and another in the western flank of the basin

Iron status determination in pregnancy using the Thomas plot.

PubMed

Weyers, R; Coetzee, M J; Nel, M

Physiological changes during pregnancy affect routine tests for iron deficiency. The reticulocyte haemoglobin equivalent (RET-He) and serum-soluble transferrin receptor (sTfR) assay are newer diagnostic parameters for the detection of iron deficiency, combined in the Thomas diagnostic plot. We used this plot to determine the iron status of pregnant women presenting for their first visit to an antenatal clinic in Bloemfontein, South Africa. Routine laboratory tests (serum ferritin, full blood count and C-reactive protein) and RET-He and sTfR were performed. The iron status was determined using the Thomas plot. For this study, 103 pregnant women were recruited. According to the Thomas plot, 72.8% of the participants had normal iron stores and erythropoiesis. Iron-deficient erythropoiesis was detected in 12.6%. A third of participants were anaemic. Serum ferritin showed excellent sensitivity but poor specificity for detecting depleted iron stores. HIV status had no influence on the iron status of the participants. Our findings reiterate that causes other than iron deficiency should be considered in anaemic individuals. When compared with the Thomas plot, a low serum ferritin is a sensitive but nonspecific indicator of iron deficiency. The Thomas plot may provide useful information to identify pregnant individuals in whom haematologic parameters indicate limited iron availability for erythropoiesis. © 2015 John Wiley & Sons Ltd.

Szabo, Richard J.; Tierz, Miguel; Departamento de Analisis Matematico, Facultad de Ciencias Matematicas, Universidad Complutense de Madrid, Plaza de Ciencias 3, 28040 Madrid

We show that the partition functions which enumerate Donaldson-Thomas invariants of local toric Calabi-Yau threefolds without compact divisors can be expressed in terms of specializations of the Schur measure. We also discuss the relevance of the Hall-Littlewood and Jack measures in the context of BPS state counting and study the partition functions at arbitrary points of the Kaehler moduli space. This rewriting in terms of symmetric functions leads to a unitary one-matrix model representation for Donaldson-Thomas theory. We describe explicitly how this result is related to the unitary matrix model description of Chern-Simons gauge theory. This representation is used tomore » show that the generating functions for Donaldson-Thomas invariants are related to tau-functions of the integrable Toda and Toeplitz lattice hierarchies. The matrix model also leads to an interpretation of Donaldson-Thomas theory in terms of non-intersecting paths in the lock-step model of vicious walkers. We further show that these generating functions can be interpreted as normalization constants of a corner growth/last-passage stochastic model.« less

Generalized Thomas-Fermi equations as the Lampariello class of Emden-Fowler equations

NASA Astrophysics Data System (ADS)

Rosu, Haret C.; Mancas, Stefan C.

2017-04-01

A one-parameter family of Emden-Fowler equations defined by Lampariello's parameter p which, upon using Thomas-Fermi boundary conditions, turns into a set of generalized Thomas-Fermi equations comprising the standard Thomas-Fermi equation for p = 1 is studied in this paper. The entire family is shown to be non integrable by reduction to the corresponding Abel equations whose invariants do not satisfy a known integrability condition. We also discuss the equivalent dynamical system of equations for the standard Thomas-Fermi equation and perform its phase-plane analysis. The results of the latter analysis are similar for the whole class.

Nonextensive Thomas-Fermi model

NASA Astrophysics Data System (ADS)

Shivamoggi, Bhimsen; Martinenko, Evgeny

2007-11-01

Nonextensive Thomas-Fermi model was father investigated in the following directions: Heavy atom in strong magnetic field. following Shivamoggi work on the extension of Kadomtsev equation we applied nonextensive formalism to father generalize TF model for the very strong magnetic fields (of order 10e12 G). The generalized TF equation and the binding energy of atom were calculated which contain a new nonextensive term dominating the classical one. The binding energy of a heavy atom was also evaluated. Thomas-Fermi equations in N dimensions which is technically the same as in Shivamoggi (1998) ,but behavior is different and in interesting 2 D case nonextesivity prevents from becoming linear ODE as in classical case. Effect of nonextensivity on dielectrical screening reveals itself in the reduction of the envelope radius. It was shown that nonextesivity in each case is responsible for new term dominating classical thermal correction term by order of magnitude, which is vanishing in a limit q->1. Therefore it appears that nonextensive term is ubiquitous for a wide range of systems and father work is needed to understand the origin of it.

William Osler and Seymour Thomas, “the boy artist of Texas”

PubMed Central

2016-01-01

Critics consider the 1908–1909 portrait of William Osler by S. Seymour Thomas the best of six oil-on-canvas portraits of Osler done from life, including those by the more acclaimed US artists John Singer Sargent and William Merritt Chase. Osler called it “the best pictorial diagnosis I have ever seen” and told Thomas “I am at your service.” A reappraisal of Seymour Thomas explains why his portrait makes us feel much as the artist did in Osler's presence, which is the original English-language definition of “empathy.” Thomas told his subject that “I feel that you can look clear through me and see the wall on the other side.” The intensity of Osler's gaze affects us similarly. The portrait satisfied Osler, but his wife, Grace Revere Osler, never warmed to it, perhaps because it depicts so clearly a highly focused, agenda-driven man. Helen Thomas used the portrait to promote her husband's business, and, after a tortuous history, the portrait eventually returned to Oxford University, where it now hangs inconspicuously in the Radcliffe Science Library.

The generalization of the Mermin-Wagner theorem and the possibility of long-range order in the isotropic discrete one-dimensional quantum Heisenberg model

NASA Astrophysics Data System (ADS)

Rudoy, Yu. G.; Kotelnikova, O. A.

2012-10-01

The problem of existence of long-range order in the isotropic quantum Heisenberg model on the D=1 lattice is reconsidered in view of the possibility of sufficiently slow decaying exchange interaction with infinite effective radius. It is shown that the macrosopic arguments given by Landau and Lifshitz and then supported microscopically by Mermin and Wagner fail for this case so that the non-zero spontaneous magnetization may yet exist. This result was anticipated by Thouless on the grounds of phenomenological analysis, and we give its microscopic foundation, which amounts to the generalization of Mermin-Wagner theorem for the case of the infinite second moment of the exchange interaction. Two well known in lattice statistics models - i.e., Kac-I and Kac-II - illustrate our results.

Importance of Thomas single-electron transfer in fast p-He collisions

Fischer, D.; Max-Planck-Institut fuer Kernphysik, Saupfercheckweg 1 D-69126; Gudmundsson, M.

We report experimental angular differential cross sections for nonradiative single-electron capture in p-He collisions (p+ He -> H + He{sup +}) with a separate peak at the 0.47 mrad Thomas scattering angle for energies in the 1.3-12.5 MeV range. We find that the intensity of this peak scales with the projectile velocity as v{sub P}{sup -11}. This constitutes the first experimental test of the prediction from 1927 by L. H. Thomas [Proc. R. Soc. 114, 561 (1927)]. At our highest energy, the peak at the Thomas angle contributes with 13.5% to the total integrated nonradiative single-electron capture cross section.

Statistical ultrasonics: the influence of Robert F. Wagner

NASA Astrophysics Data System (ADS)

Insana, Michael F.

2009-02-01

An important ongoing question for higher education is how to successfully mentor the next generation of scientists and engineers. It has been my privilege to have been mentored by one of the best, Dr Robert F. Wagner and his colleagues at the CDRH/FDA during the mid 1980s. Bob introduced many of us in medical ultrasonics to statistical imaging techniques. These ideas continue to broadly influence studies on adaptive aperture management (beamforming, speckle suppression, compounding), tissue characterization (texture features, Rayleigh/Rician statistics, scatterer size and number density estimators), and fundamental questions about how limitations of the human eye-brain system for extracting information from textured images can motivate image processing. He adapted the classical techniques of signal detection theory to coherent imaging systems that, for the first time in ultrasonics, related common engineering metrics for image quality to task-based clinical performance. This talk summarizes my wonderfully-exciting three years with Bob as I watched him explore topics in statistical image analysis that formed a rational basis for many of the signal processing techniques used in commercial systems today. It is a story of an exciting time in medical ultrasonics, and of how a sparkling personality guided and motivated the development of junior scientists who flocked around him in admiration and amazement.

Thomas Harriot: the first telescopic astronomer

NASA Astrophysics Data System (ADS)

Chapman, A.

2008-12-01

I am going to devote the 2007 Christmas Lecture to Thomas Harriot. I think it is appropriate to do so because next year, 2008, will be the 400th anniversary of the invention of the telescope, by Hans Lippershey, Zacharias Jannsen, and perhaps other Dutchmen. And although the principles of the instrument were first made public in 1608, it was at least eight months before anybody recognised that it possessed any scientific potential. For at first, the telescope was used as a military or naval device, or regarded purely as a novelty. As far as we can tell from the historical record, however, it was Thomas Harriot who became the first person to look at an astronomical body through a telescope, on or before 1609 July 26, when he came to realise that the image of the Moon produced by it was very different from what was seen by the naked eye, although he did not publish his discovery.

The article sets the cholera motif in Thomas Mann's famous novella Death in Venice against the historical context from which it partially originates. It is shown that this motif, while undoubtedly appropriated to serve Mann's own poetic ends, has a solid grounding in historical and autobiographical fact, thus blurring the boundaries between fact and fiction. The article illustrates the verifiable events of the outbreak of the Venetian cholera epidemic in May 1911, which Mann partly witnessed himself, during a holiday trip to Brioni and Venice, and partly heard and read about. It is established that Thomas Mann's account of the cholera in Venice in his novella is characterised by a rare and almost preternatural insightfulness into an otherwise murky affair that was marked by rumours, speculations and denials.

The pre-Anschluss Vienna School of Medicine - the physicians: Sigmund Freud (1856-1939), Julius Wagner-Jauregg (1857-1940) and Karel Wenckebach (1864-1940).

Three physicians are discussed. Sigmund Freud, probably the best-known member of the Vienna School of Medicine, was the path-breaking pioneer in psychoanalysis and psychotherapy. Julius Wagner-Jauregg was a psychiatrist who discovered the link between iodine deficiency and goitre and also developed malaria therapy to treat progressive paralysis caused by syphilis for which he was awarded the Nobel Prize. Karel Wenckebach, the pioneering Dutch cardiologist, is best known for the Wenckebach block. After the Anschluss, fate dealt very different hands to these three physicians. Freud fled to London where he soon died. Wagner-Jauregg, who had some pan-Germanic sympathies as well as views on eugenics, left a controversial legacy. The Dutch cardiologist Wenckebach died in Vienna shortly after his homeland had been invaded in 1940 by that of his hosts. © IMechE 2014.

2009-12-01

Firstly in this paper, the influence of H 2 and water vapor content on selective oxidation occurred in continuous hot-dip galvanizing has been studied by thermodynamics and Wagner model, then, the Gibbs energy of each possible aluminothermic reducing reaction in zinc bath was calculated in order to judge the possibility of these reactions. It was found that oxides' amounts and oxidation type were greatly related to the H 2 and water content in the annealing atmosphere. And from the view of thermodynamics, surface oxides (MnO, Cr 2O 3, SiO 2 etc.) can be reduced by the effective Al in Zn bath.

A Rescorla-Wagner drift-diffusion model of conditioning and timing

PubMed Central

Alonso, Eduardo

2017-01-01

Computational models of classical conditioning have made significant contributions to the theoretic understanding of associative learning, yet they still struggle when the temporal aspects of conditioning are taken into account. Interval timing models have contributed a rich variety of time representations and provided accurate predictions for the timing of responses, but they usually have little to say about associative learning. In this article we present a unified model of conditioning and timing that is based on the influential Rescorla-Wagner conditioning model and the more recently developed Timing Drift-Diffusion model. We test the model by simulating 10 experimental phenomena and show that it can provide an adequate account for 8, and a partial account for the other 2. We argue that the model can account for more phenomena in the chosen set than these other similar in scope models: CSC-TD, MS-TD, Learning to Time and Modular Theory. A comparison and analysis of the mechanisms in these models is provided, with a focus on the types of time representation and associative learning rule used. PMID:29095819

2011-01-01

Purpose To detail the highly variable ocular phenotypes of a French family affected with an autosomal dominantly inherited vitreoretinopathy and to identify the disease gene. Methods Sixteen family members with ten affected individuals underwent detailed ophthalmic evaluation. Genetic linkage analysis and gene screening were undertaken for genes known to be involved in degenerative and exudative vitreoretinopathies. Qualitative reverse transcriptase-PCR analysis of the versiscan (VCAN) transcripts was performed after mutation detection in the VCAN gene. Results The first index patient of this French family was referred to us because of a chronic uveitis since infancy; this uveitis was associated with exudative retinal detachment in the context of a severe uncharacterized familial vitreoretinopathy. Genetic linkage was obtained to the VCAN locus, and we further identified a new pathogenic mutation at the highly conserved splice acceptor site in intron 7 of the VCAN gene (c.4004–2A>T), which produced aberrantly spliced VCAN transcripts. Conclusions Extensive molecular investigation allowed us to classify this familial vitreoretinopathy as Wagner syndrome. This study illustrates the need to confirm clinical diagnosis by molecular genetic testing and adds new ocular phenotypes to the Wagner syndrome, such as vascular and inflammatory features.

Instantons, quivers and noncommutative Donaldson-Thomas theory

NASA Astrophysics Data System (ADS)

Cirafici, Michele; Sinkovics, Annamaria; Szabo, Richard J.

2011-12-01

We construct noncommutative Donaldson-Thomas invariants associated with abelian orbifold singularities by analyzing the instanton contributions to a six-dimensional topological gauge theory. The noncommutative deformation of this gauge theory localizes on noncommutative instantons which can be classified in terms of three-dimensional Young diagrams with a colouring of boxes according to the orbifold group. We construct a moduli space for these gauge field configurations which allows us to compute its virtual numbers via the counting of representations of a quiver with relations. The quiver encodes the instanton dynamics of the noncommutative gauge theory, and is associated to the geometry of the singularity via the generalized McKay correspondence. The index of BPS states which compute the noncommutative Donaldson-Thomas invariants is realized via topological quantum mechanics based on the quiver data. We illustrate these constructions with several explicit examples, involving also higher rank Coulomb branch invariants and geometries with compact divisors, and connect our approach with other ones in the literature.

During the 16 years Thomas Gainsborough (1727-88) lived in Bath he was especially friendly with two eminent physicians, Rice Charleton (1723-88) and Abel Moysey (1715-80). They both treated Gainsborough for a severe nervous illness. In return he painted portraits of them without charge. Gainsborough's two daughters were both mentally unstable and when the elder one became very ill he had to call for the services of a third Bath physician, Dr Ralph Schomberg (1714-92), who was also the subject of a fine portrait. In the final phase of his life Gainsborough moved to London, where he suffered his fatal illness, possibly squamous cell carcinoma. For this he was treated by William Heberden (1710-1801) and John Hunter (1728-93).

Relativistic equation of state at subnuclear densities in the Thomas-Fermi approximation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Zhang, Z. W.; Shen, H., E-mail: shennankai@gmail.com

We study the non-uniform nuclear matter using the self-consistent Thomas-Fermi approximation with a relativistic mean-field model. The non-uniform matter is assumed to be composed of a lattice of heavy nuclei surrounded by dripped nucleons. At each temperature T, proton fraction Y{sub p} , and baryon mass density ρ {sub B}, we determine the thermodynamically favored state by minimizing the free energy with respect to the radius of the Wigner-Seitz cell, while the nucleon distribution in the cell can be determined self-consistently in the Thomas-Fermi approximation. A detailed comparison is made between the present results and previous calculations in the Thomas-Fermimore » approximation with a parameterized nucleon distribution that has been adopted in the widely used Shen equation of state.« less

Thomas-Fermi approximation for a condensate with higher-order interactions

DOE Office of Scientific and Technical Information (OSTI.GOV)

Thoegersen, M.; Jensen, A. S.; Zinner, N. T.

We consider the ground state of a harmonically trapped Bose-Einstein condensate within the Gross-Pitaevskii theory including the effective-range corrections for a two-body zero-range potential. The resulting nonlinear Schroedinger equation is solved analytically in the Thomas-Fermi approximation neglecting the kinetic-energy term. We present results for the chemical potential and the condensate profiles, discuss boundary conditions, and compare to the usual Thomas-Fermi approach. We discuss several ways to increase the influence of effective-range corrections in experiment with magnetically tunable interactions. The level of tuning required could be inside experimental reach in the near future.

Myers, Kyle J.

2009-02-01

Over the course of his long and productive career, Dr. Robert F. Wagner built a framework for the evaluation of imaging systems based on a task-based, decision theoretic approach. His most recent contributions involved the consideration of the random effects associated with multiple readers of medical images and the logical extension of this work to the problem of the evaluation of multiple competing classifiers in statistical pattern recognition. This contemporary work expanded on familiar themes from Bob's many SPIE presentations in earlier years. It was driven by the need for practical solutions to current problems facing FDA'S Center for Devices and Radiological Health and the medical imaging community regarding the assessment of new computer-aided diagnosis tools and Bob's unique ability to unify concepts across a range of disciplines as he gave order to increasingly complex problems in our field.

2017-11-01

Peter of Tilleberi (Tilbury), later known as bishop Thomas of Wroclaw, after completing his studies (in Bologna or in Montpellier) worked as a physician in northern Italy and probably in Spain. Later through Germany and Bohemia, he came to Wroclaw in 1336 where he joined the Order of St. Dominic. In 1352, Thomas was made an auxiliary bishop of the diocese of Wroclaw. After the episcopal consecration, Thomas stopped living in the abbey, but all the time he was well known both as a priest and physician. He is known as an author of several treatises on medical sciences. His most important work entitled Michi competit (i.e. It suits me) is composed of four parts: Regimen sanitatis (i.e. Hygiene), Aggregatum (i.e. Aggregation), Antidotarium (i.e. Medicine directory) and Practica medicinalis (i.e. Medical practices). Moreover, he is the author of other treatises including, for example, De phlebotomia et de iudiciis cruoris (i.e. On phlebotomy and blood content) and De urinis (i.e. On urine). Some Polish scientists claim that bishop Thomas of Wroclaw with his knowledge and industriousness functioned as a university faculty of medicine even though the University of Cracow had not been established yet.

Understanding the fate of the oxyallyl cation following Nazarov electrocyclization: sequential Wagner-Meerwein migrations and the synthesis of spirocyclic cyclopentenones

PubMed Central

Huang, Jie; Lebœuf, David; Frontier, Alison J.

2011-01-01

A general reaction sequence is described that involves Nazarov cyclization followed by two sequential Wagner Meerwein migrations, to afford spirocyclic compounds from divinyl ketones in the presence of one equivalent of copper(II) complexes. A detailed investigation of this sequence is described including a study of substrate scope and limitations. It was found that after 4π electrocyclization, two different pathways are available to the oxyallyl cation intermediate: elimination of a proton can give the usual Nazarov cycloadduct, or ring contraction can give an alternative tertiary carbocation. After ring contraction, either [1,2]-hydride or carbon migration can occur, depending upon the substitution pattern of the substrate, to furnish spirocyclic products. The rearrangement pathway is favored over the elimination pathway when catalyst loading was high and the copper(II) counterion is noncoordinating. Several ligands were found to be effective for the reaction. Thus, the reaction sequence can be controlled by judicious choice of reaction conditions to allow selective generation of richly functionalized spirocycles. The three steps of the sequence are stereospecific: electrocyclization followed by two [1,2]-suprafacial Wagner-Meerwein shifts: the ring contraction and then an hydride, alkenyl or aryl shift. The method allows stereospecific installation of adjacent stereocenters or adjacent quaternary centers arrayed around a cyclopentenone ring. PMID:21466152

2004-10-01

Oxygen-deficient hexagonal BaTiO3 single crystals, with dielectric constant ε '˜105 and loss component tan δ ˜0.13 at room temperature and a linear temperature dependence of ε' in the range 70-100K, was analyzed by impedance spectroscopy analysis. Two capacitors, bulk and interfacial boundary layer, were observed, and the colossal dielectric constant was mainly dominated by the interfacial boundary layers due to Maxwell-Wagner effect. After annealing the oxygen-deficient hexagonal BaTiO3 at 663K, the ε ' and tanδ became, respectively, 2×104 and 0.07 at room temperature. This work showed an important technological implication as annealing at lower temperatures would help to obtain materials with tailored dielectric properties.

The Bo (meaning 'ox' in the Venetian dialect) is the historic seat of the University of Padua, founded in 1222. A full-length portrait of Thomas Linacre stands in its prestigious Sala dei Quaranta (Hall of the Forty), so called because of the portraits of forty great foreign scholars of the University, painted by Giacomo dal Forno in 1942. Thomas Linacre came to Italy in 1485, following an embassy by Henry VII to the Vatican. Linacre visited Bologna, Florence, Rome, Venice, Vicenza and Padua, where he took his degree in medicine in 1496 with great distinction. During his stay in Italy he met illustrious humanists and physicians, including Poliziano, Hermolaus Barbarus and Aldus Manutius Romanus, and Nicolaus Leonicenus who further stimulated him to the translation of classic works by Hippocrates and Galen. In 1518 Linacre played a pivotal role in the foundation of the Royal College of Physicians in London which, as first President, he organized on the basis of Italian models. With his portrait, the University of Padua celebrates the life and work of an astonishing figure linking the Italian and English medical cultures.

The wish for annihilation in 'love-death' as collapse of the need for recognition, in Wagner's Tristan und Isolde.

PubMed

Bergstein, Moshe

2013-08-01

Wagner's Tristan und Isolde holds a central position in Western music and culture. It is shown to demonstrate consequences of interruption of developmental processes involving the need for recognition of subjectivity, resulting in the collapse of this need into the wish for annihilation of self and other through 'love-death' [Liebestod]. A close reading of the musical language of the opera reveals how this interruption is demonstrated, and the consequent location of identity outside of language, particularly suitable for expression in music. Isolde's dynamics are presented as distinct from that of Tristan, and in contrast to other interpretations of Tristan and Isolde's love as an attack on the Oedipal order, or as a regressive wish for pre-Oedipal union. Isolde's Act I narrative locates the origin of her desire in the protagonists' mutual gaze at a traumatic moment. In this moment powerful and contrasting emotions converge, evoking thwarted developmental needs, and arousing the fantasy of redemption in love-death. By removing the magical elements, Wagner enables a deeper understanding of the characters' positions in relation to each other, each with his or her own needs for recognition and traumatic experiences. These positions invite mutual identifications resulting in rising tension between affirmation of identity and annihilation, with actual death as the only possible psychic solution. The dynamics described in the opera demonstrate the function of music and opera in conveying meaning which is not verbally expressible. Copyright © 2013 Institute of Psychoanalysis.

2011-12-28

The electronic conductivity of Ce(0.9)Gd(0.1)O(1.95-δ) and Ce(0.8)Pr(0.2)O(2-δ) under suppressed ionic flow was measured as a function of pO(2) in the range from 10(3) atm to 10(-17) atm for temperatures between 600 °C and 900 °C by means of Hebb-Wagner polarisation. The steady state I-V curve of Ce(0.9)Gd(0.1)O(1.95-δ) could be well described by the standard Hebb-Wagner equation [M. H. Hebb, J. Chem. Phys., 1952, 20, 185; C. Wagner, Z. Elektrochem., 1956, 60, 4], yielding expressions for the n- and p-type conductivity as a function of pO(2). On the other hand, significant deviation of the steady state I-V curve from the standard Hebb-Wagner equation was observed for the case of Ce(0.8)Pr(0.2)O(2-δ). It is shown that the I-V curve can be successfully reproduced when the presence of the redox active dopant, Pr(3+)/Pr(4+), is taken into account, whereas even better agreement can be reached when further taking into account the interference between the ionic and electronic flows [C. Chatzichristodoulou, W.-S. Park, H.-S. Kim, P. V. Hendriksen and H.-I. Yoo, Phys. Chem. Chem. Phys., 2010, 12, 33]. Expressions are deduced for the small polaron mobilities in the Ce 4f and Pr 4f bands of Ce(0.8)Pr(0.2)O(2-δ).

The St. Thomas East End Reserves or STEER is located on the southeastern end of the island of St. Thomas, USVI. The STEER contains extensive mangroves and seagrass beds, along with coral reefs, lagoons, and cays. Within the watershed, however, are a large active landfill, numerous marinas, resorts, various commercial activities, an EPA Superfund Site, and residential areas, all of which have the potential to contribute pollutants to the STEER. As part of a project to develop an integrated assessment for the STEER, 185 chemical contaminants were analyzed in sediments from 24 sites. Higher levels of chemical contaminants were found in Mangrove Lagoon and Benner Bay in the western portion of the study area. The concentrations of polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT), zinc, copper, lead, and mercury were above a NOAA Effects Range-Low (ERL) sediment quality guideline at one or more sites, indicating impacts may be present in more sensitive species or life stages. Copper at one site in Benner Bay was above a NOAA Effects Range-Median (ERM) guideline indicating effects on benthic organisms were likely. The antifoulant boat hull ingredient tributyltin (TBT) was found at the third highest concentration in the history of NOAA's National Status and Trends (NS&T) Program, which monitors the nation's coastal and estuarine waters for chemical contaminants and bioeffects. The results from this project will provide resource managers with key information needed to make effective decisions affecting coral reef ecosystem health and gauge the efficacy of restoration activities.

Locality of the Thomas-Fermi-von Weizsäcker Equations

NASA Astrophysics Data System (ADS)

Nazar, F. Q.; Ortner, C.

2017-06-01

We establish a pointwise stability estimate for the Thomas-Fermi-von Weiz-säcker (TFW) model, which demonstrates that a local perturbation of a nuclear arrangement results also in a local response in the electron density and electrostatic potential. The proof adapts the arguments for existence and uniqueness of solutions to the TFW equations in the thermodynamic limit by Catto et al. (The mathematical theory of thermodynamic limits: Thomas-Fermi type models. Oxford mathematical monographs. The Clarendon Press, Oxford University Press, New York, 1998). To demonstrate the utility of this combined locality and stability result we derive several consequences, including an exponential convergence rate for the thermodynamic limit, partition of total energy into exponentially localised site energies (and consequently, exponential locality of forces), and generalised and strengthened results on the charge neutrality of local defects.

Biomechanical consequences of callus development in Hoffmann, Wagner, Orthofix and Ilizarov external fixators.

PubMed

Juan, J A; Prat, J; Vera, P; Hoyos, J V; Sánchez-Lacuesta, J; Peris, J L; Dejoz, R; Alepuz, R

1992-09-01

A theoretical analysis by a finite elements model (FEM) of some external fixators (Hoffmann, Wagner, Orthofix and Ilizarov) was carried out. This study considered a logarithmic progress of callus elastic characteristics. A standard configuration of each fixator was defined where design and application characteristics were modified. A comparison among standard configurations and influence of every variation was made with regard to displacement and load transmission at the fracture site. An experimental evaluation of standard configurations was performed with a testing machine. After experimental validation of the theoretical model was achieved, an application of physiological loads which act on a fractured limb during normal gait was analysed. A minimal contribution from an external fixator to the total rigidity of the bone-callus-fixator system was assessed when a callus showing minimum elastic characteristics had just been established. Insufficient rigidity from the fixation devices to assure an adequate immobilization during the early stages of fracture healing was verified. However, regardless of the external fixator, callus development was the overriding element for the rigidity of the fixator-bone system.

Revised Thomas-Fermi approximation for singular potentials

NASA Astrophysics Data System (ADS)

Dufty, James W.; Trickey, S. B.

2016-08-01

Approximations for the many-fermion free-energy density functional that include the Thomas-Fermi (TF) form for the noninteracting part lead to singular densities for singular external potentials (e.g., attractive Coulomb). This limitation of the TF approximation is addressed here by a formal map of the exact Euler equation for the density onto an equivalent TF form characterized by a modified Kohn-Sham potential. It is shown to be a "regularized" version of the Kohn-Sham potential, tempered by convolution with a finite-temperature response function. The resulting density is nonsingular, with the equilibrium properties obtained from the total free-energy functional evaluated at this density. This new representation is formally exact. Approximate expressions for the regularized potential are given to leading order in a nonlocality parameter, and the limiting behavior at high and low temperatures is described. The noninteracting part of the free energy in this approximation is the usual Thomas-Fermi functional. These results generalize and extend to finite temperatures the ground-state regularization by R. G. Parr and S. Ghosh [Proc. Natl. Acad. Sci. U.S.A. 83, 3577 (1986), 10.1073/pnas.83.11.3577] and by L. R. Pratt, G. G. Hoffman, and R. A. Harris [J. Chem. Phys. 88, 1818 (1988), 10.1063/1.454105] and formally systematize the finite-temperature regularization given by the latter authors.

Dust acoustic solitary and shock excitations in a Thomas-Fermi magnetoplasma

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rahim, Z.; Qamar, A.; National Center for Physics

The linear and nonlinear properties of dust-acoustic waves are investigated in a collisionless Thomas-Fermi magnetoplasma, whose constituents are electrons, ions, and negatively charged dust particles. At dust time scale, the electron and ion number densities follow the Thomas-Fermi distribution, whereas the dust component is described by the classical fluid equations. A linear dispersion relation is analyzed to show that the wave frequencies associated with the upper and lower modes are enhanced with the variation of dust concentration. The effect of the latter is seen more strongly on the upper mode as compared to the lower mode. For nonlinear analysis, wemore » obtain magnetized Korteweg-de Vries (KdV) and Zakharov-Kuznetsov (ZK) equations involving the dust-acoustic solitary waves in the framework of reductive perturbation technique. Furthermore, the shock wave excitations are also studied by allowing dissipation effects in the model, leading to the Korteweg-de Vries-Burgers (KdVB) and ZKB equations. The analysis reveals that the dust-acoustic solitary and shock excitations in a Thomas-Fermi plasma are strongly influenced by the plasma parameters, e.g., dust concentration, dust temperature, obliqueness, magnetic field strength, and dust fluid viscosity. The present results should be important for understanding the solitary and shock excitations in the environments of white dwarfs or supernova, where dust particles can exist.« less

Limitations of the Porter-Thomas distribution

NASA Astrophysics Data System (ADS)

Weidenmüller, Hans A.

2017-12-01

Data on the distribution of reduced partial neutron widths and on the distribution of total gamma decay widths disagree with the Porter-Thomas distribution (PTD) for reduced partial widths or with predictions of the statistical model. We recall why the disagreement is important: The PTD is a direct consequence of the orthogonal invariance of the Gaussian Orthogonal Ensemble (GOE) of random matrices. The disagreement is reviewed. Two possible causes for violation of orthogonal invariance of the GOE are discussed, and their consequences explored. The disagreement of the distribution of total gamma decay widths with theoretical predictions cannot be blamed on the statistical model.

To report the clinical and molecular findings of a kindred with Wagner syndrome (WS) revealed by intraocular inflammatory features. Eight available family members underwent complete ophthalmologic examination, including laser flare cell meter measurements. Collagen, type II, alpha 1, versican (VCAN), frizzled family receptor 4, low density lipoprotein receptor-related protein 5, tetraspanin 12, and Norrie disease (pseudoglioma) genes were screened with direct sequencing. The index case was initially referred for unexplained severe and chronic postoperative bilateral uveitis following a standard cataract surgery procedure. Clinical examination of the proband revealed an optically empty vitreous with avascular vitreous strands and veils, features highly suggestive of WS. The systematic familial ophthalmologic examination identified three additional unsuspected affected family members who also presented with the WS phenotype, including uveitis for one of them. We identified a novel c.4004-6T>A nucleotide substitution at the acceptor splice site of intron 7 of the VCAN gene that segregated with the disease phenotype. We present a family with WS with typical WS features and intraocular inflammatory manifestations associated with a novel splice site VCAN mutation. Beyond the structural role in the retinal-vitreous architecture, versican is also emerging as a pivotal mediator of the inflammatory response, supporting uveitis predisposition as a clinical manifestation of WS.

Thomas Fincke (January 6th, 1561 - April 24th, 1650), born in Flensburg (Germany), was one of the very most important and significant scientists in Denmark during the seventeenth century, a mathematician and astrologer and physician in the beginning of modern science, a representative of humanism and an influentual academic organizer. He studied in Strasbourg (since 1577) and Padua (since 1583) and received his M.D. in Basel (1587), he practised as a physician throughtout his life (since 1587 or 1590) and became a professor at Copenhagen (1591). But he was best known because of his Geometriae rotundi libri XIIII (1583), a famous book on plane and spherical trigonometry, based not on Euclid but on Petrus Ramus. In this influentual work, in which Fincke introduced the terms tangent and secant and probable first noticed the Law of Tangents and the so-called Newton-Oppel-Mauduit-Simpson-Mollweide-Gauss-formula, he showed himself to be ,,abreast of the mathematics of his time".

Plant infested with herbivores, release volatile that can be used by natural enemies to locate their herbivorous prey. Laboratory studies were carried out to determine the olfactory responses of predator Macrolophus caliginosus Wagner (Heteroptera: Miridae), to chili plant infected with eggs, nymphs of Bemisia tabaci, using Y-tube olfactometer. The results shown that predator, M. caliginosus has ability to discriminate between non-infested and infested plant by B. tabaci. Moreover, the predator preferred plants with nymphs over plants with eggs. This suggested that M. caliginous uses whitefly-induced volatile as reliable indicators to distinguish between infested chili plants by nymphs, eggs and non-infested plants. These results enhance our understanding of the olfactory cues that guide foraging by M. caliginosus to plant with and without Bemisia tabaci.

Determinants of female dispersal in Thomas langurs.

PubMed

Sterck, E H

1997-01-01

Female dispersal occurs in a number of primate species. It may be related to: avoidance of inbreeding, reduction in food competition, reduction of predation risk, or avoidance of infanticide in combination with mate choice. Female dispersal was studied for a 5-year period in a wild population of Thomas langurs (Presbytis thomasi) that lived in one-male multi-female groups. Juvenile and adult individuals of both sexes were seen to disperse. Females appeared to transfer unhindered between groups, mostly from a larger group to a recently formed smaller one. They transferred without their infants and when not pregnant, and seemed to transfer preferentially during periods when extra-group males were harassing their group. During these inter-group encounters extra-group males seemed to try to commit infanticide. Thus, the timing of female transfer was probably closely linked to infanticide avoidance. Moreover, females seemed to transfer when the resident male of their group was no longer a good protector. The observations in the present study suggest that females transferred to reduce the risk of infanticide. Female dispersal may have another ultimate advantage as well, namely inbreeding avoidance. Due to the dispersal of both females and males the social organization of Thomas langurs was rather fluid. New groups were formed when females joined a male; male takeovers were not observed. Bisexual groups had only a limited life span, because all adult females of a bisexual group could emigrate. This pattern of unhindered female dispersal affects male reproductive strategies, and in particular it might lead to infanticidal behavior during inter-group encounters.

To tell the story of Thomas Bessell Kidner and his impact on occupational therapy. Interpretive biography research methods using archival materials, published papers and family papers. Kidner's work as an organizer of manual training in elementary schools in Nova Scotia and New Brunswick and as Director of Technical Education for Calgary prepared him for his work as Vocational Secretary of the Military Hospitals Commission during World War I. Kidner developed, implemented and oversaw the reeducation program for injured soldiers across Canada. It included bedside occupations, off-ward and curative workshop activities provided by ward aides, as well as industrial training and apprenticeships in the workplace. Kidner's story stimulates us to revisit our profession's early emphasis on return-to-work. Knowing about our past helps occupational therapists to build a stronger identity.

Porter-Thomas distribution in unstable many-body systems

Volya, Alexander

We use the continuum shell model approach to explore the resonance width distribution in unstable many-body systems. The single-particle nature of a decay, the few-body character of the interaction Hamiltonian, and the collectivity that emerges in nonstationary systems due to the coupling to the continuum of reaction states are discussed. Correlations between the structures of the parent and daughter nuclear systems in the common Fock space are found to result in deviations of decay width statistics from the Porter-Thomas distribution.

Trial densities for the extended Thomas-Fermi model

1996-02-01

A new and simplified form of nuclear densities is proposed for the extended Thomas-Fermi method (ETF) and applied to calculate the ground-state properties of several spherical nuclei, with results comparable or even better than other conventional density profiles. With the expectation value method (EVM) for microscopic corrections we checked our new densities for spherical nuclei. The binding energies of ground states almost reproduce the Hartree-Fock (HF) calculations exactly. Further applications to nuclei far away from the β-stability line are discussed.

Quasi-four-body treatment of charge transfer in the collision of protons with atomic helium: I. Thomas related mechanisms

2018-04-01

The scattering of a completely bare ion by atoms larger than hydrogen is at least a four-body interaction, and the charge transfer channel involves a two-step process. Amongst the two-step interactions of the high-velocity single charge transfer in an anion-atom collision, there is one whose amplitude demonstrates a peak in the angular distribution of the cross sections. This peak, the so-called Thomas peak, was predicted by Thomas in a two-step interaction, classically, which could also be described through three-body quantum mechanical models. This work discusses a four-body quantum treatment of the charge transfer in ion-atom collisions, where two-step interactions illustrating a Thomas peak are emphasized. In addition, the Pauli exclusion principle is taken into account for the initial and final states as well as the operators. It will be demonstrated that there is a momentum condition for each two-step interaction to occur in a single charge transfer channel, where new classical interactions lead to the Thomas mechanism.

Small polaronic hole hopping mechanism and Maxwell-Wagner relaxation in NdFeO3

NASA Astrophysics Data System (ADS)

Ahmad, I.; Akhtar, M. J.; Younas, M.; Siddique, M.; Hasan, M. M.

2012-10-01

In the modern micro-electronics, transition metal oxides due to their colossal values of dielectric permittivity possess huge potential for the development of capacitive energy storage devices. In the present work, the dielectric permittivity and the effects of temperature and frequency on the electrical transport properties of polycrystalline NdFeO3, prepared by solid state reaction method, are discussed. Room temperature Mossbauer spectrum confirms the phase purity, octahedral environment for Fe ion, and high spin state of Fe3+ ion. From the impedance spectroscopic measurements, three relaxation processes are observed, which are related to grains, grain boundaries (gbs), and electrode-semiconductor contact in the measured temperature and frequency ranges. Decrease in resistances and relaxation times of the grains and grain boundaries with temperature confirms the involvement of thermally activated conduction mechanisms. Same type of charge carriers (i.e., small polaron hole hopping) have been found responsible for conduction and relaxation processes through the grain and grain boundaries. The huge value of the dielectric constant (˜8 × 103) at high temperature and low frequency is correlated to the Maxwell-Wagner relaxation due to electrode-sample contact.

Optical Thomas-Reiche-Kuhn sum rules.

2012-01-06

The Thomas-Reiche-Kuhn sum rule is a fundamental consequence of the position-momentum commutation relation for an atomic electron and it provides an important constraint on the transition matrix elements for an atom. Analogously, the commutation relations for the electromagnetic field operators in a magnetodielectric medium constrain the properties of the dispersion relations for the medium through four sum rules for the allowed phase and group velocities for polaritons propagating through the medium. These rules apply to all bulk media including the metamaterials designed to provide negative refractive indices. An immediate consequence of this is that it is not possible to construct a medium in which all the polariton modes for a given wavelength lie in the negative-index region.

Thomas Young's investigations in gradient-index optics.

PubMed

Atchison, David A; Charman, W Neil

2011-05-01

James Clerk Maxwell is usually recognized as being the first, in 1854, to consider using inhomogeneous media in optical systems. However, some 50 years earlier, Thomas Young, stimulated by his interest in the optics of the eye and accommodation, had already modeled some applications of gradient-index optics. These applications included using an axial gradient to provide spherical aberration-free optics and a spherical gradient to describe the optics of the atmosphere and the eye lens. We evaluated Young's contributions. We attempted to derive Young's equations for axial and spherical refractive index gradients. Raytracing was used to confirm accuracy of formula. We did not confirm Young's equation for the axial gradient to provide aberration-free optics but derived a slightly different equation. We confirmed the correctness of his equations for deviation of rays in a spherical gradient index and for the focal length of a lens with a nucleus of fixed index surrounded by a cortex of reducing index toward the edge. Young claimed that the equation for focal length applied to a lens with part of the constant index nucleus of the sphere removed, such that the loss of focal length was a quarter of the thickness removed, but this is not strictly correct. Young's theoretical work in gradient-index optics received no acknowledgment from either his contemporaries or later authors. Although his model of the eye lens is not an accurate physiological description of the human lens, with the index reducing least quickly at the edge, it represented a bold attempt to approximate the characteristics of the lens. Thomas Young's work deserves wider recognition.

Warm ''pasta'' phase in the Thomas-Fermi approximation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Avancini, Sidney S.; Menezes, Debora P.; Chiacchiera, Silvia

In the present article, the 'pasta' phase is studied at finite temperatures within a Thomas-Fermi (TF) approach. Relativistic mean-field models, both with constant and density-dependent couplings, are used to describe this frustrated system. We compare the present results with previous ones obtained within a phase-coexistence description and conclude that the TF approximation gives rise to a richer inner ''pasta'' phase structure and the homogeneous matter appears at higher densities. Finally, the transition density calculated within TF is compared with the results for this quantity obtained with other methods.

This article attempts to contribute to the debate on the future of epidemiology by combining Thomas Kuhn's ideas on scientific paradigms with the author's observations on some epidemiology textbooks. The author's interpretations were based on his readings of Kuhn's The Structure of Scientific Revolutions, epidemiology textbooks, and papers on the future of epidemiology. Thomas Kuhn's view is that sciences mostly work with a single paradigm driven by exemplars of successful work, and that proposals for paradigm change are resisted. Sciences that are maturing or changing do not have a dominant paradigm. Epidemiology textbooks showed diversity in their concepts, content, and approach. Most exemplars related to etiologic research rather than public health practice. One key focus of the recent controversy regarding the role of epidemiology has been the increasing inability of epidemiology to solve socially based public health problems. Kuhn's views help explain the polarization of views expressed. Kuhn's philosophy of science offers insights into controversies such as whether a paradigm shift is needed or imminent and the gap between epidemiology and public health practice. Interaction between science philosophers, epidemiologists, and public health practitioners may be valuable. PMID:10432899

Parallel Directionally Split Solver Based on Reformulation of Pipelined Thomas Algorithm

NASA Technical Reports Server (NTRS)

Povitsky, A.

1998-01-01

In this research an efficient parallel algorithm for 3-D directionally split problems is developed. The proposed algorithm is based on a reformulated version of the pipelined Thomas algorithm that starts the backward step computations immediately after the completion of the forward step computations for the first portion of lines This algorithm has data available for other computational tasks while processors are idle from the Thomas algorithm. The proposed 3-D directionally split solver is based on the static scheduling of processors where local and non-local, data-dependent and data-independent computations are scheduled while processors are idle. A theoretical model of parallelization efficiency is used to define optimal parameters of the algorithm, to show an asymptotic parallelization penalty and to obtain an optimal cover of a global domain with subdomains. It is shown by computational experiments and by the theoretical model that the proposed algorithm reduces the parallelization penalty about two times over the basic algorithm for the range of the number of processors (subdomains) considered and the number of grid nodes per subdomain.

Between 1891 and 1893 the famous Austrian and German neuropsychiatrists Julius Wagner-Jauregg and Paul Julius Möbius disputed in leading German and Austrian medical journals about mental and physiological changes and symptoms in people who after strangulation could be revived in time to survive. Their dispute even touched personal issues. For the study, the original sources were studied and contrasted with relevant secondary sources. The dispute was mainly about two opposing concepts: On the one hand, Wagner-Jauregg supported an organic, neurological concept; on the other hand a psychoreactive-symptoms concept represented by Möbius and elaborated by him first in his concept of hysteria. The study elaborates these factual differences in completely different approaches to psychiatry and - at least in the case of Möbius - how a medical theory was embedded into a pre-existing philosophical system. The dispute studied discusses a philosophical problem which has remained incompletely understood until the present day - the relationship of body and mind. Hence the study on this dispute is more than just an interesting aspect in the history of sciences, but rather the illustration of a meeting of two opponents in a still relevant discussion. © Georg Thieme Verlag KG Stuttgart · New York.

Thomas-Fermi simulations of dense plasmas without pseudopotentials

NASA Astrophysics Data System (ADS)

Starrett, C. E.

2017-07-01

The Thomas-Fermi model for warm and hot dense matter is widely used to predict material properties such as the equation of state. However, for practical reasons current implementations use pseudopotentials for the electron-nucleus interaction instead of the bare Coulomb potential. This complicates the calculation and quantities such as free energy cannot be converged with respect to the pseudopotential parameters. We present a method that retains the bare Coulomb potential for the electron-nucleus interaction and does not use pseudopotentials. We demonstrate that accurate free energies are obtained by checking variational consistency. Examples for aluminum and iron plasmas are presented.

The electrostatic interaction between two charged particles is strongly modified in the vicinity of a metal. This situation is usually accounted for by the celebrated image charges approach, which was further extended to account for the electronic screening properties of the metal at the level of the Thomas-Fermi description. In this paper we build upon the approach by [Kornyshev et al. Zh. Eksp. Teor. Fiz., 78(3):1008–1019, 1980] and successive works to calculate the 1-body and 2-body electrostatic energy of ions near a metal in terms of the Thomas-Fermi screening length. We propose workable approximations suitable for molecular simulations of ionic systems close to metallic walls. Furthermore, we use this framework to calculate analytically the electrostatic contribution to the surface energy of a one dimensional crystal at a metallic wall and its dependence on the Thomas-Fermi screening length. These calculations provide a simple interpretation for the surface energy in terms of image charges, which allow for an estimate of interfacial properties in more complex situations of a disordered ionic liquid close to a metal surface. A counterintuitive outcome is that electronic screening, as characterized by a molecular Thomas-Fermi length ℓTF, profoundly affects the wetting of ionic systems close to a metal, in line with the recent experimental observation of capillary freezing of ionic liquids in metallic confinement.

Although there is growing evidence to suggest that magnesium supplementation to patients undergoing cardiac surgery is beneficial, the way to administer magnesium is not established. Moreover in Japan St Thomas' cardioplegic solution, containing a high level of magnesium is widely used and the effect of such magnesium-rich cardioplegic solutions on blood magnesium concentration has not been well defined. We measured ionized magnesium concentrations (iMg) during cardiac surgery employing St Thomas' solution. Patients were divided into four groups. Group 1 patients were adults and group 2 were children, both of whom received St. Thomas' solution. Group 3 patients underwent cardiopulmonary bypass but did not receive any cardioplegic solution. Group 4 patients underwent off-pump coronary artery bypass grafting. In cardioplegia group (group 1 and 2) iMg was higher than the normal reference range at periods of rewarming, immediately postbypass, and at the end of the operation. iMg at immediately postbypass was related to the total amount of cardioplegic solution. In non-cardioplegia group (group 3 and 4) progressive decrease of iMg was observed throughout the operation. Because magnesium in cardioplegic solutions has substantial effect on perioperative iMg, it is crucial to measure iMg to avoid overdose of magnesium when magnesium-rich cardioplegic solutions are employed.

Heat Flow Budget of the Gulf of California Rift: Preliminary Results of a High Resolution Survey Across the Wagner Basin

NASA Astrophysics Data System (ADS)

Negrete-Aranda, R.; Neumann, F.; Harris, R. N.; Contreras, J.; Gonzalez-Fernandez, A.; Sclater, J. G.

2016-12-01

The thermal regime exerts a primary control on rift dynamics and mode of extension for continental lithosphere. We present three heat-flow profiles across the southern terminus of the Cerro Prieto fault, in the northern Gulf of California. The longest profile is 42 km and has a measurement spacing of 1 km that spans the hanging-wall block (Wagner basin) and the footwall block of that fault. Measurements were taken with a 6.5 m long Fielax, violin-bow probe. Most measurements are of good quality, i.e., the probe fully penetrated sediments and measurements were stable enough to perform reliable inversion for heat flow and thermal properties. However, it was necessary to perform numerous corrections due to environmental phenomena related the copious sedimentation in the area, and seasonal changes in water temperature. Our measurements indicate the total throughput across the central rift and its east shoulder is 15 KW/m per meter of rift length. More important, heat flow values cluster in three distinct spatial groups: (i) heat flow in the well sedimented depocenter of the Wagner basin is approximately 200 mW/m2; (ii) the footwall block heat-flow is approximately 400 mW/m2; and (iii) heat flow across the fault zone is very high, up to 5,000 mW/m2. Our interpretation is that the former value represents the background conductive heat flow in the rift whereas heat flow across the fault represents advective heat transport by hydrothermal fluids. The high heat flow in the footwall block of the Cerro Prieto fault might be result of both conductive and advective heat transfer by fluid seepage from the basin. These data provide evidence that fluids from deep magma bodies transported along faults assist rifting in the northern Gulf of California. We are exploring how fluids may play a role in weakening the lithosphere and help localizing/delocalizing strain along major transforms and numerous normal faults observed in the area.

Systematic heat flow measurements across the Wagner Basin, northern Gulf of California

2017-12-01

A primary control on the geodynamics of rifting is the thermal regime. To better understand the geodynamics of rifting in the northern Gulf of California we systematically measured heat-flow across the Wagner Basin, a tectonically active basin that lies near the southern terminus of the Cerro Prieto fault. The heat flow profile is 40 km long, has a nominal measurement spacing of ∼1 km, and is collocated with a seismic reflection profile. Heat flow measurements were made with a 6.5-m violin-bow probe. Although heat flow data were collected in shallow water, where there are significant temporal variations in bottom water temperature, we use CTD data collected over many years to correct our measurements to yield accurate values of heat flow. After correction for bottom water temperature, the mean and standard deviation of heat flow across the western, central, and eastern parts of the basin are 220 ± 60, 99 ± 14, 889 ± 419 mW m-2, respectively. Corrections for sedimentation would increase measured heat flow across the central part of basin by 40 to 60%. We interpret the relatively high heat flow and large variability on the western and eastern flanks in terms of upward fluid flow at depth below the seafloor, whereas the lower and more consistent values across the central part of the basin are suggestive of conductive heat transfer. Moreover, heat flow across the central basin is consistent with gabbroic underplating at a depth of 15 km and suggests that continental rupture here has not gone to completion.

Thomas K. Jeffers has made many significant contributions to our understanding of the biology of the parasite Eimeria, the cause of coccidiosis in poultry. His work has had direct practical application for the control of this widespread disease. Topics discussed include Jeffers' pioneering work concerned with genetics of the host response to infection, the nature of biological and immunological intraspecific variation, drug resistance and discovery, field surveys of resistance, and his most recognized achievement-the demonstration that the lifecycle of coccidia may be altered by artificial selection. Parasites so modified are attenuated but retain their immunogenicity, a discovery that has led to the development of live vaccines that are inherently non-pathogenic. This article provides a brief biography and describes the contributions that Jeffers has made to our knowledge of coccidiosis.

Objective To understand the bacterial profile and antibiotic resistance patterns in diabetic foot infection (DFI) in different Wagner's grades, IDSA/IWGDF grades, and different ulcer types in Guangzhou, in order to provide more detailed suggestion to the clinician about the empirical antibiotic choice. Methods 207 bacteria were collected from 117 DFIs in Sun Yat-sen Memorial Hospital from Jan.1, 2010, to Dec.31, 2015. The clinical data and microbial information were analyzed. Results The proportion of Gram-negative bacteria (GNB) was higher than Gram-positive bacteria (GPB) (54.1% versus 45.9%), in which Enterobacteriaceae (73.2%) and Staphylococcus (65.2%) were predominant, respectively. With an increasing of Wagner's grades and IDSA/IWGDF grades, the proportion of GNB bacterial infection, especially Pseudomonas, was increased. Neuro-ischemic ulcer (N-IFU) was more susceptible to GNB infection. Furthermore, with the aggravation of the wound and infection, the antibiotic resistance rates were obviously increased. GPB isolated in ischemic foot ulcer (IFU) showed more resistance than the N-IFU, while GNB isolates were on the opposite. Conclusions Different bacterial profiles and antibiotic sensitivity were found in different DFU grades and types. Clinician should try to stay updated in antibiotic resistance pattern of common pathogens in their area. This paper provided them the detailed information in this region. PMID:29075293

He was the California Institute of Technology's Fletcher Jones Professor of Geophysics, emeritus since 2005 but professionally active to the end. He had been president of AGU's Tectonophysics section, editor of Journal of Geophysical Research, founding member of both the Mineral and Rock Physics and Study of the Earth's Deep Interior focus groups, and editor—more like key driving force—for AGU's Handbook of Physical Constants. Tom was a pioneer in experimental and numerical studies of the effects of projectiles hitting a target at velocities exceeding the speed of sound (hypervelocity impact), arguably the most important geophysical process in the formation, growth, and, in many cases, surface evolution of planets. As a professor at Caltech, he established the foremost university laboratory for shock wave experiments, where students and research associates from around the world pursued basic research in geophysics, planetary science, and other disciplines. Previously, high-pressure shock experiments were conducted primarily in national laboratories, where they were initially associated with the development of nuclear weapons.

This NREL technical report utilizes a development framework originated by NREL and known by the acronym SROPTTC to assist the U.S. Virgin Islands in identifying and understanding concrete opportunities for wind power development in the territory. The report covers each of the seven components of the SROPTTC framework: Site, Resource, Off-take, Permitting, Technology, Team, and Capital as they apply to wind power in the USVI and specifically to a site in Bovoni, St. Thomas. The report concludes that Bovoni peninsula is a strong candidate for utility-scale wind generation in the territory. It represents a reasonable compromise in terms of windmore » resource, distance from residences, and developable terrain. Hurricane risk and variable terrain on the peninsula and on potential equipment transport routes add technical and logistical challenges but do not appear to represent insurmountable barriers. In addition, integration of wind power into the St. Thomas power system will present operational challenges, but based on experience in other islanded power systems, there are reasonable solutions for addressing these challenges.« less

2018-04-09

Nutrients and sedimentation were monitored for approximately 2 years at six sites in the St. Thomas East End Reserves (STEER), St. Thomas, USVI, as part of a NOAA project to develop an integrated environmental assessment. Concentrations of ammonium (NH 4 + ) and dissolved inorganic nitrogen (DIN) were higher in Mangrove Lagoon and Benner Bay in the western portion of STEER than in the other sites further east (i.e., Cowpet Bay, Rotto Cay, St. James, and Little St. James). There was no correlation between rainfall and nutrient concentrations. Using a set of suggested nutrient thresholds that have been developed to indicate the potential for the overgrowth of algae on reefs, approximately 60% of the samples collected in STEER were above the threshold for orthophosphate (HPO 4 = ), while 55% of samples were above the DIN threshold. Benner Bay had the highest sedimentation rate of any site monitored in STEER, including Mangrove Lagoon. There was also an east to west and a north to south gradient in sedimentation, indicative of higher sedimentation rates in the western, more populated areas surrounding STEER, and sites closer to the shore of the main island of St. Thomas. Although none of the sites had a mean or average sedimentation rate above a suggested sedimentation threshold, the mean sedimentation rate in Benner Bay was just below the threshold.

Time-Dependent Thomas-Fermi Approach for Electron Dynamics in Metal Clusters

Domps, A.; Reinhard, P.-G.; Suraud, E.

1998-06-01

We propose a time-dependent Thomas-Fermi approach to the (nonlinear) dynamics of many-fermion systems. The approach relies on a hydrodynamical picture describing the system in terms of collective flow. We investigate in particular an application to electron dynamics in metal clusters. We make extensive comparisons with fully fledged quantal dynamical calculations and find overall good agreement. The approach thus provides a reliable and inexpensive scheme to study the electronic response of large metal clusters.

Giant dielectric constant dominated by Maxwell-Wagner relaxation in Al{sub 2}O{sub 3}/TiO{sub 2} nanolaminates synthesized by atomic layer deposition.

Nanolaminates consisting of Al{sub 2}O{sub 3} and TiO{sub 2} oxide sublayers were synthesized by using atomic layer deposition to produce individual layers with atomic scale thickness control. The sublayer thicknesses were kept constant for each multilayer structure, and were changed from 50 to 0.2 nm for a series of different samples. Giant dielectric constant ({approx}1000) was observed when the sublayer thickness is less than 0.5 nm, which is significantly larger than that of Al{sub 2}O{sub 3} and TiO{sub 2} dielectrics. Detailed investigation revealed that the observed giant dielectric constant is originated from the Maxwell-Wagner type dielectric relaxation.

Partial genome segments of a begomovirus were previously amplified from Wissadula amplissima exhibiting yellow-mosaic and leaf-curl symptoms in the parish of St. Thomas, Jamaica and this isolate assigned to a tentative begomovirus species, Wissadula golden mosaic St. Thomas virus. To clone the complete genome of this isolate of Wissadula golden mosaic St. Thomas virus, abutting primers were designed to PCR amplify its full-length DNA-A and DNA-B components. Sequence analysis of the complete begomovirus genome obtained, confirmed that it belongs to a distinct begomovirus species and this isolate was named Wissadula golden mosaic St. Thomas virus-[Jamaica:Albion:2005] (WGMSTV-[JM:Alb:05]). The genome of WGMSTV-[JM:Alb:05] is organized similar to that of other bipartite Western Hemisphere begomoviruses. Phylogenetic analyses placed the genome components of WGMSTV-[JM:Alb:05] in the Abutilon mosaic virus clade and showed that the DNA-A component is most closely related to four begomovirus species from Cuba, Tobacco leaf curl Cuba virus, Tobacco leaf rugose virus, Tobacco mottle leaf curl virus, and Tomato yellow distortion leaf virus. The putative Rep-binding-site motif in the common region of WGMSTV-[JM:Alb:05] was observed to be identical to that of Chino del tomate virus-Tomato [Mexico:Sinaloa:1983], Sida yellow mosaic Yucatan virus-[Mexico:Yucatan:2005], and Tomato leaf curl Sinaloa virus-[Nicaragua:Santa Lucia], suggesting that WGMSTV-[JM:Alb:05] is capable of forming viable pseudo-recombinants with these begomoviruses, but not with other members of the Abutilon mosaic virus clade. Biolistic inoculation of test plant species with partial dimers of the WGMSTV-[JM:Alb:05] DNA-A and DNA-B components showed that the virus was infectious to Nicotiana benthamiana and W. amplissima and the cultivated species Phaseolus vulgaris (kidney bean) and Lycopersicon esculentum (tomato). Infected W. amplissima plants developed symptoms similar to symptoms observed under field

Mermin-Wagner theorem, flexural modes, and degraded carrier mobility in two-dimensional crystals with broken horizontal mirror symmetry

NASA Astrophysics Data System (ADS)

Fischetti, Massimo V.; Vandenberghe, William G.

2016-04-01

We show that the electron mobility in ideal, free-standing two-dimensional "buckled" crystals with broken horizontal mirror (σh) symmetry and Dirac-like dispersion (such as silicene and germanene) is dramatically affected by scattering with the acoustic flexural modes (ZA phonons). This is caused both by the broken σh symmetry and by the diverging number of long-wavelength ZA phonons, consistent with the Mermin-Wagner theorem. Non-σh-symmetric, "gapped" 2D crystals (such as semiconducting transition-metal dichalcogenides with a tetragonal crystal structure) are affected less severely by the broken σh symmetry, but equally seriously by the large population of the acoustic flexural modes. We speculate that reasonable long-wavelength cutoffs needed to stabilize the structure (finite sample size, grain size, wrinkles, defects) or the anharmonic coupling between flexural and in-plane acoustic modes (shown to be effective in mirror-symmetric crystals, like free-standing graphene) may not be sufficient to raise the electron mobility to satisfactory values. Additional effects (such as clamping and phonon stiffening by the substrate and/or gate insulator) may be required.

Systematic Heat Flow Measurements Across the Wagner Basin, Northern Gulf of California

Neumann, F.; Negrete-Aranda, R.; Harris, R. N.; Contreras, J.; Sclater, J. G.; Gonzalez-Fernandez, A.

2017-12-01

A primary control on the geodynamics of rifting is the thermal regime. To better understand the geodynamics of rifting in the northern Gulf of California we systematically measured heat-flow across the Wagner Basin, a tectonically active basin that lies near the southern terminus of the Cerro Prieto fault. Seismic reflection profiles show sediment in excess of 5 s two-way travel time, implying a sediment thickness of > 7 km. The heat flow profile is 40 km long, has a nominal measurement spacing of 1 km, and is collocated with a seismic reflection profile. Heat flow measurements were made with a 6.5-m violin-bow probe. Most measurements are of good quality in that the probe fully penetrated sediments and measurements were stable enough to invert for heat flow and thermal properties. We have estimated corrections for environmental perturbations due to changes in bottom water temperature and sedimentation. The mean and standard deviation of heat flow across the western, central, and eastern parts of the basin are 220±60, 99±14, 1058±519 mW m-2, respectively. Corrections for sedimentation would increase measured heat flow across the central part of basin by 40 to 60%. We interpret the relatively high heat flow and large variability on the western and eastern flanks in terms of upward fluid flow at depth below the seafloor, whereas the lower and more consistent values across the central part of the basin are suggestive of conductive heat transfer. Based on an observed fault depth of 1.75 km we estimated the maximum Darcy velocities through the western and eastern flanks as 3 and 10 cm yr-1, respectively. Heat flow across the central basin is consistent with gabbroic underplating at a depth of 15 km and suggests that continental rupture here has not gone to completion.

Discussion on the energy content of the galactic dark matter Bose-Einstein condensate halo in the Thomas-Fermi approximation

De Souza, J.C.C.; Pires, M.O.C., E-mail: jose.souza@ufabc.edu.br, E-mail: marcelo.pires@ufabc.edu.br

We show that the galactic dark matter halo, considered composed of an axionlike particles Bose-Einstein condensate [6] trapped by a self-graviting potential [5], may be stable in the Thomas-Fermi approximation since appropriate choices for the dark matter particle mass and scattering length are made. The demonstration is performed by means of the calculation of the potential, kinetic and self-interaction energy terms of a galactic halo described by a Boehmer-Harko density profile. We discuss the validity of the Thomas-Fermi approximation for the halo system, and show that the kinetic energy contribution is indeed negligible.

STS-114 Mission Specialists, Andy Thomas and Steve Robinson, are seen in this pre-flight interview. Andy Thomas begins by talking about his interest in spaceflight as a young boy growing up in Australia. He expresses that the chances of an Australian boy studying to eventually become an astronaut was very remote. His Mechanical Engineering Degree in Australia and a Doctorate enabled him to acquire unique skills to come to the United States to work for Lockheed Martin. On the topic of return to flight, he reflects on experiences that he had working with the Michael Anderson and Kalpana Chawla of the ill-fated Space Shuttle Columbia. He also talks about the safety of the Space Shuttle Discovery and repairs to its Thermal Protection system. He explains in detail the Logistics Flight (LF) 1, spacewalks, Multipurpose Logistics Module (MPLM) and the External Stowage Platform (ESP)-2. Steve Robinson expresses that he had many interests as a child and becoming an astronaut was one of them. He was fascinated with things that fly and wanted to find out how they flew. He also designed hang gliders as a teenager. He expresses how his family feels about the risky business of spaceflight. He talks about how the space shuttle discovery crew will remember the Columbia crew by including seven stars on their patch so that they can bring them into orbit and then back home. Robinson also talks about his primary job, and the spacewalks that he and Soichi Noguchi will be performing.

Constraints on the nuclear equation of state from nuclear masses and radii in a Thomas-Fermi meta-modeling approach

NASA Astrophysics Data System (ADS)

Chatterjee, D.; Gulminelli, F.; Raduta, Ad. R.; Margueron, J.

2017-12-01

The question of correlations among empirical equation of state (EoS) parameters constrained by nuclear observables is addressed in a Thomas-Fermi meta-modeling approach. A recently proposed meta-modeling for the nuclear EoS in nuclear matter is augmented with a single finite size term to produce a minimal unified EoS functional able to describe the smooth part of the nuclear ground state properties. This meta-model can reproduce the predictions of a large variety of models, and interpolate continuously between them. An analytical approximation to the full Thomas-Fermi integrals is further proposed giving a fully analytical meta-model for nuclear masses. The parameter space is sampled and filtered through the constraint of nuclear mass reproduction with Bayesian statistical tools. We show that this simple analytical meta-modeling has a predictive power on masses, radii, and skins comparable to full Hartree-Fock or extended Thomas-Fermi calculations with realistic energy functionals. The covariance analysis on the posterior distribution shows that no physical correlation is present between the different EoS parameters. Concerning nuclear observables, a strong correlation between the slope of the symmetry energy and the neutron skin is observed, in agreement with previous studies.

Disease is more than dysfunctional organs, morphological abnormalities and genetic divergence. It is also about existence, self-conception and social identity.

The Thomas Jefferson National Accelerator Facility (Jefferson Lab) in Newport News, Virginia, USA, is one of ten national laboratories under the aegis of the Office of Science of the U.S. Department of Energy (DOE). It is managed and operated by Jefferson Science Associates, LLC. The primary facility at Jefferson Lab is the Continuous Electron Beam Accelerator Facility (CEBAF) as shown in an aerial photograph in Figure 1. Jefferson Lab was created in 1984 as CEBAF and started operations for physics in 1995. The accelerator uses superconducting radio-frequency (srf) techniques to generate high-quality beams of electrons with high-intensity, well-controlled polarization. Themore » technology has enabled ancillary facilities to be created. The CEBAF facility is used by an international user community of more than 1200 physicists for a program of exploration and study of nuclear, hadronic matter, the strong interaction and quantum chromodynamics. Additionally, the exceptional quality of the beams facilitates studies of the fundamental symmetries of nature, which complement those of atomic physics on the one hand and of high-energy particle physics on the other. The facility is in the midst of a project to double the energy of the facility and to enhance and expand its experimental facilities. Studies are also pursued with a Free-Electron Laser produced by an energy-recovering linear accelerator.« less

Green leviathan? Thomas hobbes, joel bakan and Arnold schwarzenegger.

PubMed

Evans, Robert G

2007-02-01

Thomas Hobbes postulates that men are driven by "a perpetual and restless desire of power after power, that ceaseth only in death." The miserable consequences of this drive for power and the competing "desire of ease and sensual delight" and "fear of death and wounds" lead them to establish and obey. Substituting "profit" for "power" yields a description of the modern corporation, but without the desires or fears of natural persons. Such "unnatural persons" lack the Hobbesian ground of obligation, yet have appropriated the privileges and protections of natural persons. They challenge or undermine the sovereign wherever it limits their profits. Governor Schwarzenegger's re-election in California, however, on a strong anti-CO(2) program, suggests a willingness by threatened natural persons to re-empower Leviathan.

Application of the Maxwell-Wagner-Hanai effective medium theory to the analysis of the interfacial polarization relaxations in conducting composite films

J-P Adohi, B.; Vanga Bouanga, C.; Fatyeyeva, K.; Tabellout, M.

2009-01-01

A new approach to explain the interfacial polarization phenomenon in conducting composite films is proposed. HCl-doped poly(ethylene terephthalate) (PET) and polyamide-6 (PA-6) matrices with embedded polyaniline (PANI) particles as filler were investigated and analysed, combining dielectric spectroscopy and AFM electrical images with the effective medium theory analysis. Up to three relaxation peaks attributed to the interfacial polarization phenomena were detected in the studied frequency range (0.1 Hz-1 MHz). The AFM electrical images revealed that the doped PA-6/PANI composite can be modelled as a single-type particle medium and the PET/PANI one as a two-type particle medium. A simple dielectric loss expression was derived from the Maxwell-Wagner-Hanai mixture equation and was applied to the experimental data to identify the interfaces involved in each of the relaxation peaks. The parameter values (permittivity, conductivity, volume fraction of the PANI particles) were found to agree well with the measured one, hence validating the models.

The light bulb, cystoscopy, and Thomas Alva Edison.

PubMed

Moran, Michael E

2010-09-01

Thomas Alva Edison was an icon of American achievement who literally invented the 20th century. Although best known as the inventor of the electric light bulb, the phonograph, and motion pictures, he also left a lasting legacy via peripheral developmental applications, such as endoscopes. A review of published urologic writings about incandescent cystoscopes was cross-referenced to writings about or from Edison. Important events that allowed transference of technology from the Edison laboratory to clinical practice were emphasized. Edison was born in 1847 while Lincoln was serving in Congress; he died in 1931 when Hoover struggled with the Great Depression. Edison's life spanned the formative period of America that Henry Adams called the "coming of age." Edison received a Sprengel vacuum device in late 1879, and as usual, he was able to tweak the machine to better performance. For 5 days in October, 16 to 21, he improved the vacuum from 1/100,000 to 1/1,000,000 atm, and his first incandescent bulb burned softly. On December 21, 1879, he leaked the story to N.Y. Herald journalist Marshall Fox, and the world was notified of the light bulb. Special Christmas light visits started in Menlo Park just 4 days later. Edison patented the screw cap for easy changes, and the first bulbs sold for 40 cents (cost $1.40). 100,000 bulbs sold in 1882, 4 million by 1892, and 45 million in 1903. Immediately, competitors and specialty manufacturers entered the market. Dr. Henry Koch and Charles Preston in Rochester, N.Y., developed a smaller, low amperage bulb that could be fitted to medical devices. No discussion of electricity and modern applications would be complete without some discussion of Thomas Alva Edison and his sentinel contributions. The first church, post office, and ship were illuminated in 1892. The first hotel, theater, and electric sign were in 1893. The rapidity of dispersal and secondary applications of Edison's inventions is typified by the rise of cystoscopes

On Raviart-Thomas and VMS formulations for flow in heterogeneous materials.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Turner, Daniel Zack

It is well known that the continuous Galerkin method (in its standard form) is not locally conservative, yet many stabilized methods are constructed by augmenting the standard Galerkin weak form. In particular, the Variational Multiscale (VMS) method has achieved popularity for combating numerical instabilities that arise for mixed formulations that do not otherwise satisfy the LBB condition. Among alternative methods that satisfy local and global conservation, many employ Raviart-Thomas function spaces. The lowest order Raviart-Thomas finite element formulation (RT0) consists of evaluating fluxes over the midpoint of element edges and constant pressures within the element. Although the RT0 element posesmore » many advantages, it has only been shown viable for triangular or tetrahedral elements (quadrilateral variants of this method do not pass the patch test). In the context of heterogenous materials, both of these methods have been used to model the mixed form of the Darcy equation. This work aims, in a comparative fashion, to evaluate the strengths and weaknesses of either approach for modeling Darcy flow for problems with highly varying material permeabilities and predominantly open flow boundary conditions. Such problems include carbon sequestration and enhanced oil recovery simulations for which the far-field boundary is typically described with some type of pressure boundary condition. We intend to show the degree to which the VMS formulation violates local mass conservation for these types of problems and compare the performance of the VMS and RT0 methods at boundaries between disparate permeabilities.« less

Distribution of eigenfrequencies for oscillations of the ground state in the Thomas-Fermi limit

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kevrekidis, P. G.; Pelinovsky, D. E.

In this work, we present a systematic derivation of the distribution of eigenfrequencies for oscillations of the ground state of a repulsive Bose-Einstein condensate in the semi-classical (Thomas-Fermi) limit. Our calculations are performed in one, two, and three-dimensional settings. Connections with the earlier work of Stringari, with numerical computations, and with theoretical expectations for invariant frequencies based on symmetry principles are also given.

2007-01-01

This Web site contains Lidar-derived topography (first return and bare earth) maps and GIS files for Thomas Stone National Historic Site in Maryland. These Lidar-derived topography maps were produced as a collaborative effort between the U.S. Geological Survey (USGS) Coastal and Marine Geology Program, FISC St. Petersburg, the National Park Service (NPS) South Florida/Caribbean Network Inventory and Monitoring Program, and the National Aeronautics and Space Administration (NASA) Wallops Flight Facility. One objective of this research is to create techniques to survey coral reefs and barrier islands for the purposes of geomorphic change studies, habitat mapping, ecological monitoring, change detection, and event assessment. As part of this project, data from an innovative instrument under development at the NASA Wallops Flight Facility, the NASA Experimental Airborne Advanced Research Lidar (EAARL) are being used. This sensor has the potential to make significant contributions in this realm for measuring subaerial and submarine topography wthin cross-environment surveys. High spectral resolution, water-column correction, and low costs were found to be key factors in providing accurate and affordable imagery to costal resource managers.

Tertiary volcanic rocks and uranium in the Thomas Range and northern Drum Mountains, Juab County, Utah

USGS Publications Warehouse

Lindsey, David A.

1982-01-01

The Thomas Range and northern Drum Mountains have a history of volcanism, faulting, and mineralization that began about 42 m.y. (million years) ago. Volcanic activity and mineralization in the area can be divided into three stages according to the time-related occurrence of rock types, trace-element associations, and chemical composition of mineral deposits. Compositions of volcanic rocks changed abruptly from rhyodacite-quartz latite (42-39 m.y. ago) to rhyolite (38-32 m.y. ago) to alkali rhyolite (21 and 6-7 m.y. ago); these stages correspond to periods of chalcophile and siderophile metal mineralization, no mineralization(?), and lithophile metal mineralization, respectively. Angular unconformities record episodes of cauldron collapse and block faulting between the stages of volcanic activity and mineralization. The youngest angular unconformity formed between 21 and 7 m.y. ago during basin-and-range faulting. Early rhyodacite-quartz latite volcanism from composite volcanoes and fissures produced flows, breccias, and ash-flow tuff of the Drum Mountains Rhyodacite and Mt. Laird Tuff. Eruption of the Mt. Laird Tuff about 39 m.y. ago from an area north of Joy townsite was accompanied by collapse of the Thomas caldera. Part of the roof of the magma chamber did not collapse, or the magma was resurgent, as is indicated by porphyry dikes and plugs in the Drum Mountains. Chalcophile and siderophile metal mineralization, resulting in deposits of copper, gold, and manganese, accompanied early volcanism. Te middle stage of volcanic activity was characterized by explosive eruption of rhyolitic ash-flow tuffs and collapse of the Dugway Valley cauldron. Eruption of the Joy Tuff 38 m.y. ago was accompanied by subsidence of this cauldron and was followed by collapse and sliding of Paleozoic rocks from the west wall of the cauldron. Landslides in The Dell were covered by the Dell Tuff, erupted 32 m.y. ago from an unknown source to the east. An ash flow of the Needles Range

Maxwell-Wagner Effect Applied to Microwave-Induced Self-Ignition: A Novel Approach for Carbon-Based Materials.

2018-04-03

A new method for analytical applications based on the Maxwell-Wagner effect is proposed. Considering the interaction of carbonaceous materials with an electromagnetic field in the microwave frequency range, a very fast heating is observed due to interfacial polarization that results in localized microplasma formation. Such effect was evaluated in this work using a monomode microwave system, and temperature was recorded using an infrared camera. For analytical applications, a closed reactor under oxygen pressure was evaluated. The combination of high temperature and oxidant atmosphere resulted in a very effective self-ignition reaction of sample, allowing its use as sample preparation procedure for further elemental analysis. After optimization, a high sample mass (up to 600 mg of coal and graphite) was efficiently digested using only 4 mol L -1 HNO 3 as absorbing solution. Several elements (Ba, Ca, Fe, K, Li, Mg, Na, and Zn) were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). Accuracy was evaluated by using a certified reference material (NIST 1632b). Blanks were negligible, and only a diluted solution was required for analytes absorption preventing residue generation and making the proposed method in agreement with green chemistry recommendations. The feasibility of the proposed method for hard-to-digest materials, the minimization of reagent consumption, and the possibility of multi elemental analysis with lower blanks and better limits of detection can be considered as the main advantages of this method.

Double-wells and double-layers in dusty Fermi-Dirac plasmas: Comparison with the semiclassical Thomas-Fermi counterpart

DOE Office of Scientific and Technical Information (OSTI.GOV)

Akbari-Moghanjoughi, M.

Based on the quantum hydrodynamics (QHD) model, a new relationship between the electrostatic-potential and the electron-density in the ultradense plasma is derived. Propagation of arbitrary amplitude nonlinear ion waves is, then, investigated in a completely degenerate dense dusty electron-ion plasma, using this new energy relation for the relativistic electrons, in the ground of quantum hydrodynamics model and the results are compared to the case of semiclassical Thomas-Fermi dusty plasma. Based on the standard pseudopotential approach, it is remarked that the Fermi-Dirac plasma, in contrast to the Thomas-Fermi counterpart, accommodates a wide variety of nonlinear excitations such as positive/negative-potential ion solitarymore » and periodic waves, double-layers, and double-wells. It is also remarked that the relativistic degeneracy parameter which relates to the mass-density of plasma has significant effects on the allowed matching-speed range in Fermi-Dirac dusty plasmas.« less

In this article we have solved a hypothetical problem related to the stability and gross properties of two-dimensional self-gravitating stellar objects using the Thomas-Fermi model. The formalism presented here is an extension of the standard three-dimensional problem discussed in the book on statistical physics, Part I by Landau and Lifshitz. Further, the formalism presented in this article may be considered a class problem for post-graduate-level students of physics or may be assigned as a part of their dissertation project.

The Legacy of Thomas Hodgkin Is Still Relevant 150 Years After His Death. Nothing of Humanity Was Foreign to Him.

Current leading figures in medical science usually focus on very specific topics and use cutting-edge technologies to broaden our knowledge in the field. The working environment of the nineteenth century was very different. Medical giants of that time such as Rudolph Virchow and Thomas Hodgkin had a wide-ranging scope of research and humanitarian interests and made enormous contributions to a variety of core areas of medicine and the well-being of mankind. The year 2016 marked the 150th anniversary of the death of Dr Thomas Hodgkin. Even a brief review of his life and work proves the current relevance of the outstanding deeds of this exceptional physician, medical educator, and defender of human rights for the poor and underprivileged; his vision was far ahead of his time.

PubMed

Rosenfeld, L

2000-04-01

Thomas Hodgkin's discovery of a lymph gland disorder is merely one event in a life of unusually varied public activities in the social reform and humanitarian movements of the mid-19th century. He wrote pamphlets on medical care for the working-class poor, public health, housing, sanitation, and the relief of cold, hunger, and unemployment. Hodgkin wrote about the problems arising from urban renewal and suburban development. His contributions to geographic explorations, anthropology, ethnology, and foreign affairs are virtually unknown today. Hodgkin's opposition to slavery and the slave trade involved him in the development of settlements in Africa for freed slaves and disputes with the abolitionists in America. He fought for social justice and human rights for native populations being oppressed by British foreign policy in South Africa and New Zealand. His criticism of the exploitation of Indians by the Hudson's Bay Company's fur trade contributed to a professional conflict in the highly politicized environment of Guy's Hospital and blocked advancement of his medical career. Closer to home he advocated reform of medical education and practice and sponsored adult education programs. As a member of its Senate, he helped in establishing London University, the first nonsectarian institution of higher learning in England. He lectured to working people on the means of preserving and promoting health and advocated prepaid medical care for the working poor. Concerned about unequal distribution of medical care, he opposed medical contracts to the lowest bidder and price-determined government plans for health care. He consistently maintained that the basic problems of the poor were not medical but socioeconomic. Since charity leaves nothing behind in exchange, Hodgkin was certain that greater benefits would result if charitable money was used to provide jobs. He denounced the evils of tobacco, practices of trade unions, and barbarous prize fights. On a trip to Jerusalem

This issue marks the end of an era for The Astrophysical Journal and for astronomical publishing. Helmut Abt is retiring as Editor-in-Chief after serving for 28 years, a period that saw enormous growth in the Journal and its transformation to the forefront of electronic scientific publishing. In February the ApJ office celebrated the receipt of manuscript number 40,000 under Helmut's tenure, a milestone that testifies to his impact on all of our careers. Although the names at the top of the masthead are changing, the rest of the ApJ team remains nearly unchanged, so the editorial transition should be barely noticeable. Much of the editorial work of the Journal will continue to be performed by our capable staff of Scientific Editors. I am also very fortunate to inherit Helmut's outstanding support staff in Tucson, ably headed by Janice Sexton. Our publications staff in Chicago, led by Julie Steffen, and our electronic publications staff, led by Evan Owens, are unmatched in their dedication and energy, and I have already begun working with them on further improvements to the Journal. And Helmut Abt will continue to serve the Journal over the coming months, overseeing the manuscripts that are still under review and editing the special centennial issue that will appear at the end of this year. In the coming months we will introduce several new features, most of them initiated under Helmut Abt's leadership. These will include an upgraded ApJ homepage, web tools for authors and referees, updated documentation and author instructions, and an attractive new version of the on-line journal itself. Over the longer term we are developing plans for streamlining the publication timescale and for expanding our capabilities for publishing and archiving electronic data. However my overriding priority, always, will be to uphold the Journal's reputation for scientific accuracy, impact, and integrity. I close with a personal note of thanks to Helmut Abt for his patient tutoring over

Electron and Nucleon Localization Functions of Oganesson: Approaching the Thomas-Fermi Limit

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jerabek, Paul; Schuetrumpf, Bastian; Schwerdtfeger, Peter

Fermion localization functions are used to discuss electronic and nucleonic shell structure effects in the superheavy element oganesson, the heaviest element discovered to date. Spin-orbit splitting in the 7p electronic shell becomes so large (~10 eV) that Og is expected to show uniform-gas-like behavior in the valence region with a rather large dipole polarizability compared to the lighter rare gas elements. The nucleon localization in Og is also predicted to undergo a transition to the Thomas-Fermi gas behavior in the valence region. Finally, this effect, particularly strong for neutrons, is due to the high density of single-particle orbitals.

Thomas and Baker (2012) have provided a balanced and critical review of the scientific evidence claiming that training interventions have the capacity to alter the structural morphology of the brain. Here I provide some additional considerations when reading and interpreting both the review and the original empirical articles. Research proposing to examine the capacity for structural brain plasticity needs to contemplate methodological issues and factors that could moderate or mask potentially interesting effects. Overall, although this area of research is in need of circumspection, it also could have transformative implications if structural brain plasticity in humans is possible.

Evolution and Education: Lessons from Thomas Huxley

NASA Astrophysics Data System (ADS)

Lyons, Sherrie Lynne

2010-05-01

Thomas Huxley more than anyone else was responsible for disseminating Darwin’s theory in the western world and maintained that investigating the history of life should be regarded as a purely scientific question free of theological speculation. The content and rhetorical strategy of Huxley’s defense of evolution is analyzed. Huxley argued that the classification of humans should be determined independent of any theories of origination of species. Besides providing evidence that demonstrated the close relationship between apes and humans, he also argued that a pithecoid ancestry in no way degraded humankind. In his broader defense of evolution he drew on his agnosticism to define what science could and could not explain. Theology made empirical claims and needed to be subject to the same standards of evidence as scientific claims. He maintained that even most scientific objections to evolution were religiously based. The objections to the theory fundamentally remain the same as in the nineteenth century and much can be learned from Huxley to develop effective strategies for educating the public about evolution. Huxley’s own scientific articles as well as his popular writings provide numerous examples that could be harnessed not only for the teaching of evolution, but also for understanding science as a process.

STS070-329-022 (13-22 JULY 1995)--- Astronaut Donald A. Thomas, mission specialist, prepares to activate the Microcapsules in Space (MIS-B) experiment on the space shuttle Discovery?s middeck. MIS-B is an Army project to improve the understanding of microencapsulated drug technology and demonstrate the feasibility of producing pharmaceutical microcapsules in the weightlessness of space. This is the second flight of the experiment, which originally flew on STS-53 in 1992. Microcapsules are tiny spheres about 50 to 100 micrometers in diameter (about the thickness of a strand of human hair). They are used to develop high-performance chemical products and innovative pharmaceuticals such as time-release prescriptions. The drug used in the MIS experiments was ampicillin.

Thomas-Fermi model electron density with correct boundary conditions: Application to atoms and ions

DOE Office of Scientific and Technical Information (OSTI.GOV)

Patil, S.H.

1999-01-01

The author proposes an electron density in atoms and ions, which has the Thomas-Fermi-Dirac form in the intermediate region of r, satisfies the Kato condition for small r, and has the correct asymptotic behavior at large values of r, where r is the distance from the nucleus. He also analyzes the perturbation in the density produced by multipolar fields. He uses these densities in the Poisson equation to deduce average values of r{sup m}, multipolar polarizabilities, and dispersion coefficients of atoms and ions. The predictions are in good agreement with experimental and other theoretical values, generally within about 20%. Hemore » tabulates here the coefficient A in the asymptotic density; radial expectation values (r{sup m}) for m = 2, 4, 6; multipolar polarizabilities {alpha}{sub 1}, {alpha}{sub 2}, {alpha}{sub 3}; expectation values {l_angle}r{sup 0}{r_angle} and {l_angle}r{sup 2}{r_angle} of the asymptotic electron density; and the van der Waals coefficient C{sub 6} for atoms and ions with 2 {le} Z {le} 92. Many of the results, particularly the multipolar polarizabilities and the higher order dispersion coefficients, are the only ones available in the literature. The variation of these properties also provides interesting insight into the shell structure of atoms and ions. Overall, the Thomas-Fermi-Dirac model with the correct boundary conditions provides a good global description of atoms and ions.« less

Thomas Paytherus was born in Fownhope and apprenticed in Gloucester. He practised there and in Ross-on-Wye where he and Edward Jenner undertook an autopsy on a patient with angina that they linked causally to coronary artery ossification. In 1794 Paytherus moved to London and opened a highly successful pharmacy that he later sold to his partners Savory and Moore. Paytherus was among those who advised Jenner on the publication of his work on vaccination. Then he acted as an intermediary in the dispute between Jenner and Ingen-Housz and also alerted Jenner to Pearson's claims as a pioneer of vaccination. In 1800 he published a detailed analysis of the dispute between Jenner and Woodville whose patients had developed variola-like lesions following vaccination. Their correspondence shows that Paytherus, Jenner and their families remained firm friends. Paytherus and his family moved to Abergavenny where he died in 1828.

The workshop will review recent results and discuss new directions for nuclear and hadron physics, focusing on topics to which Tony has made significant contributions, such as pion-nucleon scattering, deep inelastic scattering, chiral extrapolations, quark models of the nucleon, and lattice QCD.

The many encounters of Thomas Kuhn and French epistemology.

Simons, Massimiliano

The work of Thomas Kuhn has been very influential in Anglo-American philosophy of science and it is claimed that it has initiated the historical turn. Although this might be the case for English speaking countries, in France an historical approach has always been the rule. This article aims to investigate the similarities and differences between Kuhn and French philosophy of science or 'French epistemology'. The first part will argue that he is influenced by French epistemologists, but by lesser known authors than often thought. The second part focuses on the reactions of French epistemologists on Kuhn's work, which were often very critical. It is argued that behind some superficial similarities there are deep disagreements between Kuhn and French epistemology. This is finally shown by a brief comparison with the reaction of more recent French philosophers of science, who distance themselves from French epistemology and are more positive about Kuhn. Based on these diverse appreciations of Kuhn, a typology of the different positions within the philosophy of science is suggested. Copyright © 2017 Elsevier Ltd. All rights reserved.

On the history of the quantum. Introduction to the HQ2 special issue

NASA Astrophysics Data System (ADS)

van Dongen, Jeroen; Dieks, Dennis; Uffink, Jos; Kox, A. J.

The historiography of quantum theory exhibits a period of intense activity that started in the 1960s, with the Archives for the History of Quantum Physics project, and continued with the work of scholars like Max Jammer, Martin J. Klein, John Heilbron, Paul Forman and Thomas Kuhn. At the end of the 1970s, however, interest of historians seems to have shifted away, even if there have been notable exceptions, such as the multi-volume work by Jagdish Mehra and Helmut Rechenberg, and monographs like those of Olivier Darrigol and Mara Beller. Perhaps this development has had to do with a diminishing number of scholars possessing the necessary technical skills in physics together with historical sensitivity. Moreover, many historians of physics in this period have focused their interest on another subject, namely the development of the theory of relativity. Stimulated by the start of the Einstein Papers Project, and initiated by pioneers such as John Stachel and John Norton around 1980, very soon a dedicated group of scholars devoted time and energy to analyzing the genesis and development of general relativity, and other aspects of Einstein's science.

Integration versus apartheid in post-Roman Britain: a response to Thomas et Al. (2008).

PubMed

Pattison, John E

2011-12-01

The genetic surveys of the population of Britain conducted by Weale et al. and Capelli et al. produced estimates of the Germani immigration into Britain during the early Anglo-Saxon period, c.430-c.730. These estimates are considerably higher than the estimates of archaeologists. A possible explanation suggests that an apartheid-like social system existed in the early Anglo-Saxon kingdoms resulting in the Germani breeding more quickly than the Britons. Thomas et al. attempted to model this suggestion and showed that it was a possible explanation if all Anglo-Saxon kingdoms had such a system for up to 400 years. I noted that their explanation ignored the probability that Germani have been arriving in Britain for at least the past three millennia, including Belgae and Roman soldiers, and not only during the early Anglo-Saxon period. I produced a population model for Britain taking into account this long term, low level migration that showed that the estimates could be reconciled without the need for introducing an apartheid-like system. In turn, Thomas et al. responded, criticizing my model and arguments, which they considered persuasively written but wanting in terms of methodology, data sources, underlying assumptions, and application. Here, I respond in detail to those criticisms and argue that it is still unnecessary to introduce an apartheid-like system in order to reconcile the different estimates of Germani arrivals. A point of confusion is that geneticists are interested in ancestry, while archaeologists are interested in ethnicity: it is the bones, not the burial rites, which are important in the present context.

Whistles, bells, and cogs in machines: Thomas Huxley and epiphenomenalism.

PubMed

Greenwood, John

2010-01-01

In this paper I try to shed some historical light upon the doctrine of epiphenomenalism, by focusing on the version of epiphenomenalism championed by Thomas Huxley, which is often treated as a classic statement of the doctrine. I argue that it is doubtful if Huxley held any form of metaphysical epiphenomenalism, and that he held a more limited form of empirical epiphenomenalism with respect to consciousness but not with respect to mentality per se. Contrary to what is conventionally supposed, Huxley's empirical epiphenomenalism with respect to consciousness was not simply based upon the demonstration of the neurophysiological basis of conscious mentality, or derived from the extension of mechanistic and reflexive principles of explanation to encompass all forms of animal and human behavior, but was based upon the demonstration of purposive and coordinated animal and human behavior in the absence of consciousness. Given Huxley's own treatment of mentality, his characterization of animals and humans as "conscious automata" was not well chosen.

Extended Thomas-Fermi density functional for the unitary Fermi gas

Salasnich, Luca; Toigo, Flavio

2008-11-01

We determine the energy density ξ(3/5)nɛF and the gradient correction λℏ2(∇n)2/(8mn) of the extended Thomas-Fermi (ETF) density functional, where n is the number density and ɛF is the Fermi energy, for a trapped two-component Fermi gas with infinite scattering length (unitary Fermi gas) on the basis of recent diffusion Monte Carlo (DMC) calculations [Phys. Rev. Lett. 99, 233201 (2007)]. In particular we find that ξ=0.455 and λ=0.13 give the best fit of the DMC data with an even number N of particles. We also study the odd-even splitting γN1/9ℏω of the ground-state energy for the unitary gas in a harmonic trap of frequency ω determining the constant γ . Finally we investigate the effect of the gradient term in the time-dependent ETF model by introducing generalized Galilei-invariant hydrodynamics equations.

Mirror asymmetry for B(GT) of {sup 24}Si induced by Thomas-Ehrman shift

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ichikawa, Y.; Kubo, T.; Aoi, N.

We carried out the beta-decay spectroscopy on {sup 24}Si in order to investigate a change in configuration in the wave function induced by Thomas-Ehrman shift from a perspective of mirror asymmetry of B(GT). We observed two beta transitions to low-lying bound states in {sup 24}Al for the first time. In this proceeding, the B(GT) of {sup 24}Si is compared with that of the mirror nucleus {sup 24}Ne, and the mirror asymmetry of B(GT) is determined. Then the origin of the B(GT) asymmetry is discussed through the comparison with theoretical calculations.

Density functional of a two-dimensional gas of dipolar atoms: Thomas-Fermi-Dirac treatment

DOE Office of Scientific and Technical Information (OSTI.GOV)

Fang, Bess; Englert, Berthold-Georg

We derive the density functional for the ground-state energy of a two-dimensional, spin-polarized gas of neutral fermionic atoms with magnetic-dipole interaction, in the Thomas-Fermi-Dirac approximation. For many atoms in a harmonic trap, we give analytical solutions for the single-particle spatial density and the ground-state energy, in dependence on the interaction strength, and we discuss the weak-interaction limit that is relevant for experiments. We then lift the restriction of full spin polarization and account for a time-independent inhomogeneous external magnetic field. The field strength necessary to ensure full spin polarization is derived.

Perish, then publish: Thomas Harriot and the sine law of refraction.

Fishman, R S

2000-03-01

A talented young scientist, Thomas Harriot, wrote the first English account of the New World, "A Briefe and True Report of the New Found Land of Virginia," distinguished by its serious effort to describe and understand the American Indian. Harriot went on to make innovations in mathematics and was one of the first astronomers to use the telescope. His largely unappreciated contribution to the history of ophthalmology was the first formulation of the sine law of refraction of light, found in his unpublished papers long after his death in 1621. Willebrord Snell discovered the sine law in Holland in 1621 but also died without formally publishing it. Rene Descartes first published the sine law in 1637. The sine law of refraction became not only the prime law of all lens systems but ushered in a new world of physical laws.

The value of the Thomas-plot in the diagnostic work up of anemic patients referred by general practitioners.

In patients with inflammatory conditions, diagnosing classic iron deficiency or anemia of chronic disease is challenging. In this study, we assessed the diagnostic value of the so-called Thomas'-plot [soluble transferrin receptor (sTfR)/log ferritin (sTfr/log Ferr) and the reticulocyte hemoglobin equivalent (Ret-HE)] in the anemia work up of patients referred by general practitioners. During July 2008-March 2009, 337 consecutive patients were included because of lowered Hb values. The laboratory results of the first 133 consecutive patients were used to determine the cut-off values for the diagnostic plot. The laboratory results of these patients were assessed and interpreted independently by two investigators, blinded from sTfR/log Ferr and Ret-HE values. The following 204 patients were used to test the plot in practice. In 32% of the first 133 patients, no indication of the cause of anemia could be found. However, when using the diagnostic plot in the following 204 patients, this fraction decreased to 14%. The 'Thomas'-plot is of diagnostic value for distinguishing functional iron deficiency from classic iron deficiency in a patient population referred by general practitioners. © 2010 Blackwell Publishing Ltd.

Very little information exists relevant to the species grouping and phylogenetic relationships of the opossum genus Monodelphis Burnett. Of the clearly distinct named species, the least information is available for M. unistriata (Wagner), one of the world's most poorly known species of mammals. Extant specimens consist of the Brazilian holotype of a skin now without a skull and dating from almost 200 years ago, and a second specimen with skin and incomplete skull dating from over a hundred years ago and from Argentina. The most recent published notes on the holotype date from well over half a century ago and, all told, such notes, the earliest dating from 1842, add up to a highly fragmentary and contradictory picture. No observations whatsoever have ever been published for the second and more complete specimen. Also, no hypotheses have ever been made concerning the intrageneric affinities of M. unistriata and such affinities have also been obscure throughout the genus. Herein, we provide a detailed redescription of M. unistriata, the first published images of specimens, and the first account, beyond the previous few most vague and incomplete remarks, of the morphology of the skull. In an effort to ascertain the phylogenetic affinities of M. unistriata, we performed a combined molecular (cytochrome b) and nonmolecular (postcranial, cranial, integument, and karyotypic characters) parsimony analysis incorporating 27 species of didelphids, including 11 of Monodelphis. Our results strongly support the monophyly of Monodelphis, and place M. unistriata as sister group to M. iheringi, among the included species.

Poole Wilson, Tiffany; Davis, Kermit G

2016-08-01

The aim of this study was to assess the contributions of Thomas Waters's work in the field of health care ergonomics and beyond. Waters's research of safe patient handling with a focus on reducing musculoskeletal disorders (MSDs) in health care workers contributed to current studies and prevention strategies. He worked with several groups to share his research and assist in developing safe patient handling guidelines and curriculum for nursing students and health care workers. The citations of articles that were published by Waters in health care ergonomics were evaluated for quality and themes of conclusions. Quality was assessed using the Mixed Methods Appraisal Tool and centrality to original research rating. Themes were documented by the type of population the citing articles were investigating. In total, 266 articles that referenced the top seven cited articles were evaluated. More than 95% of them were rated either medium or high quality. The important themes of these citing articles were as follows: (a) Safe patient handling is effective in reducing MSDs in health care workers. (b) Shift work has negative impact on nurses. (c) There is no safe way to manually lift a patient. (d) Nurse curriculums should contain safe patient handling. The research of Waters has contributed significantly to the health care ergonomics and beyond. His work, in combination with other pioneers in the field, has generated multiple initiatives, such as a standard safe patient-handling curriculum and safe patient-handling programs. © 2016, Human Factors and Ergonomics Society.

Nietzche's echo--a dialogue with Thomas Altizer.

PubMed

Moss, David M

2010-03-01

Prophets provoke psychological unrest, especially when exposing accepted beliefs as profound deceptions. The biblical prophets exemplify such confrontation as do certain atheists ardently opposed to the images of God created by those seers. The German philosopher Friedrich Nietzsche dramatically illustrates this type of counterforce to the Judeo-Christian tradition. His prophet Zarathustra is intended to be a model for the modern mind, one free of superstitions inflicted by antiquated religious dogma. Nietzsche's credo "God is dead" served as a declaration for the nineteenth century. In the twentieth century, it became a theological diagnosis. As a "movement," or "tenor," the death of God or radical theology was spearheaded by Thomas Altizer, a well-published young professor center-staged during the turbulent 1960s. His work foreshadows a new strain of atheism currently represented by biologist Richard Dawkins (2006, The God delusion. New York: Houghton Mifflin), philosopher Daniel Dennett (2006, Breaking the spell. New York: Penquin), neuroscientist Sam Harris (2004, The end of faith. New York: W.W. Norton; 2008, Letter to a Christian nation. New York: Vintage), journalist Christopher Hitchens (2007, God is not great. New York: Twelve), and mathematician John Allen Paulos (Paulos 2008, Irreligion. New York: Hill & Wang). This twenty-first century crusade against belief in God is best understood as a psychodynamic ignited by Altizer's Christian atheism. The present dialogue reflects that dynamic while the prologue and epilogue reveal evidence of Providence amidst claims of God's demise in contemporary history.

The Thomas fire, west of Los Angeles, continues to advance to the west and north and is threatening a number of coastal communities, including Santa Barbara. It is now the fifth largest wildfire in modern California history. According to CAL FIRE, as of midday Dec. 11, the fire had consumed more than 230,000 acres and was 15 percent contained. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra satellite captured this image on Dec. 10. The image depicts vegetation in red, smoke in light brown, burned areas in dark grey, and active fires in yellow, as detected by the thermal infrared bands. The image covers an area of 14.3 by 19.6 miles (23 by 31.5 kilometers), and is located at 34.5 degrees north, 119.4 degrees west. https://photojournal.jpl.nasa.gov/catalog/PIA22122

Thomas Kuhn's impact on science education: What lessons can be learned?

NASA Astrophysics Data System (ADS)

Matthews, Michael R.

2004-01-01

Thomas Kuhn has had an impact in all academic fields. In science education, Kuhnian themes are especially noticeable in conceptual change research, constructivist theorizing, and multicultural education debates. Unfortunately the influence is frequently compromised by researchers having a limited understanding of Kuhn's original ideas, little exposure to the tradition of philosophical opposition to Kuhn's theories, and minimal appreciation of how Kuhn progressively qualified his initial irrationalist'' views of scientific development. One lesson to be learnt is that the science education community should more seriously and effectively engage with on-going debates and analysis in the history and philosophy of science. This is the same lesson that was learnt from the science education community's wholesale embrace of logical empiricism during the 1950s and 1960s. Another lesson is that there are powerful disciplinary, institutional, and subcultural barriers that mitigate against science educators seriously engaging with historical and philosophical scholarship.

1993-08-01

American students and other adults aged 19-75 completed a questionnaire about flashbulb memories and recollections of autobiographical events elicited by the Senate hearings for confirmation of Clarence Thomas as a Supreme Court Justice. The respondents were less likely to recall vivid image memories than were respondents in earlier studies about memories of the assassinations of John Kennedy, Robert Kennedy, and Martin Luther King. Women were significantly more likely than men to report vivid image memories and recall of autobiographical events elicited by the hearings, but they did not differ significantly from men in the ratings of these memories. Women were also significantly more likely than men to report specific memories of having been victims of sexual harassment and abuse. Women recalled reconsidering incidents in which they might have been victims of sexual harassment more often than men did. Exposure to media coverage did not differ by gender, although the amount of coverage paid attention to did correlate with the number of personal memories elicited.

Thomas C. McMurtry in November 1982. He graduated in June 1957 from the University of Notre Dame with a Bachelor of Science degree in Mechanical Engineering. McMurtry had been part of the university's Navy ROTC program, and after graduation he joined the Navy as a pilot. Before retiring from the Navy in 1964 as a Lieutenant, he graduated from the U.S. Navy Test Pilot School, and had flown such aircraft as the F9F, A3D, A4D, F3D, F-8, A-6, and S-2. McMurtry was then a consultant for the Lockheed Corporation until joining NASA as a research pilot in 1967. While at the Dryden Flight Research Center, he was co-project pilot on the F-8 Digital Fly-By-Wire program, and the 747 Shuttle Carrier Aircraft, as well as project pilot on the F-15 Digital Electronic Engine Control (DEEC) project, the KC-135 Winglets, the F-8 Supercritical Wing project, and the AD-1 Oblique Wing Project. He also made research flights in NASA's YF-12C aircraft (actually a modified SR-71). McMurtry made the last glide flight of the X-24B lifting body on November 26, 1975, and was co-pilot of the 747 Shuttle Carrier Aircraft on the first free flight of the space shuttle Enterprise on August 12, 1977. He was involved in several remotely piloted research vehicle programs, including the FAA/NASA 720 Controlled Impact Demonstration and the 3/8 F-15 Spin Research Vehicle. During McMurtry's 32 years as a pilot and manager at Dryden, he received numerous awards. These include the NASA Exceptional Service Award for his work on the F-8 Supercritical Wing, and the Iven C. Kincheloe Award from the Society of Experimental Test Pilots for his role as chief pilot on the AD-1 project, the NASA Distinguished Service Medal, and the 1999 Milton O. Thomson Lifetime Achievement Award. McMurtry also held a number of management positions at Dryden, including Chief Pilot, Director of Flight Operations, Associate Director of Flight Operations, and was the acting Chief Engineer at the time of his retirement on June 3, 1999

Sir Thomas Spencer Wells (1818-97) is best remembered both as a gynaecological surgeon, who introduced ovariectomy, and as the one who introduced the surgical forceps named after him. Far less is known of his career in the Royal Navy (RN) as an assistant surgeon and then a surgeon, and his contributions to naval medicine. Wells enlisted for the RN at the age of 23 years and for most of his naval career (1841-56) he served at the Naval Hospital, Malta (1841-48). However, from 1851 to 1853 he was surgeon and sanitary officer on the sloop, HMS Modeste. Most of Wells' contributions to the health of sailors were of a preventive nature, especially involving ventilation, in RN ships. He was also an enthusiast for quarantine and vaccination.

When Japan invaded the Philippines, two missionary dentists (Dr. McAnlis and Dr. Boots) who were forced to leave Korea were captured and interned in the Santo Thomas camp in Manila. Japan continued to bombard and plunder the Philippines in the wake of the Pacific War following the Great East Asia policy, leading to serious inflation and material deficiency. More than 4,000 Allied citizens held in Santo Thomas camp without basic food and shelter. Santo Thomas Camp was equipped with the systems of the Japanese military medical officers and Western doctors of captivity based on the Geneva Conventions(1929). However, it was an unsanitary environment in a dense space, so it could not prevent endemic diseases such as dysentery and dengue fever. With the expansion of the war in Japan, prisoners in the Shanghai and Philippine prisons were not provided with medicines, cures and food for healing diseases. In May 1944, the Japanese military ordered the prisoners to reduce their ration. The war starting in September 1944, internees received 1000 kcal of food per day, and since January 1945, they received less than 800 kcal of food. This was the lowest level of food rationing in Japan's civilian prison camps. They suffered beriberi from malnutrition, and other endemic diseases. An averaged 24 kg was lost by adult men due to food shortages, and 10 percent of the 390 deaths were directly attributable to starvation. The doctors demanded food increases. The Japanese Military forced the prisoner to worship the emperor and doctors not to record malnourishment as the cause of death. During the period, the prisoners suffered from psychosomatic symptoms such as headache, diarrhea, acute inflammation, excessive smoking, and alcoholism also occurred. Thus, the San Thomas camp had many difficulties in terms of nutrition, hygiene and medical care. The Japanese military had unethical and careless medical practices in the absence of medicines.

A total of 106 patients entered an evidence-based limb salvage protocol (LSP) for Wagner Grade 3 or 4 (WG3/4) DFU and intention-to-treat adjunctive hyperbaric oxygen (HBO₂) therapy. A second cohort of 53 patients had a primary lower extremity amputation (LEA), either below the knee (BKA) or above the knee (AKA) and were not part of the LSP. Ninety-six of 106 patients completed the LSP/HBO₂with an average cost of USD $33,100. Eighty-eight of 96 patients (91.7%) who completed the LSP/HBO₂had intact lower extremities at one year. Thirty-four of the 96 patients (35.4%) died during the follow-up period. Costs for a historical cohort of 53 patients having a primary major LEA range from USD $66,300 to USD $73,000. Twenty-five of the 53 patients (47.2%) died. The difference in cost of care and mortality between an LSP with adjunctive HBO₂therapy vs. primary LEA is staggering. We conclude that an aggressive limb salvage program that includes HBO₂ therapy is cost-effective.

The astronomy community lost a good friend when Tom Metcalf was killed in a skiing accident on Saturday, 7 July 2007, in the mountains near Boulder, Colorado. Tom was widely known for prolific work on solar magnetic fields, hard-X-ray imaging of solar flares, and spectral line diagnostics. He was often characterized as "one of the nicest guys in science." Born October 5, 1961 in Cheverly, Maryland, to Fred and Marilyn, Thomas R. Metcalf joined his sister, Karen, two years his elder, in a close family that loved sailing, inquisitiveness, and the natural world. Sibling rivalry (usually a Tonka truck intruding on Barbie's sub-table "castle") melted when Tom and Karen collaborated on elaborately engineered room-sized blanket-forts. Tom confidently signed up at age of three to crew for his family's sailboat; when the family moved to California in 1966, as Tom's father took a Professor of Mathematics position at the University of California Riverside, Tom's love for sailing was well-established. Week-long cruises or short trips in the harbor were all fun; when school friends came aboard, it was even better--if "only slightly too crowded" from the adults' points of view. Tom's introduction to astronomy began one cold, very clear, December night in the early 1970s, on a family camping trip to Death Valley. The "Sidewalk Astronomers of San Francisco" had lined the sidewalk near the visitors' center with all sorts of telescopes for public viewing. Soon after, Tom and his boyhood friend Jim O'Linger were building their own scopes, attending "Amateur Telescope Makers" conferences, and Tom was setting up his scope on a sidewalk for public viewing. In 1986, Tom set up his telescope on the bluffs above Dana Point Harbor, and gave numerous strangers a stunning view of Halley's Comet. His interest in physics and mathematics became evident during Tom's last years in high school (Poly High in Riverside), and as a senior he qualified to take freshman Physics at the University of

The clearance of recombinant human granulocyte-colony stimulating factor (rhG-CSF) is known to decrease with dose increase, and to be saturable. The average clearance after intravenous administration will be lower than that after subcutaneous administration. Therefore, the apparent absolute bioavailability with subcutaneous administration calculated from the AUC ratio is expected to be an underestimate. The absorption pharmacokinetics after subcutaneous administration was examined using the results of the bioequivalency study between two rhG-CSF formulations with a dose of 2 microg/kg. The analysis was performed using a modified Wagner-Nelson method with the nonlinear elimination model. The apparent absolute bioavailability for subcutaneous administration was 56.9 and 67.5% for each formulation, and the ratio between them was approximately 120%. The true absolute bioavailability was, however, estimated to be 89.8 and 96.9%, respectively, and the ratio was approximately 108%. The absorption pattern was applied to other doses, and the predicted clearance values for subcutaneous and intravenous administrations were then similar to the values for several doses reported in the literature. The underestimation of bioavailability was around 30%, and the amplification of difference was 2.5 times, from 8 to 20%, because of the nonlinear pharmacokinetics. The neutrophil increases for each formulation were identical, despite the different bioavailabilities. The reason for this is probably that the amount eliminated through the saturable process, which might indicate the amount consumed by the G-CSF receptor, was identical for each formulation.

Improved pump turbine transient behaviour prediction using a Thoma number-dependent hillchart model

NASA Astrophysics Data System (ADS)

Manderla, M.; Kiniger, K.; Koutnik, J.

2014-03-01

Water hammer phenomena are important issues for high head hydro power plants. Especially, if several reversible pump-turbines are connected to the same waterways there may be strong interactions between the hydraulic machines. The prediction and coverage of all relevant load cases is challenging and difficult using classical simulation models. On the basis of a recent pump-storage project, dynamic measurements motivate an improved modeling approach making use of the Thoma number dependency of the actual turbine behaviour. The proposed approach is validated for several transient scenarios and turns out to increase correlation between measurement and simulation results significantly. By applying a fully automated simulation procedure broad operating ranges can be covered which provides a consistent insight into critical load case scenarios. This finally allows the optimization of the closing strategy and hence the overall power plant performance.

Thomas Graham Brown undertook seminal experiments on the neural control of locomotion between 1910 and 1915. Although elected to the Royal Society in 1927, his locomotion research was largely ignored until the 1960s when it was championed and extended by the distinguished neuroscientist, Anders Lundberg. Puzzlingly, Graham Brown's published research stopped in the 1920s and he became renowned as a mountaineer. In this article, we review his life and multifaceted career, including his active neurological service in WWI. We outline events behind the scenes during his tenure at Cardiff's Institute of Physiology in Wales, UK, including an interview with his technician, Terrence J. Surman, who worked in this institute for over half a century.

2002-01-01

Two-proton decays of 12O and 16Ne ground states are studied in a three-body model. We have found that the two-proton widths for the states should be much less than the existing experimental values (about 10 times for 12O and about 100 times for 16Ne). We also have found that the structure of these states differs significantly from the mirror isobaric analog states (IAS): breaking of isobaric symmetry is at the level of tens of percents. Together with a corresponding decrease of the Coulomb energy, this effect can be considered as a three-body mechanism of the Thomas-Ehrman shift.

Calculations of nuclear electric shieldings, equivalent to dipole moment geometric derivatives, and related to atomic polar tensors, are presented for X-CH 3 and X-C 2H 5 molecules with X=NH 2, OH and F. The electric shielding tensors satisfy a constraint for the electrostatic equilibrium, i.e., the mixed length-acceleration Thomas-Reiche-Khun sum rule, which gives important indications on the reliability of theoretical predictions of IR intensities and leads to the definition of atomic populations. Numerical evidence was found for the additivity and transferability of atomic populations, within the X-substituted alkane series.

Salkind, Alvin J.; Israel, Paul

Thomas Alva Edison, the most prolific inventor in North America, with over 1000 patents, was the descendant of early settlers from the Netherlands to the Hudson Valley region of New York/New Jersey. However, his genealogical trail encompasses many cities, provinces, states, and countries, including Holland, France, Scotland, New Amsterdam, New York, New Jersey, Nova Scotia, Ontario, Ohio, and Michigan. He was motivated to develop and invent in response to perceived needs of commercial devices and was the creator of the concept of an industrial research laboratory. His activities covered a wide-range of chemical, electrical, medical, metallurgical, entertainment, and communication devices and led to the creation of major worldwide industries. However, his expressed underlying concern was the "service it might give others". This presentation reviews commercial developments in comparison with the technologies and motivations of the time and is illustrated by material from the Rutgers University 'Edison Papers Project', Edison's personal notes found in the Edison Battery Factory and preserved by Professor Salkind, and records of The Electrochemical Society.

Propagation and head-on collisions of ion-acoustic solitons in a Thomas-Fermi magnetoplasma: Relativistic degeneracy effects

DOE Office of Scientific and Technical Information (OSTI.GOV)

Akbari-Moghanjoughi, M.

Small amplitude propagation and quasielastic head-on collision of ion-acoustic solitary waves (IASWs) are investigated in a degenerate Thomas-Fermi electron-positron-ion magnetized plasma using extended Poincare-Lighthill-Kuo reductive perturbation method for both ultrarelativistic and nonrelativistic electron/positron degeneracy cases. It is observed that both bright- and dark-type solitary shapes can exist in such plasma, depending on two critical values. The shape of ion-acoustic solitary structures as well as sign of their collision phase shifts are both determined by the same critical values. It is further revealed that relativistic degeneracy of electrons/positrons has significant effect on the propagation as well as interaction of IASWs.

Relativistic Thomas-Fermi treatment of compressed atoms and compressed nuclear matter cores of stellar dimensions

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rotondo, M.; Rueda, Jorge A.; Xue, S.-S.

The Feynman-Metropolis-Teller treatment of compressed atoms is extended to the relativistic regimes. Each atomic configuration is confined by a Wigner-Seitz cell and is characterized by a positive electron Fermi energy. The nonrelativistic treatment assumes a pointlike nucleus and infinite values of the electron Fermi energy can be attained. In the relativistic treatment there exists a limiting configuration, reached when the Wigner-Seitz cell radius equals the radius of the nucleus, with a maximum value of the electron Fermi energy (E{sub e}{sup F}){sub max}, here expressed analytically in the ultrarelativistic approximation. The corrections given by the relativistic Thomas-Fermi-Dirac exchange term are alsomore » evaluated and shown to be generally small and negligible in the relativistic high-density regime. The dependence of the relativistic electron Fermi energies by compression for selected nuclei are compared and contrasted to the nonrelativistic ones and to the ones obtained in the uniform approximation. The relativistic Feynman-Metropolis-Teller approach here presented overcomes some difficulties in the Salpeter approximation generally adopted for compressed matter in physics and astrophysics. The treatment is then extrapolated to compressed nuclear matter cores of stellar dimensions with A{approx_equal}(m{sub Planck}/m{sub n}){sup 3}{approx}10{sup 57} or M{sub core}{approx}M{sub {circle_dot}}.

Sloto, Ronald A.

1997-01-01

A suite of borehole geophysical logs and heat-pulse-flowmeter measurements run in the former production well at the John Wagner and Sons, Inc. plant indicate two zones of borehole flow. In the upper part of the well, water enters the borehole through a fracture at 90 ft (feet) below floor level, moves upward, and exits the borehole through a fracture at 72 ft below floor level. Water also enters the borehole through fractures at 205-213, 235, and 357 ft below floor level; moves downward; and exits the borehole through fractures at 450-459, 468-470, and 483-490 ft below floor level. Five zones were selected for aquifer-isolation (packer) tests on the basis of borehole geophysical logs. The zones were isolated using a straddle-packer assembly. The lowermost three zones (below 248, 223 to 248, and 198 to 223 ft below floor level) were hydraulically isolated from zones above and below. Specific capacities were 0.12, 0.034, and 0.15 gallons per minute per foot, respectively. The hydrograph from zone 2 (223 to 248 ft below floor level) showed interference from a nearby pumping well. For the upper two zones (81 to 106 and 57 to 81 ft below floor level), similar drawdowns in the isolated zone and the zones above and below the isolated zone indicate that these fractures are hydraulically connected outside the borehole in the unconfined part of the Stockton Formation. The specific capacity of zones 4 and 5 are similar—0.82 and 0.61, respectively.

Garza, R; Cardona, C; Singh, S P

1996-03-01

The bean-pod weevil (BPW), Apion godmani Wagner, often causes heavy losses in crops of common bean (Phaseolus vulgaris L.). Farmers need resistant bean cultivars to minimize losses, cut production costs, stabilize seed yield, and reduce pesticide use and consequent health hazards. To design effective breeding methods, breeders need new and better sources of resistance and increased knowledge of their modes of inheritance. We therefore: (1) compared sources of resistance to BPW, (2) studied the inheritance of resistance, and (3) determined whether the sources possess similar or different genes for BPW resistance. The following sources of resistance, originating from the Mexican highlands, were evaluated for 3 years at INIFAP-Santa Lucía de Prias, Texcoco, Mexico: 'Amarillo 153', 'Amarillo 169', 'Hidalgo 58', 'J 117', 'Pinto Texcoco', 'Pinto 168', and 'Puebla 36'. All except 'Puebla 36' were crossed with the susceptible cultivar 'Jamapa'. 'Amarillo 153' and 'Puebla 36' were crossed with another susceptible cultivar, 'Bayo Mex'. The parents, F1 hybrids, and F2 populations were evaluated for BPW damage in 1992. Backcrosses of the F1 of Jamapa/Pinto 168 to the respective susceptible and resistant parents were also evaluated in 1992. All seven resistant accessions were crossed in all possible combinations, excluding reciprocals. The resulting 21 F1 hybrids and 21 F2 populations were evaluated for BPW damage in 1994. 'J 117' had the highest level of resistance to BPW. 'Pinto Texcoco' and 'Puebla 36' had the highest mean damage score of all seven sources of resistance. The F1 hybrids between susceptible parents and resistant sources were generally intermediate. Two genes segregating independently controlled the BPW resistance in each accession. One gene, Agm, has no effect when present alone, whereas the other gene, Agr, alone conferred intermediate resistance. When both genes were present, resistance to BPW was higher. Based on mean BPW damage scores, all 21 F1 hybrids

This article traces the career of Thomas Adeoye Lambo, the first European-trained psychiatrist of indigenous Nigerian (Yoruba) background and one of the key contributors to the international development of transcultural psychiatry from the 1950s to the 1980s. The focus on Lambo provides some political, cultural and geographical balance to the broader history of transcultural psychiatry by emphasizing the contributions to transcultural psychiatric knowledge that have emerged from a particular non-western context. At the same time, an examination of Lambo's legacy allows historians to see the limitations of transcultural psychiatry's influence over time. Ultimately, this article concludes that the history of transcultural psychiatry might have more to tell us about the politics of the 'transcultural' than the practice of 'psychiatry' in post-colonial contexts.

Between 1865 and 1868 the Manchester architect, Thomas Worthington and Florence Nightingale corresponded about hospital design. Worthington was involved in building hospitals for two Poor Law Unions in Manchester. The designs of both hospitals were based on the 'pavilion' principle of which Nightingale became a vocal national champion. Through five letters written by Nightingale to Worthington, the paper explores Nightingale's views focussing on her admiration for the designs, and examines the importance of these commissions for Worthington's career as a hospital architect.

In pharmacokinetics, the Wagner-Nelson (W-N) method can accurately estimate the rate of drug absorption from its urinary elimination rate. A stable isotope (13C) breath test attempts to estimate the rate of absorption of 13C, as an index of gastric emptying rate, from the rate of pulmonary elimination of 13CO2. The time-gastric emptying curve determined by the breath test is quite different from that determined by scintigraphy or ultrasonography. In this report, we have shown that the W-N method can adjust the difference. The W-N equation to estimate gastric emptying from breath data is as follows: the fractional cumulative amount of gastric contents emptied by time t = Abreath (t)/Abreath (infinity) + (1/0.65).d[Abreath (t)/Abreath (infinity) ]/dt, where Abreath (t) = the cumulative recovery of 13CO2 in breath by time t and Abreath ( infinity ) = the ultimate cumulative 13CO2 recovery. The emptying flow curve generated by ultrasonography was compared with that generated by the W-N method-adjusted breath test in 6 volunteers. The emptying curves by the W-N method were almost identical to those by ultrasound. The W-N method can generate an accurate emptying flow curve from 13CO2 data, and it can adjust the difference between ultrasonography and the breath test. Copyright 2004 S. Karger AG, Basel

Movements of fluvial Bonneville cutthroat trout in the Thomas Fork of the Bear River, Idaho-Wyoming

Colyer, W.T.; Kershner, J.L.; Hilderbrand, R.H.

2005-01-01

The majority of interior subspecies of cutthroat trout Oncorhynchus clarkii have been extirpated from large rivers by anthropogenic activities that have fragmented habitats and introduced nonnative competitors. Selective pressures against migratory behaviors and main-stem river occupation, coupled with conservation strategies that isolate genetically pure populations above barriers, have restricted gene flow and prevented expression of the fluvial life history in many populations. Existing knowledge about the movements and home range requirements of fluvial cutthroat trout is, therefore, limited. Our objectives in this study were to (1) determine the extent of seasonal home ranges and mobility of Bonneville cutthroat trout O. c. utah (BCT) in the Thomas Fork and main-stem Bear River and (2) evaluate the role of a water diversion structure functioning as a seasonal migration barrier to fish movement. We implanted 55 BCT in the Thomas Fork of the Bear River, Idaho, with radio transmitters and located them bimonthly in 1999–2000 and weekly in 2000–2001. We found fish to be more mobile than previously reported. Individuals above the diversion barrier occupied substantially larger home ranges than those below the barrier (analysis of variance: P = 0.0003; median = 2,225 m above barrier; median = 500 m below barrier) throughout our study, and they moved more frequently (mean, 0.89 movements/contact; range, 0.57–1.00) from October 2000 through March 2001 than fish below the barrier (mean, 0.45 movements/contact; range, 0.00–1.00). During the spring of both years, we located radio-tagged fish in both upstream and neighboring tributaries as far as 86 km away from our study site. Our results document the existence of a fluvial component of BCT in the Bear River and its tributaries and suggest that successful efforts at conservation of these fish must focus on main-stem habitats and the maintenance of seasonal migration corridors.

Background To study the severity of diabetic neuropathy, diabetic retinopathy and grades of diabetic foot syndrome for correlations with corneal subbasal nerve plexus (SBP) changes in Congolese patients with type 2 diabetes. Methodology/Principal Findings Twenty-eight type 2 diabetes patients with diabetes-related foot ulceration were recruited in a diabetic care unit in Kinshasa, Democratic Republic of Congo. Corneal SBP was investigated by confocal laser-scanning microscopy to analyse nerve fibre density (NFD) [µm/ µm²], number of branches [n] and number of connectivity points [n]. Foot ulceration was graded using the Wagner ulcer classification. Corneal sensitivity (Cochet-Bonnet), Neuropathy Symptom Score (NSS), Neuropathy Disability Score (NDS), ankle-brachial index (ABI) and ophthalmological status were evaluated. Foot ulceration was ranked as mild (Wagner 0-1: 13 patients/46.4%), moderate (Wagner 2-3: 10 patients/35.7%) and severe (Wagner 4-5: 5 patients/17.9%). The correlation between Wagner Score and NFD (p=0.017, r = - 0,454), NDS and NFD (p=0,039, r = - 0.400) as well as Wagner Score and HbA1c (p=0,007, r = - 0.477) was stated. Significant differences in confocal SBP parameters were observed between Wagner 0-1 and Wagner 4 5 (number of branches (p=0.012), number of connectivity points (p=0.001), nerve fibre density (p=0.033)) and ABI (p=0.030), and between Wagner 2-3 and Wagner 4-5 (number of branches (p=0.003), number of connectivity points (p=0.005) and nerve fibre density (p=0.014)).

Mermin-Wagner physics, (H ,T ) phase diagram, and candidate quantum spin-liquid phase in the spin-1/2 triangular-lattice antiferromagnet Ba8CoNb6O24

Ba8CoNb6O24 presents a system whose Co2 + ions have an effective spin 1/2 and construct a regular triangular-lattice antiferromagnet (TLAFM) with a very large interlayer spacing, ensuring purely two-dimensional character. We exploit this ideal realization to perform a detailed experimental analysis of the S =1 /2 TLAFM, which is one of the keystone models in frustrated quantum magnetism. We find strong low-energy spin fluctuations and no magnetic ordering, but a diverging correlation length down to 0.1 K, indicating a Mermin-Wagner trend toward zero-temperature order. Below 0.1 K, however, our low-field measurements show an unexpected magnetically disordered state, which is a candidate quantum spin liquid. We establish the (H ,T ) phase diagram, mapping in detail the quantum fluctuation corrections to the available theoretical analysis. These include a strong upshift in field of the maximum ordering temperature, qualitative changes to both low- and high-field phase boundaries, and an ordered regime apparently dominated by the collinear "up-up-down" state. Ba8CoNb6O24 , therefore, offers fresh input for the development of theoretical approaches to the field-induced quantum phase transitions of the S =1 /2 Heisenberg TLAFM.

Interbasin groundwater flow in south central Nevada: A further comment on the discussion between Davisson et. al.. [1999a, 1999b] and Thomas [1999

This commentary is submitted to demonstrate, first, that their dismissal of this data set is unfounded and, second, that these potentiometric data call into question the central thesis of the original paper by Davisson et al.

The Reverend Thomas Hincks FRS (1818-1899): taxonomist of Bryozoa and Hydrozoa.

Calder, Dale R

2009-10-01

Thomas Hincks was born 15 July 1818 in Exeter, England. He attended Manchester New College, York, from 1833 to 1839, and received a B.A. from the University of London in 1840. In 1839 he commenced a 30-year career as a cleric, and served with distinction at Unitarian chapels in Ireland and England. Meanwhile, he enthusiastically pursued interests in natural history. A breakdown in his health and permanent voice impairment during 1867-68 while at Mill Hill Chapel, Leeds, forced him reluctantly to resign from active ministry in 1869. He moved to Taunton and later to Clifton, and devoted much of the rest of his life to natural history. Hincks was elected a Fellow of the Royal Society of London in 1872 for noteworthy contributions to natural history. Foremost among his publications in science were "A history of the British hydroid zoophytes" (1868) and "A history of the British marine Polyzoa" (1880). Hincks named 24 families, 52 genera and 360 species and subspecies of invertebrates, mostly Bryozoa and Hydrozoa. Hincks died 25 January 1899 in Clifton, and was buried in Leeds. His important bryozoan and hydroid collections are in the Natural History Museum, London. At least six genera and 13 species of invertebrates are named in his honour.

Thomas Young's contribution to visual optics: the Bakerian Lecture "on the mechanism of the eye".

Thomas Young (1773-1829) carried out major pioneering work in many different subjects. In 1800 he gave the Bakerian Lecture of the Royal Society on the topic of the "mechanism of the eye": this was published in the following year (T. Young, 1801). Young used his own design of optometer to measure refraction and accommodation, and discovered his own astigmatism. He considered the different possible origins of accommodation and confirmed that it was due to change in shape of the lens rather than to change in shape of the cornea or an increase in axial length. However, the paper also dealt with many other aspects of visual and ophthalmic optics, such as biometric parameters, peripheral refraction, longitudinal chromatic aberration, depth-of-focus and instrument myopia. These aspects of the paper have previously received little attention. We now give detailed consideration to these and other less-familiar features of Young's work and conclude that his studies remain relevant to many of the topics which currently engage visual scientists.

Museum security and the Thomas Crown Affair.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Michaud, E. C.

Over the years, I've daydreamed about stealing a Vermeer, a Picasso, or Rembrandt. It tickles me, as much as watching the reboot of The Thomas Crown Affair. Why is it, do you suppose, so much fun to think about stealing a world renowned piece off the wall of a major metropolitan museum? Is it the romantic thoughts of getting away with it, walking past infrared detectors, and pressure sensors ala Indiana Jones with the sack of sand to remove the idol without triggering the security system? Is it the idea of snatching items with such fantastic prices, where the romancemore » of possessing an item of such value is less intoxicating than selling it to a private collector for it to never be seen again? I suspect others share my daydreams as they watch theater or hear of a brazen daylight heist at museums around the world, or from private collections. Though when reality sets in, the mind of the security professional kicks in. How could one do it, why would one do it, what should you do once it's done? The main issue a thief confronts when acquiring unique goods is how to process or fence them. They become very difficult to sell because they are one-of-a-kind, easy to identify, and could lead to the people involved with the theft. The whole issue of museum security takes up an ironic twist when one considers the secretive British street artist 'Banksy'. Banksy has made a name for himself by brazenly putting up interesting pieces of art in broad daylight (though many critics don't consider his work to be art) on building walls, rooftops, or even museums. I bring him up for a interesting take on what may become a trend in museum security. In March of 2005, Banksy snuck a piece of his called 'Vandalized Oil Painting' into the Brooklyn Museum's Great Historical Painting Wing, plus 3 other pieces into major museums in New York. Within several days, 2 paintings had been torn down, but 2 stayed up much longer. In his home country of the UK, a unauthorized piece he created and

Which Way Is Up? Thomas S. Kuhn's Analogy to Conceptual Development in Childhood

NASA Astrophysics Data System (ADS)

Levine, Alexander T.

In the Preface to his Structure Of Scientific Revolutions, Thomas S. Kuhn let it be known that his view of scientific development was indebted to the work of pioneering developmental psychologist Jean Piaget. Piaget's model of conceptual development in childhood, on which the child passes through several discontinuous stages, served as the template for Kuhn's reading of the history of a scientific discipline, on which mutually incommensurable periods of normal science are separated by scientific revolutions. The analogy to conceptual change in childhood pervades Kuhn's corpus, serving as the central motif in his well-known essays, A Function for Thought Experiments and Second Thoughts on Paradigms. But it is deeply problematic. For as a careful student of Piaget might note, Piaget, and the developmental psychologists he inspired, relied on the same analogy, but with the order of epistemic dependencies reversed. One begins to worry that Kuhn's use of the analogy, and its subsequent re-use by developmental psychologists, sneaks a vicious circularity into our understanding of important processes. This circularity is grounds for some concern on the part of science educators accustomed to employing such Kuhnian notions as incommensurability and paradigm.

The mine and the furnace: Francis Bacon, Thomas Russell, and early Stuart mining culture.

Pastorino, Cesare

2009-01-01

Notwithstanding Francis Bacon's praise for the philosophical role of the mechanical arts, historians have often downplayed Bacon's connections with actual artisans and entrepreneurs. Addressing the specific context of mining culture, this study proposes a rather different picture. The analysis of a famous mining metaphor in The Advancement of Learning shows us how Bacon's project of reform of knowledge could find an apt correspondence in civic and entrepreneurial values of his time. Also, Bacon had interesting and so far unexplored links with the early modern English mining enterprises, like the Company of Mineral and Battery Works, ofwhich he was a shareholder. Moreover, Bacon's notes in a private notebook, Commentarius Solutus, and records of patents of invention, allow us to start grasping Bacon's connections with the metallurgist and entrepreneur Thomas Russell. Lastly, this paper argues that, to fully understand Bacon's links with the world of Stuart technicians and entrepreneurs, it is necessary to consider a different and insufficiently studied aspect of Bacon's interests, namely his work as patents referee while a Commissioner of Suits.

Serum hepcidin-25 may replace the ferritin index in the Thomas plot in assessing iron status in anemic patients.

Biochemical markers of iron deficiency do not distinguish iron-deficient anemia (IDA) from the anemia of chronic disease (ACD) and the combined state of ACD/IDA. Serum hepcidin-25 might be a marker resolving this problem. We investigated the extent to which serum hepcidin-25 enables the differentiation of the states above in comparison with the ferritin index plot, the so-called Thomas plot [soluble transferrin receptor (sTfR)/log ferritin and the reticulocyte hemoglobin content (CHr)]. Serum hepcidin-25 was determined in 155 anemic patients who were classified as having latent iron deficiency (latent ID), IDA, ACD, or ACD/IDA using the ferritin index plot (Thomas plot). Hepcidin-25 was determined using an isotope-dilution micro-HPLC-tandem mass spectrometry method. The ability to discriminate among these states based on serum hepcidin-25 alone or in combination with the CHr was evaluated in a receiver operating characteristic curve analysis and a comparison with the recently established ferritin index plot. Serum hepcidin-25 correlated with ferritin and the ferritin index. Use of a hepcidin-25 cutoff level of ≤4 nmol/l allowed the differentiation of IDA from ACD and ACD/IDA. Furthermore, the discrimination of ACD/IDA from ACD required combination with CHr in a new plot (hepcidin-25 and the CHr). The hepcidin-25 plot and the ferritin index plot showed a good correspondence in the differentiation of iron states in patients with anemia. Patients with IDA can be differentiated from ACD and ACD/IDA but not ACD from ACD/IDA based on hepcidin-25 alone. The combination of hepcidin-25 with CHr in the hepcidin-25 plot was useful for the differentiation of the states above. © 2010 Blackwell Publishing Ltd.

Numerical convergence of the self-diffusion coefficient and viscosity obtained with Thomas-Fermi-Dirac molecular dynamics.

Computations of the self-diffusion coefficient and viscosity in warm dense matter are presented with an emphasis on obtaining numerical convergence and a careful evaluation of the standard deviation. The transport coefficients are computed with the Green-Kubo relation and orbital-free molecular dynamics at the Thomas-Fermi-Dirac level. The numerical parameters are varied until the Green-Kubo integral is equal to a constant in the t→+∞ limit; the transport coefficients are deduced from this constant and not by extrapolation of the Green-Kubo integral. The latter method, which gives rise to an unknown error, is tested for the computation of viscosity; it appears that it should be used with caution. In the large domain of coupling constant considered, both the self-diffusion coefficient and viscosity turn out to be well approximated by simple analytical laws using a single effective atomic number calculated in the average-atom model.

This CD-ROM is a digitally scanned suite of master 'locality' maps produced by Dr. Thomas M. Bown. The maps are archived in the US Geological Survey Field Records. The maps feature annual compilations of newly established fossil (nineteen 7.5 degree maps) of central basin data collections. This master suite of forty-four maps represents a considerably broader geographic range within the basin. Additionally, three field seasons of data were compiled into the master suite of maps after the final editing of the Professional Paper. These maps are the culmination of Dr. Bown's Bighorn Basin research as a vertebrate paleontologist for the USGS. Data include Yale, Wyoming, Duke, Michigan and USGS localities. Practical topographic features are also indicated, such as jeep=trail access, new reservoirs, rerouted roadbeds, measured sections, fossil reconnaissance evaluations (G=good, NG=no good and H=hideous), faults, palcosol stages, and occasionally 'camp' vernacular for locality names.

Catholic unionism and heterodoxy in Irish Victorian Medicine: A biography of Thomas More Madden (1838-1902).

Kennerk, Barry

2016-05-01

It is not easy to précis the life of gynaecologist and obstetrician Thomas More Madden. Aside from his prolific penmanship and championing of societal issues, a study of his life serves to demonstrate the crossroads at which orthodox medicine stood during the late nineteenth century - a period of transition between 'heroic' and modern health care. Reflecting this state of flux, Madden wrote several books about childbirth but he was also interested in heterodox subjects including heliotherapy and hydrotherapy. His political beliefs were no less eclectic. On one hand he was a Catholic 'Unionist', in favour of maintaining Ireland's place in the UK, but his writing was also imbued with the spirit of the Gaelic literary revival. Through his work he tried to make a case, not just for Ireland's place in the western health care tradition but also for its contribution to contemporary medicine. © The Author(s) 2014.

Abstract Recent molecular phylogenetic studies and reevaluation of morphological characters have led to the inclusion of Glochidion within a broader delimitation of Phyllanthus. It is necessary for preparation of the Vascular Flora of the Marquesas Islands to make new combinations for the Marquesan species. We also provide the relevant combinations and listing of all of the currently accepted species of Phyllanthus on Pacific oceanic islands for a total of 69 native species in oceanic Pacific islands. Glochidion tooviianum J. Florenceis here placed into synonymy of Phyllanthus marchionicus (F. Br.) W. L. Wagner & Lorence based on new assessment of recently collected specimens from Nuku Hiva. Glochidion excorticans Fosberg var. calvum Fosberg is placed into synonomy of Phyllanthus ponapense (Hosokawa) W. L. Wagner & Lorenceand Glochidion puberulum Hosokawa and Glochidion excorticans Fosberg are placed in synonymy of Phyllanthus senyavinianus (Glassman)W. L. Wagner & Lorence based on new study of all Micronesian specimens available to us. No infraspecific taxa are recognized within Phyllanthus pacificus of the Marquesas Islands. Species already with valid names in Phyllanthus are also listed for completeness and convenience. Brief distributional comments are given for each species. We propose new names for species for which a new combination is not possible: Phyllanthus florencei W. L. Wagner & Lorence, nom. nov., Phyllanthus mariannensis W.L. Wagner & Lorence, nom. nov., Phyllanthus otobedii W. L. Wagner & Lorence, Phyllanthus raiateaensis W. L. Wagner & Lorence, Phyllanthus st-johnii W. L. Wagner & Lorence, nom. nov., and Phyllanthus vitilevuensis W.L. Wagner & Lorence, nom. nov. We provide information for four additional naturalized species within the region (Phyllanthus amarus, Phyllanthus debilis, Phyllanthus tenellus, and Phyllanthus urinaria). The name Glochidion ramiflorum widely applied to Pacific island populations is here considered to be a species further

Thomas Willis, the Restoration and the First Works of Neurology

PubMed Central

Caron, Louis

2015-01-01

This article provides a new consideration of how Thomas Willis (1621–75) came to write the first works of ‘neurology’, which was in its time a novel use of cerebral and neural anatomy to defend philosophical claims about the mind. Willis’s neurology was shaped by the immediate political and religious contexts of the English Civil War and Restoration. Accordingly, the majority of this paper is devoted to uncovering the political necessities Willis faced during the Restoration of the English monarchy in 1660, with particular focus on the significance of Willis’s dedication of his neurology and natural philosophy to the Archbishop of Canterbury, Gilbert Sheldon. Because the Restoration of Charles II brought only a semblance of order and peace, Willis and his allies understood the need for a coherent defense of the authority of the English church and its liturgy. Of particular importance to Sheldon and Willis (and to others in Sheldon’s circle) were the specific ceremonies described in the Book of Common Prayer, a manual that directed the congregation to assume various postures during public worship. This article demonstrates that Willis’s neurology should be read as an intervention in these debates, that his neurology would have been read at the time as an attempt to ground orthodox worship in the structure of the brain and nerves. The political necessities that helped to shape Willis’s project also help us to better understand Willis’s innovative insistence that philosophical statements about the mind should be formulated only after a comprehensive anatomical investigation of the brain and nerves.

Thomas Birch's 'Weekly Letter' (1741-66): correspondence and history in the mid-eighteenth-century Royal Society.

Ellis, Markman

2014-09-20

Thomas Birch (1705-66), Secretary of the Royal Society from 1752 to 1765, and Philip Yorke, second Earl of Hardwicke (1720-90), wrote a 'Weekly Letter' from 1741 to 1766, an unpublished correspondence of 680 letters now housed in the British Library (Additional Mss 35396-400). The article examines the dimensions and purposes of this correspondence, an important conduit of information for the influential coterie of the 'Hardwicke circle' gathered around Yorke in the Royal Society. It explores the writers' self-conception of the correspondence, which was expressed in deliberately archaic categories of seventeenth-century news exchange, such as the newsletter, aviso and a-la-main. It shows how the letter writers negotiated their difference in status through the discourse of friendship, and concludes that the 'Weekly Letter' constituted for the correspondents a form of private knowledge, restricted in circulation to their discrete group, and as such unlike the open and networked model of Enlightenment science.

Notes made by Thomas Harriot on the treatises of François Viète

2008-03-01

In the Archive for History of Exact Sciences in 1979 Johannes Lohne published "A survey of Harriot's scientific writings". This has remained until now the only survey of the surviving manuscripts of Thomas Harriot (ca. 1560-1621). Lohne's paper is still a useful resource but it touches only very sketchily on Harriot's debt to François Viète (1540-1603), even though dozens of Harriot's manuscript sheets are filled with re-workings of problems or theorems from Viète's various treatises. Many of these sheets carry overt references to page or proposition numbers in Viète's publications, while others reveal themselves through inspection of the problem they contain. The primary aim of the present paper is to offer a new survey, of precisely those sheets where Harriot can be seen working on the mathematics of Viète. In doing so, it also offers an insight into the reception of Viète's work within his own lifetime at the hands of one of his most astute and able readers.

The correspondence of Thomas Dale (1700-1750): Botany in the transatlantic Republic of Letters.

PubMed

Cook, William J

2012-03-01

This paper seeks to provide a full account of the life and career of Dr. Thomas Dale (1700-1750), with particular reference to his botanical works and correspondence. Born in Hoxton, London, Dale studied medicine at Leiden and engaged fully in the social, literary and epistolary network in which botany was practised in eighteenth-century England. In 1730, however, Dale relocated to the British colonial port of Charles Town, South Carolina. Here he continued to engage in a transatlantic network of botanical exchange and discussion, corresponding on equal and reciprocal terms with his former colleagues in England. Where Dale differs from naturalists in South Carolina before him is that his motives for pursuing botany and for corresponding with English naturalists were located firmly in the New World. Such a conclusion forms a valuable, albeit small contribution to models for the development of national scientific cultures in the imperial world. Similarly, Dale's pursuit of botanical information in South Carolina provides a small amount of material with which to illustrate currently fashionable models for the mediated exchange and circulation of scientific knowledge.

To describe the management and outcome of limb fractures in small domestic equids treated with a modified Thomas splint-cast combination (MTSCC). Retrospective case series. Client owned horses and donkeys. Medical records, including radiographs, were reviewed for details of animals diagnosed with a limb fracture and treated by external coaptation using a MTSCC (2001-2012). Follow-up >6 months after discharge was obtained via telephone consultation with owners or veterinarians. Nine horses and 4 donkeys were identified with fractures of the tibial diaphysis (n = 4), ulna (n = 3), distal metatarsus (n = 2), proximal metacarpus (n = 1), radial diaphysis (n = 1), calcaneus (n = 1), and distal femoral physis (n = 1). Follow-up was available for 12 equids, of which 8 (67%) recovered from the fracture and became pasture sound. Six equids developed obvious external deformation of the affected limb. Selected small equids with long bone fractures, and without athletic expectations, can be managed with external coaptation using an MTSCC. The owner should be informed that the treatment is considered a salvage procedure. © 2017 The American College of Veterinary Surgeons.

Hauge, A

2000-12-10

Thomas H. Huxley (1825-1895) was an English physician and biologist who had a deep impact on the Victorian age. More than any other at his time he introduced scientifically based values. As a member of London's school board he brought science into the curriculum, encouraging school-children to ask questions and to make their own observations. Huxley came from a lower middle class family with little money. By sheer determination and hard work he managed to get a medical education at Charing Cross Hospital Medical School. He then obtained a posting on H.M.S. Rattlesnake, which gave him a chance to explore the southern seas and to study marine species. The results were published by the Royal Society of which Huxley became a member at the age of 26, and later its president. After several years of uncertainty he secured a position at the Royal School of Mines, which he transformed into the Imperial College of Science. He was a prolific scientist with wide interests, doing valuable work in paleontology, taxonomy and ethnology. Huxley wrote numerous essays on philosophy and scientific subjects. He coined the word agnostic to explain his attitude to Christian dogma. His style was clear and direct, and his essays still read very well. However, Huxley is now mostly, perhaps unfairly, remembered for his defence of Darwin's theory of evolution. In his book Evidence as to man's place in nature, Huxley, in contrast to Darwin, deals with the evolution of humans, mainly based on comparative anatomy. Huxley advocated a firmly held belief that scientific truths will have a liberating effect on the minds of men. His lectures on scientific subjects attracted large audiences of people who had not had the benefit of a higher education.

Thomas M. Donahue, one of the nation's leading space and planetary scientists and a pioneer of space exploration, died Saturday October 16, 2004, from complications following heart surgery. The Edward H. White II Distinguished University Professor of Planetary Science at the University of Michigan, Tom shaped space exploration through his scientific achievements and policy positions. His work started with the first use of sounding rockets following World War II and continued for almost 60 years. Tom was born in Healdton, Oklahoma on May 23, 1921 to Robert Emmet and Mary (Lyndon) Donahue. His father was a plumber in the oil fields when Tom was born (Healdton OK was an oil town) and worked as a plumber in Kansas City for a time. Tom grew up in Kansas City, graduating in 1942 from Rockhurst College in that city with degrees in classics and physics. His graduate work in physics at Johns Hopkins University was interrupted by service in the Army Signal Corps. He obtained his PhD degree in atomic physics from Hopkins in the fall of 1947. After three years as a post-doctoral research associate and assistant professor at Hopkins, Tom joined the University of Pittsburgh Physics Department in 1951. At Pittsburgh he organized an atomic physics and atmospheric science program that led to experimental and theoretical studies of the upper atmosphere of the Earth and other solar system planets with instruments flown on sounding rockets and spacecraft. He became Professor of Physics in 1959 and eventually Director of the Laboratory for Atmospheric and Space Sciences and the Space Research Coordination Center at the University. In 1960 he spent a sabbatical year on a Guggenheim Fellowship at the Service d'Aeronomie in Paris, which began collaborations with French colleagues that flourished for more than 40 years. In 1974 he became the Chairman of the Atmospheric and Oceanic Science Department, University of Michigan, a position he held until 1981. In 1986, he was named the Henry

The Maastricht-Duke bridge: An era of mentoring in clinical research - A model for mentoring in clinical research - A tribute to Dr. Galen Wagner.

Meijs, Loek; Zusterzeel, Robbert; Wellens, Hein Jj; Gorgels, Anton Pm

With the passing of Dr. Galen Wagner, an exceptional collaboration between Maastricht University Medical Center, The Netherlands, and Duke Clinical Research Institute, USA, has come to an end. This article focuses on the background of what Galen coined the Maastricht-Duke bridge (MD-bridge), its merits, limitations and development throughout the years, and his special role. Between 2004 and 2015, 23 Maastricht University medical students and post-graduate students were enrolled in the 4-month research elective, mentored by Galen and the Maastricht co-mentor. They were asked to complete a survey about their MD-bridge experience. Sixteen out of the 23 students responded. None but 1 participant had prior research experience. Following their MD bridge-program most participants published 1 or more manuscripts and/or presented their research in an international setting. They felt they had full responsibility as a leader of their project with all participants developing meaningful skills useful in their current job. Fourteen out of 16 would recommend the MD-bridge experience to others. Participants considered the program of great value for their personal growth and independence, giving a feeling of achievement. In addition, for some participants it led to careers in foreign countries including medical practice and research, or obtaining PhDs. With Galen's impressive career of mentoring students, including the 23 MD-bridge participants, he has left behind an amazing concept of self-development in research and personal life. The successes of the MD-bridge prove that it is possible for students to be young investigators during or just after medical school with the potential to contribute to developing meaningful skills and noteworthy careers. Collaborations between international universities, such as the MD-bridge, are feasible and should be embraced by other institutions. Published by Elsevier Inc.

Absorption spectra of thin films of glycine (Gly), alanine (Ala), valine (Val), serine (Ser), leucine (Leu), phenylalanine (Phe) and methinine (Met) were measured in absolute values of absorption cross section σ( E) for the photon energy E from 3 to 250 eV. We translated σ( E) into the optical oscillator strength distribution df/dE and we examined the Thomas-Reiche-Kuhn sum rule [Hirschfelder, J.O., Curtiss, C.F., Bird, R.B., 1954. Molecular Theory of Gases and Liquids. Wiley, New York, p. 890]. We concluded that T-R-K sum rule was correctly applicable for such relatively large size of biomolecules.

Statistical mechanics of light elements at high pressure. VI - Liquid-state calculations with Thomas-Fermi-Dirac theory

1984-01-01

A model free energy is developed for hydrogen-helium mixtures based on solid-state Thomas-Fermi-Dirac calculations at pressures relevant to the interiors of giant planets. Using a model potential similar to that for a two-component plasma, effective charges for the nuclei (which are in general smaller than the actual charges because of screening effects) are parameterized, being constrained by calculations at a number of densities, compositions, and lattice structures. These model potentials are then used to compute the equilibrium properties of H-He fluids using a charged hard-sphere model. The results find critical temperatures of about 0 K, 500 K, and 1500 K, for pressures of 10, 100, and 1000 Mbar, respectively. These phase separation temperatures are considerably lower (approximately 6,000-10,000 K) than those found from calculations using free electron perturbation theory, and suggest that H-He solutions should be stable against phase separation in the metallic zones of Jupiter and Saturn.

Venous thromboembolism (VTE) is one of the leading causes of maternal mortality in the UK. Therefore, timely VTE risk assessment is essential in all obstetrics patients. The Commissioning for Quality and Innovation (CQUIN) payment framework set a target for trusts to complete a VTE risk assessment within 24 hours of admission for 95% of patients. A combination of factors, including lack of integration between multiple IT systems, means that this CQUIN target is currently not being met for obstetric patients in the Hospital Birth Centre at Guys and St Thomas' NHS Trust. This project aims to increase staff awareness of this issue and educate them regarding the correct procedure for VTE assessment. Trialled methods included reminders at staff handovers, use of magnets on the patient whiteboard, posters and stickers displayed around the unit and a loyalty card scheme as incentive to complete assessments. Initial average completion rate was 20.7%, which increased to 67.5% after the first plan, do, study, act (PDSA) cycle with a slight drop to 65.7% after the second cycle. Completion rates increased to 92.3% on the last day of the third PDSA cycle. Although we did not reach the 95% target, we have raised awareness of the importance of recording VTE assessment on electronic systems, and hope we have created sustainable change. PMID:27933149

Thomas-Nicolas Larcheret, teacher in singing, declamation, guitar or lyre and violin, author of music and books, but also inventor of the universal elixir by his name, is a good example of quack of the 19th century. His book Larcheregium ou Dictionnaires spéciaux de mon élixir, ainsi que toute ma doctrine et de mes adhérens (Larcheregium or special Dictionaries of my elixir, as well as all my doctrine and my adherents), published in 1819, deserves a deep study to show the most frequently used arguments by the ones who emphasize the value of their secret remedy. The opportunities are there to present themselves as victims of medical authorities, experts and authorities as a whole, that do not recognize the value of their product. The only acceptable judge for them is the experience reported by the patients who are able to demonstrate the efficacy of the product since they do buy it (probably at a very high price). From this viewpoint, the book of Larcheret is a good example of turning the authorities down and of diatribe against physicians and pharmacists. It is also the demonstration that, even with the Empire's new regulations against secret remedies and quacks, they will still persist for a large part of the 19th century in France.

Quasi-four-body treatment of charge transfer in the collision of protons with atomic helium: II. Second-order non-Thomas mechanisms and the cross sections

A fully quantum mechanical four-body treatment of charge transfer collisions between energetic protons and atomic helium is developed here. The Pauli exclusion principle is applied to both the wave function of the initial and final states as well as the operators involved in the interaction. Prior to the collision, the helium atom is assumed as a two-body system composed of the nucleus, He2+, and an electron cloud composed of two electrons. Nonetheless, four particles are assumed in the final state. As the double interactions contribute extensively in single charge transfer collisions, the Faddeev-Lovelace-Watson scattering formalism describes it best physically. The treatment of the charge transfer cross section, under this quasi-four-body treatment within the FWL formalism, showed that other mechanisms leading to an effect similar to the Thomas one occur at the same scattering angle. Here, we study the two-body interactions which are not classically described but which lead to an effect similar to the Thomas mechanism and finally we calculate the total singlet and triplet amplitudes as well as the angular distributions of the charge transfer cross sections. As the incoming projectiles are assumed to be plane waves, the present results are calculated for high energies; specifically a projectile energy of 7.42 MeV was assumed as this is where experimental results are available in the literature for comparison. Finally, when possible we compare the present results with the other available theoretical data.

Fine Sediment Erosion and Transport to the Near Coastal Zone from Watersheds of St. Thomas, USVI

NASA Astrophysics Data System (ADS)

Benoit, G.; Xuan, Z.

2014-12-01

The US Virgin Islands' landscape is characterized by steep slopes and short distances from ridge peaks to fringing reefs. Fine-grained sediments eroded from predominantly thin soils may be transported rapidly by streams (locally called guts) to the sea and cause stress to corals. We have studied erosion and transport processes on St Thomas by three methods: (1) continuous monitoring of suspended matter in one of the island's few perennial streams, Dorothea Gut, (2) measurement of 137Cs inventories in soil cores taken across the landscape, and (3) evaluation of sediment captured in most of the island's coastal ponds, through which a significant portion of runoff must pass. We find that, for areas that have not been recently disturbed, watersheds retain fine sediments surprisingly well. On the other hand, small patches of land, like building lots that have been recently disturbed and poorly managed, can produce disproportionate amounts of fine sediment. These results differ somewhat from nearby St John, USVI, where unpaved roads are the major source of eroded sediments.

The correct name in Oenothera for Gaura drummondii (Onagraceae)

Abstract In 2007, Wagner and Hoch proposed the new name Oenothera xenogaura W.L.Wagner & Hoch for the species then known as Gaura drummondii (Spach) Torrey & A. Gray (non Oenothera drummondii Hooker, 1834). However, the authors overlooked the availability of Gaura hispida Bentham (1840) for this species. Accordingly, we herewith make the appropriate new combination for this species, Oenothera hispida (Bentham) W.L.Wagner, Hoch & Zarucchi, and place Oenothera xenogaura in synonymy. PMID:26140017

Thomas McKeown and Archibald Cochrane: a journey through the diffusion of their ideas.

In the 1970s Thomas McKeown and Archibald L Cochrane were two of the most influential voices in criticizing the dominance of medical thinking. A bibliometric study of the citations to McKeown's The Role of Medicine: Dream, Mirage or Nemesis and Cochrane's Effectiveness and Efficiency: Random Reflections on Health Services was performed from the publication of each book until 1988 to study how their ideas have been disseminated. During the study period 430 papers in the Science Citation Index or the Social Sciences Citation Index cited Cochrane's book, 133 cited McKeown's, and 166 cited both. The citations came mainly from original papers published in journals of internal medicine or public health and epidemiology (35%) and written by authors from the United States or the United Kingdom. Cochrane's book was cited most frequently in medical journals, suggesting a higher degree of penetration of his ideas among medical scientists. Although the dominance of original papers among the citations suggests that these books have been important in stimulating new knowledge, the main problems that McKeown and Cochrane identified--namely, the relatively small impact of clinical medicine on health outcomes and the poor use of scientific methods in clinical practice--are still with us.

To assess the usefulness of percutaneous treatment of abnormalities of the venous tree in extending the survival of external Thomas shunts (TS). Twelve cases of TS were included in a hemodialysis access fistula dysfunction monitoring program and were followed for up to 48 months. The abnormalities found were treated by percutaneous transluminal angioplasty (PTA) or thrombolysis and PTA. Survival curves and the Kaplan-Meier method were used to calculate the likelihood of primary patency (P1), secondary patency (P2), and overall patency (OP). A total of 61 interventions were performed during the period of follow-up. On 12 occasions the fistula was thrombosed; in the rest, increased venous pressure to 150 mmHg or higher was detected during dialysis. Fistulography was performed after washing the thrombosed fistulas with urokinase, and revealed one or more of the following angiographic signs: 1) a short reduction of more than 50% in lumen caliber in the femoral vein adjacent to the anastomosis, present in 52% of the cases (fig. 1); 2) imaging a "jet" of contrast material at the site of entry of the shunt into the femoral vein (fig. 2), present in 22% of the cases; and 3) a filling defect or "flap" at the same site, owing to hyperplastic tissue or piece of thrombus adhering to the intima, present in 34% of the cases (figs. 3-5). This last-mentioned finding ordinarily gave rise to a "valve" effect, whereby injection into the venous branch was feasible but aspiration from the venous branch was difficult or impossible. PTA was carried out and attained anatomical and functional success in 100% of cases. PI was 58%, 33%, 8%, and 0% at 6, 12, 24, and 36 months, respectively; P2 was 100%, 75%, 58%, and 25%; respectively, at those same times. The comparison of the PI and P2 curves was statistically significant; p < 0.001 (table 1). OP was 83%, 66%, 50% and 41% at 12, 24, 36 and 48 months. The comparison of the PI surgical and OP curves was statistically significant; p < 0

Statistical mechanics of light elements at high pressure. V Three-dimensional Thomas-Fermi-Dirac theory. [relevant to Jovian planetary interiors

1983-01-01

A numerical technique for solving the Thomas-Fermi-Dirac (TED) equation in three dimensions, for an array of ions obeying periodic boundary conditions, is presented. The technique is then used to calculate deviations from ideal mixing for an alloy of hydrogen and helium at zero temperature and high presures. Results are compared with alternative models which apply perturbation theory to calculation of the electron distribution, based upon the assumption of weak response of the electron gas to the ions. The TFD theory, which permits strong electron response, always predicts smaller deviations from ideal mixing than would be predicted by perturbation theory. The results indicate that predicted phase separation curves for hydrogen-helium alloys under conditions prevailing in the metallic zones of Jupiter and Saturn are very model dependent.

Obituary: Thomas C. Van Flandern (1940-2009)

Dr. Thomas Charles Van Flandern, an expert in celestial mechanics and cosmology, died January 9, 2009 in Seattle, Washington, of colon cancer. He was 68. Van Flandern was an astronomer at the U.S. Naval Observatory from 1963 to 1983. He developed software to predict and analyze lunar occultations to improve lunar orbital and fundamental star catalog data. In later years he championed increasingly controversial theories. But his 1978 prediction that some asteroids have natural satellites, which was almost universally rejected, was verified when the Galileo spacecraft photographed Dactyl, a satellite of (243) Ida, during its flyby in 1993. Besides astronomy and computers, he had strong interests in biochemistry and nutrition, and he ran a business selling personal computers in the 1980s. Tom Van Flandern was born June 26, 1940 in Cleveland, Ohio, the first child of Robert F. Van Flandern and Anna Mary Haley. His father, a police officer, left the family when Tom Van Flandern was 5. His mother died when he was 16; he and his siblings then lived with their grandmother, Margery Jobe, until he went to college. Tom Van Flandern became interested in astronomy as a child. He used his first telescope, purchased with newspaper delivery earnings, to observe lunar occultations, and then learned how to predict them, sparking a life-long passion for dynamical astronomy. While attending St. Ignatius High School, Van Flandern and fellow student Thomas Petrie organized the Cleveland Moonwatch team to observe the first artificial satellites, the only team without an adult organizer. In 1958, Tom Van Flandern entered Xavier University where he led the Cincinnati Moonwatch team. He learned computer programming at a summer job with General Electric and wrote software to calculate "look angles" from orbital elements. The Cincinnati team became a top producer of observations using these predictions. Tom obtained a B.S. in mathematics from Xavier in 1962. He spent the next year at

Thomas Birch's ‘Weekly Letter’ (1741–66): correspondence and history in the mid-eighteenth-century Royal Society

2014-01-01

Thomas Birch (1705–66), Secretary of the Royal Society from 1752 to 1765, and Philip Yorke, second Earl of Hardwicke (1720–90), wrote a ‘Weekly Letter’ from 1741 to 1766, an unpublished correspondence of 680 letters now housed in the British Library (Additional Mss 35396–400). The article examines the dimensions and purposes of this correspondence, an important conduit of information for the influential coterie of the ‘Hardwicke circle’ gathered around Yorke in the Royal Society. It explores the writers' self-conception of the correspondence, which was expressed in deliberately archaic categories of seventeenth-century news exchange, such as the newsletter, aviso and a-la-main. It shows how the letter writers negotiated their difference in status through the discourse of friendship, and concludes that the ‘Weekly Letter’ constituted for the correspondents a form of private knowledge, restricted in circulation to their discrete group, and as such unlike the open and networked model of Enlightenment science.

Differential effects of adding and removing components of a context on the generalization of conditional freezing.

PubMed

González, Felisa; Quinn, Jennifer J; Fanselow, Michael S

2003-01-01

Rats were conditioned across 2 consecutive days where a single unsignaled footshock was presented in the presence of specific contextual cues. Rats were tested with contexts that had additional stimulus components either added or subtracted. Using freezing as a measure of conditioning, removal but not addition of a cue from the training context produced significant generalization decrement. The results are discussed in relation to the R. A. Rescorla and A. R. Wagner (1972), J. M. Pearce (1994), and A. R. Wagner and S. E. Brandon (2001) accounts of generalization. Although the present data are most consistent with elemental models such as Rescorla and Wagner, a slight modification of the Wagner-Brandon replaced-elements model that can account for differences in the pattern of generalization obtained with contexts and discrete conditional stimuli is proposed.

Puerulus settlement of the western Atlantic spiny lobster, Panulirus argus, was monitored using modified Witham collectors from December 1996 to March 1998 at seven sites around St. Thomas, U.S. Virgin Islands. A total of 605 pueruli were collected from 553 samples for a catch per unit effort (CPUE) for all sites of 1.09 pueruli. The greatest settlement occurred on sites within a recently declared marine reserve, which had an overall CPUE of 1.77 pueruli. Settlement in non-reserve sites was much lower with an overall CPUE of 0.31 pueruli. Pueruli recruitment declined 67% at inshore sites and 53% at offshore sites between July 1992 - April 1994 and February 1997 - March 1998. Also, only 10% of months sampled in 1997-98 had a CPUE > 0.5 compared to 55% in a previous study in 1992 - 1993. Despite the decline in pueruli CPUE in 1997-98 compared to 1992-94, the commercial lobster catch in the 2000-01 fishing season, and by inference the adult lobster population (legal lobster size in the US Virgin Islands is > or = 3.5 cm carapace length), remained stable.

The dynamics of small ({<=}55 atoms) argon clusters ionized by an intense femtosecond laser pulse is studied using a time-dependent Thomas-Fermi model. The resulting Bloch-like hydrodynamic equations are solved numerically using the smooth particle hydrodynamics method without the necessity of grid simulations. As follows from recent experiments, absorption of radiation and subsequent ionization of clusters observed in the short-wavelength laser frequency regime (98 nm) differs considerably from that in the optical spectral range (800 nm). Our theoretical approach provides a unified framework for treating these very different frequency regimes and allows for a deeper understanding of the underlying cluster explosionmore » mechanisms. The results of our analysis following from extensive numerical simulations presented in this paper are compared both with experimental findings and with predictions of other theoretical models.« less

Since October 1949 Werner Forssmann was a regular guest of Prof. Dr. Hugo Wilhelm Knipping in the Medical University Clinic of Cologne. Established himself as urologist in Bad Kreuznach, Werner Forssmann had read about the American further development of heart catherization, which was invented by himself. Prof. Wilhelm Bolt, who was one of the medical station doctors of the Cologne Clinic, had already learned the technique of heart catherization in 1947. Thus, it was routinely performed in patients at the Cologne University Hospital. A close collaboration between Werner Forssmann and our research group (Hugo Wilhelm Knipping, Wilhelm Bolt, Helmut Valentin, Helmut Venrath, Hans Rink, Wildor Hollmann) was established. After the notification that Werner Forssmann had been awarded the Nobel Prize for Medicine in 1956, Hugo Wilhelm Knipping instructed me to help Werner Forssmann with the preparation of his lecture. Details of events in the year 1956 are illustrated. One of the important developments in which Werner Forssmann participated with the Medical University Clinic of Cologne was the selective pulmonary angiography.

It is suspected that land cover alteration on the southern coast of St. Thomas, USVI has increased runoff, degrading nearshore water quality and coral reef health. Chronic and acute changes in water quality, sediment deposition, and coral health metrics were assessed in three zones based upon perceived degree of human influence. Chlorophyll (p<0.0001) and turbidity (p=0.0113) were significantly higher in nearshore zones and in the high impact zone during heavy precipitation. Net sediment deposition and terrigenous content increased in nearshore zones during periods of greater precipitation and port activity. Macroalgae overgrowth significantly increased along a gradient of decreasing water quality (p<0.0001). Coral bleaching in all zones peaked in November with a regional thermal stress event (p<0.0001). However, mean bleaching prevalence was significantly greater in the most impacted zone compared to the offshore zone (p=0.0396), suggesting a link between declining water quality and bleaching severity.

Transforming an industrial giant. Interview by Thomas A. Stewart and Louise O'Brien.

von Pierer, Heinrich

2005-02-01

In his 12 years at the helm of Siemens, CEO Heinrich von Pierer designed and directed a major transformation. Taking this German icon from a technically superb but slow-moving industrial giantto a disciplined yet nimble multinational has posed enormous challenges. Since 1992, Siemens has revamped its portfolio of businesses, expanded its reach into 192 countries, and created a more local-market-driven culture, gaining recognition as one of the best-managed and most competitive companies in the world. In this edited interview with HBR editor Thomas A. Stewart and consulting editor Louise O'Brien, von Pierer describes the requirements for transformation and culture change and how he broke down historical barriers at Siemens. He shares his insights about portfolio restructuring, his lessons from competing with GE, and the pros and cons of being based in Europe versus America. He reflects on the true start of globalization after the fall of the Berlin wall and on how dramatically the company needed to change in order to counter the resulting pricing pressures across all of its businesses. He talks, too, about the biggest challenge on his successor's desk-"the particular challenge of China;" he says. Amid all these topics, von Pierer reiterates the importance of people: "We all talk about people as our most important resource, but as a matter of fact, who's really taking care of people?... We need [their] backing. We can't afford to run into a situation where people no longer accept what we do."

Custer, T.W.; Sparks, D.W.; Sobiech, S.A.; Hines, R.K.; Melancon, M.J.

1996-01-01

Farm-raised l2-month-old female mallards (Anas platyrhynchos) were released at the Winston-Thomas sewage treatment plant, Bloomington, Indiana. Five mallards were sacrificed at the start of the study and at approximately 10-day intervals through day 100. Concentrations of polychlorinated biphenyls (PCBs) in carcasses increased linearly with time of exposure and exceeded 16 mcg/g wet weight by day 100; PCBs in breast muscle exceeded 3.9 mcg/g by day 100. These PCB values are among the highest recorded for wild or sentinel waterfowl. PCB concentrations in breast muscle (26-523 mcg/g lipid weight) were 50-1,000 times greater than human consumption guidelines for edible poultry in Canada (0.5 mcg/g lipid weight) and 9-176 times greater than consumption guidelines for edible poultry in the United States (3.0 mcg/g lipid weight). Additionally, PCB concentrations in carcass and breast muscle exceeded the threshold of the Great Lakes Sport Fish Consumption Advisory 'do not eat' category (1.9 mcg/g wet weight) by day 20 and day 50, respectively. Hepatic cytochrome P450-associated monooxygenases including BROD (benzyloxyresorufin-O-dealkylase), EROD (ethoxyresorufin-O-dealkylase), and PROD (pentoxyresorufin-O-dealkylase) were induced over 5-fold compared to reference mallards. BROD, EROD, and PROD were each significantly correlated to total PCBs and to the toxicity of selected PCB congeners, relative to 2,3,7,8-tetrachlorodibenzo-p-dioxin.

The Development of Genetics in the Light of Thomas Kuhn's Theory of Scientific Revolutions.

PubMed

Portin, Petter

2015-01-01

The concept of a paradigm is in the key position in Thomas Kuhn's theory of scientific revolutions. A paradigm is the framework within which the results, concepts, hypotheses and theories of scientific research work are understood. According to Kuhn, a paradigm guides the working and efforts of scientists during the time period which he calls the period of normal science. Before long, however, normal science leads to unexplained matters, a situation that then leads the development of the scientific discipline in question to a paradigm shift--a scientific revolution. When a new theory is born, it has either gradually emerged as an extension of the past theory, or the old theory has become a borderline case in the new theory. In the former case, one can speak of a paradigm extension. According to the present author, the development of modern genetics has, until very recent years, been guided by a single paradigm, the Mendelian paradigm which Gregor Mendel launched 150 years ago, and under the guidance of this paradigm the development of genetics has proceeded in a normal fashion in the spirit of logical positivism. Modern discoveries in genetics have, however, created a situation which seems to be leading toward a paradigm shift. The most significant of these discoveries are the findings of adaptive mutations, the phenomenon of transgenerational epigenetic inheritance, and, above all, the present deeply critical state of the concept of the gene.

Abstract During the preparation of the Vascular Flora of the Marquesas Islands three new species of Cyrtandra (Gesneriaceae) have come to light and are described herein: C. uapouensis W. L. Wagner & Lorence, C. uahukaensis W. L. Wagner & Lorence, and C. kenwoodii W. L. Wagner & A. J. Wagner. Amended descriptions of the eight previously described Marquesan species are also provided as well as a key to the species. With the description of these the new species Cyrtandra in the Marquesas Islands consists of 11 species, six of which have been included in recent molecular phylogenetic studies of Pacific Cyrtandra, and appear to have arisen from one original introduction. If the other five species are members of this Marquesas clade then Cyrtandra would represent the largest lineage of Marquesas vascular plants. Psychotria is largest genus in the Marquesas Islands with 13 species, but is thought to consist of three separate lineages. PMID:24399899

Sir Thomas Brisbane's Legacy to Colonial Science: Colonial Astronomy at the Parramatta Observatory, 1822-1848

2004-12-01

Sir Thomas Makdougall Brisbane's legacy to colonial science derives from his initiative in establishing a privately owned observatory in the southern hemisphere, the Parramatta Observatory, during his term as Governor of the Colony of New South Wales from 1822 to 1825. In this paper a discussion is given of the origin and setting up of Brisbane's Parramatta Observatory, including the recruitment and employment of Carl Rümker and James Dunlop. An account is given of the choice of the work undertaken at Parramatta Observatory when it was privately owned by Brisbane such as the rediscovery of Encke's Comet in 1822, the publication of a catalogue of 7,385 southern stars in 1835 and measurements of earthly phenomena such as the weather, the temperature of the interior of the Earth and the figure of the Earth. An investigation is made of the ensuing struggles as the Parramatta Observatory moved from a private, gentlemanly endeavour to a more accountable public-sector institution in a distant colony of Britain. The main events concerning the public Parramatta Observatory are chronicled from 1826 to 1830 during the years when Rümker worked at the Observatory. A discussion is given of the period 1831 to 1848 at the Parramatta Observatory during Dunlop's term of public office, concluding with an account of the decay and demolition of the observatory.

The Guy's and St Thomas's NHS Foundation Trust @home service: an overview of a new service.

PubMed

Lee, Geraldine A; Titchener, Karen

2017-03-01

Hospital in the home is a relatively new concept within the UK healthcare system. The Guy's and St Thomas's NHS Foundation Trust (GSTT) @home service 'Bringing hospital care to your home' was commissioned by Lambeth and Southwark CCG in 2014 to provide acute care in the patients' place of residence by facilitating rapid discharge from hospital. The service is designed for 260-280 referrals each month from local hospitals, London Ambulance Service, GPs, district nurses and palliative care services. The GSTT@home provides intensive care for a short episode through multidisciplinary team work with the aim of returning the patient to their prior health status following an acute episode of ill health. The main criteria for referrals are adults, living within Lambeth or Southwark with an acute onset of illness often with acute exacerbations of chronic conditions. Care is delivered using 25 clinical pathways using integrated care teams, including those for respiratory disease, heart failure and palliative care services. Recently, the service extended to include overnight palliative care. As care shifts from hospital to the community, it is envisaged that these types of programmes will become an essential component of care provision. This paper describes the service and presents initial service evaluation data.

Reduction of the Hawaiian genus Platydesma into Melicope section Pelea (Rutaceae) and notes on the monophyly of the section.

PubMed

Appelhans, Marc S; Wood, Kenneth R; Wagner, Warren L

2017-01-01

Platydesma , an endemic genus to the Hawaiian Islands containing four species, has long been considered of obscure origin. Recent molecular phylogenetic studies have unequivocally placed Platydesma within the widespread genus Melicope as sister to the rest of the Hawaiian species of Melicope . This makes submerging Platydesma into Melicope necessary. We make the necessary new combinations: Melicope cornuta (Hillebr.) Appelhans, K.R. Wood & W.L. Wagner, M. cornuta var. decurrens (B.C.Stone) Appelhans, K.R. Wood & W.L. Wagner, M. remyi (Sherff) Appelhans, K.R. Wood & W.L. Wagner, and M. rostrata (Hillebr.) Appelhans, K.R. Wood & W.L. Wagner. An additional species that has been recognized within Platydesma should now be recognized under its original name M. spathulata A. Gray. All Hawaiian species belong to Melicope section Pelea. Our molecular phylogenetic studies also showed that in addition to merging Platydesma into section Pelea, five species described from New Caledonia need to be excluded from the section in order to achieve monophyly of section Pelea.

Making history: Thomas Francis, Jr, MD, and the 1954 Salk Poliomyelitis Vaccine Field Trial.

Lambert, S M; Markel, H

This article focuses on the poliomyelitis vaccine field trial directed by Thomas Francis,Jr, MD, of the University of Michigan Vaccine Evaluation Center and sponsored by the National Foundation for Infantile Paralysis (NFIP) or, as it was better known to the public, the March of Dimes. It was a landmark in the widescale testing of a vaccine and the ethical use of human subjects. Millions of American parents readily volunteered their healthy children to participate. A total of 150,000 volunteers, including schoolteachers, physicians, nurses, and health officers all endorsed the study and donated their time and effort to make it successful. Avoiding the use of marginalized groups, the field trial purposefully did not involve institutionalized children; instead, it was based in 15,000 public schools in 44 of the 48 states as clinic sites. A group of 650,000 children received some type of injection, either the vaccine or a placebo, and another 1.18 million served as controls. The field trial depended, most essentially, on both public support and the participation of millions of children who remained enrolled in a study that required a series of 3 injections and a 6-month evaluation period. Enlisting the huge number of participants presented practical examples of the difficulties in experimenting on human subjects. On April 26, 1954, Randy Kerr, a participant or "Polio Pioneer" as the children involved were called, received the first inoculation of the Salk poliomyelitis vaccine. The nationwide study "designed to test the safety and efficacy" of the Salk vaccine had officially begun.

Thomas Mann's Tonio Kröger: a study of the protagonist's emergence from the schizoid to the depressive position.

PubMed

Zlotnick-Woldenberg, C

2000-01-01

The protagonist of Thomas Mann's novella Tonio Kröger is examined in terms of object-relational theory. This approach is briefly compared with the interpretation that might be offered by structural theorists. Kröger, the son of an authoritarian and prototypical Germanic father and an artistic and sensuous mother from the south, is tormented by what he sees as his dual heritage. Unable to accept that he can be both an artist and a respectable member of bourgeois society, he employs splitting as a primary defense mechanism both intrapsychically and interpersonally, projecting these opposing ideologies onto others including Hans, Inge, and Lisabetta. Alternately idealizing and demonizing these characters, projections of his internal conflict, he is unable to achieve an integrated sense of himself or others, functioning primarily in the schizoid position. His emergence from the schizoid into the more mature depressive position, having been foreshadowed in a series of dream sequences, occurs at the end of the work when he comes to accept the view that artistic impulses and bourgeois discipline are not incompatible.

Despite the great diversity of coccidians, to our knowledge, no coccidian infections have been described in Oecomys spp. In this context, we examined Oecomys mamorae Thomas (Rodentia: Cricetidae) from the Brazilian Pantanal for infections with enteric coccidia. Nine individuals were sampled, and one was found to be infected. The oöcysts were recovered through centrifugal flotation in sugar solution. Using morphological and morphometric features, we described a new species of Cystoisospora Frenkel, 1977. Sporulated oöcysts were ovoidal 20.0-29.1 × 16.4-23.2 (26.7 × 21.2) µm and contained two sporocysts, 12.9-19.1 × 9.4-13.9 (16.4 × 12.4) µm, each with four banana-shaped sporozoites. Polar granule and oöcyst residuum were both absent. We documented the developmental forms in the small intestine and described the histopathological lesions in the enteric tract. Our results indicate that the prevalence of Cystoisospora mamorae n. sp. in O. mamorae is low, and tissue damage in the enteric tract is mild, even in the presence of coccidian developmental stages.

Knee arthrodesis in failed total knee arthroplasty with severe osteolysis and ipsilateral long-stem total hip arthroplasty.

We report a case of knee fusion after a failed total knee arthroplasty (TKA) with severe osteolysis including the epicondyle and ipsilateral total hip arthroplasty (THA) with long Wagner revision stem (Sulzer Orthopedics, Baar, Switzerland). The conventional devices for arthrodesis were unavailable in this case because of the long Wagner revision stem and poor bone stock. A connector was made between the long Wagner revision stem and an intramedullary nail (IM nail; Solco, Seoul, Korea). The custom-made connector was coupled with a femoral stem by cylindrical taper fit with additional cement augmentation and an intramedullary nail by screws. Osseous fusion was achieved without pain or instability.
