Wu, Weihao

During the next major shutdown (2019-2020), the ATLAS experiment at the LHC will adopt the Front-End Link eXchange (FELIX) system as the interface between the data acquisition, detector control and TTC (Timing, Trigger and Control) systems and new or updated trigger and detector front-end electronics. FELIX will function as a router between custom serial links from front-end ASICs and FPGAs to data collection and processing components via a commodity switched network. Links may aggregate many slower links or be a single high bandwidth link. FELIX will also forward the LHC bunch-crossing clock, fixed latency trigger accepts and resets received from the TTC system to front-end electronics. The FELIX system uses commodity server technology in combination with FPGA-based PCIe I/O cards. The FELIX servers will run a software routing platform serving data to network clients. Commodity servers connected to FELIX systems via the same network will run the new Software Readout Driver (SW ROD) infrastructure for event f...

Tribute to Erwin Felix Lewy-Bertaut

International Nuclear Information System (INIS)

2006-01-01

Erwin Lewy (alias Felix Bertaut) was born in 1913 in Germany, he emigrated to France where he undertook graduate studies in chemistry. Then, he joined the powder central laboratory where he learnt how to use international tables for structure determination. His thesis work was the X-ray study of the statistical distribution of the size of iron grains. The method Bertaut developed is still a reference in powder granulometry. Bertaut was also interested in the nascent neutron diffraction method and he flew to the United-States to improve his knowledge on this topic. Felix Bertaut created the neutron diffraction laboratory in the atomic research center in Grenoble and later he headed the CNRS' crystallography laboratory till 1982. Felix Bertaut and his laboratories became internationally renowned in crystallography, neutron diffraction and magnetism. He favored the scientific cooperation between France and Germany that led to the creation of the Laue-Langevin Institute (ILL). The ILL became European and was a key partner for building the European Synchrotron Facility (ESRF) in Grenoble. Bertaut was elected as a full member of the French Academy of Sciences in 1979, he died in 2003. (A.C.)

From the ATLAS Phase-I upgrade and onward, new or upgraded detectors and trigger systems will be interfaced to the data acquisition, detector control and timing (TTC) systems by the Front-End Link eXchange (FELIX). FELIX is the core of the new ATLAS Trigger/DAQ architecture. Functioning as a router between custom serial links and a commodity network, FELIX is implemented by server PCs with commodity network interfaces and PCIe cards with large FPGAs and many high speed serial fiber transceivers. By separating data transport from data manipulation, the latter can be done by software in commodity servers attached to the network. Replacing traditional point-to-point links between Front-end components and the DAQ system by a switched network, FELIX provides scaling, flexibility uniformity and upgradability. Different Front-end data types or different data sources can be routed to different network endpoints that handle that data type or source: e.g. event data, configuration, calibration, detector control, monito...

The FELIX Collaboration proposes the construction of a full acceptance detector for the LHC, to be located at Intersection Region 4, and to be commissioned concurrently with the LHC. The primary mission of FELIX is the study of QCD: to provide comprehensive and definitive observations of a very broad range of strong-interaction processes. This document contains a description of the detector concept including details of the individual detector elements and their performance characteristics, an extensive discussion of the physics menu, and the plans for integration of FELIX into the collider lattice and physical environment.

Summary of sensor evaluation for the Fusion ELectromagnetic Induction eXperiment (FELIX)

International Nuclear Information System (INIS)

Knott, M.J.

1982-08-01

As part of the First Wall/Blanket/Shield Engineering Test Program, a test bed called FELIX (Fusion ELectromagnetic Induction eXperiment) is now under construction at ANL. Its purpose will be to test, evaluate, and develop computer codes for the prediction of electromagnetically induced phenomenon in a magnetic environment modeling that of a fusion reaction. Crucial to this process is the sensing and recording of the various induced effects. Sensor evaluation for FELIX has reached the point where most sensor types have been evaluated and preliminary decisions are being made as to type and quantity for the initial FELIX experiments. These early experiments, the first, flat plate experiment in particular, will be aimed at testing the sensors as well as the pertinent theories involved. The reason for these evaluations, decisions, and proof tests is the harsh electrical and magnetic environment that FELIX presents

Evolution of transverse modes in FELIX macropulses

Weits, H.H.; Lin, L.; Werkhoven, G.H.C. van

1995-01-01

We present ringdown measurements of both the intracavity beam, using a low reflection beamsplitter, as well as the hole-outcoupled beam of FELIX, the intracavity measurements being taken at various sets of transverse coordinates. Recent measurements show a significant difference in the decay of the signals at different radial positions, suggesting the presence of higher order transverse modes. The formation of transverse modes depends on the properties of the cold cavity and its losses (i.e. resonator parameters, diffraction and outcoupling at the hole, absorption and edge losses on the mirrors, waveguide clipping), as well as on the gain mechanism. Both simulations with the axisymmetric ELIXER code and previous hole-outcoupled measurements indicated a substantial energy content of the 2nd or 4th Gauss-Laguerre (GL) mode for the 20-30 μm regime of FELIX. Moreover, as FELIX has a phase degenerate cavity, the fundamental and higher order transverse modes can interplay to create a reduced outcoupling efficiency at the hole. For example, in contrast to the decay rate of 13% per roundtrip that we would expect for a pure gaussian beam when we include a loss of 6% for the reflection at the intracavity beamsplitter, recent simulations indicate a decay rate as high as 23% of the hole-outcoupled signal. In this case the 2nd order GL mode contains 30% of the total intracavity power. The effect of transverse modes on subpulses in the limit cycle regime is an interesting aspect. As soon as a subpulse is losing contact with the electrons, its transverse pattern will exhibit an on-axis hole after a few roundtrips, according to the simulations. This process could mean that the subpulses are less pronounced in the hole-outcoupled signal of FELIX 1

Felix Mendelssohn is one of the great classical composers of all time. During his short lifetime in the first half of the nineteenth century, he reached enormous heights as a composer, conductor, and leader in the world of music. Nearly one hundred years after his death, the Nazi regime attempted, unsuccessfully, to erase his music and his memory from history. Since the end of World War II, there has been a resurgence in interest in the life and music of Felix Mendelssohn and that of his sister, Fanny. Felix Mendelssohn died in 1947 at the age of 38. Both of his sisters died suddenly at the ages of 42 and 45. There is insufficient laboratory or post-mortem data to make a medical diagnosis with certainty. However, based on the information available to us, we speculate that Mendelssohn suffered a subarachnoid or intracerebral hemorrhage. The differential diagnosis of familial stroke syndrome is discussed.

Experiments in high-energy physics (HEP) and related fields often impose constraints and challenges on data acquisition systems. As a result, these systems are implemented as unique mixtures of custom and commercial-off-the-shelf electronics (COTS), involving and connecting radiation-hard devices, large high-performance networks, and computing farms. FELIX, the Frontend Link Exchange, is a new PC-based general purpose data routing device for the data-acquisition system of the ATLAS experiment at CERN. Performance is a very crucial point for devices like FELIX, which have to be capable of processing tens of gigabyte of data per second. Thus it is important to understand the performance limitations for typical workloads on modern hardware. We present an analysis of a packet processing algorithm that is used in FELIX, and show how the PC system's memory architecture plays a key factor in the overall data throughput achieved by the application. Finally, we present optimizations that increase the processing throug...

Phylogenetic relationships among zooxanthellae (Symbiodinium) associated to excavating sponges (Cliona spp.) reveal an unexpected lineage in the Caribbean.

Granados, C; Camargo, C; Zea, S; Sánchez, J A

2008-11-01

Phylogenetic relationships of symbiotic dinoflagellate lineages, distributed in all tropical and subtropical seas, suggest strategies for long distance dispersal but at the same time strong host specialization. Zooxanthellae (Symbiodinium: Dinophyta), which are associated to diverse shallow-water cnidarians, also engage in symbioses with some sponge species of the genus Cliona. In the Caribbean, zooxanthellae-bearing Cliona has recently become abundant due to global warming, overfishing, and algae abundance. Using molecular techniques, the symbionts from five excavating species (Clionacaribbaea, C. tenuis, C. varians, C. aprica and C. laticavicola) from the southern and southwestern Caribbean were surveyed. Several DNA sequence regions were used in order to confirm zooxanthellae identity; 18S rDNA, domain V of chloroplast large subunit (cp23S), internal transcribed spacer 2 (ITS2), and ITS2 secondary structure. Sequence analyses corroborated the presence of three zooxanthellae clades: A, B, and G. Presence of clades A and B in common boring sponges of the Caribbean fit with the general pattern of the province. The discovery of clade G for the first time in any organism of the Atlantic Ocean leads us to consider this unusual finding as a phylogenetic relict through common ancestors of sponge clades or an invasion of the sponge from the Indo-Pacific.

For a conducting material exposed to both a time-varying and a static magnetic field, such as a limiter blade in a tokamak, the induced eddy currents and the deflection arising from those eddy currents can be strongly coupled. The coupling effects reduce the currents and deflections markedly, sometimes an order of magnitude, from the values predicted if coupling is neglected. A series of experiments to study current-deflection coupling were performed using the Fusion Electromagnetic Inductance Experiment (FELIX) facility at Argonne National Laboratory. Magnetic damping and magnetic stiffness resulting from the coupling are discussed, and analytical expressions for induced eddy current and rigid body rotation in the FELIX plate experiment are compared with the experimental results. Predictions for the degree of coupling based on various parameters are made using the analytical model

An improved generation of our 'FELIX 3D Display' is presented. This system is compact, light, modular and easy to transport. The created volumetric images consist of many voxels, which are generated in a half-sphere display volume. In that way a spatial object can be displayed occupying a physical space with height, width and depth. The new FELIX generation uses a screen rotating with 20 revolutions per second. This target screen is mounted by an easy to change mechanism making it possible to use appropriate screens for the specific purpose of the display. An acousto-optic deflection unit with an integrated small diode pumped laser draws the images on the spinning screen. Images can consist of up to 10,000 voxels at a refresh rate of 20 Hz. Currently two different hardware systems are investigated. The first one is based on a standard PCMCIA digital/analog converter card as an interface and is controlled by a notebook. The developed software is provided with a graphical user interface enabling several animation features. The second, new prototype is designed to display images created by standard CAD applications. It includes the development of a new high speed hardware interface suitable for state-of-the- art fast and high resolution scanning devices, which require high data rates. A true 3D volume display as described will complement the broad range of 3D visualization tools, such as volume rendering packages, stereoscopic and virtual reality techniques, which have become widely available in recent years. Potential applications for the FELIX 3D display include imaging in the field so fair traffic control, medical imaging, computer aided design, science as well as entertainment.

The High Voltage CMOS (HV-CMOS) sensors are extensively investigated by the ATLAS collaboration in the High-Luminosity LHC (HL-LHC) upgrade of the Inner Tracker (ITk) detector. A testbeam telescope, based on the ATLAS IBL (Insertable B-Layer) silicon pixel modules, has been built to characterize the HV-CMOS sensor prototypes. The Front-End LInk eXchange (FELIX) system is a new approach to function as the gateway between front-ends and the commodity switched network in the different detectors of the ATLAS upgrade. A FELIX based readout system has been developed for the readout of the testbeam telescope, which includes a Telescope Readout FMC Card as interface between the IBL DC (double-chip) modules and a Xilinx ZC706 evaluation board. The test results show that the FELIX based telescope readout system is capable of sensor calibration and readout of a high-density pixel detector in test beam experiments in an effective way.

Design study of a longer wavelength FEL for FELIX

1995-01-01

We present a design study of FEL3, which will extend the FELIX spectral range towards a few hundred microns. A rectangular waveguide will be used to reduce diffraction losses. Calculations show that with a waveguide gap of 1 cm, only one sinusoidal mode along the guided direction can exist within the FEL gain bandwidth, thus excluding group velocity dispersion and lengthening of short radiation pulses. To incorporate FEL3 in the existing FELIX facility, two options are being considered: to combine FEL3 with FEL1 by insertion of a waveguide into FEL1, and to build a dedicated third beam line for FEL3 after the two linacs. Expected FEL performance: gain, spectrum, power, pulse shape, etc., will be presented based on numerical simulations

FELIX: a PCIe based high-throughput approach for interfacing front-end and trigger electronics in the ATLAS upgrade framework

CERN Document Server

Schreuder, Frans Philip; The ATLAS collaboration

2018-01-01

Starting during the upcoming major LHC shutdown (2019-2021), the ATLAS experiment at CERN will move to the Front-End Link eXchange (FELIX) system as the interface between the data acquisition system and the trigger and detector front-end electronics. FELIX will function as a router between custom serial links and a commodity switch network, which will use industry standard technologies to communicate with data collection and processing components. This presentation will describe the FELIX system design as well as reporting on results of the ongoing development program.

Coherent Protein Dynamics Explored at FELIX

Austin, Robert

2004-01-01

We have discovered that there exists a very narrow (less than 0.02 microns) wide resonance in the amide I band of myoglobin and photoactive yellow protein that can be driven to greater than 30% saturation using very narrow linewidth pump-probe spectroscopy at FELIX. The extraordinary narrowness of this transition and the extraordinary ease of saturation inplies that this band is highly anharmonic and decoupled from the other oscillators in the amide I band. We will present detailed measurments on this discovery and implications for energy flow in proteins.

The performance of the RF system for the Free Electron Laser for Infrared eXperiments (FELIX) is discussed. The RF system provides the input power for a triode gun (1 GHz, 100 W), a prebuncher (1 GHz, 10 kW), a buncher (3 GHz, 20 MW), and two linacs (3 GHz, 8 MW each). The pulse length in the system is 20 μs. The required electron beam stability imposes the following demands on the RF system: a phase stability better than 0.3 deg for the 1 GHz signals and better than 1 deg for the 3 GHz signals; the amplitude stability has to be better than 1% for the 1 GHz and better than 0.2% for the 3 GHz signals.

The ATLAS Phase-I upgrade requires a Trigger and Data Acquisition (TDAQ) system able to trigger and record data from up to three times the nominal LHC instantaneous luminosity. The FELIX system provides this in a scalable, detector agnostic and easily upgradeable way. It is a PC-based gateway, routing between custom radiation tolerant optical links from front-end electronics, via FPGA PCIe Gen3 cards, and a commodity switched Ethernet or InfiniBand network. FELIX enables reducing custom electronics in favor of software on commercial servers. The FELIX system, results of demonstrator, design and testing of prototype are described.

A soluble envelope protein of endogenous retrovirus (FeLIX) present in serum of domestic cats mediates infection of a pathogenic variant of feline leukemia virus.

T-lymphotropic feline leukemia virus (FeLV-T), a highly pathogenic variant of FeLV, induces severe immunosuppression in cats. FeLV-T is fusion defective because in its PHQ motif, a gammaretroviral consensus motif in the N terminus of an envelope protein, histidine is replaced with aspartate. Infection by FeLV-T requires FeLIX, a truncated envelope protein encoded by an endogenous FeLV, for transactivation of infectivity and Pit1 for binding FeLIX. Although Pit1 is present in most tissues in cats, the expression of FeLIX is limited to certain cells in lymphoid organs. Therefore, the host cell range of FeLV-T was thought to be restricted to cells expressing FeLIX. However, because FeLIX is a soluble factor and is expressed constitutively in lymphoid organs, we presumed it to be present in blood and evaluated its activities in sera of various mammalian species using a pseudotype assay. We demonstrated that cat serum has FeLIX activity at a functional level, suggesting that FeLIX is present in the blood and that FeLV-T may be able to infect cells expressing Pit1 regardless of the expression of FeLIX in vivo. In addition, FeLIX activities in sera were detected only in domestic cats and not in other feline species tested. To our knowledge, this is the first report to prove that a large amount of truncated envelope protein of endogenous retrovirus is circulating in the blood to facilitate the infection of a pathogenic exogenous retrovirus. © 2015 The Authors.

Berić Dejan

2012-01-01

Full Text Available The tourism industry is a great potential for the development of Serbia. The main characteristics of the existing and potential tourist offer of Serbia are interesting and diverse natural resources and cultural and historical heritage. Felix Romuliana, established palace of the Roman emperor Galerius, is located in the valley of the Black Timok, near Zaječar and the village of Gamzigrad in eastern Serbia. The palace was built in the late third and early fourth century, as a testamentary construction. This is where the Roman emperor was buried and included among the gods. It is the best preserved example of Roman palatial architecture which in 2007 was added to the List of World Heritage of UNESCO. One of the key tasks of this paper is to point out ways of promoting and popularizing this tourism potential that can be used as a resource for the development of cultural tourism and as such strengthen the position of Serbia''s tourist offer in Europe. The aim of this paper is contained in the presentation of the site Felix Romuliana and extraction of the most important attractiveness through valorization, which on the bases of historical and cultural significance may be activated for tourism purposes.

The ATLAS experiment at CERN is planning full deployment of a new unified optical link technology for connecting detector front end electronics on the timescale of the LHC Run 4 (2025). It is estimated that roughly 8000 GBT (GigaBit Transceiver) links, with transfer rates up to 10.24 Gbps, will replace existing links used for readout, detector control and distribution of timing and trigger information. A new class of devices will be needed to interface many GBT links to the rest of the trigger, data-acquisition and detector control systems. In this paper FELIX (Front End LInk eXchange) is presented, a PC-based device to route data from and to multiple GBT links via a high-performance general purpose network capable of a total throughput up to O(20 Tbps). FELIX implies architectural changes to the ATLAS data acquisition system, such as the use of industry standard COTS components early in the DAQ chain. Additionally the design and implementation of a FELIX demonstration platform is presented and hardware and software aspects will be discussed. (paper)

Review of past experiments at the FELIX facility and future plans for ITER applications

Hua, T.Q.; Turner, L.R.

1993-01-01

FELIX is an experimental test facility at Argonne National Laboratory (ANL) for the study of electromagnetic effects in first wall, blanket, shield systems of fusion reactors. From 1983 to 1986 five major test series, including static and dynamic tests, were conducted and are reviewed in this paper. The dynamic tests demonstrated an important coupling effect between eddy currents and motion in a conducting structure. Recently the U.S. has proposed to the ITER Joint Central Team to use FELIX for testing mock-up components to study electromagnetic effects encountered during plasma disruptions and other off-normal events. The near and long term plans for ITER applications are discussed. (author)

The genome and proteome of a virulent Escherichia coli O157:H7 bacteriophage closely resembling Salmonella phage Felix O1

2009-04-01

Full Text Available Abstract Based upon whole genome and proteome analysis, Escherichia coli O157:H7-specific bacteriophage (phage wV8 belongs to the new myoviral genus, "the Felix O1-like viruses" along with Salmonella phage Felix O1 and Erwinia amylovora phage φEa21-4. The genome characteristics of phage wV8 (size 88.49 kb, mol%G+C 38.9, 138 ORFs, 23 tRNAs are very similar to those of phage Felix O1 (86.16 kb, 39.0 mol%G+C, 131 ORFs and 22 tRNAs and, indeed most of the proteins have their closest homologs within Felix O1. Approximately one-half of the Escherichia coli O157:H7 mutants resistant to phage wV8 still serotype as O157:H7 indicating that this phage may recognize, like coliphage T4, two different surface receptors: lipopolysaccharide and, perhaps, an outer membrane protein.

Electron pulse shaping in the FELIX RF accelerator

Weits, H.H.; Geer, C.A.J. van der; Oepts, D.; Meer, A.F.G. van der

The FELIX free-electron laser uses short pulses of relativistic electrons produced by an RF accelerator. The design target for the duration of these electron bunches was around 3 ps. In experiments we observed that the bunches emit coherently enhanced spontaneous emission (CSE) when they travel through an undulator. It was demonstrated that the power level of the CSE critically depends on the settings of the accelerator. In this article we seek to explain these observations by studying the length and shape of the electron bunches as a function of the settings of the accelerator. A particle-tracking model was used to simulate the acceleration and transport processes. These include bunch compression in a 14-cell travelling wave buncher cavity, acceleration in a travelling wave linear accelerator, and passage through a (dispersive) chicane structure. The effect of the phase setting of the RF accelerating field with respect to the arrival time of the electron bunch in each accelerator structure was studied. The parameter range of the simulations is related to that of an actual free-electron laser experiment using these bunches. We find that, for specific settings of the accelerating system, electron pulses with a length of 350 μm FWHM (1 ps) are produced. The charge in the bunch rises steeply within a distance of 25 μm. This bunch shape explains the high level of coherently enhanced spontaneous emission observed in the FELIX laser. (author)

Coupling between angular deflection and eddy currents in the FELIX plate experiment

International Nuclear Information System (INIS)

Turner, L.R.; Cuthbertson, J.W.

1983-08-01

For a conducting body experiencing superimposed changing and steady magnetic field, for example a limiter in a tokamak during plasma quench, the induced eddy currents and the deflections resulting from those eddy currents are coupled. Experimental study of these coupled deflections and currents can be performed with the FELIX (Fusion Electromagnetic Induction Experiment) facility nearing completion at ANL. Predictions of the coupling are described, as computed with the code EDDYNET, which has been modified for this purpose. Effects of the coupling will be readily observable experimentally. In the FELIX plate experiment, the coupling between deflection and eddy currents was readily calculated because the rigid-body rotation of the plate is equivalent to a contrarotation of the applied magnetic fields. For a geometry such as a plasma limiter, in which the eddy currents would cause a deformation of the conducting body, an analysis of the coupling between eddy currents and deformation would require a structural-analysis code and an eddy current code to be simultaneously computing from the same mesh

Case Study of Hurricane Felix (2007) Rapid Intensification

Science.gov (United States)

Colon-Pagan, I. C.; Davis, C. A.; Holland, G. J.

2010-12-01

The forecasting of tropical cyclones (TC) rapid intensification (RI) is one of the most challenging problems that the operational community experiences. Research advances leading to improvements in predicting this phenomenon would help government agencies make decisions that could reduce the impact on communities that are so often affected by these weather-related events. It has been proposed that TC RI is associated to various factors, including high sea-surface temperatures, weak vertical wind shear, and the ratio of inertial to static stability, which improves the conversion of diabatic heating into circulation. While a cyclone develops, the size of the region of high inertial stability (IS) decreases whereas the magnitude of IS increases. However, it’s unknown whether this is a favorable condition or a result of RI occurrences. The purpose of this research, therefore, is to determine if the IS follows, leads or changes in sync with the intensity change by studying Hurricane Felix (2007) RI phase. Results show a trend of increasing IS before the RI stage, followed by an expansion of the region of high IS. This episode is eventually followed by a decrease in both the intensity and region of positive IS, while the maximum wind speed intensity of the TC diminished. Therefore, we propose that monitoring the IS may provide a forecast tool to determine RI periods. Other parameters, such as static stability, tangential wind, and water vapor mixing ratio may help identify other features of the storm, such as circulation and eyewall formation. The inertial stability (IS) trend during the period of rapid intensification, which occurred between 00Z and 06Z of September 3rd. Maximum values of IS were calculated before and during this period of RI within a region located 30-45 km from the center. In fact, this region could represent the eye-wall of Hurricane Felix.

2012-04-01

Full Text Available Friedebert Tuglas’ Felix Ormusson and James Joyce’s Portrait of the Artist as a Young Man were finished in the same year – 1914, but the writing of both novels took the writers almost a decade, a time of searching and exile for both of them. Joyce completely rewrote the initial draft of his novel, entitled Stephen Hero, experimenting with basic forms, such as the short prose piece he called the ”epiphany”. Tuglas’ Felix Ormusson was initially conceived as a three-volume picaresque novel, which was distilled into a single volume of prose fragments arranged as a diary novel: the rest was left unfinished, and exists only in the form of two novella-length fragments. A comparative juxtaposition of the two novels is suggestive, not just because of parallels between the authors’ life trajectories and creative biographies, nor because of similarities between the protagonists, not even by the somewhat deceptive placement in the rubric of the 'Künstlerroman'. Both novels partake of ironic autobiography, and both resonate with the subgenre of the ”diary novel”, increasingly in vogue in European literature of the fin-de-siècle, modelled in turn on the published journal intime. Felix Ormusson and Stephen Dedalus were their authors’ long-time fictional fellow travellers, alter ego’s, in whose confessions one can read the pressing desire to emerge from the provinces and peripheries of Europe toward broader, metropolitan cultural horizons. The protagonists’ quests open onto the problematics of modernism – the split between life and literature, and the burden of ”overreflexivity” which obstructed literary creation and sentimental education. Behind the aesthetic polemics of both novels are shadows of the politics of the era: for Felix Ormusson, the aftermath of the 1905 revolution and political exile, and in the milieu of young Stephen Dedalus, the entanglement of national politics and the Catholic church. In the first part of the

The facility includes the following facilities; (a) a sizable constant field, analogous to a tokamak toroidal field or the confining field of a mirror reactor, (b) a pulsed field with a sizable rate of change, analogous to a pulsed poloidal field or to the changing field of a plasma disruption, perpendicular to the constant field, and (c) a sufficiently large volume to assure that large, complex test pieces can be tested, and that the forces, torques, currents, and field distortions which are developed are large enough to be measured accurately. The development of the necessary computer codes and the experimental program are examined. (U.K.)

Full text: The geothermal 'Felix-1 Mai-Oradea' deposit is situated in the western part of Romania and it is well known long years ago. The waters of this deposit are used in the medical treatments in the two resorts (Felix and 1 Mai) and for heating and swimming pools in Oradea town. The deposit depth (2500-3000 m) determines a high temperature (66-900 deg. C) of these waters also a mineral content of 200-1400 mg/l, the main components being Ca and Mg. First time, during some years, the thermal water was directly used in the central heating radiators from 'Nufarul' residential district. At present a heating switch installation is utilised. The high radium content of these thermal waters comparatively with Italian or Japanese thermal waters suggested us a study of radium deposition on the inner walls of the pipes also in the inner central heating radiators. Analysing these depositions using a high resolution Ge-Li detector, the radium-226 and small quantities of radium-224 and 223 isotopes were registered. Average radium-226 deposition was 1200 Bq/kg.

FELIX experiments and computational needs for eddy current analysis of fusion reactors

International Nuclear Information System (INIS)

Turner, L.R.

1984-01-01

In a fusion reactor, changing magnetic fields are closely coupled to the electrically-conducting metal structure. This coupling is particularly pronounced in a tokamak reactor in which magnetic fields are used to confine, stabilize, drive, and heat the plasma. Electromagnetic effects in future fusion reactors will have far-reaching implications in the configuration, operation, and maintenance of the reactors. This paper describes the impact of eddy-current effects on future reactors, the requirements of computer codes for analyzing those effects, and the FELIX experiments which will provide needed data for code validation

Measurements of reactor-relevant electromagnetic effects with the FELIX facility

Turner, L.R.; Hua, T.Q.; Knott, M.J.; Lee, S.Y.; McGhee, D.G.; Wehrle, R.B.

1986-01-01

In predicting the electromagnetic consequences of a plasma disruption in a tokamak reactor design, a two-dimensional electromagnetic model of the first wall, blanket, and shield (FWBS) system is typically used. The response to a decaying plasma current is then found to be dominated by a single eddy-current mode, with a single L/R time. Recent experiments with the Fusion ELectromagnetic Induction eXperiment (FELIX) facility at Argonne National Laboratory suggest that such modeling can be used to design against electromagnetic forces and torques, but only if a range of values is used for both tau, the plasma decay time, and tau 0 , the L/R time of the FWBS system

Molecular evidence of cryptic speciation in the "cosmopolitan" excavating sponge Cliona celata (Porifera, Clionaidae).

Xavier, J R; Rachello-Dolmen, P G; Parra-Velandia, F; Schönberg, C H L; Breeuwer, J A J; van Soest, R W M

2010-07-01

Over the past several decades molecular tools have shown an enormous potential to aid in the clarification of species boundaries in the marine realm, particularly in morphologically simple groups. In this paper we report a case of cryptic speciation in an allegedly cosmopolitan and ecologically important species-the excavating sponge Cliona celata (Clionaidae, Hadromerida). In the Northeast Atlantic and Mediterranean C. celata displays a discontinuous distribution of its putative growth stages (boring, encrusting, and massive) leading us to investigate its specific status. Phylogenetic reconstructions of mitochondrial (COI, Atp8) and nuclear (28S) gene fragments revealed levels of genetic diversity and divergence compatible with interspecific relationships. We therefore demonstrate C. celata as constituting a species complex comprised of at least four morphologically indistinct species, each showing a far more restricted distribution: two species on the Atlantic European coasts and two on the Mediterranean and adjacent Atlantic coasts (Macaronesian islands). Our results provide further confirmation that the different morphotypes do indeed constitute either growth stages or ecologically adapted phenotypes as boring and massive forms were found in two of the four uncovered species. We additionally provide an overview of the cases of cryptic speciation which have been reported to date within the Porifera, and highlight how taxonomic crypsis may confound scientific interpretation and hamper biotechnological advancement. Our work together with previous studies suggests that overconservative systematic traditions but also morphological stasis have led to genetic complexity going undetected and that a DNA-assisted taxonomy may play a key role in uncovering the hidden diversity in this taxonomic group.

Analysis of the FELIX experiments with cantilevered beams and hollow cylinders

International Nuclear Information System (INIS)

Turner, L.R.; Hua, T.Q.; Lee, S.-Y.

1986-01-01

Experiments have been performed with the FELIX facility at Argonne National Laboratory to study the coupling between eddy currents and deflections and to provide data for validating eddy current computer programs.

Gmal, B.; Weber, J.

1989-01-01

Knowledge of characteristic parameters like evolved power fission yield during an accidental excursion is of essential importance to estimate possible radiological consequences and resulting safety hazards. The computer code 'FELIX' simulates excursion characteristics of aqueous critical assemblies: Starting out from given initial conditions the space-dependent neutron kinetic equations are solved in one-dimensional geometry. Power, fission yield, reactivity and temperature are calculated as a function of time. Reactivity-feedback includes density effects and radiolytic gas voids. Results from calculations are compared with CRAC-experiments. (orig.)

The boring sponge Cliona celata is a nuisance species that can have deleterious effects on eastern oyster Crassostrea virginica growth, condition, and survival. Surprisingly, however, these effects have not been well documented and when examined, results have been equi-vocal. In this study, we provide a direct comparison of growth, condition, and survival of sponge-colonized and uncolonized oysters in southeast North Carolina in 2 separate experiments. In the first experiment, sponge-colonized oysters exhibited significantly slower growth rates, reduced condition, and lower survival relative to uncolonized oysters, although results may have been confounded by oyster source. In the second experiment, using smaller oysters from the same source population, growth rate was again significantly reduced in colonized oysters relative to uncolonized oysters, however neither condition nor survival differed. In field surveys of the same population, colonized individuals across a range of sizes demonstrated significantly reduced condition. Further, condition index was negatively correlated with sponge biomass, which was positively correlated with oyster size, suggesting that the impact of the sponge changes with ontogeny. By investigating clearance rates, tissue isotopic and nutrient content, as well as caloric value, this study provides further evidence that sponge presence causes the oysters to divert energy into costly shell maintenance and repair at the expense of shell and somatic growth. Thus, although variable, our results demonstrate negative impacts of sponge infestation on oyster demographics, particularly as oysters grow larger.

Highly fractionated rare-earth elements in ferromagnesian chondrules from the Felix (CO3) meteorite

Here we describe two ferromagnesian chondrules from the Felix (Ornans-subtype) carbonaceous chondrite which carry a marker signature of REE (rare earth element) fractionation in the nebula. Both show positive Ce and Yb anomalies and one exhibits a light/heavy REE fractionation. On the basis of the REE characteristics of these chondrules, as well as those of the authors' work on Allende (CV) [N Geochim. Cosmochim. Acta. in press], we suggest that one of the precursor materials of chondrules in CO-CV carbonaceous chondrites is a high-temperature condensate from the nebular gas. (author)

Felix Berezin Life and death of the mastermind of supermathematics

CERN Document Server

Shifman, M

2007-01-01

Felix Berezin was an outstanding Soviet mathematician who in the 1960s and 70s was the driving force behind the emergence of the branch of mathematics now known as supermathematics. The integral over the anticommuting Grassmann variables that he introduced in the 1960s laid the foundation for the path integral formulation of quantum field theory with fermions, the heart of modern supersymmetric field theories and superstrings. The Berezin integral is named for him, as is the closely related construction of the Berezinian, which may be regarded as the superanalog of the determinant. This book features a masterfully written memoir by Berezin's widow, Elena Karpel, who narrates a remarkable account of Berezin's life and his struggle for survival under the totalitarian Soviet regime. Supplemented with recollections by his close friends and colleagues, Berezin's accomplishments in mathematics, his novel ideas and breakthrough works, are reviewed in two articles written by Andrei Losev and Robert Minlos.

Rb-Sr systematics have been applied on rocks from the Sao Felix do Xingu region, in the southeastern part of the State of Para. An age of 2716 ± 34 Ma with IR of 0.70292 ± 0.00030 (MSWD = 1.54) and an age of 2677 ± 50 Ma with IR of 0.70161 ± 0.00022 (MSWD = 5.21) had been obtained for a granitic body and a tonalitic body respectively, both of them associated to the green stones belts that occur in this area. Gneisses from the Xingu complex gave an age of 2574 ± 57 Ma with an IR of 0.70416 ± 0.00054 (MSWD = 5.06). An age of 1653 ± 14 Ma with IR of 0.70823 ± 0.02361 (MSWD = 1.71) had been obtained for the Velho Guilherme granite that crosscut the granite-green stones terrains. Such geochronological data show the existence of a magmatic event between 2.72 Ga and 2.68 Ga and permit us to conclude on the archaean age of the green stones terrains. (author)

3-D transient eddy current calculations for the FELIX cylinder experiments

International Nuclear Information System (INIS)

Davey, K.R.; Turner, L.R.

1986-12-01

The three-dimensional eddy current transient field problem is formulated first using the U-V method. This method breaks the vector Helmholtz equation into two scalar Helmholtz equations. Null field integral equations and the appropriate boundary conditions are used to set up an identification matrix which is independent of null field point locations. Embedded in the identification matrix are the unknown eigenvalues of the problem representing its impulse response in time. These eigenvalues are found by equating the determinant of the identification matrix to zero. When this initial forcing function is Fourier decomposed into its spatial harmonics, each Fourier component can be associated with a unique eigenvalue by this technique. The true transient solution comes through a convolution of the impulse response so obtained with the particular external field decay governing the problem at hand. The technique is applied to the FELIX cylinder experiments; computed results are compared to data. A pseudoanalytic confirmation of the eigenvalues so obtained is formulated to validate the procedure

CERN has planned a series of upgrades for the LHC. The last in this current series of planned upgrades is designated the HL-LHC. At the same time, the ATLAS Experiment will be extensively changed to meet the challenges of this upgrade (termed as the “Phase-II” upgrade). The Inner Detector will be completely rebuilt for the phase-II. The TRT, SCT and Pixel will be replaced by the all-silicon tracker, termed as the Inner Tracker (ITk). The read-out of this future ITk detector is an engineering challenge for the routing of services and quality of the data. This document describes the FPGA firmware development that integrates the GBT, Elink and Rx-Tx Cores for communication between the FE-I4 modules and the FELIX read-out system.

Calculations of transient fields in the Felix experiments at Argonne using null field integrated techniques

Han, H.C.; Davey, K.R.; Turner, L.

1985-08-01

The transient eddy current problem is characteristically computationally intensive. The motivation for this research was to realize an efficient, accurate, solution technique involving small matrices via an eigenvalue approach. Such a technique is indeed realized and tested using the null field integral technique. Using smart (i.e., efficient, global) basis functions to represent unknowns in terms of a minimum number of unknowns, homogeneous eigenvectors and eigenvalues are first determined. The general excitatory response is then represented in terms of these eigenvalues/eigenvectors. Excellent results are obtained for the Argonne Felix cylinder experiments using a 4 x 4 matrix. Extension to the 3-D problem (short cylinder) is set up in terms of an 8 x 8 matrix

Sum-frequency generation from molecular monolayers using 14 μm radiation from the FELIX free-electron laser

Sum-frequency generation (SFG) has developed into a widely applied tool for study of surfaces and interfaces where molecules are present. It combines the surface specificity of a second-order nonlinear optical technique with the power of a spectroscopic method, and it can be used under widely varying experimental conditions ranging from UHV to electrochemical cells. The important characteristic of SFG is that it allows one to study the average spatial orientation of a molecular bond in a monolayer of molecules at an interface. Until recently SFG measurements were confined to the frequency interval Y μ > 1700 cm -1 because of a lack of suitable laser sources at wave-lengths λ > 6 μm. So for most molecules only a few vibrational modes and thus intramolecular bonds can be studied. We have developed a universal sum-frequency spectrometer around the FELIX free-electron law that covers the complete molecular fingerprint since we can generate any IR wavelength between 2.75 and 110 fμ at the FELIX facility. We have used this setup for a series of exploratory SFG experiments in a frequency range that was hitherto unexplored in the study of molecular monolayers. We have studied thiol monolayers chemisorbed on a variety of noble metals (Au, Ag, Pt) where we focussed on the C-S stretch vibration at ν = 702 cm -1 (λ = 14.3 μm). We have found spectroscopic features revealing the presence of both the trane and gauche conformers of the adsorbed molecules. The present measurements open a whole new wavelength range for nonlinear optical studies of interfaces

FELIX: A proposal for a free electron laser experiment at Daresbury

International Nuclear Information System (INIS)

Thompson, D.J.

1980-01-01

Although the Stanford Group has clearly demonstrated the feasibility of the free electron laser (of the type working in the low current density regime), and a great deal of theoretical work has been done before and since that time, there is still very little experimental data on such devices and very little practical experience. One of the reasons for this is the cost of suitable electron beam sources. At Daresbury the NINA injector linac is in store and could be recommissioned at much less than the cost of a new machine. It is believed that there is a scientific case for infra-red sources of the FEL type, because of their high power and tunability and that they would complement a synchrotron radiation source which provides intense VUV and X-ray beams. FELIX is a free electron laser experiment using the NINA linac with an output tunable over the range 57-150 μm, proposed as a project to produce experimental data on FEL characteristics and provide practical experience which could lead to a new generation of infra-red sources. The paper will describe a design study which has been carried out and is presently under consideration by the Science Research Council. (orig.)

FELIX-2.0: New version of the finite element solver for the time dependent generator coordinate method with the Gaussian overlap approximation

Science.gov (United States)

Regnier, D.; Dubray, N.; Verrière, M.; Schunck, N.

2018-04-01

The time-dependent generator coordinate method (TDGCM) is a powerful method to study the large amplitude collective motion of quantum many-body systems such as atomic nuclei. Under the Gaussian Overlap Approximation (GOA), the TDGCM leads to a local, time-dependent Schrödinger equation in a multi-dimensional collective space. In this paper, we present the version 2.0 of the code FELIX that solves the collective Schrödinger equation in a finite element basis. This new version features: (i) the ability to solve a generalized TDGCM+GOA equation with a metric term in the collective Hamiltonian, (ii) support for new kinds of finite elements and different types of quadrature to compute the discretized Hamiltonian and overlap matrices, (iii) the possibility to leverage the spectral element scheme, (iv) an explicit Krylov approximation of the time propagator for time integration instead of the implicit Crank-Nicolson method implemented in the first version, (v) an entirely redesigned workflow. We benchmark this release on an analytic problem as well as on realistic two-dimensional calculations of the low-energy fission of 240Pu and 256Fm. Low to moderate numerical precision calculations are most efficiently performed with simplex elements with a degree 2 polynomial basis. Higher precision calculations should instead use the spectral element method with a degree 4 polynomial basis. We emphasize that in a realistic calculation of fission mass distributions of 240Pu, FELIX-2.0 is about 20 times faster than its previous release (within a numerical precision of a few percents).

Infrared signatures of three molecular ions of relevance to the interstellar medium and planetary atmospheres have been detected at the Free Electron Laser for Infrared eXperiments, FELIX, at Radboud University (Nijmegen, The Netherlands) in combination with the 4K FELion 22-pole ion trap facility. Mid-infrared vibrational modes of protonated tricarbon monoxide, HC_3O^+, protonated vinyl cyanide, C_2H_3CNH^+, and protonated ethyl cyanide, C_2H_5CNH^+, were detected using resonant photodissociation of the respective Ne-complexes by monitoring the depletion of their cluster mass signal as a function of wavenumber. The infrared fingerprints compare very favorably with results from high-level quantum-chemical calculations performed at the CCSD(T) level of theory.

FCJ-121 Transversalising the Ecological Turn: Four Components of Felix Guattari’s Ecosophical Perspective

Directory of Open Access Journals (Sweden)

John Tinnell

2011-10-01

Full Text Available Many humanities scholars are working to transform their disciplines in response to new conditions and problems emerging in the twenty-first century. Arguably, two of the most important forces affecting contemporary global culture are the growing awareness of the ecological crisis and the proliferation of digital media. This essay endeavors to develop Felix Guattari’s “unfinished” concept of ecosophy into a theoretical framework for constructing productive syntheses between the ecological and the digital. In general, the essay first articulates ecosophical models of individual and collective subjectivity, and then argues that the best way to sustain ecosophical identity experience is to invent “post-media” practices, which harness the networked infrastructure of digital media such that specific pedagogical engagements with the technology effectively maximise the user’s capacity to affect and be affected by immanent forces in the world. In addition, this Guattarian rethinking of the ecological turn concurrently challenges the philosophical basis of the pedagogy of Nature appreciation that has characterised the eco-humanities landscape since the 1970s. The essay’s conclusions gesture toward a transversal eco-humanities, which would be rhizomatically rooted in Guattari’s preference for autopoiesis and becoming-other (via new media, rather than a static allegiance to the ideals of “Self-realisation” postulated by the deep ecology movement.

The Sao Felix Syenitic Massif (MSSF) has a tabular shape with about 32 km 2 that represents the south expression of the aligned syenitic plutonism, which occur in the middle part of Salvador-Curaca mobile belt (CMSC). Single zircon dating by stepwise Pb evaporation methodology yields an age of 2098 ± 1 Ma to SFSM. This data correlate the emplacement of the SFSM with the late stages of SCMB stabilization. This massif is isotopically characterized by negative epsilon neodymium values (-1.45 to -2.89) and low initial strontium ratio (0.701 to 0.704). SFSM isotopic signature is similar to the ones displayed by the others syenites from the belt and reflects an enriched source which should be related to a metasomatic enriched mantle. (author)

This work deals with a Rb/Sr geochronological study carried on granitoids and granulites of the Carajas Mineral Province (Rio Maria, Serra dos Gradaus and Serra do Pium regions) and Sao Felix do Xingu regions. The Manelao and Ourilandia granitoids of the Sao Felix do Xingu region are associated with the greenstone terrains of the Tucuma Group, and yield an age of 2749 ± 24 Ma with an initial ratio of 0.07028 ± 19, and 2677 ± 50 Ma with an initial ratio of 0.07016 ± 22, respectively. In the Rio Maria region, an age of 2541 ± 74 Ma with an initial ratio of 0.7104 ± 343 was obtained on the Mata Surrao Granite located near the Marajoara Village. This age confirms an archaean monzogranitic magmatism in this region. In the Gradaus area, the Cumaru Granodiorite give an mineral age of 2577 ± 27 Ma similar to the age obtained by whole rock method. Finally, Rb/Sr ages were obtained from granulitic rocks of the Pium Complex located at the Serra do Pium and near the Catete River. Samples of the Serra do Pium yielded ages of 2325 ± 71 Ma (whole rock) and 1857 ± 48 (minerals). Samples from the Catete River area give a whole rock age of 2018 ± 25 Ma with an initial ratio of 0.7039 ± 25. These data show that the Rb/Sr system in these granulitic rocks suffered changes during the Early Proterozoic times. The geochronological data here obtained confirm promptly an Archaean evolution in the studied regions, besides give rise the discussion about the problem related to the Transamazonian Event inside them.

Several Cliona species maintain intracellular populations of dinoflagellate zooxanthellae (i.e., Symbiodinium spp.), which also form symbioses with a variety of other invertebrates and protists (e.g., corals, molluscs, foraminifera). Unlike the case of coral symbioses, however, almost nothing is known of the metabolic interaction between sponges and their zooxanthella symbionts. To assess this interaction, we performed a tracer experiment to follow C and N in the system, performed a reciprocal transplant experiment, and measured the stable carbon isotope ratio of Cliona spp. with and without zooxanthellae to study the influence of environment on the interaction. We found strong evidence of a transfer of C from zooxanthellae to their sponge hosts but no evidence of a transfer of N from sponge to zooxanthellae. We also saw significant influences of the environment on the metabolism of the sponges. Finally, we observed significant differences in carbon metabolism of sponge species with and without symbionts. These data strongly support hypotheses of metabolic integration between zooxanthellae and their sponge host and extend our understanding of basic aspects of benthic-pelagic coupling in shallow-water marine environments.

Nava, Héctor; Carballo, José Luis

2008-09-01

Species richness (S) and frequency of invasion (IF) by boring sponges on living colonies of Pocillopora spp. from National Park Isla Isabel (México, East Pacific Ocean) are presented. Twelve species belonging to the genera Aka, Cliona, Pione, Thoosa and Spheciospongia were found, and 56% of coral colonies were invaded by boring sponges, with Cliona vermifera Hancock 1867 being the most abundant species (30%). Carbonate dissolution rate and sediment production were quantified for C. vermifera and Cliona flavifodina Rützler 1974. Both species exhibited similar rates of calcium carbonate (CaCO3) dissolution (1.2+/-0.4 and 0.5+/-0.2 kg CaCO3 m(-2) year(-1), respectively, mean +/- s.e.m.), and sediment production (3.3+/-0.6 and 4.6+/-0.5 kg CaCO3 m(-2) year(-1)), resulting in mean bioerosion rates of 4.5+/-0.9 and 5.1+/-0.5 kg CaCO3 m(-2) year(-1), respectively. These bioerosion rates are close to previous records of coral calcification per unit of area, suggesting that sponge bioerosion alone can promote disequilibrium in the reef accretion/destruction ratio in localities that are heavily invaded by boring sponges. The proportion of dissolved material by C. vermifera and C. flavifodina (27 and 10.2%, respectively) confirms that chemical bioerosion plays an important role in sponge bioerosion and in the CaCO3 cycle in coral reefs.

The FELIX collaboration has proposed the construction of a full acceptance detector for the LHC, to be located at Intersection Region 4, and to be commissioned concurrently with the LHC. The primary mission of FELIX is QCD: to provide comprehensive and definitive observations of a very broad range of strong-interaction processes. This paper reviews the detector concept and performance characteristics, the physics menu, and plans for integration of FELIX into the collider lattice and physical environment. The current status of the FELIX Letter of Intent is discussed

Sulfated Polysaccharides in Marine Sponges: Extraction Methods and Anti-HIV Activity

Directory of Open Access Journals (Sweden)

Ana I. S. Esteves

2011-01-01

Full Text Available The extraction, fractionation and HIV-1 inhibition potential of polysaccharides extracted from three species of marine sponges, Erylus discophorus, Cliona celata and Stelletta sp., collected in the Northeastern Atlantic, is presented in this work. The anti-HIV activity of 23 polysaccharide pellets and three crude extracts was tested. Crude extracts prepared from Erylus discophorus specimens were all highly active against HIV-1 (90 to 95% inhibition. Cliona celata pellets showed low polysaccharide content (bellow 38.5% and almost no anti-HIV activity (<10% inhibition. Stelletta sp. pellets, although quite rich in polysaccharide (up to 97.3%, showed only modest bioactivity (<36% HIV-1 inhibition. Erylus discophorus pellets were among the richest in terms of polysaccharide content (up to 98% and the most active against HIV-1 (up to 95% inhibition. Chromatographic fractionation of the polysaccharide pellet obtained from a specimen of Erylus discophorus (B161 yielded only modestly active fractions. However, we could infer that the active molecule is most probably a high molecular weight sulfated polysaccharide (>2000 kDa, whose mechanism is possibly preventing viral attachment and entry (fusion inhibitor.

Marine sponges (Porifera: Demospongiae) from the Gulf of México, new records and redescription of Erylus trisphaerus (de Laubenfels, 1953).

Marine sponges usually constitute the most diverse group of the benthic community in coral reefs. Although they are reasonably well studied at the northern Gulf of Mexico (GMx), the southern GMx is poorly known and lacks records from many major reef systems that lie off the Mexican coast. The present taxonomic study is the first sponge account from Alacranes reef, the largest coral reef system in the GMx, and from the shallow reef banks of Sisal, both in the northwest Yucatan Peninsula. The 19 species herein described represent the first sponge fauna records from these reefs. Among these, seven species represent new record for GMx: Erylus formosus, Cliona flavifodina, Spirastrella aff. mollis, Strongylacidon bermuda, Topsentia bahamensis, Agelas tubulata and Chelonaplysilla aff. erecta. Twelve species are new records for the Southern GMx: Erylus trisphaerus, Cliona amplicavata, Chondrilla caribensis, Halichondria lutea, Hymeniacidon caerulea, Axinella corrugata, Dragmacidon reticulatum, Chalinula molitba, Amphimedon caribica, A. complanata, Hyatella cavernosa and Dysidea variabilis. Additionally, a redescription of Erylus trisphaerus is presented which had not been reviewed since its original description in 1953 off Western Florida, except that it was listed for north La Habana, Cuba.

Simulating the effects of plasma disruption with a 1 MA current pulse in a coaxial test fixture

International Nuclear Information System (INIS)

Praeg, W.F.

1985-01-01

A test fixture for simulating plasma disruptions, comprising two coaxial cylinders, has been designed for use with Argonne's electromagnetic test facility FELIX. A pulsed power supply drives a half cycle sine wave current of 10 0 A through the test fixture generating fields of -1 . The coaxial structure is 140 cm long, has an outer cylinder with an OD of 78 cm and an inner cylinder with an OD of 8.3 cm. It is surrounded by the FELIX solenoid field of 1 T. This proposed upgrade of the FELIX facility should be useful for testing the effect of plasma disruption on First Wall-Blanket-Shield (FWBS) structures; a future upgrade of the solenoid field to 4 T will allow to simulate reactor conditions even better

A decadal analysis of bioeroding sponge cover on the inshore Great Barrier Reef.

2017-06-02

Decreasing coral cover on the Great Barrier Reef (GBR) may provide opportunities for rapid growth and expansion of other taxa. The bioeroding sponges Cliona spp. are strong competitors for space and may take advantage of coral bleaching, damage, and mortality. Benthic surveys of the inshore GBR (2005-2014) revealed that the percent cover of the most abundant bioeroding sponge species, Cliona orientalis, has not increased. However, considerable variation in C. orientalis cover, and change in cover over time, was evident between survey locations. We assessed whether biotic or environmental characteristics were associated with variation in C. orientalis distribution and abundance. The proportion of fine particles in the sediments was negatively associated with the presence-absence and the percent cover of C. orientalis, indicating that the sponge requires exposed habitat. The cover of corals and other sponges explained little variation in C. orientalis cover or distribution. The fastest increases in C. orientalis cover coincided with the lowest macroalgal cover and chlorophyll a concentration, highlighting the importance of macroalgal competition and local environmental conditions for this bioeroding sponge. Given the observed distribution and habitat preferences of C. orientalis, bioeroding sponges likely represent site-specific - rather than regional - threats to corals and reef accretion.

Lewis, R.A.; Xu, W.; Pellemans, H.P.M.; Langerak, C.J.G.M.

1999-01-01

Full text: Intense THz radiation emitted by FELIX (Free Electron Laser for Infrared eXperiments) induces both photovoltage and photocurrent signals in a high-mobility (μ = 2 x 10 6 cm 2 /V s), low-density (n e = 2 x 10 11 cm -2 ) GaAs/AlGaAs-based 2DEG. Within the ∼5 μs FELIX macropulse, there is a rapid response in the longitudinal voltage of a Hall-bar sample, reproducible between pulses. A large response continues well after the pulse; this long-time-scale behaviour varies between pulses if the current exceeds a critical value (which decreases with radiation intensity and magnetic field). Within the macropulse, the photovoltage varies with magnetic field, saturating at low field (<100 mT). The photocurrent shows a rapid, non-resonant response, evident at integral filling factors in both longitudinal and transverse data, and a slower, cyclotron resonant response, peaking at ∼390 μs after the FELIX pulse. No anisotropy in the resistivity under polarised radiation was found

Scrub typhus is one of the differential diagnoses for fever with thrombocytopenia. ARDS associated with Scrub typhus has high morbidity and mortality. To evaluate clinical features, lab values, and outcome in patients with scrub typhus and comparison in patients with or without ARDS. A prospective observational study was conducted on 109 patients with febrile illness and thrombocytopenia during a period of 12 months. All 109 patients were tested with both Immune-chromatography test and Weil felix test. Patients having either Immune-chromatography test/Weil felix test positive have been included and considered as scrub typhus positive whereas negative for both Immune-chromatography and Weil felix test were excluded. Clinical features, lab parameters, and outcome were evaluated in all patients with scrub typhus. Statistical analysis used in this study was T-test. Among 58 patients who were included (After exclusion of 51 patients among total of 109 patients) 34 patients had no ARDS and 24 patients had ARDS. The clinical feature like dyspnoea, cough, low blood pressure (MAPscrub typhus patients group with ARDS. The higher titers of Weil-felix can be correlated with more severe form of disease according to our observation. All 34 Scrub typhus patients without ARDS recovered completely. Among 24 Scrub typhus patients with ARDS, 22 patients recovered, and 2 patients died. Scrub typhus is an important differential diagnosis in a patients having fever with thrombocytopenia. Scrub typhus associated with ARDS has high morbidity and mortality. Early diagnosis and treatment with doxycycline can prevent the occurrence of ARDS.

A new approach to the solution of the vacuum magnetic problem in fusion machines

International Nuclear Information System (INIS)

Zabeo, L.; Piccolo, F.; Sartori, F.; Albanese, R.; Cenedese, A.

2006-01-01

The magnetic vacuum topology reconstruction using the magnetic measurements is essential in controlling and understanding plasmas produced by fusion machines. In a wide range of the cases, the instruments to approach the problem have been designed for a specific machine and to solve a specific plasma model. Recently a new approach has been used by developing new magnetic software called Felix. The adopted solution in the design allows the use of the software not only at JET but also at different machines by simply changing a configuration file. A database describing the tokamak in the magnetic point of view is used to provide different vacuum magnetic models (polynomial, moments, filamentary) that can be solved by Felix without any recompiling or testing. In order to reduce the analysis and debugging time the software has been designed with modularity and platform independence in mind. That results in a large portability and in particular it allows use of the same code both offline and in real-time. One of the main aspects of the tool is its capability to solve different plasma models of current distribution by changing its configuration file. In order to improve the plasma magnetic reconstruction in real time a set of models has been run using Felix. An improved polynomial based model compared with the one presently used and two models using current filaments have been tested and compared. The new system has also been improved the calculation of plasma magnetic parameters. Double null configurations smooth transitions, more accurate gap and strike-point calculations, detailed boundary reconstruction are now systematically available. Felix is presently running at JET in different real-time analysis and control systems that need vacuum magnetic topology such as control of the plasma shape, the wall protection system [F.Piccolo et al.'Upgrade of the protection system for the first wall at JET in the ITER Be and W tiles prespective' this conference], the magnetic

Clinical diagnosis of scrub typhus is often difficult because the symptoms are very similar to those of other febrile illness such as dengue, leptospirosis, malaria and other viral hemorrhagic fevers. Though better diagnostic tests are available for rickettsial diseases and scrub typhus elsewhere, the Weil-Felix test is still commonly used in India, mainly because microimmunofluorescence assays (M-IFA) were not available in India till recently and relevant staff had insufficient training. The present study was performed to investigate the performance of M-IFA, IgM ELISA, and Weil-Felix test on 546 non-repeated serum samples from subjects suspected of having scrub typhus. One hundred and forty-three of these 546 samples were positive by M-IFA; these cases were also confirmed clinically to have scrub typhus based on their dramatic responses to doxycycline therapy. IgM ELISA was positive in 122 of the 143 M-IFA positive cases and the Weil-Felix test in 96. Though the Weil-Felix test is a heterophile agglutination test, it was found in this study to have good specificity but far too little sensitivity to use as a routine diagnostic test. IgM ELISA can be a good substitute for M-IFA. Incorporation of multiple prototype antigens on M-IFA slides is likely one of the reasons for its superior performance. As newer and better diagnostic assays become available for scrub typhus diagnosis in developed countries, it will be imperative to also use such tests in other endemic countries to prevent over- or under-diagnosis of scrub typhus. © 2015 The Societies and Wiley Publishing Asia Pty Ltd.

Data-acquisition systems for high-energy physics experiments like the ATLAS experiment at the European particle-physics research institute CERN are used to record experimental physics data and are essential for the effective operation of an experiment. Located in underground facilities with limited space, power, cooling, and exposed to ionizing radiation and strong magnetic fields, data-acquisition systems have unique requirements and are challenging to design and build. Traditionally, these systems have been composed of custom-designed electronic components to be able to cope with the large data volumes that high-energy physics experiments generate and at the same time meet technological and environmental requirements. Custom-designed electronics is costly to develop,effortful to maintain and typically not very flexible. This thesis explores an alternative architecture for data-acquisition systems based on commercial off-the-shelf (COTS) components. A COTS-based data distribution device called FELIX that will be integrated in ATLAS is presented. The hardware and software implementation of this device is discussed, with a specific focus on performance, heterogenity of systems and traffic patterns. The COTS-based readout approach is evaluated in the context of the future requirements of the ATLAS experiment. The main contributions of the thesis are an analysis of the ATLAS data-acquisition system with a focus on the readout system, a software architecture for the main application on FELIX hosts, a performance analysis and tuning based on computer science methods for central FELIX software components with respect to the requirements of the ATLAS experiment, a network communication library with a high-level software interface to utilize high-performance computing network technology for the purpose of data-acquisition systems, and an evaluation and discussion of ATLAS data-acquisition using FELIX systems as a case study for COTS-based data-acquisition in high

In the upgrade of ATLAS experiment [1], the front-end electronics components are subjected to a large radiation background. Meanwhile high speed optical links are required for the data transmission between the on-detector and off-detector electronics. The GBT architecture and the Versatile Link (VL) project are designed by CERN to support the 4.8 Gbps line rate bidirectional high-speed data transmission which is called GBT link [2]. In the ATLAS upgrade, besides the link with on-detector, the GBT link is also used between different off-detector systems. The GBTX ASIC is designed for the on-detector front-end, correspondingly for the off-detector electronics, the GBT architecture is implemented in Field Programmable Gate Arrays (FPGA). CERN launches the GBT-FPGA project to provide examples in different types of FPGA [3]. In the ATLAS upgrade framework, the Front-End LInk eXchange (FELIX) system [4, 5] is used to interface the front-end electronics of several ATLAS subsystems. The GBT link is used between them, to transfer the detector data and the timing, trigger, control and monitoring information. The trigger signal distributed in the down-link from FELIX to the front-end requires a fixed and low latency. In this paper, several optimizations on the GBT-FPGA IP core are introduced, to achieve a lower fixed latency. For FELIX, a common firmware will be used to interface different front-ends with support of both GBT modes: the forward error correction mode and the wide mode. The modified GBT-FPGA core has the ability to switch between the GBT modes without FPGA reprogramming. The system clock distribution of the multi-channel FELIX firmware is also discussed in this paper.

The hardware and software implementation of this device is discussed, with a specific focus on performance, heterogenity of systems and traffic patterns. The COTS-based readout approach is evaluated in the context of the future requirements of the ATLAS experiment. The main contributions of the thesis are an analysis of the ATLAS data-acquisition system with a focus on the readout system, a software architecture for the main application on FELIX hosts, a performance analysis and tuning based on computer science methods for central FELIX software components with respect to the requirements of the ATLAS experiment, a network communication library with a high-level software interface to utilize high-performance computing network technology for the purpose of data-acquisition systems, and an evaluation and discussion of ATLAS data-acquisition using FELIX systems as a case study for COTS-based data-acquisition in high

Dielectric and electro-optical parameters of two ferroelectric liquid crystals: a comparative study

International Nuclear Information System (INIS)

Kumar Misra, Abhishek; Kumar Srivastava, Abhishek; Shukla, J P; Manohar, Rajiv

2008-01-01

Dielectric relaxation and an electro-optical study of two ferroelectric liquid crystals having different spontaneous polarizations (Felix 16/100 and Felix 17/000) showing SmC* and SmA phases have been performed in the temperature range 30-80 compfn C. The experimental data have been used to determine different relaxation parameters, viz. distribution parameter, relaxation frequency, dielectric strength and rotational viscosity. The Goldstone mode of dielectric permittivity has been well observed for both the samples under investigation. The activation energy of both the samples has also been determined by the best theoretical fitting of the Arrhenius plot. We have also evaluated the optical response time and anchoring energy coefficients from electro-optical measurement techniques for these samples.

Full Text Available Scrub typhus is an acute febrile illness that is known to be endemic in the South East Asian countries and the Western Pacific region. We here report an outbreak in the tiny Himalayan state of Sikkim. Patients with pyrexia of unknown origin were evaluated. They were screened by Weil-Felix test and the rapid immunochromatographic method. Samples that were positive by either Weil-Felix agglutination test or by rapid immunochromatography were confirmed by IgM enzyme-linked immunosorbent assay (ELISA. A total 204 samples were screened. Sixty-three patients were confirmed positive among which 42 were male and 21 were female. Effective management and early administration of antibiotics will help prevent the complications and mortality associated with scrub typhus.

Knippels, G.M.H.; Meer, A.F.G. van der

1998-01-01

The most recent upgrades and improvements to the free-electron laser (FEL) facility FELIX are presented. Special attention is paid to the improved beam-handling and diagnostic station. In this evacuated beam station a device is implemented that is capable of selecting single micropulses with measured efficiencies of more than 50% over the whole wavelength range of FELIX (5-110 μm). Furthermore, the broadband autocorrelator for micropulse length measurements and the planned continuous polarization rotator based on reflective optics are discussed. Recent additions to the ancillary equipment available to FEL users are presented briefly. The most important ones are the mirror-dispersion-controlled 10-fs Ti:sapphire laser and the 40-T magnet.

The author describes the situation related to the supply of the Community with nuclear fuels and to services going with the fuel cycle as well as international problems and the necessary objectives of the European Community for ensuring the nuclear fuel cycle in Europe. He recapitulates that during the past few years nuclear power policy has become diversiform and more complicated. The raw materials exporting countries have made demands which could not be accepted in this form by the import-dependent European countries. Tensions arising between friendly nations have to be solved. The European Community has to take the lead and take confidence-generating measures such as giving political guarantees and establishing a working inspection system. (HSCH) [de

Microscopic predictions of fission yields based on the time dependent GCM formalism

International Nuclear Information System (INIS)

Regnier, D.; Dubray, N.; Verriere, M.; Schunck, N.

2016-01-01

Accurate knowledge of fission fragment yields is an essential ingredient of numerous applications ranging from the formation of elements in the r-process to fuel cycle optimization in nuclear energy. The need for a predictive theory applicable where no data is available, together with the variety of potential applications, is an incentive to develop a fully microscopic approach to fission dynamics. One of the most promising theoretical frameworks is the time-dependent generator coordinate method (TDGCM) applied under the Gaussian overlap approximation (GOA). Previous studies reported promising results by numerically solving the TDGCM+GOA equation with a finite difference technique. However, the computational cost of this method makes it difficult to properly control numerical errors. In addition, it prevents one from performing calculations with more than two collective variables. To overcome these limitations, we have developed the new code FELIX-1.0 that solves the TDGCM+GOA equation based on the Galerkin finite element method. In this article, we briefly illustrate the capabilities of the solver FELIX-1.0, in particular its validation for n+ 239 Pu low energy induced fission. FELIX-1.0 gives full control on the numerical precision of fission product yields in neutron-induced fission, and its scalability also enables series of dynamical calculations on several potential energy surfaces. Preliminary results suggest an important sensitivity of our two-dimensional approach to the input potential energy surface

A computer code for processing of data from neutron activation analysis is described. The code is capable of qualitative and quantitative analysis of regular spectra from neutron irradiated samples, measured by a Ge(li) detector. Multichannel analysers with 1024 channels, such as TN 1705 or a Romanian made MCA 79, and an ITC interface can be used. The code is implemented on FELIX M118 and FELIX M216 microcomputers. Spectrum processing is performed off line, after storing the data on a floppy disk. The background is assumed to be a polynomial of first, second or third degree. Qualitative analysis is performed by recursive least square, Gaussian curve fitting. The elements are identified using a polynomial relation between energy and channel, obtained by calibration with a standard sample

Microarray Glycan Profiling Reveals Algal Fucoidan Epitopes in Diverse Marine Metazoans

Directory of Open Access Journals (Sweden)

Armando A. Salmeán

2017-09-01

Full Text Available Despite the biological importance and pharmacological potential of glycans from marine organisms, there are many unanswered questions regarding their distribution, function, and evolution. Here we describe microarray-based glycan profiling of a diverse selection of marine animals using antibodies raised against fucoidan isolated from a brown alga. We demonstrate the presence of two fucoidan epitopes in six animals belonging to three phyla including Porifera, Molusca, and Chordata. We studied the spatial distribution of these epitopes in Cliona celata (“boring sponge” and identified their restricted localization on the surface of internal chambers. Our results show the potential of high-throughput screening and probes commonly used in plant and algal cell wall biology to study the diversity and distribution of glycan structures in metazoans.

Real-Time, Single-Shot Temporal Measurements of Short Electron Bunches, Terahertz CSR and FEL Radiation

CERN Document Server

Berden, G; Van der Meer, A F G

2005-01-01

Electro-optic detection of the Coulomb field of electron bunches is a promising technique for single-shot measurements of the bunch length and shape in the sub-picosecond time domain. This technique has been applied to the measurement of 50 MeV electron bunches in the FELIX free electron laser, showing the longitudinal profile of single bunches of around 650 fs FWHM [Phys. Rev. Lett. 93, 114802 (2004)]. The method is non-destructive and real-time, and therefore ideal for online monitoring of the longitudinal shape of single electron bunches. At FELIX we have used it for real-time optimization of sub-picosecond electron bunches. Electro-optic detection has also been used to measure the electric field profiles of far-infrared (or terahertz) optical pulses generated by the relativistic electrons. We have characterised the far-infrared output of the free electron laser, and more recently, we have measured the temporal profile of terahertz optical pulses generated at one of the bending magnets.

Generation of frequency-chirped optical pulses with felix

Energy Technology Data Exchange (ETDEWEB)

Knippels, G.M.H.; Meer, A.F.G. van der; Mols, R.F.X.A.M. [FOM-Institute for Plasma Physics, Nieuwegein (Netherlands)] [and others

1995-12-31

Frequency-chirped optical pulses have been produced in the picosecond regime by varying the energy of the electron beam on a microsecond time scale. These pulses were then compressed close to their bandwidth limit by an external pulse compressor. The amount of chirp can be controlled by varying the sweep rate on the electron beam energy and by cavity desynchronisation. To examine the generated chirp we used the following diagnostics: a pulse compressor, a crossed beam autocorrelator, a multichannel electron spectrometer and multichannel optical spectrometer. The compressor is build entirely using reflective optics to permit broad band operation. The autocorrelator is currently operating from 6 {mu}m to 30 {mu}m with one single crystal. It has been used to measure pulses as short as 500 fs. All diagnostics are evacuated to prevent pulse shape distortion or pulse lengthening caused by absorption in ambient water vapour. Pulse length measurements and optical spectra will be presented for different electron beam sweep rates, showing the presence of a frequency chirp. Results on the compression of the optical pulses to their bandwidth limit are given for different electron sweep rates. More experimental results showing the dependence of the amount of chirp on cavity desynchronisation will be presented.

Felix Vicq d'Azyr: anatomy, medicine and revolution.

Science.gov (United States)

Parent, André

2007-02-01

Félix Vicq d'Azyr was born in 1748 in the small town of Valognes, Normandy. He studied medicine in Paris but he was particularly impressed by the lectures given at the Jardin du Roi by the comparative anatomist Louis Daubenton and the surgeon Antoine Petit. In 1773, Vicq d'Azyr initiated a series of successful lectures on human and animal anatomy at the Paris Medical School, from which he received his medical degree in 1774. He was elected the same year at the Academy of Sciences at age 26, thanks to his outstanding contributions to comparative anatomy. Vicq d'Azyr became widely known after his successful management of a severe cattle plague that occurred in the southern part of France in 1774, an event that led to the foundation of the Royal Society of Medicine in 1778. As Permanent Secretary of this society, Vicq d'Azyr wrote several eulogies that were models of eloquence and erudition and worth him a seat at the French Academy in 1788. Vicq d'Azyr published in 1786 a remarkable anatomy and physiology treatise: a large in-folio that contained original descriptions illustrated by means of nature-sized, colored, human brain figures of a quality and exactitude never attained before. In 1789, Vicq d'Azyr was appointed physician to the Queen Marie-Antoinette and, in 1790, he presented to the Constituent Assembly a decisive plan to reform the teaching of medicine in France. Unfortunately, Vicq d'Azyr did not survive the turmoil of the French Revolution; he died at age 46 on June 20, 1794.

Experimental modeling of eddy currents and deflections for tokamak limiters

International Nuclear Information System (INIS)

Hua, T.Q.; Knott, M.J.; Turner, L.R.; Wehrle, R.B.

1986-01-01

In this study, experiments were performed to investigate deflection, current, and material stress in cantilever beams with the Fusion ELectromagnetic Induction eXperiment (FELIX) at the Argonne National Laboratory. Since structures near the plasma are typically cantilevered, the beams provide a good model for the limiter blades of a tokamak fusion reactor. The test pieces were copper, aluminum, phosphor bronze, and brass cantilever beams, clamped rigidly at one end with a nonconducting support frame inside the FELIX test volume. The primary data recorded as functions of time were the beam deflection measured with a noncontact electro-optical device, the total eddy current measured with a Rogowski coil and linking through a central hole in the beam, and the material stress extracted from strain gauges. Measurements of stress and deflection were taken at selected positions along the beam. The extent of the coupling effect depends on several factors. These include the size, the electrical and mechanical properties of the beam, segmenting of the beam, the decay rate of the dipole field, and the strength of the solenoid field

The role of burrowing sponges in bioerosion.

Science.gov (United States)

Rützler, Klaus

1975-09-01

Among the large number of limestone-eroding organisms, sponges, mainly of the family Clinonidae are of special interest because of their efficient means of substratum penetration by cellular etching and because they release characteristically shaped calcium carbonate chips which can be detected in the mud-size fraction of many sediments. Identifiable trace fossils and sediments are of great ecological and paleoecological significance.As new data on the excavating mechanism have become available, the questions of burrowing rates and sediment production have gained importance. Extrapolation from shortterm experiments (under 6 months) on substrate invasion are inconclusive because of high initial penetration rates resulting from mechanical stimulation and lack of competition. New experiments show that the rate curve flattens after 6 months and that optimum longterm erosion of CaCO 3 does not exceed 700 mg m -2 year -1 (Cliona lampa and C. aprica). Substrate limitations and competition will further reduce this rate.By monitoring the production of CaCO 3 chips by Cliona lampa, it was possible to link activity patterns to certain environmental factors. Mechanical stimuli, high light intensity, strong currents and, possibly, low temperature seem to accelerate the burrowing process. Sponge-generated chips can make up over 40% of coral mud when deposited in the current shadow of the reef framework.Using transect counts and sponge area-biomass conversion factors, the mean abundance of burrowing sponges on the Bermuda platform could be calculated. On suitable hard bottom substrates it averages 16 g dry weight per m 2 . From this value the burrowing potential of sponges can be estimated as 256 g CaCO 3 per m 2 substrate per year. Since 97-98% of the eroded limestone remains in particulate form, the contribution of fine sediments can amount to 250 g m -2 year -1 .Attention is called to the fact that erosion rates by burrowers can not directly be compared with those of borers or

Microscopic predictions of fission yields based on the time dependent GCM formalism

Science.gov (United States)

Regnier, D.; Dubray, N.; Schunck, N.; Verrière, M.

2016-03-01

Accurate knowledge of fission fragment yields is an essential ingredient of numerous applications ranging from the formation of elements in the r-process to fuel cycle optimization in nuclear energy. The need for a predictive theory applicable where no data is available, together with the variety of potential applications, is an incentive to develop a fully microscopic approach to fission dynamics. One of the most promising theoretical frameworks is the time-dependent generator coordinate method (TDGCM) applied under the Gaussian overlap approximation (GOA). Previous studies reported promising results by numerically solving the TDGCM+GOA equation with a finite difference technique. However, the computational cost of this method makes it difficult to properly control numerical errors. In addition, it prevents one from performing calculations with more than two collective variables. To overcome these limitations, we developed the new code FELIX-1.0 that solves the TDGCM+GOA equation based on the Galerkin finite element method. In this article, we briefly illustrate the capabilities of the solver FELIX-1.0, in particular its validation for n+239Pu low energy induced fission. This work is the result of a collaboration between CEA,DAM,DIF and LLNL on nuclear fission theory.

Neutrino oscillations: An essay in honor of Felix Boehm

International Nuclear Information System (INIS)

Rosen, S.P.

1989-01-01

We briefly review the theory of neutrino oscillations and the MSW effect and report on new calculations by Rosen and Gelb for solar neutrino-electron scattering. The aim of these calculations is to try to use the scattering process as a means of choosing between the three types of MSW solutions for the 37 Cl experiment. Both the efficiency and the resolution of the Kamiokande II detector are taken into account and the ratio R of the MSW prediction to the standard solar model prediction is calculated for different cuts on the minimum electron energy. We find that the adiabatic solution requires R to be less than 1/3, the large angle one requires it to be less than 2/3, and the nonadiabatic one restricts it to a value close to 1/2. The central value of the published KII data is close to 1/2, but the errors are too large to exclude the other solutions. 20 refs., 1 fig

Bleaching and recovery of a phototrophic bioeroding sponge

Science.gov (United States)

Marlow, Joseph; Davy, Simon K.; Shaffer, Megan; Haris, Abdul; Bell, James J.

2018-06-01

In the Wakatobi region of Indonesia, a prolonged period of elevated water temperature in 2016 caused extensive coral bleaching and mortality. Unusually, bleaching was also observed in the bioeroding sponge Cliona aff. viridis, with affected sponges expelling 99% of their Symbiodinium. Bleaching surveys of C. aff. viridis were conducted 6 weeks apart, coinciding with a 0.8 °C drop in water temperature. Over this period, bleaching prevalence dropped from 73.9% (± 9.9 SE) to 25.7% (± 5.8 SE), and bleaching severity dropped from 25.95% (± 4.5 SE) to 11.54% (± 1.9 SE) of sponge tissue. Over the same period, monitored bleached sponges showed an 81% drop in bleaching severity, but also a 13% reduction in overall sponge size. Our results show that while the clionaid- Symbiodinium relationship is susceptible to break down under thermal stress, rapid recovery can occur, although incurring some partial host mortality.

Felix Hoppe-Seyler Lecture 1997. Protective antibody responses against viruses.

Science.gov (United States)

Zinkernagel, R M

1997-08-01

Neutralizing antibody responses against the acute cytopathic vesicular stomatitis virus (VSV) have been studied in mice to evaluate their general characteristics including specificity, self-/non-self discrimination and memory. IgM responses are generated very early, by day 3 to 4, in a T helper cell-independent fashion and without VSV having polyclonal activating capacities. The order of the glycoprotein tips on the virus envelope (multiple, 8-10 nm distance, paracrystalline) exhibiting the neutralizing determinants are key to this prompt response. These paracrystalline identical multimeric antigens are characteristic of infectious agents and are always reacted against by B cells. Self-antigens that are accessible to B cells in the intact host are either monomeric in serum or mobile multimers on cell surfaces; these configurations need contact dependent or contact independent T help, respectively. Because T help is tolerant against self-antigens, no anti-self B cell responses are usually induced against monomeric self-antigens. If collagen or DNA (rigid multimeric self-antigens) become accessible, however, they may become targets of auto-antibody responses. The antibody repertoire against VSV is partially contained in the germline and partially is generated by somatic mutation; they seem not to undergo affinity-maturation. In any case protection against lethal infection is dependent upon strictly T helper cell dependent IgG generated by day 6 to 7 and reaches a protective level of about 1-10 micrograms/ml. Interesting affinity/avidity and onrate above a minimal threshold are of no apparent advantage for protection in vivo. Maintenance of these antibody levels by antigen depots, and not the presence of memory B cells alone, is key to providing protective immunological memory. Collectively these data suggest that studying biologically important protective antibody responses may modify some of the parameters that have been defined by studying hapten specific antibody responses.

Coupling between eddy currents and rigid body rotation: analysis, computation, and experiments

International Nuclear Information System (INIS)

Hua, T.Q.; Turner, L.R.

1985-01-01

Computation and experiment show that the coupling between eddy currents and the angular deflections resulting from those eddy currents can reduce electromagnetic effects such as forces, torques, and power dissipation to levels far less severe than would be predicted without regard for the coupling. This paper explores the coupling effects beyond the parameter range that has been explored experimentally, using analytical means and the eddy-current computer code EDDYNET. The paper also describes upcoming FELIX experiments with cantilevered beams

Various methods are available for the evaluation of skin color. A skin color scale chart is a convenient and inexpensive tool. However, the correlation between a skin color scale chart and objective measurement has not been evaluated. To assess the correlation between skin color evaluation done by a skin color scale chart (Felix von Luschan skin color chart) and a narrowband reflectance spectrophotometer (Mexameter MX18). The participants were evaluated for skin color by using the Felix von Luschan skin color chart (range 1-36) and a narrowband reflectance spectrophotometer (Mexameter MX18) in which the results of the measurements were expressed as Erythema (E) and Melanin (M) indices. Skin color was measured on four different anatomical skin sites from each participant on the medial aspect of the volar and the dorsal regions of both forearms. A total of 208 records from 52 participants were established. The majority of participants (19.2%) were rated with the skin color scale at the number 16 (range 14-33). The mean M plus E, M, and E indices were 498.9 ± 143.9, 230.4 ± 74.4, and 268.5 ± 73.2, respectively. The correlation coefficient between the number on the skin color scale and each index: M plus E, M, and E indices were 0.90, 0.90, and 0.86, respectively, with a statistical significance of P spectrophotometer.

Macrobioerosion in Porites corals in subtropical northern South China Sea: a limiting factor for high-latitude reef framework development

Chen, Tianran; Li, Shu; Yu, Kefu

2013-03-01

Bioerosion is an important limiting factor in carbonate accretion and reef framework development; however, few studies have quantified the direct impact of macroborers on high-latitude coral communities, which are viewed as potential refuge during a period of global warming. In this study, internal macrobioerosion of Porites corals was examined at Daya Bay, subtropical northern South China Sea. The principal borers were the bivalve Lithophaga spp. and the sponges Cliona spp. and Cliothosa spp. (≥80 %), while sipunculid and polychaete worms and barnacles accounted for small amounts of bioerosion (≤20 %). Porites corals were heavily bioeroded in areas impacted by aquacultural and urban activities (10.34-27.55 %) compared with corals in relatively unpolluted areas (2.18-6.76 %). High levels of bioerosion, especially boring bivalve infestation, significantly weaken the corals and increase their susceptibility to dislodgement and fragmentation in typhoons, limiting accumulation of limestone framework. This study implies that carbonate accretion and reef development for high-latitude coral communities may be limited in future high-CO2 and eutrophication-stressed environments.

FELs, nice toys or efficient tools?

CERN Document Server

Van der Meer, Alex F G

2004-01-01

An FEL is an intrinsically interesting device and pushing its performance presents a natural challenge to a physicist. Nonetheless, the main justification for doing FEL research is of course its potential as a unique, versatile source of radiation to be employed for something useful. After 25 years of FEL research, one may wonder how efficient these tools have become. In this paper, I will reflect on this issue from the perspective of 10 years of operation of FELIX as a user facility.

Encapsulation Strategies of Bacteriophage (Felix O1) for Oral Therapeutic Application.

Science.gov (United States)

Islam, Golam S; Wang, Qi; Sabour, Parviz M

2018-01-01

Due to emerging antibiotic-resistant strains among the pathogens, a variety of strategies, including therapeutic application of bacteriophages, have been suggested as a possible alternative to antibiotics in food animal production. As pathogen-specific biocontrol agents, bacteriophages are being studied intensively. Primarily their applications in the food industry and animal production have been recognized in the USA and Europe, for pathogens including Salmonella, Campylobacter, Escherichia coli, and Listeria. However, the viability of orally administered phage may rapidly reduce under the harsh acidic conditions of the stomach, presence of enzymes and bile. It is evident that bacteriophages, intended for phage therapy by oral administration, require efficient protection from the acidic environment of the stomach and should remain active in the animal's gastrointestinal tract where pathogen colonizes. Encapsulation of phages by spray drying or extrusion methods can protect phages from the simulated hostile gut conditions and help controlled release of phages to the digestive system when appropriate formulation strategy is implemented.

Electromagnetic analysis for fusion reactors: status and needs

International Nuclear Information System (INIS)

Turner, L.R.

1983-01-01

Electromagnetic effects have far-reaching implications for the design, operation, and maintenance of future fusion reactors. Two-dimensional (2-D) eddy current computer codes are available, but are of limited value in analyzing reactors. Three-dimensional (3-D) codes are needed, but are only beginning to be developed. Both 2-D and 3-D codes need verification against experimental data, such as that provided by the upcoming FELIX experiments. Coupling between eddy currents and deflections has application in fusion reactor design and is being studied both by analysis and experiment

The Gravestone of Felipe II in «El amante agradecido», by Lope de Vega: a Historical Image.

2013-05-01

Full Text Available  Felix Lope de Vega, in his play El Amante agradecido (ca. 1602, writes a praise to Felipe II, after the death of the king in 1598. The praise, almost three hundred lines dedicated to the gravestone that the city of Seville built in honour of Felipe II, does not really belong with the main purpose of the play: an urban comedy with a lot of picaresque components. This article focuses on why the writer included that sort of eulogy and studies the different sources of the fragment. 

InGaAs/InAlAs superlattice detector for THz radiation

CERN Document Server

Schomburg, E; Kratschmer, M; Vollnhals, A; Scheuerer, R; Renk, K F; Ustinov, V; Zhukov, A; Kovsh, A

2002-01-01

We report the use of an InGaAs/InAlAs superlattice for detection of THz radiation pulses generated by a free-electron-laser (FELIX). The detector showed a response corresponding to a reduction of the direct current through the superlattice. The current reduction is attributed to the THz-field induced modulation of Bloch oscillations performed by miniband electrons. The detector response was measured in a frequency range between 4 and 12 THz and showed strong minima at the frequencies of infrared active transverse optic phonons. (10 refs).

Analytical Plan for Roman Glasses

Energy Technology Data Exchange (ETDEWEB)

Strachan, Denis M.; Buck, Edgar C.; Mueller, Karl T.; Schwantes, Jon M.; Olszta, Matthew J.; Thevuthasan, Suntharampillai; Heeren, Ronald M.

2011-01-01

Roman glasses that have been in the sea or underground for about 1800 years can serve as the independent “experiment” that is needed for validation of codes and models that are used in performance assessment. Two sets of Roman-era glasses have been obtained for this purpose. One set comes from the sunken vessel the Iulia Felix; the second from recently excavated glasses from a Roman villa in Aquileia, Italy. The specimens contain glass artifacts and attached sediment or soil. In the case of the Iulia Felix glasses quite a lot of analytical work has been completed at the University of Padova, but from an archaeological perspective. The glasses from Aquileia have not been so carefully analyzed, but they are similar to other Roman glasses. Both glass and sediment or soil need to be analyzed and are the subject of this analytical plan. The glasses need to be analyzed with the goal of validating the model used to describe glass dissolution. The sediment and soil need to be analyzed to determine the profile of elements released from the glass. This latter need represents a significant analytical challenge because of the trace quantities that need to be analyzed. Both pieces of information will yield important information useful in the validation of the glass dissolution model and the chemical transport code(s) used to determine the migration of elements once released from the glass. In this plan, we outline the analytical techniques that should be useful in obtaining the needed information and suggest a useful starting point for this analytical effort.

Comparison of optical and electron spectra in an infra-red free electron laser

Time-resolved electron and optical spectra recently acquired at the FELIX facility are presented, showing the evolution of the respective macropulses. A comparison is made between the optical power output during the macropulse and the measured power extracted from the electron beam using a simple model of the cavity losses. Data are available for a wide range of operating conditions: the wavelength range is from 9 {mu}m to 28 {mu}m and detuning are between 1/4{lambda} and 2{lambda}. The effect of rapid electron beam energy changes on the optical and electron spectra will also be discussed.

The Metaphysics of Morris R. Cohen: From Realism to Objective Relativism.

Science.gov (United States)

Cahoone, Lawrence

2017-01-01

Morris Cohen is mainly remembered as a philosopher of history and law, a friend of jurists (Oliver Wendell Holmes, Felix Frankfurter), and a teacher of more prominent philosophers (e.g., Ernest Nagel, Paul Weiss, Morton White). But his unique position as a student of the work of Russell and Peirce led him to make a distinctive contribution to the debate over realism in in the 1910s. Largely ignored and completely uncited, his early papers formulated what would later be called "objective relativism," influencing the later work of Columbia naturalism, hence American philosophy, from the 1940s to the 1960s.

2008-12-01

The development of entomology and medical entomology in France is discussed in the context of the prevalence of Lamarckian ideas concerning heredity and evolution. Lamarckian ideas have greatly influenced research carried out at the Institut Pasteur by Emile Roubaud and more generally in Felix Mesnil's laboratory, as well as research in general entomology at the Museum national d'histoire naturelle. By contrast, it did not influence research and teaching at the Faculté de médecine of Paris or that of physicians more generally including those in overseas Instituts Pasteur, which clearly kept away from theoretical discussion concerning the origin of variations and adaptation in insects of medical interest.

FCJ-149 Affect and Care in Intimate Transactions

Directory of Open Access Journals (Sweden)

Lone Bertelsen

2012-01-01

Full Text Available This article considers the ‘co-affective’ power of the new media artwork Intimate Transactions. This co-affective power operates at the ‘trans-subjective’ level of experience. In order to explore this level of experience the article draws on the work of Brian Massumi, Bracha Ettinger and Felix Guattari amongst others. For these thinkers the ‘trans-subjective’ level of experience, precisely because it is ‘co-affective’, holds ethical potential. The article argues for the importance of tending to ‘co-affective’ level of experience – both in designing “interactive” art, such as Intimate Transactions, and in life more generally.

1992-01-01

A program package ASYS for analysis of nonlinear algebraic equations based on the Groebner basis technique is described. The package is written in REDUCE computer algebra language. It has special facilities to treat polynomial ideals of positive dimension, corresponding to algebraic systems with infinitely many solutions. Such systems can be transformed to an equivalent set of subsystems with reduced number of variables in completely automatic way. It often allows to construct the explicit form of a solution set in many problems of practical importance. Some examples and results of comparison with the standard Reduce package GROEBNER and special-purpose systems FELIX and A1PI are given. 21 refs.; 2 tabs

Effects of combined dredging-related stressors on sponges: a laboratory approach using realistic scenarios.

Science.gov (United States)

Pineda, Mari-Carmen; Strehlow, Brian; Kamp, Jasmine; Duckworth, Alan; Jones, Ross; Webster, Nicole S

2017-07-12

Dredging can cause increased suspended sediment concentrations (SSCs), light attenuation and sedimentation in marine communities. In order to determine the combined effects of dredging-related pressures on adult sponges, three species spanning different nutritional modes and morphologies were exposed to 5 treatment levels representing realistic dredging scenarios. Most sponges survived under low to moderate turbidity scenarios (SSCs of ≤ 33 mg L -1 , and a daily light integral of ≥0.5 mol photons m -2 d -1 ) for up to 28 d. However, under the highest turbidity scenario (76 mg L -1 , 0.1 mol photons m -2 d -1 ) there was 20% and 90% mortality of the phototrophic sponges Cliona orientalis and Carteriospongia foliascens respectively, and tissue regression in the heterotrophic Ianthella basta. All three sponge species exhibited mechanisms to effectively tolerate dredging-related pressures in the short term (e.g. oscula closure, mucus production and tissue regression), although reduced lipids and deterioration of sponge health suggest that longer term exposure to similar conditions is likely to result in higher mortality. These results suggest that the combination of high SSCs and low light availability can accelerate mortality, increasing the probability of biological effects, although there is considerable interspecies variability in how adult sponges respond to dredging pressures.

Scrub typhus infection presenting as acute heart failure: A case report and systematic review of literature of cardiopulmonary involvement in scrub typhus infection

Directory of Open Access Journals (Sweden)

Animesh Ray

2016-01-01

Full Text Available We describe a middle aged previoulsy healthy female patient who presented with clinical features suggestive of acute heart failure. Investigations revealed very high NT pro-BNP, right heart enlargement, bilateral pulmonary alveolar edema and bilateral pleural effusion. In view of falling platelet counts and exudative pleural effusion inflammatory/infective causes were considered. Her Weil Felix test was strongly positive and IgM for scrub typhus also returned positive. She was started on doxycycline to which there was dramatic improvement. Thus in this case scrub typhus infection presented as acute right heart failure and the cause seemed elusive at the outset.We also systematically reviewed the existing literature on cardio-pulmonary manifestations of scrub typhus infection.

Personal correspondence written by Prof. Felix Krueger from Argentina in 1906-1907 to his teacher and mentor Wilhelm Wundt in Leipzig is situated in the historical context of the theoretical debates taking place at the University of Buenos Aires at the beginning of the 20th century. A critical survey of the transatlantic migration of psychological theories and their reception in Argentina raises the broader issues of the nature of the cultural and social roots of local interpretations induced by the circulation of theories across national fields of scientific inquiry. It is argued that national intellectual fields and the historicity of their categories of interpretation mediate in the foreign trade of theories.

"German Culture is where I am": Thomas Mann in Exile

Directory of Open Access Journals (Sweden)

Helmut Koopmann

1982-09-01

Full Text Available Thomas Mann in exile reacted like many writers expelled from Germany: totally irritated he tried to defend his own identity by claiming that he was still the leading representative of Germany. But about 1938 a process of dissociation from Germany started which led to sharp remarks on Germany in his The Beloved Returns , to his conviction that German culture was where he lived and to the acknowledgement of America as his new home. Traces of his experience of exile, and a late answer on his separation from Germany in 1933, however, are to be found even in his incompleted novel Felix Krull which seems to have turned the disgusting experience of exile into friendly mythological light.

The fragment of the 1-methylpyrene cation, 17C 11H+, is expected to exist in two isomeric forms, 1-pyrenemethylium PyrCH2+ and the tropylium containing species PyrC7+. We measured the infrared (IR) action spectrum of cold 17C 11H+ tagged with Ne using a cryogenic ion trap instrument coupled to the FELIX laser. Comparison of the experimental data with density functional theory calculations allows us to identify the PyrCH2+ isomer in our experiments. The IR Multi-Photon Dissociation spectrum was also recorded following the C2H2 loss channel. Its analysis suggests combined effects of anharmonicity and isomerisation while heating the trapped ions, as shown by molecular dynamics simulations.

Analysis of presence / absence records from two comparable megabenthic surveys of scallop grounds in the Bay of Fundy, Canada, in 1966-67 and 1997 showed profound change over three decades. There were no indications that any species were lost and the average number of taxa per station remained steady. However, spatial heterogeneities in the community were reduced and species composition changed significantly. Some taxa widespread in 1966-67 declined while others expanded, with frequencies of occurrence of individual taxa changing by up to 71%. The whelks Buccinum undatum and Colus spp., the bivalves Astarte spp. and Cyclocardia borealis, the toad crabs Hyas spp., the sea urchin Strongylocentrotus droebachiensis and the brittle stars (Ophiurida) showed particular increases. Corresponding declines were seen in the boring sponges Cliona spp., the horse mussel Modiolus modiolus, the scallop Chlamys islandica, the fan worm Pseudopotamilla reniformis and the stalked tunicate Boltenia ovifera. Replacement of attached, fragile, epifaunal, filter-feeding taxa by a combination of motile scavengers, motile filter-feeders and robust, burrowing filter-feeders suggests that the primary cause of the temporal change was physical impacts by fishing gear, even though trawling and scallop dragging in the area were neither intense nor new developments. Secondary causes of change may have included other ecosystem effects of fishing (supply of discards and bait), a mass mortality of scallops and a range expansion of a bryozoan ( Flustra foliacea).

Ancient Topometry, the Tracing of Towns in the Roman Epoch: Ulpia Traiana Dacica Sarmizegetusa - Romania. Second Part

2015-05-01

While following the rituals and the ancient topometrical methods used by the Romans in tracing cities according to the Etruscan tradition, this paper presents the historical, anthropological and archaeological aspects, analyzing techniques being used and aims at determining the day when there was inaugurated after the 2nd Dacian-Roman war, 105-106 AD, the new capital, Colonia Ulpia Traiana Augusta Dacica Sarmizegetusa, of the new province of Roman Empire, "Dacia Felix". The aspects of the problem which require a special archaeoastronomical and archaeometrical analysis are the physical horizon and the sun's movement. The provisional results obtained so far lead to the conclusion that the capital might have been traced in the 15-18 september period, that coincided with Emperor Trajan's birthday.

Art and Androgyny: The Aerialist

Directory of Open Access Journals (Sweden)

Naomi Ritter

1989-08-01

Full Text Available Among the many circus performers who have fascinated writers and artists since Romanticism, the clown and the aerialist predominate. In the nineteenth century, the tightrope artiste inspired comparisons with the (self-styled equally daring and equally craftsmanlike poet. The vertical metaphor suggested a vision of transcendent art that Romantics and their heirs claimed for themselves. In the twentieth century, vestiges of the same identification and transcendence remain, but a new sexual focus appears also. Two important texts by Cocteau and Thomas Mann, "Le Numero de Barbette" (1926 and Chapter 1 in Book III of Felix Krull ( 1951, show the aerial artiste as sexually ambivalent. An intertextual discussion of these two works highlights unnoted similarities in the seemingly opposed aesthetics of the two writers.

Human cases of scrub typhus are reported every year from Puducherry and adjoining areas in southern India. However, information on the presence of causative agent, Orientia tsutsugamushi, and its vectors is lacking. Hence, the objective of the study was to find out the vector as well as pathogen distribution in rodents and shrews present in the scrub typhus-reported areas in southern India. Trombiculid mites were collected by combing rats and shrews collected using Sherman traps and identified to species level following standard taxonomical keys. The serum samples of the animals were used for Weil-Felix test and the clots containing blood cells were used for DNA extraction and polymerase chain reaction (PCR). A total of 181 animals comprising four rodent species and one shrew species were collected from 12 villages. High proportion of chiggers was collected from the shrew, Suncus murinus (79.1%) and Rattus rattus (47.6%). A total of 10,491 trombiculid mites belonging to nine species were collected. Leptotrombidium deliense, the known vector of scrub typhus pathogen, was the predominant species (71.0%) and the chigger (L. deliense) index was 41.1 per animal. Of the 50 animals screened for the pathogen, 28 showed agglutination against OX-K in Weil-Felix test indicating the presence of antibodies against O. tsutsugamushi, the causative agent of scrub typhus. PCR carried out with the DNA extracted from blood samples of two of the animals were positive for GroEl gene of O. tsutsugamushi. L. deliense index was well above the critical limit of chigger load, indicating that all the villages were receptive for high risk of transmission of scrub typhus to human. Pathogen positivity was higher among animals collected from villages recorded for higher chigger indices due to active transmission between the chigger mites and reservoir host animals. The results are suggestive of routine vector/pathogen surveillance at hot spots to initiate timely preventive measures.

An immunocompetent 5 year-old girl presented with pyrexia of unknown origin associated with headache. Initial investigations showed leukocytosis and an increased erythrocyte sedimentation rate. A Widal-Weil Felix test, blood film for malarial parasites, mycoplasma IgM antibody, cultures from blood and urine, full blood picture, Mantoux test, and chest x-ray were all negative. A lumbar puncture was done as part of a work-up for pyrexia of unknown origin. Cryptococcus neoformans was seen on India ink examination and confirmed on culture. She was treated with 10 weeks of intravenous amphotericin B and 8 weeks of fluconazole. Further immunological tests did not reveal any defect in the cell-mediated immune system. C. neoformans meningitis may present with non-specific symptoms and should be considered in a work-up for pyrexia of unknown origin.

As regards sensitivity to ultraviolet radiation, the morphological mutant S. typhimurium LT2 WT ED 143 is similar to the ion-mutants E. coli K12. Data are presented on the sensitivity of the mutant and initial strains to ultraviolet radiation at various phases of growth, on the capacity for restoring the bacteriophages P22 and Felix O after irradiation and on the influence of various treatments after ultraviolet irradiation (incubation in minimum media and at 42/sup 0/ C) on the irradiated strains. The results of densitometry of the membrane proteins of the initial and mutant strains point to a connection between unusual morphology, the disruption of division and the enhanced sensitivity to ultraviolet radiation on one hand and the state of the membrane components of the bacterial cell on the other.

Psychiatric research and science policy in Germany: the history of the Deutsche Forschungsanstalt fur Psychiatrie (German Institute for Psychiatric Research) in Munich from 1917 to 1945).

Science.gov (United States)

Weber, M M

2000-09-01

The Deutsche Forschungsanstalt fur Psychiatrie (DFA) in Munich, one of the most important research institutes in the field of theoretical and clinical psychiatry, was founded in 1917 by Emil Kraepelin. Its financial existence between the world wars was assured by generous donations from the Jewish American scholar and philanthropist James Loeb. The scientific work done by Walther Spielmeyer (neuropathology), Felix Plaut (serology), Kurt Schneider (clinical psychiatry) and Ernst Rudin (psychiatric genetics) earned the DFA a reputation as an international center for psychiatry and neurology. During the 'Third Reich' Ernst Rudin cooperated with the National Socialist health system. His genetic concepts provided support for eugenic programmes such as forced sterilization of individuals with psychoses. These complex interactions underscore the importance of the DFA in understanding the recent history of medicine in Germany.

The ATLAS experiment at CERN is planning full deployment of a new unified link technology for connecting detector front end electronics on the timescale of the LHC Run 4 (2025). It is estimated that roughly 8000 GBT (GigaBit Transceiver) links, with transfer rates probably up to 9.6 Gbps, will replace existing links used for readout, detector control and distribution of timing and trigger information. In particular the links used for readout are often detector-specific. Already in Run 3 this technology will be deployed in conjunction with new muon detectors, additional muon first-level triggering electronics and new on-detector and off-detector liquid argon calorimeter electronics to be used for first level triggering. A total of roughly 2000 GBT links or GBT-like links (for connecting to off-detector trigger electronics) will be needed. A new class of devices will need to be developed to interface many GBT links to the rest of the trigger, data-acquisition and detector control systems. In this paper we prese...

Asymmetric competition prevents the outbreak of an opportunistic species after coral reef degradation.

Disturbance releases space and allows the growth of opportunistic species, excluded by the old stands, with a potential to alter community dynamics. In coral reefs, abundances of fast-growing, and disturbance-tolerant sponges are expected to increase and dominate as space becomes available following acute coral mortality events. Yet, an increase in abundance of these opportunistic species has been reported in only a few studies, suggesting certain mechanisms may be acting to regulate sponge populations. To gain insights into mechanisms of population control, we simulated the dynamics of the common reef-excavating sponge Cliona tenuis in the Caribbean using an individual-based model. An orthogonal hypothesis testing approach was used, where four candidate mechanisms-algal competition, stock-recruitment limitation, whole and partial mortality-were incorporated sequentially into the model and the results were tested against independent field observations taken over a decade in Belize, Central America. We found that releasing space after coral mortality can promote C. tenuis outbreaks, but such outbreaks can be curtailed by macroalgal competition. The asymmetrical competitive superiority of macroalgae, given by their capacity to pre-empt space and outcompete with the sponge in a size-dependant fashion, supports their capacity to steal the opportunity from other opportunists. While multiple system stages can be expected in coral reefs following intense perturbation macroalgae may prevent the growth of other space-occupiers, such as bioeroding sponges, under low grazing pressure.

A variety of methods has been described to stabilise periprosthetic fractures around total knee arthroplasty (TKA). Our report offers a review of the actual strategies in the reduction and fixation of these fractures. Surgical treatment should be based on the following four steps......:Diagnostics: By taking the patients' history together with an X-ray of the knee and femur, the fracture is analysed. It is crucial to define whether any losening of the prosthesis had occurred. In selected cases, CT-scan may add important information on the stability of the implant.Classification and planning: For most...... fractures around the distal femur, the Rorabeck classification is used while fractures around the proximal tibia are best classified according to the Felix classification. Additionally the Orthopaedic Trauma Association (OTA) may be helpful in the planning process for reduction and fixation...

2017-01-01

This book presents beautiful photos of mathematical models of geometric surfaces made from a variety of materials including plaster, metal, paper, wood, and string. The construction of these models at the time (of Felix Klein and others) was not an end in itself, but was accompanied by mathematical research especially in the field of algebraic geometry. The models were used to illustrate the mathematical objects defined by abstract formulas, either as equations or parameterizations. In the second part of the book, the models are explained by experts in the field of geometry. This book is a reprint thirty years after the original publication in 1986 with a new preface by Gert-Martin Greuel. The models have a timeless appeal and a historical value.

Full Text Available The study of radicalization and de-radicalization, understood as processes leading towards the increased or decreased use of political violence, is central to the question of how political violence emerges, how it can be prevented, and how it can be contained. The focus section of this issue of the International Journal of Conflict and Violence addresses radicalization and de-radicalization, seeking to develop a more comprehensive understanding of the processes, dynamics, and mechanisms involved and taking an interdisciplinary approach to overcome the fragmentation into separate disciplines and focus areas. Contributions by Pénélope Larzillière, Felix Heiduk, Bill Kissane, Hank Johnston, Christian Davenport and Cyanne Loyle, Veronique Dudouet, and Lasse Lindekilde address repressive settings, legitimacy, institutional aspects, organizational outcomes, and dynamics in Europe, Asia, Africa, and North and South America.

Full Text Available In the last few decades, the problem of voluntary disclosure of financial or non-financial information has been, in the attention of specialists, given the fact that information assimetry, as explained by the agency theory, has become an important factor for the actors of financial markets. High quality financial reports consistent with the IAS/IFRS, issued at regular intervals, have the role of offering data for in-depth financial analisys that can be the basis for decisions regarding stock market investments. The performance of company, estimated by using the EVA, MVA, VA indicators, are directly linked with the average cost of capital, which in turn is sensitive to the evolutions of the stock market, measured both by the level of the asset attached to the entity and of the level of financial market. The impact of voluntary disclosure on company’s performance in our paper has been studied on TUFE company listed on the Bucharest Stock Exchange, confirming a refined degree of predictability.

Bioeroding sponges break down calcium carbonate substratum, including coral skeleton, and their capacity for reef erosion is expected to increase in warmer and more acidic oceans. However, elevated temperature can disrupt the functionally important microbial symbionts of some sponge species, often with adverse consequences for host health. Here, we provide the first detailed description of the microbial community of the bioeroding sponge Cliona orientalis and assess how the community responds to seawater temperatures incrementally increasing from 23°C to 32°C. The microbiome, identified using 16S rRNA gene sequencing, was dominated by Alphaproteobacteria, including a single operational taxonomic unit (OTU; Rhodothalassium sp.) that represented 21% of all sequences. The "core" microbial community (taxa present in >80% of samples) included putative nitrogen fixers and ammonia oxidizers, suggesting that symbiotic nitrogen metabolism may be a key function of the C. orientalis holobiont. The C. orientalis microbiome was generally stable at temperatures up to 27°C; however, a community shift occurred at 29°C, including changes in the relative abundance and turnover of microbial OTUs. Notably, this microbial shift occurred at a lower temperature than the 32°C threshold that induced sponge bleaching, indicating that changes in the microbiome may play a role in the destabilization of the C. orientalis holobiont. C. orientalis failed to regain Symbiodinium or restore its baseline microbial community following bleaching, suggesting that the sponge has limited ability to recover from extreme thermal exposure, at least under aquarium conditions. © 2018 John Wiley & Sons Ltd.

Full Text Available Objective: To test three marine sponges Halichondria glabrata Keller, 1891; Spirastrella pachyspira (S. pachyspira Levi, 1958 and Cliona lobata Hancock, 1849 for the presence of the acetylcholinesterase (AChE in both young and developed samples from western coastal area of India. S. pachyspira methanolic extract was selected for anti/pro angiogenic activity. Methods: They were evaluated for AChE activity using Ellman’s assay based on production of yellow colored 5-thio-2-nitrobenzoate. Purification of the enzyme was planned using ammonium sulphate precipitation and characterization by sodium dodecyl sulfate polyacrylamide gel electrophoresis. Chorioallantoic membrane (ChAM assay model was used for angiogenic/ antiangiogenic testing. Results: All the three sponges showed good specific enzyme activity and S. pachyspira contained maximum specific enzyme activity. Sixty percent of ammonium sulphate precipitation of crude protein sample gave single band at 66 kDa corresponding to the true AChE. ChAM assay was performed at 62.5, 125.0 and 250.0 µg/mL. Dosage beyond 250 µg/mL extract showed toxic response with anti angiogenic activity at all the concentrations. Conclusions: AChE activity was detected in all samples. Extract showed good anti-angiogenic response at 62.5 µg/mL. Extract was highly toxic affecting microvasculature of ChAM as well as normal growth and development of the embryo at 500 µg/mL. With further characterization of bioactive compounds from the extract of S. pachyspira, the compounds can be developed for anti tumor activity.

Interfacing Detectors and Collecting Data for Large-Scale Experiments in High Energy Physics Using COTS Technology

CERN Document Server

Schumacher, Jorn; Wandelli, Wainer

Data-acquisition systems for high-energy physics experiments like the ATLAS experiment at the European particle-physics research institute CERN are used to record experimental physics data and are essential for the effective operation of an experiment. Located in underground facilities with limited space, power, cooling, and exposed to ionizing radiation and strong magnetic fields, data-acquisition systems have unique requirements and are challenging to design and build. Traditionally, these systems have been composed of custom-designed electronic components to be able to cope with the large data volumes that high-energy physics experiments generate and at the same time meet technological and environmental requirements. Custom-designed electronics is costly to develop, effortful to maintain and typically not very flexible. This thesis explores an alternative architecture for data-acquisition systems based on commercial off-the-shelf (COTS) components. A COTS-based data distribution device called FELIX that w...

Since 2009, the Instituto de Astronomia y Fisica del Espacio keeps in development an optical observatory mainly aimed to the detection of extrasolar planets and the monitoring of stellar activity. In this framework, the telescopes Meade LX200 16 Horacio Ghielmetti in the Complejo Astronomico El Leoncito, and MATE (Magnetic Activity and Transiting Exoplanets) in the Estación de Altura at the Observatorio Astronomico Felix Aguilar were assembled. Both telescopes can operate automatically through all night, which generates a massive volume of data. Because of this, it becomes essential the automatization of the acquisition and analysis of the regular observations as well as the calibration images; in particular the flat fields. In this work a method to simplify and automatize the acquisition of these images was developed. This method uses the luminosity values of the sky, registered by a weather station located next to the observation site.

2002-01-01

Most clusters produced in the gas phase, especially those containing metals, remain largely uncharaterized, among these are transition metal - carbide, -oxide and -nitride clusters. A method for recording IR spectra of strongly bound gas-phase clusters is presented. It is based on a free-electron laser called Felix, characterized by wide wavelength tuning range, covering almost the full 'molecular finger print' region, high power and fluence which make it suited to excite gas-phase species i.e. gas -phase clusters. Neutral clusters were generated by laser vaporization technique, ions that were created after the interaction with the free-electron laser were analyzed in a flight mass spectrometer. Experiments were run with titanium carbide clusters and their IR spectra given. It was shown that this method is suited to strongly bound clusters with low ionization energies, a condition met for many pure metal clusters and metal compound clusters. (nevyjel)

Rocky Mountain spotted fever: a disease in need of microbiological concern.

Science.gov (United States)

Walker, D H

1989-01-01

Rocky Mountain spotted fever, a life-threatening tick-transmitted infection, is the most prevalent rickettsiosis in the United States. This zoonosis is firmly entrenched in the tick host, which maintains the rickettsiae in nature by transovarian transmission. Although the incidence of disease fluctuates in various regions and nationwide, the problems of a deceptively difficult clinical diagnosis and little microbiologic diagnostic effort persist. Many empiric antibiotic regimens lack antirickettsial activity. There is neither an effective vaccine nor a generally available assay that is diagnostic during the early stages of illness, when treatment is most effective. Microbiology laboratories that offer only the archaic retrospective Weil-Felix serologic tests should review the needs of their patients. Research microbiologists who tackle these challenging organisms have an array of questions to address regarding rickettsial surface composition, structure-function analysis, and pathogenic and immune mechanisms, as well as laboratory diagnosis.

Janardhanan, Jeshina; Trowbridge, Paul; Varghese, George M

2014-12-01

Scrub typhus is an acute febrile illness that, if untreated, can result in considerable morbidity and mortality. One of the primary reasons for delays in the treatment of this potentially fatal infection is the difficulty in diagnosing the condition. Diagnosis is often complicated because of the combination of non-specific symptoms that overlap with other infections commonly found in endemic areas and the poor available diagnostics. In the majority of the endemic settings, diagnosis still relies on the Weil-Felix test, which is neither sensitive nor specific. Other methods of testing have become available, but at this time, these remain insufficient to provide the rapid point-of-care diagnostics that would be necessary to significantly change the management of this infection by providers in endemic areas. This article reviews the currently available diagnostic tools for scrub typhus and their utility in the clinical setting.

The history of CERN during the early 1950s

1989-01-01

This paper, written by CERN's first secretary general, looks at the history of CERN, the first example of an intergovernmental research laboratory created in Europe, which has now been operating successfully for more than thirty years. Three distinct periods of development are identified. Early initiatives sprang from a growing sense of European union, and a desire to gain the benefits of collaboration in scale, that United States examples such as Brookhaven National Laboratory had offered. The first big project was to build a 10GeV proton-synchrotron, at that time the largest in the world. The middle era corresponds to the establishment of the organization, with personnel assembling, and buildings and plant coming on line. In October 1954, with Felix Bloch as its director general, CERN entered its final permanent form. The synchrocyclotron operated in 1958 and a proton beam circulated in the proton-synchrotron in November 1959. (UK)

Full Text Available Esse artigo busca discutir a institucionalização das perspectivas teóricas e práticas da educação ambiental, tendo como objetivo questionar se esse processo pode manter o potencial político da educação ambiental, ou se ele será responsável por sua despolitização, por transformá-la em instrumento de manutenção do poder governamental constituído, com a justificativa de ser a responsável pela salvação da espécie humana e de outros seres vivos da catástrofe ecológica que se aproxima. Para esse debate, serão utilizadas principalmente as noções de política, polícia, consenso e dissenso no trabalho de Jacques Rancière, além da ideia de grande saúde na perspectiva de Nietzsche, e das forças molares e moleculares desenvolvidas por Felix Guattari.

Geometries

Sossinsky, A B

2012-01-01

The book is an innovative modern exposition of geometry, or rather, of geometries; it is the first textbook in which Felix Klein's Erlangen Program (the action of transformation groups) is systematically used as the basis for defining various geometries. The course of study presented is dedicated to the proposition that all geometries are created equal--although some, of course, remain more equal than others. The author concentrates on several of the more distinguished and beautiful ones, which include what he terms "toy geometries", the geometries of Platonic bodies, discrete geometries, and classical continuous geometries. The text is based on first-year semester course lectures delivered at the Independent University of Moscow in 2003 and 2006. It is by no means a formal algebraic or analytic treatment of geometric topics, but rather, a highly visual exposition containing upwards of 200 illustrations. The reader is expected to possess a familiarity with elementary Euclidean geometry, albeit those lacking t...

Pf16 and phiPMW: Expanding the realm of Pseudomonas putida bacteriophages.

Directory of Open Access Journals (Sweden)

Damian J Magill

Full Text Available We present the analysis of two novel Pseudomonas putida phages, pf16 and phiPMW. Pf16 represents a peripherally related T4-like phage, and is the first of its kind infecting a Pseudomonad, with evidence suggesting cyanophage origins. Extensive divergence has resulted in pf16 occupying a newly defined clade designated as the pf16-related phages, lying at the interface of the Schizo T-Evens and Exo T-Evens. Recombination with an ancestor of the P. putida phage AF is likely responsible for the tropism of this phage. phiPMW represents a completely novel Pseudomonas phage with a genome containing substantial genetic novelty through its many hypothetical proteins. Evidence suggests that this phage has been extensively shaped through gene transfer events and vertical evolution. Phylogenetics shows that this phage has an evolutionary history involving FelixO1-related viruses but is in itself highly distinct from this group.

Full Text Available Scrub typhus is an acute infectious illness, distributed throughout the Asia Pacific rim. In India, it has been reported from northern, eastern, and southern India. However, cases of scrub typhus have not been well-documented from Vidarbha, an eastern region of Maharashtra state in central India. We report two cases of complicated scrub typhus from Vidarbha region. These cases admitted in unconscious state with 8-10 days history of fever, body ache, cough, and progressive breathlessness. The diagnosis in both cases was based on presence of eschar, a positive Weil-Felix test, and a positive rapid diagnostic test (immunochromatographic assay. Both cases were complicated by acute respiratory distress syndrome (ARDS and multiorgan failure. Both of them presented in their 2 nd week of illness and died during the hospital course in spite of intensive supportive care. The main cause of mortality was delayed referral leading to delay in diagnosis and treatment.

ON POLISH FANTASTIC LITERATURE FOR YOUNG PEOPLE AND ITS THERAPEUTIC POTENTIAL

Directory of Open Access Journals (Sweden)

Dominik Borowski

2017-04-01

Full Text Available The objective of this article is to provide an overview of the therapeutic potential of fantastic literature for young people on the example of the series of novels by Rafał Kosik. The paper consists of three parts. The first part presents the definition of fantastic literature with reference to the concepts introduced by Tzvetan Todorov, Roger Caillois, Eric Rabkin and dictionary entries. Then the therapeutic function of literature is discussed by citing psychological theses on the importance of narrative in human life, as well as Roman Ingarden’s theory of the aesthetic experience. This provides the basis for reflection on bibliotherapy and the use of fantastic literature within its framework. The third part of the article presents the concept of the series of novels about Felix, Net and Nika, referring to the opinions of critics and literary scholars. Subsequently the selected fragments of the novels are discussed, demonstrating their therapeutic potential.

Egyptian imprints on Geto-Dacian magical medicine.

Baran, Dana

2010-12-01

Several characteristics of Egyptian culture and civilization could be identified in prehistoric and ancient historic Geto-Dacian territories, belonging to modern Romania (Fig. 1). From early times, magic, religion and philosophy have been part of pre-scientific medicine. Therefore these aspects are to be tackled when speaking of medicine in mythological or legendary ages. Progress of ancient Geto-Dacian medicine was principally ascribed to the interface of local civilizations with ancient Egypt, Greece and Rome. Such connections were well documented and understood in historic times and were mainly based on texts of renowned Greek and Roman historians. Egyptian impact upon Dacia, -the ancient name of today's Romania-, was often explained in terms of indirect Greek- or Roman-mediated influences.The Greek and then the Roman colonies on the Black sea shore, together with later Roman colonies in Dacia Felix, founded in the heart of Transylvania, enabled access for Romania to Mediterranean cultures, including that of Egypt.

Acetylsalicylic acid: Incoming 150 years of the first synthesis

Mijin Dušan Ž.

2002-01-01

Full Text Available Acetylsalicylic acid is one of the most fascinating and versatile drugs known to medicine, as well as one of the oldest. Acetylsalicylic acid is a drug which is safe, with analgetic, antirheumatic, anti-inflammatory antiplatelet and antithrombotic action. It may be applied not only in clinical practice, but also as prevention. The first known use of an acetylsalicylic acid-like preparation can be traced to ancient Greece. In 1853 Charles Gerhardt published the first synthesis of acetylsalicylic acid. Felix Hoffmann, a chemist for Friedrich Bayer, a German dye company obtained a patent on acetylsalicylic acid some 40 years later. Bayer coined the name Aspirin for the new product. The 20 in century was the century in which many researchers in many companies tried to improve the synthesis of acetylsalicylic acid not only in terms of yield but also purity. This paper describes the history, use, mechanism of action, synthesis and production as well as the purification and stability of acetylsalicylic acid.

Fractal Geometry in the Arts: AN Overview across the Different Cultures

Science.gov (United States)

Sala, Nicoletta

Fractal, in mathematics, is a geometric shape that is complex and detailed in structure at any level of magnification. The word "fractal" was coined less than thirty years ago by one of history's most creative and mathematicians, Benoit Mandelbrot, whose work, The Fractal Geometry of Nature, first introduced and explained concepts underlying this new vision of the geometry. Although other mathematical thinkers like Georg Cantor (1845-1918), Felix Hausdorff (1868-1942), Gaston Julia (1893-1978), Helge von Koch (1870-1924), Giuseppe Peano (1858-1932), Lewis Richardson (1891-1953), Waclaw Sierpinski (1882-1969) and others had attained isolated insights of fractal understanding, such ideas were largely ignored until Mandelbrot's genius forged them at a single blow into a gorgeously coherent and fascinating discipline. Fractal geometry is applied in different field now: engineering, physics, chemistry, biology, and architecture. The aim of this paper is to introduce an approach where the arts are analysed using a fractal point of view.

The rotameter and the waterwheel.

Foregger, R

2001-09-01

The publication imparts information about the personal life and professional sphere of activity of J.A. Segner, Karl Küppers, Maximilian Neu, Hans Bunte, and Felix Meyer, as far as they were involved with the invention of devices for measuring gas flow, especially their involvement in testing the introduction of Rotameters into the medical field. The knowledge that the threat of deportation in October 1940, due to his Jewish background and in view of the politics of the National Socialists at the time, led to Maximilian Neu's committing suicide, is of added historical interest. Together with biographical details, the role played by the Institute of Research in Karlsruhe and the establishment of the Rotameter site in Aachen is presented. The historical outline finishes with a short report of the author's first experience with Rotameters at the Nuffeld Department of Anaesthetics, Oxford University during the Second World War and with his subsequent efforts to introduce Rotameters into anesthesia equipment design in the United States.

The delirium of change: Giles Deleuze’s optimistic postmodernism

Directory of Open Access Journals (Sweden)

Geoffrey Wood

1997-03-01

Full Text Available Giles Deleuze’s theories of domination and change represent a radical departure from both modern radicalism and the nihilism of many postmodernists. Deleuze has developed a comprehensive critique of domination within societies, and offers an alternative vision, based on the rejection of the routinized patterning of the individual's life experiences. One of his major works, Capitalism and Schizophrenia (1988 was written in collaboration with Felix Guattari. An ex-psychoanalyst, Guattari brought a specific focus to bear on the limitations of conventional approaches to therapy, its wider social implications and the alternatives thereto, a theme which is absent in Deleuze's later works. It is argued that while this vision provides a totally different alternative to many of the tired debates surrounding order and revolution, by its very nature it is limited, designed to appeal to a limited grouping of insiders, and is inadequately equipped to deal with the negative face of localised ethno-particularism which has emerged in the 1990s.

Foucault and the 'Anti-Oedipus movement': psychoanalysis as disciplinary power.

Science.gov (United States)

Basaure, Mauro

2009-09-01

What psychiatry was for the anti-psychiatry movement, psychoanalysis was for the French 'Anti-Oedipus movement' represented by Robert Castel, Gilles Deleuze and Felix Guattari. Until now, the contribution of Foucault to this critical movement has been little known. In this paper I reconstruct in a systematic and exhaustive way Foucault's critique of psychoanalysis and, in particular, of the Oedipus-complex theory. I demonstrate that this critique presupposes a very specific epistemology and social theory. On an epistemological level, Foucault focuses on the power effects of psychoanalysis as a discourse of subjectivity. On a social-theoretical level, Foucault assumes a functionalist conception of society. These two aspects of Foucault's critique of psychoanalysis have not been adequately recognized in the discussion about his relationship to psychoanalysis (Derrida, Miller, Whitebook, among others). I argue that a fruitful dialogue between a Foucault-inspired critical social theory and psychoanalysis can take place only if these two distinct aspects are taken into account.

Modeling of criticality accidents and their environmental consequences

International Nuclear Information System (INIS)

Thomas, W.; Gmal, B.

1987-01-01

In the Federal Republic of Germany, potential radiological consequences of accidental nuclear criticality have to be evaluated in the licensing procedure for fuel cycle facilities. A prerequisite to this evaluation is to establish conceivable accident scenarios. First, possibilities for a criticality exceeding the generally applied double contingency principle of safety are identified by screening the equipment and operation of the facility. Identification of undetected accumulations of fissile material or incorrect transfer of fissile solution to unfavorable geometry normally are most important. Second, relevant and credible scenarios causing the most severe consequences are derived from these possibilities. For the identified relevant scenarios, time-dependent fission rates and reasonable numbers for peak power and total fissions must be determined. Experience from real accidents and experiments (KEWB, SPERT, CRAC, SILENE) has been evaluated using empirical formulas. To model the time-dependent behavior of criticality excursions in fissile solutions, a computer program FELIX has been developed

Kohl, F

This article describes the historic roots of acetylsalicylic acid (ASA) from the first experiments at 1800 until the introduction into the pharmaceutical market in 1899. In 1869, Hermann Kolbe enlightened the chemical structure of salicylic acid, which was used at that time as an analgetic and antipyretic drug. Because of the side effects, for example the irritation of the stomach, analytical chemists and pharmacologists searched for chemical modifications. In August 1897 Felix Hoffmann (1868-1946) was successful in acetylizing the salicylic acid to acetylsalicylic acid (ASA). Between 1897 and 1899 Kurt Witthauer (1865-1911) collected clinical data and experiences on the efficiency of ASA as an analgetic and antipyretic drug. In 1899 ASA was introduced into the pharmaceutical market as Aspirin and became soon one of the most successful drugs of its time. The indication exceeds analgesia in the mean time and to prophylaxis of myocardial ischaemia or cerebral stroke, among others.

Development and commissioning of a double-prism spectrometer for the diagnosis of femtosecond electron bunches

Energy Technology Data Exchange (ETDEWEB)

Wunderlich, Steffen

2016-12-15

Free-electron lasers as accelerator-driven light sources and wakefield-based acceleration in plasmas require the knowledge of the longitudinal extension and the longitudinal current profile of the involved electron bunches. These bunches can yield lengths below 10 μm, or durations shorter than approx. 33 fs, as well as charges less than 30 pC. During this work, transition radiation from relativistic electron bunches was investigated in the mid-infrared wavelength regime. A spectrometer using an arrangement of two consecutive zinc selenide prisms was developed, built and commissioned. The instrument covers the spectral range from 2 μm to 18 μm in a single shot. Measurements with the double-prism spectrometer were conducted at the FEL facilities FLASH at DESY in Hamburg, Germany and FELIX at the Radboud Universiteit in Nijmegen, The Netherlands. The assessment of the spectrometer and comparative studies with established diagnostic devices at FLASH show high signal-to-noise ratios at bunch charges below 10 pC and confirm the obtained results.

Sponge biomass and bioerosion rates increase under ocean warming and acidification.

The combination of ocean warming and acidification as a result of increasing atmospheric carbon dioxide (CO2 ) is considered to be a significant threat to calcifying organisms and their activities on coral reefs. How these global changes impact the important roles of decalcifying organisms (bioeroders) in the regulation of carbonate budgets, however, is less understood. To address this important question, the effects of a range of past, present and future CO2 emission scenarios (temperature + acidification) on the excavating sponge Cliona orientalis Thiele, 1900 were explored over 12 weeks in early summer on the southern Great Barrier Reef. C. orientalis is a widely distributed bioeroder on many reefs, and hosts symbiotic dinoflagellates of the genus Symbiodinium. Our results showed that biomass production and bioerosion rates of C. orientalis were similar under a pre-industrial scenario and a present day (control) scenario. Symbiodinium population density in the sponge tissue was the highest under the pre-industrial scenario, and decreased towards the two future scenarios with sponge replicates under the 'business-as-usual' CO2 emission scenario exhibiting strong bleaching. Despite these changes, biomass production and the ability of the sponge to erode coral carbonate materials both increased under the future scenarios. Our study suggests that C. orientalis will likely grow faster and have higher bioerosion rates in a high CO2 future than at present, even with significant bleaching. Assuming that our findings hold for excavating sponges in general, increased sponge biomass coupled with accelerated bioerosion may push coral reefs towards net erosion and negative carbonate budgets in the future. © 2013 John Wiley & Sons Ltd.

Sponge erosion under acidification and warming scenarios: differential impacts on living and dead coral.

Stubler, Amber D; Furman, Bradley T; Peterson, Bradley J

2015-11-01

Ocean acidification will disproportionately impact the growth of calcifying organisms in coral reef ecosystems. Simultaneously, sponge bioerosion rates have been shown to increase as seawater pH decreases. We conducted a 20-week experiment that included a 4-week acclimation period with a high number of replicate tanks and a fully orthogonal design with two levels of temperature (ambient and +1 °C), three levels of pH (8.1, 7.8, and 7.6), and two levels of boring sponge (Cliona varians, present and absent) to account for differences in sponge attachment and carbonate change for both living and dead coral substrate (Porites furcata). Net coral calcification, net dissolution/bioerosion, coral and sponge survival, sponge attachment, and sponge symbiont health were evaluated. Additionally, we used the empirical data from the experiment to develop a stochastic simulation of carbonate change for small coral clusters (i.e., simulated reefs). Our findings suggest differential impacts of temperature, pH and sponge presence for living and dead corals. Net coral calcification (mg CaCO3  cm(-2)  day(-1) ) was significantly reduced in treatments with increased temperature (+1 °C) and when sponges were present; acidification had no significant effect on coral calcification. Net dissolution of dead coral was primarily driven by pH, regardless of sponge presence or seawater temperature. A reevaluation of the current paradigm of coral carbonate change under future acidification and warming scenarios should include ecologically relevant timescales, species interactions, and community organization to more accurately predict ecosystem-level response to future conditions. © 2015 John Wiley & Sons Ltd.

This work shows the strategy followed for the co-location of the Satellite Laser Ranging (SLR) ILRS 7406 telescope and the antenna of the permanent Global Positioning System (GPS) station, located at the Félix Aguilar Astronomical Observatory (OAFA) in San Juan, Argentina. The accomplishment of the co-location consisted in the design, construction, measurement, adjustment and compensation of a geodesic net between the stations SLR and GPS, securing support points solidly built in the soil. The co-location allows the coordinates of the station to be obtained by combining the data of both SLR and GPS techniques, achieving a greater degree of accuracy than individually. The International Earth Rotation and Reference Systems Service (IERS) considers the co-located stations as the most valuable and important points for the maintenance of terrestrial reference systems and their connection with the celestial ones. The 3 mm precision required by the IERS has been successfully achieved.

Full Text Available The post-modern society, especially in westernized cultures, has the peculiarity of the presence of some components: capitalism, power systems, technologies for their exercise, schizophrenic behavior, fortification of segregation and repression actions. This is the political, social and cultural background of the School: an institution that seeks the adjustment of individuals to civic life and labor. Based on some ideas of Michel Foucault and the duo consisting of Gilles Deleuze and Felix Guattari the analysis of the instruments of power and the actions contained therein is made. Besides these, we present the definitions of concepts supported Marc Auge, on the characteristics of non-place in supermodernity, a place devoid of experience; Donna Haraway, with its ciborgologia, offering the chance to replace the dichotomy of man versus machine by an ontology human-machine and Jeffrey Jerome Cohen, who in seven theses on the monsters, look back to the monstrosity that surrounds us. It is so identified the element that the School intend to reach: an infant and monstrous cyborg who is required to remain in a non-place.

No wonder you wonder! great inventions and scientific mysteries

Phipps, Claude

2016-01-01

This book explores and explains scientific mysteries and principles, leavened with tongue-in-cheek humor and an abundance of illustrations. Chapters are short, but give an understanding of technology and science not available elsewhere. Questions include: • What holds a satellite up while it goes around the Earth? • Why is the sky (made out of clear air!) blue instead of green, or just black as night like the sky that high altitude jumper Felix Baumgartner saw? • How is laser light different from “normal” light? • Did Columbus really discover that the Earth is round? • Which one invention will assuredly survive our civilization? • Why can’t you travel back in time?  If you often feel embarrassed because you don’t have a clue about lasers, the difference between volts, amps and watts, or how jet planes really work – but you would like to understand the physical principles of our modern world, whether you’re a teen or a parent – this book is for you! To understand the basics of quantu...

Nuclear medicine diagnosis of pulmonary embolism

Pulmonary embolism is an emergency situation. The earlier therapy begins, the more effective it will be. This, however, asks for immediate diagnosis. At present the most effective method of diagnosing and localizing pulmonary embolism is perfusion scintiscan of the lung. It should be completed by chest radiography to exclude peripheral infiltration and/or central lung cancer. Generally, these two procedures ensure optimal diagnosis. In case of additional disease of the pleura, mediastinum and lung parenchyma, further measures may be necessary: especially in chronic obstructive lung disease ventilation perfusion ratio and outwash of xenon might be helpful. Scintiscan of the lung is suited for early diagnosis as well as for follow-up examinations. Only if thrombectomy is planned, pulmonary angiography should be preferred. Scintiscan of the lung with marked particle suspensions ensures a minimum of complications. There is only one incident in 10 000 examinations. According to Quinn (1964) and Felix (1971) pulmonary scintiscan might be harmful in patients with right heart failure. We made no such observation in 4000 cases.

Full Text Available Felix Bovie first made a career as a landscape painter. Later on however, he completely devoted himself to the writingof poetic texts for songs he interpreted himself as a mid-19th-century singer songwriter. A scion of a wealthy familyliving in the Belgian capital, he frequented bourgeois associations such as the Masonic lodges but he was also an adeptof more bohemian, frolicsome societies who liked to mock Freemasonry as such. The song text production of Bovie,which has often been compared to the one of French liberalsinger Béranger, can only beunderstood in the interface ofall those specific spheres. There, artistic and more saucy motives went alongdefinitely anticlerical and particularMasonic themes. Bovie had been accepted by theAmis Philanthropeslodge but eventually left for another Brusselslodge that rejected the politically militant kind of Freemasonry theformer advocated. The songs Bovie wrote andperformed celebrated a spiritualist and convivial Freemasonry,that surely was apolitical but nevertheless provedfrankly anticlerical, if only as a reaction against the Belgian episcopal condemnation of Freemasonry of 1837.

A Surgeon’s View on Endarterectomy and Stenting in 2011: Lest We Forget, It’s All About Preventing Stroke

International Nuclear Information System (INIS)

Naylor, A. Ross

2012-01-01

It has been nearly 60 years since Felix Eastcott published his seminal paper on carotid reconstruction, which paved the way for carotid endarterectomy (CEA) and then carotid artery stenting (CAS) to assume prominent roles in the prevention of stroke. Yet the ensuing 60 years has witnessed repeated cycles of challenges to practice, professional mistrust, conflicts of interest, dogmatic retention of traditional management strategies, inappropriate corporate interventions, and a general failure to adapt to new evidence. Even the performance of large-scale randomised trials has been associated with rancour and a lack of consensus. This article reviews the history of invasive interventions in the treatment of carotid disease and makes a plea to both the surgical and interventional communities that the fundamental priority must always be the prevention of stroke. It concludes with an appeal for colleagues to collaborate to determine how best to treat patients during the hyperacute period after the onset of symptoms and to identify a smaller cohort of asymptomatic patients who are truly at high risk for stroke in whom to target CAS or CEA.

Use of time space Green's functions in the computation of transient eddy current fields

International Nuclear Information System (INIS)

Davey, K.; Turner, L.

1988-01-01

The utility of integral equations to solve eddy current problems has been borne out by numerous computations in the past few years, principally in sinusoidal steady-state problems. This paper attempts to examine the applicability of the integral approaches in both time and space for the more generic transient problem. The basic formulation for the time space Green's function approach is laid out. A technique employing Gauss-Laguerre integration is employed to realize the temporal solution, while Gauss--Legendre integration is used to resolve the spatial field character. The technique is then applied to the fusion electromagnetic induction experiments (FELIX) cylinder experiments in both two and three dimensions. It is found that quite accurate solutions can be obtained using rather coarse time steps and very few unknowns; the three-dimensional field solution worked out in this context used basically only four unknowns. The solution appears to be somewhat sensitive to the choice of time step, a consequence of a numerical instability imbedded in the Green's function near the origin

A short history of anti-rheumatic therapy. II. Aspirin

Directory of Open Access Journals (Sweden)

P. Marson

2011-06-01

Full Text Available The discovery of aspirin, an antipyretic, anti-inflammatory and analgesic drug, undoubtedly represents a milestone in the history of medical therapy. Since ancient times the derivatives of willow (Salix alba were used to treat a variety of fevers and pain syndromes, although the first report dates back to 1763 when the English Reverend Edward Stone described the effect of an extract of the bark willow in treating malaria. In the XIX century many apothecaries and chemists, including the Italian Raffaele Piria and Cesare Bertagnini, developed the biological processes of extraction and chemical synthesis of salicylates, and then analyzed their therapeutic properties and pharmacokinetic and pharmacodynamic characteristics. In 1899 the Bayer Company, where Felix Hoffmann, Heinrich Dreser and Arthur Eichengrün worked, recorded acetyl-salicylic acid under the name “Aspirin”. In the XX century, besides the definition of the correct applications of aspirin in the anti-rheumatic therapy being defined, Lawrence L. Crawen identified the property of this drug as an anti-platelet agent, thus opening the way for more widespread uses in cardiovascular diseases.

Para la comunidad médica en general y la informática en particular constituye especial novedad la aparición de este libro.

Su autor, cirujano e insigne educador médico, preocupado por las ciencias de la información como esencial elemento educativo desde sus inicios, en la década de los 70s, introdujo, en colaboración entre FEPAFEM, COLCIENCIAS y la Fundación OFA para las Ciencias Biomédicas, en 1981, el primer programa de conexión en línea con el banco de datos de la Biblioteca Nacional de Medicina de los Estados Unidos (MEDLINE.

El programa INFORMED, así llamado, constituyó una verdadera revolución tanto para los investigadores como para las Facultades de Medicina, que vieron asomarse una nueva dinámica de la información, en ese momento manejada sólo ocasionalmente por los grandes computadores de la época.

Pero que en unos años daría paso a los mini y luego a los microcomputadores personales, hoy en día familiares para todo el mundo. En 20 años ello ha acarreado lo que él denomina un cambio de paradigma, de la biomedicina a la infomedicina, representando el ubicuo computador personal un instrumento de excelencia para la amplificación intelectual.

El libro de 245 páginas, pulcramente editado por Panamericana Editorial Ltda., está dedicado a su familia y al profesor Harry S.N.Greene, de Yale, quien según él lo introdujo por la investigación quirúrgica y, a través de ella, por el método científico. Tiene un prólogo escrito por el ingeniero y humanista José Fernando Isaza Delgado, uno de los auténticos mecenas del arte, la investigación y la educación en Colombia. Se divide en un prefacio y 12 capítulos, que van desde las llamadas “segundas revoluciones”, médica e industrial, hasta las proyecciones futuras de la teoría del caos, la inteligencia y la vida artificiales, la medicina basada en la evidencia y el futuro del libro impreso y lo que serán las nuevas autopistas de la información, algunas de ellas ya en crisis por exceso y no por defecto, como parece estar sucediendo con Internet.

Termina con un utilísimo glosario o léxico de los términos más comúnmente usados en la nueva informática, de trascendental importancia para los no iniciados.

El autor acepta o introduce anglicismos o neologismos sin inhibición alguna, convencido de la necesidad de crear un nuevo lenguaje de la ciencia. Como lo ha afirmado varias veces, él espera que el computador personal sustituya, para las nuevas generaciones, al microscopio, que se insinuaba como herramienta necesaria para los médicos de los primeros tres cuartos del siglo XX.

La presentación del libro, en la Academia Nacional de Medicina, estuvo a cargo del autor, quien manifestó que el propósito fundamental del mismo es explicar la transición del paradigma de la biomedicina a la infomedicina, haciéndolo a través del análisis de las teorías de la comunicación y de la información; del papel del computador como instrumento supremo de amplificación intelectual; de la cibernética como fundamento para el desarrollo de la inteligencia artificial y -quizás en el futuro- de la misma vida artificial; de la medicina basada en la evidencia y de sus limitaciones ante la incertidumbre en el comportamiento de los organismos complejos según la teoría del caos; y del papel de las redes de información en la estructura de una nueva “inteligencia médica”...

The primary health care in rural areas in Austria is currently determined by challenges such as ageing of the population, the shift towards chronic and age-related illnesses, the specialist medical and hospital-related education and training of physicians' as well growing widespread difficulty of staffing doctor's office. The objective is to realize a general practitioner centered and team-oriented primary health care (PHC) approach by establishing networked primary health care in rural areas of Austria. Using literature research, online survey, expert interviews and expert workshops, we identified different challenges in terms of primary health care in rural areas. Further, current resources and capacities of primary health care in rural areas were identified using the example of the district of Rohrbach. Twelve design dimensions and 51 relevant measurement indicators of a PHC network were delineated and described. Based on this, 12 design approaches of PHC concept for the GP-centered and team-oriented primary health care in rural areas have been developed.

Theoretical analysis of saturation and limit cycles in short pulse FEL oscillators

We derive a model for the non linear evolution of a short pulse oscillator from low signal up to saturation in the small gain regime. This system is controlled by only two independent parameters: cavity detuning and losses. Using a closure relation, this model reduces to a closed set of 5 non linear partial differential equations for the EM field and moments of the electron distribution. An analysis of the linearised system allows to define and calculate the eigenmodes characterising the small signal regime. An arbitrary solution of the complete nonlinear system can then be expanded in terms of these eigenmodes. This allows interpreting various observed nonlinear behaviours, including steady state saturation, limit cycles, and transition to chaos. The single mode approximation reduces to a Landau-Ginzburg equation. It allows to obtain gain, nonlinear frequency shift, and efficiency as functions of cavity detuning and cavity losses. A generalisation to two modes allows to obtain a simple description of the limit cycle behaviour, as a competition between these two modes. An analysis of the transitions to more complex dynamics is also given. Finally, the analytical results are compared to the experimental data from the FELIX experiment.

Going Deeper or Flatter: Connecting Deep Mapping, Flat Ontologies and the Democratizing of Knowledge

Directory of Open Access Journals (Sweden)

Selina Springett

2015-10-01

Full Text Available The concept of “deep mapping”, as an approach to place, has been deployed as both a descriptor of a specific suite of creative works and as a set of aesthetic practices. While its definition has been amorphous and adaptive, a number of distinct, yet related, manifestations identify as, or have been identified by, the term. In recent times, it has garnered attention beyond literary discourse, particularly within the “spatial” turn of representation in the humanities and as a result of expanded platforms of data presentation. This paper takes a brief look at the practice of “deep mapping”, considering it as a consciously performative act and tracing a number of its various manifestations. It explores how deep mapping is a reflection of epistemological trends in ontological practices of connectivity and the “flattening” of knowledge systems. In particular those put forward by post structural and cultural theorists, such as Bruno Latour, Gilles Deleuze, and Felix Guattari, as well as by theorists who associate with speculative realism. The concept of deep mapping as an aesthetic, methodological, and ideological tool, enables an approach to place that democratizes knowledge by crossing temporal, spatial, and disciplinary boundaries.

Diagnostic evaluation of rapid tests for scrub typhus in the Indian population is needed.

Science.gov (United States)

Shivalli, Siddharudha

2016-05-12

Owing to frequent outbreaks witnessed in different parts of the country in the recent past, scrub typhus is being described as a re-emerging infectious disease in India. Differentiating scrub typhus from other endemic diseases like malaria, leptospirosis, dengue fever, typhoid, etc. is difficult due to overlapping clinical features and a lower positivity for eschars in Asian populations. Hence, the diagnosis heavily relies on laboratory tests. Costs and the need of technical expertise limit the wide use of indirect immunoperoxidase or immunofluorescence assays, ELISA and PCR. The Weil-Felix test is the most commonly used and least expensive serological test, but lacks both sensitivity and specificity. Hence, the diagnosis of scrub typhus is often delayed or overlooked. With due consideration of the cost, rapidity, single test result and simplicity of interpretation, rapid diagnostic tests have come into vogue. However, evaluation of rapid diagnostic tests for scrub typhus in the Indian population is needed to justify or discourage their use. Research studies are needed to find the most suitable test in terms of the rapidity of the result, simplicity of the procedure, ease of interpretation and cost to be used in the Indian populace.

Destiny of the wood blocks which have been used for engraving of illustrations of 1543 edition of the Fabrica is really outstanding. Several times lost and found again, they were transported over Europe in a surprising conservation state, for more than four centuries. Made by the famous Venitian wood-cutters, the blocks cross the Alps to join up Basel in Switzerland and Joannes Oporinus, the printer. Felix Platter uses 48 Vesalian wood-blocks for his own treaty in 1583. These blocks reappear in Augsburg in 1706, at the printer Andreas Maschenbauer's; they are found again by Von Wollter from Ingolstadt: they are used to illustrate Leveling's anatomy book in 1781 and 1783. Ingolstadt university and the blocks will be transferred to Landshut because of Napoleon's war, then to Munich in 1826. But in 1892 147 blocks are found again in the library; and are forgotten again. Forty years after, 230 blocks are discovered again! Icones anatomicae represent the last and fabulous edition made in 1934. The Second World War closes this epic with the library fire on July 13th 1944: none of these precious blocks remains today.

[Historical notes on the terms "glaucoma" and "cataract" (author's transl)].

Rintelen, F

1977-02-01

The Greek term "glaucoma" has nothing to do with the disease we call glaucoma today and that we use to translate incorrectly with "grüner Star" throughout the German-speaking countries. The Greek adjective "glaucos" does not mean green but gleaming, sparkling. It signified the discolouring of the pupil in glaucoma. It was later replaced by the pathogenetic term hypochysis, Latin suffusio, denoting the supposed "trübe Feuchte" (opaque humour) that was taught to gather and congeal in front of the crystalline lens. Later on "glaukosis" was reserved for incurable cases, disease of the crystalline lens itself, which was looked at as the "organon visus" up to Felix Plater. The word "cataract"--waterfall--does not exist in Greek medicine. It appears in Salernitan medical science around the year 1000 as a synonym for hypochysis, the disease we call cataract today and which has been identified as opacity of the lens since Brisseau (1705). The nature of "incurable" glaucoma, later considered as a disease of the vitreous body, was clearly recognized as a consequence of intraocular increase of pressure only by v. Graefe.

No contexto do método da cartografia, o artigo tem como objetivo tratar do tema do comum num duplo aspecto. Num primeiro, discute o acesso ao plano comum. Com base em Gilles Deleuze e Felix Guattari, tal plano não é dito homogêneo nem reúne atores que manteriam entre si relações de identidade, mas opera comunicação entre singularidades, sendo pré-individual e coletivo. Num segundo aspecto, aponta que, enquanto pesquisa-intervenção, a cartografia se compromete com a criação de um mundo comum e heterogêneo.

Ambivalent journeys of hope: embryonic stem cell therapy in a clinic in India.

Science.gov (United States)

Prasad, Amit

2015-03-01

Stem cell therapy in non-Western countries such as India has received a lot of attention. Apart from media reports, there are a number of social science analyses of stem cell policy, therapy, and research, their ethical implications, and impact of advertising on patients. Nevertheless, in the media reports as well as in academic studies, experiences of patients, who undertake overseas journeys for stem cell therapy, have largely been either ignored or presented reductively, often as a "false hope." In this article, I analyze the experiences of patients and their "journeys of hope" to NuTech Mediworld, an embryonic stem cell therapy clinic in New Delhi, India. My analysis, which draws on my observations in the clinic and patients' experiences, instead of seeking to adjudicate whether embryonic stem cell therapy in clinics such as NuTech is right or wrong, true or false, focuses on how patients navigate and contest these concerns. I utilize Gilles Deleuze and Felix Guattari's "concepts," lines of flight and deterritorialization, to highlight how embryonic stem cell therapy's "political economy of hope" embodies deterritorialization of several "regimes of truth" and how these deterritorializations impact patients' experiences. © The Author(s) 2014.

Methods/Design Patients (age 40-85 presenting with intermittent neurogenic claudication due to lumbar spinal stenosis lasting more than 3 months refractory to conservative treatment, are included. Randomization into interspinous implant surgery versus bony decompression surgery will take place in the operating room after induction of anesthesia. The primary outcome measure is the functional assessment of the patient measured by the Zurich Claudication Questionnaire (ZCQ, at 8 weeks and 1 year after surgery. Other outcome parameters include perceived recovery, leg and back pain, incidence of re-operations, complications, quality of life, medical consumption, absenteeism and costs. The study is a randomized multi-institutional trial, in which two surgical techniques are compared in a parallel group design. Patients and research nurses are kept blinded of the allocated treatment during the follow-up period of 1 year. Discussion Currently decompressive laminotomy is the golden standard in the surgical treatment of lumbar spinal stenosis. Whether surgery with interspinous implants is a reasonable alternative can be determined by this trial. Trial register Dutch Trial register number: NTR1307

PREACHER AS A CHARACTER IN THE CREATIVE WORK OF LEO TOLSTOY AND GEORGE ELIOT

2014-11-01

Full Text Available The article analyzes characters of clergymen and the process of creating a specifi c type of a preacher in Leo Tolstoy’s works. The researcher tries to prove that this process was strongly infl uenced by Tolstoy’s close attention to the preacher characters in George Eliot’s works. This can be proved by Tolstoy’s letters, diary and notes in the books from the writer’s personal library. The main features of Tolstoy’s preacher character are demonstrated by the example of Prince Nekhlyudov (Resurrection. Proclaiming evangelical truth, he is not a member of any confession; he does not promulgate his views, but he proves his case by his actions and his way of life. He rejects earthly comfort and goods and voluntarily becomes integrated into people’s life. Having walked his way of repentance of former sins, he cultivates the ability to forgive and have mercy. George Eliot also accents these features in the key characters of her books, analyzed in this article (Janet’s repentance, Adam Bede and Felix Holt, the Radical. Eliot’s version of preaching becomes a certain guide for Tolstoy in the process of shaping a new type of character in his late works.

The anatomy of a forbidden desire: men, penetration and semen exchange.

The rising popularity of unprotected anal sex (bareback sex) among men who have sex with men (MSM) is perplexing healthcare providers working in sexual health clinics. Epidemiological research on the topic overlooks several socio-cultural and psychological dimensions. Our research attempts to construct an appropriate theoretical edifice by which we can understand this sexual practice. In order to achieve this objective, a qualitative design was selected and 18 semiconductive in-depth interviews were carried out with barebackers from five European and North American cities. We then analyzed the data using two theoretical approaches that were sensitive to the issues of desire, transgression and pleasure. These theories are those of the late French psychoanalyst, Jacques Lacan, and those of poststructural thinkers, Gilles Deleuze and Felix Guattari. These theoretical frameworks helped shed light on the significance of bareback sex, and can potentially influence healthcare providers in gaining a better understanding not only of their clients, but also of their own role in the circuitry of desire at work within bareback. We found that while the exchange of semen constitutes a dangerous and irrational practice to healthcare professionals, it is nevertheless a significant variable in the sexual lives of barebackers that needs to be taken into consideration in the provision of healthcare services.

Full Text Available The paper presents cultural projects and international co-operation primarily regional type, in which are included the local archaeological sites, in order to point to the experience and the benefits derived from them. Besides the promotion of tourism aimed at the wider European market, where the cultural roads linking the heritage of Europe with the intention of better understanding of a common identity, significant results were achieved in the presentation of some sites from the time of the Roman domination in Serbia. Thanks to the application of modern technologies, and monitoring global trends in the protection of heritage, prominent sites such as Viminacium, Sirmium, Felix Romuliana and Mediana, have achieved self-sufficiency and provided local economic prosperity. However, despite the positive examples listed, it was concluded that in solving problems related to the preparation of archaeological sites as tourist attractions there must be a systematic approach and support by the appropriate institutions with interconnection and cooperation. Also, on this occasion, the importance of the education of the local population was highlighted as well as the need to intensify formal education of the younger generations, which can significantly raise awareness of the necessity of preserving national heritage, as the first and perhaps the most important step in this process.

Complementing Mathematics Teachers’ Horizon Content Knowledge with an Elementary-on-Advanced Aspect

Full Text Available Although Ball and her colleagues provided empirical evidence to support the existence of the six sub-domains in mathematical knowledge for teaching (MKT and further explained or defined the majority of these sub-domains, there were few explanations of what horizon content knowledge (HCK embedded in MKT meant and they merely provided ideas about HCK. Many researchers attempted to provide some teaching incidents and exemplification to interpret the construct of HCK. Moreover, they thought teachers’ studies of tertiary mathematics are useful for classroom teaching practice. Their discourse and instantiation of HCK was correspondent with a higher perspective on elementary mathematics mentioned by Felix Klein (1924, but was not entirely coincide with a kind of elementary perspective on advanced knowledge introduced by Ball and Bass (2009. This study lasted 1 years, and data collection included in-depth interviews, classroom observation and video analysis. We provide a shared classroom teaching incidence and illustrations to explain and to describe the construct of HCK. HCK not only is a kind of elementary perspective on advanced mathematical knowledge, but also complements to a higher perspective on elementary mathematics. Furthermore, HCK could be seen as a reciprocal pathway between the elementary and advanced mathematical knowledge.

Coupling between eddy current and deflection in cantilevered beams in magnetic fields

International Nuclear Information System (INIS)

Hua, T.Q.

1986-01-01

Experiments were performed to investigate the coupling between eddy currents and deflection in cantilevered beams in longitudinal and transverse magnetic fields. This coupling effect reduces the current, deflection, and material stress to levels far less severe than would be predicted if coupling is disregarded. The experiments were conducted using the FELIX (Fusion ELectromagnetic Induction experiment) facility at the Argonne National Laboratory. The beams, which provide a simple model for the limiter blades in a tokamak fusion reactor, are subjected to crossed time-varying and constant magnetic fields. The time-varying field simulates the decaying field during a plasma disruption and the constant field models the toroidal field. Several test pieces are employed to allow variations in thicknesses and mechanical and electrical properties. Various magnetic field levels and decay time constants of time-varying are used to study the extent of the coupling from weak to strong coupling. The ratios of constant field to time-varying field are kept in the range from 10:1 to 20:1 as would be appropriate to tokamak limiters. Major parameters measured as functions of time are beam deflection, measured with an electro-optical device; total circulating current, measured with a Rogowski coil; strain recorded by strain gauges; and magnetic fields measured with Hall probes

Adaptable Analytical Vistas Illumine a Touchstone: Langston Hughes as Minor Author/Poet

2013-12-01

Full Text Available The authentic association of spontaneity, as a spur or basis for artistic expression, with the vaunted notion of autonomy in literary creationis nowhere more clearly established than in the work of theorists Gilles Deleuze and Felix Guattari as they, inter-alia, explicate the unique literary repertoire bestowed upon the world by Franz Kafka. In their acclaimed works: Kafka: Toward a Minor Literature and Anti-Oedipus: Capitalism and Schizophrenia,they offered to literary theory the fascinating and analytically productive constructs of deterritorialization and anti-Oedipus in the context of a compelling portraiture of the ways in which various institutionalized relationships subtly prescribe and reinforce inequity in society’s power mechanics that tendentiously impact, among other realities, the nature and quality of literary products. They offered, in the process, a refreshing definition of minor literature that unequivocally restores to literature its distinctive place and role in the amalgamated adjudications of society’s intergroup dissensions. In this regard, the present paper subscribes to the idea that spontaneity equaled the intrinsic and immutable desire of the gifted literary mind of African-American author/poet Langston Hughes to reach expressivity in accordance, strictly, with his unalloyed literary vision and thus made autonomy the inevitable upshot of his inspiration and practice.

Passive, Silent and Revolutionary: The 'Arab Spring' Revisited.

Science.gov (United States)

Brownlee, Billie Jeanne; Ghiabi, Maziyar

2016-01-01

To counter the trend toward mechanization of research and aridity of critical analysis, this article makes a case for an interdisciplinary quest. To borrow Felix Guattari and Gilles Deleuze's phrase, we are convinced that 'everything is political, but every politics is simultaneously a macropolitics and a micropolitics.' With an eye to open-ended research questions, this article attempts to build a body of theoretical, political and anthropological considerations, which, it is hoped, could function as a case of enquiry into the mechanics of power, revolt and revolution. The objective is to draw comparative and phenomenological lines between the events of the 2011 'Arab Spring,' in its local ecologies of protest, with its global reverberations as materialized in the slogans, acts and ideals of Greek and Spanish Indignados and the UK and US occupy movements. In order to do so, it proposes to clarify terminological ambiguities and to bring into the analytical scenario new subjects, new means and new connections. The article resolves to lay the ground for a scholarship of silence, by which the set of unheard voices, hidden actions and defiant tactics of the ordinary, through extraordinary people, find place in the interpretation of phenomena such as revolts and revolutions.

Full Text Available Through a process-oriented analysis of the participatory art project The Hill this article explores the relevance of participatory art projects for the development of AESD – Art Education for Sustainable Development. Inspired by Felix Guattari’s Three Ecologies (2008 the analysis moves through three sub-studies delving into three different aspects of the project. Each sub-study adopts two overlapping analytical ‘lenses’: The lens of a contemporary art form (performance art, community art, and site-specific art and the lens of a related theoretical concept (subjectivation, togetherness, environment. The aim is to propose art educational ideas and strategies that stimulate students to challenge the current political, economic and environmental situation. Central questions addressed by the article are: How can educators use contemporary artistic strategies to challenge essentialist and opportunistic self-understandings? What is the potential for participatory art forms to explore alternative and more sustainable conceptions of human subjectivity? How can art education work in favour of a sense of interconnectedness between the individual, the social and the environmental dimensions of being? In conclusion, the article proposes art education as a symbolic place for carrying out art-inspired experiments with how to live our lives in more sustainable ways.

Andean tectonics: Implications for Satellite Geodesy

Allenby, R. J.

1984-01-01

Current knowledge and theories of large scale Andean tectonics as they relate to site planning for the NASA Crustal Dynamics Program's proposed high precision geodetic measurements of relative motions between the Nazca and South American plates are summarized. The Nazca Plate and its eastern margin, the Peru-Chile Trench, is considered a prototype plate marked by rapid motion, strong seismicity and well defined boundaries. Tectonic activity across the Andes results from the Nazca Plate subducting under the South American plate in a series of discrete platelets with different widths and dip angles. This in turn, is reflected in the tectonic complexity of the Andes which are a multitutde of orogenic belts superimposed on each other since the Precambrian. Sites for Crustal Dynamics Program measurements are being located to investigate both interplate and extraplate motions. Observing operations have already been initiated at Arequipa, Peru and Easter Island, Santiago and Cerro Tololo, Chile. Sites under consideration include Iquique, Chile; Oruro and Santa Cruz, Bolivia; Cuzco, Lima, Huancayo and Bayovar, Peru; and Quito and the Galapagos Islands, Ecuador. Based on scientific considerations, Santa Cruz, Huancayo (or Lima), Quito and the Galapagos Islands should be replaced by Isla San Felix, Chile; Brazilia or Petrolina, Brazil; and Guayaquil, Ecuador. If resources permit, additional important sites would be Buenaventura and Villavicencio or Puerto La Concordia, Colombia; and Mendoza and Cordoba, Argentina.

Detection and spectral measurements of coherent synchrotron radiation at FLASH

Behrens, Christopher

2010-02-01

The operation of high-gain free-electron laser (FEL) underlies tremendous demands on high quality electron beams with high peak currents. At the Free-Electron-Laser in Hamburg (FLASH), two magnetic bunch compressors are used to compress the electron bunches longitudinally. In the bunch compressor magnets, these short electron bunches generate coherent synchrotron radiation (CSR). This CSR contains information on the longitudinal bunch profile, which is relevant for driving an FEL. In order to investigate coherent synchrotron radiation at the second bunch compressor BC3 at FLASH, a new setup behind the last dipole was installed. For the detection of coherent synchrotron radiation, which is emitted in the infrared regime, pyroelectric detectors were used. These pyroelectric detectors have been calibrated at the free-electron laser FELIX in the wavelength range from 5 μm to 110 μm. For characterisation of the emitted radiation, a transverse scanning device was used to measure the transverse intensity distribution. Various transmission filters were used to obtain additional information about the spectral content. In order to get spectral information with high resolution over a wide wavelength range, a rotating mirror spectrometer using reflective blazed gratings was installed. Using this spectrometer, the first spectral measurements of coherent synchrotron radiation at FLASH in a wavelength range from 10 μm to 160 μm were done. (orig.)

This coexistence is known as overlap syndrome and is the result of chance rather than a pathophysiological link. Although there are claims of a very high incidence of OSAS in COPD patients, recent studies report that it is similar to the general population. Overlap patients present sleep-disordered breathing associated to upper and lower airway obstruction and a reduction in respiratory drive. These patients present unique characteristics, which set them apart from either COPD or OSAS patients. COPD and OSAS are independent risk factors for cardiovascular events and their coexistence in overlap syndrome probably increases this risk. The mechanisms underlying cardiovascular risk are still unclear, but may involve systemic inflammation, endothelial dysfunction, and tonic elevation of sympathetic neural activity. The treatment of choice for overlap syndrome in stable patients is CPAP with supplemental oxygen for correction of upper airway obstructive episodes and hypoxemia during sleep.Keywords: chronic obstructive pulmonary disease, obstructive sleep apnea syndrome, overlap syndrome, sleep, cardiovascular disease

Among the Porifera, symbiosis with Symbiodinium spp. (i.e., zooxanthellae) is largely restricted to members of the family Clionaidae. We surveyed the diversity of zooxanthellae associated with sponges from the Caribbean and greater Indo-Pacific regions using chloroplast large subunit (cp23S) domain V sequences. We provide the first report of Clade C Symbiodinium harbored by a sponge (Cliona caesia), and the first report of Clade A Symbiodinium from an Indo-Pacific sponge (C. jullieni). Clade A zooxanthellae were also identified in sponges from the Caribbean, which has been reported previously. Sponges that we examined from the Florida Keys all harbored Clade G Symbiodinium as did C. orientalis from the Indo-Pacific, which also supports earlier work with sponges. Two distinct Clade G lineages were identified in our phylogenetic analysis; Symbiodinium extracted from clionaid sponges formed a monophyletic group sister to Symbiodinium found in foraminiferans. Truncated and 'normal' length variants of 23S rDNA sequences were detected simultaneously in all three morphotypes of C. varians providing the first evidence of chloroplast-based heteroplasmy in a sponge. None of the other sponge species examined showed evidence of heteroplasmy. As in previous work, length variation in cp23S domain V sequences was found to correspond in a highly precise manner to finer resolution of phylogenetic topology among Symbiodinium clades. On a global scale, existing data indicate that members of the family Clionaidae that host zooxanthellae can form symbiotic associations with at least four Symbiodinium clades. The majority of sponge hosts appear to harbor only one cladal type of symbiont, but some species can harbor more than one clade of zooxanthellae concurrently. The observed differences in the number of partners harbored by sponges raise important questions about the degree of coevolutionary integration and specificity of these symbioses. Although our sample sizes are small, we

Magnetic resonance and porous materials

International Nuclear Information System (INIS)

McDonald, P.; Strange, J.

1998-01-01

Mention the words magnetic resonance to your medical advisor and he or she will immediately think of a multi-million pound scanner that peers deep into the brain. A chemist, on the other hand, will imagine a machine that costs several hundred thousand pounds and produces high-resolution spectra for chemical analysis. Food technologists will probably think of a bench-top instrument for determining moisture content, while an oil prospector will envisage a device that can be operated several kilometres down an oil well. To a physicist the term is more likely to conjure up a mental picture of nuclear spins precessing in a magnetic field. These examples illustrate the diverse aspects of a phenomenon discovered by physicists over 50 years ago. Electron spin resonance was first discovered by Russian scientists, and nuclear magnetic resonance was discovered in the US shortly afterwards by Ed Purcell at Harvard University and Felix Bloch at Stanford University. Today, nuclear magnetic resonance (NMR) is the most widely used technique. Modern NMR machines are making it possible to probe microstructure and molecular movement in materials as diverse as polymers, cements, rocks, soil and foods. NMR allows the distribution of different components in a material to be determined with a resolution approaching 1μm, although the signal can be sensitive to even smaller lengthscales. In this article the authors describe how physicists are still developing magnetic resonance to exploit a range of new applications. (UK)

Energy in a dialog. The challenges facing Germany's power industry as a result of the energy turnaround

The challenges posed by the energy turnaround in Germany to the power industry and the national economy after the Fukushima events were the topic of the ''Energy in a Dialog'' meeting organized by the Deutsches Atomforum in Berlin on December 14, 2011. Dr. Ralf Gueldner, President of the Deutsches Atomforum, opened the conference by drawing attention to the real purposes of the energy turnaround, namely to prevent severe climate changes and, thus, also carbon emissions. Both nationally in Germany and worldwide, nuclear power made major contributions to achieving these goals. Referring to developments in many neighboring countries, he underlined that opting out of the use of nuclear power in Germany was not tantamount to the end of nuclear power. Reality in energy policy had to be accepted, however, namely that nuclear power played, and would go on playing, an important role in Europe. Other contributions by Dr. Juergen Grossmann (Chief Executive Officer of RWE AG), Stefan Kohler (Chairman of the Board of Management of the German Energy Agency - dena), and Prof.Dr. Felix Muesgens (Brandenburg Technical University of Cottbus, Chair of Power Economics) dealt with political and other boundary conditions required for the energy turnaround, and with the consequences and burdens on the power industry and the national economy. A final panel discussion chaired by Henning Krumrey (Wirtschaftswoche) was attended by F. Muesgens and Prof. Dr. Hans-Werner Sinn (President of the Munich-based Info Institute) and Prof. Dr. Michael Huether (German Business Institute). (orig.)

Recent years have been shaped by the introduction of programme-oriented funding. In 2004, we were able once again to focus on the real goal of the GSF, the performance of excellent research. The effects of fine particles, for example, are at the centre of public interest. This topic is not only of great importance for health, it also has a wide-reaching economic significance; we have only to think of filters for diesel engines. The GSF was involved in many scientific successes. For example, the results on the economic costs of smoking received considerable attention from both the general public and the scientific world. GSF scientists were involved in the decoding of the chicken genome and the discovery of a Parkinson gene. Together with university and other research organisations, they founded a Virtual Institute on Biotic Interactions, and took part in an international project on the development of combination vaccines against HIV. The setting up of the GSF 'glass laboratory', which was created with substantial support form the Helmholtz Association, is particularly worthy of mention. GSF scientists have been awarded various prizes, for example the Felix Wankel Prize awarded to Professor Jean-Marie Buerstedde. The Bavarian Advancement of Women Prize 2004, which distinguished exemplary initiatives in the area of family and women's advancement, was a special honour. Professor Magdalena Goetz was appointed Director of the Institute for Stem Cell Research. (orig.)

Lung function parameters and comorbidities of the patient, as well as the extent and distribution of the emphysema are factors to be considered when choosing the patient and the intervention. Endoscopic bronchial valve placement with complete occlusion of one lobe in patients with heterogeneous emphysema is the preferred technique because of its reversibility. The presence of high interlobar collateral ventilation will hinder successful treatment; therefore, endoscopic coil placement, polymeric lung volume reduction, or bronchoscopic thermal vapor ablation as well as lung volume reduction surgery can be used for treating patients with incomplete fissures. The effect of endoscopic lung volume reduction in patients with a homogeneous distribution of emphysema is still unclear and this subgroup should be treated only in clinical trials. Precise patient selection is necessary for interventions and to improve the outcome and reduce the risk and possible complications. Therefore, the patients should be discussed in a multidisciplinary approach prior to determining the most appropriate treatment for lung volume reduction.

This paper reports on two case studies making use of a digital simulator to investigate the maneuvering motions of ships in canals with shallow and restricted waters. The first case study corresponds to a maneuvering analysis conducted for the Port of Rio Grande (RS - Brazil), whose aim was to assess the potential impact upon maneuvers of the presence of a large offshore platform (the PETROBRAS P-53) which is to remain docked for several months at the Port to complete its construction. The second study made use of the simulator to evaluate the maneuvering conditions along the approach route and maneuvering basin of the Port of Ponta do Felix (PR - Brazil). The simulator includes a complete mathematical model of the ship dynamics in the horizontal plane when subjected to wind and current forces. It also comprises detailed models for the action of thrusters and propellers, both fixed and azimuth, employed to control maneuvers and dynamically position ships, as well as rudders and tugboats. He models used by the simulator allow for the effects of shallow and restricted waters, including the increase in resistance and lateral forces, increase in additional mass and the appearance of lateral and vertical suction (squatting). The simulator is implemented via an interactive interface through which the user is able to apply control actions (rudder angle, main engine, thrusters and tugboats) in real time during maneuvers, thereby reproducing to some extent the action of a pilot.

Znamenny scale – fait accompli?

Full Text Available The author addresses one of the most sensitive topics of Znamenny chant: its scale. He tries to restore the “burned bridges” between ideographic and staff-notation of the Chant as he redefines and essentially generalizes the concept of scale as such. The possibility to artificially construct ad hoc many scales sounding sometimes very similar to the scale suggested by the modern staff-notation is a serious argument to regard the “staff-notation based” deciphering from the 17th century (dvoeznamenniki a pure game of chance. The constructed scales, presented in the paper, are different to “keyboard diatonica” and from one another and are never subject to the unified theorizing (unified nomenclature of degrees, etc. Critically commented is the practice to uncontrollably use the trivial pitch-symbols for deciphering, which ipso facto makes the probabilistic steps of unknown scales look as the ill-founded deviations from the diatonic scale steps, which are currently in use in the common musical education. This practice hinders the chance to acknowledge the right of the remote musical culture to rest on foundations that can be formulated both positively and explicitly, all the more so, as the usage of paleographic signs looks rather consistent. The resemblances and differences between musical cultures may be treated more liberally since no scale is seen a norm. The author is based on the writings of Russian musicologist and organologist Felix Raudonikas.

Skin hyperpigmentation is the darkening of skin due to the increased production of melanin in the body. To evaluate the efficacy and safety of a botanical-based Rosa E pigmentation serum in healthy fair skin female volunteers with wrinkles, skin tone, and pigmentation. This was a single-arm, open label study conducted in healthy Indian females; 18 subjects aged 30-55, having fair Caucasian-like skin with at least 2 dark skin pigments with facial wrinkles diagnosed by dermatologist were selected. Rosa E pigmentation serum was applied twice a day for 84 days. Effect was evaluated by (i) instrumental technique (spectrophotometer ® 2600D), (ii) clinically by dermatologist regarding product efficacy (skin tone, antiwrinkle, pigmentation), and (iii) volunteers self-evaluation. The L* value of spectrophotometer reading represents lightness in the skin pigment. Reduction in the pigment was reported from day 14, with significant reductions observed till day 84 compared with baseline. Significant (P < .0001) skin pigmentation lightening was seen on day 14 (1.11) vastly improving on day 84 (1.94) based on photographic assessments. The significant reduction in skin pigment was 76.85%, Felix von Luschan skin color score was 30.24% (P < .0001) with a 7.38-fold reduction in skin tone and 57% reduction in facial wrinkles at day 84 from baseline. Rosa E pigmentation serum was found safe and effective in significant reduction in skin pigments, improvement of skin tone, and antiwrinkle properties instrumentally, clinically, and self-evaluation by volunteers. In these evaluations, best results were seen the longer the Rosa E was used. © 2017 Wiley Periodicals, Inc.

The first gas-phase infrared spectra of two isolated astronomically relevant and large polycyclic aromatic hydrocarbon (PAH) cations—diindenoperylene (DIP) and dicoronylene (DC)—in the 530–1800 cm‑1 (18.9‑5.6 μm) range—are presented. Vibrational band positions are determined for comparison to the aromatic infrared bands. The spectra are obtained via infrared multiphoton dissociation spectroscopy of ions stored in a quadrupole ion trap using the intense and tunable radiation of the free electron laser for infrared experiments (FELIX). DIP+ shows its main absorption peaks at 737 (13.57), 800 (12.50), 1001 (9.99), 1070 (9.35), 1115 (8.97), 1152 (8.68), 1278 (7.83), 1420 (7.04), and 1550 (6.45) cm‑1(μm), in good agreement with density functional theory (DFT) calculations that are uniformly scaled to take anharmonicities into account. DC+ has its main absorption peaks at 853 (11.72), 876 (11.42), 1032 (9.69), 1168 (8.56), 1300 (7.69), 1427 (7.01), and 1566 (6.39) cm‑1(μm), which also agree well with the scaled DFT results presented here. The DIP+ and DC+ spectra are compared with the prominent infrared features observed toward NGC 7023. This results both in matches and clear deviations. Moreover, in the 11.0–14.0 μm region, specific bands can be linked to CH out-of-plane (oop) bending modes of different CH edge structures in large PAHs. The molecular origin of these findings and their astronomical relevance are discussed.

An IAEA Regional Technical Co-operation (TC) project RER/9/022 on ``Environmental Restoration`` for central and eastern Europe and the former USSR was launched in 1992 and concluded at the end of 1996. The first phase of this project had the primary purpose of identifying and characterizing radioactively contaminated sites in the region, including evaluation of doses to the general public and other environmental impacts. The main result of this phase of the project were published in IAEA-TECDOC-865. A new 1995-1996 phase of the project focused on the radioactive contamination of uranium mining and milling sites and the development of plans for environmental restoration of these sites. While the 1993-1994 phase aimed at attracting the attention of Member States in the region to a long neglected problem, the second phase served as a stimulus to initiate concrete planning activities that would lead to corrective actions in highly contaminated areas in those countries. As a consequence, the project emphasis shifted from scientific discussions to the identification of responsibilities, planning activities, and the assessment of existing and required resources for the eventual implementation of restoration plans. The 1995-1996 phase of the project consisted of a planning meeting and three workshops that addressed different topical themes. The papers compiled in this publication were presented at the last workshop, held in Felix, Romania, 4-8 November 1996. They summarize national situations in environmental contamination as of the end of 1996 and ongoing or planned actions for remediation. Refs, figs, tabs.

Epistemology as Politics and the Double-bind of Border Thinking: Lévi-Strauss, Deleuze and Guattari, Mignolo

Directory of Open Access Journals (Sweden)

Timothy Nicholas Laurie

2012-11-01

Full Text Available This paper examines Gilles Deleuze and Felix Guattari’s theories of writing and the State in Anti-Oedipus and A Thousand Plateaus, teasing out issues of gender, primitivism and academic expertise in the authors’ claims about power and politics. While noting the benefits of politically analysing social customs and traditions, Laurie highlights the complicities between Deleuze and Guattari's theories and the assumptions embedded in their anthropological sources. He further argues that the cultural and historical speculations in Anti-Oedipus cannot be divorced from the authors' privilege of philosophy as a uniquely European creative space. Seeking an alternative perspective on cultural translation, the paper turns to Walter Mignolo’s study of the 'book' in Spanish-Amerindian colonial encounters. Foregrounding the critical value of philology for ‘de-colonising’ theory, Mignolo argues that Eurocentric cultural comparisons serve to legitimate particular ways of knowing within contested fields of representation. However, in both Deleuze and Guattari and Mignolo, the paper questions the gender dynamics of writing practices implicitly articulated in meta-narratives about the State and/or colonialism. Laurie suggests that these authors frequently remain oblivious to the role of women in the historical contexts examined, and that understanding political dynamics within cultural groups requires questioning the privilege of writing itself, both in and outside the academy. While sympathetic to the role of political philosophy in negotiating complex historical issues, this paper also advocates a rethinking of the subordinate place attributed to anthropological and historical research practices in the theoretical exegeses of Deleuze, Guattari and Mignolo.

Maoism, Violence and Mass Murders: The Long Chinese Civil War and its Consequences

Directory of Open Access Journals (Sweden)

Felix Wemheuer

2014-12-01

Full Text Available In 1970s, many Western leftist intellectuals considered Maoism as a less violent alternative to Stalinist Socialism. After Soviet and Chinese party archives became assessable in the 1990s, this perception seems to be dated. Felix Wemheuer discusses the origins of »red terror« in the Chinese revolution and shows that mass killings of »enemies« were an important element of several mass campaigns and mobilization launched by the Communist Party of China between the late 1920s and early 1950s. According to official records, 710,000 people were executed during the campaign to suppress counter-revolutionaties (1950–1952. This is a higher number of victims than of Stalin’s “Great Purge” (1937–1938. The article will show how terror and mass participation were linked in the early campaigns. Mao believed in the liberating act of violence, when the masses would turn »society upside down«. Furthermore, it will work out the dialectic of promoting terror and taming the uncontrollable escalation of it. Especially, during the violent land reform in the »old liberated areas« (1946–1948, the party developed certain techniques of managing terror. The question of how the CCP leadership dealt with the problem that people are beaten to death during struggle meetings will serve as an example. Last but not least, it will be argued that »red terror« could only be understood in the context of Chinese long enduring civil war.

Angular momentum, g-value, and magnetic flux of gyration states

International Nuclear Information System (INIS)

Arunasalam, V.

1991-10-01

Two of the world's leading (Nobel laureate) physicists disagree on the definition of the orbital angular momentum L of the Landau gyration states of a spinless charged particle in a uniform external magnetic field B = B i Z . According to Richard P. Feynman (and also Frank Wilczek) L = (rxμv) = rx(p - qA/c), while Felix Bloch (and also Kerson Huang) defines it as L = rxp. We show here that Bloch's definition is the correct one since it satisfies the necessary and sufficient condition LxL = iℎ L, while Feynman's definition does not. However, as a consequence of the quantized Aharonov-Bohm magnetic flux, this canonical orbital angular momentum (surprisingly enough) takes half-odd-integral values with a zero-point gyration states of L Z = ℎ/2. Further, since the diamagnetic and the paramagnetic contributions to the magnetic moment are interdependent, the g-value of these gyration states is two and not one, again a surprising result for a spinless case. The differences between the gauge invariance in classical and quantum mechanics, Onsager's suggestion that the flux quantization might be an intrinsic property of the electromagnetic field-charged particle interaction, the possibility that the experimentally measured fundamental unit of the flux quantum need not necessarily imply the existence of ''electron pairing'' of the Bardeen-Cooper-Schrieffer superconductivity theory, and the relationship to the Dirac's angular momentum quantization condition for the magnetic monopole-charged particle composites (i.e. Schwinger's dyons), are also briefly examined from a pedestrian viewpoint

Nuevos juguetes para un etnógrafo ansioso: derroteros del registro audiovisual

Full Text Available The first generation of motion pictures expands the possibilities of the iconic and indexical qualities of photography, of figuration and contact, as it complicates the links between the image and what is depicted. This paper proposes an analysis of the audiovisual image as a result of a conglomeration of signs in a corpus of discourses ranging from early ethnographic film to more recent developments. It consolidated a challenge to the heuristic power traditionally assigned to the image and its epistemic heiress, the motion picture. The beginning of this journey could be placed at the end of the nineteenth century, a period in which a considerable number of films were produced by way of chronophotography, that had the purpose to document the lives of distant and unknown people. These were the years in which Felix-Louis Regnault, member of the Society of Anthropology of Paris, thought about motion pictures as privileged tool for studying the gestures of the human body and recorded in 1895 the first scenes of an African woman. It is also the time in which ethnography goes hand by hand with colonialism, and cinema becomes a metonymic device of apprehension of the colonized space. The main purpose of this work is to trace a path that goes from the first uses of chronophotographic devices towards current audiovisual productions. In order to do this, we will study privileged rhetorical tools for the construction of otherness in order to give an account of key moments in the relationship between image and knowledge/science.

The metallogenic role of east-west fracture zones in South America with regard to the motion of lithospheric plates (with an example from Brazil)

Kutina, J.; Carter, William D.; Lopez, F.X.

1978-01-01

The role of east-west fracture zones in South America is discussed with regard to global fracturing and the motion of lithospheric plates. A set of major NW-trending lineaments has been derived which show a tendency to be spaced equidistantly and may correspond to a set of east-west fractures in the "pre-drift" position of the South American plate. Statistical analysis of linears in the ERTS-mosaics shows that NW-fractures are also among the most important ones in the Andes region, suggesting that the above major lineaments extend into the basement of the Andes. Some of the old major fractures, trending east-west in the present orientation of South America, are discussed and their NE orientation in the pre-drift position of the plate is considered. An example of structural control of ore deposition in the Brazilian Shield is presented, using the maps of the RADAM Project. It is concluded that the small tin-bearing granitic bodies concentrated in the region of Sao Felix do Xingu in the state of Para represent upper parts of an unexposed granitoid massif which is controlled by the intersection of a major east-west fracture zone probably represents westward extension of the Patos Lineament of the easternmost part of Brazil, connected with the east-west fracture zone of the Para state through the basement of the Maranhao Basin (Sineclise do Maranhao-Piaui). It is expected that the proposed "Patos-Para Lineament" extends further westward and may similarly control, at intersections with fractures of other trends, some mineralization centers in the western part of the state of Para and in the state of Amazonas.

Political theology and eschatological war

Directory of Open Access Journals (Sweden)

Griško Miroslav

2016-01-01

Full Text Available The intent of this paper is to describe the antagonism that constitutes the eschatological position, i.e., the inseparability of eschatology from a concept of eschatological war, through 1 the political theology of Carl Schmitt, 2 Orthodox Christological anthropology and 3 the nomadology of Gilles Deleuze and Felix Guattari. Schmitt's political theology can be understood as a theory of eschatological war. The theological character of Schimtt's work entails that 'the secularisation of theological concepts' is constitutive of the eschatological concept of cosmological finitude. Moreover, Schmitt's distinction between friend and enemy, which informs his concept of politics as the 'political', aims to identify the primary antagonism of eschatological history. For Schmitt, the liberal end of history is the absolutisation of the enemy, as liberalism denies the fundamental distinction of the political, namely, liberalism maintains that war is over on the basis of its claim to immanent historical truth. From the position of Orthodox Christological anthropology, liberalism also contains a clear eschatological element. The anthropology of liberalism is consistent with the gnomic will, which, according to St. Maximus the Confessor, is the fallen definition of human freedom, i.e., freedom as choice. Freedom as the natural will, in contrast, determines the ethical mission of man as the soteriological deification of cosmos. The lines of eschatological war can be further illustrated through the work of Deleuze and Guattari as well as Heinz Von Foerster, whose concepts of diagram/ abstract machine and trivial/non-trivial machine may contribute to an understanding of how a concept of war informs the transformative cosmology which belongs to the eschatological logic of cosmic finitude and deification, theosis.

The Free-Electron Laser for Infrared Experiments (FELIX) w 1 as used to study the wavelength-resolved multiple photon photodissociation of discrete, gas phase uranyl (UO2 2 2+) complexes containing a single anionic ligand (A), with or without ligated solvent molecules (S). The uranyl antisymmetric and symmetric stretching frequencies were measured for complexes with general formula [UO2A(S)n]+, where A was either hydroxide, methoxide, or acetate; S was water, ammonia, acetone, or acetonitrile; and n = 0-3. The values for the antisymmetric stretching frequency for uranyl ligated with only an anion ([UO2A]+) were as low or lower than measurements for [UO2]2+ ligated with as many as five strong neutral donor ligands, and are comparable to solution phase values. This result was surprising because initial DFT calculations predicted values that were 30-40 cm-1 higher, consistent with intuition but not with the data. Modification of the basis sets and use of alternative functionals improved computational accuracy for the methoxide and acetate complexes, but calculated values for the hydroxide were greater than the measurement regardless of the computational method used. Attachment of a neutral donor ligand S to [UO2A]+ produced [UO2AS]+, which produced only very modest changes to the uranyl antisymmetric stretch frequency, and did not universally shift the frequency to lower values. DFT calculations for [UO2AS]+ were in accord with trends in the data, and showed that attachment of the solvent was accommodated by weakening of the U-anion bond as well as the uranyl. When uranyl frequencies were compared for [UO2AS]+ species having different solvent neutrals, values decreased with increasing neutral nucleophilicity

The Historical Origins of Spacetime

Science.gov (United States)

Walter, Scott

The idea of spacetime investigated in this chapter, with a view toward understanding its immediate sources and development, is the one formulated and proposed by Hermann Minkowski in 1908. Until recently, the principle source used to form historical narratives of Minkowski's discovery of spacetime has been Minkowski's own discovery account, outlined in the lecture he delivered in Cologne, entitled Space and time [1]. Minkowski's lecture is usually considered as a bona fide first-person narrative of lived events. According to this received view, spacetime was a natural outgrowth of Felix Klein's successful project to promote the study of geometries via their characteristic groups of transformations. Or as Minkowski expressed the same basic thought himself, the theory of relativity discovered by physicists in 1905 could just as well have been proposed by some late-nineteenth-century mathematician, by simply reflecting upon the groups of transformations that left invariant the form of the equation of a propagating light wave. Minkowski's publications and research notes provide a contrasting picture of the discovery of spacetime, in which group theory plays no direct part. In order to relate the steps of Minkowski's discovery, we begin with an account of Poincaré's theory of gravitation, where Minkowski found some of the germs of spacetime. Poincaré's geometric interpretation of the Lorentz transformation is examined, along with his reasons for not pursuing a four-dimensional vector calculus. In the second section, Minkowski's discovery and presentation of the notion of a world line in spacetime is presented. In the third and final section, Poincaré's and Minkowski's diagrammatic interpretations of the Lorentz transformation are compared.

It covers the building and the running of the laboratory during these dozen years, it studies the construction and exploitation of the 600 MeV Synchro-cyclotron and the 28 GeV Proton Synchrotron, it considers the setting up of the material and organizational infrastructure which made this possible, and it covers the reigns of four Director-Generals, Felix Bloch, Cornelis Bakker, John Adams and Victor Weisskopf. Part I describes the various aspects which together constitute the history of CERN and aims to offer a synchronic panorama year by year account of CERN's main activities. Part II deals primarily with technological achievements and scientific results and it includes the most technical chapters in the volume. Part III defines how the CERN 'system' functioned, how this science-based organization worked, how it chose, planned and concretely realized its experimental programme on the shop-floor and how it identified the equipment it would need in the long term and organized its relations with the outside world, notably the political world. The concluding Part IV brings out the specificity of CERN, to identify the ways in which it differed from other big science laboratories in the 1950's and 1960's, and to try to understand where its uniqueness and originality lay.

Capitalism, psychiatry, and schizophrenia: a critical introduction to Deleuze and Guattari's Anti-Oedipus.

Science.gov (United States)

Roberts, Marc

2007-04-01

Published in 1972, Anti-Oedipus was the first of a number of collaborative works between the French philosopher, Gilles Deleuze, and the French psychoanalyst and political activist, Felix Guattari. As the first of a two-volume body of work that bears the subtitle, Capitalism and Schizophrenia, Anti-Oedipus is, to say the least, an unconventional work that should be understood, in part, as a product of its time--created as it was among the political and revolutionary fervour engendered by the events of 'May 1968'. However, this paper will suggest that Anti-Oedipus--as a critique of psychoanalysis and the Oedipus complex, as well as being a study of the relationship between capitalism and schizophrenia--should also be understood in a less 'time-bound' fashion. In particular, the paper will examine Deleuze and Guattari's formulation of a concept of 'desire' and its employment in relation to subjectivity, time, capitalism, representation, and the radical 'therapeutic' practice that they refer to as 'schizoanalysis'. Moreover, nearly 40 years after the events of May 1968 and against possible doubts concerning the contemporary relevance of psychoanalysis, it will be suggested that psychoanalysis and the Oedipus complex are to be understood as symptomatic of a wider 'malaise' that can be discerned within psychiatry, psychotherapy, and contemporary capitalist society itself, and that it is this that forms the broader target of the book's critique. Accordingly, by providing an accessible and critical introduction to Anti-Oedipus, the paper also hopes to stimulate further discussion and research regarding both the critique and the contribution that the work can make to contemporary psychiatry, psychotherapy, and mental health nursing generally.

When attempting to interpret the history of Ca, Al-rich inclusions (CAIs) it is often difficult to distinguish between primary features inherited from the nebula and those produced during secondary processing on the parent body. We have undertaken a systematic study of CAIs from 10 CO chondrites, believed to represent a metamorphic sequence with the goal of distinguishing primary and secondary features. ALHA 77307 (3.0), Colony (3.0), Kainsaz (3.1), Felix (3.2), ALH 82101 (3.3), Ornans (3.3), Lance (3.4), ALHA 77003 (3.5), Warrenton (3.6), and Isna (3.7) were examined by Scanning Electron Microscopy (SEM) and optical microscopy. We have identified 141 CAIs within these samples, and studied in detail the petrology of 34 inclusions. The primary phases in the lower petrologic types are spinel, melilite, and hibonite. Perovskite, FeS, ilmenite, anorthite, kirschsteinite, and metallic Fe are present as minor phases. Melilite becomes less abundant in higher petrologic types and was not detected in chondrites of type 3.5 and above, confirming previous reports that this mineral easily breaks down during heating. Iron, an element that would not be expected to condense at high temperatures, has a lower abundance in spinel from low-petrologic-type meteorites than those of higher grade, and CaTiO3 is replaced by FeTiO3 in meteorites of higher petrologic type. The abundance of CAIs is similar in each meteorite. Eight inclusions have been analyzed by ion probe. The results are summarized. The results obtained to date show that CAIs in CO meteorites, like those from other meteorite classes, contain Mg* and that Mg in some inclusions has been redistributed.

To our knowledge, there is no data on the epidemiology of patients hospitalized in intensive care unit (ICU) after a stay in Madagascar or other low-income countries. It is possible that such data may improve transfer delays and care quality for these patients. In a retrospective study, we reviewed the charts of all patients admitted to ICU of the Reunion Island Felix Guyon University Hospital from January 2011 through July 2013. We identified all patients who had stayed in Madagascar during the 6 months prior to ICU admission. Of 1842 ICU patients, 62 (3.4%) had stayed in Madagascar during the 6 months prior to ICU admission. Patients were 76% male and the median age was 60.5 (48.25-64.75) years; patients were more frequently residents of Madagascar than travellers (56.5%). In most cases, patients were not hospitalized or given antibiotics in Madagascar. The most frequent causes of hospitalization were infections including malaria (21%) and lower respiratory infection (11%). Carriage and infection with multidrug resistant (MDR) bacteria on ICU admission were frequent (37% and 9.7%, respectively). The mortality rate in ICU was 21%, and severity acute physiological Score II was 53.5 (37-68). Patients admitted to ICU after a stay to Madagascar are mainly elderly patients with chronic illnesses, and often foreign residents. The admission causes are specific of the country like malaria, or specific to the population concerned such as cardiovascular accidents that could be prevented. © International Society of Travel Medicine, 2016.

The Chartis system has proven to be useful for determining whether CV is present or absent, but this system can also erroneously indicate the absence of CV, which can lead to BLVR failure. Here, we describe low-flow Chartis phenotype in the target lobe resulted in difficult judgment of existence of CV. Consequently, BLVR with EBVs implanted into the right upper bronchus failed to reduce lung volume or induce atelectasis. Inserting another EBV into the right middle bronchus blocked the latent CV, which led to significant lung volume reduction in the right upper lobe (RUL and right middle lobe (RML and to improve the pulmonary function, 6-min walking distance, and St George respiratory questionnaire scores over a 2-week follow-up period. Low flow in the target lobe is a unique Chartis phenotype and represents the uncertainty of CV, which is a risk factor for the failure of BLVR using EBVs. Clinicians should be aware of this possibility and might be able to resolve the problem by blocking the RUL and RML between which the CV occurs.

The Florey turns 50.

The origins of the Howard Florey Laboratories of Experimental Physiology, Department of Physiology, The University of Melbourne, are tied to the ground-breaking clinical work of Derek A Denton in 1947 and to the investigations of the initial scientific team into the control of salt and water balance in health and disease over the period 1947-1963 were Professor RD Wright, Drs JR Goding, IR McDonald, John P Coghlan, E Marelyn Wintour and John R Blair-West. An Act of Parliament in 1971 by the Victorian State Government formally established the Institute named after Howard Florey, the Australian Nobel Prize winner who isolated penicillin. The Howard Florey Laboratories/Institute quickly became an international leader in the scientific areas of the physiological control of body fluids and electrolyte balance, especially sodium regulation and the regulation of the secretion of aldosterone, the adrenal salt-retaining hormone; the micro measurement of hormones, in particular steroids and peptides; instinctive ingestive behaviour; fetal fluid regulation; hybridization histochemistry, and the hormone relaxin. Subsequently, the senior staff included, inter alia, Bruce Scoggins, Richard Weisinger, John McDougall, Brian Oldfield, Michael McKinley, Robin McAllen, Hugh Niall, Geoff Tregear and Felix Beck. During the 1990s, an explosion occurred in neuroscience and, in 1997, the Board made the strategic decision to change the focus of the Institute to brain disorders. From 1997 to 2007, Fred Mendelsohn steered the Florey to become one of Australia's premier brain research institutes and, under the current director (the eminent clinician and neuroscientist Geoffrey Donnan), this reputation has been further enhanced. © 2014 Wiley Publishing Asia Pty Ltd.

The Incidence of the Corporate Income Tax on Wages: Evidence from Canadian Provinces

Directory of Open Access Journals (Sweden)

Kenneth J. McKenzie

2017-04-01

Full Text Available Corporate income tax (CIT incidence is an important and contentious issue in tax policy discussions. Much of the focus in the recent literature and in policy discussions concerns the allocation of the burden of the CIT between owners of capital and labour. Since income from capital tends to be concentrated with wealthier individuals, if the burden of the CIT falls largely on capital it increases the tax system’s progressivity. On the other hand, if the tax is borne mostly by labour through lower wages, the CIT is less progressive. Despite the importance of this issue in policy discussions, empirical evidence is quite limited and the results are mixed; there is a particular dearth of empirical research on the incidence of corporate taxes in a Canadian setting. According to theoretical open economy general equilibrium models, the burden of the CIT may partly, and possibly largely, fall on labour. In these models, an increase in the CIT reduces the return to capital, causing capital to leave the jurisdiction, which lowers the marginal product of labour and ultimately wages. Thus, the CIT can have a negative indirect effect on wages through its impact on labour productivity by way of its impact on capital. However, the magnitude of this effect depends critically on several modelling assumptions and parameter values related to the size of the country, the degree of capital mobility, the nature of competition in the output market, etc. An emerging empirical literature investigates the effects of CIT on wages by way of this indirect transmission mechanism. Empirical studies in this vein include Hassett and Mathur (2006, 2015 for a cross-section of countries; Desai, Foley and Hines (2007 and Felix (2007, 2009 for the U.S. They all find evidence in support of the relevance of the indirect channel using national aggregate data. Other studies, such as Carroll (2009 and Felix (2009 for the U.S., examine corporate tax incidence at the subnational level

Many developing countries have shown interest in embracing telemedicine and incorporating it into their healthcare systems. In 2000, the U.S. Army Yuma Proving Ground (YPG) initiated a program to assist the Republic of Panama in establishing a demonstration Panamanian rural telemedicine program. YPG engaged the Arizona Telemedicine Program (ATP) to participate in the development and implementation of the program. The ATP recommended adoption of a "top-down" strategy for creating the program. Early buy-in of the Panamanian Ministry of Health and academic leaders was regarded as critical to the achievement of long-term success. High-level meetings with the Minister of Health and the Rectors (i.e., Presidents) of the national universities gained early program support. A telemedicine demonstration project was established on a mountainous Indian reservation 230 miles west of Panama City. Today, three rural telemedicine clinics are linked to a regional Ministry of Health hospital for teleconsultations. Real-time bidirectional videoconferencing utilizes videophones connected over Internet protocol networks at a data rate of 768 kilobits per second to the San Felix Hospital. Telepediatrics, tele-obstetrics, telepulmonology, teledermatology, and tele-emergency medicine services became available. Telemedicine services were provided to the three sites for a total of 1,013 cases, with numbers of cases increasing each year. These three demonstration sites remained in operation after discontinuation of the U.S. involvement in September 2009 and serve as a model program for other telemedicine initiatives in Panama. Access to the assets of a partner-nation was invaluable in the establishment of the first model telemedicine demonstration program in Panama. After 3 years, the Panamanian Telemedicine and Telehealth Program (PTTP) became self-sufficient. The successful achievement of sustainability of the PTTP after disengagement by the United States fits the Latifi-Weinstein model

CARACALLA AND DACIA. IMPERIAL VISIT, A REALITY OR ONLY RUMOUR?

Directory of Open Access Journals (Sweden)

Coriolan Horatiu Opreanu

2015-06-01

Full Text Available The author is challenging the Romanian historiography’s interpretation concerning the visit in 213 of the emperor Caracalla in Dacia, until to the northern frontier at Porolissum, where three inscriptions with identical text were considered as the building inscriptions of the stone fortifications of the fort from Pomet Hill. He is mentioning the new inscriptions from different part of the Roman Empire that offer today a better knowledge of the emperor’s actions and journeys during year 213. The conclusion is that he travelled to Orient after October 213 when defeated the Alamanns over the border of Raetia, along the Danube frontier visiting military bases. The journey was probably on the same route as he already done in 202 with his father, but in the other direction, returning from Orient. That time is possible Septimius Severus, Caracalla and Geta were in Dacia, at Drobeta, Tibiscum and Ulpia Traiana Sarmizegetusa, as several inscriptions attest. For this reason, it is possible that in 213 Caracalla stopped for a short period at Drobeta and maybe went to Tibiscum to pray in the temple of Apollo. However, continuing the trip to Porolissum is impossible to imagine, the time being too short, as he arrived at Nicomedia on the 17th of December 213. At the end of the article, the author rejects the theory of any connection between the tile-stamps of the seventh legion Gemina Felix from Leon and those of the third legion Gallica found at Porolissum with Caracalla’s journey. Furthermore, the author also dismisses the idea that these vexillations were taken to Dacia to replace Dacian vexillations involved in the eastern expedition of Caracalla, as there is neither no any positive evidence nor other evidence for similar examples in the history of the Roman military expeditions (e.g., Trajan’s Parthian war.

Tropical Cyclone Induced Air-Sea Interactions Over Oceanic Fronts

Science.gov (United States)

Shay, L. K.

2012-12-01

Recent severe tropical cyclones underscore the inherent importance of warm background ocean fronts and their interactions with the atmospheric boundary layer. Central to the question of heat and moisture fluxes, the amount of heat available to the tropical cyclone is predicated by the initial mixed layer depth and strength of the stratification that essentially set the level of entrainment mixing at the base of the mixed layer. In oceanic regimes where the ocean mixed layers are thin, shear-induced mixing tends to cool the upper ocean to form cold wakes which reduces the air-sea fluxes. This is an example of negative feedback. By contrast, in regimes where the ocean mixed layers are deep (usually along the western part of the gyres), warm water advection by the nearly steady currents reduces the levels of turbulent mixing by shear instabilities. As these strong near-inertial shears are arrested, more heat and moisture transfers are available through the enthalpy fluxes (typically 1 to 1.5 kW m-2) into the hurricane boundary layer. When tropical cyclones move into favorable or neutral atmospheric conditions, tropical cyclones have a tendency to rapidly intensify as observed over the Gulf of Mexico during Isidore and Lili in 2002, Katrina, Rita and Wilma in 2005, Dean and Felix in 2007 in the Caribbean Sea, and Earl in 2010 just north of the Caribbean Islands. To predict these tropical cyclone deepening (as well as weakening) cycles, coupled models must have ocean models with realistic ocean conditions and accurate air-sea and vertical mixing parameterizations. Thus, to constrain these models, having complete 3-D ocean profiles juxtaposed with atmospheric profiler measurements prior, during and subsequent to passage is an absolute necessity framed within regional scale satellite derived fields.

Drague et cruising

Full Text Available Dans la culture homosexuelle masculine, drague et cruising sont des termes équivalents. Ils désignent la quête d’un ou de plusieurs partenaires occasionnels et anonymes. Analyser leurs référents métaphoriques respectifs offre un éclairage particulier, à la fois phénoménologique et géographique, pour une compréhension nuancée des types de pratique et d’expérience qu’ils recouvrent. Cet article pose l’hypothèse d’une distinction entre deux figures, le dragueur et le cruiser, et postule que cette distinction se tient essentiellement dans l’opposition que Gilles Deleuze et Félix Guattari établissent entre ‘espace strié’ et ‘espace lisse’. L’essai de théorisation qui en découle est une manière de comprendre ce qui, entre sexualisation de l’espace et érotisation d’un mouvement exploratoire, fait fonctionner le script de la drague.In French gay culture, drague means cruising: looking for anonymous and 
casual sexual partners. This paper, by respectively examining the 
metaphorical underpinnings of both words, French and English, throws 
doubt on the validity of this translation. Through a phenomenological 
and geographical perspective, it attempts to give a nuanced examination 
of the practice and experience that each word conceals. The aim is to 
identify two figures embodied in a same person: the dragueur and the 
cruiser. I will argue that the distinction mainly rests on the 
opposition that Gilles Deleuze and Felix Guattari establish between ‘striated space’ and ‘smooth space’. The concluding theorical 
discussion is an attempt to understand what, in the tension between sexualization of space and eroticization of movement, guides the scripts of drague and cruising.

From rational creatures to the rational Creator: ancient and patristic analogies of the “fine-tuning” argument

Directory of Open Access Journals (Sweden)

Alexey Fokin

2017-12-01

Full Text Available In this article the author deals with the proofs of the existence of God, based on the fact of the presence of rational beings in the world. These proofs can be found in Greek and Roman Classical philosophy and early Patristics, and can be viewed as an analogue of the modern “fine-tuning argument”. The author considers the origins and development of this argument in the Greek and Roman philosophy: in Socrates, Plato, Cicero, Sextus Empiricus, and especially the Stoics, who gave to the argument a logical form, based on the relationship between “the parts and the whole”: if the world as a whole produces and contains rational beings as its parts, it should also be rational or contain a rational principle that generates all its parts and governs them, just as human soul governs human body. The correction of this argument was proposed by Sextus Empiricus, who introduced the concept of "spermatic logoi", or rational principles, to explain the generation of the rational beings by the world, so that if the world contains the spermatic logoi of rational and living beings, then the world as a whole is also rational. The author also investigates the reception of the argument based on the existence of rational beings in the world in Latin Patristics: in Minucius Felix, Tertullian and especially Lactantius, in whom this argument has reached the climax of its development. At the same time it was shown, that the ancient argument has undergone a transformation from the postulation of the rationality of the world as a whole or its equation with God himself to a genuine proof of the existence of the one God who is the Creator both of the world and human beings, superior to the both as the all-powerful and transcendent Mind.

Full Text Available Background: In the recent past, scrub typhus (ST has been reported from different parts of India, based on Weil-Felix/enzyme-linked immunosorbent assay (ELISA/indirect immunofluorescence assay (IFA. Molecular tests are applied only by a few researchers. Aims: Evaluation of a new commercial real time polymerase chain reaction (PCR kit for molecular diagnosis of ST by comparing it with the commonly used IgM ELISA is our aim. Settings and Design: ST has been reported all over India including Puducherry and surrounding Tamil Nadu and identified as endemic for ST. This study was designed to correlate antibody detection by IgM ELISA and Orientia tsutsugamushi DNA in real time PCR. Materials and Methods: ST IgM ELISA (InBios Inc., USA was carried out for 170 consecutive patients who presented with the symptoms of acute ST during 11 months (November, 2015– September, 2016. All 77 of these patients with IgM ELISA positivity and 49 of 93 IgM ELISA negative patients were subjected to real time PCR (Geno-Sen's ST real time PCR, Himachal Pradesh, India. Statistical Analysis: Statistical analysis for clinical and laboratory results was performed using IBM SPSS Statistics 17 for Windows (SPSS Inc., Chicago, USA. Chi-square test with Yates correction (Fisher's test was employed for a small number of samples. Results and Conclusion: Among 77 suspected cases of acute ST with IgM ELISA positivity and 49 IgM negative patients, 42 and 7 were positive, respectively, for O. tsutsugamushi 56-kDa type-specific gene in real time PCR kit. Until ST IFA, the gold standard diagnostic test, is properly validated in India, diagnosis of acute ST will depend on both ELISA and quantitative PCR.

Tsutsugamushi Disease (Scrub Typhus) Meningoencephalitis in North Eastern India: A Prospective Study.

2015-01-01

Scrub typhus is rampant in northern, eastern, and southern India. Central nervous system involvement in the form of meningitis or meningoencephalitis is common in scrub typhus. As specific laboratory methods remain inadequate or inaccessible in developing countries, prompt diagnosis is often difficult. The aim of this study was to characterize neurological complications in scrub typhus from northeastern region of India. We did a prospective study of scrub meningoencephalitis at North Eastern Indira Gandhi Regional Institute of Medical Sciences among patients admitted to hospital between October 2009 and November 2011. The diagnosis was made based on the clinical pictures, presence of an eschar, and a positive Weil-Felix test (WFT) with a titer of >1:160 and if required a positive scrub IgM enzyme-linked immunosorbent assay. Lumbar puncture was performed in patients with headache, nuchal rigidity, altered sensorium or cranial nerve deficits, and magnetic resonance imaging (MRI) brain performed if needed. Twenty-three patients of scrub typhus meningitis that were serologically confirmed were included in the study. There were 13 males and 10 females. Fever ≥1 week was the most common manifestation (39.1%). Interestingly, none had an eschar. Median cerebrospinal fluid (CSF) cell count, lymphocyte percentage, CSF protein, CSF glucose/blood glucose, CSF ADA were 17 cells/μL, 90%, 86 mg/dL, 0.6605 and 3.6 U/mL, respectively. All patients were treated with doxycycline. There was no mortality in our study. Absence of Eschar does not rule out scrub typhus. Clinical features and CSF findings can mimic tuberculous meningitis so misdiagnosis may lead to unwarranted prolonged empirical antituberculous therapy in cases of lymphocytic meningoencephalitis. Delay in treatment can be potentially fatal. WFT still serves as a useful and affordable diagnostic tool for this disease in resource-poor countries.

Full Text Available An outstanding British architect Edward Blore (1787–1879 is the main author of project of Vorontsov’s Palace in Alupka (the Crimea, 1830–1848. In the opining of many researchers the Vorontsov’s Palace in Alupka is the best of Edward Blore’s works. Seemingly under impression of Vorontsov’s Alupka Palace, Brzhozovsky’s Palace (Shakh’s Palace. 1851–1852 was built to the project of a renowned Odessa architect Felix Gonsiorovski (1815–1891 in 2 Nadezhdinskaya (Gogol street in Odessa. Apart from Tudor elements and Castel style, these two Palaces are related yet by the fact that they both are situated on the Black Sea coast. Facades of Brzhozovsky’s Palace remind the same of a distinguished monument of architecture, historically connected with the names of British monarchs – the Hampton Court Palace. Hampton Court Palace was recognized as the acme of the English palace architecture. Splendid ensemble sprawling on the bank of the Thames River near London was initiated in 1514. The great vogue for all Gothic sprang up in St. Petersburg under the spell of Walter Scott’s (1771–1832 historic novels. The article tells also about prototypes of Tudor arch – an element which characterizes English architecture of 16th century. This form of the arch was spread to many countries from the United Kingdom. However, long before England, this form of arch was used by architects of Iran and other countries of Central Asia. Formation of Odessa’s and all Southern Region of the Ukraine architectural appearance in the XIXth century was influenced by different architectural European schools. Especially in this article is noted British influence. Consequently it seems proper to consider this process in the retrospect of the European development as a whole.
