Surface doping of nano/mesostructured materials with metal nanoparticles to promote and optimize chemi-transistor sensing performance represents the most advanced research trend in the field of solid-state chemical sensing. In spite of the promising results emerging from metal-doping of a number of nanostructured semiconductors, its applicability to silicon-based chemi-transistor sensors has been hindered so far by the difficulties in integrating the composite metal-silicon nanostructures using the complementary metal-oxide-semiconductor (CMOS) technology. Here we propose a facile and effective top-down method for the high-yield fabrication of chemi-transistor sensors making use of composite porous silicon/gold nanostructures (cSiAuNs) acting as sensing gate. In particular, we investigate the integration of cSiAuNs synthesized by metal-assisted etching (MAE), using gold nanoparticles (NPs) as catalyst, in solid-state junction-field-effect transistors (JFETs), aimed at the detection of NO2 down to 100 parts per billion (ppb). The chemi-transistor sensors, namely cSiAuJFETs, are CMOS compatible, operate at room temperature, and are reliable, sensitive, and fully recoverable for the detection of NO2 at concentrations between 100 and 500 ppb, up to 48 h of continuous operation.

A reverse bias tunable Pd- and Pt-functionalized graphene/Si heterostructure Schottky diode H2 sensor has been demonstrated. Compared to the graphene chemiresistor sensor, the chemi-diode sensor offers more than one order of magnitude higher sensitivity as the molecular adsorption induced Schottky barrier height change causes the heterojunction current to vary exponentially in reverse bias. The reverse bias operation also enables low power consumption, as well as modulation of the atomically thin graphene's Fermi level, leading to tunable sensitivity and detection of H₂ down to the sub-ppm range.

PNL is developing a method to use thiophillic microorganisms to devulcanize (biodesulfurize) the surface of ground rubber particles, which will improve the bonding and adhesion of the ground tire rubber into the virgin tire rubber matrix. The Chemi-microbial processing approach, introduced in this paper, is targeted at alleviating the waste tire problem in an environmentally conscious manner; it may also be applied to improve asphaltic materials and rubber and polymeric wastes to facilite their recycling. This paper outlines the logic and technical methods that will be used

Endoergic chemi-ionization in N-O collisions

Nielsen, S.E.; Dahler, J.S.

1979-01-01

A semiclassical theory of endoergic chemi-ionization is developed and applied to the ionizing events that occur when ground state oxygen atoms collide with nitrogen atoms in the ground and first excited states. The approach used is an adaptation and extension of earlier theories due to Bardsley, Nakamura, and Miller. The theory relates the experimental associative (AI) and Penning ionization (PI) cross sections to the following events: formation of a stable diatomic ion (AI), neutral and ionized atomic fragments (PI), or of a metastable diatomic rotational resonance (DI, delayed ionization). The heavy particle motions are treated classically in terms of adiabatic potential energy functions, while localized nonadiabatic transitions also are taken into account by using the Landau-Zener approximation. Finally, the theoretical predictions compare well with the results of Ringer and Gentry's (1978) merged beam experiments

Clinical applications of proton magnetic resonance spectroscopy of the brain; Klinische Anwendungen der Protonen-Magnetresonanzspektroskopie des Gehirns

In spite of all the scientific advances of the past few years, proton magnetic resonance spectroscopy of the brain has not attained the status of a routine examination technique with clinically accepted indications. The method should be considered as an additional option to MR imaging for inherited and acquired encephalopathic changes as well as, in future, for localization diagnosis of epilepsies. A proton magnetic resonance spectroscopic investigation without a prior intensive clinical and imaging investigation is not useful. Above all, factors influencing metabolite distribution such as for example, serum osmolability must be known. Methodological prerequisites for the clinical application of proton resonance spectroscopy are, first of all, a high stability of the chosen technique as well as a sufficiently certain quantification of metabolites and the availability of a reference group. The use of short echo times is necessary for the quantification of glutamine and the osmolyte myo-inositol. Indications for individual cases in which clinical investigations and MR topography cannot provide sufficient certainty and spectroscopy can furnish additional information are, in addition to uses in neuropediatrics, the suspicion of Alzheimer`s dementia, HIV encephalopathy in early manifestations, and unclarified depressions of consciousness accompanying liver cirrhosis.

In the present work the impact of aircraft emissions on the atmospheric composition is studied using a mesoscale chemistry transport model. To simulate the impact of aircraft exhausts several modifications on the EURAD model system have been performed. The upper boundary of the model has been extended from 100 hPa up to 10 hPa. The vertical resolution of the model has been refined especially in tropopause altitudes extending the number of model layers from 15 to 29. Additionally the initialization and the treatment of the boundary conditions has been improved by coupling the trace gas concentration fields with the individual meteorological situation. To guarantee an adequate representation of the atmospheric chemistry the chemical mechanism CHEST has been developed and implemented into the chemistry transport model. CHEST treats the most important chemical processes of the troposphere and lower stratosphere. In the frame of the present work sensitivity studies with a box model and with the threedimensional chemistry transport model have been performed to investigate the impact of aircraft emissions upon the atmosphere.

Studies were made by a merging-beams technique of the associative ionization (AI) reaction (1) Ne/sup asterisk/+Ar/sup asterisk/→NeAr + +e and the Penning ionization (PI) reactions (2) Ne/sup asterisk/+Ar/sup asterisk/→Ne+Ar + +e and (3) Ne/sup asterisk/+Ar/sup asterisk/→Ne + +Ar+e. The relative kinetic energy of the reactants was varied from 0.01 to 10 eV. The Ne/sup asterisk/ and Ar/sup asterisk/ each represents a composite of the metastable 0 P/sub 2,0/ states. There is a complication in the present investigation which arises because AI and PI occur in collisions of Ne/sup asterisk/ with ground-state Ar. Since the reactant beams consist of metastable as well as ground-state species, the measurements are composites of chemi-ionization in both the Ne/sup asterisk/--Ar/sup asterisk/ and Ne/sup asterisk/--Ar systems. Information on AI and PI for the Ne/sup asterisk/--Ar/sup asterisk/ system is obtained by subtracting from these composite measurements known contributions of the Ne/sup asterisk/--Ar system. From such information it appears that the molecular states of the reactants are different for reactions (2) and

Cosmic particle radiation may damages payload's electronics, optics, and sensors during of long-term scientific space mission especially the interplanetary ones. That is why it's extremely important to prevent failures of digital electronics, CCDs, semiconductor detectors at the times of passing through regions of enhanced charged particle fluxes. Well developed models of the Earth's radiation belts allow to predict and to protect sensitive equipment against disastrous influence of radiation due to energetic particle contained in the Van Allen belts. In the contrary interplanetary probes flying far away from our planet undergoes passages through clouds of plasma and solar cosmic rays not predictable by present models. Especially these concerns missions planned for non-ecliptic orbits. The practical approach to protect sensitive modules may be to measure the in situ particle fluxes with high time resolution and generation of alarm flags, which will switch off sensitive units of particular scientific equipment. The ChemiX (Chemical composition in X-rays) instrument is being developed by the Solar Physics Division of Polish Space Research Centre for the Interhelio-Probe interplanetary mission. Charged particle bursts can badly affect the regular measurements of X-ray spectra of solar origin. In order to detect presence of these enhanced particle fluxes the Background Particle Monitor (BPM) was developed constituting now a vital part of ChemiX. The BPM measurements of particle fluxes will assist to determine level of X-ray spectra contamination. Simultaneously BPM will measure the energy spectra of ambient particles. We present overall structure, design, technical and a scientific characteristic of BPM, particle sorts, and energy ranges to be registered. We describe nearly autonomous modular structure of BPM consisting of detector head, analogue and digital electronics modules, and of module of secondary power supply [1-3]. Detector head consists of three

Neutron irradiation at room temperature were performed on EPDM (ethylene-propylene-diene monomer) in two different nuclear reactors at different fluxes. The effect of the irradiation on the chain arrangement in the polymer, as a function of the dose is discussed. Different crystal concentrations and crystal shapes, developed by chemi-crystallisation, are obtained depending on the neutron dose. In addition the radiation damage degree in the polymer depends both on the dose and the flux level. Dynamical mechanical analysis, swelling studies, X-ray diffraction, differential thermal analysis and infrared studies were employed as experimental techniques

This work investigated the changes in the physical structure of autohydrolyzed poplar sapwood chips and the effect on the subsequent alkali liquor diffusion properties for chemi-mechanical pulping (CMP). An alkali impregnation process was conducted by using the autohydrolyzed poplar sapwood with different levels of autohydrolysis intensity. The results showed that the volume porosity, water constraint capacity, and saturated water absorption of the autohydrolyzed poplar sapwood chips increased. Also, the effective capillary cross-sectional area (ECCSA) in the radial direction and the diffusion coefficients of NaOH solution in both the radial and axial directions all increased. Autohydrolysis pretreatment enhanced the alkali liquor diffusion properties in poplar sapwood chips, and the diffusion coefficient was increased more greatly in the radial direction than that in the axial direction.

Study the pre-operative combined therapy effect in the treatment of the rectum cancer cases of the Servicio de Cirugia General 2 of the Hospital Mexico. The study covers since January of 2003 until December of 2005. It has like specific objectives to analyze the effect in the tumour stages, the sphincters preservation and the recurrence. In the conclusions, it notes that the pre-operative chemie-radiation in the rectum cancer is indicated in II and III stages, in which it has showed most advantages for the patient. It describes that the time between the end of pre-operative combined treatment and the surgery must has at least six weeks to guarantee the effect in the tumour and to reduce the treatment toxicity. It concludes besides, that the complication rate after the pre-operative combined therapy and the total meso rectum excision is approximately of 33%; however, the pelvic septic complications can reduce with an ostomy of protection. It focus that the technique of sphincters preservation has showed to be effective and secure if it does a previous selection to the patients in appropriate form. To get an suitable stages must count with trans rectum endoscopic ultrasound and a tomography of suitable quality. It concludes, also, in intervened tumours after of neo-adjuvancy they don't need free distal margins of illness higher to 2 cm.

Full Text Available The effect of microwaves on the functionalization of single-walled carbon nanotubes (SWNTs by the diazonium method was studied. The usage of a new approach led to the identification of the strength of the interaction (physical or chemical between the functional groups and the carbon nanotube surface. Moreover, the nature (chemical formula of the adsorbed/grafted functional groups was determined. According to thermogravimetric analysis coupled with mass spectrometry and Raman spectroscopy, the optimal functionalization level was reached after 5 min of reaction. Prolonged reaction times can lead to undesired reactions such as defunctionalization, solvent addition and polymerization of the grafted functions. The strength (chemi- vs physisorption of the bonds between the grafted functional groups and the SWNTs is discussed showing the occurrence of physical adsorption as a consequence of defunctionalization after 15 min of reaction under microwaves. Several chemical mechanisms of grafting could be identified, and it was possible to distinguish conditions leading to the desired chemical grafting from those leading to undesired reactions such as physisorption and polymerization.

A merging-beams technique has been used to study collisions of He*(2sup(1,3)S) with Li. The He* represents a composite of 13% He(2 1 S) and 87% He(2 3 S). Absolute and relative cross sections, Q, have been measured in a range of relative kinetic energy, W, from 150 to 1500 eV for the ion pair production (IPP) of He + + Li - , and from 0.01 to 500 eV for chemi-ionisation (CI). Information obtained for CI shows that: the Penning ionisation reaction is directed with most of the Li + scattered in the incident Li direction, the He*-Li system is attractive with a measured well depth of 0.73 eV and the value of Q for total ionisation varies as Wsup(-0.34). Similarities to the He*-He* system are also given. (author)

Functional magnetic resonance imaging (fMRI) is frequently used in the presurgical diagnostic procedure of epilepsy patients, in particular for lateralization of speech and memory and for localization of the primary motor cortex to delineate the epileptogenic lesion from eloquent brain areas. fMRI is one of the non-invasive procedures in the presurgical diagnostic process, together with medical history, seizure semiology, neurological examination, interictal and ictal EEG, structural MRI, video EEG monitoring and neuropsychology. This diagnostic sequence leads either to the decision for or against elective epilepsy surgery or to the decision to proceed with invasive diagnostic techniques (Wada test, intra-operative or extra-operative cortical stimulation). It is difficult to evaluate the contribution of the fMRI test in isolation to the validity of the entire diagnostic sequence. Complications such as memory loss and aphasia in temporal lobe resections or paresis after frontal lobe resections are rare and rarely of disastrous extent. This further complicates the evaluation of the clinical relevance of fMRI as a predictive tool. In this article studies which investigated the concordance between fMRI and other diagnostic gold standards will be presented as well as the association between presurgical fMRI and postsurgical morbidity.

Purpose: To demonstrate and document 10 years of clinical experience gathered by us with TIPSS and to discuss achievements, problems and outlook. Results: Variceal filling was widely reduced by TIPSS, and significantly reduced portal liver perfusion as assessed morphologically and rheologically. However, there was an immediate onset of compensated liver perfusion by increased arterial inflow. Total liver perfusion did not change significantly. In TIPSS portal decompression was readily achieved, the portosystemic gradient dropping from an average of 24 mm Hg to 10.5 mm Hg. In our series we could not demonstrate an increased incidence of hepatic encephalopathy during the 30-day post-TIPSS period. Early mortality was 4% and early rebleeding rate 3%. The 12-month re-intervention rate based on an invasive portography follow-up protocol was 76%, and the 24-month re-intervention rate was 90%. The definite occlusion rate was below 5%. Beyond a follow-up time span of 24-months the necessity for re-intervention dropped significantly: Less than one-third of our patients required some sort of re-intervention.

Obwohl subklinische Enthesiopathie ein gut etabliertes diagnostisches Merkmal der Psoriasisarthritis (PsA) ist, wird sie häufig übersehen, da viele Patienten asymptomatisch sind. Gäbe es klinische Hinweise auf das Vorliegen einer Enthesiopathie, würde dies den Klinikern die Möglichkeit eröffnen, eine PsA frühzeitig zu diagnostizieren. Es wurde eine monozentrische prospektive Studie mit insgesamt 90 Psoriasis-Patienten durchgeführt, um mittels Ultraschall das Vorliegen von Enthesenanomalien zu untersuchen und eine Korrelation mit dem Befall der Nägel festzustellen. Enthesenanomalien wurden bei 23 Patienten (25,5 %) gefunden, von denen 19 (82,6 %) Nagelbefall aufwiesen. Bei 4 Patienten waren die Nägel nicht betroffen. Enthesiopathie lag bei 31,1 % (19/61) der Patienten mit Onychopathie vor, von den Patienten ohne Nagelbefall litten nur 13,8 % (4/29) an Enthesiopathie (p = 0,07). Zwischen dem Target-NAPSI-Score und dem Vorliegen einer Enthesiopathie bestand eine signifikante Korrelation. Eine signifikante Korrelation bestand darüber hinaus auch zwischen dem Vorliegen einer Enthesiopathie und der Anzahl der betroffenen Nägel (p = 0,035). Klinische Belege für eine Onychopathie können der Schlüssel für die frühe Diagnose einer Enthesiopathie bei Psoriasis-Patienten sein. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

An evaluation of the importance of nuclear medicine for treatment planning purposes in radiation therapy revealed in 20.6% of the cases relevant new information due to the scans. That nevertheless the demand for nuclearmedical examinations is decreasing might be a result of an increasing alienation between nuclear medicine and referring physicians of other specialities. Therefore a reapproach of nuclear medicine with her main clinical partners is desireable which could be achieved e.g. by exchange of rotating house officers, participation in tumor conferences and consiliary statements to scan indications. (orig.) [Deutsch] Die klinische Nuklearmedizin hat sich durch die technischen und pharmakologischen Entwicklungen der letzten 15 Jahre erheblich veraendert. Eine Evaluation der Bedeutung nuklearmedizinischer Verfahren fuer die Bestrahlungsplanung in der Strahlentherapie hat in 20,6% der Faelle eine untersuchungsbedingte, planungsrelevante Information erbracht, auf die nicht verzichtet werden konnte. Dass die Nachfrage nach nuklearmedizinischen Untersuchungen in diesem Bereich trotzdem ruecklaeufig ist, duerfte Ergebnis einer zunehmenden Entfremdung der Zuweiser aus den verwandten Faechern von der Nuklearmedizin sein. Es ist deshalb eine Wiederannaeherung der Nuklearmedizin an ihre klinischen Hauptpartner wuenschenswert, die durch Austausch von Rotationsassistenten, die Beteiligung an Tumorkonferenzen und die konsiliarische Stellungnahme zu Untersuchungsindikationen erreicht werden koennte.

The exothermicity of the chemi-ionization reaction Sm + O → SmO + + e − has been re-evaluated through the combination of several experimental methods. The thermal reactivity (300–650 K) of Sm + and SmO + with a range of species measured using a selected ion flow tube-mass spectrometer apparatus is reported and provides limits for the bond strength of SmO + , 5.661 eV ≤ D 0 (Sm + -O) ≤ 6.500 eV. A more precise value is measured to be 5.72 5 ± 0.07 eV, bracketed by the observed reactivity of Sm + and SmO + with several species using a guided ion beam tandem mass spectrometer (GIBMS). Combined with the established Sm ionization energy (IE), this value indicates an exothermicity of the title reaction of 0.08 ± 0.07 eV, ∼0.2 eV smaller than previous determinations. In addition, the ionization energy of SmO has been measured by resonantly enhanced two-photon ionization and pulsed-field ionization zero kinetic energy photoelectron spectroscopy to be 5.7427 ± 0.0006 eV, significantly higher than the literature value. Combined with literature bond energies of SmO, this value indicates an exothermicity of the title reaction of 0.14 ± 0.17 eV, independent from and in agreement with the GIBMS result presented here. The evaluated thermochemistry also suggests that D 0 (SmO) = 5.83 ± 0.07 eV, consistent with but more precise than the literature values. Implications of these results for interpretation of chemical release experiments in the thermosphere are discussed

Results of quality control surveys of radioimmunological determinations of thyrotropin in newborns

Within the quality control scheme of the Deutsche Gesellschaft fuer Klinische Chemie, seven quality control surveys of thyrotropin (TSH) determinations in blood dried on filter paper have been carried out since 1980. Ninety-six screening laboratories from 12 European countries took part in these surveys. In a single survey each participant usually analysed four different samples; each of these consisted of three spots of dried blood spiked with defined amounts of thyrotropin. For the evaluations of the surveys the participants were asked to give information about their analytical results, and from these, their diagnostic classifications. The medians of the analytical results correlated well with the given thyrotropin concentrations, but the individual estimations from different laboratories varied greatly. Major discrepancies of classification were also apparent, both in the given thyrotropin concentrations and in the individual estimations. Two special collaborative studies with nine selected laboratories showed on the one hand that analysis of the largest possible part of the dried blood sample can help to optimize the precision of the results; on the other hand, considerable drawbacks related to the reagents and the methods were sometimes observed.

Peripheral neuropathies are common and diagnostically often challenging disorders. Difficulties particularly exist in lesion localization and recognition of complex spatial lesion patterns. Medical history taking, neurological examination, neurophysiological tests and nerve ultrasonography represent the gold standard in the diagnosis of peripheral nerve lesions but have known methodical limitations. The use of 3 Tesla magnetic resonance neurography (MRN) is an additional diagnostic imaging tool recently developed for the high-resolution visualization of long segments of peripheral nerves. Reasonable clinical indications for MRN are exemplarily presented. Using MRN a direct visualization and thus precise localization of focal and non-focal peripheral nerve lesions of various origins can be achieved with high spatial resolution down to the anatomical level of nerve fascicles. Using MRN large anatomical areas of the peripheral nervous system (PNS) can be covered in a single examination session, spatial nerve lesion patterns can be evaluated and the underlying causes can often be detected. The MRN is a valuable supplement to the diagnostic work-up of the PNS, especially in cases that cannot be clarified with standard diagnostic methods. Evaluation of the spatial nerve lesion pattern gives additional information on the origin of the underlying disease. Reasonable indications for MRN are the assessment of proximal nerve structures including the brachial and lumbosacral nerve plexi, the clarification of inconclusive diagnostic results, preoperative, postoperative and posttraumatic assessments, the identification of fascicular nerve lesions and the differential diagnosis of an alleged somatoform disorder.

The term ''acute abdomen'' does not describe a specific disease entity but is more a critical clinical state which incorporates very heterogeneous clinical presentations. The prognosis of any disease depends on the time frame from the onset of symptoms to the initiation of a specific therapy. For this reason there are special expectations by clinicians regarding the diagnostic assessment provided by radiology which is expected to deliver an immediate diagnosis supporting further therapeutic decisions. Along with the patient's clinical history, physical examination and blood tests, radiological diagnostics are essential for enabling a specific treatment. From a surgical point of view the radiologist is expected to help in differentiating between cases with indications for emergency surgery and cases eligible for elective surgery or conservative treatment. (orig.) [German] Der Begriff ''akutes Abdomen'' stellt keine eigenstaendige Erkrankung dar, sondern beschreibt einen kritischen klinischen Zustand, unter dessen Oberbegriff sich die unterschiedlichsten Krankheitsbilder subsumieren lassen. Das Zeitintervall zwischen dem Auftreten der ersten Symptome bis zur Einleitung einer gezielten Therapie ist fuer die Prognose der Patienten der entscheidende Faktor. Aus diesem Grund bestehen besondere Anforderungen an die bildgebende Diagnostik, die dazu beitragen soll, innerhalb kuerzester Zeit eine moeglichst genaue Diagnose zu stellen. Neben Anamnese, klinischer Untersuchung und Labordiagnostik stellt die radiologische Untersuchung einen wesentlichen Baustein vor der Therapieeinleitung dar. Aus chirurgischer Sicht muessen Krankheitsbilder, die eine sofortige Notfalloperation erforderlich machen, von Erkrankungen differenziert werden, die eine elektive Chirurgie oder ein konservatives Vorgehen indizieren.

In the early 1960s, Joachim Brugsch, one of the founders of Clinical Chemistry and Laboratory Medicine (CCLM) (then Zeitschrift für Klinische Chemie), had the idea to found a journal in the upcoming field of clinical chemistry. He approached Ernst Schütte, who was associated with the De Gruyter publishing house through another journal, to participate, and Schütte thus became the second founder of this Journal. The aim was to create a vehicle allowing the experts to express their opinions and raise their voices more clearly than they could in a journal that publishes only original experimental papers, a laborious and difficult, but important endeavor, as the profession of clinical chemistry was still in the early stages of development at this time. The first issue of this Journal was published in early 1963, and today, we are proud to celebrate the 50th anniversary of CCLM. This review describes the development of this Journal in light of the political situation of the time when it was founded, the situation of the publisher Walter De Gruyter after the erection of the Berlin Wall, and the development of clinical chemistry, and later on, laboratory medicine as a well-acknowledged discipline and profession.

�� utilisation of voluntary skills-lab training in order to reach a sufficient concordance between students’ requirements and faculty offers, as well as resource management.[german] Zielsetzung: Die Vermittlung klinisch-praktischer Fertigkeiten ist von entscheidender Bedeutung für die Berufsfähigkeit angehender Ärzte. Prozedurale Fertigkeiten werden dabei häufig zu allererst in sogenannten Skills-Labs trainiert, die eine geschützte Lernumgebung gewährleisten. Die Implementierung und auch Pflege von Skills-Labs stellt allerdings eine nicht geringfügige finanzielle Herausforderung dar. Aus diesem Grund hat sich die vorliegende Arbeit zum Ziel gesetzt, die Besuchsfrequenzen und –muster im Rahmen freiwilliger Skills-Lab-Unterrichtseinheiten zu untersuchen, um folgende Frage zu beantworten: Kann der in der Literatur beschriebene, motivationspsychologische Effekt des “Assessment drives learning” festgestellt werden und spiegelt sich dieser in dem Besuchsverhalten von Studierenden in freiwilligen Skills-Lab-Unterrichtseinheiten wider? Ausgehend von den Studienergebnissen sollen Empfehlungen für die Curriculumsplanung und das Ressourcenmanagement abgeleitet werden.Methode:.

In the early clinical phase the comprehensive imaging of patients with multiple trauma using helical CT is already established. Aim of this study was to assess whether MSCT may improve the patient management and the diagnostic results.The procedure is designed as follows: after life-thretening treatment x-ray of chest and ultrasound are carried out in the emergency room. Then the patient is moved to CT. From 1998 to december 2000 241 patients were examined using a single slice helical CT (Somatom plus 4), in 2001 79 patients using a 4-slice helical CT (Somatom VZ, Siemens Med.Sol.). After CT selected radiograms of the extremities were taken.359 of 360 procedures were carried out successfully. Excluding 1 case (death during 1-sl. h CT) all relevant lesions of head, neck, and body were diagnosed. Although the patients had an injury severity score of {approx}30. The change from 1slice-helical CT to 4 slice-helical CT allowed us to reduce the stay in the CT room from 28 to 16 min. The total lethality decreased by {approx}4%.Advantages for the patient arose from the standardized examination protocol using multislice CT. If integrated in an interdisciplinary management concept, it is a good compromise between examination time, comprehensive diagnostic imaging, life-saving therapeutic procedures, and therapy planning.

Die frühzeitige Abklärung chronischer Vulvabeschwerden unter standardmäßiger Einbeziehung einer Vulvabiopsie erlaubte es, auch Frühformen des LS zu erfassen. Nach klinischer und stanzbioptischer Diagnose eines LS wird in Anlehnung an die "Guidelines for the Management of Lichen Sclerosus" [1] ein serologisches Screening auf Autoantikörper (TPO-AK, TG-AK, Parietalzell- und antinukleäre Antikörper durchgeführt. Bei 263 unserer 278 LS-Patientinnen wurde ein serologisches Screening auf Autoimmunerkrankungen durchgeführt. Insgesamt hatten 58/263 LS-Patientinnen pathologisch erhöhte Thyroidperoxidase-(TPO- und/oder Thyreoglobulin- (TG- Antikörpertiter (23 %, davon 50/263 (19 % auch eine sonographisch bestätigte Hashimoto-Thyreoiditis. Bei 50 % dieser Hashimoto-Patientinnen war bereits im Vorfeld eine Hypothyreose bekannt, bei den restlichen 25 Patientinnen handelte es sich allerdings um eine Erstdiagnose im Rahmen des Screenings für LS. Aufgrund der hohen Prävalenz von Hashimoto-Thyreoiditis in LS-Patientinnen empfehlen wir bei allen Frauen mit LS ein Screening auf TPO- und TG-Antikörper. Bei erhöhten Titern sollte eine Abklärung mittels Schilddrüsensonogramm sowie eine Bestimmung von basalem "thyroid-stimulating hormone" (TSH, freiem T3 und freiem T4 erfolgen. In der Schilddrüsensprechstunde sollten Frauen mit Hashimoto-Thyreoiditis gezielt nach chronischen bzw. rezidivierenden anogenitalen Beschwerden, insbesondere Pruritus, Brennen oder Dyspareunie befragt werden. Bei positiver Anamnese ist eine Zuweisung an einen auf Vulvaerkrankungen spezialisierten Facharzt für Gynäkologie sinnvoll.

17 patients with hemophilic arthropathy of the knee joint were studied with static and dynamic MRT before and after i.v. bolus injection of Gadolinium-DTPA (0,1 mmol/kg body weight). After contrast enhancement, synovial proliferations exhibited an increase of signal intensity (SI) of FFE and SE images of 47.7% and 37.4% respectively, whereas muscle and fatty tissue, tendons, bone marrow and joint effusion revealed only minor increase in SI. The gradient of signal intensity (ratio SI/time) of pannus was 39,6% min. Gd-DTPA enhanced MRI studies delineate and quantify the synovial proliferations in hemophilic arthropathy. Dynamic studies in hemophilic arthropathy do not provide qualitative assessment of the inflammatory process. (orig.)

Intracerebral hemorrhage is a common cause of acute neurological deterioration and a frequent indication for emergency neuroimaging. Stroke symptoms are caused in 10 to 15% by intracerebral hemorrhage. It is often not possible to differentiate intracerebral hemorrhage from cerebral ischemia by clinical examination. The therapeutic decision between thrombolysis or conservative therapy is comprised by the etiology. To exclude intracerebral hemorrhage as the cause of clinical symptoms, a CT is usually performed. Localisation and extension of the acute intracerebral hemorrhage are easy to detect. Subacute and chronic intracerebral hemorrhage are better delineated with magnetic resonance imaging. The different signal of the hemorrhage can be used for the age of the intracerebral hemorrhage. The cause of a non-traumatic intracerebral hemorrhage is in over 60% hypertony, less frequent alcoholism, malformation, or amyloid angiopathy. Uncommon causes of hemorrhage are head trauma, blood dyscrasia, tumor or venous thrombosis. Non-traumatic intracerebral hemorrhage are most common in patients between 50 and 70 years. In younger patients a malformation should be excluded with a cerebral angiography. Intracerebral hemorrhages are usually conservatively treated, in some cases an operative decompression is performed.

In 21 horses with the anamnesis backproblems there had been a clinical, scan- and X-ray-examination of the thoracal and lumbar vertebra in special consideration of the spinosus process and the dorsal intervertebral joint. But there was not always a relation between the clinical signs and X-rays or scan results. Not all positive X-rays found their corresponding scan activity and not all scan activities took place in X-rays. In many cases there was pathological change of the spinosus process and arthropathy of the dorsal intervertebral joint at the same time. Only with X-raying it is not possible to decide to operate the thoracolumbal, interspinale syndrom (TIS) or not [German] Bei 2l Pferden mit dem Vorbericht 'Rückenleiden' wurden klinisch, röntgenologisch und szintigraphisch die Brust- und Lendenwirbelsäule unter besonderer Berücksichtigung der Dornfortsätze und der dorsalen Intervertebralgelenke untersucht. Die erhobenen klinischen, röntgenologischen und szintigraphischen Befunde stimmten nicht immer überein. So waren nicht alle erhobenen Röntgenbefunde szintigraphisch aktiv, und für die szintigraphisch aktiven Zonen konnten nicht immer rötgenologische Befunde erhoben werden. Bei den Veränderungen der Dornfortsätze lagen oft gleichzeitig Arthrosen der dorsalen Intervertebralgelenke vor. Die Indikation ftir die Operation des thorakolumbalen, interspinalen Syndroms (TIS) kann deshalb nicht mit der Röntgenuntersuchung der Dornfortsätze allein gestellt werden.

Das deutsche Neurodermitis-Register TREATgermany wurde als weltweit erstes Register für Patienten mit schwerer Neurodermitis 2011 initiiert. Erwachsene mit schwerer Neurodermitis (aktuelle/frühere antientzündliche Systemtherapie und/oder objektiver SCORAD ≥ 40) werden über einen Zeitraum von 24 Monaten prospektiv beobachtet. Anhand validierter Erhebungsinstrumente werden die klinische Erkrankungsschwere (EASI, SCORAD), Lebensqualität (DLQI), Symptome, globale Erkrankungsschwere sowie die Patientenzufriedenheit erfasst und die durchgeführten Therapien dokumentiert. Die vorliegende Analyse beschreibt die Charakteristika, Therapiewahl und Wirksamkeit der eingesetzten antiinflammatorischen Systemtherapien der bis Oktober 2014 eingeschlossenen Patienten. An fünf Zentren wurden insgesamt 78 Patienten (Durchschnittsalter 39 Jahre, 61 % männlich) eingeschlossen. Bei den Patienten besteht eine hohe Inanspruchnahme ambulanter und stationärer Leistungen. Ciclosporin war das am häufigsten eingesetzte Systemtherapeutikum und zeigte die höchste klinische Effektivität (EASI-50-Ansprechrate 51 %; EASI-75-Ansprechrate 34 % nach zwölfwöchiger Therapie). Azathioprin, Methotrexat (MTX), Prednisolon oral, Mycophenolat, Alitretinoin und Leflunomid wurden ebenfalls bei einzelnen Patienten eingesetzt. Die vorliegende Registerauswertung gibt wichtige Hinweise zur derzeitigen Versorgung von Erwachsenen mit schwerer Neurodermitis in Deutschland, dokumentiert die hohe Erkrankungslast, den Nutzen vorhandener Therapien und den Bedarf an weiteren, effektiven und in der Langzeitanwendung sicheren Therapieoptionen. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Functional magnetic resonance imaging (fMRI) is the most common noninvasive technique in functional neuroanatomy. The capabilities and limitations of the method will be discussed based on a short review of the current knowledge about the neurovascular relationship. The focus of this article is on current methodical and technical problems regarding fMRI-based detection and localization of neuronal activity. Main error sources and their influence on the reliability and validity of fMRI-methods are presented. Appropriate solution strategies will be proposed and evaluated.

The value of MR imaging for the detection of hyaline cartilage lesions using 2-D spin-echo and 3-D gradient-echo imaging was evaluated in an animal experiment in 10 dogs and in a clinical study in 30 patients. MR imaging findings were compared with histopathological and arthroscopy findings, respectively. Using MRI neither grade I nor grade II hyaline cartilage lesions were detectable. In the animal experiments 77% of grade III lesions and all the grade IV lesions were seen. However, in the clinical study only about the half of grade III and IV lesions were detected. 3-D gradient-echo MR imaging was superior to 2-D spin-echo imaging (p<0.001), while 3-D FLASH and 3-D FISP did not differ significantly in the detection rate (p<0.34). 3-D gradient-echo MR imaging seems to be the best method for the delineation of high grade cartilage lesions. However, early stages of cartilage degeneration are invisible even with this imaging modality. (orig.) [Deutsch] Die Wertigkeit der MRT in der Erfassung von Knorpellaesionen mit 2-D-Spin-Echo- und 3-D-Grafienten-Echo-Sequenzen wurde in einer tierexperimentellen Untersuchung an 10 Hunden sowie in einer klinischen Studie an 30 Patienten ueberprueft. Die kernspintomographischen Ergebnisse wurden mit dem pathologisch-anatomischen Befund bzw. der Arthroskopie verglichen. MR-tomographisch konnten weder Grad-I- noch Grad-II-Knorpellaesionen erfasst werden. Die Erkennbarkeitsrate der Grad-III- und -IV-Laesionen lag fuer die tierexperimentellen Untersuchungen bei 77 bzw. 100%, waehrend klinisch nur etwa 50% dieser Veraenderungen erkannt werden konnten. Dabei waren die 3-D-Gradienten-Echo-Sequenzen den 2-D-Spin-Echo-Sequenzen signifikant ueberlegen (p<0,001), waehrend sich die 3-D-Gradienten-Echo-Sequenzen FISP und FLASH nicht voneinander unterschieden (p<0,34). Derzeit muessen die 3-D-Gradienten-Echo-Sequenzen als die beste Methode zur Erfassung hoehergradiger Knorpellaesionen angesehen werden. Fruehe Stadien der Knorpelschaedigung sind

Acute chest pain represents a very common clinical occurrence and at the same time poses a severe diagnostic dilemma. It can be due to an acute life-threatening event such as acute cardiac infarct, or a relatively harmless condition of pain and illness (e.g. vertebrogenic pain) under the main symptom category of acute chest pain. This often unclear symptomatic, behind which there can always be a life-threatening disease leads to an exaggerated grouping of patients into emergency cases and to an increased number of inpatients for observation. The diagnosis of acute coronary syndrome with no initial ECG changes typical for ischemia is especially problematic. The availability of modern multidetector computed tomography is becoming increasingly more important for radiologists in the diagnosis and clarification of acute chest pain. In this article the clinical difficulties and radiology options for the diagnosis of patients with acute chest pain will be presented and possible future algorithms for diagnosis will be discussed. (orig.) [German] Der akute Thoraxschmerz repraesentiert ein sehr haeufiges klinisches Beschwerdebild und gleichzeitig ein grosses diagnostisches Dilemma, koennen sich doch sowohl lebensbedrohliche akute Ereignisse (wie der akute Herzinfarkt) als auch mehr oder weniger harmlose Schmerzzustaende und Erkrankungen (wie vertebrogene Schmerzen) unter dem Leitsymptom 'akuter Thoraxschmerz' praesentieren. Diese oft nicht eindeutige Symptomatik, hinter der immer auch ein lebensbedrohliches Krankheitsbild stecken kann, fuehrt zu einer Uebertriagierung der Patienten in Notaufnahmen und zu einer grossen Anzahl an stationaeren 'Absicherungsaufnahmen'. Besonders die Diagnose eines akuten Koronarsyndroms (AKS) bei initial fehlenden ischaemietypischen EKG-Veraenderungen stellt eine spezielle Problematik dar. Durch die Verfuegbarkeit moderner ultraschneller Multidetektorcomputertomographen (MDCT) spielt der Radiologe in der Diagnostik und

Positron emission tomography with FDG (FDG-PET) is a new technique, which displays the cellular metabolic activity. Since tumors exhibit an increased metabolic activity when compared to normal tissue, this imaging modality has a particularly high importance. FDG-PET is not only useful for localizing and staging of malignant tumors, but also to evaluate therapy response. In this context, PET is superior to morphologically orientated modalities, because therapeutically induced changes in glucose metabolism precede morphologic alterations. Numerous studies indicate, that PET will play an important role in radiooncology concerning therapy planning and monitoring the effects of therapy during and after treatment. Further clinical studies are necessary to evaluate the information provided by FDG-PET more precisely. Coincidence gamma cameras with adequate imaging characteristics will gain enhanced importance to meet these increasing demands. (orig.) [German] Die Positronenemissionstomographie mit FDG (FDG-PET) ist ein neues Verfahren, das die Stoffwechselaktivitaet von Zellen bildlich wiedergibt. Da Tumorgewebe im Vergleich zu normalem Gewebe einen erhoehten Stoffwechsel aufweist, hat dieses Untersuchungsverfahren in der Onkologie einen besonders hohen Stellenwert. Neben der Lokalisations- und Ausbreitungsdiagnostik eignet sich die FDG-PET zur Erfolgsbeurteilung. Die PET ist hierin den anderen morphologischen Verfahren ueberlegen, da die Veraenderungen des Glukosemetabolismus durch therapeutische Massnahmen morphologischen Veraenderungen vorausgehen. Zahlreiche Untersuchungen lassen erkennen, dass die PET fuer die Radioonkologie einen wichtigen Stellenwert einnehmen wird. Dies betrifft die Bestrahlungsplanung und das Therapiemonitoring waehrend und nach einer Behandlung. Weitere klinische Studien sind notwendig, um die Aussagekraft der FDG-PET besser zu evaluieren. Den Koinzidenz-Gammakameras mit adaequaten Bildgebungseigenschaften kommt eine zunehmende Bedeutung zu, um

Allerdings ist die Vorhersagbarkeit des Prostatakarzinomes hinsichtlich seines klinischen Verlaufes schwierig. Methodik und Technik: Das histologische Ergebnis nach radikaler Prostatektomie bei Patienten mit nur einer einzigen positiven Stanzbiopsie wurde von uns nachuntersucht. Die Biopsie erfolgte als Oktantenbiopsie nach den derzeit gültigen Schemata, radikal prostatektomiert wurde in auschließlich retropubischer aszendierender Form. Ergebnisse: Die Untersuchung der histologischen Ergebnisse zeigte in einem überraschend hohen Prozentsatz (58 % einen Karzinombefund in beiden Prostataseitenlappen (pT2c, in 12 % eine Organüberschreitung. Es fand sich in lediglich 18 % der Fälle ein kleines Karzinom in einem Seitenlappen (pT2a. Schlußfolgerung: Bei auch nur einer positiven Stanzbiopsie kann keine Vorhersage für das histologische Stadium nach Radikaloperation und damit den wahrscheinlichen klinischen Verlauf getroffen werden.

Zusammenfassung Hintergrund Persistierende Infektionen mit humanen Papillomviren sind die notwendige Ursache des Zervixkarzinoms. Die Entwicklung von HPV-basierten Präventionsverfahren, der HPV Impfung und der HPV-Testung, führt derzeit zu umfangreichen Veränderungen von Zervixkarzinom-Vorsorgeprogrammen. Eine Dekade nach Einführung der HPV-Imfpung in vielen Ländern werden bereits Reduktionen von HPV-Infektionen und Krebsvorstufen in jungen Frauen beobachtet. Der Fokus liegt jetzt auf der Integration von neuen Testverfahren im Screening von Populationen mit zunehmenden Impfraten. Ergebnisse und Schlussfolgerung Ein erfolgreiches Zervixkarzinom-Vorsorgeprogramm besteht aus verschiedenen Komponenten, vom primären Screening über die Triage zur Kolposkopie mit Biopsie, um Frauen mit Kresbvorstufen zu identifizieren, die eine therapeutische Intervention benötigen. Im primären Screening wird eine kleine Gruppe von Frauen mit erhöhtem Risiko für eine Krebsvorstufe identifiziert, während die grosse Mehrheit kein erhöhtes Risiko hat. Je nach primärem Testverfahren werden in screen-positiven Frauen zusätzliche Triage-Tests durchgeführt, um zu entscheiden, wer zur Kolposkopie überwiesen werden sollte. Derzeit gibt es drei verschiedene Ansätze für das primäre Zervixkarzinomscreening: Die Zervix-Zytologie, die HPV-Testung, und die HPV-Zytologie Ko-Testung. Zahlreiche Triage-Tests für HPV-positive Frauen werden derzeit untersucht, darunter sind die Zytologie, HPV-Genotypisierung, p16/Ki-67 Zytologie, und diverse Methylierungstests. Die steigende Anzahl an Optionen für die Früherkennung des Zervixkarzinoms stellt eine Herausforderung für klinische Leitlinien dar. Die zunehmende Komplexität von Vorsorgeprogrammen kann zur Verunsicherung von Ärzten und von am Screening teilnehmenden Frauen führen. Die Präzisions-Prävention des Zervixkarzinoms ist eine neuer Ansatz, der umfangreiche Risikodaten basierend auf der individuellen Vorgeschichte und von

Besides applications for power generation and as a transport fuel, biomass can also be used as a chemical feedstock. If the chemical industry in Europe were to switch to 25% biofeedstocks, the sector's demand for biomass would approximate or even slightly exceed that of the transport sector. There are a number of options for biomass use in the chemical industry, with varying requirements for specific types of biomass. To a large extent, the raw biomass used by the chemical industry would be roughly equivalent to that currently used for transport biofuels, although certain routes would involve different bio resources. Compared with applications for transport fuels, use of biomass as a chemical feedstock often has greater environmental benefits, at lower cost. It would be very useful to establish sustainability criteria for the use of biomass by the chemical industry, too. Based partly on this study by CE Delft, the Commission for Sustainability Aspects of Biomass (the Corbey Commission) has drawn up an advisory document recommending introduction of sustainability criteria for use of biomass by the chemical industry [Dutch] Biomassa kan gebruikt wordt als bron voor elektriciteit en transportbrandstof maar ook als grondstof voor de chemie. Als de chemie in Europa voor 25% over zou schakelen op biomassa als grondstof dan zou de vraag vanuit deze sector naar vergelijkbaar of nog iets groter worden dan de vraag naar biomassa van de transportsector. Er zijn verschillende manieren om biomassa in te zetten in de chemie. Deze keuzes leiden tot een verschillende vraag naar soorten biomassa. Een groot deel van de grondstoffen voor biochemie komt overeen met grondstoffen voor de biotransportsector. Sommige routes vragen om andere grondstoffen. Vergeleken met biomassa in transport geeft inzet van biomassa in chemie vaak een hoger milieuvoordeel tegen lagere kosten. Het zou heel nuttig zijn om ook voor biomassa die gebruikt wordt door de chemie duurzaamheidscriteria op te

Future dynamics in f(R) theories

International Nuclear Information System (INIS)

Mueller, D.; Andrade, V.C. de; Maia, C.; Reboucas, M.J.; Teixeira, A.F.F.

2015-01-01

The f(R) gravity theories provide an alternative way to explain the current cosmic acceleration without invoking a dark energy matter component used in the cosmological modeling in the framework of general relativity. However, the freedom in the choice of the functional forms of f(R) gives rise to the problem of the degeneracy among these gravity theories on theoretical and (or) observational grounds. In this paper we examine the question as to whether the future dynamics can be used to break the degeneracy between f(R) gravity theories by investigating the dynamics of spatially homogeneous and isotropic dust flat models in two f(R) gravity theories, namely the well known f(R) = R+αR n gravity and another byAviles et al., whose motivation comes from the cosmographic approach to f(R) gravity. We perform a detailed numerical study of the dynamics of these theories taking into account the recent constraints on the cosmological parameters made by the Planck Collaboration. We demonstrate that besides being useful for discriminating between these two f(R) gravity theories, the future dynamics technique can also be used to determine the finite-time behavior as well as the fate of the Universe in the framework of these f(R) gravity theories. There also emerges from our analysis the result that one still can have a dust flat FLRWsolution with a big rip, if gravity is governed by f(R) = R+αR n . We also show that FLRW dust solutions with f'' < 0 do not necessarily lead to singularities. (orig.)

To detect regional differences in accompanying metabolic changes, {sup 1}H-Magnetic Resonance Spectroscopic Imaging was performed in 16 patients with Alzheimer`s disease (AD); the clinical diagnosis was based upon DSM-III-R and NINCDS-ADRDA guidelines. In the hippocampal region metabolic maps of the local distribution of N-acetylaspartate (NAA), choline (Cho), creatine compounds (P(Cr)) and lactate were determined. Ratios of Cho/NAA, (P)Cr/NAA and Cho/(P)Cr calculated from selected hippocampal spectra were compared to those from healthy volunteers (n=17). AD patients demonstrated an increase of Cho/NAA and (P)Cr/NAA ratios caused by increased choline compounds and decreased NAA. These alterations were observed in 11/12 cases in the hippocampal and in 7/12 in the temporo-occipital region. Hippocampal Cho/NAA ratios (0.56{+-}0.19) were significantly elevated compared with controls. The observed elevation of choline compounds in the hippocampus supports the hypothesis that alterations in the cholinergic system play an important role in Alzheimer`s disease. The observed reduction of NAA is due to neuronal degeneration.

In Hoehe des Hippocampus wurden transaxiale ``Metabolitenkarten`` der regionalen Verteilung von N-Acetyl-Aspartat (NAA), cholinhaltiger Verbindungen (Cho), Gesamtkreatin (P(Cr)) und Laktat erstellt. Zur Quantifizierung der Unterschiede zum Normalkollektiv (n=17) wurden die Metabolitenquotienten Cho/NAA, (P)Cr/NAA und Cho/(P)Cr, insbesondere aus der Hippocampusregion, ermittelt. Das Krankheitsbild des M. Alzheimer stellte sich durch eine Erhoehung der Quotienten Cho/NAA und Cho/(P)Cr dar, wobei neben einer Cholinerhoehung die Reduktion des Neurotransmitters NAA

f(R) gravity solutions for evolving wormholes

Energy Technology Data Exchange (ETDEWEB)

Bhattacharya, Subhra [Presidency University, Department of Mathematics, Kolkata (India); Chakraborty, Subenoy [Jadavpur University, Department of Mathematics, Kolkata (India)

2017-08-15

The scalar-tensor f(R) theory of gravity is considered in the framework of a simple inhomogeneous space-time model. In this research we use the reconstruction technique to look for possible evolving wormhole solutions within viable f(R) gravity formalism. These f(R) models are then constrained so that they are consistent with existing experimental data. Energy conditions related to the matter threading the wormhole are analyzed graphically and are in general found to obey the null energy conditions (NEC) in regions around the throat, while in the limit f(R) = R, NEC can be violated at large in regions around the throat.

The modified theories of gravity, especially the f(R) gravity, have attracted much attention in the last decade. This paper is devoted to exploring plane-symmetric solutions in the context of metric f(R) gravity. We extend the work on static plane-symmetric vacuum solutions in f(R) gravity already available in the literature [1, 2]. The modified field equations are solved using the assumptions of both constant and nonconstant scalar curvature. Some well-known solutions are recovered with power-law and logarithmic forms of f(R) models.

Prostata-Screening: sinnvoll und teuer?

Full Text Available Im Jahr 2008 lautet die wesentlichste Aussage zur individuellen Vorsorge: "Nicht jedes früh erkannte Prostatakarzinom muss behandelt werden, aber das behandlungsbedürftige muss früh erkannt werden!" Das Prostatakarzinom kann nur dann einer kurativen Therapie zugeführt werden, wenn es in einem organbegrenzten Stadium entdeckt wird. Hier ist es jedoch asymptomatisch. Miktionsbeschwerden entstehen durch die benigne Prostatahyperplasie. Bevor eine "Kaskade" mit Messungen des prostataspezifischen Antigens und digital-rektaler Untersuchung ausgelöst wird, muss nicht nur über das Risiko Prostatakrebs, sondern auch über die evtl. Therapieschritte inkl. Nebenwirkungen informiert werden. Eine Altersgruppe von 50 bis 70 Jahren, bei familiärer Vorgeschichte ab 45 Jahren, ist anzusprechen. Bei Bejahung der Abklärung hat direkt ab einem PSA von 4,0 ng/ml oder auffälliger digitalrektaler Untersuchung eine weitere bioptische Abklärung zu erfolgen. Die früher beschriebene PSA- "Grauzone" 4–10 ng/ml mit abwartender Haltung existiert nicht, da sie vermehrt zu organüberschreitenden, nicht mehr kurativ behandelbaren Stadien geführt hat. Außerdem darf ein erhöhter Anteil des freien PSA oberhalb des Cut-offs 4,0 ng/ml nicht zu einer Aufschiebung der Biopsieindikation führen. Eine besondere Risikogruppe besteht bei PSA 3–4 ng/ml und reduziertem freien Anteil von ca. ≤ 12 %. Hier scheint eine Indikation zur Biopsie frühzeitiger gegeben. Zirka 2,3–25 % der initial entdeckten Karzinome können klinisch irrelevant sein und lassen sich durch Vorhersagemodelle mittels PSA-Dichte, Gleason-Score und Tumorbefall der Biopsien prätherapeutisch bestimmen. Sie können einer Active-Surveillance-Strategie (lediglich kontrollierte Beobachtung zugeführt werden. Diese Patienten werden kontrolliert beobachtet mit initial halbjährlichem PSA und jährlicher Prostatabiopsie.

Analyses of 13 samples of Martian surface materials with the Viking X-ray fluorescence spectrometers show SiO2 similar to that of terrestrial mafic rocks, whereas Fe2O3, Cl, and S are higher and Al2O3, K2O, Rb, Sr, Y, and Zr are lower. Low totals suggest presence of CO2, H2O, and Na2O. Duricrust fragments are higher in S than fines, but samples from both landing sites are surprisingly similar. We suggest that Martian surface materials are aeolian deposits of complex mixtures of weathering products of maficultramafic rocks, possibly consisting of iron-rich clays, sulfates, iron oxides, carbonates, and chlorides.

During a period of two years, 134 patients with pseudo-arthrosis of the scaphoid were examined by conventional radiography and by MRI in the course of a prospective study. The aim of the study was to define radiological staging using contrast enhanced MRI in order to improve the prognostic criteria. All MRI examinations were carried out with a 1.5 Tesla scanner (SP63) using a surface coil and T{sub 1} weighted spin echo sequences in sagittal and frontal projection and frontal FLASH T{sub 2}-sequences and axial spin echo T{sub 2} sequences. The T{sub 1} weighted SE sequences in frontal projection were carried out before and after iv contrast (0.1 mmol Gd-DTPA/kg KG). All sequences were compared with conventional radiographs and the operative findings. Eight patients in stage 0 showed high signal intensity of both fragments in T{sub 1} weighted SE sequences and at surgery there was good vascularisation. In 22 cases there was reduced signal intensity in at least one fragment (stage I). 45 patients with scaphoid pseudo-arthrosis showed complete signal loss but marked contrast uptake with still vital nuclei at surgery (stage II). In 22 patients, there was no increase in signal intensity after contrast and complete loss of vitality of the fragments at surgery. Staging was not possible in 37 patients because of previous operative intervention. The use of contrast enhanced MRI provides additional information compared with conventional radiography or plain MRI. (orig.)

We shall investigate the properties of a congruence of geodesics in the framework of Palatini f(R) theories. We shall evaluate the modified geodesic deviation equation and the Raychaudhuri's equation and show that f(R) Palatini theories do not necessarily lead to attractive forces.

Nonlinear evolution of f(R) cosmologies. I. Methodology

International Nuclear Information System (INIS)

Oyaizu, Hiroaki

2008-01-01

We introduce the method and the implementation of a cosmological simulation of a class of metric-variation f(R) models that accelerate the cosmological expansion without a cosmological constant and evade solar-system bounds of small-field deviations to general relativity. Such simulations are shown to reduce to solving a nonlinear Poisson equation for the scalar degree of freedom introduced by the f(R) modifications. We detail the method to efficiently solve the nonlinear Poisson equation by using a Newton-Gauss-Seidel relaxation scheme coupled with the multigrid method to accelerate the convergence. The simulations are shown to satisfy tests comparing the simulated outcome to analytical solutions for simple situations, and the dynamics of the simulations are tested with orbital and Zeldovich collapse tests. Finally, we present several static and dynamical simulations using realistic cosmological parameters to highlight the differences between standard physics and f(R) physics. In general, we find that the f(R) modifications result in stronger gravitational attraction that enhances the dark matter power spectrum by ∼20% for large but observationally allowed f(R) modifications. A more detailed study of the nonlinear f(R) effects on the power spectrum are presented in a companion paper.

THE LIFETIME AND POWERS OF FR IIs IN GALAXY CLUSTERS

International Nuclear Information System (INIS)

Antognini, Joe; Bird, Jonathan; Martini, Paul

2012-01-01

We have identified and studied a sample of 151 FR IIs found in brightest cluster galaxies (BCGs) in the MaxBCG cluster catalog with data from FIRST and NVSS. We have compared the radio luminosities and projected lengths of these FR IIs to the projected length distribution of a range of mock catalogs generated by an FR II model and estimate the FR II lifetime to be 1.9 × 10 8 yr. The uncertainty in the lifetime calculation is a factor of two, primarily due to uncertainties in the intracluster medium (ICM) density and the FR II axial ratio. We furthermore measure the jet power distribution of FR IIs in BCGs and find that it is well described by a log-normal distribution with a median power of 1.1 × 10 37 W and a coefficient of variation of 2.2. These jet powers are nearly linearly related to the observed luminosities, and this relation is steeper than many other estimates, although it is dependent on the jet model. We investigate correlations between FR II and cluster properties and find that galaxy luminosity is correlated with jet power. This implies that jet power is also correlated with black hole mass, as the stellar luminosity of a BCG should be a good proxy for its spheroid mass and therefore the black hole mass. Jet power, however, is not correlated with cluster richness, nor is FR II lifetime strongly correlated with any cluster properties. We calculate the enthalpy of the lobes to examine the impact of the FR IIs on the ICM and find that heating due to adiabatic expansion is too small to offset radiative cooling by a factor of at least six. In contrast, the jet power is approximately an order of magnitude larger than required to counteract cooling. We conclude that if feedback from FR IIs offsets cooling of the ICM, then heating must be primarily due to another mechanism associated with FR II expansion.

Experimental and theoretical investigations of the decays of 206Fr and 208Fr

International Nuclear Information System (INIS)

Ritchie, B.G.

1979-01-01

206 Fr and 208 Fr were mass separated and observed with large-volume semiconductor detectors in calibrated geometries. Alpha, gamma, and electron singles and gamma-gamma and gamma-electron coincidence data were taken. The alpha decay experiments permitted the determination of the alpha branching ratios for 206 208 Fr as well as 205 207 Fr. The method used includes the information obtained from the electron capture decay studies of those nuclei. The alpha branching ratios obtained are generally higher than those reported previously. Energies and half-lives are in general agreement with previous measurements. The alpha measurements also revealed the presence of a heretofore unobserved alpha-emitting isomer in 206 Fr. The isomer has a half-life of 0.7 +- 0.1 seconds, and the energy of the associated alpha decay is 6.930 +- 0.005 MeV. Gamma data taken with the alpha measurements suggest that the isomeric level is 531 keV above the 206 Fr ground state, with the associated alpha decay populating a level at 391 keV in the 202 At nucleus. Measured alpha branching ratios were analyzed with the Rasmussen reduced width formalism. All observed francium decays were deduced to be unhindered. This study produced detailed level schemes for 206 Rn and 208 Rn. The gamma and electron data permitted the determination of internal conversion coefficients, multipolarities, spins, and parities. It appears from systematics that two different bands of states above J/sup π/ = 4+ are populated by in-beam studies. The deduced level scheme of 208 Rn was studied in the interacting boson approximation (IBA) with the computer code PHINT. The level scheme is readily explained with this model up to around 2 MeV. Good agreement between theory and experiment was also obtained for 204 Rn and 206 Rn, but the limited detail in these decay schemes does not provide conclusive evidence for the applicability of the IBA. 28 figures, 10 tables

Dynamics of anisotropic power-law f(R) cosmology

2016-01-01

Modified theories of gravity have attracted much attention of the researchers in the recent years. In particular, the f(R) theory has been investigated extensively due to important f(R) gravity models in cosmological contexts. This paper is devoted to exploring an anisotropic universe in metric f(R) gravity. A locally rotationally symmetric Bianchi type I cosmological model is considered for this purpose. Exact solutions of modified field equations are obtained for a well-known f(R) gravity model. The energy conditions are also discussed for the model under consideration. The viability of the model is investigated via graphical analysis using the present-day values of cosmological parameters. The model satisfies null energy, weak energy, and dominant energy conditions for a particular range of the anisotropy parameter while the strong energy condition is violated, which shows that the anisotropic universe in f(R) gravity supports the crucial issue of accelerated expansion of the universe.

Clustering of galaxies with f(R) gravity

2018-02-01

Based on thermodynamics, we discuss the galactic clustering of expanding Universe by assuming the gravitational interaction through the modified Newton's potential given by f(R) gravity. We compute the corrected N-particle partition function analytically. The corrected partition function leads to more exact equations of state of the system. By assuming that the system follows quasi-equilibrium, we derive the exact distribution function that exhibits the f(R) correction. Moreover, we evaluate the critical temperature and discuss the stability of the system. We observe the effects of correction of f(R) gravity on the power-law behaviour of particle-particle correlation function also. In order to check the feasibility of an f(R) gravity approach to the clustering of galaxies, we compare our results with an observational galaxy cluster catalogue.

Symmetric Atom–Atom and Ion–Atom Processes in Stellar Atmospheres

Directory of Open Access Journals (Sweden)

Vladimir A. Srećković

2017-12-01

Full Text Available We present the results of the influence of two groups of collisional processes (atom–atom and ion–atom on the optical and kinetic properties of weakly ionized stellar atmospheres layers. The first type includes radiative processes of the photodissociation/association and radiative charge exchange, the second one the chemi-ionisation/recombination processes with participation of only hydrogen and helium atoms and ions. The quantitative estimation of the rate coefficients of the mentioned processes were made. The effect of the radiative processes is estimated by comparing their intensities with those of the known concurrent processes in application to the solar photosphere and to the photospheres of DB white dwarfs. The investigated chemi-ionisation/recombination processes are considered from the viewpoint of their influence on the populations of the excited states of the hydrogen atom (the Sun and an M-type red dwarf and helium atom (DB white dwarfs. The effect of these processes on the populations of the excited states of the hydrogen atom has been studied using the general stellar atmosphere code, which generates the model. The presented results demonstrate the undoubted influence of the considered radiative and chemi- ionisation/recombination processes on the optical properties and on the kinetics of the weakly ionized layers in stellar atmospheres.

Bei der (18) F-Fluordeoxyglucose-Positronenemissionstomographie/Computertomographie (FDG-PET/CT) ergeben sich häufig Zufallsbefunde. In der vorliegenden Studie konzentrierten wir uns auf mittels FDG-PET/CT erhaltene Zufallsbefunde bei Patienten mit kutanem Melanom und überprüften deren Relevanz hinsichtlich weiterer diagnostischer Maßnahmen und Interventionen. Die Krankenakten von 181 konsekutiven Melanom-Patienten wurden retrospektiv ausgewertet, um das Management von Zufallsbefunden zu dokumentieren. Der Schwerpunkt lag dabei auf den histologischen Befunden. Bei 33 von 181 (18 %) Patienten lagen 39 relevante Zufallsbefunde vor, und zwar im Kolorektalbereich (n = 15 Patienten), in der Schilddrüse (n = 8), der Prostata (n = 2), dem Bewegungsapparat (n = 2), in Lymphknoten (n = 2), der Parotis (n = 1), den Mandeln (n = 1), den Nieren (n = 1) und der Gallenblase (n = 1). Bei 25 Patienten schlossen sich weitere diagnostische Verfahren an, wobei in 21 Fällen ein klinisches Korrelat nachgewiesen wurde. Bei 16 von 21 Patienten ergab sich eine Neoplasie, darunter fünf maligne Läsionen (vier Kolonkarzinome und ein Prostatakarzinom). Die Malignome wurden frühzeitig diagnostiziert und in der Mehrzahl der Fälle erfolgreich entfernt. Der Einsatz der FDG-PET/CT als Routine-Diagnostik wird in den Leitlinien empfohlen und ist indiziert bei malignem Melanom ab Stadium IIC. In dieser Studie wurden auf effektive Weise ansonsten nicht erkannte Krebserkrankungen, insbesondere Kolonkarzinome, detektiert. In den meisten Fällen war eine frühe Intervention möglich. Zufallsbefunde durch FDG-PET/CT sollten, unter Berücksichtigung des Zustands und der Wünsche des Patienten, mit den geeigneten diagnostischen Maßnahmen abgeklärt werden. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

The level structures of 211 Fr, 212 Fr and 213 Fr have been observed to high spins, approx. 28(h/2π) (and excitation energies approx. 8 MeV) using a variety of gamma-ray spectroscopic techniques. The structure of these nuclides is discussed in terms of couplings of single particle states through empirical shell model calculations. Good agreement with experiment is obtained. In 212 Fr and 213 Fr core-excited configurations are required to explain the properties of the highest states. A number of long lived states were observed in each nucleus some of which decay by by enhanced E3 transitions. The E3 transition strengths are discussed

In-depth investigation of (α-γ)-coincidences at the 225 Ac decay is carried out. Twenty-one new weak γ-rays are found; 18 γ-rays earlier ascribed to the 225 Ac decay are not confirmed. The quantitative analysis of the (α-γ)-coincidences makes it possible to find the intensity of population of 221 Fr levels by the α decay and multipolarities of five weak γ-transitions. The conversion electron spectrum is investigated in the range of 5-24 keV with a high (some 20 eV) energy resolution. A new M1 type 10.6-keV γ-transition is found. The proposed 225 Ac decay scheme includes 31 excited 221 Fr states. Parities are established for 16 of them. Possible spin values are proposed for 221 Fr levels. Properties of excited 221 Fr states are satisfactorily described by the quasiparticle-phonon nuclear model without the assumption of static octupole deformation

High-grade use of waste propane streams in the Dutch chemical industry. An exploratory study in the context of the Chemical Industry Roadmap; Hoogwaardig gebruik van reststromen propaan in de Nederlandse chemische industrie. Een verkenning binnen de Routekaart Chemie

In the context of the Dutch chemical industry's Roadmap the industry is actively seeking concrete ways of improving the efficiency of its products and processes. One option is to make higher-grade use of current waste streams, as feedstocks for other products, for example. This study focuses on propane waste streams from the oil and gas processing industry. Today these are used partly as fuel (fuel gas) but there are no technical barriers to converting propane to propylene, which can then be used as a feedstock. Higher-grade use of this particular waste stream leads to CO2 emission reductions in the production chain. Given the high market price of propylene, such a move may also be economically attractive. The study focuses on the Rotterdam region, because propane suppliers and companies seeking propylene are in closest proximity there [Dutch] In het kader van de Routekaart Chemie is de chemische industrie actief op zoek naar concrete opties om in haar processen en producten de efficiency te verhogen. Een route is daarbij om reststromen hoogwaardiger te benutten en in te zetten als grondstof voor andere producten. Dit onderzoek richt zich op reststromen propaan uit de olie- en gasverwerkende industrie. Deze worden nu deels als brandstof (stookgas) ingezet maar technisch is het mogelijk propaan om te zetten in propeen, dat als grondstof voor de chemische industrie kan worden gebruikt. Door het hoogwaardiger benutten van deze reststroom wordt in de keten een reductie van CO2 gerealiseerd. Tegelijk kan het economisch interessant zijn, vanwege de hoge marktprijzen van propeen. De studie focust op de regio Rotterdam, omdat leveranciers van propaan en afnemers van propeen daar het meest dichtbij elkaar gevestigd zijn.

Solar System constraints to general f(R) gravity

International Nuclear Information System (INIS)

Chiba, Takeshi; Smith, Tristan L.; Erickcek, Adrienne L.

2007-01-01

It has been proposed that cosmic acceleration or inflation can be driven by replacing the Einstein-Hilbert action of general relativity with a function f(R) of the Ricci scalar R. Such f(R) gravity theories have been shown to be equivalent to scalar-tensor theories of gravity that are incompatible with Solar System tests of general relativity, as long as the scalar field propagates over Solar System scales. Specifically, the parameterized post-Newtonian (PPN) parameter in the equivalent scalar-tensor theory is γ=1/2, which is far outside the range allowed by observations. In response to a flurry of papers that questioned the equivalence of f(R) theory to scalar-tensor theories, it was recently shown explicitly, without resorting to the scalar-tensor equivalence, that the vacuum field equations for 1/R gravity around a spherically symmetric mass also yield γ=1/2. Here we generalize this analysis to f(R) gravity and enumerate the conditions that, when satisfied by the function f(R), lead to the prediction that γ=1/2

f(R) gravity and chameleon theories

Brax, Philippe; Bruck, Carsten van de; Davis, Anne-Christine; Shaw, Douglas J.

2008-01-01

We analyze f(R) modifications of Einstein's gravity as dark energy models in the light of their connection with chameleon theories. Formulated as scalar-tensor theories, the f(R) theories imply the existence of a strong coupling of the scalar field to matter. This would violate all experimental gravitational tests on deviations from Newton's law. Fortunately, the existence of a matter dependent mass and a thin-shell effect allows one to alleviate these constraints. The thin-shell condition also implies strong restrictions on the cosmological dynamics of the f(R) theories. As a consequence, we find that the equation of state of dark energy is constrained to be extremely close to -1 in the recent past. We also examine the potential effects of f(R) theories in the context of the Eoet-wash experiments. We show that the requirement of a thin shell for the test bodies is not enough to guarantee a null result on deviations from Newton's law. As long as dark energy accounts for a sizeable fraction of the total energy density of the Universe, the constraints that we deduce also forbid any measurable deviation of the dark energy equation of state from -1. All in all, we find that both cosmological and laboratory tests imply that f(R) models are almost coincident with a ΛCDM model at the background level.

Alpha decay 225 Ac → 221Fr

Full text: Considerable attention has been given to nuclei with A = 220 - 230 recently. In this region there occurs transition from the spherical to the deformed nuclear shape, which gives rise to some specific features in the nuclear structure. In particular, negative parity levels with low excitation energies have been found in even-even nuclei from this region [1, 2]. One of the nuclei allowing experimental investigation of the above properties is 221 Fr. The nuclide 221 Fr is from the region of isotopes which does not include stable nuclei and thus it cannot be studied in several-nucleon transfer reactions. In addition, the neutron excess in this nucleus makes it impossible to study the nucleus in reactions with heavy ions. Experimental information on the 221 Fr level structure can only be gained from investigation of the 225 Ac (T 1/2 = 10 days) alpha decay or the 221 Rn (T 1/2 = 25 min) beta decay. In the latter case the possibilities of the investigation are restricted by difficulties in making of 221 Rn sources. Therefore, most information on the structure and properties of 221 Fr is derived from investigation of the 225 Ac α -decay [3]. In-depth investigation of ( α - γ )- coincidences at the 225 Ac decay is carried out. Twenty-one new weak γ - rays are found; 18 γ-rays earlier ascribed to the 225 Ac decay are not confirmed. The quantitative analysis of the ( α - γ )- coincidences makes it possible to find the intensity of 221 Fr levels by the decay and multipolarities of five weak γ -transitions. The conversion electron spectrum is investigated in the range of 5 † 24 keV with a high (some 20 eV) energy resolution. A new M1 type 10.6-keV γ-transition is found. The proposed 225 Ac decay scheme includes 31 excited 221 Fr states. Parities are established for 16 of them. Possible spin values are proposed for 221 Fr levels. Properties of excited 221 Fr states are satisfactorily described by the quasiparticle-phonon nuclear model without the

Constraint propagation equations of the 3+1 decomposition of f(R) gravity

International Nuclear Information System (INIS)

Paschalidis, Vasileios; Shapiro, Stuart L; Halataei, Seyyed M H; Sawicki, Ignacy

2011-01-01

Theories of gravity other than general relativity (GR) can explain the observed cosmic acceleration without a cosmological constant. One such class of theories of gravity is f(R). Metric f(R) theories have been proven to be equivalent to Brans-Dicke (BD) scalar-tensor gravity without a kinetic term (ω = 0). Using this equivalence and a 3+1 decomposition of the theory, it has been shown that metric f(R) gravity admits a well-posed initial value problem. However, it has not been proven that the 3+1 evolution equations of metric f(R) gravity preserve the (Hamiltonian and momentum) constraints. In this paper, we show that this is indeed the case. In addition, we show that the mathematical form of the constraint propagation equations in BD-equilavent f(R) gravity and in f(R) gravity in both the Jordan and Einstein frames is exactly the same as in the standard ADM 3+1 decomposition of GR. Finally, we point out that current numerical relativity codes can incorporate the 3+1 evolution equations of metric f(R) gravity by modifying the stress-energy tensor and adding an additional scalar field evolution equation. We hope that this work will serve as a starting point for relativists to develop fully dynamical codes for valid f(R) models.

Purpose: To present an advanced concept for patient-based navigation and to report on our first clinical experience with interventions in the cranium, of soft-tissue structures (breast, liver) and in the musculoskeletal system. Materials and Methods: A PC-based navigation system was integrated into an existing interventional MRI environment. Intraoperatively acquired 3D data were used for interventional planning. The information content of these reference data was increased by integration of additional image modalities (e. g., fMRI, CT) and by color display of areas with early contrast media enhancement. Within 18 months, the system was used in 123 patients undergoing interventions in different anatomic regions (brain: 64, paranasal sinus: 9, breast: 20, liver: 17, bone: 9, muscle: 4). The mean duration of 64 brain interventions was compared that of 36 procedures using the scanner's standard navigation. Results: In contrast with the continuous scanning mode of the MR system (0.25 fps), the higher quality as well as the real time display (4 fps) of the MR images reconstructed from the 3D reference data allowed adequate hand-eye coordination. With our system, patient movement and tissue shifts could be immediately detected intraoperatively, and, in contrast to the standard procedure, navigation safely resumed after updating the reference data. The navigation system was characterized by good stability, efficient system integration and easy usability. Despite additional working steps still to be optimized, the duration of the image-guided brain tumor resections was not significantly longer. (orig.)

Full Text Available [english] Overestimating one's clinical competence can be dangerous to patient's safety. Therefore the goal of this study was to identify students with high confidence in their own clinical competence but low performance in objective assessment. 171 students in the 14 week course in internal medicine completed the clinical skills-related self-assessment expectations (SE and were tested in a 12 station OSCE. Both measures were obtained within three days. In total we identified 16% of students who overestimated their performance in clinical skills compared to their OSCE-results. Male students significantly more oversestimated their clinical compltence (31% than female students. One possible cause may be the lack of corrective experiences during clinical traineeship leading to the misconception of own performance. Further validation and the integration of a counselling program for these students seem necessary.

Injuries of the rotator cuff and the biceps tendon demonstrate different patterns, which can be recognized clinically and radiologically. These patterns are impingement syndrome with additional trauma, isolated trauma of the rotator cuff and shoulder dislocation causing rotator cuff tears. Furthermore, it is clinically crucial to evaluate the extent of a rotator cuff injury. Magnetic resonance imaging (MRI) is the modality of choice to differentiate these patterns. (orig.) [German] Bei der Verletzung von Rotatorenmanschette und Bizepssehne koennen verschiedene Muster klinisch und radiologisch erkannt werden.

Effective Dark Matter Halo Catalog in f(R) Gravity.

He, Jian-Hua; Hawken, Adam J; Li, Baojiu; Guzzo, Luigi

2015-08-14

We introduce the idea of an effective dark matter halo catalog in f(R) gravity, which is built using the effective density field. Using a suite of high resolution N-body simulations, we find that the dynamical properties of halos, such as the distribution of density, velocity dispersion, specific angular momentum and spin, in the effective catalog of f(R) gravity closely mimic those in the cold dark matter model with a cosmological constant (ΛCDM). Thus, when using effective halos, an f(R) model can be viewed as a ΛCDM model. This effective catalog therefore provides a convenient way for studying the baryonic physics, the galaxy halo occupation distribution and even semianalytical galaxy formation in f(R) cosmologies.

The signal vector is obtained and the space-time-frequency distribution matrix is formed by FrFT. Then, this distribution matrix is used instead of the traditional MUSIC covariance matrix to construct FrFT- MUSIC spectral function. Target speed is estimated by searching. Simulation results show that this algorithm has a high accuracy of parameter estimation and strong resistance to noise.

f(R) gravity, torsion and non-metricity

International Nuclear Information System (INIS)

Sotiriou, Thomas P

2009-01-01

For both f(R) theories of gravity with an independent symmetric connection (no torsion), usually referred to as Palatini f(R) gravity theories, and for f(R) theories of gravity with torsion but no non-metricity, called U4 theories, it has been shown that the independent connection can actually be eliminated algebraically, as long as this connection does not couple to matter. Remarkably, the outcome in both cases is the same theory, which is dynamically equivalent with an ω 0 = -3/2 Brans-Dicke theory. It is shown here that even for the most general case of an independent connection with both non-metricity and torsion, one arrives at exactly the same theory as in the more restricted cases. This generalizes the previous results and explains why assuming that either the torsion or the non-metricity vanishing ultimately leads to the same theory. It also demonstrates that f(R) actions cannot support an independent connection which carries dynamical degrees of freedom, irrespective of how general this connection is, at least as long as there is no connection-matter coupling.

Method of isotope separation by chemi-ionization

International Nuclear Information System (INIS)

Wexler, S.; Young, C.E.

1977-01-01

A method is disclosed for separating isotopes in an isotopic mixture by aerodynamically accelerating a gaseous compound to form a jet of molecules, and passing the jet through a stream of electron donor atoms whereby an electron transfer takes place, thus forming negative ions of the molecules. The molecular ions are then passed through a radiofrequency quadrupole mass filter to separate the specific isotopes. cThis method may be used for any compounds having a sufficiently high electron affinity to permit negative ion formation, and is especially useful for the separation of plutonium and uranium isotopes. 10 claims, 1 figure

Development of Streptomyces sp. FR-008 as an emerging chassis

Directory of Open Access Journals (Sweden)

Qian Liu

2016-09-01

Full Text Available Microbial-derived natural products are important in both the pharmaceutical industry and academic research. As the metabolic potential of original producer especially Streptomyces is often limited by slow growth rate, complicated cultivation profile, and unfeasible genetic manipulation, so exploring a Streptomyces as a super industrial chassis is valuable and urgent. Streptomyces sp. FR-008 is a fast-growing microorganism and can also produce a considerable amount of macrolide candicidin via modular polyketide synthase. In this study, we evaluated Streptomyces sp. FR-008 as a potential industrial-production chassis. First, PacBio sequencing and transcriptome analyses indicated that the Streptomyces sp. FR-008 genome size is 7.26 Mb, which represents one of the smallest of currently sequenced Streptomyces genomes. In addition, we simplified the conjugation procedure without heat-shock and pre-germination treatments but with high conjugation efficiency, suggesting it is inherently capable of accepting heterologous DNA. In addition, a series of promoters selected from literatures was assessed based on GusA activity in Streptomyces sp. FR-008. Compared with the common used promoter ermE*-p, the strength of these promoters comprise a library with a constitutive range of 60–860%, thus providing the useful regulatory elements for future genetic engineering purpose. In order to minimum the genome, we also target deleted three endogenous polyketide synthase (PKS gene clusters to generate a mutant LQ3. LQ3 is thus an “updated” version of Streptomyces sp. FR-008, producing fewer secondary metabolites profiles than Streptomyces sp. FR-008. We believe this work could facilitate further development of Streptomyces sp. FR-008 for use in biotechnological applications.

f(R) gravity cosmology in scalar degree of freedom

International Nuclear Information System (INIS)

Goswami, Umananda Dev; Deka, Kabita

2014-01-01

The models of f(R) gravity belong to an important class of modified gravity models where the late time cosmic accelerated expansion is considered as the manifestation of the large scale modification of the force of gravity. f(R) gravity models can be expressed in terms of a scalar degree of freedom by explicit redefinition of model's variable. Here we report about the study of the features of cosmological parameters and hence the cosmological evolution using the scalar degree of freedom of the f(R) = ξR n gravity model in the Friedmann-Lemaître-Robertson-Walker (FLRW) background

FK506 (tacrolimus), a macrolide compound with immunosuppressant activity, has been proven to have clinical importance and has been manufactured industrially since 1993 by using mutants with high FK506-production ability; these mutants have been developed from the wild strain Streptomyces tsukubaensis No. 9993. FR900525 is one of the by-products of FK506 production. However, there was no effective industrial method to separate FR900525 from FK506 due to the structural similarity between the two compounds. Therefore, reducing the level of FR900525 was a serious problem in the industrial strain A. In this study, we aimed to reduce the FR900525 production. We first determined that pipecolic acid level was a critical parameter for controlling FR900525 production in strain A. S-(2-Aminoethyl) l-cysteine (AEC)-resistant mutants has been reported to increase lysine productivity successfully in a variety of lysine-producing microorganisms. Therefore, next, we applied a selection of AEC-resistant mutants to enhance pipecolic acid biosynthesis. Finally, four AEC-resistant mutants were obtained from strain A using ultraviolet irradiation, and three of them showed less FR900525 productivity compared to the parental strain A. Our findings indicated that AEC resistance was effective phenotype marker for increasing pipecolic acid productivity and for reducing FR900525 production in S. tsukubaensis. Thus, our study provides an efficient method for reducing FR90025 level during FK506 biosynthesis. Copyright © 2017 The Society for Biotechnology, Japan. Published by Elsevier B.V.

This report explains some results of the multidimensional evaluation on various fast reactor cycle system concepts from an interim report of the 2nd phase of ''Feasibility Study on Commercialized FR Cycle System''. This method is designed to give more objective and more quantitative evaluations to clarify commercialized system candidate concepts. Here we brief current evaluation method from the five viewpoints of safety, economy, environment, resource and non-proliferation, with some trial evaluation results for some cycles consist of promising technologies in reactor, core and fuel, reprocessing and fuel manufacture. Moreover, we describe FR cycle deployment scenarios which describe advantages and disadvantages of the cycles from the viewpoints of uranium resource and radioactive waste based on long-term nuclear material mass flow analyses and advantages of the deployment of FR cycle itself from the viewpoints of the comparison with alternative power supplies as well as cost and benefit.

A=225 implantation for $^{221}$Fr source for TRIUMF atom trap

CERN Multimedia

The FrPNC Collaboration is mounting an atom trap for parity violation experiments and precision spectroscopy on francium atoms at TRIUMF's ISAC facility. We would like to use ISOLDE's capability of simultaneously implanting A=225 (while another experiment runs online) to make a long-lived source feeding $^{221}$Fr for tests of the trap. $^{225}$Ra $\\beta$-decays to $^{225}$Ac, which then $\\alpha$-decays, producing 100 keV $^{221}$Fr t$_{1/2}$= 4.8 minute recoils. The implanted A=225 source would be shipped to TRIUMF, where it would be held for several minutes at a time a few mm from the same yttrium foil that normally receives the ISAC beam. SRIM calculations imply that 20% of the $^{221}$Fr will be implanted in a 1 cm diameter spot on the yttrium. Then the yttrium foil is moved to the trap and heated to release the Fr atoms, just as in normal ISAC online operation. A test implantation will be done at 10$^{7}$/sec production for 1 day, testing whether carbon cracking on the implantation foil in the mass separ...

We construct an F(R) gravity theory corresponding to the Weyl invariant two scalar field theory. We investigate whether such F(R) gravity can have the antigravity regions where the Weyl curvature invariant does not diverge at the Big Bang and Big Crunch singularities. It is revealed that the divergence cannot be evaded completely but can be much milder than that in the original Weyl invariant two scalar field theory.

We investigate the corresponding relation between f(R) gravity and holographic dark energy. We introduce a type of energy density from f(R) that has the same role as holographic dark energy. We obtain the differential equation that specifies the evolution of the introduced energy density parameter based on a varying gravitational constant. We discover the relation for the equation of state parameter for low redshifts that contains varying G correction.

Cosmological reconstruction of realistic modified F(R) gravities

International Nuclear Information System (INIS)

Nojiri, Shin'ichi; Odintsov, Sergei D.; Saez-Gomez, Diego

2009-01-01

The cosmological reconstruction scheme for modified F(R) gravity is developed in terms of e-folding (or, redshift). It is demonstrated how any FRW cosmology may emerge from specific F(R) theory. The specific examples of well-known cosmological evolution are reconstructed, including ΛCDM cosmology, deceleration with transition to phantom superacceleration era which may develop singularity or be transient. The application of this scheme to viable F(R) gravities unifying inflation with dark energy era is proposed. The additional reconstruction of such models leads to non-leading gravitational correction mainly relevant at the early/late universe and helping to pass the cosmological bounds (if necessary). It is also shown how cosmological reconstruction scheme may be generalized in the presence of scalar field.

Fallbericht: Seltene Raumforderungen der Leiste in der klinischen Erscheinung inguinaler Hernien: eine seminomatöse Lymphknotenmetastase und ein Liposarkom des Samenstranges

Directory of Open Access Journals (Sweden)

Burger M

2005-01-01

Full Text Available Einleitung: Wir berichten über eine seminomatöse inguinale Lymphknotenmetastase und ein Liposarkom des Samenstranges, die sich klinisch als eine inguinale Hernie präsentierten. Kasuistik: Fall 1: Ein 53jähriger Patient wurde unter der Annahme einer inguinalen Hernie links in einer chirurgischen Abteilung operiert. Es fand sich eine Raumforderung, welche in der Schnellschnittuntersuchung den Befund einer seminomatösen Lymphknotenmetastase ergab. In der folgenden Abklärung ergab sich ein linksseitiges pT2-Seminom. Anamnestisch wurde vor 26 Jahren eine inguinale Varikozelektomie links vorgenommen. Fall 2: Ein 61jähriger Patient stellte sich mit einer schmerzlosen Raumforderung der rechten Leiste vor, die klinisch als inguinale Hernie imponierte und seit drei Jahren größenprogredient war. Die Ultraschall- und MRT-Befunde wurden als eine inguinale Hernie mit einem Peritonealfett enthaltenden Bruchsack gedeutet. Intraoperativ fand sich ein Liposarkom des Samenstranges. Schlußfolgerung: Trotz der Häufigkeit inguinaler Herniotomien sind überraschende maligne Raumforderungen selten. Man sollte diese Möglichkeit aber bei transskrotalen Eingriffen in der Anamnese und bei nicht eindeutig einzuordnenden Befunden differentialdiagnostisch bedenken. Inguinale Lymphknotenmetastasen testikulärer Neoplasien sind selten, in der Literatur ist ein eindeutiger Zusammenhang mit Eingriffen im Skrotal- und Leistenbereich beschrieben. Die klinische Erscheinung einer solchen als Leistenhernie ist bisher noch nicht beschrieben worden. Liposarkome des Samenstranges sind ebenfalls selten. Therapeutisch sollte eine radikale chirurgische Exzision und in Fällen unklarer Absetzungsränder eine Radiatio erfolgen. Lokalrezidive treten häufig und eventuell auch spät auf.

Diffuser Haarausfall und klinische Endokrinologie: Neue Erkenntnisse

Directory of Open Access Journals (Sweden)

Liptak J

2013-01-01

Full Text Available Diffuser Haarausfall ist ein häufiges Krankheitsbild in der täglichen Praxis, dessen Diagnostik allerdings oft eine Herausforderung darstellt. In den vergangenen 10 Jahren wurden große Fortschritte in der Erforschung der Effekte diverser Hormone erzielt. In murinen Haarfollikeln wird Corticoliberin (Corticotropin-releasing Hormone [CRH] mit einem Peak in der Anagenphase (Wachstumsphase exprimiert. Ein stressinduziert erhöhter CRH-Spiegel kann durch Aktivierung von Mastzellen zu erhöhtem Haarverlust führen. Melatonin wird ebenfalls im Haarfollikel exprimiert und wirkt dort auf unterschiedliche Rezeptoren. Besonders der nukleäre Retinoic Acid Receptor-(RAR- Related Orphan-Receptor alpha (RORα scheint regulatorisch auf haarzyklusabhängige Prozesse zu wirken und wird auch abhängig vom Haarzyklus exprimiert. Melatonin greift zudem in androgen- und östrogenvermittelte Signaltransduktionswege ein. Eine topische Anwendung von Melatonin kann zu einer Zunahme der Anagenhaare führen. Auch Leptin wird im Haarfollikel exprimiert und beeinflusst Haarwachstum und Hautregeneration durch Aktivierung von STAT3. Bei Mäusen konnte durch Leptin die Anagenphase induziert werden. Über den Zusammenhang zwischen androgenetischer Alopezie und Metabolischem Syndrom wurden zahlreiche widersprüchliche Daten veröffentlicht. Zuletzt wies eine große koreanische Studie eine positive Assoziation der Krankheitsbilder bei Frauen nach, jedoch nicht bei Männern. Prolaktin induziert den verfrühten Übergang zur Katagenphase, senkt die Proliferationsrate der Keratinozyten im Haarfollikel und steigert deren Apoptoserate. Eine zu Haarausfall führende Hyperprolaktinämie kann unter anderem durch diverse Medikamente, insbesondere typische und atypische Neuroleptika, hervorgerufen werden. Zahlreiche Studien an Mäusen konnten belegen, dass der Vitamin-D-Rezeptor (VDR eng mit dem Haarwachstum assoziiert ist. Dieser scheint den Haarzyklus unabhängig von seinen Liganden zu kontrollieren. Auch zur Rolle des Eisenhaushaltes bzw. des Ferritinspiegels existieren widersprüchliche Daten. Ein Ferritinwert 40 μg/l könnte mit verstärktem Haarausfall assoziiert sein. Unklar bleibt, ob eine Eisensubstitution in diesen Fällen zum Nachwachsen der Haare führt. Verschiedene Hormone können endokrin, autokrin oder parakrin vermittelt das Haarwachstum beeinflussen. Neue Studien können Aufschluss über das komplexe Zusammenspiel diverser Regelkreisläufe geben und mögliche zukünftige Therapiemöglichkeiten aufzeigen.

2003-01-01

The 21st century society will be facing growing demand of energy, global environmental issues and concerns about fossil fuel exhaustion. In this society, it is essential to seek for a sustainable energy system to solve these energy-related concerns. In order to find ways for solving these problems, 'Feasibility Study on Commercialized FR Cycle System' was launched in 1999 as a joint research project of JNC, electric utilities, JAERI, CRIEPI etc. This project aims to build promising FR cycle technologies for the 21st century. Now, we are in the second phase (JFY 2001-2005) of this project. At the end of the second phase, we will propose promising concepts through applying innovative technologies. We started this Feasibility Study with defining the development target, which ended in five items; safety, economy, environmental burden, resource utilization and nuclear non-proliferation. These items should also serve as basic viewpoints to evaluate achievements of the study. This paper describes how we evaluate FR cycle options to come up with the final promising candidates. This paper also describes a prospective scenario to introduce FR cycle system, which shows how the FR cycle will be replacing existing LWRs by using limited natural uranium resource and spent fuels.

The discussions on the connection between gravity and thermodynamics attract much attention recently. We consider a static self-gravitating perfect fluid system in f(R) gravity, which is an important theory could explain the accelerated expansion of the universe. We first show that the Tolman-Oppenheimer-Volkoff equation of f(R) theories can be obtained by thermodynamical method in spherical symmetric spacetime. Then we prove that the maximum entropy principle is also valid for f(R) gravity in general static spacetimes beyond spherical symmetry. The result shows that if the constraint equation is satisfied and the temperature of fluid obeys Tolmans law, the extrema of total entropy implies other components of gravitational equations. Conversely, if f(R) gravitational equation hold, the total entropy of the fluid should be extremum. Our work suggests a general and solid connection between f(R) gravity and thermodynamics.

Robust approach to f(R) gravity

International Nuclear Information System (INIS)

Jaime, Luisa G.; Patino, Leonardo; Salgado, Marcelo

2011-01-01

We consider metric f(R) theories of gravity without mapping them to their scalar-tensor counterpart, but using the Ricci scalar itself as an ''extra'' degree of freedom. This approach avoids then the introduction of a scalar-field potential that might be ill defined (not single valued). In order to explicitly show the usefulness of this method, we focus on static and spherically symmetric spacetimes and deal with the recent controversy about the existence of extended relativistic objects in certain class of f(R) models.

Galaxy-galaxy weak gravitational lensing in f(R) gravity

Science.gov (United States)

Li, Baojiu; Shirasaki, Masato

2018-03-01

We present an analysis of galaxy-galaxy weak gravitational lensing (GGL) in chameleon f(R) gravity - a leading candidate of non-standard gravity models. For the analysis, we have created mock galaxy catalogues based on dark matter haloes from two sets of numerical simulations, using a halo occupation distribution (HOD) prescription which allows a redshift dependence of galaxy number density. To make a fairer comparison between the f(R) and Λ cold dark matter (ΛCDM) models, their HOD parameters are tuned so that the galaxy two-point correlation functions in real space (and therefore the projected two-point correlation functions) match. While the f(R) model predicts an enhancement of the convergence power spectrum by up to ˜ 30 per cent compared to the standard ΛCDM model with the same parameters, the maximum enhancement of GGL is only half as large and less than 5 per cent on separations above ˜1-2 h-1 Mpc, because the latter is a cross-correlation of shear (or matter, which is more strongly affected by modified gravity) and galaxy (which is weakly affected given the good match between galaxy autocorrelations in the two models) fields. We also study the possibility of reconstructing the matter power spectrum by combination of GGL and galaxy clustering in f(R) gravity. We find that the galaxy-matter cross-correlation coefficient remains at unity down to ˜2-3 h-1 Mpc at relevant redshifts even in f(R) gravity, indicating joint analysis of GGL and galaxy clustering can be a powerful probe of matter density fluctuations in chameleon gravity. The scale dependence of the model differences in their predictions of GGL can potentially allows us to break the degeneracy between f(R) gravity and other cosmological parameters such as Ωm and σ8.

The holographic bound in the scalar-tensor and f(R) gravities

International Nuclear Information System (INIS)

Firouzjaee, J.T.

2013-01-01

The holographic bound has been extended to the different theory of gravities such as scalar-tensor gravity and f(R) gravity according to the Noether charge definition of the entropy for a black hole surface. We have introduced some popular examples of the flat FRW cosmology in order to investigate holographic bound in scalar-tensor and f(R) gravity. Using the holographic bound, we put an additional constraint on scalar-tensor gravity and the f(R) gravity parameters. We also discuss the transformation from Jordan frame to Einstein frame. (orig.)

In this paper, we investigate the late-time cosmic acceleration in mimetic f(R, T) gravity with the Lagrange multiplier and potential in a Universe containing, besides radiation and dark energy, a self-interacting (collisional) matter. We obtain through the modified Friedmann equations the main equation that can describe the cosmological evolution. Then, with several models from Q(z) and the well-known particular model f(R, T), we perform an analysis of the late-time evolution. We examine the behavior of the Hubble parameter, the dark energy equation of state and the total effective equation of state and in each case we compare the resulting picture with the non-collisional matter (assumed as dust) and also with the collisional matter in mimetic f(R, T) gravity. The results obtained are in good agreement with the observational data and show that in the presence of the collisional matter the dark energy oscillations in mimetic f(R, T) gravity can be damped.

The aim of this work was to realize and clinically evaluate an image fusion platform for the integration of preoperative MRI and fMRI data into the intraoperative images of an interventional MRI system with a focus on neurosurgical procedures. A vertically open 0.5 T MRI scanner was equipped with a dedicated navigation system enabling the registration of additional imaging modalities (MRI, fMRI, CT) with the intraoperatively acquired data sets. These merged image data served as the basis for interventional planning and multimodal navigation. So far, the system has been used in 70 neurosurgical interventions (13 of which involved image data fusion - requiring 15 minutes extra time). The augmented navigation system is characterized by a higher frame rate and a higher image quality as compared to the system-integrated navigation based on continuously acquired (near) real time images. Patient movement and tissue shifts can be immediately detected by monitoring the morphological differences between both navigation scenes. The multimodal image fusion allowed a refined navigation planning especially for the resection of deeply seated brain lesions or pathologies close to eloquent areas. Augmented intraoperative orientation and instrument guidance improve the safety and accuracy of neurosurgical interventions. (orig.)

Biokompatible Metalle

Science.gov (United States)

Ha, Suk-Woo; Wintermantel, Erich

Metalle als Implantatwerkstoffe werden in der Medizin für zwei Hauptanwendungen eingesetzt: für Prothesen des totalen Gelenkersatzes wie beispielsweise Hüft-, Knie- und Schulterprothesen und für Fixationselemente zur Stabilisierung von Frakturen. Beispiele hierfür sind Osteosyntheseplatten, Marknägel, Schrauben, Drähte und Stents. Eine der ersten Anwendungen von Metallen im menschlichen Körper war die Fixation von Fragmenten eines gebrochenen Humerus (Oberarmknochen) mit einem Metalldraht durch zwei französische Physiker im Jahr 1775 [1]. Ausführliche Untersuchungen zur Verträglichkeit von Metallen im menschlichen Körper wurden bereits im frühen 19. Jahrhundert durchgeführt. Von den untersuchten Werkstoffen verursachten die edlen Metalle wie Gold, Silber und Platin aufgrund ihrer Korrosionsbeständigkeit und Körperverträglichkeit die geringsten Reizungen im menschlichen Körper. Die klinische Anwendung der Edelmetalle war jedoch wegen der geringen mechanischen Eigenschaften beschränkt. Andere Metalle wie Messing, Kupfer oder Eisen wiesen vergleichsweise höhere Festigkeitswerte auf, sie waren jedoch aufgrund der geringen Korrosionsbeständigkeit und Biokompatibilität nicht für den klinischen Einsatz geeignet. Ein weiteres Problem stellte die Gefahr der Infektion durch unsterile Instrumente und Implantate dar. Gegen Ende des 19. Jahrhunderts hielt die antiseptische Operationsmethode Einzug in die Kliniken, die z. B. erfolgreiche Operationen mit Silberdraht ermöglichte.

The previously introduced class of two-parametric phenomenological inflationary models in general relativity in which the slow-roll assumption is replaced by the more general, constant-roll condition is generalized to the case of f(R) gravity. A simple constant-roll condition is defined in the original Jordan frame, and exact expressions for a scalaron potential in the Einstein frame, for a function f(R) (in the parametric form) and for inflationary dynamics are obtained. The region of the model parameters permitted by the latest observational constraints on the scalar spectral index and the tensor-to-scalar ratio of primordial metric perturbations generated during inflation is determined.

F(R Gravity’s Rainbow and Its Einstein Counterpart

Directory of Open Access Journals (Sweden)

S. H. Hendi

2016-01-01

Full Text Available Motivated by UV completion of general relativity with a modification of a geometry at high energy scale, it is expected to have an energy dependent geometry. In this paper, we introduce charged black hole solutions with power Maxwell invariant source in the context of gravity’s rainbow. In addition, we investigate two classes of F(R gravity’s rainbow solutions. At first, we study energy dependent F(R gravity without energy-momentum tensor, and then we obtain F(R gravity’s rainbow in the presence of conformally invariant Maxwell source. We study geometrical properties of the mentioned solutions and compare their results. We also give some related comments regarding thermodynamical behavior of the obtained solutions and discuss thermal stability of the solutions.

Cosmology of Horava-Lifshitz f(R) gravity

We discuss the cosmology of recently proposed Horava-Lifshitz f(R) gravity. In particular, we derive the modified Hubble equation that reduces to the standard HL gravity case in appropriate limit. We show how the bounce solutions in this theory are modified due to nonlinear effect of f(R) gravity. In addition we find that the solutions exist when the Universe can make turn around for large scale-factor. Therefore, in principle, the Universe in this set-up can show cyclic behavior. (orig.)

Constraining f(R gravity in solar system, cosmology and binary pulsar systems

Directory of Open Access Journals (Sweden)

Tan Liu

2018-02-01

Full Text Available The f(R gravity can be cast into the form of a scalar–tensor theory, and scalar degree of freedom can be suppressed in high-density regions by the chameleon mechanism. In this article, for the general f(R gravity, using a scalar–tensor representation with the chameleon mechanism, we calculate the parametrized post-Newtonian parameters γ and β, the effective gravitational constant Geff, and the effective cosmological constant Λeff. In addition, for the general f(R gravity, we also calculate the rate of orbital period decay of the binary system due to gravitational radiation. Then we apply these results to specific f(R models (Hu–Sawicki model, Tsujikawa model and Starobinsky model and derive the constraints on the model parameters by combining the observations in solar system, cosmological scales and the binary systems.

Existence of relativistic stars in f(R) gravity

International Nuclear Information System (INIS)

Upadhye, Amol; Hu, Wayne

2009-01-01

We refute recent claims in the literature that stars with relativistically deep potentials cannot exist in f(R) gravity. Numerical examples of stable stars, including relativistic (GM * /r * ∼0.1), constant density stars, are studied. As a star is made larger, nonlinear 'chameleon' effects screen much of the star's mass, stabilizing gravity at the stellar center. Furthermore, we show that the onset of this chameleon screening is unrelated to strong gravity. At large central pressures P>ρ/3, f(R) gravity, like general relativity, does have a maximum gravitational potential, but at a slightly smaller value: GM * /r * | max =0.345<4/9 for constant density and one choice of parameters. This difference is associated with negative central curvature R under general relativity not being accessed in the f(R) model, but does not apply to any known astrophysical object.

Inflation in the framework of f(R) modified gravity is revisited. We study the conditions that f(R) should satisfy in order to lead to a viable inflationary model in the original form and in the Einstein frame. Based on these criteria we propose a new logarithmic model as a potential candidate for f(R) theories aiming to describe inflation consistent with observations from Planck satellite (2015). The model predicts scalar spectral index 0.9615

Closed string tachyon driving f(R) cosmology

Wang, Peng; Wu, Houwen; Yang, Haitang

2018-05-01

To study quantum effects on the bulk tachyon dynamics, we replace R with f(R) in the low-energy effective action that couples gravity, the dilaton, and the bulk closed string tachyon of bosonic closed string theory and study properties of their classical solutions. The α' corrections of the graviton-dilaton-tachyon system are implemented in the f(R). We obtain the tachyon-induced rolling solutions and show that the string metric does not need to remain fixed in some cases. In the case with H( t=‑∞ ) = , only the R and R2 terms in f(R) play a role in obtaining the rolling solutions with nontrivial metric. The singular behavior of more classical solutions are investigated and found to be modified by quantum effects. In particular, there could exist some classical solutions, in which the tachyon field rolls down from a maximum of the tachyon potential while the dilaton expectation value is always bounded from above during the rolling process.

eindeutigen praedisponierenden Faktoren festzustellen. Die Zeitspanne zwischen dem ersten Auftreten der Symptome und der endgueltigen Diagnose ist in der Regel erheblich. Das klinische Bild ist oft unspezifisch und variabel, und die schwierige klinische Beurteilung kann darauf beruhen, dass es sich um einen relativ selten auftretenden Zustand handelt. Ausserdem ist die klinische Untersuchung der Sakroiliakalgelenke sehr problematisch. Die Diagnose basiert auf Anamnese und klinischen Befunden. Sie weisen zusammen mit Blutkultur und/oder einem ev. Gelenkspunktat auf eine Infektion im Sakroiliakalgelenk hin. Das haeufigste klinische Symptom bei bakteriellen Infektionen sind Schmerzen im unteren Teil der Wirbelsaeule oder im Gesaess. Mittels einer STIR-Sequenz, welche die Sakroiliakalgelenke gut darstellt, koennen Pathologien relativ einfach und aeusserst frueh entdeckt werden. Von allen bildgebenden Verfahren ist MRT daher die Methode der Wahl bezueglich Sensitivitaet und Spezifitaet. Falls eine MRT aufgrund geringer Verfuegbarkeit nicht durchfuehrbar ist, sollte als zweite Methode der Wahl die 3-Phasenknochenszintigraphie durchgefuehrt werden. Der konventionellen Roentgendiagnostik kommt weder in der Frueh- noch Verlaufsdiagnostik eine entscheidende Rolle zu. Eine CT-gefuehrte Gelenkpunktion kann in unklaren Faellen die diagnostische Treffsicherheit erhoehen. Eine Therapiekontrolle ist am besten mittels Tc99m Blutpool-Untersuchungen moeglich. Eine hochgradige klinische Verdachtsdiagnose und eine fruehe MRT-Untersuchung sind die wesentliche Voraussetzung fuer die exakte Diagnose einer bakteriellen Sakroiliitis. (orig.)

Distinguishing f(R) theories from general relativity by gravitational lensing effect

The post-Newtonian formulation of a general class of f(R) theories is set up in a third-order approximation. It turns out that the information of a specific form of f(R) gravity is encoded in the Yukawa potential, which is contained in the perturbative expansion of the metric components. Although the Yukawa potential is canceled in the second-order expression of the effective refraction index of light, detailed analysis shows that the difference of the lensing effect between the f(R) gravity and general relativity does appear at the third order when √(f''(0)/f{sup '}(0)) is larger than the distance d{sub 0} to the gravitational source. However, the difference between these two kinds of theories will disappear in the axially symmetric spacetime region. Therefore only in very rare case the f(R) theories are distinguishable from general relativity by gravitational lensing effect in a third-order post-Newtonian approximation. (orig.)

2002-07-01

This report is intended to explain the outline of the research and development (R and D) in the FY 2001 on cost-benefit analysis of FR (Fast Reactor) cycle system concepts. The work was conducted as a part of the JNC's Feasibility Study on Commercialized Fast Reactor Cycle Systems (the F/S)'. In the FY 2001, the work conducted in the JNC was summed up as the followings: Conceptual study on cost-benefit analysis for FR cycle R and D. Refinement on the evaluation procedure and improvement over operation efficiency. Cost-benefit analysis of the reference FR cycle and sensitivity analysis with the revised system. Cost-benefit analyses of R and Ds for various FR cycle candidate concepts including FR cycle concepts studied in the F/S phase 1. The work made it possible to evaluate the cost effectiveness of various FR cycle systems efficiently. The cost-benefit analysis, which is often used for the policy evaluation, is considered to be applicable to FR cycle system concepts in the F/S. (author)

A no-hair theorem for black holes in f(R) gravity

Science.gov (United States)

Cañate, Pedro

2018-01-01

In this work we present a no-hair theorem which discards the existence of four-dimensional asymptotically flat, static and spherically symmetric or stationary axisymmetric, non-trivial black holes in the frame of f(R) gravity under metric formalism. Here we show that our no-hair theorem also can discard asymptotic de Sitter stationary and axisymmetric non-trivial black holes. The novelty is that this no-hair theorem is built without resorting to known mapping between f(R) gravity and scalar–tensor theory. Thus, an advantage will be that our no-hair theorem applies as well to metric f(R) models that cannot be mapped to scalar–tensor theory.

Disentangling the f(R). Duality

International Nuclear Information System (INIS)

Broy, Benedict J.; Westphal, Alexander; Pedro, Francisco G.; Univ. Autonoma de Madrid

2014-11-01

Motivated by UV realisations of Starobinsky-like inflation models, we study generic exponential plateau-like potentials to understand whether an exact f(R)-formulation may still be obtained when the asymptotic shift-symmetry of the potential is broken for larger field values. Potentials which break the shift symmetry with rising exponentials at large field values only allow for corresponding f(R)-descriptions with a leading order term R n with 1 2 -term survives as part of a series expansion of the function f(R) and thus cannot maintain a plateau for all field values. We further find a lean and instructive way to obtain a function f(R) describing m 2 φ 2 -inflation which breaks the shift symmetry with a monomial, and corresponds to effectively logarithmic corrections to an R+R 2 model. These examples emphasise that higher order terms in f(R)-theory may not be neglected if they are present at all. Additionally, we relate the function f(R) corresponding to chaotic inflation to a more general Jordan frame set-up. In addition, we consider f(R)-duals of two given UV examples, both from supergravity and string theory. Finally, we outline the CMB phenomenology of these models which show effects of power suppression at low-l.

Reconstructing an f(R) model from holographic dark energy: using the observational evidence

International Nuclear Information System (INIS)

Saaidi, Kh; Aghamohammadi, A

2012-01-01

We investigate the correspondence relation between f(R) gravity and an interacting holographic dark energy (HDE). By obtaining the conditions needed for some observational evidence such as positive acceleration expansion of the Universe, crossing the phantom divide line and validity of the thermodynamics second law in an interacting HDE model and corresponding it with the f(R) model of gravity, we find a viable f(R) model that can explain the present Universe. We also obtain the explicit evolutionary forms of the corresponding scalar field, potential and scale factor of the Universe. (paper)

LOW-POWER RADIO GALAXIES IN THE DISTANT UNIVERSE: A SEARCH FOR FR I AT 1 < z < 2 IN THE COSMOS FIELD

International Nuclear Information System (INIS)

Chiaberge, Marco; Tremblay, Grant; Macchetto, F. Duccio; Sparks, W. B.; Capetti, Alessandro; Tozzi, Paolo

2009-01-01

We present a search for FR I radio galaxies between 1 < z < 2 in the COSMOS field. In absence of spectroscopic redshift measurements, the selection method is based on multiple steps which make use of both radio and optical constraints. The basic assumptions are that (1) the break in radio power between low-power FR Is and the more powerful FR IIs does not change with redshift, and (2) that the photometric properties of the host galaxies of low-power radio galaxies in the distant universe are similar to those of FR IIs in the same redshift bin, as is the case for nearby radio galaxies. We describe the results of our search, which yields 37 low-power radio galaxy candidates that are possibly FR Is. We show that a large fraction of these low-luminosity radio galaxies display a compact radio morphology that does not correspond to the FR I morphological classification. Furthermore, our objects are apparently associated with galaxies that show clear signs of interactions, at odds with the typical behavior observed in low-z FR I hosts. The compact radio morphology might imply that we are observing intrinsically small and possibly young objects that will eventually evolve into the giant FR Is we observe in the local universe. One of the objects appears as pointlike in Hubble Space Telescope (HST) images. This might belong to a population of FR I-QSOs, which however would represent a tiny minority of the overall population of high-z FR Is. As for the local FR Is, a large fraction of our objects are likely to be associated with groups or clusters, making them 'beacons' for high-redshift clusters of galaxies. Our search for candidate high-z FR Is we present in this paper constitutes a pilot study for objects to be observed with future high-resolution and high-sensitivity instruments such as the EVLA and ALMA in the radio band, HST/WFC3 in the optical and IR, James Webb Space Telescope in the IR, as well as future generation X-ray satellites.

Full Text Available This study focuses on isolation, screening and characterization of novel probiotics from gastrointestinal tract of free-range chicken (Gallus gallus domesticus. Fifty seven colonies were isolated and three isolates (FR4, FR9 and FR12 were selected and identified as Lactobacillus gasseri FR4, Bacillus tequilensis FR9 and L. animalis FR12 by 16S rRNA sequencing. Three strains were able to survive in stimulated acidic and bile conditions and inhibit the growth of pathogens. Especially, FR9 exhibited maximum inhibition against Listeria monocytogenes and none of them exhibited hemolytic activity. Native-PAGE revealed the presence of low molecular weight (3.4-5.0 KDa antimicrobial peptide. The peptide was further purified by Sephadex G-50 column and RP-HPLC using C18 column. N-terminal amino acid sequencing of antimicrobial peptide showed 100% consensus to antilisterial peptide SubtilosinA and SboA gene was amplified from FR9 genome. FR9 showed maximum aggregation activity, EPS production (85.46 mg/L and cholesterol assimilation (63.12 ± 0.05 µg/mL. Strong adhesion property (12.6% and pathogen invasion protection ability was revealed by B. tequilensis FR9 towards HCT-116 human colon carcinoma cell line. This is the first study to demonstrate antilisterial SubtilosinA production of B. tequilensis. Our results indicate that B. tequilensis FR9 strain furnish the essential characteristics of a potential probiotics and might be incorporated into human and animal food supplements.

Unifying inflation with dark energy in modified F(R) Horava-Lifshitz gravity

International Nuclear Information System (INIS)

Elizalde, E.; Saez-Gomez, D.; Nojiri, S.; Odintsov, S.D.

2010-01-01

We study FRW cosmology for a non-linear modified F(R) Horava-Lifshitz gravity which has a viable convenient counterpart. A unified description of early-time inflation and late-time acceleration is possible in this theory, but the cosmological dynamic details are generically different from the ones of the convenient viable F(R) model. Remarkably, for some specific choice of parameters they do coincide. The emergence of finite-time future singularities is investigated in detail. It is shown that these singularities can be cured by adding an extra, higher-derivative term, which turns out to be qualitatively different when compared with the corresponding one of the convenient F(R) theory.

Full Text Available We have computed the number of polarization modes of gravitational waves propagating in the Minkowski background in f(R gravity. These are three of two from transverse-traceless tensor modes and one from a massive trace mode, which confirms the results found in the literature. There is no massless breathing mode and the massive trace mode corresponds to the Ricci scalar. A newly defined metric tensor in f(R gravity satisfies the transverse-traceless (TT condition as well as the TT wave equation.

The coincidence problem in holographic f(R) gravity

It is well known that f(R) gravity models formulated in the Einstein conformal frame are equivalent to Einstein gravity together with a minimally coupled scalar field. In this case, the scalar field couples with the matter sector and the coupling term is given by the conformal factor. We apply the holographic principle to such interacting models. In a spatially flat universe, we show that the Einstein frame representation of f(R) models leads to a constant ratio of energy densities of dark matter to dark energy.

Constraint on reconstructed f(R) gravity models from gravitational waves

Science.gov (United States)

Lee, Seokcheon

2018-06-01

The gravitational wave (GW) detection of a binary neutron star inspiral made by the Advanced LIGO and Advanced Virgo paves the unprecedented way for multi-messenger observations. The propagation speed of this GW can be scrutinized by comparing the arrival times between GW and neutrinos or photons. It provides the constraint on the mass of the graviton. f(R) gravity theories have the habitual non-zero mass gravitons in addition to usual massless ones. Previously, we show that the model independent f(R) gravity theories can be constructed from the both background evolution and the matter growth with one undetermined parameter. We show that this parameter can be constrained from the graviton mass bound obtained from GW detection. Thus, the GW detection provides the invaluable constraint on the validity of f(R) gravity theories.

Herbert Fröhlich a physicist ahead of his time

Hyland, G J

2015-01-01

This biography provides a stimulating and coherent blend of scientific and personal narratives describing the many achievements of the theoretical physicist Herbert Fröhlich. For more than half a century, Fröhlich was an internationally renowned and much respected figure who exerted a decisive influence, often as a ‘man ahead of his time’, in fields as diverse as meson theory and biology. Although best known for his contributions to the theory of dielectrics and superconductivity, he worked in many other fields, his most important legacy being the pioneering introduction quantum field-theoretical methods into condensed matter physics in 1952, which revolutionised the subsequent development of the subject. Gerard Hyland has written an absorbing and informative account, in which Herbert Fröhlich’s magnetic personality shines through.

f(R in Holographic and Agegraphic Dark Energy Models and the Generalized Uncertainty Principle

Directory of Open Access Journals (Sweden)

Barun Majumder

2013-01-01

Full Text Available We studied a unified approach with the holographic, new agegraphic, and f(R dark energy model to construct the form of f(R which in general is responsible for the curvature driven explanation of the very early inflation along with presently observed late time acceleration. We considered the generalized uncertainty principle in our approach which incorporated the corrections in the entropy-area relation and thereby modified the energy densities for the cosmological dark energy models considered. We found that holographic and new agegraphic f(R gravity models can behave like phantom or quintessence models in the spatially flat FRW universe. We also found a distinct term in the form of f(R which goes as R 3 / 2 due to the consideration of the GUP modified energy densities. Although the presence of this term in the action can be important in explaining the early inflationary scenario, Capozziello et al. recently showed that f(R ~ R 3 / 2 leads to an accelerated expansion, that is, a negative value for the deceleration parameter q which fits well with SNeIa and WMAP data.

2011-04-29

The four-dimensional metric f(R) theories of gravity are cast into connection-dynamical formalism with real su(2) connections as configuration variables. Through this formalism, the classical metric f(R) theories are quantized by extending the loop quantization scheme of general relativity. Our results imply that the nonperturbative quantization procedure of loop quantum gravity is valid not only for general relativity but also for a rather general class of four-dimensional metric theories of gravity.

We select f(R) gravity models that undergo scale factor duality transformations. As a starting point, we consider the tree-level effective gravitational action of bosonic String Theory coupled with the dilaton field. This theory inherits the Busher's duality of its parent String Theory. Using conformal transformations of the metric tensor, it is possible to map the tree-level dilaton-graviton string effective action into f(R) gravity, relating the dilaton field to the Ricci scalar curvature. Furthermore, the duality can be framed under the standard of Noether symmetries and exact cosmological solutions are derived. Using suitable changes of variables, the string-based f(R) Lagrangians are shown in cases where the duality transformation becomes a parity inversion.

Quality of life (QoL) is an important factor in patient care. This analysis is focused on QoL before and after radio(chemo)therapy in patients with thoracic carcinomas, as well as on its influence on clinical follow-up and survival, and the correlation with treatment-related toxicities. The analysis included 81 patients with intrathoracic carcinoma receiving radio(chemo)therapy. For analysis of QoL, the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and the lung cancer-specific supplement (EORTC QLQ-LC13) were used. QoL data were collected before radiation treatment (RT), and 6 weeks, 12 weeks, 6 months, and 12 months after RT. Other factors were additionally analyzed, including clinical outcome, survival, and side effects. The functional scales showed maximum values or at least a recovery 12 weeks after RT. Symptoms with a high mean symptom score (> 40) at all appointments were fatigue, dyspnea, and coughing. Insomnia, peripheral neuropathy, appetite loss, dyspnea (from QLQ-LC13), and all pain parameters had an intermediate mean score (10-40). There were low mean scores of < 10 for nausea and vomiting, diarrhea, sore mouth, and hemoptysis. There was a significant correlation between clinical dysphagia and radiation pneumonitis with the associated symptom scales. None of the QoL scores had a significant influence on local and distant control or survival. 12 weeks after RT the QLQ-C30 functional scales show the highest scores or at least a temporary recovery. The symptom scales accurately reflect the common symptoms and treatment-related toxicities. QoL did not prove to be a significant predictor for local and distant control or survival. (orig.)

Aim: To prove that bilateral hereditary micro-epiphyseal dysplasia (BHMED), first described by Elsbach in 1959, is a distinct disorder radiologically as well as clinically, compared with multiple epiphyseal dysplasia (MED). Material and Methods: We used the data of the revised pedigree with 84 family members, performed a medical history, physical examination and made a radiological evaluation for defining a clinical and radiological phenotype of BHMED family members. We used blood samples for genetic analysis. Results: Although there is a clear clinical picture of the dysplasia, the radiological signs are more reliable for making the diagnosis. Especially the typical deformity of the hip and knee joint are diagnostic for BHMED. By linkage analysis we excluded linkage with the three known MED-loci (EDM1, EDM2 and EDM3). Conclusion: BHMED is indeed an entity that is distinct from common multiple epiphyseal dysplasia (MED), clinically, as well as radiologically and genetically. (orig.) [German] Ziel: Es sollte dargelegt werden, dass sich eine vererbliche, laterale Mikro-Epiphysendysplasie (BHMED), Erstbeschreibung durch Elsbach 1959, klinisch, radiologisch und genetisch von einer mutiplen Epiphysendysplasie (MED) unterscheidet. Material und Methode: Anhand der Daten eines ueberarbeiteten Stammbaumes mit 84 Familienmitgliedern wurde der medizinische Werdegang rekonstruiert. Es erfolgte eine physische Untersuchung der Familienmitglieder. Schliesslich wurde eine radiologische Auswertung durchgefuehrt, um einen klinischen und radiologischen Phaenotyp der von BHMED betroffenen Familienmitglieder zu definieren. Fuer eine genetische Analyse wurden Blutproben entnommen. Ergebnisse: Obwohl es ein deutliches klinisches Bild einer Dysplasie gibt, sind die radiologischen Kennzeichen fuer die Diagnose zuverlaessiger. Insbesondere die typische Deformation der Huefte und des Kniegelenks ist diagnostisch fuer BHMED. Durch Linkage-Analyse konnte eine Verbindung zu den drei bekannten

Patients with Klatskin's tumour present clinically unspecific symptoms such as painless jaundice and cholangitic discomfort. The only curative treatment is R0 resection of the tumour. To allow stage-specific therapy, accurate tumour staging is indispensable, the first step of which is abdominal sonography. If there is a suspect finding, cross-sectional imaging techniques like MRI or MDR-CT are used to clarify or stage the lesion, respectively. To estimate resectability, MRI together with MRC and MRI angiography are superior to MDR-CT. Biopsy using ERC is required before starting any specific treatment. If therapeutically relevant peritoneal carcinosis is clinically suspected although not radiologically confirmed, PET should also be performed. The value of PET/CT has to be evaluated in further studies. For optimal treatment, close cooperation between clinicians and radiologists is necessary. (orig.) [German] Patienten mit Klatskin-Tumoren werden klinisch durch unspezifische Symptome wie z. B. schmerzloser Ikterus oder cholangitische Beschwerden auffaellig. Eine R0-Resektion ist der einzige kurative Therapieansatz. Um eine stadiengerechte Therapie zu ermoeglichen, muss ein moeglichst exaktes Tumorstaging erfolgen. Primaer kommt die abdominelle Sonographie zum Einsatz. Zur Abklaerung eines unklaren Sonographiebefundes sowie zum Staging eines suspizierten Tumors werden Schnittbildverfahren MRT und MDR-CT benoetigt. Zur Beurteilung der lokalen Tumorresektabilitaet ist die MRT in Zusammenschau mit der MRC sowie MR-Angiographie der MDR-CT ueberlegen. Vor Einleitung einer Therapie sollte auf jeden Fall die Verdachtsdiagnose eines Klatskin-Tumors bioptisch mittels ERC gesichert werden. Wird klinisch trotz negativem Nachweis einer Peritonealkarzinose eine solche suspiziert, sollte bei Therapierelevanz (z. B. bei ansonsten fehlendem Nachweis einer Fernmetastasierung) eine PET ergaenzend durchgefuehrt werden. Der zukuenftige Stellenwert der PET/CT muss in weiteren Studien

The Einstein static (ES) universe has played a major role in various emergent scenarios recently proposed in order to cure the problem of the initial singularity of the standard model of cosmology. In the model we address, we study the existence and stability of an ES universe in the context of f(R, T) modified theories of gravity. Considering specific forms of the f(R, T) function, we seek for the existence of solutions representing ES state. Using dynamical system techniques along with numerical analysis, we find two classes of solutions: the first one is always unstable of the saddle type, while the second is always stable so that its dynamical behavior corresponds to a center equilibrium point. The importance of the second class of solutions is due to the significant role they play in constructing non-singular emergent models in which the universe could have experienced past-eternally a series of infinite oscillations about such an initial static state after which it enters, through a suitable physical mechanism, to an inflationary era. Considering specific forms for the functionality of f(R, T), we show that this theory is capable of providing cosmological solutions which admit emergent universe (EU) scenarios. We also investigate homogeneous scalar perturbations for the mentioned models. The stability regions of the solutions are parametrized by a linear equation of state (EoS) parameter and other free parameters that will be introduced for the models. Our results suggest that modifications in f(R, T) gravity would lead to stable solutions which are unstable in f(R) gravity model. (orig.)

Generation of spherically symmetric metrics in f(R) gravity

In D-dimensional spherically symmetric f(R) gravity there are three unknown functions to be determined from the fourth order differential equations. It is shown that the system remarkably may be integrated to relate two functions through the third one to provide a reduction to second order equations accompanied with a large class of potential solutions. The third function, which acts as the generator of the process, is F(R) = (df(R))/(dR). We recall that our generating function has been employed as a scalar field with an accompanying self-interacting potential previously, which is entirely different from our approach. Reduction of f(R) theory into a system of equations seems to be efficient enough to generate a solution corresponding to each generating function. As particular examples, besides the known ones, we obtain new black hole solutions in any dimension D. We further extend our analysis to cover non-zero energy-momentum tensors. Global monopole and Maxwell sources are given as examples. (orig.)

Probing the f(R) formalism through gravitational wave polarizations

International Nuclear Information System (INIS)

The direct observation of gravitational waves (GW) in the near future, and the corresponding determination of the number of independent polarizations, is a powerful tool to test general relativity and alternative theories of gravity. In the present work we use the Newman-Penrose formalism to characterize GWs in quadratic gravity and in a particular class of f(R) Lagrangians. We find that both quadratic gravity and the f(R) theory belong to the most general invariant class of GWs, i.e., they can present up to six independent polarizations of GWs. For a particular combination of the parameters, we find that quadratic gravity can present up to five polarizations states. On the other hand, if we use the Palatini approach for f(R) theories, GWs present only the usual two transverse-traceless polarizations such as in general relativity. Thus, we conclude that the observation of GWs can strongly constrain the suitable formalism for these theories.

The existence of a non-zero electric dipole moment (EDM) implies the violation of time reversal symmetry. As the time-reversal symmetry violation predicted by the Standard Model (SM) for the electron EDM is too small to be observed with current experimental techniques and any a non-zero EDM would indicate new physics beyond the SM. The tiny signal from the electron EDM is enhanced in the heavy atoms such as francium (Fr). We are constructing the laser-cooled Fr factory to search for the electron EDM.

Reduction of environmental impact by FR cycle deployment

2005-03-01

In this report radioactive waste generations in terms of disposal volume or disposal field equivalent, and the radioactive toxicity of HLW are evaluated to clarify the promising nuclear scenario for the sake of realization of sustainable society in 21st century. This analysis was conducted based on the outcomes of the mass flow evaluation tool 'FAMILY-21' which calculates a material balance for TRU in the following scenarios. 1) LWR once-through scenario, 2) Pu partly recycling in LWR scenario, 3) Pu full recycling in LWR scenario, 4) FBR deployment scenario, 5) Interim storage scenario. The result shows that the cumulative area of low level radioactive waste (LLW) disposal field at 2150 in the FR cycle deployment scenario is 1.8 times larger than that in the LWR once-through scenario. The area of LLW disposal field at 2150 is a few km 2 in all the scenarios. In contrast, the cumulative area of high level radioactive waste (HLW) disposal field at 2150 in the FR cycle deployment scenario is less than half of that in the LWR once-through scenario. The area of HLW disposal field at 2150 is about 10 times of the area of LLW disposal field. Moreover, the FR deployment reduces the radioactive toxicity of HLW by U/TRU recycling, and shortens the period to decay under the natural Uranium toxicity level. Considering the area of radioactive waste disposal field and the radioactive toxicity of HLW, the advantage of the FR cycle deployment is indicated quantitatively from the viewpoint of the environmental burden reduction.

Das biochemische Rezidiv beim Prostatakarzinom

Directory of Open Access Journals (Sweden)

Rauchenwald M

2010-01-01

Full Text Available Als biochemisches Rezidiv (BCR wird der Wiederanstieg des nach kurativer Therapie des Prostatakarzinoms (PCa abgefallenen PSA-Werts bezeichnet. Der PSA-Verlauf nach kurativer Therapie ist von der primären Behandlungsmethode abhängig, weshalb auch unterschiedliche Definitionen dafür vorliegen. Der Verlauf selbst scheint prognostische Bedeutung zu haben. Ein Wiederanstieg des PSA-Werts geht der klinischen Progression voraus, wodurch frühzeitig eine Therapie eingeleitet werden kann. Der ideale Zeitpunkt für eine Sekundärbehandlung ist allerdings noch ungenügend definiert. Fast die Hälfte der BCR treten innerhalb der ersten 2 Jahre, ¾ innerhalb der ersten 5 Jahre nach Primärtherapie auf. Als Risikofaktoren für einen BCR werden ein primäres Tumorstadium ≥ T2c, PSA 15, Samenblaseninvasion, Lymphknotenbefall sowie Gleason-Score ≥ 8 angesehen. Von klinischer Bedeutung ist vor allem die Unterscheidung zwischen lokoregionärem und systemischem Rezidiv. Hierzu werden als Parameter neben dem primären Tumorstadium und Gleason-Score das posttherapeutische Intervall und die PSA-Dynamik empfohlen. Als diagnostische Maßnahmen erscheinen nur die Skelettszintigraphie und die Positronenemissionstomographie mit Acetat- oder Cholintracern und diese ebenfalls nur bei entsprechend hohen PSA-Werten sinnvoll. Therapeutisch kommt nach primärer Radikaloperation und Verdacht auf einen lokalen Progress in erster Linie die Salvagebestrahlung zur Anwendung, nach primärer Radiatio wird allerdings vorwiegend die hormonelle Manipulation einer Salvageoperation oder alter“nativen lokaltherapeutischen Maßnahmen vorgezogen.

FR4-based electromagnetic energy harvester for wireless sensor nodes

Hatipoglu, G.; Ürey, H.

Electromagnetic (EM) energy harvesting seems to be one of the most promising ways to power wireless sensors in a wireless sensor network. In this paper, FR4, the most commonly used PCB material, is utilized as a mechanical vibrating structure for EM energy harvesting for body-worn sensors and intelligent tire sensors, which involve impact loadings. FR4 can be a better material for such applications compared to silicon MEMS devices due to lower stiffness and broadband response. In order to demonstrate FR4 performance and broadband response, three moving magnet type EM generator designs are developed and investigated throughout the paper. A velocity-damped harvester simulation model is first developed, including a detailed magnetic model and the magnetic damping effects. The numerical results agree well with the experimental results. Human running acceleration at the hip area that is obtained experimentally is simulated in order to demonstrate system performance, which results in a scavenged power of about 40 µW with 15 m s-2 acceleration input. The designed FR4 energy scavengers with mechanical stoppers implemented are particularly well suited for nearly periodic and non-sinusoidal high- g excitations with rich harmonic content. For the intelligent tire applications, a special compact FR4 scavenger is designed that is able to withstand large shocks and vibrations due to mechanical shock stoppers built into the structure. Using our design, 0.4 mW power across a load resistance at off-resonance operation is obtained in shaker experiments. In the actual operation, the tangential accelerations as a result of the tire-road contact are estimated to supply power around 1 mW with our design, which is sufficient for powering wireless tire sensors. The normalized power density (NPD) of the designed actuators compares favorably with most actuators reported in the literature.

Electromagnetic (EM) energy harvesting seems to be one of the most promising ways to power wireless sensors in a wireless sensor network. In this paper, FR4, the most commonly used PCB material, is utilized as a mechanical vibrating structure for EM energy harvesting for body-worn sensors and intelligent tire sensors, which involve impact loadings. FR4 can be a better material for such applications compared to silicon MEMS devices due to lower stiffness and broadband response. In order to demonstrate FR4 performance and broadband response, three moving magnet type EM generator designs are developed and investigated throughout the paper. A velocity-damped harvester simulation model is first developed, including a detailed magnetic model and the magnetic damping effects. The numerical results agree well with the experimental results. Human running acceleration at the hip area that is obtained experimentally is simulated in order to demonstrate system performance, which results in a scavenged power of about 40 µW with 15 m s −2 acceleration input. The designed FR4 energy scavengers with mechanical stoppers implemented are particularly well suited for nearly periodic and non-sinusoidal high- g excitations with rich harmonic content. For the intelligent tire applications, a special compact FR4 scavenger is designed that is able to withstand large shocks and vibrations due to mechanical shock stoppers built into the structure. Using our design, 0.4 mW power across a load resistance at off-resonance operation is obtained in shaker experiments. In the actual operation, the tangential accelerations as a result of the tire–road contact are estimated to supply power around 1 mW with our design, which is sufficient for powering wireless tire sensors. The normalized power density (NPD) of the designed actuators compares favorably with most actuators reported in the literature

Full Text Available Die Akkumulation von Knorpel- und Knochenschäden, wie sie für chronisch-destruktive Arthritisformen typisch ist, kann durch frühzeitige Intervention mit wirksamen Medikamenten verzögert oder verhindert werden. Voraussetzung ist die rechtzeitige Übernahme der Betreuung gefährdeter Patienten durch einen in der speziellen rheumatologischen Diagnostik und Therapie bewanderten Arzt. Dieser muß das gesamte Repertoire der Arthritistherapie (Medikamente, ergotherapeutische und physiotherapeutische Maßnahmen, Patientenaufklärung etc. entsprechend dem „State of the Art“ beherrschen. In den letzten Jahren erfolgte in vielen Ländern die Etablierung von Spezialeinrichtungen für Patienten mit früher Arthritis. Die an diesen Patienten gewonnenen Erkenntnisse deuten darauf hin, daß die „kritische Periode“, innerhalb derer eine chronische Arthritis möglicherweise reversibel ist, bei 6 bis 12 Wochen liegt.

2017-09-01

We study scalar field FLRW cosmology in the content of f(R) gravity. Our consideration is restricted to the spatially flat Friedmann universe. We derived the general evolution equations of the model, and showed that the scalar field equation is automatically satisfied for any form of the f(R) function. We also derived representations for kinetic and potential energies, as well as for the acceleration in terms of the Hubble parameter and the form of the f(R) function. Next we found the exact cosmological solutions in modified gravity without specifying the f(R) function. With negligible acceleration of the scalar curvature, we found that the de Sitter inflationary solution is always attained. Also we obtained new solutions with special restrictions on the integration constants. These solutions contain oscillating, accelerating, decelerating and even contracting universes. For further investigation, we selected special cases which can be applied with early or late inflation. We also found exact solutions for the general case for the model with negligible acceleration of the scalar curvature in terms of special Airy functions. Using initial conditions which represent the universe at the present epoch, we determined the constants of integration. This allows for the comparison of the scale factor in the new solutions with that for current stage of the universe evolution in the ΛCDM model.

The first observation of the prompt and the delayed γ transitions involving the high spin states in 210 Fr is reported. The decay of the high spin states and the isomeric levels of 210 Fr, identified for the first time from the known sequence of low-lying transitions found earlier in the α decay of 214 Ac, were studied. High spin states of the doubly-odd 210 Fr, which were produced by the fusion evaporation reaction 197 Au ( 16 O, xn) 213-x Fr, were populated and the subsequent emitted γ rays were detected through the high-sensitivity germanium clover detector array INGA. The level scheme up to yrast levels of 5.3 MeV excitation energy and ∼20(ℎ/2π) angular momentum could be established for the first time through γγ, γγΔT coincidence, and DCO ratio measurements. A new low-lying isomeric transition at E γ = 203(2) keV was observed. The half-life was measured to be T 1/2 = 41(2) ns. The measured half-life was compared with the corresponding single-particle estimate, based on the level scheme obtained from the experiment.

In this work we investigate the equilibrium configurations of white dwarfs in a modified gravity theory, namely, f(R, T) gravity, for which R and T stand for the Ricci scalar and trace of the energy-momentum tensor, respectively. Considering the functional form f(R, T) = R+2λT, with λ being a constant, we obtain the hydrostatic equilibrium equation for the theory. Some physical properties of white dwarfs, such as: mass, radius, pressure and energy density, as well as their dependence on the parameter λ are derived. More massive and larger white dwarfs are found for negative values of λ when it decreases. The equilibrium configurations predict a maximum mass limit for white dwarfs slightly above the Chandrasekhar limit, with larger radii and lower central densities when compared to standard gravity outcomes. The most important effect of f(R, T) theory for massive white dwarfs is the increase of the radius in comparison with GR and also f(R) results. By comparing our results with some observational data of massive white dwarfs we also find a lower limit for λ, namely, λ > -3 x 10{sup -4}. (orig.)

100-FR-3 groundwater/soil gas supplemental limited field investigation report

International Nuclear Information System (INIS)

1996-04-01

In 1993, a Limited Field Investigation (LFI) was conducted for the 100-FR-3 Operable Unit which identified trichloroethylene (TCE) as a contaminant of potential concern (COPC) (DOE-RL 1994). In groundwater samples collected for the LFI, TCE was detected in well 199-177-1 at a concentration exceeding the U.S. Environmental Protection Agency (EPA) maximum contaminant level (5 μg/L) and Washington State groundwater criteria (3 μg/L). With the concurrence of the EPA and the Washington State Department of Ecology (Ecology), a supplemental LFI was conducted to determine the extent and potential source of TCE groundwater contamination associated with the 100-FR-3 Operable Unit. This report summarizes the activities and results of the groundwater/soil gas supplemental LFI for the 100-FR-3 Operable Unit. The primary objective of this investigation was to assess the lateral distribution of TCE in shallow (3 to 5 ft below the water table) groundwater associated with the 100-FR-3 Operable Unit. The second objective was to assess soil gas (3 to 5 concentrations in the study area in an attempt to identify potential sources of TCE and develop a correlation between soil gas and groundwater concentrations). Finally, the third objective of the investigation was to refine the site conceptual model

Drip Irrigation Aided Phytoremediation for Removal of TCE FR-om Groundwater

International Nuclear Information System (INIS)

Wilde, E.W.

2003-01-01

Groundwater in D-Area at the Savannah River Site (SRS) is contaminated with trichloroethylene (TCE) and by-products resulting FR-om discharges of this organic solvent during past disposal practices. This contaminated groundwater occurs primarily at depths of 9 meters to 15 meters below ground surface, well below the depths that are typically penetrated by plant roots. The process investigated in this study involved pumping water FR-om the contaminated aquifer and discharging the water into overlying test plots two inches below the surface using drip irrigation. The field treatability study was conducted FR-om 8/31/00 to 4/18/02 using six 0.08 hectare test plots, two each containing pines, cottonwoods, and no vegetation (controls). The primary objective was to determine the overall effectiveness of the process for TCE removal and to determine the principal biotic and abiotic pathways for its removal. Results demonstrated that the process provides a viable method to remove TCE-contaminated groundwater. The data clearly showed that the presence of trees reduced volatilization of TCE FR-om the drip irrigation system to the atmosphere. Influent groundwater TCE concentrations averaging 89 mg/L were reduced to non-detectable levels (less than 5 mg/L) within the upper two feet of soil (rhizosphere)

Modified gravity is one of the potential candidates to explain the accelerated expansion of the universe. Current study highlights the materialization of anisotropic compact stars in the context of f(R, G) theory of gravity. In particular, to gain insight in the physical behavior of three stars namely, Her X1, SAX J 1808-3658 and 4U 1820-30, energy density, and radial and tangential pressures are calculated. The f(R, G) gravity model is split into a Starobinsky like f(R) model and a power law f(G) model. The main feature of the work is a 3-dimensional graphical analysis in which, anisotropic measurements, energy conditions and stability attributes of these stars are discussed. It is shown that all three stars behave as usual for positive values of the f(G) model parameter n. (orig.)

Keys to evaluating and comparing FR fabric

Enright, M. [Westex Inc., Chicago, IL (United States)

Exposure to electric arc flashes can result in the ignition of clothing, and can kill people at distances of 10 feet. This article discussed recent standards and regulations passed to ensure that employees working on or near energized electrical equipment use protective clothing made of flame resistant (FR) fabrics. The codes will require companies to comply with CSA Standard Z462 and determine which protective garments and FR fabrics are available. Employers will also be required to perform flash hazard analyses in order to determine the potential energy of hazards. Flash hazard analyses are typically performed by calculating the potential incident energy of equipment. Protective clothing is required to meet corresponding hazard risk categories. The ASTM F1506 Standard was developed to provide minimum specifications for protective clothing. The standard requires that the fabric used in protective garments must be resistant to arc flashes of varying energy levels. Many companies are simplifying compliance to the standards by implementing uniform programs that meet the highest requirements of the Standards. Arc flash suits are then made available for tasks involving higher energy level equipment. It was concluded that it is important to identify potential hazards and obtain industry consensus standards before investing in FR protective clothing. 2 figs.

1977-01-01

Absolute and relative cross sections were obtained for the Penning-ionization (PI) reaction Ar*+Na→Ar+Na + +e and the associative-ionization (AI) reaction Ar*+Na→ArNa + +e. The studies were made by a merging-beams technique for a relative kinetic energy W of the reactants from nominally 0.01 to 10 eV for PI and 0.01 to 0.4 eV for AI. The Ar* represents a composite of Ar(4s 3 P 2 ) and Ar(4s 3 P 0 ). The PI is directed and occurs predominantly when the difference between the relative kinetic energy of the heavy products and the reactants is approximately 0.1 eV. Cross sections for AI are roughly proportional to W -1 . Cross sections for total ionization (AI plus PI) vary as W -1 / 3 for the lower W

An apparatus for the investigation of the Penning ionization using ionization processes of long lived metastable rare gas atoms is described. Methods of determining interaction energies and ionization rates from the measured energy spectra of the originating electrons are described and illustrated by several examples. Typical associative ionization processes are listed and the ionization rates are compared with those of the Penning ionization. Interactions with short-lived excited particles and the transfer of excitation without ionization are discussed. (J.U.)

The interaction between VRN - A1 and FR - A2 largely affect the frost tolerance of hexaploid wheat. Frost tolerance is critical for wheat survival during cold winters. Natural variation for this trait is mainly associated with allelic differences at the VERNALIZATION 1 (VRN1) and FROST RESISTANCE 2 (FR2) loci. VRN1 regulates the transition between vegetative and reproductive stages and FR2, a locus including several tandemly duplicated C-REPEAT BINDING FACTOR (CBF) transcription factors, regulates the expression of Cold-regulated genes. We identified sequence and copy number variation at these two loci among winter and spring wheat varieties and characterized their association with frost tolerance. We identified two FR-A2 haplotypes-'FR-A2-S' and 'FR-A2-T'-distinguished by two insertion/deletions and ten single nucleotide polymorphisms within the CBF-A12 and CBF-A15 genes. Increased copy number of CBF-A14 was frequently associated with the FR-A2-T haplotype and with higher CBF14 transcript levels in response to cold. Factorial ANOVAs revealed significant interactions between VRN1 and FR-A2 for frost tolerance in both winter and spring panels suggesting a crosstalk between vernalization and cold acclimation pathways. The model including these two loci and their interaction explained 32.0 and 20.7 % of the variation in frost tolerance in the winter and spring panels, respectively. The interaction was validated in a winter wheat F 4:5 population segregating for both genes. Increased VRN-A1 copy number was associated with improved frost tolerance among varieties carrying the FR-A2-T allele but not among those carrying the FR-A2-S allele. These results suggest that selection of varieties carrying the FR-A2-T allele and three copies of the recessive vrn-A1 allele would be a good strategy to improve frost tolerance in wheat.

Atemanhaltephase von 15 s kann ein 3D kV-MV CBCT aufgenommen werden. Dies reduziert Bewegungsartefakte und erhoeht den Patientenkomfort. Im Hinblick auf die klinische Implementierung wurde die Positionierungsgenauigkeit untersucht und mit klinisch-etablierten Bildgebungstechniken verglichen. Ein inhomogenes Thoraxphantom mit 4 tumoraehnlichen Inlays wurde in 10 vordefinierten Positionen aufgenommen und auf ein Planungs-CT registriert. Die neue kV-MV CBCT Bildgebungstechnik (90 -Rotation) wurde mit einem klinisch etablierten kV-Chest CBCT (360 ) sowie mit einem nichtklinischen kV-CBCT und einem niedrigdosierten MV-CBCT (je 180 ) verglichen. Manuelle Registrierung, automatische Registrierung vom Hersteller und eine eigens entwickelte Methode der automatischen Registrierung auf Basis des MATLAB-Registrierungs-Toolkits wurden angewandt. Die hochpraezise Phantompositionierung mit optischem Tracking reduzierte den systematischen Fehler auf 0,05 mm. Die gemittelten stochastischen Positionierungsfehler waren 0,5 ± 0,3 mm in rechts-links, 0,4 ± 0,4 mm in anteroposterior und 0,0 ± 0,4 mm in kraniokaudaler Richtung fuer kV-MV CBCT mit manueller Registrierung (mit einem maximalen Fehler von 1,4 mm). Das klinische kV-Chest CBCT ergab einen mittleren Fehler von 0,2 mm (andere Modalitaeten: 0,4-0,8 mm). Die beiden automatischen Registrierungsverfahren zeigten aehnliche Ergebnisse. Die Vergleichsstudie der Positionierungsgenauigkeit zwischen neuen kV-MV-CBCTs und klinisch-etablierter Volumenbildgebung zeigte weiterhin eine Registrierungsgenauigkeit unter 1 mm. Durch Reduktion der Bildaufnahmezeit auf eine Atemanhaltephase ist die kV-MV CBCT eine ideale Technik in stereotaktischer ablativer Strahlentherapie z. B. der Lunge. (orig.)

Thermodynamic laws for generalized f(R) gravity with curvature-matter coupling

International Nuclear Information System (INIS)

Wu Yabo; Zhao Yueyue; Cai Ronggen; Lu Jianbo; Lu Junwang; Gao Xiaojing

2012-01-01

The first law and the generalized second law (GSL) of thermodynamics for the generalized f(R) gravity with curvature-matter coupling are studied in the spatially homogeneous, isotropic FRW universe. The research results show that the field equations of the generalized f(R) gravity with curvature-matter coupling can be cast to the form of the first law of thermodynamics with the so-called the entropy production terms dS ¯ and the GSL can be given by considering the FRW universe filled only with ordinary matter enclosed by the dynamical apparent horizon with the Hawking temperature. Furthermore, as a concrete example, by utilizing the GSL the constraints on the gravitational model with f 1 (R)=R+αR l and f 2 (R)=R m are also discussed. It is worth noting these results given by us are quite general and can degenerate to the ones in Einstein's general relativity and pure f(R) gravity with non-coupling and non-minimal coupling as special cases. Comparing with the case of Einstein's general relativity, the appearance of the entropy production term dS ¯ in the first law of thermodynamics demonstrates that the horizon thermodynamics is non-equilibrium one for generalized f(R) gravity with curvature-matter coupling, which is consistent with the arguments given in Akbar and Cai (2007) [13] and Eling et al. (2006) [18].

On Analytical Solutions of f(R) Modified Gravity Theories in FLRW Cosmologies

Science.gov (United States)

Domazet, Silvije; Radovanović, Voja; Simonović, Marko; Štefančić, Hrvoje

2013-02-01

A novel analytical method for f(R) modified theories without matter in Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetimes is introduced. The equation of motion for the scale factor in terms of cosmic time is reduced to the equation for the evolution of the Ricci scalar R with the Hubble parameter H. The solution of equation of motion for actions of the form of power law in Ricci scalar R is presented with a detailed elaboration of the action quadratic in R. The reverse use of the introduced method is exemplified in finding functional forms f(R), which leads to specified scale factor functions. The analytical solutions are corroborated by numerical calculations with excellent agreement. Possible further applications to the phases of inflationary expansion and late-time acceleration as well as f(R) theories with radiation are outlined.

In this study, input variables for chemical transport models were compared from different meteorological drivers each with other and with the measured friction velocities in one place. Friction velocities are used as a measure of the mechanical turbulence, but are made available neither by numerical weather models nor routinely available observations: so they must either recalculate or estimated. In this study, friction velocities (u{sup *}), which is measured for years by the DWD in Lindenberg near Berlin, averaged over 30 minutes and have been made available to FU Berlin, compared with modeled values. The considered models are firstly the diagnostic interpolation model TRAMPER, on the other the prognostic models of the DWD COSMO-EU and the EZMWF. The boundary layer relevant parameters from the NWM were recalculated from the involved groups, which has been made for the COSMO-EU the one from the FU Berlin, the other from IfT in Leipzig. The boundary layer variables in the EZMWF model, however, were determined by TNO Netherlands. The measurements have shown that u{sup *} in the forest twice as high as above the meadow.

Late time acceleration of the universe in f(R) gravity model

International Nuclear Information System (INIS)

Mukherjee, Ankan

2014-01-01

In this work, a new way to look at the nature of late time dynamics of the universe for f(R) gravity models using the contracted Bianchi Identity has been proposed. As the Einstein field equations contain derivatives of the curvature scalar R, the contracted Bianchi identity yields a second order nonlinear differential equation in H, the Hubble parameter. This equation is studied for two particular forms of f(R), and the late time behaviour of the model is discussed. (author)

Studying the highly bent spectra of FR II-type radio galaxies with the KDA EXT model

Science.gov (United States)

Kuligowska, Elżbieta

2018-04-01

Context. The Kaiser, Dennett-Thorpe & Alexander (KDA, 1997, MNRAS, 292, 723) EXT model, that is, the extension of the KDA model of Fanaroff & Riley (FR) II-type source evolution, is applied and confronted with the observational data for selected FR II-type radio sources with significantly aged radio spectra. Aim. A sample of FR II-type radio galaxies with radio spectra strongly bent at their highest frequencies is used for testing the usefulness of the KDA EXT model. Methods: The dynamical evolution of FR II-type sources predicted with the KDA EXT model is briefly presented and discussed. The results are then compared to the ones obtained with the classical KDA approach, assuming the source's continuous injection and self-similarity. Results: The results and corresponding diagrams obtained for the eight sample sources indicate that the KDA EXT model predicts the observed radio spectra significantly better than the best spectral fit provided by the original KDA model.

Development of FR fuel cycle in japan (1) development scope of fuel cycle technology

International Nuclear Information System (INIS)

Nakamura, H.; Funasaka, H.; Namekawa, T.

2008-01-01

A fast reactor (FR) cycle has a potential to realize a sustainable energy supply system that is harmonized with environment by fully recycling both uranium (U) and transuranium (TRU) elements. In Japan, a Feasibility Study on Commercialized FR Cycle Systems (FS) was launched in July 1999, and through two different study phases, a final report was presented in 2006. As a result of FS, a combined system of sodium-cooled FR with mixed-oxide (MOX) fuel, advanced aqueous reprocessing and simplified pelletizing fuel fabrication was considered to be most promising for commercialization. The advanced aqueous reprocessing system, which is called the New Extraction system for TRU recovery (NEXT), consists of a U crystallization process for the bulk of U recovery, a simplified solvent extraction process for residual U, plutonium (Pu) and neptunium (Np) without Pu partitioning and purification, and a process for recovering americium (Am) and curium (Cm) from the raffinate. The ratio of Pu/U concentration in the mother solution after crystallization is adequate for MOX fuel fabrication, and thus complicated powder mixing processes for adjusting Pu content in MOX fuel can be eliminated in the subsequent simplified fuel fabrication system. In this system, lubricant-mixing process can also be eliminated by adopting the advanced technology in which lubricant is coated on the inner surface of a die before fuel powder supply. Such a simplification could help us overcoming the difficulty to treat MA bearing fuel powders in a hot cell. Ministry of Education, Culture, Sports, Science and Technology (MEXT) reviewed these results of FS in 2006 and identified the most promising FR cycle concept proposed in the FS phase II study as a mainline choice for commercialization. According to such a governmental assessment, R and D activities of FR cycle systems were decided to be concentrated mainly to the innovative technology development for the mainline concept. The stage of R and D project was

Stellar configurations in f(R) theories of gravity

International Nuclear Information System (INIS)

Henttunen, K.; Multamaeki, T.; Vilja, I.

2008-01-01

We study stellar configurations and the space-time around them in metric f(R) theories of gravity. In particular, we focus on the polytropic model of the Sun in two specific cases: the f(R)=R-μ 4 /R model and a model with a stabilizing higher order term f(R)=R-μ 4 /R+βR 3 /(3μ 4 ). We show how the stellar configuration in the f(R) theory can, by appropriate initial conditions, be selected to be equal to that described by the Lane-Emden equation and how a simple scaling relation exists between the solutions. We also derive the correct solution analytically near the center of the star in f(R) theory. Previous analytical and numerical results are confirmed, indicating that the space-time around the Sun is incompatible with solar system constraints in the f(R)=R-μ 4 /R model. Numerical work shows that stellar configurations, with a regular metric at the center, lead to γ PPN ≅1/2 outside the star for both models, i.e., the Schwarzschild-de Sitter space-time is not the correct vacuum solution for such configurations. This shows that even when one fine-tunes the initial conditions inside a star such that the mass of the effective scalar in the equivalent scalar-tensor theory is large, γ PPN is still 1/2 outside the star. Conversely, by selecting the Schwarzschild-de Sitter metric as the outside solution, or equivalently setting the mass of the effective scalar to be large outside the star, we find that the stellar configuration is unchanged but the metric is irregular at the center. The possibility of constructing a f(R) theory compatible with the solar system experiments and possible new constraints arising from the radius-mass relation of stellar objects is discussed

IIn this paper, we determine regular black hole solutions using a very general f(R) theory, coupled to a nonlinear electromagnetic field given by a Lagrangian L{sub NED}. The functions f(R) and L{sub NED} are in principle left unspecified. Instead, the model is constructed through a choice of the mass function M(r) presented in the metric coefficients. Solutions which have a regular behaviour of the geometric invariants are found. These solutions have two horizons, the event horizon and the Cauchy horizon. All energy conditions are satisfied in the whole space-time, except the strong energy condition (SEC), which is violated near the Cauchy horizon.We present also a new theorem related to the energy conditions in f(R) gravity, re-obtaining the well-known conditions in the context of general relativity when the geometry of the solution is the same.

Aim: The implementation of diagnostic standards enhances quality assurance. The American College of Radiology's breast imaging-reporting and data system (BI-RADS{sup TM}) is intended to standardize terminology in the mammography report, the assessment of the findings, and the recommendation af action to be taken. The purpose of this study was to assess the value of the standardized system for clinically apparent male breast tumors. Do the special male anatomy and physiology limit the applicability of an evaluation system designed for female screening mammograms? Methods: 4 investigators with different degrees of experience retrospectively evaluated 160 male mammograms. Our study was based on the 36 cases which could be correlated to histopathological findings: gynecomastia in the majority of cases, but also 4 invasive ductal carcinoma, 1 leiomyosarcoma and 1 ductal carcinoma in situ. Results: Assessment of the mammograms by BI-RADS{sup TM} (3{sup rd} Edition 1998) correctly placed all cases of malignancy into categories 4 and 5 without respect to the investigators's level of experience. Conclusion: Therefore, we conclude that the BI-RADS{sup TM}-classification can successfully be used to classify male mammograms with a high positive predictive value for malignancy. Knowledge of gender-specific imaging characteristics increases the specificity at a constant high level of sensitivity. (orig.)

Cosmology of f(R) gravity in the metric variational approach

Science.gov (United States)

Li, Baojiu; Barrow, John D.

2007-04-01

We consider the cosmologies that arise in a subclass of f(R) gravity with f(R)=R+μ2n+2/(-R)n and n∈(-1,0) in the metric (as opposed to the Palatini) variational approach to deriving the gravitational field equations. The calculations of the isotropic and homogeneous cosmological models are undertaken in the Jordan frame and at both the background and the perturbation levels. For the former, we also discuss the connection to the Einstein frame in which the extra degree of freedom in the theory is associated with a scalar field sharing some of the properties of a “chameleon” field. For the latter, we derive the cosmological perturbation equations in general theories of f(R) gravity in covariant form and implement them numerically to calculate the cosmic microwave background (CMB) temperature and matter power spectra of the cosmological model. The CMB power is shown to reduce at low l’s, and the matter power spectrum is almost scale independent at small scales, thus having a similar shape to that in standard general relativity. These are in stark contrast with what was found in the Palatini f(R) gravity, where the CMB power is largely amplified at low l’s and the matter spectrum is strongly scale dependent at small scales. These features make the present model more adaptable than that arising from the Palatini f(R) field equations, and none of the data on background evolution, CMB power spectrum, or matter power spectrum currently rule it out.

Chameleon halo modeling in f(R) gravity

International Nuclear Information System (INIS)

Li Yin; Hu, Wayne

2011-01-01

We model the chameleon effect on cosmological statistics for the modified gravity f(R) model of cosmic acceleration. The chameleon effect, required to make the model compatible with local tests of gravity, reduces force enhancement as a function of the depth of the gravitational potential wells of collapsed structure and so is readily incorporated into a halo model by including parameters for the chameleon mass threshold and rapidity of transition. We show that the abundance of halos around the chameleon mass threshold is enhanced by both the merging from below and the lack of merging to larger masses. This property also controls the power spectrum in the nonlinear regime and we provide a description of the transition to the linear regime that is valid for a wide range of f(R) models.

Wormholes in viable f(R) modified theories of gravity and weak energy condition

Energy Technology Data Exchange (ETDEWEB)

Pavlovic, Petar [Universitaet Hamburg, II. Institut fuer Theoretische Physik, Hamburg (Germany); Sossich, Marko [University of Zagreb, Department of Physics, Faculty of Electrical Engineering and Computing, Zagreb (Croatia)

2015-03-01

In this work wormholes in viable f(R) gravity models are analyzed. We are interested in exact solutions for stress-energy tensor components depending on different shape and redshift functions. Several solutions of gravitational equations for different f(R) models are examined. The solutions found imply no need for exotic material, while this need is implied in the standard general theory of relativity. A simple expression for weak energy condition (WEC) violation near the throat is derived and analyzed. High curvature regime is also discussed, as well as the question of the highest possible values of the Ricci scalar for which the WEC is not violated near the throat, and corresponding functions are calculated for several models. The approach here differs from the one that has been common since no additional assumptions to simplify the equations have been made, and the functions in f(R) models are not considered to be arbitrary functions, but rather a feature of the theory that has to be evaluated on the basis of consistency with observations for the Solar System and cosmological evolution. Therefore in this work we show that the existence of wormholes without exotic matter is not only possible in simple arbitrary f(R) models, but also in models that are in accordance with empirical data.

Models of f(R) cosmic acceleration that evade solar system tests

International Nuclear Information System (INIS)

Hu, Wayne; Sawicki, Ignacy

2007-01-01

We study a class of metric-variation f(R) models that accelerates the expansion without a cosmological constant and satisfies both cosmological and solar-system tests in the small-field limit of the parameter space. Solar-system tests alone place only weak bounds on these models, since the additional scalar degree of freedom is locked to the high-curvature general-relativistic prediction across more than 25 orders of magnitude in density, out through the solar corona. This agreement requires that the galactic halo be of sufficient extent to maintain the galaxy at high curvature in the presence of the low-curvature cosmological background. If the galactic halo and local environment in f(R) models do not have substantially deeper potentials than expected in ΛCDM, then cosmological field amplitudes |f R | > or approx.10 -6 will cause the galactic interior to evolve to low curvature during the acceleration epoch. Viability of large-deviation models therefore rests on the structure and evolution of the galactic halo, requiring cosmological simulations of f(R) models, and not directly on solar-system tests. Even small deviations that conservatively satisfy both galactic and solar-system constraints can still be tested by future, percent-level measurements of the linear power spectrum, while they remain undetectable to cosmological-distance measures. Although we illustrate these effects in a specific class of models, the requirements on f(R) are phrased in a nearly model-independent manner

During the XVIII and XIXth centuries, the fungal material was used as haemostatic dressing and bandage to keep the temperature and compress parts of the body. It was also used as cautery for moxibustion and was reported in several traditional pharmacopoeias (Hungarian, Chinese, Indian).

Brane f(R) gravity and the dark side of the universe

International Nuclear Information System (INIS)

Borzou, A.; Sepangi, H. R.; Shahidi, S.; Yousefi, R.

2009-01-01

We consider a brane world scenario in which the bulk action is assumed to have the form of a generic function of the Ricci scalar f(R) and derive the resulting Einstein field equation on the brane. In a constant curvature bulk a conserved geometric quantity appears in the field equations which can be associated with matter. We present spherically symmetric solutions which account for galaxy rotation curves in a specific form. Then cosmological solutions by assuming a specific form for f(R) are derived which can explain an accelerated expanding universe.

Dilated cardiomyopathy (DCM) is the most common type of cardiomyopathy with a prevalence of 1 out of 2,500 in adults. Due to mild clinical symptoms in the early phase of the disease, the true prevalence is probably even much higher. Patients present with variable clinical symptoms ranging from mild systolic impairment of left ventricular function to congestive heart failure. Even sudden cardiac death may be the first clinical symptom of DCM. The severity of the disease is defined by the degree of impairment of global left ventricular function. Arrhythmias, such as ventricular or supraventricular tachycardia, atrioventricular (AV) block, ventricular extrasystole and atrial fibrillation are common cardiac manifestations of DCM. Magnetic resonance imaging (MRI) plays an important role in the exact quantification of functional impairment of both ventricles and in the evaluation of regional wall motion abnormalities. With its excellent ability for the assessment of myocardial structure, it is becoming increasingly more important for risk stratification and therapy guidance. (orig.) [German] Die dilatative Kardiomyopathie (DCM) ist die haeufigste Form der Kardiomyopathie mit einer Praevalenz von 1/2500 Erwachsenen. Aufgrund der zunaechst milden klinischen Symptomatik ist jedoch von einer relativ hohen Dunkelziffer auszugehen. Die klinische Praesentation ist variabel, die Schwere der Erkrankung wird vom Ausmass der systolischen Funktionseinschraenkung bestimmt. Herzrhythmusstoerungen, wie ventrikulaere oder supraventrikulaere Tachykardien, AV-Blockierungen, ventrikulaere Extrasystolen und Vorhofflimmern sind moegliche klinische Manifestationen. Bei manchen Patienten ist der ploetzliche Herztod die erste klinische Manifestation der Erkrankung. Die kardiale MRT spielt eine bedeutende Rolle fuer die Beurteilung des Ausmasses der ventrikulaeren Dilatation, Dysfunktion und fuer die Beurteilung regionaler Wandbewegungsstoerungen.

Exploring the liminality: properties of haloes and subhaloes in borderline f(R) gravity

Science.gov (United States)

Shi, Difu; Li, Baojiu; Han, Jiaxin; Gao, Liang; Hellwing, Wojciech A.

2015-09-01

We investigate the properties of dark matter haloes and subhaloes in an f(R) gravity model with |fR0| = 10-6, using a very-high-resolution N-body simulation. The model is a borderline between being cosmologically interesting and yet still consistent with current data. We find that the halo mass function in this model has a maximum 20 per cent enhancement compared with the Λ-cold-dark-matter (ΛCDM) predictions between z = 1 and 0. Because of the chameleon mechanism which screens the deviation from standard gravity in dense environments, haloes more massive than 1013 h-1 M⊙ in this f(R) model have very similar properties to haloes of similar mass in ΛCDM, while less massive haloes, such as that of the Milky Way, can have steeper inner density profiles and higher velocity dispersions due to their weaker screening. The halo concentration is remarkably enhanced for low-mass haloes in this model due to a deepening of the total gravitational potential. Contrary to the naive expectation, the halo formation time zf is later for low-mass haloes in this model, a consequence of these haloes growing faster than their counterparts in ΛCDM at late times and the definition of zf. Subhaloes, especially those less massive than 1011 h-1 M⊙, are substantially more abundant in this f(R) model for host haloes less massive than 1013 h-1 M⊙. We discuss the implications of these results for the Milky Way satellite abundance problem. Although the overall halo and subhalo properties in this borderline f(R) model are close to their ΛCDM predictions, our results suggest that studies of the Local Group and astrophysical systems, aided by high-resolution simulations, can be valuable for further tests of it.

OpenAIRE

Ewert, Ulf Christian

1998-01-01

Herrschaftsmythen können als spezifische Gestaltungselemente einer Organisationskultur interpretiert werden. Sie waren in den frühneuzeitlichen Systemen Mittel des politischen Zusammenwirkens, gerichtet auf Integration und Definition der jeweiligen Organisation. Gegenstand der Untersuchung sind neun frühneuzeitliche Mythen, darunter der Roi Soleil, Neues Israel und Wilhelm Tell. Hinterfragt wurden wahrgenommene Ähnlichkeiten zwischen den neun Mythen, deren integrative und revolutionäre Muster...

The simplest non-minimal matter-geometry coupling in the f(R, T) cosmology

f(R, T) gravity is an extended theory of gravity in which the gravitational action contains general terms of both the Ricci scalar R and the trace of the energy-momentum tensor T. In this way, f(R, T) models are capable of describing a non-minimal coupling between geometry (through terms in R) and matter (through terms in T). In this article we construct a cosmological model from the simplest non-minimal matter-geometry coupling within the f(R, T) gravity formalism, by means of an effective energy-momentum tensor, given by the sum of the usual matter energy-momentum tensor with a dark energy contribution, with the latter coming from the matter-geometry coupling terms. We apply the energy conditions to our solutions in order to obtain a range of values for the free parameters of the model which yield a healthy and well-behaved scenario. For some values of the free parameters which are submissive to the energy conditions application, it is possible to predict a transition from a decelerated period of the expansion of the universe to a period of acceleration (dark energy era). We also propose further applications of this particular case of the f(R, T) formalism in order to check its reliability in other fields, rather than cosmology. (orig.)

Study of some chaotic inflationary models in f(R) gravity

Science.gov (United States)

Sharif, M.; Nawazish, Iqra

2018-04-01

In this paper, we discuss an inflationary scenario via scalar field and fluid cosmology for an anisotropic homogeneous universe model in f(R) gravity. We consider an equation of state which corresponds to a quasi-de Sitter expansion and investigate the effect of the anisotropy parameter for different values of the deviation parameter. We evaluate potential models like linear, quadratic and quartic models which correspond to chaotic inflation. We construct the observational parameters for a power-law model of f(R) gravity and construct the graphical analysis of tensor-scalar ratio and spectral index which indicates the consistency of these parameters with Planck 2015 data.
