The Very Low Angle Detector (VLAD) bank has been installed on the VESUVIO spectrometer at the ISIS spallation neutron source. The new device allows for high-energy inelastic neutron scattering measurements, at energies above 1 eV, maintaining the wave vector transfer lower than 10Å-1. This opens a still unexplored region of the kinematical (q, ω) space, enabling new and challenging experimental investigations in condensed matter. This paper describes the main instrumental features of the VLAD device, including instrument design, detector response, and calibration procedure.

Strong demand exists for an experimental facility enabling new experimental investigations on condensed matter systems based on epithermal neutron scattering at high energy and low momentum transfers. This need will be met by the very low angle detector (VLAD) bank, to be installed on the VESUVIO spectrometer at the ISIS spallation neutron source. The equipment will operate in the scattering angular range 1°<2θ<5°. Scattering measurements from a polycrystalline ice sample using a VLAD prototype demonstrates the effectiveness of the detection technique adopted for the construction of the full detector array. The resulting density of states in ice is 9±2 atoms/cell, in agreement with previous measurements.

Wide-area registration in outdoor environments on mobile phones is a challenging task in mobile augmented reality fields. We present a sensor-aware large-scale outdoor augmented reality system for recognition and tracking on mobile phones. GPS and gravity information is used to improve the VLAD performance for recognition. A kind of sensor-aware VLAD algorithm, which is self-adaptive to different scale scenes, is utilized to recognize complex scenes. Considering vision-based registration algorithms are too fragile and tend to drift, data coming from inertial sensors and vision are fused together by an extended Kalman filter (EKF) to achieve considerable improvements in tracking stability and robustness. Experimental results show that our method greatly enhances the recognition rate and eliminates the tracking jitters. PMID:26690439

New perspectives for epithermal neutron spectroscopy are opened by the development of new detectors for inverse geometry time of flight spectrometers at pulsed neutron sources. One example is the Very Low Angle Detector (VLAD) bank planned to be delivered, within the next 4 years, within the eVERDI project, on the neutron spectrometer VESUVIO, at the ISIS pulsed neutron source (UK). VLAD will extend the (q,ω) kinematical region for neutron scattering to low wavefactor transfer (q -1 ) still keeping energy transfer >1 eV, thus allowing the investigations of new experimental studies in condensed matter systems. The technique being developed for detection of epithermal neutrons, within this low q and high-energy transfer region, is the Resonance Detection Technique. In this work, the state of the detector development will be presented with special focus on the results obtained with some prototype detectors, namely YAP scintillators and cadmium-zinc-telluride semiconductors

New perspectives for epithermal neutron spectroscopy are opened up by the recent developments of Resonance Detectors (RD) for inverse geometry time-of-flight spectrometers at pulsed neutron sources. The RD is based on the combination of an analyser foil used as neutron-to-gamma converter and a suitable photon detector. Here, we report on the state of the RD which is based on a YAP scintillator viewing a natural uranium analyser foil. The response of the YAP detector to the radiative capture γ emission from the uranium analyser foil has been characterized with a bi-parametric measurement of a reference Pb sample, which allowed simultaneous measurements of both neutron time-of-flight and γ pulse height (energy) spectra. The analysis of the γ pulse height and neutron time-of-flight spectra permitted to identify the signal and background components. These measurements showed that a significant improvement in the signal-to-background ratio can be achieved by setting a lower level discrimination on the photon energy at about 600keV. The first application of RD is the Very Low Angle Detector Bank (VLAD) which is planned to be installed in the next three years as an upgrade of the VESUVIO spectrometer, at the ISIS pulsed neutron source. VLAD will extend the (q,ω) kinematical to low wave vector transfers (q10A-1) coupled to high-energy transfers (-bar ω>1eV), which is still unexplored by neutron scattering experiments. The first measurements obtained on an ice sample with a VLAD prototype consisting of four RD units are presented here

2016-01-01

This volume contains lecture notes from the courses given by Vlad Bally and Rama Cont at the Barcelona Summer School on Stochastic Analysis (July 2012). The notes of the course by Vlad Bally, co-authored with Lucia Caramellino, develop integration by parts formulas in an abstract setting, extending Malliavin's work on abstract Wiener spaces. The results are applied to prove absolute continuity and regularity results of the density for a broad class of random processes. Rama Cont's notes provide an introduction to the Functional Itô Calculus, a non-anticipative functional calculus that extends the classical Itô calculus to path-dependent functionals of stochastic processes. This calculus leads to a new class of path-dependent partial differential equations, termed Functional Kolmogorov Equations, which arise in the study of martingales and forward-backward stochastic differential equations. This book will appeal to both young and senior researchers in probability and stochastic processes, as well as to pract...

During the flight of vehicles, their propulsion energy must overcome gravity, to ensure the displacement of air masses on vehicle trajectory, to cover both energy losses from the friction between a solid surface and the air and also the kinetic energy of reflected air masses due to the impact with the flying vehicle. The flight optimization by increasing speed and reducing fuel consumption has directed research in the aerodynamics field. The flying vehicles shapes obtained through studies in the wind tunnel provide the optimization of the impact with the air masses and the airflow along the vehicle. By energy balance studies for vehicles in flight, the author Ioan Rusu directed his research in reducing the energy lost at vehicle impact with air masses. In this respect as compared to classical solutions for building flight vehicles aerodynamic surfaces which reduce the impact and friction with air masses, Ioan Rusu has invented a device which he named free compression tube for rockets, registered with the State Office for Inventions and Trademarks of Romania, OSIM, deposit f 2011 0352. Mounted in front of flight vehicles it eliminates significantly the impact and friction of air masses with the vehicle solid. The air masses come into contact with the air inside the free compression tube and the air-solid friction is eliminated and replaced by air to air friction.

Les Turcs dans Ţiganiada de Ion Budai-Deleanu Turcs in Ţiganiada of Ion Budai-Deleanu

Directory of Open Access Journals (Sweden)

Silviu Petcu

2012-05-01

Full Text Available La Ţiganiada d’Ion Budai-Deleanu, un des pères de la langue roumaine moderne, est une épopée placée dans la Munténie du XVe siècle et structurée sur deux plans : d'une part, un plan comique créé par le pittoresque du campement des « Tsiganes », mobilisés pour combattre les Turcs par le prince Vlad l'Empaleur, surnommé Dracula, et, d'autre part, un plan héroïque constitué par les actions de ce prince et son armée. La promesse d’émancipation des Rroms esclaves, avec attribution d'un territoire, en échange de leur alliance au combat est une pure fiction et même un anachronisme pour le XVe siècle. Mais à travers cette idée, Budai-Deleanu se révèle visionnaire et partisan du mouvement d’abolition de l'esclavage des Rroms qui n'arrivera à ses fins que le 20 février 1856. En raison de son insoumission entêtée au sultan Mahomet II, son courage et ses capacités stratégiques, Vlad l'Empaleur devait rester dans l'histoire roumaine comme un patriote qui voulait protéger son pays contre l'expansion ottomane – même s'il est plus connu à l'étranger sous la caricature d'un vampire. La Ţiganiada doit être appréciée avant tout comme une allégorie où le plan de la fiction remplace souvent le plan réel. Mais l'auteur, chargé d’un idéal patriotique, nous présente aussi le plan réel avec ses particularités historiques et nationales. La lutte opiniâtre de la petite armée roumaine formée de paysans et de boyards permet de retarder l'avancée des Turcs vers l'Europe centrale. Elle laisse ainsi le temps nécessaire à l'Europe de se préparer et de livrer des batailles dans des périodes plus favorables, avec des armes plus puissantes et plus efficaces que celles des Turcs. L'image des Turcs y est en tous points conforme à leur réputation, largement répandue dans les Balkans. Cruauté, perfidie, corruption et absence de compassion les caractérisent d'un bout à l'autre de l'œuvre, l’auteur montre

The resonant detector and its application to epithermal neutron spectroscopy

New perspectives for epithermal neutron spectroscopy are being opened by the development of the resonant detector (RD) and its use on inverse geometry time of flight spectrometers at spallation sources. The RD was first proposed in the 1980s and was recently brought to a performance level exceeding conventional neutron-sensitive Li-glass scintillator detectors. It features a photon counter coupled to a neutron analyzer foil. Resonant neutron absorption in the foil results in the emission of prompt gamma rays that are detected in the photon counter. The dimensions of the RD set the spatial resolution that can be achieved, ranging from a fraction of a cm to several cm. It can thus be tailored to the construction of detector arrays of different geometry. The main results of the research on this kind of detector are reported leading to the present optimized RD design based on a combination of YAP scintillation photon counter and uranium or gold analyzer foils. This detector has already been selected for application in the upgrade of the VESUVIO spectrometer on ISIS. A special application is the Very Low Angle Detector (VLAD) bank, which will extend the kinematical region for neutron scattering to low momentum transfer ( -1 ) whilst still keeping energy transfer >1 eV, thus allowing new experimental studies in condensed matter systems. The first results of tests made with prototype VLAD detectors are presented, confirming the usefulness of the RD for measurements at scattering angles as low as 2-5 deg

Monitoring risk-adjusted outcomes in congenital heart surgery: does the appropriateness of a risk model change with time?

Risk adjustment of outcomes in pediatric congenital heart surgery is challenging due to the great diversity in diagnoses and procedures. We have previously shown that variable life-adjusted display (VLAD) charts provide an effective graphic display of risk-adjusted outcomes in this specialty. A question arises as to whether the risk model used remains appropriate over time. We used a recently developed graphic technique to evaluate the performance of an existing risk model among those patients at a single center during 2000 to 2003 originally used in model development. We then compared the distribution of predicted risk among these patients with that among patients in 2004 to 2006. Finally, we constructed a VLAD chart of risk-adjusted outcomes for the latter period. Among 1083 patients between April 2000 and March 2003, the risk model performed well at predicted risks above 3%, underestimated mortality at 2% to 3% predicted risk, and overestimated mortality below 2% predicted risk. There was little difference in the distribution of predicted risk among these patients and among 903 patients between June 2004 and October 2006. Outcomes for the more recent period were appreciably better than those expected according to the risk model. This finding cannot be explained by any apparent bias in the risk model combined with changes in case-mix. Risk models can, and hopefully do, become out of date. There is scope for complacency in the risk-adjusted audit if the risk model used is not regularly recalibrated to reflect changing standards and expectations.

Re-resection rates after breast-conserving surgery as a performance indicator: introduction of a case-mix model to allow comparison between Dutch hospitals.

Re-resection rate after breast-conserving surgery (BCS) has been introduced as an indicator of quality of surgical treatment in international literature. The present study aims to develop a case-mix model for re-resection rates and to evaluate its performance in comparing results between hospitals. Electronic records of eligible patients diagnosed with in-situ and invasive breast cancer in 2006 and 2007 were derived from 16 hospitals in the Rotterdam Cancer Registry (RCR) (n = 961). A model was built in which prognostic factors for re-resections after BCS were identified and expected re-resection rate could be assessed for hospitals based on their case mix. To illustrate the opportunities of monitoring re-resections over time, after risk adjustment for patient profile, a VLAD chart was drawn for patients in one hospital. In general three out of every ten women had re-surgery; in about 50% this meant an additive mastectomy. Independent prognostic factors of re-resection after multivariate analysis were histological type, sublocalisation, tumour size, lymph node involvement and multifocal disease. After correction for case mix, one hospital was performing significantly less re-resections compared to the reference hospital. On the other hand, two were performing significantly more re-resections than was expected based on their patient mix. Our population-based study confirms earlier reports that re-resection is frequently required after an initial breast-conserving operation. Case-mix models such as the one we constructed can be used to correct for variation between hospitals performances. VLAD charts are valuable tools to monitor quality of care within individual hospitals. Copyright © 2011 Elsevier Ltd. All rights reserved.

Photon detectors for epithermal neutron scattering at high-ω and low-q

2004-01-01

Inelastic epithermal neutron scattering at high energy (ℎω≥1 eV) and low wave vector (q≤10 A -1 ) transfers is the unique technique for the investigation of high-energy excitations in a variety of systems, ranging from magnetic materials to semiconductors. The key issue in order to make these measurements feasible on inverse geometry spectrometers, is to develop suitable detection systems for neutrons in the energy range 1-100 eV. The Resonance Detector Spectrometer configuration has to be considered as the most promising approach for electron Volt neutron spectroscopy. This configuration will be employed in the new low angle detector bank, VLAD, planned for VESUVIO spectrometer operating at ISIS source

The extended meanings of medical terms. Difficulties in the practice of translation

Directory of Open Access Journals (Sweden)

2015-10-01

Full Text Available Taking into account that the structure of a specialized field is never homogeneous, in order to interpret or translate a term, we should define and know its different possible "semantic manifestations" (Martin, 1972: 125. In order to facilitate understanding and to ensure translation accuracy, we analyze - from the perspective of an internal polysemy - the terms of the medical lexicon which constitute a specific and restrictive use of the common language lexicon. Through the study of a selection of terms extracted from a specialized dictionary (Dicţionar Medical, Rusu V. 2010, this communication illustrates the restrictions and the extensions of meaning in a double translation: the terms taken from the common language with a restrictive meaning in the specialized field; the terms belonging to related disciplines and various fields adopting a specific meaning in the medical area. All these directions of change of meaning are thus envisaged to facilitate the practice of translation which raises both general and specific difficulties.

New perspectives for epithermal neutron spectroscopy have been opened up as a result of the development of the Resonance Detector and its use on inverse geometry time-of-flight spectrometers at spallation sources. A special application of the Resonance Detector is the Very Low Angle Detector Bank (VLAD) for the VESUVIO spectrometer at ISIS, operating in the angular range 1∘500 meV, a regime so far inaccessible to experimental studies on condensed matter systems. The HINS measurements complement the Deep Inelastic Neutron Scattering (DINS) measurements performed on VESUVIO in the high wavevector q(20 Å-11 eV), where the short-time single-particle dynamics can be sampled. This paper will revise the main components of the resolution for HINS measurements of VESUVIO. Instrument performances and examples of applications for neutron scattering processes at high energy and at low wavevector transfer are discussed.

We report the detection via VLA-D observations of ammonia of a circumstellar high-density molecular gas structure toward the massive young star related to the object Cepheus A-HW 2, a firm candidate for the powering source of the high-velocity molecular outflow in the region. We suggest that the circumstellar molecular gas structure could be related to the circumstellar disk previously suggested from infrared, H2O, and OH maser observations. We consider as a plausible scenario that the double radio continuum source of HW 2 could represent the ionized inner part of the circumstellar disk, in the same way as proposed to explain the double radio source in L1551. The observed motions in the circumstellar molecular gas can be produced by bound motions (e.g., infall or rotation) around a central mass of about 10-20 solar masses (B0.5 V star or earlier).

New perspectives for epithermal neutron spectroscopy have been opened up as a result of the development of the Resonance Detector and its use on inverse geometry time-of-flight spectrometers at spallation sources. A special application of the Resonance Detector is the Very Low Angle Detector Bank (VLAD) for the VESUVIO spectrometer at ISIS, operating in the angular range 1 deg. -1 ) and high energy (unlimited) transfer -bar ω>500meV, a regime so far inaccessible to experimental studies on condensed matter systems. The HINS measurements complement the Deep Inelastic Neutron Scattering (DINS) measurements performed on VESUVIO in the high wavevector q(20A -1 -1 ) and high energy transfer (-bar ω>1eV), where the short-time single-particle dynamics can be sampled. This paper will revise the main components of the resolution for HINS measurements of VESUVIO. Instrument performances and examples of applications for neutron scattering processes at high energy and at low wavevector transfer are discussed

New perspectives for epithermal neutron spectroscopy have been opened up as a result of the development of the Resonance Detector and its use on inverse geometry time-of-flight spectrometers at spallation sources. A special application of the Resonance Detector is the Very Low Angle Detector Bank (VLAD) for the VESUVIO spectrometer at ISIS, operating in the angular range 1 deg. <2{theta}<5 deg. This equipment allows High-energy Inelastic Neutron Scattering (HINS) measurements to be performed in the (q,{omega}) kinematical region at low wavevector (q<10A{sup -1}) and high energy (unlimited) transfer -bar {omega}>500meV, a regime so far inaccessible to experimental studies on condensed matter systems. The HINS measurements complement the Deep Inelastic Neutron Scattering (DINS) measurements performed on VESUVIO in the high wavevector q(20A{sup -1}1eV), where the short-time single-particle dynamics can be sampled. This paper will revise the main components of the resolution for HINS measurements of VESUVIO. Instrument performances and examples of applications for neutron scattering processes at high energy and at low wavevector transfer are discussed.

Full Text Available Betonun basınç dayanımı, betonarme sistemin yapısal bütünlüğü açısından hayati önem taşımaktadır. Gerek inşaat aşamasında gerekse inşaat tamamlandıktan sonra, farklı yapı elemanlarındaki basınç dayanımlarının bilinmesi, kontrol ve değerlendirme yapılabilmesi açısından oldukça önemlidir. Standartların ve yönetmeliklerin değişimiyle kontrol ve değerlendirme için beton dayanımının tespiti daha da önem kazanmıştır.Yapıya az hasar verecek şekilde, beton dayanımının bulunması önemlidir. Geri sıçramalı çekiç ile beton dayanımı tespiti ekonomik, pratik ve hasarsız olması nedeniyle çok kullanışlı bir yöntemdir. Yapılan çalışmalarda, geri sıçramalı çekiç ile karot numunesinden bulunan beton dayanımı arasında tutarsızlıklar gözlenmiştir. Geri sıçramalı çekiç okumaları herhangi bir düzeltme faktör dikkate alınmadan kullanılmaktadır. Bu da geri sıçramalı çekicin kullanımını ve güvenirliğini azaltmaktadır.Bu çalışmada, fck=14, fck=20 ve fck=24 MPa dayanımlara sahip deney elemanlarında 0.013N0-0.2N0-0.3N0-0.4N0-0.5N0-0.6N0-0.7N0 yük düzeylerinde her dört yüzeyinden en az beşer adet geri sıçramalı çekiç okuması alınmış, standart sapma analizi yapılmıştır. Elde edilen dayanımların, eksenel yük düzeyi ile değişimi irdelenmiştir. Eksenel yük düzeyinin de ayrı bir sapma yarattığı tespit edilmiştir. Eksenel yük düzeyine göre,  geri sıçramalı çekiç verileri için rekrasyon doğrusu bulunmuştur. Geri sıçramalı çekiç ile beton dayanımın elde edilmesinde eksenel yük düzeyinin de bir düzeltme faktörü olarak dikkate alması gerektiği görülmüştür.Anahtar Kelimeler: Beton dayanımı tespiti, Geri sıçramalı çekiç, Eksenel yük düzeyi, Rekrasyon doğrusu

Full Text Available Ariana M Levin, Irene Rusu, Anton Orlin, Mrinali P Gupta, Peter Coombs, Donald J D’Amico, Szilárd Kiss Department of Ophthalmology, Weill Cornell Medical College, New York, NY, USA Purpose: The aim of this study is to report peripheral reperfusion of ischemic areas of the retina on ultra-widefield fluorescein angiography (UWFA following anti-vascular endothelial growth factor (VEGF intravitreal injections in patients treated for diabetic retinopathy. Methods: This study is a retrospective review of 16 eyes of 15 patients with diabetic retinopathy, who received anti-VEGF intravitreal injections and underwent pre- and postinjection UWFA. The main outcome measured was the presence of reperfusion in postinjection UWFA images in areas of the retina that demonstrated nonperfusion in preinjection images. Images were analyzed for reperfusion qualitatively and quantitatively by two graders. Results: Twelve of 16 eyes (75% or 11 of 15 patients (73.3% demonstrated reperfusion following anti-VEGF injection. On UWFA, reperfusion was detected both within the field of 7-standard field (7SF fluorescein angiography and in the periphery outside the 7SF. Four of 16 eyes or 4 of 15 patients did not demonstrate reperfusion, one of which had extensive scarring from prior panretinal photocoagulation. Conclusion: In patients with diabetic retinopathy, treatment with anti-VEGF agents can be associated with reperfusion of areas of nonperfusion, as demonstrated by UWFA.

Full Text Available Vlad Alexandrescu1, Gerard Hubermont21Department of Vascular Surgery, Princess Paola Hospital, Marche- en-Famenne, Belgium; 2Department of Diabetology, Princess Paola Hospital, Marche-en-Famenne and Sainte-Thérèse Hospital, Bastogne, BelgiumAbstract: The angiosome principle was first described by Jan Taylor in 1987 in the plastic reconstructive surgery field, providing useful information on the vascular anatomy of the human body. Specifically concerning foot and ankle pathology, it may help the clinician to select better vascular access and specific strategies for revascularization. This knowledge may be particularly beneficial when treating diabetic neuroischemic foot wounds associated with particularly aggressive atherosclerotic disease and a poor collateral circulation. The implementation of angiosome-based strategies in diabetic infragenicular vascular reconstruction may afford encouraging wound healing and limb preservation rates using both bypass and endovascular techniques. The minimal invasiveness of these novel strategies enables us to perform more specific and more distal tibial and/or foot arterial reconstructions, in one or multiple targeted vessels. This paper reviews the available literature on this revascularization strategy and focuses on the potential benefit of angiosome-guided primary angioplasty for diabetic ischemic foot ulcers.Keywords: critical limb ischemia, diabetic foot, limb salvage, angiosomes, angioplasty

One unique feature of vertebrate definitive hematopoiesis is the ontogenic switching of hematopoietic stem cells from one anatomical compartment or niche to another. In mice, hematopoietic stem cells are believed to originate in the aorta-gonad-mesonephros (AGM), subsequently migrate to the fetal liver (FL) and finally colonize the bone marrow (BM). Yet, the differentiation potential of hematopoietic stem cells within early niches such as the AGM and FL remains incompletely defined. Here, we present in vivo analysis to delineate the differentiation potential of definitive hematopoietic stem/progenitor cells (HSPCs) in the zebrafish AGM and FL analogies, namely the ventral wall of dorsal aorta (VDA) and the posterior blood island (PBI), respectively. Cell fate mapping and analysis of zebrafish runx1(w84x) and vlad tepes (vlt(m651)) mutants revealed that HSPCs in the PBI gave rise to both erythroid and myeloid lineages. However, we surprisingly found that HSPCs in the VDA were not quiescent but were uniquely adapted to generate myeloid but not erythroid lineage cells. We further showed that such distinct differentiation output of HSPCs was, at least in part, ascribed to the different micro-environments present in these two niches. Our results highlight the importance of niche in shaping the differentiation output of developing HSPCs.

Improved motion description for action classification

Full Text Available Even though the importance of explicitly integrating motion characteristics in video descriptions has been demonstrated by several recent papers on action classification, our current work concludes that adequately decomposing visual motion into dominant and residual motions, i.e.: camera and scene motion, significantly improves action recognition algorithms. This holds true both for the extraction of the space-time trajectories and for computation of descriptors.We designed a new motion descriptor – the DCS descriptor – that captures additional information on local motion patterns enhancing results based on differential motion scalar quantities, divergence, curl and shear features. Finally, applying the recent VLAD coding technique proposed in image retrieval provides a substantial improvement for action recognition. These findings are complementary to each other and they outperformed all previously reported results by a significant margin on three challenging datasets: Hollywood 2, HMDB51 and Olympic Sports as reported in (Jain et al. (2013. These results were further improved by (Oneata et al. (2013; Wang and Schmid (2013; Zhu et al. (2013 through the use of the Fisher vector encoding. We therefore also employ Fisher vector in this paper and we further enhance our approach by combining trajectories from both optical flow and compensated flow. We as well provide additional details of DCS descriptors, including visualization. For extending the evaluation, a novel dataset with 101 action classes, UCF101, was added.

«Un poema es una cosa que será». Visceralidad, metalenguaje y renovación de la ruptura en Juan Gelman

Renata Pontes

2018-01-01

Full Text Available Este artículo propone un acercamiento a la poética de Juan Gelman desde algunos ejes centrales de su escritura. Considerando la correlación entre visceralidad y metalenguaje sustentamos que sus textos, al poner en marcha la transformación de la lengua, renuevan la ruptura bajo la lógica dialéctica entre destrucción y composición creativa. Este procedimiento, así como la contradicción entre deseo y padecimiento poético y la autoconsciencia de sí mismo a través de la poesía, conecta su proyecto intelectual con las prácticas vanguardistas de Vicente Huidobro y Vladímir Maiakóvski a principios del siglo XX. Frente a la recurrente asociación crítica de Juan Gelman a una “poética del dolor”, nuestro objetivo es reforzar “una toma de partido por la materialidad estético-lingüística como elemento fundamental y emancipador de la palabra” (Milán desde la escritura del poeta argentino. Al mismo tiempo, en diálogo con la sociología del arte, la poesía de Gelman enfatiza que la imbricación entre vida y lenguaje no sólo estimula la circunstancia y condición de la palabra a través de lo político. Refuerza as correspondencias entre el discurso poético y las demás formas de vivencia asegurando que la percepción estética es, inmanentemente social, y que la realidad de la lengua también da lugar a nuevas concepciones de mundo.

We herein present a method of selective nanophotothermolisys of pancreatic cancer (PC using multiwalled carbon nanotubes (MWCNTs functionalized with human serum albumin (HSA. With the purpose of testing the therapeutic value of these nanobioconjugates, we have developed an ex-vivo experimental platform. Surgically resected specimens from patients with PC were preserved in a cold medium and kept alive via intra-arterial perfusion. Additionally, the HSA-MWCNTs have been intra-arterially administered in the greater pancreatic artery under ultrasound guidance. Confocal and transmission electron microscopy combined with immunohistochemical staining have confirmed the selective accumulation of HSA-MWCNTs inside the human PC tissue. The external laser irradiation of the specimen has significantly produced extensive necrosis of the malign tissue after the intra-arterial administration of HSA-MWCNTs, without any harmful effects on the surrounding healthy parenchyma. We have obtained a selective photothermal ablation of the malign tissue based on the selective internalization of MWCNTs with HSA cargo inside the pancreatic adenocarcinoma after the ex-vivo intra

assemblage structure within each geologic type. The fauna showed weak compositional zonation into 3 groups (headwaters, coastal plain, and nearshore). Nearly 20% of the fish species collected have migratory life cycles (including Joturus pichardi, Agonostomus monticola, and Gobiomorus dormitor) that use freshwater and marine habitats. Some of these species probably rely on a natural flow regime and longitudinal connectivity for reproduction and dispersal of young, and natural flow regime and longitudinal connectivity are important factors for maintenance of functional linkages between the uplands and the coast in the ridge-to-reef corridor where the Monkey River is located. Therefore, we suggest that the viability of migratory fish populations may be a good biological indicator of upland-to-estuary connectivity important both to fishes and coastal ecosystem function. We recommend follow-up studies to substantiate the relative strengths of relationships between community structure and abiotic factors in contrasting geologies and to examine potential bottom-up responses of stream biota to the higher nutrient levels that were observed in stream waters draining the Santa Rosa Group geologic type.

New aspects concerning geoelectrical tests on shallow landslides in Telega, Romania Raluca Maftei, Emil Rusu, Roxana Ciurean, Ovidiu Avram, Ionut Scutelnicu, Stefan Grigorescu, Andrei Grigorescu (1) (1) GIR, Bucharest, Romania The analysis of natural hazards involved by landslides requires the revealing of both depth and relief of the slipping surface, and also to show the extension of the dislocated material areas. A particular aspect in Romania is related to the frequent occurrence of salt. It is to be mentioned that Romania contains the largest salt resources/reserves throughout Europe. This potential of about three billion tons could supply salt for the whole world population for over four hundred years. Telega village, separated by Campina town through Doftana River, is situated at 5 km from it, in the west part of Prahova County. The village covers a medium altitude relief (550m), characterized by irregularities of ground, many valleys and swales crossed by streams. On the left bank of Telega valley, the landslides' effects have a large extension, in some places being catastrophic. Among these, the one called at "Butoi" area presents a huge interest according of their produced destructions and because of the influence on Telega Spa, main communal road etc. In the above-mentioned sector, the slope is badly affected over a 0.4 sqkm surface. The morphology presents many scars, sometimes with steeps, waves with variable amplitudes and counter slope aspects in which water accumulates as lakes and swamps, with transversal and longitudinal fissures with different lengths and depths. The slope is very steep, especially in crest area. Besides the covering deluvial, clayey, yellow-gray quaternary rocks, other rocks form the basement are moving, in the detachment area marly, gray-black, fine stratified, sandy rocks interbeded with soft, gray sandstones of Meotian age are affected. Also, the rocks of the "salt breccias horizon" of Badenian age are affected. Predominantly

The quantitative interpretation of the resistivity geoelectrical vertical tests, and the correlation with the geological structure identified 3 sliding surfaces, from which only the upper one (2-6m depth) was known before the stability works. There were localized the rainfall waters circulation and accumulation zones, areas with high sliding risk. Same results were obtained in sliding zones, been localized the principal elements of the landslides, with practical implications in land instability and estimation of the evolution of the destructive phenomena mechanisms. With this study we try to quantify the complex relationship between the natural factors that generate the terrain instability phenomena and the intensity of the socio-economic effects, at a regional and local scale, by correlating the engineering geology information and geophysical data. Recent seismic research program (September 2009) conceived for "La Butoi" landslide, Telega locality, aims to a specific monitoring of the dynamic deformations, more active in the central part of the landslide, with reference to the shallow seismic refraction information obtained in the 2004 - 2005 period. The investigations were performed on a seismic lines network, and two seismic boundaries, in the shallow seismic section, were exhibited. As a result, one can observe the curvature tendency of the first arrivals sin-phase for the end-off shot devices, setting off the velocity increasing regime with depth; relative high variations and irregularities of

Energy indices in irrigated wheat production under conservation and conventional tillage and planting methods

Full Text Available Introduction: Conservation tillage system was recommended for soil erosion control in North America for the first time 60 years ago (Wang et al., 2006. Using this tillage system including minimum and zero tillage has been rapidly developed in recent years. Thearea covered by zero tillage in 2006 was 95 million ha all over the world (Dumanski et al., 2006. In addition to saving soil and water resources, conservation tillage system reduces energy consumption and improves energy indices by combining different tillage and planting operations. Results of research conducted in Fars province shows that conservation tillage saves fuel consumption for 77% compared to the conventional system (Afzalinia et al., 2009. Conservation tillage also reduces energy consumption from 23.6 to 42.8% in comparison to the conventional tillage (Rusu, 2005. Since energy indices would be affected by reduced input energies in conservation tillage, this research was conducted to evaluate the effect of different tillage and planting methods on energy inputs and energy indices in irrigated wheat production in Eghlid region. Materials and Methods: This research was performed to evaluate and compare the energy indices in irrigated wheat production under different tillage and planting methods. The study was conducted in the form of a randomized complete block experimental design with five treatments and three replications in Eghlid region. The treatments were included, conventional tillage and seed broadcasting (A, conventional tillage and planting with Machine Barzegar grain drill (B, reduced tillage and seeding with Roto-seeder (C, direct seeding with Jairan Sanaat grain drill (D, and direct seeding with Sfoggia direct drill (E. Experimental plots with 10 by 50 m dimensions were used in this study. Loss crop residues were taken out of the experimental plots and standing crop residues were retained in the plots. In the conventional tillage method, primary tillage was performed

Since evaluating and diminishing land degradation process due to landslides ( took as in its extensive meaning) demand data regarding physical and geological characteristics of the lithologic complexes implied, the project has as a main objective to increase the possibility for the principal geophysical methods of shallow land layers' resolute investigation ( seismometry, electrometry). In Romania, in 2001, law 575 was adopted: ‘‘Law regarding the approval of the Plan for the national territory fitting out- Section V- Natural risk areas''. It mentions that a Romania "Landslides Risk Map" should be edited. In these circumstances, in order to establish the potential and the probability for an area to be affected by soil instability phenomenon ( caused by natural or antropical factors), according to the COM 232/2006, Chapter 2, Section 1, Article 6, the first step that has to be made is to identify and classify risk areas from the studied region. The region will than be verified every 10 years and the measure taking program will than be made public and revised every 5 years. Areas affected by landslides can loose the following functions ( COM 232/2006, chapter 1, article 1): Soil functions Bio-mass production Accumulation, filtering and transforming Biodiversity Physical and cultural environment Raw materials Carbon

This study focuses upon the 1999 earthquake, which brought about the death of thousands of people, created crisis in the economy of both people and country, and eventually resulted in a sense of chaos. Secondly, the study also examines the relationship between the earthquake and education. In the research, this fragile structure has been investigated, and a special attention has been given to uniqueness. Le Chaos, le Désordre et les Relations Educationnelles Résumé L’un des objectifs de cette étude est de discuter si le concept de chaos mérite d’être un sujet de peur. Dans cette étude, sur la base du tremblement de terre qui a eu lieu en 1999 en Turquie, qui a provoqué des milliers de morts et qui a entraîné le chaos économique, nous avons essayé d’expliquer les concepts de chaos et de désordre et d’analyser la relation entre l’éducation, le chaos et le désordre apparus après le tremblement de terre. En réalisant cela, nous avons analysé cette structure fragile et plus précisément la structure fractale et avons souligné la singularité et le fait d’être dissemblable. En effet, l’auteur ne savait pas qu’il avait une proximité entre l’ordre et

In magnetic fusion plasmas, a significant fraction of the kinetic pressure is contributed by superthermal charged particles produced by auxiliary heating (fast ions and electrons) and fusion reactions (a-particles). Since these energetic particles are often far away from thermal equilibrium due to their non-Maxwellian distribution and steep pressure gradients, the free energy can excite electromagnetic instabilities to intensity levels well above the thermal fluctuations. The resultant electromagnetic turbulence could induce large transport of energetic particles, which could reduce heating efficiency, degrade overall plasma confinement, and damage fusion devices. Therefore, understanding and predicting energetic particle confinement properties are critical to the success of burning plasma experiments such as ITER since the ignition relies on plasma self-heating by a-particles. To promote international exchanges and collaborations on energetic particle physics, the biannual conference series under the auspices of the International Atomic Energy Agency (IAEA) were help in Kyiv (1989), Aspenas (1991), Trieste (1993), Princeton (1995), JET/Abingdon (1997), Naka (1999), Gothenburg (2001), San Diego (2003), Takayama (2005), Kloster Seeon (2007), Kyiv (2009), and Austin (2011). The papers in this special section were presented at the most recent meeting, the 13th IAEA Technical Meeting on Energetic Particles in Magnetic Confinement Systems, which was hosted by the Fusion Simulation Center, Peking University, Beijing, China (17-20 September 2013). The program of the meeting consisted of 71 presentations, including 13 invited talks, 26 oral contributed talks, 30 posters, and 2 summary talks, which were selected by the International Advisory Committee (IAC). The IAC members include H. Berk, L.G. Eriksson, A. Fasoli, W. Heidbrink, Ya. Kolesnichenko, Ph. Lauber, Z. Lin, R. Nazikian, S. Pinches, S. Sharapov, K. Shinohara, K. Toi, G. Vlad, and X.T. Ding.

Full Text Available Sevgili meslektaşlarım, Ülkemizde Adli Tıp Uzmanları sayısının otuza yaklaştığının sevinçle dile getirildiği bir toplantıda üç yıllık Adli Tıp Uzmanı olduğum yıllardan günümüze çok uzun süre geçmedi gibi geliyor bana. Bu sürede alanımız hem nitelik olarak hem de nicelik açısından çok yol aldı. Bu yolda ortaya çıkan ürünlerin bazılarında emek vermiş olmam beni hem heyecanlandırıyor, hem de onurlandırıyor doğrusu. Adli Tıp Uzmanları Derneği'nin kuruluşunun alanımızın kimliğine yeni bir yapı kazandırdığı kanısındayım. Varlığımızı, var sayılışımızı bu dernek çatısı altında birlikte paylaşıyoruz. Süren etkinlikleri ile birlikte gelişme ve üretme evreleri yaşıyoruz. Sizlerle bir zaman diliminin öyküsünü dilim dön- düğünce, tanık olduğum kadarı ile paylaşmak istiyorum. Bu kısa öykü elinizdeki bu derginin günümüze gelinceye kadar geçirdiği evrelerin yazılı olmayan bölümüdür. Yazılı olanlara bakıp da geçirdiği evreleri azımsamayalım diye. Derneğimizin katıldığı ilk etkinliklerinden birinde İTÜ toplantı salonlarında oturum aralarında, çok önceleri sıkça dile getirilen bir konu daha heyecanla tartışılmaya başlandı. Bu, derneğin bir yayın organı olması isteği idi. O güne kadar şimdilerde çıkmayan bir iletişim aracımız vardı. Bir sayfa kağıdın katlandığı, ne emeklerle iletişim ağım oluşturmaya çalışan. İMHOTEP. Bu, şimdiki, nasıl bir yayın organı olmalıydı? Hedeflerini tanışıp belirlemeliydik. Hatta heyecanla acaba adı ne olmalıydı? İçeriği, sayfaları, Hayır! Hayır!!! Kapak daha önemliydi? Kapağın biçimi ve rengi uzun yıllar sonra özelliğini böyle koruyabilir miydi? Sayfaları oluşturacak kağıt, basım özellikleri yıllar sonra bakıldığında dolgun ve iyi görünmeliydi...Bunlar ve benzeri bir dizi hoş ve şirin tartışmalar sonunda bir toplantı günü ve g

Kongre İzlenimleri

yapılacağı tartışılıp karar verilecekti. Daha doğrusu bu tartışmadan ziyade ciddi bir yarıştı. Bu aşamada Türkiye’den kongreye katılan tüm arkadaşlar böyle bir kongreye ev sahipliği yapabileceğimiz, bunun ülkemizdeki adli tıp ve adli bilimlerin gelişimine katkısı olacağı, ülkemizin en üst düzeyde tanıtımına destek olacağı inancına sahiptik. Aslında demek olarak bir uluslar arası kongreye ev sahipliği yapmamızın; önemli bir zorunluluk olduğu, en az 10 yıldır gündemde idi. Başta Prof Dr Serpil Salaçin olmak üzere, hocalarımız da bizleri teşvik etmek için sürekli uyarıda bulunuyorlardı. Bu nedenle 2004 İstanbul kongresinden başlayarak; Gaziantep’e kadar giderek artan sayıda yabancı konukla ve giderek artan bir ivme ile ciddi deneyim kazanıldı. Kocaeli’ndeki kongrenin de yabancı ortaklı yapılması ve uluslararası kongre için ön deneyim olması kararlaştırıldı. Bu nedenle, Porto’ya giderken bu kongreyi ülkemize getirmeye aday olmak açısından, ruhen ve fiziksel olarak hazırdık. ATUD Meslekte Yeterlilik Kurulu’nun 4 üyesi ile ATUD başkan yardımcısı da kongrede hazırdı. Tüm ATUD üyeleri ve Adli Bilimler camiasından meslektaşlarımız gibi, diğer ATUD Yönetim Kurulu ve Meslekte Yeterlilik Kurulu üyesi meslektaşlarımızın da kalplerinin bizimle olduğunu biliyorduk. Bu güçle, ülkemiz adına kongreye ev sahipliği yapmak için aday olduk. Diğer aday ülke de İspanya idi. Onlar Granada’yı, biz de Antalya’yı gösterdik. Bu aşamada, kongre başkanlığı önerimizi kabul eden, ATUD MYK Başkanı Prof Dr Mete Gülmen hoca’nın başkanlığında, katılan tüm Türk üyelerin olağan üstü bir çabası başladı (TÜRK TİMİ. Aday ülkeler arasında karar verecek ve bunları etkileyebilecek uluslararası üne sahip meslektaşlarımızla (örn; Prof. Anthony Busuttil, ECLM Başkanı Prof. Pekka Saukko, IALM Başkanı Prof. Nuno Vieira, MAFS Başkan Yard
