Delmas, C.

2010-07-15

This text was published in 1978 after the presentation of a disarmament plan to the United Nations assembly by the French president, Giscard d'Estaing. The author comments the differences and the evolutions of the notions of disarmament, arms control and arms limitations, and how these notions appeared or have been used in international conferences, conventions or treaties through history, with either moral or political backgrounds since the sixteenth century, until the situation of nuclear balance after the Second World War. Then appeared the arms control approach and its associated treaties. The author outlines the originality of the French new approach to disarmament according to the President's intervention

With 6 independent experiments of gamma irradiation on the three lily cultivars, cvs. Siberia, Le reve and Sorbonne, incidence and severity of lily leaf blight was investigated on leaves and petals at 8-d after infection. 200 Gy of gamma irradiation decreased at 13-25% of severity on the leaf of Sorbonne, but it increased at 2-5% of severity on the leaf of Siberia and Le reve. Chemical substitutes such as NSS and NaDCC were not effective to control of lily blight on cuttings. By 200 Gy of gamma irradiation treatment, chlorophyll contents were statistically significantly decreased at 12-d after irradiation and the longevities vaselife of fully open flower of Siberia and Sorbonne were increased at 0.4 to 1.2 days. In addition, the relative fresh weights of the gamma irradiated cuttings were severely dried compared to the non-irradiated control. On the other hands, the symptoms of phyto-toxicity of high dose gamma irradiation at 1 or 2 kGy on cv.

Transfer pricing and the Czech tax policy

Directory of Open Access Journals (Sweden)

Veronika Solilová

2010-01-01

Full Text Available The Czech Republic as a small open economy with an extensive network of the international tax treaties for the avoidance of the double taxation prevents from shifting the tax base of the associated enterprises to countries with preferential tax regime through transfer pricing rules. Transfer pricing as one of the important areas of international taxes determines how the profits of the multinational enterprises are split between the jurisdictions in which they operate and which countries get to tax those profits. This situation may affect the global budget of the multinational enterprises and the tax reve­nues of the jurisdictions. This paper is focused on the transfer pricing rules used in the Czech Republic and makes recommendations for the Czech tax policy in this area based on the analysis of the transfer pricing rules in the EU Member States.

Effects of toroidal coupling on the non-linear evolution of tearing modes and on the stochastisation of the magnetic field topology in plasmas

International Nuclear Information System (INIS)

Edery, D.; Pellat, R.; Soule, J.L.

1981-01-01

The resistive MHD equations have been handled in toroidal geometry following the tokamak ordering, in order to obtain a simplified set of non-linear equations. This system of equations is compact, closed, consistent and exact to the first two orders in the expansion in the inverse aspect ratio. Studies of the non-linear evolution of tearing modes in the real geometry of tokamak discharges are now in progress, and quite significant results have been obtained from the numerical code REVE of Fontenay based on our above model. From the analytical results, strong linear coupling between neighbouring modes is expected as is demonstrated by the numerical results in the linear, and non-linear regimes. Moreover, coupling exhibits a stochastic structure of the magnetic field lines, the threshold of which is seen to be easily computed by a simple analytical criterion. (orig.)

Increase in Mexican and Latin American scientific articles on irritable bowel syndrome.

Porras, R; López-Colombo, A; Schmulson, M

2015-01-01

There is an implied perception that little scientific information on irritable bowel syndrome (IBS) comes out of Mexico and Latin America in the international medical literature, but the number and tendencies of articles from the region on IBS are not known. To determine the number and type of Mexican and Latin American articles on IBS published between 1990-2015. A systematic search of Medline was carried out employing the terms « Irritable Bowel Syndrome » or its abbreviation (IBS). Mexico and every other Latin American country were added to specify the search. The articles were selected if they were published in Mexico and/or the rest of Latin America, if they were international papers on IBS in the region, or if they were written by Mexican and/or Latin American authors. In addition, the articles were classified into the following categories: Reviews/Editorials/Letters to the Editor (REV/ED), Epidemiology/Quality of Life/Psychosocial Factors (EPI/QOL), Diagnostic (DX), Treatment (TX), and Translational/Pathophysiologic (TRANS) studies. A total of 66 articles from Mexico and 47 from Latin America were identified, but only 87.7 and 48.9%, respectively, fit the selection criteria. Category distribution was: EPI/QOL: 36.2%, REV/ED: 27.5%, TRANS: 18.8, TX: 10%, and DX: 7.5% and was similar between Mexico and Latin America (p=0.33). The year 2005 saw an increase in the number of articles in Mexico, with a peak in 2010. The figures for Latin American articles remained stable over the years, with a peak in 2012. A noticeable increase has been observed over the last decade in the research conducted on IBS in Mexico and Latin America. Even though the EPI/QOL studies predominate, the sophistication of research is reflected in the TRANS studies that are in third place of frequency. The information referred to herein demonstrates maturity in the field, making it possible to carry out consensuses based on local data. Copyright © 2015 Asociación Mexicana de

In the present third volume methods for describing of the thermal interactions in multiphase dynamics are provided. In addition a large number of valuable experiments is collected and predicted using the methods introduced in this monograph. In this way the accuracy of the methods is reve...

On the use of blowup to study regularizations of singularities of piecewise smooth dynamical systems in R^3

DEFF Research Database (Denmark)

Kristiansen, Kristian Uldall; Hogan, S. J.

2015-01-01

In this paper we use the blowup method of Dumortier and Roussarie, in the formulation due to Krupa and Szmolyan, to study the regularization of singularities of piecewise smooth dynamical systems in R3. Using the regularization method of Sotomayor and Teixeira, we first demonstrate the power of our...... approach by considering the case of a fold line. We quickly extend a main result of Reves and Seara in a simple manner. Then, for the two-fold singularity, we show that the regularized system only fully retains the features of the singular canards in the piecewise smooth system in the cases when...... the sliding region does not include a full sector of singular canards. In particular, we show that every locally unique primary singular canard persists the regularizing perturbation. For the case of a sector of primary singular canards, we show that the regularized system contains a canard, provided...

Entropy of gravitating systems: scaling laws versus radial profiles

International Nuclear Information System (INIS)

Pesci, Alessandro

2007-01-01

Through the consideration of spherically symmetric gravitating systems consisting of perfect fluids with linear equation of state constrained to be in a finite volume, an account is given of the properties of entropy at conditions in which it is no longer an extensive quantity (it does not scale with the system's size). To accomplish this, the methods introduced by Oppenheim (2003 Phys. Rev.E 68 016108) to characterize non-extensivity are used, suitably generalized to the case of gravitating systems subject to an external pressure. In particular when, far from the system's Schwarzschild limit, both area scaling for conventional entropy and inverse radius law for the temperature set in (i.e. the same properties of the corresponding black hole thermodynamical quantities), the entropy profile is found to behave like 1/r, with r the area radius inside the system. In such circumstances entropy heavily resides in internal layers, in opposition to what happens when area scaling is gained while approaching the Schwarzschild mass, in which case conventional entropy lies at the surface of the system. The information content of these systems, even if it globally scales like the area, is then stored in the whole volume, instead of packed on the boundary

Full Text Available This paper considers two of the cultural values of g eoheritage: the mythological and the religious value, while introducing Omu peak and Ial omi ţ a cave, two natural destinations located within the Bucegi Mountains of Romania’s Southern Ca rpathians. Although mythology and religion share common aspects, it is necessary to d istinguish them. Mythology emerged in ancient times as a way of explaining the physical world, wher eas religion characterizes an upper stage in the evolution of mankind. Mythology is reduced to s piritual beliefs, while religion is based upon sacred practices to recall and strengthen these bel iefs. The religious value of geoheritage is conditioned by the existence of sacred relics or pl aces of worship close to geological formations. According to the age of these items, the religious value can be either pre-historical or historical. Omu peak has only acquired a mythological value sin ce hypotheses related to its religious value are not confirmed. Ialomi ţ a cave has acquired both a mythological and a relig ious value. In addition to their exploration as close components o f geoheritage, a brief model for their assessment is also introduced. Both steps aim to en courage landform exploitation not only by means of scientific interpretation but also by reve aling and explaining their cultural attributes.

REVE (REactor for Virtual Experiments) is an international project aimed at developing tools to simulate neutron irradiation effects in Light Water Reactor materials (Fe, Ni or Zr-based alloys). One of the important steps of the project is to characterise the displacement cascades induced by neutrons. Accordingly, the Department of Material Studies of Electricite de France developed an analytical model based on the binary collision approximation. This model, called INCAS (INtegration of CAScades), was devised to be applied on pure elements; however, it can also be used on diluted alloys (reactor pressure vessel steels, etc.) or alloys composed of atoms with close atomic numbers (stainless steels, etc.). INCAS describes displacement cascades by taking into account the nuclear collisions and electronic interactions undergone by the moving atoms. In particular, it enables to determine the mean number of sub-cascades induced by a PKA (depending on its energy) as well as the mean energy dissipated in each of them. The experimental validation of INCAS requires a large effort and could not be carried out in the framework of the study. However, it was verified that INCAS results are in conformity with those obtained from other approaches. As a first application, INCAS was applied to determine the sub-cascade spectrum induced in iron by the neutron spectrum corresponding to the central channel of the High Flux Irradiation Reactor of Oak Ridge National Laboratory.

Corpus linguistics allows researchers to process millions of words. However, the more words we analyse, i.e., the more data we acquire, the more urgent the call for correct data interpretation becomes. In recent years, a number of studies saw the light attempting to profile some prolific authors' linguistic decline, linking this decline to pathological conditions such as Alzheimer's Disease (AD). However, in line with the nature of the (literary) work that was analysed, numbers alone do not suffice to 'tell the story'. The one and only objective of using statistical methods for the analysis of research data is to tell a story--what happened, when, and how. In the present study we describe a computerised but individualised approach to linguistic analysis--we propose a unifying approach, with firm grounds in Information Theory, that, independently from the specific parameter being investigated, guarantees to produce a robust model of the temporal dynamics of an author's linguistic richness over his or her lifetime. We applied this methodology to six renowned authors with an active writing life of four decades or more: Iris Murdoch, Gerard Reve, Hugo Claus, Agatha Christie, P.D. James, and Harry Mulisch. The first three were diagnosed with probable Alzheimer Disease, confirmed post-mortem for Iris Murdoch; this same condition was hypothesized for Agatha Christie. Our analysis reveals different evolutive patterns of lexical richness, in turn plausibly correlated with the authors' different conditions. Copyright © 2013 Elsevier Ltd. All rights reserved.

The experimental study is aimed at achieving the effect of hepatic tumor and tumor-bearing lobar or segmental resection by using combined transcatheter hepatic arterial embolization and retrograde hepatic venous embolization (THAE-RHVE) in experimental study. THAE-RHVE was carried out in 8 mongrel dogs. Hepatic arterial embolization was performed by injecting lipiodol followed by gelatin sponge particles, following complete occlusion of the hepatic vein with balloon catheter. Retrograde hepatic venous embolization (RHVE) was then performed by injecting a mixture of absolute ethanol and meglumini diatrizoatis (MD) via the inflated balloon catheter. Ethanol and MD were combined with a ratio of 1:1. RHVE alone was performed in 4 dogs as control. The animals were followed up for 1∼8 weeks with liver function test, CT, gross and microscopic examinations. There was no technical failure or procedural complications. Transient elevation of AST and ALT levels was seen immediately in both groups after the procedure. Follow-up CT after 3 weeks showed dense lipiodol accumulation in the embolized lobe or segment and the corresponding portal branches in the THAE-RHVE animals. At 1 week after THAE-RHVE, complete coagulation necrosis was seen at histologic examination in the embolized lobe. The hepatic vein and portal branches of the embolized area had thickened walls and were filled with thrombus. At 2 weeks, granulomatous tissue and inflammatory cell infiltration surrounding the necrotic area could be seen. At 4∼8 weeks, marked atrophy of the embolized lobe was found, and the necrotic area was progressively reducing in size and being replaced by fibrosis. In the control group, incomplete segmental coagulated necrosis was seen and the necrosis area wa smaller than that of THAE-REVE. Hepatic lobectomy or segmentectomy can be achieved with THAE-RHVE. This new method is safe and easy, and may be useful in the treatment of HCC

This study compared the accuracy of cone beam computed tomography (CBCT) and medical-grade CT in the context of evaluating the diagnostic value and accuracy of fiducial marker localization for reference marker-based guided surgery systems. Cadaver mandibles with attached radiopaque gutta-percha markers, as well as glass balls and composite cylinders of known dimensions, were measured manually with a highly accurate digital caliper. The objects were then scanned using a medical-grade CT scanner (Philips Brilliance 64) and five different CBCT scanners (Sirona Galileos, Morita 3D Accuitomo 80, Vatech PaX-Reve3D, 3M Imtech Iluma, and Planmeca ProMax 3D). The data were then imported into commercially available software, and measurements were made of the scanned markers and objects. CT and CBCT measurements were compared to each other and to the caliper measurements. The difference between the CBCT measurements and the caliper measurements was larger than the difference between the CT measurements and the caliper measurements. Measurements of the cadaver mandible and the geometric reference markers were highly accurate with CT. The average absolute errors of the human mandible measurements were 0.03 mm for CT and 0.23 mm for CBCT. The measurement errors of the geometric objects based on CT ranged between 0.00 and 0.12 mm, compared to an error range between 0.00 and 2.17 mm with the CBCT scanners. CT provided the most accurate images in this study, closely followed by one CBCT of the five tested. Although there were differences in the distance measurements of the hard tissue of the human mandible between CT and CBCT, these differences may not be of clinical significance for most diagnostic purposes. The fiducial marker localization error caused by some CBCT scanners may be a problem for guided surgery systems.

RPV-1: A Virtual Test Reactor to simulate irradiation effects in light water reactor pressure vessel steels

International Nuclear Information System (INIS)

Jumel, Stephanie; Van-Duysen, Jean Claude

2005-01-01

Many key components in commercial nuclear reactors are subject to neutron irradiation which modifies their mechanical properties. So far, the prediction of the in-service behavior and the lifetime of these components has required irradiations in so-called 'Experimental Test Reactors'. This predominantly empirical approach can now be supplemented by the development of physically based computer tools to simulate irradiation effects numerically. The devising of such tools, also called Virtual Test Reactors (VTRs), started in the framework of the REVE Project (REactor for Virtual Experiments). This project is a joint effort among Europe, the United States and Japan aimed at building VTRs able to simulate irradiation effects in pressure vessel steels and internal structures of LWRs. The European team has already built a first VTR, called RPV-1, devised for pressure vessel steels. Its inputs and outputs are similar to those of experimental irradiation programs carried out to assess the in-service behavior of reactor pressure vessels. RPV-1 is made of five codes and two databases which are linked up so as to receive, treat and/or convey data. A user friendly Python interface eases the running of the simulations and the visualization of the results. RPV-1 is sensitive to its inputs (neutron spectrum, temperature, ...) and provides results in conformity with experimental ones. The iterative improvement of RPV-1 has been started by the comparison of simulation results with the database of the IVAR experimental program led by the University of California Santa Barbara. These first successes led 40 European organizations to start developing RPV-2, an advanced version of RPV-1, as well as INTERN-1, a VTR devised to simulate irradiation effects in stainless steels, in a large effort (the PERFECT project) supported by the European Commission in the framework of the 6th Framework Program

This article analyses customer’s level of participation in co-production of service. A client’s, known as a co-producer’s involvement is a pretty new conception of participation in creation of service where customers participate in projects, in direct, all-round and not only physical ways, together with professional representatives of service providers. A customer’s activity is becoming an important factor in order to achieve the results of effective creation of service, considering that client’s level while participating plays an essential role in the creation of service. To accomplish an empirical investigation, two quality methods were selected (observation and interview, which were performed in the company, which provides the services of furniture design. Theoretical literature analyses showed that there are three levels of customer’s participation: low, average and high, which usually appear in creation of co-productive service. Empirical investigation reve-aled that while co-producing services of furniture design customer’s level of participation can be: low, average, average high and high. This shows that “pure” level of participation in co-production of furniture design service appears rarely, while intermediate (“impure” level of participation can be observed more frequently. It is established that customer’s personality, temper, stress, lack of designer’s attention, preliminary decisions, and goods peculiarities determine causes of customer’s involvement/ devolvement. It is established that it is hard to elucidate and reveal customer’s needs, wishes and motives when the level of participation in co-production of furniture design service is low, and, as a result of that, a chance that the results of a service could not correspond to all customers expectations, rises.

Quando o tumor reveste uma grande area de mesotclio, a pleurodese não é tao eficaz.Eficácia - uma revisão da li teratura inglesa de I966 a 1994 constatou que u talco foi o agente mais eficaz de pleurodese, cum uma taxa de sucesso de 93%, comparada cum a da tetraciclina de 67 %, doxicicli na de 72% e bleomicina de 54%. Outras séries reve1aram uma taxa de sucesso do talco sempre superior a 91 %.Custo - o talco é pouco dispendioso e se apl icado em suspensao (“slutTy” por tubo de toracostomia ainda reduz mais os custos inerentes a uma toracoscopia 4uando se utiliza o talco em pó, aprescntando cstas duas tecnicas, taxas ue eticacia scmelhantes. Reacçãoes Adversas Minor e Major Agudas- a toracalgia e a febre são OS efcitos adversos mains frequcntes, frequcntes de todos os agentes de pleurudese.

articles d’humour et des contenus générés par les utilisateurs, tandis que les sujets politiques controversés génèrent plus de commentaires. Plusieurs explications sont proposées afin de comprendre ce relatif écart entre les représentations des journalistes et le comportement en ligne des lecteurs.Quais são as matérias mais lidas nos sites de notícia? Nas redações de inter- net, os jornalistas possuem acesso a softwares que lhes permitem detectar as preferências de seus leitores em tempo real. Ao se limitarem a esses dados, os webjornalistas frequentemente declaram que “sexo, escândalo e celebridades” são a melhor receita para atrair leitores e “cliques”. De modo inverso, eles afirmam que suas matérias sobre política, economia e internacional dão resultados medíocres em termos de tráfego na internet. Os jornalistas também estabelecem uma clara distinção entre os grupos de leitores, entre aqueles que “clicam”, “curtem” (no Facebook e “tuitam” (no Twitter, ou escrevem comentários sobre as matérias. A partir de uma dupla abordagem quantita- tiva e qualitativa, este artigo examina se as representações dos jornalistas sobre as suas audiências divergem em relação ao comportamento real dos leitores. Utilizando-se de uma base de dados composta por 13.159 matérias publicadas entre 2007 e 2012 em um site de notícias francês, a análise indica que as matérias sobre sexo, escândalos e celebridades de fato atraem mais leitores do que as matérias sobre cultura ou internacional. Todavia, as matérias que tratam de política, as matérias mais longas, e as contribuições geradas pelos próprios usuários também são populares. Além disso, as preferências dos leitores variam quando as mensurações levam em consideração o número de “cliques”, “curtidas”, “tuites” ou de comentários sobre as matérias.

ştirenler. Kendine göre oıtak düşünce ve yürek ürünü olan dergiyi asılsız ve haksız yorumlayanlar. Ama tüm zorlukların üstesinden gelindiğini düşünüyorum. Bu nedenle benim kişisel olarak baştan beri üstlenmeyi düşündüğüm görevimin tamamlandığını düşünüyorum. Aşağıda bir kaç gün önce derneğimiz başkanlığına gönderdiğim görevden affım ile ilgili mektubu bu derneğin üyeleri olarak sizlerin de öğrenmeye hakkınız olduğunu düşünerek sizlerle paylaşmak istiyorum. Adli Tıp Uzmanları Derneği Başkanlığına, Sayın Prof. Dr. Gürsel Çetin, 26.03.2001 Derneğimizin kuruluşundan bu yana meslektaşlarımızın özverileri ile üretilenlere katkıda bulunmak hepimiz için görev olarak algılanıp yerine getirilmeye çalışıldı. Bu etkinlikler içinde bu alanın bilimsel üretimlerini paylaşabileceği, danışmanlı olarak çalışabilecek bir derginin oluşturulması fikri de derneğimizin bir etkinliğinde sizin de bildiğiniz koşullarda ortaya atıldı. Benimsendi. Bu üretimin gerçekleştirilmesinde görev verilenlerden de biri de bendim. Çıkarılacak derginin editörlük görevini bana vermiştiniz. Bana duyulan güvene ve verilmiş olan bu göreve teşekkür ediyorum. Adli Tıp Bülteni, ismi ile eldeki sınırlı olanaklarla rengi, kapağı, amblemi, formatı ile bir grup özverili arkadaşımızla birlikte doğdu. (ISSN 1300-865X kaydını aldı. Ben bu görevi bir meslek misyonu olarak gerçekleştirmeye çalıştım. Ulusal ve uluslar arası danışma kurulunun oluşturulmasında edindiğim uluslararası ilişkileri devreye sokarak bu kurulların zenginleştirilmesine çalıştım. Birlikte çalıştığımız arkadaşlarımızın her birinin özverileri ile dergi yazım kuralları, gelen makalelerin kaydı, danışmanlara gönderilmesi, danışman ve yazar arasındaki yazışmaların gerçekleştirilmesi, her sayının içeriği ve makale dışı yazı düzenlemeleri, sîzlerin de yakından bildiği bir
