Erythropoietin (EPO) increases the number of circulating erythrocytes and thus muscle oxygenation. The availability of the recombinant protein (rEPO) has increased the risk of its illegal use in sports, its detection being a difficult challenge. Five different hematopoietic parameters were initially chosen as indirect markers of rEPO abuse: concentration of serum EPO, concentration of serum-soluble transferrin receptors (sTFr), hematocrit, percentage of reticulocytes, and percentage of macrocytes. New models considering only hemoglobin, serum EPO concentration, and percentage of reticulocytes are simpler and seem to be more sensitive when low doses of rEPO are used. A more direct method of urine analysis (isoelectrofocusing, double blotting, and chemiluminescent detection) based on the charge differences between rEPO and endogenous EPO, related to their carbohydrate composition, provides proof of rEPO use. Furthermore, this approach permits the detection of darbepoetin, a direct analogue of EPO also known as NESP ("new erythropoiesis stimulating protein"). Recently a protein conjugate, "synthetic erythropoiesis protein" (SEP), containing precision-length, monodisperse, negatively charged polymers instead of oligosaccharides has been synthesized. Finally, EPO-mimetics are molecules capable of acting as EPO in dimerizing the EPO receptor. Two kinds of EPO-mimetics have been described: peptides and nonpeptides. The enhancement of oxygen availability to muscles by rEPO, analogues, and mimetics constitutes one of the main challenges to doping control. Major steps have already been developed for detection ofrEPO and some analogues. In the near future, the transfection to an athlete's body of genes that code for erythropoietin might be an emerging doping issue, and sports authorities have incorporated "gene doping" among the prohibited practices.

The use of collateral has become one of the most widespread risk mitigation techniques. While it brings stabilizing effects to the individual lender we argue that it may exacerbate systemic risk through margin call activation. We show how a liquidity shock to the cash lender may propagate as a solvency shock via liquidity hoarding even if the cash lender remains solvent in all states of nature. Albeit a cost-effective response of the cash lender to a liquidity shock, liquidity hoarding may le...

The IQ•SPECT system, which is equipped with multifocal collimators ( SMART ZOOM) and uses ordered-subset conjugate gradient minimization as the reconstruction algorithm, reduces the acquisition time of myocardial perfusion imaging compared with conventional SPECT systems equipped with low-energy high-resolution collimators. We compared the IQ•SPECT system with a conventional SPECT system for estimating left ventricular ejection fraction (LVEF) in patients with a small heart (end-systolic volume IQ•SPECT. End-systolic volume, end-diastolic volume, and LVEF were calculated using quantitative gated SPECT (QGS) and cardioREPO software. We compared the LVEF from gated myocardial perfusion SPECT to that from echocardiographic measurements. Results: End-diastolic volume, end-systolic volume, and LVEF as obtained from conventional SPECT, IQ•SPECT, and echocardiography showed a good to excellent correlation regardless of whether they were calculated using QGS or using cardioREPO. Although LVEF calculated using QGS significantly differed between conventional SPECT and IQ•SPECT (65.4% ± 13.8% vs. 68.4% ± 15.2%) ( P = 0.0002), LVEF calculated using cardioREPO did not (69.5% ± 10.6% vs. 69.5% ± 11.0%). Likewise, although LVEF calculated using QGS significantly differed between conventional SPECT and IQ•SPECT (75.0 ± 9.6 vs. 79.5 ± 8.3) ( P = 0.0005), LVEF calculated using cardioREPO did not (72.3% ± 9.0% vs. 74.3% ± 8.3%). Conclusion: In small-heart patients, the difference in LVEF between IQ•SPECT and conventional SPECT was less when calculated using cardioREPO than when calculated using QGS. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

Leverage bubble

Science.gov (United States)

Yan, Wanfeng; Woodard, Ryan; Sornette, Didier

2012-01-01

Leverage is strongly related to liquidity in a market and lack of liquidity is considered a cause and/or consequence of the recent financial crisis. A repurchase agreement is a financial instrument where a security is sold simultaneously with an agreement to buy it back at a later date. Repurchase agreement (repo) market size is a very important element in calculating the overall leverage in a financial market. Therefore, studying the behavior of repo market size can help to understand a process that can contribute to the birth of a financial crisis. We hypothesize that herding behavior among large investors led to massive over-leveraging through the use of repos, resulting in a bubble (built up over the previous years) and subsequent crash in this market in early 2008. We use the Johansen-Ledoit-Sornette (JLS) model of rational expectation bubbles and behavioral finance to study the dynamics of the repo market that led to the crash. The JLS model qualifies a bubble by the presence of characteristic patterns in the price dynamics, called log-periodic power law (LPPL) behavior. We show that there was significant LPPL behavior in the market before that crash and that the predicted range of times predicted by the model for the end of the bubble is consistent with the observations.

Changes to the key monetary policy variables, the Repo and the Reverse Repo rates, are initially expected to be reflected in the OMO rates and the call money market rates, before being passedthrough to commercial bank retail interest rates. It is important to obtain a good understanding of the speed and magnitude of the interest rate pass-through to make timely monet...

2017-08-01

Full Text Available This paper examines the effect of monetary policy shocks on exchange rate in a Multiple Indicator Approach (MIA framework. This study has employed a monetary policy index of key monetary policy instruments in India (Bank rate, Cash Reserve Ratio, Repo and Reverse Repo rates. The study finds the empirical evidence for puzzling behavior of price level and exchange rate. Both price and exchange rate increase initially in response to a contractionary policy shock. Policy shocks affect output, inflation and exchange rate to an appreciable extent over a forecasting horizon of one year.

Kinetics of Roasting Decomposition of the Rare Earth Elements by CaO and Coal

2017-06-01

Full Text Available The roasting method of magnetic tailing mixed with CaO and coal was used to recycle the rare earth elements (REE in magnetic tailing. The phase transformation and decomposition process were researched during the roasting processes. The results showed that the decomposition processes of REE in magnetic tailing were divided into two steps. The first step from 380 to 431 °C mainly entailed the decomposition of bastnaesite (REFCO3. The second step from 605 to 716 °C mainly included the decomposition of monazite (REPO4. The decomposition products were primarily RE2O3, Ce0.75Nd0.25O1.875, CeO2, Ca5F(PO43, and CaF2. Adding CaO could reduce the decomposition temperature of REFCO3 and REPO4. Meanwhile, the decomposition effect of CaO on bastnaesite and monazite was significant. Besides, the effects of the roasting time, roasting temperature, and CaO addition level on the decomposition rate were studied. The optimum technological conditions were a roasting time of 60 min; roasting temperature of 750 °C; and CaO addition level of 20% (w/w. The maximum decomposition rate of REFCO3 and REPO4 was 99.87%. The roasting time and temperature were the major factors influencing the decomposition rate. The kinetics process of the decomposition of REFCO3 and REPO4 accorded with the interfacial reaction kinetics model. The reaction rate controlling steps were divided into two steps. The first step (at low temperature was controlled by a chemical reaction with an activation energy of 52.67 kJ/mol. The second step (at high temperature was controlled by diffusion with an activation energy of 8.5 kJ/mol.

Model calculations were performed with the EMOS/REPOS code describing the release of radionuclides from a salt formation, and radionuclide transport in the cap rock was computed separately for one-dimensional or multidimensional dispersion using the SWIFT code. The EMOS code, however, is basically designed so as to allow both the calculation of radionuclide release from a mine opening in a salt formation with the REPOS code, and the subsequent disperson processes in the cap rock and the resulting radiation exposure in the biosphere, with the help of several other modules. These modules have been developed and implemented. Furthermore, the EMOS code was provided with a Monte-Carlo frame, in order to take into account the range of variation of input data, referring to the mine opening, the cap rock, and the biosphere.

2009-03-01

Full Text Available Abstract Background The production of new neurons during adulthood and their subsequent integration into a mature central nervous system have been shown to occur in all vertebrate species examined to date. However, the situation in insects is less clear and, in particular, it has been reported that there is no proliferation in the Drosophila adult brain. Results We report here, using clonal analysis and 5'-bromo-2'-deoxyuridine (BrdU labelling, that cell proliferation does occur in the Drosophila adult brain. The majority of clones cluster on the ventrolateral side of the antennal lobes, as do the BrdU-positive cells. Of the BrdU-labelled cells, 86% express the glial gene reversed polarity (repo, and 14% are repo negative. Conclusion We have observed cell proliferation in the Drosophila adult brain. The dividing cells may be adult stem cells, generating glial and/or non-glial cell types.

Full Text Available The target of monetary policy is generally set as to create an environment of manageable employment and affordable long-term interest rates. However, priorities of central banks may differ depending on economic and financial circumstances of individual countries. Modern approaches to monetary policy transmission can be grouped under two headings, Money View and Credit View. The money view concentrates on interest rates to explain the effects of monetary policy on aggregate spending by creating an interest rate channel. The credit channel transmission approach focuses on the supply of credits by banks following a monetary policy shift in interest rates. In 2010, the Central Bank of Turkey (CBT developed an interest rate corridor shaped by one-week and overnight repo lending to the financial banks to absorb excessive volatility caused by short-term capital inflows. Under this framework, the CBT implements its monetary policy in two ways; firstly it can alter the interest rates of weekly repo as well as O/N lending rate. Secondly, it can configure the funding structure it provides to the financial intermediaries. In such a framework, the interest rate transmission mechanism has been operated by two benchmark interest rates, one of which is the weighted average of the cost of funds provided by the CBT and the other is the interest rate in Borsa Istanbul (BIST money market transactions at an overnight maturity. There is a strong co-movement between the interest rates and they are affected by the movements in the CBT lending rate in both directions. Interest rates applied to deposits and loans by banks are affected by the policy rate (CBT Average Funding Rate and the market rate (BIST O/N Repo Rate.

SECURITIZATION AS A TOOL OF BANK LIQUIDITY AND FUNDING MANAGEMENT BEFORE AND AFTER THE CRISIS: THE CASE OF THE EU

Directory of Open Access Journals (Sweden)

Olga Teplova

2013-02-01

Full Text Available Before the financial crisis securitization was commonly considered an efficient way of replacing illiquid assets with liquid securities (ABS, in which the risk was supposed to be adequately compensated by the tranching techniques. However, with the emergence of the crisis investors became more risk aversive and reluctant to incur ABS due to the rapidly deteriorating quality of the underlying assets caused by poor macroeconomic fundamentals. The limited adverse effects of the poor collateral performance is the main reason why chances for recovery of the ABS market in the EU are estimated more highly than in the USA. The analysis indicates that, driven by the ECB repo operations, the securitization market has almost lost the pre-crisis motives behind the issuance of ABS. Banks’ attitudes toward securitization as a refinancing tool and a mechanism to extract additional profit underwent a shift. As the findings of the article suggest, after the crisis securitization is widely seen by banks as a liquidity tool within the frame of repo deals with the ECB, and to a lesser extent as a refinancing tool. Market regulation contributed considerably to this shift.

Mycobacteriophages are viruses that infect mycobacterial hosts such as Mycobacterium smegmatis and Mycobacterium tuberculosis. All mycobacteriophages characterized to date are dsDNA tailed phages, and have either siphoviral or myoviral morphotypes. However, their genetic diversity is considerable, and although sixty-two genomes have been sequenced and comparatively analyzed, these likely represent only a small portion of the diversity of the mycobacteriophage population at large.

Effect of short-term intravenous ascorbic acid on reducing ferritin in hemodialysis patients.

Science.gov (United States)

Jalalzadeh, M; Shekari, E; Mirzamohammadi, F; Ghadiani, M H

2012-05-01

Resistance to recombinant erythropoietin (rEPO) in hemodialysis patients may be due to inadequate iron recruitment and defect in iron use. In this cross over randomized clinical trial, 30 hemodialysis patients with serum ferritin levels of ≥500 ng/ml, hemoglobin ≤11.0 g/dl, and transferrin saturation (TSAT) of 20% or less were administrated intravenous iron (50-100 mg/wk) and rEPO (120-360 U/kg/wk) for 6 months. Patients were excluded if there was a clear explanation for rEPO hyporesponsiveness. Patients were divided into two groups. Group1 received standard care and 500 mg of intravenous ascorbic acid (IVAA) with each dialysis session in the first week of each month for a total of 3 months. Group 2 received standard care only. After 2 month washout period, groups were crossed over. Each month hemoglobin (Hb) was assessed. Iron, TIBC (transferrin iron binding capacity), TSAT, iPTH (intact parathyroid hormone), liver enzymes, albumin and cholesterol levels were measured every 3 months. After 3 months of intervention, Hb significantly increased from 10.11 to 12.19 g/dl (P <0 0.001; 95% confidence interval [CI] 2.7-1.4) and TSAT increased from 18.9 to 28.1% (P = 0.008; 95% CI 0.09-3), while ferritin and serum iron declined significantly from 1391 to 938 ng/ml (P = 0.001; 95% CI 216-689), 97.2 to 64.6 (P = 0.001; 95% CI 14.8-50.4) in the study group. Change of Hb over time in IVAA group was significant (P < 0.0005). There were significant differences between two groups in change of Hb level over time (P < 0.0005) and treatment effect (P = 0.002). Baseline laboratory tests were similar in the two groups and there was no carry over effect at phase 2. We showed that low amount of IVAA could reduce ferritin level and enhance Hb and TSAT, suggesting improved iron utilization.

Is pain assessment feasible as a performance indicator for Dutch nursing homes? A cross-sectional approach.

Science.gov (United States)

Boerlage, Anneke A; Masman, Anniek D; Hagoort, Jacobus; Tibboel, Dick; Baar, Frans P M; van Dijk, Monique

2013-03-01

Quality of care gains transparency with the help of performance indicators. For Dutch nursing homes, the current set of performance indicators does not include pain. To determine the feasibility of pain assessment as performance indicator, information about pain prevalence and analgesic prescription in one nursing home was collected. Within the time span of 3 days, pain intensity was measured in 91% of the residents (201 out of 221), either with a numeric rating scale, a verbal rating scale, or the Rotterdam Elderly Pain Observation Scale (REPOS). Numerical rating was used for 72%, verbal rating for 3%, and REPOS observation for 25% of the residents. Pain was substantial in 65 residents (32%), who received the following analgesic prescription: World Health Organization (WHO) step 1, 45%; WHO step 3, 12%; and neuroactive agents, 5%. Thirty-eight percent of these residents were in pain and received no analgesics. Residents with substantial pain significantly more often received analgesics (p = .007). Results suggest that pain assessment is feasible in a nursing home and would stimulate staff attention to pain. Further investigation is necessary to find out if a pain algorithm is feasible and will lead to improved pain treatment. Copyright © 2013 American Society for Pain Management Nursing.

A variety of logical frameworks support the use of higher-order abstract syntax in representing formal systems; however, each system has its own set of benchmarks. Even worse, general proof assistants that provide special libraries for dealing with binders offer a very limited evaluation of such libraries, and the examples given often do not exercise and stress-test key aspects that arise in the presence of binders.

Introduction : Lipoma is one of the most common benign mesenchymal tumor which can occur in almost in all organs of the body where fat normally exists, so called as universal tumor or ubiquitous tumor. Lipomas are slow growing that rarely reach a size more than 2-3cms. Lesions larger than 5cms, so called giant lipomas are seldom found inside the muscle compressing nervous-vascular structures. The large and deep seated lipomas represent a real diagnostic and therapeutic challenge. Case repo...

Librarianship is a service profession and not a bottom-line oriented business. As such, librarians don't normally assign a high priority to efficiency of operations; however, opportunities to improve daily jobs and enhance services are being overlooked every day. Advances in technology drive change at a rapid pace and keeping up is both expensive and time consuming. Tight budgets have made keeping up with technology especially difficult. And while some activities in libraries, such as in-person ready reference and circulation of books and journals have declined, many libraries continue to repo

Increased fragility has been described in humans with polycythemia vera (PV). Herein, we describe an osteoporotic phenotype associated with decreased osteoblast activity in a mouse model of PV and another mouse of polycythemia and elevated circulating erythropoietin (EPO). Our results are important for patients with PV or those treated with recombinant EPO (rEPO). PV and other myeloproliferative syndromes have been recently associated with an increased risk for fractures. However, the presence of osteoporosis in these patients has not been well documented. EPO, a hormone primarily known to stimulate erythropoiesis, has been shown recently to regulate bone homeostasis in mice. The aim of this study was to examine the bone phenotype of a mouse model of PV and compare it to that of animals with polycythemia caused by elevated circulating EPO. Bone mass and remodeling were evaluated by micro-computed tomography and histomorphometry. The JAK2(V617F) knock-in mouse, a model of human PV, manifests polycythemia and low circulating EPO levels. Results from this mouse were compared to wild type (wt) controls and the tg6 transgenic mouse that shows polycythemia caused by increased constitutive expression of EPO. Compared to wt, both JAK2(V617F) and tg6 mice had a decrease in trabecular bone mass. Tg6 mice showed an additional modest decrease in cortical thickness and cortical bone volume per tissue volume (P Polycythemia caused by chronically elevated circulating EPO also results in bone loss, and implications on patients treated with rEPO should be evaluated.

Non-abelian Z-theory: Berends-Giele recursion for the α{sup ′}-expansion of disk integrals

We present a recursive method to calculate the α{sup ′}-expansion of disk integrals arising in tree-level scattering of open strings which resembles the approach of Berends and Giele to gluon amplitudes. Following an earlier interpretation of disk integrals as doubly partial amplitudes of an effective theory of scalars dubbed as Z-theory, we pinpoint the equation of motion of Z-theory from the Berends-Giele recursion for its tree amplitudes. A computer implementation of this method including explicit results for the recursion up to order α{sup ′7} is made available on the website repo.or.cz/BGap.git.

The aim of the work was the development of a module for the code RepoTREND that allows the evaluation of radiation exposure in the biosphere. The selection of the characteristics relevant for the risk assessment is described. The program module bioTREND is based on the results of fission product release and dispersion calculations and a separate biosphere modeling. Exposure data (annual effective doses and organ doses) can be calculated for individuals and collectives. Optional is the calculation of radiotoxicity concentrations and radiotoxicity fluxes. Several recommendations for the improvement of the calculation module are included.

Factors Impacting Bank Net Interest Margin and the Role of Monetary Policy: Evidence from Turkey

Directory of Open Access Journals (Sweden)

Muhammed Hasan Yılmaz

2017-10-01

Full Text Available In this study, we investigate factors affecting net interest margin (NIM of commercial banks in Turkey. Especially, our results highlight the relation between unconventional monetary policy shocks and bank margins. To this end, first, we conduct an identification analysis about which parameters of asymmetric interest corridor framework are important in explaining variations in NIM. Using industry-level data, we show that there exists a pass through from BIST interbank overnight repo/reverse repo market rate and weighted average cost of funding (WACF to bank loan and deposit rates. As a result of reduced-form Vector Autoregression (VAR analysis we find the existence of a transmission mechanism from BIST rate and WACF to commercial loan rate, consumer loan rate and deposit rate. Same pass through to loan and deposit rates is also shown in individual bank level with the Panel Vector Autoregression (Panel VAR analysis in the case of 16 commercial banks in Turkey during the period 2011Q1-2016Q1. After the identification analysis, we examine the relationship between NIM and policy rates through System Generalized Method of Moments (GMM techniques by controlling bank specific, industry related and macroeconomic factors. We find that a change in the monetary policy rate has significant and positive impact on NIM. Among bank-specific factors, equity ratio and operating expenses are found to be significantly affecting NIM during the sample period. Our empirical findings also stress the significance of lag values of NIM. Estimations conducted with standardized variables indicate that economic significance of lag values and bank specific variables are larger than that of policy.

The glucuronyltransferase GlcAT-P is required for stretch growth of peripheral nerves in Drosophila.

Science.gov (United States)

Pandey, Rahul; Blanco, Jorge; Udolph, Gerald

2011-01-01

During development, the growth of the animal body is accompanied by a concomitant elongation of the peripheral nerves, which requires the elongation of integrated nerve fibers and the axons projecting therein. Although this process is of fundamental importance to almost all organisms of the animal kingdom, very little is known about the mechanisms regulating this process. Here, we describe the identification and characterization of novel mutant alleles of GlcAT-P, the Drosophila ortholog of the mammalian glucuronyltransferase b3gat1. GlcAT-P mutants reveal shorter larval peripheral nerves and an elongated ventral nerve cord (VNC). We show that GlcAT-P is expressed in a subset of neurons in the central brain hemispheres, in some motoneurons of the ventral nerve cord as well as in central and peripheral nerve glia. We demonstrate that in GlcAT-P mutants the VNC is under tension of shorter peripheral nerves suggesting that the VNC elongates as a consequence of tension imparted by retarded peripheral nerve growth during larval development. We also provide evidence that for growth of peripheral nerve fibers GlcAT-P is critically required in hemocytes; however, glial cells are also important in this process. The glial specific repo gene acts as a modifier of GlcAT-P and loss or reduction of repo function in a GlcAT-P mutant background enhances VNC elongation. We propose a model in which hemocytes are required for aspects of glial cell biology which in turn affects the elongation of peripheral nerves during larval development. Our data also identifies GlcAT-P as a first candidate gene involved in growth of integrated peripheral nerves and therefore establishes Drosophila as an amenable in-vivo model system to study this process at the cellular and molecular level in more detail.

For the long-term safety analysis of final nuclear waste repositories the transport of pollutants from the repository into the biosphere three mostly independent subsystems are considered: the near field, the geosphere and the biosphere. Normally rocks include fissures or other disturbances. Porous materials in the rock matrix have usually a high water content and acts as storage for pollutants due to sorption and diffusion processes. The aim of the project is the development of calculation modules for the code RepoTREND that simulate the pollutant transport in saturated fissured-porous media taking into account the effect of colloids. FRAME describes the pollutant dispersion in a fissured-porous medium and COFRAME the colloid influenced transport in a fissured-porous medium.

Nevertheless, a new tool is required for pain assessment needs in retrospective studies.Methods: The postoperative pain episodes, during the first postoperative day, of three patient groups were analyzed. Each pain episode was assessed by a visual analog scale, numerical rating scale, verbal rating scale, and a new tool – pain point system scale (PPSS – based on the analgesics administered. The type of analgesic was defined based on the authors’ clinic protocol, patient comorbidities, pain assessment tool scores, and preadministered medications by an artificial neural network system. At each pain episode, each patient was asked to fill the three pain scales. Bartlett’s test and Kaiser–Meyer–Olkin criterion were used to evaluate sample sufficiency. The proper scoring system was defined by varimax rotation. Spearman’s and Pearson’s coefficients assessed PPSS correlation to the known pain scales.Results: A total of 262 pain episodes were evaluated in 124 patients. The PPSS scored one point for each dose of paracetamol, three points for each nonsteroidal antiinflammatory drug or codeine, and seven points for each dose of opioids. The correlation between the visual analog scale and PPSS was found to be strong and linear (rho: 0.715; P <0.001 and Pearson: 0.631; P < 0.001.Conclusion: PPSS correlated well with the known pain scale and could be used safely in the evaluation of postoperative pain in retrospective studies.Keywords: pain scale, retrospective studies, pain point system

Water is used as a coolant and can be introduced either by the top or the bottom of the bed at a determined temperature. Due to heterogeneous power distribution within the bed, two definitions for the critical heat flux are proposed: the classical mean value and the local flux (much higher). Even in the first case, the measured dryout heat flux is higher than the Lipinsky 1-D flux. Temperature curve analyses show that the dryout phenomenon is very local, therefore one should be careful about the right flux definition to use. As the injected power is being increased stepwise, steady temperature stages above saturation temperature before dryout can be observed. A discussion is proposed. For some very high values of the induction power, some spheres melted together, leading to a bigger non-porous region. Even if the local temperature went over 1300 C, the bed was still coolable and the critical heat flux value was not impacted. Some parametric studies led to the following conclusions: bottom coolant injection leads to a twice time higher critical flux than by top injection, the influence of the height of the water pool above debris bed is negligible, a sub-cooled liquid injection has no influence on the coolability. Fluidization of surface particles is also discussed. The MC3D-REPO model assumes a thermal equilibrium between the three phases, which gives results in agreement with experiments until dryout occurs.

The impact of monetary policy on the economic growth of a small and open economy: The case of South Africa

Directory of Open Access Journals (Sweden)

V Khabo

2014-08-01

Full Text Available This study evaluates the impact of monetary policy on the economic growth of a small and open economy like that of South Africa. Structuralists contend that changes in money supply (M3 and inflation (CPI are not significantly related to changes in economic growth (GDP, while orthodox economists argue that they are. Stucturalists also hold that monetary authorities cannot control M3, whereas orthodox economists believe they can. To structuralists, when monetary authorities pursue an expansionary policy, the opposite effect is achieved. Orthodox economists counter this argument. The ADT test statistic against the McKinnon critical values was used and it was found (i that money supply changes and inflation are significantly related to changes in economic growth, and (ii whereas monetary authorities can control M3 through the repo rate,  they cannot keep it within set targets.

Tools for Reproducibility and Extensibility in Scientific Research

2018-01-01

Open inquiry through reproducing results is fundamental to the scientific process. Contemporary research relies on software engineering pipelines to collect, process, and analyze data. The open source projects within Project Jupyter facilitate these objectives by bringing software engineering within the context of scientific communication. We will highlight specific projects that are computational building blocks for scientific communication, starting with the Jupyter Notebook. We will also explore applications of projects that build off of the Notebook such as Binder, JupyterHub, and repo2docker. We will discuss how these projects can individually and jointly improve reproducibility in scientific communication. Finally, we will demonstrate applications of Jupyter software that allow researchers to build upon the code of other scientists, both to extend their work and the work of others.    There will be a follow-up demo session in the afternoon, hosted by iML.

Solubilities of some hydrous REE phosphates with implications for diagenesis and sea water concentrations

International Nuclear Information System (INIS)

Jonasson, R.G.; Bancroft, G.M.; Nesbitt, H.W.

1985-01-01

Solubility product determinations suggest that the hydrous phosphates of the rare earths, REPO 4 .xH 2 O, are important in controlling the sea water REE concentrations. Two of these solids, rhabdophane, (P6 2 22) and 'hydrous xenotime', (I4 1 /amd), have been synthesized at 100 C via the acid hydrolysis of the respective REE pyrophosphate. The solubility products at infinite dilution were determined to be pK 0 = 24.5, (La at 25 C); 26.0, (Pr at 100 C); 25.7, (Nd at 100 C); and 25.5, (Er at 100 C). On the basis of calculations involving the reaction of Re 3+ with apatite to form the hydrous phosphate, the lanthanum concentration in sea water is predicted to be about 140 pmol/L. Laboratory experiments support the hypothesis that apatite is a substrate for reactions with dissolved REE. (author)

Accelerating Inspire

AUTHOR|(CDS)2266999

2017-01-01

CERN has been involved in the dissemination of scientific results since its early days and has continuously updated the distribution channels. Currently, Inspire hosts catalogues of articles, authors, institutions, conferences, jobs, experiments, journals and more. Successful orientation among this amount of data requires comprehensive linking between the content. Inspire has lacked a system for linking experiments and articles together based on which accelerator they were conducted at. The purpose of this project has been to create such a system. Records for 156 accelerators were created and all 2913 experiments on Inspire were given corresponding MARC tags. Records of 18404 accelerator physics related bibliographic entries were also tagged with corresponding accelerator tags. Finally, as a part of the endeavour to broaden CERN's presence on Wikipedia, existing Wikipedia articles of accelerators were updated with short descriptions and links to Inspire. In total, 86 Wikipedia articles were updated. This repo...

Time and frequency structure of causal correlation networks in the China bond market

Science.gov (United States)

Wang, Zhongxing; Yan, Yan; Chen, Xiaosong

2017-07-01

There are more than eight hundred interest rates published in the China bond market every day. Identifying the benchmark interest rates that have broad influences on most other interest rates is a major concern for economists. In this paper, a multi-variable Granger causality test is developed and applied to construct a directed network of interest rates, whose important nodes, regarded as key interest rates, are evaluated with CheiRank scores. The results indicate that repo rates are the benchmark of short-term rates, the central bank bill rates are in the core position of mid-term interest rates network, and treasury bond rates lead the long-term bond rates. The evolution of benchmark interest rates from 2008 to 2014 is also studied, and it is found that SHIBOR has generally become the benchmark interest rate in China. In the frequency domain we identify the properties of information flows between interest rates, and the result confirms the existence of market segmentation in the China bond market.

X-ray Absorption Spectroscopy of the Rare Earth orthophosphates

Shuh, D.K.; Terminello, L.J.; Boatner, L.A.; Abraham, M.M.

1993-06-01

X-ray Absorption Spectroscopy (XAS) of the Rare Earth (RE) 3d levels yields sharp peaks near the edges as a result of strong, quasi-atomic 3d 10 4f n → 3d- 9 4f n+1 transitions and these transitions exhibit a wealth of spectroscopic features. The XAS measurements of single crystal REPO 4 (RE = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er) at the 3d edge were performed in the total yield mode at beam line 8-2 at the Stanford Synchrotron Radiation Laboratory (SSRL). The XAS spectra of the RE ions in the orthophosphate matrix generally resemble the XAS of the corresponding RE metal. This is not unexpected and emphasizes the major contribution of the trivalent state to the electronic transitions at the RE 3d edges. These spectra unequivocally identify the transitions originating from well-characterized RE cores and correlate well with previous theoretical investigations

Thousands of men in four Latin countries choose to have vasectomies; machismo is no barrier.

Science.gov (United States)

1975-12-01

The acceptability of vasectomy in 4 Latin American countries is repo rted. The unenthusiastic reception of vasectomy in Latin America is apparently due to a paucity of male sterilization programs and not to machismo. The 1st vasectomy program in Latin America was established in Bogota, Colombia, in 1970. This was followed by programs in Costa Rica (1971), El Salvador (1972), and Guatemala (1973). Upon expansion of the Colombian program from 1 city to 9 cities, the number of voluntary vasectomies increased from 100 to 560. 235 vasectomies were performed in the 1st 6 months of the Costa Rican program, and 278 were performed in the 1st 9 months of the Guatemalan program. During the 1st 2 years of the program in El Salvador, the monthly average of operations performed rose from 3 to 19. In El Salvador at least, vasectomy was acceptable to men aged 22-69 years, with 2-20 living children, and from all types of occupations.

HappyFace as a monitoring tool for the ATLAS experiment

CERN Document Server

AUTHOR|(INSPIRE)INSPIRE-00367045; Yahyapour, Ramin

The importance of monitoring on HEP grid computing systems is growing due to a significant increase in their complexity. Computer scientists and administrators have been studying and building effective ways to gather information on and clarify a status of each local grid infrastructure. The HappyFace project aims at making the above-mentioned workflow possible. It aggregates, processes and stores the informa- tion and the status of different HEP monitoring resources into the common database of HappyFace. The system displays the information and the status through a single interface. However, this model of HappyFace relied on the monitoring resources which are al- ways under development in the HEP experiments. Consequently, HappyFace needed to have direct access methods to the grid application and grid service layers in the dif- ferent HEP grid systems. To cope with this issue, we use a reliable HEP software repos- itory, the CernVM File System. We propose a new implementation and an architecture of HappyFace, ...

Tepavac Rajko

2012-03-01

Full Text Available The main task of monetary policy of our central bank is to achieve and preserve stability of prices and currency. Targeted inflation rate has been chosen as operating instrument for gradual realization of low and stable inflation, along with elimination of inflation expectations. Also, a specific inflation corridor is chosen to ensure operations, transparency and ex ante effects of monetary policy. The paper presents analysis on whether there really is a restrictive monetary policy, deflections of real inflation from the programmed one, level of 'restrictiveness' of monetary policy and behavior of bank loans, money supply, nominal and real economic growth. Analysis is carried out and criticism of concepts of monetary regulation of mandatory bank reserves, blocking of financial bank potential through monetary regulation instruments, but also relations between central and business banks through open market policy. Criticism of repo operations and complete disappearance of selective credit policy is provided as well. The problem of almost embedded insolvency of economic sector is highlighted.

Full Text Available For the past several years, Idaho National Laboratory’s MOOSE framework team has employed modern software engineering techniques (continuous integration, joint application/framework source code repos- itories, automated regression testing, etc. in developing closed-source multiphysics simulation software (Gaston et al., 'Journal of Open Research Software' vol. 2, article e10, 2014. In March 2014, the MOOSE framework was released under an open source license on GitHub, significantly expanding and diversifying the pool of current active and potential future contributors on the project. Despite this recent growth, the same philosophy of concurrent framework and application development continues to guide the project’s development roadmap. Several specific practices, including techniques for managing multiple repositories, conducting automated regression testing, and implementing a cascading build process are discussed in this short paper. Special attention is given to describing the manner in which these practices naturally synergize with the GitHub API and GitHub-specific features such as issue tracking, Pull Requests, and project forks.

2006-01-01

This paper examines the impact of a monetary policy shock on output, prices, and the nominal effective exchange rate for Kenya using data during 1997–2005. Based on techniques commonly used in the vector autoregression literature, the main results suggest that an exogenous increase in the short-term interest rate tends to be followed by a decline in prices and appreciation in the nominal exchange rate, but has insignificant impact on output. Moreover, the paper finds that variations in the sh...

In the framework of the European project EuCARD, the High Field Magnet project, led by a CERN-CEA collaboration, implied the development of a large aperture Nb$_{3}$Sn dipole magnet called FRESCA2. The magnet uses four double-pancake block-type coils, each about 1.5 m long. In order to characterize strand and cable properties, as well as to qualify the coil fabrication process, CERN started in 2012 the design and fabrication of the Racetrack Model Coil (RMC) magnet, a short model magnet using the same cable as FRESCA2 magnet with only two flat double-pancake coils about 0.8 m long. In 2013, two superconducting coils have been fabricated, making use of two different types of superconductor. In 2014 and 2015, the coils were tested both in a single and in a double-coil configuration in a support structure based on an external aluminum shell pre-loaded with water-pressurized bladders. In this paper, we describe the design of the RMC magnet and its coils, provide the main parameters of the superconductor, and repo...

Sanja Dudaković

2014-12-01

Full Text Available The aim of this paper is to throw light on the relationship between credit spread changes and past changes of U.S. macro-financial variables when invariants do not have Gaussian distribution. The first part presents the empirical analysis which is based on 10-year AAA corporate bond yields and 10-year Treasury bond yields. Explanatory variables include lagged U.S. leading index, Russell 2000 returns, BBB bond price changes interest rate swaps, exchange rates EUR/ USD, Repo rates, S& P 500 returns and S&P 500 volatility, Treasury bill changes, liquidity index-TRSW, LIBOR rates, Moody’s default rates; credit spread volatility and Treasury bills volatility. The proposed dynamical model explains 73% of the U.S. credit spread variance for the period 1999:07-2013:07. The second part of the article introduces the parameter estimation method based on higher order cumulants. It is demonstrated empirically that much of the information about variability of Credit Spread can be extracted from higher order cumulant function (85%.

The Associative Memory (AM) system of the FTK processor has been designed to perform pattern matching using the hit information of the ATLAS silicon tracker. The AM is the heart of the FTK and it finds track candidates at low resolution that are seeds for a full resolution track fitting. To solve the very challenging data traffic problems inside the FTK, multiple designs and tests have been performed. The currently proposed solution is named the “Serial Link Processor” and is based on an extremely powerful network of 2 Gb/s serial links. This paper reports on the design of the Serial Link Processor consisting of the AM chip, an ASIC designed and optimized to perform pattern matching, and two types of boards, the Local Associative Memory Board (LAMB), a mezzanine where the AM chips are mounted, and the Associative Memory Board (AMB), a 9U VME board which holds and exercises four LAMBs.

DIMAC (A DIspersion Metallic fuel performance Analysis Code) is a computer program for simulating the behavior of dispersion fuel rods under normal operating conditions of HYPER. It computes the one-dimensional temperature distribution and the thermo-mechanical characteristics of fuel rod under the steady state operation condition, including the swelling and rod deformation. DIMAC was developed based on the experience of research reactor fuel. DIMAC consists of the temperature calculation module, the mechanical swelling calculation module, and the fuel deformation calculation module in order to predict the deformation of a dispersion fuel as a function of power history. Because there are a little of available U-TRU-Zr or TRU-Zr characteristics, the material data of U-Pu-Zr or Pu-Zr are used for those of U-TRU-Zr or TRU-Zr. This report is mainly intended as a user's manual for the DIMAC code. The general description on this code, the description on input parameter, the description on each subroutine, the sample problem and the sample input and partial output are written in this repo0008.

Methods: Overall, 73 family physicians participated and completed the study. Our study comprised seven simulated case vignettes, three behavioral experiments, and two validated surveys. Behavioral experiments and surveys incorporated an economic framework to determine risk preferences and biases (e.g., ambiguity aversion, willingness to take risks. The primary outcome was making the correct decision of anticoagulation therapy. Secondary outcomes included medical errors in the management of AF for stroke prevention. Results: Overall, 23.3% (17/73 of the family physicians elected not to escalate the therapy from antiplatelets to anticoagulation when recommended by best practice guidelines. A total of 67.1% of physicians selected the correct therapeutic options in two or more of the three simulated case vignettes. Multivariate

Simplified method for the determination of strontium-90 in large amounts of bone-ash; Methode simplifiee de dosage du strontium 90 sur des quantites importantes de cendres d'os

The principle of the determination is based on a 3-step process: 1) concentrating the strontium by attacking the ash with nitric acid; 2) elimination of residual phosphoric ions by a double precipitation of strontium oxalate; and 3) extraction of yttrium 90, counted in the oxalate form. The advantages of the method: -) using simple techniques it makes it possible to process 50 g of ash; -) the initial concentration of strontium considerably reduces the volume of the solutions as well as the size of precipitates handled. Fuming nitric acid is used in a specially designed burette. (authors) [French] Le principe du dosage repos sur un procede en 3 etapes: 1) Concentration du strontium par une attaque nitrique des cendres; 2) Elimination des ions phosphoriques restants par une double precipitation de l'oxalate de strontium. 3) Extraction de l'yttrium 90, compte sous forme d'oxalate. Interet de la methode: dans des conditions techniques simples, elle permet le traitement de 50 g de cendres d'os; la concentration initiale du strontium reduit notablement le volume des solutions ainsi que l'importance des precipites manipules.

Blood saving strategies during paediatric spinal surgery often include recombinant erythropoietin (rEPO) and antifibrinolytic therapy (AFT). The goal of this study was to investigate additional preventive factors involved in the risk of blood transfusion. This prospective study was designed with the aim of identifying factors associated with the perioperative (defined as the intraoperative and the first postoperative day) probability of homologous red cell transfusion during scoliosis surgery in children operated during a one year period in our institution. The predictors analysed were: age, weight less than the 3rd percentile (W 255 minutes. ROC analysis for the latter model found an area under the curve of 0.9 (95% confidence interval: 0.8-0.97). The accuracy of the model was 92.3% (97.4% for non-transfusion and 69.2% for transfusion). Multivariate sensitivity analysis excluding patients with no preoperative administration of EPO found similar results. The current results indicate that optimising nutritional status might prevent allogenic blood transfusion and requires further investigation.

The principal aim of this paper is to examine whether Serbian companies employ derivatives to manage risk and to what degree, and to explore the main rationale behind the companies' not employing these instruments, as well as to suggest possible enhancements of risk management practices. Furthermore, we have investigated the key reasons why financial derivatives are very useful for Serbian companies for hedging financial risks. Additionally, this paper provides a comparative overview of the use of derivatives between Serbian companies and the companies in Croatia and Slovenia in order to ascertain whether Serbian companies employ derivatives in order to manage risk to the same degree as their Croatian and Slovenian counterparts. This paper will include findings and provide evidence that FX rate and referent interest rates (such as 1w- 2w repo rate, Beonia and Belibor are markedly volatile, which opens vast possibilities for the use of financial derivatives, given that these financial parameters determine the price of a credit arrangement for companies and the quality of import and export cash flows.

Lanthanide(Ln)doped materials find potential applications in the fields of lasers, optical amplifiers, phosphors, display devices, etc., due to their characteristic energy level schemes. These materials found wide useful in the development of plasma display panels(PDP), field emission displays(FED)and electro luminescent panel applications. Recently, REPO{sub 4}(RE=Y, La, Gd, Lu)materials have attracted much attention in PDP applications due to their high thermal and chemical stability as well as high luminescence efficiency under VUV excitation. Tricolor inorganic luminescence materials are used in PDP to emit red, green and blue light. PDP phosphors emit visible light under VUV excitation. The VUV pump photon is absorbed by the host lattice and color purity are most essential. It is thus necessary either to further improve the luminescence properties, or to develop new phosphors. It is possible to tune the intensity of red emission by modifying the neighboring network design around Eu{sup 3+} ions on introducing other atoms such as Ca, Sr, Ba, Zn, Al, Li, Sc, Bi, La, Gd, etc., into the ortho phosphate host lattice. The prepared samples are characterized by XRD, SEM, photoluminescence excitation, photoluminescence emission and lifetime measurements. The results are also compared with those of earlier reported works.

Analysis pipelines are an essential part of bioinformatics research, and ad hoc pipelines are frequently created by researchers for prototyping and proof-of-concept purposes. However, most existing pipeline management system or workflow engines are too complex for rapid prototyping or learning the pipeline concept. A lightweight, user-friendly and flexible solution is thus desirable. In this study, we developed a new pipeline construction and maintenance tool, PipelineDog. This is a web-based integrated development environment with a modern web graphical user interface. It offers cross-platform compatibility, project management capabilities, code formatting and error checking functions and an online repository. It uses an easy-to-read/write script system that encourages code reuse. With the online repository, it also encourages sharing of pipelines, which enhances analysis reproducibility and accountability. For most users, PipelineDog requires no software installation. Overall, this web application provides a way to rapidly create and easily manage pipelines. PipelineDog web app is freely available at http://web.pipeline.dog. The command line version is available at http://www.npmjs.com/package/pipelinedog and online repository at http://repo.pipeline.dog. ysun@kean.edu or xing@biology.rutgers.edu or ysun@diagnoa.com.

Full Text Available El modelo de desarrollo urbanístico-turístico de Barcelona en los últimos quince años ha obtenido un éxito extraordinario en cuanto a número de visitantes, pernoctaciones, llegadas de pasajeros de cruceros, incremento de camas hoteleras y visitas a monumentos de pago. De este modo, la ciudad se ha convertido en una de las ciudades más visitadas de Europa y de mayor crecimiento del número de turistas. Pero, este crecimiento cuantitativo ha generado masificación turística, concentración en determinados barrios, enfrentamiento por el uso del espacio urbano entre turistas y residentes, además de generar algunas deficiencias infraestructurales como la conectividad y la intermodalidad. Estos problemas amenazan la posición competitiva de Barcelona. Este artículo revisa la competitividad entre las ciudades, comparando Barcelona con otras diez ciudades europeas. A partir de un análisis cualitativo a los players internos y externos y de un Estudio Delphi con players externos, se exploran las correcciones que hay que introducir en el modelo y los vectores del repo- sicionamiento. Esta nueva posición refuerza la competitividad en base a tres objetivos: la sostenibilidad del modelo, la gestión integral de la metrópolis turística y su gobernanza, y la orientación al cliente.

Full Text Available Background: Long QT syndromes (LQT are genetic abnormalities of ventricular repo-larization, with an estimated incidence of about one per 10000 births. It is characterized by prolongation of the QT interval in electrocardiogram (EKG and associated with a high risk for syncope and sudden death in patients. Type of this syndrome is association with congenital deafness. Our objective was to evaluate QT interval in children with congenital deafness.Methods: For 219 patients referred to Imam Khomeini Hospital audiometric clinic in 2011, questionnaire were completed. A total of 23 congenitally deaf children were incl-uded. All patients’ examinations were done by a pediatric cardiologist. Electrocardio-gram is conducted in all children (23 patients with sever and deep congenital deafness. Then the QT interval was measured based on Bazett’s formula. Echocardiography was also performed in these children to assess left ventricular function and the presence of mitral valve prolapse.Results: The overall patients were two hundred and nineteen children. A total of twenty three congenitally deaf children were included and electrocardiogram was obtained. Three children had obviously prolonged QTc (0.48±0.02 second. The median age of them was 6.1±5 year, the median weight was 18±11.3 kilogram and the median of QT interval was 0.48±0.02 second.Conclusion: The QT interval obtained 0.48±0.02 second. In the present study we found prolonged QT in congenital deafness, thus we recommend to evaluate the electrocardio-gram of children with congenital deafness.

On Variations in the Level of PER in Glial Clocks of Drosophila Optic Lobe and Its Negative Regulation by PDF Signaling.

We show that the level of the core protein of the circadian clock Period (PER) expressed by glial peripheral oscillators depends on their location in the Drosophila optic lobe. It appears to be controlled by the ventral lateral neurons (LNvs) that release the circadian neurotransmitter Pigment Dispersing Factor (PDF). We demonstrate that glial cells of the distal medulla neuropil (dMnGl) that lie in the vicinity of the PDF-releasing terminals of the LNvs possess receptors for PDF (PDFRs) and express PER at significantly higher level than other types of glia. Surprisingly, the amplitude of PER molecular oscillations in dMnGl is increased twofold in PDF-free environment, that is in Pdf 0 mutants. The Pdf 0 mutants also reveal an increased level of glia-specific protein REPO in dMnGl. The photoreceptors of the compound eye (R-cells) of the PDF-null flies, on the other hand, exhibit de-synchrony of PER molecular oscillations, which manifests itself as increased variability of PER-specific immunofluorescence among the R-cells. Moreover, the daily pattern of expression of the presynaptic protein Bruchpilot (BRP) in the lamina terminals of the R-cells is changed in Pdf 0 mutant. Considering that PDFRs are also expressed by the marginal glia of the lamina that surround the R-cell terminals, the LNv pacemakers appear to be the likely modulators of molecular cycling in the peripheral clocks of both the glial cells and the photoreceptors of the compound eye. Consequently, some form of PDF-based coupling of the glial clocks and the photoreceptors of the eye with the central LNv pacemakers must be operational.

Added mass induced by an uncompressible ideal and still fluid on a structure a bibliography; Prise en compte d`un fluide parfait incompressible au repos comme masse ajoutee sur une structure. Synthese bibliographique

We first recall the most important definitions about the fluid/structure interaction. We also define some non-dimensional numbers in order to analyze the physical effects in the fluid we have to take into account: viscosity, compressibility, gravity, inertial effect. Then, in the first part called ``Calculation of the added mass: Models``, we explain the equations which allow us to find the added mass on one structure. After that, we deal with the dynamical behaviour of tube bundles immersed in a fluid. We present a two dimensional modelling. Therefore, the fluid structure interaction only takes place in the planes perpendicular to the tube axis. The added mass matrix of the fluid on the whole tubes is built for every kind of cross-section. But we also focus our attention on the special case of circular cross-section. Lastly, when the number of the tubes in the bundle is huge, the direct calculation of the global added mass matrix is impossible: we must use a method of homogenization to describe the global dynamical behaviour of the tube bundles. In particular, the eigenfrequencies of such homogenized medium are determined. We especially focus our attention on the square nuclear fuel bundles immersed in a confined fluid. In the second part called ``Numerical methods used for the fluid structure interaction``, we first tackle the integral methods. However, in these methods, some theoretical and numerical difficulties arise and this fact makes the advantage of a little number of degrees of freedom far less interesting. This leads us to consider the finite element methods. It allows us to determine the added mass matrix of the fluid on the structure expressed with the nodal interpolation functions used by the FE methods. We then propose a discretization of the equations of the movement of tube bundles immersed in a fluid, with or without homogenization. At last, we compare the efficiency of the integral methods to the FE methods. (author). figs., tabs., 54 refs.

Collective Mind: Towards Practical and Collaborative Auto-Tuning

2014-01-01

Full Text Available Empirical auto-tuning and machine learning techniques have been showing high potential to improve execution time, power consumption, code size, reliability and other important metrics of various applications for more than two decades. However, they are still far from widespread production use due to lack of native support for auto-tuning in an ever changing and complex software and hardware stack, large and multi-dimensional optimization spaces, excessively long exploration times, and lack of unified mechanisms for preserving and sharing of optimization knowledge and research material. We present a possible collaborative approach to solve above problems using Collective Mind knowledge management system. In contrast with previous cTuning framework, this modular infrastructure allows to preserve and share through the Internet the whole auto-tuning setups with all related artifacts and their software and hardware dependencies besides just performance data. It also allows to gradually structure, systematize and describe all available research material including tools, benchmarks, data sets, search strategies and machine learning models. Researchers can take advantage of shared components and data with extensible meta-description to quickly and collaboratively validate and improve existing auto-tuning and benchmarking techniques or prototype new ones. The community can now gradually learn and improve complex behavior of all existing computer systems while exposing behavior anomalies or model mispredictions to an interdisciplinary community in a reproducible way for further analysis. We present several practical, collaborative and model-driven auto-tuning scenarios. We also decided to release all material at c-mind.org/repo to set up an example for a collaborative and reproducible research as well as our new publication model in computer engineering where experimental results are continuously shared and validated by the community.

Full Text Available The implementation of modern banking activities involves the realization of investments. Investment is a complex discussion economic category, characterized by a number of features. The types and forms of investment are manifold and can be transformed with account of the state of the economy and the level of development of industrial relations. The faster growth of the financial sector in the economy has stipulated the development of financial investment. Banks as financial and lending institutions actively make financial investments in securities. Banks’ investment in securities pursues a number of purposes which determine the selection of securities for investment and their quality. The article identified the targets of bank investments in securities and their development trends under current conditions on the basis of the analysis of the actual data for 2010–2014. Negative revaluation and the actual decrease in the value of corporate securities of Russian issuers reduce their commercial appeal. Banks refuse to speculate on the stock market in favor of the securities that ensure liquidity. Banks’ investments aim to purchasing securities from the Lombard List of the Bank of Russia in order to obtain loans and participate in the repo transactions. Thus, during the analyzed period, banks’ investments in securities transformed from systemically important assets that generate substantial profit into the mechanism that provides liquidity. It should be noted that a significant part of investment resources of Russian banks services the debt obligations of Russia’s Government. The article also identified a trend of banks’ increasing investment in the participation portfolios of subsidiaries and associated joint stock companies. The official data of the Central Bank of the Russian Federation (Bank of Russia [15], and the Federal State Statistics Service [14] were used as the information base for the study

The objective was to compare the radial strength and expansile precision of self-expanding stents and balloon-expandable stents in a human cadaver bifurcation model. Seven different self-expanding (LUMINEXX, JOSTENT SelfX, JOSTENT SelfX hrf, Sinus-Repo, Sinus SuperFlex, Easy Wallstent, SMART) and four different balloon-expandable stent models (Palmaz, Sinus Stent, SAXX Medium, JOSTENT peripheral), each type 10 stents (total n = 110 stents) were implanted into the common iliac arteries of human cadaver corpses. The maximum stent diameter was 10 mm for all models. After stent implantation, the specimens were filled with silicone caoutchouc. After 24 h, the vascular walls including the stents were removed from the hardened casts. Diameters were taken and the weight of the cast cylinders was measured in air and in purified water to calculate the volume of the bodies (according to Archimedes Law) as a relative but precise degree for the radial strength of the implanted stents. The cylindrical casts of the self-expanding stents showed lower mean diameters (8.2 ± 1.0 mm) and mean volumes (0.60 ± 0.14 ml/cm) than in the balloon-expandable stent group (10.1 ± 0.3 mm and 0.71 ± 0.04 ml/cm, respectively; p < 0.01). The nominal maximum diameter of 10 mm was not achieved in any of the self-expanding stents, but this was achieved in more than 70% (29/40) of the balloon-expandable stent specimens (p < 0.05). The variation between achieved volumes was significantly larger in self-expanding (range: 0.23-0.78 ml/cm) than in balloon-expandable stents (range: 0.66-0.81 ml/cm; p < 0.05). Self-expanding stents presented considerably lower radial expansion force and lower degree of precision than balloon-expandable stents

Full Text Available Este trabajo intenta exponer las dificultades que confronta la autoridad monetaria para ejercer algún grado de control sobre los agregados monetarios, y para ello evalúa la experiencia reciente de una economía abierta y dependiente de un recurso mineral exportable como Venezuela. El trabajo no sólo expone argumentos analíticos, sino además provee evidencia muy sencilla en demostración de que existen numerosas fuentes de endogeneidad de la base monetaria, del multiplicador y de otros agregados más amplios en la economía venezolana. Aunque el Banco Central en Venezuela no viene anunciando ni explicando públicamente la estrategia y el alcance de la política monetaria, el trabajo muestra que la autoridad monetaria se ha movido sigilosamente, en los últimos tiempos, hacia una estrategia de uso de las tasas marcadores de las operaciones de mercado abierto como variable operativa buscando un objetivo final de actividad económica.This work examines the difficulties and formidable challenges faced by monetary authorities to control the behavior of monetary aggregates in an open economy dependent of an exportable natural resource such as Venezuela. The work not only introduces analytical arguments but also provides some empirical evidence that shows the several sources of endogeneity in the monetary base, the multiplier and other wider monetary aggregates in Venezuela. Though the Central Bank currently does not announce a clear strategy and target for the practice of monetary policy, we argue that the monetary authority has recently moved towards a strategy of targeting short-term interest rates. Presumably, the use of the repo rate as a monetary policy instrument is tied to a final target of economic activity.

Le recours aux archives judiciaires pour étudier les habitudes de sommeil

Guillaume Garnier

2009-10-01

Full Text Available Les archives judiciaires possèdent de nombreux attraits, et certains sont parfois insoupçonnés. Les faits relatés dans les actes d’accusation par exemple, mais aussi les déclarations de témoins recèlent de petits détails sur les habitudes de sommeil qui passent souvent inaperçus aux yeux des historiens. Dans un corpus très large (du XVIIIe au xixe siècle on peut ainsi tenter de comprendre les logiques de sommeil : heures de coucher et lever, durée du sommeil, l’apparente vulnérabilité du repos nocturne, les déviances nocturnes, le lieu de sommeil. Mais dans une vue plus globale, les archives aident aussi à déterminer les rythmes nocturnes et notamment la place qu’y tient le sommeil. Les contraintes sociales et politiques, la dureté du travail et de la vie, l’importance de la religion transparaissent aussi pour former une culture spécifique du sommeil préindustriel.Judiciary records have many appealing aspects, some of which one would not suspect. What is related in indictment documents for instance, as well as in evidence statements, contains small details about sleeping habits that often go unnoticed by historians. Out of a very large corpus (from the xviiith till the xixth century, one can try and work out the rationale behind sleep: at what time people go to sleep or wake up, for how long, how vulnerable night sleep seems to be, nocturnal deviances, or where people sleep. But to a larger extent, records also help to determine nocturnal rhythms and more specifically the place that sleep holds in them. Social and political constraints, harshness of working and living conditions, the importance of religion, all show through and convey a specific culture of pre-industrial sleep.

Monazite-type ceramics for conditioning of minor actinides. Structural characterization and properties

International Nuclear Information System (INIS)

Babelot, Carole

2013-01-01

The minor actinides (MA) neptunium, americium, and curium are mainly responsible for the long-term radiotoxicity of the High Active Waste (HAW) generated during the nuclear power operation. If these long-lived radionuclides are removed from the HAW by partitioning and converted by neutron fission (transmutation) into shorter-lived or stable elements, the remaining waste loses most of its long-term radiotoxicity. Thus, partitioning and transmutation (P and T) are considered as attractive options for reducing the burden on geological disposals. As an alternative, these separated MA can also be conditioned (P and C strategy) in specifically adapted ceramics to ensure their safe final disposal over long periods. At the moment, spent fuel elements are foreseen either for direct disposal in deep geological repositories or for reprocessing. The highly active liquid waste that is produced during reprocessing is conditioned industrially using a vitrification process before final disposal. Although the widely used borosilicate glasses meet most of the specifications needed, ceramic host matrices appear to be even more suitable in terms of resistance to corrosion. The development of new materials based on tailor-made highly specific ceramics with extremely stable behavior would make it possible to improve the final storage of long-lived high-level radiotoxic waste. In the framework of this PhD research project, monazite-type ceramics were chosen as promising host matrices for the conditioning of trivalent actinides. The focus on the monazite-type ceramics is justified by their properties such as high chemical durability. REPO 4 ceramics are named monazite for RE = La - Gd (monoclinic symmetry) and xenotime for RE = Tb - Lu and Y (tetragonal symmetry). The objective of this study is to contribute to the understanding of the alteration behavior of such ceramics under the repository conditions. REPO 4 (with RE = La, Eu) is prepared by hydrothermal synthesis at 200 C. Structural

Building Scientific Data's list of recommended data repositories

Science.gov (United States)

Hufton, A. L.; Khodiyar, V.; Hrynaszkiewicz, I.

2016-12-01

When Scientific Data launched in 2014 we provided our authors with a list of recommended data repositories to help them identify data hosting options that were likely to meet the journal's requirements. This list has grown in size and scope, and is now a central resource for authors across the Nature-titled journals. It has also been used in the development of data deposition policies and recommended repository lists across Springer Nature and at other publishers. Each new addition to the list is assessed according to a series of criteria that emphasize the stability of the resource, its commitment to principles of open science and its implementation of relevant community standards and reporting guidelines. A preference is expressed for repositories that issue digital object identifiers (DOIs) through the DataCite system and that share data under the Creative Commons CC0 waiver. Scientific Data currently lists fourteen repositories that focus on specific areas within the Earth and environmental sciences, as well as the broad scope repositories, Dryad and figshare. Readers can browse and filter datasets published at the journal by the host repository using ISA-explorer, a demo tool built by the ISA-tools team at Oxford University1. We believe that well-maintained lists like this one help publishers build a network of trust with community data repositories and provide an important complement to more comprehensive data repository indices and more formal certification efforts.

Full Text Available La course au large en solitaire associe un effort physique et cognitif intense et prolongé durant 10 à 100 jours dans des conditions extrêmes. Elle implique le recours à un sommeil fractionné et des périodes de repos courtes réparties sur l’ensemble du nycthémère. Ces difficultés sont évoquées pour expliquer les incidents, accidents et altérations des performances.Cette étude recense les stratégies mises en œuvre par neuf des meilleurs skippers de la spécialité pour préparer puis gérer ces contraintes au cours d’une course, puis suit un skipper durant une course autour du monde en solitaire et sans escale d’une durée de cent jours.A partir de ces observations, il a été proposé à un skipper expérimenté de tester un agenda interactif de « sommeil » afin d’apprendre à gérer de façon optimale ses périodes de repos durant une course.Ce travail met en évidence que les sujets sont conscients de l’importance de gérer leurs périodes de repos, mais mettent en œuvre peu de stratégies de préparation et de gestion du sommeil avant et durant leur course. Ils présentent une période d’adaptation à ces conditions extrêmes allant de 24 à 72 heures et rencontrent ensuite des périodes de fatigue extrême avec hallucinations. Cette fatigue a des conséquences sur la performance, mais aussi sur l’accidentologie qui apparaît nettement majorée avec un possible délai allant jusqu’à 72h après l’installation d’une dette de sommeil trop importante. Les outils de laboratoire, qui ne pourraient donner des informations intéressantes que sur la base d’une utilisation continue, sont très difficiles à mettre en œuvre ici.Dans ces circonstances, le recours à un agenda de sommeil « interactif », utilisé par le sujet pour comptabiliser et gérer la répartition et la durée de ses périodes de sommeil, semble être une solution individuelle de gestion des alternances veille sommeil.

Monazite-type ceramics for conditioning of minor actinides. Structural characterization and properties

Energy Technology Data Exchange (ETDEWEB)

Babelot, Carole

2013-07-01

The minor actinides (MA) neptunium, americium, and curium are mainly responsible for the long-term radiotoxicity of the High Active Waste (HAW) generated during the nuclear power operation. If these long-lived radionuclides are removed from the HAW by partitioning and converted by neutron fission (transmutation) into shorter-lived or stable elements, the remaining waste loses most of its long-term radiotoxicity. Thus, partitioning and transmutation (P and T) are considered as attractive options for reducing the burden on geological disposals. As an alternative, these separated MA can also be conditioned (P and C strategy) in specifically adapted ceramics to ensure their safe final disposal over long periods. At the moment, spent fuel elements are foreseen either for direct disposal in deep geological repositories or for reprocessing. The highly active liquid waste that is produced during reprocessing is conditioned industrially using a vitrification process before final disposal. Although the widely used borosilicate glasses meet most of the specifications needed, ceramic host matrices appear to be even more suitable in terms of resistance to corrosion. The development of new materials based on tailor-made highly specific ceramics with extremely stable behavior would make it possible to improve the final storage of long-lived high-level radiotoxic waste. In the framework of this PhD research project, monazite-type ceramics were chosen as promising host matrices for the conditioning of trivalent actinides. The focus on the monazite-type ceramics is justified by their properties such as high chemical durability. REPO{sub 4} ceramics are named monazite for RE = La - Gd (monoclinic symmetry) and xenotime for RE = Tb - Lu and Y (tetragonal symmetry). The objective of this study is to contribute to the understanding of the alteration behavior of such ceramics under the repository conditions. REPO{sub 4} (with RE = La, Eu) is prepared by hydrothermal synthesis at 200 C

Congés… pour « prières » Prayers and days off

Full Text Available Les premiers combats de la classe ouvrière se sont portés sur la demande d’une journée de repos, qui par tradition chrétienne a été fixée le dimanche en 1906. Quatre journées de congé à caractère chrétien ont en outre été retenues par le législateur. L’exercice du culte est donc concrètement garanti pour les chrétiens. Avec l’arrivée sur le territoire de la République  de populations de confessions variées, cette organisation du travail apparaît inégalitaire, voire de nature à porter atteinte à la liberté religieuse. Il a été proposé de reconnaître les jours de prières d’autres confessions. Pour l’instant, le législateur n’a pas adopté ces propositions. Mais la question reste posée. Or, la jurisprudence des tribunaux judiciaires et administratifs admet le droit de prier des fidèles des cultes minoritaires, ils peuvent prétendre à un congé lors des fêtes de leur religion dans la mesure où cela n’occasionne pas de perturbation. La consécration de cette jurisprudence souple par le législateur serait de nature à calmer le débat.At the turn of the century, the working classes fought for a day off in the week, which was granted on Sundays by the legislator in 1906. Four additional christian holidays are also legal. So the right to pray is garanteed for christians. As different populations with various faiths settled in France, this organisation has seemed to violate the principle of equality, and religious freedom. There has been a debate on the question whether some of the days of minority religions should also be observed by all the population. But so far, the legislator has not voted any of these proposals. It remains an issue. The French judge has consistently decided that the people of non christian faiths had the right to be granted a day off to pray on these special days, provided it would not cause prejudice to the organisation they work for. It might help to calm the debate if this

L’obectif était de mettre en relief les particularités du cancer de la thyroïde chez l’enfant et l’adolescent, et d’évaluer nos résultats par rapport à la littérature internationale a travers une série de cas la plus représentatif au Maroc: 22 cas. C'est une étude rétrospective descriptive des patients atteints de cancer différencié de la thyroïde, hospitalisés au service d’ORL et de Chirurgie Cervico-faciale de L’hopital 20 Août de Casablanca-Maroc, sur la période qui s’étend de Janvier 1995 à Mars 2015. Nous avons recueilli les données relatives à 22 cas, qui répondaient à nos critères d’inclusion. L’âge moyen de nos patients était de 14 ans, avec une sex-ratio 3,4, la plupart de nos patients ont consulté pour un nodule thyroïdien, associé dans 22,7% des cas à une adénopathie cervicale, et dans 9,1% à des signes de compression. L’ensemble des patients ont bénéficié d’une thyroïdectomie totale, suivie d’un curage ganglionnaire dans 31,82%. Le diagnostic de cancer thyroïdien a reposé sur l’examen anatomopathologique de la pièce opératoire, qui a objectivé un carcinome papillaire dans 95,4% des cas, et un carcinome vésiculaire dans 4,5%. Le traitement par l’iode radioactif 131 a été réalisé dans 100% des cas. Par la suite tous nos patients ont été mis sous hormonothérapie thyroïdienne. Une surveillance étroite et régulière a permis de détecter des métastases ganglionnaires chez 3 patients, et les métastases à distance chez 4 patients. Le cancer différencié de la thyroïde de l’enfant et l’adolescent est une entité rare mais agressive, son traitement se base sur la chirurgie, associée à l’irathérapie donnant un pronostic excellent.

The oxidative enzymes of plant tissues are often dormant or only slightly active during the resting state, becoming active on the injury of the tissue or on separation from the tissue. During food processing this results in an acceleration of the oxidation of the natural substrates and polymerization of the products, which discolour the tissue. Copper oxidases are the principal enzymes involved in catalysing these reactions. The activation of the enzyme also leads to its reaction inactivation. One of the causes of the phenomenon of reaction inactivation is the decrease in the effective concentration of the enzyme, probably by the removal or binding of its metal prosthetic group copper. By using copper- 64, in vitro, it was shown that, in a resting solution, cupric ion can complex and/or exchange with the copper of the enzyme and that, in oxidizing solutions, an additional amount of cupric ion can be complexed. Cu-o-quinone- type complexes have higher formation constants than Cu-p-quinone- type complexes. The amount of cupric ion complexed was decreased, if the ion was added in an oxidizing solution after the initiation of polymerization of the o-quinone type reaction products. The kinetics of the exchange and complexing processes for cupric ions with enzyme and reaction products are discussed mathematically.

Objectif Expliquer la présentation clinique, les observations à l’examen physique, les critères diagnostiques et les options de prise en charge du conflit fémoroacétabulaire (CFA). Sources des données Une recherche documentaire a été effectuée dans PubMed pour trouver des articles pertinents sur la pathogenèse, le diagnostic, le traitement et le pronostic du CFA. Message principal Depuis les dernières années, on reconnaît de plus en plus que le CFA est un précurseur potentiel et une étiologie importante des douleurs à la hanche dans la population adulte et de la coxarthrose idiopathique plus tard dans la vie. Le conflit fémoro-acétabulaire désigne un ensemble d’anomalies morphologiques osseuses de l’articulation de la hanche qui se traduit par un contact anormal durant le mouvement. Le CFA par effet came concerne une proéminence osseuse non sphérique du col fémoral proximal ou de la jonction tête-col. Le CFM par effet tenaille désigne une couverture acétabulaire excessive par-dessus la tête du fémur, qui peut se produire en raison de diverses variantes morphologiques. Les patients qui ont un CFA présentent une douleur inguinale antérieure chronique, profonde ou lancinante, le plus souvent en position assise, durant ou après une activité. Les patients peuvent aussi ressentir des douleurs occasionnelles aiguës durant l’activité. Il faut procéder à une anamnèse approfondie portant notamment sur l’incidence de traumatismes ou la fréquence de l’exercice. Il faut aussi faire un examen physique complet des hanches, de la région lombaire et de l’abdomen pour évaluer d’autres causes de douleurs inguinales antérieures. Le diagnostic de CFA est confirmé par radiographie. Le conflit fémoro-acétabulaire peut être pris en charge selon une approche conservatrice comportant du repos, la modification des activités, des médicaments et de la physiothérapie ou encore être traité par intervention chirurgicale.

The use of the radioactive tracers {sup 24}Na and {sup 42}K, and the electrophysiological fine study carried out on the plant Cephalopods nervous cells have made it possible, during ten years, to study the relationships between the electrical phenomena observed during the propagation of the nervous impulse and the ionic movements which occur at the cell membrane between the intra- and extra-cellular media. In the state of rest, the nerve fibres present a certain permeability towards sodium and potassium, a permeability which allows the renewal, from the extra-cellular medium, of the cations contained in the cytoplasm. At the moment of the passage of the nervous impulse, it is possible to demonstrate a temporary increase in the permeability towards the sodium which causes the entry of Na{sup +} ions into the nerve fibre, whilst, a few milliseconds later, the increase in the potassium permeability causes the departure of an equivalent quantity of K{sup +} ions. A recovery phase follows the passage of the nervous impulse, during which the original ionic conditions are re-established. If the potassium movements can be considered as passive, the expulsion of Na{sup +} requires, on the part of the cell, the use of a part of the metabolic energy. (author) [French] L'utilisation des indicateurs radioactifs {sup 24}Na et {sup 42}K, et l'etude electrophysiologique fine realisee sur des cellules nerveuses geantes de Cephalopodes a permis, depuis une dizaine d'annees, d'etudier les rapports entre les phenomenes electriques observes lors de la propagation de l'influx nerveux et les mouvements ioniques qui s'effectuent au niveau de la membrane cellulaire entre milieux intracellulaire et extracellulaire. A l'etat de repos, les fibres nerveuses possedent pour le sodium et le potassium, une permeabilite qui permet le renouvellement, a partir du milieu extracellulaire des cations contenus dans le cytoplasme. Au moment du passage de l'influx nerveux, on peut mettre en evidence une

Les patients BPCO modérés à sévères montrent d’importantes limitations à l’exercice physique dans leurs activités journalières, affectant de manière significative leur qualité de vie. Il existe plusieurs causes à cette limitation identifiées dans la littérature: les limitations des débits ventilés, l’hyperinflation pulmonaire, la faiblesse des muscles respiratoires et périphériques, parmi d’autres.Le but de cette étude etait d’identifier les facteurs en relation possible avec la limitation de la performance physique chez un groupe de patients BPCO modérés à sévères.Nous avons étudié 24 sujets masculins, âgés de 64,13+8,46 ans (de 46-83 ans, FEV1:46,96+12,99%, FRC: 144,71+26,86%, DLCO: 69,88+16,49 % (% de la valeur prédite, PaO2:78,25+7,82 mmHg, PaCO2:40,78+4,28 mmHg.

Le recueil de données s’est effectué en situation naturelle. Notre méthode a combiné l’observation directe et des entretiens compréhensifs. Les rythmes de travail sont la principale cause de fatigue, car les périodes de repos n’autorisent pas une récupération suffisante. Ainsi, nous notons une accumulation de la fatigue d’ordre psychologique tout au long de la saison de pêche. Cette récupération est limitée par les troubles du sommeil observés à bord. De surcroît, l’analyse de l’activité du patron pêcheur révèle une charge de travail conséquente à la source de stress et de risque dans ce contexte de vigilance minorée.We analyzed the dynamics of the fatigue processes through the activity of pelagic trawlers captains.We focussed on perceived fatigue from a psychological point of view. The data were collected in natural situation. Our methodology combined direct observation with non-directive interviews.The work rhythms aboard trawlers (phases of work and rest alternation are the main cause of the captain’s fatigue. The short periods of rest do not authorize a sufficient recovery. Thus, we note a fatigue accumulation throughout the trawling season. In addition, the recovery is restricted by the sleep disorders observed during the embarkations. The analysis of the trawler captain’s activity reveals workload, causing stress, as well as risk-taking in a diminished vigilance context.Analizamos los procesos de fatiga a traves de la actividad de tres capitanes de pesca de los barcos pescadores pelágicos.

Caractérisation rhéologique et modélisation structurelle des systèmes argile-polymère. Application aux fluides de forage Rheometry and Structural Modelling of Clay-Polymer Systems. Application to Drilling Fluids

Full Text Available Le comportement rhéologique des systèmes argile-polymère couramment utilisés dans les formulations des fluides de forage est examiné dans cet article. Un protocole d'essai adapté à leur nature thixotrope qui permet d'effectuer des mesures reproductibles est mis au point. Les propriétés intrinsèques du matériau sont ainsi déterminées sur toute la gamme de sollicitations : du comportement solide aux faibles déformations au comportement fluide aux taux de déformations intenses. Il est montré que ces systèmes sont caractérisés par des temps de restructuration longs, par des rhéogrammes en régime permanent présentant un minimum de contrainte et par des dépassements importants de la contrainte lors des essais transitoires. Ces effets peuvent être complètement masqués par des procédures d'essai préconisés par les normes en vigueur dans le forage. Une loi de comportement structurelle récente qui relie les propriétés thixotropes et viscoélastiques du matériau aux mécanismes de création et de rupture des flocs peut reproduire l'ensemble des phénomènes observés. Sa capacité de décrire le changement de structure au sein du fluide sous écoulement ou au repos et les variations associées de la contrainte permet d'envisager une meilleure modélisation de l'hydraulique du forage. The rheological behaviour of clay-polymer systems that are currently used in the formulation of drilling fluids was studied. A specific experimental procedure was used to account for thixotropic effects and obtain, thus, reproducible results. In this way it was possible to determine intrinsic properties in the whole range, from solid behaviour below the yield stress to liquid behaviour at very high shear. These systems are shown to be characterised by very long time scales of structure recovery, by the existence of a minimum shear stress in the steady state flow curve and by important stress overshoots in transient flows. These effects can be

Full Text Available Des méthodes de résolution analytiques et numériques ont été proposées, pour déterminer les distributions de contraintes autour de forages pétroliers dans le cas de matériaux peu résistants. Le calcul de ces distributions aboutit à la détermination des pressions de fracturation. Le critère de plasticité de Mohr-Coulomb a été choisi pour la résolution analytique. Cette étude permet d'établir trois schémas types de distribution de contraintes, au moment de la fracturation, pour un régime permanent d'écoulement. La géométrie axisymétrique du modèle a permis d'utiliser une méthode numérique par schéma aux différences finies. La loi de comportement du matériau est déduite du critère de plasticité de Drucker. Cette résolution permet le chargement incrémental en pression dans le forage et de simuler une injection rapide par un couplage simplifié fluide-squelette. Le modèle élastoplastique à deux surfaces de charge de Lade-Shao a finalement été retenu pour décrire l'écrouissage du matériau. La comparaison des résultats des différentes méthodes de calcul s'effectue sur la base de l'influence respective du coefficient de poussée au repos Ko, du coefficient de Poisson et de la résistance à la compression, Co, du matériau. Analytical and numerical methods are proposed, in order to determine stresses distribution around borehole for axisymetric problems in the case of low strengh materials. Calculation of these distributions leads to the determination of hydraulic fracture-pressure. Analytical solutions were found in the case of Mohr-Coulomb criterion and steady flow. These solutions leads to three typical stresses distributions when hydraulic fracture takes place. Because problem's axisymetry, the finite difference method was used. The constitutive law was deduced using Drücker plasticity criterion with an associated flow rule for elastic perfectly plastic behaviour. Such a numerical method can take into

Full Text Available Le manuscrit de Hegel découvert en 1917 et connu comme « le plus ancien programme systématique de l'idéalisme allemand » est considéré comme un texte emblématique pour le processus de genèse de l’idéalisme allemand. Bien qu’il adopte la langue de Kant et la « révolution copernicienne » que ce dernier avait apportée en fondant la philosophie sur le sujet pensant, ce texte formule des questions qui avaient été laissées sans réponse par le kantisme, en demandant qu’elles soient reposées dans le cadre d’un nouveau fondement, systématique, de la philosophie. Le système que trace Hegel culmine avec l’idée suprême, l’idée du Beau, dans laquelle « la Vérité et la Bonté s’allient ». Le sens esthétique est érigé en « instrument » philosophique fondamental, indispensable à l’acte esthétique « suprême » par lequel la Raison conçoit et « englobe toutes les idées ». L’élément esthétique est également nécessaire à la nouvelle Volksreligion proclamée par le projet utopique hégélien. Enfin, en dépit des références kantiennes indubitables, l’ambition profonde du texte reste le dépassement d’un questionnement transcendantal orienté vers la conscience et son remplacement par un désir d’origine romantique de dépassement de toute dichotomie et d’atteindre l’union avec l’absolu.Hegel’s manuscript, which was found in 1917 and became known as “The earlier systematic programme of German idealism”, is considered to be a central text in the birth process of German Idealism. Although it adopts Kant’s language and the “Copernican shift” he introduced through the grounding of philosophy on the thinking subject, this extract raises questions that were left unanswered by Kantianism, with a view of re-positing them in the frame of a new systematic grounding of philosophy. The system sketched by Hegel culminates in the “highest idea” of the beautiful, in which �

accordingly. The admin tool of the 52°North WPS was extended to support automated retrieval and deployment of computational models from GitHub repositories. Once the R code is available in the GitHub repo, the contained process can be easily deployed and executed by simply defining the GitHub repository URL in the WPS admin tool. We illustrate the usage of the approach by sharing and running a model for land use system archetypes developed by the Helmholtz Centre for Environmental Research (UFZ, see Vaclavik et al.). The original R code was extended and published in the 52°North WPS using both, public and non-public datasets (Nüst et al., see also https://github.com/52North/glues-wps). Hosting the analysis in a Git repository now allows WPS administrators, client developers, and modelers to easily work together on new versions or completely new web processes using the powerful GitHub collaboration platform.

Vacas y rebecos muestran claras relaciones entre varios tipos de actividad y los factores ambientales, mientras que la relación es menos aparente para ovejas y cabras. [fr] Nous avons étudié les rythmes d'activité journaliers ainsi que la distribution temporelle des différents types de comportement de quatre ongulés {vaches, brebis, chèvres et isards; ils utilisent la même unité pastorale (estive de Goriz dans les Pyrénées Centrales, au Parc National d'Ordesa. Aussi nous avons evalué l'influence de diverses variables environnenmentales (altitude, pente et recouvrement végétal sur le comportement des rumiants. Le pâturage devient l'activité prépondérante chez toutes les espèces: vaches 58%, brebis 53%, chèvres 55% et isards 68% du temps diurne. Les bovins passent plus de temps que les autres au repos (41% et les brebis dédient beaucoup de leur temps au déplacement (35%. Ces résultats suggèrent une relation inverse le poids vif et le temps du pâturage, phénomène déjà noté par d'autres. Bovins et caprins montrent deus périodes maximales de pâturage: le matin et la tombée du jour, tandis qu'ovins et isards présentent plusieurs pics du pâturage pendant la journée. Enfin bovins et isards montrent des relations significatives entre chacun des différents types de conduite et certains de l'environnement, tandis que ces rapports s'avèrent moins clairs pour les brebis et les caprins.

retard qui s'etablit entre deux particules de masse M appartenant a cette derniere espece est defini par la difference entre les temps qu'elles mettent pour franchir la meme distance. Dans le vide, les retards peuvent atteindre des valeurs quelconques, Mais, lorsque les particules se propagent dans un milieu absorbant, les retards tendent vers une limite bien definie quelles que soient les energies initiales des particules. On demontre que le retard maximum est donne par ({delta}t){sub max} {approx_equal} 0,6 E{sub 0} / cK{sub min}, ou E{sub 0} = Mc{sup 2} represente l'energie au repos de la particule et K{sub min} la perte minimum d'energie par cm de parcours dans le milieu donne. Par exemple, dans le cas des protons traversant differents milieux absorbants, les valeurs de ({delta}t){sub max} pour l'air (TPN), l'eau, l'Al et le Pb sont respectivement egales a 8,3.10{sup -6}, 9,7.10{sup -9}, 45.10{sup -9} et 1,6 10{sup -9} sec. Les valeurs correspondantes de ({delta}t){sub max} pour les electrons, sont de l'ordre de 10{sup -9} sec pour l'air et de l'ordre de 10{sup -12} sec pour les milieux condenses. Il en resulte que, si les particules appartenant a une gerbe manifestaient entre elles des retards superieurs a ceux qui vienent d'etre indiques, le fait constituerait une preuve suffisante de l'existence de particules lourdes au sein de la gerbe. Par ailleurs, la relation qui relie ({delta}t){sub max} a la masse M pourrait servir de base a une methode de spectrographie de masse des particules de grande energie. (auteur)

éalisation d'un nouveau capteur de débit massique basé sur l'effet Peltier. Le capteur en forme de circuit imprimé bimétallique, comporte plusieurs pistes métalliques continues parallèles entre elles et partiellement recouvertes par un grand nombre de dépôts électrolytiques de nature différente. Un tel circuit se comporte comme un circuit thermoélectrique classique dans lequel les parties homogènes non recouvertes par le dépôt électrolytique constituent le premier conducteur du couple, les parties plaquées constituant le second conducteur. La méthode de mesure consiste à faire passer un courant électrique dans une ou plusieurs pistes constituant le circuit émetteur de façon à générer par effet Peltier des gradients thermiques qui seront détectés par un circuit détecteur identique placé à proximité. Dans le cas particulier d'un fluide au repos, la f.e.m. détectée par le circuit détecteur dépend de la conductivité thermique du fluide. Lorsque le fluide est en mouvement relatif par rapport au circuit, il est possible de détecter une f.e.m. dépendant en grandeur et en signe de la vitesse d'écoulement du fluide. A titre d'application un capteur de débit massique a été réalisé en plaçant les circuits thermoélectriques dans une canalisation parcourue par le fluide en mouvement.

shield to enable the installation of cables and tubes for experiments. The irradiation time can be set by means of a separate timer, so that the sources may be taken back into the rest position after irradiation, or they may be taken into the irradiation position after expiration of the time, as desired. The entire plant is automatically controlled and supervised by an interlock system. A system of radiation detectors and mechanical locks secures optimal safety of the plant against accidents. All important aggregates are supplied by a buffered battery so that, even in the case of a voltage breakdown, undisturbed operation is possible. In the case of defects in important parts of the plant, or wanton damage, an alarm system is triggered off- In acute danger this system immediately takes the sources back into their rest position or, if there is no acute danger, brings them up to the scientist to decide whether or not to continue irradiation.

Variations in hydraulic conductivity with scale of measurement during aquifer tests in heterogeneous, porous carbonate rocks

Science.gov (United States)

Schulze-Makuch, Dirk; Cherkauer, Douglas S.

Previous studies have shown that hydraulic conductivity of an aquifer seems to increase as the portion of the aquifer tested increases. To date, such studies have all relied on different methods to determine hydraulic conductivity at each scale of interest, which raises the possibility that the observed increase in hydraulic conductivity is due to the measurement method, not to the scale. This study analyzes hydraulic conductivity with respect to scale during individual aquifer tests in porous, heterogeneous carbonate rocks in southeastern Wisconsin, USA. Results from this study indicate that hydraulic conductivity generally increases during an individual test as the volume of aquifer impacted increases, and the rate of this increase is the same as the rate of increase determined by using different measurement methods. Thus, scale dependence of hydraulic conductivity during single tests does not depend on the method of measurement. This conclusion is supported by 22 of 26 aquifer tests conducted in porous-flow-dominated carbonate units within the aquifer. Instead, scale dependency is probably caused by heterogeneities within the aquifer, a conclusion supported by digital simulation. All of the observed types of hydraulic-conductivity variations with scale during individual aquifer tests can be explained by a conceptual model of a simple heterogeneous aquifer composed of high-conductivity zones within a low-conductivity matrix. Résumé Certaines études ont montré que la conductivité hydraulique d'un aquifère semble augmenter en même temps que la partie testée de l'aquifère s'étend. Jusqu'à présent, ces études ont toutes reposé sur des méthodes de détermination de la conductivité hydraulique différentes pour chaque niveau d'échelle, ce qui a conduit à penser que l'augmentation observée de la conductivité hydraulique pouvait être due aux méthodes de mesure et non à l'effet d'échelle. Cette étude analyse la conductivité hydraulique par

consideration principale dont il faut tenir compte est d'ordre non pas radiologique mais toxicologique, en raison des effets chimiques que produit l'uranium depose dans les reins. Une certaine quantite d'uranium se depose egalement dans le squelette mais, dans le cas de l'uranium naturel, la radioexposition du squelette est moins critique que des effets toxiques sur les reins. Dans le cas de composes solubles de l'uranium fortement enrichi ayant une activite specifique elevee, la consideration principale est d'ordre radiologique; les effets chimiques sur les reins sont moins limitatifs que la radioexposition du squelette, qui devient ainsi l'organe critique. Dans ce cas, il vaut mieux essayer d'evaluer la charge corporelle retenue et non la quantite d'uranium absorbee. On peut y parvenir en analysant des echantillons d'urines prelevees, non pas immediatement apres la contamination, mais apres un certain delaL Les echantillons preleves apres une periode de vacances sont probablement les meilleurs que l'on puisse obtenir en pratique, mais on peut avoir a se contenter d'echantillons preleves apres le repos hebdomadaire qui suit une semaine de travail dans une atmosphere chargee de poussieres d'uranium. (author) [Spanish] La causa mas corriente de contaminacion interna con uranio es la inhalacion de polvo de este elemento. Los compuestos solubles de uranio pasan rapidamente de los pulmones a la sangre y la mayor parte del uranio que penetra en el torrente circulatorio es excretado muy pronto por via urinaria. La cantidad de uranio soluble absorbida en el curso del trabajo se puede calcular a partir del contenido en uranio de muestras de orina tomadas inmediatamente despues del mismo. Los compuestos'solubles de uranio natural se caracterizan por el hecho de que la consideracion primordial no es de orden radiologico sino toxicologico, debido a los efectos quimicos del uranio depositados en los rinones Parte del uranio se deposita tambien en el esqueleto, pero la irradiacion del

miniaturized mass spectrometry. From these arguments we may conclude that a penetration of measuring instruments (penetrators) into the icy surface of Europa just beyond the few millimeters beyond the stopping-depth would be sufficient for an accurate estimate of the delta-34 S parameter. This would be a possible way for rejecting, or supporting, the hypothesis of biogenicity of the Europan sulfur patches. The fact that missions such as LAPLACE, or others, can envisage, and undertake, such measurements (in the foreseeable future) is of the utmost importance for astrobiology's most significant question: Are there other environments in our own Solar System where we could settle the question of habitability, by making use of the available technologies? These results suggest that with the optimum stopping-depth we have calculated, sulfate-reducing bacteria would leave a measurable trace of their activity that is not affected by the harsh external environment. In addition, we have related sulfur transport in microbial mats that are known to take place in the Antarctica subglacial lakes with a mechanism that might rationalize what is taking place in the sulfur patches of the icy surface of Europa. Lake Vostok has given us preliminary hints from microorganisms retrieved from the accreted ice that lies just above its still-unexplored liquid water.

Il a ete demontre qu'un transfert de mineraux s'etait produit entre les liquides extiacellulaire et intracellulaire. En provoquant une paralysie complete ou incomplete par le glucose et l'insuline chez des malades ayant deja subi des attaques de paralysie, on a constate dans cinq cas sur huit que le rapport des concentrations depassait 38,0 pendant chacune des attaques. On a aussi constate que l'augmentation de cette valeur etait liee a la gravite de la paralysie. La pathogenese de la paralysie semble donc due non seulement a une augmentation du potentiel de repos des muscles mais aussi a la difference entre les concentrations intra- et extracellulaites du potassium.
