  1. Failure rate and reliability of the KOMATSU hydraulic excavator in surface limestone mine (United States)

    Harish Kumar N., S.; Choudhary, R. P.; Murthy, Ch. S. N.


    The model with failure rate function of bathtub-shaped is helpful in reliability analysis of any system and particularly in reliability associated privative maintenance. The usual Weibull distribution is, however, not capable to model the complete lifecycle of the any with a bathtub-shaped failure rate function. In this paper, failure rate and reliability analysis of the KOMATSU hydraulic excavator/shovel in surface mine is presented and also to improve the reliability and decrease the failure rate of each subsystem of the shovel based on the preventive maintenance. The model of the bathtub-shaped for shovel can also be seen as a simplification of the Weibull distribution.

  2. Auto Drain Valve Water Separator inside the Unit of Komatsu HD 465-7R (United States)

    Manurung, V. A. T.; Joko W, Y. T.; Poetra, R. I.


    Water separator is a component that separate water from fuel, so the circulating fuel in the fuel system is not contaminated by water. If there is water inside the water separator, it will be carried by into the fuel system and then impacting to the engine performance. It’s such as lowering engine power because the fuel filter is clogged due to the fuel mix with water. Then the real danger is in case of the fuel mixes with the water. It will damage the fuel system components such as blockage of injectors due to corrosion and wear of fuel supply pump. As informed from daily maintenance record data, we have found that the low power engine trouble was caused by the fuel filter that was clogged high enough. Using the fishbone analysis, we got the main problem is there was water in the fuel separator at maximum level and did not discharge. In this condition, it is need optional device to automatically discharge the water from the water separator while maximum level reached, so the operator does not need to drain the water manually. The operator will be warned by buzzing active alarm and flashing caution lamp inside the cabin. By this method, the potential risk of mix up water with fuel would be avoided and the loss of others component failure would be mostly avoided. By using this tool, we can save net quality income around IDR (Indonesia Rupiah) 11,673,519,800.

    Full Text Available The control and maintenance of inventories is a problem common to all enterprises in any sector of a given economy. Two fundamental question that must be answered in controlling the inventory are when to replenish the inventory and how much to order for replenishment. The (Q,r inventory models attempt to answer the two question under a variety of circumstances. Studies have shown, (1 that a company that ignores lead-time demand variability may suffer great financial damage, (2 that the gamma distribution provides the most common best fit to lead-time demand for variety of inventories items, (3 that a fixed lead-time demand assumption or a normal approximation to it will often yield significant errors (Namit and Chen, 1998.This research performed an efficient and accurate algorithm for solving (Q,r inventory model with gamma lead-time demand.

  11. Physical soil properties and slope treatments effects on hydraulic excavator productivity for forest road construction. (United States)

    Parsakho, Aidin; Hosseini, Seyed Ataollah; Jalilvand, Hamid; Lotfalian, Majid


    Effects of moisture, porosity and soil bulk density properties, grubbing time and terrain side slopes on pc 220 komatsu hydraulic excavator productivity were investigated in Miana forests road construction project which located in the northern forest of Iran. Soil moisture and porosity determined by samples were taken from undisturbed soil. The elements of daily works were measured with a digital stop watch and video camera in 14 observations (days). The road length and cross section profiles after each 20 m were selected to estimate earthworks volume. Results showed that the mean production rates for the pc 220 komatsu excavators were 60.13 m3 h(-1) and earthwork 14.76 m h(-1) when the mean depth of excavation or cutting was 4.27 m3 m(-1), respectively. There was no significant effects (p = 0.5288) from the slope classes' treatments on productivity, whereas grubbing time, soil moisture, bulk density and porosity had significantly affected on excavator earthworks volume (p < 0.0001). Clear difference was showed between the earthwork length by slope classes (p = 0.0060). Grubbing time (p = 0.2180), soil moisture (p = 0.1622), bulk density (p = 0.2490) and porosity (p = 0.2159) had no significant effect on the excavator earthworks length.

    Kita, H.; Miyaji, T.


    Recently, as the CO2 laser oscillator requires bigger power output, steel plates to be cut with a laser cutting machine have become thick plates with thickness of 12mm or more and the size of the plate which can be cut has become from the standard size of 4 inch by 8 inch or 5 inch by 10 inch to a big size of more than several meters because of introduction of the gantry type. In this article, the CO2 laser cutting machine introduced to Komatsu Shearing Co. and its operating conditions are introduced and the trends of powerful laser cutting machines in the cutting industry in the future are predicted. Laser cutting makes high cutting quality, but its device and running costs becomes high. For adopting a laser cutting machine, such items have been individually examined that no bitter work is involved in cutting, no skill is needed, no strain is formed during the press work in the succeeding process and the yield is high (95%), and a Komatsu laser cutting machine has been introduced. As a result, it has been found that the machine can produce a product of higher quality than shearing. Hereafter, this machine will further be used for manufacturing parts of construction machines, etc. for which high accuracy and high quality are demanded. 7 figs., 8 tabs.

Methods: This was a prospective, non-randomized, observational, comparative cohort study in which Trabectome surgery was used alone in patients with POAG or EXG. Trabectome surgery was considered to have failed when at least one of the following three criteria was fulfilled: intraocular pressure (IOP ≥21 mmHg and a <20% reduction below the baseline IOP on two consecutive follow-up visits 3 months or more after surgery; need for additional glaucoma surgery; and an increase in number of medications compared with baseline. Results: The subjects were 32 males (34 eyes and 46 females (48 eyes. POAG was observed in 43 eyes and EXG in 39 eyes. IOP after Trabectome surgery decreased significantly from 22.3±6.8 mmHg at baseline to 14.0±3.9 mmHg (23.0% reduction at month 24 in all cases (P<0.0000. The success rate at 2 years was 51.2% for all cases (POAG, 50.9%; EXG, 49.2%. There was no significant difference in success rate between POAG and EXG (P=0.91. Preoperative IOP (P=0.033 and number of medications (P=0.041 were significant factors for surgical success/failure in multivariate logistic regression. No serious complications were observed. Conclusion: Trabectome surgery achieved favorable IOP control and was equally effective in patients with POAG and those with EXG. Its effects were influenced by preoperative IOP and number of preoperative medications. Keywords: Trabectome, primary open-angle glaucoma, exfoliation glaucoma, success rate, risk factors 

  14. A study of atom zigzag chains on the surface of tungsten

    International Nuclear Information System (INIS)

    Audiffren, M.; Traimond, P.; Bardon, J.; Drechsler, M.


    Nishigaki and Nakamura have observed zigzag chains on the central (011) face of tungsten after field evaporation at T > 140 K. In this paper, a study of the formation, disappearance and structure of such chains is described. Tungsten tips of small radii down to 60 A were used. Chains of 3 to 9 spots, that are clearly visible, are found even at 90 K. Four different structure models of the zigzag chains are discussed, including the multibranch model proposed by the japanese authors. The interpretation of the experimental results shows fairly clearly that the real zigzag chain structure is a special non-dense structure. It must be formed by a local displacement of the tungsten adatoms in the field. Without the field, a zigzag chain is transformed into a two-dimensional cluster of the nearest neighbour atom by a small increase in temperature. If the field is reintroduced, the cluster can revert to the initial zigzag structure. The zigzag structure is interpreted as being caused by forces of repulsion between the atom dipoles. (Auth.)

    Stambaugh, Ronald


    I am very pleased to join the outstanding leadership team for the journal Nuclear Fusion as Scientific Editor. The journal's high position in the field of fusion energy research derives in no small measure from the efforts of the IAEA team in Vienna, the production and marketing of IOP Publishing, the Board of Editors led by its chairman Mitsuru Kikuchi, the Associate Editor for Inertial Confinement Max Tabak and the outgoing Scientific Editor, Paul Thomas. During Paul's five year tenure submissions have grown by over 40%. The usage of the electronic journal has grown year by year with about 300 000 full text downloads of Nuclear Fusion articles in 2011, an impressive figure due in part to the launch of the full 50 year archive. High quality has been maintained while times for peer review and publishing have been reduced and the journal achieved some of the highest impact factors ever (as high as 4.27). The journal has contributed greatly to building the international scientific basis for fusion. I was privileged to serve from 2003 to 2010 as chairman of the Coordinating Committee for the International Tokamak Physics Activity (ITPA) which published in Nuclear Fusion the first ITER Physics Basis (1999) and its later update (2007). The scientific basis that has been developed to date for fusion has led to the construction of major facilities to demonstrate the production of power-plant relevant levels of fusion reactions. We look forward to the journal continuing to play a key role in the international effort toward fusion energy as these exciting major facilities and the various approaches to fusion continue to be developed. It is clear that Nuclear Fusion maintains its position in the field because of the perceived high quality of the submissions, the refereeing and the editorial processes, and the availability and utility of the online journal. The creation of the Nuclear Fusion Prize, led by the Board of Editors chairman Mitsuru Kikuchi, for the most outstanding

  17. Probing primordial non Gaussianity in the BOOMERanG CMB maps: an analysis based on analytical Minkowski functionals

    Migliaccio, M.; Natoli, P.; De Troia, G.; Hikage, C.; Komatsu, E.; Ade, P.A.R.; Bock, J.J.; Bond, J.R.; Borrill, J.; Boscaleri, A.; Contaldi, C.R.; Crill, B.P.; Bernardis, P. de; Gasperis, G. de; Oliveira-Costa, A. de; Di Stefano, G.; Hivon, E.; Kisner, T.S.; Jones, W.C.; Lange, A.E.


    Minkowski functionals are a powerful tool to constrain the Gaussianity of the Cosmic Microwave Background (CMB). In the limit of a weakly non Gaussian field, a perturbative approach can be derived [Hikage C., Komatsu E., and Matsubara T., 2006, ApJ, 653, 11] that is completely based on analytical formulae without requiring computationally intensive, dedicated Monte Carlo non Gaussian simulations of the CMB anisotropy. We apply this machinery to an intensity map derived from the 1998 and 2003 flights of BOOMERanG, analyzed here together for the first time. We set limits on the non-linear coupling parameter f NL as -1020 NL <390 at 95% CL, markedly improving the previous constraints set by [De Troia G. et al., 2007, ApJ, 670, L73] whose analysis was limited to the BOOMERanG 2003 dataset. These limits are the most stringent ever set among suborbital experiments.

  19. Three-point functions in N=4 SYM: the hexagon proposal at three loops

    Basso, Komatsu and Vieira recently proposed an all-loop framework for the computation of three-point functions of single-trace operators of N=4 super-Yang-Mills, the “hexagon program”. This proposal results in several remarkable predictions, including the three-point function of two protected operators with an unprotected one in the SU(2) and SL(2) sectors. Such predictions consist of an “asymptotic” part — similar in spirit to the asymptotic Bethe Ansatz of Beisert and Staudacher for two-point functions — as well as additional finite-size “wrapping” Lüscher-like corrections. The focus of this paper is on such wrapping corrections, which we compute at three-loops in the SL(2) sector. The resulting structure constants perfectly match the ones obtained in the literature from four-point correlators of protected operators.

  2. Comparing models of rapidly rotating relativistic stars constructed by two numerical methods (United States)

    Stergioulas, Nikolaos; Friedman, John L.


    We present the first direct comparison of codes based on two different numerical methods for constructing rapidly rotating relativistic stars. A code based on the Komatsu-Eriguchi-Hachisu (KEH) method (Komatsu et al. 1989), written by Stergioulas, is compared to the Butterworth-Ipser code (BI), as modified by Friedman, Ipser, & Parker. We compare models obtained by each method and evaluate the accuracy and efficiency of the two codes. The agreement is surprisingly good, and error bars in the published numbers for maximum frequencies based on BI are dominated not by the code inaccuracy but by the number of models used to approximate a continuous sequence of stars. The BI code is faster per iteration, and it converges more rapidly at low density, while KEH converges more rapidly at high density; KEH also converges in regions where BI does not, allowing one to compute some models unstable against collapse that are inaccessible to the BI code. A relatively large discrepancy recently reported (Eriguchi et al. 1994) for models based on Friedman-Pandharipande equation of state is found to arise from the use of two different versions of the equation of state. For two representative equations of state, the two-dimensional space of equilibrium configurations is displayed as a surface in a three-dimensional space of angular momentum, mass, and central density. We find, for a given equation of state, that equilibrium models with maximum values of mass, baryon mass, and angular momentum are (generically) either all unstable to collapse or are all stable. In the first case, the stable model with maximum angular velocity is also the model with maximum mass, baryon mass, and angular momentum. In the second case, the stable models with maximum values of these quantities are all distinct. Our implementation of the KEH method will be available as a public domain program for interested users.

  3. [Association between Hajime Hoshi and Imperial princes]. (United States)

    Misawa, Miwa


    Hajime Hoshi established Hoshi Pharmaceutical Company in 1911, and developed it into the No. 1 pharmaceutical company of Japan by 1918. He had many well-known friends and acqaintances including Hirobumi Ito, Shinpei Goto, Koki Hirota, Hideyo Noguchi, Inazo Nitobe, Kojiro Matsushita and Mitsuru Toyama. In this paper, the Imperial Family (princes) who had personal relationships with Hajime Hoshi are reported. Six princes visited the factories of Hoshi Pharmaceutical Company and Hoshi Pharmaceutical Commercial School from 1922 to 1928. They were Princes Fushimino-miya, Asakano-miya, Chichibuno-miya, Kitashirakawano-miya, Takedano-miya and LiKen-Ko. Each of His Imperial Highnesses showed much enthusiasm when visiting the factories and school. They wished to see the latest world-scale modern factories that were producing important drugs and exporting them to advanced Western countries. The anniversary date of the founding of Hoshi University is May 18, the day on which Fushmino-miya visited the former school of the University. Hajime Hoshi named his daughter Yasuko after Prince Asakano-miya Yasuhiko. He used to receive invitations to visit from those princes, hold congenial talks with them, and was sometimes presented with Imperial gifts. Hoshi had a global view and warm character, and entertained a deep respect for the Imperial Family. Therefore, it is conjectured that the princes had a favorable impression for Hoshi. It is believed that the splendid historical association between Hajime Hoshi and the Imperial princes should be recorded as historical events.

Plasma ET-1 concentrations were determined using a commercially available enzyme-linked immunosorbent assay kit.Results: Mean plasma ET-1 levels of RP patients (1.88 ± 0.56 pg/mL were significantly lower than those of control subjects (2.30 ± 0.30 pg/mL, Mann-Whitney’s U test; P < 0.01. However, ET-1 concentrations varied markedly in each patient. Among RP patients, a significant correlation of ET-1 concentrations was not observed in terms of its hereditary forms or other clinical factors.Conclusion: ET-1 may be important in the pathogenesis of RP, and measurement of its plasma concentrations may also contribute to additional insights into the retinal hemodynamics of RP.Keywords: endothelin-1, retinitis pigmentosa, retinal hemodynamics

All cases underwent successful phacovitrectomy with ILM peeling for a thin ERM. The optical coherence tomography (OCT images were examined before and after the surgery. The changes in the average foveal (1 mm thickness and the foveal areas within 500 µm from the foveal center were measured. The postoperative changes in the inner and outer retinal areas determined from the cross-sectional OCT images were analyzed.Results: The average foveal thickness and the inner and outer foveal areas increased significantly after the surgery in each of the three cases. The percentage increase in the average foveal thickness relative to the baseline thickness was 26% in Case 1, 29% in Case 2, and 31% in Case 3. The percentage increase in the foveal inner retinal area was 71% in Case 1, 113% in Case 2, and 110% in Case 3, and the percentage increase in foveal outer retinal area was 8% in Case 1, 13% in Case 2, and 18% in Case 3.Conclusion: The increase in the average foveal thickness and the inner and outer foveal areas suggests that a centripetal movement of the inner and outer retinal layers toward the foveal center probably occurred due to the ILM peeling.

  6. WMAP five-year constraints on lepton asymmetry and radiation energy density: implications for Planck

    International Nuclear Information System (INIS)

    Popa, L A; Vasile, A


    In this paper we set bounds on the radiation content of the Universe and neutrino properties by using the WMAP (Wilkinson microwave anisotropy probe) five-year CMB (cosmic microwave background) measurements complemented with most of the existing CMB and LSS (large scale structure) data (WMAP5+All), imposing also self-consistent BBN (big bang nucleosynthesis) constraints on the primordial helium abundance. We consider lepton asymmetric cosmological models parametrized by the neutrino degeneracy parameter ξ ν and the variation of the relativistic degrees of freedom, ΔN eff oth , due to possible other physical processes occurring between BBN and structure formation epochs. We get a mean value of the effective number of relativistic neutrino species of N eff = 2.98  2.27 3.60   1.65 4.37 , providing an important improvement over the similar result obtained from WMAP5+BAO+SN+HST (BAO: baryonic acoustic oscillations; SN: supernovae; HST: Hubble Space Telescope) data (Komatsu et al (WMAP Collaboration), 2008 Astrophys. J. Suppl. submitted [0803.0547]). We also find a strong correlation between Ω m h 2 and z eq , showing that we observe N eff mainly via the effect of z eq , rather than via neutrino anisotropic stress as claimed by the WMAP team (Komatsu et al (WMAP Collaboration), 2008 Astrophys. J. Suppl. submitted [0803.0547]). WMAP5+All data provide a strong bound on the helium mass fraction of Y p = 0.2486 ± 0.0085 (68% CL), that rivals the bound on Y p obtained from the conservative analysis of the present data on helium abundance. For the neutrino degeneracy parameter we find a bound of −0.216≤ξ ν ≤0.226 (68% CL), which represents an important improvement over the similar result obtained by using the WMAP three-year data. The inclusion in the analysis of LSS data reduces the upper limit of the neutrino mass to m ν ν and Y p down to σ(ξ ν )≅0.089 (68% CL) and σ(Y p ) = 0.013 (68% CL) respectively, values fully consistent with the BBN bounds on

    International Nuclear Information System (INIS)


    The International Atomic Energy Agency (IAEA) and the Government of Japan signed an agreement today aimed at enhancing nuclear security measures for the summer Olympic Games and Paralympic Games in Tokyo in 2020. The agreement follows previous IAEA support to major public events, including the 2016 Olympic Games in Rio de Janeiro and the 2012 European soccer championship in Poland and Ukraine. IAEA Director General Yukiya Amano and Japanese Foreign Minister Taro Kono presided over the signing ceremony at the Agency’s headquarters in Vienna. Practical Arrangements outlining the planned cooperation were signed by IAEA Deputy Director General Juan Carlos Lentijo, head of the Department of Nuclear Safety and Security, and H.E. Mitsuru Kitano, Japan’s Ambassador to the International Organizations in Vienna. “The IAEA has extensive experience in supporting Member States on nuclear security for major public events,” Amano said at the ceremony. “The Agency welcomes the cooperation to support the Olympic and Paralympic Games in Tokyo, and is already cooperating with Japan by sharing the experiences of Member States which previously hosted the Olympics.” The details of the cooperation will be decided in due course, but the possible areas of cooperation include the IAEA offering Japanese authorities training courses, workshops, technical visits and exercises related to nuclear security, hosting preparatory technical meetings and lending supplementary radiation detection equipment. The IAEA and Japan may also exchange information related to nuclear security events as appropriate and through the cooperation, the IAEA will also benefit from Japan’s good practices on nuclear security.

Other roles of FGF23 have recently been reported, such as commitment to myocardium enlargement and immunological roles in the spleen. In this study, we aimed to identify the roles of FGF23 in the kidneys other than calcium–phosphorus metabolism. Methods: DNA microarrays and bioinformatics tools were used to analyze gene expression in mIMCD3 mouse renal tubule cells following treatment with FGF23, erythropoietin and/or an inhibitor of ERK. Results: Three protein-coding genes were upregulated and 12 were downregulated in response to FGF23. Following bioinformatics analysis of these genes, PPARγ and STAT3 were identified as candidate transcript factors for mediating their upregulation, and STAT1 as a candidate for mediating their downregulation. Because STAT1 and STAT3 also mediate erythropoietin signaling, we investigated whether FGF23 and erythropoietin might show interactive effects in these cells. Of the 15 genes regulated by FGF23, 11 were upregulated by erythropoietin; 10 of these were downregulated following cotreatment with FGF23. Inhibition of ERK, an intracellular mediator of FGF23, reversed the effects of FGF23. However, FGF23 did not influence STAT1 phosphorylation, suggesting that it impinges on erythropoietin signaling through other mechanisms. Conclusion: Our results suggest cross talk between erythropoietin and FGF23 signaling in the regulation of renal epithelial cells. Keywords: FGF23, STAT1, PPARγ, DNA microarray

  9. Terrain Interaction With The Quarter Scale Beam Walker (United States)

    Chun, Wendell H.; Price, R. S.; Spiessbach, Andrew J.


    Frame walkers are a class of mobile robots that are robust and capable mobility platforms. Variations of the frame walker robot are in commercial use today. Komatsu Ltd. of Japan developed the Remotely Controlled Underwater Surveyor (ReCUS) and Normed Shipyards of France developed the Marine Robot (RM3). Both applications of the frame walker concept satisfied robotic mobility requirements that could not be met by a wheeled or tracked design. One vehicle design concept that falls within this class of mobile robots is the walking beam. A one-quarter scale prototype of the walking beam was built by Martin Marietta to evaluate the potential merits of utilizing the vehicle as a planetary rover. The initial phase of prototype rover testing was structured to evaluate the mobility performance aspects of the vehicle. Performance parameters such as vehicle power, speed, and attitude control were evaluated as a function of the environment in which the prototype vehicle was tested. Subsequent testing phases will address the integrated performance of the vehicle and a local navigation system.

    Critical Tests of Theory of the Early Universe using the Cosmic Microwave Background, by Prof. Eiichiro Komatsu, Max-Planck-Institut für Astrophysik, Garching, (Germany). Monday 25 February 2013 at 17:00 École de Physique, Auditoire Stueckelberg 24, quai Ernest-Ansermet, 1211 Genève 4 Abstract: The Cosmic Microwave Background (CMB), the fossil light of the Big Bang, is the oldest light that one can ever hope to observe in our Universe. The CMB provides us with a direct image of the Universe when it was still an "infant" - 380,000 years old. The Wilkinson Microwave Anisotropy Probe (WMAP) has mapped the microwave sky in five frequency bands for nine years since 2001, creating a full-sky CMB map with the unprecedented precision. The WMAP data have enabled us to obtain a wealth of cosmological information, such as the composition, age, geometry, and history of the Universe. Yet, can we go further and learn about the primordial universe, when it was much younge...

    Full Text Available The present study aimed to carry through the evaluation of costs of two models of harvester in the wood harvesting of Eucalyptus wood. The research evaluated the 6-year old tree fallen and processing, in the cut-to-length system for two models of harvester, in areas located in the cities of Conceição da Barra,Espírito Santo state and Caravelas, Bahia state. It was evaluated the models of harvester PC-228 SHO and PC-200 LC, of the Komatsu Mark. The information was collected during a period of 6 months, from March to August 2010, by the method of census. It was calculated the operational costs of the two models of harvester , for the countable method, which uses values in ‘Reais’, the Brazilian currency. It was conducted further analysis of cost sensitivity for the elements that contribute most to the final cost. We obtained the operating cost models for PC 200 and PC 228 of R$ 156,95 and R$ 168,84 per effective hour, respectively. In relation with the total operational costs, the most significant costs were: fuel, maintenance, and repairs/ depreciation, with 24.41%, 22.39% and 19.08%, respectively. In the sensitivity analysis, simulating a situation where the company gets a real economy of 10% in each one of these items, the same one will be able to get a reduction in the cost of production in 7%, for the two evaluated machines.

    The effect of fin attachment on the thermal stress reduction of exhaust manifold of an off road diesel engine(Komatsu HD325-6) was investigated.For doing this,coupled thermo-fluid-solid analysis of exhaust manifold of the off road diesel engine was carried out.The thermal analysis,including thermal flow,thermal stress,and the thermal deformation of the manifold was investigated.The flow inside the manifold was simulated and then its properties including velocity,pressure,and temperature were obtained.The flow properties were transferred to the solid model and then the thermal stresses and the thermal deformations of the manifold under different operating conditions were calculated.Finally,based on the predicted thermal stresses and thermal deformations of the manifold body shell,two fin types as well as body shell thickness increase were applied in the critical induced thermal stress area of the manifold to reduce the thermal stress and thermal deformation.The results of the above modifications show that the combined modifications,i.e.the thickness increase and the fin attachment,decrease the thermal stresses by up to 28% and the contribution of the fin attachment in this reduction is much higher compared to the shell thickness increase.

  15. Autopoiesis, Observation and Informatics: Lessons from the Development of Autopoietic Systems Theory in Japan

    Directory of Open Access Journals (Sweden)

    Wataru Hashimoto


    Full Text Available This article is concerned with redefining the notion of information from a perspective of systems theory. In recent years, the notion of information, which was closely related to the framework of old cybernetics, has been refined in parallel with the emergence of new cybernetics, especially second-order cybernetics and autopoiesis. The systemic view of new cybernetics provides us with the notion of “informationally closed system.” This notion is congruent with the epistemological implications of radical constructivism. In order to help understand this argument, we aim at highlighting the development of autopoietic systems theory in Japan. Autopoiesis has often been considered as a thoroughly closed system in Japan, where the relationships between autopoiesis and radical constructivism have frequently been overlooked. This is mainly because the importance which autopoietic systems theory originally attaches to the notion of observer and observation has been inadequately discussed, and autopoietic systems theory is regarded as distinct from second-order cybernetics and radical constructivism. However, they must be dealt with together, and Humberto Maturana should be given credit for his ontology of observing. Since the publication of his paper “Biology of Cognition,” Maturana has been attempting to explain the notion of observation as a biological phenomenon in his own way. Likewise, by taking into consideration the notion of observation, we can build a unified theory of information. Fundamental Informatics, which is being developed by Toru Nishigaki, outlines a unified approach to information by putting human observers at the center of his theory. Social and mechanical information is generated only when human observers conduct observations on the basis of biological information, and this mechanism of generation of information is discussed through the notion of “hierarchical autonomous system.” For an autopoietic organi- zation to be

We implemented a pilot intervention with a prospective and longitudinal design in a regional city. This study evaluates the usefulness of the COPD taskforce and intervention based on COPD case detection rate and per capita medical costs.Method: We distributed a questionnaire to all 8,878 inhabitants aged 50–89 years, resident in Matsuura, Nagasaki Prefecture in 2006. Potentially COPD-positive persons received a pulmonary function test and diagnosis. We implemented ongoing detection, examination, education, and treatment interventions, performed follow-up examinations or respiratory lessons yearly, and supported the health maintenance of each patient. We compared COPD medical costs in Matsuura and in the rest of Nagasaki Prefecture using data from 2004 to 2013 recorded by the association of Nagasaki National Health Insurance Organization, assessing 10-year means and annual change.Results: As of 2014, 256 people have received a definitive diagnosis of COPD; representing 31% of the estimated total number of COPD patients. Of the cases detected, 87.5% were mild or moderate in severity. COPD medical costs per patient in Matsuura were significantly lower than the rest of Nagasaki Prefecture, as was rate of increase in cost over time.Conclusion: The COPD program in Matsuura enabled early detection and treatment of COPD patients and helped to lower the associated burden of medical costs.

  17. Design requirements for innovative homogeneous reactor, lesson learned from Fukushima accident (United States)

    Arbie, Bakri; Pinem, Suryan; Sembiring, Tagor; Subki, Iyos


    The Fukushima disaster is the largest nuclear accident since the 1986 Chernobyl disaster, but it is more complex as multiple reactors and spent fuel pools are involved. The severity of the nuclear accident is rated 7 in the International Nuclear Events Scale. Expert said that "Fukushima is the biggest industrial catastrophe in the history of mankind". According to Mitsuru Obe, in The Wall Street Journal, May 16th of 2011, TEPCO estimates the nuclear fuel was exposed to the air less than five hours after the earthquake struck. Fuel rods melted away rapidly as the temperatures inside the core reached 2800 C within six hours. In less than 16 hours, the reactor core melted and dropped to the bottom of the pressure vessel. The information should be evaluated in detail. In Germany several nuclear power plant were shutdown, Italy postponed it's nuclear power program and China reviewed their nuclear power program. Different news come from Britain, in October 11, 2011, the Safety Committee said all clear for nuclear power in Britain, because there are no risk of strong earthquake and tsunami in the region. Due to this severe fact, many nuclear scientists and engineer from all over the world are looking for a new approach, such as homogeneous reactor which was developed in Oak Ridge National Laboratory in 1960-ies, during Dr. Alvin Weinberg tenure as the Director of ORNL. The paper will describe the design requirement that will be used as the basis for innovative homogeneous reactor. Innovative Homogeneous Reactor is expected to reduce core melt by two decades (4), since the fuel is intermix homogeneously with coolant and secondly we eliminate the used fuel rod which need to be cooled for a long period of time. In order to be successful for its implementation of the innovative system, testing and validation, three phases of development will be introduced. The first phase is Low Level Goals is really the proof of concept;the Medium Level Goal is Technical Goalsand the High

  18. Dual Level Digital Watermarking for Images (United States)

    Singh, V. K.; Singh, A. K.


    More than 700 years ago, watermarks were used in Italy to indicate the paper brand and the mill that produced it. By the 18th century watermarks began to be used as anti counterfeiting measures on money and other documents.The term watermark was introduced near the end of the 18th century. It was probably given because the marks resemble the effects of water on paper. The first example of a technology similar to digital watermarking is a patent filed in 1954 by Emil Hembrooke for identifying music works. In 1988, Komatsu and Tominaga appear to be the first to use the term "digital watermarking". Consider the following hypothetical situations. You go to a shop, buy some goods and at the counter you are given a currency note you have never come across before. How do you verify that it is not counterfeit? Or say you go to a stationery shop and ask for a ream of bond paper. How do you verify that you have actually been given what you asked for? How does a philatelist verify the authenticity of a stamp? In all these cases, the watermark is used to authenticate. Watermarks have been in existence almost from the time paper has been in use. The impression created by the mesh moulds on the slurry of fibre and water remains on the paper. It serves to identify the manufacturer and thus authenticate the product without actually degrading the aesthetics and utility of the stock. It also makes forgery significantly tougher. Even today, important government and legal documents are watermarked. But what is watermarking, when it comes to digital data? Information is no longer present on a physical material but is represented as a series of zeros and ones. Duplication of information is achieved easily by just reproducing that combination of zeros and ones. How then can one protect ownership rights and authenticate data? The digital watermark is the same as that of conventional watermarks.

To study episodic memory in OCD patients, we examined the directed forgetting effect. Patients with OCD and healthy control participants were given a list of 24 emotionally neutral everyday words (12 remember [R]-cued words and 12 forget [F]-cued words under two conditions: List and Item. The results of our study showed that OCD patients recalled a number of F-cued words similar to that for controls and relatively fewer R-cued words than controls under both List and Item conditions. Consequently, the directed forgetting effect was smaller in OCD patients than controls. Our results demonstrated that both selective encoding and retrieval inhibition processes are impaired in OCD, and we suggest that recall of unfavorable items to be forgotten intruded into necessary items to be remembered. This impairment in episodic memory may partially account for some of the unique clinical symptoms of OCD.Keywords: episodic memory, retrieval inhibition, selective encoding

  20. Gitai go: the art of deepening everyday life through exceeding codes. (United States)

    Traversa, Rosa


    The present commentary is focused on exploring holistic ways to approach sense-making processes by following the usage of specific Japanese mimic words, Gitai go, and describing how its functioning cannot be disengaged from an embodied lens to approach language-in-use. In fact, according to Komatsu's (2010) discussion about the extension of meaning derived from Gitai go and its intrinsic flexible characteristics, it is possible--in terms of semiotics--to inquire into vaguely coded systems of mutual understanding, trying to make sense of the general functioning of signs through their peculiar ambiguity as well as their potential to evoke a vivid negotiation of meaning. This seems to show the openness of meaning highlighted by Gitai go, as it is to be referred to the logic of multiplicity deeply linked with the actors' feelings in the setting that could in general terms be labeled as the carnal knowledge. Furthermore, it has been arguing about the complexity of daily life experience and its close relation to a concept of "ordinary art", as the active involvement people show in imagining, changing and creating their personal experience of the world is always performed in their day-by-day frameworks, deeply suggesting a unique strive for appropriating-negotiating-contesting networks of meanings. And this is to be approached as an artistic mode of experiencing, since art too is just embedded in this ever-emerging ambivalence coming from the complex we call "ordinary life" and relating to our deep feelings of facing our futures. Along these lines I suggest that a particular role exists in communicative messages for what is labeled as "redundant" or "superfluous"--since the ambivalence of those messages explicates the dialogical frame of sense-making, in everyday life as a concept of art.

The local control rate was compared between the two groups using the Kaplan–Meier estimator and the log-rank test. Factors affecting local tumor recurrence were analyzed using multivariate logistic regression analysis. Treatment-related toxicity was evaluated using the Common Terminology Criteria for Adverse Events.Results: The local control rates at 6 months and 1 year were 87% and 65% for the miriplatin plus low-dose epirubicin group, and 61% and 43% for the miriplatin group, respectively. Local tumor control rates were significantly better in the miriplatin plus low-dose epirubicin group than in the miriplatin group (P = 0.038. Multivariate analysis showed that the addition of epirubicin was an independent factor associated with better local tumor control (hazard ratio 0.2, P = 0.001. Overall incidence rates for adverse events were not significantly different between the two groups.Conclusion: Additional usage of low-dose epirubicin for TACE using miriplatin improved local tumor control of hepatocellular carcinoma with adverse effects comparable to those observed with TACE using miriplatin alone.Keywords: combination therapy, local recurrence, liver, embolization, comparative study

    We test general relativity (GR) using current cosmological data: the CMB from WMAP5 [E. Komatsu et al. (WMAP Collaboration), Astrophys. J. Suppl. Ser. 180, 330 (2009)], the integrated Sachs-Wolfe (ISW) effect from the cross correlation of the CMB with six galaxy catalogs [T. Giannantonio et al., Phys. Rev. D 77, 123520 (2008)], a compilation of supernovae (SNe) type Ia including the latest Sloan Digital Sky Survey SNe [R. Kessler et al., Astrophys. J. Suppl. Ser. 185, 32 (2009).], and part of the weak lensing (WL) data from the Canada-Franco-Hawaii Telescope Legacy Survey [L. Fu et al., Astron. Astrophys. 479, 9 (2008); M. Kilbinger et al., Astron. Astrophys. 497, 677 (2009).] that probe linear and mildly nonlinear scales. We first test a model in which the effective Newtonian constant μ and the ratio of the two gravitational potentials, η, transit from the GR value to another constant at late times; in this case, we find that GR is fully consistent with the combined data. The strongest constraint comes from the ISW effect which would arise from this gravitational transition; the observed ISW signal imposes a tight constraint on a combination of μ and η that characterizes the lensing potential. Next, we consider four pixels in time and space for each function μ and η, and perform a principal component analysis, finding that seven of the resulting eight eigenmodes are consistent with GR within the errors. Only one eigenmode shows a 2σ deviation from the GR prediction, which is likely to be due to a systematic effect. However, the detection of such a deviation demonstrates the power of our time- and scale-dependent principal component analysis methodology when combining observations of structure formation and expansion history to test GR.

  4. Continued monitoring of aeolian activity within Herschel Crater, Mars (United States)

    Cardinale, Marco; Pozzobon, Riccardo; Michaels, Timothy; Bourke, Mary C.; Okubo, Chris H.; Chiara Tangari, Anna; Marinangeli, Lucia


    In this work, we study a dark dune field on the western side of Herschel crater, a 300 km diameter impact basin located near the Martian equator (14.4°S, 130°E), where the ripple and dune motion reflects the actual atmospheric wind conditions. We develop an integrated analysis using (1) automated ripple mapping that yields ripple orientations and evaluates the spatial variation of actual atmospheric wind conditions within the dunes, (2) an optical cross-correlation that allows us to quantify an average ripple migration rate of 0.42 m per Mars year, and (3) mesoscale climate modeling with which we compare the observed aeolian changes with modeled wind stresses and directions. Our observations are consistent with previous work [1] [2] that detected aeolian activity in the western part of the crater. It also demonstrates that not only are the westerly Herschel dunes movable, but that predominant winds from the north are able to keep the ripples and dunes active within most (if not all) of Herschel crater in the current atmospheric conditions.

    Since the first successful replantation of a human thumb reported by Komatsu and Tamai in 1968, thousands of severed digits and body parts have been successfully salvaged. Restoration of anatomic form and function are the goals of replantation after traumatic tissue amputation. Regardless of anatomic location, methods include microsurgical replantation and nonmicrosurgical replantation, such as composite graft techniques. Numerous techniques to maximize tissue survival after revascularization have been described, including “pocket procedures” to salvage composite grafts, interposition vein grafts, and medicinal leeches to name a few. Artery-to-venous anastomoses have been performed with successful “arterialization” of the distal venous system in fingertip replantation. Although there is documented survival of free venous cutaneous flaps, to our knowledge this is the first report of a replanted composite body part (bone, tendon, soft tissues, and skin) utilizing exclusively multiple, microvascular, nonarterialized venous–venous anastomoses. We present a patient with an isolated band saw fillet amputation to the back of the thumb at the metacarpal–phalangeal joint region, resulting in a composite graft composed of bone, tendon, soft tissue, and skin. The hand wound provided no viable regional arterial inflow source, but there were multiple good caliber superficial veins present. The amputated tissues were replanted and revascularized by using only venous blood flow. The replanted part survival was 100% with excellent function of the digit. We conclude that a hand composite body part involving bone, tendon, soft tissues, and skin can survive replantation with a strict venous blood supply if sufficient good caliber, microvascular, venous–venous anastomoses are performed, granted that arterial inflow options are not available. This is an isolated case, yet introduces a new way of thinking regarding tissue replantation. PMID:18780032

  7. Catch crops impact on soil water infiltration in vineyards (United States)

    Cerdà, Artemi; Bagarello, Vincenzo; Iovino, Massimo; Ferro, Vito; Keesstra, Saskia; Rodrigo-Comino, Jesús; García Diaz, Andrés; di Prima, Simone


    Infiltration is the key component of the hydrological cycle (Cerdà, 1999; Bagarello et al.,, 2014; Zema et al., 2016). Infiltration determines the partitioning of rainfall into runoff and subsurface flow (Cerdà, 1996; Bagarello et al., 2006; Wang et al., 2016). In the Mediterranean, agriculture resulted in the degradation of the soil structure, reduction of the organic matter and increase in the soil losses (Cerdà et al., 2009; Laudicina et al., 2015; Iovino et al., 2016; Willaarts et al., 2016). There is an urgent need to restore the agriculture soils to avoid floods, reduce the carbon emissions and avoid reservoir siltation (Aksakal et al., 2016; Ben Slimane et al., 2016; Yagüe et al., 2016). Catch Crops are widespread used due to their impact on the soil fertility (Mwango et al., 2016; Nishigaki et al., 2016 ; Nawaz et al., 2016). Catch crops also increase the amount of organic matter but little is known about the effect on soil infiltration. Two paired plots were selected in Les Alcusses (Moixent municipality) in Eastern Iberian Peninsula to compare the infiltration rates between a 8-years catch crop (Vicia sp) with a control (plough) soil. The measurements were carried out by means of ring infiltrometer in August 2014 and December 2014 under dry and wet conditions (Cerdà, 2001; Di Prima et al., 2016). The results show that the steady-state infiltration rates were 1.8 higher during the summer period, and that the catch crops did not increase the infiltration rates.

  8. The positive impact of European subsidies on soil erosion rates in orange plantations (United States)

    Keesstra, Saskia; Jordán, Antonio; Novara, Agata; Taguas, Tani; Pereira, Paulo; Brevik, Eric C.; Cerdà, Artemi


    Soil erosion in orchards and vineyards has been found non-sustainable due to bare soils due to the use of herbicides and tillage (Novara et al., 2011; Taguas et al., 2015; Ochoa et al., 2016; Rodrigo Comino et al., 2016a; 2016b; 2016c). Citrus plantations in sloping terrains are also non-sustainable from the soil erosion point of view due high erosion rates and the damage caused on infra-structures (Cerdà et al., 2009; 2009b; Cerdà et al., 2011; Pereira et al., 2015). This is not uncommon in Mediterranean type Ecosystems (Cerdà et al., 2010) but there is a need to reduce the soil and water losses to achieve sustainability (Brevik et al., 2015; Keesstra et al., 2016). The use of mulches, geotextiles, catch crops, and vegetation was found to be very successful as a sustainable strategy to reduce the soil losses (Giménez Morera et al., 2010; Mwango et al., 2016; Nawaz et al., 2016; Nishigaki et al., 2016; Prosdocimi et al., 2016). Nowadays, chipped branches are applied in orchards and vineyards because of European subsidies; however little scientific data is available on the impact of the chipped branches mulch on soil erosion. In an orange plantation in Eastern Valencia, at the L'Alcoleja experimental station the impact of these chipped branches was tested under 45 mm h-1 rainfall simulations on laboratory plots of 0.5 m2 under with different covers of chipped branches. The results show that with a cover of 20 % with chipped branches soil erosion reduces by 78 %.

It was hypothesized that patients with overlap syndrome may have different clinical characteristics such as sputum eosinophilia, and better responsiveness to treatment with inhaled corticosteroid (ICS.Methods: Sixty-three patients with stable COPD (forced expiratory volume in 1 second [FEV1] ≤80% underwent pulmonary function tests, including reversibility of airflow limitation, arterial blood gas analysis, analysis of inflammatory cells in induced sputum, and chest high-resolution computed tomography. The inclusion criteria for COPD patients with asthmatic symptoms included having asthmatic symptoms such as episodic breathlessness, wheezing, cough, and chest tightness worsening at night or in the early morning (COPD with asthma group. The clinical features of COPD patients with asthmatic symptoms were compared with those of COPD patients without asthmatic symptoms (COPD without asthma group.Results: The increases in FEV1 in response to treatment with ICS were significantly higher in the COPD with asthma group. The peripheral eosinophil counts and sputum eosinophil counts were significantly higher. The prevalence of patients with bronchial wall thickening on chest high-resolution computed tomography was significantly higher. A significant correlation was observed between the increases in FEV1 in response to treatment with ICS and sputum eosinophil counts, and between the increases in FEV1 in response to treatment with ICS and the grade of bronchial wall thickening.

The safety of tipepidine in children and adults has already been established. It is reported that tipepidine inhibits G-protein-coupled inwardly rectifying potassium (GIRK-channel currents. The inhibition of GIRK channels by tipepidine is expected to modulate the level of monoamines in the brain. We put forward the hypothesis that tipepidine can improve attention deficit/hyperactivity disorder (ADHD symptoms by modulating monoaminergic neurotransmission through the inhibition of GIRK channels. The purpose of this open-label trial was to confirm whether treatment with tipepidine can improve symptoms in pediatric patients with ADHD.Subjects and methods: This was a 4-week, open-label, proof-of-efficacy pilot study for pediatric subjects with ADHD. Ten pediatric ADHD subjects (70% male; mean age, 9.9 years; combined [inattentive and hyperactive/impulsive] subtype, n=7; inattentive subtype, n=3; hyperimpulsive subtype, n=0 received tipepidine hibenzate taken orally at 30 mg/day for 4 weeks. All subjects were assessed using the ADHD Rating Scale IV (ADHD-RS, Japanese version, and the Das–Naglieri Cognitive Assessment System (DN-CAS, Japanese version.Results: A comparison of baseline scores and 4-week end-point scores showed that all the ADHD-RS scores (total scores, hyperimpulsive subscores, and inattentive subscores

Special thanks must also be made to Mitsuru Tanaka, President of the CCM, and Andrew Wallard, Director of the BIPM, for their support of the event. The event was coordinated by Jasmina Bolfek-Radovani, of the Institute of Physics, without whose tireless efforts the event would not have been as successful. The production of this issue of Metrologia would not have been possible without the help and support of its editor, Jeffrey Williams. The National Measurement System Directorate of the Department of Trade and Industry supported the conference and it was sponsored by DH Instruments and BOC Edwards. Additional financial assistance was also received from Chell Instruments Ltd, DH-Budenberg, GE Infrastructure Sensing, Hi-Pro Pressure Products Ltd, Kurt J Lesker Company Ltd and Leybold Vacuum UK Ltd. Finally we would like to thank all of the conference participants who made the event both technically stimulating and enjoyable. By the time the next CCM Pressure conference is held in Berlin in 2011, pressure science and technology will undoubtedly have moved on still further and we may see the culmination of work to realize primary pressure standards by more fundamental methods.

    Snyder, P. B.


    It is a great honor to receive the 2014 Nuclear Fusion Prize, here at the 25th IAEA Fusion Energy Conference. On behalf of everyone involved in this work, I would like to thank the IAEA, the Nuclear Fusion journal team, the IOP, and specifically Mitsuru Kikuchi, for their support of this important award. I would also like to acknowledge the many important contributions made by the other ten papers nominated for this prize. Our paper investigates the physics of the H-mode pedestal in tokamaks, specifically the development of a predictive understanding of the pedestal structure based on electromagnetic instabilities which constrain it, and the testing of the resulting theoretical model (EPED) against detailed observations on multiple devices. In addition to making pedestal predictions for existing devices, the paper also presents predictions for ITER, including methods for optimizing its pedestal height and fusion performance. What made this work possible, and indeed a pleasure to be involved with, was an extensive set of collaborations, including theory-experiment, multi-institutional, and international collaborations. Many of these collaborations have gone on for over a decade, and have been fostered in part by the ITPA Pedestal Group. The eight authors of this paper, from five institutions, all made important contributions. Rich Groebner, Tom Osborne and Tony Leonard carried out dedicated experiments and data analysis on the DIII-D tokamak, testing the EPED model over a very wide range of parameters. Jerry Hughes led dedicated experiments on Alcator C-Mod which tested the model at high magnetic field and pedestal pressure. Marc Beurskens carried out experiments and data analysis on the JET tokamak, testing the model at large scale. Xueqiao Xu conducted two-fluid studies of diamagnetic stabilization, which enabled a more accurate treatment of this important effect. Finally, Howard Wilson and I have been working together for many years to develop analytic formalism

  15. Cream Soda. The rhythm of everyday life

    Directory of Open Access Journals (Sweden)

    Eleonora Benecchi


    Full Text Available In this work I will focus my attention on a specific manga, Cream Soda by Adachi Mitsuru (1996. As suggested by Eco (1999, I will analyze this single work keeping in mind that it belongs to a medium and some genre practiced through this medium, but focusing my attention on the specific syntax of the speech of Adachi. This means that in this work I won’t talk about manga in general or in itself, at least, not in the foreground and in the first instance, but I will consider Adachi’s specific execution of the art of manga. This work will start from the analysis of single panels, and their relationship with each other inside the page layout, following the critical path indicated by Thierry Groensteen (1999, and will be then accompanied by the analysis of images and texts contained inside those panels, with special regard to their relationship with each other and with images and texts contained in other panels, following the lead of Barbieri (1995 and Pellitteri (1998.

    The analysis of the elements that this text brings together to create a coherent narrative, and those elements it will not, will show that to properly understand Adachi’s manga the reader must recognize the fictional nature of what he is reading and his function as co-author of the story. Obviously this reflection is based on a first level or narrative interpretation of the text because it is starting from this basic layer that all the other layers can be explored. This is also the reason why this work provides a punctual examination of the single panels.

    The analysis here proposed will also demonstrate that, despite many panels open up to different levels of readings, the activation of the second or third level of reading is not a given. It will also become evident, though, that if one stops at a first level reading, the most obvious one, the text in question isn’t really fulfilled according to its author’s expectations: the reader’s high engagement

  16. The impact of olive leaves, mosses and the burrowing of wild boars on soil erosion in olive orchards (United States)

    The main factor controlling soil erosion is vegetation cover (Cerdà and Doerr, 2005; Van Eck et al., 2016; van Hall et al., 2017). However, due to the removal of the vegetation in agricultural fields and the increase in soil erosion rates other factors arise as keys to control soil erosion rates and mechanisms (Ochoa-Cueva et al., 2016; Rodrigo Comino et al., 2016). Soil erosion rates in olive plantations are high due to the lack of vegetation cover as a consequence of intensive tillage and herbicides abuse (Taguas et al., 2015; Parras-Alcantara et al., 2016; Zema et al., 2016). This is also found in vineyards and other orchards around the world (Prosdocimi et al., 2016; Rodrígo Comino et al., 2016), and the reason to look for sustainable management techniques such as geotextiles, mulches or catch crops that will stop the accelerated soil erosion (Giménez Morera et al., 2010; Mwango et al., 2016; Nawaz et al., 2016a; 2016b; Nishigaki et al., 2016). All these management techniques are difficult to apply and have high costs. Natural solutions such as weeds to provide cover are very efficient and have no cost (Cerdà et al., 2016; Keesstra et al., 2016) and they can be adapted to the management of the farmers. In olive orchards under herbicide treatment there is a natural growth of mosses and the development of a litter layer composed of olive leaves. There is also burrowing by wild boars that "ploughs" the soil. This research evaluates the impact of the three items above on soil erosion. The measurements were carried out using simulated rainfall experiments over an area of 0.25 m2 at a rainfall rate of 55 mm h-1 during one hour (Cerdà, 1996; Prosdocimi et al., 2017) on 15 plots of mosses, 15 wild boar burrowed surfaces and 15 leaf covered surfaces during the winter of 2015. The soil erosion rates were 34 times greater in the wild boar burrowed soils, meanwhile the litter and mosses covered soils showed similar erosional responses and the soil erosion rates were

  18. Ruschita Romanian marble - 130 years of official exploitation and 130 m depth of architectural beauty around the word (United States)

    Cetean, Valentina


    Developed in a large metamorphic area, the marble deposit from Ruschita perimeter is the most important Romanian source for ornamental stone, the old quarry being operative since 1883. The closest locality offer the commercial name also, identical with the geological one as is defined in the technical referentials and in the denomination European standard. Ruschita is also an active quarry, developed by step-by-step expansion in depth (the initial extraction reached 130 m depth), but also in the adjacent areas. The important height of the open deposit offered the possibility to the owner, MARMOSIM SA, to apply an experimental extraction method, by underground mining. It is the only Romanian place, and few in the world, where this spectacular mining element can be found for dimension stone. The extraction gallery was built starting from the lower level of the old quarry and allowed obtaining nicer and bigger blocks. The Ruschita marble is a metamorphic stone with high crystallinity and medium size of crystals (until 0.2-0.5 mm). Has the basic colour from white and grey to pink, with many intermediary nuances generally given by grey veins and less by impurities from internal structure. The stone present irregular break, sometimes following the very narrow internal discontinuities, invisible at macroscopic analyse. The main physical - mechanical characteristics are presented below: Characteristic M.U. Value Apparent density Kg/m3 2680 - 2720 Water absorption % 0.12 - 0.21 Capillarity g/m2.s0,5 0.130-0.218 Porosity % 0.30 - 0.74 Compression strength N/mm2 85 - 120 Flexural strength MPa 15-18 Rupture energy J 5 Coefficient of frost cleftness % 10 -14 Abrasion resistance - Bohme cm3/50cm2 17-18 Salt crystallization % 0.1 Nowadays, the extraction in the Ruschita area is achieved by equipments from Dazzini, Fantini, Pellegrini, Korfamann, Caterpillar, Volvo and Komatsu. The average volume of blocks is bigger than 10-12 m2. The Ruschita marble can be easily cut at size and

The winner of the 2008 Nuclear Fusion award is Todd Evans et al for the paper `Suppression of large edge localized modes with edge resonant magnetic fields in high confinement DIII-D plasmas' (Nucl. Fusion 45 595-607). The awards were presented by the IAEA Deputy Director General, Werner Burkart, and the Chairman of the Board of Editors, Mitsuru Kikuchi, on 16 October 2008 at the 22nd IAEA Fusion Energy Conference in Geneva, Switzerland. Given the topicality of these papers for the ITER design, it is a matter of pride to the journal that the work should be published in Nuclear Fusion. Reviews Like many who have worked for a long time in the field, I still make use of Nuclear Fusion Reviews that go back 20 or 30 years. It is particularly useful, therefore, that the Board of Editors has been working to re-activate the review programme. The first fruits will appear in this issue, in the form of `A review of zonal flow experiments', by Akihide Fujisawa. The special procedures for Reviews should be noted: most specifically that they should normally be commissioned by the Board of Editors. However, not only is the Board of Editors working on a programme but I am sure that they would be pleased to consider suggestions for review subjects. Letters The reputation of Nuclear

    award was Steven A. Sabbagh et al for the paper entitled 'Resistive wall stabilized operation in rotating high beta NSTX plasmas' (Nucl. Fusion 46 635-644). Reviews Last year I announced a revival of Nuclear Fusion Reviews, following a decision by the Board of Editors. 'A review of zonal flow experiments', by Akihide Fujisawa was the first fruit of this. In 2010, we are expecting to publish further review articles, the first of which is entitled 'Gyrokinetic simulations of turbulent transport' by Xavier Garbet, Yasuhiro Idomura, Laurent Villard and Tomo-Hiko Watanabe. Letters At the 2009 Board of Editors Meeting in Atlanta, the current letters procedure was summarized and it was noted that the peer review time for Letters is quite variable. Some are accepted within a month of submission, others take longer. Since the purpose of Letters is to provide a route for rapid communication, this is quite an important matter. It was agreed that the Board of Editors would play a more active role in the Letter approval process. If a reviewer asks for a second revision the Editor or a Board of Editors member will be queried as to whether the submission should still be treated as a Letter rather than a regular Paper. The Board of Editors The following Board of Editors members reached the end of their term in 2009: Amanda Hubbard, Yaroslav Kolesnichenko, Kunioki Mima, Boris Sharkov and Michael Ulrickson. On behalf of the Nuclear Fusion Office and the Chairman of the Board of Editors, Mitsuru Kikuchi, I would like to thank them for their efforts in support of the journal. At the same time, we welcomed: Hiroshi Azechi, Xuru Duan, Richard Hawryluk, Sergey Konovalov, Bruce Lipschultz, Peter Norreys, Francesco Romanelli, Tony Taylor and Hartmut Zohm. I am sure that such an illustrious group does not need any introduction to the readers of Nuclear Fusion and I am confident that the new members can only further the success of the journal.
