    This study was undertaken to use the variable loadings in linear discriminant analysis (LDA) to determine the most important predictors for the discrimination of tick-borne diseases (TBDs), particularly babesiosis and anaplasmosis and predict the group membership from the predictors. In total, 163 cattle, from different localities at Dakahlia Governorate, Egypt, were investigated in 2012 and 2013 for the presence of TBDs. All cattle were clinically examined and a clinical index score was determined for each cow. Blood samples were also collected from each animal for adopting microscopy and diagnostic laboratory methods. Out of the examined cattle, 83 animals were acutely-ill (Babesia bovis and Anaplasma marginale were identified in 11 and 10 animals, respectively), while 80 cows were apparently healthy but having previous attacks of blood parasites (23 animals harbored anaplasma marginale (asymptomatic carriers)). The remained 119 animals were negative to TBDs. Fourteen animals were not survived and 149 cases were survived. As the result of the first LDA to discriminate babesiosis, anaplasmosis and negative to TBDs, 89.0% of animals were correctly classified; 78.8% (26/33) for anaplasma, 100% (11/11) for babesia infections, 90.8% (108/119) for negative to TBDs, respectively. The important predictors for the discrimination were oculonasal discharge, bloody feces, hemoglobinuria, bloody feces and respiratory rate. On the other hand, the second LDA discrimination showed high classification accuracy of 87.1% for the discrimination of survivors and non-survivors; 89.9% (134/149) for survivors and 57.1% (8/14) for non-survivors, while the important predictors included oculonasal discharge, recumbent posture and nervous sign

    Process for the production of metal nitride sintered bodies and resultant silicon nitride and aluminum nitride sintered bodies

    A process for the manufacture of metal nitride sintered bodies, in particular, a process in which a mixture of metal nitrite powders is shaped and heated together with a binding agent is described. Of the metal nitrides Si3N4 and AIN were used especially frequently because of their excellent properties at high temperatures. The goal is to produce a process for metal nitride sintered bodies with high strength, high corrosion resistance, thermal shock resistance, thermal shock resistance, and avoidance of previously known faults

    Embrittlement in Neutron Irradiated Niobium

    Get PDF
    This paper discusses the effect of neutron irradiation on the embrittlement of niobium. The irradiation was carried out at about 100℃ to a neutron does of 2.9×10^n/cm^2 (<1 MeV) and measurements were made of the yield stress, fracture stress and fracture strain in the temperature range from liquid nitrogen to room temperature. The interaction of dislocations produced by deformation with irradiation-induced defects was studied by transmission electron microscopy. The fracture surfaces were examined using a scanning electron microscope. The brittle fracture stress was evaluated under theory of the dislocation and by the strain-energy method. Based on the results obtained, a possible mechanism for the fracture in neutron irradiated niobium was discussed

    A Perspective on Frugality in Growing Economies: Triggering a Virtuous Cycle between Consumption Propensity and Growth

    Get PDF
    The relationship between Growing economies have recovered from the global financial crisis faster than many developed economies and increased the consumption significantly over the past years. In light of the role of their consumption growth in global sustainability, this paper analyzes the decisive factors leading to a virtuous cycle between consumption propensity and investment in growing economies. An empirical analysis was conducted to identify the contributing factors to such a cycle in 40 countries. They could be divided into three economic groups by the marginal propensity to consume. The results suggest that growing economies suffer from an autarky cycle between consumption and GDP due to insufficient investment elasticity against consumption elasticity while advancing and advanced economies allow GDP growth to induce investment efficiently. A possible trigger for inducement of investment by growth in growing economies can be 'frugality'

    A Transition from Consumption-Dependent Development to Investment-Driven Development: A Comparison of 40 Countries

    Get PDF
    Following up the contrasting behaviors that growing economies suffer from an autarky cycle between consumption and economic growth. Advancing and advanced economies allow GDP growth for inducing investments efficiently. An empirical analysis was conducted in 40 countries, inspired by Samuelson’s multiplier-accelerator model, to examine a mechanism for switching from an autarky cycle to an investment-inducing virtuous cycle. The results suggest that a correlation between consumption growth and investment intensity is crucial to enable a shift from an autarky cycle to a virtuous cycle. The transition dynamism of economic cycles in these countries in the last three decades is also analyzed

    Catalyst Role of Government R&D Inducing Hybrid Management in Japan: Lessons for Emerging Economies

    Get PDF
    Japan has achieved conspicuous technology advancement and subsequent productivity increase by overcoming threats and constraints of sustainable development of economy and society. The achievement can be attributed to a sophisticated combination of industrial efforts and government stimulation. This paper analyzes the government role in inducing industrial strength in Japan. Empirical analyses were conducted focusing on technology driven development trajectory between Japan and the US over the last two decades. The results reveal that Japan incorporates sophisticated mechanism enabling the hybrid management of technology fusing indigenous strength and learning ability. While the combination of government and industry stagnated in the 1990s, a swell of reactivation emerged in the early 2000s. This can largely be attributed to revitalization of the mutual interaction between government and industry. Such a catalyst role of government R&amp;D inducing the hybrid management demonstrated by Japan would provide a new insight in emerging economies

    Probing Rotation of Core-collapse Supernova with Concurrent Analysis of Gravitational Waves and Neutrinos

    Full text link
    The next time a core-collapse supernova (SN) explodes in our galaxy, vari- ous detectors will be ready and waiting to detect its emissions of gravitational waves (GWs) and neutrinos. Current numerical simulations have successfully introduced multi-dimensional effects to produce exploding SN models, but thus far the explosion mechanism is not well understood. In this paper, we focus on an investigation of progenitor core rotation via comparison of the start time of GW emission and that of the neutronization burst. The GW and neutrino de- tectors are assumed to be, respectively, the KAGRA detector and a co-located gadolinium-loaded water Cherenkov detector, either EGADS or GADZOOKS!. Our detection simulation studies show that for a nearby supernova (0.2 kpc) we can confirm the lack of core rotation close to 100% of the time, and the presence of core rotation about 90% of the time. Using this approach there is also po- tential to confirm rotation for considerably more distant Milky Way supernova explosions.Comment: 31pages, 15figures, submit to Ap

    Dual Hybrid Management of Technology: Co-evolution with Growing Economies

    Get PDF
    Given the increasing significance of the co-evolution between advanced and growing economies for problem-solving innovation that aims at solving global critical issues, this paper attempts an empirical analysis to identify the optimal co-evolutionary trajectory, which could benefit both advanced and growing economies. While Japan has succeeded to develop the hybrid management of technology fusing indigenous strength and learning ability, it has revealed some limitations during the global simultaneous economic stagnation. The analysis suggests that the dual hybrid management of technology coevolving also with growing economies is decisive to the problem-solving innovation of the nation. This benefits nations in growing economies as well. This paper provides new insights into the problem-solving innovation, and also inducing strategy of growing economies for global sustainability
