Real root

This paper points out several properties of the solutions of the equation determining the IRR, which includes the equivalence of this equation with an algebraic equation whose degree is less than or equal to n, the existence of solutions, the number of real solutions, the relative position of real roots with -1 and 0 and some illustrations for that.

Suboptimal tissue perfusion and oxygenation may be the root cause of certain perioperative complications in neonates and infants having complicated aortic coarctation repair. Practical, effective, and real-time monitoring of organ perfusion and/or tissue oxygenation may provide early warning of end-organ mal-perfusion.

This paper assesses empirically the effects of real oil price shocks on the food inflation in Kazakhstan for the monthly period 2004-2019 by using a VAR model. Standard unit root tests do not yield reliable results in the presence of breaks. In this regard, Zivot and Andrews (1992) has been tested with the help of unit root test. Food prices have been proven to be I (1) according to the Zivot and Andrews (1992) test, while I (0) is according to the ADF test. In subsequent steps, the causality test of the variables was performed.

In this paper, we discuss a new algorithm to find a non-zero real root of the transcendental equations using series expansion. This proposed method is based on the inverse series expansion, which gives a good approximate root than some other existing methods. The implementation of this algorithm is presented in Matlab and Maple. Sample numerical examples are presented to illustrate and validate the efficiency of the proposed algorithm. The method will help to implement in the commercial package for finding a real root of a given transcendental equation.

This study aims to investigate the relationship between real non-oil GDP growth of Azerbaijan and exchange rate and oil prices. Zivot-Andrews unit root test is applied to deal with structural breaks in data and the Gregory-Hansen (GH) test for robustness. While conventional unit-root tests decision that the series are not stationary at their level, the Ziwot-Andrews test decision that the series is stationary with structural break.

Let G be a connected real semisimple Lie group with finite center and θ be a Cartan involution of G. Suppose that K is the maximal compact subgroup of G corresponding to the Cartan involution θ. The coset space X = G/K is then a Riemannian symmetric space. Denote by g the Lie algebra of G and g = k + p the Cartan decomposition of g into eigenspaces of θ. Let a be a maximal abelian subspace in p and Σ be the corresponding restricted root system.

Lead (Pb) and mercury (Hg) are persistent hazardous metals in industrially polluted soils which can be toxic in low quantities. Metal toxicity can cause changes at cellular and molecular level which should be studied for better understanding of tolerance mechanism in plants.

The aim of this paper is to analyze empirically the relationship between sectoral Foreign Direct Investment (FDI) and macroeconomic variables in the long-run and short-run in Turkey for the period from 2005 to 2016. The cointegration analysis and error correction models are used to test long-run relationship and short-run effects respectively. It is expected that the using of sectoral level data may disentangle the relationship FDI and macroeconomic variables.

Despite the great interest in using halophyte Salicornia europaea L. as a crop in extreme saline habitats, little is known about the role played by associated endophytic bacteria in increasing tolerance of the host-plant to nutrient deficiency. Main objectives of this study were to investigate the community composition of diazotrophic endophytes of S. europaea grown under natural conditions, and determine the proportion of plant-growth promoting bacterial strains able to fix N2. To quantify the abundance of diazotrophic bacterial endophytes in stems and roots of S.

Highly tensile manganese steel is in great demand owing to its high tensile strength under shock loads. All workpieces are produced through casting, because it is highly difficult to machine. The probabilistic aspects of its casting, its variable composition, and the different casting techniques must all be considered for the optimisation of its mechanical properties. A hybrid strategy is therefore proposed which combines decision trees and artificial neural networks (ANNs) for accurate and reliable prediction models for ore crushing plate lifetimes.

The question of whether a dislocation can accelerate through the shear-wave speed “barrier” is addressed by analyzing the transient motion of a Volterra dislocation at the instant when the velocity equals the shear-wave speed in the presence of acceleration, which requires an asymptotic analysis at a double root (–at the transition from subsonic to supersonic a pair of complex conjugate roots becomes a double real —).

In conclusion, let us outline a different argument, very much in the spirit of Lectures 8 and 5. We considered in these lectures the space of polynomials of a certain type (such as x3 + px + q or x5 − x + a) and saw that the set of polynomials with multiple roots separated the whole space into pieces, corresponding to the number of roots of a polynomial. The set of polynomials with multiple roots is a (very singular) hypersurface obtained by equating the discriminant of a polynomial to zero. Unlike the real case, the set of zeros of a complex equation does not separate complex space.

That is all: just a computer procedure to approximate a real root. From the narrow perspective of treating mathematics as a tool to solve real life problems, this is of course sufficient. However, from the point of view of mathematics, shouldn’t a student be interested in roots of polynomials in general? Fourth degree? Odd degree? Other roots, once one is found? Rational roots? Total number of roots? Not every detail need be explained, but even the average student will have his life improved by the mere knowledge that there are such questions, often with answers, e.g.

Corn gluten meal is a natural pre-emergent fertilizer (9.5-0.5-0.5) that reduces the germination and establishment of troublesome annual weeds. It is available as a powder or in granular form. It is 60 percent protein and approximately 10 percent nitrogen by weight. It is a by-product of the wet milling process and commonly used in pet and livestock feed. It can be used in vegetable gardens as a fertilizer and can help with weed control, but be careful. It can damage the germination of your food crops. Use it only after your vegetable seeds are up and young plant roots are...
