Effect of New Suggested Ferroresonance Limiter on the Stability Domain of Chaotic Ferroresonance in the Power Transformer with Linear Core Model

This Paper studies the effect of new suggested ferroresonance limiter on controlling ferroresonance oscillations in the power transformer. It is expected that this limiter generally can control the ferroresonance. For studying these phenomena, at first ferroresonance is introduced and a general modeling approach is given. A simple case of ferroresonance in a three phase transformer is used to illustrate these phenomena. Then, effect of new suggested ferroresonance limiter on the onset of chaotic ferroresonance and control of these oscillations in a power transformer including linear core losses is studied. Simulation is done on a three phase power transformer while one of its phases is opened, and effect of varying input voltage on occurring ferroresonance overvoltage is studied. Results show that connecting the ferroresonance limiter to the transformer exhibits a great controlling effect on the ferroresonance overvoltage. Phase plane diagram, FFT analysis along with bifurcation diagrams are also presented. Significant effect on occurring chaotic ferroresonance, the range of parameter values that may lead to overvoltage and magnitude of ferroresonance overvoltage is obtained, showed and tabulated.

The axisymmetric long-wave interfacial stability of core-annular flow of power-law fluid with surfactant

The long wave stability of core-annular flow of power-law fluids with an axial pressure gradient is investigated at low Reynolds number. The interface between the two fluids is populated with an insoluble surfactant. The analytic solution for the growth rate of perturbation is obtained with long wave approximation. We are mainly concerned with the effects of shear-thinning/thickening property and interfacial surfactant on the flow stability. The results show that the influence of shear-thinning/thickening property accounts to the change of the capillary number. For a clean interface, the shear-thinning property enhances the capillary instability when the interface is close to the pipe wall. The converse is true when the interface is close to the pipe centerline. For shear-thickening fluids, the situation is reversed. When the interface is close to the pipe centerline, the capillary instability can be restrained due to the influence of surfactant. A parameter set can be found under which the flow is linearly stable.

The Proof Dilemma of Porter’s Hypothesis:Analysis of Its Verification Difficulties

The Porter Hypothesis,proposed by Michael E.Porter,suggests that stringent environmental regulations can enhance corporate innovation and competitiveness,challenging the traditional view that regulations increase business costs.It argues that regulations motivate firms to innovate,leading to improved productivity,cost reductions,and new market opportunities.However,there are proponents and critics in academia regarding the hypothesis.Supporters claim regulations change corporate behavior,reducing agency costs and boosting research and development.Critics argue that if win-win situations exist,businesses would naturally pursue them without regulatory incentives.Key challenges in proving or refuting the hypothesis include its various versions,the difficulty in quantifying innovation and competitiveness,the complex interplay between regulation,innovation,and competitiveness,and the varying impacts across industries and regions.Additionally,the effects may require a long time to manifest,and the hypothesis’s applicability is influenced by evolving environmental policies and market environments.Despite mixed empirical findings,the Porter Hypothesis provides a valuable framework for understanding the relationships among environmental regulation,innovation,and competitiveness,but its validation requires a more comprehensive assessment.

Evaluating the Discriminatory Power of DNA Barcodes in Panicoideae, Poaceae

DNA barcoding is a powerful technique for species identification with little morphological knowledge, by using short sections of DNA from a specific region of the genome. Two core barcode markers, rbcL and matK, and a supplementary nuclear ribosomal internal transcribed spacer region were used to examine the effectiveness of the markers for Poaceae barcoding using 133 individuals of 36 taxa across 23 genera of Korean Panicoideae. We also aimed to establish a DNA barcode database for the major weeds of Korean Panicoideae. All three markers revealed a good level of amplification and sequencing success. As a single DNA marker, the ITS region achieved the highest species resolution, followed by matK. Resolving power was increased when nrlTS was incorporated into the core barcode markers. The best resolving power was obtained with a combination of matK ＋ ITS with 89.7%, followed by rbcL ＋ matK ＋ ITS with 89.3%. Thus, rbcL may be not necessary as a DNA barcode for Panicoideae species identification, when considering cost and effectiveness. Instead, a combination of matK ＋ ITS is proposed as the most suitable DNA barcode for the species identification of Panicoideae, Poaceae. We conclude that DNA barcoding using a combination of matK ＋ ITS could be one of powerful techniques for the identification of Poaceae species, The barcode sequences were deposited to the National Center for Biotechnology Information （NCBI） database for public use.
