Cross-Correlation Analysis of Geomagnetic Observatory Components, X, Y, Z and the Geomagnetic Index, RC in Geomagnetic Exploration Studies.
Get PDFA cross-correlation study between the geomagnetic components (X, Y, Z) and the geomagnetic magnetospheric ring current activity (the RC index) is made for more than 80 worldwide geomagnetic observatories for days away from quiet time (disturbed days). Results suggest a strong relationship between the geomagnetic observatory measurements, particularly the X component, and the RC index. Strong coherence and correlation is observed between the X component and the RC index in all the observatory locations studied in all the geographical regions of the Earth. Cross-correlation coefficients ranged between 0.70 and 0.85 for the comparison, suggesting global phenomenon. However, the Y and Z components comparison with the RC index show low correlation and anti-correlation, with cross-correlation coefficients of between -0.55 and 0.50 in most of the observatory locations globally. This lack of clear correlation between the Y and Z components and the RC index suggests lack of influence of the external field variations, but consistent with the ring current influencing the rapid variations observed in the X components during disturbed days
On the Sunspot Group Number Reconstruction: The Backbone Method Revisited
Get PDFWe discuss recent papers very critical of the Group Sunspot Number Series (Svalgaard & Schatten [2016]). Unfortunately, we cannot support any of the concerns they raise. We first show that almost always there is simple proportionality between the group counts by different observers and that taking the small, occasional, non-linearities into account makes very little difference. Among other examples: we verify that the RGO group count was drifting the first twenty years of observations. We then show that our group count matches the diurnal variation of the geomagnetic field with high fidelity, and that the heliospheric magnetic field derived from geomagnetic data is consistent with our group number series. We evaluate the ‘correction matrix’ approach [Usoskin et al. 2016] and show that it fails to reproduce the observational data. We clarify the notion of daisy-chaining and point out that our group number series has no daisy-chaining for the period 1794-1996 and therefore no accumulation of errors over that span. We compare with the cosmic ray record for the last 400+ years and find good agreement. We note that the Active Day Fraction method (of Usoskin et al.) has the fundamental problem that at sunspot maximum, every day is an ‘active day’ so ADF is nearly always unity and thus does not carry information about the statistics of high solar activity. This ‘information shadow’ occurs for even moderate group numbers and thus need to be extrapolated to higher activity. The ADF method also fails for ‘equivalent observers’ who should register the same group counts, but do not. We conclude that the criticism of Svalgaard & Schatten [2016] is invalid and detrimental to progress in the important field of long-term variation of solar activity
Quantum Mechanics and General Relativity: Creation Creativity
Get PDFThis article is concerned with a new concept of quantum mechanics theory depending upon the two components: matter and anti-matter. The article also links quantum mechanics and general relativity. Linking the two theories has been a long-pursed attempt by many scientists. The article gives the reader the chance to understand the microscopic and macroscopic worlds by the two theories linked by one equation.
Quantum mechanics and general relativity are the eye of science by which we look at the universe. Quantum mechanics is concerned with microscopic level and general relativity is concerned with macroscopic level. Many scientists have attempted to link the two theories but in vain. The following papers describe the way in which one can have a scientific explanation of the universe with one theory called the Creation Theory

Biosorption of Eriochrome black T (EBT) Onto Waste Tea Powder: Equilibrium and Kinetic Studies
Get PDFBiosorption of EBT molecules from aqueous solutions onto waste Tea powder (WTP) have been examined in a batch biosorption process. The biosorption procedure was found to be dependent on biosorbent dose, pH of solution, initial dye concentration, and contact time. The experimental equilibrium biosorption data were inspected by Langmuir, Freundlich, Temkin and Dubinin ̶ Radushkevic isotherms models. The Langmuir model gave the best fit by higher correlation coefficient (R2 = 0.997, it assumes as monolayer adsorption). The maximum biosorption capacities determined from the Langmuir isotherm model was 111.11 mg/g, at optimum circumstances. The kinetic studies showed that the biosorption operation of the EBT dye obeyed well pseudo-second-order model. According to the determined biosorption capacity, waste tea powder is considered to be as an effective, low cost, and environmentally friendly biosorbent for the removal of EBT dye from aqueous solutions
Experiments on The Effects of Reagants and Electricity on Seed Germination Growth and Viability
Get PDFMost plants develop from seeds. Dry seeds under dormant condition show no sign of life. Only on the availability of stimulants like water, an adequate temperature etc., do seeds undergo biochemical reactions and develop in to plants. Generally the first and most important thing for seeds to germinate is the availability of an optimum quantity of water. Under all circumstances seeds are soaked in ‘plain’ water before germination. They swell up, their surfaces become smooth and slowly radicles protrude. Various chemical changes occur within a seed during germination. Now these reactions may be altered by use of reagents. If the chemical natures of the constituents of seed layers are known, it may be possible to change the chemicals by suitable reactions. For E.g. if aldehydic group be present, it may either be oxidized or reduced. But if this occurs the entire process of germination and plant growth ‘should’ be affected. In this paper chemical effects on seed germination have been expounded in detail
Gravitation - Flat Power Field
Get PDFA new principle of origin and the nature of the action of gravity forces are proposed. Forces of universal attraction have plane-symmetrical directions. On this basis, it becomes possible to reconsider certain regularities in natural science. The new principle of gravitation will allow to explain physical paradoxes, to improve methods of scientific research and some technological processes
Synthetic Methods of Propylene Carbonate and Research Progress
Get PDFPolyurethane is an important polymer material, but its raw material, isocyanate, is toxic, which caused the inconvenience for the production and transportation, in order to solve the problem of toxic material, a green synthetic method of non-isocyanurate polyurethane (NIPU) can be developed and research on no-toxic isocyanate as raw material is the new direction of polyurethane in recent years. Because the propylene carbonate is an important raw material for the synthesis of non-isocyanate polyurethanes, therefore, in this article, several synthetic methods of propylene carbonate were described, the advantages and disadvantages of these synthetic methods for propylene carbonate were compared, and the future development was looked forward
