Analytical Spectrometric Study For Determining Dapagliflozin Propanediol Monohydrate Individually Or In Presence Of Metformin Hydrochloride In Tablets Formulation
Get PDFFirst simple spectrophotometric method was developed and applied to determine Dapagliflozin Propanediol Monohydrate by Zero Spectrophotometry and First Derivative Spectrophotometric method for determining of Dapagliflozin Propanediol Monohydrate (DAPA) in the presence of Metformin Hydrochloride (MET). Zero spectrophotometric (ZS) was applied for the determination of (DAPA) at 223.5 nm. Linearity range was (2.61– 31.23) µg/mL. Regression analysis showed a good correlation coefficients R2 = 0.9989. The limit of detection (LOD) and limit of quantification (LOQ) were to be 0.569 µg/mL and 1.724 µg/mL, respectively. Derivative spectrophotometric (1DS) was applied for the determination of (DAPA) in the presence (MET). (DAPA) was determined at 233 nm (1D233). Linearity ranges were (5.21 – 41.64) µg/mL for (DAPA). Regression analysis showed a good correlation coefficients R2 = 0.9994. The limit of detection (LOD) and limit of quantification (LOQ) were to be 0.732 µg/mL and 2.218 µg/mL for (DAPA). The proposed Zero spectrophotometry method was applied to analysis individual (DAPA), and the derivative (1D233) method was applied to analysis (DAPA) individually or with (MET) combination in Syrian trademark drugs
Regional Boundary Asymptotic Gradient Full-Order Observer in Distributed Parabolic Systems
Get PDFThe purpose of this paper is to explore the concept of the regional boundary asymptotic gradient full order observer (RBAGFO-observer) in connection with the characterizations of sensors structures. Then, we present various results related to different types of measurements, domains and boundary conditions for distributed parameter systems (DPSS) in parabolic systems problem. The considered approach of this work is derived from Luenberger observer theory which is enable to estimate asymptotically the state gradient of the original system on a sub-region of the domain boundary in order that the RBAGFO-observability notion to be achieved. We also show that there exists a dynamical system for the considered system is not BAGFO-observer in the usual sense, but it may be regional RBAGFO-observer
The Computational Approach for Recommendation System Based on Tagging Data
Get PDFRecommendation approaches like a platform for learning algorithm. We can use some predicted values to put them in the data pipeline forlearning. There is a hard nuance of how to calculate the similarity measurewhen we have a small number of actions at all, its not a new user or item to use cold start methods, we just have not enough quantity to say it may be interpreted like regularity. The frequency of tags what we would have fromusers will have a huge impact to predict his future taste. The article describes created a computational approach using as explicit and as implicit feedbacks from users and evaluates tags by Jaccard distance to resolve this issue. To compare results with existed numerical methods there is a comparison table that shows the high quality of the proposed approach
Spectacular Exponents: A semi modular Approach to Fast Exponentiation
Get PDFThis paper introduces a computational scheme for calculating the exponential bw where b and w are positive integers. This two-step method is based on elementary number theory that is used routinely in this and similar contexts, especially the Chinese remainder theorem (CRT), Lagrange’s theorem, and a variation on Garner’s algorithm for inverting the CRT isomorphism. We compare the performance of the new method to the standard fast algorithm and show that for a certain class of exponents it is significantly more efficient as measured by the number of required extended multiplications.  
Fuzzy Graphs
Get PDFIn this paper, neighbourly irregular fuzzy graphs, neighbourly total irregular fuzzy graphs, highly irregular fuzzy graphs and highly total irregular fuzzy graphs are introduced. A necessary and sufficient condition under which neighbourly irregular and highly irregular fuzzy graphs are equivalent is provided. We define d2 degree of a vertex in fuzzy graphs and total d2 -degree of a vertex in fuzzy graphs and (2, k)-regular fuzzy graphs, totally (2, k)- regular fuzzy graphs are introduced. (2, k)- regular fuzzy graphs and totally (2, k)-regular fuzzy graphs are compared through various examples
Decrypting the Central Mystery of Quantum Mathematics:: Part 1. New Axioms Explain the Double Slit Experiment
Get PDFThis article proposes a solution to the double slit experiment of Quantum Mechanics. We attack the problem from a previously untried angle. Unsolved math problems must be attacked from unexpected angles because every conventional approach has already been tried and failed. Richard Feynman warned that the quantum world is such a strange place that humans can’t understand it. There is empirical evidence of particles following zero energy waves backwards, although that is counterintuitive. Schr˝odinger waves carry zero energy: they carry probability amplitudes instead. In our proposed model zero energy Schr˝odinger waves emanating from every point on the target screen pass backwards through the two slits, interfere at the particle gun, and a particle randomly chooses which wave to follow backwards. Once that decision is made the particle follows its wave with a probability of one, through only one slit (it doesn’t matter which slit) and inevitably strikes that point from which its wave emanates. This produces the same math and same pattern on the target screen. We propose three Axioms of the Theory of Elementary Waves (TEW) as a better platform for mathematics in this experiment than the Axioms of QM. This constitutes a paradigm shift
Synthesis, Spectroscopic Characterization And Antimicrobial Evaluation of Novel Nitrogen Containing Metal Complexes
Get PDFFour novel Mn(II), Co(II), Cu(II) complexes with nitrogen containing ligand (L) i.e. N,N-((Z)-ethane-1,2-diylidine)bis(2-amino benzo hydrazide) have been synthesized and structurally characterized by elemental analysis, spectral, thermal (TG/DTG), molar conductance and magnetic susceptibility measurements. From the spectroscopic and magnetic studies it has been concluded that all complexes have a six coordinated octahedral geometry. The Schiff base and their metal complexes have also been screened for their antibacterial and antifungal activities by using a modified Kirby-Bauer disc diffusion method
Light Quantum Induces The Measurement Paradox
No full textWe learn from Quantum Mechanics that the observation of the microscopic world, the measurement (M) of a quantum object, i.e. a particle, inexorably modifies the physical system we wish to examine.
What happens is that with the M it takes place a reduction of the state vectors, that is the ‘wave function collapse’ of the measured particle.
Why does it happen? No one knows.
The enigma of the so-called Measurement Paradox, in our opinion, could be solved if we considered that the light quantum(LQ), as suggested by the Principle of Equivalence Mass-Energy, carries out a dynamic-mass equivalent to its energy. The LQ is indispensable to carry out a M.
No M can be carried out without using the quantum of light.
Calculus show that a photon of the optic band hits an electron with a momentum bigger than the mass of the electron itself.
This may explain why the M induces the implosion of the quantum object observed, together with the collapse of its wave function, giving rise to the Measurement Paradox
Effect of Terbium Additions on Microstructural, Thermal and Mechanical Properties of Eutectic Sn-3.5Ag Pb- Free Solder for Low Cost Electronic Assembly
Get PDFThis work methodically concentrated on the effect of a trace amount of rare earth element terbium, Tb (0.1, 0.2, 0.3, 0.4 and 0.5 wt. %) on the properties of eutectic Sn-3.5 wt. %Ag were studied. The results indicated that addition of Tb rare earth can be refined the microstructure of the solder and intermetallic compound (IMC) Ag3Sn phase appeared in the solder matrix. Add a few quantity of rare earth Tb enhances the hardness and strength of eutectic Sn-Ag lead free solder joint. Also, results indicate that adding Tb to the eutectic Sn-3.5Ag remarkably enhances solderability, reliability, thermal and mechanical properties. It is also found that increasing in mechanical strength can depend on crystalline size refining in addition to some regular precipitates from IMC, Ag3Sn
