Green and Sustainable Chemistry (GSC) , 2017, DOI: 10.4236/gsc.2017.72011
Abstract: An efficient greener one pot synthesis of dimethyl-dihydro-7H-chromeno[3, 2-h]quinolin-8(9H)-one derivatives has been synthesized through cyclization of aromatic aldehyde, dimidone and 8-hydroxy-quinoline through one-pot condensation method is described. The synthesized compounds are screened for further biological activities against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis, Bacillus using cut plate method and disc diffusion method.
Hydrolytic Degradation Study of Lansoprazole, Identification, Isolation and Characterisation of Base Degradation Product  [PDF]
Satyanarayana Battu, Vasudev Pottabathini
American Journal of Analytical Chemistry (AJAC) , 2015, DOI: 10.4236/ajac.2015.62013
Abstract: Lansoprazole degradation is accelerated in both acidic and basic medium in water. The present investigation deals with the hydrolytic degradation of Lansoprazole. Acidic medium degradation show all known impurities and degradation products whereas basic degradation studies show new impurity which has higher molecular weight than Lansoprazole. New impurity was identified, isolated using mass based auto purification system and characterised by 1H NMR, 13C NMR, HMBC, HSQC, NOE, COSY and HRMS experiments. Isolated impurity was showing molecular weight of 467.10, molecular formula of C23H16F3N5OS and its name is 7-(3-Methyl-4-(2,2,2-trifluoroethoxy) pyridin-2-yl)-7H-benzo[4,5]imidazo[2,1-b]benzo[4,5]imidazo[2,1-d][1,3,5]thiadiazine.
Web Enabled Multi-Layer Geo-Database for Moinabad Mandal in Rangareddy District, Telangana  [PDF]
Simhachalam Alajangi, Satyanarayana Prasad Nerella
Journal of Geographic Information System (JGIS) , 2014, DOI: 10.4236/jgis.2014.66057
Abstract: The importance of Web-based GIS applications for government is to analyze the information they produce and to establish their impact on efficiency, effectiveness and transparency. The potential of Remote Sensing and GIS provides cost and time-effective resource database. An attempt was made to develop a Web enabled Geo database for the Moinabad Mandal, Ranga Reddy District, Telangana. Further this database was used to develop a web enabled multi-layer geo database using ArcGIS Server. It enables the users to know the information and take better decisions, better planning in different rural development sectors.

Additional Space Dimension in Bound Spaces Created by a Central Object  [PDF]
T. V. B. S. Satyanarayana Murthy
Journal of Applied Mathematics and Physics (JAMP) , 2015, DOI: 10.4236/jamp.2015.32019
Abstract: Space is a common entity in any static or dynamic system of objects whether the system is a bound system or an open system. Space is described by either measured or abstract dimensions. All motions, momentum and energy transfers take place in space in any given system of objects. By understanding space we understand many physical phenomena happening in space. One method is to observe similarities among phenomena, deduce possible relations and validate the relations through known results. De Broglie wavelength for matter waves is a typical theorized abstract dimension existence of which is established through experiments later. In this paper, the author studies two bound spaces in two bound systems, namely, atomic bound systems and gravitationally bound systems. Both these bound systems have similar characteristics; they have inertial masses in motion with constant kinetic energies for a given orbital distance around the respective central object. In atomic bound space, the central object is the central positive charge which plays the role of creating the bound space around it. In gravitationally bound space, it is the central mass that plays the same role. Thus for these two bound systems a common constitutive relation between the energies of inertial masses in kinetic state, their distance from central object could be present. By noticing the similarities of the two systems, the author proposes such a relation through introduction of an additional space dimension. The existence of the proposed additional dimension is proved in this paper by considering hydrogen atom for atomic bound space and by considering any gravitational system for gravitationally bound space. Though the magnitude of the additional space dimension is different in both the situations, the additional space dimension exists. It is observed that in hydrogen atom the additional space dimension is a constant for the given positive charge of hydrogen atom when electron is in any energy state having principal quantum number of any value from 1 to 5 and with the orbital quantum number zero. For other quantum numbers additional space dimension exists. In the case of gravitational bound space, the additional space dimension is constant for a given mass of the central object for any energy of orbiting inertial mass. The author concludes that total mass energy of an inertial mass having a constant kinetic energy in any bound space is related to an additional space dimension defined by the constitutional property of the central object creating
Financialisation Impacting Diversification? Evidence from Indian Equity & Commodity Markets  [PDF]
Siddula Narsimhulu, D. Satish, S. V. Satyanarayana
Theoretical Economics Letters (TEL) , 2016, DOI: 10.4236/tel.2016.65088
Abstract: Investors are constantly looking at diversification of risks by combining equities with other assets in their portfolio. Apart from fixed income securities and real estate related instruments, commodities are also being increasingly used as a portfolio diversification strategy. But the overwhelming presence of financial institutions and funds in the commodity markets has resulted in financialisation of commodity markets leading to a greater correlation between equities and commodities especially during recession. This has lead to a reduction in diversification benefits. The paper attempts to study the diversification benefits of investing both in Indian commodities and equities markets in different economic environments using VAR Impulse Response Functions with an aim to find out whether financialization exists. The research found that there was absence of interdependence between the Indian equity and commodities markets which offered a good opportunity for diversification. Also the equities market and commodities market during recession were totally decoupled which showed that the financialization was not present in Indian commodities market and there was a greater scope for diversification during the recession.
Derivation of Specific Velocity of Body Moving under Gravity with Zero Total Energy  [PDF]

Mathematical solutions predict abstract conditions that indicate limits or bounds for physical processes. Generally, experimental verifications and physical observations on physical processes validate the mathematical predictions. Sometimes these predictions lead to new theories and concepts that form basis of better understanding of the natural processes. Gravitational interactions between bodies are natural physical processes. A smaller body moves under the influence of gravity, due to the gravitational effect of another large body. Newton’s classical gravitational theory addresses the interactions at low velocities. Einstein’s general relativity provides firm basis for gravitational interactions. Observations over past 100 years prove the mathematical precision and predictions of general relativity. Einstein’s special relativity forms the foundation of quantum physics. In this paper, the author applies concepts of special relativity to classical two body Newtonian gravitational problem. The study predicts a new mathematically viable condition that when a body moves at a specific velocity derived in this paper, the total energy of the moving body is zero. The specific velocity is a constant. At velocities far less than specific velocity, the total energy is negative and is equal to classical value of half the potential energy. At velocities, greater the specific velocity the total energy is positive. The specific velocity condition also enables determination of specific mass of gravitating body, as well as the specific distance of the moving body from gravitating body, at which the total energy of moving body is zero.
