The Klein–Gordon Equation with Modified Coulomb Potential Plus Inverse-Square–Root Potential in Three-Dimensional Noncommutative Space
Get PDFIn present work, the three-dimensional modified Klein-Gordon equation (MKGE) is analytically solved under modified Coulomb potential plus inverse-square–root potential, in the symmetries of noncommutative quantum mechanics (NCQM), using the generalized Bopp’s shift method. The new energy shift (ground state, first excited state and excited state) is obtained via first order perturbation theory in the 3-dimensional noncommutative real space (NC: 3D-RS) symmetries instead of solving MKGE with the Weyl Moyal star product. It is found that the perturbative solutions of discrete spectrum for studied potential depended on the parabolic cylinder functions, the Gamma function, the discreet atomic quantum numbers and the potential parameters (and), in addition to noncommutativity parameters (and)

Get PDFThis study reveals the fractal structure of gas giants and their moons. For this purpose, fractal analysis of Jupiter, Saturn, Uranus, Neptune and 182 moons was performed based on their radius (size). The results obtained reveal the fractal geometry of the planet / moon systems within the outer Solar system (SS). The resulting fractal dimensions (D) range from -0.57 to -1.43, decreasing with distance from the Sun. This requires a thorough analysis
Voltammetric Study For Cuso4 in Presence of Safranin (Saf ) in Hcl Solutions using New Multicarbon Nanotubes Doped with Nano Tantalum Pentoxide Working Electrode
Get PDFRedox reaction for CuSO4 in the absence and presence of safranin (suffranine) was studied. We applied new electrode made from multicarbon nanotubes (MCNT) and nano (Ta2O5) in a mixture with 80% MCNT and 20% (Ta2O5) by weight. Two drops paraffin oil was added, drying till dryness in tip of copper electrode covered with heat shrink polymer to do good isolation. The electrode was purified and put in oven at 90°C till working in the morning. Scan rate effect was done for the redox reactions in absence and presence of safranin to explain the type of the used reactions in the study electrode chemically. The stablilty constants and Gibbs free energies of complexation resulting from the interaction of CuSO4 with safranin in 0.1 M HCl at 27.5°C were evaluated and discussing their resulting data
Oxidative Cleavage of Solbutamol by N- Chloro Saccharin in Aqueous Acetic Acid Medium
No full textKinetic oxidation of Salbutamol by N-Chlorosaccharin, in aqueous Acetic acid medium, shows first-order dependence on [NCSA] and [H+], and fractional order on [Solbutamol]. The variation of [H+] and [Sacharin](reaction product) has a remarked effect on the rate of reaction(rate decreases). Activation parameters for the reaction have been evaluated from the Arrhenius plot by studying the reaction at different temperatures. The stoichiometry was found to be 1:1, and the products of oxidation were found to be 3-hydroxy methyl,4-hydroxy benzene carbaldehyde, Saccharin) and territory ammine as bi-products. The rate law has been derived on the basis of experimental Kinetic data and a plausible mechanism has been proposed
Atrans-Dinitrodiazenofuroxan Isomers-A DFT Treatise Lemi Türker
Get PDF1,2,5-oxadiazole (furazanes) and their N-oxides are high-energy compounds. 4,4’-Dinitro-3,3’-diazenofuroxan is a powerful high-density high-explosives with performance comparable to that of other high-density high-explosives. Presently, isomers of trans-dinitrodiazenofuroxan are considered at the levels of B3LYP/6-31G (d, p) and B3LYP/cc-PVTZ. Various geometrical and quantum chemical characteristics obtained are discussed. For the density calculations and mono ionic forms of these isomers UB3LYP/6-31G(d,p) and UB3LYP/6-31+G(d) type calculations have been performed, respectively. These ionic species are also found to be stable. Calculated IR, UV-VIS and 13C spectra are discussed
Synthesis And Characterization And Performance Evaluation Of Poly (Ester Amide) Urethane Derived From Thevetia Nerrifolia Seed Oil From Nigeria
Get PDFThevetia nerrifolia seed oil was extracted from the seed-bearing oil using hot extraction method involving the use of Soxhlet apparatus. The oil was characterized for physicochemical properties which include; specific gravity, refractive index, acid value, iodine value, and saponification value respectively. N, N-bis (2-hydroxyl ethyl) Fatty amide was obtained from the oil by reacting the oil with diethanolamine at 120oC, which was then reacted with phthalic anhydride at 140-150oC to give poly (ester amide). The poly (ester amide) was modified by reacting with 2, 4-diisocyanate under N2 atmosphere at 120oC to give poly (ester amide) urethane. Physicochemical characterization was carried out on both fatty amides, the unmodified and modified poly (ester amide). The film properties and chemical resistance were carried out on both the unmodified and urethane modified poly (ester amide). FTIR and TGA analysis were also carried out on the unmodified and the modified poly (ester amide). Findings revealed that the oil is semi-drying; suitable for surface coatings and that the performances of the poly (ester amide) were enhanced in terms of chemical resistance, film properties and thermal stability upon modification with a diisocyanate

Unlocking Full Economic Potential of Agriculture Sector in Punjab: Policy Options
Get PDFIn order to unlock the full economic potential of agriculture sector in Punjab, there is need to identify, map and prioritize the challenges and constraints faced by agriculture. The key challenges and constraints in the agricultural value chain from production to consumption include productivity, financing and regulatory. The policy initiatives are called to boost agricultural productivity, reduce post-harvest losses and expand market access. There is need for private investment in agribusiness value chain to lower cost of financing and increased agro-financing measured in terms of cost of capital (%) paid, number of loans and credit provision, private capital formation and number of participants. Private investment is essential for storage, processing, marketing and trade, and infrastructure. It is essential to develop and launch agro-entrepreneurship platforms for youth and women to enter agribusiness economy by facilitating investment support, training, and capacity building. The database for rural infrastructure planning is required to be revitalized for robust agriculture policy and planning. Climate smart agriculture calls for developing technical, policy and investment conditions to achieve sustainable agricultural development by sustainably increasing agricultural productivity and incomes, adapting and building resilience to climate change and reducing and/or removing greenhouse gases emissions
Socioeconomic Status of Local Communities and Their Relationship with Coastal Mangroves in Mirsarai, Chittagong, Bangladesh
Get PDFCoastal communities are mostly dependent on coastal resources for their social and economic needs. Mangroves are productive ecosystem with a complex interaction among people and resources. The present study was aimed to assess the socio-economic aspects of coastal communities who have been living within the boundary of Domkhali, Mogadia and Bamunsundor coastal villages at Mirsarai, Chittagong. In the three villages, 90 respondents (30 respondents from each village) were interviewed for primary data collection using a semi-structured questionnaire. From the study, it was observed that male and female respondents of age class (31-40 years) extracted maximum amount of resources having family size 5-7 numbers. Most of the respondents had no institutional education. The respondents who were engaged in fishing were the main extractor of resources (BDT 359035.3) followed by agriculture (BDT 231900), Businessman (BDT 109562.5), day labor (BDT 90800), housewife (BDT 80236.4) and others (BDT 100800). In this study, it was found that maximum 50% respondents in Domkhali got very low income of BDT < 10000 followed by Bamunsundor (30%) and Mogadia (20%). In three villages 93% household belonged to kacha house whereas only 7% was semi-pacca and not a single person had pacca house. Maximum respondents of Bamunsundor village (90%) had livestock followed by Mogadia (80%) and Domkhali (60%). When calculated the village wise resource extraction, it was found that maximum extracted resources were recorded in Domkhali (47%) followed by Mogadia (37%) and Bamunsundor (16%). This study suggested for creating the scope of higher education for the local residents who will be engaged in other professions avoiding much dependency of mangrove resources. Alternative income generating activities should be provided by government and NGOs for controlling the excessive resource collection ensuring social- economic and environmental balance
Universal Thesis of Meanders
Get PDFProposed is a universal thesis of meanders: In any flow, the main thread of flow that is the locus of the fastest fluid particle in each the cross-section governs the whole meandering of flow. The main thread of flow plays the critical role in meanders of flow in such a way that if there is any disturbance the main thread of flow, as well as the flow itself, meander under the condition that the system of the rest subordinate surrounding fluid particles including boundaries is unstable. The balance between the disturbing force and the restoring force maintains the meandering of flow
