Experimental and theoretical investigation of Gabapentin by Density functional theory[ ]


The FT-IR and FT-Raman spectra of Gabapentin (GBT) have been recorded in the region 4000–400 and 3500–100 cm-1 respectively. The optimized geometry, frequency and intensity of the vibrational bands were obtained by the density functional theory (DFT) using 6-31G(d,p) basis set. The harmonic vibrational frequencies were scaled and compared with experimental values. The observed and the calculated frequencies were found to be in good agreement. The UV–visible spectrum was also recorded and compared with the theoretical values. The calculated HOMO and LUMO energies show that charge transfer occurs within the molecule. The Mulliken charges of the molecule were also computed using DFT calculations. Stability of the molecule arising from hyper conjugative interactions, charge delocalization were analyzed using natural bond orbital (NBO) analysis. Information about the charge density distribution of the molecule and its chemical reactivity were obtained by mapping molecular electrostatic potential surface. In addition, the non-linear optical properties were discussed from the dipole moment values and the excitation wavelength in the UV–visible region.

Electricity Load Forecasting in Imo State Using Soft Computing Techniques[ ]


This paper presents electricity load forecast of Imo state Nigeria using fuzzy logic soft computing technique. Historical load data from Enugu Electricity Distribution Company (EEDC) Owerri, combined with hourly weather data from the online weather portal “www.wunderground.com/q/zmw:0000.3.WDNIM” were used for training and testing the fuzzy inference system (FIS). The inputs to the FIS are the hour-by-hour weather (temperature and humidity) for the forecast month (august 2015) and the mean of the previous similar day load (preload) data for August 2013 and August 2014 (2 months). The output is the forecasted load for the month of August 2015. The load data are influenced by variances in day types, namely the weekdays and weekends hence each of these day types has different load curve. Rules are developed for the FIS using the input data combined with the heuristic knowledge of the factors affecting the load (load driving parameters). Successful implementation and integration of the various stages of the testing, training and validation of the fuzzy logic system produced the complete, functional FIS model with a mean absolute percentage error (MAPE) of 0.8641%. The mean accuracy of the entire forecast result was 99.13%. The analysis shows satisfactory level of accuracy with regards to the FIS-based soft computing technique developed in forecasting future load demand of Imo state.

Evaluating the Role of Natural Resources in Sustainable Development in Babil Governorate, Iraq by using GIS and Remote Sensing[ ]


Babil governorate is one of the most important agricultural areas in Iraq. However, these areas began to deteriorate due to several reasons, including the economic sanctions, lack of governmental support to farmers, shortage in water resources and salinization. The main objectives of this study were to provide an accurate assessment of the agricultural areas in Babil governorate from 1985 to 2015 and to evaluate degradation due to soil salinity. This is to help in the development of land resources and their sustainability. Accordingly, Landsat images were acquired in 1985 (TM), 1999 ETM+), and 2015 (OLI-TIRS) and used in this study. Also, three vegetation indices (NDVI, TNDVI and SAVI) and two salinity indices (NDSI and SI) were used for the assessment of agricultural lands and salt-affected soils in the studied area. The obtained results indicated that agricultural areas were significantly decreased in the studied area from 1985 to 2015 based on the three studied vegetation indices. Agricultural areas were about 2644, 1508 and 2217 km2 in 1985, 1999 and 2015, respectively. This is based on the SAVI index, which had the highest accuracy when compared with the two other indices. On the other hand, the areas of salt-affected soils were significantly increased from 1985 to 2015 based on the NDSI and the SI indices. These areas were about 203, 446 and 371 km2 in 1985, 1999 and 2015, respectively. This is based on the SI index, which was more accurate than the NDSI.In conclusion serious strategies should be considered toward increasing land reclamation projects and sustainability of land resources against degradation.

Design of Robust Power System Stabilizer for Interconnected System[ ]


Electrical Power System is one of the most complex real time operating systems. It is probably one of the best examples of a large interconnected non-linear system of varying nature. This system changes it's state time to time with change in load, transmission and generation conditions. Such changes in the system causes small signal oscillations, the frequency range of such oscillations is about 0.2 to 3 Hz, if they are persist for long duration they may limiting the power transfer capability of the system. For the stable and secure operation of the system adequate damping for small signal oscillations is required. A auxiliary controller can provide adequate damping for the system called power system stabilizer (PSS).

A Review Regarding Quasar , Black Hole And Dark Matter . Quasar ( AGN ) Powered With Black Hole and with Dark Matter form Galaxy structure (rotational velocity curve ) is Inconsistent In Nature[ ]


It is being believed that quasars are central region of AGN and it is powered with black hole can only be resolved by making of new model of universe i.e. Hoyle – Narlikar universe and understanding DM and DE of the universe and finally understanding cause of rotational velocities of stars of galaxies . Black Holes are not the phenomenon of expansion phase of the universe rather it is the phenomenon of destruction phase of the universe when quasars ( white holes) would transform into black hole and it would engulf all the created Hot matter ( not Cold matter forming CDM Layer made up of Hyperons ) and all would transform into tachyons and the universe would be in symmetry phase again . Thus no bright galaxy is equipped with black hole and quasar neither in expansion phase nor in destruction phase . Therefore , all galaxies have rotational velocities of stars as designed by mind ( inner ascending curve and outer flat curve ) of central disc ( M1) and rotating stars (M2) .

Effect of Soil Type and Water Content on Rosemary Growth and Essential Oil Yield[ ]


This study aimed to investigate the effect of two types of soil: sandy clay (SC) and sandy loam (SL) and two irrigation systems: once (I1) and twice (I2) per week, with each soil, on the growth criteria and productivity of essential oil (EO) in rosemary (Rosmarinus officinalis L.) during two cuts at February and August (3, 9 months from transplanting, respectively). Cultivation in SL soil and I2 irrigation system, followed by SL and I1, significantly increased the growth characters as well as the yield of EO of rosemary plants during the two cuttings, as compared to those in corresponding plants cultivated in the SC soil. With all treatments, the above mentioned parameters were generally higher at the 2nd cut, compared to those at the 1st cut. In the SC soil, I1 irrigation system was more effective than I2 irrigation with respect to the vegetative growth rate at the first cut, whereas the reverse was obtained at the second cut. Within the different treatments, the enhancement of plant growth was generally proportional with the increase in leaf area and chlorophyll contents, whereas a negative correlation was observed between the carotenoid contents and soil moisture. Generally, planting in the SL soil concomitant with I1and I2 irrigation, effectively increased the oil yield (% and l/fed) during the two cuttings, compared to corresponding plants grown in the SC soil. In conclusion, rosemary plants could maximize the growth characters and EO content in sandy loam habitat combined with I2 irrigation, Irrespective of the applied treatment. The productivity of EO was higher at the second cut than the first one.

Seismic Sequence Stratigraphy and Structural Trends of the Clastic Deposits in Parts of Niger Delta, Nigeria[ ]


Despite several exploration and exploitation activities in the Niger Delta basin of Nigeria, a clearer understanding of depositional styles and reservoir characteristics of some of its deposits are still elusive. A three–dimensional (3D) seismic data and well log suites from two oil fields (Onshore Field A, and Offshore Field B) were therefore obtained and analyzed with Petrel software in order to examine depositional styles, dominant structures and stratigraphy of the deposits. A total of five faults and two horizons that indicated faulted anticlinal closures were closely observed in the Onshore Field A, while about twenty five faults were observed in the Offshore Field B. The inferred depositional environments of sediments in the basin consist of shelf, slope and deep basin settings. The deep basin settings are mainly dominated by submarine canyons and channel-levee systems whose deposits appear on seismic records as layered and chaotic facies. The channel-levee systems are interpreted as turbidites, distributary channel complexes, crevasse splays, hemi pelagic deposits as well as chaotic slump and debris flow deposits. The generated based on the 3D seismic data revealed that the stratigraphic architecture of deposits in the basin was controlled by variable subsidence.

Wall loss dependence on strained FBG sensors’ simulated response[ ]


Pressure vessels including pressurized pipes in the oil and gas industry are all subject to sustained load cracking and material wall loss. Constantly monitoring material wall losses at early stages is essential to the oil and gas industry. In this paper, a model of pressure wall thinning using combined FBG (Fiber Bragg Grating) sensors is presented. The simplistic model design make use of three FBG sensors, two dedicated to axial and hoop strain measurements, while the other sensor served for temperature compensation. Stress and strain simulations obtained for 1 to 5 MPa inner pipe pressures are used to identify the positions in elbows corresponding to maximum wall loss. Simulation of FBG’s optical spectrum reflectivity shows a wavelength shift directly related to the thickness of the pipe material.
