Influence of Different Irrigation Regimes on the Phenology and Accumulated Heat Units in Four Bread Wheat Cultivars
M.Z. Alam,S.A. Haider,N.K. Paul
Pakistan Journal of Biological Sciences , 2004,
Abstract: A field investigation was carried out to study the influence of irrigation on phenology and accumulated heat units of four cultivars of bread wheat (Triticum aestivum L.) at different phenological stages over two growing seasons. There were three treatments: rainfed, 10 and 20 mm irrigation. The rainfed plants had significantly shorter phenological stages and lower growing day degree than the irrigated plants in all the four cultivars. Cultivars Akbar was found to be early and C 306 was found to be late maturing. Akbar had the lowest and C 306 had the highest growing degree days during all the phenological stages under each irrigation regime. Heliothermal units also showed more or less the same trends. The phenothermal indices and heat use efficiency were found to be higher in the irrigated plants than the rainfed plants.

Journal of Biological Sciences , 2003,
Abstract: A field investigation was carried out to study the influence of sowing dates on phenology and accumulated heat units of four cultivars of bread wheat (Triticum aestivum L.) at different phenological stages over two growing seasons. There were two sowing dates: early and late. The late sown plants had significantly shorter phenological stages and lower growing day degree than the early sown plants in all the four cultivars. Cultivars Akbar was found to be early and C 306 was found to be late maturing. Akbar had the lowest and C 306 had the highest growing degree days during all the phenological stages under each irrigation regimes. Heliothermal units also showed more or less the same trends. The phenothermal indices and heat use efficiency were found to be higher in the early sown plants than the late sown plants.

Nanocomposite coatings based on Ti-N-Cr/Ni-Cr-B-Si-Fe, gained by two technologies
N.K. Erdybayeva
Journal of Nano- and Electronic Physics , 2009,
Abstract: The first results of manufacturing and investigations of a new type of nanocomposite protective coatings are presented. They were manufactured using a combination of two technologies: plasma-detonation coating deposition with the help of plasma jets and thin coating vacuum-arc deposition. We investigated structure, morphology, physical and mechanical properties of the coatings of 80-90 μm thickness, as well as defined the hardness, elastic Young modulus and their corrosion resistance in different media. Grain dimensions of the nanocomposite coatings on Ti-N-Cr base varied from 2.8 to 4 nm. The following phases and compounds formed as a result of plasma interaction with the thick coating surface were found in the coatings: Ti-N-Cr (200), (220), y-Ni3-Fe, a hexagonal Cr2-Ti, Fe3-Ni, (Fe, Ni)N and the following Ti-Ni compounds: Ti2Ni, Ni3Ti, Ni4Ti, etc. We also found that the nanocomposite coating microhardness increased to H = 31.6 ± 1.1 GPa. The Young elastic modulus was determined to be E = 319 ± 27 GPa – it was derived from the loading-unloading curves. The protective coating demonstrated the increased corrosion resistance in acidic and alkaline media in comparison with that of the stainless steel substrate.
Software as A Service: Analysis of ‘Google Sites’ as KM Tool for Academic Environment
Farooqui N.K.
Communications of the IBIMA , 2008,
Abstract: This paper analyzes different factors related with a newly launched ‘Google Sites for suitability as the knowledge management tool in academic environment. The cost of software purchase and its maintenance is a big issue for academic and business world. The emergence of high speed Internet has given rise to new concepts like software as a service. SaaS (Software as a Service) has a new way out, the software is made and maintained by the software firm and used by the organization (Educational / Business). If the software is provided by the Google then it is double benefit for any organization. Paper discusses different factors like privacy, scalability, support, Technology, ease of use, provision of essential services, Internal communication facilities, searching capability, accessibility, control and administration, licensing location & management and Cost of 'Google Sites' for implementing it as a KM tool in academic environment.
Empirical Computation Of Rs-Analysis For Building Robust Steganography Using Integer Wavelet Transform And Genetic Algorithm
Shamimunnisabi, Cauvery N.K
International Journal of Engineering Trends and Technology , 2012,
Abstract: The proposed system presents a novel approach of building a secure data hiding technique of Steganography using Integer Wavelet Transform along with Genetic Algorithm. The prominent focus of the proposed work is to develop Resistant Secure-analysis proof design with highest imperceptibility. Optimal Pixel Adjustment Process is also adopted to minimize the difference error between the input cover image and the embeddedimage and in order to maximize the hiding capacity with low distortions respectively. The analysis is done for mapping function, Peak Signal to Noise Ratio, image histogram, and parameters of RS analysis. The implementation results highlights that the proposed security measure basically gives better and optimal results in comparison to prior research work conducted using wavelets and Genetic Algorithm
Determination of Di-n-Butyl Phosphate in Organic Streams of FBTR Mixed Carbide Fuel Reprocessing Solution by Gas Chromatographic Technique  [PDF]
P. Velavendan, S. Ganesh, N.K. Pandey, U. Kamachi Mudali, R. Natarajan
Journal of Analytical Sciences, Methods and Instrumentation (JASMI) , 2011, DOI: 10.4236/jasmi.2011.12005
Abstract: The present work describes the amount of Di-n- butyl phosphate (DBP) produced when PUREX solvent (30%tri-n-butyl phosphate (TBP) mixed with 70% hydrocarbon diluent) is exposed to intensive radiolytic and chemical at- tack during the separation of uranium and plutonium from fission products of FBTR mixed carbide fuel reprocessing solution. DBP is the major degradation product of Tri-n-butyl phosphate (TBP). Amount of DBP formed in the lean organic streams of different fuel burn-up FBTR carbide fuel reprocessing solutions were analyzed by Gas Chromatographic technique. The method is based on the preparation of diazo methane and conversion of non-volatile Di-n-butyl phosphate in to volatile and stable derivatives by the action of diazomethane and then determined by Gas Chromatography (GC). A calibration graph was made for DBP over a concentration in the range from 200 to 1800 ppm with correlation coefficient of 0.99587 and RSD 1.2%. The degraded 30% TBP-NPH solvent loaded with heavy metal ions like uranium was analyzed after repeated use and results are compared with standard ion chromatographic technique. A column comparison study to select of proper gas chromatographic column for the separation of DBP from other components in a single aliquot of injection is also examined.
Comparison of BER of OFDM System using QPSK and 16QAM over Multipath Rayleigh Fading Channel using Pilot-Based Channel Estimation
Sanjay Khadagade,N.K.Mittal
International Journal of Engineering and Advanced Technology , 2013,
Abstract: This paper investigate and compare the various channel estimation techniques based on pilot arrangement with the communication system that uses QPSK and 16-QAM to transmit information using OFDM over multipath Rayleigh fading channel. Bit Error Rate (BER) has been considered as the performance index in all analysis. In the block type pilot arrangement, the performance of channel estimation is analyzed with three different algorithms: LS, LMMSE and SVD algorithm. In comb type pilot arrangement, the paper introduces three method of interpolation: linear interpolation, second order interpolation and cubic spline interpolation for channel estimation. The analysis has been carried out with simulation studies under MATLAB environment.
