Effect of phytase superdosing, myo-inositol and available phosphorus concentrations on performance and bone mineralisation in broilers

引用

Animal Nutrition 2017年第3期3卷 247-251页

作者： Sophie A.Lee Devanaboyina Nagalakshmi Mantina V.L.N.Raju Savaram V.rama rao Michael R.Bedford AB Vista Marlborough Department of Animal Nutrition College of Veterinary Science Dectorate of Poultry Research

A total of 2,376 one-day-old Ross broiler chickens were used to investigate the effect of myo-inositol(MYO) and phytase supplementation on performance and bone mineralization variables in broilers fed diets formulated to have varying concentrations of available phosphorus(P). The trial was designed as a2×2×3 factorial; with and without phytase superdosing(0 or 1,500 FTU/kg), MYO(0 or 3 g/kg), and dietary P(low, moderate or high). At 21 d, dietary phytase and MYO had no consistent benefit on bone mineralization variables. Bone ash reduced by 4.7% from the medium to low P diet(P < 0.01),with no effect of phytase supplementation. Superdosing improved bone P content by 6% in birds fed the low P diet, signifying an interaction between dietary P concentrations and phytase(P < 0.05). Dietary MYO addition resulted in a numerical reduction in bone ash and a significant reduction in bone strength(P < 0.05). At 42 d, the beneficial effect of phytase superdosing on feed intake and body weight gain was evident in the low P diet. Superdosing reduced feed conversion rate(FCR) at all P levels(P < 0.05),although this effect was more pronounced on the low P diet, suggesting that sufficient P being released from the phytase itself to re-phosphorylate MYO and hence improve FCR. The significant improvement in FCR was greater with superdosing than with MYO alone, and the combination led to no further improvement in FCR compared with superdosing alone, signifying a phytase and MYO interaction(P < 0.05). From these results, it can be estimated that MYO is providing around 30% to 35% of the total response to superdosing.

Microcontroller-Based Variable Speed Drive for Three-Phase Induction Motor in Cooling Applications

引用

Journal of Energy and Power Engineering 2012年第4期6卷 656-662页

作者： Kondapalli Siva rama rao Lee Teng Hong Department of Electrical and Electronics Engineering Universiti Teknologi PETRONAS Tronoh 31750 Malaysia

This paper presents an electronic VSD （variable speed drive） for three-phase IM （induction motor） using a microcontroller. The VSD is designed for cooling applications where the 1M is coupled to a cooling fan. The drive receives temperature feedback from objects to be cooled and output a corresponding frequency to the IM. A prototype of the VSD is constructed to control a 175 W, four pole, squirrel cage three-phase IM. The heart of the control circuit is a low-cost microchip＇s PICI6F777 microcontroller which is programmed using C language to generate variable frequency SPWM （sinusoidal pulse width modulation） switching signals. These switching signals are fed to an 1GBT inverter. The VSD constructed can be switched between two modes of speed control＂ automatic temperature-controlled mode and manual user-controlled mode. Cost savings using the prototype are demonstrated.

Fourth order differential equations are considered to develop the class of methods for the numerical solution of boundary value problems. In this paper, we have discussed the regions of absolute stability of fourth order boundary value problems. Methods proposed and derived in this paper are applied to solve a fourth-order boundary value problem. Numerical results are given to illustrate the efficiency of our methods and compared with exact solution.

通过催化化学气相沉积法合成了多壁碳纳米管(MW CNTs)。在相转移催化剂甲基三辛基氯化铵存在下,以高锰酸钾(KM nO4)为氧化剂在室温下对MW CNTs进行功能化处理。采用傅立叶变化红外光谱、热失重分析分析法对功能化MW CNTs进行表征。借助超声波降解法将功能化MW CNTs分散在二氯甲烷中形成悬浮液,然后将其悬浮液逐滴加至搅拌的聚乙烯醇溶液中形成海绵状微球。扫描电子显微镜(SEM)显示:形成的海绵状微球由松散缠结的MW CNTs构成,直径为50μm～150μm。该微球可望应用于轻型吸能涂料,催化剂以及电子学领域。

Particle Movement Using Monte-Carlo Technique in a Gas Insulated Busduct of Various Designs

引用

Journal of Energy and Power Engineering 2014年第8期8卷 1487-1493页

作者： Nagarjuna Reddy Poreddy Amarnath Jinka rama rao Narapareddy Department of EEE Kakatiya Institute of Technology & Science Waranga1506015 India Department of EEE JNTU College of Engineering Hyderabad 500085 India Department of EEE Sri Venkateswara College of Engineering Bangalore 560019 India

Due to the higher reliability and small ground space requirement, compressed GIS （gas insulated substation） has found extensive applications in urban areas and developing countries. The major parts of GIS is the gas insulated busducts, circuit breakers, isolators, etc.. The voltage withstand capability of SF6 （sulphur hexafluoride） busduct is strongly dependent on field perturbations such as those caused by conductor surface imperfections and by conducting particle contaminants which arise due to manufacturing process, mechanical vibrations, moving parts of system etc.. Contamination can create insulation problems at operating fields. An optimized design of GIS by varying the inner and outer diameter to 89 mm and 241 mm is considered for analysis and compared with a single phase enclosure with outer diameter as 152 mm and inner conductor diameter of 55 mm with aluminum and copper particles of size 10 mm in length and 0.25 mm in radius present on the enclosure. The results have been compared on the extent of particle movement for the same condition of the gas and particle geometry. Monte Carlo simulation is also carried out for determining the motion of particles in axial and radial directions. The random solid angle is changed from 1 to 0.5 degrees to take into account more smooth end profile of the particle. The simulation results have been presented and analyzed.

A Perceptual Approach to Reduce Musical Noise Using Critical Bands Tonality Coefficients and Masking Thresholds

引用

International Journal of Communications, Network and System Sciences 2009年第8期2卷 742-745页

作者： Ch. V. rama rao M. B. rama Murthy K. Srinivasa rao 不详

Traditional noise reduction techniques have the drawback of generating an annoying musical noise. A new scheme for speech enhancement in high noise environment is developed by considering human auditory system masking characteristics. The new scheme considers the masking threshold of both noisy speech and the denoised one, to detect musical noise components. To make them inaudible, they are set under the noise masking threshold. The improved signal is subjected to extensive subjective and objective tests. It is ob-served that the musical noise is appreciably reduced even at very low signal to noise ratios.
