Agriculture and the theory of industrialization in the Thoorvai novel

Advancement of agriculture with reference to the novel “Thoorvai” Indian economy mostly dependent on Agriculture. She slighted charge is the agriculture will affect other sectors dramatically. India is the second most populous nation, First in millet production, second in wheat and paddy production and comes third in coconut production. For highly populated nations like India, a focus an agriculture is necessary to maintain food safety. Without receiving enough compensation, farmers from earlier generations are less likely to allow their forebears to participate in agriculturem, which results in a decline in agricultural activity this research

A Study of the Techniques of Poet Vairamuthu’s Film Songs

The poets use various techniques in the song to reach out to the people with ease of conveying the idea that has arisen in their hearts. Lyricists are structured to renew themselves each time with the ideas and ideas of the times. Lyricists use strategies to establish themselves and identify themselves uniquely. The main aim of the technique is to inculcate the idea in the minds of the listeners of the song. Strategy plays an important role in beautification in films with many changes over time. In some songs, the method of delivery is better than the content. Ka Pa Aravaanan says, "The content of creation is like the body. But the mode of realization is like life." Poet Vairamuthu has used techniques to improve the quality of his songs as well as to simply convey his point of view. It is evident from his songs that he has employed techniques in his songs to convey the literary influence of Sangam literature, epics, moral stories, legends, epics, etc., to the people

Synthesis And Characterization Of Undoped And Co-Doped SnO2 Nanoparticles

Undoped and Co-doped (1 and 3 at. %) SnO2 nanoparticles were synthesized by a simple co-precipitation method. X-Ray diffraction data revealed that both undoped and doped samples crystallize in the tetragonal rutile phase with CoO phase in doped samples. The lattice parameters of doped samples calculated from XRD data do not vary much when compared to undoped one indicating that Co has not substituted the host lattice. The surface morphology investigated by SEM indicates the cluster formation in Co-doped (1 and 3 at. %) nanoparticles and the chemical composition of the samples were analyzed by energy dispersive spectroscopy (EDS). UV-Vis spectrum of undoped system showed absorption at 408 nm (3.04 eV), which is red shifted by 0.56 eV compared to bulk SnO2 (3.6 eV) due to the cluster nature of the sample. The UV-Vis spectra of doped samples showed absorption in the visible region due to the formation of CoO phase, which is also evident from the XRD spectra. PL spectra showed characteristic UV emission at 409 nm and blue emission at 480 nm. The characteristic vibrational modes of SnO2 were studied from FTIR analysis. EPR measurement of Co-doped (3 at .%) SnO2 nanoparticles showed the paramagnetic behavior which may be attributed to the occupation of Co2+ ions in the interstitial site rather than the substitutional site. The absence of ferromagnetism is due to the high doping concentration of Co (> 1 at. %) and also due to the high annealing temperature which destroys the hyperfine splitting.

Multiple Bandwidth FIR Filter Design with Adaptive Algorithms for Hearing Aid Systems

605-623Digital Filter design plays a vital role in signal processing and communication applications. This paper proposes a hearing loss system model with Variable Bandwidth FIR Filter (VBF) and adaptive algorithms for the application to listening. The tunable band filter is designed to provide an appropriate sound level. This filter has several sub-filters each of which is designed with set of selected bandwidths. The sub-bands obtained are adjusted with proper magnitude by trial and error method. Algorithms such as Least Mean Square (LMS), Normalized Least Mean Square (NLMS) and Recursive Least Squares (RLS) are incorporated to improve the quality of the signal. The filter thus designed is examined by taking a number of audio signals. The tests on various hearing loss cases with different type of input signal suggest that this method is capable of reproducing a signal which sounds exactly the same as the original signal. The multiple bandwidth filters is analyzed with mild, moderate, profound and severe hearing loss patterns and the results are reported. The matching error is calculated between ideal response and actual response. The result show that the designed filter provides acceptable minimum matching error and it lies in the range 0 to 2.5dB.This filter design is implemented in TMS320C6711 processor and is tested for sinusoidal input signal

A Study of Family Relationships in Film Songs by Poet Vairamuthu

A single tree is not a grove. Similarly, the life of the individual is not special. Family structures pave the way for the discipline of individual life in the social system. A country without a family structure and a house are the same as a boat without a fin. Today, family systems are the maturity of man's high cultural evolution. Family gives us rich structures of tradition and culture. The family system has passed through thousands of years. When a man is born, his mother and father, and his way of life are naturally established for them. When they get married, they join new relationships along the way. The family structure is formed from the expansion of the relative circle when children are born. Today, human life of the development of science and science is hampered by coarse cultural practices that derail the course of our lives. Vairamuthu's songs are a reminder of the value of relationships for the present generation who forget relationships and move towards the economy

Peanut shaped ZnO microstructures: controlled synthesis and nucleation growth toward low-cost dye sensitized solar cells

International audienceThis paper describes a simple, low-temperature and cost effective chemical precipitation method in aqueous media to synthesis uniformly distributed zinc oxide (ZnO) microstructures for the fabrication of dye-sensitized solar cells (DSSCs). The size and morphology of the ZnO microstructures are systematically controlled by adjusting the concentration of the precursors, zinc acetate dihydrate and ammonium hydroxide. X-ray diffraction (XRD) and scanning electron microscopy (SEM) are used for the structural characterizations and photoluminescence and Fourier transform infrared spectroscopy are used to characterize the optical properties of the ZnO, respectively. The results reveal that ZnO crystallites exhibit hexagonal wurtzite structure with preferential orientation along c-axis. The effect of ammonia concentration on the crystallinity, morphology and optical properties of ZnO microstructures and the concomitant effect on the efficiency of dye-sensitized solar cells is also quantified. The peanut-shaped ZnO microstructure, which was found to increase DSSCs performance over other microstructure, is studied in detail in order to develop a formation mechanism. A sandwich type eosin yellow sensitized solar cell is prepared using peanut-shaped ZnO microstructures, which showed an efficiency of 0.37%. Ammonia was found to play a crucial role in the evolution of ZnO morphologies. These results are promising and provide a path towards low-cost high-performance DSSCs based on peanut-shaped ZnO microstructures and produced with only relatively simple wet chemistry synthesis
