Tholkappiyar's Latent Theory and Eighteen Lesser Texts

The Tamil language is divided into two dialects, the world dialect and the poetic dialect. All the words in this language have meanings. The subject will be explicit and specific. A series is made up of words. The phrase does not stand at its own point but expresses a different meaning. There is a lot of positive meaning in this way. They are referential interpretation in fewer places. Words and phrases convey meaning both at the internal and external levels. When it expresses external views, it is called referential and referential. In the case of the subject, the object of reference is indicated by two technical terms, latent and meat. Both are specific to internal songs. Scholars interpret these by citing the internal poems of the Sangam literature. Like the Sangam literature, the internal literature of the post-Sangam period occupies a special place. They are based on Kurinji and other tinais. This article is intended to examine the meaning of the poems from the point of view of the latent theories of Tolkappiar

Spectral fluctuation characterization of random matrix ensembles through wavelets

A recently developed wavelet based approach is employed to characterize the scaling behavior of spectral fluctuations of random matrix ensembles, as well as complex atomic systems. Our study clearly reveals anti-persistent behavior and supports the Fourier power spectral analysis. It also finds evidence for multi-fractal nature in the atomic spectra. The multi-resolution and localization nature of the discrete wavelets ideally characterizes the fluctuations in these time series, some of which are not stationary.Comment: 7 pages, 2 eps figure

A Note On Strongly Gorenstein X-Flat Modules

Mao and Ding introduced the concept of injective modules. D. Bennis and N. Mahdou introduced and studied the concept of strongly Gorenstein projective and injective modules. In this article, we have introduced and examined strongly Gorenstein-flat modules, which are the generalizations of strongly flat modules. Further, we have linked them with the strongly Gorenstein-projective module

Dezincification of Brass in Sulfide Polluted Sodium Chloride Medium: Evaluation of the Effectiveness of 2-Mercaptobenzothiazole

The present paper addresses the effectiveness of 2-mercaptobenzothiazole (MBT) in preventing the dezincification of brass in sulfide polluted 3.5% NaCl solution. The dezincification behaviour of brass in 3.5% NaCl solution containing 100-1000 ppm of sulfide ions and 1 x 10-6 to 1 x 10-3 M MBT was studied by potentiodynamic polarization, electrochemical impedance spectroscopy, current-time transient and accelerated leaching studies. The presence of sulfide ions in 3.5% NaCl solution has caused a significant increase in the extent of corrosion attack on brass. The inhibiting effect of MBT is markedly reduced in the presence of sulfide ions in the medium. The easy replacement of Cu-MBT complex by Cu2S film on the surface of brass is responsible for the inability of MBT to prevent corrosion attack in the presence of sulfide ions. The study concludes that the effectiveness of MBT in preventing the dezincification of brass is dependent on the concentration of the sulfide ions in the medium and the effectiveness is nullified at higher concentrations of sulfide ions

Stock assessment of seerfishes in the Indian seas

The annual average catch of seerfishes from the Indian seas was 45,0601 during 1995-'99, which constituted 1.8% of the total marine fish catch in India. State-wise Gujarat (28.5%) was the major producer followed by Tamilnadu (15.8%), Maharashtra (15.4%), Andhra Pradesh (11.4%) and Kerala (10.5%). Gill net is the dominant gear in exploiting seerfish followed by trawl, hooks & line, boat seines, shore seines and purse seines. Among the five species, the kingseer Scomberomorus commerson (59.0%) and the spotted seer S. guttatus (35.1%) sustained the fishery, while the streaked seer S.lineolatus and the wahoo Acanthocybium solandri formed only a negligible portion of the fisher

Status of exploitation of seerfishes in the Indian seas

Seerfish production from the Indian seas during the past five decades from 1950s to 1990s, showed an increasing trend. The annual catch increased from 4,505 t in 1953 to 54,8761 in 1998. The average annual catch during the five decadal periods k-aried from 7,278 t in 1950-'59 to 41,575 t in 1990-'99 contributing 1.5% and 1.75% respectively to the total marine fish catch of India. However, the rate of increase through the successive decades decreased indicating the attainment of op- ;imum level of production currently. During 1950-'59, the east coast contributed more (60%) than the west coast (40%), which changed to 36:64 during 1990-'99. iVmong the maritime states of India, Gujarat (25.88%), Maharashtra (16.09%), familnadu (13.59%), Kerala (13.07%) and Andhra Pradesh (12.68%) were the prime seerfish producers during 1990-'99. Gill net (64.8%) was the dominant gear, folowed by trawl (17.4%) and hooks and line (4%) with an average catch rate of 8.1 <g/unit, 0.24 kg/hr and 3.7 kg/unit respectively during 1995-'99. Among the five species, the fishery was sustained only by two species viz., the king seer Scomberomorus commerson and the spotted seer S.guttatus

Stock assessment of coastal tunas in the Indian seas

Tuna and billfish production from the Indian coastal waters, Lakshadweep and Andaman and Nicobar islands during the period 1985-'99 averaged 40,204 t. The contribution by E.affinis, Athazard, T.tonggol, K.pelamis and T.albacares (young ones) were 18,5041,6,8521,3,093 t, 3,3921 and 2,2111 respectively. Drift gill net was the major gear employed in the coastal tuna fishery. The length frequency data collected on the above species during 1990-'98 at seven centres along the Indian coast were analysed employing FiSAT programme to estimate their growth and mortality parameters, exploitation rates and relative yield per recmit
