J.M. Nallasamy Pillai’s Magazine “Siddhanta Deepikai” Study Summary

Newspapers are the primary means in giving information to the people. Newsapapers contains various types of publications such as daily, weekly and monthly. The present era which is excellent in information technology, publishes many magazines with various innovations throughout world in different languages. In Tamil Nadu, many magazines have been published in many languages including English, Telugu, Malayalam, etc. Political Magazines, Medical Magazines, Religious Magazines, Literary Magazines, Sports Magazines are also published. In the history of Tamil journalism, there are many magazines that have been published continuously since its inception, there are magazines that have been re- published after a hiatus, and magazines that have not been published again after a hiatus. Among them J.M. Nallasamy Pillai’s “Siddhanta Deepikai” was a magazine of Saivism and Tamil literature that began in the late nineteenth and early twentieth centuries. Siddhantha Deepika magazine which was published in Tamil as “Siddhanta Deepika” and in English as “The Siddhanta Deepika or The Light of Truth”. The purpose of this article is to briefly explore about Nallasamy Pillai. This article follows both historical research and evaluation research

A unified learning framework for content based medical image retrieval using a statistical model

AbstractThis paper presents a unified learning framework for heterogeneous medical image retrieval based on a Full Range Autoregressive Model (FRAR) with the Bayesian approach (BA). Using the unified framework, the color autocorrelogram, edge orientation autocorrelogram (EOAC) and micro-texture information of medical images are extracted. The EOAC is constructed in HSV color space, to circumvent the loss of edges due to spectral and chromatic variations. The proposed system employed adaptive binary tree based support vector machine (ABTSVM) for efficient and fast classification of medical images in feature vector space. The Manhattan distance measure of order one is used in the proposed system to perform a similarity measure in the classified and indexed feature vector space. The precision and recall (PR) method is used as a measure of performance in the proposed system. Short-term based relevance feedback (RF) mechanism is also adopted to reduce the semantic gap. The Experimental results reveal that the retrieval performance of the proposed system for heterogeneous medical image database is better than the existing systems at low computational and storage cost

Evolutionary dynamics on strongly correlated fitness landscapes

We study the evolutionary dynamics of a maladapted population of self-replicating sequences on strongly correlated fitness landscapes. Each sequence is assumed to be composed of blocks of equal length and its fitness is given by a linear combination of four independent block fitnesses. A mutation affects the fitness contribution of a single block leaving the other blocks unchanged and hence inducing correlations between the parent and mutant fitness. On such strongly correlated fitness landscapes, we calculate the dynamical properties like the number of jumps in the most populated sequence and the temporal distribution of the last jump which is shown to exhibit a inverse square dependence as in evolution on uncorrelated fitness landscapes. We also obtain exact results for the distribution of records and extremes for correlated random variables

Indices and fecundity of a threatened freshwater catfish Mystus montanus

Fecundity of threatened catfish Mystus montanus was estimated from a collection of gravid females, which ranged from 290 to 27,972 according to body length and weight. The relationship between fecundity and BL, BW, GL and GW was analyzed by linear regression, which showed both positive and negative correlation. Gonado-somatic index (GSI), hepato-somatic index (HSI) and spleen-somatic index (SSI) ranged from 0.135 to 21.28, 0.358 to 21.33 and 0.126 to 1.08 in females and the corresponding values for males were 0.17 to 10.68, 0.619 to 3.25 and 1.25 to 2.33 respectively

Number of adaptive steps to a local fitness peak

We consider a population of genotype sequences evolving on a rugged fitness landscape with many local fitness peaks. The population walks uphill until it encounters a local fitness maximum. We find that the statistical properties of the walk length depend on whether the underlying fitness distribution has a finite mean. If the mean is finite, all the walk length cumulants grow with the sequence length but approach a constant otherwise. Experimental implications of our analytical results are also discussed

Production of Diamino propionic acid ammonia lyase by a new strain of Salmonella typhimurium PU011

BACKGROUND: Seeds of the legume plant Lathyrus sativus, which is grown in arid and semi arid tropical regions, contain Diamino Propionic acid (DAP). DAP is a neurotoxin, which, when consumed, causes a disease called Lathyrism. Lathryrism may manifest as Neurolathyrism or Osteolathyrism, in which the nervous system, and bone formation respectively, are affected. DAP ammonia lyase is produced by a few microorganisms such as Salmonella typhi, Salmonella typhimurium and Pseudomonas, and is capable of detoxifying DAP. RESULTS: S. typhimurium PU011, a non-virulent bacterial strain isolated in our lab, was found to produce DAP ammonia lyase enzyme when grown in minimal medium containing DAP. There was a direct correlation between biomass yield and enzyme activity, until 16 h post inoculation in minimal medium containing DAP. Following ammonium sulphate precipitation and passing through Sephadex G100, CM-Sephadex and DEAE-Sephacel for crude enzyme extract preparation, about 68-fold enzyme purity was obtained. The purified enzyme gave maximum activity at pH 8.0 and was stable up to 45 degrees C. The Km value for the substrate was found to be 0.685mM, calculated from a Line Weaver Burk plot. CONCLUSION: A new bacterial strain, S.typhimurium PU 011, which is capable of producing DAP ammonia lyase, was isolated

Gamma Radiation influence on Growth, Biochemical and Yield Characters of Cajanus cajan (L.) Millsp.

The present investigation deals with the effect of gamma radiation on growth, Biochemical and yield traits of Pigeon pea. The seeds of Pigeon pea Var.CO-7 were treated with different doses of gamma rays like 15, 20 and 25KR. The treated seeds were sown in field along with control to raise M1 generation and the radiation effects was noted from seed germination percentage, seedling survival (%), seedling height on 30th days, Days to first flower, plant height, (at maturity), number of branches, number  of leaves, number of cluster, pollen viability (%), number of pods, seed yield, hundred seed weight (g), fresh and dry weight (g), Seed viability (%) and seed protein content (%). The results indicates that the growth, biochemical and yield parameters were gradually decreased when compare to control and the highest reduction was noted at higher doses of gamma radiation treatments. The pollen and seed viability (%) analysis were also reveled that gradually reduction in lower to higher doses of gamma rays treatments

Managing Class II Malocclusion Using Twin Block Therapy in a Young Adolescent male: A Case report

Patients with untapped development potential benefit greatly from twin block therapy. However, a variety of patient-related characteristics, including age, gender, patient compliance, and other arbitrary criteria, complicate its effective application. Orthopaedics and growth modification can use the right forces to repair the malocclusion if given the proper care in a timely manner. When a patient has a retruded mandible and is presenting with a positive visual treatment objective, the appliance is quite effective. In this work, a successful skeletal alteration is described in the instance of a male patient, age 11, who had the typical twin block appliance indication
