India and the International atomic energy agency

India is one of the founder members of the International Atomic Energy Agency. The sustained growth of its nuclear programme has accorded a unique distinction to India of being a developing country with strong foundations in advanced nuclear technology. This perspective of being a technologically advanced developing country has guided many of India's interactions on the IAEA platform

Social Thoughts of the Poet Snehan

The definition of renewal poetry is different today, but renewal poetry is intended as a poetic tradition, a poetic system devoid of grammar. The genealogy is to be found with the restrictions of the syllable, the thigh, the foot, the thigh, and the renewal is seen with a new look as if it had been cast out. The scene seen in the novels is universally accepted as having a realistic lyricism and sense of humor with simple Tamil words as it is without rhetorical words, and female poets and males use simple words with low footnotes to point out their experiences and social disorders. In the poems of the poet Snehan, who is a guide for today's younger generation, this essay expresses his social thoughts on language, patriotism, the sanctity of women, the purity of friendship and many more from his point of view

Review of the Indian oil sardine fishery

It is well known that the European and American herring, pilchard, sardine, etc., make the largest contribution to the fisheries of the world, and are the mainstay of the economy of most of the European maritime nations. The French expression 'la crise sardiniere' is a measure of the disastrous effect of the failure of the fishery to the nation

Role of high resolution computed tomography in the clinico- radiological study of diffuse parenchymal lung diseases and in disease progression of tuberculosis

Background: This study was undertaken to detect and study the various HRCT patterns of DPLD, to assess disease progression of TB, also to evaluate disease prognosis and reversibility by quantification of data and compare it with clinical and functional impairment as evaluated by PFT; and to finally correlate it with a histopathological diagnosis wherever necessary.Methods: This prospective study was conducted in the Department of Radiodiagnosis, SLIMS from December 2014 to November 2016. Patients of all age groups (3-86 years) presenting with dyspnea at rest/exertion, dry cough and known cases of DPLD were included; known lung anomalies were excluded. Clinical history with relevant lab investigations was followed by computerized radiography and HRCT. The extent of disease on HRCT scans, assessed by the mean attenuation value of the lung, was correlated with the severity of dyspnea and PFT results. HPE was done for diagnostic confirmation.Results: IPF including chronic interstitial pneumonia comprised the most common group of diseases accounting for 28.3% cases followed by TB (25%). ‘Tree in bud’ appearance (71.4%), consolidation (42.8%) and scattered nodules (28.5%) are features of active disease while fibrosis (50%), honeycombing (50%), traction bronchiectasis (37.5%) and calcified granuloma (37.5%) are features of inactive disease. The histogram of the relative frequency of pulmonary attenuation values was depressed and skewed to the right in most cases. There was a statistically significant positive correlation between the mean lung density and severity of dyspnea and the extent of functional impairment as measured by the reduction in DLCO. Seven cases of active TB, three of sarcoidosis, three of PSS and two each of ABPA and HP among others were biopsy proven.Conclusions: The present study concludes that HRCT is an invaluable tool in the detection, characterization, diagnosis, and evaluation of disease prognosis and reversibility of DPLDs especially in the study of disease progression of TB, in an appropriate clinical setting; while HPE is the gold standard for confirmation of the diagnosis

Nonlinear Control of pH System for Change Over Titration Curve

Wiener model based nonlinear controller for a pH process efficiently tackles the variations in gain. However, the controller performance deteriorates for significant change over titration curve (i.e. when the nature of the feed stream switches from a weak acid to a strong acid). To improve the performance of this controller, a nonlinear cascade controller is proposed. The nonlinear cascade structure consists of a Wiener model based nonlinear P controller in the inner loop and a linear PI controller in the outer loop. The proposed strategy is simulated for switch over titration curve from a weak acid – strong base system to strong acid – strong base system and then back to the weak acid – strong base system. The performance of the nonlinear cascade controller is compared with that of single loop Wiener model based PI controller and linear cascade (P-PI) controller
