Marketing Behaviour of Jasmine Growers
No full textThe present study was conducted in select villages of Tirunelveli district of Tamil
Nadu in order to know the marketing behaviour of jasmine growers with a sample size of 120 respondents. The respondents were selected based on proportionate random sampling method. The results of the study revealed that majority of the jasmine growers were using polythene bags for packing the produce and sold their produce through commission agents. More than two - fifths sold their produce in the villages. Majority of the respondents considered ‘immediate payment’ as the main criterion for the selection of market. Majority of the respondents had reported that they were not having sufficient marketing facility
Aspecten van het meten aan en het modelleren van het semi-quaternaire systeem NH3-CO2-H2O-ureum
No full textIn het verleden is in delft veel onderzoek 3an de fasenevenwichten in het systeem nh3 -c0z-hz0-(ureum) verricht en aan de beschrijving van deze fasenevenwichten. Het bovenstaande semi-quaternaire systeem is tot nu toe tot een druk van 20 bar en een temperatuur van 130 °c met behulp van een electrolyt-model beschreven. Om de modellering uit te breiden is bet noodzakelijk dat evenwichtsmetingen warden uitgevoerd bij drukken van 30 tot 60 bar en temperaturen van 130 tot 160 °c. Het doel van bet afstudeerwerk kan als volgt worden geformuleerd: - het operationeel maken van de bestaande apparatuur voor het uitvoeren van metingen aan het systeem nh3-co2-h20. - het verbeteren van de beschrijving van de vloeistof-damp evenwichten zoals door ramasamy voorgesteld. De experimentele apparatuur is gereed gemaakt voor bet uitvoeren van het gewenste onderzoek. In tegenstelling tot Ramasamy zullen de metingen bij alleen constante temperatuur warden uitgevoerd. Mede om datainterpolatie mogelijk te maken moet warden uitgegaan van het binaire ammoniak-water mengsel, waaraan in stappen kleine hoeveelheden kooldioxide warden toegevoegd. Tevens is een wijziging van de analysemethode van de vloeistoffase noodzakelijk om de monstergrootte te beperken. Een mogelijkheid hiertoe is de gaschromatografiscbe analyse van de vloeistoffase. Wat betreft de chromatografische analyse van de gasfase kan warden opgemerkt dat de analyse niet optimaal is door onvolledige scheiding van de componenten NH3 en CO2 door de tot nu toe gebruikte kolommen. Verwacht wordt dat een kolom met een belading van 15 % aan amines beter voldoet. De beschrijving van het systeem NH3-CO2-H2O met het uitgebreide Pitzer-model voor de vloeistoffase en de toestandsvergelijking van Nakamura voor de gasfase is door wijzigingen in de computerprogrammatuur verbeterd. Desondanks de verbeteringen is de beschrijving nog niet optimaal. Verdere verbeteringen zouden verkregen kunnen worden door reductie van het aantal geoptimaliseerde parameters, aanpassing van het aantal gebruikte interactieparameters , het integreren van parameters uit binaire metingen in de beschrijving van het ternaire systeem en het gebruik van optimale parameters voor de toestandsvergelijking van Nakamura.Applied Science
Clinical profile of cerebral venous thrombosis in pregnancy and puerperium in South India
No full textBackground: Cerebral venous thrombosis (CVT) is any thrombosis occurring in intracranial veins and sinuses, which is a rare disorder affecting 5 persons per million per year with huge regional variation. Pregnancy and puerperium are the most prevalent prothrombotic states leading to cerebral venous thrombosis. The objective of this study was to analysis the clinical profile of CVT in pregnancy and puerperium.Methods: In this prospective study, we analysed 52 consecutive patients admitted with impairment of consciousness, seizures or focal neurological deficit at our hospital. The diagnosis of CVT was confirmed by neuroimaging. Detailed history, clinical examination and laboratory investigations were carried out in all the cases and analysed.Results: The incidence of CVT associated with pregnancy and puerperium at our Hospital was 3.9 per 1000 obstetric admissions. The age of the patients varied from 18-35 years with a maximum age incidence (77%) in the III decade (21-30 years). The maximum incidence was during the first two weeks of puerperium (61.8%). The most common presenting symptoms were focal or generalised seizures (88.4%) followed by headache (65.3%). In spite of the alarming clinical picture, recovery was rapid and remarkable. Total mortality was 15.5% (8 cases).Conclusions: CVT is more common during the puerperium than in the antenatal period. Obstetric CVT has a more acute onset with excellent recovery when promptly diagnosed and treated.</jats:p
Periyar’s Political Atheism
No full textIntervening in contemporary debates around secularism, this article describes the tension between New Atheism and religious extremism as a “false conflict”. The author argues that political atheism—drawn from his engagement with the works of Periyar E.V. Ramasamy—offers “a radical alternative rooted in a broader critique of hierarchical power”

Efficacy of morphological indexing of ovarian tumor: preoperative determination of risk of malignancy
No full textBackground: Ovarian cancers ranks fifth in cancer death worldwide and in India it ranks third among the female genital tract malignancies. Objective of present study was to assess prospectively the efficacy of morphological indexing (MI) as a method to predict malignancy in sonographically confirmed ovarian tumors.Methods: A prospective study conducted in a tertiary care hospital in Tamil Nadu from September 2011 to August 2012. The risk of malignancy is preoperatively assessed in 136 patients with ovarian tumour using a morphological index based on tumour volume and wall structure. Each tumour was assigned a score of 0 to 10 based on increasing volume and morphologic complexity. The efficacy of the index was assessed by histopathological examination of the tumour.Results: The benign tumours had a mean MI score of 4.3 and malignant tumours had a mean of 8.3 which was statistically significant. Of the 54 tumours with MI <5, only 2 (3.7%) were malignant where else out of the remaining 82 tumours with MI >5, 54 (51.2%) were malignant. With MI >5 as a predictor of malignancy the present study had a Sensitivity-95.5%, Specificity-56.5%, Positive predictive value-51.2%, Negative predictive value-94%, and Accuracy-68%.Conclusions: Morphological index is a simple, valuable and inexpensive diagnostic tool to rule out malignancy in pre operative evaluations of ovarian tumors.</jats:p
