Streaming Big Data Analysis for Real-Time Sentiment based Targeted Advertising

Big Data constituting from the information shared in the various social network sites have great relevance for research to be applied in diverse fields like marketing, politics, health or disaster management. Social network sites like Facebook and Twitter are now extensively used for conducting business, marketing products and services and collecting opinions and feedbacks regarding the same. Since data gathered from these sites regarding a product/brand are up-to-date and are mostly supplied voluntarily, it tends to be more realistic, massive and reflects the general public opinion. Its analysis on real time can lead to accurate insights and responding to the results sooner is undoubtedly advantageous than responding later.  In this paper, a cloud based system for real time targeted advertising based on tweet sentiment analysis is designed and implemented using the big data processing engine Apache Spark, utilizing its streaming library. Application is meant to promote cross selling and provide better customer support

A Rapid Protocol for Somatic Embryogenesis Mediated Regeneration in Banana (Musa Spp.) Cv. Nendran

A simple and rapid protocol for somatic embryogenesis in banana cv. Nendran (AAB) using immature male flowers (IMF) has been developed. The IMF produced palewhite to yellow, globular embryogenic callus on MS medium supplemented with BA (0.05 - 0.50mgL-1) and picloram (0.50 - 2.00mgL-1) with explant response of to 30 per cent. Addition of ascorbic acid (20mgL-1) and Gelrite© (0.45 per cent) to callus induction medium reduced interference from phenolic exudation. Embryogenesis was induced (33.3 to 60 per cent) on semisolid (0.30 per cent Gelrite©) MS medium supplemented with BA 2mgL-1 + IAA 0.5mgL-1. The somatic embryos showed 60-80 per cent germination on half- strength semisolid MS medium with BA 2mgL-1 + IAA 0.5mgL-1. Transfer of germinated embryos to semisolid MS medium supplemented with BA 2mgL-1 + NAA 1mgL-1under 14 h light /8h dark photoperiod resulted in hundred percent conversion to plantlets. This protocol takes merely 6 months for producing plantlets from immature flower buds through somatic embryogenesis, without any intermediate liquid cultures

Radiological Pitfalls in Patients with Inducible Dynamic Proptosis

We report two patients presenting with marked clinical unilateral enophthalmos who had positional variability and dynamic proptosis on valsalva. On orbital imaging, enophthalmos was not documented and in fact, globe proptosis of the same side was reported for one of the patients. During CT and MRI scanning patients are often instructed to hold their breath to eliminate motion artefact. This may inadvertently induce dynamic proptosis. The radiological pitfalls of imaging patients with inducible dynamic proptosis and how to identify such patients are discussed

Clinical and biochemical profile of scrub typhus patients with emphasis on liver dysfunction in a tertiary care centre in South Rajasthan

Background: Scrub typhus is a zoonotic infectious disease presenting commonly with acute febrile illness of variable severity and symptoms. It mimics other more prevalent tropical febrile illnesses such as dengue, malaria, and leptospirosis. Prevalence is high in and around Udaipur due to hilly terrains and agricultural farmlands. Multisystem involvement is common but liver dysfunction is a fatal comorbidity. Methods: In a retrospective observational study, we analyzed the clinical, biochemical, and demographic parameters of 85 patients of scrub typhus. The study population was distributed into four groups for abnormal liver chemistries based on American College of Gastroenterology (ACG) clinical guidelines: normal, borderline high, mild elevation, and moderate elevation. Results: Almost 80% of patients had abnormal liver chemistries including either serum bilirubin or transaminases. More than 30% of patients were categorized in group 2 and group 3 of the abnormal liver chemistries. Group 4 with moderate to severe liver dysfunction had 15.3% (n=13) patients. Thrombocytopenia and elevated blood urea and Creatinine were significantly seen in patients with both scrub typhus and liver dysfunction. Conclusions: Thus, in our study prevalence of hepatitis and jaundice with multiorgan failure in scrub typhus patients was significantly high. Timely identification of systemic complications and screening of liver chemistries on presentation is of utmost importance for better outcomes, among seriously ill patients

A pharmacovigilance study of anti-depressant agents in psychiatric patients at a tertiary care teaching hospital

Background: Anti-depressant drugs have great benefit in treating a many psychiatric disorders, including schizophrenia and bipolar disorder, although all these drugs are associated with many potential adverse effects. In this study, the occurrence of adverse effects like weight gain, sleep disturbances, dry mouth were assessed and reported in drug naïve patients Anti-depressant drugs.Methods: It is a prospective observational study of patients attending Psychiatry department in NRI General Hospital of age 10 to 80 years who were prescribed with anti-depressant drugs. The study was conducted for a period of 8 months from June 2018 to February 2018.Results: Among 86 patients prescribed with antidepressants, the occurrence of adverse drug reactions due to antidepressants was 60.78% with Selective serotonin reuptake inhibitors being the most common class of drugs implicated for adverse drug reactions followed by 24.49% with Tricyclic antidepressants. A total of 51 adverse drug reactions were noted of which weight gain was most common, closely followed by sleep disturbances and drowsiness. Out of 52 adverse drug reactions assessed for causality, 88.2% of the adverse drug reactions cases were probable, while 11.7% were possible. According to Hartwig and Siegel’s Scale 84.3% of the cases are found to be mild, 15.68% moderate.Conclusions: The study allows knowing information about the occurrence and pattern of adverse drug reactions associated with Anti-depressant drugs in the population thus reducing its incidence and protecting the user population from available harm

Air-Sea Interaction in the Bay of Bengal

Recent observations of surface meteorology and exchanges of heat, freshwater, and momentum between the ocean and the atmosphere in the Bay of Bengal are presented. These observations characterize air-sea interaction at 18°N, 89.5°E from December 2014 to January 2016 and also at other locations in the northern Bay of Bengal. Monsoonal variability dominated the records, with winds to the northeast in summer and to the southwest in winter. This variability included a strong annual cycle in the atmospheric forcing of the ocean in the Bay of Bengal, with the winter monsoon marked by sustained ocean heat loss resulting in ocean cooling, and the summer monsoon marked by strong storm events with dark skies and rain that also resulted in ocean cooling. The spring intermonsoon was a period of clear skies and low winds, when strong solar heating and weak wind-driven mixing led to ocean warming. The fall intermonsoon was a transitional period, with some storm events but also with enough clear skies and sunlight that ocean surface temperature rose again. Mooring and shipboard observations are used to examine the ability of model-based surface fluxes to represent air-sea interaction in the Bay of Bengal; the model-based fluxes have significant errors. The surface forcing observed at 18°N is also used together with a one-dimensional ocean model to illustrate the potential for local air-sea interaction to drive upper-ocean variability in the Bay of Bengal

Nanoindentation and structural studies of MgO-doped congruent LiNbO3 single crystals

The mechanical properties of undoped and 2.0, 4.0 and 6.0 mol% Mg-doped LN single crystals, grown by the Czochralski technique, have been investigated using nanoindentation studies to understand the mechanical deformation behaviour as doping is increased. This has been correlated with structural investigations by powder XRD analysis and Raman spectroscopy. Powder X-ray diffraction measurements show a slight increase in the lattice parameters as the Mg content is increased in the crystal. The lattice strain developed due to the doping has been calculated by the Williamson-Hall relation. The influence of Mg incorporation on lattice vibrations was analysed using Raman spectroscopy, which indicated no shift in the peak positions with doping, and only slight variation in the intensity and width of the peaks. The grown crystals were subjected to nanoindentation and the Young's modulus and hardness values were obtained by using the Oliver-Pharr method. The results reveal the optimal doping levels of Mg which result in enhanced mechanical strength of lithium niobate single crystals.publishe
