Study on the use of tobacco among male medical students in Lucknow, India
Kumari Ranjeeta,Nath Bhola
Indian Journal of Community Medicine , 2008,
Abstract: Objectives: Is use of tobacco a major health problem among medical students? To find out the factors associated with the use of tobacco. Materials and Methods: A cross-sectional study was done on 250 undergraduate male medical students using a pre-designed, pre-tested questionnaire to study about the problem and various correlates of the tobacco use. Data was collected and analysed using Excel and SPSS software. Results: Among the tobacco users (28.8%), smoking was found in 87.5% and tobacco chewing in the form of gutka, khaini, gulmanjan (locally available forms of tobacco) in 37.5% as the predominant means of the use of tobacco. The mean age of our sample was 23.5 years. The residential background, i.e., rural or urban, and religion were not significantly associated with the use of tobacco in the present study. Hostellers were found to be more frequent tobacco users as compared to day-scholars. There was a familial aggregation of the use of tobacco. The factor initiating the use of tobacco was usually peer pressure. Conclusion: Tobacco use is a significant problem among the male medical students and we need to take steps to stop its use by them so as to prevent them from being exposed to its hazardous effects. This will also make their role in the advocacy of the smoking cessation activities more trustworthy.

Sensing Behaviour of Some Nanocomposite Systems  [PDF]
Dipankar Chakravorty, Bhola Nath Pal, Shilpi Banerjee, Amrita Mandal, Sreemanta Mitra, Dhriti Ranjan Saha
Soft Nanoscience Letters (SNL) , 2013, DOI: 10.4236/snl.2013.34A004
Abstract: Silver nanoparticles of diameters 3.4 to 13.2 nm grown at the interfaces between silicate glass and some oxide crystallites exhibited about six orders of magnitude reduction in resistivity for a relative humidity change from 25% to 80%. Sn-SnO2 nano core-shell structure prepared within a gel-derived silica glass film by electrodeposition technique followed by heat treatment showed large change in resistivity as a function of humidity. The resistivity also changed due to gas flow of CO2, C2H5OH and NO2, respectively. The latter arose because of reduction/oxidation of Sn4+/Sn2+ species present at the shell layer of the nanostructures. Nickel nanosheets of thickness ~0.6 nm grown within the interlayer spaces of Na-4 mica crystallites showed a change of dielectric permittivity (5%) for an applied magnetic field of 1.2 Tesla. An inhomogeneous model was used to explain this behavior. Two dimensional CuO phase was grown within the channels of diameter ~5 nm of mesoporous SiO2 structure. A magnetodielectric (MD) parameter M.D. of 4.4% was obtained in this case. BaTiO3 nanoparticles of diameter ~25 nm having pores with diameter 10 nm showed multiferroic behavior which arose due to the presence of oxygen vacancies as a result of large surface area present. An M.D. parameter of 11% was found. Similarly mesoporous LiNbO3 of 10 nm diameter showed an M.D. parameter of ~4.5% at a magnetic field 1 Tesla. A giant magnetocapacitance effect with a value of 44% at 1.5 T was observed in nickel zinc ferrite (NZF) impregnated mesoporous silica. A magnetocapacitance of 51% at magnetic field 1.7 T was found in the case of nanocomposites comprising of iron ion containing silica based nanoglass and mesoporous silica. In the last two examples the behavior was explained on the basis of Catalan model of space-charge polarization with extracted values of magnetoresistance of the NZF and nanoglass phases being 58%.
A study on determinants of immunization coverage among 12-23 months old children in urban slums of Lucknow district, India
Nath Bhola,Singh J,Awasthi Shally,Bhushan Vidya
Indian Journal of Medical Sciences , 2007,
Abstract: Context: To find out the suitable factors for raising the coverage of immunization. Aims : To determine the coverage and to identify the various factors of primary immunization. Settings and Design : Urban slums of Lucknow district. Methods and Material : WHO 30-cluster sampling technique was used for the selection of the subjects. Mother, father or relative of a total of 510 children with 17 children per cluster were interviewed in the study. Statistical Analysis : Chi-square test, binary logistic regression and multinomial logistic regression analysis were done to test the statistical significance of the association. Results: About 44% of the children studied were fully immunized. Multinomial logistic regression analysis revealed that an illiterate mother (OR=4.0), Muslim religion (OR=2.5), scheduled caste or tribes (OR=2.3) and higher birth order (OR≈2) were significant independent predictors of the partial immunized status of the child; while those associated with the unimmunized status of the child were low socioeconomic status (OR=10.8), Muslim religion (OR=4.3), higher birth order (OR=4.3), home delivery (OR=3.6) and belonging to a joint family (OR=2.1). Conclusions: The status of complete immunization is about half of what was proposed to be achieved under the Universal Immunization Program. This emphasizes the imperative need for urgent intervention to address the issues of both dropout and lack of access, which are mainly responsible for partial immunization and nonimmunization respectively.

Bhola Nath,Singh JV,Shally Awasthi,Vidya Bhushan
Online Journal of Health & Allied Sciences , 2008,
Abstract: Background: To determine the knowledge, attitude and practices about immunization among respondents of children aged 12-23 months.Methods: A total of 510 respondents were interviewed in the urban slums of Lucknow district of India, using 30 cluster sampling technique from January 2005 to April 2005. A pre-tested structured questionnaire was used to elicit the information about the knowledge, attitude and practices of the respondents regarding immunization. Results: Knowledge regarding the disease prevented, number of doses and correct age of administration of BCG was highest among all the categories of respondents. The paramedical worker was the main source of information to the respondents of completely (52.0%) and partially immunized (48.5%) children while community leaders for unimmunized children. Those availing private facilities were more completely immunized, as compared to the government facilities. 55.8% of those who took 20 minutes to reach the immunization site were completely immunized as compared to 64.1% of those who took more than 20 minutes.Conclusion: Considering the incomplete knowledge, and inappropriate practices of the people, the policy makers and medical professionals require Herculean efforts to raise the knowledge and to break the old beliefs of the people

Computer Science , 2014,
Abstract: This year (2014) in the month of May, the tenure of the 15th Lok Sabha was to end and the elections to the 543 parliamentary seats were to be held. A whooping $5 billion were spent on these elections, which made us stand second only to the US Presidential elections in terms of money spent. Swelling number of Internet users and Online Social Media (OSM) users could effect 3-4% of urban population votes as per a report of IAMAI (Internet & Mobile Association of India). Our count of tweets related to elections from September 2013 to May 2014, was close to 18.21 million. We analyzed the complete dataset and found that the activity on Twitter peaked during important events. It was evident from our data that the political behavior of the politicians affected their followers count. Yet another aim of our work was to find an efficient way to classify the political orientation of the users on Twitter. We used four different techniques: two were based on the content of the tweets, one on the user based features and another based on community detection algorithm on the retweet and user mention networks. We found that the community detection algorithm worked best. We built a portal to show the analysis of the tweets of the last 24 hours. To the best of our knowledge, this is the first academic pursuit to analyze the elections data and classify the users in the India General Elections 2014.

Discovery of the Sun's million-degree hot corona
H. Peter,Bhola N. Dwivedi
Frontiers in Astronomy and Space Sciences , 2014, DOI: 10.3389/fspas.2014.00002
Abstract: As time goes by, discoveries become common knowledge, and often the person who first changed a paradigm gets forgotten. One such case is the discovery that the Sun's corona is a million degrees hot—much hotter than its surface. While we still work on solving how the Sun heats the corona, the name of the discoverer seems to be forgotten. Instead, other people get the credit who contributed important pieces to the puzzle, but the person who solved this puzzle was someone else. In this historical note we show that this credit should go to Hannes Alfvén (cf. Figure 1).
