The yields of various fission products in the neutron-induced fission of 238U with the flux-weightedaveragedneutron energies of 9.35 MeV and 12.52 MeV were determined by using an off-line gammarayspectroscopic technique. The neutrons were generated using the 7Li(p, n) reaction at BhabhaAtomic Research Centre-Tata Institute of Fundamental Research Pelletron facility, Mumbai. Thegamma- ray activities of the fission products were counted in a highly-shielded HPGe detector overa period of several weeks to identify the decaying fission products. At both the neutron energies, thefission-yield values are reported for twelve fission product. The results obtained from the presentwork have been compared with the similar data for mono-energetic neutrons of comparable energyfrom the literature and are found to be in good agreement. The peak-to-valley (P/V) ratios werecalculated from the fission-yield data and were found to decreases for neutron energy from 9.35 to12.52 MeV, which indicates the role of excitation energy. The effect of the nuclear structure on thefission product-yield is discussed.
Correlation Between Pain, Fear of Falling and Disability in Low Back Pain
Sadhana Verma,Bharat Prakash Pal 대한재활의학회 2015 Annals of Rehabilitation Medicine Vol.39 No.5
Objective To ascertain if there is a correlation between low back pain (LBP), fear of falling, and disability so that the patients with LBP are aware of the fact that other problems may occur with LBP. Hence, steps can be taken for decreasing the fear of falling and disability in order to improve the condition of patients.Methods A sample size of 100 patients with low back pain, with a range of ages from 40 to 73 years, participated in the study. The Falls Efficacy Scale was used to assess the fear of falling and the Oswestry Disability Index was used to assess the disability and pain in LBP individuals.Results The Pearson correlation analysis signifies the relationship between pain, fear of falling, and disability in LBP.Conclusion First, LBP increases the fear of falling. Second, LBP can result in a person becoming disabled. Third, the fear of falling and disability are correlated with each other.

Purpose: Active involvement of students in their learning process is a recommended andragogical approach to increase student engagement. Many new teaching-learning strategies based on active learning have been implemented, but their efficacies to achieve the proposed benefits of attaining knowledge, skills, and attitude have not been evaluated, especially in the field of medical education. We substituted passive learning in the conventional tutorial classes with an active-learning strategy of Student-Led Seminar Series (SLSS) in the subject of physiology over 4 months and performed program evaluation for the SLSS. Methods: Sixty-four first-year medical undergraduate students volunteered to participate, who were divided into groups to present seminars on the allocated topics under the guidance of a mentor. At the end of 4 months, program evaluation was done using Kirkpatrick’s model of evaluation—levels 1 and 2, which correspond to reaction and learning, respectively. Results: Statistically significant improvement was observed in students’ satisfaction, and the self-perceived increase was observed in knowledge, skills, and attitude. Conclusion: Program evaluation of SLSS not only established the significant impact of SLSS as an andragogical approach but also helped us in the improvisation of the program for the next cycle.
Sneak Peek into Tobacco Habits and Associated Insidious Oral Lesions in an Odisha Sample Population

Background: Tobacco use in various forms, including with Areca nut, causes several potentially malignant disorders. Many lesions may transform into oral squamous cell carcinoma. Although patients may be aware of the hazards of tobacco habits, the lesions by themselves are insidious in nature resulting in failure of patients to present to general dentists/specialists at early stages. Our aim was to study the types of habits prevalent in the region of Rourkela in Orissa and to assess the insidious nature of the lesions associated with these habits. Not many studies have been done from this part of India. Materials and Methods: A camp was conducted for habitual users of tobacco and its products, Areca nut and other mixed habit users. A thorough history was taken of the type, duration and frequency of habits, symptoms of patients along with clinical examination by a single examiner. The data was entered in detail into an excel sheet and analysed. Results: 54.7% had lesions and 60.9 % of them were asymptomatic and rest had mild burning sensation while eating. There was a very low awareness of the presence of lesions among the patients. Conclusions: There is a need to spread the awareness of the ill effects of the tobacco and other associated habits far and wide and more importantly educate the general public on the appearance of associated lesions as these are almost always insidious in nature. The patients can self-examine, detect lesions early when present and approach the dentist at the earliest opportunity.

<P>The charged-particle multiplicity distribution and the transverse-energy distribution measured in heavy-ion collisions at top RHIC and LHC energies are described using the two-component model approach based on a convolution of the Monte Carlo Glauber model with the Weibull model for particle production. The model successfully describes the multiplicity and transverse-energy distribution of minimum-bias collision data for a wide range of energies. The Weibull-Glauber model can be used to determine the centrality classes in heavy-ion collisions as an alternative to the conventional negative binomial distribution (NBD)-Glauber approach.</P>

Background: Cancer of the uterine cervix is one of the most common cancers among women worldwide. Industrialized countries have dramatically reduced the incidence of mortality from cervical carcinoma in the last 50 years through aggressive screening programs utilizing pelvic examinations and Papanicolaou (Pap) smears but it still remains a major problem in the developing world. Objectives: This study was performed to determine knowledge, attitude and practice of Pap smear as a screening procedure among nurses in a tertiary hospital in north eastern India. Material and Methods: This cross sectional study was carried out with a questionnaire survey covering the socio demographic factors, knowledge, attitude and practices about Pap smear screening among 224 nurses in Regional Institute of Medical Sciences, Imphal, Manipur, India during December 2011. Results: Two hundred and twenty one participants (98.6%) had heard about cervical carcinoma but 18.3% lacked adequate knowledge regarding risk factors. Knowledge about the Pap smear was adequate in 88.8% of the respondents. Out of these, only 11.6% had Pap smear at least once previously. The most common reasons for non-participation in screening were lack of any symptoms (58.4%), lack of counselling (42.8%), physician does not request (29.9%) and fear of vaginal examination (20.5%). Conclusion: Although knowledge of Pap smear as a screening procedure for cervical cancer is high, practice is still low. The nurses who should be responsible for opportunistic screening of women they care for are not keen on getting screened themselves. If we can improve the practice of Pap smear screening in such experts, they should be able to readily provide appropriate and accurate information and motivate the general population to join screening programs.

Previous work reveals a syn-tectonic granite named Phulad granite, which is emplaced (~820 Ma) in the western part of the South Delhi Fold Belt (SDFB) along and across the Phulad Shear Zone (PSZ). There is a lack of information about the detailed microstructural study, differential stress and strain rate variation from this granite body. These pieces of information are crucial in developing deformational history associated with the shear zone deformation. The granite preserves a variety of dynamic recrystallization from grain boundary bulging (BLG) to sub-grain rotation (SGR) to grain boundary migration (GBM). There is a variation in the fractal dimension (D) in the granite, such as higher D at the shear zone, and with increasing distance from the shear zone, D values are low. Strain rates (10−7.52 s−1–10−7.99 s−1) are much higher than the geological strain rates in the natural systems. The strain rates indicate that the method to calculate strain rate using the D value (1.007 ± 0.017 to 1.031 ± 0.022) is to some extent erroneous or fails to give geologically reasonable value for high-temperature syn-tectonic granite such as Phulad granite. Based on the quartz piezometer, our findings reveal variation in flow stress with distance from the shear zone, which depends on the grain size. Volume gain and mass balance calculations indicate that fluid incorporation at the shear zone reduces deformation temperature, which also validates the findings from the microstructural study. These microstructures and grain size calculations are discussed to interpret the deformation mechanism, various stress-strain pattern and evolution of the Phulad granite throughout the area.

The current study stresses on the reuse of waste lignocellulose biomass (rice husk and sugarcane bagasse) for the synthesis of carboxymethyl cellulose (CMC) and further conversion of this CMC into a biodegradable film. Addition of commercial starch was done to form biodegradable film due to its capacity to form a continuous matrix. Plasticizers such as Glycerol and citric acid were used to provide flexibility and strength to the film. Biopolymer film obtained from sugarcane bagasse CMC showed maximum tensile strength and elongation in comparison to the film synthesized from commercial CMC and CMC obtained from rice husk. It has been observed that an increase in sodium glycolate/NaCl content in CMC imposed an adverse effect on tensile strength. Opacity, moisture content, and solubility of the film increased with a rise in the degree of substitution of CMC. Therefore, CMC obtained from sugarcane bagasse was better candidate in preparing biopolymer/biocomposite film.
