Percentile Data Analysis of Snowfall in J&K and Saichen Glaciers Region

The Indian Himalayas are located between eastings 72° to 96° and the northings 26° to 37°stretching to about 43000 km2 area. There are five major ranges in this region, ie, Pir Panjal,Greater Himalayas, Zanskar, Laddakh, and Karakoram. Saltoro range is the major branch ofwidespread Karakoram ranges which falls in Indian territory. Saichen glaciers are located inSaltoro range. Percentile data of snowfall gives first-hand information about the snowfall patternin Jammu and Kashmir and Saichen glaciers, the two distinguished areas of Indian Himalayaswhich would help in prediction of avalanche activity in these areas. Western disturbanceoriginating from Caspian sea basically dictates the weather condition in this region. Westerndisturbance approaches from western side and hits Pir Panjal range and Greater Himalayan rangefirst, and then either it moves to further north or towards north-eastern region. Westerndisturbance yields maximum precipitation during winter season over north-west Himalayas, butas it moves further, it looses the moisture content, hence reducing the solid snowfall quantitybut stays for a longer duration due to extremely low temperatures observed in the region ofSaichen glaciers. The data analysis shows that the snowfall takes place in Saichen glacierthroughout the year whereas in Jammu and Kashmir area, snowfall takes place only during winterseason. Change in snowfall pattern in these two regions is attributed to the variation intemperature in these regions, movement of weather system, and the difference in altitude. In thepresent study, four locations at varied altitudes from Jammu and Kashmir area and the completeSaichen glaciers region have been covered to analyse the snowfall pattern for the period from1995-2000

Comparison of measured and Monte Carlo-calculated electron depth dose distributions in aluminium

Depth dose profiles in aluminium have been measured using the cellulose triacetate dosimeter against different electron energies (4, 4.5 and 5 MeV) at a recently upgraded 15 kW industrial electron beam accelerator facility. The study also includes comparison of these profiles against Monte Carlo calculations. The measured and simulated depth dose profiles are similar in shape. For all electron energies, at initial depths, the measured doses are higher than the simulated ones. The simulated and measured normalized surface dose values are 0.58 and 0.66, respectively, independent of electron energy. The difference in the surface dose between Monte Carlo and experiment could be attributed to possible presence of low energy electrons in the measurements whereas the Monte Carlo calculations are based on monoenergetic electrons. Between the region of dose maximum and the tail portion of the depth dose curve, the measured dose is smaller than the simulated values (about 17% to 40% at 5 MeV). Using the depth dose profiles, electron beam parameters such as depth at which maximum dose occurs, dmax, practical range, Rp and half-value depth, R50 have been determined. Using the measured parameters Rp and R50, the incident kinetic energy of the electron beam has been determined. The estimated electron energies while using Rp are 4.02, 4.41 and 4.75 MeV. When using R50, the corresponding values are 3.83, 4.21 and 4.64 MeV. The measured RP/R50 ratios are slightly larger than the Monte Carlo-calculated values, which suggest that the electron beam may not be monoenergetic

Prevalence of smokeless tobacco use among school going adolescent students of Raipur city Chhattisgarh state, India

Background: Tobacco consumption in various forms in recent years is a proven risk factor and contributes substantially to the emerging epidemic. Increasing tobacco use and its impact on physical and psychosocial health is a worldwide public health concern affecting the early youth and whole life of the individuals. Tobacco is used in different forms and health effects are seen irrespective of the form in which it is used. Smokeless tobacco is found to be as addictive and harmful as smoking. Objectives: To assess the prevalence and factors influencing smokeless consumption among high school students in Raipur city.Methods: Study design: Cross-sectional, Study area: 16 selected high schools of Raipur city, in which 12 were government schools and 4 private schools. Study subjects: 1006 high-school students, Sampling technique: Two stage cluster sampling according to probability proportional to size, Study tool: Predesigned pretested questionnaire. Statistical analysis: Data was entered in Microsoft excel sheet and analyzed in Epi info 7 software.Results: The mean age of students in the study was 15 years. The prevalence of smokeless tobacco consumption was 10%. Majority male 80.9% were users, mean age of initiation was 13 years (SD 7.07), Peer pressure (76%) was the reason for initiation. Pocket money 57.1% found to be the major source of purchasing. Strong association of family member tobacco use and promotional advertisement were found.Conclusion: Study reflects smokeless tobacco use was prevalent among adolescent students and there is a need for targeted interventions to reduce the risk and deleterious consequences.

Impact of Medical Education Trend in Community Development

Problem-based learning has been described as one of the most significant developments in medical education. The trend of medical education plays a vital role in determining the success of universal health coverage in India.  The motto of health education is community-based training, where students are placed in the community and learn by delivering the care using the existing health services

Role of the cluster structure of 7^7Li in the dynamics of fragment capture

Exclusive measurements of prompt $\gamma$-rays from the heavy-residues with various light charged particles in the $^7$Li + $^{198}$Pt system, at an energy near the Coulomb barrier (E/$V_b$ $\sim$ 1.6) are reported. Recent dynamic classical trajectory calculations, constrained by the measured fusion, $\alpha$ and $t$ capture cross-sections have been used to explain the excitation energy dependence of the residue cross-sections. These calculations distinctly illustrate a two step process, breakup followed by fusion in case of the capture of $t$ and $\alpha$ clusters; whereas for $^{6}$He + $p$ and $^{5}$He + $d$ configurations, massive transfer is inferred to be the dominant mechanism. The present work clearly demonstrates the role played by the cluster structures of $^7$Li in understanding the reaction dynamics at energies around the Coulomb barrier.Comment: 6 pages, 4 figures, Accepted for publication in Phys.

Electromagnetic transition from the 4+^+ to 2+^+ resonance in 8^8Be measured via the radiative capture in 4^4He+4^4He

An earlier measurement on the 4$^+$ to 2$^+$ radiative transition in $^8$Be provided the first electromagnetic signature of its dumbbell-like shape. However, the large uncertainty in the measured cross section does not allow a stringent test of nuclear structure models. The present paper reports a more elaborate and precise measurement for this transition, via the radiative capture in the $^4$He+$^4$He reaction, improving the accuracy by about a factor of three. The {\it ab initio} calculations of the radiative transition strength with improved three-nucleon forces are also presented. The experimental results are compared with the predictions of the alpha cluster model and {\it ab initio} calculations.Comment: 5 pages and 7 figures, Submitted to Physical Review Letter

Lifetime measurements in 63^{63}Co and 65^{65}Co

Lifetimes of the $9/2^-_1$ and $3/2^-_1$ states in $^{63}$Co and the $9/2^-_1$ state in $^{65}$Co were measured using the recoil distance Doppler shift and the differential decay curve methods. The nuclei were populated by multi-nucleon transfer reactions in inverse kinematics. Gamma rays were measured with the EXOGAM Ge array and the recoiling fragments were fully identified using the large-acceptance VAMOS spectrometer. The E2 transition probabilities from the $3/2^-_1$ and $9/2^-_1$ states to the $7/2^-$ ground state could be extracted in $^{63}$Co as well as an upper limit for the $9/2^-_1\rightarrow7/2^-_1$ $B$(E2) value in $^{65}$Co. The experimental results were compared to large-scale shell-model calculations in the $pf$ and $pfg_{9/2}$ model spaces, allowing to draw conclusions on the single-particle or collective nature of the various states.Comment: 8 pages, 8 figures, 1 table, accepted for publication in Physical Review
