Effect of music on post-exercise recovery rate in young healthy individuals

Background: Music has been used in exercise classes for many decades. The role of music in increasing the exercise performance is well recognized but there is very little information about effect of music on post-exercise recovery time.Methods: The present study was conducted to see the effect of musical sounds on post-exercise recovery time following moderate exercise with Harvard step test in young healthy volunteers. 30 young healthy volunteers (17 males, 13 females) aged between 17 to 20 years were recruited for the study. Pulse rate, systolic BP, diastolic BP were recorded prior to exercise in lying down position. The participants were subjected to moderate exercise by Harvard step test for 3 minutes on 3 consecutive days. They were allowed to rest in silence on 1st day, rest with hearing slow music on 2nd day and rest with hearing fast music on 3rd day. During the post-exercise relaxation time PR, SBP and DBP were measured immediately and after every 1 min. until the parameters returned to resting values. Data was statistically analysed using ANOVA test and 0.05 level of significance was set prior to the study.Results: The result showed that with slow music, recovery time of pulse rate (5.2 ± 2.1), systolic blood pressure (3.9 ± 1.1) and diastolic blood pressure (3.2 ± 1.7) were significantly faster as compared to both no music and fast music.Conclusion: The study concluded that music hastens post-exercise recovery and slow music has greater relaxation effect than fast or no music.

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb-Pb collisions at root s(NN)=2.76TeV

The elliptic flow, v(2), of muons from heavy-flavour hadron decays at forward rapidity (2.5 <y <4) is measured in Pb-Pb collisions at root s(NN)= 2.76TeVwith the ALICE detector at the LHC. The scalar product, two- and four-particle Q cumulants and Lee-Yang zeros methods are used. The dependence of the v(2) of muons from heavy-flavour hadron decays on the collision centrality, in the range 0-40%, and on transverse momentum, p(T), is studied in the interval 3 <p(T)<10 GeV/c. A positive v(2) is observed with the scalar product and two-particle Q cumulants in semi-central collisions (10-20% and 20-40% centrality classes) for the p(T) interval from 3 to about 5GeV/c with a significance larger than 3 sigma, based on the combination of statistical and systematic uncertainties. The v(2) magnitude tends to decrease towards more central collisions and with increasing pT. It becomes compatible with zero in the interval 6 <p(T)<10 GeV/c. The results are compared to models describing the interaction of heavy quarks and open heavy-flavour hadrons with the high-density medium formed in high-energy heavy-ion collisions.

Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.

Knowledge and practice regarding contraception and population control among higher secondary school students in Ahmedabad

Background: In India, adolescent pregnancies are very common because of early marriages, lack of knowledge of contraception, and increase in sexual activity among adolescents, together leading to early child bearing in the absence of adequate and effective information and education on planning and spacing children. Objectives: Comparative measurement of knowledge regarding contraception and population control, and to determine the need of inclusion of sex education in curriculum. Materials and Methods: Study was carried out in randomly selected four schools. Two were of central board (private) and two of state board (government) of Ahmedabad, India. A total of 530 apparently healthy students, 265 from each of the two school types aged between 14 and 16 years were recruited for the study. A descriptive study, using a pretested, selfadministered questionnaire, was carried out to assess the knowledge and practice about contraception and population control. Result: Majority of the subjects, 205 (77.35%) of private and 199 (75.04%) of government school, stated that uncontrolled population growth has adverse effects. Only 60% private and 52.83% government school students knew the correct legal age of marriage (p o 0.05). All the respondents were unanimous in their desire for a gap between the first and the second child, but private school students, significantly more (84.90%) than the government school students (71.69%), preferred a gap of more than 2 years between the children (p o 0.05). A significantly higher proportion of central board private school students (90.94%) than state board government school students (72.75%) knew about condoms and contraceptive pills (p o 0.05). Conclusion: Students showed mixed performance regarding knowledge and practice of contraception and population control. There are gaps in knowledge that need to be addressed by including population control and sex education in the school curriculum. Government school students are far behind regarding knowledge of contraception and population control as compared to central board private school students

Original Article - Comparative study of skin staples and polypropylene sutures for securing the mesh in lichtenstein’s tension free inguinal hernia repair: A Prospective randomized controlled clinical trial

BACKGROUND: The tension-free hernioplasty as introduced by Lichtenstein has gained increasing acceptance during the last decade. This study compared two methods of mesh fixation. MATERIAL AND METHODS: Fifty-four patients undergoing sixty repairs were randomized into two groups. In control group polypropylene mesh was secured with 2/0 polypropylene sutures and skin closed with 2/0 polyamide black. In study group polypropylene mesh was secured with skin staples and skin was closed with staples from the same stapler. Duration of the surgery was recorded. RESULTS: The operation was significantly shorter when staples were used (median 42 min 30 s versus 54 min 30 s, P < 0.001). There was no significant difference in the incidence of postoperative complications or pain. There were no recurrences in either group in the follow up period (median 12 months). CONCLUSION: This technique of mesh fixation is as effective as conventional fixation with polypropylene sutures with an important added advantage; significant reduction in the operative time
