Study to Assess the Prevalence of Soft Drinking and its Determinants among the School going Children of Gwalior city
Background: Over the time there has been spectrum of changes in the universe. It may be at physical, chemical and cultural level. People have adopted newer life styles like their working style, clothing’s, food habits and so on. One of the pertinent example of this newer food habits is rising consumption of soft drinks rather than traditional home made drinks. This study was aimed to find out various determinants responsible for this rising trend of soft drinking so that effective intervention can be undertaken to overcome this creeping problem. Objectives: To find out the prevalence of soft drinking consumption among the students and to assess the determinants of soft drink consumption among the students. Materials and methods: It was a cross sectional study. A sample of 200 students was selected from the both govt. and private schools by stratified random sampling. Then they all were interviewed by using pre tested, semi structured proforma. Later on data was analyzed manually and by using suitable statistical software. Results: Frequent drinking of soft drinks was found more among the students of private schools than govt. (p < 0.05). A significant association was found between pocket money, TV watching and frequency of soft drinking (p< 0.05).Other reasons which were found to be responsible by far for frequent soft drinking like lack of awareness regarding hazards, frequent TV watching, desire of new taste, lack of health education from the parents side etc. Conclusion: Soft drinking consumption is creeping day by day amongst the children with out knowing their hazards. And they are the future of any country so there should be effective intervention from both sides govt. as well as parents to get rid of it at earliest
Nutritional Status of Households of Rural Field Practice Area of a Tertiary Care Hospital in India
Introduction: In the world as a whole there appears to be a shift from under-nourishment towards over-nourishment making more and more children, adolescents, adults and even elderly to be overweight and obese. Objectives: Study aimed to find out the age and sex wise commonness of over-weight & obesity amongst the families of an overtly different socio-economic environment and its trend in the members of one type of families. Materials & Methods: The undergraduate medical students are supposed to maintain record of individual health (including height & weight) of their own family as well as that of the allotted family. The data collected (record maintained ) by students was utilized to calculate Body Mass Index (BMI). Results: Out of total 291 subjects (males 168; females 123) in students own family 28.9% (28.0%; 30.1%) were overweight and 5.9% (6.0%; 5.7%) were obese. The similar figures for 262 subjects (males 143 & females 119) in the allotted families were 20.2% (18.5%; 20.2%) and 6.5% (4.2%; 8.4%) respectively. The respective percentages of under nourished individuals were 18.6 (17.9; 19.5) and 35.5 (37.8; 32.8). Thus over-nutrition was more common amongst the members of students own families (34.8% vs. 26.7%) and under-nutrition was more common amongst the members of allotted families (35.5% vs. 18.6%) For the years 2000-2003, BMI amongst individuals of students own families the under-nutrition in the age group of 15-24 years amongst males increased from 15.9% to 32.9% and over-nutrition from 13.6% to 20.5%. There was no case of overweight and obesity up to the age of 34 years in the previous analysis which was 2.6% in the present analysis Previous results demonstrated overweight to be more common in males (32.4% Vs. 24.4% in females) and obesity being more common females ( 6.3% Vs. 2.6% in females). Conclusion: Males are increasingly becoming prey of malnutrition (adolescents for under-nutrition and adults & elderly for over-nutrition. More studies covering larger samples are required to be conducted on a more frequent basis
All Maximally Entangled Four Qubits States
We find an operational interpretation for the 4-tangle as a type of residual
entanglement, somewhat similar to the interpretation of the 3-tangle. Using
this remarkable interpretation, we are able to find the class of maximally
entangled four-qubits states which is characterized by four real parameters.
The states in the class are maximally entangled in the sense that their average
bipartite entanglement with respect to all possible bi-partite cuts is maximal.
We show that while all the states in the class maximize the average tangle,
there are only few states in the class that maximize the average Tsillas or
Renyi -entropy of entanglement. Quite remarkably, we find that up to
local unitaries, there exists two unique states, one maximizing the average
-Tsallis entropy of entanglement for all , while the
other maximizing it for all (including the von-Neumann case of
). Furthermore, among the maximally entangled four qubits states,
there are only 3 maximally entangled states that have the property that for 2,
out of the 3 bipartite cuts consisting of 2-qubits verses 2-qubits, the
entanglement is 2 ebits and for the remaining bipartite cut the entanglement
between the two groups of two qubits is 1ebit. The unique 3 maximally entangled
states are the 3 cluster states that are related by a swap operator. We also
show that the cluster states are the only states (up to local unitaries) that
maximize the average -Renyi entropy of entanglement for all .Comment: 15 pages, 2 figures, Revised Version: many references added, an

Specialty Preference Among Medical Students and Factors Affecting It
Introduction: Medical education is one of the core part of educational system of any country. Medical education requires undergraduate students to study a wide range of medical specialties. It is often assumed that students do not make their career preferences until after they have graduated from medical school. So the reasons and factors responsible for preferences need to be found out among medical students. Material and Methods: It was a Cross sectional study on 180 medical students to assess preference for specialty and factors responsible. Results: Out of total 190 medical students more or less everyone (97.89%) wanted to pursue specialization and majority of them (96.84%) wanted to pursue the same in Medical Field(p>0.05). majority of male students were interested to pursue their specialization in the field of medicine (37.63%), surgery (23.65%) and pediatrics (13.97%). On the other hand female students were more interested in medicine (24.17%), pediatrics (32.96%) and obstetrics & gynecology (24.17%)(p<0.05). Interest, by far was found to be most common factor (76.63%) responsible for the preference of particular medical specialty among all four groups of students (1st professional-25.27%, 2nd professional-75.92%, final professional-89.47%, interns-68.42%).Conclusion: It is thus concluded there are many factors playing role in the specialty selection and preference among the medical students and should be equally justified and addressed
Entanglement of subspaces in terms of entanglement of superpositions
We investigate upper and lower bounds on the entropy of entanglement of a
superposition of bipartite states as a function of the individual states in the
superposition. In particular, we extend the results in [G. Gour,
arxiv.org:0704.1521 (2007)] to superpositions of several states rather than
just two. We then investigate the entanglement in a subspace as a function of
its basis states: we find upper bounds for the largest entanglement in a
subspace and demonstrate that no such lower bound for the smallest entanglement
exists. Finally, we consider entanglement of superpositions using measures of
entanglement other than the entropy of entanglement.Comment: 7 pages, no figure
An Assessment of Knowledge and Practices Regarding Tuberculosis in the Context of RNTCP Among Non Allopathic Practitioners in Gwalior District
Introduction: India has the highest TB burden accounting for one-fifth of the global incidence with an estimated 1.98 million cases. Non- allopathic practitioners are the major service providers especially in rural and peri-urban areas, treating not just patients of diarrhea, respiratory infections and abdominal Pain but also of tuberculosis. Objectives: To assess the knowledge of sign and symptoms of TB and its management as per the RNTCP guidelines and to assess the practicing pattern regarding tuberculosis. Material & Methods: The present was carried out among the registered non allopathic practitioners providing their services in Gwalior District during the study period. A total of 150 non allopathic practitioners of various methods from both government and private sectors were interviewed using a pre-designed, pre-tested semi-structured questionnaire. The information was collected on the General profile of the participant, knowledge about signs and symptoms of TB and its management, practices commonly adopted in the management and their views on involvement of non allopathic practitioners in RNTCP programme. Result: The average score of government practitioners was 7.3 compared to 4.6 by private practitioners. There was a statistically significant difference between the two group on issue related to the management of TB patients as per the RNTCP guidelines. Government practitioners relied mostly on sputum examination for diagnosis and follow up compared to private practitioners who chose other modalities like X-ray, blood examination for this work. Conclusion: There is a gap in knowledge and practices of practitioners of both the sectors. Some serious efforts were required to upgrade the knowledge of non allopathic practitioners if the government is serious about controlling tuberculosis in India
Extensive Entropy Bounds
It is shown that, for systems in which the entropy is an extensive function
of the energy and volume, the Bekenstein and the holographic entropy bounds
predict new results. More explicitly, the Bekenstein entropy bound leads to the
entropy of thermal radiation (the Unruh-Wald bound) and the spherical entropy
bound implies the "causal entropy bound". Surprisingly, the first bound shows a
close relationship between black hole physics and the Stephan-Boltzmann law
(for the energy and entropy flux densities of the radiation emitted by a hot
blackbody). Furthermore, we find that the number of different species of
massless fields is bounded by .Comment: 8 pages, revtex, To appear in Phys. Rev.
Bounds on Bipartitiely Shared Entanglement Reduced from Superposed Tripartite Quantum States
For a tripartite pure state superposed by two individual states, the
bipartitely shared entanglement can always be achieved by local measurements of
the third party. Consider the different aims of the third party, i.e.
maximizing or minimizing the bipartitely shared entanglement, we find bounds on
both the possible bipartitely shared entanglement of the superposition state in
terms of the corresponding entanglement of the two states being superposed. In
particular, by choosing the concurrence as bipartite entanglement measure, we
obtain calculable bounds for tripartite -dimensional
cases.Comment: 8 pages, 2 figures. Accepted by Euro. Phys. J.
Entropy bounds for charged and rotating systems
It was shown in a previous work that, for systems in which the entropy is an
extensive function of the energy and volume, the Bekenstein and the holographic
entropy bounds predict new results. In this paper, we go further and derive
improved upper bounds to the entropy of {\it extensive} charged and rotating
systems. Furthermore, it is shown that for charged and rotating systems
(including non-extensive ones), the total energy that appear in both the
Bekenstein entropy bound (BEB) and the causal entropy bound (CEB) can be
replaced by the {\it internal} energy of the system. In addition, we propose
possible corrections to the BEB and the CEB.Comment: 12 pages, revte
On the Kerr Quantum Area Spectrum
Suppose that there is a quantum operator that describes the horizon area of a
black hole. Then what would be the form of the ensuing quantum spectrum? In
this regard, it has been conjectured that the characteristic frequencies of the
black hole oscillations can be used to calibrate the spacing between the
spectral levels. The current article begins with a brief review of this
conjecture and some of its subsequent developments. We then suggest a simple
but vital modification to a recent treatment on the Kerr (or rotating black
hole) spectrum. As a consequence of this refinement, we are able to rectify a
prior inconsistency (as was found between two distinct calculations) and to
establish, unambiguously, a universal form for the Kerr and Schwarzschild
spectra.Comment: Roughly 8 pages; (v2) added references and very minor change
