Ailing Health Status in West Bengal Critical Analysis
The State of West Bengal in India is at the crossroads in the field of health care delivery system. Nutrition, health and education are the three inputs accepted as significant for the development of human resources and the progress of the State of West Bengal in India during the last decade towards achieving these three inputs has been uneven. The main purpose of this article is to show the health facilities and challenges in West Bengal of India where the problem of providing effective health care services to the majority of its citizens has become an impossible task for the State of Government of West Bengal. Public Health expenditure under the State of West Bengal is so low that there has been hunger and starvation deaths in different districts of West Bengal. Different datas have been cited through different tables bringing into limelight of Infant Mortality Rate, Birth Rate, Death Rate and the facilities of Government of Hospitals of the State of West Bengal.This article has made a focus on the urgency of strengthening the implementation of all the rural and urban health care program and improve infant and child feeding practices among women. It is a challenge for the State of West Bengal in India to meet Millennium Development Goals by 2015. Keywords: Ailing health status in West Bengal , Analysi

Elucidating the Effectiveness of Antibiotic Treatments in Eliminating the Black Dots Contamination from Vero Cell Line Culture
The present study was conducted to identify the effectiveness of various antibiotics and antibiotic combinations in eliminating the black dots contamination in cell culture and to identify its effect on cell growth kinetics. Isolation of contaminant organism (Black dots) observed in our laboratory, was attempted by inoculation of harvested cell supernatant and pellet into Nutrient broth, Luria broth, and Pleuropneumonia-like organisms’ broth but no visible growth was observed. To analyze the effect of antibiotics in elimination of contamination, the cell monolayer was incubated with different antibiotics and combination of antibiotics till 120 hrs. Withdrawal effect of antibiotics was observed by further incubation cells in maintenance media for another 48 hrs. To investigate the effect of different antibiotics on cell growth kinetics, cell seeding was done in media containing antibiotics. A subset of cells was harvested every 24 hrs and counted till 120 hrs. Among all antibiotics, Ampicillin reduced the contamination, the Piperacillin and Tazobactam combination diminished the contamination to a great extent. At the studied concentrations of the antibiotic trio of piperacillin, tazobactam, and ampicillin, black dot contamination was eliminated and found 100% effective in inhibiting contamination within 120 hrs of the study period; but, after 48 hrs of antibiotic withdrawal, contamination reappears in cell culture. The growth kinetics showed no significant impact of antibiotics treatment on the cell growth curve. The growth kinetics showed that cell growth was not interfering significantly by individual or combination of antibiotics. Therefore, in the presence of black dot, a combination of three antibiotics (piperacillin, tazobactam, and ampicillin) should be effective in cell culture
Stability of the monoclinic phase in the ferroelectric perovskite PbZr(1-x)TixO3
Recent structural studies of ferroelectric PbZr(1-x)TixO3 (PZT) with x= 0.48,
have revealed a new monoclinic phase in the vicinity of the morphotropic phase
boundary (MPB), previously regarded as the the boundary separating the
rhombohedral and tetragonal regions of the PZT phase diagram. In the present
paper, the stability region of all three phases has been established from high
resolution synchrotron x-ray powder diffraction measurements on a series of
highly homogeneous samples with 0.42 <=x<= 0.52. At 20K the monoclinic phase is
stable in the range 0.46 <=x<= 0.51, and this range narrows as the temperature
is increased. A first-order phase transition from tetragonal to rhombohedral
symmetry is observed only for x= 0.45. The MPB, therefore, corresponds not to
the tetragonal-rhombohedral phase boundary, but instead to the boundary between
the tetragonal and monoclinic phases for 0.46 <=x<= 0.51. This result provides
important insight into the close relationship between the monoclinic phase and
the striking piezoelectric properties of PZT; in particular, investigations of
poled samples have shown that the monoclinic distortion is the origin of the
unusually high piezoelectric response of PZT.Comment: REVTeX file, 7 figures embedde
Search for a W' boson decaying to a bottom quark and a top quark in pp collisions at sqrt(s) = 7 TeV
Results are presented from a search for a W' boson using a dataset
corresponding to 5.0 inverse femtobarns of integrated luminosity collected
during 2011 by the CMS experiment at the LHC in pp collisions at sqrt(s)=7 TeV.
The W' boson is modeled as a heavy W boson, but different scenarios for the
couplings to fermions are considered, involving both left-handed and
right-handed chiral projections of the fermions, as well as an arbitrary
mixture of the two. The search is performed in the decay channel W' to t b,
leading to a final state signature with a single lepton (e, mu), missing
transverse energy, and jets, at least one of which is tagged as a b-jet. A W'
boson that couples to fermions with the same coupling constant as the W, but to
the right-handed rather than left-handed chiral projections, is excluded for
masses below 1.85 TeV at the 95% confidence level. For the first time using LHC
data, constraints on the W' gauge coupling for a set of left- and right-handed
coupling combinations have been placed. These results represent a significant
improvement over previously published limits.Comment: Submitted to Physics Letters B. Replaced with version publishe
Search for the standard model Higgs boson decaying into two photons in pp collisions at sqrt(s)=7 TeV
A search for a Higgs boson decaying into two photons is described. The
analysis is performed using a dataset recorded by the CMS experiment at the LHC
from pp collisions at a centre-of-mass energy of 7 TeV, which corresponds to an
integrated luminosity of 4.8 inverse femtobarns. Limits are set on the cross
section of the standard model Higgs boson decaying to two photons. The expected
exclusion limit at 95% confidence level is between 1.4 and 2.4 times the
standard model cross section in the mass range between 110 and 150 GeV. The
analysis of the data excludes, at 95% confidence level, the standard model
Higgs boson decaying into two photons in the mass range 128 to 132 GeV. The
largest excess of events above the expected standard model background is
observed for a Higgs boson mass hypothesis of 124 GeV with a local significance
of 3.1 sigma. The global significance of observing an excess with a local
significance greater than 3.1 sigma anywhere in the search range 110-150 GeV is
estimated to be 1.8 sigma. More data are required to ascertain the origin of
this excess.Comment: Submitted to Physics Letters
