ABO incompatibility: its impact on pregnancy and neonate
ABO incompatibility is one of the most common cause of haemolytic disease of fetus and new-born (HDFN). The expression of ABO incompatibility in most of the cases is mild due to the lower expression of A and B Antigens on fetal red cells. ABO incompatibility has affected the first pregnancy and is milder in the subsequent pregnancies. However, we describe this case with unusually severe form of ABO incompatibility which had an effect not only in her first pregnancy but also in all her subsequent pregnancies, evident as recurrent abortions and both her neonates developed pathological jaundice requiring exchange transfusion. It also emphasizes the fact that ABO incompatibility is not always a benign condition and should be considered in all babies whose mothers have O blood group, even in the presence of a negative DAT. Anticipation of ABO incompatibility not only in the first pregnancy but also in the subsequent pregnancies is necessary. Early diagnosis with cord blood bilirubin can prevent neonatal morbidity.
Recognition and Detection of Language on Inscriptions
Ancient language Font Recognition is one of the Challenging tasks in Optical Character Recognition and Document Analysis. Most of the existing methods are for font recognition make use of local typographical features and connected component analysis. In this paper, Ancient language font recognition is done based on global texture analysis. Ancient language characters are different from currentnbsp centuryrsquos Ancient language character. This paper concentrates on the century identification of ancient language characters and converting them into current centuryrsquos form using MATLAB. Recognition of ancient language hand written characters from inscriptions is difficult. In this paper, a method for recognizing Ancient language characters from stone inscriptions, called the contour-let transform, which has been recently introduced, is adopted. From the previous research works, itrsquos noticed that Wavelet transforms are not capable of reconstructing curved images are perfectly. The contour-let transform offers a solution to remedy to this insufficiency. Contour-let transform is a 3D approach technique where as wavelet transform is a 2D technique. The characters from the input image are recognized through the clustering mechanism. Further the noise is present in the image is removed by fuzzy median filters. Neural networks are been employed to train the image and compare the data with the current centuryrsquos character. hence a more accurate recognition of Ancient language characters from stone inscriptions is obtained
IR MPD CDF<SUB>3</SUB> in two-frequency IR fields
The effectiveness of various sets of laser frequencies was analyzed for two-frequency MPD of CDF3 molecule at the different pressures of buffer gas. It was shown that MPD yield increased compared to either single-frequency or two adjacent frequencies irradiation
Far-UV Spectroscopic Analyses of Four Central Stars of Planetary Nebulae
We analyze the Far-UV/UV spectra of four central stars of planetary nebulae
with strong wind features -- NGC 2371, Abell 78, IC 4776 and NGC 1535, and
derive their photospheric and wind parameters by modeling high-resolution FUSE
(Far-Ultraviolet Spectroscopic Explorer) data in the Far-UV and HST-STIS and
IUE data in the UV with spherical non-LTE line-blanketed model atmospheres.
Abell 78 is a hydrogen-deficient transitional [WR]-PG 1159 object, and we find
NGC 2371 to be in the same stage, both migrating from the constant-luminosity
phase to the white dwarf cooling sequence with Teff ~= 120 kK, Mdot ~= 5x10^-8
Msun/yr. NGC 1535 is a ``hydrogen-rich'' O(H) CSPN, and the exact nature of IC
4776 is ambiguous, although it appears to be helium burning. Both objects lie
on the constant-luminosity branch of post-AGB evolution and have Teff ~= 65 kK,
Mdot ~= 1x10^-8 Msun/yr. Thus, both the H-rich and H-deficient channels of PN
evolution are represented in our sample. We also investigate the effects of
including higher ionization stages of iron (up to FeX) in the model atmosphere
calculations of these hot objects (usually neglected in previous analyses), and
find iron to be a useful diagnostic of the stellar parameters in some cases.
The Far-UV spectra of all four objects show evidence of hot (T ~ 300 K)
molecular hydrogen in their circumstellar environments.Comment: 38 pages, 8 figures (6 color). Accepted for publication in Ap
Dynamics of Rural Labor Markets in India: Implications for Inclusive Development Strategy
The rural labor market in India has undergone remarkable changes over the years. Diversified opportunities for employment with increased economic growth, introduction of employment guarantee scheme, demographic change along with expansion of universal education for all girls and boys, increased connectivity and mobility from rural to urban areas, changes in trade policies, attitude towards participation of women in economic activities outside their home have altered the rural labor market dynamics. This policy brief deals with the dynamics of rural labor markets in India. It focuses on the trends in rural employment, rural labor markets, and sources of livelihood and living standards of the rural labor class. It documents both short and long-term changes in rural labor markets observed in India. It identifies the key drivers of changes in the rural labor market, determinants of labor supply and wage rate. Finally, some suggestions are put forward to overcome the challenges in the rural labor market and for an inclusive growth strategy in India. The term inclusive growth is used in this policy brief to include landless labor, smallholder farmers, women and youth who will all be an integral part of the growth process and benefit from the rural and overall economic growth in the country..
HST/WFPC2 snapshot imaging of symbiotic stars
The results of a HST/WFPC2 snapshot imaging survey of selected symbiotic
stars in 1999/2000 are presented. Seven sources - HD 149427 (PC 11), PU Vul, RT
Ser, He2-104 (Southern Crab), V1329 Cyg (HBV 475), V417 Cen, AS 201 - were
observed in filters F218W (ultraviolet continuum), F502N ([OIII]lambda
4959,5007) and F656N (Halpha); an eighth source, RS Oph, was observed in F437N
([OIII]lambda 4363), F502N and F656N. The presence of extended emission was
detected in He2-104, V1329 Cyg and possibly HD 149427. In He2-104 we detected
the [OIII] and Halpha counterparts to the inner lobes found in [NII] by Corradi
et al. For V1329 Cyg, comparison with previously published HST/FOC results
indicates expanding ejecta which may be associated with an ejection event in
1982 (+/-2 years) at a velocity of 260 +/- 50 km/s in the plane of the sky and
at an assumed distance of 3.4kpc. We also present previously unpublished radio
images of HD 149427, which we have obtained from the archives of the Australia
Telescope Compact Array and which reveal the presence of extended emission at a
similar orientation to that of the possible optical extension. Finally we also
include HST/WFPC2 GO observations of AG Peg and detect possible extended
emission in the F218W filter.Comment: 8 pages, accepted for publication in MNRA
Transport properties of copper phthalocyanine based organic electronic devices
Ambipolar charge carrier transport in Copper phthalocyanine (CuPc) is studied
experimentally in field-effect transistors and metal-insulator-semiconductor
diodes at various temperatures. The electronic structure and the transport
properties of CuPc attached to leads are calculated using density functional
theory and scattering theory at the non-equilibrium Green's function level. We
discuss, in particular, the electronic structure of CuPc molecules attached to
gold chains in different geometries to mimic the different experimental setups.
The combined experimental and theoretical analysis explains the dependence of
the mobilityand the transmission coefficient on the charge carrier type
(electrons or holes) and on the contact geometry. We demonstrate the
correspondence between our experimental results on thick films and our
theoretical studies of single molecule contacts. Preliminary results for
fluorinated CuPc are discussed.Comment: 18 pages, 16 figures; to be published in Eur. Phys. J. Special Topic
Heisenberg Picture Approach to the Stability of Quantum Markov Systems
Quantum Markovian systems, modeled as unitary dilations in the quantum
stochastic calculus of Hudson and Parthasarathy, have become standard in
current quantum technological applications. This paper investigates the
stability theory of such systems. Lyapunov-type conditions in the Heisenberg
picture are derived in order to stabilize the evolution of system operators as
well as the underlying dynamics of the quantum states. In particular, using the
quantum Markov semigroup associated with this quantum stochastic differential
equation, we derive sufficient conditions for the existence and stability of a
unique and faithful invariant quantum state. Furthermore, this paper proves the
quantum invariance principle, which extends the LaSalle invariance principle to
quantum systems in the Heisenberg picture. These results are formulated in
terms of algebraic constraints suitable for engineering quantum systems that
are used in coherent feedback networks
