Deformed Twistors and Higher Spin Conformal (Super-)Algebras in Six Dimensions

Massless conformal scalar field in six dimensions corresponds to the minimal unitary representation (minrep) of the conformal group SO(6,2). This minrep admits a family of deformations labelled by the spin t of an SU(2)_T group, which is the 6d analog of helicity in four dimensions. These deformations of the minrep of SO(6,2) describe massless conformal fields that are symmetric tensors in the spinorial representation of the 6d Lorentz group. The minrep and its deformations were obtained by quantization of the nonlinear realization of SO(6,2) as a quasiconformal group in arXiv:1005.3580. We give a novel reformulation of the generators of SO(6,2) for these representations as bilinears of deformed twistorial oscillators which transform nonlinearly under the Lorentz group SO(5,1) and apply them to define higher spin algebras and superalgebras in AdS_7. The higher spin (HS) algebra of Fradkin-Vasiliev type in AdS_7 is simply the enveloping algebra of SO(6,2) quotiented by a two-sided ideal (Joseph ideal) which annihilates the minrep. We show that the Joseph ideal vanishes identically for the quasiconformal realization of the minrep and its enveloping algebra leads directly to the HS algebra in AdS_7. Furthermore, the enveloping algebras of the deformations of the minrep define a discrete infinite family of HS algebras in AdS_7 for which certain 6d Lorentz covariant deformations of the Joseph ideal vanish identically. These results extend to superconformal algebras OSp(8*|2N) and we find a discrete infinite family of HS superalgebras as enveloping algebras of the minimal unitary supermultiplet and its deformations. Our results suggest the existence of a discrete family of (supersymmetric) HS theories in AdS_7 which are dual to free (super)conformal field theories (CFTs) or to interacting but integrable (supersymmetric) CFTs in 6d.Comment: 30 pages; Latex file; Discussion in section 3.2 expanded; typos corrected; minor modifications; version to be published in JHE

Urban Development Strategy for Bihar: A Management Perspective

Bihar is among the least urbanized states in India with a level of urbanization just above 10% in 2001. The present study suggests a four-stage strategy for the urban development of Bihar. The stages are- (i) Increase in the rate of urbanization (ii) Increase in the resources of Urban Local Bodies (ULBs) (iii) Improvement in delivery of urban services, and (iv)Local economic development for employment generation in cities. The current state of finances of ULBs in Bihar is very poor on account of low yield of own revenue sources and low level of grants. The quality of services provided by ULBs in Bihar, measured by expenditure on these services is inferior in comparison to standard benchmarks and other selected cities in India. The location quotient analysis of cities in Bihar reveals lack of industrial development, and reliance on primary activities for employment. Positive correlation between economic growth and share of service sector in employment and negative correlation between economic growth and primary sector employment justify the need for efforts towards development of industrial and service sectors in the state.

Management of Blood Transfusion Services in India: An Illustrative Study of Maharashtra and Gujarat States

Blood is a vital healthcare resource routinely used in a broad range of hospital procedures. It is also a potential vector for harmful, and sometimes fatal, infectious diseases such as HIV, HBV, and HCV. Morbidity and mortality resulting from the transfusion of infected blood have far-reaching consequences. The economic cost of a failure to control the transmission of infection is visible in countries with a high prevalence of HIV. Shortfalls in blood supply have a particular impact on women with pregnancy complications, trauma victims and children with severe life-threatening anaemia. Ensuring a safe, source and ethical supply of blood and blood products and rational clinical use of blood are important public health responsibilities of every national government. Blood transfusion services in India rely on very fragmented mix of competing independent and hospital based blood banks of different levels of sophistication, serving different types of hospitals and patients. Voluntary and non-remunerated blood is in short supply. The SACS ensure only the availability of safe blood in blood banks. Clinical use of blood is not monitored, and the use of blood components is very low. Managing blood transfusion services involves donor management, blood collection, testing, processing, storing, issue of safe blood and blood products when clinically needed, and staff training. Maharashtra Government, by setting up its State Blood Transfusion Council as an independent unit under the Department of Health, has set up an excellent example to address the above managerial issues in meeting the transfusion requirements than any fragmented system. We strongly recommend the Maharashtra model to all other states and union territories in India.

Petrology and physical conditions of metamorphism of calcsilicate rocks from low- to high-grade transition area, Dharmapuri District, Tamil Nadu

Calc-silicate rocks comprising quartz, plagioclase, diopside, sphene, scapolite, grossularite-andradite and wollastonite occur as lensoid enclaves within the greasy migmatitic and charnockitic gneisses of the Archaean amphibolite- to granulite-facies transition zone in Dharmapuri district, Tamil Nadu. The calc-silicate rocks are characterized by the absence of K-feldspar and primary calcite, presence of large modal quartz and plagioclase and formation of secondary garnet and zoisite rims around scapolite and wollastonite. The mineral distributions suggest compositional layering. The chemical composition and mineralogy of the calc-silicate rocks indicate that they were derived from impure silica-rich calcareous sediments whose composition is similar to that of pelite-limestone mixtures. From the mineral assemblages the temperature, pressure and fluid composition during metamorphism were estimated. The observed mineral reaction sequences require a range of X sub CO2 values demonstrating that an initially CO2-rich metamorphic fluid evolved with time towards considerably more H2O-rich compositions. These variations in fluid composition suggest that there were sources of water-rich fluids external to the calc-silicate rocks and that mixing of these fluids with those of calc-silicate rocks was important in controlling fluid composition in calc-silicate rocks and some adjacent rock types as well

X-Ray Fluoresence Spectrometry in Geological Samples

Geological samples comprising of various rocks, ores and minerals need to be studied for their elemental chemical data. X-ray fluorescence spectrometry is a precise and accurate analytical technique for determining elements from atomic No.4 (boron) to 92 (uranium) at concentration levels of 100% to a few parts per million (ppm) in solids, liquids and powders. The non-destructive nature of anal- ysis, speed, versatility, automation, sensitivity, sele-ctivity, large sample throughput have made XRF technique a widely practised and well established technique for the determination of major, minor and trace elements in rock samples

Fiscal Decentralization: Does The Source Of Revenue Matter?

Fiscal Decentralization: does the Source of Revenue Matter? Evidence from Rural India Pallavi Jain Govil Adviser: Professor Timothy J. Goodspeed Is the pattern of expenditures of village governments related to their sources of revenue? Do village governments use own-source revenues more efficiently than transfer grants to provide public services to their constituents? This paper begins with the premise that local governments are more participative, more acceptable, and more accountable and hence, deliver better. I use a policy change introduced in 1997 in province of Madhya Pradesh in India, whereby the power to collect royalty and lease rents on minor mineral mines and fishing tanks was transferred to village governments, as a natural experiment and examine whether expenditure patterns of villages that received such resources differ from those that did not. I find that village governments choose to spend their fiscal resources differently depending on where the money comes from, even if these resources are completely `untied\u27 and could be spent entirely at the discretion of the village governments. I also compare the social outcomes in villages that gained such additional resources to those that didn\u27t, and thus remained more dependent on transfer grants from the state and central government for their development needs. Using village level data, I find evidence to support the hypothesis that fiscal decentralization through assignment of taxation powers is more effective in achieving desired outcomes as compared to a transfer of an equal amount of resources by way of grants

Assessment of On-going tectonic deformation in the Goriganga River Basin, Eastern Kumaon Himalaya Using Geospatial Technology

The Goriganga river basin lies in the Northeast Kumaon Himalaya and is found suitable for assessing active tectonics at different scales. In addition, this study focuses on the assessment of ongoing tectonic activity through morphotectonic measurement of the Goriganga river basin, which is an ideal location for such analysis and Goriganga river basin transects with three major domains of Himalaya’s lithotectonic structures viz., Tethys, Vaikrita, and Lesser Himalayan Domain. To realize this task, the ASTER Digital Elevation Model was used and found suitable to extract different morphotectonic indices such as Stream Length Gradient (SL), Hypsometric Integral (HI), Length of Overland Flow (Lg), Drainage Density (Dd) and Channel Sinuosity (Cs).  Results of these important indices, including SL (18- 4737) HI (0.26- 0.57), and Lg (0.08- 0.19) depict greater variability in the tectonics activity while these values are correspondingly high in the close proximity of lithotectonic units, showing strong tectonic activity. In the extreme south, the Rauntis Gad basin strongly influences tectonism due to transecting syncline and anticline as well as unknown active faults.
