Measurement of Orbital Decay in the Double Neutron Star Binary PSR B2127+11C

We report the direct measurement of orbital period decay in the double neutron star pulsar system PSR B2127+11C in the globular cluster M15 at the rate of $(-3.95 \pm 0.13) \times 10^{-12}$, consistent with the prediction of general relativity at the $\sim 3$ level. We find the pulsar mass to be $m_p = (1.358 \pm 0.010) M_\odot$ and the companion mass $m_c = (1.354 \pm 0.010) M_\odot$. We also report long-term pulse timing results for the pulsars PSR B2127+11A and PSR B2127+11B, including confirmation of the cluster proper motion.Comment: 12 pages, 4 figures, accepted for publication in ApJ

Scenario Analysis of Impacts of Changes in Technology, Fertilizer Prices, Highways, Labor Markets, Consumption Expenditure, Rainfall and Price Policy for Semi-Arid Tropical Crop Markets

A major purpose of ICRISAT is to develop new technologies and procedures which will increase the productivity of the five mandate SAT crops (sorghum, pearl millet, pigeonpeas, chickpeas and groundnuts) under a variety of environmental conditions. But a productivity change for a particular crop may have important impacts not only on production of that crop, but also on its market price and on the income and therefore the expenditure of its producers..

Market Impacts of Technological Change for Sorghum in Indian Near-Subsistence Agriculture

Evaluating market impacts of technological change for near-subsistence crops like sorghum in semiarid tropical India is complicated because of diversified agriculture, geographically isolated markets, and therefore feedbacks through prices, and producer-demander income links for such products. Dynamic simulations with a multicommodity market model suggest that increased sorghum productivity would have spillover effects on other markets, increase the welfare of sorghum consumers, and probably lower the sorghum price. Contrary to speculations of some experts, the output gain probably would be greater than the pure productivity effect despite the price decline because of induced input allocations favoring sorghum production

Holographic grating based Ebert spectrograph

In this paper we discuss the aberration properties and design procedure of in-plane Ebert spectrograph using conventional as well as holographic diffraction gratings. In both cases the gratings are situated at the well-known √3-position so that the spectrum can be recorded on a flat surface. It has been found that the holographic grating system has better resolution than the conventional grating system. The design parameters of a medium sized holographic grating spectrograph in which a concave spherical mirror is mounted in the off-axis configuration have been specified. The performance of the spectrograph has been evaluated by plotting spot diagram

Flat field spectrograph using convex holographic diffraction grating and concave mirror

In this paper we have discussed the aberration properties and the design procedure of a spectrograph which uses a convex holographic grating as the dispersing element and a concave mirror as the focusing element. Both the concave mirror and the convex grating have common axis and they are concentric. The grating is constructed by recording the interference fringes on the convex surface which are formed by two convergent light beams incident from opposite sides of the axis. The illuminating source of the spectrograph is located on a plane perpendicular to the axis and passing through the common centre. It has been found that under certain conditions both positive and negative order spectra are perfectly focused on this plane. Aberration properties of the zero order image as well as the positive and the negative order spectral images have been studied by actual ray tracing. Using this system, design parameters of a medium-sized spectrograph having moderate dispersion and good resolution throughout theuv-visible region of the spectrum have been specified. The performance of the spectrograph has been evaluated by plotting spot diagram
