Evolution of Crop-dairy Production Systems in South India from 1971 to 2002

It is widely believed that not only a Green Revolution in a crop sector but also a White Revolution in a dairy sector has generated the great momentum of agricultural development in India since the late 1960s. However, due to the dominance of sector-specific analyses, the importance of the interaction between these two sectors has been neglected in the existing literature. The interaction is important in that the dairy sector provides manure to crop production while the crop sector supplies fodder to the dairy. Using household data collected in Tamil Nadu, India for three decades from 1971, we show the increase of fodder production as a byproduct of Green Revolution in 1970s enabled subsequent White Revolution in 1980s and the byproduct of the White Revolution, i.e. increased manure availability, is enhancing the recent revival of organic farming system for sustainable agricultural development.Green revolution, White revolution, agricultural system, India, Production Economics, M3, O13, Q12, Q13, Q56,

Phase transition in the 3 Kelvin phase in the eutectic Sr2RuO4-Ru

The inhomogeneous 3-Kelvin (3K) phase of the eutectic Sr2RuO4 with Ru inclusions nucleates superconductivity at the interface between Ru and Sr2RuO4. The structure of the interface state and its physical properties are examined here. Two superconducting phases are identified between the transitions to the bulk phase at 1.5K and to the 3K phase. The nucleation of the 3K phase results in a state conserving time reversal symmetry, which generates an intrinsically frustrated superconducting network in samples with many Ru inclusions. At a lower temperature (>1.5K), a discontinuous (first order) transition to an interface state breaking time reversal symmetry is found leading to an unfrustrated network phase. It is shown that this phase transition located at a temperature between 1.5 and 3K would yield the anomalous property that the critical current in such a network depends on the sign of the current, reproducing recent experimental observations.Comment: This paper has been withdrawn by the authors. 5 pages, 6 figure

Ferromagnetism Induced by Uniaxial Pressure in the Itinerant Metamagnet Sr3Ru2O7

We report a uniaxial-pressure study on the magnetisation of single crystals of the bilayer perovskite Sr3Ru2O7, a metamagnet close to a ferromagnetic instability. We observed that the application of a uniaxial pressure parallel to the c-axis induces ferromagnetic ordering with a Curie temperature of about 80 K and critical pressures of about 4 kbar or higher. This value for the critical pressure is even higher than the value previously reported (~ 1 kbar), which might be attributed to the difference of the impurity level. Below the critical pressure parallel to the c-axis, the metamagnetic field appears to hardly change. We have also found that uniaxial pressures perpendicular to the c-axis, in contrast, do not induce ferromagnetism, but shift the metamagnetic field to higher fields.Comment: Accepted for publication in Proc of 24th Int.

Medical Libraries of Tomorrow: Exploring New Acquisition Methods for E-Textbook Reference Collection Titles

Objective: Acquiring new individual e-textbook titles at the Florida International University (FIU) Herbert Wertheim College of Medicine (HWCOM) Medical Library: The current method needs to be reconsidered? Introduction: The Course Textbook Reference Collection has annually prepared for HWCOM programs based on the course textbook lists from each program coordinator. Librarians are always required to first look for textbooks in an electronic format: HWCOM Library = Nearly 100% digital Limited space for print copies Clinical teaching sites -across the South Florida region However, searching a specific e-book title is challenging. Methods: A review and analysis of e-textbook acquisition activity records from the past two academic years (2017-2018 and 2018-2019)
