Reentrant phase transitions of higher-dimensional AdS black holes in dRGT massive gravity

We study the $P-V$ criticality and phase transition in the extended phase space of anti-de Sitter (AdS) black holes in higher-dimensional de Rham, Gabadadze and Tolley (dRGT) massive gravity, treating the cosmological constant as pressure and the corresponding conjugate quantity is interpreted as thermodynamic volume. Besides the usual small/large black hole phase transitions, the interesting thermodynamic phenomena of reentrant phase transitions (RPTs) are observed for black holes in all $d\geq6$-dimensional spacetime when the coupling coefficients $c_i m^2$ of massive potential satisfy some certain conditions.Comment: 14 pages, several references are added, v2: published in EPJ

Reentrant phase transitions and triple points of topological AdS black holes in Born-Infeld-massive gravity

Motivated by recent developments of black hole thermodynamics in de Rham, Gabadadze and Tolley(dRGT) massive gravity, we study the critical behaviors of four-dimensional topological Anti-de Sitter(AdS) black holes in the presence of Born-Infeld nonlinear electrodynamics by treating the cosmological constant as pressure and the corresponding conjugate quantity is interpreted as thermodynamic volume. It shows that besides the Van der Waals-like SBH/LBH phase transitions appears, the so-called reentrant phase transitions (RPTs) are also observed when the coupling coefficients $c_i m^2$ of massive potential and Born-Infeld parameter $b$ satisfy some certain conditions.Comment: arXiv admin note: text overlap with arXiv:1612.08056; text overlap with arXiv:1402.2837, arXiv:1306.5756 by other autho

China's Regional Feedgrain Markets: developments and prospects

This report provides the Australian grains industry with an in-depth understanding of China's feedgrain markets at both the regional and national levels. It also provides useful information to other Australian industries whose businesses are related to the use of feedgrains and who ,have an interest in the Chinese market such as livestock, pulses and feed industries. In recent years, China's demand for feedgrain has been increasingly recognised as an important issue and many believe that any future increase in total grain demand in China will be mainly caused by an increasing demand for feedgrains. On the other hand, it seems that, in the longer term, China will Dot be able to supply enough feedgrains with its domestic resources. As a major grain exporter. it is essential for Australia to gain improved understanding of China's feedgrain market developments and prospects. It is for this important reason that GRDC supported this project (GRDC Project Number US282) to look into China's feedgrain issues

Evolving trends of grain production in China

Grain is China’s most significant agricultural product, its output being the most watched indicator by government officials, traders and researchers inside and outside China. This paper looks into China’s grain production trends in the recent decade, both before and after China’s WTO accession. It examines changes in total grain output, grain crop composition, regional distribution of grain production, and also changes in production technologies and costs. The paper concludes by addressing a number of emerging issues that are likely to affect future grain production in China
