In order to study the damage mechanism of fissure-grouted rocks in abandoned mine pumped storage, uniaxial compression tests were conducted using rock specimens after dry and wet cycles. Additionally, acoustic emission sensors used track specimens. The results demonstrate a negative correlation between peak strength elastic modulus linear decrease wave velocity mechanical characteristics fractu...

BACKGROUND Numerous malaria epidemics have occurred in western Kenya, with increasing frequency over the past 20 years. A variety of hypotheses on the etiology of these epidemics have been put forth, with different implications for surveillance and control. We investigated the ecological and socioeconomic factors promoting highland malaria vectors in the dry season after the 2002 epidemic. ME...

There are large discrepancies among estimates of the cropland area in China due to the lack of reliable data. In this study, we used Landsat TM/ ETM data at a spatial resolution of 30 m to reconstruct spatial and temporal patterns of cropland across China for the time period of 1990–2000. Our estimate has indicated that total cropland area in China in 2000 was 141.1 million hectares (ha), inclu...

In this study the quantification of biomass within all relevant compartments of a three-year-old poplar clone (P. maximowicii × P. trichocarpa) planted on abandoned agricultural land at a density of 5000 trees ha −1 is presented. A total of 30 trees within a diameter range of 1.8 cm to 8.9 cm, at breast height (dbh at 1.3 m), were destructively sampled. In order to analyze the biomass, the comp...
