The asteroid impact 66 million years ago that ushered in a mass extinction and ended the dinosaurs also killed off many of the plants they relied on for food. Fossil leaf assemblages from Patagonia su...
The radioisotope pollution shows two types of patterns: dry and wet deposits for nuclear power plant accidents. Two surface pollution patterns were analysed by fractal. In Fukushima nuclear power pl...
Deltaic sediments of the Mekong River delta sampled from a tidal beach in Vietnam during the wet season (late October 2011) showed strong 137Cs and 134Cs activities reflecting radionuclides released ...
We present our April to December 2011 observations of 134Cs and 137Cs activities in surface water at Hasaki, a coastal station 180 km south of the Fukushima Dai-ichi Nuclear Power Plant (FNPP1) accid...
We present a numerical study carried out with the SPRINTARS model modified to account for the radioactive decay of 35S compounds emitted from the Fukushima Daiichi nuclear power plant station after th...
Concentrations of the radionuclides, U, Pu, and Cs were measured in water samples (10–20 L) to study analyte dispersion and migration following the Fukushima Daiichi Nuclear Power Plant (FDNPP) accid...
The Fukushima Dai-ichi Nuclear Power Plant (DNPP) accident has caused serious contamination of the marine environment from atmospheric fallout deposition and the direct discharges of highly radioacti...
Wildfires and prescribed fires burn many thousand of hectares of forest annually (Ulery et al., 1996). The intensity of forest burning is related to weather conditions, amount of fuel available and th...
The niche breadths and niche overlaps of Selaginella pulvinata and of other several main species of the herbaceous layer were measured at the barren hillsides in the arid valley of the upper reach of ...
To determine the accuracy and precision limits associated with carbon stable isotope ratio (δ13C) measurements of cellulose and lignin from plant samples, experiments were performed using differing e...
ABSTRACT: Design and synthesis of the agricultural and ecological superabsorbent materials with cost-efficient and fertilizer-release characteristics has recently attracted considerable interests. In ...
While in cement industry alternative fuels have been widely used for 15 years, it is still considered as a pioneering application in lime manufacturing. Reasons are both technical and environmental.
