The objectives of the experiment were to study nitrogen fractions of the Cornell Net Carbohydrate and Protein System (CNCPS) and digestibility of organic matter (OMD) and crude protein (CPD) along wit...
The fucoidans were obtained by extraction with water and gradient precipitation with different concentrations of ethanol. The main structural characterisations and bioactivities were achieved. Four fr...
Concentrations of acid volatile sulfides (AVS) as metal sulfides in three different size fractions (<30 nm, 30–200 nm, >200 nm) at Lake Teganuma were measured using a nano-filtration followed by a pu...
We report the origin of significant fractionation of Pb isotope ratios in Ca-doped 0.08 mol L–1 HNO3 solutions. We applied Tl-spiked standard bracketing mass fractionation correction using solution-b...
A new method for determining the relative Faraday cup efficiency (RFCE) for nine Faraday cups has been developed using 86Sr, 87Sr, and 88Sr isotope signals, and the exponential mass fractionation law...
Efforts to improve the cure rates of advanced squamous cell carcinoma of the head and neck cancer have been made by altering the dose and fractionation schedules for radiation treatment in an attempt...
Understanding stable isotope fractionation in trophic networks is important for the interpretation of stable isotope composition of ecosystem components. This work explores the influence of grazing pr...
Four groups of antibiotic activity compounds were separated and purified from the ethyl acetate fraction of a broth culture of Streptomyces herbaricolor HNS2-2.Trace analyses were performed and anti-m...
Pinched flow fractionation is shown to be an efficient and selective way to quickly separate particles by size in a very polydisperse semi-concentrated suspension. In an effort to optimize the method,...
To elucidate the isotope geochemistry of CH4 production in deep subsurface environments, we investigated the relation between H2 concentration and hydrogen and carbon isotope fractionation by CO2 red...
Abstract: The mass-dependent equilibrium stable isotope fractionation between different materials is an important geochemical process. Here we present an efficient method to compute the isotope fracti...
The mass-dependent equilibrium stable isotope fractionation between different materials is an important geochemical process. Here we present an efficient method to compute the isotope fractionation be...
Theoretical and experimental aspects of oxygen isotope fractionation in carbonate minerals are critically examined based on a direct comparison of fractionation factors for carbonate-water systems. T...
Within neutrally buoyant hydrothermal plumes derived from the Yonaguni Knoll IV hydrothermal field (24°51′N, 122°42′E, D = 1,370-1,385 m) in the southwestern Okinawa Trough back-arc basin, we obtained...
The BCR sequential extraction and EDTA single extraction method were applied to study the fractionation, concentration and bioaccessibility of the heavy metals in the sediment of Fenhe reservoir in No...
