Mineral profiles of wines and soil extracts were analysed in the five most popular international wines (Cabernet Sauvignon, Syrah, Merlot, Cot, and Tannat) and national Boğazkere, which is one of...
Mineral profiles of wines and soil extracts were analysed in the five most popular international wines (Cabernet Sauvignon, Syrah, Merlot, Cot, and Tannat) and national Boğazkere, which is one of...
The elemental composition of marine cyanobacteria is an important determinant of the ecological stoichiometry in low-latitude marine biomes. We analyzed the cellular carbon (C), nitrogen (N), and phos...
Estimation of 26Al (half-life = 705 kyr) content at the time of meteorite fall is required to calculate the terrestrial age of meteorites using the 26Al content. Previous studies (e.g., Cressy, 1971;...
The chemical element composition of dust particles was characterized by the ground-based samples collected at Beijing in the spring of 2004. Most of mineral and pollutant element concentrations in pa...
Instrumental neutron activation analysis has been applied for the determination of up to 40 elements in waters from eleven Norwegian rivers. In order to represent the composition of an average river...
Rapid industrialization and economic take-off in coastal cities of China have placed great strain on the environment. In the this study, 40 aerosol samples were collected in the coast of Xiamen, Fujia...
The chemical composition of secondary organic aerosol (SOA) particles, formed by the dark ozonolysis of α-pinene, was characterized by a high-resolution time-of-flight aerosol mass spectrometer. The e...
A Berner low pressure impactor was used to collect size-segregated aerosol samples at Finokalia, located on the north-eastern coast of Crete, Greece during July 2000 and January 2001. Several samples ...
The maturation of spermatozoa in the epididymis is dependent upon the presence of androgens. This study examined the effects of androgen suppression by estradiol valerate on the elemental compositio...
The aim of this study was to assess the elemental composition of the brazing alloy of representative orthodontic brackets. The brackets examined were Gemini (3M, Unitec, Monrovia, Calif), MicroLoc...
With the aim to determine the contribution of development and reproduction to the variability in the elemental composition of zooplankton, we measured the carbon (C), hydrogen (H), nitrogen (N), and ...
We measured the elemental composition of single cells from six strains of marine Prochlorococcus and two strains of marine Synechococcus by X-ray microanalysis in the transmission electron microscope ...
The effects of nutrient ratios on algal community structure and algal growth have been examined extensively in lakes and marine environments, but rarely in streams. We manipulated stream water N : P ...
Blooms of the marine diatom Skeletonema costatum were initiated in closed-system batch cultures with P-deficient medium under two different initial concentrations of dissolved molecular CO2([CO2,aq]: ...
