Elemental composition of marine Prochlorococcus and Synechococcus: Implications for the ecological stoichiometry of the sea
Elemental composition marine Prochlorococcus Synechococcus ecological stoichiometry
2014/5/21
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...
Simple relationship between 26Al production rate and major elemental composition of meteorite samples
production rate 26Al terrestrial age howardite eucrite
2017/4/11
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 Elemental Composition of Atmospheric Particles at Beijing during Asian Dust Events in Spring 2004
Dust Chemical element composition Asian dust event
2016/3/29
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...
Seasonal variations in elemental composition of aerosols in Xiamen, China
environmental change aerosol concentration seasonal variation enrichment factor deposition flux
2017/8/9
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...
Loading-dependent elemental composition of α-pinene SOA particles
Loading-dependent elemental composition α-pinene SOA particles
2009/3/13
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...
Size resolved mass concentration and elemental composition of atmospheric aerosols over the Eastern Mediterranean area
Size resolved mass concentration elemental composition atmospheric aerosols Eastern Mediterranean area
2009/3/11
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 ...
Reproduction as one of the main causes of temporal variability in the elemental composition of zooplankton
Reproduction temporal variability
2014/5/13
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 ...
Elemental composition of single cells of various strains of marine Prochlorococcus and Synechococcus using X-ray microanalysis
Elemental composition single cells various strains marine Prochlorococcus Synechococcus X-ray microanalysis
2014/5/21
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 ...
Effects of N : P ratio and total nutrient concentration on stream periphyton community structure, biomass, and elemental composition
total nutrient concentration elemental composition
2014/5/30
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 ...
