Microscopic organism plays a big role in ocean carbon cycling, Scripps scientists discover
Microscopic organism big role ocean carbon cycling Scripps scientists discover
2014/5/13
It’s broadly understood that the world’s oceans play a crucial role in the global-scale cycling and exchange of carbon between Earth’s ecosystems and atmosphere. Now scientists at Scripps Institution ...
Prior Upper Body Exercise Reduces Cycling Work Capacity but Not Critical Power
POWER–DURATION RELATIONSHIP METABOLITES ARM CRANKING CYCLING
2017/5/19
This study examined whether metabolite accumulation, induced by prior upper body exercise, affected the power–duration relationship for leg cycle ergometry.
Trace metal cycling in the deep water of the South China Sea: The composition, sources, and fluxes of sinking particles
Trace metal cycling in the deep water the South China Sea composition sources fluxes of sinking particles
2014/4/8
Moored sediment traps were deployed for 1 yr at depths of 120, 600, and 3500 m in the water column to investigate the trace metal (M) (Al, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn) composition, sources, ...

Project X Rapid Cycling Dual Storage Superconducting Synchrotrons Accelerator Physics
2012/5/29
Investigation of neutrino oscillations and rare meson decays are main physics goals of Project X. The successful physics outcome relies on the feasibility of high-intensity neutrino and meson (K+ and ...
Seasonal change in microbial sulfur cycling in monomictic Lake Fukami-ike, Japan
Seasonal change microbial sulfur cycling monomictic Lake Fukami-ike Japan
2014/4/4
Sulfur budgets and seasonal progression of sulfur cycling processes were investigated in Lake Fukami-ike, a small monomictic lake in Japan. The sulfur isotopic mass balance shows that the main sulfur ...

Stability of Mg-sulphate minerals in the presence of smectites: Possible mineralogical controls on H2O and nutrient cycling on Mars
Stability Mg-sulphate minerals presence of smectites mineralogical controls H2O nutrient cycling Mars
2012/3/30
Hydrated sulphate minerals, including kieserite (MgSO4·H2O), gypsum (CaSO4·2H2O), and bassanite (CaSO4·~0.5H2O), have been detected on Mars (Gendrin et al., 2005; Wray et al., 2010), and polyhydrated ...
Characterization of alkaline phosphatase activity in the North and South Pacific Subtropical Gyres: Implications for phosphorus cycling

2014/4/8
We characterized alkaline phosphatase (AP) activity (APA) and report AP kinetic parameters in the North and South Pacific Subtropical Gyres (NPSG and SPSG, respectively) to evaluate the relative impor...
Jackknife and bootstrap with cycling blocks for the estimation of fractional parameter in ARFIMA model
Jackknife bootstrap fractionally parameter ARFIMA model moving blocks non overlapping blocks
2011/4/6
One of most important problems concerning the ARFIMA time series model is the estimation of fractional parameter d. Various methods have been used to solve this problem, such as the log-periodogram r...
Dynamical behavior of a plant-herbivore system with nutrient cycling in a polluted habitat
Plant Herbivore Pollutant
2010/9/21
In this paper, a mathematical model is proposed to study the effect of pollutant on the existence of plant-herbivore system with nutrient cycling. The deterministic mathematical model is formulated us...
