Abnormal Litter Induced by Typhoon Disturbances Had Higher Rates of Mass Loss and Carbon Release than Physiological Litter in Coastal Subtropical Urban Forest Ecosystems
abnormal litter carbon cycle coastal urban forest litter decomposition physiological litter tropical cyclones
2023/11/22
The decomposition of abnormal litter caused by extreme weather events might play an increasingly important role in carbon and nutrient cycling in forest ecosystems under climate change scenarios, whic...
Relation between mealtime distribution of protein intake and lean mass loss in free-living older adults of the NuAge study
dietary protein aging lean mass muscle mass sarcopenia elderly nutrition
2018/12/14
Background: Studies have shown that an even protein intake distribution across meals increased 24-h muscle protein synthesis in young adults compared with a skewed intake. Whether this short-term resu...
Higher compared with lower dietary protein during an energy deficit combined with intense exercise promotes greater lean mass gain and fat mass loss: a randomized trial
athlete dietary protein leucine skeletal muscle resistance exercise high-intensity interval training
2018/11/28
Background: A dietary protein intake higher than the Recommended Dietary Allowance during an energy deficit helps to preserve lean body mass (LBM), particularly when combined with exercise.

Circumstellar gas and dust emission and mass loss from evolved stars
Orbiting a star Gas Dust emissions Evolution of stars
2014/12/9
This dissertation presents a study of the circumstellar gas and dust emission and their relation to the mass-loss in evolved stars. Considering the physical process of heating and cooling of the dust,...
Dust driven mass loss from carbon stars as function of stellar parameters - II. Effects of grain size on wind properties
AGB and post-AGB – Stars: atmospheres – Stars: carbon – Stars: circumstellar matter – Stars: evolution – Stars: mass loss –2 Hydrodynamics – Radiative transfer
2011/9/30
In this paper we explore grain size effects on wind properties of carbon stars, using a generalized description of radiative cross sections valid for particles of arbitrary sizes. The purpose of the s...
Mass Loss, Destruction and Detection of Sun-grazing and -impacting Cometary Nuclei
comet sun impact sun-grazing radiation collisions
2011/9/30
Incoming sun-grazing comets almost never re-emerge, but no final destruction event has ever been observed, nor sun-impactor destruction theory developed. We seek analytic models of comet nucleus destr...
The mass-loss rates of red supergiants and the de Jager prescription
The mass-loss rates of red supergiants the de Jager prescription
2011/1/11
Mass loss of red supergiants (RSG) is important for the evolution of massive stars, but is not fully explained. Several empirical prescriptions have been proposed, trying to express the mass-loss rate...
Fuel Efficient Galaxies: Sustaining Star Formation with Stellar Mass Loss
cosmology theory – galaxies evolution – galaxies formation – stars formation – methods
2010/11/11
We examine the importance of secular stellar mass loss for fueling ongoing star formation in disk galaxies during the late stages of their evolution. For a galaxy of a given stellar mass, we calculate...
A possible solution to the mass-loss problem in M-type AGB stars
mass-loss problem M-type AGB stars
2010/11/12
Mass loss is a fundamental, observationally well-established feature of AGB stars but many aspects of this process still remain to be understood. To date,self-consistent dynamical models of dust-drive...
The mass-loss rates and molecular abundances of S-type AGB stars
mass-loss rates molecular abundances of S-type AGB stars
2010/11/12
The S-type stars are believed to have a C/O-ratio close to unity (within a few percent). They are considered to represent an intermediate evolutionary stage as AGB stars evolve from oxygen-rich M-type...
Abundance anomalies in pre-main-sequence stars: Stellar evolution models with mass loss
Diffusion — stars chemically peculiar — stars mass–loss — stars pre–main-sequence — stars evolution — stars
2010/11/12
Aims. The effects of atomic diffusion on internal and surface abundances of A and F pre–main-sequence stars with mass loss are studied in order to determine at what age the effects materialize, as wel...
Mass loss rates inferred from mid-IR color excesses of LMC and SMC O stars
