The Soil Aggregates and Associated Organic Carbon across the Greater Khingan Mountains: Spatial Patterns and Impacting Factors
Greater Khingan Mountains forest soils soil aggregates soil organic carbon spatial variation
2023/12/1
1) Background: The preservation of soil organic carbon (SOC) by soil aggregates (SA) is a key mechanism for the stability of the soil carbon (C) pool. (2) Methods: Soil samples were collected at a 0–2...
Labile forms of carbon and soil aggregates
ecosystem labile carbon macro-aggregates soil type
2016/8/2
Soil organic matter (SOM) plays an important role in the soil aggregation and vice versa, its incorporation into the soil aggregates is one of the mechanisms of soil organic carbon stabilization. In t...
Studies of Crystalline Aggregates of Pheophorbide and Bacteriopheophorbide by Electro-Absorption (Stark Effect) Spectroscopy and Powder X-ray Diffraction
GYROTRON 2ND HARMONIC SUBMILLIMETER WAVE
2016/5/23
Absorption and electro-absorption (Stark effect) spectra of polycrystalline and lyophillized samples of pheophorbides and bacteriopheophorbides have been measured in order to obtain information on the...
Numerical simulations of collisional disruption of rotating gravitational aggregates:Dependence on material properties
Asteroids Planetesimals Dynamics N-body simulations Collisional physics
2015/12/25
Our knowledge of the strengths of small bodies in the Solar System is limited by our poor understanding of their internal structures, and this, in turn, clouds our understanding of the formation and e...
ROTATION-DEPENDENT CATASTROPHIC DISRUPTION OF GRAVITATIONAL AGGREGATES
minor planets asteroids:general planets and satellites:formation planets and satellites:physical evolution
2015/12/25
We carry out a systematic exploration of the effect of pre-impact rotation on the outcomes of low-speed collisions between planetesimals modeled as gravitational aggregates. We use pkdgrav, a cosmolog...
Asteroids:equilibrium shapes of rotating gravitational aggregates
Asteroids shapes–Numerical simulations–Solar System evolution
2015/12/25
Many evidences lead us to think that a significant portion of asteroids are aggregates of boulders kept together by gravity, with little or no contribution from cohesive forces. The standard hydrodyna...
Numerical simulations of asteroids modelled as gravitational aggregates with cohesion
Asteroid structure Asteroid dynamics Asteroid satellites Collisional physics Impact processes
2015/12/25
Evidence is mounting that asteroids larger than a few hundred metres in diameter are gravitational aggregates of smaller, cohesive pieces. For example, images of 25143 Itokawa show aboulder-strewn sur...
A steady-state model of NEA binaries formed by tidal disruption of gravitational aggregates
Asteroids dynamics Satellites of asteroids
2015/12/25
We present results of a simulation of a steady-state binary near-Earth asteroid (NEA) population. This study combines previous work on tidal disruption of gravitational aggregates [Walsh, K.J., Richar...
Super-resolution fluorescence of huntingtin reveals growth of globular species into short fibers and coexistence of distinct aggregates.

2015/12/11
Polyglutamine-expanded huntingtin, the protein encoded by HTT mutations associated with Huntington's disease, forms aggregate species in vitro and in vivo. Elucidation of the mechanism of growth of fi...
Water Stability of Soil Aggregates in Different Systems of Tillage
conventional tillage shallow disking soil structure
2015/7/28
The influence of various agrotechnical measures on macrostructural changes in topsoil and subsoil was studied
in the course of a four-year experiment. Macrostructure was evaluated according to the a...
Stability of soil aggregates and their ability of carbon sequestration
water-stable aggregates soil organic matter vineyards
2015/3/10
One of the most important binding agents for forming stable aggregates is a soil organic matter (SOM), which can be retained in various size fractions of aggregates. If aggregates are water-resistant,...
TROPICAL FOREST CHANGE ASSESSMENT: THE USE OF AGGREGATES, A SEMANTIC APPROACH

2015/2/4
Assessing land cover changes in tropical rain forest areas is an issue of worldwide importance. Multi-spectral, higher
spatial resolution satellite data are often the only data source for generating ...
Soft spheres interacting via a hard core and a range of attractive and repulsive ‘soft-shoulder’ potentials self-assemble into clusters forming a variety of mesophases. We combine a mean-field theory ...
