A decline in soil quality is a major factor contributing to the degradation of forest ecological function. Vegetation plays a vital role in maintaining soil quality; however, the influence of plantati...
Macroscopic Observability of Spinorial Sign Changes under 2pi Rotations
Topology of Space Rotational Symmetry Rotation Group Bell's theorem Local Realism Local Causality Quantum Correlation
2016/6/12
The question of observability of sign changes under 2pi rotations is considered. It is shown that in certain circumstances there are observable consequences of such sign changes in classical physics. ...

DETECTING CROP ROTATIONS IN CHINA USING AVHRR IMAGERY AND ANCILLARY DATA
Land use Crop Detection Classification Imagery Multitemporal
2015/7/29
The situation of cropland use in China is very complicated. In many areas, the cropland is used in multi-cropped ways. There is a
need for better information on the area and distribution of cropland...
Effects of broad-leaf crop frequency in various rotations on soil organic C and N, and inorganic N in a Dark Brown soil
Broad-Leaf Crops Canola Frequency Light Fraction Organic C
2013/3/4
The objective of this study was to determine the impact of frequency of broad-leaf crops canola and pea in various crop rotations on pH, total organic C (TOC), total organic N (TON), light fraction or...
Cereal-forage crop rotations and irrigation treatment effect on water use efficiency and crops sustainability in Mediterranean environment
Alfalfa Binary Mixture Durum Wheat lrrigation
2013/2/27
Agricultural systems based on crop rotations favour sustainability of cultivation and productivity of the crops. Wheat-forage crops rotations (annual winter binary mixture and perennial alfalfa meadow...
Nematode infestation and N-effect of legumes on soil and crop yelds in legume-sorghum rotations
Legume Nematode Nitrogen Crop Rotation Sorghum
2013/3/4
The effects of cowpea (Vignaunguiculata) and-groundnut (Arachis hypogea) on succeeding sorghum yields, soil mineral N and nematode infestationwere studied during five cropping seasons (2000 to 2004) i...
Influence of Rotations on the Critical State of Soil Mechanics
Influence of Rotations Critical State of Soil Mechanics
2010/11/25
The ability of grains to rotate can play a crucial role on the collective behavior of granular media. It has been observed in computer simulations that imposing a torque at the contacts modi es the fo...
Quantum dot Rabi rotations beyond the weak exciton-phonon coupling regime
Quantum dot Rabi rotations weak exciton-phonon coupling regime
2010/10/21
We study the excitonic dynamics of a driven quantum dot under the influence of a phonon
environment, going beyond the weak exciton-phonon coupling approximation. By combining the
polaron transform a...
Exponential Riesz bases, discrepancy of irrational rotations and BMO
Exponential Riesz bases discrepancy of irrational rotations BMO
2010/12/3
Matei and Meyer proved that ‘simple quasicrystals’ are universal sets of sampling and interpolation for signals with a band-limited spectrum. We ask if the corresponding exponential system is a univer...
Testing Miocene Remagnetization of Bey Dağları: Timing and Amount of Neogene Rotations in SW Turkey
Aegean orocline palaeomagnetism IRM component analysis remagnetization
2010/10/14
Here we reassess the timing and amount of rotation of the eastern limb of the Aegean orocline, located in SW Turkey. The current model for this orocline involves a 25-30° counterclockwise (CCW) rotati...
Flow Induced by Non-coaxial Rotations of a Disk and the Fluid at Infinity with Nearly the Same Angular Velocity
Disk Fluid at Infinity Non-coaxial Rotation Viscous Fluid
2009/10/13
In this paper, the flow of a viscous fluid due to the non-coaxial rotations of a disk and the fluid at infinity with a slight angular velocity di erence is studied. The e ect of angular velocity diffe...
Rotations in the Space of Split Octonions
Nonassociative algebras Rotations Split Octonions
2009/9/4
The geometrical application of split octonions is considered. The new representation of products of the basis units of split octonionic having David's star shape (instead of the Fano triangle) is pres...
