The Solar Nebula on Fire: A Solution to the Carbon Deficit in the Inner Solar System

open access: yes, 2010
Despite a surface dominated by carbon-based life, the bulk composition of the Earth is dramatically carbon poor when compared to the material available at formation.

Determining the Maximum Linear Mass of a Suspended Conveyor Belt Using PySR Symbolic Regression

open access: yesMining
Suspended conveyor belts are widely used in mining, including in systems with non-contact support such as magnetically suspended conveyors, where the maximum admissible linear mass of the loaded belt determines the required supporting forces.

Belts and Suspenders: Interactions Among Climate Policy Regulations [PDF]

open access: yes, 2010
With few exceptions, economic analyses of "cap-and-trade" permit trading mechanisms for climate change mitigation have been based on first-best scenarios without pre-existing distortions or regulations. The reason is obvious: interactions between permit trading and other regulations will be complex. However, climate policy proposed for the U.S.

Specifics of determining the forces are applied to the suspensions of conveyor with suspended belt and distributed drive, depending on their spatial configuration on the route [PDF]

open access: yesНаучно-технический вестник Брянского государственного университета, 2015
The basic version of the route, which includes the main areas of transportation of conveyor with suspended belt and distributed drive, was reviewed. Action of the suspension on respective areas, which occurs at moving of their, was ana-lyzed.

Aeolian Prokaryotic Communities of the Global Dust Belt Over the Red Sea

open access: yesFrontiers in Microbiology, 2020
Aeolian prokaryotic communities (APC) are important components of bioaerosols that are transported freely or attached to dust particles suspended in the atmosphere. Terrestrial and marine ecosystems are known to release and receive significant prokaryote

Electrohydrodynamic deformation and rotation of a particle-coated drop

open access: yes, 2015
A dielectric drop suspended in conducting liquid and subjected to an uniform electric field deforms into an ellipsoid whose major axis is either perpendicular or tilted (due to Quincke rotation effect) relative to the applied field.

Cadmium transport in sediments by tubificid bioturbation: An assessment of model complexity [PDF]

open access: yes, 2006
Biogeochemistry of metals in aquatic sediments is strongly influenced by bioturbation. To determine the effects of biological transport on cadmium distribution in freshwater sediments, a bioturbation model is explored that describes the conveyor-belt ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Comparison of bungee-aided and free-bouncing accelerations on trampoline [PDF]

open access: yes, 2019
Trampolines remain the single best apparatus for the training of aerial acrobatics skills. Trampoline use has led to catastrophic injuries from poor landings.
