Mathematical Modeling of the Kinematic Scheme Planetary Mixer Mechanism
Proceedings of the International Conference on Applied Innovations in ITPlanetary mixer is presented, which uses drive mechanisms for the working bodies of the mortar mass mixture of a construction mortar mixer. The main objective of the study is to create a mathematical model in the mortar mixer mechanism of three different

Evidence for a planetary mass third body orbiting the binary star KIC 5095269 [PDF]
, 2017 In this paper, we report the evidence for a planetary mass body orbiting the close binary star KIC 5095269. This detection arose from a search for eclipse timing variations among the more than 2,000 eclipsing binaries observed by Kepler.

Advanced Functional Materials, EarlyView.This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

Convective Mixing in Gas Giant Planets with Primordial Composition Gradients
The Astrophysical JournalLinking atmospheric measurements to the bulk planetary composition and ultimately the planetary origin is a key objective in planetary science. In this work, we identify the cases in which the atmospheric composition represents the bulk composition.

Quantifying the Impact of the Dust Torque on the Migration of Low-mass Planets
The Astrophysical Journal, 2023 Disk solids are critical in many planet formation processes; however, their effect on planet migration remains largely unexplored. Here we assess this important issue for the first time by building on the systematic measurements of dust torques on an ...

A Search for Photometric Variability in the Young T3.5 Planetary-mass Companion GU Psc b [PDF]
, 2017 We present a photometric J-band variability study of GU Psc b, a T3.5 co-moving planetary-mass companion (9–13 ) to a young (∼150 Myr) M3 member of the AB Doradus Moving Group. The large separation between GU Psc b and its host star (42″) provides a rare

Filling Factors and Ionized Masses of Planetary Nebulae [PDF]
Symposium - International Astronomical Union, 1993 We present a study on the filling factors and ionized masses of four sets of galactic and extra–galactic planetary nebulae (PNe) at known distances. The calculation of filling factors and ionized masses has been pursued as to get a deeper insight on the evolution of this class of objects.

A Termite‐Inspired Alternative to Cement
Advanced Functional Materials, EarlyView.A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,
