WE INTER-ARE: THE PANDEMIC CHALLENGE REDEFINING HUMANS AND COMMUNITIES by K. Abraham

“… The COVID-19 pandemic calls for a critical introspection into our way of being human in relation to other forms of life on this planet. Given that social hierarchies attribute higher and lower status to human beings based on their race, class, caste and gender identity, and legitimise the exploitation of other human beings and the earth, re-thinking our hierarchical positioning as “masters” of this universe becomes imperative. …”

Strength Analysis of Planetary Gear Train of A New Shearer Cutting Unit by Zhao Lijuan, Qiao Meina, Lan Jinbao

“…Taking the planetary gear train in a new type of thin seam shearer cutting part as the research object,based on multi-body dynamics theory,the rigid-flexible coupled model of the shearer cutting part is established,and the dynamic simulation analysis is carried on,the stress and deformation of the planetary gear train parts are obtained.The structure improvement of the sun wheel and planet carrier is carried out,the maximum mesh stress on sun wheel tooth surface is decreased by423.26 MPa after improvement,the stress concentration phenomenon on planet carrier is basically eliminated,the fatigue life is improved to 8.302 2×107 times.The research methods provides a quantitative basis for the design of planetary gear train,reduces the development cost in the process of production,improves the benefit of enterprise.…”

Analyzing Black Hole Super-Radiance Emission of Particles/Energy from a Black Hole as a Gedankenexperiment to Get Bounds on the Mass of a Graviton by A. Beckwith

“…Use of super-radiance in BH physics, so dE/dt<0 specifies conditions for a mass of a graviton being less than or equal to 1065 grams, allows for determing what role additional dimensions may play in removing the datum that massive gravitons lead to 3/4th the bending of light past the planet Mercury. The present document makes a given differentiation between super-radiance in the case of conventional BHs and Braneworld BH super-radiance, which may delineate whether Braneworlds contribute to an admissible massive graviton in terms of removing the usual problem of the 3/4th the bending of light past the planet Mercury which is normally associated with massive gravitons. …”

Simulation and Analysis of Oil Churning Power Loss in Electric Drive Planetary Gears Based on the CFD Method by Tang Pei, Wang Le, Ren Shaoying, Li Shanshan

“…The splash lubrication of the two-stage planetary gear drive is simulated by computational fluid dynamics (CFD) software and C language user defined function (UDF), and the visualization of oil gas two-phase transient flow field is realized; by extracting the surface pressure and the viscous force, the churning loss of the sun gears, planet gears and planet carriers are obtained; the simulation and analysis of the 25 working conditions show that the churning loss varies with the immersion depth and speed; the results show that the oil churning power loss increases with the oil immersion depth and the speed, and there is no obvious inflection point. …”

Magnetized Protoplanetary Disks around Young Stars in the Presence of Realistic Cooling by Hanifeh Ghanbarnejad, Maryam Ghasemnezhad

“…Additionally, we calculated the cooling timescale in our model to assess one possible fragmentation condition necessary for planet formation. Our results indicate that, although the gravitational instability condition exists in the midplane of the disk, the cooling timescale is not short enough ( τ _cool  ≈ 1000Ω ^−1 ), and one possible mechanism for planet formation is not met.…”
