Numerical study on the applicability to manufacturing of contact-stress-optimised shaft-hub connections joined by lateral extrusion

open access: yesManufacturing Review, 2020
Shaft-hub connections, which are joined by plastic deformation of at least one component (e.g. joining by lateral extrusion), can meet today's contradictory requirements for high power densities with low manufacturing costs.

Vortex cooled air turning of induction-hardened raceway on the wind turbine-bearing ring

open access: yesTehnički Glasnik, 2019
In the turning process of hard materials with CBN cutting inserts, metalworking fluid is not advisable as it results in poorer quality of finished surface and shortening of the tool life.

Distinct Bacterial Communities Associated with Massive and Branching Scleractinian Corals and Potential Linkages to Coral Susceptibility to Thermal or Cold Stress

open access: yesFrontiers in Microbiology, 2017
It is well known that different coral species have different tolerances to thermal or cold stress, which is presumed to be related to the density of Symbiodinium. However, the intrinsic factors between stress-tolerant characteristics and coral-associated

Tolerance to Environmental Stresses

open access: yes, 2021
Salinity imposes constraints on plant growth and development. Efforts have been made to develop salt-tolerant crops by different methods, the outcomes have not yet been sufficiently satisfactory. Plants depend on their symbiotic partners such as fungal symbionts to cope with stress conditions such as salinity. Bittersweet nightshade (Solanum dulcamara)

The Forkhead Box Gene, MaSep1, Negatively Regulates UV- and Thermo-Tolerances and Is Required for Microcycle Conidiation in Metarhizium acridum

open access: yesJournal of Fungi
Insect pathogenic fungi have shown great potential in agricultural pest control. Conidiation is crucial for the survival of filamentous fungi, and dispersal occurs through two methods: normal conidiation, where conidia differentiate from mycelium, and ...
