On Caputo fractional Bertrand Curves in E3 and E31

open access: diamondFilomat
In this article, we examine Bertrand curves in E3 and E31 by using the Caputo fractional derivative which we call ?-Bertrand Curves. First, we consider ?-Bertrand curves in E3 and we give a characterization of them. Then, we study ?-Bertrand curves in E31 and we prove the necessary and sufficient condition for a ?-Bertrand curves in E31 by ...

Slant helices in Minkowski 3-space E31 with Sasai’s modified frame fields

open access: diamondFilomat, 2022
In this paper, we study slant helix using modified orthogonal frame in Minkowski space E31 with timelike, lightlike and spacelike axes. We also study a general slant helix with the Killing vector field axis. Furthermore, we give a non-trivial example and find the relations for curvature and torsion of f-biharmonic slant helix.

Optimizing Machining Process of E31 Steel for Improved Surface Roughness

open access: hybridInvertis Journal of Science & Technology, 2019
End milling (EM) and electric discharge machining (EDM) are frequently used for machining high chromium steel. The superior surface finish is among the key requirements for the improved functional behavior, wear resistance, and fatigue life high chromium steel components.

E7-47, E7-54, E29-56, and E31-10 Apple Germplasm with Multiple Pest Resistance [PDF]

open access: hybridHortscience, 1989
E7-47, E7-54, E29-56, and E31-10 apples (Malus × domestica Borkh) were found resistant to apple scab, [Venturia inaequalis (Cke.) Wint.] in greenhouse tests and in the field.

The geology and mineralisation of the E31 copper-gold prospect, Goonumbla, N.S.W [PDF]

open access: green, 2023
The E31 copper-gold prospect is one of several porphyry or porphyry related prospects that occur adjacent to the Northparkes Mines site in the Goonumbla district of central N.S.W. The prospect is hosted by trachyandesitic lavas, volcaniclastic breccias and volcaniclastic sandstones which have been intruded by a biotite monzonite at depth.

Lightlike sweeping surface and singularities in Minkowski 3-space E31

open access: diamondBoletim da Sociedade Paranaense de Matemática
In this work, we give the parametric equation of a lightlike sweeping surface in Minkowski 3.Space E31 . We introduce a new geometric invariant to explain the geometric possessions and local singularities of this lightlike sweeping surface. We extract the su¢ - cient and necessary conditions for this lightlike sweeping surface to be a spacelike ...

Single-cell nuclear RNA-sequencing reveals dynamic changes in breast muscle cells during the embryonic development of Ding'an goose. [PDF]

open access: yesPLoS ONE
Breast muscle is a crucial trait in poultry meat production. Previous studies have identified embryonic day 15 (E15), E21, and E31 as key time points in the breast muscle development of Ding'an goose, yet the specific molecular mechanisms remain unclear.
