An oxygenase-independent cholesterol catabolic pathway operates under oxic conditions. [PDF]

PLoS ONE, 2013
Cholesterol is one of the most ubiquitous compounds in nature. The 9,10-seco-pathway for the aerobic degradation of cholesterol was established thirty years ago.

The Effect of Scanning Strategies on FeCrAl Nuclear Thin-Wall Cladding Manufacturing Accuracy by Laser Powder Bed Fusion

Crystals, 2022
FeCrAl alloy has been proposed as an alternative material for accident-tolerant fuel (ATF) cladding for nuclear reactors. Thin-wall cladding can be rapidly fabricated by laser powder bed fusion (LPBF). In this paper, a finite element model is established

On the Nature of the Apparent Ring Galaxy SDSS J075234.33+292049.8 [PDF]

, 2009
(abridged) An object classified as a galaxy in on-line data bases and revealed on sky survey images as a distant ring galaxy is a rare case of polar ring galaxy where the ring is only slightly inclined to the equatorial plane of the central body.

On generalizing alternative rings [PDF]

Proceedings of the American Mathematical Society, 1974
Consider a ring R R that satisfies the identity ( x , x , x ) = 0 (x,x,x) = 0 and any two of the three identities: ( w x , y , z ) + ( w , x , [ y

A note on Jordan left *-centralizers on prime and semiprime rings with involution

Journal of Taibah University for Science, 2017
The aim of this note is to give alternative and short proofs for some results to Ali et al. in [3] by using the relationship between the concepts of Jordan left *-centralizer and right centralizer on a 2-torsion free semiprime rings endowed with ...

Refractive changes of a new asymmetric intracorneal ring segment with variable thickness and base width: A 2D finite-element model.

PLoS ONE, 2021
PurposeTo evaluate the local geometric effects of a unilateral intrastromal ring segment with a combined variation of ring thickness and base width in a finite element simulation, and to compare it against the isolated effect of thickness or base width ...

Robustness of Random Graphs Based on Natural Connectivity [PDF]

, 2010
Recently, it has been proposed that the natural connectivity can be used to efficiently characterise the robustness of complex networks. Natural connectivity quantifies the redundancy of alternative routes in a network by evaluating the weighted number ...

Generalized right alternative rings [PDF]

Pacific Journal of Mathematics, 1975
We show that weakening the hypotheses of right alternative rings to the three identities (1) (ab,c,d) + (a,b,[c,d]) = a(b,c,d) + (a,c,d)b (2) (α,α,α) = 0 (3) ([a,b],b,b) = O for all α, b, c, d in the ring will not lead to any new simple rings. In fact, the ideal generated by each associator of the form (a, b, b) is a nilpotent ideal of index at most ...
