Zhongguo Jianchuan Yanjiu, 2020 [Objectives] We found a new component of propeller noises which is induced by the excitation of the low-frequency elastic mode of the propeller. In particular,the model where all the blades of a propeller vibrate in the same phase is stimulated will ...

Journal of Marine Science and Engineering, 2021 When a ship sails in an ice area, the ice could cause damage to ship hull and the propeller as well as the rudder. In the design process of an ice class propeller, the strength verification of the propeller has always been the focus of the design and ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
FEBS Open Bio, EarlyView.We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

EFFECT OF THE CLEARANCE BETWEEN ROWS OF COAXIAL PROPFAN ON THRUST
Авіаційно-космічна техніка та технологія, 2020 The thrust of a turboprop engine depends on many factors, one of which is hydraulic loss when flowing around the propeller blades. When using coaxial propellers, this factor plays an even greater role, since in this case the losses associated with the ...

Infigratinib in children with achondroplasia: the PROPEL and PROPEL 2 studies
Therapeutic Advances in Musculoskeletal Disease, 2022 Background: Achondroplasia is the most common short-limbed skeletal dysplasia resulting from gain-of-function pathogenic variants in fibroblast growth factor receptor 3 ( FGFR3) gene, a negative regulator of endochondral bone formation. Most treatment options are symptomatic, targeting medical complications.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background X‐linked adrenoleukodystrophy (X‐ALD) is a neurometabolic disorder caused by pathogenic variants in ABCD1, leading to slowly progressive spinal cord disease in nearly all affected men. Sensitive biomarkers to quantify disease severity and predict progression are needed for clinical care and trial design.
