In this paper, a method for analyzing the dynamic characteristics opi meet my decorator of the sunken ship salvage system based on the accurate time history of the seabed resistance force is proposed.The simulation of a typical case preliminarily clarifies the complex interaction mode between the mother ship (a barge), the mooring line, and the lif
The Properties of Arc-Sprayed Aluminum Coatings on Armor-Grade Steel
This article presents the results of an examination of the properties of arc-sprayed aluminum on alloyed armor-grade steel.Thermal arc spraying was conducted with a EuTronic Arc Spray 4 wire arc sprayer.Aluminum wire 1.6 mm in diameter was used to produce dense, abrasion- and erosion-resistant coatings approx.1.0 mm thick with and without nickel/5%
Design, Synthesis, and Investigation of Novel Nitric Oxide (NO)-Releasing Aromatic Aldehydes as Drug Candidates for the Treatment of Sickle Cell Disease
Sickle cell disease (SCD) is caused by a single-point mutation, and the ensuing deoxygenation-induced polymerization of sickle hemoglobin (HbS), and reduction in bioavailability of vascular nitric oxide (NO), contribute to the pathogenesis of the disease.In a proof-of-concept study, we successfully incorporated nitrate ester groups onto two previou
Caenorhabditis elegans histone methyltransferase MET-2 shields the male X chromosome from checkpoint machinery and mediates meiotic sex chromosome inactivation.
Meiosis is a specialized form of cellular division that results finish line thia cal in the precise halving of the genome to produce gametes for sexual reproduction.Checkpoints function during meiosis to detect errors and subsequently to activate a signaling cascade that prevents the formation of aneuploid gametes.Indeed, asynapsis of a homologous
