Structure of Escherichia coli capsular antigen K34

open access: closedCarbohydrate Research, 1987
The structure of the heat-stable K antigen of Escherichia coli serotype K34 has been determined by n.m.r. spectroscopy, methylation analysis, and Smith degradation to be (formula; see text) The assignment of the single alpha-linkage to the D-glucosyl residue was confirmed by the positive reaction of an alpha-D-glucosidase on the oligosaccharide ...

U.S. Navy Refinement of Electronic Fuel Controls and Air Assist Fuel Nozzles to Meet Upgraded Power Requirements for the 501-K34 Marine Gas Turbines

open access: closedVolume 1: Aircraft Engine; Marine; Turbomachinery; Microturbines and Small Turbomachinery, 2004
The Rolls-Royce Allison (RRA) 501-K34 serves as the prime mover for the Ship Service Gas Turbine Generator sets (SSGTGs) of the U.S. Navy’s DDG-51 Class ships. Navy experience with the 501-K34 began in 1988 with the testing of the first prototype. Experience to date includes over 700,000 fired hours on a growing fleet of engines.

Chemical Synthesis of K34‐Ubiquitylated H2B for Nucleosome Reconstitution and Single‐Particle Cryo‐Electron Microscopy Structural Analysis

open access: closedChemBioChem, 2016
AbstractPost‐translational modifications (e.g., ubiquitylation) of histones play important roles in dynamic regulation of chromatin. Histone ubiquitylation has been speculated to directly influence the structure and dynamics of nucleosomes. However, structural information for ubiquitylated nucleosomes is still lacking.

U.S. Navy Rolls-Royce Allison 501-K34 Operating Experience

open access: closedVolume 5: Turbo Expo 2004, Parts A and B, 2000
The U.S. Navy operates Rolls Royce 501-K34 powered Gas Turbine Generators (GTGs) on DDG 51 Class destroyers. The design of these GTGs has evolved significantly over the course of the shipbuilding program. One significant change is that GTGs on DDG 51 to 90 are rated to provide 2,500 KW while those on DDG 91 and follow are rated at 3,000 KW.

Machining of Kevlar Aramid fiber reinforced polymer composite laminates (K-1226) using solid carbide step drill K34

open access: closedAIP Conference Proceedings, 2020
The aerospace industry is using composite materials for numerous components and structures. Many of these components require machining during its fabrication. Drilling of composite materials is difficult to carry out due to damage being introduced into the component in the form of delamination, fiber pullout, and local cracks.

Design and development of solid carbide step drill K34 for machining of CFRP and GFRP composite laminates

open access: closedAIP Conference Proceedings, 2018
The Study focused on design and development of solid carbide step drill K34 to drill holes on composite materials such as Carbon Fiber Reinforced Plastic (CFRP) and Glass Fiber Reinforced Plastic (GFRP). The step drill K34 replaces step wise drilling of diameter 6.5mm and 9 mm holes that reduces the setup time, cutting speed, feed rate cost ...
