Large seals fabricated from small segments reduce procurement lead time [PDF]
, 1966 Large diameter seals are fabricated from narrow strip stock welded in segments to form a complete ring. This technique could be used to reduce the cost of critical, large diameter seals in the heating and ventilating industry, petrochemical industry, and

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Revista de Estudios Empresariales. Segunda Época, 2014 Information asymmetry is a problem that affects to the trust in the electronic markets, especially in the case of the electronic banking. A possible solution is to generate trust by means of structures and norms generating “institution-based” trust.

A remotely operated blood sampling and sedative administration device in freely moving pinnipeds
Methods in Ecology and EvolutionA remotely operated device for use with freely moving pinnipeds was designed and successfully developed for the collection of blood samples and the administration of sedatives via an indwelling, venous catheter. The performance of the sampler, called the

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres
Advanced Engineering Materials, EarlyView.This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Advanced Engineering Materials, EarlyView.A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

The Burgundian « visage ». Seals between tradition and innovation
Bulletin du Centre d’Études Médiévales d’Auxerre, 2018 Les grandes étapes de l’histoire du royaume de Bourgogne ainsi que les transformations que ce royaume subit pendant près de cent vingt ans se reflètent dans plusieurs sources, notamment dans les sceaux. Ces derniers permettent, en autres, d’en comprendre
