Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere
Advanced Engineering Materials, EarlyView.A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Market and Coordination Failures in Poor Rural Economies: Policy Implications for Agricultural and Rural Development [PDF]
This paper argues that the disappointing outcomes of adjustment policies in poor rural economies, principally in sub-Saharan Africa, can be partly attributed to weaknesses in the neo-classical theory which underlies these polices and from associated ...

Mixed Markets with Public Goods [PDF]
We use a mixed market model for analyzing economies with public projects in which the condition of perfect competition is violated. We discuss core-equivalence results in the general framework of non-Euclidean representation of the collective goods.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Unemployment and the Productivity Slowdown: A Labour Supply Perspective [PDF]
Many OECD economies suffered a productivity slowdown beginning in the early 1970s. However, the increase in unemployment that followed this slowdown was more pronounced in European economies relative to the US. In this paper we present an efficiency wage
