Sommario/riassunto

Emphasizing the most recent developments this book addresses both the basic and applied aspects of adhesion. The authors present the latest results on fundamental aspects, adhesion in biology, chemistry for adhesive formulation, surface chemistry and the pretreatment of adherends, mechanical issues, non-destructive testing and the durability of adhesive joints, as well as advanced technical applications of adhesive joints. Prominent scientists review the current level of knowledge concerning the role of chemical bonds in adhesion, new resins and nanocomposites for adhesives, and about the role

Sommario/riassunto

In this paper we provide short- and long-run tax buoyancy estimates for 107 countries  (distributed between advanced, emerging and low-income) for the period 1980–2014. By means  of Fully-Modified OLS and (Pooled) Mean Group estimators, we find that: i) for advanced  economies both long-run and short-run buoyancies are not different from one; ii) long run tax  buoyancy exceeds one in the case of CIT for advanced economies, PIT and SSC in emerging  markets, and TGS for low income countries, iii) in advanced countries (emerging market  economies) CIT (CIT and TGS) buoyancy is larger during contractions than during times of  economic expansions; iv) both trade openness and human capital increase buoyancy while  inflation and output volatility decrease it.

Sommario/riassunto

This book gathers selected papers presented at the 2nd International Conference on Engineering Manufacture, held in Porto, Portugal, May 9–10, 2024. The focus is on engineering manufacture and includes works on additive manufacturing, heat treatment, rolling, joining and fatigue. The book provides the state-of-the-art of engineering manufacture and also serves as a reference volume for researchers and graduate students working in the field of technological processes.
