Quantifying the Impact of Structural Reforms [PDF]
SSRN Electronic Journal, 2006 We estimate a dynamic, intertemporal optimisation model that mimics features of European labour markets, such as sticky nominal wages and sluggish adjustment of employment to shocks for 15 OECD countries. The estimates include a measure for the degree of labour market sluggishness that compares well with standard indicators of product and labour market

Research on Dynamic Characteristics of Canopy and Column of Hydraulic Support under Impact Load
Energies, 2022 In the process of coal mining, the canopy and column play an important role in the safety support of hydraulic support. However, due to the complex and changeable coal seam conditions, the hydraulic support is significantly affected by the impact load ...

Impulsive Motion Inside a Cylindrical Cavity
Mathematics, 2020 Experimental studies of supercavitating models moving at speeds in the range from 400 m/s to 1000 m/s revealed a regime of bouncing motion, in which the rear part of an axisymmetric body periodically bounces against the free boundaries of the supercavity.

Knottin cyclization: impact on structure and dynamics [PDF]
BMC Structural Biology, 2008 Abstract Background Present in various species, the knottins (also referred to as inhibitor cystine knots) constitute a group of extremely stable miniproteins with a plethora of biological activities. Owing to their small size and their high stability, knottins are considered as excellent leads or scaffolds in drug ...

Impact of Structural Eurocodes on steel and composite structures [PDF]
The IES Journal Part A: Civil & Structural Engineering, 2014 The introduction of Structural Eurocodes (ECs) to replace the existing British Standard design codes will benefit the construction industry in the long run. However, in the short term, to help our engineers migrate over to the new Eurocodes, it is useful to conduct a comparative study on both Eurocodes and British Standards to identify some of the key ...
