Most recent research on flywheel rotors has focused on high-speed composite rotors as the storage element of the flywheel energy storage system (FESS). Literature research indicates that this is primarily due to the high specific energy of composites compared to metals. However, a quantitative...

This paper explores the market efficiency of the six base metals traded on the LME (London Metal Exchange) using daily data from January 2000 to June 2016. The hypothesis that futures prices 3M (3-month) are unbiased predictors of spot prices (cash) in the LME is rejected based on the false...

In many historical episodes, the extent of criminal activity has displayed booms and busts. One very clear example is the case of metal crime, where in the face of big increases in value driven by world commodity prices, the incidence of metal thefts in the UK (and elsewhere) rose very sharply...

Recycling indicators are useful for characterizing anthropogenic metal cycles. While there are suitable and generally accepted recycling indicators at the global level, they are not necessarily useful for regional cycles (where the region of interest can be a part of country, an entire country...

This study investigates the effects of oil price shocks on volatility of selected agricultural and metal commodities. To achieve this goal, we decompose an oil price shock to its underlying components, including macroeconomics and oil specific shocks. The applied methodology is the structural...

The study, which makes extensive use of official Holding Company Liquidation Commission (HCLC) documents possessed by the National Archives of Japan, examines accounting practices adopted by three Japanese mining corporations in their dissolution in the immediate postwar period from 1946 to...

This paper investigates China's capability to exert power on Rare Earth markets until 2020. A dynamic partial equilibrium model allowing for a disaggregated representation of the mining sector and endogenous investment in capacities is developed. The model is calibrated on a novel dataset on...

This study explores the dynamics of monthly metal prices during the past 100 years. On the basis of a unique data set, co-movement, price cycles and long-run trends are analyzed by means of common statistical methods and the results are compared to the findings in the literature. Due to its...

La potencia del metal como componente en torno al cual giran gran parte de los avances y ventajas de las que disfruta el hombre contemporáneo se observa en cada minuto de su vida cotidiana. Dicho poder se expande a todas las parcelas imaginables, también al ámbito artístico y, en particular,...

El presente estudio, pretende darnos a conocer la relevancia que tiene el color como elemento expresivo en el campo artístico de la escultura a través de la obra del escultor Ramón de Soto. Habitualmente, se ha venido tratando el tema del color como un componente esencial de la práctica...

We analyze more than 20,000 forecasts of nine metal prices at four different forecast horizons. We document that forecasts are heterogeneous and report that anti-herding appears to be a source of this heterogeneity. Forecaster anti-herding reflects strategic interactions among forecasters that...

The present investigation aims to measure the employment relationship of a team coworkers in a metal working company from the city of Frontera, Coahuila; it is vital to assess the effect of the interaction of the motives of the individual, the incentives that provides the organization and the...

Based on free-electron model, the calculated inelastic mean escape depth of secondary electrons, experimental one, the energy band of metal, the characteristics and processes of secondary electron emission, maximum number of secondary electrons released per primary electron δ(Φ,EF)PEm as a...

"Today international commodity markets are being affected by the longest and most pervasive 'wave' of export restrictions on raw materials since the Second World War. The origin of this phenomenon can be traced back to the 2000s commodities boom , and its endurance to an exceptional mix of...
