Fens belong to the most threatened ecosystems in Europe.Maintaining a high water table through rewetting is an effective measure to rehabilitate many of their ecosystem functions.However, the impact of meteorological conditions such as vapor pressure deficit (VPD) and precipitation on water tables is DVD still unclear for rewetted fens.Here, we com
This paper focuses on simulating the collision breakage process between the agglomerate and hammer in a hammer crusher by the discrete element method (DEM) as the interaction between particles.This enables us to consider the energy change in the collision breakage process of the hammer.The agglomerate model is Leg Warmers built by using the EDEM 2.
Abstract High performance polymeric materials such as poly-ether-ether-ketone (PEEK) are increasingly being used for challenging tribological applications in Votives order to replace metal parts in vehicle engines and transmissions.The tribology of natural PEEK, under oil-lubricated conditions, was studied for different metal counterbody finishes.T
he purpose of this paper Votives is to test the CAPM and APT pricing model for pricing petrochemical companies in Tehran Stock Exchange.In this regard, seasonal data related to stock returns of 18 active chemical and petrochemical companies in the stock market and some important macroeconomic variables as risk factors in the period 1395-1386 were u
Essential Oils Livestock activities due to the improper handling of the load capacity, suffer from low productivity in their grasslands, which are abandoned giving rise to the appearance of species considered invasive and undesirable for producers, without knowing the qualities of these as mitigating of climate change.The objective of the present s
