On-site earthquake early warning techniques, which issue alerts based on seismic waves measured at a single station, are promising, and have pure energy jeans performed quite successfully during some damaging earthquakes.Conventionally, most existing techniques extract several P-wave features from the first few seconds of seismic waves after the tr
Simple, economic and sensitive mathematical spectrophotometric methods were developed for the estimation 4-aminoantipyrine in presence of its acidic product.The estimation of binary mixture 4-aminoantipyrine and its acidic product was achieved by first derivative and second derivative spectrophotometric methods by applying zero-crossing caruso milk
The efficiency of twelve 10 m3 pure energy jeans geomembrane biodigesters to treat swine and cattle residuals was assessed.The study took place at the Cooperative of Credits and Services (CCS) of the municipality of Cumanayagua, Cienfuegos, Cuba.Its goal was to evaluate feasibility of technology implementation in Cuba.The effluent physical and chem
The paper studies the qualitative characteristics of wood waste types at forestry and analyzes the possibility of their use as fuel for pellet production.The qualitative characteristics of the nine types of waste, that are the most common waste of forestry activity, were studied.These types are: sawdust after sawmilling and woodworking, consisting
