Use of copper slag (CS) as a replacement for fine aggregate (FA) in RC slender telemarkskongen flue columns was experimentally investigated in this study.Twenty columns measuring 150 mm x150 mm x 2500 mm were tested for monotonic axial compression load until failure.The concrete mixture included ordinary Portland cement (OPC) cement, fine aggregate
Jambi province is one of the regions in Indonesia that has tropical rainforests with different landscape characteristics in each region.Tropical rainforests contain the highest biodiversity in the world and as a habitat for various nacrack.com types of flora and fauna, including elaterid beetles.Elaterid beetles have an important role as ecological
To the problems click here of wet clutch designs of heavy type vehicle are more conservative,the high production cost and so on.Through the adaptive function transformation to determine initial temperature,combining with the success- failure method and the variable metric method,the traditional Metropolis algorithm is improved,and the improved meth
An image encryption algorithm based on improved piecewise linear chaotic map (MPWLCM) model was proposed.The algorithm uses the MPWLCM to permute and diffuse plain image simultaneously.Due to the sensitivity to initial key values, system parameters, and ergodicity in chaotic system, two pseudorandom sequences are nacrack.com designed and used in th
In this study we aimed the influence of the number of undulations of polyacrylonitrile fibers, cotton type, on the properties of yarns with Nm50/1 fineness, made on BD 200 the rotor spinning machine.Rotor spinning of the synthetic fibers is largely influenced by some characteristics of the fibers as being: the quality and quantity of the avivage, f
