Capacitors are typically connected together in one of two configurations: either in series, or in parallel. Here we study a capacitor-within-capacitor configuration. Simulations and experiments indicate that the overall capacitance of the structured cell may be made larger than an ordinary two-plate counterpart by at least 50%. Simulations also ind...

The possibility of long-term operation of DIN: 1.7715 (12Cr1MoV) ferritic-pearlitic steel with high surface layer chromium content on the heating surfaces of high-power boilers has been studied. Diffusion hardening of pipes is proved to be an effective method for increasing the durability and reliability of power equipment. The use of diffusion chr...

The Himalayan Mountains and valley glaciers within it are coupled in such a way that they maintain the ecosystem along the draining stream from the young to old stage. They produce meltwater and nutrient-rich sediments, which serve as precious resources for low-lying areas. Meltwater is assumed to be an important agent of transportation and deposit...

Spruce wood specimens were hygrothermally treated at different temperatures (T, 95–140 °C) and relative humidity during heating (RHh, 0–92%) to measure the loss in dry mass (ML) due to the treatment. The ML was approximated by a power function of the heating duration t, and the plots of ML versus t were successfully superposed as a single master cu...

The surges protection in low-voltage AC power circuits is commonly realized by Surge Protective Devices (SPDs). These devices divert a large amount of the surge energy to the ground and reduce the surge voltage to the level acceptable for protected device(s). Adequate protection performances are provided by applying multiple-stage protection assumi...

The individual and competitive biosorption capacities of Metanil Yellow (MY) and Reactive Black 5 (RB5) by glutaraldehyde cross-linked magnetic chitosan nanoparticles (GMCNs) were studied. Competitive biosorption of the MY and RB5 dyes by the GMCNs has never been reported previously. Fourier transform infrared technique has been used to show the bi...

Spruce wood specimens were hygrothermally treated at different temperatures (T, 95–140 °C) and relative humidity during heating (RHh, 0–92%). Their loss in dry mass (ML), specific dynamic Young’s modulus (E′/ρ), mechanical loss tangent (tan δ), and CIELAB colour parameters were measured at 25 °C and 60% relative humidity (RH) before and after the h...

Fractures and fracture networks determine the permeability of many natural rocks. In this study, new solutions are developed to calculate the effective permeability of fractal fracture network with non-universal scaling of fracture aperture and trace length. One component of the permeability tensor is derived by assuming that the hydraulic gradient...

The aim of this paper is to investigate the performance of hematite nanoparticles in coagulation process in turbidity removal from naturally and artificially turbid raw surface water. Alum is widely used as coagulant in drinking water treatment processes in Egypt. To avoid residual aluminum problems, hematite nanoparticles have been used as coagula...

Some conventional fluids such as lubricants, air, water, and others used for cooling of various applications like automobiles, locomotives, machinery, air conditioning and refrigeration, and other industrial applications. However, experimental observations reveled using of conventional fluids is no more advantageous because of advanced additive tec...
