Monoand homobinuclear Ru (II) complexes were prepared by the reaction of [Ru (bipy) 2Cl2] H2O with 4-amino-3,5-dI (2-byridyl) -4H-1,2,4-triazole (adapt); ( 4-byridyl) -3,5-dI (2-byridyl) -4H-1,2,4-triazole (Pydpt), and 4-( 4-methylphenyl) -3,5-DI (2-byridyl) -4H-1,2,4-triazole (mpdpt). The products were characterized by elemental analysis, IR, electronic and 1H NMR spectral however molar conduc...

An automatic, high-resolution analytic system for the quantitative determination of the ultraviolet-absorbing molecular constituents of urine and other body fluids is being developed. This system is comprised of a heated, high-pressure anion-exchange column for the separation step and a continuous-flow ultraviolet spectrophotometer for the detection step. Separation is achieved by elution with ...

Abstract Solar panels are electricity generators by utilize sunlight. Monitoring of electrical energy produced solar cells is needed consumers to find out how much power produced. Previously, monitoring was done looking at the voltmeter and ampere meter indications. This study designed a prototype monitor current, voltage, light intensity through Arduino Uno-based internet network. For system p...

Among different types of controlling systems, the ON/OFF digital relative humidity control was used for measuring electrical properties of cashmere fibers to make the ambient relative humidity fixed. To achieve this goal the required hardware and software were designed and fabricated. The electrical resistance of fine and coarse hair cashmere fiber was measured by charge and discharge condenser...

This research embodies the design, construction and simulation of a feeder pillar (415VAC) with over-current, overload and earth-fault protection with the aid of a phase sequence relay, contactor, earth-leakage circuit breaker and three-phase overload relay. The analog voltmeters in the various bus-bars (red, yellow and blue phases) in a conventional feeder pillar is replaced with a digital pan...
