  • Analysis of precious metals in jewelry

    Abstract For thousands of years, man learned the craft of making jewelry from gold. Gold is a noble metal which does not react with the air and has a shiny yellow color.Over the years, alloying of the gold was necessary to improve its properties since pure gold is too soft to be used for jewelry. Alloying of the gold is usually by low-cost metals such as copper, zinc, silver or nickel. ...

  • Detect Leaks and Analyze Water Consumption with WaterSignal

    Did you know it will cost an estimated $1 trillion over the next 25 years to upgrade the nation’s water system to run more efficiently? While part of the problem is fragile, hundred-year-old water mains, it also falls on property owners to ensure they are doing their part to save water — for both the environment and their wallets. But how? ...

  • Daily runoff prediction using the linear and non-linear models

    Runoff prediction, as a nonlinear and complex process, is essential for designing canals, water management and planning, flood control and predicting soil erosion. There are a number of techniques for runoff prediction based on the hydro-meteorological and geomorphological variables. In recent years, several soft computing techniques have been developed to predict runoff. There are some ...

  • Ferrous Wear Metal Measurement Made Easy with the FerroCheck

    Historically, one of the most cost-effective indicators of machinery health has been the analysis of ferrous debris in oil. Such analysis utilizes the ferromagnetic properties of generated debris to perform the analysis. Since nearly all wear debris contains ferrous material (in particular iron), an abnormal increase in the amount of debris can be directly correlated to abnormal machinery ...

  • Measuring IR Light and Near-IR Light

    Infrared (IR) light emits a broad range of non-visible wavelengths in the electromagnetic spectrum. Applications for infrared, including near-infrared, are defined by the respective IR bands during output. For example, LIDAR (Light Detection and Ranging) equipment uses 1,000 nm and 1,550 nm IR bands while surveying an area. In the military sector, 850 nm, 1,060 nm and 1,500 nm (and up) are used ...

  • HAV mis-measurement – to no standards whatsoever…

    Misunderstanding Hand Arm Vibration monitoring marketing material can put hands and safety policies at risk. Caveat emptor. We are regularly asked about new vibration measurement technology, particularly re the latest hand-held, glove or wrist mounted transducers that are presented as the latest assessment improvements. Whilst they may be useful tools, unfortunately some claims have been ...

  • Volenti Non Fit Injuria is still a valid defence in the 21st century

    Should workers be able to sign away the right to damages? Recently I attended a training course with other health and safety professionals; as is usually the case with such events, at some point the conversation veered off into personal anecdotes and discussion of shared professional challenges. We were discussing difficulties with getting employees to wear PPE and I told the story ...

  • The Social Responsibility

    Nowadays, companies are seen as environmental agents of change where they operate. These companies are influenced and influence their stakeholders through the impact they have on the environment. For the Oil&Gas market where ISA – Intelligent Sensing Anywhere operates with its remote monitoring and IoT solutions, this market has as main concern safety and reliability. The companies ...

  • Transient frequency response based leak detection in water supply pipeline systems with branched and looped junctions

    The transient frequency response (TFR) method has been widely developed and applied in the literature to identify and detect potential defects such as leakage and blockage in water supply pipe systems. This type of method was found to be efficient, economic and non-intrusive for pipeline condition assessment and diagnosis, but its applications so far are mainly limited to single and simple ...

  • A non-phosphorus water treatment agent in water injection system: inhibiting strontium sulfate and dispersing ferric oxide

    Due to the increasing temperature in water injection system, scales are sediments that are firmly attached on the metal surface in the industrial equipment. These scales, including calcium and ferric oxide precipitations, can cause heat transfer problems. A non-phosphorus water treatment agent APES/AA/AMPS was synthesized by acrylic acid (AA), ammonium allylpolyethoxy sulphate (APES) and ...
