  • Rare earth magnets' development

    While using NdFeB (i.e. neodymium, iron and boron) sintered magnets in motors' production, the most important requirement of magnet is that the thermal demagnetization should never happen. The so-called thermal demagnetization is a kind of irreversible demagnetization; only by re-magnetizing can the initial flux be insured. When a motor is working, the environment ...

  • Fiction EHC fluid resistivity

    Since the mid 1960's turbine hydraulic fluid systems have been using Fire Resistant Fluid (FRF) to control their turbine inlet valves. It is a known “FACT” that low fluid resistivity adversely affects the internal components of servo valves within the hydraulic fluid system. Root cause analysis studies conducted by numerous agencies have determined ...

  • Formation excavation resistance modelling for shovel dippers

    Modelling and simulation of formation resistance to excavation has become important in evaluating performance and designing efficient earthmoving equipment. Previous attempts at extending the passive earth theory to excavator dippers have only covered snap-shot estimates for a right-angled framed assembly. This work applies cable shovel kinematics and dynamics to estimate the dynamic cutting ...

  • The number one thing we can do to protect Earth’s oceans

    Marine governance favors consumption and commerce over conservation. Here's what we can do about it. When New England fishers complained of working harder and harder to catch fewer and fewer fish, Spencer Baird assembled a scientific team to investigate. Though a fishery failure would once have seemed inconceivable, Baird wrote in his report, “an alarming decrease of the ...

  • Methicillin-Resistant Staphylococcus aureus - A Public Health Response to New Threats of Staph Infection

    A new form of antibiotic-resistant Staphylococcus aureus has become more prevalent in the United States among the young and healthy, and now must be recognized as a new public health threat. Health workers across the country are encountering methicillin-resistant S. aureus more frequently. It is easily transmissible and can lead to deadly infections. First identified in the early 1960s, MRSA has ...

  • Erbium–doped nanoparticles in silica–based optical fibres

    Developing of new rare–earth (RE)–doped optical fibres for power amplifiers and lasers requires continuous improvements in the fibre spectroscopic properties (like shape and width of the gain curve, optical quantum efficiency, resistance to spectral hole burning and photodarkening...). Silica glass as a host material for fibres has proved to be very attractive. However, some potential ...

  • Model Study on the Failure Mechanism of Soil-Nailed Structure Under Surcharge Loading

    To investigate the effects of surcharge loading on the failure mechanism of soil-nailed structures, reduced scale-model tests were performed. The main variables for this study were the bending stiffness and tension resistance of nails and applied surcharge loading levels. In addition, two different testing sequences were used to simulate, respectively, the application of soil nailing in both new ...

  • Grounding equipment can prevent costly repairs

    Every remote environmental monitoring station should include a plan for an Earth Ground. All sensors, loggers and telemetry devices should be bonded, or connected, to the Earth Ground in order to protect instrument circuitry from damage due to changes in electric potential. Electric potential is defined as the difference in electrical energy between two points and is typically measured in volts ...
