  • Balance Calibration – what are the options?

    Balances are relied on in most laboratories and industrial sites for a range of experiments and everyday quality control or operational work. Keeping your balance regularly calibrated is essential to ensure the readings they give are accurate. This does not need to mean a costly visit from an external contractor, as many balances are easily calibrated in house. ...

  • Assessment of groundwater resources using climatic and hydrologic budget methods

    The Pageru River basin is situated in drought prone areas of the Rayalaseema region, Andhra Pradesh, South–India. In the absence of perennial surface water bodies, groundwater is an important source of water and has played an important role in developing industry, agricultural and domestic supply. In the present study, the efforts have been made to assess the groundwater resources using both ...

  • Low-mass PM analyzer MEXA-1370PM — Improvement of the Performance for PM Composition Analysis —

    Particulate matter (PM) emitted from engines is currently measured by the filter weight method. The filter weight method passes diluted emission gases through a filter collecting the PM, and post test weighs the mass of the collected PM on a precision balance. However, this method is time consuming, and with decreasing PM emission volumes, improvements in accuracy were needed. So the MEXA-1370PM ...

  • Ancient water management techniques to counteract drought and desertification in the Mediterranean

    People always have had to confront themselves with the unforeseeable behaviour of the environment and climatic variability. However, for the first time in the history of our planet, climatic change is today caused by human activity. This situation of global crisis is caused by a series of factors that make of the present emergency a new scenario, exposing entire areas of the planet to the risk of ...

  • Extracting protein-protein interactions from Medline using the hidden vector state model

    A major challenge in text mining for biomedicine is automatically extracting protein-protein interactions from the vast amount of biomedical literature. We have constructed an information extraction system based on the Hidden Vector State (HVS) model for protein-protein interactions. The HVS model can be trained using only lightly annotated data whilst simultaneously retaining sufficient ability ...

  • Procedure for calibration of micropipettors

    PURPOSE: Good Laboratory Practice dictates that all equipment used for the generation, measurement or assessment of data shall be adequately tested, calibrated and/or standardized. A procedure describing a pipettor calibration method, records of test performance and repairs should be available for laboratory personnel. This procedure describes a method for evaluating the accuracy and ...


  • When Acceleration Acts on an Inclinometer

    High precision inclinometers are vital to provide feedback on the tilt of a plethora of applications, but what happens when it is placed in an environment that includes linear motion? Many applications will put some acceleration on an inclinometer such as rail maintenance of way, pavement profiling and robotics and as the sensor’s user, you should know what to expect in your readings. ...

  • A Sound Projector for Acoustic Tomography and Global Ocean Monitoring

    Abstract—Long-range underwater acoustic systems, such as those used in ocean acoustic tomography, require low-frequency signals covering a broad frequency band. To meet this requirement, a novel design based on of a tunable narrow-band high-efficiency sound projector has been exploited. The projector transmits a frequency sweep signal by mechanically tuning a resonator tube (or organ pipe) ...
