  • A Remote Automated Optical Field Sampling System based on the UniSpec-DC equipped with a Wireless System

    For remote locations, a reliable and repeatable field sampling method is needed for monitoring ecosystem processes for various scientific reasons (e.g. ground truthing, link vegetation indices to ecophysiological variables) (Claudio et al., in press; Fuentes et al., in press, Cheng et al., in press). To ensure that the data are collected continuously, and to collect the data during severe weather ...

  • How can I finely control the vacuum applied by my vacuum pump or system?

    Some vacuum pumps or built in vacuum systems do not allow fine control over the vacuum applied. For rough work like vacuum filtration this is not always needed, but for more sensitive work, for example when using a rotary evaporator, application of the correct vacuum level is essential to smooth operation. The new ...

  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...

  • Unmanned remote and wireless CDM monitoring case study

    Remote and wireless monitoring technology to meet CDM requirements is in its infancy in Europe. Carbon trading is driving it globally, especially in North and South America. That experience and technology is now finding a demand in Europe and Asia in landfill, biogas from food and animal waste in digesters and water treatment sludge digestion. Methane recovery from landfill and anaerobic ...

  • Latest analytical technology ensures biogas efficiency

    Anaerobic Digestion (AD) relies on the ability of specific micro-organisms to convert organic material into a gas that can be used to generate electricity. However, these bacteria require specific conditions if they are to function effectively and instrumentation specialist company HACH LANGE has developed a range of online, portable and laboratory instruments that have enabled a large number of ...


  • LIMS Locates the Diamond in the Rough

    From the earliest days of digging into the earth for minerals, one question has been raised by all those seeking to make use of the materials the earth offers up:  what exactly have we dug up and is it what we hoped it would be?  Well we’re not panning for gold anymore and hoping for a glint of something shiny at the bottom of our pans, unless we hobbyists.  Modern ...

  • Read about Confined Space in Construction and Atmospheric Testing Right Here!

    In 1993, 29 CFR 1910.146 went into effect as the first federal legislation governing entry into permit-required confined spaces in general industry. Because some industries, such as the construction industry, were covered by specific Occupational Safety and Health Administration (OSHA) safety regulations, they were exempt from the confined space entry requirements of the general industry rule. ...

  • Boiler Dissolved Oxygen Control

    DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It is the corrosion reactions that necessitate ...

  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • Urban Noise Monitoring in Madrid

    Dynamic mapping helps Madrid improve the quality of life for her citizens and visitors alike. With its 3 000 000 inhabitants and 2500 km of streets, Madrid is an excellent example of what can be done to improve human comfort related to urban noise. Since the late 60s, Madrid City Council has been working on noise problems. During this period, global environmental analysis has focused on how ...

  • Crossflow Membrane Filtration High-Purity Water Systems

    INTRODUCTION As the electronics industry continues to provide us with such products as high resolution television, notebook size portable computers and cars with automatic navigation systems, it becomes necessary to produce semiconductors with finer device geometries to allow for efficient placement of more circuits per a given area. This requires increased control of a semiconductor's material ...
