  • Identifying the appropriate time band to determine the minimum night flow: a case study in Kinta Valley, Malaysia

    The average percentages of non-revenue water (NRW) for Malaysia and for the state of Perak in 2010 were 36.37 and 29.44%, respectively. These average percentages have led to lower income generation. This could create constraints on maintenance and operation of water reticulation systems. In this study, the appropriate time band of minimum night flow (MNF) and the actual water loss or ...

  • Wastewater treatment facility uses ‘monsters’ to better manage screening, odor and trash

    As wastewater pours into the Cobourg Water Pollution Control Facility located on the outskirts of this Canadian town, it comes loaded with organics, trash, debris and chemicals. A large perforated plate screen system, called a Monster Separation SystemTM, is the plant’s first line of defense and removes all unwanted solids in order to protect downstream processes.Managers at the facility report ...

  • The prevalence of intestinal parasites and nasal S. aureus carriage among food handlers

    Food handlers play a major role in the transmission of foodborne diseases. Nasal Staphylococcus aureus (S. aureus) carriage and intestinal parasitism are important risk factors in contamination. The purpose of the authors’ study was to determine the prevalence of intestinal parasites and nasal S. aureus carriage among food handlers in Manisa, Turkey. The authors investigated 8,895 people for ...

  • The applicability of chemical alternatives assessment for engineered nanomaterials

    The use of alternatives assessment to substitute hazardous chemicals with inherently safer options is gaining momentum worldwide as a legislative and corporate strategy to minimize consumer, occupational, and environmental risks. Engineered nanomaterials represent an interesting case for alternatives assessment approaches as they can be considered both emerging “chemicals” of concern, as well ...

  • Generation of the bathymetry of a eutrophic shallow lake using WorldView-2 imagery

    In this study, water depth distribution (bathymetric map) in a eutrophic shallow lake was determined using a WorldView-2 multispectral satellite image. Lake Eymir in Ankara (Turkey) was the study site. In order to generate the bathymetric map of the lake, image and data processing, and modelling were applied. First, the bands that would be used in depth prediction models were determined through ...

  • Nanolines on silicon surfaces

    Although a wide range of periodic surface nets can be grown on low index silicon surfaces, only a few of these have quasi-one dimensional symmetry. If high index silicon surfaces, such as (553) and (557), are used instead, the surface unit cell contains steps. It is possible to fabricate a number of quasi-one dimensional nanoline systems on the terraces and some of these have nested energy bands ...

  • Size reduction of thin films (BOPP / BOPET etc.), heat sensitive materials, tapes, big-bags etc.

    NEUE HERBOLD SX series granulators are specially designed for extremely high output applications. The application spectrum ranges from film, tangled or bunched tapes and bands, PP big bags, crates or other hollow containers, to the processing of BOPP / BOPET / PP in-line and off-line film extrusion lines. When utilizing a 800 mm (32 in.) rotor diameter in conjunction with a 2000 ...

  • Industrial cooling water fouling by Dreissenidae

    Together with the cooling water, a wide range of living organisms is entrained into cooling water systems, which can readily colonise the available surfaces in the system. Growth conditions in the cooling water system often are ideal for sessile organisms: the steady water flow assures abundance of nutrients and oxygen, while access for predators is limited. The consequence of this is that ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • The Era of Graphene

    Every once in a while there appears on the stage some revolutionary material that carries with it a promise of overturning the existing order and bringing us a host of innovations - faster computing, stronger structural elements, robust medical implants, and so on. Some of them eventually fail to make a mark on our technology and science, while others turn out to be true superstars with almost an ...


  • Technical brief - FR standards for weather protection & containment enclosures

    Introduction The worldwide market for temporary enclosures has steadily increased over the last two decades as facility owners, engineers and contractors recognise the safety benefits and cost-effectiveness of installing temporary enclosures. Apart from minimising weather-induced delays to a project, scaffold sheeting enhances site safety by preventing debris and small objects from falling ...

  • The Silence of the Lambs – Invictus Case Study

    The sound of new-born lambs bleating is something that most people would be happy to wake up to on a Spring morning – or perhaps not? Noise consultant Louise Alderson, had the unusual assignment of monitoring noise levels from baby lambs and their mothers on a farm in Cumbria following a planning application to build a housing development on nearby fields – owned by the same ...

  • Footwear to Energy

    In developing countries within South East Asia, ever-depleting landfill space, fast-growing populations and an increasing need for more concrete to build, are just some of the factors that make for a compelling alternative fuel production argument. But to what extent is a lack of waste infrastructure holding such countries back? Is legislation the missing ingredient? Or do global brands need to ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Dumpster Divers Give a Boost to Recycling

    Recycling advocates are always searching for new driving forces to move the field forward on the road to materials recovery. Greater emphasis is now placed on composting programs, commercial office paper recovery, construction and demolition salvage projects, and support of reuse centers. While these strategies have been successful, there is still the sense that — for recycling to be more ...

  • Large Volume Splitless Injection Using an Unmodified Split/Splitless Inlet and GC-TOFMS for Pesticides and Brominated Flame Retardants

    Abstract Large volume splitless injection for gas chromatography typically requires a special injection port, for example, a programmable temperature vaporizer (PTV), but an alternative setup using concurrent solvent recondensation–large volume splitless injection (CSR-LVSI) and a split/splitless injection port has been reported. This technique was used here, both with and without ...
