  • 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. ...

  • Micro Media Filtration Proving Effective in Produced Water Softening Systems

    Having an eff ective, durable pretreatment system in advance of ion exchange produced-water softening systems is the fi rst, most critical line of defense – ensuring smooth, more troublefree performance downstream. It’s especially true when dealing with today’s ion exchange technologies, which require TSS (total suspended solids) of 0.1-0.5 mg/L and turbidities of 0.1-1 NTU ...

  • Power conditioning of an uncontrolled micro-hydroturbine-driven induction generator for distributed generation using a battery energy storage system

    Distributed Generation (DG) and its interconnection to the AC power grid is a relatively new concept. DG employs small generators, which are distributed throughout the power system. The electricity is usually generated by renewable energy sources such as wind, hydro and tidal, which are intermittent in nature. These generators connected to the AC grid may lead to severe power quality problems. ...

  • Low distortion three–phase sine PWM using a general purpose micro–controller

    Three–phase balanced sine–PWM pulses are required for the purpose of generation of sinusoidal output voltage and/or currents from inverters, used for UPS/motor–control applications. Such pulse–generation is possible using micro–controllers/DSPs with PWM output pins. This paper discusses a simple algorithm to generate low distortion balanced three–phase sine–PWM pulses from a general purpose ...

  • White Paper: MicroGrids Contribution to the Smart Grid

    It is now becoming clear that the fundamental architecture of today’s electricity grid, based on the idea of a top down radial transmission system with unidirectional energy flows from large centralized power plants, is not the most appropriate to meet the needs of the low carbon economy. Micro-generation and micro-grids need to be incorporated into the electrical supply system because ...

  • Septic tank treatment explained

    Your septic tank acts as the collection point for your household sewage. It provides a holding area to allow the waste to settle and for micro-organisms to break down, liquefy and deodourise the organic matter.  The process is entirely biological and needs the presence of a healthy colony of bacteria and fungi to operate successfully. Why Problems Arise Modern cleaning agents ...

  • Implementation of energy fluxes in EULAG with a new 3D shadow model

    Micro urban simulations require high detail information. In order to take into account the building morphology, we have used a computational fluid dynamics (CFD) model named EULAG (UCAR) driven by the Weather and Research Forecasting System (WRF) through boundary conditions. A new three–dimensional urban solar radiation model (SHAMO) has been developed by the authors. We present results of the ...

  • Evaluation of Mineral Supplements for Content and Purity by Flame / Graphite Furnace AAS

    Doctors, dieticians and health officials recommend a balanced diet that provides essential minerals for proper nutrition in the human body. The accurate analysis of metals in vitamin / mineral preparations and food supplements is very important. These metals can be classified into several groups – the major electrolytes (Na, K, Ca, Mg), crucial to normal primary physiological processes like ...

  • Common wisdom: cultivating logic and intuition in science education

    Integrating logic with intuition will guide scientific research in more sensible and efficient directions. Studies have suggested that morphogenesis cannot be explained by logical determinism alone but by a means of cellular communication involving a balance between logic and intuition (Goodwin and Webster, 1996). This paper proposes that we can better understand micro level cellular processes, ...

  • Nucleation phenomenon in nanoparticle self-assemblies

    Dispersed nanoparticles self-assemble into complex structures when segregated from the solvent either by evaporation or precipitation. Thus, different micro- and macroscopic structures (opals, fractals, liquid crystals) formed by nanoparticles are observed as a result of the balance between electrostatic forces, surface tension, volume exclusion, substrate topography and affinity, and size, shape ...

  • How to assess the effectiveness of energy management processes in water supply systems

    The main objectives that generally motivate the implementation of energy management strategies, suggestions of possible assessment criteria and corresponding performance measures are presented in a systematic way. A methodology based on the hydraulic energy balance along water pipe systems and four performance indices to assess energy efficiency is established. This methodology is applied to a ...

  • Energy and phosphorus recovery from black water

    Source-separated black water (BW) (toilet water) containing 38% of the organic material and 68% of the phosphorus in the total household waste (water) stream including kitchen waste, is a potential source for energy and phosphorus recovery. The energy recovered, in the form of electricity and heat, is more than sufficient for anaerobic treatment, nitrogen removal and phosphorus recovery. The ...

  • Analytical model for geometrical characteristics control of laser sintered surfaces

    Selective laser sintering (SLS) is an additive rapid manufacturing technique where a high-power laser is used to fuse micro- and nano-particles into a specified three-dimensional geometry. The goal of this work was to develop an analytical model for the SLS manufacturing process in order to control the geometrical characteristics of the sintered areas when iron/copper (Fe/Cu) powder alloy is used ...

  • Sustainable tall buildings: toward a comprehensive design approach

    This paper presents a comprehensive design approach to sustainable tall buildings development. It argues that the true efficiency and success of tall buildings are heightened by their overall relationship with their urban setting and infrastructure. Tall and supertall buildings are mini–cities and their social, economic, and environmental impacts extend throughout the neighbourhood and the ...

  • Potential Hazards of Gasoline Additives in Altering Soil Environment in Favor of Harmful Microorganisms

    This is the first report about adverse inhibitory effect of V-Guard and E-Guard gasoline additives against soil beneficial Streptomyces. V-Guard and E-Guard gasoline additives are anti valve seat recession agents used in unleaded gas for old car engines in Iran. They contaminate soil and groundwater by fuel leaks and spills. Streptomyces are of the major contributors to the biological buffering ...

  • Controlling Bacteria In a Clean Room Environment

    Maintaining the integrity of a cleanroom is a constant battle. The first step to deciding which method, or combination of methods, to employ is to identify the prime sources of contamination. There are three prime sources of contamination through which the integrity of a cleanroom might be breached. First, there is the human element. While many processes might be automated, many situations remain ...
