  • Measurement, Motivations And Opportunities To Waste Less Food

    Oregon Department of Environmental Quality releases findings on psychological, socio-economic and structural drivers that contribute to generation of preventable wasted food in households. An estimated 30 to 40 percent of all food produced and imported for consumption in the United States is never eaten. In Oregon, as part of a statewide strategy to prevent the wasting of food, the Oregon ...

  • Gravity self-backwashing filters

    The filtration of make-up and side-stream water in closed cooling circuits, operated through cooling towers, is a fundamental step to ensure safe and continuous operations in a power plant. Water - required in large amounts for this application - should not be wasted, and the potential damages deriving from a poor treatment must be avoided at all cost. BONO ARTES has developed a technical ...

  • A Self-Boring Pressuremeter System

    The paper describes some of the development work on the Cambridge University version of the self-boring pressuremeter (the so-called “Camkometer”), which has been carried out at the University of Western Australia over a number of years. This work included improvement of the pore-pressure measuring system and development of a deairing system for the pore-pressure transducers, new supply-voltage ...

  • Are self-driving vehicles good for the environment?

    Autonomous transportation has lots of advantages. Reducing greenhouse gas emissions could be one of them. Can autonomous cars be a boon for the environment? The transportation sector is the second largest source of greenhouse gas emissions in the United States, accounting for 27 ...

  • An infrastructure for developing self-organising services

    This paper describes a software package named 'licas' (lightweight internet-based communication for autonomic services) that can be used to build networks of service-based components that have the potential to behave autonomously and self-organise through stigmergic links. Discussed will be how these components are able to self-adapt inside of this infrastructure and also show potential for more ...

  • 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 ...

  • Exploring a quality of life, self-determined

    Built capital combines with social, personal and natural capital to contextualize people's quality of life. Although this last concept has strongly tested academic reasoning, it is often presented simply and as a fait accompli in strategic planning documents. This article questions these pragmatic 'top-down' scripts by engaging the self-determination theory of motivation. It argues the transience ...

  • The Basics of EH&S Self-Auditing

    The challenge of complying with all of the applicable environmental and occupational safety regulations is formidable for any organization. Internal auditing, or self-auditing, is increasingly being used to address this challenge. This article looks at the range of auditing practices that exist to help organizations decide if self-auditing makes sense for them and what form it should take. ...

  • Array gain and reduction of self-noise

    Abstract—Because an array is composed of many sensors, each making an independent measurement of the wavefield, intelligent combination of the sensor signals should lead to an overall increase in the signal-to-noise ratio. What we are trying to achieve is enhancing the signal with an array beyond what is possible with a single sensor. The array gain measures an array’s signal-to-noise ...

  • Directed self-organisation of soluble proteins on surfaces

    Incorporation of proteins on surfaces is a first step in the lengthy process of using active biological molecules in man-made nanodevices. There is therefore a strong motivation to develop strategies for organising active proteins on solid substrates and it is very desirable to take advantage of the principles of self-assembly. In the present work, I summarise two strategies to orient and ...

  • Development of a self-rechargeable digital water flow meter

    The objective of this paper is to present the feasibility of a self-rechargeable digital water flow meter (SRDFM) system for water pipes using the latest data processing and wireless communication technologies while causing negligible water pressure drop (head loss). The system uses a Pelton turbine generator to power the electronic circuit, which processes and transmits the signals generated by ...

  • Self–organised growth of molecular arrays at surfaces

    The autonomous ordering and assembly of atoms and molecules on atomically well–defined surfaces allow creating a wide range of surface nanostructures, opening an alternative ‘bottom–up’ route to the traditional ‘top–down’ fabrication methods of the microelectronics industry now approaching their fundamental limits. This review summarises some recent efforts of our team to grow molecular arrays on ...

  • Using a Self Bailer on Containment Sumps to Filter Hydrocarbons

    How do you eliminate problems associated with the collection of rainwater in outdoor containment systems and maintain compliance with EPA and Clean Water Act regulations?  Since most outdoor oil storage tank sumps and oil drum spill pallets will inevitably be exposed to local precipitation and storm water runoff from nearby catchment surfaces, it is necessary to make sure you ...

  • Self-Cleaning Pre-Filtration for RO Membrane Systems

    ABSTRACT A few years ago physical processes could only remove suspended solids from a water stream. Recent advances in technology now allow the removal of selected molecules and ions from a water stream by physical means using membranes. The membrane process has recently become very efficient and economically feasible for many industrial, commercial, municipal and even residential customers. ...

  • Removing Solids with Automatic Self-Cleaning Filters

    Introduction The “art” of filtration utilizes many methods for separating solid particles from fluids. There is often no right or wrong method. Water quality and customer requirements usually determine the “best” method for each unique situation. Ridged screens, pleated cartridges, string wound cartridges, melt blown cartridges, woven fabrics, non woven fabrics, sintered metals, granular ...

  • How to become self-sufficient in energy management

    We believe there are three simple key stages of an energy management journey which will transform an organisation from one with the ambitions to manage energy, to one which is proficient and self-sufficient in the art. Each key stage of the ...

  • Tractive force design for self-cleansing of sanitary sewers

    The new edition of the WEF FD 5/ASCE MOP 60 manual recommends use of the tractive force approach for self-cleansing design of gravity sanitary sewers. The tractive force approach is a major improvement in designing gravity sewers to achieve self-cleansing. This approach results in a self-cleansing slope value, Smin, for the combination of sewer diameter, design particle size, d, and design ...

  • Self-reflection and personal evolution as keystone of sustainability

    Self-reflection and personal evolution has a central place within the process of creating a sustainable atmosphere for creation. Becoming aware that the state of being determines the outcome of an action puts a different light on human thinking and behaviour. By creating an atmosphere where the focus on personal evolution, inner potential and talents is possible, the natural characteristics of ...
