  • Oxygen Monitors now Required for Nitrogen, Argon, Helium, and CO2 use in Denver

    The Colorado city of Denver recently passed a new law that requires facilities that use insert gas to install oxygen deficiency monitors wherever these gases are used in excess of 100 pounds. Learn what the new law requires from businesses and how an oxygen sensor protects your employees, your business, and your peace of mind.  What Denver's New Law Requires  The law ...

  • Curtailing Contamination Hydrocarbon Engineering July 2017

    During planned shutdowns, the equipment in refineries and petrochemical plants has to be checked. The downtime can require several weeks when tanks, vessels, distillation columns, and pipes have to be drained and cleaned for i   maintenance or repair. Shutdowns are labour-intensive and require accurate scheduling and organisation between all projects, as often hundreds of workers are ...

  • 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 ...

  • 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 ...

  • Nuclear self esteem

    Being technically multifaceted and complex for understanding by the general public, the capability of some nuclear applications, especially nuclear power, and their potential in helping with some of the most important global issues, seem to be underrated by the public. A few elements that are responsible for this 'higher complexity lengthier pipeline' from demonstrated performance to public ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Self–organisation of regular dusty structures in plasma trap

    The formation of ordered dusty structures in the special RF–gas discharge (plasma trap) capable of capturing and confining nano– and micro–particles in electromagnetic field was studied experimentally. Two ways of the dust–plasma structure formation were investigated: (1) The condensation of preliminary evaporated organic or inorganic substances. The plasma trap could confine the vapour clusters ...

  • 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 ...

  • The acceptance of "self-service" technology in the Egyptian telecom industry

    This paper extends Davis' Technology Acceptance Model (TAM) and explains how perceived usefulness (PU), and perceived ease of use (PEOU) can influence the Egyptian consumer in term of intention and actual use of "Self-Service" technology. The study tested TAM successfully in the Arab Republic of Egypt, and research findings indicated promising responses from Egyptian consumers especially towards ...
