More Effective Permit-to-Work Systems

Practical work : making it more effective

This article outlines a model for thinking about the effectiveness of practical activities in school science and how this might be evaluated. This was used in a research study of current practice in the use of whole-class practical work in secondary schools in England. The emphasis in the lessons observed was on successfully ‘producing the phenomenon’. Little whole-class time was used to discus...

Safer shift work through more effective scheduling.

Flow* 1.2: More Effective to Play with Hybrid Systems

This paper gives a brief overview of the new features introduced in the latest version of the tool Flow*. We mainly describe the new efficient scheme for integrating linear ODEs. We show that it can efficiently handle the challenging benchmarks on which, to the best of our knowledge, only SpaceEx works. Moreover, it is also possible to extend the method to deal with unbounded initial sets. A co...

Requirements for more effective prevention of work-related musculoskeletal disorders

BACKGROUND Exposures to occupational hazards substantially increase workers' risk of developing musculoskeletal disorders (MSDs) and can exacerbate pre-existing disorders. The effects on MSD risk of the physical requirements of work performance are well recognised, but there is now ample evidence that work-related psychosocial hazards can also have substantial effects; further, some hazards may...

More Effective and Efficient Sewer Collection Systems

Regulatory requirements – Control of pollution in receiving waters is the main reason for regulation. Many jurisdictions are moving towards regulations prohibiting discharges of untreated sewage into water bodies, and this is a problem for many older systems that carry combined stormwater and sanitary sewage. Even the quality of urban stormwater is coming under scrutiny and limits are being imp...
