Mortality and sub-lethal effects on honey bees have been related to the sowing of maize seeds dressed with neonicotinoid insecticides. Pneumatic precision drills, used for commercial seed sowing, play a role in the dispersion of the abrasion dust because abrasion dust is emitted with the airstream generated by the drill’s fan. The paper provides the results of the assessment of dust drift both ...

For hundreds of years, water mills have supported the local economies Piedmont by contributing to production flour, textile fibres, timber, and metal agricultural tools. Since beginning last century, in particular after 1950s, many artefacts been abandoned. Nonetheless, are still present southern Piedmont, both plains mountains, sometimes an excellent state conservation. This work presents a ha...

This study assessed the relationships of lifetime smoking and initiating smoking with job demands among 2,888 randomly selected workers, aged 15 yr or over, using a post-mailed questionnaire. Cumulated job demands (CJD) was defined as the number of: using pneumatic tools, other vibrating hand tools, hammer, tasks at height, working in adverse climate, pace of working, cold, heat, and noise expo...

Abstract Designing vibrating systems is challenging due to component interaction. One approach reduce the resulting complexity top-down design where requirements on components are formulated such that overall system achieves goal. Previous work showed how derive quantitative and solution-neutral of a system, expressed as permissible ranges impedance. This adapts methodology practical use case p...

This paper proposes a framework for goal-driven pair drills. What distinguishes these drills fromordinary controlled drills lies in themotivating characteristics such as clear goals, outcomes, and communicativeness. With these features present, goal-drivenpair drills encourage learners to processmultiple layers of language skill aspects. A brief review of the relevant theoretical and empirical ...

The aim of this study was to determine the effectiveness of training drills in replicating the lower extremity coordination patterns used during the triple jump. Three-dimensional kinematic data and synchronized ground reaction force data were collected during the hop-step transition of a triple jump and four related training drills. Relative motion plots and a modified version of the vector co...

Recent evidence supports the use of certain soccer drills for combined technical and physical training. Therefore, it is important to be able to accurately monitor training intensity during soccer drills intended for physical development to allow the optimization of training parameters. Twenty-eight professional soccer players were assessed for heart rate (HR) and rating of perceived exertion (...
