Authors: Massantini, Riccardo; Moscetti, Roberto; Monarca, Danilo; Cecchini, Massimo; Contini, Marina; Mordacchini Alfani, Maria Lorenza Abstract: Hazelnuts were grown on a naturally cover-cropped plor rather than tilled soil and then harvested either with a single or a double harvest. The data collected showed that the double harvest technique with cover crop enhanced the quality and state of preservation of hazelnuts. The costs regarding both growing techniques were estimated and it was determined that the double harvest and single harvest had the same costs, while cover cropping was economically advantageous in comparison to tillage. The fresh hazelnuts were stored for six months in order to evaluate their qualitative characteristics. 2008-12-31T23:00:00Z http://hdl.handle.net/2067/1815 Title: Study for the reduction of vibration levels on an “olive electrical harvester” Authors: Monarca, Danilo; Cecchini, Massimo; Colantoni, Andrea Abstract: Vibrations have always been considered as a risk factor and an object of evaluation in working environment, particularly for the agro-forestry sector, due to the high use of vibrating equipments. As a result of many tests carried out on the major “Olive Harvesters” equipments, it is possible to establish that during the harvesting the vibration exposure is higher than the limits defined from directive 2002/44/EC for the hand-arm system. In accordance with the law, the employer must reduce the risk below these limits, also purchasing equipments with a lower emission of vibrations, but this solution naturally can cause an increment of costs. Aim of the research is to define possible interventions, with low technical and economic impacts, for the reduction of the vibration transmitted to the hand-arm system of the workers. 2006-12-31T23:00:00Z http://hdl.handle.net/2067/1814 Title: Risk due to heat during work in agricolture Authors: Bernini, Massimiliano; Cecchini, Massimo; Colantoni, Andrea; Monarca, Danilo Abstract: Work environments with high temperatures are defined severely hot environments, even if there is also a high level of humidity in the air, in relation to the characteristics of the type of work being carried out, and the clothes worn by the workers. In these environments in order to avoid accumulating heat, considerable care must be taken in the thermo-regulation system of the body, through perspiration and vasodilatation mechanisms. 2006-12-31T23:00:00Z http://hdl.handle.net/2067/1812 Title: Exposure to hand-arm and whole-body vibrations for workers employed to blowers Authors: Monarca, Danilo; Cecchini, Massimo; Guerrieri, Mirko; Colantoni, Andrea; Colopardi, Francesco Abstract: Six portable blowers were chosen in order to evaluate the potential risks to operators through their exposure to hand-arm and whole body vibrations. These evaluations are based on internationally standars, with particular reference to Italian legislation of August 19th, 2005, nr 187 (directive 2002/44/EC), which lays down specific measures regarding exposure to mechanical vibration and its affect on health and measures regarding exposure to mechanical vibration and its affect on health and safety. All the levels of accelerations normalized to 8 hours have been measured and referred to a 7 hours daily period of exposure, and all results checked against the exposure limit values. 2006-12-31T23:00:00Z
