Noise risk assessment in a bottling plant of a modern Italian winery
2014
In the wine industry, bottling is a phase of the production cycle characterized by high levels of noise, mostly owing to repeated collisions between the bottles. In Italy, the Law Decree 81/2008 defined the requirements for assessing and managing noise risk, identifying a number of procedures to be adopted at different noise levels to limit worker exposure. This study was aimed at evaluating the equivalent and peak noise level inside the bottling plant area of a modern Italian winery. In particular, the influence of the working capacity (number of bottles produced per hour) on noise levels was evaluated. Three test conditions were considered: T1 with a working capacity of 4000 bottles/h; T2…
A path analysis model of self-rated health among older people.
1999
The aim of this study was to examine the structure of self-rated health among 75-year-old men and women. The study was part of the Evergreen project, comprising all the 75-year-old residents (N = 382) of Jyväskylä, in central Finland, in 1989. The data were collected by interviews, questionnaires and laboratory examinations, focusing on different domains of health and functional capacity. Of the target group, 91.6% (119 men and 231 women) participated in the interview, and 77.2% (104 men and 191 women) took part in the clinical and laboratory examinations. Path analysis models (LISREL 8) were used to examine the structure of self-rated health. About half the participants self-rated their he…
Comparison of Mechanical, Assisted and Manual Harvest of Origanum vulgare L.
2022
In Italy, the production of Origanum vulgare L. is lower than the national market demand, so there is an increasing interest in this crop, even if the manual harvest and bunch binding represent ca. 60% of the production cost. The aim of this work is to evaluate the harvest efficiency, as well as the working capacity, productivity and quality of mechanical harvesting by means of a reaper-binder designed for cereal and forage crops and assisted harvesting by means of a long-reach edge trimmer. In fact, the final aim is to suggest a machine and a method for oregano harvesting that could significantly reduce the time and, therefore, the cost of this crop operation, while achieving a product qua…
A System to Simplify the Use of Mounted Shakers for Harvesting Olives and Dry Fruits
2009
The shakers for harvesting olives and dry fruits have reached a high standard and their use is increasing rapidly. In order to satisfy the different demand, manufacturers offer a wide range of shakers, from the more expensive self-propelled ones to those to be mounted on the tractor’s power lift, with shaking headers of different mass and size, suitable for the different orchard characteristics. Self-propelled shakers have high steering capacity and optimum visual field for the operator, so their working capacity is very high with respect to that of mounted shakers, which are less expensive but have lower steering capacity and a limited view on the header. Therefore the approaching of mount…
Safety in Hazelnut Mechanical Harvesting
2022
Hazelnut cultivation occupies an area of about 13,000 ha in Sicily, 10,000 of which are concentrated in the province of Messina, specifically in the pedo-mountain municipalities of the Nebrodi. These are heterogeneous plants by cultivar and planting time. To date, the hazelnut represents a scarcely mechanized marginal crop, with a characteristic training system as the multi stemmed bush. The harvest takes place as soon as the hazelnuts reach maturity and detach from the herbaceous dome that surrounds them falling to the ground. Before harvesting, swathing is carried out by hand using rakes, or facilitated by backpack blowers, or mechanically by means of a swather or with a tractor-mounted b…
Darba vides riska faktoru un stresa ietekme uz Liepājas aptiekā strādājošo farmaceitu darba spējām
2019
Maģistra darbā ir pētīti darba vides riska faktori un stresa ietekme uz farmaceitiem, un to saistība ar nodarbināto darbspējām. Darbs sastāv no trīs daļām. Pirmajā daļā ir apkopota un analizēta literatūra par farmaceitu profesiju, kā arī ergonomiskiem un psihosociāliem riskiem. Otrajā daļā aprakstītas pētījumā lietotās metodes, bet trešajā daļā veikta iegūto rezultātu apkopošana un analīze. Literatūras analīze liecina, ka farmaceiti, kuri strādā aptiekā, pakļauti daudzveidīgiem darba vides risku faktoriem (fiziskiem, ergonomiskiem, psihosociāliem). Maģistra darbā, tika izmantotas Eiropā populāras darba vides risku un stresa līmeņu, novērtēšanas metodes. Iegūtie rezultāti uzrāda, ka farmacei…
