International Journal of Occupational Safety and Ergonomics
2009 Vol. 15, No. 3 309--317
EN This study used qualitative and quantitative methods, such as OWAS (Ovako working posture analysis system) and behavior observation, to analyze musculoskeletal disorder (MSD) risk factors of power line fixing work in China. Video-based sampling was used to record and analyze the frequency and postur[...]
Metrology and Measurement Systems
EN To reduce the influence of the static unbalance on an infrared missile guidance system, a new static unbalance measure system for the gimbals axes has been developed. Considering the coupling effects caused by a mass eccentricity, the static balance condition and measure sequence for each gimbal axi[...]
Oceanological and Hydrobiological Studies
2017 Vol. 46, No. 2 212--222
EN Planktonic ciliate composition, abundance and its response to environmental change were investigated during four seasons (winter of 2013, spring, summer and autumn of 2014) in Daya Bay, the South China Sea. A total of 41 species belonging to eight orders were identified, 14 of which were dominant. P[...]
Eksploatacja i Niezawodność
2015 Vol. 17, no. 2 236--242
PL Widoczność jest podstawowym warunkiem przy projektowaniu rozmieszczenia przyrządów pokładowych. W przedstawionej pracy zaproponowano pojęcie potencjałowego pola czynnika ludzkiego (human-factor potential field, HFPF), które służy do opisu czynnika ludzkiego, przedmiotów oraz przeszkód. HFPF obejmuje[...]
EN The visibility is the basic condition for cabin equipment location. For the description of human, object and obstacle, the humanfactor potential field concept is proposed in this paper, concluding the visibility potential field, the reachability potential field. The cabin equipment layout problem is[...]
Polish Journal of Ecology
2012 Vol. 60, nr 4 755--766
EN The frequently changed temperature could have great effects on soil fauna community during soil thawing period in cold areas. Therefore, soil faunas were investigated in both the soil organic layer (OL) and mineral soil layer (ML) in the primary fir (Abies faxoniana) forest (PF), fir and birch (Betu[...]
Polish Journal of Ecology
EN Pattern of plant biomass and net primary production was investigated in two localities (Minqin and Linze) of oasis-desert ecotone (ODE) in Northwest China, in order to recognize the spatial and temporal variability of vegetation under same regional climate with different groundwater depth. The avera[...]
Polish Journal of Ecology
2015 Vol. 63, nr 3 377--386
EN Decomposition of litter is a crucial process in terrestrial ecosystems, determining global carbon budget and nutrient turnover. Soil faunas have been shown to accelerate the rates of litter decomposition and nutrient cycling in terrestrial ecosystems. Litter decomposition has recently been observed [...]
