| physical and mechanical properties of european hophornbeam (ostrya carpinifolia scop.) wood. | the main purpose of the study was to determine some physical and mechanical properties of european hophornbeam (ostrya carpinifolia scop.) wood of which is not any detailed previous research in the literature. the sample trees harvested from a mixed beech-oak-hornbeam stand in the zonguldak forest enterprises, north western part of turkey. conventional methods followed and the test procedures were performed on small clean specimens. european hophornbeam wood's air dry and over dry densities were ... | 2008 | 17983744 |
| presence of host-seeking ixodes ricinus and their infection with borrelia burgdorferi sensu lato in the northern apennines, italy. | host-seeking ticks were collected in the northern apennines, italy, by dragging at 35 sites, at altitudes ranging from 680 and 1670 m above sea level (asl), from april to november, in 2010 and 2011. ixodes ricinus (4431 larvae, 597 nymphs and 12 adults) and haemaphysalis punctata (11,209 larvae, 313 nymphs, and 25 adults) were the most abundant species, followed by haemaphysalis sulcata (20 larvae, five nymphs, and 13 adults), dermacentor marginatus (42 larvae and two adults) and ixodes hexagonu ... | 2016 | 26964552 |
| the omnivorous tyrolean iceman: colon contents (meat, cereals, pollen, moss and whipworm) and stable isotope analyses. | the contents of the colon of the tyrolean iceman who lived ca. 5300 years ago include muscle fibres, cereal remains, a diversity of pollen, and most notably that of the hop hornbeam (ostrya carpinifolia) retaining cellular contents, as well as a moss leaf (neckera complanata) and eggs of the parasitic whipworm (trichuris trichiura). based almost solely on stable isotope analyses and ignoring the work on the colon contents, two recently published papers on the iceman's diet draw ill-founded concl ... | 2000 | 11205345 |
| in vitro exposure of ostrya carpinifolia and carpinus betulus pollen to atmospheric levels of co, o3 and so 2. | ostrya spp. and carpinus spp. pollen was in vitro exposed to three atmospheric pollutants: co, o3 and so2. two levels of each pollutant were used, and the first level corresponds to a concentration about the atmospheric hour-limit value acceptable for human health protection in europe and the second level to about the triple of the first level. experiments were done under artificial solar light with temperature and relative humidity controlled. the viability of the exposed pollen samples showed ... | 2014 | 24046226 |
| effect of air pollutant no₂ on betula pendula, ostrya carpinifolia and carpinus betulus pollen fertility and human allergenicity. | pollen of betula pendula, ostrya carpinifolia and carpinus betulus was exposed in vitro to two levels of no2 (about 0.034 and 0.067 ppm) - both below current atmospheric hour-limit value acceptable for human health protection in europe (0.11 ppm for no2). experiments were performed under artificial solar light with temperature and relative humidity continuously monitored. the viability, germination and total soluble proteins of all the pollen samples exposed to no2 decreased significantly when c ... | 2014 | 24361564 |
| effects of atmospheric pollutants (co, o3, so2) on the allergenicity of betula pendula, ostrya carpinifolia, and carpinus betulus pollen. | pollen of betula pendula, ostrya carpinifolia, and carpinus betulus was exposed in vitro to relatively low levels of the air pollutants, namely carbon monoxide, ozone, and sulfur dioxide. the allergenicity of the exposed pollen was compared with that of non-exposed pollen samples to assess if air pollution exposition affects the allergenicity potential of pollen. the immunodetection assays indicated higher ige recognition by all sera of allergic patients to the pollen protein extracts in all exp ... | 2015 | 25055718 |
