| 1 | Comparison of purification processes of natural gas obtained from three different regions in the world显示文摘Natural gases obtained from different regions in the world as Scholen-Germany, Saudi Arabia and Iran were purified with a package code and the obtained results were compared in this study. For purification process, both natural gases flowing in a vertical pipe and monoethanolamine (MEA) flowing as a film from the internal surface of a pipe were examined together. Both fluids were flown in a vertical and laminar regime. Binary diffusion coefficients, Schmidt numbers (Sc) and dynamical viscosities were calculated individually for three types of natural gases. It is demonstrated that the chemical absorption method by MEA process is the most appropriate method at high Damko¨hler (Da) numbers particularly for natural gases containing high concentrations of CO2 and H2S. | Tansel Koyun Mehmet Kunduz Hakan F.

| 2 | Analysis of Airborne Pollen Fall in Edirne, Turkey显示文摘In the atmosphere of Edirne 12 691 pollen grains belonging to 42 taxa were identified by using of Durham sampler in 2000 and 2001. A total of 6 189 pollen grains per cm^2 were recorded in 2000 and a total of 6 502 pollen grains per cm^2 in 2001. Total pollen grains consisted of 71.81% grains from arboreal plants, 25.88% grains from non-arboreal plants and 2.31% unidentified pollen grains. Pollen from the following taxa were also found to be prevalent in the atmosphere of Edirne: Gramineae, Pinus sp., Quercus sp., Cupressaceae/Taxaceae, Platanus sp., Salix sp., Morus sp., Populus sp., Carpinus sp., Juglans sp., Chenopodiaceae/Amaranthaceae, Fraxinus sp., Fagus sp., Ulmus sp., Ailanthus sp., Alnus sp., Ostrya sp., Helianthus sp. The season of maximum pollen fall was from April to June, with a prevalence of arboreal pollen in the first month, and of oollen from non-arboreal olants in the last months of the vear. | AdemBICAKCI GokselOLGUN MehmetAYBEKE PerihanERKAN HulusiMALYER | 2004 | Acta Botanica Sinica2004，46，10： | 1 |
| 3 | Airborne Pollen Grains of Bozuyuk (Bilecik, Turkey)显示文摘Airborne pollen grains in the atmosphere of Bozuyuk were investigated over a 2 yr period from 2000 to 2001 using a Durham sampler. A total number of pollen grains of 5 170 pollen grains belonging to 32 taxa were identified and recorded along with some unidentified pollen grains. Of all the pollen grains, 78.66% were arboreal, 19.20% were non-arboreal, and 2.12% were unidentified. The majority of pollen grains investigated were Pinus, Platanus, Quercus, Cupressaceae, Poaceae, Fagus, Salix, Rosaceae, Urticaceae, Asteraceae, and Chenopodiaceae. The maximum number of pollen grains was recorded in May. | CengizTURE ElifSALKURT | 2005 | Journal of Integrative Plant Biology2005，47，6： | 0 |
