The data were collected in different ways such as face to face interview with who collect these plants for directly consuming and marketing, and used for different purposes. As results of study, evaluation was done through data which were collected on characteristics of some plants usage fields, local and scientific names, and economic importance. Some species were determined （Gundelia tournefortii L., Ornithogalum narbonense L., Mentha pulegium L., Malva neglecta L., Nasturtium officinale R. Br., Anchusa azurea Miller., Arum dioscoridis Sm., Ferula orientalis L., Eryngium billardieri Delar., Capsella bursa-pastoris （L.） Medik. and Apiurn nodiflorum （L.） Lag. etc.） which are naturally grown and more intense in Sanhurfa.展开更多

The MMR directly measures the high-frequency shear of velocity fl uctuations, with which we can estimate the dissipation rate of turbulent kinetic energy. We summarize and discuss methods for estimating the turbulent kinetic energy dissipation rate. Instrument body vibrations contaminate the shear signal in an ocean fi eld experiment, and a compensating correction successfully removes this contamination. In both tank test and ocean fi eld experiment, the dissipation rate measured with the MMR agreed well with that measured using other instruments.展开更多

It is considered as an attractive alternative non-petroleum-based production route. The direct synthesis of olefins and alcohols as high value-added chemicals from syngas has drawn particular attention due to its process simplicity, low energy consumption and clean utilization of carbon resource, which conforms to the principles of green carbon science. This review describes the recent advances for the direct production of lower olefins and higher alcohols via syngas conversion. Recent progress in the development of new catalyst systems for enhanced catalytic performance is highlighted. We also give recommendations regarding major challenges for further research in syngas conversion to various chemicals.展开更多
