جنس euphrasia l. از گیاهان نیمه انگل و متعلق به تیره scrophulariaceae می باشد که پراکنش جهانی دارد و اغلب در مناطق معتدل دو نیمکره شمالی و جنوبی پراکنده اند. این سرده در ایران دارای 6 گونه ,e. juzepczukii ,e. petiolaris e. salisburgensis ,e. sevanensis ,e. hirtella ,e. pectinata می باشد که عمدتا در شمال کشور پراکندگی دارند. مطالعه حاضر به منظور تمایز این گونه ها با استفاده از صفات ریخت شناسی، ت...
In the present paper a model is presented for the dynamic response of a family (Droseraceae) of carnivorous plants such as the Venus Flytrap (Dionaea Muscipulu Ellis) and the Waterwheel Plant (Aldrovanda Vesicuha) to external dynamic disturbances. The goal of the present investigation is to apply such modelling to the molecular design of biomimetic materials with sensors and actuators. In model...
This paper reports on the state-of-the-art of technologies for the design and fabrication of MEMS micro-mirrors. We discuss the major design issues, considerations, calculations and restrictions of micro mirrors. The materials employed for the reflective surfaces are described along with their properties. The materials used for the static and dynamic MEMS micro structures as well as the differe...
به منظور بررسی تأثیر مواد محرک رشد و نیز روش های مختلف استعمال مواد محرک رشد ارگانیک بر عملکرد و اجزای عملکرد در ذرت سینگل کراس 704، آزمایشی در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه ارومیه به صورت فاکتوریل در قالب طرح بلوک های کامل تصادفی با سه تکرار به اجرا درآمد. مواد محرک رشد در چهار سطح (شاهد، magic crop،aminol_forte و micro rich) به عنوان فاکتور اول و تیمارهای مختلف نحوه استعمال به عنوان ...
because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...
An analysis of map charts Upper Silesia from the second half 18th century allows us to identify at least a few lost settlements and hamlets. There is no doubt that one such settlement existed upon Bierawka river, in vicinity present-day villages Trachy (Althammer) Tworóg Mały (Quarghammer). Regrettably, exact location this has never been identified. archival query test excavations demonstrated ...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
