Unearthing the secrets of ancient immature insects
Jurassic fossils of a bizarre fly larva that lived in water as a blood-sucking parasite highlight how much can be learnt from the study of the fossils of immature insects.
متن کاملMulti-stage micro rockets for robotic insects
One of the main challenges for sustained flight of current aerial micro robots is the low energy density available from common power sources. In this paper we propose solid rocket fuel powered micro thrusters as a high energy density actuation method for aerial micro robots. In a multi stage configuration these thrusters can be used for intermittent flight which can decrease the energetic cost ...
متن کاملExperience-specific functional modification of the dentate gyrus through adult neurogenesis: a critical period during an immature stage.
Neural circuits in the dentate gyrus are continuously modified by adult neurogenesis, whose level is affected by the animal's experience. However, it is not known whether this experience-dependent anatomical modification alters the functional properties of the dentate gyrus. Here, using the expression of immediate early gene products, c-fos and Zif268, as indicators of recently activated neuron...
متن کاملEngineering insect flight metabolics using immature stage implanted microfluidics.
Small-scale insect inspired aircraft represent a promising approach to downscaling traditional aircraft designs. Despite advancements in microfabrication, however, it has proven difficult to fully replicate the mechanical complexities that enable these natural systems. As an alternative, recent efforts have used implanted electrical, optical or acoustic microsystems to exert direct control over...
متن کاملpage translation and stage translation of drama texts
نمایشنامه به پیروی از ماهیت دوگانه اش، کارکردی دوگانه به خود می گیرد، بدین معنا که در هر دو نظام ادبی و تئاتری می تواند کارکردی مختص به خود یابد. هدف از انجام این پژوهش یافتن تفاوت ها میان ترجمه صفحه و ترجمه صحنه است.. پرسش مطرح شده عبارتست از: بر اساس مدل ارائه شده توسط لدوسر (1995)، تفاوت های ترجمه صفحه و ترجمه صحنه در چیست؟ یافته های این پژوهش حاکی از آن است که ترجمه صفحه به نمایشنامه ا...
