ترجمه بخشی از کتاب "critical readings in translation studies"
چکیده در دنیای پیچیده ی امروز، تغییرات زیادی در زندگی بشری در حال وقوع اند و شاهد رقابت های بسیار فشرده ی جوامع در دستیابی به فناوری برتر و قدرت بیشترهستیم. به نظر می رسد که فرد وجامعه مجبورند به طریقی در وضعیت خویش دگرگونی ایجاد کنند تا از قافله ی علم، فناوری، و پیشرفت عقب نمانند. رشته مطالعات ترجمه نیز از این قاعده مستثنا نیست. علی رغم وسعت روز افزون پژوهش در این حوزه و میان رشته ای بودن مطال...
Galvanotropism in the Earthworm
In a former paper Kellogg and the writer have described the effects of a galvanic current on the body positions of Lumbricus Ierres~ris. 1 When the current flows transversely through such an animal or piece of one, the muscles respond by unilateral contraction on the cathodal side. The result is to bring the ends of the worm toward the cathode, thus forming a U with the median part nearest the ...
متن کاملBrownian Earthworm
We prove that the distance between two reflected Brownian motions outside a sphere in a 3-dimensional flat torus does not converge to 0, a.s., if the radius of the sphere is sufficiently small, relative to the size of the torus.
متن کاملSomatic Muscle in the Earthworm
Neuromuscular transmission in invertebrates has been studied extensively (see Bullock & Horridge, 1965). However, the neuromuscular junctions in the earthworm have only been studied by Horridge & Robertes (i960). The present experiments were carried out to investigate the transmission in the neuromuscular junctions which could be recorded from the postsynaptic membranes of the longitudinal musc...
متن کاملInfluence of ground cover on earthworm communities in an unmanaged beech forest: linear gradient studies
Micro-scale changes in earthworm communities and ground cover types were studied along five transect lines in an unmanaged beech forest (Fontainebleau forest, France). Spatial patterns were interpreted to the light of interactions between earthworm species and forest architecture, ground vegetation and quantity as well as quality of litter. The anecic Lumbricus terrestris was associated with pa...
