Video Essay Self-Centering in Cytoplasmic Fragments of Melanophores1□V
The radial array of cytoplasmic microtubules (MTs) provides routes for intracellular transport and defines spatial organization of cytoplasm through interaction with molecular motors bound to membrane organelles (Kellogg et al., 1994; Hirokawa, 1998). The array is believed to be organized by the centrosome, which is capable of nucleating MTs. Our recent studies of pigment transport (Rodionov an...
متن کاملOptimum Design of Self Centering Grippers
Scopul sintezei cinematice a mecanismelor este determinarea dimensiunilor elementelor componente, în condiţiile impuse prin mişcările unor puncte sau elemente. Rezolvarea unei astfel de probleme se reduce la rezolvarea unui sistem de ecuaţii neliniare. Ca urnare, problemele de sinteză cinematică nu au soluţii unice. Pentru oprimizarea dimensiunilor unui mecanism de prehensiune, funcţia obiectiv...

تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...
15 صفحه اولNonlocal mechanism of self-organization and centering of microtubule asters.
Fragments of fish melanophore cells can form and center aggregates of pigment granules by dynein-motor-driven transport along a self-organized radial array of microtubules (MTs). We present a quantitative model that describes pigment aggregation and MT-aster self-organization and the subsequent centering of both structures. The model is based on the observations that MTs are immobile and treadm...
