چکیده

In the present work, graphical enumeration technique is applied for structural synthesis of mechanically constrained planar parallel robot formed by single loop 6bar chain or two 3R chains. Two RR chains are added to the considered system to mechanically constraint the movement of its end-effector. Structural code has been proposed as a new systematic methodology to detect isomorphic graphs. Therefore, 32 non-isomorphic graphs are obtained from this enumeration process. All these graphs represent one-degree-of freedom eight-bar mechanisms. Reverse transformation process is presented to obtain the corresponding linkage diagrams for all results. Keywordsstructural synthesis, eight-bar linkages, parallel robot, graphical enumeration

Structural-functional studies of peptides derived from a long-chain snake neurotoxin Naja naja oxiana

Introduction: The design and structural characterization of mini-proteins with a compact, folded structure provide insight into the complex architecture of proteins today and has long been a challenging issue in structural- functional studies. Alpha neurotoxins from snake venom have a distinct folded structure comprised of a disulphide core and three loops or “fingers” each of these loops are c...

PREPARATION OF NANO-STRUCTURAL Al2O3-TiB2 IN-SITU COMPOSITE USING MECHANICALLY ACTIVATED COMBUSTION SYNTHESIS FOLLOWED BYINTENSIVE MILLING

Abstract: Nano-structural synthesized materials can be fabricated utilizing intensive milling after combustion synthesis. The Al2O3-TiB2 ceramic composite has been synthesized by aluminothermic reactions between Al, Ti (TiO2), and B (B2O3 or H3BO3). Boric acid (H3BO3) is less expensive than boron oxide, and after being dehydrated at 200°C, boron oxide will be obtained. In this study, Al, TiO2, ...
