ABSTRACT Two reduced n-heptane mechanisms, previously developed in 1998 (40 species and 165 reactions) and in 2000 (65 species and 273 reactions) respectively, were revisited and the mechanism improvement was pursued. In the newly revised version, the mechanism consists of 83 species and 445 reactions. The mechanism was validated against the auto-ignition delay times of n-heptane/air mixture me...

BACKGROUND Generation of membrane curvature is critical for the formation of plasma membrane protrusions and invaginations and for shaping intracellular organelles. Among the central regulators of membrane dynamics are the BAR superfamily domains, which deform membranes into tubular structures. In contrast to the relatively well characterized BAR and F-BAR domains that promote the formation of ...

The dimensional synthesis is done by using Genetic Algorithm to achieve a desired trajectory. Three problems are analyzed having different curvature. The program is authored in MATLAB ® 2010a. The error is seen to be in the permissible prescribed limit. The prototyping of straight line trajectory analysis is also done in ADAMS ® .

Passive linkages were developed to improve grasp functionality and minimize a prosthetic terminal device's number of user-controlled inputs. The linkages act to stabilize grasped objects and substitute for the palp of normal anatomical fingers. The Southampton Hand Assessment Procedure was used to compare the normal anatomical hand, this prototype, and a commercially available (Hosmer) hook. In...

In transformed tobacco (Nicotiana tabacum) plastids, we flank the marker genes with recombinase target sites to facilitate their posttransformation excision. The P1 phage loxP sites are identical 34-bp direct repeats, whereas the phiC31 phage attB/attP sites are 54- and 215-bp sequences with partial homology within the 54-bp region. Deletions in the plastid genome are known to occur by recombin...

This paper concentrates on the application of fuzzy logic based on Taguchi method (FLTM) for multiobjective optimization of the small-length flexural pivot (belongs to link 4) in partially four bar-compliant mechanisms. The input parameters such as the input torque and the crank angle of link 2 were optimized with considerations of the multiple performance measures as angular displacement and s...
