This paper presents an underwater vehicle mimicking the undulating fins of fish. To mimic the actual flexible fins of real fish, a fin-like mechanism is modelled with a series of connecting linkages. By virtue of a specially designed strip, each link is able to turn and slide with respect to the adjacent link. The driving linkages are used to form a mechanical fin consisting of several fin segm...

Functional properties of protein from mantle and fin of the jumbo squid Dosidicus gigas were explained based on microscopic muscle fiber and protein fractions profiles as observed in SDS-PAGE. Fin has higher content of connective tissue and complex fiber arrangement, and we observed higher hardness of fin gels as expected. Myosin heavy chain (MHC) was found in sarcoplasmic, myofibril and solubl...

Small minimum temperature approach, large surface area per volume, high heat transfer efficiency and possibility of handling several streams of multi-stream plate-fin heat exchangers lead to more heat recovery and smaller heat exchanger size. Therefore, plate-fin heat exchangers have been applied extensively in sub-ambient processes. However, one major difficulty in optimising the design of pla...

Unsteady water flows are common in nature, yet the swimming performance of fishes is typically evaluated at constant, steady speeds in the laboratory. We examined how cyclic changes in water flow velocity affect the swimming performance and energetics of a labriform swimmer, the shiner surfperch, Cymatogaster aggregata, during station holding. Using intermittent-flow respirometry, we measured c...

In this work, we use an experimentally calibrated 3D quantum mechanically corrected device simulation to study the random dopant fluctuation (RDF) on DC characteristics of 16-nm-gate trapezoidal bulk fin-type field effect transistor (FinFET) devices. The fixed top-fin width, which is consistent with the realistic process by lithography, of trapezoidal bulk FinFET devices is considered in this s...

Tbx5 plays a pivotal role in vertebrate forelimb initiation, and loss-offunction experiments result in deformed or absent forelimbs in all taxa studied to date. Combining single-cell fate mapping and threedimensional cell tracking in the zebrafish, we describe a Tbx5adependent cell convergence pattern that is both asymmetric and topological within the fin-field lateral plate mesoderm during ear...

the distribution of yellowfin seabream populations in estuaries and inland rivers in coastal area of the persian gulf and strait of hormuz is presented. based on morphological and mersitic characteristics and also color pattern, these populations are assigned to the recently described sparid fish, acanthopagrus arabicus iwatsuki, 2013 which is distinguished by pelvic and anal fins vivid or stro...

Two new species of genus Leporinus from the Araguaia-Tocantins system, Amazon, Brazil, are described. Leporinus unitaeniatus n. sp. is distinguished from the remaining species of this genus by the presence of a conspicuous longitudinal dark brown bar along the lateral line on the flanks, and Leporinus geminis n. sp. is distinguished by an inconspicuous dark bar combined with three large and ver...

In the article concepts and facts necessary to continue formalization of theory of continuous lattices according to [11] are introduced. and [4] provide the notation and terminology for this paper. 1. PRELIMINARIES The following two propositions are true: (1) For all sets X, A, B such that A ∈ Fin X and B ⊆ A holds B ∈ Fin X. (2) For every set X and for every family F of subsets of X such that ...

Sinocyclocheilus brevifinus sp. nov. is described from a subterranean river at Maohedong Village, Guangxi Zhuang Autonomous Region, Southern China. The new species can be distinguished from all congeners in having functional eyes, last simple dorsal fin ray soft and without serrations along posterior margin, eye diameter small (3.4-5.0 %SL), tip of depressed dorsal fin not reaching vertical at ...
