Female adult specimens of the pennellid copepod Peniculus minuticaudae Shiino, 1956 were collected from the fins of two species of monacanthid fishes, threadsail filefish (Stephanolepis cirrhifer) and black scraper (Thamnaconus modestus), cultured in floating cages in Japan. These collections represent the first records of P. minuticaudae from farmed marine fishes as well as the first records o...

Swimming and flying animals generate unsteady locomotive forces by delivering net momentum into the fluid wake. Hence, swimming and flying forces can be quantified by measuring the momentum of animal wakes. A recently developed model provides an approach to empirically deduce swimming and flying forces based on the measurement of velocity and vortex added-mass in the animal wake. The model is c...

this study was conducted to examine morphometric and meristic characteristics alongside pigmentation patterns of bream larvae, abramis brama orientalis, in four stages of larval development. morphological characters including total length (tl), standard length (sl), notochord length (nl), head length (hl), head depth (hd), eye diameter (ed) and mouth width (mw) were examined from hatching time ...

Adhesive apparatus is the modifications of the skin of the ventral surface. Fast water current is the single most important limiting factor deciding the occurrence and survival of fauna and flora unless equipped with special adaptive features to with-stand the vicissitudes of nature. In hillstream fishes, the presence of adaptive modifications in their body organization is of prime importance f...

The principal purpose of the present article is to examine a fractional model of convective radial fins having constant and temperature-dependent thermal conductivity. In order to solve fractional order energy balance equation, a numerical algorithm namely homotopy analysis transform method is considered. The fin temperature is derived in terms of thermo-geometric fin parameter. Our method is n...

The performance of a heatsink with and without staggered fins is analyzed in the present work. The effect of flow resistance on thermal behavior of staggered plate heatsinks were analyzed in the present study. Ansys FLUENT has been used for the present simulation. Authors have used three different models with and without staggered arrangement. The result shows advantage of staggered heat sink o...

In this paper, recent advances in the design of feedback laws for the 3D movement of an Eel-like robot are presented. Such a robot is under construction in the context of a national French robotic project. The proposed feedback enables the tracking of a desired 3D position of the Eel head as well as the stabilization of the rolling angle without using pectoral fins. We build on a previous work ...
