Bending Properties of Tail Flukes of Dolphin*
The aim of this paper is to study the bending properties of tail flukes of a dolphin. The bending test was carried out to obtain the displacements on different test points of a fluke. The Young’s moduli of the ligamentous layer and the dense connective tissue in the flukes were obtained from the tensile test and the compression test. In order to establish an FEM model for bending deformation of...
متن کاملAnalysis on Swimming Behavior of Dolphin with Artificial Tail Flukes
Dolphins have high propulsion and maneuvering performances. Dolphin’s tail flukes play an important role to generate propulsive force. We paid attention to a dolphin that lost most part of its tail flukes by disease kept in an aquarium, Okinawa, Japan. The dolphin could swim by attaching artificial tail flukes as well as a normal dolphin. The objective of this study is to discuss the effectiven...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولIntervention to Improve the Quality of Life of a Bottlenose Dolphin That Developed Necrosis on the Tail Flukes
[Purpose, Case, and Methods] A female bottlenose dolphin (Tursiops truncatus) in captivity developed necrosis of the tail flukes. Although the diseased site healed after surgical resection, the loss of approximately 75% of the tail greatly affected her swimming performance. To restore swimming ability, we developed artificial tail flukes as a prosthetic swimming aid and provided physical therap...
متن کاملThe Mechanical Properties of Rat Tail Tendon
The load-strain and stress-relaxation behavior of wet rat tail tendon has been examined with respect to the parameters strain, rate of straining, and temperature. It is found that this mechanical behavior is reproducible after resting tile tendon for a few minutes after each extension so long as the strain does not exceed about 4 per cent. If this strain is exceeded, the tendon becomes progress...
