Springs in Swimming Animals

Handedness helps homing in swimming and flying animals

Swimming and flying animals rely on their ability to home on mobile targets. In some fish, physiological handedness and homing correlate, and dolphins exhibit handedness in their listening response. Here, we explore theoretically whether the actuators, sensors, and controllers in these animals follow similar laws of self-regulation, and how handedness affects homing. We find that the acoustic s...

Convergent evolution in locomotory patterns of flying and swimming animals.

Locomotion is one of the major energetic costs faced by animals and various strategies have evolved to reduce its cost. Birds use interspersed periods of flapping and gliding to reduce the mechanical requirements of level flight while undergoing cyclical changes in flight altitude, known as undulating flight. Here we equipped free-ranging marine vertebrates with accelerometers and demonstrate t...

Alpha activity in Indian thermal springs

ABSTRACT Background: and soils with which it comes in contact. There is dual exposure from radon in water i.e. due toinhalation of the radon released from the water into the ambient air and through ingestion whenwater is used for drinking. As radon contaminated water adversely affects the health, it istherefore fundamental from health and hygiene point of view to measure radium concentrationand...

Role of hot springs’ hydrochemistry in Balneotherapy, Case Study: Fotoyeh and sanguyeh springs, western Hormozgan

Introduction: Hydrochemical properties of waters used in balneotherapy are very important, as they play a key role in success or failure of this kind of treatment. There are 30 mineral and hot spas in Hormozgan Province, Southern Iran, which are traditionally used for treating diseases. In this study, hydrochemical properties of Fotoyeh and Sanguyeh Springs, in western Hormozgan Province, are d...
