Catching Fish and Avoiding Sharks
Although researchers agree that the first 5 years of life are critical for children’s developing executive functions (EFs), further advances are hindered by a lack of consensus on the design and selection of developmentally appropriate EF tasks for young children.

Due to their successfulness, a strict control program has been changed to a management program in order to keep numbers below the level at which intolerable damage occurs. The territory of the Net...
متن کاملMathematical model of echolocation of fish-catching bats
The ability of bats to prey on the insects and catch fish on thewing bymeans of echolocation is remarkable, since the acoustic power transmission through air–water interface is very small. A mathematical model describing the way in which a bat can detect fish under the water surface is suggested in this article. The problem of scattering of the spherical acoustical wave from the water with the ...
متن کاملMuskrat Control and Damage Prevention
Although the muskrat, Ondatra zibethica, is native throughout most of the United States and has been a mainstay of the fur business, in recent years it has become a serious pest causing extensive damage to some specific crops, as well as to earthen water-holding structures.
