ofThe present invention is a trap selector for selecting an optimum trap meeting various uses which is designed to sequentially input required data for selecting the trap and to execute previously memorized trap-selecting programs by a microcomputer characterized in that the geometrical conditions of ...
The present invention relates to new and useful improvements in animal traps and more particularly to improvements in a trap having pivoted spring-operated jaws for trapping animals, such as muskrats and the like. An object of the invention is to provide a trap, of the above type, wherein...
The improvements in a collapsible fish trap of the present invention include a flotation collar releasably secured around the flared neck of the trap above the fish-holding chamber in the trap, as by latch means in the form of one or mor... E Sawlsville - US 被引量: 23发表: 1981年 ...

A new type of insect trap which may be used for fighting not only olive flies but also any other kind of insect. According the present invention, the new trap is comprised of a level surface 15 x 20 cm. (or any other dimension) which may be made of plywood, wood, plastic, carton ...
Examples of a Poverty Trap One of the most important considerations in studying the poverty trap is the amount of government aid necessary to lift a family out of their present conditions. Consider the case of a family of four, made up of parents and two children who are below legal working...
It was confirmed that the present cross section data are consistent with previous data and the values estimated by some scaling formula. 展开 关键词: instrumentation related to nuclear science and technology argon ions collisions computerized simulation cross sections energy spectra ev range forbidden ...
Here we present the realization of a motility-trap for active particles, which only exploits their self-propulsion properties. By combining experiments, numerical simulations, and theory, we show that, under appropriate conditions, a force-free rotation of the self-propulsion direction towards the ...
Because of the fact that water as a constantly surrounding medium enabling for prey-triggered and spontaneous suction may not be permanently present, the question arises whether traps of non-aquatic species function similarly to those of aquatic species, or if functional and/or structural differences...
We present a novel type of dark spontaneous-force optical trap. The trap is based on a velocity-selective inhibition of repumping light absorption produced... C Fort,FS Cataliotti,M Prevedelli,... - 《Optics Letters》 被引量: 10发表: 1997年 Cesium-137 distribution in soil and Leccinum au...
