In his lab, Lohmann places hatchlings in a water tank surrounded by some electromagnet coils. In 1991, he found that the babies started swimming in the opposite direction if he used the coils to reverse the direction of the magnetic field around them. > Later, Lohmann found that hatchlings...
A contactor has a body constituted by a base common to two parallel walls each having on its internal face a rib to guide fixed elements of a removable electro-magnet having means to cooperate with the ribs. The fixed elements form a slide having resilient locking means cooperating with stop...
drum, membranophone, tympan - a musical percussion instrument; usually consists of a hollow cylinder with a membrane stretched across each end membrane - a thin pliable sheet of material 33. head - oral stimulation of the genitals; "they say he gives good head" oral sex sexual perversion, pe...
This invention relates to improvements in statistical machines and has for a principal object the provision of an adding machine having electrically operated controls associated with the keys of the a
This German-language questionnaire consists of 90 items and is designed for the ages 10–20 years. An experimenter ensured the understanding of all items and response schemes also by younger children. T-scores were built for the use of adaptive and maladaptive strategies based on the T-norms ...
and demonstrates this by using it to swing a pendulum. The third station then ties this to the action of a speaker, which is effectively a fancy electromagnet—and demonstrates how it creates sound waves in this way. Finally, the fourth station demonstrates the use of a microphone to record...
Each neutralization line consists of metal strip and in the middle of antenna elements a reactive component attached. This study proposes a low-cost, low-profile, miniaturized two-element-based MIMO antenna system with significantly reduced mutual coupling of S21 < − 36 dB. The antenna ...
FIG. 3 depicts use of a common core element extending from a solenoid coil over a first magnetic source to an adjacent opposite pole magnetic source; FIG. 4A-4C depict top, oblique, and side views of an exemplary ring magnet programmed with an alternating polarity pattern of 24 poles in a...
An electromagnetic shielding contact member 140 fitted near the plug inserting opening within the receptacle case 132 consists of a short column having a conical shape at the tip. The conical part at the tip of this electromagnetic shielding contact member 140 is engageable with the locking part ...
The electromagnet envisaged by this invention consists of yokes and an armature, moveable in relation to each other, and a winding surrounding a section of the magnetic circuit, the said armature bearing a permanent magnet fitted on its two pole faces with two pole pieces projecting beyond the ...
