Induction motorAn induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable, and economical.
Émotion (zoologie)vignette|Un dessin d'un chat par T. W. Wood dans le livre de Charles Darwin, The Expression of the Emotions in Man and Animals, décrit comme agissant «dans un état d'esprit affectueux» L'émotion en zoologie désigne les sentiments et émotions subjectifs éprouvés par des animaux non-humains. Les émotions peuvent être décrites comme des états conscients, subjectifs caractérisés premièrement par les expressions psychophysiologiques, les réactions biologiques, et les états mentaux.
Neurosciences socialesLes neurosciences sociales peuvent se définir comme l’exploration empirique, ancrée dans la biologie et les neurosciences, des phénomènes traditionnellement examinés par la psychologie sociale. Les comportements altruistes, sexuels, d’affiliation, de coopération, de compétition, de persuasion, la moralité, l’obéissance, la violence, l'agression, l'empathie, les biais raciaux sont quelques exemples des domaines étudiés.
EfficacyEfficacy is the ability to perform a task to a satisfactory or expected degree. The word comes from the same roots as effectiveness, and it has often been used synonymously, although in pharmacology a distinction is now often made between efficacy and effectiveness. The word efficacy is used in pharmacology and medicine to refer both to the maximum response achievable from a pharmaceutical drug in research settings, and to the capacity for sufficient therapeutic effect or beneficial change in clinical settings.
Animals in spaceAnimals in space originally served to test the survivability of spaceflight, before human spaceflights were attempted. Later, other non-human animals were flown to investigate various biological processes and the effects microgravity and space flight might have on them. Bioastronautics is an area of bioengineering research that spans the study and support of life in space. To date, seven national space programs have flown animals into space: the United States, Soviet Union, France, Argentina, China, Japan and Iran.
