Every amplifier (speaker) has an electrical current. When the current is changing, it produces a magnetic field. To make the cone (or panel) of the speaker move, magnets are used to create an opposing magnetic field which creates vibrations. These vibrations are the sound we hear. Speakers often contain large magnets inside of them, as…

Working with the tiniest magnets, Hebrew University discovers a new magnetic phenomenon with industrial potential. For physicists, exploring the realm of the very, very small is a wonderland. Totally new and unexpected phenomena are discovered in the nanoscale, where materials as thin as 100 atoms are explored. Here, nature ceases to behave in a way…

This offers opportunities to discuss the discrepancies, deepen the relationship, and re-align values. Conversely, we may justify or trivialize negative behavior or even end the relationship. Koller and Salzberger (2007) developed an eight-item consumer behavior scale. Listening to a dull discussion was not worth the embarrassment of reading the obscene words, resulting in cognitive dissonance….
Studies indicate a strong relationship between participant retention at follow-up and the efficacy of pharmacological treatments in combination with behavioral interventions for MA patients [24, 25]. The review findings indicated that pharmacological treatments alone led to significant reductions in craving, withdrawal, psychosis and depression among amphetamine abusers [14–19]. If some medicines can reduce amphetamines-related symptoms,…
