Flower induction in mango (SAMPLE) Introduction: Different mango varieties naturally produce fruit every other year. That is‚ there are years or seasons in which a tree or the crop may be very not efficient‚ producing almost no fruits. For trees to be productive annually‚ flower inducers are used to stimulate flower growth during the ‘off’ seasons of the tree variety. Inducers increase number of viable blooms for increased production and harvest. Inducers work best on healthy‚ mature trees under

Discuss one or more socio-psychological explanations of aggression. (24 marks) Social learning theory (SLT) is just one of the few theories that attempt to explain aggression‚ in regards to social psychology. SLT implies that all behaviours are learned‚ and that is by watching‚ or ‘observing’ others. Therefore children learn aggressive behaviours by observing others aggressive behaviours. However‚ it is not that simple. For a child to learn this‚ they must first notice a potential role model

Often times lines become blurred regarding inductions and deductive reasoning as they apply to forensic sciences. Inductions are described by Thornton (1997b‚ p. 13) as an inference that is derived by specific observations to a generalization‚ or an assumption that may not always be valid. On the other hand‚ a deductive reasoning is defined as a forensics-evidence-based‚ process-oriented method of investigative reasoning based off of the behavioral patterns of a particular offender (Turvey‚ 1999)

Three-phase induction machines account for the great majority of applications that call for motors with power ratings over 5 hp. They are used to power pumps‚ fans‚ compressors‚ and grinders‚ and in other industrial applications. Rotating Stator Field. The stator of a three-phase induction machine contains a set of windings to which three-phase electrical power is applied. The stator field can be visualized as a set of north and south poles rotating around the circumference of the stator. (North
