purpose of this lab‚ it is quite useful to fully understand the following terms: optical rotation and carbohydrate. Optical rotation is measured by a polarimeter‚ which measures the polarization of light and the rotation of polarized light (influenced by enzymes). It is dependent on the concentration of sample‚ temperature‚ length of the tube and the observed rotation. The +/- degrees of the optical rotation determines the presence of d- and l- enantiomers. Finally‚ a

Gender Differences in Mental Rotation Abstract The general research topic for this were the sex differences in mental rotation. Twenty- five female students and five male students were assigned to different treatment conditions and were tested on their response time and accuracy in the different mental rotation conditions. It was hypothesized that lateralization between genders would effect the results based on stimulus type. Males were expected to perform better‚ both in accuracy and speed

The speed of an asynchronous motor rotating field and thus its rotor speed depends on the number of pairs of poles in the stator field .the rotor speeds n are lower than the table values by the amount of the relevant slip speed ns. Motors are designed with up to three stators windings‚ which have different number of pairs of poles. They can therefore run at up to pairs of poles. They can be in any desired ratio to one another. A pole-changing switch is used to changing poles for the desires speed

Explain why did‚ the Menshevik and Bolshevik split happened in 1903? Until 1903 the Bolsheviks and the Mensheviks were a single party called the Social democrats. They wanted a communist Russia‚ following the ideas of Marxism. However with in the party of the social democrats there were two men‚ Lenin and Plekhanov whom of which had two completely different ideas on how the party was going to be successful in achieving the revolution‚ causing a split in the social democrats. Both parties’ were

CHAPTER 6: Training and Development Training begins at an elementary level‚ often teaching basic literacy and mathematics skills before offering instruction in specific job skills. The nature of work is changing. We can no longer count on learning one job and keeping it until retirement. We must learn to think not only of a single chosen career over a lifetime‚ but of several careers from which we master a cluster of skills that must be continually upgraded. Careers of the future will require

which a child develops at as they grow into young adults. Physical Development The two main areas of physical development are gross & fine motor skills. Gross motor skills use the larger muscles in the body like arms & legs. Rolling over‚ crawling‚ walking‚ running and jumping are all gross motor skills. Fine motor skills use the smaller muscles in the body‚ like fingers & toes. Writing‚ painting‚ pointing‚ grasping and reaching are examples of fine motor skills. Fine motor skills alsto eye

"The light begins…the light ends" Dulce Maldonado Abstract: In this lab the students did two labs in which they learned the process of photosynthesis‚ which involves the use of light energy to convert carbon dioxide and water into sugar‚ oxygen‚ and other organic compounds. Oxygen is released as a product. This process is often summarized by the following reaction: 6CO2 + 12H2O ------> C6H12O6 + 6H2O + 6O2 The energy of photosynthesis comes from absorbed photons found in light and involves

An intelligent student is a teacher’s pride. No other feelings can be compared to the joy it has‚ knowing that he’s been teaching learners who are fast in comprehending. A homogenous group leaning not all on the teachers’ teaching but are motivated in learning by their own sweaty effort. Their culture is precisely far more different than those of other students. The flow of their thoughts‚ the sarcasm of their speeches and the intangibility of their behaviors puzzled their mentor’s mind and even
