devices. It’s also important because it allows for minimal errors and mistakes that could‚ if not‚ contribute wrong readings and conclusions. In testing for the calibration of speed‚ the values in trial 1‚ 2 and 3 were very similar to the adjusted level of speed on the treadmill. The speed level in trial 1 was 1.0 mph‚ which yielded a measured value of 1.06 mi/hr. Trial 2 was 3.0 mph‚ which yielded 3.2 mi/hr and tiral 3 was 4.0 mph‚ which yielded 4.3 mi/hr. Although the measured values yielded a few points

Mechanism 4 shows the debromination of 2α-bromocholestan-3-one to give 4. This mechanism which is similar to a Favoskii rearrangement‚ is likely to go via this path as other research has shown that there is often a by-product with this reaction. The by-product is cholest-4-en-3-one which requires the intermediate seen in the third molecule in the above mechanism. The intermediate is highly strained and with the presence of base a proton will be extracted which aids the collapse of the three membered

Splice enclosures can be typically place in one of the two following categories. 1. Radial Splice Enclosures – radial splice enclosures have cables enter and exit the enclosure on the same side. 2. Axial Splice Enclosures – Axial splice enclosures have cables enter and exit on opposite ends of the enclosure. Enclosures designed for

[pic] = an − bn. Theorem: If 2n + 1 is an odd prime‚ then n is a power of 2. proof: If n is a positive integer but not a power of 2‚ then n = rs where [pic]‚ [pic]and s is odd. By the preceding lemma‚ for positive integer m‚ [pic] where [pic]means "evenly divides". Substituting a = 2r‚ b = − 1‚ and m = s and using that s is odd‚ [pic] and thus [pic] Because 1 < 2r + 1 < 2n + 1‚ it follows that 2n + 1 is not prime. Therefore‚ by contraposition n must
