INTRODUCTION ▪ Two Peg Test is a surveying operation carried out to determine whether the levelling bubble and telescope line of sight are parallel. OBJECTIVE ▪ Peg Test is a surveying operation carried out to determine if the leveling bubble (bubble axis) and telescope line-of-sight (line of collimation) are parallel. THEORY ▪ By using the leveling method‚ work for establishing Temporary Bench Mark (TBM) was done ▪ Bench Mark (BM) must be known first. BM

the radiation. -Reactor: The reactor is the most important part of the process as it produces heat which forms steam to power the turbines therefore creating electricity. It uses uranium-235 or in some cases plutonium-239. -Control rods: Control rods are the component which makes nuclear fission stable and safe. They are placed in-between the fuel source to absorb any unwanted neutrons. These may be consist of many different elements but the most common used are silver-indium-cadmium alloys

Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

Academic study of problem solving and thinking related to everyday life Every day individuals are faced with many different problems for example deciding what to wear‚ finding a suitable place to park your car or even completing an assignment. Whatever the problem is‚ ‘problem solving is defined as any goal-directed sequence of cognitive operations’‚ as suggested by Anderson (1980‚ p.257). There has been a vast amount of research on human problem solving which has provided a better understanding

each other’s history. The Chinese ‘counting rods forms (2nd BCE to 4th CE) this was originally short bamboo rods used in written text’1 the counting rods it was roughly around 3-14cm in length and were simple‚ it was done by the use of small bamboo rods arranged to represent the numbers 1 to 9 making sense for the name (Counting rods/Rod numerals) . To note the Chinese numbering system dates to 2nd BCE which is before Indian numeral system. The way the rods were positioned was important because in

In the eyes of both humans and dogs‚ there are two main types of light-sensitive cells referred to as rods and cones. Cone cells enable you to see color. Rods work with black and white vision‚ so they’re better at identifying shades in dim light. Dogs are dichromats‚ which means they possess only two types of cones. This enables their brains to distinguish blue from yellow‚ but not red from green. Humans‚ on the other hand‚ are trichromatic. Our eyes contain three types of light-sensitive cones.
