of the hardened cement. These tests are done on cement – sand mortar and not on the hardened cement itself‚ the r eason of not using neat cement past on these test is in th e following two points: 1. Difficulties in molding (Getting good specimens). 2. Large variability of test results. It is important that the resul tant mixture (Cement + sand + water) has the same properties as concrete. So the standard sand was chosen and the following properties were determined to it: 1. Consist

Compare and contrast the use of light and electron microscopes in biological studies. Microscopes are laboratory equipment which are used to observe any matter that is too small to be seen by the naked eye. There are several types of microscopes – the two most common being the optical microscope‚ also known as a light microscope‚ and the electron microscope‚ which can be either a transmission electron microscope (TEM) or a scanning electron microscope (SEM). There are more differences than similarities

determine the best course of treatment based on the sensitivity of the bacteria to particular antibiotics. One of the most frustrating problems plaguing hospitals is the increased rate at which blood culture results are being returned as contaminated specimens. These results can lead to a significant increase in cost to the hospital and patient as well as an increased length in hospital stay and the administration of unnecessary antibiotics. The Center for Medicare Services (CMS) has recently implemented

ENGINEERING LABORATORY III (BDA 27101) TOPIC 1: TENSILE TEST 1. INTRODUCTION The tensile experiment is the most common mechanical test that reveals several important mechanical properties‚ such as: modulus of elasticity‚ yield strength‚ ultimate tensile strength‚ ductility‚ and toughness. The material to be tested is formed into a shape suitable for gripping in the testing machine‚ and then pulled at constant rate until it fractures. The tensile instrument elongates the specimen at a constant
