YAMBAO‚ Monn Juleuse F. mjfyambao@gmail.com E304: Kundt’s Tube: Velocity of Sound in Solid METHODOLOGY Two experiments were done last time due to some circumstances that made the class to lack time and to be late compared to the official class syllabus. The students were able to accomplished the job by equally dividing the time into two. The first experiment was about Kundt’s tube. In this experiment‚ longitudinal sound waves will be produced in a metal rod and an air column. Using the properties

Introduction The 14-French (F) pigtail catheters (PCs) are small-caliber catheters that are percutaneously placed at bedside‚ in comparison with the tradition large-caliber (32-40F) chest tubes (CTs) that are placed by an open cut-down technique 1-3. The PC’s roles and its effectiveness in the management of trauma patients with pneumothorax 3 and hemothorax (HTX)/hemopneumothorax (HPTX) 4 have previously been published. It is controversial and many clinicians still question whether or not blood

broken. Transfer the mixture to a centrifuge tube to separate the sample into layers‚ to help remove the water. Once the sample is finished spinning extract the organic layer and place in a test tube. TLC: To determine which mixture acetone and hexane is the best developing solvent the first step is to make mixtures of these solvents in test tubes. In the first test tube mix one part acetone (.5 mL) and three parts hexane (1.5 mL)‚ In the second test tube mix two parts acetone (1 mL) and two parts
