6. CHARACTERIZATION AND EVALUATION OF PROPOFOL MICROEMULSION 6.1CHARACTERIZATION OF MICROEMULSION 6.1.1 PARTICLE SIZE The particle size characterisation of microemulsion was performed to obtain information about the main particle size of the systems, particle size distribution and about changes over time [54-55]. Particle size is the most important characteristics of microemulsion system. It influences the drug loading, drug release, and stability of microemulsion. Drug release is affected by particle

is. Income per capita can be used to measure the economic and social development, but not any of the other factors of development, such as environmental development. Development can be further measured by income inequality. This can be a useful measurement as it shows the differences between the rich and poor. The greater the inequality, gap between the rich and poor, the worse developed the country is. However, income inequality doesn’t give the actual amount of money in the country, so economic

Automated Swell Index Measurements of Films Using THERMO MECHANICAL ANALYZER (TMA) SWAYAJITH SAHADEVAN swayajith@gmail.com Abstract Dimensional instability on finished plastics products due to changes in humidity is one of the leading causes of product failure. The test lead times associated with measuring changes in dimensions due to humidity changes are prohibitively longer & lot of machine time is consumed in the process. This can become a limiting scenario wherein multiple materials

Health & Quality Of Life Outcomes INTRODUCTION This research article explains the newfound ability to assess patients with a Patient-reported outcome, or PRO. Particularly in this study, the PROs are focused on Pressure Ulcers, or PU. These are “chronic wounds found on the skin or underlying tissue as a result of pressure” (2) By using a frame of questions and interviews

The Paper Towel Experiment. I remember watching certain television commercials when I was kid about the absorbency and strength of paper towels. They seemed to always focus on people trying to wipe up large amounts of water and most of being dumped onto the floor or wet paper towels being stretched out and weight being applied and falling through immediately. Ultimately it was the thickest and newest paper towel that wiped up all the water without spilling any and held the weight. Even as

Omar Jamil Applied Science CW Instrument: Light Microscope - A microscope that uses visible light and lenses to magnify images of small samples. Basic rules to using and calibrating the microscope: 1. You should always carry a microscope with two hands, one on the arm and the other under the base. 2. You should always start on the lowest power objective lens and should always leave on the microscope on the

ability of a measurement to match the actual value of the quantity being measured". If in reality it is 34.0 F outside and a temperature sensor reads 34.0 F, then than sensor is accurate. Precision Precision refers to how well experimental values agree with each other. If you hit a bull’s-eye precisely, then you are able to hit the same spot on the target each time, even though that spot may be distant from the center. Precision is defined as, "(1) The ability of a measurement to be consistently
