3.2 “Lab-on-a-Chip” A Lab-on-a-Chip (LOC) device‚ also known as a micro-total-analytical system (microTAS) or microfluidics device‚ is a device that can integrate miniaturized laboratory functions (such as separation and analysis of components of a mixture) on a single microprocessor chip using extremely small fluid volumes on the order of nanoliters to picoliters. From a technology categorization perspective‚ LOCs can be viewed as a subset of microelectromechanical systems (MEMS) and combine

CASE STUDY - TRAUMA 1. What is the difference between a primary and secondary survey? (4 points) - Primary Survey = This is pre-hospital resuscitation done to quickly identify and begin treating life threatening injuries in the field. This uses an ABCDE approach - Secondary Survey = This is hospital resuscitation‚ a more in depth system by system process after arrival to the hospital. It includes a complete head to toe assessment which helps identify other injuries

CARE STUDY Assessing patients systematically and being able to interpret the findings is an essential aspect of nursing because it allows their care to be prioritised appropriately and alleviate the process of their recovery or treatment through the ability to recognise and carry out suitable care plan‚ based on their needs and preferences (NICE‚2007). It allows the early management of diseases‚ illnesses or emergency situations and leads to patient safety‚ positive clinical outcome‚ and avoidable

EXPERIMENT 1 – HEAD LOSSES IN PIPES Introduction: In this experiment‚ the aim is to find the losses of water flow in a pipe system.There are two types of losses. First the major losses which is caused by the the frictional effect of pipe. Second one is the minor losses which is caused by the turning points(corners) of pipes. Apparatus: • • • • • • 90° mitter bend 90° elbow bend 90° large radius bend Sudden enlargement in pipe diameter Sudden contraction in pipe diameter A pump to supply water

Charles’s Law Prepared by H. A. Neidig‚ Lebanon Valley College‚ and N. Spencer‚ Franklin and Marshall College PURPOSE OF THE EXPERIMENT Establish the relationship between the volume of a gas and the temperature of a gas at constant pressure. Verify Charles’s law. BACKGROUND INFORMATION The volume of a gas at constant pressure increases when the temperature of the gas is raised. This observation was first made by Jacques A. C. Charles in 1787. A quantitative study did not follow‚ however
