Physics 4052 Spring 2004 Y. Kubota K. Wick Project Proposal for Physics 4052 Introduction You must begin to think about a possible experimental project to carry out next semester (Physics 4052). The reason for this is two-fold: first‚ it will introduce you to the process of proposal writing‚ which is an unavoidable and very important part of modern experimentation‚ and second‚ it will enable us to make any necessary plans for procuring equipment. To start you thinking about this process‚

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

Common Appraisal Errors Error Contrast Effect Definition Tendency of a rater to evaluate people in comparison with other individuals rather than against the standards for the job Example Think of the most attractive person you know and rate this person on a scale of 1 to 10. Now think of your favorite glamorous movie star. Rerate your acquaintance. If you rated your friend lower the second time‚ contrast effect is at work. A new supervisor noticed an employee who was going through a divorce performing

Purpose: To find the initial velocity of a marble leaving a ramp using time‚ range‚ and background information learned in class. Equipment: The equipment used in this experiment was a toy track and ramp‚ a small marble‚ multiple Physics textbooks‚ meter sticks‚ bright-colored cardstock‚ masking tape‚ sidewalk chalk‚ plastic bag and a cloth. Procedure: Our experimental values include the height that the marble would travel‚ y= 88.1 cm‚ and our ramp angle‚ θ= 44.0°. These independent variables

PHYS 221 Experiment M10 Harmonic Motion of a simple Pendulum Jacob LaMarre Group members: Josh‚ Courtney‚ Ashley Abstract: Determine the acceleration due to gravity using a pendulum. Introduction: A simple pendulum consists of a mass suspended by a length of string. When set Oscillating‚ the mass will have a period “T” given by the following equation. This equation shows the only variables that affect the rate at which the pendulum swings is the length “l” that is measured to the center

Introduction Medication errors have been a problem in the medical field for many years. Medication errors are one of the most common types of error in the health-care field that affects the lives and safety of the patient (Schoenecker‚ 2007). The prevention of medication errors is possible‚ if the nurse uses the medication rights correctly during the administration process. Medication administration is a process that involves the ordering and distribution of medicines to the patient. It also involves

Unlike Incident Management metrics like "percentage solved within target time"‚ Problem Management metrics are typically not included explicitly in Service Level Agreements (SLAs). Setting up a Known Error Database (KEDB) is another key activity. A Known Error is a Problem that has a documented root cause and workaround or solution. The KEDB maintains information about problems (i.e.‚ isolation and resolution procedures) and the appropriate workarounds‚ scripts‚ references to

Introduction of Physics: Physics ("knowledge of nature") is the science concerned with the discovery and understanding of the most basic fundamental laws of the universe that control the way everything in the world around us behaves. Discoveries in basic physics have important ramifications for all of science. Physics attempts to describe the natural world by the application of logic scientific methods‚ including modeling by theoreticians. As a core scientific discipline‚ physics is concerned with
