phase diagram - ... However, the temperature probe notices the first changes in temperature, and from the data points collected one can determine when the slope of the graph starts to plane, and therefore determine when crystallization occurs. Furthermore, the ice water bath had a tendency to cause some condensation on the outside of the beaker, which at times made it difficult to see what was happening in the test tube containing the solution. Crystallization starts near the walls, and on the surface of the solution making it impossible to see if there is more than one set of crystallization temperatures for a mixture....   [tags: Chemistry]

Hertzsprung-russell Diagram - The Hertzsprung-Russell Diagram or, the H-R Diagram for short, is a graph which plots stars according to their temperature and absolute magnitude. This graph reveals a pattern, which in fact is quite interesting. The H-R Diagram is named for the two astronomers, Ejnar Hertzsprung and Henry Russell, who discovered this pattern of stars. These two astronomers independently discovered that comparing magnitudes and spectral class (color) of stars yielded a lot of information about them. One key purpose of the H-R diagram is to show the relationship between temperature and absolute magnitude of stars....   [tags: essays research papers] 510 words

Top-Down Approach to Drawing Data Flow Diagrams - The top-down approach to drawing data flow diagrams essentially involves moving “from the general to the specific” in terms of the detail level displayed (Kendall & Kendall, 2008, p. 220). Using information gathered from interviews, investigation, and personal observation, the systems analyst begins by developing a list of business activities. They then use the list to define the four elements of a data flow diagram, as follows: § External entities – send/receive data to/from the system § Data flows – the movement of data § Processes – the change or transformation of data § Data stores – a virtual storehouse where data can be added, examined, or retrieved (Kendall & Kendall, 2008) The analyst continues by creating a context diagram which only shows external entities and basic data flows into and out of the system....   [tags: Systems Analysis]

This is a classic case of a patient that is denied prompt care regardless if she asked for it or not. This form of neglect is appalling and could have been prevented had the nursing staff been attentive to her needs. Barriers Affecting Quality Care When it comes to quality care in health care facilities, it is found that nurse staffing plays an integral role in process barriers that may occur.....   [tags: Healthcare]

Solenoid - Summary of Investigation An investigation was carried out to find out the relationship between the force created in a wire (or solenoid) when current flowed through it and the force from gravity. This was investigated by connecting a solenoid up to a variable power pack and then placing a light ring of either copper or aluminum around the solenoid. When the current flows through the solenoid, a magnetic force created from the solenoid should make the ring 'jump' up or levitate. When carrying out the experiment, the assumption was made that there will be some movement from the ring when current starts flowing through the solenoid and thus a magnetic field will be present....   [tags: essays research papers] 1226 words

Macroeconomic Equilibrium - Macroeconomic Equilibrium Introduction Macroeconomic equilibrium for an economy in the short run is established when aggregate demand intersects with short-run aggregate supply. At the price level Pe, the aggregate demand for goods and services is equal to the aggregate supply of output. The output and the general price level in the economy will tend to adjust towards this equilibrium position. If the price level is too high, there will be an excess supply of output. If the price level is below equilibrium, there will be excess demand in the short run....   [tags: Economics] 1789 words

Investigating the Concentration of Sucrose in Cells of Carrots and Potatoes - Investigating the Concentration of Sucrose in Cells of Carrots and Potatoes Plan Introduction Osmosis is defined as 'the net movement of water molecules from a region of high water concentration to a region of lower water concentration through a partially permeable membrane'. In my experiment the process of osmosis will be due to the concentration of sucrose inside the cell compared to outside. Therefore if there is a higher concentration of sucrose molecules outside the cell then the net movement of water molecules will be out of the cell and similarly if there is a higher concentration of sucrose molecules inside the cell then the net movement of water molecules will be into the cell....   [tags: Papers] 2785 words
