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]

AM Radio Design - Objective: The objective of this lab is to design and AM Radio. Introduction: Am radio uses Amplitude Modulation (AM), which works by varying the strength of the transmitted signal in relation to the information being sent. When you tune into an AM radio station, for example 1560 on the AM dial the transmitter’s sine wave is transmitted the data at 1560,000 hertz. What this number essentially means is that the sine wave repeats every 1560,000 times per second. The data is modulated onto the carrier wave by changing the amplitude of this sine wave....   [tags: Engineering Radio Design ] 1780 words

Left Ventricular Systolic Dysfunction - Left Ventricular Systolic Dysfunction (LVSD, but commonly referred to as heart failure) is a chronic, progressive cardiac syndrome in which a damaged heart fails to beat efficiently and deliver enough blood to meet the body's needs. Although coronary heart disease (CHD) is the most common cause, for example, myocardial infarction, and many of the conditions are intertwined, there are several other causes of heart failure including cardiomyopathies, hypertension and valve disease. Cardiomyopathies can be caused by genetic disorders/defects, viral illness, some endocrine conditions, autoimmune diseases, and excessive use of alcohol and drugs....   [tags: Health]

Microeconomics Assignment - (A) Methamphetamine is a highly addictive drug, hence there is a high necessity associated with it, which would mean that for users of the drug, demand would be inelastic. P is a reputed necessity, because it is a good which isn’t essential for survival, but many users simply think they have to have it. Because those who use P generally have a strong addiction and dependence to P, an increase in price, caused by reduced supply from increased seizures of precursors used in the manufacture of the drug, such as pseudoephedrine, would most likely result in a less than proportional change in quantity demanded....   [tags: Economics] 1162 words

Evaluate proposals for reducing environmental air pollution by energy - Evaluate proposals for reducing environmental air pollution by energy taxation and emissions trading. Pollution is created as a by-product of output in most industries. It can be described as an external cost to the economy as its existence causes a loss of welfare to the population as a whole, and, in a free market, this loss of welfare will generally go uncompensated. However, that does not mean that the optimal level of pollution is zero, contrary to the environmentalist presumption, as this would mean that economic activity would have to be zero and this is illogical....   [tags: Economics] 1984 words
