The glass pH sensor is an example of anionselectiveelectrode (ISE). This system consists of the ISE reacting on a special ion type, in this case the hydrogen ion, and a reference electrode that are jointly immersed in the sample to be measured. ...

With this type of annuity the insurance company is guaranteeing payments for as long as one or both of the annuitants are living. The annuity payments would stop on the passing of the (last) annuitant. As an aside, the age of the annuitant(s) is a key factor in determining the monthly...
In potentiometric titration, the concentration-dependent potential (mV) of a solution is measured against a reference potential. In practice, potentiometric titration bears similarity to a redox reaction. However, potential is measured across the analyte — typically an electrolyte solution — using refer...
Plant height (PH) is a critical component of plant architecture. The ideal height is sought after for natural beauty and better growth. The pursuit of maximizing the overall crop yield and harvest has resulted in “ideal-type breeding”, especially in cereal crops. One of the greatest successes...
RAM is typically measured in gigabytes (GB). Common RAM sizes include 4GB, 8GB, 16GB, 32GB, and 64GB. In some high-end systems, you might even see capacities of 128GB or more. What’s the difference between RAM and storage? RAM is volatile, short-term memory used for quick data acc...
Many procurement groups monitor the number of vendors in their supplier networks and periodically remove little-used suppliers to increase efficiency. Supplier defect rate: An important measure of supplier quality, this is usually measured as the number of defective parts divided by the total number ...
Aptitude: A construct that is measured which is innate, usually in a cognitive context. For example, logical reasoning ability. Biserial Correlation: A classical index of item discrimination, highly similar to the more commonly used point-biserial. The biserial correlation assumes that the item score...
How is the rate of reaction measured for an enzyme? What impact do enzyme and substrate concentration have on the rate of enzyme activity? What factors affect enzyme activity? What is the optimum temperature of the enzyme Bromelain? What affects the activity of Brom...
the likelihood of default. A PD is typically measured by assessing past-due loans. It is calculated by running a migration analysis of similarly rated loans. The calculation is for a specific time frame and measures the percentage of loans that default. The PD is then assigned to the risk ...
