One way of monitoring physical activity intensity is to determine whether a person's pulse or heart rate is within the target zone during physical activity. For moderate-intensity physical activity, a person's target heart rate should be 50 to 70% of his or her maximum heart rate.This maximum rate is based on the person's age.An estimate of a person's maximum age-related heart rate can be obtained by subtracting the person's age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 - 50 years = 170 beats per minute (bpm).his maximum rate is based on the person's age.

MongoDB - Sharding. Sharding is the process of storing data records across multiple machines and it is MongoDB's approach to meeting the demands of data growth. As the size of the data increases, a single machine may not be sufficient to store the data nor provide an acceptable read and write throughput. Sharding solves the problem with horizontal scaling. With sharding, you add more machines to support data growth and the demands of read and write operations. Why Sharding?
SHARIA (ISLAMIC LAW). Shari'a is an Arabic word meaning âpathâ or âway.â Today the term is used most commonly to mean âIslamic law,â the detailed system of religious law developed by Muslim scholars in the first three centuries of Islam and still in force among fundamentalists today.
