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?
The Shard was developed by Sellar Property Group on behalf of LBQ Ltd, and is jointly owned by Sellar Property and the State of Qatar.n 2014, The Shard claimed first place at the Emporis Skyscraper Awards, recognising buildings over 100 metres completed in the previous twelve months. The Emporis judges hailed the building as a skyscraper that is recognized immediately and which is already considered London's new emblem.
