Context and question: Due to the work nature of airline pilots, who often cross several timezones and regions of sunlight and darkness in one day, and spend many hours awake both day and night, they are often unable to maintain sleep patterns that correspond to the natural human circadian rhythm; this situation can easily lead to fatigue. The NTSB cites this as contributing to many accidents[unreliable medical source?]  and has conducted several research studies in order to find methods of combating fatigue in pilots.
what does a natural circadian rhythem lead to?

Context and question: The Gurkhas, a martial tribe, came to power in Nepal in the year 1768. They consolidated their military power and began to expand their territory. Gradually, the Gorkhas annexed Sirmour and Shimla. With the leadership of Amar Singh Thapa, Gorkhas laid siege to Kangra. They managed to defeat Sansar Chand Katoch, the ruler of Kangra, in 1806 with the help of many provincial chiefs. However, Gurkhas could not capture Kangra fort which came under Maharaja Ranjeet Singh in 1809. After the defeat, the Gurkhas began to expand towards the south of the state. However, Raja Ram Singh, Raja of Siba State managed to capture the fort of Siba from the remnants of Lahore Darbar in Samvat 1846, during the First Anglo-Sikh War. They came into direct conflict with the British along the tarai belt after which the British expelled them from the provinces of the Satluj. The British gradually emerged as the paramount power. In the revolt of 1857, or first Indian war of independence, arising from a number of grievances against the British, the people of the hill states were not as politically active as were those in other parts of the country. They and their rulers, with the exception of Bushahr, remained more or less inactive. Some, including the rulers of Chamba, Bilaspur, Bhagal and Dhami, rendered help to the British government during the revolt.

Context and question: In 2006, FIG introduced a new points system for Artistic gymnastics in which scores are no longer limited to 10 points. The system is used in the US for elite level competition. Unlike the old code of points, there are two separate scores, an execution score and a difficulty score. In the previous system, the "execution score" was the only score. It was and still is out of 10.00. During the gymnast's performance, the judges deduct this score only. A fall, on or off the event, is a 1.00 deduction, in elite level gymnastics. The introduction of the difficulty score is a significant change. The gymnast's difficulty score is based on what elements they perform and is subject to change if they do not perform or complete all the skills, or they do not connect a skill meant to be connected to another. Connection bonuses are the most common deduction from a difficulty score, as it can be difficult to connect multiple flight elements. It is very hard to connect skills if the first skill is not performed correctly. The new code of points allows the gymnasts to gain higher scores based on the difficulty of the skills they perform as well as their execution. There is no maximum score for difficulty, as it can keep increasing as the difficulty of the skills increase.
What is the minimum gymnastics score?
