Problem: Although dissertations on clothing and its function appear from the 19th century as colonising countries dealt with new environments, concerted scientific research into psycho-social, physiological and other functions of clothing (e.g. protective, cartage) occurred in the first half of the 20th century, with publications such as J. C. Flügel's Psychology of Clothes in 1930, and Newburgh's seminal Physiology of Heat Regulation and The Science of Clothing in 1949. By 1968, the field of environmental physiology had advanced and expanded significantly, but the science of clothing in relation to environmental physiology had changed little. While considerable research has since occurred and the knowledge-base has grown significantly, the main concepts remain unchanged, and indeed Newburgh's book is still cited by contemporary authors, including those attempting to develop thermoregulatory models of clothing development.
What have remained unchanged while the knowledge has grown?
The answer is the following: the main concepts

Problem: In 1984, he was appointed as a member of the Order of the Companions of Honour (CH) by Queen Elizabeth II of the United Kingdom on the advice of the British Prime Minister Margaret Thatcher for his "services to the study of economics". Hayek had hoped to receive a baronetcy, and after he was awarded the CH he sent a letter to his friends requesting that he be called the English version of Friedrich (Frederick) from now on. After his 20 min audience with the Queen, he was "absolutely besotted" with her according to his daughter-in-law, Esca Hayek. Hayek said a year later that he was "amazed by her. That ease and skill, as if she'd known me all my life." The audience with the Queen was followed by a dinner with family and friends at the Institute of Economic Affairs. When, later that evening, Hayek was dropped off at the Reform Club, he commented: "I've just had the happiest day of my life."
How did Hayek wish to be referred to after his 1984 award?
The answer is the following: Frederick

Problem: There are seven suburbicarian sees: Ostia, Albano, Porto and Santa Rufina, Palestrina, Sabina and Mentana, Frascati and Velletri. Velletri was united with Ostia from 1150 until 1914, when Pope Pius X separated them again, but decreed that whatever cardinal bishop became Dean of the College of Cardinals would keep the suburbicarian see he already held, adding to it that of Ostia, with the result that there continued to be only six cardinal bishops.
What are the seven sees?
The answer is the following: Ostia, Albano, Porto and Santa Rufina, Palestrina, Sabina and Mentana, Frascati and Velletri

Problem: In 1578 king Stefan Batory created the Crown Tribunal in order to reduce the enormous pressure on the Royal Court. This placed much of the monarch's juridical power in the hands of the elected szlachta deputies, further strengthening the nobility class. In 1581 the Crown Tribunal was joined by a counterpart in Lithuania, the Lithuanian Tribunal.
The crown tribunal was created when?
The answer is the following:
1578
