In agriculture, the increased usage of sheep with long-fibred wool allowed a stronger thread to be spun. In addition, the spinning wheel replaced the traditional distaff for spinning wool, tripling production.[AI] A less technological refinement that still greatly affected daily life was the use of buttons as closures for garments, which allowed for better fitting without having to lace clothing on the wearer. Windmills were refined with the creation of the tower mill, allowing the upper part of the windmill to be spun around to face the direction from which the wind was blowing. The blast furnace appeared around 1350 in Sweden, increasing the quantity of iron produced and improving its quality. The first patent law in 1447 in Venice protected the rights of inventors to their inventions.
Where did patent law originate?

Wang, Strkalj et al. (2003) examined the use of race as a biological concept in research papers published in China's only biological anthropology journal, Acta Anthropologica Sinica. The study showed that the race concept was widely used among Chinese anthropologists. In a 2007 review paper, Strkalj suggested that the stark contrast of the racial approach between the United States and China was due to the fact that race is a factor for social cohesion among the ethnically diverse people of China, whereas "race" is a very sensitive issue in America and the racial approach is considered to undermine social cohesion - with the result that in the socio-political context of US academics scientists are encouraged not to use racial categories, whereas in China they are encouraged to use them.
Who is the race concept widely used by?
Chinese anthropologists

Witnesses believe that a "little flock" go to heaven, but that the hope for life after death for the majority of "other sheep" involves being resurrected by God to a cleansed earth after Armageddon. They interpret Revelation 14:15 to mean that the number of Christians going to heaven is limited to exactly 144,000, who will rule with Jesus as kings and priests over earth. Jehovah's Witnesses teach that only they meet scriptural requirements for surviving Armageddon, but that God is the final judge. During Christ's millennial reign, most people who died prior to Armageddon will be resurrected with the prospect of living forever; they will be taught the proper way to worship God to prepare them for their final test at the end of the millennium.
Who is the final Judge of whether Jehovah Witnesses get to survive Armageddon?
God
