Motor neurons are highly polarized cells,with long axons that extend to more than 1 m in the adult human.The axons further arborize into a specialized synaptic compartment,the motor unit,containing up to 2000 neuromuscular junctions(NMJs).While the size of other neuronal synapses can be up to 1μm,the NMJ is much larger and can reach 10–30μm(Jones et al.,2017).The vast size of the motor unit requires motor neurons to evolutionally adapt and supply this distal portion with a sufficient amount of ATP,as well as to replenish the axonal protein pool in order to maintain their synapses. 展开更多

This study explores the aesthetic dimensions of Kwame Nkrumah's cultural policies in the creation of Ghana's Presidential Seats and the State Sword. The study is an Art Historical research situated within the qualitative research paradigm. It had a population of a defmed class of cultural policy makers, art historians, traditional rulers, nationalists, visual artists and Ghanaians resident both in and outside Ghana. The study examined how the creation of Ghana's Presidential Seats and the State Sword were influenced by Kwame Nkrumah's cultural policies and the cultural significance of the aesthetic interplay of ethnic insignias used in capturing the Ghanaian concept of Political authority. The study revealed that, Nkrumah recognised the cultural art forms and elements of ethnic Ghana as assets for national development. In line with his policy of building the Nation State of Ghana, he used ethnic cultural art forms and elements. At independence, Nkrumah commissioned some visual artist to create some artistic pieces (politico-cultural artefacts) for the Ghanaian political authority with inspiration or based on what pertains in the traditional authority (Chieftaincy) of Ghana. Politico-cultural artefacts as used in this study refer to the artefacts produced based on the cultural concepts of the ethnic states for the use of the political authority of the Republic of Ghana. Among these artistic pieces are the three Presidential Seats, The State Sword, The President's Personal Standard Pole and the State Mace. 展开更多

Over 10%of English Restoration drama engaged its audience through plays that were translated from or imitated the Spanish capa y espada form of theatre.English plays modeled on this form used Spanish locations and a constructed and rigid idea of honor as a proxy for English society.While dialogue was still important,it performed physical action of this form,including frequent use of breeches roles and female characters sword fighting,allowed for different and effective critiques and models of social behavior for women in England.Particularly important were concerns about women’s behavior and status in English society,and the presence of the actress for the first time on English stages heightened the effectiveness of these plays as an instrument of social discussion. 展开更多

Some critics even call his nar- rative system as Jin yong Narratology. In his novels, there are a large number of unforgettable characters especially female characters that are warmly received by readers. What’s more, his methods of characterization in his novels can be said to be classic and sole. And that is the reason that characters in his novels make deep impressions on readers. Thus, this thesis aims to analyze a special female character Zhou Zhiruo in The Heaven Sword and the Dragon Sabre from the aspects of character and characterization in Narrotology. Zhou Zhiruo is a round character seldom seen in Chinese novel. Through studying on image features and reasons of her image features, Jin yong’s martial arts novels’ charm has been greatly displayed. It is hoped that this thesis can provide some useful information for researchers or persons who take interest in Jin yong 展开更多

This sword was a popular weapon with warriors in ancient China, but it was also worn by gentlemen as status symbol. It was first used at the end of the Shang Dynasty (21st Century B.C.-16th Century B.C.) and became popular during the Spring and Autumn period (770 B.C.-476 B.C.) and the Warring States period (475 B.C.-221 B.C. ). The best examples of this sword at that time were made in the Wu State and the Yue State. The sword was used by Gou Jian, King of the Yue State during the Warring States period. It was discovered in 1965, and is considered the best example of its kind. Shown here is a 展开更多
