The usual Hadamard principal value is defined asAbout properties and applications of singular integals of high order were investigated by many authors([1],[2],[3] etc. ) In 1987, the concepts of Hadamard principal value at one-side for singular integralsof high order and the rules of their differentiation are introduced [4]. In this paper we established the rulesof substitution of variable for one-sided Hadamard principal value of singular integrals of high order, andthen, we gave some applications in evaluation of real definite integrals.展开更多

Developments in the diagnosis and management of rare diseases have been relatively slow due to a lack of sufficient profit motivation and market to attract research by companies. However, due to the attention of government and society as well as economic development, rare diseases have been gradually become an increasing concern. As several dental-craniofacial manifestations are associated with rare diseases,we summarize them in this study to help dentists and oral maxillofacial surgeons provide an early diagnosis and subsequent management for patients with these rare diseases.展开更多

Efficacy and safety information were assessed at one year follow-up. The relapse rate was similar in both groups after 12 months followed up (7% and 5%). The withdraw rate was significant lower in CM group compared with CAU group (10% and 36%). <strong>Results</strong>: There is no significant difference in PANSS, PSP and SSMI score between 2 groups at each visit. Between endpoint and baseline, there is a significant improvement on PANSS negative score and PSP in patients treated with CM, while CAU group was not significantly changed. <strong>Conclusions</strong>: There is a possible effectiveness of CM group of improving negative symptoms and social function in schizophrenia clients.展开更多
