A4 paper is the most widely used paper type that is produced by using wood-free writing & printing paper with the least amount of wood in its structure. A4 size paper is produced by cutting large and long rolls in width and length directions. The construction of this machine is not made in Turkey. In this study, a prototype designed for a paper cutting machine is presented. For this prototype, step motors are used that can be set at different speeds and polyamide rollers are used to transfer the paper from one line to another without tearing. Some problems that is encountered for the designed paper cutting machine are discussed and some analyses are made to solve these problems. It has been found that the misalignment of the shaft axes during the transfer of the paper and the not suitable construction of the shafts causes the non-uniform cutting of the paper. It is also observed that the speed of the motor must the paper adjusted at an appropriate rate, to avoid the stretch and break of paper. [ABSTRACT FROM AUTHOR]

While hundreds of scientific and artistic studies have been undertaken about Yunus Emre, one of the most important figures of Turkish culture and literature, only a few bibliographic studies have been chosen to compile these studies. Moreover, some of the studies are quite narrow in scope. There has been a rapid increase in the literature about Yunus Emre since the first comprehensive bibliographic study covering the period up to 1991. However, it remains a major shortcoming in the field that a comprehensive bibliography study has not been conducted. In this paper, which was written on the occasion of Yunus Emre Year, the author aimed to make a bibliographical master-text of the literature about Yunus Emre from 1991 to 2021. The bibliographic tags of the books, theses, articles, symposiums, and papers published between these years are given. [ABSTRACT FROM AUTHOR]
