    • Omani Teachers' Attitude Toward Classroom Research 

      Al Farsi, Basim Ahmed (2006-06)
      Although there has been a lot of research done to investigate teachers' attitudes toward classroom research, there has been little research, if any, in the Gulf area, and especially in Oman. In fact, classroom research is ...
    • On 1-absorbing primary ideals of commutative rings 

      Badawi, Ayman; Celikel, Ece Yetkin (World Scientific, 2019-04-30)
      Let R be a commutative ring with nonzero identity. In this paper, we introduce the concept of 1-absorbing primary ideals in commutative rings. A proper ideal I of R is called a 1-absorbing primary ideal of R if whenever ...
    • On Efficient Channel Modeling for Video Transmission over Cognitive Radio Networks

      Anderson, David F.; Badawi, Ayman (Taylor and Francis, 2020-08-14)
    • On phi-Dedekind rings and phi-Krull rings 

      Badawi, Ayman; Anderson, David F. (University of Houston, 2005)
      The purpose of this paper is to introduce two new classes of rings that are closely related to the classes of Dedekind domains and Krull domains. Let H = {R | R is a commutative ring with 1 and Nil(R) is a divided prime ...
    • On phi-Mori rings 

      Badawi, Ayman; Lucas, Thomas G. (University of Houston, 2006)
      A commutative ring R is said to be a phi-ring if its nilradical Nil(R) is both prime and comparable with each principal ideal. The name is derived from the natural map phi from the total quotient ring T(R) to R localized ...
