      Acanthamoeba castellanii can cause granulomatous amoebic encephalitis and Acanthamoeba keratitis. Currently, no single drug has been developed to effectively treat infections caused by Acanthamoeba. Recent studies have ...
    • Modeling and simulation of hypothermia effects on cardiac electrical dynamics 

      Belhamadia, Youssef; Grenier, Justin (Public Library of Science, 2019)
      Previous experimental evidence has shown the effect of temperature on the action potential duration (APD). It has also been demonstrated that regional cooling of the heart can prolong the APD and promote the termination ...
    • Muslim Women's Evolving Leadership Roles: A Case Study of Women Leaders in an Immigrant Muslim Community in Post-9/11 America 

      Wang, Yuting (Sage, 2017)
      Based on three years of ethnographic fieldwork in a multi-ethnic immigrant Muslim congregation in a Midwestern city in the United States, this paper scrutinizes the intricate process through which women uses traditional ...
    • A new characterization of periodic oscillations in periodic difference equations 

      Al-Salman, Ahmad; Al-Sharawi, Ziyad (Elsevier, 2011-11)
      In this paper, we characterize periodic solutions of p-periodic difference equations. We classify the periods into multiples of p and nonmultiples of p. We show that the elements of the set of multiples of p follow the ...
    • Novel Azoles as Antiparasitic Remedies against Brain-Eating Amoebae
