Cation Effect on Slow Release from Alginate Beads: A Fluorescence Study
(Springer/Plenum Publishers, 2014)In this study spherical alginate beads containing pyranine (P-y) as a fluorescence probe were prepared by ionotropic gelation of a sodium alginate solution. The steady state fluorescence technique was used to study pyranine ... -
Certification of almost global phase synchronization of all-to-all coupled phase oscillators
(Pergamon-Elsevier Science Ltd, 2023)Coupled oscillators may exhibit almost global phase synchronization, namely their phases tend to asymp-totically overlap for almost all initial conditions. We consider certification of this property using Rantzer's dual ... -
Cervical Radiculopathy caused by vertebral artery loop formation - Multislice computed tomography angiography findings
(Lippincott Williams & Wilkins, 2005)Vertebral artery tortuosity and loop formation are rare causes of cervical radiculopathy. The criterion standard for the detection of vertebral artery loop formation is digital subtraction angiography. Computed tomography ... -
Cervical spine injuries in children
(2004)Cervical spine injuries in children and adolescents are rare. Common mechanisms include motor vehicle accidents, sports injuries, fall from height, and gunshot injuries. Cervical spine injuries are classified by Allen and ... -
Challenges of Teaching in a Different Culture: An Auto-Ethnographic Study
(Cognizant Communication Corp, 2021)Teaching in a different culture and environment is always a challenging issue. This may last from a few months to a few years, depending on the consequences of personal characteristics and environmental situations. Based ... -
Challenges of the Filter Paper Suction Measurements in Geosynthetic Clay Liners: Effects of Method, Time, Capillarity, and Hysteresis
(Amer Soc Testing Materials, 2022)Time and method dependencies, lack of sufficient capillary connections, and wetting-drying hysteresis may cause inaccurate results from filter paper tests (FPTs) when used for suction measurements of geosynthetic clay ... -
