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 ... -
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 ... -
