Assessing thinking skills in free-response exam problems: Pandemic online and in-person

Physical Review Physics Education Research, 2023
We present an analysis of students’ thinking skills as evidenced by free-response exam problems during the Covid-19 pandemic. We compare two inquiry-based, laboratory-based classical mechanics courses, one taught online and one taught in person during ...

Two New Theories for the Current Charge Relativity and the Electric Origin of the Magnetic Force Between Two Filamentary Current Elements

IEEE Access, 2016
This paper presents two new theories and a new current representation to explain the magnetic force between two filamentary current elements as a result of electric force interactions between current charges. The first theory states that a current has an

Electricity and Magnetism Electric and Magnetic Circuits A Text-book of Electrical Machinery [PDF]

Nature, 1904
THE best method of training electrical engineers will probably remain a subject of discussion so long as the profession continues to be a profitable one. Whether recourse should be had to the factory or to the technical college; whether a combination of these two is desirable or necessary, and if so, in what manner they should be combined; and whether ...

Spinal Cord Infarction Versus Idiopathic Transverse Myelitis: Clinical, Radiological, and Functional Insights From a Retrospective Cohort Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Spinal cord infarction (SCI) is a rare but devastating myelopathy, characterized by a high disability rate and an unfavorable prognosis. It has often been underdiagnosed and misdiagnosed as idiopathic transverse myelitis (ITM). This study aimed to describe the clinical features, radiological biomarkers, treatments, and functional ...
