<span lang="EN-US">Since the COVID-19 pandemic, automated liquid dispensers have been increasingly developed to assist transmission prevention. However, data availability of automatic dispenser mechanism's technical characteristics is not yet widely available. This causes frequent over or under design in its development. Therefore, we specifically measure push and pull forces engineering ...

A major restructuring of the Sophomore level “Introduction to Design Theory” course at the United States Air Force Academy has recently been completed. The most significant aspect of this restructuring is the addition of a redesign component to the course. In order to gauge the effectiveness of this restructuring, a questionnaire was developed to determine student rating of the course content l...

objective(s): the purpose of the present study was to prepare and to evaluate a novel niosome as transdermal drug delivery system for propranolol hydrochloride and to compare the in vitro efficiency of niosome by either thin film hydration or hand shaking method. materials and methods: niosomes were prepared by thin film hydration (tfh) or hand shaking (hs) method. propranolol niosomes were pre...

Repetitive, high-force pinch grip exertions are common in many occupational activities. The goal of the current study was to quantify the relationship between lateral pinch grip span (distance between thumb and index finger) and lateral pinch grip strength. An experiment was conducted in which 40 participants performed maximal lateral pinch grip exertions at 11 levels of grip span distances (0,...

Principles of saccadic eye movement control in the real world have been derived by the study of self-paced well-known tasks such as sandwich or tea making. Little is known whether these principles generalize to high-speed sensorimotor tasks and how they are affected by learning and automatization. In the present study, right-handers practiced the speed-stacking task in 14 consecutive daily trai...

Eye movements and manual keypresses of one high-skilled typist were analyzed to determine eye-hand span, viewing time, and typing time for word and letter units. The results revealed a relatively small eye-hand span of 2.4 character spaces. Fixation time and typing time were positively correlated when word and letter units were analyzed. However, the correlation accounted for 79% of the variabi...

pachydermodactyly is a rare and benign disease that may be idiopathic, genetic, acquired as a response to repetitive trauma, or associated with several other acquired conditions often pushing the health caregiver to do a bunch of costly lab tests and diagnostic workups to rule out other entities. all health care givers must be aware about this disease for reassure the patients and cut unnecessa...
