BACKGROUND There are multiple techniques for face-mask (FM) ventilation. To our knowledge, the one-handed vs. two-handed C-E technique has been compared in children and adults, but no studies have compared the various two-handed methods. OBJECTIVE To compare the effectiveness of mask seal using three different FM techniques on a model intended to simulate difficult FM ventilation and measure ...

A classical continuum theory corresponding to Barrett and Crane’s model of Euclidean quantum gravity is presented. The fields in this classical theory are those of SO(4) BF theory, a simple topological theory of an so(4) valued 2-form field, B μν , and an so(4) connection. The left handed (self-dual) and right handed (anti-self-dual) components of B define a left handed and a, generally distinc...

Unlike the phonological loop in spoken language monitoring, sign language users' own production provides mostly proprioceptive feedback and only minimal visual feedback. Here we investigate whether sign production influences sign comprehension by exploiting hand dominance in a picture-sign matching task performed by left-handed signers and right-handed signers. Should all signers perform better...

Background: Dysgraphia as a problem with handwriting, affects student’s performance in school activities and participation. The purpose of the study was to compare dexterity and two-point discrimination of the hand between learning disabled students with dysgraphia and healthy students.   Methods: Forty-three students with developmental dysgraphia and 55 normal students in grade t...
