Abstract. The characterization of flexible joints robotic underactuated fingers allows the investigation finger flexion trajectories using a tendon-driven actuation. In this paper, TPU 3D printed used in fingers, is experimentally and numerically performed. Since mechanical properties materials are uncertain, research helps to define characteristics terms stiffness. role stiffness for control f...

background: sellick's maneuver (cricoid pressure) may make laryngoscopic view and tracheal intubation more difficult. this study compared the different techniques of cricoid pressure (cp) regarding to the laryngoscopic view and time to intubation. methods: in142 anesthetized patients, 4 types of cp was randomly applied; a) one-handed cp using thumb, index and middle fingers, b) one-handed cp us...

We study the existence and structure of steady-state ngers in two-dimensional solidiication, when the surface energy has a crystalline anisotropy so that the energy-minimizing Wull shape and hence the solid-liquid interface are polygons, and in the one-sided quasi-static limit so that the diiusion eld satisses Laplace's equation in the liquid. In a channel of nite width, this problem is the cry...

We investigated fingers as a potential source of nickel transfer to the face in patients with allergic contact dermatitis to nickel and a history of facial dermatitis. Samples were collected from the fingers and cheeks of volunteers using the stripping method with standard adhesive tape, and nickel levels were quantified using mass spectrometry. Fingers and cheeks of individuals who had handled...

Finger agnosia has been described as an inability to explicitly individuate between the fingers, which is possibly due to fused neural representations of these fingers. Hence, are patients with finger agnosia unable to keep tactile information perceived over several fingers separate? Here, we tested a finger agnosic patient (GO) on two tasks that measured the ability to keep tactile information...

When ice forms on lakes, dissolved salts are rejected, which can lead to under-ice salt-finger formation. We performed a series of laboratory experiments visualize these fingers. While we detected salt-fingers in our camera recordings, the signal fingers is nearly absent temperature record. quantify velocity salt plumes and measure bottom salinity increase from Further, estimate that often dist...

objectives: the objective was to determine the results of early active controlled motion in the patients rehabilitated by our new protocol. methods: 91 fingers in 64 patients with flexor tendon repair in all zones were enrolled in a single group (quasi-experimental) clinical trial. 58 fingers in 43 patients were assessed at least three months postoperatively. outcomes were defined using the ‘wh...
