The current paper studies the pressure generated between two parallel grooved surfaces, as occurs in oil control ring internal combustion engines. It is shown that depends significantly on position of groove intersections, and thus a single calculation cannot describe during full passage over pattern. Furthermore, it introduction distance variation reduces variation, but does not affect mean ge...

Water droplets impinging on micro-grooved polydimethylsiloxane surfaces were studied. Depending the impact velocity and surface roughness, different phenomena such as no bouncing, complete rebound (CR), bouncing occurring with droplet breakup (BDB), partial rebound, sticky state observed. The lower limit of for can be determined by balancing kinetic energy barrier due to contact angle hysteresi...

Electrophysiological studies on female An. gambiae s.s. mosquitoes revealed a receptor neuron within a subpopulation of the antennal grooved-peg sensilla sensitive to the odour of incubated sweat, but not responding to fresh sweat. This receptor neuron was sensitive to ammonia as well, a sweat-borne component which attracts female An. gambiae in a windtunnel bioassay. Neurons innervating a diff...

BACKGROUND The practice of anesthesia requires good awareness, parallel decision-making and fine motor skills. The duration of working hours of anesthesiology residents is often more than 12 hours. OBJECTIVES This study aimed to measure cognitive and psychomotor functions of anesthesiology residents after 12 working hours. PATIENTS AND METHODS This was an observational study on anesthesiolo...
