Take-off analysis of the Olympic ski jumping competition (HS-106m).
2007
Abstract The take-off phase (approximately 6 m) of the jumps of all athletes participating in the individual HS-106 m hill ski jumping competition at the Torino Olympics was filmed with two high-speed cameras. The high altitude of the Pragelato ski jumping venue (1600 m) and slight tail wind in the final jumping round were expected to affect the results of this competition. The most significant correlation with the length of the jump was found in the in-run velocity ( r =0.628, p n =50). This was a surprise in Olympic level ski jumping, and suggests that good jumpers simply had smaller friction between their skis and the in-run tracks and/or the aerodynamic quality of their in-run position …
Re-ventriculostomy for treatment of obstructive hydrocephalus in cases of stoma dysfunction.
2002
In this article, 12 re-ventriculostomies in the treatment for obstructive hydrocephalus are described. The etiology of the hydrocephalus was a benign aqueductal stenosis in 9 patients, a tumor around the aqueduct in 2 patients and intraventricular bleeding in one patient. In all cases the initial ventriculostomy was successful, but after a time interval of 2 weeks to 6 years the patients developed similar clinical symptoms as preoperatively. In all except one case the radiological findings spoke in favour of stoma closure. Intraoperatively the stoma was completely closed in 9 patients and in 3 patients a subtotal closure was observed. In all cases a re-ventriculostomy was performed bluntly …
Inhibitory effect of A10 dopaminergic neurons of the ventral tegmental area on the orienting response evoked by acoustic stimulation in the cat.
1998
Abstract The effect of bilateral electric stimulation of A10 dopaminergic neurons of the ventral tegmental area (80–300 μA, 20–50 Hz, 0.1–0.5 ms, 2 s duration) on latency and duration of the orienting response, evoked by acoustic stimuli (4500–8000 Hz, 2 s), was studied in the cat. A10 neuron stimulation, simultaneous with the acoustic one, was performed with threshold parameters inducing minimal behavioral signs (head searching movement, sniffing, increase in alertness). By means of a videoanalysis system, a statistically significant increase, both of latency and duration of the response, was observed. The possible role of dopamine was studied administrating sulpiride (20 mg/kg IP), a dopa…
Is It Possible to Educate, Intervene or “Cure” Autism Spectrum Disorder? A Content Analysis of YouTube Videos
2021
YouTube es uno de los sitios web más conocidos y de mayor acceso en todo el mundo, por lo que tiene un gran potencial pedagógico. No obstante, la calidad y la veracidad de algunos videos de YouTube son cuestionables. Las dudas sobre la confiabilidad del contenido fáctico es un factor controvertido que debe tenerse en cuenta, especialmente cuando se abordan cuestiones de salud pública. Por ello, el principal objetivo de este trabajo es analizar el contenido de los vídeos en español más vistos en YouTube relacionados con el trastorno del espectro autista (TEA). Para la realización de esta investigación se utilizaron los términos "autismo Y educación", "autismo Y intervención" y "autismo Y cur…
Analysis of high-frequency rotational angioplasty-induced echo contrast.
1991
During high-frequency rotational angioplasty (HFRA), myocardial contrast enhancement (echo contrast) was observed by means of two-dimensional echocardiography. In order to evaluate the echo contrast produced by HFRA, an in vitro experimental model was built using a cylinder with the HFRA catheter scanned in a water bath. The cylinder was filled with blood, mineral water, and distilled water. With a 2.5-MHz transducer, echograms were recorded and analyzed by video intensitometer, and the maximum intensity IUmax and persistence time P were calculated. Rotation frequencies of 20,000-200,000 rpm with 2.0--mm burrs and times of 10 s were tested. In another model, hyperbaric conditions for the sa…
Training program for transanal endoscopic microsurgery.
1988
Televised endoscopy and the concept of the “assisted” endoscopic operation is of great help in teaching surgical endoscopic techniques. The use of training dummies provides a new method of training manual dexterity and surgical skills in special courses or in surgical skill laboratories. We have developed a training system for transanal endoscopic microsurgery. Operations with our technique were performed on 116 patients. Like other microsurgical techniques, our method requires a special introduction and intensive training. This paper presents our multistage, video-supported training course for teaching transanal endoscopic microsurgery. The one-day training session is divided into four ste…
