Abstract: Los huesos parietales habitualmente presentan peque os forámenes, estos en número de dos se encuentran situados próximo de la unión de la sutura sagital con la lambdoidea. éstos forámenes permiten que venas emisarias drenen en el seno longitudinal superior a venas occipitales y, algunas veces, transmite una peque a rama de la arteria occipital. Se efectuó un estudio anatómico en 39 calotas, en buen estado de conservación, de individuos adultos, del museo de la Unidad de Anatomía, Universidad de La Frontera, Chile. Se registraron los siguientes datos: presencia del foramen parietal, distancia desde el lambda al foramen parietal y desde el foramen parietal a la sutura sagital, diámetro del foramen parietal. El 58,9% de las calotas presentaban cada uno de los huesos parietales un foramen; el 25,6% presentaba un foramen en un parietal no existiendo en el hueso contralateral; y el 15,3% no presentaba foramen parietal. La distancia promedio del lambda al foramen parietal fue de 33,25 mm; la distancia de la sutura sagital al foramen parietal fue en promedio de 6,29mm; el promedio del diámetro máximo del foramen parietal fue de 2,65mm y el mínimo de 0,37mm. Estos datos anatómicos del foramen parietal aportan nuevos antecedentes para futuros estudios. The bone parietal foramina usually minor, in these two numbers are located near the junction of the sagittal suture with lambdoidea. These foramina allow emissary veins draining into the superior longitudinal sinus in the occipital veins, and sometimes sends a small branch of the occipital artery. Anatomical studies in 39 cranium, well-preserved, adult, of the Anatomy Museum of the Universidad de La Frontera, Chile was realized. Recorded the following data: presence of the parietal foramen, the distance from the lambda and the parietal foramen parietal foramen to the sagittal suture and diameter of the parietal foramen. The 58.9% of the cranium presented each of the parietal bone foramen, 25.6% had a parietal foramen in a bone in the absence of contralateral and 15.3% had no parietal foramen. The average distance from lambda to parietal foramen was 33.25 mm, the distance from the sagittal suture to the parietal foramen averaged 6.29 mm, the average maximum diameter of the parietal foramen was 2.65 mm and a minimum of 0 , 37mm. These anatomical data provide new parietal foramen of the background for future studies.
Stimulus affective valence reverses spatial compatibility effect

Abstract: In spatial compatibility tasks, the Reaction Time to right-side stimuli is shorter for right key responses (compatible condition) than for left key responses (incompatible condition) and vice-versa for left-side stimuli. Similar results have been found when the stimulus location is not relevant for response selection, such as in the Simon task. The Simon effect is the difference between the reaction times for non-corresponding and corresponding conditions. The Simon effect and its variants may be modulated by using emotional stimuli. However, until now, no work has studied how the affective valence of a stimulus infuences spatial compatibility effects along the horizontal dimension. The present study investigated this issue by using small lateralized fgures of soccer team players as stimuli. In the experiment, a compatible or incompatible response was chosen according to the team shirt. In one block, for the Favorite team, the volunteers had to press the key on the same side as the stimulus hemifeld but the opposite-side key for the Rival team. In the other block, a reverse code had to be used. Fourteen right-handed volunteers were tested. Mean reaction times were subjected to analysis of variance with the following variables: Preference (Favorite/Rival), Hemifeld (Left/Right), and Response Key (Left/Right). A three-way interaction was found (F1,13 = 6.60, p = .023), showing that the spatial compatibility effects depended on Preference. The Favorite team player elicited the usual spatial compatibility pattern, but for the Rival team player, the reverse effect was found, with incompatible responses being faster than compatible responses. We propose that this modulation may result from approach/avoidance reactions to the Favorite and Rival teams, respectively. Moreover, we suggest as a corollary that the classic spatial compatibility task is a powerful tool for investigating approach/avoidance effects.

Abstract: In this work limit analysis theorems are exposed in order to study their appliance to the analysis of masonry arches. All this allows studying the role of lines of thrust and curves of pressure on the safety of arches. En este trabajo se enuncian los teoremas de rotura y sus corolarios para aplicarlos al cálculo en rotura de arcos. Después de analizar la teoría de arcos, se estudia el significado de la línea de presiones y de la línea de empujes desde el punto de vista del cálculo a rotura.

Abstract: when a stimulus randomly occurs at left or right, the response is faster when stimulus and response are on the same side (compatible condition) than on opposite sides (incompatible condition). in the simon task, color or shape determines the correct response but it is faster when there is correspondence between stimulus and response key positions. in this research, we studied the simon effect modulation through a previous spatial compatibility task in which just one index finger presses the keys. twenty-eight volunteers run compatibility tasks (14 compatible and 14 incompatible). then, they performed a simon task in which the correct response was selected by shape. a simon effect of 24 ms was found in the compatible group. an inverse simon effect of -16 ms occurred in the incompatible group. these results show long-term memory modulation by task involving short-term memory.

Abstract: when a visual stimulus is randomly displayed either to the left or to the right of the fixation point, manual response is faster when both the response key and the stimulus are located at the same side (compatible condition) than at opposite sides (incompatible condition). in a spatial compatibility task, a difference of 30-40 ms is found between the manual reaction times (mrt) of compatible and incompatible conditions. in the simon effect, though the criterion to response selection is primarily stimulus shape (or color), the stimulus position also influences the mrt, either increasing it in the compatible condition or delaying it in the incompatible condition. the simon effect can be inverted if the subject has recently performed incompatible tasks, showing that short-term memory processes elicited by the incompatible associations can modulate stimulus-response relationships based on long-term memory.

Abstract: objective: aiming to evaluate whether surgery aided navigation offers any advantages over the conventional technique, a randomized, prospective, comparative study was carried out, analyzing the placement of components, alignment of the limb, surgical time, blood loss and functional rehabilitation. material and methods: we studied 39 patients submitted42 total knee arthroplasties. in group 1 (n = 21) the surgery was navigated and in group 2 (n = 21) it was conventional. the patients were evaluated on panoramic radiographs of the lower limbs, ct scan and the knee society score (kss) preoperatively and three months postoperatively. surgery time and postoperative blood loss were also evaluated. results: surgery time was longer in group 1. there was no significant difference in blood loss and the kss. there was a greater proximity of the three degrees of external rotation and the five degrees of tilt in the coronal in group 2. the mechanical axis was closer to zero degree in group conclusions: navigation promotes individualizing of the positioning of the components of the prosthesis, and offered advantages in limb realignment, compared with traditional methods. the surgerytime has a tendency to be higher in group 2, but this difference is not statistically significant. there were no differences between the groups in relation to blood loss and improvement in kss. level of evidence: level i, therapeutic studies.
