BACKGROUND The most commonly primary intramedullary spinal cord tumors (ISCT) in adults are the noninfiltrative lesions, corresponding to Klekamp's type A classification. There are few reports exclusively considering this type of lesions, their resectability and postoperative functional declination risk, and to our knowledge, none from Latin America. This led us to evaluate our results to provi...

The angular declination of a target with respect to eye level is known to be an important cue to egocentric distance when objects are viewed or can be assumed to be resting on the ground. When targets are fixated, angular declination and the direction of the gaze with respect to eye level have the same objective value. However, any situation that limits the time available to shift gaze could le...

This study investigates F0 declination in broadcast news speech in English and Mandarin Chinese. The results demonstrate a strong relationship between utterance length and declination slope. Shorter utterances have steeper declination even after excluding the initial rising and final lowering effects. Both topline and baseline show declination, but they are independent. The topline and baseline...

[1] The daily variation of the geomagnetic field during quiet time at equinox features a longitudinal dependence, which is observed in the dip-latitude/longitude frame. Two explanations are considered: (1) the longitudinal changes of the geomagnetic latitude at constant dip-latitude and (2) the longitudinal variations of the main field, which modulates the ionospheric dynamo e.m.f. and determin...

A comparative study is carried out between a semi-empirical low-latitude ionospheric model (SLIM). including calculated 01 630 nm airglow emission intensities predicted by the SLIM model, with ionospheric and r>I 630 nm airglow measurements carried out at Cachoeira Paulista (22.7”S, 45.O”W; geomag. 11.9”S), Brazil. A long series of regular measurements of ionospheric F-region peak electron dens...

This paper deals with F0 declination in Russian. The study was conducted using statistical data derived from the Corpus of Professionally Read Speech. The results confirm the relationship between F0 slope and the utterance length for Russian. At the same time they reveal a) individual strategies in preplanning declination slope of the phrase or utterance; b) strong dependency of the F0 slope on...

depth estimation of the top of the bedrock in the sedimentary basins is the main goal in geomagnetic explorations. the depth estimation of this kind of anomalies can be done using different methods, in the cases where the bedrock is magnetized. in this article, we use the standard euler deconvolution method and its results to interpret the magnetic data from the reshm region in semnan province ...
