[Changes in nasal resistance as a result of posture in normal subjects].
No full textThe variations of nasal resistance, after lateral right, lateral left and supine recumbency have been studied in 20 normal subjects. These variations were in order of constant succession by rhinomanometry. In lateral right recumbency (first recumbency), the mean increase of nasal resistance in lower nasal cavity was 35%; on the contrary in the following recumbency the increase was twice as large as the first one. In supine recumbency the results were abnormal. In fact, with respect to the same nasal cavity, some of our subjects showed a congestion, while some showed a decongestion. It may be concluded that utilization of postural tests, like index vasomotor reactivity, must keep the increase of nasal resistance in normal subject, following postural variations in mind, in order to express a judgement of significative pathological difference

The Dirichlet problem for the 1-Laplacian with a general singular term and L1-data
No full textWe study the Dirichlet problem for an elliptic equation involving the 1-Laplace operator and a reaction term, namely: 'Equation Presented', where Ω ⊂ RN is an open bounded set having Lipschitz boundary, f ∈ L1(Ω) is nonnegative, and h is a continuous real function that may possibly blow up at zero. We investigate optimal ranges for the data in order to obtain existence, nonexistence and (whenever expected) uniqueness of nonnegative solutions
[Nasal provocation test with histamine: rhinomanometry study of normal subjects].
No full textNasal reactivity to histamine was evaluated in 40 normal subjects. The application of a chloride histamine solution (1 mg) registered in 90% of the subjects the appearance of sneezing with the number of sneezes ranging between one and fourteen (5.7 +/- 3.76) and an average increase in the total resistence in the inspiration phase of 93.1% (+/- 63.2) and in the expiration phase of 98.1% (+/- 60.5) with a range between 37.7% and 24.1%. The authors conclude that sneezing and above all nasal congestion evaluated rhinomanometrically represent two important parameters in the evaluation of nasal reaction; an increase greater than or equal to 200% of the total nasal resistance can surely be considered an index of nasal hyperreactivity
[Nasal provocation test with hyperosmolar solutions: normal values].
No full textHyperosmolar solutions have recently been introduced as test-substances in the nasal provocation of vasomotor rhinitis subjects. In order to establish a norm, the test was carried out in 40 subjects without nasal pathologies, stimulating with solutions at increasing level of concentrations of NaCl (0.9% - 1.8 - 3.6% - 5.4% - 7.2% - 9%). In all subjects an increase in nasal secretion was verified in proportion to the concentration of the solutions and this increase was statistically significative, with respect to the base, from the concentration 3.6% (p less than 0.001) on words. The statistical analysis has not, however, evidenced any significant differences in secretion between male or female subjects. As far as the variation of nasal resistance is concerned, the rhinomanometric registration has revealed that the hypertonic solutions modify such resistances in a rather casual, absolutely irregular and unimportant way. These results lead to believe that the test is extremely useful in the study of the secretion component of vasomotor rhinopathy

Autonomous crater detection on asteroids using a fully-convolutional neural network
No full textThis paper shows the application of autonomous Crater Detection using a Fully-Convolutional Neural Network (FCN) on a main belt asteroid, Ceres. The FCN, namely a U-Net, is trained on optical images of the Moon Global Morphology Mosaic based on data collected by the Lunar Recoinnassance Orbiter (LRO), using manual crater catalogues as annotations for the creation of ground truth data. The Moon-trained network will then be tested on optical images of Ceres taken during the Dawn mission; as this network is adapted to a different domain from the one upon which it was already trained, this task is accomplished by means of a Transfer Learning (TL) approach. In particular, this work will take into consideration a homogeneous TL, because the image features and labels share the same qualities in both domains. The Moon-trained model has been fine-tuned using 100, 500 and 1000 additional annotated images of Ceres, reaching a testing accuracy on 350 never before seen images of 96.24%, 96.95% and 97.19%, respectively. Annotations for Ceres are taken from the Zeilnhofer crater catalogue, containing 44.594 craters with diameter greater than 1 km in a latitude range of 84.66°S-89.62°N, full longitude: therefore, a near-global coverage of the asteroid surface will be taken into consideration.
The output of the U-Net is a grey-scale mask containing predicted craters: it will be post-processed applying global thresholding for image binarization and a template matching algorithm to extract craters positions and radii in the pixel space: this allows the creation of a definitive binary mask. These post-processed craters will be counted and compared to the ground truth data in order to compute image segmentation metrics: precision, recall and their harmonic mean known as F1 score. Precision, which is the ratio between matched craters and all the craters found by the network, reached values of 70.51%, 84.43% and 83.45%. Recall, defined as the ratio between matched and catalogued craters, achieved performances of 48.27%, 53.32% and 58.97%; the lower values are due to the fact that when precision is high, recall is automatically penalized and vice versa. The F1 score is introduced to sum up the effects of both the above indices: its reached percentages are 57.30%, 65.36% and 69.11%. These results are considered to be encouraging because they are comparable with other works that use the U-Net in a Crater Detection contex

Divisa Roja: semanario liberal, ciencia, variedades, artes
No full text“Divisa Roja: semanario liberal, ciencia, variedades, artes” fue una publicación que circuló en el Municipio de Facatativá (Departamento de Cundinamarca) durante el periodo 1912-1913. El periódico fue fundado por Luis F. Latorre U. y se estableció como una tribuna de defensa, promoción y análisis de la doctrina liberal en la región. En sus páginas se da cuenta de la división interna del liberalismo y la cercanía de algunos de sus adeptos al partido republicano. Además de lo mencionado, se reproducen noticias relacionadas con la cercanía de la legislación obrera y la política liberal. En el aspecto internacional, se da cuenta de los levantamientos de Ecuador de 1912 que involucraron a los generales Eloy Alfaro y Julio Andrade y la Guerra de los Balkanes.P039
