Solar Orbiter is a joint ESA-NASA mission planed for launch in October 2018. The science payload includes remote-sensing and in-situ instrumentation designed with the primary goal of understanding ...how the Sun creates and controls the heliosphere. The spacecraft will follow an elliptical orbit around the Sun, with perihelion as close as 0.28 AU. During the late orbit phase the orbital plane will reach inclinations above 30 degrees, allowing direct observations of the solar polar regions. The Energetic Particle Detector (EPD) is an instrument suite consisting of several sensors measuring electrons, protons and ions over a broad energy interval (2 keV to 15 MeV for electrons, 3 keV to 100 MeV for protons and few tens of keV/nuc to 450 MeV/nuc for ions), providing composition, spectra, timing and anisotropy information. We present an overview of Solar Orbiter from the energetic particle perspective, summarizing the capabilities of EPD and the opportunities that these new observations will provide for understanding how energetic particles are accelerated during solar eruptions and how they propagate through the Heliosphere.
Nowadays, avocado has strong demand around the world due to its nutritional properties and because it is all year supplied from different parts of the world, being Peru one of the main providers. ...However, nutrient deficiencies and plague attacks during cultivation stages represent a major difficulty for farmers since early identification of these states (i.e. deficiencies and plagues) is a time-consuming activity that requires trained evaluators to do so. In this paper, an automatic method for identification of avocado leaf state is proposed. This method uses k-means, in a s-v space at superpixel level, to segment leaf from uniform background from images captured in-field in semi-controlled conditions and a shallow neural network to classify composed histograms from segmented leaves into 4 states: Healthy, Fe deficiency, Mg deficiency and red spider plague. The proposed method separates leaf from background with an average F-score of 0.98 and classifies leaf condition with an overall accuracy of 96.8%.
Plants growing in the Caribbean, Rubia tinctorum, Lippia dulcis and Spermacoce remota, were used in vitro to remove TNT from culture media. Plants were found to be resistant to high TNT levels. S. ...remota was able to remove TNT in less than 48 h. Part of the TNT was physically removed from the culture media by evaporation.
Phys. Rev. C 97, 044609 (2018) Cross sections for elastic and inelastic scattering of the weakly-bound
$^9$Be nucleus on a $^{120}$Sn target have been measured at seven bombarding
energies around and ...above the Coulomb barrier. The elastic angular
distributions are analyzed with a four-body continuum-discretized
coupled-channels (CDCC) calculation, which considers $^9$Be as a three-body
projectile ($\alpha$ + $\alpha$ + n). An optical model analysis using the S\~ao
Paulo potential is also shown for comparison. The CDCC analysis shows that the
coupling to the continuum part of the spectrum is important for the agreement
with experimental data even at energies around the Coulomb barrier, suggesting
that breakup is an important process at low energies. At the highest incident
energies, two inelastic peaks are observed at 1.19(5) and 2.41(5) MeV.
Coupled-channels (CC) calculations using a rotational model confirm that the
first inelastic peak corresponds to the excitation of the 2$_1^+$ state in
$^{120}$Sn, while the second one likely corresponds to the excitation of the
3$_1^-$ state.
A 3-year-old girl was evaluated for persistent middle lobe atelectasis. Fiberoptic bronchoscopy revealed a spherical mass occupying the middle-lobe bronchus. The biopsy specimen disclosed a low-grade ...mucoepidermoid carcinoma. A lobectomy was performed. The patient is in good condition 2 years after the operation. Mucoepidermoid tumors are rare bronchial adenomas comprising 1% of all lung neoplasms. Children are very infrequently affected. The clinical behavior of these tumors is controversial. Surgical resection of the low-grade-type tumor has an excellent prognosis.
Urachal sinus is a rare congenital anomaly due to incomplete closure the urachus in the umbilical region, it is very rare in adults. 47-year-old male who arrived at our Emergency Department with ...recurrent umbilical discharge. Not response medical treatment (oral antibiotic and drainage). Abdominal computerized tomography scan confirmed the urachal sinus with omphalitis. Surgical complete excision with omphalectomy was performed. Any complications in the postoperative was observed.

Chagas disease constitutes a relatively prevalent condition in Latin America and is increasing worldwide. With a wide spectrum of clinical subsets. Imaging modalities are critical for adequate ...diagnosis, staging and prognosis of this entity. Currently Echocardiography and Cardiac Magnetic Resonance are the most valuable techniques for this purpose. Evidence for both modalities has increased in the last years, as the role of advanced techniques such as Speckle Tracking Echocardiography has been explored we aim to review the evidence of advanced imaging in the spectrum of patients with Chagas Heart Disease.
