Two-dimensional semiconducting materials are particularly appealing for many applications. Although theory predicts a large number of two-dimensional materials, experimentally only a few of these materials have been identified and characterized comprehensively in the ultrathin limit. Lead iodide, which belongs to the transition metal halides family and has a direct bandgap in the visible spectrum, has been known for a long time and has been well characterized in its bulk form. Nevertheless, studies of this material in the nanometer thickness regime are rather scarce...

Upper tropospheric equatorial westerly ducts over the Pacific Ocean are the preferred location for Rossby wave breaking events during boreal winter and spring. These subtropical wave breaking events lead to the intrusion of high PV (potential vorticity) air along the extra-tropical tropopause and transport ozone rich dry stratospheric air into the tropics. The intrusion frequency has strong interannual variability due to ENSO (El-Niño/Southern Oscillation), with more events under La-Niña and less under El-Niño conditions...

The strong El Niño Southern Oscillation (ENSO) event that occurred in 2015/2016 caused extreme drought in the northern Brazilian Amazon, especially in the state of Roraima, increasing fire occurrence. Here we map the extent of precipitation and fire anomalies and quantify the effects of climatic and anthropogenic drivers on fire occurrence during the 2015/2016 dry season (from December 2015 to March 2016) in the state of Roraima. To achieve these objectives we first estimated the spatial pattern of precipitation anomalies, based on long-term data from the TRMM (Tropical Rainfall Measuring Mission), and the fire anomaly, based on MODIS (Moderate Resolution Imaging Spectroradiometer) active fire detections during the referred period...

Multiple interprofessional integrated modules (MIIM) 1 and 2 are two required, cross-curricular courses developed by a team of health professions faculty, as well as experts in education, within the Faculty of Medicine of the University of Chile. MIIM 1 focused on virtual cases requiring team decision-making in real time. MIIM 2 focused on a team-based community project. The evaluation of MIIM included student, teacher, and coordinator perspectives. To explore the perceptions of this interprofessional experience quantitative data in the form of standardised course evaluations regarding teaching methodology, interpersonal relations and the course organisation and logistics were gathered...

BACKGROUND: There is evidence from existing literature that ambient air pollutant exposure in early childhood likely plays an important role in asthma exacerbation and other respiratory symptoms, with greater effect among asthmatic children. However, there is inconclusive evidence on the role of ambient air pollutant exposures in relation to increasing asthma prevalence as well as asthma induction in children. At the population level, little is known about the potential synergistic effects between pollen allergens and air pollutants since this type of association poses challenges in uncontrolled real life settings...

The reactivity of an iron monosulfide surface exposed at room temperature to molecular nitrogen and hydrogen sulfide has been investigated using X-ray photoemission spectroscopy (XPS) and thermal desorption spectroscopy (TDS). We have observed adsorption of nitrogen at room temperature that depends on the surface nanostructure and on the electronic state of nitrogen. The subsequent reaction of this adsorbed nitrogen with hydrogen sulfide results in depletion of the nitrogen surface content which can be interpreted in terms of ammonia formation...

The Western Ghats (WG) of India are basically north-south oriented mountains having narrow zonal width with a steep rising western face. The summer monsoon winds during June to September passing over the Arabian Sea are obstructed by the WG and thus orographically uplift to produce moderate-to-heavy precipitation over the region. However, it is seen that characteristic features of rainfall distribution during the season vary from north to south. Also its correlation with all-India summer monsoon rainfall increases from south to north...

Physical deformations are observed at the top electrodes during the electroforming process in Al/PEDOT:PSS + nitrogen doped multiwalled carbon nanotube (N-MWCNTs)/Al rewritable resistive memory devices. These physical deformations arise from electrochemical reactions, i.e., a reduction reaction in the native Al oxide layer, which are similar to those reported in TiO2-based resistive memory devices. These memory devices are electroformed at the ON state using an ∼-2 V pulse or at the OFF state using an ∼3 V pulse...

We monitored soil CO 2 effluxes for over 3 years in a seasonally wet tropical forest in Central Panama using automated and manual measurements from 2013 to 2016. The measurements displayed a high degree of spatial and temporal variability. Temporal variability could be largely explained by surface soil water dynamics over a broad range of temporal scales. Soil moisture was responsible for seasonal cycles, diurnal cycles, intraseasonal variability such as rain-induced pulses following dry spells, as well as suppression during near saturated conditions, and ultimately, interannual variability...

Retropharyngeal and parapharyngeal abscesses are rare but associated with significant morbidity and potential mortality. In recent years, there has been an increase in the incidence of these infections, mainly due to a greater availability of computed tomography scan and a greater virulence of the germs (Group A b-hemolytic Streptococcus and methicillin-resistant Staphylococcus aureus). They predominate in children younger than 5 years. Treatment of retropharyngeal and parapharyngeal abscesses consists of an intravenous antibiotic and eventually surgical drainage...
