Nanoparticles of Ni(OH)2 surrounded with ultra-low Pt content and supported on functionalized carbon were prepared by a scalable synthesis method and investigated as electrocatalysts for the oxygen reduction reaction (ORR) in acidic media. The effect of altering the Pt surface composition on the Ni(OH)2 nanoparticle core was investigated as a route to simultaneously increase the ORR activity and stability. Modifying the Pt surface composition resulted in both structural and electronic changes. Decreasing ...

En los tres primeros lustros del siglo XXI las ciudades españolas han dispuesto de un ingente caudal normativo, extremadamente sensible al cambio político y por lo tanto generador de incertidumbre, que en la práctica ha hecho críptica y laberíntica la gestión urbanística urbana y regional. A todo ello se añade una reiterada sucesión de errores y discrepancias en torno a la interpretación de la Ley 8/2007 de Suelo, y una apropiación política de la ciudad, en cada ciclo regulador, que hace bascular ...

A colorimetric diacid monomer for aromatic diamine sensing containing the urea binding site has been synthesised and characterised. A colour development from colourless to blue, brown or yellow was observed upon addition of metha, para or ortho-phenylenediamine, respectively, to polar aprotic organic solvent solutions of the monomers. The solutions remained colourless upon addition of other amines or diamines. The model polyamide compound derived from the diacid monomer maintains the colorimetric ...

Ultrasonography (US) is currently the reference technique for evaluating gallbladder pathology. The aim of this study was to prospectively determine the diagnostic efficacy of magnetic resonance cholangiography (MRCP) in evaluating the gallbladder, as compared with US. The study included 80 patients (mean age, 69.3 years; male-to-female ration, 1.3:1) who underwent prospective US and MRCP; 5 patients in whom MRCP was contraindicated were excluded. In all cases, US was performed before MRCP. Ultrasound ...

This strategy enables information to be gathered on the perceptions, beliefs, and values of a group's participants and is particularly well suited to addressing cultural characteristics that impact on a population's health status. As nations become more culturally diverse, qualitative research will likely play a growing role in helping health professions educators develop appropriate educational programs ...

Lophophora williamsii (commonly named peyote) is a small, spineless cactus with psychoactive alkaloids, particularly mescaline. Peyote utilizes crassulacean acid metabolism (CAM), an alternative form of photosynthesis that exists in succulents such as cacti and other desert plants. Therefore, its transcriptome can be considered an important resource for future research focused on understanding how these plants make more efficient use of water in marginal environments and also for research focused ...

Density is crucial for understanding large carnivore ecology and conservation, but estimating it has proven methodologically difficult. We conducted 1 year of camera trapping to estimate jaguar (Panthera onca) density and population structure in the Los Llanos region of Venezuela on the Hato Piñero ranch, where hunting is prohibited and livestock are excluded from half of ranch lands. We identified 42 different jaguars and determined their sex, age class, and reproductive status. We estimated adult ...

Aluminum-based alloys have been considered candidate materials for cathodic protection anodes. However, the Al-based alloys can form a layer of alumina, which is a drawback in a sacrificial anode. The anodes must exhibit uniform corrosion to achieve better performance. Aluminum can be alloyed with Zn to improve their performance. In this sense, in the present research, the electrochemical corrosion performance of Al-xZn alloys (x = 1.5, 3.5, and 5 at.% Zn) exposed to 3.5 wt.% NaCl for 24 h was evaluated. ...

The evidence of glomerular filtration rate (GFR) estimating with serum creatinine based formulae in the elderly population is scarce. The purpose of this study is to compare CKD-EPI, MRD4-IDMS and BIS1 equations to analyze correlation and concordance in a population older than 85 years old. We designed a retrospective cross-sectional study, which included data from 600 patients older than 85 years.
