A benthic bioindicator is applied for the first time in water quality monitoring in streams in Uruguay using diatoms. These microalgae are the most diverse group and usually constitute 80-90 % of periphyton. They are recognized throughout the world for their value as indicators of eutrophication and organic pollution because they respond quickly to environmental changes and provide information on the biotic integrity of aquatic ecosystems. Thanks to these characteristics, water quality indexes have ...

Abstract Nanopigmented and fiber‐reinforced poly (methyl methacrylate) (PMMA) were synthesized for denture bases, by incorporating E‐glass fibers, flock fibers, or polyethylene fibers into the PMMA powder formulation to improve the flexural behavior and porosity; decreasing the Candida albicans adherence and being noncytotoxic. The commercial acrylic resin, Lucitone 199 was used as a control group. Scanning electron microscopy analysis was performed to the PMMA particles and the reinforcing fibers. ...

Many denture wearers suffer from fungal infections, particularly Candida albicans, due to failure to properly clean or remove the prosthesis. These infections can cause denture stomatitis, which often leads to irritated or traumatized tissues. Current denture base materials do not have antifungal properties. We have recently synthesized several new antifungal compounds containing 1,4-diazabicyclo [2.2.2] octane (DABCO) (DC16NF, DC11MAF, C2-DC11MAF) that have shown significant antifungal properties. ...

The formation of precipitate free zones (PFZ) along large and small angle grain boundaries has been investigated for bi- and polycrystals of the nickel-base superalloy NIMONIC PE16. This material is strengthened by coherent precipitates of the γ′-phase. The most important result is that the PFZs are caused by the growth of titanium-rich carbides in the grain boundaries. Since titanium is a constituent of the γ′-precipitates, its depletion along the grain boundaries leads to the dissolution of the ...

Abstract DNA sequences comprising noncanonical 7‐deazaguanine ( 7C G) and canonical cytosine (C) are capable of forming Watson–Crick base pairs via hydrogen bonds as well as silver(I)‐mediated base pairs by coordination to central silver(I) ions. Duplexes I and II containing 7C G and C have been synthesized and characterized. The incorporation of silver(I) ions into these duplexes has been studied by means of temperature‐dependent UV spectroscopy, circular dichroism, and DFT calculations. The results ...

Scarce morphometric data exist on the developing skull base as a corridor for endonasal endoscopic approaches (EEAs). Furthermore, the impact of skull base lesions on its development has not been assessed. The authors describe a novel set of anatomical parameters characterizing the developmental process as well as the utility of these parameters in preoperative planning and a feasibility assessment of EEAs for neurosurgical treatment of skull base lesions in children.Based on specific MRI sequences ...

Argininosuccinate lyase deficiency (ASLD) is a recessive metabolic disorder caused by variants in ASL. In an essential step in urea synthesis, ASL breaks down argininosuccinate (ASA), a pathognomonic ASLD biomarker. The severe disease forms lead to hyperammonemia, neurological injury, and even early death. The current treatments are unsatisfactory, involving a strict low-protein diet, arginine supplementation, nitrogen scavenging, and in some cases, liver transplantation. An unmet need exists for ...

Uno de los rasgos más destacados del populismo es su empleo de las emociones. Sin embargo, los análisis de la dimensión emocional del populismo suelen adolecer de cierta superficialidad. Este trabajo persigue, justamente, arrojar luz sobre las bases afectivas del populismo.

Photorefractive (PR) materials are ideal for potential applications in real-time optical processing. We report new highly efficient organic photorefractive polymers based on the nonlinear chromophores 4-[(4-(diethylamino)-2-hydroxybenzylideneamino]benzonitrile (Dc) and 4-[4-(diethylamino)benzylideneamino]benzonitrile (Ds). Holographic experiments in a four wave mixing (FWM) and two beam coupling (TBC) geometries were carried out by using a He–Ne laser (633 nm). The electric field steady-state diffraction ...

Base-of-slope aprons that lack significant channel development and are fed by multiple sediment sources (i.e., numerous slope failures or debris chutes) represent an alternative facies organization to submarine fans that possess channels and are fed by canyon point sources of allochthonous sediment. Two styles of base-of-slope apron deposition are evident: (1) sand-rich aprons with rhythmic, gradational sand and gravel sheets that evolve to basin-plain turbidites as exemplified by Crater Lake aprons, ...
