Miguel Esteve (Xàtiva, h.1485 - Valencia, 1527) y algunas consideraciones más sobre la pintura valenciana de su época

2015

Mi línea de investigación trata sobre la pintura valenciana del siglo XVI, cuyos resultados se ven reflejados fundamentalmente en los diferentes artículos publicados en revistas científicas a los que hago mención específica a continuación, como también en colaboraciones puntuales en catálogos de exposiciones y demás. Más en concreto, mi campo de estudio y mis aportaciones originales se centra en un conjunto de pintores cuya obra delata en gran medida la influencia que Fernando Yáñez de la Almedina y Fernando Llanos, tras su paso por Valencia, ejercieron en toda su producción. Estos pintores son, en primer lugar Miguel Esteve (Xàtiva, h.1485 – Valencia, 1527), cuya obra documentada –y en par…

Monitoring WWTP performance using size-exclusion chromatography with simultaneous UV and fluorescence detection to track recalcitrant wastewater frac…

2018

A trial monitoring of a typical full-scale municipal WWTP in Central Finland was aimed to explore applicability of high performance liquid chromatography – size exclusion chromatography (HPSEC) with simultaneous UV and fluorescence detection as a tool for advanced routine monitoring of wastewater treatment. High, intermediate, and low molecular weight (MW) fractions of untreated wastewater (influent) and treated wastewater (secondary effluent) were characterized in terms of UV absorbance at 254 nm (UVA254) and specific fluorescence representing tyrosine-like, tryptophan-like, and humic/fulvic-like compounds. The activated sludge treatment removed 97 ± 1% of BOD, 93 ± 2% of COD, 71 ± 7% of D…

Evaluation of the Behavior of Phenolic Compounds and Steviol Glycosides of Sonicated Strawberry Juice Sweetened with Stevia (Stevia rebaudiana Berton…

2019

In this study, the influence of stevia addition and sonication processing parameters on the phenolic content and profile as well as the steviol glycosides of strawberry juice-based samples was investigated. For this purpose, three matrices&mdash

Removal of ammonium ions from aqueous solutions using alkali-activated analcime as sorbent

2023

Five alkali-activated analcime (ANA) sorbents (ANA-MK 1, ANA 2, ANA 3, ANA-MK 4, and ANA-MK 5) were developed for ammonium (NH4+) ion removal. Acid treatment and calcination were used as pre-treatments for analcime, and metakaolin (MK) was used as a blending agent in three sorbents. Sorption experiments were performed to evaluate the effects of sorbent dosage (1–20 g L−1), initial NH4+ ion concentration (5–1000 g L−1), and contact time (1 min–24 h). ANA-MK 1, ANA 2, and ANA-MK 4 were the most efficient sorbents for NH4+ ion removal, with a maximum experimental sorption uptake of 29.79, 26.00, and 22.24 mg g−1, respectively. ANA 3 and ANA-MK 5 demonstrated…

Optical Monitoring of Microplastics Filtrated from Wastewater Sludge and Suspended in Ethanol.

2021

The abundance of microplastics (MPs) in the atmosphere, on land, and especially in water bodies is well acknowledged. In this study, we establish an optical method based on three different techniques, namely, specular reflection to probe the medium, transmission spectroscopy measurements for the detection and identification, and a speckle pattern for monitoring the sedimentation of MPs filtrated from wastewater sludge and suspended in ethanol. We used first Raman measurements to estimate the presence and types of different MPs in wastewater sludge samples. We also used microscopy to identify the shapes of the main MPs. This allowed us to create a teaching set of samples to be characterized …

Simultaneous determination of five antibiotics in urban wastewater using SPE-HPLC-MS/MS

2015

Antibioottien havaitseminen jätevesistä on haastavaa johtuen matalista pitoisuuksista ja monimutkaisesta matriisista. Tässä työssä kehiteltiin kiinteäfaasiuuttoa, nestekromatografia ja tandem massaspektrometriä hyväksi käyttävä menetelmä, jolla voitiin analysoida viittä antibioottia yhtäaikaisesti matalina pitoisuuksina jätevesistä, ja sitä testattiin käytännössä kolmen keskisuuren suomalaisen jätevedenpuhdistamon jätevesiin. Monimutkainen matriisi heikentää usein antibioottien signaalia massaspektrometrissä ja tässä työssä käytettiin matriisi-korjattua ulkoista standardia huomioimaan efektiä. Mene-telmä oli yksinkertainen, nopea ja toistettava. Määritysrajat vaihtelivat <10–150 ng/l välill…

­Cardiac cycle and respiration phase affect responses to the conditioned stimulus in young adults trained in trace eyeblink conditioning

2022

Rhythms of breathing and heartbeat are linked to each other as well as to rhythms of the brain. Our recent studies suggest that presenting the conditioned stimulus during expiration or during the diastolic phase of the cardiac cycle facilitates neural processing of that stimulus and improves learning an eyeblink classical conditioning task. To date, it has not been examined whether utilizing information from both respiration and cardiac cycle phases simultaneously allows even more efficient modulation of learning. Here we studied whether the timing of the conditioned stimulus to different cardiorespiratory rhythm phase combinations affects learning trace eyeblink conditioning in healthy you…
