Łojasiewicz exponents, the integral closure of ideals and Newton polyhedra
2003
We give an upper estimate for the Łojasiewicz exponent $\ell(J,I)$ of an ideal $J\subseteq A(K^{n})$ with respect to another ideal I in the ring $A(K^{n})$ of germs analytic functions $f$ : $(K^{n},\mathrm{O})\rightarrow K$ , where $K=C$ or $R$ , using Newton polyhedrons. In particular, we give a method to estimate the Łojasiewicz exponent $\alpha_{0}(f)$ of a germ $f\in A(K^{n})$ that can be applied when $f$ is Newton degenerate with respect to its Newton polyhedron.
Seasonal Changes in Urban PM2.5 Hotspots and Sources from Low-Cost Sensors
2022
PM2.5 concentrations in urban areas are highly variable, both spatially and seasonally. To assess these patterns and the underlying sources, we conducted PM2.5 exposure measurements at the adult breath level (1.6 m) along three ~5 km routes in urban districts of Mainz (Germany) using portable low-cost Alphasense OPC-N3 sensors. The survey took place on five consecutive days including four runs each day (38 in total) in September 2020 and March 2021. While the between-sensor accuracy was tested to be good (R² = 0.98), the recorded PM2.5 values underestimated the official measurement station data by up to 25 µg/m3. The collected data showed no consistent PM2.5 hotspots between September and M…
El comercio exterior de la Unión Europea: Una desagregación regional.
2002
La culminación del proceso de integración europea, con la creación de una única divisa para doce de los países miembros, exige que el comercio exterior de la Unión Europea (UE) sea considerado de una forma unitaria. En este trabajo se analizan los resultados de la modelización de las exportaciones de la UE hacia otras áreas en proceso de integración como NAFTA, Asia-Pacífico y Mercosur, que reciben más del 50 por 100 de las exportaciones de la UE. La utilización de las elasticidades renta y precio de las exportaciones permite obtener una primera aproximación a la influencia de las variables explicativas en este comercio. ismael@uv.es
El fundamento liberal del derecho a la intimidad
2021
T: The right to privacy is configured as a ?retaining wall? against State interference into the private sphere of people?s life. Throughout this work we will try to expose the philosophical-liberal foundations that have led us to what is now conceived as the ?right to privacy?.
Latvijas Universitātes Botāniskais dārzs
2007
Latvijas Universitātes paspārnē devīto gadu desmitu zaļo vecākais botāniskais dārzs Latvijā. Dārza 15 hektāru lielā teritorija ir daļa no Rīgas zaļās rotas ar kultūrvēsturisku vērtību. Tajā ir saglabājušās vairākas 18.–19. gadsimta ēkas – valsts nozīmes koka arhitektūras pieminekļi. Dārza kolekcijās ir augu sugas un to kultūrformas gan no Latvijas, gan no dažādām eksotiskām zemeslodes malām.
Evaluación de la exposición de la población valenciana a micotoxinas a través de un estudio de dieta total
2019
La dieta es la principal fuente de micotoxinas para el hombre. Los hongos micotoxigénicos pueden contaminar los productos vegetales en el campo, durante el almacenamiento o en el procesado. Aunque las micotoxinas son en su mayoría termostables, evaluar su presencia en los diferentes componentes de nuestra dieta incluyendo platos listos para su consumo de composición vegetal y animal, así como en productos lácteos, zumos y bebidas alcohólicas es un paso necesario para evaluar mejor los riesgos asociados a su presencia y adoptar medidas para proteger la salud de los consumidores. En primer lugar, se realizó en esta tesis una revisión bibliográfica que incluyó dieciocho estudios de dieta total…
Anorectal malformations and pregnancy-related disorders: a registry-based case-control study in 17 European regions
2013
Objective To identify pregnancy-related risk factors for different manifestations of congenital anorectal malformations (ARMs).Design A population-based case-control study.Setting Seventeen EUROCAT (European Surveillance of Congenital Anomalies) registries, 1980-2008.Population The study population consisted of 1417 cases with ARM, including 648 cases of isolated ARM, 601 cases of ARM with additional congenital anomalies, and 168 cases of ARM-VACTERL (vertebral, anal, cardiac, tracheo-esophageal, renal, and limb defects), along with 13371 controls with recognised syndromes or chromosomal abnormalities.Methods Multiple logistic regression analyses were used to calculate adjusted odds ratios …
The effects of water absorption and salt fog exposure on agglomerated cork compressive response
2022
The replacement of synthetic foams with agglomerated cork in sandwich composites can meet the increasing environmental concerns. Its peculiar morphology and chemical composition lead to outstanding dimensional recovery that endorsed a broad investigation of its compressive behavior. The knowledge of neat material response is fundamental to obtain a reliable design dataset, but it is necessary to consider all the environmental factors (water, moisture and sunlight) that significantly modify material mechanical properties. In view of this, the present work investigates the effect of distilled and seawater absorption and salt fog exposure on the compressive behavior of two agglomerated corks w…
Molecular mechanisms of endomembrane trafficking in plants
2021
Abstract Endomembrane trafficking is essential for all eukaryotic cells. The best-characterized membrane trafficking organelles include the endoplasmic reticulum (ER), Golgi apparatus, early and recycling endosomes, multivesicular body, or late endosome, lysosome/vacuole, and plasma membrane. Although historically plants have given rise to cell biology, our understanding of membrane trafficking has mainly been shaped by the much more studied mammalian and yeast models. Whereas organelles and major protein families that regulate endomembrane trafficking are largely conserved across all eukaryotes, exciting variations are emerging from advances in plant cell biology research. In this review, …
