Valūtas un valūtas kursa svārstību ierobežošana ilgtermiņa līgumos
2017
Bakalaura darbs „Valūta un valūtas kursa svārstību ierobežošana ilgtermiņa līgumos” sniedz ieskatu jautājumos par maksājuma izdarīšanas valūtu un valūtas kursa svārstību ierobežošanu līgumā. Darba mērķis ir izpētīt, kādā valūtā maksājums izdarāms, ja puses līgumā par to tieši nav vienojušās, kā arī noskaidrot efektīvākos valūtas kursa svārstību ierobežošanas veidus. Pētījuma rezultātā autore konstatē kritērijus, atbilstoši kuriem tiek noteikta maksājuma izdarīšanas valūta un identificē efektīvākos mehānismus valūtas kursa svārstību ierobežošanai līguma ietveros. Atslēgvārdi: valūta, valūtas kurss, valūtas kursa svārstības, darījuma risks, valūtas de-valvācija, valūtas revalvācija.
Reacción emocional ante la exposición involuntaria a cibersexo en adolescentes: factores moduladores
2019
Los avances realizados durante los últimos años en el ámbito de las tecnologías de la información y comunicación han favorecido un uso generalizado de internet. La población adolescente utiliza Internet de forma natural y habitual para comunicarse, entretenerse y realizar tareas escolares. Si bien son múltiples los beneficios derivados del uso de internet, es necesario considerar que no está exento de riesgos como puede ser la exposición involuntaria (EI) a material sexual. Dadas las consecuencias que dicha exposición puede tener (sobre todo en edades tempranas), nuestro objetivo ha sido analizar las principales reacciones a nivel emocional durante la EI a material sexual, explorando posibl…
Environment and Endometriosis: A toxic relationship
2015
Endometriosis is a common, be- nign, estrogen-dependent gynecological dis- ease that represents one of the main causes of hospitalization in industrialized countries. It is well established that a large amount of natural and man-made chemicals are present in the en- vironment and both humans and animals are exposed to them. Dioxin and dioxin-like com- pounds have long biological half-life, can accu- mulate within the organism and could negative- ly affect several physiological processes. The purpose of this review is to provide an overview of the possible relationship between these chemicals and the pathogenesis of en- dometriosis.
Characterization of the Magnetic Induction Field produced by Secondary Substations
2014
The aim of this paper is to develop a methodology for measuring the magnetic field distribution around the prefabricated secondary substations in vibrated reinforced concrete, as well as the definition of a methodology to determining the maximum value of magnetic induction produced by the substations in correspondence to nominal current of the transformer. As proposed has been developed in conformity with laws and standards and can be applied to active and passive secondary substations. The experimental validation of the proposed methodology, carried out by a measurements campaign whose results are reported, confirms the validity and returns a versatile and simple tool for the verification …

Dietary exposure to mycotoxins through the consumption of commercial bread loaf in Valencia, Spain
2017
Abstract In this study, 80 commercial samples of bread loaves were purchased from different supermarkets located in Valencia (Spain). These samples were investigated for the presence of legislated and non-legislated mycotoxins. Results showed that samples were contaminated with Aflatoxins (AFs), Zearalenone (ZEA) and Enniatins (ENs) with a frequency of 20, 96, and 65% respectively. Aflatoxin B1 (AFB1), Aflatoxin B2 (AFB2) and Aflatoxin G1 (AFG1) were detected with concentrations ranged from 0.5 to 7.1 μg/kg. The samples contaminated with AFB1 showed values exceeding the maximum limit allowed in the EU. The sum of AFs also exceeded the maximum limit allowed in 6 samples. ENs contamination da…
The spatial distribution of population exposure to outdoor air pollution in Valencia (Spain) and its association with a privation index
2013
Objetivo: Evaluar la variación espacial de la exposición a dióxido de nitrógeno (NO2) en la ciudad de Valencia y su relación con la privación socioeconómica y la edad. Métodos: La población por sección censal (SC) procede del Instituto Nacional de Estadística. Los niveles de NO2 se midieron en 100 puntos del área de estudio, mediante captadores pasivos, en tres campañas entre 2002 y 2004. Se utilizó regresión por usos del suelo (LUR) para obtener el mapa de los niveles de NO2. Las predicciones del LUR se compararon con las proporcionadas por: a) el captador más cercano de la red de vigilancia, b) el captador pasivo más cercano, c) el conjunto de captadores en un entorno y d) kriging. Se asi…
The relationship between 2D:4D ratio and systemizing and empathy quotients in parents of people with autism spectrum disorders
2011
IntroductionInterdigital 2D:4D ratio has been considered as an indicator of prenatal exposure to androgens, entailing then a smaller ratio more androgenisation. Although it has been related to systemizing and empathy dimensions in the general population, it has never been studied in parents of people with Autism Spectrum Disorders (ASDs).Objectives and aimsTo analyse the relationship between the 2D:4D ratio and these psychological variables in this population.MethodsThe sample was composed by parents of both genders of people with (n = 46) or without (n = 42) ASDs. The ratio was calculated as the mean of 3 measurements of each hand evaluated by 3 different researchers. Psychological dimensi…
Seed dispersal, braeding system, tree density and the spatial pattern of trees – a simulation approach
2002
Summary Tropical tree populations with low densities and with clumped spatial distributions are at risk in the face of fragmentation. It is therefore important to understand factors driving spatial patterns of tree populations. An important set of factors which may influence the spatial pattern of plants, could be the spatial distribution of possible seed sources such as the breeding system (monoecious, dioecious), tree density and the spatial pattern of the parent population. Another set of important factors might be dispersal of seeds away from the parent plants characterised by the mean dispersal distance and by the distribution of dispersal distances (either negative exponential or logn…
<title>Refractive properties of separate erythrocytes of Chernobyl clean-up workers at different pH</title>
2000
This study is focused on the modifications in erythrocytes of Chernobyl nuclear power plant accident clean-up workers as a late health effect of short-term impact of high level radioactive contamination. As a result, a new method based on erythrocyte (RBC) refractive index properties at different pH has been elaborated. According to the light dispersion theory for fluids refractive index is associated with molecules mass m. This feature is widely used for estimation of cell dry mass. But there is another refractive index dependency from molecules charge q regardless of its sing. This feature is not being used for cell quantitative and qualitative characterization. In this study, RBC were in…
