Francoism and the republican Eexiles: the case of the composer Julián Bautista (1901–61)
Exile studies in musicology have generally focused on Central European exiles fleeing from Nazism; at the same
time studies of the Republican exile following the Spanish Civil War have tended to deal primarily with writers
rather than musicians. This article intends to address both these areas of neglect by focusing on the composer
Julia´n Bautista, who settled in Buenos Aires in 1940. In the late 1950s, after more than a decade of oblivion in
his home country, Bautista, like other anti-Francoist exiles, started to become the object of interest again in
Spain, an interest which continued after the composer’s death in 1961. By exploring Bautista’s presence in the
Francoist musical press and in high-profile, state-sponsored events such as the Festivales de Música de América
y España, I shall explore the reasons for his rehabilitation – reasons that, far from amounting to straightforward
liberalization, seem to have been closely aligned with the strategies of the régime, and the cultural values and
historical narratives that underpinned them

De Politieke Strijd om Veiligheid: Regulering versus spontaniteit in de partijprogramma's
Veiligheid is een topprioriteit voor politieke partijen. Diepgaande analyse van partijprogramma's leert dat er een algemene toename is van de nadruk op repressieve regulering van de samenleving, en een afname van steun voor het stimuleren van spontane burgers
Determination of fatty acids ethyl esters in virgin olive oils: proposals to enhance the EU official method
Fatty acids ethyl esters (FAEEs) are markers for virgin olive oils obtained from olives of poor quality or not
adequately stored before being processed. FAEEs can also be considered as indirect markers in detecting the
illegal treatment of soft deodorization that can be applied to slightly defective olive oils, as they are difficult to be
removed from the oils at the conditions reached during this technological process. The official FAEEs determination
(EU Reg. 61/2011) suffers some drawbacks in terms of amount of solvents and long time of analysis, linked with the
preparative procedure to isolate these compounds.
The aim of this work is to study the application of an HPLC-UV as a rapid alternative approach to the traditional
liquid chromatography applied in the preparative phase. After the set up of the most appropriate working conditions
(eg. mobile phase, flow, injection volume), some validation parameters (eg. precision, accuracy, LOD and LOQ,
recovery) have been evaluated, in order to check the effectiveness of the proposed method. Moreover, considering
the GC-FID step, the use of a PTV (programmed temperature vaporizer) injector as an alternative of the on-column
one was evaluated.
This work is developed in the context of the project OLEUM \u201cAdvanced solutions for assuring authenticity and quality
of olive oil at global scale\u201c, funded by the European Commission within the Horizon 2020 Programme (2014\u20132020,

Large-scale evaluation of shotgun triacylglycerol profiling for the fast detection of olive oil adulteration
Fast and effective analytical screening tools providing new suitable authenticity markers and applicable to a large number of samples are required to efficiently control the global olive oil (OO) production, and allow the rapid detection of low levels of adulterants even with fatty acid composition similar to OO. The present study aims to develop authentication models for the comprehensive detection of illegal blends of OO with adulterants including different types of high linoleic (HL) and high oleic (HO) vegetable oils at low concentrations (2–10%) based on shotgun triacylglycerol (TAG) profile obtained by Flow Injection Analysis-Heated Electrospray Ionisation-High Resolution Mass Spectrometry (FIA-HESI-HRMS) at a large-scale experimental design. The sample set covers a large natural variability of both OO and adulterants, resulting in more than one thousand samples analysed. A combined PLS-DA binary modelling based on shotgun TAG profiling proved to be a fit for purpose screening tool in terms of efficiency and applicability. The external validation resulted in the correct classification of the 86.8% of the adulterated samples (diagnostic sensitivity = 0.87), and the 81.1% of the genuine samples (diagnostic specificity = 0.81), with an 85.1% overall correct classification (efficiency = 0.85)
Stepwise strategy based on 1H-NMR fingerprinting in combination with chemometrics to determine the content of vegetable oils in olive oil mixtures
1H NMR fingerprinting of edible oils and a set of multivariate classification and regression models organised in a decision tree is proposed as a stepwise strategy to assure the authenticity and traceability of olive oils and their declared blends with other vegetable oils (VOs). Oils of the ‘virgin olive oil’ and ‘olive oil’ categories and their mixtures with the most common VOs, i.e. sunflower, high oleic sunflower, hazelnut, avocado, soybean, corn, refined palm olein and desterolized high oleic sunflower oils, were studied. Partial least squares (PLS) discriminant analysis provided stable and robust binary classification models to identify the olive oil type and the VO in the blend. PLS regression afforded models with excellent precisions and acceptable accuracies to determine the percentage of VO in the mixture. The satisfactory performance of this approach, tested with blind samples, confirm its potential to support regulations and control bodies

Characterization of Glyceridic and Unsaponifiable Compounds of Sacha Inchi ( Plukenetia huayllabambana
This work deals with the characterization of the main glyceridic and unsaponifiable components of oils obtained from Sacha inchi (Plukenetia huayllabambana L.) seed ecotypes collected during two harvests in the Department of Amazonas in Peru. The seed-oil yield was 30.3-41.2%; standing out are the high percentages of the ¿3- and ¿6-fatty acids series whose ranges lie within those of the present Regulation for Sacha inchi oils. Triacylglycerols with even equivalent carbon number (ECN; 36-42) were the main components. Minor glyceridic polar compounds such as oxidized triglycerides, diglycerides, monoglycerides, and free fatty acids were determined by high-performance size exclusion chromatography. The low campesterol/stigmasterol ratio (1:6), unusual in the majority of vegetable oils, stands out. Regarding aliphatic hydrocarbons, these oils showed a particular profile for the saturated series of odd and even carbon atom numbers. According to our results Sacha inchi P. huayllabambana oils can be offered as a good alternative to P. volubilis, the species mainly commercialized for this vegetable oil
Impact of regulated and emerging pollutants and microplastics in marine ecosystems (IMPACTA project)
Marine ecosystems are nowadays subjected to a massive input of synthetic chemicals from everywhere. Unfortunately only a small portion of them is being monitored, and it is necessary to identify which pollutants can produce adverse impacts in the marine environment. IMPACTA project (CTM2013-48194-C3) is characterizing the distribution of regulated and emerging contaminants and microplastics in marine sediments, and evaluating the biological effects that they can cause (sing sublethal embryotoxicity tests, endocrine disruption and biomarkers). Sensitive and selective analytical methods are being developed and validated for pharmaceuticals, perfluorinated compounds, organophosphorus pesticides, triazines, personal care products, nonylphenols and alkylated PAHs in sediments. Thus, relevant pollutants present in coastal and offshore areas will be identified. Furthermore potential toxic effects of the contaminants present in coastal sediments are being assessed through embryotoxicity bioassays and also the biological effects on different marine species as a consequence of their exposition to specific compounds.
Another relevant contribution of this project will be the assessment of the impact of micro-plastics, first time in the Spanish coastal areas. Their potential toxic effects and their role in the transference of pollutants in the marine environment are being assessed. The concentration and composition of microplastics in sediments and demersal fish stomachs are being characterized, and their potential biological effects on marine invertebrates are also being investigated
