Global security in the Mediterranean
Elvira Sánchez Mateos
Revista CIDOB d'Afers Internacionals , 2002,
Abstract: In the last decade, the WEU, NATO and specially the European Union (in the framework of the Barcelona process) initiated security dialogues with countries East and South of the Mediterranean Basin. Those processes are far to achieve significant progress. Some arguments help to explain the present situation: on the one hand, European countries and organizations lack clear strategic goals and consistent policies. On the other, difficulties to create a security dialogue in the Mediterranean, which is a precondition to generateboth a common language and security culture, are the result of differences between the European and the Arab security cultures. Nevertheless, the geopolitical environment, the Euro-Mediterranean process itself and the development of the European Union demanda strategic revision on how to implement the objectives of the Barcelona Declaration, reformulating the idea of Euro-Mediterranean Partnership towards a new concept of shared security that integrates Southern interests and concerns.
Lebanon and The Syrian-Israeli Relations: an Analysis of Lebanon as a Microcosmos of The Middle East
Elvira Sánchez Mateos
Revista CIDOB d'Afers Internacionals , 1996,
Abstract: The purpose of this article is to assert that the Lebanese conflict had its origins in the domestic situation of the country, but that became acute, crossed the threshold towards open war and finally reached a stalemate due to regional politics and specifically Syrian-Israeli relations, a dynamics that determines the future of Lebanon.Furthermore, the author states that despite the relative success of the Middle East Peace Process in the Palestinian and Jordanian fronts, the eventual resolution of the Lebanese conflict is intimately linked to the Syrian-Israeli dispute on the Golan Heights,and that meaningful achievements on both issues are pre-conditions to fully normalize the relations among the Arab states and Israel.

Empleo de las formas de acusativo precedidas de se variante de le(s) en el habla de Caracas
Sánchez Doreste,Rosa Elvira;
Opción , 2008,
Abstract: the inclusion of the mark of plural studies in sequences of accusative clitics of with singular, lo/la, preceded, variant reference of, being based to them on corpus 1987 of spontaneous speech of the institute of philology at the ucv, frequent phenomenon between the american speakers of spanish and documented in numerous dialectology works. stated that in the speech of caracas, the non canonical presence is highly significant from the mark of plural in the accusative clitics with referring singular, when goes preceded of the clitics variant of the referring dativo with plural. same thusi, when a sn is duplicated with the corresponding clitics [+plur] in postverbal position in function of ci exists propensity to the use of invariable him. by such reason i consider the possibility that the referring postverbal position of plural of the variant difficult pronoun non canonical presence of the mark of plural in the accusative form with referring singular, hypothesis, that in the sample, obtains sustentation. on the other hand, it was decided to investigate the influence of the nature of the referring one of the accusative one in corpus. the results confirm that the neutral character of the referring one favors the non canonical use of the mark of plural.
Empleo de clíticos pronominales de tercera persona en el habla de Caracas

Opción , 2005,
Abstract: this study quantifies, interprets and explains some aspects of the behavior of the caracan speakers with regard to the use of third person pronominal clitics; the data is based on the1987 corpus of spontaneous speech gathered by the instituto de philology at the venezuelan centraluniversity (ucv). possible correlations of their non canonical use with different linguistic and extralinguistic variables are analyzed. among the conclusions of the study the following are highlighted: 1) when the clitical referent designated possesses an animated nature and a sexual character, the discordances between the generic and the numerical differentiated clitics have little relevance; 2) when the clitical referent designates only one single thing, number discordances between the clitic and referent are practically null; and on the contrary, when a plurality of things is designated, they are relevant, specially with the dative form when the referent is in a postverbal position; 3) the genus itself does not have a relation in the production of discordance, since anomalies are due to "ad sensum" concordances.
Empleo de clíticos pronominales de tercera persona en el habla de Caracas

Opción , 2005,
Abstract: El estudio cuantifica, interpreta y en algunos aspectos explica el comportamiento de los hablantes de la ciudad de Caracas en relación con el empleo de los clíticos pronominales de tercera persona, basándose en el corpus 1987 de habla espontánea del Instituto de Filología de la Universidad Central de Venezuela (UCV). Se analizan posibles correlaciones de sus empleos no canónicos con diferentes variables lingüísticas y extralingüísticas. Entre las conclusiones del estudio destacan: 1) Cuando el ente designado por el referente del clítico posee naturaleza animada y se le atribuye carácter sexuado, las discordancias entre los clíticos diferenciados genérica y numéricamente y sus referentes poseen escasa relevancia; 2) Cuando el referente del clítico designa un solo ente, las discordancias de número, entre clítico y referente, son prácticamente nulas; por el contrario, al designar una pluralidad de entes resultaron relevantes, especialmente con la forma de dativo cuando el referente está en posición postverbal; 3) El género no guarda propiamente relación en la producción de discordancias pues las anomalías se deben a concordancias "ad sensum".

Abstract: Se estudia la inclusión de la marca de plural en secuencias de clítico de acusativo con referencia singular, lo/la, precedidas de se, variante de les utilizando como base el corpus 1987 de habla espontánea del Instituto de Filología de la UCV , fenómeno frecuente entre los hablantes americanos del espa ol y documentado en numerosos trabajos dialectológicos. Se constató que en el habla de Caracas resulta altamente significativa la presencia no canónica de la marca de plural en el clítico acusativo con referente singular cuando va precedido de la variante clítica del dativo con referente plural. Igualmente, cuando se duplica con el clítico correspondiente un SN [+plur] en posición posverbal en función de CI existe propensión al empleo de un le invariable. Por esto se consideró la posibilidad de que la posición posverbal del referente plural del se variante pronominal dificultaría la presencia no canónica de la marca de plural en la forma acusativa con referente singular, hipótesis que en la muestra obtiene sustentación. Por otro lado, se decidió indagar la influencia de la naturaleza del referente del acusativo. Los resultados confirman que el carácter neutro del referente favorece el empleo no canónico de la marca de plural.
Mechanisms Involved in the Selective Transfer of Long Chain Polyunsaturated Fatty Acids to the Fetus
Alfonso Gil-Sánchez,Elvira Larqué
Frontiers in Genetics , 2011, DOI: 10.3389/fgene.2011.00057
Abstract: The concentration of long chain polyunsaturated fatty acid (LCPUFA) in the fetal brain increases dramatically from the third trimester until 18 months of life. Several studies have shown an association between the percentage of maternal plasma docosahexaenoic acid (DHA) during gestation and development of cognitive functions in the neonate. Since only very low levels of LCPUFA are synthesized in the fetus and placenta, their primary source for the fetus is the maternal circulation. Both in vitro and human in vivo studies using labeled fatty acids have shown preferential transfer of LCPUFA from the placenta to the fetus compared with other fatty acids, although the mechanisms involved are still uncertain. The placenta takes up circulating maternal non-esterified fatty acids (NEFA) and fatty acids released mainly by maternal lipoprotein lipase and endothelial lipase. These NEFA may enter the cell by passive diffusion or by means of membrane carrier proteins. Once in the cytosol, NEFA bind to cytosolic fatty acid-binding proteins for transfer to the fetal circulation or can be oxidized within the trophoblasts, and even re-esterified and stored in lipid droplets. Although trophoblast cells are not specialized for lipid storage, LCPUFA may up-regulate peroxisome proliferator activated receptor-γ (PPARγ) and hence the gene expression of fatty acid transport carriers, fatty acid acyl-CoA-synthetases and adipophilin or other enzymes involved in lipolysis, modifying the rate of placental transfer, and metabolism. The placental transfer of LCPUFA during pregnancy seems to be a key factor in the neurological development of the fetus. Increased knowledge of the factors that modify placental transfer of fatty acids would contribute to our understanding of this complex process.
Effects of a Cardiac Rehabilitation Program in Patients with Congenital Heart Disease  [PDF]
Nathalie Dedieu, Luis Fernández, Elvira Garrido-Lestache, Inmaculada Sánchez, Maria Jesus Lamas
Open Journal of Internal Medicine (OJIM) , 2014, DOI: 10.4236/ojim.2014.41004
Abstract: The beneficial effects of the programs of cardiac rehabilitation in adults are widely known. Nevertheless, the accomplishment of these programs in patients with congenital heart is scarcely developed. In this study, we want to evaluate the preliminary results of a program of cardiac rehabilitation. Patients and methods: Thirty-three patients aged 8 to 40 completed the rehabilitation program. Thirty-one of them had an operated congenital heart disease, one had an implantable cardioverter defibrillator, and another was a patient with arterial hypertension and obesity. Data before and after the program were compared. Results: Improvements were found in all of the measured parameters. We found a statistically significant difference in maximum heart rate, exercise duration, foreseen heart rate’s percentage and increase of metabolic equivalents. Twenty-seven of 33 patients noticed a significant improvement in their quality of life at the end of the program. Conclusion: Initial results seem to be encouraging and we consider the experience very positive since the program achieved an improvement in the functional capacity of our patients. In our opinion, these observations and the results of our study provide strong arguments for the incorporation of cardiac rehabilitation into the care of many patients with congenital heart disease.
Flat Belt Separation System under Slat in Fattening Pig Housing: Effect of Belt Slope Angle  [PDF]
Francisco Alonso, Aranzazu Mateos, Jesús Vázquez, Miguel Angel Garcimartín, Elvira Sánchez, Ismael Ovejero
Agricultural Sciences (AS) , 2018, DOI: 10.4236/as.2018.96048
Abstract: In this study, the separation and drying efficiency of the excreta, separated into solid and liquid fraction by a flat conveyor belt under a partial slatted floor in a facility for fattening pigs, was determined. Two transverse slope angles (4° and 6°) for the flat belts were used, in a trial with pigs from 20.61 to 117.83 kg of live weight (LW), and the sample size was 7 pigs per pen, 42 pigs per room. The flat belt was more efficient with 6° than with 4° slope angle (32.65% vs. 29.91% dry matter content of solid fraction during the whole fattening period, respectively; P < 0.0001). The separation and drying efficiency of the excreta, defined as the ratio of dry matter content of the solid fraction to dry matter content of fresh faeces, were significantly higher for the angle of 6° than for the 4° (1.4137 vs. 1.3030, during the whole fattening period; P < 0.0001). With a slope angle of 6°, this efficiency was not improved in finishing period -83.40 to 117.83 kg LW (two extractions per day) with regard to the growth period -20.61 to 83.40 kg LW (one extraction per day). Meanwhile, with 4° it did improved. The ventilation system underneath slat seems to play a key role in the obtained results.
