Cambios en los parámetros de calidad del aceite de semillas de Cephalaria syriaca L. tras un proceso de refinación
The present study has determined that the crude-oil refining process from the Cephalaria syriaca (CS) seed, which could be a new vegetable oilseed source, changed its physical and chemical quality properties (except specific gravity and refractive index). It was also determined that the dominant saturated and unsaturated fatty acids in the crude and refined oils were myristic (21.06-11.80%), palmitic (10.8-8.91%), stearic (2.26-2.70%), oleic (29.17-34.24%) and linoleic (35.56-40.57%). The vitamin E values of the crude and refined CS seed oils were 51.95-50.90 mg/kg, respectively. The oxidative stability values for crude and refined CS seed oils were 2.32-2.69 h, respectively. β-sitosterol and campesterol were the predominant sterols. As a result of the refining process, although magnesium, potassium, iron and copper decreased, the ratios of sodium, aluminum, calcium, chromium, strontium, rubidium, and barium increased. The results provide preliminary data for the future consumption of CS oil in particular for refined CS seed oil.El presente estudio ha determinado que el proceso de refinación de aceite crudo de la semilla de Cephalaria syriaca (CS), que podría ser una nueva fuente de oleaginosas vegetales, modificó sus propiedades de calidad física y química (excepto la gravedad específica y el índice de refracción). También se determinó que los ácidos grasos saturados e insaturados dominantes en los aceites crudos y refinados eran mirístico (21,06-11,80%), palmítico (10,8-8,91%), esteárico (2,26-2,70%), oleico (29,17-34,24%), y linoleico (35,56-40,57%). Los valores de vitamina E de los aceites de semillas CS crudos y refinados fueron 51,95-50,90 mg/kg, respectivamente. Los valores de estabilidad oxidativa de los aceites de semilla CS crudos y refinados fueron de 2,32-2,69 h, respectivamente. El β-sitosterol y el campesterol fueron los esteroles predominantes. Como resultado del proceso de refinación, aunque disminuyeron el magnesio, potasio, hierro y cobre, aumentaron las proporciones de sodio, aluminio, calcio, cromo, estroncio, rubidio y bario. Los resultados proporcionan datos preliminares para el consumo futuro de aceite CS, en particular como aceite de semilla CS refinado
The Role of Corporate Social Responsibility in Online Identity Construction: An Analysis of turkey's Banking Sector
Cataloged from PDF version of article.This study focuses on Turkey's banking sector and investigates the role of public relations and corporate social responsibility practices in constructing organizational identities through a thematic content analysis of banks' corporate websites. Based on social identity theory, the research reveals that regardless of its core business function, an organization must communicate non-economic social concerns to construct a public identity and gain legitimacy.

On some first-order differential subordination
AbstractLet A denote the class of functions f that are analytic in the unit disc D and normalized by f(0)=f′(0)−1=0. In this paper, we investigate the class of functions such that Re{f′(z)+zf″(z)-β}>α in D. We determine conditions for α and β under which the function f is univalent, close-to-convex, and convex. To obtain this, we first estimate ∣Arg{f′(z)}∣ which improves the earlier results
Disorder induced critical phenomena in magnetically glassy Cu-Al-Mn alloys
Measurements of magnetic hysteresis loops in Cu-Al-Mn alloys of different Mn
content at low temperatures are presented. The loops are smooth and continuous
above a certain temperature, but exhibit a magnetization discontinuity below
that temperature. Scaling analysis suggest that this system displays a disorder
induced phase transition line. Measurements allow to determine the critical
exponents and in agreement
with those reported recently [Berger et al., Phys. Rev. Lett. {\bf 85}, 4176
