Geochemistry and origin of ultramafic enclaves and their basanitic host rock from Kula Volcano, Turkey

2013

Abstract The Quaternary Kula Volcanic Province is located in western Anatolia, Turkey. This Na-alkaline anorogenic volcanism includes exposures of around 80 cinder cones, lava flows, and tuffs, representing one of the youngest volcanic activities in this region (1.9–0.026 Ma). The magmatism is related to an extensional regime and is interpreted as being derived predominantly from the asthenospheric mantle. The lava flows are mostly of a basanitic composition and host rare comagmatic enclaves. The enclaves are composed of two dominant lithologies: amphibolites and clinopyroxenites with and without olivine. Amphibole is usually resorbed and replaced by a rhoenite-rich breakdown corona. The mi…

Current and Potential Use of Citrus Essential Oils

2013

Since the Middle Ages, citrus essential oils (EOs) have been widely used for their bactericidal, virucidal, fungicidal, antipara- sitical, insecticidal, medicinal and cosmetic proprieties. Also nowadays, they find important applications in pharmaceutical, sanitary, cosmetic, agricultural and food industries. The best method to extract EOs from citrus plant tissue is steam distillation because of a vari- ety of extracted volatile molecules such as terpenes and terpenoids, phenol-derived aromatic components and aliphatic components. In vitro physicochemical assays classify most of them as antioxidants.

Ascorbic acid content and transcriptional profiling of genes involved in its metabolism during development of petals, leaves, and fruits of orange (C…

2021

Citrus fruit is one of the most important contributors to the ascorbic acid (AsA) intake in humans. Here, we report a comparative analysis of AsA content and transcriptional changes of genes related to its metabolism during development of petals, leaves and fruits of Valencia Late oranges (Citrus sinensis). Petals of close flowers and at anthesis contained the highest concentration of AsA. In fruits, AsA content in the flavedo reached a maximum at color break, whereas the pulp accumulated lower levels and experienced minor fluctuations during development. AsA levels in leaves were similar to those in the flavedo at breaker stage. The transcriptional profiling of AsA biosynthetic, degradatio…

Organised Crime and the Economy: a Framework for Policy Prescriptions

2014

In this paper we discuss policies to combat organised crime from the perspective of economic analysis. We introduce concepts such as supply and demand for Mafia and the implied notion of equilibrium to build a framework to classify the contexts in which organised crime interferes with the economy. We then use this framework to discuss policy interventions, distinguishing between policies implemented by the State and mobilisation of civil society. We show that using the economic approach helps understand the aspect of persistence of criminal organisations and identify vicious circles of different nature. The broad spectrum of State policies identified includes norms on competition, on the ef…

Romanian Folk Literature in Our Classes: A Proposal for the Development of Intercultural Competence

2015

Abstract The present research highlights the ways in which folk literature, this valuable tool that contributes to students’ formation from both a human and literary perspective, can promote intercultural competence in class and foster a better integration within the community, while consolidating favorable attitudes towards interculturality. We share Rodriguez Almodovar's view (2009), according to which the folk story makes the geographic space expand; it channels affectivity, while guiding the learning process towards the acceptance of social values that are representative for each culture. The objectives of our study are focused, on the one hand, on improving intercultural competence amo…

Social Emotional Learning: Implementation of Sustainability-Oriented Program in Latvia

2016

Abstract This article is focused on the description of the content and the implementation process of an originally developed, culturally appropriate and sustainable social and emotional learning program in Latvia. The article also includes the teachers’ self-reflected experience illustrated through the perspective of the program’s sample activities. The general goal of the program is to develop the emotional and social competencies of pupils, and at the same time to introduce to schoolteachers the principles necessary for combining academic and social emotional learning. As a preventive approach this program is aimed at all ages of pupils (from primary forms to secondary grades). During the…

The Importance of Positive Psychological Strengths in Well-Being and Adjustment of Romanian Emerging Adults: A Pattern and Variable-Oriented Approach

2021

Transition to adulthood in countries that have seen recent historical structural changes in society as well as changes in what it means to be an adult represents important contexts for investigations of ways in which positive development and transition to adulthood are experienced. Situated in such context, this cross-sectional study aimed to (1) describe profiles of positive psychological strengths, as measured by the Five Cs of positive youth development (PYD) and (2) document how identified profiles might differ in relation to other aspects of positive and problematic development. Participants were 272 Romanian emerging adults attending university (76% female; aged 19–29 years old, Mage …
