    The effect of microwave roasting process on the compositional parameters and bioactive contents of fig seed oil were investigated. Fig seeds were ground and roasted in a microwave oven at 350, 460 and 600 Watt for 5 and 10 minutes and the roasted seeds were processed to obtain oil. The results showed that peroxide, K232 and K270 values were adversely affected by roasting. Fig seed oil was a prosperous source of γ-tocopherol and significant losses were observed due to microwave pre-treatment. The major fatty acids in fig seed oil were linolenic, linoleic and oleic acids; whereas the major triacylglycerols were LnLO, LnLnL, LnLnLn and LnLnO, according to fatty acid profile. The most abundant sterol in the fig seed oil samples was β-sitosterol with 3235.90 to 3625.62 mg/kg, followed by Δ5- and Δ7-avenasterols. The principal component analysis and agglomerative hierarchial clustering served to differentiate between intense and mild microwave-treated oils as well as the unroasted samples.Se investigó el efecto del proceso de tostado por microondas sobre los parámetros de composición y contenido bioactivo del aceite de semilla de higo. Las semillas de higo se molieron y tostaron en un horno de microondas a 350, 460 y 600 vatios durante 5 y 10 minutos a continuación se obtuvo el aceite. Los resultados han demostrado que los valores de peróxido, K232 y K270 se vieron afectados negativamente por el tostado. El aceite de semilla de higo es una buena fuente de γ-tocoferol y se observaron pérdidas significativas mediante el pretratamiento con microondas. Los principales ácidos grasos del aceite de semilla de higo fueron los ácidos linolénico, linoleico y oleico; mientras que los principales triacilgliceroles fueron LnLO, LnLnL, LnLnLn y LnLnO que ratificaron el perfil de ácidos grasos. El esterol más abundante de las muestras de aceite de semilla de higo fue el β-sitosterol que varió de 3235,90 a 3625,62 mg/kg, acompañado de Δ5-avenasterol y Δ7-avenasterol. El análisis de componentes principales y la agrupación jerárquica aglomerativa permitieron la diferenciación de aceites tratados con microondas intensos y suaves, así como las muestras sin tostar

    Purpose – The purpose of the study is to examine the relationship between the COVID-19 pandemic and international student mobility from an alternative perspective and to reveal descriptive findings. Design/methodology/approach – This study follows qualitative research methodology. In accordance with the purpose of the study, the data were collected by the literature review and then it was analyzed by the descriptive analysis method. The effect of the COVID-19 pandemic on international student mobility and the relationships between these variables are explained by tables and classifications. Findings – According to the findings obtained, the restrictions in physical student mobility and shutdown are observed as the biggest challenges that occurred in higher education during the COVID-19. On a global scope, international student mobility has experienced a major break. Physical campus life is still on standby. Online higher education does not give any campus life as before. Students cannot benefit form city's or country's facilities when studying online at home country. The collaboration between university and business has been declined and this is even more discouraging for international students. The hybrid education model produced an intermediate solution in this period. On the other hand, the rise of online education has created new techniques for higher education. University students who cannot go abroad attend different countries lectures and education programs. But also a new challenge has come as the access of online platforms in under developing countries university students. Online education system also discussed in terms of creating inequality in higher education. Research limitations/implications – This study focused on student mobility and not focused about academic mobility. Practical implications – It is seen that the traditional higher education system has been adapted into online distance higher education system since COVID-19 crises began globally. On the other side, it is observed that most of studies have focused the effect of COVID-19 on university students based on the transition to online education. When considering the effect of pandemic process on the mobility of international students and higher education, the authors can suggest policy makers to develop new higher education protocols and teaching models supporting key issues (economic, social, health, education and equalization) in the long-term. Higher education institutes have been able to produce creative and innovative solutions for both education and communication during the pandemic process. Social implications – University students who cannot go abroad attend different countries lectures and education programs. But also a new challenge has come as the access of online platforms in under developing countries university students. Online education system also discussed in terms of creating inequality in higher education. Originality/value – This study provides a new perspective for international student mobility in the context of COVID-19 pandemic. This is an emerging issue for the literature. This study is original with its approach to the subject from a global perspective through reviewing the studies of different countries. This study points out key variables for determining the effect of COVID-19 on international student mobility for future studies. When employing quantitative research models, the current key variables can guide them

    How Dangerous is the Counterparty Risk of OTC Derivatives in Turkey?

    Get PDF
    Recent developments in Turkish derivatives markets demonstrate the increasing importance of risk management not only for individual banks but also for the entire system. In this context, this study analyzes the counterparty credit risk of OTC derivatives. The analysis is based on a hypothetical portfolio that is characterized by key aspects of the instruments banks hold. Thus, the portfolio consists of vanilla swaps, which dominate banks’ transactions. By simulating market risk factors, we come up with proxy risk exposure figures for the whole banking system. After a proper adjustment, these figures have been compared with the risk weighted assets, which includes credit risk,as well as with the capital. Consequently, we observe that the counterparty credit risk resulting from the use of OTC derivatives is relatively small for the Turkish banking system. Nevertheless, in light of the new regulatory framework introduced by Basel III, the importance of credit and market liquidity risk for the OTC instruments in trading portfolios is expected to increase in the near future

    Get PDF
    Digital transformation in higher education, especially after COVID-19 is inevitable. This research explores digital transformation maturity and challenges post COVID-19. The significance of the study does not only stem from the critical role of higher education in building the workforce and knowledge economy. This study triangulates the findings of multiple research instruments, including survey, interviews, case study, and direct observation. The research findings show a significant variance between the respondents’ perception of digital transformations maturity levels, and the core requirements of digital transformation maturity. The findings also show the lack of holistic vision, digital transformation competency, and data structure and processing as the leading challenges of digital transformation

    Moving beyond European and Latin American Typologies:The Peculiarities of AKP’s Populism in Turkey

    Get PDF
    Despite the growing literature on Turkish populism, there is yet no consensus on how best to categorise the Justice and Development Party (Adalet ve Kalkınma Partisi or AKP). This article argues that this lack of consensus is due to a selective focus on the attributes of AKP’s populism. Indeed, when the party’s features are examined holistically, it does not neatly conform to the dominant typologies of populism, which were conceived mostly for European and Latin American examples. For historical reasons, AKP’s populist discourse defines “the people” versus “the elite” in civilisational terms and combines this with strategies of neo-liberalism, strong party organisation and grassroots mobilisation. This blend of populism distinguishes the AKP case from the exclusionary/inclusionary and classical/neo-liberal/radical typologies previously identified by the literature. However, the Bharatiya Janata Party in India and the Thai Rak Thai Party in Thailand have similar attributes to the AKP, drawing attention to the need to move beyond the existing ideological and strategic approaches to populism and towards a more comprehensive socio-cultural approach. The article contributes to the literature on populism by highlighting possible avenues for further research based on such a comprehensive understanding of populism based also on cases from Asia

    Objectives The effect of gender on anatomic structures and various body systems were illustrated in the literature. The purpose of this study was to identify the influence of gender and tooth loss on incisive canal characteristics and buccal bone dimensions in the anterior maxilla. Materials and methods Computed tomographies ( CTs ) of 417 male and 516 female patients in four dental clinics were included in this study. The diameter and the length of the incisive canal; width and the length of the bone anterior to the canal; palatal bone length, root length, and root width of the central incisor teeth were measured and recorded from CT sections. Results Mean incisive canal length was 11.96 ± 2.73 mm and 10.39 ± 2.47 mm in men and women, respectively, ( P  < 0.05). In men, mean canal diameter was 2.79 ± 0.94 mm whereas in women it was 2.43 ± 0.85 mm and this difference was statistically significant ( P  < 0.05). Men had significant higher buccal bone dimensions (length and width of the bone anterior to the canal) than women. Absence of teeth in the anterior maxilla decreased incisive canal length and buccal bone dimensions; however, canal diameter remain unchanged. Conclusions Present results suggested a gender related differences in anatomic features of incisive canal and surrounding buccal bone. In addition, crestal canal diameter, buccal bone length, and thickness parameters might be different in distinct countries.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/99051/1/clr2493.pd

    Transpiration rate of chickpea wild accessions and cultivars in Turkey

    Chickpea (Cicer arietinum L.), like most cultivated crops, has exceedingly narrow genetic and phenotypic diversity. Thus breeding with only cultivated germplasm will have steeply diminishing returns, raising an urgent need for new sources of diversity. The focus of the research was to assess a representative set of newly collected wild accessions of C. reticulatum and C. echinospermum, for drought adaptation traits, i.e. transpiration rate (TR) response to increasing VPD and to soil drying. These experiments were conducted during the spring season (18 March to 21 April 2016) at the Dicle University glasshouse. The experimental design was a complete randomised block design with six replications. Measurements were conducted in late April during vegetative growth and VPD changed from 2.13 to 4.35 kPa. To measure TR, potted plants were weighed at regular time intervals over the course of an entire day, and therefore, under increasing VPD. At the end of the experiment total leaf area was destructively measured, along with shoot, root and leaf dry weights. There was a 2.31-fold range of variation in the transpiration response among genotypes. The wild genotypes Sirnak and Deste had extreme TR values exceeding cultivated check cultivars, and several wild genotypes had only a moderate increase in TR under increasing VPD. These moderate TR responses provide germplasm sources with a potential to limit water losses under high evaporative demand, akin to a protection mechanism, especially under dry environments or in future climates. These screenings, therefore, open an exciting opportunity for breeding cultivars with enhanced performance under harsh climates
