Exergy analysis of wine production: Red wine production process as a case study
(Elsevier Ltd, 2017) Mahmut Genç; Seda Genc; Yekta Göksungur; Goksungur, Yekta; Genc, Mahmut; Genc, Seda
This paper performs exergy analysis of a red wine production line and defines the exergy destruction rates to assess the system performance in terms of sustainability. A model study with necessary data is chosen for the calculations. The total exergy destruction rate of the overall system was determined to be 344.08 kW while the greatest destruction rate of the exergy in the whole system occurred in the open fermenter (333.6 kW). The system thermal efficiency was obtained to be 57.2% while the exergy efficiency was calculated as 41.8%. The total exergy destruction rate of the overall system increases with the increase both in the grape flow rate and the reference temperature when the reference pressure is assumed as 101.325 kPa. Furthermore the chemical exergy of streams was found much higher than the physical exergy for each stream. The exergy results were illustrated through the Grassmann diagram. Furthermore cumulative exergy loss and specific exergy loss values were determined as 2692.51 kW/1 kg/s grape processed and 5080.20 kW/kg wine respectively. © 2018 Elsevier B.V. All rights reserved.

Mediterranean Diet adherence in emerging adults in Izmir
(EMERALD GROUP PUBLISHING LTD, 2019) Mahmut Genc; Seda Genc; Genc, Mahmut; Genc, Seda
Purpose The purpose of this paper is to evaluate the adherence and abandonment of the Turkish emerging adults in an Izmir University located at western Mediterranean coast of Turkey and to assess potential associations with anthropometric characteristics. Design/methodology/approach A cross-sectional survey (n=494 18-27 years) carried out in 2017 among emerging adults in University. KIDMED Index was used to assess the degree of adherence Mediterranean Diet (MedDiet). The associations of KIDMED scores with demographic residency and anthropometric were separately reported. The data were collected through standardized questionnaires directly from participants. Findings The average KIDMED score was calculated 4.862.5. Optimum adherence to the MedDiet was found only in 13.0 percent of participants whereas 32.6 percent had poor adherence levels. Considering self-reported anthropometric data the BMI values of the population was calculated as 22.3 +/- 3.9kg/m(2). In population 13.9 percent of the subjects were underweight while 16.0 percent were overweight and 3.9 percent obese. A significant association was found between BMI and KIDMED scores both in genders and residency. Originality/value This is the first study reporting the level of adherence to the MedDiet among Turkish emerging adults in terms of residency during education and the first KIDMED study conducted in Izmir located at Aegean Sea. The results support previously proposed transition concept by several scholar from different Mediterranean countries: it was found that only 13 percent of young adults having desired dietary habits in an Aegean city with local traditional cuisine highly affected by Cretan cuisine. These results are significant for University managements and health authorities in order to take actions for returning this transition contrariwise beginning with these groups.
