Mixing processes in hydrothermal spring systems and implications for interpreting geochemical data: a case study in the Cappadocia region of Turkey

WOS: 000330720400002Mixing is a dominant hydrogeological process in the hydrothermal spring system in the Cappadocia region of Turkey. All springs emerge along faults, which have the potential to transmit waters rapidly from great depths. However, mixing with shallow meteoric waters within the flow system results in uncertainty in the interpretation of geochemical results. The chemical compositions of cold and warm springs and geothermal waters are varied, but overall there is a trend from Ca-HCO3 dominated to Na-Cl dominated. There is little difference in the seasonal ionic compositions of the hot springs, suggesting the waters are sourced from a well-mixed reservoir. Based on delta O-18 and delta H-2 concentrations, all waters are of meteoric origin with evidence of temperature equilibration with carbonate rocks and evaporation. Seasonal isotopic variability indicates that only a small proportion of late spring and summer precipitation forms recharge and that fresh meteoric waters move rapidly into the flow system and mix with thermal waters at depth. H-3 and percent modern carbon (pmC) values reflect progressively longer groundwater pathways from cold to geothermal waters; however, mixing processes and the very high dissolved inorganic carbon (DIC) of the water samples preclude the use of either isotope to gain any insight on actual groundwater ages.Scientific and Technical Research Council of Turkey (TUBITAK) [CAYDAG-104Y197]; TUBITAKThis study was funded by The Scientific and Technical Research Council of Turkey (TUBITAK; Grant No. CAYDAG-104Y197).

Hydrothermal gasification of Rosa Damascena residues: Gaseous and aqueous yields

WOS: 000330747200019The gasification of Rosa Damascena residues - by-products of the rose-oil industry - was investigated under hydrothermal conditions at 500 degrees C and 600 degrees C, 35-45 MPa pressure with a reaction time of 1 h. The experiments were performed in the absence and presence of catalysts of K2CO3 and trona in a batch type reactor. The composition of the gaseous and aqueous products was determined by gas chromatography and high performance liquid chromatography, respectively. H-2, CO2 and CH4 are the main gaseous products while carboxylic acids (formic acid, acetic acid, glycolic acid) are the main components found in the aqueous phase followed by furfurals, phenols, aldehyde and ketones. More gaseous products were obtained at the higher temperature of 600 degrees C. Adding catalyst was found to aid the conversion process but the effect was only slight. Rosa Damascena residues have the potential to be a useful source for H-2 production in the future. (C) 2013 Elsevier B.V.

Competency Gap Identification Through Customized I4.0 Education Scale

21st International Symposium on Production Research (ISPR) - Digitizing Production System -- OCT 07-09, 2021 -- ELECTR NETWORKThe key competencies and knowledge of employees in a new era of production systems based on the concept of Industry 4.0 are becoming increasingly important for business and education worldwide. The intensive interaction of intelligent production systems and people in the context of Industry 4.0 is the future of an agile, flexible, environmentally friendly, safe and efficient working environment. The key to this lies in the education and training of people in such advanced production systems. One of the most important prerequisites for companies to be successful in Industry 4.0 implementation and sustain their competitiveness and innovation is to have a skilled workforce aligned with Industry 4.0. In order to provide this prerequisite, it is necessary to determine what the competencies required for Industry 4.0 in businesses are, identify the competency gaps, and create custom education plans to close these deficiencies. From this point of view, the CEP I4.0 project funded under the Erasmus+ Programme aims to provide a customized training plan to close Industry 4.0 competitiveness gaps in order to support competitiveness and innovation in companies. This paper presents the need analysis that has been carried out based on the data collected from the participants from Turkey and Austria so far, with the details of the open-ended questions directed to the participants and analysis findings. Moreover, the main and sub-dimensions of the Industry 4.0 competence scale being developed are also presented.EU Commission [2019-1-TR01-KA202-077366]Soc Prod Res,TU WienThis study partially presents the research conducted for the project: `CEPI4.0: A Customized Education Plan Based on Industry 4.0 Competency Gaps' (ProjectIdentifier: 2019-1-TR01-KA202-077366) funded by EU Commission within the ERASMUS+ Programme (KA202 -Strategic Partnership for Vocational Education and Training)
