Ultrasound assisted choline chloride-based deep eutectic solvent extraction of bioactive compounds from salsify (Tragopogon buphthalmoides (DC.) boiss. Var. Latifolius Boiss.): A Box-Behnken design approach for
No full textThis study aimed to investigate the ultrasound -assisted extraction of bioactive compounds from salsify using deep eutectic solvents (DESs) with different molar ratios. For this reason, total phenolic (TPC), total flavonoid (TFC) compounds, and antioxidant activities (1,1-diphenyl-2-picrilhydrazyl radical scavenging activity (DPPH center dot), and ferric reducing antioxidant power (FRAP)) of extracts prepared with DES were investigated with an experimental design and optimization study conducted for this purpose. An extraction time of 40.15 min was determined as the optimal condition. Under these conditions, a molar ratio of 3:1 (acetic acid:choline chloride) and a water ratio of 42.17 % provided the highest phenolic/flavonoid compounds and antioxidant activity. Correlations between water ratio, molar ratio, and sonication extraction time were determined using principal component analysis (PCA). In conditions where TPC, FRAP, and DPPH center dot were high according to PCA, it can be concluded that the extraction time, water ratio, and molar ratio are at high levels; contrarily, TFC is at a low level. In conclusion, ultrasound -assisted extraction using DES proved effective for salsify. Therefore, choline chloride -based DESs, can be recommended as environmentally friendly green solvents and an alternative to organic solvents for the extraction of bioactive compounds from salsify
Investigation of the Effects of Filling Speed, Casting Temperature and Metallurgical Quality on Fluidity of Lamellar Graphite Cast Iron at Different Section Thicknesses
No full textIn this study, the fluidity properties of the alloy were investigated at different casting temperatures, different section thicknesses, and varying casting parameters of lamellar graphite cast iron materials. To achieve our goal, we utilized sand molds that were created with specific parameters including pouring temperature, metallurgical quality, section thickness, and fluidity test model. These molds were used for casting. Thus, the effect of fluidity properties in changing casting conditions and liquid metal advance distances at determined section thicknesses was investigated. Modeling was carried out with FlowCast casting simulation software by determining the liquid metal advance distance depending on the section thickness in the castings made in sand molds under changing casting conditions. The fluidity and advance distance of the liquid metal was determined comparatively with experimental and modeling techniques under the changing casting conditions in the parameters determined in this study. When the outcomes were examined; it was observed that different liquid metal advance distances occur at different cross-section thicknesses depending on the changing conditions.Bayburt UniversityNo Statement Availabl
Recruiting grape-isolated antagonistic yeasts for the sustainable bio-management of Botrytis cinerea on grapes
No full textBotrytis cinerea is the causative agent of grey mould disease in grapes, which was linked to significant postharvest losses. This study examined three grape-isolated yeasts (Metschnikowia aff. fructicola, Metschnikowia pulcherrima, and Hansenispora uvarum) through in vitro and in vivo tests on detached grape berries against grey mould, as well as the elucidation of their possible mechanisms of action. The antifungal mechanism of action of yeasts was determined by the lytic enzyme activity, inhibition of spore germination, biofilm activity, iron depletion, diffusible metabolites, wound-site colonisation, mycocin, and volatile organic compounds (VOCs) production. The highest in vitro efficacy (83.13%) was observed on M. aff. fructicola, followed by M. pulcherrima (82.10%) and H. uvarum (71.66%). Metschnikowia yeasts exhibited comparable enzyme activities, including protease, beta-1,3 glucanase, gelatinase chitinase, and cellulase, while H. uvarum had a poor enzymatic activity with chitinase and gelatinase. M. aff. fructicola showed relatively higher iron depletion activity than M. pulcherrima, while M. pulcherrima outperformed via diffusible metabolites. All yeast cultures significantly reduced spore germination by at least 86%. Overall, M. aff. fructicola exhibited the highest biocontrol activity with its iron depletion, inhibition of conidial germination, biofilm formation, VOCs, and well colonisation on grape berries. M. aff. fructicola 1-UDM outperformed all other yeasts by significantly reducing disease incidence and lesion diameter values (93.4% and 94.3%, respectively). Remarkably, H. uvarum VOCs demonstrated potential as a biofumigant for suppressing grey mould. All yeasts are well adapted to their ecological niche to bio-protect grapes from grey mould disease.This work was financially supported by the Scientific Research Council of Istanbul Technical University under the grant number of MDK-2018-40878.

SELÇUKLU DÖNEMİ İRAN’INDA ARAPÇA YAZAN MÜELLİFLER
No full textOn birinci yüzyılda İran coğrafyası Selçuklu hâkimiyetine girmiş, İslâmî dönem içerisinde kültür, sanat ve edebiyat açısından parlak dönemlerinden birini yaşamıştır. Selçuklu devlet adamlarının desteği ile Fars edebiyatının yanı sıra Arapça ve Arap edebiyatı da gelişim göstermiştir. İslamiyet’in yaygınlaşması ve Arapların İran’ı fethetmesi ile Arapça da siyasi bağlamda kendini göstermiş, Arapların İran topraklarına göç etmesi ile hızlanmıştır. Arap dilinin İran topraklarında yaygınlaşması, İran lehçeleri üzerinde daha çok sarayda kullanılan Pehlevice’nin üzerinde etki bırakmış hatta onu gölgede bırakmıştır. Siyasi ve divani konularda Arapçanın zorunlu hale gelmesi, Arapça kelimelerin de dile girmesine yol açmıştır. İslam kültüründe dini ve edebi ilimlerin Arapçaya çevrilmesi ve İran’da eğitim merkezlerinin açılması, Arap dilinin İranlılar arasında giderek yaygınlaşmasını sağlamıştır. Pehlevice’den Arapçaya çeviri yoluyla başlayan dil çalışmaları, şiir nazmetme ve dilbilim çalışmaları ile ortaya çıkmış, saray idaresinin desteği ile de hız kazanmıştır. Bu çerçevede Arapça ve Farsça bir milletin edebi, kültürel ve günlük hayatında ortak bir dili haline gelmiştir. İran halkı Arapça ile tanıştıktan sonra Farsça ve Arapça kelimeleri birleştirmiş iki dili tek bir potada harmanlamışlardır. Hatta bazı kelimeleri olduğu gibi alıp kendi dillerine yansıtmışlardır. Selçuklu İranı’nda, Arapça söz söyleyen büyük şair ve yazarlar ortaya çıkmış, Arap edebiyatı İran’da yükselişe geçmiştir. Bu durumda dini ve siyasi otoriterler içerisinde belli bir konuma ulaşmak isteyen kişiler, bu dili öğrenmek, yazışma ve konuşmada bu dili kullanmak zorunda olduklarını fark etmişlerdir. Arapça nazım ve nesir yazanlar, sultanların yanında ve hizmetinde büyük ikram ve iltifat görmüşlerdir. Özellikle bu dönemde müelliflerin eserlerinde Arapçayı tercih etmelerinin en önemli nedenlerinden biri kültürel etkileşimin yanında Arapçanın edebî sanatlar açısından daha hazır oluşu ve daha yerleşmiş anlatım tarzına sahip oluşudur. Ayrıca bu dönemde nesir konularında dinî, ilmî ve edebî alanlarda çeşitlilik meydana gelmiş, bu da İranlı müelliflerin dikkatini cezbetmiştir. Zira Arap ve İran topraklarında mensur çalışmalar Arap müelliflerden önce İran asıllı müellifler tarafından kaleme alınmış, tercüme hareketleri ile Arapçaya kazandırılmıştır. Örneğin Arap nesrinin gelişimi konusunda hem Pehleviceyi hem Arapçayı iyi bilen Ibn Mukaffa’nın ve Arapça risale yazan ve bu türü yeniden düzenleyen Yahyâ el-Kâtib’in adı zikredilebilir. Söz konusu bu 8.yy ediplerin yanında Selçuklu döneminde de ünlü Arapça yazarlar bulunmaktadır. Kübrevî tarikatının lideri büyük âlim Seyfüddîn el-Bâharzî, dil ve edebiyat âlimi Hâtib-i Tebrizî, saray kâtibi ve şecere âlimi Tuğrâî, tarihçi, şair ve yine soy bilimci Ebîverdî, ünlü Selçuklu vezirlerinden Enûşirvan b. Hâlid İran asıllı Arapça eserler kaleme alan müellifler arasında bulunmaktadır. Çalışmada, Selçuklu dönemi İran coğrafyasında Arapçanın tercih edilme nedenleri ele alınıp İran’da Arapça eserler kaleme alan ve Arapça yazılan eserleri şerh eden İranlı müellifler incelenecektir

Digital Writing in Foreign Language Teaching: Learner Views
No full textThe present study explores Turkish learners' approaches toward digital writing and how digital writing contributes to their language learning. For this purpose, we recruited 21 international students from 16 countries, 10 males and 11 females, who attended B2C1 -level Turkish language classes at the Akdeniz University Turkish Language Teaching Center in the 2021-2022 academic year. We recorded and transcribed the data collected through face-to-face interviews with a semi -structured interview form consisting of 6 questions. The data were then coded to generate themes, and the findings were grounded on the interpretation of these themes. Accordingly, the results uncovered that all participants engage in digital writing and mostly utilize WhatsApp, Instagram, Telegram, YouTube, and Twitter as digital writing platforms. Moreover, they were found to usually mind proper spelling and punctuation and tend to use the T9 typing system in digital writing in Turkish. We also discovered that participants find auto -correction useful and sometimes misspell vowels, consonants, and longer words/consecutive suffixes due to differences between spoken and written languages. They particularly thought that digital writing contribute to their learning of Turkish. Overall, we comprehensively discussed the findings and raised some recommendations for future research

Effects of Recycled Asphalt Material and Natural Pozzolan as Additives of Hot-Mix Asphalt: A Field Study
No full textUsing existing resources more efficiently and effectively becomes important currently. The question of how to make the best use of resources arises in the choice between constructing new roads and improving deteriorated existing roads. It is also important to reduce the amount of consumption and cost of materials. This has emerged the need to use waste materials by recycling and reusing. In this study, a new hot-mix asphalt (HMA) mixture was developed using recycled asphalt pavement (RAP), which was obtained by excavating the surface of a road at the end of its service life, together with a waste material namely natural pozzolan (NP). The final obtained mixture was used as a wear layer on an active highway. Core specimens were extracted from the paved layer for one year and subjected to dynamic and mechanical laboratory tests. Adding NP improved the resistance of the HMA mixture under heavy seasonal effects and traffic loads. In addition, NP increased the tensile strength, making the HMA mixture more resistant to deformation than control and RAP HMA mixtures. Dynamic creep test results showed that the control asphalt mixture had the most deformation and that the RAP mixture with NP had the least. According to the laboratory results, NP addition increased the stability value of the control mixture by 40%. Especially in cold seasons, the role of NP was more evident. In the performance tests that were applied on core samples taken from the field, ITS values for September increased by 98%, and the deformation values obtained as a result of the dynamic creep test decreased by 12%. In summary, adding NP to RAP HMA improves the performance of the pavement and the cost-effectiveness of the environmentally friendly use of RAP in HMA
