This study aimed to determine the chemical properties (fatty acid composition,oil content, sterol and tocopherol compositions) of the oils extracted from theseeds of safflower (Dinçer, Remzibey, Balci, Linas, Yenice, Olas) varieties har-vested in different periods from flowering to ripening period. In parallel with theincrease of harvest time, the humidity rate decreased, while the oil ratiosincreased. It was determined that palmitic (16:0) and stearic (18:0) acids, whichare significant saturated fatty acids, and oleic (18:1) and linoleic (18:2) acids,which are unsaturated fatty acids, are quite high in the oils of all safflower varie-ties. These fatty acids showed significant changes from the first harvest to thelast harvest. The total saturated fatty acid ratios decreased, while the amountof unsaturated fatty acids increased as the maturation progressed. The firstand latest harvest samples of Dinçer, Remzibey, Balcı, Linas, Yenice, Olas cul-tivars were selected and their sterol and tocopherol compositions were exam-ined. The highest level of sterol in all cultivars wasβ-sitosterol and the amountof sterols decreased towards full maturity. It was determined thatα-tocopherolwas the dominant tocopherol found in the safflower oils and the amount oftocopherol increased towards full maturity.

Grape juice is a widely consumed fruit due to its bioactive compounds, minerals, and aroma components. Our objective was to investigate ultrasound treatment of black grape juice affects its bioactive components due to using response surface methodology (RSM) and artificial neural network (ANN) optimization. At the same time, mineral components, sugar components, organic acids, and volatile aroma profiles were compared in black grape juice treated with thermal and ultrasound pasteurization. ANN showed superior predictive values (>99%) to RSM. Optimal combinations were obtained at 40 ◦C, 12 min, and 65% amplitude for thermosonication. Under these conditions, phenolic, flavonoid, antioxidant activity, and anthocyanin values were 822.80 mg GAE/L, 97.50 mg CE/L, 24.51 mmol Trolox/L, and 368, 81 mg of mv-3-glu/L, respectively. Thermosonicated grape juice (TT-BGJ) was tested against black grape juice (P-BGJ) produced with conventional thermal methods. This study investigated the effects of thermal pasteurization and thermosonication on black grape juice bioactive compounds and minerals, aroma profile, and sensory evaluation. Thermosonication affected the aroma profile less, 329.98 μg/kg (P-BGJ) and 495.31 μg/kg (TT-BGJ). TT-BGJ was detected to contain seven different mineral elements (Mn, K, Fe, Mg, Cu, Zn, and Na). Thermosonication caused an increase in Fe, Zn, Mn, and K minerals. Panelists generally liked the TT-BGJ sample. These results suggest that the thermosonication process may potentially replace the traditional black grape juice processing thermal process.

Kendisini “annesinin rahmindeyken tanrı tarafından seçilip görevlendirilen kişi” (Gal. 1: 15-16) olarak tanımlayan ve tebliğ ettiği mesajın/öğretinin “Mesih İncili” olduğunu vurgulayan Aziz Pavlus, Hıristiyanlığın en önemli şahsiyetlerinden birisidir. Dolayısıyla onunla ilgili yapılan ya da yapılacak olan çalışmalar, Hıristiyan inanç ve ritüellerinin daha iyi anlaşılıp kavranmasını sağlayacaktır. Zira Aziz Pavlus’un öğretileri Hıristiyan geleneğinin temelini oluşturmuş, onun inanç ve düşünceleri çerçevesinde gelişip şekillenmiştir.
2014-01-01T00:00:00ZCovid-19 Pandemi Döneminde Türkiye Döviz Piyasasında Balon Var mı? GSADF Testinden Kanıtlarhttps://hdl.handle.net/11491/83352022-02-23T13:35:17Z2021-01-01T00:00:00ZCovid-19 Pandemi Döneminde Türkiye Döviz Piyasasında Balon Var mı? GSADF Testinden Kanıtlar
Finansal bir varlığın fiyatının temel değerinden sapması veya rasyonel kabul edilmeyen varlık fiyatlarındaki hızlı ve sürekli artışlar, finansal piyasalarda fiyat balonu kavramını ifade eder. Fiyat balonları, büyük ölçüde varlığın oynak yapısından, bilgi asimetrisinden, davranışsal finansın bir konusu olan sürü davranışından, ekonominin kırılgan yapısından ve/veya piyasanın kendi dinamiklerinden kaynaklanmaktadır. Varlık fiyatlarında oluşan balon belirli bir süre sonra patlamakta ve bu durum piyasada paniğe, reel ekonomide ciddi tahribatlara ve hatta finansal krizlere neden olmaktadır. Bu nedenle varlık fiyatlarındaki balonların varlığının tespit edilmesi, nedenlerinin ve sıklığının araştırılması, piyasanın paydaşları tarafından son derece önemlidir. Çalışmanın amacı, Covid-19 döneminde Türkiye döviz piyasasında oluşan spekülatif fiyat balonu varlığını GSADF testi ile araştırmaktır. Bu bağlamda çalışmada, USD/TL ve EURO/TL için 13.03.2020-08.10.2021 dönemi haftalık veriler kullanılmıştır. Çalışmanın analiz sonuçları doğrultusunda, Covid-19 döneminde Dolar kurunda altı, Euro kurunda ise sekiz fiyat balonu tespit edilmiştir. Döviz kurunda fiyat balonlarının görüldüğü tarih itibariyle, iç ve dış piyasalarda yaşanan ekonomik ve politik olaylara karşı oldukça duyarlı olduğu söylenebilir. Bu nedenle kanun koyucuların Türkiye döviz kuru piyasasında istikrarlı sağlayacak politikalar geliştirmesi gerekmektedir.; The deviation of the price of a financial asset from its fundamental value or the rapid and continuous increases in the prices of assets that are not considered rational express the concept of a price bubble in financial markets. Price bubbles are primarily due to asset volatility, information asymmetry, herd behavior, which is a topic of behavioral economics, the fragile structure of the economy, and/or the dynamics of the market itself. The bubble in asset prices bursts after a certain period of time, causing panic in the market, severe damage to the real economy, and even financial crises. For this reason, the detection of bubbles in asset prices is of most importance to the market participant. The aim of the study is to investigate the existence of a speculative price bubble in the Turkish foreign exchange market during the Covid-19 period with the GSADF test. In this regard, using weekly data for the period between March 13, 2020 and Oct 08, 2021 were used for USD/TRY and EURO/TRY. The results show that six price bubbles in the dollar exchange rate and eight price bubbles in the euro exchange rate were during the Covid-19 period. As of the date of the price bubbles seen in the exchange rates, it can be said that it is very sensitive to the economic and political events in the domestic and foreign markets. For this reason, the legislators must develop policies to ensure the stability of the Turkish foreign exchange market.
