The biochemical contents and antioxidant activities of four tanacetum L. taxa
Get PDFThe goal of the present study is to determine some of the biochemical compositions and antioxidant capacities of plant extracts in two endemic taxa for Turkey including T. cadmeum (Boiss.) Heywood subsp. orientale Grierson and T. nitens (Boiss. & Noë) Grierson together with T. polycephalum (L.) Sch.Bip subsp. argyrophyllum (K. Koch) Podlech, and T. parthenium (L.) Sch.Bip. The fatty acids were determined by using gas chromatography, while phenolics, lipid soluble vitamins and sterols were determined by using HPLC and radical scavenging activities, total phenolics, and FRAP were determined spectrophotometrically. It was found that Tanacetum taxa have palmitic acid (C16:0), and stearic acid (C18:0) as major saturated fatty acids and linoleic acid (C18:2 n6), α-linolenic acid (C18:3 n3) and oleic acid (C18:1 n9) as principal unsaturated fatty acids. It was found that Tanacetum taxa had more total unsaturated fatty acid contents (60.24±0.3%- 70.54±0.29%) than saturated fatty acids and it was found that T. parthenium had the highest total essential fatty acid composition (58.65%±0.59%). It was also reported that the omega6/omega3 ratio of T. cadmium subsp. orientale (8.22) differed from other taxa in this study. Also, the present study showed that Tanacetum had the lowest amount of lipid soluble vitamins. On the other hand, catechin was found to be the main polyphenolic compound in this study and it was determined that T. parthenium had the highest catechin (4479.1±5.71 µg/mg) and total phenolic contents (324.91±2.01 µgGAE/mg) in this study. Rutin was only determined in two endemic taxa T. cadmeum subsp. orientale (23±0.91 µg/mg), and T. nitens (5.7±0.27 µg/mg). Also, the naringenin, vanillic acid and caffeic acid amounts of the endemic T. cadmeum subsp. orientale and T. nitens were higher than other taxa in the study. In addition, it was determined that Tanacetum taxa had a high stigmasterol content. However, T. parthenium had a higher ergosterol content (271±2.36 µg/mg). It was also found that T. parthenium has highest D2, α-tocopherol, retinol acetate, ergosterol, and stigmasterol contents among the studied taxa. In addition, the study showed that Tanacetum taxa have strong DPPH and ABTS radical scavenging activities. It was concluded that Tanacetum taxa have potent antioxidant capacity

Tourist Experiences of Guided Culinary Tours: The Case of Istanbul
No full textThe aim of this study is to investigate the culinary experiences of tourists visiting Istanbul, Turkey. This study adopted a qualitative case study method utilizing user-generated content by analyzing travelers’ comments on one of the most popular travel websites. The data was collected between 30 May and 28 June 2019 from travelers’ reviews. The findings show that culinary tour experiences are heterogeneous based on dimensions of guide, food characteristics (taste, variety, flexibility, and availability), educational experience, authentic experience, memorable experience, value/price, socialize/meet people, safety, the hospitality of locals, and satisfaction, recommendation, and revisit intentions. Since there are no previous empirical studies on the culinary tour experience of tourists in the existing literature, it is believed that this study provides a significant contribution to the current knowledge. Moreover, from a managerial perspective, this study provides an in-depth understanding of the culinary tour experience in tourist destinations

Traditional uses of wild plants in Mardin central district and attached villages (Turkey)
Get PDFThis research reveals traditional uses of wild plants found in Artuklu district in Mardin Province in the Southeastern Anatolia Region of Turkey. This study, conducted between 2017 and 2019, gathered information on the medicinal and other uses of plant species traditionally used in Artuklu and the local names of these plants. Face to face surveys were conducted with 183 people in 91 neighbourhoods. The ethnobotanical uses of 125 plants belonging to 35 families, which are traditionally underutilized by the local people, have been recorded. Our results showed that the highest Relative Frequency of Citation (RFC) was recorded for the species Lathyrus pseudocicera Pamp. (0.32). 1 taxon is from Stereocaulaceae of Fungi, 2 taxa are from Pteridophyta and the others 122 taxa are from Magnoliophyta. In the region, plants mostly belonging to the families Fabaceae (21 taxa), Lamiaceae (11 taxa), Asteraceae (10 taxa) and Brassicaceae (10 taxa) were determined. The recorded ethnobotanical uses are for: food (64), medicinal (40), fodder (12), children's toys (5) and various other purposes (4). Due to the fact that Turkish, Kurdish, Arabic and Assyrian people have lived together in the Artuklu district, this ethnic diversity increased the use of wild plants and added richness. Preserving the coexistence of different cultural and religious groups in the research zone is essential for the maintenance of the rich wild plant local heritage
Gastronomy tourism through tea and coffee: travellers’ museum experience
No full textPurpose: The main aim of the present research is to investigate the tea and coffee experience of travellers around the world and clutch the dimensions of tea and coffee museum experience. Design/methodology/approach: Travellers who had experienced tea and coffee museums were purposefully selected as a sample group for the study. As tea and coffee museums that are benefiting from user-generated content (UGC) are limited, a qualitative multiple case study method has been chosen to enrich more comments and obtain more data. For the data gathering, as a UGC platform, TripAdvisor was benefited. Findings: According to an inductive content analysis of reviews, the model of dimensions of tea and coffee museum experience that consist of nine main categories revealed: educational experience, authentic experience, memorable experience, participatory experience, shopping experience, atmosphere, facilities, employees and tour guides and negative experiences (negative staff attitudes and skills, lack of foreign language explanations and cleanliness). Originality/value: To the best of the authors’ knowledge, this study is the first to examine the tea and coffee museum experience of travellers around the world. It contributes to the gastronomy literature by providing the dimensions of the tea and coffee museum experience
Utilization of Morchella esculenta-mediated green synthesis golden nanoparticles in biomedicine applications
No full textThis study aimed to synthesize gold nanoparticles (AuNPs) by hot water extract in room conditions using edible Morchella esculenta (ME) and investigate the bioactive properties of the synthesized Morchella esculenta-based gold nanoparticles (ME-AuNPs). The characterization of the biologically synthesized ME-AuNPs was made using the ultraviolet–visible spectrophotometry, X-ray crystallography, scanning electron microscopy, Fourier transforms infrared spectroscopy, and energy dispersive X-ray spectrum methods. The ME-AuNPs, with a particle size of 16.51 nm, were found to have strong bioactive properties. The antioxidant activity of the ME-AuNPs attempted by metal chelating activity, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity and the β-carotene linoleate model system. The activities at 10 mg/mL were 82, 85, and 77% for the chelation of ferrous ions, DPPH scavenging, and β-carotene linoleate tests, respectively. The ME-AuNPs also showed strong antimicrobial activity against various pathogen microorganisms and strong cytotoxic activity in the A549 and HepG2 cell lines. This study demonstrated the possibility of using a cheap and nontoxic fungal extract as a reducing and stabilizing agent for the synthesis of size-controlled, large-scale, and biocompatible AuNPs that could be used in future diagnostic and therapeutic applications
Why anthropology? An evaluation on activist anthropology
Get PDF2020 yılının başından itibaren tüm dünyayı etkisi altına alan COVID-19salgını ve salgın yöntemi ekolojik yıkım, iklim krizi, yoksulluk ile yerleşikeşitsizlik gibi mevcut birçok sorunu daha da görünür hale getirdi.Bu yazı da antropolojinin bu mevcut sorunların çözümüne nasıl katkısağlayabileceği üzerine düşünerek, aktivist antropoloji yaklaşımını konuedinmektedir. Bu bağlamda yazı konuyu üç aşamada ele almaktadır. İlkolarak disiplinin sınırlarına ilişkin genel bir değerlendirme yapılmaktadır.Bu değerlendirme aktivizm ile antropoloji arasındaki keskin ayrımdanhareket etmektedir. İkinci olarak ise toplumsal sorunların çözümüneyönelik antropoloji yaklaşımını ifade eden uygulamalı antropolojiyaklaşımı ele alınmaktadır. Uygulamalı antropolojinin ele alınmasındakiamaç, aralarındaki benzerlik ve farklılıkları yoluyla aktivist antropolojininanalizine zemin hazırlamaktadır. Nihayet, aktivist antropoloji incelenerekantropolojiyi kamusal bir ses ve sorumluluğa, dahası bir mücadele alanıhaline dönüştürme imkânın ortaya konması hedeflenmektedirSince the beginning of 2020, COVID-19 pandemic has been affecting the whole world. The pandemic and its governance have been creating many problems such as ecological devastation, climate crisis, poverty and entrenched inequality more visible. Thinking about the question of how anthropology could contribute to the solution of these current problems, this paper scrutinizes activist anthropology. In this context this paper proceeds through three broad topics. In the first topic, a general evaluation is made on the limit of anthropology. This evaluation depends upon a strong distinction between anthropology and activism. Secondly, applied anthropology as a social problemsolving- oriented anthropological approach is discussed. The objective of discussing applied anthropology is to provide a basis for analyzing activist anthropology through similarities and differences between them. Finally, activist anthropology is examined. By this way, this paper aims at revealing the opportunity to turn anthropology into a public voice and responsibility, moreover a into a field of struggle
Nitrate and Nitrite Levels of Potable Water in Mardin, Turkey
Get PDFIn this study, it was aimed to investigate the presence and levels of nitrate and nitrite in potable water in Mardin. A total of 118 water samples, collected from 64 taps, 41 wells and 13 water tanks within the city center and districts of Mardin, were used in this study. The nitrate and nitrite analyses were performed by spectrophotometric method. The mean value of nitrate levels was found as 2.55±3.58 ppm in 31 (26.27%) and nitrite as 0.032±0.091 ppm in 91 of 118 water samples. The mean values of nitrate and nitrite were 2.49±3.65 ppm and 0.033±0.072 ppm in taps; 2.00±3.09 ppm and 0.035±0.125 ppm in wells; 3.93±4.71 ppm and 0.018±0.017 ppm in tank water respectively. One (0.85%) of analyzed water samples had nitrite level (0.72 ppm) higher than maximum legal limit. There was no statistically significant difference between the samples taken from taps, wells and water tanks for presence of nitrate and nitrite.According to the results of the study, although a general risk was not determined in terms of nitrate and nitrite levels in the water in Mardin, it is thought that monitoring is important for the detection of individual contaminations
Türkiye’de Yaşlanma, Gelir ve CO2 Emisyonu İlişkisi Üzerine Bir Uygulama
No full textSosyal ilerleme -insan refahındaki iyileşme- daha yüksek ekonomik çıktı
düzeylerine bağlıdır ve daha yüksek ekonomik çıktı, tüm doğal kaynaklar - toprak,
ormanlar, yer altı suları, okyanuslar ve iklim - üzerinde baskı yaratacaktır. Temel ve
yeri doldurulamaz doğal kaynakları aşındıran sürdürülemez tüketim ve üretim
kalıpları, nihayetinde ekonomik büyüme ve sosyal ilerlemenin temelini
zayıflatacaktır. Bu nedenle, daha yüksek ekonomik çıktı gerektiren sosyal ilerlemeyi
teşvik etme amacının çevrenin sürdürülebilirliğini tehlikeye atmaması önemlidir. Bu
çalışmada Türkiye’de 1980-2016 yılları arasında yaşlanma, gelir ve CO2 emisyonu
arasındaki ilişki Johansen eşbütünleşme testi ile incelenmiştir. Elde edilen bulgulara
göre yaşlanma, gelir ve CO2 emisyonu arasında tespit edilen eşbütünleşik ilişki
FMOLS gibi uzun dönem katsayı tahmincilerinin kullanılmasına olanak tanımıştır.
Bu tahminciye göre kişi başına düşen gelirdeki artış CO2 emisyonunu %0.6465
artırırken, yaşlanmadaki artışın kişi başına düşen CO2 emisyonunu %0.8468 azalttığı
görülmüştür. Ayrıca, Türkiye’de Çevresel Kuznets Eğrisi (ÇKE) hipotezini
