Fenolik bileşikler yeşil cevizden konvansiyonel yöntemle (120, 240, 360 480, 720, 960 ve 1200 dakika) ve ultrason destekli ekstraksiyon (%25, 50, 75 ve 100 genlik; 10, 20, 30, 40, 50 ve 60 dakika) ile ekstrakte edilmiştir. HPLC analizi ile yeşil ceviz ekstraktlarında bazı fenolik asitler (gallik asit, neoklorojenik asit), flavonol (rutin) ve juglon tespit edilmiştir. Konvansiyonel yöntemde toplam fenolik içerik 240 dakika sonra 158.55 mg GAE/kg olarak belirlendi. Ultrason destekli ekstraksiyonda ise toplam fenolik içerik, 60 dakika sonunda %100 genlikte 156.80 mg GAE/kg olarak ölçülmüştür.

En iyi ekstraksiyon verimi, %100 ultrason genliğinde elde edilse de 50. dakikadan sonra fenolik bileşiklerdeki kayıplar nedeniyle ekstraksiyon süresi uzatılamamakta ve uzun sürmesine karşılık bozunma olmadığı için konvansiyonel ekstraksiyonda daha yüksek fenolik bileşik değerlerine ulaşılmaktadır.","PeriodicalId":386555,"journal":{"name":"Yüzüncü Yıl Üniversitesi Fen Bilimleri Enstitüsü Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127023958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fish samples (117 individuals) were obtained between 2017-2018, and the total lengths of each fish were measured (±0.1 cm) and their weights (±0.01 g) were weighed. Ages were determined from the distal surfaces of all otoliths (asteriscus) and transversal sections were taken. Percent agreement, average percent error and coefficient of variation were calculated. In the population, total lengths ranged between 17.8-69.3 cm and weights ranged between 67.57-5 412 g. The ages read in whole and section otoliths were determined as 2-6, 2-7 in ADL and 1-8,0-7 in BFL, respectively. It is the section otolith method with the highest percent agreement (75.43% and 71.67%, respectively), the lowest mean percent error (3.89; 3.98) and coefficient of variation (5.11; 5.29) for ADL and BFL.

It was previously shown that DNA isolation could be performed from the pellet obtained after centrifugation of freeze-thawed blood (FTB), and this pretreatment had constructive results on DNA isolation. However, which centrifugation levels can be used for this pretreatment and their effects are unknown. The aim of the study was to determine appropriate centrifugation levels for this pretreatment and show their effects on isolated DNA. For this purpose DNA isolations were carried out from both pellet and supernatant obtained by centrifugation at different levels of FTB. Then, spectrophotometric, gel electrophoresis, and real-time PCR analyses were performed in the isolated DNA samples. As a result, centrifugation of FTB at 5 000 ×g for 2 min or over let genetic material to pellet completely, which enable to obtain higher DNA yield. Real-time PCR results showed that mtDNA/nDNA ratios did not change in the isolated DNA samples which were performed from pellets obtained by defined centrifugation levels whereas isolated DNA integrity decreased. To conclude, centrifugation at 5 000 ×g for 2 min or over can be used to harvest and wash genetic material found in FTB before DNA isolations.","PeriodicalId":386555,"journal":{"name":"Yüzüncü Yıl Üniversitesi Fen Bilimleri Enstitüsü Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125585970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biogas and electrical energy production amounts were calculated based on the total number of animals in Turkey. In this context, our country's biogas production from animal waste for 2021 has been determined as 15.894×106 m3/year and electrical energy production as 28.609×106 kWh/year. As a result of the calculations, it has been determined that the first three regions with the highest annual biogas amounts are the Aegean Region (3.889×106 m3/year), the Central Anatolia Region (2.701×106 m3/year) and the Mediterranean Region (2.533×106 m3/year). It has been determined that the first three regions with the highest annual electricity production amounts are Aegean Region (7.000×106 kWh/year), Central Anatolia Region (4.862×106 kWh/year) and Mediterranean Region (4.559×106 kWh/year). Considering that the total electricity consumption of our country in 2021 is 329.634×106 kWh, it has been determined that 8.67% of the annual energy need can be met by using biogas energy if there are biogas facilities in each province.","PeriodicalId":386555,"journal":{"name":"Yüzüncü Yıl Üniversitesi Fen Bilimleri Enstitüsü Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129967519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the different seismological parameters, the results of these previous studies are compiled to reveal the future earthquake hazard. In the region, many destructive earthquakes with magnitudes greater than 5.0 occurred in the instrumental and historical periods. Finally, two destructive/damaging earthquakes that occurred around the city center of Van on October 23, 2011 (Mw=7.1) and 9 November 2011 (Mw=5.8) showed that the region has active fault mechanisms with different characteristics. As a result, the earthquake hazard evaluation and earthquake forecasting in the near future show higher seismic risk in the east of Lake Van, especially around Çaldıran, Muradiye, Özalp, Saray, and Erciş than in other regions. In addition to seismic risk analyses, the evaluation of the Van Lake Basin and its surroundings, in terms of soil engineering properties and soil-structure interaction, using different parameters based on both geophysical methods and structural investigations, were also examined in this study.","PeriodicalId":386555,"journal":{"name":"Yüzüncü Yıl Üniversitesi Fen Bilimleri Enstitüsü Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125150899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
