Therefore, determination of cultivation area is still a hot topic among researchers from various disciplines, planners, and decision makers. In present study, it was aimed to evaluate performances of three classifications algorithms among most widely used ones, namely, maximum likelihood (ML), random forest (RF), and k-nearest neighborhood (KNN), for paddy rice mapping in a mixed cultivation area located in Biga District of Çanakkale Province, Turkey. Visual, near-infrared and shortwave infrared bands of Landsat 9 acquired in dry season of 2022 year was utilized. The classification scheme included six classes as dense vegetation (D), sparse vegetation (S), agricultural field (A), water surface (W), residential area – base soil (RB), and paddy rice (PR). The performances were tested using the same training samples and accuracy control points. The reliability of each classification was evaluated through accuracy assessments considering 150 equalized randomized control points. Accordingly, RF algorithym could identify PR areas with over 96.0% accuracy, and it was followed by KNN with 92.0%.","PeriodicalId":489750,"journal":{"name":"Türk doğa ve fen dergisi","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135476962","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}

Çalışma üç aşamada gerçekleştirilmiştir. İlk aşamada Türkiye/Eskişehir/Kırka bölgesinden temin edilen bor atığı kullanılarak silika aerojel üretimi yapılmıştır. İkinci aşamada, üretilen silika aerojel hacimce farklı oranlarda (%0 (REF), %15 (AB1), %25 (AB2), %35 (AB3), %45 (AB4)) tuğla bünyesine ikame edilmiş, 900 oC ve 1000 oC pişirilerek katkılı tuğla numuneleri üretilmiştir. Üçüncü ve son aşamada ise, üretilen numunelere basınç dayanımı ve ısı iletim katsayısı tayini deneyleri uygulanmıştır. Ayrıca numunelerin içyapısının incelenmesi amacıyla SEM görüntüleri alınmıştır. Sonuç olarak; her iki sıcaklıkta da aerojel miktarının artması ile basınç dayanımı ve ısı iletim katsayısı değerinde azalma meydana gelmiştir. SEM görüntülerinde silika aerojel miktarının artmasıyla amorf yapının artığı ve yer yer boşluklar ve çatlaklar oluştuğu görülmüştür. Ayrıca basınç dayanımı baz alındığında; üretilen numunelerden AB1 numunesi taşıyıcı olarak kullanılabileceği, AB2, AB3 ve AB4 numunelerinin ise kaplama veya geleneksel yapılarda duvar dolgu malzemesi olarak kullanılabileceği tespit edilmiştir. Bor atığı gibi silis içeren atıkların aerojel üretiminde kullanılmaları atıkların bertaraf edilmesi için uygun bir çözüm yolu olacağı düşünülmektedir.","PeriodicalId":489750,"journal":{"name":"Türk doğa ve fen dergisi","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135580056","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}

A general literature search for one of the electronegative metals, zinc, revealed serious deviations in corrosion results. In order to understand the reasons behind these deviations, zinc metal was investigated at macro and micro levels during and after the Tafel corrosion analysis. In-situ macro surface investigation during the OCP period and Tafel analysis were performed, and it was found that the zinc surface undergoes proceeding corrosion attack following the immersion in 3.5 wt.% NaCl solution. In-situ macro surface analysis exhibited that the pre-oxidation of the surface proceeds as nonuniform at local regions. SEM-EDS and XRD analysis proved that the particular crystal planes of the zinc form ZnO with increasing immersion time. A linear sweep voltammetry (LSV) technique was applied to detect the oxygen removal and starting hydrogen evolution potentials. Three identical Tafel experiments were performed on samples without any treatment, and another three consecutive Tafel experiments were performed on the samples which applied pre-reduction potential. Obtained results revealed that in-situ pre-applied reduction potential just before the Tafel analysis cleaned the surface and allowed uniform oxide formation, resulting in the lowest standard deviation of the calculated Tafel elements.","PeriodicalId":489750,"journal":{"name":"Türk doğa ve fen dergisi","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135537630","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}

In this study, it was aimed to determine the effects of TQ on testicular toxicity in rats with experimental Alzheimer's disease. In the study, 33 Wistar Albino rats weighing 190-230 gr were used. Rats were 11 rats in each group; were divided into 3 equal groups as control, ALZ and ALZ+TQ. The control group was given saline by IP route for 28 days daily. The ALZ group was given 60 mg/kg D-gal + 40 mg/kg AlCl3 IP for 28 days daily. The ALZ+TQ group was given 60 mg/kg D-gal + 40mg/kg AlCl3 for 28 days by IP + 20 mg/kg TQ by oral gavage for last 14 days daily. According to the findings of our study, a decrease in SOD, CAT, GPx activity and GSH levels and an increase in MDA levels were determined in the ALZ group. In the ALZ+TQ group, while SOD, GPx, CAT activities and GSH levels increased, MDA levels decreased. Semen analyzes showed that there was a decrease in sperm motility and sperm density in the ALZ group, and an increase in the rate of abnormal sperm and dead spermatozoa. In the ALZ+TQ group, sperm motility, abnormal sperm rate and dead spermatozon rate improved. As a result, it was determined that the decrease in semen quality and increase in oxidative stress induced by AlCl3+D-Gal were suppressed by TQ, protecting the testicular tissue from oxidative damage and increasing semen quality.","PeriodicalId":489750,"journal":{"name":"Türk doğa ve fen dergisi","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135580055","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}

In our study, the effects of barley, wheat and oat grass juices grown in hydroponic conditions on the seed physiology of medicinal and aromatic plants were investigated. Medicinal and aromatic plant seeds placed in petri dishes were germinated in vitro. 10 ml of water (control), barley grass juice, wheatgrass juice and oat grass juice were applied to the seeds. The experiment was carried out according to the randomized plots factorial design. In the experiment, 140 petri dishes were used and the germination physiology and root and stem lengths of the seeds were determined.
