Araştırmamızda, kanserojen etkisi de bilinen boyar maddelerden biri olan kristal viyoletin sulu çözeltilerden Siirt/Koçpınar kili ile uzaklaştırılması çalışıldı. Birinci aşamada kil modifikasyona maruz bırakılmadan doğal şekliyle (KO) kullanıldı, ikinci aşamada ise aynı işlemler HNO3 ile aktifleştirilen Siirt/Koçpınar kili (KA) ile tekrar edildi. Adsorpsiyon neticesinde veriler D-R, Langmuir ve Freundlich izoterm modellerine uygulandı. Hesaplamalar sonucunda en iyi verim, 0.4 g adsorbent dozajı ile pH 5 ortamında elde edildi. Çalışma neticesinde optimum koşullarda KO adsorbenti için % 59.48, KA adsorbentin de % 83.97 giderim sağlandı. Korelasyon katsayısının 0.99’dan büyük olarak hesaplandığı Freundlich izoterm modeli, çalışmamızın uygun olduğu izoterm modeli oldu. Ayrıca D-R izoterm modeli için bulunan D-R adsorpsiyon serbest enerjisi, hem doğal hem de aktifleştirilmiş kil için 8 kJ/mol değerinden küçük bulundu. Bu sonuç adsorpsiyon işleminin fiziksel olduğunu gösterdi. Termodinamik hesaplamalar neticesinde hesaplanan Gibbs serbest enerji değerlerinin sıfırdan küçük çıkması bizlere çalışmamızın istemli meydana geldiğini gösterdi.

The aim in this study was first to explain, in detail the conversion of diacetates over time into chlorinated monoacetates following ether cleavage with AcCl of norcantharimide derivatives with the help of the NMR technique and second, to verify this conversion theoretically and computationally. Ether cleavage reactions of N-methyl, N-benzyl, and N-acetoxyethyl-substituted norcantharimide derivatives were performed with Ac2O or AcCl in the presence of H2SO4, and the mechanisms of these reactions were elucidated in detail. According to the 1H NMR analyses of aliquots from the reactions with AcCl, trans-1,4-diacetates formed firstly. Upon the continuation of the reaction, trans-1,4-diacetates transformed into trans-1,2-chloroacetates via an SN2' mechanism. Additionally, this explanation was further supported by the soft theoretical and physical calculations.

Anonymity is one the most important problems that emerged with the increasing number of graph-based social networks. It is not straightforward to ensure anonymity by adding or removing some nodes from the graph. Therefore, a more sophisticated approach is required. The consideration of the degree of the nodes in a graph may facilitate having knowledge about specific nodes. To handle this problem, one of the prominent solutions is k-degree anonymization where some nodes involving particular degree values are anonymized by masking its information from the attackers. Our objective is to evaluate the achievement of k-degree anonymization with a well-known graph structure, namely, Barabási-Albert graph, which is similar to the graphs on social networks. Hence, we generate multiple synthetic Barabási-Albert graphs and evaluate the k-degree anonymization performance on these graphs. According to experimental results, the success of k-degree anonymity approximately proportional to the number of edges or nodes.

A new tetrakis-(2-methylpyrazino)porphyrazinato gadolinium(III) acetate complex was synthesized. Elemental analysis, Fourier-Transform Infrared, Ultraviolet-visible, and fluorescence spectroscopy techniques clarified its structure. It can dissolve very well without aggregation in both Dimethyl sulfoxide and N, N-Dimethylformamide, which have high dielectric constant and high dipole moment from polar aprotic solvent type. Its aggregation property was also investigated in dimethyl sulfoxide at different concentrations, and it was determined to contain monomeric species. In addition, its fluorescence properties were investigated in Dimethyl sulfoxide and the effect of gadolinium(III) acetate metal ion as a heavy rare earth element was determined. According to the findings in this study, it may be used as an electronic and optical material and in various technological applications such as photocatalytic applications. In addition, these findings may be useful for systems that include changes in pyrazinoporphyrazine-like forms.

This research was carried out to determine the ethnobotanical studies of edible wild plants in some parts of Mardin province, a historical city of Upper Mesopotamia, in the Southeastern Anatolia Region of Turkey, between the years 2018-2020. The wild plants consumed as food by the local people living in the villages of Mardin province and their usage patterns were determined. Face-to-face interviews were conducted with 80 people and ethnobotanical information forms were prepared. The local and scientific names of the identified plants were included and their usage purposes were determined. As a result of the study, it was determined that 131 plant species were used as edible in folk tradition.

Elde edilen güncel hızlar ile geçmiş dönemdeki hızlar arasındaki farklar incelenmiş ve bileşen bazında fark haritaları oluşturulmuştur. Fark haritaları incelendiğinde bileşen bazında farkın yüksek çıktığı değerlerin X bileşeninde 17 mm/yıl, Y bileşeninde 14 mm/yıl, Z bileşeninde ise 14 mm/yıl olduğu görülmüştür.

Bu çalışmanın amacı; tekstil endüstrisinde yaygın olarak kullanılan bir boyarmadde olan Reaktif Mavi 21 (RM21)’in atık sulardan adsorpsiyon yöntemiyle uzaklaştırılmasında kaolin yüzeyine dekore edilmiş bakır katkılı çinko oksit nanokompozitinin adsorban olarak kullanılabilirliğinin araştırılmasıdır. Adsorpsiyon üzerine, başlangıç RM21 konsantrasyonu, adsorban miktarı, sıcaklık ve denge süresi gibi çeşitli deneysel parametrelerin etkileri incelenmiştir. Adsorpsiyon hızının ikinci mertebeden hız ifadesine uyduğu ve kaolin yüzeyine dekore edilmiş bakır katkılı çinko oksit nanokompozitinin RM21 üzerine adsorpsiyonunun Redlich-Peterson izoterm modeliyle uyum sağladığı görülmüştür. Bu çalışmanın sonuçları, RM21’nin sulu çözeltilerden uzaklaştırılmasında kaolin yüzeyine dekore edilmiş bakır katkılı çinko oksit nanokompozitinin etkili bir adsorban olarak kullanılabileceğini göstermiştir.

Time series forecasting has lots of applications in various industries such as weather, business, retail and energy consumption forecasting. Accurate prediction in these applications is very important and also difficult task because of complexity and uncertainty of time series. Nowadays, using deep learning methods is a popular approach in time series forecasting and shows better performance than classical methods. However, in the literature, there are few studies which use deep learning methods in fuzzy time series (FTS) forecasting. In this study, we propose a novel FTS forecasting model which is based upon hybridization of Recurrent Neural Networks with FTS to deal with complexity and also uncertanity of these series. The proposed model utilizes Gated Recurrent Unit (GRU) to make prediction by using combination of membership values and also past value from original time series data as model input and produce real forecast value. Moreover, the proposed model can handle first order fuzzy relations as well as high order ones. In experiments, we have compared our model results with those of state-of-art methods by using two real world datasets; The Taiwan Stock Exchange Capitalization Weighted Stock Index (TAIEX) and Nikkei Stock Average. The results indicate that our model outperforms or performs similar to other methods. The proposed model is also validated by using Covid-19 active case dataset and shows better performance than Long Short-term Memory (LSTM) networks.

While artificial intelligence (AI) technologies are used in many fields such as health, education, art and continue to develop rapidly, emerging artificial intelligence solutions are also being addressed by different disciplines, such as informatics and law. Apart from the problems of legal rules' having access to the speed of social change, the search of a legal infrastructure that is suitable for keeping up with these changes has started to make itself felt in recent years. In the study, the technical stages of digital artworks created by using contentious producer networks from deep learning algorithms were discussed and evaluated within the scope of intellectual and artistic works law. In the study, 6989 abstract and portrait paintings, which are a subset of the Wiki-Art dataset, were used. As a result, it has been seen that the number of images in the dataset affects the originality of the outputs. It is thought that the proposed method can be applied to different branches of art and can give art lovers a different perspective.
