Lignin Recovery From Hazelnut Shells, Özcan Gezen, Aleyna Fi̇li̇zfi̇danoğlu, Çağlar Özgener, İrem Deni̇z
Turkish Journal of Agriculture and Forestry
The main goal of this work was to study alkaline pretreatment of hazelnut shells (HSs) by utilization of NaOH and Ca(OH)2 with or without glycerol. The highest lignin recovery was obtained for NaOH-glycerol-pretreated HSs. This research also determined the efficiency of enzymatic hydrolysis where xylanase and cellulase were added to the pretreated residue. The highest amount of lignin of 63.2% was achieved when NaOH was used with glycerol in the pretreatment process. These findings revealed that the NaOH-catalyzed glycerol pretreatment applied in this study has great capability to be used in industrial applications.

Turkish Journal of Agriculture and Forestry
Climate change is the major factor that affects crop yield and productivity in the long term. The changing climate scenario is now impacting farmers’ lands and their outcomes in both developed and developing countries. The intercropping of crop species or varieties that have high arable capability is a promising technique for increasing crop production without increasing agricultural inputs. In intercropping, the selection of varieties, optimum sowing time, method of plant arrangement, and sowing proportion are required to make the design suitable for an intercropping system. Intercropping is one of the most highlighted agronomic practices helping to improve soil health (structure, …

A plum pox virus (PPV) susceptible traditional cultivar (Besztercei Bt.2) and a clone of a PPV resistant autochthonous landrace, Nemtudom (Nábrád) of the hexaploid European plum (Prunus domestica) were used to identify and characterize an isoform of the eukaryotic translation initiation factor, eIF(iso)4E, a host susceptibility factor required for PPV infection in plum. The cDNA and intron sequences of the eIF(iso)4E gene and the modeled 3D structure of the encoded proteins revealed sequence alterations that are not expected to critically influence the structure and function of the protein. The introns shared the canonical GT–AG splice sites, although they showed base …

Turkish Journal of Agriculture and Forestry
Heat stress (HS) is expected to become a significant abiotic stressor with the continued rise in global temperatures, severely limiting the development and production of bell pepper (Capsicum annuum L.), especially in arid and semiarid regions. Thus, this study looked into the impact of HS on the antioxidant activity, as well as the biochemical responses of bell pepper seedlings under varying temperatures (40, 32, and 25 °C) for 5 days. The results showed that exposure to higher temperatures led to an increase in enzymatic and antioxidant processes. At 40 and 32 °C, HS led to a decrease in chlorophyll a …

Turkish Journal of Electrical Engineering and Computer Sciences
High-dimensional feature vectors entail computational cost and computational complexity. However, a successful classification can be obtained with an optimally sized feature vector consisting of distinctive features. With the widespread use of the internet and mobile devices, the need for systems with low computational costs is increasing day by day. In this study, starting from the idea that each motor imagery is represented as a subject-specific pattern in the brain, we propose a new and practical method that can generate a low-dimensional feature vector based on wavelet transform.

Lsav: Lightweight Source Address Validation In Sdn To Counteract Ip Spoofing-Based Ddos Attacks, Ali̇ Karakoç, Fati̇h Alagöz
Turkish Journal of Electrical Engineering and Computer Sciences
In this paper, we propose a design to detect and prevent IP spoofing-based distributed denial of service (DDoS) attacks on software-defined networks (SDNs). DDoS attacks are still one of the significant problems for internet service providers (ISPs) and individual users. These attacks can disrupt customer services by targeting the availability of the system, and in some cases, they can completely shut down the target infrastructure. Protecting the system against DDoS attacks is therefore crucial for ensuring the reliability and availability of internet services. To address this problem, we propose a lightweight source address validation (LSAV) framework that leverages the flexibility …

Turkish Journal of Electrical Engineering and Computer Sciences
Stance detection has garnered considerable attention from researchers due to its broad range of applications, including fact-checking and social computing. While state-of-the-art stance detection models are usually based on supervised machine learning methods, their effectiveness is heavily reliant on the quality of training data. This problem is more prevalent in stance detection task because the stance of a text is intimately tied to the target under consideration. While numerous datasets exist for stance detection, determining their suitability for a specific target can be challenging. In this work, we focus on Turkish stance detection and explore the impact of training data …

Machine Learning Based Bioinformatics Analysis Of Intron Usage Alterations And Metabolic Regulation In Adipose Browning, Hamza Umut Karakurt, Pinar Pi̇r
Turkish Journal of Electrical Engineering and Computer Sciences
Adipose tissue is the major energy depot of the body and is considered an endocrine organ. Adipose tissue involves many different cell types, first and foremost, the adipocytes. White adipose cells that store fat and brown adipocytes that take part in lipid oxidation and heat generation are the most common cell types in adipose tissue. Even though brown adipocytes which have a high number of mitochondria and high fat-burning capacity are rare in adults, they are abundant in newborns and rodents. White adipocytes can gain a temporal brown-like character with a process called browning, which can be induced with cold …

A Novel Computing Scheme Based On Pattern Matching For Identification Of Nephron Loss And Chronic Kidney Disease Stage, Rehan Ahmad, Basant Mohanty
Turkish Journal of Electrical Engineering and Computer Sciences
Nephrons are the basic filtering units of the kidneys. Progression of chronic kidney disease (CKD) destroys nephrons permanently. Although there are many computing schemes suggested in recent years to identify CKD stages, no computing method has been suggested for identifying the nephron loss within kidney regions during CKD progression. In this paper, a novel pattern matching-based computation scheme is proposed to detect nephron loss in the kidney regions during CKD progression. We consider image registration (IR) with different transforms and a structural similarity index algorithm (SSIM) to match patterns of ultrasound images of kidney regions to identify the nephron loss. …

Fuzzycsampling: A Hybrid Fuzzy C-Means Clustering Sampling Strategy For Imbalanced Datasets, Abdullah Maraş, Çi̇ğdem Erol
Turkish Journal of Electrical Engineering and Computer Sciences
Classification model with imbalanced datasets is recently one of the most researched areas in machine learning applications since they induce to the emergence of low-performing machine learning models. The imbalanced datasets occur if target variables have an uneven number of examples in a dataset. The most prevalent solutions to imbalanced datasets can be categorized as data preprocessing, ensemble techniques, and cost-sensitive learning. In this article, we propose a new hybrid approach for binary classification, named FuzzyCSampling, which aims to increase model performance by ensembling fuzzy c-means clustering and data sampling solutions.
