Abdullah Erdal TÜMER

The aim of this research is to predict league rankings through various machine learning models using technical and physical parameters. This study followed a longitudinal observational analytical design. The SENTIO Sports optical tracking system was used to measure the physical demands and technical practices of the players in all matches. Then, the data regarding the last three seasons of the Turkish Super League (2015-2016, 2016-2017, and 2017-2018), was collected. In this research, league rankings were estimated using three machine learning methods: Artificial Neural Networks (ANN), Radial ...Более

The Scientific Environment in the Period When Ibn Lahi'a (d. 174/790) Lived İbn Lehî‘a’nın (ö. 174/790) Yaşadığı Dönemde İlmî Muhit

Bekir TATLI

In this article we will focus on a famous rawī, named Ibn Lahīʿa. It is possible to find Ibn Lahīʿa, whose lineage is mentioned as ʿAbd Allah ibn Lahīʿa b. ʿUqba al-Miṣrī, frequently in early jarḥ-taʿdīl sources and muṣannaf works. But, especially from the view of ḥāadīth narrations and rijāl criticism, he is often mentioned negatively. For example, among the statements about his jarḥ-taʿdīl status, we find such expressions as “He is ḍaʻīf (weak).”, “He is ḍaʻīf al-ḥadīth.”, “His ḥadīths do not qualify to be used as evidence.”, “He is not qawī.” or similar expressions which have become widespr ...Более

Ultrasound-assisted photocatalytic decomposition of rifadin with biochar and CNT-based NiCr layered double hydroxides

Mehmet KOBYA

Modification of layered double hydroxides (LDHs) is known to be beneficial for boosting the consistent formation of reactive oxygen species (ROSs) and enhancing the photocatalytic process. Herein, a facile synthesis method for preparing carbon nanotube (CNT) and biochar (BC)-based NiCr LDH (NC) nanocomposites as a sonophotocatalyst for the efficient degradation of rifadin (RA) was provided. The formation of thin nanosheet structures of NC along with porous and nanotube structures of BC and CNT was well approved by scanning electron microscope (SEM) and high-resolution transmission electron mic ...Более

A techno-economical assessment of treatment by coagulation-flocculation with aluminum and iron-bases coagulants of landfill leachate membrane concentrates

Mehmet KOBYA

Landfill leachate treatment involved with the membrane bioreactor (MBR) combined with membrane treatment via nanofiltration (NF) and/or reverse osmosis (RO) is widely used in Turkey. This treatment produces landfill leachate membrane concentrates (LLMCs) with an undesirably high concentration of contaminants. In the study, two different nanofiltration concentrates of leachate were coagulated. Coagulant dosages from 0.10 to 5.0 g of Me3/L (Me3: Al3 or Fe3), and the pH values ranged from 4.0 to 8.0 and 3.0-9.0 for Al-based and Fe-based coagulants, respectively. The most efficient pH values were ...Более

The Impact of Government Effectiveness on Trade and Financial Openness: The Generalized Quantile Panel Regression Approach

Sezer KAHYAOĞLU

Purpose: This paper aims to investigate the impact of government effectiveness on trade and financial openness in 35 selected countries around the globe. Design/methodology/approach: A quantitative research approach was applied in the study using the generalized quantile panel regression approach to analyze the impact of identified variables in these selected countries. Panel quantile models with high estimation performance are preferred in the presence of excessive deviations and in cases where the normal distribution is invalid. Findings/results: The empirical findings indicate that selected ...Более

Mixed Bacteriological Isolation Percentages from the Uterus of Cows Slaughtered due to Infertility

Ali RIŞVANLI

Background: Intrauterine mixed infections are an important problem in cattle breeding. In this study, we aimed to determine the mixed bacteriological isolation rates from the uterus of cows with clinical metritis and to reveal the relationships between the bacteria that isolated together.Methods: For this purpose, sterile swabs were taken from 490 uterus obtained from cattle slaughtered due to infertility in three slaughterhouses and used them to perform microbiological tests. After evaluating the data, it was determined that the bacterial isolation rate from uterus with clinical metritis was ...Более

Perfluorooctanoic acid (PFOA) removal from real landfill leachate wastewater and simulated soil leachate by electrochemical oxidation process

Mehmet KOBYA

Poly and perfluoroalkyl compounds (PFASs) are a group of chemicals that are widely used and are difficult to purify. Within this group, perfluorooctanoic acid (PFOA), known for its highly polar and strong carbon-fluorine bonds, is a frequently encountered species in surface water, drinking water, and groundwater. In this study, we investigated the efficiency of electrooxidation (EO) in PFOA removal, optimization of EO parameters, and groundwater simulation in a realistic scenario. The EO optimization experiments were performed with a boron-doped diamond (BDD) anode for different values of pH, ...Более

Effect of somatic cell count on milk composition and some chemical properties of milk

Ali RIŞVANLI

Subclinical mastitis is a very important disease for dairy cattle farms. As a result of the deterioration of milk quality, it causes economic losses in enterprises. Milk samples of 180 cows were divided into five groups according to the somatic cell count. Some chemical properties and composition were measured in milk samples. The ratio of solid-non-fat, mineral matter, lactose, and protein decreased as the somatic cell count of the milk increased (P < 0.05). No statistical difference was observed between the fat content of milk and the level of somatic cell count (P > 0.05). Although specific ...Более

ON OPTIMAL CONTROL OF THE INITIAL VELOCITY OF AN EULER-BERNOULLI BEAM SYSTEM

Ercan ÇELİK

In this study, we consider an optimal control problem for an Euler-Bernoulli beam equation. The initial velocity of the system is given by the control function. We give sufficient conditions for the existence of a unique solution of the hyperbolic system and prove that the optimal solution for the considered optimal control problem is exists and unique. After obtaining the Frechet derivative of the cost functional via an adjoint problem, we also give an iteration algorithm for the numerical solution of the problem by using the Gradient method. Finally, we furnish some numerical examples to dem ...Более
