10XSBF Bone-Like Hydroxyapatite Coating of Ti-6Al-4V with Microwave Irradiation and its Antibacterial Properties

Mustafa DOLAZ

The surfaces of titanium (Ti-6Al-4V) implants, which are widely preferred as implant material in medicine and dentistry, are biomimetically coated with nanohydroxyapatite (nHAp) in simulated body fluid (10XSBF) with microwave-assisted 10-f time concentration solution. A second layer was formed with different amounts of non-toxic AgNO3 to impart antibacterial properties to the implant materials coated with nHAp. In comparison of uncoated implants with nHAp and Ag-coated Ti-6Al-4V implants, surface morphologies were evaluated by SEM analysis, phase grade and structure were evaluated by XRD, and ...Дагы

Mustafa DOLAZ

Two new Schiff bases ligands (HL1 and HL2) and their Co2, Mn2, Fe3, Ru3, Cr3, and VO2 complexes were synthesized and characterized by FT-IR, 1H-NMR, and Mass spect. and analytical methods. A single-crystal X-ray diffraction study determined the molecular structure of HL1. The catalytic effects of metal complexes on benzyl alcohol and potato starch (PS) oxidation were compared in an H-2O-2 medium. The percent conversion of benzyl alcohol to benzaldehyde and benzoic acid was determined by Gas Chromatography. [Co(L-1)(2)], [Mn(L-1)(2)], [Co(L-2)(2)], and [Mn(L-2)(2)] showed the highest catalytic ...Дагы

Migrant parents and psychosocial effects of parents' absence on children left behind in the Kyrgyz Republic

Gülşat MUHAMETJANOVA

This study was conducted to investigate the psychosocial effects of parents' absence on children left behind in the Kyrgyz Republic (Kyrgyzstan). A survey was conducted in 2018 with a sample of 457 secondary school children aged 11-18-years-old in the Kyrgyz Republic. The results of multiple linear regression analysis showed that the psychological well-being of children was not significantly influenced when their parents were not divorced but did live separately. However, children with parents who lived abroad and were divorced did show a significant increase in their psychological distress wh ...Дагы

Natural Products/Bioactive Compounds as a Source of Anticancer Drugs

Fatih Ramazan İSTANBULLUGİL

Simple Summary Cancer is considered as a large group of diseases involving abnormal cell growth, which results in an alarming rise in the mortality rate at the worldwide level. Presently, the main point of interest in pharmaceutical research is the development of the novel and efficient anticancer drugs based on natural sources. In this regard, plants, and some microbial species, due to their composition, ecology, phytochemical, and ethnopharmacological properties, play a significant role. Accordingly, a series of plant-derived bioactive compounds are in the clinical development phase against ...Дагы

Benzotiyofen@Pd as an efficient and stable catalyst for the electrocatalytic oxidation of hydrazine

Hilal DEMİR KIVRAK

An efficient methods for the synthesis of 2-(2,5-dimethylphenyl)-3-iodobenzo[b]thiophene (4) is described, and investigated its anode catalyst performance by using electrochemical methods (CV, CA and EIS). When 2-(2,5dimethylphenyl)-3-iodobenzo[b]thiophene (4) is applied, the specific activity is found as 25.811 mA/cm(2). Interestingly, when Palladium (Pd) is electrochemically deposited on the benzothiophene derivative, the catalytic activity increased the 80.930 mA/cm(2). This result is highest than the current metal based anode catalyst. Moreover, EIS and CA measurements display that Pd dope ...Дагы

Correlation and sequential path analysis of oil yield and related characteristics in camelina under seasonal variations

Hossein ZEİNALZADEH TABRİZİ

The objectives of the current study were to determine the usefulness of sequential path analysis in camelina to obtain information about the relationship between yield and yield components and to evaluate their relative importance in camelina oil yield under summer and winter cultivation. A split-plot design, with two varieties as the main plot and four sowing times as the subplot, was carried out over two growing seasons (2017-2019) in Samsun, Turkey. Sequential path analysis revealed that, as first-order predictors, grain yield and oil content displayed the most significant and positive dire ...Дагы

Transient event classification using pmu data with deep learning techniques and synthetically supported training-set

Özgül SALOR-DURNA

This paper presents a research work which focuses on generating synthetic data to enrich the training-set of a deep learning (DL) based classification system to classify power system transient events using PMU frequency measurements. The synthetically improved training-set is shown to increase the classification performance compared to the case when only the actual-data training-set is used. The proposed classification system helps to reveal high-frequency transient variation information out of PMU measurements collected at a relatively much lower rate, especially when a small set of training- ...Дагы

Curved beam generation and its experimental realization by rectangular prism with asymmetric polynomial back surface

Mirbek TURDUEV

With the discovery of self-accelerating beams, possibility of obtaining curved light beams in free space has been realized. These special beams paved the way for many new applications as well as the exploration of novel beam types. Recently, great research effort has been conducted to realize different types of curved beams such as photonic hook and airy beam. These curved types of beams are obtained by introducing structural asymmetry or applying non-uniform dielectric distribution to the input and output face of the structure. With this regard, we propose specially designed asymmetric struct ...Дагы

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 ...Дагы

Water is an effective additive to fuel oil to reduce the concentration of soot in the gas phase

Mirlan MOLDOBAYEV | Kubat KEMELOV | Zarlık MAYMEKOV

Soot is one of the products of incomplete combustion of hydrocarbon fuels. It has the property of adsorption of active and carcinogenic substances on the surface of soot particles. In this regard, in burner equipment of medium and small power, it is required to develop and implement effective environmental measures to reduce emissions of soot particles. In this paper, the fuel oil-water-air system at a wide temperature range (T500-3000K) was studied and the ratio of gas-liquid flows (water content in fuel oil 5-15) at the maximum entropy of the system and the formation of soot in flue gases wa ...Дагы
