Metaphoric Conceptualization of Love Pain or Suffering in Turkish Songs through Natural Phenomena and Natural Disasters

Muhammet Fatih Adıgüzel

Traditional Turkish love is identified with suffering. This study investigates how suffering in love is metaphorically conceptualized in Turkish via natural phenom ena and disasters. Based on figurative expressions in sad love songs of Arabesque and Art music genres, the study reveals that love pain/suffering is expressed through three salient metaphors: 1) LOVE PAIN/SUFFERING IS NATURAL PHENOMENA,2)LOVE PAIN/SUFFERING IS NATURAL DISASTERS, and 3) the overarching metaphor (the suffering) LOVER’SBODYISALANDSCAPE(affected by weather conditions or natural disasters). It was unearthed from metaphoric expressions in lyrics that as part of a cultural scenario, natural phenomena anddisastersareprofiledasinternalized forces culturally imagined to directly affect vital body parts to expres...

A comparative prediction for tensile properties of ternary blended open-end rotor yarns using regression and neural network models

İlhan İlhami

This study focused on predicting tensile properties of PES/CV/PAN blended Open-End Rotor yarns. The effective factors were fiber blend ratios (six stages from 0 to 100%), linear density (three count levels), mixing method (carding machine and drawframe), and number of passages in drawframe (one and two times) as production parameters. We performed a stepwise multiple linear regression (MLR) analysis and established an artificial neural network (ANN) model that trained with backpropagation rule as Levenberg–Marquardt. Then, we conducted a comparative analysis for both models in terms of prediction performance. As a result, ANN has given a slightly better prediction values than MLR for breaking strength but significantly better prediction values for breaking elongation.

Serum zinc and alkaline phosphatase values in pediatric bone marrow transplantation patients

Zinc (Zn) plays an important role in the maintenance of immune functions, including cellular/humoral immunity, and in the prevention of oxidative injury. Therefore, the maintenance of a normal Zn status may be important in bone marrow transplantation (BMT) patients. Serum Zn levels were determined in 35 children during the BMT period. In addition, as Zn-related factors, serum Cu levels and alkaline phosphatase (AP) activity were also measured. There was a significant decrease in Zn and AP values during the immediate post-transplant period (lowest at day +7) when compared to pre-BMT levels (p < .01). The patients who developed hypozincemia were more likely to be transplanted for a diagnosis of malignant disorder and were younger, and adverse events appeared to occur more frequently. This pr...

OXIDATION OF TOLUENES TO AROMATIC ALDEHYDES WITH MOLECULAR OXYGEN IN SUBCRITICAL WATER

Recep Özen, Ahmet M. Gizir & N. Simsek Kus

Oxidations are important transformations in organic synthesis. In general, many oxidations are carried out with a large excess of chromium or manganese reagents. The metal residues are environmentally undesirable and often cause problems during work-up.2 In addition organic oxidations in the chemical industry have traditionally been performed in either aromatic or halogenated solvents.' One of the most attractive oxidants is molecular oxygen? since oxygen is highly soluble in subcritical water. Molecular oxygen has been used as the reagent for the oxidation of alkyl aromatic compounds in the presence of different catalysts, such as MnBr.

Effects of electromagnetic radiation on neurogenesis and gene expression in amniocytes

Erdal, Nurten | Ay, Özlem İzci | Yıldırım, Didem Derici | Durukan, Hüseyin | Erdal, Mehmet Emin

The aim of the study was to investigate the genetic effects of commonly used radiofrequency on the amniocytes of pregnant women by examining the changes in the expression of genes related to signal transduction and neurogenesis induced by electromagnetic fields of radiofrequencies of 1800 and 2100 MHz by real-time PCR. Upon exposure of the amniocytes to electromagnetic radiation of 2100 MHz at high field strength, the expression levels of genes with important functions in the Wnt signaling pathways as well as neurogenesis-related genes were increased. The findings suggest that radiofrequency at high field strengths can have genotoxic effects during pregnancy.

Altan, Orhan

Novel phosphine oxides, (((3-methylpyridin-2-yl)amino)methyl)diphenylphosphine oxide (1) and diphenyl((pyrazin-2-ylamino)methyl)phosphine oxide (2), were synthesized and characterized. Phosphines ligands (3 and 4) were obtained by the reduction of 1 and 2 with AlH3, monitored by 31P NMR spectroscopy. Pd(II) complexes of 3 and 4 were synthesized and characterized (5 and 6). The catalytic activity of 5 and 6 was tested on the reaction of styrene with both activated and deactivated aryl bromides in air. The results of the catalytic experiments were discussed through DFT calculations.

Comparative analysis of mobile laser scanning and terrestrial laser scanning for the indoor mapping

Yiğit, Abdurahman Yasin | Ulvi, Ali | Yakar, Murat

Efficient three-dimension exploration of a complex indoor environment remains a difficult duration in mapping accuracy requirements for geometric data. Indoor and outdoor mapping, which has been done with classical measuring devices for a long time, has come a long way with the use of laser scanning technology in this field. Although terrestrial laser scanning (TLS) point cloud recording provides great convenience in indoor and outdoor mapping, it is disadvantageous in terms of time and cost. Therefore, in our study, we propose a new indoor mapping strategy with wearable mobile laser scanning (WMLS) approach, which uses the simultaneous localization and mapping algorithm, which has been tried recently, as an alternative to TLS point cloud. In this strategy, four test areas with different g...

Enrichment of copper and nickel with solid phase extraction using multiwalled carbon nanotubes modified with Schiff bases

Dogan Calhan, Selda

The behaviour of some Schiff bases in the presence of metal ions is very selective in complex formation. In this study, new, selective and easily prepared adsorbent materials have been developed. Multiwalled carbon nanotubes (MWCNTs) are quite suitable as supporting material for preparation of new solid phase adsorbents modified with Schiff bases due to their selective nature. Different Schiff bases were designed and synthesised as adsorbent agents for Ni(II) and Cu(II) ions, according to the literature, and MWCNTs were modified with these Schiff bases. The modification of CNTs was performed by adsorption from the alcoholic solution of Schiff base. The measurements of Ni(II) and Cu(II) ions were carried out using ICP-MS. Different parameters such as pH, model and eluent solution flow rates...

In this study, the coastal changes in Hersek Lagoon, have occurred in the 5 years (2015 to 2020) were examined. With the Modified Normalised Difference Water Index (MNDWI), the water areas in the lagoon were determined by object-based classification. When the changes are examined on a regional basis, it is seen that there are erosion and accretion areas were observed. Pearson's r value was examined between End Point Rate (EPR) and Linear Regression Rate (LRR) and a high correlation such as r = 0.921 was obtained. The maximum coastal change was observed as 18.74 m/year with EPR and 18.62 m/year with LRR.

Ameliorative effects of paricalcitol against 1800-MHz mobile phone radiation-induced skin damage in rats

Aktaş, Savaş | Çömelekoğlu, Ülkü | Demirbağ, Burcu | Kibar, Deniz | Söğüt, Fatma | Yalın, Serap

This study aimed to evaluate the protective role of paricalcitol, a vitamin D analog, against hazardous effects of 1800-MHz radiofrequency (RF) radiation on the skin of male Wistar albino rats exposed one h/day for 4 weeks. The maximum specific absorption rate was calculated as 0.0042 W/kg. Superoxide dismutase and catalase activity, collagen bundle thickness, breaking force, energy, and stress were decreased, while malondialdehyde level and mast cell number were increased. The exposure to 1800-MHz RF radiation caused a reduction in skin biomechanical quality through oxidative stress and mast cell activation. The administration of paricalcitol caused a significant improvement.
