    Acrylamide exposure of infants and toddlers through baby foods and current progress on regulations
    (Elsevier Sci Ltd, 2022) Boyaci-Gunduz, Cennet Pelin
    Acrylamide is a thermal-process contaminant and found at different levels in various carbohydrate-rich foods processed at for babies and children since acrylamide-rich foods comprise an important amount of their diet. Consumption of acrylamiderich foods results in higher acrylamide-exposure levels of babies and children than adults due to their lower body weight. In recent years, with an increased number of exposureassessment studies and researches, acrylamide exposure of babies and children is very well defined. In that context, mitigation strategies have been conducted and also, some regulations have been implemented in some countries for baby foods. The aim of this study is to evaluate recent data about acrylamide levels and acrylamide exposure of infants (0-1 years old) and toddlers (1-3 years old) through commonly consumed baby foods in the last decade, and to discuss current progress on regulations.

    ELF-aware pre-service teacher education: practices and perspectives
    (Oxford Univ Press, 2020) Deniz, Esma Biricik; Kemaloglu-Er, Elif; Ozkan, Yonca
    English as a lingua franca (ELF) is a recent paradigm in ELT which acknowledges non-native varieties in their own right and NNSs as having their own unique characteristics rather than assessing them against an NS benchmark. Despite the changing needs of today's English language learners, there is little research on how to integrate ELF into pre-service teacher education programmes and English language teaching practice since there is a theory-practice gap due to lack of clear pedagogical descriptions and concrete classroom-driven data. This study presents an intensive educational model for pre-service teachers aiming to raise their awareness of the pedagogy of ELF, synthesizing theory with practice. It investigates how prospective teachers exposed to the ELF-aware teacher education model integrated ELF into their teaching and their viewpoints about the process. The entire process has been reported to contribute significantly to the participants' professional development as well as presenting several challenges.

    Special Issue: The International Conference on Raw Materials to Processed Foods
    (Wiley, 2019) Selli, Serkan; Kelebek, Haşim
    This special issue of Journal of Food Processing and Preservation contains a collection of extended and revised versions of 12 selected papers from The International Conference on Raw Materials to Processed Foods (www.rpfoods2018.org) held in Antalya, Turkey in 2018. RP-Foods Conference was inspired from the main concern of humans of all time which is all kinds of foods. Food is essential for us to live, grow, and function and in addition to these essential needs, it has an underestimated effect on the economy with daily produced crops. The consumption of raw materials has been carried out with a broad range of results comprising hunger satisfaction to nutrient supplement. This wide usage of raw materials naturally necessitates food processing technologies to be developed. Food processing is one of the main events that paved the way into the sedentary lifestyle and civilization. Food processing is already a crucial field and topics like public health, sustainability challenges, and preference of consumers require this field to change and improve continuously. With this reason in mind, the food industry is decisively looking for different procedures to produce and store crops where the researchers put forward in the development of new innovative and novel technologies.

    Polar Codes with Higher-Order Memory
    (Maik Nauka/Interperiodica/Springer, 2018) Afser, H.; Delic, H.
    We introduce a construction of a set of code sequences {C-n((m)) : n 1, m 1} with memory order m and code length N(n). {C-n((m))} is a generalization of polar codes presented by Arkan in [1], where the encoder mapping with length N(n) is obtained recursively from the encoder mappings with lengths N(n - 1) and N(n - m), and {C-n((m))} coincides with the original polar codes when m = 1. We show that {C-n((m))} achieves the symmetric capacity I(W) of an arbitrary binary-input, discrete-output memoryless channel W for any fixed m. We also obtain an upper bound on the probability of block-decoding error P-e of {C-n((m))} and show that Pe=O(2-N) is achievable for < 1/[1+m(phi - 1)], where phi (1, 2] is the largest real root of the polynomial F(m, ) = (m) - (m - 1) - 1. The encoding and decoding complexities of {C-n((m))} decrease with increasing m, which proves the existence of new polar coding schemes that have lower complexity than Arkan's construction.

    Current-driven magnetization switching under zero field in Pt/Ta(wedge)/CoFeB/MgO multilayers
    (Aip Publishing, 2022) Akyol, Mustafa; Yu, Guoqiang; Wong, Kin; Wang, Kang L.
    The switching of perpendicularly magnetized ferromagnets via current-induced spin-orbit torques is of great interest because of its potential applications in memory and logic devices. However, the in-plane electric current itself is not enough to switch the magnetization. In addition to the electric current, an in-plane external magnetic field is required for magnetization switching. This limits the usage of such devices in spintronic applications. Here, we work on the current-driven perpendicular magnetization switching in the Pt/Ta(wedge)/CoFeB/MgO multilayer. The structural symmetry is broken in both z-axis and in-plane due to the wedge Ta layer, which results in a field-like spin-orbit torque. The beta( z )value extracted from the slope of the offset field vs current density increases with Ta layer thickness (< 1.0 nm) and then decreases up to z-axis asymmetries that enable the current-driven magnetization switching without the need for a magnetic field. We showed switching of the magnetization with a perpendicular magnetic anisotropy, switching in a wide range of Ta layer in Pt/Ta(wedge)/CoFeB/MgO multilayer.

    Comparative study of hybrid artificial neural network methods under stationary and nonstationary data in stock market
    (John Wiley & Sons Ltd, 2019) Dosdogru, Ayse Tugba
    In this study, a new methodology is proposed to automatically determine six parameters of artificial neural network using population-based metaheuristics. We considered following three issues: What is the effect of used metaheuristic on performance? Which parameters are mostly selected? Is there a difference between the forecasting results when using stationary or nonstationary dataset that are selected according to the augmented Dickey-Fuller test statistics? Based upon results of performance measures, proposed method leads to significant opportunities to forecast stock market more effectively. We also expect proposed methodology can provide remarkable advantages for other complex, dynamic, and nonlinear forecasting problems.

    Turkey: A Rising CIVETS Star?
    (Igi Global, 2015) Egeoglu, I. Efe; Christiansen, Bryan
    The Republic of Turkey represents solid business opportunities for Foreign Direct Investment (FDI) and local investors within the so-called CIVETS (Colombia, Indonesia, Vietnam, Egypt, Turkey, South Africa) economic bloc, an entity which has relatively little coverage in extant academic literature. This chapter outlines 12 disruptive industries that can play a major role in Turkey's future economic development by providing business and job opportunities from project-based export-import activities. The chapter also covers other important subjects such as human resource management, building global Turkish brands, and education/training. The chapter concludes with some suggestions for future research directions regarding research and development, diversity management, English as a Foreign Language training, and cultural intelligence.

    Functionalized highly electron-rich redox-active electropolymerized 3,4-propylenedioxythiophenes as precursors and targets for bioelectronics and supercapacitors
    (Royal Soc Chemistry, 2021) Karazehir, Tolga; Sarac, Baran; Gilsing, Hans-Detlev; Gumrukcu, Selin; Eckert, Jurgen; Sarac, A. Sezai
    In order to combine capacitive properties with processability, e.g. solubility in organic solvents, poly(3,4-propylenedioxythiophene) derivatives containing different functional groups like oxyphenyl methanol (-OPhCH2OH), oxybenzyl (-OBz), bromide (-Br) and tosyl (-OTs) were synthesized and electropolymerized as thin films from acetonitrile (ACN) using Et4NBF4 as an electrolyte. Multifunctionality in the substitution pattern of the polymer exhibits a similar trend between monomer oxidation potentials and specific capacitance (C-sp) vs. crystal size. The presence of pi-pi stacking interactions in the polymer structures plays an important role in building the crystal structures. The same order of flat band potential and C-sp values are observed for -OBz < -Br < -OTs < -OPhCH2OH substitutions. The structures of PProDOT-OBz and PProDOT-OPhCH2OH resemble each other much more than those of PProDOT-Br and PProDOT-OTs. Impedance measurements were conducted at different applied biases in order to define a Mott-Schottky analysis revealing the dependence of the semiconducting properties on the type of substituent present in the PProDOT derivative.

    Effect of B4C Content on the Mechanical and Tribological Performances of Polypropylene
    (Polish Acad Sciences Inst Physics, 2014) Dike, A. S.; Mindivan, F.; Mindivan, H.
    Boron carbide (B4C) reinforced polypropylene (PP) was prepared by twin-screw extrusion and injection molding. In the present study, the effect of B4C content on the mechanical properties and wear behavior of the PP composites was studied. The tribological properties of the PP composites were investigated by a reciprocating wear tester under dry friction conditions. The results of the mechanical and wear test showed that the hardness and yield strength increased with increasing B4C content, while the incorporation of B4C into PP largely increased wear and friction under dry sliding. The composites have higher wear rates in comparison with unfilled PP and the greater the difference, the greater are the sliding velocities.
