High-performance spectral-domain optical low-coherence reflectometry with an integrated arrayed-waveguide grating

The effect of discrete output channels and polarization dependency of an arrayed-waveguide-grating (AWG) spectrometer on spectral-domain optical low-coherence reflectometry performance is investigated

Polarization-independent optical low-coherence reflectometry with a non-birefringent arrayed-waveguide grating

The polarization dependency of an arrayed-waveguide grating (AWG) in an optical low-coherence reflectometry system is investigated. For mixed polarization, signal fading is observed at specific depths. This fading is eliminated by using a nonbirefringent AWG

Authoritarian Neoliberalism and Democratic Backsliding in Turkey: Beyond the Narratives of Progress

Unpacking the core themes that are discussed in this collection, this article both offers a research agenda to re-analyse Turkey’s ‘authoritarian turn’ and mounts a methodological challenge to the conceptual frameworks that reinforce a strict analytical separation between the ‘economic’ and the ‘political’ factors. The paper problematises the temporal break in scholarly analyses of the AKP period and rejects the argument that the party’s methods of governance have shifted from an earlier ‘democratic’ model – defined by ‘hegemony’ – to an emergent ‘authoritarian’ one. In contrast, by retracing the mechanisms of the state-led reproduction of neoliberalism since 2003, the paper demonstrates that the party’s earlier ‘hegemonic’ activities were also shaped by authoritarian tendencies which manifested at various levels of governance

2-s2.0-85087318250Objective: Obesity is the most important public health problem of the 21st century. The prevalence of obesity in the community has led people to search for weight loss. In addition to lifestyle changes such as increasing physical activity, eating behavior changes, different body weight protection methods are developed and many of these methods are offered under the name of weight loss products. The aim of this study is to determine the herbal product use approaches for weight loss in women and to determine the factors affecting the use of herbal products. Methods: This descriptive study was conducted on females aged 18-65, living in Denizli province, attending the sports courses twice a week. The research was carried out with 612 participants. The questionnaire was applied to individuals through faceto-face interviews. Results: Approximately half of females use herbal products (41,3%) and a great majority of the participants (70,4%) do not mention their products to their doctors or pharmacists. More than a half of the participants use of herbal products in the forms of tea 62,9%. Most of the participants (54,6%) buy such products from herbalists. It has been detected that 50,6% of the participants use herbal products everyday. Less than a half of them (35,2%) state that they get the necessary information and usage method from their neighbours and relatives. 26,3% of the participants have nausea-vomiting. 79,4% of the females advise the herbal products they use themselves to others. A great majority of them are married (n:439, %71,7) and have graduated from university (n:227, %37,1). Top five dry herbs are cinnamon (12,6%), flax seed (11,5%), oat (11,2%), black sesame (10,6%) and black pepper (8,5%). Lemon (22,9%), parsley (11,5%), tomato (8,3%), mint (7,8%) and avocado (6,9%) are mostly used as fresh herbs. Green tea (20,6%), sage (7,1%), linden (6,9%), cherry stalk (6,1%) and rosemary (5,2%) are preferred as herbal tees. Lemon (39,3%), cabbage (17,0%), onion (12,8%), garlic (11,7%) and tomato (4,2%) are used as herbal juice. Top six popular imported herbal drogs are herbalife (39,0%), green coffee (11,4%), pepper pill (10,4%), apple chromium (9,5%), golden berry (5,7%) and chocolate slim (5,7%). Conclusion: There are still deficiencies in supporting the effectiveness of the use of these products which are sold on various platforms. These products can lead to many side effects which can lead to death. In addition to the necessary regulations on herbal products, toxicological examinations and evidence-based data should be evaluated. © 2020 Refik Saydam National Public Health Agency (RSNPHA)

Influence of lithium-holmium co-doped on structural and electrical properties of BSCCO superconductor

Bi2Pb0.5Sr2Ca4Cu 6LixHoxOy (0.0?x?0.5) samples were prepared by doping with Li and Ho at changing ratios and using meltquenching method. Thus, the influences of different doping levels of Li and Ho on the structural and electrical properties of the BPSCCO compound have been investigated by electrical resistivity, Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and Energy Dispersive X-Ray Spectroscopy (EDX) techniques. It has been observed that, with increasing Li and Ho doping, the high-Tc Bi-(2223) phase gradually transforms into the low-T c Bi-(2212) and Bi-(2201) phases. However, It should be pointed out that these low-Tc superconducting phases are formed at all the doping levels, but increasing amount with increasing concentration of Li and Ho. Therefore, while the electrical resistivities in the normal states increase, the superconducting transition temperatures, Tc, hole concentrations, p, and the magnitudes of thermoelectric powers of all the samples decrease with increasing Li and Ho concentration x. As a result, the results suggest that with the increase in Li and Ho amount the superconductivities of all the samples are suppressed due to the destruction of the phase coherence by pair-breaking effects, or, to the hole filling mechanism with increasing x

Impact of small Er rare earth element substitution on magnetocaloric properties of (La0.9Er0.1)0.67Pb0.33MnO3 perovskite

In this work, the effect of Er substitution on the magnetic and magnetocaloric properties has been studied for (La0.9Er0.1)0.67Pb0.33MnO3 perovskite synthesized by the sol-gel procedure. Magnetization measurements performed as a function of both temperature and magnetic field in order to determine magnetic and magnetocaloric properties. The temperature dependence of magnetization measured under 5 mT magnetic field indicate that sample exhibits ferromagnetic (FM) to paramagnetic (PM) transition with increasing temperature. The Curie temperature (TC) decreases with Er-doping from 358 K for La0.67Pb0.33MnO3 to 349 K. From the isothermal magnetization measurements taken up to 5T around the TC in 3 K intervals, the magnetic entropy change (?SM) values of the sample have been determined for different magnetic fields. The ?SM max value has been calculated as 0.98, 1.73, 2.33, 2.85 and 3.23 Jkg-1K-1 for 1, 2, 3, 4 and 4.8 T, respectively. The type of magnetic phase transition has been determined as the second order from the slope of Arrott plots. © 2019 Elsevier B.V.This work is supported by the Research Fund of Çukurova University, Adana, Turkey , under grant contracts no.
