    The Middle East Technical University (METU) Ankara Campus is one of the earliest and most prominent modern-period university campuses that resulted from an architectural competition in the 1960s in Turkey. However, METU Campus, as a modern-era heritage place, faces various threats, including pressure for new urban development. In addition, the increasing number of students and contemporary educational needs require changes in the physical infrastructure and campus settings. Thus, all these threaten the tangible and intangible values of the Campus. In this regard, conserving the METU Campus requires a multidimensional approach that considers a wide range of values and problems; herein, the Geographic Information Systems (GIS) becomes a useful tool for dealing with this complex work. Accordingly, the METU Campus GIS Project [METU_GIS] was developed to document and understand the multidimensional characteristics of the METU Campus, assess its values, and propose solutions to current issues while considering its values and potentials. Accordingly, the METU_GIS defines conservation policies and strategies that ensure the conservation and sustainability of the Campus as a living modern heritage place. Furthermore, the METU_GIS is a GIS-based conservation management plan created for a modern period campus for the first time in Turkey. Hence, it became an essential basis and a tool for conserving and managing the METU Campus as a modern living heritage place. All in all, the METU_GIS proves that Geographic Information Systems (GIS) are essential tools that can be used in the documentation, conservation, and monitoring of modern heritage places

    A shape tailored gold-conductive polymer nanocomposite as a transparent electrode with extraordinary insensitivity to volatile organic compounds (VOCs)

    In this study, the transparent conducting polymer of poly (3,4-ethylenendioxythiophene): poly(styrene sulphonate) (PEDOT:PSS) was nanohybridized via inclusion of gold nanofillers including nanospheres (NSs) and nanorods (NRs). Such nanocomposite thin films offer not only more optimum conductivity than the pristine polymer but also excellent resistivity against volatile organic compounds (VOCs). Interestingly, such amazing properties are achieved in the diluted regimes of the nanofillers and depend on the characteristics of the interfacial region of the polymer and nanofillers, i.e. the aspect ratio of the latter component. Accordingly, a shape dependent response is made that is more desirable in case of using the Au nanorods with a much larger aspect ratio than their nanosphere counterparts. This transparent nanocomposite thin film with an optimized conductivity and very low sensitivity to organic gases is undoubtedly a promising candidate material for the touch screen panel production industry. Considering PEDOT as a known material for integrated electrodes in energy saving applications, we believe that our strategy might be an important progress in the field.Peer reviewe

    Introduction: The aim of this study was to investigate the effectiveness of treatment for quitting smoking and Maras powder use in patients aged 60 years or older, and to examine factors likely to be effective in stopping tobacco use.Materials and Method: Out of 178 patients aged 60 years or older, who presented to our outpatient clinic for quitting smoking and Maras powder use, 115 for whom there were no missing data were enrolled in this study.Results: Out of 100 patients who presenting to quit smoking, 76 (76.0%) were male and 24 (24.0%) were female. Fifteen patients who presenting to quit Maras powder use were all male. The mean age of the participants was 62.98±4.30 years (min=60, max=81) and did not differ between the female and male participants (p=0.351). Forty-eight smokers (48.0%) gave up smoking during treatment, but 52 smokers (52.0%) were still smoking during treatment. Eight Maras powder users stopped using the powder after treatment, but seven Maras powder users continued using Maras powder despite treatment.Conclusion: We found that a high proportion of patients aged 60 years or older stopped using tobacco after treatment. Determination to stop tobacco use, appropriate treatment and regular follow-up play an important part in quitting tobacco use. © 2014, Geriatrics Society. All rights reserved

    Conformers of β-aminoisobutyric acid probed by jet-cooled microwave and matrix isolation infrared spectroscopic techniques

    β-aminoisobutyric acid (BAIBA) has been studied in isolation conditions: in the gas phase and trapped into a cryogenic N2 matrix. A solid sample of the compound was vaporized by laser ablation and investigated through their rotational spectra in a supersonic expansion using two different spectroscopic techniques: broadband chirped pulse Fourier transform microwave spectroscopy and conventional molecular beam Fourier transform microwave spectroscopy. Four conformers with structures of two types could be successfully identified by comparison of the experimental rotational and (14)N nuclear quadruple coupling constants with those predicted theoretically: type A, bearing an OH⋯N intramolecular hydrogen bond and its carboxylic group in the trans geometry (H-O-C=O dihedral ∼180°), and type B, having an NH⋯O bond and the cis arrangement of the carboxylic group. These two types of conformers could also be trapped from the gas phase into a cryogenic N2 matrix and probed by Fourier transform infrared (IR) spectroscopy. In situ irradiation of BAIBA isolated in N2 matrix of type B conformers using near-IR radiation tuned at the frequency of the O-H stretching 1st overtone (∼6930 cm(-1)) of these forms allowed to selectively convert them into type A conformers and into a new type of conformers of higher energy (type D) bearing an NH⋯O=C bond and a O-H "free" trans carboxylic group
