In order to reveal the effect of the donor units on the structure-property relationship, three novel directly linked donor-acceptor type systems, 1-3, which are based on thiophene and pyridine conjugates, are designed, synthesized and characterized by spectroscopic methods. It is noteworthy that these D-A systems exhibit distinct electrochemical and optical features depending on the strength of the D-unit or the conjugation length. Furthermore, it is found that two of these novel systems, 2 and 3, can be used in both chromogenic and fluorogenic detection of Cu2+ among other ions.© 2013 Elsevier Ltd. All rights reserved. Source

In standard convention, the new complete orthonormal sets of (a)-exponential type orbitals (a)-ETOs) are introduced as functions of the complex or real spherical harmonics and L(a)-modified and L(p)-generalized Laguerre polynomials (L(a)-MLPs and L(p)-GLPs), nlm (̃r)= 23=2e/x 2L nl (x)Slm L nl (x) n l 1 (2n)1 1=2 xlL(p)n/l/1(x) where, 0 < <, x = 2r, p = 2l + 2, = n + l + 1 and is the noninteger or integer (< 2 for) frictional quantum number (< < 3 for p ° ). It is shown that the origin of the (p)-ETOs, L(a)-MLPs and L(p)-GLPs is the self-frictional quantum forces which are analog of radiation damping or self-frictional forces introduced by Lorentz in classical electrodynamics. The relations for the quantum self-frictional potentials in terms of (p)-ETOs, L(p)-MLPs, and L(p)-GLPs, respectively, are established. We note that, in the case of disappearing frictional forces (for p = 1 and = Z/n), the (p)-ETOs and eigenvalue are reduced to the Schrödinger's results in nonstandard convention for the hydrogen-like atom and, therefore, the (p)-ETOs become the noncomplete, i.e., (1) nlm o nlm. Here, the nlm is Schrodinger's wave function in nonstandard convention. As examples of an application of (p)-ETOs as basis sets, the calculations have been performed for the total energies of some atomic and ionic systems. © 2012 The Chemical Society of Japan. Source

The Tethyan Metallogenic Belt (TMB), extending from Europe through Anatolia to Iran, is one of the world's major metal producing belts, and consists of many sectors. Mineral deposits of the Biga Peninsula in northwestern Turkey exhibit, in many ways, the characteristics of mineral deposits found throughout the belt. Biga Peninsula tectonically forms the westernmost part of the Sakarya Zone and easternmost part of the Rhodope Zone at the intersection of Gondwana and Laurasia. The Biga Peninsula metallogeny research and exploration project created a GIS inventory of mineral deposits and prospects, and classified them genetically to evaluate the mineral deposit potential using genetic models based on descriptive data. The GIS database, consisting of 128 deposits or prospects, helped to generate new prospects and potential prospects. This field-based study indicated that the Biga Peninsula forms a prime target for gold-copper exploration not only in Turkey but in the world. The current economically significant mineral deposits of the Biga Peninsula were shaped by Cenozoic calc-alkaline magmatism, ranging between 52 and 18. Ma, and related to mainly collisional and post-collisional tectonic regime. Epithermal Au-Ag deposits including high-(HS), low-(LS) and intermediate-sulfidation (IS) styles, porphyry Au-Cu-Mo and base-metal skarn systems are economically the most important. Though there are no currently economic examples of some of them in the Biga Peninsula, other deposit types include Carlin-like distal disseminated Au-Ag, orogenic Au, especially listwanite hosted, volcanogenic Mn and U, lateritic (ferricrete) Fe deposits, carbonate replacement (CR) and placers. Several active metal mines, such as Balya, Arapucandere and Koru, are operating in the Biga Peninsula. Kucukdere Au-Ag deposit in Balikesir is the only gold mine in the Biga Peninsula, except for by-product gold produced from base-metal deposits. Results of the study show current total gold endowment of the Biga Peninsula including reserves and/or resources is 9.18. Moz gold [284.2. t] contained in twelve different deposits. Of these only 6 contain significant gold [> 0.3 Moz or 10 t]. Halilaga porphyry and Agi Dagi and Kirazli HS epithermal systems have an ongoing resource estimate, and Halilaga is a candidate to be one of the largest Cu-Au deposits not only in the Biga Peninsula, but in Turkey. Currently newly discovered Tepeoba is the largest porphyry Cu-Mo-Au deposit with known resources in the Biga Peninsula.Here, the first 40Ar/ 39Ar step-heating age data conducted on some of the major HS epithermal gold deposits and causative intrusives in the Biga Peninsula are reported. Geochronological results from this project, evaluated with previous studies, indicate at least 3 phases of porphyry and 2 phases of high-sulfidation epithermal gold mineralization in the Biga Peninsula. The most important mineralizing phases and related host rocks for gold mineralization range from 38 to 22Ma. The Oligocene is especially important for economic epithermal and porphyry systems in the Biga Peninsula, which is comparable to deposits in the Oligo-Miocene Serbomacedonian-Rhodope metallogenic belt of the Balkan Peninsula in SE Europe. © 2012 Elsevier B.V.

This study presents the concentrations and modes of occurrence of trace elements in 81 coal samples from the Çan basin of northwestern Turkey. The concentration of trace elements in coal were determined by inductively coupled plasma-mass spectrometry and inductively coupled plasma-atomic emission spectrometry. Additionally, traditional coal parameters were studied by proximate, ultimate, X-ray diffraction, and petrographic analyses. Twenty trace elements, including As, B, Ba, Be, Cd, Cu, Co, F, Hg, Mo, Ni, Pb, Sb, Se Sn, Th, Tl, U, V, and Zn, receive much attention due to their related environmental and human health concerns. The Çan coals investigated in this study are lignite to sub-bituminous coal, with a broad range of ash yields and sulphur contents. The trace element concentrations show variety within the coal seams in the basin, and the affinities vary among locations. The concentrations of B, Ba, Be, Cd, Cu, Co, F, Hg, Mo, Ni, Pb, Sb, Se, Sn, Tl, and Zn in Çan coals are within the Swaine's worldwide concentration range, with the exception of As, Th, U, and V. On the other hand, compared with world coals, the Çan basin coals have higher contents of As, B, Cu, Co, Mo, Pb, Th, U, V, and Zn. Based on statistical analyses, most of the trace elements, except for U, show an affinity to ash yield. Elements including As, Cd, Hg, Se, Cu, Mo, Ni, and Zn, show a possible association with pyrite; however, the elements Se, B, and Mo can be have both organic and inorganic associations. © 2011 Elsevier B.V.

Flower identification and recognition are tedious and difficult tasks even for humans. Image segmentation based on automatic flower extraction is an essential step for computer-aided flower image recognition and retrieval processes. Furthermore, there is a challenge for segmentation of the object(s) from natural complex background in color images. In this study, a novel performance optimization approach for image segmentation, i.e. simulated annealing-based mean-shift segmentation (SAMS), is proposed and implemented. It is based on the simulated annealing solution of quadratic assignment problem model treated as an image segmentation process using feature-based mean-shift (MS) clustering on color images. The proposed approach is designed to realize a global and unsupervised (i.e., fully automatic) segmentation. It is a modified and optimized version of Backprojection-based mean-shift segmentation (BackMS) method. In conducted segmentation experiments, the performance results of SAMS approach are compared with the ones of BackMS method. Comparison of overall performance results and statistical analysis (i.e., Wilcoxon signed rank median test) show that SAMS approach improves the performance of BackMS method. It is measured as 49.33% when using object bounding boxes and as 51.33% when using object pixel regions. © 2013 Elsevier B.V. All rights reserved. Source
